The Effect of Methamphetamine-induced Neurotoxicity on Crime Rates free essay sample

Methamphetamine destroys the body’s neurological processes, leading to impulsive behavior and ultimately breaking the law. Over 56% of state prisoners committed their crimes while under the influence of an illicit substance (Mumola 1). Out of all crimes committed while under the influence of a drug in 2004, 64% of them were petty theft and property offenses, such as burglary or larceny. The use of methamphetamines causes neurotoxic effects on serotonin neurons, resulting in anxiety and mood swings which could spur an individual into committing non-aggressive crimes. Methamphetamines also behave as neurotoxins to dopamine, resulting in a deficit of the neurotransmitter (Kish 1679). Depletion of serotonin and dopamine in the brain cause symptoms of depression, obsessive compulsive behavior (such as the actions of the stereotypical â€Å"tweaker†) and anxiety (â€Å"Methamphetamine in the Brain†). After long term use, dopamine and serotonin-induced depress ion can lead the addict to commit acts of thievery in order to purchase more methamphetamines, which become the body’s main neurotransmitter release stimulant. We will write a custom essay sample on The Effect of Methamphetamine-induced Neurotoxicity on Crime Rates or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Short term use of methamphetamines promotes paranoia, sleeplessness, depression and anxiety (â€Å"Short Term Use†). Further use of the substance causes these symptoms to become more severe, resulting in depression and a loss of functional social behavior (â€Å"Long Term Use†). Liz Sonneborn’s book, Frequently Asked Questions about Shoplifting and Theft, notes how many chronic shoplifters suffer from imbalances in serotonin levels, which cause depression and obsessive behaviors (31). Methamphetamines are psychomotor stimulants that flood neurotransmitter-receptors, tricking the mind into releasing a magnified high that, under normal circumstances, would only be experienced at a slight degree (â€Å"Methamphetamine in the Brain†). However, repeated administration of methamphetamines to lab rats shows that after long term use, methamphetamines significantly reduce the amount of serotonin and dopamine content and uptake in the body by acting as a neurotoxins (Cass 8132). Once methamphetamines become neurotoxins, the resulting depletion of serotonin and dopamine in the body cause severe depression when not high, as dopamine is responsible for the experiencing of pleasure and pain (Erickson). Methamphetamines also act as receptor desensitizers, actually reducing the number of neurotransmitter receptors and causing the addict to build a tolerance to the drug. Therefore, depression is stimulated because the individual experiences limited enjoyment when not on methamphetamines, and a progressive decrease of enjoyment while high. Depression further spurs theft (Khimm). An article by The Washington Post states the National Bureau of Economic Research discovered that non-violent theft is the only crime that can statistically be attributed to depression among adolescents and young adults. Depression of this level could be attributed to methamphetamine usage, and a study in 2004 showed that out of the 53% of state prisoners who regularly used drugs, 14.9% used methamphetamines, 36% claimed they continued usage despite emotional problems, such as depression, and 34% claimed to have an increase in tolerance to the illicit substance (Mumola 2). In the case of methamphetamines, this signifies that over a third of users continue using methamphetamines despite having severe depression. Furthermore, the 34% who showed an increase in tolerance would also be using higher dosages of meth, further shutting down their neurotransmitter receptors. Depression aside, dramatic decreases in serotonin levels have an inve rse relationship with impulsive behavior (Raine 96). Impulsivity has a significant effect on property crime (Zimmerman 69-70). In Gregory Zimmerman’s book, statistics show that an individual who exhibits normal impulsivity has a probability of 11% of engaging in property crime, such as burglary. However, when impulsivity rises by one standard deviation, the probability of engaging in a property crime increases from approximately 11% to 23%. One of the defining roles of serotonin is to mediate behavioral inhibition (Dalley 41). The decline in serotonin concentration and uptake causes individuals to less effectively correlate rewarded and punished responses. This means that whereas one individual may associate shoplifting with being fined or sued, an individual with decreased serotonin levels, due to methamphetamines, will identify the rewards of shoplifting and the punishments of being caught as two unrelated events. Along with causing the deterioration of users, methamphetamines also have an undeniable negative effect on the lives of others (Mumola 1). Methamphetamine causes the depletion of chemicals that naturally make people feel happy and replace it with feelings of depression and impulsive disorders (â€Å"Short Term Disorders†). The general lack of happiness caused by the use of meth results in higher crime rates, and although the crimes are generally nonviolent, they still detract from the safety of people’s homes and their rights to their property (Mumola 1).

Hydrogen Technology Research essays

Hydrogen Technology Research essays With the current economy, world situation, and predicted environmental future of the fossil fuel age a change needs to be made. Hydrogen power is a very popular solution to the fossil fuel problem. There are however many group involved in this situation that need to be taken into account. These groups include engineers, politicians, and the common person. Engineers need to take into account several factors in their acceptance of hydrogen power. First off, the textbook says that hydrogen power producers are high in prices as compared to the cheap fossil fuels available today (Miller 409). This is true, but other factors need to be taken into consideration. Including that as the demand for hydrogen utilizing machines increases, the supply will increase, and the price for the machines will go down. So if the price is incurred now, it will decrease in the future. Another critical problem that engineers are primarily facing now is storage. There are several possibilities, but all have their downfalls. The biggest problem facing hydrogen storage is that, Hydrogen gas is not an energy-dense fuel (Princeton). This basically means that a bunch of hydrogen will yield a little bit of energy. So large volumes of hydrogen need to be utilized in order to be effective. Hydrogen, however, is not very easy to store because of its extremely low evapo rating energy level. This means that liquid hydrogen would take up tons of energy to be kept in liquid form, which is very inefficient. Technology is currently being tested that would store hydrogen in other compounds, from which hydrogen can be easily extracted. This however could result in dangerous compounds being produced, and the compounds might also be too expensive to be used on a mass scale. One more problem that engineers face is that hydrogen is not found alone in nature. So it must be extracted from a compound. The most popularly thought of way to extract hydrogen is through the el...

