Selenium Facts - Periodic Table of the Elements

Selenium Facts - Periodic Table of the Elements Selenium  Basic Facts Atomic Number: 34 Symbol: Se Atomic Weight: 78.96 Discovery: Jà ¶ns Jakob Berzelius and Johan Gottlieb Gahn(Sweden) Electron Configuration: [Ar] 4s2 3d10 4p4 Word Origin: Greek Selene: moon Properties: Selenium has an atomic radius of 117 pm, a melting point of 220.5 °C, boiling point of 685 °C, with oxidation states of 6, 4, and -2. Selenium is a member of the sulfur group of nonmetallic elements and is similar to this element in terms of its forms and compounds. Selenium exhibits photovoltaic action, where light is converted directly into electricity, and photoconductive action, where electrical resistance decreases with increased illumination. Selenium exists in several forms, but is usually prepared with an amorphous or crystalline structure. Amorphous selenium is either red (powder form) or black (vitreous form). Crystalline monoclinic selenium is deep red; crystalline hexagonal selenium, the most stable variety, is gray with a metallic luster. Elemental selenium is fairly nontoxic and is considered an essential trace element for proper nutrition. However, hydrogen selenide (H2Se) and other selenium compounds are extremely toxic, resembling arsenic in their phy siological reactions. Selenium occurs in some soils in amounts sufficient to produce serious effects on animals feeding on plants grown from those soils (e.g., locoweed). Uses: Selenium is used in xerography to copy documents and in photographic toner. It is used in the glass industry to make ruby-red colored glasses and enamels and to decolorize glass. It is used in photocells and light meters. Because it can convert AC electricity to DC, it is widely used in rectifiers. Selenium is a p-type semiconductor below its melting point, which leads to many solid-state and electronics applications. Selenium is also used as an additive to stainless steel. Sources: Selenium occurs in the minerals crooksite and clausthalite. It has been prepared from flue dusts from processing copper sulfide ores, but the anode metal from electrolytic copper refineries is a more common source of selenium. Selenium may be recovered by roasting the mud with soda or sulfuric acid, or by smelting with soda and niter: Cu2Se Na2CO3 2O2 → 2CuO Na2SeO3 CO2 The selenite Na2SeO3 is acidified with sulphuric acid. Tellurites precipitate out of solution, leaving selenous acid, H2SeO3n. Selenium is liberated from selenous acid by SO2 H2SeO3 2SO2 H2O → Se 2H2SO4 Element Classification: Non-Metal Selenium Physical Data Density (g/cc): 4.79 Melting Point (K): 490 Boiling Point (K): 958.1 Critical Temperature (K): 1766 K Appearance: soft, similar to sulfur Isotopes: Selenium has 29 known isotopes including Se-65, Se-67 to Se-94. There are six stable isotopes: Se-74 (0.89% abundance), Se-76 (9.37% abundance), Se-77 (7.63% abundance), Se-78 (23.77% abundance), Se-80 (49.61% abundance) and Se-82 (8.73% abundance). Atomic Radius (pm): 140 Atomic Volume (cc/mol): 16.5 Covalent Radius (pm): 116 Ionic Radius: 42 (6e) 191 (-2e) Specific Heat (20 °C J/g mol): 0.321 (Se-Se) Fusion Heat (kJ/mol): 5.23 Evaporation Heat (kJ/mol): 59.7 Pauling Negativity Number: 2.55 First Ionizing Energy (kJ/mol): 940.4 Oxidation States: 6, 4, -2 Lattice Structure: Hexagonal Lattice Constant (Ã…): 4.360 CAS Registry Number: 7782-49-2 Selenium Trivia: Jà ¶ns Jakob Berzelius found a red sulfur-like deposit at a sulfuric acid manufacturing facility. He originally thought the deposit was the element tellurium. After further examination, he decided he had found a new element. Since tellurium was named after Tellus, or Earth goddess in Latin, he named his new element after the Greek Moon goddess Selene.Selenium is used in anti-dandruff shampoos.Gray selenium conducts electricity better when light is shined on it. Early photoelectric circuits and solar cells used selenium metal.Compounds containing selenium in the -2 oxidation state are called selenides.A combination of bismuth and selenium can be used to replace the more toxic lead in many brass alloys. (Lead is added to brass to increase its ability to be machined)Brazil nuts have the highest levels of nutritional selenium. One ounce of brazil nuts contain 544 micrograms of selenium or 777% the Recommended Daily Allowance. Quiz: Test your new selenium knowledge with the Selenium Facts Quiz.

