Abstract

Recently, researchers have devoted significant attention to the influence of turning points such as marriage, employment, and military service on criminal desistance in adulthood. Because offending peaks in adolescence, the relative lack of research on influential adolescent turning points is notable. Given the extensive research linking school failure to deleterious adult development, we propose that school failure (late grade retention and school dropout) is a marked transition in adolescence, with the potential to operate as a turning point in the life course. Using longitudinal data from the National Longitudinal Survey of Youth (NLSY79), we first examine structural, relational, and individual predictors of school failure in adolescence. Second, we assess whether school failure amplifies delinquency in late adolescence. We find evidence supporting our contention that school failure operates as an adolescent turning point, and we confirm that school failure is significantly predicted by structural, relational, and individual factors. Although school failure may be thought of as the end result of a long-term process of academic disengagement, our research suggests that it is also a pivotal, negative turning point in the life course.  相似文献

There exists a long-standing historiographical mystery concerning the legal origins of the practice of Spanish American slaves suing their masters for freedom in royal courts. This essay highlights the importance of working judges' judicial philosophy in the formulation of this customary ‘right’. A close reading of two rare eighteenth-century judicial opinions from Lima, Peru, exposes the rationale of the judges, particularly the Creole judges, who admitted slave cases. High court minister Pedro José Bravo de Lagunas y Castilla considered two legal issues that made slavery distinctive in the region: the right to self-purchase and grants of conditional liberty. In a 1746 letter, the judge rendered a relatively liberal opinion on slaves' legal rights by reading Creoles' own political ‘liberty’ into freedom suits. But as Lima's slaves increasingly entered the secular court system, his judicial philosophy would contract.  相似文献

In the civil construction industry sector, it has been observed that the increasing use of machines has made tasks noisier and consequently caused hearing loss and had other adverse effects on workers. The objective of this study was to identify and assess the physical risks of noise present in activities undertaken in a construction company in order to propose control measures which will contribute to the management of health and safety within the company's organization. The methodology applied was based on verifying the characteristics of exposure to noise on construction sites, from an observation of sources which generated noise and making measurements of sound pressure levels emitted by these sources. The data was then analyzed and compared with the recommended performance levels established in control measures. As a result, it was found that some machines and equipment used in civil construction often generate noise above the acceptable levels and as such, in these cases, various control measures have been proposed. It is believed that the use of management techniques is the most effective way to assess risk and to implement the preventive and corrective actions proposed, and allows for the analysis of sound pressure levels on an ongoing basis.  相似文献

In Experiment 1, it was investigated whether infants process facial identity and emotional expression independently or in conjunction with one another. Eight‐month‐old infants were habituated to two upright or two inverted faces varying in facial identity and emotional expression. Infants were tested with a habituation face, a switch face, and a novel face. In the switch faces, a new combination of identity and emotional expression was presented. The results show that infants differentiated between switch and habituation faces only in the upright condition but not in the inverted condition. Experiment 2 provides evidence that infants’ nonresponse in the inverted condition can be attributed to their independent processing of facial identity and emotional expression. This suggests that infants in the upright condition processed facial identity and emotional expression in conjunction with one another.  相似文献

Rates of sexually transmitted infections (STIs) are increasing in older cohorts in Western countries such as Australia, the United Kingdom, and the United States, suggesting a need to examine the safer sex knowledge and practices of older people. This article presents findings from 53 qualitative interviews from the study Sex, Age, and Me: A National Study of Sex and Relationships Among Australians Aged 60+. Participants were recruited through an online national survey. We consider how participants understood “safer sex,” the importance of safer sex to them, the safer sex practices they used (and the contexts in which they used them), and the barriers to using safer sex. Older adults had diverse understandings, knowledge, and use of safer sex practices, although participants tended to focus most strongly on condom use. Having safer sex was strongly mediated by relationship context, trust, perceived risk of contracting an STI, concern for personal health, and stigma. Common barriers to safer sex included erectile difficulties, embarrassment, stigma, reduced pleasure, and the lack of a safer sex culture among older people. The data presented have important implications for sexual health policy, practice, and education and health promotion campaigns aimed at improving the sexual health and well-being of older cohorts.  相似文献

