My Family – Dad
Im a kind of person that really cares for his family. I have a great education from my father and thats why I admire him for many reasons. Hes a generous person, a great businessman, and a really good father. My dad is always helping people around him. He really cares for his family and he works hard to provide for his extended as well as, immediate family. He supports anyone that has problems with money, police, or any other kind of problem. He is the godfather for everyone in our family. My father is always here when they need them. In the same way, he has also helped his friends. For example: when his friend lost everything, he offered unlimited support to get him back on the right track. He thinks that no one else can do it. He always works with the men word with his friend. He doesnt take a check or title from them for the safety of his money. He is a generous person. My dad had a horrible childhood. When he was three years old, his father passed away. He had to support his family, so he sacrificed himself for them. He left school at the age 12 years old and worked for $ 20 a week. He had a lot of bad memories from his childhood as a consequence; it made him stronger and gave him experiences. He succeeds with the years and he got a lot of business experience. Now, he knows how to handle any kind of business. He could start any business and be sure that he succeeds on it. For example: He bought huge land next to the best tourist area in Casablanca for lot of money. Everyone was thinking that it was a big mistake but it wasnt. After many years, the land value has tripled. I could say that he has the feeling of business in his blood. My dad is a good father for our family. He sends his children to the best school and he doesnt care about the money. He is a powerful father, because he gave the education that he didnt get when he was younger. He made himself clear when something is wrong. If I do same thing wrong, he talked to me one time. He was always there when I need him. For example, I failed my high school two times normally. If he had the Muslim mind, he would let me leave the school, but he didnt. He always gave me a new chance. He gave me the energy to believe in myself and start again. He gave me the opportunity to study in United State of America, support my tuition and my living expenses. There are a few fathers in the world that can spend so much money for their children. In my opinion, I think that my father is the best father I could have ever asked for. I will try my best to be like him by being helpful to my children and people around me. I hope to be able to send my children though college and give them the knowledge needed to successful in society.

Odyssey and O Brother Essay
Thus, we find the modern film depiction of the troubles of a man during the depression is molded by the ancient struggles of Odysseus in Homeris Odyssey. Specifically, three parallels surface in the discussion of the similarities between Homeris classic epic and iO Brother Where Art Thou? The Cyclops encounter for instance, is transcendent between both works. Furthermore, each story contains a comparable perspective of the Lotus Eaters. Finally, the strongest parallel between the iOdysseyi and iO Brother, Where Art Thou? i is the mystical call of the Sirens and the powers of the witch goddess Circe. The Cyclops encounter is transcendent between both works. The Cyclops, in the iOdysseyi and iO Brother, Where Art Thou? i has obvious physical traits that connect the two pieces of work. The Cyclops in each story is a large man, who only has one eye. One website describe the Cyclopes race as, ia rough and uncivilized race of one-eyed giants. i(Spark notes p1) Odysseus describe the giant as, i A prodigious man who slept in his cave alone, and took his flocks to graze afieldââ¬âremote from all companions, knowing none but savage ways, a brute so huge. i(Wilkie p378) The encounter of the Cyclops shows a great similarity in both of these stories. Odysseus, the main character of the iOdysseyi and Ulysses, the main character of iO Brother, Where Art Thou? i are taken from of state of tranquility and savagely attacked. As described by Odysseus, iSo there all day, until the sun went down, we made our feast on meat galore, and wine. i(p 377) This quote describes Odysseus and his men relaxing and enjoying a feast. Quite similar in iO Brother Where Art Thou,i Ulysses was enjoying a picnic when the savage Cyclops attacked him. When Ulysses and Odysseus were about to enjoy a peaceful day they are overtaken by the Cyclops either imprisoned or robbed. Both Ulysses and Odysseus mentality of a warrior allows them to fight back and eventually defeat the Cyclops. In each story an attempt to blind the creature offers a distraction for each character to escape from the Cyclops. Secondly, each story contains a similar perspective of the Lotus Easters. When you eat the intoxicating fruit of the lotus, as described in the Odyssey, the thought of home, purpose of voyage, and memories of the past are no longer important. Odysseus and his men arrive at the land of the Lotus-Eaters and become addicted and drawn to the fruit. They are so leered to the fruit, that it becomes a mindless obsession. iO Brother, Where Art Thou? becomes parallel to the story of the Lotus-Eaters when Ulysses and his men are baptized. Websteris dictionary defines baptism as, ithe Christian sacrament of sin and spiritual rebirth as a Christian. i Both the iOdysseyi and iO Brother Where Art Thou? i describe a rebirth and new thinking. The things of the past are no longer important. Rebirth of the soul and becoming filled with the spirit are identical to the intoxication of the f ruit. Therefore, the producers of iO Brother, Where Art Thou? i are describing baptisms as a new beginning and new thought, then comparing it to the lotus eaters of the iOdyssey. Finally, the strongest parallel between the iOdysseyi and iO Brother, Where Art Thou? i is the mystical call of the Sirens and the powers of the witch-goddess Circe. This parallel is the strongest element of comparison because it is very similar how each story describes the Sirens. Odysseus is told in the iOdyssey,i iSquare in your shipis path are the Sirens, crying beauty to bewitch men coasting by. i (p 421) Both Ulysses and Odysseus use wax to avoid the Sirens. Ulysses hair smelling of wax, (hair wax) and Odysseus instructing his men to put wax in their ears is enough to avoid the Sirens seductive song in each story. Avoiding the Sirens allows both Ulysses and Odysseus to continue on their purpose of journey, to get home. Another striking similarity is the witch goddess of Circe. In the iOdyssey,i Circe turns one of Odysseus men into a pig. Parallel to the Homeric epic, one of Ulysses men was supposedly turned into a frog. These two strong parallels sum up an obvious influence of Homeric work in iO Brother, Where Art Thou? i The movie iO Brother Where Art Thou? i is strikingly similar to Homeris iOdyssey,i in both plot and character description. Specifically, three parallels surface in the discussion of the similarities between the iOdysseyi and iO Brother, Where Art Thou? i The Cyclops encounter for instance, is transcendent between both works. Furthermore, each story contains a similar perspective of the Lotus Eaters. Finally, the strongest parallel between the iOdysseyi and iO Brother, Where Art Thou? i is the mystical call of the Sirens and the powers of the witch-goddess Circe. Thus, we find the modern film depiction of the trouble of a man during the depression is being shaped by the ancient struggles of Odysseus in Homeris iOdyssey.

Answer the question - Essay Example Better services translate upon the overall satisfaction level of the clients. This in turn leads to the positive impact on the staffââ¬â¢s career. Six Sigma is a quality enactment scheme that is mostly applied towards better performance execution. Under this concept the margin of error is highly minimized. The benefits of this mechanism are improved performance, overall satisfaction of the clients and good working relationship between the two ends. Under six sigma principles the error percentage is reduced to less than one percent in total (Chase & Aquilano, 2006, p. 326). Although both the systems are incorporated for quality maintenance and development , yet the two differ on the account of mode of application. Six Sigma may find its limitation of implementation to a more technical and analytical domain of work. T.Q.M in contrast may find its application in a more generic manner. Six Sigma may also differ on the grounds of specialization required towards understanding and implementing it to

Aviation Aircraft Investigation Research Paper Example | Topics and Well Written Essays - 2500 words
Aviation Aircraft Investigation - Research Paper Example Nevertheless, aviation accidents do occur. Between 1999 and 2008 there were 370 aviation accidents, resulting in 4,970 fatalities. Commercial passenger airlines are the least likely of all flights to be involved in an accident (www.1001crash.com). The causes for aviation accidents are varied, but can be categorized into three groups: the physical environment, mechanical failure and human error. Specific issues within each of these three groups are the root cause for all aviation-related accidents. Accidents caused by the physical environment occur from Mother Nature herself. Things such as lightening, wind, ice, rain, etc. are all physical causes. In these cases, it is important for accident investigators to rule out any human error when reacting to physical causes. An airplane sliding off of an icy runway would be one example of an accident caused purely by the physical environment. There is nothing a flight crew could do in this situation to avoid it. Mechanical failure is the next category of accidents. Examples of mechanical failure include complete engine shut down, rudder failure, wheel structure malfunction, etc. Again, there has to be care taken to ensure that human error is not at play in mechanical failure. Investigators have to research carefully to make certain that the failure was completely related to the physical part of the equipment and not the maintenance or lack of. Over the past 20 years, accidents relating to mechanical failures have been steadily declining when compared to other accident causes. Accidents caused by mechanical issues are easier to determine and fix as compared to human errors and the physical environment. When there is a mechanical error, it can be analyzed and improvements can be made in the mechanical structure to avoid the same problem happening again. This isnââ¬â¢t the case for human error (Wiegmann & Shappell, 1997). The remainder of this paper will focus

What characteristics of the opposite gender do heterosexual males and Research Paper
