Are modern humans biologically related to Neanderthals Essay

Are modern humans biologically related to Neanderthals - Essay Example The result of the studies shows that the modern humans originated from Africa about 150,000 years ago and were dispersed to other parts of the world where they replaced Neanderthals rather than interbreeding with them. This is clearly evidenced by the discovery of skeletal remains of anatomically modern humans in different parts of the world. Anatomically modern humans were discovered in Africa while distinctively modern humans were discovered in Europe and Asia. The anatomically modern humans existed 150,000 years ago while the distinctive modern populations existed 40,000 years ago. Archaeological evidence also shows that Aurignacian technologies were spread across central, southeastern and Western Europe through the dispersion modern human from Africa. The Aurignacian technologies of modern human emerged directly from the Neanderthal technologies; indicating that the Neanderthals of Asia and Europe associated with new populations from Africa. Another group of the modern human was dispersed along the coastal Mediterranean of Europe. Neanderthal genes disappeared in Europe because there was a direct competition between the Neanderthals and the modern humans in terms space and resources. The modern humans won because they had more complex technology and organization.According to Mellars (2004), there must have been great contact and interaction between modern populations expanding into Europe and the indigenous Neanderthals across Europe. These interactions were mainly behavioral.

The 'colored revolutions' of Eastern Europe and their success factors Essay

The 'colored revolutions' of Eastern Europe and their success factors - Essay Example The egalitarian revolutions of 1989 in Central and Eastern Europe have been labeled as the conclusion of the "third wave" of worldwide democratization that instigated in Spain and Portugal in the mid-1970s. It is certainly alluring to see the breakdown of the Soviet territory as segment of a universal disintegration of autocracies. This opinion surely prejudiced how the democratic changeover in Eastern and Central Europe has been observed in the West (as the "end of history") as well as by some of its characters. Ten years after, nonetheless, even with widespread Western exertions at democracy advancement, the democratic current has rather withdrawn, leaving a depiction of accomplishments in Central Europe (along with in Latin America and fragments of Asia) counterbalance by hindrances in the earlier Soviet Union and the Balkans (but similarly in China and most of Africa) (Jacques, 2000). Body The examination of the consequences of domestic changes for the local system of international dealings should take place from the implication of the main factors and procedures, which formed the post-soviet space design in the last decade. The first amongst these is the procedure of state and nation-structuring in the Afresh Independent States. Fresh political leaders in the previous Soviet states had a particular image of their state-projects which, as a law, protected Euro-Atlantic ambitions and, in reality, detached relations with Russia as well collaboration in the post-Soviet region from the list of primacies in their foreign policy schedules. Secondly, these objectives, along with the fluctuations in Europe and its boundary, stemmed in the participation of outside troupes in the post-soviet district - US, EU, NATO, and the Western European countries, and, some local actors, i.e. Poland, Turkey, China, , etc. The third actor in the post-Soviet district was Russia, which was sign ificantly annoyed by the appearance by the above-mentioned influences in its Immediate Abroad, as Moscow had its own fairly dissimilar vision for the expansion of this region (Samokhvalov, 2005). Examination of the second upsurge of democratic evolution in Eastern and Central Europe’s â€Å"color revolutions† has inclined to emphasize on fundamental variables such as district dispersion, leadership policy, and popular demonstration. However it may be imprecise to label the post-communist dictatorial throughputs the area has seen as part of a â€Å"surge†; elongated-term variables such as state and event capability and the power of a country’s association to the West may apprehended shed light on why certain nations have observed such revolutions whereas others have not (Way, 2008). The discussion on the color revolutions is mainly about the comparative significance credited to dispersion versus certain main operational factors. Amongst these features is t he amount and influence of Western force, which fluctuates subject to the degree of connection to Western Europe as well as the United States. In the stumpy-association previous Soviet states, domestic powers—particularly, the strong suit of the mandatory state and political party—

