A Marxist Approach to Global Crime

A Marxist Approach to Global Crime Introduction Global crime is one of the most important problems facing the world and most governments have taken steps to deal with it. These form of crime results in enormous costs to the society and the economy. An understanding of the causes of global crime can be helpful in mitigating this detrimental practice.Advertising We will write a custom essay sample on A Marxist Approach to Global Crime specifically for you for only $16.05 $11/page Learn More Criminologists have made use of many theories and approaches to explain crime and propose ways of reducing crime. One such approach, which can be used to provide a better understanding of global crime, is the Marxist approach. This approach emphasizes socio-political as well as economic factors in explaining crime. This paper will apply the Marxist view on crime to global crime and proceed to discuss what this reveals about power, deviance, and social control. Overview of Global Crime Global crimes occur acr oss multiple national borders and organized criminal groups are the main participants in this transnational crime. Crimes that fall under the global crime category include drug trafficking, people smuggling, arms dealing, prostitution rings, and money laundering to name but a few. Global crime is economically driven and most participants seek to make the greatest amount of profit from their criminal activities. Marxists Approach to Global Crime The Marxist approach is derived from the theories of Karl Marx who is best known for his critique of the capitalist system. Marx asserted that the social institutions such as law, politics, and education, in a capitalist society â€Å"legitimize existing class inequalities and maintain the superior position held by the upper classes† (Kendall 2012, p. 175). Capitalism produces haves and have-nots and encourages people to engage in crime and different forms of deviance. While crime was not a central feature of Marxs theory of society, m any academics and researchers have been able to use Marxist theories in the analyses of crime.Advertising Looking for essay on criminology?

