Masaccio - Innovator Of Perspective And Illusion Essays

Masaccio - Innovator of Perspective and Illusion Masaccio: Innovator of Perspective and Illusion Considered the greatest Florentine painter of the early 1400s, Masaccio is one of the most important figures of Western Art. Tommaso di ser Giovanni Cassai di Simon Guidi was born in 1401 and nicknamed Masaccio Careless Tom because of his attitude. He was apathetic to things like personal appearance and worldly materials, and was thus careless with his possessions. As a child, he concentrated more on his art instead of himself and what others thought about him. He moved from Castel S. Giovanni di Altura to Florence in 1417 to become a pupil of Masolino di Panicale. There, he helped upon innovations of art. In 1422 and 1424, he enrolled in the guild of St. Luke of Florentine Painters. After becoming jaded at the medieval art, Masaccio wanted to make art more realistic and true to life. He constantly studied the idea of perspective in an effort to make his paintings appear natural. Few paintings can be undoubtedly credited to Masaccio, but these are considered masterpieces nonetheless. His greatest work was done on the frescoes in the Brancacci Chapel of Santa Maria del Carmine in Florence. These frescoes were started by Masolino and ultimately completed by Fillipinno Lippi years after Masaccio's death. This chapel is now a significant monument in the history of art. These frescoes had a tremendous impact on Florentine art thereof, and were used as a basis to teach new artists like Michelangelo and Raphael. It is on these walls that Masaccio created -Expulsion from Eden and The Tribute Money, and many others with Biblical subjects. Probably his most famous, The Tribute Money, gives a superb example of linear perspective, atmospheric perspective, the separation of lines, and the classic color theory. Linear perspective is a mathematical system of fixing objects on a plane of a two dimensional surface. This also involves orthogonals, imaginary lines receding into the distance, horizon line, the horizontal line at the viewer's eye level, and vanishing point, where the orthogonals come together. Atmospheric perspective is slightly different. It creates the illusion of depth through methods like color saturation, brightness angle, and texture angle. The classic color theory is another way of emphasizing space in the painting. The theory says that warm colors appear to advance while cool colors recede. This is why Masaccio painted red and orange-clothed figures with a blue and gray background in The Tribute Money. Painters including Masaccio developed the separation of planes in the 14th century. It is the technique of overlapping planes to create depth by using a foreground, middleground, and background. Perhaps the most mysterious thing about Masaccio is his death. Leaving the chapel unfinished, he left for Rome and died and the young age of twenty seven in 1428. It is speculated that he was poisoned, but there are no certain records of this. He was buried at the church of the Carmine in 1443. His friend, Brunelleschi was very troubled after hearing about this because Masaccio had given him many tips in perspective and architecture. Notwithstanding his early death, Masaccio's creations would still be looked upon as a paragon of illusion for years to come. -Sometimes referred to as the forerunner of Michelangelo, Masaccio was, with Donatello and Brunelleschi, one of the founders of the Florentine Renaissance,- according to Encyclopedia of the Renaissance. Masaccio is essentially remembered because of his imaginative use of perspective, and this originality will place him in the same stratum as Giotto and Michelangelo.

