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.  相似文献

Quasi-equational logic concerns with a completeness theorem, i. e. a list of general syntactical rules such that, being given a set of graded quasi-equations Q, the closure Cl Q = Qeq Fun Q can be derived from by the given rules. Those rules do exist, because our consideration could be embedded into the logic of first order language. But, we look for special (quasi-equational) rules. Suitable rules were already established for the (non-functorial) case of partial algebras in Definition 3.1.2 of [27], p. 108, and [28], p. 102. (For the case of total algebras, see [35].) So, one has to translate these rules to the (functorial) language of partial theories .Surprisingly enough, partial theories can be replaced up to isomorphisms by partial Dale monoids (cf. Section 3), which, in the total case are ordinary monoids.Special issue of Studia Logica: Algebraic Theory of Quasivarieties Presented by M. E. Adams, K. V. Adaricheva, W. Dziobiak, and A. V.

Philosophers of biology have long argued that Darwin's theory of evolution was qualitatively different from all earlier theories of evolution. Whereas Darwin's predecessors and contemporaries explained adaptation as the transformation of a species' "essence," Darwin explained adaptation as the selective propagation of randomly occurring mutations within a population. The present study explored the possibility of a parallel between early "transformational" theories of evolution and modern na?ve theories. Forty-two high school and college students and three evolutionary biologists were tested on their understanding of six evolutionary phenomena: variation, inheritance, adaptation, domestication, speciation, and extinction. As predicted, a plurality of participants demonstrated transformational reasoning inconsistent with natural selection. Correlational analyses revealed that participants who demonstrated transformational reasoning were as internally consistent as participants who demonstrated an understanding of natural selection, with the exception of one group of participants who appeared to have assimilated two heuristics--"survival of the fittest" and "acquired traits are not inherited"--into an otherwise transformational framework. These findings suggest that the widespread and early-developing tendency to essentialize biological kinds precludes students from conceptualizing species as populations of individuals differentially affected by the environment.  相似文献

Teleological-functional explanations account for objects by reference to their purpose. They are a fundamental aspect of adults' explanatory repertoire. They also play a significant role in children's reasoning although prior findings indicate that, in contrast to adults, young children broadly extend teleological explanation beyond artifacts (e.g. chairs) and biological properties (e.g. eyes) to the properties of non-living natural phenomena (e.g. clouds, rocks). The present study extends earlier work with American children to explore British children's application of teleological explanation. The motivation is that while Britain and America are, culturally, as close to a minimal pair as the global context affords, there are differences in the religiosity of the two nations such that British children might be less inclined to endorse purpose-based explanation. Results reveal that young British children also possess a promiscuous teleology although they differ in the kinds of purposes that they attribute. Additional findings include a replication of earlier effects using a modified task with young American children.  相似文献

Margaret Mohrmann, Paul Lauritzen, and Sumner Twiss raise questions about my account of basic interests, liberal theory, and the challenges of multiculturalism as developed in Children, Ethics, and Modern Medicine. Their questions point to foundational issues regarding the justification and limitation of parental authority to make decisions on behalf of children in medical and other contexts. One of the central questions in that regard is whether adults' decisions deserve to be respected, especially when they seem contrary to a child's or adolescent's basic interests. Questions about respect, in turn, focus attention on other's decisions about what seems good for families and children, decisions that may be paternalistic or utilitarian. Such decisions are further complicated by a child's or adolescent's budding autonomy and need for respect and recognition. Pediatric bioethics grounded in an account of a child's basic interests produces a theory of negative and positive rights for assessing adults' actions in relation to children, especially (but not only) when adults demand respect in their expressions of care.  相似文献

Summary  Whenever an adequate theory is found in science, we will still be left with two questions: why this theory rather than some other theory, and how should this theory be interpreted? I argue that these questions can be answered by a theory of system relations. The basic idea is that fundamental characteristics of systems, viz. those arising from the general systemic nature of those systems, cannot be comprehended with the aid of discipline-specific methods. The systems theory required should commence with an analysis of the qualitatively different relations possible between systems, because it is precisely the nature of those relations that determines the basic structures of systems. That the theory of the fundamental system relations and their ontological and epistemological implications is indeed able to provide the answers sought is demonstrated in theoretical physics and Plessner’s analysis of the basic structures of plant, animal and human being.  相似文献

人与情境交互作用理论认为,人一情境系统是一个整合、复杂和动态的整体,个体是其中一个积极和有目的的部分。该理论对情境在个体功能和发展中的作用、人一情境系统发挥自身功能的原则,以及人和情境子系统的结构和过程作了详尽的分析。这些理论主张对当前心理学的理论、方法和研究策略具有深远的启示意义,但也存在难以操作化的缺点。  相似文献
