为检验同伴侵害影响儿童孤独感的中介变量,采用同伴提名、儿童自我知觉量表、儿童孤独感量表和班级戏剧问卷对武汉市某小学3-6年级445名儿童进行了调查。结果发现:同伴接纳和整体自尊是同伴侵害与孤独感间的两个中介变量。 在考察单一变量的中介作用时,同伴接纳在儿童的同伴侵害与其孤独感间起完全中介作用,而整体自尊在儿童的同伴侵害与其孤独感间起部分中介作用;当同时考察同伴接纳与整体自尊的中介作用时,同伴接纳与整体自尊在同伴侵害与孤独感间起完全中介作用,而且,由于同伴接纳对整体自尊的正向预测作用,同伴侵害对整体自尊的预测关系不显著。 相似文献

医生面对ICU临终患者很难抉择是应该积极治疗到底还是提供舒适的保守治疗,目前相关的伦理及法律问题仍尚需完善,伦理指导是一项解决纠纷、政善沟通有效的工具,成立伦理委员会对医生进行合理的建议和指导是非常必要的。 相似文献

We investigated how different numbers of responses prior to the presentation of a stimulus influenced preferences for the stimulus in three Japanese monkeys (Macaca fuscata). Monkeys were trained for two kinds of simultaneous discriminations that followed a high‐effort or a low‐effort response. In probe test trials, the stimulus that followed the high‐effort and the stimulus that followed the low‐effort response during discriminations were presented simultaneously. All monkeys chose stimuli that in training followed a low‐effort response. This result suggested that monkeys avoided stimuli that followed high‐effort responses because of the association between those stimuli and the preceding greater effort. The present result is consistent with our previous study conducted with humans, but contradicts analogous studies carried out with pigeons that reported either opposite results (i.e. pigeons preferred the stimuli after high‐effort) or non‐biased preferences. The differences between mammals and birds are discussed in terms of the lack of a successive negative contrast effect in birds. 相似文献

目的:考察工作伦理与工作满意度、离职意向的关系。方法:对252名企业员工进行工作伦理问卷调查,并建立结构方程模型考察工作伦理、工作满意度与离职意向的关系。结果:员工的工作伦理能显著预测离职意向(反向),工作满意在工作伦理对离职意向的影响中起着完全中介的作用。结论:企业在招聘员工的过程中要重视员工的工作伦理。 相似文献

电子产品改变了人们社会活动的模式和生活方式,其低龄化使用也不可避免地影响和塑造了儿童的发展。生态系统理论认为儿童的发展源于儿童与周围环境之间不断的交互作用。生态科技微系统理论是在当今电子科技的环境下以生态系统理论为背景框架提出的解释电子媒体对儿童发展影响的理论模型。电子产品作为儿童学习、娱乐、沟通和展示自我的工具,对儿童的认知方式、情感互动方式和参与社会的方式等都会产生一定的影响。这些影响依赖于三个相互独立又关联的因素之间的作用:儿童自身的特点、电子媒体的内容和特点,以及儿童媒体使用的环境。未来的研究可以从研究手段和研究内容上进一步深化以探讨电子产品的使用和儿童发展的关系。 相似文献

20世纪末的研究证据显示,对Navon等级刺激的整体/局部加工中半球功能不对称效应发生在早期还是晚期阶段,研究者存在着争论。近期的电生理和功能成像研究资料表明,整体/局部加工的半球不对称效应可能是一个受到多种因素调节的复杂动态系统;早期信息表征的半球功能不对称效应可能主要受知觉因素的影响,而注意控制和反应冲突可能主要调节晚期知觉加工的半球功能不对称 相似文献

It has become almost a truism to describe the interaction between research ethics committees and researchers as being marred by distrust and conflict. The ethical conduct of researchers is increasingly a matter of institutional concern because of the degree to which non-compliance with national standards can expose the entire institution to risk. This has transformed research ethics into what some have described as a research ethics industry. In an operational sense, there is considerable focus on modifying research behaviour through a combination of education and sanctions. The assessment of whether a researcher is ‘ethical’ is too often based on whether they submit their work for review by an ethics committee. However, is such an approach making a useful contribution to the actual ethical conduct of research and the protection of the interests of participants? Does a focus on ethical review minimise institutional risk? Instead it has been suggested that ethics committees may be distorting or frustrating useful research and are promoting a culture of either mindless rule following or frustrated resistance. An alternative governance approach is required. There is a need for a strong institutional focus on promoting and supporting the reflective practice of researchers through every stage of their work. By situating research ethics within the broader framework of institutional governance, this paper suggests it is possible to establish arrangements that actually facilitate excellent and ethical research. 相似文献

Nanotechnology, Enhancement, and Human Nature 总被引:1,自引:0,他引:1
Nicole Hassoun 《Nanoethics》2008,2(3):289-304
Is nanotechnology-based human enhancement morally permissible? One reason to question such enhancement stems from a concern for preserving our species. It is harder than one might think, however, to explain what could be wrong with altering our own species. One possibility is to turn to the environmental ethics literature. Perhaps some of the arguments for preserving other species can be applied against nanotechnology-based human enhancements that alter human nature. This paper critically examines the case for using two of the strongest arguments in the environmental ethics literature to show that nanotechnology-based human enhancements are impermissible: 1) Our species, like many other naturally occurring species, has aesthetic value. So, nanotechnology-based human enhancements that alter our species should be prohibited. 2) Our species plays valuable ecological roles. Nanotechnology-based human enhancements that alter our species are likely to interfere with our species playing our ecologically valuable roles. So, such enhancements should be prohibited. Neither argument, ultimately, proves conclusive. The paper concludes, however, that considerations underlying both arguments may show us that some nanotechnology-based human enhancements are impermissible. 相似文献

浅谈临终医疗的双重效应原则 总被引:1,自引:0,他引:1
双重效应原则常用于临终患者的治疗中,应用药物为患者解除痛苦,但可能导致患者严重不良反应甚至死亡,这在伦理上是可以接受的。但目前仍存在着较大争议,特别是如何认定医师的主观意图。 相似文献
