My Goals for the Future free essay sample

What you get by achieving your goals is not as important as what you become by achieving your goals†- Henry David Thoreau. Making and achieving goals is so important in one’s life, because once you have achieve them it makes you a better person. Achieving goals make you feel confidence in yourself, and it gives you the sense of accomplishment. Like the quote says it’s not about what you get from achieving your goals it’s about what you become by achieving your goals. I was always a person who had very high goals because I felt that the higher they are, the harder I will work to achieve them. After high school I will be attending Clemson University in the Call Me Mister Program and one of my goals is to become a great teacher. Every since I was in middle school I always felt that education was my calling, because I love to talk and help others. We will write a custom essay sample on My Goals for the Future or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Now as a high school senior I have start working towards my goal by entering the teacher cadet class where I am in the classroom with students. Being in this program has really brought me closer to the education field. I have learned that becoming a teacher is not just about teaching, but it’s about mentoring and loving your students. Teaching is a way to aid parents with the upbringing of their children. I believe that being a part of the Call Me Mister program will most definitely help me reach my goal, because â€Å"Mister† means Mentors Instructing Students Toward Effective Role Models which is one of their main priority. Another goal of mine is to become a Principal. I feel that one should never stop at just one goal; there should always be others in place. Once I reach my first goal to become a teacher; I will strive to become an effective Principal. Being a principal will give me the authority to help all students be successful. Becoming a principal would give me the lead away of putting my school on the map. Being the strong, family oriented leader that I am, I can do many things as a principal. I see myself coming back to Elloree and making a difference. I want all of Elloree children to have the same opportunities and even more than what I had. I want the parents of the students to feel proud of their children, because of something positive. I want to knit elloree back together as a family. I have many goals, but these are some that benefit my community and me. It is great that the citizens of Elloree give out a scholarship to students in the community. It gives me joy to see that there are people in my community that do care about my education and my future. That why I feel that it is my duty to come back to my community and help other students achieve their goals. It takes only a few people to help a child on their way to success. With this scholarship some of my goals can be accomplish. Every penny counts when education is the key. Making and achieving goals is so important in one’s life, because once you have achieve them it makes you a better person. Every child’s life should be fill with goals and dreams. And with that said, there should be adults out there to make sure that every child goals and dreams are fulfill. It only takes one person to start it off. With GOD on my side, I will do what is possible to achieve my goals. Achieving is believing and once you believe that you can do it, it will be done.

England and Ireland essays

England and Ireland essays To understand this current situation, we will have to go back in history. There are three critical dates which lead to the situation today. Those dates are: 1170, 1609, and 1969. In the next paragraphs I will briefly explain what was going on in each of these years. To begin with, in 1170, Henry II ruled England. He attempted to attach Ireland to his kingdom. However, he only established control in a small area near Dublin known as the Pale. In that particular area, English citizens started moving in and adapting the English language, religion, practices, beliefs, and etc. Attempts were made to conquer the rest of Ireland, but major English expansion did not take place until the seventeenth century. In 1609, Queen Elizabeths army had established the English rule over most of the island of Ireland, with the exception of the Northern Province: Ulster. The Ulster clans (Lead by Hugh ONeil) had a very affective alliance against the English army. Unfortunately, after a long and damaging campaign, it was eventually brought under English control in 1703. By then, all the Irish leaders had left Ireland for Europe, and less than 5% of Ulster was controlled by Catholics Irish. Later on, in 1969, the restlessness in Northern Ireland really started. In this year, the minority demanded better job opportunities, accommodation, and rights for voting. In reaction to this, the British government introduced a new law which prohibited religious discrimination and cancelled the law of 1922. In reaction to that, in the 1970s, the IRA (Irish Republic Army) began their terrorist reactions. The problems in Northern Ireland are practically from the difference in religion. There are two main camps, the Unionists and the Republicans. The Unionists are Protestant Christians, and the Republicans are Catholic Christians. Northern Ireland was created by the English as an attempt to stop the fighting. The idea was that as the Protestants...

