Evidence based on almost 300,000 sexual assaults from the National Incident-Based Reporting System showed that the modal age of victims was 15 years, regardless of the age of the offender, the gender of the offender, or the gender of the victim. We suggest that adolescents have the highest risk of victimization because of their sexual attractiveness, vulnerability, and exposure to motivated offenders. As a result of these factors, sexual assault is as much an offense against young people as it is against women. The sexual attractiveness of young people also has implications for the age of offenders. Older men have much higher rates of offending than one would expect, given the age-desistance relationship. Thus, we found that older men have much higher rates of sexual assault than physical assault. Finally, evidence suggested that homosexual men were at least as likely as heterosexual men to commit sexual assault. The pattern suggests that the tendency for sexual assaults to involve male offenders and female victims reflects male sexuality rather than attitudes toward women.
We examine whether economic crimes are committed to fund drug addiction and/or to fund a hedonistic lifestyle. To address motivation, we estimate reciprocal relationships between economic crime and drug use and between economic crime and hedonistic activity generally. Analyses are based on event calendar data collected from 715 male offenders. Both simultaneous (within-month) relationships and effects involving a 1-month lag are examined. Offenders were more likely to engage in property crime and drug dealing during months in which they used hard drugs, marijuana, and alcohol, and when they engaged in more frequent unstructured socializing. The results from lagged models suggested that hedonistic activities lead to economic crime and economic crime creates opportunities for more frequent hedonistic activity.
We use data from the National Incident‐Based Reporting System (NIBRS) to examine the effects of age on the risk of sexual and physical assault in prisons and jails. Our evidence suggests that male inmates of all ages tend to sexually assault young men. The preference for the young is much stronger for sexual than for physical assault, which suggests that the young are sexually assaulted because of their sexual attractiveness rather than because of their vulnerability. We argue that the strong relationship between sexual attractiveness and age reduces opportunities for consensual sex among older inmates. As a result of blocked opportunities for consensual sex, older men are much more likely to commit sexual assault than one would expect, given the general tendency of young men to be more violent. Thus, the age–attractiveness relationship can parsimoniously explain the contrasting age patterns one observes for offenders and victims.
Mastery learning approaches were designed to improve student learning and elevate the level of understanding across a broader swath of students. These approaches operate under the belief that all students are capable of learning if given enough time. Little research has examined the utility or applicability of a mastery learning approach for social sciences outside of research methods courses. This study provides a review of the relevant literature on mastery learning, a discussion of the applicability of this approach to the teaching and learning of social sciences, and a review of the process and results of the conversion of more traditionally organized and taught courses to a mastery learning approach. Overall, our evaluation provides evidence that a mastery learning approach can make a significant impact on student learning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
