International Students Should Be Taught At A University

International students who come from different parts of the world to study with later hopes of finding a job, take loans to help pay for education ending up in large debts. This sadly is a harsh reality for students who come as international students into the United States. International students are not permitted to work off campus while studying at a university. According to the U.S. Citizenship Immigration Services, visas granted to foreign students are prohibited to any execution of a job (Working). This can include any work ranging from working in motels and liquor stores to in some cases, on campus. Inability to abide by these rules can result in deportation or can affect the student visa and further permissions for a work visa and a green card. Making it incapable for international students to work off-campus, builds a financial burden on these students as well as their parents back home. Not only are these students burdened with thousands of dollars of debt, the currency exc hange rate makes it tougher for these students to pay for their tuitions, housing, and food, without earning it in American dollars. Some students are fortunate enough to find and do jobs on campus, but only small number of students admitted in United States universities are hired for on-campus and the availability is quite low in comparison to a number of international students. This makes it difficult for international students to get an on-campus job and help pay their tuitions, as well asShow MoreRelatedInternational Students At The American University1749 Words   |  7 PagesHow many of you guys study well in the American Universityï ¼Å¸ Maybe some of you have problem in your academic study?

The Emergence of Two Types of Jews in the United States

However, this fear of covert discrimination in the workforce did not help those already drifting from Jewish ideology and heritage from drifting even further. With the 1950’s nearing its end, education and acceptance in American society was more prevalent on the public’s radar. With those of the first generation still holding to their Jewish identity, many of their children were less motivated and less caring for their Jewish roots. This lack of awareness tainted Jewry of the fifties and climactically corroborated this Jewish emergence and assimilation to surpass throughout the sixties. The beginning of the 1960’s for American Jewry showed no difference in motivation than the previous decade. The choices made over the next two decades accurately convey a path for the emergence of two types of Jews in America. In a New York Times article written in 1962, Rabbi Rosenblum expresses his concern for Jews during this time. He says, â€Å"What we Jews wants is what others desire, just to be let alone to enjoy life liberty, and happiness along with our neighbors.† It marked a point of realization that if Jews uniformly wanted to assimilate without conflict, this could be achieved. The question however still remained whether this could be done while also retaining a Jewish identity.

Corporate Financial Management for Budgeting -myassignmenthelp

Question: Discuss about theCorporate Financial Management for Capital Budgeting. Answer: Introduction Capital budgeting decisions are also called investment decision which affects finance position related to fixed assets of the firm in long run. The capital budgeting decision is based on cost and benefits analysis and these techniques helps in evaluating the suitability of a project. The criterion is selected on basis of maximizing market value of the organization. The finance manager of an organization has to take two decisions such as short term decision and long term decision regarding their capital structure. Short term decisions are called working capital decision whereas long term decisions are called capital budgeting decision (Smit, 2007). In this context, the present report aims to demonstrate the impact of capital budgeting techniques on management decision-making of a business entity. Relation between management decisions making to capital budgeting techniques The capital budgeting decisions are based on basic three criterions that are, accept- reject decision, mutually exclusive decision and capital rationing decision. The accept reject criterion is related to independent projects which means a single project and cannot be compared with another project. The business organizations can accept or reject a project on the basis of minimum rate of return in this criterion. For example in minimum rate on investment is required by the organization is 10% and project can generate 11% rate of return then that project can be accepted. On the other hand, mutually exclusive decisions helps the management to take the decision among all the different projects in that case acceptance of one project automatically rejects all other projects on the basis of cost benefits analysis. The capital rationing decision is those decision under which capital is distributed amongst the acceptable projects because the management can distribute whole money in all the pr ojects due to limitation of resources (Moyer, McGuigan and Rao, 2014). The capital budgeting techniques are divided in two parts: Traditional techniques Modern techniques Traditional techniques: These techniques are also known as unadjusted time methods because these techniques do not consider present value of money. The acceptance or rejection of projects by management in case of this technique depends upon future cash inflows of project, if future cash inflows are more than present investments than project can be accepted otherwise it is rejected. There are three techniques under this method: Urgency Method: This technique is based on assumption that project which requires immediate action should be taken first and that cannot be postponed. For example if in a factory, a machine stops working and requires immediate repair works for Rs. 10,00,000 for continuing the production then management will spend such amount for continuation of projects without considering profitability of the project. Pay- Back period Method: Under this method that project is accepted which recovers the cost of investment as early as possible. It means this technique helps the management to select a project which recovers its cost as early because future is uncertain. Average rate of return: The management of an organization always calculate minimum rate of return on an investment that depends upon internal and external factors of the organization. If any investment proposal which can earn more than minimum rate of return that project can be accepted (Otley and Emmanuel, 2013). Modern Techniques/ Discounted cash flow techniques: These techniques consider present value of money i.e. future cash inflow is discounted in terms of present value. These techniques are: Net present value method: These techniques may be defined as difference between present value of future cash inflows and present value of cash outflows. This technique helps the management to accept or reject the project based on positive net present value i.e. present value of cash inflow is more than present value of cash outflow. The minimum rate of interest for discounted cash flows is selected. Present value index or profitability index: This technique is based on ratio of present value of cash inflow and present value of cash outflow. This is known as profitability index, if profitability index is more than one then project can be accepted otherwise it is rejected. This helps the management to decide cash inflow receivable from the project in comparison with investment in project. Internal Rate of return method: It is rate of return where NPV is zero which means present value of cash inflow is equal to present value of cash outflow. The business can decide its break even point where no profit or loss situation where inflow is equal to outflow and projected can be accepted without any loss. Discounted Pay- Back period method: Under pay back period method that project can be accepted which recovers the cost as early as possible but in this techniques future cash inflow and outflows are discounted according to the rate of interest and decision is taken. This technique helps the management early recovery of cost after considering present value of money. Terminal Value method: In this technique it is assumed that each cash inflow is reinvested immediately by an organization to generate the interest or other income. This is because reinvested cash inflow in different income bearing securities generates the compounded return to an organization which in turn provides higher return of a project (Weygandt, Kimmel and Kieso, 2009). Discounted cash flow techniques Break Even Analysis: This refers to a situation where a business realizes no profit or loss, i.e. it is level of sales where total revenue is equal to total cost. In the present competitive business environment, there is huge competition in the market where cost and selling price of the product is variable and thus management desires to achieve its breakeven point as early as possible for realizing profits. . The future is uncertain and thus management has to develop effective strategies for realizing its breakeven point and have to develop their capital structure adequately. It is always interested to decide that level of sales which can recovers at least variable cost of product. The capital budgeting techniques helps the organization with various techniques such as net present value, internal rate of return etc. According to NPV criterion the management can achieve break even points where NPV is zero. Internal rate of return techniques helps the management to accept the project where the project is ea rning at least minimum rate of return on the project (Moyer, McGuigan and Rao, 2014). Sensitivity Analysis: The various variables related to investment proposal involved different variable such as cost, market share, sales volume, selling price. The projected cash flow depends upon these variables and these variables are uncertain due to time factor and customer choices and technological development. This technique of capital budgeting force the management to identify the variables that effect the cash flow of the project and guide the management to take the right action for this variable. This technique provides the facility to the management to concentrate on the effect of change in cost, sales or other factor on the outcome of the project. The future is uncertain and management is expected to achieve desired results due to cost involved in the project. The sensitivity analysis helps in identifying how sensitive are the various estimated variables of a project. It shows how sensitive is a projects NPV or IRR for a given change in particular variables. This approach guide the management how far sales, cost and other data can affect the outcome of a project because if the cost of project decline then it will generate more cash inflows and vice versa. Under this technique, it is assumed that only one variable is changed and others are constant. If the sales of an organization increase, the inflow of a project also increases and vice- versa. In that case one variable is changed but other variable are constant. This can be done by different approaches such as optimistic approach, pessimistic approach and expected approach. Under this technique, assumption about sales are changed one time and other factors are constant and on other side sales are constant but other factors such as cost can be changed. These techniques help the management to evaluate the project according to different criterion so the management can estimate of outcome in future because of change in sales or other factors (Weygandt, Kimmel and Kieso, 2009). Scenario analysis: This is the situation where more than one variable is changed at the same time and no variable is constant. This situation is very tedious for the management where all the factors related to a project is changed simultaneously and affect the outcome of a project. If all the variables related to a project are changed in the positive direction then it is beneficial for an organisation as it will generate more cash inflows for management. However, in reverse case if all the variables are negative it provides negative results for an organisation. This evaluates the expected value of a proposed investment or business activity. The statistical mean is the highest probability event that can be expected in a certain situation. By creating various scenarios that may occur and combining them with the probability that they will incur, an analyst can better determine the value of an investment or business venture. The major drawback for these types of fixed outcome analyses are the probabilities estimated and the outcome sets bounded by the values for the extreme positive and negative events (Otley and Emmanuel, 2013). Simulation Techniques Sensitivity analysis and scenario analysis are quite useful to understand the uncertainty of the investment projects. However, these methods do not consider the interactions between variables and also, they do not reflect on the probability of the change in variables. The future is uncertain due to market choices, customer preferences, competition, technological development and market driven forces. Thus, it is essential for an organization to take effective capital budgeting decision for the objective of investment in the long run. In the situation of uncertainty, simulation techniques are more beneficial for the finance manager, because future is uncertain about cost, revenue and returns of the projects (Baker, 2011). Under this method statistical distribution such as probability distribution is allowed for each outcome of project. This technique is based on computer and reflects real time situations. This technique is known as monte-carlo simulation model. The term Monte Carlo implies that the approach involves the use of numbers drawn randomly from probability distributions. Under the simulation techniques computer generates the random numbers for each of the variables such as market share, sale price, variable cost etc. This process of randomization is attempted for lot of time to judge the expected net present value from the different factors. This process allows the management to use different calculation which is based on different factors to take possible outcome of projects under uncertainty. The management then calculates the expected net present value that is associated with standard deviation to judge the level of risk involved in project (Smit, 2007). Conclusion It can be stated from the overall discussion that all the above mentioned techniques of capital budgeting facilitates the calculation for highly complex and multi variable based investment proposal. This in turn helps the finance manager to take right decision for feasibility of a project. However, the capital budgeting techniques are not feasible in all circumstances because probability of different factors cannot be exactly measured. The capital budgeting model is also very tedious, time consuming and involve huge expenditure on the part of management. References Baker, H.K. 2011.

