The Human Brain :: essays research papers fc

The Human Brain   Ã‚  Ã‚  Ã‚  Ã‚  Through the use of molecular biology it is thought that the hominidae family first appeared about 5 million years ago. Based on this time frame it is believed that an African Hominoid lineage was present shortly before that time, approximately 10 myp, which contained the common ancestor to both the chimpanzee and human. The split into proto-chimpanzee and proto-human occurred during the last million years of the Miocene epoch. (Changeux and Chavaillon pg. 61). The fossils, especially those of the skull, from this time frame are limited. This leads to difficulty in proving differences in brain formation.   Ã‚  Ã‚  Ã‚  Ã‚  Fossils of the hominoid cranium are not available until 2 million years after the proto-human lineage begins. The lack of cranial fossils for 2 million years is a problem. We do not know what took place during this time. The first available cranial fossils are those of A. afarensis. The mean endo cranial capacity was 413.5 cm3, which means that its brain size was that of today’s African great apes (Changeux and Chavaillon pg. 65, table 4.1). With the limited fossils available and the apparent brain size of today’s African great apes there is no proof of significant differences in brain functionality.   Ã‚  Ã‚  Ã‚  Ã‚  One study done by Ralph Holloway on the endocaste of the Hadar AL 162-68 skull fragment lead to a different theory regarding significant differences in brain functionality. Hadar â€Å"concluded that the lunate sulcus would have had to be, according to the position of the interparietal sulcus, in a more posterior position than in Pan brains†. This means that A. afarensis â€Å"had an expansion of the parietal association cortex and consequently a brain reorganization (Changeux and Chavaillon pg.106)†. Brain reorganization implies that A. afarensis had a significant difference in brain functionality.   Ã‚  Ã‚  Ã‚  Ã‚  The cranial capacity of A. africanus has a mean of 440 cm3, A. robustus a mean capacity of 530 cm3 and A. boisei a mean capacity of 463.3 (Changeux and Chavaillon pg.65, table 4.1). When the limited sample size is taken into account, is there a significant difference? â€Å"The modern human inter-racial mean is of the order of 1350 cm3, which is 3.52 times that of the chimpanzee, 2.68 times that of the gorilla value, and 3.33 times the orang-utan value, the comparative inter-hominoid index values for Australopithecus species are seen to have hardly increased at all (Changeux and Chavaillon pg. 67).† If we compare the modern chimpanzee, as modern human’s closest living ancestor, to the australopithecines we find that they â€Å"show a small but definite advance over the chimpanzee in both absolute and relative brain size (Changeux and Chavaillon pg.

Qualities of Hr Manager

CASE STUDY Ans 1. -Education, job skills, experience and other competencies required for future human resource manager. * Credits in HR management. * HR and Sales experience. * To work as team leader. * Volunteer. * Result Oriented. * Good communication Skills. * Interpersonal Skills. * Competent. * Energetic. * Ability to work and deal with aggressive or strict boss. Ans 2. -All of the 4 candidates had strengths that others did not have . They all have good education, work experience but Michael Anderson has experience of 7 years and is â€Å"jack of all trades. Arthur has the best interpersonal skills and good knowledge of sales industry and can devote extra time to its position . Jane Reynolds is very competent, and is considered as the real mover and career oriented lady. Steven Robinson was the youngest among all the applicants and was full of energy and enthusiasm. Along with this, he was the only one with CHRP certificate and had good knowledge of IT and internet. Ans 3- I am partly satisfied with the selection process employed by the firm as it is a tough decision to approve any of the candidates because each have strengths that other don’t have.But making personal opinions for selection process, like Clark had a doubt about the wisdom of hiring a woman for the position or selecting Steven as he was an African-Canadian to improve company’s image of being insensitive to multicultural mosaic may result in biased selection decision. So if I would be the in charge of the selection process, I would have focussed more on the competent, career oriented behaviour of the candidates, rather than looking for all the aspects, the selection process should be more focused on the target of the firm or the expectations from the position.Ans 4-Among the candidates I believe Jane Reynolds would be most suitable for the position. As the firm management expect, the new person who is hired should be a mover and shaker, so Jane had been considered as a real â €Å"mover. † Along with this she also meets the qualification and experience requirement of the position. She don’t have a very high experience and is junior for the position but she can meet the challenges of her position, as she is a career minded lady and the position is waiting for energetic and result oriented person.

