Background and aims: Low Birth Weight is an important health scale of each country, because it is one of the major factors predicting normal growth and development and even survival of new-born and infants. Previous studies of employed women show various complications such as low birth weight due to job type. In this study, we decided to evaluate the association of Low Birth Weight with job con...
BACKGROUND Job strain (i.e., high job demands combined with low job control) is a frequently used indicator of harmful work stress, but studies have often used partial versions of the complete multi-item job demands and control scales. Understanding whether the different instruments assess the same underlying concepts has crucial implications for the interpretation of findings across studies, h...
OBJECTIVE To assess the association between job strain and binge eating as well as the effect-modifying influence of body mass index (BMI) on this association. METHODS A total of 11,951 active civil servants from the multicenter Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) was included in this cross-sectional analysis. Job strain was assessed using the Demand-Control-Support Que...
This prospective four-wave study examined (i) the causal direction of the longitudinal relations among job demands, job control, sleep quality and fatigue; and (ii) the effects of stability and change in demand-control history on the development of sleep quality and fatigue. Based on results of a four-wave complete panel study among 1163 Dutch employees, we found significant effects of job dema...
BACKGROUND The long-term effects of leisure-time physical activity (LTPA) on job strain have not been assessed in a large prospective population-based cohort study. AIMS To examine the relationship between the LTPA and the prevalence of job strain. METHODS The participants were 861 full-time employees (406 men and 455 women), aged 24-39 years in 2001, from the ongoing Cardiovascular Risk in...

This paper consists of two parts. In the first auxilliary part, we deal with sets with cyclic order. For any such set O we introduce following [BG] a cocycle l : G × G → Z valued in {0,±1} ⊂ Z on the group G of automorphisms of O. The cohomology class of l in H(G,Z) will be called the Euler class. If K is an ordered field, then the projective line P(K) has a cyclic order and PSL2(K) acts orderp...
With touch-screen devices becoming ever more ubiquitous, sketch holds great promise as an intuitive and efficient mode of input compared to classic alternatives. This has motivated a major revival of interest in vision-based analysis of sketches, notably in sketch-based image retrieval (SBIR). Superior to classic SBIR methods, finegrained SBIR (FG-SBIR) methods [1] are proposed to make fine-gra...
Let G be an almost simple simply connected group over C, and let BunaG(P ,P) be the moduli scheme of principal G-bundles on the projective plave P, of second Chern class a, trivialized along a line P ⊂ P. We define the Uhlenbeck compactification U G of BunaG(P , P), which classifies, roughly, pairs (FG,D), where D is a 0-cycle on A 2 = P − P of degree b, and FG is a point of Bun G (P,P), for va...
Each nonnegative matrix, ( : , 1,.., ) ij W w i j n , is a possible spatial weight matrix summarizing spatial relations between n spatial units. Here each spatial weight, ij w , typically reflects the “spatial influence” of unit j on unit i . Following standard convention, we here exclude “self influence” by assuming that 0 ii w for all 1,.., i n (so that W has a zero diagonal). The fol...
