Mid-term history exam - Essay Example The fundamental changes happening in the natural sciences, in particular, generated a new image of the universe that emphasized the supernatural less (Westfall). This proved crucial for a gradual change in society and an increasingly deemphasized role of religion in our modern society. An example of such a change in ideas was the replacement of the Earth with the Sun as the center of the universe, which contradicted Aristotelian and Christian scientific doctrines. The Age of Enlightenment, like the scientific revolution, was the source of dramatic change in European society, centered primarily in the 18th century. The movement changed the way people thought about the world, insofar as it created a shift to a so-called â€Å"rational† view of the universe. Instead of allowing the â€Å"sacred circle†, which refers to the hereditary aristocracy and leaders of the church, to continue, the Enlightenment allowed individuals and thought to break through the value systems of t he past (Gay). Among these new values were those of freedom, democracy, and reason as the goals and reason for society. In particular, the idea that rationality ought to be applied to every problem left a significant impact on many areas of society. These kinds of fundamental shifts in thinking are what made scientific advancements, like those seen during the scientific revolution, possible in the first place. Scholars contrast the Age of Enlightenment with the Middle Ages, which is nearly universally held to be a time of scientific and rational suppression (Lindberg). In terms of science during the Middle Ages, most of the inquiry was based around the texts of ancient scholars like Avicenna and Aristotle. Scientific practices from these ancient sources were marginally empirical and often depended on philosophical systems about how the universe was structured, as opposed to utilizing mathematical functions or previously acquired empirical knowledge to make new hypotheses. As a resul t, the science from the Middle Ages was lacking in productivity or practical applications to the problems of society. The scientific revolution, which sought the practical aspect of science, and the Enlightenment, which sought the application of reason to life’s problems, changed this emphasis. However, the Middle Ages did leave a lasting impact on the practice of science, through to the modern period, which is the university system where science was centralized and practiced openly (Lindberg). Even if the science practiced in these universities was strongly influenced by the religious doctrines that governed the universities, the practice of locating the practice of that science into one location was a lasting influence. The Enlightenment has directly affected modernity in a number of ways, including but not limited to the political revolutions of the late 18th century in America and France. Although the French revolution eventually became an exercise in irrationality and hy steria, the ideas behind it and the American revolution were born out of a changing value structure in society. No longer were the â€Å"sacred circle† that highest value and hierarchically placed at the top of society; rather, it was ideas and reason placed at the top of this structure. Governing a society with ideas led to the concept of the â€Å"rule of law†

Research Design Essay Example | Topics and Well Written Essays - 500 words

Research Design - Essay Example The researcher considers the impact of confounding variables while attempting to establish the effect of the treatments by measuring changes in the dependent variable. Central to this design is random assignment. In a sense, this is the only design that can truly establish to greater degree than other designs the cause-and-effect relationship between and among variables. This is done through statistical methodologies to measure if the changes observed are significant enough to warrant causality. An example of these statistical tools is the ANOVA. The quasi-experiment, as opposed to the true experiment, does not employ random assignment. Instead, the subjects are chosen out of convenience to be part of a particular group. It can be said then that somehow the researcher may be measuring the effects of confounding variables rather than the target variable. Moreover, the reason for including the subjects in a particular group can in itself serve as a confounding variable. However, this design also has a means of comparing groups. It also uses statistical tools to account for a cause-and-effect relationship. The single-case design relies solely on an individual subject or a group of subjects to test and compare the effects of treatments. Central to this design is the baseline measure from which the researcher compares the posttest measurements.

