Wireless Security And Vulnerability In The Wireless Network
Vulnerability in the Wireless Network Rafael Reccy Seminole State College Abstract Wi-Fi can be found anywhere in this day in age, you can walk into almost any establishment and youââ¬â¢ll be sure to find their Wi-Fi, accessible from anywhere within their spaces. Each data packet being transmitted through the air, whether containing private, sensitive or insensitive information, is available for an attacker to capture. To fight against this, there have been some standards that have come out through the years to guard and protect data, such as WPA. All standards have been created to replace the preceding one due to vulnerabilities found in the engineering of them. Still to this day, not every standard is fully secure, attackers still findâ⬠¦show more contentâ⬠¦Although, there is one of the vulnerabilities that is pretty much impossible to guard against, DoS like Molta points out, ââ¬Å"Other problems are looming, the most pernicious of which are DoS (denial of service) attacks. While DoS is a fact of life on all networks, its worse on wireless networ ks because not only do you need to guard against attacks at Layer 2 and above, youre also extremely vulnerable to physical-layer attacks to the mediumâ⬠(Molta, 2002, p. 18). In this essay, some vulnerabilities will be looked at that can affect Wi-Fi home users as well as businesses that implement wireless networks because both types of networks can be affected by the same types of intrusion or disruption attacks. Even though this paper is about vulnerabilities, it is important to point out that wi-fi networks can still be operated safely with a high level of security in place. Wireless networks are considered vulnerable when an incident occurs that exploits the capability to perform the desired requirement of maintaining performance and concealment of data. Most vulnerabilities happen because of the science behind a wireless network, the fact that it uses air as a medium makes it harder to protects because the environment of air is not stable and when it comes to delivering sacred information you must be onShow MoreRelatedThe Cyber Security Vulnerabilities Faced By Different Networks913 Words à |à 4 Pagesdifferent cyber security vulnerabilities faced by different network.

áriticism of literature an Example of the Topic Literature Essays by
à ¡riticism of literature On page seven of the book A Little Literature, by Sylvan Barnet, William Burton, and William E. Cain, it states when you write about a work, you will want to do much more than say, I really like this story, or This poem bored me. It is true that such an approach is too simple, lacking in depth, and will not really benefit anybody very much. There is, instead, a proper way to go about critiquing literature that involves the use of established methods. The result of using these methods will be a proper literary review of the work that will enable anybody that has not read the work to get a sense of its substance, style, overall quality, the person of the author, and its importance both as a singular work of literature, and also as compared to other writings. Need essay sample on "riticism of literature" topic? We will write a custom essay sample specifically for you Proceed Whenever you set out to critique literature, it is important to do more than merely state your final opinion of the work. Instead one should analyze and interpret the writing, and make assessments about such things as the meaning, impact, and effectiveness of the parts, themes, characters, scenes, imagery, content flow, and conflict resolutions. The main elements and ideas of the work should be identified, and particular lines and phrases of the text should be cited as examples to be examined. You don't want to give more that the shortest summary of the plot, but the focus should be rather on specific scenes, characters, and themes. These should each be identified with an adequate but brief description. Their relative importance should be recognized. The interpretations and assessments of these specific elements should be clear and pointed. When it is necessary to make personal expressions of taste, or to describe the impact that some element in the writing had on one personally, the se comments should also include as much supporting information as possible. These methods will make it easier to remain objective or, in a way, factual in your analysis of the writing, and to avoid generalities and the kinds of subjective opinions that the authors Barnet, Burton, and Cain counsel against. It is proper also to follow established forms when writing such a critique. It is customary to use the present tense when discussing a story or its contents. One should make mention of the author by his or her last name in a review essay, and care should be taken as always to use correct spelling and punctuation, to reference all quotes and citations properly, and to format the critique as would any standard essay, with an introduction, a body of discussion, and a suitable summary and concluding statement. A good review does not need to be lengthy; a few pages should be sufficient for most works under consideration. It is appropriate to speculate about the thoughts, the background, and the motivations of the author. In literature there are frequently hidden themes and underlying lessons that the author is trying to convey. These are often the result of deeply-held views or biases, perhaps religious or political in nature. Other convictions or passions may be born of dramatic life experiences, of an unusual upbringing, education, or from personal challenges and tragedies. These dynamics, personal to the author, often infuse literary works with ideas in ways that are important, and so an understanding of these issues can help one to better understand the works of a particular writer. For this reason a discussion of these qualities in the review can be useful in helping others to understand the work better. Another way to understand a work of literature is to compare and contrast the work with other literary writings. This is done by drawing from the elements of the two works some ideas, themes, scenes, plots, characters, descriptions, usages of imagery, etc., that are either similar or different in their natures. These similarities and differences should be clearly shown, and the various results can be compiled in a way that demonstrates the overall relationship between the two works. If a particular work is thought to have influenced the other in some way, this should be discussed, or if two or more works are important representations of a certain genre of literature, their elements can be considered together in this respect. And it is not at all improper to compare them qualitatively, and to judge the better of the two works and to state in summary why the one work is thought to be more effectively written, more entertaining, thought-provoking etc. When writing about literature, simple statements of opinion are often the least helpful. Literature is rich and varied in its nature and character, and any critique or review of literature should be undertaken in a way that reflects this. Any work of literature contains key ideas, concepts, main characters or events, something of a plot, and a relative ability to influence the reader. The writing might also compare and contrast usefully to other works, and might somehow also give us a view of the soul of the writer. A consideration of all these elements, organized properly, is the substance and structure of a good review.

