Documents are accessible on our own network, but they can’t be accessed by computers outside the network. Using of cloud computing, the software programs aren’t run from one’s personal computer, but are rather stored on servers accessed via the Internet. Cloud Computing provides resources and capabilities of Information Technology (e. g. , applications, storages, communi cation, collaboration, infrastructure) via services offered by CSP (cloud service provider).Cloud Computing has various characteristics as shared infrastructure, self-service, pay-per use model, dynamic and virtualized, elastic and scalable. Cloud computing in academic environment will be benefitted by every student and staff where lots of collaboration and safety of data is needed in academic. Academic has various departments and many semesters where lots of students need to access the computing a need for highly available up-to-date software and hardware is must. Cloud computing has the capacity of scaling and elasticity which is perfect for such an environment.Keywords: Cloud Computing, Web service, Virtualization, Grid Computing, Virtual Computing Lab, higher education institutions I. INTRODUCTION Cloud computing growth has taken all the attention of various communities like researches, student, business, consumer and government organization. Big data is the main reason for comi ng of cloud computing in the show, everyday lots of data in the size of PETA bytes are uploaded in the digital world which required lots of storage and computing resources.Cloud Computing is a marketing term which is also known as utility computing deliver the service as software, platform and infrastructure as a service in pay-as-you-go model to consumers. Berkeley report says on this services as â€Å"Cloud computing, the long held dream of computing as a utility, has the potential to transform a large part of the IT industry, making software even more attractive as a service. Education has been gradually expanded, and the education object has slowly turned to social staff.The teaching method from black board to online is growing fast than ever. An online tutor which helps has to take class in any hour is an advance of learning using technology. E-learning and online solution is what we required in education environment. With the increasing number in receiving education, a series of new problems have emerged. For example: As teaching methods change, the existing teaching-learning methods cannot meet demand; and with the constant expansion of education, the existing teaching facilities also need to constantly update.When Cloud Computing appears, it provides a new solution to establish a unified, open and flexible network teaching platform and reduce the hardware input [10]. Internet is the resource where we can transform cloud computing, it can deliver the most advanced software and educational materials, hardware resources and services to students and educators in even the most impoverished or remote school districts in the state, without the need for advanced IT expertise at those locations. At the same point, it does more for significantly less, providing needed relief for currently strained education budgets [12].IT companies are eager to encourage educational adoption of cloud computing; for example, Google Apps for Education Suite comprises Google Mail , Calendar, Talk, Docs, Sites and Video with zero cost and without advertisements [1], According to a Forrester cost analysis [9], Google Apps is more effective than a Microsoft Exchange e-mail. Based on CSU research, the costs of software licensing, server hardware and staffing to support 50,000 users by using Microsoft Exchange e-mail (the number of undergraduate e-mail accounts at CSU) would be $9,774,000 per year [2].The cost of Google Apps for businesses is $50 per user per year, or with 50,000 users, $2,500,000 per year. The cost of Google Apps Education Edition, however, is $0 per year [2]. As we can see from this example, the industrial cloud computing solution for the educational institution already gave an estimated savings from about $9,774,000 per year to $2,500,000 per year in the â€Å"businesses version† or to zero cost of licensing and equipment in the â€Å"educational version†.Taking into account the last two examples, we can see that both approaches, industrial (or commercial) and non-commercial cloud computing solutions can be successfully employed within educational institutions and another example, IBM launched IBM Cloud Academy that 97 Volume 2 No. 2, February 2012 ISSN 2223-4985 International Journal of Information and Communication Technology Research  ©2012 ICT Journal. All rights reserved http://www. esjournals. org s provide a global forum for educators, researchers and IT professionals from education industry to pursue cloud computing initiatives, develop skill and share best practices for reducing operating costs while improving quality and access to education. In this way users do not need to buy a server, only need to purchase related â€Å"services† can create an efficient network teaching platform [10]. Using of cloud computing in academicians in universities are not aware of benefits and characteristic of minimizing the cost of cloud computing.From an ITmanagement view, it radically reduces resource man agement costs —including electric power, cooling and system management personnel, while driving up the utilization of servers and software licenses, which in turn reduces purchasing requirements [12]. Lab Problem The maintenance of dozens of computers in the labs becomes a burden for the system administrator. This paper proposed diskless cluster computing environment in a computer classroom and the development of teaching network management system in computer classroom.In this paper we discuss the â€Å"Cloud Computing† paradigm and characteristics, service and deployment models, implementations of cloud services at universities, and various opportunities and benefits of Cloud Computing for universities & academic institutions. Finally, we suggest a design prototype of Cloud Computing for Academic Environment. IV. Benefits of Cloud Computing †¢ †¢ †¢ †¢ †¢ †¢ †¢ Reduced implementation and maintenance costs Increased mobility for a glo bal workforce Flexible and scalable infrastructures Quick time to market IT department transformation (focus on innovation vs.Maintenance and implementation) â€Å"Greening† of the data center Increased availability of high-performance applications to small/medium-sized businesses [3] Cloud Computing II. RELATED WORKS Invent of Internet changes the way we use of computer. From mail to shopping we all depend on this huge group of network computer. Cloud computing has entirely changes what the internet means. Powerful of desktop application is available on net and storage is available online wherever we go from any device. ELearning and web 2. 0 learning totally changes of education system.Teacher and student work together in online project not in school or colleges but from home also. Teaching has never been easy without cloud computing [10]. Definitions of cloud is defined by many expert, but the National Institute of Standards and Technology (NIST) definition is a generally accepted standard: â€Å"Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (such as networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. 4 More simply, a cloud can be considered to be a collection of hardware, software and other resources that can be accessed over the Internet, and used to assemble a solution on demand (that is, at the time of the request) to provide a set of services back to the requester. When analyzed the definitions, there is a consensus on few key points; (1) Cloud Computing ensure on-demand access to a pool of computing resources, (2) dynamically scalable services, (3) device and media independency, and (4) easier maintenance of applications due to do not need to be installed on users’ computers.Cloud computing should be elasticity and scalability. Figure (1) [5], adapted [4] shows six phases of computing paradigms, from dummy terminals/mainframes, to PCs, networking computing, to grid and cloud computing. In phase 1, many users shared powerful mainframes using dummy terminals. In phase 2, stand-alone PCs became powerful enough to meet the majority of users’ needs. In phase 3, PCs, laptops, and servers were connected together through local networks to share resources and increase performance.In phase 4, local networks were connected to other local networks forming a global network such as the Internet to utilize remote applications and resources. In phase 5, grid computing provided shared computing power and storage through a distributed computing. III. PURPOSE OF RESEARCH Students’ learning is no longer confined within the classroom in the era of e-learning 2. 0[11]. The environment of IT education could be improved to let student access learning resources anywhere. IGNOU (Indira Gandhi national Open University) is the good exa mple of e-learning.The free software can be adopted for constructing the cloud computing service for the environment of IT like OpenOffice. org such as word processing, spreadsheets, and presentations. Only a browser is needed for students to connect to the cloud computing service for learning. 98 Volume 2 No. 2, February 2012 ISSN 2223-4985 International Journal of Information and Communication Technology Research  ©2012 ICT Journal.

CLOUDS COMPUTING IN UNIVERSITIESA Cloud-computing service that will let universities and colleges build custom private clouds that can be integrated into public cloud services [10]. Three main factors interests in Cloud Computing: 1) rapid decrease in hardware cost and increase in computing power and storage capacity, and the advent of multi-core architecture and modern supercomputers consisting of hundreds of thousands of cores; 2) the exponentially growing data size in scientific instrumentation/simulation and Internet publishing and archiving; and 3) the widespread adoption of Services Computing and Web 2. applications. For example, a university student taking a college math course could access a cloud from his or her door room, to obtain a physical or virtual server (with the necessary storage) and a copy of Maple or MATLAB software running on it to use for homework or a class project. Likewise, an elementary school teacher could access the same cloud to request one virtual machine for each of his or her students running Mathmedia software, as part of his or her classroom instructional activities [12].

PRIVATE CLOUD FOR UNIVERSITIES Private cloud (also called internal cloud or corporate cloud) is a marketing term for a proprietary computing architecture that provides hosted services to a limited number of people behind a firewall. Advances in virtualization and distributed computing have allowed corporate network and datacenter administrators to effectively become service providers that meet the needs of their â€Å"customers† within the corporation.Marketing media that uses the words â€Å"private cloud† is designed to a ppeal to an organization that needs or wants more control over their data than they can get by using a third-party hosted service such as Amazon's Elastic Compute Cloud (EC2) or Simple Storage Service 99 Volume 2 No. 2, February 2012 ISSN 2223-4985 International Journal of Information and Communication Technology Research  ©2012 ICT Journal.

