Malaria Essay Example | Topics and Well Written Essays - 1500 words

Malaria - Essay Example According the research of Wolfe team, the parasite that infects chimpanzees is named as, P. reichenowi. This parasite is consisting of more genetic variability in comparison to those species which target humans. Generically, the older parasites demands more time to evolve variants; hence the diversification form of humans is far less as compared to the chimpanzees. After considering the detailed research on genomes, Stephen Rick found that the human malaria parasites are actually nested inside the parasites of chimpanzees. Meanwhile, the genetic data states P. falciparum as a mutated form of P. reichenowi. There are no such examples found either, which can relate the human malaria originated from a bird or a chicken other than chimpanzees. Stephen Rich’s theory also states that, a mosquito which feds on a chimp first and then on human, is apparently introducing the parasite into our lineage. The recent consistent observation declares that, malaria is less toxic on a chimp rath er than human. According to Stephen Rich, chimpanzees have been around longer than human hence; the host and parasite balance their relationship with each other having lots of time in hand. Greg Lanzaro states that, to solve this puzzle of origin, the malaria, human genetics, mosquito spreading malaria and the parasite should all be put together. Stephen Rich’s investigation of malaria affecting chimps and passing over to humans is still in process, through more genomes details. (Peeples, 2009) Malaria disease has been highlighted on the surface of the earth for over 4000 years ago. First, the Chinese medical writing illuminated the symptoms of malaria. These symptoms were characterized in Nei Ching, in 2700 BC. The Emperor Huang Ti was the editor of Nei Ching. The first recognition of malaria was done in Greece, during the 4th century BCE. It resulted in the decline of the population of several states

Krafts food UK - Essay Example The results indicated very strong positive correlation between flexible workplace practices and direct impact on employee performance criteria such as quantitative work output (r = +0.96), qualitative work output (r = +0.90), team working (r = +0.93) and recruitment and retention (r = +0.78). The results also indicated a very strong positive correlation between flexible workplace practices and indirect impact on employee performance criteria such as job satisfaction (r= +0.85) and organisational commitment (r = +0.87), except on stress which showed a weak positive correlation(r = +0.19). The results also indicated that majority of respondents felt that flexible work practices contributed positively towards quantity and quality of their output, increased loyalty towards the organisation and improved job satisfaction.
