Beyond incubation: an analysis of firm survival and exit dynamics in the post-graduation period

With regard to the survival rates of business incubator (BI) firms, the literature mainly presents findings of failure rates only during the incubation period. Little is known about the survival or exit dynamics of firms after leaving the incubator facilities. This study approaches this research question by examining the survival of 352 firms from five German BIs after their graduation. The findings suggest that graduation causes an immediate negative effect on survivability that lasts up to 3 years after leaving the incubators. Furthermore, heterogeneous patterns of post-graduation exit dynamics between the BIs were observed. It was also found that performance during the incubation period is an indicator of the propensity of business closure after graduation. This study offers valuable insights and implications for all stakeholders of BI-initiatives.      

Signs and symptoms of post-traumatic stress disorder in children

Summary Post-traumatic Stress Disorder in children is a complex interaction of cognitive, affective, and physiological responses to an event that is outside the range of usual human experience and would be markedly distressing to almost anyone. Traumatic stress reactions in children are conscious and unconscious efforts to assimilate an overwhelming event and have been identified in the past as panic reaction, acute grief hysterical reaction, and physical shock. PTSD in children is complicated by multiple issues of developmental stages, family dynamics, physical maturity, genetic predisposition, and cognitive skills. Characteristic symptoms of PTSD which must persist for more than one month include re-experiencing (flashbacks, nightmares); avoidance; numbing of general responsiveness; and persistent autonomic arousal. Children exhibit characteristic PTSD symptoms, but research suggests four criteria specific to traumatized children independent of chronological age and the course of the disorder: 1) visualized and repeatedly perceived memories; 2) repetitive behaviors; 3) trauma-related fears; 4) altered attitudes about life and future orientation. These four criteria appear to remain clustered together in childhood trauma victims even when other diagnosis would appear more appropriate. PTSD in children encompasses a complex spectrum of diagnosis and remains technically intricate for the mental health professional.     

Juveniles' Competence to Stand Trial: A Comparison of Adolescents' and Adults' Capacities as Trial Defendants

Abilities associated with adjudicative competence were assessed among 927 adolescents in juvenile detention facilities and community settings. Adolescents' abilities were compared to those of 466 young adults in jails and in the community. Participants at 4 locations across the United States completed a standardized measure of abilities relevant for competence to stand trial (the MacArthur Competence Assessment Tool—Criminal Adjudication) as well as a new procedure for assessing psychosocial influences on legal decisions often required of defendants (MacArthur Judgment Evaluation). Youths aged 15 and younger performed more poorly than young adults, with a greater proportion manifesting a level of impairment consistent with that of persons found incompetent to stand trial. Adolescents also tended more often than young adults to make choices (e.g., about plea agreements) that reflected compliance with authority, as well as influences of psychosocial immaturity. Implications of these results for policy and practice are discussed, with an emphasis on the development of legal standards that recognize immaturity as a potential predicate of incompetence to stand trial.     

Detection of gamma-butyrolactone (GBL) as a natural component in wine

The compound gamma-butyrolactone (GBL) was found in extracts from samples of unadulterated wines. This finding indicates that GBL is a naturally occurring component in some wines and may be present in similar products. The concentration detected was approximately 5 microg/mL and was easily observed using a simple extraction technique followed by GC/MS analysis. These results illustrate the need to carefully examine an allegedly adulterated sample's matrix before determining a sample was laced with GBL.     

Do the Joneses Help You Keep Up? A Natural Experiment in Exposure to Nonpoor Neighbors

This study capitalizes on a natural experiment in Montgomery County, Maryland, where low-income applicant families are randomly assigned to public housing that is either (a) clustered within seven public housing developments or (b) scattered into market-rate subdivisions via the county's inclusionary zoning policy. Through a survey of 453 public housing residents, we find that adults who lived in scattered public housing reported a lower proportion of low-socioeconomic status (SES) social ties generally and a lower proportion of low-SES neighbors specifically in their social networks. They also counted more high-SES individuals in their social networks, and this effect was related to the amount of time they lived in the neighborhood. Living in scattered public housing had no adverse effect on feelings of neighborhood belonging or satisfaction. The socioeconomic composition of respondents' social networks was associated with two health outcomes for respondents (smoking and depression) and modestly associated with respondents' household income.
