This article studies the impact of teacher absences on education. Using data spanning three academic years about 285 teachers and 8,631 predominantly economically disadvantaged students from a United States urban school district, it tests assumptions that a substantial portion of teachers' absences is discretionary and that these absences reduce productivity – students' mathematics scores. Since absent teachers are typically replaced by less qualified substitutes, instructional intensity and consistency may decline: ten days of teacher absence reduce students' achievement score by about 3.3 per cent of a standard deviation – enough to lower some students' designation in the state proficiency system and, thus, their motivation to succeed.  相似文献

In this paper, we tested the resource dilution hypothesis, which posits that, because parenting resources are finite, the addition of a new sibling depletes parenting resources for other children in the household. We estimated growth curve models on the self‐reported parenting practices of mothers using four waves of data collected biennially between 1994 and 2000 on a nationally representative sample of 2,082 Canadian children aged 2 to 5 at initial interview and in continuously intact, two‐biological‐parent households. Results showed that when new children were added to the household, mothers exhibited declines in positive interaction, but increased their levels of consistent parenting. Taken together, these findings suggested that parenting resources were reallocated, rather than diluted, when family size increased.  相似文献

Many young children born to unwed parents currently live with their biological mothers and their mothers’ new partners (social fathers). This study uses data from the Fragile Families and Child Well‐Being Study (N = 1,350) to assess whether involvement by resident social fathers is as beneficial for child well‐being as involvement by resident biological fathers and whether the involvement of the child’s nonresident biological father alters the relationship between resident social father engagement and child outcomes. Results indicate that involvement by resident social fathers is as beneficial for child well‐being as involvement by resident biological fathers and that frequent contact with the child’s nonresident biological father does not diminish the positive association between residential social father involvement and child well‐being.  相似文献

Using questionnaire data on 149 Dutch dual‐earner couples with young children participating in the European Famwork study, we examine how adaptive strategies and gender ideology relate to parents’ perceived success in balancing work and family. Path analysis indicates that some adaptive strategies may harm individuals’ work‐family balance, particularly when they are made in the domain where the time budget is limited. In the need to succeed in multiple roles, however, endorsement of traits traditionally linked with the opposite gender, that is masculine traits for women and feminine traits for men, seems beneficial. We speculate that two underlying mechanisms — social pressure and time constraints — jointly operate in determining perceived success in balancing work and family.  相似文献

Matching and attribute trade are two perspectives used to explain mate selection. We investigated patterns of matching and trade, focusing on obesity, using Add Health Romantic Pair data (N = 1,405 couples). Obese individuals, relative to healthy weight individuals, were less likely to have physically attractive partners, with this disadvantage greater for women than men, and greater for White women than Black women. Additional education, a more attractive personality, and better grooming increased the probability of having a physically attractive partner and offset the disadvantage of obesity for some individuals. Unexpectedly, we found women, like men, trade education for their partners’ physical attractiveness. Despite evidence of attribute trade, matching with respect to physical characteristics was the dominant mate selection pattern.  相似文献

Abstract We examine the prevalence of nonstandard employment in the nonmetropolitan United States using the Current Population Survey Supplement on Contingent Work (1999 and 2001). We find that nonstandard work is more prevalent in nonmetropolitan than in central city or suburban areas. Logistic regression models controlling for sociode‐mographic and work characteristics, show that nonmetropolitan workers experience higher odds of nonstandard employment than central city or suburban workers. Variations in industrial and occupational structures in nonmetro and metro areas do not explain residential differences in nonstandard work. We also estimate the odds of employment in each of the three components of nonstandard work: contingent work, part‐time, and varied hour work. Nonmetropolitan workers are more likely than central city and suburban workers to be employed in contingent or varied hour work. The benefits and wages of nonstandard work are lower than for standard work across residence areas. The results highlight the importance of understanding nonstandard work and the components of nonstandard work, particularly when considering the nature of work across industries, occupations, and residence.  相似文献

Based on ethnographic data, this article explains devotion to chess in terms of the structural mechanisms of its social organization. I use Lewis Coser's theory of greedy institutions as a way to analyze how these mechanisms influence player decisions and foster devotion to the game. Inspired largely by Randall Collins, I expand Coser's original framework by analyzing how the ritual of competitive play is structured in ways to heighten the intrinsic rewards of the game and further encourage commitment among the players. As such, devotion in chess is explained as a product of the following organizational elements: (1) isolation from competing social spheres; (2) encapsulation within a symbolic status structure; (3) a collective feeling of elite status; (4) trials of worthiness; and (5) prestructured ritual. After considering how these mechanisms operate in the world of chess, I discuss the potential of this expanded model of greedy institutions for future research across other social contexts.  相似文献
