La Primavera (or Spring) and The Tree of Death and Life Essay

La Primavera (or Spring) and The Tree of Death and Life - Essay Example Botticelli's masterwork implies poetic allegory embracing the theme of love and a certain philosophical meaning as it depicts the Garden of Hesperides, which I will dwell on in more detail below. The plot of the painting is being developed from right to left. There is an ominous figure with wings and swollen cheeks dressed in a greenish flowing cloak in the upper right corner of the painting. His name is Zephyrus and he is a symbol of the wind. One can see how the trunks of trees bent influenced by the flight of this mysterious figure. A scared nymph named Chloris, to the left from Zephyrus, tries to run away touching another woman on the left as if asking her for protection. But the woman neglects the nymph, who tries hard to flee from the wind on the right from her, and is walking to the bottom of the painting. It must be noted that this woman in a long dress embroidered with flowers, with a thin face that registers no emotion and a wreath on the golden hair is depicted in the afor ementioned Ovid's poem Fasti that Botticelli was inspired with when creating his masterpiece. In Ovid's poem she is referred to as Spring but, as a matter of fact, this woman might as well be the goddess of flowers and plants, Flora. In the Botticelli's painting she had a dress embroidered with red and blue cornflowers, symbols of amiability and good nature, and scattered roses, which was the usual thing for rich Florentine weddings. The wreath around her neck is made of strawberries that symbolize tenderness, chamomile.

The evolving nature of masculine and feminine roles in relationships Research Paper

The evolving nature of masculine and feminine roles in relationships - Research Paper Example Thornton, Axinn, and Xie observe that there are emerging cases where couples prefer cohabitation to legalised marriages based on their personal experiences, circumstances attitudes and family history (Thornton, Axinn, and Xie 36). Masculinity and femininity are socially determined components of gender. They define behaviours and characteristics observable in either male or female beings. Many times masculinity is associated with maleness while femininity is associated with femaleness Masculinity and femininity being a component of gender is a complex issue. According to Lippa, the concepts surrounding the subject of masculinity and femininity transform over time. Some of the factors responsible for these changes include family influences, biological influences, social influences, cultural influences, peer influences and individual feelings and influences. There is proving that parental socialization of boys and girls in interaction with biological predispositions defines how boys and girls interact with their peers. These interactions determine the femininity or masculinity characteristics that children adopt during their development (Lippa 187). There has been a transformation in the social perceptions of what it means to be feminine. Traditionally femininity entails being nice, submissive, unengaged and reliance. Masculinity and femininity determine the interaction among peers. Masculinity and femininity has also been associated with personal interest. According to psychologists individuals who exhibit masculine characteristics tend to show interest in mechanical and scientific subjects whereas individuals exhibiting feminine characteristics enjoy cultural and art related subjects (Lippa 44). Lippa argued that there are arguments that femininity is considered good for men and masculinity is considered good for women. This concept stands to explain the evolving nature of masculinity and femininity into instrumental traits and expressive traits. Instrumental tr aits include independence, dominance, assertiveness, and leadership abilities whereas expressive traits include sympathy, warmth, sensitivity and compassion. The instrumental traits define masculinity whereas the expressive traits define femininity. The instrumental traits explain why there are women who take up huge roles like taking care of the family, pursuing competitive such as managerial positions and politics. Individuals with expressive traits are considered feminine (Lippa 45). Men who possess expressive traits tend conform to feminine roles. Men who possess expressive traits taking up careers that are considered feminine such as nursing, teaching, and art related careers. Men with expressive traits have no problem raising taking care of the family while their women work to provide for the family. Roughgarden states that culture and society are responsible for imposing on individuals the appropriate way of expressing their sexual identity. According to Roughgarden masculini ty and femininity defines appearance, and behaviour humans. Roughgarden states that masculinity and femininity determines how an organism carious out a sexual role. Biologically masculinity and femininity differentiates the the characteristics possessed by males and females. However, Roughgarden points out the cross gender manifestation and behaviour is acceptable (Roughgarden 28). Roughgarden

