心脏死亡器官捐献的困境及对策

心脏死亡供体作为增加器官来源的重要途径;已受到世界移植界的广泛关注.在我国特殊的移植环境中;心脏死亡器官捐献的开展有其优势;但也面临着伦理、技术及社会方面的困境.除了要加大宣传力度;树立新观念外;还应培训器官捐献协调员;建立合理的补偿机制;树立医院良好形象;促进器官捐献不断发展.

Precipitate characteristics and selected area diffraction patterns of the β′ and Q′ precipitates in Al–Mg–Si–Cu alloys

In this study, the precipitate characteristics and selected area diffraction patterns (SADP) of the β?′ and Q?′ precipitates formed at the over-aged state of Al–Mg–Si–Cu alloys are systematically investigated by means of high-resolution transmission electron microscopy and transition matrix. The β?′ precipitates have two cross-sections, rectangle-shaped and round-shaped aligned with [0?0?1]_Al direction, but only rectangle-shaped cross-section exists for Q?′ precipitates. And, both of them have 12 variants and orientations with Al matrix. However, there are only three different zone axes, [0?0?0?1]_β?′, [1?4?5?0]_β?′, and [5?4?1?0]_β?′ for β?′ precipitates, and [0?0?0?1]_Q?′, [1?4?5?0]_Q?′, and [3?2 1?0]_Q?′ for Q?′ precipitates, parallel to the [0?0?1]_Al direction when they are precipitated from the Al matrix, respectively. Then, a new [0?0?1]_Al SADP model, which superposes diffraction patterns of the β?′ and Q?′ precipitates, is established. Furthermore, some “cross-shaped” diffraction streaks appeared at over-aged state can be explained reasonably by this model, which is good in agreement with the experimental data.     

Coming to America for Spiritual or Academic Growth? Experiences of International Students at One Christian School

The number of international students flocking to North American private Christian schools has continued to grow. The author examined the overall experiences of 67 international high school students studying at a private Christian school in South Carolina. Their frustrations and struggles with academic and spiritual growth in a new cross-cultural setting, their reasons for coming to study in the United States at their own expense, as well as their motivations to come to the United States were investigated. The findings signified that none of the participants came to the Christian school for a Christian education, but for a good academic education and a bright future. In addition, the absence of their home cultures, the lack of academic language, and the large culture distance contributed to their frustrations and struggles in the process of adaptation to the new school environment.

关于医院伦理委员会监管研究的文献分析

检索2005年1月～2012年6月讨论伦理委员会监管问题的论文,利用文献研究的方法,对历年发文篇数变化情况、发文地区、作者所属机构、发表物、引证情况、监管内容等方面进行整理分析.结果表明,对伦理委员会监管制度的研究尚处于初始阶段,研究内容集中在监管主体、运作机制、法律法规、认证制度四个方面.     

具身认知视角下的概念隐喻理论

隐喻是一种常见的语言现象.概念隐喻理论认为,隐喻不仅是一种语言修辞手段,隐喻反映了人类认知的重要特征:人类的抽象概念系统是以感知觉经验和具体概念为基础发展形成的.根据概念隐喻理论,主体可以以感知运动经验对抽象概念进行体验式表征与加工.大量研究证明,抽象概念的加工同对其进行隐喻化描述的身体经验具有关联.这些研究主要涉及空间隐喻、温度隐喻、洁净隐喻、触觉隐喻等.未来的研究应探讨多重隐喻对认知的影响、探索塑造隐喻映射单向作用与相互作用的因素,并关注概念隐喻理论的应用性等问题.     

偏题言语及其老化机制

在日常生活中,相比年轻人,老年人的话语总是更容易偏离当前话题,而且内容比较冗余,这种现象就是偏题言语的老化。语用改变假设认为是老年人沟通目标的改变导致其偏题言语的增多,该理论能够一定程度地解释在自传式话题上的偏题现象,但很难解释在不涉及沟通目标改变的任务上出现的偏题言语。抑制缺陷理论则认为老年人的偏题言语与其在抑制无关信息能力上的缺陷密切相关,该理论虽然可以解释在一般话题上出现的偏题言语,但没有将抑制在偏题言语老化现象上的作用机制阐释得很清楚。未来研究应着重探讨偏题言语的具体老化机制,以期为改善老年期的偏题言语现象提供更有效的措施。     

社会支持对青少年创伤后成长的影响:状态希望和积极重评的中介作用

采用创伤暴露程度问卷、社会支持问卷、状态希望量表、认知情绪调节量表和创伤后成长问卷,以雅安地震2.5年后的397名中学生为被试,考察其社会支持、状态希望、积极重评与创伤后成长（PTG）之间的关系。结果发现,雅安地震2.5年后青少年的社会支持可以直接正向预测PTG,不过,在社会支持与PTG之间纳入状态希望和积极重评后,社会支持不能直接地促进PTG,但却可以分别通过状态希望和积极重评来促进PTG,还可以经过状态希望由积极重评的多重中介来正向预测PTG。
