Biff and Happy then leave the restaurant. While Willy is in the bathroom, he goes into another illusion. He finds himself in a hotel room with a woman. She is telling him how much she loves his sense of humor. Then knocking is heard at the door, and at first Willy refuses to answer it. As the knocking continues, Willy tells the woman to wait in the bathroom. He opens the door and finds Biff there. Biff tells Willy that he has flunked math and asks that Willy talk to his math teacher about it. Biff explains that his teacher doesn't like him because he once caught Biff imitating him in class. Biff shows Willy the imitation and they both start laughing. The woman hears them laughing and comes out of the bathroom. Willy hurries her out of the room, but not before the woman demands the stockings that Willy promised her. Willy tries to explain the situation, but Biff won't listen. He accuses Willy of giving away Linda's stockings and calls him a liar and a fake. Willy is then brought out of his illusion by the waiter at the restaurant. Willy asks if there is a seed store in the neighborhood and then leaves. Later that night Biff and Happy come home and find Willy planting seeds in the back yard. Biff

National and International Contexts Essays - Foreign Relations, Law

National and International Contexts Essays - Foreign Relations, Law National and International Contexts Childhood treated as a social construction raises concerns on the condition of children (elective notes) like early exposure to adult hood, vulnerability to exploitation be it in various forms; and the several demarcations of childhood as determined by policy. For example minimum age of admission to primary education, employment, further education. Therborn (1996) describes situations of collective action to promote change. An example cited is UNICEF. It was established in the after math of world war II as a temporary measure to provide emergency-humanitarian relief. It soon took over permanency to work for children particulars in education as a measure that will ensure elimination of child labour and exploitation. The WHO came up with several programmes to develop children's well being and health. Another observations development of a rights perspective and law for children was through a Child Rights Convention. Collective action lies at heart of policy that aims to promote and safeguard welfare of children. A rights perspective has the advantage of going beyond nation state politics to an international law with a norms and standards approach that treats political environment of children in a more meaningful manner. Knuttson (1997) argues that any development approach which is directed at influencing community change should involve children as active agents of change and "Emancipation". The impact and role of feminism through impact on family care and work affects children and their rights. The state of the World's Children 2007 Report states "Gender Equality and the well being of Children go hand in hand. When women are empowered to live full and productive lives children prosper UNICEF'S experience also shows the opposite. When women are denied equal opportunity within a society children suffer (Ann M Veneman, Executive Director United Nations children Fund, State of World in children 2007- UNICEF 2007.) The International programme on Elimination of Child Labour, (IPEC) is the International Labour Organistion (ILO) response to provide direct assistance to countries to tackle child labour and give teeth to the United Nations Convention on the Rights of the Child made effective in 1989. Today (IPEC) has 30 funders and 86 programme countries.The ILO in it's report "The end of child labour; within reach" released in 2006 says, in 2004 there were 218 million children trapped in child labour of whom 126 million were in hazardous work. However the number of child labourers globally fell by 11% over the last four years, while that of children in hazardous work decreased by 26%. IPEC the campaign instrument against child labour conducted by ILO commenced in 1992 and has made several break throughs in advocacy; tackling the worst forms of child labour; developing a learning culture and mainstreaming child labour within the Decent Work agenda. ILO is also aware of future challenges. Child labour elimination may be mainstreamed into key development and Human Rights frame works like Millennium Development Goals and poverty reduction strategies. (www.ilo.org/declaration) Child labor first emerged as a major public policy issue with the impact of the industrial revolution. Industrialized Countries offered several packages of intervention to overcome presence of child labour like advocacy campaigns; public inquiries; minimum age legislation; education provision for working children. These have been expanded, in modern times and many developing counties have emulated these initiatives. The Elimination of child labour is linked with provision of compulsory, free and accessible education. Without educational opportunities it is likely that children will enter the labour market and take on dangerous and exploitative jobs. The Dakar Forum of 185 countries resolved to provide all children of primary age free schooling of quality by year 2015 and eliminate gender disparities by year 2005. Much remains to be achieved. Although concept of Education for All has not taken off the ground at an international scale, efforts are made with community groups, parents, employers, and government officials to remove children from work voluntarily and enroll them in school. An example is efforts of an NGO(MV foundation) made in India in state of Andrah Pradesh. It enabled 150,000 to be enrolled and retained in schools and more than 4,000 bonded labourers released and of 500 villages under project 168 made free of child labour. These results were achieved through awareness raising and demand for education of children; support for teachers through special training; support parents to provide alternatives to labour of child withdrawn; provide clearing schools to prepare children for formal education. (source: Child Labour a Global concern, www.schoolisthebestplacetowork.org) Some ILO actions against child labour. One of main aims set for ILO at its foundation in 1991 was abolition of child labour . ILO standards were embodied in concept of minimum age for

PM to rescue a project in trouble Assignment Example | Topics and Well Written Essays - 1000 words

PM to rescue a project in trouble - Assignment Example To ensure that one takes the right action, the cost expenditure in a project has to be measured consistently and accurately. The certainty of cost can be attained if all project activities are completed properly. There are a number of factors that can directly have an impact of a project’s final cost compared to the original budget plan on cost. Project changes and this involves unforeseen events, scope, execution method and levels of specification. There is also schedule whereby the sooner the completion of a project, the sooner a project does not incur costs. The foreseen events is another factor which means that although the original plan on cost where contingencies and risks are concerned, events can take place as foreseen although with a different impact on the affected cost elements. The control schedule enables a person to understand the variance nature and its cause, capturing of current schedule, determining the variance from the baseline of the schedule and responding by taking relevant measures. The control schedule helps to monitor and control a group by influencing what changes to be made before a project is affected. The control schedule keeps the expectations of a managing stakeholder through advice on the type of work, how it should be carried out, which members to carry it out, and the duration of time it will take. The control schedule gives advice on when a project can be reviewed and when the authorized product to be complete. Schedule management plan defines how a control schedule can be changed and managed. It articulates the variances of schedule performance thus defining the circumstances when schedule reserve can be used. Project schedule is a major and obvious input to control schedule since it consists of a daily schedule used to monitor and keep track of project work thus giving resource against results being managed as well as

