Using a sample of 1,130 male juvenile offenders, the relationship of four types of ‘broken home’ to the age at onset of delinquency, recidivism, rate of offences, and types of offence was investigated. The number of recidivists was found to be significantly greater among offenders who were living only with fathers than among offenders living with both parents. A trend in this direction was also found among offenders living only with mothers. Offenders living apart from parents were found to be older at the time of their first offence than were offenders living with both parents. The findings were discussed critically, and it was concluded that they support the hypothesis that the ‘broken home’ is not per se a causal factor in juvenile delinquency.  相似文献

The classification of clients in terms of psychiatric diagnosis or level of functioning is a logical prerequisite to the conduct of quality of care assessments in mental health care. This article reports on efforts to create a typology of mentally ill group home residents based on a variety of measures of functioning. Subjects for the study come from a probability sample of 253 group home residents in Michigan. A three group typology, derived through cluster analytic procedures, is presented along with-evidence supporting its validity. Implications of the typology for program evaluators and service system planners are briefly addressed.  相似文献

This commentary is structured around two different definitions for the concept of relativism. The contention is that a great deal depends on the particular interpretation one gives to this concept — not only for understanding the particular positions elaborated in these papers, but also for a general understanding of the issue of justifying conclusions in evaluations.  相似文献

After the 9/11 terrorist attacks, the U.S. government initiated several national security technology adoption programs. The American public, however, has been skeptical about these initiatives and adoption of national security technologies has been mandated, rather than voluntary. We propose and test a voluntary behavioral intention formation model for the adoption of one type of new security technology: portable radiation detectors. Portable radiation detectors are an efficient way of detecting radiological and nuclear threats and could potentially prevent loss of life and damage to individuals’ health. However, their functioning requires that a critical mass of individuals use them on a daily basis. We combine the explanatory advantages of diffusion of innovation with the predictive power of two volitional behavior frameworks: the theory of reasoned action and the health belief model. A large sample survey (N = 1,482) investigated the influence of factors identified in previous diffusion of innovation research on portable radiation detector adoption intention. Results indicated that nonfinancial incentives, as opposed to financial incentives, should be emphasized in persuasive communications aimed at fostering adoption. The research provides a new integration of diffusion of innovation elements with determinants of volitional behavior from persuasion literature, and offers recommendations on effective communication about new security technologies to motivate public adoption and enhance national safety.  相似文献

From an international perspective, Australia has been one of the leading jurisdictions for corporate governance reform. Its first corporate governance code predates the Cadbury Report, and Australia is also one of the few countries internationally to have been only marginally affected by the recession that ensued after the Global Financial Crisis. Considerable governance reform has occurred since 2007–8 in Australia, however; much of it occasioned by pressure brought to bear by institutional investors as a reaction to both traditional governance failings and also social and environmental concerns such as a growing awareness of climate change. Institutional influence is primarily associated with the compulsory retirement income system that emerged in the 1980s in light of an economy‐wide union campaign. While governance structures are becoming more homogenous, institutional logics reflecting trustees’ concerns are driving and shaping this ongoing process. A new approach to corporate engagement has emerged under the influence of investor representative bodies such as the Australian Council of Superannuation Investors that is driving corporate governance change.  相似文献

This study examined the impact of risk factors, self and peers’ beliefs, and parental communication on condom use among 290 female adolescents who attended family planning clinics. The major findings showed that in addition to risk factors, self and peer beliefs about condom use and parental communication about birth control predicted actual condom use. Implications for social workers about the importance of encouraging communication between adolescents and their parents are discussed.  相似文献
