Becoming the best: by beating or ignoring the best? Toward an expanded view of the role of managerial selection in complex and turbulent environments

This paper explores how the rules that guide search affect organizational adaptation in complex and turbulent environments. Our consideration of such rules extends beyond search scope—i.e., exploitation of current technologies vs. exploration of new technologies—to include focus on competition. We consider two types of competitive focus—i.e., external, where the choice of focal technology to be improved is influenced by information about other organizations and internal, where it is not influenced by others. We refer to this expanded set of rules as managerial selection and vary it to explore how it affects organizational adaptation. Employing an agent based simulation model, built on the framework of NKC fitness landscapes, we consider multiple types of interdependencies within and between technologies and across competitors. We show that in the presence of these multiple interdependencies, the ability of organizations to adapt is conditioned as much or more by the focus of search than by its scope. In particular, we observe that in simple and stable environments, organizational adaptation is enhanced by an external focus but in complex and turbulent environments, such external focus is counterproductive.     

The Role of Metacognition in Pathological Gambling: A Mediation Model

Pathological gambling involves multitudinous costs related to financial, legal, and public health care aspects, as well as to specific psychological disorders. Despite the overall evidence suggesting that comorbid disorders represent a risk factor for pathological gambling, there is scant evidence on the appropriate treatments for gamblers with such disorders. In this context, metacognitive therapy is an interesting approach because it considers psychological disorders as a result of the activation of perseverative cognitive processes and attentional strategies in response to inner events. Several studies report that metacognition is associated with different psychological problems. This study investigated the relationship among comorbid disorders, metacognition, and pathological gambling. 69 pathological gamblers at the first hospital admission and 58 controls drawn from general population (matched for age, gender, education) completed a battery of self report instruments: Symptom Checklist-90-R, Metacognition Questionnaire 30, South Oaks Gambling Scale. Compared to controls, pathological gamblers showed higher level of comorbid symptomatology and metacognition. Correlation analyses showed that: comorbid symptomatology and metacognition were positively and significantly correlated with pathological gambling; metacognition was positively and significantly associated with comorbid symptomatology. Mediation analysis indicated that dysfunctional metacognitive strategies could have an indirect effect on pathological gambling mediated by concurrent psychological disorders. These findings provide some implications for gambling treatment programs: pathological gamblers should be screened for psychiatric disorders, and metacognitive therapy could be considered a correct treatment of pathological gamblers. Metacognitive therapy might lead to the reduction of the pathological gambling by the diminishing of the concurrent psychological disorders.     

Prenatal Development of Interlimb Motor Learning in the Rat Fetus

The role of sensory feedback in the early ontogeny of motor coordination remains a topic of speculation and debate. On E20 of gestation (the 20th day after conception, 2 days before birth), rat fetuses can alter interlimb coordination after a period of training with an interlimb yoke, which constrains limb movement and promotes synchronized, conjugate movement of the yoked limbs. The aim of this study was to determine how the ability to express this form of motor learning may change during prenatal development. Fetal rats were prepared for in vivo study at 4 ages (E18–21) and tested in a 65‐min training‐and‐testing session examining hind limb motor learning. A significant increase in conjugate hind limb activity was expressed by El9, but not El 8 fetuses, with further increases in conjugate hind limb activity on E20 and E21. These findings suggest substantial development of the ability of fetal rats to modify patterns of interlimb coordination in response to kinesthetic feedback during motor training before birth.     

Adolescent Health and Well‐Being in the Twenty‐First Century: A Global Perspective

Adolescence is a critical developmental period with long‐term implications for the health and well‐being of the individual and for society as a whole. The most significant factors to adolescents' health are found in their environments, and in the choices and opportunities for health‐enhancing or health‐compromising behaviors that these contexts present (e.g., exposure to violence, supportive families). Inadequate contexts represent a failure to invest in and protect adolescents, a choice to alienate rather than integrate them into society. This article describes a number of societal trends, including growing poverty and income disparities, government instability, the changing health‐care system, the spread of HIV/AIDS, increased migration and urbanization, changing family and cultural contexts, and new information technology. The health implications of these trends for the well‐being of adolescents in the 21st century are contemplated.     

Relationship between vigorous exercise frequency and substance use among first-year drinking college students

OBJECTIVE: The authors explored the relationship between self-reported vigorous exercise frequency and alcohol, tobacco, and other drug (ATOD) use behaviors among first-year college students who self-identified as drinkers. PARTICIPANTS: The authors recruited 391 freshman college students in Northeast Florida to participate in an alcohol abuse prevention study. METHODS: The authors conducted a multivariate analysis of variance to assess the relationship between vigorous exercise frequency and 6 measures of ATOD use at baseline. RESULTS: Frequent exercisers drank significantly more often and a significantly greater quantity than did infrequent exercisers. However, frequent exercisers smoked cigarettes significantly less often than did infrequent exercisers. CONCLUSIONS: These findings suggest that vigorous exercise frequency is differentially associated with alcohol and cigarette consumption among college students. Researchers should further examine the reasons for these differences.