To Niche or Not to Niche

To Niche or Not to Niche One of the comments I hear most often when I tell friends about my books is, Your writing is too narrow. You need to broaden your appeal. And in a sense, theyre right. There cant be that many people reading about disaffected Mormons. And its not every Mormon who will pick up a book entitled Zombies for Jesus or Sex among the Saints. I started my writing career with an MFA thesis, a collection of short stories about my two years as a gay Mormon missionary in Italy. Now thats specific. I was told at the time, You need to appeal to a larger audience. But my professors werent criticizing me for writing about Mormons. This was the 1980s. They were criticizing me for writing about gays. Today there are so many gay novels being written that a writer would be easily lost amidst the crush of publications. And this is my beef with the criticism in general. My friends tell me to stop writing about Mormons and ex-Mormons and instead just write about people. I assure them that it is hard enough rising to the top among a pool of fifty writers. It would be next to impossible even to be noticed among a pool of tens of thousands. I have another beef with the criticism, too. No good author writes the sentence, The woman put on her best dress, looked in the mirror, and knew she was ready for a fun evening. What in the world does the reader know about how that character looks? We need specifics. Details are what make a story interesting. William Faulkner created an entire career writing about the folks in small-town Mississippi. Those werent just people. They were from a very specific culture and environment. Ill go one further. Isaac Bashevis Singer wrote about ultra-Orthodox Jews in the shtetls of Eastern Europe. Hows that for a niche audience? Especially since Need I remind anyone that both Faulkner and Singer won the Nobel Prize for Literature? Theres no guarantee that Ill ever sell more than four hundred copies of Mormon Underwear or Marginal Mormons, much less win any recognizable awards. But if I just write about generic people, Im even less likely to be noticed. There is simply too much competition out there. Its not a matter of being a big fish in a small pond. Its a matter of finding any water to thrive in at all. Im involved in the Mormon literary community, such as it is. I proofread for a progressive Mormon magazine (yes, there are a good three or four hundred progressive Mormons out there!). I proofread for a small Mormon publisher. I post on the Mormon blogs I follow and my own Mormon-themed blog. I help critique the work of other Mormon and ex-Mormon writers, and I financially support their work as well. And I follow that age-old maxim: write what you know. Yes, I have a niche audience, but the fact is, at least I have an audience.

Personally Identifiable Information (PII) Research Paper - 1

Personally Identifiable Information (PII) - Research Paper Example Information in the modern society is becoming easily available to many people. The internet in specific is one of the main sources through, which many people are obtaining information concerning other persons. Some of the search engines of the internet such as Google can provide important details of a person if well used. Therefore, the private sector as well as public sector should ensure that vital information of people is protected from being accessed by an unauthorized persons. In addition to search engines, social networks are playing a critical role in disclosing personal information, which can be used to for illegal acts. Thus, because of this, various governments and law making agencies have imposed various Acts and Laws in order to enhance Protecting Personal Information (PPI). The legal and federal agencies have a mandate to protect sensitive information of people from unauthorized access. The Privacy Act (1974) was the first legislation created to oversee that personal information is safeguarded. The Act was established amidst rising concerns on the impact of computer databases on the private rights of individuals. The Act details how, what, or when the information is to be disclosed. The State, Federal and Local agencies shall collect information to help them conducting their businesses but should properly protect the data from the unauthorized intrusion. The U.S. Department of Commerce (DOC) in partnership with ‘National Institute of Standards and Technology (NIST)’ established Special Publication (SP) 800-122, which protects the PII existing in databases. ‘The National Institute of Standards and Technology’ proposes that agencies should establish safeguards to ensure proper handling of the information. In this regard therefore, organizations should enforce the following; creation of policies and procedures for PPI, conducting appropriate training of employees to reduce the

Greek Microsoft - Case Study Example He/she will be responsible for the AntiPiracy organization to maximize efficiency of AntiPiracy programs externally throughout customer segments and Reseller's channel & internally for all employees driving AntiPiracy education and readiness campaigns (eg. what is Intellectual Property (IP), SW Asset management (SAM) etc). In addition, for building an external, cross-industry coalition and managing relationships with third party influential's to maximize the impact that we have on government engagement efforts targeting local and foreign influencers to combat piracy." Ten years ago the specific sub was rather small (30 employees). The General Manager was the leader and followed all Microsoft guidelines for personnel and management. This sub was particularly important for the Middle East Africa region therefore there was an interest from the headquarters for the sub's profits and sales turnover. After a major reengineering the sub moved to the EMEA (Europe Middle East Africa) region and its importance was significantly reduced. The Antipiracy Manager's position lost its importance since it became a subordinate of Small and Medium Enterprises Manager (SME) instead of the General Manager as it was before. The work environment, prior to the move to EMEA, was comfortable and employees felt they had initiative and their efforts were rewarded accordingly. When the sub moved to EMEA, a new General Manager took over the position as the old one resigned. The new GM did not have any experience of the software industry (his experience was in Digital, PC hardware) and his leadership style was different. He made his decisions based solely on his Direct Reports feedback without cross checking the info he had and without having first hand experience. This fact plus his non software experience created a very negative work environment. Employees' performance appraisal was based on their good or bad working relationships with the managers and not on objective and measurable criteria. People started playing "politics" instead of being productive. As a result, the sales turnover of the sub, after having seven consecutive years increase, was reduced significantly. The new GM was fired after having only two years work experience at the sub. Brief analysis of the theory of Emotional intelligence and the role of a positive environment. D. Goleman (2000) defines Emotional Intelligence as the ability to recognize our own feelings as well as the feelings of others, to create motives for ourselves and to handle correctly our feelings and our