What characteristics of the opposite gender do heterosexual males and females consider most important for sexual and marriage partners - Research Paper Example Many theories have been conceptualized based on the findings of the researches. Cross-cultural evidence proves that men tend to place more value on physical attractiveness while women seek earning potential and possession of resources as valuable traits of potential romantic partners. (Buss et al, 1990). Matlin (2008) explains this gender difference in trait preferences for a partner as based on an evolutionary psychology approach. According to this approach, peopleââ¬â¢s preferences have roots in evolution where men prefer young, attractive, healthy-looking women who are likely to pass on menââ¬â¢s genes to the next generation. On the other hand, women are drawn to men who are economically stable to ensure that their future children are well provided for (Matlin, 2008). This is consistent with the findings of Sakalli-Ugurlu (2003) where women were found to be more concerned about the future security of their future families than men are. Some have very high standards in their choices that nobody comes to par and they end up alone. Men and women hold different views on mate selection. This study aims to explore those differences, specifically on the traits they hold dear in prospective partners. ... These preference for so-called luxuries are held more by more affluent women in western cultures than women in poorer and more traditional cultures (Geary, Virgil and Byrd-Craven, 2004). Men consistently have admitted their primary preference for a partnerââ¬â¢s youth and physical attractiveness as well as a mateââ¬â¢s chastity and sexual fidelity (Buss et al, 2001). This may be explained by the social structural theories. In most cultures, women view marriage as a ticket to material comfort so they search for potential husbands based on their economic potentials and resources. However, as cultures evolve, women have become more empowered in creating their own material abundance through their careers and as they gain economic equality with men, they now focus less on a potential mateââ¬â¢s resources and status and more on aforementioned relationship ââ¬Å"luxuriesâ⬠such as kindness, honesty and a sense of humor. This theory is backed up by Eagly & Wood (1999) who foun d that the structural features of societies may dictate mate preferences. For example, gender differences in preferences for a mateââ¬â¢s earning potential (men) and homemaking skills (women) may be strongly influenced by the economic status held by men and women in various societies. Following the tradition of large-scale studies of Buss (1990) and Eagly and Wood (1999), Lippa (2007) was likewise engaged in a more modern study involving an internet survey sponsored by BBC, wherein over 200,000 participants ranked their preferred traits in potential mates. The 23 trait choices were age, ambition, communication skills, dependability, domestic skills, face attractiveness, fitness, fondness for children, hands, health, honesty, humor, industriousness, intelligence,

Therefore, developing strategies to deal with the high population to support oil production is an issue that involves a vast array of stakeholders.This discussion stresses that immense oil sands growth has brought about wealth and prosperity for the residents of Fort McMurray but at a much greater cost than one would think. Many issues have arisen from the increased development and population growth in the region. Growing concerns of pollution due to the high population and the emissions of greenhouse gases are a hot topic in the Kyoto accord ratification. The Athabasca oil sands are a major contributor to CO2 emission in Canada, emitting about 26 million metric ton s per year, a figure that is expected to grow substantially in the future. Besides, the area has experienced poor sewerage due to the high populations.Ã The oil sands also lie on aboriginal land, creating animosity with the native populations, and creating difficulties in acquiring new land for expansion. According to Melissa Blake, mayor of the Regional Municipality of Wood Buffalo, the high commuter within Fort McMurray creates unruly bumper-to-bumper traffic during peak hours.Ã

Path-Goal and Situational Theories of Leadership Assignment
Path-Goal and Situational Theories of Leadership - Assignment Example Through this, the leader can clearly specify the scopes of the task to be performed and the processes, as well as the responsibilities that the subordinates need to accomplish in order to achieve the set objectives. In this respect, the leadership behaviour tends to be oriented towards achievements, participation, supportive and directive in all aspects. The path-goal theory helps leaders in gaining a proper understanding of their work environments. In this perspective, the leader would develop an understanding of the public health institution, and then clarify the appropriate paths that should be taken by the employees in achieving the set objectives (Sarin & Oââ¬â¢Connor, 2009). Moreover, the theory illuminates the possible obstacles that may prevent the health institution from achieving its set objectives. The path-goal theory is complex since it puts many parameters into consideration and each of these parameters requires proper analysis before selection of a suitable leadership style. Public health institutions comprise sophisticated systems with diversified leadership structures hence analysis and application of these parameters may not be effective. The path-goal theory criticizes the placement of great responsibilities on the leaders and few responsibilities on the subordinates. This makes the subordinates more dependent on the leadership and in the end, inhibits their performance (Laureate Education, 2012). This can have the negative influence on the performance of the workers within the public health sector since they would seek to draw their motivation and skills from the leaders rather than from self. The path-goal theory and the situational theory of leadership both share certain similarities most of which have significant impacts on the nature of leadership in public health sectors. Below are some of the similarities between these two.Ã

How might Pallasmaa's insights about the nature of our interactions Essay
How might Pallasmaa's insights about the nature of our interactions with place help us to conceptualize the complex ecosystems d - Essay Example However, recent studies have shown that the practice of establishing national parks and other protected areas meant to conserve wildlife have not really been beneficial. The reason behind this is that the design of the effort itself takes into consideration the interests of humans more than that of the animals, the supposed beneficiaries. Caroline Fraserââ¬â¢s article Rewilding North America provides a detailed discussion on the problem. It profoundly describes the inadequacies of the national park and protected area systems that exist in the United States in Canada. It also defines the challenges that confront conservationists and the governments of the two countries as they try to seek the most effective ways of protecting the remaining wildlife species in North America. Juhani Pallasmaaââ¬â¢s Architecture of the Senses, on the other hand, may be dealing with how architects tend to disregard the basic human senses as they try to create infrastructure for the use of people. Ho wever, in deriving the basic principles from the architectural theories pointed out in his book, it is clear that Fraserââ¬â¢s key concerns can be addressed by Pallasmaaââ¬â¢s insights. ... When the appreciation of a problem is one-sided or when it does not consider the other angles that may be just as important as that which have been treated, it is only expected that the solutions formulated are those that are bound to fail. In his discussion, Pallasmaa points out that architecture sets limits as to what space man can exclusively use. He explains that ââ¬Å"as a consequence of (the) interdependence of space and time, the dialectics of external and internal space, physical and spiritual, material and mental, unconscious and conscious priorities concerning the senses as well as their relative roles and interactions, have an essential impact on the nature of the arts and architecture.â⬠(Pallasmaa 284) This statement clearly describes that the process of creating a good architectural design is only possible if the architect actually touches base with all the information gathered by using the five senses. If he employs only one of the senses, he is sure to disregard the interdependence of things. It is the issue of interdependence that has also been forgotten when a number of biologists were not able to see the importance of connected ecosystems in order for wildlife to flourish under the most normal natural conditions. Fraser points out that ââ¬Å"many biologists were quick to agree that when it comes to preserving ecosystems, large is better than small, connected is better than isolated, and whole is better than fragmented... some were resistant, arguing against a rush to judgment, suggesting that protected areas in the real worlds might prove vastly more complex, each with unique characteristics that might affect the outcome.â⬠(115) In this statement, Fraser was referring
Stressful Conditions at the Workplace Essay Example | Topics and Well Written Essays - 250 words - 1
Stressful Conditions at the Workplace - Essay Example The other measure to relieve stress in the workplace is accessing training needs and conduct of training to augment effectiveness in job performance including time management and assertiveness training. This can be done through attending short workshops for training purposes and participating in training aimed at improving understanding of stress management practices. Other measures to relieve job-related stress include talking to other employees at the workplace on a stressing situation to gain their support especially human resource managers, colleagues, managers, and trade union representatives (Murray, 5). Talking can also be with people outside of work, for example, family and friends to gain their insight and get their views on the stressful situation. When the issue is excessive workload, the employee should ensure this gets the attention of the manager to allow (Murray, 5)for a better and convenient work allocation fitting the needs of the employees and solve the stress from the job. Maintaining a balance between play and work allows for the use of leisure time to prepare the employee for work and relieve job-related stress. This includes regular exercising, taking holidays, maintenance of a healthy diet, and maintaining support networks. Learning to think positively about a job-related stress, counseling, and seeking medical intervention are the other measures of relieving job-related stress. Ã Ã

The customer can also bring claims against SBL since they were selling inferior products. The customers had started complaining that the quality of bread was deteriorating and that they were selling inferior products. Chapter Two: Discussion Question Two Legal Rules governing the above legal Action On the case where Stoneyground Bakeries Ltd (SBL) is bring an action against Tyre Heaven for selling to them cheap imported tyres that cause injuries to the company's driver a week after they were fitted. The Van driver crushed into a wall after the tyre's tread came off causing him to suffer injuries. This was a clear indication that the tyres were of very low standards hence Tyre Heaven were liable for the injuries caused to the SBL van together with the driver since the van crushed as a result of tread coming of the tyre. When SBL bought the tyres from Tyre Heaven there was an implied condition. A condition is usually a term of greater importance going to the root of the contract. A buyer may waive the condition or may elect to treat the breach of such condition as a breach of warranty, and consequently claim damages instead of repudiating the contract all together. The buyer is bound to treat the breach of condition as a breach of warranty where the contract is not severable and he has accepted the goods, or part thereof or where the contract is for the sale of specific goods, and the property in them has already passed to the buyer. The parties are, however free to contract themselves out of this rule by including a stipulation to that effect in which case the terms of the contract will not be affected by the provisions. For the case of sale of tyres by Tire Heaven, there was an implied condition as to merchantability. A

