Dynamic decision making: a comparison of approaches

This paper is concerned with a specific type of problem, namely dynamic decisions, for which most techniques fail to provide adequate solutions. Here, we present two of the most promising optimization techniques, partially observable Markov decision processes (POMDP) and dynamic decision networks (DDN), while arguing which is the most suitable for this problem domain.

Optimal trade-offs of multiple factors in transfer pricing problems

Transfer pricing problems have been extensively researched by a number of scholars. It is well recognized that transfer pricing problems have a multiple-criteria (objectives) feature and can be formulated as a model of multiple-criteria linear programming. However, few methods have the capability of dealing with all possible optimal trade-offs of multiple criteria in optimal solutions of the models. In this paper a linear multiple-factor model is developed to provide managers with a more systematic and comprehensive scenario of all possible optimal transfer prices depending on both multiple criteria and multiple constraint levels. The trade-offs of all possible optimal transfer prices can be used as a basis for managers of a corporation to make a high-quality decision in selecting their transfer pricing systems for business competition. © 1998 John Wiley & Sons, Ltd.     

A Comparison of the 1988 and 1994 Diagnostic Criteria for Chronic Fatigue Syndrome

Chronic Fatigue Syndrome (CFS) is an illness that involves severe, prolonged fatigue as well as neurological, immunological, and endocrinological system pathology. Because the pathogenesis of CFS has yet to be determined, case definitions have relied on clinical observation in classifying signs and symptoms for diagnosis. In an attempt to address various criticisms and inconsistencies in diagnostic criteria, there have been several revisions of the CFS case definition. The current investigation examined the differences between 1988 and 1994 definitions as well as participants who had a psychiatric explanation for their fatigue. Dependent measures included psychiatric comorbidity, symptom frequency, and functional impairment. The 1988 criteria, compared to the 1994 criteria, appeared to select a group of participants with more symptomatology and functional impairment, but these groups did not significantly differ in psychiatric comorbidity. Implications of these findings are discussed.     

Consumers' product evaluation: a study of the primary evaluative criteria in the precious jewellery market in the UK

It is normally argued that consumers make their purchase decisions on the basis of their evaluation of, and knowledge about, the product attributes. This paper reports findings from a research study, which was conducted to determine the nature and type of evaluative criteria used by an individual while purchasing a piece of precious jewellery. In doing so, the study looked into the significance of product category knowledge, brand familiarity and brand consciousness in product evaluation. A questionnaire was sent to 500 consumers of precious jewellery in five major cities of the UK. Results indicate that, in general, subjective attributes are more important for people buying precious jewellery than the objective attributes. The significance of specific attributes during product evaluation could vary according to one's level of product category knowledge, brand familiarity and brand consciousness. The paper discusses implications for the marketers. Copyright © 2001 Henry Stewart Publications.     

A Bibliographic Survey of the Activities and International Nature of Multiple Criteria Decision Making

One of the fascinating things about multiple criteria decision making (MCDM) is the degree to which the contributions that have built the field have come from all over the world. In this paper the international nature of the authorships of the 1216 refereed journal articles published on MCDM between 1987 and 1992, and the journals in which they have appeared, is examined. Also, an analysis of the 217 books and 31 journal special issues that have been published on MCDM, and 143 conferences that have been held on MCDM since the inception of the field, is similarly conducted. The paper concludes with a conference organizer, author and special issue guest editor index.     

Anxiety sensitivity and intolerance of uncertainty: requisites of the fundamental fears?

Fears related to anxiety sensitivity (AS)-illness/injury sensitivity, fear of negative evaluation, and fear of pain-may have important theoretical associations with intolerance of uncertainty (IU). In separate investigations, AS and IU have been independently related to the same anxiety-related psychopathology. AS and IU seem to share a basis in fearing unknown, potentially harmful consequences; however, their inter-relationship remains uncertain. IU regarding a specific stimulus, a physical sensation for example, may result in a variety of interpretations and responses, including the catastrophic appraisals that characterize AS. The association between AS and IU was examined in a sample of 293 undergraduates. Results of confirmatory factor and correlation analyses suggest the two constructs are related, but nonetheless independent. It appears that IU may be a required component of catastrophic misappraisals while being an important construct related to fear and anxiety in its own right. Future research directions and potential applications are discussed.     

The coming changes in psychoanalytic education: Part II

This paper is the second part of a general analysis of problems in contemporary psychoanalytic education. Having proposed changes in the training analysis and supervisory systems in Part I, here the author focuses on concrete proposals regarding changes in the curriculum, seminars and classroom teaching; the governance of psychoanalytic institutes, relationship of institutes with their respective psychoanalytic society and the role of the university in the development of science and research; the admission, progression, and graduating processes; certifi cation and accreditation.     

Variability in response criteria affects estimates of conscious identification and unconscious semantic priming

Three experiments examined the role of response criteria in a masked semantic priming paradigm using an exclusion task. Experiment 1 used on-line prime-report (“report the prime if you saw it”) and exclusion instructions in which participants were told to avoid completing a word stem (e.g. mo—) with a word related to a prime (e.g. cash) flashed for 0, 38 or 212 ms. Semantic priming (i.e. exclusion failure) was significant in the items analysis, but was moderated by peoples’ ability to report the prime in the participant analysis. Prime-report thresholds in Experiment 2 were made more liberal by instructing participants to guess on every trial. Prime-report increased from Experiment 1 as exclusion failures were eliminated. Experiment 3 clarified the relationship between awareness and prime identification using an on-line measure of confidence and different liberal prime report instructions. The current findings suggest that the ability to act upon (via exclusion performance) and report information in a masked prime is determined by a variable response criterion, which can be manipulated as an independent variable.     

多发性硬化诊疗指南评析

我国无统一的多发性硬化（MS）诊断标准,MS的诊断依据Poser标准和McDonald标准。McDonald标准是建立在Poser标准基础上,但更注意利用包括MRI在内的相关实验室检查来证明多发性硬化在时间和空间上的多发性,有利于MS的早期诊断及治疗。对于没有MRI仪器的地方或不能承担MRI检查费用者,可用Poser标准进行诊断,但要注意行视觉诱发电位检查及脑脊液寡克隆IgG区带测定。