Evolution of Theoretical Knowledge of nursing Essay Example for Free

Evolution of Theoretical Knowledge of nursing Essay The ultimate goal of the nurse is to maintain, and restore the health of the patient. Nursing is considered both a science and an art. The application of nursing knowledge and the technical aspects of the practice is considered the science. The establishment of a caring relationship through the application of nursing knowledge and judgment is used in a compassionate manner and is seen as an art. (College of Nurses 1999 June Nursing and You Volume1, number 3 p3) This paper will attempt to explain the four concepts of the nursing metapardigm as it relates to the person environment, health and nursing. A person is seen as an individual possessing their own uniqueness, personalities and having their individual needs. A person should be treated with respect and dignity regardless of their cultural, religious, socio-economic class, marital status or sexual preferences. The individual should not encounter any bias or discrimination in school, employment or when the need arises for medical care. Each person has their basic needs that must be met while progressing through the different stages of development. One should be given choices, and be allowed to have an input in their care or treatment plan. They should be allowed to excel and strive to achieve their goals. Be able to reside and work in their chosen location and field as long as they are qualified for the job. They are usually part of a family belonging to a cultural group, living within a community or region of their choice. The environment can be open or closed. It can contribute to the building or endangering of the persons self esteem. One might adapt to the environment depending on ones personal preference. A person might be seen in the eyes of others as the product of their environment that might be interpreted as a negative or a positive statement. Depending on ones interpretation of the statement. Some environments have sub-cultures within the environment. Each group has different beliefs, such as religion, diet, attire, and dialects. The environment sometimes contributes to some medical problems, for example respiratory problems. Nurses unfamiliar with the laws and customs of the environment might need to familiarize themselves with cultural practices. What is appropriate and inappropriate for that culture for example male  nurses not allowed to give care to female patients in t hat environment and vice versa. Nurses might need to observe the environment for safety precautions and life threatening situations. Which will contribute or cause an illness, or preventing recovery. The environment is considered home and that is were the person resides. It is a familiar surrounding for the individual. Health can be defined as freedom from either a mental or physical condition, which impedes one from performing activities of daily living or preventing the person from functioning at their optimum level, for that individual. The person is considered mentally or physically stable or unstable depending on the diagnosis he/she is assigned. Health is when a person is in a state of well-being. The individual has been free of pain and disease. The patient is always the focus; therefore it is called patient focused care. Health is considered the quality of life, when an individual is independent and able to function without any obstacles of impedement. Nursing can be defined as one being trained in both theory and practice. Virgina Henderson also stated that nursing is an independent unique health profession carrying out activities with or on behalf of the patient that contributes to health or recovery (or to a peaceful death) that the patient would perform unaided given the necessary strength, will or knowledge. (Nursing Foundation (1999) Basic Elements of Selected Conceptual Models p 314). In nursing the nurse should be able to critical think, be caring, competent, compassionate and have a conscience according to Roach. (Roach 1992). Nursing would include, doing a nursing assessment, nursing diagnosis, nursing care plan, and a nursing interventions. Starting with short-term goals, and upon achieving short-term goals for the patient, then proceed to long-term goals. Goals should be realistic. Then evaluate and reassess if the needs arises. Problem solving and treating the patients as human, the same way you would like to be treated. Working in a mental Health hospital, the client is seen as a whole person, a human being. A person who is unable to cope, survive or function at their optimum level in the community, due to mental illness. Patients diagnosed with a mental illness, and are being cared for in the hospital. Their mental  status is monitored, and they are assessed on an ongoing basis. Patients are encouraged by nursing staff to verbalize their concerns, so staff can be aware of their needs, which will promote stabilization of the patient, diagnosed with a mental disorder. The environment in which the patient resides should be non-threatening therapeutic and be conducive to healing. The environment might be seen as open or closed depending on ones perception. Health is interpreted differently, depending on the cultural, religious background of the person and their knowledge base, regarding health. With mental illness, the patients medication might need to be adjusted. Which will modify the behaviour and stabilized the patient at the same time. Assisting the patient to function at their optimum level, giving choices and promoting independence. My thinking represents a combination of worldviews. I looked at the whole person; reflect on the things that I could have done better. I attempt to understand the behaviors and practices of certain cultures. Gaining an understanding of the culture by using the deductionist path of science along with historical views of the person within the environment. As environment shape behaviors at times, I look at a combination of worldviews to determine each metapardigm.

