A longitudinal study of 25 families, with children aged 14 months—5 years, in joint custody, is reported. Varying motivations that lead divorcing parents to undertake and sustain joint custody are discussed, together with the stresses and gratifications of these arrangements for the parents and children. Findings are that where both parents are motivated primarily by interest in the child, where the parenting is sensitive and where the child is shielded from interparental conflict, young children do well. Such families were not the majority in this study. Significant differences emerged in the adjustment of the 1–3 age group as compared with the 3–5 age group which point to greater difficulties for the 3–5 year-olds. 相似文献

This paper explores a popular yet highly destructive form of property crime — graffiti vandalism. The localities of such destruction
selected for study were male and female restrooms. Three hundred and ninety-two cases were collected and analyzed. Prior research
theorized the existence of a significant difference in the amount of graffiti produced between the sexes. (It was believed
that males produce more graffiti than females). Analysis, however, revealed equal production of graffiti by males and females.Content differences between the sexes were hypothesized. The content categories included homosexual, heterosexual, nonsexual (humorous
and political statements) and racial graffiti. The findings as they relate to content differences between the sexes are presented
and discussed relative to sex-role socialization theory. 相似文献

Samples of blue and red cotton fibres were examined using light and fluorescence microscopy as well as UV/VIS microspectrophotometry and fluorescence microspectroscopy. The degree of fluorescence and spectral variation was recorded. Particular attention was paid to the recurrence of certain spectral patterns. The importance of spectral information in the UV range is emphasized again. Colour plays a critical role in the comparison of cotton fibres in forensic sciences. Normally, fibres producing spectral patterns that are frequently seen will tend to have a lower evidential value in criminal cases as the choice of putative sources is theoretically greater and vice versa. Besides black cotton, blue and red cotton fibres are very frequent in fibre casework. The very high discriminating power using a combination of light microscopy, fluorescence microscopy and UV/VIS microspectrophotometry shows that even blue and red cotton fibres can provide excellent evidence when involved in fibre transfer cases. 相似文献

Many law enforcement agencies are currently responding to the problem of online crime by establishing proactive investigative units that track criminals on the Internet. Not only do these specialized teams face problems in the area of emerging technology, they are also faced with handling emerging legal issues. The current research examined the issue of the entrapment defense, and how previously established physical realm doctrine could be applied to the investigation of online crimes such as child pornography. Relying on previous case law it would appear that entrapment claims related to online sting operations involve consideration of: a) did the law enforcement officer continuously contact the suspect with the intention of trying to convince the individual to engage in a particular type of behavior, b) how long was the relationship between the undercover officer and the suspect, and c) how much, if any, reluctance to commit the criminal act did the suspect provide evidence of? 相似文献

Despite their increasing importance, there is little theoretical understanding of why nation-states initiate economic sanctions or what determines their success. These events are often explained away as "symbolic politics" driven completely by domestic-level factors. This article develops a simple game-theoretic model of economic coercion to show that both "senders" and "targets" of economic coercion incorporate expectations of future conflict as well as the short-run opportunity costs of coercion into their behavior. Conflict expectations have a paradoxical effect on coercion events. First, senders that anticipate frequent conflicts will be more willing to initiate economic coercion, even if such attempts are costly. Senders that anticipate few conflicts will not threaten sanctions unless they incur minimal costs and the target would suffer significantly. While a robust anticipation of future disputes might make the sender prefer a coercive strategy, it also reduces its ability to obtain concessions. Target states that anticipate frequent conflict with the sender will make fewer concessions. Ironically, a sender will obtain the most favorable distribution of payoffs when it cares the least about its reputation or the distribution of gains. These hypotheses are tested statistically, with the results strongly supporting the conflict expectations model. 相似文献

What explains the persistence and proliferation of the resident ambassador? Why is the role apparently important both to the conduct of international affairs and to the work of governments? I do not try to propose a new theory of ambassadors, but I do offer conclusions about the nature of living in a globalized society of states where the economic logic of markets and the political logic of communities are at cross-purposes. It is a world in which we depend on institutions to help us maintain order and stability. Ambassadors are one of those institutions. At one level they are the concrete day by day reproduction of the society of states. At another level they act on behalf of the members of their community, helping that community to maintain its strength and cohesion by doing what needs to be done, abroad. An increase in the intensity of interactions among states, therefore, seems to lead to an increase in diplomatic representation facilitated rather than impeded by the new technologies of transportation and communications. Ambassadors are still lying abroad, it seems, because changes in technology have brought 'abroad' much closer to home while the myriad effects of globalization have made much more of abroad relevant to people and their governments. Far from being in decline, the resident ambassador seems likely to continue flourishing. 相似文献
