Representation Of Wolves

Question : Compare and contrast the representations of wolves in Angela Carter’s â€Å"The Company of Wolves† and â€Å"Wolf Alice†. How successful do Carter’s literary appropriations demythologise gender stereotypes.IntroductionIn The Bloody Chamber (1979), Angela Carter’s short stories took a particularly conservative genre and radically subverted it for feminist purposes, deconstructing and demythologizing gender stereotypes in a very creative manner. Fairy-tales were always a very traditionalist and patriarchal literary form, first recorded by aristocratic writers in the 17th and 18th Centuries as moralistic and cautionary stories for children.Politically, their agenda was the exact opposite of Carter, whose feminist views were forged in the new social movements of the 1960s and 1970s. Therefore, none of her female heroines follow these traditional gender roles of being passive victims or the sex objects of men. In â€Å"Wolf Alice†, the nameless female heroine was raised by wolves and was therefore on outcast in human society, unable to assume the passive and domestic gender roles expected of her, while in â€Å"The Company of Wolves†, the Little Red Riding Hood character is depicted as independent and fearless rather than a ‘typical’ female victim of the werewolf.At the end of both stories, the females also voluntarily enter into relationships with the ‘monsters’, claiming control over their own sexuality in defiance of the traditional gender roles. Female characters like these could only exist in a modern feminist or post-feminist context, and stand out as extremely divergent from the norm in society. Body â€Å"Wolf Alice† incorporates some of the elements of Snow White, Alice in Wonderland and Beauty and the Beast. Carter was always interested in the â€Å"’beat-marriage stories of the original fairy-tales†, and to the elements of ‘beastliness’ in all forms of sexuality (Makinen 1992).She was not simply portraying all males as beasts, rapists and monsters but rather making a more feminist statement that woman should take control over their sexual desires and â€Å"re-appropriate it as part of themselves† (Makinen 1992). Alice was raised by wolves and therefore could not speak, ran on all fours and preferred the night over day. In these characteristics, she retained all the â€Å"instinctual nature of her foster family† even after she has been sent to live with the nuns (Walker 77).As the nun-narrator explains â€Å"nothing about her is human except that she is not a wolf† (Wolf Alice 119). She is not even aware that she casts a reflection in the mirror, but believes it is another person. After teaching her some limited skills for nine days, the nuns decide that she really cannot be transformed back into a human, so they send her to the Duke’s castle. He is a nocturnal creature as well, who lives alone and feeds on the living and dead more like a ghoul than a werewolf or vampire.Alice performs domestic tasks for him, sweeping and making the bed, and â€Å"knows no better than to do his chores† (Wolf-Alice 120). Only with her menstruation does she begin to awaken to the fact that she is a female, since she knew nothing about these matters and the nuns certainly did not explain sexuality to her. At this time, she also becomes aware that her breasts are getting larger and begins to wear the old, discarded gowns that belonged to the Duke’s grandmother, although â€Å"she could not run so fast on two legs in petticoats† (Wolf Alice 124).After the Duke is injured during one of his nighttime forays, she begins to kiss his wound and thus transforms him back into a human â€Å"as if brought into being by her soft, moist, gentle tongue† (Wolf Alice 126). In â€Å"The Company of Wolves†, Carter subverts the â€Å"Little Red Riding Hood† tale b y having the female hero willingly join in a sexual relationship with the werewolf. In the traditional versions of the story, of course, the monster is killed by the heroic male hunter, and as Carter describes the legends being circulated in the village, this was the normal fate of werewolves.In Carter’s alternative reality, though, the heroine becomes a â€Å"partner in seduction† (Walker 77). Even before she met the werewolf, she was slowly awakening to her sexuality and her â€Å"breasts had just begun to swell† (Company of Wolves 113). She had heard all the stories about werewolves from the villagers and the dangers of walking alone in the forest, but â€Å"she has her knife and is afraid of nothing† (Company of Wolves 113). To be sure, the werewolf is also described as young, handsome and seductive, so much so the even the grandmother notices his unusually large penis just before he kills and eats  her.Carter was well-aware of the mixture of sexual ity and violence in this creature, and writes that the â€Å"last thing the old lady saw in all the world was a young man, eyes like cinders, naked as a stone, approaching her bed† (Company of Wolves 117). When Little Red Riding Hood enters the cottage, they engage in the expected dialogue about his big eyes and teeth, but she was not a passive victim and laughed at his threats, knowing that â€Å"she was nobody’s meat† (Company of Wolves 118).At the very end of the story, she goes to sleep â€Å"between the tender paws of the wolf† that has just devoured Granny (Company of Wolves 118). Conclusion In â€Å"Wolf Alice† and â€Å"The Company of Wolves†, Angela Carter completely subverted and revised the traditional female stereotypes and gender roles, making her women characters courageous, autonomous and sexually aware. Not all of her leftist and feminist critics agreed with this, however.She was also so frank in her depiction of raw female p ower and sexuality that in in 1987, the New Socialist asserted that Carter was â€Å"the high-priestess of post-graduate porn† (Makinen 1992). Patricia Duncker. Aneis Lewellan and other feminist scholars thought that she had been unable to revise the â€Å"conservative form† of fairy-tales and turn them into feminist literature (Makinen 1992). On the other hand, Charley Baker was correct in arguing that Carter was always exploring â€Å"ways in which women can retain control and defy the systems of oppression that attempt to place them in the role of passive victim† (Baker 76).Similarly, Charlotte Crafts found that Carter’s intention was to â€Å"deconstruct myths about femininity contained within the tales† and challenge the â€Å"patriarchal structures of fairy-tale from within† (Crafts 54-55). Wolf Alice and Little Red Riding Hood were fully autonomous and independent women, who behaved in ways that not even the monsters could have expect ed. Contrary to traditional gender roles and stereotypes they were never passive victim and sexual objects, but instead chose to become involved in relationships with the creatures.To put it mildly, these would most definitely not have been considered appropriate actions for women in the traditional fairy-tales, and both of Carter’s female characters stand completely apart from ‘conventional’ society for that reason. From a political viewpoint, such a recasting of this ultra-conservative and patriarchal genre would only have been possible in feminist era in which liberated and powerful female heroines actually became conceivable for the first time in history.