Buddhist And Christian Ethics Theology

Buddhist And Christian Ethics Theology Buddhism and Christianity are religions with comprehensive and contrasting ethical laws and customs. Throughout this essay the ethical practices of both religions will be described in detail, with an exploration of their similarities and differences presented. Description of Buddhist Ethical Practices Seven weeks after Prince Siddhartha Gautama had attained enlightenment whilst meditating under a bodhi tree, he delivered his First Sermon to his five former ascetical companions under that same tree. The contents of that initial sermon are knows as the Four Noble Truths, which are essentially the foundation of the religion. They are as follows: (Gwynne 2011, p. 93) â€Å"1. Suffering: Now this, monks, is the noble truth of suffering: Birth is suffering, ageing is suffering, sickness is suffering, death is suffering; union with what is displeasing is suffering; separation from what is pleasing is suffering; not to get what one wants is suffering; in brief, the five aggregates subject to clinging are suffering. 2. The Source of Suffering: Now this, monks, is the noble truth of the origin of suffering: It is the craving which leads to renewed existence, accompanied by delight and lust, seeking delight here and there; that is, craving for sensual pleasures, craving for existence, craving for extermination. 3. The Cessation of Suffering: Now this, monks, is the noble truth of the cessation of suffering: It is the remainder-less fading away and cessation of that same craving, the giving up and relinquishing of it, freedom from it, and non-reliance on it. 4. The Way to the Cessation of Suffering: Now this, monks, is the noble truth of the way leading to the cessation of suffering: It is this Noble Eightfold Path: that is, right view, right intention, right speech, right action, right livelihood, right effort, right mindfulness, and right concentration.† Like its parent religion Hinduism, Buddhism teaches that the ultimate goal of the lives of adherents is to bre ak free from the wheel of reincarnation and attain nirvana. Where it differs from Hinduism is instead of stressing the importance of obligations related to caste, gender and age (varna ashrama dharma), it stresses the embodiment of the sublime truth that was rediscovered by Prince Siddhartha on his night of enlightenment, which was imparted to his early followers in his First Sermon. The essence of Buddhist dharma (as opposed to Hindu dharma) is the Four Noble Truths which, along with the Buddha himself and the community of adherents (Sangha), make up the Three Jewels of Buddhism. The last of the Four Noble Truths, the Noble Eightfold Path, is often divided into three categories: 1. Wisdom (panna) – right view and right intention 2. Meditation (samdhi) – right effort, right mindfulness and right concentration 3. Virtue (sila) – right speech, right action and right livelihood. This category specifically provides ethical instruction for Buddhists, insisting that a dherents must refrain from abusive, deceitful or divisive words through right speech; calling buddhists to be generally righteous in their actions; and implying that certain occupations may be immoral and hence unsuitable. (Gwynne 2011, pg. 92) Buddhism lacks a clear belief in a supreme being, resulting in Buddhist morality being based upon the degree as to which thoughts and actions will advance or impede one’s quest for final liberation. It is not based upon commandments issued by a transcendent God which are to be unquestionably followed by adherents, as is the case in the Abrahamic religions. Without a God to dictate what is good and evil, Buddhists refer to certain actions as â€Å"skillful† (kausalya) or â€Å"unskillful† (akausalya) rather than right or wrong. Buddhist morality is based upon considerations of individual progress on the road to liberation from the wheel of reincarnation rather than practicing the will of a divine God.

Critical Thinking Essay Example | Topics and Well Written Essays - 1500 words

Critical Thinking - Essay Example 3. The production of wealth is mainly based on the exploitation of the earth’s natural resources. Unchecked exploitation of these finite resources is an off-shoot of the need to engender wealth, and leads to imbalances in the ecosystem. Conversion of these natural resources into manufactured consumer goods often uses technology which causes pollution and global warming. In this context, economists tend to ignore the environmental problems which accompany economic growth. This puts them in direct confrontation with environmental scientists who are concerned with the protection of the environment. 4. (a) Environmental issues, such as clean air, conservation of wildlife, and green energy, cannot be judged in purely monetary terms. While clean air cuts medical costs due to lung disorders, and green energy, such as more efficient refrigeration techniques, can reduce wastage and energy bills, it is more difficult to define the benefits of wildlife conservation in financial terms. Lo ve of wildlife involves social and emotional aspects which cannot be quantified. (b) I would be prepared to pay about five percent of my income towards environmental issues. 5. The question in the title is, â€Å"Why do economists and environmental scientists have such a hard time communicating?†... 7. (a) The problem defined in the essay is the irreconcilable difference in attitude between economists and environmental scientists in assigning monetary values to environmental goods. (b) The proposed solution is to assign monetary values to environmental goods, so that there can be trade-offs between the competing needs of wealth generation and environmental protection. (c) The writer doubts that an agreement can be reached between economists and environmentalists, as the latter will not accept the assignment of a cash equivalent, however large, to environmental goods or agree to a cap on environmental spending. 8. Summary of Article 1. The article, â€Å"Never the Twain Shall Meet: Why do economists and environmental scientists have such a hard time communicating?† deals with the wide gap in the perspectives of economists and environmentalists. While economists firmly believe that environmental goods can be reduced to cash equivalents, this idea is anathema to environmenta lists. Economists argue that by assigning monetary values to environmental goods, such as clean air and biological diversity, compromises can be made to achieve a balance between the consumption of these goods and environmental protection. The writer declares that it is inevitable that monetary values be assigned to environmental goods, so that a policy can be formulated and choices can be made regarding the consumption of such goods. Philip Graves, an economist, states that environmental goods are substantially undervalued by economists using standard methods of measurement. He contends that there will be a significant difference in the amount consumers would spend on environmental goods if they were actually available on the market, and the amount they give as a theoretical estimate.

