The Rawlsian perspective on social policy pays particular attention to the least advantaged members of society, but how should “the least advantaged” be identified? The concept of deprivation dominance operationalizes in part the Rawlsian evaluation of the welfare of the least advantaged members of society, but a statistical procedure for testing deprivation dominance is needed. In this paper, ...

Five studies tested whether intergroup contact reduces negative outgroup attitudes through a process of ingroup distancing. Based on the deprovincialization hypothesis and Social Dominance Theory, we hypothesized that the indirect effect of cross-group friendship on outgroup attitudes via reduced ingroup identification is moderated by individuals' Social Dominance Orientation (SDO), and occurs ...

Segregation and stabilization of thalamocortical afferents to eye-specific patches, so-called "ocular dominance (OD) columns," in visual cortex are hypothesized to be based on activity-dependent competition for trophic factors such as brain-derived neurotrophic factor (BDNF) between afferents representing the two eyes during the critical period of postnatal development. To test this hypothesis ...

There has been a long-standing debate on the complex correlation between the development of human hand preference and brain lateralization. Handedness, used as a proxy for cerebral lateralization, is a topic of considerable importance because of its potential to reveal the mechanisms of the underlying pathophysiology of problems related to brain development or cognitive systems. Twin studies, w...

Phil Bryden was a seminal figure in the development of the field of cerebral lateralization in the last half of the twentieth century, and a founding editor of this journal. Here his founding co-editors reminisce about their friend and colleague, and reflect on his wide-ranging influence in the field and in their own careers.

A notable feature of U.S. social networks is their high degree of racial homogeneity, which is often attributed to racial homophily--the preference for associating with individuals of the same racial background. The authors unpack racial homogeneity using a theoretical framework that distinguishes between various tie formation mechanisms and their effects on the racial composition of networks, ...

PURPOSE Low-grade inflammation, measured by circulating levels of cytokines, is a pathogenic mechanism for several chronic diseases of aging. Identifying factors related to inflammation among African-American youths may yield insights into mechanisms underlying racial disparities in health. The purpose of the study was to determine whether (1) reported racial discrimination from ages 17-19 year...

     Improved drought-tolerant maize hybrids would significantly reduce water consumption and increase yield in arid environments. Our knowledge about genetic parameters is very essential before starting a successful breeding program. The present research was carried out throughout three successive years between 2013-15 to reveal the pattern of inheritance in yield, yield-components and related...

introduction: based on the previous studies, we know that the hemispheric lateralization defects, increase the probability of psychological disorders. we also know that dominant limb is controlled by dominant hemisphere and limb preference is used as an indicator for hemisphere dominance. in this study we attempted to explore the hemispheric dominance by the use of three limbs (hand, foot and e...
