No-Fault Divorce and the Compression of Marriage Ages

We examine how no-fault divorce law affects the age at first marriage, when everyone has a different value of marriage. The heterogeneity of individual values implies an unambiguous negative effect on the variance of marriage age. We test this hypothesis with marriage records from 1970 to 1995. Controlling for state-level heterogeneity and for time trends, the standard deviation of the log age at first marriage drops by approximately 5% with the introduction of no-fault divorce. We find that the mean age at first marriage increases slightly, suggesting that the mean person is slightly worse off with no-fault divorce. (JEL K0 , D1 )     

论现代逻辑的应用

现代逻辑的价值和意义,在于其在理论上的应用。对于纯数学的基础和结构来说,现代逻辑是一种非常有用的工具,包括哥德尔不完全性定理等,都利用了现代逻辑的技术和成果。某些现代逻辑技术已经广泛应用到了工程学之中,例如,计算机工程就基于现代逻辑的高级成果。反过来,这些应用又刺激了逻辑理论本身取得更多的进步。     

MORE INFORMATIVE TESTING FOR BIVARIATE SYMMETRY

In testing for bivariate symmetry against arbitrary alternatives the well‐known test developed by Bowker in 1948 is shown to be a score test, and to have useful components. These components are asymptotically independent and asymptotically have the standard normal distribution. Moreover they assess particular pairs of cells for symmetry. These components can also be used in a data analytic manner to complement a test for bivariate symmetry against ordered alternatives.     

An Experiment in Helping Foster-Carers Manage Challenging Behaviour

A randomized controlled trial was implemented with groups offoster-carers to test the effectiveness of cognitive–behaviouralmethods in the management of difficult behaviour. Contrary toexpectations, no statistically significant differences werefound between the groups with regard to behaviour managementskills, the frequency and/or severity of behavioural problems,and placement stability. In contrast, foster-carers expressedsatisfaction with the overall training programme and increasedconfidence in dealing with difficult behaviour. Discussion ofthe results focuses on a number of competing explanations forsuch findings and concludes with recommendations for futurework.     

Are there causal relationships between the dimensions of the Maslach Burnout Inventory? A review and two longitudinal tests

Arising from interest concerning the possibility of causal relationships among the three components of the Maslach Burnout Inventory, several process models have been proposed for the development of burnout. The present paper first reviews the evidence in favour of the three most influential of these (Leiter and Maslach's model (1988); Golembiewski, Boudreau, Munzenrider, & Luo's (1996) phase model; and Lee and Ashforth's model (1993)). These three models, and our own model (which integrates of two of them, and includes feedback effects of depersonalization on emotional exhaustion) are then compared with each other using structural equation modelling, drawing on longitudinal data from two Dutch samples (total N=1185). The review revealed that none of the seven previous studies on this issue provided any convincing support for any particular causal order proposed so far. In contrast, our own study showed that high levels of exhaustion were associated with high levels of depersonalization over time across both samples. Further, higher levels of depersonalization led to higher levels of emotional exhaustion and lower levels of personal accomplishment. To our knowledge, the present research is the first to provide reliable longitudinal evidence for the conceptualization of burnout as a developmental process, although the effects are not large enough to be of practical use in the recognition of burnout.     

The future of London as an international financial centre

The success of an international financial centre depends on confidence and on occasions in the past confidence in the City of London has been undermined by the weakness of sterling, the threat of nationalization and government direction of investment of funds. Whichever government is in power, it should accept the need for international confidence and recognize the City of London for what it is, a major exporter, tax-payer and employer, which deserves as much support as any other industry.     

Career Adaptability in Childhood

Childhood marks the dawn of vocational development, involving developmental tasks, transitions, and change. Children must acquire the rudiments of career adaptability to envision a future, make educational and vocational decisions, explore self and occupations, and problem solve. The authors situate child vocational development within human life span and life course development paradigms and career development theory. They then consider the theoretical origins of career adaptability and examine it as a critical construct for construing vocational development. Two models derived from career construction theory offer guides for research and counseling practice designed to foster development through work and other social roles.     

Criteria for selecting treatment interventions with adolescents

In contrast to the current trend in clinical settings of dispensing with the diagnostic process, the view advanced in this essay is that assessment constitutes the basis for prognosis and for planning any, and all treatment interventions. The reader is offered a spectrum of treatment modalities, specifically, psychoanalysis, individual, family, group, and hospitalization. The discussion delineates the therapeutic needs in accord with the adolescent's depth of disturbance and age (e.g., early, middle, or late adolescence). Too frequently, adolescents of all ages are viewed as a homogeneous group. Individual therapy, the intervention most suitable for the largest range of adolescents, is presented in detail.is the author of several books, includingClinical Work with Children.
