African People in the Global Village Essay

Certain things happen in one’s life, whether one likes them or not. You can not stand apart from it; you need to experience the process of going through it. Let me give the example of a car. It has two types of movements-forward movement and lateral movement. The energy (petrol, gas etc. ) relates to forward movement, without which the car can not start. You have no control over it. As for the lateral movement, you as the individual driving the car, have the control over its speed-you can drive it through the royal road, narrow lane, drive at 120 kms. per hour or just 30 kms- or not drive at all. Just lock it in the garage for days together! You are living in a changing world- very fast changing world. The modified lifestyles, due to industrial revolution, the modern materialistic civilization, the internet revolution, are mind-boggling. You need to run your race, accelerate the steps, clear the hurdles and move towards the goal. Stop in between at your own peril! Survival under tough conditions and competition are not magic. Nor an element of chance is involved. The wise saying goes, â€Å"When the going gets tough, the tough gets going. † Survival will be extremely difficult for the African people in the global village, unless tangible steps, all-comprehensive projects are drawn up and implemented with speed and imagination, by responsible leaders and people. The test of the leadership lies in involving the people actively and willingly in such projects. African people in the Global village- the summary: Africa is a big continent. The vastness of the area, multiplicity of ethnic conflicts, the fierce tribal loyalty prevailing even today, the religious factors, the difficult past, the historical factors some of which do exercise telling effect on the African society and mind-set even today, render the solution difficult. John K. Marah, who is the Associate Professor and Coordinator in the African and African-American Studies Department at SUNY at Brockport, makes a concerned and well-studied approach to offer solution in the book African People in the Global Village and the possible direction which they need to follow. Moreover, due to historical reasons, African people (the black race) are spread all over the Western World. They are a noticeable political force, an awakened society in Countries like USA. Marah categorically opines that it is no use brooding over the past, its failures and bitter memories. He does the examination of the present situation from an open-minded perspective. Confrontation at every stage is not going to help the cause of the African people. They have to know their place and find out the ways and means to evolve within the global village. He calls it ‘multidisciplinary approach and well-rounded understanding’. Right from the beginning of the book, Marah is aware that he is up to a difficult task, and the subject matter of the book, â€Å"African People in the Global Village,† can not be discussed in isolation. Yet, he takes the direct plunge into the serious subject matter. The book has neither a preface nor a forward. For a highly sensitive and complicated subject like this, author’s detailed background would have been a helpful factor, but that is not given in the book. The biographical sketch is not provided. Nevertheless, it is a determined and well-informed effort to broach the subject matter which is so vast viewed from tough, social, political, historical, economic and cultural perspectives. The problems are ever growing like the octopus expanding in many directions and only a radical solution like Pan-Africanism is the solution according to Marah. But, to define Pan-Africanism is not the easiest of the tasks. He concludes that African people have no other choice but to move forward at a rapid pace, with the qualities of head and heart-be dynamic without destruction! Marah begins his book on a tough note. â€Å"African Sensibilities in the Global Village. † He fails to give a clear message in this chapter– one can not expect him to do so. The subject matte is so vast, complicated and the concern of Marah to offer a desperate solution to a desperate situation can be seen. He realizes his limitations-the subject matter he is up to tackle can not be discussed in isolation—by referring to the conditions of the African people alone! Their so-called more fortunate brothers in America also have their own problems and deep fears on many vital and fundamental issues! It would be prudent to link the problems of the black people of America with the black people of Africa, as Marah rightly argues. At the end of the chapter he specifies, `in this book we examine the position of African people in Africa and the United States with particular emphasis on some of their salient predicaments in the global system†¦. ‘( Marah, 1998 p. 16). Having said this, Marah realizes about the uphill task ahead for him, for he fails to give appropriate solutions or alternatives. The discussions in the book naturally and essentially take him to outside Regions, where black race matters. In chapter 4, he discusses this aspect in detail. The black people issue is like the issue of a flowing river. It can not be discussed in parts. The river as a whole will have to be discussed to understand it. Its beginning, its course of flow and the area through which it passes, etc! Marah has a message for the black people and the leadership. Some inspiring political and economic leadership has to take over and lead, to achieve the set goal. He makes a case for the entry of socio-spiritual leadership to play its role, because what the Global Village Africa needs is not only fine projects but fine individuals to implement the projects-that is what he means when he says about the ability of the people to survive in a new environment. New skills are required to push ahead in such circumstances. The thought process of the people requires a new orientation and change. When the thoughts are changed, the mind is changed; when he mind is changed, the man is changed; when the man is changed, the society is changed; when the society is changed, the nation is changed; when several such nations are changed, the African continent will change for the better! Then only the African people in the Global Village will achieve plenty and prosperity. For survival, wherever may be it, certain basic skills are necessary, and African People in the Global Village, are no exception. Education gets top priority—the ability to read with understanding. Speak boldly so hat others can understand and appreciate your problems. It is not that you expect sympathy from others; but in a democratic society, when your fundamental rights are guaranteed by the Constitution, you need not be condemned by anyone either-you need not live your life like a baked potato always. The majority of the ills of African People are due to poor response to globalization. This lethargy is frightening and it will continue to bother and trouble them in every aspect of life, unless something tangible is done as quickly as possible. African people will head for an economic and social disaster and moral doom, if they do no wake up and react speedily.