Comparison of eastern philosphies confucianism and daoism Essay

Comparison of eastern philosphies confucianism and daoism - Essay Example This is achieved through a series of rituals. The key concepts in the philosophy are five, Ren or humanism which is the basic attribute followed by justice, wisdom, faithfulness and ritual action. Rituals are required for developing a just society and in turn contribute to being a humane person. The philosophy accepts natural proclivities of humans and thus a need is felt to cultivate appropriate practices through rituals. There is also due consideration for physical conduct which is affected by emotions, passions and desires for cultivating the mind. Thus there is a need for reflection and study to nurture the philosophical contemplation required of the follower of Confucianism which in turn develops public spirit. Dao is the road, the path, the way. Daoism is a holistic view of life which does not foster practices to influence forces of reality and reorder life, which is seen in Confucianism. Daoism deems that ritualistic practice disturbs the natural flow. Daoism instead emphasizes on practice and developing experience. Change is reality and there is thus no need to reorder it. However this does not entail a philosophy of nothingness. It only implies that there should be no disturbance of nature by humans and natural actions should allow transformation through effortless activation.

Criteria of American Rebels John Reed, Joseph Freeman, and Louis Research Paper

Criteria of American Rebels John Reed, Joseph Freeman, and Louis Fischer Used in the History Evaluation - Research Paper Example The developing stories of World War I, the Mexican Revolution, and the Bolshevik Revolution show the various stages through which the world has evolved before accomplishing its status. Apparently, the universe has been through series of social, economic and political transformations for the longest time since the introduction of the industrial revolution followed by series of inventions and discoveries that have shaped the world to what it is today (John Reed’s Selected Writings 76-158). Many people recognize the contributions of John Reed in the analysis of the Mexican Revolution as well as the happenings of World War I that have influenced international relationships between countries across the globe. Despite the raging debate over the contributions of World War and the infamous Mexican Revolution to the current status, it is important to recognize the views and opinions of the John Reed that have also illuminated understanding of many learners across the globe (John Reedâ €™s Selected Writings 76-158). In particular, Reed focused on the positive and negative aspects of the Mexican Revolution of 1911. He used unique criteria to create a clear and more comprehensible understanding of the Revolution, which has influenced the social, economic, and political dynamics of current Mexico as well as the neighborhood (Reed 63-78). The Americans (USA) did not understand the 1911 Mexico Revolution. However, the revolution found a soft landing in short stories, silent films, and American novels. The novels have particularly displayed a comprehensive analysis of the stages through which the country went through before attaining political, social and economic independence. Today, the United States and Mexico share fundamental similarities, which have immensely helped the process of shaping up an understanding of the relations between the two countries. Stereotypes about Mexico dominated American films during the 20thcentury (Reed 63-78). The first criteria that John Reed used were to examine and analyze whether or not the people of Mexico engaged in the fierce fight for the sake of it or because they wanted things they could not afford through the alternative option.  

