About Plato and His Philosophical Ideas
Plato was one of the most famous, respected, and influential philosophers of all time. A type of love (Platonic) is named for him. We know the Greek philosopher Socrates mostly through Platos dialogues. Atlantis enthusiasts know Plato for his parable about it in Timaeus and other descriptions from Critias. He saw tripartite structures in the world around him. His social structure theory had a governing class, warriors, and workers. He thought the human soul contained reason, spirit, and appetite. He may have founded an institution of learning known as the Academy, from which we get the word academic. Name: Aristocles [dont confuse the name with Aristotle], but known as PlatoPlace of Birth: AthensDates 428/427 to 347 B.C.Occupation: Philosopher The Name Plato Plato was originally named Aristocles, but one of his teachers gave him the familiar name, either because of the breadth of his shoulders or his speech. Birth of Plato Plato was born around May 21 in 428 or 427 B.C., a year or two after Pericles died and during the Peloponnesian War. He was related to Solon and could trace his ancestry to the last legendary king of Athens, Codrus. Plato and Socrates Plato was a student and follower of Socrates until 399, when the condemned Socrates died after drinking the prescribed cup of hemlock. It is through Plato that we are most familiar with Socrates philosophy because he wrote dialogues in which his teacher took part, usually asking leading questions -- the Socratic method. Platos Apology is his version of the trial and the Phaedo, the death of Socrates. The Legacy of the Academy When Plato died, in 347 B.C., after Philip II of Macedonia had begun his conquest of Greece, leadership of the Academy passed not to Aristotle, who had been a student and then teacher there for 20 years, and who expected to follow, but to Platos nephew Speusippus. The Academy continued for several more centuries. Eroticism Platos Symposium contains ideas on love held by various philosophers and other Athenians. It entertains many points of view, including the idea that people were originally doubled -- some with the same gender and others with the opposite, and that, once cut, they spend their lives looking for their other part. This idea explains sexual preferences. Atlantis The mythical place known as Atlantis appears as part of a parable in a fragment of Platos late dialogue Timaeus and also in Critias. Tradition of Plato In the Middle Ages, Plato was known mostly through Latin translations of Arabic translations and commentaries. In the Renaissance, when Greek became more familiar, far more scholars studied Plato. Since then, he has had an impact on math and science, morals, and political theory. The Philosopher King Instead of following a political path, Plato thought it more important to educate would-be statesmen. For this reason, he set up a school for future leaders. His school was called the Academy, named for the park in which it was located. Platos Republic contains a treatise on education. Plato is considered by many to be the most important philosopher who ever lived. He is known as the father of idealism in philosophy. His ideas were elitist, with the philosopher king the ideal ruler. Plato is perhaps best known to college students for his parable of a cave, which appears in Platos Republic.

Methods of Studying Human Behavior - 1758 Words
Methods Of Studying Human Behavior There are several methods used to study human behavior including Naturalistic Observation, Correlational Research, Experimental Method, Case Study, and the Survey Method, each uses a different type of approach. If I were to do a study on the relationship between alcohol and violence, the method I would use would be the survey research method. (Stangor, 2010) I would use this method because it would not be intrusive, require any possible harm to anyone, and has minimal ethical concerns. The Survey Research Method is a type of Descriptive Research Design that uses written questionnaires, and interviews to collect data. The people participating in the study are referred to as the Sample, and theâ⬠¦show more contentâ⬠¦An example of positive reinforcement in my personal experience is making the Presidentââ¬â¢s List Honors, the award is the positive reinforcement and achieving good grades is the target behavior. An example of negative reinforcement for me is taking pain medication for migraineââ¬â¢s. The migraine is the negative reinforcer to the pain medicine and it removes something unpleasant, which is the pain. Shaping is the process of creating a new behavior which occurs through the use of reinforcements to help reach the desired behavior. It is a conditioning tool used to determine, by the consequence of the action, if the action will be repeated. An example for me personally is learning how to be a good student while raising a baby. I have been out of school for about 20 years. I had a baby a little over a year ago and it has been 12 years since I had a baby. I had to adjust to being a student and new mother again and at the same time. This required me to learn how to manage my time and prioritize all of my responsibilities in order to have the time to study in order to get good grades and take care of a baby. By creating schedules and balancing my time, with adjustments as needed along the way, I am a A student and full time mom. The reinforcements that have helped me achieve this behavior would be the reward of a 4.0 GPA, personal satisfaction knowing I can be both a student and mom, and knowing that I will be able to provide a better life for my kids when once IShow MoreRelatedDog Training Advice And College Study Advice998 Words à |à 4 Pagesdifferent than studying for a Biology exam, but online advice on both topics are surprisingly similar.

Publication in This Series about Accountingââ¬Myassignmenthelp.Com
Question: Explain on Publication in This Series about Accounting? Answer: Introduction The communications core consists of a communications strategy, delivery skills and a comprehensive communications plan. The first publication in this series about effective executive communications presented a strategy for effective communications and discussed how effective CEOs build their communication skills. This publication, the second in the series, discusses how to develop a communications plan (Bargiela-Chiappini,2014). Key Findings To deliver great business communication, CEOs and other business executives must build an effective communications core, which consists of a communications strategy, a communications plan and delivery skills. As with any business initiative, effective planning increases the likelihood of success. By formalizing a communications plan and adopting a disciplined approach to using it the quality of communications can improve over time. Recommendations Round out your communications core by developing a communications plan for your organization. Effective communications is a core leadership competency. Engage your organization in developing a communications plan to begin building this competency in your leadership team. While this formal definition of communication captures the mechanical act of imparting information, it neglects to consider the human elements of inspiring, exciting or calming. The roles of the business and the executive team will change, depending on the purpose of the communication, and the roles may include that of a steward (of information), a motivator, change agent, consultant or inspirer. A good communications plan specifically documents the purpose of a communication. It is continually revisited and refined after every communication as more becomes known about stakeholders and their current stance on the topic. When the purpose of a communication is to inform stakeholders, the expectation is that the message recipient is not expected to do anything, except to be aware. The business and executive team are acting as stewards for the organization imparting necessary information as needed across the organization or to a particular person. For example, as a new executive joins the organization, it is wise for the business to meet with the person and give the person a background or history of how business has benefited his or her area in the past. When requesting something from somebody, the business is motivating that person to do something. An example might be to have the difficult conversation with an executive about becoming a more visible project sponsor. As a change agent, the business is trying to position an effort within the organization that will require much change. For example, changes to the supply chain tend to have a significant impact on the organization. Carefully engaging the impacted organizations to appreciate the reasons for the change, the benefits of the new operating model, and their roles and responsibilities in the effort will significantly increase the likelihood of success. And, finally, inspiration is often required to help an organization engage in significant change or to overcome difficult times, such as when leadership changes or layoffs occur. The purpose of this role is not only to inspire people to stay engaged with the organization, but also to understand the change well enough to become champions of the effort as well. Communicator Stakeholder Communication is a two-way street, so the first question to answer is, "Who should deliver the message?" A message is typically delivered by peers across the organization, from executive to executive or manager to manager. The advantages of this approach are twofold: Relationships are built at all levels across the organization, and business employees are given the opportunity to build a critical leadership skill. The second question to ask is, "Who needs to receive the message?" Typical stakeholder segments include the board of directors, executive team, midlevel management, user community, business leadership and business staff. Less familiar segments, but ones that CEOs should increasingly consider, are customers and the media. A great communication accounts for the attributes of stakeholders. Understanding both the common and unique attributes of stakeholders will help effectively shape the messages to be delivered. Delivery Method Consider what the best method or channel is to deliver the communication. What must be taken into account when determining the most effective method of communication for the situation? A good communication considers all the avenues available from face to face to phone to e-mail. Selecting the right delivery method is key to demonstrating consideration for the role of the stakeholders, successfully drawing their attention and engaging them to act on the message Delivery Frequency How often and at what times do you need to communicate? Frequency should vary based on the purpose of the communication, the specific needs of the stakeholders and the type of message content. Some guidelines: In emergency situations, engage quickly and communicate frequently throughout the crisis period. After each communication, announce when people can expect to hear the next update. If the goal is to achieve a high degree of internalization among stakeholders, engage in more frequent communication, using a "build" approach. Each communication should delve deeper into the topic than the previous communication. Understanding how particular stakeholders internalize information will help determine how often and when to communicate. The more important it is for a stakeholder to internalize the information and take action on the communication, the more frequently these communications should be delivered. Measures of Success Consider the results of the communication. Are they what you expected? If the goal of communicating an business strategy was for a business executive to understand how their organization is impacted by the strategy, can this executive effectively articulate the business change? If not, then take the opportunity to refine your plan using the feedback received to move closer toward achieving the desired results. Consider applying formal and informal measures of success for more common, regular communications, and informal measures for special, out-of-the-ordinary communications. And, finally, inspiration is often required to help an organization engage in significant change or to overcome difficult times, such as when leadership changes or layoffs occur. The purpose of this role is not only to inspire people to stay engaged with the organization, but also to understand the change well enough to become champions of the effort as well. Identify each type of communication you need to deliver in order to be effective within the enterprise. Examples include the business strategy or performance success of the business organization. Other common examples include project updates or results of employee opinion surveys. Once the list is completed, look at it with a critical eye: How many items are on the list? Are there more than 15 or 20? Remember, if you are communicating too much, you may be teaching people to ignore you. For each of the items you identified, spend time documenting its true purpose. What will you achieve by delivering this type of communication that you won't using any of the others on the list? It is far better to have fewer types of communications, and repurpose or reuse them for a particular audience or in a different venue, than it is to have many communications with a single purpose or use (Mai, R. and Hoffmann, 2014). Again, be critical about who should communicate this message. While this topic will be explored more in our next publication, remember that one purpose of this process is to develop a critical leadership competency. The phrase "spread the wealth" applies here. Consider creating liaisons between the business team and the rest of the enterprise at all levels not only to build this competency, but also to create a true relationship organization. Consider every person in the organization who needs to hear and internalize the message type you are considering. Answer the following questions to determine people's communications needs: Select a venue that is appropriate for the person or group to whom you are delivering the message, as well as for the type of communication you are delivering. For example, to e-mail an business strategy with no explanation would most likely defeat the purpose of the business strategy, which is to create a shared vision of the future through the use of technology. Conclusion While larger business organizations have teams dedicated to developing a communications plan for the organization, most organizations do not. Whether you have a dedicated communications department or not, after completing your plan for the organization, develop a timeline to achieve what you set out to do. Assuming you plan on building this skill within your organization, assign ownership for each type of communication to your teams, and establish a date when all tools will be developed for the communication. Come together again to review each of the tools, and assign one individual to ensure consistency across all of the tools. The communications tools you choose and use reflect the "business brand." By creating the same look and feel across all tools, you are subtly reinforcing that this is a communication from business and that it is important to pay attention.

