Education in the Philippines Essay
In psychology, a drive theory or drive doctrine à is a theory that attempts to define, analyze or classify the psychological drives. A drive is an ââ¬Å"excitatory state produced by a homeostatic disturbanceâ⬠, an instinctual need that has the power of driving the behaviour of an individual. Drive theory is based on the principle that organisms are born with certain psychological needs and that a negative state of tension is created when these needs are not satisfied. When a need is satisfied, drive is reduced and the organism returns to a state of homeostasis and relaxation. According to the theory, drive tends to increase over time and operates on a feedback control system, much like a thermostat. Psychoanalysis Early attachment theory Social psychology Corroborative evidence Evaluation apprehension See Also ReferencesIn Freudian psychoanalysis, drive theory (German: Triebtheorie, German: Trieblehre) [1] refers to the theory of drives, motivations, or instincts, that have clear objects. [citation needed] In 1927 Freud said that a drive theory was what was lacking most in psychoanalysis. He was opposed to systematics in psychology, rejecting it as a form of paranoia, and instead classified drives with dichotomies like Eros/Thanatos drives, the drives toward Life and Death, respectively, and sexual/ego drives. Freudââ¬â¢s Civilization and Its Discontents was published in Germany in 1930à when the rise of fascism in that country was well under way, and the warnings of a second European war were leading to opposing calls for rearmament and pacifism. Against this background, Freud wrote ââ¬Å"In face of the destructive forces unleashed, now it may be expected that the other of the two ââ¬Ëheavenly forces,ââ¬â¢ eternal Eros, will put forth his strength so as to maintain himself alongside of his equally immortal adversary.â⬠. In 1947, Hungarian psychiatrist and psychologist Leopold Szondi, aimed instead to a systematic drive theory. Szondi Drive Diagram has been described as a revolutionary addition to psychology, and as paving the way for a theoretical psychiatry and a psychoanalytical anthropology. In early attachment theory, behavioural drive reduction was proposed by Dollard and Miller (1950) as an explanation of the mechanisms behind early attachment in infants. Behavioural drive reduction theory suggests that infants are born with innate drives, such as hunger and thirst, which only the caregiver, usually the mother, can reduce. Through a process of classical conditioning, the infant learns to associate the mother with the satisfaction of reduced drive and is thus able to form a key attachment bond. However, this theory is challenged by the work done by Harlow, particularly the experiments involving the maternal separation of rhesus monkeys, which indicate that comfort possesses greater motivational value than hunger. In social psychology, drive theory was used by Robert Zajonc in 1965 as an explanation of the phenomenon of social facilitation. [8] The audience effect notes that in some cases the presence of a passive audience will facilitate the better performance of a task, while in other cases the presence of an audience will inhibit the performance of a task. Zajoncââ¬â¢s drive theory suggests that the variable determining direction of performance is whether the task is composed of a correct dominant response (that is, the task is perceived as being subjectively easy to the individual) or an incorrect dominant response (perceived as being subjectively difficult). In the presence of a passive audience, an individual is in a heightened stateà of arousal. Increased arousal, or stress, causes the individual to enact behaviours that form dominant responses, since an individualââ¬â¢s dominant response is the most likely response, given the skills which are available. If the dominant response is correct, then social presence enhances performance of the task. However, if the dominant response is incorrect, social presence produces an impaired performance. Corroborative evidence Such behaviour was first noticed by Triplett (1898) while observing the cyclists who were racing together versus cyclists who were racing alone. It was found that the mere presence of other cyclists produced greater performance. A similar effect was observed by Chen (1937) in ants building colonies. However, it was not until Zajonc investigated this behaviour in the 1960s that any empirical explanation for the audience effect was pursued. Zajoncââ¬â¢s drive theory is based on an experiment à involving the investigation of the effect of social facilitation in cockroaches. Zajonc devised a study in which individual cockroaches were released into a tube, at the end of which there was a light. In the presence of other cockroaches as spectators, cockroaches were observed to achieve a significantly faster time in reaching the light than those in the control, no-spectator group. However, when cockroaches in the same conditions were given a maze to negotiate, performance was impaired in the spectator condition, demonstrating that incorrect dominant responses in the presence of an audience impair performance. Evaluation apprehension Cottrellââ¬â¢s Evaluation Apprehension model later refined this theory to include yet another variable in the mechanisms of social facilitation. He suggested that the correctness of dominant responses only plays a role in social facilitation when there is an expectation of social reward or punishment based on performance. His study differs in design from Zajoncââ¬â¢s as heà introduced a separate condition in which participants were given tasks to perform in the presence of an audience that was blindfolded, and thus unable to evaluate the participantââ¬â¢s performance. It was found that no social facilitation effect occurred, and hence the anticipation of performance evaluation must play a role in social facilitation. Evaluation apprehension, however, is only key in human social facilitation and not observed in animals. 1.

