Bridging the Gap between Theory and Policy

Two decades ago, Alexander George observed a growing gap between academic theorists and practitioners in the formulation of foreign policy. The significance of the gap has been debated, but trends in the academy, society, and government suggest it is likely to grow.     

Reflections on the deBroglie–Bohm Quantum Potential

The deBroglie–Bohm quantum potential is the potential energy function of the wave field. The quantum potential facilitates the transference of energy from wave field to particle and back again which accounts for energy conservation in isolated quantum systems. Factors affecting energy exchanges and the form of the quantum potential are discussed together with the related issues of the absence of a source term for the wave field and the lack of a classical back reaction.     

Getting Vygotskian about theory of mind: Mediation,dialogue, and the development of social understanding

The ideas of Vygotsky [Vygotsky, L. S. (1987). Thinking and speech. In The collected works of L. S. Vygotsky, (Vol. 1). New York: Plenum. (Original work published 1934.)] have been increasingly influential in accounting for social–environmental influences on the development of social understanding (SU). In the first part of this article, I examine how Vygotskian ideas have to date been recruited to explanations of the development of SU. Next, I present a model of SU development which draws on two implications of Vygotsky’s ideas: the importance of semiotic mediation for mental functioning, and the dialogic nature of the higher mental functions. I then consider the value of the proposed model in accounting for evidence from three areas of enquiry: the typical development of SU in infancy and early childhood, relations between individual differences in SU and social–environmental variables, and atypical development. The model is suggested to be particularly helpful in understanding the transition from intentional-agent to mental-agent understanding, and the role of language in SU. Remaining challenges include a need to specify further the cognitive processes underlying internalization, and to gather more extensive evidence on the roles of typical and atypical social experience in SU development.     

Self-objectification and Well-being: The Impact of Self-objectification on Women’s Overall Sense of Self-worth and Life Satisfaction

Research on objectification theory (Fredrickson and Roberts in Psychology of Women Quarterly 21:173–206, 1997) has demonstrated relations among self-objectification, body shame, and negative health outcomes. Less research has focused on the relation of self-objectification to indicators of well-being. We examined associations among self-objectification, body shame, and two indicators of well-being (i.e., self-esteem and satisfaction with life) in a path analytic model. We also tested explicitly whether body shame mediated the relation between self-objectification and self-esteem and whether self-esteem mediated the relation between body shame and life satisfaction. Female undergraduates (N = 227) from the United States completed questionnaires assessing the constructs of interest. Results indicated that the proposed model fit the data and that body shame and self-esteem mediated as predicted. Implications of these findings are discussed.     

The effect of comparative context upon stereotype content: children's judgments of ingroup behavior

This study addresses self-categorization theory's contention that stereotype content varies as a function of the comparative context within which a given group is considered. A sample of 5-, 7- and 10-year-old children (n = 192) made judgments about gender ingroup behavior in one of two comparative contexts: either adults of the same sex as self or children of the opposite sex. Specifically, judgments were either of the perceived stereotypicality or central tendency of 12 types of behavior. Both types of judgment were found to differ as a function of comparative context in ways predicted by self-categorization theory. However, contrary to prediction, there was no effect of age on the extent of stereotype variability.     

Towards a “Sophisticated” Model of Belief Dynamics. Part I: The General Framework

It is well-known that classical models of belief are not realistic representations of human doxastic capacity; equally, models of actions involving beliefs, such as decisions based on beliefs, or changes of beliefs, suffer from a similar inaccuracies. In this paper, a general framework is presented which permits a more realistic modelling both of instantaneous states of belief, and of the operations involving them. This framework is motivated by some of the inadequacies of existing models, which it overcomes, whilst retaining technical rigour in so far as it relies on known, natural logical and mathematical notions. The companion paper (Towards a “sophisticated” model of belief dynamics. Part II) contains an application of this framework to the particular case of belief revision.

Elimination problems in logic: a brief history

A common aim of elimination problems for languages of logic is to express the entire content of a set of formulas of the language, or a certain part of it, in a way that is more elementary or more informative. We want to bring out that as the languages for logic grew in expressive power and, at the same time, our knowledge of their expressive limitations also grew, elimination problems in logic underwent some change. For languages other than that for monadic second-order logic, there remain important open problems.     

Literature,Ethics, and Richard Rorty’s Pragmatist Theory of Interpretation

This article considers the validity and strength of Richard Rorty’s pragmatist theory of interpretation in the light of two ethical issues related to literature and interpretation. Rorty’s theory is rejected on two grounds. First, it is argued that his unrestrained account of interpretation is incompatible with the distinctive moral concerns that have been seen to restrict the scope and nature of valid approaches to artworks. The second part of the paper claims that there is no indispensable relationship between supporting Rorty’s pragmatist theory of interpretation and the important place that is attached to literature in the liberal society outlined by him. A reading of Donald Davidson’s texts on literary language and interpretation implies that an intentionalist theory of interpretation can accommodate those features that Rorty values in literature as well.

The darker side of accommodating others: Examining the interpersonal structure of maladaptive constructs

To better understand the greater prevalence of depression among women, compared to men, we explored the darker side of accommodating others by examining where maladaptive relational constructs fit within a general structural framework provided by the interpersonal circumplex and 5-factor model of personality. Participants were four samples of undergraduate students (Ns = 302–2070) who completed questionnaires. Results indicated two clusters of maladaptive items: Submission with Connection and Submission without Connection. In general, the most maladaptive relational constructs were concentrated in the first cluster and were located in the low agency, low communion region of the interpersonal circumplex.