The First Female Prime Minister of Canada :: essays research papers

Kim Campbell, Canada's first female Prime Minister, rose quickly in her political standings reaching, what she would find to be the height of her career only seven years after entering politics. It appeared like the loss of the 1993 election and the all around destruction of the Progressive Conservative party was completely Kim Campbell’s fault however actually was a joint effort by Brian Mulroney and Kim Campbell. Kim Campbell rose so quickly in her political status that she did not have the experience that most of the others MPs had at her level. The Tories were finishing their second term in power and the people of Canada were displeased with Brain Mulroney by the time of his resignation. Kim Campbell was voted in as Prime Minister by her party and was not elected by the people of Canada. During the 1993 election Kim Campbell had an American company make a commercial that mocked Liberal party leader Jean Chrà ©tien’s physical disability. Kim Campbell’s first entered politics in 1986. She first won a provincial seat in Vancouver and in 1988 she won her bid for the House of Commons. She had many good ideas, one of them being the USA-Canada Free Trade Agreement. This part of her campaign was recognized by Brian Mulroney who was the current Prime Minister. In 1989 Mulroney appointed Kim Campbell to the position of Minister of State for Indian and Northern Affairs. Later, in 1990 she was appointed Minister of Justice and a year later became the Minister of Defence. Just two years after becoming Minister of Defence and 7 years after entering politics, she ran for leader of the Progressive Conservative party and became Brian Mulroney's successor. Kim Campbell inexperience in the world of politics gave her a huge disadvantage when things started to go wrong. Brain Mulroney and the Tories had been in power for two terms, a total of 9 years. The Canadians had become tired of Brian Mulroney and his Progressive Conservative government, so when it w as announced that he would resign most Canadians were happy to see him go. However his resignation did mean the end of the Progressive Conservatives power in Canada. Canadians unhappy with what the Progressive Conservatives had done chose to elect an other party. When Brain Mulroney resigned there was, in place of a federal election, a leadership convention. The Tories just had to elect a new leader who would then become the Prime Minister.

The controversy and the future of Common Agricultural Policy of European Union

Agriculture is a problematic area in every developed country. Free market economy that allows direct competition of agricultural products can often cause a surplus or shortage of certain products, and quality changes. In order to ensure reliable supply of food member states of the European Union decided to cooperate and transferred the authority over agriculture policy to European level. Common Agricultural Policy was set in 1961 and its aims were to improve production and solve existing problems in agriculture all over EU member states. The previous successes of cooperation with coal and steel, and the fact that most states had difficulties to produce certain goods logically led to deeper cooperation in agriculture, and to CAP. Today, â€Å"CAP is regarded as the most developed of the European Union's policies and covers almost 90% of all agricultural products† (reader). But, also it is regarded as the most controversial and has been responsible for some negative consequences on the industry, and it had to go under many reforms. This essay will explain why CAP has been both celebrated and criticized. Also, it will include the challenges that will be put in front of it by the future enlargement of European Union. At the time CAP was made, national agricultures had all common problems. Although the different level of development, and different level on dependence on this industry between member states of EC, there were some immense troubles to be solved by Cap: deficits of certain goods, inefficient production practices, poorness of people employed in agriculture, rapidly dynamic prices, substantial variations in quality of products etc. The goals of policy defined in Maastricht Treaty, article 39: â€Å"(a) to increase agricultural productivity by promoting technical progress and by ensuring the rational development of agricultural production and the optimum utilization of the factors of production, in particular labor; (b) thus to ensure a fair standard of living for the agricultural community, in particular by increasing the individual earnings of persons engaged in agriculture; (c) to stabilize markets; (d) to assure the availability of supplies; (e) to ensure that supplies reach the consumers at reasonable prices.† (TEU) Since its foundation CAP has improved the agriculture of Europe in a great sense, but critics would say that costs of the successes are considerably high for all. Some of the goals were fulfilled with little negative consequences, while others were solved with controversial methods that became a huge burden for the budget and had many counter-effects. The changes in Europe's agricultural structure and productivity since 1961 caused by CAP were enormous. Thanks to the investment in technology, there was a growth in productivity of farms, decrease in people employed in agriculture, rapid urbanization and therefore prosperity in other sectors of economy. Statistics show that â€Å"the workforce employed in agriculture declined from 11.3% in 1973 to 9.4% in 1980 and only 5.7% in the whole of the EU in 1992.† (Hitiris, 190) Productivity growth was rapid, and we can say that the aim of CAP to restructure the farming to make it more efficient is being fulfilled. The growth of the efficiency of the labor can be noticed on the fact that: † In 1960 over 15 million people in the original six had worked on the land. In the mid-1970s the agricultural population of the enlarged EC was only 14 million, falling to 10 million by the mid-1980s† (Urwin, 187) Second goal of CAP is a social mission: to help the quality of life of the people in agriculture. This went little against the economic productivity and caused many negative consequences on it, especially by huge costs. The interventions that were made were not only subsidizing the farmers, that is a huge burden for EU budget but artificial manipulations with prices and setting of standards. These two were criticized by many liberal economists as standardization brought prices up, and artificial price setting caused surpluses and deficits.

