This study investigated and evaluated the safety margins of the continuous long duration (up to 30 min) effect of the TASER X26 waveform, using a Sus scrofa model. Long duration continuous stimulus has not been evaluated on humans or human surrogates prior to this study. Swine were used as models due to similarities with humans in their skin and cardiovascular systems. Very long duration was used to determine both exposure dose and possible adverse physiological effects of dose. The trial began with an application of 10 min, and subsequent animals received increasing exposure time up to a survived maximum duration of 30 min. At the onset of this work, it was hypothesized that there would be a time limit after which most animals would not survive consistent with increased dose response. However, this hypothesis was not supported by the experimental results. All animals (10 of 10) survived up to 3 min. Seven of the 10 animals survived up to a 10‐min exposure and 3 of 5 animals with a 30‐min target exposure survived the full exposure. Surviving animals were recovered and observed for 24 h, with no postrecovery deaths. This suggests that swine (based on physiology) will not experience a fatal event when exposed to the TASER X26 for a continuous 3 min. Conclusions regarding longer duration (10–30 min) are not as certain due to the small sample sizes at these time intervals. 相似文献

Despite increased interest in environmental crime and green criminology, few studies address the use of criminal penalties in response to environmental crimes. A handful of published examples employ data from the United States or the Flanders court system, and little is known about how other nations punish environmental violations. Addressing this issue, the current study examined the use of criminal environmental penalties in Ireland from 2004 to 2014. Few criminal environmental cases (N = 147) and few environmental offenders (N = 154) were represented in these data over time. Consistent with the expectations of green/environmental crime researchers, mean penalties for environmental violations, which in Ireland only include fines and investigative cost recovery penalties, were rather small. Unlike in the US or Flanders, the majority of offenders were corporate offenders as opposed to individuals. Contextual factors related to Ireland’s economy, history and use of criminal sanctions should be used to interpret these factors, and prevent generalising from these data. 相似文献

Using a data set that covers all Portuguese mainland municipalities for the period 1979–2005, this study performs an empirical analysis of the economic determinants of mayors’ decisions to run for another term in office. The literature on the subject is mainly centered on the United States and, as far as we know, there are no papers addressing the economic factors influencing those choices. Probit panel estimations show that local economic conditions matter more than the national or regional economic environment. The results also confirm that political variables are important and that they influence the likelihood of seeking reelection in much the same way as they affect vote and popularity functions. 相似文献

Many studies have focused on the relationship between political information and the use of ideology. Here, we argue that two “evaluative motivations”—general investment of the self in politics and extremity of partisanship—serve as moderators of this relationship. Specifically, we use data from two recent national surveys to test whether the possession of information is more strongly associated with a tendency to approach politics in an ideological fashion among individuals high in both types of evaluative motivation. Results supported this hypothesis, revealing that information was more strongly associated with ideological constraint and with a tendency to give polarized evaluations of conservatives and liberals among those who highly invest the self in politics and those with more extreme partisanship. As such, this study suggests that information and involvement interact to shape the use of ideology. 相似文献

Political scientists have documented the many ways in which trust influences attitudes and behaviors that are important for the legitimacy and stability of democratic political systems. They have also explored the social, economic, and political factors that tend to increase levels of trust in others, in political figures, and in government. Neuroeconomic studies have shown that the neuroactive hormone oxytocin, a peptide that plays a key role in social attachment and affiliation in non-human mammals, is associated with trust and reciprocity in humans (e.g., Kosfeld et al., Nature 435:673–676, 2005; Zak et al., Horm Beh 48:522–527, 2005). While oxytocin has been linked to indicators of interpersonal trust, we do not know if it extends to trust in government actors and institutions. In order to explore these relationships, we conducted an experiment in which subjects were randomly assigned to receive a placebo or 40 IU of oxytocin administered intranasally. We show that manipulating oxytocin increases individuals’ interpersonal trust. It also has effects on trust in political figures and in government, though only for certain partisan groups and for those low in levels of interpersonal trust. 相似文献

From its inception in 1947 until the late 1970s the primary missions of the United States Military Liaison Mission (USMLM) involved maintaining a presence in East Germany for confidence building measures and reporting on items related to indicators and warnings of hostilities initiated by the Soviet Army. While not abandoning its traditional missions, the unit underwent a major transformation in the early 1980s and became the first Humint integrated collection, analysis and production center. Through a combination of factors, USMLM was able to link targeting, single-source collection and analysis while providing insights in a wide range of areas, from nuclear weapons, troop morale, equipment production, technical data, health and ethnic issues and literacy. Most significantly, USMLM confirmed severely reduced manning levels in GSFG combat arms units.

Much of the theoretical work on preferences for redistribution begins with the influential Melzer–Richard model, which makes predictions derived both from position in the income distribution and the overall level of inequality. Our evidence, however, points to limitations on such models of distributive politics. Drawing on World Values Survey evidence on preferences for redistribution in 41 developing countries, we find that the preferences of low-income groups vary significantly depending on occupation and place of residence, union members do not hold progressive views, and inequality has limited effects on demands for redistribution and may even dampen them.

Upon entering office, Carter Administration officials placed a heavy emphasis on integrating human rights into United States foreign policy. They also sought to contain festering Arab–Israeli tensions in the Middle East. The intersection of these two issues was the Israeli–Palestinian conflict. This article examines the Administration's attempts to solve that conflict and to bring peace to the region. It argues that policymakers developed a sincere dedication to safeguarding Palestinian rights, but that their understanding of those rights was limited in scope and defined through the lens of United States security and strategic interests. In spite of a good-faith effort to satisfy Palestinian desires while maintaining a constructive relationship with Israel, the Administration ultimately failed to alter the status quo because of regional developments. As Washington's strategic thinking changed, so did the urgency of Palestinian rights. 相似文献