The Treaty Of Versailles - 2228 Words

Upon signing the Treaty of Versailles in June 1919, then British Prime Minister Lloyd George declared: â€Å"We will have to fight another war in 25 years time, and at three times the cost.† This ominous prediction came true as the controversial peace settlement brought no end to conflict in Europe. The Treaty was described by critics as Carthaginian: a peace so brutal it crushes the defeated side. This was the intention of the Allies, who felt a disabled Germany was the best way to preserve peace. This rationale did not satisfy Germany, who sought to undermine Versailles and succeeded in breaking the Allies’ resolve to enforce the Treaty. Ultimately, the ineffectual peace enabled Nazi ascendancy in the 1920s and 30s. Discontentment with the Weimar government, responsible for signing the Treaty, provided a receptive audience for Hitler s hard-line policies, which were designed specifically to regain German supremacy. The signatories to the Treaty allowed Germany to viol ate successive terms without reprisal, which led inevitably and inexorably to the Second World War. Thus, the real criticism of the Treaty lies in its lack of enforcement. The Treaty’s brutality has been a source of unceasing critical contention. Whilst commentators during the interwar period slammed the Treaty for its vindictive and punishing terms, modern historians claim they could have been far harsher.

Pros and Cons for Paying Organ Donors - 1534 Words

My grandfather was a lucky one, though he had to wait 5 years until his luck was fully granted. He was diagnosed with sever kidney failure, spent 5 years on dialysis, then was blessed with the option of getting a kidney†¦ twice. Though the first time he had to reject because of the health of his wife-after her death, he was called once more with the option of having a kidney transplant. However, my grandfather is an exception, most people do not get called once, let alone twice, for the option of receiving a kidney. As of October 25th 2013, about 100,000 people were waiting for a new kidney in the United States. (SCU) Every day, 18 people from that list die along with 10 others being added. As of October 25th, 2013, out of the 100,000 people waiting for a new kidney while only about 10,000 received one; that means 90,000 people are either rolled over to the next year, or die waiting. The marvelousness of kidney donations, compared to other organs donations, is that each per son is born with two and can sustain a healthy life with just one; simple facts such as this is what has driven the black market kidney trade to flourish. (CBSNEWS) However, if this is the case then why aren’t more people donating? Is it because they are not getting something in return? Why donate for free when someone on the black market will pay 10,000 dollars?

Boko Haram Africa Of Peril - 1529 Words

Boko Haram: Africa in Peril The African Continent has had numerous problems in the last century that have caused low development, low hygiene, and high death rates. These problems include finances, lack of clean food and water, poor weather, diseases, and terrorist attacks. All of these problems can cause death, poverty, or a need to emigrate from the area. For years these problems have made it difficult to develop these countries to enable them to help their citizens and vanquish these problems. Terrorism is a large threat to Africa, but mainly in Western Africa, due to the large group known as Boko Haram. Boko Haram has done mass abductions, displaced millions from their homes, and killed thousands. To understand how Boko Haram effects Africa one must be familiar with their history and attacks,tactics and strategy, and their organization and recruitment. Boko Haram has a brief, but very eventful history where it has gone through periods of violence, allegiance to other groups, and turmoil within their group. The group was founded in 2002 by Mohammed Yusuf in Maiduguri, the northern state Borno. A religious center was set up here, where it attracted Muslims to create an Islamic State. For example, in an article by Africa Check Boko Haram’s founding was discussed: â€Å"The group now known as Boko Haram began to emerge in 2002, when a collection of like-minded Islamists retreated to a remote area of the northeast called Kanamma†¦ They had been followers of a young, charismatic
