We use new offshoring data and new workforce micro-data with occupational classifications to investigate how an increase in the global supply of IT workers has affected the occupational composition of the US IT workforce. Our estimates suggest that when firms open offshore captive centers for IT employment, domestic IT employment skews towards occupations requiring more “personal” inputs, such ...

METHODS We surveyed 941 unionized Las Vegas hotel room cleaners about their experiences with work-related pain and with employers, physicians, and workers' compensation.

BACKGROUND A low socioeconomic position (SEP) is consistently associated with ill health, sickness absence (SA) and permanent disability, but studies among young employees are lacking. We examined the interrelationships between education, occupational class and income as determinants of SA among 25-34-year-old employees. We also examined, whether the association between SEP and SA varied over t...

OBJECTIVES Exposure to high molecular weight (HMW) allergens that provoke immune reactivity through an IgE-mediated pathway has been associated with a decreased risk of B-cell lymphoma. The present analysis was conducted to assess the associations between occupational exposure to specific HMW allergens and the risk of B-cell, T-cell, and Hodgkin's lymphomas. METHODS We analyzed data from 2,29...

For square contingency tables with the same row and column ordinal classifications, we propose a model of quasi-symmetry using the row and column marginal ridits scores. Using the proposed model, the model of equality of marginal mean ridits and the model of equality of marginal variance ridits, we give a theorem such that the symmetry model holds if and only if all these models hold. Moreover,...

Difficulties in sustaining posture can present with features associated with hyperactive behaviour listed in DSM-5 and ICD-10 classifications for ADHD. Information from a system measuring motor activity during a neurocognitive test (QbTest), occupational therapist reports and Conners rating scales are compared between cases with and without posture problems. Weakness in sustaining posture resul...

Hazard Banding (HB) is a process of allocating chemical substances in bands of increasing health hazard based on their hazard classifications. Recent Control Banding (CB) tools use the classifications of the United Nations Global Harmonized System (UN GHS) or the European Union Classifications, Labelling and Packaging (EU CLP) which are grouped over 5 HBs. The use of CB is growing worldwide for...

OBJECTIVE To analyze the prevalence of cases suggestive of noise-induced hearing loss (NIHL) among metalworkers who were potentially exposed to occupational noise (from 83 to 102 dB). METHODS A cross-sectional study was carried out in a metalworking company providing services in Rio de Janeiro, Brazil. Clinical and occupational data on 182 workers who were active between November 2001 and Mar...
