X-ray Photons - Essay Example The intensity of beam if then given by the number of photons passing through a given area per unit time. As the intensity is also proportional to the square of the electric field it follows that magnitude of the field is quantised (Dendy & Heaton, 1999). Thus A beam of x-ray photons is heterogenous and presents both fields: electrical and magnetic. Because X-ray beam is not originated from a point source it's divergent by its nature. In this way the magnification of the image could be achieved by the increase of the focus distance (direct dependence). Because of the existence of two different types of photon interaction within the x-ray tube there is important what peak voltage is used. The energy of electrons depends on the voltage between the anode and cathode. Higher peak voltage produce photons with higher energy (Aichinger et al., 2003). Thus measurement of the practical peak voltage is used for the quality control of X-ray units (Ramrez-Jimnez et al., 2004). There are some types of X-ray photons dependently on their origin and type of interaction with target atom. If the projectile electron interacts with an inner-shell electron of the target atom rather than an outer-shell electron than characteristic x-radiation can be produced (Christensen et al., 1979;). Contrarily to the characteristic interaction Bremsstrahlung (braking) x-radiation occur when the projectile electrons lose their kinetic energy in the interaction with the nucleus of a target atom (Aichinger et al., 2003). Actually, X-ray tube is very ineffective device - only small part of energy is transformed in X-ray beams while the rest just produce heat (Aichinger et al., 2003). Only small part of the anode surface is involved in x-ray production. This area is called as the "focal spot". There is known that smaller focal spots is more useful for imaging purposes because they generate less blurring and provide better visibility of image details. Thus X-ray tubes with small focal spots are useful for decrease of radiation loading (Aichinger et al., 2003). X rays interact with irradiated substances in form of photoelectric effect, dispersion and forming of pairs "electron-positron" (Aichinger et al., 2003) They have high penetrating capacity, its property is described by formula: I=I0e-rt, where I0 - is intensity of the beam of X-rays, - attenuation coefficient (Aichinger et al., 2003). The depth of penetrating depends on the half-value thickness, i.e. the thickness of an absorbing substance that reduces the intensity of x-ray beam to half its value (i.e. I0/2). The half-value thickness depends on the attenuating properties of the substance itself and the penetrating power of the radiation incident upon it. This property is used for such radiographic tests as roentgen-densitometry when density of tested object is compared with etalon, e.g. aluminium equivalent (Wells & Ryan, 2000). Another practical application of the half-value thickness knowledge is shielding/filtration. Protective equipment is an example of added filtration. Filtration allows increasing the average energy of X-ray beams and reduce amount of low-energy photons. It's helpful for radiation dose control. Minimum adequate filtration of the x-ray beam is achievable at the half value thickness which is equal or more than 2.5 mm of aluminium (Bushberg et al., 1994). Both Bremsstrahlung and characteristic radiation are emitted in the anode

Genetically Modified Food Essay Example for Free

Genetically Modified Food Essay In 1973, scientists discovered something that has the potential to change the world we live in forever they discovered Genetic Modification. Genetic modification is exactly what it sounds like it is the modification of genes inside a living organism. This of course could be used on humans or animals but as soon as this discovery was made safety precautions were put into place to stop people using this new technology in the wrong way. The secret to genetic modification of genes lies in the plasmid. A plasmid is a ring of DNA inside bacteria and can be used to change the genetic message inside the bacteria. For example if you were to want to create insulin you would extract the insulin producing gene from the pancreas cell of a human and cut open the plasmid and insert it the gene. This new DNA created is called recombinant DNA. The bacteria would then go on to produce human insulin. Since this is the basis of how this technology works it can also be transferred to foods. Scientists are now looking how they can genetically modify food in the world to make it better and hardier than the food nature produces. Some foods have already been genetically modified and are being grown widely throughout the United States. Crops such as Soya, Cotton, Maize and Potatoes are already modified and sold throughout the country. Scientists have genetically modified these crops to make them resistant to herbicides (weed killers) and to create their own poison that kills pests that eat the crop. These highly advanced crops are more likely to produce food for harvesting than normal crops would. With this new genetically modified food it raises issues about just what can be done with it. Places such as Africa which have lots of drought may find that a crop could be developed that would be resistant to drought and could actually survive the harsh conditions and produce crops. A crop that is being developed right now is rice that contains vitamin A that can easily be absorbed into the body. Since poorer countries have a serious lack of vitamin A this new crop would help them to gain the nutrients they need to be healthy. These two crops could be a huge help to world hunger. More food could be produced and the food would make the people that eat it healthier. However, there cant only be good news about GM food or else it would be put into production throughout the world. Many are concerned that GM crops could have a huge impact on the environment. Many say scientists are playing around with something that they dont understand and could damage wildlife and the environment. Concerns of how the GM crops would affect wildlife are a big concern. It has been found out that the crops that have built in poisons to kill pests could also kill other animals such as butterflies. This could have an impact on the food web that the butterfly is apart of. There are also worries of a superweed being created accidentally by the gene that makes the crop resistant to herbicides. People are worried that this gene could get into a weed and make it resistant to the chemicals that are used to kill it. This would make it very difficult to rid crops of weeds and they could have the potential of spreading across the world. Other worries of GM crops include cross-pollination of other plants with these super crops. Farmers that grow organic food may find that some pollen from a GM Crop has pollinated with their crop and made a new hybrid plant. Overall it would appear that there are both positive and negative aspects to the genetic modification of crops. On the positive side there is the possibility that world hunger could be helped by these new crops. However there are the negative aspects that GM crops could have an irreversible impact on the world and environment in which we live in. If further tests were conducted on how GM crops would affect the world in which we and many other species live, maybe there could be some agreement on how we should go about using this new technology that has been discovered. Eventually genetic modification may be taken to new heights by genetically modifying humans and animals to be stronger and smarter. But hopefully this will not be so because then scientists would really be messing around with something that they are not sure about. This could also have huge impacts on the world.

Free Speech -- Liberty Rights Papers Internet Censorship

Free Speech â€Å"Whoever would overthrow the liberty of a nation must begin by subduing the freeness of speech.† These words were spoken by Benjamin Franklin, one of our nation’s founding fathers, when the United States was still a newly independent country. Free speech, which is defined as the right to express any opinion in public without censorship or restraint by the government, is a subject that is still present in the minds of many people today. At one extreme of the spectrum is a group of folks that do not care the slightest bit about free speech issues and at another end is a group of people who will vehemently fight to protect their right to free speech. In a middle ground, like most peoples’ stance, lay a large group of individuals who only take notice and take action regarding such issues when they become personally affected. Only when a person is confronted directly with someone or something that limits their actions or ability to express themselves do they begi n to realize just how much they take the right to free speech for granted. And not only is free speech threatening issues becoming more common today, but the age at which individuals come across these threats to free speech is getting even younger. It is starting quite early for today’s children as they are becoming well acquainted with perhaps the most widespread but least recognized threat to our free speech, internet content filters. According to the Computer Professionals for Social Responsibility’s (CPSR) Frequently Asked Questions on filtering, a content filter is one or more pieces of software that work together to prevent users from viewing material found on the Internet and is described by the Electronic Frontier Foundation as a software mechanism for... ...ob at actually restricting access to inappropriate material and rather do a much better job at blocking beneficial resources. First and foremost the issue of government-imposed internet content blocking must be addressed. Once a solution to that has been applied, then the use of filters in general can be tackled. The solution to this can best be summed up by the following quote from the National Research Council’s book, Youth, Pornography, and the Internet, â€Å"Swimming pools can be dangerous for children. To protect them, one can install locks, put up fences, and deploy pool alarms. All these measures are helpful, but by far the most important thing that one can do for one’s children is to teach them to swim.† Once parents address the issues through communication with their children, there will be much less of a need for the â€Å"filtering† software on the market today.

