Hell Is Other People Essay Example for Free

Hell Is Other People Essay He then shouts that they should have at least allowed him his â€Å"damn toothbrush! † The valet is further amused by this outburst, pointing out that every single â€Å"guest† inquires about the torture chamber, and then once they’ve gotten over the initial shock, they start asking for their toothbrushes and what-not. He assures Garcin that he’ll have no need for his toothbrush here, nor sleep, and advises him to forego his â€Å"sense of human dignity†. While trying to come to terms with his situation, Garcin is disturbed by the valet’s lidless eyes and parallels his perpetual sight to his own perpetual consciousness. So that’s the idea, I am to live without eyelids†¦. No eyelids, no sleep; it follows, doesn’t it? I shall never sleep again. But then how shall I endure my own company? † (After rereading the play for a second time, this seems the most ironic bit because Garcin is Liedtke 2 unaware at this point that this room IS his torture chamber, and the other occupants are his torturers, and there will be no escaping them; not even in sleep. ) When left alone, Garcin quickly grows impatient and begins repeatedly ringing the bell which is supposedly meant to summon the valet. However, it doesn’t seem to be orking so he gives up. The door then opens and the valet is accompanied this time by a woman named Inez. She observes Garcin and is silent when the valet asks if she has any questions. When he exits, she immediately demands from Garcin the whereabouts of someone named Florence, but he has no idea what she’s talking about. Inez assumes Garcin is her torturer and when he asks why she thinks that, she replies that torturers often look frightened. He laughs at this, for who have torturers to be frightened of? Inez replies, â€Å"Laugh away, but I know what I’m talking about. I’ve often watched my own face in the glass. † Garcin perceives her hostility but attempts to get along with Inez. He says it’s obvious she doesn’t want him near her and that’s good because he himself would rather be alone anyways. â€Å"To think things through, you know; to set my life in order, and one does that better by oneself. †

Relationship Between Self Confidence Academic Performance

Relationship Between Self Confidence Academic Performance RESEARCH PROPOSAL Title: The Relationship between Students’ Self Confidence and Learning Achievements in Descriptive Writing of the Tenth Grade of SMAN 41 Jakarta, 2013/2014 Academic Year. The Background of The Research Language is a medium used by people to communicate with others. Lock states that language is a medium of human to communicate that including of words either spoken or written.[1] Through the language, people can easily share their ideas, opinions, and feelings to others, either in spoken or written expression. English is the language that is used by almost people in the world. Rose assumed that international experts calculated that about 400 million people use English as a second language.[2] Therefore, English is the most dominant language used by people in the world. In Indonesia, one of the goals in teaching English is developing students’ communication skill by using English covering four skills: listening, speaking, reading, and writing. These four language skills have to be mastered by the students. In other words, learning English is aimed to make students to be able to use English in communication. Among the four skills, writing is viewed as the most difficult skill to be learned. According to Gorrel and Laird, â€Å"Writing requires thinking, and thinking is always complicated and hard.†[3] Therefore, it is clear that writing needs hard thinking in producing words, sentences, paragraphs and arranging them into a good sequence. In fact, the difficulties of writing also happened when the writer was doing training (PPL) in 41 Senior High School Jakarta. There are some factors that make writing becomes difficult for students. The psychology of the students can also influence the result of their learning achievement in writing. From the explanation above, the writer is interested in doing research to analyze the relationship between students’ self-confidence and learning achievements in descriptive writing of the tenth grade of SMAN 41 Jakarta. Therefore, the result of the research can be informed to the teacher as references in his/her teaching, what should be done in the future. The Scope of the Research In this research, the writer limits the analysis into the relationship between self-confidence and learning achievement’s students in writing especially in descriptive writing. The writer wants to make the questioner and written task form at tenth grade students of SMAN 41 Jakarta. The Problem of the Research Based on the explanation above, the writer formulates the problem as follows â€Å"Is there any significant relationship between students’ self-confidence and learning achievement in descriptive writing of the tenth grade of SMAN 41 Jakarta?† The Objective of the Research The objectives of this research is to find out the empirical data weather there is the significant relationship between students’ self-confidence and learning achievement in descriptive writing of the tenth grade of SMAN 41 Jakarta. Theoretical Framework Self-Confidence The Understanding of Self-Confidence Self-confidence is important for everyone, especially for students. According to Rakhmat, self-confidence is belief about ability himself/herself.