Martin Luther King and Alice Walker Essay Example | Topics and Well Written Essays - 1500 words

Martin Luther King and Alice Walker - Essay Example Martin Luther King's epiphanies however, were such that they changed the face of a nation. When the Other Dancer is the Self by Alice Walker takes a beautiful and pertinent look at what drives women and particularly little girls. Beauty is something we all strive for, especially in today's media conscious world. It is really a connection between self confidence and self esteem that Alice Walker talks about. In the beginning of her memoir she speaks about being beautiful or 'cute' and having attention poured upon her. She remembers everything she is wearing and even what the day was like until the change occurs. In some instances where a tragic event changes a person's life they forget the good times, when everything seemed to be alright and focus rather on the event that changed their lives. Alice Walker has a vivid memory of the times when her confidence was high. There are essentially two paragraphs that describe these times and then one line that explains the change. That one line has its purpose in that effectively closes a chapter. Walker writes: "It was great fun be ing cute. But then, one day, it ended."(Walker 55). Alice Walker remembers then the tiniest detail of what changed her life and that scar that seemed to rip a gaping hole through her existence. There are actually two turning points within this story that both deal with the 'self' and the coming of age into a world where ones physical appearance no longer matters as much. When Alice Walker was shot, she had been known as a certain person and she feels thereafter that she was no longer that person. She remembers being changed and asking those around her whether or not she had changed. "Years later, in the throes of a mid-life crisis, I ask my mother and sister whether I changed after the 'accident.' 'No,' they say, puzzled. 'What do you mean'" (Walker 56). In this journey Walker begins to ask herself whether the change was part of her imagination. She wonders if that change was something so small yet significant that others could not see it. There are two ways of looking at this chang e or turning point. The first transition is when she was shot and when she imagined this change as being all-encompassing. The second change is when she realizes that it really made no difference and the way she sees herself is not necessarily the way the world sees you. Take for instance an acne sufferer: their condition has cleared up but they are so fixated on the one blemish that does not clear up that they believe this all other people see. They are often shocked when those around them honestly never noticed it. Alice Walker's perception of herself changed when her child likened her blind-eye to the way the world looks from a distance. This is a remarkable definition of the 'self', and once a new way of defining the 'self' is recognized, it puts everything else into perspective. Women are eternally concerned about their appearance perhaps still due to the old way of thinking in biological terms. Hundreds of years ago, a woman's future relied on finding a man and being able to k eep him. He was her security, which meant that keeping him from straying was important and therefore preservation of appearance was also imperative. This mind-set has not yet been abolished. The way others view our appearance is very much dependent on how we view ourselves and what we are aware of within that self. Alice Walker was more confident after the

System Evaluation Paper Essay Example for Free

System Evaluation Paper Essay No doubt, EDI or electronic data interchange process has increased efficiency in exchanging business documents between companies. This process replaces faxing and mailing of documents. The process utilizing specific record formats that are based on widely accepted standards (CovalentWorks, 2014). EDI is used in a variety of industries; over 160,000 companies have switched to EDI to increase their efficiencies. In addition, a vast majority of the companies require their partners to use EDI as well. Assuredly, there are many benefits and some drawbacks for companies that use EDI. One major benefit of EDI is the computer-to-computer exchange of information is much less expensive than handling paper documents. Moreover, studies have concluded that the processing of a paper-based order can cost of up $70 or more. On the other hand, the processing of an EDI order will cost less than a dollar. Other benefits of EDI are much less labor time required fewer errors because the documents are processed by computers, and a faster flow of business transactions (CovalentWorks, 2014). In addition, fast transactions assist in reducing inventory levels, increase warehouse space, decrease out-of-stock levels, as well as lower freight costs. However, one drawback is companies must ensure they have the resources in order to make EDI successful. The resources are attained by purchasing, hiring, and outsourcing. Nevertheless, some of the costs may be offset by the increased efficiency of EDI. EDI works when a buyer prepares an order in the purchasing system and has is approved. Next, the EDI order is translated into an EDI document format called an 850 purchase order (CovalentWorks, 2014). The purchase order is then transmitted to the supplier either by the internet or through a VAN (Value added network). If the VAN is the chosen delivery route between the buyer and supplier, it is always sent on a secure and reliable network. In addition the supplier’s  VAN ensures the supplier receives the order. The supplier’s computer system processes the order. Hardw are, software, internet access, and e-mail are required for the processing to take place. Passwords, user identification, and encryption are used to maintain data security and control throughout the transmission. Lastly, the buyer’s and suppliers edit and check the EDI documents for accuracy (CovalentWorks, 2014). EDI (electronic data interchange) is utilized at my current employer which is a large retail drug store chain. Our chain uses EDI for supplier’s orders, as well as processing invoices and credit memos. For example, a soda vendor will visit our store, merchandise the shelves, and then write an order. The order connects through EDI into our system. Additionally, the order can be viewed as a pending order on the AS400 computer. On arrival, one barcode (per pallet) is scanned in with a Telxon unit. The invoice number and quantities of the order automatically populate and the on-hand quantities are adjusted once the invoice is posted. However, not all vendors are set up through EDI. Through EDI, once the invoice has been posted, it is just filed in the office because the supplier will be automatically paid. If the supplier is not set up through EDI, then the invoice must be stamped with a receiving number and mailed to the corporate office for payment which is a much longer process. Non-EDI invoices risk the chance of getting lost and require a lot more postage and labor revenue to process. However, more and more of our vendors are transitioning to EDI, especially the ones that supply us with product consistently every week. The business requirement that drove the system’s initial development is the labor intensive high cost supply chain. Moreover, there was a need for improved efficiency with ordering, updating on-hand quantities, and payment of invoices and the receipt of credit memos. The company has over 8,000 stores. Therefore, if each store averages 5 invoices per day, that is 40,000 invoices per day that need to be processed. EDI potentially can save thousands of dollars daily in the reduction of labor hours. Furthermore, it reduces the chance of errors and non-payment of received merchandise. In conclusion, EDI has many more benefits than drawbacks. EDI transmits and processes documents very cost effectively, efficiently, and accurately. I believe the company I work for will continue to make EDI arrangements with non-EDI vendors. I also think larger companies and corporations will follow suit and transition to EDI if  they have not done so already. References Covalentworks (2014). Electronic Data Interchange.

