Comparison of Operating System Kernels - Essay Example Different kinds of operating systems are available and in completion amongst one another. These come in form of products from Microsoft, Apple, Linux, FreeBSD and many more. Each of them has a large customer bench and has its own characteristics; it is these characteristics that make them unique and most sought after. At the same time these characteristics are totally unique in their way and facilitate the users in many ways. Computer itself is a large entity, and has many components such as memory unit, processing unit, operating system, cache, and many more parts. It is the operating system that holds the kernel within itself. Kernel is a series of instructions, processes and programs that are joined together, grouped into large entity to perform the tasks. For example a particular process, and a particular program may be designed to execute a certain function, the kernel is a larger entity that is created to enable execution of the entire operating system. While programs are related to the virtual mode, the kernel is also concerned with the physical mode and physical operations as well. Kernel is that part which provides a bridge between the software and hardware; it acts as an intermediate source between the two and facilitates each of them in making up an entire computer system for purpose of all the operations that we perform on the outside face of it(Pfleeger & Pfleeger, 2012,351). Before creating a kernel, a lot of thought is invested in to it, this thought pertains to the kind of customers it would entertain, the kind of functions it would provide, what capacity it would support, and most importantly the kind of work that would be performed by it. Based on these considerations, the kernels are designed to provide maximum benefit to the users and enrich the usage of computers along with aim of providing maximum ease. Other factors which distinguish the kernels support and

Role of Press in Society Essay Example for Free

Role of Press in Society Essay Many kings and emperors ruled Delhi over the years and, therefore, it abounds in monuments. People come from far and wide to see them. They have an educational value. Once when we had our Dussehra holidays, we went to see places of historical importance with our teacher. We hired a bus. First we went to the Qutab. It is now a building of five storeys. Two of its upper storeys had been brought down. It was built by Qutab-ud-Din, the first slave king of India. We admired the architectural beauty of the building. We went up to the highest storey and watched the people below. They looked like dwarfs. We also saw the iron pillar standing nearby. It is known as King Chandras pillar. It is more than two-thousand-year-old. Next we went to see the carvings of Hindu gods and goddesses on stone slabs. We were really surprised to see the wooden slabs changing into tone. From the Qutab we went to Tughlaqabad. Here an old city of Delhi, founded by Tughlaq Kings, was once situated. Now it lies in ruins. Then we proceeded to Hauz Khas which was the residence of kings. We relaxed for sometime on the green lawns. We had our lunch here and refreshed ourselves with tea. Next we went to Humayuns Tomb where Emperor Humayun lies buried. We appreciated the Mughal art and architecture. There are graves of the Mughals nearby. Our next place of visit was Kotla Feroze Shah. Feroze Shah Bahadurs tomb and a mosque are built in it. This place is known for the Ashoka pillar, which was brought from Meerut. Next we saw the ruins of Old Fort. It was started by Humayun but was completed by Sher Shah Suri. In the end we went to the Red Fort. It is a fine building of majestic grandeur. There we saw Diwan-i-Khas. It shows the architectural taste of the great Mughal Emperor, Shah Jahan. The glory of the ancient ages is writ large on its face. We visited the museum inside the fort. Many things of historical value are displayed here. We learnt a lot from the visit and eagerly desired to have another educational tour of Delhi.

The Crucible: A Masterpiece of Dramatic Writing Essay -- Essay on The

  Ã‚  Ã‚  Ã‚  Ã‚   The Crucible provides us with an example of a masterpiece of dramatic writing. In this play Arthur Miller gives us a stimulating example of the use of a variety of theatrical techniques. His most powerful scenes in "The Crucible" have common characteristics: very effective use of stage actions, long build-ups of suspense that come crashing down in thundering climaxes, intense displays of emotion and an abundance of dramatic irony. These are my three chosen scenes: p46-50: "Tituba........Devil!", p98-100: "She thinks.......Oh God" and p101-105: "You will.....Mr Hale!". Because of the importance of these scenes as key moments in the play Miller makes them dramatically superb so that the "No,sir" by Elizabeth that decides the outcome of dozens of lives and of her own and her husband’s, John Proctor is also the climax of the most effective build-up of suspense in the play. The effectivness of these scenes is also enhanced by powerful characters such as John Pr octor and Danforth who display such intensity in their emotions and actions that the audience can not help but be moved. But most of all, these scenes show Miller’s theatrical qualities so that by the end of each of these scenes we not only understand his message but also find ourself convinced by his arguments . The dramatic impact of a play is enhanced when the audience understands all the different aspects of the main characters. It helps them become more involved and at the same time gives the author the chance to display some dramatic irony. Miller uses stage actions to that end in the first chosen scene of "The Crucible". In this scene Tituba’s inner conflict and Hale’s resolution is clearly expressed through the stage actions. Tituba first denies having seen ... ... power. "The Crucible" is considered by many Miller’s masterpiece, it both displays his dramatic and theatrical qualities in such a way as to make it disturbing and socially relevant. In it one can find his views on society as a whole and on current events such as Mccarthyism which similarily to the medieval Church and justice system searched for individuals who by their ideals and ideas they felt threatened the supremacy of their system. Miller made "The Crucible" the starting point for the audience to reflect on their own society and culture. But at the same time Miller polished his deep philosophical work with superb stage directions, likeable characters and nerve-racking suspense.

Priceline Business Model

Priceline Business Model The core components of Priceline’s business model are based around their pioneered and patented reverse auction pricing model which is a unique offering within the travel market place. This innovative model allows consumers to purchase travel services at a discounted prices by trading off brand and features. Priceline uses a business model known as brokerage model where a business creates their own market by bringing buyers and sellers together. Priceline operate as the middle man or broker bringing the two parties together in a seamless and friendly manner. Revenue is earned based on the difference between the â€Å"Name your own price† amount entered by the customer and the amount charged by the service provider such as the airline. A more traditional travel agency model is also used by them offering a list of prices the customer can choose from and in this case Priceline receives a commission/agents fee. Is the Priceline Model a sustainable one? ?During Priceline’s early start up days they experimented with variations of its business model by offering groceries and gasoline, which initially had negative impacts on profitability. However Priceline’s management was able to adapt and focus their model so that it started producing significant returns. ?Priceline improved from a $1 billion loss to a profit of over $10 million between the years of 1999 to 2003. Since 2003 Priceline has continued to be profitable and grow, increasing its stock price over 27 times from its lowest to slightly under $200 USD in 2010 and is now sporting a market valuation of $8. 8 billion. ? Additionally Priceline announced a ground breaking hotel price guarantee that pays customers a nominal reward if they find a lower price than the one offered by Priceline. ?As part of their expansion and growth they recently acquired the multinational car hire reservation service TravelJigsaw to provide more their value added services to their customers. Although the travel industry is saturated and has ever increasing competition, the population of the internet and those willing to buy goods and services over the web also continues to grow. Priceline Model- Changes Priceline has changed its business model since 2007 focusing more on traditional online reservation services. Customers have the flexibility to select from brand and features rather than their more restrictive an d discount â€Å"Name your own price† model. The Priceline website is now organized much like those of its competitors. Customers can still choose to bid, but this is no longer the only option. Value for money remains high, strengthened by elimination of booking fees, while service quality has improved. Priceline also continues to strive towards providing customers with a superior user-friendly service such as the launch in Jan 2009 of a The Travel Ekspert blog providing advice to consumers and also offering over 2. 5 million hotel reviews (PhoCusWright)

Ted Bundy Essays - Ted Bundy, Serial Killer, The Stranger Beside Me

Ted Bundy Essays - Ted Bundy, Serial Killer, The Stranger Beside Me Ted Bundy Ted Bundy Ted Bundy killed, raped and assaulted women all over the U.S, targeting young college women usually in Washington and Utah. His crimes remained anonymous, instilling fear throughout the country. Through a generally typical childhood and a successful education, no one would have ever expected Bundy to be a derailed monster. His escape skills and intelligence made it difficult to convict him but he eventually paid the price in 1989, in Railford's death penalty electric chair. Bundy fit the characteristics of an average young boy. He participated in the Boys Scouts of America ("Charles Montaldo"). His peers from school remember him as an intelligent, happy and popular child ("Predator"). So, what led to Bundy becoming an notorious killer? Maybe the peculiar confusion and anger his family caused him. His mother raised him to believe that she was his sister, and it remains obscure as to who his father might be. "Serial Killer Profile: Ted Bundy"). Bundy grew up in his grandparent's home, assuming that they were his biological parents (Predator"). He eventually discovered the truth behind the lies and grew extremely angry at his family ("Predator"). He looked up to his grandfather although, he was known for his turbulent temper and interest in pornography ("Predator").