Different Views on Eileen Changââ¬â¢s Early Fiction from the 1940s to the Present essayEssay Writing Service
Different Views on Eileen Changââ¬â¢s Early Fiction from the 1940s to the Present essayEssay Writing Service Different Views on Eileen Changââ¬â¢s Early Fiction from the 1940s to the Present essay Different Views on Eileen Changââ¬â¢s Early Fiction from the 1940s to the Present essayEileen Chang is the writer, whose works were neglected in China because of the suppression of her literary works by the Communist regime. She remained virtually unknown in China for decades, while her works has gained the public and criticsââ¬â¢ approval at the international level. Her works became renowned and popular in many countries of the world.However, the question that begs is whether her works were dangerous for the ruling regime in China that forced it to ignore her books and her contribution to the modern Chinese literature or probably she just became the victim of the undemocratic, repressive regime that fears all ideas, which are different from those promoted by the regime. In fact, the originality of her works and the writerââ¬â¢s focus on the position of woman and her role in China, which was quite different from Communist ideals, but close to the real life. Eileen Chang has uncovered the role of women in China through her major works, such as The Golden Cangue and Love in a Fallen City, which are a quintessence of historical awareness and moral judgments about women in China.According to the feudal ideology, female had no independent personality in ancient China, and this traditionalfeudalideologyevenaffectthenewgenerationwomenaswell. EileenChanghad a distinctiveunderstandingon female thatdifferentfromotherauthors. She paid a lotofattentiontowomenanddescribedmanytragic female characterswithherunique perception. Female characters play the main part in many of Eileen Changââ¬â¢s works, including The Golden Cangue and Love in a Fallen City.At the same time, the author does not just tell a conventional story of a woman but also uncovers the historical context and the role of woman in Chinese society. She uncovers the real life of women and the emerging conflict between their strife for self-realization and changing their social role, on the one hand, an d the dominant, biased and prejudiced view on the role of women in Chinese society of that time. In such a way, she uncovers the intrinsic conflict between attempts of women to become more independent and equal to men and the male-dominated ideology and culture of the 20th century China. At this point, a sort of marriage obsession determines, to a significant extent, actions and life of the main character of Love in the Fallen City, while the main character of The Golden Cangue has failed to lead the life she wanted to and marry the man, whom she really loved, and became the loser, whose failure in her life extrapolated on her own children.Love in a Fallen Cityà describes the lives of women located between the modern and the traditional, trapped by limited options and social constraints, and forced to find a balance between respectability and freedom (Yee, 2012). The main character of the short story views the marriage as her lifeââ¬â¢s priority but she confronts numerous chall enges on her way to the attainment of this goal. However, the problem is that her dream of marriage is rather the result of the impact of gender-related biases and dominant social views on gender roles. She believes that marriage is essential for her as for a woman. She turns out to be vulnerable to the impact of social norms and belief that a woman should be a good wife and mother but, eventually, her personality comes into conflict with the dominant social view on the role of women. As a result, her pursuit of personal happiness and independent life, on the one hand, and the burden of social biases and stereotypes, on the other, come into clashes and make her life virtually unbearable.Love in a Fallen Cityà portrays BaiLiusu and Fan Liuyuan as selfish people thus their so called love is just to get what they need instead of chasing love. ââ¬Å"He was just a selfish man, and she was just a selfish womanâ⬠(Chang, p. 277), they tried to exchange what they really need with th eir ââ¬Å"loveâ⬠.à In such a way, the main characters of the short story were selfish in their love and they pursued their own goals and did not love each other.At the same time, the strife of Bai for marriage becomes obvious in the episode, when Fan mentioned the verse in The Book of Songs: ââ¬Å"Life, death, separation- with thee there is happiness, thy hand in mine, we will grow old together.â⬠But Bai said ââ¬Å"Why not go ahead and just say, flat-out, that you donââ¬â¢t want to marry me, and leave it at that!â⬠(Chang, p. 268).Marriage was so important to her that made her lose the ability to love someone without counting the profit she can earn from the relationship. She would lose the trade with Fan because she misunderstood the rules. Fan repeated again and again that he needed her to understand him by saying ââ¬Å"I donââ¬â¢t understand myself- but I want you to understand me!â⬠(CP p. 263). In such a way, she wants to live the happy life and e njoy her life without any responsibilities and obligations but, on the other hand, she has to marry and the marriage bounds her freedom drastically. In such a situation, she cannot understand Fan Liuyuan, who looked for a different love and relationships with Bai. In fact, ââ¬Å"it turned out that what Liuyuan cared about is spiritual loveâ⬠(Chang, p. 264). She agreed since spiritual love leads to marriage, but she is just using Fan to reach her goals. In such a way, the main character of Love in a Fallen City challenges conventional norms and destroys the idealized image of a Chinese woman, who is a faithful and devoted wife, who adores her husband. Instead, Chang depicts a pragmatic, cold-blooded woman, whose reason is stronger than her feelings and, in this regard, she has features, which were traditionally attributed to men rather than women in China.The resolution of the story comes at the end andà it is the ending haunted by uncertainty and dark premonition.ââ¬Å"Hong Kongââ¬â¢s defeat had brought Liusiu victory. But in this unreasonable world, who can distinguish cause from effect? When theà huqinà wails on a night of ten thousand lamps, the bow slides back and forth, drawing forth a tale too desolate for words - oh! why go into it?â⬠(Chang, p.297). In such a way, the conflict between Baiââ¬â¢s personal identity and dominant cultural norms reveals the profound transformation that has started in Chinese society, as women came to the point, when they became aware of the necessity to change their role and stand on the equal ground compared to men.The Golden Cangue tells the story of a woman from a poorer family - she has worked in a shop selling sesame oil - who is married into a wealthy, traditional family, but to a cripple (Huang Keyton, 2011). Through her attempts to maintain her status and her prickly personality she alienates her in-laws as well as those of her own family who try to stay in contact. And then, after she has gained independence on the death of her husband, she takes out her bitterness and frustration on her own children (Sze, 2010). The main character of The Golden Cangue is quite different from the conventional female character traditionally depicted in Chinese literature. Instead, Eileen Chang focuses on the depiction of the female character, who wants to break through existing conventional social norms but fails and her failure to break down all those social norms that bound her and ruin all her life. In despair, she has nothing to do but to ruin the life of her own children. In such a way, the author shows how gender-related biases and stereotypes keep Chinese women within boundaries imposed on them by the male dominated cultural and social norms and which deprived women of their full freedom. The main character of the short story is virtually forced to marry a sick man because of his wealth. However, as she marries, she cannot take decisions and act in the way she likes and really wants. For example, she falls in love with her brother-in-law but she cannot break the existing social and cultural norms and start relationships with him or divorce her husband and marry his brother. Such an act would be absolutely unthinkable for a woman in China in that time. At this point, the main character of The Golden Cangue faces the similar conflict between her personal aspirations and desires and social norms and rules as does the main character of Love in a Fallen City. She wants to rebel against existing social norms but cannot dare to do it. As a result, she comes to the point, when she understands that her life was a sheer failure and the only way she finds out is to ruin the life of her children because probably she is so desperate that cannot afford their happiness and she is locked in her ââ¬Ëkingdomââ¬â¢ created respectively to norms of Chinese society but, under the impact of those norms, which made her unhappy, she becomes tyrants destroying the life of he r children. Eileen Chang didnââ¬â¢t portray too much about the personality of Chââ¬â¢i-chââ¬â¢iao, but paid much attention on the spirit, focusing on the characterââ¬â¢s inner world. In Chââ¬â¢i-chââ¬â¢iaoââ¬â¢s mind, her inner world was dominated by human desire, thus we can observe extreme changes of her personality during the domination. Under Eileen Changââ¬â¢s description of Chââ¬â¢i-chââ¬â¢iao, regardless of the ending and her fate, she already became the slave of money and the capture of human desire. We can see the overwhelming power desire has on Chââ¬â¢i-chââ¬â¢iao, regardless of her social class, causing a human tragedy in extreme circumstances when her goal is unattainable.Eileen Chang reaches her goals to show the position of women in Chinese society and their strife for changes using her literary works and vivid and challenging life stories of her main characters. At the same time, she also uses skillfully diverse stylistic devices t o convey her main points to the audience. In this regard, the rich imagery and profound exploration of human nature are distinct features of Eileen Changââ¬â¢s major works, such as The Golden Cangue and Love in a Fallen City. Chang attempts to explore the internal world of her main characters and show the audience how different the internal world of her main characters is compared to what the public can see. The main characters of The Golden Cangue and Love in a Fallen City live a normal, regular life of typical Chinese women. However, as the author uncovers their internal world, the audience learns that their seemingly perfect and happy life is illusory, while, in actuality, they suffer and their life is unbearable for them.The Golden Cangue and Love in a Fallen City transcend historical awareness and moral judgments (Zaifu, 2009). The main characters of her short stories confront the problem of the conflict between their internal desires and wants and social norms and rules. Th ey want to break free of social biases and norms, which though turn out to be too strong for them.There is a mix of traditional Chinese and Western influences in Changs style as well as in the situations of her characters (Zaifu, 2009). Her descriptions of objects and clothing and little details are realist but also convey classical imagery and symbols (Zaifu, 2009). The events covered in these novellas span considerable periods of time - many decades in some cases - and they are almost family sagas, tracing the life stories of individuals and their families (Yee, 2012). In some ways her canvases are quite limited, but Chang fits a real diversity of characters and events onto them (Yee, 2012). In such a way, the main characters of her stories uncover her vision of the role of women and changes that occur in Chinese society.Thus, Eileen Chang reveals profound changes in Chinese society that have changed the role of women.

