Psychology reporting on gender differences in rumination and reflection Free Essay Example, 1000 words

According to Butler and Nolen-Hoeksema, rumination as a form of coping with depression represent â€Å"a type of self-focused attention, an an emotion-focused attention† (Butler and Nolen-Hoeksema, 1994, p. 332). In their study, Butler and Nolen-Hoeksema (1994) found that women unlike men report that when depressed they focus on themselves and their emotions, and avoid activity. Researchers indicated that male subjects overall did not show distracting response style and throughout the study males revealed â€Å"their lower likelihood of emotion-focusing or ruminating, compared to women† (Butler and Nolen-Hoeksema, 1994, p. 341). Almeida and Kessler (1998) explained that rumination theory, based on cognitive-behavioral thinking, states that gender differences in depression and stresses occur due to differences in how men and women respond to being in a dysphoric state. As Almeida and Kessler (1998) suggest, by being likely to ruminate on their negative emotions, women tend to prolong them (p. 670). In their study Almeida and Kessler (1998) found that among husbands and wives, female sample experienced more distress episodes than men and women were generally likely to remain in stress during more days.

In addition, rumination revealed the gender differences in depressive symptoms (Nolen-Hoeksema et al, 1999). According to suggestions made by researchers (Nolen-Hoeksema et al, 1999), women’s tendency to ruminate may be explained through their desire to control environment and distress. However, their failure to impose this control lead to situation when women remain stuck in rumination. In another study examining bereaved adults, Neol-Hoeksema et al (1994) indicated that individuals who in grieving cope with negative emotions with rumination experience significant difficulties adjusting their loss, placing themselves at risk for long-term emotional difficulties. In a study aiming to find and explain gender differences on the experience of depression, Thayer et al (2003) indicated that women reported greater feelings of sadness , unattractiveness, guilt, blame and tiredness compared to men. Simultaneously, women reported more problems with decision-making, task accomplishment and more weight associated problems than men. Noel-Hoeksema and Jackson (2001) examined beliefs about control of emotions, responsibility for the emotional tone of relationships, and mastery over negative events of both male and female samples, and concluded that these variables revealed the gender difference in rumination.

Chicano Gangs And The Los Angeles - 3699 Words

Chicano gangs have been a prominent part of the Los Angeles community since the early 1900s. These Chicano gangs consisted of young Mexican-Americans, another name used for Chicanos, which were formed as a way for some youth to identify with something. The behavior of gang members was a way of adapting to the social and economic living situation that was upon them. There was a large migration of Chicano immigrants to the Los Angeles area that resulted in several changes directly related to the larger and present Chicano presence. The most notable being the prominent presence of Chicano specific gangs. This is likely due to the fact that many people of Chicano descent are immigrants who came to America with little to nothing. This resulted in large groups of Chicanos being located in some of the poorest areas. Such areas became known as â€Å"barrios†, a Spanish term for neighborhood that became specifically in reference to the poor neighborhoods with a high Latino population. The people living in them were often working the lowest paid and hardest jobs needed by those of a higher class in society. It is commonly found that when poverty is heavy throughout a community, many youth will feel the need to act out in some way, and band together in their mutual discontent with their surrounding environment and society. In addition, many youth were also dealing with trying to identify themselves as something and weren’t sure if to identify themselves as latino, chicano, or somethingShow MoreRelatedSocial Movements Created by Mexican Americans1447 Words   |  6 PagesCalloway had inspired many of the young African Americans and Hispanics during his performances, which later changed to a form of expression on individuality, freedom and rights.