Nigerias Economic Crisis

Introduction Nigeria has a dual economy and, its population relies on earnings from the energy sector followed by the agricultural sector. In 1960, agriculture became the country’s main source of revenue accounting for nearly half of the country’s Gross Domestic Product (GDP).Advertising We will write a custom research paper sample on Nigeria’s Economic Crisis specifically for you for only $16.05 $11/page Learn More The emergence of oil and other petroleum products has increased the country’s foreign exchange earnings hence the increased revenues. Nigeria is endowed with large quantities of natural resources, both renewable and non-renewable. For instance, it is endowed with oil and natural gas reserves with crude oil being estimated at around 35 billion barrels. The country, however, cannot meet the needs of its large population and this is an extraordinary macro-economic phenomenon. The country’s economic growth is un predictable and it now depends on imported food though it was once a net exporter. This is quite surprising keeping in mind that Nigeria is rich in natural resources especially energy and is the sixth largest producer of crude oil internationally (Ekpo, 2008). This paper will discuss the causes of Nigeria’s economic crisis, its effects and finally, how the phenomenon can be changed. Discussion Causes of Nigeria’s Economic Crisis Consumers, producers, and efficiency of the market The decline in Nigeria’s economic growth can be attributed to market shortages of its petroleum products especially Kerosene and diesel. The weak political demands exerted by the poor kerosene and diesel customers and the limitations on public financing of imports is what has led to the market shortages. The country has five government owned oil refineries, which are capable of producing about 500 barrels of oil every day. The high oil production capacity with no adequate markets has mad e the country’s government to get involved in importing large volumes of food to remedy the shortages involved. Supply and Demand Nigeria’s economic crisis can be attributed to the interaction of demand and supply in the market. The citizens are over reliant on self-generated electrical energy despite the fact that the nation is rich in energy resources. The country’s electricity market, which on the supply side is controlled by National Electric Power Authority (NEPA), is incapable of providing acceptable electricity standards, which are both reliable and accessible. The poor record in electricity supply has led to high losses hence the nation’s economic crisis. Price fluctuations in the global oil industry and poor macro- economic organization especially the country’s failure to expand its economy are other key contributors to its economic problems. The diversity of economic and non-economic goals without proper recognition of tradeoffs has also resulted to the crisis. This is seen in its pricing strategies in the global market. Institutional and administrative failures, which have led to production inefficiencies and increased operating costs, have led to the extraordinary macroeconomic phenomena in Nigeria (Oluyemisi, 2010).Advertising Looking for research paper on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Effects of Nigeria’s Economic Crisis The constant disequilibrium in the country’s market for petroleum products has negatively affected the living standards of the citizens. Poverty levels have increased with majority of people in the country living on not more than $2 in a day. Nigeria’s economic crisis has greatly deteriorated its industrialization process and this has significantly decreased its effort to achieve a stabilized economy. Competitiveness of the countries local industries in both regional and international markets has been reduced and many citizens are now unemployed (Iyoha Itsede, 2002). Changing Nigeria’s Economy Mankiw’s 10 principles Nigeria’s economic theory suggests that energy and oil purchases depend on price of other related products such as natural gas and petrol. The country’s macroeconomic phenomenon can be solved through Mankiw’s ten economic principles. According to Mankiw, countries face tradeoffs and to achieve their goals, then they have to surrender some things. Consequently, for successful decision-making, the country has to trade off one objective against another. Mankiw’s second principle states that what is surrendered in an attempt to achieve something is its cost. The country while getting out of its problems has to put into consideration the total costs required. The third principle elaborates the idea that wise people reason at the margin and, only take action if the subsidiary benefits exceed the costs. Nigerians living standa rds have changed due to low benefits and this can be explained using the principle that people react to changes in incentives. While trying to explain how the economy works together as one, Mankiw says that trade can make the nation to be better placed. Through trade, Nigeria can be able to concentrate on its best activities and other nations can purchase different goods from them. Nigeria can thus solve its economic problems by participating in market economies since through this it can distribute its resources more effectively (Mankiw, 2012). According to Mankiw, the government can at times enhance market outcomes. For instance, since Nigeria has not been able to use its resources effectively, then its government should participate in solving the issue through public policies such as setting rules against monopolies. In his eighth principle, Mankiw states that the standard of living in any nation depends on the nation’s capacity to produce goods and services. To get out of its economic problems, Nigeria should ensure that its workforce produce goods and services in large quantities.Advertising We will write a custom research paper sample on Nigeria’s Economic Crisis specifically for you for only $16.05 $11/page Learn More This could lead to high living standards since productivity in a country increases with increasing income. Mankiw’s ninth principle talks of the fact that prices of goods in a country increase as the government gets involved in printing excess money. Nigeria should not involve herself in such actions since this could lead to low currency values. Sequentially, prices would increase and this would call for more money used in purchasing goods and services. Mankiw’s last principle states that a nation faces a short run transaction during times of price increases and unemployment. Though lowering of prices leads to high unemployment levels, Nigeria should try this principle since it leads to an understanding of the short-term effects of fluctuations in taxes, government expenditure, and monetary principles (Mankiw, 2012). Government Policies Substantial expansion in the value and quantity of Nigeria’s natural resources is important in sustaining its economic growth, creating employment, reducing poverty, and finally improving the well-being of its population as a whole. Overcoming the country’s economic crisis and ensuring global standards in quantity, value and consistency of the nation’s services is a prerequisite for attaining the government’s desire of being one of the top 20 economic countries by 2020. To improve its economy, Nigeria should adopt a new policy with new principles that will lay the basis for continuous improvement in other fields such as agriculture. It should create a more favorable macro-environment that encourages the private sector to put more investments in agriculture. The duties of the government together with t hose of the private sector should be rationalized in a manner that stimulates agricultural development. The institutional structure should also be reorganized to allow for government intervention in the sector since this would lead to growth of the agricultural sector. The government should further articulate and execute development programs in the rural areas to improve the standards of living of the locals. The amount of budgetary allocation given to the agricultural sector should be increased to improve agricultural productivity. Finally, best practices should be developed and procured in the country’s oil and energy industries (Ajilima Kwanashie, 1998). Taxation The government should rectify irregularities in import and export tariffs especially in petroleum and agricultural products. It should also promote the use of machinery in agriculture through imposing constructive tariff policies. This would ensure that the country does not depend on imported food (Mankiw, 2012).

However, the phenomenon of price elasticity has been synchronized in Nigeria for quite a long time. Price elasticity in Nigeria is determined by consumer demand irrespective of price increases (Oluyemisi, 2010). Conclusion Nigeria is among the richest countries in the world though most of its citizens are strikingly poor. This is because the country relies on its energy sector as the only source of revenue without diversifying in other fields. It is, therefore, clear that for the country to have adequate resources to meet the needs of its population, it should get involved in other income generating activities such as agriculture. The government should also come up with policies that clearly define the duties and responsibilities of both the central government and the private sector in order to get rid of the country’s economic crisis.