Radical And Liberal Theories Of Inequality Essay Example for Free

Radical And Liberal Theories Of Inequality Essay Social inequality (as a general philosophical and social concept including, before all economic inequalities along with the modern racial and gender issues of disparity) has always been a characteristic feature of human society therefore it is not surprising that majority of ancient and contemporary social philosophers are involved into discussion of how the inequality came to be and what can be done to reduce it. As usually there is no single opinion on the issue. There is an attitude that inequality is an ingrained feature of our social structure so any attempts to reduce or eliminate it are self-defeating. Still there is another opinion: inequality emerged on a certain stage of development of human society when one group of people took advantage of all other people and captured the source of welfare – material goods. It is not yet clear which one is true. The problem of social inequality has a long tradition of analysis; at least since the times of Aristotle, the existence of social disparity appeared a key problem for democratic theory and practice. Nowadays several major philosophical paradigms study the nature of inequality, i.e.: conservative, liberal, and radical; each of them has different vision of the problem (Conservative†¦ 2004). We will focus on liberal and radical visions of the problem and contrast their approaches to view the problem. Libertarian approach before all concentrates on freedoms and social rights of individuals as the members of common society. The approach focuses on people and, contrasting radical outlooks of the problem could be described as the â€Å"individualistic† one. Radical approach, speaking critically, is a â€Å"collectivistic† paradigm that put a focus on social classes instead of people. Liberalists, in their turn, stay on the premises that everyone is before all an individual, and that all individuals have inalienable social rights guaranteed by the society (Kidder et al, 2004). The central value of liberalistic theory is, therewith, inborn freedom of people. Liberals believe that people are able to change their social status themselves and become prosperous in this life. Radicals, on the contrary observe people as foredoomed creature who can’t leave the measures of their social class. As a result, they could become equally treated only through revolutionary changes. Capitalists, observing radical philosophy of social inequality, use all resources available to make the rest of the society equal; therewith, capitalists appear the primary enemies of social inequality who victimize the average people. Liberals never expressed such radical ideas; instead they believe that it’s rather the role of capitalists and government to establish a welfare society. The core differences between liberal and radical approaches, comparing and contrasting ideas of Marx (Avineri, 1968) and Weber (1958), lie in their vision of the fundamentals of social inequality. While Marx stayed on the material premises and some objective reasons that people can’t change, Weber believed in people’s rationality and knowledge that help them to achieve social equality themselves. Weber’s ideas of liberalism are close to the vision of people from protestant religion perspective, while Marx’s ideals are, admittedly, closer to orthodox Christianity. The serious difference between radicals and liberals lies in their vision of key aspects of social inequality origin. Radical philosophers develop a theory of social classes where material aspect is considered to be the key one in people’s social inequality. While liberals believe that relatively few people are unequally treated in the modern welfare societies, radical philosophers and Marx (Avineri, 1968) first of all state that the inequality is to be observed in a wider context, first of all as a disparity between major social classes. Marx outlined five social formations; inequality did not exist in the first and the fifth formation. All people were equal during the epoch of Primitive Communism but gradually the situation changed. Asiatic or Ancient formation (slavery), Feudalism and Capitalism – other three formations – were based upon different modes of production and were characterized by great inequalities. Liberals don’t support the idea of social classes in which radical philosopher believe so blindly. Instead, they believe that the roots of social inequality lie simply in unequal share of commonwealth during the previous time periods. This unequal distribution is, as liberal philosophers believe, the principle factor in the emergence of social inequality. One of the first liberal philosophers Jean-Jacques Rousseau (1993; p. 84) exploring the problem of inequality came to the conclusion that it wasn’t a natural state of human beings; instead he claimed that people were born equal but voluntarily bonded themselves into the society that was evil in itself. As