Testosterone during pregnancy and gender role behavior of preschool children: a longitudinal,population study 总被引:3,自引:0,他引:3
Hines M Golombok S Rust J Johnston KJ Golding J;Avon Longitudinal Study of Parents Children Study Team 《Child development》2002,73(6):1678-1687
Levels of testosterone (T) and sex hormone-binding globulin (SHBG) were measured in blood samples from pregnant women and related to gender role behavior in 342 male and 337 female offspring at the age of 3.5 years. Gender role behavior was assessed using the Pre-School Activities Inventory, a standardized measure on which a parent indicates the child's involvement with sex-typical toys, games, and activities. Levels of T, but not SHBG, related linearly to gender role behavior in preschool girls. Neither hormone related to gender role behavior in boys. Other factors, including the presence of older brothers or sisters in the home, parental adherence to traditional sex roles, the presence of a male partner in the home, and maternal education, did not relate to gender role behavior in this sample and did not account for the relation observed between T and behavior. Although other, unmeasured factors may explain the relation, the results suggest that normal variability in T levels prenatally may contribute to the development of individual differences in the gender role behavior of preschool girls. 相似文献

Technology’s rapid evolution applies constant pressure to educational organizations, suggesting a need to continually re-envision schools for the digital age. Yet educators often struggle to understand the growing chasm between students’ out-of-school and in-school technology lives. This gap is particularly noticeable during the middle grades years, when home technology use increases dramatically. The purpose of this research was to examine the experiences of teachers and students engaged in collaborative action research for middle school improvement in technology-rich settings. We begin by outlining our theoretical framework, emphasizing Fletcher’s Ladder of Student Involvement. We then describe our case-study design and methods. Findings are organized by action research components and a discussion of key themes follows. Finally, we consider the implications of this study for action research as a means of student involvement and teacher learning. 相似文献

The importance of success expectancy is discussed, followed by a review of the extensive but fragmented literature demonstrating that females frequently have a lower success expectancy than males in achievement contexts, despite having a similar performance. These varied findings are synthesized and cast into a framework asserting that success expectancy emerges from three major factors: (1) the meaning given to self and the achievement situation; (2) the familiarity that one has with the task; and (3) sex-stereotypic personality disposition. This framework is then tested for 342 college students. The results show that both meaning and familiarity significantly explain success expectancy, and that familiarity also significantly explains test performance. There is no evidence, however, for a sex-related personality disposition for lower success expectancy. The discussion focuses on the need to move beyond sex differences and focus on how meaning and familiarity can impact the success expectancy of all college students. 相似文献

Kember's linear‐process model of drop‐out from distance education (described in detail in Distance Education 10, 2, 196‐211) has been adapted and used as the basis for a series of interviews with students studying externally at Charles Sturt University‐Riverina. Although the sample is small, many issues are raised that arc relevant for distance educators. It is concluded Kember's model provides a useful theoretical underpinning for examining not only reasons for student withdrawal but also why they continue their studies. 相似文献

Power differences are observed in children's early relationships, yet little is known about how children conceptualize social power. Study 1 recruited adults (n = 35) to assess the validity of a series of vignettes to measure five dimensions of social power. Using these vignettes, Study 2 (149 three‐ to nine‐year‐olds, 42 adults) and Study 3 (86 three‐ to nine‐year‐olds, 22 adults) showed that children visiting a science museum at a middle class university town are sensitive to several dimensions of social power from a young age; however, an adult‐like breadth of power concepts does not develop until 7–9 years. Children understand social power whether the powerful character is malevolent or benevolent, though malevolent power is easier to detect for children and adults. 相似文献

AbstractWhen Piketty’s book Capital in the Twenty-first Century was released in 2014, it became an overnight success. Piketty focused on the concentration of wealth in a tiny social elite, and showed that their wealth had increased following the financial crisis in 2008. Yet the value of Piketty’s book offers something more than this for social scientists concerned with social inequalities. His work on a large data-set of long-run income and wealth statistics illustrates that the assumptions and models which have guided the work of neoclassical economists are flawed, but that societal arrangements matter. Yet despite this insight, Piketty’s solution to the problem of inequality is to argue that ‘… the best way to reduce inequalities with respect to labor … is to invest in education’. In this article I argue that there are major problems with this proposed solution and outline three lacunae that need to be addressed. 相似文献

Families Created by the New Reproductive Technologies: Quality of Parenting and Social and Emotional Development of the Children 总被引:14,自引:0,他引:14
The creation of families by means of the new reproductive technologies has raised important questions about the psychological consequences for children, particularly where gamete donation has been used in the child's conception. Findings are presented of a study of family relationships and the social and emotional development of children in families created as a result of the 2 most widely used reproductive technologies, in vitro fertilization (IVF) and donor insemination (DI), in comparison with control groups of families with a naturally conceived child and adoptive families. The quality of parenting was assessed using a standardized interview with the mother, and mothers and fathers completed questionnaire measures of stress associated with parenting, marital satisfaction, and emotional state. Data on children's psychiatric state were also obtained by standardized interview with the mother, and by questionnaires completed by the mothers and the children's teachers. The children were administered the Separation Anxiety Test, the Family Relations Test, and the Pictorial Scale of Perceived Competence and Social Acceptance. The results showed that the quality of parenting in families with a child conceived by assisted conception is superior to that shown by families with a naturally conceived child. No group differences were found for any of the measures of children's emotions, behavior, or relationships with parents. The findings are discussed in terms of their implications for understanding the role of genetic ties in family functioning and child development. 相似文献

A group of 110 LD college students were compared to a random stratified sample (RSS) of 153 peers attending the same moderately
selective college between 1980 and 1988. The LD students received comprehensive, highly coordinated support services for at
least one semester. The groups were matched on gender, college experience, semester, and year of entry to the college. The
LD and RSS groups were compared on high school preparation and performance, ACT and college performance, and graduation and
academic failure rate. Although the LD students’ high school records, ACT scores, and college performance were inferior to
that of the RSS group, they graduated at the same rate and within the same time frame. Neither was there any significant difference
in the academic failure rate. Closer examination of the LD graduates and academic failures’ performance showed that in spite
of the similarities in intellectual abilities, academic achievement, and aptitude-achievement discrepancy, two factors differentiated
between the LD graduates and non-graduates: oral language abilities and motivation and attitude toward the teaching-learning
process. These two factors accounted for 60 percent of the variance in graduation status.

The secondary worlds created in fantasy encourage the reader to compare and contrast the real world with the imaginary. In
this way, fantasy as a genre can be transformative. In this article, the dystopia created in The Giver (1993) by Lois Lowry
is examined as a metaphor for racism. After exploring the young adult novel as mystical fantasy in the context of reader response
theory, the author evaluates the monochromatic world of The Giver as a portrayal of the consequences of a colorblind stance.
Pedagogical considerations and implications for practice are also discussed.

serves as Chair, Board of Trustees, The Agnes Irwin School, an independent girls day school in Rosemont, PA. Her areas of
research include how aesthetic response and co-constructed meaning are enhanced through well-known visual art presented in
intertextual sets of picturebook art parody, local public mural art parody, and original artwork.