Theoretical dimensions involving criminal behavior Research Paper

Theoretical dimensions involving criminal behavior - Research Paper Example Cultural norms are actions and practices that are well-accepted in society, while deviant actions are those that are not acceptable. All forms of crime are considered deviant. It is not acceptable for a person to break into the house of someone else and take everything. It is not acceptable for a person to randomly kill another person. Thus, deviants, most especially, criminals, need to be punished in order for them to be accepted again into society. Theories on Criminal Behavior One of the sociological theories that were applied to criminal behavior was Durkheim’s concept of anomie. Anomie is the mismatch between a person’s (or a group’s) beliefs and that of the majority. When a feeling of anomie exists, then the two groups can not exist in the presence of the other. One has to give way, usually, the smaller group adapting the norms of the larger group. When the smaller group decides to continue going against the norms, then conflict would occur. The concept of anomie was used by Robert King Merton and other sociologists to develop what they refer to as the Strain Theory. The strain theory states that social structures and norms within society may pressure citizens to commit crime. It follows Durkheim’s study of anomie and suicide. He believed that a person commits suicide due to a feeling of insignificance and alienation. Merton used Durkheim’s views to further explain deviance and criminal behavior. ... et of social relationships in which members of the society or group are variously implicated." Anomie, the state of normlessness, arises when there is "an acute disjunction between the cultural norms and goals and the socially structured capacities of members of the group to act in accord with them." (Merton, 1968) Merton then links all the three concepts and believes that discontinuities between culture and structure cause deviance. Source: Wikipedia.org If Merton’s theory would be applied to the social context at present, an example we can use is the common belief that crimes increase in times of economic crisis. People have certain cultural practices, and these practices are supported by the structure (government and economy). Once the structure breaks down, like in an economic crisis, the people would have to adjust their practices. Those who cannot adjust to the new structure, or those who does not want to adjust, tend to do crimes. It’s like a person who steals mo ney from the bank so that he or she can buy food and other basic needs. Robert Agnew further explained Merton’s theory, believing that a theory should not be tied to social class or culture. He popularized the general strain theory, which focused more on an individual’s immediate social environment. He argued that an individual's actual or anticipated failure to achieve positively valued goals, actual or anticipated removal of positively valued behavior, and actual or anticipated presentation of negative behavior all result in strain. For example, if an individual fails to get the kind of attention that he or she expects from others, then that would cause that individual to feel bad about other people. These situations are more common among children, and if this kind of feeling builds up, then

EU COMPETITION LAW Essay Example | Topics and Well Written Essays - 2500 words

EU COMPETITION LAW - Essay Example For a better understanding, the paper will first approach the legal interpretation of concurrence of wills as provide for in Article 81 of EC. Introduction: Understanding Concurrence of Wills as Per Article 81 of EC The EU competition law does not any distinctions otherwise referred to as formalistic between any two varied forms of collaboration within the provisions of Article 81 of the EC law. One may find reference to this in the case involving Volkswagen v Commission1. The concept of agreement, within the interpretation of this article, on the existence of the concurrence of wills, explores different possibilities of trade and sales relations between two or more parties. The article provides that form in which the concurrence of wills manifests itself remains vital provided it is in utmost good faith by parties involved (Office of Fair Trading, 2010, p. 12). In other words, the article also implies that courts shall construe agreements to mean concurrence of wills. One may also i nterpret the article to understand agreements as to mean existence of a common intention between two or more parties. ... Convergence of interest to promote commerce within the provisions of accepted form of competitions such a mergers and collusions. The EU Article 81 interprets collusion in terms of jurisdiction functions rather than in substantive function. The problem is that collusion, under Article 81, does not hold given that it is never jurisdiction in many cases but substantive. Provisions of Article 101(1) TFEU The Treaty on the Functioning of the European Union, Art 101(1) TFEU, takes any agreements between undertakings, decisions by association of undertakings and concerted practices to mean agreements. For better understanding, the article also takes such agreements to mean Horizontal Corporation. In addition to that, clarification, the article also defines Horizontal Corporation to mean any agreement into which actual competitors or potential competitors enter. The article also covers two companies that deal in the same line of the product, though, in different geographical conditions (Off ice of Fair Trading, 2010, p. 21). For the purposes of Art 101(1) TFEU, one expects the article to assess an agreement between undertakings. This is because an agreement is capable of affecting trade between member states. The article assess whether an agreement has elements of an anti-competitive object on competition. It also assesses whether an agreement an actual or potential restrictive effect on competition. In case a court determines an agreement as restrictive of competition within the provisions and interpretation of Article 101 (1), then Article 101 (3) comes into force. The function of article 101(3) is to assess the extent to which the agreement may provide for pro-competitive advantage over the restrictive nature so determined under Article