Critique of Vita Wallaces Give Children the Vote Essay

Critique of Vita Wallaces Give Children the Vote - Essay Example In her article, she presents her views on the significance of educating children and giving every child the right to vote. Wallace says that in passing the law against child labor and provision for compulsory schooling, the involved, which she refers to as well-meaning people aimed at protecting every child from any form of exploitation. She believes that the decision about schooling I personal. According to her, no punishment should be given in case children choose not to attend school. Rather, she asserts that at whatever age suitable for children to vote, the right should be given. She says, â€Å"What I suggest is that children be allowed to grow into their own right to vote at whatever rate suits them individually†. The word individually helps eliminate the aspect of generalization. According to her, age limit would hinder capable children from voting. It is from this assertion that Wallace believes that children should have the right to vote. The common believe that if g iven the chance to vote children will vote in favor of their parents, in effect giving more votes to the parents should, according to Wallace, not be the case.Although many of the readers of this article consider Wallace argument thoughtful, I disagree with her point of view. In the entire essay, she presents her opinion. However, the major claim of this assertion could appear as fact or a judgment. This shows how he overlooks the Toulmin’s theory of argument. As an activist, she uses an interesting approach, which convinces many readers.... In the entire essay, she presents her opinion. However, the major claim of this assertion could appear as fact or a judgment (Cooper 5). This shows how he overlooks the Toulmin’s theory of argument (Cooper 3). As an activist, she uses an interesting approach, which convinces many readers. Despite her powerful approach, I consider her unsuccessful. Her major claim, giving children the vote, is an aspect cringed about by many children. However, her presentation is form of defense for herself and other kinds. From her view, she was discriminated since she was home schooled, a fact that brings her ideas that children should not be force to attend school, neither should they be punished for choosing not to. In her article she says, â€Å"Learning about discriminatory laws preventing high school dropouts from getting their driver’s licenses†¦ (316)† this shows how she how she discusses â€Å"Discriminatory laws†. This statement leads to a minor claim when s he says, â€Å"Punished for exercising one of the few legal decisions they now have (316)†. This is a claim for own defense. Further, it convinces the reader to belief that there is unjust treatment to young dropouts. The fact that she overlooks the personal responsibility involved in dropping out of school and the individual’s self-worth make the claim weak. She successfully uses warrant to convince readers as defined by Cooper (4). Though her emotional pleas are worth listening to, minimal facts in her case and lack of evidence make her argument unpersuasive. Further still, her writing is jumpy and the thoughts are scattered hence the entire case is hard to believe. For instance, the statistics she provides for eligible adult voters is the only strongest evidence she can rely on. From her statistics out of the

Cf child - Essay Example All identified effects of the exercise were positive induced emotional and physical status as well as the children’s self worth. The children’s willingness to engage in the practice was however low and parents’ support for the exercise program was poor. While outpatient exercise offers a solution to cystic fibrosis among children, its implementation has not been embraced and this could account for the persistent incidence rates. Validity and reliability of the study, based on the empirical approach over a long period, means that exercise is effective for managing cystic fibrosis, and should therefore be prescribed to the patients (Gulmans, De Meer, Brackel, Faber, Berger and Helders 1999, p. 39-45). Another study on effects of physical exercise on cystic fibrosis condition supports significance of exercise as a management strategy. The study by Zach, Oberwaldener and Hausler that exposed cystic fibrosis victims to physical exercise, without any alternative management strategy, identifies both short term and long term effectiveness of physical exercise. Improvement in forced expiration, as the results showed, supports effectiveness of the exercise in resolving the respiratory inefficiency among the cystic fibrosis patients. The study’s results identify effectiveness of exercise as a management strategy because of improved airflow and muscle functionality. Even though the patients did not report improvements in their lung capacities, the positive changes that the treatment induced mean that exercise is an effective strategy. Exercise if further a natural approach and therefore offers better safety, because of freedom from potential adverse effects of chemicals in industria l medications that have been used to manage cystic fibrosis. The empirical results can therefore be used to support application of exercise as a safe and effective alternative to management of cystic fibrosis (Zach, Oberwaldener and Hausler 1982, p. 587-

In effect, the documentary reveals Mann’s personality to the viewer, which makes the viewer understand her photography work. The documentary provides the viewer with an understanding of the factors behind the personal nature of Mann’s photographs. In this case, her preoccupation and strong relationship with her family are instrumental in Mann’s photography since some of work may appear provocative, which underlines her open-mindedness. As earlier indicated, Mann uses old equipment in the contemporary technological era. In this regard, her large format camera requires exposure times of a number of minutes before use. In effect, this shows her patience and calmness, which provides her with the impulse to capture beautiful photographs. In addition, Mann produces her photos in a fragile and old process that makes her lose some photographs in the process. In this case, this is a depiction of a strong sense of idiosyncrasy, which implies her remarkable willingness to pursue unconventional ideas. In conclusion, the documentary depicts Mann as a remarkable individual intent on pursuing her goals. Although she uses old procedures and equipment, Mann’s work is humbling to photographers and all artists since she exploits the flaws of old procedures to produce unintended patterns that enhance her concept and aesthetic values in

