Relative numbers of males and females in breeding groups may vary from expected values owing to a variety of factors. To determine how sex ratio might influence individual phenotypes in a captive population of dark-eyed juncos Junco hyemalis during the breeding season, we established three treatment groups: a male-biased (2:1), equal (1:1), and female-biased group (1:2). Within-group density (b...

Purpose: To evaluate the effect of a ‘social’ dose of alcohol on the central retinal sensitivity and fixation stability, measured with microperimetry using scanning laser ophthalmoscopy (SLO). Patients and methods: Eighteen subjects, nine males and nine females, were given alcohol in a ‘social’ dose, corresponding to 40 ml wine/70 kg/30 minutes. Alcohol level, visual acuity (VA), and contrast s...

We are investigating a paradigm of instability in coalition forming among countries, which indeed is intrinsic to any collection of individual groups or other social aggregations. Coalitions among countries are formed by the respective attraction or repulsion caused by the historical bond propensities between the countries, which produced an intricate circuit of bilateral bonds. Contradictory a...

Poletti and colleagues question whether the breadth of subjective and inter-subjective experience in psychosis can be reduced to problems with social agent representation. Their question is important, although we note our aim is not reductive and that we hope that a social agent representation approach is one of many possible phenomenological routes to a better neurocognitive understanding of p...

Many sub-Saharan African countries are confronted by the HIV/AIDS epidemic. This article reviews academic literature in the social sciences and health to discover why HIV/AIDS has become an epidemic in sub-Saharan Africa and not in other parts of the world. This was studied by examining the social determinants of diminishment of tradition and social cohesion in terms of political, social and ec...

This essay presents a reflection on the main implications of Complexity Theory for science in general, redefining and dispelling myths of traditional science, and Sociology in particular, suggesting a redefinition of Parsons’ classic concept of Social System, articulated around the property of self-maintenance of order rather than on its possible discontinuity and instability. It argues that Co...

This paper assesses the consequences of residential instability during the first five years of a child’s life for a host of school readiness outcomes. Using data from the Fragile Families and Child Wellbeing Study, we examine the relationship between multiple moves and children’s cognitive and behavioral readiness at age five. We further test this relationship for differences among poor, near p...
