Family conflict is exacerbated by poverty-related stress and is detrimental to adolescent mental health. Adolescent coping
with family conflict has the potential to buffer or exacerbate the negative effects of family conflict on internalizing symptoms.
We examined coping with family conflict among 82 low-income adolescents (53.7% female, mean age = 13.5 years at Time 1, SD = 1.98;
range 11–18), and their primary caregivers (95% female, mean age = 34.9 years, SD = 7.45). Adolescents were 25.9% Caucasian,
28.4% African American, 38.3% Hispanic, and 7.4% Other (Multi-racial, Native American, or Asian). Results show that family
conflict is more strongly associated with internalizing symptoms for adolescents under high levels of poverty-related stress.
Regression analyses indicate that secondary control coping moderates the effects of family conflict on internalizing symptoms.
In addition, analyses reveal that disengagement coping exacerbates symptoms across time for both adolescent girls and boys.
Regression analyses also suggest that primary control coping is helpful for coping with family conflict, but only for girls.
Results highlight the importance of examining coping concurrently and across time as well as including moderating effects
of gender. Intervention efforts targeting low-income adolescents should incorporate the instruction of secondary control strategies
for coping with family conflict. 相似文献

Children sometimes solve problems incorrectly because they fail to represent key features of the problems. One potential source of improvements in children's problem representations is learning new problem-solving strategies. Ninety-one 3rd- and 4th-grade students solved mathematical equivalence problems (e.g., 3 + 4 + 6 = 3 + __) and completed a representation assessment in which they briefly viewed similar problems and either reconstructed each problem or identified it in a set of alternatives. Experimental groups then received a lesson about one or both of two solution strategies, the equalize strategy and the add–subtract strategy. A control group received no instruction. All children completed posttest assessments of representation and problem solving. Children taught the equalize strategy improved their problem representations more than those not taught it. This pattern did not hold for the add–subtract strategy. These results indicate that learning new strategies is one source of changes in problem representation. However, some strategies are more effective than others at promoting accurate problem representation. 相似文献

Perceiving emotions correctly is foundational to the development of interpersonal skills. Five-month-old infants’ abilities to recognize, discriminate and categorize facial expressions of smiling were tested in three coordinated experiments. Infants were habituated to four degrees of smiling modeled by the same or different people; following habituation, infants were presented with a new degree of smile worn by the same and by a new person (Experiment 1), a new degree of smile and a fearful expression worn by the same person (Experiment 2) or a new degree of smile and a fearful expression worn by new people (Experiment 3). Infants showed significant novelty preferences for the new person smiling and for the fearful expressions over the new degree of smiling. These findings indicate that infants at 5 months can categorize the facial expression of smiling in static faces, and yet recognize the same person despite changes in facial expression; this is the youngest age at which these abilities have been demonstrated. The findings are discussed in light of the significance of emotion expression face processing in social interaction and infants’ categorization of faces. 相似文献

This study examined the moderating effect of exchange ideology on the relation between perceptions of organizational politics and manager-rated retention. Data collected from 178 employees of a distribution services organization indicated that employees’ perceptions of organizational politics related negatively related to manager assessments of retention. However, the variables were only related among employees with a moderate to strong exchange ideology. These individuals were more sensitive to a political environment than individuals with a weak exchange ideology. Implications for employees seeking to actively manage their careers are discussed. 相似文献

Using the bench trial of Colorado's Amendment 2 as an example, this article focuses on the more general question of expert testimony in moral philosophy. It argues that there is indeed expertise in moral philosophy but argues against admitting such expert testimony in cases dealing with what John Rawls terms "constitutional essentials" and 'matters of basic justice." Developing the idea of public reason inherent in the Rawlsian concept of political liberalism, the article argues that philosophers can and should speak out on public issues, if they do so with due respect for certain restrictions, but that they should not serve as expert witnesses on core constitutional questions, since doing so suggests that they claim a type of authority that would require fellow citizens to defer to their views. Such claims to authority in basic ethical matters threaten the mutual respect for divergent comprehensive doctrines that lies at the core of political liberalism. Philosophers have a duty to serve the public good, and they perform this service in fruitful ways. But they should refuse a public role that appears incompatible with equal respect for the committed ethical searching of their fellow citizens. 相似文献

Education for Citizenship in an Era of Global Connection 总被引:2,自引:0,他引:2
Martha Nussbaum 《Studies in Philosophy and Education》2002,21(4-5):289-303
Higher education makes an importantcontribution to citizenship. In the UnitedStates, the required portion of the ``liberalarts education' in colleges and universitiescan be reformed so as to equip students for thechallenges of global citizenship. The paperadvocates focusing on three abilities: theSocratic ability to critize one's owntraditions and to carry on an argument on termsof mutual respect for reason; (2) the abilityto think as a citizen of the whole world, notjust some local region or group; and (3) the``narrative imagination,' the ability to imaginewhat it would be like to be in the position ofsomeone very different from oneself. The paperdiscusses the role of the ``liberal arts'curriculum in U.S. education and asks howEuropean universities, with their differentstructure, might promote these three abilities. 相似文献