Kinetic Free Essays

We can use many of Technique or methods for separating of compounds or mixtures .and we can by those methods studying of kinetic for reactions ,determine of reaction rate and reaction order . some of those methods are : mass spectrometric , spectrometric and Chromatographic Methods . We will write a custom essay sample on Kinetic or any similar topic only for you Order Now But in this paper I just talk about chromatographic method . exactly, gas chromatography . Chromatography:Few methods of chemical analysis are truly specific to a particular analyte. It is often found that the analyte of interest must be separated from the myriad of individual compounds that may be present in a sample. As well as providing the analytical scientist with methods of separation, chromatographic techniques can also provide methods of analysis . Chromatography involves a sample (or sample extract) being dissolved in a mobile phase (which may be a gas, a liquid or a supercritical fluid). The mobile phase is then forced through an immobile, immiscible stationary phase. The phases are chosen such that components of the sample have differing solubility in each phase. A component which is quite soluble in the stationary phase will take longer to travel through it than a component which isn’t very soluble in the stationary phase but very soluble in the mobile phase. As a result of these differences in mobilities , sample components will become separated from each other as they travel through the stationary phase. Gas chromatography methods that are used for studying first-order reaction kinetics by gas chromatography : (1) classical kinetic methods where samples of batch-wise kinetic studies are analyzed by enantioselective gas chromatography, (2) stopped-flow methods performed on one chiral column, (3) stopped-flow methods performed on an achiral column or empty capillary coupled in series with two chiral columns, (4) on-flow method performed on an achiral column coupled in series with two chiral columns, and (5) reaction gas chromatography, known as a dynamic gas chromatography. The following procedures have been developed to determination peak areas of reaction constituents in such complex chromatograms: (i) methods based on computer-assisted simulations of chromatograms where the kinetic activation parameters for the interconversion of enantiomers are obtained by iterative comparison of experimental and simulated chromatograms, (ii) stochastic methods based on the simulation of Gaussian distribution functions and using a time-dependent probability density function, (iii) approximation function and unified equation, (iv) computer-assisted peak deconvolution methods. Fast reaction :Reaction between metal carbonate and acid.- Reaction between calcium carbonate and hydrochloric acid :CaCO3 + 2HCl -; CaCl2 + H2O + CO2Reaction between reactive metal and water .-reaction between lithium and water :2Li + 2H2O -; 2LiOH + H2Combustion .-combustion of magnesium in oxygen .2Mg + O2 -; 2MgOPrecipitation (double decomposition )-precipitation of silver (I) chloride :AgNO3 + HCl -; AgCl + HNO3 Rate :The rate can be measured using apparatus on the rightrate of reaction = d[CaCl2] / t ,or d[CO2] / t or d[H2O] the rate can be decrease or increase with change of temperature , concentration , pressure , surface area or size of molecules .concentration : when the concentration is decrease the rate decrease .example : 3 g of calcium carbonate react with 5 g of hydrochloric acid to produce 3 g of carbon dioxide in 10s at 25C and 1atm. rate = -d [CaCO3] / t = -d[3] / 10 . But we decrease of concentration of calcium carbonate to 2 .rate = -d[2] / 10 .pressure and temperature : also when decrease the pressure or temperature the rate decrease .example : 3 g of calcium carbonate react with 5 g of hydrochloric acid to produce 3 g of carbon dioxide in 10s at 25C and 1atm. rate = -d [CaCO3] / t = -d[3] / 10s . but the time is increase to 20s , because the pressure decrease to 0.5 and temperature decrease to 15 , so the rate = -d [3] / 20s . In a chemical reaction the reactant decrease over time and product increase over time . The rate will decrease over time as the hydrochloric acid is used up (its concentration decreases)The graph in after page shows the volume of gas produced over time in the reaction between HCl and CaCO3 .All three reactions result in the same amount of CO2 gas being produced; however the higher the concentration of HCl, the faster the rate of reaction, thus the less time it takes for the reaction to be complete . The table below shows the time taken to produce 50cm3Â  of CO2Â  for each concentration of HCl :Rate of reaction / cm3 of CO2 s-1 Time take to produce 50 cm3 of CO2/1s Concentration of HCl /mold m-30.86 58 2.00.42 120 2.00,21 235 0.5 From the results in the table above, it can be worked out that the rate of reaction is directionally proportional to the concentration of hydrochloric acid, so if you halve the concentration of HCl will be halved, if you quarter the concentration, the rate will be quartered . rate = k [HCl]1 Order :The order of a reaction is not necessarily an integer. The following orders are possible :Zero: A zero order indicates that the concentration of that species does not affect the rate of a reaction .Negative integer: A negative order indicates that the concentration of that species INVERSELY affects the rate of a reaction .Positive integer: A positive order indicates that the concentration of that species DIRECTLY affects the rate of a reaction . Non-Integer: Non-integer orders, both positive and negative, represent more intricate relationships between concentrations and rate in more complex reactions.So, in The reaction of calcium carbonate with hydrochloric acid is said to be first order with respect to hydrochloric acid .This is because the rate depends upon the concentration of hydrochloric acid to the power one . Technique :we can measure of rate of carbon dioxide by gas chromatography , gas chromatography can separating of compound by boiling point , and you can analyze results on your computer and measuring of rate of CO2 .and you can determine of rate by flow reaction that may be is easer method .