Afterwards, when his hoax remained a success, he would rape and more than likely murder his victim ("Ted Bundy Biography"). Bundy murdered women at a frightening rate. His anonymous killing sprees horrified the country. In 1976, Bundy failed to pull over for a traffic routine stop his vehicle was then stopped and searched ("Charles Montaldo"). While the the patrol officer explored his car, he found a ski mask, a crowbar, handcuffs, and trash bags ("Charles Montaldo").

In a stolen van, he abducted twelve year old Kimberly Ann Leach in her school parking lot while she was dismissed by her teacher to retrieve a

Ytterbium Facts - Yb Element Facts

Ytterbium Facts - Yb Element Facts Ytterbium is element number 70 with an element symbol Yb. This silver-colored rare earth element is one of several elements discovered from ores from a quarry in Ytterby, Sweden. Here are interesting facts about element Yb, as well as a summary of key atomic data: Interesting Ytterbium Element Facts Like other rare earth elements, ytterbium isnt really all that rare, but it did take scientists a long time to figure out how to separate the rare earth elements from one another. During this time, it was rare to encounter them. Today, rare earths are common in everyday products, particularly in monitors and electronics.Ytterbium was one of the elements isolated from the mineral yttria. These elements derive their names from Ytterby (e.g., Yttrium, Ytterbium, Terbium, Erbium). For about 30 years, it was difficult to distinguish the elements from each other, so there was confusion about which element belonged to which name. Ytterbium went by at least four names, including ytterbium, ytterbia, erbia, and neoytterbia, when it wasnt altogether confused with another element.Credit for discovering ytterbium is shared between Jean-Charles Gallisard de Marignac, Lars Fredrik Nilson, and Georges Urbain, who identified the element over a period of several years, starting in 1787. Marignac repo rted the elemental analysis of a sample called erbia in 1878 (isolated from yttria), saying it consisted of two elements he called erbium and ytterbium. In 1879, Nilson announced Marignacs ytterbium was not a single element, but a mixture of two elements he called scandium and ytterbium. In 1907, Urbain announced Nilsons ytterbium was, in turn, a mixture of two elements, which he called ytterbium and lutetium. Relatively pure ytterbium was not isolated until 1937. A high purity specimen of the element wasnt made until 1953. Uses of ytterbium include use as a radiation source for x-ray machines. It is added to stainless steel to improve its mechanical properties. It may be added as a doping agent to fiber optic cable. It is used to make certain lasers.Ytterbium and its compounds are not normally found in the human body. They are estimated to be of low to moderate toxicity. However, ytterbium is stored and treated as if it were a highly toxic chemical. Part of the reason is that metallic ytterbium dust presents a fire hazard, evolving toxic fumes as it burns. A ytterbium fire can only be extinguished using a class D dry chemical fire extinguisher. Another risk from ytterbium is that it causes skin and eye irritation. Scientists believe some ytterbium compounds are teratogenic.Ytterbium is a bright, shiny silver metal that is ductile and malleable. The most common oxidation state of ytterbium is 3, but the 2 oxidation state also occurs (which is unusual for a lanthanide). It is more reactive than the other lanthanide elements, so it is generally stored in sealed containers to keep it from reacting with oxygen and water in air. The finely powdered metal will ignite in air. Ytterbium is the 44th most abundant element in the Earths crust. It is one of the more common rare earths, present at about 2.7 to 8 parts per million in the crust. It is common in the mineral monazite.7 natural isotopes of ytterbium occur, plus at least 27 radioactive isotopes have been observed. The most common isotope is ytterbium-174, which accounts for about 31.8 percent of the natural abundance of the element. The most stable radioisotope is ytterbium-169, which has a half-life of 32.0 days. Ytterbium also displays 12 meta states, with the most stable being ytterbium-169m, with a half life of 46 seconds.

Sickle Cell Transition Placement Essay Example | Topics and Well Written Essays - 2500 words

Sickle Cell Transition Placement - Essay Example According to Anon (2009) about 7 percent of patients often die due to the increase of liver iron, and other causes including strokes and infection are also considered causes of deaths among these patients. This essay will be a reflection of my sickle cell placement as a student nurse. This topic was chosen because I wanted to observe what sickle cell nurses do for patients in order to enhance my learning; moreover, I also believe that this learning associates well to my course. I also chose to observe what sickle cell nurses do for patients because I of the likelihood of encountering patients with sickle cell disease in the future. This essay shall first undertake a reflection on the transition activity; secondly, it will demonstrate a detailed knowledge of the transition activity, which in this case is sickle cell disease. This second part will also demonstrate the impact of the topic and the transition activity to my area of professional practice. This second portion shall also dis cuss the role of sickle cell nurses and shall then provide reasons why the activity was chosen. Thirdly, this essay will analyse how this transition activity has contributed to my own learning and skills development. Lastly, by focusing on this transition activity, this paper will also determine further areas for personal and professional development and how this might be taken forward through future research and further study as a registered nurse. In accordance with the requirements of the Nursing and Midwifery Council (2008), any personal confidential information regarding the patient/s and individuals involved in this placement shall not be disclosed. The Trust where I conducted my placement shall also be kept confidential. Body Reflection on the Transition Activity I had my transition placement on sickle cell disease, and initially during my placement, I had a discussion at the hospital with the patients and later visited them in their own homes. In general, the activities duri ng my placement were varied. I met with the multidisciplinary team regarding patients who suffered from sickle cell and how best to care for them. I also discussed the findings/results of the tests. I also observed how the sickle cell nurses administered care to the patients, addressing their needs physically, mentally, psychologically and emotionally. I also observed how nurses explained the disease to parents and their children, including the consequences of their illnesses as well as its risks/effects. I also observed how the nurses discussed with parents about the loss of their children, discussing with them the possible therapeutic options they can take as grieving parents. The transition activity initially provoked feelings of anxiety. However, in the process of learning, my anxiety soon vanished and I was able to transition gradually into the crucial duties of a sickle cell nurse. Duncan and DePew (2010) discuss that with more experience, the transition process among students of nursing can somehow be eased. In considering what I was able to get from this learning professionally, I was able to learn the qualities of the disease, including the specific role of the sickle cell nurse in ensuring efficient patient care. On a personal level, I was also able to get a specific feel for the nursing practice, including its

Micro Assignment Example | Topics and Well Written Essays - 500 words

Micro - Assignment Example This will result in an outward shift of the PPF curve. 2) The reason why countries such as Costa Rica and Bangladesh are better placed to produce shirts and then export them to the United States is because of their competitive advantage, not an absolute advantage. Let’s use Vietnam as an example. The wages that have to be paid to Vietnamese workers are far less than those that would be expected by American workers. This means that it is better for America to import goods such as shirts from third-world countries because it can be produced far cheaper. Even with the added costs of transportation, this option is still better than America producing the goods domestically. So even though the United States has an absolute advantage in almost every good, it makes logical sense for them to outsource work that can be done cheaper somewhere else. 3) The reason why countries such as China and India use manual laborers is because it is cost effective to do this in those countries. Also, these countries may not have the same technological expertise to produce machines to do the work for them. Even if this is the case, the average wage is so low that it does not cost very much to pay for human workers. On the other hand, in the United States, the minimum wage is so great that is would be too expensive to have to pay individual laborers to perform the work. Also, the United States is a technologically advanced country and can thus produce street cleaning machines to do the work. The total cost of making and using these machines is probably less than what it would be to have to pay manual laborers; thus it makes sense to use heavy street cleaning machines. 4) The reason why there is so much opposition to international trade is that some people argue that it hurts the local economy because of the loss of jobs for home workers. While international trade can be a good thing for the