Business Applications Figure 3: Example of Private cloud in organizations Hosted in the cloud are probably the most promising cloud service and the most interesting topic for computer science education because it can give businesses the option to pay as they go while providing the big-impact benefit of the latest technology advancements [7]. The involvement of students in such type of projects with real customers is mutually beneficial to students, fa culty and businesses. †¢ Personal Productivity Applications VIII. PROPOSED EDUCATIONAL CLOUD INFRASTRUCTER PROTOTYPEDesign of Cloud Infrastructure needed the following service and application †¢ Collaboration Application Moving email and PIM (personal information manager) to managed service providers. IDC says that 67 percent of survey respondents believe collaboration applications such as email, chat, conferencing and collaborative file sharing solutions such as SharePoint are a great fit for the cloud because they reduce costs in the short term [7]. For collaboration application GMAIL apps come in handy without any charges. For our International conference I have uploaded spreadsheet for collaboration work here any person involves in maintaining the office work is done online. †¢ Web Serving CIchannelinsider. com predicts that hosted mobile applications through carriers and mobile software providers as well as document-editing applications like those from DataViz an d Quick office are also expected to gain traction [7]. Mobile phone is widely used among student and staff application or service develop in university campus can be used in mobile device also which means every time we are connected to university campus. A university mini Facebook would be a great deal to share and update news among the student and staff.IX. SUGGESTED ACADEMIC ENVIRONEMNT CLOUD Moving web servers, management and analytic tools to the cloud is also at the top of the prioritized list, because this will reduce maintenance costs and reliance on subscription models as well as improve rapidness of deployment [7]. Cloud Sever is the key part of the computing platform to ensure its scalability. All the resource can be store at this cloud server which includes online videos, audios, pictures, and course wares etc. This web server infrastructure in cloud computing can share resources for educational and research purposes. Cloud Backup Some companies like Asigra are moving dis aster recovery and back-up to the cloud. As IDC says, in spite of cloud security concerns, 60 percent of enterprises are still considering moving back-up off-site to the cloud to protect against natural disasters, IT mishaps, power outages and other unforeseen catastrophic events [7]. Drop Box is a free service to take back up of our data in cloud environment it enable synchronize with any device wherever drop box is install. A cloud backup service can The study aims to suggest a cloud environment for academic purposes.Academic environment is where lots of computer is uses and many of them are not in use which lead to malfunction of computer and maintenance is highly complicated due to lack of staff. The propose cloud computing environment will be of storage infrastructure, development platform, and software delivering. Changing of hardware resources and lots of storage capacity is required in academic environment computing lab [11]. Many universities and colleges started using thin client technology to reduce the cost but thin client is not suitable for high performance computing.Office applications, programming language, and multimedia developing courses are not only for IT department but too many departments also. Also every year, the new versions of applications were used for courses with respect to the needs of industry. As a natural result of this progress, new software cause new hardware costs [11]. Installing and maintaining will be free from everyone. Whenever any new software appears many of hardware don’t support and everyday many bytes of storage are required where loss of data is very high due to improper handling of computer by many student. Student mistakenly or unknowingly deletes other data.By using cloud computing in academic environment collaboration among the staff and student will be more like using Google docs or any other private 100 Volume 2 No. 2, February 2012 ISSN 2223-4985 International Journal of Information and Communicatio n Technology Research  ©2012 ICT Journal.

By giving a virtual machine to everyone and a secure password student and staff will work on their own virtual machine and if anything happens will only crash the virtual machine not the entire system.Below Fig. 4 represents the proposed cloud computing for academic environment. By this way, lecturers will focus their basic tasks and not lose their workforce. With this cloud computing environment student can work from their lab as well from home. Where there data and application will be available always. [2] Dan R. Herrick. 2009. Google this! : using Google apps for collaboration and productivity.

CONCLUSION Cloud computing is a solution to many problem of computing. Even we are in IT ages complication of computing has created much disaster to computer world. Lots of crisis has happen in business world as well as in academic environment. Data security, storage, processing power is limited while using traditional computing. Data are also in risk and not available all time. But by using of cloud computing the entire problem is solve.Computer in academic environment must have the latest hardware and software. Due to cost many couldn’t fulfill the availability of resource to student and staff by using cloud computing in academic environment we can solve all the issue. Cloud computing is new technology suitable for any environment. ACKNOWLEDGEMENT We thank Karpagam University for motivating and encouraging doing our Research work in a Successful.

How Can We Help Promote tourism in Malaysia Essay

Malaysia has been visited by thousands of tourist from all over the world every year. But tourism in Malaysia can be further developed by promoting many aspects that the country has. Malaysia is a land that has been bestowed with greenery, mountains, beaches and rivers. Its natural landscape itself is a great attraction for foreigners. The sandy beaches in Penang Island, Port Dickson and Morib are holiday retreats for Westerners who are deprived of the sun and sea due to the cold weather in their countries. The wind whispering through the tall shady casuarinas and lapping sea waves are ideal places for visitors in search of peace and tranquility. There are natural places which have special attractions for the foreigners to look and enjoy. The Kuala Selangor fireflies is a must to visit. The fireflies in Kuala Selangor are the largest colony in the world. Visitors have to take a boat ride in late evenings to see the fireflies, which lit up the trees in the dark. The nocturnal tours in the boats would be a unique experience for any traveler. This unique attraction can be highlighted in the brochures and the websites in the Internet. World- class theme parks like the Sunway Lagoon and Mines Wonderland must be highlighted also. The Sunway Lagoon, which was once a tin mine, has been transformed into a recreational park. There are also five-star hotels in these places where visitors could enjoy their stay there. Kuala Lumpur the capital city is the ideal place to shop because it promises variety , value and convenience all in one place. Malaysian items like pewter and batik can be found at various places for different levels of budget. Names of places and malls so that the visitors have and idea where to go for shopping for certain items. All these aspects can be highlighted in the media especially in the Internet so that visitors can get the right information about Malaysia and would want to visit our country.

Hedda Gabler Essay

In the beginning when the reader meets Hedda Gabler, one can see how she is quite a high maintenance character by how she complains that the maid has† opened the door. I’m drowning in all this sunlight. † (Ibsen 1469). Exerting her power over her husband, George Tesman, she demands him to close the curtains, which he does complacently. Later Hedda notices an old hat lying on the chair and worries that someone may have seen it. When she learns that the hat belongs to Miss Tesman, George’s dear aunt, she does not apologize for her comment which shows her tendency to belittle others, even if they are family. Hedda utters to her husband, â€Å"But where did she get her manners, flinging her hat around any way she likes here in the drawing room. People just don’t act that way. † (1418). The author depicts Hedda as a neurotic woman who criticizes the actions of others in an attempt to demonstrate her self- imposed superiority over others. Her pretentious comment introduces the theme of a high and mighty character, which readers will begin to hate, who eventually succumbs to the pressure of appearing perfect in society. In the scene where George and Hedda receive news that Mrs. Elvsted, an â€Å"old flame† of Tesman, will be visiting, Hedda remembers her as the one with â€Å"that irritating hair she’d always be fussing with† (1418). By this remark, the reader can predict that Hedda, very jealous of Mrs. Elvsted, will attempt to flaunt her superiority over her throughout the rest of the play. Once Mrs. Elvsted arrives, and she and Hedda are alone they chat about a variety of topics: marriage, love, and most importantly, a man named Eilert Lovborg, with whom Mrs. Elvsted is in love. Admitting her feelings of loneliness in her marriage, Mrs.  Elvsted strives to justify her relationship with Lovborg and mentions how happy he makes her when he allows her to help him write, as he is a published author. However, Mrs. Elvsted is unsure of the future of their relationship because â€Å"the shadow of a woman† stands between them. This unidentified woman was going to shoot Lovborg when they broke up. As Hedda learns of this, she comments, â€Å"That’s nonsense. People just don’t act that way here. † (1424). Yet, an astute reader can tell that Hedda is hiding something: she was, in fact, the woman who had previously tried to shoot Lovborg. Ibsen does this to show that Hedda acts in a manner that contradicts her snooty statements. Later in the play when Lovborg visits Hedda, he confronts her by asking why she married George because it is apparent that she does not love him. Then he inquires if she ever loved him while the two had previously been in a relationship, and he reminisced about how he confessed so many secrets to her. â€Å"Ah, Hedda, what kind of power was in you that drew these confessions out of me? † (1440) he asked. Mischievously, she responds, â€Å"You think it was a power in me? (1440). All the while, Hedda takes pleasure in knowing that she can control others by exerting her power over them. Deeper into their conversation, the reader learns that when the two enjoyed a secret friendship, Hedda had threatened to shoot Lovborg, but she did not because she feared the scandal it would have caused. Once again, Hedda proves to be overly concerned of what society thinks. On the outside, she appears to fit the mold of how a woman in society should behave; yet, internally, she struggles with a predisposition to act in a contradicting manner of what society regards as acceptable behavior. She is propelled by this internal conflict during the entire play. Earlier in the play, the reader inferred that Hedda envies Mrs. Elvsted because of her relationship with Lovborg; therefore, the reader expects to see Hedda parade her superiority over Mrs. Elvsted. True to her character, Hedda rips out the pages in Lovborg’s manuscript, which Mrs. Elvsted helped him write, and throws them into the stove. Crazed, Hedda exclaims, â€Å"I’m burning your child, Thea! You with your curly hair! Your child and Eilert Lovborg’s. I’m burning it! I’m burning your child† (Ibsen 1456). Right before this manic event, Hedda urges Lovborg to commit suicide, gives him one of her pistols, and expresses her desire for him to do it â€Å"in beauty† (1456). Once she persuades Lovborg to commit suicide, Hedda can no longer suppress her internal conflicts and shoots herself in the head. The reader can assume that Hedda commits suicide beautifully, as she hoped Lovborg would do. Her motto of â€Å"people just don’t act that way,† proves to be false because her actions are exactly what she says people do not do. Throughout Hedda Gabler, the main character possesses much contempt for her husband, insults others, and resents a former acquaintance. Despite her concern with society’s opinion of her, she feels trapped within society’s standards to act a certain way. Yet, in doing so, she becomes dejected from others and society as a whole. Repeatedly, she uses the following phrase: â€Å"People just don’t act that way,† in an attempt to suppress her internal desires to be like one of those people. By the end, Hedda cannot live torn between two different realities; she chooses to behave like one of those people, and she commits suicide- in beauty, of course.