See attachment - Essay Example In this case, the African Americans used their different ideologies, as power. They therefore, promoted their ideologies, which included their beliefs and values that helped them make sense of the world, in the midst of domineering ideologies of the European. They mainly were able to embrace their ideologies, when they resisted most of the ideologies of the colonial masters, which were imposed on them. The African-American slaves utilized their material culture as a source of their power, and independence, and used this to shape their lives according to their preferences. To counteract the ideological power of the African-American slaves, the planters too used ideology as a way of covering up their exploitations of the slaves and blinding the African-Americans on the evils of slavery. They therefore, did this through different attempts to gain control over the material culture of the slaves. Instead of the slaves using their material culture, the planters offered them ââ¬Å"nicerâ⠬ clothing, housing, and food. However, most of the slaves did not accept the material culture of their planters, but preferred their own. They therefore, used their own material culture as a source of their ââ¬Å"dominanceâ⬠and power (Ferguson 118-9). Therefore, by ââ¬Å"ideological powerâ⬠, Ferguson referred to the culture of the African-Americans, since they based on this to resist the exploitations and injustices of slavery. African-Americans were under slavery for many years, as the whites had more dominion over them. The whites were more developed, with an advanced culture and education, compared to Africans. Therefore, it was least expected that the African-Americans would get powerful to the extent of breaking free from slavery. The African-Americans had no powerful weapons to engage in a war with the whites, in pursuit of their liberation. African-Americans only had their culture at their disposal. Therefore, these used their distinct culture as a shield fro m most of the exploitations from their ââ¬Ëmasters.ââ¬â¢ The African-American culture was stronger than the American culture, since this combined both the indigenous African culture and some aspects of the American culture, which was acquired through the interaction of the blacks with the whites (Ferguson 58-9). Some archaeological examples of African-American ideological power in colonial America examined in Uncommon Ground. The ideological power of the African-American slaves mainly lay in their material culture. This form of ideological power helped African-Americans to resist the oppression of the white masters. This also served as a basis for resistance for the inequalities and exploitations by the white masters. This ideological power of the African-Americans mainly linked their social meanings with power. Therefore, the archaeological research by Ferguson is essential in tracing the distribution of material culture and establishing the different ways through which the a doption of these by the African-Americans played the role of resistance to the white oppression and exploitation. By refusing to embrace the material culture of the whites, the African-Americans wanted to maintain their cultural and social identity, thus avoiding assimilation by the American culture. There is different archaeological evidence provided by Ferguson that reveals the African-American ideological power during slavery. However, all these lay in the cultural aspects of the African-Am

Modern globalization Essay Example | Topics and Well Written Essays - 1500 words
Modern globalization - Essay Example One most important effect of globalization is power discourse. Globalization refers to the process that takes place around the globe and that creates remarkably significant effect on the position of power among the nations (Cavusgil, Knight and Riesenberger, 2013). This shows that the term globalization does not relate to any single concept that might be encapsulated within a definite frame at a defined point of time. It is a process with a long history. Although globalization is regarded as a recent phenomenon, several environmentalists, economists and scientists univocally claim that this process has its beginning in the distant past and it cannot be clearly predicted whether it has any definitive end. While most of the activities of the modern world are shaped under the effect of globalization, several activities are recognized as the ââ¬Ëbad effectsââ¬â¢ of this process (Sassen, 2000). After a prolonged period of time, scientists have seen signs of this process of globaliza tion to weaken in the current international economic and business scenario. These effects also cannot be determined as absolutely good or bad. It rather depends upon the way in which the term has been defined in a particular context and the level of impact that this phenomenon has cast on the performance of the sector or firm. Thus, in popular discourse, the term holds varied meanings. Hence, it is imperative to distinguish between the two types of concepts of globalization; one that is viewed as contemporary ideology of modern politics and the other that is related to as structural globalization. The current wave of globalization is the outcome of large scale interaction within dense networks of individuals and institutions around the world. International trade has increasingly become a function of global production of goods and services and their distribution (Chase-Dunn, Kawano and Brewer, 2008). Various arguments made by different economists, policy makers and environmentalists can be presented in this context. Some of these arguments support the positive impacts of globalization while others support the negative impacts of globalization. Arguments for and against globalization At present, the economic development of the global economy is highly dependent on the waves of globalization. With the beginning of the 21st century the world has moved on to a higher level of networking and interconnectivity. This is applied to all the aspects of society and economy. There has been structural reformation in the fields of technology and knowledge transfer has become more advanced (Hipsher, 2006). The fragmented dimensions of the economy in different parts of the globe of the globe get interconnected with smooth flow of technology and better networking. The different parts of the world are becoming more interconnected with one another and socially as well as economically. This structural reformation lays emphasis on the integration of diversities imbibed in the cultu re and practices of the different nations. On the other side of the coin, the process of globalization takes into account the diversities or differences in culture. Hence, it implies that this process leads to unification of the different ideas, cultures and practices among the nations. Under this process the world is considered as a single unit or economy that runs by following a uniform system. This leads to the formation of one single society. However, there are also certain drawbacks of the global integration.