E-Services in Cambodia Essay Example for Free
E-Services in Cambodia Essay The day length varies from 11 hours 29 minutes to 12 hours 48 minutes without twilight. Mean maximum and minimum temperature range among 30 to 36à °C and 21 to 25à °C respectively. Annual rainfall is 1,343 mm mostly during May to November. The national economy of Cambodia similar to many other developing countries are largely based on agriculture and income-earning opportunities. 90% of Cambodian population makes its living from agriculture. Agricultural development becomes important not only for food and livelihood security of the rural families, but also as a support for industrial progress. Most of Cambodian farmers are poor and live under extreme agroecological, socioeconomic constraints and fear of unrest of war. The poor farmers with small and scattered holdings are surviving on rain fed, mono cropped and rice based farming. Cambodia is rice exported country of mid 1960s has now annual shortage of about 50 000-70 000 tons. Out of exported rice, Cambodia has also exported many agricultural products such as timbers, fish, maize, rubbers, soybean, ground nuts, sesame, jute, cotton and tobacco. These products have been used very low by Cambodian people, because of lacking technology and facilities to improve qualities for food consumption. Agricultural sector in Cambodia contributes about 45 percent to the GDP, and more than 80 percent of the population earns their livings from the agriculture. Apparently, a process of agricultural development is considered to be an effective approach to promote the economic growth with a broadest possible base. Nonetheless, the development of this sector is mainly constrained due to the exceptionally low productivity if compared with the neighboring countries. Research on agricultural development in developing countries has clearly shown that the fundamental problem of agricultural growth is an agricultural education as it plays a vital role in providing qualified manpower for agricultural requirements and conducting agricultural research, thus providing farmers with new techniques of production and new input. Indeed, innovation of technology and management capacities for more intensive and modernized griculture becomes paramount to maximize agricultural output to ensure food security and to alleviate rural poverty in the country. Needless to say, this can be accomplished through the upgrading of human resources employed in the sector at a ll levels from the basic education to higher education. Cambodia has two rice crops each year, a monsoon-season crop (long-cycle) and a dry-season crop. The major monsoon crop is planted in late May through July, when the first rains of the monsoon season begin to inundate and soften the land. Rice shoots are transplanted from late June through September. The main harvest is usually gathered six months later, in December. The dry-season crop is smaller, and it takes less time to grow (three months from planting to harvest). It is planted in November in areas that have trapped or retained part of the monsoon rains, and it is harvested in January or February. The dry-season crop seldom exceeds 15 percent of the total annual production. The per-hectare rice yield in Cambodia is among the lowest in Asia. The average yield for the wet crop is about 0. 95 ton of unmilled rice per hectare. The dry-season crop yield is traditionally higher, 1. 8 tons of unmilled rice per hectare. New rice varieties (IR36 and IR42) have much higher yields, between five and six tons of unmilled rice per hectare under good conditions. Unlike local strains, however, these varieties require a fair amount of urea and phosphate fertilizer (25,000 tons for 5,000 tons of seed), which the government could not afford to import in the late 1980s. The main secondary crops in the late 1980s were maize, cassava, sweet potatoes, groundnuts, soybeans, sesame seeds, dry beans, and rubber. According to Phnom Penh, the country produced 92,000 tons of corn (maize), as well as 100,000 tons of cassava, about 34,000 tons of sweet potatoes, and 37,000 tons of dry beans in 1986. In 1987 local officials urged residents of the different agricultural regions of the country to step up the cultivation of subsidiary food crops, particularly of starchy crops, to make up for the rice deficit caused by a severe drought. Animal husbandry has been an essential part of Cambodian economic life, but a part that farmers have carried on mostly as a sideline. Traditionally, draft animals water buffalo and oxen have playe a crucial role in the preparation of rice fields for cultivation. In 1979 the decreasing number of draft animals hampered agricultural expansion. In 1967 there were 1. 2 million head of draft animals; in 1979 there were only 768,000. Cambodias preferred source of protein is freshwater fish, caught mainly from the Tonle Sap and from the Tonle Sab, the Mekong, and the Basak rivers. Cambodians eat it fresh, salted, smoked, or made into fish sauce and paste. A fishing program, developed with Western assistance, was very successful in that it more than quadrupled the output of inland freshwater fish in three years, from 15,000 tons in 1979 to 68,700 tons in 1982, a peak year. After leveling off, output declined somewhat, dipping to 62,000 tons in 1986. The 1986 total was less than half the prewar figure of some 125,000 tons a year. Saltwater fishing was less developed, and the output was insignificant, less than 10 percent of the total catch. According to the First Plan, fisheries were projected to increase their annual output to 130,000 metric tons by 1990. II. Potentiality of paddy production in Cambodia Paddy Production Wet rice is a unique crop in many ways: It is a traditional, reliable and appreciated stable food â⬠¢ It provides a livelihood for many people (for example some 75 percent of the people living in the Lower Mekong Basin) â⬠¢ It can grow in places that are unsuited for other crops, including waterlogged or inundat ed areas â⬠¢ It can be stored for months or years, if need be â⬠¢ It is rather robust towards pests, and very robust towards weeds â⬠¢ It can be raised within the period of a monsoon rainfall Water for cultivation Having developed in a context of abundant water availability, traditional wet rice cultivation is not water-efficient at all. Production of 1 kg milled rice can require the availability (if not consumption) of 3-6 m3 of water, including various losses and return flows. The monsoon rainfall in Cambodia, where most paddy fields are rain fed, with others supplied by seasonal flood water, and/or from irrigation. The seasonal variation is rather predictable, but the cultivation has adapted so closely that small deviations from the normal pattern can have a significant effects. This is particularly the case for the small dry season, a dry spell of perhaps around a couple of weeks not long after the onset of the wet season. A protracted and severe small dry season after transplanting can seriously affect the annual rain fed crop. 2. The traditional cultivation systems a. Rain fed rice cultivation -The cropping system Rain fed rice cultivation is linked to the rainfall. Over the centuries, the timing and duration of the cultivation cycle have adjusted accordingly, depending on local soil conditions. Due to uncertain rainfall, risk aversion is a strong consideration in choice of technology and in technological innovation for rain fed lowland rice. Traditionally, seeds are produced simply by retaining a portion of the harvest. Better seeds can make a visible difference, both regarding yield and robustness, but must be bought from the good seed keepers in the local area at intervals of a few years. Also, fertilizers can highly improve both the yield and the resilience of the crops. However, the opportunity for its application depends on the rainfall. The size of the land holding is important to the viability of cultivation of rice as well as many other crops. Land holdings in Cambodia tend to be minimal. One among other reasons is the increasing population combined with generation shifts. The farming system Traditional farming systems provide a balance between the availability of land, water and labor, in response to household needs and market demands. Paddy cultivation is highly labor-intensive during transplanting and harvest, but less so in other periods, and not at all outside the cultivation season. Therefore, it can conveniently be combined with other occupations. A traditional Cambodian farming system would comprise paddy cultivation, livestock and palm sugar production. Todays farming systems can be more diverse. Examples of their elements are, A typical Cambodian cultivated landscape is recognised by its sugar palms. A sugar palm can produce 25-50 kg sugar per season (which is 5-7 months), providing a supplementary occupation and cash income. Trees that are unproductive for sugar can supply leaves for thatch-making, mats or rice bins, and can eventually be used for construction and fuelwood. Sugar production is labor-intensive and can compete with Labor for other purposes. Also, it requires fuelwood. It is regarded as a hard way to earn an income and is now in decline. The agricultural value generation Cultivation generates a substantial value upstream and downstream of the farm level, in connection with production and supply of inputs, and processing and distribution of outputs. Rice milling is capital-intensive and is provided by speciali zed operators outside the village. The millers often serve as wholesale buyers. They may provide loans to the farmers with the next crop as collateral, or the rice can simply be sold some time before it is harvested. Few Asian paddy farmers have direct access to (or exposure to) an open market. Some countries see a rather monopolized distribution at the wholesale level. Many governments try to square the circle between appropriate revenue at the farm level and affordable food to the urban poor, applying gentle or more strict regulation of trade and/or prices. Conditions can be quite different for crops other than rice an aspect that can favor a certain crop diversification. b. Irrigated rice cultivation The cropping system Small parts of rain fed rice areas have irrigation or supplementary irrigation. A higher reliability of access to water reduces a major risk and provides opportunities for innovation, provided that technology, skills and inputs are available. This requires coordination of the development of irrigation services and agricultural education and services. Where raw water is available for dry season irrigation, it becomes possible to raise two (or perhaps even three) crops per year an obvious opportunity, so