Health Care Access for Maori and non-Maori

Health Care Access for Maori and non-Maori Health care access and opportunities for Maori and non-Maori   Assessment 1 individual INTRODUCTION It can be said that; ‘Of all form of inequality, inequalities in health care the most inhuman of all’. This assessment is concerned with social, economic, political and historical factors which contributed to health status of Maori and non-Maori. Inequalities and disparities in health status comes are considerable. So there is a dramatic difference between Maori and non-Maori health status due to many reasons such as poor nutrition, lowest income, inappropriate education system, culture, language, loss of lands, unhygienic foods and many more. The recommendation in this assignment focus on different factors related to health of Maori and non-Maori people. In which to identify the biggest causes the poor health status and better understand the casual path linking of social, political, economic and historical factors. There is wide disparities in health exist among people in New Zealand. Treaty of Waitangi The treaty established a British governor of New Zealand, which recognised Maori ownership of their lands and other properties. The treaty of Waitangi is first signed in 6th February 1840 by British crown. Around 530-540 chiefs, at least 13 of them women, signed the treaty of Waitangi. The English and Maori version of treaty different, so there is no consensus .the Maori believed they ceded to the crown a right of governance for protection without giving up their authority to manage their own affair. There is following views which contributed to inequalities and disparities in Maori and non Maori health status; Social Review Social status is based on occupation, education and life style of Maori and non-Maori people which is key determinant of health. There is a combination of materials like poverty in which includes poor housing, poor nutrition and stress caused by low social health status results in health inequalities. As a social factor, lifestyle is most dominant cause of inequality because the Maori has different lifestyle than non-Maori. In which cancer is single biggest cause of death in Maori due to taking of smoking and exposure to second hand smoke. Apart from this, it is noticed that the Maori women were twice as likely to smoke as women of non-Maori population. so the excessive smoking may lead to lung and breast cancer in Maori people. Moreover other associated factors are excessive alcohol consumption and more exposure to sun which contribute to bad health status. In addition nutritional habits also put great impact on health status of Maori and non-Maori. The Maori has poor nutritional ta ke and also more obese than non-Maori. So obesity is very dangerous for health that may lead many other health problems and dangerous diseases which may even lead to death. Furthermore heart diseases and genetic components are major factors that associated their lifestyle in which Maori people has low physical activity and poor nutrition intake influence the health. In addition to it, the use of mental health services served in 2002 was more in Maori rather than other islanders. Maori have high admission rate to mental hospitals and the diagnose and aetiology behind the mental disorder was related to their lifestyle like alcohol and drug consumption because drugs are directly affecting on brain nerves and a person becomes mentally week which can make is mind unstable and he is a way of any understanding due to the effect of drugs. Moreover unsafe sexual habits, gambling and participate in dangerous activity are also a case of bad health status on Maori people. In brief social conditions are particularly important in determining health of people because when a social environment is supportive then great influence on health. At last it can be said that poor nutrition, bad lifestyle, disruption, urbanisation, inappropriate education and poor nutrition intake lead to inequalities and disparities between Maori and non-Maori population. Economic Review There are number of survey has been done to recognise the economic factor that contribute to the health status of Maori and non-Maori. The economic level is very different of Maori and non-Maori people that may affect the health of both populations. It has been showed that non Maori men have more income than Maori. The low income people have not sufficient money for the treatment of disease because in new island income inequalities have been increased in late 1980 and 1990. This standard of living is some degree of hardship and fall in unemployment. Beside this loss of shelter, food and land are important determinant that may lead bad health effect on Maori people. The Maori population has no access of telephone, not receiving a man texting benefits, low income, illiteracy, overcrowded housing and even not living in their own home. So in this way Maori health status is very low as compared to non-Maori. It is also suggested that inequalities in income also contribute in death rates. Furthermore, decline of Maori population in 18th and 19thcentury of colonisation. It is also believe that impact of colonisation in such a way like loss of land, houses, food, culture and language may lead to bad status on health 0of Maori people. Furthermore, racial factor is also contributed in inequalities. It can be understood by low qualification rate of Maori people because western education system was not appropriate for Maori. Maori and the reason behind this was other cause is unemployment in which seen that Maori have high rate of unemployment than non-Maori were lived in rural and natural places. Last but not the least cause under economic factor is poor health delivery care service to Maori people. So at the end it can be include that colonisation, loss of land, literacy, and overcrowded housing leaded negative effect on Maori health status. Historical view In view of history the Maori people lived in rural areas or small town. The ancestor of Maori was illiterate and had no value of education. So in this way their children have also not went to school and unaware about value and need of education. The rate of school completion in 2001 was very low in Maori group (30.5%) as compared to non-Maori (52.4%).as a result of rate of unemployment was twice than European part. Apart from this, from a decades and century the Maori was very prone to many ischemic heart disease, lung cancer, liver cancer and diabetes which all diseases may be seen in hereditary form also. In addition, most of Maori was prone to physical disabilities that may put great impact on Maori health. The other reason behind inequalities of health status in Maori and non-Maori people was old education system. Before 1840s, the Maori children only learnt language, skills in fishing, mat-making, hunting, gardening, cooking and many more which only related to Maori. But after 1840s many schools were established by European missionaries and forced Maori children to attend ordinary schools. But Maori children did not reach an acceptable level of European education and consequently, Maori students leave the school early. So in this way they were illiterate and unemployed which resulted that they were not participated in health care services and self-health care that may lead to high mortality rate in Maori population than non-Maori. In addition, bad and negative perception regarding hospital was one of reason of inequalities in Maori and non-Maori. There was hospital system proven ineffective in Maori population because nonetheless, thirteen Maoris patient were died from 1849-1851 and these deaths had negative effect on Maori perception. They concluded that ‘hospitals had a bad name among Maoris, they were thought of as places where one went to die’. Political view The politics has great impact on Maori and non-Maori health during the 1990s there was broad agreement between major political parties that settlement of historical claim was appropriate, in recent years it has become the subject of heightened debate. According to have Mann (1999) in 1848 -1863 the whole land of South Island by unscrupulously purchasing land from Ngai tahu tribe’s .but consequently this leaded to invasion in Waikato and tahini tribes. In case of question about the responsibilities of central government ,more than 80% respondent thought it should be the government role to maintain the standard of living and standard of health so in this way ,it was the government responsibility’s to provide jobs and reduce the income inequalities between Maori and non-Maori during the 1990s there was broad agreement between major political parties that settlement of historical claim was appropriate ,in recent years it has become the subject of heightened debate. According to have Mann (1999) in 1848 -1863 the whole land of South Island by unscrupulously purchasing land from Ngai tahu tribe’s .but consequently this leaded to invasion in Waikato and tahini tribes. In case of question about the responsibilities of central government, more than 80% respondent thought it should be the government role to maintain the standard of living and standard of health so in this way, it was the government responsibility’s to provide jobs and reduce the income inequalities between Maori and non-Maori. Housing The structure of housing is different in Maori and non-Maori population. The Maori people lived in rural areas where all facilities in home were not reached properly. so in asthma. In 2001 air pollution from home heating was associated with almost 1100 premature deaths. so because health status is largely determined by socio economic factors the improvements are mainly influenced by housing quality. Health care access and opportunities for Maori and non-Maori The Maori journeyed to New Zealand via pacific approximately 1000 years and the first recorded accrued in 1769 at the time of James cook from Britain. There is increasing evident that Maori and non-Maori differ in term primary and secondary health care services .in which the Maori less likely to preferred to surgical care and specialist services .other one is the Maori received lower level of health care than expected level of quality hospital. The Maori obtaining necessary care only from local areas as compared to non-Maori. There is another evident from previous study which reported the barrier to assessing the diabetes among Maori and Maori got unsatisfactory care rather than non-Maori population. Moreover, the cost involved for a treatment is also a significant barrier to Maori access to health services. Rights of others and legitimacy of difference This way the Maori people has not proper ventilation and exhausted fan in house which leaded respiratory problems in Maori population. The Maori houses are cold, damp and polluted which leads many problems. The all human being in this world has their own rights according to their culture and religion. So it is important to understand the different rights of others. The first which one is absolute rights which must never be limited in any way even a state of war or emergency. Moreover the right is not to be tortured in an inhumane way. Other one is non- absolute which can be limited in certain circumstance. Under this right the all people have right to liberty can be limited include being sent to jail if commit any crime. In which non- absolute the qualified right is that to respect for private and family life, right to freedom of expression, thought, and religion. LEGITIMACY; is a popular acceptance of an authority. It is a value whereby something or someone is recognised and accepted as right and proper. In which include different people has their different rational values, customs and habits.Morover every person have their own ideas or charisma of leader. Apart from this, government institution establishes and enforces law and order in the public interest. The legitimacy of intergroup status differences has profound effects on attitude, emotions and behaviour. In 143 hospitals organization noticed the effects in two forms managerial and technical. Results shows that both the managerial and technical forms provided notable improvement in survival chances. The power relationship in healthcare; The health care providers and practitioner play a vital role in power relationship .they are the persons which provide the health care in all level of health and all category of people either poor and rich, Maori and non Maori there was a strong evidence of a dose –response relationship between Maori and non Maori and racial discrimination in health care centres. The Maori was 10 times more likely to experience multiple type of discrimination as compared to Europeans and others. These results highlight the need for racism to be considered to eliminate ethic inequalities in health care. In health care setting the nurses identifying the power relationship between the services provider and the people who use the services. the care provider must an emphasis health gains and positive health outcome because all people has different in age, gender, sexual orientation, occupation and socioeconomic status, ethnic origin or migrant experience, religious or spiritual belief, disability. The nurse accepts and sorts alongside others after undergoing a careful process ofpower relationship .the health care provider concern about quality improvement in service delivery and consumer rights. Moreover health care provider resolves any tension between the cultures of nursing and the people using the services. Beside this, accepting the legitimacy of difference and diversity in human behaviour and social structure. So at last but not least it must needed to understand that such power imbalances can be examined, negotiated and changed to provide equitable, effective, efficient and acceptable service delivery, which minimises risk to people who might otherwise be alienated from the service. Conclusion All above review has been evident for disparities and inequalities in health care between Maori and non-Maori. There is complex factor complex of factors associated with historical, social, economic, housing, and political views for access to The all above review has been evident for disparities and inequalities in health care health care that also underpinned by racism which leads ethics inequalities. Although study has reported how the uses of health care services in Maori and non Maori population at the different level and different way. So it is a combination approaches which meet the different views and cultural safety is one of the indigenous nursing approach which response to inequalities for Maori.