The Marxist approach to global crime is based on conflict with class power being of core importance. The relationship between the classes is one of conflict since it is based on the political domination of the labour providing class by the capital owning class. Global crime is encouraged by the capitalistic system that promotes individual achievements at the expense of other members of the society. The capitalistic economic system fosters most of the global crimes by encouraging the exploitation of one group by another and promoting the self-interest of the individuals who engage in these forms of crime. This thought is corroborate d by McGuire and McQuarie (1994) who argue, The competitive nature of capitalist society promotes social conditions that generate individualism and self-interest (p. 261). For example, Corruption of public officials is a necessary component of many global crimes. The Marxist approach suggests that these public officials are corruptible due to the capitalistic mindset that puts individual prosperity ahead of the society good (Zastrow 2009). The Marxist approach focuses on crime as the product of law-enforcement policies (McGuire McQuarie 1994). Law-enforcement policies are responsible for labelling certain global activities as crimes. While society has grown to think of crime as a well-defined phenomenon and have a stereotyped view about who the criminals are, the fact is that criminal offences and crime is not well defined and criminals are diverse. In most cases, global crime seeks to provide people with desired goods and services that cannot be obtained through legal means. Such products include; drugs, fake visas, and weapons to name but a few. In some cases, the ruling class encourages global crime since it provides goods and services which ease the hardships and deflect the energies of the underclass (Spitzer 1975, p. 508). The Marxist approach further notes that there is selective enforcement of laws with regard to global crime.Advertising We will write a custom essay sample on A Marxist Approach to Global Crime specifically for you for only $16.05 $11/page Learn More While the law deals with people smuggling and drug smuggling by small criminal groups harshly, the same activity by powerful crime groups goes on unabated. International arms smuggling done by powerful actors is largely ignored by the police and the courts. The Marxist approach proposes that crime is inevitable since capitalism, which is based on exploitation, causes crime. The approach suggests that crime is the only way through which the poor working class can m ake a living and therefore ensure their survival. This assertion holds true for global crimes that are mostly motivated by economic considerations. People smuggling can trace its origin to the desperation of individuals in developing nations. From this desperation, they are forced to engage the services of people smugglers who take them to countries where they can have better economic prospects. Most participants of global crime come from poor backgrounds and they are incentivised to participate in these crimes in order to afford the luxuries that the capitalistic society promises. Implications of the Marxist Approach to: Power The Marxist approach argues that criminal law protects the interests of the rich and powerful often at the expense of the poor. Those with power are able to use their resources to avoid criminal prosecution and even having their activities labelled as crimes (McGuire McQuarie 1994). In addition to this, the ruling class is in a position to prevent the impl ementation of laws that threaten their self-interest. Kendall (2012) observes how the capitalistic state avoids introducing laws that regulate business activity or impose huge penalties on large corporations. Corporate crimes are the most serious anti-social acts and they affect millions of people worldwide.Advertising Looking for essay on criminology? Let's see if we can help you! Get your first paper with 15% OFF Learn More However, little attention is given to this predatory act and the government is more interested in curbing crimes such as drug trafficking and smuggling; crimes which cost significantly less in terms of money and lives than corporate crime. The Marxist approach points out that the affluent and powerful are able to protect their own interests and shield them from prosecution even when they commit crimes. Jewkes (2004) observes that those in power manipulate the media agenda to harness support for policies that criminalize those with less power in society. The media is able to manipulate reporting to create an impression that the interests of the ruling class are the same as those of the whole nation and violating the ruling class interests poses a threat to the whole nations well being. With regard to global crime, the media mostly ignores crimes done by the rich and powerful with corporate wrongs seldom being reported. The media either ignores the crimes of the powerful or misreprese nts them and consequently, news reporting remains attached to state definitions of crime and criminal law (Jewkes 2004). On the other hand, crimes perpetrated by less powerful actors are given a lot of media attention. This reflects a pervasive bias in the labelling of criminals. The ruling class decides on which activities should be criminalized and the sanctions that to be imposed on the offenders. This criminalization is not uniform and it is done for the convenience of the ruling class. The selective criminalization is best elaborated by the 18th century trade between China and European states. The main product offered by the West to China was opium and when China banned the sale of opium in her territory, Britain retaliated by attacking China and forcing her to open up her ports for trade (Bickers 2011). The European ruling class was able to impose its will due to its economic and political might. Today, the international trade in opium is criminalized by all Western powers sin ce such trade is not in their best interest. The political and economical powers of the country set the agenda for public debate on crime and the implementation of criminal justice. These agendas shape public perceptions of crime and justice. Kendall (2012) suggests that the picture of crime painted by the ruling class is manipulated so that the crimes of the working class and unemployed are over-concentrated on. On the other hand, crimes of the well-educated upper and middle classes are all but ignored. Deviance The Marxist approach views deviance as a function of the capitalist economic system. Deviance according to the Marxist approach is created by social control agencies such as the police and the criminal justice system, which label people as outside the typical law-abiding community. Becker (1963) illustrates that specific behaviour is not in itself deviant or normal and it only becomes so when people start applying labels to it. The individuals who label behaviour as norma l or criminal are therefore responsible for creating the deviance class. Hester (1992) elaborates that the ruling class has economic dominion and from this base, the class erects the legal and political superstructure. Through these institutions, the ruling class imposes its values, ideas, and beliefs that comprise the social consciousness. Deviants are therefore created by the upper class since its economic and political power enables it to make its views heard and enforced. Attributing the label of deviant to an individual or a group makes them outsiders. This increases the level of crime since the label of criminal might last for a lifetime. Once a person is identified as a member of an international smuggling group, his/her chances of engaging in this activity are increased (Zastrow 2009). This phenomenon is explained by the labelling theory, which illustrates that the deviance label makes it likely that a person will join the deviant group or subculture that society assumes he belongs to and consequently engage in further deviant acts. Social Control The ruling class is able to promote a stable society by encouraging conformity and adherence to societal values (Merton 1938). The Marxist approach emphasizes that the alleged societal values are not a reflection of a shared value system but rather the imposition of the ruling class on the rest of the society. While laws purport to be a reflection of value consensus, they are in actual sense an expression of ruling-class ideology imposed on the working class. These laws primarily protect the interests of the ruling class therefore enabling it to keep its power and influence over the lower classes. The Marxist approach declares that criminal sanctions are put in place to protect the property owners and ensure that their ability to generate wealth in future is guaranteed. McGuire and McQuarie (1994) note that the law and the administration of justice views global crime as a serious offence since it threatens those that possess the property. International drug trafficking increases the levels of crime in the cities as drug addicts engage in robbery to finance their addiction or fail to engage in meaningful economic activity since due to the effects of the drugs. Smuggling of counterfeit goods across borders denies rich corporate of their market dominance and therefore decreases their profits. The media is the most potent tool used by the upper class and the socially privileged to exert social control. The media constructs global crime and violence in such a way that it encourages populations to accept increasingly repressive forms of social control all in the name of dealing with global crime (Jewkes 2004). While all classes of the society engage in crime, the types of crime differ and the media predisposes society to focus on the crimes of the lower classes since the higher classes are the ones who control the media apparatus. Conclusion This paper set out to apply the Marxist approach to global crime. It began by documenting that the Marxist approach blames economic factors and social structures for criminal activity. The paper has discussed systematic class bias in the criminal justice system and how power and inequality affect criminal labelling processes. This approach has explained the relationship between crime and the socioeconomic realities of individuals and given insights into labelling. By using the approach, it is clear that capitalism is the root of crime. As such, global crime can only be eradicated by replacing capitalism with an egalitarian society, which does not divide people into classes. Until this is done, the world will continue to be plagued by global crime and the harmful effects it causes in society.