Macbeth Story Essays - Characters In Macbeth, English-language Films
Macbeth Story MacBeth is the story of a great warrior who is tempted by evil and allows his ambition to corrupt his strength. MacBeth himself begins the story as being the greatest general in all of Scotland, but by the end is merely a shadow of his past self as he is the detested tyrant who is slain by Macduff. Although MacBeth is physically strong in the beginning of the story, he turns out to be emotionally weak. MacBeth's physical strength is not just encompassed by his might, but also by his keen sense on the battlefield and his devotion to the people around him. MacBeth begins the story by killing a traitor himself, the Thane of Cawdor, Macdonwald, through seemingly impossible odds. Because of this act, King Duncan proclaims MacBeth the new Thane of Cawdor. It is generally accepted at this point in the story that MacBeth is the most skilled warrior in all of Scotland, and is recognized as such by all characters. His strength was the one thing that allowed him his rise to power, but it was that rise to power that eventually sapped him of all his strength. MacBeth's strengths soon became his weaknesses, as his ruthlessness when it came to whom he perceived to be his enemies came back to him as Macduff slew him towards the end of the play. MacBeth was also easily duped, as his wife was able to convince him to kill the King, even though MacBeth had already decided to not kill Duncan. MacBeth's keen mind was brought down by the guilt he felt over killing Duncan, and this guilt was compounded when he ordered the killing of his best friend, Banquo. This became highly evident as he began seeing visions of the bloody daggers he used to kill Duncan and the vision of Banquo's ghost at his feast. MacBeth also becomes disillusioned with his marriage as the story moves on. He referred to his wife as "my dearest partner of greatness" (1.5.11) in the beginning, yet when he is informed of his wife's passing, he says, "She should have died hereafter. There would have been more time for such a word." (5.5.20) showing his emotional instability, something that he was always able to keep in check. MacBeth's character changes from a physically, mentally, and skillfully strong General of the Scottish army to a tyrannical, despised and defeated King of Scotland. MacBeth as a play captures the complete and utter fall from grace of a man not able to deal with the temptations of evil.

Types of Accountability Essay Example For Students
Types of Accountability Essay Bruce Stone, O. P. Dwivedi, and Joseph G. Jabbra list 8 types of accountability, namely: moral, administrative, political, managerial, market, legal/judicial, constituency relation, and professional. Leadership accountability cross cuts many of these distinctions. Political accountability Political accountability is the accountability of the government, civil servants and politicians to the public and to legislative bodies such as congress or parliament. In a few cases, recall elections can be used to revoke the office of an elected official. Generally, however, voters do not have any direct way of holding elected representatives to account during the term for which they have been elected. Additionally, some officials and legislators may be appointed rather than elected. Constitution, or statute, can empower a legislative body to hold their own members, the government, and government bodies to account. This can be through holding an internal or independent inquiry. We will write a custom essay on Types of Accountability specifically for you for only $16.38 $13.9/page Order now Inquiries are usually held in response to an allegation of misconduct or corruption. The powers, procedures and sanctions vary from country to country. The legislature may have the power to impeach the individual, remove them, or suspend them from office for a period of time. The accused person might also decide to resign before trial. Impeachment in the United States has been used both for elected representatives and other civil offices, such as district court judges. In parliamentary systems, the government relies on the support or parliament, which gives parliament power to hold the government to account. For example, some parliaments can pass a vote of no confidence in the government. Ethical accountability Ethical accountability is the practice of improving overall personal and organizational performance by developing and promoting responsible tools and professional expertise, and by advocating an effective enabling environment for people and organizations to embrace a culture of sustainable development. Ethical accountability may include the individual, as well as small and large businesses, not-for-profit organizations, research institutions and academics, and government. One scholarly paper has posited that it is unethical to plan an action for social change without excavating the knowledge and wisdom of the people who are responsible for implementing the plans of action and the people whose lives will be affected. Administrative accountability Internal rules and norms as well as some independent commission are mechanisms to hold civil servant within the administration of government accountable. Within department or ministry, firstly, behavior is bounded by rules and regulations; secondly, civil servants are subordinates in a hierarchy and accountable to superiors. Nonetheless, there are independent ââ¬Å"watchdogâ⬠units to scrutinize and hold departments accountable; legitimacy of these commissions is built upon their independence, as it avoids any conflicts of interest. Apart from internal checks, some ââ¬Å"watchdogâ⬠units accept complaints from citizens, bridging government and society to hold civil servants accountable to citizens, but not merely governmental departments. Market accountability Under voices for decentralization and privatization of the government, services provided are nowadays more ââ¬Å"customer-drivenâ⬠and should aim to provide convenience and various choices to citizens; with this perspective, there are comparisons and competition between public and private services and this, ideally, improves quality of service. As mentioned by Bruce Stone, the standard of assessment for accountability is therefore ââ¬Å"responsiveness of service providers to a body of ââ¬Ësovereignââ¬â¢ customers and produce quality service. Outsourcing service is one means to adopt market accountability. Government can choose among a shortlist of companies for outsourced service; within the contracting period, government can hold the company by rewriting contracts or by choosing another company. Constituency relations Within this perspective, a particular agency or the government is accountable f voices from agencies, groups or institutions, which is outside the public sector and representing citizensââ¬â¢ interests in a particular constituency or field, are heard. Moreover, the government is obliged to empower members of agencies with political rights to run for elections and be elected; or, appoint them into the public sector as a way to hold the government representative and ensure voices from all constituenc ies are included in policy-making process.

Legal scholar Anne Davies, for instance, argues that the line between public institutions and private entities like corporations is becoming blurred in certain areas of public service provision in the United Kingdom and that this can compromise political accountability in those areas. She and others argue that some administrative law reforms are necessary to address this accountability gap. With respect to the public/private overlap in the United States, public concern over the contracting out of government (including military) services and the resulting accountability gap has been highlighted recently following the shooting incident involving the Blackwater security firm in Iraq.

Asian Brown Cloud essays
Asian Brown Cloud essays The report by the United Nations Environmental Programme (UNEP) on the three-kilometre brown cloud hanging over Asia zeroes in on this kind of fuel burning as the source of the cloud that is disrupting monsoons, lowering agricultural output and creating air pollution leading to respiratory diseases. "The big problem here could be cooking at home," says Nobel laureate Paul Crutzen of the Max-Planck Institute for Chemistry in Germany. Crutzen won the Nobel Prize for his work on discovering the ozone hole. It is a problem that will now have to be addressed by governments in South Asia, says Prof V. Ramanathan of the Scripps Institute of Oceanography, one of the leading scientists involved in the study, conducted between 1995 and 1999 at a cost of about $40 million. "The sliver lining to this cloud is that it can be tackled relatively soon if the correct policy decisions are taken," he says. The Supreme Court of India took the lead in introducing compressed Natural gas (CNG) in buses, taxis and auto-rickshaws in the country. But the court had no idea of the magnitude of the cloud hanging overhead which its order could do nothing to remove. The cloud cannot be tackled at the level of handling pollution in New Delhi or some other cities. Ramantahan says: "We are seeing great variation in this cloud not just across Asia but over parts of India as well." The Asian Brown Cloud, as the scientists are calling it, "should not be seen as something static," he said. "It is moving about all the time." Scientists indicate a revolution of lifestyles will be needed across India, Pakistan and China acting together. This will mean common policies against burning of fossil fuels, of agricultural wastes, against emissions from industries and power stations, and above all, against emissions from the millions of inefficient cookers in homes using fuels like wood and cow dung. The brown clouds these fuels have created over Asia have ...

