Military Revolutions and Revolution - 1342 Words
Military revolution and revolution of military affair The world is continuing to experience changes that are affecting every generation of people in society without regard to race, religion, age, sex, political status or geographical location. These changes are certainly important chapters for our history books. For the most part I would say these changes are like evolution which has led to the diversification of all living organisms from a common ancestor, known as a scientific development discovered by the scientist Charles Darwin. Comparatively changes that occur in society affecting organizations, people, politics and policies and technology results in diversification in ways of life over time as result of what we call aâ⬠¦show more contentâ⬠¦In other words the author is saying political debates, strategies and polices are develop from the outcome of military revolution which is instrumental in bring about the technological development in weaponry that are developed as a result of RMA. Although it is widely recognized that technological changes are the revolutionizing force for warfare in the 21st century the issues that are addressed in Military Revolution are synergic to those of RMA. The[1]â⬠Anatomy of a Failed Occupation of 1871â⬠is a prime example of why these two revolutions cannot operate effectively separately despite there are significant differences. This was a time of great uprising in southern United States when local terrorist was able to undermine the state government to reestablish their own political dominance. The government failed miserable; due to poor planning inappropriate and infective resources, such as advance technology. In addition the Army lack will power needed to establish and enforced the political policies and strategies of the government. Reviewing of several literatures reveals the great promises revolution in military affairs holds for conventional, combined-arms warfare, but the same cannot be said of i ts potential value in conflict short of war.

