Political Leadership and Organization

Introduction Leadership is a vital component in every society. It defines the values, goals, and objectives of people in the society. Effective leadership not only defines these elements, but also determines how they are achieved. The success of the political leadership and organization emanate from the leadership style of the leader.Advertising We will write a custom research paper sample on Political Leadership and Organization specifically for you for only $16.05 $11/page Learn More Therefore, to ensure success of political leadership, it is important to work with good leaders who are focused on positive results. Good leadership depends on the leader’s individual qualities or character (Crick 23). Based on these assertions, this study will take a comparative stance by analyzing the good leaders, in particular Bill Clinton and John Kennedy. The characteristics of a bad leader will also be examined. In this comparison, the study will compare the New York Mayor Mr. Michael Bloomberg and the Toronto Mayor Mr. Rob Ford. Hypothesis Political leadership and organization require the leader to exhibit exemplary characters of charisma, good interpersonal skills, results orientation and good problem solving skills (Wren 132). The personal qualities of a potential leader determine the outcome for the whole nation, so superior intelligence and education are a must. It is crucial that the person is respectable, reliable and just. Since the market and economy greatly influence the outcome of the leader’s plans and goals it is their direct responsibility to predict any fluctuations and prevent loss of stability and control. This study will look at the relationship between a leader’s character and the success of the leadership style. Empirical/ Theoretical gap Political leadership and organization are among the most interesting topics that have attracted attention of various researchers and authors. Every leader faces a theo retical gap in relation to the practical control and functioning of a nation, and the knowledge or empirical understanding that was gained prior to becoming a member of the office. When an individual starts running for presidency or other leadership position, they will mobilize the resources and the political processes that are necessary for taking charge. Often, the internal politics are not as clear cut before the person gets the position in the government. As such, they must become aware of the current matters regarding the economy and policies that need to be changed or added.Advertising Looking for research paper on political sciences?

Sometimes, before the leader is selected, a candidate will make promises that sound fair, but the reality is somewhat skewed, as many d etails are still unknown. As a result, the gap between theory and practice gets overlooked. This leads to promises that are broken, and a change in policies that was over optimistic beforehand. This is why foresight and empirical knowledge should be balanced with practice. Mr. Bill Clinton William Jefferson Blythe III (Bill Clinton) was one of the youngest presidents in America. The leader was elected to the office of the president as the 42nd president of the United States of America. Bill Clinton was also among the first Democratic presidents who managed to serve two terms in the office. Clinton attended Edmund Walsh School and Georgetown University where he graduated with a Bachelor of Science degree (Morris 100). There are several factors that make Bill Clinton a good leader who has ever ruled the U.S. Apart from being a charismatic and influential individual, the leader is mainly remembered for significant contributions to the development of the country. Contribution Bill Clint on was of one of the American presidents who managed to reduce the deficits in the federal budget and the economic recovery. The economic team appointed by the president played an important role in reducing the government expenditure and proper use of public resources. On the political front, Clinton facilitated the change process in the Democratic Party by ensuring that the party was open to many Americans from various dimensions of social life. The leader changed the party to accommodate the needs of minorities and other groups in the country. During Clinton’s reign, the Democratic Party played an important role in protecting the disadvantaged groups and stimulated economic development through government initiatives (Morris 112).Advertising We will write a custom research paper sample on Political Leadership and Organization specifically for you for only $16.05 $11/page Learn More Before his life in politics, Bill Clinton served in various lead ership capacities. This therefore indicates that Clinton was born with leadership qualities. He became the student leader of Georgetown University and was also the leader of the music band in college. Clinton was also involved in humanitarian initiatives displaying his leadership skills which made him an effective member. For instance, his reforms in the health sector were aimed at improving accessibility and quality of health care. He received higher ratings from the members of the public due to his charisma and concerted efforts to fight the spread of HIV/AIDS, as well as environmental problems such as global warming. Mr. John Kennedy John Fitzgerald Kennedy was the 35th President of the United States of America. His accession to power was marked by contention when he narrowly defeated the Republican candidate Mr. Richard Nixon. He served from 1961 to 1963 when he was assassinated during a public rally. Prior to his political career, John Kennedy was a leader in various capacities especially in the military. His participation in the navy earned him recognition and awards for exemplary service. John Kennedy was a brilliant naval officer who is remembered for successfully leading his combat in Panama. In the navy, he rose to the ranks of a lieutenant and was in charge of a patrol board that toured the Pacific theater. Kennedy became a hero in the military sector when he saved the lives of his fellow naval officers when their boat capsized (Alford Newman 49). Contribution Comparing the achievement of the two leaders it is evident that John Kennedy’s achievements delved on a diverse range of issues in America. Clinton’s main achievement was based on economic improvement through reduced federal deficits. He also improved the education sector through adoption and enactment of various policies. John Kennedy on the other hand had achieved that touched on various aspects of life (Crick 110). Most Americans believe that John Kennedy was one of the most successful presidents that ever ruled America. It was during his reign that America managed to land on the moon. It was also through John Kennedy that America was able to overcome the invasion of Cuba and the Soviet Union.Advertising Looking for research paper on political sciences? Let's see if we can help you! Get your first paper with 15% OFF Learn More The president also played an important role in ending racial segregation in various transport facilities and social institutions such as schools. Kennedy’s initiative to establish the Peace Corps program placed him in a position of great leaders. These achievements therefore tend to surpass the achievements that were attained by President Bill Clinton (Wren 121). Mr. Michael Bloomberg Mr. Michael Bloomberg is the one of the longest serving mayors of New York. Elected in the year 2001, Mr. Bloomberg