Historical inaccuracies in Ridley Scott’s film `Gladiator Essay

In recent years the emergence of filmmakers who expressed interest in adapting historical events as wide-screen presentations has revitalized public interest on historical events. But the usual problem is that the general public’s view usually gets distorted due to contemporary filmmakers’ nasty habit of utilizing their artistic license to its full extent More often than not, adaptations of historical events like Ridley Scott’s Gladiator offers a glimpse of early civilizations but neglects the aspect of historical accuracy which in turn cannibalizes scholarly efforts to reconcile public interest in the actual historical events. The glitz and glamour of commercial cinema is in large part responsible for the historical inaccuracies of Ridley Scott’s Gladiator. Martin Winkler (17) suggests that the reason behind a historical film’s departure from its origins is that the fiction which causes the inaccuracy is what sparks viewer interest in the first place. In accordance to Winkler’s theory, the elements incorporated in Gladiator contributes to the film’s historical infidelity; its principal characters, chronology, production design, and supposed intent of exhibiting the authentic life and culture of Imperial Rome, has been diluted by the filmmakers’ aesthetics. As per what the film entails, the structure of the Gladiator’s narrative appears to be drastically shortened. Commodus’ reign was marked by numerous assassination plots, including a scheme that involved her own sister Lucilla, all accounts of murdering the treacherous emperor have neither been established nor even mentioned in the film. Historical accounts further suggest that Commodus’ reign ended 13 years later upon his assassination (Boatwright, Gargola, & Talbert 405-406), the film, on the other hand, although the time frame of events were never actually mentioned or given much attention, it illustrated that Commodus reigned no more than two years (Ward 33). The film also depicts that Emperor Commodus died in a gladiatorial duel with Maximus, obviously in a coliseum, with the intent of bringing back democracy to Rome and re-establishing the country as a republic. While the 73rd book of Cassius Dio’s eye-witness account of Roman History imparts that a wrestler who popularly went by the name Narcissus choked the life out of Commodus, and the incident happened in the emperor’s bath. The film’s characters also share an extent of inaccuracy with the actual historical personalities from which they are derived from. Evidently, from appearance to characteristics, the film’s Commodus did not reflect the Roman Emperor whom history recognized. Primarily, Commodus’, in the film, is bequeathed as a dark hared man in his mid 20s who fights with his right hand and has an underdeveloped physique (Ward 33). While the historical Emperor Commodus was and 18-year old blonde with a well developed physique and fought with his left hand (Kyle 224-227). Likewise, the actual description of Commodus’ personal traits was inconsistent with the film as the historical Commodus was notorious for his corruption, violence, and lust for blood. The film shows the aforementioned characteristics through Commodus’ fixations on sports such as beast-hunting, chariot-racing, and gladiator combat as well as his claims to have won over 1,000 battles (Ward 32). However, Scott’s incarnation contradicts the true nature of the roman emperor as he is characterized by his guiltless lack of emotion and compassion, ruthlessness, cowardice, and mental instability (Hekster 53-56). Contrary to the film’s illustration that Lucilla had an 8-year old son named Lucius Verus, Allan M. Ward’s Gladiator in Historical Perspective entails that, historically, the son who went by the name Lucius Verus died during infancy. Also, Lucilla gave birth to three children during her marriage with Lucius Verus Marcus and only one of the three children survived and grew up, an unidentified daughter who became part of the assassination scheme against Commodus. Lucilla, however, bore a son but she did so in her marriage, with Tiberius Claudius Pompeianus, and the boy’s name was Aurelius Commodus Pompeianus who was 6-years old during the time of the film’s events. Similarly, the reason behind the strained father-daughter relationship between Lucilla and Marcus was the latter’s arrangements of a second marriage for his widowed daughter. Apart from the disrespecting reality that the second marriage occurred only 9 or ten moths after Verus’ demisae as well as the tremendous gap between the couple’s ages (Lucilla was 19 while Claudius Pompeianus was approximately in his 50s), Lucilla also felt undignified by the fact that her new spouse came from a family of provincial equestrians in Antioch, Syria (Ward 33-34). However, the film did not took such event into account leaving the reason behind the cold relationships between the former emperor and former Augusta vague (Ward 33-34). The film’s central character Maximus Decimus Meridius, is a fictional character based on the archetypes of able-bodied men from the far reaches of the empire’s jurisdiction who served as the materialization of Marcus Aurelius’ persisting idea of using men beneficial to the imperial cause (Ward 38). To a similar extent, Maximus’s character is attributed to two recognizable Roman political and military personalities, Marcus Nonius Macrinus who was one of Marcus Aurelius’ closest friends and Tiberius Claudius Pompeianus who was partly responsible for the Roman triumph over Marcomannic War in the film’s beginning (Popham). George Depue Hadzsits (70) suggests that a film such as Gladiator is more likely to revive interest in the subject of history considering that scholarly efforts simply produce fragments of history which does not fulfil the human yearning for knowledge. Hadzsits furthers that despite such visual spectacles’ temporal didactic value and lack of attention on the angle of accuracy, at least the interest for the subject matter is roused (Hadzsits 71). The problem with Gladiator, conversely, is that its revival of interest in Roman History, or ancient world history for that matter, seems to delineate the supposed dissemination of ancient Roman culture and alters it with norms that the filmmaker deems right. In terms of production design, the armour and weaponry worn and yielded by the gladiators appear to have a medieval design rather than Roman. Allan Ward (39) writes that gladiators had already been placed under categories like eques or horseman, provocator which is believed to be the term for challenger, murmillo or what is considered as water combatants, hoplomachus or gladiators who wield heavy weaponry, retiarius the net fighters, and secutors or contraretriarius otherwise characterized as the light armed fighters. However, Ward (39) argues that the film does not seem to highlight the distinctions between gladiators as all of the competitors generally wore the same armour with little differences in weapons of choice. Ward furthers that each fighter category comes with a different set of weapons and armour as well as a different style in combat. The matches between two gladiators are dependent of their category and fighting abilities, a secutor, for instance was often matched with a retriarius, perhaps due to the resemblance in the nature of their weapons and battle skills. Moreover, gladiators within a similar category were not paired to pit against each other, with the exception of the horsemen and the challengers. As mentioned earlier, one of the premises tied with Gladiator is the tendency to rouse interest on the life and culture of ancient Rome, but in this context the film is also inaccurate. James R. Keller (88) implicates that Gladiator imposes the American devotion to the principles of democracy. Initially, the final confrontation between Maximus and Commodus should incite the cultural importance of gladiatorial combat in ancient Rome, however, the re-arranged plot of the film that caused the conflict between the former general and the treacherous emperor to fail in its attempt to do so. The conflict then suggests that Maximus represents every working class, freedom loving American while Commodus serves as the embodiment of the corrupt, insensitive, and inconsiderate aristocrat (Keller 88). In its inaccurate entirety, Gladiator has proven itself to be more of a costume drama adaptation rather than a re-telling of an antiquated historical tale. Despite the filmmakers’ efforts to conduct research and seek consultation for relevant information about the film’s source, the direction remained in the production people’s perspective and not with the scholarly one as the motion picture continued with the re-arranged biographical information of the characters and the reformatted events in the lives of the characters. In addition, the film simply delivered a visual spectacle rather than a knowledgeable historical fact. Martin M. Winkler (204-205) writes that film producers and other individuals concerned with marketing cultural products habitually call on scholars to guide them in marketing historical films. This is, in large part, brought about by producers’ beliefs that scholar credibility is enough to amplify the promised prestige and revenue of their product. Scholarly prestige according to Winkler is mainly vital as a marketing strategy, but a more appropriate term seems to be deceptive advertising as investing parties and supposed artists convince the public of the accuracy of their distorted historical documentation with the aid of renowned experts

Paleolithic

Our class will be going outside to try to help us understand Paleolithic times. We will experience the world as Paleolithic people did – bringing only what we can carry, having no permanent shelters, creating our own art from the materials around us and having to figure out the best place to stay. For this activity, we will assume that you are traveling in a small family group that Is part of a larger group of 31. You can be with either two other people or work with a partner, representing the core family group. It was typical of Paleolithic times that related core family groups would join together o form a larger group.This â€Å"family† would work together to gather food and protect each other. The group was usually between 15 and 30 people, though smaller and larger groups existed. As they traveled, different family groups would meet to exchange goods that they had made and they likely shared Information about the local environment. Young people likely moved between groups in order to share expertise (a group with several artists might exchange an artist for a skilled hunter) or to meet the needs of both groups (a group with extra males may send some to another group in exchange for goods or services).Over time, the larger group size allowed for some specialized roles to develop. The majority of people in the group would supply food for everyone, giving some people free time. For instance, a religious leader, artist or expert craftsman might supply the group's spiritual or technological needs rather than hunting or parenting. Women could take on a leadership role in the group. Women who gathered plants and hunted for small animals in many cases supplied most of the food for the group. In their role as mothers, they were protected from the most dangerous tasks, such as hunting or participating In battles with enemies.Instead, these types of tasks would be left to the â€Å"extra† males (the young and unattached men who were not yet In re ligious, artistic or craftsmen roles). Your task is to imagine yourself as part of Paleolithic times and to complete the following tasks. Your teacher will check that you are done at least Number 1 and Number 2 before the end of the period: 1. Use the map you have been given to decide where you will camp and have at least one person in your core family group record your reasons in the space provided. Consider the wants and needs of your group in addition to the geography of the area n your decision. . Using the tarp, sucks, butter knife and string, create a stable shelter. It will be 3. Using the modeling clay (which we are pretending is natural clay or soft stone), carve a Paleolithic figure and place it at the door of your shelter. 4. As a group or pair, explain what you think the daily life of Paleolithic people might have been like by creating a daily timeline to explain what your family would do at your campsite between the time you woke up and the time you went to sleep. Try t o include the challenges you faced today, such as weather, teamwork, etc. In your experience.