Are School Uniforms Beneficial or Not? Essay -- Argumentative Educati

Are School Uniforms Beneficial or Not? (â€Å"Quotes about Uniform Policy† 1). Theodore R. Mitchell, UCLA School of Education says, "I think its great news for all of us who have advocated school uniforms as a way of building community.† A pressing issue, bullying has become a big problem in many school, and to eliminate this problem, school policies should require students to wear uniforms. Many people believe that school uniforms build the community into a safer, more positive environment. School uniforms improve school academics, prevent gang violence, and assist families, who can not afford expensive clothing. Worrying more about others, rather than themselves, students pay more attention to the appearance of their peers instead of their academics. To begin, if school uniforms became apart of the school policy, students’ academics would improve phenomenally. Hanley noted that â€Å"The reason for the policy [was] to further improve ascending test scores and provide a safe, comfortable learning environment† (A1+). Clearly, school administrators wanted to improve test scores, and they figured if students dressed the same, then they would have no other choice but to focus on their school work. If the students can concentrate on their school work, then they will have high self- esteem. Furthermore, Valdez believes that school uniforms, positively, will change student academics: â€Å"†¦ [they] decrease self consciousness and increase self esteem...† (14). Reasonable and realistic, students who feel better about themselves will succeed in school rather than those who have poor self-esteem. Not only do school uniforms encourage students to have a better attitude about themselves, but they also change the environment in which students learn.... ...Print.