Summary of Chapter, Pricing Strategy Assignment Example | Topics and Well Written Essays - 500 words - 5

Summary of Chapter, Pricing Strategy - Assignment Example The percentage of profit that company deems fit is added to set the final cost. The cost price strategy becomes viable for product only when defined sale volumes are estimated and met through effective marketing. This is a flawed strategy as it relies on sales volumes and if they are not met, the cost goes up and adversely impacts the performance of the company. It also totally ignores the customers who are increasingly become the major part of business strategy and marketing. Competitor based pricing primarily believes in the price strategy of its main competitor and follows the same regardless of its repercussion on its profitability. This is wrong because each has its own constraints and inputs that need to be considered in the pricing strategy. It becomes fatal when the competitor’s strategy is based on selling the product irrespective of loss. The market-led strategy is best described by setting one’s pricing based on the pricing of its competitors. The pricing is either the same or lowered so that to gain market position. Sometimes, when value addition to the product provides it with unique features, firms can maintain their market position even when the price is raised. This is most prevalent in the contemporary environment of high competition. Glaxo’s Zantac had overtaken SmithKline Beecham’s Tagamet because it had fewer side effects in ulcer treatment. Thus, product pricing also influences customer’s perceived value of the product. Three techniques: tradeoff analysis; experimentation; and economic value to the customer or EVC are used for understanding customers’ perceived value of the products. The tradeoff analysis uses customer’s requirements for a product and adds or removes those properties within the product to make it attractive to the customers. Firms can raise the price despite heavy competition. Experimentation  tests the preferences of customers by placing the same product with varying prices at a different location.  

Concept Analysis Research Paper Example | Topics and Well Written Essays - 1500 words

Concept Analysis - Research Paper Example These instructions provide patients with critical information on how to manage themselves in terms of medication, diet and which symptoms should prompt the patient to return back (Lee & Bokovoy, 2005). Issuing of discharge instructions to patients is a key requirement of health care facilities by the health accreditation institutions such as the Joint Commission on Accreditation of Healthcare Organizations-JCAHO (JCAHO, 2007). Despite holding to this requirement, it is widely reported that patients fail to comprehend or remember the discharge instructions. This is contributed by both parties: practitioners failing to elaborate clearly the instructions and patients failing to follow the instructions. This paper is a concept of comprehension that focuses on discharge instructions and how patient’s comprehension of these instructions affects their outcome. Concept of Comprehension on Discharge Instructions Discharge instructions refer to instructions given to patients upon discha rge from hospital. These instructions detail diagnostic information and measures to be taken. As noted by Forster et al. (2004) close to a quarter of patients discharged experienced adverse cases in a span of one month. These events were medication errors, orders/prescriptions filling, confusing discharge instructions, neglect of following unresolved cases and infections. Some of these effects were preventable whereas others called for further treatment probably half of the effects. Moreover, Forster et al asserted that a third of the events were linked with disability (Forster et al., 2004). According to Zavala et al. (2011) 78 percent of discharged patients from emergency department failed to fully comprehend the discharge instructions. However, 20 percent acknowledged they did not understand the discharge instructions. This was achieved from a study conducted in a healthcare facility in Virginia, Reston Hospital Center. This study focused to reach the discharged patients from the facility in order to get their understanding of discharge instructions and its effect. A fifth of the patients interviewed did not understand the discharge instructions based on the medicine described. Additional 9 patients reported worsened and continued symptoms where they were reminded to follow up treatment. A few patients reported their discomfort about the discharge instructions and some did not receive the discharge instructions (Zavala et al., 2011). Understanding as well as memorizing discharge instructions is very challenging. This is associated with several aspects such as discomfort and literacy levels. Relative to discomfort, patients and their surrogates are filled with various discomforts emotionally and physically. More specifically, patients and their surrogates are filled with excitement of leaving hospital. This carries away their attention and thus they are less concerned about the discharge instructions. Additionally, the busy hospital environment during discha rge also causes discomfort to the patient/patient surrogates and distracts their attention to discharge instruction. In such a situation, the busy physicians assume patients understand the instructions and to further complement this health brochures are given. Majority of patients obtain and understand little of these information from the health brochures. This creates great disparity between the reading and literacy level

Summarizing an Article - Essay Example Three different research questions were taken into consideration. In the first hypothesis, the authors made an assumption that the acceptance from partner was due to different reasons and had an association with some elements either positive or negative; Either the fact relates positively with the effectiveness of the participants weight management communication or secondly the participant’s satisfaction is positively associated with their conversations regarding weight management. In another assumption a negative association was predicted with the participant’s conflict regarding weight management. While the second last and last assumption had a positive relationship with the participant’s healthy eating habits and their amount of exercise (Dailey, Romo and Thompson). In the second hypothesis the challenge from partner was considered (1) to have a positive relationship with the effectiveness of participant’s weight management communication, (2) to be posi tively associated with participant’s satisfactions regarding conversations on weight management, (3) to have a negative relationship with participant’s conflict regarding management of weight, (4) to be positively associated with healthy eating habits of participants, and (5) to have a positive association with the amount of exercise participants perform (Dailey, Romo and Thompson). ... agement conflict, (4) healthy eating habits, and (5) duration of exercise in a way that it should illustrate the relationship between one element and its results which will rise with raised levels of second element (Dailey, Romo and Thompson). All the three hypothesis assumed three different questions however, all three were aligned with each other. B- Methodology / Approach / Sampling: For this research methodology the researchers have adopted the quantitative method. The researchers have selected a normative sample of 200 adults. The sample was adequately divided into 50% males and 50% females. The 100 couples were selected through proper recruitment approach in a Southwestern area of United States. The recruitment was done through proper advertisements in websites, and through flyers at gyms, coffee shops, and local health clubs. Questionnaires were given to the couples and a duration of 60 – 65 minutes were given to them to complete the survey. The data was collected throu gh conversations between the couples regarding health and weight management. The data gathered through the conversations were assessed through a measure adapted from Hecht. However, 7- points Likert scale was also used to assess the elements of research. There are two controlled variables used in the research by the researchers; how often the partners have had conversations regarding weight management and to what extent they wanted to stay healthy and how significant was health to them (Dailey, Romo and Thompson). C- Results / Findings: The results obtained were tested through APIM. The method was used to answer the degree of interdependence between partners in couples regarding weight management. However, multi-level modeling was also used to assess the results. However, MLM were significantly