Social Networking Essay Example for Free

Social Networking Essay A social networking service is an online service, platform, or site that focuses on facilitating the building of social networks or social relations among people who, for example, share interests, activities, backgrounds, or real-life connections. There are dating sites, friendship sites, sites with a business purpose and hybrids that offer a combination of these When it comes to online social networking, websites are commonly used. These websites are known as social sites. Social networking websites function like an online community of internet users. Depending on the website in question, many of these online community members share common interests in hobbies, religion, politics and alternative lifestyles. Once you are granted access to a social networking website you can begin to socialize. This socialization may include reading the profile pages of other members and possibly even contacting them. A social network service consists of a representation of each user (often a profile), his/her social links, and a variety of additional services. Most social network services are web-based and provide means for users to interact over the Internet, such as e-mail and instant messaging. Online community services are sometimes considered as a social network service, though in a broader sense, social network service usually means an individual-centered service whereas online community services are group-centered. Social networking sites allow users to share ideas, activities, events, and interests within their individual networks. Social networking establishes interconnected Internet communities sometimes known as personal networks that help people make contacts that would be good for them to know, but that they would be unlikely to have met otherwise. In general, heres how it works: you join one of the sites and invite people you know to join as well. Those people invite their contacts to join, who in turn invite their contacts to join, and the process repeats for each person. In theory, any individual can make contact through anyone they have a connection to, to any of the people that person has a connection to, and so on. The main types of social networking services include: a) Facebook is the world’s largest social network, with more than 900  million users. Mark Zuckerberg founded Facebook in 2004 while he was attending Harvard University. b) Google+, a social network operated by Google, Inc., launched on June 28th, 2011 with integrations across a number of Google products, including Buzz and Profiles. c) Twitter is a free microblogging service founded in 2006 by Jack Dorsey and Biz Stone. At its heart are 140-character bursts of information called tweets. Users can include links to other content in their tweets, and broadcasts can be public or private. d) YouTube was founded in February 2005 and has become the go-to site for video on the web. One hour of video is uploaded to YouTube every second. e) WhatsApp Messenger is a cross-platform instant messaging application available only to the smartphones: iPhone, BlackBerry, Android and Symbian. In addition to normal texting, WhatsApp Messenger users can send each other images, video and audio media messages, as well as engage in group conversations between multiple users. Social networking has some benefits for example you are able to make friends. Another one of those benefits includes diversity because the internet gives individuals from all around the world access to social networking sites. This means that although you are in the United States, you could develop an online friendship with someone in Kenya. Not only will you make new friends, but you just might learn a thing or two about new cultures or new languages and learning is always a good thing. Social networking also has some disadvantages associated with it, for example employers can use information on social sites to learn about prospective employees. Reading profiles and perusing photos has become standard for human resources departments in some companies. Ones job search could be affected accordingly. Most of this sites are also addictive and this can affect your studies if you are student and affect your job if your are working. There are dangers associated with social networking including data theft and viruses, which are on the rise. The most prevalent danger though often involves online predators or individuals who claim to be someone that they  are not Social site trend is growing very first and currently we have cellphone application. The cellphone potential for socializing is growing all the time, and mobile features allow users to continue their experience when away from home, school or office. The GPS feature built into many smartphones adds the twist of knowing where friends are at any given moment. Social networking will remain relevant to those who are willing to continue learning as new techniques come out and also new services are developed. This is because looking at the current trend in technology there is a high speed growth in this field.

Phoenix Jacksons Story in A Worn Path :: essays research papers

"Little by little, one walks far." Peruvian Proverb As this cherished saying from Peru is implying, great things never happen in single leaps. It takes small steps, and plenty of determination, to get to the end. Phoenix Jackson, an elderly African-American, is a great example of this proverb as she walks that long distance to town, determination in her every step. Even in her old age Phoenix is a shining example of what can be accomplished with determination. Phoenix?s unwavering determination is clearly evidenced in her reaction to the dog, in her meeting with the hunter, and in her personal battle of age. One aspect of determination is the bravery to keep going no matter what may happen, which Phoenix displays often throughout the story. When Phoenix was attacked by a large black dog on her way to town, the elderly woman was unfazed. While some people would have panicked, Phoenix simply laid ?there and presently went to talking. ?Old woman,? she said to herself, ?that black dog come up out of the weeds to stall you off, and now there he sitting on his fine tail, smiling at you??. Phoenix?s reaction to the dog was one of good humor, which shows that even though she was startled, she was not flustered in the face of danger. After being tackled by the large dog, a hunter with a dog of his own comes along and rescues the Phoenix. After the hunter had shooed the large dog away, he pointed the barrel of his gun directly at Phoenix. She was unfazed and if anything she stood up straighter. When the hunter asked if the gun scared her, she replied, ?No, sir, I seen plenty go off closer by, in my day, and for less than what I done.? Phoenix?s bold statement hints at her probably tragic past, which undoubtedly shaped her to become the woman she is today. Determination alone is not enough to accomplish a task. Motivation is needed as well. For Phoenix, she has her grandson, who needs medicine from town or else he could not breathe. At the doctor?s office, the nurse explained to the attendant the ?she doesn?t come for herself- she has a little grandson. She makes these trips just as regular as clockwork.? Phoenix, even in her old age, travels that long way in every kind of weather, just to ensure her young grandson?