These AWIFS images of same country were co-registered with regard to the LISS-III dataset in UTM projection similar to LISS-III images. Similarly, the images were re-sampled at 60m spacial declaration by utilizing the nearest neighbour re-sampling method and entire 17 GCPs were collected from the LISS-III images for the intent of geo-registration. The difference between trial image ( AWIFS ) and mention image ( LISS-III ) is 1:3, which implies that, one pel of AWIFS image is equal to nine pels of LISS-III image.Methodology AdoptedIn the present survey the medium spacial declaration AWIFS informations sets are used. In order to accurately map the specific crop-wheat, we use temporal informations sets. Different datasets with changing temporal declaration were taken in order to happen out the most suited time-series ( multi-date ) image set that gives the best truth of categorization. In 2008-2009 Rabi Season- Wheat Growth Period Nov Dec Jan Feb Mar Apr ( image3 ) ( image4 ) ( image2 ) ( image5 ) ( image1 ) Suitable set ratio method Suitable fuzzy based supervised categorization for pull outing individual category of involvement Accuracy appraisal ( Using soft mention informations ) Figure: Methodology adopted The enhanced images were available for our survey. The images are, in general, enhanced by pre-processing like geometric and atmospheric corrections. The images are geo-referenced utilizing land control points and so registered. This work is done utilizing commercially available ERDAS package tool. Training sites for wheat were identified in the digital LISS III and AWIFS image with the aid of land control point inside informations provided and the visually interpreted FCC images. Band ratio techniques were employed to extinguish the consequence of incline and facet and the difference of light. Normalized Difference Vegetation Index ( NDVI ) , MIN/MAX and Transformed Vegetation Index ( TVI ) were taken for all the images from AWIFS and LISS-III. This was done utilizing the SMIC package tool. The fuzzy set theory based sub-pixel categorization technique was used for farther categorization utilizing temporal informations. The samples of wheat were taken from both AWIFS and LISS-III time-series images severally. SMIC package tool at IIRS was used. Sample was taken in the mode that, one image was in the spectator while, other temporal images were arranged as the chink on spectator pick the value of all the images at that peculiar pel ( category ) . The fuzzy based classifier was used for categorization. The categorization was done by Possibilistic c-Means classifier attack. The end product was a individual classified fractional image, from which we analyzed the individual category ( wheat harvest ) . Further, the truth appraisal of all the classified AWIFS fractional images was taken with regard to LISS-III image. FERM ( Fuzzy Error Matrix ) was used for truth appraisal.Concepts EmployedBand Ratio TechniquesThe procedure of spliting the pel values in one spectral set by the corresponding pel values in another spectral set is known as set ratioing. It is merely a simple transmutation process applied to remote feeling images. The form of the spectral coefficient of reflection curves of different land screen / land usage types can be identified by this technique. Second it can cut down the recorded unwanted topographic consequence like incline and facet and extinguish the effects of difference in light. The ratioing technique such as spectral flora index are widely utile and benefits the legion subjects like appraisal of biomass, H2O usage, works wellness, harvest production and works emphasis. Vegetation Indices combine different spectral sets, quantitatively step and measure the f lora screen denseness, sort the harvest and besides help in harvest favoritism. The ratioing techniques used in this survey are as followsMin/MaxIt is one of the easy to calculate set ratio technique. It is obtained by taking the ratio between the minimal set value and maximal set value matching to that pel. Ratio Image = Minimum Value/Maximum ValueNDVIOne of the first successful flora indices based on set ratioing was developed by Rouse et Al. ( 1973 ) . They computed the normalized differences of brightness values from MSS7 and MSS5 for supervising flora. They called it the Normalized Differences Vegetation Index ( NDVI ) Jenson 1996. The NDVI is measured in graduated table of -1 to +1. Snow, H2O organic structures, desert and exposed dirts come in a scope of -0.2 to 0.05. While the increasingly increasing sums of green flora come in the scope of 0.05 to 0.7. NDVI informations are strongly correlated with the fraction of exposure synthetically active radiation ( 0.4 to 0.7 A µ.m. beckon length ) absorbed by flora canopies. The brighter the image pel after categorization, the greater the sum of photosynthesizing flora nowadays. NDVI = ( NIR-R ) / ( NIR+R )TVITVI was introduced by Deering et Al. ( 1975 ) . They added 0.5 to NDVI and took the square root, bring forthing the transformed flora index ( TVI ) . The TVI can be linearly correlated with leaf country index, and has a higher sensitiveness than that of NDVI in high biomass country ( Huete et al. , 2002, Sakamoto et al. , 2005 ) . Since the biomass of harvest Fieldss is low compared with woods, TVI retains one-dimensionality in harvest Fieldss. Furthermore, TVI is more practical than NDVI when humidness is high. ( Sakamoto et al. , 2005 ) TVI = a?s ( NDVI + 0.5 )Image Classification TechniquesFor the readying of thematic maps and quantitative analysis of the images, capableness of computing machine to construe the images, place pels and label them based on their numerical belongingss is exploited. The method is normally referred to as Image Classification. While the images can processed in digital environment it is better known as digital image categorization. A traditional difficult categorization technique does non assist in this type of state of affairs. Fuzzy logic may be good where multiple categories exist within a pel. To integrate the assorted pel job in past