greatly contributed to the development of the city in various aspects. He started his career at Salmon Brothers. However, he was laid off when the company was sold to another organization. After retrenchment, Mr. Bloomberg started his own company that offered business information and data management services to other organizations in New York (Bloomberg 23). Mr. Michael Bloomberg resigned from Bloomberg L.P. and joined politics in the year 2000. He decamped from the Democratic Part y to contest for the mayoral post on a Republican ticket. Contribution The mayor played an important role in transforming New York after the attacks of 2001. When he resumed office in the year 2001, the mayor introduced different policies that enhanced the performance of various sectors. For instance, in the year 2002, graduation from high school increased by more than 26%, crime rate decreased by 35%, and welfare rolls declined by more than 22%. The mayor also played an important role in reducing other social problems such teen smoking and alcohol abuse among the youths. Mr. Bloomberg was one of the mayors of New York who facilitated economic growth and the creation of new job opportunities for the youths (Crick 76). One of the key achievements that enabled the mayor to earn higher ratings from the public was his concerted effort to transform the education system. Bloomberg introduced new education policies, which improved the quality of education and rate of enrollment. Bloomberg is one of the most philanthropic individuals in the U.S. The mayor has participated in several charity programs, and has donated his time and resources to various community based initiatives. Before politics, Mr. Michael Bloomberg was a great business leader in various organizations. He led the financial and equity department of Salmon Brothers and later became the chief executive officer and chairman of Bloomberg P.L (Bloomberg 23). Mr. Rob Ford Robert Bruce Ford joined politics in the year 2000 when he was elected the councilor to represent Etobicoke Ward in Toronto. Ford was first elected to the mayoral seat in the year 2010. Mr. Rob Ford has been overwhelmed by his personal escapades, which have greatly comprised his leadership qualities. Mr. Rob Ford has been accused of mismanaging public funds, conflict of interests, and drug abuse (Goddard 2011). Before Rob Ford rose in politics, he had served in various leadership positions, especially in the business sector. The mayor had s erved as the director of the Ford Family Company before he was elected to mayoral positions (Wren 210). As such, even though he had experience as leader, and accomplished some changes for the city, his personal life became too detrimental to the office. Every leader must realize that they are constantly watched by the public, and their professionalism in public life and governmental positions must be aided by their personal life. Contribution As a leader, Ford has played an important role in ensuring that Toronto remains one of the safest cities with free health care programs. However, his critics believe that he has contributed to the collapse of the city council in Toronto. Mr. Ford has been blamed for mismanagement of funds. Compared to the New York Mayor, Mr. Ford was not focused on development, and did not implement change to policies and administration. Benefits of Comparison From the comparison of the various leaders discussed in this study, it is evident that leadership tran scends from the character of the individual. Comparison of political leaders also reveals how various leaders affect the growth and development in the society. From the comparison of Bill Clinton and John Kennedy it is evident that Clinton introduced economic policies, which transformed the federal budgeting and expenditure. Kennedy, on the other hand, played an important role in protecting the country against foreign invasion. Comparison of various leaders is important in expanding the knowledge on the topic of leadership and organization. It is also used in learning the various leadership styles that are used by the leaders (Creswell 189). Methodology and Data The research method employed in this study was qualitative. The researcher mainly relied on secondary and primary sources of data which provided reliable information on the topic. The researcher collected data by interviewing respondents who worked in government offices and other social institutions such as schools (Creswell 240). The researcher visited the respondents in the areas and managed to collect data by accessing relevant materials on the topic. To get information about the two mayors the researcher interviewed the city council officials from New York and Toronto. Results The researcher used a population sample of 25 respondents who were interviewed from various government offices and the city council departments. The following elements were considered for evaluation of leadership qualities. Leadership attributes Score (Good) Score (Bad) Good management skills 72% 28% Good Interpersonal skills 90% 10% Development Oriented 81% 19% Control over personal matters 70% 30% From the above table, good or great leaders scored higher marks on the above mentioned attributes. For instance, the respondents believed that all the leaders from Bill Clinton, John Kennedy, Michael Bloomberg, and, Rob Ford had good management skills. The other important element was the control over personal issues. The respondents believed that a good leader should have control over their private life. Uncertainty surrounding the results mainly emanate from the lack of accuracy of the information provided by the respondents during the interview. Everybody’s view is rather subjective, and might be based on understanding and information from other people. As such, only practical results can be properly evaluated. Conclusion Political organization and leadership are important areas of study which enable individuals to learn how organizations and regions are governed. Good leadership contributes to the development and growth of a given region in various aspects. However, the success of a leader depends on the leader’s personal characters and the leadership style used in influencing issues, such as management of public resources and other important political and economic matters of the nation. Shortcomings The short comings associated with this study mainly stemmed from the research method employed by the researcher and respondents who were interviewed. Also, situational or environmental factors must be taken into consideration, as the difference between pre-election times might be greater when compared to the leader who has already been elected. It is critical to base theory and practice on realistic conditions and empirical knowledge. Normative Implications Political leaders should uphold responsibility for issues that affect the society, and ensure individual discipline in the public domain. The amount of work that the leader has is a lot for one individual, so uniting the efforts in the fight for common goal must also be present. Considering all the qualities of a leader it is possible to see that the disadvantages must be minimal, if not non-existent at all. The leader can focus all attention on promoting policies and regulations that are promised to the people, leaving the minor organization and support to the party members. Personal life is closely conne cted to the position of the leader, so it must be kept proper and respectful. Works Cited Alford, Mimi Newman, Judith.