Copyright  © 2008, Ivey Management Services Version: (A) 2008-08-22 â€Å"Don’t forget, your business idea pitch is due in two weeks, † said Professor Sharen at the end of class. Jessica Pierce turned to look at her project team mate, Ashley Mound.Jessica and Ashley were fourth-year management and organizational studies students at Brescia University College, taking an introduction to entrepreneurship course. Ashley and Jessica had developed an idea for the assignment: a personal safety alarm that both shrieked and flashed lights when the person carrying it set off the alarm function. Given the concern that many people had over personal safety, it seemed like a great business idea. In order to present their idea, they needed to show that there was a market for this product and that they had a way to sell it to consumers.The problem was that they did not really know how or where to start to get the information that they needed. They had a lot of work to do to be ready to present their project in the next two weeks. THE ASSIGNMENT The business pitch assignment was challenging. Sharen had asked students to deve lop an interesting business idea and present it to a panel of potential investors. These investors included a successful serial entrepreneur, a business consultant who practised in the area of small- and medium-size enterprises, an owner of a marketing and advertising services business and a business professor.The students were asked to present an innovative idea, show why it would be successful in the market place, demonstrate potential markets, show the business model and sell themselves to the investors as entrepreneurs. The investors were instructed to view their investments as seed money to enable the students to further develop business plans and prototypes of their ideas. The students weren’t required to complete a financial analysis for this assignment. Purchased by Gaia Cuccarini (gaia. [email  protected] it) on March 21, 2013 Page 2 9B08M057The investors were asked to assess project ideas on the basis of the feasibility of the idea and whether they believed that t he entrepreneurs would be able to deliver. They could consider the appeal of the idea itself, the logistics and operations required to run the business, the effectiveness of the business plan, the longterm viability of the business or the size of the market. The assignment would be graded 50 per cent based on how much money the teams received from the investors and 50 per cent on the quality of their presentation by the professor. THE IDEA The Piercer was a small device that hung on a chain worn around the neck.When activated, The Piercer emitted a piercing sound that traveled for approximately 500 meters, as well as a bright flashing light. To deactivate The Piercer, the wearer had to push two buttons simultaneously. This was to prevent an attacker from being able to deactivate the device. The piercing noise and the bright flashing light were designed to scare away attackers and attract those who might assist the person being attacked. In the situation of imminent attack, a person would not have to rely on their voice or bring a whistle to their mouth to signal for help.Ashley and Jessica had researched costs and thought that by manufacturing in China, they could make The Piercer for $2 and sell it for $7. 50 wholesale, with a retail price of $14. 95. The idea made sense to Ashley and Jessica. It fit with recent social and demographic trends as aging baby boomers began to need assistance with injuries and falls, and with increased general concerns about health, safety and violence. WHAT NEXT? Jessica and Ashley thought that they had a good idea. Now they had to prove it. What were the target markets for this product? How big were they?Which ones should they choose? How should they sell to them? What proportion of the target market should they expect to capture? Where should they look for information to help them make these decisions? A SIMPLE GUIDE TO INFORMATION RESOURCES AND EVALUATION Ashley and Jessica must do secondary research to be able to evaluate and implement their idea. They will need to consider 1) how to evaluate resources, 2) how to develop effective search strategies and 3) how to identify proprietary resources that support the case for this business. 1. How to Evaluate ResourcesInformation is available everywhere, and for this reason, Jessica and Ashley need to be able to discriminate between good and poor quality information. Appropriate information usage for an academic project includes evaluating and assessing resources for reliability and credibility. Purchased by Gaia Cuccarini (gaia. [email  protected] it) on March 21, 2013 Page 3 9B08M057 Goals ? ? ? ? ? Ashley and Jessica should be able to locate and differentiate free versus proprietary web resources. They should be able to identify a quality website. They should be able to evaluate books and other print resources for quality and reliability.They should understand the difference between scholarly and non-scholarly articles and resources. They should be able to cite information properly. Free Versus Proprietary Web Resources Many students think that the World Wide Web has the answers for everything. While the web can have valuable information, students pay (through their tuition) to have access to quality proprietary information resources. Ashley and Jessica could examine some free web sites to help them. For example, associations, company information and government information can be very helpful, as long as the user knows how to determine the quality of a website.Quality Web Sites Anyone anywhere can make a website. Just because it is on the web, does not mean it is good quality or reliable. When Ashley and Jessica are evaluating websites, they need to consider: Who is providing the information? ? Is it a government institution, a university or a company? ? Does the url make sense (e. g. .org, . edu, . on. ca)? ? Does the owner of the website have anything to gain by providing the information? ? Does the owner of the website have good c redentials? ? Has anyone updated the website recently? Note that Wikipedia is not necessarily a reliable resource.Anyone anywhere can modify these pages. While it might be a place to find some resources or links, students should not cite Wikipedia as a reliable resource in an academic paper. The University of Alberta put together a good web evaluation checklist: http://www. library. ualberta. ca/instruction/science/evalweb. pdf For a more comprehensive list on evaluating web resources, see the bibliography on the topic: http://www. lib. vt. edu/help/instruct/evaluate/evalbiblio. html Purchased by Gaia Cuccarini (gaia. [email  protected] it) on March 21, 2013 Page 4 9B08M057Evaluating Other Resources Ashley and Jessica need to be critical of all the resources they use, not just websites. Ideally, they should be able to discriminate between proprietary and non-proprietary websites, scholarly and non-scholarly resources and evaluate the quality of any book used. Things for Ashley and Jessica to consider include: ? Who published the book or made the information available? ? How old is the information? ? Has the information been updated recently? ? Is the information peer reviewed? Does this matter? ? Did the library buy and recommend the resource? Is the author credible? Scholarly Versus Non-Scholarly Resources An academic library will provide access to both scholarly and non-scholarly resources. Scholarly work generally refers to published work that has been through a peer review process. Especially in the field of business, there are many practitioner resources. Therefore, Jessica and Ashley need to be aware of the type of information they are gathering. For example, industry trends, say from Standard and Poors NetAdvantage, is not a scholarly resource, yet the information within them could be valuable.Alternatively, ProQuest ABI Inform Global provides access to scholarly articles. Ashley and Jessica may also consider the relative value of evidence or fact ver sus opinion. Students should not read things and trust that what they are reading is accurate. Students should think about the rigor with which the argument is made and the evidence presented. ? Is there evidence to back up a claim? ? Has the evidence been collected in a reliable way? ? Is the author stating an opinion without backing up his or her ideas? Citing Work It is important that Ashley and Jessica cited their work properly, to avoid accidental plagiarism.Some of the more confusing things to cite include Statistics Canada data or online information. Statistics Canada has a website that describes systematically how to cite its tables, publications or other datasets: http://www. statcan. ca/english/freepub/12-591-XIE/12-591-XIE2006001. htm In addition, most academic libraries will have information about citation procedures, or will have copies of publication manuals available for borrowing. Any