Good Country People Essay Example | Topics and Well Written Essays - 750 words

Good Country People - Essay Example The story â€Å"Good country people† portrays a number of aspects that are crucial to the development of the plot in the story, as well as bringing out the meaning. The aspects include perspective, conflict and the tone used in the story, which this paper seeks to bring out in an analysis of the story The story brings out a feminist perspective owing to the characters used in the book (O’Connor 1). This is following the Hopewell family composition and the family of Mrs. Freeman, where in the two families, there do not exist male elements, as either sons or parents.. As a result, the story follows the lives of the women found in these families, with the main character being Joy, the daughter of Mrs. Hopewell. Feminist is also portrayed by the presence of the strong educational background that Joy, also known as Hulga, has. This is by having a college education all through to Doctoral degree, which shows the power that a woman holds provides she has an education. This is due to her tendency to dissociate with other members of the society due to her pride. In addition, the story also brings out the conflict between science and religion. This is in relation to Joy’s atheist and nihilistic point of view towards the world and people, where she practices her atheist beliefs on a young Bible salesperson (Bosco 284). This is as portrayed by her intentions on the second that the couple goes on after Manley asks Joy out. There is also the case where Manley steals Joy’s prosthetic limb due to his fetish for artificial body pars belonging to women. This is unbecoming behavior of a person expected to be of upright moral standing. As a result, this serves a means to broaden the conflict between religion and science, as well as social issues. She denies the existence of God, but she still works towards finding some form of spiritual enlightenment by going out with Manley. In addition, the conflict of morality and ethics is also brought up in the sto ry. This is following the deception of Manley in order to get to Joy, by pretending to be a bible salesperson and deceiving Mrs. Hopewell that he is poor and getting her to take pity on him. This shows how far moral degradation has gone to the point where religion can be used for personal gain. The above is portrayed by Manley when he opens his case to reveal two fake bibles, a flask of whiskey and a park of cards among other things. Moreover, the whole story is written from a third person’s point of view, who in this case is a narrator. For this reason, the story is based on observation and not on the experience of the narrator meaning that, the story may bear a bias due to the nature of the narrator. The narrator tells of the events that take place in the lives of the women in the two families, moreover, their lives are portrayed as monotonous. As a result, it focuses on the nature of life for women in a society where tradition is embraced as a social norm, and those that a re go against it are labeled as ingrates who are ungrateful for the same values that helped raise them. This is as the case of Joy or Hulga who views her mother as a backward person, as she lives as per traditional conventions as shown by her dressing. The tone used is that of disgust or anger directed towards the nature of the earth at the time of writing the story. This is owing to the prevalence of lack of honesty among country people, which is brought out by the fact that Manley is a swindler in Mrs. Hopewell’s house (O’Connor 15). Disgust is also shown following the open disadvantage at which Joy is following the relations that she has with Manley. At the point that Manley takes Joy’s foot, the tone is brought out clearly following the state that Joy is left, vulnerable. This shows anger at the world for its unfair practices especially where they are least expected, from a religious person, Manley. In addition, it shows anger at the discriminative practices directed at people with disability due to Joy’

Vietnam War and American Pop Music Term Paper Example | Topics and Well Written Essays - 1250 words