3 D Optical Storage

3-D OPTICAL DATA STORAGE TECHNOLOGY * *ABSTRACT 3D optical data storage is the term given to any form of optical data storage in which information can be recorded and/or read with three dimensional resolution (as opposed to the two dimensional resolution afforded, for example, by CD). Current optical data storage media, such as the CD and DVD store data as a series of reflective marks on an internal surface of a disc. In order to increase storage capacity, it is possible for discs to hold two or even more of these data layers, but their number is severely limited since the addressing laser interacts with every layer that it passes through on the way to and from the addressed layer. These interactions cause noise that limits the technology to approximately 10 layers. 3D optical data storage methods circumvent this issue by using addressing methods where only the specifically addressed voxel (volumetric pixel) interacts substantially with the addressing light. This necessarily involves nonlinear data reading and writing methods, in particular non linear optics. 3D optical data storage is related to (and competes with) holographic data storage. Traditional examples of holographic storage do not address in the third dimension, and are therefore not strictly â€Å"3D†, but more recently 3D holographic storage has been realized by the use of microholograms. Layer-selection multilayer technology (where a multilayer disc has layers that can be individually activated e. g. electrically) is also closely related. This innovation has the potential to provide terabyte-level mass storage on DVD-sized disks. Data recording and readback are achieved by focusing lasers within the medium. However, because of the volumetric nature of the data structure, the laser light must travel through other data points before it reaches the point where reading or recording is desired. Therefore, some kind of nonlinearity is required to ensure that these other data points do not interfere with the addressing of the desired point. 1. Overview: Current optical data storage media, such as the CD and DVD store data as a series of reflective marks on an internal surface of a disc. In order to increase storage capacity, it is possible for discs to hold two or even more f these data layers, but their number is severely limited since the addressing laser interacts with every layer that it passes through on the way to and from the addressed layer. These interactions cause noise that limits the technology to approximately 10 layers. 3D optical data storage methods circumvent this issue by using addressing methods w here only the specifically addressed voxel (volumetric pixel) interacts substantially with the addressing light. This necessarily involves nonlinear data reading and writing methods, in particular nonlinear optics. 3D optical data storage is related to (and competes with) holographic data storage. Traditional examples of holographic storage do not address in the third dimension, and are therefore not strictly â€Å"3D†, but more recently 3D holographic storage has been realized by the use of microholograms. Layer-selection multilayer technology (where a multilayer disc has layers that can be individually activated e. g. electrically) is also closely related. Schematic representation of a cross-section through a 3D optical storage disc (yellow) along a data track (orange marks). Four data layers are seen, with the laser currently addressing the third from the top. The laser passes through the first two layers and only interacts with the third, since here the light is at a high intensity. As an example, a prototypical 3D optical data storage system may use a disk that looks much like a transparent DVD. The disc contains many layers of information, each at a different depth in the media and each consisting of a DVD-like spiral track. In order to record information on the disc a laser is brought to a focus at a particular depth in the media that corresponds to a particular information layer. When the laser is turned on it causes a photochemical change in the media. As the disc spins and the read/write head moves along a radius, the layer is written just as a DVD-R is written. The depth of the focus may then be changed and another entirely different layer of information written. The distance between layers may be 5 to 100 micrometers, allowing >100 layers of information to be stored on a single disc. In order to read the data back (in this example), a similar procedure is used except this time instead of causing a photochemical change in the media the laser causes fluorescence. This is achieved e. g. by using a lower laser power or a different laser wavelength. The intensity or wavelength of the fluorescence is different depending on whether the media has been written at that point, and so by measuring the emitted light the data is read. It should be noted that the size of individual chromophore molecules or photoactive color centers is much smaller than the size of the laser focus (which is determined by the diffraction limit). The light therefore addresses a large number (possibly even 109) of molecules at any one time, so the medium acts as a homogeneous mass rather than a matrix structured by the positions of chromophores. 2. History: The origins of the field date back to the 1950s, when Yehuda Hirshberg developed the photochromic spiropyrans and suggested their use in data storage. [3] In the 1970s, Valeri Barachevskii demonstrated that this photochromism could be produced by two-photon excitation, and finally at the end of the 1980s Peter T. Rentzepis showed that this could lead to three-dimensional data storage. [5] This proof-of-concept system stimulated a great deal of research and development, and in the following decades many academic and commercial groups have worked on 3D optical data storage products and technologies. Most of the developed systems are based to some extent on the original ideas of Rentzepis. A wide range of physical phenomena for data reading and recording have been investigated, large numbers of chemical systems for the medium have been developed and evaluated, and extensive work has been carried out in solving the problems associated with the optical systems required for the reading and recording of data. Currently, several groups remain working on solutions with various levels of development and interest in commercialization. *3. Processes for creating written data*: Data recording in a 3D optical storage medium requires that a change take place in the medium upon excitation. This change is generally a photochemical reaction of some sort, although other possibilities exist. Chemical reactions that have been investigated include photoisomerizations, photodecompositions and photobleaching, and polymerization initiation. Most investigated have been photochromic compounds, which include azobenzenes, spiropyrans, stilbenes, fulgides and diarylethenes. If the photochemical change is reversible, then rewritable data storage may be achieved, at least n principle. Also, multilevel recording, where data is written in ‘grayscale’ rather than as ‘on’ and ‘off’ signals, is technically feasible. 3. 1 Writing by non*-*resonant multiphoton absorption Although there are many nonlinear optical phenomena, only multiphoton absorption is capable of injecting into the media the significant energy required to electronically excite molecular species and cause chemical reactions. Two-photon absorption is the strongest multiphoton absorbance by far, but still it is a very weak phenomenon, leading to low media sensitivity. Therefore, much research has been directed at providing chromophores with high two-photon absorption cross-sections. Two photon absorption (TPA) is the simultaneous absorption of two photons of identical or different frequencies in order to excite a molecule from one state (usually the ground state) to a higher energy electronic state. The energy difference between the involved lower and upper states of the molecule is equal to the sum of the energies of the two photons. Two-photon absorption is a second-order processes several orders of magnitude weaker than linear absorption. It differs from linear absorption in that the strength of absorption depends on the square of the light intensity, thus it is a nonlinear optical process Writing by 2-photon absorption can be achieved by focusing the writing laser on the point where the photochemical writing process is required. The wavelength of the writing laser is chosen such that it is not linearly absorbed by the medium, and therefore it does not interact with the medium except at the focal point. At the focal point 2-photon absorption becomes significant, because it is a nonlinear process dependent on the square of the laser fluence. Writing by 2-photon absorption can also be achieved by the action of two lasers in coincidence. This method is typically used to achieve the parallel writing of information at once. One laser passes through the media, defining a line or plane. The second laser is then directed at the points on that line or plane that writing is desired. The coincidence of the lasers at these points excited 2-photon absorption, leading to writing photochemistry. 3. 2 Writing by sequential multiphoton absorption Another approach to improving media sensitivity has been to employ resonant wo-photon absorption (also known as â€Å"1+1† or â€Å"sequential† 2-photon absorbance). Nonresonant two-photon absorption (as is generally used) is weak since in order for excitation to take place, the two exciting photons must arrive at the chromophore at almost exactly the same time. This is because the chromophore is unable to interact with a single photon alone. However, if the chromophore has an ene rgy level corresponding to the (weak) absorption of one photon then this may be used as a stepping stone, allowing more freedom in the arrival time of photons and therefore a much higher sensitivity. However, this approach results in a loss of nonlinearity compared to nonresonant 2-photon absorbance (since each 1-photon absorption step is essentially linear), and therefore risks compromising the 3D resolution of the system. 3. 3 Microholography In microholography, focused beams of light are used to record submicrometre-sized holograms in a photorefractive material, usually by the use of collinear beams. The writing process may use the same kinds of media that are used in other types of holographic data storage, and may use 2-photon processes to form the holograms. . 4 Data recording during manufacturing Data may also be created in the manufacturing of the media, as is the case with most optical disc formats for commercial data distribution. In this case, the user cannot write to the disc – it is a ROM format. Data may be written by a nonlinear optical method, but in this case the use of very high power lasers is acceptable so media sensitivity becomes less of an issue. The fabrication of discs containing data molded or printed into their 3D structure has also been demonstrated. For example, a disc containing data in 3D may be constructed by sandwiching together a large number of wafer-thin discs, each of which is molded or printed with a single layer of information. The resulting ROM disc can then be read using a 3D reading method. 3. 5 Other approaches to writing Other techniques for writing data in three-dimensions have also been examined, including: Persistent *spectral** **hole burning* (PSHB), which also allows the possibility of spectral multiplexing to increase data density. However, PSHB media currently requires extremely low temperatures to be maintained in order to avoid data loss. Void* formation, where microscopic bubbles are introduced into a media by high intensity laser irradiation. [7] Chromophore poling, where the laser-induced reorientation of chromophores in the media structure leads to readable changes. *4. Processes for reading data*: The reading of data from 3D optical memories has been carried out in many different ways. While some of these rely on the nonlinearity of the light-matter interaction to obtain 3D resolution, others use methods that spatially filter the media's linear response. Reading methods include: Two photon absorption (resulting in either absorption or fluorescence). This method is essentially two-photon-microscopy. Linear excitation of fluorescence with confocal detection. This method is essentially confocal laser scanning microscopy. It offers excitation with much lower laser powers than does two-photon absorbance, but has some potential problems because the addressing light interacts with many other data points in addition to the one being addressed. Measurement of small differences in the refractive index between the two data states. This method usually employs a phase contrast microscope or confocal reflection microscope. No absorption of light is necessary, so there is no risk of damaging data while reading, but the required refractive index mismatch in the disc may limit the thickness (i. e. number of data layers) that the media can reach due to the accumulated random wavefront errors that destroy the focused spot quality. Second harmonic generation has been demonstrated as a method to read data written into a poled polymer matrix. Optical coherence tomography has also been demonstrated as a parallel reading method. *5. Media *design: The active part of 3D optical storage media is usually an organic polymer either doped or grafted with the photochemically active species. Alternatively, crystalline and sol-gel materials have been used. 5. 1 Media form factor Media for 3D optical data storage have been suggested in several form factors: Disc. A disc media offers a progression from CD/DVD, and allows reading and writing to be carried out by the familiar spinning disc method. Card. A credit card form factor media is attractive from the point of view of portability and convenience, but would be of a lower capacity than a disc. Crystal, Cube or Sphere. Several science fiction writers have suggested small solids that store massive amounts of information, and at least in principle this could be achieved with 3D optical data storage. 5. 2 Media manufacturing The simplest method of manufacturing – the molding of a disk in one piece – is a possibility for some systems. A more complex method of media manufacturing is for the media to be constructed layer by layer. This is required if the data is to be physically created during manufacture. However, layer-by-layer construction need not mean the sandwiching of many layers together. Another alternative is to create the medium in a form analogous to a roll of adhesive tape. *6. Drive design*: A drive designed to read and write to 3D optical data storage media may have a lot in common with CD/DVD drives, particularly if the form factor and data structure of the media is similar to that of CD or DVD. However, there are a number of notable differences that must be taken into account when designing such a drive, including: Laser. Particularly when 2-photon absorption is utilized, high-powered lasers may be required that can be bulky, difficult to cool, and pose safety concerns. Existing optical drives utilize continuous wave diode lasers operating at 780 nm, 658 nm, or 405 nm. 3D optical storage drives may require solid-state lasers or pulsed lasers, and several examples use wavelengths easily available by these technologies, such as 532 nm (green). These larger lasers can be difficult to integrate into the read/write head of the optical drive. Variable spherical aberration correction. Because the system must address different depths in the medium, and at different depths the spherical aberration induced in the wavefront is different, a method is required to dynamically account for these differences. Many possible methods exist that include optical elements that swap in and out of the optical path, moving elements, adaptive optics, and immersion lenses. Optical system. In many examples of 3D optical data storage systems, several wavelengths (colors) of light are used (e. g. eading laser, writing laser, signal; sometimes even two lasers are required just for writing). Therefore, as well as coping with the high laser power and variable spherical aberration, the optical system must combine and separate these different colors of light as required. Detection. In DVD drives, the signal produced from the disc is a reflection of the addressing laser beam, and is therefore very intense. For 3D optical storage however, the signal mus t be generated within the tiny volume that is addressed, and therefore it is much weaker than the laser light. In addition, fluorescence is radiated in all directions from the addressed point, so special light collection optics must be used to maximize the signal. Data tracking. Once they are identified along the z-axis, individual layers of DVD-like data may be accessed and tracked in similar ways to DVD discs. The possibility of using parallel or page-based addressing has also been demonstrated. This allows much faster data transfer rates, but requires the additional complexity of spatial light modulators, signal imaging, more powerful lasers, and more complex data handling. *7. Development issues*: Despite the highly attractive nature of 3D optical data storage, the development of commercial products has taken a significant length of time. This results from limited financial backing in the field, as well as technical issues, including: Destructive reading. Since both the reading and the writing of data are carried out with laser beams, there is a potential for the reading process to cause a small amount of writing. In this case, the repeated reading of data may eventually serve to erase it (this also happens in phase change materials used in some DVDs). This issue has been addressed by many approaches, such as the use of different absorption bands for each process (reading and writing), or the use of a reading method that does not involve the absorption of energy. Thermodynamic stability. Many chemical reactions that appear not to take place in fact happen very slowly. In addition, many reactions that appear to have happened can slowly reverse themselves. Since most 3D media are based on chemical reactions, there is therefore a risk that either the unwritten points will slowly become written or that the written points will slowly revert to being unwritten. This issue is particularly serious for the spiropyrans, but extensive research was conducted to find more stable chromophores for 3D memories. Media sensitivity. 2-photon absorption is a weak phenomenon, and therefore high power lasers are usually required to produce it. Researchers typically use Ti-sapphire lasers or Nd:YAG lasers to achieve excitation, but these instruments are not suitable for use in consumer products. *8. Academic development*: Much of the development of 3D optical data storage has been carried out in universities. The groups that have provided valuable input include: Peter T. Rentzepis was the originator of this field, and has recently developed materials free from destructive readout. *Watt W. Webb* co developed the two-photon microscope in Bell Labs, and showed 3D recording on photorefractive media. Masahiro Irie developed the diarylethene family of photochromic materials. [13] Yoshimasa Kawata, *Satoshi Kawata* and Zouheir Sekkat have developed and worked on several optical data manipulation systems, in particular involving poled polymer systems. 14] Kevin C Belfield is developing photochemical systems for 3D optical data storage by the use of resonance energy transfer between molecules, and also develops high 2-photon cross-section materials. Seth Marder performed much of the early work developing logical approaches to the molecular design of high 2-photon cross-section chromophores. Tom Milster has made many contributions to the theory of 3D optical data storage. Robert McLeod has examine d the use of microholograms for 3D optical data storage. Min Gu has examined confocal readout and methods for its enhancement. 9 Commercial development*: In addition to the academic research, several companies have been set up to commercialize 3D optical data storage and some large corporations have also shown an interest in the technology. However, it is not yet clear whether the technology will ever come to market in the presence of competition from other quarters such as hard drives, flash storage, holographic storage and internet-based storage. Examples of 3D optical data storage media. Top row – Written Call/Recall media; Mempile media. Middle row – FMD; D-Data DMD and drive. Bottom row – Landauer media; Microholas media in action. Call/Recall was founded in 1987 on the basis of Peter Rentzepis' research. Using 2-photon recording (at 25 Mbit/s with 6. 5 ps, 7 nJ, 532 nm pulses), 1-photon readout (with 635 nm), and a high NA (1. 0) immersion lens, they have stored 1 TB as 200 layers in a 1. 2 mm thick disk. [23] They aim to improve capacity to >5 TB and data rates to up to 250 Mbit/s within a year, by developing new materials as well as high-powered pulsed blue laser diodes. Mempile are developing a commercial system with the name TeraDisc. In March 2007, they demonstrated the recording and readback of 100 layers of information on a 0. mm thick disc, as well as low crosstalk, high sensitivity, and thermodynamic stability. [25] They intend to release a red-laser 0. 6-1. 0 TB consumer product in 2010, and have a roadmap to a 5 TB blue-laser product. [26] *Constellation 3D* developed the Fluorescent Multilayer Disc at the end of the 1990s, which was a ROM disk, manufactured layer by layer. The company failed in 200 2, but the intellectual property (IP) was acquired by D-Data Inc. who are attempting to introduce it as the Digital Multilayer Disk (DMD). Storex Technologies has been set up to develop 3D media based on fluorescent photosensitive glasses and glass-ceramic materials. The technology derives from the patents of the Romanian scientist Eugen Pavel, who is also the founder and CEO of the company. First results, 40 nm marks recorded into 3D virtual layers separated by 700 nm, were presented in October 2009 at the ISOM2009 conference. Landauer inc. are developing a media based on resonant 2-photon absorption in a sapphire single crystal substrate. In May 2007, they showed the recording of 20 layers of data using 2 nJ of laser energy (405 nm) for each mark. The reading rate is limited to 10 Mbit/s because of the fluorescence lifetime. Colossal Storage aim to develop a 3D holographic optical storage technology based on photon induced electric field poling using a far UV laser to obtain large improvements over current data capacity and transfer rates, but as yet they have not presented any experimental research or feasibility study. Microholas operates out of the University of Berlin, under the leadership of Prof Susanna Orlic, and has achieved the recording of up to 75 layers of microholographic data, separated by 4. micrometres, and suggesting a data density of 10 GB per layer. [33] 3DCD Technology Pty. Ltd. is a university spin-off set up to develop 3D optical storage technology based on materials identified by Daniel Day and Min Gu. Several large technology companies such as Fuji, Ricoh and Matsushita have applied for patents on 2-photon-responsive materials for applications including 3D optical data storage, however they have not giv en any indication that they are developing full data storage solutions.