Immigration Racism and Greece Free Essays
Introduction Nowadays, it has been observed in several countries that immigrant students do not have an equivalent school performance with their native classmates (Pisa, 2003). This essay is concerning the different school performance of the immigrant and Pontic Greeks students in Greece. The first section of this essay is about the immigration to Greece, and it explores the reasons of the increasing immigration to Greece, the second explores the attitudes of Greeks towards immigration, whereas the next section highlights the racism and xenophobia in Greeceââ¬â¢s society. We will write a custom essay sample on Immigration: Racism and Greece or any similar topic only for you Order Now Section four is about the ethnocentric school curriculum in this country, whereas, the next section is about, the differnces of the socioeconomic status and cultural capital towards these two groups of immigrants. Finally, the next two sections are about the intercultural education in Greece and its problems. Immigration to Greece Before we go into the procedure of analysis of our topic it is obvious that we should explore the fact of immigration to Greece. The first decades after World War II, a lot of Greeks left their country and they immigrated in many countries such as USA, Canada, Germany and Australia which were more economically developed, because the rates of unemployment and poverty in Greece were extremely high (Katsikas ump; Politou, 2005), however, Greece nowadays has become a country where many immigrants from different countries arrive, hoping that Greece will offer them the opportunities to have a better life (Triantafyllidoy ump; Veikou, 2002). The Mediterranean countries have become a magnet for many immigrants replacing the traditional immigration countries like Germany and France (Brenner ump; Fertig, 2006). Moreover, immigrants in Greece exceeds the needs of the Greek industry, and Greece has the highest proportion of immigrants between the European Union countries (Siar, 2008). Greece has become the centre of immigration since 1980, when many Greeks who have immigrated to other countries returned back, morever, in 1985 many repatriated Greeks returned back from the U. S. S. R and Albania, finally, the last two decades many economic immigrants from many developing countries from the Eastern Europe, Asia, and Africa came to Greece (Katsikas ump; Politou, 2005). A research which was conducted by Eurostat in 2006 has shown that in Greece there are 884. 000 immigrants and the majority of them came from Albania, the 62% of immigrants in Greece are Albanians (Siar, 2008). However, there are a lot of people from many countries such as Pakistan, India, Georgia, Ukraine, Romania, Bangladesh, Afghanistan and Egypt (Siar, 2008). Moreover, the last decades a lot of ethnic Greeks returned to Greece such as Pontic Greeks and Greek Albanians and also there are a lot Greek citizens who returned to Greece from countries such as Cyprus and Turkey (Fakiolas ump; King, 1996). Furthermore, we should mention that many irregular immigrants especially from Asian countries, live in Greece, and their number becomes every year more and more increased, this happens because they try to enter to Greece through Aegean sea, which is very difficult to be controlled, due to the fact that there is a line of seashore which is 18,400 km and a vast amount of islands which are near to Turkish coasts, thus, it is quite easy from them to enter to Greece (Siar, 2008). In addition, nowadays, in Greece, there is an increasing number of asylum seekers, who try to enter to the most industrialised European countries, the majority of them comes from countries like Iraq, Pakistan, and Afganistan, unfortunately, Greek state, does not usually recognize them, and only few applications get a positive response (Siar, 2008). Moreover, it is quite useful to explore the reasons that Greece attracts many immigrants. First of all, the majority of European countries have stricter immigration policy than Greece, as a result, a lot of people immigrate to Greece (Leghari, 2009). As we have mentioned before, Greece has many islands and a vast coastline, moreover, it has a lot of mountains, it is obvious that Greeceââ¬â¢s borders are very difficult to be secured, as a consequence, many irregular immigrants enter the country (Leghari, 2009). Greece, is situated, between the developed and developing countries, as a result, many people from the developing countries immigrate to Greece because their countries very usually face a lot of conflicts and changes (Leghari, 2009). The fall of Communism in many countries made people to leave their countries, the immigration of Pontic Greeks, it was a result of the fall of Communism in U. S. S. R (Triantafyllidoy ump; Veikou, 2002). Another important reason which promotes immigration to Greece is the fact that the last decades there was an economic development (Leghari, 2009). Moreover, there was a decline in Greeceââ¬â¢s population and as a result, there was a need of labour force (Leghari, 2009). In addition, we should mention that there is a lack of workers in the construction sector because Greeks do not want to do these kind of jobs (Leghari, 2009). As a result, the majority of immigrants in Greece do these kind of jobs, according to, the Greek Ministry of Interior the 32% of immigrants work in the construction sector (Siar, 2008). Finally, the fact that Greeceââ¬â¢s economy, is characterized by an informal sector gives the opportunity to many irregular immigrants to work in this sector (Leghari, 2009). It is obvious that all of these reasons promote immigration, however, it will be quite useful to explore the attitude of public opinion and Greek policy towards immigrants in Greece, because this, will help us, to shed light on the differences in school performance between Pontic Greeks and immigrant students, the next section of this research is about the attitude of Greek policy and public opinion towards immigrants. Attitude of Greek Policy and Public Opinion Towards Immigrants First of all, we should mention that although, in Greece there are a lot of immigrants there is no any effective immigration policy (Triantafyllidoy ump; Veikou, 2002). The first decades of immigration to Greece, it was quite obvious that there was no such policy because there were no indications of the extent of this phenomenon, however, until now, there are not effective policies, as a result, we are able to assume that maybe Greek politicians and also society, believe that mass immigration will have an effect on Greekââ¬â¢s homogeneity (Triantafyllidoy ump; Veikou, 2002). On the other hand, any migratory policies applied in Greece favors some specific groups, such as Pontic Greeks, moreover, Greek citizenship was granted to them when they arrived in Greece (Triantafyllidoy ump; Veikou, 2002). This happens because Greece is one of the most homogenized societies (Rozakis, 1997), and Greeceââ¬â¢s homogeneity comes from the fact that Greeks national identity is based on Greeceââ¬â¢s glorious history and orthodox religion (Triantafyllidoy ump; Veikou, 2002). In line with, Triantafyllidou and Veikou: Greek national identity includes both ethnic and civic features, which are dynamically organized and interact with the changing international context and internal needs of the societyâ⬠(Triantafyllidoy ump; Veikou, 2002: 195). However, nowadays, there are a lot ot social changes in Greece due to the fact of mass immigration, as a result, there is a need Greeceââ¬â¢s national identity to be reconsidered and redefined to meet the demands of global and national changes (Triantafyllidoy ump; Veikou, 2002). It is obvious, that this fact led Greeks to believe that immigrants will elimintate their national identity and as a result, they do not have a positive attitude towards immigration. On the other hand, Greeks have a positive attitude towards Pontic Greeks, and they have a better treatment than immigrants from other countries such as Albania, we are able to assume that Pontic Greeks were a privileged group of immigrants, moreover, this positive attitude towards Pontic Greeks is based on media which have a more positive attitude to them than to other immigrants (Voutira, 2004). This happens because Greeks believe that Pontic Greeks are Greeks with some common habits and they have the same religion as a result, they believe that Pontic Greeks have, like them, national consciousness, however, they do not examine the fact that some of them do not even speak the Greek (Triantafyllidoy ump; Veikou, 2002). One of the most important factors of the construction of Greeks national consciousness was the fact that many Orthodox Greeks lived in some other places which some centuries ago were under the control of Greece and made Greeks believe that these lands should be one day controlled by Greece again, helping Greeks Orthodoxs to be integrated with their homeland, this is, what is called in Greece ââ¬ËGreat Ideaââ¬â¢(Triantafyllidoy ump; Veikou, 2002). It is obvious, that these reasons, guide Greeks to have positive attitudes towards Pontic Greeks. We are able to assume that a better reception is granted to Pontic Greeks when they come to Greece, and their acceptance in Greek society is secured, due to their ââ¬ËGreeknessââ¬â¢(Triantafyllidoy ump; Veikou, 2002), as a result, it is obvious that their Greek roots make it easier to be integrated in Greek society, this better integration of Pontic Greek renders us capable of understanding that Pontic Greek students have more chances to have a better school performance than the other immigrant students. However, their Greek roots, it is not the only reason which give them the opportunity to have a better school performance, the next section, explores another reason, which promotes their better educational attainment, this reason is the fact that Greeceââ¬â¢s society is characterized by xenophobic and racist beliefs. Xenophobia and Racism in Greece Immigration helps the receiving countries to develop their economies, however, sometimes in many countries there are negative attitudes against immigrants (Card, Dustmann, ump; Preston, 2005). In Greece, a research which was conducted by Anna Triantafullidou and Andoni Mikraki has shown that Greeks since 1995 have not xenophobic attitudes against immigrants, moreover, the 31% of Greeceââ¬â¢s population believed that immigrantââ¬â¢s rights should be more extended and only the 4% of the total population had negative attitudes against immigrants (Triantafyllidou ump; Mikrakis, 1995). However, the high rates of immigration this decade, has triggered the xenophobic and sometimes racist attitudes in Greek society, people nowadays in Greece believe that immigrants increase the rates of unemployment and criminality and very often these stereotypes are guided by the media, moreover as we have mentioned before, Greek society is a homogenized society and Greeks believe that the mass immigration will have an effect on Greeceââ¬â¢s homogeneity (Hatziprokopiou, 2005). On the other hand, it is quite difficult, to give an explanation, to the growth of xenophobia and racism in this country, however, these attitudes become more and more frequent, this is clear, if we consider the institutional racism which is very usual, in the police stations, the maiority of policemen in Greece tend to believe that immigrants are criminals (Hatziprokopiou, 2005). Moreover, racist attitudes, are a daily phenomenon, even in Greek TV series, there are racist attitudes, for instance, they show immigrants in some ways, such as, criminals, prostitutes, or domestic servants, with this way, there is a reproduction of stereotypes and xenophobia (Hatziprokopiou, 2005). However, these attitudes are very usual, in global history, because when there are a lot of social problems in a society, people try to find a weak social group to blame for these problems (Fenton, 1984), and Greece nowadays has a lot of roblems, due to the social changes due to immigration (Triantafyllidoy ump; Veikou, 2002), and the economic recession. As a result, there is a growth of racist and xenophobic attitudes. Moreover, these racist beliefs are very common in Greek schools, very often Greek students have negative attitudes towards immigrant students, their perception often is guided by their classmateââ¬â¢s country of origin, some specific immigrant groups especially Albania ns are faced xenophobic attitudes and stereotypes even in classrooms (Dimakos ump; Tasiopoulou, 2010). Of course, we cannot characterize Greek society, as a racist society, because it has been observed, that when there is a contact between Greeks and immigrants, there is a development of interpersonal relationships, and friendships, it is obvious that, that media, social problems and Greeceââ¬â¢s immigrations policy promote the racist attitudes towards immigrants (Hatziprokopiou, 2005). It is obvious, that the reproduction of the racist beliefs and stereotypes have an effect on school performance. As we have mentioned before, a better reception is granted to Pontic Greeks due to their ââ¬ËGreeknessââ¬â¢(Triantafyllidoy ump; Veikou, 2002), as a result, Pontic Greeks students do not have to face racist stereotypes in education, this issue, help us to understand that they have more chances to have a better school performance than the other immigrant students. Of course, Greeceââ¬â¢s homogeneity and racist attitudes towards immigrants, are not the only reasons which have an effect on school performance, the next section is about another important reason which guides the differences in school performance, this is the school curriculum.

