Analyzing migration decisions: the first step-whose decisions?

Many theories of geographic mobility assume that the change-of-residence process includes a substantial degree of choice. This paper classifies stated reasons for moving from the 1973 through 1977 Annual Housing Survey into forced, imposed, and preference-dominated categories. About 25 percent of residential mobility and 40 percent of migration occurred under conditions of substantial constraint. Mobility was most often constrained by family dynamics; for migration, occupational relocations frequently imposed the decision-to-move process and determined destinations. The volume of constrained movement indicates that its impact upon individuals, population dynamics, and voluntaristic theories of mobility deserves greater consideration.     

Karen Horney (1885–1952) A Tribute

It is twenty-five years since the passing of Karen Horney. A productive professional who dared to differ with Sigmund Freud, Horney has written clearly and brilliantly, almost in a "common-sensical" style, about the development of neurotic character structure and interpersonal relationships. Her stress on cultural, societal, and family influences has strong implications for theorists and professional practitioners in the field of marriage and the family. Her optimistic view of human nature, especially as it relates to the possibility for change at all ages and stages, should be a continuous inspiration to those helping disturbed individuals, relationships, marriages, and families. This is a tribute to a rare, worthy human being.     

An application of multiple objective linear programming to media selection

A multiple objective linear programming (MOLP) method utilizing interval criterion weights is applied to the problem of media selection. Using this technique, it is possible to analyze a problem more explicitly in terms of the several objectives inherent in many media selection situations. In order to illustrate the interval criterion weights approach, a multiple objective hierarchical media selection model is presented and its computer results discussed. In addition to being able to deal more directly with different decision criteria, a distinguishing feature of the mathematical analysis applied here is that its output enables the media-planner to be presented with a small cluster of candidate media schedules (rather than just one). Then, from this list, the media-planner should be in a position to qualitatively make a final choice as a close approximation to his optimal solution.     

Business drivers not sector membership determine the most effective production planning and control; a novel approach to a perennial problem

This paper outlines research aimed at developing novel planning and scheduling reference models for industrial sectors where the MRPII paradigm is not appropriate. It outlines the process mapping approach adopted, the data capture method developed for the case study companies, the use of ARIS (Scheer's) enterprise modelling tool, and the first stages in the production of sector reference models.     

Follow-up surveys for census estimates of maternal mortality: experiences from Bolivia and Mozambique

Maternal mortality measurement through special census questions will be a common practice in the 2010 census round. To check this information or make it cause-specific, some countries have experimented with follow-up surveys containing verbal autopsies or triangulation with administrative data. However, follow-up studies can be costly and not without complications. In order to assess the benefits, two such experiences are discussed in detail (Bolivia, 2002; and Mozambique 2007–2008) and two others mentioned more briefly (Islamic Republic of Iran, 1996; and Democratic People’s Republic of Korea, 2008). In the former, several problems were apparent. In Mozambique, the follow-up survey used a cluster sample of 4.5% of deaths, from all causes. This design was adequate for the more common causes, but not for maternal mortality. Another problem was the large proportion of invalid cases (35.1%, plus 16% not verifiable) and the likelihood that there was a similar proportion of omitted deaths. The Bolivian census generated many invalid cases and missing ages, due in part to the flawed design of the questionnaire. This overburdened the follow-up, so that only 15% of the census deaths of women of reproductive age unrelated to pregnancy could be investigated. Once the false positives were eliminated, the results seem consistent with Growth Balance analyses, but the many classification errors compromise confidence in the results. Despite this mixed record of outcomes, it is believed that carrying out a limited number of similar studies in the current census round may be valuable, if appropriate lessons are learned from these experiences.     

The Development of a Student-Run Ambulance

Abstract

Abortion decisions have a potentially meaningful effect on the lives of men. Previous research suggests that both men and women generally believe that men have the right to be involved in such decisions. However, very little research attention has been devoted to identifying individual difference correlates of discrepant levels of endorsement for male involvement in abortion decisions. The extent to which abortion attitudes (on a pro-choice to pro-life continuum), conceptualization of abortion as strictly a female issue, and interest in the issue operate as effective predictors of the appropriate level of male involvement in abortion decisions was examined in a sample of 1,387 college students. Results of a multiple regression analysis revealed that 44% of the variance in male involvement scores was explained by the predictor variables.
