Network Structures: Working Differently and Changing Expectations   总被引:1,自引:0,他引:1  
There is a growing need for innovative methods of dealing with complex, social problems. New types of collaborative efforts have emerged as a result of the inability of more traditional bureaucratic hierarchical arrangements such as departmental programs to resolve these problems. Network structures are one such arrangement that is at the forefront of this movement. Although collaboration through network structures establishes an innovative response to dealing with social issues, there remains an expectation that outcomes and processes are based on traditional ways of working. It is necessary for practitioners and policy makers alike to begin to understand the realities of what can be expected from network structures in order to maximize the benefits of these unique mechanisms.  相似文献

Recent interest in migrant remittances as a development resource calls attention to a deeper issue: the relationship between migration and development. Remittances may be a significant source of economic inflows to poor countries and regions, but their actual development impact (positive or negative) is tied to the migration processes that generate them. Attention to migration in turn creates an opportunity to think about the broader context of development policy and practice, and to re-think the boundaries that we put around our work.  相似文献

Abstract:  The Direct Analysis in Real Time (DART) ion source is a relatively new mass spectrometry technique that is seeing widespread use in chemical analyses world-wide. DART studies include such diverse topics as analysis of flavors and fragrances, melamine in contaminated dog food, differentiation of writing inks, characterization of solid counterfeit drugs, and as a detector for planar chromatography. Validation of this new technique for the rapid screening of forensic evidence for drugs of abuse, utilizing the DART source coupled to an accurate mass time-of-flight mass spectrometer, was conducted. The study consisted of the determination of the lower limit of detection for the method, determination of selectivity and a comparison of this technique to established analytical protocols. Examples of DART spectra are included. The results of this study have allowed the Virginia Department of Forensic Science to incorporate this new technique into their analysis scheme for the screening of solid dosage forms of drugs of abuse.  相似文献

Little research has focused on the drugs-violence nexus in rural areas. As such, the purpose of this study is to use Goldstein's tripartite conceptual framework to examine the relationship between drugs and violence among felony probationers in rural Appalachian Kentucky (n = 799). Data on demographics, substance use criminal history, and violence were collected between 2001 and 2004 using an interviewer-administered questionnaire. Rural probationers are partitioned into four groups based on lifetime violent victimization/perpetration experiences: (a) neither a perpetrator nor a victim, (b) perpetrator only, (c) victim only, and (d) both a perpetrator and a victim. Chi-square analyses indicate substance use, and criminal history varies across the four groups. Binary logistic regression analyses are used to explore the significant correlates of both perpetration and victimization. Multivariate analyses support both the psychopharmacological model and the economic compulsive models of perpetration and victimization. Further implications of these findings are discussed.  相似文献

The purpose of this case control study was to compare police officers (n = 106) from a large urban police force, charged with committing intimate partner violence (IPV) with officers who were not charged (n = 105), in order to identify risk factors for IPV. We also compared the frequency, type, and final disposition of IPV reports filed against police officers before and after the enactment of the 1994 Violence against Women Act (VAWA). Officers accused of IPV were more likely to be members of a minority, on the force more than 7 years and assigned to a high crime district. No major differences on intake baseline MMPI scores were noted between cases and controls. A significant increase in reports of IPV was noted after the enactment of VAWA; the rate changed from 0.2/100 to 1.2/100 person years, although there were too few pre-1994 reports to compare further. Most of the final dispositions of the cases resulted in cases closed due to unsupported testimony from victims. An erratum to this article is available at .  相似文献

Reports in the literature suggest that diagnostic differences in craniofacial morphology between blacks and whites arise very early in development. These reports, however, have not been consistent regarding which traits are diagnostic and have failed to provide forensic anthropologists with a reliable method of assessment. In an effort to clarify the situation, 13 non-metric craniofacial traits were scored and analyzed statistically in a sample of 70 black and white perinatal specimens obtained from the Smithsonian's fetal osteology collection. Chi-square analysis revealed significant (p<0.05) differences in the distribution of five of the 13 non-metric traits examined. Compared with black perinates, white perinates more frequently possessed a relatively narrow supraoccipital portion of the occipital bone, a prominent anterior nasal spine, "deep" subnasal margins, an elongated vomer, and semi-circular temporal squamae. When these five traits were entered into a stepwise logistic regression, temporal squamous shape, vomer shape and subnasal margin definition were found to be predictive of race (79.1% overall correct classification). An independent sample of 39 black and white perinates was then used to validate the results; overall, 67.5% of the validation sample could be classified correctly. Reasons for the disparity in correct classification rates between the initial and follow-up sample are provided. Results of the present study may be useful for anthropologists who encounter unidentified cranial material from this age range.  相似文献
