Determinants of Portfolio Efficiency Losses in US Self-directed Pension Accounts

This empirical study evaluates the magnitude of efficiency losses of household portfolio choices in self-directed pension accounts (SDAs). It uses data from the Survey of Consumer Finances (SCF). The determinants of the magnitude of efficiency losses across household investors are investigated in detail. The findings of this study lend empirical support to the belief that the magnitude of efficiency losses for household investors differs with the different demographic characteristics and investment propensities. In particular, household investors with long-investment horizons, with more autonomy of choices in their SDAs, or with the tendency to select high levels of portfolio risk in SDAs are more vulnerable to efficiency losses. Factors to predict the levels of portfolio risk maintained by household investors in their SDAs are also explored.     

A constructivist approach to the help-seeking process of clients: A response to cultural diversity

The issue of cultural diversity presents clinicians with both delemmas and opportunities. To deal with such a challenge, I have proposed a constructivist approach to the help-seeking process of clients from diverse ethnoracial backgrounds. A model of clients' help-seeking processes provides a useful and systematic frame for clinicians to understand clients' construction of their problem situations and possible solutions. It provides a useful key for clinicians non-presumptuously to understand clients' subjective experiences, and to enhance clients' ability to resolve problems.     

Voluntarism, self-help and rural community development: Some current approaches

Within the last decade or so, there has developed an increased concern for the welfare of rural communities and for individuals within such communities. At the same time there has emerged a parallel concern for environmental matters, concerned with conservation of species and habitat and the protection of cherished landscapes and amenities. Both sectors of rural concern have been characterised by debate about the means of delivery of policies and programmes in their respective areas and, in particular, about the balance between state action and the activities of the private sector. A common thread running through such debates has been the role of what is loosely called the ‘voluntary sector’, that is the complicated mix of individuals and organisations, local and national, which involve themselves in effort, not for direct payment nor as a routine of work, but because of feelings of commitment, belief and ideology.This paper is concerned with just one aspect of this sector — that which involves social and community aspects of the lives of rural dwellers in the English countryside. Despite this restricted field, there is an attempt to see things within a broader socio-political context, such that rural voluntarism and rural self-help can be assessed not only against a wider picture of volunteering generally but also placed within a political framework, both national and local. Voluntarism and self-help cannot exist independently of the world around them, yet the very process of facing up to the wider political realities creates problems of accountability and control to the extent that some would dismiss the voluntary sector as ineffective at best or the tool of vested interests at worst.     

The cyclical pattern of child physical abuse from a psychoanalytic self-psychology perspective

Child physical abuse is a problem that moves from generation to generation. As yet, there has been no adequate theoretical conceptualization for this phenomenon. This article examines the multigenerational dimension of child abuse from the developmental perspective of psychoanalytic self-psychology. The research data available on the role of empathy in child abuse is integrated into the discussion and applied to the empirical basis of the self-psychology paradigm. Finally, the use of empathy in this theoretical model is applied to a discussion of intervention strategies in a number of treatment modalities.     

Distribution of the cross-correlations of squared residuals in ARIMA models

ABSTRACT The distribution of the cross-correlations of squared residuals from Box-Jenkins models is considered in very general conditions, and the asymptotic distribution is derived. A test for a lagged relationship in volatility for economic time series under instantaneous causality is proposed, and its empirical behaviour is studied. An example involving the international stock market's volatility is studied, and an interesting result is observed.     

Nonparametric regression estimation at design poles and zeros

ABSTRACT In most treatments of nonparametric regression, it is assumed that the marginal density of the explanatory variables is strictly bounded away from zero and infinity. This note investigates the pointwise asymptotics for nonparametric regression when this assumption fails, that is, the marginal density of the explanatory variable has either an isolated zero or a pole at the point of interest.     

History of sexual abuse and parental alcohol misuse: Risk,outcomes and protective factors in adolescents

This study examined the school performance, suicidal involvement, disordered eating behaviors, pregnancy risk and chemical use of teenagers with a history of sexual abuse or parental alcohol misuse and found that they had higher rates of these adverse outcomes than among a comparison group of teenagers without such background risk factors. Adolescents with dual-risk background reported higher levels of suicide risk, disordered eating, sexual behaviors and chemical abuse than teenagers with only one background risk factor. Among index group members, protective factors against these adverse outcomes included a high degree of religiosity and the ability to discuss problems with family or friends. Risk factors that increased the likelihood of adverse outcomes included depression, perceived substance use in school and worries about family financial security.The first author was supported in the preparation of this article by a grant from the Lois and Samuel Silberman Fund of New York.