Abusive Usage of Internet Can Destroy Society Essay

Abusive Usage of Internet Can Destroy Society - Essay Example Additionally, it has provided a convenient means of conducting business, networking and social interaction. In the midst of all these remarkable fetes, internet also poses great threats to the same society that it has benefited. Arguably, use of internet within rational realms is safe and beneficial both in short and long term. Internet usage in the workplace makes the operations quick, effective, and reliable. However, misuse of the internet in an organization ahs detrimental effects that can destroy the organization and the society (Anandarajan, 2006, p. 15-17). This paper, therefore, presents an argument on how abusive usage of internet can destroy society. Sedentary Behavior The fact that internet has made communication possible by just a click of a button poses a serious threat to the society. It is a common phenomenon to see people sitting in front of their computers the whole day and get all their needs accomplished. Whereas it is possible to meet our needs through internet us e, the same can potentially pose a great health risk to the society. Sedentary behavior has become the order of the day as the society use internet for virtually all activities. It is only a matter of time before an appreciable size of the society becomes physically inactive. Indeed, some scientists have flagged sedentary behavior as one of the causes of overweight, obesity, stress, and other related diseases. This is certainly destroying the society and the same will continue unless the society develops moderate use of the internet. Overdependence Although the internet is a relevant source of information, overdependence on the internet is arguably one of the factors that have led to a lazy society and poor quality of education. Ideally, all the information we need is in the internet and hence students and researchers have turned to the internet for the provision of this information instead of going to the libraries and other physical sources (University of Notre Dame, 2008, p.1). T his has led to immense levels of laziness since the students will only need to sit in front of a computer and do their studies. In addition, the overdependence on the internet has led to poor quality of educations as the students and researches simply rely on the internet information with no further insights to the topics in question. Hence, issues of plagiarism that negate quality are very rampant in the modern information sector. Moreover, excessive time spent on the internet can jeopardize a marriage, as the partners will have no time for marital issues (Young, 1998, p.222-224). Moral and Ethical issues The internet has clear-cut avenues to immorality and unethical behaviors. Where there are no age limitations to the access of internet in the world, the internet contains subtle and immoral information that is highly accessible to all. Contents of pornography (Erooga, 2012, p.14), drug abuse, terrorism, and other unpleasant attributes feature in the internet (Asian School of Cyber Laws, 2003, p.2). Additionally, children can become victims of sex offenders who use the internet to target children, lure them, and communicate with other sex offenders (Davidson, 2008, p.66). Students and minors misuse the internet by accessing the sites that influence them to immoral and unethical behaviors. Teens copy these behaviors thus degrading morality in the society. In addition, internet users misuse the internet by login to music sites like YouTube and downloading videos, movies, and audio music free. These acts promote music piracy and are against music copyrights and patents. Hence, they are unethical as they deny the music producers and artists their due returns. This oppression

Issues Related to GMOs Consumption Essay Example | Topics and Well Written Essays - 1500 words

Issues Related to GMOs Consumption - Essay Example The information regarding the safety of use of GM food is present in abundance. There are various publications, blog posts, journals articles and reports that shed a light on the subject. Naturally, the opinions are split in half with supporters and opponents of genetic engineering presenting their arguments and claiming their superiority. Presented below are the references for both sides of the debate. Pro-GMO sources. The Genetically Modified Foods: Harmful or Helpful? by Debora Whitman is the general and detailed overview of the current state of affairs regarding genetic engineering of foods and general reaction to it. The author presumes that genetically modified crops may represent the most robust solutions to the current food crisis. Yet, it will pose numerous challenges both scientific and ethical when developing a proper systematic approach to GMO in food. The main benefits and goals of genetic modification of crops are mentioned as well allowing the reader to develop a bette r understanding of a broader scope of the event. Whitman concludes that genetically modified foods do represent a solution to many problems and that their safety should be evaluated in each case and not by the merits of general assumptions.   The report The Safety of Genetically Modified Foods Produced through Biotechnology delivered by the Society of Toxicology and published in the Toxicological Science journal gradually explains academic standards and procedures used to examine genetically modified foods.

IPad's Security Breach Coursework Example | Topics and Well Written Essays - 1250 words

IPad's Security Breach - Coursework Example This report is concerned with understanding the practice of hackers and justification of their act and also how companies can deal with security issues like this for a more secured approach to maintain the privacy of individuals. 1. Determine if hacking into a Web site is ever justifiable, applying your theory to a real-world case in which someone hacked into a system, including the name of the company and details. Hacking is the technique of acquiring information or modification of data from a system or website. Hacking involves several purposes and it’s not always an illegal issue for acquiring information from the websites. Hacking can be conducted for several activities where it can be justifiable for the act as it might not harm anybody or might sometimes be done for the betterment of more secured approach. Hacking can be a justifiable action when all information of the system is free to access which don’t need any intellectual property and security permission. Som etimes hacking is done by people for solely learning purposes to know the system how they operate and the programming techniques used into a system or website. ... The hacker group Lulz Security used a simple SQL overloading technique to hack the systems and retrieve the passwords of the customers (Debatewise, 2011). The explanation of the hackers regarding the issue explains how the companies are less concerned about the information protection and their act is to find the loop hole of the system so that the company can rectify and review their system security to protect important information of customers who can be an important personality who rely on their system to provide information to the websites (BBC Technology, 2011). 2. Create a corporate ethics statement for a computer security firm that would allow or even encourage activities like hacking. As a corporate ethical statement from a computer security firm the statement should be like ‘Good offence is the best defense for the firm’. Computer firm encouraging hacking can influence the hackers to hack their own system and the competitors system to understand the loop hole of the security system. This can give a stronger base to the company to identify the threats to a system from the unethical hackers of the world who can be a possible threat at any point of time. Being offensive to identify the gaps and loops in the system can develop a more secured system which allows hackers to penetrate into different system and implement security programs to void those issues. These types of hackers are known as white hackers. To catch the thieves and employing the same technique of the thieves can recognize and defend the security threats of the firm (Mathew, n.d.). A person knowing the technique of hacking and implementing those techniques to

International Business Finance Case Study Example | Topics and Well Written Essays - 1500 words

International Business Finance - Case Study Example There is transfer of technology between the subsidiaries and the parent firm in the joint venture and the industrial output of the joint venture. Therefore the following can be noted from the joint venture under the strategic option 1. In this multinational capital budgeting there are various factors as well as assumptions that were taken into consideration to determine the expected returns from the joint venture from the parent’s firm perspective. First and foremost the exchange rates fluctuations were taken into account especially when converting the subsidiary earnings into the parent firm’s reporting currency. Given that is challenging to precisely estimate the rates of exchange rates, the determination of the expected returns in pounds were established using the spot exchange rate of  £0.8410/â‚ ¬. Besides, the cost of inflation was taken into account which was charged on the cost of operations to incorporate the depreciation rates and the interest rates on loans based in Germany borrowing rates. Even though the prediction of costs or price completely takes into account the inflation, the rates of inflation rates at tikes can be volatile from one year to another for some states (Madura, 201 1; p. 49). Hence the cost of inflation from the Germany perspective was taken to be 2.5%. Lastly, the financial arrangements were put into account. These include the costs of finance which is captured by the rate of discount and the taxation rate. Nonetheless, when the foreign based projects are partly financed using the subsidiaries in the foreign nations, a more precise strategy is applied to distinguish the investment in the subsidiary and openly take into account the loan repayment of the foreign loans as cash outflows. Moreover, the returns from the Germany were not taxed due to the double taxation treaty that exists between Germany and United Kingdom. The following calculations can be noted under strategic option One; the

Do governments exploit its people Essay Example | Topics and Well Written Essays - 750 words

Do governments exploit its people - Essay Example The third point that will be scrutinized in the essay is how governments exploit her people in cheap labor. Lastly, government use human weakness behavior to exploit her people, thus accepting the existence of certain companies in the country. These companies produce addictive products, some of which are not healthy to the human body. It is always seen as though the employers somehow exploits their workers by not paying them more profits, while in the reality, after a worker looks at his pay check , he will realize the real exploiter is the government. The government takes several forms of taxes before the paycheck even reaches the worker, resulting to net loss. Citizens are nothing more than serfs are under the current taxation system, serving government and those in power (Floyd 16). Over-taxation denies the ability of a worker to decide how best he can use his salary earned. People are therefore, unable to meet their basic needs with the low NET salary. Although the government imposes high taxes on its people they still end up paying more to receive public services e.g. in hospitals and schools. Tax avoidance by huge firms, organization and political leaders undermines the faith of the public in the government. All these injustices and unfairness in taxation by governments erodes the social values that abide t he societies together (Floyd 27). Nevertheless, these taxes are being invested in lobby groups and political investments. Pluralistic ignorance has been used by the government to influence the minority group’s behavior and beliefs to that of the majority to its own benefit (Jens 12). It results people supporting something that they really do not like. Citizens believe other’s supports reflect their true thoughts. Governments have joined in the social media like twitter and face-book making more people takes part on their discussion. The government does this to manipulate people

