The study examined psychosocial work-conditions and physiological reactions among thirty-six police inspectors (median age 45 years, 81% males) who participated in a reorganization. At this time, subjects were threatened by unemployment and had to re-apply for their positions in a new police district. Data were collected during the reorganization and at three years follow-up, by means of questionnaires (Stress Profile) and blood samples. The blood samples were used to determine serum levels of gamma-glutamyltransferase (GGT), glucose, lipids, prolactin, testosterone and cortisol. The results show a positive association between worry about employment and symptoms of burnout during the reorganization. Mean scores for the Stress Profile sub-scales worry about employment (p<.01) and work-load (p<.05) decreased between measurements, but an impairment in relationships with management was noticed (p<.05). No significant changes were observed in terms of self-rated health complaints. Significant decreases in total cholesterol (p<.0001), LDL-cholesterol (p<.0001), LDL/HDL-ratio (p<.01), prolactin (p<.0001), as well as increases in testosterone (p<.01) and cortisol (p<.001) were observed for the whole sample. Glucose decreased with marginal significance (<.07). Controlling for age and gender, multivariate regression analyses showed that subjects who reported deteriorations in satisfaction with work manifested the most modest decreases in prolactin (p<.05). Also, the decrease in glucose was larger for subjects who experienced impairments in satisfaction with work (p<.05), information (p<.05), task-oriented leadership, (p<.05), and respect and dignity (p<.05). Subjects who perceived deteriorations in the ethical and moral standards of the organization increased their cortisol level to a lower degree than their counterparts (p<.05). Favorable changes in employment status and psychosocial work environment seem to be related to improved physiological functioning.  相似文献

As part of the International Self-Identity Research Project, this study explored sources of identity among Turkish adolescents. The interview sample consisted of three male and three female high school students in Ankara, Turkey. The results indicated that social, familial, personal, physical, and moral-ethical dimensions contributed to adolescents' definitions of self, but to different degrees. Social and familial dimensions were very influential and were used as reference points for defining self in other areas. Physical and personal aspects of identity were also apparent, but were not as salient as social and familial dimensions. Patriotism and religion played a role in moral-ethical identity. Overall, self-identity influenced emotional state, cognitive and behavioral functioning, and social relations to a significant degree.  相似文献

Can there be rules of language which serve both to determine meaning and to guide speakers in ordinary linguistic usage, i.e., in the production of speech acts? We argue that the answer is no. We take the guiding function of rules to be the function of serving as reasons for actions, and the question of guidance is then considered within the framework of practical reasoning. It turns out that those rules that can serve as reasons for linguistic utterances cannot be considered as normative or meaning determining. Acceptance of such a rule is simply equivalent to a belief about meaning, and does not even presuppose that meaning is determined by rules. Rules that can determine meaning, on the other hand, i.e., rules that can be regarded as constitutive of meaning, are not capable of guiding speakers in the ordinary performance of speech acts.  相似文献

The present article critically examines three aspects of Graham Priest's dialetheic analysis of very important kinds of limitations (the limit of what can be expressed, described, conceived, known, or the limit of some operation or other). First, it is shown that Priest's considerations focusing on Hegel's account of the infinite cannot be sustained, mainly because Priest seems to rely on a too restrictive notion of object. Second, we discuss Priest's treatment of the paradoxes in Cantorian set-theory. It is shown that Priest does not address the issue in full generality; rather, he relies on a reading of Cantor which implicitly attributes a very strong principle concerning quantification over arbitrary domains to Cantor. Third, the main piece of Priest's work, the so-called “inclosure schema”, is investigated. This schema is supposed to formalize the core of many well-known paradoxes. We claim, however, that formally the schema is not sound. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