System Analysis and Design Assignment Example | Topics and Well Written Essays - 750 words - 1
System Analysis and Design - Assignment Example Additionally, in terms of their real-world modeling, the system models the real world to a complete fashion compared to the traditional technique. The objects are categorized into objectââ¬â¢s classes and the objects are associated with the behavior, this is because it is not based on processing and data but rather on objects. The object-oriented method is more reliable compared to the traditional system. This is because new behaviors can be developed from the existing projects. This is because the objects can be accessed and called dynamically. The object-oriented approach has high code reusability. After creating new objects, the project will automatically update the data characteristics and attributes of the previous project. There will also be data inheritance from the super classes that participated. When users create a new widget, the created project will behave ââ¬Å"wittyâ⬠. The analyst needs to start learning object-oriented techniques first. Learning the technique first will expose the analyst to promote greater maintainability and flexibility in the field of analysis. The technology has also proven to be popular in almost every field of software development. There the analysts need to have a basic understanding of the technology paradigm in order to develop sustainable software solutions. Therefore, the analyst needs to start learning the object-oriented techniques (Rosenblatt, 240). In the field, the analyst will be required to describe the functionality of the object-oriented system, and how the object-oriented system should be developed in ways that are conducive to flexibility and maintainability. Here, the analyst will be guided through using case survey, creating UML diagrams, applying high cohesion and low coupling, and produce codes from the design, and later understand time for creating design artifacts and analysis.

Guillermo Furniture Store Scenario Essay Example | Topics and Well Written Essays - 500 words
Guillermo Furniture Store Scenario - Essay Example This case study concerns the strategic challenges faced by a relatively small but successful local furniture maker in the face of a large foreign competitor with superior technology and lower prices. The salient facts are as follows. a. A new competitor entered from overseas, with high tech methods and low prices. The plant in Norway was highly automated, used very little labour (used robotics). Production could move between products quickly, and runs on a 24- hour basis (shift-differentials could be more than offset by reduction in labor). 1. Guillermo may tie up with a Norwegian competitor which did not want to operate retail outlets locally but preferred to rely on chain distributors. Guillermo, while retaining the high-end custom work, intends to represent the Norwegian company, converting his companyââ¬â¢s primary focus from manufacturing to distribution. 2. Guillermo had a patented process for creating a coating for his furniture which was flame-retardant and, with further processing, stain resistant. There was market for the flame-retardant but not the finished coating. Budgets represent short-term financial forecast, particularly of expected cash flows, based on the business plans drawn by the company, to see if forecasted cash outflows and their timing could be sufficiently covered by cash inflows (revenues and liabilities), and if not, to allocate for future financing at the time they would be needed. Past performance reports to see the history of costs and sales, and to draw insights as to the behavior of costs and revenues given the environmental indicators. Ratios, trends and sensitivity analyses of costs and revenues compared to each other and to economic indicators is important in determining how the company will be affected by a prospective decision. Ratio analysis of historical and cross-sectional accounts are helpful

Assignment Example It is not true that cabbage is cheaply made and is of low quality. Red wine and beef steak are complimentary goods. The goods complement each other. A complementary good is one whose cross elasticity of demand is negative. That is, the demand of a complementary good will increase if the price of another good decreases. Similarly, the demand of a complementary good falls when the price of another good is increased. As such, because red wine and beef steak are complimentary goods (are consumed together), an increase in the price of red wine will discourage people from buying beef steak and thus a fall in demand for beef steak. Red wine has a negative cross elasticity of demand with respect to beef steak. The sales of generic frozen orange juice soared during recession because it is an inferior good. Inferior goods are those that provide an alternative for consumers to reducing their expenditure during harsh economic times. The demand for inferior goods soars with a decrease in the level of disposable income. On the other hand, the sales of freshly squeezed orange juice declined because it is a normal good. The demand for normal goods falls with a fall in income level. As such, during 2007/2008 recession, people turned to generic frozen orange juice to cut their expenditure and thus high sales recorded. On the other hand, the number of people buying freshly squeezed orange juice declined as their disposable income fell. At point A, change in price produces equal change in quantity demanded and hence elastic. At point B, the demand is probably inelastic because a change in price yields less percentage change in quantity demanded. The firmââ¬â¢s products have elastic demand. For goods with elastic demand, a small change in price will cause a big change in quantity demanded. Therefore, every time the firm increased the price, it Assignment Example | Topics and Well Written Essays - 250 words - 185 Assignment Example Joycelynââ¬â¢s objective of career development has been key to her high performance and provision of a worker friendly environment has enabled her to achieve a lot in her career (Mondy, Noe, & Gowan, 2005). Joycelyn has no longer taken human resource as a an administrative duty but as a responsibility to ensure that workers feel that their place of work as the right place to spend time due to the conditions that are provided by the employer.

Microcontroller Based DC Motor Speed Controller
Microcontroller Based DC Motor Speed Controller In this report I present a microcontroller based DC motor speed controller. DC motors play a vital role in most of the industrial areas. They are mainly used for the mechanical movements of physical applications such as media drives, power plants, lifts, elevators, conveyers, belt driven loads (printing press) etc. The controller implements the control strategy governing the load and motor characteristics. To match the load and motor, the input to the microcontroller is manipulated by the controller. The purpose of a motor speed controller is to capture a signal representing the demanded speed, and to drive the motor at that speed. The controller may or may not actually measure the speed of the motor. If it does, it is called a Feedback Speed Controller or Closed Loop Speed Controller, if not it is called an Open Loop Speed Controller. Feedback speed control is better, but more complicated, and may not be required for a simple circuit design. The former (closed loop) is implemented in the presented controller design. The subject arrangement consisted of a tachometer attached to the shaft of the motor. A controller design cannot be more accurate than methods aimed at measuring actual motor speed. This is readily attained by coupling the motor shaft with a tachometer. The tachometer output signal is converted to a dc voltage signal acceptable to the microcontroller. The microcontroller is programmed to drive the motor accomplishing the load requirement. The operation of dc motor was studied. Several types of motors and various control types were investigated. The project also intends to familiarize us with the efficiency of PIC in control systems. To evaluate the effectiveness of the controller, analysis will be conducted driving variable load while maintaining constant speed of the motor. The advantages of using microcontrollers to control dc motor were studied. INTRODUCTION 1.1 MOTOR An electric motor is an electromechanical device that converts electrical energy to mechanical energy. The mechanical energy can be used to perform work such as rotating a pump impeller, fan, blower, driving a compressor, lifting materials etc. It is estimated that about 70% of the total electrical load is accounted by motors only. 1.2 CLASSIFICATION OF MOTORS Electric Motors Alternating Current (AC) Motors Direct Current (DC) Motors Synchronous Induction Three-Phase Single-Phase Self Excited Separately Excited Series Shunt Compound FIG-1.1 classification of motors 1.3 AC MOTORS An AC motor is a motor that is driven by an alternating current. It consists of two basic parts, an outside stationary stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft that is given a torque by the rotating field. 1.3.1 TYPES OF AC MOTORS There are two types of AC motors, depending on the type of rotor used. The first is the synchronous motor, which rotates exactly at the supply frequency or a sub multiple of the supply frequency. The magnetic field on the rotor is either generated by current delivered through slip rings or by a permanent magnet. The second type is the induction motor, which turns slightly slower than the supply frequency. The magnetic field on the rotor of this motor is created by an induced current. 1.3.2 TYPES OF INDUCTION MOTORS Squirrel-Cage Induction Motors The most simple and reliable of all electric motors. It is essentially a constant speed machine, which is adaptable for users under all but the most severe starting conditions. Requires little attention as there are no commutator or slip rings, yet operates with good efficiency. Wound-Rotor (Slip Ring) Induction motor It is used for constant speed-service requiring a heavier starting torque than is obtainable with squirrel cage type. Because of its lower starting current, this type is frequently used instead of the squirrel-cage type in larger sizes. These motors are also used for varying-speed-service. Speed varies with this load, so that they should not be used where constant speed at each adjustment is required, as for machine tools. Single Phase Induction Motors This motor is used mostly in small sizes, where polyphase current is not available. Characteristics are not as good as the polyphase motor and for size larger than 10 HP, the line disturbance is likely to be objectionable. These motors are commonly used for light starting and for running loads up to 1/3 HP Capacitor and repulsion types provide greater torque and are built in sizes up to 10 HP. Synchronous Motors Run at constant speed fixed by frequency of the system. Require direct current for excitation and have low starting torque. For large motor-generators sets, frequency changes, air compressors and similar apparatus which permits starting under a light load, for which they are generally used. These motors are used with considerable advantage, particularly on large power systems, because of their inherent ability to improve the power factor of the system. 