Precision Worldwide free essay sample
Precision Worldwide, Inc. Recommendations: Precision Worldwide, Inc. (PWI) should cease production of their steel rings, proceed towards production of the new plastic rings, and scrap any unused or unsold steel inventories in conjunction with the availability of the new plastic ring product. The sooner the company is able to sell plastic rings, the sooner they will be able to realize the increased profit margins associated with that product. The introduction of the plastic ring from one of PWIââ¬â¢s competitors changes the dynamic of the market for this type of product as any end users of these rings will immediately see the merit of purchasing that said rings in plastic instead of steel. Any delays in making the plastic rings available could jeopardize PWIââ¬â¢s business relationship with buyers of the major assemblies that are also produced by PWI. The risk of losing buyers of major assemblies is too great to justify prolonged sales of the inferior steel rings once the plastic product is available. We will write a custom essay sample on Precision Worldwide or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page PWI should make every effort to reduce waste when disposing of raw steel inventory and finished goods. To facilitate this process, PWI may implement a 15% price reduction on steel rings until the beginning of September which will provide for increased sales for 14 weeks. The company will not make use of 70% wages during this time period due to the fact that the company will not be producing additional steel rings between May and September 2004. The projected loss to the company if remaining steel inventory is liquidated and scrapped-out at $0. 00 is approximately $278,192. 0 (see below). Total cost of Steel Inventories| $390,000. 00 | Cost of Raw Steel| $110,900. 00 | Cost of Steel Finished Goods| $279,010. 00 | | | Inventory projected on-hand by Mid-September| | (=15,100 rings/100*1,107. 9)| $167,292. 90| | | Total Scrap forecast| | (=Raw Steel Cost + Mid-Sep inventory projections)| $278,192. 90 | The above values give no credit to additional sales that may be projected as a result of discounting the steel rings. Once the plastic product is available in September, the company will discontinue availability of steel entirely. The chart below takes into account a comparison between 14 weeks of projected sales at a discount of 15% and assuming sales increase by 15% during that period as well as normal sales during the same period on steel rings. We are projecting a possible increase in sales of 15% to correlate with the discounting of steel product. 14 Weeks of Sales| Normal Pricing| Discount of 15%| | à | à | 690 units per week| $9,315. 00| $7,818. 00| 794 units per week| N/A| $9,111. 15| Based on current sales of steel, the company makes profits of approximately $86,865. 8 on an annual basis. The annual sales for plastic rings will be approximately $384,041, assuming the sales rate of plastic rings is comparable to the sales rate of steel rings (Chart 1). If the loss of $278,192. 90 is expensed at the end of year of sales of $384,041, the resulting net profit will be $105,848. 68 which is more than 22% higher net profit than the company can realize in a full year of normal steel sales (Chart 2). Calcu lations: Incremental Analysis Chart 1: Incremental Analysis| | Steel Rings| Plastic Rings| Incremental| | Selling Price| 1,350. 00| 1,350. 00| = 0| Incremental Revenue| Cost| 1,107. 90| 279. 65| = 828. 25| Incremental Cost| Profit| 242. 10| 1,070. 35| = 828. 25| Incremental Profit| Manufacturing Analysis Chart 2: Units| Steel Rings| Plastic Rings| | 6. 9 Per week| 1,670. 49| 7,385. 42| | 52 weeks| 86,865. 48| 384,041. 58| | Minus Sunk Costs (scrap)| | -278,192. 90| | Profit| 86,865. 48| 105,848. 68| | Increase in Profit| | | 18,983. 20| Table A-1 compares the cost of plastic and steel rings per 100. The table excludes the overhead cost that is allocated to administrative costs, which is a non-manufacturing cost that isnââ¬â¢t easily traceable to the production of rings. Same as above, manufacturing overhead cost is 80% of direct labor that results in a reduction to $52. 40 ($65. 50*. 8) for plastic and $157. 20 ($196. 50*. 80) for steel. Table A-1 Plastic Rings vs. Steel Rings Per 100| | | | Plastic Rings| Unit Cost| Steel Rings| Unit Cost| Material| $ 17. 65| à | $321. 90| | Direct labor| 65. 50| | 196. 50| | Overheada| | | | | Departmental| $52. 40| à | $157. 20| | Total (cost)| $135. 55| $1. 6| $675. 60| $6. 76| Assuming that the company doesnââ¬â¢t produce any more steel rings, Table A-2 uses cost supplied by the case study and illustrates that the raw material being a sunk cost, administrative cost removed and manufacturing overhead reduced. Table A-2 | For 100 Steel Rings| Unit Cost| Material (sunk)| $(321. 90)| | Direct labor| $196. 50 | | Overheada| | | Departm ental| $157. 20 | | Total Cost- Sunk Cost| $353. 70 | $3. 54 | Conclusions: When presented with the above information, PWI has little choice but to abandon current steel production, liquidate current inventories as quickly s possible and begin the production and sale of plastic rings. This will result in a loss to the company of approximately $110,990 in raw material and approximately $167,292. 90 in finished goods totaling approximately $278,282. 90. This loss is acceptable due to the fact that sunk costs should not be taken into consideration when making future business decisions, this course of action will ensure the least amount of risk to the companyââ¬â¢s reputation, and this loss can be recouped in approximately 37 weeks (278,292. 0 divided by 1,070 divided by 6. 9) at current rates of sale. Furthermore, the loss of scrapping steel inventories is a one-time event; subsequent yearsââ¬â¢ sales will be far higher than previous yearsââ¬â¢ sales due to increased margins i n plastic rings, thus further justifying this course of action. Assumptions: * Current steel inventories are valued at $390,000 which is inclusive of both raw material and finished goods. Of the $390,000, $110,990 is in raw material and $279,110 is in finished goods. From the date of the decision (May 31, 2004) until production of plastic rings is on-line (September 1, 2004) there are approximately 14 weeks of production and sales opportunity. * A 15% reduction in the price of steel rings will result in a 15% increase in sales providing for weekly sales of 794 rings per week (690 x 1. 15) for 14 weeks totaling 11,116 rings. * At the end of May, the company has approximately 25,000 steel rings on-hand (69014+15,100). * Assumes continued labor costs to produce the plastic rings, thus avoiding the reduction of 70% of regular wages. There is a risk to the company in converting all rings to plastic where only 10% of customers are currently demanding plastic rings. * There is a risk of less demand for plastic rings due to 4 times the wear of steel. * It is important to introduce plastic rings to the market because the competition is offering plastic rings at a lower cost. As an example, other companies are offering low-priced and low-quality machines resulting in increased future competition. * There will be a cost of $7,500. 00 for tools and equipment to manufacture the plastic rings, which will be taken as a depreciate expense o ver time.