Walmart Case Essay Example for Free

Walmart Case Essay Walmart has thrived in a very competitive industry by building on its founding principles and developing arguably the industries best supply chain. It has integrated its sales to its suppliers, streamlined order fulfillment and driven down its costs, which is one of its key founding principles, â€Å"Our purpose is helping our customers save money so they can live better† (Grant text, 5 walmart core 5 values). Walmart has had great success in North America, but its cultural values have not translated well in other parts of the world. Great sales growth has not translated into significant margins. Walmart has incurred losses on its international operations. Carrefour (founded in France) and Walmart both retreated from Germany. Some of the key issues facing Walmart include adapting their founding 5 core principles to vastly different cultures; the drive to cut costs clashes with treating the employees as part of family (which part of the family has more value? Is treated with integrity? ); the drive to cut costs has been driven far down the supply chain to a myriad of suppliers, sub-suppliers and sub-sub-sub suppliers†¦. how can Walmart audit or control these suppliers†¦standards imposed by Walmart? Current Situation Brief History Walmart has grown over the past 50 years from a local ‘general merchandiser’ with 15 stores in Arkansas to become the largest in the world with over 10,000 stores world-wide. Wal-Mart’s six market segments are: groceries; fashion clothes; pharmacy; health clinics; financial services; and music downloads. Its main North American competitors are Target, Dollar General and Costco. Walmart has four formats plus on-line that it has adapted to its international expansion. These formats have not always been successful, especially in their foreign expansion with retreats in Germany, South Korea and losses in Japan. The formats are: The smallest are neighbourhood formats averaging 42,000 square feet Traditional Discount store averaging 102,000 square feet Sam’s Clubs averaging 127,000 square feet Super Centers averaging 187,000 square feet No matter who we are or where we come from, our values pull us together and keep us together. They constantly push us forward to become a better and stronger company. Mike Duke, Walmart President CEO Sam Walton drove this growth founded on five(5) core principles with its roots in small town US family values: Integrity: Be Trustworthy and honest in all your business activities (Sam valued Honor) Opportunity: If, you work hard and do a good job, you will be promoted (approx.. 75% of store managers started as associates) Family and Community: Your customers, suppliers and associates are your neighbours. Work with a purpose: Deliver them the lowest costs (EDLP) and their lives will be improved. Responsibility: Make the world a better place These became Wal-Mart Stores 3 core values: The Value Statement: Service to the customer, Respect for the individual and Striving for excellence. From the website: Delivering a seamless shopping experience; Talent is key to success; Benefiting our communities. The Mission Statement: Save Money/Live Better (from the website). There is consistency in Sam’s values and Walmart’s stated values today. Walmart built its US operations using a hub and spoke system. The hub (distribution center) supports the spokes (stores). Each wheel was the launch board to the next hub and spoke as a hub could support growth of sufficient stores to build a new hub. Today Walmart has expanded overseas primarily through joint ventures or acquisitions and then built wheels to support the new regions. Additional distribution models such as Remix and the integration of IT systems have been built to streamline ordering, deliveries and drive costs further down the supply chain. Expansion overseas and growth have impacted margins, at least in the international operations, and affected the ability to centrally control the operations and keep the personal relationships between head office and the individual store managers. Porters 5 forces the resource based approach (C. K. Prahad Core Competencies) to firm analysis The External Environment Porters 5 forces can be termed the outside-in approach to industry and firm analysis. The general merchandising industry is very competitive with few to no barriers to entry, buyers can easily switch among many substitute products with cost becoming the primary factor of choice for buyers. The only strength for a merchandiser is the choice among many suppliers. Barriers to new entrants (Low) Few to none Location and min financing Power of Suppliers (HIGH) Little power; many substitutes Power of Buyers (HIGH) Many alternatives; can price compare; customer service is of minimal concern Substitutes (Low) Most products have many substitutes Industry Competitors Intense rivalry; no obvious barriers to entry; suppliers have little power; the only avenue for uniqueness is internal competencies Based on the porters 5 forces analysis, we found the general merchandise industry is not attractive. We need to use a different model to assess Wal-Marts’s competitive advantage The real competitive advantage for any firm is how it uses its resources, but more importantly its capabilities to create competitive advantages over its rivals. The resource based view as â€Å"popularized by C. K. Prahad†¦. ’The Core Competence of the Corporation† will be used to evaluate Wal-Marts core competencies and its ability to leverage these competencies to create a sustained competitive advantage. Walmart’s Resources and capabilities (The internal environment) Tangible resources: 22-24% debt to total assets has remained stable; ability to borrow Their working capital has remained steady at 0. 9 to 1; pay bills as they come due Major investment in fixed assets at 56-58%; stores and fixtures to support sales growth US Super centres: 3022; 629 US discount stores (declining numbers); 611 US Sam’sclubs; 196 US Neibourhood Markets; 5651 International units†¦lots of stores 23% ROE will allow Wal-Mart to easily raise funds in the equity markets Walmart’s financial strength allows it to finance growth without increasing its leverage. Its debt to equity and working capital has remained stable over the past 10 years with little impact from the financial crisis. This, in combination with the industry’s highest return on equity, means Wal-Mart can borrow at a very low weighted (WACC) average cost of capital (interest costs have averaged less than 5% of long-term debt) or raise capital in the stock market at favorable prices. Its major investments are in inventory and fixed assets. The fixed assets are supported by 93% long-term debt and equity financing meaning part of working capital is supported by long-term financing. This is a conservative approach and explains why Wal-Mart was not greatly impacted by the credit crunch brought about by the financial crisis. Intangible resources Founding 5 core principles: small town values; EDLP; community; responsibility; opportunity Proprietary distribution sw systems- satellite RDFI for logistics mgmtand inventory control Links all stores, to system all the way to suppliers; tracks items Own their own satellite; use EDI with suppliers; POS to suppliers for inventory reorders Store layout Growth through Hub and spoke (distribution) system Cross-docking system: minimal warehousing; goods go immediately from dist pts to stores; minimizes costs Customer satisfaction guarantee program; use of greeters EDLP Decentralized store management: layout,pricing, sales strat by dept mgrs. , product mix within store Use of IT to integrate entire value chain Communication and supervision structure keeps stores close to HO Reg VP? 10-15 Dist Mgrs ? 8-12 stores; VP visit stores/no offices; data accum M-th; data anal Fri-sat; decision made Sat; Dist mgrs. Contacted sat for following week Wal-Mart’s founding principles as enshrined in its mission and vision give’s every associate right up to the management team a focus and an understanding of where each component of the value chain. fits in this picture and where each of their jobs and duties lie. There is no doubt, nor is there any drift. Each job has a purpose within Sam’s greater vision. Greeting the customer or stocking what is in demand is all part of the â€Å"Customer Satisfaction Guarantee†. The distribution (RDFI), purchasing (EDI) and sales (POS) systems have been integrated in order to control costs at all parts of the value chain. In effect driving costs back to the suppliers. This singular focus on cost has allowed Wal-Mart to pass this savings to its customers. This has been facilitated by minimizing bottle-necks using cross-docking and REMIX and growth with the hub and spoke strategy including regional mega distribution centers such as Shanghai China to support global growth. Decision making at the customer level has been decentralized to the store level allowing store managers and department managers control over layout, input on pricing and products on the shelf. This allows for EDLP (everyday low pricing) to be competitive at the local level in all regions. The weekly meeting is a hallmark of Wal-Mart. It has been changed to monthly, but the weekly gathering of information to facilitate decisions from the corporate to store level remains. The VPs meet with their district managers who visit all their assigned store managers (stores) gathering the intelligence needed to drive the strategy and the tactics. This information is culled to develop ongoing strategies from supplier acquisition or termination to individual store strategies all to facilitate â€Å"Save more, Live better†. Human Resources Empowered sales associates 94% of employees have health benefits With one year or more of service employees are covered by a pension Pay scale is higher than competitors All store managers from around the world participate in a monthly meeting via satellite (formerly the famous Wal-Mart weekly meetings) Wal-Mart’s employees (or associates) are family. They are your neighbours. Associates are empowered and when deserved, promoted . They are given better than average health benefits and wages. All associates are covered by a pension plan. Associates will someday become the VP’s, district managers and managers. They are Sam’s community to be treated with honour and respect, just the same as the clients.