Safeguarding And Forms Of Abuse

I am going to briefly talk bout the main types of abuse and outline a general picture about safeguarding. I will then focus on two types of abuse and explain them in more detail, giving examples of real life events. Safeguarding is? Safeguarding means protection against something undesirable. Everyone has the responsibility to safe guard children and young people. The Government and safeguarding legislation guidance says that safeguarding means: Protecting children from maltreatment. Preventing impairment of children's health or development.Ensuring that children are growing up In circumstances consistent with the provision f safe and effective care. Taking action to enable all children and young people to have the best outcome. â€Å"the action we take to promote the welfare of children and protect them from harm ; is everyone's responsibility. Everyone who comes into contact with children and families has a role to play. † Types of Abuse Deprived of health benefits – this is when a abuser will stop a victim from getting any form of help such as seeing a doctor, a dentist or attending an appointment.The abuser me see that the victim doesn't require that specific attention because they may see the victim as not worthy or special. They may also think that the Injuries the victim has may become noticed and be looked Into leading to the abuser being found out and reported. Physical abuse- this Is when an abuser physically Injuries a volt such as halting and cackling them or anything where the abuser Inflicts pain on the victim. This abuse is a form of excitement for the abuser as they have control over the victim.People may also hit out through stress or maybe due to losing their temper but there are lots of other reasons. This specific abuse will include the abuser hitting the victim in some way to get what they want from them and to keep hey grounded and under control by striking fear into the victim. Verbal abuse- this is when a abuser will say th ings to a victim to make them feel bad about themselves. This can result in the victim going on to act in a bad way such as saying verbal abuse to others therefore repeating the abusers words.This abuse is used to make others feel bad about themselves so that the abuser can feel good about them self. Emotional abuse – this can be linked In with any other form of abuse as the volt will be feeling certain things and In a certain way. Emotional abuse is where a abuser ill try to break the volt down emotionally resulting In the victim feeling bad about themselves all the time and the abuser being able to get inside a victim's head bad at what they do or how they act or making a victim feel bad inside constantly.Financial abuse- this form of abuse is when a abuser will take money from a victim, whether the victim knows or not is a different matter. An abuser may simply steal money from a victim by going into their purse or wallet and taking money or by doing it in a sneaky manner such as borrowing money or playing the victim to a game which they won't win. Sexual abuse- this form of abuse includes when a abuser will touch a person in a sexual manner without being given consent by the person to do it such as touching breasts or genitals.Sexual abuse can also include rape this is when the person hasn't or cannot consent to sex but the abuser continues to do the act. Psychological abuse- this is when the abuser will try to get inside the head of a victim so they can obtain what they want or get the victim to do or say what they want this will allow the abuser to convince the victim that it is k to be doing this to them. Neglected- this is a form of abuse where the abuser will not let the victim have food, water, hygiene or medical attention and they will make sure that no one else allows those things to happen.The abuser may also stop a victim for Joining in with things or being in a group with people they would like to socialist with. This form of abuse leaves the victim to survive on their own without having any means to survive with. Bullying- bullying is when a abuser will use any of the forms of abuse to make a person or a group of people feel bad. Emotional, verbal and physical abuse are molly linked with bullying as they can make a person feel bad about themselves rather quickly and easily. Physical abuse I am now going to focus on two types of abuse which are physical abuse and self harming.Physical abuse is any form of pain which is inflicted on a person and is done on a daily basis. Hurting someone in an intentional way is physical abuse. This form of abuse may consist of many things such as: Scratching Head butting Shouting Drowning Dragging Around Sleep Deprivation Throwing Outside/Locking Outside Putting in stress positions Blinding (Blindfolding) scolding Cutting Kneeing Strangling Hitting Pushing Pulling Hair Biting Physical abuse allows them to control someone as the abusers strike fear into their victims leading them to d o, say and act like the abuser wants them to.Physical abuse took place in Long Care (Stoke Place), here the patients were physically abused by their careers. This involved them being slapped, kicked and hit on a daily basis to control them into doing as the careers wished or to prevent them from doing something. Self harming Self-harm is when someone intentionally hurt themselves by damaging or injuring heir body and is used as a way to deal with or express emotional distress.In most cases people who self harm do it to help them to deal with overwhelming and unbearable emotional issues which are caused by problems such as: Social factors- like being bullied, having difficulties with work or school or having difficult relationships with friends or family. Trauma- such as physical or sexual abuse or the death of a close family member or friend. Mental health conditions- such as depression or borderline personality disorder. Self harming is a lot more common than people realism and can take part in any person's life.It is more common to appear in the lives of 15 and 16 years old as in 2002 a I-J survey showed an estimate that 10% of girls and 3% of boys had self harmed in the previous year. In some cases people self-harm with the intension to kill themselves but often people self harm to punish their selves, express distress or to relieve tension. Self harming can also be seen as a cry for help in some cases. Types and signs of self harm – There are many ways that people can intentionally harm their selves such as: Cutting or burning their skin Punching themselves Poisoning themselves with things such as tabletsMisusing alcohol or drugs Deliberately starving themselves (anorexia nervous) or binge eating (bulimia nervous) People who self harm will keep it a secret as they fear the shame of discovery; therefore it is often up to family or friends to notice when someone is self harming and for them to approach them with understanding and care. Some sign may i nclude unexplained injuries or a person may show signs of a low self esteem or even depression. Someone who is self harming could seriously hurt themselves and should therefore be referred to a doctor so that they can discuss the underlying sue and find a way of treatment and therapy to help them.The events such as physical, sexual and emotional abuse that took place at places such as Long Care (Stoke Place), Wintergreen view and Stafford Hospital (Mid-Staffordshire Hospital Trust) may have lead to a person to self harm as they may feel bad about themselves and therefore feel the need to punish their selves or in some cases end their lives. In places like this if self harming was discovered in a patient nothing would have been done to help them as the abusers would have seen it as a cry for help which could lead them to getting caught in the acts they had committed.In conclusion this presentation shows that abuse happens in lots of people's daily life, whether they are in a care hom e or in home or workplace and that in some cases it doesn't get found out about or nothing is done about it. It is important that abusers get caught and prosecuted and that the victims get the help they need. It is also important to out about things that a person may have seen or noticed in another. Places such as the ones mentioned in the presentation were involved in most of the types of abuse discussed and nothing was done about it until it was captured on film.