much more because the dry season yield is much higher that the wet season yield (due to the higher sunlight radiation from clear skies). A shift from one to two crops require a shift from long-duration to medium- or short duration varieties. For example, a medium-duration variety can be grown in the wet season and a short-duration variety in the dry season. The farming system Sharing an irrigation system requires an even stronger collaboration than rain fed cultivation, and ability to collaborate is one of the several success criteria for new systems. Farmers Water User Communities (FWUCs) are promoted by Ministry of Water Resources and Meteorology (MOWRAM) in support of de-central support to operation and maintenance. Some of these work well, while many others are in need of consolidation, faced with complex new challenges and a need of close collaboration. If water is available but sparse in the dry season, a part of the land can be cultivated with crops other than rice. The soil quality, taken as a given without irrigation, get a new significance in connection with the new potential cropping opportunities. Soil conditioning becomes a new requirement in connection with crop diversification in areas that are not immediately suited for crops other than rice. Land becomes an even more precious production factor when irrigation is available, as reflected by a higher price. This makes sense, because of the higher revenue that can be generated, but it also imposes a pressure on the land ownership in case of social shocks, such as failed crops or illness in the family, where households risk to lose their land and turn to sharecropping. This is a visible tendency in newly irrigated areas. The need for supplementary occupations remains, one reason being the moderate income generated from rice cultivation. Households that combine paddy cultivation and livestock will typically earn more from the latter. Cattle and buffaloes can feed on marginal lands unsuited for cultivation, and on by-products such as straw, husk and bran. They provide manure, and draft animals can generate a cash income from transport and ploughings. Further, cattle and buffaloes provide capital for emergencies (such as medical treatment costs in case of illness in the family). The agricultural value generation A second annual crop will highly benefit from more external inputs seeds and fertilizer- and will in turn supply much more rice to the market, considering that a substantial part of the first crop from a small land holding is consumed by the household. This amplifies the value (and livelihoods) generated before and after the cultivation hopefully to the benefit of the farmers as well as society as a whole. 3. Traditional gender roles There are some traditions in connection with the task allocation between the household members. These traditions are not strictly observed, however, and all hands are at work during busy periods. 4. Trends Traditional paddy cultivation is developing in response to challenges, such as for example: â⬠¢ A stronger market demand for crops other than rice including vegetables and biofuel crops, as well as a stronger demand for meat; â⬠¢ a stronger competition for raw water in the dry season, related to development of irrigation infrastructure and intensified cultivation; and/or â⬠¢ a stronger exposure to competition, related to improved transport infrastructure, porous borders, and regional and international promotion of lower trade barriers. Also, inevitably, modern lifestyles will reach even remote, traditional farming households. A cash income is needed for clothes and kerosene (or electricity where available), and every household strives to achieve a TV, a hand phone, and a motorbike. In many cases, this requires paid off-farm employment by one or several household members typically young adults, who migrate to the towns in search of work. III. Quality a. Milling and reprocessing plants Milling and reprocessing plants are being upgraded with high capacity and modern technology to ensure quality of rice. The global milled rice trade in 2010 has been estimated at around 31. 3 million tons, compared to 29. 7 million tons in 2009. However, the demand for the import of medium and low-quality milled rice has been on the increase in Asia, due to the weather problems in the Philippines, crops failure and reduced subsidy on fertilizers in Indonesia, as well as the requirement by some countries in the region to fill in reserve stock. It is estimated that milled rice trade in Asia may reach 14. 5 million tons in 2010, and at the same time, the milled rice price may increase and fluctuate. Overall, the regional and global milled rice trade has high growth potential for the medium and long term, but there are some down-side risks, due to factors such as changes in prices resulted from changing economic and political landscape in every country across the globe. The potential for increasing milled rice trade could be attributed to factors such as population and economic growth and globalization that imply changes in lifestyle and taste in rice consumption. However, the global milled rice markets are protected and highly subsidized because of its political sensitivity and paddy rice growing tradition being important in the context of national religion and food security. Nevertheless, such developments provide an opportunity for Cambodiaââ¬â¢s milled rice export into the global markets. Milling Rice Cambodian farmers take immense pride in having commenced construction of International standard rice mill in Cambodia. The state-of-the-art high capacity paddy-to-white rice mill in the Udon region is anticipated to be commissioned in Q3 2012 and represents the first of multi-phase investment strategy and deep-rooted commitment to the country. Significantly larger milling lines are planned for commissioning throughout 2013-2015. The complete milling operations are being designed from the ground up by world-renowned rice experts with unparalleled expertise in advanced rice milling process and technology currently used by the worldââ¬â¢s most successful rice millers. The advanced mill design will provide immense flexibility in processing capacity enabling us to handle large scale paddy in short harvesting periods without affecting quality. All mills will be fully equipped with state of the art rice milling, grading, sortexing equipment from Japan and modern packing facilities to ensure consistent production of products to the highest standards whilst meeting the highest stringent quality and safety requirements of the national and international food and retail industries. Utilising multipass technology consisting of whitening and polishing, we can ensure efficient removal of bran and an extremely clean white appearance to the individual rice grains. Our optical sorters look at each individual grain of rice detecting shape, length and colour which guarantees uniformity and an average grain length. Reprocessing plants Until recently, Cambodian farmer didnt have access to high-quality rice seed. For years, the farmer did what most Cambodians do when itââ¬â¢s time to plant their fields: use leftover seed from a past harvest. But the quality of the resulting crops tended to be poor, producing rice that was often pale brown, small, and lacking in aroma. As a result, buyers and rice millers offered low prices, and his sales and income suffered. Almost of Cambodian farmer finally has access to high-quality seed. On the advice of program agronomists, since 2000 they planted a small test plot of the Phka Rumdoul variety to be used exclusively for re-planting. Phka Rumdoul is one of 10 rice varieties recommended by the Cambodian government for their high productivity, quality, and market value. Cambodian farmer harvested the test plot four months later to great success. Though the initial plot was small at 1,500 square meters, the harvest provided enough seed to plant his entire farm of five hectares next season. Program agronomists estimate that the improved seed ââ¬â combined with Ministry of Agriculture Forestry and Fisheries of Cambodia planting methods ââ¬â will save them an estimated 70 percent on seed inputs and increase their sales by roughly 100 percent, both through increased production and higher prices when he sells. Lack of high-quality seed is a major hindrance to Cambodiaââ¬â¢s rice industry. If the country hopes to reach the governmentââ¬â¢s target of exporting 1 million tons by 2015, Cambodian farmers must improve the quality of their product to make it more desirable to overseas markets. Increasing access to high-quality seed ââ¬â in addition to good agricultural practices and improved marketing techniques, both of which Ministry of Agriculture Forestry and Fisheries of Cambodia is addressing ââ¬â is crucial to this happening. About 5,352 rice Cambodian farmer receiving technical assistance from Ministry of Agriculture Forestry and Fisheries of Cambodia, a number that will grow to 30,000 over the life of the program. They have no doubt that Phka Rumdoul can find a market outside of Cambodia. ââ¬Å"These seeds are high quality. You can tell just by looking,â⬠they said one recent afternoon, sifting the grain through his fingers. ââ¬Å"With good seeds and Ministry of Agriculture Forestry and Fisheries of Cambodia techniques, Iââ¬â¢m confident that I can produce high-quality, tasty rice. â⬠b. Good and fertile soil condition and fertilizer usage Farmer use limited chemical fertilizer and natural fertilizers to its actuality: produce high yield and good quality paddy and good tasted rice. Fertile soil condition At the time of writing this report there were no data available on the degree of erosion in Cambodia. But because of the high vulnerability of soils to erosion in Cambodia and the accumulated impact on agriculture and the environment, attention urgently needs be given to the problem. That need is underscored by the following facts: Some 63 per cent of Cambodiaââ¬â¢s forests are located in mountainous watershed areas (Ministry of Environment, 1994), much of which has been extensively logged, deforested or degraded. Loss and reduction of the vegetation cover leads to exposure of the soil to sunlight and heavy rainfall, which speeds up the decomposition rate and therefore decreases organic matter in the soil. The process also brings about changes in the physical and chemical soil structure. Consequently, the soil undergoes crusting, and the water filtration, and water and nutrient retention capacity are reduced. The end result is intensive run-off and erosion; Some provinces in Cambodia, sheet erosion can be seen as silt which has collected behind cut logs and stumps in the fields, while rill erosion occurs in some fields only three months after clearing and burning the forest for farming. When that occurs, the actual amount of top soil being lost, measured from the top of the remaining grass and tree stumps to the soil surface, is an estimated 1 to 1. 