Artists of the past Essay Example | Topics and Well Written Essays - 1000 words

Artists of the past - Essay Example However, the artistic focus of the Renaissance took a different approach to expression from that of their predecessors. The lessons learned from the ancients contributed significantly to the technical developments in ‘realistic’ painting that emerged during this period through the efforts of a variety of famous artists including Giotto, Masaccio, Botticelli, Leonardo da Vinci, Michelangelo and Raphael. In order to fully understand the artistic revival in painting that took place during this time period, it is necessary to understand the developments each of these artists contributed to the world of art in general and why the ancient world was of particular importance to them. Artists in Florence were able to quickly link the mathematical knowledge of the ancient Greeks and Romans to the proportional focus of their own world. Mathematics was a well-understood concept to the general population of Italy due to its primary importance in commerce. Painters used their foundational knowledge in geometry to create familiar elements in their paintings that would convey their intentions to the greatest possible audience. â€Å"In the same way that a painter could reduce the human form or settings to a play of geometrical figures, so could the merchant simplify all things to geometrical configurations† (Lemaitre & Lessing, 1993: 15). By melding mathematics and artistic expression, artists discovered how to provide their figures with a new impression of weight and volume that had not been previously achieved. This new ability to provide realism in a painting led to even greater explorations into how the world around them manifested itself in visual awareness. This attention to the science of representation eventually led to a systematic development of ever more realistic methods of portraying an image such as the development of dimension, perspective rules, atmospheric interpretation and textural

Love. Flower Arranging PowerPoint Presentation Example | Topics and Well Written Essays - 1250 words

Love. Flower Arranging - PowerPoint Presentation Example The first teachers as well as students were Buddhist members and priests. As time went by, there was the emergence of other schools and the styles changed. Ikebana became a practice and custom among the Japanese people and their society (Ember& Ember, 5). It is stated that until 1868 it was the Japanese men who ordinarily had the skills to make flower arrangements. After the start of the 20th Century, women began to enjoy the practice and they dominated this discipline. In the United States and England, the lush Victorian style of flower arrangement made way for a simplified modern way that was influenced by the Japanese practice of Ikebana. Around the 1930s, there emerged garden clubs that were supported by women who were influential. The practice became popular as more women began to adopt the practice (Fairchild, 112). Women became obsessed with flower arrangements in weddings, tea parties and to decorate their homes. Men, thus, arranged flowers as frequently as tradition called and required them to, but with the practice becoming female dominated, they did not practice the art of arranging flowers as a hobby (Leaman, 45). Presently men are turning to the practice. For instance, in Japan, the male workers are turning to the country’s traditional art form or arranging flowers that was female dominated. They are turning to flower arranging as a way to relieve stress (Lover). In America, men are attending classes to learn the art of arranging flowers (Clarke). The practice of flower arrangement that begun in Japan among men gradually became a common practice among women (Sato and Yoshimura, 200). History has thus repeated itself. The Buddhist priests and noblemen who initially took part in the practice left the art to women. The men managed many flowers arranging schools; however, mostly women dominated those classes. Presently, there is no practice dominated by one gender.

The title of the book I read was 1491 Essay Example for Free

The title of the book I read was 1491 Essay New Revelations of the Americas Before Columbus. It was written by Charles C. Mann. Other books by this author include Noahs Choice: The Future of Endangered Species and The Second Creation: Makers of the Revolution in Twentieth-Century Physics. 1491 is based around Native Americans and how they really lived before European settlers came to the Americas. This is a very interesting, as well as extremely informative book that gives unbiased and well-thought-out information about on the peoples about which that the author writes. about. I personally found this book to be a very good read. Charles Mann is a fantastic writer, and he makes everything about this book interesting. He knows how to put things so that he really grabs the readers attention and keeps you interested to learn more. He is very descriptive and words things in a way that is understandable for me, the reader. He also has a very extensive vocabulary, which makes the reading even more interesting. Mann also uses tons of information that he has gathered. He makes very good points to his topics, as well, and he makes these points very clear. Because of this, I did not find anything that I really disagreed with him on. The book mostly speaks of how much false information is widely believed in the world today about early Americans before Columbus and the Europeans settled in the New World. Many scholars in the past have made false assumptions on about the Native Americans because of their own ethnocentric opinions. For example, today most people view the early Americans as being very nature-oriented, but not very intelligent people who live in small, isolated tribes scattered across the country, who also never did anything to change their environment. However, these assumptions are not true. The Indians actually had a huge impact on their land, mostly for the better. They cleared land to plant more nut and fruit trees, they grew tons of crops, they even created maize. One group in particular, the Beni, was exceptional in the area of purposing land for their its benefit. They built huge mounds in an area that was constantly being flooded. By doing so, this allowed them to grow crops and trees on the mounds. They even made traps below the mounds to trap fish when the area did flood. Overall, I found the book to be very memorable. I really enjoyed reading this book and I will remember a lot of the information that it has taught me for a long time. I cant think of anything that I disagree with the author on, since Charles Mann does make very good points, and he is impressively convincing. I think that the information given in 1491: New Revelations of the Americas Before Columbus will open the eyes of many people and teach a lot of people more about the history of the Native Americans. This is a very good and informative book that gives unbiased and trustworthy information about the early Americans before and after Europeans settled in the Americas.