research workers have proposed the ‘soft ‘ categorization technique that decomposes the pel into category proportions ; fuzzed categorization is a soft categorization technique, which deals with vagueness, ambiguity and uncertainness in category definition. Therefore fuzzed categorization technique is likely the best technique to pull out the individual category from the image and differentiate with other categories. The construct of ‘fuzzy set ‘ theory was introduced by Zadeh, to cover with the uncertainness in category definition. The fuzzed set theory introduces the vagueness by extinguishing the chip boundaries into grade of rank to non-membership map Binaghi et Al. 1999. It represents the state of affairss where an single pel is non a member for a individual bunch, but member for all bunchs with different grade of belongingness Dutta 2009. In this survey fuzzy logic based algorithm, which is independent of statistical distribution premise of informations, has been studied to pull out individual land screen category from distant feeling multi-spectral images. Fuzzy based classifier in this work has been implemented in such a mode that remote feeling image from any detector can be used for individual category extraction.Temporal Data ApproachAt the 3rd degree of categorization where we map the specific flora, mapping based on categorization utilizing individual day of the month image has been merely reasonably successful. The first job in this survey is to pull out individual harvest of involvement from the harsh declaration orbiter image. There is job when pull outing individual category with individual day of the month image. The image consists of pels. A pixel value ( brightness value ) recorded is consequence of interaction of electromagnetic moving ridges with the land objects and/or atmosphere. In add-on harvests may hold similar spectral response forms holding merely little differences. Hence, the spectral response recorded by detector may differ for same or similar type of categories while it may be possible that the dissimilar entities may demo similar spectral response, depending on land or atmospheric conditions. This introduces mistakes. So it is impossible to accurately pull out the individual harvest utilizing the individual day of the month imagination. To get the better of the above issues, temporal informations attack best for specific harvest function. With the clip series informations the spectral response of the category proportions can be recognized and differentiate from other categories. Therefore individual harvest of involvement has been processed utilizing temporal informations.Accuracy AssessmentAccuracy appraisal and proof for sub-pixel classifiers is still a topic of research. No standard methods are available for sub-pixel classifiers, unlike that for hard-classifiers such as mistake matrix and kappa coefficient. For the proof of the consequence, FERM ( Fuzzy Error Matrix, Binaghi et al. ) with the aid of fuzzed set theory based sub-pixel classifier was used in this survey. The truth appraisal of AWIFS fraction images has been done with regard to LISS-III fraction image. The fuzzed mistake matrix ( FERM ) method has been employed to calculate the truth.Classified ImageAssorted PixelReference ImageFigure: Sub-Pixel Acc uracy Assessment Method ( Comparing coarse declaration image with all right declaration image )Fuzzy Error Matrix ( FERM ) :For the appraisal of soft classified informations assorted suggestion have been made, among which fuzzy mistake matrix introduced by Binaghi et al. , 1999 is one of the most suited attack. FERM takes the fraction soft classified images ( drifting value or non-negative existent figure ) as input alternatively of traditional difficult classified images ( integer value ) . The layout of a fuzzed mistake matrix is similar to that of the traditional mistake matrix that is used for accessing the truth of difficult classifiers. The component of the fuzzed mistake matrix represent category proportions, matching to soft mention informations ( Rn ) and soft classified information ( Cm ) , in categories n and m severally. Fuzzy lower limit operator are used to build the fuzzed mistake matrix and find the matrix elements M ( m, N ) in which the grade of rank in the fuzzed interaction ( Cm a? ©aà ‹â€ ? Rn ) is computed as ( Kumar et al. , 2007 ) M ( m, n ) = |Cm a? ©aˆ?Rn| a?‘xI µX min ( A µCm, A µRn ) Where Ten is the proving sample dataset ; x is a proving sample in X and A µCn and A µRn are the category rank of proving sample tens in Rn and Cm, severally. In our survey, fuzzy based mistake matrix was applied for truth appraisal and soft mention informations was generated utilizing IRS-P6, LISS-III temporal informations sets. Producer, user and overall truths of categorization were computed by this fuzzed mistake matrix ( FERM ) truth assessment method.Consequences and DiscussionSample Output ImagesFollowing are the corresponding subdivisions of end product images from temporal informations set-6.Acquisition Date Input Images: Min/Max Band Ratio Image: Concluding Wheat Function21 Nov 2008 C: UsersAmolDesktopImages_ Reporta.jpg C: UsersAmolDesktopImages_ Reportm6_a.jpg 08 Jan 2009 C: UsersAmolDesktopImages_ Report.jpg C: UsersAmolDesktopImages_ Reportm6_b.jpg 27 Jan 2009 C: UsersAmolDesktopImages_ Reportc.jpg C: UsersAmolDesktopImages_ Reportm6_c.jpg 15 Feb 2009 C: UsersAmolDesktopImages_ Reportd.jpg C: UsersAmolDesktopImages_ Reportm6_g.jpg C: UsersAmolDesktopImages_ Reportm6_final.jpg 25 Feb 2009 C: UsersAmolDesktopImages_ Reporte.jpg C: UsersAmolDesktopImages_ Reportm6_e.jpg 11 March 2009 C: UsersAmolDesktopImages_ Reportf.jpg C: UsersAmolDesktopImages_ Reportm6_f.jpg 31 March 2009 C: UsersAmolDesktopImages_ Reportg.jpg C: UsersAmolDesktopImages_ Reportm6_g.jpgCategorization AccuracyTo understand and exemplify the efficiency of the fuzzy set theory based sub-pixel classifier along with assorted sets ratio techniques and temporal informations sets, used in appraisal of specific harvest of involvement, truth appraisal and reappraisal is required.