Cost Benefit Essay Example | Topics and Well Written Essays - 250 words

Cost Benefit - Essay Example In the case stated, reducing expenditures compared to raising taxes have various repercussions even if both course of action are unpopular. Reducing expenditures meant foregoing the opportunity to serve the people and to provide services that could potentially prevent future problems. For example, health care programs could make the population healthier with an implication of lesser health cost in the future. In the case of education, reducing its expenditures may not be immediately felt but it will undermine the country’s competitiveness in the future because it would mean having less educated workforce. Raising taxes however is unpopular. But it will enable the government to fund its social services such as health and education. Excessive taxation however invites social unrest that could defeat its intent to provide services to the people. The repercussion of high taxation is political as policy makers may lose public support and will no longer win in elections. Ultimately, governments have to balance between increasing taxes and reducing social services. Ideally, taxes should be low and social services should be high but that would not be possible since social services is expenditure and it needs income through taxes to fund it. This explains why social services and taxation should be

Practical Ways Of Promoting Resilience Young People Essay

Practical Ways Of Promoting Resilience Young People Essay Resilience as described by many writers is a complex term and therefore needs to be understood in the context. Resilience is normally sought in the child, family and community (Phillips, G. 2008). As professionals, attending training courses helps us to seek something that may assist us in our understanding of those areas. This keeps us in seeking mood and all the time, we tend to keep attention outside ourselves. When we as practitioners recognise resilience in ourselves, we can them be able to facilitate resiliency, thereby linking theory to practice (Phillips, G. (2008). DEFINING RESILIENCE There are many definitions of resilience by different authors. In this context therefore, resilience is defined by Share and Lowlor (2009: 269) as ability to thrive, mature and increase competences in the face of adverse circumstances. Overall, when loved ones absence or presence remains a mystery, meaning and purpose are essential to finding the health and life. After 9/11, some survivors believed that their loved ones being in the Twin Towers at the time of the attack was predestined or Gods will. Many who believed this continue to trust in God to see them through their travels while they move forward with their lives (Boss, P 2006:97). Some characteristics associated with resilient children include cognitive proficiency (especially intellectual curiosity and problem solving), autonomy, good social skills and internal locus of control (Share and Lowlor (2009: 269). Resilience is the capacity to transcend adversity may be seen as the essential quality with care planning and provision should seek to stimulate as a key outcome of the care offered (Gilligan, R. 1997: 14) It is suppressing how resilient people are despite having experienced high risk situation, such as war, disaster, loss, and adversity during childhood and adolescence (Waaktaar, T. Chrisrtie, H, J. Borge, A. Torgersen, S. 2004: 164). Adult who promote resilience make family and institutional supports available to children. They empower children to become independent, responsible, and empathic at altruistic and to approach people and situation with hope, faith and trust (John, M. 1997: 24). However, adults can help children identify resilience behaviours more easily in themselves and others, such as using vocabulary to reinforce these feeling and beliefs that promote resilience and to guide their own childrens behaviour. Therefore, the greater their opinion for acting in the ways that help children met situation such as crisis in their lives with greater strength and hope John, M 1997: 26). Therefore, the most critical key to resiliency is the ability to hold two opposing ideas at the same time. Whatever part is taken, the search for the meaning is much more difficult when the loss is unclear (Boss, P. 2006: 97). THREE THEORIES OF RESILIENCE (1) The Childs Sense of a Secure Base : The growth of a child is influenced by secure attachments which supply him/her with a reliable secure base (Bowlby 1988). Furthermore, it encourages and renders safe exploration of the childs inner world. A young persons sense of secure base therefore is cultivated by a sense of belonging within supportive social networks, attachment relationships to reliable and responsible people and by routine and structures in their lives (Gilligan, R. 1997: 15-16). However, I HAVE factors is one of the external supports and resources that promote resilience in children according to John, M. (1997: 26-27). I HAVE factors includes: trusting relationships, (parents, other family members, teachers, and friends who love and have the interest and welfare of the child), structures