Getting Unstuck: Interdisciplinarity as a New Discipline

Most disciplines and subdisciplines consider their particular specialization to be valuable in itself and superior to other disciplines. But compared with the huge leaps in the physical sciences, the social/behavioral sciences and humanities have made little progress. Since many of the physical science advances were the result of the merging of disciplines, perhaps interdisciplinarity should be tried. One path to connecting disciplines, subdisciplines, and micro‐macro levels is suggested by Spinoza's idea of part/whole methodology, exactly balancing concrete instances with abstract theses. Ideas by B. Pascal, A. Koestler, A. N. Whitehead, and E. O. Wilson may also be helpful. Any discipline, subdiscipline, or level can serve as a valuable stepping‐off place, but to advance further, integration with at least one other viewpoint may be necessary. Two brilliant examples are The Civilizing Process, by the sociologist Norbert Elias, and Freudian Repression, by the psychologist Michael Billig. Koestler's idea of “bi‐sociation” may prove to be particularly rewarding. The way that Virginia Woolf's depiction of role‐taking in interior monologue preceded the idea in social science is an extraordinary example. The need for integration may be the single most important issue facing social science, the humanities, and their subdisciplines. Given the scope of the social/behavioral problems faced by humanity, the sooner the better.     

Differences in Caregiver Self-Efficacy and Satisfaction Related to Sexual Abuse of Offspring

Research suggests parents of sexually abused children may experience negative perceptions of themselves and their parenting abilities following the victimization of their children, which may influence the recovery process in treatment for these families. This study assessed perceived self-efficacy and parenting satisfaction among female caregivers of sexually abused children and female caregivers whose children were not victimized. Results indicated that caregivers of child victims had significantly lower levels of perceived parenting efficacy than their counterparts. There were no significant differences found between groups with regard to parenting satisfaction. The results highlight the importance of evaluating perceived parenting competence in the treatment of nonoffending caregivers in order to facilitate optimal treatment of the child victim and all members of the family system.     

Production and extrapolation of meaning in the environmental justice movement

We analyze the structural determinants of social construction processes in the environmental justice movement. We argue that initial structural conditions legitimated environmental grievances that were transformed in the 1980s into a sense of environmental injustice. Environmental injustice was produced through perceptions of: the Love Canal and Three Mile Island disasters; the Reagan administration's environmental deregulation; and continuing discoveries of contaminated communities. In the extrapolation of meaning, the grievance of environmental injustice evolved into the goal of environmental justice through interaction between grassroots environmental activists and national civil rights leaders.     

Graphical contributions to the χ2statistic for two-way contingency tables

A graphical procedure for studying the cell contributions to the chi-square statistic for R×C contingency tables is presented. Several examples are included to illustrate how one might use this graphical procedure on large tables.     

On the correlation between fraud and default risk

Identity fraud is one of the fastest growing white-collar crimes today and a serious concern in our information-based economy. This paper studies one type of identity fraud: new account fraud, where an impostor opens lines of credit using a false identity, made-up or stolen. Relying on a unique data set of consumer bank accounts, that contains information on both, fraud and default losses, I analyze the correlation between fraud and default risk. I find that common socio-economic/demographic account holder characteristics have opposite effects on estimated default and fraud probabilities. For example, women possess a lower fraud probability, but a higher default probability, compared to men, and foreigners are more likely to engage in account fraud but less likely to default than Germans. Also, the portfolio level analysis indicates that portfolio loss distributions are quite sensitive to ex ante portfolio characteristics like the share of foreigners or blue-collar workers. These findings have important implications for banks managing their consumer credit portfolios using limiting rules based on borrower characteristics, and for the adequacy of banks’ capital levels.     

Estimation of Location Parameters Under Nonnormal Errors and Quadratic Loss

Assuming a statistical model in which the joint distribution of the unobservable errors is drawn from independent univariate Student t's that are identically and symmetrically distributed, the sampling performance of traditional robust estimators and a family of Stein-like estimators are compared and evaluated. These results suggest that under thick-tailed distributions, the relative sampling performances and risk characteristics for a range of nonconventional Stein estimators remains approximately the same as in the case of their normal counterparts. The empirical risk implications of misspecifying the error distribution are investigated.     

Children's Expression of Emotional Meaning in Music Through Expressive Body Movement

Recent research has demonstrated that preschool children can decode emotional meaning in expressive body movement; however, to date, no research has considered preschool children's ability to encode emotional meaning in this media. The current study investigated 4- (N = 23) and 5- (N = 24) year-old children's ability to encode the emotional meaning of an accompanying music segment by moving a teddy bear using previously modeled expressive movements to indicate one of four target emotions (happiness, sadness, anger, or fear). Adult judges visually categorized the silent videotaped expressive movement performances by children of both ages with greater than chance level accuracy. In addition, accuracy in categorizing the emotion being expressed varied as a function of age of child and emotion. A subsequent cue analysis revealed that children as young as 4 years old were systematically varying their expressive movements with respect to force, rotation, shifts in movement pattern, tempo, and upward movement in the process of emotional communication. The theoretical significance of such encoding ability is discussed with respect to children's nonverbal skills and the communication of emotion.     

Age structure effects and growth in the OECD, 1950–1990

Economic growth depends on human resources and human needs. The demographic age structure shapes both of these factors. We study five-year data from the OECD countries 1950–1990 in the framework of an age structure augmented neoclassical growth model with gradual technical adjustment. The model performs well in both pooled and panel estimations. The growth patterns of GDP per worker (labor productivity) in the OECD countries are to a large extent explained by age structure changes. The 50–64 age group has a positive influence, and the group above 65 contributes negatively, while younger age groups have ambiguous effects. However, the mechanism behind these age effects is not yet resolved. Received: 16 January 1997/Accepted: 2 July 1998