Analyse Conan Doyles The Hound of the Baskervilles Essay Example

Analyse Conan Doyles The Hound of the Baskervilles Essay Example Analyse Conan Doyles The Hound of the Baskervilles Paper Analyse Conan Doyles The Hound of the Baskervilles Paper Essay Topic: The Hound of the Baskervilles Analyse Conan Doyles The Hound of the Baskervilles exploring how the author uses the devices of detective fiction within the novel to create suspense and mystery. Sir Arthur Conan Doyle is one of the most famous writers of detective fiction and the creator of the brilliant characters Sherlock Holmes and his right-hand man Dr. Watson, Sherlock Homes being one of the best known detectives. Conan Doyle, the son of a civil servant was born in Edinburgh in 1859. Later he studied for his degree in medicine and then in 1885 after graduating he decided to set up as a doctor. In order to fill in quiet moments at work he decided to write detective stories. A Study in Scarlet which appeared in1887, introduced the detective Sherlock Holmes, whose appearances in several other stories made him and his character household names. Conan Doyles use of complex and ingenious plots, keeps the reader interested and creates suspense and mystery, which suggests that Conan Doyle may be responsible for some features of the detective fiction genre. The way in which Conan Doyle portrays Sherlock Holmes as being an arrogant man with a high intellect who uses his own deductive methods and elementary approach, also suggests that Conan Doyle may be responsible for some features of the genre. The book The Hound of the Baskervilles (THOTB) was published in 1902 which is reflected in the novel as we get a wonderful sense of late Victorian England. A point which we must not forget is that THOTB is based upon the legend of the hell hound in Black Shuck, on the North Norfolk coast. According to the legend the hell hound roamed the coast of North Norfolk and scared people to death. However Conan Doyle moved the setting of his novel THOTB to Devonshire so that he could create the story of THOTB. He may have also thought that Devons desolate moorland, could make the novel more exciting and create a greater sense of suspense and mystery for the reader. To find out how Conan Doyle uses the devices of detective fiction to create suspense and mystery in THOTB, it is necessary to examine THOTB to see whether he uses the devices of detective fiction and to what extent he uses them. One of the main features of the detective fiction genre is the use of the device of in media res, meaning in the middle of things. This is evident in the novel from the start. Generally most stories of the genre start in the middle of the action. This is when the crime has already been committed and it is just a question of who dunnit? . THOTB is introduced in this way when Dr. Mortimer goes to Sherlock Holmes and Dr. Watson with the case of the mysterious death of Sir Charles Baskerville outside his Devonshire home of Baskerville Hall. The reason why Dr. Mortimer comes to Sherlock Holmes with the case, is because he was a close friend of Sir Charles and he wants the mystery to be solved before the heir to the hall Sir Henry arrives from America. Firstly Dr. Mortimer reads a document to Sherlock Holmes about .. The origin of the hound of the Baskervilles. According to the legend the family has been cursed by a foul thing, a great, black beast, shaped like a hound, ever since the evil great ancestor Sir Hugo Baskerville had occupied the hall. The legend states that he was a malicious, greedy man who treated people very badly and then one night he crossed the moor chasing a maiden, but instead he was viscously murdered by a hound. Ever since then all the Baskervilles have been cursed and die in mysterious ways.

Impact National Culture on Leadership Traits and Behaviors Essay

Impact National Culture on Leadership Traits and Behaviors - Essay Example The following are the leadership traits and behaviors that may negatively impact organizational effectiveness in multinational companies: dictatorial, non-cooperative, non-explicit, irritable, egocentric, cruel/ruthless and loner. A dictatorial leader imposes strict commands and orders without leaving any space for dialogue or understanding (Hofstede, 2011). A non-cooperative leader is one who does not show elements of teamwork or support in the company activities. A non-explicit leader is not open but prefers carrying out his or her roles confidentially (Hofstede, 2011). He or she prefers when everything is kept back from the rest of the members, especially subordinates. Irritable leaders are short-tempered and are associated with recurrent instances of disputes and unreasonable ways of thinking. According to Hofstede (2011), egocentric leaders are careless of the feelings of others and are associated with self-centered and insensitive decisions, which leave other people socially hu rt and distressed. Cruel/ruthless leaders are unpleasant and unkind management groups who lead others mercilessly and at times brutally. A loner is a leader who prefers being secluded from the rest of the members. Additionally, loners mostly fail to associate with others (Hofstede, 2011). Yes, I believe that multinational managers must understand the subordinate expectations in order to lead effectively. Subordinate expectations are â€Å"expectations regarding what leaders â€Å"should† do and what they may or may not do† (Cullen & Parboteeah (2014, p. 663). Therefore, understanding subordinate expectations help in delivering exactly what is required in a multinational company. For a country with high power distance, I would recommend an autocratic leadership. High power distance countries are associated with dominant individualism and human rights.  Ã‚  

Sandro Botticelli biography Essay Example | Topics and Well Written Essays - 1000 words

Sandro Botticelli biography - Essay Example This can be seen in his first commission 'Fortitude' (1470), painted for the Merchants Guild in Florence. Despite this description of his painting style, he nevertheless produced strong images with an excellent attention to detail and good use of perspective though unlike many of that time he did not really concern himself with working out the exact details of either perspective or anatomy for that matter. This indifference with anatomy is one of the ways in which Bottacelli manages to produce the serene quality in many of figures in his paintings. Through the influence of Verocchio and the brothers Pollajuoli this idealism was combined with the naturalness of Masaccio. These qualities explain Botticelli's great influence over later painters. Botticelli's life was a retired one passed largely in very modest circumstances. We know, however that he was in the employ of the Medici and other prominent Florentine families from about 1483 to 1500. Although never inclined to frivolity he was yet influence by the worldly spirit of the age until Savonarola's powerful call to repentance aroused his moral nature and guided his powers, it