Employment theoretically serves as a source of informal social control that can promote desistance from crime (Sampson & Laub, 1993). Findings from studies assessing the effects of employment, however, have been mixed. In a seminal study, Uggen (2000) reanalyzed data from the National Supported Work (NSW) Demonstration Project and found that employment significantly reduced the rate of recidivism among individuals aged 27 and older but had no impact on younger individuals. We reproduce and replicate Uggen's (2000) findings with data from four distinct employment programs: The National Supported Work Program (1975–1979), the Transitional Aid Research Project (1976–1977), the Employment Services for Ex-Offenders (1981–1984), and the Enhanced Services for the Hard-to-Employ Center for Employment Opportunities (2004–2008). We closely reproduced Uggen's original findings in the NSW but found evidence that the statistically significant interaction between age and employment in the NSW was only present at the year 3 follow-up and the observed effect is highly sensitive to minor threats to internal validity. Furthermore, a significant age–employment interaction was not observed in the three other data sources. These findings should encourage scholars to continue to investigate the age-graded nature of employment and crime, especially through a sociohistorical lens.  相似文献

Drawing on the psychological principle that proximal consequences influence behavior more strongly than distal consequences, the authors tested the hypothesis that criminal suspects exhibit a short-sightedness during police interrogation that increases their risk for confession. Consistent with this hypothesis, Experiment 1 showed that participants (N = 81) altered how frequently they admitted to criminal and unethical behaviors during an interview to avoid a proximal consequence even though doing so increased their risk of incurring a distal consequence. Experiment 2 (N = 143) yielded the same pattern, but with a procedure that reversed the order of the proximal and distal consequences, thereby ruling out the possibility that it was the unique characteristics of the consequences rather than their proximity that influenced the admission rate. The authors discuss the supported psychological process as a potential explanation for several well-established findings reported in the literature on confessions.  相似文献

Each year, the United States invests about $45 billion in research conducted by federal researchers within federal laboratories. These efforts generate extensive social benefits when results are transferred to the private sector. It is important that we effectively quantify the economic and societal impact of federal technology transfer activities to inform taxpayers and policymakers about the value of public investments in this form of research. The Argus II device, an artificial retina commercialized in the United States by Second Sight in 2013, provides a rich example of how private sector innovation can be enhanced by research collaborations with federal labs and academia. Over the 25-year journey from idea to product, Second Sight carried out research and development collaborations with six Department of Energy national laboratories and seven universities. The case of Argus II also offers valuable insight into (1) how private industry, academia, and government can work together to bring socially beneficial innovations to fruition and (2) the tradeoffs inherent in these public–private collaborations. In this paper, we use a Markov model to estimate the realized and potential future social benefits associated with Argus II. We provide an interactive tool that can be used to replicate our findings and modify assumptions using updated patient information as it becomes available. We also provide insight into the aspects of federal involvement surrounding the development of Argus II that contributed to its successful commercialization and discuss other spillover benefits from these public–private collaborations.  相似文献

Public and private sector portfolio managers pursue similar goals even though they perform their portfolio management responsibilities in significantly different environments. This article compares and contrasts corporate cash management with state government practices. The comparison and analyses are based on data drawn from a survey of state government portfolio managers and an earlier study which reviewed corporate cash management practice.
The comparison and analyses consider investment objectives, permissible assets, assets held, and asset holding period, among other factors. The results suggest that portfolio management practices are quite similar even though the cash management environment is significantly different.  相似文献

Laub and Sampson (2003) and Paternoster and Bushway (2009) offered opposing explanations of desistance from crime. Yet, extant research has failed to test the key theoretical differences that distinguish these perspectives: 1) the temporal ordering of internal changes in identity/values and life transitions and 2) the impact of values/life transitions on offending conditional on key predictors from the opposing theory (e.g., whether marriage contributes to desistance among individuals who already hold prosocial values). We assess competing claims using data from the Pathways to Desistance. We find that within-person changes in prosocial value orientations are significantly related to within-person changes in one's likelihood of entering into serious romantic relationships and becoming employed. Conversely, life transitions are unrelated to changes in one's values. The results derived from fixed-effects Poisson models indicate high or increasing prosocial value orientations help explain offending patterns among those who enter into serious romantic relationships/get employed and help explain changes in offending among those who do not experience structural “turning points.” Marriage/cohabitation is unrelated to within-person changes in offending, whereas the impact of employment has an inconsistent relationship. Theoretical and policy implications are discussed.  相似文献

This paper develops a formal model exploring how declining states allocate scarce military resources across multiple commitments under uncertainty. The model reveals that under certain conditions, states might actually benefit from their own uncertainty. In the model, a declining state’s uncertainty creates incentives for a revisionist rising power to misrepresent its intentions. But importantly, this misrepresentation requires the rising state to act cooperatively, implementing policies that immediately benefit the declining state. The model reveals how declining states can exploit these incentives in order to maximize the short-term benefits of their counterpart’s cooperation. Under some conditions, the benefits of this deceptive cooperation can outweigh the long-term costs of being deceived. These dynamics do not operate when the declining state is certain of the rising state’s type. I illustrate this logic through a case study of Great Britain’s pre-WWI naval withdrawal from East Asia.  相似文献

In prior tests of Beckerian rational choice theory, the notion that individuals are responsive to the (dis)incentives associated with crime has been supported. Much of this research has comprised composite scores of perceived rewards and risks of multiple, often disparate, crime types that are then used to predict “general” offending behavior. Although the results of such prior tests are informative, we believe that this tendency has resulted in two shortcomings. First, a central component of mathematical rational choice theory is overlooked, namely, that responsivity to incentives will be crime specific. That is, offenders should prefer crime types that subjectively offer greater rewards and fewer risks relative to other crimes. Second, individual differences in offending specialization are not addressed, of which Clarke and Cornish (1985) and Shover (1996) argued rational choice theories are well suited to explain. Using a sample of serious offenders, we find that in a given time period, individuals are more likely to engage in crime types they viewed as more intrinsically rewarding and less risky compared with other crimes. Furthermore, individuals displayed greater specialization in violence to the extent they view violence as more rewarding and less risky than property offenses  相似文献