An Overview of Impressionism in Art History

An Overview of Impressionism in Art History Impressionist art is a style of painting that emerged in the mid-to-late 1800s and emphasizes an artists immediate impression of a moment or scene, usually communicated through the use of light and its reflection, short brushstrokes, and separation of colors. Impressionist painters,such as Claude Monet in his Impression: Sunrise and Edgar Degas in Ballet Class, often used modern life as their subject matter and painted quickly and freely, capturing light and movement in a way that had not been tried before.   Key Takeaways: Impressionism Impressionism is a style of painting that was developed in the late 19th century.  The style, methods, and topics of Impressionism rejected previous historical painting, replacing carefully hidden brushstrokes of historical events with visible thick bright colors of modern scenes.  The first exhibition was in 1874, and it was roundly panned by art critics.Key painters include Edgar Degas, Claude Monet, Berthe Morisot, Camille Pissarro, and Pierre-Auguste Renoir. Impressionism: Definition Avenue de LOpà ©ra. Snow Effect. Morning, by Pissarro Camille. Mondadori / Getty Images Although some of the most respected artists of the Western canon were part of the Impressionist movement, the term impressionist was originally intended as a derogatory term, used by art critics who were flatly appalled at this new style of painting. In the mid-1800s, when the Impressionist movement was born, it was commonly accepted that serious artists blended their colors and minimized the appearance of brushstrokes to produce the licked surface preferred by the academic masters. Impressionism, in contrast, featured short, visible strokes- dots, commas, smears, and blobs. The first piece of art to inspire the critical nickname impressionism was Claude Monets 1873 piece Impression: Sunrise, a piece that was presented at the first exhibition in 1874. Conservative painter Joseph Vincent was quoted in a review in increasingly sarcastic ways, calling Monets work not as finished as wallpaper. To call someone an Impressionist in 1874 was an insult, meaning the painter had no skill and lacked the common sense to finish a painting before selling it.   The First Impressionist Exhibition Frà ©dà ©ric Bazille, Bazilles Studio, 1870. Musà ©e dOrsay, Parà ­s (Francia) In 1874, a group of artists who dedicated themselves to this messy style pooled their resources to promote themselves in their own exhibition. The idea was radical. In those days the French art world revolved around the annual Salon, an official exhibition sponsored by the French government through its Acadà ©mie des Beaux-Arts. The group (Claude Monet, Edgar Degas, Pierre-Auguste Renoir, Camille Pissarro, and Berthe Morisot, and a raft of others) called themselves the Anonymous Society of Painters, Sculptors, Engravers, etc. Together they rented exhibition space from the photographer Nadar (a pseudonym of Gaspard-Fà ©lix Tournachon). Nadars studio was in a new building, which was a rather modern edifice; and the entire effect of their efforts caused a sensation. For the average audience, the art looked strange, the exhibition space looked unconventional, and the decision to show their art outside of the Salon or the Academys orbit (and even sell directly off the walls) seemed close to madness. Indeed, these artists pushed the limits of art in the 1870s far beyond the range of acceptable practice. Even in 1879, during the fourth Impressionist Exhibition, the French critic Henry Havard wrote: I confess humbly I do not see nature as they do, never having seen these skies fluffy with pink cotton, these opaque and moirà © waters, this multi-colored foliage. Maybe they do exist. I do not know them.   Impressionism and Modern Life Edgar Degas, The Dance Class, 1874. Mondadori Portfolio Impressionism created a new way of seeing the world. It was a way of observing the city, the suburbs, and the countryside as mirrors of the modernization that each of these artists perceived and wanted to record from their point of view. Modernity, as they knew it, became their subject matter. Mythology, biblical scenes and historical events that had dominated the revered history painting of their era were replaced by subjects of contemporary life, such as cafes and street life in Paris, suburban and rural leisure life outside of Paris, dancers and singers and workmen. The Impressionists attempted to capture the quickly shifting light of natural daylight by painting outdoors (en plein air). They mixed their colors on the canvas rather than their palettes and painted rapidly in wet-on-wet complementary colors made from new synthetic pigments. To achieve the look they wanted, they invented the technique of broken colors, leaving gaps in the top layers to reveal colors below, and abandoning the films and glazes of the older masters for a thick impasto of pure, intense color. In a sense, the spectacle of the street, cabaret or seaside resort became history painting for these stalwart Independents (who also called themselves the Intransigents- the stubborn ones). The Evolution of Post-Impressionism Mary Cassatt, A Cup of Tea, 1879. Corbis/VCG / Getty Images The Impressionists mounted eight shows from 1874 to 1886, although very few of the core artists exhibited in every show. After 1886, the gallery dealers organized solo exhibitions or small group shows, and each artist concentrated on his or her own career. Nevertheless, they remained friends (except for Degas, who stopped talking to Pissarro because he was an anti-Dreyfusard and Pissarro was Jewish). They stayed in touch and protected each other well into old age. Among the original group of 1874, Monet survived the longest. He died in 1926. Some artists who exhibited with the Impressionists in the 1870s and 1880s pushed their art into different directions. They became known as Post-Impressionists: Paul Cà ©zanne, Paul Gauguin, and Georges Seurat, among others. Important Impressionists   Dance at Le Moulin de la Galette, on the Butte-Montmartre.