My Greatest Fear

My biggest fear is something that keeps me up many a night. I have a fear of heights, of drowning and of several other tangible things. However, I believe that when confronted with those, I will probably be able to deal with them in some form or another (don't ask me how you deal with a fear of heights, but I will). This one that I consider to be my biggest is like a disease, something I haven't figured out how to deal with. The worst part is that I am not sure there even exists a solution to it.For me, the fear of nonperformance, the fear of failure, the fear of not living up to expectations (my own, more than anyone else's) is what I consider to be my biggest in life. I can attribute a lot of my personality traits and obsessive behaviors to this fear. It may be a convenient excuse, but without any other valid or obvious reasons, I would like to apportion a significant part of the blame to this fear!I think as the years have gone on and as I have moved from one job to another, from one country to another, the pressure has only mounted and the fear of not stepping up has only increased. I mean, you spend thousands of dollars on an education and then several more thousand on another†¦ All you expect is for that to pay off, for your skill set to broaden, for your knowledge base to widen and for you to only rise and grow in life. How can you not know the answer to something? How can you not be able to step up to a challenge or a question posed by someone? How can you not perform a certain job that you should have received the training for?And the funny part is that I never realized this until very recently†¦ until it was pointed out to me by a friend. I was grumbling about not enjoying my job (a fairly recurring theme these days) and my current role, and one of my closest mates from the MBA simply asked me, â€Å"Is it the job? Or is it your desire to be perfect and to expect to always want to outperform that is not making you like it?† And then I thought about it — yes, maybe he was right. Maybe I was expecting to know it all and to hit the ground running right from the outset; I thought I had the skill and knowledge to do it all and didn't want to take the intermediary learning step†¦ And when I didn't, I suddenly felt as though I was underperforming! I wasn't living up to  expectations†¦ And worst of all, I was failing! Fear realized, multiple sleepless nights followed.Having this fear may be a good thing (to some extent). It could also, however, be a bad thing, but it is something that has come to frame my thought process, my actions and my drive over time. I am thankful for it in many ways, and believe that I may not have done all that I have over the last several years without this sense of fear†¦ But now that I know, maybe it is time to develop a method of controlling it, of reining it in! Too much of something is never a good thing, right? Or at least that's what I was always told when I went to the fridge for more candy! Is there then another fear that surpasses the fear of failure?So, even though I call this my biggest fear, and admit to it being so, I ain't jumping off planes or climbing the Himalayas†¦ So for those who have tried to convince me to do some of these wacky things in the past, you may want to try again!