Bike Thieves at Arizona State University Essay Example | Topics and Well Written Essays - 1750 words

Bike Thieves at Arizona State University - Essay Example In addition, the student is faced with a financial burden to replace the bicycle or find an alternative means of transport, and until they do they are faced with significant inconvenience in commuting from one place to another. Students are the group most highly affected by this theft, as many are low in income, and as a consequence find replacing their bicycle difficult, and may not be able to afford alternative means of transportation. Hendricks, L. (2010, September 29). Bike thieves in high gear, Az Daily Sun. This article was published in the Arizona Daily Sun, a newspaper which serves Northern Arizona and the Flagstaff district. The writer of the article was the assistant editor. As a consequence of the source of the information, it can be considered to be reliable and well researched because there are standards required of any reporter publishing in a newspaper. The author reports on the role that is played by the police in recovering bicycles stolen from Northern Arizona Unive rsity and an approach to reduce the number of bicycle thefts that are occurring. Thefts are common at the University, so much so that the police department has a separate category to track these as for other thefts. Officer Jerry Rintala comments that most thefts happen as a consequence of owners not locking up their bicycle as they only plan to be gone for a short period of time, or using poor quality locks, which are easy to remove with the use of bolt cutters. In an attempt to reduce this, the police and University security have initiated a campaign across campus to inform students about the benefits of using quality locks and keeping their bicycles locked when they are not in use. As it is a crime of opportunity, this has the potential to greatly reduce the number of bicycle thefts that are occurring. In addition, a bicycle registration service has been brought back to campus which is free to all student, faculty, and staff at the University. This involves registering the physic al description and the serial number of the bicycle, as well as a photo if desired, with the police, allowing them to identify the bicycle if it is found. The combination of these two techniques should result in the significant decrease in the number of bicycles that are stolen and an increase in both the likelihood and the speed in the bicycle being returned to its owner. Crime Prevention Unit. (2011). Don't let your bike get ripped off. Theft Prevention Retrieved October 13, 2011, from http://www.tempe.gov/cpu/bike%20theft.htm This article was published online on the website for the City of Tempe, Arizona, under the section of the Crime Prevention Unit, theft prevention. There is no author given for the short article, however, the fact that it hosted on the government website indicates that the tips which the articles give are in line with the standards recommended by the city authorities. Furthermore, the fact that the article is hosted on the Tempe City governmental site indicat es that the statistics that are given are likely to be correct. The City of Tempe has had severe problems with bicycle theft, with more than 650 reported stolen in 2010 alone. Like the Arizona State University, many of the thefts were a consequence of the bicycles not being locked. The city offers registration of bicycles through bicycle stores rather than through the police, with the aim of identifying the ownership of bicycles if they are recovered.

Writer's choice - Research Paper Example Business opportunities in UAE are not just for people within Middle East, but also to overseas investors. Foreign investors in Middle East nations are encouraged since their foreign business is a great boost to the economy. There are numerous free trade areas, particularly in Dubai, and that is the reason why trade and commerce is at peak in those countries. People come from many countries to shop in UAE because they get cheap and quality goods there. Additionally, introducing a business in the UAE is very straightforward and easy. UAE encourages investors to invest in the oil and gas –rich country. Another reasons why investors are attracted in investing in UAE is because the taxation mostly non-existence or minimal. The Middle East governments have a long- run strategy that concentrate heavily on the growth of upcoming businesses. They have business policies that are truly favorable to all investors. The tax-free atmosphere is encouraging for new and emerging enterprises (Sp raggon, 2014). This paper will discuss a type of small business opportunity that can be capitalized in United Arabs Emirates. Additionally, the paper will discuss the business significance and its benefits to the society. This paper also discusses how the small business can help the economy and business sectors at large. Because of the many large-scale businesses in UAE, there is a huge demand for experts who offer financial services like bookkeeping, accounting, and auditing. Persons with solid backgrounds in any of these financial fields will make a lot of profit by opening a business that will provide financial services to other businesses in UAE. The UAE financing sector is adequately resourced to cope up with domestic and global stress situations and has dealt with the current global financial chaos comparatively well. Looking at future, a report indicated that UAE finance sector would continue to indicate a

Compare the concept of Adam and Eve and the original sin in Research Paper

Compare the concept of Adam and Eve and the original sin in Christianity and Judaism - Research Paper Example ( Penny Catechism, Article15, undated) The same document went on to say that:- All mankind has contracted the guilt and stain of original sin, except the Blessed Virgin and her Divine Son, through whose foreseen merits she was conceived without the least guilt or stain of original sin.( Penny Catechism , Article 117, undated) ) . There are two accounts of creation recorded in Genesis. These represent two strands of a very old story based upon long standing oral traditions. These have become the creations myths of both Christianity and the Judaism in which they had their founding. Genesis, Exodus, Leviticus, Numbers and Deuteronomy are described in Judaism as the Pentateuch, and these five books are traditionally said to be the work of Moses. His is death is however actually recorded in Deuteronomy 33, and it is generally considered that a number of different strands wrote theses books in the form we now have them in the 6th or 7th century B.C.E., round about the time of King Solomon . In Genesis Chapter One man is created and in Genesis Chapter Two the creation of Adam is described in more detail. He is made from the earth or clay. The word for ‘formed’ is one which would be used to describe how a potter creates a pot form clay ( Genesis 2 v 7, commentary, Bible New International Version, 2008). The word Adam is linked to the Hebrew word ‘Adamah’ which mean red and it is suggested that this means he was created from red clay ( Mandel 2013) . The story describes how God bought each animal to Adam, who gave then their names. He could not find a suitable helper among them. In Genesis 2 v 18 God says :- It is not good for man to be alone. I will make a helper suitable for him. Genesis 2 v 21, 22 describe the creation of Adam. She is made form part of Adam. Eve is called in Hebrew ‘Haya’ which means ‘live ‘ or ‘to live (Meaning and etymology of the name Eve, undated) . In Genesis 3 v 20 it states :- Adam named his wife Eve, because she would become the mother of all the living. In one version the two appear to be created simultaneously, but in the second version she come later. By the time both stories were written down each would have carried its own authority and could not be discarded. Living in the Garden of Eden with her husband, Eve is approached and then tempted by the serpent. She yields to the temptation offered and eats the forbidden fruit, as well as some to her husband. After this it as if they have woken up, as become aware of their nakedness and make themselves clothes. Later ( Genesis 3 v 12) Adam puts the blame on Eve. As a result God tells Eve that she will have pain in childbirth and will become subject to her husband ( Genesis 3 v 16. It is often interpreted that only Eve who is admonished, but in Genesis 3 v 17ff Adam, too is told what will happen to him as the result of his disobedience. According to Jewish teaching Eve was not created at the same time as Adam becaus e God knew that she would become a reason for complaint ( Eve, Jewish Encyclopedia ,1906). These is also a tradition of another help meet being created before Eve , Lilith , but she goes her own way and refuses to be the wife of Adam ( Hampshire County Council, undated) . According to another Jewish rabbinic tradition Eve was tempted first, as women were more likely to give in than men. Despite Eve’

What do Advertisements Tell Young People They Should Value Essay

What do Advertisements Tell Young People They Should Value - Essay Example Advertising has been part of American life for centuries, and has certainly always had some kind of effect on the behaviour of Americans in a wide variety of ways. Throughout the past ten to twenty years, however, the amount of advertising exposure and kind of advertising has changed significantly, and may have an increased effect on American youths. It is incredibly difficult to construct a causal relationship between advertising and behaviour, something that advertisers have used to their advantage to fight regulation throughout history, from the cigarette era to today. The problems of determining causal relationships are myriad, but most simply rest on the well known idea that correlation is not causation: wearing your favorite team’s jersey and them winning does not indicate any causal relationship between your jersey choice and your team’s success. Furthering the complexity of this problem is the fact that advertising in fact mirrors many of the issues inherent to many forms of media, such as film and television, in, for instance, constructing unrealistic ideas of beauty. Advertisers, for instance, are often blamed on helping to cause eating disorders, while there may be many different societal and media factors at work in those issues. To construct a causal relationship, one must therefore go much further than simply analyzing correlation (though correlation certainly plays some part in the analysis). Through analyzing the behaviour advertisers, the explosion of new media, the psychological makeup of young adults, and the correlation between youth behaviour and advertising, it is possible to construct a causal relationship between advertiser’s construction of the ideals of beauty and negative behaviour among young adults, such as the development of eating disorders. The first thing that must be unequivocally establishes is the fact that advertising does, in fact, affect behaviour. This is its whole point of the entire industry, to lea d people to buy products. There are various interpretations of the role of advertising. The most generous would say that advertising merely influences behaviour through demonstrations of a product’s usefulness to its client; advertising affects behaviour merely through informing (). The least generous would say that advertising twists people’s emotions, world view, and so on, in order to manipulate them into buying a given product (). The truth is probably somewhere in between, that advertising does rely on a product’s abilities, but that advertising also manipulates viewers to a significant extent. That advertising affects people’s behaviour can be seen merely by the size of the industry: it is a multi-hundred billion dollar industry worldwide (Shaman, 2012), and a single thirty second spot in the Super Bowl can sell for â€Å"upwards of $5 million† (Shaman, 2012). There is no way corporations would spend this kind of money on advertising if they were not confident in its

