One prominent approach in the exploration of the variations in project team performance has been to study two components of the aggregate personalities of the team members: conscientiousness and agreeableness. A second line of research, known as self-categorisation theory, argues that identifying as team members and the team's performance norms should substantially influence the team's performance. This paper explores the influence of both these perspectives in university software engineering project teams. Eighty students worked to complete a piece of software in small project teams during 2007 or 2008. To reduce limitations in statistical analysis, Monte Carlo simulation techniques were employed to extrapolate from the results of the original sample to a larger simulated sample (2043 cases, within 319 teams). The results emphasise the importance of taking into account personality (particularly conscientiousness), and both team identification and the team's norm of performance, in order to cultivate higher levels of performance in student software engineering project teams.  相似文献

Circulating tumor cells (CTCs) are found in the blood of patients with cancer. Although these cells are rare, they can provide useful information for chemotherapy. However, isolation of these rare cells from blood is technically challenging because they are small in numbers. An integrated microfluidic chip, dubbed CTC chip, was designed and fabricated for conducting tumor cell isolation. As CTCs usually show multidrug resistance (MDR), the effect of MDR inhibitors on chemotherapeutic drug accumulation in the isolated single tumor cell is measured. As a model of CTC isolation, human prostate cancer cells were mixed with mouse blood cells and the label-free isolation of the tumor cells was conducted based on cell size difference. The major advantages of the CTC chip are the ability for fast cell isolation, followed by multiple rounds of single-cell measurements, suggesting a potential assay for detecting the drug responses based on the liquid biopsy of cancer patients.  相似文献

This case study presents a longitudinal, evidence‐based approach to health science curriculum reform and evaluation. Curriculum in higher education must meet the needs of diverse stakeholders and must respond to dynamic local, national and international contexts, and this creates challenges for evaluation. The long lead time prior to the introduction of new or revised university curriculum (at least two years), the length of degree programmes (three to five years) and the lag time in the availability of objective indicators of degree outcomes (at least one year post‐graduation) mean that findings may be obsolete before an evaluation can be completed. Few would argue that evaluation is important and methods and approaches for conducting curriculum evaluation are proposed in the literature, although few published reports of the outcomes of comprehensive evaluations are evident. This paper discusses potential for evaluation to establish responsive communication between students, teaching staff and programme administrators, ensuring a match between the intended, implemented and attained curriculum.  相似文献

Research on the roles of the board of unitary board systems is well established, while explorations of dual board systems are very limited. We know little about nonprofit sport organisations board roles in countries such as Taiwan that operate with a dual board structure. In consequence, this study explored the roles taken by the board of directors and the board of supervisors in Taiwanese nonprofit sport organisations. Four overarching board of director roles were identified: manage vision and purpose; board duty; human resource and fundraising; and stakeholder focus. For the board of supervisors two primary functions emerged: monitoring results; and board duty and process. The findings of the study extend our understanding of the governance of nonprofit sport organisations and the differences that exist between dual board and single board systems of governance.  相似文献