Vietnam War and American Pop Music - Term Paper Example Feminism, African-American Civil Rights Movement, Anti-Vietnam War Protests and even Sexual Revolution occurred in the Sixties. But there is no revolution in that era that has had the profound effect like the one the Vietnam War had. The Vietnam War has left a huge mark in America’s social psyche, and subsequently made an impact in the collective consciousness of the American people. Many films have been made, songs, books and even TV shows that echoed the sentiments of the people during that time. This era changed the people’s view on media, politics, the government and other institutions. If the people in the other eras before trusted the government with its actions, this era saw that the people did not trust the government as much because it deployed their sons to another country, in what the Americans viewed as a futile war. The Vietnam War actually started in 1955. As an offshoot of the Cold War between the Communist Russia and the Democratic United States, the Vie tnam war is also about the battle of communism and democracy. It was between the communist Vietnam (North), controlled by the Viet Congs and the democratic Vietnam (South). The US, as a protector of liberty, tried to protect the democratic Vietnam from the communists who were trying to unite Vietnam by making the country a wholly communist one. Because of this threat to democracy, America rounded up its troops, mostly composed of young men. In 1960, the first massive recruits occurred, doubling up in numbers in 1962, and in 1963, the world saw that the American troops have tripled in number. These young troops were to be deployed in Vietnam. This happening, along with other socio-cultural movements in the 60s, spurred a massive protest movement. It has to be noted that this era saw the African-Americans being granted equal rights, the women equality with men, the environment being taken importance, etc. This war added to the agenda that the people were so keen to push. The people di d not want to wage war, unlike the government. The people pushed for peace and focusing on the environment, not having their sons, brothers and husbands killed. This conflict between the people and the government spurred the people’s disillusionment on the American government. This event, the Vietnam War, challenged their views pertaining to their leaders and their heads of state. It was inevitable anyway, the troops were sent to fight in the war. For nineteen years the United States has been deploying troops over at the Asian country. They lost the war. This fueled the masses’ discontent for the government. This discontent permeated through the pop culture. It has made its way in the people’s everyday lives, especially with the movies and music. Art is a reflection of reality. Music and movies are art forms and they do reflect reality in whatever form they can, intentionally or not, since the creators’ consciousness also reflects the events that happen a round him, through the art he has been making. This is especially true in protest music that made its way into the lives of the Americans in the 60s. Protest music is a result of a musician’s conscious effort to be heard. The rise of protest music in the United States was seen during the time of the Vietnam War. True, protest music existed way before, ever since man started to sing, but the Vietnam War, with the

Critically assess the view that using drugs leads to crime Essay

Critically assess the view that using drugs leads to crime - Essay Example These situations illustrate an obvious association between drugs and crime. However, it is difficult to accurately determine to what extent in which drugs could be considered the main motivation for crimes. A person under the influence of an illegal drug while committing a crime does not necessarily mean that the crime was drug-related. To what extent the drug clouded their judgment is subjective at best. That person may be a cigarette smoker as well but the crime would certainly not be classified as tobacco-related. Theories such as Strain, Labeling and Socialisation explain causations for crime and can also be applied to drug usage, but all drug users do not commit crimes and all criminals do not use drugs. The connections between drug use and crime are complex and explanations vary widely. This has been a topic that has garnered a considerable amount of attention for the past few decades among the public, media and politicians because of the considerable negative social and econom ic impact on society as a whole and the victims of crime. Some argue that laws make criminals out of drug users and distributors. Prohibition acts to encourage organized criminal activity because of the high profitability involved. In addition, the inflated expense of drugs is the main reason a user has to resort to crime to support their habit. Broadly differing arguments are offered regarding the degree to which criminal activity is driven by drug use. The term ‘drug user’ cannot be used without qualification when connecting this activity to crimes of any description. Drugs such as amphetamines, cocaine, phencyclidine, (PCP), barbiturates and alcohol are more closely connected to criminal acts of violence than are heroin and marijuana according to current scientific literature (Wright & Klee, 2001). Some statistics that show a linkage from drug use to crime are generated from drug tests on prisoners. If the