Rhetorical Critique Essay Example | Topics and Well Written Essays - 1000 words

Rhetorical Critique - Essay Example If the needs of a particular group are met then it would be said that the writer was effective in his work. In this case they have to employ the language in an effective manner so as to meet a certain rhetoric situation (Wilhoit 41-45). Jonathan Riel the author of Obama and Reagan: A Rhetoric critique and declaration of not war in Libya targets the same population in addressing the challenges and issues affecting the American society. In his first article that touches on Obama and Reagan, he tends to draw two parallel rhetoric lines between the two leaders. His focus on Obamas campaign turns out to be rhetoric. According to him Obamas mode of communications changes immediately the campaign is over. In this case it implies that governing cannot be the same as running or organizing for a campaign. For instance, Obama employs the use of impersonal style of communication which on his side differs a lot from the persuasion used for the public especially if one is running a campaign. This case greatly differs from the type of communication of any governmental official once elected in office. His speech was compared to Reagan style of speech that was challenging. The author of this blog tends to be bias against Obamas administration; he tries to capture the attention of his audience by portraying Obamas organization as an organization that seeks the merciful help of his citizens which is only applicable when seeking for votes but his reach by the citizens on his office seems to be impossible. The main aim of bringing this point is to ridicule the administration and also to provoke the citizens (Lanham 58). The author tries to use persuasive and provoking to the audience by pointing out that Obama has a very poor view of Reagan administration. In this regard, he does not come out with proper reasoning to support this but instead he says that Obama portrayal of Reagan leadership was that of one who could not steer the American economy forward. His argument seeks to dema nd and seek his audience attention. Nevada interview has been known to have attracted a huge crowd of scholars of the Rhetoric communication. His style of communication during the interview employed the use of keen attention by the public as persuasive. The author also tries to portray how other leaders have viewed Obama (Riehl n.d). His idea of the American dream is critiqued because Reagan was the official party property of the Republican. The American 40th president presented his speech which was viewed by the blogger as rhetorical act the speech was made to the public which demonstrated no signs of campaigns. Obama is believed to have integrated all the elements to form his own rhetoric. Reagan speech revolved much on the future of the America on the other hand Obama opinion is to overcome the presidency of the opposing party which he relates to future. Obamas speech was concerned with uniting all races of the American people. He preaches the message of hope of the American peop le. This message is also preached by Reagan on his public addresses. These two share the same feature in the sense that they both emphasize the need for positive growth in the American society (Lanham 71-80). This is seen as aspirations of the people of the people. Reagan had an aspect of blaming the fore fathers this aspect was absent on Obama this is portrayed in his speeches where he demonstrates how the slaves were able to fight

Critically assess the postwar consensus thesis Essay

Critically assess the postwar consensus thesis - Essay Example There was however, some conflicts noted between the parties concerning the postwar consensus. The parties had consent to similar principles as well as aims but had differences in styles and emphasis (Bogdanor, 2011, para 1-9). This paper therefore has the focus of analyzing the concept of post war consensus with attention on the policies inside this concept as well as understanding the collapse of the concept as reviewed through scholarly works. Much of the evolution in the concept is attributed to in differences postulated by partisan political parties as well as the administration over the period. The concept of welfare state comprehensive in Great Britain dates back to mid Second World War as was developed in the reposts of William Biveridge in 1942. This is therefore the postulated foundation upon which the concept of postwar consensus is claimed to be built. Therefore, the policy formulations that resulted from the government of the labor party formed a basis on which the consen sus was formed on. The government undertook and implemented various policies which were distinct to the leadership history of the country. The conservative party had great influence in the industrial charter, which followed the successful formation of the previous government by the labor party. Moreover, the acknowledgement of the various policy frameworks by the party as they were designed and implemented by the party in power made the conservative party to reserve many of the policies during the 1947 industrial charter (Anon, nd, p. 217-222). Great Britain categorizes the historical perspective into two phases which span through the consensus period as well as the period after the consensus was broken and the period runs to today. The consensus period spun the years 1945 to 1979 after which the post consensus period set in and has been up to the current period (Matthijs, 2008, p. ii). After the end of the Second World War, the consensus that settled in and had a guiding commitment to full employment, industries were nationalized, government undertook to control the economic demand through application of the Keynesian techniques. Moreover, the government adopted the social welfare in a system of self-sponsored technique. The period after the election in 1945 saw the labor party form the government and adapted reformation policies and not revolutionary policies (McCulloch, 1985, p. 465). Economist and other analysts interpreted the system of government adopted by the labor party government as reformists as against revolutionalists. Non-revolutionary alliances of trade unions as well democratic socialists were the foundations, which formed the Labour party. The governance structure that succeeded the election of the Labour party to office mainly comprised of the political class of persons who had gotten into politics in the early 20th century. This period, which span across the years 1945 to 1951, was a characteristic period in the history of the country as it is credited to be the period in which many of the legislations in Britain were formulated. The government also placed policies which oversaw many industries nationalized until the 1980s. The welfare state as was a characteris

FMC Green River case study Organizational Behavior Essay

FMC Green River case study Organizational Behavior - Essay Example In that case organizational change must be planned, monitored and controlled throughout its lifecycle, with completion occurring on full implementation and evaluation. Organizational change decisions are often complex, multi-faceted, and involve many different stakeholders with different priorities or objectives. Most people, when confronted with such a problem will attempt to use intuitive approaches to simplify complexity until the problem seems more manageable. In the process, important information may be lost, opposing points of view may be discarded, elements of uncertainty may be ignored -- in short, there are many reasons to expect that, on their own, individuals (either lay or expert) will often experience difficulty making informed, thoughtful choices about complex issues involving uncertainties and value tradeoffs. This fact, and the tendency of change issues to involve shared resources and broad constituencies, means that group decision processes are called for. These may have some advantages over individual processes: more perspectives may be put forward for consideration, the chances of having natural systematic thinkers involved is h igher, and groups may be able to rely upon the more deliberative, well-informed members. However, groups are also susceptible to the tendency to establish entrenched positions (defeating compromise initiatives) or to prematurely adopt a common perspective that excludes contrary information - a tendency termed "group think." (McDaniel's etal., 1999). For change management projects, decision makers may currently receive four types of technical input: modeling/monitoring, risk analysis, cost or cost benefit analysis, and stakeholders' preferences. However, current decision processes in Green River typically offer little guidance on how to integrate or judge the relative importance of information from each source. Also, information comes in different forms. While modeling and monitoring results are usually presented as quantitative estimates, risk assessment and cost-benefit analyses incorporate a higher degree of qualitative judgment by the project team. Structured information about st akeholder preferences must be presented to the decision-maker, and should be handled in a perfect manner that minimizes the difficulty of defending the decision process as reliable and fair. If the structured approaches are employed, they may be perceived as lacking the flexibility to adapt to localized concerns or faithfully represent minority viewpoints. As a result,

Failed States and Effective Division of Labor Strategy in the Future Assignment

Failed States and Effective Division of Labor Strategy in the Future Post-Conflict Reconstruction Projects - Assignment Example Somalia, a country rated as number one failed state in the world, is either controlled by the foreign military or by the Al-Shabab militia. Warships from several countries patrol the waters off Somalia to curb the pirates (Kaplan, 2010). It is estimated that about 2 million people have fled Somalia and sought asylum elsewhere (Foreign Policy, 2010). This has also been seen in Afghanistan where the Taliban and foreign troops have more control of the country. Failing or failed states experience an economic decline, this is the case in Zimbabwe and North Korea where tyrannical regimes have stolen money from their economies leaving their markets on a verge of collapse. This has led to inequality with few elites benefiting from the national resources while the majority remains poor. This has also been witnessed in Democratic Republic of Congo and Sudan. In Niger, a country also rated as a failing state, the government cannot provide vital services such as healthcare and education leading to a high illiteracy rate and high infant mortality rates. Zimbabwe has experienced a high rate of brain drain and it is estimated that one out five Zimbabweans has left the country in such of greener pastures. Failed states have also experienced a high rate of human rights deprivation as is the case with Sudan where brutality has been employed to subdue rebelling regions. This has led the president to be indicted for war crimes (Foreign Policy, 2010). Division of labor among states, international institutions, and non-governmental organizations should follow the following guidelines to ensure that they are effective in the context of future post-conflict reconstruction projects. Leadership roles should be left to the people of that country. The international community should just come in to provide assistance in solving the problems of that country.

