New evidence on the value of birth expectations

Past national surveys regarding birth expectations have usually been restricted to currently married women, a fact which has led demographers to question the usefulness of these data. Because the June 1976 Current Population Survey includes the expectations of all women in a cohort regardless of marital status, it provides the data needed to evaluate biases due to restricted survey universes. At older ages, where there are substantial differences in lifetime expectations between currently married and single women, there are relatively few single women; at younger ages, however, where the proportion of single women in a cohort is relatively large, the differences in expectations are small. This counterbalancing effect makes the lifetime birth expectations of currently married women a close approximation of all women in a cohort. The analysis also indicates that the observed intracohort declines in lifetime birth expectations since 1967 were due largely to the addition at subsequent survey dates of previously unmarried women; nevertheless, some “true” cohort declines also seem to have occurred.     

Sex and cultural differences in the acceptance of functional foods: a comparison of American, Canadian, and French college students

OBJECTIVE: Functional foods (FF)--foods containing nutritional supplements in addition to natural nutrients--have an increasing presence in the marketplace. Expanding on previous research, the authors investigated college students' acceptance of FF. PARTICIPANTS: In September--March 2004, 811 undergraduates in Canada, the United States, and France participated in the study. METHODS: A self-administered questionnaire measured students' general food attitudes and beliefs as well as FF-related knowledge, attitudes, beliefs, and purchase intention. RESULTS: Overall, participants slightly favored FF over traditional foods. However, although most respondents associated FF with positive health benefits, many remained dubious of currently available FF information. In terms of culture and sex, the authors found small but significant divergences in FF knowledge, attitudes, and behaviors. CONCLUSIONS: Stronger labeling and education efforts may increase cross-cultural acceptance of FF by college students.     

Optimum turn-restricted paths,nested compatibility,and optimum convex polygons

We consider two apparently unrelated classes of combinatorial and geometric optimization problems. First, we give compact extended formulations, i.e., polynomial-size linear programming formulations with integer optima, for optimum path problems with turn restrictions satisfying a nested compatibility condition in acyclic digraphs. We then apply these results to optimum convex polygon problems in the plane, by interpreting certain dynamic programming algorithms as sequences of optimum turn-restricted path problems with nested compatibility in acyclic digraphs. As a result, we derive compact extended formulations for these geometric problems as well.     

Employment transitions in the Netherlands, 1980–2004: Are low educated men subject to structural or cyclical crowding out?

This article addresses whether low educated men are displaced from their jobs by higher educated workers in the Netherlands in the period 1980–2004. In particular, we test whether structural or cyclical crowding out is predominant in the Dutch labor market. In order to do so, we try to explain the observed trends in education-specific transition rates to entry into first employment from education, exit from employment into unemployment or inactivity, and re-entry into employment from unemployment or inactivity for men by both business cycle effects (that is, changes in aggregate unemployment rates) and structural effects (that is, changes in labor supply–demand ratios for high educated). Discrete-time event history models are estimated using the OSA Labor Supply Panel 1985–2004. Retrospective information enables to study trends from 1980 onwards, so that structural effects can be distinguished from cyclical effects. The results show that structural crowding out exists at both the worker in- and outflow. First of all, it was observed that a growth in the oversupply of high educated increases the employment exit risk of low educated workers more so than that of higher educated ones. In addition, it was shown that an increase in the oversupply of high educated especially reduces the re-employment chances of low educated unemployed men. There is no evidence found for cyclical crowding out among low educated workers in the Dutch labor market.     

I know there is no justice: Palestinian perceptions of higher education in Jordan

This qualitative study utilizes critical ethnography methods to illustrate Palestinian refugee perceptions of higher education in Jordan. Participants addressed their assimilation to the Jordanian national identity as a means of obtaining education. Content and access to education were more important than assimilation, maintenance of ethnic identity, and a homogeneous national identity. The more immediate need for academic access and social or professional capital thwarted their desire to infuse their ethnic identity in academia.     

Targeting the worst-off for free health care: a process evaluation in Burkina Faso

Effective mechanisms to exempt the indigent from user fees at health care facilities are rare in Africa. A State-led intervention (2004-2005) and two action research projects (2007-2010) were implemented in a health district in Burkina Faso to exempt the indigent from user fees. This article presents the results of the process evaluation of these three interventions. Individual and group interviews were organized with the key stakeholders (health staff, community members) to document the strengths and weaknesses of key components of the interventions (relevance and uptake of the intervention, worst-off selection and information, financial arrangements). Data was subjected to content analysis and thematic analysis. The results show that all three intervention processes can be improved. Community-based targeting was better accepted by the stakeholders than was the State-led intervention. The strengths of the community-based approach were in clearly defining the selection criteria, informing the waiver beneficiaries, using a participative process and using endogenous funding. A weakness was that using endogenous funding led to restrictive selection by the community. The community-based approach appears to be the most effective, but it needs to be improved and retested to generate more knowledge before scaling up.