14th MANCO Linear Programming Approach for Irrigation Scheduling – A case Study H. MD. AZAMATHULLA, Senior Lecturer, River Engineering and Urban Drainage Research Centre (REDAC), Universiti Sains Malaysia, Engineering Campus, 14300 Nibong Tebal, Pulau Pinang, Malaysia; email: [email  protected] usm. my, [email  protected] com (author for correspondence) AMINUDDIN AB GHANI, Professor, REDAC, Universiti Sains Malaysia, email: [email  protected] usm. my NOR AZAZI ZAKARIA, Professor, REDAC, Universiti Sains Malaysia, email: [email  protected] usm. my CHANG CHUN KIAT, Science Officer, REDAC, Universiti Sains Malaysia, email: [email  protected] sm. my Abstract There is an increasing awareness among irrigation planners and engineers to design and operate reservoir systems for maximum efficiency to maximize their benefits. Accordingly, significant work has been done on reservoir operation for known total irrigation demand and on the optimal allocation of water available to c rops at the farm level. Very few studies have been conducted to derive optimal reservoir operation policies integrating the reservoir operation with the on-farm utilisation of water by the various crops.This present paper deals with the development of model — Linear Programming (LP) — to be applied to real-time reservoir operation in an existing Chiller reservoir system in Madhya Pradesh, India. Keywords: Cropping pattern, Water resource management, Irrigation management, Optimization 1. Introduction In most developing countries, a huge share of the limited budget goes to creating facilities for irrigation. Construction of reservoirs requires very high investment and also causes socioeconomic and environmental issues.Water in the reservoir has multiple claimants and needs to be optimally utilized to generate maximum benefits through proper operation, which must remain consistent despite uncertain future inflows and demands. According to the World Commission on Dams, ma ny large storage projects worldwide are failing to produce the anticipated benefits (Labadie, 2004). Similarly, small storage projects made for local areas in developing countries, like India, are also failing to meet expectations.The main cause identified at various levels of discussion, as reported by Labadie (2004), is inadequate consideration of the more mundane operation and maintenance issues once the project is completed. For existing reservoirs, optimum operation is critical, since all the expected benefits are based on timely water releases to meet the stipulated demand. Real-time operation of a reservoir requires making relatively quick decisions regarding releases based on short-term information. Decisions are dependant on the storage in the reservoir and information available in the form of forecast hydrologic and meteorological parameters.This is especially important during floods and power generation, where the system has to respond to changes very quickly and may need to adapt rapidly (Mohan et al. 1991). For reservoir systems operated for irrigation scheduling, real-time operation is not very common because of longer decision steps. Traditionally, the reservoirs meant for irrigation purposes are operated on heuristics and certain rules derived from previous experiences. This defies the concept of water-management; much of the water is lost, which in turn leads to loss of revenue.In the early 1960s, mathematical programming techniques became popular for reservoir planning and operation; pertinent literature is available. An excellent review of the topic is given by Yeh (1985), followed by Labadie (2004) and Wurbs (1993). Along with simulation studies, Linear Programming (LP), Dynamic Programming (DP) and Non Linear Programming (NLP) are the most popular modelling techniques. A comparative study on the applicability and computational difficulties of these models is presented by Mujumdar and Narulkar (1993).Many of the aforementioned techniques ha ve been implemented in realistic scenarios, and many reservoir systems worldwide are operated based on the decision rules generated from these techniques. However, there exists a gap between theory and practice, and full implementation has not been achieved yet (Labadie, 2004). 1 14 & 15 February 2009 Kuching, Sarawak The basic difficulty a reservoir manager faces is to take a real-time optimum decision regarding releases according to the future demand and inflow. This leads to the problem of optimization of the stochastic domain.Two approaches of stochastic optimization are practised: i) Explicit Stochastic Optimization (ESO), which works on probabilistic descriptors of random inputs directly and ii) Implicit Stochastic Optimization (ISO), which is based on historical, generated or forecasted values of the inputs through the use of Time Series Analysis or other Probabilistic approaches. The ESO approach has computational difficulties; ISO methods are simple, but require an addition al forecasting model for real time operation. In the case of irrigation reservoirs, decision making at the reservoir level depends upon the water demand arising at the field level.In order to operate the reservoir in the best possible way, it becomes imperative to understand the processes occurring in the crop-soil-water-atmosphere system. This helps not only in the estimation of accurate demands, but also ensures optimum utilisation of water. If the processes at the field level are also modelled properly and integrated with the reservoir level model, the goal of water management can be achieved in the best possible way. Dudley et al. (1971) pioneered the integration of the systems in the determination of optimal irrigation timing under limited water supply using a Stochastic DP model.Dudley and his associates then improved the model (Dudley and Burt, 1973; Dudley, 1988; Dudley and Musgrave, 1993). Vedula and Mujumdar (1992, 1993) and Vedula and Nagesh Kumar (1996) have also contrib uted to this area. Their approach was to derive a steady state reservoir operation policy while maximizing the annual crop yield. DP-SDP and LP-SDP were used in the modelling. However, for real-time reservoir operation, Vedula and Nagesh Kumar (1996) stressed the need to forecast inflows and rainfall in the current season to implement the steady state operation policy.As a result, the ESO model has to be supplemented with an ISO model to get a policy for the current period. As an extension to the work of Vedula and Mujumdar (1992), a significant contribution to the real-time reservoir approach was presented by Mujumdar and Ramesh (1997). They addressed the issue of short term real-time reservoir operation by forecasting the inflow for the current period, a crop production state variable and a soil moisture state variable. Their work was based on SDP, but had all the limitations of SDP regarding the curse of dimensionality.Against this background, a model for the derivation of real-t ime optimal operating policy for a reservoir under a multiple crop scenario is proposed in the present study. The primary issue is that the reservoir gets inflows during the wet season (monsoon season) and is operated for irrigation in the dry season (non-monsoon season). The reservoir storage and the soil moisture level are considered to be the principal state variables, and the irrigation depths are the decision variables.An optimal allocation model is embedded in the integrated model to evaluate the irrigation water depth supplied to different crops whenever a competition for water exists amongst various crops. The model also serves as an irrigation-scheduling model because it specifies the amount of irrigation for any given fortnight. The impact on crop yield due to water deficits and the effect of soil moisture dynamics on crop water requirements are taken into account. Moreover, a root growth model is adopted to consider the effects of varying root depths on moisture transfer. The only stochastic element in the season is the evapotranspiration. The handling of stochasticity has been accomplished through dependability based forecasting in an ISO model. The rest of the variables, such as soil moisture status and the reservoir storage status, at the beginning of any period are considered to be state variables. The basic formulation is based on a LP model and is later transformed into a GA framework. 