Using data from five waves of the Women’s Employment Survey (WES; 1997–2003), we examine the links between low-income mothers’
employment patterns and the emotional behavior and academic progress of their children. We find robust and substantively important
linkages between several different dimensions of mothers’ employment experiences and child outcomes. The pattern of results
is similar across empirical approaches—including ordinary least squares and child fixed-effect models, with and without an
extensive set of controls. Children exhibit fewer behavior problems when mothers work and experience job stability (relative
to children whose mothers do not work). In contrast, maternal work accompanied by job instability is associated with significantly
higher child behavior problems (relative to employment in a stable job). Children whose mothers work full-time and/or have
fluctuating work schedules also exhibit significantly higher levels of behavior problems. However, full-time work has negative
consequences for children only when it is in jobs that do not require cognitive skills. Such negative consequences are completely
offset when this work experience is in jobs that require the cognitive skills that lead to higher wage growth prospects. Finally,
fluctuating work schedules and full-time work in non-cognitively demanding jobs are each strongly associated with the probability
that the child will repeat a grade or be placed in special education. 相似文献

The concept of family homeostasis and related concepts such as family rules and family feedback mechanisms came under heavy fire in a recent article by Dell (1982). It is not easy to evaluate the arguments brought forth by Dell, since the concepts in question seem to have never been formally explicated. Most of this article is devoted to an attempt to develop such a formal explication. Dell's arguments are then examined one by one in the light of this explication, and most of them are shown to be mistaken. His main conclusion, that the concept of homeostasis should be replaced by a concept of coherence, is rejected. 相似文献

This article asks how state formation processes informed the normative frameworks of late-Medieval and early-Modern Latin European and Muslim Middle Eastern regimes. The question at hand is not why pre-Modern regimes discriminated against religious minorities (as well as other groups) during the pre-Modern period, but why Western European states consistently engaged in mass expulsions of their non-Christian subjects from the late thirteenth century onward and the neighboring states of the Middle East did not. Rather than addressing these peculiar policies as a function of religion, culture, or law the article adopts a comparative, contextual method. With the aid of Charles Tilly’s theoretical perspectives it isolates critical variables in pre-Modern Middle Eastern state formation. These variables are then used to shed light on the circumstances and relationships that led to Latin Europe’s mass expulsions of Jews and Muslims between 1290 and 1614. 相似文献

A speaker wishes to persuade a listener to accept a certain request. The conditions under which the request is justified, from the listener's point of view, depend on the values of two aspects. The values of the aspects are known only to the speaker and the listener can check the value of at most one. A mechanism specifies a set of messages that the speaker can send and a rule that determines the listener's response, namely, which aspect he checks and whether he accepts or rejects the speaker's request. We study mechanisms that maximize the probability that the listener accepts the request when it is justified and rejects the request when it is unjustified, given that the speaker maximizes the probability that his request is accepted. We show that a simple optimal mechanism exists and can be found by solving a linear programming problem in which the set of constraints is derived from what we call the L‐principle. 相似文献

This study supports itself in ergonomic concepts and usability criteria by prioritizing the identification and correction of problems found during the interaction of children with projected interfaces for them and left from the cognitive, interactional and interfacial difficulties caused by the excesses of color, elements and animation in sites and games, between them the difficulty of recognition of the information during the interaction with the elements of grid of the interface. The results of the methodology had proven that 78.38% of the 37 children got so absorbed by the game and forgot to fulfill their tasks, at least partially, and that the application of the supported ergonomic beddings in usability criteria is imperative. It is relevant to point out that the projetual activity of the game is centered in the user, the child, whose behavior is distinct and particular. Points that had been disclosed that had passed unobserved by the involved adults in this project, and that they had displayed the unappropriateness of some screens of the Spore? to the etária band due to the ambiguity of the game, besides, the children had been sensible to the clarity in some screens and had passed for unnecessary situations of stress. 相似文献

Although the consequences of teen births for both mothers and children have been studied for decades, few studies have taken a broader look at the potential payoffs—and drawbacks—of being born to older mothers. A broader examination is important given the growing gap in maternal ages at birth for children born to mothers with low and high socioeconomic status. Drawing data from the Children of the NLSY79, our examination of this topic distinguishes between the value for children of being born to a mother who delayed her first birth and the value of the additional years between her first birth and the birth of the child whose achievements and behaviors at ages 10–13 are under study. We find that each year the mother delays a first birth is associated with a 0.02 to 0.04 standard deviation increase in school achievement and a similar-sized reduction in behavior problems. Coefficients are generally as large for additional years between the first and given birth. Results are fairly robust to the inclusion of cousin and sibling fixed effects, which attempt to address some omitted variable concerns. Our mediational analyses show that the primary pathway by which delaying first births benefits children is by enabling mothers to complete more years of schooling. 相似文献

Income inequality and the achievement test score gap between high- and low-income children increased dramatically in the United States beginning in the 1970s. This article investigates the demographic (family income, mother’s education, family size, two-parent family structure, and age of mother at birth) underpinnings of the growing income-based gap in schooling using data from the Panel Study of Income Dynamics. Across 31 cohorts, we find that increases in the income gap between high- and low-income children account for approximately three-quarters of the increasing gap in completed schooling, one-half of the gap in college attendance, and one-fifth of the gap in college graduation. We find no consistent evidence of increases in the estimated associations between parental income and children’s completed schooling. Increasing gaps in the two-parent family structures of high- and low-income families accounted for relatively little of the schooling gap because our estimates of the (regression-adjusted) associations between family structure and schooling were surprisingly small for much of our accounting period. On the other hand, increasing gaps in mother’s age at the time of birth accounts for a substantial portion of the increasing schooling gap: mother’s age is consistently predictive of children’s completed schooling, and the maternal age gap for children born into low- and high-income families increased considerably over the period. 相似文献