and rules at home, (parents who provides rules and routine expects the child to follow them, for example, the task the child is expected to perform, when the rule is broken, the child is helped to understand what he/she did wrong). Others includes: access to health, education, welfare and security services which is available to the child. (2) The Childs Self Esteem: this is based on persons sense of their own worthiness and competences. Rutter (1990) came up with two types of experience which is important in influencing self esteem in young children and they are, secure and harmonious love relationship, and success in accomplishing tasks by others as central to their interests. Also success in an endeavour which the person values may do much to combat a sense of failure in other spheres of ones life (Rutter, 1990 cited Gilligan, R. 1997:17). Therefore, factors such as I AM are the childs internal and personal strengths. These are feelings, attitudes, and beliefs within the child, for example, a resilient child would say: I am proud of myself: this means the child knows that he/she is an important individual and is proud of who he/she is and what he/she is capable of doing and can achieve. I am autonomous and responsible: the child can do a lot with his/her initiative and be responsible and accountable for his/her acti ons or mistakes. I am filled with hope, faith, and trust: the child knows and believes that he/she has hope and there are people and institution which he/she can trust and have faith in. Finally, the child will realise that he/she is loveable and his/her temperament is appealing, he/she is loving, empathic and altruistic (John, M. 1997: 28). (3) Sense of Self Efficacy: this is a situation were parenting style influences whether a child acquires a sense of internal control with regards to attaining desired outcomes. Some factors which promote childs self efficacy includes the parent / caregiver beliefs in the childs own sense of control, responsiveness, consistency, warmth, praise, support and encouragement to the childs to engage / participate in his/her environment (Sandler et al, 1989 cited Gilligan, R. 1997: 17). Moreover, I CAN factor helps to promote the childs sense of efficacy because; it is the childs social and interpersonal skills. Children acquire these skills by constant interaction with others and those who educate them, for example, a resilient child would say: I can communicate: at this stage, the child expresses thoughts and feelings, also be empathetic towards others. I can solve problem: the child can assess a situation of a problem, finds out what needs to be done to resolve the issues and if help is needed form others. Also I can manage my feelings and impulses; I can gauge the temperature of myself and others, and finally seek trusting relationship (John, M. 1997: 29). PRACTICAL WAYS OF PROMOTING RESILIENCE In promoting resilience, any work with children must be similarly in the contexts of their families, school, communities, and the large society (Grotherg, E, H. 2003: 5) Therefore, as a social care practitioner, it is important to know that we are only able to influence that portion of resilience that is amenable to influence through social experience. We cannot affect the degree of resilience that a person has temperamentally due to what they have inherited through their genes (Gilligan, R 2001: 6). As a Social Worker, we can encourage purposeful contact between the child, the family, and other key adults for the childs past, encourage positive school experience, encourage friendships with peers, actively foster interest, strong social network, involvement and talents in sports, music, hobbies or cultural pursuits, help the child to rehearse, and discuss problem solving and coping skills and strategies. Also, each of these I AM, I HAVE, and I CAN factors suggest numerous actions children, parent / caregiver, and practitioner can take to promote resilience (Gilligan, R. 1997: 18-21) This Scenario was adopted from the International Resilience Project by Grotberg, E, H. (2003: 30) A nine year old boy went out of the house even after his father told him not to go out. The father did not know about this until he realized it was late and the boy was not at home. You will promote resilience if you talk to him when he returns and ask why he broke the rules (I HAVE); if you make clear that his behaviour is not acceptable even with his excuses, and that he is responsible for what he did (I AM); and if you talk with him about what needs to be done to prevent this kind of behaviour in the future (I CAN). He will learn from his experience to use resilience to face this adversity, to learn from it, and to behave in a more responsible way in the future. You do not promote resilience if you yell at him or spank him when he comes home, and accuse him of being a bad boy. Then you make him feel guilty, but resentful, and you have given him a label of bad boy, which will influence his idea of himself in the future. He will have difficulty dealing with a future adverse situation, even one that he creates, because he lacks resilience and none is being promoted.