Discuss the limited circumstances in which a duty of care might be Essay

Discuss the limited circumstances in which a duty of care might be imposed on a defendant for an omission - Essay Example The main reason why courts are reluctant to impose duties to act may be seen in the arguments made in the case of Stovin v. Wise. The court in Stovin found that requiring somebody to act is an invasion of individual freedom. Moreover, the court also found that the duty prevent harm or render assistance to others is one which is ascribed to a wide range of people, so to single out a person for failing to act is unjust, because one person should not be singled out to be held liable if there are a number of people who have the same duty. Moreover, imposing a duty on third parties for omissions is not generally done because of market distortions which might result. This is assuming that an activity should bear its own costs, and if some of these costs are imposed on others, then the activity might appear to be cheaper than it really is. Requiring compensation for negligent conduct reduces this effect. However, there is not this justification to impose liability on a person who is not vol unteering to spend resources on somebody else, therefore that person may not be rewarded. Just as the person is not rewarded, that person also cannot be punished, unless there is a special reason to do so (Stovin v. Wise). That said, there are exceptions to this general rule, which is the subject of this paper, which will examine these exceptions. Moreover, the cases where omissions were not held to be actionable may further illustrate why courts are hesitant to impose liability for omissions. Discussion There are exceptions to the general rule that omissions are not enough to give rise to negligence actions. For instance, if someone undertakes a duty to assume responsibility for somebody else, then the duty of care does arise, and an omission may give rise to a negligence claim. This was established by the case of Barrett v. MOD [1995] 1 WLR 1217. In the Barrett case, the claimant’s husband died after a night of heavy drinking. At some point, a Petty Officer Wells was instru cted to take the claimant’s husband back to the base and look after him. Although the Petty Officer did look after the claimant’s husband, the claimant’s husband was found dead at 2:30 AM. The Barrett court found that the claimant’s husband was responsible only for himself, but when the senior officer assumed responsibility for him, then the duty of care arose, and the senior officer was then responsible to go ahead and give appropriate supervision over the claimant’s husband. Therefore, once he took responsibility, if he did not act, in that he did not go and check on the man, then this omission would give rise to liability. Another example is the well-known case of Stansbie v. Troman [1948] 2 K.B. 48. In this case, a decorator was working on a house and went to buy wallpaper, leaving the door unlocked. Thieves came in and entered while he was away. The decorator was found to be negligent because he had a duty to take reasonable care to guard agai nst thieves entering the dwelling. Therefore, in the Stansbie case, although the ultimate cause of the theft was the positive act of the thief, it was the omission – the failure to lock the door – which made the decorator liable, because he was under the duty of care to make sure that the house was secure before he left. In this case, it was because there was a special relationship between the decorator and the claimant, because there was

Blindness Essay Example | Topics and Well Written Essays - 1000 words

Blindness - Essay Example Some of the causes include infections, injuries, lack of glasses, trauma, etc. Blind students are also taught using various technologies, including Braille and assistive computer technology. These technologies enable students to read and listen to lecture notes, presentations, course materials and other reading materials. Causes of blindness depend on the socioeconomic conditions to which a person is exposed. They include causes that affect the eye directly and those that affect visual processing centres like the brain. In developed economies, the primary causes of blindness include macular degeneration, traumatic injuries and ocular diabetes complications. In developing and underdeveloped nations blindness is caused primarily by infections, glaucoma, lack of glasses, injury, and cataracts. Some of the infections that lead to blindness in underdeveloped countries include onchocerciasis (river blindness), leprosy and trachoma. The herpes simplex is the most common cause of blindness in developed countries. There are also other causes of blindness such as retinopathy, deficiency of vitamin A, diseases affective the retina or optic nerve e.g. stroke, inflammation, eye malignancies, abnormalities of the congenital, hereditary eye diseases, and chemical poisoning. According to Bourne et al (2013), catarac ts and macular degeneration are the leading causes of blindness. Cataracts affect people from developing and underdeveloped world while macular degeneration mainly affects people from developed countries. Blindness can also be caused by amblyopia, or the lazy eye. This refers to the condition in which a child is born with poorer vision in one eye than the other (NIH Medline Plus, 2015). Untreated amblyopia leads to vision loss and blindness. As the child grows, the brain ignores images from the affected eye, leading to loss of vision in that eye as the child enters teenage stage of life. The condition starts when one of the child’s eyes develops a

