The modular structure of physical theories

Any advanced theory of physics contains modules defined as essential components that are themselves theories with different domains of application. Different kinds of modules can be distinguished according to the way in which they fit in the symbolic and interpretive apparatus of a theory. The number and kind of the modules of a given theory vary as the theory evolves in time. The relative stability of modules and the variability of their insertion in other theories play a vital role in the application, comparison, construction, and communication of theories. Modularity conveys some global unity to physics through the sharing of modules by diverse theories. This alternative to rigid hierarchies and holistic totalities permits a dynamical, plastic, and symbiotic approach to physical theory.     

What Makes a Basic Structure Just?

In his multi-faceted attack on Rawls’s account of justice, G.A. Cohen has argued that the notion of basic structure is necessarily insensitive to the importance of informal social norms to social justice. The paper argues that the most plausible account of the basic structure is not blind to informal social norms in any meaningful sense. Whereas informal, non-legally coercive institutions are not part of the basic structure as such, their careful consideration is necessary for the assessment of whether the basic structure itself is indeed just. This claim is based on an account of what it means for normative principle to apply to institutions, which I expound in detail throughout the paper. Principles apply to institutions, I argue, not in that they restrain their conduct, but in that they indicate which social conditions they should bring about.

Immigration from the perspective of hosts and immigrants: Roles of psychological essentialism and social identity

Implicit person theory research can be conceptualized within the framework of psychological essentialism. Essentialist beliefs are associated with entity theories and both predict phenomena such as stereotyping. The present research extended previous work on the links between implicit theories and social identity processes, examining how essentialist beliefs are associated with social identification and processes related to prejudice and intergroup perception. After developing a new measure of essentialist beliefs in Study 1, Study 2 showed that these beliefs were associated with negative bias towards immigrants, particularly when participants were primed with an exclusive social identity. In Study 3, essentialist beliefs among immigrants moderated their adoption of Australian identity as a self-guide during acculturation. Essentialist beliefs therefore play a significant role in the psychology of social identity.

Action-dependent perceptual invariants: from ecological to sensorimotor approaches

Ecological and sensorimotor theories of perception build on the notion of action-dependent invariants as the basic structures underlying perceptual capacities. In this paper we contrast the assumptions these theories make on the nature of perceptual information modulated by action. By focusing on the question, how movement specifies perceptual information, we show that ecological and sensorimotor theories endorse substantially different views about the role of action in perception. In particular we argue that ecological invariants are characterized with reference to transformations produced in the sensory array by movement: such invariants are transformation-specific but do not imply motor-specificity. In contrast, sensorimotor theories assume that perceptual invariants are intrinsically tied to specific movements. We show that this difference leads to different empirical predictions and we submit that the distinction between motor equivalence and motor-specificity needs further clarification in order to provide a more constrained account of action/perception relations.

Consequences of Economic Inequality for the Social and Political Vitality of Society: A Social Identity Analysis

Economic inequality has been found to have pernicious effects, reducing mental and physical health, decreasing societal cohesion, and fueling support for nativist parties and illiberal autocratic leaders. We start this review with an outline of what social identity theorizing offers to the study of inequality. We then articulate four hypotheses that can be derived from the social identity approach: the fit hypothesis, the wealth-categorization hypothesis, the wealth-stereotype hypothesis, and the sociostructural hypothesis. We review the empirical literature that tests these hypotheses by exploring the effect of economic inequality, measured objectively by metrics such as the Gini coefficient as well as subjectively in terms of perceptions of economic inequality, on wealth categorization (of others and the self), the desire for more wealth and status, intergroup hostility, attitudes towards immigrants, prosocial behavior, stereotyping, the wish for a strong leader, the endorsement of conspiracy theories, and collective action intentions. As we will show, this research suggests that economic inequality may have even more far-reaching consequences than commonly believed. Indeed, investigating the effects of economic inequality on citizens' sociopolitical behaviors may be increasingly important in today's turbulent political and social landscape.     

Applying the principles and techniques of solution-focused therapy to career counselling

Career counselling aims to help clients become more effective agents in solving problems in their vocational aspects of life. To achieve this goal, theorists and practitioners are called upon to form useful helping approaches that can help clients in a more efficient and effective manner. This article proposes an alternative model toward this end by considering and adopting principles and techniques from the solution-focused therapy in career counselling practice. After a very brief introduction of the basic features of the solution-focused counselling, the paper reviews some key theoretical principles of the solution-focused therapy, and connects these principles to career counselling context. It then illustrates several solution-focused counselling techniques that are particularly applicable to career counselling intervention.
