Aggression,anger and hostility: Evaluation of moral disengagement as a mediational process

This study examines how the mechanisms underlying moral disengagement serve as a mediator between anger and hostility and physical and verbal aggression. The study was carried out on 424 participants (61.1% females), aged 15 to 25 years, assessing the direct and indirect effects of the distinct variables using a hierarchical multiple regression analysis and structural equation modeling. The findings suggest that anger and hostility contribute independently and positively to physical and verbal aggression. Moreover, the relationships between anger, hostility, and aggression appear to be mediated by moral disengagement. Indeed, this process of mediation was invariant across sexes, and it tended to be stronger for physical – as opposed to verbal – aggression.     

The development of the first symbolic uses in Mexican children from the pragmatics of object / Desarrollo de los primeros usos simbólicos en niños mexicanos desde la pragmática del objeto

This paper longitudinally studies the emergence and evolution of the first symbolic uses of objects in Mexican children. We observed eight children in triadic interaction with one of their parents and 10 objects in a semi-structured situation at nine, 12, 15 and 18 months old. The children began to use objects symbolically at 12 months, and the duration and frequency increased with age. The highest percentage of the total frequency of symbolic uses, of the four levels identified, was level 1. The frequency of level 4, where two or more symbolic actions occur one after the other, giving rise to ‘symbolic narratives’, increased according to age. These data confirm that knowledge of the rules of canonical uses of objects are the meanings which first symbols base themselves on and that children use the symbolic uses that they are aware of to create ‘symbolic narratives’.     

Personality Traits and Plagiarism: an Empirical Study with Portuguese Undergraduate Students

Academic dishonesty is a major problem and is thus a highly relevant area of inquiry. Considerable research has shown that key traits from the Big Five model of personality are associated with various forms of anti-social behaviour. To date, however, relatively little research interest has been devoted to study the relationship between personality traits and plagiarism. This study attempts to fill this gap by examining the relationship between the Big Five personality traits and the inclination to commit plagiarism by undergraduate students. The main conclusion is that the inclination to plagiarize is negatively associated with Conscientiousness and Agreeableness traits. Neuroticism was not found to be related to the inclination to plagiarize. Implications of the findings are discussed.     

Do private gestures have a self-regulatory function? A case study

One of the most fascinating phenomena in early development is that babies not only understand signs others direct to them and later use them to communicate with others, but they also come to direct the same signs towards themselves in a private way. Private gestures become "tools of thought". There is a considerable literature about private language, but almost nothing about private gestures. Private gestures pose an intriguing communicative puzzle: they are communicative, but with the self. In this paper we study two types of private gestures (signs) before language: (1) private ostensive gestures and (2) private pointing gestures. We show in a case study of one child between 12 and 18 months of age that both are used with a self-reflexive function, as a way of "thinking" what to do, in order to solve a problem in the conventional use of an object. The private gestures become self-reflexive signs.     

Multiple visualisation in data analysis: a ViSta application for principal component analysis

Multiple visualisation (MV) is a statistic graphical method barely applied in data analysis practice, even though it provides interesting features for this purpose. This paper: (1) describes the application of the MV graphical method; (2) presents a number of rules related to the design of an MV; (3) introduces a general outline for developing MVs and shows how MV may be implemented in the ViSta statistical system; (4) illustrates this strategy by means of an example of MV oriented to principal component analysis; and, finally, (5) discusses some limitations of using and developing MVs.     

ADHD Correlates, Comorbidity, and Impairment in Community and Treated Samples of Children and Adolescents

Patterns of correlates, comorbidity and impairment associated with attention-deficit hyperactivity disorder (ADHD) in children and youth were examined in representative samples from the community and from treatment facilities serving medically indigent youth in Puerto Rico. Information from caretakers and youths was obtained using the Diagnostic Interview Schedule for Children, (version IV), measures of global impairment, and a battery of potential correlates. In the community (N = 1,896) and the treated samples (N = 763), 7.5 and 26.2% of the children, respectively, met criteria for DSM-IV ADHD in the previous year. Although the prevalence rates and degree of impairment differed, the general patterns of correlates, comorbidity and impairment were similar in both populations. The exceptions were associated with conduct disorder, anxiety, impairment in the ADHD comorbid group, and age factors that appeared to be related to selection into treatment.     

Revisionism about free will: a statement &; defense

This article summarizes and extends the moderate revisionist position I put forth in Four Views on Free Will and responds to objections to it from Robert Kane, John Martin Fischer, Derk Pereboom, and Michael McKenna. Among the principle topics of the article are (1) motivations for revisionism, what it is, and how it is different from compatibilism and hard incompatibilism, (2) an objection to libertarianism based on the moral costs of its current epistemic status, (3) an objection to the distinctiveness of semicompatibilism against conventional forms of compatibilism, and (4) whether moderate revisionism is committed to realism about moral responsibility.

Factors Affecting HIV Contraceptive Decision-Making Among Women

We examined contraceptive decision-making among African American, Latina, and European American women ages 18–50 years. Logistic regressions examined relationships between demographic and religious factors, unintended pregnancies, sexually transmitted diseases (STDs), reasons for sex, and contraceptive decision-making. Women who were older, single, African American, used pregnancy prevention, and had histories of STDs and unintended pregnancies made contraceptive decisions alone. Older and African American women were more likely to choose no contraception. Among contraceptive users, African Americans used effective methods of pregnancy, but not disease, prevention. Women with STD histories, and younger, more educated women were more likely to use methods that prevent against both pregnancy and disease. Theoretical implications about contraceptive choices among ethnically diverse women are discussed.