1.4 DC MOTOR Direct-Current motors, as the name implies, use a direct-unidirectional current. A DC motor has three main components: Field pole. The interaction of two magnetic fields causes the rotation in a DC motor. The DC motor has field poles that are stationary and an armature that turns on bearings in the space between the field poles. A simple DC motor has two field poles: a north pole and a south pole. The magnetic lines of force extend across the opening between the poles from north to south. Armature. When current goes through the armature, it becomes an electromagnet. The armature, cylindrical in shape, is linked to a drive shaft in order to drive the load. The armature rotates in the magnetic field established by the poles, until the north and south poles of the magnets change location with respect to the armature. Once this happens, the current is reversed to switch the south and north poles of the armature. Commutator. This component is found mainly in DC motors. Its purpose is to overturn the direction of the electric current in the armature. The commutator also helps in the transmission of current between the armature and the power source. 1.4.1 OPERATION OF A DC MOTOR: When a dc motor is subject to dc voltage, the current flows through the armature coil. A wire carrying current also has a magnetic field around it. This magnetic field distorts the parallel magnetic field of stator to produce a force which causes the armature coil to turn. FIG-1.2 operation of motor Each coil of the armature is not only connected to the brushes but the brushes are connected first to one end and then to the other end of the coil. This commutating action is necessary to maintain the same direction of the current flow in the armature coils relative to the magnetic field lines in the field poles. The motor would never turn without commutation. FIG-1.3 cross section diagram of a motor 1.4.2 Types of Excitations There are two basic elements in a DC motor. The way in which these are connected results in various types of DC motors. SHUNT WOUND: The construction and principle of operation of a shunt motor is similar to any DC motor. This type of motor is called shunt because the field is in parallel or shunts the armature. The shunt field is directly connected in parallel with the armature circuit. Shunt windings require large number of turns to produce a strong magnetic field. SERIES WOUND: In a series wound motor, the field is connected in series with the armature. In this type, the speed tends to increase until the back EMF equals the impressed voltage. The EMF also decreases the current in the field and armature. As the field weakens more speed is required to maintain the counter EMF. Thus a series motor is used only where the load is attached e.g. A lift truck, an electric crane. Etc. COMPOUND WOUND: A compound motor has two field windings, the shunt field and series field. The shunt connected in parallel with the armature and the series field connected in series with the armature. The combination of both fields gives double advantages. It has a greater torque than the shunt motor due to the series field and fairly constant speed due to the series field winding. The compound motor has both shunt and series motor characteristics. These will be discussed along with their control techniques in the next chapter. 1.5 TACHOMETER A tachometer is an instrument that measures the rotational speed of the shaft of the motor. It functions in a similar fashion as compared to a speedometer on a car. It tells you the speed of the car. Similarly the tachometer is used to measure the motor speed. In a closed loop control system the information about the instantaneous state of the output is fed back and compared with the input and difference is used to modify the output in such manner as to achieve a desired condition. Similarly a tachometer is coupled to the shaft of the motor. Thus a signal representing the speed of the motor is produced. This signal is fed back to the input where it is compared to the speed command voltage. The error produced is actuated by the speed of the motor. In my designed controller the error actuating and motor control is achieved by programming the microcontroller. It is used to control the rotation of the motor. It senses the input and process it using the program burned in it and gives the required PWM output on the required port pins. This output controls the on/off time of the mosfet and thus controls the motor. This technique and mosfets will be discussed in the next chapter. As long as the speed command voltage is held constant, the motor will run at a proportional constant speed regardless of the mechanical load. The set speed control gives a dc voltage input, for example 12 volts for maximum speed and zero for stationary. This could be a potentiometer providing any voltage in a range from zero to +12 volts. The microcontroller (PIC) amplifies the difference between the two input voltages (tachometer and potentiometer) and the error is actuated. 1.6 MICROCONTROLLER (PIC) The name PIC initially referred to Programmable Interface Controller. Advantages of using PIC over other controlling devices for controlling the DC motor are given below: SPEED The execution of an instruction in PIC IC is very fast (in micro seconds) and can be changed by changing the oscillator frequency. One instruction generally takes 0.2 microseconds. COMPACT: The PIC IC will make the hardware circuitry compact. RISC PROCESSOR The instruction set consists of only 35 instructions. EPROM PROGRAM MEMORY Program can be modified and rewritten very easily. INBUILT HARDWARE SUPPORT Since PIC IC has inbuilt programmable timers, ports and interrupts, no extra hardware is needed. POWERFUL OUTPUT PIN CONTROL Output pins can be driven to high state, using a single instruction. The output pin can drive a load up to 25mA. INBUILT I/O PORTS EXPANSIONS This reduces the extra ICs which are needed for port expansion and port can be expanded very easily. INTEGRATION OF OPERATIONAL FEATURES Power on reset and brown/out protection ensures that the chip operates only when the supply voltage is within specification. A watchdog timer resets PIC if the chip ever malfunctions and deviates from its normal operation. The speed of motor is directly proportional to the DC voltage applied across its terminals. Hence, if we control the voltage applied across its terminal we actually control its speed. A PWM (Pulse Width Modulation) wave can be used to control the speed of the motor. Here the average voltage given or the average current flowing through the motor will change depending on the ON and OFF time of the pulses controlling the speed of the motor i.e. The duty cycle of the wave controls motor speed. This wave is generated by the PIC. . CHAPTER 2. 2.1 DC SHUNT MOTOR FIG -2.3 Shunt windings require large number of turns to produce a strong magnetic field. This is because a small gauge wire cannot handle heavy currents. As a result, when voltage is applied, very little current flows through the shunt coil. The interaction of the magnetic fields between the one from armature and the one from shunt coil causes the motor to rotate. The speed can be controlled by varying the field strength or armature voltage. Current is supplied from the stationary housing to the rotating armature through commutator brushes arrangement. As the stator is stationary, power is applied directly to it. 2.1.2 SPEED CONTROL OF A DC SHUNT MOTOR This type of motor runs at a constant speed practically, regardless of the load. It is the type generally used in commercial practice. Speed of the shunt wound motors may be varied in two ways: First, by inserting resistance in series with the armature, thus decreasing speed (FIG ) And second, by inserting resistance in the field circuit. In this case the speed will vary with each change in load. This normally works with any controller setting i.e. it maintains constant speed despite variable load. Therefore, a shunt motor has proved its efficiency in adjustable speed service and loads requiring a low starting torque. 2.2 DC SERIES MOTOR In a series motor, the field winding (shunt field) is connected in series with the armature winding (A) as shown in the figure. The field current is therefore equal to the armature current. Speed is restricted to 5000 RPM It must be avoided to run a series motor with no load because the motor will accelerate uncontrollably. FIG-2.5 V = Supply voltage E = Generated e.m.f I = Supply current RA = Armature resistance RF = Field resistance 2.2.2 SPEED CONTROL OF A DC SERIES MOTOR The speed of a series motor depends almost entirely on the flux. The stronger the field flux, the lower the speed. Likewise, decrease in load current and therefore in field current and field flux causes an increase in speed. This can be achieved by adding a resistor in parallel with the series field winding. This causes the field current to decrease and the flux drops accordingly. This causes the motor speed to increase. The speed can be decreased by adding an external resistor in series with the armature and the field winding. This would cause a reduction in the armature supply voltage causing the motor speed to decrease. 2.3 DC COMPOUND MOTOR A DC compound motor is a combination of shunt and series motor. In a compound motor, the field winding (shunt field) is connected in parallel in series with the armature winding (A). For this reason this motor has a good starting torque and a stable speed. The higher the percentage of compounding (i.e. percentage of field winding connected in series), the higher the starting torque this motor can handle. For example, compounding of 40-50% makes the motor suitable for hoists and cranes, but standard compound motors (12%) are not. There are 2 major types of compound motors. These are given below: Cumulative compound motors Differential compound motors FIF-2.6 CUMULATIVE COMPOUND MOTOR FIG-2.7 DIFFERENTIAL COMPOUND MOTOR 2.3.2 SPEED CONTROL OF A COMPOUND MOTOR The speed of a compound motor can easily be controlled by changing the voltage supply to the motor. A solid state AC variable frequency motor drive can also be used to vary the speed of an AC motor. 2.4 PWM (PULSE WIDTH MODULATION) PWM, or Pulse Width Modulation, is a method of controlling the amount of power to a load without having to dissipate any power in the load driver. Imagine a 10W light bulb load supplied from a battery. In this case the battery supplies 10W of power, and the light bulb converts this 10W into light and heat. No power is lost anywhere else in the circuit. If we wanted to dim the light bulb, so it only absorbed 5W of power, we could place a resistor in series which absorbed 5W and then the light bulb could absorb the other 5W. This would work, but the power dissipated in the resistor not only makes it get very hot, but is wasted. The battery is still supplying 10W. An alternative way is to switch the light bulb on and off very quickly so that it is only on for half of the time. Then the average power taken by the light bulb is still only 5W, and the average power supplied by the battery is only supplying 5W also. If we wanted the bulb to take 6W, we could leave the switch on for a little longer than the time it was off, then a little more average power will be delivered to the bulb. This on-off switching is called PWM. The amount of power delivered to the load is proportional to the percentage of time that the load is switched on. Pulse-width modulation (PWM) or duty cycle variations are commonly used in speed control of dc motor. The duty cycle is defined as the percentage of digital high to digital low and digital high pulse-width during a PWM period. Thus by varying the pulse width, we can vary the average voltage across a DC motor and hence its speed In my presented controller design the PWM (Pulse Width Modulation) function of PIC is used for the electric current control to drive a motor. PWM can change the duty of the pulse to output into CCP1 by the data. The duty of the pulse of CCP1 is controlled in the voltage (the control voltage). When the control voltage is higher than the regulation value, the H level time of the CCP1 pulse is made long and the number of rotations of the motor is lowered. When the control voltage is lower than the regulation value, the H level time of the CCP1 pulse is made short and the number of rotations of the motor is raised. This mechanism will be discussed and elaborated in the next chapter. 