This welcomes Equality: From Theory to Action as an important contribution both to linking egalitarian political philosophy to public policy and as a book which helps
communicate a wealth of philosophical ideas in an accessible way to a wide public. On the critical side, it argues that the
authors understate some tensions between egalitarianism and pluralism, and that the book’s discussion of egalitarian economic
institutions is quite narrow in scope. As a complement and development of this latter discussion, the paper discusses some
policy proposals to address inequality of wealth. 相似文献

Socioeconomic status (SES) is associated with childhood cognitive achievement. In previous research we found that this association shows neural specificity; specifically we found that groups of low and middle SES children differed disproportionately in perisylvian/language and prefrontal/executive abilities relative to other neurocognitive abilities. Here we address several new questions: To what extent does this disparity between groups reflect a gradient of SES‐related individual differences in neurocognitive development, as opposed to a more categorical difference? What other neurocognitive systems differ across individuals as a function of SES? Does linguistic ability mediate SES differences in other systems? And how do specific prefrontal/executive subsystems vary with SES? One hundred and fifty healthy, socioeconomically diverse first‐graders were administered tasks tapping language, visuospatial skills, memory, working memory, cognitive control, and reward processing. SES explained over 30% of the variance in language, and a smaller but highly significant portion of the variance in most other systems. Statistically mediating factors and possible interventional approaches are discussed. 相似文献

Latencies (RT) and eye movement measures were used to examine the effects of age and contrast on the distractor-ratio effect (DRE) in visual search. Younger and older adults performed a contrast x orientation conjunction search task where the ratios of white to black distractors and luminance contrast levels were varied. The distractor-ratio manipulation had similar effects for older and younger adults on both RT and the number of fixations required to find the target. Both measures were largely independent of distractor ratio on target-present trials, while both RTs and the fixation number increased with the number of items sharing the target's contrast polarity on target-absent trials. A more detailed analysis of eye movements suggested that younger adults were a bit more adept at attending to the smaller set of distractors, which presumably facilitated both overt and covert search. Generalized slowing can account for the age differences in RT, but the fixation number data speak to another mechanism, perhaps increased cautiousness on the part of the elderly when signal strength is low. 相似文献

Residents (N = 142) of a southeastern, upscale retirement community completed measures of wellness, perceived stress, and mattering. Participants scored higher than did a group of adults under age 60 on 4 of 5 second‐order wellness factors and Total Wellness, with medium to large effect sizes. Implications for counselors are discussed. 相似文献

People with scleroderma often experience disfiguring appearance-related changes in socially visible and interpersonally salient areas. Although disfigurement can lead to body image dissatisfaction, this phenomenon has not been well investigated due to the lack of a disfigurement-specific measure. The Satisfaction With Appearance (SWAP) scale, previously developed in burn survivors, was adapted and administered to 254 participants with scleroderma to evaluate its psychometric integrity and its validity for use in a different medical population that experiences changes in appearance. Principal component analysis revealed two factors – Subjective Dissatisfaction and Perceived Social Impact – rather than the four found in burn victims. Excellent estimates of internal consistency and temporal stability and strong evidence for the reliability of the two-factor solution were found. The resulting factor structure in a scleroderma population suggests that differing medical conditions may create alternate constellations of BID, reflects the need for body image researchers to assess psychometrics across medical populations and may have clinical implications for BID interventions. 相似文献

ABSTRACT— The debate surrounding the use of subjective measures of well-being for policy purposes has intensified in recent years. Many social scientists are arguing that the time is right for policymakers to extend their traditional focus on material well-being and economic development to include the impact policies have on how people think and feel about their lives. However, policymakers may have many legitimate goals beyond making people happy. In this article, we begin by presenting three archetypal accounts of well-being that policymakers could use to guide policy (mental-state, objective-list, and desire-fulfillment accounts) and discussing some of the normative and methodological limitations of each. We discuss how a subjective (mental-state) approach could be used to aid the achievement of objective-list and desire-fulfillment policy goals. We then consider ways in which a subjective approach may benefit policymakers in its own right, such as by aiding the valuation of hard-to-quantify costs and benefits, providing a standard unit of measurement for comparisons of well-being across domains, and helping to set policy defaults. We conclude with a discussion of some of the remaining measurement issues and general policy implications. 相似文献

Despite experiments being increasingly conducted over the Internet, few studies have tested whether such experiments yield data equivalent to traditional methods' data. In the current study, data obtained via a traditional sampling method of undergraduate psychology students completing a paper‐and‐pencil survey (N = 107) were compared with data obtained from an Internet‐administered survey to a sample of self‐selected Internet‐users (N = 94). The data examined were from a previous study that had examined the persuasiveness of health‐related messages. To the extent that Internet data would be based on a sample at least as representative as data derived from a traditional student sample, it was expected that the two methodologies would yield equivalent data. Using formal tests of equivalence on persuasion outcomes, hypotheses of equivalence were generally supported. Additionally, the Internet sample was more diverse demographically than the student sample, identifying Internet samples as a valid alternative for future experimental research. 相似文献

Breaking the Fourth Wall and Sex Role Stereotypes: An Examination of the 2006–2007 Prime-Time Season
Characters break the fourth wall on television when they speak directly to the camera. Using a stratified random sample of one episode of every situation comedy, drama, and reality program airing on the five broadcast networks in the United States (N?=?113) during the 2006–2007 prime-time season, we found that, overall, male characters broke the fourth wall more frequently than females. However, when a program employed at least one woman in a powerful behind-the-scenes position, female characters broke the fourth wall more than males. Also, male characters breaking the fourth wall were more likely to make personal comments about themselves and others, whereas female characters talked about competitive strategy and competition. 相似文献
