The Scent Transfer Unit (STU-100) is a portable vacuum that uses airflow through a sterile gauze pad to capture a volatiles profile over evidentiary items for subsequent canine presentation to assist law enforcement personnel. This device was evaluated to determine its ability to trap and release organic compounds at ambient temperature under controlled laboratory conditions. Gas chromatography-mass spectrometry (GC-MS) analyses using a five-component volatiles mixture in methanol injected directly into a capture pad indicated that compound release could be detected initially and 3 days after the time of collection. Additionally, 15 compounds of a 39-component toxic organic gaseous mixture (10-1000 parts per billion by volume [p.p.b.(v)]) were trapped, released, and detected in the headspace of a volatiles capture pad after being exposed to this mixture using the STU-100 with analysis via GC-MS. Component release efficiencies at ambient temperature varied with the analyte; however, typical values of c. 10% were obtained. Desorption at elevated temperatures of reported human odor/scent chemicals and colognes trapped by the STU-100 pads was measured and indicated that the STU-100 has a significant trapping efficiency at ambient temperature. Multivariate statistical analysis of subsequent mass spectral patterns was also performed. 相似文献

Political participation researchers have developed several evaluative techniques to assess the representativeness of political participation patterns. Yet, while the Internet has become a mainstream avenue for political participation in the United States, current assessments of online participation insufficiently apply these methods. To incorporate these methods we begin by drawing upon resource theory to inform two-stage ordered-logit models of online and offline political participation. Our results suggest that the factors predicting online participation often differ from the factors that predict offline participation. Even so, we find that those from higher socioeconomic backgrounds tend to disproportionately possess these distinct online determinants. Next, we use a wide spectrum of political opinion questions to determine whether online participators opinions reflect or distort those of the general population. Overall, we find that online participation tends to relate moderately with liberal preferences. However, because offline participation relates to political attitudes similarly, the Internet only marginally advantages the political voice of liberals. Finally, we discuss the implications of these results. 相似文献

The present article attempts to answer important questions about the most important thing learned from the past 20 years of research on sexual violence, the most important thing to be learned about sexual violence over the next 10 years, and the most promising methodological innovation in the study of sexual violence from the last 20 years. It is hoped that discussion of such important questions might further stimulate researchers and mental health professionals to continue making progress in our understanding of, as well as the struggle against, sexual violence. 相似文献

Mental health review bodies engage in complex decision-making that may explicitly incorporate a therapeutic philosophy. Examination of select decisions of the New Zealand Mental Health Review Tribunal offers a foundation for understanding some implications of a pro-therapeutic approach. This analysis draws upon therapeutic jurisprudence scholarship in relation to three aspects of the hearings as documented in the written decisions: advocacy, therapeutic intervention, and the dignitary potential of the proceedings. The research explores the unintended consequences of a pro-therapeutic approach and evaluates the potential application of therapeutic jurisprudence within a mental health law context. 相似文献

One of the most prominent claims to emerge from the field of public opinion is that citizens can vote for candidates whose issue positions best reflect their own beliefs even when they cannot remember previously learned stances associated with the candidates. The current experiment provides a unique and powerful examination of this claim by determining whether individuals with profound amnesia, whose severe memory impairments prevent them from remembering specific issue information associated with any particular candidate, can vote for candidates whose issue positions come closest to their own political views. We report here that amnesic patients, despite not being able to remember any issue information, consistently voted for candidates with favored political positions. Thus, sound voting decisions do not require recall or recognition of previously learned associations between candidates and their issue positions. This result supports a multiple memory systems model of political decision making. 相似文献

If the OECD??s Development Co-operation Report for 2009 is correct in its claim that ??The international aid effort now adds up to less than the sum of its parts??, then continued rapid growth in aid transfers is likely to contribute to further aid absorption problems, as well as institutional atrophy and deteriorating governance and corruption control among aid recipients. This article considers aid for good governance and anti-corruption, using Tanzania as an example. ??The supply side of aid?? sketches the bigger picture in which such aid is located, stressing collective action problems facing the aid industry in the current period of growth and diversification. ??The consequences of aid proliferation on corruption control in an aid-dependent state?? provides some empirics from Tanzania. ??Conclusions: whither ??corruption control????? draws some conclusions for the future of aid for governance and corruption control. A key message is that donor-driven governance and corruption control initiatives have failed to address the governance weaknesses that excessive and uncoordinated aid has helped to create. 相似文献

The purpose of this paper is to use criminological theories to explain chronic drunk driving. There is little criminological research explaining recidivist drunk driving with criminological theories. Instead, most researchers posit that repeat drunk driving is explained as a byproduct of substance abuse. Although substance abuse is likely correlated to chronic drunk driving, theoretical explanations need to go further to understand a broader set of social and psychological predictors. Factor analysis and linear regression techniques are used to estimate the relationship between items from two assessment instruments with a number of drunken driving offenses. The sample consists of nearly 3,500 individuals on probation and parole in a Southwestern state. The findings support our contention that criminological frameworks are helpful to understand chronic DUI. We found significant results for volatility, antisocial friends, teenage deviance, and negative views of the law, while controlling for age, gender, marital status, and race. DUIs are a serious problem for the criminal justice system and understanding the individual level correlates of repetitive DUI is crucial for policy development. Further, chronic DUI offers criminologists an opportunity to determine the ability of criminological theories to explain this type of behavior. 相似文献
