Setting up the worldview. How would we know there is a God? In the event that anything exists there is a God since you can't make something from nothing.

Learn about our editorial policy Kendra Cherry Updated on August 05, 2019 Alain SHRODER / ONOKY / Getty Images More in Student Resources Careers APA Style and Writing Study Guides and Tips Broadly speaking, psychologists study the mind and behavior, but because psychology is such a diverse field, the work that individual psychologists do can vary dramatically. They often specialize in a specific area, for example, and there are myriad of psychology specialties. Heres an overview of the ways in which a psychologist might funnel his or her expertise into a career. Two Types of Psychology Work Psychologists may work in a wide variety of settings, including schools, universities, hospitals, private clinics, government offices, corporations, and small businesses. Psychologists primarily work in one of two broad areas: research psychology or applied psychology. Research psychologists investigate the physical, emotional, social, cognitive, and biological bases of human thought and behavior. They often conduct experiments and may work at a college or university, or be employed by a business or government office. Applied psychologists use their knowledge of human behavior to solve real-world problems or help people overcome psychological distress. Applied psychologists may work directly with patients in a healthcare setting, such as in a hospital, mental health clinic, school, or private practice. Other applied psychologists may work in government, industry, business, or nonprofit settings. In addition to applying their knowledge of psychology directly, these professionals also may perform research, offer training, design products, create programs, or provide psychological advice. A Day in the Life of a Psychologist Psychologists employed in research settings often spend a great deal of time developing hypotheses and collecting data. The exact research methods they use depend largely on the topic theyre studying. For example, some psychologists might perform research using lab experiments, while others might use naturalistic observation. Other methods commonly used include administering questionnaires, clinical studies, surveys, and interviews. Psychologists employed in health care settings often spend a considerable amount of time working directly with clients. This might involve conducting assessments of new patients, diagnosing mental disorders, and performing psychotherapy. Psychologists also frequently consult with other health professionals, including doctors, nurses and other therapists. Specialty Areas in Psychology Here are some examples of the richly diverse specialties that make up the field of psychology. Clinical psychologists make up the single largest specialty area in psychology. Clinicians are psychologists who assess, diagnose, and treat mental illnesses. They frequently work in mental health centers, private or group practices, or hospitals. Within the area of clinical psychology, there also are a number of sub-specialty areas. Some professionals are generalists and work with a wide range of clients while others specialize in treating certain types of psychological disorders or a certain age group. For example, some clinical psychologists might work in a hospital setting with individuals suffering from brain injuries or neurological conditions. Other clinical psychologists might work in mental health centers to counsel individuals or families coping with stress, mental illness, substance abuse, or personal problems. Clinical psychologists usually perform a broad range of tasks on a daily basis, such as interviewing patients, conducting assessments, giving diagnostic tests, performing psychotherapy, and administering programs. They might work in a hospital, school, university, prison, mental health clinic, or private practice. There also are a number of different sub-specialty areas within clinical psychology, including health psychology, neuropsychology, and geropsychology. According to the Occupational Outlook Handbook, health psychologists are focused on promoting healthy behaviors. Neuropsychologists focus on investigating the relationship between the brain and behavior. Geropsychologists specialize in treating the special concerns of elderly populations. Counseling psychologists make up another large specialty area in psychology. These professionals perform many of the same tasks that clinical psychologists do, but counseling psychologists tend to work with clients suffering from less severe forms of mental illness. Counseling psychology focuses on providing therapeutic treatments to clients who experience a wide variety of symptoms. The Society of Counseling Psychology describes the field as a psychological specialty [that] facilitates personal and interpersonal functioning across the lifespan with a focus on emotional, social, vocational, educational, health-related, developmental, and organizational concerns. Experimental psychologists (or research psychologists) conduct research on the behavior of humans and animals. They often work at universities, private research centers, government agencies, and nonprofit organizations. Some major areas of research include substance abuse, genetics, neuroscience, motivation, and cognitive processes. Forensic psychologists work in the specialty area that deals with the intersection of psychology and the law. Forensic psychologists are often involved in custody disputes, insurance claims, and lawsuits. Some professionals work in family courts and offer psychotherapy services, perform child custody evaluations, investigate reports of child abuse and conduct visitation risk assessments. Those working in the civil courts often assess competency, provide second opinions, and provide psychotherapy to crime victims. Professionals working in the criminal courts conduct evaluations of mental competency, work with child witnesses, and do assessments of juvenile and adult offenders. Social psychologists are focused on understanding how interactions with other people impact individual and group behavior. These professionals often work in areas such as market research, organizational management, systems design, and other applied areas. Prominent areas of study include group behavior, leadership, attitudes, and perception.