Learn VBA Macro Coding Word 2007

Learn VBA Macro Coding Word 2007 The goal of this course is to help people who have never written a program before learn to write one. Theres no reason why office workers, homemakers, professional engineers and pizza delivery persons shouldnt be able to take advantage of their own hand crafted custom computer programs to work faster and smarter. It shouldnt take a professional programmer (whatever that is) to do the job. You know what needs to be done better than anyone else. You can do it yourself! (And I say this as someone who has spent many years writing programs for other people ... professionally.) With that said, this is not a course in how to use a computer. This course assumes that you know how to use popular software and in particular, that you have Microsoft Word 2007 installed on your computer. You should know basic computer skills like how to create file folders (that is, directories) and how to move and copy files. But if youve always wondered what a computer program actually was, thats OK. Well show you. Microsoft Office isnt cheap. But you can get more value from that expensive software you already have installed. Thats a big reason we use Visual Basic for Applications, or VBA, along with Microsoft Office. There are millions who have it and a handful (maybe no one) who uses everything it can do. Before we go any further, however, I need to explain one more thing about VBA. In February 2002, Microsoft made a 300 billion dollar bet on a totally new technology base for their entire company. They called it .NET. Since then, Microsoft has been moving their entire technology base into VB.NET. VBA is the very last programming tool that still uses VB6, the tried and true technology that was used before VB.NET. (Youll see the phrase COM based to describe this VB6 level technology.) VSTO and VBA Microsoft has created a way to write VB.NET programs for Office 2007. Its called Visual Studio Tools for Office (VSTO). The problem with VSTO is that you have to buy and learn to use Visual Studio Professional.  Excel itself is still COM based too and .NET programs have to work with Excel through an interface (called the PIA, Primary Interop Assembly). So ... until Microsoft gets their act together and gives you a way to write programs that will work with Word and doesnt make you join the IT department, VBA macros are still the way to go. Another reason we use VBA is that it really is a fully baked (not half baked) software development environment that has been used for years by programmers to create some of the most sophisticated systems in existence. It doesnt matter how high your programming sights are set. Visual Basic has the power to take you there. What is a macro? You may have used desktop applications that support what is called a macro language before. Macros are traditionally just scripts of keyboard actions grouped together with one name so you can execute them all at once. If you always start the day by opening your MyDiary document, entering todays date, and typing the words, Dear Diary, Why not let your computer do that for you? To be consistent with other software, Microsoft calls VBA a macro language too. But its not. Its much more. Many desktop applications include a software tool that will let you record a keystroke macro. In Microsoft applications, this tool is called the Macro Recorder, but the result is not a traditional keystroke macro. Its a VBA program and the difference is that it does not simply replay the keystrokes. A VBA program gives you the same end result if possible, but you can also write sophisticated systems in VBA that leave simple keyboard macros in the dust. For example, you can use Excel functions in Word using VBA. And you can integrate VBA with other systems like databases, the web, or other software applications. Although the VBA Macro Recorder is very useful for simply creating simple keyboard macros, programmers have discovered that its even more useful to give them a running start in more sophisticated programs. Thats what were going to do. Start Microsoft Word 2007 with a blank document and get ready to write a program. The Developer tab in Word One of the first things that you have to do to write Visual Basic program in Word 2007 is find Visual Basic! The default in Word 2007 is to not display the ribbon that is used. To add the Developer tab, first click the Office button (the logo in the upper left corner) and then click Word Options. Click Show Developer tab in the Ribbon and then click OK. When you click the Developer tab, you have a whole new set of tools used to write VBA programs. Were going to use the VBA Macro Recorder to create your first program. (If the ribbon with all your tools keeps disappearing, you might want to right-click the ribbon and make sure Minimize the Ribbon is not checked.) Click Record Macro. Name your macro: AboutVB1 by typing that name in the Macro Name textbox. Select your current document as the location to store your macro and click OK. See the example below. (Note: If you pick All Documents (Normal.dotm) from the drop down menu, this test VBA program will, in effect, become a part of Word itself because it will then become available for every document you create in Word. If you only want to use a VBA macro in a specific document, or if you want to be able to send it to someone else, its a better idea to save the macro as part of the document. Normal.dotm is the default so you must change it.) With the Macro Recorder turned on, type the text, Hello World. into your Word document. (The mouse pointer will change into a miniature picture of a tape cartridge to show that keystrokes are being recorded.) (Note: Hello World is almost required for a First Program because the very first programming manual for the early computer language C used it. Its been a tradition ever since.) Click Stop Recording. Close Word and save the document using the name: AboutVB1.docm. You have to select a Word Macro-Enabled Document from the Save as Type dropdown. Thats it! You have now written a Word VBA program. Lets see what it looks like! Understanding what a VBA program is If you have closed Word, open it again and select the AboutVB1.docm file that you saved in the previous lesson. If everything was done correctly, you should see a banner at the top of your document window with a security warning. VBA and Security VBA is a real programming language. That means that VBA can do just about anything you need it to do. And that, in turn, means that if you receive a Word document with an embedded macro from some bad guy that macro can do just about anything too. So Microsofts warning is to be taken seriously. On the other hand, you wrote this macro and all it does is type Hello World so theres no risk here. Click the button to enable macros. To see what the Macro Recorder has created (as well as to do most other things that involve VBA), you need to start the Visual Basic Editor. Theres an icon to do that at the left side of the Developer ribbon. First, notice the left hand window. This is called the Project Explorer and it groups together the high level objects (well talk more about them) that are part of your Visual Basic project. When the Macro Recorder was started, you had a choice of the Normal template or the current document as a location for your macro. If you selected Normal, then the NewMacros module will be part of the Normal branch of the Project Explorer display. (You were supposed to select the current document. If you did select Normal,  delete the document and repeat the previous instructions.) Select NewMacros under Modules in your current project. If there still isnt any code window displayed, click Code under the View menu. The Word document as a VBA container Every Visual Basic program must be in some kind of file container. In the case of Word 2007 VBA macros, that container is a (.docm) Word document. Word VBA programs cant run without Word and you cant create standalone (.exe) Visual Basic programs like you can with Visual Basic 6 or Visual Basic .NET. But that still leaves a whole world of things you can do. Your first program is certainly short and sweet, but it will serve to introduce the major features of VBA and the Visual Basic Editor. The program source will normally consist of a series of subroutines. When you graduate to more advanced programming, youll discover that other things can be part of the program besides subroutines. This particular subroutine is named AboutVB1. The subroutine header must be paired with an End Sub at the bottom. The parenthesis can hold a parameter list consisting of values being passed to the subroutine. Nothing is being passed here, but they have to be there in the Sub statement anyway. Later, when we run the macro, we will look for the name  AboutVB1. There is only one actual program statement in the subroutine: Selection.TypeText Text:Hello World! Objects, methods and properties This statement contains the big three: an objecta methoda property The statement actually adds the text Hello World. to the contents of the current document. The next task is to run our program a few times. Just like buying a car, its a good idea to drive it around for a while until it feels a little bit comfortable. We do that next. Programs and documents We have our glorious and complicated system ... consisting of one program statement ... but now we want to run it. Heres what thats all about. Theres one concept to be learned here that is very important and it often really confuses first timers: the difference between the program and the document. This concept is foundational. VBA programs have to be contained in a host file. In Word, the host is the document. In our example, thats AboutVB1.docm. The program is actually saved inside the document. For example, if this was Excel, we would be talking about the program and the spreadsheet. In Access, the program and the database. Even in standalone Visual Basic Windows application, we would have a program and a form. (Note: There is a trend in programming to refer to all high level containers as a document. This is specifically the case when XML ... another up and coming technology ... is being used. Dont let it confuse you. Although its a slight inaccuracy, you can think of documents as being roughly the same as files.) There are ... ummmmm .... about three main ways to run your VBA macro. You can run it from the Word Document.(Note: Two subcategories are to select Macros from the Tools menu or just press Alt-F8. If you have assigned the macro to a Toolbar or Keyboard shortcut, thats one more way.))You can run it from the Editor using the Run icon or Run menu.You can single-step through the program in debug mode. You should try every one of these methods just to become comfortable with the Word/VBA interface. When you finish, you will have a whole document filled with repeats of Hello World! Running the program from Word is fairly easy to do. Just select the macro after clicking the Macro icon under the View tab. To run it from the Editor, first open the Visual Basic editor and then either click the Run icon or select Run from the menu. Heres where the difference between the Document and the Program might become confusing to some. If you have the document minimized or perhaps have your windows arranged so the editor is covering it, you can click the Run icon over and over and nothing seems to happen. But the program is running! Switch to the document again and see. Single stepping through the program is probably the most useful problem solving technique. This is also done from the Visual Basic editor. To try this out, press F8 or select Step Into from the Debug menu. The first statement in the program, the Sub statement, is highlighted. Pressing F8 executes the program statements one at a time until the program ends. You can see exactly when the text is added to the document this way. There are a lot of more refined debugging techniques such as Breakpoints, examining program objects in the Immediate Window, and the use of the Watch Window. But for now, simply be aware that this is a primary debugging technique you will use as a programmer. Object Oriented Programming The next class lesson is all about Object Oriented Programming. Whaaaattttt! (I hear you moaning) I just want to write programs. I didnt sign up to be a computer scientist! Fear Not! There are two reasons why this is a great move. First, in todays programming environment, you simply cant be an effective programmer without understanding object oriented programming concepts. Even our very simple one-line Hello World program consisted of an object, a method, and a property. In my opinion, not understanding objects is the biggest single problem beginning programmers have. So were going to confront the beast right up front! Second, were going to make this as painless as possible. Were not going to confuse you with a load of computer science jargon. But right after that, were going to jump right back into writing programming code with a lesson where we develop a VBA macro that you can probably use! We perfect that program a little more in the next lesson and finish up by showing you how to start using VBA with several applications at one time.