Example Of Primary Key Computer Science Essay

Example Of Primary Key Computer Science Essay Database is a structure that is generally divided in two respects, namely a flat database and a relational database. Relational database easier to understand than the flat database. Because relational database has a simple design and it is easy to do data operations. Database also has a relational structure found in tables to store data. On each table is it consists of columns and rows and a column to define the type of information that should be saved. Basically the database is very useful when the time to retain the information that will be categorized logically. For example, if you want to save the information on the data, the database enterprise or school, it can be in a group with matters in business become more tables. In the database there is some relationship, the relationship is as one to one, many to many, one to many, Primary Key The key is a set of columns that can be used to identify or access a particular row or rows. Identified key explanatory tables, indexes, constraints or reference. The same column can be part of more than one key. A unique key is a key that is constrained so that no two values à ¢Ã¢â€š ¬Ã¢â‚¬ ¹Ãƒ ¢Ã¢â€š ¬Ã¢â‚¬ ¹are the same. Unique key columns cannot contain NULL valuesà ¢Ã¢â€š ¬Ã¢â‚¬ ¹Ãƒ ¢Ã¢â€š ¬Ã¢â‚¬ ¹. For example, the column number of employees can be defined as a unique key, because each value in column identifies only one employee. No two employees can have the same number of workers. The mechanism used to enforce uniqueness of the so-called index unique key. Unique index table is a column, or a collection of ordered columns, each of which identifies value (specify function) unique rows. A unique index can contain NULL valuesà ¢Ã¢â€š ¬Ã¢â‚¬ ¹Ãƒ ¢Ã¢â€š ¬Ã¢â‚¬ ¹. The key is one unique key defined on the table, but was selected as the first important key. There can be only one primary key on the table. A primary index is automatically created for the primary key. The main index used by the database manager for efficient access to table rows, and allows the database manager to enforce the uniqueness of the primary key. (You can also specify non-primary index key columns efficiently access the data when processing the query.) If the table does not have a natural unique key, or if the order of arrival is a method used to distinguish unique rows, use a time stamp as part of the key can help.

A key with more than one column is a composite key. The combination of column values à ¢Ã¢â€š ¬Ã¢â‚¬ ¹Ãƒ ¢Ã¢â€š ¬Ã¢â‚¬ ¹should define a unique entity. If a composite key cannot be easily defined, it can also be considered to create a new column with unique valuesà ¢Ã¢â€š ¬Ã¢â‚¬ ¹Ãƒ ¢Ã¢â€š ¬Ã¢â‚¬ ¹.

