The aim of this study was to survey the work-relatedness of symptoms and diseases among engineered nanomaterials handling workers by questionnaire. A total of 258 exposed workers and 200 comparison workers were recruited from 14 nanomaterials handling factories in Taiwan. In addition to current disease status (prevalence), we classified the diseases worsened by employment (worsened by work). Th...

The related applications are limited due to the static characteristics on existing relatedness calculation algorithms. We proposed a method aiming to efficiently compute the dynamic relatedness between Chinese entity-pairs, which changes over time. Our method consists of three components: using cooccurrence statistics method to mine the co-occurrence information of entities from the news texts,...

BACKGROUND Until recently, no evidence-based criteria were available to determine the work-relatedness of low back pain (LBP) in an individual worker. Incidence figures for LBP that can be qualified as occupational disease (OD) are scarce. We studied the trend in the number of OD notifications due to LBP in the Netherlands and estimated incidence rates of LBP-related OD notifications. METHODS...

This article explores the motivations behind Russian men’s altruistic sperm donation using Alderfer's Existence-Relatedness-Growth (ERG) model. Among sample of 86 men, altru-istic motivation is mostly driven by existence and relatedness. Correlations tests indicated two patterns: 1) men needs are more willing to maintain contact with future child less prone self-promotion; 2) relatedness demon-...

Crystalline silica has been classified as a definite carcinogen (Group 1) causing lung cancer by the International Agency for Research on Cancer (IARC). In Korea, crystalline silica has been the most common causal agent for workers to apply to the Korea Workers' Compensation and Welfare Service (KWCWS). We used KWCWS data to evaluate workers' crystalline silica exposure levels according to thei...

BACKGROUND AND AIMS Research on the ability of plants to recognize kin and modify plant development to ameliorate competition with coexisting relatives is an area of very active current exploration. Empirical evidence, however, is insufficient to provide a sound picture of this phenomenon. METHODS An experiment was designed to assess multi-trait phenotypic expression in response to competitio...

BACKGROUND Knowledge on the impact of the psychosocial work environment on the occurrence of stress-related disorders (SRDs) can assist occupational physicians in the assessment of the work-relatedness of these disorders. AIMS To systematically review the contribution of work-related psychosocial risk factors to SRDs. METHODS A systematic review of the literature was carried out by searchin...

According to self-determination theory, people have three basic psychological needs: relatedness, competence, and autonomy. Of these, the authors reasoned that relatedness need satisfaction is particularly important for promoting prosocial behavior because of the increased sense of connectedness to others that this engenders. In Experiment 1, the authors manipulated relatedness, autonomy, compe...

Evidence from studies with adult rodents indicates that individual recognition enables distinctions between familiar individuals irrespective of relatedness (but including close kin) and a separate mechanism enables discriminations based on genetic relatedness without prior familiarity. For example, adult mice could assess the extent of their genetic relatedness to unfamiliar individuals using ...

Research has demonstrated the importance of relatedness perceptions to self-determined motivation in physical education. Therefore, studies have begun to examine the social factors contributing to feelings of relatedness. The purpose of this study was to examine teacher (perceived emotional support) and peer (acceptance, friendship quality) relationship variables to feelings of relatedness, mot...
