骨折治疗方法与原则的最优化历程 总被引:3,自引:0,他引:3
多年来骨折治疗,新旧技术、新旧理论相互融合,相互碰撞,产生了新的理论和方法,使得临床疗效显著提高,现阶段理智的临床医生应该融汇各家之长,多方互补,对每一位骨折患者的治疗都应该按照最优化的原则进行.但是在医疗过程中总存在着如方法选择不当或者错误,过度治疗,医患信任危机,医疗伦理道德的丧失等情况,我们应该用矛盾分析的方法来思考这些问题. 相似文献

University students were trained to discriminate between two gray-scale images of faces that varied along a continuum from a unique face to an average face created by morphing. Following training, participants were tested without feedback for their ability to recognize the positive face (S+) within a range of faces along the continuum. In Experiments 1 and 4, the range of stimuli presented during testing was manipulated. In Experiment 2, participants viewed different ranges of faces during an adaptation period that followed training and preceded testing. In all experiments, generalization functions revealed peak shifts or area shifts (fewer “yes” responses to novel faces on the negative side of the S+), but no systematic effects of the test or adaptation range. Peak shift was found both for upright and inverted faces and occurred even if the orientation of the face was reversed between training and test. Using similar methods, either an area shift or range effect (but not both together) was demonstrated for line tilt stimuli (Experiment 3), and the appearance of these effects depended on instructions. It appears that peak shift and area shift are robust across many different kinds of stimuli, but range effects may not readily occur with complex multidimensional stimuli. 相似文献

The purpose of the present study was to investigate the relationships between employee categorization criteria and Chinese managers' allocation behaviors. Using a vignette approach and a four-factor within-subjects design, the effects of relationship (guanxi), loyalty, and competence, as well as their interactions with allocation context (private vs public) were examined. Results showed that subordinates who had a close relationship with the allocator, high loyalty, or high competence were rewarded more. Significant two-way interaction effects indicated that relationship, loyalty and competence interactively affected Chinese managers' reward allocation decisions. In addition, the moderating effects of allocation context on these three criteria were also significant. Limitations of the study and suggestions for further research were discussed. 相似文献

本研究以小学五年级292名学生为对象,考察了三种思维训练方式(元认知内隐训练、元认知外显训练和一般思维策略训练)对三种不同认知方式学生(场独立型、场依存型和中间型)数学应用题解题能力的影响。结果发现:(1)思维策略的元认知外显训练和元认知内隐训练比一般思维策略训练能蜓有效地提高场依存型、中间型和场独立型三类学生的应用题解题能力:(2)元认知外显训练和内隐训练对于场独立型和中间型学生同等重要。但元认知外显训练更有助于场依存型学生应用题解题能力的提高。成为该类学生的优势圳练方式;(3)在小学五年级.场独立型学生的应用题解题能力明显优于场依存型学生的应用题解题能力。 相似文献

Neuronal synchronisation at gamma frequencies (30-100 Hz) has been implicated in cognition and memory. Gamma oscillations can be studied in various in vitro models, but their in vivo validity and their relationship with reference memory remains to be proven. By using the natural variation of wild type C57bl/6J mice, we assessed the relationships between reference memory and gamma oscillations recorded in hippocampal area CA3 in vivo and in vitro. Local field potentials (LFPs) were recorded from area CA3 in behaviourally-characterised freely moving mice, after which hippocampal slices were prepared for recordings in vitro of spontaneous gamma oscillations and kainate-induced gamma oscillations in CA3. The gamma-band power of spontaneous oscillations in vitro correlated with that of CA3 LFP oscillations during inactive behavioural states. The gamma-band power of kainate-induced oscillations correlated with the activity-dependent increase in CA3 LFP gamma-band power in vivo. Kainate-induced gamma-band power correlated with Barnes circular platform performance and object location recognition, but not with object novelty recognition. Kainate-induced gamma-band power was larger in mice that recognised the aversive context, but did not correlate with passive avoidance delay. The correlations between behavioural and electrophysiological measures obtained from the same animals show that the gamma-generating capacity of the CA3 network in vitro is a useful index of in vivo gamma strength and supports an important role of CA3 gamma oscillations in spatial reference memory. 相似文献