This note presents the mechanical design of the system in question and more experimental findings which support the assumption of the novel model constructed there. Moreover, this note contains first conclusions and preliminary discussions. A system composed of a metallic cylinder filled with pressured air (up to 5 ATM), and a rubber, square sectioned ring, as a seal was Investigated theoretically and experimentally. Under a certain pressure difference (Internal minus atmosphere pressure – p) and external sealing force, the rubber seal is compressed (h) and should prevent air leakage.However, experiments show a continuous, nonlinear decrease in p(t) as a function of time. A few classical (macro) thermodynamic models for predicting p(t), via considering air flow through cracks, have been suggested before, based on [1] but they have failed to describe the profile in question due to the coupled constitutive properties of rubber and a construction that allow the creation of micro- scale â€Å"tunnels† in the rubber-lid interface, through which the air can pass.A novel heuristic model, which assumes a symmetry preserving analogy between the micro-scale air tunnels and the rubber polymer strands is proposed. Thus, polymer equations based on statistical thermodynamics are applied on the alarm streamlines. Using this model, there are four unset parameters whose values are being determined by the experimental profiles, similar to the semi-phenomenological rubber model of Mooney-Rivaling. An excellent correspondence between the model and physical essence of the phenomenon.Many standard trendiest have been tried and failed to describe p(t) accurately, including 3rd order polynomial which has also four parameters. Key-words: – Sealing, Pressure drop, Air leakage, Air-polymer analogy, Polyp-Air, Micro-Macro, Language. Ascribing air flow through cracks are available in [2], [3], but those have to be adjusted to describe air flow through rubber-metal inter face. In the following note we will describe the experiment set mechanical design and the final system configuration itself.Moreover, we will mention some results regarding the experiment. 1 Introduction An air pressure vessel (up to ATM) is composed of a metallic cylinder and a cover, and sealed with a rubber, square sectioned ring, as seen in Fig. L . Under a certain pressure difference (internal minus atmosphere pressure – p) and external sealing force, he rubber seal is compressed (h) and should prevent air leakage. However, experiments show a continuous, nonlinear decrease in p as a function of time for small values of h (up to of the initial vertical dimension – ho).A few classical (macro) thermodynamic models for predicting p(t), by describing air flow through cracks (of heat regenerator for example) , have been previously suggested but they have failed to accurately describe the profile in the following specific setup due to the coupled constitutive property of rubber and a construction that allows the creation of micro-scale â€Å"tunnels† in the rubber-lid interface, through which the air can pass. A few more mathematical and physical models of 2 Experiment Setup 2. Introduction and Targets Consider the axis-symmetric setup where the inner pressure is set to a constant value, which is different from the atmospheric pressure (fig. 1). The â€Å"Force† preventing from the piston to pop up and also causes the rubber seal (black) to be subjected to unsocial compression. Thus, the vertical length – originally ho – decreases to a controlled value h. Once deformed enough, the seal prevents leakage of air from the inside. Note that thanks to the upper airway the outer surface of the seal is subjected to the time measure. . 2. 1 Variables and their measuring methods p – with a computerized pressure gage installed as part of the cylinder.. Ho (free vertical dimension of the rubber sample) – with a microme ter h (current vertical dimension of a rubber sample) – using LIVED that track the displacement of the piston from its free force position. T (time)- by the computer clock. T (the temperature of the gasket or air) – with a thermocouple installed as a part of the cylinder. Only for additional data collecting proposes, not a controlled variable.The main target is to investigate the pressure vs.. Time p(t) profile. The seal's function, is to preserve the pressure difference p=P-Pa between the two gasket sides. We'd like to observe how the magnitude of the initial pressure difference and the controlled deformation influence on the profile. The mechanism of air leakage through the seal is yet to be determined but when diffusion is neglected one can presume that the air flows through the rebuttal interface. Our initial assumption is that air flows through narrow cracks-like interracial passages.The assumption about the diffusion arises from mineral notion about the character istic time of gas diffusion through rubber in various applications, which is much larger than these experiments periods (about 1000 seconds). For example, based on [4], the pressure drop in 1000 seconds via diffusion in an UN-defected aircraft tire having similar pressure difference is 0. 06% at most. There is extensive work on air flow through material cracks. 2. 2. 2 Important Technical Aspects See details in fig. 2 for the following considerations. Deformation needs to be assured.The force is actuated via a fine screw, enables measuring the vertical displacement with a LIVED and control he value to it with satisfying precision (10 microns). The purpose of the center ball is to transfer the pure vertical movement without rotational movement and torsion. Seal eccentricity: the experiment should be designed to assure closing force as uniform as possible, although it'll never be ideal, so it'll be wise to try centering the seal and avoid creating preferable air flow sites due to lack of symmetry in the compression field.In the following setup â€Å"hand tolerance† is satisfying. Starting the â€Å"stopwatch† (time measure): practically, the seal is influenced by the way the pressure and deformation are reached. To overcome this problem, the experiment should be done in a way assuring results independent from the initialization. Experiment was stopped when pressure changes are very small. 2. 2 Course of Experiment Preliminary experiments showed a continuous air flow and pressure drop all along the experiment. The general p(t) profile exhibited â€Å"exponential decay† type of behavior.We shall now briefly describe the experiment variables related issues such as the creation of p(t=O) and h , and the protocol of starting/stopping Force pa 2. 2. 3 The Experiment We measure p as a function of time, and determine owe p(t=O)= pop and h influence this profile. Observe fig. 2 for the actual setup. The first step is deforming the seal. Than, opening the main valve ( not in fig. 2), connected to the supply line, and building the pressure to a desired, stable value (waiting for stabilization is crucial). The secondary valve was then closed and p(t) was than monitored.Figure 1 – Schematic section of the experiment setup. The compressed air is colored with blue. -2- Screw ones on the surface) move finely due to compression and each strand remain attached to its original Junctions. The Junctions are getting closer ND dense and so are the strands in the bulk of the rubber gasket, which were dense enough already to prevent air flow. However, the surface isn't a mosaic of Junctions but more of a blend of Junctions and loose strands – strands connected only to one junction. Had the surface was a lattice of Junctions, the contact mechanic would have been similar to metal-on-metal mechanics.But this is not the case. Due to those loose strands, the surface only embedded with Junctions and between them – an entanglemen t of loose stands, rolled and smeared on the Junctions beneath them, preventing the creation f classic surface contact. In order to understand the air flow mechanism, let's observe hypothetically on a metal-on-metal sealing. Each metal plane has its own surface profile with peaks, valleys and defects where air can flow in and find its way out. The probability of perfect sealing – when one plan's peaks are pressed directly on the other plan's valleys – aspires to zero.Practically, the metal-metal interface always consist paths that the air can use for its escaping. We refer to that situation as â€Å"use of built in paths†. The reason behind the superiority of rebuttal sealing over the metal-metal one is he elasticity and compliance of the rubber. When pressed on the metal surface, the rubber's loose strands and even some of the Junctions and regular strands on the rubber surface fill the valleys of the metal. Since the strands are thin compared to the valley, th ey penetrate the â€Å"built in paths† and force (consider a thick bush in a flowing river).This is the idea behind â€Å"labyrinth† seal -forcing the air to flow in a complicated path in order to reduce pressure leakage. The magnitude of a rubber monomer is about 5 LIVED sail Piston Secondary Valve Figure 2 – the actual setup 2. 3 Preliminary results and Conclusions (t) profile was recorded for different initial pressure differences and rubber deformations. The parameters range is: pop=l [ATM] to 5[ATM], to -0. 2. Preliminary results showed that p(t) graphs were different considerably one form the other for the same initial conditions.It was concluded that the experiment is very sensitive to the rubber gaskets different surface profile over the different specimens. See fig. 4 for details. On the other hand, when repeating the experiment with the same gasket, as long as the experiment is not too long so the rubber won't behave differently due to service, we get similar graphs (fig. 3). Discussion 3. 1 Air Flow The proposed mechanically model of leakage is based on three phases. Phase I includes placing the rubber gasket and deforming it to the set value h. The process is described in figure 5. The polymer macrostructure is composed of strands and Junctions.According to untangled mechanical models [5], the Junctions (at least, the experiment #2,#7 experiment #2 pressure[ATM] 4 3. 5 3 2. 5 2 Figure 3 – 4 experiments with ZEE%. The graphs are similar, with maximum of 0. 2[ATM] pressure difference. The difference is due to inability to reconstruct the same initial conditions and due to service effects.