Data Gathering Procedure Introd ucing inferential and descriptive statistics was aimed at delivering techniques for digital data gathering. The author of the dissertation provides detailed analysis of all gathering procedures. Plans for IRB and Summary The summary covers the basic points of methodology, but there is no mentioning about the IRB and their intentions. Research Tools In the dissertation, the scholar combines methodology and data analysis section into one chapter and, therefore, chapter 4 is dedicated to results and research tools used for the research. Nevertheless, data collection section is still represented along with descriptive statistic results, and regression analysis. Pilot Study Instead of introducing research questions and hypotheses, student introduces the analysis of research tools and pilot studies. The latter defines numerical data based on the results from electronic questionnaire. In whole, the scholar failed to follow the structure of a quantitative dissertation because data collectio n procedures have been considered in various chapters. Date Collection In whole, the scholar failed to follow the structure of a quantitative dissertation because data collection procedures have been considered in various chapters. Therefore, all information about the collection process should be represented in one section. Descriptive Statistics The section presents objective information about participants, as well as methods used to process numerical data. The student has included data about age, demographics, and disciplines in which learners are involved to define the relationships. However, no connection has been made with the research hypothesis.Advertising Looking for essay on education? Let's see if we can help you! Get your first paper with 15% OFF Learn More Reliability of the Scales The researcher discusses the connection between independent and dependent variables to prove the reliability of the sales chosen for data analysis. Therefore, this section could be approved. Population analysis and statistics, along with population mean analysis has been presented. The section focuses on quantitative data evaluation, which corresponds to the initial hypothesis. Each statistic finding has been analyzed from the viewpoint of the initial research questions. Discussion of the Study Discussion restates the research questions and defines relevance of statistics to the findings of the studies. At this point, discussion section should not have provided analysis and review of research questions. Rather, the focus should have been made on the actual interpretation of results. Interpretation of Findings Enumeration of research tools and design is inappropriate for this action. Instead, student should have discussed the implications and meaning of the obtained results either to approve to reject the research hypothesis. Reliance on theories is also irrelevant because previous discussions have already highlighted the theoretical frameworks. Implications The author focuses on practical applications of the research findings and accurately outlines various fields of future scientific explorations in the field. This is of particular concern to such aspects as social change. In addition, the research is beneficial for other scholars to develop new paradigms in learning. Recommendations for Action Due to a bulk of practical implications, the research can also be used for developing helpful recommendations for school instructors and administration.

Expansion of The Transcontinental Railroad and Western Culture essays
Expansion of The Transcontinental Railroad and Western Culture essays The story of the Lakota and the Great Plains is one of resilience and strength. Their story includes great moments of coming to together as a tribe and resilience against the westerners when the railroads were commissioned. The plains were home to the Lakota long before the settlers arrived, being said, there was no hesitation when came to protecting their home lands. Lakota Sioux, are the iconic warrior horsemen of the Northern Plains. Nevertheless, they did not always own such a powerful title. The Story of the Oyate meaning, The People, began deep inside the Wind Caves located in the Black Hills, South Dakota. According to The Oyate, they emerged from these Wind Caves, being fooled by a trickster who turned its self into a buffalo. One of the most significant spiritual figures in the Lakota culture along with the horse are the buffalo. The buffalo brings life to the people of the Great Plains, supplying trade, food, tools and hide for their homes. Thriving on the dense herds of buffalo the Lakota were able to have prosperous communities with a functioning government and religion. Despite the negative assumptions and claims by Europeans, the Oyate were well organized and grew into a well diverse, functioning community. Due to the mobility of their main source of life, it allowed the Lakota to move camp often. As a result of the vast numbers of buffalo, the Lakota became buffalo-hunting, nomadic horsemen. With the horse for transportation and vast herds of buffalo, the Lakotas prospered and their numbers grew until, by the nineteenth century, they outnumbered all other bands of the Great Sioux Nation combined. The Great Sioux Nation consisted of the Lakota, Dakota and Nakota, along with seven sub-tribal units. Another spiritual belief assisting in the tight nit community the Lakota displayed is the circle. The circle like the buffalo and horse is held in high esteem. According to the Oyate everything in life is a circle. Ev...

