Psycho-neural Identity as the Basis for Empirical Research and Theorization in Psychology: An Interview with Mario A. Bunge

Mario Bunge is one of the most prolific philosophers of our time. Over the past sixty years he has written extensively about semantics, ontology, epistemology, philosophy of science and ethics. Bunge has been interested in the philosophical and methodological implications of modern psychology and more specifically in the philosophies of the relation between the neural and psychological realms. According to Bunge, functionalism, the philosophical stand of current psychology, has limited explanatory power in that neural processes are not explicitly acknowledged as components or factors of psychological phenomena. In Matter and Mind (2010), Bunge has elaborated in great detail the philosophies of the mind-brain dilemma and the basis of the psychoneural identity hypothesis, which suggests that all psychological processes can be analysed in terms of neural and physical phenomena. This article is the result of a long interview with Dr. Bunge on psychoneural identity and brain-behaviour relations.     

The effects of acute alcohol consumption on recovery from a simulated rugby match

In this study, we investigated the effects of acute post-exercise alcohol consumption on measures of physical performance, creatine kinase, and immunoendocrine function in the 48 h following a rugby game simulation. Ten male senior rugby union players completed a rugby game simulation after which they consumed either 1 g of alcohol per kilogram of body mass or a non-alcoholic control beverage. Agility, 15 m sprint, countermovement jump, and srummaging performance were assessed pre-simulation and 24 and 48 h post-simulation. White blood cell count, testosterone, cortisol, and creatine kinase were measured before the simulation and 30 min, 12, 24, 36, and 48 h after the simulation. One week after the first trial, participants completed the second simulation after which the other beverage was consumed. The acute consumption of alcohol after a rugby game simulation negatively affected countermovement jump performance in the days following the simulation (P = 0.028). No differences between treatments were observed for the other criterion measures made in this study. In conclusion, after 80 min of a simulated rugby game, the consumption of 1 g of alcohol per kg body mass negatively impacts lower body vertical power output. However, performance of tasks requiring repeated maximal muscular effort is not affected.     

Chronic Illness and Preterm Infants: Family Stress and Support Issues

As the survival rate for children with complex medical conditions has increased, the body of knowledge regarding childhood chronic illness has grown. While the initial focus of this literature was the effect of the illness on the child, recent studies have focused on chronic illness and broader family issues. The transactional and family systems perspectives suggest the need for longitudinal studies of chronically ill infants from the point of diagnosis. Although a few studies of relatively healthy preterm infants have documented family stress levels, there is a paucity of research on the effects of parenting a very low birthweight infant with complex medical needs. The Chronically Ill Infant Intervention (CIII) Project and its broad based interdisciplinary intervention is used to illustrate the changing needs of this population. Preliminary analyses of specific intervention needs during the infants' first 18 months are discussed in relation to the reduction of family stress.     

Labor Market Returns for Graduates of Hispanic-Serving Institutions

Latinos have become the largest minority group in American postsecondary education, a majority of whom attend two- or four-year Hispanic-Serving Institutions (HSIs). However, little is known about labor market outcomes as result of attending these institutions. Using a unique student-level administrative database in Texas, and accounting for college selectivity, we examine whether attending an HSI influences labor market outcomes ten years after high school graduation for Latino students in Texas. We find no difference in the earnings of Hispanic graduates from HSIs and non-HSIs. This analysis represents one of the first to examine the labor market outcomes for Latino students in this sector of education accounting for critical factors that include a student’s high school and community context.     

The factor invariance of student ratings of instruction under three sets of directions

This research addressed itself to the issue of the validity of student ratings of instruction, describing and comparing the factor patterns obtained under three different sets of directions. Graduate education students (n=414) were randomly assigned to one of three conditions: administrator use, instructor use, and student use. Subjects in each condition received a different cover letter which explained the purported use to which their ratings were to be put and which asked them to rate their course and instructor on a 33-item rating scale. Data were factor analyzed using principal-axes factor method followed by an oblique transformation. The factor patterns obtained were then compared using the coefficient of congruence. While two clusters (organization/structure and rapport/interaction) emerged across all three conditions, a third cluster appeared which was unique to each condition. The coefficients of congruence obtained generally indicated that the factors could not be considered invariant across the three conditions.     

Unemployment and Work Interruption among African American Single Mothers: Effects on Parenting and Adolescent Socioemotional Functioning

Using interview data from a sample of 241 single African American mothers and their seventh- and eighth-grade children, this study tests a model of how 2 economic stressors, maternal unemployment and work interruption, influence adolescent socioemotional functioning. In general, these economic stressors affected adolescent socioemotional functioning indirectly, rather than directly, through their impact on mothers' psychological functioning and, in turn, parenting behavior and mother-child relations. Current unemployment, but not past work interruption, had a direct effect on depressive symptomatology in mothers. As expected, depressive symptomatology in mothers predicted more frequent maternal punishment of adolescents, and this relation was fully mediated by mothers' negative perceptions of the maternal role. More frequent maternal punishment was associated with increased cognitive distress and depressive symptoms in adolescents, and consistent with predictions, these relations were partially mediated by adolescents' perceptions of the quality of relations with their mothers. Increased availability of instrumental support, as perceived by mothers, predicted fewer depressive symptoms in mothers, less punishment of adolescents, and less negativity about the maternal role. Both economic stressors were associated with higher levels of perceived financial strain in mothers, which in turn predicted adolescents' perceptions of economic hardship. Adolescents who perceived their families as experiencing more severe economic hardship reported higher anxiety, more cognitive distress, and lower self-esteem.

Vertical alliance networks: The case of university-biotechnology-pharmaceutical alliance chains

Many young biotechnology firms act as intermediaries in tripartite alliance chains. They enter upstream partnerships with public sector research institutions, and later form commercialization alliances with established, downstream firms. We examine the alliance activity in a large sample of biotechnology firms and find: (i) firms with multiple in-licensing agreements are more likely to attract revenue-generating alliances with downstream partners; however, (ii) the positive relationship between in-licenses and downstream alliances attenuates as firms mature, and (iii) the diversity and the quality of the academic connections of firms’ principals influences their chances of successfully acquiring commercialization rights to scientific discoveries in universities.
