First Exits from the Swedish Labor Market Due to Disability

Nowadays, with an increasingly aging population, an increasing proportion of the population on disability benefits, and an implicitly lower level of economic output and foregone tax revenue, disability has become a major public policy issue in many countries. Estimating both single risk and competing risks models on a Swedish longitudinal database, this study analyzes the risk of exit from the labor market due to disability at a certain age, conditional on having remained in the labor force until that age. The explanatory variables did not have identical coefficients across destination types. For example, the estimated single risk model shows that a higher level of education decreased the hazard of exiting the labor market with a disability pension, while the estimated competing risks model suggests that a higher level of education increased the hazard of exiting with a partial disability pension, but it decreased the hazard of exiting with a full disability pension.

Limiting distributions of MLE and UMVUE in the biparametric uniform distribution

In this paper, we study the asymptotic distributions of MLE and UMVUE of a parametric functionh(θ₁, θ₂) when sampling from a biparametric uniform distributionU(θ₁, θ₂). We obtain both limiting distributions as a convolution of exponential distributions, and we observe that the limiting distribution of UMVUE is a shift of the limiting distribution of MLE.     

Immigration Policies and Social Determinants of Health: Is Immigrants’ Health at Risk?

The purpose of this study was to examine the impact of immigration legislation on Latino immigrants within the social determinants of health framework to understand the impact of such legislation on the immigrant’s health. While the socio-political climate in California is geared towards more pro-integration immigration policies, findings indicate that immigrants still experiences poor treatment in the form of microaggressions, horizontal discrimination, and institutional discrimination. This poor treatment may be an indication of residual anti-immigrant sentiment that remains in the state as well as a spillover effect from the anti-immigrant legislation being passed in neighboring states or national rhetoric. The findings overlap with four domains of the social determinants of health framework including economic stability, education, health and access to care, and social and community context. Implications for practice, policy and research are discussed.

ON FUZZY GOAL PROGRAMMING—SOME COMMENTS

This paper pertains to goal programming with fuzzy goals and fuzzy priorities. Hannan [1], in his paper on fuzzy goal programming, alludes to the difficulty of handling fuzzy priorities and further notes that a method that this author proposed [2] may lead to incorrect results. In this note, the general problem of goal programming with fuzzy priorities is reexamined, along with the solution to the specific example presented in my original paper [2]. It is shown that the method for handling fuzzy priorities originally proposed by this author does indeed capture the relative importance of goals.     

Risk: For Whom? Representations of Mining Activity by Different Social Actors in the Molango Manganese District of Hidalgo,Mexico

Previous studies have shown high levels of manganese exposure and neurocognitive damage in the population living in the mining zone in Molango, Mexico. One of the objectives of the Intersectoral Group on Environmental Management for the mining district has been to provide public participation in the risk management plan. To achieve this, it is important to know how the different social actors represent the mining activity. The objectives of this study were to characterize the social representations of the mining activity by different social actors. A qualitative design was used based on in‐depth interviews of residents, public officials, and a mining company representative. The analysis was conducted according to themes for each group of actors. Essentially, distinct social representations of the different mining activities were identified. Residents viewed mining activities as synonymous with contamination and, therefore, as having affected all areas of their environment, health, and daily life. These activities were seen as a collective risk. The public officials and the mining company held that there was no evidence of harm and saw mining activities as a generator of regional development. Harm to health and the environment were seen as a stance taken by the communities in order to obtain economic benefits from the company. These images of the “other” are shaped by social, political, and cultural factors. They make it difficult for the actors to reach cooperative agreements and thereby affect progress on the risk management plan. Decisionmakers need to take these differences into account when promoting social participation.