Science Projects for Every Subject
Science Projects for Every Subject How many times have you seen a science demonstration or watched a cool video and wished you could do something similar? While having a science lab certainly expands the type of projects you can do, there are many entertaining and fascinating projects you can do using everyday materials found in your own home or classroom. The projects listed here are grouped according to subject, so no matter what youre interested in, youll find an exciting activity. Youll find projects for every age and skill level, generally intended for the home or a basic school lab. To understand the basics of chemical reactions, start with the classic baking soda volcano or get a little more advanced and make your own hydrogen gas. Next,à learn the basics of crystallography with our collection of crystal-related experiments.à For younger students, our bubble-related experiments are simple, safe, and lots of fun. But if youre looking to turn up the heat, explore our collection of fire and smoke experiments.à Because everyone knows science is more fun when you can eat it, try some of our chemistry experiments involving food. And finally, ourà weather-related experimentsà are perfect for amateur meteorologists anyà time of the year.à Turn a Science Project Into a Science Experiment While science projects may be done simply because they are fun and raise interest in a subject, you can use them as the basis for experiments. An experiment is a part of the scientific method. The scientific method, in turn, is a step-by-step process used to ask and answer questions about the natural world. To apply the scientific method, follow these steps: Make observations: Whether youre aware of it or not, you always know something about a subject before you perform a project or experiment with it. Sometimes observations take the form of background research. Sometimes they are qualities of a subject you notice. Its a good idea to keep a notebook to record your experiences before a project. Make notes of anything of interest to you.Propose a hypothesis: Think of a hypothesis in the form of cause and effect. If you take an action, what do you think the effect will be? For the projects in this list, think what might happen if you change the amounts of ingredients or substitute one material for another.Design and perform an experiment: An experiment is a way to test a hypothesis. Example: Do all brands of paper towels pick up the same amount of water? An experiment might be to measure the amount of liquid picked up by different paper towels and see if its the same.Accept or reject the hypothesis: If your hypothesis was that all brands of paper towels are equal, yet your data indicates they picked up different volumes of water, you would reject the hypothesis. Rejecting a hypothesis doesnt mean the science was bad. On the contrary, you can tell more from a rejected hypothesis than an accepted one. Propose a new hypothesis: If you rejected your hypothesis, you can form a new one to test. In other cases, your initial experiment might raise other questions to explore. A Note About Lab Safety Whether you conduct projects in your kitchen or a formal laboratory, keep safety first and foremost in your mind. Always read the instructions and warning labels on chemicals, even common kitchen and cleaning products. In particular, note whether there are restrictions about which chemicals can be stored together and what hazards are associated with the ingredients. Note whether or not a product is toxic or poses a hazard if it is inhaled, ingested, or touches skin.Prepare for an accident before one happens. Know the location of the fire extinguisher and how to use it. Know what to do if you break glassware, accidentally injure yourself, or spill a chemical.Dress appropriately for science. Some projects in this list require no special protective gear. Others are best performed with safety googles, gloves, a lab coat (or old shirt), long pants, and covered shoes.Dont eat or drink around your projects. Many science projects involve materials you dont want to ingest. Also, if youre snacking, youre distracted. Keep your focus on your project.Dont play mad scientist. Young children may think chemistr y is about mixing together chemicals and seeing what happens or that biology involves testing the reactions of animals to different situations. This is not science. Good science is like good cooking. Start by following a protocol to the letter. Once you understand the basic principles, you can expand your experiment in new directions following the principles of the scientific method. A Final Word About Science Projects From each project, youll find links to explore many other science activities. Use these projects as a starting point to ignite interest in science and learn more about a subject. But, dont feel like you need written instructions to continue your exploration of science! You can apply the scientific method to ask and answer any question or explore solutions to any problem. When faced with a question, ask yourself if you can predict an answer and test whether or not it is valid. When you have a problem, use science to logically explore the cause and effect of any action you might take. Before you know it, youll be a scientist.

Frontier Essay Example | Topics and Well Written Essays - 500 words
Frontier - Essay Example Turner paints the slavery struggle as just an incident that has a lot of meaning to the American history during the expansion of the westward. Slavery was more rampant just before the end of civil war, but did not become of exclusive importance. This effectively portrays the slavery struggle as an insignificant factor in American history. The most significant impact of the frontier on American history, which Turner unconvincingly contends is the promotion of democracy. A complex society is precipitated by the wilderness, into a kind of primitive organization based on the family. The tendency is anti-social. This produces hostility to control. The tax-gatherer for instance is viewed as a representative of oppression. The same conditions, according to Turner help in explaining the difficulty of forming a strong government in the period of the union. The frontier individualism has from the beginning, therefore promoted democracy. For example, ââ¬Å"the frontier States that came into the Union in the first quarter of a century of its existence came in with democratic suffrage provisions, and had reactive effects of the highest importance upon the older States whose peoples were being attracted thereâ⬠(Turner 5). Turner concludes that the non-geographical elements of the frontier nevertheless evidently continue with the current phase of globalization that is essentially Americanization. Indeed, Turner reckons that the frontier is the line of most rapid and effective Americanization. According to Turner, another example of how the frontier promoted democracy is given of western New York that forced an extension of suffrage in the constitutional convention of that State in 1821 (Turner 5). In that regard the Turnerââ¬â¢s thesis is not convincing because the impetus appears a new wave in the American imperialismââ¬â¢s history. Despite being perceived as an encouragement to the overseas expansion of the United States and promotion of democracy, it does

