The ability of group members to discriminate against foreigners is a keystone in the evolution of sociality. In social insects, colony social structure (number of queens) is generally thought to influence abilities of resident workers to discriminate between nestmates and non-nestmates. However, whether social origin of introduced individuals has an effect on their acceptance in conspecific col...

In this paper we estimate the size of weekend effects for seven emotions and then explore their main determinants for the working population in the United States, using the Gallup/Healthways US Daily Poll 2008-2012. We first find that weekend effects exist for all emotions, and that these effects are not explained by sample selection bias. Full-time workers have larger weekend effects than do p...

I have read with great interest the paper of Ghaffari et al. [1] ‘Effect of psychosocial factors on low back pain in industrial workers’. The Iranian prospective study confirms the aetiological role of job strain for low back pain (LBP). However, a rather surprising finding is reported, but not discussed: social support at the workplace apparently increases LBP prevalence. In logistic regressio...

The resolution of social conflict in colonies may accord with the interests of the most numerous party. In social insect colonies with single once-mated queens, workers are more closely related to the workers' sons than they are to the queens' sons. Therefore, they should prefer workers to produce males, against the queen's interests. Workers are capable of producing males as they arise from un...

The aerial spray prediction model AgDRIFT embodies the computational engine found in the near-wake Lagrangian model AGricultural DISPersal (AGDISP) but with several important features added that improve the speed and accuracy of its predictions. This article summarizes those changes, describes the overall analytical approach to the model, and details model implementation, application, limits, a...

Research shows that social work graduate programs offer little education in suicide prevention and intervention, yet social workers' experiences and attitudes regarding suicide education are unknown. This Web-based survey of 598 social workers found that almost all respondents had worked with at least one suicidal client, but most received little, if any, training in suicide prevention or inter...

Participants 19 English speaking carers who attended the ward and 25 healthcare workers. Informal carers were those who provided physical or social care or assistance for another person. Without this help, the recipient would need health, social, or voluntary sector service intervention. Healthcare workers were nurses, physiotherapists, occupational therapists, dieticians, ambulance personnel, ...

BACKGROUND Burnout is a psychosomatic syndrome widely observed in Chinese medical workers due to the increasing cost of medical treatment, excessive workload, and excessive prescribing behavior. No studies have evaluated the interrelationship among occupational burnout, work-family conflict, social support, and job satisfaction in medical workers. The aim of this study was to evaluate these rel...

Crowdsourcing has become a popular service computing paradigm for requesters to integrate the ubiquitous humanintelligence services for tasks that are difficult for computers but trivial for humans. This paper focuses on crowdsourcing complex tasks by team formation in social networks (SNs) where a requester connects to a large number of workers. A good indicator of efficient team collaboration...

OBJECTIVE To use social network analysis to design more effective strategies for vaccinating healthcare workers against influenza. DESIGN An agent-based simulation. SETTING A simulation based on a 700-bed hospital. METHODS We first observed human contacts (defined as approach within approximately 0.9 m) performed by 15 categories of healthcare workers (eg, floor nurses, intensive care uni...