now seems, into entirely new paths. He never knew how to take care of money and he died at last in need. Botticelli was too unassuming to sign and date his works in most instances, so that the order in time of his paintings has to be judged from the canvasses themselves. In 1470 Sandro started own workshop. Five years later, he painted the portrait (National Gallery, Washington) of Giuliano de' Medici, b rother of Lorenzo. In about 1478, Sandro, now in the favor of the Medici family, painted the enigmatic "Primavera (Spring)" (Uffizi, Florence). The work was commissioned by Lorenzo, son of Pierfrancesco de' Medici, a tormented and neurotic young man. The painting of "Primavera"- like "La Nascita di Venere (The Birth of Venus)" - was placed inside the Villa di Castello where Lorenzino lived. From this painting, a number of art historians have derived the iconography of the Florentine culture of Botticelli's day. Agnolo Poliziano, poet and tutor of Lorenzo de' Medici's sons (including Giovanni, future Pope Clemente X), with his lyric poems in which the wind teases nymphs in Arcadian woods, would appear to be the textual reference for Botticelli's mythology (Vasari 44). Other famous works by Botticelli include "Pallas and the Centaur", "Venus and Mars", and "The Birth of Venus". The figures certainly do not enact a known myth but rather are used allegorically to illustrate various aspe cts of love: in "Pallas," the subjugation of male lust by female chastity; in "Venus and Mars," a celebration of woman's calm triumph after man's sexual exhaustion; and in "The Birth of Venus," the birth of love in the world (Levey 103, 111). Whilst working for the Medici certainly conferred many rewards they were nevertheless a dangerous family to be round. The Renaissance, however, is not called that for nothing and along side the wars, killings and double dealings that punctuated that period was a real sense of a rebirth of ideas, science, art and philosophical thought. Key to this in Florence was the rediscovery of the philosophy of Plato, Aristotle, and Pythagoras, which fused together with some elements of eastern mysticism. This new philosophical ideal became known as Neoplatonism, which saw love, beauty,

Robots in Society and the Future

Robots in Society and the Future It is a very true slogan from Adidas brand, Nothing is Impossible. Humans abilities are limited, and that is why robots are created. Have you ever imagine that, when you wake up in the morning, once you open up your eyes, everything that is in your mind such as breakfast, office wear, slippers and even more have already being prepared by your robot-slave. You do not have to do anything; all you have to do is, sit and wait! You just have to sit on your bed and wait for your robot to serve you, arent your life will be easier and wonderful? From this, we can see that how amazing it could be with the existence of robots. May be in the future, they are only our trusted friends. The unstoppable improvements of modern technologies, in the same line, robots are introduced into various fields to assist the humans reckless abilities to improve their live. They have been widely used in industrial sector and also for personal use. The creation of robots is not only to assist us, but they give us good opportunities to be our substitute for exploration and experiment the new risky things that human had never dare to try but hunger to achieve. Our purpose of this report is to find out the kinds of robots that have been introduced into our life and the future robots. Our objectives are to find out: What are robots? Why do they exist? How do robots exist? What can they do? How far they can do? What are the side effects for human if they are over-populated? What is in humans expectation on future robots? 2.0 Findings and Discussion 2.1 What are robots? 2.1.1 Brief History of Robot When we said robots, we all feel that it was just only been made in this modern era. Actually the first creation of robot has been made centuries ago. The famous Leonardo da Vinci is also among all the creators who are involve in the creation and innovation of robots. The basic principles that motivate people to create the robots are to bring the advantages to mankind. First of all, the creations of robot begin with simple concept, with look like human, and then it can move. Through the evolution in times, the robots now are involving, now it can walk, talk, and behave like humans. The improvement of robots will never end, but now we can start to imagine how far robots will become in future. 2.1.2 Concept of Robot Isaac Asimov (January 2, 1920 April 6, 1992)Generally, in all humans thoughts, robots are human-like machines that have heads and limbs, move and talk like human, either with or without their own thoughts and can be fully automatic, or partially otherwise completely controlled by human. However in the world of reality, the basic concept of a robot is: a machine which is programmed to move and perform multitude tasks automatically, or may be partially controlled by human. It does not mean that robots must be built mimic to human, in fact they can be in any forms and shapes with different appearances as long as they meet the basic concept. According to a popular science fiction author, Isaac Asimov [1], he came out with 3 basic laws for robots, which they called it call Asimovs Three Laws of Robotics: Robots must never harm human beings. Robots must follow instructions from human without violating rule 1. Robots must protect themselves without violating the other rules. 2.1.3 Classification of Robots With the indefinite intelligence of human, robots have been invented in different kinds and ways, performing myriad tasks and jobs. The following are the basic classifications [2] for different robots: Tele-robots Tele-robots are robots that need to be direct operated by human beings through remote control sytem. The best example will be the toy robots for kids, where these entertainment robots are needed to be guided by human to move, turn, or carry out tasks. Telepresence Robots The manipulations for telepresence robots are much similar to the Tele-robots above. The different is that telepresence robots will send back video, sound and other data to make the operator to feel more like they are in the robots. These robots are suitable to be used in exploration field, especially when the targeted exploration area is not accessible for human. Static Robots They are robots which are not movable from places to places. They are fixed permanently on one physical location to perform their tasks using only a part of their movable components. Static robots have been widely used, such as robotic arms, in factories and laboratories to handle hazardous materials and chemicals. In Malaysia, static robots or robotic arms can be seen in car manufacturing factories. Mobile/Autonomous Robots These robots navigate and perform their chores and duties without the intervention of human. They have been created to have high intelligence to deal with any environments such as on land, sky and even underwater. These robots are normally wheeled, or with wings, propeller and etc, depending on their uses. Aerial mobile robots are referred to Unmanned Aerial Vehicles (UAVs) which have been used by countries with advanced technologies for military purposes. For underwater mobile robots, they are usually called Autonomous Underwater Vehicles (AUVs) and are used in sea exploration, military and commercial purposes. Androids Androids, which can also being called as Humanoid Robots, are being built to mimic human. They will have basic structures of human including head, body, hands and legs. Some of them have been installed with devices to produce sound or talk like human. 