FePt Nanoparticle Films Under in-situ Applied Magnetic Field

FePt Nanoparticle Films Under in-situ Applied Magnetic Field Synthesis and characteristics of FePt nanoparticle films under in-situ applied magnetic field Mo-Yun Gao, Xu Qian, Ai-Dong Li*, Xiao-Jie Liu, Yan-Qiang Cao, Chen Li, Di Wu Abstract FePt nanoparticle with L10-phase has extremely high magnetocrystalline anisotropy, good chemical stability, and resistance to oxidation, and has been considered as the most promising candidate for untra-high-density magnetic recording media. In this work, in-situ magnetic field was applied during the synthesis of FePt nanoparticles via a chemical solution method. FePt nanoparticle films were prepared by a dropping method. The effect of in-situ applied magnetic field on the structure, morphology and magnetic properties of FePt nanoparticle films was characterized. Under magnetic field as-synthesized FePt nanoparticles are monodispersed and can be self-assembled over larger area by a dropping method. The chemically ordered L10-phase FePt can be obtained after annealing at 700  °C for 60 min in forming gas (7% H2+93% Ar). It is revealed that applied magnetic field during the synthesis of FePt nanoparticles not only significantly improves the nanoparticles’ c-axis preferred orientation with the larger perpendicular c-axis preferred orientation degree D(001) of 3.47, but also benefits the phase transition of FePt nanoparticles from fcc to fct structure during the annealing process. The FePt nanoparticle films synthes ized under magnetic field also shows some magnetic anisotropy. Keywords: L10-phase FePt; Chemical solution synthesis; Applied magnetic field; C-axis oriented; Magnetic anisotropy 1. Introduction With the rapid development of magnetic recording technique, the superparamagnetic effect becomes the bottleneck to further increase magnetic storage density. The ferromagnetic L10 FePt assemblies with face-centered tetragonal (fct) structure has extremely high magnetocrystalline anisotropy, good chemical stability, and resistance to oxidation [1-3], considered as the most promising candidate for ultra-high-density magnetic recording media. Chemical solution method has become an attractive route to obtain FePt nanoparticles (NPs) with the controllable size, well-defined shape, and ordered monolayer assemblies since Sun et al. made great success in preparing monodisperse FePt NPs [4]. Based on this, a lot of studies have been conducted to explore and optimize the synthesis of FePt NPs, such as modifying fabrication methods [5-13], optimizing assembly methods [7,14-21] and fabricating FePt one-dimensional nanorods /nanowires [22-28] and so on. As-prepared fcc-FePt NPs need to be transformed to ferromagnetic fct-FePt, high temperature annealing will produce severe grain growth and particle aggregation, leading to the decrease of the particle positional order [29]. Great efforts have been made to suppress the unfavorable phenomenon upon annealing and worked. For example, element such as Ag [30], Au [31], and Sb [32] with low surface energy is doped into FePt NPs to abstain from the influence of annealing by decreasing the phase transition temperature of FePt. However, one defect is that the phase transition temperature is too high to avoid particle aggregation, another is that the morphology of FePt nanoparticle will become uncontrolled and self-assembled array over large area are destroyed after Sb doping. In addition, the core-shell structure of inorganic substance such as ZnO [33,34], MnO [35], NiO [36] and SiO2 [37] covering on FePt NPs solves the problem of sintering and aggregation of NPs. However, as the thickness and morphology of core-shell structure is uncontrolled and there exists strong magnetic dipole interaction between FePt magnetic NPs, making it difficult for self-assembled of NPs and orderly array over large area fail to form. Recently it reported that nonmagnetic films like Al2O3 deposited by atomic layer deposition (ALD) upon FePt NPs self-assembly array can improve the stability of FePt NPs under high temperature, preventing NPs from sintering and aggregation [38]. Other work like dispersing FePt NPs into the TiO2 substrate by sol-gel is a good way to protect FePt NPs during annealing [39], but element Fe of FePt will be lost in acidic TiO2 sol. In this work, we reported that in-situ magnetic field was applied during the synthesis process of FePt NPs and the dip coating process to form FePt NPs films. The FePt NPs were prepared via chemical reduction of Pt(acac)2 and thermal decomposition of Fe(CO)5 under different magnetic conditions in the presence of oleic acid (OA) and oleylamine (OAm) at 220à ¢Ã¢â‚¬Å¾Ã†â€™. The prepared FePt NPs films were than annealed at 700 à ¢Ã¢â‚¬Å¾Ã†â€™ for 60 min in forming gas (7% H2 + 93% Ar) to form the L10 phase of FePt. It is revealed that applied magnetic field not only significantly improves the c-axis preferred orientation, but also benefits the phase transition of FePt NPs from fcc to fct structure. The FePt NPs thin film synthesized under magnetic field also shows some magnetic anisotropy. Under magnetic field as-synthesized FePt NPs are monodispersed and can be self-assembled over larger area by a dropping method. 2. Experimental 2.1 Synthesis of FePt NPs FePt nanoparticles were synthesized through a standard polyol process with a modified synthetic condition using standard airless procedures under a gentle flow of pure nitrogen (N2) [12,39]. Typically, the FePt nanoparticles were prepared via chemical reduction of Pt(acac)2 and thermal decomposition of Fe(CO)5 under different magnetic conditions in the presence of oleic acid (OA) and oleylamine (OAm) at 220à ¢Ã¢â‚¬Å¾Ã†â€™. In a typical procedure, 0.125 mmol of Pt(acac)2 was mixed with 20 mL of phenyl ether under the gentle nitrogen gas flow. The mixture was heated to 50 °C, and stir until the platinum source dissolved completely in the solvent. After that the mixed solution was heated to 150 °C and 40 ÃŽ ¼L of oleic acid (OA),42.5 ÃŽ ¼L of oleylamine (OAm), and 80 ÃŽ ¼L of Fe(CO)5 were added step by step under different magnetic conditions with continuous stream of nitrogen. After that, the solution was heated up to 220  °C at the rate of 10  °C per minute., and refluxed for 30 min under the nitrogen protection. After the prepared black solution cooling down to the room temperature naturally, 50 ÃŽ ¼L of oleic acid (OA), 50 ÃŽ ¼L of oleylamine (OAm) and absolute ethanol were added into the mixture to a total volume of 80 mL. The black products were then precipitated by centrifugation (8000 r/min for 10 min) and the solution supernatant was discarded. The precipitate was then dissolved in 10 mL of hexane and precipitated again in 40 mL of absolute ethanol by centrifugation. The black FePt NPs were synthesized by repeating the separation process for 2~3 times. The magnetic NPs were dispersed in 6 mL of octane and stored in brown glass bottle under the nitrogen conditions. 