The Experiment on the Coastal Engineering to Analyse the Wave Lab Report

The Experiment on the Coastal Engineering to Analyse the Wave Behaviour and Linear Theory - Lab Report Example The thickness is always twice the diameter of the concrete armor unit for the tetrapod layers Concrete. 20 The experiment on coastal engineering was carried out in the hydraulics laboratory for approximately two hours. This experiment consisted of two parts. Part one was linear wave theory and part two was breakwater design. The venue of the experiment was Sopwith building Waves are created when the wind blows on top of the sea and the bottom layer receives frictional drag from the surface of the sea which exerts frictional drag to the next wind layer above it. This process continues in all the wind layers. The coastal zone is very important to the community around it. For the community to survive, the engineers play a big role in protecting this zone against flooding, erosion, and destruction of property by the ocean waves and tides. The laboratory work is important in that to avoid all these natural disasters. The measurements lead to commendation on how the waves acted on the coast and how they were reflected on the vertical wall. The waves that are reflected on the vertical surface had no horizontal movement and are referred to as standing waves. A rubble mound breakwater was created to make the wave to move over its Smaller waves with period 1.0s, were created to come to the conclusion about how they affect the model structure. This observation ended when the rubble mound breakwater finally failed. The wave height of a surface wave is the difference between the elevations of a crest (the highest point of the wave) and a neighboring trough (the lowest point of the wave) as it is shown at the figure below. (Dr. Alan Dykes, 2011).  

What It Takes to Be a Volunteer Article Example | Topics and Well Written Essays - 500 words

What It Takes to Be a Volunteer - Article Example I thoroughly enjoyed the experience because it made me feel special as I was able to impart that special feel within the lives of the people themselves. I found out that by doing good, the conscience gains quite a great deal of satisfaction as it is something that makes me feel satisfied with who I am and what I want to give back to the society in more ways than one. The socio-economic development that took place in Haiti during this time was immense. I learned quite a few aspects related to the socio-economic development domains as these have been very dear to me now. I found out that I can grow my capacity building domains as these had the power to find new pathways and thus translate success into a language of its own in the most basic sense. More than anything else, I aspire to seek my own success through the steps that I undertook and which I plan on taking in the coming times as well, and not just remain limited to the Haiti experience in the sheerest sense. The socio-economic development in times of peace and security are therefore some of the more significant pointers that I will derive from the entire experience of being a volunteer in Haiti. It gave me immense satisfaction to know that I belonged amongst the people who could do something or the other for the people who were in distress and who required a hand at the end of the day, no matter how small the effort turned out to be (Kelloway, 2001). I am of the opinion that some possible ways of encouraging volunteerism are through finding pathways through which the related individuals are contacted so that they can give their best towards the societal domains. This will help them shape up in a better manner than they ought to be without the volunteering role coming to the fore.

Conventional cryptography Essay Example for Free

Conventional cryptography Essay Conventional cryptography uses identical secret â€Å"key† in both message encrypting and decrypting. Secret key cryptography often times having difficulty securing key management usually in opens systems with large numbers of users (RSA Lab, n. d. ). Diffie and Hellman initiated the concept of public-key cryptosystems in 1976, to work out the problems with key management. (RSA Lab, n. d. ) The newly created concept of public-key cryptosystems employs encryption and digital signatures. The public-key cryptosystem works by providing each person a pair of keys, a public-key, and a private-key. The advantage of using public-key is you can send out classified information publicly but it cannot be decrypted. Safely, the recipient that holds the private key is doing the decryption. The form the holds the security information for both sender and receiver is called a certificate. Public-key certificate The Public-key cryptosystems principal ingredients in realizing its security tasks are: 1) Issuer – holds the public-key and the compulsory signed private key. It is the basis of the certificate. Issuer can be anyone with a public key and a private key. 2) Subject- contains public key, value, or name. The subject is receiver of the certificate. The particular recipient in this field has exclusive rights to view the certificate. 3) Delegation- this field contains a Boolean value providing the subject with rights to re-delegate the certificate. If the field is false, the subject may not pass or delegate the certificate to other subject. 4) Authorization- it restricts the subject access rights to a specific information, data, and locations. These rights may be given depending on applications and the level of security required. 5) Validity dates specify the validity period of a certificate by an issuer. It limits the duration of access of the subject. Sample transaction process of public-key cryptosystem. The sample above shows Ka as the issuer, Kb as the subject, True as Boolean value to allow the subject to re-delegate the certificate, Authorization to read file in â€Å". \john\documents,† and certificate validity dates from 02/10/2006 to 02/12/2006. John with a Public-key (Ka) issued a certificate to subject Dianne (Kb). The certificate is sign by Johns private key, when Dianne wants to read and write files in John’s document directory, request will be written, signs it with his own private key, and send it. When the file server gets the request and found Johns (Ka) signed private key, then the request is granted. The server will now allow Dianne to read and write files in John’s documents directory until the validity date specified in the certificates validity field expires. The delegation occur when the Boolean field is mark True, Kb can now impart its right to other subject. Let us call the new public-key as Kc. Kb re-delegate its certificate to Kc and signs a new certificate for Kc at the same time. Kc now has two certificates, which form a chain.

The Uncontrolled Ambition of Macbeth and Lady Macbeth Essay -- Macbeth

The Uncontrolled Ambition of Macbeth and Lady Macbeth      Ã‚   There is basically uncontrolled ambition throughout William Shakespeare's tragic drama Macbeth. In this essay we will explore numerous examples of this on the part of the two protagonists, Macbeth and Lady Macbeth.    Blanche Coles states in Shakespeare's Four Giants that the protagonist's ambition was not the usual narrow, personal ambition:    He has admitted to a vaulting ambition. We have no other evidence of personal ambition except, possibly, his own word in this speech. Onrushing events crowd the thought out of his mind and out of our view. We do have ample evidence of his ambition for his family, ambition for a son who might succeed him. [. . .] We think normally of ambition as a personal thing, but it is not always so. Macbeth's stupendous imagination, as revealed later in the play, gives him a breadth of vision altogether out of keeping with a narrow, personal ambition. (50-51) Samuel Johnson in The Plays of Shakespeare explains the place of ambition in this tragedy:    The danger of ambition is well described; and I know not whether it may not be said in defence of some parts which now seem improbable, that, in Shakespeare's time, it was necessary to warn credulity against vain and illusive predictions. The passions are directed to their true end. Lady Macbeth is merely detested; and though the courage of Macbeth preserves some esteem, yet every reader rejoices at his fall. (133)    In "Memoranda: Remarks on the Character of Lady Macbeth," Sarah Siddons mentions the ambition of Lady Macbeth and its effect:    [Re "I have given suck" (1.7.54ff.)] Even here, horrific as she is, she shews herself made by ambition, b... ...iion of Critical Essays.

