Examining antecedents of knowledge-sharing factors on research supervision: An empirical study

The use of an effective supervision mechanism is crucial between a student and supervisor. The essential knowledge shared and transferred between these two parties must be observed and understood very well in order to ensure that students are produced at good level of quality for future professional knowledge workers. The aim of this study was to conduct an assessment of the impact of individual, organisational and technical factors on knowledge sharing in a research supervision domain. In order to achieve this aim, a specific research model was developed. This model was based on systematically analysing and extracting all the knowledge-sharing impact factors and then choosing the more iterative and adaptable ones, according to research supervision models. These factors categorized to individual, organizational and technological factors. To effectively evaluate the research model, a quantitative research method was adopted. Data was collected by a survey of 150 students from the Faculty of Computing at Universiti Teknologi Malaysia. The Smart PLS tool was used for data analysis. In sum, the results of this research show that the individual factor in the research supervision domain – namely, the ability of students to share knowledge – in addition to technological factors – specifically, IT systems – have the greatest impact on knowledge sharing in the supervision process. In addition, it was shown that organisational factors including the culture of the university, social networks, and supervisor support have a positive impact on knowledge sharing in research supervision. However, when compared with individual and technical factors, the effect of organisational factors on knowledge sharing in research supervision was not particularly strong in the case of this study. A positive relationship did not exist between the learning strategy and knowledge sharing in research supervision. This study is among the first of its kind to empirically examine the antecedent factors of knowledge sharing in the context of research supervision.     

Visual constraints in written word recognition: evidence from the optimal viewing‐position effect

In this paper we review the literature on visual constraints in written word processing. We notice that not all letters are equally visible to the reader. The letter that is most visible is the letter that is fixated. The visibility of the other letters depends on the distance between the letters and the fixation location, whether the letters are outer or inner letters of the word, and whether the letters lie to the left or to the right of the fixation location. Because of these three factors, word recognition depends on the viewing position. In languages read from left to right, the optimal viewing position is situated between the beginning and the middle of the word. This optimal viewing position is the result of an interplay of four variables: the distance between the viewing position and the farthest letter, the fact that the word beginning is usually more informative than the word end, the fact that during reading words have been recognised a lot of times after fixation on this letter position and the fact that stimuli in the right visual field have direct access to the left cerebral hemisphere. For languages read from right to left, the first three variables pull the optimal viewing position towards the right side of the word (which is the word beginning), but the fourth variable counteracts these forces to some extent. Therefore, the asymmetry of the optimum viewing‐position curve is less clear in Hebrew and Arabic than in French and Dutch.     

Discourses of Exclusion and Inclusion in the South: Limits and Possibilities

The primary purpose of the article is to lookat how current thinking in the social sciences conceptualizes discourses of inclusion and exclusion in education and what the value of this thinking is for policy development incountries like South Africa and India. The article argues that the main conceptual weakness of current understandings is a failureto adequately engage with social justice concerns. While current approaches promote the achievement of certain kinds of rights, they are often complicit in the denial of others.This is because, the article seeks to show, the policy text in many countries, including countries of the South, invariably defines individuals and groups in essentialized terms and fails to engage with the complexity of their identities.     

Polymorphonuclear leukocyte mediated oxidative inactivation of alpha-1-proteinase inhibitor: Modulation by nitric oxide

Alpha-1-proteinase inhibitor activity was studied in presence of resting and activated polymorphonuclear leucocytes. Four different agonists; phorbol myristic acetate, N-formyl-methionyl-leucyl-phenylalanine, opsonised zymosan and arachidonic acid decreased the inhibitor activity by 23.3%, 20%, 12% and 16.6^ respectively. The inhibitor activity was protected by using various free radical scavengers. Catalase and superoxide dismutase both restored activity by about 18%, mannitol by 13% and sodium azide by 17.3%. The inhibitor activity was also protected significantly by pretreatment of polymorphs with L-Arg, a precursor of nitric oxide, before activation. L-Arg was also observed to suppress the generation of superoxide and hydroxyl radical appreciably. The nitric oxide synthase inhibitor, aminoguanidine drastically inhibited the nitrite release and reversed the protection offered by L-Arg to the inhibitor activity. Our results indicate a multifactorial nature of the inactivation process, the culprit species being superoxide, hydrogen peroxide, hydroxyl radical and hypohalides. Nitric oxide seems to scavenge the superoxide radical directly after its formation rather than inhibiting its generation by NADPH oxidase as was believed earlier.     

Researching 'my people,' researching myself: Fragments of a reflexive tale

The paper investigates my positionality as a Pakistani Muslim researcher, affiliated with a U.S. institution, conducting ethnographic research with Pakistani Muslim immigrants in California. Three vignettes reconstructed from field-notes and a reflective journal illustrate the tensions and contradictions informing the research process. The first vignette details my shifting subjectivities in relation to a segment of the Muslim community in Northern California. Although my perceived disempowerment of Muslims motivated my research, my failure to subscribe to the Muslim Student Association's version of Islam cost me their disapproval. The second vignette highlights my relationship with one particular research participant. Although I shared the same ethnic background as this participant, my inability to conceive of her empowerment in terms other than those of Western feminism led to tragedy. The last vignette focuses on my interaction with the ethnographic data at my desk and becomes an analysis of the forces in my life that feed into my research.