Joan Of Arc Essay -- Biography Biographies Joan of Arc Essays

A French saint and a heroine in the Hundred Years' war was Joan of Arc. This farm girl helped save the French from English command and was often called the Maid Orleans and the Maid of France. Her inspiration led the French to many victories. Joan Of Arc (In French Jeanne d'Arc) was born around 1412, in the village of Domremy, France. She was a peasant girl who, like many girls of that time, could not read or write. Her father, Jacques, was a wealthy tenant farmer and her mother, Isabelle Romee, taught her how to sow, spin, and cook which she was proud of. She also spent much of her time praying to and serving God. She lived like most children did at that time, until when she was about thirteen. According to Wagenknecht: "The Vision first came when she was first thirteen...." 1 The vision was Saint Michael who said she should be a good girl and go to church. When more and more Visions had come it started coming clearer to her and when she saw Saint Catherine and Saint Margaret her duty was clear, she was the chosen one to crown Charles the VII. 2 Since France had been fighting with England in what was called the Hundred Years' War, much of Northern France was captured by the English, including Reims where the coronation for kings had been held for over centuries before him. Since Reims was captured, Charles the VII, who had not yet been crowned; was still called the Dauphin. When Joan had these visions of Saint Catherine and Saint Margaret, she told her family and friends. When she told her father, he would not let her go. After when these Visions told her that England and Burgundy, England's ally, were going to capture Orleans, one of France's last strong forces, she knew she had to react. She needed to go to the governor of Vaucouleurs, an agent of the Dauphin, and convince him to give her an army to escort her to the Dauphin. She first needed an escort to come with her to see the governor so she asked her cousin, Durand Laxart. He, at first, was skeptical about it, but then he soon came to Joan's side. When she told the governor, Robert de Baudricourt, he said she was a fool and she should go home. But after some time of waiting, Baudri-court let her go, under his protection, to the Dauphin with male clothing, a sword, 3 a safe conduct pass, and a small escort. They departed February 23. They safel... ...tried as a witch under an ecclesiastical court. She was handed over to Pierre Cauchon, bishop of Beauvais, on January 3rd, 1431. The sittings had begun on February 21 and continued over a period of months. She was held in chains, harassed by countless questions, and threatened with torture over this period of months; Saint Catherine and Saint Margaret still gave her advice through all this. On May 24, 1431, Joan was taken to the cemetery where she she was to been burned at the stake unless she recanted, which she did. This is not really to clear to historians why she did that, but many believe that she did not understand what the recant meant. Wagenknecht stated that "Her own view, after she was herself again, or perhaps one should say her report and interpretation of the view of her Voices in that matter, was that she had imperiled her soul to save her life: 'It was the fear of the fire which made me say what I did." 7 After her recanting she was sentenced from death to life of imprisonment. Of her being treated so softly, the English were furious. Joan had thought she was going 10 to be sent free but instead Cauchon sentenced her to perpetual imprisonment.

Julius Caesar :: essays research papers

Based on his thoughts and actions, how would you describe Caesar? In Act II Julius Caesar is barraged with warnings to stay home and not go to the Senate, but he ignores them. Calpurnia, his spouse, tells of a dream she had and fears for Caesar's safety. The priests also warn Caesar. However, Decius is able to persuade Caesar to go to the Senate that morning. Considering his actions and thoughts in Act II, Caesar is a ruler who rejects superstitions and is concerned about how he is perceived by others. As scene 2 opens, there is a thunder storm that sets an eerie tone. Calpurnia reveals her dream to Caesar and expresses concern for his safety. She then warns Caesar to stay home. Julius replies that the work of the mighty gods can not be avoided. He also contends that death is inescapable and therefore he will go to the Senate. His servant thereupon returns with the news that the priests likewise warn Caesar not to go out that morning. Caesar also discards the advice of the priests and asserts his bravery and superiority over others. Eventually, Calpurnia persuades him to stay at home. This shows Caesar as a man who is willing to set aside his priorities to please his wife. Once Decius enters Julius is content to stay home. However, Decius manipulates Calpurnia's dream into a positive one and starts to question Caesar's manhood and power because he is afraid of the hallucinations of his wife. Caesar is now afraid and concerned of what the senators will think of him and fears that will see him as weak. This convinces Caesar to dismiss the warnings of his wife and the priests and go to the Senate. From his statements Caesar first concedes to his wife but once his considers the thoughts of others about him he decides to 'save face' and attend the senate. Compare and contrast the motives that Brutus and Cassius have for wanting to kill Caesar. Brutus and Cassius, both conspirators against Caesar both have dramatically different views on the reasons why Caesar should be assassinated. Brutus is a main of morals, reason and honor while Cassius is deceitful and manipulative. Brutus seeks to glorify Rome and avoid tyranny by assassinating Caesar. Cassius wants to destroy his enemy and severely dislikes being under the control of a tyrant. As leaders in the Senate, Brutus and Cassius confederate to assassinate

Hunter V Moss Criticisms

Certainty of subject matter and the critcisms of hunter v moss When creating an express trust knight and knight articulated that there must be certainty of subject matter, certainty of intention and certainty of objects. Certainty of subject matter is where there must be an identification of the trust property and certainty as to whom is which part of the trust property to be held. In relation to uncertainty of beneficial interests, the trust will fail where the method of distribution is stipulated by the sethlow but cannot take effect (Boyce v Boyce).However the trust will not fail where the method of distribution is not stipulated by the sethlow leaving the court to intervene (re napton). If there is an effect of lack of certainty in respect of the beneficial interests in the trust property a resulting trust will be imposed because equity hates a vacuum, the trust property will therefore be held on trust for the sethlow or if he is dead for his estate.In regards to identification o f the trust property If there is a lack of a proper identification of the trust