Art presentation - Essay Example The Baroque period incorporates artistic works that is based upon catholic and protestant lines. On the other hand, Rococo art mainly focused on the pleasures and interests of the artists rather than events happening around them. Bernini is a renowned artist during this Baroque era and bases his works across Italy. He dominated the art world of Rome in the seventeenth century and received special treatments from the popes, as well as cardinals. He also confronted the contemporary artistic traditions that existed during the era. One of his most creative artwork is The Ecstasy of Saint Theresa. This work involves intense Christian art and is one of the most illustrated artwork that exemplifies spiritual aspects of the Catholic faith. The sculpture has two figures; Teresa and an angel, standing slightly above her pointing a golden spear towards Teresa’s heart. Bernini uses a very rare form to illustrate Teresa’s religious ecstasy when the angel appeared to her with a golden spear. He uses this to illustrate the intense satisfaction and desire in which God had favored her. He also expresses pain that accompanies her favor and intense desire for God’s consent. Bernini emphasizes on her erotic euphoria by displaying her open mouth and closed eyes. He also does this by hanging her limbs. The movement and drama of the sculpture is illustrated by the heavy and tangled fabric of her clothes even though the purity portrayed in her face largely contrasts with the fabric texture. The angel seems to be happily staring at Teresa as he waits to pierce her heart using the spear of divine love. This sculpture illustrates the spiritual pleasure that the saints experience in serving Christ. The imagery employed by Bernini in The Ecstasy of Saint Theresaillustrates the sensual pleasure in a way that conveys the perceptible nature of Teresa’s experience. Baroque art era also dominated across Flanders and Spain. This period is characterized by the breaking of the Lowland