a result, apologists of this approach see the problem of emerged inequality as arising from societies where individuals were not listened to or treated equally. Standing on this ground, liberal philosophers criticize unlimited acquisitiveness as sheer greed, and do not agree that the market should be the arbiter of all values. As far as liberalists stay on the principles of equal freedoms and opportunities they criticize the permanent system of welfare distribution amidst the society. The fundamentals of liberal approach to social inequality could be described, in fact, as the civilized and humane ideals where all people possess individual freedom, moral and physical autonomy social equality, a set of inalienable human rights (i.e.: to life, to express own thoughts and opinions, religious worship etc), due process at law), private property, democratic participation etc. Individual rights and freedoms are therewith are at the top of liberals’ value scale. Liberals believe in democracy as the best way of human existence and states’ development and vote for equal opportunities for all people. They, however, don’t support the necessity of regimes’ changes as the radicals’ do. Radical philosophers, in their turn, vote for immediate and rapid changes of the society. At the same time, radical philosophers vote for rapid changes of society’s norms and traditions through revolutions. There lies the major though implicit difference between both approaches as liberals first of all want to fit unequally treated people to the standards of the others, radicals, on the contrary insist that the top of society must be pulled down and treated unequally. As a result, radicals don’t suggest a clear solution of inequality eliminating because in their model one social class shifts another while inequality isn’t reduced at all (the former USSR could serve here a good illustration). Liberals and radicals also differ in the vision of ideal society, while first one support regulated and humane capitalism, radical philosophers believe in socialistic society where are people have equal rights. This idea, however, turned to be utopist one judging from the USSR collapse example. Dislike radical philosophers, liberals observing Kidder (2004) never vote for the rapid and all-round changes in the society in order to reduce or eliminate inequality. Instead, they suggest the remedies for those, who became unequal in this society through no fault of their own. Therewith, liberalism as a philosophical and political system is targeted to defend people from any abuses by authorities or other people. To achieve relative social equality liberals suggest various social programs, labor units, reduction of taxes for those who are in need of such alterations. Liberalists, dislike radical philosophers, believing in the role of society and a state as a self-regulating mechanism that is helpful for every its member. In order to achieve this objective, the government is to regulate somehow market relations to protect public interests. Apologists of liberal approach believe that government can indeed play a constructive role in the society and don’t insist on its elimination as the radicals do. In a word, liberals want both business and government to be more responsible and responsive to the public interest. That’s achieved through corporate social responsibility and governmental regulation of businesses. Radical philosophers and politicians (Kidder, 2004) never presume the idea that a government or a state could abolish social inequality. Instead, only the unequally treated people could do this through revolutionary changes in the society having wiped out a ruling class and capitalists. The language of the radicals tends not to â€Å"convert† but to â€Å"repel† most people. Radicals, therewith, call for some drastic and fundamental changes in the economy including nationalization instead of private property, complete governmental regulation instead of partial intervention and equation of all salaries instead of mixed approach. Do you think American society is open now? Traditionally, American society is believed to be the most free and democratic one in the world. Comparing with the other states, even the democratic ones, we come to the conclusion that American society is quite open nowadays: that mean that all people are born equal and are provided with equal conditions for their life and development. At the same time American as probably no other society could guarantee its people the same financial welfare. Instead, provision of people with equal rights make them responsible for own social and financial development. At the same time, American society is not deprived of several serious drawbacks that slow down building of a completely open society. It’s first of all social discrimination and derogatory stereotypes that dominate over the minds of million Americans; protectionism and some other forms of inequalities that, however, tend to lessen in the modern society.

