Sugars and stearates (composed of fatty acids) are both frequent components used in the production of ecstasy tablets. Their analysis can therefore provide supplementary information useful for drug intelligence. Links established using these substances would be very significant as they should give us information about the manufacturer of the tablets. Two methods have been developed for the analysis of sugars and fatty acids by GC-MS and were applied to 109 ecstasy tablets. Characterisation of the samples should allow the differentiation of a certain number of them and furthermore their classification into groups. This is obtained by analysing the raw data using chemometric methods. Several pre-treatments have been tested together with six similarity measures on a small number of ecstasy samples in order to determine which combination would best characterise one ecstasy sample and differentiate it from the others at the same time. Normalisation followed by the fourth square and applied together with the squared cosine function appeared to give the best results and has been applied to all samples. The correlation values obtained of each sample with all others express the probability of a presence of a link between two samples. In order to verify the signification of these values, and thus of a link, all samples have been compared considering the data visually according to three selected criterions. The 109 examined samples could be divided into 67 groups, with 43 of them containing only one sample. Considering the distribution of their correlation values, sample pairs showing a value below 0.23 can be considered as linked. As the excipients are necessarily related to the blending, which also includes the active substance, and variation in the excipient content has been proven by the grouping of the samples, a low similarity value does indicate a link with regard to the producer. In conclusion, it appears that the result obtained with the excipients is certainly very valuable, but all other available information has to be taken into account as well before making any conclusions. 相似文献

International Comparison of Public and Private Employees’ Work Motives,Attitudes, and Perceived Rewards 下载免费PDF全文
This article presents a conceptual perspective on the distinctive characteristics of public organizations and their personnel. This perspective leads to hypotheses that public organizations deliver distinctive goods and services that influence the motives and rewards for their employees. These hypotheses are tested with evidence from the International Social Survey Programme in order to compare public and private employees in 30 nations. Public employees in 28 of the 30 nations expressed higher levels of public‐service‐oriented motives. In all of the countries, public employees were more likely to say they receive rewards in the form of perceived social impact. In most of the countries, public employees placed less importance on high income as a reward and expressed higher levels of organizational commitment.

- The findings presented here add to previous evidence that public employees seek and attain more altruistic and public‐service‐oriented rewards than private sector employees. In particular, we add evidence that these differences hold in many different nations and cultural contexts.
- Compensation and incentive system reforms in many governments have often concentrated on financial incentives and streamlining procedures for discipline and removal. Such matters are important but should not drive out concerns with showing public employees the impact of their work on the well‐being of others and on the community and society. Leaders and managers should invest in incentive systems that emphasize such motives and rewards.
- Leaders and managers should invest in the use of altruistic and socially beneficial motives and rewards in recruiting systems.

Shared Race/Ethnicity,Court Procedural Justice,and Self‐Regulating Beliefs: A Study of Female Offenders 下载免费PDF全文
Thomas Baker Justin T. Pickett Dhara M. Amin Kristin Golden Karla Dhungana Marc Gertz Laura Bedard 《Law & society review》2015,49(2):433-466
Using survey data from a sample of white, black, and Hispanic incarcerated females (N = 554), we examine if the theoretically hypothesized and empirically demonstrated relationship between procedural justice and obligation to obey the law is substantiated among a sample of offenders and explore the impact that sharing the race/ethnicity of the defense attorney and prosecutor in their most recent conviction has on female inmates' perceptions of court procedural justice and their perceived obligation to obey the law. The findings reveal that female offenders who perceive the courts as more procedurally just report a significantly greater obligation to obey the law. In addition, white female inmates who had a white prosecutor were significantly more likely to perceive the courts as procedurally just. Non‐whites, though, perceive the courts as more fair if they encountered a minority prosecutor regardless of whether the prosecutor was black or Hispanic. 相似文献