Interactional View Theory Essay

This theory states that within family relationships there can often be misconceptions between each family member and the problem can only be transformed when addressed by outside members of the family (or situation), or simply stepping outside the situation yourselves and looking at all possible aspects that way, or reframing. Watzlawick claims that through the repetitive actions of a family system, a self- ­regulating, inter- ­depending network of feedback loops guided by member’s rules, we tend to stick to a status quo, or a family homeostasis, when dealing with issues within our families. In doing that, we often automatically assume, or put a label on, a situation to be how we see it from our personal views rather than looking at the whole picture and everyone’s views who are involved. Once we take that outside- ­looking- ­in approach we have to take into consideration both sides of the communication in the situation: the content of the situation, the report part of a message (verbally), and the relationship between members communicating, the command part of a message (nonverbally). In doing this as well as analyzing all aspects of the situation we can eventually come to an agreement on how to approach and solve the actual issue. Growing up with a health practitioner as a parent, getting sick is never anyone elses fault but your own and sympathy is almost never present in those situations. I recently had an extreme food- ­ poisoning incident which caused much havoc in my family, but the process of analyzing and solving this issue is a perfect example of Watzlawick’s theory. A few years ago my mom decided to go back to school and study healthy living, diet, and the ways of an organic, raw vegan. This changed her whole life, my whole pantry, and the way she approached almost any situation. Anytime something does not go the way it should having to do with my body, energy, moods, etc. if I go to my mom for advice the answer is always about diet, sleep patterns, or other healthy living styles. Which is accurate and understandable to a certain extent but, in mine and my stepdad’s minds, it does not apply to every situation. I do eat very healthy compared to the average person and I try to not eat a lot of meats, and especially not red meats, but on occassion I do enjoy treating myself to, what I call, a â€Å"cheat meal.† A few months back when visiting friends out of town, I decided to go all out and try this â€Å"world- ­famous† burger at a local burger joint. Might I say, it was quite the burger, but the aftermath was seven days of pure distaste, pain, and regret. Of course when coming to my mom for advice on the situation she immediately put all blame on me for not choosing â€Å"wisely† on my food decisions. My stepdad, on the other hand, eats a good amount of red meats and had actually been to this particular restaurant many times before, having no issues. He said i probably just got a bug from touching the â€Å"world famous† burger joint door handles and putting my hand to my face, or something of that sort. My take on the situation was different from both of theirs. I thought it was all in my mind because I am typically against eating red meats and i violated my self morals therefore causing me to feel guilty to an extent where I caused myself to actually be sick. Hearing each member’s take on the situation caused havoc and an unnecessary issue that drove away from the actual problem. Until we all sat down and open- ­mindedly listened to each person’s reasoning did we all realize how ridiculous the whole situation was, and how no one actually knew the official cause of my illness but arguing about what might be because of our personal stances was just silly and almost irrelevant. When approaching the situation, as Watzlawick predicted in his theory, my mom, stepdad, and I, originally, all took our individual opinions and pushed them on one another assuming that they were the only way. My mom saying the my stepdad was an enabler, one whose non- ­assertive behavior allows others to continue in an addiction or other wrong- ­doing, and in defending himself, my stepdad saying she was biased because of her personal beliefs on eating habits. Once we agreed to sit down and talk about each person’s perspective on things using metacommunication, communication about communication, and taking into consideration why each of us acted a certain way and how it might have affected the others, we could finally come to agreement and be at peace. We decided that if we all would have approached each other in a more open- ­minded, understanding manner using one- ­across communication, conversational moves used to neutralize or level control within the exchange, rather than trying to one- ­up communicate, place conversational moves on each other to gain control of the exchange, with each other, it would have been a symmetrical interchange, an interaction based on equal power, and the conflict might not have happened at all. I find the Interactional View Theory to be quite on point, and though Griffin found much to critique I might have to disagree and say, while the theory may not be absolutely perfect and one- ­hundred percent accurate in every situation, it does apply to most of, at least, my family controversies, for example, this particular incident. From this theory I was made aware of how often I am to quickly ignore my parents’ responses as initial reactions to them being repetitive and almost biased in their advice, and how I can be more open- ­minded in those situations. I was also made aware of how to think and approach my parents in certain situations, such as food poisoning, to trigger a more calm and open- ­minded response from them. I enjoyed reading, comparing, and analyzing this theory and will begin to consciously apply it to my future conversations with my family members as I did in the food poisoning example, but this time before the incident can happen or get worse.