The development of the novel in the 20th century - 1416 Words
4. The novel from 1881 to 1914 Over the eighteen eighties there was a split in fiction. The first indication towards it was Henry James essay The Art of Fiction (1884), which referred to the novelists calling as a Sacred office. Besides, there appeared a stratification of fiction due to primary education for all. Parallel to this, novelists saw themselves apart from the public, as dedicated men. This new modern conception involved dignity and a sense of glory. Another change was from the three-volume novel to the one volume one. Together with the demands of the new publics, this shortening divided the Victorian novel into the categories of fiction we know today. The key name in the eighties is Henry James, who strove to give theâ⬠¦show more contentâ⬠¦During the period between wars we find the Jazz Age. Then, prose fiction becomes associated with simple plots, utopian worlds and literature of disillusionment. Aldous Huxleys dystopia Brave New World illustrates how worries moved beyond their time and address ed the dangers of a technologically engineered future. An extreme example of disillusionment literature is George Orwells works, where a deception with Communism and Socialism ideals is depicted. The most relevant examples are Homage to Catalonia (1938), Animal Farm (1945) and Nineteen Eighty four (1949). 4.3. Post-War and Post-Modern Literatures and the Neo-Gothic After World War II, there are many names that are important to quote. An example is Elizabeth Bowen. She has been associated with V.Woolf since she explored the inner emotional life, as in The Hotel (1927). After the fifties, Britain lost its overseas Empire steadily but gained a new cultural diversity.That way, Britain started building itself in a culturally, socially and economically different reality. This also had its impact on literature. The new novelists of the fifties include Samuel Becketts experimental narrative, D.H. Lawrence, Lawrence Durrell, William Golding, Angus Wilson, Iris Murdoch and Muriel Spark. During the 1960s and the 1970s a new morality, already sensed in Larkins poem Annus Mirabilis (1963), appeared. This led to female and male reformulations in fiction.

Pro Life Vs. Pro Choice - 2608 Words
Medical Ethics October 28th, 15 UTEID: psp593 Pro-Life v. Pro-Choice The word abortion can be defined as a spontaneous expulsion of a human fetus during the first 12 weeks of gestation. The debate on abortion has been widely contemplated for centuries. Mainly focusing on whether or not it is morally acceptable for a woman to decide if she can terminate the pregnancy. The act of abortion only justifies that a woman should have the right to exercise her moral ethics with her best interest in mind. One of the most important cases that caught the eyes of many American people was Roe v. Wade. This particular case set the stage for women with their fight for feminism and their legal rights about being able to have options once they realize that they are pregnant, as well as having their personal privacy. The other aspect of this controversial topic is if someone is pro-life or pro-choice. Typically when a woman decides to proceed with the abortion, they progress with what they believe is the best intention for the child and for themselves. Both sides have v ery legitimate reasons as to why one could be better than the other, but in the end, it is up to the woman in hopes that she does what is in the best interest of herself, as well as the child she is carrying.