Euthanasia In The United States :: Free Essay Writer

Euthanasia in the United States Every year two million people die in North America. Chronic illness, such as cancer or heart disease, accounts for two of every three deaths. It is estimated that approximately seventy percent of these people die after a decision is made to forgo life-sustaining treatment (Choice in Dying). In America and all around the world, the ongoing debate is whether patients should have the opportunity to implement this critical alternative of euthanasia. Although controversial, it is imperative that United States citizens are not denied this right to a humane death. Groups in opposition to euthanasia say that patients who yearn to make this decision are neither in a healthy psychological state of mind nor have the God-willing right to do so. These groups feel if euthanasia were to become a publicly accepted option to the terminally ill that physicians, family, and even patients may abuse it. They also strongly support modern end-of-life treatment, known as pall iative care, as a more logical and moral option. Perhaps the strongest belief that euthanasia is wrong comes from those who follow the words of the Bible and believe that every aspect of life belongs to God. The Old Testament records an incident involving King Saul of Israel, who became seriously wounded on the battlefield. Fearing the advancing enemy, Saul took his own sword and tried to fall against it. He cried to a soldier, â€Å"Come and put me out of my misery for I am in terrible pain but life lingers on.† The soldier acted in accordance with the wishes of the king and killed him. The soldier then brought some of Saul’s armor to David and said, â€Å"I killed him, for I knew he couldn’t live.† David ordered the soldier put to death (Eareckson, 111). Those who believe in the Bible clearly see here that, whether a monarch or a common person, mercy killing is perceived as iniquitous in the Lord’s eyes. To see a more recent example of the Cathol ic Church’s disagreement of euthanasia we only have to look back a few years. In 1994, for instance, the Dutch television station IKON’s filming of the death of a man with Lou Gehrig’s disease in a documentary, â€Å"Death on Request,† brought a denunciation from the Vatican (Branegan, 30). Equally important to those supporting the anti-euthanasia cause is the thought of any physician, family member or patient who would abuse this right if given the chance.

hey essays

hey essays Throughout our history cities have often been described to be more advanced than other types of communities. The city lifestyle is also often depicted as a superior lifestyle. For these reasons there is usually a push for urbanization in rural and suburban areas. Rural and countryside areas are often categorized as underdeveloped when compared to the city. The Wizard of Oz is meant to dazzle children with witches and Lions, and to provide warmth with a story of the possible. The story suggests the idea that rural areas tend to suppress ones natural abilities, causing certain people to believe that they dont have certain characteristics, or traits. The Wizard of Oz shows us that its not that we lack these traits, but that we are suppressing them and that we do not know that we possesses them. All of the characteristics that each of these three characters lack, are typical deficiencies of inhabitants of rural areas. In the story, Dorothy meets the characters on her way to the Emerald City. Following commonly associated ideas that the city has everything, the characters Dorothy encounters all decide to accompany her in a quest to fill the void in the lives they believe they have. It is on this quest that it becomes apparent that the Scarecrow, Lion and Tin Man do not lack these items, but in fact have them suppressed deep within them. The Lion is introduced as a fierce animal that tries to attack Dorothy on her path. However, he is immediately uncovered to be a coward. The Lion is the ironic choice of being a coward, as he is supposed to be a bully. Seeing as how no one has ever tried to challenge his authority, he believes he would run away in fear if anyone ever did, much like real bullies do. However as the story progresses we see that the Lion isnt the coward he believes he is, as he often shows immense courage in the face of great danger. There are many times throughout ...