2. The Model Formulation and Concept The real-time operation model proposed in the present study integrates the reservoir level and a field level decision (Figure 3).It considers the soil-moisture status and the reservoir storage as the state variables and the applied irrigation depths as decision variables. The formulation is based on the conceptual model for soil moisture accounting and the reservoir storage continuity relationships. A major emphasis is laid on maintaining soil moisture in a state such that the evapotranspiration from the crops takes place at a rate that achieves better results in the form of increased yields from the crops. To assess the timing of irrigation water application, the soil moisture status of the crop is an important parameter.Whenever the soil moisture status approaches a critical limit, irrigation is applied. Thus, the soil moisture status is monitored either by physical measurement or through soil moisture models. Soil moisture models are more popular since they do not require a lot of instrumentation to be installed in the field. Soil moisture models can be formulated either by a physical approach (Fedders et al. , 1978) or a conceptual approach (Rao, 1987). The conceptual approach has been used by Rao et al. (1988), Rao et al. (1990) and 2 14th MANCO Hajilal et al. (1998) for the problem of irrigation scheduling.Vedula and Mujumdar (1992) utilised the conceptual model in their study. The same concept is adopted in the present study. Figure 3 Flow chart of real-time operation of reservoir 3 14 & 15 Februa ry 2009 Kuching, Sarawak 3. The Conceptual Model In the conceptual model for the Crop-Soil-Water-Atmosphere (CSWA) system, the basic assumption is that the soil acts as a reservoir, the main inputs to the reservoir are rainfall irrigation, and the main outputs are evapotranspiration, percolation and drainage. The extent of the reservoir is considered to be up to the effective root zone at the particular time.The soil water reservoir is governed by a continuity equation: ? ik +1 ED ik +1 ? ? ik ED ik ? IRR ik + AET i k = RF k (1) The conceptual model stated by Eq. 1 is used to compute the irrigation to be applied for the LP model with area as a decision variable. The following parameters are important for the conceptual model. Figure 1 shows the sketch for the conceptual reservoir. In the context of the conceptual model two parameters are important: IRRk RFk AETk EDk ?k Figure 1 Conceptual model Variation of Evapotranspiration with the Available Soil Moisture Evapotranspiration as a function of the available soil moisture is expressed as: kAETi k = PETi k if aai ? Zww (2) or AETi k = k aai PETi k Zww where AETi k (3) is the actual evapotranspiration that has occurred from crop i in fortnight k (mm), PETi k is the potential evapotranspiration in a particular geographical location (mm), Zww is the critical available moisture limit (mm/cm) = (Zf? Zw) d, Zf is the field capacity for the soil (mm/cm), Zw is the permanent wilting k point for the soil (mm/cm), d is the depletion factor and assumed to be 0. 5 in the present study, and a ai is the average available soil moisture over a fortnight (mm/cm). The average available soil moisture over a fortnight is given by ik + aik +1 a= 2. 0 k ai where otherwise aik = ? ik ? Zw if aik < Zww aik = Zww k +1 A similar expression can be used for ai . 4 14th MANCO Root Zone Depth Growth The root depth data in relation to the time stages are prepared according to the Linear Root Growth Model (adopted by Narulkar, 1995). The model assumes that maximum root depth is achieved at the start of the yield formation stage. It remains at the maximum depth until the maturity stage. A minimum depth of 15 cm is considered in the first fortnight to account for the conditions of bare soil and an area with sparse crops.The root depth model is shown in Figure 2. Life span of group Growth stages of group V F G Root Depth Max. Depth Figure 2 Root Depth growth model Relative Yield Ratio The yield of a crop is affected by water deficits and the rate of evapotranspiration. The rate of evapotranspiration tends to decrease depending on the available moisture content. There are many methods to model the phenomenon. However, the model used in the present study is the most commonly-adopted model. The relative yields are computed on the basis of the expression given by Doorenbos and Kassam (1979) YaiAETi k ? k? = 1 ? Ky ? 1 ? ? PET k ? ? Ymi i? ? (4) Equation (4) gives a yield ratio for a single period only. However, the aggregate ef fect of moisture deficits over all fortnights of crop growth is also evaluated. The final yield ratios computed for the crop during various time periods of a season is computed by a multiplicative model (Rao et al. , 1990). The determination of the yield ratio is very important since they reflect the operation policy for an irrigation system. The expression is given by ? AETi k Yai ncr ? = ? ?1 ? Ky k ? 1 ? ? PET k ? Ymi i =1 ? i ? (5)Water Requirements of the Crops The model derived for an optimal crop pattern uses predetermined irrigation demands. On the basis of this, the optimisation model selects an appropriate area for an individual crop. The irrigation demands are determined using the conceptual model stated in Eq. 1. The irrigation requirements may be calculated by substituting a value of critical soil moisture content instead of soil moisture in either of the fortnights k and k+1 and replacing the values of actual evapotranspiration by potential evapotranspiration and re arranging the terms of Eq. : ( ) IRRik = ? cr EDik +1 ? EDik + PETi k (6) 5 14 & 15 February 2009 Kuching, Sarawak where ? cr is the critical soil moisture content below which the actual evapotranspiration may fall below the potential rate. 4. Integrated LP Formulation In the objective function, the weighted sum of all the actual evapotranspiration values is maximised. The weights are assigned according to the yield response factors for individual crops in individual periods. The objective is to maximise the actual evpotranspiration rate to minimise the deficits in the yields.The available soil moisture in any time period in the objective function is indirectly maximised: ncr np ? a k + aik +1 ? Ky k MaxZ = ? ? ? i ? 2. 0 ? Zww i =1 k =1 ? (7) subject to the following constraints: 1. Soil moisture continuity ? aik + aik +1 ? PET = RF k ? 2. 0 ? Zww ? ? ik +1 EDik +1 ? ? ik EDik ? IRRik + ?