2.2 Preparation of FePt NPs films Assembled FePt NPs on the HF-treated n-Si (100) substrates (1.0Ãâ€"1.0 cm2) were prepared by droping a drop of 2 mg/mL FePt solution (FePt NPs dispersed in octane) including a small amount of OA and OAm. As the organic solvent on the surface of FePt NPs was dried under the protection of N2 at room temperature, the FePt NPs were then heated to 120  °C and maintained for 2h in the baking oven to remove the organic solvent completely. In-situ magnetic field was applied in a patr of the samples during the dip coating process to form FePt NP films and another part were in nonmagnetic field for comparison. Three kinds of samples with different external magnetic field applied during the synthesis process and the dip coating process were listed in Table 1. The prepared FePt NP films were than annealed at 700 à ¢Ã¢â‚¬Å¾Ã†â€™ for 60 min in forming gas (7% H2 + 93% Ar) with a rising speed of 5  °C/min to form ordered fct-FePt before characterization. 2.3 Characterization The structure and crystalline phase were characterized by means of X-ray diffraction (XRD, D/max 2000, Rigaku) using Cu KÃŽ ± radiation (ÃŽ » = 1.5406 Ã…) operated at 40 kV and 40 mA. The morphology and microstructure of various samples were characterized using a transmission electron microscopy (TEM, Tecnai G2 F20 S-twin, FEI) operating at 200 kV. The compositions of all samples were analysed by the energy dispersive X-ray spectroscopy (EDS) attached to a field-emission scanning electron microscopy (FESEM, Zeiss). Magnetic properties of the fct-FePt were measured by a superconducting quantum interference device (SQUID, MPMS XL-7, Qauntum Design) with a maximum field of 35 kOe. 3. Results and discussion Figure 1 (a) and (b) show the XRD patterns of unannealed and annealed FePt NPs films under different magnetic conditions. In Fig. 1 (a), the emergence of two broad peak at 40.3 o and 46.9 o of all samples which represent the Bragg peaks (111) and (200) illustrate the fcc-FePt NPs of average grain size of 4.1 nm calculated by Scherrer equation were obtained. It is obvious that in sample 2# and 3#, the peak (200) are stronger and closer to the highest peak (111) where diffraction is most likely to occur compared with sample 1# without magnetic field applied, indicating that in-situ magnetic field applied during the synthesis process exhibit the trend for FePt NPs to align perpendicular to the (100) crystal plane. While magnetic field applied during dip coating process make no obvious effect before anneal via comparing sample 2# with 3#. High temperature annealing make the phase transform from fcc to fct as indicated by the emergence of the Bragg peaks of (001), (110), (002) and (201) a s shown in Fig. 1 (b). The Bragg peak (001) and (002) are much stronger with the magnetic field applied during the synthesis process among which the intensity of peak (001) has been ahead of main peak (111) and peak (002) split from peak (200) are higher than peak (200) apparently. It means that the fct-FePt NPs films with the magnetic field applied during the synthesis process after high temperature annealing exhibit c-axis preferred orientation that is fct-FePt NPs align along the c-axis perpendicular to the surface of films which is the easy axis of magnetization [40]. Magnetic field applied during both during the synthesis process and the dip coating process has slightly improve c-axis preferred orientation, inferior to sample 2#. We define the degree of c-axis preferred orientation D(001) of fct-FePt in direction [001] as follows [41]: D(001)= (I(001)/I(111))measure/(I(001)/I(111))standard where (I(001)/I(111))standard=0.3 is got in diffraction patterns of fct-FePt powder with random orientation, while (I(001)/I(111))measure can be calculated from the XRD patterns of annealed sample 1#, 2# and 3#. Degree of the chemical ordering parameter S was introduced to illustrate the degree of order of FePt NPs films quantificationally. It is defined as follows[42,43]: S2=[1-(c/a)measure]/[1-(c/a)standard] where c and a are the lattice constants for the fct-FePt, evaluated from the (001) and (110) Bragg peaks of the XRD patterns and the axial ratio (c/a)measure for the partially ordered phase can be calculated then. For the fully ordered-phase FePt, (c/a)complete = 0.9657. Some data of samples under different magnetic conditions are listed in Table 2, including unannealedI(200)/I(111), annealed I(001)/I(111), degree of the chemical ordering parameter S and degree of c-axis preferred orientation D(001). It is easily seen from Table 2 that samples 2# and 3# with external magnetic field applied have a certain degree of [200] preferred orientation before anneal, making [001] preferred orientation more obvious after anneal. Comparing the degree of the chemical ordering parameter S of all samples, we can see that applied magnetic field during the synthesis of FePt nanoparticles not only significantly improves the NPs’ c-axis preferred orientation with the larger perpendicular c-axis preferred orientation degree D(001) of 3.47, but also benefits the phase transition of FePt NPs from fcc to fct structure during the annealing process. The reason for obvious c-axis preferred orientation may attribute to the anisotropy induced by external magnetic field during the nucleation of FePt for that applied magnetic field changed the barrier of nucleation in different orientation ,making the ratio I(200)/I(111) bigger in superparamagnetic particles and a-axis orientation enhanced, which is mor e likely to be transformed to c-axis orientation during the process of films formation and high temperature annealing. 4.

