As We Advanced From The 20Th Century To The 21St Century

As we advanced from the 20th century to the 21st century many of our ideas, outlooks, and information we knew about the world changed and progressed greatly. This is also true for how we as a civilization viewed management, progressed and continued to progress in bettering our management practices. This book analyzes old and new assumptions of management practices along with the reality that comes with the new strategies. The author also describes that as we go through these changes a leader that knows how to work with change is important to have to get passed the many information challenges. Drucker then describes that as the organizations change it is important that individuals within the organization also change to help reach maximum†¦show more content†¦Since the discipline behind management is always changing so are the assumptions that come with it. Drucker First lists 7 old assumptions of management, which are: 1. Management Is Business Management 2. There is – or there must be- one right organization structure. 3. There is – or there must be- one right way to manage people. 4. Technologies, markets and end-users are given 5. Management’s scope is legally defined. 6. Management is internally focused. 7. The economy as defined by national boundaries is the ecology of enterprise and management. Ducker goes on to explain that the first three assumptions are related to the discipline of management while the last 4 are related to the practice of management itself. He also points out that these assumptions might have been helpful back then but are actually hurting us now. They are now so far removed from actual reality that they are becoming obstacles to the Theory and even more serious obstacles to the Practice of Management. Indeed, reality is fast becoming the very opposite of what these assumptions claim it to be (Drucker). Drucker then goes on to explain his 8 new management assumptions related to the discipline of management, which are: 1. Management is not only for profit-making businesses. 2. There is not only one right organization. 3. There is not one right way to manage people. 4.

Miriam Webster defines Prejudice as â€Å"injury or damage resulting from some judgment or action of another in disregard to one’s rights†. Although most people tend to associate prejudice with racism, that is not always the case.

The Narrator also feels he has an inherent superiority to Robert because of this , placing a self-centered twist onto everything. For all of the Narrators prejudice towards others, he is more than happy to not place any of his critical and judgemental focus on himself. It is shown in glimpses of the story how the Narrator dictates his world by only what he can actually see, placing a limitation on himself that Robert does not have. â€Å"It was beyond my understanding. Hearing this, I felt sorry for the blind man for a little bit. And then I found myself thinking what a pitiful life this woman must have led† (139). The Narrator lacks what can be perceived as a sight into both his own, and others, emotions. It is further on that we come to realize how much the Narrator relies on his vision, thinking that Robert’s wife, Beulah, could have worn anything she wanted to, not because she felt like it, but because no one could appreciate how she beautiful or ugly she looks.

Political Forum Post

Question: What, if anything, do the current conflicts between Russia and Ukraine, and among the Shi'a and Sunnis in Iraq and Syria, say about the utility of Huntington's thesis about the clash of civilizations? Answer: At the end of the cold war, the expertise of international relations and the political scientists were discovering the predictable and probable situations after this devastating revolution. The conflict between Russia and Ukraine took place due to some important reasons. The conflict arose when the presidents of Ukraine refuse to make an economic deal with Russia regarding the agreement in association. After a few days, that particular individual agreed to accept another economic deal with Russia. This was one of the effective reasons to for the conflict of Russia and Ukraine. On the other hand, Russia chose Ukraine for making their economic deal because Ukraine is possessed with the products of high quality along with its low prices. As a result, Russia would be benefited to make a free agreement with Ukraine. The primary reason between the conflict of Shias and Sunnis was differentiation of their values, beliefs and ethics. As per the Muslim theology, God renders the blessing through the prophets who plays the role of messengers[1] . Shias do not prefer to believe on messengers as they believe to reach the god directly[2]. As per their point of view, human being does not need to go through the prophet in order to receive the blessings of god. The beliefs and values of Sunnis were just the opposite. That was the root of arising conflict between Shias and Sunnis. This has become the ancient religious divide made a conflict regarding transforming a map for the people of Middle East. The current scenario has been changed right now. At present, more than ten thousands militants have been spread throughout Iraq and Syria. It was the amalgamation both Shias and Sunnis. The primary concern of many expertises was reducing the violence between them. Still, it is a matter of argument whether the religious conflict between this Shia and Sunnis would be reduced or it would go to the ultimate violence that would become a severe threat for leading a life successfully or for maintaining peace in the international field. In this situation, the well-known political scientist Samuel Huntington described the future aspect of the international system and policies[3]. Samuel believed the fact that one particular region is possessed with various cultural divisions such as Western, Islamic and Hindu and so many. Each and every cultured is attached with their own perception and values. As per his point of view, Islamic civilization had been raised as one of the major troubles. The inhabitants of Arab do not intend to share their values and perception with the Western countries. As a result, a major communication gap has occurred in between them. The nature of the conflict: The post situation of the cold war, the political scenario was it was entering to the new age of revolution. The nation states were getting back their rivalries, that was maintained traditionally and the aspect of tribalism and globalism was supplying the strength to the decline of the nation. As these aspects were the matter of main concern of the era, they missed the central aspect of the globally inspired politics. The aspect of civilization after the cold war: The migration to the Western Europe was incredibly increased by the growth of population in the Arabian countries. The aspect of racism was broadly open that time. The clash of civilization was indicated by the differences between the Islam and the west culture. The conflict was increasing on the area of northern border in Islam, which involves the Orthodox and Muslim people, which expressed as the violence between the Serb and Albanian, and the relationship was also getting destroyed between the Bulgarian and the minorities of the Turkish[4]. Conclusion: It was not that much surprising, as people were so much excited for the after effects of the cold war, the thesis of Huntington was a little bit controversial. The facts of civilization was globally criticized by the critics, as it consists of the unclear definition of the concept of civilization, as the western civilization is mainly consists of the western and modern, i.e. non-western civilization.