IRRik * AREAik = ? ID ? Ao RE k Eff (Maximum Reservoir Capacity M m3) (12) (13) Crop Simulation ModelThe optimisation model presented above yields some irrigation depth values that are based on forecasted values for the reference evapotranspiration. This reference evapotranspiration, in turn, is based on a dependability model. However, the actual evapotranspiration value differs from these values, and thus, before going into the next fortnight, the soil moisture status must be updated with the applied irrigation and actual climatic factors. The formulation for crop simulation is as follows: First compute the final soil moisture with the following relation ? ik = (? ik +1 EDik +1 + IRRik ?Fkcik APET k + ARF k ) / EDik If (14) ? ik +1 < 3. 1 ?k ?

Stochastic Analysis of Evapotranspiration It was previously stated that the data regarding the climatic factors is uncertain in nature and the determination of these factors beforehand is impossible. However, there is a general trend to assume the expected values for these factors and carry out the operation. The concept does not give a clear picture of the actual scenario and the appropriate weights for the individual growth stage of the crops are not assigned. The present study proposes a different method of forecasting the expected values for the climatic factors.The method of analysis starts with the co mputations of dependability values of reference evapotranspiration factors from the available data. The dependability of realisation of any stochastic variable is defined as the probability of equalling or exceeding that variable with a particular value. Mathematically, P(x ? X ) (18) where P (. ) is the probability and x is the variable under consideration and X is a stipulated value of the variable. A traditional method of estimation of the dependability value is the use of standard frequency formulae (e. . Wiebull’s formula or Hazen’s formula). In the present study, a detailed probability analysis for the data is performed. The data is fitted to a standard probability distribution and the best fitting distribution is tested through the Kolmogorov Smirnov Test (Haan, 1977). Once the values corresponding to different dependabilities are evaluated, dependability values for reference evapotranspiration are assumed to be different in different growth stages. The analysis is performed on the basis of the yield response factor.A high yield response factor signifies greater sensitivity towards the deficits, and thus, a higher level of dependability is assumed for the evapotranspiration data and a lower level of dependability is assumed for the rainfall data. This will ensure a higher value of irrigation required for the crop in the sensitive period. As a result, the crop will be safeguarded against any poor moisture content conditions. 7. LP Model Formulation for Optimal Cropping Pattern At the start of each dry season, depending on the storage volume in the reservoir, the crop pattern must be determined.To evaluate the crop pattern, another LP model is used. In this model, irrigation depths are calculated from Eq. (6). The formulation is as follows: The objective function is MaxZ = C1 X1+ C2 X2+ C3 X3 (19) which is subject to the following constraints: 1. Total available area X1+X2+X3? A (20) where X1, X2, and X3 are the decision variables related to the area of individual crops;C1, C2, and C3 are the cost coefficient for each crop in Indian Rupees (1 US $ = 50 INR); and A is the maximum area available for irrigation. 2.Area of each individual crop: 7 14 & 15 February 2009 Kuching, Sarawak The area under each crop is required to be constrained; thus, there are lower and upper bounds on the area under each crop. The lower bounds indicate the minimum area that can be allocated to a crop, while the upper bound indicates the maximum. In the present study, the lower bounds were defined for all the crops except cash crops, while the upper bounds were defined considering the present cropping pattern. The constraints can be expressed as Li? Xi? Mi (21) here Li corresponds to the lower bound of the area for the ith crop and Mi corresponds to the upper bound on the area of the ith crop. 8. Model Application The developed models were applied to the Chiller reservoir system in Madhya Pradesh, India (Latitude 23o23’ N and Longitude 7 6o18’ E). In the central part of India, many reservoir projects have been constructed for irrigation, but no irrigation is available from these reservoirs during the monsoon period (from June to September). The area receives about 90 to 95 % of its rainfall during the Monsoon season. The rainfall then becomes runoff to the reservoirs.These reservoirs are designed to contain the runoff in the monsoon season, but there is no runoff during non-monsoon months. The present formulations are specially suited for these types of reservoirs. Non-monsoon rainfall is rare and provides little runoff. A systematic data base was prepared for the various physical features of the reservoirs, including the meteorological and hydrological data such as evapotransiration, details of crops in the command area, details of net returns from individual crops and soil properties collected from the College of Agriculture, Indore, India. . Results and Discussion Optimum Crop Pattern A separate computer p rogram was run before the real time operation program to determine the optimum crop pattern for all possible storage values. The results of the optimum crop pattern are stated in Table 1. The results indicate that from a storage level of 31. 10 M m3 to a storage level of 26. 06 M m3, the cropping pattern is same as the one that has been adopted in the project formulation. However, below a storage level of 26. 06 M m3, the crop pattern changes suddenly, and wheat (ordinary) is not recommended by the model.The area of wheat (hybrid) also gets reduced when the rainfall storage is below this level. However, the area for Gram is full, up to a storage level of 15. 83 M m3. The change in cropping pattern indicates that efficient water usage is maintained.