Essay on Desire in The Taming of the Shrew, by William...
People have always gone out of their way to obtain what they desire in their life. Whether this obsession is out of greed or true necessity, a person will go to great lengths to achieve it. In the novel, The Taming of the Shrew, written by William Shakespeare, we find this trait present within the characters: Lucentio, Hortensio, Gremio, Petruchio, and Katherine. Each of these characters has their own motivation behind their actions in this story. Hortensio and Lucentio each wish to woo Bianca and take her as their bride. Hortensio, in an effort to secretly pursue the young woman, dons the appearance of a music teacher who goes by the name of Litio. After having shared information with Petruchio about Katherine, heâ⬠¦show more contentâ⬠¦To accomplish this he marries the shrew, Katherine, in hopes of receiving a wealthy dowry from her father. Despite the numerous warnings Hortensio gives him, Petruchio casts them aside saying ââ¬Å"thou knowââ¬â¢st not goldââ¬â¢s effect â⬠(1.2.94). Again desire prevails over necessity. Here is a man whose desire for wealth eclipses the possible chance of happiness being found within his new wife. The greed does not end there, however, Petruchio goes so far as to tame Katherine to acquire even more funds through a bet made with Hortensio and Lucentio in the end. The three men get into a minor argument, each claiming their wife to be the most obedient. To settle this dispute, Petruchio proposes ââ¬Å"Letââ¬â¢s each one send unto his wife, /And he whose wife is most obedient/To come at first when he doth send for her/Shall win the wager which we will proposeâ⬠(5.2.68-71). The men then settle on an amount of one hundred crowns after some negotiation. While Petruchio is quick to win the bet, as Katherine is the first to arrive, his greed has provided him even more money at the cost of abusing a woman in attempts to break her independence. Quite often, desire has the ability to blind someone from thinking logically. For Gremio, his affection for Bianca put him in this situation. Early on, Hortensio formulates a plan to find a man to marry Katherine, allowing Bianca to be available for marriage.

Sri lanka agriculture development and rural economy Free Essays
Dependency theory was really popular during 1960s and 1970s as a direct challenge to the free market theory which was popular during the post-war season. The theory was formulated in 1950s and it is drawn on Marxian analysis of planetary economic system. The theory explains the relationship between economically developed states ( Advanced states ) and developing states of the universe. We will write a custom essay sample on Sri lanka agriculture development and rural economy or any similar topic only for you Order Now Harmonizing to the theory, the developed states consider as the nucleus of the system and the developing states as the fringe of the system. When the system is working, resources flow from fringe developing states to the developed nucleus states. It is a cardinal contention of dependence theory that hapless provinces are impoverished and rich 1s enriched by the manner hapless provinces are integrated into the ââ¬Å" universe system. â⬠The dependence theory is applicable to most of the developing states in the universe except few illustrations like India and Taiwan. Harmonizing to my cognition the theory is applicable to all most all states in the south Asia including Sri Lanka. Sri Lanka was besides colonized by British Empire during 1815 ââ¬â 1948 where it made a terrible harm to the Local civilization, Social life, independence every bit good as Economy. Even though the state has been ruled by local leaders from 1948, United Kingdom and other developed states have been created negative consequence on the development of the state. However, presently Sri Lanka is in a right tract toward the development, where the service sector and the fabrication sector shows a fast growing while the Agriculture sector shows a relatively slow growing. Tourism and other service subsectors have been well contributed to the economic system of the state. However the economic system of the state was opened to the universe market in 1977 and the state has been experienced both positive and negative impacts on the development positions. On the one manus most of the local baby industries were collapsed during the period as a negative consequence of the unfastened economic system. On the other manus most of the international investors and multinational carbon monoxide operations came to the state with their new engineerings which was utile to look in the universe market as a bring forthing state. Most of the developing states specially in south Asiatic states, including Sri Lanka have been depend on the IMF, World Bank, ADB and other multinational carbon monoxide operations to carry through their budget shortage through loans or grants under legion regulations and ordinances which severely consequence on the internal development. As consequence of that influence, most of those regional leaders every bit good as people of those states have a dependence outlook which was identified as the major constrain for the development. However, Sri Lanka