2.2 Why do they exist? As we all know, humans abilities are limited. Thus, we need something to fulfil our incompleteness and we have chosen the robots to do that for us. This can be clearly described when we use robots to carry and move heavy objects in our daily life. Land mine detectorOr, in the condition that risky jobs involve which may sacrifice the priceless life of human being, it will be wise to use robots as to replace the jobs for us to avoid any unnecessary sacrificing. Exploration for mines, space and underwater are example of highly dangerous tasks and these places are almost impossible for human to access. Sacrificing robots which can be valued in money is a much more intelligent act instead of sending the humans priceless souls to the path of death. In addition, assistance from robots arms for handling hazardous and acidic chemicals can also be widely used in laboratories to take the place of humans arms. Autonomous robot cleanerAnother main reason for the existence of robots is because of the demand of human to enjoy ease and comfort in their life. Everyone in this world is demanding to live in the best and easiest way in their life, without the need to do anything and waits to be served, in another words, the laziness of human beings caused the existence of robots. Example, there are robots being invented to clean and vacuum the house. Apparently, human in the world today are so lazy until they do not wish to do the household chores by themselves. Although this statement is not fair, but yet this is one of the very true facts. For workaholics, these robots are perfect in sharing responsibilities of household chores. 2.3 How do they exist? 2.3.1 Components of Robots For the basic layout of the generalised robots which are mostly correspond to animal, or even a human, are being made up with these components: The Brain Just as humans brain, it is the main system that operates a robot. It is a microprocessor which functions like a computer. Specialised programs are installed so that they can move without the controls of human. The Eyes There are made up from camera, sensor, ranging sonar and etc. There are used for navigating the robots movement, capture and recording the images of its surrounding, and estimate the range of its movement towards any objects or destination. There are also sensors that can help the robots to avoid from obstacles while moving. The Ears Some robots have been invented with sound recognition features. So, these robots require ears. Basically, the ears of these robots are also made up from sensors to detect sound waves and they are to be sent to microprocessor for detailed analysis. Communication System Communication between robots and human are greatly important. Besides receiving commands and orders from their owner, it is also generally important for the robots to tell their owners when something goes wrong. These communication systems can be in form of sound alarms or lights to grab the attentions of their owners. In order to transmit the sound or light, they need components like data, video or sound transmitters. Muscles It is the main component for the robots to move their limbs and carry out tasks. The limbs are commonly operated by electricity. In this case, the electricity functions as the muscles. However, some robots have been designed and created to do heavy duties like carrying heavy objects. Thus, electricity will be substituted with hydraulic technology or pneumatic technology. Limbs They can be as usual as humans hands and legs, fingers and toes. But in some situations, hands and legs are not that suitable to be used. Hence, the limbs of these robots are also available in wheels, tires, track rollers, propellers and etc. 2.3.2 Technologies Involved 2.3.2.1 Sensor Technologies A  sensor is a device, which is use to senses the objects and the surrounding. There are many kinds of applications for sensors which most people are never aware. Applications include cars, machines, aerospace, medicine, manufacturing and robotics. Sensors are the sensory system for robots, are much like humans 5 senses: sight, touch, smell, hearing, and taste. The robots sensors sense the environmental like touch, distance, light, sound, strain, rotation, magnetism, smell, temperature, inclination, pressure, or altitude. Then it provides the data that must be processed to provide information to allow the robot to respond. Robots are equipped with sensors so they can have an understanding of their surrounding environment and make changes in their behavior. The following are the common sensors used in robots [3]: Rotation Sensors They are used to measure the angle of a robotic arm, or how far a mobile robots wheel has turned. Global Positioning Systems Global Positioning Systems (GPS) receive signals from orbiting satellites that pinpoint the location of an outdoor robot on the Earth. Laser range Finder Laser range finders use laser beams to measure the distance to objects. They are used for obstacle detection and navigation. Computer Vision Computer Vision  is the field of study of interpreting camera images for a variety of purposes. Cameras are very common sensors; it can be say as the eyes of robot. Light Sensor Sensor for measures and differentiate light levels reflected from bright and dark surfaces. It is also use as the eyes of the robot, it helps in navigating, detect bright object, tell the different between coloured objects. Touch Sensors The uses of touch sensors are to detect contact between the robot and external objects surround it. Other example of sensors [4]: Ultrasonic Range Sensors Infrared Sensors Inertia Measurement Unit Accelerometers Current and Voltage Sensors Temperature and Humidity Sensors Camera and Vision Sensors Obstacle Detectors Force Sensors Sound detectors and etc. 2.3.2.2 Hydraulic Technologies Hydraulics  is the equipment or machinery involves or is operated by a fluid that is under pressure, such as water or oil.  This system used to increase the power of force to produce maximum energy required. Hydraulic systems are widely used in various industries to operate and manufacture many products. Hydraulic usually applied on machines and robotic part [5]. 