Based on ethnographic data, this essay analyzes the social order properties of a poor urban street, in a small city in the northeast United States, on which drug dealing is the principle occupation. Rather than treating drug dealing as an agent of disorder, we focus on the order properties of drug dealing and the ordered character of the local code of conduct that develops around it. Like Sudhir Venkatesh (American Journal of Sociology 103:82–111, 1997) we examine the interface between drug dealing and the neighborhood. However, in this small urban space the drug dealers are not outsiders, rather, they are long term residents: established insiders who are well integrated into community life. As such their work practices and the requirements they place on behavior in public spaces impact the neighborhood in comprehensive ways. We detail the phenomenon Elijah Anderson called the “code of the street” (Anderson 1999) as a set of practices and social markers, a local Interaction Order (Goffman, American Sociological Review 48:1–17, 1983; Rawls, Sociological Theory 2:136–149, 1987), that furnishes basic day to day sensemaking tools for residents (Rawls 2009). We propose that this order has a constitutive character that furnishes stable expectations (Garfinkel 1963, 1967) for meaningful social action and identity in the neighborhood. In a context of industrial decline and urban poverty, drug dealing careers constitute a major socialization factor, that touches everyone here—especially children.  相似文献

If the OECD??s Development Co-operation Report for 2009 is correct in its claim that ??The international aid effort now adds up to less than the sum of its parts??, then continued rapid growth in aid transfers is likely to contribute to further aid absorption problems, as well as institutional atrophy and deteriorating governance and corruption control among aid recipients. This article considers aid for good governance and anti-corruption, using Tanzania as an example. ??The supply side of aid?? sketches the bigger picture in which such aid is located, stressing collective action problems facing the aid industry in the current period of growth and diversification. ??The consequences of aid proliferation on corruption control in an aid-dependent state?? provides some empirics from Tanzania. ??Conclusions: whither ??corruption control????? draws some conclusions for the future of aid for governance and corruption control. A key message is that donor-driven governance and corruption control initiatives have failed to address the governance weaknesses that excessive and uncoordinated aid has helped to create.  相似文献

This study investigates the factors that shape the attitudes of scientists toward starting their own business or working in a private sector firm. The analysis is based on data collected from scientists working in the German Max Planck Society, a research institution devoted to basic science. We find that the scientists’ attractiveness of working in a private sector firm or of starting their own business differ considerably according to their academic discipline and the self-reported commercial potential of their research. The ability to take risks, prior work experience in private firms, and personal experience in cooperating with industry lead to a positive attitude towards switching to private sector employment or entrepreneurship. Strong willingness to freely distribute research findings is related to a low appeal of private sector work.  相似文献

Statutes criminalizing behavior that risks transmission of HIV/AIDS exemplify use of the criminal law against individuals who are victims of infectious disease. These statutes, despite their frequency, are misguided in terms of the goals of the criminal law and the public health aim of reducing overall burdens of disease, for at least three important reasons. First, they identify individual offenders for punishment, a paradigm that is misplaced in the most typical contexts of transmission of infectious disease and even for HIV/AIDS, despite claims of AIDS exceptionalism. Second, although there are examples of individuals who transmit infectious disease in a manner that fits the criminal law paradigm of identification of individual offenders for deterrence or retribution, these examples are limited and can be accommodated by existing criminal laws not devoted specifically to infectious disease. Third, and most importantly, the current criminal laws regarding HIV/AIDS, like many other criminal laws applied to infectious disease transmission, have been misguided in focusing on punishment of the diseased individual as a wrongful transmitter. Instead of individual offenders, activities that enhance the scale of disease transmission—behaviors that might be characterized as ‘transmission facilitation’—are a more appropriate target for the criminal law. Examples are trafficking in human beings (including sex trafficking, organ trafficking, and labor trafficking), suppression of information about the emergence of infection in circumstances in which there is a legally established obligation to disclose, and intentional or reckless activities to discourage disease treatment or prevention. Difficulties remain with justifications for criminalizing even these behaviors, however, most importantly the need for trust in reducing overall burdens of disease, problems in identifying individual responsible offenders, and potential misalignment between static criminal law and the changing nature of infectious disease.  相似文献

The purpose of this paper is to use criminological theories to explain chronic drunk driving. There is little criminological research explaining recidivist drunk driving with criminological theories. Instead, most researchers posit that repeat drunk driving is explained as a byproduct of substance abuse. Although substance abuse is likely correlated to chronic drunk driving, theoretical explanations need to go further to understand a broader set of social and psychological predictors. Factor analysis and linear regression techniques are used to estimate the relationship between items from two assessment instruments with a number of drunken driving offenses. The sample consists of nearly 3,500 individuals on probation and parole in a Southwestern state. The findings support our contention that criminological frameworks are helpful to understand chronic DUI. We found significant results for volatility, antisocial friends, teenage deviance, and negative views of the law, while controlling for age, gender, marital status, and race. DUIs are a serious problem for the criminal justice system and understanding the individual level correlates of repetitive DUI is crucial for policy development. Further, chronic DUI offers criminologists an opportunity to determine the ability of criminological theories to explain this type of behavior.  相似文献

The present study aimed to examine the difference in self-control strength between individuals with and without antisocial personality disorder (ASPD) in a Chinese male prisoner sample. Thirty-seven male inmates who met the criteria for DSM-IV ASPD and 38 who did not were asked to watch a four-minute silent videotape of an interview, and ignore the words displayed on screen during the videotape to deplete their ego strength. A handgrip task was conducted both before and after watching the videotape, with participants’ time squeezing the handgrip being the dependent variable. Result showed a significant interaction between group (ASPD/no-ASPD group) and time (baseline/post-manipulation measure). The post-manipulation result was significantly worse than the baseline result for the ASPD group, but not for the no-ASPD group. These results indicate that tasks that contribute to ego depletion lead to a deficit of self-control strength in prisoners with ASPD.  相似文献

Forensic fractographic features of bone reliably establish crack propagation in perimortem injuries. We investigated if similar fracture surface features characterize postmortem fractures. Experimentally induced peri- and postmortem fractures were used to assess if fractographic features vary as bone elasticity decreases during the postmortem interval (PMI). Thirty-seven unembalmed, defleshed human femoral shafts from males and females aged 33–81 years were fractured at varying PMIs with a drop test frame using a three-point bending setup and recorded with a high-speed camera. Vital statistics, cause of death, PMI length, temperature, humidity, collagen percentage, water loss, fracture energy, and fractography scores were recorded for each sample. Results showed that fractographic features associated with perimortem fractures were expressed in PMIs up to 40,600 accumulated degree hours (ADH), or 60 warm weather days. Hackle was the most consistently expressed feature, occurring in all fractures regardless of ADH. The most variable characteristics were wake features (78.4%) and arrest ridges (70.3%). Collagen percentage did not correlate strongly with ADH (r = −0.04, p = 0.81); however, there was a strong significant correlation between ADH and water loss (r = 0.74, p < 0.001). Multinomial logistic regression showed no association between fractographic feature expression and ADH or collagen percentage. In conclusion, forensic fractographic features reliably determine initiation and directionality of crack propagation in experimentally induced PMIs up to 40,600 ADH, demonstrating the utility of this method into the recent postmortem interval. This expression of reliable fractographic features throughout the early PMI intimates these characteristics may not be useful standalone features for discerning peri- versus postmortem fractures.  相似文献
