AbstractRachel Fleming and Kristin Calvert of Western Carolina University discuss their study of interlibrary loan borrowing requests in the three years surrounding a journal cancellation project. Noting that the impact of such a cancellation on interlibrary loan has not been studied since the 1990s, they examine numerous facets of requests for cancelled and non-cancelled journals, including request per journal, year of article requested, and request history for newly cancelled journals. Though journal cancellations resulted in a 2 percent increase in interlibrary loan requests, this number proved so small that Calvert and Fleming judged that their cancellations caused no undue effects. 相似文献

The purpose of this article is to review evidence concerning the joint impact of family characteristics and child care experiences in understanding children's development. Although child care experiences are related to children's development across a variety of domains, family characteristics, particularly socioeconomic status and parenting quality, are typically stronger predictors of children's outcomes. An important implication of these findings is that high-quality child care experiences are likely to have stronger effects on children who are at risk of poorer outcomes because of less optimal family environments; evidence from experimental and nonexperimental studies generally supports this conclusion. From a policy perspective, an important goal for future research is to identify subgroups of families within the heterogeneous low-income population that are in particular need of relatively more intensive services and to develop effective interventions that are tailored to their needs. 相似文献

Imprecise measures of ovulation obscure the relationship between women's sexuality and the menstrual cycle, as does studying women with different contraceptive goals in different social contexts. Here we present a novel noninvasive method to precisely pinpoint the preovulatory surge of Luteinizing Hormone (LH), demarcating hormonally distinct cycle phases with greater than 95% reliability. Women were more sexually active on days prior to and including the preovulatory (LH) surge. This pattern was evident only when women initiated sexual activity and not when their partners did, indicating an increase in women's sexual motivation rather than attractiveness. A second study replicated the 6-day increase in sexual activity beginning 3 days before the LH surge, accompanied by stronger sexual desire and more sexual fantasies. We propose the term 'sexual phase' of the cycle, since follicular phase is over inclusive and ovulatory phase is not sufficient. These findings are striking because the women were avoiding pregnancy and were kept blind to the hypotheses, preventing expectation bias. The sexual phase was more robust in women with regular sexual partners, although the increase in sexual desire was just as great in nonpartnered women, who also reported feeling less lonely at this time. We use these results to evaluate potential neuroendocrine mechanisms underlying women's sexual motivation and activity. 相似文献

This paper describes a knowledge representation approach and reasoning implementation in a real-time knowledge-based control system (KBCS) for navigating ships in restricted waters. This shipboard piloting expert system (SPES) is being developed as an intelligent node in Sperry Marine's ExxBridge integrated ship's bridge system (IBS) for Exxon Shipping Company tankers. The SPES is intended to provide decision support to ships' navigation officers while piloting large vessels in restricted waters, and to reduce the information overload under which they labor, by incorporating local, transit-specific, and shiphandling knowledge, and by providing requisite decision support in a timely fashion. As such, the system provides decision support to (1) senior ships' pilots training junior pilots; (2) ships' masters training junior deck officers in the essentials of good piloting and shiphandling; and (3) watchstanding deck officers utilizing the system's on-line reminder and assist capabilities, or off-line simulation and contingency planning functionality. 相似文献

Emotional Connection (EC) measured by the Welch Emotional Connection Screen (WECS) was related to the Parent–Infant Interaction Rating System (PIIRS), a 5‐point adaptation of the rating system developed for the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (e.g., NICHD Early Child Care Research Network, 1999, Developmental Psychology, 35, 1399). Parent–infant dyads (n = 49 mothers; 43 fathers) were videotaped during face‐to‐face interaction at infant age 6 months; interactions were coded with both the WECS and PIIRS. At age 3, mothers completed the Child Behavior Checklist. WECS ratings of EC were associated with PIIRS rating items for both mother–infant and father–infant dyads. Mother–infant EC related positively to maternal sensitivity and positive regard for child, child positive mood and sustained attention, and dyadic mutuality, and negatively with maternal intrusiveness. Father–infant EC related positively to fathers' positive regard for child, child positive mood and sustained attention, and dyadic mutuality. Mother–infant EC predicted child behavior problems at age 3 better than mother–infant PIIRS ratings of dyadic mutuality. With fathers, neither EC nor dyadic mutuality ratings predicted mother‐reported child behavior problems. Findings highlight the practical utility of the WECS for identifying potentially at‐risk dyads and supporting early relational health. 相似文献

The authors examined the relations among intimate partner violence (IPV), maternal depressive symptoms, and maternal harsh intrusive parenting. Using a cross‐lagged, autoregressive path model, they sought to clarify the directionality of the relations among these 3 variables over the first 2 years of the child's life. The results indicated that, in this diverse sample of families living in predominantly low‐income rural communities (N = 705), higher levels of early IPV were associated with increases in maternal depressive symptoms, which in turn were associated with increases in maternal harsh intrusive parenting behaviors. These findings suggest that interventions aimed at improving the parenting of women exposed to domestic violence may want to simultaneously target IPV and depressive symptomatology. 相似文献
