Abstract

This article looks at some of the unconscious processes that operate among solicitors in general practice. In particular it considers various defences against the anxiety felt by solicitors partly because of the nature of their work and partly because of what is projected onto them by their clients. It argues that these defences have become embodied in the legal system itself as ‘socially structured defence mechanisms’ (Menzies Lyth 1989).  相似文献

SUMMARY

Persons in North America who are over 80 years of age are generally overlooked by religious leaders. They are, however, the fastest growing cohort in society. This age crescendo promises to be a significant factor in the future ministry of the rapidly increasing number of graying churches and synagogues.  相似文献

前摄干扰(PI)对工作记忆有决定性影响.注意加工理论认为处于工作记忆“注意焦点”的信息不受PI影响,偏向-竞争理论则提出个体对熟悉信息和情景信息代码做出权重评估,解决工作记忆PI效应.研究者从工作记忆编码和提取加工的PI效应、内容相关和情景相关的PI效应、PI消除的脑成像特征等角度进行了验证,多数结果支持偏向-竞争理论.未来研究应使用脑成像技术探讨PI效应与工作记忆子系统、子功能之间的关系等主题.  相似文献

Frequency-related response characteristics of the mechanisms controlling stabilization of the head in 10 elderly subjects were compared with response characteristics in 8 young adults. Angular velocity of the head with respect to the trunk and EMG responses of 2 neck muscles were recorded in 10 seated subjects during pseudorandom rotations of the trunk in the sagittal plane at frequencies of 0.35 to 3.05 Hz. Subjects were required to actively stabilize their heads with (VS) and without (NV) visual feedback so that voluntary mechanisms and the influence of vision could be tested. Reflex mechanisms were examined when subjects were distracted by a mental calculation task during rotations in the dark (MA). Age emerged as an influential factor in the performance of head stabilization mechanisms, and decrements in performance were even more pronounced in the older as compared with younger elderly subjects. Age effects could be seen in the (a) diminished ability to voluntarily stabilize the head, particularly with the absence of vision, (b) impaired ability to stabilize the head when cognitively distracted, and (c) appearance of a resonant response of the head. Control of head stabilization shifted from reflex mechanisms to system mechanics, probably as a result of age-related changes in the integrity of the sensory systems. The elderly's system mechanics could not effectively compensate for the disturbances, however, and instability was the result.  相似文献

The lead-lag structure of multivariate time-ordered observations and the possibility to disentangle between-person (BP) from within-person (WP) sources of variance are major assets of longitudinal (panel) data. Hence, psychologists are making increasing use of such data, often with the intent to delineate the dynamic properties of psychological mechanisms, understood as a sequence of causal effects that govern psychological functioning. However, even with longitudinal data, psychological mechanisms are not easily identified. In this article, we show how an adequate representation of time may enhance the tenability of causal interpretations in the context of multivariate longitudinal data analysis. We anchor our considerations with an example that illustrates some of the main problems and questions faced by applied researchers and practitioners. We distinguish between static versus dynamic and discrete versus continuous time modeling approaches and discuss their advantages and disadvantages. We place particular emphasis on different ways of addressing BP differences and stress their dual role as potential confounds versus valuable sources of information for improving estimation and aiding causal inference. We conclude by outlining an approach that offers the potential of better integration of information on BP differences and WP changes in the search for causal mechanisms along with a discussion of current problems and limitations.  相似文献

This psychobiographical study of Richard Trenton Chase (1950–1980), a serial murderer, has the aim to uncover the psychic mechanisms characteristic of his functioning. The study included primary and secondary data sources. All materials collected and analysed, were published and publically available. The Schahriar syndrome model served as the conceptual framework for data framing and interpretation. Findings suggest that Chase exhibited five primitive psychic mechanisms namely: omnipotence, sadistic fantasies, ritualised performance, dehumanisation and symbiotic merger. The Schahriar syndrome model has utility to explain the psychological functioning of a serial murderer.  相似文献

药物性肝损伤(DILI)可分为直接肝毒性和特异质性肝损伤(IDILI).IDILI发生率较低,个体发病存在易感因素,在动物模型中很难复制.同时,IDILI缺乏可靠的临床诊断标准,使其发病机制的研究受到限制.近年来关于IDILI的发病机制,主要在遗传易感性、代谢途径、宿主免疫、线粒体毒性和胆道损伤等方面取得进展,各种发病机制的深入研究和相互关系的阐明,或将揭示IDILI的真正致病机制.  相似文献

The mechanical behaviour of polycrystalline hexagonal close-packed cobalt was investigated over a large range of grain size d in order to examine the occurrence of size effects. Crystallographic texture and amount of face centred cubic allotropic phase were maintained unchanged thanks to appropriate heat treatment procedures. The Hall–Petch (HP) relation exhibits two distinct behaviours from the very beginning of plastic strain levels. The conventional HP law is fulfilled for a number of grains across the thickness t higher than a critical value (t/d)c = 14. For t/d lower than (t/d)c, a multicrystalline regime is evidenced highlighting a strong reduction in flow stress. The high value of (t/d)c is related to the low-stacking fault energy of cobalt in the basal plane. The size effect is predominant in the first work hardening stage where slip mechanisms and stacking faults predominate. In the second stage, driven by mechanical twinning processes, this effect is less sensitive. Finally, the size effect could also affect the end of the elastic stage, in link with nonlinear elasticity mechanisms.  相似文献
