Liverpool Law Review - Has there ever been a law criminalizing mental states in themselves? We show that there has been, and still is: the Treason Act 1351. We argue for what we call ‘the...  相似文献

With rapid urbanisation, millions of people from rural areas have migrated to major cities for employment, leaving their young children at home. This labour migration creates substantial mental and physical challenges for these left-behind children. This study establishes two empirical models for comparing the health status of left-behind children with that of children in rural areas without migrant parents and with that of migrant children in urban areas. Our empirical findings reveal that parental migration negatively affects the height and weight indices of left-behind children. The effects are particularly prominent for younger children, when both parents migrate or when parents migrate out of province.  相似文献

This article explores the hypothesis that people in less democratic nations will use the Internet newsgroups devoted to those countries as a relatively ‘safe’ form of political discussion and even protest. Also, it is expected that nationals of those countries living overseas will use these newsgroups to more openly discuss politics in those nations than they could otherwise do so. Before turning to a content analysis of the messages posted in non‐United States Usenet groups, the number of these groups and the levels of political discussion in them are quantified. The article quantifies the international usage of the Usenet as a first attempt to find some patterns in this usage that may be politically motivated. After all, many pundits imagine that the Internet will become the vaunted ‘global village’ and source of ‘grass‐roots democracy’, and not merely in the United States. An examination of the content of about 2500 messages in 41 Usenet groups then follows, with a view to establishing the following: how many messages are explicitly political; how many are in opposition to the current government; how many are pro‐government; whether they primarily serve as alternative sources of news; whether they are attempts to recruit people in the subject country and around the world into some sort of political action; and whether richer nations are more likely to have higher levels of discussion in their newsgroups than poorer ones. The findings conclude that newsgroups devoted to countries with lower levels of democratization have a much higher percentage of anti‐government messages than the newsgroups about nations that are more democratic.  相似文献

The relation between timing of first sex and later delinquency was examined using a genetically informed sample of 534 same-sex twin pairs from the National Longitudinal Study of Adolescent Health, who were assessed at three time points over a 7-year interval. Genetic and environmental differences between families were found to account for the association between earlier age at first sex and increases in delinquency. After controlling for these genetic and environmental confounds using a quasi-experimental design, earlier age at first sex predicted lower levels of delinquency in early adulthood. The current study is contrasted with previous research with non-genetically informative samples, including Armour and Haynie (2007, Journal of Youth and Adolescence, 36, 141–152). Results suggest a more nuanced perspective on the meaning and consequences of adolescent sexuality than is commonly put forth in the literature.