200 Villagers Houses Burnt Down Again Near Barrick Gold Mine in Papua Essay

200 Villagers Houses Burnt Down Again Near Barrick Gold Mine in Papua New Guinea - Essay Example This behavior of the national court is known to be a result of Barrick Limited request. The expected impact on the company as a result of such unethical behavior will have severe impact on the company’s reputation, sales and stock prices as it has violated human rights of the citizens of Papua New Guinea and also demonstrated lack of environmental responsibility. However, this extent of this impact depends on the extent of public awareness and international community/communities about this issue. Barrick Gold Corporation cannot be considered as an ethical corporation as it has violated the human rights of the villagers of Papua New Guinea and also has failed to do business in environmentally friendly and sustainable manner. Barrick Gold operates its but Porgera subsidy as a joint venture with the local government. It is possible to suggest that actions undertaken against the local citizens of Porgera village were initiated solely by the government of Papua New Guinea, however, it doesn’t relieve the company from ethical responsibility. One of the competitors of Barrick Gold is Sumatra Copper & Gold plc. This company has established a detailed Code of Business Conduct, which covers â€Å"a wide range of business practices and procedures† and sets up guiding ethical principles for all employees and managers of the company (Sumatracoppergold.com, 2014). Also, the company seeks to minimize the environmental risks at the company’s sites and comply (Sumatracoppergold.com, 2014), while Barrick Porgera Gold mine obviously fails to do so, despite its claims (Barrick.com, 2014). In order to address the problem there should be undertaken some serious measures and initiatives. First of all the company has to adjust its financial plans to the sustainability principles, which pursue not only economic benefits, but also social and environmental benefits. Thus, the company has to adjust the whole strategy to become socially and

Internal Analysis of the NBA Assignment Example | Topics and Well Written Essays - 2000 words - 1

Internal Analysis of the NBA - Assignment Example The paper will begin by analyzing the capabilities and resources NBA had before the 2010-2011 season; the analysis will be from a case study done by Coulter. The capabilities and resources in the 2010-2011 seasons will be analyzed. The best approach to the internal analysis of NBA will be discussed. The National Basketball Association (NBA) has undergone tremendous changes from a domestic sport to an international commercial sport and this indicates a major understanding of the resources and capabilities. All the success and efforts are attributed to the NBA commissioner David Stern who has helped NBA become a global brand. Professional basketball began in the mid-1990s and NBA gained the international game appeal. There are key players in the NBA who have sparked international interest. These players include Yao Ming of China, Dallas Mavericks’ Dirk Nowitzki of Germany, Pau Gasol of Spain, and Tony Parker of France, Denver Nuggets of Brazil, Gordan Giricek of Croatia and Darko Milicic of Serbia. All the mentioned are international basketball players. It is estimated that out of all the players in the NBA, 64 players come out of the United States territory. Other than the international players, NBA has taken its games globally. The NBA league has held several preseason games in the Latin America, Asia, and Europe. Among the major plans by the commissioner of NBA was the creation of multiple teams in the European region before the end of the 2000 decade. The NBA league has faced challenges like the retirement of Michael Jordan and the cancellation of almost a third of the league games in the mid-1 990s. The challenges almost crashed the NBA league. Stern, the commissioner of NBA addressed the issues by looking at what the NBA had to offer, that is the resources and capabilities.  

My feet is rested but my soul is at rest Essay Example | Topics and Well Written Essays - 750 words

My feet is rested but my soul is at rest - Essay Example Evidently, the thesis is congruent with Martin Luther’s letter as he communicates utmost peace within himself despite of the adversities he encounters. This also serves as the best thesis as the protagonist of the document advocates for it after hearing it from an old woman. Despite of the statement’s ungrammatical profundity, Martin uses it against the white moderates. It portrays physical, ethical, and spiritual aspects of the Black Civil Rights Movement. The statement communicates to the white moderates. His actions and experiences seem to derive influence from this statement. I write this paragraph to create an introductory aspect about the origins of the thesis. Reading Luther’s letter from prison involved cognitive processes of responding. The critical response and analysis took diverse techniques that contributed to the formulation of the thesis. The foremost technique involved a superficial reading of the entire letter. This provided key denotations that contributed to the thesis â€Å"My feet is rested but my soul is at rest.† After a survey of the letter, the key events spell Martin Luther’s will to suffer for his people. He makes immense sacrifices to advocate for freedom in Birmingham. The black race was subjected to intense segregation by the whites. Therefore, the thesis derives its form from these major events. This attributes to the fact that his feet rest in prison after his engagement, and his soul rests upon his accomplishment towards advocating for freedom and equality in Birmingham. I create this paragraph to exemplify an aspect of comparison that led to the thesis formulation. Therefore, the thesis â€Å"My feet is rested but my soul is at rest,† derives its form from contrasting different events within the letter. Comparison is a key technique that seeks to expound on relative sides, for a uniform final implication. I used this technique I formulating this paragraph. Martin Luther formulates an an alogy in his paper that speaks of religious leaders in Christianity. These leaders involve Jesus, as well as the disciples. He compared his sacrifice with the one that was found amongst the religious leaders. This brought an aspect of comparison that contributed to the thesis. Through comparison, Martin Luther and the religious leaders have immense similarity in their capability to sacrifice for their people. Their souls rest even during adversities in the quest for the needy. The comparison contributes to the thesis â€Å"My feet is rested but my soul is at rest† immensely. Therefore, comparison is a key technique in thesis formulation. I formulated this paragraph to take a comparative nature with the aim reflecting the thesis as the ultimate implication of the relationships. Insight observation is a key technique of thesis construction that I use in the composition of this paragraph. This technique involves the evaluation of history and chronology of a text. The depicted gr adual sequence of events has a major contribution to the thesis. The thesis gains more authenticity after exploration of chronology and history. Martin reflects a chronological development of segregation through different times. Segregation and injustice has been a major concern within Birmingham. This gives him propulsion to undergo adversities for the sake of his people. He meets an old lady that utters striking words to him; â€Å"My feet is rested but my soul is at rest.† This explains Martin Luther’s attitude towards advocacy for freedom. He lets his feet rest