librarian can be asked about citation procedures. Purchased by Gaia Cuccarini (gaia . [email  protected] it) on March 21, 2013 Page 5 9B08M057 2. How to Develop Search StrategiesGoals ? ? ? ? Ashley and Jessica should know the difference between searching in different search fields, such as the abstract field and title field They should be able to use this technology to search the unique fields They should be able to use the â€Å"AND,† â€Å"OR,† or â€Å"NOT† features of a search engine to help narrow their search. They should understand what truncation and proximity search strategies are, and how that influences a search. Most search engines that index information have similar features. If Ashley and Jessica understand the concepts in searching, they can apply them to any search engine.Take Advantage of Search Fields For example, records in an index have many different fields such as keywords, title, author, publication title, document title, abstract, full document, date, author, etc. It is often possible to specify what part of the recor d to search in, which helps to be more specific with the search. Searching an entire text document may retrieve less meaningful records than a search of just abstracts. Use Boolean Search Strategies Using â€Å"AND† and â€Å"OR† can be helpful in expanding or narrowing a search. AND narrows a search and OR expands it. Using the term â€Å"NOT† can also be helpful, but should be limited.For example, searching for beer companies will retrieve companies on diamonds (DeBeers). Excluding the term â€Å"diamond† from a search on beer companies could be helpful in narrowing one’s search. Truncation and Proximity Many search engines allow for truncation and proximity searching. In ProQuest, an asterisk symbol will truncate. For example, if one types â€Å"leader*† into a search box, records with leader, leaders and leadership will be retrieved. This helps capture all variations of a word. Proximity searching refers to how close two words are togeth er in a document.Presumably, if two words are close together in a document, they are more likely to have something to do with each other. In ProQuest, a â€Å"w/1† or â€Å"w/2† (â€Å"w/3,† etc. ) facilitates proximity searching. For example, if Ashley or Jessica typed â€Å"organizational w/3 learning† in the search box, they will retrieve documents where the word â€Å"organizational† is within three words of â€Å"learning. † Find Creative Ways In There are many different ways to find information. Knowing a company name or a competitor’s name is convenient. Taking advantage of key words (or subject terms) also is a good way to search.Purchased by Gaia Cuccarini (gaia. [email  protected] it) on March 21, 2013 Page 6 9B08M057 It is also a good idea to brainstorm for synonyms prior to beginning a search. Being d eliberate about a search strategy and deciding on what concepts to combine can really help make the search go easier. Sea rching is iterative as well. One is advised to read some articles to learn the jargon of the topic, then go back and do the search again using the subject jargon. Most librarians will help on developing a search strategy! 3. How to Identify Proprietary Resources GoalsAshley and Jessica should be able to identify library resources and understand what type of information they can find in various types of resources. The following databases are some of the library databases that Ashley and Jessica could consider. They could also go to the library (or call or e-mail) and ask for assistance. Library staff will know what resources the library has, if there are any other resources that may be of use and how to access and use the resources. Finding Background Scholarly Articles ProQuest ABI Inform Global is a database that indexes business and management journal articles.Most of the articles are available in full text, and both scholarly and non-scholarly articles are available. The search b ox in ProQuest has a drop-down menu on the right that allows users to search in specific fields. For example, users can search the title, abstract, author, company or publication fields. Scopus is a database that indexes articles on the social sciences, life sciences, physical sciences and health sciences. For the purposes of a business or entrepreneurship project, searching only the social sciences category would be appropriate. This resource indexed scholarly articles.Google Scholar is a free resource that indexes scholarly information from the World Wide Web. There is an advanced search engine feature to help specify a search. Many academic institutions integrate access to full text articles with Google Scholar. This means that any article the student has access to via the library, is also available to them via Google Scholar. Because Google Scholar is integrated with library resources, the student will likely need to either be on campus, or logged into the off-campus proxy serve r to take advantage of these services.If they are off campus or not logged into the proxy server the student can still search Google Scholar, but access to full text resources may be limited. Finding News and Magazine Articles Factiva is a database that indexes newspapers and magazines. While this resource does not index scholarly articles, it is a broad resource that captures current global news and events. LexisNexis has a comprehensive database that indexes newspapers and magazines. significant Canadian content indexed there. Purchased by Gaia Cuccarini (gaia. [email  protected] it) on March 21, 2013 There is alsoPage 7 9B08M057 Finding Industry Trends Several databases including Standard & Poors NetAdvantage, Mintel and Marketline provide reports on industry trends. These databases provide regularly updated reports on broad industries. Each database tends to report on different industries, so students would have to do some trial and error research to find relevant reports. Stu dents may find their topic is too narrow for these reports. The Financial Post Investor Suite is a database that provides industry information from a Canadian perspective. Finding Company InformationCompany information may be important for a project such as The Piercer, especially for researching competitors. MarketLine provides company information, including financial information, company descriptions and a list of competitors. Similarly, Hoovers provides comprehensive company descriptions. Not all companies are in both resources, therefore checking both resources is recommended for company research. Marketing and Advertising The World Advertising Research Center (WARC) is a resource that provides access to information about marketing and advertising, as well as to case studies of winning ad campaigns.Such a resource could be helpful in this context to see if other, similar products have been marketed, and if so, how they have been marketed. There is scholarly and non-scholarly inf ormation in this resource. Technology Information Both eMarketer and Forrester have information about technology trends. There may be information about the Internet, emerging technologies or electronic marketing. Statistics and Demographics Statistics Canada provides access to demographic data. Many secondary educational institutions participate in the Data Liberation Initiative.This means that information a member of the public would have to pay for, can be retrieved for free by a student. Students, through the academic library website, can use data for research. For more information about accessing statistics, students can talk to their subject librarian. Some resources that Statistics Canada has that might be useful to find demographics include the Market Research Handbook, Canadian Business Patterns, CANSIM data, Census data, and Canadian Social Trends, among others. There are other resources available via www. statcan. ca such as Community Profiles.Data are available down to gr oupings of the population of about 2,000 to 7,000 people, meaning students can find demographic data for each 2,000- to 7,000-person neighbourhood across the country. Purchased by Gaia Cuccarini (gaia. [email  protected] it) on March 21, 2013 Page 8 9B08M057 Global Information Although global research may not be as important for a product such as The Piercer, other entrepreneurial projects may require researching the global market. Economic Intelligence Unit, Global Market Information Database and Business Monitor Online are three resources that provide global market and industry information.Other Helpful Resources Students are encouraged to use the World Wide Web to help them find good information. For example, city homepages often have information about setting up a business. Association websites also can have helpful information. Also, banks have entrepreneurial information on their websites. In addition, many books in the library explain how to develop small business plans or provide information on entrepreneurship. Purchased by Gaia Cuccarini (gaia.