Crash Human Nature Essay Example for Free

Crash Human Nature Essay * Human nature is The general psychological characteristics, feelings, and behavioural traits of humankind, regarded as shared by all humans. * Crash directed by Paul Haggis presents to us an intertwining story set within the streets of LA, confirming and challenging racial stereotypes and at the same time reflecting the ever existing good and dark side of human nature. * Human nature drives us all to view â€Å"the other† as bad, evil and untrustworthy, it is complex and every man, despite differences holds the underlying values buried deep into our subconsciousness * In the film crash, Haggis has successfully portrayed the truth about human nature through the conventions of dialogue, camera shot and symbolism, confusing us as viewers, but also giving us an intruging insight into the reality of each and every one of us despite differences in race and background. * Haggis has successfully evoked feelings of uneasiness, confusion, anger and empathy at through the making of the film crash. * Human nature drives us to fear the unknown, the â€Å"other† in our eyes is seen as evil and that we should steer away from any communication. It may be in relation to race, ethnicity, age, gender or beliefs but in reality each one of us does not have the ability to fight this automatic discrimination against those who are different. * Haggis has successfully reflected this dark aspect of human nature through the convention of dialogue. * In one scene a Persian man is attempting to purchase a gun from a white American. The salesman calls the man â€Å"osama† and then continues to talk about 9/11, he then is aggressively told to leave the shop. * The white American man displays his fear of â€Å"the other† by racially discriminating him through his dialogue, he has his own racist, stereotypical image of this man in his mind automatically relating him to 9/11 and due to his human nature sees him as â€Å"the other† and as untrustworthy to be in his shop telling him he â€Å"has no right to buy a gun here† * In another scene a Hispanic locksmith is changing a white American couples locks on their door after their car had been hijacked. The American woman makes assumptions that this locksmith is going to sell their key to his â€Å"homies† purely because of the way he looks and his race and demands to get her locks changed again in the morning. * The American woman views the locksmith as â€Å"the other† and due to her human nature she fears him, and does not trust him to be in her house. Her judgement is not on personality or individual traits it is based upon the automatic assumptions she makes about him due to his tattoos, dress sense and skin colour. Little does she know that the Hispanic locksmith was in many eyes the only character in crash seen as completely innocent, but due to her ignorance she believed the opposite. * Through dialogue Haggis has successfully positioned the viewer to feel anger at both of these scenarios and causes us to question our own human nature and our own classification of â€Å"the other†. We are positioned to feel guilt as we feel partly responsible for these racial stereotypes as we too, through our human nature, instinctively stick to our own. * Human nature is complex, values at polar opposites could exsist in the same man, particular beliefs could be compromised and in reality no one can ever truly understand the extent of complexities embedded within each person. * Racsim and nobility can exsist in the same man. Haggis has successfully portrayed this idea of human nature through the narrative conventions of camera shot and dialogue. * In one scene a cop pulls over a black couple, he abuses his power and shows extreme racism seen through the convention of low camera angle while he molests her. * In another scene the same cop shows nobility while is seen rescuing the same black woman he molested, he ironically says things to her such as â€Å"im not going to hurt you† * The camera angle in the first scene is a panning low angle displaying the police officers hand stroking up the womans leg, emphasizing his sickening racist actions. In the second scene the camera angle is a close camera angle focusing on his remorseful worrying facial expression. The shot of the hand in the first scene could represent â€Å"a mans hand† where the shot of his face in the second scene presents him, and therefore suggests that although his racism and dark side of his human nature exsists the good side of his human nature is a representation of his true identity and we begin to question the reasons behind his actions. * These two scenes In the movie crash display to us that humans are extremely complex. A man can live a life full of sin but then commit a noble act just as a man can be a criminal but then save a life. * The concept of human complexities is hard to grasp, an individuals identity can determine why they act a certain way or do certain things. The cop in the film displayed racism due to the fact that a black woman would not help his sick father, but does this excuse particular values and behaviours? * Through the convention of camera angle Haggis has effectively positioned the viewer to feel both disgust and awe at the same man. We begin to question what drives humans to be so complex and we wonder whether it is ever possible for a man to be seen as completely innocent. * Instinctively human natures drives us to protect and stick to our own, just as we repel those who are seen as different. * This universal value embedded inside each and every human is represented by Paul Haggis in the film crash through utlising the narrative convention of symbolism. * Crash follows the story of a Hispanic locksmith and unconditional love of his.