2.5 MOSFETS The speed controller works by varying the average voltage sent to the motor. Imagine a light bulb with a switch. When you close the switch, the bulb goes on and is at full brightness, say 100 Watts. When you open the switch it goes off (0 Watts). Now if you close the switch for a fraction of a second, and then open it for the same amount of time, the filament wont have time to cool down and heat up, and you will just get an average glow of 50 Watts. This is how lamp dimmers work, and the same principle is used by speed controllers to drive a motor. When the switch is closed, the motor sees 12 Volts, and when it is open it sees 0 Volts. If the switch is open for the same amount of time as it is closed, the motor will see an average of 6 Volts, and will run more slowly accordingly. As the amount of time that the voltage is on increases compared with the amount of time that it is off, the average speed of the motor increases. This on-off switching is performed by power MOSFETs. A MOSFET (Metal-Oxide-Semiconductor Field Effect Transistor) is a device that can turn very large currents on and off under the control of a low signal level voltage 2.5.1 TYPES OF MOSFETS. There are NPN type and PNP type as the semiconductor part. When no voltage is applied no electric current flows between the drain and the source. NPN type is called N-channel and PNP type is called P channel. An oxide film is put to the semiconductor of NPN or PNP and metal is put onto it as the gate. In case of NPN, the part of N is a source pole and a drain pole. In case of PNP, the part of P is the polar side. When positive voltage is applied to the gate of the N-channel MOS FET, the electrons of N-channel of source and drain are attracted to the gate and go into the P-channel semiconductor among both. With the movement of these electrons, it conditions itself like spans a bridge for electrons between drain and source. The size of this bridge is controlled by the voltage to apply to the gate. . This type (N CHANNEL) of mosfet is used in the presented controller. FIG 2.8 In case of P-channel MOS FET, the voltage is opposite but does similar operation. When negative voltage is applied to the gate of P-channel MOS FET, the holes of P-channel of source and drain are attracted to the gate and go into the N-channel semiconductor among both. With the movement of these holes, a bridge for holes is spanned and the electric current flows between drain and source. Transistor controls an output current by the input current. However, in case of FET, it controls an output current by input voltage (Electric field). The input current doesnt flow. To handle a MOS FET, needs attention because the oxidation insulation film is thin. This film is prone to the high voltage of the static electricity and so on. CHAPTER 3 The highlighted part in the figure represents the shaft which links the motor and the tachometer. The speed of the motor is directly proportional to the frequency of the tachometer. The dc voltage input is provided by the potentiometer. The microcontroller operates on a dc voltage. The output from the tachometer is a sine wave which has to be rectified in order to operate the pic. This is achieved using an F/V converter. The converter releases a dc logic signal which operates the pic. CIRCUIT EXPLANATION: The input voltage to the main motor is controlled by a potentiometer. This variable resistor could be adjusted manually to provide a 0-12 v input. This voltage sets the number of rotations of the main motor. The input voltage of PIC becomes low when bringing VR1 close to the side 1 and PIC increases the drive electric current of the motor. That is, the revolution of the motor rises. The input voltage of PIC becomes high when bringing VR1 close to the side 3 and PIC reduces the drive electric current of the motor. That is, the revolution of the motor slows down. Control voltage is defined as the feedback signal which is produced to rectify the error between the desired and controlled speed. This is provided by the tachometer in our case. The output from the tachometer is a sine wave which cannot operate the microcontroller to perform the programmed functions. This is converted to a dc voltage signal compatible with the pic microcontroller. This changed voltage is used to enable the CCP feature of the PIC resulting in motor drive. The CCP feature will be discussed in detail later in the chapter. The control voltage to PIC is thus governed by the fluctuations of the main motor. This control voltage (feedback signal) is directly proportional to the rotational speed of the motor. The PIC microcontroller is the brain of the circuit controlling all actions to be done and the output. PIC controls the electric drive current for the control voltage to become a regulation value. When the revolution of the motor slows down, i.e. control voltage goes down, the drive electric current of the motor is increased and number of rotations is raised. When the control voltage reaches a regulation value, a drive electric current at the point is held. When the number of rotations of the motor is high, i.e. the control voltage is high, the drive electric current of the motor is reduced and number of rotations is lowered D1 is used to protect PIC when the voltage of the detection motor is high. The voltage which is applied to the terminal of PIC is a maximum of +5V. This zener diode prevents the destruction of PIC when the speed detection voltage of the motor exceeds 5V. CCP FEATURE Capture, Compare and Pulse Width Modulation feature is abbreviated to form CCP. Capture This is the function to capture the 16 bits value of timer1 register when an event occurs on pin RC2/CCP1. This can be used for the measurement of the period time of the signal like the frequency counter and so on Compare Generate an interrupt, or change on output pin, when Timer 1 matches a pre-set comparison value PWM Create a re-configurable steady duty cycle square wave output at a user set frequency. The timer resource of the capture and compare is timer1 and the timer resource of PWM is timer2. The following steps should be taken when configuring the CCP module for PWM operation: Set the PWM period by writing to the PR2 register. PWM Period equals [(PR2+1)]*4Tosc*(timer 2 prescale value), and the resultant PWM frequency equals 1/ PWM_Period. Tosc stands for time period of the oscillations. Set the PWM duty cycle by writing to the CCPR1L register and CCP1X and CCP1Y bits of CCP1CON register. Duty Cycle is based on CCPRxL, most significant byte, and CCPxCON, least significant two bits. CCPRxL functions as a comparative value with timer 2 and a scaling factor to determine the number of counts of CCPx. PWM logic remains high, without considering CCPxCON. The two least significant bits, CCPxCON, determine the percentage of the maximum resolution the PWM duty cycle is extended. Make the CCP1 pin an output by clearing the TRISC. Set the TMR2 prescale value and enable Timer2 by writing to T2CON register. Configure the CCP1 module for PWM operation. PWM can change the duty of the pulse to output into CCP1 by the data. When the time period of the H level of the pulse of CCP1 is short, the time of ON (the L level) becomes long in TR2 which implies that the drive electric current of the motor increases. Oppositely, when the H level time of the pulse of CCP1 is long, the ON time of TR2 becomes short and the drive electric current of the motor decreases. The duty of the pulse of CCP1 is controlled by the control voltage (feedback signal) which was taken in with input circuit. When the control voltage is higher than the regulation value, the H level time of the CCP1 pulse is made long and the number of rotations of the motor is lowered. When the control voltage is lower than the regulation value, the H level time of the CCP1 pulse is made short and the number of rotations of the motor is raised. A three terminal regulator is used for getting the operate voltage for pic.

The Problem with 6 Digits Dating
What started of as a noble act of saving some memory space turned out to be a quake, capable of trembling the world to its core. When maiden inventors set the year with two digits instead of four, little did they realize that by 1st January 2000 it would cause arithmetic delinquencies and confuses the entire system. For example, a bank transaction on the 25th of July 1997 would be recorded as 07/25/97. Many software add the value 1900 to the two digits code to calculate the actual year. A credit card charged on 1st of January 2000 would have to bear the interest of 99 years because the transaction date would read 01/01/00. This means the computers assume that the same transaction took place on 01/01/1900. Another major problem with six digits dating occurs when we tend to compare the pre and post ââ¬â 2000 dates. For example, 01/09/99 and 01/01/00, when converted into a simple code they would read 990901 and 000101 respectively. Obviously 990901 is older than 000101, which in reality is not true. As the computers cannot process the current date as year 2000 marches in, it is also unable to calculate the leap year. All years divisible by 4 is considered as a leap year except for centuries. A century will be considered as a leap year only if it is divisible by 400. For example, 1996 is considered as a leap year because it is divisible by 4 (1996 4 = 499) wherelse 1997 is not (1997/4 = 499.25). On the hand the hand, 1900 is not a leap year for it is not divisible by 400 (1900/400=4.75). Year 2000 is a leap year for it is divisible by 400 (2000/400 = 5) (with reference to explanation from: http://www.ast.cam.ac.uk/RGO/leaflets/leapyear/leapyear.html). As we step into the year 2000, existing computers will not be able to differentiate the two digits year anymore. The ââ¬Å"00â⬠date field might be assumed as 1900 instead of 2000. Thus calculations that involve a date would provide wrong answers. On the 1st of January 2000, computers will define this day as 01/01/00 and regards the year as 1900, leaving us 99 years behind time. This will interrupt public services, bank transactions, loan interest calculations and many more, causing formidable loss of billions of dollars. Only a few systems could be spared from the Y2K and it has been estimated that there are 500 billion lines of application code worldwide, with some 85% of which needs to be corrected. Various reports stated that by the turn of the millennium, as much as 50% of all businesses which failed to address the year 2000 challenge would fall apart. Besides being deadly, expensive and extensive, the year 2000 problem affects hardware (BIOS, real-time clocks), embedded firmware, languages and compilers, operating systems, random number generators, database management systems, transaction-processing systems, banking systems, PBX, flight scheduling and any other system that deals with dates. Surfing the net would prove that the Y2K's awareness level is growing with more more sites dedicated to this problem. Managers and IT resources are becoming heavy-hearted thinking about their future as 31st December 1999 rolls in. Knowing that there is going to be an IT disaster does not help much especially when there are few resources to handle the problem. A rough estimation to create solutions for the Y2K issue concentrated on something like US $400 -600 billion dollars worldwide. An additional 200,000 COBOL programmers will also be required. Organizations are not the only ones that are going to suffer from the virulent millennium bug, it can be anyone, even a personal computer user.