[4] The key terms are belief, and himself/herself. Belief means the person has a faith about their ability. Himself/herself means being independent. It means self-confidence is something that is owned by people, and it makes them to believe their own ability. Rodgers in Koswara added self-confidence is the ability to make decisions and judgments without depending on others (independent).[5] The key terms is without depending on others. It means self-confidence is able to make decisions by their own selves. Hakim states, â€Å"Kepercayaan diri adalah suatu keyakinan seseorang terhadap segala aspek kelebihan yang dimilikinya dan keyakinan tersebut membuatnya merasa mampu untuk bisa mencapai berbagai tujuan di dalam hidupnya.†[6] In other words self-confidence is someone’s belief about all aspects that owned by themselves, and that belief makes them for being able to achieve something in their live. The key term is someone’s belief. Someone’s belief refers to someone who believes about their knowledge which then makes them to feel like they can do anything. It can be inferred that self-confidence is something that has someone about their competence which then makes them to feel like they can do anything. From those statements above, it can be concluded that self-confidence is something that someone has already had, and it seems like they can do anything while they have it without relying on others. The Characteristics of Self-Confidence Fatimah suggests some characteristics of self-confidence, there are:[7] Believe in the ability or competence of self, then not need praise, recognition, acceptance or respect from others. Not to be motivated to show the conformist attitude in order to be accepted by others. Dare to accept and face the rejection of others, dare to be yourself. Have a good self-control. Have a positive outlook about themselves, other people, and situations outside of them. Have a realistic expectations of themselves, so that when the expectations was realized, they were still able to see the positive side of themselves and the situation. Moreover, the characteristics of individuals who have self-confidence according to Hakim, they are:[8] Poised in doing something. Have the potential and ability of adequate. Be able to neutralize the tensions that arise in certain situations. Be able to adapt and communicate. Have the mental and physical condition of supporting the appearance. Have the sufficient intelligence. Have the sufficient level of formal education. Have the skills and other skills that support the life. Have the ability to socialize. Have the background of good family education. Have the life experience that forges mental and tenacity on variety of situations. Have the positive attitude in the face of problems. From those characteristics above, the students or individuals that have self-confidence are believe in the competence of self, dare to be yourself, have a good self-control, poised in doing something, be able to adapt and communicate, have the sufficient intelligence, have the ability to socialize, and have the positive attitude in the face of problems. Learning Achievement The Understanding of Learning According to Arthur in Syaiful defines that learning is a modification of behavior through experience and training.[9] The key term is modification of behavior. It means learning is a process that can change the behavior of someone through training and practicing. The second statement from Brown, â€Å"learning is acquiring or getting of knowledge of a subject or a skill by study, experience, or instruction[10]†. It means learning is a process to get the knowledge by someone through study, experience, or instruction. The third definition comes from Good and Brophy in Purwanto, â€Å"Learning is the development of new associations as a result of experience.†[11] The key words are the development, and result of experience. The development refers to the process of the increasing knowledge from not knowing anything to know anything. Result of experience refers to something that the students face when they get the knowledge while they receive it. It can be inferred that learning is the process of getting the new knowledge when they study. From those definitions above, it can be concluded that learning is a process to get the knowledge or skill by studying or practicing. Moreover, it can change someone’s behavior. The Understanding of Achievement Soeito stated that achievement can be formulated as a relatively change of behavior as a result of experience in the past.[12] The key term is change of behavior. Change of behavior means the behavior of someone to be better. It can be summarized that achievement is something that can make the behavior of someone to be better as a result of their experienced. Travers added that achievement is the result of what an individual has learned from some educational experiences.[13] The key term is the result. The result means something which has been reached as an efforts. It can be summarized that achievement is something which has been reached as an efforts. Djamarah defined that achievement is the result of an activity that has been done, created, either individually or in a group.[14] The key term is has been done. Has been done means after the learning process. It can be inferred that achievement is the good result of an activity that has already done after the learning process by someone or in a group. From those definition above the writer concluded that achievement is something that individual earned after giving effort during the activity and it can also change the individual’s behavior. The Understanding of Learning Achievement By determining the previous description about learning and achievement. The writer concludes that learning achievement is something that individual earned after giving effort during the learning process, and it can also change the individual’s behavior. Writing The Understanding of Writing Writing is one kind of media that is used to communicate which is visible. Abrams states, â€Å"Writing is a visual form of communication, either printed in hard-copy or in electronic form.