Library and Its Uses Essay Example for Free

Library and Its Uses Essay The root-meaning of the word library is a room or building containing a collection of books for reading. But as there are now circulating or travelling libraries in many countries, the world has undergone a change in its meaning. By the word now indicated a collection of books for reading or reference; Different kinds of libraries: There are kinds of libraries personal, public and institutional. Personal library A personal library is one which belongs to a private person, generally of sufficient means. Such libraries grow out of such person’s taste for knowledge and, sometimes, for fashion. There are, of course, small scale private libraries owned by solvent lawyers, educationists and persons of literary taste. But such libraries contain books on some particular subject or subjects chosen according to the taste and interest of their owners. Public library A public library is one which is open to the public. In order to cater to the taste and interest of all classes of people, a public library has to contain books on different subjects and varieties. Such libraries may be seen in large numbers in every country. Most of these libraries are managed or subsidized by their states. The British Museum library of London and the Central library of Moscow are instances of public libraries. Again, many such libraries have been set up in England and America by philanthropic people like Mr. Carnegie, the American millionaire. Institutional library An institutional library is one which belongs to an institution such as a university, a college, a school, a chamber of commerce, a club or a governmental department. Such a library is open to the members of the institution concerned and, therefore, generally contains hooks which are needed by them most. Importance of library As acquisition of knowledge depends mostly on reading, man has to read as necessarily as he has to eat. It adds to what he has already learnt and makes him strong and fit for rude battle of life. But for financial difficulties most of the persons who are keen on reading cannot purchase the books they need to read. Hence arises the importance of libraries. Had there been no libraries, both public and institutional, such persons would have been deprived of their reading. The teachers and the students, in like manner, would be badly affected if their institutions had no libraries of their own. Conclusion Libraries attract people to read and thus create the habit of reading and- stimulate the thirst for more and more knowledge. But for the libraries, there would be no authors, no poets, and no thinkers. The libraries thus help in the advancement of learning and expansion of knowledge. The library has another very important use. No research work is possible without a well equipped library containing valuable books of all ages, rare manuscripts and old records. A library of this type is thus of incalculable help in throwing light on unearthed subjects. Time passes in an unbroken continuity as does the water of the river. The books of the libraries are a record of this continuity. They thus enable us to know how human society has developed in thought and action step by step.

Understanding The Childhood And The State Sociology Essay

Understanding The Childhood And The State Sociology Essay The aim of this essay is to critically analyse both case studies by Virginia Morrow using arguments from the New Sociology of Childhood. The first part of the essay will discuss the concept of new sociology of childhood by explaining what it is, why it came about and what it main claims are. It will then move on to explore the findings of the above mentioned qualitative research of a group of children between 8 and 14 years of age in relation to their perspective on what they believe families to be. Children as social actors and childrens participation are key notions in what is considered as a modern day discourse. The implications discourses have in the ways in which children are portrayed and treated within society and the influence the actions taken by people and the judgement taken by them are often the subject of social constructionists. It is also well documented that different cultures can also have different perception, so can different situations and circumstances. In recent years, researchers have developed innovative methods for undertaking research with children. It has been customary to carry out research methods which have not directly involved children, for example, the study of children on a large scale and this has led to some disagreement by some sociologist because it is seen as carrying out a survey on children rather than with children. As an alternative, researchers have shifted towards the importance of giving the child a voice as social actors and being central in any research practise. It could be argued that most sociological policies and theories have in the past regarded children as being totally dependent, incapable, and dependent on their families to function successfully within a society. However, by adopting a childrens right perspective which is compatible with theoretical developments in the new sociology of childhood can mean that children have the power, skills, knowledge and resources to protect them. Children have been identified within the international framework of human rights as deserved of special consideration. As quoted by J. Eekelar à ¢Ã¢â€š ¬Ã…“the language of rights performs an important function. It acknowledges that there are certain things which we should provide for children, not just because adults think it would be nice if they had them, but because we are prepared to recognise that children want them, or can reasonably be assumed to want themà ¢Ã¢â€š ¬Ã‚ . (J.Eekelar Why Children? Why Rights? 2003) According to (James and Prout 1997) children are referred as active social agents and reliable informants of their own experience, who construct and shape the social structures and processes of their lives. Followers to this theory pay much attention to how children perceive the world around them and that they have their own distinctive way of looking at family life whereby the relationship is seen as a two way process with the child and the parent have a shared influence on any decisions taken. The research, by Morrow proposes that the majority of children do not want to make decision but rather would prefer to make a contribution to ther decision making process. None the less, there are some theorists who do not consider children as having sufficient protection even today. One of the sociologists is Melanie Philips who makes a case that the traditions of parenthood in the UK has broken down and that childhood simplicity has been destabilized by those with open mind which in turn could mean that children are given too many powers and rights. Other would suggest that the concept of cnew theory of childhood has become much more complicated and that there is an indication that the idea of a traditional childhood is yet again being lost. It is argued that this is not because of lack of understanding but through the lack of economic equality. Combined with the sophisticated and business-like way of living, it could be believed that childhood has somewhat been reduced as a result to the exposure to more adult information creating a child that is much more interested in everyday materialistic objects, and as such à ¢Ã¢â€š ¬Ã…“expelled from the garden of childhoodà ¢Ã¢â€š ¬Ã‚  (Postman, 1983) According to (Leacock 1981), within the new sociology of childhood, one of the key elements is that children should be considered as social actors, and by doing this, children are then taken from the idea of being objects, and to be studied on the basis that childrens beliefs and experiences do give insight into the meaning of childhood (Callinicos,1993). The research by Virginia Morrow (1998) was undertaken to explore two current phenomena . Firstly, that children of today experience quite varied family settings on their way to adulthood The second phenomena was in relation to the changes that have occurred in recent sociological theories whereby children should be listened to and importance given to what they have to say. The study looked at what childrens perceptions were on the family unit and how this might differ between cultures and background. It appeared that for many of the children, regardless of their ethnic background, their life revolved around their family or the extended family. One of the main findings was that childrens view in the main does not concur to what is considered as stereotypical notion of what a nuclear family is. Another key finding was that all the children included words such as care,support love and respect when describing what characteristics of family. Again this was though regardless of ethnic background, where they came from or their gender. A difference was found between children of different ages, as younger children saw having children and being in a marriage as the basis to a family and backed this up with examples from their own families. Older children were more ready to look at things outside their own domain. Many of the children referred to the term relations when describing their family and many were aware that individuals were related in different ways such as through marriage or genetically. In general, children explained that families were important to them and they saw their own family as any other family in general. When the question of who was important to them, the answer was parents, especially their mothers because they provide love and care. For some of the children, their sisters and brothers were seen as important to them. It appeared from their reactions that friendship was very important so some older children, especially girls. Finally, when asked about being listened to and being able to give their opinion, the children needed to be involved in decision making and have their say in what happens to them. Some considered that they were being listened to by their families while other did not. Some of the older children however, did mentioned that making a decision was not an easy task. On reflection therefore, the aim of this essay was to analyse the above mentioned case studies taking the new sociology of childhood into consideration. It could be said that discourses offer different and contrasting ways of thinking about children and childhood and as a consequence how they are viewed and treated by society. What this discussion serves to highlight is that there are conflicting thoughts surrounding the concept of childhood and that there is no clear right or wrong way of looking at what childhood conveys.