Nanospheres of Agâ€coated Fe3O4 Synthesis

Nanospheres of Ag–coated Fe3O4 Synthesis Nanospheres of Ag–coated Fe3O4 were successfully synthesized and characterized. Photocatalytic properties of Fe3O4@Ag composites have been investigated using steady state studies and laser pulse excitations. Accumulation of the electrons in the Ag shell was detected from the shift in the surface plasmon band from 430 to 405 nm, which was discharged when an electron acceptor such as O2, Thionine (TH), or C60 was introduced into the system. Charge equilibration with redox couple such as C60à ¢- Ã¢â‚¬â€œ/C60 indicated the ability of these core–shell structures to carry out photocatalytic reduction reactions. As well, outer Ag layer could boost charge separation in magnetic core through dual effects of Schottky junction and localized surface plasmonic resonance (LSPR)–powered band gap breaking effect under sunlight irradiation; resulted in higher photocatalytic degradation of diphenylamine (DPA). The maximum photocatalytic degradation rate was achieved at optimum amount of Ag–NP loading to products. Adsorption studies confirmed that degradation of DPA dominantly occurred in solution. Moderately renewability of the nanocatalysts under sunlight was due to oxidation and dissolution of the outer Ag layer. KEYWORDS: Core–shell Fe3O4@Ag; Plasmonic photocatalysis; Laser pulse excitations; Charge equilibration; Schottky junction; Diphenyl amine Introduction Core–shell nanocomposites combine the profitable properties of both the core and the shell materials (1). Various types of core–shell materials have been technically synthesized owing to their unique physicochemical properties and great potential applications (2,3). Among them, superparamagnetic core–shell nanocomposites do not retain any magnetization in the absence of a magnetic field (4). Hence, they have been broadly used in magnetic resonance imaging, hyperthermia, separation and purification of biomolecules, drug delivery, and catalysis (4,5). The combination of nanocatalysts together with magnetic carriers has attracted increasing attention due to their recoverable nature from the mother solutions in presence of an appropriate magnetic field (6). Recently, to prevent the agglomeration and to further improve the durability of the nanocatalysts, various core–shell like magnetic chemcatalytic and photocatalytic nanomaterials have been developed (7–9). Due to weighty role of Ag based magnetic nanocatalysts in fine and specialty chemistry, different kinds of this bi–functional nanostructures such as Fe3O4–Ag core–shell like NPs, heterodimers, and core–satellite particles have been prepared (11,12). The Ag component in most of the above products was located on the surface of the magnetic carrier whereas structures with an Ag core and Fe3O4 shell are rare. This article aims primarily to unravel the major mechanisms in magnetic core–shell plasmonic photocatalysis. It is important to elucidate the influence of the metal shell layer on the photoinduced charge separation in inner magnetic carrier and reveal the occurrence of charge equilibration between the metal and magnetic semiconductor. Therefore, we have prepared Fe3O4, Ag–coated Fe3O4 (Fe3O4@Ag) in ethanol medium and their behavior under UV–excitation were compared. The factors that control the charge separation and photocatalytic properties of coated nanostructures are also presented in this paper. Besides, we selected diphenylamine (DPA) as a model contamination (13–17) to present powerful and cost–effective photocatalysts. The European Union has listed DPA as a prior pollutant (14). According to the best of our knowledge, the photocatalytic degradation of DPA using Fe3O4@Ag nanospheres has not been reported, previously. The operational conditions in photocatalytic removal of DPA were optimized. The effect of Ag–NPs loading on photocatalytic activity of core–shell nanoparticles was also investigated. Further studies were designed to answer the questions of whether DPA adsorbed on the Ag surface is an important step in its photocatalytic degradation rate or not? Eventually, tentatively reviews on the efficiency and durability of core–shell photocatalysts under sunlight irradiation were checked up. Experimental section Materials and Measurements Powders of DPA, D(+)–glucose anhydrous, thionin acetate salt (C12H9N3S.C2H4O2), AgNO3 (99%), FeCl2.4H2O (>98%), FeCl3.6H2O (>99%), NH3.H2O (25–28%) and HPLC grade acetonitrile (purity 99%) were purchased from Sigma–Aldrich. The hexahydra salt CoCl2 was purchased from Riedel–de Haen Germany. DPA was purified by simple preparative chromatography on a silica gel column (3:1 n–hexane/acetonitrile as a mobile phase) and followed by thin layer chromatography (TLC) monitoring. All other materials were of highest purity commercially available and were applied without further purification. The Britton–Robinson buffer solutions were prepared in 0.04 M concentration. The DPA stock solution was set up by dissolving 10.0 mg of the powders in 100 mL of 60/40 v/v buffer solution/acetonitrile and then stored in a refrigerator. High purity water purified with the Milli–Q system was used in all experiments. The transmission electron microscopy (TEM) study was carried out using a Hitachi S–4300 (Japan) instrument. The crystalline structure of the powders was studied by X–ray diffraction (XRD) with a PHILIPS PW–1840 diffractometer. The UV–vis spectra were recorded on a Biotech Diode–Array spectrophotometer. The IR spectra of the synthesized magnetic NPs were obtained using a Shimadzu FT–IR 8300 spectrophotometer. Magnetic measurements were made with a Quantum Design PPMS Model 6000 magnetometer at 25  °C. The pH values of all solutions were assessed by a model 744 Metrohm pH meter (Switzerland). An external magnet bar of 5 cmÃâ€"5 cmÃâ€"3 cm and power of 1.46 T was used for the accumulation of magnetic NPs. The photodegradation of DPA has been monitored using UV–vis spectrophotometer (Biotech) and a HPLC (KNAUER). The HPLC system used throughout this study consisted of a HPLC pump (KNAUER, K–1001, USA), a sample injector with a 100 à ¯Ã‚ Ã‚ ­L loop and a UV detector (KNAUER, K–2600). The column used was a reversed–phase Spherisorb C18 column (250 mm Ãâ€" 4.6 mm i.d., 5 à ¯Ã‚ Ã‚ ­m). The mobile phase was acetonitrile–water (65:35 v/v) with a flow–rate of 1.0 mL/min. The column temperature was 25  °C. The effluent was monitored at 254 nm. Preparation of Fe3O4@Ag nanoparticles Fe3O4–NPs were prepared using the most conventional reported co–precipitation method first (18), followed by the slow reducing of the Ag+ ions to form a metal shell around the core. Calculated amount of freeze dried magnetic NPs were well–dispersed in 10 mL deionized water. A 10.0 mL portion of 1.0 mM AgNO3 solution was then added into suspension. Glucose was used as a mild reducing agent for the reduction of Ag+ ions (19). Increasing the amount of glucose increases the reduction rate of Ag+ ions. We have found that the experimental conditions that employ molar ratio of metal ions to glucose of 2:1 yields stable suspension of core–shell particles. The condensation deposition of metal particles slowly progresses to yield ~2–3 nm metal shell. With continued stirring of the solution at room temperature, the color slowly changed from black to brownish. Optimized reaction time of ~25 min was achieved based on maximum photocatalytic activity of core/shell clusters. Ag–NPs were also produced in a separate batch using the same experimental conditions. Laser Flash Photolysis Experiment of nano–second laser flash photolysis was performed with 337 nm laser pulses from N2 laser system (Laser pulse width 800 ps, intensity 5 mJ/pulse). Unless otherwise specified, all the experiments were performed under N2 purging condition. Steady–state photolysis experiments were conducted by photolyzing N2–purged solution with UV light (two high–pressure 15 W mercury lamps). Analytical Methods The adsorption and photocatalytic degradation of DPA was carried out in a home–made cylindrical Pyrex reactor (50 mL) with a double–walled cooling–water jacket. UV illumination was conducted utilizing two UV lamps housed over the photocatalytic reactor. In all the experiments, the reactor was fixed 15 cm distant from the light sources. Prior to illumination, equal volumes of DPA and photocatalyst suspension (50 mL volumes) were stirred in the dark for 15 min to achieve the adsorption–desorption equilibrium. Then, UV–irradiated samples (3 mL) were obtained at fixed time intervals and exposed to an external magnetic field for separation of photocatalysts from the reaction mixture. Sample analysis was done by recording the UV–vis absorbance spectra and, simultaneously, injecting of 10 à ¯Ã‚ Ã‚ ­L of solution into the HPLC column. The kinetic data are presented as means of triplicate experiments. Results and discussion Characterization of the prepared nanoparticles The studies of size, morphology and composition of the NPs were performed by means of TEM images, FTIR spectra, XRD patterns, UV–vis absorption spectra and magnetization tests. The TEM images of the core–shell clusters demonstrate that these particles have spherical shape with average size of 9.0 ±2.0 and 12.0 ±2.0 nm, respectively (Figure 1A and 1B). Figure 1B shows that a pale shell was coated on the surface of the black core and the interface between the core and shell is sharp and clear. The surface of the core–shell particle is rather rough. The particle size analysis illustrates that the Fe3O4 particles are coated with silver (Figure 1C and 1D). The change of absorption peaks in the FTIR spectra indicate that the Ag–NPs are coated on the surface of Fe3O4–NPs (Figure S-1A) (20). The absence of characteristic diffraction peaks of Fe3O4 reflection in the XRD pattern manifests complete coating of the Fe3O4 seeds by Ag metal (Figure S-1B) (21). After reduction of Ag ions, a new strong absorption band in the UV–vis absorption spectra is observed at 420 nm, which is assigned to the surface plasmon resonance peak of Ag–NPs (Figure S-1C) (22). The large decrease in the magnetic moment of the Fe3O4–NPs after coating with Ag–NPs is attributed to the presence of nonmagnetic Ag metal in the prepared composites (Figure S-1D) (19). Steady–State Photolysis Figure 2A shows the changes in the absorption spectrum following the UV–irradiation of Fe3O4@Ag colloids suspended in de–aerated ethanol as a steady–state photolysis. Before subjecting to UV–irradiation, the plasmon absorption peak of suspension is seen at 430 nm. It should be noted that the small Ag particles prepared using glucose reduction represent absorbance peak at around 420 nm (19,22). The red shift in the plasmon absorption of the core–shell particles is dependent on the type of the oxide contact layer, refractive index of the surrounding medium, the volume fraction of shell layer (23), scattering effects and adsorbed chemical species (24). For 15 min UV–irradiated sample, the absorption shift attains a plateau with a surface plasmon absorption peak at 405 nm (25). For comparison, no spectral shift was observed during the UV–irradiation of bare Ag–NPs suspension in ethanol (Figure 2B). Transient absorption studies were probed using nanosecond laser flash photolysis (Figure S-2A). Notably, the spectral feature of the transient spectrum (Figure S-2A) closely matches with the difference spectrum recorded in steady–state photolysis as shown in the inset of Figure 2A. We can also repeat the photoinduced charging and dark discharge cycles repeatedly and reproduce the plasmon absorption response to separated electrons (Figure S-3) (24). Estimation of the amount of Electrons accelerated into Ag shell layer Known amounts of concentrated thionine solution (degassed) as a redox couple was injected in small increments into the UV–irradiated Fe3O4@Ag suspension (24). The absorption spectrum was recorded after each addition of thionine (Figure 3A). The presence of any unreduced thionine as the endpoint of titration is marked by the appearance of 600 nm absorption band. The plasmon shift can thus be related to the concentration of thionine added (inset of Figure 3A). From the slope of this linear plot until endpoint and the net shift observed in the plasmon band, we expect a maximum access of about ~35 electrons per Fe3O4@Ag core–shell particle (24). The dependence of the plasmon shift and the number of electrons versus the UV–irradiation time is also shown in Figure 3B. We also selected C60 as an excellent probe to investigate interfacial electron transfer in colloidal core–shell magnetic systems (24). The absorption maximum at 1075 nm manifests formation of C60 anion (C60à ¢- Ã¢â‚¬â€œ) (Figure 4) (24). The electron transfer yield increased initially with increasing concentration of C60 (inset of Figure 4). Photocatalytic activity of Fe3O4@Ag particles The UV–vis absorption spectroscopy and HPLC experiments were performed to follow the photodegradation reaction progress. Figure 5A exhibits the changes in the absorbance spectra of DPA after black–light irradiation in the absence and presence of the nanocatalysts. Photographs from the solution of DPA before and after its photocatalytic degradation are shown in the inset of this Figure. Figure 5B displays the photodegradation monitoring of DPA by HPLC. The separation method of DPA, intermediates, and products was very similar to those reported in literature (26). By irradiation of DPA with UV light for 40 min, a reduction in the chromatogram at 10.5 min in accompanying with the appearance of a new peak at a retention time of 9.3 min is observed. The obtained chromatograms suggest higher photodegradation rate of DPA in the presence of the Fe3O4@Ag clusters (Figure 5B). The photocatalytic degradation kinetic results of DPA are shown in Figure 5C which can be well described by Langmuir–Hinshelwood (L–H) model (27). The rate constant, the linear plots of −ln(C/C0) vs. time was calculated as 0.041 min−1 for the coated particles (Figure 5D). After maintaining DPA–NPs suspension in dark no new peak was appeared in the chromatogram (plots (a) and (b) in Figure 5C). Using surface enhanced Raman scattering (SERS) sensing, Du and Jing showed that oxidation of the aromatic compounds containing a free electron pair on the nitrogen atom is increased using a modified Fe3O4@Ag magnetic NPs probe (28). Figure S-4A exhibits a Langmuir type adsorption isotherm of DPA (29). The effect of initial concentration of pollutant, pH, catalyst concentration, and shell coating time on the photodegradation rate of DPA were also investigated (30,31). Photocatalytic degradation rate constant of DPA is inversely proportional to its initial concentration which implies that the reaction dominantly occurred in solution rather than in the catalyst surface (inset of Figure S-4A) (30). The L–H equation also was successfully used to describe that DPA adsorbed on the Ag surface is not an important step (32). Capping of Ag shell on the Fe3O4 core was confirmed by checking the stability in an acidic solution (HNO3). At pH 3O4–NPs surface (33). Significant shifting (~2nm) in spectra for DPA was detected at different pH values. Figure S-4B shows that the adsorption of DPA on Ag surface decreases, but the removal of DPA increases with the increasing pH. At sufficiently higher pH values, the formation of oxidizing species such as the oxide radical anion (à ¢- O–) could also be responsible for the enhancement (34). The observed results are consistent with the proposed mechanism for the photolysis of DPA in literature (35). Figure S-4C shows the time–dependent degradation of DPA at different concentrations of nanocatalysts (36). At excess concentrations of nanocatalysts, considerable decreasing in the photocatalytic activity can be attributed to the low probability of provoking all photocatalysts in solution together with their self–absorption effects. The photocatalytic activity of Fe3O4@Ag clusters initially increases to a peak and then decreases with increasing coating thickness (Figure S-4D), most possibly due to shading (37–39), strong scattering and light filtering effect (40) of denser coating. Varying the Ag shell thickness and the refractive index of the solvent allows control over the optical properties of the dispersions (inset of Figure S-4D) (41). After 40 min photocatalytic reaction, core–shell nanocatalysts were collected by using a small magnet followed by twice washing with deionized water for reusing (Figure 6). In the first cycle of sunlight irradiation, ~95% degradation of DPA was achieved. However, after 3 recycling reactions, photocatalytic activity of the coated particles greatly reduced to the activity level of bare Fe3O4–NPs. Corrosion (38,42,43), oxidation (42,44) or dissolution of the noble metal coating are likely to limit the use of noble metals (Figure S-5A and S-5B). Moreover, the absence of holes in the outer layer of the core–shell particles was investigated. After each addition of known amounts of concentrated Co2+ solution into the UV–irradiated Fe3O4@Ag suspension no color change was observed (Figure S-5C and S-5D). A series of ROSs, such as à ¢- OH, à ¢- O2−, à ¢- HO2 and H2O2, are subsequently produced from primary active photogenerated holes and electrons (30). 0.1 M isopropanol or sodium azide (NaN3) was added in the reaction solution as scavengers of à ¢- OH radicals (45). I− ions was selected to scavenge the photoholes and resulted à ¢- OH radicals by forming relatively inert iodine radicals (30,46). The obtained pseudo–first–order rate constants with or without the addition of various scavengers are all presented in Table 1. In the presence of isopropanol and NaN3, the pseudo–first–order rate constants decreased from 0.041 min−1 to 0.014 and 0.017 min−1, respectively. The degradation rate of DPA with ~65.0% yield is contributed by the à ¢- OH radicals. Comparatively, the rate constants also decreased very closely to 0.018 min−1 after addition of KI scavengers in the reaction solution. Thus, the contribution percentage of photoholes in the degradation rate was deduced as ~0%. Photocatalytic degradation rate constant of deaerated DPA solution with N2 was roughly stopped, since moved electrons toward the outer layer dont receive oxygen. Therefore, only 35.0%, of the degradation rates were from other ROSs or direct photolysis of DPA. CONCLUSIONS We have scrutinized the photoinduced charging and dark discharging of electrons in a magnetic core–silver shell structure. The shift in surface plasmon band serves as a measure to determine the number of electrons accelerated into the metal shell. The charge equilibration between the metal and magnetic semiconductor plays a significant role in dictating the overall energetic of the composite. These magnetic core–metal shell composites are photocatalytically active and are practical to promote light induced electron–transfer reactions. The enhanced sunlight photocatalytic activity of nanocomposite could be attributed to a synergistic effect between LSPR–powered bandgap breaking effect and bandgap–excitation effect modes (38,47–52). In this photocatalytic system, presence of oxygen for starting the degradation of pollutants is imperative. Exploring the catalytic activity of such composite structures could pave the way for designing novel light harvesting systems.