The truth of categorization of wheat harvest, obtained by using the Min/Max set ratio technique is highest in set-1 and about near to this maximal value in set-6. The truth of wheat harvest mapping utilizing NDVI flora index is maximal in set-6 and same is true for TVI flora index.DiscussionIn this survey fuzzy set theory based sub-pixel classifier has been undertaken for pull outing the individual harvest type ( wheat ) utilizing multi-spectral orbiter images. Three indices Min/Max, NDVI and TVI were used to supervise, estimation and discriminate wheat other harvest types. Fuzzy set theory based sub-pixel classifier which gives the fraction images was applied to band ratio images. Fuzzy Error Matrix ( FERM ) method was applied for truth appraisal of wheat harvest function and proof of the consequences. Irrespective of the figure of images in each multi-date temporal informations set and irrespective the flora index used, this fuzzy set theory based sub-pixel classifier gives reasonably good overall truth, which is ever supra 92.5 % . It thereby establishes certificates of fuzzed set theory based classifier for mapping specific harvest. Further comparative survey of the effects on truth, of flora index used to supervise and know apart wheat harvest shows that, Min/Max flora index is best suited to supervise and know apart wheat harvest while utilizing temporal informations sets. Min/Max flora index gives best truth in half of the temporal informations sets tested. However it does non demo specific form in giving truth as the temporal informations sets vary. TVI flora index besides gives maximal truth in three sets, but the fluctuations, in the truths is maximal. Though NDVI ratio does non acquire the highest topographic point in the truth of categorization, there is some form seen in the truth of categorization under NDVI flora index. It in general additions from set-2 to set-6 which can be explained mistily as better truth for better temporal declaration. Reappraisal of the truth of categorization, with regard to temporal declaration and the day of the months of the images used, suggest that in general overall truth additions from set2 to set6 as the figure of images used addition. Classification truth is highest for set6. As can be seen from Table3, set6 contains images from seeding to harvest home of the harvest and about at temporal declaration of 20 yearss. There is a dip in the categorization truth in set2. That is likely due to inclusion of image of day of the month 6 Nov. 2008 ( before sowing of the harvest ) . It besides explains the dip in categorization truth for set7.Decisions and RecommendationsMotive was to map individual harvest of involvement utilizing fuzzy based classifier with the aid of time-series multi-spectral satellite images. The temporal information helps in favoritism of harvest ( particularly wheat as tested here ) from other harvests. It has been observed from this work that time-series multi-spectral images used for specific harvest function give good overall truth of categorization. Harmonizing to consequences obtained from this work, Min/Max flora index gives maximal truth of function for wheat harvest. NDVI flora index is besides reasonably good and TVI can besides last the intent. Temporal informations set incorporating multi-date images that equally cover the full harvest life rhythm ( seeding to reaping ) gives the maximal accurate function of the harvest. In instance of wheat, the temporal declaration of 20 yearss gives better truth. However, inclusion of images of day of the months other so cropping season ( those before seeding the harvest and after reaping the harvest ) will cut down the overall truth of categorization.