I am a very big classroom in a well-known public school. I cater to needs of the kindergarten class of the school, accommodating I think about eighty five children, a big number isnââ¬â¢t it? I understand that I am the best looking room in the school as, the very small children study here. I am very attractively decorated so that the little ones like to come here every day. The room that is me ââ¬â is decorated with beautiful coloured pictures. The walls are a blend of some colours I do not know the names of. The furniture that is placed in the length and breadth of the room consists of small round tables to seat four children on each table, and the chairs are also tiny. That is not all, all the furniture is a mixture of many colours. When the children come inside the class they almost fight to sit on certain chairs. That makes me understand that they like the colours and fight for their favourite colours to sit on. At the top two ends of the length of the classroom there are two bigger tables and full size chairs for the teachers to sit. Since there are so many children there are two teachers while in other classes there is only one each. I am a treat for everyone to see. My pleasure knows no bounds when everyone who comes inside the class, admires me, appreciates my get up and the colours that don me. I have the twin advantage of being the most beautiful room in the school and also having the cutest of children coming to spend their time with me. Thus, my life is full of beauty, colour, noise and laughter and at times of course also crying and howling of the children. At times some new entrants to the school come to me with their mothers and, cry as if they had come to the slaughter house to be butchered. At such moments even by heart cries for the little ones and I wonder why man makes these little children come to study if they do not want to. I of course do not know how important studies are for human children, I only feel sad seeing the children cry. My life is full of a very busy schedule though very interesting. The routine of my daily life is so busy that, I do not get any relief for quite long hours. In the morning as early as 6 a. m.two sweepers come open the lock of my room or rather me, and off they start working on me. They sweep my floor, squab it, dust each and every piece of the furniture in me. Thus, I get alerted as soon the room is unlocked. It is not even 8 a. m. when the little brats start pouring inside my bodyââ¬â¢s doors. At times they enter with so much noise that my whole body feels the rattle of it all. Their movements are so loud that now, I cannot even think of any rest. School bags get flung, tiffin boxes are strewn all about, water bottles are kept just anywhere and there is a lot of commotion all over. Soon the maid enters the room and keeps everything in order and my appearance at once improves and I look tidy and well kept. For these small ones the school hours are just three from, 8 a. m. to 11 a. m. These three hours is my duty time, and just is the time when I also get the dayââ¬â¢s entertainment. Being a classroom for the Kindergarten children I get a great chance of hearing conversations between the teachers and the parents. Since this is the first time their children have entered school, parents devote a lot of time to talking about the school and its standards. At times I find that some parents are just too critical and, inspite of getting all the best in this school they always seem to be unhappy and dissatisfied with something or the other in the school. Such parents keep lecturing about things missing in the classroom, the school or even in the playground. When I hear such complaints, my heart sinks and I wonder if they will allow or not allow their children to come to me any more,. For such conversations I have understood that, these days parents pamper the children too much, and it seems that they can never yes, never be satisfied. I am quite surprised to see the vast difference in opinions. While on the one hand I, and also many parents think that I am very beautiful, well kept, and decorated, others of the same clan are always complaining of many defects in my appearance. This gives me a feeling of depression and I do wonder if I can do anything in the matter. After some thinking bouts, I realize that, I can do nothing to satisfy these unhappy parents. I am just here in the hands of the school authorities and stand here as and how they keep me. My working hours are just six, from 6 a. m. when sweepers enter to say 12 noon when I am locked after all children go. After my duty hours I just relax but also feel lonely. No matter what is said about me, I am thoroughly enjoying my life in the cute company of little children. Their company makes me also feel young though now I am quite old. Every summer vacation I am painted afresh, my furniture is painted, and, I am ready to welcome my little friends, new and old with a new look, new enthusiasm and renewed vigour. I pray that my life is forever allowed to remain so interesting and so relaxed. I just love all the children and teachers who come here to me, to work and play in the restricted area within my four walls.

Law of International Trade Essays
Law of International Trade Essays Law of International Trade Essay Law of International Trade Essay Introduction Coffee Beans that were bought in Sao Paulo. Brazil are to be transported to a terminal based in Durham. England. The entire weight of the Coffee Beans to be shipped is 1500 metric tons. At first. this may look to be an ordinary cargo on the surface. However. when seting into perspective the sum of legalities to be fulfilled and the monolithic measure of beans involved. the dashing nature of the undertaking becomes apparent. Every state has its ain set of curious trade Torahs. These Torahs become more complex and stringent when it comes to International trade. However. while merchandising across boundaries. the local domestic jurisprudence demands to be respected at any cost. An International trade jurisprudence is a combination of the jurisprudence of the land and international Torahs regulating the minutess of goods or services across boundary lines ( Cornell. 2005 ) . Multilateral pacts are besides signed between states to decide differences and efficaciously implement reciprocally consented footings and conditions. This is done to standardise the full procedure and prevent struggles. For case. the Convention on contracts for the International Gross saless of Goods ( CISG ) is one such international trade understanding put away by the UN to regulate International trade operations. The different manners of transit available for transit demand to be considered. maintaining in head a host of factors. This includes guaranting the safe theodolite of the beans at each and every point. right from the topographic point of purchase to the finish terminal. Attempts besides need to be made to do the procedure every bit economical as possible. The decrease in transit charges would interpret to higher degrees of net income. The sharing of the costs involved in transporting the beans should be decently worked out and the determinations should be incorporated into the understanding. The point at which the sellerââ¬â¢s liability ends besides needs to be suitably documented. It is normally indicated by the INCO footings. Although economic system in transit is indispensable. it should non come at the cost of priceless clip. The goods besides need to be transported within a sensible timeframe. The Torahs modulating trade in the going every bit good as finish points need to be decently interpreted. in order to avoid confusion at a ulterior point of clip. This calls for relevant paperwork which would attest the legitimacy of the whole procedure. To get down with. the whole procedure demands to be broken down into different stairss. The purchase of java beans can either be from a maker or a jobber. Relevant cogent evidence of purchase provided should be provided by the marketer. after having the in agreement monetary value. Other export licenses should be purchased. in order to transport them to the terminal in Durham. Then. the purchased beans are moved to a warehouse. Since the purchased goods are rather voluminous and bulky. transporting the goods through best the most cost-efficient solution. However. the goods from the sellerââ¬â¢s premises have to be transported to a warehouse. A warehouse is normally an empty storage with equal installations for traveling goods. It is used by makers. concerns. importers. jobbers. exporters and imposts bureau to intermediately hive away goods. The marketer would hold to advise the purchaser about the estimated clip of reaching. The marketer would besides hold to supply necessary cogent evidence paperss of each phase involved in the passenger car of the goods. A host of disbursals are normally incurred during the passenger car of goods from one state to another. This includes disbursals incurred in Warehouse storage and labor. export packing. burden charges. inland cargo. terminal charges. forwarderââ¬â¢s fee. vas burden charges. charges upon reaching. ocean/ air cargo. strike responsibility. revenue enhancements. imposts and charges upon bringing at the finish. While transporting out International trade. the chief concern is the surety of obtaining payments within an acceptable period of clip. This concern is addressed by the construct of Documentary Credits. Documentary Credit is a system by which the purchaser instructs his bank to pay the marketer. On the footing of client trust. the bank transfers the financess to the sellerââ¬â¢s bank history on the behalf of the purchaser. However. equal paperss in support of the concerned dealing will hold sent from the ship to the sellerââ¬â¢s bank. After verifying these paperss. they are sent to the buyerââ¬â¢s bank for farther processing ( Fraud Aid. 2005 ) . In this agreement. the bank becomes the primary obligator. thereby advancing healthy International trade by extinguishing uncertainties and concerns about payment. The written direction given by the purchaser to his bank is besides normally known as missive of recognition ( L/C ) . The International Chamber of Commerce has defined some internationally recognized trading footings. These footings are otherwise referred to as INCO footings 2000. These trading footings are normally used during the abroad transit of goods. They are used to bespeak whether it is the marketer or purchaser that has to bring forth the needed paperss indispensable for transporting out trade on a planetary graduated table. The INCO footings should be followed by the named topographic point mentioned in the contract ( International Business Institute. 