Foreign keys can be used to cross-reference table. For example, suppose we have two tables, customer that includes all customer data, and the order table that includes all customer orders. Intention here is that all orders must be associated with a client who is in the customer table. To do this, we will place a foreign key in the order table and it relates to the key customer table. Identifying foreign key column or set of columns in a table that refers to a column or set of columns in another table. Column in the table must reference the key pillars or other super key in the referenced table. Value in a reference column line must occur in a single row in the referenced table. Thus, a row in the reference table cannot contain values à ¢Ã¢â€š ¬Ã¢â‚¬ ¹Ãƒ ¢Ã¢â€š ¬Ã¢â‚¬ ¹that do not exist in the referenced table (except potentially null). In this way a reference can be made to link information together and it is an important part database normalization. Various rows in the table reference may refer to the same row in the referenced table. Most of the time, it reflects a (parent table or reference table) to many (child table, or referencing table) relationship. Example Foreign Key Below is an example of the relationship between the Company and also schedules, Contact. Tables in the company is the parent of a link. In child contact schedule, Field CompanyID the table to show the contact contacted the company owned. The role of the Son (Multiplicity) Diversification foreign key defines how many records in the child table can link to records in the master table. In the above example the childs diversity since a company can have any number of contacts. Example Primary Key Foreign Key Relationship It have a Primary Foreign Key, in this figure it have a relationship between this two keys. e.g. One to One , One to Many , Many to Many. Primary key. This is indicated by the Primary Key field equivalent to the schedule. this shows that the field that identifies a unique record. For example, Product_ID product and ORDER_ID for Order the values à ¢Ã¢â€š ¬Ã¢â‚¬ ¹Ãƒ ¢Ã¢â€š ¬Ã¢â‚¬ ¹that are normally produced by the field is Auto-rise. they do not have any intrinsic meaning and only integers are automatically generated one by one. Primary Key and Foreign Keys. This indicated that the PF with the field in the table. In this case, the field is also created as a key example of this attitude in the Schedule of Key, Primary Key in Table Customer_Orders_Products is a composite key, consisting of two fields. The product_id is the Primary Key in the table Products, and ORDER_ID is the Primary Key in the table Customer_Orders. One-to-Many Relationship. One-to-Many very common in the real world, and it is very easy to read that A Parents can have a lot of children. In this figure shows that, One Product can be attributed to Customer_Orders_Products the Many. The line between product and Customer_Orders_Products is continuous line (not small dotted lines). This means that the product_id field is the Primary Key in Table Customer_Orders_Products. A dotted line will show the existence of a Foreign Key. Many-to-Many Relationships. Relationship Many-to-Many very important in the real world, and being able to see them all around us every day. For example, many customers may order the same product. Many products can be ordered by the same customer. This is called Relationship Many-to-Many. It can not be implemented directly in the Database Table relationships. The solution is to create an intermediate table that records all the combinations that exist between the Customer and Product. For example, if a customer who ordered three products, then there will be three records for that customer in an intermediate table. Low key combination to be a parent table primary key intermediate in this table. We also need to allow for comments like Make it stronger,. If we get to the right database structure, then it is very easy to extend it. Question 2 Explain the main characteristics and advantages of the following terms. a ) Relational Database b) Object Oriented Database c) Object Relational Database Relational Database Can be connected to a database with a collection of data items is strongly recommended as a set and the name of the Minister of Finance official explained from Any data easily accessible. A database was created using the model relations relationship. The software used in database relations database management system called Relations. A relationship database is the preferred choice in storing data, as compared to other models such as the hierarchical database model or network model. The first database is been commenced in 1970, namely by Edgar Codd. Advantages of Relational Database Avoid Error There is only a single storage location for any piece of information, so: data update is easy without having to change the same information in 15 different files. info is always up to date there is no chance of remaining old data in some forgotten file. Number and date: no typos such as 10, 10, 10, not 10. avoid problems such as data type in Excel dreaded syndrome. avoid unwanted text-to-date conversion like November 12 to be November 12 1900. Error checking data as they are entered: validated data on data entry, to filter the impossible data can be cross-checked against existing information. Manipulate Data With databases it can combine different data easily. No more error-prone cut-and-paste to force data into different formats. Do away with all intermediate Excel spreadsheet that is often generated when manipulating data. (And which you often darent delete just in case they contain important information.) Data manipulation is done by using a query. This means Structured Query Language, SQL, to merge, update and manage data, but most users do not need to know any SQL to perform complex tasks. In Microsoft Access, for example, Visual Query Builder provides a simple, intuitive interface makes most queries. Visualize Data A database is being adjusted can reveal new areas for investigation to present large quantities of data in an intuitive form. Often the patterns become apparent only by flicking through data. With this special database it is possible in new ways: data from many different sources can be brought together and displayed quickly and and fast. Integrate with analysis Ends with an Excel file to a multi-analysis, each subtlety different? Never sure that the correct file is not delete any, just in case. With a relational database, this is the dilemma of the past. Your data set for analysis is created using queries stored in the database. No copy is made of data, but instead you link to query directly from the statistics. Object Oriented Database Reduced Maintenance The main goal of the object-oriented development is a guarantee that the system will enjoy a longer life while having maintenance costs much less. This is because most of the processes in the system contained, behavior that can be reused and will be included in the most recent behavior. The ultimate goal is for the new object-oriented development Real World Modeling Objects operational system is very prone to model the real world in a more complete fashion than do traditional methods. Objects that have been organized into a class of objects, object-related behaviors. Based on the object, rather than on data and processing only Improved Reliability and Flexibility Object-oriented system to be far more reliable than traditional systems, especially in the new behavior can be built from existing objects. Because objects can be dynamically called and accessible, new objects can be created at any time. New objects can inherit data attributes from one, or many other objects. Behavior that can be inherited from the super-class, and novel behavior can be added without performing the functions of the existing system. Object Relational Database Database Object capabilities can be expanded with additional ties and new data types, access methods and functions available in object oriented programming. it can add character string with alpha-numeric data types. Complex data types can combine features of data types that already exist in the database. here it is able to determine the data type of text containing desired time or with the number of bytes used to create user defined data types can be opaque or own. it can also add user-defined virtual processors. Encapsulation By using encapsulation of database object you want to contact in the form of a table. For example, Table 1 includes the name, address, phone number and email address for contact. Through class encapsulating Contacts, it just combines all this information in a table on this one. So when you query the database for this information, you generate a report in a style designed to include all of this information.