However, this is not the end of the story. Recall that the rubber strands are rather flexible, given an energetic air Jet it might deform the strands, move them aside, and create a much more convenient path. Where it is practically impossible in metallic sealing, when rubber-metal is noninsured the air can create its own path and not use the â€Å"built in† paths by default. Of course, the strands are like springs – moving them aside require a transform of the air kinetic energy to potential spring energy.So we stay with this trade-off: creating convenient path where the friction loss is minimal, or maybe use the built in paths with significant friction loss but save the energy of the path creation. The answer will be given by the minimum energy principle. The reasonable assumption is when the pressure p is great, the air is energetic and prefer create a convenient path. As long as p decreases, the path becomes more and more curvy. When p is too small, we cannot talk about paths anymore since the air kinetic energy isn't high enough. Alternately, the air molecules start percolate on their way out (still in the interface, not in the bulk).Our model won't deal with that region. Only the regions with flow paths are in our interest. The latter discussion was proved qualitatively. An experiment assuring its results is in its design stages. Phase II of the experiment is the pressure buildup. We open the main valve, letting air to flow from the supply line to the cylinder. The supply line erasure is controlled and thus raising the pressure inside the cylinder. At this phase, air is pumped in and leaks out at the same time but the influx rate is much greater then the leakage rate.When the level of pressure reaches the desired one, and stables, the secondary valve is closed and phase Ill is being executed. In phase Ill, the air flows out through the two planes described in phase I in a manner described above. 3. 2 Rubber Gasket Behavior cyli nder, and that pressure acts on the already deformed gasket as it wants to expend it. Due to the normal forces, a friction force (FRR) avoiding the gasket from expending. Beneath is a figure showing the process form the rubber point of view using forces diagram on a vertical section.Let's assume a standard friction model. After a certain level of pressure is achieved, the friction force FRR reaches its maximum static magnitude, which means that the rubber is entering the dynamic friction stage. While the pressure continue to increase, the rubber starts increasing its average radius, so the radii difference – outer against inner – and the height are decreasing due to incompressibility. Notice that h does not change – the piston is fixed – but the expansion decreases the ignited of the friction force even more. When maximum p is achieved, phase Ill starts.The pressure begins to drop and the rubber enters the static fiction level again. The friction force co ntinues its decrease until finally it changes its direction and grows back to the dynamical level. Afterwards, the rubber begins to decrease its radius -4- until the maximum-static-level friction force is enough to hold the rubber gasket in place. It is more than possible that before releasing the piston, the final average radius is different than the initial. There is also the possibility of small p and a strong enough friction force that succeed in keeping the gasket in place all over the experiment phases.Important conclusion is that the volume which the air fills remains constant at the beginning and at the end of the experiment. That is, the contraction is happening at the middle of the experiment (if present). In order to check the validity of the previous speculative argument, a videotaped experiment was taken. There, one we can see how the rubber expends and contracts with the pressure (in [ATM] at the background), where the movement is in microscope (it was videotaped using a regular camera. The movement is absolutely seen to the naked eye).

Transformational and Transactional Leadership

Transformational and Transactional Leadership Transformational and Transactional Leadership Thomas J. Kenny CRJ-810 Dec 16, 2011 Many styles of leadership exist in the management world. Most of these approaches are very similar to one another. Two very different styles of leadership are the transactional and transformational leadership styles identified by James Burns in 1978. These leadership styles are almost polar opposites of one another, with employees in the transactional leadership style motivated by rewards and benefits, and employees in the transformational style motivated by their charismatic managers.These two leadership styles, though different from each another, can be very effective tools in the world of policing. Transactional leadership represents â€Å"those exchanges in which both the superior and the subordinate influence one another reciprocally so that each derives something of value. †(Yukl, 1981) This style of leadership can be compared to dangling a car rot in front of someone, or giving officers who write the most tickets steady weekends off. Leaders who use this style give their subordinates something they want in exchange for something that the leader wants.The reward system of leadership used by the transactional leader can also involve rewards or values that are not as easily tangible such as trust and respect. Burns(1978) referred to these values as modal values; â€Å"modal values bond leaders to followers in an attempt to actualize the needs of both parties. † These rewards such as trust and respect may still be given out by low level police supervisors who may not have the authority to give out overtime or authorize special days off.While transactional leadership is concerned with increasing production and motivation through a reward based system, transformational leadership is concerned with making the employee want to succeed. Bass & Steidlmeier (1998) describes this difference as: Transformational leadership is p redicated upon the inner dynamics of a freely embraced change of heart in the realm of core values and motivation, upon open-ended intellectual stimulation and a commitment to treating people as ends not mere means.To bring about change, authentic transformational leadership fosters the modal values of honesty, loyalty and fairness and the end values of justice, equality, and human rights. Transformational leadership contains four components: â€Å"idealized influence (attributed or behavioral),inspirational motivation, intellectual stimulation, and individualized consideration. † (Bass, 1985) These four components can be summed up as that of a charismatic leader. Employees will see the qualities of this charismatic leader and try to emulate them.Bass (1985) describes this emulation of charismatic leaders as: If the leadership is transformational, its charisma or idealized influence is envisioning, confident, and sets high standards for emulation. Its inspirational motivation provides followers with challenges and meaning for engaging in shared goals and undertakings. Its intellectual stimulation helps followers to question assumptions and to generate more creative solutions to problems. Its individualized consideration treats each follower as an individual and provides coaching, mentoring and growth opportunities.Transformational leadership can be very effective in the world of policing, where the leadership exists from the top down. Officers who work for a transformational leader in a police department must â€Å"understand the vision of the department’s direction, appreciate the organization’s potential, believe that the goal of improvement is supported by the entire organization, and support the idea that change is needed. † (Bynum, 2008) Transformational Leadership can be very effective due to the fact that its motivational and inspirational effects can be long lasting and felt by every employee in the organization.Transformati onal leadership encourages its members to be more proactive and more productive without any specific direction or a reward in mind other than that it benefit’s the organization as a whole. With transactional leadership, some of the rewards such as better hours or days off can only be enjoyed by a few of the members. A competition to see who can write the most summonses, with the winner getting better days off, may increase production at first.The benefit of weekends off can not be given to everyone though, and usually only those who receive the reward will continue to produce as much. Transformational leadership might have a difficult time succeeding in an organization such as the New York City Police Department. The NYPD was founded in 1845, and therefore is deeply rooted in traditions and norms. Even the most charismatic leader, brought into the NYPD to institute change and a new direction, is going to be met with extreme resistance.Police Officers, who can tend to be very reflexive at times, might not take well to the idea of being self starting, proactive, and productive for their department. This initial resistance by subordinates usually makes the transformational leadership approach a long term solution to a departments problems. Transformational leadership tends to be more effective that transactional leadership, due to the fact that most of the terms in the reward based system of transactional leadership are defined and tangible.The subordinate is expected to produce a certain amount in order to receive a benefit. This can tend to make the employee cease production once they have met the production requirement. Conversely in transformational leadership the employees are motivated not by a reward, but for the good of the organization as a whole. This motivation can lead employees in a transformational leader organization to produce much more than what is expected of them. The fact that the terms of a transactional leadership arrangement are tang ible also makes it effective for a short term production problem.A precinct with an influx of burglaries, might offer an extra day off to the next officer who makes a burglary arrest. While in the long run they would want the officer to always be vigilant for burglary arrests, the added benefit of a day off will have additional motivational effects. Transformational leadership is most often effective in organizations that have a need for change, or that have undergone a recent crisis. Transformational leaders tend to have uniting qualities, which can bring an organization out of mediocrity.Adolf Hitler, who was a tremendously charismatic transformational leader, was able to bring Germany back from the brink of total collapse and financial ruin that it was in following World War I. Transformational and transactional leadership can be two of the most effective styles of leadership in policing. By using the transformational leadership style, police managers can foster an group of proac tive and motivated police officers, who want to achieve greater results for the good of the team.By using the transactional leadership approach, they can achieve great results exchanging rewards and benefits with subordinates for increased production. Using a combination of these two approaches to police leadership should lead to great success. References Bass, B. , & Steidlmeier, P. (1998).