Evidence-Based Practice Paper and Intervention Presentation on Essay

Evidence-Based Practice Paper and Intervention Presentation on Diabetes (Benchmark Assessment) - Essay Example Primarily, DM diagnosis relies on the measurement of plasma glucose levels. This diagnostic mode is effective in detecting diabetics and pre-diabetics, but it does not offer a clear mode of assessing resultant complications, which often start in the vascular system. The diagnosis therefore, only tests tolerance to glucose, and not the associated risks such as the vascular risks (Pavri, 2001). The further assessment of risk may be necessary in monitoring the condition and administration of treatment, but it has not been available. However, a recent research by Zampetaki and others has led to the discovery of biomarkers that can be used in diagnosing and monitoring type II diabetes and its associated risk (Zampetaki et al., 2010). Description of Diagnostic Tool The new diagnostic tool uses microarray screening and real-time polymerase chain reaction (PCR) processes to monitor MicroRNAs (miRNAs), which have been positively associated with the development of the condition and its progres sion. This new tool offers significant prognostic ability to predict and monitor type II DM. The miRNAs are small group of RNAs not involved in coding. They instead work as repressors in translation (Zampetaki et al., 2010). The miRNAs bind to complementing sites by base pairing on untranslated portions of the target mRNA. They are responsible for directing repression or degradation of the transcripts. Research has shown that miRNAs influence stress responses, oncogenesis, development and angiogenesis. They also play a significant role in endothelial cell functioning as well as the regulation of angiogenic potential and inflammations. The study found that miRNAs change prior to the start of type II DM (Zampetaki et al., 2010). The changes were narrowed to miRNA-126, which was found to profoundly change with type II DM (Larkin, 2010). This provided proof for a plasma Micro-RNA signature for patients with type II DM, thus suggesting a possible prognostic value in monitoring and diagno sing DM (Zampetaki et al., 2010). Summary of Research The study on miRNAs and DM was part of a wider Italy-based Bruneck Research on various conditions including cardiovascular diseases. The study was initiated in 1990 by â€Å"King’s College London British Heart Foundation Centre (Larkin, 2010).† The researchers sampled and measured miRNAs from a total of 822 participants. Some of the participants had type II DM, whereas; others were controls. The measurements were conducted in five phases on an annual basis from 1990 to 2005. The use of microarray screening and real-time PCR identified 700 miRNAs. The researchers then used miRNA relevance network inference technique to understand the miRNAs regulatory networks. The technique revealed changes in the levels of some five miRNAs prior to the start of type II DM. Notably, miRNA-126 was found to show a consistent decline, which was correlated to the incidence and prevalence of type II DM (Zampetaki et al., 2010). The fact that miRNA-126 is significant in wound repair and vessel health implies that its decline is an indicator of vascular risk levels associated with DM. miRNA-126 is rich in normally functioning endothelial cells and its decline associated with DM may be an indicator of the progression of deterioration caused by DM, which increases vascular risk (Zampetaki et al., 2010). As such, miRNA can be a significant prognostic tool in monitoring DM and associated risks (Larkin, 2010). The study

Reflections and Reminiscences of an Early Years Educator Essay

Reflections and Reminiscences of an Early Years Educator - Essay Example ucation research paradigm challenged and supported me to investigate knowledge and realities about early years’ teaching in the UK in interviewing a retired teacher. Inevitably, this kind of research is iterative in nature with inextricable linkage between practice and research and evolving continuously. Therefore, through an exploration of the retired early years’ teacher practice, her social locations, subject positions, personal experiences, and interpretations will be examined via her voice (Cahnmann-Taylor & Siegesmund, 2013: p29). Using a range of appropriate literature, I will justify the need for a personal reflective narrative inquiry of a former teacher in the UK Pre-school education sector, which should elicit information about how she reminisces on her work as an early years’ teacher. It is expected that I will elicit information on the interactions that she had with pre-school children aged between three and four years as she nurtured and cared for them prior to retiring from her position some time back. I will specifically identify how I engaged in the narrative inquiry, identifying details on the participants, ethical considerations encountered during the study, my reflexivity process, the data collection process, and its analysis. Moreover, I will also present a discussion of the findings. Arts based education research is a method of research that aims to use arts-based concepts, practice, and techniques in understanding education. Normally, practitioners utilize various arts-based methodologies in conducting their research, as well as communicating their findings, through genres as diverse as visual arts, poetry, performance, music, dance, and narrative (Loh, 2013: p8). I used the latter genre in conducting my arts-based education research. Narrative arts-based education research, which I will refer to as NABER from this point, is based firmly on the premise that we understand and attach meaning to our experiences through stories. As a type