5 cm. The fact that rill erosion has already begun in some places suggests that the yearly top soil loss is very serious. Farmers have reported that yield decreases about 20-25 per cent in the second year of cultivation, and about 40-50 per cent in the third year on wards. Soil loss through erosion can be observed at coffee and hevea farms where the natural vegetation cover has been completed cleared, leaving the soil surface uncovered between the rows of young seedlings. Erosion occurs not only in the upland areas but also in the lowland areas. In practice, water run-off occurs on all land, and the top soil is lost when no protective and conservation measures are in place. In Cambodia, however, few people understand that erosion is a serious problem in the rain fed lowland areas. In addition, population pressure in the rain fed lowlands is triggering a chain of events which will lead to intensive run-off, erosion and a reduction in the groundwater recharge. Those events include: Excessive collection of fuelwood from woodland and forest areas; Overstocking and overgrazing (although the number of animals is increasing, the fodder supply is decreasing); Increased run-off of water from rice fields. Because dikes in some areas, for example, in Svay Rieng, are not high enough to contain rainwater, the run-off contains a great of nutrient. Fertilizer usage The average rice yields in Cambodia over the past five years have been relatively constant, varying between 1. 2 and 1. tons/ha in the monsoon season and 2. 5 to 2. 7 tons/ha in the dry season. During 1995/ 96 a considerable increase in rice yield was recorded: 1. 64 tons/ha in the monsoon season and 3. 0 tons/ha in the dry season (Ministry of Agriculture, Forestry and Fisheries, 1995). That rise in yield has b een linked to good weather conditions, increased use of fertilizer and the expanding cultivation of high-yielding varieties in the dry season1 . For other important secondary crops the yield has remained relatively constant. The average yield of cassava is 6. 61 tons/ha, sweet potatoes 4. 16 tons/ha, mung beans 0. 78 tons/ha, sugar cane 27. 29 tons/ha and soybean 1. 7 tons/ha (Ministry of Agriculture, Forestry and Fisheries, 1995). Soil fertility depends on the agro-ecosystem. There are four important rice agro-ecosystems in Cambodia: rainfed lowland rice; rainfed upland farming; deep-water or floating rice; and dry-season (mostly flood recession) rice. While declining soil fertility is increasingly affecting the rainfed lowland agro-ecosystem, the soil fertility in the other systems can be restored through yearly siltation or through the clearing of forest areas. Unfortunately, the rainfed lowland agro-ecosystem is the most important in Cambodia because that area covers about 85 pe r cent of the cultivated area of the country. Rice in that ecosystem is commonly grown on Ultisols and Alfisols (Reyes and others, 1995). Those soils, especially Ultisols which comprise the most common rainfed lowland soil, are sandy, acidic, extremely infertile and low in organic carbon and cation exchange capacity. The rainfed lowland areas are badly degraded, especially where land settlement has continuously occurred over hundreds of years (for example, Oudong in Kampong Speu province, and Bati in Takeo province). In those areas, the soils are very sandy and the top soil has been seriously depleted or eroded. IV. Price, Tax-free and Market of Cambodian rice a. Cambodian rice price in the market Cambodian riceââ¬â¢s price is competitive, especially fragrant rice. Cambodian milled rice is becoming more popular throughout Asia, particularly in Malaysia, which is the number one importer of milled rice from the Kingdom. The price of Cambodian paddy rice is 30% to 40% cheaper than its neighbors Thailand and Vietnam. This low profit margin is a competitive advantage but unofficial fees, high transportation costs and high processing costs make this less significant. Exporting paddy rice is a lost. If processed domestically, some byproducts such as broken rice, husk and bran can be used as important inputs for aquaculture and animal breeding that enable farmers to earn extra income. With more investment in modern rice mill facilities, Cambodia can increase its production of quality milled rice for the growing international market and boost the reputation and international recognition of the Cambodian milled rice standards. In this connection, the Royal Government must address the following issues to increase domestic value-added: High electricity price Electricity represents 25% of the total processing costs. This fades Cambodiaââ¬â¢s competitive advantage and the situation can be worse taking into account high and volatile oil price. High energy price is an obstacle to the expansion of the irrigation systems. In the low land Mekong plain, petroleum products are used to pump water into irrigation canals. Therefore, high energy prices limit the ability of farmers to plant two paddy crops a year and to increase yields. For instance, urban dwellers pay 18 20 cents per kWh, while those living in the rural areas are forced to pay up to 30 90 cents, compared to 10 cents in Vietnam. Unreliable supply and high electricity price force rice mills to use their own diesel generators which cost them 12. 60 dollars or 2. 2% per ton of rice, compared to 23. 38 dollars or 4. 1% per ton if electricity is used instead. High transportation cost Poor transport infrastructures such as roads, railways, warehouses, and handling equipment increase rice price. To transport one ton of rice on 100-km road, Cambodian farmers must spend 15 dollars, while this costs only 4 dollars and 7. dollars in Thailand and Vietnam respectively. Moreover, the number of handling equipment and port-nearby warehouses are not adequate, a major challenge for rice export especially during rainy season. Lack of access to and high cost of credit Lack of access to and high cost of credit decrease domestic value-added and hinder milled rice expor t. Limited access to credit, both for working capital and investment outlays, represents an obstacle for rice millers to stockpile paddy rice and modernize their processing machineries. However, given the sound and vibrant banking system and a large amount of available credit lines, the capital and the costs of financing should not be a problem. The problem is that bank intermediaries do not clearly understand the risks and the expected returns from agriculture investments, as the majority of bankers believe that agriculture is a high risk and low return sector. Moreover, lack of borrowersââ¬â¢ financial information and records make it more difficult for the banks to assess the repayment capacity and the status of the borrowers. b. Tax-Free for Cambodian rice export Nowadays, Cambodian rice can export to some countries in the world is tax? free, e. g. , the EU Countries, Russia and China. However, the Ministry of Economy and Finance has issued a prakas that will exempt rice producers from a 1 per cent tax in a bid to stimulate rice production and exports. The prakas, or edict ââ¬â dated October 11 and signed by Minister of Economy and Finance ââ¬â rescinds the tax on rice production and milled rice sales for three years. The move comes as the Cambodian government attempts to close in on its goal of exporting 1 million tonnes of milled rice by 2015. President of Loran Import-Export Company, said was not aware of the prakas, but added that the tax relief would help the countrys rice exports as soon as it was implemented. Rice exporters have long insisted that Cambodia remove domestic rice production taxes, Minister said. Thailand and Vietnam do not have such taxes, and the removal of the tax would put Cambodia on a more equal playing field, he said. It would encourage exporters, including me, to be more motivated to export. General director of Rural Development Bank, said he was not sure of the significance of the prakas yet but he supported the ministrys attempt to push milled rice production. The ministry had tried to facilitate milled rice production very much. They have pushed hard for tax exemption of export,. As a relatively new player in the milled rice market, Cambodia faces a steep learning curve. However, with a surplus of 3. 5 million tons of paddy rice (equivalent to 2 million tons of milled rice), Cambodia has the potential to soon be among the top five milled rice exporters in the world. More importantly, growth in the agricultural sector will translate into more economic opportunities for Cambodiaââ¬â¢s vast rural population. While not a silver bullet, the success of the rice sector is an exciting and potentially crucial driver in Cambodiaââ¬â¢s prosperous and equitable development. c. Market Milled rice market is heavily protected and import procedures vary from one country to another. As Cambodia is a new player in milled rice market, it must face a steep learning curve and improve its export capacity to penetrate the international market. According to data from the Ministry of Agriculture, Forestry and Fisheries, Malaysia imported over 7,000 tonnes of a total 25,700 tonnes exported. Poland is the second-largest importer, importing 5,880 tonnes in the first month of the year, and France the third largest, importing over 4,300 tonnes. The of Ministry of Agriculture, Forestry and Fisheries and director of the single-window secretariat for facilitating milled rice exports, said though Malaysia ranked highest for milled rice exports, Cambodia could further capitalist on Malaysian demand for fragrant milled rice. Cambodia needs to diversify its exports to better take advantage of the Malaysian market, Vanhorn added. But Cambodia also still faces challenges in managing the use of different seeds grown in different areas, adding that officials could not always control the quantity of these unspecified seeds ââ¬Å"According to these figures, we hope we reach our target, but anything can happen in the future,â⬠Minister said, adding that ââ¬Å"rice exports can be affected by many other factorsâ⬠. The Asian market is huge for rice exporters, with Malaysia importing from Thailand and Vietnam as well. Malaysia imports a lot of rice to supply its market demand from Thailand and Vietnam, and now they also turn to Cambodia because of competitive prices. Cambodia announced two major bilateral trade agreements last month, with the Philippines and Thailand, that are expected to further expand the countryââ¬â¢s rice export sector. Over the last few years, Cambodia has emerged as a major rice exporter in the region, due in large part to the Royal Government of Cambodiaââ¬â¢s recent expansion of its agricultural sector. Agriculture, led by rice farming, contributes to roughly a third of the countryââ¬â¢s GDP and has immense potential for strengthening Cambodiaââ¬â¢s economic growth, accelerating poverty reduction, and improving the living standard of its citizens. As part of this agenda, in 2010, the RGC adopted a new Policy Paper on Paddy Production and Rice Export, better known as the Rice Policy, to promote diversification of Cambodiaââ¬â¢s economic sectors by catalyzing growth in paddy rice production and milled rice export to match the growth seen in the garment and service sectors. In his keynote address at the policyââ¬â¢s launch, Prime Minister said: ââ¬Å"The policy aims to ensure that we grab the rare opportunity to develop Cambodia in the post global financial and economic cataclysm. â⬠If Cambodiaââ¬â¢s rice export sector were to reach its full potential, it could produce 3 million tons of milled rice, with the total export value amounting to $2. 