Rigid Bodies and Application to Snooker Assignment

Rigid Bodies and Application to Snooker - Assignment Example In this project I made a study of main laws and principles of rigid body dynamics from the practical and theoretical point of view: as solutions to theoretical and practical exercises are provided. It required review and deeper study of vector analysis and analytical geometry. Rigid body in mechanics is a system of material points, which doesn't change in time. So it's an idealized system for which the distance between its particles remains constant in time under any motion. Phenomenological mechanics considers rigid body to be a solid matter, in which particles are subjected to internal forces in the form of normal and tangent tensions. Such tensions are caused by external deformations. In case they're re no deformations, there are no tensions inside rigid body. In many cases deformations are so small that can be neglected. So such model is an idealized rigid body, which is not able to deform and even though internal tensions can take place because of external forces. Rigid body is a mechanical system with six degrees of freedom. In order to define the position of a rigid body it's enough to know the position of at least 3 points: A, B, C, which do not belong to one line. In order to prove that rigid body is described by six degrees of freedom we have to take point D. ... (XA-XB)^2+(YA-YB)^2+(ZA-ZB)^2=AB^2=const (XC-XB)^2+(YC-YB)^2+(ZC-ZB)^2=CB^2=const (XA-XC)^2+(YA-YC)^2+(ZA-ZC)^2=AC^2=const Because the lengths of sides of triangle ABC remain the same. So only six coordinates are left independent - rigid body has 6 degrees of freedom. If the body has fixed points the number of freedoms degrees reduces. If rigid body is fixed in one point - it has 3 degrees of freedom, if rigid body can only rotate around one axis is has one degree of freedom, if a body can slide across axis it has two degrees of freedom. In order to understand how x(t) and R(t) change over time we should remind the following formulas: Resultant is v= V+ [w, R] (using vector properties). Kinetic energy of a rigid body is total kinetic energy of rotation plus total kinetic energy of motion: T=.5 mv^2 + 0.5Iw^2 Where I is moment of inertia of a rigid body (mass analogue for rotational motion) Moment of inertia is defined as I=miRi^2. Moment of inertia is additive so moment of inertia of a rigid body is formed from the sum of inertia moments of its parts. Any body, independently from rotational motion or rest has definite moment of inertia. Mass distribution in the limits of a body can be characterized by density: p=m/V So moment of inertia can be expressed as I=piRi^2Vi, if density is constant: I=pRi^2Vi In limit it can be expressed in the following integral: I=R^2dm=pR^2dV The inertia tensor is a set of nine values (which can be written in the form of 3X3 matrix), which shows the dependence of shape and distribution of mass in the rigid body caused by its rotational motion. It's often explained as a scaling factor between angular momentum and angular velocity.1 Inertia tensor matrix has the following structure and its components are calculated