Survey on Spatial Database Systems

Survey on Spatial Database Systems à ¯Ã‚ Ã¢â‚¬ ºÃƒ ¯Ã¢â€š ¬Ã‚  Ãƒ ¯Ã‚ Ã‚  Abstract—In this survey, the term of â€Å"spatial database†, its data models, its data types with implementations, and its management techniques are described with providing at least spatial join methods. Also the storage and query processing algorithms for such databases are surveyed. (Abstract section will be updated with final report) 1.Introduction Various fields need various data types such as character, number, date, time, and image in data base management systems (DBMS). Some other fields need more specialized data types with geometric and geographical attributes. Those needs are satisfied by the spatial data. The Spatial Data is described as data related to time and space [12]. The most noticeable area for spatial data types is two dimensional abstraction of the earth surface [Figure 1]. Other examples are layouts of very large scale integration designs in electronics, 3D designs of biological issues like DNA, and the complicated models of the human brain systems. Figure 1: Spatial Data. (Source: http://www.cubrid.org/blog/dev-platform/20-minutes-to-understanding-spatial-database/ [11]) Spatial database systems can be grouped as followings [1]: Geographical Information Systems (GIS) deal with digitized maps displaying geographic or thematic information. Automated Mapping/Facilities Management (AM/FM) systems which automate the management and maintenance of networks such as power grids or telephone lines. Land Information Systems (LIS) manage information such as Image Processing systems which process remote sensing images acquired by aircraft and satellites. LIS also deal with the details of land parcel ownership. Although the relational DBMS’s have been tried to manage those types of data, they did not meet the requirements properly [12]. Spatial database systems provide advantages in areas such as decision support, administration, transportation scheduling, resource management, environmental monitoring, real-time navigational systems, data quality and integrity enforcement, and impact assessment. The remaining of this draft report is organized as follows: In Section 2, Modeling Spatial Database Systems is explained in detail. In Section 2.1, the characteristics of spatial data types are represented. The relations and related explanations are provided in Section 2.2. The querying and its techniques are represented in Section 2.3. At 2.4, indexing of spatial data is shown. Visualization of spatial data is explained in Section 2.5. Finally, concluding remarks are summarized in Section 3. 2. Modeling SPATIAL DATABASE SYSTEMS Spatial database systems are either the new DBMS or additional features on Relational DBMS’s. It is a DBMS with additional capabilities for handling spatial data and Offers spatial data types in its data model and query language. For modeling such a database system, data types, relations, querying, indexing and visualization steps can be considered different parts of it. 2.1.Data TYPES There are classical data types for all DBMS such as types of chars, types of numbers, date, and time. Spatial data shows the geometric and geographical variables such as point, line, region, polyline, and polygon. The presentation of those can be divided into two main groups [1]. 2.1.1. Objects in space It is a representation of spatial data types such as polygons, lines, polylines etc. Point: As pairs of coordinates in lat/long or some other reference system A point feature is a zero-dimensional cartographic object. It specifies the geometric location and no other meaningful measurement The size of the point may vary, but the area of those symbols is meaningless Four types of points exist: entity point, label point, area point and node Line: Ordered sequence of points connected by straight lines Line features are one dimensional features, despite occupying two-dimensional space. A line segment is the direct connection between two points A line feature is typically represented as a sequence of vectors An Arc is the location of points that are defined by a mathematical function to form a curve Link or edge is the connection between two nodes Areas: As ordered rings of points connected by straight lines to form polygons Area is a two dimensional, bounded and continuous object Interior area is an area not including its boundary Simple polygon consists of an interior area and an outer ring. The boundary does not intersect itself Typically refers to vector polygons, but also relates to pixels and grid cells. 2.1.2.Space It deals with Statement about every point in space such as partitions into states, counties, municipalities etc. (This section will be detailed in final report) 2.2.REALATIONS Spatial relationships are very important in the operations offered by spatial algebras. For instance, it is possible to ask for all objects in a given relationship with a query object, e.g. all objects within an object or intersection points. There are several classes [8, 3, 4]: †¢ Topological relationships †¢ Direction relationships †¢ Metric relationships (This section will be detailed in final report) 2.3.QUERYING Spatial data requires a graphical presentation of results. In addition, SDT values used in queries or graphical input of queries need graphical representations. (This section will be detailed in final report) 2.3.1.Languages Query languages for spatial databases can be used as candidates for the creation of a spatial language. Because of the extra semantic complexity added by spatial dimensions, it is desirable to have features in a spatial query language that go beyond those provided by currently available mainstream relational languages. (This section will be detailed in final report) 2.3.2.Operators There are several types of spatial operators [4] logical relationships, arithmetic, spatial metrics, position, orientation, area, volume, shape, extent, surface, disjunction, intersection, inclusion, neighborhood, and equality. (This section will be detailed in final report) 2.4.INDEXING For all DBMS, fast access to row data depends on the quality of indexing. Complex indexing methods can be used to rapidly locate single or multiple objects in the databases. (This section will be detailed in final report) 2.4.1.Indexing Methods For spatial databases, some indexing techniques such as quadtrees [6], R-Trees [2] are mostly used ones. (This section will be detailed in final report) 2.5.vÄ ±sualÄ ±zatÄ ±on The modern database management systems provide visualization tools to represent spatial data and queries about those data. Browsers, plotters and map displays can be considered as standard tools for spatial database systems. Although some researchers classify the spatial maps as maps showing qualitative, quantitative and composite change, and space-time ratios[9], some researchers made this classification like dance maps, chess maps and change maps to visualize time series data [7].