Smooth Talk

â€Å"Smooth Talk† is a film adapted from the short story â€Å"Where are you going? Where have you been?† by the author Joyce Carol Oates. The short story was first published on 1966 while the film was released on 1985. The protagonist â€Å"Connie† in the short story was a fifteen year old young lady who has two sides of herself; one side if for her home and the other is for outside her home or anywhere else aside from home. Connie’s sister named June is the opposite of her. While June is being praised by her mother which is also different from Connie, Connie on the other hand was a young girl who enjoys the company of her girl friends. Together with her girl friends, they enjoy watching movie or have a walk to shopping plaza. In the short story written by Joyce Carol Oates, Connie’s character was described as a young girl who is concern with the way she looks. Her character was centered in her physical appearances and gestures and not so much of her attitude and feelings. It was evident in the short story when Joyce Oates describes Connie’s â€Å"quick, nervous giggling habit of craning her neck to glance into mirrors or checking other people’s faces to make sure her own was all right† (Joyce Carol Oates. 1966). The vulnerability of Connie’s character was very present in the story when Arnold Friend’s enters the picture and forces her to come with her. Arnold Friend is described as a â€Å"suspicious stranger† whom she saw once and suddenly knows almost everything about her and her family. Connie at a very young age was susceptible to Arnold Friend who wanted her to simply go out and have a ride with him. Her character in the short story define a weak young girl who faces a man she doesn’t even know and mocks her up until she get loose of everything on her mind. Joyce Oates was precise about Connie’s vulnerability when she describes how Connie helplessly tries to let go of Arnold Friend but vulnerably ends up with his arms. Indeed, the short story was in fact a manifestation of how powerless Connie was in terms of her handling Arnold Friend’s attitude towards her. Connie could have had done something but with her vulnerability as a young girl she gives up something of herself. On the other hand, â€Å"Smooth Talk† visually presented the short story to film. Connie’s character was evidently showed in the film as a young fifteen year old girl who flirts around with boys and loves to cruise the shopping malls with her friends. Connie’s character was expanded in the film, adding up some new things that were not mentioned in the short story. Nonetheless, Connie’s being vain and flirt was still evidently in the film. Her suspicious stranger was more powerful in the film seducing her with his smooth-talking way. In the film, Arnold Friend’s character involves sexual desire for Connie and his character was full of aggressiveness to seduce Connie. Connie on the other hand, is a young girl who is silly and flirtatious with other guys but come one Sunday morning when she was left alone at home and was confronted with the suspicious stranger, Connie’s vulnerability was evidently showed. Her character as a young girl who has two sides of herself was helplessly alone and afraid, trying to overcome Arnold Friend’s seduces. While she was trying to figure out what to do and how to let loose of the stranger, the smooth-talking man tries to seduce her and consistently tries to win her. Part of the film was entirely focused on the situation on which Connie was confronted by the stranger just like in the short story. Though there were some minimal  changes in the film that wasn’t mentioned in the short story, â€Å"Smooth Talk† by Tom Cole gave justice to Joyce Oates’s â€Å"Where are you? Where have you been?†. Connie’s character in the short story was more innocent than her character in the film. Although it was the same, her character in the film portrayed by Laura Dern was â€Å"lavishly and lovingly textured†. (Joyce Carol Oates. 2007) Basically, the mere fact that a short story is being read while the film was being watched evidently showed that Connie’s character of vulnerability was formulated both in the short story and in the film. It was clearly defined and translated in the sort story how Connie’s weak character gave her the risk of giving herself up for Arnold Friend. While in the film, both Connie and Arnold’s characters were emerged consistently as described in the short story. The vulnerability of Connie in the film is just somewhat the same in the short story. But Connie’s being naà ¯ve of the things that happens around her was clearly specified in the short story. Nevertheless, â€Å"Smooth Talk† and â€Å"Where are you? Where are you going?† is both a masterpiece in there own rights and abilities. The two is not only about the reality of a teenager growing up in a harsh world outside her home but also it imparted to us the idea of some issues that runs inside a family or inside home that most of us take for granted. The adaptation was visually presented well from the short story and just the same, both gave the justice on its own. Connie’s character provides us the imagination of how innocent and free spirited she was as a young girl that in the end lose herself to a man she doesn’t even know but who knows her very well. There lies the mystery or the story by Joyce Carol Oates. Works Cited Oates, Joyce Carol. â€Å"Where are you going? Where have you been?.† Celestial Timepiece A Joyce Carol Oates Home Page.

Alcohol should be made illegal once again essays

Alcohol should be made illegal once again essays Alcohol should be made illegal once again Alcohol is the worst drug, yet alcohol is the easiest drug to get because it is a legal substance. The usage of alcohol has been a controversial issue through out the American history. Beginning in the 1900s, alcohol was looked upon as evil, but is currently legal to use. Even though many people want alcohol to be an illegal drug, other people believe that it should remain legal to adults who are twenty-years of age or older. Furthermore people use the fact that alcohol positively helps the economy, while the opposite side views legalized alcohol as a life threatening drug which obviously is a negative affect. Most people who consume alcohol use it as a source of relaxation or entertainment, but consequently, consuming alcohol can lead to a life threatening disease, alcoholism. In the past, I used to consume alcohol almost on a daily basis, until I realized that it was holding me back from doing certain things like focusing on my education, arriving on time at my job, and having fun without drinking the alcohol. I believe that alcohol should be banned by law to all people because there are so many negative affects that are caused by the drug alcohol. Since there are extremely high rates in traffic fatalities and domestic violence that have significant connections with the offenders using alcohol, I strongly oppose the legalized, self deteriorating drug, alcohol. Having traffic fatalities are sad and unfortunate situations, but having the accidents occur because a person is intoxicated by a legal drug is completely horrible and immoral to society. Nobody should be a victim to such a horrific situation, therefore I believe that making alcohol illegal would reduce the risk of harm upon the innocent American society. Fatalities and abuse are both major issues that affect society in whole, therefore, everyone should be aware of ...

A Sweet Story About Marmalade

A Sweet Story About Marmalade A Sweet Story About Marmalade A Sweet Story About Marmalade By Sharon The other day I was watching the last episode of the Parkinson Show (a UK talk show), when Michael Caine told a story about the origin of the word marmalade. The word refers to a jelly like preserve, usually made of citrus fruits, in which bits of the fruit and rind are suspended. According to Michael Caine, the name comes into the English language via Mary Queen of Scots, who was visiting a French speaking country and fell ill. Marmalade was one of the dishes they brought to tempt her palate and the phrase she overheard constantly was Maam est malade (Madam is ill) which gave the name marmalade (and which, incidentally) is a great way to remember the correct spelling of the word. So I set out to find out if this could be true. Disappointingly, the etymological dictionaries tell a different tale. The word marmalade meant quince jam and comes into English via French and Portuguese, deriving from marmelo meaning quince. Further back, the origin is Latin and Greek, from terms meaning honey-apple, which was the fruit resulting from the grafting of an apple onto a quince. The mystery is solved, but I cant help preferring Michael Caines version. 😉 Want to improve your English in five minutes a day?

Presidential election of 2012 Essay Example | Topics and Well Written Essays - 2250 words

Presidential election of 2012 - Essay Example However, the Republican Party in support of Romney managed to maintain control of the house representation at 233 seats, while the democrats were the majority in the senate representation with 53 seats (BBC bbc.co.uk). The 2012 U.S. elections came at a time that required special attention due to slow economic recovery, and the New Jersey Superstorm Sandy that gave people an opportunity to criticize the existing leadership. The catastrophe had called for the previous Obama government and Democratic Party to act wisely, maintain balance, and a good image before the nation that paid close attention. The quick move taken by the President Obama with the New Jersey governor, Chris Christie of the Republican Party to provide aid to the affected East Coast society, benefitted President Barack Obama in gathering support from people of New Jersey, for handling the emergency with integrity. During the last days of the campaign, the two presidential candidates had to perfect their actions and im ages towards the New Jersey disaster but as usual, it was up to the voter to decide how they related and viewed the actions of both candidates. The disaster seemed to be the last determinant of the voters’ motivation in support of their favorable candidate. Mitt Romney in his campaign marked the last Tuesday to the elections as ‘Storm Relief Events’ where he took blankets and food to the affected victims, while Obama rescheduled his activities on the following Wednesday, forfeiting the valuable time he would have had campaigning for his re-election, to focus on immediate management of the crisis, talking with the affected society and viewing the storm damage one on one (Fischer, spiegel.de). This strategy was well rewarded for Obama who Acquired 58 % of the votes in the state of New Jersey (â€Å"US election 2012† telegraph.co.uk). 1. Social Welfare Politics in North America have had along history with differentiated support of the leading political partie s that seem to be divided along racial and religious voters. Certain people tend to be associated with Democratic Party and not republican, based on their religious belief and race which end up into political debates, and in turn affect the voting pattern. The 2012 U.S. elections had a major issue surrounding the personal religious identities of the two leading presidential candidates, which well connects with the divisive social issues within religious dimensions. According to Wade, the Republican Party has more support from the whites than black based on their catholic and protestant religious faith (thesocietypages.org). There was little support for the Republican from the blacks and religiously unaffiliated (see fig. 1). Fig. 1. Republican composition based on religion from Lisa Wade. ; â€Å"Religion and Race among Democrats and Republicans†; thesocietypages.org. 15 September, 2012; Web; 12 November, 2012. On the other hand, democrats have most of their stronghold from t he societies dominated by black people and those religiously unassociated than in republican support (Wade thesocietypages.org ). Certain issues like permission of same sex marriages, the legality of abortion, inclusion of the word God on Parties platform and critical controversy of the Muslim video, set the differences between the parties and their support (see fig. 2).

Organisations and Behaviour Essay Example | Topics and Well Written Essays - 3000 words

Organisations and Behaviour - Essay Example The company was established in the year 1846. It is a listed company in the London Stock Exchange. 1.1 Organizational Structure and Culture and its Impact on the Performance of the Businesses The organizational structure has a great influence on the performance of the organization. The organization structure is considered as the anatomy of an organization, offering a foundation lying within which the organization performs its functions. This organization structure affects the behaviour of the organizational members. The organizational structure of BT Plc is based on two main internal divisions named BT Operate and BT Design. These two divisions support the rest four ‘customer facing’ divisions of the organization. BT Operate has the responsibility of deployment and operation whereas BT Design has the responsibility related to the design and the development of services. The divisions help the organization in delivering ‘software driven products’ associated wi th the next generation network and also achieve the target of cost savings. The organizational structure helps in the systematic functioning of the business operations. ... BT Plc is an integrated company with two main departments. In both the departments, separate procedures are conducted for the completion of the business processes. The organization has a huge scope of proving its excellence in the future as well. The values, policies, collection of traditions, attitudes and beliefs constitute the organizational culture of BT Plc. High values encourage the employees and increase their efficiency thereby increasing the performance of the organization (Yeo and Li, 2011). Ryan Air Ltd being one of the low cost airlines in Fingal, Ireland possesses a functional organizational structure. It is one of the most successful examples of the low cost business models. There are different levels of management. The values act as the core of the organization including reliability, quality, action, feedback and informal communication. The functional organization structure separates the series of activities in different segments. Ryan Air Plc changes the organizationa l structure by expanding the business operations for the allocation of responsibilities to all the employees in appropriate manner. The main success behind the successful organization structure is the coordination in different departments within the organization. The organization was launched with the aim to achieve the low cost leadership model. But at the same time, Ryan Air Ltd did not want that the name of the organization to get associated with anything cheap. The airline has built and maintained a work culture which is said to be an exciting place to work in. The cost cutting strategies are implemented in each and every aspect of the organization. The employees in the organization are awarded for their excellent performances and at the same time, reprimanded on

How Does Diversity and Immigration Impact Innovation?