Culture Dominated by Males in Literature Essay -- Literary Analysis

How is the protagonist’s relationship with his/her mother the source of their alienation? ‘All that I am or ever hope to be, I owe to my angel Mother’ -Abraham Lincoln.’1 Alienation: a withdrawing or separation of a person, or a person’s affections from an object or position of former attachment2. Alienation is a key theme present in Woman at Point Zero3 and The Metamorphosis4 by Nawaal El Saadawi and Franz Kafka respectively which is accentuated by both authors to describe what the protagonists go through. With the use of diction, imagery, contrast and symbolism, it is seen how the absence of mother in the protagonist’s life in the two books contributes greatly to their alienation. Gregor Samsa, from The Metamorphosis was the sole bread earner of his family, and was brought up in a society where men took charge. When he undergoes his metamorphosis, he cannot stand the fact that his family has to work and he ‘toyed with the idea that next time the door was opened, he would take the family’s affairs in hand’ (111). These thoughts suggest how much Gregor disliked the fact that ‘his mother had to do the cooking’ (96). The connotation of the word ‘toyed’ creates an image of how Mrs. Samsa was unable to act. Gregor’s desire for domination at this point in the novel begins to emerge, as he searches for his new place in the family, which symbolizes his attitude as he is executed from his bread earning position. However, at this point Gregor is unable to do anything and is left contemplating about it. Nawaal El Saadawi shows us how Firdaus, from Woman At Point Zero never shared a normal relationship with her mother in the little time that she lived with her. Firdaus first notices her mother’s disregard when she trie... ... from their mothers decreases as the novel goes on. It is ironic that a figure such as that of a mother who is supposed to shower her children with abundant love under all circumstances shuns away from her children when they need her the most. Nawaal El Saadawi and Franz Kafka portray their characters as people who share unusual bonds with their mothers and how this contributes greatly to their progressing alienation throughout the book.

Play format to influence the audiences feelings Essay

Examine how Arthur miller uses the play format to influence the audiences feelings towards Eddie The play ‘A view from the bridge’ was written in 1955 by Arthur Miller; a man who’s play was heavily influenced by the work and lives in the communities of dockworkers and longshoremen. This play examines individuals, characters like Eddie, and their responsibilities and position in society. In addition, Miller also reveals to the audience a meaningful understanding way of how Eddie thinks, acts and behaves to his surroundings. While doing this, he also portrays a different perspective of what family and Italian culture is like, based on his own past experiences with Italian immigrants. It is this, which dramatizes the themes of conflict, betrayal, love and obsession. The American immigration system at the time was at its peak and due to the ‘American dream’ many were illegal. Arthur Miller’s play was influenced by this immigration system in America as he had heard stories and personal experiences involving illegal immigrants. At first he didn’t act upon this idea, but after visiting Italy it inspired him to write a play influenced by the social, historical and cultural background of these Italian communities. At the beginning of the play Alfieri sets the scene by showing his perspective through a monologue. The language he uses is direct, formal and expressive of what the characters mean. By the end of Alfieri’s first speech Miller uses the dialogue to influence the audience into thinking their interpretation of Eddie Carbonne to be one of the main characters and to be identified as the hero of this particular tradgedy. The opening of the play also highlights Eddie to be seen as a decent and respected member of the community as he and his wife Beatrice were responsible for bringing up Catherine, Beatrice’s niece, when her parents died. This established Eddie as a father figure, which could explain why Rodolpho and Marco came to stay with him when they first arrived in America. The respect earned from this conveyed in many ways, such as Catherine fetching and lighting a cigar for him, and a more important way in terms of status, twice interrupting his wife in mid speech, and putting words into her mouth if anyone asks her about the immigrants in their house:’ Eddie suppose somebody†¦ ‘ ‘I don’t care what the question is. You-don’t-no-nothin’. He is drilling this idea into her head slowly so she understands the importance of not telling anyone about the Marco and Rodolpho. Miller uses this repeated interruption, which happens towards the opening of the play, to show how early on tension is evident in Eddie and Beatrice’s marriage therefore showing Eddie to be considerate. The first characters Miller presents to the audience are Catherine and Eddie. At first we see Eddie to be quite an overprotective father who sees the naivety of Catherine and tries to explain to her the fact that she’s, â€Å"Getting to be a big girl, you got to keep yourself more, can’t be so friendly†. Eddie still sees her as a â€Å"baby† as does not seem to be able to handle the fact that she is growing up and wants to be noticed by boys. Catherine’s character is presented to the audience as happy and confident, but maybe a bit forward. Eddie sees the craving of attention when she is â€Å"walking wavy† like she is selling her body to the opposite sex. Eddie does not like the fact that the boys â€Å"heads are turning†. This conversation takes place early in the first act into the story and already there has been a change in relationship whereby the audience question Eddie being jealous of the younger boys. Catherine is naive about Eddie’s reactions and thinks nothing of it. There is a lot jealousy developing in their relationship between Eddie and Catherine. Eddie becomes upset at the fact that maybe Rodolpho has won over the affection of Catherine and Eddie has been unsuccessful. Eddie retaliates through jealousy by telling Catherine that Rodolpho is using her for an American passport when they are alone. The stage directions influence the audience, as Catherine is â€Å"smiling but tense†. It is as if you can feel the friction in the air. We sympathize with Catherine as she only wants to grow up and Eddie is holding her back and still treating her like a child. Eddie is doing this because he is scared of the fact that Rodolpho is taking his â€Å"baby† away. However, later on in the play, another side of Eddie is shown. When Eddie had finished the phone call to the immigration bureau and is own his way home he bumps into Louis and Mike, they ask him to come bowling but Eddie at this time turns down the offer, as he is feeling guilty. When Eddie is back into the house Miller presents to the audience the development in Eddie and Beatrice’s relationship. Eddie expects Beatrice to respect him and do as he says â€Å"a wife is supposed to believe a husband. † This dialogue highlights Eddie’s character as being very demanding and uncompromising. The final paragraph uses poetic language and Alfieri says it in an emotional tone. Alfieri shows some admiration in his ending speech for Eddie, â€Å"I will love him more than all my sensible clients. † Alfieri admires Eddie as his heart was in the right place and he didn’t settle for half. This last speech influences the audience into thinking that throughout the play Eddie had always been loyal and decent to his family. Eddie Carbonne is a prime example of a tragic hero, as he was an honest man who nurtured and raised an orphan and gave a home to illegal immigrants. He had a fatal flaw, which, combined with other negative characteristics such as stubbornness and selfishness, led to his downfall. His death was an indirect result of his own actions, and he would have stayed alive had he not incestuously loved his niece, and tried to stop then getting married. Eddie allowed himself to be open with his personality as he portrayed his whole character in the play, from kindness to cowardness.

