This study determines the preferable leadership practised by colleges’ directors, institutional factors and challenges encountered in knowledge sharing in Malaysian technical higher learning institutions (HLIs). Using a pragmatic mixed-method strand, we obtained 212 teachers and instructors’ viewpoints on knowledge sharing factors and barriers. The study also interviewed four teachers in exploring college directors’ leadership practices and issues faced while sharing their knowledge and experiences with their colleagues. The findings revealed that technical college teachers favoured enabling others to act as a preferable leadership practice that empirically supports their knowledge sharing practices. Thus, reward system and culture were antecedents and significant predictors for teachers’ knowledge sharing practices in technical HLIs compared with their colleges directors’ transformational leadership practices. Teachers also highlighted that their directors provide affirmative responses concerning the knowledge sharing activities; thus, practising their roles as a knowledge sharing catalysts. However, lack of support from the management, micro-politics and teachers’ own negative perceptions were identified as challenges and constraints teachers encountered while sharing their knowledge with their peers. The findings put forward some suggestions for improvement on technical college’s knowledge sharing practices. 相似文献

Scandix pecten-veneris L. is a less studied wild edible herb and is considered an extinct plant species in many parts of the world. This study was designed to evaluate its phytochemical composition and biological potential of S. pecten-veneris L.
Methods
Phytochemicals including alkaloids, flavonoids, polyphenols, and tannins were determined in extracts of S. pecten-veneris. Antioxidant activity was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH), while reducing power was tested by ferric reducing/antioxidant power (FRAP) assay. Antimicrobial activity against seven bacterial and four fungal strains was evaluated using agar well diffusion assay. Enzymes inhibition study was performed for urease, phosphodiesterase-I, and catalase-II.
Results
S. pecten-veneris showed moderate antiradical activity and reducing potential of hydroxyl radicals to about 20% of the initial value. The antioxidant activity of various extracts of S. pecten-veneris showed a linear correlation with total phenolic contents in the order of water>n-butanol>chloroform>ethyl acetate>methanol extracts. S. pecten-veneris leaves showed the highest inhibitory activity against Staphylococcus aureus while the highest antifungal activity was observed against Candida albicans. The plant extract was most potent against urease enzymes but showed moderate activity against phosphodiestrase-I and carbonic anhydrase-II.
Conclusions
Our data demonstrate that in addition to its culinary uses, S. pecten-veneris has good medicinal potential and hence could be used for treating some specific health ailments.
This investigation evaluated whether the mirror image could be confirmed and extended to include an ally and an enemy's ally. At the time of the 1973 Arab-Israeli War, 50 Arab students (chiefly from the confrontation states) who were attending Pakistani universities completed five semantic differental scales (brave-coward, honest-deceitful, kind-cruel, peaceful-agressive and dependable-unreliable) on two matricss: (1) Self-image and Enemy-image, (2) Ally-image and Enemy's Ally-image. Fifty Israeli students at Hebrew University also completed the scales. Thus, both groups rated Americans, Arabs, Israelis and Russians for the appropriate categories. Results confirm the mirror image from both Arabs and Israelis and its extension to Ally-image and Enemy's Ally-image. The data are somewhat clearer for the Arabs. Ratings for Israelis' Ally (Americans) are about as high as Self. The discussion offers possible explanations of the results.相似文献

This study examined the associations between pre-game wellness and changes in match running performance normalised to either (i) playing time, (ii) post-match RPE or (iii) both playing time and post-match RPE, over the course of a field hockey tournament. Twelve male hockey players were equipped with global positioning system (GPS) units while competing in an international tournament (six matches over 9 days). The following GPS-derived variables, total distance (TD), low-intensity activity (LIA; <15?km/h), high-intensity running (HIR; >15?km/h), high-intensity accelerations (HIACC; >2?m/s2) and decelerations (HIDEC; >?2?m/s2) were acquired and normalised to either (i) playing time, (ii) post-match RPE or (iii) both playing time and post-match RPE. Each morning, players completed ratings on a 0–10 scale for four variables: fatigue, muscle soreness, mood state and sleep quality, with cumulative scores determined as wellness. Associations between match performances and wellness were analysed using Pearson’s correlation coefficient. Combined time and RPE normalisation demonstrated the largest associations with Δwellness compared with time or RPE alone for most variables; TD (r?=??0.95; ?1.00 to ?0.82, p?=?.004), HIR (r?=??0.95; ?1.00 to ?0.83, p?=?.003), LIA (r?=??0.94; ?1.00 to ?0.81, p?=?.026), HIACC (r?=??0.87; ?1.00 to ?0.66, p?=?.004) and HIDEC (r?=??0.90; ?0.99 to ?0.74, p?=?.008). These findings support the use of wellness measures as a pre-match tool to assist with managing internal load over the course of a field hockey tournament.Highlights
Fixtures during international field hockey tournaments are typically congested and impose high physiological demands on an athlete. To minimise decrements in running performance over the course of a tournament, measures to identify players who have sustained high internal loads are logically warranted.
