Effects of Spousal Economic and Cultural Factors on Dutch Marital Satisfaction

Using panel data of Dutch first marriages with children (N _{Time 1}=646, N _{Time 2}=386), the relevance of economic and cultural factors in understanding marital satisfaction is examined. The sample was middle-aged and the average marital duration was 17 years (at Time 1). Besides, couples mainly represent single earner and main-earner households. Our results demonstrate that both economic and cultural factors are valid in understanding marital satisfaction. However, whereas cultural characteristics are more important explaining spousal marital satisfaction at Time 1, economic indicators are important predicting change in marital satisfaction. An interaction effect between cultural and economic factors was found as well. Husbands’ familialism moderates the effect of women’s employment on women’s marital satisfaction at Time 1.Ann Van den Troost, Center for Population and Family Research, Department of Sociology, Catholic University of Leuven, Van Evenstraat 2B, 3000 Leuven, Belgium; e-mail: ann.vandentroost@soc.kuleuven.ac.beAd A.

Administrative structure theory and evaluation: An example from the Community Services Administration

Concern about the inability of existing theories of utilization to explain the use (or lack thereof) of evaluation research on policymaking in public agencies leads the authors to postulate an “administrative structure theory.” Utilization is then explained, in large part, by the structure and behavior of administrative agencies. Administrative structure theory rests on four propositions which relate evaluation research to the development and maintenance sub-systems (within the administrative structure). These propositions are illustrated in the context of the recently abolished U.S. Community Services Administration.     

Going social: Championing a holistic model of mental distress within professional education

Within the context of current debates as to how to raise the profile of social perspectives within mental health social work education, this paper seeks to assemble various elements that might belong within a social (or psychosocial) model of mental health practice. A clarification of what may actually be meant by a social model would be helpful in starting to set the parameters of future social work curricula, both at qualification and post-qualification levels, in terms of an appropriate value base and theoretical orientation. This may be seen to be important if social workers are to be properly prepared for taking on some form of leadership around the promotion of social approaches within the practice of multi-disciplinary teams.     

Leisure activity and adjustment in retirement

A sample of retired persons in a southern metropolitan area responded to a questionnaire designed to investigate the interrelationship between level of leisure activity and adjustment in retirement Adjustment was measured by two indices, life satisfaction and alienation. The survey's results show that persons who have more leisure activities are more satisfied with their lives and are less alienated than those who have few leisure activities.     

The Impact of Logistics Performance on Trade

This paper studies the impact of logistics performance on global bilateral trade. Taking a supply chain perspective, logistics performance refers to cost, time, and complexity in accomplishing import and export activities. We draw on a data set compiled by the World Bank containing specific quantitative metrics of logistics performance in terms of time, cost, and variability in time. Numerous researchers have shown that logistics performance is statistically significantly related to the volume of bilateral trade. Our research calibrates the impact of specific improvements in logistics performance (time, cost, and reliability) on increased trade. Our findings can spur public and private agencies that have direct or indirect influence over logistics performance to focus attention on altering the most relevant aspects of logistics performance to improve their country's ability to compete in today's global economy. Moreover, as our logistics metrics are directly related to operational performance, countries can use these metrics to target actions to improve logistics and monitor their progress.     

A DIRICHLET PROCESS MIXTURE OF HIDDEN MARKOV MODELS FOR PROTEIN STRUCTURE PREDICTION

By providing new insights into the distribution of a protein's torsion angles, recent statistical models for this data have pointed the way to more efficient methods for protein structure prediction. Most current approaches have concentrated on bivariate models at a single sequence position. There is, however, considerable value in simultaneously modeling angle pairs at multiple sequence positions in a protein. One area of application for such models is in structure prediction for the highly variable loop and turn regions. Such modeling is difficult due to the fact that the number of known protein structures available to estimate these torsion angle distributions is typically small. Furthermore, the data is "sparse" in that not all proteins have angle pairs at each sequence position. We propose a new semiparametric model for the joint distributions of angle pairs at multiple sequence positions. Our model accommodates sparse data by leveraging known information about the behavior of protein secondary structure. We demonstrate our technique by predicting the torsion angles in a loop from the globin fold family. Our results show that a template-based approach can now be successfully extended to modeling the notoriously difficult loop and turn regions.