learning and motivation Essay Example

learning and motivation Essay Introduction: In order to study how people learn a new set of behaviors, we are going to apply three learning theories which learned though this course: classical conditioning, operant conditioning and social cognitive theory . ln this paper, only one example would be applied by the theories. The chosen example is a commercial of LNYX body wash which will be further described in the next paragraph. First, we will briefly describe the cases. Then, the application of the theory will be presented part by part from classical conditioning, operant conditioning to social cognitive theory . n each art, we will briefly introduce the major concept of the theories used , followed by the studies on the effectiveness of the commercial. Commercial Content: http://www. youtube. com/watch? v=YuvIsaOYr18 The following is the description of the commercial content. The commercial showed that there are two men who were using two different kinds of body wash product. They went clubbing together after us ing the two different body wash products. The man who used LYNX body wash is charm and handsome so that he got many attractions from girls but another man who used other brand of body wash did not. Classical Conditioning: According to the learning behaviorism approaches, there are two forms of associative learning: Classical conditioning and operant conditioning. I would briefly introduce what is classical conditioning and apply classical conditioning in the chosen advertisement. Last but not least, it will be an analysis on the effectiveness of this advertisement with certain related concepts. Classical conditioning is learning through association/ pairing This is a basic form of learning in which one stimulus predicts the occurrence of another. It also involves making a new connection, or association, between events in the environment. Referring to the commercial showed, before conditioning, charming and handsome man was the unconditioned stimulus and naturally elicits to the reflex of the unconditioned response which was got attraction from girls. During conditioning, there was the pairing up between an unconditioned stimulus and a neutral stimulus. Refer to the commercial, charming and handsome man was the unconditioned stimulus and the LYNX body wash was the neutral stimulus which has no intrinsic meaning to the organism before conditioning. After conditioning, man would get attraction form girls after using the LYNX body wash product.