How Does Diversity and Immigration Impact Innovation? Anca Pop Nowadays, due to the increasingly competitive economic environment, and the constant danger of economic turn-downs, innovation has come into great prominence not only as an important source of competitive advantage, but also as a powerful driver of economic growth and prosperity. In this new context, attention has been drawn to the role that cultural diversity and immigration play in fostering innovation. Thus, the aim of this essay is to assess the impact of immigration on innovation. Furthermore, the question regarding whether or not a culturally diverse society represents an enabling environment for innovativeness shall be discussed. Nevertheless, a number of evidences and empirical data which support the linkage between cultural diversity, immigration and the innovation process shall be analysed. Statistical reports have shown that at the turn of the century â€Å"4.6% of world population was born in a different country from the one where it currently lived†. (Bratti and Conti, 2012:2). Given the size of this phenomenon, immigration has come into sharp focus on the global agenda, currently being at the centre of many economic and political debates and its economic consequences giving rise to a high level of research activity. Thus, it would be of highly importance to consider the contribution of increasingly cultural diversity in many societies to the innovation system especially when dealing with economic analysis and policy. However, in order to be able to analyse the effects of immigration and cultural diversity on innovation, firstly, the meaning of „innovation† as a concept along with its indicators should be tackled. Defining â€Å"innovation† could be rather a difficult task as it is a â€Å"multi-faceted phenomenon†, and a widely used concept in various ways and different contexts. (Venturini, 2005: 1) However, it could be generally agreed that †Innovation is different from pure invention. Innovation involves the successful implementation of a new product, service or process, which for most activities entails their commercial success.† (Gordon and McCann, 2005: 3). In addition to this, Ozgen, Nijkamp and Poot (2013: 3) state that innovation is achieved â€Å"by means of analytical knowledge† and argue that â€Å"The improvement of an existing product or the modification of an existing process or organizational arrangement can also be viewed as an innovation.† Regarding the measures of innovation, the most prominent ones are the number of patent applications and the Total Factor Productivity, used as proxies of technological growth and effective innovation s at both firm and country levels. Having now defined this process, leads the analysis further, to establishing how does immigration affect innovation. In recent years, research activities have demonstrated a rather positive correlation between migration and innovativeness, as â€Å"individuals coming from different countries usually have different, complementary skills with respect to natives, and the production of new ideas may be positively influenced by contacts and interchanges between culturally diverse individuals† (Bratti and Conti, 2012: 4). In addition to this, â€Å"migration brings youth to ageing countries, and allows ideas to circulate in millions of mobile minds. That is good both for those who arrive with suitcases and dreams and for those who should welcome them†. (The Economist, 2011) A rather more technical research on this matter is conducted by Ozgen, Nijkamp and Poot (2012) who study the impact of size, skills and diversity of immigration on the innovativeness of host regions using the number of patent applications per million inhabitants from 170 regions in Europe for the periods 1991-1995 and 2001-2005. According to this study, there are five mechanisms through which immigration may boost innovation: â€Å"the population size effect†; â€Å"the population density effect†; â€Å"the migrant share effect†; â€Å"the skill composition effect† and â€Å"the migrant diversity effect†. (Ozgen, Nijkamp and Poot, 2011:2). The first three mechanisms result from the fact that immigration increases the local aggregate demand. This boost in the aggregate demand could be met through an increase in the level and diversity of local production, which in the long run might need additional investment and thereby will encourage product and process innovation. Furthermore, local economy prosperity not only will generate firm growth but will also encourage additional start-up firms resulting into an innovation lift. Moreover, usually attracted to the large metropolitan areas with better job opportunities, migrants increase the urban population and thereby strengthen the forces of agglomeration which leads to greater innovation. (Ozgen, Nijkamp and Poot, 2011: 3). A more debated way through which the innovation system is enhanced by immigration refers to the skill composition effect on innovation. Given that the modern economy is in a constant quest for fresh ideas and better goods that would accelerate business growth, the global competition for highly-skilled migrants has gained magnitude. â€Å"Their role in innovation may seem obvious: the more clever people there are the more ideas are likely to flourish, especially if they can be commercialised.† (The Economist, 2009) Considerable empirical evidence for this is provided by Kerr who gathered data about the 8 million scientists who had acquired an American patent between 1975 and 2004. Hence, he found that the share of patents given to American-born scientists fell while the share of all patents awarded to immigrant scientists from China and India increased from 4.1% in the late 1970s to 13.9% between 2000 and 2004. (The Economist, 2009) Moreover, Kerr and William Lincoln (2008) ana lysed the way changes in the number of H-1B visa admissions reflected on patents in the years between 1995 and 2006. It is imperious to mention that H-1B visa is the United States work visa for skilled immigrants, which allows US companies to employ foreign workers in specialty occupations that require theoretical or technical expertise as well as the attainment of a bachelor’s degree or its equivalent as a minimum. Thus, they point out that â€Å"the estimates suggest that a 10% growth in the H-1B worker population is associated with a 2% increase in patenting† (Kerr and Lincoln, 2008: 20) Bosetti, Cattaneo and Verdolini (2013: 1) predict that skilled immigration has a significant positive contribution not only to the knowledge creation in host countries as â€Å"they add to the pool of skills in destination markets†, but also enhances natives ‘productivity as the interaction of diverse cultures and approaches in problem solving and brain storming situations might give birth to new, original ideas. In order to support these predictions, they have studied the effect of skilled migrants on the number of patents applied for through the Patent Cooperation Treaty and citations of scientific publications, as proxies of innovation in a panel of twenty European countries from 1995 to 2008. Thus, in accordance with their initial prediction, Bosetti, Cattaneo and Verdolini (2013:11) found out that â€Å"the variable measuring the stock of knowledge in a given country (stock of RD expenditure) exerts a positive and statistically significant effect on innovation. A 1 percent increase in the stock of RD expenditures is associated with a 0.6 percent and a 0.4 percent increase in patent application and citation, respectively†. In a similar vein, Hunt and Gauthier-Loiselle (2009) measure the likeness of skilled immigrants to enrich innovation and at what extent. They do so by evaluating the differences in patenting behaviour between immigrants and natives as well as the state-level determinants of patenting using a panel of data from 1940-2000 in the Unites States. The results show that a 1% increase in the college graduate immigrants implied 6.1% rise in patents per capita while 1% increase in the share of college natives raise patents per capita only by 3.5%. Furthermore, â€Å"1.3 percentage point increase in the share of the population composed of immigrant college graduates and the 0.7 percentage point increase in the share of post-college immigrants both increased patenting per capita by about 12% (..). The 0.45 percentage point increase in immigrant scientists and engineers increased patenting per capita by about 13%.† (Hunt and Gauthier-Loiselle, 2009:20). Hence they discover that one way ski lled immigrants could boost patenting per capita is by engaging in science and engineering as the knowledge and skills these occupations request are more easily transferable across countries. Skilled immigrants could also enrich patenting per capita, if an immigration policy regarding immigrants’ selection according to their abilities and knowledge levels was introduced. This would attract more science and engineering orientated migrants and would encourage less skilled migrants to acquire higher education and engage themselves more into the innovation process. (Hunt and Gauthier-Loiselle, 2009: 2). Nevertheless, due to migration and globalisation, diversity has become an increasingly outstanding feature of today’s world. This brings into discussion the fifth mechanism through which immigration can boost the innovation system, the migrant diversity effect, as an important link to innovation. A say on this matter had the European Commission (2008: 8), in their work regarding the diversity journey in search for talent, competitiveness and innovation: â€Å"as innovation processes depend on harnessing creativity, and while dynamic as well as supportive systems of management can elicit the best from staff, like-minded people will usually produce like-minded results. Diversity in the workforce can, however, help companies to break this mould and the cycle of limited unilateral thinking and, in so doing, set them free to discover new products, markets, and ways of doing or leading business†. Empirical evidence that confirms the positive linkage between cultural diversity and innovation is provided by Niebuhr (2006). She investigates the impact of a cultural diverse labour force in German regions on innovation, using a sample of 200 different nationalities. The results show cultural diversity to be beneficial to innovation: â€Å"Due to their different cultural backgrounds, it is likely that migrants and native workers have fairly diverse abilities and knowledge. Thus, there might be skill complementarities between foreign workers and native in addition to those among workers of different qualification levels.† (Niebuhr, 2006: 564). But are cultural diversity and immigration always beneficial to innovation? According to Bratti and Conti (2012: 4), cultural diversity might also cause difficulties in communication, especially when natives and immigrants do not speak the same language. This might reduce social capital and therefore act as an impediment to innovation and economic performance. In addition, Ozgen (2013: 92) finds as outcomes of cultural diversity, lower levels of trust and higher discrimination within firms, â€Å"non-transferability of skills† or â€Å"non-recognition of qualifications† which play as impediments in ideas exchange or the formation of new knowledge. Similarly, â€Å"co-ethnic networks can lead to spatial or occupational segregation and clustering of migrant groups, which may also impede the contribution of immigrants to firm innovation†. Moreover, a few other situations which lie on the negative side of immigration could be observed. That would be the case of areas experiencing higher inflows of low-skilled or low educated migrants: â€Å"unskilled immigration can have a negative effect by reducing social capital, creating communication problems among workers or pushing firms to lower their efforts to introduce product and process innovations†. (Bratti and Conti, 2012:16). In order to uphold this statement, Bratti and Conti (2012: 22) evaluate the effect of low-skilled immigrants in Italian provinces on patent applications, as a proxy for innovativeness. Thus, they find evidence that there is a significant negative effect not only of low-skilled migrants, but also an overall negative effect of large inflows of immigrants on innovation: â€Å"rising immigrants’ share by 1 p.p. produces a 0.064 percent reduction in patents’ applications per 1,000 inhabitants.† This negative effect is proved to be mostly driven by the characteristics of immigrants who â€Å"mainly appear as a source of low-skilled and cheap labour force, which is employed in traditional economic sectors† (Bratti and Conti, 2012:11). Although it focuses especially on Italy, Bratti and Conti’s study is not necessarily a particular case, as their findings are also consistent with the Lewis’ work (2011: 1031) who has proved that areas rich in low-skilled immigrants areas adopted less machinery, giving technological change a slower evolution and: â€Å"plants added technology more slowly between 1988 and 1993 where immigration induced the ratio of high school dropouts to graduates to grow more quickly†. Hence, the substantial immigration boom from the end of the last century had a negative impact of knowledge formation and actively led to a slow growth in the supply of skills in the United States: â€Å"only after the large wave of immigration in the 1980s did high-immigration ci ties become more unskilled than low immigration cities.† (Lewis, 2011: 1031). On the other hand, there are also claims that even low-skill immigrants can indirectly enhance productivity gains and innovation: â€Å"Even low-skill immigrants who start small businesses that stay small are important to the American economy. They provide low cost services and access to more goods. There are also second-order effects, for example someone who provides child or elder care cheaply provide an invaluable service. This allows natives to works outside of their home† (The Economist, 2010). Similarly, Peri (2009: 17) has found a positive linkage between productivity gains and immigration in the United States in the years between 1960 and 2006, although the most majority of the immigrants in his sample were low-skilled and engaged in menial work. He proves that the inflow of unskilled migrants resulted in a more efficient allocation of skills and education to jobs amongst natives, thereby leading to an increase in the total factor productivity. Additionally, the negati ve effects of cultural diversity and unskilled immigrants could be overcome by properly exploiting the competencies of skilled immigrants as well as by attracting more highly educated immigrants. This could be achieved by introducing favourable immigration policies for high-skilled immigrants, in order to foster innovation and economic growth. Furthermore, free language courses and job-related training programs could be provided for immigrants in order to reduce language barriers and allow them to develop or upgrade their skills. To conclude, on theoretical grounds, there are several ways in which immigration and cultural diversity can affect both positively and negatively the innovation system. Given such a mixture of positive and negative effects, the overall impact of immigration on innovation should be considered in terms of empirical evidences. In this sense, this essay has presented a number of different studies and approaches from European countries, but also from the United States. What is more, five mechanisms through which immigration can boost innovation have been analysed. As opposed to this, several negative effects of cultural diversity and immigration with regards to the innovation process have been considered along with several ways these drawbacks could be overcome. Thus, all things considered, it could be consented that migration and cultural diversity represent an opportunity as much as a challenge, but if managed carefully it would lead to positive outcomes such as innovation, technologica l change, increasing productivity gains and ultimately to economic growth.

