While the fertility effects of improving teenagers’ access to contraception are theoretically ambiguous, most empirical work has shown that access decreases teen fertility. In this paper, we consider the fertility effects of access to condoms—a method of contraception not considered in prior work. We exploit variation across counties and across time in teenagers’ exposure to condom distribution programs in schools. We find that access to condoms in schools increases teen fertility by about 12 percent. The results suggest that the effects of condom access varied significantly across different programs; the positive fertility estimates are driven by communities where condoms are provided without mandated counseling. Programs that mandated counseling have zero or negative fertility effects, but estimates on these counties are less robust across specifications. 相似文献

Correctional staff are instrumental in ensuring the success of any correctional institution; therefore, investigating how the work environment impacts correctional workers is essential. To determine the effects of supervisory consideration, supervisory structure, job variety, and perceptions of training on correctional staff job stress, job satisfaction, and organizational commitment, data from a survey of staff at a Midwestern private correctional facility were examined. The Ordinary Least Squares regression results indicate that each of the work environment factors had a significant impact on one or more of the three outcomes. Specifically, supervisory consideration and perceptions of training decreased job stress. Supervisory consideration, job variety, and perceptions of training had positive effects on job satisfaction. Finally, supervisory consideration, supervisory structure, job variety, and perceptions of training had positive relationships with organizational commitment. 相似文献

Use of online social networking sites such as Facebook has burgeoned in the last 5 years. We examine these sites as facilitators
of Online Obsessive Relational Intrusion (o-ORI)—a much-talked about, but relatively un-researched online phenomenon. We draw
parallels between the types of behaviors conducted online and those identified in the literature on relational intrusion and
its more extreme relative, stalking. We present a frequency analysis of students’ behavior on Facebook and find evidence of
relational intrusion from both offenders and targets. The behaviors can be classified into five different categories, including:
primary contact attempts, secondary contact attempts (i.e., contacting others connected to the target), monitoring or surveillance,
expressions, and invitations. We conclude that Facebook facilitates behaviors that are indicative of obsessive relational
intrusion and that such behaviors have implications for users’ privacy and security. 相似文献

We examined forensic fingerprint examiners' suitability determinations of latent fingerprints comparing situations in which the latent is assessed solo (in isolation) versus situations in which it is presented alongside a comparison (matching or non-matching) exemplar print. The presence of a non-matching comparison exemplar led examiners to be more inclined to draw the conclusion that the latent was suitable for comparison compared to when the latent was presented solo. This effect persisted even when the latent presented was highly unsuitable for comparison. The presence of a matching comparison exemplar led examiners to be less likely to decide that the latent was suitable and more likely to decide the latent was questionable compared to solo analysis. This effect persisted even when the latent presented was highly suitable, suggesting a strong main effect. Knowledge of another examiner's previous determination that the latent was unsuitable was found to increase the likelihood that the examiner would conclude that the latent was unsuitable. However, knowledge of a previous “suitable” determination by another examiner did not increase the likelihood of a “suitable” conclusion by examiners. The finding that effects were weaker, although not entirely removed, in those with IAI certification suggests that training may be an appropriate route for reducing the effect of contextual influence and bias in suitability determinations. It was also shown that latent prints that were previously classed as "unsuitable" in a non-biasing context, continued to be judged to be "unsuitable" in a strongly biasing context (a major case in which a previous examiner was purported to have made an Individualization). 相似文献

This study investigates whether depression in women who experienced intimate partner violence is associated with having also experienced childhood sexual and physical abuse, psychological abuse by an intimate partner, recent involvement with the abusive partner, and bodily pain. Fifty-seven women who had left a violent relationship with an intimate partner completed measures assessing their demographic characteristics, experiences of abuse in childhood and in their relationship with their intimate partner, and depressive symptoms. Multiple regression analysis showed that women's depression was significantly greater among those who had experienced childhood physical and sexual abuse, more severe psychological abuse, and greater bodily pain (p<.001), adjusted R(2)=.32. These results suggest characteristics that can help to identify abused women who are most at risk for depression, and they suggest specific issues that may need to be addressed in this population. 相似文献

Experts play a critical role in forensic decision making, even when cognition is offloaded and distributed between human and machine. In this paper, we investigated the impact of using Automated Fingerprint Identification Systems (AFIS) on human decision makers. We provided 3680 AFIS lists (a total of 55,200 comparisons) to 23 latent fingerprint examiners as part of their normal casework. We manipulated the position of the matching print in the AFIS list. The data showed that latent fingerprint examiners were affected by the position of the matching print in terms of false exclusions and false inconclusives. Furthermore, the data showed that false identification errors were more likely at the top of the list and that such errors occurred even when the correct match was present further down the list. These effects need to be studied and considered carefully, so as to optimize human decision making when using technologies such as AFIS. 相似文献

Early term birth is defined as birth at 37 or 38 weeks gestation. While infants born early term are not considered premature, the medical literature suggests that they have an increased risk of serious adverse health outcomes compared to infants born at term (39 or 40 weeks). Despite these known harms, we document a rise in early term births in the United States from 1989 to the mid‐2000s, followed by a decline in recent years. We posit that the recent decline in early term births has been driven by changes in medical practice advocated by the American College of Obstetricians and Gynecologists, programs such as the March of Dimes’ “Worth the Wait” campaign, and by Medicaid policy. We first show that this pattern cannot be attributed to changes in the demographic composition of mothers, and provide some evidence that efforts to reduce early term elective deliveries (EEDs) through Medicaid policy were effective. We next exploit county‐level variation in the timing of these changes in medical practice to examine the effect of early term inductions (our proxy for EEDs) on infant and maternal health. We find that early term inductions lower birth weights and increase the risks of precipitous labor, birth injury, and required ventilation. Our results suggest that reductions in early term inductions can explain about one‐third of the overall increase in birth weights between 2010 and 2013 for births at 37 weeks gestation and above. 相似文献