was able to come in the in-between income state degree and presently the dependence outlook remains merely in some portion of rural countries of the state. In that scenario, Sri Lanka is no longer stray state in the universe, but still in the disadvantaged and developing side which needs particular protection and nutriment for local baby industries to protect them from the international competition. Consequently, Sri Lanka has to utilize different theoretical account which can pull strings the international competition within the state while absorbing the maximal public-service corporation form the international market. Harmonizing to my cognition and experience no any pure theory will helpful to utilize as it is for development in any state. Therefore, the state must hold their ain manner for development which has to critically see their ain resources and restrictions. ââ¬Å" Poor but efficient Agriculture usage of developing state Traditional system â⬠proposed by T.W. Schultz. This is one of a theory which tries to explicate the efficient usage of limited resources by hapless or developing husbandmans in developing states. The theory was foremost found in the T.W. Schultz ââ¬Ës book of Transforming Traditional Agriculture which was published in 1960s and the theory was really popular during that period. During 1950s and 1960s, Most of the economic experts and Policy shapers believed that the productiveness of Agriculture sector in developing states as really low. Therefore they argued that the fringy productiveness of the labor in those states as nothing. Hence those agribusiness labors could be transferred from the agribusiness sector to the industrialisation sector without holding any harm to the agribusiness sector. Therefore, it was besides widely accepted that husbandmans in developing states were guided by tradition or civilization. On the other manus they are non responded to the economic inducements. But Schultz argued that the husbandmans in developing states have really limited resources but most of the husbandmans use that limited resources expeditiously. However those husbandmans are hapless because of the other assorted grounds like cultural features such as deficiency of a work moral principle, deficiency of an apprehension of the thought of salvaging, or general ignorance of how to do best usage of their resources. Schultz argued that low income degrees in developing states agribusiness are a consequence of the low productiveness of the available factors of production, but non inefficiencies in their resource allotment. Subsequently, most of the researches have been conducted and accordingly the theory was through empirical observation proved utilizing the research conducted in several developing states. In Sri Lanka, there are plentifulness of little graduated table husbandmans who live under the poorness line but they use their limited resources expeditiously for their harvest cultivation. Water and fertiliser is the most scare resources in the dry zone of Sri Lankan husbandmans. They use particular agriculture pattern which is called as ââ¬Å" Chena cultivation â⬠. Even though that agriculture pattern is non recommended by most of the agriculturalist in the state, Chena cultivation is one of the largely adoptable patterns to utilize H2O and fertiliser. In this method husbandmans ever use new piece of land and they move to new a land in the following season. Farmers use all the vegetive parts as green manure and fire all the difficult parts of workss and mix with dirt as fertilisers. That organic manure covers all the alimentary demand of the new harvests. Farmers cultivate drought immune harvest varsities and cultivate as a mix harvest form. The system lowers the hazard of plague and disease incidence and good as maximise the use of wet. Farmers normally use household labors and utilize some excess labor merely in peak seasons. However, most of those husbandmans are hapless and the life base is besides low. There are many grounds behind the narrative and some of them are low salvaging rate, hapless cost direction, selling jobs, low substructure etc. In that sense, even today, the theory is applicable in most of the developing states and it is utile to understand their agriculture manner, populating manner of the husbandmans. On the other manus, it is utile to propose them to rectify their failings. How to cite Sri lanka agriculture development and rural economy, Essay examples

Time As A Determinate Of Final Product free essay sample
