This paper presents the results and policy implications of a study that examined the spawning of founders who had previously been employed at large corporations. We found that spawning of founders is positively associated with the parent companies' productivity, innovativeness, and headquarter location. Furthermore, we found that the spin‐off per employee rate is higher in smaller establishments. We also found that the local entrepreneurial culture is significant in explaining local spawning of founders. Finally, we present new empirical evidence on the crucial role of successful homegrown companies in regional cluster development. More specifically, we found that the existence of successful homegrown companies is significantly correlated with the level of the regional entrepreneurial activity. This finding is consistent with the finding of many cluster development case studies. Thus, we argue that successful homegrown companies have a unique role in cluster development. This role can seldom be replaced by nonhomegrown companies. This is related to the notion that prior to the development of an entrepreneurial cluster, some intangible precondition should be realized such as the appearance of local role models and a shift toward a more entrepreneurial culture. In a more general perspective, these results support the notion that knowledge‐based regional development is a complex process that requires a long‐term and continuously adjusting supporting policy rather than being based mainly on attracting established companies' R&D centers to the region. 相似文献

Traumatic cardiac ventricular ruptures in children are rare. Only a single case of left ventricular rupture due to child abuse has been reported. We report a child who sustained a fatal left ventricular apical rupture. It appeared to have resulted from hydrostatic forces resulting from abusive blunt thoracic injury. That he was being abused was previously missed when he was presented to the emergency department with facial pyoderma. It was not noted that he also had lip and oral mucosal injury, sites not affected by staph toxins. As a result, his underlying, abusive and secondarily infected, facial flow type scald burn was not appreciated. Within a week thereafter his fatal injury occurred, accompanied by extensive and obvious associated abusive injuries. Postmortem high‐detail whole body computed tomography scanning aided the autopsy. Although rare, ventricular rupture from abusive blunt thoracic injury can occur. 相似文献

This study tests a model of the effects on child behavioral outcome of the child's exposure to partner violence and child abuse, in children who have experienced the two forms of victimization either separately or together. Recognizing that family contextual factors play an important role in influencing child outcome, an ecological model is proposed that designates family stress as the principal exogenous factor, with effects on child outcome mediated through caretaker distress, partner violence, and child abuse. The sample consists of 100 confirmed cases of physically abused New York City schoolchildren, ages 9 to 12 years, and their families, and 100 nonmaltreated classmates, matched for gender, age, and, as closely as possible, for race, ethnicity, and socioeconomic status, and their families. Child behavioral outcome is assessed by classmates for antisocial, prosocial, and withdrawn behavior and by parents and teachers for externalizing and internalizing problem behavior. Results are generally consistent with the hypothesis that partner violence and caretaker distress, both associated with family stress, increase the risk for child abuse and thereby raise the child's risk for poor outcome. Implications of differences among raters for the model's applicability, and implications of the results for clinical intervention, are discussed. 相似文献