2.3.2.3 Pneumatic Technologies Pneumatics technology is operated by air under pressure and it is powerful. Pneumatic means filled with air. It is quiet similar to hydraulic, the only different are it is operated by air, where as hydraulic is operated by liquid. Examples of pneumatic systems: Air compressor, electro-pneumatic action, tubular-pneumatic action, vacuum pump, compressed-air engine, air brakes, air engines, pneumatics launchers Pneumatic robot arm operated by human. Pneumatic can have long operating lives and require very little maintenance, but it is not easily damaged by shock [6]. 2.4 Uses of Robots in Various Fields 2.4.1 Medical Field An endoscope A laparoscopic surgery machineWhen we talk about robots performing tasks of human, we talk about future. But the use of robots in surgery is already a reality. The developments of technologies have brought various robotic devices into the medical field and these advanced robotic devices have been performing as a great assistant in a surgery room for today. With these robotic systems, the operation has become much less invasive but however, due to some disadvantages of these systems, surgeons are still cannot being replaced. Minimally invasive surgery is a broad concept including many common procedures that existed prior to the introduction of robots, such as gall bladder excisions. It refers to procedures that avoid long cuts by entering the body through a small entry [7]. However, surgeons can perform this procedure by using long handled surgery equipments and the guidance of viewing equipment such as endoscope; therefore it is not a necessary to use robots to do that. But yet, it d oes not mean robots are then do not categorised under minimally invasive surgery. Robot-assisted surgery system can be divided into 3 kinds which are supervisory-controlled system, telesurgical system and shared-control system. First, supervisory-controlled system is a system that allows the robots to perform tasks individually which will act according to the computer programme where the surgeons inputs into them earlier. Next, the telesurgical system which is also known as remote surgical requires the direct involvement of surgeons to conduct the robots arm rather than allowing it to perform surgery procedures by itself. Because the robot is still technically performing the procedures, so it is still considered under the subgroup of robotic surgery. The third system will be shared-control system. In this system, it requires the most involvement of surgeons. The surgeon carries out the procedure with the use of a robot that offers steady-hand manipulations of the instrument. This enables both entities to jointly perform the tasks [7]. Overall, the main difference between these 3 systems is the degree of interaction between the surgeons and the robots during the procedures. [8] Although the robot-surgeons can perform as a great assistant in surgery rooms, however there is nothing to be one hundred percents safe, including these robots. Mechanical devices including robots have the potentials to be malfunction and contravened the concept of minimally invasive surgery, or even worse, causing harm to the patients. Hence, safety of using these equipments has been questioned. Manufacturers have endeavoured to reduce the risks of malfunctioning of robots by installing related safety features. Nevertheless, these safety measurements have caused these robots increase in cost, making them unaffordable. Source: Table from Howe, RD, Matsuoka, Y. Robotics for Surgery. Annual Review of Biomedical Engineering. 1999, 01:213. The following table shows and compares the strength and limitation of using human-surgeon and robot-surgeon: 2.4.2 Military Field The military does not usually use the term robot, but they categorise and name the robots into Unmanned Aerial Vehicles (UAVs), Unmanned Ground Vehicles (UGVs) and Autonomous Underwater Vehicles (AUVs), depending on the environment they operated. Using of these robots in the war field can always being seen by technology-advanced countries, especially United State. Instead of sending their armies to combat in the war, they dispatch robots with weapon-equipped to the field. Even though they claimed that with this it can reduce the sacrificing of their armies but in fact, they are creating a larger offense towards their so-called enemy which may also cause more injuries to the innocents during the war. Yet in this decade, with the rapid increasing in research and development, scientists and researchers have manufactured robots that do not fight but to safe the people and also recovering the situation to a safety level. Let us discuss these military robots according to their categories. TALON SWORDS with different weaponriesUnmanned Ground Vehicles [9], or UGVs, are vehicles that require the needs of human to operate through remote-controlled system via a wireless communication link. UGVs are commonly telepresence robots which they are able to send feedback of images captured by video cameras which have been installed, to the operator. There are also robots equipped with weapon, and the most popular of its kind is TALON. According to Foster Miller [10], TALON is now a military robot that has most advanced technologies installed in it which it can moves through sand, water, snow and even staircases. With the cameras installed, it can transmit images in colours, black and white, infrared and night vision to the operator who is far away for up to 1km. SWORDS [11] or Special Weapon Observation Reconnaissance Detection System is a system where robots are granted with weapons and it was specially designed for the US armies. These robots were ever used by US Special Forces in the war against the Taliban in Afghanistan as well as the role to dispose explosive mines. Besides, there are also robots/vehicles that perform autonomously. Autonomous UGVs basically do not BEAR Rescue Military Robot involve in combat, but they carried out tasks like logistics, supplying of materials to the war fields, rescue operation, fire fighting, mine detection and disposal and etc. Rescue operation has been carried out by robots in an active battlefield to take care of the casualties and if necessitate, carry the casualties out from the field. The BEAR rescue military robots [12] have been designed with powerful upper body with hydraulics technology, track rollers as legs and dynamic balancing behaviour. UAVs with Hellfire-Missiles Next, robots that navigate in the sky without intervention human crews are called Unmanned Aerial Vehicles [13], or UAVs, but can be partially operated through remote or in this decade; they have been invented to be fully autonomous through pre-programming flight plans. UAVs are available in various shapes, features, characteristics and configurations. They have been widely used in a lot of countries to play a role in battlefields, logistic (cargo), research and development, civil and commercial. For most of the time, they have been a great assistant for the soldier troops to provide battlefield intelligence and bombard the targeted area. Military UAVs have been installed with various weapon