Recent comparative studies across sex-changing animals have found that the relative size and age at sex change are strikingly invariant. In particular, 91%–97% of the variation in size at sex change across species can be explained by the simple rule that individuals change sex when they reach 72% of their...
Developmental bisphenol A (BPA) exposure is associated with adverse behavioral
effects, although underlying modes of action remain unclear. Because BPA is a
suspected xenoestrogen, the objective was to identify sex-based changes in adult
zebrafish social behavior developmentally exposed to BPA (0.0, 0.1 or 1 μM) or one of
two control...
Consistent with its charge under Oregon House Bill 3543, the Oregon Climate Change Research Institute (OCCRI) conducts a biennial assessment of the state of climate change science, including biological, physical, and social science, as it relates to Oregon and the likely effects of climate change on Oregon. This sixth Oregon...
Rapid change-of-direction tasks have been associated with non-contact anterior cruciate ligament (ACL) injuries and females are more likely to suffer this injury compared to males. The purpose of this investigation was to evaluate the biomechanical behavior of running and three rapid change-of-direction tasks and determine whether sex differences exist across...
National statistics indicate substantially higher rates of divorce
in doctoral student households where the female, rather than the male, is
the degree candidate. This research was designed to examine the married
female's experiences and to identify factors which possibly contribute
to the differential divorce statistics for males and females.
The...
This study examined the relative contribution of parental warmth,
non-authoritarianism, and approval of sex-typed behavior to children's
sex role knowledge and preference. Subjects were 45 married
couples, and their 25 male and 20 female preschool children. Parental
attitudes toward child-rearing and sex role behavior were assessed
with the Parent Attitude...
The present study compared the sex role learning of preschool
girls from families with "traditional" and "nontraditional" (egalitarian)
attitudes toward women's roles on measures of sex role knowledge and
preference. Forty-eight four and five year old girls from intact,
middle class families served as subjects. Their parents' attitudes
toward women's...
Purpose of the Study
The purpose of this study was to determine the effectiveness of
three methods of changing vocational educators' sex-role perceptions
of themselves and their sex-role perceptions of males and females to
a more androgynous state. The hypotheses tested were: (1) there
is no difference in sex -role...
The purpose of this investigation was to determine whether sex-role
identification differences among college students were related to place
of residence, and if so, whether certain factors affect these
differences. Six hypotheses were developed. The study sought to
ascertain if sex-role identification is related to certain dimensions of
peer association...
