There are management and organizational problems common to both legal and illegal businesses, such as moving one party to act in the interest of another rather than his own. In principal-agency theory, the party that wants someone else to do a job on his behalf is called the “principal” and the other party is called the “agent”. Principal-agency theory tries to find solutions to real and potential conflicts that arise from such transactional arrangements. We believe principal-agency theory has great potentials for understanding the operation and interpersonal relationships of criminal enterprises, in addition to the structural arrangements (e.g., a disorganized crime market) and the social network perspectives. Using a case study of Chinese loan sharking and cannabis cultivation in the Netherlands, we seek to make a theoretical contribution to existing literature on organized crime by focusing on how different individuals within a criminal enterprise negotiate the most efficient transactional arrangement in a principal-agent relationship amidst the uncertainties of an illicit market environment. We specifically look at four phases of the criminal enterprise studied: the selection of agents by the principal, attempts to bind these agents to the principal, potential conflicts and finally the solution of any problems. Incidentally, our study also gives insight in the less well-researched topic of loansharking.  相似文献

A statistical procedure is developed to analyze recidivism in samples whichare subject to the presence of desisters and to multiple modes ofreconviction. This allows for a more accurate study of individuals'transition and hazard in the type and timing of offenses following aspecific type of conviction. The use of a nonparametric approach forinvestigating failure in the presence of other acting causes is shown;initial estimators of the probabilities of reconviction for different typesof offenses are obtained, and the method can be used both to display thedata and to choose an appropriate parametric family for the survivaltimes. An exponential mixture model for competing risks is presented insuch a way that it allows us to adjust for concomitant variables and toassess their effects on the probabilities both of reconviction forpredetermined types of offenses and desistance and of the hazards ofreconviction; a method for assessing calibration of predicted survivalprobabilities is suggested. A 21-year follow-up of persons convicted ofindecent assault on a female in 1973 illustrates the methods; we find ahigh probability of sexual reconviction for individuals with previoussexual convictions and evidence of diversity and a raised hazard ofreconviction for young chronic offenders.  相似文献

In considering the question “How will we fight?”, this article begins by examining the threats we face from conventional, insurgent, and hybrid enemies as well as terrorists and super-empowered individuals. It then outlines how America can fight effectively against each threat—as well as identifying the deficiencies in our current force structure that will hinder that response. The analysis argues that America needs a well-balanced, medium-weight joint force. It then provides recommendations for each of the services, as well as special operations forces, to achieve that goal. It concludes by describing what is needed to insure our force is capable of the rapid innovation in wartime required of successful nations.  相似文献

Fatal falls from heights (?3 m) often result in blunt force trauma (BFT) to the skeleton. The fracture patterns that result from this BFT mechanism are well understood in forensic anthropology and forensic pathology; however, details of the specific types of fractures that result remain poorly documented. The aim of this study was to provide a detailed examination of the types of fractures that may result from fatal high falls. Fractures were recorded from 95 full‐body postmortem computed tomography scans of individuals known to have died from a high fall. Trauma was then analyzed taking into account the extrinsic and intrinsic variables known to influence a fall using multiple logistic regression. A total of 339 types of fractures were classified, of which 16 were significantly associated with this BFT mechanism. Classified fracture types will augment anthropological interpretations of the circumstances of death from BFT in cases of suspected high falls.  相似文献

Research has documented a negative relationship between religion and risky sexual behavior. Few studies, however, have examined the processes whereby religion exerts this effect. The present study develops and tests a model of various mechanisms whereby parental religiosity reduces the likelihood of adolescents’ participation in risky sexual behavior (early sexual debut, multiple sexual partners, and inconsistent condom use). Structural equation modeling, using longitudinal data from a sample of 612 African American adolescents (55% female), provided support for the model. The results indicated that parental religiosity influenced adolescent risky sexual behavior through its impact on authoritative parenting, adolescent religiosity, and adolescent affiliation with less sexually permissive peers. Some mediating mechanisms differed by the gender of the respondent, suggesting a “double-standard” for daughters but not for sons. Findings also indicated the importance of messages about sexual behavior that are transmitted to adolescents by their peers. Theoretical and policy implications of the findings are discussed.  相似文献

The body of an unidentified elderly woman was found trapped in a floodgate. Prior to autopsy, full-body multislice computed tomography (MSCT) was performed for study of bone lesions and cause of death. Age was estimated by analysis of the sternal end of the fourth rib and of the pubic symphyseal medial articular surfaces. The results were then compared with the autopsy findings. MSCT was superior to autopsy in diagnosis of traumatic bone lesions and also revealed dental anomalies and signs of drowning. Age estimation gave a similar result for both methods. This case report illustrates the potential value of MSCT for medico-legal investigations of death: diagnosis of injuries, possibility of determining the cause of death, and anthropological study in order to estimate age or to visualize features likely to enable identification of a corpse.  相似文献