Birth of A Nation :: essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The Birth of a Nation: 1607-1815   Ã‚  Ã‚  Ã‚  Ã‚  It has been said that the Declaration of Independence was more democratic and for equality and the Constitution was more for a republic that benefited only some people. The Declaration was idealistic the Constitution realistic. That 1776 gave us liberty and 1787 gave us order. Although as unfair as it may sound this seems to be true. After gaining liberty this country had to establish a system that would have order.   Ã‚  Ã‚  Ã‚  Ã‚  When declaring independence, the bulk of the people thought that would be â€Å"†¦to burn the last bridge, to become traders in the eyes of the mother country.† (Garraty 110). John Dickinson had stated, â€Å" ‘Torn from the body to which we are united by religion, liberty, laws, affections, relation, language and commerce, we must bleed at every vein.’ â€Å" (Garraty 110). The people were afraid to break away, they pondered â€Å" ‘Where shall we find another Britain.’ â€Å" (Garraty 110). Eventually independence was inevitable. There was a great mistrust towards both Parliament and George III when the colonists heard that the British were sending hired Hessian soldiers to fight against them in the revolution. The pamphlet written by Thomas Paine entitled Common Sense called boldly for complete independence. This reflected his opinions on George III, calling him a brute, and also attacking the idea of monarchy itself. à ¢â‚¬Å"Virtually everyone in the colonies must have read Common Sense or heard it explained and discussed.† (Garraty 110). John Adams dismissed it as something he had said time and time again. â€Å"The tone of the debate changed sharply as Paine’s slashing attack took effect.† (Garraty 110). A committee was appointed by Congress, consisting of Thomas Jefferson, Benjamin Franklin, and many more. â€Å"The committee had asked Jefferson to prepare a draft† that would soon become known as the Declaration of Independence. (Garraty 112). It consisted of two parts: an introduction which justified the abstract right of any people to revolt and described the theory on which the Americans based their creation of a new, republican government, and a second part that made George III, rather than Parliament, look like the ‘bad guy’. â€Å"†¦The king was the personification of the nation against which the nation was rebelling.† (Garraty 112). â⠂¬Å"The Declaration was intended to influence foreign opinion, but it had little immediate effect outside Great Britain, and there it only made people angry and determined to subdue the rebels.

Effects Of Rape On Women Essay -- essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  Webster’s Dictionary describes rape as the crime of forcing another person to submit to sex acts, especially sexual intercourse. Rape is a crime in which most women cannot defend themselves. The fear of rape plagues every woman at some point or another in her life. The traumatic effects of rape vary from mild to severe, from psychological to physical. This paper will evaluate rape, as well as the effects it has on women, the theory behind male dominance and patriarchy, and differences in demographics.   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"Rape is a crime that combines sex and violence, that makes sex the weapon in an act of violence.†(Kimmel 257) Because of this, rape is often traumatic for the victim of a rape. Many victims undergo what is known as rape trauma syndrome, â€Å"†¦rape trauma syndrome, consisting of an acute stage, where the primary response is fear, followed by a reorganization stage, characterized by phobias, insomnia, sexual dysfunctions, and major changes in life-style.†(Chandler et al pp. 248) These are some of the psychological side effects that women must endure after the rape. There are also other factors, relating to the individual that effect rape trauma they include, â€Å"age, prior sexual experience, ethnicity, and response of significant others to the victim. Factors relating to the sexual assault, such as degree of violence and the relationship between the victim and the assailant also affect trauma.†(Chandler et al pp 249) Overall, is i s safe to say that there are many psychological effects of rape that allows women to fear the attack of a rape. In many rape situations, the victim is raped by an aquaintance, therefore the victim is less likely to report the rape. â€Å"About 15 percent of college women report having been sexually assaulted; more than half of these assaults were by a person that the women was dating.†(Kimmel 233) If more than half of the sexual assaults and rapes are commited by a person that a women is dating or at least knows, then the people that are the rapists are the everyday Joe’s walking down the street, not the psychotic rapist that women are on the look out for. â€Å"Moreover, 20 to 50 percent of women have sustained sexual coercion at least once while dating.†(Burke et al 272) This statistic shows that when women are in a relationship they are much less likely to report a rape. â€Å"Women tend to... ...ies that in rapes where white men are the offender, they usually know the victim, however, in cases where black men are the rapist, they tend to be strangers. Abortion is a very controversial issue in our society. However, people tend to feel differently about abortions for rape victims. The contriversy over the abortion issue is that if a woman is responsible enough to go through the actions to become pregnant, she should be able to have the child. Churches believe that abortion is murder. However, if a woman is raped, she did not give her consent to have sexual intercourse with the offender. According to Schuman and Scott, although there are many people that have mixed feelings about abortion, in other words they believe that it is okay at some times, but at other times they feel that it is wrong, the most extreme pro-life people still believe that abortion is wrong â€Å"when pregnancy results from rape or incest.† (Schuman and Scott 786) In these situations, however, pro-choice believe that women have as much right to choose what happens to their body. According to Kimmel, in some states abortion is only legal in â€Å"cases of rape or of a threat to the mother’s health† (Kimmel 255).