Pluripotent Stem Cells: Benefits, Properties and Uses Pluripotent Stem Cells: Benefits, Properties and Uses INTRODUCTION Pluripotent stem cells give rise to nearly all cells types of the body, like, muscle, nerve, heart, and blood. They hold huge promise for both research health care. The advance in human biology continues to generate interest among scientists, patients suffering from a wide range of diseases, including cancer, heart disease and diabetes, their families. Embryonic stem (ES) cells, is derived from inner cell mass of mammalian blastocysts they have the ability to grow for an indefinite period while maintaining pluripotency. These properties have led to hope that human Embryonic Stem cells might be useful to understand the disease mechanisms, to monitor effective and safe drugs, to treat patients of various diseases and injuries, such as juvenile diabetes and spinal cord injury. Cell culture is the one of the most important basic biomedical research. From many decades, many innumerable insights into both normal pathologic cellular processes have been gleaned by the study of human cells explanted in vitro. Primary human cells have a small life span in culture, there is a regulation of tissue formation, regeneration, and repair. Many human cell types have never closely been adapted for the expansion in vitro, and the lack of available models of normal pathologic tissue structure has render many new important questions in human growth and disease pathogenesis and it is hard to find. At present three types of methods have been reported to induce pluripotency artificially in mouse somatic cells. Embryonic stem like cells can also be recognized by long-term culture of bone marrow cells, and pluripotent stem cells can be generate adult germ cells, either by vitro culture of spermatogonial cells or by the parthenogenesis of unfertilized eggs. The capability to reprogram cells from the human blood will let the generation of patient-spec ific stem cells for the diseases. In this disease-causing somatic mutations are then restricted to the cells of the hematopoietic lineage. Depending on methods used, reprogramming of the adult cells to gain iPSCs may pose significant risk those could limit their use in humans. Many scientists around the world, announced the discovery of the method that could eliminate oncogenes after the induction of pluripotency, which will increase the potential use of iPSC in human disease. In April 2009, it was verified that generation of iPS cells is feasible without any genetic modification of the adult cell: a repetitive treatment of cells by means of certain proteins channelled into the cells viapoly-arginine anchorswas sufficient to induce pluripotency. Pluripotent stem cells are a unique scientific and medical source.The pluripotent stem cells are derived using non-Federal funds 8yat the beginning, embryos donated voluntarily by couples who are undergo fertility treatment in an vitro ferti lization clinic. Human embryonic stem cells isolated from more surplus embryos from in vitro fertilization clinics represent an immortal circulation of pluripotent cells that can theoretically generate any cell type inside the human body. PLURIPOTENT STEM CELLS PLURIPOTENT STEM CELLS are generated from adults cells where induced pluripotent stem cells is the part of pluripotent stem cells and it is also called as iPS cells or iPSC’s. Pluripotent stem cells give rise to nearly all of the cells types of body, like muscle, nerve, heart, and blood. Pluripotent stem cells are called master cells because they are able to make cells from all three body layers, so they can produce any cells or body needs to repair itself, it is called pluripotency. Pluripotent stem have promising future in the area of regenerative medicine because it it is different in effect on the cells of the body which are neurons, heart, pancreatic liver cells. It can help in the representation of single cell which can remain to lost the damage or diseased cells. IPSC they are similar to natural pluripotent stem cells, like embryonic stem cells in many ways, like the appearance of certain stem cell genes proteins,  chromatin methylation  patterns, doubling time,  embryoid body  formation,  teratoma  formation, viable  chimera  formation, and potency and differentiability. Pluripotent stem cells EMBRYONIC STEM CELLS Embryonic stem cells is the most important type of pluripotent cells. Embryonic stem cells(ES cells) arepluripotentstem cellsthat are derived from theinner cell massof ablastocyst an early-stage preimplantation  embryo. Humanembryos reach the  blastocyst  stage 4–5 days postfertilization, at which time they consist of 50–150 cells. From adult tissue iPSC has been derived. They cannot by pass the need of embryos but they can be matched in the patients which mean that pluripotent stem cells line will be present in the each individual. Without any risk of immune rejection autologous cells can be used for recognising the basic behaviour of disease present in the patients therapeutic transplants are not safe in iPSC technology. ESC that are appeared which have large domains of the genome that have a specific histone code, that are not found in more mature cells, which allows very fast inactivation or activation of gene expression. Embryonic stem cells arepluripotent th at are able todifferentiatein all derivatives of the three germ layers:ectoderm, endoderm, andmesoderm. It includes more than 220 cell types in the adult  body. Pluripotency distinguishes embryonic stem cells from  adult stem cells  found in  adults; while embryonic stem cells can produce all cell types in body, adult stem cells they are multipotent  and they can create only limited number of cell type. Human embryonic stem cell structure SOMATIC CELL NUCLEAR TRANSFER The somatic cell nuclear transfer (SCNT) means, transferring the nucleus from a somatic cell, any cell of the body, to an other cell, in this case it’s an egg cell. This kind of pluripotent stem cell called ntES cell, which has only been made successfully in the inferior animals. To make ntES cells in the human patients, an egg donor, would be needed. The process of transferring a differentnucleusinto the egg â€Å"reprograms† it to a pluripotent condition, reactivating full set of genes for creating all the tissues of the body. PRODUCTION OF INDUCED PLURIPOTENT STEM CELLS iPSCs are introduced in a set of pluripotency associated genes or reprogramming factors in to a given cell kind. The original set of reprogramming factor are genes Oct4 (Pou5f1), Sox2, cMyc, and Klf4. It is a slow and unsufficient process which takes 1-2 weeks in mouse cells 3-4 weeks in human. It has efficiency of 0.01%- 0.1%. For improving the efficiency and time taken to get ipsc considerable changes have been done. In reprogramming factor, cell start to make colonies that look like pluripotent stem cells. Pluripotency is maintained by a combination of epigenetic, transcriptional and posttranscriptional mechanisms. PRODUCTION OF Ipsc CELLS GENERATION OF INDUCED PLURIPOTENT STEM cells. They divide culture donor cells. Transfect the stem cell-associated genes into cells by viral vectors. Harvest and culture the cells according to the Embryoic Stem cell culture by the use of mitotically in feeder cells. A small set of transfected cells become iPS cells generate ES-like colonies Generation of IPS cells Types of Pluripotent Stem Cells There are several types of pluripotent stem cells are Embryonic stem cells which are joined from the inner cell mass of blastocyst the embryos are produced from in vitro fertilisation, although this is important cause it eliminates the embryo, which could have been implanted for the formation of a baby. Embryonic germ cells which are obtained from the aborted foetuses and these pluripotent cells are copied from past cells. These past cells are those which can form sperm eggs. Embryonic carcinoma or the cancer cells which are cosset from tumour that sometimes are prevalent in a a foetus. DIFFERENCE