Summary - Essay Example Rituals are well established form of cultural practices or ceremonies that mark a certain social rite in the society. Although modernity or globalization has contributed to some changes in the African societies, many African societies are still attached to cultural practices, traditions and customary issues. Cultural, traditional and ritual practices are widespread in African societies. The Ndebele people are well known for being artistic people because of artistic creativity and decorations of their homestead. Their historical perspective focuses on the ritualistic practices especially male and female initiation and marriage as well as religious practices or beliefs (Sian Tiley-Nel par.1). The Ndebele people are famous because of creativity in art, traditional practices and religious beliefs. They practice male and female initiation ceremonies known as ingoma or wela and iqhude or ukuthombisa respectively. Marriage ceremony is significant to them, and their ancestors, influences their daily practices. The African coming-of –age rituals are viewed as consisting of three main stages, which includes separation from the society, transcription period and reincorporation into community (Hipple par.3). The first phase involves taking boys and girls into the forest, which is notable for ritual activities. The second phase of transition involves initiating learning activities and training boys and girls on significant skills that will help them to participate in the society. For instance, the Krobo of Ghana trains girls for three weeks on various issues such as ways of dancing and art of seduction, female behaviors in the society and the domestic core skills. However, the initial process for girls in the Senufo of Ivory Coast takes a period of seven or eight years. The third phase reincorporation into society, which is the last phase for African coming of age rituals. This stage involves varied ordeals and tests that are usually painful. The

Multitasking - Essay Example Computer multitasking within the single core microprocessor entails time sharing of the processor. This is because only one activity can be performed at one time; however, the tasks are rotated many times per second. In multi-core computers, the core can engage in separate task at the same time. The first publication of the term â€Å"multitasking† initially appeared in the IBM paper that illustrated the effectiveness of the 1965 IBM System/360. As from the 1960s, many psychologists have done studies and experiments on the aspect of human multitasking. The basic experimental design applied in the analysis of human multitasking involves the psychological refractory period effect. In the experimental design, individuals are required to perform separate responses for the two stimuli that are presented within close time duration. The most general research result illustrates reduction in the response levels during the second stimulus. Researchers increasingly suggest existence of processing bottlenecks, which hinder the brain from handing certain key aspects of the several tasks simultaneously. The researchers further illustrates that the cognitive process that experience severe bottlenecks is the memory planning and information retrieval (Steven, Adam & Arturo 1321). Psychiatrist Edward Hallowell has explained multitasking as people mythically believing that they can engage in several tasks, effectively as one. On the contrary, there is adequate evidence that individuals have the capability of performing motor and perceptual activities at similar time. Several researchers have also analyzed multitasking in the process of learning. Some researchers analyzed the concept of cognitive loading during multimedia learning. The two illustrated that it is challenging or even impossible to acquire new information when multitasking. Multitasking negatively influence academic performance. This shows that learners who participate in high multitasking levels
