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

Economic relations between China and Latin America have grown rapidly over the past decade. This paper documents the growth of trade, foreign direct investment (fdi) and other financial flows between China and Latin America and identifies the interests of China in the region as a source of raw materials, a market for exports of manufactured goods and an area of diplomatic competition with Taiwan. It points to the asymmetric nature of the relationship in terms of the relative importance of bilateral trade to each partner, the composition of trade flows, and the balance of fdi flows. It shows that these show many of the characteristics of centre–periphery relations. However, China is far from becoming a new hegemonic power in Latin America and the latter's relations with the USA and Europe continue to be more significant than those with China. 相似文献

We describe sibling proactive and reactive aggression in middle and late adolescence. Participants were 8th (n?=?303, M age?=?13.74 years, SD?=?.59) and 12th (n?=?300, M age?=?17.73 years, SD?=?.56) grade adolescents who completed an in-school survey. Findings revealed that these adolescents were significantly more likely to engage in reactive than proactive aggression with their closest-aged sibling. However, 8th grade adolescents reported greater aggression toward their closest-aged sibling than did 12th grade adolescents. In addition, sex composition of the sibling dyad moderated the association between sibling relationship quality (i.e., warmth and rivalry) and both proactive and reactive aggression indicating unique links for brother-brother and older sister-younger brother pairs. 相似文献

This article explores the under‐representation of women at the Chief Executive Officer (CEO) levels of Western Australian (WA) local government. It draws on data collected from 21 second tier senior women managers about their perceptions and experiences of leadership within the sector, as well as their aspirations for CEO appointment. By applying critical gender analysis to the data, gender and specifically masculinity emerges as a significant and valued leadership attribute. While this analysis is not unique to local government, what sets the sector apart is its apparent disinterest in examining the reasons for, or the impacts of this continued leadership stereotype when at the same time Australian public and private institutions are challenging these traditional leadership models. This article points to fundamental weaknesses in the formal power structures and processes of local government that support deeply embedded biases about leadership. Perhaps the most significant contributor to these outcomes that emerged from the study is the apparent unencumbered power of Mayors and elected members over all aspects of CEO employment, especially recruitment. 相似文献

Scotland seems to be a counter-example to general theories of the relationship between language and national identity or nationalism. These theories point to three components in the ideology of language and nation—that being able to speak the national language is necessary for full national membership, that the national language is a core part of the nation's culture, and that the future of national political autonomy and the future of the national language are connected with each other. In Scotland, it has appeared that language is not central to national membership or culture, and language campaigning has not been central to the political campaigns for autonomy. The article presents new evidence, from the 2012 Scottish Social Attitudes Survey, which questions these beliefs about the relationship between language and national identity or nationalism in Scotland. 相似文献

It is known that US paper currency in the general circulation is contaminated with cocaine. Several mechanisms have been offered to explain this finding, including contamination due to handling during drug deals and the use of rolled up bills for snorting. Drug is then transferred from one contaminated bill to others during counting in financial institutions. The possibility of contamination of currency with other drugs has not been reported. In this study, the author reports the analysis of 10 randomly collected US$ 1 bills from five cities, for cocaine, heroin, 6-acetylmorphine (6-AM), morphine, codeine, methamphetamine, amphetamine and phencyclidine (PCP). Bills were immersed in acetonitrile for 2h prior to extraction and GC-MS analysis. Results showed that 92% of the bills were positive for cocaine with a mean amount of 28.75+/-139.07 microg per bill, a median of 1.37 microg per bill, and a range of 0.01-922.72 microg per bill. Heroin was detected in seven bills in amounts ranging from 0.03 to 168.50 microg per bill: 6-AM and morphine were detected in three bills; methamphetamine and amphetamine in three and one bills, respectively, and PCP was detected in two bills in amounts of 0.78 and 1.87 microg per bill. Codeine was not detected in any of the US$ 1 bills analyzed. This study demonstrated that although paper currency was most often contaminated with cocaine, other drugs of abuse may be detected in bills. 相似文献

Data was compiled from 126 morphine-involved cases investigated by the Office of the Chief Medical Examiner, State of Maryland, USA. An investigation was conducted into whether comparison of morphine concentrations from a central and peripheral site could be used to determine whether a morphine death was acute or delayed. Fifty cases were identified as 'acute' because the urine free morphine concentration by radioimmunoassay (RIA) was less than 25 ng/mL; 76 cases were classified as 'random' because they had a urine morphine concentration greater than 25 ng/mL by RIA. The average heart blood to peripheral blood morphine concentration ratio in the acute deaths was 1.40. The average heart blood to peripheral blood morphine concentration ratio in the random deaths was 1.18. Because there was considerable overlap between the two groups of data, the authors conclude that it was not possible to predict 'acute' opiate intoxication deaths versus 'delayed' deaths when the only information available is heart and peripheral blood free morphine concentrations. 相似文献

Correctional staff are instrumental in ensuring the success of any correctional institution; therefore, investigating how the work environment impacts correctional workers is essential. To determine the effects of supervisory consideration, supervisory structure, job variety, and perceptions of training on correctional staff job stress, job satisfaction, and organizational commitment, data from a survey of staff at a Midwestern private correctional facility were examined. The Ordinary Least Squares regression results indicate that each of the work environment factors had a significant impact on one or more of the three outcomes. Specifically, supervisory consideration and perceptions of training decreased job stress. Supervisory consideration, job variety, and perceptions of training had positive effects on job satisfaction. Finally, supervisory consideration, supervisory structure, job variety, and perceptions of training had positive relationships with organizational commitment. 相似文献

Testing for the presence of cocaine (COC) is common in postmortem and clinical laboratories. COC use may be detected by screening urine specimens for COC metabolite. In the forensic arena, screening positive results are confirmed by a more specific and sensitive technique, such as gas chromatography-mass spectrometry. This article reports the case of an individual who died of COC intoxication but whose immunoassay screen (EMIT) for COC metabolite was negative. Gas chromatography-mass spectrometry analysis of the urine detected benzoylecgonine (BE) at a concentration of 75 ng/mL and COC at 55 ng/mL. These concentrations explain the negative screening result since the cutoff concentration of the assay was 300 ng/mL for BE. The reported cross reactivity with COC was 25,000 ng/mL. However, heart blood concentrations of COC and BE were 18,330 and 8640 ng/mL, respectively. The results from this case provide evidence that an EMIT test alone may fail to detect COC use. Individuals utilizing results of drug screening by immunoassay must be aware of the limitations of this testing methodology. 相似文献