Art Essay Example | Topics and Well Written Essays - 250 words - 4
Art - Essay Example because art involves designing and using creativity in making objects that triggers memories, educate, communicate, and trigger emotions (Harrison 11). In fact, it can be argued that art involves several human activities. It is not a must for art, to have specific qualities for it to qualify to be art. However, certain things like color, texture are considered to differentiate between good and bad art. What I value or look for in art is beauty, uniqueness, and inherent meaning. Beauty in art captivates people. When art is created to convey certain meaning such as political and emotional trigger, I consider that to be an ideal art. I expect art to act as a communication tool to different groups of people. For example, a toy created for children should act as an educative element to children. Cartoon drawings should act as warning, informative, and above all bring about joy in peopleââ¬â¢s lives. Art should be used to represent beliefs and norms of cultures, whereby cultures would be represented in artistic

Accounting information system Essay Example for Free
Accounting information system Essay An entity relationship (ER) diagram is a documentation technique used to represent the relationship between entities. Entities are physical resources (automobiles, cash, or in-ventory), events (ordering inventory, receiving cash, shipping goods), and agents (sales-person, customer, or vendor) about which the organization wishes to capture data. One common use for ER diagrams is to model an organizationââ¬â¢s database, which we examine in detail in Chapter 9. Figure 2-14 shows the symbol set used in an ER diagram. The square symbol represents entities in the system. The labeled connecting line represents the nature of the relationship between two entities. The degree of the relationship, called cardinality, is the numerical mapping between entity instances. A relationship can be one-to-one (1:1), one-to-many (1:M), or many-to-many (M:M). 2 If we think of entities in the ER diagram as files of records, cardinality is the maximum number of records in one file that are related to a single record in the other file and vice versa. Cardinality reflects normal business rules as well as organizational policy. For instance, the 1:1 cardinality in the first example in Figure 2-14 suggests that each salesperson in the organization is assigned one automobile. See more: Unemployment problems and solutions essay If instead the organizationââ¬â¢s policy were to assign a single automobile to one or more salespersons who share it, this policy would be reflected by a 1:M relationship. Similarly, the M:M relationship between vendor and inventory in Figure 2-14 implies that the organization buys the same type of products from one or more vendors. A company policy to buy particular items from a single vendor would be reflected by a 1:M cardinality. System designers identify entities and prepare a model of them, similar to the one presented in Figure 2-15. This data model is the blueprint for what ultimately willa

Salem Witch Trials Essay -- essays research papers
Deep inside a town in Massachusetts innocent people were accused of the devilââ¬â¢s work, witchcraft. God-fearing Puritans took it upon themselves to exterminate Satanââ¬â¢s followers influenced by anti-witch ideas and other sources including books and the words of various priests. Over 100 people were given unfair trials; many were jailed while quite a few were lynched. Although the Salem witch trials are considered one of the depressing parts of American history the topic also provides an interesting look at how people thought and lived during the colonials times. à à à à à The practice of capturing witches didnââ¬â¢t start at Salem. For centuries Europeans had been catching supposed witches and burning them at the stake. In 1492 two priests were elected by the Catholic Church to write a book on the evils of witchcraft. The book was read widely and told people how witches worked for the devil and the various ways they could torture and kill people. After reading this book and another anti-witchcraft book, Relating to Witchcraft and Possessions, by Cotton Mather(a local priest) which encouraged colonists that even torture was fine to convict people of sorcerery(since real witches couldnââ¬â¢t feel pain) it was no wonder that the Puritans of Salem took it upon themselves to expel witches in Godââ¬â¢s name. Another cause of the trials was a problem brewing in Salem itself. For many years Salem Town and Salem Village had been separate parts of Salem. Salem Town had the rich m...