Global Poverty Essay

The definition of poverty is a matter of debate. In 1795, English magistrates decided that a minimum income should be the cost of a gallon loaf of bread, multiplied by three, plus an allowance for each dependent. Today, the Census Bureau defines the threshold of global poverty as the minimum amount of money families need to purchase a nutritionally adequate diet, assuming they use one-third of their income for food. The term underclass has been applied by some social scientists to a population of people, concentrated in an inner city, who are persistently poor, unemployed, and dependent on welfare, with an emphasis on persistently. Initially, sociologist William Julius Wilson championed the concept to describe the plight of the truly disadvantaged. But he and a number of other sociologists have since expressed concern that the term underclass is being misused by some journalists and political conservatives to argue that the poor have created their own plight and are to blame for their poverty (Hinkle, 1994). Wilson contends that the underclass exists mainly because of a sharp climb in inner-city joblessness by virtue of the elimination of hundreds of thousands of lower-skill jobs, the growing polarization of the labor market into low-wage and high-wage sectors, the relocation of manufacturing industries out of the central city, and periodic recessions. The problem has been compounded by the concentration of the disadvantaged in inner-city ghettos and the isolation of these areas from more affluent communities (Hinkle, 1994). Before World War I, most African Americans lived in the rural South. But industrial jobs during World Wars I and II drew hundreds of thousands of blacks to cities in the North (Davis, 2004). Almost all of these people were poor, unskilled workers. Structural factors, i. e. the disappearance over the past quarter-century of hundreds of thousands of low-skill jobs, mainly involving physical labor, have meant that inner-city blacks have become a severely disadvantaged class (Hinkle, 1994). They settled in slum areas near the factories where they worked in the inner city. As slums grew, ghetto conditions worsened. These patterns are most evident in large American cities where smokestack industries once attracted young men with few or no skills to jobs that nonetheless paid well enough to support wives and children. Prejudice and discrimination have made it difficult for African Americans and other minorities to improve these conditions. Legislation has been used to try to eliminate ghetto conditions in the United States. But segregation remains a serious problem. Now poor urban blacks find themselves relegated to all-black neighborhoods where they are socially isolated from mainstream life (Davis, 2004). According to the conflict theory, though, the underclass indeed constitutes a minority of the poor. The underclass is a cote of inner-city poor, those individuals and families who are trapped in an unending cycle of joblessness and dependence on welfare or criminal earnings. Their communities are plagued by drug abuse, lawlessness, crime, violence, and poor schools. Many underclass women were teenage mothers and high school dropouts who subsequently found themselves sidetracked without the resources or skills to escape a life of poverty (Hinkle, 1994). Some sociologists portray global poverty as a structural feature of capitalist societies. The cyclical movements between economic expansion and contraction, boom and bust, contribute to sharp fluctuations in employment (Iceland, 2003). A century ago, Karl Marx contended that an industrial reserve army is essential for capitalist economies. The industrial reserve army consists of individuals at the bottom of the class structure who are laid off in the interests of corporate profits during times of economic stagnation, then rehired when needed for producing profits during times of economic prosperity. It is disproportionately composed of minorities, who traditionally have been the last hired and the first hired. Contemporary structural functionalists say that a new industrial order characterized by a significant shift from manufacturing to service-sector employment has produced massive vulnerability among all blue-collar workers (Hinkle, 1994). Poverty derives from a lack of income-producing employment. And high inner-city rates of family disintegration, welfare dependency, drug abuse, and crime are additional outcomes of faulty economic organization. Clustered in large ghettos and squatters Mexico, Africa, and some parts of Asia, the poor develop feelings of marginality, helplessness, dependence, and inferiority. These circumstances allegedly breed weak ego structures, lack of impulse control, a present-time orientation characterized by little ability to deter gratification, and a sense of resignation and fatalism. The resulting lifeways are both an adaptation and a reaction of the poor to their disadvantaged positions (Iceland, 2003). They become self-perpetuating patterns as the ethos associated with the culture of poverty is transmitted to successive generations. United Nations bureaus revealed that nearly half of the state’s children have mothers who have failed to fulfill elementary school. Statistics illustrate there exists a positive relationship between parents’ educational attainment and their offspring’s odds in their latter life. Children of parents who have no adequate formal education are prone to endure scarcity as they age. Poverty-stricken people around the world suffer from the lack of many things they need. For example, they are less likely to receive adequate medical care or to eat the foods they need to stay healthy. The poor have more diseases, become more seriously ill, and die at a younger age than other people do. Poor people often live in substandard housing in socially isolated areas where most of their neighbors are poor. Many low-income families live in crowded, run-down buildings with inadequate heat and plumbing. The jobs most readily available to the poor provide low wages and little opportunity for advancement. Many of these jobs also involve dangerous or unhealthful working conditions. Financial, medical, and emotional problems often strain family ties among the poverty-stricken (Iceland, 2003). In Laos, saddled with debt, lacking infrastructure, and short of trained personnel, the government simply cannot afford to provide basic schooling for all of their children. However, this is not a problem of lack of resources, but rather a problem of resource allocation. In Ghana, misdistribution and capitalistic exploitation make the medicines inaccessible to the poor clients in the district. If in the past, the causes of illnesses may have been shared between man and nature, from this time forth, diseases are brought about by the caustic arms of industrialization, which might have not destroyed or alternatively benefited the sub-Saharan Africa. In Thailand, young people, some hardly elapsed pre-school age, vending on streets virtually every single day is a heartbreaking scene to the passersby. While at first glance it may seem to be effortless, risk-free toil that equips a deprived family a most wanted boost, it essentially stems from a chain of causes, and begets a mesh of costs for the child, his family and the society in which they are trying to survive. Eventually, many unschooled children would eventually realize finding themselves sidetracked without the resources or skills to escape a life of poverty. Within the United States, President Lyndon Johnson’s Great Society produced a flurry of social programs rivaling those of Franklin Roosevelt’s New Deal. Some are gone, while others were severely cut or revamped by the Reagan and Bush administrations. The government provides two main types of aid: social insurance and public assistance. Social insurance mainly covers people-or their families-who have worked and paid special taxes in the past, whether or not they are poor. Public assistance provides aid to the needy regardless of their work record (Iceland, 2003). Education is a key element in reversing poverty. For some people in Asia and Africa, education is a means to improve oneself. Education is greatly related to social status because a high degree of education involves money and motivation. Some people insist that the forces that are making the world into a single economy have separated people from longstanding identities and have, at the same time, weakened nation-state. Particularly, McDonaldization of global society has allowed to target highly specific groups wherever they are and so the ethnic bond tails them too (Ritzer, 1996). People in developing countries are starving, purely so that our developed society can be provided with excess food. Chemicals, necessary for the uniformity of its products, are destroying the environment and putting lives at risk due to increased nitrate levels. This way, McDonaldization of society wouldn’t make the world a better place, as it will simply turn into a bigger breeding ground for exploitation, pollution, and economic imbalance around the world furthering global poverty.