Use of Force Policy in New Jersey - Essay Example It will then evaluate the policy by presenting the advantages and the disadvantages of the policy, and end by submitting some recommendations on the measures which can be used to improve the policy for the law enforcement officers. For the use of force in general, be it lethal or non-lethal, the policy states certain ground points that need to be followed by the police department. These four points include the use of force only by authorized and certified police officials, the use of force only when appropriate and required, the appropriate and reasonable use of force both in intensity and type, and the use of force only to attain lawful or legal ends (Use of force, 2000). Furthermore, the policy defines these lawful ends, in general, as any of the following four situations: when the officer is confronted with resistance directed at himself or others; when there is application of force against the officer or a third party, which could be another officer or an innocent bystander; when there is a threat of damage to property; or when the officer needs to make other legal ends possible, such as making an arrest (Use of force, 2000). For the use of deadly force, the parameters are further defined. Deadly force can be used only when the officer believes the criminal will cause death or serious bodily harm to the officer or a third party and when there are no other methods of stopping him, or in cases of an escape of such a criminal who has been charged with causing serious bodily harm or killing someone, and who the officer has reasonable belief will cause such harm if he succeeds in escaping (Use of force, 2000). Again, deadly force should only be used if there are no other options available and no innocent bystanders are in the danger of being hurt (Use of force, 2000). In 2009 (Hester, 2010), the Attorney General, on the basis of the recommendations and findings of his advisory committee on the use of force policy (Use of force, 2000), introduced the concept and the use of non-lethal weapons or force in police action in the state of New Jersey. This policy concerned mainly with the use of stun guns by police officers (Hester, 2009), although others measures of non-lethal force such as the use of rubber bullets, baton, foam, pressurized water, and other such devices does constitute non-lethal force (Capstick, 2001). There are two versions o f the policy; the original policy, issued in 2009, and a revised version, issued in 2010 (Hester, 2010). The revised version is currently in place (Hester, 2010). The use of non-lethal force does not replace the use of lethal force; it helps merely in reducing the number of incidents in which the police had to resort to lethal force in the absence of any alternative measures (Hester, 2009). Similarly, there are laws defining the use of such force just as there are for lethal force. The use of stun guns is the most common non-lethal force employed by the police (Hester, 2009). According to the old version of the policy, the police could only use this force against those deemed mentally ill or disturbed who were posing imminent danger either to themselves or to the public (Hester, 2010). Such people could be unarmed forcefully and arrested by the use of stun guns (Hester, 2010). The police had to take into account the opinion of an expert on the scene for such matters (Hester, 2010). Stun guns could not be used to forcefully make

However, Socrates thinks that the two assertions cannot be real explanations since the predicates they carry do conflict in one way or another. Plato rounds up by defining justice as â€Å"the greatest good†. In the definition of what democracy is, the philosopher, In Gorgias, through Socrates, Plato, thinks that â€Å" a criminal who does wrong without receiving any punishment is the most wretched person of all† (Plato, 115) Through Socrates, Plato makes attempts that are repeated in a way in order to give good reason for the fact that justice is a tool meant to design all the needs of the people in the society who are powerful and rich. Consequently, Plato was able to prove that the justice had a liaison in the inherent meaning though acting in line with democracy. In that context Plato does claim that there is democracy in Athens which most people in their argument do attest to. He argues through Socrates, that in a society or country, or city that has democracy, it is not easy for an individual to get his or her justice. He defined justice as a virtue that is helpful in the development of an order basis with proper integration of the societal role and does not make interference with any other societal part. The meaning as depicted sounds a bit controversial given the fact that it does relate to the meaning of justice in the traditional realm and the rationale developed basing on fair play. Plato thinks that political justice is â€Å"harmony in a structured political body† Justice is when three parts of the soul (spirited appetitive, and reasoning) work

Strategic Marketing Managment - Essay Example Reebok began as an athletic shoe brand for the women’s aerobics segment because it had substantive consumer insights about the women segment. However, Reebok then changed its positioning strategy and it is now positioned as a lifestyle shoe demanded by several youth markets. The most important reason behind this change in positioning strategy was the marketing research that enabled Reebok to identify and analyse the scope of targeting new groups. Reebok managers had understood that a strong gap exists in the market of teenagers and young adults (youths), where there has been a never-ending demand of lifestyle footwear, apparel and accessories. For instance, Reebok marketers were also aware of the fact that their customers have inclination towards fitness and training, which could be met if they are offered premium quality fitness shoe brands and other supporting products. In this way, Reebok initiated a business expansion plan and launched its new positioning campaign to creat e awareness about company’s expanded product portfolio among Reebok‘s women, men and classics segments. In this way, Reebok enhanced its growth in the United States, North American and Europe markets. Distribution channel members (especially retailers) also played their vital role in positioning of Reebok’s products in the minds of end-users. ... In other words, a market could be divided into segments comprising customers with differences in ages, lifestyle, attitudes, behaviours, norms, standards, desires, income, education, marital status, religion, language, customs and traditions etc. Segmentation is an inevitable part of marketing strategy because it directly impacts marketing mix planning. Reebok has divided its market into 3 core segments that include Reebok men’s, women’s and classics. The sub-segments include Young adults (age 14 – 24 years), adults (age 25 – 40 years), middle-aged (age 40 – 55 years) and seniors (age 56 years and above). In addition, the customers are also divided into middle – middle, upper – middle and elite social classes to increase market reach and sales revenue. Indeed, the shoe-maker which has now become a part of Adidas group targets initially targeted women by coming up with a comprehensive idea of ‘women’s fitness with funâ€⠄¢ to enhance its credibility among women customers. The group reinforced its ideas regarding women’s fitness during 2009 and 2010 when it launched EasyTone, RunTone and TrainTone collections followed by launch of new women’s programmes and partnerships. The second core segment is known as Reebok’s men and the marketers target male customers. The company has established cordial ties with â€Å" world’s top athletes, professional leagues and teamsâ€Å" because these are opinion leaders and they facilitates in brand positioning and building consumer mindsets. This segment has immense potential because of natural inclination of a large majority of males in outdoor sports, athletic ventures, sporting and fitness activities. ReeZig and