†[15] The key term is visual form; it means the writing is something that can be seen by the reader. Gould states, â€Å"†¦writing is not speech; it is careful arrangement of words on a page which has its own idioms and format and does not transcribe the informalities of speech performance.† The key terms are on a page, and format. On a page means the ideas that laid on a surface of paper. Format means the rules in writing. Therefore, it means writing are ideas that put on a page of paper which has the rules in writing. From two definitions above, it can be inferred from the first statement that writing is something which visible to the reader. While the second statement from Gould completes the first statement, writing is not speech which is arrangement of words on a page of paper that has the rules in making writing. The third statement comes from Yule; he states that â€Å"†¦writing as the symbolic representation of language through the use of graphic signs.†[16] The key terms are symbolic representation, and graphic signs. Symbolic representation means symbols which has the meaning. Graphic signs means the writing that made by people on a papers or any surface. It means writing is one of kinds of media which translated into meaningful symbol or letters on papers or any surface can be written upon. From the statements above, the writer concluded that the writing is ideas whose forms are using symbols. They are put on a page of paper that can be seen and have clear formats. Types of Writing According to Wishon and Burks there are four types of writing; there are Narration, Description, Expository, and Argumentation. Narration Narration is the form of writing used to relate the story of acts or events. Narration places occurrences in time and tells what happened according to natural time sequence. Types of narration include novels, short stories and news stories, as well as a large part of our everyday social interchange in the form of letters and conversation. Description Description reproduces the way things look, smell, taste, feel, or sound; it is may also evoke mood, such as happiness, loneliness or fear. It is used to visual image of people, places, even of units of time-days, times of day of the seasons. It may be used also to describe more than the outward appearance of people. It may tell about their traits character or personality. Exposition Exposition is used in giving information, making explanation, and interpreting meanings. It includes editorials, essays, informative and instructional material. Used in combination with narrative, exposition supports and illustrates. Used apart of narrative, it stands alone as an essay. Used alone or with narrative, exposition may be developed in a number of ways. Argumentation Argumentation is used in persuading and convincing. It is closely related to exposition and is often found combined with it. Argumentation is used to make a case or to prove or disapprove a statement of proposition.[17] From those types, the writer would focus on descriptive writing. Descriptive Writing The Understanding of Description Oshima and Hogue stated, â€Å"Descriptive writing appeals to the senses, so it tells how something looks, feels, smells, tastes, and/or sound.†[18] The key words are tells something looks, feels, smells, tastes, and sound. It means telling the readers about the characteristics and physical appearances of something. In other words, descriptive writing is telling the readers about something in particular by mentioning the characteristic and physical appearance. Similar with Oshima and Hogue, Wishon states, â€Å"Description gives sense impressions the feel, sound, taste, smell, and look of things.†[19] The key terms are gives impressions the feel, sound, taste, smell, and look of things. It means description telling the impressions of how something looks like. In other words description is describing of how something looks like. Trimmer assumed, â€Å"Description is a strategy for presenting a verbal portrait of person, place, or thing.†[20] The key terms are presenting a person, place, and thing. It means description is a composition that presents about person, place, or thing to others people. It can be inferred that writing is presenting about person, place, and thing. From those definitions above, the writer concluded that description is a way to describe the person, place, and thing about their physical appearances and characteristics that can be looked, felt, smelled, sound, and tasted. The Generic Structure Of Description According to Doddy et al, the generic structures of description are: Identification: Identifies phenomenon to describe. It means in this paragraph to describe about physical appearances. Description: Describe parts, qualities, characters. It means in this paragraph to describe about characteristic of the object and the detail information.[21] Research Methodology The Time and Location of the Research The research will be conducted in SMAN 41 Jakarta, 2013/2014 Academic Year on ________ 2014. The Population and Sample of the Research The population respondents will be taken from the students in tenth grade at SMAN 41 Jakarta, 2013 / 2014 Academic Year.