The present study examined the association between changes in simple customised psychometric wellness measures, on changes in match running performance normalised to (i) playing time, (ii) post-match RPE and (iii) playing time and post-match RPE, over the course of a field hockey tournament.
Changes in match running performance were better associated to changes in wellness (r = ?0.87 to ?0.95), when running performances were normalised to both time and RPE compared with time or RPE alone.
The present findings support the use of wellness measures as a pre-match tool to assist with managing internal load over the course of a field hockey tournament. Improved associations between wellness scores and match running performances were evident, when running variables were normalised to both playing time and post-match RPE.
Drawing from contemporary social science studies on the shifting regime of research governance, this paper extends the literature
by utilizing a metaphoric image—research is a game—observed in a field engagement with 82 American, British, and Danish crop
and plant scientists. It theorizes respondents’ thinking and practices by placing the rules of the research “game” in dynamic
and interactive tension between the scientific, social, and political-economic contingencies that generate opportunities or
setbacks. Scientists who play the game exploit opportunities and surmount setbacks by adopting strategies and reinventing
tactics in order to maximize their winnings and to minimize their losses. Winners become superstars who decree what is open,
closed, or doable science for the majority of the scientific community. 相似文献
YouTube has become a global platform for learning and teaching. Its design as a social medium, its rapidly growing content and the obscurity of its search and recommendation system, however, frequently leave users with suboptimal results. Trying to give guidance, many professional websites started to publish ranked lists of educational channels. These lists, however, are highly non-conjoint and different in length, which challenges their general usefulness. This study first highlights some aspects and issues related to ranking YouTube’s educational channels by a qualitative and quantitative analysis of 193 lists collected from 101 websites. Then, an iterative multi-algorithm approach is proposed to derive aggregated ranked lists starting from these online lists for three categories: general education, science and history. The aggregated lists were then correlated with surface features of the channels including the channel’s lifetime and the total number of videos, views and subscribers. Also, an alternative rating-based ranking was established by analysing a total of 2900 videos from the different channels. The results show that the aggregated ranked list of science channels has strong correlation with surface channel features. In contrast, the aggregated ranks of history channels are more correlated with viewers’ positive ratings. The aggregated ranks of general education channels neither relate to channel features nor to viewers’ ratings. Based on these findings several remarks and recommendations for the generation, usage, and research on ranked lists and rank aggregation of YouTube’s educational channels are given.
Abstract This paper examines, by way of case studies, the influence of traditionalism as a style of thought on the administration of Muslim law on divorce in the Syariah Court of Singapore. It focuses on the mode of its operation in the selection, construction and application of the law, and highlights its repercussions on the lives of parties in family breakdowns. The paper also touches upon the effects of traditionalism on the development of a more progressive legal culture and identifies measures that would alleviate the problem. 相似文献
