This paper provides a comparative snapshot of the current state of the law in the US and UK with respect to potential liability of university and college students for use (and misuse) of social networking sites. It reviews the limited case law on this topic, highlights the differences in the two nations’ laws of defamation and the various possible legal claims available to individuals allegedly harmed by postings on these social networking sites, and concludes that neither country currently offers a satisfactory legal or quasi-legal model for resolving these disputes.  相似文献

When policies incentivize voluntary activities that also take place in the absence of the incentive, it is critical to identify the additionality of the policy—that is, the degree to which the policy results in actions that would not have occurred otherwise. Rebate programs have become a common conservation policy tool for local municipalities seeking to retrofit residential properties with efficient appliances. This research evaluates whether such rebates can be cost‐effective means for water utilities to promote water conservation. A unique database is developed that combines water‐use data over a three‐year period for all households that participated in a utility's high‐efficiency toilet (HET) rebate program, water‐use data for a matched sample of neighbors who did not receive a rebate, and a survey of rebate participants. Difference‐in‐differences models indicate that installation of an HET reduces household water consumption by approximately 7 percent. While installation of an HET appears to be an effective means for achieving household reductions in water consumption, our results also suggest that the rebate program is a much less effective means for achieving household reductions in water consumption. Specifically, the rebate program is found to provide limited additional water savings beyond what would have occurred naturally and is responsible for only 37 percent of the total water reduction attributable to the installation of HETs over the study period. © 2013 by the Association for Public Policy Analysis and Management.  相似文献

The domestic violence advocacy and family court communities have each grown dramatically over the last three decades. Although these professional communities share many values in common, they often find themselves at odds with one another on a host of issues. This article examines the practical, political, definitional, and ideological differences between the two communities and calls for them to join forces and collaborate on behalf of children and families.  相似文献

In many of the major migrant-sending countries of the developing world, governments have extended political rights to expatriates, often including the right to vote via absentee ballot. Little is known about the factors that shape transnational electoral participation, however. Using official records provided by the Mexican Federal Electoral Institute, we model the incidence of expatriate ballot solicitations prior to the 2006 presidential election in Mexico. Based on a series of event count regression analyses conducted at the level of U.S. metropolitan statistical areas, we find that transnational involvement in the election depended not only on socioeconomic factors but also on the concentration of Mexican civic associations within the local community, the presence of Spanish-language media, and distance from the Mexican border. This suggests that the roots of immigrant transnational participation include factors familiar to social scientists as well as dynamics uniquely relevant to immigrant communities.  相似文献

In the last five years the forces of organised right-wing extremism have made electoral advances across many states in contemporary Europe. Germany has not been immune and the extreme right party, the National Democratic Party of Germany won its first seat in the European Parliament since 1989. The recent successes of the extreme right pose issues for European society about tolerance and immigration policy, but this scene has also been associated with an upsurge in racially motivated political violence and acts of right-wing terrorism. Much of this violence is perpetrated by small neo-Nazi styled groups. This paper looks at the most notorious and recent of such groups to emerge in Germany, the National Socialist Underground. The paper explores the origins and personalities behind this terror cell, provides derails of its criminal activities and murder spree, and questions why it took so long for the authorities to identify the NSU.  相似文献