Learn How to Use the French Preposition Par

Learn How to Use the French Preposition Par The French preposition par means through, by, or per in English. It is used to indicate the manner in which something is done, the reason behind an event, the direction something moves, or the amount of something per some unit of measurement. In everyday conversation, you might use par when giving directions to someone or to describe how an event occurred. Examples of Par Je suis sortie par la porte.I left through/by the door.Jai appris la verità © par hasard.I learned the truth by accident.Il la obtenu par la force.He obtained it by force.Je lai envoyà © par la poste.I sent it through the mail.Il a jetà © les dà ©chets par la fenà ªtre.He threw the garbage though/out the window.Il gagne 500 euros par semaine.He earns 500 euros per week.Par is often used to introduce the agent in the passive voice:Ce livre, à ©crit par Voltaire...This book, written by Voltaire...La tasse a à ©tà © cassà ©e par un chien.The cup was broken by a dog. Verbs With Par As with prepositions in English, there are some instances when a verb will also require using par in sentence construction. Some of the most common French verbs are: arriver  par  Ã‚  Ã‚  to succeed through/bycommencer  par  Ã‚  infinitive  Ã‚  Ã‚  to  begin by ___-ingfaire  par  (la pitià ©,  lamour)  Ã‚  Ã‚  to do out of (pity, love)finir  par   infinitive  Ã‚  Ã‚  to end up ___-ing / to finally do somethinghabiter  par  ici  Ã‚  Ã‚  to live around herejurer  par  Ã‚  Ã‚  to swear byobtenir  quelque  chose par  Ã‚  Ã‚  to obtain something byprendre  quelquun  par  (la main)  Ã‚  Ã‚  to take someone by (the hand)ressembler  par  Ã‚  Ã‚  to resemble due tosortir  par  (la fenà ªtre)  Ã‚  Ã‚  to leave by (the window)venir  par  (la cà ´te)  Ã‚  Ã‚  to come along/by (the coast)

The Founding of Rome essays

The Founding of Rome essays Greek and Roman myths were generally based on historical events and were told to explain why something occurred, to teach a moral lesson, or to simply be entertaining. The events were not recorded immediately and the stories about the past changed with time. When myths were formally written down, the writers were essentially writing down history known to them through generations of oral tradition. Over time, the stories evolved to be more interesting or appropriate for the time. Different versions of the stories could have come out as a result. Nonetheless, we can still find historical information in the stories and can learn about the people and events of the past. From what we know, we conclude that the historical background on the founding of Rome adheres to the story of Aeneas and the story of Romulus and Remus. We learn about all the ancestors of Romulus through the story of Aeneas. After the Trojan War, Aeneas went down to Hades with the Sibyl of Cumae. He sought his father, Anchises, for advice on how to start a great city. Anchises showed Aeneas his descendants. According to Edith Hamilton, One by one Anchises pointed them out, and told of the deeds they would do which men would never through all time forget, (Mythology, page 240). These men would become the great leaders of Rome. When Aeneas arrived on the west coast of Italy, he fought in a series of terrible battles to win the hand of Lavinia, daughter of King Latinus. With the help of the Etruscan people, Aeneas defeated the leader of the Rutulians, Turnus. His travels were finally over and he married a Latin princess called Lavinia, (Oxford Latin Course: Part 1, page 78). The Trojans took the name of those they conquered, the Latins, and settled along the Mediterranean Sea. The newly established Lavinium was named after its queen, Lavinia.

Business Questions Assessment - Essay Example The market value of an individual’s work determines ones income which dictates the consumption levels. In this system government role is limited and is based on individual innovation and the idea that hard work is rewarded. The businesses will thus exist to make profit and competition is the key element. The entrepreneur takes a great risk with his capital since he requires a full and free availability of information on the buyers and sellers which is not always readily available. However, they have the power to choose on how they want to spend their incomes. In addition to that, the free market economic system leads to the development of monopolies and oligopolies. It influences the production and the distribution of harmful goods and services such as drugs in the economy. It also leads to social income disparities thus widening the gap between the rich and poor. As a result of the major limitations observed in the laissez- fairre system, most countries choose to conduct thei r affairs in a mixed economy. This type of economic system encompasses both the government and privately owned corporates that work together to produce goods for the consumer and solve the economic problems. A mixed economy is considered to be more effective because of the involvement of the government. It is the public sector that will influence the prices of goods to go down through its control measures thus preventing inflation and protecting the consumer. Besides this, the government ensures that income is distributed equally throughout the states. This is achieved through heavy imposition of tax on the rich than on the poor and using such money to construct social amenities throughout the country. The government is also actively involved in the prevention of monopolies by pumping money to support other competing industries as well as obtaining much money from patent owners. Prevention of entry of harmful drugs is also the key role of the government and therefore it ensures that the masses are protected at all costs. The most accepted roles of the government will include the enforcement of property rights, definition of a law system, prohibition of fraud and punishment for prohibited practices (Fernando, 2007, p.297). The state ensures that all goods produced internally are well allocated to generate investments while the private sector is mainly concerned with profit maximization. In a private sector, technology is highly applied and the revenue gained is more than that in the public sector. It may translate to failure to pay taxes or tax evasion or even the engagement in illegal acts. It is therefore the duty of the government to ensure that all taxes are paid and that illegality is exempted. Therefore, most states tend to concentrate on the mixed economy since in such there is a balance between the ownership of resources which translates to a balance in investments. In most and both cases, there is gain to the parties involved and the roles in both corr espond and interact. Question Two Forces of demand and supply determine the price level of goods and services. The intersection of the two marks the equilibrium of both demand and

(GC Instrument Experiment) Determination of Ethanol Concentration in Lab Report

(GC Instrument Experiment) Determination of Ethanol Concentration in Biological Fluids using Gas Chromatography - Lab Report Example The BAC level in all 50 states of the US is set by law at 0.08% w/v a value, which is much higher in comparison to other countries. Other countries have BAC limits of 0.03% w/v or even less (International Center for Alcohol Policies). The use of gas-liquid chromatography in the modern science has eliminated the complex nature of the matrix affecting the analysis of ethanol in blood previously (Jones and Pounder 12). The sample size employed in gas-liquid chromatography is also small hence making the method convenient for analysis of small samples. In gas chromatography, the gaseous mobile phase, which is referred to as the carrier gas, conveys the analyte in the column (Harris 528). Mostly, inert gas such as helium and nitrogen are used as mobile phase while non-polar liquids such as polyethylene glycol can be used as stationary liquid phase (Harris 528). Separation is founded on the dispersal of the analytes between the mobile and stationary phases. The analyte concentration in the gas phase affects its elution since high analyte concentration means more time is spent in the mobile phase as well as the stationary phase (Colin 19). Short analysis time and high precision make it a method of choice. A comparison between flame ionization detectors (FID) and electron capture detectors (ECD) shows that FIDs are highly sensitive to almost all organic compounds, have a wide linear response range that surpasses 107, have low maintenance requirements and are less expensive to acquire and operate compared to ECDs (Harris 543). Five ethanol standards were prepared in a 20 mL gas-tight vial by mixing ca. 0.5% w/w ethanol and ca. 0.5% w/w of tert-butanol in water. The table below summarizes the preparation. tert-Butanol was used as the internal standard. A Shimadzu 14A GC with a flame ionization detector was used. Polyethylene glycol was used as the stationary phase, and the column temperature

The business strengths include partnerships with other restaurants and print and online advertisement. However, their weaknesses rely on diversity as they only deal in restaurant industry and have not considered exploration possibilities. Registration Express refers to a company that conducts registration of a customer’s vehicle at the Department of Motor Vehicles. The inherent strengths of the company involve its comprehensive techniques, ideas, skills, and knowledge relating to the varied requirements for vehicle registration at the Department of Motor Vehicles (DMV). Besides, the company has long lasting intimate relationship with majority of the employees at DMV who willingly assist them. The main weakness of the company remains that it specifically advertises its services only online via social media including Facebook. Moreover, the company remains entirely dependent on the inherent regulations outlined by DMV.