2000 ) . The named topographic point in this instance is Durham. England. These footings are capable of denominating the liabilities every bit good as rights of each party involved. Incoterms 2000 Ex Worksââ¬â¢ refers to type of bringing where the full cost and hazard of transporting the goods from sellerââ¬â¢s premises to the concluding finish is borne by the purchaser. This theoretical account is extremely good to the marketer. since there is no hazard involved. The marketer does non even have to take up the duty of lading the goods from his premises. as the lone duty will be to do goods available. The relevant bill and testimonies mentioned in the contract will besides hold to be provided by the marketer. The short term for Ex Works is EXW. Free Alongside Shipââ¬â¢ transfers the hazard and cost of transit when the marketer transports the goods to the quay. alongside the ship. The abbreviation for Free Alongside Ship is FAS. In Free Carrierââ¬â¢ . the duty of guaranting the safety of the goods ends for the marketer when the goods are handed over to the Carrierââ¬â¢s detention at a reciprocally agreed location. This location is referred to as the named point. In Free On Board. the marketer bears the liability until the goods are put on board the ship at the Port of cargo. The port of cargo is mentioned in the contract. From this point. the hazard transportations to the Buyer. This is normally known as FOB. In Cost A ; Freight ( CFR ) . the marketer ships the goods to the named Port of finish mentioned in the contract. by paying the cargo charges. The purchaser so takes up complete duty when the goods base on balls over the shipââ¬â¢s rail at the Port. The conditions of Cost Insurance A ; Freight are similar to the old 1. However. the Seller has to take the extra duty of paying the insurance premium on the buyerââ¬â¢s behalf. This is denoted by CIF. The marketer has to besides incur disbursals in sing all the hazards until the named finish. in the instance of Carriage A ; Insurance Paid ( CIP ) . When the marketer bears the cargo charges of the goods until they reach the reciprocally agreed location. it is mentioned as Passenger car Paid ( APT ) . Equally shortly as the goods reach the first bearer. it becomes a liability of the purchaser. In Delivery at Frontier ( DAB ) . the marketer bears the charges and liabilities until the goods enter the Frontier. When the goods reach the Customs procedure. it risk transportations to the purchaser. Delivered Duty Paid ( ADP ) is most favourable to the purchaser. since the marketer will bear all charges incurred in presenting the goods to the purchaser. Delivered Duty Unpaid is similar to ADP. with the exclusion of import responsibility and other official import charges that are borne by the purchaser. In Delivered Ex Ship ( DES ) . the duty and cost of reassigning the goods base on ballss from the marketer to the purchaser when the ship transporting the goods reaches the finish port. It will be the buyerââ¬â¢s duty to dispatch the goods. Delivered Ex Quay ( DEQ ) is of two types ; Duty Paid and Duty on Buyers Account. The marketer has the duty to present the goods in the quay of the finish port. Either the purchaser or the sealant takes up the duty of the paying the responsibility. harmonizing to the initial understanding. Farther considerations Many factors have to be considered when it comes to structuring a passenger car contract understanding. There are three signifiers of passenger car ; common passenger car. contract passenger car and private passenger car. Common passenger car is a type of bearer service catering to the general populace to execute common transit services. These services have to be authorized by assorted authorities regulative bureaus. The duties that are charged for the service legitimately demanded locations are held by these bureaus. Contract passenger car involves transit services to an limitless figure of stations. These bureaus besides have to acquire necessary mandate from the same bureaus. Relevant contracts dwelling of inside informations about the minimal rates and charges are filed at different allowing bureaus and. Transcripts of this contract are besides retained at the installations of the shippers every bit good as the bearers. Private passenger car offers transit services to concern endeavors. This service is for meant for makers and distributers that transport their goods in their private vehicles driven by their ain employees. It is besides normally known as shipper-carrier. The distinct needsââ¬â¢ proviso takes attention of separating the different passenger car types. It is really indispensable to separate between a normal contract and a passenger car contract ; failure to carry through this could ensue in several liability issues on both sides. This distinguishable needs proviso helps to separate a passenger car contract from a regular one. This proviso incorporates certain alone footings and conditions including specific demands of a shipper and the duties that need to be satisfied by the contract bearer. Some of the commonly reference distinguishable needs in a passenger car contract understanding are monetary value accommodation clauses. footings of recognition. incidental transit charges. lading transportation charges and specific bringing agendas. However. the shipper should truly consist these alone services if they are mentioned. A certain grade of rationality should be allowed while covering with passenger car contracts. First of all. one has to understand assorted transporting term in order to grok the transportation regulations better. Carrierââ¬â¢ is a term used to mention to the individual who marks the contract of passenger car with a shipper. It is normally the proprietor or charterer who hires a ship to transport their lading. riders or other goods. Shipperââ¬â¢ refers to the individual who pays money to the bearer to transport his goods ( Arnold. 2003 ) . Hence. the term shipperââ¬â¢ may either mention to the purchaser or the marketer of the beans. depending upon the INCO term in usage. Carrier is the company or bureau which undertakes to transport the beans from Brazil to England. The Contract of passenger car will use to understandings mentioned in the measure of ladling or any similar papers that concerns the passenger car of goods by sea. The term goodsââ¬â¢ is used to mention to wares. ware and other articles. However. unrecorded animate beings are non included in the goods class. Goods such as brandy and gun pulverization were classified as unsafe goods. The cogency period of the Contract of passenger car starts from the clip of goods being loaded until they are unloaded from the ship. Hague A ; Hague Visby Rules Hague regulations were framed by the International Convention for the Unification of Certain Rules of Law associating to Bills of Lading and Protocol of Signature. It came into consequence on 25 August 1924 in Brussels. It was an attempt to represent a minimal compulsory liability for bearers. since most of them were hedging the liability due to loss or harm of lading. Harmonizing to the Organisation for Economic Co-operation and Development ( OECD ) . this was a move by the International community to manufacture a just system for the shipper every bit good as the bearer. Even today. these regulations act as the foundation for bordering marine trading Torahs for a bulk of the states around the universe. Harmonizing to Hague Rules. the bearer will be apt to bear the cost of damaged or lost goods merely if the shipper is able to turn out that the shipperââ¬â¢s deficiency or absence of diligence. However. the bearer would non be held apt if the ship was unseaworthy. The bearer will besides lose the liability to counterbalance for the goods. when the harm is caused by a natural catastrophe termed as Act of Godââ¬â¢ or a fire accident which is caused to due to any ground other than a mistake in the bearer vas. The bearer will besides non be apt for amendss caused due to the act of terrorists. war or and other anti-social elements like plagiarists. The bearer would non be responsible for a hold in the bringing of goods. if the hold was caused due to an exigency state of affairs like lockouts. quarantine operations or public work stoppages. The shipper would non be able to claim amendss from the bearer. even in the event of disregard of the responsibility by the employees of the ship. Therefore. this enabled the bearer to acquire away with liabilities originating as a consequence of mistakes made by the people working on board such as seamans and the carrierââ¬â¢s working staff. if the bearer was in a place to turn out that the ship was seaworthy and adequately and suitably manned ( Admiralty Law Guide. 2006 ) . Since this proviso lets bearers to acquire off scot-free. it has posed a serious struggle in equilibrating liabilities between the bearer and shipper. Transportation system of goods involves two chief types of contracts. They are Carriage Contract Agreement and Bill of Lading Contract. Passenger car Contract Agreements are normally signed when long cargos are involved. It serves as a go oning contract that stands for the safe bringing of goods to promised finish. It normally covers multiple cargos that are necessary to transport out a long cargo procedure. The complete cargo procedure may affect other manners of transit such as land and air cargo. However. passenger car contract can non function as a reception of ware. The Bill of Lading is issued by the bearer as a cogent evidence of having the goods and serves as reception of ware. A Bill of Lading is an understanding for a individual cargo procedure which may be a portion of a long procedure. In the practical sense. it is a list of outgos incurred towards lading goods into a vas. It is governed by all the footings and conditions mentioned in the Carriage Contract. It besides acts as certification that verifies the genuineness of the laden goods. Further. it indicates whether the received goods were in good status or non. Depending upon status of the goods and packaging. the Bill of Lading is classified as Clean or Foul Bill of Lading. It besides is farther cogent evidence of the being of a Carriage Contract ( Wikipedia. 2006 ) . However. the Bill of ladling and Carriage Contract are wholly different entities and they serve different intents. Hence. the Bill of Ladling can non be used as a Contract Carriage and frailty versa. There are three types of measure of ladling ; consecutive measure of ladling. order measure of ladling and bearer measure of cargo. In consecutive measure of ladling. the consignee can claim amendss from the consignor when the goods are non delivered on clip due to defaulting or carelessness of the consignor. This measure of ladling is non-negotiable. In order measure of ladling. the consignee can obtain bringing of goods if the consignee provides a measure and grounds demoing the consignerââ¬â¢s involvement to reassign. This measure of cargo is negotiable. In bearer measure of ladling. any individual keeping the measure of landing is entitled to have the goods. When the consignor does non advert the consigneeââ¬â¢s name. it becomes a carrier measure and can be negotiated. Goods that are issued with a negotiable measure of ladling can be received merely if the original paperss are presented at the clip of bringing. However. the hurrying of trade and theodolite operations has given manner to the issue of non-negotiable paperss for goods. which enables the consignor to have the goods by merely showing the non-negotiable measure of ladling ( Forwarder Law. 2005 ) . Some of the standard duties that have to be fulfilled by the consignor include supplying the bearer with consigneeââ¬â¢s name and reference and finish of the passenger car. The nature. weight. volume and the measure of the goods to be shipped are besides to be clearly stated. Even the wadding and wrapper manner. figure of bundles and any other inside informations needed to place the goods need to be provided by the consignor. The consigner would be held be responsible for any amendss. in the event of false or deficient inside informations being provided. Harmonizing to Article 283 of the Carriage of Goods by Sea Act ( CGSA ) ( 1924 ) . the Bill of Lading can be issued either in the name of a peculiar individual or the carrier. It normally consists of the following inside informations. 