property, the trust will fail because the property never leaves the sethlow and there is no need for a resulting trust. However the term residue estate will not fail a trust because it means all the remaining trust property. It is quantifiable A problem occurs where the wording used is not sufficiently certain as to know what property is intended to be held on trust and where the property that is held on trust is not segregated by the sethlow from a larger amount of similar property he owns. If a trust fund is not segregated then there will be no certainty of subject matter and the trust will fail. The problem is identifying the property that constitutes the trust fund. The property must be identifiable otherwise the courts would not know which property is to be distributed to the beneficiaries. It must be shown that the sethlow intended to create a trust over specified property. In Palmer v Simmons â₠¬Ëœthe bulk of her estate’ was not sufficiently certain and ‘remaining part of what is left’ also (sprange v barnard).However in Re Golay the court looked at the tester’s intention’. To deduce what ‘reasonable income’ meant Oliver J articulated the orthodox approach or rule in re London wine where property must be segregated form a lager mass of similar property for there to be a valid trust he said â€Å"To create a trust it must be possible to ascertain with certainty not only what the interest of the beneficiary is to be but to what property it is to attach. â€Å"The ‘mere declaration that a given number of animals out of the flock would be held on trust would not create a trust’. This approach was followed in re Goldcorp which affirmed that property must be separately identifiable before it can be held on a valid trust. The contention arose with Hunter v Moss which did not follow the orthodox approach where Hunter wa s entitled 50 out of moss’s 1000 shares. Under the Goldcorp rule there would be no trust because the property was not separated however Dillon J said there was a valid trust.The rationale for this controversial decision was that it would have made no difference which 50 shares would have been given because they were all identical. So here there was no need to segregate the property if it was intangible. The problem with this case is that Dillon is giving the trustee of the will who only has legal title subject to the terms of the trust an executor status, i. e. putting him in the shoes of the sethlow.This is a problem because the executor acquires legal title in all of the deceased’s person’s property with a power to make a division of property in accordance with the terms of the will as personal representative of the deceased. Whereas the inter vivos trustee makes a division subject to the terms of the trust. So inter vivos trustee cannot know what property fal ls under his remit whereas the executor knows that he has title in the whole property formally vested in the testator so there is no uncertainty of subject matter.Dillon did not make a distinction between tangible and intangible property. But did say that â€Å"the London wine case concerned chattels and this case concerned a title over shares† This case has been applied in Holland v Newbury where the securities were intangible property and therefore did not require segregation. This may mean that Hunter v Moss is precedent because it was resolved in the C of A whereas Goldcorp was decided in the Privy Council and can only be deemed a persuasive authority.However the earlier case of MacJordan v Brookemount may have supported Dillon because the judge thought it was not necessary to segregate part of the bank account from a larger amount of money in the same account. However here there was no identifiable bank account in the first place to establish a trust so it was void. Othe r problems with Hunter v Moss is that it ignores traditional property law which requires there to be specific and identifiable property which is the subject to a trust. There was only a valid trust because there were ufficient shares to satisfy the claim. The C of A could not have decided this in Goldcorp because there were more claims than there was property to satisfy them. If there was a distinction to be made between cases in which it would be valid to hold one trust valid despite insufficient segregation and another trust invalid on grounds of insufficient segregation it would not be based on whether the property was tangible or intangible but rather whether the legal owner of that property was solvent or insolvent which in Goldcorp he was insolvent..So it seems Dillon lj's reasoning is ill founded. Another problem is that why should there be a specific rule for intangible property. Tangible property could be subject to the same rules. In Caswell v Powell â€Å"bushels of whea t are indistinguishable† and that in relation to a 1000 ball bearings it does not matter if 500 were separated because they would be all the same. So the distinction based on tangible and intangible property is weak and that it would be better to base a distinction on whether the trustee was solvent or insolvent.The reaction to Hunter v Moss has been mixed Alistair Hudson says that â€Å"Hunter v Moss is concerned with achieving justice between the parties†. Because Goldcorp concerned the allocation of property whereas HAUNTER V Moss the court was concerned with preventing the employer from benefiting from a breach of contract. However David Hayton argues that Dillon’s judgment may well come to be stigmatised as determined perilously close to vacation.He highlights questions left open by hunter v Moss Because, Moss declared himself trustee of 50 of his shares, an obvious problem arises because there is no certainty as to which 50 of the 950 shares the trust relat es. Thus, if Moss subsequently sells 50 shares how do the Revenue know whether he is selling his own shares, so that he is chargeable to capital gains tax, or if he is selling Hunter's shares so that Hunter is so chargeable?If the proceeds of sale are profitably or detrimentally reinvested does the new investment belong in equity to Hunter or Moss, bearing in mind that it is only if Moss is acting wrongfully in respect of specific shares that Hunter can take advantage of the equitable tracing rules to apply whichever of them suits him best? Can Hunter obtain an injunction to prevent Moss selling or mortgaging any shares or only more than 900 shares? Does Hunter really have any specific proprietary interest capable of assignment?Despite these criticisms Jill Martin says that Hunter v Moss appears fair, sensible and workable also Allison Jones says the decision is a sensible one. She says it seems absurd that there could be a valid trust of the entire contents of a bank account which could then be traced wrongly into another account of the trustee but that there cannot be a valid trust of part of the funds in an account. But even Therese Villiers says that â€Å"the flexibility provided by Hunter v. Moss may yet prove to have deleterious effects† Hancock v Watson exception?

