Joint Beliefs in Conflictual Coordination Games

The traditional solution concept for noncooperative game theory is the Nash equilibrium, which contains an implicit assumption that players probability distributions satisfy t probabilistic independence. However, in games with more than two players, relaxing this assumption results in a more general equilibrium concept based on joint beliefs (Vanderschraaf, 1995). This article explores the implications of this joint-beliefs equilibrium concept for two kinds of conflictual coordination games: crisis bargaining and public goods provision. We find that, using updating consistent with Bayes rule, players beliefs converge to equilibria in joint beliefs which do not satisfy probabilistic independence. In addition, joint beliefs greatly expand the set of mixed equilibria. On the face of it, allowing for joint beliefs might be expected to increase the prospects for coordination. However, we show that if players use joint beliefs, which may be more likely as the number of players increases, then the prospects for coordination in these games declines vis-à-vis independent beliefs.     

Nontransitive preferences in decision theory

Intransitive preferences have been a topic of curiosity, study, and debate over the past 40 years. Many economists and decision theorists insist on transitivity as the cornerstone of rational choice, and even in behavioral decision theory intransitivities are often attributed to faulty experiments, random or sloppy choices, poor judgment, or unexamined biases. But others see intransitive preferences as potential truths of reasoned comparisons and propose representations of preferences that accommodate intransitivities. This article offers a partial survey of models for intransitive preferences in a variety of decisional contexts. These include economic consumer theory, multiattribute utility theory, game theory, preference between time streams, and decision making under risk and uncertainty. The survey is preceded by a discussion of issues that bear on the relevance and reasonableness of intransitivity.     

气候资本主义:低碳经济的政治学

我们很可能处在亲历气候资本主义出现的初级阶段。它是一种基于逐渐摆脱和远离化石燃料使用来持续经济发展的资本主义新形式,其中,脱碳被看作是一种缓和资本主义积累与抑制气候变化要求之间矛盾的机遇。但是,它依然是一种资本主义——通过市场、私有财产和工人阶级等要素组织起来,而且经济增长是其至高无上的律令。在未来几十年里,无论哪种具体版本的气候资本主义的出现,它实现脱碳的能力将取决于其导向低能源和低碳能源的投资的能力,同时还要处理好合法性的挑战,这些挑战不可避免地来自这种将全球金融作为管理碳排放手段的依赖。就全球气候变化管治的发展而言,无论是在《联合国气候变化框架公约》之下,还是最终超越了这一框架,成功的关键在于它是否能够创造一个有力的环境使全球经济转变为一种与强调气候变化相容的气候资本主义制度,或者,碳市场只是一种其取向与严肃应对气候危机的诸多努力不相容的经济制度中的孤立性存在。     

A conceptual framework for the study of work and mental health

Abstract

The key features which influence mental health both in jobs and unemployment are brought together within a single perspective. Three principal axes of affective well-being are identified as warranting investigation, and it is suggested that nine environmental features are of primary importance. The impact of these features on mental health is viewed as analogous to the influence of vitamins on physical health, with an explicit non-linearity in the relationship. This ‘vitamin model’ is extended to permit examination of individual differences (for example, in terms of baseline values and specific matching characteristics), and empirical evidence is summarized. It is concluded from previous research that job features do not interact synergistically in relation to employee well-being, although this possibility may not yet have been adequately tested. The framework is suggested to be adequately comprehensive, but, as is the case with other models, it requires development in respect of the specific mechanisms operating between environmental features and mental health.     

The Interacting-Reflecting Training Exercise: Addressing the Therapist’s Inner Conversation in Family Therapy Training

In recent years several authors have made a beginning in describing therapeutic conversations from a dialogical perspective. Training and supervision, however, have not yet been addressed from a dialogical perspective. In this article, an experiential training exercise is described that is focused on the basic dialogical skills of the trainee: respectful inquiry and constructive reflecting. Rather than teaching and instructing, this training exercise is aimed at staging a dialogue. The trainees are invited to take part in this dialogue, as they are encouraged to experiment with new positions and new ways of encountering others, and as their different voices tell of their experiences, of the things they have learned, and of the new perspectives that have opened up for them. Leaning on ideas about the therapist’s inner conversation (Rober, 1999, 2005b) and stressing the importance of polyphony, dialogism, and tolerance for uncertainty, the training exercise described in this article is consistent with a dialogical and postmodernist frame, as described by Seikkula and Olson (2003) .     

The Job Demands-Job Control Model and absence behaviour: results of a 3-year longitudinal study

Empirical results of earlier studies only marginally supported the relevance of Karasek's Job Demands-Job Control Model for absence behaviour. Since longitudinal studies with respect to these relations were largely lacking, a four-wave panel study was carried out using data from 1755 male employees of a technical maintenance firm in the public sector. Job demands, job control, physical working conditions, and the employee's age, education, and health were measured in one year and absenteeism in the same year and in the next 3 years. Data were analysed with linear regression and Poisson regression techniques. The Poisson regression technique was superior to the linear regression technique in explaining absence. Age, health and prior absence were the best predictors of later absence behaviour. With respect to the Job Demands-Job Control Model, the main findings of the study were (1) that job control was significantly associated with a low number of simultaneous and later absence days, and (2) that, contrary to expectations, job demands were also related to a low number of simultaneous and later absence days. These results hold when age, health, education, prior absence, and working conditions are controlled for. Job control and job demands did not predict later absence frequency. In the discussion it is suggested that a high level of job demands may not only be harmful for the well-being of employees but also work as 'a pressure to attend'.     

Affective and aesthetic dimensions of contemporary social movements in South West England

The paper examines contemporary social movement activity within South West England. It is argued that much social movement analysis has been too nation‐state orientated, that it has too readily framed diverse contemporary practices within a narrow, politically reductive and instrumentally rational frame. Increasingly, aesthetic and affective dimensions of everyday life must be examined if any coherent theoretical account of such activity is to be offered. Altering relations between states and their citizens in a global age and the emergence of an extended civil society are linked to a weakening of the capacity of nation states to manage identity formation. A series of excursuses link theoretical analysis of the expressive dimensions of the region's social movement activity, to these more extended global transformations.     

Squaring the welfare circle and government ideology: Greece and Spain in the 1990s

This article examines the "squaring the welfare circle" thesis and its usefulness to our understanding of welfare developments in Greece and Spain in the 1990s. The welfare state in both Greece and Spain was expanded considerably in the early 1980s by the newly elected socialist governments, only to hit the buffers of diminishing resources and rising demands in the late 1980s as well as the hostile neo-liberal welfare ideology. The process of welfare expansion was halted in the 1990s, labour market deregulation was encouraged and containment of welfare expenditure became the dominant aim of government policies. This article concentrates on the actual policies of governments in the 1990s rather than on the rhetoric of political parties. It concludes that governments of both the Left and the Right in both countries attempted to "square the welfare circle" mainly through reductions in the supply of welfare. This general conclusion is country-specific and may not apply to other countries involved in welfare restructuring. While recognizing the significance of institutional factors to welfare reform, the article concentrates on the outcomes of reforms rather than on the political process leading to them.