Malaysian construction industry system

Malaysian construction industry system INTRODUCTION The Malaysian construction industry is undergoing a transitional change from an industry employing conventional technology to a more systematic and mechanized system. This new system is now known as the Industrialized Building System (IBS). This new method of construction can increase productivity and quality of work through the use of better construction machinery, equipment, materials and extensive pre-project planning. This study becomes very necessary since there is yet no organized body, which can provide the necessary information on the building cost comparison between the conventional system and industrialized building system in Malaysias construction industry. This study also addresses the building cost comparison of the conventional system and industrialized building system of formwork system. It provides the details building cost between the conventional system and the formwork system and indicates which of the two is cheaper. The data were collected through questionnaire s urvey and case study, which consisting of institutional buildings. Through the statistical testt-test it is shown that there is a significant difference in cost saving for the conventional system as compared to the formwork system (industrialized building system). The Malaysian construction industry is undergoing a transitional change from an industry employing conventional technologies to a more systematic and mechanized system employing the latest computer and communication technologies. This is vital for the future health of the industry, given the trend towards global competition and the advent of the k-economy. The Industrialized Building System (IBS) has been introduced in Malaysia since the 60s by the use of precast concrete beam-column elements. Since the demand of building construction has increased rapidly, it is necessary to innovate a construction method, which speeds up the building construction process. To sum-up, in general, the IBS is a methodology whereby a local construction industry is driven towards the adoption of an integrated and encouraging key players in the construction industry to produce and utilize pre-fabricated and mass production of the building at their work sites. This will help to enhance the efficiency of construction process, allowing a higher productivity, and quality, time and cost saving. The construction cost of a building using precast components should be assessed in its overall context. The traditional method of costing by material quantities with a fixed factor for labor cost can lead to incorrect estimation. For example, if labor usage is halved, this will more than compensate for a 10% material increase. More importantly, there is saving in time. Also, if properly designed and executed, precast can lead to much better quality of work. The overall cost impact of precast has therefore to take all these factors into consideration. With the rising costs of labor and less assurance of dependable skilled manpower, the trend is that precast construction will become increasingly competitive compared to cast-in-place construction? PRECAST CONCRETE CONSTRUCTION Introduction Every construction material system has its own characteristics which to a greater or less extend influence the layout, span length, construction depth, stability system, etc. This is also the case for precast concrete, not only in comparison to steel, wood, masonry structures, but also with respect to cast in-situ concrete. Theoretically, all joints between the precast units could be made in such a way that the completed precast structure has the same monolithic concept as a in-situ one. However, this is a wrong approach one, which is very labour intensive costly. If the full advantages of precast concrete are to be realized, the structure should be conceived according to its specific design philosophy: Long spans, appropriate stability concept, simple details, etc. Designers should from the very outset of the project consider the possibilities, restrictions advantages of precast concrete, its detailing, manufacturer, transport, erection serviceability stages before completing a design in precast concrete. Precast concrete system enables faster programmed times not affected by weather or labour shortages. Improves buildability early enclosure of dry envelope enables follow-on trades to start sooner. Produces a high standard of workmanship in factory conditions reduces potential for accidents, addresses on-site skill shortage. Has a high quality finish that can be left exposed concretes thermal properties can be exploited in low-energy buildings. PRIMARY FUNCTIONS Keep water out Prevent air leakage Control light Control radiation of heat Control conduction of heat Control sound SECONDARY FUNCTIONS Resist wind forces Control water vapor Adjust to movement Thermal and moisture expansion or contraction Structural movements Resist fire Weather gracefully Easy to install Architectural precast concrete provides architects with an exciting medium when designing facades for a wide range of buildings, from healthcare facilities to shopping malls, commercial office buildings to sports stadiums. Precast concrete provides: Complete thermal protection Continuous air/vapour barrier Effective rain screens Superior lifespan Reduced construction schedule and on-site labour High quality control standards Numerous finish options and colours CATEGORIES OF PRECAST BUILDING SYSTEMS Precast buildings constitute a significant fraction of the building stock in the republics of the former Soviet Union and Eastern European countries. Depending on the load-bearing structure, precast systems can be divided into the following categories: Large-panel systems Frame systems Slab-column systems with walls Precast concrete floor Large-Panel Systems The designation â€Å"large-panel system† refers to multistory structures composed of large wall and floor concrete panels connected in the vertical and horizontal directions so that the wall panels enclose appropriate spaces for the rooms within a building. These panels form a box-like structure (see Figure 1). Both vertical and horizontal panels resist gravity load. Wall panels are usually one story high. Horizontal floor and roof panels span either as one-way or two-way slabs. When properly joined together, these horizontal elements act as diaphragms that transfer the lateral loads to the walls. Depending on the wall layout, there are three basic configurations of large-panel buildings: Cross-wall system. The main walls that resist gravity and lateral loads are placed in the short direction of the building. Longitudinal-wall system. The walls resisting gravity and lateral loads are placed in the longitudinal direction; usually, there is only one longitudinal wall, except for the system with two longitudinal walls. Two-way system. The walls are placed in both directions. Thickness of wall panels ranges from 120 mm for interior walls to 300 mm for exterior walls. Floor panel thickness is 60 mm. Wall panel length is equal to the room length, typically on the order of 2.7m to 3.6 m. In some cases, there are no exterior wall panels and the faà §ade walls are made of lightweight concrete. A typical interior wall panel is shown in Figure 2. Panel connections represent the key structural components in these systems. Based on their location within a building, these connections can be classified into vertical and horizontal joints. Vertical joints connect the vertical faces of adjoining wall panels and primarily resist vertical seismic shear forces. Horizontal joints connect the horizontal faces of the adjoining wall and floor panels and resist both gravity and seismic loads. Depending on the construction method, these joints can be classified as wet and dry. Wet joints are constructed with cast-in-place concrete poured between the precast panels. To ensure structural continuity, protruding reinforcing bars from the panels (dowels) are welded, looped, or otherwise connected in the joint region before the concrete is placed. Dry joints are constructed by bolting or welding together steel plates or other steel inserts cast into the ends of the precast panels for this purpose. Wet joints more closely approximate cast-in-place construction, whereas the force transfer in structures with dry joints is accomplished at discrete points. Frame Systems Precast frames can be constructed using either linear elements or spatial beam-column subassemblages. Precast beam-column subassemblages have the advantage that the connecting faces between the subassemblages can be placed away from the critical frame regions; however, linear elements are generally preferred because of the difficulties associated with forming, handling, and erecting spatial elements. The use of linear elements generally means placing the connecting faces at the beam-column junctions. The beams can be seated on corbels at the columns, for ease of construction and to aid the shear transfer from the beam to the column. The beam-column joints accomplished in this way are hinged. However, rigid beam-column connections are used in some cases, when the continuity of longitudinal reinforcement through the beam-column joint needs to be ensured. The load-bearing structure consists of a precast reinforced concrete space frame and precast floor slabs. The space frame is construc ted using two main modular elements: a cruciform element and a linear beam element. The cruciform element consists of the transverse frame joint with half of the adjacent beam and column lengths. The longitudinal frames are constructed by installing the precast beam elements in between the transverse frame joints. The precast elements are joined by welding the projected reinforcement bars (dowels) and casting the concrete in place. Slab-Column Systems with Shear Walls These systems rely on shear walls to sustain lateral load effects, whereas the slab-column structure resists mainly gravity loads. There are two main systems in this category: Lift-slab system with walls Prestressed slab-column system Precast columns are usually two stories high. All precast structural elements are assembled by means of special joints. Reinforced concrete slabs are poured on the ground in forms, one on top of the other. Precast concrete floor slabs are lifted from the ground up to the final height by lifting cranes. The slab panels are lifted to the top of the column and then moved downwards to the final position. Temporary supports are used to keep the slabs in the position until the connection with the columns has been achieved. In the connections, the steel bars (dowels) that project from the edges of the slabs are welded to the dowels of the adjacent components and transverse reinforcement bars are installed in place. The connections are then filled with concrete that is poured at the site. Most buildings of this type have some kind of lateral load-resisting elements, mainly consisting of cast-in-place or precast shear walls, etc. In case lateral load-resisting elements (shear walls, etc.) are not present, the lateral load path depends on the ability of the slab-column connections to transfer bending moments. When the connections have been poorly constructed, this is not possible, and the lateral load path may be incomplete. Another type of precast system is a slab-column system that uses horizontal prestressing in two orthogonal directions to achieve continuity. The precast concrete column elements are 1 to 3 stories high. The reinforced concrete floor slabs fit the clear span between columns. After erecting the slabs and columns of a story, the columns and floor slabs are prestressed by means of prestressing tendons that pass through ducts in the columns at the floor level and along the gaps left between adjacent slabs. After prestressing, the gaps between the slabs are filled with in situ concrete and the tendons then become bonded with the spans. Seismic loads are resisted mainly by the shear walls (precast or cast-in-place) positioned between the columns at appropri ate locations. Precast concrete Floor The principle advantages of precast floors are speed of construction, absence of scaffolding, large variety of types, large span capacity, economy. Precast floors can also be classified according to their manufacture into totally partially precast floors. Totally precast floors are composed of units, which are totally cast at the plant. After erection, the units are connected to the structure the longitudinal joints are grouted. In some cases a cast in-situ structural topping screed is added. Partially precast floors are composed of a precast part a cast in-situ part. Both parts are working together at the final stage to achieve the composite structural capacity. The main totally precast floor roof types are described hereafter. CONVENTIONAL IN-SITU CONSTRUCTION Conventional Construction Method Conventional construction encompasses traditional forms of structural load-bearing elements; typically composed of concrete, brickwork and structural steel. We are well-versed in all forms of conventional construction and have substantial in-house capacity. The majority of our commercial and unique residential products to date have utilized conventional methods of construction. A number of designers that we have worked with tend to express the structural elements of the construction, from exposed beams, cantilevered slabs and stairs, to exposed structural steelwork. This requires a high degree of accuracy as well as a high level of workmanship; both of which are easily attained using our in-house skills. Conventional building method is defined as components of the building that are pre-fabricated on site through the processes or timber or plywood formwork installation, steel reinforcement and cast in-situ. Conventional buildings are, mostly built of reinforced concrete frames. The tr aditional construction method uses wooden formwork. It is much more costly for construction, which includes labor, raw material, transportation and low speed of construction time. Cast-in-situ Construction Method This system is suitable for a country where unskilled labor is limited. There is no heavy machinery or high technology involved. The system is technically applicable to almost all types of building. Formwork is used as a mould, where wet concrete, is poured into a temporary system. The temporary system also acts as a temporary support for the structures. The objective of in-situ method is to eliminate and to reduce the traditional site based trades like traditional timber formwork, brickwork, and plastering and to reduce labor content. A carefully planned in-situ work can maximize the productivity, speed and accuracy of prefabricated construction. Cast in-situ method uses lightweight prefabricated formwork made of steel/fiberglass/aluminum that is easily erected and dismantled. The steel reinforcement is placed within the formwork as they are being erected and concrete is poured into the mould. When the concrete is set according to the required strength the mould is dismantled. The w orkers can be trained easily to erect the moulds and set the steel reinforcement. Its advantages over the traditional construction method are, its low skill requirement, can be quickly constructed, maintenance is low, structure is durable and cost can be less. In-situ method is to eliminate and reduce the traditional site based trades like traditional timber formwork, brickwork, plastering and to reduce labor content. Carefully planned in-situ work can maximize the productivity, speed and accuracy of prefabricated construction. The formwork system is based on the combination of pre-fabrication and in-situ conventional construction, which features the utilization of permanent concrete for elements instead of conventional timber formwork. Differences Between In situ and Precast Construction Method Labour   Ã‚  Ã‚  Ã‚  Ã‚  Precast construction method only use semi-skilled workers and dont use skill or unskilled- worker in construction process. Economies are generated through reduced requirements for formwork, access scaffolding and less reliance on wet trades. Reduced on-site supervision by the main contractor is also a saving. So for precast construction method, labours are not use 100 percent for making formwork, access scaffolding, and handle wet concrete. Due to speed of construction, gives earlier return on investment, freeing up the project critical path and allowing earlier completion. It is estimated that a precast structure takes up to 20% less time to construct than a similar cast in situ structure, using labour can be late because of rest time and energy of a labour. For quality and accuracy, precast construction methods will more quality n accuracy than in situ. This ensures that reinforcement bars are accurately located and that clients receive high quality products man ufactured to controlled dimensional tolerances. Precast method delivers a high performance product with a quality appearance. Have a high quality finish that can be left exposed concretes thermal properties can be exploited in low-energy buildings because all of the equipment are made up in factory.   