Comparing Evidence of Both Norse and African Presence

In pre- Columbian America there is evidence to show that there were both Norse and African presence present before the arrival of Christopher Columbus’ maiden voyage in 1492. The presence of the Africans was first stated by Christopher Columbus himself in his voyage diaries, which he claimed was told to him by an Indian on his second voyage. This was later solidified by Portuguese seamen who also told of African navigation to Columbus. On the other hand the Nordic Movement into pre- Columbian America was stimulated by the adventurous and nomadic nature of the Norsemen.The men hailed from Northern Britain, Scandinavia, Northern Germany and the Netherlands. They were also known as Northman which was interchangeable with the term ‘Viking’. This essay will assess the botanical, archaeological and oceanography evidence along with the African and Egyptian Cultural history of the African presence along with the botanical, metallurgical, archaeological, cartographical, or al and written evidence of the Nordic presence in the pre- Columbian America.To prove that African presence existed in pre-Colombian America before Columbus’ arrival Professor Van Sertima presented archaeological evidence in many forms. The first piece of archaeological evidence was the Guanine. The Italian account Raccolta of the voyages reads â€Å"there were pieces of gua-nin as large as carvel’s poop. †1 This alloy existed predominantly with Africans who were outside of the Atlantic World. It was generally found on the tips of spears and other weapons making this an important component for the indigenous societies.The trading of this alloy was extensive between the Africans and the Indigenous people. â€Å"†¦ and he (Columbus) wanted to find out what the Indians of Hispaniola had told him, that there had come to it from the south and southwest Negro people, who brought those spear points made of a metal which they called guanine, of which he had sent t o the king and queen for assaying, and which was found to have thirty two arts, eighteen of gold, six of silver, and eight of copper. † – Raccolta, PARTE , VOL. This piece of archaeological evidence helps Van Sertima to show that before Columbus arrived there was interaction between the Africans and the people of the Atlantic World via the form of trade. â€Å"The Negroid element is well proven by the large Olmec stone monuments as well as the terracotta items and therefore cannot be excluded from the pre-Columbian history of the Americas. †- ALEXANDER VON WUTHENAU2. The most important of all the archaeological findings of African presence were that of the Negroid Olmec heads found in La Venta, Tres Zapotes and San Lorenzo, between the period of 1939-1940.This piece of evidence was the most concrete of all that Van Sertima collected to explain pre-Columbian African contact. These were large carved stone heads reaching six to nine feet high, weighing up to forty t ons each3 and were carved out of basalt stone. When they were unearthed in both central and south America it was declared by Van Sertima â€Å"There is no denying their negroness either, the features are not only nergo African in type but individual in their facial particulars cancelling out the possibility of ritual stereotypes of an unknown race produced by some quirk of the sculptor’s imagination. Not only did these heads have the facial features of that of an African but on one of the stone heads dug up was found to have Ethiopian braids These Olmec heads were the most convincing pieces of evidence of African presence in the pre-Columbian presence that Van Sertima presented in his theory.As much as archaeological evidence is important so is oral history and traditions, as quoted â€Å"We are vessels of speech, we are the repositories which harbour secrets many centuries old without us the names of kings would vanish from oblivion, we are the memory of mankind; by the sp oken word we bring to life the deeds and exploits of kings of younger generations†4. There are oral records within African societies giving parallel accounts and evidence to substantiate the findings presented in Van Sertima’s theory. The story of king Abubakari of the ancient Mali kingdom was passed down orally from generation to generations.King Abubakari set sail in 1311 with a well equipped naval fleet to cross the Atlantic although he failed within the evidence that is presented now of his arrival around the time that links African presence in south America. It also highlights the fact that it was more than just a mere coincidence thus showing a direct link and connection between two civilizations. Professor Van Sertima also present evidence in oceanography to verify historical reports and accounts the journey from West Africa to the Americas was possible.Geographical research shows that there are three major current off the coast of Africa leading automatically to the Americas. Perhaps Heyerdahl’s greatest contribution has been shown by example that long voyages in â€Å"primitive† craft were not impossible. This may have been necessary for some Amercanists; it was not for those who knew the sea5. Thor Heyerdahl; a Norwegian writer and explorer made more than an academic study of these ships used. Heyerdahl put the ship building ideas and designs of the ancient Egyptians to a practical test to make it across the Atlantic to the Americas from Africa.Using the most primitive of the boats; built from the papyrus reed Heyerdahl conducted two experiments with the vessels Ra and Ra which visualized the Trans Atlantic Current. The Ra set out from Safi, on the Atlantic coast of North Africa, on May 25, 1969. It sailed to within a few days of the New World before it got into serious trouble. The Heyerdahl expedition had made one mistake†¦ A smaller model, Ra, built on the identical Egyptian pattern†¦ made it across the Atlanti c from Africa successfully6.This experiment proved to be successful crediting the theory that the Africans may have used the sea route to reach the Atlantic World. The adoption of a new plant is no simple matter. It requires the adoption of a whole complex of knowledge about the plant’s ecological requirements, and often also about the human usage of the plant. The presence of even one transferred plant means that a quite effective contact has been made between two people7. In traditional Africa their main form of currency was the use of shells and cocoa beans as currency rather than other symbolic items.This factor could be seen translated in the currency of the Mesoamericans as Botanical continuities was presented by the presence of African species found in the Americas for example the Jack bean is believed to be a crop of African origin that was brought to the Americans before Columbus’ arrival, West African yam has also been found in the America additionally other plants that became a major aspect of the Atlantic World such as banana and maize hints towards African cultural influences in the region. On the other hand now there is the theory that the Vikings were here before Columbus as well.The most prominent source of evidence of pre-Columbian Viking contact with the New World can be found in the Icelandic Annals (chronicles): Islending book, Flateyjar book and Landnama book. Evidently this area which is now the home of the copper Eskimo and other Eskimo, was occupied by the Eskimos in Viking times, for its Icelandic name of the map is Einjoetingidand (Land of the Einfoeting). The story of Einfoeting related in the Icelandic saga of Rarlsefni is declared by Godfrey to be â€Å"wholly impossible. †8 Initially these sagas were passed on orally until Adam of Brehemin also known as Adamus Brenamus of Cleric began transcribing these tories in 1070. These sagas made special reference to the New World described are generally termed ‘Vi nland’ but are found in sections of the Greenlanders saga and Erik â€Å"the Red†. The sagas documented the arrival to three territories: Helluland (flat), Markland (timber) and Vinland (grapes), which were taken to be now Baffin Island, Labrador and Newfoundland in Canada. Correspondence with Newfoundland officials, Lloyd’s explorations in 1873, and preliminary explorations for the author by Alf Budden of Sops Arm, Newfoundland, in 1940 indicated that the Sops Arm area was the site of the first Norse settlement in Vinland9.Most important of these places mentioned in the sagas seemed to have been Vinland as several expeditions were taken to that place. Some of the expeditions were taken by: Lief Erikson, Thorvald Erikson, Thorstein Erikson, Thorfin Karlefin, Freydis Erikson. It was wildly believed that is now present day L’Anse aux Meadows. Other than their sagas the Vikings had more concrete evidence in cartography and mapmaking. The interpretation of th e Viking charts by the author has been verified by the Hydrographic Office of the U. S. Navy10.A world map adated about 1440 was found in 1965, this map clearly showed locations of Vinland. It was found in a book called the Vinland map and â€Å"Tartar relation†. Irrefutable evidence of the Vikings’ discoveries in America is their navigation charts. These were marked in Old Icelandic the names they gave to the areas they discovered. Showing coasts and waterways of ancient America, they belong to a series of more than 35 maps of the ancient world which have been preserved for thousands of years in various parts of the Old World11.We can conclude from this that this piece of evidence supported the theory of Viking presence in pre-Columbian America. â€Å"Two iron shovels were found, one in an Enkieling furnace and one in a hearth-pit furnaces . A. M. Hall, metallurgist of the Battelle Memorial Institute, examined these shovels and reported that they had been made by cla dding two carburized iron sheets together†12. Evidence of Norse style smelting was uncovered at an excavation site in L’Anse aux Meadows. Iron manufacturing was an activity where bogore, which was a form of iron from which bogs was processed in order to make boat nails.This need for boats nails explains the introduction for iron smelting in the Americas. â€Å"Two Enkielings of the pit type, two of the above ground type, and ten hearth-pit furnaces were excavated in the Deer Creek Valley. There were three kinds of hearth-pit furnaces, all types that were used in the Old World before the fourteenth centurary†13. This piece of evidence solidifies the theory of the Vikings’ presence. During the excavation at the site in L’Anse aux Meadows, the Norwegian explorer; Helge Ingstads, found remnants of a Viking settlement in L’Anse aux Meadows in 1960.This was founded in the province of Newfoundland in Canada along with butternut; three to be exact, t hat were preserved. More importantly these bogs found contained tanic acid which can preserve both organic and inorganic materials for centuries. The presence of these butternuts suggests that they were transported to the area rather than grown there. This adds more value to the pre-Columbian Nordic presence theory. Also a burl which is a roundish, warty outgrowth from the trunk and roots of certain trees of butternut wood was also found in the bog.Thus it can be safely concluded that Vikings brought this wood with them. Similarly items made with Scott’s pine also known as pinus Sylvertris were found in the bog. Again this type of wood did not grow in that area and it was common for utensils to be made from it in the Old World. The most impressive evidence of Vikings in the New World comes from L’Anse aux Meadows on the northern tip of Newfoundland. In 1960 most of the archaeological evidence was gathered there from excavation by Ingstad. The Ingstads found a Norse sit e one hundred metres from the ocean shore comprising of three complexes.All the buildings were located on a narrow beach terries surrounding a sedge peat bog and a wet sphagnum bog. These houses have usually been circular; if they were rectangular, their width was only slightly less than their length14. The early Scandinavians up to the 12th century lived in dwellings which were different from all other communal houses in the old World because they were long, narrow, one room, one story buildings with two passage ways and a long central hearth extending lengthwise through the building.The only lighting came from the fire on the hearth and through openings left in the roof to permit smoke to escape15. The buildings were made from a timber frame covered in sod and the roofs were steeply peaked. Some items found at this site that were preserved in the bog included wood shavings and chips from the carpentry shop, items of broken wood, tree nails which were used in their ship building, p lank patch for cracked boat stakes, a bow for an auger and pieces of rope made from spruce roots. Also a Viking coin was found at the Goddard site dating to A.D. 1070. The coin was the only Norse artefact found. I t was also determined to be in this place16 because of trade between the Vikings and Native Americans17. In conclusion it can be noted that from all the evidence put forward of both Norse and African presence in the pre-Columbian Americas some out weight the other in being concrete historical evidence. However it can be said that due to all this evidence it can be stated that there was interaction between both groups and the indigenous peoples before the arrival of the Europeans.Sources 1.

