Advance health care directives and informed consent remain the cornerstones of patients' right to self-determination regarding medical care and preferences at the end-of-life. However, the effectiveness and clinical applicability of advance health care directives to decision-making on the use of life support systems at the end-of-life is questionable. The Uniform Anatomical Gift Act (UAGA) has been revised in 2006 to permit the use of life support systems at or near death for the purpose of maximizing procurement opportunities of organs medically suitable for transplantation. Some states have enacted the Revised UAGA (2006) and a few of those have included amendments while attempting to preserve the uniformity of the revised Act. Other states have introduced the Revised UAGA (2006) for legislation and remaining states are likely to follow soon.  相似文献

身体映像对个体的身心发展有重要的意义, 对它的研究在近20年来更是如火如荼地发展。根据布朗芬布伦纳的生态系统理论, 从微系统(父母、同伴、伴侣)、外系统(媒体)、宏系统(社会文化)以及处于系统中的个体因素四个方面, 对影响身体映像的因素进行初步的分类和归纳, 为身体映像的干预措施提供参考。  相似文献

我是第一次来五台山,感触特别深,第一是省、市领导的人文素质特别高,对整个五台山的研究工作支持很大,尽管我第一次来五台山,但我与五台山结缘可能有十多年了,事实上,我在读博士的时候就开始写关于五台山的文章,并在《五台山研究》上发表。因此说结缘较早。佛家常说,三十年看山是山,看水是水,再过三十年看山不是山,看水不是水。三十年后又是看山是山,看水是水,这是一个认识不断深化的过程。五台山既有很壮丽的自然景观,也有历史悠久的人文景观,是个历史与自然的二重体,这就是向外对话的一个很好的条件。自然景观在于保护和利用,而人文景观在于重建  相似文献

以442名初中生为被试,采用历时20个月的纵向研究考察家庭社会经济地位(socioeconomic status, SES)和积极品质对中考成绩的预测作用。结果发现:(1)家庭SES、积极品质整体发展水平可以同时显著正向预测初中生在20个月后的中考成绩;(2)积极品质整体发展水平在家庭SES与中考成绩之间存在中介作用,即家庭SES越高,初中生的积极品质整体水平越高,其中考成绩越好。研究结果提示积极品质可以补偿低家庭SES对学生中考成绩的不良影响。  相似文献

支持型领导行为在工作压力模型中的作用机制研究   总被引:3,自引:0,他引:3  
本研究调查了 1 3个企业共 2 1 8位员工 ,探讨了支持型领导行为在角色冲突、人际冲突、缺乏成就与发展 (压力源 )和工作满意感、工作焦虑 (压力反应 )之间的作用机制。研究发现 :(1 )支持型领导行为对工作满意感和工作焦虑有主效应 ,但是由于逆向缓冲的存在 ,支持型领导行为的主效应并不总是对的 ,我们必须在更大的范围中考虑领导行为的效应 ;(2 )缓冲效应的六个假设只有一个被证明 ,但是方向相反 ,即支持型领导行为加剧了由人际冲突造成的工作不满意感 ;(3)两个中介模型的部分关系被证明 ,但是我们很难确定是支持型领导行为的弱化效应还是评价作用。为了更好地说明因果关系 ,在将来的研究中纵向研究设计被认为更为恰当。  相似文献

Ninety soldiers with at least three months of combat exposure—60 injured soldiers (30 with permanent disabling and 30 with nondisabling injuries), 30 noninjured soldiers and 30 healthy controls—were interviewed and investigated with physiological (Prolactine, Cortisol, BP, Hb) and psychological tests (MMPI), IES-15 (Impact of Event Scale), PTSS (Post-Traumatic Symptom Scale). Their was related injuries had a different effect on the physiological stress response of the soldiers as reflected in the levels of prolactine, cortisol, hemoglobin and blood pressure. In a report of personality characteristics of the same soldiers, we demonstrated that the experience of posttraumatic stress was not dependent upon physical injury, but rather on the psychological appraisal of the situation. The results of the present article confirm earlier findings that the relationship between physiological and psychological consequences of trauma are complex, and that the perception of an event and the social context within which the traumatized soldier exists is as important as the event itself. The physiological response to the trauma varied greatly among the soldiers regarding the psychosocial impact of the consequence of the injury. So the anticipation of future possible trauma among less severely wounded soldiers (expected to go back to war) was followed by pathological stress responses. Trauma seems to operate somewhat independently from the overt conscious appraisal of the situation and relationship between psychological, psychosocial, and physiological aspects are interrelated in a multifactorial way. An integrative approach is therefore of great importance in assessment as well as in treatment of Posttraumatic Stress Disorder (PTSD). Editorial Note This historical article is being published for the first time. It is based on the Ph.D. thesis of Dr. Harry A. Teitelbaum for which he was awarded a doctorate by the University of Maryland in College Park in 1936. The dissertation was stored prior to publication and was not rediscovered until 1997. Teitelbaum’s work was performed during the early days of the development of knowledge regarding the mechanisms that regulate endocrine function. The understanding of the broad capability of interactions among endocrine glands was evolving. It was a field that Teitelbaum contributed to for several years, many of which were spent in collaboration with Horsley Gantt in his laboratory at Johns Hopkins. Although some of the experimental strategies and some of the wording of the report seem quaint today, the contribution of Teitelbaum’s research was solid and highly relevant to questions being asked at the time.  相似文献

Both spouses of 100 married, heterosexual couples completed the Personal Authority in the Family System Questionnaire (PAFS-Q). A cluster analysis of the couples' scores on the four intimacy and fusion scales of the PAFS-Q produced four clusters that were meaningfully distinct in the patterns of differentiation of the wives and husbands. Couples comprising these clusters are described in terms of intergenerational theories of family interaction.This paper is based on the master's thesis of the first author submitted to the Graduate School of Texas Woman's University. A presentation based on this work was given at the 1988 annual convention of the Southwestern Psychological Association, Tulsa, Oklahoma. The authors thank Glenda Peters and Joe Natale for their contributions to the preparation of this paper. A more extensive report of the methodology and results of this study can be obtained from the second author.  相似文献

For first order languages with no individual constants, empty structures and truth values (for sentences) in them are defined. The first order theories of the empty structures and of all structures (the empty ones included) are axiomatized with modus ponens as the only rule of inference. Compactness is proved and decidability is discussed. Furthermore, some well known theorems of model theory are reconsidered under this new situation. Finally, a word is said on other approaches to the whole problem.  相似文献

一、問題 在現代生产技术中,人和机器可以看作是一个統一的系統。这一系統的中心环节是人。人凭借自己的感官从仪表和信号得到有关机器的运轉状态和生产过程的变化的信息,經过一系列的思惟活动,然后作出判断,并通过操作活动对机器和生产过程进行控制和調节。关于人和机器的这一方面的关系,以及关于机器、仪表、信号和操纵装置的設計如何适应人的感知、思惟和运动的特点,以便使“人机系統”达到最高效率的研究,已經形成一个新的学科分支,即“工程心理学”。本研究所涉及的閃光信号的頻率选择問題,就是属于工程心理学的范围。  相似文献

一、汉語拼音方案的科学性及优越性 汉語拼音方案是利用拉丁字母和北京音組織起来的中国化的文字的基础。汉語拼音字母中的复韵母和鼻韵母是由两个或两个以上的单韵母組成的。除开带ng的鼻韵母本身較难拼音之外其余的复韵母本身都可以进行拼音的。所以在拼音字母中,只要掌握26个(实际应用是25个)名称音的字母之后,其余的复韵母和鼻韵母几乎都可以利用邏輯記忆  相似文献
