空心加压螺钉不同构型固定股骨颈骨折的生物力学研究

目的:用力学实验的方法,对倒、正等腰三角形布局的三枚空心加压螺钉固定头颈型股骨颈骨折进行生物力学比较,确定哪种空间构型生物力学性能好,从而为临床治疗股骨颈骨折提供理论依据.方法:用生物力学机测试比较倒、正等腰三角形空间构型抗压、抗扭性能及最大垂直载荷,实验数据用SPSS10.0统计软件进行t检验,P＜0.05有显著性差异.结果:倒等腰三角形构型在抗压、最大垂直载荷方面优于正等腰三角形组,有显著性差别;抗扭转方面无显著性差别.结论:实验结论支持治疗头颈型股骨颈骨折三枚空心加压螺钉倒等腰三角形构型生物力学效果好.     

Academics transformational leadership: an investigation of heads of department leadership behaviours in Malaysian public universities

Presently, the role and the function of universities in Malaysia have been described as being in a state of change. Several strategies have been adopted to assist in the re-branding of higher institutions of learning. As a consequence, an effective model of leadership practices, particularly at the Malaysian academic departmental level, has to be generated in order to replace the traditional leadership practices in meeting the national aspirations. The purpose of this study was to investigate the relationship between department heads’ leadership behaviour with academics’ organisational commitment. Survey responses from 430 academics from Malaysian public universities were received and analysed. The main finding of this study reveals that the adoption of encouraging leadership behaviour (Kouzes and Posner’s Transformational Leadership) shows a 55% direct positive relationship with academics’ organisational commitment, with demographical factors playing no role as a moderator with either variable. This reinforces the rationalisation for adopting the model within the Malaysian academic setting, where department heads should indeed lead the academic organisation.