John B. Watson and Behaviorism Essay Example | Topics and Well Written Essays - 1000 words

John B. Watson and Behaviorism - Essay Example This essay explains how Watson's work and ideas are different from those of who came before and after him, his contributions to psychology and the relevance of his work. It also looks at the applications of his psychological theory and the treatment methods that have been created from behaviorism. Watson used animal subjects to study behavior before later turning to the study of human behaviors and emotions. Most notably was his "Little Albert" study where he modified the boy's behavior through conditioning (Hothersall, 1995). He used the little boy Albert to test his behaviorist theory. He determined that white, furry objects, such as cotton, did not produce any negative reaction in the baby. But by pairing together a neutral stimulus such as white, furry objects with an unconditioned stimulus such as a very loud noise that elicited an unconditioned response such as fear, he was able to create a new stimulus-response link after several repetitions. Thus when Albert saw white, furry objects, he responded by becoming terrified. This conditioned fear was then shown to generalize to other white furry objects, including feathers and white hair or beards (Hothersall, 1995). Those psychologists who came before Watson such as Thorndike and Sigmund Freud held a totally different view. Sigmund Freud for instance often received harsh criticism from Watson due to his Freudian psychoanalysis theory (Hothersall, 1995). His work on the other hand influenced the modern behaviorists who "believe that all learning is simply conditioning, and that the conditioned response is the true unit of learned behavior." In fact, Watson was an important contributor to classical behaviorism, who paved the way for B. F. Skinner's radical or operant behaviorism, which is pivotal on modern educational systems (Hothersall, 1995). Even Ian Pavlov borrowed very much from Watson in conditioning his dogs. His contributions to psychology Many of the concepts and principles are still widely used today borrows heavily from behaviorism which dominates psychology. In fact, conditioning and behavior modification are still widely used in therapy and behavioral training to help clients change problematic behaviors and develop new skills (Hothersall, 1995). Obviously anyone who wants to manipulate others and compel them to do their bidding particularly governments and intelligence organizations uses the behaviorist theory. In fact, these two groups have spent the most money and the most time experimenting with the subject of behavioral psychology (Hothersall, 1995). Whether or not his work is still used in the field Watson's work is very evident even today. Modern behaviorists believe that their behavioral psychology have greatly influenced the field of educational psychology throughout the twentieth century. Accordingly, the process of education has been perceived in terms of such behavioral concepts as conditioning, reward and punishment as well as behavioral outcomes (Hothersall, 1995). Also, teaching methods have been devised with a view to rewarding desirable learning behavior with most educational aims being formulated in terms of conditioning human beings for desired purposes and behavioral outcome

Statistics Term Paper Essay Example | Topics and Well Written Essays - 1250 words

Statistics Term Paper - Essay Example Interpretation of data and results is one fundamental concern of using statistics in the fields of business and economics. One important statistical tool that for many years has become proven to help businessmen and economists is the analysis of variance (ANOVA). Analysis of variance is a significant component of inferential statistics and it tries to measure the difference between two or more independent groups or variables. In this paper, the proponent tries to discuss ANOVA as a significant statistical tool for business and economics especially in inferential statistics and in tests of difference for three or more independent groups, variables or data. Analysis and interpretation of data are important roles associated with inferential statistics. This statistics has different statistical tools or test for the analysis of interval, ratio, nominal and ordinal data. For making inferences from or conclusions on larger groups or populations, or even in generalizing information gathered in one or more samples, inferential statistics has been proven effective in doing so. The goodness of samples is very important to consider in order so as to ensure effectiveness of inferential statistics. In addition, sampling techniques or procedures are necessary or of great importance prior to the use of inferential statistical tools. In reality, the only way to find what specific tool in inferential statistics is necessary for any research problems or studies depends on the nature of data. It is in this reason that inferential statistics is subdivided into two groups: parametric and non-parametric tests. Non-parametric tests are tests that do not require normal distribution and they utilize both nominal and ordinal data (Bajpai 678). One could say that the distribution is not normal when the value of skewness is either positive or negative. Skewness is positive when the mean is greater than the median and

Cyber education Essay Example for Free

Cyber education Essay Examinations are a means of measuring the students’ learning in school and their capacity for further education. In this regard, the manner of teaching and the students’ learning methods are important. A student, while in primary and secondary schools, greatly relies on the teachers for knowledge, except for a few who do personal researches to further their understanding. More often than not, a student accepts what the teachers offer in school. With this set up, a student has to be abreast and attentive with classroom discussion. He should take down notes and submit in a timely manner the projects and assignments given in school. Participation in classroom discussion and school activities must be encouraged. Interest in school must be inculcated in the mind of every student to support the knowledge and understanding obtained from the classroom. This is to enable the student to have a more enjoyable stay in school. The more enjoyable the learning process is, the more retention of knowledge there. Cyber education is not at all detestable. Students’ learning is more enhanced if the mode of teaching is something which interests him. Cyber education is one that interests me and I think, is equally true with others. Where there is not much interaction with the teachers, the concept that it is more enjoyable makes the information stick into our minds. However, the concern of many that this might lead to no interaction at all with teachers, thus prevents the control of teachers on the students disregarding their personal differences and characteristics, should not be disregarded. Their concern is equally important. Thus, it is humbly proposed that learning be not limited to the traditional type of teaching, but must be combined with cyber school on some selected subjects suitable to it. A student must be exposed to both the traditional type of teaching and cyber school. It is of utmost importance that he is able to retain the information and apply what have been learned in school.

On Distance Learning Essay Example for Free

On Distance Learning Essay Distance education represents a way of teaching with geographically dispersed individuals and groups. Moore related that as early as 1978, regular mail service was used to aid distance education, but the advent of the internet brought new and exceptional dimensions to the world of distance education (10). It offered access to geographically and physically separated individuals to courses and instruction in a more interactive manner through increased education, interactivity among participants, and incorporation of collaborative pedagogical models. But even with the increasing number of courses and degrees delivered entirely online, and the number of supporters this type of education has gained, many still express opposition to it as against the traditional classroom education. Former college teacher James Barszcz’s is one well-known critic of distance education. He strongly asserts in his essay that distance learning cannot fulfill the true purpose of education. The diffusion of the Internet worldwide has literally changed the traditional structure of the school, and, as it can be noticed from the previous examples, it is doing in many different ways that are more and more interesting. It must not be forgotten, of course, that parents keep on worrying about the fact their children’s opinions are circulating all over the world and that this could mean danger and repression for them. These anxieties, however, cannot erase the advantages coming from the introduction of this new technology into the educational are, most importantly, of bringing education to everyone. But what is the true purpose of education, really? In its most basic sense, I strongly believe that the essence of education is to instill in an individual the capability to make out at the world for oneself, to generate one’s own choices, to declare what is black or what is white. In whatever manner this education may come from, it is still learning and discovering about new things that help shape a person into what he is. Distance learning has brought a remarkable means of delivering this education to students in rural or remote areas, so that they make take advantage of continuing learning and give them the ability to schedule learning at times convenient to them. Not only that, a great number of distance education programs cater to the requirements of a lot of diverse people of all ages, sexes, occupations, learning backgrounds and health conditions. Granted that personal contact which is very important in effective education is missing with this kind of education, but as is the situation with all new technologies, there are negative and positive aspects to distance learning. Many instructors, as well as students of distance education miss this. Distance learning can admittedly be lonely sometimes. There is always a price to pay, whether it be big or small. Although this is the case, steps could be done to assuage this drawback. Encouraging students to share something about themselves is one activity that can at least give all participants the feeling that they know something about their colleague and the professor. Additionally, many courses are well supported and, for students who are unable to attend residential events, there are usually opportunities for students to participate in online discussion groups, clubs and societies. It would be noteworthy to point out that for distance learning to be effective, a conducive learning environment needs to be created and maintained. Considerable thought and effort should go into the criteria required for setting-up learning centers and how these criteria would be put into practice and monitored. If this would be followed, distance education, with an extensive record of providing learning to out-of-the-way and distant learners, will become the effective, mainstream method of education and training that advocates claim it to be. In a world where continuous learning is a must, distance education has paved the way for everyone to have access to the educational system without having to physically go to school. Discipline is needed, of course, but it is one value that even traditional schooling teaches students to have. In the end, distance education can only provide a win-win situation for everyone involved in it.