Essay An Ethnic History of Europe Since 1945 - 1311 Words
An Ethnic History of Europe Since 1945 Ethnicity, the rise of nationalism, the formation of new nation-states in the aftermath of the collapse of the Soviet Union, Yugoslavia and the peaceful split of Czechoslovakia have become central topics for politics and scholarship in the 1990s. Studies on ethnic conflict, nation building, and particular ethnic and minority groups in Europe abounded throughout the last decade. However, a cohesive book that provides a systematic and general picture of minority existence so far has been missing. Panikos Panayis An Ethnic History of Europe since 1945 (published in New York, 2000) tries to fill this gap for the post-war period. As the author correctly states, so far: no single author hasâ⬠¦show more contentâ⬠¦The third section centering on the authors definition of ethnicity discusses the politicization of cultural differences underlying his definition of ethnicity. The last section is dedicated to the role of the state in recognition of minority existence of minorities, and bri efly describes the role of modern media in their inclusion or exclusion. The authors approach, including indigenous as well as migrant minorities, provides for a challenging intellectual comparison leaving the reader with the question of what the merits, but also the limits, of comparison are. The binding element offered by Panayi is ethnicity that sets dispersed, localized, or immigrant minorities (the three categories he uses) apart from majorities in a world of nation-states. Thus, at the outset of the book one expects to learn where the author places himself within the camps of scholars who have passionately argued from the mid-1980s on about the essence of ethnicity and nationhood. The reader is surprised from the outset that Panayi does not bother with contextualizing his concept of ethnic groups and nations within these debates. Instead we learn that ethnicity, nation, nationalism, nation state and minority each [...] have a precise meaning which have become confused by [...] over-use in the media and social science discourse (p. 3-4).

So, weââ¬â¢re solving for the molar mass just like the problem on the most recent exam involving an unknown solute. ) ? Tf =Kfmsolute msolute = ? Tf/Kf Our ? Tf = 78. 2à °C ââ¬â 76. 7à °C = 1. 5à °C. Letââ¬â¢s use the ââ¬Å"realâ⬠Kf instead of the one we calculated so weââ¬â¢ll get a better answerâ⬠¦ msolute = 1. 5à °C/7. 45 Kà ·kg/mol = 0. 201 mol/kg (molal) Now, we know the molality, and we know the number of kilograms of solvent (0. 010 kg of naphthalene)ââ¬âletââ¬â¢s find the number of moles of sulfur present. oles of sulfur = molality x kg of solvent = 0. 201 m x 0. 010 kg = 0. 00201 moles sulfur Now, divide the mass of sulfur we took by this number of moles to get the molar mass of sulfurâ⬠¦ 0. 500 g sulfur/0. 00201 moles sulfur = 248. 8 g/mol This is the molar mass of elemental sulfurâ⬠¦ divide it by the atomic mass of sulfur (32. 07 g/mol) to find out how many sulfur atoms there are in a sulfur molecule. We get 7. 76 ? 8 atomsâ⬠¦ isnââ¬â¢t it cool how you can get the right answer when you make up your own data? ðŸËâ° Back to General Chemistry Home Page Back to General Chemistry Syllabus How to cite Chemistry Lab, Essay examples Chemistry Lab Free Essays The pKa of an Unknown Acid-Base Indicator By: Josephine Hong Lab Instructor: Yue Zhang Due: April 5, 2013 Submitted: April 5, 2013 Abstract: In this lab, the pKa of the unknown indicator of expression was determined both qualitatively and quantitatively. To verify our procedures, the experiment was tested using a known