Zusammenfassung. Im Vorfeld der Diskussionen1über den inzwischen in Kraft getretenen § 174 c StGB wird einer pauschalen P?nalisierung von sexuellen Beziehungen im Kontext von Psychotherapien widersprochen. Anhand der „chronique scandaleuse“ von Krutzenbichler und Essers wird dargelegt, da? es seit den Anfangszeiten der Psychoanalyse bis heute immer wieder „Analysezwischenf?lle“ solcher Art gegeben hat. An einem Fallbeispiel wird darüber hinaus aufgezeigt, da? die Sch?dlichkeit intimer Kontakte differenziert betrachtet werden mu?. Der Beitrag mündet in eine „Psychoanalyse der analytischen Situation“: statt nach dem Gesetzgeber zu rufen, sollten die Psychoanalytiker das Problem als ein der psychoanalytischen Situation von ihrer Konstruktion her inh?rentes erkennen und analysieren.
Love in psychoanalysis – a case for the public prosecutor?
Summary. This essay protests in the course of the discussions about § 174c StGB that in the meantime came to effect, against a general penalization of sexual contacts in the context of psychotherapy. On the basis of the “chronique scandaleuse” of Krutzenbichler and Essers it is showed, that since the beginnings of psychoanalysis up till today there occurred repeatedly such “incidents in analysis”. A case study helps to show, that the harm of intimate contacts has to be considered with great differentiation. The article's conclusion is a “psychoanalysis of the analytical situation”: instead of calling for the legislative psychoanalysts should recognize and analyse the problem as an inherent one rooted in the construction of the psychoanalytic situation itself.

When subjects are asked to determine where a fast-moving stimulus enters a window, they typically do not localize the stimulus at the edge, but at some later position within that window (Fröhlich effect). We report five experiments that explored this illusion. An attentional account is tested, assuming that the entrance of the stimulus in the window initiates a focus shift toward it. While this shift is under way, the stimulus moves into the window. Because the first phenomenal (i.e., explicitly reportable) representation of the stimulus will not be available before the end of the focus shift, the stimulus is perceived at some later position. In Experiment 1, we established the Fröhlich effect and showed that its size depends on stimulus parameters such as movement speed and movement direction. In Experiments 2 and 3, we examined the influence of eye movements and tested whether the effect changed when the stimuli were presented within a structural background or when they started from different eccentricities. In Experiments 4 and 5, specific predictions from the attentional model were tested: In Experiment 4 we showed that the processing of the moving stimulus benefits from a preceding peripheral cue indicating the starting position of the subsequent movement, which induces a preliminary focus shift to the position where the moving stimulus would appear. As a consequence the Fröhlich effect was reduced. Using a detection task in Experiment 5, we showed that feature information about the moving stimulus is lost when it falls into the critical interval of the attention shift. In conclusion, the present attentional account shows that selection mechanisms are not exclusively space based; rather, they can establish a spatial representation that is also used for perceptual judgment—that is, selection mechanisms can bespace establishing as well.  相似文献

Conclusion The cultural characteristics of any country generally give shape to the educational system. However, no country can assert its own educational system to be wholly indigenous. All the systems come into being as a synthesis of various ingredients of the home country and other countries. And it is quite natural to make use of the experiences and stock of knowledge of the others. This fact is indispensable especially when education is concerned. The curicial problem is to what extent the borrowing process should be used. When the process of borrowing ideas become to take the form of imitation or copy, unexpected results and failure are unavoidable.  相似文献

In many current theories of human sentence processing, the mechanisms and principles proposed to account for data related to processing (1) long-distance dependencies and (2) structural ambiguities, such as garden-path sentences, are independent, despite the fact that deciding whether or not to posit a gap is just a special case of ambiguity resolution. In this paper we demonstrate how the parallel parsing theory proposed by Gibson (1991, in press)—which was developed to account for nongap ambiguity resolution data—also explains a number of gap-positing facts, without additional strategies. In particular, we show how this theory correctly explains filled-object-gap effects and the lack of filled-subject-gap effects in English, as well as certain gap-processing effects in Dutch.  相似文献