Definition And Characteristics Of Cluster Computing

Definition And Characteristics Of Cluster Computing The evolution of networks and especially the Internet is that nowadays, they need more resources to process data more quickly. Given that the use of a machine could not meet these requirements, it appeared that the act of distributing the spots over several machines to run simultaneously would remedy this problem. In what follows, we describe the different characteristics of a cluster and its various categories. Then we will look networks (architecture, topologies, components ,). Then finally we will discuss how communications are in clusters. 2 Definition and characteristics of a cluster Were talking about clustering, server cluster or farm Computing Technologies for designer consolidate multiple independent computers (called nodes) to enable management comprehensive and go beyond the limitations of a computer to: Increase availability Facilitating the scalability Enable load balancing Facilitate management of resources (CPU, RAM, hard disks, network bandwidth). Clusters of servers are an inexpensive method, residing in the establishment of multiple computers apparatre network that will be a single computer with more capabilities (more powerful, etc..), they are widely used for parallel computing. This maximizes use of resources enables the distribution of different treatments on nodes. A major advantage of a cluster is he no longer need to buy expensive multiprocessor servers but it is now possible to settle for smaller systems that can connect to the following one to other according to changing needs. There are different types of cluster: Extended distance cluster: This is a cluster with nodes located in different data centers separated by distance. Extended distance clusters are connected through a cable which guarantees high-speed network access between nodes until all the guidelines for the fault tolerant architecture are followed. The maximum distance between nodes in a cluster distance scope is defined by the limits of technology and data replication limits networking. Metropolitan Cluster: This cluster geographically distributed within the confines of a metropolitan area requiring authorization for filing of cabling and network components for data replication redundant. Continental Cluster: This is a group of clusters that use networks of roads and service networks public data replication and cluster communication to support failover package between different clusters in different data centers. Continental clusters are often located in different cities or countries and may extend over hundreds or thousands of kilometer. 3 General architecture of a cluster A cluster is essentialy composed by more than one machine (PC, server ), operating system, interconexion technologies, parallel programming environment, middleware and application- cation. Fig 1 : General architecture of a cluster 4 Differents classes of Cluster 4.1 High availibility cluster 4.1.1 Architecture Fig 2 : Architecture of a hight availibility cluster 4.1.2 Definition High availability clusters are used to protect one or more sensitive applications. To do this, the application and all the resources necessary for it will be controlled permanently. For powerful protection application, include this protection in the hardware, the network and operating system. Generally, several products are used to protect multiple applications on a same node but there are solutions that can protect as many applications as you want. With these solutions, we are not obliged to raise all applications and can be made case by case basis. If the cluster software reconnat failure then, initially, it will try to restart the X resource both locally on the same node. Then, if this resource does not restart, the software will start the application switch to another node. In any case, the customer will notice that the application is located on another node in the cluster and their access APPLICATION as before. The typical high availability clusters contain only a few nodes but can use clusters involving 32 or 64 knots. If a cluster contains more than two nodes, so we can define different switching planes. This can be useful to decrease the reduction of performance after a seesaw. 4.2 High Performance cluster 4.2.1 Architecture Fig 3 : Architecture of a hight performance cluster 4.2.2 Definition The main function of a high performance cluster (also called High Performance Technical Clustering HPC) is to increase the power of a PC. To perform this, it is necessary to cut the stain that has been carried out into sub-tasks. The result is the total sub-tasks. The Management Unit to coordinate all the sub tasks and the node that receives the result are the only critical points (single point of failure). These components can be protected via a high availability cluster. The crash of one of the nodes is not a disaster because the work of this node can be done by another. The performance of the cluster but it will weaken the cluster always work. 4.3 Load balancing cluster Architecture Fig 4 : Architecture of a load balancing cluster Definition A Cluster is a load balancing server farm with the same function. A splitter is required to distribute the requests of users each node, it verifies that each node has the same workload. The application will be sent to the node that has the fastest time in response to it. This algorithm can provide better performance at anytime. The performance of the cluster depend on the dispatcher. It will choose the node that has the opportunity to address the application of the user as quickly as possible. Without any protection the cluster load balancing can be a SPOF (single point of failure). Best is to add redundancy to this cluster. If one node is no longer in working condition, the cluster will work as same. The dispatcher will identify the dead node and does include more in its calculations, the overall performance of the cluster then it will decrease. The web-server farms (Google. ..) represent an example of cluster load balancing. 5 Inteconnexion technologies Today, improved network technologies help achieve more efficient cluster. These must integrate the speed interconnect technologies to support the wide bandwidth and low latency communication between nodes in the cluster. Because these two indicators measure the performance of interconnects. The selection of a technology cluster interconnect network depends several factors, such as compatibility with the hardware in the cluster, the operating system, price and performance. In what follows, we will detail some of the most used technologies. 5.1 Myrinet Myrinet (ANSI / VITA 26-1998) is a high-speed network protocol designed by Myricom to be used as system interconnect multiple machines forming a cluster. Myrinet causes much less overhead network on its own communication protocol that most used protocols such as Ethernet, and then offers a higher bandwidth, less interference and less latency when using the system processor. Although it can be used as a traditional network protocol, Myrinet is often used by programs that know how to use it directly, negating the need for system calls. Physically, Myrinet uses two fiber optic cables, one for sending data and one for reception, each connected to a machine via a single connector. The machines in question are connected to each other through routers and switches with low latency (the machines are not directly connected to each other). Myrinet also offers some features that improve tolerance to errors, mostly managed by the switches. These features include flow control, error control and st atus monitoring of each physical connection. The fourth and final version of Myrinet, also named Myri-10G supports a throughput of 10 Gbps and is interoperable in terms of physics with 10 Gbps Ethernet standard (cables, connectors, distance, type of signal). 5.2 Infiniband It is a computer bus has high-speed. It is intended to both internal and external communications. It is the result of the merger of two competing technologies, Future I / O, developed by Compaq, IBM, and Hewlett-Packard, with Next Generation I / O (ngio), developed by Intel, Microsoft, and Sun Microsystems. InfiniBand uses a bi-directional bus with low cost, and enjoying a low latency. But he will remain very rapid, as it provides a throughput of 10 Gbps in each direction. InfiniBand uses a technology that allows multiple devices to simultaneously access the network. Data are transmitted as packets, which together form messages. The InfiniBand is now widely used in the world of HPC (High Performance Computing) as a PCI-X or PCI-Express APPOINTED HCA (Host Channel Adapter) operating at 10 Gbit / s (SDR, Single Data Rate), 20 Gbps (DDR, Double Data Rate) or 40 Gbit / s (QDR Quad Data Rate). It also requires specialized network using switches (or switches) and InfiniBand copper cables o r type CX4 Fiber for long distances (using an adapter to Fiber CX4). The protocol allows the use of InfiniBand these cards natively by making use of the protocol VERBS or software overlays: IPoIB (IP over InfiniBand) that presents an Ethernet layer on top of Infiniband and thus the possibility to configure an IP over InfiniBand ports. SDP (Sockets Direct Protocol), which presents a socket layer over InfiniBand. SRP (SCSI RDMA Protocol) which allows frames to encapsulate SCSI over InfiniBand. Some manufacturers offer windows InfiniBand attached storage rather than Fibre Channel. These overlays offer lower performance in the native protocol, but are easier to use because they not require the redevelopment of applications to use the InfiniBand network. In the world of HPC libraries MPI (Message Passing Interface) generally use the native layer to deliver directly VERBS best possible performance. Gigabit Ethernet Gigabit Ethernet (GbE) is a term used to describe a variety of technologies used to implement the Ethernet standard has a data transfer rate of one gigabit per second (or 1000 megabits per second). These technologies are based on twisted pair copper cable or fiber optics. They are defined by the IEEE 802.3z and 802.3ab. Unlike other Ethernet technologies, Gigabit Ethernet provides flow control. The networks on which they are located will be more reliable. They are equipped with FDR, or Full-Duplex Repeaters that allow multiplex lines, using buffers and localized flow control to improve performance. Most of its switches are constructed as new modules for different models of compatible Gigabit switches already exist. 5.4 SCI (Scalable Coherent Interface) SCI Scalable Coherent Interface, IEEE Standard 1596-1992 is a providing a shared memory system has low latency across a cluster. SCI can use a memory extending to the set of the cluster, thus ridding the programmer to manage this complex. This can be seen as a kind of BUS INPUT / Output processor-memory via a LAN. The facilities of programming it offers and the fact that SCI is an IEEE standard has made it a fairly popular choice for the interconnection of machines in a high performance cluster. 6 Comparison of Interconnect technologies This comparison includes the main criteria for judging the performance of a cluster and by needs and resources of each organization technologies will vary. Gigabit Ethernet Infiniband Myrinet SCI Bandwidth 850 230 Latency (Â µs) 10 01/02/10 Max nods 1000 > 1000 1000 1000 Table 1 : Comparison of Interconnects technologies 7 Performing test A group of authors Pourreza, Eskicioglu and Graham led the ratings performance of a number of technologies we have presented above. The parameter they have taken into account is the timing of the execution of the same applications on cluster nodes identical. They tested a number of standard algorithms namely NAS Parallel Benchmark and the Pallas Benchmark and some applications of parallel computing the real world on the first and second generation Myrinet, SCI, but also on FastEthernet (100Mbps) and Gigabit Ethernet (1000Mbps). The results obtained are presented below. These tests were performed on a cluster has eight nodes under RedHat 9.0 with kernel 3.2.2 and gcc 2.4.18smp. Each node has: A dual Pentium III; a 550 MHz processor with 512 MB of SDRAM memory shared; local disks (all activities of entry-exit in the experiments are performed on local disks to eliminate the effects of access to NFS). Each node also has the first and second generations of Myrinet, Fast Ethernet, Gigabit Ethernet network interface card and point-to-point SCI (Dolphin WulfKit). All interfaces of network cards are connected to dedicated switches except those of SCI which are connected to a mesh configuration (24). 7.1 Bandwidth Fig 6 : Bandwith of four interconnects H. Pourreza,Graham,Eskicioglu Latency Fig 7 : Latency of four interconnects H. Pourreza,Graham,Eskicioglu The basic performance of different interconnect technologies in terms of bandwidth and latency are presented respectively in Figures 1 and 2. This indicates that Fast Ethernet is significantly lower than all the others, and Gigabit Ethernet is visibly lower than SCI and Myrinet shows that despite a bandwidth substantially similar. From these results, it is clear that Fast Ethernet is probably only suitable for applications related to the calculation. Conclusion The competitive nature of business and progress of research fields have created a need for computer systems scalable, flexible and reliable. Advanced applications now require a large computing power. Clusters provide a solution to his problems. Clusters represent a promising future for this new concept provides scalability in the world of data processing. Thanks to the different technologies we use to implement them, there are networks that are becoming performants. Because these new technologies can have high bandwidth and low latency. Performance tests carried out have demonstrated that some technologies were more efficient than others. When setting up the cluster, it should choose an architecture and an appropriate network topology to avoid excessively reducing network performance. The use of cluster is less expensive than buying a supercomputer, since it uses the resources of several machines on which the spots are distributed and most of the clusters using the Linux operating system which is a powerful system around because of its flexibility, workability and low cost.