Introduction To What Is A Hammer Mill Engineering Essay

Introduction To What Is A Hammer Mill Engineering Essay It is a machine used to shred material into fine particles (size reduction). They have many sorts of applications in many industries, including: Milling grain, Ethanol plants (corn), Grinding used shipping pallets for mulch, Sawmills, size reduction of trim scrap and planer shavings into boiler fuel or mulch, A farm machine, which mills grain into coarse flour to be fed to livestock. Operation The principle of hammermill is straightforward. A hammermill is a steel drum containing a vertical or horizontal rotating shaft or drum on which hammers are mounted. The hammers are free to swing on the ends of the cross, or fixed to the central rotor. The rotor is spun at a high speed inside the drum while material is fed into a feed hopper. The material is impacted by the hammer bars and is thereby shredded and expelled through screens in the drum of a selected size. Hammer mill apple shredder for juicing. Small grain hammermills are operated on household current. Large automobile shredders could use one or more 2000 horsepower (1.5 MW) diesel engines to power the hammermill. The Screenless hammer mill uses air flow to separate small particles from larger ones. It is designed to be more reliable, much cheaper more energy efficient than regular hammermills. In the feed processing process there may be a number of ingredients that require some form of processing. These include coarse cereal grains, corn that requires particle size reduction which will improve the ingredient performance increase the nutritive value. One of the methods to achieve this particle size reduction is using hammer-mills. Both hammering and rolling can achieve the desired result of achieving adequately ground ingredients, but other factors also need to be looked at before choosing the suitable method to grind. Excessive size reduction can lead to wasted electrical energy, unnecessary wear on mechanical equipment and possible digestive problems in livestock and poultry. For more in depth information regarding what actually occurs to the ingredients during size reduction please refer to this link: particle size reduction.    Mechanism of action: Hammer mills reduce the particle size of materials by impacting a slow moving target, such as a cereal grain, with a rapidly moving hammer. The target has low kinetic energy, whereas the hammer has high kinetic energy. The transfer of energy resulting from the collision fractures the grain into many pieces. Since impact is the primary force used in a Hammer mill to reduce the size of the particles, so, whatever increases the chance of a collision between a hammer and a target, increases the magnitude of the collision, would be an enhancer to particle size reduction. Particles produced using a hammermill are spherical in shape with a polished surface. A wide variation in the particle size distribution would occur where there will be some large-sized and many small-sized particles. Advantages: being to produce a wide range of particle sizes suitable for friable material and fiber easy to use lower cost when compared with a roller mill easy to maintain particles produced are spherical, with a surface that appears polished. Disadvantages: Less energy efficient than roller mill May generate heat so considered as a source of energy loss. Greater particle size variability (less uniform) Noisy generate dust pollution General Design The major components of these hammermills, include: A delivery device: used to introduce the material to be ground into the path of the hammers. A rotor comprised of a series of machined disks mounted on the horizontal shaft performs this task. Free-swinging hammers that are suspended from rods running parallel to the shaft and through the rotor disks. The hammers carry out the function of smashing the ingredients in order to reduce their particle size. A perforated screen and either gravity- or air-assisted removal of ground product. Acts to screen the particle size of the hammer mill to ensure particles meet a specified maximum mesh size. Feeder design Materials are introduced into the paths of the hammers by a variable speed vein feeder. This type of feeder can have its motor slaved by a programmable controller to the main drive motor of the hammer mill. The operational speed of the feeder is controlled to maintain optimum amperage loading of the main motor. Hammer design and configuration The design is determined by operating parameters such as rotor speed, motor horsepower, open area in the screen. Optimal hammer design provides maximum contact with the feed ingredient. Hammer mills in which the rotor speed is approximately 1,800 rpm, should be using hammers which are around 25cm (~ 10 inches) long, 6.35cm (~2.5 inches) wide, 6.4mm (0.25 inches) thick. A rotor speed of about 