Information from 422 cases of child mistreatment in Toronto was gathered from the files of a child welfare agency and a children's hospital. These data were compared to patterns reported in previous studies and clinical writings on child mistreatment to investigate similarities and differences in families whose children have been abused in Canada, England, and the United States. Findings from the present study were similar to others in many respects. The differences were primarily in the area of lower incidences of such problems as perinatal difficulties in the children and intellectual limitations and social isolation in the parents; however, there was a higher incidence of single-parent families. The results suggest that clinicians should bear in mind that child mistreatment cannot be ruled out on the grounds that no serious problems have been noted for the child or the family. 相似文献

What do students stand to gain from high-stakes, standardized testing? We consider answers to this question from the perspective of urban district leaders tasked with designing and overseeing the implementation of standardized testing policies. Results revealed variation in leaders’ framing of and rationale for standardized testing with respect to benefits for students and whether/why students should strive for high test scores. Implications for both approaches to standardized testing and broader improvement initiatives are discussed. 相似文献

Black and White students who enrolled in college by age 20 were selected from a national probability sample, in order to estimate the prevalence of having children and the effect of having a child on probability of graduation with a bachelors degree. Black students reported significantly higher rates of having children than White students, but rates for Black students at historically Black universities were similar to those of Black students at predominantly White universities. After controlling for family background, achievement, and other student characteristics, having a child within 5 years of starting college generally reduced the probability of graduating with a bachelors degree for Black women and White women and men. The independent effect of attending a historically Black college was significantly positive for Black women but not statistically significant for Black men. 相似文献

One important socio-cultural medium through which young children’s moral understanding is cultivated is parent/child discourse. Of particular interest to us was young children’s use of basic (‘thin’) evaluative concepts (good, bad, right and wrong), which are ubiquitous in everyday discourse and serve as a potential bridge from the non-moral to the moral domain. We investigated 14 2–5-year-old children’s (and their parents’) use of thin evaluative concepts and found that while they frequently used good and bad to morally evaluate other people’s and their own psychological/dispositional states and behaviors—as well as, less frequently, to highlight relevant standards, expectations and rules—they did not use right and wrong. In contrast, a sample of US written and spoken public conversation revealed that adults did. Reasons for this are discussed, along with the frequency of different types of moral evaluations, differences between children and their parents, and age-related trends. 相似文献
