Recent evidence shows that dynamic instability is the dominant mechanism for the assembly of pure tubulin in vitro and for the great majority of microtubules in the mitotic spindle and the interphase cytoplasmic microtubule complex. The basic concepts of this model provide a framework for future characterization of the molecular basis of spatial and temporal regulation of microtubule dynamics in the cell and the function of microtubule dynamics in motile processes such as chromosome movement.

This work is of the view that the question of being is not only a problem in Western philosophy but also in African philosophy. It, therefore, posits that being is that which is and has both abstract and concrete aspect. The work arrives at this conclusion by critically analyzing and evaluating the views of some key African philosophers with respect to being. With this, it discovers that the way that these African philosophers have postulated the idea of being is in (...) the same manner like their Western philosophers whom they tried to criticize. This work tries to synthesize the notions of beings of these African philosophers in order to reach at a better understanding of being. This notion of being leans heavily on Asouzu’s ibuanyidanda ontology which does not bifurcate or polarize being, but harmonizes entities or realities that seem to be contrary or opposing in being.

The overall objective of this research is to determine the religious perceptions and its levels of university youth and to interpret the findings from the point of view of their psychological features. This research consists of four chapter. These are: introduction, first chapter consist of discussions of the basic concepts such as religiosity, spirituality, second chapter that the data obtained from the survey was assessed the relationships with hypotheses and conclusions in which the findings were interpreted. The study’s population consists (...) of the students at the undergraduate level in faculties of the Erciyes University in 2011-2012. A questionnaire was administered on 553 students, chosen randomly in this population. The survey contains descriptive and Likert style items. As independent variables in this study, branches of science, faculty, department, class, age, gender, living environment for the longest time before coming to university, graduated high school, mother's and father's education level and the accommodation place during training have been taken. When analyzing the data, percentages, frequency distributions, descriptive statistics, analysis of variance (one-way ANOVA) and T-Tests and Chi-Square (x²) techniques were used. As a result of this research hypotheses associated with gender, age, branches of science, faculty and department were confirmed on the other hand the others were rejected. (shrink)

This is a general account of the Cappadocian Christian Father Gregory of Nyssa (c. 335 - c. 395 CE) as a philosopher. The article is divided into a discussion of his life and his views on God, the world, humanity, history, knowledge, and virtue. A common thread, which would later be systematized in the Palamite essence-energies distinction, is traced in all these topics. Of particular interest to philosophers are comparisons with John Locke and Immanuel Kant.

The studies of urban popular culture in modern China in recent years have attracted wide attention from scholars in China and abroad. The symposium, which is composed by Ma Min’s “Injecting vitality into the studies of urban cultural history,” Jiang Jin’s “Issues in the studies of urban popular culture in modern China,” Wang Di’s “The microcosm of Chinese cities: The perspective and methodology of studying urban popular culture from the case of teahouses in Chengdu,” Joseph W. Esherick’s “Remaking the Chinese (...) city: Urban space and urban culture” and Lu Hanchao’s “From elites to common people: The downward trend in the studies of Chinese urban history in the United States,” provide valuable insights on the perspective, trend, and methodology of the studies.

Although the topic of value congruence has attracted considerable attention from researchers and practitioners, evidence for the link between person–supervisor value congruence and followers’ reactions is less robust than often assumed. This study addresses three central issues in our understanding of person–supervisor value congruence by assessing the impact of objective person–supervisor value congruence rather than subjective value congruence, by examining the differential effects of value congruence in strongly versus moderately held values, and by exploring perceived empowerment as a central mediating (...) mechanism. Results of a multi-source study comprising 116 person–supervisor dyads reveal that objective value congruence relates to followers’ job satisfaction and affective commitment and that this link can be explained by followers’ perceived empowerment. Moreover, polynomial regression and response surface analyses reveal that congruence effects vary with the importance that leaders and followers ascribe to a certain value: Congruency in strongly held values have more robust relations with followers’ outcomes than congruence in moderately held values.

Understanding a proposition for an intelligent agent is an important epistemic concept. We first discuss intuitively general logic characteristics of understanding, and give a language and a semantics containing understanding as a modal operator. Secondly, we develop the system LU for the operator, give some results of its proof theory, and then we prove the frame soundness and frame completeness of LU.