BETWEEN TOTIPOTENT,   PLURIPOTENT, AND MULTIPOTENT Totipotent cells can form all the kind of cell in a body, in addition the extraembryonic, or the placental cells. Embryonic cells, the 1st couple of cell divisions following fertilization are the only cells that are totipotent cells. Pluripotent cells can also give rise to all of the type of cells that make up the body. Embryonic stem cells are called pluripotent. Multipotent cells can expand into more than 1 cell type, but they are more limited than the pluripotent cells, adult stem cells cord blood stem cells are often considered as multipotent. BENEFITS OF PLURIPOTENT STEM CELLS Pluripotent stem cells give a renewable basis of healthy cells tissues to treat many type of diseases similar to heart disease and diabetes. People who are burn those patients who suffer from autoimmune diseases like Parkinsons can give advantage from the usage of pluripotent stem cells. Pluripotent stem cells have large potential for treatment of diseases, because they give rise to majority of cell types in human body,which include muscle, blood, heart nerve cells. The use for pluripotent stem cells include the generation of cells tissues that are use in transplantation. Drug study research next method that pluripotent stem cells are beneficial. Animals are mostly used to measure the safety and use of drugs. Those drugs which are secure and used in development for testing on animals. TURNING PLURIPOTENT CELL INTO TREATMENT Over time, many techniques are developed, pluripotent stem cells could any one of the day allow doctors to create form, rejection-proof transplant to patch a scarred heart, revitalize damaged nerves or reboot an immune system which is not able of fighting infection. Doctors have first obtained  pluripotent  stem cells that match the patient genetically through genetic  reprogramming,  nuclear transfer, or parthenogenesis. There are four critical steps: To grow  pluripotent  stem cells that create a large quantity of healthy cells. Restore faulty genes,this would be needed if the cells are carrying a genetic disorder, such as sickle cell anemia which turn the stem cells into a specific cell kind or a tissue.A genetically healthy line of  pluripotent  cells is recognized, they must be creating specialized kinds of cells and this process is called as differentiation. To transplant cells or tissue to the diseased or damaged organ or tissue,the cells will require to reach right part of the body, take hold and start to function. Scientists know how to deliver blood to the stem cells, but they still need to develop some effective delivery method for other cell types. Getting the pluripotent stem cell The cells can be made in one of several ways: Nuclear transfer— By using a patient’s skin cell and then transferring it into an egg (possibly the patient’s own, or of an egg donor). Genetic  reprogramming— By transforming a skin cell or blood cell or other cell from the patient to a  pluripotent  stem cell. Parthenogenesis— This is done by using unfertilized eggs. A woman may be able to give her own eggs to make stem cells that match her genetically, or draw on master banks of stem cells which are made from eggs. WHY ARE PLURIPOTENT STEM CELLS IMPORTANT? Pluripotent stem cells can be used to produce any cell or tissue the body might need to challenge a wide range of diseases, from diabetes to spinal cord injury, to childhood leukemia,or to heart disease. Pluripotent  stem cells can potentially be modified to provide a perfect genetic match for any patient. It means that the patient could get transplants of tissue and cells without matching tissue and tissue rejection problems. There is also no need to take powerful immune-suppressing drugs for the rest of their lives. Although there is time in achieving this, researchers have treated mouse models of human disease by using this strategy and hope that same can be done with human patients. Disease in a dish: Pluripotent stem cells create excellent laboratory models for studying how a disease unfolds, which further helps scientists to locate and track, very earliest disease-causing actions in cells. Immune deficiencies like type1 diabetes, muscular dystrophy, and myriad other disorders which are embedded in fetal development. In the lab, researchers monitor from where the first muscle cell comes from, or the first blood cell, and how this is different when the patient has a genetic disease. By the use of this information, doctors are able to correct the genetic defect before the disease advances. Applications: Pluripotent  stem cell has different characteristics that make it useful in different ways : Induced pluripotent cells(iPS cells) offer a unique chance to model many human disease and are already being used to make a lot of new discoveries about premature aging, disease,cancer, and more. They are made from a person’s own cells, they can be potentially manipulated to fix the defects that are causing disease and then used to create healthy cells for transplant that won’t be rejected by the immune system. Embryonic stem cells(ES cells) are standard for the biological theory of pluripotency. Scientists are continuosly working with Embryonic Stem cells to study more about a cell with pluripotency and discover safe better ways to create iPS cells. Each type of ES cell is important for different reasons: ES cells made from donating early embryos are unique tools for the understanding of earliest stages of human development specific tissues form, because they’re not modified to individual patients, their value is mainly in research. MEDICAL RESEARCH Disease modeling and drug development An attractive feature of the human iPS cells is their ability to derive them from adult patients for the study of cellular basis of human diseases. Since iPS cells have property of self-renewing and are pluripotent, they stand for a theoretically unlimited source of patient-derived cells which further can be turned into any kind of cell in the body. This is important because many other types of human cells which are derived from patients tend to stop rising after a few passages in laboratory culture. iPS have been generated for a broad variety of human genetic diseases, including common disorders such as Down syndrome and polycystic kidney disease. Organ synthesis A proof-of-concept by induced pluripotent stem cells (iPSCs) to make human organ for the transplantation  was reported by researchers of Japan. Human ‘liver  buds’ (iPSC-LBs) were grown from a mixture of three different types of stem cells: Hepatocytes  (for liver function) coaxed from iPSCs Endothelial stem cells  (to form lining of  blood vessels) from  umbilical cord blood Mesenchymal stem cells  (to form  connective tissue). This new approach allows different cell types to self-organize into complex organ, mimicking the process in  fetal development. After growing in vitro for few days, the liver buds were transplanted into mice where the ‘liver’ quickly connected with host blood vessels and then continued to grow. Tissue repair Embryonic cord-blood cells were induced to pluripotent stem cells by the use of plasmid DNA. Using cell surface endothelial/pericytic markers  CD31  and  CD146, researchers have identified vascular progenitor, which is high-quality, multipotent vascular stem cells. After the iPS cells were directly injected into the  vitreous  of damaged  retina  of mice, the stem cells then engrafted into retina, grow repaired the  vascular vessels. Red blood cells In 2014,  type O  red blood cells  were synthesized at Scottish National Blood Transfusion Service from iPSC. The cells were induced to become a  mesoderm   then  blood cells   then red blood cells. The final step was making them eject their nuclei mature properly. Type O rbc’s can be transfused into all patients. Each pint of the blood contain about 2 trillion red blood cells, although some 107 million blood donations are collected globally each year. Human transfusions were not expected to begin until 2016.
