The main objective of this study was to investigate the perception of the researchers and officers within the National Institutes of Health Malaysia (NIH) about their understanding of knowledge sharing practices in their respective environment. Questions included: what are the perceptions of the respondents with regard to the knowledge sharing practices in their respective institutions? What are the benefits for knowledge sharing practices as perceived by them? What are their perceived organisational knowledge sharing practices motivating factors? Also, what are the hindering factors? The survey of the researchers and officers of the NIH was distributed to 400 respondents from the six research institutes under NIH: Institute for Medical Research (IMR), Institute for Public Health (IPH), Network for Clinical Research Centres (CRC), Institute for Health Management (IHM), Institute for Health Systems Research (IHSR) and Institute for Health Promotion (IHP). The responses indicated that knowledge sharing depends on the context of encouraging and rewarding the practices of organisational knowledge sharing. The findings suggest four factors – Environment and Infrastructure, Management Support, Culture and Technology – as significant determinants in influencing the organisational knowledge sharing practices among the employees. The study was limited to the perceptual aspect of the issue, specifically from the individuals’ opinions and sentiments. 相似文献

This study explored the problems undergraduate students are faced with in citing references in their academic work. The study revealed that undergraduate students face difficulties in citing references in their academic work and that they are inconsistent in the way they cite. The article suggests ways in which faculty and library staff can work together to address this problem. 相似文献

Endothelial cell death due to increased reactive oxygen species(ROS) may contribute to the initial endothelial injury,which promotes atherosclerotic lesion formation.Piper sarmentosum(PS),a natural product,has been shown to have an antioxidant property,which is hypothesized to inhibit production of ROS and prevent cell injury.Thus,the present study was designed to determine the effects of PS on the hydrogen peroxide(H2O2)-induced oxidative cell damage in cultured human umbilical vein endothelial cells(HUVECs).In this experiment,HUVECs were obtained by collagenase perfusion of the large vein in the umbilical cord and cultured in medium M200 supplemented with low serum growth supplementation(LSGS).HUVECs were treated with various concentrations of H2O2(0-1000 μmol/L) and it was observed that 180 μmol/L H2O2 reduced cell viability by 50% as denoted by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) assay.Using the above concentration as the positive control,the H2O2-induced HUVECs were concomitantly treated with various concentrations(100,150,250 and 300 μg/ml) of three different extracts(aqueous,methanol and hexane) of PS.Malondialdehyde(MDA),superoxide dismutase(SOD),catalase(CAT) and glutathione peroxidase(GPX) levels showed a significant increase(P0.05) in HUVECs compared to the negative control.However,PS extracts showed a protective effect on HUVECs from H2O2-induced cell apoptosis with a significant reduction in MDA,SOD,CAT and GPX levels(P0.05).Furthermore,PS had exhibited ferric reducing antioxidant power with its high phenolic content.Hence,it was concluded that PS plays a beneficial role in reducing oxidative stress in H2O2-induced HUVECs. 相似文献

Islamic Ramadan is a 29-30 day fast in which food, fluids, medications, drugs and smoking are prohibited during the daylight hours which can be extended between 13 and 18 h · day(-1) depending on the geographical location and season. The majority of health-specific findings related to Ramadan fasting are mixed. The likely causes for these heterogeneous findings lie in the amount of daily time of fasting, number of subjects who smoke, take oral medications, and/or receive intravenous fluids, in the type of food and eating habits and in changes in lifestyle. During Ramadan fasting, glucose homeostasis is maintained by meals taken during night time before dawn and by liver glycogen stores. Changes in serum lipids are variable and depend on the quality and quantity of food intake, physical activity and exercise, and changes in body weight. Compliant, well-controlled type II diabetics may observe Ramadan fasting, but fasting is not recommended for type I, noncompliant, poorly controlled and pregnant diabetics. There are no adverse effects of Ramadan fasting on respiratory and cardiovascular systems, haematologic profile, endocrine, and neuropsychiatric functions. Conclusions: Although Ramadan fasting is safe for all healthy individuals, those with various diseases should consult their physicians and follow medical and scientific recommendations. 相似文献

An experiment was carried out to examine the effects of light quality on the growth and development of antirrhinum under three different temperatures 19℃, 24℃ and 27℃ in glasshouses. Five different colour filters (i.e. 'Red absorbing', 'Blue absorbing', 'Blue and Red absorbing' and two 'partially Blue absorbing' materials) were 相似文献

One of the most fascinating aspects in the life of birds is their breeding phase, which is intimately tied to the distribution
and abundance of food resources in their environment. However, food is not evenly distributed in space and time, and this
is thought to have been one of the factors affecting the evolution nesting strategies. To understand how birds have evolved
different types of nesting patterns ornithologists have used a variety of approaches, the most useful of which have been to
build simple models based on optimality principles. 相似文献