Heat transfer by convection Essay Example | Topics and Well Written Essays - 1250 words

Heat transfer by convection - Essay Example A square cavity was used whereby its bottom and top walls were insulated. One of the side walls was presumed cold while the other side hot. Alumina/water nanofluid was used as the working fluid. It was concluded that using different thermophysical models might lead to opposite trend estimations for Nusselt number especially in high solid volume fractions. Effects of inclination angle (between 00 and 1200) of a square cavity filled with Cu/water nanofluid on heat transfer (Abu-Nada and Oztop). The boundary conditions of both experiments were similar. Different water based nanofluids containing Cu, Ag, CuO, Al2O3 and TiO2 nanoparticles were placed in a cavity with volume fraction up to 20%. One side of the walls was heated using heater mounted on the wall; cavity angle varied between 00 and 900 (Ogut). Increased concentration increases heat transfer rate. Average Nusselt number has a high sensitivity to viscosity compared to the thermal conductivity at high Rayleigh numbers; suitable v iscosity model should be selected (SAEED ZEINALI HERIS, Masoumeh Borhani Pour, Omid Mahian, Somchai Wongwises, 2014). Flow of Cu, Al2O3, and TiO2 nanoparticles is suspended in water in a cavity where top and bottom walls are insulated; right wall is kept cold while the left wall is subjected to the periodic heat flux. Use of Cu and TiO2 with volume fractions up to 20% leads to maximum and minimum heat removal from heat source respectively (Ghasemi and Aminossadati). Flow of Cu/water nanofluid (volume fractions up to 5%) in a square cavity and the bottom subjected to constant heat flux while cooling is conducted by entering a nanofluid flow from the left wall and exiting from the right wall (Shahi et al). It was concluded that an increase in the volume fraction increased the average Nusselt number in the cavity. Lin and Voili simulated the effects of particles size on natural convection flow of Al2O3/water nanofluid with volume fraction up to 5% in square cavity

Intermediate Econometrics - Coursework Example Let and denote their unadjusted counterparts. Then; The answer is FALSE; in loglinear regression analysis is used to describe the pattern of data in a contingency table. A model is constructed to predict the natural log of the frequency of each cell in the contingency table. For a 2x2 table, that means the model is . So we can always say, as a simple function, that the coefficient represents an increase in the log of predicted counts. If , for instance, we could say that this model shows that factor increases the predicted log count by 2 (all other factors held constant). The answer is TRUE; all the three tests (Wald test, Lagrange Multiplier, Likelihood ratio test) address the same basic question, which is, does constraining parameters to zero (i.e. leaving out the predictor variables) reduce the fit of the model? The null hypothesis for all three tests is that the smaller model is the "true" model, a large test statistics indicate that the null hypothesis is false. The only difference between the tests is how they go about answering that question. The graph below explains more on the relationship; The graph below illustrates what each of the three tests does. Along the (labelled ) are possible values of the parameter . Along the are the values of the log likelihood corresponding to those values of  a. The test compares the log likelihoods of a model with values of the parameter constrained to some value to a model where  Ã‚  is freely estimated. It does this by comparing the height of the likelihoods for the two models to see if the difference is statistically significant (having in mind, higher values of the likelihood indicate better fit). In the figure above, this corresponds to the vertical distance between the two dotted lines. In contrast, the Wald test compares the parameter estimate  Ã‚  to  ; where  Ã‚  is the value of  Ã‚  under the null hypothesis, which generally states that  . If  Ã‚  is significantly different

Thinking Realities of Yesterday, Today, and Tomorrow Assignment

Thinking Realities of Yesterday, Today, and Tomorrow - Assignment Example (Singleton, 2010, p. 143) There has been a considerable shift in the perception of a â€Å"good nurse† over the years. Traditionally, literature concerning nursing ethics indicates that the merits of the nurse included such qualities like being respectful towards authority (especially of medicine), being loyal to duty, being careful, being calm, gentle and clean. Sympathy, concern or any kind of emotional attachment with a patient was discouraged and was considered to be a weakness in the character of the nurse. The early literature also mentions unwillingness to ‘report’ another nurse or defy any unsafe practice. Other essential qualities budding from the ethics literature were obedience, tolerance, serenity, modesty, humility etc. (Begley, 2010, p. p. 527-531)In the past the training of nurses in matters of ethics often focused on things like how to dress and to show respect (etiquette) rather than act upon the moral perceptions of practice (ethics). However, this does not indicate that all nurses were meek and timid and were not able to think for themselves. But in actuality, the culture was such that it did not encourage assertiveness or support challenges to the authorities. (Meehan, 2012, p. 2905) The nursing practitioner today is expected to question and team up with other professionals instead of just obeying instructions of the superiors. Patients’ well being is the first priority and today nurses are accountable for their actions and are given the responsibility to guard the patients from the mistakes and carelessness of others. Today the nurses are expected to have a strong knowledge of their work and they are expected to be sufficiently confident to confront doubtful practice. Based on right knowledge and information, today’s nurse should report any method or behavior or action practiced that is unethical, unsafe, illegal or incompetent in nature. Thus, modern codes of ethics

