This paper explores the adoption of the scholarship of teaching and learning (SoTL) by 10 Malaysian university academics. SoTL was part of a pioneering sector-wide initiative for improving teaching and learning. The qualitative study showed that there had been no true learning phase for SoTL because academics had high expectations of rapid success in their new research area, including journal publication. Most of their peers did not understand or value SoTL and so SoTL researchers established minority self-sustaining groups across disciplines and universities. SoTL brought new ways of thinking about teaching that were transformational for the teacher but not necessarily welcomed by the students. Students resisted radical change, and teachers were drawn back to educational practices they no longer valued. SoTL was experienced in a hierarchical educational culture where questioning of self and others was difficult and this hindered teacher development. We conclude with recommendations about realistic expectations and the importance of social learning for those considering SoTL for academic development.  相似文献

This paper is concerned with the stability analysis problem for a class of delayed stochastic recurrent neural networks with both discrete and distributed time-varying delays. By constructing a suitable Lyapunov–Krasovskii functional, a linear matrix inequality (LMI) approach is developed to establish sufficient conditions to ensure the global, robust asymptotic stability for the addressed system in the mean square. The conditions obtained here are expressed in terms of LMIs whose feasibility can be checked easily by MATLAB LMI Control toolbox. In addition, two numerical examples with comparative results are given to justify the obtained stability results.  相似文献

This paper presents our work towards developing a new speech corpus for Modern Standard Arabic (MSA), which can be used for implementing and evaluating Arabic speaker-independent, large vocabulary, automatic, and continuous speech recognition systems. The speech corpus was recorded by 40 (20 male and 20 female) Arabic native speakers from 11 countries representing three major regions (Levant, Gulf, and Africa). Three development phases were conducted based on the size of training data, Gaussian mixture distributions, and tied states (senones). Based on our third development phase using 11 hours of training speech data, the acoustic model is composed of 16 Gaussian mixture distributions and the state distributions tied to 300 senones. Using three different data sets, the third development phase obtained 94.32% and 8.10% average word recognition correctness rate and average Word Error Rate (WER), respectively, for same speakers with different sentences (testing sentences). For different speakers with same sentences (training sentences), this work obtained 98.10% and 2.67% average word recognition correctness rate and average WER, respectively, whereas for different speakers with different sentences (testing sentences) this work obtained 93.73% and 8.75% average word recognition correctness rate and average WER, respectively.  相似文献

This paper addresses the issue of reliable feedback control of an uncertain aircraft flight control systems with disturbances via non-fragile sampled-data control approach. In particular, the parameter uncertainties are assumed to be randomly occurring which is described by the Bernoulli distributed sequences. By constructing a suitable Lyapunov–Krasovskii functional together with Wirtinger-based inequality, a new set of sufficient conditions in terms of linear matrix inequalities is obtained to ensure the asymptotic stability and extended dissipativity of the aircraft flight control systems not only when all actuators are operational, but also in case of some actuator failures. Finally, simulation results are conducted to validate the effectiveness of the proposed control design technique.  相似文献

Serum alpha-1-antitrypsin assay was carried out in 21 smokers (mean age 44±8 yrs) and in 25 nonsmokers (mean age 44±7 yrs). The levels of serum alpha-1-antitrypsin expressed in umol/mt/ml were 2.97±0.85 for smokers and 3.08±0.37 for non-smokers and analysis of variance revealed no significant difference between these two groups. However in five smokers reduced levels (<80% of the lower limit of non-smokers) were seen and four of them were bus drivers. This study advises monitoring of serum alpha-1-antitrypsin levels in smokers with possible therapy to those with reduced levels.  相似文献

This study aimed to investigate whether treadmill versus overground soccer match simulations have similar effects on knee joint mechanics during side cutting. Nineteen male recreational soccer players completed a 45-min treadmill and overground match simulation. Heart rate (HR) and rating of perceived exertion (RPE) were recorded every 5 min. Prior to exercise (time 0 min), at “half-time” (time 45 min) and 15 min post-exercise (time 60 min), participants performed five trials of 45° side-cutting manoeuvres. Knee abduction moments and knee extension angles were analysed using two-way repeated measures analysis of variance (α = 0.05). Physiological responses were significantly greater during the overground (HR 160 ± 7 beats ? min?1; RPE 15 ± 2) than the treadmill simulation (HR 142 ± 5 beats ? min?1; RPE 12 ± 2). Knee extension angles significantly increased over time and were more extended at time 60 min compared with time 0 min and time 45 min. No significant differences in knee abduction moments were observed. Although knee abduction moments were not altered over time during both simulations, passive rest during half-time induced changes in knee angles that may have implications for anterior cruciate ligament injury risk.  相似文献

Abstract

Purpose: Public-funded fisheries extension services have been blamed as poor and responsible for the slow pace of aquaculture development in India. The present investigation aimed to find concrete interventions to streamline the extension service by understanding the research-extension-farmer linkage indirectly in terms of information sources of aqua farmers and fishery extension officers and assessing the existing organizational, manpower and extension capabilities of Departments of Fisheries of sample states.

Design/methodology/approach: A random sample of 1008 brackishwater aqua farmers, a purposive random sample of 60 extension personnel and 45 researchers were interviewed to collect primary data for the study. A multidimensional Organizational Analysis Index was developed specifically for the study. The Wilcoxon paired rank test was employed to analyze and compare the perceptions of the fishery extension personnel.

Findings: The study revealed that 90% of aqua farmers depend on private extension sources for information; information-seeking by the extension personnel was less than 50%; and less than 50% of the researchers expressed having had consultations with the extension agencies. Results indicated that the respondents differ significantly over the existing and ideal organizational, manpower and extension attributes of the fisheries departments. An extension approach to evolve a National Fisheries and Aquaculture Extension Service (NFAES) to strengthen fisheries departments with structural and functional realignments and partnership with farm leaders and fisheries professionals is suggested in order to streamline the fisheries and aquaculture extension service in India.

Practical implications: The findings of the study may enlighten the fisheries development planners and provide indications to initiate attempts to streamline the fisheries extension departments for an effective extension service in India.

Originality/value: The study was originally conducted by the authors. Nothing similar has been previously published or is currently under consideration for publication by another journal.  相似文献