Written Review - Essay Example On the contrary, an association with increased risk of breast cancer has been discovered. HRT could still be used for post-menopause syndromes. Nevertheless, it should not be used as primary prevention for CVDs and bone density diseases. Women’s health is considered to be one of the most crucial medical topics today. Such is why treatments of post menopausal conditions of women continue to be a topic largely investigated. Hormone replacement therapy (HRT) is noted to be widely used among the more developed countries (Nelson, 2008). In the United States, about one third of their population of women report to be users of HRT (Sharma, 2003). In this paper, the author aims to present the advantages and disadvantages of HRT. A review of 3 scientific medical journals will be presented and thoroughly appraised for its validity and reliability. The author hopes that by doing such, a clearer understanding of the benefits and risks of HRT will be achieved. According to Sharma (2003), hormone replacement therapy is widely used by women today because of its ability to treat symptoms of menopause and the chronic conditions associated with it. In his paper, Hormone Replacement Therapy in Menopause: Current concerns and considerations (Sharma, 2003), he launched into an in-depth critical analysis of past studies concerning HRT. His methodology involved a highly specific Medline research for papers written and submitted in the years 1997 to 2003. Only those written in the English language and have an abstract readily available were included in his study (Sharma, 2003). The specific key words used for his study involved hormone replacement therapy, estrogen replacement therapy, menopause and hormone replacement. He was also very thorough and set a criterion in which he would only include materials that are original. According to Sharma (2003) the use of HRT has a strong correlated effect on vasomotor symptoms.