In A Dehydration Reaction Essay, Research Paper Time as a Determinate of Final Product in a Dehydration Chemical reaction Robert Simack, Department of Chemistry and Biochemistry, University of Alaska Fairbanks, Fairbanks, Alaska. Abstraction: This survey involved acerb desiccation of 2-methylcyclohexanol. The consequences varied depending on the clip elapsed after initial reaction. I attempted to turn out the Evelyn Effect, which stated that over a period of clip the merchandises of the aforesaid reaction will beobserved to alter volume so that those merchandises formed by a cis isomer of 2-methylcyclohexanol will organize foremost. However, one time all molecules in the Commonwealth of Independent States isomer undergo reaction the staying trans configured 2-methylcyclohexanols will proliferate during the latter period of the reaction. I besides postulated as to the possible preparation of 1-ethylcyclopentene, and to the cause of such an event. Introduction: After researching acid-catalyzed desiccation reactions ( McMurray ) and background on the Evelyn Effect ( Clausen ) I hypothesize that the cis isomer of 2-methylcyclohexanol will respond via an E1 type procedure organizing 1-methylcyclohexene harmonizing to anticipations from Zaitzev? s regulation ( Lehman ) . We will write a custom essay sample on Time As A Determinate Of Final Product or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page This should be due to the fact that the Commonwealth of Independent States isomer has 2 anti-coplanar Hs. These two Hs should do the molecule more reactive. The trans isomer, with merely one anti-coplanar H, should be slower to respond and will organize a 3-methylcyclohexene. In add-on the 1-ethylcyclopentene will be formed from both the Commonwealth of Independent States and trans isomers but merely if the hydroxyl group is in an equatorial place. In that place negatrons from the ring may assail the intoxicant straight from behind forcing it off the ring and organizing a 5-membered ring alternatively. Results A ; Discussion: An NMR ( 300MHz ) spectra of the original reagent and the three fractions provided a immense sum of information in support of my hypothesis. Both Commonwealth of Independent States and trans isomers were present in the spectra for the original stuff every bit good as for the first two fractions. The intoxicant? s H showed up at about 3.79 and 3.1 for Commonwealth of Independent States and trans severally. In the spectra for pure get downing stuff ( ref: Jim Starr /Steve Standish NMR 24 March, 2000 ) Commonwealth of Independent States isomers of get downing stuff comprised merely 25 % of the sample compared to 75 % of trans as observed in the integrating of extremums. In the spectra for fraction one a 3:1 ratio of trans to cis was observed. In the spectra of fraction two the Commonwealth of Independent States isomer about disappeared ; the ratio was approximately 6:1 trans/cis. Finally, in the spectra of the 3rd fraction the Commonwealth of Independent States isomer was perfectly unperceivable while the integrating of trans was about twice that of the integrating from fraction one. These spectra show that Commonwealth of Independent States reacted first and was rapidly consumed by the reaction go forthing trans isomers to complete the reaction. Because it is kn ain that the reaction with cis get downing stuff caused both 3-methylcyclohexene and 1-methylcyclohexene I postulated that the first merchandise of the latter phases of the reaction must be 3-methylcyclohexene, which is the exclusive merchandise of the trans reaction ( McMurray, fellow. 11.12 ) . In add-on to the Commonwealth of Independent States and trans peaks the extremum for both 3-methylcyclohexene and 1-methylcyclohexene could be found on the spectra at 5.7 and 5.4 severally. The NMR showed that the integrating of 1-methylcyclohexene dropped merely somewhat throughout the reaction while the integrating of 3-methylcyclohexene increased about tenfold. The findings from the spectra prove the hypothesis that the Commonwealth of Independent States reaction will travel the fastest followed by the trans because as the Commonwealth of Independent States is consumed it? s extremum at 3.79 will diminish every bit good as the extremum for 1-methylcyclohexene due to expiration of that mer chandises formation. Besides, extremums for 1-ethylcyclopentene Begin to demo in the spectra for the 2nd fraction and increase in size ( country beneath the extremum ) by the spectra of the 3rd fraction. At the root of this phenomena is steric hindrance. Both the Commonwealth of Independent States and trans isomers will organize 1-ethylcyclopentene ( fig. 1 ) . However, because of steric hindrance the trans isomer is favored to organize the 1-ethylcyclopentene. This fact will explicate why more of the pentene shows up in the 3rd fraction. Finally, a bantam extremum showed at 4.6 in every fraction? s spectra bespeaking the presence of methylenecyclohexane. This merchandise formed from the original merchandise by acerb accelerator. Experimental: An setup was constructed with a unit of ammunition underside flask topped by a claisen adapter in which was placed a thermometer and a condensation tubing. In the setup 150mmole of 2-methylcyclohexanol was assorted with 5mL H3PO4 and distilled. The distilled liquid was collected in three tubings, at about 4mL per tubing, labeled fraction 1, 2 and 3. Each fraction was placed in a extractor tubing and combined with 4mL concentrated NaHCO3. The aqueous bed was removed and MgSO4 was added for a concluding separation. The solid and aqueous beds were so removed and the concluding merchandise was combined with CDCL3 in an NMR tubing in readying for spectra. The liquid staying in the original setup was put through the separation procedure described above. However, alternatively of CDCL3 as a spectrum reagent we used CH2CL2. Besides, an NMR was non performed on the staying liquid but alternatively a GC.