Is China in an asset bubble Yes or no Why or why not (Particularly Assignment

Is China in an asset bubble Yes or no Why or why not (Particularly real estate bubble) - Assignment Example Fan Gang joined the regional officials in expressing their concern over the surging prices of assets (Leung & Wong Para 1). According to Forsythe and Hamlin, there is a sprout of empty buildings across the nation as firms with access to 1.4 trillion dollars- given in new loans in 2008- build skyscrapers. This has led to the Chinese property’s market bubble. James Chano, the hedge fund manager, says that there is a monumental asset and fixed asset, including real assets, bubble in China right now. He adds that deflating such an issue will be quite difficult at best (Forsythe & Hamlin Para 4). The Chinese government, since October 2010, has increased asset bubbles three times. This suggests fears of a shaping asset bubble and high inflation. China is highly dependent on oil and her growth rate is higher than that of Japan. If the worldwide prices of oil continue rising, China could be in some serious trouble. Moreover, there are numerous IPOs (Initial Public Offerings) in China with ample foreign investors wanting to invest in them. This move could only be fueling the growth of asset bubbles (Zhou 79). Conclusively, a serious market bubble is looming in China if the government does not take effective measures to contain it. Since 2006, economists and analysts have predicted a large asset bubble and this has increased with time. Forsythe, Michael and Hamlin, Kevin. China’s Real Estate Bubble Causing Growing Concern.

Describe your Out of Class Experience Essay Example | Topics and Well Written Essays - 1000 words

Describe your Out of Class Experience - Essay Example school period is something not many people do normally and especially when the examinations are near and usually the norm is to be found strictly in reading zones. This was a new experience for me and also for the few friends I was with as i had never done anything like this as I am always busy in the libraries and engaging in group discussions just before an exam which builds up the pressure and tension making remembering harder. This was the exact opposite during this experience as I got to remember even without much reference to class notes and discussions. The insight I got from this whole experience was that education is possible anywhere as long as one puts their mind to what they are studying or being taught and is relaxed. It was during my summer holiday break last year, when i had an opportunity to experience another out of class experience by attend a seminar that is related to my course in school and that was being held near my home town. The seminar was a five days affair with five different motivational guest speakers most of whom were born in that town and had become successful in their careers. The aim of the seminar was to motivate and encourage the students pursuing this course and who are from my home town not to dwell on their backgrounds but think about the future and how they could change that whichever way they wanted. These were ideal speakers as they had experienced almost all the trials, tribulations and joys that are present in this town and hence the far they reached and whatever they had achieved by the time the seminar was being conducted was possible for the students residing in this location. This got me to start dreaming big about my future and how all the challenges I was currently facing in school and in life as a result of the geographical locations should not be a hindrance but act as a stepping stone towards a bright future. I even got one of the speakers to be my role model to help me in achieving this dream and

The Middle East, Byzantium, and East Asia Essay Example for Free

The Middle East, Byzantium, and East Asia Essay There were many similarities and differences between Byzantium and the Middle East and East Asia. Both regions were based on religions that were founded by prophets, but Byzantium and the Middle East had religions that were monotheistic, and East Asia did not. They also differed in the fact that the Middle East and Byzantium focused on academic development, and East Asia focused on military development, but were similar because both developed new ways to use projectile weapons. Both East Asia and the Middle East and Byzantium were similar in their use and development of projectile weapons. The Byzantine Empire developed a very powerful, projectile weapon called Greek fire. It was mainly used in naval warfare, and essentially could burn while floating on water for very extensive periods of time. This weapon was exclusive to the Byzantine people and has been lost with them. Gunpowder was also first developed in China. Gunpowder could be used to fuel the first guns, which while simple at the time, were deadly to the rest of the world. This idea spread through trade to the Islamic people, and later the rest of the world, transforming warfare for the rest of time. There were also differences in intellectual development between Byzantium and Mesopotamia and East Asia. For one, Byzantium was more academically advanced, while East Asia was more militarily advanced. The Byzantine Empire focused much attention on architecture. The people there build enormous, beautiful buildings. One of the most famous was the Hagia Sophia. Rome also had many writers who wrote great works of history and poems. East Asia on the other hand was more focused out military advancements. China created gun powder, which was a huge help in stopping nomadic invasions because of the distance cannons could blow. Also steel and iron weapons were made which were very strong. East Asia was also responsible for the creation of the printing press, which made it possible to produce text very quickly and in large amounts, helping communication immensely. There were similarities between the religions of Middle East, Byzantium, and East Asia. The religions in the Middle East, Byzantium, and East Asia, Islam, Orthodox Christianity, and Buddhism, respectively, were all religions that were started by prophets; Islam by Mohammed, Christianity by Jesus Christ, and Buddhism by Siddhartha Gautama. Islam spread very rapidly throughout the Middle East. Islam was the fastest spreading religion during this period. Similarly, Buddhism spread rapidly from its birthplace of India to East Asian countries such as China, Japan, and Korea. In the Middle East and Byzantium, the religions being practiced were strictly monotheistic. In East Asia, they were not. The dominant religion in the Middle East was Islam, a monotheistic faith revealed through the prophet Muhammad. In Byzantium, Christianity, another monotheistic religion, dominated the region. However, in East Asia, there was no monotheistic religion. Instead, the people in this area practiced Confucian traditions and Buddhist customs.

