The #MeToo movement has done a great deal to address sexual abuse and violence. There is no doubt that justice may occur when the right person speaks out. However, what happens when the wrong people—that is, people of color, the working class women, and transgender people— speak out on the same issue? When these “wrong people” do speak out, they are discredited, marginalized, and silenced by being ignored. This Viewpoint essay addresses two populations that have been overlooked by the #MeToo movement: women of color and transgender people. The essay concludes with recommendations for how the movement can move forward given the criticisms around the absence of diversity and transparency. 相似文献

Much attention has been paid to the nature of parent-adolescent relationships, with a frequent conclusion being that it is a time of marked disagreement between parents and their adolescents. However, other literature suggests that this time is not inherently conflictual. The purpose of this study was to examine agreement and disagreement between mothers, fathers, and adolescents on specific issues. Then, adolescent adjustment was assessed, and the degree to which it was a function of congruence with parents was examined. A modified version of the Issues Checklist was used to measure intrafamily agreement; the Revised Behavior Problem Checklist and the Harter Scale of Child's Actual Competence were completed by adolescents' social studies teachers to assess adolescent functioning. Relative to their parents, adolescents reported that they should make more decisions alone, while both mothers and fathers reported that decisions should be made jointly among all family members. Only father-adolescent congruence was found consistently to be related to adolescent functioning. Possible explanations for the present results and relevant issues pertaining to family agreement are discussed. 相似文献

This article discusses various models of children's out-of-school care arrangements, mainly in the United States of America. Forms of care include programs or centers, family day care homes, and self-care. The implications of each of these different systems of care and outcomes for both children and their parents are reviewed through the lens of existing research. While there is no consensus in the research literature, so-called “latch-key” children appear to experience more negative effects than supervised peers, although these negative effects may be mitigated by variables, such as the amount of time spent alone and the parent-child relationship. A small group of studies finds positive outcomes for children who participate in recreational after-school programs, although age-inappropriate care arrangements and age of participating child may be associated with negative outcomes. No research has been conducted across program types. Many mothers of school-age children without regular after-school care or alternative care on school holidays, appear to accomodate their career and work choices to their children's schedules, possibly in order to avoid the “latch-key” alternative. 相似文献

The premise that effects of maturational timing are mediated by social context is explored by comparing adolescent girls in dance and nondance schools. Because the dance student must maintain a relatively low body weight, being a late maturer (who is often leaner than an on-time maturer) is expected to be more advantageous to the dancer than to the student not required to meet a weight standard. Girls aged 14 to 18 were seen; 276 attended private schools and 69 attended national ballet company schools. AllSs were weighed and measured and asked questions about their secondary sexual development, weight-related concerns, eating concerns, adult sex-role expectancies, body image, emotional functioning, and family relationships. Menarcheal age was used to classify girls as early (before 11.5 years of age), on time (between 11.5 and 14 years), and late maturers (after 14 years). More dance than non-dance school students were late maturers (55% versus 29%). The dance students weighed less and were leaner, had higher eating scores, and had lower family relationship and impulse control scores than the comparison sample. Across groups, late maturing students weighed less, were leaner, and had lower diet and higher oral control scores than on-time maturers, with the differences more pronounced in the dance than nondance students. In addition, the on-time dancers had higher psychopathology, perfection, and bulimia scores and lower body image scores than the late maturing dancers. The findings are discussed in terms of a goodness of fit between the requirements of a social context and a person's physical and behavioral characteristics.This paper was prepared with the support of grants from the W.

To investigate the incidence and correlates of bulimic behavior, 1268 high school females were surveyed. A 47-item questionnaire was used to identify a group of students that would meet the DSM-III criteria for a probable diagnosis of bulimia. Students were then compared across the four content areas of demographics; body perception and weight information; dieting, exercise and menstrual behavior; and frequency of bingeing and purging behavior. Results indicated that 4.9% of the students met rigorous criteria for the diagnosis of bulimia. Between-group comparisons indicated that body dissatisfaction, drive for thinness, and chronicity of dieting differentiated the two groups.This work was supported by Biomedical Research Grant #RR5476, the Sears Allstate Foundation, and the George and Tina Barr Foundation.Main interest is eating disorders. 相似文献