How Stevenson Explores the Nature of Good and Evil in the Strange Case

How Stevenson Explores the Nature of Good and Evil in the Strange Case of Dr. Jekyll and Mr. Hyde The story is about a doctor called Jekyll who has an alternate identity called Hyde. Until the last two chapters it is told from the view point of Mr Utterson; a friend of Jekyll’s who is trying to piece together the story. It uses features of gothic novels such as doppelganger which is an alternate identity. It also uses multiple narratives to make the reader think, it also helps the reader solve the case themselves, and piece the story together, from the evidence given. To a certain extent Stevenson also uses the monster feature in the form of Edward Hyde. In this novel, Stevenson was trying to show that good and evil are not separate within us but are a combined part of us so instead of trying to split them we should except the unity and only then will we be able to make our good side prevail in the struggle of good and evil. One of the features of a gothic novel used is the haunted house. Authors of gothic novels use a character’s house to reflect the characters psychological manner. In this story Jekyll’s house is described as being â€Å"grand and having an air of wealth and comfort†. This mimics Jekyll’s personality as he is portrayed for the reader,† a large, well-made, smooth-faced man†. The description â€Å"smooth-faced man† gives the impression that he is not only hiding his age but also the secrets that come with age. We get the impression that he has something to hide right at the beginning of the story; I believe that through this Stevenson gives us a hint that Jekyll has some thing that he wants to keep hidden. His house however has a backdoor which is described as â€Å"blistered and distained†. This, .. ...mic society by using the split personality of Jekyll and Hyde, which is emphasized by the two entrances to his house, to show the mixed views of people from that time period. He also voiced the fear of most of the society through his monster Hyde, who is created through science but cannot be controlled. I believe not only does he express the fear of science going wrong, he also expresses the view of not playing God, by showing that man might not be able to permanently control what he creates, which is shown by Jekyll loosing control of the transformation to Hyde. He also tries to explain that the good and evil parts of us are what make us who we are and instead of trying to separate them and risk losing control we should embrace them and try through our actions, to let the good side prevail instead of using science to destroy us while trying to do well.

Life of Pi Analysis Essay

A. Example one In the early stages of Life of Pi, Martel mentions a place that Pi and Ravi had gone to visit while on vacation. While looking aimlessly through the window, they noticed three hills. On top of one hill was a catholic church, another a Hindu temple, and the other a Muslim mosque. Each hill portrays each of the religions in Pi’s complex faith. The hills represent Pi’s struggles to understand each religion. Later on, we find out that Pi is caught in between these three religions. He couldn’t completely disregard any of the religions, so each one kept warring for a place in his life. In How to Read Literature like a Professor, Foster repeatedly says how symbols usually have more than one possible meaning. So another possible meaning for the three hills is that each of the warring religions has a different part in his life. The religions are separated by being on each hill, but they live simultaneously in the same general area. Just as, in Pi’s life, each relig ion has its separate area of his mind, but they all partake in his life. B. Example 2 In How to Read Literature like a Professor, Foster also talks about allegories. The relationship between the tiger and Pi can be considered an allegory. A lot of the time spent on the boat is the classic fight of good vs. evil. Pi, seen as a naive child who could do no wrong, takes the role of the good character. Richard Parker represents the savage â€Å"dark side† and takes the role of evil. As the story progresses you see that each could not survive without the other. Richard Parker showed Pi that he could not have survived by being the sweet faultless boy who could not kill and eat a fish. Pi showed Richard Parker that he is inferior to Pi by training him and getting him food. The battle between the two at the beginning digressed to a mutual realization that good cannot always conquer evil and evil cannot always conquer good. â€Å"It’s the plain truth: without Richard Parker, I  wouldn’t be alive today to tell you my story.† (Martel, 164) C. Example 3 Colors play a very important role in Life of Pi. The color orange represents hope and survival. He had an orange life buoy and an orange whistle. â€Å"If there hadn’t been a life buoy, I wouldn’t have lasted a minute.† (Martel, 117) There was an orange tarpaulin that he secured himself in on the life boat. All of these objects helped him survive the sinking and gave him hope for future survival. Richard Parker might’ve been the biggest thing keeping him alive, and he was a 450 pound orange Bengal tiger. Orange is the color of Hinduism as well which shows how religion still gives him hope. The next color is green. It is the symbolic color of Islam. Muslims believe that green represents home and safety. The Algae Island was a blinding green and kept him safe from starvation for a day and let him be on solid ground like his home. Green and orange represent two of the three religions that kept Pi fighting for life. Green gave him safety and a sense of home an d orange gave him hope for survival. 2. Chapter 5: Now, Where Have I Seen Her Before? A. Example 1 â€Å"There’s no such thing as a wholly original work of literature.† (Foster, Chapter 5) Foster presented the idea that, knowingly or not, every author takes ideas from other stories and twists them into their own. In the case of Life of Pi, Yann Martel may not have been thinking about any other particular piece of literature, but Life of Pi, specifically the sinking of the Tsimtsum, is very similar to a very famous story known as Titanic. The Titanic was an enormous ship that was thought never to sink in a million years. According to Piscine, the Tsimtsum could not sink either. â€Å"For days the ship had pushed on, bullishly indifferent to its surroundings. The sun shone, rain fell, winds blew, currents flowed, the sea built up hills, the sea dug up valleys—the Tsimtsum did not care.† (Martel, Chapter 38) But nonetheless, both the Tsimtsum and the Titanic ended up at the bottom of the ocean with a great fight. B. Example 2 Later in the story, Pi reveals a second interpretation of the seven month journey. He replaces the animals with humans like his mother and the cook. In this side, Pi portrays himself as the ferocious tiger, Richard Parker, essentially becoming his doppelganger. While Pi was on the inescapable lifeboat, he was trapped with Richard Parker. In accordance to Foster’s idea that no literature is original, this version could be extremely comparable to The Picture of Dorian Gray and Dr. Jekyll and Mr. Hyde. In The Picture of Dorian Gray, Dorian is forced to deal with an evil side of him after he trades his life for youth. In Dr. Jekyll and Mr. Hyde, Jekyll accidentally creates a concoction that gives him another personality called Mr. Hyde who commits crimes and can easily be named evil. In all three cases, the protagonist is faced with an uncontrollable alternate personality. C. Example 3 Another obvious comparison is the fairy tale Beauty and the Beast. One can clearly see the resemblance between Life of PI and Beauty and the Beast if they figure the plot of both stories. Pi is a normal Indian boy with a somewhat eccentric father who goes through a series of unfortunate events. These events somehow lead to him being stuck in a lifeboat with a Bengal tiger. With time, the tiger becomes his friend and his savior from other wild animals. Belle is a normal young woman with an unusual father. She is also dragged through a series of unfortunate events in which she finds herself stranded in the middle of a forest kept in a castle with another unidentified wild beast that also saves her from a pack of wild dogs and also gradually becomes her close friend and lifelong companion. It is easily assumed that Piscine and Belle, and Richard Parker and Beast, are the same. â€Å"The point is this: stories grow out of other stories, poems out of other poems.† (Foster, Chapter 5) 3. Chapter 26: Is He Serious? And Other Ironies A. Example 1 In How to Read Literature like a Professor, Foster says, â€Å"Irony trumps  everything.† (Foster, Chapter 26) â€Å"I was named after a swimming pool. Quite peculiar considering my parents never took to water.† (Martel, Chapter 3) Water is the element of torture in Pi’s existence. The very basics of Piscine’s life are ironic. He is named after a swimming pool, but throughout the early parts of his life, he is tortured because of his name. His parents and the rest of his family are killed by drowning after a shipwreck. He spends the most grueling seven months of his life surrounded by water. During that time, he comes close to dying of dehydration because he has no water to drink. The whole time he has an abundance of water, but since it is salt water, it will only make his situation worse. He needs water to live, but it has been the main factor in most of the tragedies he has experienced. The irony of Pi’s relationship with water trumps everythin g else in the book, just as Foster said it would. B. Example 2 â€Å"It seemed the presence of a tiger had saved me from a hyena- surely a textbook example of jumping from the frying pan into the fire.† (Martel 136) It is ironic that the tiger, the animal thought to pose the most danger, saves him from the less dangerous hyena. It is thought that Richard Parker would be the end of Pi because he is the most ferocious animal, but instead he becomes Pi’s savior from the other animals. It is ironic that at the beginning of the book, Pi and the rest of the people surrounding him have power over the animals. â€Å"Just beyond the ticket booth Father had painted on the wall in bright red letters the question: DO YOU KNOW WHICH IS THE MOST DANGEROUS ANIMAL IN THE ZOO? An arrow pointed to a small curtain. There were so many eager, curious hands that pulled at the curtain that we had to replace it regularly. Behind it was a mirror.† (Martel 31) Pi came from a world where he was always in a position of superiority, but now on the boat, he is helpless and inferior to the tiger and the other animals. â€Å"I am alone and orphaned, in the middle of the Pacific, hanging onto an oar, an adult tiger in front of me, sharks beneath me, and a storm raging above me.† (Martel 107) C. Example 3 At the start of the book, Piscine is seen as a sweet innocent naà ¯ve boy. In  his mind and religions, doing bad things never led to good things, so he remained innocent and faultless. He held doing the right thing and never the wrong very close to him. Ironically, all of his values went out the window by the end of the book. At first he wouldn’t eat meat because of his religions, but his sustenance on the boat was fish. Murder used to be the worst possible thing someone could do, but he murdered the other man on the lifeboat in order to stay alive. He loved God and his religions so much, but he finds himself screaming and yelling at God. In all of these instances, he loses his innocence, morals, and everything he treasured before the wreck, but without making the hard decisions he had, he wouldn’t have survived. In a way, his loss of innocence is what kept him alive.

