Now upon examining reproductions, I recognize that in large part there is a distinction between the linearity in the woman’s hands, as well as in bodily elements. I also recognize the painterly elements in terms of the sfumato effect, specifically in an articulation of the woman’s mouth. One element I disagree with is the mystery surrounding the woman’s expression. While I recognize art critics popularly argued this feature of the painting, I believe that to a degree such perspectives are overblown and the work can be appreciated simply for its power and depth of creation.  Now upon examining reproductions, I recognize that in large part there is a distinction between the linearity in the woman’s hands, as well as in bodily elements.

African americans and the military during WW2 Essay

African americans and the military during WW2 - Essay Example They nurtured great expectations due to their excellent work and war records they possessed. This hope had been carried further as President Wilson declared that the war was being fought â€Å"to make the world safe for democracy†.(President Wilson, World War I) African American soldiers as well as the civilians always recollected or remembered their painful experiences of World War I. They had endured discrimination and segregation in almost all areas and they were not willing to accept these factors once again. So they started raising their voices in protest for which they had to undergo severe punishment in lieu of their attitude. Their hopes and aspirations were dashed to the ground when after the war; discriminatory feelings began to grow against them in leaps and bounds. The Ku Klux Klan was once again revived and gained the support of other anti- African American groups. The Blacks suffered horrendous discrimination and riots and attacks left thousands homeless. Many of the Black writers interviewed some of the black American slaves and received a first hand report of the atrocities meted out to them. Due to segregation of the Black Americans discontentment and the need to take revenge brewed among them. Many organizational groups such as the Brotherhood of Sleeping Car Porters, the NAACP and the National Urban League tried very hard to put an end to segregation of the Black Americans and the discrimination shown to them, but all the efforts undertaken were slow and laborious. The NAACP also worked towards obtaining voting rights and tried hard to dismantle discrimination and segregation by moving the court. They also strived hard to gain laws that were beneficial to the suffering African Americans. The â€Å"Jim Crow† laws that were mandated discriminated Blacks to have separate facilities for worship, housing, travel, schooling, lodging, eating and drinking and all other aspects of

What are the benefits to the cardiovascular system of regular exercise - Essay Example This paper is a discussion of the main physiological features of the cardiovascular system. The heart, one of the system’s major components, has two ventricles at the bottom chambers of the heart and two atria at the top chambers (Aaronson et al, 2004: p47). The ventricles force the blood into the blood vessels from the heart while the atria drains and forces blood into the ventricles. The heart is divided into two chambers in order to achieve a two-circuit system of circulation. The right side pumps to the lungs while, on the other hand, the left pumps to the other organs of the body. During the cycle of a heartbeat, the right and left atria contract, then the right and left ventricles follow suit, followed by relaxation of the ventricles and atria. During the resting phase for the ventricles and atria, blood flows from the relaxed atria to the relaxed ventricles, constituting the diastole. The atria then contract to force out any remaining blood almost followed immediately by the ventricle, constituting the systole. To ensure that blood flows in the right direction, the heart has valves that allow blood to move in only one direction. The heart valves open and close when the heart relaxes and then contracts, which is caused by the pressure difference in the heart, and these valves are; aortic, mitral, pulmonary, and tricuspid valves (Aaronson et al, 2004: p50). The one way nature of the valves ensures that blood does not flow back, which avoids mixing of different blood. The heart is comprised of the cardiac muscle, which is a striated and involuntary muscle found on its walls and histological foundations (Aaronson et al, 2004: p52). While smooth muscle is also involuntary, cardiac muscle is more anatomically related to skeletal muscle since smooth muscle is not striated. The cardiovascular system is made of an amalgamation of smooth and cardiac cells, with the blood vessels lined by smooth muscle. The circulatory system is