Library System Essay Example for Free
Library System Essay This chapter deals with the review of Literatures and Studies. It also presents the synthesis of the review and its relevance to the present study. Related Literature AMA student Kariz Reinalyn B. Galano (et. al. Don Ricardo C. Lazaro, Rozmaigne Ann L. Sebastian, Kevin Patrick E. Viesca) (2012) cited in their approved thesis proposal at present ACLC has three hundred sixty five students enrolled. The institution is currently using a manual system in their Library and has weak security. Students can borrow books but need to return it within 5 school days. There is no proper monitoring on books being returned. There are no penalties imposed to the students as well. The only way the librarian will find out if there are still pending books not returned is during the end of semester at the inventory period. The librarian then will not sign the clearance of the students who failed to return the books. Another problem is the list of inventory of books. The students need to go and ask for the librarianââ¬â¢s assistance in order for them to search for the books. Karen Foss (2010), Library Director of the Catawba County Library System in Newton, North Carolina has expressed that it is difficult to find materials to help new public library managers cultivate their professional development. Most of the research and writings on library management have focused on academic libraries and only recently has there been more interest in the administration of public libraries. The skill and style of public library managers ââ¬â the directors, branch managers, and department and service managers who are leading these institutions ââ¬â strongly affects the culture of a public library. Library staff looks to these managers to help them navigate through the rapid changes that are occurring in public libraries as these changes in technology, roles, and user expectations strongly alter their daily routines of public service. Contemporary library managers need a wider array of skills and attributes than their earlier and more traditional counterparts and will need to seek continual professional development to remain effective as public libraries transition into the twenty-first century. These managers will also need to distinguish between management and leadership skills and learn to identify and mentor leaders within their staff who can assist in the transition. According to Alvin javelosa (2011) library is a collection of books, resources, and services, and the structure in which it is housed; it is organized for use and maintained by a public body, an institution, or a private individual. The term library has itself acquired a secondary meaning: a collection of useful material for common use, and in this sense is used in fields such as computer science, mathematics, statistics, electronics and biology. this study will help the library personnel or the librarian in monitoring the books accurately. Further, the use of cataloguing will be made easier through an advance system provided by this study. The librarian is encountering problems in doing transactions like borrowing books, checking the availability of books, returning and accessioning of books because all the transactions are being done manually. The process is time consuming. This proposed system will provide their library a computerized system making it more organized and easy to access. The advantage of this study is to make their current system more effective and efficient. This computerized library system is a transaction processing system (TPS) that will provide a convenient cataloguing, inventory, monitoring, accessioning, borrowing, returning, security and retrieving of records. html) According to Mohd Fairuz Anwar Bin Mahadi (2005), The Library management system will store all the books and members information that consist book number, book title, author name and racks to the system database. The system also provides search function to help students find the book by number of book. Search functions will search through the books database to look for the book and view where the book is situated. For the administrator user, only librarians have access to view or edit data from the system databases. Administrator user will handle administrative functions such create new LMS user account and decide the number of days allowed for the borrowed books. User needs to enter correct password and user id before user can access this function. From here, user can add, delete or update the book and borrower database. (http://library. utem. edu. my/index2. php? option=com_docmantask=doc_viewgid=3761Itemid=208) According to Donna M. Salinas (2010) Library is the best place in the school where the students review and study. It is the place where students study so our group aims to improve the manual operation of the library system. We thought of something that makes the time of students and library personnel decreases for searching and borrowing of books. (http://www. scribd. com/doc/56632694/library-system) Related Studies: According to Shelagh (2001) Fisher library management system is becoming marginalized in the context of ICT developments currently taking place within the library sector because suppliers have failed to keep up with such developments, or have been more concerned with keeping up with the changes in the core functions. The aim of this research, therefore, was to determine the feasibility of developing and disseminating a model system specification which could be used to assist and guide libraries in the procurement of library management systems. The premise was that if a core set of requirements for library management systems, as articulated by purchasing libraries, could be identified, it followed that it would be feasible to develop a model specification or ââ¬Ëtoolkitââ¬â¢ on which procuring libraries could draw. Identification of a potential core set of requirements could be identified primarily by undertaking analyses ofà specifications produced by libraries for the tendering process in acquiring a library management system. Thus forty-one specifications were collected from libraries which had recently acquired a library management system, and these were subjected to various levels of analysis. The results are reported in Section 4. Secondly, it was decided that as library system suppliers were in receipt of large numbers of specifications produced by procuring library authorities they were in a strong position to comment on the feasibility, and desirability, of developing a model specification. Thus, a survey of UK system suppliers was undertaken to determine the collective view of suppliers on the role, content, quality and usefulness of the specification as a procurement tool. The results of the survey are reported in Section 5. A detailed account of the methods used in this Study is provided in Section 3. The next section (Section 2) provides a review of the literature on the role and content of specifications, and identifies weaknesses in approaches to producing specifications for the purchase of library systems. (et. al. Rachel Delbridge, Sian Lambert) (http://www. cerlim. ac. uk/projects/harmonise/harmonise. pdf) According to Veronica Adamson (2008) Changes in society and technology are impacting significantly on UK HE libraries and consequently on their management systems. Demographic changes, political and economic drivers are affecting university services and funding structures, and a ââ¬Ënew realismââ¬â¢ of pragmatic economic and business considerations presides. (JISC SCONUL LMS Study Report, March 2008) Library management systems have developed in response to technical advances and user requirements, mainly in developing electronic interfaces, refining standards and access protocols, purchasing and acquisition processes and cataloguing systems. Increasing globalization of goods, services and communities means that technical platforms are now developed on an international basis and implemented for a worldwide network of users and contributors. A new market for library services and information provision has emerged, with Google and Amazon as a de facto paradigm and metaphor for discovery and delivery. Perceptions of the role and function of the university library are changing, developing and often conflicting, particularly in relation to the provision for collection and circulation, resource discovery, ownership and control, personalizationà and seamless access to resources. Enhancing usability and accessibility for an increasingly diverse user community is of increasing importance for libraries. Todayââ¬â¢s library users expect speed and immediacy of information discovery, one-stop access to aggregated services, user-generated open content, and personalized, workflow-related delivery to the desktop. (et. al. Paul Bacsich, Ken Chad, David Kay, Jane Plenderleith) (http://www. jisc. ac. uk/media/documents/programmes/resourcediscovery/lmsstudy. pdf) According to Herrera C Rocio (1987) the work habits of users in any activity requiring information, the importance they attach to obtaining it and the facilities at their disposal, their knowledge of these facilities, their assessment of their value and the possibility of their obtaining what they are looking for are the factors that affect user behaviour in the quest for information. The behaviour of the users of university libraries specifically is affected, in addition to the above