indicator, bromocresol green. Qualitatively, we used the color change of the solution with indicator to obtain the pKa value solely using a pH meter. We will write a custom essay sample on Chemistry Lab or any similar topic only for you Order Now Quantitatively, we used a pH meter and the spectrophotometer with varying concentrations of the acid and base. The maximum wavelengths of absorbance used to quantify the dissociated and undissociated forms of the bromocresol green were 440 nm (yellow, undissociated) and 616 nm (blue dissociated). For the unknown indicator, the wavelengths were 505. 96 nm (red, undissociated) and 601. 66 nm (blue, dissociated). For bromocresol green, the experimentally obtained pKa value measured qualitatively was 4. 04. Quantitatively, the pKa came out to be 4. 16. The percentage error (10. 47%) obtained was within reasonable range, allowing the same procedures to be used to determine the pKa value of the unknown indicator, Indicator of Freedom. Indicator was Freedom was found to have a pKa value of 5. 32 qualitatively essay writer typer. On the other hand, the quantitative pKa was measure to be 4. 265. Introduction: This lab applies the concept of an indicator dye, which is principally a weak acid that changes colors when reacting with the amount of hydronium ion in a solution. Thus, the qualitative part of the lab assumes that at the point where the solution changes color into an intermediate shade of the two, the concentrations of [HIn] and [In-] is approximately equal. Using the Henderson-Hasselbalch equation for them: he pH equals pKa when the ratio between the indicator and its conjugate base is 1. Subsequently, the quantitative portion of the lab deals with the relationship between absorbance and concentration: A1(? )A2(? )= c1c2 Thus, a certain absorbance of a solution can provide the concentration of the indicator and its conjugate base when taking into consideration the maximum wavelength of the two colors. Experim ental Section: To reduce the volumes of acid and base needed and the amount of time to complete the lab, the stock solutions of strong acid and base were diluted to at least one-fourth their starting amount. Thus, 60 mL of deionized water was added to both stock solutions of 20 mL HCl and NaOH to create 2 new 80 mL diluted solutions. Part 1: Finding pKa Qualitatively 25 mL solution of the diluted NaOH with 3 drops of indicator was titrated against the diluted HCl drop wise until a color change occurred. To determine the pKa of the indicators, the pH of the solutions were taken with a pH meter when there was a color change. Determining the color of bromocresol green to be yellow when acidic and blue when basic, the point of color change to measure pH was when the solution turned green. Likewise, the indicator of Freedom was red when acidic and blue when basic, which established the point of color change to be purple. These steps were performed three times for both the known and unknown indicators to find an average pKa value. Part 2: Finding pKa Quantitatively For the quantitative determination of pKa, multiple solutions of varying acid/ base concentration were prepared with 3 drops of indicator. Despite the varying concentrations of each solution, the total volume stayed constant at 20 mL. Before anything, the wavelengths of maximum absorbance were determined first by using solutions of pure acid and base with three drops of indicator. For each solution, the pH was measured before placing them in cuvettes to measure their absorbance values using the spectrophotometer. These steps were performed for both the known and unknown indicator.