Parameters for a Computational Fluid Dynamics Analysis

ANSYS Fluent is technology package for computational fluid kineticss which enables mathematical modeling of the physical theoretical account. It can be used to analyze fluid flow, heat transportation and a broad scope of other industrial application jobs by executing â€Å"numerical experiments† ( computing machine simulations ) in a â€Å"virtual flow laboratory† . The package is extensively used throughout the universe. It can be used for new construct mold, every bit good as the betterment of bing 1s. One advantage of the package is that it is able to work out complex 3-D jobs where the physical forces and flow features are sometimes impossible to mensurate ; accordingly provide speedy, efficient, more accurate and dependable consequences. As mentioned before, this methodological analysis is based on using the physical theoretical account to a scaly geometry that represents the existent theoretical account system. Subsequently, all surfaces and volumes of the sphere are meshed. The full mesh is exported to ANSYS Fluent for the numerical solution of Navier-Stokes equation. Followed by the model been delegating to the boundary conditions necessary for the stuff and thermic belongingss. The theoretical account re-produces the existent atmospheric conditions that the system is subjected to during the clip that is simulated. Project’s efficiency is improved for undertakings by analyzing little alterations in parametric quantities and CFD expends less clip than building a existent paradigm and proving. One of the chief purposes of CFD simulation is to analyse the existent thermic behaviours of the proposed system with fewer resources in less clip. In this undertaking, the CFD package bundle of ANSYS FLUENT version 15.0 is selected as the computational package for imitating the physical theoretical account. This is because it is the package widely used by research workers internationally in the country of thermic wall research and besides suggested by the supervisor ( ANSYS UK Ltd, 2012 ) . The computational theoretical account is developed based on a proposed physical life infinite theoretical account in Sydney with a H2O wall system.3.2.1 Heat Balance and Governing EquationsHeat balance:The H2O wall theoretical account set up is based on the heat balance method where the temperature fluctuation for H2O is tantamount for both paradigm and theoretical account. There are a few premises made for this method:The H2O is well-mixed ab initio at a unvarying surface temperatureHeat flux moving on the surface is changelessDiffuse radiating surfaceThe thermic energy radiated on wall surface is transferred to H2O, with no heat loss to en vironing walls.Regulating equations:The heat transportation and air flow in this theoretical account is chiefly governed by partial non-linear differential equations, which stand foring the preservation of mass ( continuity ) , impulse and energy ( heat ) . These equations are so solved numerically based on the project’s geometry, boundary scenes and runing conditions. In this undertaking, the preservation equations for laminar flow are described below with concise account on each.Conservation of mass ( besides known as continuity equation ) : this equation ensures that the mass is conserved when fluid is in gesture. Equation ( 1 ) below is a general signifier of the continuity equation.( 1 )Conservation of impulse: the equation is shown below as Equation ( 2 ) .This equation rises from using Newton’s 2nd jurisprudence to the fluid gesture, where the rate of alteration of impulse peers the amount of the forces. The entire impulse of a system remains changeless.( 2 )Con servation of energy: this equation refers to the first jurisprudence of thermodynamics, where the rate of alteration of energy of a fluid partial is equal to the rate of heat add-on plus the rate of work done. In other words, for this undertaking the energy equation histories for the heat act on the undertaking. There are many ways of showing the energy equation, one signifier is as shown in Equation ( 3 )( 3 )3.2.2 Geometry and Boundary ConditionsGeometry:The conventional diagram of the analysis theoretical account considered in this paper is illustrated in Figure3-2, modeled with ANSYS Fluent. The theoretical account is developed from an false physical paradigm by ignoring the structural characteristics. In order to simplify the job, the geometry of this system is specified as planar and constructed on the X, Y plane. The theoretical account geometry is scaled down to 200mm*200mm in general infinite with a thermic storage wall and two gaps as air recess and mercantile establishmen t ( shown in ruddy ) . All wall thicknesses are neglected in this state of affairs, which indicates the walls have zero heat conductivity opposition. There are three chief parts in this theoretical account: the air channel ( A ) , inactive solar wall ( B ) and indoor life infinite ( C ) , besides illustrated in Figure 3-2. The thermic wall is set as 30mm*100mm. The intermediate infinite between the thermic wall and the glazing or the canal breadth is set for 20mm and the stuff to construction the thermic storage wall is H2O.Boundary Conditionss:The lone un-insulated surface is the interface between the thermic wall and the air channel. The other beds are insulated to either increase the thermic opposition or prevent to heat from reassigning into the internal infinite. Note that the heat flux is originally designed to move on the exterior H2O wall surface ( the surface between A and B on Figure 3-2 ) , where this surface is besides an interface between H2O and air. But mistakes occur if this interface is subjected to external heat beginning when operating in ANSYS FLUENT 15.0 bundle. Thus that in this survey, all interior wall surfaces including the roof and floor are set to be adiabatic ( under nothing heat flux ) while the thermic wall interior surface ( No. 19 on Figure 3-2 ) is capable to heat flux calculated based on the Sydney part historical informations shown in Appendix A ( Bom.gov.au, 2014 ) . However, the value of solar heat flux is non changeless during a twenty-four hours, and at this phase our cognition is non sufficient to execute a simulating based on the world parabolic behaviour of heat flux. The heat flux moving on the H2O wall for this undertaking is assumed as changeless. It is about impossible to make an accurate grading based on all fluid flow factors, to fulfill this, the H2O temperature will lift above 100EsC. To simplify the undertaking, the values are so scaled down to fulfill the theoretical account scenes by keep the same addition temperature addition rate in H2O wall. The grading computation is described below. Initially the standard temperature for the H2O wall and theoretical account room was set the same as 300K ( 26.85EsC ) . The air temperature at recess and mercantile establishment were besides assumed changeless and tantamount to the room air temperature to simplify the undertaking. By making this, heat flux is ensured as the lone force that initiates the full system. Other than the computational recess and mercantile establishment, the remainder of the surface boundaries are stationary walls under no-slip conditions. Resistance to flux due to friction along the surfaces is assumed negligible.3.2.3 Imitating Parameters ( Dimensional Analysis )From the published literature, many different parametric quantities can impact the public presentation of the H2O wall public presentation for air airing intent. As shown on Figure 3-3, there are many variables that can be investigated to optimise the H2O wall system public presentation such as wall tallness ( H ) , width ( B ) , intermediate infinite interval ( D ) and the heat flux strength moving on H2O wall surface. A dimensional analysis is performed to show the structural and mechanical parametric quantities that may impact the system public presentation. Buckingham theorem is the method