The rapid economic growth in China over recent decades has been accompanied by higher levels of crime, but there have been few studies of the Chinese experience of criminal victimization. A recent victimization survey of a representative sample of households in Tianjin represents a major effort to fill this gap in the literature. The present paper reviews the research based on the Tianjin survey along with other studies of crime and criminal victimization in China that have been published since 1990. We summarize the major findings, discuss the theoretical perspectives and methodological strategies that have been applied, identify the limitations of the research to date, and offer suggestions for future research.

Identification particles used for the purpose of the post-blast identification of explosives have a coding system based on the combination of metal oxides and their various concentrations. These materials are composed of the polymeric matrix, iron powder (ferromagnetic properties), UV light active dyestuff and various metal oxides in a various ratios. A suitable analytical method has to be used for an accurate characterization of these metal components in the particles in order to find the required information, i.e. to determine the place and the year of production and as the case may be, also the production batch of misused explosives. In this work, the method of microwave digestion and flame atomic absorption spectrometry (F-AAS) was developed for an accurate determination of Zn, Mg, Cu and Pb in a few novel types of identification particles and applied to their characterization. When using specific sample treatment (digestion with a mixture of nitric acid with hydrochloric or hydrofluoric acid), the 3 sigma limits of detection (LODs) for the determination of Zn, Mg, Cu and Pb in 5mg original samples were 1.9, 0.2, 1.3 and 2.4 mg g(-1), respectively. The signal suppression due to the presence of HNO3+HCl or HNO3+HF was observed for Zn; therefore, the calibration solutions had to be prepared exactly with the same acids as those used for the sample mineralization. The determination of Mg, Cu and Pb was free of interferences; hence a simple calibration curve method could be adopted for attaining accurate results. The accuracy was checked by comparison of the results with those obtained by means of independent inductively coupled plasma optical emission spectrometry (ICP-OES). Good precision values, as relative standard deviation, in the range of 1-5% were obtained. A total number of 71 samples was analysed and classified by multivariate methods to prove the suitability of the procedure proposed for the purpose of the identification of explosives.  相似文献

Important research programs within New Institutional Economics advance culturalist arguments to explain failures of economic development. Focusing on the work of Douglass C. North and Avner Greif, this article argues that such arguments rely on an essentialist conception of culture that is both historically inaccurate and analytically misleading. Greif’s work in particular rests on a selective use of empirical data that ultimately distorts the deductive models that are at the core of his work. As a result, both scholars use culture to account for outcomes that are more adequately explained as the product of social conflict and political struggles—struggles in which culture plays a far more contingent and destabilizing role than the one they attribute to it. What is needed, I argue, is to link arguments about the persistence of inefficient institutions with a sociologically informed conception of culture as an ensemble of resources that enhance rather than constrain the scope of individual agency. To come to terms with the effects of culture on institutional formation and change it is necessary to replace the essentialism articulated by North and Greif with a strategic-instrumentalist view in which culture is compatible with a wide spectrum of economic behaviors, individual actions, and thus institutional trajectories.

A persisting question in international studies is whether academic research can have an impact on the making of foreign policy. Much research has shown that policy decisions can be greatly influenced by misperceptions, just as much as by objective factors. The article describes an effort by academic researchers to challenge U.S. policymakers' image of an actor in the U.S. foreign policy process—the American public. The study's focus was a widely held assumption in the U.S. foreign policy community that the American public in the wake of the Cold War was entering a renewed phase of isolationism, similar to the interwar years. The study first interviewed policy practitioners on their perceptions of the public, then performed a comprehensive review of existing polling data, and finally conducted new polls with input from policymakers themselves. The net result of the elite interviews and the analysis of public attitudes revealed a significant gap in all areas, which is presented in synopsis. Interviews with policy practitioners reveal two key dynamics that could well contribute to policymakers' misreading the public: a failure to seek out information about the public and a tendency to assume that the vocal public is representative of the general public. Indications that the study did have some impact on the thinking of policy practitioners are discussed in the conclusion.  相似文献

This is the first installment in what we hope will be a recurring series of Forums in ISP. In each segment we intend to provide an outlet for peer-reviewed dialogue and debate on important topics in the field and to allow our readers to discuss material previously printed in the pages of ISP. Below are two comments on "Challenging U.S. Policymakers' Image of an Isolationist Public" by Steven Kull and Clay Ramsay published in ISP 1:1. Both comments raise a number of important issues pertaining to the relationship of public opinion and foreign policy, and also address more general questions of domestic impact on foreign policy outputs and several significant methodological questions about approaches to polling. The Forum begins first with comments by Richard Clark and Kenneth Dautrich, is followed by comments from Shoon Murray, and concludes with a response from Kull and Ramsay.  相似文献

Performing point‐of‐care urine drug screen testing at autopsy by a forensic pathologist may provide an early indication of the presence of analytes of interest during autopsy. An evaluation for the screening of 14 classes of common drugs of abuse in postmortem urine by the point‐of‐care screening device, Alere iCup DX 14, is presented. One hundred ninety postmortem urine samples were screened with the iCup occurring at autopsy by the forensic pathologist. Positive and negative results obtained from the screening kit were evaluated against confirmatory test results obtained using routine forensic toxicology analyses that employed LC‐MS/MS and GC‐MS to detect a combination of over 85 common drugs of abuse and medications. Sensitivity for each respective iCup drug class ranged from 66% (buprenorphine) to 100% (methadone, tricyclic antidepressants). Specificity for each respective iCup drug class ranged from 89% (benzodiazepines) to 100% (amphetamines, barbiturates, buprenorphine, 3,4‐methylenedioxymethamphetamine, methadone). Positive predictive values ranged from 44% (benzodiazepines) to 100% (amphetamines, barbiturates, buprenorphine, methylenedioxymethamphetamine, methadone), while negative predictive values ranged from 96% (methamphetamine) to 100% (barbiturates, methadone, tricyclic antidepressants). A high false‐positive rate was yielded by the benzodiazepine class. The lack of fentanyl screening in the point‐of‐care device is a significant limitation considering its prolific prevalence in forensic casework. The results obtained in the study should be acknowledged when considering the use of the Alere iCup DX 14 in the context of postmortem casework to help indicate potential drug use contemporaneously with autopsy and when requiring such preliminary results prior to the release of a final forensic toxicology report.  相似文献