The present experiment examined whether infants’ visual prediction performance of the appearance of objects moving in space is related to their manual object exploration ability. Fifty‐five 7‐ to 8‐month‐old infants were tested. A visual object prediction paradigm was developed during which a three‐dimensional object was presented in a live eye‐tracking setting. During familiarization, the object rotated back and forth along the vertical axis. While the object was moving, two target parts of it were briefly occluded from view and uncovered again as the object changed its direction of motion. In the test phase, the entire object was rotated around 90° and now rotated along the horizontal axis. We recorded infants’ eye movements directed at the target locations and analyzed the prediction rates. All of the infants also participated in a manual object exploration task, in which they freely explored five toy blocks. Infants with a higher level of object exploration skill had higher prediction rates during test trials as compared to infants with less proficient object exploratory actions. The results support the interpretation that advanced manual object exploration experience is associated with infants’ advanced visual prediction ability of the appearance of objects moving in space.  相似文献

Although research shows that involvement in crime varies across immigrant generations, less is known about why this is so. Using 13 waves of National Longitudinal Survey of Youth 1997 data, we examine the influence of marriage—a key correlate of desistance from crime—to understand more fully patterns of offending across immigrant generations during the transition to adulthood. Results indicate a lower prevalence of offending among first‐generation immigrants compared with their second‐generation and third‐plus‐generation peers; however, among active offenders, rates of offending are similar across groups. Notably, marriage exerts a significantly stronger effect on offending for second‐generation immigrants, suggesting that, while assimilation may be associated with more offending, it is also associated with a greater potency of marriage in promoting desistance from crime.  相似文献

Many methods have been proposed to solve the age-period-cohort (APC) linear identification problem, but most are not theoretically informed and may lead to biased estimators of APC effects. One exception is the mechanism-based approach recently proposed and based on Pearl’s front-door criterion; this approach ensures consistent APC effect estimators in the presence of a complete set of intermediate variables between one of age, period, cohort, and the outcome of interest, as long as the assumed parametric models for all the relevant causal pathways are correct. Through a simulation study mimicking APC data on cardiovascular mortality, we demonstrate possible pitfalls that users of the mechanism-based approach may encounter under realistic conditions: namely, when (1) the set of available intermediate variables is incomplete, (2) intermediate variables are affected by two or more of the APC variables (while this feature is not acknowledged in the analysis), and (3) unaccounted confounding is present between intermediate variables and the outcome. Furthermore, we show how the mechanism-based approach can be extended beyond the originally proposed linear and probit regression models to incorporate all generalized linear models, as well as nonlinearities in the predictors, using Monte Carlo simulation. Based on the observed biases resulting from departures from underlying assumptions, we formulate guidelines for the application of the mechanism-based approach (extended or not).  相似文献

Racial conflict has been at the center of US society since its inception. Various theories have tried to explain why racial conflict arises and what the motivating factors are. The aim of this article is to examine one of these theories––ethnic competition––by reviewing the sociological literature from the 1970s to present that focuses on racial interest, ethnic competition, and racial threat.  相似文献

Child maltreatment researchers have often suggested that experiences with child neglect have long-term, negative effects. Child neglect is thought to have particularly adverse effects on self-control, peer relations, and delinquency. In this research, we examine the relationship of child neglect with adolescent violence via self-control and peer rejection. Using prospective, longitudinal data from a community sample, we find that child neglect adversely affects peer rejection and violence. Neglected children were more likely to be rejected by their peers in early adolescence and were more likely to be violent later in adolescence. Contrary to theoretical predictions, child neglect was not a significant predictor of self-control. Implications for delinquency and child maltreatment researchers are discussed.  相似文献
