Are politically decentralized states better at fostering long‐run technological innovation than centralized states? Societies with decentralized governments are widely seen as agile, competitive, and well structured to adapt to innovation's gale of creative destruction. Meanwhile, centralized states, even when democratic, have come to be viewed as rigid and thus hostile to the risks, costs, and change associated with new technology, or prone to cling too long to foolhardy or outdated technological projects. Therefore government decentralization is often perceived as a necessary institutional foundation for encouraging long‐run technological innovation. However, in this article, I analyze data on international patent activity, scientific publications, and high‐technology exports, and show that there exists little evidence for an aggregate relationship between government structure and technological innovation. 相似文献

Labeling effects of initial juvenile justice system processing decision on youth interpersonal ties*
Zachary R. Rowan Adam Fine Laurence Steinberg Paul J. Frick Elizabeth Cauffman 《犯罪学》2023,61(4):731-757
The juvenile justice system can process youth in myriad ways. Youth who are formally processed, relative to being informally processed, may experience more public and harsh sanctions that label youth more negatively as “deviant.” Drawing on labeling theory, the current study evaluates the relative effect of formal justice system processing on the interpersonal dynamics of youth peer networks. Using data from the Crossroads Study, a multisite longitudinal sample of first-time adolescent offenders, the current study applies augmented inverse probability weighting and generalized mixed-effects models to estimate the effects of formal processing on friendship selection processes of homophily and withdrawal and considers whether these effects vary by race and ethnicity. Consistent with expectations of homophily, formally processed youth acquire more new deviant peers and fewer nondeviant peers during the 3 years after their initial processing decision compared with informally processed youth. The findings suggest no differences exist across processing types in withdrawal from friends. These effects were consistent across racial and ethnic groups. Ultimately, this study explores the dynamic interpersonal mechanisms associated with labeling theory and offers additional insight into the negative effects of formal processing. 相似文献

Objectives
The purpose of the present meta-analysis was to answer the question: Can the Andrews principles of risk, needs, and responsivity, originally developed for programs that treat offenders, be extended to programs that treat drug abusers?Methods
Drawing from a dataset that included 243 independent comparisons, we conducted random-effects meta-regression and ANOVA-analog meta-analyses to test the Andrews principles by averaging crime and drug use outcomes over a diverse set of programs for drug abuse problems.Results
For crime outcomes, in the meta-regressions, the point estimates for each of the principles were substantial, consistent with previous studies of the Andrews principles. There was also a substantial point estimate for programs exhibiting a greater number of the principles. However, almost all the 95 % confidence intervals included the zero point. For drug use outcomes, in the meta-regressions, the point estimates for each of the principles was approximately zero; however, the point estimate for programs exhibiting a greater number of the principles was somewhat positive. All the estimates for the drug use principles had confidence intervals that included the zero point.Conclusions
This study supports previous findings from primary research studies targeting the Andrews principles that those principles are effective in reducing crime outcomes, here in meta-analytic research focused on drug treatment programs. By contrast, programs that follow the principles appear to have very little effect on drug use outcomes. Primary research studies that experimentally test the Andrews principles in drug treatment programs are recommended. 相似文献47.
The Differentiation of Menstrual from Venous Blood and Other Body Fluids on Various Substrates Using ATR FT‐IR Spectroscopy

Crime scene investigators and laboratory analysts use chemical tests to detect and differentiate body fluids. Testing often requires a sample of the stain, and the chemicals may cause degradation of the fluid or interfere with subsequent tests. Colorimetric chemical tests do not differentiate between different types of the same fluid, such as venous and menstrual blood, and there is no presumptive test available to simultaneously differentiate several body fluids. In this study, we recorded ATR FT ‐IR spectra of venous and menstrual blood, semen, saliva, and breastmilk. Neat and simulated casework body fluid samples were analyzed on cotton, nylon, wood, paper, and glass substrates. Differences in fluid composition, including proteins and small molecules, resulted in spectral differences. Venous and menstrual blood is differentiated by the peak at 1039 cm?1 attributed to phosphoric acid found in menstrual blood. Peak intensity is influenced by the porosity and weave of the substrate fabric. 相似文献

This study examined how personal and workplace variables were related to organizational commitment among staff working at a large Southern prison. The personal variables were gender, age, position, tenure, educational level, and supervisory status. The workplace variables were assessment of training, job variety, role clarity, input into decision-making, and instrumental communication. The results indicate workplace variables play a greater role in shaping affective commitment of surveyed Southern prison staff than do personal variables. The personal variables explained only 10% of the variance in the commitment index, while workplace factors accounted for approximately 59% of the variance and were significant determinants of organizational commitment among the respondents. In the multivariate regression analysis, age, assessment of training, job variety, role clarity, input into decision-making, and instrumental communication all had positive associations with commitment. Educational level had a negative relationship with commitment. Implications of these findings for policy and future research are also discussed. 相似文献

Sexual abuse of males is common. While a wide body of literature examines the behavioral, emotional, and social consequences associated with being sexually abused, comparatively few studies have focused on males. This study addresses this gap by examining the influence of family and peer context on long-term behavioral outcomes in a nationally representative, longitudinal, multi-informant sample of sexually abused boys 5 years after initial involvement in the child welfare system (N = 171). Cumulative family risk conferred greater risk for internalizing and externalizing problems over time while social skills had a buffering effect. Peer rejection had a more prominent role in influencing internalizing outcomes; however, this influence did not extend to externalizing problems. These findings lend support to the growing body of research underscoring the dynamic and complex relationship between behavioral problems across development. As prevention and intervention efforts for males are developed, it is critical to consider sexual abuse victimization and the multi-systemic risk and resilience processes. 相似文献