factors, by others directly related to the university environment, such as teaching methods and the type of education provided. The countrys education system is a teaching-learning process largly consisting in an essentially repetitive pattern in which the student consumes and reproduces the concepts transmitted by the teacher. This model is mainly based on the university lecture system, in which the teacher simply gives a course of study and provides the pupil with a brief bibliography consisting basically of texts. The result has been that education has not become a critical and creative process and library resources have accordingly been under-utilized. As regards the response to the information services provided by university libraries, it can be said that research workers do not use the services properly since the role of the library as an agent for the transfer of information has been disregarded in the research process, this type of user tending to acquire information through informal channels of communication, such as personal contacts with other colleagues. In its turn, the library has neglected its task as a constituent part of the research enterprise, forgetting that one of the priorities of the university, in addition to its teaching role, is that of research, which is the source of much knowledge of benefit not only to the university but also to the community in general. The university library should pay special attention to ascertaining not only the specific information needs of each type of user but also user behaviour patterns in the information retrieval process, in order that these needs may be met and the factors responsible for the non-use of the library restricted to a minimum. This will be achieved through an appropriate methodology for conducting user studies, which will then provide guidelines for the organization of user training or instruction courses aimed at the various groups. These courses will influence the future response of users to information services. Since user behaviour in the information retrieval process determines the level of library-user interaction, continual monitoring by the librarian of changes in that behaviour is necessary. These changes are dependent not only on information needs but also on the possible impact of the introduction of new services. This shows that, over and above the matter of training in the use of library resources, user behaviour presents a number of special features, largely reflecting the fact that the information needs of those concerned are not well defined and that their request for information are consequently vague and very general. It follows that library staff should bear in mind their active role in promoting and publicizing their services and resources since, despite the continual emphasis placed on the role of information in development, it has been shown that users tend to dispense with non-essential information, the usual practice being to rely on memory, to evade the problem or to solve it with vague or incomplete information. However, it should not be overlooked that there is another group of users who consult libraries actively and effectively in order to satisfy their information needs; although accessibility influences the use that they make of resources, the most important thing for this group is their confidence and faith in the information system. (c Loreto M. Libia and Rua R. Ivan) (http://www. unesco. org/webworld/ramp/html/r8722e/r8722e0l. htm) According Neelakdan,B (2010) a sincere attempt has been made towards finding out ways and means for automating activities in the School of Chemistry Library. The objective of this study is to use the Koha Open Source software system for the automation of the major dayà toà day activities of the various section of the School of Chemistry Library, which is tiresome and cumbersome. After the investigation, the researcher has found that Koha Software is more suitable for the library Automation. This project had the basic objective of designing a bibliographic database for the School of Chemistry library, with which the automation of circulation routines is carried out. From this point of view it may be concluded that Koha is a useful package for the creation of a database and for information retrieval. This set of Manuals for the automation of circulation section is tested with the database created from the collection of chemistry department library. A sample database for a few thousand works and a database of the users/borrowers are created. With that test sample the Manuals for each function of the circulation section is tested with the available computer system. Koha is an integrated software system with all the required models for small to very large libraries. It is found that this automation projects will serve as a model for any library. (http://www. ipublishing. co. in/jarvol1no12010/EIJAER1014. pdf) According to Dio P. Doble (2011) A college strengthens its educational level through the advancement of its library. The Botolan Community College Computerized Library System aimed to enhance the procedures of the library, from manually operated to a computerized system. This proposalââ¬â¢s purpose was to ease the transactions in the library, i,e. , leading of books, storing of books, search engine for books, manage members of the library and secure the library system. The librarian and the library users still use the manual way of transacting of borrowing and returning of books. The librarian use log books in listing the books. They use library cards and card catalogues in searching for reading and reference materials. (http://www. scribd. com/doc/99431218/Computerized-Library-System)

american Essay -- essays research papers
The 21st Century American The traits of the typical American have changed drastically throughout the years. Americans have become different in many ways from when they officially became independent in 1776 to the present time in 2001. America is strong, powerful, and influential. Americans exemplify positive values, selflessness, hospitality, and the American way of life. Our values often differ from values of other countries due to cultural contrasts such as with religious, racial, and education issues. We give much more freedom than many other countries do to those of different races and religions. Also, we hold education in a much higher regard than other countries. It is these differences that sometimes make our country seem more appealing to those of foreign lands. Our common American values bind us together as one unit. Americans are often stereotyped as living a fast paced working environment in which they eat fast food and drive fast cars. Some of the aspects of American culture which are typical are: pizza, jeans, sunglasses, baseball hats, name brand clothing, tattoos, cellular phones, bagels, and bottled water. The Popular culture that has developed in America has had a major influence on cultures in countries all over the world. Cell phones have become popular in Europe; name brand clothing has taken off in Asia, and McDonaldââ¬â¢s restaurants exist all over the globe. While the American can be looked at as a singular stereotypical entity, it is important to realize the many differences that exist between Americans living in different regions of the country. When people who have lived in America all their lives travel to a different part of the country, they are often just as amazed at the differences in culture as people are who come to America from foreign countries. For Instance, a woman who is a New England native that travels south to North Carolina for the first time will be shocked at the cultural differences she encounters. The New Englander will discover that the natives of North Carolina speak different, eat differently, and even act differently. She discovers what is referred to as ââ¬ËSouthern hospitalityââ¬â¢ when she interacts with people who exhibit a sense of kindness and manners far beyond that of which she is accustomed. On the menu at restaurants she will see items she is unfamiliar with, such as: grits, pigs feet, cheesy w esterns, an... ... his luggage he has a conversation with a man who introduces himself and for some strange reason takes his hand and shakes it. When faced with the decision of what to eat he finds it difficult to decide because of the many different types of restaurants in America. He has trouble deciding whether to eat at a fast food place, southern restaurant, western restaurant, Chinese, Italian, Mexican, Indian, or French cuisine. After making his decision he is again amazed that rice is nowhere to be found on the menu. Despite the differences in culture between America and China he realizes he is in a great nation that is full of opportunity. America is a just and free nation. Its greatness is admired by the entire world. Many immigrants come to America to find a better life and for others it is merely a dream. Those who do become citizens are welcomed into the greatest most powerful nation in the world. American is made up of a cornucopia of cultures from around the world. The fact that Americans from different regions are different does not obscure our identity as a nation. Instead, these differences are what unite us as one nation, under God, Indivisible, for liberty, and justice for all. american Essay -- essays research papers The 21st Century American The traits of the typical American have changed drastically throughout the years.