Evaluating Simulant Materials for Understanding Cranial Backspatter from a Ballistic Projectile 下载免费PDF全文
Raj Das Ph.D. Alistair Collins B.E. Anurag Verma B.E. Justin Fernandez Ph.D. Michael Taylor Ph.D. 《Journal of forensic sciences》2015,60(3):627-637
In cranial wounds resulting from a gunshot, the study of backspatter patterns can provide information about the actual incidents by linking material to surrounding objects. This study investigates the physics of backspatter from a high‐speed projectile impact and evaluates a range of simulant materials using impact tests. Next, we evaluate a mesh‐free method called smoothed particle hydrodynamics (SPH) to model the splashing mechanism during backspatter. The study has shown that a projectile impact causes fragmentation at the impact site, while transferring momentum to fragmented particles. The particles travel along the path of least resistance, leading to partial material movement in the reverse direction of the projectile motion causing backspatter. Medium‐density fiberboard is a better simulant for a human skull than polycarbonate, and lorica leather is a better simulant for a human skin than natural rubber. SPH is an effective numerical method for modeling the high‐speed impact fracture and fragmentations. 相似文献

Exaggerating good governance: Regime type and score inflation among executive survey informants 下载免费PDF全文
Researchers and policymakers often rely on executive surveys to understand and promote good governance. In doing so, they assume that the evaluations provided by these well‐informed respondents are not systematically influenced by regime type. However, regime‐embedded executives often have a personal stake in the survey outcomes, incentivizing them to exaggerate good governance. This paper compares World Economic Forum Executive Opinion Survey responses to corollary measures of key governance concepts in democracies, anocracies, and autocracies. It finds evidence of significant score inflation among executives in closed regimes. The individual‐level mechanisms are explored in one autocracy by comparing responses from regime‐embedded informants based at firms headquartered within the country with those managing businesses headquartered abroad. These micro‐level data likewise reveal evidence of widespread inflation, particularly on items related to governance. Finally, a closer look at Transparency International's Corruption Perceptions Index demonstrates the broader impact Executive Opinion Survey inflation for measuring governance within closed regimes. 相似文献

In recent years Duncan Kennedy has turned to the question, what is Contemporary Legal Thought? For the most part, his answers have focused on the modes of legal argument he believes are indigenous to Contemporary Legal Thought in the United States, and possibly, at a transnational or global level as well. In this article, I bracket the question of content and ask instead, if we are interested in exploring the category of a legal ‘contemporary’, how do we do so? What historiographic methods are well-suited to the task of constituting ‘Contemporary Legal Thought’? My focus here is entirely on legal structuralism, the historical method I associate with Kennedy’s work beginning in the 1970s. By the mid-1980s, legal structuralism was under assault and quickly fading from the repertoire of available styles of doing history on the left. By the turn of the century, legal structuralism appeared to have vanished. I think that this was regrettable and unnecessary, and in this article I argue for a return to structuralist historiography. I do not pretend, however, that this return entails a second coming of the totalizing, originary center. Rather, I encourage thinking about legal structuralism in the way that I understand Roland Barthes, Hayden White, and to a large extent Duncan Kennedy himself to have thought about it: as a style. And as a style, legal structuralism is worth reawakening, a style back in style once more. 相似文献

Objectives
Despite its widespread adoption by more than two-thirds of police departments in the US, there has not been a single study examining the effects of the TASER on cognitive functioning. This inquiry is important for two reasons. First, research has consistently documented cognitive deficits following exposure to electricity (the TASER is an electrical device). Second, questions have emerged regarding whether TASER exposure impairs suspects’ ability to understand and waive their Miranda rights.Methods
To explore this issue, the authors carried out a pilot study with 21 police recruits who received a TASER exposure as part of their training at the San Bernardino County (CA) Training Center. Each recruit was given a battery of cognitive tests 3–4 h before TASER exposure, within 5 min after exposure, and again 24 h after exposure.Results
Recruits experienced statistically significant reductions in several measures of cognitive functioning following TASER exposure. However, all recruits had returned to their baseline levels of functioning within 24 h. Learning effects were documented in several of the cognitive tests.Conclusions
The questions driving this study involve serious issues including constitutionally protected rights of the accused, use of force by police, and previously unexamined effects of the TASER on the human body. The pilot study represents a critical first step in exploring the effects of the TASER on cognitive functioning. Moreover, the results provided the authors with important information that will guide their larger study, a randomized controlled trial where healthy human volunteers will be randomly assigned to four groups, two of which receive a TASER exposure. 相似文献150.