Free Essays on Live Life Free Essays on Live Life Live, Living Life At first glance, Emily Dickinson’s poem #470 seems to be written by a depressed and apathetic person. However, upon further examination, it is clear she is not depressed or apathetic. She is, in fact, enlightened and concerned. Emily Dickinson detests â€Å"accepted society.† She believes it is a void, which one cannot easily escape from, and she feels the need to enlighten her readers and give them ability and drive to break the chains of imprisonment. Dickinson’s consistent and constant use of the same forms of meter, tone, rhythm, and sound brilliantly creates a level of security and stability in the poem, which she destroys in an effort to emphasize the instability, chaos, and false security in â€Å"accepted society,† as well as point out her view of how to overcome these tribulations. Initially, the poem seems to be a call from a very depressed author who â€Å"guesses† she is alive and dreams of her own funeral. While reading the poem for the first time, one immediately falls into the rhythm and â€Å"flows† with the poem. The iambic meter, the meter and style of normal speech, is easy to read and not very taxing on the brain, lips, or eyes.

How to Start a Homeschool Co-Op

How to Start a Homeschool Co-Op A homeschool co-op is a group of homeschooling families who meet on a regular basis to provide educational and social activities for their children. Some co-ops focus on elective and enrichment classes while others offer core classes such as history, math, and science. In most cases, the parents of the students are directly involved in the co-op, planning, organizing, and teaching the courses offered. Why Start a Homeschool Co-Op There are many reasons that a homeschool co-op  Ã¢â‚¬â€œ large or small  Ã¢â‚¬â€œ can be a beneficial endeavor for parents and students alike. Some classes simply work better with a group. It can be hard to find a  chemistry lab partner at home, and unless you’re doing a one-man play,  drama needs a group of kids. Sure, you may have siblings or a parent who can help out, but for activities such as science labs, it can be beneficial for students to work with their peers. In  a co-op setting, kids learn how to work with a group of students. They can practice vital skills such as delegating tasks, doing their part to make the group activity a success, and resolving conflicts when disagreements arise. A co-op provides accountability. You know those classes that tend to fall by the wayside? Starting a small co-op is an excellent way to prevent that by adding a layer of accountability. You may find that you have good intentions, are continually pushing aside enrichment classes such as art and nature study. When youre meeting with a few other families, youre more likely to follow through on the classes. It’s much easier to stay the course when other people are counting on you. A co-op is a great solution for teaching difficult subjects or skill-based electives.  A co-op can prove to be the perfect way to tackle subjects like  high school level math and science courses or electives for which you lack the knowledge or skill set. Maybe one parent can teach math in exchange for another sharing her talent for art or music. If you know a parent with a unique skill, such as photography or fluency in a foreign language, they may be willing to offer group classes for a fee.  Ã‚   A co-op can make the subject  more fun for the students. In addition to the prospect of greater accountability, a co-op can make a  boring or difficult subject more fun for the students. While the class may still be dull or complicated, the prospect of tackling it with a few friends can at least make the class more palatable. The students might even find the course fun with an instructor and one or two students who display enthusiasm for it, or who have a good grasp on the topic and can explain it in easy-to-understand terms.   Homeschool co-ops can help kids learn to take direction from someone other than a parent. Kids benefit from having instructors other than their parents. Another teacher  may have a different teaching style,  way of interacting with children, or expectations for classroom behavior and due dates. It’s useful for students to learn  to interact with other instructors so that it’s not such a culture shock when they go to college or into the workforce or even when they find themselves in classroom settings within the community. How to Start a Homeschool Co-Op If you’ve decided that a small  homeschool co-op would be beneficial for your family, it’s relatively straightforward to start one. While you needn’t worry about the complex  guidelines that a  larger, more formal co-op would require,  a small, informal gathering of friends still calls for some ground rules. Find a meeting place (or establish an agreed-upon rotation). If your co-op is going to be only two or three families, you’ll likely agree to gather in your homes. You may also be able to use a room or two at a   library, community center, or church. Wherever you meet, be considerate. Offer to help clean up afterward.  Arrive on time.Start on time. It’s easy to get caught up in socializing for the students and their parents.Leave promptly after the class is over. The  host family may have school to complete or appointments on their calendar.Ask if there is anything you can bring or do to simplify hosting. Set a schedule and guidelines. Small groups can disintegrate quickly if one or two people have to miss the class. Set a schedule at the beginning of the year, taking holidays and any known date conflicts  into consideration. Once all the parents have agreed to the calendar, stick to it. Make arrangements for students who have to miss class to make up the work. If youre completing a DVD course, perhaps students can borrow the DVD set and complete the assignment on their own. For other classes, you may consider making copies of materials or having another student take notes for those who are absent. Be sure to build a few flex days into your calendar for the inevitable disruptions such as inclement weather or times when multiple students are sick or unable to attend class. You will also want to determine how long and how often each class will meet and set start and end dates. For example, will this be a year-long or single semester co-op? Will you meet one hour twice a week or two hours once a week? Determine roles. If the course needs a facilitator or instructor, determine who will fill that role. Sometimes these roles fall into place naturally, but make sure that all the parents involved are okay with the tasks that fall to them so that no one feels unfairly burdened. Choose materials. Decide what materials you’ll need for your co-op.  Will you be using a particular curriculum? If you are piecing together your  own course, make sure everyone knows who is responsible for what. For example, if youre teaching an  art co-op, one parent may already own the curriculum that youll be using, so each student would just need to purchase their own supplies based on a materials list provided by the  instructor.For a DVD course, one parent may already own the DVD set required, and each student would need only to purchase their own workbooks. If you’re buying materials to be shared by the group,  such as a DVD set or a microscope, you  will probably want to split the cost of the purchase. Discuss what you’ll do with the non-consumable materials after the course is over. One family may want to buy out the other family’s share to save something  (such as a microscope) for younger siblings, or you may wish to resell  non-consumables and split the proceeds between the families.   Identify age-ranges. Decide what age students your co-op will include and set guidelines for older and younger siblings. If youre teaching a high school chemistry course, it will be distracting for parents and younger siblings to be chatting in the corner. So decide from the beginning if younger siblings will need to stay at home or if there is another room where they could play under the supervision of a couple of parents. You may also want to consider ability-level rather than age. For example, a wide range of ages could learn a foreign language together depending on what level of reading and writing are involved. However you choose to structure it, a small homeschool co-op with a few families is an excellent means of providing  the accountability and group atmosphere that you may be missing in your homeschool.

Violence in the Binding of Isaac Essay Example | Topics and Well Written Essays - 250 words

Violence in the Binding of Isaac - Essay Example And while there is the aspect of child abuse as background story, we cannot deny the fact that it is overshadowed by violence and that gamers want to play not because they want to see why and how Isaac was being abused but to be able to go to Isaac’s violent imaginary world (Giantbomb Website), If the designer wanted to use his game to inform people about child abuse, I must admit that he succeeded and I admire him for it. But the point here is that the game, while opening the gamers’ eyes on child abuse, seems to teach that violence is the answer. Isaac, on being pushed to a corner resorts to imagining himself in violent situations where he must win in order to get a prize and feel good. And as a gamer is elevated to another level, he will again battle his way to get out of that level. While it is true that the game was created for adults, children today have easy access to computers and when unsupervised, they can get access to, and play this adult game. The designer, in using child abuse as the main story in the game and violence as an answer to forget pain, unwittingly encourages gamers to accept violence as just. The danger of such video games is that we never know if and when a player will soon be so absorbed that his sense of justice and what is right and wrong will be so muddled that there will come a time when he will unintentionally cross the

Cell Phones VS Landlines; the Advantages and Disadvantages Research Paper

Cell Phones VS Landlines; the Advantages and Disadvantages - Research Paper Example nine percent of Americans use cell phones only with no landlines though most Americans combine the use of both landlines and cell phones (Westcott, p41). A cell phone is a short-range communications device that receives and broadcasts low power digital radio signals to and from cell sites which are located throughout populated areas. Older cell phones transmitted analogue signals with some transmitting both digital and analogue signals until 2008 when the support of analogue signals stopped. On the other hand, landline phones are usually linked to a main central utility via telephone lines. Local regulatory commissions normally control the pricing of landline use. Traditionally, landlines were the ones used for homes and offices but nowadays more people have switched to cell phones. This presentation seeks to examine the pros and cons of cell phones and land lines from different perspectives in terms of their use and possession and provide one with knowledge to enable him or her make an informed decision when choosing to have one or both telecommunication devices. Portability: Unlike land lines, cell phones are very portable and one can carry them along anywhere and use them anywhere where there is a service provider signal. They can be conveniently carried around and used in places where land lines are absent, for example while on the highways. Mobility: One can use cell phones while on the move and hence save a lot of time which would have been wasted by being stationary and waiting for the phone call, especially for a busy individual. Besides, one does not have to miss important calls while on the move. Emergencies: In cases of accidents, one can easily call the ambulance or police while at the scene. One can even take pictures of the accident scene if he has a phone with a camera. In cases where one may be lost, one can call for directions or if he has a GPS enabled phone, the emergency services can trace his position and come to his rescue. Versatility:
