This study aims to explain and elaborate a new model for the business environmental hostility in small and medium enterprises in the science and technology park in Kermanshah (Iran). The research method is a mixed method. Content analysis was used in the qualitative part, and a confirmatory factor analysis was used in the quantitative section. In the qualitative section for the environmental ho...

ACADEMIC ABSTRACT A contingency based model shows that firm performance for technology services organizations (TSOs) is positively related with entrepreneurial autonomy and technology intensity; and negatively related with environmental hostility. Further, firm size is found to have a moderating effect on the relationship of TSO performance with entrepreneurial autonomy, technology intensity an...

Hostility has been shown to be a vulnerability marker for various health problems. The present study examined genetic and environmental contributions to individual differences in hostility in South Korean adolescent and young adult twins. Seven hundred and nineteen same- and opposite-sex twin pairs aged from 13 to 23 years completed a hostility scale. The scalar sex-limitation model was applied...

The aim of this study was to determine the genetic contribution to the variation in testosterone and the aggression-hostility-anger (AHA) syndrome in middle-aged twins. Moreover, the relation between testosterone and this syndrome, and possible common genetic mechanisms were investigated. Towards this end, blood samples were collected at two time points; the AHA syndrome was measured using thre...

Drawing on environmental determinism and environmental management perspectives, this study examines the roles of strategy in the relationship between environment and performance in new ventures. With data from 184 ventures in China’s high technology industries, I found that new venture strategies play differential roles in dealing with different environmental dimensions to affect performance. I...

This study investigated genetic and environmental influences on the associations between mother–child relationship quality (warmth and hostility) and adolescent conduct problems and cigarette use. Participants included 601 mothers and adolescent twin pairs (aged 12–17 years). Mothers and adolescents provided separate reports of mother-to-child warmth and hostility. A combined measure of mother ...

A phenomenological model for species spreading which incorporates the Allee effect, a species’ maximum attainable growth rate, collective dispersal rate and dispersal adaptability is presented. This builds on a well-established reaction-diffusion model for spatial spreading of invading organisms. The model is phrased in terms of the “hostility” (which quantifies the Allee threshold in relation ...

OBJECTIVE Three psychosocial characteristics associated with cardiovascular disease (CVD)-depression, hostility, and social support-tend to correlate with one another. However, the causes of each characteristic and why they tend to co-occur are not completely understood. Therefore, the current study used a twin design to examine the relative contributions of genetic and environmental influences...