Polygraph Research Essay

I began my research thinking I wanted to find out where we were today in our advancement of the lie detector machine and its accuracy. There was a time it was heard of often and considered quite controversial in its legitimacy. My research took me on a different journey then I had expected. A journey discovering that the Polygraph Machine is not only just as controversial today as ever, but also that there appears to be behind the controversy then simply its technology. The Polygraph Machine was traditionally known for its use in lie detection within law enforcement. So I began my search in the Criminal Justice data base of our school library. I came across an interesting article, â€Å"The Truth Surrounding Lie Detection Technology†, written by Rebecca Kanable, a freelance writer specializing in law enforcement topics for the periodical Law Enforcement Technology. Her article, although informative of the details in how the polygraph machine works, what it detects physiologically, and why it might be considered inaccurate, revealed to me there may be more behind the controversial system then simply its technology. She would reference an important sounding entity called the APA (American Polygraph Association), explaining the APA founding, their development, and purpose. After discussing the APA and its extensive research and technology, another official sounding entity was introduced, the NAS (National Academy of Sciences). The NAS reported that contrary to the APA’s pride in their more than 80% accuracy in detecting deception, a majority of the research was unreliable, unscientific, and biased. The APA responded that the NAS findings were confined to a review of the research on polygraph testing in particular, and how it relates to personnel screening. The APA said the NAS relied on 57 of more than 1000 research studies available. The NAS in turn responded that a century of research in psychology and physiology provided little basis for expecting the polygraph test could have extremely high accuracy because the physiological responses are not uniquely related to deception only. At this oint a third entity was introduced, the NACVSA (National Association of Computer Voice Stress Analysis), who also bashed the APA as a flawed method and flawed technology. They would tout how they were supported in agreement by the NITV (National Institute for Truth Verification), yet another official sounding entity. This back and forth seemed a bit odd, as though one or the other had an agenda. That is what redirected my research into whom these entities were, and who was considered more rel iable for the truth about lie detection. First stop was the APA web site (APA. org). I discovered it was a profit driven business selling technology, instruments, research, and advanced training and education programs, as well as advertising their APA magazine. Their primary customers were law enforcement, the legal community, and private sector security screening. It certainly was official, but only in the business sense. Ironically, in my search for the APA web site, it was paired with Antipolygraph. org web site. A location for message board discussions against the polygraph, most of which was specifically directed at the APA. I then moved on to the first entity contradicting the APA in Kanable’s article, the NAS. NASonline. org had nothing to sell, but rather a non profit society established by an act of congress signed by Abraham Lincoln in 1863 and extended by President Woodrow Wilson charged with the mission of providing independent objective advice to the nation on matters related to science and technology. It definitely carried some weight in legitimacy, but to be sure it was not a bias source about this topic, I search its site database for this particular topic, and although it spoke about the technology of the polygraph, it made no specific mention of the APA itself. I was unable to do the same of the APA site as you had to be a paying member to access their database. I felt the NAS response to the APA research was legitimate coinciding with their purpose. What about the NACVSA? It turns out they are a direct competitor of the APA. Upon arriving at the CVSA1. com web site, it was immediately obvious in their solicitation of CVSA software and training. Also solicited were funding assistance through grants from both Walmart and Target to purchase the technology. They tried to hide behind government looking signs and symbols to appear more â€Å"official†. They covered the bases offering insight of cases solved by their technology, who was using their technology, and the history of their technology. They would repeatedly indicate their direct support from the National Institute for Truth Verification. Of course this institute must be official and have a web site. A Google turned up nothing for the NITV, and any mention of them would link you to the CVSA1. com web site. An attempt at Wikipedia also only had them listed as a vendor and tied to the NACVSA. Returning to the CVSA1 website for further investigation, I noticed in small print in the corner the following, â€Å"the NITV is the manufacturer and sole source for the Computer Voice Stress Analyzer†. That certainly did explain their avid support of the CVSA technology. One last scroll through all the sites having mention of the NITV, I noticed a Government site with their mention. Eforia. bis. doc. gov. was a public posting of government documents from the department of commerce. It displayed 11 charges against the NITV of illegal exportation as a private business. So much for that. Realizing I only had information from either the biased private businesses of technology, or the seemingly unbiased sources of government documents and a science society founded by congress, I now wanted to find others with something to say about the polygraph. I went back to the school library database with a refinement for only magazines and newspapers. First was a eye catching title of an article in the Atlantic Monthly by Alan Berlow called â€Å"The Wrong Man†. I gave accounts of cases leading to the conviction and eventual carrying out of death sentences of what would turn out to be discovered as wrongful conviction down the road. The tie with the polygraph came in that the results of the polygraphs, although not admissible in court, did find in agreement with what resulted in their convictions, even in contradiction of there being no physical evidence. This article revealed why the DA in one of those cases was so adamant in ignoring the lack of evidence for guilt and continuing till a conviction. He had knowledge of, and was influenced by, the non admissible results of the polygraph. The Wall Street Journal offered opposite perspectives on the polygraph. In 2003, an Article by Sharon Begley called â€Å"Inertia, Hope, Morality, score TKO’s in Bouts with â€Å"Solid Science†. The dispute with the polygraph was no different then others but with her particular method and terminology of expression. The second Wall Street Journal article, â€Å"For The Polygraph Paradox; Lie Detectors Aren’t Perfect; But convicted Sex Offenders Concede, They May Be Good Enough†, by Laurie P. Cohen. Although alluding to a positive use for the polygraph in spite of its controversy, I doubted the weight of this perspective as the only source of data was that of those who were convicted. It has no opposite data of those who were not convicted. I didn’t take either article as being to far out of bounds as the Wall Street Journal is widely known as quite reputable, whether you agree with a particular article or not. So I then narrowed my search to the immediate locality, and took an article from the Telegram & Gazette. It was a General interest periodical in 1989 with no specific author. It was merely stating a factual outcome of the Massachusetts Supreme Court having ruled the polygraph test as inadmissible in this state. My research into the polygraph, although somewhat informative about its accuracy, was far more revealing about the source of opinions about the polygraph.

Motor Temperature Ratings

A frequently misunderstood subject related to electric motors is insulation class and temperature ratings. This paper tries to describe, in basic terms, the temperature relationships that are meaningful in standard AC induction motors. Some of the same information can be applied to DC motors but DC motors are more specialized and some of the ratings are slightly different. Perhaps the best way to start is to define the commonly used terms.MOTOR SURFACE TEMPERATURESMotor surface temperature is frequently of concern.The motor surface temperature will never exceed the internal temperature of the motor. However, depending upon the design and cooling arrangements in the motor, motor surface temperature in modern motors can be high enough to be very uncomfortable to the touch. Surface temperatures of 75 ° to 95 ° C can be found on T frame motor designs. These temperatures do not necessarily indicate overload or impending motor failure.OTHER FACTORSInsulation life is affected by many fa ctors aside from temperature.Moisture, chemicals, oil, vibration, fungus growth, abrasive particles, and mechanical abrasion created by frequent starts, all work to shorten insulation life. On some applications if the operating environment and motor load conditions can be properly defined, suitable means of winding protection can be provided to obtain reasonable motor life in spite of external disturbing factors.OLD AND CURRENT STANDARDSU frame 184 through 445U frames, were designed based on using Class A insulation. Temperature rise was not precisely defined by the resistance method.Temperature rise by thermometer for Class A, open drip proof motors was 40 ° C. This was generally thought to be equivalent to approximately 50 ° C by resistance. U frame motors were the industry standard from 1954 to 1965 and are still preferred in some industries and plants. T frame, 143T through 449T motors are generally designed based on using Class B insulation with temperature rises by resista nce of approximately 80 ° C. Production of T frame motors started in the mid-sixties and they continue to be the industry standard at this time.SUMMARYA key ingredient in motor life is the insulation system used in the motor.Aside from vibration, moisture, chemicals, and other non-temperature related life-shortening items, the key to insulation and motor life is the maximum temperature that the insulation system experiences and the temperature capabilities of the system components. Table 1 shows the temperature ratings, temperature rise allowances and hot spot allowances for various enclosures and service factors of standard motors. Table 2 shows a listing of temperature related life-shortening factors along with symptoms and cures. You may find this table useful.

