This paper describes and analyzes the structural and operational features of Chinese alien smuggling. Interviews with aliens, smugglers and law enforcement officials in China, Hong Kong and the U.S. reveal this activity to be a complex process comprising a number of distinct operational stages. Our data suggest Chinese alien smuggling groups vary in their level of organization but most are best understood as task forces, or small groups of people assembled to perform a particular piece of work. These task forces are typically linked to international social networks characterized by overlapping, dyadic relationships; a high level of role differentiation; and a limited degree of hierarchy. Such groups are highly responsive to changing socio-legal and market constraints.The study was supported in part by a grant from California State University. The authors are grateful to John Galliher for his comments and suggestions, and would like to thank Jorge Guzman and Darwin Chen of the U.S. INS for their assistance with the project. An earlier version of this paper was presented at the annual meeting of the American Society of Criminology, Miami, 1994. 相似文献

Abstract. One of the theses of the present work is that, at the strictly logical and methodological level, practical logic has neither made, nor can it make any contribution to the philosophy of law, since none of the three branches of practical logic that have been taken into account, namely, the logic of norms, deontic logic and legal logic, seems to be theoretically possible. The contribution of practical logic to the analysis of legal language is assessed in terms of both the instruments of analysis elaborated by practical logic, the artificial languages, and the results obtained in two capital subjects, the negations of norms and the permissions. 相似文献

A single-column procedure on Bond Elut Certify for systematic toxicological analysis of drugs in plasma and urine. 总被引:1,自引:0,他引:1
A single-column solid-phase extraction procedure was developed for the screening of acidic, neutral, and basic drugs from plasma. The recoveries of all 25 tested drugs exceeded 82%. After the plasma had been diluted with phosphate buffer (pH 6.0), the drugs were extracted using a single Bond Elut Certify column. The acidic and most of the neutral drugs were eluted by acetone/chloroform (1:1) and the basic drugs were eluted by 2% ammoniated ethyl acetate. Some neutral drugs appeared in both fractions. The two fractions were collected separately and evaporated until approximately 100 microL of solvent remained in the tube. Both fractions were analyzed separately on a gas chromatograph equipped with a wide-bore capillary column and a flame ionization detector. The procedure could also be used for urine samples. 相似文献

Despite grand visions of a cosmopolitan planet living in peace, the first globalization at the turn of the 20th century descended into World War I as the old empires scrambled to preserve themselves as others sought self‐determination. Powers on the losing end of that war reasserted themselves in yet another worldwide calamity within decades. After World War II, in the early 1950s, with the victorious American‐led alliance in the driver's seat, institutions such as the United Nations and the Bretton Woods arrangements created a global stability that enabled peace, prosperity and the “rise of the rest.” In 2014, the world order is shifting again with the rise of China reviving in Asia the very kind of nationalist rivalries that led Europe to war twice in the 20th century. Will we be able to build new institutions that accommodate the new powershift without resorting to war, or will the second globalization collapse as well? Top strategists from the US, Japan and China respond to this momentous question. 相似文献

Using a comparative perspective, this paper explores two approaches to child/adult relationships and the practice of corporal punishment: a human rights perspective and a traditional perspective reflected in U.S. law. Source material for our analysis draws on statutes, court decisions, and human rights conventions relating to the status of children and corporal punishment. Legislation and case law reflecting each perspective are presented and analyzed. Discussions of the nature of and reasons for differences include: the absence of human rights principles as a touchstone for U.S. law, the avoidance of linking corporal punishment and violence in the law, and the persistence of a colonial model of child/adult relationships structured around adult dominance and control of children. In contrast, a human rights model has at its core the human dignity of the child. This approach extends human rights to children and discourages corporal punishment and oppressive relationships between adults and children. Finally, this paper discusses the value of bringing a human rights approach to our understanding of child/adult relationships and the use of corporal punishment against children. 相似文献

A rapid and highly species-specific real-time polymerase chain reaction (PCR) assay has been developed for the detection of capercaillie DNA (Tetrao urogallus) in meat and meat mixtures. The method combines the use of capercaillie-specific primers, that amplify a 142bp fragment of the mitochondrial 12S rRNA gene, and a positive control primer pair that amplifies a 141bp fragment of the nuclear 18S rRNA gene from eukaryotic DNA. SYBR(?) Green dye or TaqMan(?) fluorogenic probes were used to monitor the amplification of the target genes. Results obtained with the use of TaqMan(?) probes as detection platform increased the specificity of the real-time PCR assay in comparison with the results obtained using SYBR(?) Green. The proposed real-time PCR assay represents a rapid and straightforward method for the accurate identification of capercaillie that could be used by law enforcement agencies as a tool for the control of poaching and illegal trade of meat from this protected species. 相似文献

Cardiac fibromas are benign conditions; however, their location and size may cause ventricular arrhythmias and sudden cardiac death. We report a case of a 68‐year‐old female who died suddenly. Postmortem investigation detected a huge cardiac fibroma in the pars muscularis of the interventricular septum, occupying almost the entire muscular septum, and restricting the volume of left ventricular chamber. Histological examination revealed numerous foci of calcification in the alternating complex interlacing or strictly parallel collagenous fiber mass. Tumor mass was mainly demarcated, but in some places, fibrous infiltration of surrounding working cardiac muscle was found. We present a case when direct tumor involvement in the descending left bundle branches was evidenced. Mainly, the branches of septal fascicle were disrupted, entrapped, and degenerated by the tumor mass. This case report emphasizes that postmortem histological examination of conduction system in all sudden cardiac death cases may substantially improve the accuracy of postmortem diagnosis. 相似文献

Abstract: Synthetic cannabinoid agonists are chemically diverse with multiple analogs gaining popularity as drugs of abuse. We report on the use of thin layer chromatography, gas chromatography mass spectrometry, high‐performance liquid chromatography, and liquid chromatography time of flight mass spectrometry for the identification and quantitation of these pharmacologically active chemicals in street drug dosage forms. Using these approaches, we have identified the synthetic cannabinoids JWH‐018, JWH‐019, JWH‐073, JWH‐081, JWH‐200, JWH‐210, JWH‐250, CP47,497 (C=8) (cannabicyclohexanol), RCS‐4, RCS‐8, AM‐2201, and AM‐694 in various commercially available products. Other noncannabinoid drugs including mitragynine have also been detected. Typical concentrations of drug in the materials are in the range 5–20 mg/g, or 0.5–2% by weight for each compound, although many products contained more than one drug. 相似文献