3,600 rpm, hammers should be 15 to 20 cm (~ 6-8 inches long, 5 cm (~ 2 inches) wide, 6.4 mm (0.25 inches) thick. The number of hammers used for a hammer mill of 1,800 rpm, should be 1 for every 2.5 to 3.5 horsepower, and for 3,600 rpm, one for every 1 to 2 horsepower. Hammers should be balanced on the rods so that they wonà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢t trail one another. The distance between hammer and screen should be 12 to 14 mm (~ 1/2 inch) for size reduction of cereal grains. The velocity is important for proper size reduction. Tip speed is the speed of the hammer at its furthest edge(tip) from the rotor, and is calculated by : Range of tip speeds seen in hammermills is commonly in the range between 5,000 and 7,000 m/min (~ 16,000 and 23,000 feet per minute). When the tip speeds exceed 23,000 feet per minute, consideration must be given to the design of the hammer mill, the materials used, and the fabrication of components. Changing the rotational speed of the drive source is not a recommended method of increasing hammer speed in excess of 23,000 feet per minute. The primary force used in hammermill is the impact, which increases the chance of a collision between a hammer and a target provides an advantage in particle size reduction. The magnitude of the collision is increased by increasing the speed of the hammers. Screen Design The amount of open area in a hammer mill screen controls the particle size and grinding efficiency. The screen must be designed to provide the greatest amount of open area. Recommended ratio for grains would be 55 cm2 (~ 8-9 inches square) per horsepower (Bliss, 1990). The removal of sized material from a hammermill is a critical design feature. Proper output of material affects not only the efficiency of operation, but also particle size. When the correct ratio of screen area to horsepower is used and proper distance between hammers and screen face is maintained. Excessive size reduction is anti-productive. Energy is wasted in the heat production, throughput is restricted, resulting in the particles becoming too small. Most newer hammermills are equipped with an air-assist system that draws air into the hammer mill with the product to be ground. Systems are designed to provide reduced pressure on the exit side of the screen to disrupt the fluidized bed of material on the face of the screen, thus allowing particles to exit through screen holes. Some full circle hammer mills are designed so the screen is in two pieces. It is possible to use a larger hole size on the upward arc of the hammers to further reduce the amount of material on the face of the screen.    Hammer Mill Perforated Screens Hammer mills screens are used inside a hammer mill to seperate particle sizes. Particle of small diameter that has been grinded by the hammer mill passes through the screen and leaves the hammer mill with the aid of the pneumatic system. Application: Hammer Mills Uses and Advantages in Grinding Oil Seeds Other Materials Availability Hammer Mills are known as the best grinding machine for all kinds of material, besides oil seeds. A wide assortment of highly developed and advanced Hammer Mills / Disintegrators are available in the market today. They are fabricated to have a strong and sturdy body and are also available in different types, size, and capacities. These come with automatic controls, which makes the machines very easy to use. The number of hammers can also be customized as however the user requires it. Its use increases the output by a large quantity, thus saving more time and energy. Oil Seeds Grinding Grinding of seeds with Hammer Mills increases the quality level of the seeds. Some of the seeds that can be grinded and disintegrated using Hammer Mills are as follows: Cotton seeds Ground nuts Copra Soybeans, etc. Advantages of Using Hammer Mill in oil seed grinding: * Efficient grinding at the shortest time. * Time and Effort saving. * Less electricity power consumption. * Available in different capacities sizes. * Very low maintenance. Conclusion: Hammer Mill is the most common equipment used for the purpose of particle size reduction. It has wide scale of applications in grinding seeds, nuts, and beans and other materials for more industrial purposes. It has the advantage of High efficacy in the shortest time. Thus, considered time saving and less consuming for the human efforts. Beside the low energy consumption, high availability and ease of use and maintenance. It has some drawbacks the most important of which are energy loss, less uniform product and being noisy dust polluting. Its mechanism of action had been explained above in details that it acts to reduce the size of the particles, so, whatever increases the chance of a collision between a hammer and a target, increases the magnitude of the collision, would be an enhancer to particle size reduction.