Ã‚  Ã‚  Ã‚  Ã‚  In situ construction method use skilled worker, semi-skilled worker, and un-skilled worker in construction process. Labour can amenable to almost any design and labour can alteration the design in last minute construction process. Design can proceed as the structure is built because labour takes a time to build. Construction can proceed independently of weather conditions because workers still can proceed the work even though whether are not good. Construction process is easily used for two way structural systems because labour used two ways structural system in construction process. It is not necessary to pay for crane on site because of labour can take instead of crane functions. Wastage Environmental and manufacturing conditions at a precast concrete plant are easily monitored. The production of precast concrete elements takes place under controlled conditions in enclosed factories. This makes the control of manufacturing, waste, emissions, noise levels, etc. easy compared with the same processes at a building site. The raw material consumption is similar for similar qualities of concrete, whether the production takes place in a factory, at a ready-mix plant or at a building site. The raw material waste in precast concrete production is very small. The process of preparing mild steel reinforcement may be the same for a precaster as for a contractor at a building site, except that precasters will usually have less waste. This results in better utilization of the steel and less consumption of natural resources. Surplus materials are generated during the production of precast elements. Much surplus material is recyclable, and consists mainly of hardened concrete with or without reinforcement, steel reinforcement and pieces of structural steel, plywood and other wooden materials, fresh concrete (from production and washing of equipment), slurry from the sawing of concrete, insulating materials (mineral wool and polystyrene), oil etc. from machinery and paper and other packaging materials. The amount of surplus material varies between factories and different types of production. Studies in the Scandinavian countries have shown that the magnitude is typically about 100 kg of surplus material per m3 of concrete produced. About 40% of the surplus material is fresh and hardened concrete and about 45% is wastewater from washing equipment and sawing slurry generated during hollow core slab production. It is possible to collect and sort different types of surplus materials in precast plants. Excess materials that can be recycled and reused include steel, wood, insulating materials, oil, paper and other packaging materials. Wood can be sorted out, cut and used as industrial firewood, or used for other construction purposes. Buildings are constructed with traditional cast in-situ concrete, using timber formworks. Building that timber formwork was the major contributor to construction waste, accounting for 30% of the total identified waste. Wet trades, such as concreting, masonry, plastering and tiling on-site were considered as the second major waste generator, accounting for 20% of the total on-site waste generated. A recent study demonstrated that the ‘off-cuts from cutting materials were a major cause of wastage during construction. Waste also arises as a result of design concepts and decisions. Case studies in Sri Lanka In the construction industry, it is well known that there is a relatively large volume of material being wasted due to a variety of reasons. The problem of material waste on construction sites is not an isolated issue and is of environmental concern. Therefore, waste minimization has become an important issue in the construction industry. The aim of this research was mainly to identify the pre-cast contribution to the construction waste minimization in the Sri Lankan construction industry, through a comparison of material waste arising from pre-cast, ready-mixed and site-mixed concrete. Data were collected from 27 building construction projects and three concrete elements: slabs, beams, and columns, were considered to quantify construction waste. To compare the wastage due to pre-cast involvement with other types, three categories of building projects were used, including projects using pre-cast concrete elements, in situ concrete elements site mix, and in- situ concrete elements ready mix. The data for the study were collected from 27 multi-storey housing constructions projects, of which, seven projects used pre-cast construction and 20 projects used in situ construction. The wastage was compared between the basic materials used for three types of concrete elements are columns, beams and slabs. In this study, material wastage includes waste arising from manufacturing process at the factory level to the site level. For instance, material waste of pre-cast and ready-mixed concrete were quantified considering the waste arising from manufacturing process at factory level to usage at construction site. However, it was identified that waste during the transportation of ready-mix concrete and pre-cast elements is negligible. Further, waste of pre-cast elements at the site level was also noted as almost zero and, hence only the factory level waste was considered for the analysis. Techniques of material reconciliation were used to analyse the waste of ready-mix concrete and pre -cast elements at the site level, while work studies were used to quantify the waste of site-mixed concrete at the site level and wastage of ready-mix concrete and pre-cast concrete at the factory level. Pre-cast concrete waste The mean wastages of cement, sand and metal amounted to 5.34 per cent, 13.86 per cent and 7.62 per cent respectively showing the lower values compared with the material wastages in the other two situations (Table III). Further, it was shown that there is a noticeable difference in the generation of material waste between pre-casts and in situ (Figures 1 and 2). The main reason behind this may be due to the negligible wastes arisen during transportation and installation at the site. The pre-cast concrete elements transported to the site were stored unit wise by during transportation had been minimized and identified as zero. Since pre-cast elements were supplied according to the required length, waste arising during installation of elements was at a minimum level and waste occurring due to over ordering of materials was also eliminated. Further, the pre-cast elements were produced at factories under proper supervision using steel moulds which can be formed of different sizes. Therefor e, the wastage of materials during manufacturing also reduced to a considerable amount. Site-mixed concrete waste In site-mix concrete, the mean wastages of cement, sand and metal amounted to 14.39 per cent, 25.70 per cent and 16.11 per cent respectively showing higher values compared with the material wastages in other situations (Table III). This large quantity of wastage was identified due to the lack of supervision, inaccurate mixing methods, inappropriate type of equipment used, poor storage of materials and poor quality workmanship and this led to higher waste of materials in ways of excess cement being used to accelerate the curing process, excess concrete being used due to the breaking of form work, higher waste in transit and handling of metal and sand and excess concrete being used in uneven surfaces (e.g. attached concrete column). Ready-mixed concrete waste The mean wastages of cement, sand and metal amounted to 6.61 per cent, 22.31 per cent and 13.01 per cent respectively showing the higher values than material wastages of pre-cast concrete and lower values than material wastages of site-mixed concrete (Table II). Although there was lower wastage at the factory level, the overall wastage of ready-mixed concrete showed higher values. The main reason behind this is the excess ordering of materials, large quantity of concrete remains in pump car and pump pipe and poor quality workmanship at the site level such as breaking of formwork. Case studies in Hong Kong The questionnaire survey revealed that the construction activities were closely related to the amount of waste generated. Timber formwork is the major contributor to construction waste. The wet trades associated with finishing work such as screeding, plastering and tile laying are identified as the second major set of waste generation processes in the construction of buildings. Concrete work and masonry work are the next most significant groups. Site activities need to be emphasised in order to reduce building waste. In general, it was estimated that about 5-10 per cent of materials ended up as waste on building sites. Pecaform foundation formwork is made by laminating a layer of polyethylene to each side of a high tensile steel wire mesh. This combination creates a material that is both light and structurally strong, making it very easy to handle. It can be used for constructing ground beams, pile caps, footings, curved structures, ribbed and waffle slabs. The formwork is cut-to-size and bent to shape at a factory and arrives at site ready for installation. There is no need to strip the formwork after the concrete has cured. Very little waste is produced. A clean and neat site can be obtained in the foundation stage. Large panel formwork compared with traditional timber formwork, metal panel system formwork has several advantages. The use of large panel formwork can save time and labour in erecting, striking and re-erecting the formwork as the panel is handled as one unit. It can also produce a concrete surface much neater than conventional timber formwork and the surface essentially needs no additional applied finishes for levelling. So far, steel is the most popular material used for the formwork and the reusability of steel formwork can be as high as 100 times, and therefore much formwork waste is reduced. On-site waste audit also indicated that large panel formwork was effective in reducing concrete waste generated by loss in concreting and broken formwork, which usually accounts for about 30 per cent of the total concrete waste Prefabricated steel reinforcement system is tailor-made in plants where steel bars are mechanically cut, bent and fabricated. The completed systems are then transported to the sites for use. During the manufacturing process, the steel bars are cut and bent in a more systematic and accurate manner so that the wastage is kept to a minimum. Precast cladding is a new construction method for tiling works in the corridors of public housing projects in Hong Kong. The cladding panels are manufactured in the precast factory. The production processes are: place wall tiles onto the steel mould face down, pour lightweight concrete onto the back of the tiles, and demould after hardening. The tiles are thus cast integrally with the lightweight concrete and no traditional tile fixing by cement mortar or adhesive is required. At the construction site, the positions for holding brackets will be set out, and cladding panels levelled and fixed. The advantages of precast cladding panels are: reduced requirements on skilled labour with better end product quality, less wastage of raw materials and waste generation as wet trades on site such as plastering and tiling are eliminated, flexible time control as no setting and curing time are needed on site, and a cleaner and safer working environment. Machinery sprayed plaster was originally used in civil engineering applications. It now replaces the traditional cement mortar in some building projects. The major difference between the mechanised plaster and the traditional cement mortar is that the former is mixed and applied by means of a mechanised operation whilst the latter is applied and trowelled smooth by hand. The use of machinery sprayed plaster has the benefits of high productivity, low labour demand and less waste. Precast bathroom is an innovative feature in the construction of public housing. The wall, floor and ceiling of the bathroom are prefabricated with concrete as a whole unit and finished with tiles in the factory. PVC sleeves are also left in the structure for the future fixing of drainpipes. It is then transported to the site and installed into the final position of the building structure with the help of a crane. The only work required on site is to install the sanitary fittings, connect plumbing and electricity wiring to the building mains. Wet trades are avoided on site and this reduces material damages and wastage. Pre-cast external wall panels. Traditionally, external wall panels in high-rise residential buildings have been constructed in-situ with concrete panels finished with mosaic tiles. Pre-casting external wall panels enables panels to be pre-finished with the mosaic tiles attached together with windows and louvres installed. Building services provision can also be included. The finishes are fixed in the factory, production is not affected by the weather, a cleaner safer production environment results in stronger bonding and less tile wastage. Pre-fabricated fibre glass water tank. This type of pre-fabrication is an example of saving construction waste by materials substitution. All residential housing units of the New Harmony type include water storage on the roof of the building; the normal design solution is a cast in-situ concrete tank. An alternative to the construction of the cast-in-situ concrete water tank on the roof of the building is the adoption of a pre-fabricated fibre glass tank. Pre-fabricated internal wall panels e.g. dry wall partitions, and gypsum boards may be used to replace concrete or brick walls which are then finished by plastering in-situ. This has the potential to make significant savings in construction waste because a typical residential building would have some 452m2 of internal walls per floor and typically there would be 32 or 40 floors per building. The adoption of this form of construction has minimal impact on the design tasks because the pre-fabricate

