In this paper we present a spatial equilibrium model where search frictions hinder the immediate reallocation of workers both within and across local labour markets. Because of the frictions, firms and workers find themselves in bilateral monopoly positions when determining wages. Although workers are not at each instant perfectly mobile across cities, in the baseline model we assume that worke...

BACKGROUND Recent studies in a few industries have shown that the likelihood of IgE-mediated sensitization increases with increasing exposure. The shape of the exposure-response relationships and modification by age, sex, and smoking habit has hardly been studied. OBJECTIVE The purpose of this study was to determine exposure sensitization relationships for rat sensitization and to evaluate th...

The objective of this study was to assess whether the Brazilian Workers' Food Program (WFP) is associated with changes in the nutritional status of workers in the transformation industry. We conducted a cross-sectional, observational, comparative study, based on prospectively collected data from a combined stratified and two-stage probability sample of workers from 26 small and medium size comp...

OBJECTIVES To investigate whether workers in Swedish sulfate mills have an increased risk of death from certain malignancies that have previously been linked to the pulping process. METHODS Subjects of the study (n=2480) were men aged 40-75 at death during 1960-89 in the parishes surrounding four sulfate mills. Exposure assessment was based on information from the personnel files in the mills...

In North Delhi, India, 83 community workers (anganwadi workers) in the ICDS project Alipur participated in a survey designed to assess their knowledge and attitude about breast feeding and to identify gaps in their knowledge of breast feeding. 98.7% knew that breast feeding should be begun immediately after birth. 92.7% knew that the newborn should receive the colostrum. Only 56.6% knew that...

BACKGROUND There are different street substance users' communities (SSUCs). Typology of SSUCs in Tehran, Iran was approached in this qualitative study. METHODS Using content analysis and saturation principles, 22 street-outreach workers were recruited and interviewed. Data were analyzed using open, axial, and selective coding. FINDINGS Three types of SSUCs were identified. SSUCs were differ...

Communities in both Europe and North America are encouraging the development of cultural amenities as a strategy for improving quality of life, attracting and retaining productive workers, and promoting urban revitalization. If these policies are effective then the presence of cultural amenities should increase the local demand for housing, and the value of cultural amenities should be reflecte...

After holding the offices of house physician and assistant house surgeon at King's College Hospital, London, in the summer of 1859 he was appointed house surgeon to the North Staffordshire Infirmary, which post he held until November, 1862. His ...

Laboratory strains of house mice (Mus domesticus) are increasingly used as model organisms in evolutionary physiology, so information on levels of genetic variation is important. For example, are levels of genetic variation comparable to those found in populations of wild house mice? We studied allozymes to estimate genetic variation in outbred Hsd:ICR mice, which have been used in several stud...