Glycogen Storage Disease Essay -- Disease, Disorders

Introduction: Glycogen storage disease is the result of a defect in the synthesis or breakdown of glycogen that is found in muscles, the liver and many other cell types. This disease may be genetic or acquired and is usually caused by a defect in certain enzymes that are important in the metabolism of glycogen. To date, there are 11 different classifications for glycogen storage disease but this paper will focus on glycogen storage disease type 1 (GSD I), also known as von Gierke’s disease, after the German doctor who discovered it. GSD I is an inherited autosomal recessive disorder with the incidence being 1 in 100,000. Parents may be heterozygote carriers, making them asymptomatic, however they have a 25% chance of having a child that is affected by GSD I. Prenatal diagnosis can be made by completing a liver biopsy at 18-22 weeks but no fetal treatments are currently available and standard newborn screening tests are not able to detect GSD I. Background and epidemiology: GSD I is a genetic disease resulting from the deficiency of the enzyme glucose-6-phosphate (G-6-P) and glucose-6-phosphate translocase (Andria et al). These particular enzymes are important in enabling the liver to produce glucose from glycogen and/or generate new glucose via gluconeogenesis. The inability of the liver to produce glucose from these metabolic pathways can result in severe hypoglycemia since the liver is responsible for maintaining blood glucose for the body in periods of fasting. The reduction of glycogen breakdown can also cause the kidneys and liver to become enlarged because excess glycogen is typically stored within these two organs. The liver and kidneys can typically function normally during childhood, however because of the increas... ...apter 362.

Dance Therapy Essay -- History Health Therapy Dancing Essays

Dance Therapy Dance therapy is a type of psychotherapy that uses movement to further the social, cognitive, emotional, and physical development of the individual. Dance therapists work with people who have many kinds of emotional problems, intellectual deficits, and life-threatening illnesses. They are employed in psychiatric hospitals, day care centers, mental health centers, prisons, special schools, and private practice. They work with people of all ages in both group and individual therapy. Some also engage in research. Dance therapists try to help people develop communication skills, a positive self-image, and emotional stability. Origins Dance therapy began as a profession in the 1940s with the work of Marian Chace. A modern dancer, she began teaching dance after ending her career with the Denishawn Dance Company in 1930. In her classes, she noticed that some of her students were more interested in the emotions they expressed while dancing (loneliness, shyness, fear, etc.) than the mechanics of the moves. She began encouraging them by emphasizing more freedom of movement rather than technique. In time, doctors in the community started sending her patients. They included antisocial children, people with movement problems, and those with psychiatric illnesses. Eventually, Chace became part of the staff of the Red Cross at St. Elizabeth's Hospital. She was the first dance therapist employed in a formal position by the federal government. Chace worked with the emotionally troubled patients at St. Elizabeth's and tried to get them to reach out to others through dance. Some of them were schizophrenics and others were former servicemen suffering from post traumatic stress disorder. Success for these patients meant being able to participate with their class in moving to rhythmic music. "This rhythmic action in unison with others results in a feeling of well-being, relaxation, and good fellowship," Chace said once. Chace eventually studied at the Washington School of Psychiatry and began making treatment decisions about her patients along with other members of the St. Elizabeth's medical team. Her work attracted many followers and the first dance therapy interns began learning and teaching dance therapy at St. Elizabeth's in the 1950s. Other dancers also began using dance therapy in the 1940s to help people feel more comfortable with thems... ...d to practice. After two years they may receive an additional recognition when they become an Academy of Dance Therapist Registered. They can then teach dance therapy and can supervise interns. Dance therapists can also obtain psychological credentials by taking a test and becoming registered by the National Board for Certified Counselors, Inc.