including missiles and bombs. The US Army has been using this feature during their conquering in the war [14] with Afghanistan, Pakistan, Yemen and Iraq. In between, error targeting and faulty intelligence caused numbers of innocent civilian to dead. Due to large size of common UAVs, tiny spy robots Robot Flies [12] have been created so to access into confined and cluttered spaces within the buildings, tunnels, stairwells or caves for surveillance and reconnaissance purposes. It is stated that there are also possibilities to equip these robots with small explosive charges to destroy on a small specific area instead of destroying the whole. Robot Fly Remotely Operated Vehicles (ROVs)Subsequently, the underwater robots AUVs, in full Autonomous Underwater Vehicles are also known as Unmanned Undersea Vehicles (UUVs). AUVs are basically works within the sea without any intervention of human. Whereas the non-autonomous called Remotely Operated Vehicles (ROVs) are controlled by the operator from the surface through umbilical. In military field, AUVs are used to detect if there are any mines and to monitor the protected area for new unidentified objects. For the purpose of warfare, AUVs are employed to detect and resist the invasion of manned submarines [15]. From the research, AUVs are not so popular to be employed into the military fields as wars under the water are so seldom to be seen. 2.4.3 Industrial Field Robots employed in industrial field are static robots which are majorly automated and allowed to make decision via pre-programmed inputs. These robots are more common to be seen in form of arm-shaped. They will not have the components of head, body and legs, but just arm. In earlier decades, mans responsibilities in manufacturing process like welding, painting, assembly,  pick  and place,  packaging  and  palletizing, product inspection, and testing have been displaced by robots today. The introduction of robots into industrial field is a great contribution as they can accomplish their tasks in a faster way, more efficient and highly better than a man can do in term of precision and endurance. The different between each arms and the functioning role of the arms are depending on the tools that are fixed at the end of the arm, or they call them the end-effectors. Industrial robots can also being classified into [16]: Vertically Articulated The multi-jointed arm of a vertically articulated robot is connected to the base with a twisting joint. The links in the arm are connected by rotary joints. This type is  often called jointed-arm. [16] Cartesian Coordinate This robot is limited to x, y, and z movement. It is  also called a rectilinear robot. All of the robot arm links are connected with linear joints. The physical appearance is square [16]. SCARA The Selective Compliance Assembly Robot Arm  is ideal for precision work within one plane. Its work envelope is cylindrical. It has two horizontal joints [16]. Cylindrical The robot has one rotary joint at the base and two linear joints to connect the links. Their work envelope is also cylindrical [16]. Polar The arm is connected to the base with a twisting joint and a combination of rotary and linear joints. They have a spherical-shaped from outside look [16]. Delta This robot configuration combines a rotational joint and parallelograms. Delta robots work within a dome-shaped work envelope [16]. Welding arm Welding devices such as MIG-welding gun are one of the popular robot guns that are widely used in the industry to assembly their products. Welding arms are programmed to carry out specific task welding process repeatedly, fusing of adjacent parts together with uniform quality at a rapid speed. Robot Spray ArmThe next tool will be the Spray Gun. As we know, Spraying evenly on the surface is never an easy job for human. Hence, it is also popular to apply the spray gun into robot arms to do spraying for human. Besides to achieve nearly perfect quality or spraying, they also help to relieve the human from this hazardous and skilful job. Liquid used in the spray contained various unknown chemicals that might cause harm to human. At the same time, spray gun will not waste paints hence reducing the cost. Robot arm that can lift up heavy objects. Picture showing a man carried by robot arm.Picking, lifting and placing applications can be done through installing grippers. Materials used in industries are normally big and heavy. Besides of using electro-mechanical technologies, hydraulic and pneumatic technologies that produce multiply forces can be applied to the arm. Picking up of some objects haven been done by vacuum. To make sure the positioning of these devices are constant and accurate, location sensors have been installed as well [17]. 2.4.5 Space Exploration Field When it comes to space exploration, by automatically we know that robots have been contributing a lot, or accomplishing most of the space exploration tasks. The only planet that human has set foot on, besides Earth is the Moon. However, our tremendous robots have set their feet in planets like Mars, Venus, Jupiter and including few comets and asteroids [18]. Without them, human will not be able to know how the other planets look like and of course, without them human will never know that aliens do not appear in the planets within Solar System. We would not conclude that aliens do not appear in our real life because there are no researches stating that robots have been successfully sent out and explored the whole Universe and so, we never know what is going on outside our Universe. Robots have been used widely in this field because of the not-habitable environment for human beings. Eliminate the matter of oxygen; human are not able to cope with the different pressure and gravitational force on the other planets. Therefore costly astronaut suits have been created and in fact they are already being created, and this will never be an intelligence act. There are also risks involved when sending human to the planets and back to the Earth. Several cases happened in the past where explosions of space shuttle caused death to human. Logo of NASAIt is common when people talk about space exploring, they will think of NASA [19], in full National Aeronautics and Space Administration. NASA is an agency that has been established on July 29, 1958. Before the establishment of NASA, National Advisory Committee for Aeronautics  (NACA) is also an agency which is responsible for every space programs in United States. NASA has led the human nation towards the knowledge of space, after launching Apollo to the Moon, and then invented and released the space station, Skylab and later the Space Shuttle. The historical moment when Neil Armstrong represented his nation to be the first man to step on the Moon.Apollo program is one of the worlds most amazing events in the history that it was the first program that brought human to the Moon and back to the land safely. Apollo 1 caused a tragedy that kills all the astronauts who were inside due to a fire during experimental