从合理化角度回顾了当前几种重要的骨折治疗理论体系的发展与演变,认为骨折治疗的最优原则是一种理想状态,现实中没有绝对最优只有相对合理.只有建立以患者为中心的思维体系,加强医疗逻辑思维能力,用多维思考的方式寻找矛盾的合理平衡点,始终坚守医学伦理道德底线,才能真正做到为每一位骨折患者进行最合理的治疗. 相似文献

In the present study, 258 doctoral students working in the health, biological, and social sciences were asked to solve a series of field-relevant problems calling for creative thought. Proposed solutions to these problems were scored with respect to critical creative thinking skills such as problem definition, conceptual combination, and idea generation. Results indicated that health, biological, and social scientists differed with respect to their skill in executing various operations, or processes, involved in creative thought. Interestingly, no differences were observed as a function of the students' level of experience. The implications of these findings for understanding cross-field, and cross-experience level, differences in creative thought are discussed. 相似文献

Treatment packages including differential reinforcement of alternative (DRA) behavior and escape prevention in the form of a non‐removal of the spoon procedure have been shown to successfully increase food consumption. However, when these treatment components are introduced simultaneously, the treatment component(s) responsible for behavior change cannot be determined. The purpose of this study was to conduct a sequential component analysis of the following treatment components: Bite fading, manipulation of reinforcer magnitude, and escape prevention. For two participants, food consumption did not increase until after escape prevention was introduced. For one participant, increased food consumption was observed after the magnitude of reinforcement was increased; therefore, escape prevention was not necessary. Results were maintained at a 12‐week follow‐up for all participants. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

Terror management theory (TMT) proposes that people who are reminded of their mortality should be motivated to defend their cultural worldview. Studies 1 and 2 examined whether the TMT worldview defence‐buffering effect found in Western cultures could be generalized to Asians in Taiwan. No such effect was found in the present studies. This non‐significant result was robust when either a stronger distraction task was used (study 1) or when a subliminal manipulation of mortality salience was utilized (study 2). A meta‐analysis, including 24 TMT experiments in East Asia, was also conducted (study 3). The average effect size (d = 0.11, r = 0.055) of worldview defence among these experiments was not significantly different from zero. Study 4 found that mortality salience manipulation also did not change Taiwanese participants' view of reincarnation; however, it did make them more inclined to resign to fate, suggesting that they might be using this symbolic means to defend their anxiety of death. The issue of the generality of TMT to Asians was discussed. 相似文献

In this article I rethink death and mortality on the basis of birth and natality, drawing on the work of the Italian feminist
philosopher Adriana Cavarero. She understands birth to be the corporeal event whereby a unique person emerges from the mother’s
body into the common world. On this basis Cavarero reconceives death as consisting in bodily dissolution and re-integration
into cosmic life. This impersonal conception of death coheres badly with her view that birth is never exclusively material
but always has ontological significance as the appearance of someone new and singular in the world of relations with others.
This view of birth calls for a relational conception of death, which I develop in this article. On this conception, death
is always collective, affecting all those with whom the one who dies has maintained relations: As such, our different deaths
shade into one another. Moreover, because each person is unique in virtue of consisting of a unique web of relations with
others, death always happens to persons as webs of relations. Death is relational in this way as a corporeal, and specifically biological, phenomenon, to which we are
subject as bodily beings and as interdependent living organisms. I explore this with reference to Simone de Beauvoir’s memoir
of her mother’s death from cancer. Finally I argue that, on this relational conception, death is something to be feared. 相似文献

为探究面孔-词Stroop范式中的情绪冲突效应,本实验给被试呈现两种时长(150ms或1500ms)的刺激,令其分别完成对面孔-词Stroop范式中的“面孔任务”和“词任务”。结果发现:只有“面孔任务”中出现Stroop效应,产生情绪冲突,而在“词任务”中未出现Stroop效应;当呈现时间为150ms时,情绪词影响情绪面孔加工从而引发个体的情绪冲突,出现Stroop效应;当呈现时间为1500ms时,“面孔任务”中的Stroop效应消失。这提示了呈现时间是影响面孔-词Stroop范式中情绪冲突效应的一个重要因素。 相似文献

考察了16名22~34岁男性被试在45天-6°头低位卧床模拟失重条件下, 在卧床前(第2天)、卧床期(第11, 20, 32, 40天)及卧床后(第8天)的额区EEG偏侧化变化趋势, 并采用贝克焦虑量表(BAI)和贝克抑郁量表(BDI)对主观情绪状态进行评估。研究发现EEG偏侧化指标呈现出明显的线性变化趋势。卧床期间个体的心境状态处于比较低的水平, 报告有较强的躯体焦虑感。在整个卧床期间, 个体为维持稳定的情绪状态而付出比较大的情绪调节努力。 相似文献

The information content of panoramic images II: view-based navigation in nonrectangular experimental arenas 总被引:2,自引:0,他引:2

Two recent studies testing navigation of rats in swimming pools have posed problems for any account of the use of purely geometric properties of space in navigation (M. Graham, M. A. Good, A. McGregor, & J. M. Pearce, 2006; J. M. Pearce, M. A. Good, P. M. Jones, & A. McGregor, 2004). The authors simulated 1 experiment from each study in a virtual reality environment to test whether experimental results could be explained by view-based navigation. The authors recorded a reference image at the target location and then determined global panoramic image differences between this image and images taken at regularly spaced locations throughout the arena. A formal model, in which an agent attempts to minimize image differences between the reference image and current views, generated trajectories that could be compared with the search performance of rats. For both experiments, this model mimics many aspects of rat behavior. View-based navigation provides a sufficient and parsimonious explanation for a range of navigational behaviors of rats under these experimental conditions. 相似文献