Odysseus as an Epic Hero Essay
What is an epic hero? Homersââ¬â¢ ââ¬Å"Odysseyâ⬠is about an epic hero named Odysseus and his quest home. ââ¬Å"The Odysseyâ⬠begins after the Trojan war had left Odysseus trapped, pointlessly seafaring for 10 years after angering Poseidon, the god of the sea. He tries desperately to return home to Ithaka and his wife, Penelope, and newborn son, Telemachus. Odysseus then has many hardships upon which he overcomes through his intelligence and wit. Odysseus is an epic hero because he is intelligent, he listens to the godââ¬â¢s advice, and he is witty; able to think on his feet. With the help of the gods he can survive things most men couldnââ¬â¢t. First, nearing the end of the Epic, Odysseus continues to use his intelligence to overcome obstacles and hardships. Upon one attempt to return home, Odysseus must pass the island of the Sirens. He has his men plug their ears with beeswax but not before he tells them his place in the plan: ââ¬Å"Take me and bind me to the crosspiece half way up the mast; bind me as I stand upright, with a bond so fast that I cannot possibly break away, and lash the ropeââ¬â¢s ends to the mast itself. If I beg and pray you to set me free, then bind me more tightly still. Even though Odysseus gives into the weakness of the sirensââ¬â¢ song, he is unable to escape from the bonds of the rope and his previous intelligence saves him. Once he arrives in Ithaca, Odysseus once again uses his intelligence to overcome his suitors and reclaim his estate. When he first encounters the people of his land, he wisely chooses to remain anonymous, avoiding an unplanned struggle or fight. Odysseus then reveals himself to his son and few servants to plan an attack on the suitors. At a contest to see if anyone can string Odysseusââ¬â¢s bow, the hero plans his attack after stringing the bow and firing on the suitors. His son and servants have the other arms and they massacre the entire group of suitors. This was one of Odysseusââ¬â¢s final acts of brilliance to conclude the epic. Furthermore, there are many instances throughout the epic where Odysseus takes the advice of the gods to overcome the obstacles he is faced with. One of the first events is when Odysseus encounters Aeolus, the god of winds. Many men would not trust this god and not accept his secret bag of wind, believing it would be a plague of some sort. But, Odysseus accepts Aeolusââ¬â¢ bag of winds and treats him with hospitality. Another instance where Odysseus accepts the godsââ¬â¢ guidance is when the hero listens to Hermes on how to overcome Circe: ââ¬Å"But Hermes met me, with his golden wand, barring the way-a boy whose lip was downy in the first bloom of mankind, so he seemed. He took my hand and spoke as though he knew me. â⬠By Hermes insight, Odysseus eats the food that is given to him and patiently waits for the right time to strike. Odysseus subdues Circe and forces her to free his men from the bondage of swine. After living in luxury with Circe for a year, he listens to her advice on how to return to his homeland of Ithaca. Finally, one of the first obstacles Odysseus conquers is the defeat of the Cyclops. Once trapped in the cave of the one-eyed monster, Odysseus must devise a plan and fast, the giant had taken to consuming his men. This is where Odysseusââ¬â¢ wit comes into play. Cunningly, Odysseus gets the Cyclops drunk and allows him to fall into slumber. He then blinds the Cyclops with a red-hot spear, knowing intelligently enough that if he kills the Cyclops they will be trapped forever. Searching for help, the giant opens the cave. Earlier, Odysseus says: ââ¬Å"My name is Nobody: mother, father, and friends, everybody calls me Nobody. When the blinded giant is seeking help from his brothers, he proclaims that, ââ¬Å"Nobodyâ⬠blinded him. Therefore, Odysseus and his men escape with their lives by the means of this heroââ¬â¢s wit.? In conclusion, through this intelligence and wit with advice from the gods, Odysseus overcomes all of his obstacles against all odds. Being a true hero, the Achaeans look up to Odysseus as a role model with his intelligence, wit, and godly insight. It is because of these three traits that Odysseus is considered an epic hero and is never to be forgotten.

The tutorial gives a brief introduction to the PicoBlaze microcontroller, and then steps through the following: â⬠¢ â⬠¢ â⬠¢ â⬠¢ Writing a small PicoBlaze assembly language (. psm) file, and stepping through the process of assembling the . psm file using KCPSM3. Writing a top level VHDL module to connect the PicoBlaze microcontroller (KCPSM3 component) and the program ROM, and to connect the required input and output ports.Connecting the top level module inputs and outputs to the switches, buttons and LEDs on the Spartan-3E board. Downloading the program to the Spartan-3E board using the Project Navigator software. 1. 1 Design Functionality The code written in this tutorial reads the values of the four switches and the four push buttons, and displays the current values on the eight LEDS. 1. 2 Relevant Documentation Before commencing this tutorial, it would be helpful to download the Spartan-3E FPGA Starter Kit Board User Guide [1], and the PicoBlaze 8-bit Embedded Microcontroller User Guide [2]. 1. Pre-requisite Knowledge Before commencing this tutorial, the user should work through ââ¬Å"The Spartan-3E Tutorial 1: Introduction to FGPA Programmingâ⬠[3]. 1. 4 Scope This tutorial is designed to help the user who is just starting to ââ¬Å"get intoâ⬠using the PicoBlaze with the Spartan-3E. It steps through the process of creating a very simple PicoBlaze program, running the assembler, putting the VHDL components together in Project Navigator, and downloading the final program to the board. It is not designed to be a tutorial on VHDL syntax or to provide detailed information on the PicoBlaze.For help with VHDL, the user can consult with a number of textbooks on the subject, such as [4,5], or find help online. The book by Chu [6] is also a useful reference for the Spartan-3 with many useful examples. Reference designs for the Spartan-3E can also be found here [7]. For detailed information about the features and instruction set of the PicoBlaze, the user can consult the documentation in [2,8]. Xilinx Spartan-3E Project Navigator Version 14. 3 Tutorial 2: Introduction to Using the PicoBlaze Microcontroller 16 Xilinx Spartan-3E Project Navigator Version 14. 3Tutorial 2: Introduction to Using the PicoBlaze Microcontroller 17 2. 0 Equipment The following are required to work through this tutorial: â⬠¢ The Xilinx ISE Project Navigator software. Version 14. 3 was used in this tutorial, but older versions of the software can be used. The software can be downloaded with a free WebPack license from the Xilinx website, http://www. xilinx. com/. The user will need to register and log in. The Spartan-3E Starter Kit, including the Spartan-3E development board, power cable and USB cable for PC connection. The Spartan-3E development board is shown in Figure 2. 1.The Picoblaze 8-bit Microcontroller software. The software can be downloaded for free from the Xilinx website, http://www. xilinx. com/. Again the user will need to register and log in. If a 64-bit machine is being used, software which can run 32-bit DOS programs, such as DOSBox, will be needed to run the KCPSM3 executable. DOSBox can be downloaded from http://www. dosbox. com/. â⬠¢ â⬠¢ â⬠¢ Power JTAG ON/OFF Reset Button FPGA USB LCD LEDs Push Buttons Figure 2. 1: Spartan-3E Development Board. SW0-3 Xilinx Spartan-3E Project Navigator Version 14. 3 Tutorial 2: Introduction to Using the PicoBlaze Microcontroller 18 . 0 Background ââ¬â The PicoBlaze Micocontroller The PicoBlaze is an 8-bit RISC microcontroller which is specifically designed and optimized for the Spartan-3 family. One of its main advantages is its small size, requiring only 96 FPGA slices. It is provided as a free, source-level VHDL file with royalty-free re-use within Xilinx FPGAs [2]. Figure 3. 1 shows that the PicoBlaze consists of two components. The KCPSM3 component provides the ALU, registers, scratchpad RAM etc. The Block Memory (Program) component stores the instructions to be executed. This typically consists of a Block RAM, of 1024 bytes in size.Figure 3. 1: PicoBlaze components [8]. The basic design process using the PicoBlaze follows the steps below: 1. A PicoBlaze program is written in assembly language. This file is given the extension . psm. 2. The KCPSM3 assembler is run on the . psm file, and a VHDL file (extension . vhd) which embeds the instructions in the Block Me mory component, is output. The name of the . vhd file will be derived from the name of the . psm file, i. e. , if the . psm file is myprog. psm, then the . vhd file will be myprog. vhd. 3. The VHDL code for the Block Memory and KCPSM3 modules is loaded into Project Navigator.Further VHDL code will need to be written to connect the two modules and interface to the outside world. 4. The project is compiled using the Project Navigator Software, and ultimately downloaded to the Spartan-3E board (or other target hardware). Figures 3. 2 and 3. 3 show the VHDL component declarations for the KCPSM3 and Block Memory respectively. Note that the name of the Block Memory component is derived from the name of the original . psm file, i. e. , if the . psm file was myprog. psm, the Block Memory component will be called myprog.