simulation. Thus, several experiments and observations had carried out before they boarded the human and sent them to the Moon. At last Apollo 11 had successfully landed the first men on the moon, Neil Armstrong and Buzz Aldrin [20]. Skylab was the first space station that had been launched to the orbit by United States in 1973. In the space station there are laboratories prepared for the researchers to carry out scientific experiments and studies such as the Sun, space flight, metallic-crystal growth, microgravity, and solar observatory. But in few years time, Skylab fell from the orbit on 11 July 1979. Currently Skylab have been replaced and named as International Space Station (ISS) [21]. The famous robots in space with no doubt have to be the series of Orbiters, Rovers and Landers that have been sent to Mars in the previous years. The first orbiter which was sent to Mars on July 14, 1965 is Mariner 4. Launching of Mariner 4 has been a great achievement as it enables the human to have a closer relation on the other planets after Great amount of water required to cause the erosion shown. Picture taken by Viking 1 on Mars.it sent back the photos of Mars. In the series of Landers, 2 Viking Landers, Viking 1 and Viking 2 had been released to Mars in the year 1976 with the accompaniment of orbiters that send back photos and scientific data. Life detection application was installed to the landers to detect life on Mars but however, the result sent back an unclear data. From the newest research by NASA, they found that the Mars is covered with large amount of gas called Methane, which is also one of the main components found in the Earth. Methane gas in the Earth is largely produced by organism when digesting of nutrients. However, it can also being released to the air through geological processes. Thus, it is still unclear whether if there are organisms survive under the permafrost layer of Mars [22]. There are other more advance robots that have been sent for planetary exploration. These include Sojourner and Mar s Exploration Rovers (MERs). The 2 robots mentioned are tele-operated which they required humans control. However, MERs have been a better robot due to larger mechanical size and also equipped with better communication and instrumentation than Sojourner. Sojourner was sent to Mars in 1997 and MERs is in 2004 [24]. However, in such numbers of space robots, Sputnik 1 has been the very first robot that was sent to the space. Mariner 2 by U.S. was the first robot that flown to Venus on 12 December 1962. In the same year, a Russian space robot, Venera 7 was the first human-made vehicle to successfully land on another planet and transmits data back to Earth. Voyager 1There was a mission, the Voyager mission, sent robot and explore the world outside of our Solar System. Voyager 1 and 2 were launched in 1977. Voyager 1 as in June 19, 2009, was at a distance about 16.49 billion kilometres away from the Sun, currently the furthest man-made object in the space [24]. In these decades, there are numerous missions that have been set and hopefully soon or later, robots can help to accomplish these missions. 2.5 Side Effects of Robots The side effect of robots is mean that the negative issues or disadvantages which robots will bring to our world if there are over used or over populated. Although robots is create to assist us human to improve our life, but they may bring harm to us as well if we do not use them wisely. From the research we made, there are some disadvantages of robotic system and robots, when normal people to operate the robots, the functions are limited and only the creator or programmers what those functions are. Although robots is been programmed, but they may not function properly in case of an emergency or unexpected occasion. The cost for built the robots and robotic systems are very high, this make it needs to have full consideration before built it. Besides, it may need to have more extra funds and spaces to provide the facilities to build the robots. There are some moral issues occur if the robotic systems and robots have over used. The too much using of robots and robotic systems in our society making us human beings become more dependent upon robot. Because of this, many people will always depend on robots to done their works (this could be possibly happen like in the movie Surrogates, where the human just stay in their home and control their look alike robot to works). The advance use of robots and robotic systems may replace the human labour and causing people to lose their jobs and facing economic matter. In medical field, if the robotic systems and robots have taking over majority of the doctors job for example, certain surgeries, this may cause certain people may not be able to access the services due to lack of funds. This may also happen in some other fields, this can be describe in military field, because robots are more advance therefore, which country that are rich and own many military robotics system and robots will be the most powerful country. These mean that, if we do not want this negative effect to be happening in the future, we should wisely use the robots and balance the functi

The Natural :: Essays Papers

The Natural Iris vs. Memo, the everlasting battle of Good and Evil, Good Angel vs. Bad Angel. In The Natural the Angels take the form of women that interact with Roy. Iris the â€Å"Good Angel† has nothing but a positive influence on Roy and cares about him deeply. The exact opposite of Iris is the â€Å"Bad Angel† Memo who cares just about what she can get her hands on except poverty. To her nothing or nobody matters. The reason Memo’s able to sneak in with Roy so easy is that she uses her body, her looks. She makes Roy a â€Å"toy† to her. She wants money so badly, that’s why she’s always with people like Gus or the Judge, because they are the rich people who like to spend a lot of money. Memo has always been mean to Roy: She hadn’t treated him right. For a while things had looked so good†¦ but no sooner has he gone into a slump when she began again to avoid him. Had she been nice to him instead, he’d have got out of trouble sooner (165). Iris is really â€Å"laid back† when it comes to Roy. Iris isn’t as attractive as Memo, but she looks past the dollars and sees what she likes. Each â€Å"Angel† has a different effect on Roy both being on and off the field. Roy goes out with Memo ignoring Pop’s warning â€Å"†¦She is unlucky and always has been and I think that there is some kind of whammy in her that carries her luck to other people† (136). Roy goes into a bad slump. Everything he does fails until one game in Detroit. The lady in the stands hesitantly rose†¦ She was an attractive woman, around 30, maybe more, and built solid but not too big†¦ A reporter approached her and asked her name but she wouldn’t give it to him, nor would she, blushing, say why she was standing now (159). The woman standing is Iris and she is standing because she believes in Roy, and wants him to regain his confidence by showing her support.
