With deinstitutionalization and community-based treatment of delinquents becoming more common, the need for facilities compatible with re-integration efforts is crucial. In line with the increasing local needs for dealing with juvenile offenders in the community, this paper advocates the use of delinquency theory as the conceptual foundation for the architectural design and placement of community-based alternatives to incarceration. In addition, we present guidelines for the site selection, community acceptance and physical design of a model community-based treatment facility for minor offenders, which are based on a theoretical integration of social control theory and the labeling approach.  相似文献

Many myths about adolescence have been refuted by research, but similar myths have grown up in recent years around emerging adulthood. This essay addresses three of those myths: the claim that they suffer from a normative “crisis”; the accusations that they are “selfish”; and their alleged reluctance to “grow up” and become adults. For each issue, evidence is presented showing that the myths exaggerate or falsify the true experience of emerging adults. Jeffrey Jensen Arnett is Research Professor in the Department of Psychology at Clark University. He is the editor of Journal of Adolescent Research and author of Emerging Adulthood: The Winding Road from the Late Teens through the Twenties (2004, Oxford University Press). He was a postdoctoral fellow under Daniel Offer at Northwestern University Medical School from 1989–1992.  相似文献

Recent work suggests that violence among people with mental illnesses is not simply due to the symptoms and comorbidities that define mental illness. We further this work by examining the extent to which strains or stressors explain the link between mental illness and violence. Specifically, we apply general strain theory (GST) to a longitudinal sample of adults with mental illnesses to investigate the lagged effects on violence of several strain measures, while controlling for mental illness symptoms, substance abuse, past violence, and other key variables. Parental drug abuse from childhood and stressful life events across the life course predict violence in adulthood. In a prospective model, relationship strain from an earlier time period significantly predicts changes in later self-reported violence. The results shed light on the ability of criminological frameworks to explain violence among people with mental illnesses.  相似文献

Young people in custodial care are known to have high levels of mental health and emotional problems, and recent policy and service developments have sought to improve their access to services. However, little is known about how they cope or about what would increase their uptake of services (when such services are available). This study aimed to develop, validate and use a standardised measure to examine the coping, help-seeking and attitudes of a larger cohort of young people in custody. There was a marked reluctance to seek help for any but the most serious of problems, but there were also indicators of what would make services more acceptable to this population, with implications for both commissioning and delivering services. In particular, greater involvement of parents and carers, offering a wider range of interventions and offering them more flexibly, and challenging stigma within the secure environment may increase uptake of services.  相似文献

We propose a typology for measuring agenda‐setting success and failure in a legislative context. Our typology goes beyond the most commonly used measure (“rolls”) and includes the full range of agenda‐setting outcomes—rolls (opposing a proposal that subsequently passes), as well as “blocks” (opposing a proposal that is subsequently defeated), “successes” (supporting a proposal that subsequently passes), and “disappointments” (supporting a proposal that is subsequently defeated)—and thus takes into account instances of both positive and negative agenda power. We discuss these measures, and the theoretical questions surrounding them, with the hope of providing some guidance to scholars of the U.S. House, as well as those analyzing agenda power in other legislatures. As a first step in this direction, we explore variation in agenda‐setting measures in 85 American state legislative chambers, the Mexican Chamber of Deputies, and the Canadian House of Commons.  相似文献

In presidential nomination campaigns, individual state primaries and a national competition take place simultaneously. The relationship between divisive state primaries and general election outcomes is substantially different in presidential campaigns than in single-state campaigns. To capture the full impact of divisiveness in presidential campaigns, one must estimate both the impact of national party division (NPD) and the impact of divisive primaries in individual states. To do so, we develop a comprehensive model of state outcomes in presidential campaigns that incorporates both state-level and national-level controls. We also examine and compare several measures of NPD and several measures of divisive state primaries found in previous research. We find that both NPD and divisive state primaries have independent and significant influence on state-level general election outcomes, with the former having a greater and more widespread impact on the national results. The findings are not artifacts of statistical techniques, timeframes or operational definitions. The results are consistent—varying very little across a wide range of methods and specifications.  相似文献

Questions of how and when managers can motivate the workforce of public organizations are fundamental for scholars and practitioners alike. A dominant assertion is that goal‐oriented leadership strategies, such as transformational leadership, foster public service motivation (PSM). However, existing studies rely on designs that are vulnerable to endogeneity and rarely investigate the scope conditions of the leadership‐PSM relationship. Combining a field experiment with 364 managers and surveys of their 3,470 employees, the authors show that transformational leadership and transactional leadership, when induced experimentally, do not have the claimed positive effect on PSM. In fact, the results indicate that goal‐oriented leadership can have demotivating effects when employee and organizational values are incongruent. Public managers should therefore carefully assess existing levels of value (in)congruence before implementing goal‐oriented leadership strategies, and—in case of value conflicts—seek to align perceptions of the desirable among members of the organization.  相似文献

Plant residue is currently an underutilized resource in forensic investigations despite the fact that many crime scenes, as well as suspects and victims, harbor plant‐derived residue that could be recovered and analyzed. Notwithstanding the considerable skill of forensic botanists, current methods of species determination could benefit from tools for DNA‐based species identification. However, DNA barcoding in plants has been hampered by sequence complications in the plant genome. Following a database search for usable barcodes, broad‐spectrum primers were designed and utilized to amplify and sequence the rbcL, trnL‐F, and rrn18 genetic loci from a variety of household plants. Once obtained, these DNA sequences were used to design species‐targeted primers that could successfully discriminate the source of plant residue from among the 21 species tested.  相似文献
