Individual Differences in Personality Conducive to Engagement in Aggression and Violence

This paper examined empirically the value of a conceptual model in which emotional stability and agreeableness contribute to engagement in aggression and violence (EAV) indirectly through irritability, hostile rumination and moral disengagement. Three hundred and forty young adults (130 male and 190 female) participated in the study. The average age of participants was 21 at time 1 and 25 at time 2. Findings attested to the role of basic traits (i.e. agreeableness and emotional stability) and specific personality dispositions (i.e. irritability and hostile rumination) in predisposing to EAV and to the pivotal role of moral disengagement in giving access to aggressive and violent conduct. In particular, the mediational model attested to the pivotal role of emotional stability and agreeableness in contributing directly to both hostile rumination and irritability and indirectly to moral disengagement, and to EAV. Agreeableness and hostile rumination contribute to moral disengagement that plays a key role in mediating the relations of all examined variables with EAV.

Health Promotion in International Documents: Strengths and Weaknesses from the Perspective of Community Empowerment

Informed by a community psychology perspective, which takes an integrated and systemic, or holistic view of health and health promotion, this study presents quali‐quantitative analysis of health documents, produced by the World Health Organization (WHO) over the last 30 years. Textual analysis facilitated the identification of the typical specificities of international WHO health promotion documents, highlighting the lexical contexts of health promotion, particularly in relation to responsibilities for health and the concept of community health. Further, this textual analysis demonstrated how these understandings of health and health promotion have evolved over the last 30 years. Drawing on theory from within the field of community psychology, the changes proposed throughout international WHO documentation in conceptualizations of health and health promotion and in defining strategies to achieve the stated goals of health promotion are discussed critically.

On the recognition of emotional vocal expressions: motivations for a holistic approach

Human beings seem to be able to recognize emotions from speech very well and information communication technology aims to implement machines and agents that can do the same. However, to be able to automatically recognize affective states from speech signals, it is necessary to solve two main technological problems. The former concerns the identification of effective and efficient processing algorithms capable of capturing emotional acoustic features from speech sentences. The latter focuses on finding computational models able to classify, with an approximation as good as human listeners, a given set of emotional states. This paper will survey these topics and provide some insights for a holistic approach to the automatic analysis, recognition and synthesis of affective states.     

Peer and school problems in the lives of urban adolescents: Frequency, difficulty, and relation to adjustment

This study examined the occurrence of problem situations in the peer and school domains and their relation to adjustment among urban adolescents. Students from three urban middle schools (N = 176) serving a predominantly African American population rated 61 problem situations identified in a previous qualitative study and completed measures of adjustment. Ratings of frequency and difficulty confirmed the relevance of these situations for this population. Confirmatory factor analyses suggested that covariation in the frequency and difficulty of problem situations could be represented by separate factors representing peer situations involving friends, other peer situations, and school situations. The number of different problem situations experienced was significantly correlated with physical and relational aggression, delinquency, depression, anxiety, and self-worth. Several of these relations were strongest for peer situations that did not involve friends. There were few gender differences in the strength of these relations.     

Multiple mechanisms for recency with vowels and consonants

Three experiments were conducted to test the hypothesis that the difference in recency effect between vowel-contrasting and stop-contrasting lists of syllables in immediate ordered recall can be explained by item discriminability and regular short-term memory mechanisms, without any recourse to echoic memory or precategorical acoustic storage (PAS). In Experiment 1, the short-term memory mechanisms were manipulated by reducing amount of output interference and length of retention interval. The partial-report technique was used. The most important finding was the usual final-position recency effect (difference in recall between the fifth and sixth serial positions) for the vowel lists but not for the stop lists, regardless of the type of report. Thus the PAS theory could not be rejected. In Experiments 2 and 3, the last item was differentiated from the other items of the list, either by lengthening the interstimulus interval between the last and the next-to-last (Experiment 2) or by increasing the intensity of the last item (Experiment 3). In both cases, an increase of the final-position recency effect was found even for stop lists. Since a drop in recall errors was also obtained for the fourth item when its intensity was increased (von Restorff effect), this final-position recency effect for stop lists is likely to be due to item discriminability, and not to echoic memory for the last item. Item discriminability appeared to be the critical factor.     

Can confidentiality of data pay off?

Ss were administered a self-report personality measure and a social desirability scale under conditions of Confidentiality, Anonymity or Nonanonymity alone. The tester's written assurance that the Ss' disclosures would be kept strictly confidential had a substantial moderating effect (when compared with Nonanonymity alone) on correlations between some subscales of the personality measure and the social desirability scale. In contrast to an earlier finding, there were no appreciable effects of Anonymity when compared with Nonanonymity alone. It appears that confidentiality of data can pay off in terms of increased predictive validity of some self-report personality measures by moderating the potential biasing effect of test response distortion due to socially desirable responding.     

Completeness theorem for dummett's LC quantified and some of its extensions

Dummett's logic LC quantified, Q-LC, is shown to be characterized by the extended frame Q⁺, ,D, where Q⁺ is the set of non-negative rational numbers, is the numerical relation less or equal then and D is the domain function such that for all v, w Q⁺, D_v and if v w, then D _v . D _v D _w . Moreover, simple completeness proofs of extensions of Q-LC are given.     

Bull's Theorem by the Method of Diagrams

We show how to use diagrams in order to obtain straightforward completeness theorems for extensions of K4.3 and a very simple and constructive proof of Bull's theorem: every normal extension of S4.3 has the finite model property.     

Correlations of selected psychomotor and visuomotor tests with initial Dynavision performance

The current study investigated the relationship between Dynavision scores for 36 men and 52 women (M age = 20.5 yr.) and performance on six conventional psychomotor tests which presumably tap similar psychomotor abilities and visuomotor skills. Analysis indicated that initial Dynavision performance was significantly correlated with performance on these common psychomotor tests. These data extend findings that propose the effectiveness of the Dynavision apparatus to assess performance on basic visual-motor and visual-cognitive functions. Taken together with these new results, findings suggest that this apparatus might contribute to psychomotor assessment and may be potentially useful for effective selection and identification of individual differences in human behavioral performance.