Electrochemistry Calculations Using the Nernst Equation

Electrochemistry Calculations Using the Nernst Equation The Nernst equation is used to calculate the voltage of an electrochemical cell or to find the concentration of one of the components of the cell. The Nernst Equation The Nernst equation relates the equilibrium cell potential (also called the Nernst potential) to its concentration gradient across a membrane. An electric potential will form if there is a concentration gradient for the ion across the membrane and if selective ions channels exist so that the ion can cross the membrane. The relation is affected by temperature and whether the membrane is more permeable to one ion over others. The equation may be written: Ecell E0cell - (RT/nF)lnQ Ecell cell potential under nonstandard conditions (V)E0cell cell potential under standard conditionsR gas constant, which is 8.31 (volt-coulomb)/(mol-K)T temperature (K)n number of moles of electrons exchanged in the electrochemical reaction (mol)F Faradays constant, 96500 coulombs/molQ reaction quotient, which is the equilibrium expression with initial concentrations rather than equilibrium concentrations Sometimes it is helpful to express the Nernst equation differently: Ecell E0cell - (2.303*RT/nF)logQ at 298K, Ecell E0cell - (0.0591 V/n)log Q Nernst Equation Example A zinc electrode is submerged in an acidic 0.80 M Zn2 solution which is connected by a salt bridge to a 1.30 M Ag solution containing a silver electrode. Determine the initial voltage of the cell at 298K. Unless youve done some serious memorizing, youll need to consult the standard reduction potential table, which will give you the following information: E0red: Zn2aq 2e- → Zns -0.76 V E0red: Agaq e- → Ags 0.80 V Ecell E0cell - (0.0591 V/n)log Q Q [Zn2]/[Ag]2 The reaction proceeds spontaneously so E0 is positive. The only way for that to occur is if Zn is oxidized (0.76 V) and silver is reduced (0.80 V). Once you realize that, you can write the balanced chemical equation for the cell reaction and can calculate E0: Zns → Zn2aq 2e- and E0ox 0.76 V 2Agaq 2e- → 2Ags and E0red 0.80 V which are added together to yield: Zns 2Agaq → Zn2a 2Ags with E0 1.56 V Now, applying the Nernst equation: Q (0.80)/(1.30)2 Q (0.80)/(1.69) Q 0.47 E 1.56 V - (0.0591 / 2)log(0.47) E 1.57 V

Global Warming and other Ecology Issues; The Energy Crunch Essay

Global Warming and other Ecology Issues; The Energy Crunch - Essay Example These gases allow sunlight to penetrate the atmosphere then trap some of the solar energy which heats the earth (Breuer, 1980). It is a delicate balance and because these greenhouse gases have been artificially augmented by man-made sources, more build up in the atmosphere has occurred thus trapping more of the sun’s energy and reflecting less back in to space. This occurrence is causing the earth to warm. Carbon Dioxide (CO2) is the most prevalent of the greenhouse gases. Although deforestation is contributing heavily to the excess of CO2 in the atmosphere, a larger portion is caused by the burning of fossil fuels such as oil and coal. Fossil fuels are burned by factories, vehicles and electricity-producing power plants to name a few sources. Other greenhouse gases include methane, which is released when vegetation is burned during land clearing, during oil exploration activities and the coal-mining process; chlorofluorocarbons (CFCs), which is the substance that cools refrigerators and provides the propulsion in aerosol cans and nitrous oxide (N2O) which is the lesser cause of CO2 (Breuer, 1980). It is generated from both man-made and natural processes. Although warnings about the human generated causes of an enhanced greenhouse effect and the subsequent catastrophic outcomes have been sounded for over 100 years, global warming has only recently become an important political matter. One would have to wonder what enormous problems this will cause not only to people and property but to the health of the global economy as a whole. Entire sections of various countries will be forced to abandon their homes and businesses. The process will be a slow and torturous one. Agriculture activity, land masses and the very air we breathe will suffer a radical change from the effects of global warming. The question before us is, are we stewards of our earth and will we preserve it for future

Research Methods - Essay Example Whilst he acknowledges that legal compliance and laws may provide a correlation to state behaviour and international politics, Waltz feels that is theory that explains them and to this end attempts to reconstruct classic realism through a somewhat scientific approach. Therefore, Waltz’s book seeks to go beyond the classic realist position of politics in terms of state characteristics and state interaction with each other. Therefore Waltz’s central theory of neo-realism in international politics is underpinned by Waltz’s proposition that the system of international politics is inherently dependent on a system of anarchy. This system of anarchy according to Waltz effectively creates the international order of hierarchy, which is further defined by states who are unitary rational actors on the one hand and rational actors on the other. To this end, Waltz’s discussion of the Cold War highlights his propensity towards viewing the international political order from a systemic perspective as opposed to considering the intentions of individual states and human behaviour, which is arguably the inherent weakness of the book in context of contemporary international politics. For example, in focusing on the international politics as a whole state system as opposed to individual state level factors, Waltz avoids assumptions about human nature and morality and power in international politics. Waltz’s neo-realist paradigm proposes that the central factor in international politics is security and whilst gathering power, often results in destructive effects.
