BACKGROUND Past research has shown links between both children's aggressive behaviour and a lack of prosocial behaviour to later maladaptation. Both types of behaviours have also been identified as crucial in children's social and emotional development and later (mal)adaptation. However, little is known about the way they predict each other over time. METHODS We utilised a large, ethnically d...

Associations between cannabis use and psychotic outcomes are consistently reported, but establishing causality from observational designs can be problematic. We review the evidence from longitudinal studies that have examined this relationship and discuss the epidemiologic evidence for and against interpreting the findings as causal. We also review the evidence identifying groups at particularl...

Researchers have retrospectively analyzed the training intensity distribution (TID) of nationally and internationally competitive athletes in different endurance disciplines to determine the optimal volume and intensity for maximal adaptation. The majority of studies present a "pyramidal" TID with a high proportion of high volume, low intensity training (HVLIT). Some world-class athletes appear...

The aim of this study was to test the hypothesis that job-search intensity has a pivotal role for (re)employment of unemployed individuals. In our study we tested a heuristic model that included sets of variables potentially influencing (re)employment. Those were: biographic characteristics, employment motivation factors, job search constraints, and job-search intensity. We expected job-search ...

In this research, the convective heat transfers of turbulent water fluid flow in alternating oval tubes is studied using computational fluid dynamics. The purpose of the study is to analyze the heat transfer enhancement and secondary internal flows under different alternate angles. Also, comparing the effect of two schemesfor the domain discretization to be used in the soluti...

Conducting survey interviews on the internet has become an attractive method for lowering data collection costs and increasing the frequency of interviewing, especially in longitudinal studies. However, the advantages of the web mode for studies with frequent re-interviews can be offset by the serious disadvantage of low response rates and the potential for nonresponse bias to mislead investiga...

introduction:ventilator- associated pneumonia(vap),as defined by the centers for disease control and prevention (cdc),is a pneumonia that occurs in a patient receiving mechanical ventilation that develops 48 hours or more after initiation of ventilation.re-intubation which occur within 72 hours of planned extubation may effect vap incidence.the aim of this study was to determine vap incidence i...

Meal machine, experimental laboratory, status symbol, domestic prison, or the creative and spiritual heart of the home? Over the course of the past century no other room has been the focus of such intensive aesthetic and technological innovation, or as loaded with cultural significance. Kitchen design has been both a central concern of modernism and fundamental to our concept of modern life (Mo...