used for dimensional analysis. First of wholly, a certain figure, â€Å"n† , of relevant dimensional physical variables are determined for this undertaking. These variables are inter-related and can be expressed via a functional relationship as shown in Equation 4, where Q stands for the mean volume flow rate at the mercantile establishment. ( 4 ) Followed by examine these parametric quantities and happen out the figure of cardinal dimensions, named â€Å"k† . Finally, by choosing â€Å"k† figure of reiterating variables, the staying ( n-k ) variables can organize ( n-k ) sets ofgroups. The elaborate working out is described in Appendix B. The solution indicates that for this undertaking analysis, there are n=16 variables, k=4 cardinal dimensions which form 12groups. Thesegroups are dimensionless groups that will impact the system public presentation. Consequently, The Buckingham Theorem consequence indicates that Q is a map of a set of dimensionless groups, which are shown below. ( 5 ) Due to constraint in clip and CFD cognition restriction at the current phase, in this survey, two factorsheat fluxstrengthandH2O wall thicknesshave been chosen as the simulating parametric quantities, therefore that the undertaking aims to analyze their effects on the system. Solar heat flux strength is one of the most widely research parametric quantity and besides the most conclusive. Research workers find that air velocity and temperature within the solar channel of the thermal wall system increases with increasing solar heat flux strength ( Budea, 2014 ) The 2nd parametric quantity is the H2O wall thickness ( breadth ) . Presently, research workers return assorted reappraisals on the influence of H2O wall’s tallness, but besides to observe that the tallness parametric quantity is non easy to command due to realistic structural limitations. Meanwhile, there has been really limited reappraisal on the effects H2O wall thickness parametric quantity by past research workers. Comparing to the H2O wall tallness, the thickness is considered as a comparatively easy parametric quantity to command. The above grounds explain why H2O wall thickness is selected as the 2nd simulating parametric quantity to analyze for this undertaking.3.2.4: Operating ConditionSolution Methods:As the air flow is driven by convection in the air chamber, the system is running under force per unit area based attack. When simulating, the force per unit area field is extracted by work outing a force per unit area rectification equation which is obtained by pull s tringsing the preservation of mass and impulse equations of the speed field ( Arc.vt.edu, 2014 ) . Since the government equations are non-linear, the solution procedure involves work outing the regulating equations repeatedly till the solution converges. In this theoretical account, the perkiness consequence of air is modeled under the Boussinesq estimate. This is because the phenomenon in the solar channel is natural convection under alterations in air temperature. This estimate is used to account for the denseness fluctuation. Thus the computational theoretical account considers denseness to be changeless except for the perkiness term in the impulse equation.Operating Parameters:As discussed before, the two parametric quantities interested are heat flux strength and H2O wall thickness. For the heat flux strength, the scaly upper limit summer heat flux is 112; where the minimal winter 55.7. Two other heat flux strengths are chosen for comparing. The values are taken mediate the upper limit and lower limit based on tantamount increase. Therefore, the concluding four values selected for this undertaking are 55.7, 74.593.2and 112. When analyzing the H2O wall thickness affects, the heat flux is set independent with a value of 89.2, which is the mean annual value calculated. Then the breadths selected for the H2O wall are 25mm, 30mm and 35 millimeter to compare public presentation of natural air airing of the undertaking theoretical account.3.2.5 Convergence Criteria and MeshingConvergence StandardsThis theoretical account uses 2neodymiumorder truth ( high declaration ) for the sing variables such as temperature and speed. All remainders are scaled and the convergence standard is said as reached when the default absolute value of the remainders are belowHowever it is of import to observe that a good initial conjecture by and large lead to a high scaled residuary and therefore the convergence standards can non be achieved. Hence after corroborating the solution conditions, a mesh independence trial is required to be performed to guarantee the solution is besides independent of the mesh. This is besides an extra c ritical standard to guarantee the consequences are dependable.Finite volume methodThe solution method employed in ANSYS FLUENT is known as the finite volume method under full-coupled convergent thinker. Full-coupled means that the system usually converges in less loop, but with each loop takes longer. This method operates as follows: First of wholly, the theoretical account sphere is discretized, through the usage of mesh, into a finite set of control volumes. Next, the three regulating equations discussed before ( preservation of mass, impulse and energy ) are integrated over each single control volume to make algebraic equations for the terra incognitas. Followed by all the equations developed all being solved to give updated consequences of the dependent variables. Consequently, an approximative value of each dependant variable at any points on the sphere can be obtained.Mesh Independency TestA all right mesh reduces the elaboration of mistakes during the extension of the solution. However, by bettering the truth of the simulation consequences through refinement mesh, the clip devouring for computational analysis is increased correspondingly. As a consequence, a mesh independence trial was performed to guarantee the appropriate mesh is used for this system. More specifically, this means that the mesh chosen is capable of bring forthing a comparatively accurate consequence but less clip devouring. Without executing the mesh independency trial, the solutions will hold a high opportunity of changing with the polish of mesh and this clearly is non acceptable for the undertaking. The polish procedure is repeated with incrementally reduced alternations in consequence until a solution that is independent of mesh is generated. The overall theoretical account sphere is foremost divided into 100*100 computational cells, and so traveling to 200*200, 400*400 cells for the mesh independence trial. The spheres near to interfaces were set with smaller grid spacing ( or finer mesh ) , the interior infinite set with larger grid spacing ( or courser mesh ) to better the truth. Two parametric quantities set as proctors are area-weighted mean temperature of the H2O wall and the mean volume flow rate at the mercantile establishment. There is no specific standard for the per centum difference between two back-to-back sets, but it is required to be moderately bantam to guarantee that no important effects take topographic point on the system when mesh alterations. The differences between the sets of consequences are analyzed in per centum by sing 400*400 engagement as mention. The consequences are besides expressed in x-y chart for better ocular comparing. The elaborate informations for mesh trial including the ocular comparing figures is shown in Appendix C. A comparing of consequences is shown in Table 3-2 below. By analyzing the consequences, it is observed that the differences between the 200*200 and 400*400 mesh are zero and less than 0.01 % for temperature and volume flow rate proctors severally. Therefore, it is believed that the 200*200 grid system has sensible imitating clip ingestion and can obtain good truth consequences for the undertaking. The mesh form is presented in Figure3-4. The observation gives the assurance that the fake solution is considered as independent of its grid.