Computerized Library System Essay
Introduction A library is a place in which literary and artistic materials such as books, periodicals, newspapers, pamphlets, prints, records, and tapes, are kept for reading, reference or lending. A collection of such materials, especially when systematically arranged; a room of private home for such collection. At first glance, your library is a bunch of books with a librarian to check them out to you, and back in when you return them. Your librarian insures (of tries to, as money permits) your library is well stocked with current titles. These current titles include, in addition toà books, videos, tapes and CDs, magazines, encyclopedia, genealogical research stuff and more. The librarian also has to keep the building neat and in good repair and also these things only shows a few of the things which make up your library. Early modern libraries ââ¬â Johannes Gutenbergââ¬â¢s movable type innovation in the 15th century revolutionized bookmaking. From the 15th century in central and northern Italy, the assiduously assembled libraries of humanists and their enlightened patrons provided a nucleus around which an ââ¬Å"academyâ⬠of scholars congregated in each Italian city of consequence. Cosimo de Medici in Florence established his own collection, which formed the basis of the Laurentian Library. [20] In Rome, the papal collections were brought together by Pope Nicholas V, in separate Greek and Latin libraries, and housed by Pope Sixtus IV, who consigned the Bibliotheca Apostolica Vaticana to the care of his librarian, the humanist Bartolomeo Platina in February 1475. [21] In the 16th century Sixtus V bisected Bramanteââ¬â¢s Cortile del Belvedere with a cross-wing to house the Apostolic Library in suitable magnificence. Background of the Study Objectives of the Study: The purpose of this study is to expand the knowledge about the library system. We developed a new library system for easier transactions of the library and a hassle-free job. General Objective ââ¬â This study aims to design and develop library system for faster processing and hassle-free for borrowing of books of the students. Specific Objectives ââ¬â In order to meet the requirements of the general objective, the following specific objectives were formulated: 1. To define possible problems in a library. 2. To analyze how the traditional library system works. 3. To prove that the proposed system is technically and operationally feasible for implementation. Statement of the Problems 1. When most users do not return books at the exact deadline. 2. When most people make noise in the library. 3. Not following a rule that one shouldnââ¬â¢t bring food or drinks. 4. When some of the books cannot be easily found due to unorganized compilation of it. 5. Sometimes itââ¬â¢s hard for the librarian to use the traditional library system so we must prefer a new system for the library. Scope and Limitation Scope ââ¬â The primary objective is to develop a computerized library system that can help others in listing and manipulating the transaction throughout the borrowing and returning process of the book. The proposed system will provide an innovation for the current traditional system that others use. Limitation ââ¬â Although this research was carefully prepared, I am still aware of its limitations and shortcomings. First, because of the limit, this research was only conducted only a small size of population like the also students in the entire campus. Therefore, to generalize the results for larger groups, the study should have involved more participants at different levels. Second, the population of the experimental group is small, only thirty-five students and might not represent the majority of the students of the intermediate level. Third, since the questionnaire designed to measure the studentsââ¬â¢ attitude towards the use of communication strategies might give useful information about the impacts of communicative strategies; it seems not to provide enough evidence of the studentsââ¬â¢ actual behaving to communication skills in their speaking performance. Significance of the Study The study is aimed at enhancing the existing manual processing system that will make operations more organized, efficient and convenient to use. It is also used to track items owned, orders made, bills paid, and patrons who have borrowed. A library system is usually comprises a relational database, software to interact with that database, and two graphical user interfaces (one for patrons, one for staff). Most library systems separate software functions into discrete programs called modules, each of them integrated with a unified interface. Definition of Terms Database ââ¬â An organized body of related information Library ââ¬â A library is a collection of sources, resources, and services, and the structure in which it is housed; it is organized for use and maintained by a public body, an institution, or a private individual. In the more traditional sense, a library is a collection of books. It can mean the collection itself, the building or room that houses such a collection, or both. The term ââ¬Å"libraryâ⬠has itself acquired a secondary meaning: ââ¬Å"a collection of useful material for common use. â⬠This sense is used in fields such as computer science, mathematics, statistics, electronics and biology. It can also be used by publishers in naming series of related books, e. g. The Library of Anglo-Catholic Theology. Libraries most often provide a place of silence for studying. Librarian ââ¬â A librarian a professional library worker. In most cases, a librarian holds at least a Masterââ¬â¢s degree in Library Science from an ALA-accredited library school. He or she may have additional degrees. System ââ¬â A system is a collection of elements or components that are organized for a common purpose. The word sometimes describes the organization or plan itself (and is similar in meaning to method, as in ââ¬Å"I have my own little systemâ⬠) and sometimes describes the parts in the system (as in ââ¬Å"computer systemâ⬠). Data Flow Diagram ââ¬â A data flow diagram (DFD) is a graphical representation of the ââ¬Å"flowâ⬠of data through an information system. DFDs can also be used for the visualization of data processing (structured design). Flowchart ââ¬â A flowchart is a type of diagram that represents an algorithm or process, showing the steps as boxes of various kinds, and their order by connecting these with arrows. This diagrammatic representation can give a step-by-step solution to a given problem. Process operations are represented in these boxes, and arrows connecting them represent flow of control. Data flows are not typically represented in a flowchart, in contrast with data flow diagrams; rather, they are implied by the sequencing of operations. Flowcharts are used in analyzing, designing, documenting or managing a process or program in various fields. Chapter II Review of Related Literature Local Studies The Silliman University Main Library System began its services with only two bookcases and one small room in Silliman Hall. From this humble beginning, the library collection grew steadily. Today, with its present magnificent edifice, some observers have been heard to remark that it could well be among the best in Southeast Asia. The library aims to equip itself with updated materials, facilities, and equipment in support of the Universityââ¬â¢s quest for excellence in all its academic programs. The Library now holds more than 100,000 volumes of books on various subjects. It subscribes to local and foreign serials and maintains special pamphlet collections, namely, Filipiniana, Southeast Asia, and United Nations. It also has a Sillimaniana collection which is housed in an air-conditioned room located at the southern portion of the first floor of the library building. Materials in the collection include the Weekly Sillimanian, Sillimanian Magazine, Portal, Faculty and Staff publications, and others. Various plaques and trophies awarded to the University, as well as, portraits of present and past presidents of Silliman University are also on display. In terms of facilities, the Library provides individual study carrels for its users. In addition, there are also faculty study rooms for the use of faculty/staff members who are undertaking research work for the University, or writing their theses or dissertations. These faculty rooms are available upon application at the University Librarianââ¬â¢s Office. For group discussions, there are two discussion rooms available at the second floor of the library building, on a first come, first served basis. Foreign Studies Itââ¬â¢s Time for a National Digital-Library System By David H. Rothman William F. Buckley Jr. , once denounced the growing popularity of CD-ROMââ¬â¢s in student research. Shouldnââ¬â¢t young people learn from real books? Tom Peters, a veteran public-library advocate, is coordinator of LibraryCity. org, a new online ad hoc group that will seek to deal with these matters, especially whether the national digital library should be mainly for the intellectual elite or also serve the rest of society in many directly practical ways. Peters is a former director of the Center for Library Initiatives of the Committee on Institutional Cooperation, a consortium of the Big Ten universities plus the University of Chicago. I am co-founder of LibraryCity, and like Peters, I hope that Darnton and others