Private money,public scrutiny? Contrasting perspectives on remittances

Migrant remittances have received unprecedented attention over the past decade and scholars have interpreted remittance flows from a range of vantage points. In this article, we explore the meaning of remittances from three perspectives – (1) as an ingredient of terrorism and crime; (2) as a contribution to development; and (3) as an obstacle to integration. We explore these perspectives through an analysis of eight years of public debate in Norway and a review of the academic literature. Our analysis shows that remittances are open to public scrutiny, often within a strongly normative framework. Such public scrutiny is at odds with the private nature of remittances and affects migrants' everyday lives both structurally and emotionally. This scrutiny of remittances also suggests underlying assumptions about migrants' legitimate loyalties and belonging that fail to take adequate account of their multiple attachments.     

Child mortality in India: the community-level effect of education

When assessing the health benefits of increased education in less developed countries, many researchers have been concerned about the omission of important determinants of an individual's education from the models. The study presented here shows that one should also be concerned about the limitations of the individual-level perspective. According to a multilevel discrete-time hazard model estimated with data from the National Family Health Survey II, the average education of women in a census enumeration area has a strong impact on child mortality, in addition to the effect of the mother's own education. The lower child mortality associated with women's autonomy is taken into account in this estimation. Results from similar models for various health and health-care variables suggest that the effect of community education, like that of individual education, operates through the use of maternity services and other preventive health services, the child's nutrition, and the mother's care for a sick child.     

Expected utility with lower probabilities

An uncertain and not just risky situation may be modeled using so-called belief functions assigning lower probabilities to subsets of outcomes. In this article we extend the von Neumann-Morgenstern expected utility theory from probability measures to belief functions. We use this theory to characterize uncertainty neutrality and different degrees of uncertainty aversion.We are grateful to Birgit Grodal, Salvatore Modica, David Schmeidler, and an anonymous referee for comments, help, and encouragement.

The impact of a participatory organizational intervention on job stress in community health care institutions

The aim of the present study was to investigate the effect of a short-term participatory intervention in health care institutions in Norway on workers' control, other job characteristics, job stress, subjective health and job satisfaction. Participants (including managers and supervisors) were randomly allocated to intervention groups and to a control group. Actions to solve problems based on the employees' own perceptions of the main problems were seen as the key motivators for organizational improvement and increased control at the task and office level in the work situation. The main stressors identified by the participants in this study were lack of information, communication and respect between professions, as well as the need for professional and personal development. The participatory intervention had a positive, but limited effect on work-related stress, job characteristics, learning climate and management style, and seemed to have started a beneficial change process. There were no negative short-term effects on work-related stress and job demands. Organizational interventions may be a potential training ground for acquiring participatory skills and resources, and if sustained after the intervention period, they can have long-term effects on problem solving, job stress and employee satisfaction.     

Main and Interaction Effects of Women's Education and Status on Fertility: The Case of Tanzania

The analysis is based on individual 1996 TDHS data combined withaggregate data from the 1988 census and the 1991/1992 TDHS. When varioussources of spuriousness are taken into account, it is found that giving awoman more education reduces her fertility much less than suggested byunivariate tabulations of the total fertility rate. Expansion of primaryeducation contributes to only a slightly higher age at first birth, and theeffect on higher-order birth rates is not significant. Changes in post-partum insusceptibility outweigh those in fertility desires and use ofmodern contraception among women not wanting an additional child.Secondary school enrollment influences fertility more markedly, inparticular because of a later first birth. Effects of women's status areestimated in models for actual fertility as well as fertility desires, post-partum insusceptibility and contraceptive use, using up to six macro- ormicro-level indicators. All significant effects suggest that empowerment ofwomen will tend to push fertility down, net of education. The significantinteractions between women's status and education point in differentdirections, but a majority of them indicate that education has the mostpronounced effect on fertility in the more egalitarian regions and amongwomen with relatively high individual status.     

Forgone labor participation and earning due to childbearing among Norwegian women

Individual-level retrospective data from the Family and Occupation Survey of 1988 are used to assess the time diverted from gainful employment because of the presence of children in two Norwegian birth cohorts. We find that a two-child mother born in 1950, whose births occurred in her early twenties, lost 6.6 women-years up to age 37, compared to a childless woman. By matching information on registered income with the survey data, we estimate that her lost income amounts to $151,000 at 1990 prices. After taxation the loss is $98,000. Women with fewer than 12 years of schooling seem to forgo more labor market activity by reason of childbearing than do their better-educated counterparts. The pattern is less clear with respect to the loss of income.     

Detection of biomass change in a Norwegian mountain forest area using small footprint airborne laser scanner data

Different approaches for estimation of change in biomass between two points in time by means of airborne laser scanner data were tested. Both field and laser data were collected at two occasions on 52 sample plots in a mountain forest in southeastern Norway. In the first approach, biomass change was estimated as the difference between predicted biomass for the two measurement occasions. Joint models for the biomass at both occasions were fitted using different height and density variables from laser data as explanatory variables. The second approach modelled the observed change directly using the change in different variables extracted from the laser data as explanatory variables. In the third approach we modelled the relative change in biomass. The explanatory variables were also expressed as relative change between measurement occasions. In all approaches we allowed spline terms to be entered. We also investigated the aptness of models for which the residual variance was modeled by allowing it to be proportional to the area of the plot on which biomass was assessed. All alternative models were initially assessed by AIC. All models were also evaluated by estimating biomass change on the model development data. This evaluation indicated that the two direct approaches (approach 2 and 3) were better than relying on modeling biomass at both occasions and taking change as the difference between biomass estimates. Approach 2 seemed to be slightly better than approach 3 based on assessments of bias in the evaluation.     

The Current Duration Approach to Estimating Time to Pregnancy

Abstract. Time‐to‐pregnancy (TTP) is the duration from the time a couple starts trying to become pregnant until they succeed. It is considered one of the most direct methods to measure natural fecundity in humans. Statistical tools for designing and analysing time to pregnancy studies belong to survival analysis, but several features require special attention. Prospective designs are difficult to carry out and retrospective (pregnancy‐based) designs, being widely used in this area, do not allow efficiently including couples remaining childless. A third possible design starts from a cross‐sectional sample of couples currently trying to become pregnant, using current duration (backward recurrence time) as basis for the estimation of TTP. Regression analysis is then most conveniently carried out in the accelerated failure time model. This paper surveys some practical and technical‐statistical issues in implementing this approach in a large telephone‐based survey, the Epidemiological Observatory of Fecundity in France (Obseff).