Big Fun in BookWorld: Jasper Fforde’s The Well of Lost Plots :: Essays Papers

Big Fun in BookWorld: Jasper Fforde’s The Well of Lost Plots The Well of Lost Plots is a highly entertaining romp through the strange, yet mostly familiar world from the imagination (and extensive reading list) of Jasper Fforde. This is the third book in a series that continues to grow. In the first two books, The Eyre Affair and Lost in a Good Book, our heroine Thursday Next is a literary detective for the Special Operations Network (or SpecOps) of the British Police Force. She verifies the authenticity of rare books and manuscripts, investigates thefts and other criminal behavior, and looks into anything out of the ordinary related to the literary world. Thursday Next’s world is our world – with a few twists. Due to the invention of time travel, and subsequent disruptions of the time line, things have turned out a little different in Thursday’s mid-1980’s England. For instance, when the series begins England is still fighting the Crimean War. This world is a strange mixture of high-tech and no-tech. The airplane was never invented, nor apparently needed. But mega-corporations such as the sinister and omnipresent Goliath Corporation engage in genetic experiments that, among other things, reintroduce from extinction both the Dodo bird and Neanderthal man. In The Eyre Affair Thursday discovers that she has an unexpected talent – she can read herself into books. She discovers BookWorld, the world behind the world of fiction, where characters from literature have lives beyond the pages of their books. In Lost in a Good Book Thursday becomes an agent for Jurisfiction, the agency that keeps order in BookWorld. She is recruited by Miss Havisham (yes, from Dickens’ Great Expectations) and, in addition to retrieving a former enemy from Poe’s The Raven, she manages to save all life on earth from turning into a gooey pink sludge. In The Well of Lost Plots, the third book of the series, Thursday is living in BookWorld hiding out from the Goliath Corporation and hoping to find some peace and quiet. What she finds instead is bureaucracy, politics, intrigue, and a messy underworld; all of which fuel the creative process of fiction writing. When Jurisfiction agents start dying in freak accidents, Thursday begins an investigation that leads her to uncover corruption at the highest levels in BookWorld. This series is the embodiment of metafiction, which The American Heritage Dictionary, 4th Edition (http://www.dictionary.com) defines as â€Å"fiction that deals, often playfully and self-referentially, with the writing of fiction or its conventions.

Realism in Oedipus the King Essay -- Oedipus the King Oedipus Rex

Realism in Oedipus Rex  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚        Ã‚  Ã‚   This essay will examine a feature of Sophocles’ tragedy which causes the reader to doubt the realism underlying the literary work. Specifically, the essay will consider the feasability of the belief at that time – that the Delphi oracle possessed credibility with the people.    At the outset of the drama the priest of Zeus and the crowd of citizens of Thebes are gathered before the royal palace of Thebes talking to King Oedipus about the plague which is ravaging the city. The king is sorely troubled and laments the sad situation. Then he says:    I have sent Menoeceus' son, Creon, my consort's brother, to inquire Of Pythian Phoebus at his Delphic shrine, How I might save the State by act or word. And now I reckon up the tale of days Since he set forth, and marvel how he fares. 'Tis strange, this endless tarrying, passing strange. But when he comes, then I were base indeed, If I perform not all the god declares.    From this passage it would appear that the king has full faith in the awaited advice from the oracle at Delphi. Is this notion historicaly accurate? Did Sophocles’ contmeporaries actually put such trust in their pagan gods and goddesses? As Brian Wilkie and James Hurt state in â€Å"Sophocles†: â€Å"Humanity in his plays is an integral part of a world-order that can be only partially understood at best. The cosmic system includes, besides human beings and nature, those darkly inscrutable forces identified – inadequately – as the gods and fate† (718). When Creon returns, he gives his report publicly:    CREON Let me report then all the god declared. King Phoebus bids us straitly extirpate A fell pollution that ... ...74). Cypselus consulted the oracle, and on the basis of its answer, set to work to make himself master of Corinth (376)which he ruled for many years.    Thus we have seen that Sophocles is not being imaginative when he bases the action of the tragedy Oedipus Rex upon the words of the oracle at Delphi. It is wholly consistent with historical data available from that time period of the fifth century BC.    WORKS CITED    Herodotus.   The Histories. Translated by Aubrey de Selincourt.