1 billion (approximately 20% of the GDP) and an estimated additional $600 million (approximately 5% of the GDP) to the national economy. It would also boost employment and income for agricultural farmers who make up more than 70 percent of the population living in rural area s. To better understand the bottlenecks in the rice sector, The Asia Foundation, in partnership with the AusAID-funded program, ââ¬Å"Cambodia Agricultural Value Chainâ⬠(CAVAC), hosted a series of consultative forums last year in three provinces ââ¬â Kampong Thom, Kampot, and Takeo ââ¬â with stakeholders from the private sector (farmers, seed producers, agro-business owners, exporters) and the public sector (Ministries of Agriculture, Commerce, and Water Resources Management, provincial governors, provincial departments of line ministries, and local authorities). Approximately 370 participants attended the workshops and discussed how to create business-friendly environments (i. e. competitiveness and productivity, access to finance, access to markets), and the technical aspects of rice production (use of fertilizers and insecticides, seed categories, and availability of water sources). The insights were frank and eye-opening. Although the challenges are significant, the o pportunities for the sector are greater. Secretary of State for the Ministry of Economy and Finance, optimistically predicted that the RGC can achieve its target for milled rice: ââ¬Å"With regards to RGCââ¬â¢s rice export target in 2015, we may achieve up to 80 percent of the 1 million tons planned. This should include the milled rice to Vietnamese, Thai, and non-EU markets. â⬠Implementing a strategic framework like the Rice Policy is just the beginning. To increase the paddy rice production to meet market demand and promote the export of milled rice, the government must initiate and support a host of reforms in partnership with the private sector. For instance, to solve the issue of credit shortages for buying and processing paddy rice, the government can provide incentives to commercial banks to increase the loan portfolio for agriculture. At the end of the day, the RGC must keep the farmers themselves in mind. Introducing new technologies or improving agricultural practices can only go so far if they are not accepted and adopted by farmers. Donors and NGOs can play a pivotal role in providing support and facilitating the successful implementation of new policies and projects aimed at improving the agricultural value chain. V. Conclusion Though the current global milled rice market is highly protected, Cambodia is blessed with opportunity to export milled rice in the future thank to the increase in domestic paddy rice production and the potential in the world milled rice trade. So far, the performance of agriculture is outstanding especially in terms of productivity improvement and diversification, due to steadfast efforts of the Royal Government and all stakeholders including the participation of farmers. Rice will mainly mean the stunning landscapes of rice fields, yellow at harvest time, bright and liquid during the rainy season, with shades of green meanwhile. But to a Cambodian consumer and to a Cambodian farmer, as well as to their Government (and to the French economist), rice is the staple crop, a possible ââ¬Å"white goldâ⬠as the Prime Minister once put it, and a major part of a poverty reduction strategy. Through, the Prime Minister launched a ââ¬Å"policy paper on the promotion of paddy production and rice exportsâ⬠. This is a good and promising example of a cluster approach to Cambodias growth strategy. Cambodia is an important but still small rice exporter. Cambodia has been an exporter of rice since 2004, but a large part of the exports was unprocessed (paddy) or even smuggled through the border. Yet Cambodia has abundant land and sits in a region that is both fertile for and in high demand of rice. So far the potential comparative advantage for rice was diluted by various costs, official (e. g. electricity) or unofficial (e. g. llegal check points). Poor coordination of public and private actors was also undermining the potential. For instance weak land titling systems and weak sanitary controls were a constraint that led to limited access to finance, itself contributing to limited value addition. However the significant increase in price in 2008 and again a rebound in the past few weeks has drastically changed the economics of the sector. The policy includes a range of actions, from helping farmers to organize in associations and use better seeds, to improving irrigation systems, developing certification systems, strengthening logistics, and facilitating access to finance. Although I did not get a chance to consult Paul the Octopus as my colleague in Thailand did, the policy makes a strong case for the rapid development of rice exports in Cambodia. Potentiality of Cambodian rice, Cambodia has great potentialities and prospects in paddy and rice production promotion for the supply. Cambodia will be able to produce large quantity of paddy in response to the increasing demand of the world markets. In the future, Cambodia necessarily need to export milled rice in large quantity rather than selling as paddy rice. In fact, high growth in agricultural sector will benefit most Cambodian people who are farmers with their living standard improved. Thus, the Royal Government is committed to promoting paddy rice production and removing all constraints to milled rice export from Cambodia. Indeed, the success of this policy will depend on actual implementation; and the task is complex and hard to achieve, yet it really requires cooperation, coordination and strong commitment especially by way of improving the leadership and management of all concerned ministries/agencies and stakeholders. The new policy recognizes this new environment and promotes: coordination of various actors along the value chain, from the rice fields to the export market; shift from production increase to commercial agriculture; and Organic rice should be promoted country wide Link all producer group into cluster and union Farmers should involved in this industry and form themselves into network Local and national authority support the industry NGO should provide more capacity building training related to value added Government should re-check the policy of land investment ( esp. land concession) Government should rehabilitate the existing irrigation system and build the new ones where the re is lack of irrigation system Government should facilitate to find the loan or provide loan to farmers with low interest rate to ensure that farmers will have enough financial resource to invest in this industry. Both government and NGO must try to look for and expand the market for organic rice products. Recognition of the leading role of the private sector and the critical facilitating role of the State. The Royal Government is strongly convinced that all ministries/agencies of the Royal Government and other stakeholders, including the private sector and development partners, and particularly Cambodian farmers across the country, will join hands in pursuing this mission to bring about development, progress, and prosperity to the Kingdom of Cambodia.

Abigail Williams Character Essay
Abigail Williams Character Essay Being hung because of someone elses lies, selfishness, and lustful temptations, seems fair right? This is exactly what happened because of Abigail Williams. 19 people were hanged during the Salem Witch Trials, which was consequent of Abigail Williams lies, and selfishness. Abigail was the young women that John Proctor had an affair on his wife with. After the affair, she became obsessed with John, despite his constant reassurance that what he did was wrong, and that he was through with her. She became obsessed to that point that she drank blood, and did a dance with the devil in order to see Mrs. Proctor killed. After this didnt work, she began telling lies about seeing others (including Mrs. Proctor) with the devil, so that she would be hanged and she could possibly live a life with John. Analysis and study of Abigail Williams in The Crucible shows that she is a villain with manipulative skills, and is a compulsive liar, who is motivated by sexual temptation and John Proctor. Abigail Williams is a prime example of a villain because of her actions in The Crucible. One of the things that she does to portray her as villain is she lies about Tituba forcing her to drink blood, when really she did it under her own will. While Abigail was being pressured into saying who was involved with the Witchcraft she said, She (Tituba) makes me drink blood! (47). This resulted in Tituba being brutally beat and eventually sent back to her old country. Abigail also victimizes herself, in order to make it seem like she is innocent. For example she says, She sends her spirit on me in church; she makes me laugh at prayer! (48) during a court session. Abigail is also really good at drawing attention away from herself because another time during a court hearing, when she was about to get proven a liar, she suddenly acted as if there was a demon in the room. She screamed with terror, Shes going to come down! Shes walking the beam! (120). All of these instances do a great job of sh owing that she knows how to play the role of a villain, by making herself seem innocent. Abigail has some major strengths that help her in being a villain, and those strengths are compulsive lying, and extremely good manipulative skills. Everyone knows that Mrs. Proctor is a goody woman in Salem; however, because she has something that Abigail wants she chooses to lie about the type of person she is in order to manipulate the way people view her by saying, Its a bitter woman, a lying, cold, sniveling woman, and I will not work for such a woman! (12). She also was asked if she was the one conjuring spirits and she answered by putting the blame and Tituba and Ruth. Abigail replied, Not I, sir Tituba and Ruth. (16). Betty (who has fallen sick and unconscious due to the conjuring of spirits) also even admits what she saw Abigail do, to kill Proctors wife. Betty exclaimed, You did, you did! You drank a charm to kill John Proctors wife! You drank a charm to kill Goody Proctor! (20). Abigail consistently lies about the doing of other people and tries to manipulate other people s minds by scaring them. The root of all Abigails wrong doings come from her unjust motivations, which has to do with her lust for John Proctor. Even though John is married to Elizabeth, she still wants John and is willing to do anything for it. She even says to him, John- I am waitin for you every night. (22). She also continues to fantasize about her relationship (mainly fueled by lust) with John Proctor. In front of Betty while she was unconscious she said to John, I know how you clutched my back behind your house and sweated like a stallion whenever I come near! Or did I dream that? Its she put me out, you cannot pretend it were you. I saw your face when she put me out, and you loved me then and you do now. (23) Abigail even ventures as far as to beg John to talk about his affection for her. She begs, Give me a word, John. A soft word. (23). All of her lies, sins, and vengeful feelings for Mrs. Proctor are consequential of her love and lust for John Proctor. Abigail Williams is a villain who is fueled by the motivations of lust for John Proctor, which brings out her manipulative strength and lying abilities. All the things that Abigail Williams did during the crucible, caused harm, uproar, and eventually death for a lot of people. If thats not a villain, what is?