A Literature Review of Association Rules in Mining

A Literature Review of Association Rules in Mining Abstract Mining association rules is an essential job for information discovery. Past transaction data can be analyzed to discover client behaviors such that the superiority of business decision can be improved. The approach of mining association rules focuses on discovering large item sets, which are groups of items that come into view together in a sufficient number of dealings. Association rules are if/then statements that help uncover relationships between seemingly unrelated data in a information repository. In this paper we will show by experimental results the behavior of apriori algorithm. Weshall describes the basic concepts of association rules mining, the basic model of mining association rules. Finally, this paper describes the association rules mining and its techniques. Introduction Association rules mining is an important task in data mining. It is a popular and well researched method for discovering strong associations between variables in large databases. It is intended to discover strong rules between different variables in databases. A large amount of data can easily be analyzed to discover customer purchasing behavior which improve business behavior. The goal of the association rules mining is to identify items that are bought together by sufficiently many customers. The strong relation between different items in the market are existing like the peoples who buy milk also tends to buy bread and eggs in this sentence there is a relation between milk and bread. So association rules are used to identify these relationships between items for the improvement of business behavior. Association rules can be expressed as: R: X==>Y, where: X à ¢Ã…  Ã¢â‚¬Å¡ I, Y I, and X, it is said that if the item set X occurs in a transaction, then Y will inevitably appears in the transaction. Therefore, X is called a prerequisite for the rule; Y is the result of the rule. Support and Confidence are two different interestingness for measure. Support of an item I is the number of transactions that support (contains) I, and Confidence compares the number of times the pair was purchased to the number of times one of the items in the pair was purchased. In probability terms this is referred to as the conditional probability of the pair. For example, if a supermarket database has 100,000 point-of-sale transactions out of which 2,000 include both items A and B and 800 of these include item C, the association rule If A and B are purchased then the item C is also purchased on the same trip has a support of 800 transactions (alternatively 0.8% = 800/100,000) and a confidence of 40% (=800/2,000). A huge number of association rules can be identified if the database is large. So for minimizing association rules minimum Support and Confidence are considered, both are specified by the user which help us to and valuable rules from database. Association Rule Mining Algorithms A-priori Algorithm Principle of Apriori Algorithm: If an item set is frequent, then all of its subsets must also be frequent. Apriori algorithm is a classical and breadth first search association rules algorithm. This algorithm was first proposed by Agrawal et al in 1993.Apriori algorithm strategy is to separate association rule mining tasks into two steps: First discover frequent item sets, and the second is the Generating of Association rules, it extracts high confidence rules from the frequent item sets. The first step for mining frequent item sets the algorithm will produce a large number of Items; the algorithm will execute K iterations where K is the number of items in the second iteration the algorithm produce some frequent item sets with the first selected frequent item set. After the K iteration the algorithm produce the superset of all frequent items. Here the basic idea of generating frequent item sets is: First step, statistics the frequency of the set with an element, and identify those item sets that is not less than the minimum support, that is, the maximum one-dimensional item sets. Then start the cycle processing from the second step until no more maximum item sets generated. The cycle is: in the first step k, k-dimensional candidate is generated form (k-1) dimensional maximum item sets, and then scans the database to get the candidate item set support, and compare with the minimum support, k-dimensional maximum set is found. The apriori algorithm takes advantage of the fact that any subset of a frequent item set is also a frequent item set, therefore it reduce the number of candidates being considered by only exploring the item sets whose support count is greater than the minimum support count snf all infrequent item set can be pruned if it has an infrequent subsets. Apriorialgorithm is breadth-first algorithm, therefore if the database is too large then it suffer from a number of inefficiencies by creating a large number of subsets. Apriori algorithm uses sets intersections to determine support values. It determines the support values of all (K-1) candidates before counting the K candidates. The dataset may be too large thus the problem is that the resulted frequent item set may be exceeded with main memory and wasting of time to Figure 1: Apriori algorithm Pseudo code. Figure 2: Improved version of Apriori Algorithm Hold a large number of candidate set with much frequent item sets. So to overcome this problem the dataset is partitioned in different chunks and each chunk is treated independently. And then the resulted frequent items are merged with one extra scan. Applications: Basket data analysis, cross-marketing, catalog design, sale campaign analysis, Web log (click stream) analysis, and DNA sequence analysis. 