THE CAUSES OF WORLD WAR ONE essays

THE CAUSES OF WORLD WAR ONE essays World War I started in the summer of 1914. Most of the war took place in Europe. The war was long and lasted four years. World War I was unlike any previous wars. New weapons such as machine guns, tanks and poison gas made fighting deadlier than ever. Also, the civilian population was no longer safe from attack by military forces. Submarines changed naval warfare because they could sink ships without warning. Since, fighting was set all across the world they called it the World War. The main cause for the war was the assassination of Archduke Francis Ferdinand and his wife, who was heir to the throne of Austria- Hungary. The person who assassin Archduke was a Serbian nationalist on the morning of June 28, 1914, while he was traveling through Sarajevo. Sarajevo was the capital city of Bosnia and Herzegovina. The main reason why Archduke was assassin was because the Serbians feared that after his rise to the throne he would continue the persecution of Serbs living within the Austro H ungarian Empire. The Serbian terrorist organization, the Black Hand, had trained a small group of teenage operatives to break into Bosnia and carry out assassination of the Archduke. It was also believed that Nationalism, Militarism, and Imperialism were huge war factors for this war. To begin with, Nationalism was becoming a powerful force in Europe so people that had the same culture, language wanted their own country. Consequently, this was a problem to the Austria- Hungary government because they did not want to lose their power and control. In this case, the Slavs in the southern part of the empire were their main concern since they wanted to join up to Serbia. In addition to this, this tension helped people unite with each other, it also this got countries against one another. Nationalism created deep mistrust and even hatred between nations. Militarism is another factor, to understand what Militarism means we should reme...

Health Care Systems of Singapore and United States Essay

Health Care Systems of Singapore and United States - Essay Example The WHO Report revealed that U.S health system spends a higher portion of its Gross Domestic Product than any other country of the 191 countries. The report ranked U.S at position 37 according to its health care performance. Bureau report of 2006 revealed that 15.8 percent of citizens had no insurance cover. This represented an approximate of 47 million people (DeNavas-Walt et al, 2007:27). This paper compares the health care systems of United States and Singapore. It will look at the organisation, funding, regulation, and quality. Organisation The organisation of the health care system in United States and Singapore differs markedly. To start with, the structure of the health care systems in Singapore encourages her citizens to take responsibilities for their well-being. Singapore health care system comprises of both private and public hospitals. The organisation of health care system embraces three central components of the health care that include Medisave, Medishield, and Medifun d. Medislave is a compulsory saving plan while Medishield is a low cost, catastrophic health insurance scheme while Medifund is a welfare scheme. The three accounts augment government’s system of subsidies for health care. ... The polyclinics account 20 percent of the primary health care provision while the private sector captures 80 percent. However, the public health care accounts for 80 percent while that of private health care is 20 percent in the expensive hospital care (Usa, 2009:111). The structure of health care system in United States is very different from that of Singapore. The health system in United States are very fragmented and decentralised. The health care system concentrate on making profits and patients pay for all health care services. Although the government of United States invests many funds in the health care system, the outcomes are dismal. The organisation of health system in United States embraces private and public insurers in the health care system. The health insurance systems include the Medicaid and Medicare (Barr, 2011:14). The Medicare program, which the government of United State oversees, caters for the elderly and disabled people. The payroll taxes and federal revenues and premiums finance the Medicare insurance. On the other hand, Medicaid covers the low-income earners and the disabled. The federal law dictates that Medicaid should insure parents, disabled, poor pregnant women, and the aged people only. This program is under the State and the District of Columbia. This insurance covers about 13 percent of the American people that makes about 20 percent of total health care spending (Barr, 2011:166). In addition to the public Medicare and Medicaid, United States has private insurance system. This cover caters for 58 percent of the American population amounting to 33 percent of the total spending of health expenditure (Niles,

Analytical review on the presentation on women in shakespaeres sonnet Essay

Analytical review on the presentation on women in shakespaeres sonnet 130 - Essay Example "Many critics read this poem as a parody of contemporary love poetry and it certainly has a mocking tone. Some critics suggest that Shakespeare is satirising the conventions in order to mock the Woman." (Raymond, 167) Through description of the woman's physical beauty and her characteristics, Shakespeare affirms his conception of women and, indirectly, challenges the representation of women in the traditional literature and romantic poems. In a reflective analysis of the portrayal of women in literature through various centuries, it becomes lucid that women have been portrayed differently by writers of different ages and there is a note of cynicism by the time of Shakespeare who breaks the conventional image of the mistress in his sonnet 130. Chaucer's Wife of Bath is the stereotype of women during the period, who is a champion of female rights, and there were several other stereotypes of women, by the 16th century, promoted by the courtly love tradition and the emergence of the sonnet and Arcadian idylls.