John Lockes Philosophy Of Education Philosophy Essay

John Lockes Philosophy Of Education Philosophy Essay All the objects of the understanding are described as ideas, and ideas are spoken of as being in the mind. Lockes first problem, therefore, is to trace the origin and history of ideas, and the way in which the understanding operates upon them, in order that he may be able to see what knowledge is and how far it reaches. In the first book of the Essay, on the subject of innate ideas, Locke points to the variety of human experience, and to the difficulty of forming general and abstract ideas, and he ridicules the view that any such ideas can be antecedent to experience. All the parts of our knowledge, he insists, have the same rank and the same history regarding their origin in experience. All our ideas, he says, come from experience. The mind has no innate ideas, but it has innate faculties: it perceives, remembers, and combines the ideas that come to it from without; it also desires, deliberates, and wills; and these mental activities are themselves the source of a new class of ideas. Experience is therefore twofold. Our observation may be employed either about external sensible objects, or about the internal operations of our minds. The former is the source of most of the ideas which we have, and, as it depends wholly upon our senses, is called sensation. John Locke was a great education on several counts. In an immediate sense he was himself a practitioner and publicist of good education. This writing assignment is concerned with his biography, his philosophy of education, his advice to parents on the upbringing of their children, his philosophy of curriculum. Biography Lockes father, who was also named John Locke, was a country lawyer and clerk to the Justices of the Peace in Chew Magna, who had served as a captain of cavalry for the Parliamentarian forces during the early part of the English Civil War. His mother, Agnes Keene, was a tanners daughter and reputed to be very beautiful. Both parents were Puritans. Locke was born on 29 August 1632, in a small thatched cottage by the church in Wrington, Somerset, about twelve miles from Bristol. He was baptized the same day. In 1647, Locke was sent to the prestigious Westminster School in London under the sponsorship of Alexander Popham, a member of Parliament and former commander of the younger Lockes father. After completing his studies there, he was admitted to Christ Church, Oxford. Locke was awarded a bachelors degree in 1656 and a masters degree in 1658. He obtained a bachelor of medicine in 1674, having studied medicine extensively during his time at Oxford and worked with such noted scientists and thinkers as Robert Boyle, Thomas Willis, Robert Hooke and Richard Lower. Locke fled to the Netherlands in 1683, under strong suspicion of involvement in the Rye House Plot, although there is little evidence to suggest that he was directly involved in the scheme. In the Netherlands, Locke had time to return to his writing, spending a great deal of time re-working the Essay and composing the Letter on Toleration. Locke did not return home until after the Glorious Revolution. Locke accompanied William of Oranges wife back to England in 1688. The bulk of Lockes publishing took place upon his return from exile   his aforementioned Essay Concerning Human Understanding, the Two Treatises of Civil Government and A Letter Concerning Toleration all appearing in quick succession. He died in 28 October 1704, and is buried in the churchyard of the village of High Laver east of Harlow in Essex, where he had lived in the household of Sir Francis Masham since 1691. Locke never married nor had children. Philosophy of Education Although the Thoughts was most immediately concerned with education, by far the most important of Lockes writings, and one which had great significance for education, was the Essay concerning human understanding. Locke abandoned the attempt to make two unlike things influence each other. He begins his thinking with the thesis that the mind is a sort of blank tablet upon which the world of matter writes by means of sensations. This mind does not have innate or inborn ideas, but it does have the power to arrange impressions in such a way as to produce a consistent system of thoughts. Mind and body, for Locke, exist as real things, but they interact. Bodies act upon the mind and produce sensations. Ideas or perceptions of some of qualities of external objects are accurate copies of qualities that actually reside in the objects, Locke said. This is what he means. Think of a basketball. It has a certain size, shape, and weight, and when we look at and handle the ball, our sensory apparatus provides us with accurate pictures or images or ideas or perceptions of these primary qualities, as Locke called them. Lockes theory: According to Locke, when we say, we are looking at an external object, what we are really doing is attending to the perceptions or ideas of the object in our mind. Some of these perceptions, such as those of a basketballs size and shape, accurately represent qualities in the object itself. Other perceptions, such as those of the basketballs color do not represent anything in the object. Lockes purpose was to examine the nature and extent of human knowledge and the degree of assent should be given to any proposition. Lockes alternative image of the mind as a white paper void of all characters (Essay, 2.1.2) has often been interpreted as meaning that all human beings start as equals. Locke did not believe this; on the contrary, he was conscious that the differing personalities and mental and physical capacities of individuals were to some extent a product of nature rather of nature. How was knowledge acquired? How might men come to universal agreement? To this I answer, in one word, from experience (Essay, 2.1.2). But experience itself, gained via the senses, was not sufficient of itself for knowledge. That also required the active agency of mind upon such experience. Follow a child from its birth and observe the alterations that time makes, and you should find, as the mind by the senses comes more and more to be furnished with ideas, it comes to be more and more awake; thinks more, the more it has matter to think upon. After some time it begins to know the objects, which being most familiar with it, have made lasting impressions. Thus it comes, by degrees, to know the persons it daily converses with, and distinguishes them from strangers; which are instances and effects of its coming to retain and distinguish the ideas the senses convey to it (Essay, 2.1.22). The senses at first let in particular ideas, and furnish this yet empty cabinet and the mind by degrees growing familiar with some of them, they are lodged in the memory, and names got to them. Afterwards the mind, proceeding further, abstracts them, and by degree learns the use of general names. In this manner the mind comes to be furnished with ideas and language, the materials about which to exercise its discursive faculty. And the use of reason becomes daily more visible, as these materials that give it employment increase (Essay, 1.2.15). It must be admitted that Lockes derivation of all ideas ultimately from experience is not without its difficulties. Though, for Locke, experience embraced both sensation and reflection, clearly there are substantial qualitative differences between the simple sensations of infants, and the complex and abstract reflections of the mature adult mind. One way of attempting to resolve such difficulties is to recognize that Locke envisaged ideas of different types. Parents and children His medical knowledge contributed to a concern for the physical, as well as the mental and spiritual, well-being of children. He was not only a founder of empirical thought, with all that meant for ways of learning, but he also may be counted as a pioneer of scientific psychology. He believed in the importance of observing children, and of tailoring education to their needs and capacities. Thus his views on plenty of open air, exercise and sleep; plain diet, no wine or strong drink, and very little or no physick (Thoughts, s.30) would command general support today, though his advice on toughening the feet by wearing thin or leaky shoes so that gentlemans sons might acquire the ability, if necessary, to go barefoot as the poor do, might seem to be somewhat harsh. (Thought, s. 8). Food for children, according to Locke, should be plain and wholesome, with sugar salt and spices used sparingly. From the body Locke turned to the mind. He believe that parents should personally exercise firm and close authority over their children from an early age, with a view to relaxing this as they grow older. Fear and awe ought to give you the first power over their minds, and love and friendship in riper years to hold it (Thoughts, s.42). Locke criticized the over-indulgence of little children, and abhorred obstinate crying on their part, but had little use of any form of physical chastisement. He advised parents and tutors to their children and to note their dispositions and dislikes: for a child will learn three time as much when he is in tune, as he will with double the time and pains, when he goes awkwardly, or is dragged unwillingly to it (Thoughts, s.74). Toys should be simple and sturdy, possible fashioned by the children themselves, rather than expensive and fragile. The curriculum Locke had an overall view of the curriculum which was coupled with teaching methods. He believed in starting with the plain and simple, and of building, as far as possible, upon childrens existing knowledge, of emphasizing the interconnections and coherence of subjects. Children should be taught to read at the earliest possible age-as soon as they can talk. But the learning should not be irksome; on the contrary, Locke believed that it would be better to lose a whole year rather than to give a child an aversion to learning at this early stage. Locke commented upon how much energy, practice and repetition children happily put into play, and therefore suggested dice and play-things with the letters on them, to teach children the alphabet by playing (Thoughts, s.148). From letters they should proceed to syllables and then to easy and pleasant books, such as Aesops Fables, preferably in an edition which included pictures. Locke advocated the use of pictures of animals with the printed names to them (Thoughts, s.156). In recognition of the difficulties inherent in such essential learning as The Lords Prayer, Creeds and Ten Commandments, Locke recommended that these should be learned not from the printed word but orally and by heart. Locke warned against the use of the Bible as a reading book for children, a most common practice in this day, for what pleasure or encouragement can it be to a child to exercise himself in reading those parts of a book, where he understands nothing? (Thoughts, s. 158). Writing should begin with correct holding of the pen and the copying of large letters from a sheet. Writing would lead naturally to drawing, with due attention to perspective, a most useful skill for those who would engage in travel, so that buildings, machines and other interesting phenomena might be quickly sketched. Locke believed that a good drawing was more useful in conveying an idea to the mind than several pages of written description. Locke also urged the value of shorthand for the purpose of making quick notes. Other subjects which Locke commended for a gentlemans son included geography, arithmetic, astronomy, geometry, chronology, and history, and generally in that order. Lockes influence on contemporary education in Cambodia As we have known that John Locke is a great philosopher so his philosophies influences other countries include Cambodia as well. His education that influences on contemporary in Cambodia is that nowadays in Cambodia kindergarten we use John Lockes education such as: we include pictures and fables to teach students. In these stages, teachers teach students by describing and explaining that why Locke recommended. But what we concern is that some Cambodian teachers usually teach students what they have without giving time to students to practice or do the experiment. Moreover, students themselves rarely use their sensations correctly to know the facts. They usually believe that their teachers teach them. It means that what their teachers teach them they just require knowledge from their teachers. These points we should change the bad habit. So teachers have to teach students to use the senses how to acquire knowledge because Locke said that our knowledge comes from experience through se nsation. On the other hand, some students are poor they cannot eat healthy food so that why it is a little bit different from what Locke has recommended. Locke purpose is that he wants children to eat healthy food so when children have strong health they will study more effective. Conclusion In conclusion, Lockes philosophy is very good because he wants all people to know the facts by using experience through sensations. As we have known, something around us is abstract therefore we need to find the truth and reality. As Locke has mentioned above education is very important for all people. So, not only people in other countries but also people in Cambodia parents have to send their children to study at schools. It is a good reason that children are easy to acquire knowledge when they are children because in this stage John Locke held that at birth the human mind is a blank slate, empty ideas. In contrast, if parents don not send them to study it means that their children will be poor at knowledge. At last, Locke said that the goal of education is the welfare and prosperity of the nation- Locke conceived the nations welfare and prosperity in terms of the personal happiness and social usefulness of its citizens.

Dr. Seuss Report Essay -- essays research papers fc

  Ã‚  Ã‚  Ã‚  Ã‚  Not all children may know his real name, but they do know what they like. And what they like is the author Theodor Geisel, or better known as the beloved Dr. Seuss. During the years of my early childhood I fondly remember my parents reading me the whimsical words of Dr. Seuss. His books were filled with imagination and humor which made them very enjoyable for me to listen to. As I got older I started to read Dr. Seuss books all by myself. All of his books are constructed with simple words that make it easy for children to learn how to read. With the pages full of colourful pictures and very little text his books were never overwhelming for a young reader. The simplicity of his books always encouraged me on my path to learning how to read because I never felt like I had to give up. The themes that can be found within his books may be viewed as nonsensical to some, but to most children they are very amusing. The text that Dr. Seuss uses in all of his books consists of words that are important for all children to have in their early and developing vocabulary. I decided to pick Dr. Seuss for my ISP in this course because I find his writing to be educational and very entertaining at the same.  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  There are many similarities to be found between the books written by Dr. Seuss and my original work . For this project I decided to mimic the writing styles that can be found within The Cat in the Hat and One Fish Two Fish Red Fish Blue Fish, two of his most popular books. In 1954 Life magazine published a report about illiteracy among school children. This article stated that children were bored by the books that were available to them at the beginning reader level. His publisher sent Mr. Geisel a list of 400 words that he thought were important for â€Å"new readers† to learn. Geisel used 220 of the words and wrote the infamous book titled The Cat in the Hat. This book was an instant success among children and parents. While writing my original work for this project I wrote myself a list of 300 words that I thought would be important for new readers to learn. Out of the 220 words that I selected I utilized approximately 125 of them within my book. In the Dr. Seuss book titled One Fish Two Fish Red Fish Blue Fish there is no plot that is carried throughout the entire book. Each page is a ... ... New York: Random House, 1958. Geisel, Theodor.