Free Essays on Identity And Social Structure (Reflective Essay)

Reflective Essay: Identity and Social Structure Throughout the semester, we have examined the complex relationship between a person’s identity and his or her social experience. This relationship is not easily defined, and I believe that the extent to which its two components (identity and social structure) are influenced by each other differs from culture to culture, and furthermore, from individual to individual. The questions which we are to address in this essay, therefore, have no clear-cut answers, so the most that this paper can hope to do is to present the insights that I have gleaned from this class, in light of the background information I had prior to the class. Essentially, I believe that society defines the type of experiences a person has, and that those experiences, in turn, play the most important part in shaping identity and/or personality. Every individual lives within a society of some description, and in order to survive, (let alone succeed) in their society, a person must operate within societal parameters. As we have learned, society is the result of economic condition, political situation, and (perhaps most importantly) the discourse generated and propagated by its people. Each human society has all of these components, but the nature of the components varies; as I have said, every society has a unique set of parameters. Goffman has pointed out that humans are highly adaptive to various social situations. In order for an individual to choose how (s)he will function in a given situation (in Goffman’s terminology, the â€Å"mask† (s)he will wear), (s)he must draw on the discourse present in their society. Not only does discourse define the various â€Å"masks† available to a person within their social context, it also allows a person to gauge how best to react to the â€Å"masks† of those with whom (s)he comes into contact. â€Å"Masks,† it would seem,...