In addition, it is possible to download a new program into the Block Memory, using the JTAG port on the Spartan-3E board. This can provide a convenient means to update the program without having to recompile the VHDL code in Project Navigator. This is not covered by this introductory tutorial, and the user can refer to documentation such a s [3] for more information.

If you are using a 64-bit machine and attempt to run KCPM S3 in a DOS Command Prompt window, the error message shown in Figure 4. 8 will appear. Figure 4. 8: Error message which appears if it is attempted to run KCPSM3 on a 64-bit machine. One way to work around this and run KCPSM3 is to use the DOSbox software, which can be downloaded from http://www. dosbox. com/. 1.Download and run DOSBox. 2. Mount the working directory and change into this directory. When DOSbox is started up, a command window which resembles the DOS Command Prompt window appears. However, it is first necessary to mount the working directory to a drive letter before being able to enter this directory and run programs. This is done with the mount command: mount Figure 4. 9 shows the commands entered to mount and change into the working directory. In this case, the working directory is mounted as drive letter c. The command c: is then used to change into this directory.

It can be seen that Project Navigator colour codes the text of VDHL files, to make them easier to read. Comment lines, which start with ââ¬Å"- -â⬠are displayed in green. Reserved words of the VHDL language are displayed in blue, while VHDL types are displayed in red.Everything else is left as black. tutorial in Sources window Source code for tutorial. vhd appears in this tab Figure 5. 9: Source code for tutorial. vhd is displayed in a tab. A close up of the code for the tutorial entity is shown in Figure 4. 10. Note that this corresponds to the Block Memory (Program) component of Fi gures 3. 1 and 3. 3. Figure 5. 10: tutorial entity. Xilinx Spartan-3E Project Navigator Version 14. 3 Tutorial 2: Introduction to Using the PicoBlaze Microcontroller 38 2. Double-click on kcpsm3 in the Sources window, to display the source code for kcpsm3. vhd.A close up of the code for the kspsm3 entity is shown in Figure 5. 11. Note that this corresponds to the KCPSM3 block of Figures 3. 1 and 3. 2. Figure 5. 11: kcpsm3 entity. Xilinx Spartan-3E Project Navigator Version 14. 3 Tutorial 2: Introduction to Using the PicoBlaze Microcontroller 39 5. 5 Adding a top_level Entity VHDL code still needs to be written to tie together the kcpsm3 and tutorial entities, and also to interface with the Spartan-3E board. We will create a file called top_level. vhd for this purpose. 1. Select Project>New Source as shown in Figure 5. 12. The New Source Wizard will appear. > Figure 5. 2: Adding a source file to the project. 2. Select Source Type as VHDL Module. 3. Enter the file name as top_level, a nd enter the location of the file (same as the project location entered earlier. 4. Verify that the Add to project box is checked. shown in Figure 5. 13. The New Source Wizard should now appear as Xilinx Spartan-3E Project Navigator Version 14. 3 Tutorial 2: Introduction to Using the PicoBlaze Microcontroller 40 Figure 5. 13: New Source Wizard, Select Source Type. 5. Click Next to go to the Define Module window. 6. Define the ports (inputs and outputs of the design) by entering the information as shown in Figure 5. 14.These ports are described as follows: â⬠¢ â⬠¢ â⬠¢ switches will be an input consisting of 8 bits, and will be connected with the 4 slide switches and 4 push buttons on the Spartan-3E. clk will be an input consisting of 1 bit, and will be connected to the clock input. LEDs will be an output consisting of 8 bits, and will be connected with the LEDs on the Spartan-3E.

Xilinx Spartan-3E Project Navigator Version 14. 3 Tutorial 2: Introduction to Using the PicoBlaze Microcontroller 4 5. 6 Editing the top_level Entity 1. Double-click on top_level in the Sources window to display the file, top_level. vhd in a tab. The code for top_level. vhd is shown in Figure 5. 17. entity architecture Figure 5. 17: top_level. vhd, as displayed in Project Navigator, before editing. The code in Figure 5. 17 contains an entity and an architecture section. The entity section defines the inputs and outputs of this hardware block. In this case these have been automatically added using the New Source Wizard. The architecture section still needs to be written for this module. 2. Replace the architecture block in Figure 5. 7 with the code in Figure 5. 18(a) and (b). This code is a trimmed down version of the Initial Design for the Spartan-3E FPGA Starter Kit Board (the original design shipped with the board), downloaded from [7]. For reference the complete code for top_level. vhd is listed in Appendix A. Note that where VDHL code is listed in this tutorial, the same colour coding as Project Navigator is used, to assist with readability. 3. Save the file by selecting File > Save from the main menu.