Advantages and Disadvantages of Prison Privatization Essay

The need for a well-built, reliable incarceration service and program is truly of great social, state, federal, and national concern. As the sense of maintaining justice, peace, and order amongst the communities and state-areas is of a national issue, it is only natural that the government and other public officiating bodies are tackling such social matters. However, at the event of prison privatization, many discussions have spurred it as a sound and trusty alternative for various difficulties that public incarceration systems have been facing. As any arguable issue is compromised, advantages and disadvantages present themselves. Economic and Monetary Advantage—Real and Perceived There are on-going arguments which discuss the true fiscal advantage of having a privatized prison system, specifically in terms of whether its contribution is significant or not. Those who support the push of such a privatized system argue that a noteworthy percentage of costs can be saved. In fact, â€Å"advocate for privatization maintain that the private sector management and operation of prison can cut costs by as much as 20%† (Carey, 1997 cited in Cheung, 2004, p. 1). Other studies and research have been done to better prove the cost efficiency of such a system. Organization have made efforts to support this particular privatized advantage, finding a direct relation between sending and keeping inmates in a prison system run by the private sector. Michael Hallett and Amy Hanauer (2001, p. ) writes: A 2001 report from Policy Matter Ohio documented a long-standing practice by Ohio prison administrators who manage contracts with private facilities. The practice is known as â€Å"cherry picking† and involves â€Å"sending less expensive inmates to private facilities, artificially inflating reported cost savings† (cited in Raher, 2002, p. 4). Moreover, the use of a labor base belonging to private sector presents cost-saving advantages as it maintains a sense of control over employee compensation and benefits. Though figures have been given, those who oppose such privatization rebut with delivering disputes that this is more of a misleading notion than fact. Greg Jaffe and Rick Brooks (1998) explain: In a 1996 General Accounting Office (GAO) review of several comparative studies on private versus public prison, researchers acknowledged, â€Å"because the studies reported little difference and/or mixed results in comparing private and public facilities, we could not conclude whether privatization saved money† (cited in Cheung, 2004, p. ). As this is a debatable issue, there are ever combating findings and views upon this matter. It is best to reconsider whether or not there is any actual and beneficial fiscal impact of privatized prisons. Nevertheless, James Austin and Garry Coventry research and examine in terms of future trends that â€Å"a number of companies operating privatized prisons is likely to decrease as competition and costs of doing business increase, thus forcing a con solidation of firms within the industry† (Austin & Coventry, 2001, p. xi ). Hence, the logic of presenting a privatized prison system, a seemingly cost-effective option, still holds problem. Thus, this does not really address solutions to replace fully the traditional, non-privatized, prison system. Quality Process of a Privatized Operation—Safety and Reliability The discussion of quality and reliability of a privatized prison system service and its standing to survive pressing conditions of what prison and its inmates demand is of valuable concern more than anything else. Seemingly, however, prison in a privatized sector is not an ideal fit. There are issues of safety, for the inmates, guards and public, that questions these. Again, James Austin, and Garry Coventry also examines that physical assaults on guards and staff by inmates were almost more significantly recurrent in private prisons than in government-run prisons and physical assaults on fellow inmates were more significantly recurrent in private prisons (Austin & Coventry, 2001). Hence, with the assorted dangers of a privatized system, it then places its integrity on shaky ground. Sentencing Policy and Profit Motive It seems that the correlation of the sentencing policy and profit motive is in line with each other at a prison belonging to the private sector. Since profit maximization is the main objective of a private-based organization, it would seem logical to tip the scales of sentencing towards the private prison’s benefit, presenting the possible use of profitable injustice with conditions that may violate particular prison laws and prisoner rights. This presents a disadvantage more over the conscious effort to exercise the true essence of human justice. Putting the promise of profit ahead of justice is a form of corruption that disrupts the natural hand of the supposed trustworthiness of a true and unbiased justice system. Furthermore, Amy Cheung (2004) adds: â€Å"And because most private prisons operate on a per diem rate for each bed filled, there is a financial incentive not only to detain more inmates more inmates but also to detain them for a longer period of time† (p. 4). Lack of Public Oversight With the privatized prison system, the public is freed from paying taxes that are allocated to maintain and ensure a reliable prison system. However, as tax exemptions are placed, the public ability of oversight in terms of approving and disapproving upon issues of new prison facilities amongst communities, etc, is sacrificed. Conclusion Prison privatization has both advantages and disadvantages that hold key elements for debate. Nonetheless, what must be prioritized is the valuable role of the justice system and the ability of a dependable prison system, whether private, public, or mixed, to render the hand of truthful justice.

A Philosophical Approach To Animal Rights Philosophy Essay

A Philosophical Approach To Animal Rights Philosophy Essay Rights are certain codes of freedom or some sort of allowed medians based on certain legal system or ethical theories. Every organism born with some rights, it is the society or the system which understands and allocates these norms to that particular individual and also does the grading among the living beings. This paper is mainly concern with the animal’s rights, their legal position in our society and also their autonomy. Human being is by nature a selfish being and if we look through the window of history, man has been using animals for their benefits without caring about their rights and freedom. From very beginning human and animals are in close interactions with each other, human use them as food, make them to do their work, use them for decoration purpose, use them as watch man, use their lather and also use them for experimentation. In spite of hundreds of benefits which animals provide to human, human do no or less care about their rights and legal position and is busy in harming animals and violating legal norms which should be given to these animals. Non-human animals should be given rights and protection in the society and there should be a governing body which should govern and implements these rights and norms. It is a fact that animals are an important component of a country economy, the use of animals is a bit compulsory nowadays. Many industries such as lather industries, diary industries, pharmaceutical industries, food industries, and textile industries all rest on animals and their products. I have no objection regarding the use of animals but this use should be justified and limited and if the use is experimentation then the 3Rs Principlesshould be followed, which are Reduction, Refinement and Replacement. By reduction he means that reduce the number of animals used, if you are using 100, use 50. Similarly by refinement he means that refine your method so that less or no harm is given, by replacement he means that replace higher a nimals by lower animals or animals by computer models. There is a difference between use and cruelty, use and harm, it is clear that their use cannot be avoided but what can be done is to follow certain rules and guidelines regarding their use. These rules should be provided by an ethical committee and implemented by government. This paper will give you an idea about the thinking of various philosophers and great persons regarding animal rights from the very beginning till date. Ancient world and Animals: Human dominancy has been reported in â€Å"Genesis† which quotes that Adam was told to be dominated over fishes, creatures of winds and all creeping creatures, keeping this in mind man had violated animal rights for centuries and centuries. But in fact the quote does not mean that human should be cruel to animals; it only represents supremacy of humans over other creatures. On the other hand certain people believe that they are inferior to human because they lack rationality and language. These two reasons were considered as a right to use animals as food, clothing, for entertainment and as research subject.

Ships and vessels transported it across city-states in cases of warfare or trade activities. If someone found my pottery today, I would want the pottery itself to reflect on the revolutionary element of Greek society. The artistic movements of Greek, as a society, should focus on narrating the story of the birth of the first democracy, ancient Athens, through an artistically based kind of life. In the brutal world of the 5th Century BC, there emerged a society of equals in Greek, which was the ultimate reflection of the pottery artistic work if it were to be seen today. The aspects of life in Athens that encouraged cultural contribution of various philosophers, writers and artists include the following factors; firstly, the inbuilt spirits of Greek inhabitants is of an ever formulated trial and era aspect of the society. Secondly, Athens gave rise to various philosophers because of the emergence of educational activities through artistry. For instance, the Greek revolution overly began at the dawn of a simplified democracy in 508 B.C. with the revolution of common people against the aristocratic rule. This shows the complex nature of Greek subjects towards their leaders and the epistemological view of the world. The Greeks defeated the Persian Empire through an extraordinary self-sacrifice. When the Persians confidently arrived in the battlefield to tackle their Greek counterparts, their courier Phidipphides had already sought a 140 mile run to Sparta in two days. This was done in order to solicit help from Sparta’s army. The outnumbered Athenians henceforth fought to uphold their freedom rights, defeat the Persians and send them to Asia. The institution of ostracism was a formally implemented Athenian democracy. This democracy had a function of expelling defiant citizens from the