1 ) Date of publishing the measure. 2 ) Venue where the measure was signed and brought to consequence. 3 ) Topographic point of going and finish. 4 ) Names and references of the consigner. consignee. bearer and the passenger car committee agent. 5 ) The value and designation inside informations of the shipped points. 6 ) Date of transportation. 7 ) Freight and other disbursals with an indicant of whether they are collectible by the consigner or the consignee. 8 ) The conditions refering to the burden and unloading. type of conveyance agencies required to be used for passenger car. the path to be followed. a finding of the duty and any other particular conditions which may be included in a passenger car contract. In add-on to the measure of ladling. the bearer besides issues a non-negotiable reception called bill of lading which proves to be utile in a state of affairs when the goods arrive before the dealing paperss. It is besides issued when the consignee and the consignor is the same individual ( Evans. 2001 ) . This option can be chosen when the consignor decides to cut down paperwork. A shipââ¬â¢s bringing order is another papers that undertakes to transport goods by sea. The commissariats for this papers are provided by the CGSA ( 1992 ) . However. this papers can neither replace a bill of lading nor a measure of cargo. Harmonizing to Article 284 of the CGSA ( 1924 ) . the bearer would be required to publish a measure of ladling to the consignor. Alternatively. the bearer can besides give a reception adverting the inside informations of the goods carried and day of the month of cargo to the consignor. The consignor would be required to present the goods to be shipped at the carrierââ¬â¢s premises. The consignor should besides bring forth relevant papers deemed necessary for transporting. The consignor will be held responsible for any liability arising as a consequence of inaccurate or uncomplete information in the paperss provided. Harmonizing to Article 288 of the CGSA ( 1924 ) . Since the bearer possesses the right to analyze the packaged goods and the criterion of packing before the passenger car. the harm of goods originating due to improper packaging is non wholly borne by the consignor ; the liability is shared with the bearer. Harmonizing to Article 289 of the same Act. the initial scrutiny of the goods would necessitate the presence of the consignor. if gap of packaging is involved. If the consignor is absent during the review procedure. the scrutiny would come on and scrutiny costs would be levied from the consignor. If the bearer finds the goods to be unsuitable for theodolite. the consignor would be informed about the same. Such goods would be shipped by the bearer merely if the consignor bears the liability of harm of goods and the consignerââ¬â¢s consent about the same is incorporated into the Bill of Lading. Cargo Insurance compensates the shipper with losingss caused due to fire. loss of lading and harm. However. losingss that can be recovered from the bearer will non be compensated by Insurance Company. It is besides popularly known as Marine insurance. It is farther classified into Inland and Ocean Marine Insurance. Inland Marine Insurance is issued for goods that are transported without the affecting any signifier sea conveyance and Ocean Marine Insurance is meant for goods that are shipped through waterways. The three pillars of Marine Insurance are insurable involvement. utmost good religion. and insurance ( Export 911 ) . Marine Insurance is non compulsory. unless it is mentioned so in the understanding. The cogent evidence of Insurance is provided by the Insurance policy duly signed by the authorization of the Insurance Company. Generally. the insurance would cover the loss or harm of java beans under normal fortunes. However. the insurance would go nothingness when the shipper tries to or succeeds in doing knowing harm. When the loss of java beans is meager or caused as a consequence of improper packaging. the insurance would non cover the loss. Harmonizing to Article 292 of the CGSA ( 1924 ) . the bearer is obliged to go in the reciprocally agreed upon path mentioned in the understanding. However. the bearer is expected to take the shortest path if a path is non mentioned in the understanding. However. the bearer can alter class if any ineluctable state of affairs arises and the bearer would non be held apt for any loss caused to the consignor due to the late bringing of goods. provided a echt ground is established. The goods being transported by the bearer should be decently safeguarded. The costs incurred in accomplishing this aim. such as repackaging charges are entirely borne by the bearer. However. this does non connote taking extra attention of the goods being transported. For case. when animate beings are being shipped. the bearer will non be responsible for keeping the wellness of the animate being by supplying nutrient and H2O. The same status will stand good while transporting workss every bit good. However. the bearer would hold to take up such duties. if such conditions regulating the wellbeing of workss and animate being are incorporated in the understanding By and large. the bearer will hold the duty to dispatch the goods from the ship and bear the charges incurred towards it. In the event of the understanding non necessitating the bringing of the shipped point to the consigneeââ¬â¢s installation. so the consignee would hold to have the same on a peculiar day of the month fixed by the bearer. If the consignee fails to make so. so s/he would hold to bear the charges incurred by the bearer for hive awaying the shipped point. However. the consignee has the right to analyze the contents before admiting the reception and decline the same. if the bearer is non co-operating. The following protocol towards the emancipation of the shippers came in the signifier of the Brussels protocol in 1968. It was responsible for inculcating an of import clause called the container clauseââ¬â¢ . It enabled shippers to claim the compensation for each container specified in the Bill of Lading ( Admiralty Law. 2005 ) . As a consequence. this liability system came to be known as the Hague-Visby Rules. An extra protocol was added in 1979 to heighten and revise the regulations. However. neither of two auxiliary protocols of the Hague regulations was able to efficaciously modify the basic liability commissariats. Hamburg Rules The Hamburg regulations were enforced at the United Nations Convention on the Carriage of Goods by Sea held in Hamburg on 30 March 1978. The main aim was to implement a system that would portion the liabilities and duties between shipper and bearer in fairer mode. However. it was merely able to mildly travel the liabilities to the bearer. In add-on to the footings bearer. shipper. goods and ship. a term called Actual carrierââ¬â¢ is defined by the Hamburg regulations. It refers to a individual or an bureau to which the bearer hands over the complete or partial duty of transporting the goods. The clip period for claiming the liabilities caused by the bearer is besides specified by the Hamburg regulations. The shipper can action the bearer for any liabilities with a two twelvemonth clip period from the day of the month of bringing of the goods. This period can be extended by publishing appropriate legal declarations. However. this clip period gets reduced to 90 yearss. in the instance of a 2nd claim after the finding of fact is reached for the first claim. First of all. a written ailment has to be instituted to the bearer within the following on the job twenty-four hours. in the instance of evident harm or loss. However. in the instance of harm or loss non being apparent. the shipper would hold to register a written ailment to the bearer within 15 yearss of having the goods. In order to be in a place to claim amendss due to detain. the bearer would hold to give a compliant to the shipper within 60 yearss of the bringing. The ailment can be sent to the bearer in authorship or via telegraph. Adequate installations will besides hold provided by both parties to inspect and clear up these claims. If the shipper fails to fulfill any of the aforesaid conditions. he or she will non be able to claim amendss from the bearer. The Hamburg regulations besides specify the bounds for liability compensation. The compensation for the liabilities originating as a consequence of harm or loss can non transcend an sum more than 2. 5 units of history per kg or 835 units of history per bundle. This unit is quantified by the International Monetary Fund as a consequence of a Particular Drawing Right. If the shipperââ¬â¢s State is a member of the International Monetary Fund. so the units would be changed into the Stateââ¬â¢s currency on the judgement twenty-four hours. If the shipperââ¬â¢s State is non a member of the International Monetary Fund. the units would be converted harmonizing to the Stateââ¬â¢s local Torahs. The liabilities for hold in the bringing of goods should non be more than the entire cargo payable ; it can be up to two and a half times the cargo payable for the goods that are delayed. under the contract of passenger car. Arbitrations A ; Disputes The arbitration of these claims and general differences would usually take topographic point in a locale of the claimerââ¬â¢s penchant. However. the topographic point should be with in conformity to the judicial admissions mentioned. It should non be a topographic point outside the State where the defendantââ¬â¢s concern or abode is located. It can besides take topographic point in a State where the contract was signed or at the topographic point of lading or droping the goods. Judicial action may besides be taken against the bearer in the same topographic points mentioned above. It is better to see the java beans before they are to be shipped onboard a vas. due to the hazards involved in transit. Since the bearers have merely restricted restrictions. it does do sense to obtain insurance. Most bearers transporting from Sao Paulo to Durham. for case Xiameterââ¬â¢ ( 2006 ) follows Passenger car and Insurance Paid ( CIP ) bringing. Therefore. it is better to transport the java beans through a reputed bearer. in order to understate hazards and finish the transportation within a coveted period of clip.