The unreliability of visual observation of the slight color change in solution could have dramatically affected the results. Because the experimentally determined pKa was less than the actual pKa for both cases, strong enough color change were probably not observed. Since the titration was performed roughly using drops, the drops could have added more acid than needed, resulting in a smaller pKa.. Quantitatively, the pKa can be determined by plotting the data, with absorbance as a function of pH. There will be two separate lines, one for each wavelength of the two colors. The intersection of these two lines will indicate the point at which the pH should be equal to the pKa. This works because at the intersection point: pH=pKa+logIn-HIn It is known that A1A2= c1c2. Since A1= A2 at the intersection point of the graph, then 1= c1c2= In-HIn. Thus,pH=pKa+log1 pH=pKa at the intersection of both curves The procedure for determination of bromocresol green pKa appeared to have worked, because the percent error was roughly around 10%. Although slightly high, these errors are unpreventable. For example, cuvettes with smudges on the sides would have increased the absorbance readings of the solutions. Moreover, the maximum wavelength is crucial because it is used as a standard to know where to record the absorbance levels of the other solutions. This is because it is where the maximum absorbance occurs for the particular color produced by the solution is. It is important to measure the absorbance levels at these standardized wavelengths to keep the data consistent and to have the ability to compare the absorbance levels of two solutions without the need to calibrate or adjust the readings. Finally, a limited number of data points when determining the pH graphically could have also added to the error in this experiment. How to cite Chemistry Lab, Papers

Risk Management Plan of SFSU Free Samples â⬠MyAssignmenthelp.com
Question: Discuss about the Risk Management Plan of SFSU. Answer: Introduction Risk administration is a technique to identify the probable opportunity and risk[1]. Thereafter the list is segregated as per the positions obtained during analysis. Subsequently the mitigation or response plan is developed on the basis of positions obtained. The data obtained are required to be dealt with the opportunity and threat and plan in like way with the objective that it doesn't let influence any of the three limitations of the project. Background of case study SFSU (Silicon Forest State University) has numerous data framework related exercises which are being regulated by the OIT (Office of Information Technology) division. The clients at back end of OIT used 'Request Tracker' for passing on and following the ticketing system in light of UNIX, while the clients at front end were using Remedy structure for making and following ticketing system which is being utilized for observing and following the bugs. For any kind of interest to clients of back end, the clients of front end need to physically type the issue to 'Request Tracker'. However, now the workplace changed the product being utilized by the clients of front end to 'Request Tracker' and gave the task to Ron to lead the venture with the help of Harry, however both of them need to report to two different bosses. Risk Management Plan Opportunity and dangers in any assignment are coordinated on the preface of the techniques defined in the risk management. The exercises which link into the masterminding of threat association design are recognized, analyzed and positioned accordingly[2]. The opportunity and dangers can be of many sorts, and fit for affecting cost, plan and quality, particular, really definitive and so forth. An entire reason for the risk design is to set the activity and make ourselves ready for all the perceived dangers especially at a range by saying rank low, medium or 'high'. There are particular sorts of dangers facilitating procedures or steps which should be taken in the wake of situating all the perceived opportunities and threats. There can be many activity intends to moderate the hazard like exchanging it, imparting it to any external party, staying away from it absolutely or tolerating. Risk Identification (27th August 2017) RISK 1. By Pike. There is threat of having cost overrun (30th August 2017) RISK 2. By Ron. There is threat of having communication gap due to same organizational level of myself and Harry (1st September 2017) RISK 3. By Harry. There is threat of having time overrun due to extra time consumed during information gathering stage Risk Analysis RISK No. By Description Probability Impact 1 Pike There is threat of having cost overrun High High 2 Ron There is threat of having communication gap due to same organizational level of myself and Harry Medium High 3 Harry There is threat of having time overrun due to extra time consumed during information gathering stage Medium Medium Risk response plan[3] Risk 1: cash flow need to be monitored closely. There can be other plan of keeping the management reserves if possible. Since the budget allocated for the year is very low. Risk 2: frequent meeting rather than communicating through mails is the only way out so that the team can meet physically and share each others issue openly. Risk 3: time schedule need to be monitored closely to avoid any delay, else the extra time consumed for gathering the information can cause the overall delay of the project and the communication gap can increase. Monitoring and Controlling Risk This stage of risk administration is required for the proper management of the risks throughout the project life cycle[4]. The risks are very dynamic in nature and can change its ranking frequently as or the environmental conditions. So the risk register need to be reviewed in every stages of the project for proper monitoring. Moreover the new risks identification should not be stopped and the identified risks need to be again analyzed as above and ranking and its mitigation and response plan need to be developed. Evaluation / Justification Finally it can be justified that the result obtained by the processes of identification and analysis of the risks, the obtained result are the real cause of tension for Ron. There is always a chance of cost and time overrun because of communication gap. Also the steps need to be continued throughout the project life cycle to identify any more threats[5]. Conclusion So now it can be finished up at long last that the undertaking brought about by OIT should be followed categorically like cost, time and communication and none of the issues can be overlooked. Else there can be cost and time overrun. So it should be Rons responsibility to take care of the constraints and discuss these issues in every meeting to infiltrate the issues to all stakeholders.