The visit summary

The story opens with the town of Guellen (which literally means â€Å"excrement†) preparing for the arrival of famed millionairess Claire Zachanassian. The town is In a state of disrepair, and the residents are suffering considerable hardship and poverty. They hope that Claire, a native of the small town, will provide them with much- needed funds. Alfred Ill, the owner of Guellen's general store and the most popular man In town, was Claire's lover when they were young, and agrees with the Mayor that the task of convincing her to make a donation should fall to him.As the town athers at the railway station to prepare for Claire's arrival, they are met with an unexpected surprise when Claire steps off of an earlier train. She Is grand, grotesque, and fantastic, and Is accompanied by two henchmen, her husband, a butler, and two eunuchs, along with a coffin, a caged black panther, and various pieces of luggage. She begins a flirtatious exchange with Ill, and they promptly revlslt t heir old haunts: Petersen's Barn and Konrad's Village Wood. Ill finds her as delightful as ever, though they are both now in their sixties and significantly overweight.Claire draws Ill's attention to her prosthetic leg and artificial hand. After settling into the Golden Apostle Hotel, Claire joins the rest of the town, who have gathered outside for a homecoming celebration. A band plays, gymnasts perform, and the Mayor gives a speech. Claire takes the opportunity to announce that she will make a donation of one million dollars, half for the town and half to be shared among the families. The townspeople are overjoyed, but their happiness is dampened when Claire's Butler steps forward to reveal her condition. The Butler was once the Lord Chief Justice ofGuellen, and had overseen the paternity suit that Claire had brought against Ill in 1910. In the suit, Ill had produced two false witnesses (who have since been transformed into Claire's eunuchs), and the court had ruled in his favor. Ill went on to marry Matilda, who owned the general store, and Claire moved to Hamburg and became a prostitute. She declares to the townspeople that she has come to Guellen to prove that Justice can, indeed, be bought. Her donation is conditional on Ill's death. When the Mayor refuses, the town cheers in support, but Claire states rather minously, â€Å"I'll wait. Ill feels generally confident about his status in the town. However, as time passes, he begins to feel troubled about their growing discontent, and then increasingly fearful as he begins to notice the proliferation of new yellow shoes on the feet of the townsmen, and the fact that everyone seems to be purchasing especially expensive items on credit. He goes to see the Policeman to demand that he arrest Claire for having threatened his life, but the Policeman tells him that the threat is nonsense. Ill then turns to the Mayor, who echoes similar sentiments.Both figures are armed, because Claire's black panther has escaped f rom his cage and is prowling about the town. This only feeds Ill's fear, since â€Å"my black panther† was Claire's pet name for him In their youth. He runs to see the Priest, but the Priest seems to be turning away from him as well, as he effectively Ignores Ill's fears and Instead draws attention to the magnificent new church bell. Slowly, the standard of living in the town rises, even though the townspeople continue to assure Ill that he is safe. Claire then receives the news that her black panther has beenKlllea, ana sne nas a Tuneral song played In Its memory. In an effort to escape, Ill heads to the railway station, but finds that, strangely, the entire town is gathered there. They ask him where he is going, and he says that he is planning to move to Australia. They wish him well, again assuring him that he has nothing to fear in Guellen, but Ill grows increasingly nervous nonetheless. The train arrives, but he decides not to board, believing that someone will stop him anyway. Paralyzed, he collapses in the crowd, crying, â€Å"I'm lost! After some time passes and Claire weds a ew husband in the Guellen Cathedral, the Doctor and the Schoolmaster go to see her and explain that the townspeople have run up considerable debts since her arrival. The Schoolmaster appeals to her sense of humanity and begs her to abandon her desire for vengeance and help the town out of the goodness of her heart. She reveals to them that she already actually owns all of properties in the town, and that she is the reason the businesses have been shut down and caused stagnation and poverty for the citizens.The Doctor and the Schoolmaster are aghast at this revelation. In the meantime, Ill has been pacing the room above the general store, his terror growing as the townspeople buy more and more expensive products on credit. News reporters, having received word of Claire's imminent wedding, are everywhere, and they enter the store to get the scoop on Ill, having heard that he was Claire's lover back in the day. The Schoolmaster, drunk, tries to inform the press about Claire's cruel proposal, but the townspeople stop him. Finally Ill descends the stairs, surprised at the hubbub, but quiet.The reporters clear the room when they hear hat Claire has Just divorced the man she has Just married, and has found a new lover. After the confusion has cleared, the Schoolmaster and Ill have an honest discussion. The Schoolmaster explains that he is certain that Ill will be killed, and admits that he will ultimately Join the ranks of the murderers. Ill calmly states that he has accepted his guilt, and acknowledges that the town's suffering is his fault. The Schoolmaster leaves, and Ill is confronted by the Mayor, who asks whether Ill will accept the town's Judgment at that evening's meeting. Ill says that he will.The Mayor hen suggests that Ill make things easier on everyone and shoot himself, but Ill refuses, insisting that the town must go through the process of act ually Judging and then killing him. Ill goes for a ride in his son's newly-purchased car, accompanied by his wife, Matilda, and his daughter, both of whom are wearing new outfits. As they drive through Konrad's Village Wood, Ill says that he is going to go for a walk through the woods before heading to the town meeting. His family continues on to the movie theater. In the woods, Ill comes across Claire, who is walking with her newest husband.She asks her husband to leave so that she and Ill can speak privately. They reminisce about the past, and make plans for the future. Claire tells Ill that she plans to take his body away in the coffin to a mausoleum in Capri that overlooks the Mediterranean. She also tells Ill that she has never stopped loving him, but that over time her love has grown into something monstrous. The town meeting is flooded with press, and the town publicly announces their acceptance of Claire's donation. They then go through the formality of a vote, which is unan imous, and the Mayor states that they have Ill to thank for their new-found wealth.The press is then ushered out of the auditorium to enjoy refreshments. The doors are locked, and the lights are dimmed. The Priest crosses Ill, and he is killed by the townsmen. Just as a reporter reappears In tne au01torlum, tne Doctor announces tnat II I nas oleo Trom a neart attack. The reporters gather, and declare that Ill has died from Joy. Claire examines the corpse, gives the Mayor his check, and leaves the town with Ill's body in the coffin that she brought with her when she arrived in Guellen. Claire boards the train at the railway station, and the visit comes to an end.