Cloud Point Extraction Experiment
Cloud Point Extraction Experiment Bromothymol blue (also known as bromothymol sulfone phthalein, BTB) (Figure 2.1.1) is a pH indicator (yellow at pH 6.0 and blue at pH 7.6). Its chemical name is: 4,40-(1,1-dioxido-3H-2,1-benzoxathiole-3,3-diyl)bis(2-bromo-6-isopropyl-3-methylphenol (The Merck Index, 13th edition, 2007)[1]. pKa of BTB is 7.1. This dye is the most appropriate pH indicator dye in physiological tissue and also used in the investigation of the interaction of lipid with protein (Puschett and Rao 1991; Gorbenko 1998; Sotomayor et al. 1998)[2,3,4]. It is widely applied in biomedical, biological, and chemical engineering applications (Schegg and Baldini 1986; Ibarra and Olivares-Perez 2002)[5,6]. BTB in protonated or deprotonated form is yellow or blue in color, respectively, while its solution is bluish green in neutral solution. It is sometimes used to define cell walls or nuclei under the microscope. BTB is mostly used for the evaluation and estimation of the pH of pools and fish tanks and the determinatio n of the presence of carbonic acid in liquid. There are several treatment procedures for dyes from waste materials, including adsorption (Nandi, Goswami, and Purkait 2009)[8], coagulationââ¬âflocculation, oxidationââ¬âozonation, reverse osmosis, membrane filtration, biological degradation, and electrochemical processes (Shen et al. 2001; Kim et al. 2004; Chatterjee, Lee, and Woo 2010)[9,10,11]. 2.1.2 EXPERIMENTAL 2.1.2.1 Materials: All the solutions were prepared with double-distilled water. 2.1.2.1.1 Triton X ââ¬â 100 (0.1M): Triton X-100 was purchased from Qualigens Analytical grade. The TX-100 was cleared of any low-boiling impurities by exposure to vaccum for 3h at 700C following the procedure given by Kumar and Balasubrahmanium[19]. 31.4 g of TX-100 liquid is dissolved 500 ml volumetric flask and made up to the mark to obtain 0.1 mol/dm3 solution. The critical micellar concentration and Cloud point of TX-100 are 2.8Ãâ"10âËâ4 [20] 65à ¢-à ¦C [21] respectively. 2.1.2.1.2 Bromothymol Blue (BTB) : 1.0 g of BTB dye Merck India was dissolved in 5.0 ml of ethanol (99.8%) for dissolution then dilution are made with double distilled water into a 1000 ml volumetric flask up to the mark to obtain an concentration of 1000 mg/dm3(Babak Samiey, Kamal Alizadeh et.al 2004)[22]. In order to avoid fading stock solution was wrapped black color paper. The working solutions of BTB were prepared by appropriate dilutions of the stock solution immediately prior to their use. 2.1.2.1.3 Acetic acid (0.5M). 28.5 ml glacial acetic acid (A.R.grade) Qualigens was diluted with distilled water in a 1000 ml volumetric flask to give 0.5M Acetic acid solution. The solution obtained was diluted to required concentration and standardized as per the procedure (Vogel et. al. 1989)[23] with standard NaOH solution. 2.1.2.1.4 Sodium acetate (0.5M): 13.6 g sodiumacetate.trihydrate, (CH3COONa.3H2O) of Analytical grade Qualigens is dissolved in 100 ml volumetric flask and made up to the mark (Vogel et. al. 1978)[24]. 2.1.2.1.5 NaCl (0.1M): 2.922 g pure dry salt of sodiumchloride of analytical grade Qualigens is weighing out and dissolved in 500 ml volumetric flask to give 0.1M NaCl solution(Vogel et. al. 1989)[25]. 2.1.2.1.6 Na2SO4 (0.5M): 16.1 g of sodiumsulphate decahydrate,(Na2SO4.10H2O) A.R.grade from Merck (India), is dissolved in 100 ml volumetric flask and made up to the mark to give 0.5M Na2SO4 solution(Vogel et. al. 1989)[26]. 2.1.2.1.7 KH2PO4(1.0M): 34.02 g of KH2PO4 of Analytical grade Qualigens is dissolved in 250 ml volumetric flask and made up to the mark (Vogel et. al. 1978)[27]. 2.1.2.1.8 Na2HPO4 (1.0M): A.R. grade disodium hydrogen phosphate, Na2HPO4.2H2O, is taken in porcelain crucible and heated until no more water is liberated. Then 17.8 g of this cold residue is taken in 100 ml volumetric flask and made up to the make to give 1.0 M of Na2HPO4 solution (Vogel et. al. 1978)[28]. The reagent is prepared freshly each time. 2.1.2.1.9 Buffer solution of pH4.0(à ±0.05): 5 ml of 4M sodium acetate (A.R. grade) Qualigens and 20 ml of 4M acetic acid (A.R. grade) Qualigens are mixed in an 100ml volumetric flask and made up to the mark which has resultant pH of 4.0(à ±0.05) (Vogel et. al. 1989)[29] . 2.1.2.1.10 Buffer solution of pH5.0(à ±0.05):: 17.5 ml of 4M sodium acetate (A.R. grade) Qualigens and 10 ml of 4M acetic acid (A.R. grade) Qualigens are mixed in an 100ml volumetric flask and made up to the mark which has resultant pH of 5.0(à ±0.05) (Vogel et. al. 1989)[30] . 2.1.2.1.11 Buffer solution of pH6.0(à ±0.05): 13.2 ml of1M KH2PO4 (A.R.grade) Qualigens and 86.8 ml of 1M Na2HPO4 (A.R.grade) Qualigens are mixed in 100ml volumetric flask which has resultant pH of 6.0(à ±0.05) (Vogel et. al. 1989)[31]. 2.1.2.1.12 Buffer solution of pH7.0(à ±0.05): 61.5 ml of 1M KH2PO4 (A.R.grade) Qualigens and 38.5 ml of 1M Na2HPO4 (A.R.grade) Qualigens are mixed in 100ml volumetric flask which has resultant pH of 7.0(à ±0.05) (Vogel et. al. 1989)[31]. 2.1.2.1.13 Buffer solution of pH8.0(à ±0.05): 94.0 ml of 1M KH2PO4 (A.R.grade) Qualigens and 6.0 ml of 1M Na2HPO4 (A.R.grade) Qualigens are mixed in 100ml volumetric flask which has resultant pH of 8.0(à ±0.05) (Vogel et. al. 1989)[31]. 2.1.2.1.14 Buffer solution of pH9.2(à ±0.05): 1.905g of Na2B4O7.10.H2O of (A.R.grade) Qualigens is dissolved in 100ml volumetric flask and made up to the mark to obtain 0.05 M of borax solution.The resultant pH of the solution is 9.2(à ±0.05) (Vogel et. al. 1989)[32]. 2.1.2.2 Methodology for cloud point extraction: 2.1.2.2.1 Procedure: The cloud point temperature was determined by literature method reported by Carvalho et al. [33]. This is based on the ââ¬Ëvisual observation of the separation of phasesââ¬â¢ in the micellar solution. The solution was heated gradually in the water bath until turbidity appeared. To verify the results, the opposite process was carried out by cooling gradually with constant stirring and the cloud point was considered as the temperature at which the solution became clear. The reported value was the average of these two determinations; in most cases, these two temperatures were identical, within + 0.5oC. Cloud point extraction experiment was conducted by using a 10 ml centrifuge tube with a screw cap containing different concentrations of Triton X-100 and BTB and sonicated for 2 minutes for proper mixing. The solution is heated up to 80Ãâ¹Ã
¡C in a thermostatic temperature bath for 20 min. The turbid solution was then centrifuged at 3500 rpm for 5 min and cooled in an ice bath for 2 minutes in order to separate the phases. Both the phases are separated and the volumes of surfactant rich phase (coacervate phase) and dilute phases were measured. Average of three determinations is reported in all cases. The concentration of dye in both the phases has been measured by using PerkinElmer lamda-25 UV-Visible spectrophotometer. In order to determine the influence of the reagents added to the surfactant phase, cloud point determinations were performed with the additions of buffer, dye and inorganic salts. The procedure for the determination of critical temperature was the same as above, bu t using only a fixed surfactant concentration. The phase diagram for Triton X-100 was obtained by measuring the cloud point temperature of aqueous surfactant solutions at different concentrations. 2.1.2.2.2 Spectra and calibrated graph The concentration of the dye was determined by U.V-visible spectrophotometer (PerkinElmer lamda-25). Pure BTB was initially calibrated separately for different concentrations in terms of absorbance units, which were recorded at wavelength 430 nm, at which maximum absorption takes place (Figure 2.1.2, 2.1.3). No significant change in the absorbance has been observed even in the presence of TX-100. Therefore all the absorbance measurements were performed at this wave length. Figure 2.1.2 Spectra of BTB dye Figure 2.1.3 Calibration curve of BTB dye 2.1.2.2.3 Determination of Phase volume Ratio, Fractional coacervate phase volume and pre-concentration factor The volumes of the respective surfactant-rich and aqueous phases obtained after the separation of phases were determined using calibrated centrifuge tubes for calculating the pre concentration factor. Surfactant solutions containing typical amounts of the BTB were extracted using the CPE procedure, followed by the measurement of the respective phase volumes. The results reported are the average of three determinations. The phase volume ratio is defined as the ratio of the volume of the surfactant-rich phase to that of the aqueous phase. It is calculated using the following formula. (2.1.1) Where RV is the phase volume ratio, VS and VW are volumes of surfactant-rich phase and aqueous phase respectively. The pre-concentration factor, (fC) is defined as the ratio of the volume of bulk solution before phase separation (Vt) to that of the surfactant-rich phase after phase separation (Vs). (2.1.2) Where Vt and VS are the volumes of the bulk solution before phase separation and the surfactant-rich phase respectively. The fractional coacervate phase volume with the feed surfactant concentration is calculated by using the relationship: (2.1.3) Where FC is the fractional coacervate volume and Cs is the molar concentration of the feed surfactant solution, for fixed feed dye concentration, the parameters a and b vary linearly with temperature. The value of Fc lies in between 0.04-0.23 for various operating conditions. Surfactant partition coefficient (m) is defined as the ratio of concentration of surfactant in coacervate and dilute phase. - (2.1.4) The efficiency of extraction is defined as - (2.1.5) 2.1.4 Discussion: This section is divided into four parts. In first part, factors influencing the extraction efficiency (e.g., concentrations of non-ionic surfactants, dye and salt, temperature and pH of the solution), fractional coacervate phase volume have been discussed. The nature of solubilization isotherm at different temperature has been presented in the second part. In the third and fourth parts, thermodynamic parameters and a calculation procedure for the determination of surfactant requirement for the dye removal to a desired level is briefly discussed. 