Criteria are the central focus of multi‐criteria decision analysis. Many authors have suggested using our values (or preferences) to define the criteria we use to evaluate alternatives. Value‐focused thinking (VFT) is an important philosophy that advocates a more fundamental view of values in our decision making in our private and professional lives. VFT proponents advocate starting first with our values and then using our values to create decision opportunities, evaluate alternatives and finally develop improved alternatives. It has been 20 years since VFT was first introduced by Ralph Keeney. This paper surveys the VFT literature to provide a comprehensive summary of the significant applications, describe the main research developments and identify areas for future research. We review the scope and magnitude of VFT applications and the key developments in theory since VFT was introduced in 1992 and found 89 papers written in 29 journals from 1992 to 2010. We develop about 20 research questions that include the type of article (application, theory, case study, etc.), the size of the decision space (which, when given, ranged from $200K to billions of dollars), the contribution documented in the article (application benefits) and the research contributions (categorized by preferences, uncertainties and alternatives). After summarizing the answers to these questions, we conclude the paper with suggestions for improving VFT applications and potential future research. We found a large number of significant VFT applications and several useful research contributions. We also found an increasing number of VFT papers written by international authors.

Solving complex decision problems is a demanding task; it requires determining and evaluating the consequences of decision alternatives. To this end, uncertain factors that can only partly be influenced by the decision makers, and their interdependencies need to be considered. Scenarios focus on this part of the decision problem; they enable a systematic exploration of a multitude of possible future developments that are relevant for the decision including external events and decisions made. Scenarios are particularly useful when the problem is pervaded by severe uncertainties that cannot be quantified. For the evaluation of alternatives, multiple objectives and the potentially diverging preferences of the involved actors need to be respected. Multi‐criteria decision analysis aims at structuring the problem, evaluating the alternatives and supporting decision makers pursuing multiple goals. We propose an approach integrating scenarios and multi‐criteria decision analysis that focuses on the robustness of alternatives in complex, dynamic, uncertain and time‐bound situations. In this integrated framework, the scenarios provide the basis for evaluating a set of alternatives. Ideally, the set of scenarios considered captures all possible future developments. To appropriately explore this set, formal or analytical approaches to scenario construction generate a large number of scenarios. This challenges the decision makers' information‐processing capacity. To support them in managing the richness of information, a two‐fold approach that uses selection and aggregation is presented. By using a selection method, the scenarios that are deemed most relevant are identified, and their evaluations are presented in detail to decision makers. This approach is complemented by an aggregation of scenario evaluations on the basis of the decision makers' preferences. We present two approaches to facilitate the preference elicitation process.

Abstract

The main point of this paper is that a client's suitability for brief or time-limited therapy is determined by various factors, including context. There is still agreement on the validity of Malan's selection criteria, which included ‘mild illness, recent onset, high motivation and response to trial interpretation’, yet many additional issues have since emerged and need to be considered. For instance, the counsellor's suitability, training and work experience, the counsellor's assessment skills and ability to establish a dynamic focus, the clients' capacity for self-reflection, their ego strength and their response to a trial therapy in the first session. Then there is the importance of the various contexts in which nowadays much brief counselling is offered free to clients, whether in education, at the workplace, in primary healthcare settings or by charitable organizations. This means that issues of money and markets have come to the fore and an initial differential assessment needs to be carried out in order to decide which method or model of therapy is best for the client. Matching the counsellor's personality to the needs and to the pathology of the client, and matching the treatment to the client's developmental stage or life stage crises are other aspects of the work, which determine the issue of suitability. In the end as always there is much that remains unknown about what works for whom and how the client's decision to take up help is made.  相似文献

Professional visual searches, such as those conducted by airport security personnel, often demand highly accurate performance. As many factors can hinder accuracy, it is critical to understand the potential influences. Here, we examined how explicit decision‐making criteria might affect multiple‐target search performance. Non‐professional searchers (college undergraduates) and professional searchers (airport security officers) classified trials as ‘safe’ or ‘dangerous’, in one of two conditions. Those in the ‘one = dangerous’ condition classified trials as dangerous if they found one or two targets, and those in the ‘one = safe’ condition only classified trials as dangerous if they found two targets. The data suggest an important role of context that may be mediated by experience; non‐professional searchers were more likely to miss a second target in the one = dangerous condition (i.e., when finding a second found target did not change the classification), whereas professional searchers were more likely to miss a second in the one = safe condition.  相似文献

This article substantiates the thesis that the outlines of the future and present can be made visible and comprehensible by applying a new methodology for cognition of regularities in the human community development. This methodology made it possible to define that there have been and are only two paradigms of the human system development in the entire multicentury course of the human community development. Cycles, crises, chaos, and all negative phenomena are nothing else but natural products of the second, indirect paradigm of development. The new model of life organization at each local level is at the same time the former, first development paradigm, based on the direct interconnection between production and consumption of specific human beings, but raised onto the new high-tech level. Practical realization of this model is the only feasible precondition for the transition to sustainable and crisis-free development.  相似文献

Disturbing emotions that act as bodily cryptograms waiting to be deciphered are currently understood as intra-psychic trauma. The author briefly discusses Fordham's concepts of deintegration and primitive identity, as well as early patterns of mother-infant attunement to describe how the empathic capacity of the analyst is dramatically challenged in helping patients to give birth to unbearable emotions that remain an undifferentiated entity. Referring to Ogden's understanding of the mechanism of projective identification, the author will explore how unconscious mental processes in the analyst and the patient can work at re-activating failures in the deintegrative process. Clinical material is presented to show how unconscious psychic events that affect the patient but cannot be known consciously can be born into mind by the analytic couple.  相似文献

在质性研究中,资料饱和通常被用以评估研究资料的充足性。但在研究实践中,资料饱和却存在概念模糊及操作性问题。作为某项质性研究所抽取的样本量已满足研究需要的标志,按照在研究过程中判定时点的先后顺序,资料饱和可划分为数据饱和、编码或主题饱和、意义饱和及理论饱和4种主要形式。4种形式的资料饱和各有其特定的内涵、评估方式和判定标准。研究认为,达到资料饱和的样本量标准不应统一设定,其检验需嵌入具体的研究过程;资料饱和存在逻辑上的不确定性,适度追加抽样有助于进一步确认;资料饱和作为考察研究质量的一项重要指标,并不适用于所有质性研究。  相似文献

We introduce a bipolarly extended veto principle—a positive, as well as negative, large performance differences polarization—which allows us to extend the definition of the classical outranking relation in such a way that the identity between its asymmetric part and its codual relation is preserved.
