Peer victimization is a common problem among adolescents that has been linked to a variety of adjustment problems. Youth involved in peer victimization represent a heterogeneous group who may differ not only in their levels of victimization and perpetration, but also in the factors that influence their behavior. The current study used latent class analysis (LCA) to identify subgroups of aggressive and victimized youth, and to examine social-cognitive and environmental factors that differ across these subgroups. Participants were a predominantly African-American (i.e., 68 %) sample of 502 sixth, seventh, and eighth graders (45 % male, Mean age = 12.6 years) attending three urban public middle schools, who completed self-report measures of aggression, victimization, and associated individual and contextual factors. LCA identified four classes of adolescents representing non-victimized aggressors, aggressive-victims, predominantly victimized youth, and well-adjusted youth. Class differences were found on measures of beliefs supporting fighting, beliefs against fighting, perceived effectiveness of inept nonviolent responses to conflict, behavioral intentions to engage in aggressive and nonviolent behavior, self-efficacy for nonviolent behavior, and peer and parental support for aggression and nonviolence. For example, within the two classes of victimized youth, aggressive-victims reported greater intentions to engage in physical aggression and inept nonviolent behavior, and were more likely to agree with beliefs supporting the use of instrumental and reactive aggression, and beliefs that fighting is sometimes necessary compared to predominantly victimized youth. These findings emphasize the importance of developing preventive interventions that target the specific needs of distinct subgroups of adolescents. 相似文献

Policy research has become an integral part of the policymaking process but is changing as the goals and emphases o f policies change. The paper explores the shift in emphasis in evaluation research away from predominantly programmatic concerns and toward accountability issues in personnel and job evaluation. It depicts an inward turning in domestic policies from the provision of services to evaluation of government itself, and an acceleration in conflict over how the work of government should be structured and performed, and by whom. Using examples from three levels o f government, it describes what makes policies controversial, their evaluations political, and how the search for legitimacy and legitimizing technologies raises the stakes for all actors in the policy process–elected officials, administrators, consumers, and evaluators. Conclusions are drawn regarding the effect on research o f these changes in policy. 相似文献

In response to Nagin's comment on our paper, Methodological Sensitivities to Latent Class Analysis of Long-Term Criminal Trajectories, we reconsider the robustness and validity of group-based approaches to criminal trajectories and introduce additional issues for future research. We emphasize the limitations of typological approaches and the dangers of reifying the idea of distinct offender groupings for research and policy. We also clarify misunderstandings about the use of hierarchical linear models for studying trajectories of crime. Our basic conclusion is that methods in criminology need to be more tightly linked with theory. 相似文献

The Y-PLEX 12 system, developed for use in human identification, enables simultaneous amplification of eleven polymorphic short tandem repeat (STR) loci, namely DYS392, DYS390, DYS385 a/b, DYS393, DYS389I, DYS391, DYS389II, DYS 19, DYS439 and DYS438, residing on the Y chromosome and Amelogenin. Amelogenin provides results for gender identification and serves as internal control for PCR. The validation studies were performed according to the DNA Advisory Board's (DAB) Quality Assurance Standards. The minimal sensitivity of the Y-PLEX 12 system was 0.1 ng of male DNA. The mean stutter values ranged between 3.76-15.72%. A full male profile was observed in mixture samples containing 0.5 ng of male DNA and up to 400 ng of female DNA. Amelogenin did not adversely affect the amplification of Y-STRs in mixture samples containing male and female DNA. The primers for the Y-STR loci present in Y-PLEX 12 are specific for human DNA and some higher primates. None of the primate samples tested provided a complete profile at all 11 Y-STR loci amplified with the Y-PLEX 12 system. Y-PLEX 12 is a sensitive, valid, reliable, and robust multiplex system for forensic analysis, and it can be used in human forensic and male lineage identification cases. 相似文献

Political mechanisms of accountability were marginalized by Conservative government reforms during the 1980s and 1990s which sought a more market-oriented approach within the public sector in order to enhance ‘consumerism’. In education, parents were given more choice between schools and were provided with more information on school performance. The promotion of market accountability has involved a reduction in the powers of local education authorities (LEAs) which had been central to the operation of political accountability. However, whilst market-based forms of accountability were firmly enhanced in principle by the legislation, to what extent have the forms of accountability operating within LEAs changed in practice? Interviews with Chief Officers and the Chair of the Education Committee are used to identify changing perceptions and practices of accountability in LEAs in Wales. The findings indicate that although local politicians and officials have been forced to operate within the legislative framework of market accountability, they have sought to impede its successful implementation. The policy community in Wales facilitated the LEAs’ capacity to respond in this way. The market-based reforms conflicted with fundamental values held in Wales, which remain those of professional accountability. 相似文献

This paper examines the noncustodial parent earned income tax credit (NCP EITC), a new type of credit recently enacted in New York and Washington, D.C., and proposed by Senator Bayh and then‐Senator Obama in 2007. The NCP EITC offers an earned income tax credit to low‐income noncustodial parents who work and pay their full child support. This paper provides background information about the policy and presents national estimates of eligibility and benefits for an NCP EITC under three alternative policy scenarios. It also discusses several key design and implementation issues. © 2010 by the Association for Public Policy Analysis and Management. 相似文献

Research into community corrections officers’ perceptions of the needs of ex-offenders has largely been overlooked. While
some empirical research has emerged regarding federal parole officers’ perceptions, it is conceptually incomplete. A gap in
the literature remains regarding the concordance or discordance between offenders and community corrections officers’ perceptions
of offender needs and the opportunities for success upon release. Using a sample of community corrections officers in Seattle,
Washington, this research examined officer perception of ex-offender needs, the value officers’ placed on the specific needs,
and the opportunities available for offenders to meet their needs. Differences between officers emerged including the finding
that female officers rated needs and challenges for offenders significantly different than male officers. Policy implications
of the research are discussed.
This research was made possible due to a grant award from the College of Arts and Sciences at Seattle University. This research
was first presented at the 2005 Academy of Criminal Justice Sciences Conference in Chicago. We are grateful to Mac Pevey and
Keven Bovenkamp from the Washington State Department of Corrections and Bill Corn and Tim McTighe from United States Probation
and Pretrial Services for their support, assistance, and for making the study possible. A special thanks to our research assistant
Tania Reyes who was instrumental in collecting the data for this investigation. 相似文献

“Business development” is a corporate entrepreneurial capability (or competence) that has emerged in the Information Technology
industry to support that industry’s practice of co-creation of value with customers and complementors. As a set of practices
that link the firm’s value creating processes with its external environment, business development capabilities are a key factor
in the success of IT SMEs. This article examines business development functions and business developer attributes in SMEs
in the Information Technology Industry in Eastern Canada. The principal business development functions are finding profitable
opportunities in business networks, developing and maintaining partnerships, providing support for new product development,
and recognizing and responding to customer needs. The regional market and export markets require different business development
capabilities. 相似文献
