A longitudinal model of executive function development from birth through adolescence in children born very or extremely preterm

Executive function deficits are often reported as a specific weakness in preterm children. Yet, executive function development is still not fully understood. In a prospective longitudinal study, 115 preterm born children, ≤31 weeks of gestation, were recruited at birth and subject to neuropsychological assessments at ages 5.5 and 18 years. By applying Miyake and colleagues’ integrative framework of executive function to our data, two core components of executive function, working memory and cognitive flexibility, were identified through confirmatory factor analysis. Developmental stability was investigated in a serial multiple mediator structural equation model. Biological, medical, and social factors as well as mental development at 10 months were entered as predictors. Both components of executive function were highly stable from 5.5 to 18 years. Gestational age, intrauterine growth, lack of perinatal medical complications, and female sex were positively related to mental development at 10 months, which together with parental education influenced both core executive functions at 5.5 years. Working memory at 5.5 years mediated outcome in working memory at 18 years. In addition to the mediation of cognitive flexibility at 5.5 years, perinatal medical complications and restricted intrauterine growth had a continued direct negative impact on cognitive flexibility at 18 years. The application of a theoretical framework added to our understanding of executive function development in preterm born children. The study supports early identification of executive deficits among children born preterm, as deficits are unlikely to diminish with maturation.     

Integrating commons dilemma findings in a general dynamic model of cooperative behavior in resource crises

The research on commons dilemmas is characterized by innumerable published findings, each standing relatively isolated from the other. To date there is little integration of the findings under a unified concept. The present contribution aims to integrate already existing findings in a general dynamic model of cooperative behavior in resource crises by means of computer simulation. The model postulates that people base their decisions regarding resource use on both ecological and social information. Whether or not ecological or social information will dominate, however, depends on people's social values, attributions, and their perceptions of the state of the resource. The advantage of the simulation method used is that successful integration of the findings can be shown explicitly, as the simulation then replicates the experimental data. With the model presented here, it is also possible to let variables work together whose interaction has not yet been investigated in real experiments. For instance, the simulation model allows us to hypothesize that people, in dependency upon their resource uncertainty and in dependency upon their attributions, utilize a resource completely differently if the resource is in an optimal or sub‐optimal condition.

The word of others

Tyler Burge has argued that one has an a priori prima facie entitlement to believe in the truth of what one takes to have been presented as true by an interlocutor. This thesis, however, is problematic, since the alleged a priori prima facie entitlement to believe in the truth of our seeming understanding of things presented as true to us, rests on the possibility of determining assertoric force on a purely intellectual basis. This thesis is not plausible and Burge's analogy from memory does not support it. Two routes for defending Burge's thesis of the a priori prima facie entitlement to believe in the truth of what has been asserted can be identified: the Transcendental Route and the Intrinsic Rationality Route. David Lewis' account of linguistic convention would serve as a transcendental argument for the a priori prima facie entitlement to believe in the truth of what has been asserted, but flaws in Lewis' theory leave us deprived of any good transcendental argument for such an entitlement. The Intrinsic Rationality Route is in better standing, but we have yet to see an argument for why we should resort to that measure.     

Church-based social interactions and psychotic experiences among Black Americans: findings from the National Survey of American Life

Religious attendance has generally been salutary for mental health, though recent evidence suggests that church attendance has no significant relation with psychotic experiences. This study will examine how various types of church-based social interactions might be related to psychotic experiences. We analysed data from the National Survey of American Life –a representative sample of Black Americans in the United States –and used multivariable logistic regression to examine associations between seven church-based social interaction variables and lifetime psychotic experiences. In separate models, church attendance, church member interaction, and closeness to church members were not significantly associated with psychotic experiences, while greater emotional support, negative social interactions, providing help to other church members and receiving help from fellow church members were associated with increased odds of reporting psychotic experiences. But in a fully adjusted model including all church-based social interaction variables, only negative church interactions and giving help to church members were significantly associated with psychotic experiences. Church-based social interactions did not protect against psychotic experiences, and in some cases increased risk. Future studies should explore why the deleterious aspects of social interactions prevail over the beneficial ones.     

Unapocalyptic Theology: History and Eschatology in Balthasar's Theo‐Drama

In this essay, I evaluate the claim that Hans Urs von Balthasar's interpretation of trinitarian doctrine undermines the importance of history for the Christian God. Where other critics argue that the very distinction between immanent and economic Trinity robs the economy of salvation of theological significance, I contend that the underlying problem lies in how Balthasar restricts the theo‐drama to an event between heaven and earth on the cross of Golgotha. Through this limitation of God's active involvement in history to a single event, Balthasar's theo‐drama becomes an “unapocalyptic theology”, which devalues God's salvific history with the world and the biblical expectation of an eschatological end of history. Furthermore, Balthasar underplays the messianic‐political dimension of the Christian concept of salvation and thereby cements the status quo of a yet unredeemed world.
