The Internet opens a vast array of communication, entertainment, and educational resources for children; however, it also opens a gateway to home and school for offenders who wish to exploit children. A convenience sample of 225 cases published in the news media was examined. The cases were classified using law enforcement terminology to describe Internet offenders as traders, travelers, or combination trader-travelers. The media is seen as a critical source of information for the public to be aware of how the Internet is being used to commit sexual exploitation and sex crimes against children.  相似文献

This paper illustrates one strategy for testing a theory ofeconomic influences on voting. We use a competitive equilibriummodel of the economy to determine the impact of an individual'seconomic position on his or her economic interests and, ultimately,political interests. We then test whether this impact is observedin voting behavior, addressing the resulting specification andestimation problems in the context of U.S. presidential electiondata. Our empirical results suggest that, despite these formidableproblems, we can usefully connect political—economic modelsand discrete-choice (probit) models of voting.  相似文献

Two studies were conducted to investigate the relationship between several nonintellectual personal attributes and satisfaction with acceleration among intellectually gifted students. First, two cohorts of gifted students (top 1% in ability and separated in age by five years) who had utilized acceleration during the course of their education were surveyed at age 18 and again at age 23. Overall, no strong relationships were found between satisfaction with acceleration and the nonintellectual factors at either age. Second, similar analyses were conducted for a subgroup of subjects, using the Adjective Check List and the Study of Values. Again, few significant correlations were found; the correlations that were statistically significant were small. These findings indicate that some non-intellectual personal attributes, which are often assumed important to the selection of students for acceleration or to the evaluation of participants in accelerative programs, actually may not be appropriate for these purposes.This research was supported by grants to Camilla Benbow from the National Science Foundation (MDR-8651737 and MDR-8855625) and an anonymous service agency. Further support was provided by scholarships to Mary Ann Swiatek from Oberlin College and from the Kappa Kappa Gamma Fraternity.Received M.S. in counseling psychology from Iowa State University.

A longitudinal study of 114 women, all having serious problems in intimate relationships, recruited from the community was undertaken in order to investigate relationship and battering status over time. In the original sample (N=193), 97 women were battered and 96 were not battered, as determined by an adaptation of the Conflict Tactics Scale. Of the 114 who returned approximately 2 and 1/2 years later, only 25% of the 51 originally battered women were still in that category. Discriminant function analysis using a combination of variables from established instruments (depression, self-esteem, physical symptoms, self-care agency) and in depth interview (education, relationship control, relationship duration, childhood abuse) failed to distinguish those battered from those not abused at Time 2. Results do not support a learned helplessness model for most women experiencing abuse, and they suggest that battered women seen in the health care and/or social services systems should be supported in a process of healthy decision making about their relationship status.  相似文献
