The Undecidability of Quantified Announcements

This paper demonstrates the undecidability of a number of logics with quantification over public announcements: arbitrary public announcement logic (APAL), group announcement logic (GAL), and coalition announcement logic (CAL). In APAL we consider the informative consequences of any announcement, in GAL we consider the informative consequences of a group of agents (this group may be a proper subset of the set of all agents) all of which are simultaneously (and publicly) making known announcements. So this is more restrictive than APAL. Finally, CAL is as GAL except that we now quantify over anything the agents not in that group may announce simultaneously as well. The logic CAL therefore has some features of game logic and of ATL. We show that when there are multiple agents in the language, the satisfiability problem is undecidable for APAL, GAL, and CAL. In the single agent case, the satisfiability problem is decidable for all three logics.     

Competent Enough,But Would You Vote for Her? Gender Stereotypes and Media Influences on Perceptions of Women Politicians

Though research has demonstrated that media coverage of men and women politicians differ, fewer studies have examined the dual influence of gender stereotypes and types of media coverage in influencing public perceptions of women politicians. Study 1 (N = 329) examined how pre‐existing attitudes toward women leaders and valence of media message impacted perceptions of a woman senator and evaluations of the media source. Study 2 (N = 246) explored how media focus on a woman politician's personality or ability impacted perceptions of her warmth/likability and competence. Results suggest the media has particular influence on judgments of women politicians' likability (the “competent but cold” effect), providing evidence that women politicians need to be vigilant in monitoring their media depictions.     

Information processing in patients with first episode major depression

Hammar, Å., Kildal, A. B. & Schmid, M. (2012). Information processing in patients with first episode major depression. Scandinavian Journal of Psychology 53, 445–449. Few studies have investigated cognitive functioning in a group of patients experiencing a first episode of depression. The aim of this study was to investigate how patients diagnosed with a first episode of depression perform in effortful and non‐effortful information processing compared to healthy controls. An experimental paradigm based on a visual search test was applied. Thirty‐one patients and thirty‐one healthy controls were included in the study. All patients experienced a severe level of symptom load at the time of testing. Results showed no significant differences between groups under any of the conditions. Findings in the present study indicate that patients with a first episode of depression perform equally to healthy controls in tasks requiring visual attention in both effortful and non‐effortful information processing.     

Explicatio and Complicatio: On the Understanding of the Relationship between God and the World in the Work of Nicholas Cusanus

Cusanus understands the relationship between God and the world through the concept of participation, which he explores through the twin concepts of explicatio (unfolding) and complicatio (enfolding). In Cusanus' view, the dialectics of explicatio and complicatio even apply concerning the relationship between God and humanity. This is explored concerning the relation between divine providence and human freedom, concerning the problem of worship and idolatry, and concerning the understanding of Christ as unfolded divinity and enfolded humanity. It is argued that this allows for an understanding of salvation through grace without reducing the importance of human involvement.     

Self‐Reported Family Socioeconomic Status,the 5‐HTTLPR Genotype,and Delinquent Behavior in a Community‐Based Adolescent Population

Twin and adoption studies have demonstrated a significant contribution of both genetic and environmental factors to antisocial and delinquent behavior. Associations have been reported between the serotonin transporter (5‐HTT) and aggression, and between socioeconomic status (SES), aggression, and serotonergic functions of the brain. We aimed to investigate associations between the 5‐HTTLPR genotype and family SES in relation to delinquent behavior among adolescents. A total of 1,467 17‐ to 18‐year‐old students in the county of Västmanland, Sweden, anonymously completed a questionnaire and gave a saliva sample. Family SES had a U‐shaped relation to delinquency, where adolescents with low and high family SES were the most delinquent. There were curvilinear interactions between the 5‐HTTLPR genotype and family SES in relation to delinquency. Among individuals having high family SES, boys with the LL (homozygous for the long allele) or LS (heterozygous) genotypes and girls with the SS (homozygous for the short allele) or LS (heterozygous) genotypes showed the highest delinquency scores. Among individuals having low family SES, boys with the LL (homozygous for the long allele) genotype and girls with the LS (heterozygous) genotype showed the highest delinquency scores. The present study suggests evidence for an interaction between family SES and the 5‐HTTLPR genotype in relation to juvenile delinquency. Aggr.

Prevalence of Type D personality and factorial and temporal stability of the DS14 after myocardial infarction in a Swedish population

This study examined the prevalence of Type D personality and the temporal stability, internal consistency, and construct validity of the DS14 at three time points after myocardial infarction. The prevalence was 14.0% during hospitalization, 25.1% at 1 month, and 19.2% at 12 months. A total of 6.1% of the patients were classified as Type D personality at all three assessments, whereas 68.4% were stable non‐Type D and 25.6% changed between personality classifications. The DS14 had stable structural validity, but low temporal stability over time, especially from hospitalization to the 1‐month and 12‐month follow‐ups (κ = 0.365 and 0.397, respectively).
