This note concerns two issues left unresolved in our study of lexicographic‐order preservation and stochastic dominance in settings where preferences are represented by utility vectors, ordered lexicographically, and judgements emerge as matrices that premultiply utility vectors in expected utility sums. First, a generalization of the ‘Conjecture Σ’, which implied transitivity of a stochastic dominance relation under non‐vacuous resolution‐level information, is proved. Second, this paper comments on using resolution‐level information in higher as well as in first degree stochastic dominance analysis. Copyright © 1999 John Wiley & Sons, Ltd.  相似文献

Several programming models are introduced with the consideration of available unascertained information. In this case, the so‐called unascertained information is some numerical values whose ranges are known but their exact values are not. These models resolve several vital weaknesses of the traditional programming methods to a certain degree. Our study includes considerations of linear and non‐linear programming models with grey parameters, grey 0–1 programming, and satisfactory and quasi‐optimal solutions of grey linear programmings. Finally, some practical applications are given in order to test the applicability of our theory. Copyright © 1999 John Wiley & Sons, Ltd.  相似文献

The early development of infant non‐distress vocalizations was investigated in this study. Thirteen infants, from 4 to 24 weeks of age, and their mothers were observed weekly in a face‐to‐face interaction situation. The speech quality (syllabic versus vocalic) and melodic complexity (simple versus complex) of infant vocalizations were coded independently. Based on speech quality and melodic complexity, four types of infant non‐distress vocalizations were categorized: simple and complex syllabic (speech‐like) vocalizations as well as simple and complex vocalic (non‐speech‐like) vocalizations. Results showed that complex syllabic sounds were of longer duration and complex vocalic sounds were less frequent than the other types of vocalizations. Curvilinear developmental trends were found in the rate of simple vocalic sounds and in the mean duration of complex syllabic sounds. Furthermore, before 4 months of age, vocalic sounds were more likely to be associated with simple melodic contours, after which syllabic sounds were more likely to be associated with complex melodic contours. A dynamic systems perspective on the early development of infant vocalization is discussed. Copyright © 2000 John Wiley & Sons, Ltd.  相似文献

非稳态噪声对动物行为及心脏自由基损伤的影响   总被引:5,自引:0,他引:5  
本研究用采集的多用木工机床和冲击电钻发出的噪声对 5天、1 0天和 2 0天三个噪声干扰组的动物进行干扰 ,以研究非稳态噪声对动物行为及心脏组织自由基损伤的影响。结果发现 ,非稳态噪声可引起动物旷场反应中走格数减少 ,站立及洗脸次数增加 ,并可诱发心脏组织的自由基反应 ,导致心脏组织的损害。因此得出结论 :①非稳态噪声可以对动物行为产生影响 ,并随着噪声暴露时间的延长而增强 ;②非稳态噪声可以造成心脏组织的自由基损伤。这一现象提示自由基损伤是介导噪声对心脏功能影响的重要因素之一。  相似文献

ⅢA期非小细胞肺癌治疗方式存在争议,对于N1期患者,外科手术被广泛接受,对于N2期患者,国内外存在一定的分歧。对于N2期患者,外科手术治疗的效果主要取决于纵隔淋巴结转移情况,微灶转移和单站淋巴结转移患者,外科手术治疗效果比较满意,多站淋巴结转移患者外科手术治疗效果较差,而是需要做行根治性的放化疗。  相似文献

The relationship between spirituality and bereavement has been studied in a multitude of disciplines, yet there is a significant gap in the counseling literature on this topic. The authors explore how spirituality is often avoided in secular counseling settings, discuss adverse effects of unresolved grief on clients' functioning, and propose the concept that spirituality can be used to help clients through the bereavement process. Finally, the authors offer research and clinically based interventions that counselors, particularly those who do not identify as faith‐based, can use to incorporate spirituality into their work with bereaved clients.  相似文献

Abstract

In this paper I explore Plato’s reasons for his rejection of the so‐called standard analysis of knowledge as justified true belief. I argue that Plato held that knowledge is an infallible mental state in which (a) the knowable is present in the knower and (b) the knower is aware of this presence. Accordingly, knowledge (epistēmē) is non‐propositional. Since there are no infallible belief states, the standard analysis, which assumes that knowledge is a type of belief, cannot be correct. In addition, I argue that Plato held that belief (doxa) is only possible for the sort of being capable of knowledge. This is because self‐reflexivity is necessary for infallible knowledge and self‐reflexivity is only possible if the intellect is immaterial. This capacity for self‐reflexivity is also essential for belief, since beliefs are, paradigmatically, not dispositions but self‐reflexive mental states.  相似文献

In this paper the author describes her work with a woman who, in her mid 20s, sought analysis for her non‐vomiting binge eating disorder. The paper explores how two aspects of Jung's view of the psyche as healthily dissociable were used to think about the potential for change contained within the explosive, aggressive energies in this patient's bingeing. The resultant approach takes the patient's splitting defences, dissociations and self‐destructive behaviour as a point of access to her unconscious. Seen in this way, these behaviours contain the seeds of recovery and are the starting point for analysis rather than defences against it. The paper also brings a number of Jungian and post‐Jungian ideas into conversation with aspects of contemporary thinking about subjectivity, identity and the longing for excess developed by Leo Bersani and Judith Butler.  相似文献

This article examines pathologies in the creation of symbols and those pathologies' ensuing consequences. It relies mainly on the vertices provided by Bion and Meltzer. It studies the different forms in which these lapses occur in symbolic processes, where they may create vacuums in symbolic networks or give rise to 'lies', and even destroy or de-symbolize established symbols. Based on Bion's concept of the minus-contained (-contained), I propose that when a symbol is attacked, a particular mental structure with its own peculiar characteristics comes about. This structure not only creates a vacuum in that mental zone, it ends up damaging the entire symbolization process. This contribution aims to describe that structure from the metapsychological point of view - contained. I end by synthesizing the possible widening of what could be a Bionian negative grid.  相似文献