The model also yields the values of irrigation to be applied to individual crops in the fields. In the wake of deficient water supplies, the model distributes the available water over the time for different crops optimally. The sample results of the present model are stated in Table 2.The available moisture to the crops is not affected, and generally the soil remains at the upper limit of the available soil-moisture. This 8 14th MANCO is because the crop pattern is predicted according to the availability of the storage in the reservoir. The results are indicative of successful application of the real-time operation strategy proposed in the present work.

Furthermore, the models ensure an optimum reservoir release over different time periods.In addition, they also ensure optimum allocation of the available water over the different crops in the fields. While allocating the water to different crops in the fields, the model takes into account the critical growth stages of the crops and allocate s sufficient water to each crop to safeguard it against any ill effects of water deficits. The optimum crop pattern model used in the study will only allow productive irrigation, so the amount of wasted water is reduced.

Adaption vs. Adaptation

Adaption vs. Adaptation Adaption vs. Adaptation Adaption vs. Adaptation By Maeve Maddox A reader in the UK who grew up hearing the word adaption used in reference to radio and television programs based on books wonders, Where did adaptation come from, since there is no verb adaptate? The earliest OED documentation of the verb adapt is dated 1531. The noun adaptation comes along in 1597, 18 years earlier than adaption (1615). English has no verb â€Å"adaptate,† but the past participle stem of Latin adaptare (to fit, to adapt) is adaptat-. Adaptation came into English from French, with the extra syllable already in place. Adaption looks like a homegrown nominalization of the verb adapt. The Google Ngram Viewer, which tracks the incidence of words in printed sources from 1800 to 2000, shows adaption running a distant second to adaptation during the entire period. The OED has a brief entry for adaption, prefaced by the notation â€Å"Now nonstandard.† Clearly, adaptation is the standard form of the word meaning, â€Å"an altered or amended version of a text, musical composition, etc., especially one adapted for filming, broadcasting, or production on the stage from a novel or similar literary source.† But although adaptation is the preferred spelling, adaption is in use among English speakers in Canada, Australia, the UK, and the US: The Snow Queen: A Pop-Up Adaption of a Classic Fairytale  Hardcover  Ã¢â‚¬â€œPublication date: 2013. Movie Adaption > Popular Movie Adaption Books –categories on Goodreads Why book-to-film adaption soundtracks need to fit with the original book –headline, The Guardian Lake Bell to Direct Film Adaption of  The Emperor’s Children –headline, Time.com The Broadway musical  West Side Story  is an adaption of  Romeo and Juliet.  Ã¢â‚¬â€œarticle, The Globe and Mail (Canada) On a page at the BBC News site, adaption occurs in a header, but adaptation is used in the text below it. Bottom line: Some writers in the English-speaking world continue to use adaption as an alternative spelling of adaptation, but adaptation is the preferred standard form.

The Winged Victory of Samothrace, aka Nike Essay

The Winged Victory of Samothrace, aka Nike - Essay Example â€Å"The Winged Victory of Samothraceâ€Å", or the Nike, represents the aesthetics of the ancients while engaging the artistic sensibilities of the modern man. One of the ways that the statue, The Winged Victory of Samothrace, reflects the aesthetics of the culture from which it came is through the androgyny of the figure. While the figure is decidedly female, it has a thick body and firm stance that is often associated with androgynous figural sculpture of Ancient Greece. The figure is actively engaged, its dynamic stance showing action and intensity as it also reflects victory through its sense of triumph. The pose is captured, as if the figure that it represents as stopped still in a moment, its thrust forward coming to an abrupt, but meaningful stop as it expresses the theme of triumph. The sculpture has an emotional context that evokes passions within the viewer. Even without its full form, it is a powerful piece of work, its smallish, but well constructed wings suggesting t he heights of victory as it is coupled with the dynamism. The Greeks were partially to the flowing fabrics, the beauty of the details creating the feminine side of the androgynous ideal. Often the faces were the primary defining element to the androgyny, but because the face is missing, the masculine is someone less apparent in the duality of gender. Macleod writes â€Å"If the androgynous male youth is characterized by openness, the moment of perfect beauty in the realm of female deities is not that of a free-floating adolescence but rather the static self-sufficiency, the containment of mature Juno† (51). The female tilt of the androgynous balance is found to have beauty when the determination of self-sufficiency can be observed in the stance of the figure. Even though the face is not available to provide deeper clues to context, the emotions of the piece and the way in which the duality is expressed is clearly available to the viewer through the details of the expressive n ature of the body. The work does not near appear the way that it was seen by the public that it was intended to engage. The piece is fractured, the arms and the head missing, although there is some evidence that the Romans have duplicated the head on some of their work as they copied the Greeks. The work was painted, originally, an aspect that a modern audience would more than likely find garish.