APPENDIX Temperature Rise by Resistance Method Degrees C Rise = Rh – Rc/ Rc (234. 5 + T) Where Rc = Cold Winding Resistance in Ohms R h = Hot Winding Resistance in Ohms T = Cold (ambient) Temperature in Degrees Centigrade Note: This formula assumes that the ambient temperature does not change during the test. Example: A small motor has a cold temperature of 3. ohms at 25 ° C (77 ° F) ambient temperature. After operating at full load for several hours, the resistance measures 4. 1 ohms and the ambient has increased to 28 ° C. Calculate the temperature rise: Apparent rise = 4. 1 – 3. 2/3. 2 (234. 5 + 25) = 73 ° C Correcting for 3 ° C increase in ambient: Actual rise = 73 ° – 3 ° = 70 ° C Centigrade Fahrenheit Conversions Actual Temperatures To change Fahrenheit to Centigrade: C ° = (F ° – 32) 5/9 To change Centigrade to Fahrenheit: F ° = (C ° x 9/5 ) + 32 Rise Values Only Degrees â€Å"C† Rise =  °F (Rise) x . 56 Degrees â€Å"F† Rise =  °C (Rise) x 1. 8

Growth and Development of Paksitani Media

Growth and Development of Paksitani Media Pak inherited 05 radio channel son its birth. International Trend played important role in development of Mass Media in Pakistan. Initial decades of Pakistani Media’s history have been dominated by PTV. 2. Government was compelled to permit freedom of media (a)Liberalization of airway in India led to mushroom growth of TV channels (b)In Kargil war India was able to sell its viewpoint to the world and cashed on its version while Pak suffered since it had only the state channel.

Talk Shows Mania has brought more liberalization and has revolutionized the concept since erstwhile taboo issues are being discussed enhancing the awareness of people. 8. The realization in the people and Government about the role of media in society / economic development is there. Indian soap operas have a large viewer ship and their popularity has attracted lots of commercials / advertisement. The commercial aspects attached to the media have contributed to its rapid development. . The Infrastructure Development has taken place. Modern state of art studios /introduction of latest equipment / communication facilities like video conferencing, fax, electronic data transfer, chat / mobiles, etc have brought in a revolution and contributed immensely in the media development. 10. The advertisement / commercials have brought big money to media market. The co ntents of programmes are changing. The high economic stakes attached to the media have brought in Professionalism in all its related fields. Due open market, there is a Scarcity of professional media men 1. The abundance of media outlets has on one hand has created lot of employment opportunities but on the other has posed challenges to the media men to excel in their fields. Jang Group has more than 50,000 employees; media persons are getting enhanced wages. Today we have number of highly professional and well-known media persons who are stalwarts of Pakistani Media and form its backbone. 12. Dozens Of other factors have played role in the development of Pakistani Media. It has been a â€Å"watchdog† on actions of the state, people strengthened the media. Media has played important role in discussing un-touched subjects. It has helped harmonizing the nation on otherwise contentious issues. The competition among the channels is bringing in qualitative improvement in the content and other aspects of programmes Impact of Cable TV Media is strengthening development in Pakistan. †¢Media has supported Democracy. †¢Media has highlighted Public issues. †¢Media has given voice to neglected element of society. †¢Media has become entertainment industry; it satisfies all segments, age groups of our society. CERTAIN NEGATIVE ROLE OF PAKISTANI MEDIA . Consumerism. Our society is consuming all messages being spread by the Media. Media has made us a talking nation, the Mobile Mania-kids, ladies, youngsters all are just talking on the mobile phones. The effect of media is very strong with respect to advertisement on consumer products, instead of being producer media has made us consumer. 2. Moral Vacuum. The dramas, programmes etc shown on media glamorize everything they depict, this has created a moral vacuum and our younger generation is going away for our values (religious, social). 3. Westernization. Western / Indian cultural invasion has taken place through media and is permeating Pakistan society. Our commercials are depicting western values and causing a loss of national identity. There are media talk shows on subjects including sex etc which otherwise are taboo in our society. 4. Not Developing National Image. Our Media is blamed for not developing /projecting our national image. Our media at times uses Indian language; projects Indian Stars in our ads, etc, the threats posed to our values are immense and must be countered. Our country lacks a defined policy to promote national image through media. . False Values. Pakistani Media is projecting false values in its programmes, etc. The projection of family planning, love stories in dramas, hi-fi living styles / material depicted in dramas, etc. are not real and are not based on ground realities. (a)Media lacks compact programmes to educate Pakistani nation. (b)Projected values on media are not congruent with our values / ground realities. It is actually projecting ‘False Values’. (c)Programmes / dramas shown are exaggerated beyond imagination. 6. Manifestation of Interests. Media is negatively manipulating the interests of the people. People of Pakistan are yet not critical / educated enough to realize this manipulation / twisting of facts. There is a famous dictum that â€Å"a lie spoken 100 times becomes greater than a truth†. 7. Exaggeration. Pakistani media is also blamed for overwhelming negative Exaggeration. It glamorizes issues, resorts to negative exaggeration of matters, newspaper headlines are depicting violence, etc all this demoralizes the nation. At times news are given without authentication / confirmation. Unethical material /photographs / scenes are shown on our media promoting vulgarization. Media is Damaging basic fiber of our nation and has created a crisis of misidentification. 8. Dangers to Socialization. We remain fixed to TV screens at the cost of socialization. We cut short our social activities just to watch some favorite programmes on TV. We are not undertaking socialization / giving time to our kids, parents, etc because we are glued to TV etc. This is developing a generation gap. We are giving more time to TV channels and less time to social activity and a sort of isolation is being developed. 9. Sensationalizing / Creating Uncertainty. Our media sensationalize the issues / accidents / incidents. When too much of information is available it creates confusion. Our media is broadcasting every type of information at times even compromising the accuracy and is creating uncertainty. 10. Overloaded with Information. Pakistani Media is discussing so many of topics are actually bombarding the audience with information. Media has flooded us with information. (a)This is psychologically not good for our scenes and disturbs our body functions. (b)Media is stuffing our minds with all types of information and has onverted us into ‘generalist’. Media is misusing our energies. (c)Media has become corporate; it possesses / uses lot of resources and has phenomenal business / financial benefits attached to it, accordingly it bombards the viewers with information. Different surveys are undertaken to find out various methods on how to attract the viewers / readers. Media Marketing has Converted us into recipient.

Critical Analysis 2 Essay Example | Topics and Well Written Essays - 1000 words

Critical Analysis 2 - Essay Example Some rationalist ideas and the remnants of Puritan ideas are seen in the Declaration of Independence. Thesis Statement: The purpose of this paper is explain three examples of Rationalist and remnants of Puritan ideas in the Declaration. Whether Puritan ideas seem to be in conflict with Rationalist elements will be investigated.The works of Thomas Jefferson, Thomas Paine, John Locke and Thomas Hobbes will be referred to. Rationalism is a philosophic belief in natural rights which is perceived and applied by individuals with the help of reasoning powers (Hill 74). Puritanism, on the other hand, is marked by rigid beliefs on living a pure life devoid of indulgence, and a Christian life in the quest of Godliness and the establishment of the truth of God. The period of Enlightenment (1650 to 1800) believed to be an age of rationalism, evolved from the humanistic changes in religious beliefs of the earlier period and the emergence of puritanism. Puritanism began with Protestant reforms in the early sixteenth century to purify the Church and society of corruption and dogma (Cody & Landlow, 1988). Puritanism was the philosophy of life â€Å"which was carried to New England by the first settlers in the early seventeenth century† (Miller & Johnson 1). Thomas Jefferson’s concept of rationality included the belief in natural rights and an innate moral sense common to all people. One example of rationalist idea in the Declaration is Jefferson’s attack on the practice of slavery in the first draft of the Declaration of Independence. He stated that slavery did not follow the natural law of right to freedom which was a basic human right (Hill 82). Another example of a rationalist idea is that â€Å"all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness† (U.S. History 2009). This should mean equal treatment of Africans with white settlers. However,

He always found the best possible solution for the customers and talked to them in a respectable tone that always calmed them down. However, as an executive president, things have changed. He rarely interacts with the customers thus it is difficult to communicate to them. Most of his communications are formal and structured. He also find it difficult to communicate with over 73000 employees all over the globe considering that he cannot even have personal conversations with all employees in his HR department. However, he always finds ways of communicating with employees. One of them includes weekly meeting with all the heads of departments and review various HR issues including employee satisfaction. He also holds meetings with managers who report directly to him at least once every week. Here they review the progress of the employees and challenges faced. He also meets with as many employees as possible outside HR department. He also uses a variety of media to communicate to the world about the policies, benefits and other initiatives conducted by the bank. He records a video four times every year and posts it on the bank’s intranet and allows employees to post their questions online which he and other executives answer immediately on video. There are various sender and receiver skills indicated in this case. The sender skills portrayed include the listening, speaking, writing, thinking and reasoning. Paul is depicted to listen carefully to the needs and challenges of the employees now that he does not interact with the customers anymore (Bateman and Snell 23). He speaks to department heads on various HR issues facing the bank including employees’ satisfaction. He also speaks to employees during various seminars and encourages them on how to overcome the challenges facing them. The
