OBJECTIVE To explore a possible causal relationship between psychosocial work characteristics and mental health. METHODS Using longitudinal data from the Maastricht Cohort Study on "Fatigue at Work" (n = 2332), the effects of changes in job demands and decision latitude on subsequent changes in need for recovery and prolonged fatigue were studied. RESULTS Increasing job demands are a signif...
OBJECTIVES This study is analyzing the unexpected reversed or lacking association between high adjustment latitude and sickness presence by examining whether it is due to confounding. MATERIAL AND METHODS Questionnaires were sent in 2004 and 2005 to a cohort of individuals aged 25-50 years, selected from the Statistics Sweden's register of the Swedish population. Information from 2397 individ...
Cretaceous represents one of the hottest greenhouse periods in the Earth's history, but some recent studies suggest that small ice caps might be present in non-polar regions during certain periods in the Early Cretaceous. Here we report extremely negative δ(18)O values of -18.12‰ to -13.19‰ for early Aptian hydrothermal zircon from an A-type granite at Baerzhe in northeastern China. Given that ...
New impact craters at five sites in the martian mid-latitudes excavated material from depths of decimeters that has a brightness and color indicative of water ice. Near-infrared spectra of the largest example confirm this composition, and repeated imaging showed fading over several months, as expected for sublimating ice. Thermal models of one site show that millimeters of sublimation occurred ...
[1] On Mars annual mean surface temperature near ±60 latitude varies predominately with precession and is not closely related to annualmean insolation. Based on the last few million years of orbital history, the precession cycle dominates in a narrow latitude range 54 –65 , in which the margins of the two ice-rich permafrost layers in each hemisphere happen to lie, while mean annual temperature...
OBJECTIVE The aim of this study was to examine changes in working hours, shift work, psychological and physical job demands, job control and job insecurity in Taiwanese employees by gender and age during the period of 2001 to 2010. METHODS The study subjects were 36,750 men and 27,549 women, aged 25-64, from 4 rounds of cross-sectional surveys of representative employees. Psychosocial work co...
Observations of radar speckle patterns tied to the rotation of Mercury establish that the planet occupies a Cassini state with obliquity of 2.11 +/- 0.1 arc minutes. The measurements show that the planet exhibits librations in longitude that are forced at the 88-day orbital period, as predicted by theory. The large amplitude of the oscillations, 35.8 +/- 2 arc seconds, together with the Mariner...
BACKGROUND The Japanese government is an important shareholder in the Japanese tobacco industry. Negotiations to develop the WHO's historic Framework Convention on Tobacco Control (FCTC) were based on consensus, resulting in countries needing to agree to the lowest acceptable common denominator in clause development. OBJECTIVE To illustrate Japan's role in negotiating key optional language in...
This paper presents an angular correlation analysis of the Green Bank 4.85 GHz radio catalog (Gregory & Condon 1991) of 54,579 sources (S > 25 mJy). The Green Bank catalog is found to be complete to S 35 mJy over 20 < 74 , 0 h < 24 h , and Galactic latitude jbj 10. The 2-point angular correlation function shows evidence for the clustering of radio sources, with a power-law distribution consiste...
