Despite extensive sociological research on gender and organizations, criminologists have paid insufficient attention to how organizational context and market demands may shape the extent and nature of women's participation in illicit enterprises. This study uses an organizational framework to examine the case of Chinese human smuggling to the United States. Drawing from interviews with 129 human smugglers, we propose a gendered market perspective for understanding the place of women in the human smuggling enterprise. We argue that the limited place of violence and turf as organizing features of human smuggling, the importance of interpersonal networks in defining and facilitating smuggling operations, gender ideologies about work and caregiving, and the impact of safety as an overriding concern for clients combine to create a more meaningful niche for women in human smuggling operations than is found in other criminal endeavors. Our research suggests that organizational and market contexts are significant explanations for gender stratification in illicit enterprises.  相似文献

Tribulus terrestris is a nutritional supplement highly debated regarding its physiological and actual effects on the organism. The main claimed effect is an increase of testosterone anabolic and androgenic action through the activation of endogenous testosterone production. Even if this biological pathway is not entirely proven, T. terrestris is regularly used by athletes. Recently, the analysis of two female urine samples by GC/C/IRMS (gas chromatography/combustion/isotope-ratio-mass-spectrometry) conclusively revealed the administration of exogenous testosterone or its precursors, even if the testosterone glucuronide/epitestosterone glucuronide (T/E) ratio and steroid marker concentrations were below the cut-off values defined by World Anti-Doping Agency (WADA). To argue against this adverse analytical finding, the athletes recognized having used T. terrestris in their diet. In order to test this hypothesis, two female volunteers ingested 500 mg of T. terrestris, three times a day and for two consecutive days. All spot urines were collected during 48 h after the first intake. The (13)C/(12)C ratio of ketosteroids was determined by GC/C/IRMS, the T/E ratio and DHEA concentrations were measured by GC/MS and LH concentrations by radioimmunoassay. None of these parameters revealed a significant variation or increased above the WADA cut-off limits. Hence, the short-term treatment with T. terrestris showed no impact on the endogenous testosterone metabolism of the two subjects.  相似文献

Abstract: The purpose of this study was to develop age‐predicting equations from the anterior cortex of the femur of Korean adults. Seventy‐two femoral samples (44 male and 28 female) were obtained from Korean cadavers and used to develop the equations. The thin sections (<100‐μm thick) were prepared by manual grinding; the sections were not decalcified and were stained with Villanueva bone stain reagent. Analysis of covariance showed no significant differences in age‐adjusted histomorphological variables between sexes. In stepwise regression analysis, osteon population density, average osteon area, and the most anterior cortical width were selected for an age‐predicting equation which produced a high regression correlation (R2 = 0.789). The average Haversian canal area was not significantly related to age for any specimen.  相似文献

Research Summary Scholarly research has documented repeatedly that minority citizens are disproportionately stopped, searched, and arrested relative to their baseline populations. In recent years, policymakers have brought increased attention to this issue as law‐enforcement agencies across the United States have faced allegations of racial profiling. In the 1990s, the politics generated by accounts of racially biased policing placed heightened pressure on law‐enforcement agencies. However, to date, few studies have explored whether the increased social and political scrutiny placed on police organizations influenced or changed their general pattern of enforcement among black and white citizens. Using data in the search and citation file from the North Carolina Highway Traffic Study, this research specifically examined whether the politics generated by the media coverage of racial profiling and racial profiling legislation in North Carolina influenced the search practices of officers of the North Carolina State Highway Patrol's drug interdiction team. The findings suggest that media accounts and the passage of new legislation were particularly powerful influences, which thereby reduced racial disparity in searches. Declines in the use of consent searches and an increased probability of finding contraband also were influenced by the politics of racial profiling. Policy Implications The results of this study suggest several important policy recommendations. First, law‐enforcement agencies must monitor the policing practices of their officers because such supervision can influence officer compliance with fair and unbiased policing policies. Next, supervisors need to familiarize themselves with enforcement data to identify potential problem officers and organizational practices. By doing so, police organizations will not only increase officer accountability but also will potentially improve communication with their local communities. Such communication can empower community members to file charges against officers who violate their civil rights. Next, the media and political effects documented in this study suggest that external oversight can be particularly influential on police practices. Therefore, police agencies should consider developing a citizen complaint board, which is an external oversight board that would be responsible for investigating allegations against officers who engage in racial profiling or other racially biased enforcement practices. Such a board could assist police administrators in identifying problem officers as well as in making recommendations for corrective action. Finally, external social and political pressure must continually be placed on police forces to improve equity in police behavior. These external forces can assist in creating opportunities for police to increase the overall quality and efficacy of policing.  相似文献

Judging Police Misconduct: "Street-Level" versus Professional Policing   总被引:2,自引:1,他引:2  
In their interactions with citizens, police officers are prohibited from (1) using unnecessary Force, (2) Abusing their authority, (3) speaking Discourteously, or (4) using Offensive language, all captured by the acronym FADO. However, acts of police misconduct are complex social phenomena that involve both following legal guidelines and responding to extralegal or mitigating circumstances. Using a factorial survey of police‐civilian interactions that introduce various dimensions of FADO and surrounding circumstances, respondents are asked to rate from zero to ten the seriousness of police misconduct in an encounter. Findings show that respondents' judgments of the seriousness of misconduct consider both legal and extralegal dimensions. On the legal side of the ledger, officers' unnecessary use of force and use of offensive language significantly increase judgments of serious misconduct; on the extralegal side of the ledger, civilians' confrontational demeanor significantly reduces judgments of serious misconduct. The findings suggest that citizens expect officers to behave professionally, or by the book, but with a recognition that “street‐level” discretion has a place in an officer's toolkit. Citizens' expectations that street‐level discretion has its place is also demonstrated by findings for the dimension abuse of authority: Abuse or threatening behavior by officers is not a significant predictor of serious police misconduct. In addition, characteristics of the respondents explain propensities to observe different degrees of police misconduct. Controlling for the social status, political orientation, and prior experience of respondents with the police, we find that (1) blacks rate police misconduct significantly higher than their white counterparts, and (2) liberals rate police misconduct significantly higher than their conservative counterparts. Differences in judgments by blacks and whites and by liberals and conservatives concerning judgments of police misconduct have important implications for the legitimacy of police authority.  相似文献

The 2007 American automobile industry labor negotiations involved fundamental challenges for labor and management, including a historic shift of responsibility in the management of retiree health care, a need for new approaches to core employment security issues, identification of ways to create new unionized jobs in the industry, and a joint commitment to the competitive viability of U.S. operations. Less visible, but no less important in the United Auto Workers–Ford case, has been unprecedented levels of information sharing and unique innovations in the bargaining process designed to enable problem solving even when tough issues were on the table. More than 300 people were directly involved in the negotiations, serving at the main table and on twenty‐four subcommittees. This case study covers the context for the negotiations, key events leading up to the bargaining, a unique process of “bargaining over how to bargain,” the actual negotiation process, and the results achieved. Implications are generalizable to the broader concept of pattern bargaining and many other types of negotiations when transformation is on the table.  相似文献