2.1.1. Variation in Apriori Algorithm The limitation of appriori algorithm is improved by the improved version ofappriori algorithm. It is to be defined as: Suppose Ck is the candidate item set of size k, and Lk is the frequent item set of size k in the proposed approach the algorithm is improved by reduce the time consuming for candidates item set generation. Here the algorithm firstly scan all transactions to generate L1 which contains all items, and found their support and transaction ID, and then L1 is used as a helper to generate L2, L3.Lk, then generate C2 by joining L1 * L1 to construct 2-itemset C(x,y) where x,y are the items of C2. Before scanning all transaction records to count the support count of each candidate, use L1 to get the transaction IDs of the minimum support count between x and y, and thus scan for C2 only in these specific transactions. The same thing for C3, construct 3-itemset C (x, y, z), where x, y and z are the items of C3 and use L1 to get the transaction IDs of the minimum support count bet ween x, y and z, then scan for C3 only in these specific transactions and repeat these steps until no new frequent item sets are identified. FP-Growth Algorithm FP-growth algorithm is one of the latest and most efficient algorithms in depth-first algorithm. It allows frequent item sets discovery without candidates item set generation. It is a two step approaches, first build a compact data structure called FP-tree and then extract the frequent item sets directly from the FP-tree. Compared with Apriori Algorithm, FP-growth has the following advantages: To avoid multiple dataset scanning it scan only the dataset twice. It increases space and time efficiency. But its difficulty lies in large and sparse datasets, in the mining processing and recursive computations require considerable space. Applications: Basket data analysis, frequent patterns. Association Rules Applications 3.1. Market Based Data Analysis A typical and widely-used example of association rule mining is market basket analysis. It is a technique that discovers relationships between pairs of products purchased together. The technique can be used to identify the items having strong relationship. The idea behind market basket analysis is simple, simply examine the order of products have been purchased together. For example in market basket analysis the fact might be uncover that if a customer buy milkalso tends to buy breads. So using this information we might organize our store that milk and bread next to each other. For doing market basket analysis there is some couple of measures is used, which is frequency, minimum Support and minimum Confidence, frequency is the number of times two products were purchased together, and minimum Support and Confidence are discussed before. Market Basket Analysis print report about given items, for example if we need to find relationship of Milk with others Bread, Eggs and Cheeses, then market basket analysis print a reports. TheReport consists of the products name, Frequency, Support and Confidence. Market Basket Analysis: Milk Product Frequency Support Confidence Breeds 820 82% 91.1% Cheese 800 80% 23.5% Eggs 750 75% 34% The higher the confidence means that there is a probably of strong relationship between the products. In the above example confidence of Milk and Breads shows that in 91% of transactions Milk and Bread are sold together. 3.2 Customer Relationship Management (CRM) Customer Relationship Management is a combination of business process and technology that seeks to understand a companys customers from the perspective of who they are, what they do, and what they are like. Here we are focusing on the CRM of banking sector, which are focused to find the preference of different customer, to provide services to the customer to enhance cohision between customers and the bank. Association rules are used to identify customer preferences and customer behavior. Conclusion Association rules mining are a popular and well researched method for discovering strong associations between variables in large databases. In this paper we have describe Association rules mining which is the important task of data mining. Then we describes techniques for the Association rules which is apriori and FP-growth algorithm, the limitation of apriori algorithm was inefficiency in case of large database by checking all k-1 items, the improve apriorialgorithm overcome this problem by finding transactions ids of every frequent item and then for k+1 set generation used that k-1 table and search only those transactions in which the current item are exist. According to this the efficiency of the algorithm is improved. Then we discuss FP-growth algorithm which is depth first search and fastest algorithm, it uses tree to find frequent item sets. In the last the application of association rules Market basket data analysis and Customer Relationship management are discussed in this pa per.