Issues Related to Communication in Contemporary Society Essay

Issues Related to Communication in Contemporary Society - Essay Example Culture has a great impact on communication in society for a variety of reasons. Among these is that culture provides the information that will help in understanding each other hence the eventual successful communication (Giri, 1). Culture in brief can be defined as all the activities and events that make up the life of a people who stay at certain geographical area. Through culture people are able to socialise and in this it provides the information and tools that will be in communication. Culture normally gives the norms and habits that are acceptable. In order to fit into a society one has to be able to be as everyone else. By this they have to adopt all the beliefs and norms in the society. Failure to this will lead to one being treated as an outsider and in such instances the information availed becomes limited and reduces the chances of being able to communicate. In addition without socialization, the ability to communicate may be hampered due to being unable to understand the practices of a people hence limiting the level of communication that can take place (Hauben, 2). How Culture Impacts on Communication According to Giri (1), to every culture there a certain behaviour that the males and females depending on the age will be prescribed. Hence according to the culture there will be certain institutional cultures that will be allowed along with roles in gender. Failure to observe this can lead to alienation by the society. Hence in order for an individual to properly communicate in society there is the need to act and behave within these standards in order to be accepted. Among this include the communication aspect, in this there are topics and approaches that certain genders and ages have to adopt. This will clearly impact on the level of communication as they will consider the topics and people to talk to. In addition, depending on the culture one will develop views that may be associated to either the culture or political background and this will affe ct the approach to various issues. The conversational styles learned from the culture in the society are another factor to consider as it will impact on the way one talks and acts in various situations. The culture also shapes the kind of person will become. Through to the culture and values that are practiced the personality of a person becomes shaped. In this they end having low self-esteem or the level of disclosure will also be impacted. Through this the person will limit the amount of information that they give out and receive. In doing so, the ability to communicate is hampered as no free flow of information will be able to take place. Another issue about culture is that it provides the tool that is used commonly on the day-to-day communication. By this it implies the language that is used. Each society has a culture and in this culture will be the language that is used. If one does not belong to the society, they will definitely not know the language in use and in this will b ring out the biggest challenge to communication. Hence the need to know the language in use cannot be overemphasised (Jandt, 294). Novinger (1), states that in a culture there are a certain pattern of habits and bodily behaviours that help in the interpersonal behaviours. Besides, there also the various parameters that are used in the context of interpersonal interaction. Most of the parameters

Research Method Ethnographic interview.Analysis of the interviews occurred in four stages. In the first stage, the transcripts are analyzed for concepts and themes. The comments and themes are in the transcript margins. This is the first stage. In the second stage, there was an analysis of expert files, which refers to pertinent experts which are from each interview related to each theme, and this refined the themes. These expert files, which are thematically related, were refined further. The theoretical framework of the study is linked to the thee in the fourth stage In the interviews, the interviewee explains his or her version of reality, while constructing this reality. In this way, the interviews are a kind of â€Å"interpersonal drama.† The researcher must stand back, and not direct the interview, because to insert oneself into the interview would in sert the researcher’s agenda into the issue, and the researcher might interpret the themes accordingly. There are alternate interpretations of the interview responses, and the interview should proceed in a manner which encourages this. Because respondents should answer in a way that develops his or her own perspective, the interviews should be unstructured. Nonetheless, the interviews are semi-structured, because this study has an exploratory nature. To develop the research interests of the study, open-ended questions were asked. These open-ended questions were not a strict questionnaire, however. Rather, they were simply used to tease out the key topics, and served as a reminder not to miss these topics. In the beginning of the interviews, the interviewees were given a general idea of what the focus would be. That said, the interviewees were encouraged to direct the conversation’s flow, and I would intervene only when I wanted to more about the issue. The only other t ime that I intervened was when the topic of conversation had gotten too far off of the focus of the interview. The questions were open-ended as much as possible. As the interview reached its’ close, I double-checked the question list to make sure that there was nothing important missing from the interview, and, if this was the case, I probed the interviewee further. Throughout my data collection period, I constantly added new questions to incorporate issues brought up in previous interviews. Recruitment of respondents.Ten people were recruited from the users of internet. I did not attempt to cover all ethnic groups, whichis beyond the scope of the project. Instead, I chose a particular group of people as the target of my study. To achieve the best results, they met the following two requirements: 1. They still maintain their distinctive cultural identities as ethnic people, surrounded in the sea of host countries’ mainstream culture. 2. They are not much affected by th e traditional community ethnic media, yet they are actively using the new media. That way, the influence of the computer media can be best measured. Specifically, Each participant recruited were an expert practitioner of his/her mass mediated world, knowledgeable in the most detailed and intimate ways of how it shapes their identities, which provides entry points to their complex culture condition of living on ‘borderlands’ and to their ongoing process of identity negotiation.