Make Potassium Chlorate From Bleach and Salt Substitute

Make Potassium Chlorate From Bleach and Salt Substitute Potassium chlorate is an important potassium compound that can be used as an oxidizer, disinfectant, source of oxygen, and component in pyrotechnics and chemistry demonstrations. You can make potassium chlorate from common household bleach and salt substitute. The reaction is not particularly efficient, but its something to keep in mind if you need potassium chlorate right away or just want to know how to make it. Key Takeaways: Make Potassium Chlorate From Bleach and Salt Substitute Potassium chlorate is used as an oxidizer, disinfectant, and colorant (purple) in chemistry demonstrations and fireworks projects.While its not the most efficient chemical reaction, its simple to make potassium chlorate by boiling bleach, cooling it, and mixing in a saturated solution of salt substitute in water.The synthesis works because potassium from the salt substitute displaces sodium from the sodium chlorate made by boiling the bleach. The product is sodium chloride and potassium chlorate. Since potassium chlorate is not very soluble in water, it precipitates and may be collected by filtration. Materials for Making Potassium Chlorate You only need two ingredients to synthesize potassium chlorate: Chlorine bleachPotassium chloride (sold as a salt substitute)Filter paper or coffee filter Take care to check the label on the salt substitute to make certain the ingredient is just potassium chloride. While salt substitute is potassium chloride, lite salt is a mixture of sodium chloride (table salt) and potassium chloride. The reason this project works is because potassium replaces sodium in sodium chlorate. Basically, you need to make certain you are supplying the potassium. While it shouldnt be significant, keep in mind household bleach has a shelf life. If your bottle of bleach has been opened and stored a long time, its a good idea to get a fresh one for the project. Prepare Potassium Chlorate Boil a large volume (at least a half liter) of chlorine bleach, just until crystals start to form. Do this outdoors or under a fume hood, to avoid inhaling the vapor. Boiling bleach disproportionates sodium hypochlorite into sodium chloride and sodium chlorate.3 NaClO → 2 NaCl NaClO3As soon as crystals start to form, remove the bleach from heat and allow it to cool.In a separate container, prepare a saturated solution of potassium chloride by stirring potassium chloride into the water until no more will dissolve.Mix equal volumes of the boiled bleach solution and potassium chloride solution, taking care to keep solids from either solution out of the mixture. This is a substitution or single replacement reaction. The two products are separated based on solubility. Potassium chlorate will precipitate out, leaving sodium chloride in solution.KCl NaClO3 → NaCl KClO3Cool the solution in the freezer to increase the potassium chlorate yield.Filter the mixture through filter paper or a coffee filter. Keep the solid potassium chlorate; discard the sodium chloride solution. Allow the potassium chlorate to dry before storing or using it. NurdRage has a video of the process if youd prefer to see how its done. Potassium chlorate is used in fireworks as an oxidizer and to produce a purple flame. Teeraphon Phooma / EyeEm / Getty Images You can test the potassium chlorate in a simple chemistry demonstration: Purple Fire (shown) - Mix potassium chlorate and half as much sugar. Ignite the mixture either by applying a flame or adding a few drops of sulfuric acid (instant chemical fire).Dancing Gummi Bear - The candy is the source of the sugar in this demonstration. The vigorous reaction between the candy bear and the potassium chlorate makes the bear appear to dance in purple fire. Other uses of potassium chlorate include safety matches, fireworks, disinfectants, pesticides, firearm primer, and to force plant blooming. It is also a good starting point to prepare oxygen gas or chlorine gas. Safety Tips This is a project that should be performed with responsible adult supervision. Undiluted bleach can cause skin irritation and damage eyes and mucous membranes if splashed. Heating bleach should be done outdoors or under a fume hood, as irritating vapors are released. Finally, keep the potassium chlorate collected in this project away from heat or flame until you are ready to use it. It should be stored away from sulfuric acid and sulfur, as spontaneous ignition may occur.

Grounded theory approach Research Paper Example | Topics and Well Written Essays - 250 words

Grounded theory approach - Research Paper Example Lost potential to manage muscles in the hand is an example and has many effects on the individuals. A person with Fine Motor Skill Disability may for example not be able to hold a pen firmly and write with it or even function effectively in physical activities that engage the affected muscles (Nicholls and Jones, 2012). Emerging trends in technology can however empower this population and this paper explores the population’s experience with technology to develop a theory on empowerment effect of technology on the population’s ability to participate in graphic design. In order to explore the research questions, the study will use a list of students with Fine Motor Skill Disability, from an academic institution, to generate a corresponding list of the students’ parents and teachers. Stratified random sampling will then generate a sample of 25 participants from the three groups with 11 participants being students with the disability. Interviews and observations will be used in data collection. The students will be interviewed on their experiences and opinion over derived benefits of technology in graphic design and their successful implementation of technology in design observed. Interviews will however be used in collecting data from the parents and teachers regarding effects of technology on the disabled students’ attitude and success in graphic design (Johnson and Chrisensen,