2.1.4.1 Factors influencing efficiency: For ionizable solutes, the charge of the solute can greatly influence its extent of binding to a micellar assembly [34]. The ionic form of a molecule normally does not interact with and bind the micellar aggregate as strongly as does its neutral form. Thus adjustment of the solution pH for maximum extractability is of special importance when controlling experimental variables in CPE. With increasing pH, the efficiency of extraction increases up to pH 8.0 and then decreases. This is in accordance with the decrease in cloud point till pH 8.0 and a sudden increase at pH 9.2. Further, the pK value of BTB is 7.1. In the absence of any buffer solution, pH of the dye solution is 7.0 and there is no change in pH event after the extraction process is completed. Hence, all the parameters were optimized at this fixed pH of the medium. No significant increase in efficiency is observed with increasing [Dye] since the cloud point is not altered much with increasing the concentration of dye. The extraction efficiency of dye increases with the increase of surfactant concentration. The concentration of the micelle increases with the surfactant concentration, resulting in more solubilisation of dye in micelles. The surfactant concentration in the dilute phase remains constant (and equal to around CMC); the surfactant concentration along with the solubilised dye in the coacervate phase (micellar phase) increases to maintain the material balance[42-46]. The extraction of dye with TX-100 solution is due to hydrophobic interaction between BTB and hydrophobic micelles in the solution. However, with the increase of TX-100 concentration, the analytical signal becomes weak due to the increase in the final volume of the surfactant rich phase that causes pre concentration factor (phase volume ratio) to decrease [35]. In view of these observations, a 0.04 mol/dm3 triton X- 100 is used throughout. It has been shown that the presence of electrolyte can change the CP in different ways[36]. Salting out electrolyte such as NaCl, decreases the cloud point temperature. They can promote the dehydration of ethoxy groups on the outer surface of the micelles, enhancing the miceller concentration leading to solubilisation of more dye and resulting in a more efficient extraction [37] and reduce the time required for phase separation. A lower salt concentration gives a smaller pre concentration factor, due to the larger volume in the surfactant-rich phase at lower salt concentrations [38]. As shown in the fig the ability of salts to enhance extraction efficiency of the dye was in the order of Na2SO4>NaCl. Temperature has pronounced effect on the extraction of solute. (i) At high temperature, CMC of non-ionic surfactant decreases. (ii) the non-ionic surfactant becomes more hydrophobic due to dehydration of ether oxygen [39] and increase in micellar concentration and solubilization. A general preconcentration factor of 20-60 was obtained with this CPE method and similar pre concentration has been reported for other analytes (40). Typical preconcentration factors reported in the literature[41] varà ¯ed fiom 10 to 100. The CPE method gives a better preconcentration factor compared to conventional solvent extraction methods. In general, high pre concentration factors in CPE can be achieved using small amounts of surfactants which have large capacity to accommodate dye molecules. The hydrated nature and relative polarity of micelles, on the other hand, limit the extraction of dye into the surfactant-rich phase. From the viewpoint of concentrating the analytes present in aqueous solutions, the larger pre concentration factor, e.g., the smaller phase volume in the surfactant-rich phase is desired. A lower surfactant concentration gives a higher pre concentration factor. However, it becomes very difficult for sampling and accurate analysis with a very small volume of the surfactant-rich phase. On the contrary, excessive amount of added salt of ââ¬Å"salting-outâ⬠effect can give the higher pre concentration factor, but it is likely forming the very viscous liquid crystalline phase, instead of the fluidic Liquid phase, in the system, making it difficult to separate the surfactant-rich phase. Therefore, optimization of the pre concentration factor is very critical in a feasible CPE technique. Hence, surfactant concentration of 0.04 mol/dm3 was chosen to conduct CPE experiments in this research. 2.1.4.2 Solubilization isotherm: The adsorption isotherm relating moles of solute solubilized per mole of surfactant[50] are presented in Figure2.1.8. The isotherm can be expressed according to Langmuir type expression: (2.1.6) Where, both m and n are functions of temperature. Figure 2.1.8 Solubilisation curve of BTB dye Assuming a homogeneous monolayer adsorption, the linearized Langmuir sorption model of equation (2.1.6) can be written as: (2.1.7) Plot of 1/qe vs. 1/Ce over the entire dye concentrations was linear with a correlation coefficient of 0.983 as shown in Figure 2.1.9. Thus, the solubilization of dye obeys the Langmuir adsorption model. The calculated values of Langmuir parameters m and n from the slope and intercept of the linear plot of 1/qe vs. 1/Ce were found equal to 4.29X 10-3 (mol/mol) and 2.04X104 dm3 /mol, respectively. Figure 2.1.9 Langmuir isotherm of BTB dye 2.1.4.3 Thermodynamic parameters: The overall thermodynamic parameters ÃâG0, ÃâS0 and ÃâH0 were calculated using equations (2.1.8, 2.1.9) [48,49]as follows. (2.1.8) - (2.1.9) Where T is the temperature in (K), qe/Ce is called the solubilization affinity. ÃâS0 and ÃâH0 are obtained from a linear plot of log (qe/Ce) versus (1/T), from Eq. (2.1.8) and. Once these two parameters are obtained, ÃâG0 is determined from Eq. (2.1.9) and presented in Table 2.1.6. Plot of log (qe/Ce) versus (1/T) is shown in Figure 2.1.10.

(2.1.10) Moles of dye solubilized can be obtained from mass balance equation, (2.1.11) (2.1.12) Where, A is the moles of dye solubilized in the micelles, V0 and Vd are the volume of the feed solution and that of the dilute phase after CPE, C0 and Ce are concentration of the BTB dye after CPE respectively; Cs is the concentration of surfactant in feed. From the equation 2.1.10, 2.1.11 and 2.1.12 we can write, (2.1.13) Moles of dye solubilized can be obtained from mass balance equation, Where, qe is the mole of dye solubilized per mole of non-ionic surfactant, x is moles TX-100 used, A is the moles of dye solubilized in the micelles, V0 and Vd are the volume of the feed solution and that of the dilute phase after CPE, C0 and respectively; Cs is the concentration of surfactant in feed. (2.1.14) Now, by involving the definition of fractional coavervate volume in the above equation we get, (2.1.15) - (2.1.16) Where a,b are the parameters a and b which are functions of temperature. Substituting the above equation in equation (8) we get, - (2.1.17) Substituting the above equation in equation (1) and rearranging we get, (2.1.18) From the above equation the desired surfactant required (Cs) can be obtained knowing the value of m and n the Langmuir constants, a and b the operating temperature constants, Ce the amount of dye in dilute phase after cloud point extraction.

Executive Summary The Sun Products Corporation has designed a product that offers buyers an easy and affordable way to effectively soften their laundry. Proper fabric softening is the most effective process available to reduce static cling and stiffness in clothing. Improper laundry techniques result in wrinkles, faded materials, and the breakdown of fabrics. Studies have shown that proper washing procedures can slow down the deterioration of fabrics and lengthen the life of clothes while making the whites whiter and colors brighter over a longer period of time. The greatest solution to this problem stems from the lack of use of fabric softeners. Existing products offer no effective or affordable solutions for ensuring laundry comes out soft and snuggly. Treatment of clothes costs Americans over $4 Billion in direct costs each year. The Sun Products Corporation is the first line of laundry products to answer this problem and provide proven results that using fabric softener lengthens the overall life and quality of clothing.

Meeting deadlines is always tough in a long developmental process, and so thanks are in order to those that helped me prepare and deliver manuscript on time. Finally, I could not have accomplished all that was expected without that special patience and understanding that only a family can give. INTRODUCTION The process of management involves planning, organizing, directing and controlling people and activities. At each level of management, the responsibilities for handling these tasks differ. Top-level managers are responsible for establishing organizational objectives. Middle-level managers organize and control the organizationââ¬â¢s resources to achieve these objectives, whereas lower-level managers supervise day-to-day activities. Each of these three levels of management has distinct information systems needs. First line supervisors require feedback about day-to-day activities. Middle level managers need information that will enable them to reallocate resources to achieve objectives. Top-level managers use external information to identify new business opportunities and to establish goals for the firm. This assignment helps us to understand information systems that support management decision-making at the operational, tactical and strategic planning levels.