Compass and The Torch Essay Example
Compass and The Torch Essay When growing up children fight to be accepted and to be heard by their parents. In society most parents are constantly on the run and they do not take the time to enjoy spending time with their loved ones. These children try to get attention from their parents, but if their parents do not hear them, then they will feel like they have failed, but because they love their parents they accept it, and do not question their parents behavior. At the same time parents might also try to reach their children, but they get lost and therefore he relationship between the child and the parent can be damaged, because neither Of the parts feel like they get heard. Accepting and the fear Of losing are two of the main themes in the short story Compass and Torch, where a father takes his son with him on a camping trip, where the son tries to talk to his father, but his father does not pay attention and his father tries to forget his anxiety to lose his son. Compass and Torch was written by Elizabeth Beanies, an English writer and was published in 2003. The short story starts in medias rest and the story is built up chronological tit a few flashbacks between the camping trip and at his mothers house. The story is set at two different locations, one location at the boys mother and her boyfriends house and the second location on the camping trip up in the mountains. The short story is told by a third person narrator and is attached to the boy, therefore the story is told from his point of view. The boy adores his father. His father on the other hand, does not seem to be very interested and he does not show any interest when his son shows him his torch or talks to him. Before going on the camping trip with his father, the boy hears his mother talks badly about the father, and the relationship between the boy and his father can be damaged since the boy lives at his mother who does not speak nice about the father. The father is so afraid of losing his son that he forgets to pay attention when his son speaks to him.

The boy accepts the fact that his father does not pay attention to him, and the ether is not aware of his sons desperation. The boy is eightieth old. He is a flat-round person, since we do not hear much about his looks but what is on his mind instead. He is also a static character, because he does not grow as a person he sticks to whom he was when the story began. He lives with his mother and her boyfriend Jim. His mother does not trust her ex-husband, and she feels the need for telling her husband that they cannot go camping near the edge. Even though Jim is very nice to him, he is still not his own father, and therefore does the boy treat him tit caution. The boy is afraid of opening up for other people since the boy adores his father and he watches his every move. But on the other hand he calls him the man, so it is almost like he forgot his father. When he tries to show his father his torch, his father looks away and the boy does not get upset: Ifs K, the boy decides, that his dad hasnt looked at the torch, hasnt studied it like Jim. (Page 8, line 49-50), and when his father almost cancel their camping trip, he is full of fear even though he had a brief moment where he did not want to go. He seems to be very sensitive but at the same time he tries to avoid confrontation with both of his parents: his father, when he does not listen to him or pay him half attention and when he overhears a conversation between the mother and Jim talking bad about his father. The torch symbolizes the connection between the boy and his father. Its better to have it for a proper purpose, to put it away, to carry it carelessly but with meaning, as a warrior might carry his sword. A torch is for lighting when the time comes, for lighting up the expedition of father and son. (Page 8, line 50-53). It is what keeps them from fading apart, but it can also symbolizes the fathers anxiety to lose his son; The man gently takes away the torch (Page 11, line 166). The son who is so eager to speak and to be acknowledged by his father, and the father who is very afraid of losing his only son one year on from the separation, and therefore he only listen to half of the things that his son says. They are camping up a mountain and the mountain, which symbolizes the foundation of their relationship, and it is as firm as a rock. The main theme in the short story is the fear of not getting acknowledged is en of the struggles that the little boy fights with. The father on the other hand struggles with the fear of losing his son, and he becomes so desperate that he forgets his son and loses him: For years to come, though, in his dreams the boy will see their wild fringed eyes and feel the deep thudding of their hooves. (Page 11, line 169-170). The story shows how important it is to live in the present and communication is one of the most important tools to make a family work. If communication works in the family it is more likely to believe that acknowledging and accepting one another is easier.