Why Doctors Need Emotional Intelligence More Than IQ

Why Doctors Need Emotional Intelligence More Than IQ However competent and caring a physician is, there are still some areas where they might struggle- within a business-centric clinic model, for example, or when resisting a strong pharmaceutical sales pitch. Fortunately one area where most doctors excel is emotional intelligence (EI), a key quality business consultants are constantly trying to instill in shark-toothed CEOs. According to Dr. James C. Salwitz, over at KevinMD.com, â€Å"EI is the ability to identify and manage both your own emotions and those of others; to be aware of and control feelings and, most importantly, help others use emotions, in order to make calm, clear decisions.† It’s the skill set that helps doctors master their own feelings and aid  patients and families working through difficult moments. It should be no surprise that many doctors already have this talent–it’s what leads them into the job in the first place.Not every doctor can be a superstar, of course. Whether through burn out, a personal lack of empathy, or a convergence of difficult personal and professional circumstances, some doctors have trouble getting or maintaining that control over their emotions.It may help to make a mental checklist when going into a fraught situation. How quickly can you identify what you’re feeling? What the patient is feeling? What their family members are feeling? Are you thinking like a team player, and helping prepare your colleagues for pitfalls you can see coming? Can you anticipate the emotional needs of your patients and help them develop a plan to cope?Make sure you’re putting all your empathy skills to good use, and you’ll be a sought-after doctor with an enviable EI!

Le Chene et Le Roseau essays

Le Chene et Le Roseau essays Analysis of Le Chà ªne Et Le Roseau Le Chà ªne Et Le Roseau, a poem by Jean de La Fontaine, shows the contrast of the characters while moralizing about hidden strengths that are often overlooked or belittled. In this poem, the oak is personified as having a stubborn sense of strength, while the humble reed is represented as possessing the qualities of endurance, flexibility, and hidden strength. Fontaine teaches the reader his lesson through the use of nature by having the oak and the reed converse about their strengths. In the end the reed proves his point when the north wind uproots the oak, leaving it to die. The theme of Le Chà ªne Et Le Roseau is a universal one, easily recognized and understood by all. The poems central idea is that strength is not necessarily size and power, but in adaptability, endurance, and flexibility. Fontaine illustrates the theme well in these lines: Larbre tient bon; le roseau plie. Le vent redouble ses efforts, et fait si bien quil dracine celui... The poet further develops the theme with a moral which implies that humility is more important than pride. Fontaine places most emphasis on idea to help develop this moral. In the end, the pompous oaks strength is his weakness, while the humble reeds suppleness is his fortitude. Jean de La Fontaine develops well the poems mood, one of pity, compassion, and respect, through sensory images and descriptions of the characters. These lines: Un roitelet pour vous est un pesant fardeau; and Le moindre vent qui daventure fait rider la face de leau, vous oblige baisser la tà ªte; , as well as La nature vous me semble bien injuste. illustrate the sentimental atmosphere of pity that the reader feels for the reeds struggle against relatively small difficulties. Although Fontaine succeeds in creating t...

Policies to Address the problem of U.S. oil dependency Research Paper

Policies to Address the problem of U.S. oil dependency - Research Paper Example This research will begin with the statement that more than 150 years after the beginning of U.S. petroleum industry (since 1859), oil still is considered as the most strategic commodity. Given the limited capacity of oil reserves in the world and ever-increasing global demand for it, in recent decades oil has played a significant role in foreign policies of nations, especially those of great powers. Not surprisingly, oil has been an important factor in shaping bloody and costly conflicts, particularly since the World War II.   During the last decades of the 19th century and the beginning of the 20th century, America was able to meet the country’s basic needs in the energy sector primarily by using its own oil reserves. However, by the end of the 1940s, â€Å"the United States began to rely on foreign oil to satisfy rising energy demand, and the proportion of imports has been rising more or less steadily ever since†. Today, according to U.S. Energy Information Administ ration (EIA), the United States is the largest oil consumer and consumes near 22% of the total production of oil in the world. That is equivalent to something about 18,771,000 barrels per day, of which about 9.7 million barrels (51%) are imported (on a net basis) from foreign countries. However, this dependency on oil is very costly and also is tightly linked to our national security due to both potential economic and political threats related to it.  

Weight trining Essay Example | Topics and Well Written Essays - 250 words

Weight trining - Essay Example The article recommends routine training and after every 12 weeks, one takes a week off of weight training to cure any minor injuries and to give the central nervous system a rest. Cheating arises when one uses a weight that is too heavy for them to lift, but go ahead to lift the weight and forgo form to do it. This not only confines the gains one can make, but can cause injuries. Lifting heavy weights while still young can lead to premature growth plates (epiphysis). The website goes ahead to explain how low rep ranges prepare muscular strength, which in turn helps little in increasing muscular size. The site has helped me realize that not all people are the same and should not therefore copy another person’s routine so as to get the same results. Another important thing I have learnt from the site is that one does not necessarily need to fast to achieve his/her goal. When you starve yourself, the body holds onto any fat it has, therefore, one will lose muscle instead which is very unhealthy. One should also not neglect carbohydrates and fats in their foods as well as relying so much on the supplements. Finally, it is important that before embarking on weight training, one should undertake extensive research to facilitate attainment of his or her goals. Remember nothing takes place immediately and one should be