Diuretics Used in Sport free essay sample

Diuretics dilute urine which can often help pass drugs tests. It is important that drugs such as diuretics are identified and managed in sports performance. This is especially true at elite levels as athletes have an unfair advantage when taking drugs to improve success. The use of research questions can help the understanding of drugs such as diuretics being used in sport. For research questions to be beneficial they have to be all of the following: Specific, measurable, achievable and realistic. Below are 4 specific research questions based around diuretics being used at elite levels in sport. By identifying research questions, understanding of the problem is increased: 1. To what extent can diuretics be used to improve an athlete’s performance? The use of this research question will allow the understanding of the physiological effect diuretics have on the body of an athlete. Article: Drugs in sport: Diuretics and masking agents. Mottram. 2. What is the relationship between diuretic consumption and the masking of performance enhancing drugs? Answering this research question will allow the understanding on how diuretics can be used as a masking agent for other performance enhancing drugs. Article: Exercise and sports nutrition: Principles, Promises, science and recommendations. Krieder et al. 3. What would be the overall effects on sport if the ban on diuretics and the drugs they mask was lifted? By answering this research question, the ethics behind sport and fair play can be understood. Article: Anti-doping policies: New directions, Waddington and Smith. 4. What effects does the long term use of diuretics have on dehydration? Answering this research question will help the understanding of the effects of changing the natural balance of fluids in the body and how they can affect the liver causing dehydration. Article: Performance enhancing drugs in sport and exercise, Bahrke and Yesalis 5. What effect doe duretics have on cell structure The question being used for the remainder of this essay is: What would be the overall effects on sport if the ban on diuretics and the drugs they mask was lifted? This question can be used to understand the issues around the use of diuretics in sport. By using this research question Academic disciplines which provide theorectical underpinning to the research This question can help the understanding of the psychological effects on using diuretics. Allowing the use of diuretics in sport would affect athletes psychologically by making them feel superior and confident about their performance. However if performance enhancing drugs were legalised in sport, athletes would have unfair advantages. Diuretics are commonly used in sports which have weight categories such as boxing and body building In order to collect data from the research question, it has to be operationalised. Design Sample Instrumental Data analysis One problem with validity, one with reliability and one with ethics Validity To answer this I looked at what validity is in research terms. Basically validity is whether the research is really measuring what it claims to be measuring and as objectively as it says it is. Is the researcher really looking to prove a point or disprove a point and in doing so have they used a) Valid research questions to measure the required information and b) Is the research really measuring what is says it is measuring It is not difficult to see that if the answer to the above questions are both â€Å"no† then the research must be said to be invalid Reliability Reliability looks at whether the research can be reliable in as much as can it be applied to a wider group with confidence that the same or similar results will follow thus making the research reliable. It is clear that reliability has a direct link then to sample sizes and sample validity and the spectrum of the sample, for example if a piece of company research only sampled 50 of its customers from 20,000 customers all of whom had completed a satisfaction survey and returned it with positive result in the past, could this be said to be a reliable as it has clearly taken a relatively small sample and unethically used past known positives? It can be seen that the data capture process or research methods have a big impact on reliability. Ethics Again I sought to answer this question by looking at what ethics was in both normal everyday situations and in research terms. In both cases it appears to be about morals and right and wrong. The debate in research terms seems to be a very large one, however I came across this statement â€Å"†¦.. our assumption is that academic freedom does not confer a right to do research Anthropology Matters Journal 2010, Vol 12 (1) http://eprints. oas. ac. uk/10352/1/The_problem_of_ethics_in_contemporary_anthropological_research. pdf From this and further reading I think the single biggest problem with research ethics is different people have different ethical value bases and believe different things are right and wrong. It is clear however that if the ethical basis of the research can be easily attacked then it validity and reliability must both come into question. It is also clear that different sectors of society may take different views from different perspectives i. e. a financial institutuion may take a different view than a church.
