Preface The hypothesis of this paper is that the differences between Negroes and whites in the incidence of family disorganization are a function of race as a summary statement of their differential social-ecological positions. Using the 1/1000 Census tape for 1960, multiple regressions were run for various indicators of family disorganization on race and dimensions of social-ecological positio...

In their paper in this issue, Grusky and Charles (1998) make a number of dubious claims about the measurement and interpretation of sex segregation. First, they incorrectly claim that only log-odds measures yield margin-free measures of segregation. Second, the estimation and testing of a limited class of log-linear models does not provide an independent test of the appropriateness of a log-odd...

This paper outlines a perspective on the future of AI, discussing directions for machines models human-like intelligence. We explain how developmental and evolutionary theories human cognition should further inform artificial emphasize role ecological niches in sculpting intelligent behavior, particular that intelligence was fundamentally shaped to adapt constantly changing socio-cultural envir...

this study presents the electric behavior of sandwich devices based on porous silicon (ps) thin films with au/ps/si/cu structure when the material’s surface is exposed to different gases. ps thin films were fabricated by the electrochemical anodization method of si–c (100) substrates with resistivity 1.4-2.6 ωcm. samples were anodized in a solution of hf (48%), c2h5oh (99.98%) and distilled wat...

Shifting the focus from fear, guilt, and indignation related to deteriorating environmental quality, the authors hypothesized that people who see greater potential for restorative experiences in natural environments also do more to protect them by behaving ecologically, as with recycling or reduced driving. University students (N = 488) rated a familiar freshwater marsh in terms of being away, ...
