Socialization within day care: A brief review

Studies examining the effects of day care are reviewed. Little evidence was found indicating a negative impact on child development. A number of weaknesses in the day care literature were pointed out, including problems of ecological validity and failure to examine for differential effects. Suggestions for future research are made, among them a “natural history” of day care and studies of children who have experienced trauma.     

Quantitative chromatographic profiling of odours associated with dominance in male laboratory mice

Triads of male NMRI mice were housed together and dominance hierarchies allowed to form. At age 19 weeks the mice were ranked on the basis of wins in spontaneous aggressive encounters, and whole-body volatiles were sampled by the dynamic solvent effect and quantitatively analysed by capillary gas chromatography. At age 26 weeks the mice were again ranked on the basis of wins in aggressive encounters, number of aggressive encounters initiated, and scent marking patterns, and whole-body volatiles were sampled and analysed. Chromatographic odour profile ranks agreed perfectly with aggressive initiator ranks and poorly with encounter winner ranks. Eight components of the whole-body odour were identified by gas chromatography-mass spectrometry; two of these are known semiochemicals. The results demonstrate that murine semiochemicals are accessible to quantitative analysis at the level of the individual.     

Parents’ Beliefs about High School Students’ Spatial Abilities: Gender Differences and Associations with Parent Encouragement to Pursue a STEM Career and Students’ STEM Career Intentions

In the present study, we investigated whether parents’ beliefs about their high school aged adolescents’ spatial abilities (i.e., spatial visualization, mental manipulation, and navigation abilities) differed based on their child’s gender. We also examined whether these beliefs related to parents’ encouragement of their child to pursue a Science, Technology, Engineering, or Mathematics (STEM) career as well as students’ actual STEM major and career intentions. Data were collected from 117 pairs of U.S. high school students and one of their parents. We found that parents of young men thought their child had higher mental manipulation and navigation abilities than did parents of young women, even after statistically controlling for adolescents’ actual spatial abilities. Parents who perceived that their child had higher mental manipulation ability were more likely to encourage their child to pursue a STEM career, and those students were more likely to report that they intended to pursue a STEM career. These findings suggest that parents’ beliefs about how good their child is at spatial tasks may be based more strongly on gender stereotypes than on their child’s actual spatial abilities. Helping to make parents aware of these beliefs could be a potential lever of intervention to increase women’s participation in STEM careers.

Why not to be a ‘Thomist’: A Critique of the Bañezian Reconciliation of Divine Foreknowledge and Human Freedom

Thomas Osborne has asserted that ‘No one has developed an argument against premotion that works if the distinctions made by the Thomists are granted.' This article attempts to form just such an argument. Specifically, it argues that the Thomistic system – even with the distinctions it relies on having been granted – cannot account for human freedom, at least not in a sense sufficiently strong to sustain human guilt for sin. Further, it argues that the Thomists, by their own clear though tacit admission, acknowledge this insufficiency.