Experiment on polytropic process Essay

Polytropic Expansion of Air Object The object of this experiment is to find the relation between pressure and volume for the expansion of air in a pressure vessel – this expansion is a thermodynamic process. Introduction The expansion or compression of a gas can be described by the polytropic relation , where p is pressure, v is specific volume, c is a constant and the exponent n depends on the thermodynamic process. In our experiment compressed air in a steel pressure vessel is discharged to the atmosphere while the air remaining inside expands. Temperature and pressure measurements of the air inside the vessel are recorded. These two measurements are used to produce the polytropic exponent n for the expansion process. Historical background Sadi Carnot (1796-1832) [1] in his 1824 â€Å"Reflections on the Motive Power of Heat and on Machines Fitted to Develop This Power,† examines a reciprocating, piston-in-cylinder engine. Carnot describes a cycle applied to the machine appearing in Figure 5.1, which contains his original sketch. In this figure air is contained in the chamber formed by the piston cd in the cylinder. Two heat reservoirs A and B, with temperature greater than temperature , are available to make contact with cylinder head ab. The reservoirs A and B maintain their respective temperatures during heat transfer to or from the cylinder head. Carnot gives the following six steps for his machine: 1.The piston is initially at cd when high-temperature reservoir A is brought into contact with the cylinder head ab. 2.There is isothermal expansion to ef 3.Reservoir A is removed and the piston continues to gh and so cools to . 4.Reservoir B makes contact causing isothermal compression from gh to cd. 5.Reservoir B is removed but continual compression from cd to ik causes the temperature to rise to . 6.Reservoir A makes contact, isothermally expanding the air to cd and thus completing the cycle. A decade later Clapeyron [2] analyzed Carnot’s cycle by introducing a pressure-volume, p-v diagram. Clapeyron’s diagram is reproduced next to Carnot’s engine in Figure 5.1. Claperon labels his axes y and x, which correspond to pressure and volume, respectively. We will examine two process paths in this diagram: the isothermal compression path F-K and the isothermal expansion path C-E. Since both of these processes are isothermal, pv = RT = constant. This is a special case of the polytropic process , where, for the isothermal process, n = 1, so we have the same result, pv = c. Figure 5.1 Left sketch: Carnot’s engine, after Carnot [1]. Right sketch: Clapeyron’s pressure-volume, p-v diagram, after Clapeyron [2]. For the axes in Clapeyron’s diagram x = v and y = p. The Experiments Photographs of the equipment appear in Figures 5.2 and 5.3, and a sketch of the components appears in Figure 5.4. steel pressure vessel discharge valves thermocouple conduit pressure transducer Figure 5.2 The polytropic expansion experiment at Cal Poly. thermocouples thermocouple conduit Figure 5.3 Two, Type-T thermocouples are located inside the pressure vessel, at the geometric center. Only one thermocouple is used – the other is a spare. In the photo the thermocouple conduit has been removed and held outside of the vessel. The junctions of these thermocouples are constructed of extremely fine wires (0.0254mm diameter) that provide a fast time response. Figure 5.4 The polytropic expansion experiment equipment. Pressure measurements come from the pressure transducer tapped in to the pressure vessel shown in Figure 5.4. The transducer is powered by the unit labeled â€Å"CD23†, which is a Validyne [3] carrier demodulator. The fine wire thermocouple is described in the Figure 5.3 caption. Both thermocouple and pressure signals feed into an Omega [4] flatbed recorder. The three discharge valves on the right side of the vessel have small, medium, and large orifices. These orifices allow the air inside the vessel expand at three different rates. The pressure vessel is first charged with the compressed air supply. This causes the air that enters the vessel to initially rise in temperature. After a few minutes the temperature reaches equilibrium at which time one of the discharge valves is opened. Temperature and pressure are recorded for each expansion process. These data are then used to compute the polytropic exponent n for each process. It is important to note that the temperature and pressure of the air inside the vessel are measured, not the air discharging from the vessel. Data Pressure and temperature data, for the three runs, are provided in the EXCEL file â€Å"Experiment 5 Data.xls.† Analysis In many cases the process path for a gas expanding or contracting follows the relationship (5.1) The polytropic exponent n can theoretically range from . However, Wark [5] reports that the relation is especially useful when . For the following simple processes the n values are: isobaric process (constant pressure)n = 0 isothermal process (constant temperature)n = 1 isentropic process (constant entropy)n = k ( k=1.4 for air) isochoric process (constant volume)n = ï‚ ¥ In our experiment the steel pressure vessel is initially charged with compressed air of mass . Next, the vessel is discharged and the remaining air mass is . This final mass was part of the initial mass and occupied part of the volume of the vessel at the initial state. Thus expanded within the vessel with a corresponding change in temperature and pressure. Therefore mass can be considered a closed system with a moving system boundary and the following form of the first law of thermodynamics applies (5.2) If the system undergoes an adiabatic expansion , and if the work at the moving system boundary is reversible. Furthermore, if we consider the air to be an ideal gas with constant specific heat. With these considerations the first law reduces to (5.3) Using the ideal gas assumption and differentiating this equation gives (5.4) Substituting Equation 5.4 into 5.3 and using the relationships and gives Separating variables and integrating this equation, , yields (5.5) which is a special case of the polytropic relationship given by Equation 5.1, with n = k. It is important to note that in the development of Equation 5.5 the expansion of inside the pressure vessel was assumed to be reversible and adiabatic, i.e. an isentropic expansion. In our experiment the adiabatic assumption is accurate during initial discharge. However, the reversible assumption is clearly not applicable because the air expands irreversibly from high pressure to low pressure. Therefore we anticipate our data to yield . Two approaches are used to determined the polytropic exponent n from the data: 1. Equation 5.1 can be written as , which is a power law equation. In EXCEL, a plot of p versus v and a power law curve fit using TRENDLINE will disclose n. 2. Equation 5.6 (subsequently developed) may be used with only two states to determine n. Here is the outline of the development of Equation 5.6. We start with , which also can be expressed as and combine this with the ideal gas law to obtain (5.6) The temperatures and pressures in Equation 5.6 are all absolute and the subscripts 1 and 2 represent the initial and final states. Required 1. Pressure and temperature data are provided for all three runs in â€Å"Experiment 5 Data.xls.† Use the ideal gas law, pv = RT, to compute v corresponding to each p. Use SI units: m3/kg for v and Pa for p. 2. Plot p versus v and find n: For each run, on a separate graph, plot p [on the ordinate (vertical) axis] versus v [on the abscissa (horizontal) axis]. Use linear scales. Determine the polytropic exponent n for each run using a TRENDLINE power curve fit. Also find the correlation coefficient for each curve. (Be aware that the TRENDLINE power curve fit will give , where y = p, x = v and a and b are constants.) Plot all three runs on a single graph and find n for the combined data. 3. Derive Equation 5.6. 4. Find n for each run using Equation 5.6, where states 1 and 2 represent the beginning and ending states, respectively. 5. In a single table show all of the n values. 6.

Childhood Obesity Term Paper Example | Topics and Well Written Essays - 1000 words

Childhood Obesity - Term Paper Example Obesity prevalence is brought by poor nutritional eating habits exposing the parents of the affected children to unavoidable consequences resulting to either social stigmatization or medical related problems (Preedy &Watson, 2012). The prevalence of obesity and related condition is said to have risen rapidly amongst the children aged between 5 and 16. Despite this rate, treatment and prevention have always remained vital steps to curtail this menace (Ferry, 2011). Stake of the community health in controlling prevalence of obesity The main objective of the community health is to explore adequate mechanism of reducing obesity in children and adolescence. A number of considerations have been put in place by the health workers to ensure that the fight against such conditions is put under control. Some of the values that need to be embraced are community involvement and empowerment. All the members of the society should be sensitized about the articulate nature of obesity amongst the chil dren. Therefore, communities should be empowered to have a response to the childhood obesity while emphasizing on the environmental risks, which exploits the health of a child. Ironically, most of the food advertisements are usually directed towards the perspective of the children. Parents and the society as a whole should participate in an active role of educating children about the prospects of positive food advertisements. ... For adequate provision of comprehensive effort to curtail the prevalence of obesity, the collaborative effort must involve partisans at all levels of the society, community, organizational, interpersonal and individual. Causes of obesity In America, nearly two out of five children are either of excessive weight or are obese. There are several reasons as to the prevalent increase of obesity even though most of them can actually be controlled through slight adjustments in lifestyle changes. However, among the dominant causes of obesity includes poor nutrition. Insufficient nutrition accustomed by many Americans has been found to contain too much calories and less nutrition responsible for the development of body structures. Moreover, inadequate exercise is also considered as a major contribution of the body towards obesity. Absence of actual balance of the amount of calories that are believed to stagnate in the body after consumption may lead to radical gain in body weight. Therefore, a recommendable exercise of approximately 20 minutes daily is considered adequate to enhance distribution of fatty acids within the body (Smith, 1999). Another contributing factor is health illiteracy. Inadequate education both at the community level and the institutional levels concerning the measures of controlling obesity has never been up to date. For instance, some mothers may not be actually aware that, they are capable of eradicating obesity. In addition, some suffer from inability of translating the nutritional components of food substances. It is, however, considered of no use to consume a definite amount of food if there is no clear

Collaborative work in IDE development Essay Example | Topics and Well Written Essays - 250 words

Collaborative work in IDE development - Essay Example As a Project Manager, adapting to changing request is a crucial factor that can be the pinnacle of the success or the failure of any given project. The programmers are able to mimic the code and ‘lingo’ of the code in a very easy manner which makes development much more feasible. Visual Studio IDE also takes the workload of coding much more feasible. Visual Studios allows around the functionality of drag and drop to be supplemented with actual coding. This is perfect for even new developers who can drag and drop and then code with objects. An IDE that is somewhat similar to it is Java Eclipse. It allows individuals to have open source coding that be beneficial. IDEs are greater because even non-programmers can see the notes instead of just CLI. Java again is open source, but C-sharp is easier to program. It does diminish the value of coding because the complexity to code itself becomes easier. However even with IDEs, the role of programmers and scope has never been reduc ed. With the recent advent of enhancements, visual IDEs can even transform GUI based projects using Agile methodology, gathering business requirements, creating workflows and wireframes. Imagine a wireframe that can converted into actual OOP. Microsoft Visual Studio IDE allows each sprint to have something testable and can be given to the client much quicker than