History of State and Federal Prisons Essay

State and Federal Prison History The basic history for both state and federal prisons are the same, they were both created to incarcerate criminals that were sentenced for a minimum of thirteen months and a maximum of life. However, state prisons are ran by that state government and are usually for those who are considered â€Å"Blue-collar criminals†. Federal prisons are ran by the U.S government and are for those considered â€Å"White-collar criminals†. Both types of prisons have the same levels of security that can range from minimum to maximum. State Prisons State prisons are controlled by state governments and incarcerate â€Å"blue-collar criminals†. A blue-collar crime is any crime committed by someone of lower class. This comes from the term â€Å"blue-collar worker†. Blue-collar workers are primarily paid a lower wage and are mostly middle class people and lower. Blue-collar criminals primarily commit crimes that are of a personal nature (such as robbery). Federal Prison If a criminal is committed of tax fraud then they will most likely end up in a federal prison. Federal Prisons are run by the national government and primarily house those known as â€Å"white-collar criminals†. A while-collar criminal is a person who commits what is known as a white-collar crime such as Income tax evasion. The term white-collar criminal is related to the term â€Å"white-collar worker†, who are mostly those who receive higher wages and are part of the upper-middle class to the higher class range.

Palate-Able Delights: New Modes of Trade Finance

Consideration was to be given to the applicability of non-traditional online and offline moment and trade finance methods (such as those offered by Papal and UPS), open account terms and more stringent, traditional finance methods such as documentary letters of credit. After careful analysis of the circumstances in the case, it is recommended that PAD adopt a flexible payment system adopting a combination of methods. This is dues (due) to the variability In customers It plans to serve, ranging from small, retail orders to orders up to $150,000.Specifically, for orders up (to) or less than $2,000 PAD should employ a flexible, online method such as that offered by Papal, or the services offered by UPS, which include insurance, collections and financing solutions. For larger orders, a documentary collection method of payment provides PAD with the flexibility it needs in order to sell the goods to an alternate customer should a dispute arise before the products perish, while providing th e customer with much less complexity and expense relative to a documentary letter of credit. 1.Introduction and Case Summary The purpose of this report, commissioned by Mr. Jim Dick, Is to analyses the case ‘New Modes of Trade Finance' and answer all discussion questions attached. The case in question describes the situation of Palate-Able Delights (PAD), a niche retailer of high-end food products such as caviar, truffles and French champagnes, who (which) is In the process of assessing several markets for export of their numerous, highly perishable products. PAD Is attempting to determine Its best suited (best- suited) methods of payment, and is intrigued by non-traditional, online payment options such as Papal.However, impacting on the decision process are a number of important considerations. These are: * While largely focused on small, retail sales, PAD Is also considering larger orders of up to $150,000 In value. * PAD Is aware of the trend towards open account terms, and Is Interested In the benefits of conducting transactions on such terms. * Explicitly stated by PAD's SCOFF is that the trade finance solutions offered by UPS be assessed. * Given the perishable nature of PAD's products, speed of settlement must be Incorporated into the evaluation, as do the various cash flow and financing issues affecting both PAD and Its customers.The following sections address the discussion questions. 2 snouts PAD Adsorb some Incremental I costs In Exchange Tort AAA secure Opt to Stay with Traditional Trade Payment and Financing Systems? TTY, Ana Firstly, the nature of PAD's product, being highly perishable, means that both PAD and its customers face a unique risk which calls for a substantial level of importance placed on transit insurance, such as that offered by UPS Capital or Export Development Canada, to mitigate the risk of loss from product spoilage as a result of detrimental shipping issues (such as delays, mishandling, etc. . Given PAD's high margins an d position in a luxury, niche market, the cost of insurance is one that should be absorbed in exchange for the requisite security. In terms of trade payment, the risk of non-payment is significant, given a potential order size of up to $150,000. Important here, however, are the substantially varied sizes of customer PAD plans to serve – I. E. From the relatively small (single consumer, perhaps) to the very large (up to $150,000).This suggests that differing payment systems and, hence, levels of security and costs are warranted. Furthermore, along with the level of broad-based risk (I. E. Country, commercial and foreign exchange – where these are significant, high security methods such as L/CSS or confirmed L/CSS may be necessary, he costs of which should undoubtedly be absorbed), the type