Difference in Metaphysics Between Aristotle and Kant

What is the central difference between metaphysics as Kant conceives it, and metaphysics as Aristotle conceives it? Argue in support of one or the other view. Metaphysics is usually taken to involve both questions of what is existence and what types of things exist; in order to answer either questions, one will find itself using and investigating the concepts of being.Aristotle  proposed the first of these investigations which he called ‘first philosophy’, also known as ‘the science of being’ however overtime his writings came to be best known as ‘Metaphysics’ in which he studied being qua being with a central theme of how substance may be defined as a category of being. Kant who is a nominalist criticized both Aristotelian and therefore realists’ ideas of metaphysics by suggesting that they seek to go beyond the limits of human knowledge.Furthermore Kant argued that the structure of the world as it is in itself is unreachable to us; me taphysicians must be content to explain the structure of our thinking about that world. In this essay I will examine the two main exponents of such a doctrine in favor of realists by looking at the main differences of Metaphysics as Aristotle and Kant conceive it, which is centered on the all important question of whether metaphysics is a science of mind or of being.There have been disagreements between philosophers about the nature of metaphysics; Aristotle sometimes characterizes the discipline as the attempt to identify the first cause or better referred to as the unmoved mover and other times as the very universal science of being qua being. It is however important to remember that both of these characterizations identify one and the same discipline. On the other hand the empiricists and Kant were critical of both Aristotelian and rationalist ideas of metaphysics, by arguing that both disciplines seek to exceed the limits of human knowledge.Kant argued that the structure of the world as it is in itself is inaccessible to us and that metaphysicians must be content to describe the structure of our thinking about that world. Realists such as Plato and Aristotle maintain that for language to even exist there must be some universal quality to phenomenon. To elaborate, human beings do not discuss each object as a completely independent entity to be analyzed but rather draw comparisons to other known objects to compile a series of properties to categorize it.Nominalists, on the other hand, while not denying that humans group things together by virtue of certain qualities, maintain that this is simply a convention of language based on people's perception of them. Just because two objects share the same perceptible quality does not necessarily warrant grouping them together in any real way; it's simply a human way of making sense of reality through the senses. As soon as one asks the most basic questions of ‘what is Aristotelian Metaphysics? What study does A ristotle believe himself to be undertaking in these essays? you find yourself, baffled immediately. ‘Metaphysics’ is in fact a compilation of a number of Aristotle’s writings that later on editors put together. It has a central theme of an inquiry into how substance may be defined as a category of being. Book Gamma appears to start on characterizing something which Aristotle calls ‘the science of being qua being’ and then goes on to a discussion of the principle of non contradiction. â€Å"There is science which investigates being qua being and the attributes which belong to this in virtue of its own† (Warrington, 1956, P116).In order to study being qua being, one has to simply study those qualities which hold of entities in virtue of the fact that they are entities. What sort of attributes are qualities of entities qua being? Aristotle insists on unity or oneness as such a feature, on the grounds that everything – everything which exis ts is one thing. However Aristotle’s characterization of the subject raises a few doubts: why is there a need to restrict logic to entities? Is the word ‘qua’ appropriate? No doubt each entity is one thing but is it one thing qua being, or insofar as it exists?Although book Epsilon is rather brief, it shows a return to the science of being qua being and also passes some remarks on truth. â€Å"If there any immovable substances, then the science which deals with them must be prior, and it must be primary philosophy† (Loux, 2006, p14). This shows that the immoveable substances are divinities. Book Zeta appears to restrict our subject matter in a rather different way: ‘the question which, both now and in the past, is continually posed and continually puzzled over is this: what is being? That is to say, what is substance? This question defines the nature of Aristotle’s inquiries, at least for a large part of the Metaphysics, and it thus offers a f ourth account of the study or science of metaphysics. â€Å"The science of first principles, the study of being qua being, theology, the investigation into substance – four compatible descriptions of the same discipline? Perhaps there is no one discipline which can be identified as Aristotelian Metaphysics? And perhaps this thought should not disturb us: we need only recall that the metaphysics was composed by Andronicus rather than by Aristotle.But the four descriptions do have at least one thing in common: they are dark and obscure† (Ross, 1996, p174). Books Zeta, Eta and Theta, together form the central part of the Metaphysics, with a focus on their general topic ‘substance’: its classification and relation to matter and forms, to actuality and to potentiality, to change and generation. According to Aristotle, there is one kind of being which is in the strictest and fullest sense, substance. What we don’t see in Metaphysics is Aristotle treating the categories as a whole.The substance is the whole thing, including the qualities, relations etc which form its essence and this can exist apart. Secondary substances being universals, cannot according to Aristotle’s own doctrine exist apart, but must be supplemented by the special qualities of their individual members. Substance is prior in definition; in defining a member of any other category you must include the definition of the underlying substance. Substance is prior for knowledge; we know a thing better when we know what is than when we know what quality, quantity or place it has.In this realist point of view substance is evidently being thought of not as the concrete thing but as the essential nature. And this double meaning spreads through Aristotle’s whole treatment of substance. The existence of substance and the distinction between it and other categories is for Aristotle self-evident. Kant on the other hand seems to suggest that the necessity for metaph ysics is a psychological one, arising out of men’s desires which is the main difference between Aristotle and him; however I would argue against Kant that this is not the case and it is a logical necessity.It arises out of the mere pursuit of knowledge thus that pursuit, which we call science, is an attempt to think in a logical and systematic manner. This involves unraveling the presuppositions of our thoughts. Furthermore it involves discovering that some of them are relative presuppositions which have to be justified and that others are absolute presuppositions, which neither stand in need of justification nor can in fact be justified; and a person who has made this discovery is already a metaphysician.Kant intends to defend metaphysic and scientific knowledge by providing an accurate analysis of human reason. His theory is based on his discovery of synthetic a priori knowledge, judgments that are both informative and necessary. However I would argue against this nominalis t point of you as there’s a problem with explaining how much judgment should arise, as well as to give an explanation of their truth.In other words The Critique of Pure Reason argues that the necessary metaphysical principles underlying all hypothetical knowledge originate in the pure forms of feeling and the intellect. Furthermore In Kant’s point of view, there are no universal concepts underlying reality, simply the phenomenon in front of us. Realists, on the other hand, maintain that all things that share the same property — for example, greenness for all things with the color green — are therefore linked by this property. Sharing this property implies possession of the same universal form.Nominalism posits that what is perceived is what exists in reality, whereas realists view a perceived object as the manifestation of a universal concept. Consequently, perception is not a one-to-one process of seeing something as it actually exists, but a synthesis o f the underlying concept and real phenomena. Kant wrote the Critique of Pure Reason not as a piece of constructive metaphysical thinking, but it was placed before the public in order to move away from errors which had obstructed and did obstruct metaphysical thinking.In his preface, he argued that his view of Metaphysics is concerned with God, freedom and immortality; however as well as dealing with these subjects, it also signified an inquiry to which men could never be indifferent and which they would never renounce thus the question was no longer about whether people should have metaphysics or no metaphysics but whether they should have good metaphysics or bad metaphysics. He also argued that metaphysicians were to blame for this state of things and that a sounder metaphysics was not to be looked for until those errors had been cleared away. Kant’s way of accommodating both the Aristotelian and Newtonian world pictures alike- both natural teleology and natural mechanism is to ground both in the necessary possibility of rational human nature. According to Kant, the natural world is an objectively real material world in which human persons actually do exist, and consequently in which human persons must also be possible† (Hanna, 2006, p15). Kant’s point is that if metaphysical knowledge is possible, it will share some of the distinctiveness of logic.For Kant, any science must be based on necessary principles as one would not be able to be certain of what theories are true if scientific principles were only contingent. However unlike logic, which is purely formal, metaphysics has content because it is the science of reality. For Kant, The Laws of logic are not absolute or universal they are in fact left with everything else knowable as phenomenal. ‘Nominalist is true’ and ‘A and Not A, cannot both be true’ are both true statements but only and only because this is the way our subjective minds structure and condition reality.They can never true in the universal and absolute sense without this phenomenological caution. For Kant these statements are not necessarily true (though it may be) outside of phenomenal experience. There is no question that Kant intends his theory of pure concepts to replace Aristotle’s theory of the categories. In his categories, Aristotle identified ten classes as the fundamental ontological types under which all things fall: substance, quantity, quality, relation, place, time, posture, state, action and passion.He thought that things falling under all categories could be subject of essential predications, but only substances can keep their identities while undergoing change in time. In general the categories express metaphysical principles that set limits on meaningful discussions. Kant’s idea of categories differentiated from Aristotle’s in the sense that, he argued rather being empirical, in order for the categories to be successful, they must sho w that the concepts are pure and have originated in understanding rather than sensibility.In addition the list must include only fundamental concepts, and it must be systematic to ensure completeness. Kant believes it is possible to obtain a complete list because pure concepts express functions of the understanding, thus the key to a complete list is to assume that the understanding has one function. It can be argued that this method is an improvement over Aristotle’s who merely conducted an empirical survey of concepts, which can never guarantee the systematic completeness of the list. In Aristotle’s case it is unclear whether he saw it as a doctrine about things and their basic properties or about language and its basic predicates; whereas  Kant  quite explicitly used his categories as features of our way of thinking, and so applied them only to things as they appear to us, not as they really or ultimately are† (Barnes, 1995, p75). In conclusion Aristotle a nd Kant’s metaphysics differentiate in the sense that one is arguing in favor of realism and the other is arguing in favor of Nominalism.Although there is no doubt that both ideas have faults, the account I agree the most with is indeed Aristotle’s conception of metaphysics as it focuses on the logical necessity of metaphysics rather than psychological. The main differences between the two accounts can be seen in their treatment of perception, treatment of universals and treatment of language. Bibliography Ackrill, J. L. 1995. Aristotle.