Response Sheet Essay Example | Topics and Well Written Essays - 250 words

Response Sheet - Essay Example Although the main intention of the author was to see the full moon rise, he was attracted so much by the scenic beauty of Navajo that he could not believe what he was experiencing was real. The author reveals his excitement by stating that â€Å"all Navajo dwellings face east†. He is so much swayed by the nearby surroundings that he also camped facing the East. When he saw a Navajo girl herding a flock of sheep, he could not resist expressing his feelings towards the dress and ornaments that she wore. He also finds a woolly dog to be different than others under the influence of the moonlit night. Indicating his state as almpst hypothised by the opitate environment, the author himself is unsure whether the girl or the dog that he saw were an illusion or he was really experiencing something different. It was so strong that he compares himself with the wizard of Stonehenge waiting eagerly to see the full moon rise, tempted with the charm and the scenic beauty of the location, the author is filled with thrill and excitement. Illustratively, he could not restrict himself questionning: â€Å"Has the Navajo medicine men contrived this for our benefit?† (Young

Bill of Rights Coursework Example | Topics and Well Written Essays - 1000 words

Bill of Rights - Coursework Example There is also the danger that individual rights of speech and assembly and redressal of grievances can be used by canny citizens to trouble others, for example, the encouragement of an intrusive media, and unnecessary litigation in courts of law. While such a clause may have been necessary for the security of the individual in pioneering days (this is also debatable, as these arms were often trained on the original inhabitants-the Red Indians-who have today been unjustly herded into settlements, in their own land) now, it has led to lawlessness: shooting sprees in malls and schools, for instance. Fourth: This amendment was enacted to ensure privacy as well as protection against unlawful or malicious action against citizens by the agents of the state, which may also be seen as the benefit accruing to a citizen from it. There are circumstances when exceptions to the amendment become justified for the sake of the security of the state and citizenry. These exceptions are, for example, detainment and search of a person who behaves in a suspicious manner, or searching of persons in sensitive areas like airports/ border areas. As a matter of fact, the 9/11 incident possibly happened because of adhering strictly to the spirit of this amendment, whereby travellers at airports were not checked thoroughly. The advantage to the citizen was that it was fair to him. ... Fifth: This amendment was enacted to ensure fair treatment of the individual who is charged with a crime. The advantage to the citizen was that it was fair to him. Even a citizen charged for a crime has a right to be fairly treated, especially in the event that he is wrongly charged. The disadvantage is that a canny lawyer could use the amendment to subvert the justice system. Eg, in the OJ Simpson case, the criminal case against Simpson absolved him of the murder of his wife, Nicole, while civil proceedings held him culpable! Sixth: The amendment like the fifth was enacted to prevent arbitrary treatment of an accused, and to ensure justice for all. This is an excellent provision governing the justice system, to safeguard a citizen's rights, and to ensure speedy disposal of cases. Any negative feature of this could come about not because of the amendment per se, but because of the way the system could be perverted by those seeking to take advantage of it. (eg perverting the law by canny lawyers to adhere to the letter of it minus the spirit.) Seventh: England had courts of common law, which gave legal (monetary) relief, and courts for equity which decided non-monetarily (an injunction, for instance) This amendment sought to combine both the jurisdictions. The advantage or disadvantage of the amendment depends totally on the complications involved in a case-especially where both equity and common law elements are involved. Complexity in the actual application of the amendment is inevitable, not because of anything contained within it, but because judicial disaputes are essentially complicated. Eighth: This amendment was enacted to ensure humane treatment of a crimininal, and herein lay its strong point. But a habitual