of payment system is dependent on the level of demand for PAD's product in a given market, and its objectives for that market.Although PAD is interested in trading on open account ter ms – by far the riskiest for exporters (FIT, 2008), presumably for the potential of greater sales, the risks are somewhat difficult to Justify. Specifically, PAD's a niche business offering high-end, gourmet products – not a commodity-type product attempting to enter a saturated market. As such, while open terms, given their reverence, may be necessary in markets where competition is high and entry to them is deemed strategically significant, PAD likely commands some level of market pull (demand) in most markets.This suggests that PAD's assumption of the substantial risks associated with open account terms is somewhat unnecessary and, given its high margins and assumed ability to absorb some additional costs, it should opt for a greater level of security. This is especially so for small, perhaps one-time customers, with order values of say, under $2,000. Here, non-traditional payment systems such as Papal or credit card facilities are more appropriate than the employ a nd time-consuming traditional payment types. Furthermore, these methods would typically involve payment-in-advance, providing PAD with a high level of security.Alternatively, the services provided by non-bank providers such as UPS Capital, and their Receivables Management Services, which provides credit insurance and collection services amongst others (UPS, 2010), may be appropriate for established, credible accounts who require a more flexible payment method. For large orders, however, the scale of risk increases – especially for those up to $150,000. Here, the security provided by traditional payment types – most appropriately a documents against payment method – and the subsequent absorption of their costs would be recommended.In all, PAD should absorb some incremental costs in exchange for added security. However, traditional trade payment and financing systems may not always provide the best way to garner this security, as ten practically AT sun mentors var ies according to ten size AT P orders, the market it's selling in, and the relationship with the customer. In response to the latter component of the question, a confirmed documentary letter of credit after review of PAD's needs is not the best option. Confirmed Documentary Letters ofCredit are expensive and time consuming and thus not effective when dealing with the purchasing and shipment of perishable foods. The use of Documentary Collections is more tailored to the needs of PAD as the documents arrive with the product. This means that if there is a disagreement or PAD's customer does not provide payment the documents are already with the product and quick resale is possible cutting down the spoilage of goods and ultimately profit. 3. How well suited is Papal, or some variation of online payment solutions to the PAD business model?PAD can offer an all-in-one online service which can be easy, fast and reliable to customers to improve its business. Papal is one such option PAD can use to improve its business online. Papal is customer friendly, with ease of access providing customers with various account types with multiple log-INS and, also, most importantly it's secure. It accepts almost all the major credit cards as well as debit cards which allow customers to make payments for small orders online relatively easily.Papal is the cheapest option available in terms of a Business Merchant account – for customers outside of the states there is no membership fee (residents of U. S pay $1. 90 or 2. 9% of the order depending on the company's purchase).. With regards to PAD ‘s customers, Papal can be time-consuming as it requires the customers to verify funds deposited by Papal into their account. Even though Papal is secure, it involves risks of fraud which, while generally not affecting the customer (as they are covered by Papal and can be reimbursed up to $2,000), may affect PAD via the losses associated with fraud.Merchant/ Business accounts are pro vided by banks which allow the acceptance of credit cards, debit cards or any other form of online payments. The payment is received and updated immediately through automated systems once the order is placed, confirmed and completed. This allows PAD to have direct access and control over the payment processing system and also by using a trade platform to manage open accounts in a manner that provides better payment visibility to suppliers. Also, the use of debit cards can be encouraged as they're easy for customers to use, and possibly less expensive than credit cards.Through this, PAD will gain more direct control over the payment processing system. Although, this additional control means that they will have to deal with credit card fraud directly as well as maintain the functionality of the website as a whole which ay not be possible depending on the understanding and experience employees have dealing with online payment methods. From the customers point of view there are less ste ps needed when making purchases online as well as there is no need to set up a customer account (unless for business specific reasons stated by PAD). 4.What are the Pros and Cons Related to Traditional Bank-provided Trade Finance, and Open Account Solutions?
