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

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

The real interest rate is a very important variable in the transmission of monetary policy. It features in vast majority of financial and macroeconomic models. Though the theoretical importance of the real interest rate has generated a sizable literature that examines its long-run properties, surprisingly, there does not exist any study that delves into this issue for South Africa. Given this, using quarterly data (1960:Q2-2010:Q4) for South Africa, our paper endeavors to analyze the long-run properties of the ex post real rate by using tests of unit root, cointegration, fractional integration and structural breaks. In addition, we also analyze whether monetary shocks contribute to fluctuations in the real interest rate based on test of structural breaks of the rate of inflation, as well as, Bayesian change point analysis. Based on the tests conducted, we conclude that the South African EPPR can be best viewed as a very persistent but ultimately mean-reverting process. Also, the persistence in the real interest rate can be tentatively considered as a monetary phenomenon. 相似文献

Purpose
Measures of adolescent psychopathy have yet to be examined in offending trajectory studies. This may explain why identifying etiological differences between individuals following high-rate and moderate-rate offending trajectories has remained elusive. The current study used the Psychopathy Checklist: Youth Version (PCL:YV) to examine psychopathic traits and offending trajectories within a sample of incarcerated offenders.Methods
Convictions were measured for Canadian male (n = 243) and female (n = 64) offenders at each year between ages 12 and 28. Semi-parametric group based modeling identified four unique trajectories: adolescence-limited (AL) (27.3% of sample), explosive-onset fast desister (EOFD) (30.6%), high-rate slow desister (HRSD) (14.6%), and high frequency chronic (HFC) (27.5%).Findings
Both a three and a four factor model of psychopathy were tested, and both factor structures were positively and significantly associated with the HRSD and HFC trajectories. Regarding individual factors of psychopathy, the ‘Antisocial’ factor of the PCL:YV was the only individual dimension significantly associated with membership in high-rate compared to moderate-rate offending trajectories.Conclusions
Psychopathic traits appear more commonly present amongst individuals who follow chronic versus moderate offending trajectories. Implications for early intervention and risk management of offenders are discussed. 相似文献917.
Purpose
To examine the persistence of physical aggression in preschoolers and associated correlates (i.e., socio-demographic, socioeconomic, criminality, parenting practices, maternal mental health).Methods
One-year follow-ups are completed with 240 mothers and their preschool children (boys and girls) from the Vancouver Longitudinal Study on the Psychosocial Development of Children. A series of structural equation models are examined.Results
Maternal psychological symptoms, juvenile delinquency, and adult offending are associated with higher levels of physical aggression in their offspring. Children of non-Caucasian mothers and those born outside of North are less physically aggressive. Cultural differences in the correlates of physical aggression were identified.Conclusions
Maternal past delinquency, current adult offending, and mental health are important factors in the development of children’s physical aggression. The findings suggest that there are multiple pathways leading to chronic physical aggression, which may be culturally-based. Cultural differences should be taken into account when developing programs and intervening with families of children with behavioral problems. 相似文献918.

Political science generally treats identities such as ethnicity, religion, and sexuality as “unmoved movers” in the chain of causality. I hypothesize that the growing salience of partisanship and ideology as social identities in the United States, combined with the increasing demographic distinctiveness of the nation's two political coalitions, is leading some Americans to engage in a self-categorization and depersonalization process in which they shift their identities toward the demographic prototypes of their political groups. Analyses of a representative panel data set that tracks identities and political affiliations over a 4-year span confirm that small but significant shares of Americans engage in identity switching regarding ethnicity, religion, sexual orientation, and class that is predicted by partisanship and ideology in their pasts, bringing their identities into alignment with their politics. These findings enrich and complicate our understanding of the relationship between identity and politics and suggest caution in treating identities as unchanging phenomena. 相似文献