Weve Only Just Begun: Translating Third Wave Theory Into Third Wave Activism :: Free Essays Online

We've Only Just Begun: Translating Third Wave Theory Into Third Wave Activism After graduating from college in 1999 with a degree in Women's and Gender Studies, I was looking forward to beginning my new job as an abortion counselor at the local Planned Parenthood clinic. I envisioned working in a strong feminist community committed to a women's right to control her reproduction. On my first day I was ordered to prepare the doctor's scrubs and get his coffee while I observed him chastise women during the procedure for not using birth control. I was angry for having to accept and accommodate this man because he was the only doctor we could get to perform abortions (and according to Roe v. Wade, as I learned, abortions could only be done by doctors). I had studied reproductive rights and was excited and inspired by my Second Wave feminist professors' praises of Roe v. Wade and women's health clinics, but my present reality was not living up to their romantic historical vision. I had also studied Second Wave feminist theories of power, economics, and sexuality and it was this knowledge that allowed me to understand that my so-called glamorous feminist work at Planned Parenthood was not, in fact, expressing feminist principles. I cultivated a desire to use these personal experiences break the silence in the feminist community about these discrepancies and challenge the impervious reputation of Roe v. Wade and abortion providers. I sought to involve myself in organizations working to allow midwives to perform abortions, which would give women more options when it came to choosing a provider. That was also when I came to understand and be a part of third wave feminism. Feminism's first wave is usually seen as having begun with the Seneca Falls Convention of 1948 and ending with securing the right to vote in 1920 and the second wave categorizes the resurgence of women's activism beginning in the late 1960s and ending (or at least ebbing) with the defeat of the Equal Rights Amendment and the Reagan-Bush era. Third wave feminism purports to encompass the young women born in the 1960s and 70s who feel their personal experience of their history set them apart from older women. Barbara Findlen in the introduction to Listen Up: Voices from the Next Generation of Feminism states, "I strongly believe that the experiences that led me to identify as a feminist were significantly different from those that inspired the previous generation" (xi).

Rip Van Winkle and the American Dream Essay -- Rip Van Winkle Essays

In Rip Van Winkle, Irving shows his doubts in the American Identity and the American dream. After the Revolutionary war, America was trying to develop its own course. They were free to govern their own course of development; however, some of them had an air of uncertainties on their own identity in this new country. Irving was born among this generation in the newly created United States of America, and also felt uncertainty about the American identity. Irving might be the writer that is the least positive about being an American. The main reason for this uncertainty is the new born American has no history and tradition while the Europe has a great one accumulated for thousands of years. Therefore, in order to solve this problem, Irving borrows an old European tale to make it take place in America. This tale related to the Dutch colonists haunts the kaatskill mountains. In order to highlight the American identity, Irving praises the â€Å"majestic† mountains which Europe lacks . He describes the mountains that â€Å"their summits†¦will glow and light up like a crown of glory† Nevertheless, the use of these ancient explorers into Rip Van Winkle only to show that although American has formed its own identity, no one can cut its connection with Europe. No wonder when America was still under tyranny of the British rule, some people still cannot cut the blood relationship with Europe. Therefore, the American identity is blurred by their relationship with Europe since then. Rip doesn’t cha...

Advantages and Disadvantages of Distance Learning Essay

Technology is advancing at alarming rates. In order to keep up with this ever growing field new means of education must be implemented. Distance Learning may very well be the best way to reach mass amounts of people rapidly. The advantages of Distance Learning are clear. The results are rapid and affect a broad community of people. Particularly with the field of technology, these qualities are necessary when examining way to teach those eager to learn. However, along with the advantages come the disadvantages. The purpose of this website is to outline a few of the advantages and disadvantages of distance learning, paying special attention to the field of technology. Cost: The cost of distance learning may eventually be significantly less than that of education as we know it today. Classrooms require books, binders, pens, transportation, and the actual expense of rent. Distance learning may one day rule out al of these expenses. Books may be available online, notes very easily could be taken using any word processor, and rent is eliminated as both students and professors could logon from the convenience of their own homes. Outreach: The greatest advantage of Distance Learning is its ability to reach many users’ that would otherwise have no way of taking classes. A grandmother may be too embarrassed to go to the local community college and sit amongst 18 year olds fresh out of high school. Distance Learning eliminates the need to feel judged by classmates. This may also help students who have physical or mental disabilities and wish to be home schooled. Another example of the broad outreach Distance Learning accounts for is the person that works 9-5 and has a family to provide for. This person may not have the time to travel to class, or the money to afford a baby-sitter. Distance Learning allows those with difficult schedules to learn on thier own time. Interaction: A major disadvantage of Distance Learning is the lack of interaction between teacher and student. Even when a lesson is taught live on the internet, the instructor misses cues, such as confused faces, that can only be seen live. The instructor cannot yell at a student for passing notes, or talking to their friend. Distance Learning may not be for everyone. Those who do not have a strong desire to really learn the material may easily be distracted. Already on the internet, they may be online talking to friends, or playing online pool. When a student needs extra help it may be hard for the professor to guide them without actually being there to walk them through every step of the way. Cheating: When a class is given online, cheating may be very hard to detect. It is very easy to cheat on exams that are given online, in the privacy of one’s home. Conceivable a student could receive an A in a course that another student took for them. Even at SUNY Albany, there have been cases of student cheating on online quizzes and Web CT submissions. Before Distance Learning is implemented on any large scale, this issue must be further examined. Written by Sara Volkell References Used Deakin, Michelle Bates. 2001.

Advantages And Disadvantages Of Online Education Kateri White Online University Century City, California Getting an online education has become a very popular technique these days. Whether you are looking for a high school diploma or a graduate degree or some specialized certification to supplement your existing knowledge, it is very convenient to obtain these without having to take time off from your schedule to attend a regular educational institution. There are many advantages associated with online study. Some are given below: †¢ Unlike traditional learning, distance learning can offer you greater flexibility, as you don’t have to waste time- and money- commuting to the campus and you can choose a program that truly suits your interests or professional needs, because you are not confined to the classes that are offered locally. †¢ Another advantage to distance learning is the fact that you can continue to work, because you don’t have to worry about fitting your classes around your job schedule. †¢ Online programs often cost less than their traditional counterparts, so you can save money on tuition, if you pursue your degree through an online university. †¢ Online study is also a great option for those students with physical handicaps, which may prevent them from traveling to a traditional campus. Likewise, if you are shy, or perhaps even language-challenged, participating in an online course may be the perfect alternative to a live class. There are some major advantages to online education, including the ability to set your own study time. You may be looking for a promotion or career change that requires additional training or you may simply be ready to learn something new. But with today’s busy lifestyle, there’s little time to devote to regularly scheduled class time. That’s where online education can be a great asset for a motivated person. Although there are many advantages of an online education, there are also some disadvantages. The fact that you are working on your own could very well be one of the major disadvantages of taking online educational classes. Another major disadvantage is the lack of interaction. You aren’t in a classroom and don’t have the opportunity to hear questions and discussion from other students. This isn’t always an issue, depending on the subject of the online education course you are taking, but it could be an important factor in deciding whether an online education is the best option when seeking out opportunities for learning new skills or gaining new training. But above all the disadvantages the online education is gaining more esteem than traditional education.