will agree with the idea of a genuine public library rich in content and services for the nonelite as well as the elite. Harvardââ¬â¢s Berkman Center for Internet & Society is sponsoring the March workshop to kick off its research and planning initiative for a ââ¬Å"Digital Public Library of America. â⬠With funds from the Alfred P. Sloan Foundation, the project will bring together a diverse group of stakeholders to define the scope, architecture, costs, and administration of such a library. LibraryCityââ¬â¢s intent is to augment the Harvard effort, rather than replace it, by offering a grass-roots perspective in depth. Chapter III Methodology and System Software Design Nowadays, in a highly technological society, human productivity is made more efficient through the development of electronic gadgets. Now, with the advent of such modernization in education, one way to globalize the process of research is to realize that technology is advancing at an incredibly fast pace. Computers are not confined to being used for entertainment but its role in education is also vast. In addition, it is a place in which we get information in any format and from many sources. The librarian has to keep the room neat so that it is conducive for learning. The librarian is also the person who is liable for monitoring all the books that are borrowed and returned by the borrowers. The aim of the study is to investigate the effectiveness of the computerized library system in order to support the continuous learning in various pedagogical settings. To achieve this primary goal, the study should consider the three objectives. First is to compare the existing library system from the traditional system and identify the pros and cons in both public and private learning institutions. Second is to compare and contrast the various schools or universities that successfully managed the computerized approach as new library system. Third is to identify the weaknesses and potential threats to make a recommendation on how to strengthen the computerized library system. Respondents of the Study We have asked 25 people randomly and mostly they are students and teachers. Since data for this study will be collected by mail or by giving them a questionnaire, the respondents have the convenience of answering the survey in their own home or wherever is comfortable with them. Data Gathering Technique The proponent gathered support documents and point of views of the target users and beneficiaries of the proposed system at the Customs office. The information gathered were compiled and processed for use in the development of the proposed system. The different ways of gathering information and ideas used in this study were: Interview ââ¬â This technique, wherein the proponent discusses and poses question to the respondent, was used to gather data and information for the study. Refer to Appendix ââ¬â B for the contents of the interviews conducted. Questionnaire ââ¬â This data gathering instrument contains a series of formulated questions submitted to a number of people in order to obtain information on a particular subject matter. The proponent prepared printed paper questionnaires and distributed them to the respondents. Refer to Appendix ââ¬â C for a copy of this Questionnaire. Observation ââ¬â This instrument was used in analyzing the existing system. The proponent observed and noted the flow of work in the existing system. The researcher then used it to identify where problems are commonly encountered. The proponent would use the observations to suggest a better and effective system. Refer to Appendix ââ¬â D for notes made during observation tours and meetings. Evaluation ââ¬â This method was used to assess the capability level of the existing and the proposed system software using a set of criteria, namely: accessibility, accuracy, efficiency, and speed and user friendliness. Refer to Appendix ââ¬â E for a copy of the Evaluation Form. Statistical Treatment of Data Information and data gathered in the course of the study were both qualitative and quantitative in form. For the quantitative data, the researcher applied statistical methods of analysis in order to the properly interpret and present data in a more understandable form. The following statistical methods were used to interpret the results: Percentage ââ¬â This statistic refers to the relation between the part under consideration to the whole, expressed in hundredths. Ranking ââ¬â This refers to arranging of scores of the data in numerical order. Frequency ââ¬â This represents the number of respondents that obtained a particular score. Weighted mean Wm = f (x1 + x2 + â⬠¦. xn) N Method Used in Developing the System This part shows the various phases of the software development which are presented as a step-by-step process for the proponent to understand better the development of the proposed system. It is in this stage where the important parts of the proposed system were put together. The proponent used the classical life cycle model which is also known as the waterfall model in developing the system. It views the software process as being made up of number of stages namely: the Planning phase, the Analysis phase, the Design phase, the Development phase and the Implementation phase. Refer to Figure 3. 0. Figure 2. 0 The Waterfall Model By: Ian Somerville Planning Phase ââ¬â In this phase, a study is conducted with the aim of identifying problems in the existing system. It also determines the conditions for solving the problems, whether the proponent should spend more time and work, or gather additional information. The proponent needs an overview of the projected work to determine the, resources needed, the requirements of the system, a graphical outline of the project, and the timetable to adhere with and the projections to make. Analysis Phase ââ¬â This phase is used to have a clear understanding of the existing system in order to identify problems encountered so that it may be corrected or modified. It also identifies the data and processes used in the existing system that would also be used in the proposed system but applied in an automated and organized manner. Design Phase ââ¬â The proponent should design a program with a logical process flow that the target users could easily and clearly understand. Every object in the commands should be in the correct hierarchical position from main to specific functions and processes. The proponent should make a program that is designed to attract the users. Development Phase ââ¬â In this phase, the proponent starts to develop the system using information from the previous phases. With the shortcomings of the existing system identified, the proponent incorporates the solutions that would make the proposed system better. The problems encountered in the existing system are now considered solved with the proposed system an enhanced version of the former. Implementation Phase ââ¬â This is final phase wherein the proposed system is now installed, brought to operation and used. Prior to actual operation, the system is tested for bugs and a simulated run is conducted to verify if the proposed system indeed improves the operations of the existing system. Analytical Tools Analytical tools were used to highlight the various parts the proposed system. They served to give a graphical representation of the system to the system developer. The tools used in developing the software were: Data Flow Diagram (DFD), Visual table of contents (VTOC), Input process and Output (IPO) diagram, Program Flowchart. These were considered very important in developing the system. Program Flowchart ââ¬â This is a logical chart containing symbols referring to computer operations that describe how the program works or performs. This tool was used to design and develop overall software architecture. See Appendix ââ¬â (A) Context Diagram ââ¬â The ââ¬Ëcontextââ¬â¢ of any situation is the external environment in which it exists. In process terms, the context contains other processes that provide inputs and outputs to and from the process in question. See Appendix ââ¬â (B) Visual Table of Contents (VTOC) ââ¬â This shows the hierarchical structure of the system moving from general to specific. It is also the chart that allocates different entities within the main program. See Appendix ââ¬â (C) HIPO (Hierarchy plus Input-Process-Output) ââ¬â technique is a tool for planning and/or documenting a computer program. A HIPO model consists of a hierarchy chart that graphically represents the programââ¬â¢s control structure and a set of IPO (Input-Process-Output) charts that describe the inputs to, the outputs from, and the functions (or processes) performed by each module on the hierarchy chart. See Appendix ââ¬â (E) Proposed System (Screen Layouts) ââ¬â You can see the appearance of the entire skin layout of the system. See Appendix (F) Exploded Diagram ââ¬â A more detailed than the context diagram. See Appendix ââ¬â (G) Data Flow Diagram (DFD) ââ¬â It represents all the entities to the system, the flow of the data from the beginning to the end, together with the processes undertaken. Refer to Appendix G for the Data Flow Diagram used in developing the system. See Appendix ââ¬â (H) Gantt chart ââ¬â is a type of bar chart that illustrates a project schedule. Gantt charts illustrate the start and finish dates of the terminal elements and summary elements of a project. See Appendix ââ¬â (I) Chapter IV.