According to the related concept of classical conditioning, stimulus generalization is automatic extension of conditioned responding to similar stimuli. Thus, One who are confused about LYNX body wash with other similar product cannot identify the difference and response in the same way with the similar products. That is, they believed that using other brands body wash can also get attraction form girls. Then, the commercials effectiveness would be diminished. Under another situation, stimulus discrimination, the organism does not respond the same way to two similar stimuli as it has learned to distinguish between them. One can distinguish between products of different brands and distinguish that only the use of LYNX can attract girls. So, the effectiveness of the commercial increase as people are willing to buy LYNX body wash in order to get attraction from girls . Therefore, the commercial effectiveness depends on peoples cognition on this advertisement. Operant Conditioning: According to operant conditioning, learning in which the probability of a response is changed by a change in its consequences. (Skinner, 1983)Following the law of effect, if the consequence is positive, or satisfying to the organism, in future with the same stimulus presented again, the same response will be more likely to occur, vice versa. Thus, Skinner said that we learn an association between a response to a stimulus and its consequences with the experiment he did. In this commercial, the stimulus is the use of LYNX body wash; the consequence is become attractive among girls. As we ll know, the consequences attractive here, is positive and pleasant, so people will be more likely to use LYNX body wash. The video shows both types of consequences: reinforcement and punishment. In the video, the man who use LYNX body wash and go clubbing becomes more charming and attracts girls attentions. Being charm is a positive reinforcement. Since Behavior is followed by the delivery of an appetitive stimulus, and it is Increases the probability of that behavior (Skinner, 1969), the delivery of attractiveness after using LYNX body wash reinforces him to increase the behavior of using LYNX body wash. Another man in the commercial, who wears in pink, is using other common brands body wash and going clubbing, he becomes feminine and unwelcome among girls. Removal of attractiveness is the negative punishment since behavior is followed by the removal of an appetitive stimulus, and it is decreasing the probability of that behavior (Skinner, 1969). Therefore, people will not choose to use other brands body wash so as to avoid the unwelcome consequence of removing attractiveness. In order to have an in-depth study on the effectiveness of the commercial based one perant conditioning, we will examine the fulfillment of some important conditions immediately and reinforcer must follow the response. In the commercial popularity among girls (reinforcer) Just followed the response of using LYNX body wash immediately. That means Reinforcers that precede a response rarely have an effect on the response. Moreover, there is no delay in the presentation of popularity among girls after the men using LYNX body wash which preserve the effectiveness of commercial. If the presentation of popularity among girls delayed, the commercial would become less effective as the reinforcers presentation is elayed and the noticed consequence become less rewarding. Last but not least, there are two men using in different brand of body wash but the popularity among girls was only presented when the desired response (use LYNX body wash) occurred. This fulfills the reinforcement contingency which stated that the reinforcer should be presented only when the desired response has occurred. Since there is a strong fulfillment of those conditions for operant conditioning, the commercial is regarded as effective. Social Cognitive Theory: The social cognitive theory force on what and how people learn from one another. There is a reciprocal causation in social cognitive theory stated that the interaction of three variables: environment, person and behavior, affect each other. In order to have a clearer insight on how social cognitive theory is applied in this commercial, we initiate our application from the first step, that is, processes in observation learning. The processes of observation learning included Attention to appropriate models, Retention, Motor Reproduction and Motivation. That means the learner have to pay attention to character in the commercial and remember what the character did. Next, he has to practice Models behavior by using LYNX body wash. If he believe that he will be charming after using LYNX body wash, he will be motivate to keep imitating the Models behavior. Observational learning occurs when an organisms responses are influenced by the observation of a models behavior. Unlike other learning theories, observational learning can be vicarious. In another words, organism simply observes another perform a behavior, notes the consequences, and modifies its own behavior in a future, similar situation. In such, learner observes that the models behavior of using LYNX body wash so as the vicarious reinforcement the model received in the commercial. The learner would then be reinforced by the vicarious reinforcement of Charming and handsome, he would be more likely to imitate the models behavior for the sake of obtaining the same kind of reinforcement in the future. That means, he is going to use LYNX body wash so as to become charming, handsome and attractive to girls. oth self-efficacy and expectancies would affect ones likelihood in imitating the behavior. When one believes they are capable of executing the behaviors successfully, he is with high self-efficacy. Thus, one who got high self-efficacy think that it is easy to get and use LYNX body wash after watching such modeling. He is more likely to imitate the model and using t he product mentioned in the commercial. Expectancies, is about the consequences of a behavior are what render the behavior more or less likely to occur. When one expect to receive a favorable consequence of being Charm and handsome after using LYNX, he is more likely to do so. In order to study whether the commercial is effective, we examine the fulfillment of characteristics of effective models. We found that the model is competent because earners are capable in getting get LYNX body wash. The model behaves in stereotypical gender-appropriate ways as boys generally want to be attractive among girls. to our belief, the commercial will be more effective to boys who seeking for lovers because the models behavior is relevant to the observers situation. as the commercial fulfill such characteristics of effective models, it is an effective commercial form the analysis of social cognitive theory. Conclusion: In conclusion, we had applied all three theories namely classical conditioning, operant conditioning and social cognitive theory in one commercial. We found that the learning effectiveness of the case would depend on different conditions. For instance, in classical conditioning, people would have confusion with different body wash brand thus decrease the effectiveness of the commercial when there is a stimulus generalization; however, commercial would become more effective when there is stimulus discrimination because people could distinguish between different brands which urging them in purchase LYNX body wash. In addition, we can look into some particular conditions and characteristics to scrutinize the effectiveness of the commercial. For operant conditioning, we have examine on some important conditions for operant conditioning like the reinforcement contingency, reinforce must follow the response and immediacy. For social cognitive theory, we have study in some of the Characteristics of effective models: Such as competency, stereotypical gender-appropriate ways and whether the models behavior is relevant to the observers situation. We also noticed that one with high self-efficacy and expectation towards the behavior would also increase the effectiveness of the commercial. Based on the fulfillment of those particular onditions and characteristics of operant conditioning and social cognitive theory respectively, we reckon that the commercial is still regarded as the effective one.