African American Music essays
African American Music essays By 1945, nearly everyone in the African American community had heard gospel music (2). At this time, gospel music was a sacred folk music with origins in field hollers, work songs, slave songs, Baptist lining hymns, and Negro spirituals. These songs that influenced gospel music were adapted and reworked into expressions of praise and thanks of the community. Although the harmonies were similar to those of the blues or hymns in that they shared the same simplicity, the rhythm was much different. The rhythms often times had the music with its unique accents, the speech, walk, and laughter which brought along with it synchronized movements. (2) The gospel piano style was based on the rhythm section concept, where the middle of the piano was used to support the singers. This area supported the singers by doubling the vocal line in harmony. The bottom, left corner of the piano was used as a bass fiddle while the upper right hand portion played the counter melodies, taking the place of a trumpet or flute. It was the right hand corner that filled in the material during the rhythmic breaks. Often times the text of the gospel songs portrayed meanings of the Trinity, blessings, thanks and lamentations. The singers used the voices to communicate their feelings about Christianity. Many singers sang through the problems and moved their audiences, often congregations, so much so that the audience forgot their own problems temporarily and the weights of the world were taken away through the music. (2) During the beginning of the Golden Age of Gospel (1945-1955), gospel music reached a near perfection and had a huge, devote audience. T he call and response form in particular flourished in the new type of music. The African American gospel song had a unique power and ability to overcome. It was a means of transcending the listeners, singers and entire congregation to a higher spiritual and emotional level. During the post-Civil War years, the congreg...

Cobalt Facts and Physical Properties
Cobalt Facts and Physical Properties Atomic Number: 27 Symbol: Co Atomic Weight: 58.9332 Discovery: George Brandt, circa 1735, maybe 1739 (Sweden) Electron Configuration: [Ar] 4s2 3d7 Word Origin: German Kobald: evil spirit or goblin; Greek cobalos: mine Isotopes: Twenty-six isotopes of cobalt ranging from Co-50 to Co-75. Co-59 is the only stable isotope. Properties Cobalt has a melting point of 1495à °C, boiling point of 2870à °C, specific gravity of 8.9 (20à °C), with a valence of 2 or 3. Cobalt is a hard, brittle metal. It is similar in appearance to iron and nickel. Cobalt has a magnetic permeability around 2/3 that of iron. Cobalt is found as a mixture of two allotropes over a wide temperature range. The b-form is dominant at temperatures under 400à °C, while the a-form predominates at higher temperatures. Uses Cobalt forms many useful alloys. It is alloyed with iron, nickel, and other metals to form Alnico, an alloy with exceptional magnetic strength. Cobalt, chromium, and tungsten may be alloyed to form Stellite, which is used for high-temperature, high-speed cutting tools and dies. Cobalt is used in magnet steels and stainless steels. It is used in electroplating because of its hardness and resistance to oxidation. Cobalt salts are used to impart permanent brilliant blue colors to glass, pottery, enamels, tiles, and porcelain. Cobalt is used to make Sevres and Thenards blue. A cobalt chloride solution is used to make a sympathetic ink. Cobalt is essential for nutrition in many animals. Cobalt-60 is an important gamma source, tracer, and radiotherapeutic agent. Sources: Cobalt is found in the minerals cobaltite, erythrite, and smaltite. It is commonly associated with ores of iron, nickel, silver, lead, and copper. Cobalt is also found in meteorites. Element Classification: Transition Metal Cobalt Physical Data Density (g/cc): 8.9 Melting Point (K): 1768 Boiling Point (K): 3143 Appearance: Hard, ductile, lustrous bluish-gray metal Atomic Radius (pm): 125 Atomic Volume (cc/mol): 6.7 Covalent Radius (pm): 116 Ionic Radius: 63 (3e) 72 (2e) Specific Heat (20à °C J/g mol): 0.456 Fusion Heat (kJ/mol): 15.48 Evaporation Heat (kJ/mol): 389.1 Debye Temperature (K): 385.00 Pauling Negativity Number: 1.88 First Ionizing Energy (kJ/mol): 758.1 Oxidation States: 3, 2, 0, -1 Lattice Structure: Hexagonal Lattice Constant (Ãâ¦): 2.510 CAS Registry Number: 7440-48-4 Cobalt Trivia Cobalt derived its name from German miners. They named cobalt ore after mischievous spirits called kobalds. Cobalt ores commonly contain the useful metals copper and nickel. The problem with cobalt ore is it usually contains arsenic as well. Attempts to smelt the copper and nickel typically failed and would often produce toxic arsenic oxide gases.The brilliant blue color cobalt gives to glass was originally attributed to bismuth. Bismuth is often found with cobalt. Cobalt was isolated by Swedish chemist, Georg Brandt who proved the coloring was due to cobalt.The isotope Co-60 is a strong gamma radiation source. It is used to sterilize food and medical supplies as well as radiation therapy in the treatment of cancer.Cobalt is a central atom in vitamin B-12.Cobalt is ferromagnetic. Cobalt magnets stay magnetic to the highest temperature of any other magnetic element.Cobalt has six oxidation states: 0, 1, 2, 3, 4, and 5. The most common oxidation states are 2 and 3.The oldest cobalt col ored glass was found in Egypt dated between 1550-1292 B.C. Cobalt has an abundance of 25 mg/kg (or parts per million) in the Earths crust.Cobalt has an abundance of 2 x 10-5 mg/L in sea water.Cobalt is used in alloys to increase temperature stability and decrease corrosion.
