E. S. Barratt proposed the term impulsive aggression to define a kind of aggression that is characterized by acting without thinking because of high levels of impulsivity. Previous research using psychometric measures has shown that impulsivity and aggression are related as far as psychometric measures are concerned. Nevertheless, most of the research has been done with samples of university students. Our research tests whether this relationship is stable across different samples; university students, teenagers and workers. Our results show that impulsivity and aggression have a consistent pattern of relationships across these samples, with impulsivity being specially related to emotional and instrumental aspects of aggression. Furthermore, the effects of anger on aggression seem to show a pattern of relationship that depends on age, with a tendency to physical aggression in young people and verbal aggression in adults. Keywords: impulsivity, impulsive aggression, anger E. S. Barratt ha propuesto el término agresión impulsiva para definir un tipo de agresión que se caracteriza por actuar sin pensar debido a altos niveles de impulsividad. Investigaciones anteriores con medidas psicométricas han mostrado que impulsividad y agresión están relacionadas en lo que a las medidas psicométricas se refiere. Sin embargo, la mayoría de las investigaciones han empleado muestras de estudiantes universitarios. Nuestro trabajo trata de comprobar si esta relación se mantiene en muestras diferentes. Nuestros resultados indican que impulsividad y agresión muestran una pauta de relación consistente across these samples, estando la impulsividad especialmente relacionada con los aspectos emocionales e instrumentales de la agresión. Además, los efectos de la ira sobre la agresión muestran al parecer una pauta de relación dependiente de la edad, encontrándose una tendencia a la agresión física en gente joven y la agresión verbal en adultos.

Screening by ofloxacin disk was carried out on 1158 strains of Streptococcus pneumoniae in order to investigate the in vitro bacteriostatic activity of penicillin G, levofloxacin, moxifloxacin, telithromycin, linezolid, pristinamycin and quinupristin-dalfopristin against ofloxacin-intermediate and -resistant S. pneumoniae strains. It was concluded that these new antimicrobial agents could be useful for the treatment of pneumococcal infections caused by penicillin-sensitive and -resistant S. pneumoniae, and would represent a valid therapeutic option for patients allergic to beta-lactams, should they prove to be potent in vivo.

The selection process of team leaders is fundamental if the effectiveness of teams is to be guaranteed. Human values have proven to be an important factor in the behaviour of individuals and leaders. The aim of this study is twofold. The first is to validate Schwartz's survey of human values. The second is to determine whether there are any relationships between the values held by individuals and their preferred roles in a team. Human values were measured by the items of the Schwartz Value Survey (SVS) and the preferred roles in a team were identified by the Belbin Self Perception Inventory (BSPI). The two questionnaires were answered by two samples of undergraduate students (183 and 177 students, respectively). As far as the first objective is concerned, Smallest Space Analysis (SSA) was performed at the outset to examine how well the two-dimensional circular structure, as postulated by Schwartz, was represented in the study population. Then, the results of this analysis were compared and contrasted with those of two other published studies; one by Schwartz (2006) and one by Ros and Grad (1991). As for the second objective, Pearson correlation coefficients were computed to assess the associations between the ratings on the SVS survey items and the ratings on the eight team roles as measured by the BSPI.

Título: Diferencias de personalidad en los solicitantes de licencia de armas (ensayos propioceptivos y verbales).Resumen: El Diagnóstico Propioceptivo del Temperamento y del Carácter (DP-TC) (Tous, 2008), que se basa en el rendimiento de la motricidad fina sin visión del propio cuerpo, se utiliza junto con una prueba verbal de personalidad (Durán, García, García, & Martínez, 2001) para examinar las diferencias de personalidad entre los solicitantes del permiso de armas (GL) y la población en general (GP). Los resultados del MANOVA mostraron diferencias significativas entre los dos grupos en la prueba DP-TC, el grupo GL obtiene una puntuación más alta en Emocionalidad (temperamento) e Impulsividad (temperamento y carácter) y una puntuación menor en Toma de Decisiones (temperamento y carácter) y Estado de Ánimo (temperamento); mostrándose más pesimistas que el grupo GP. En el grupo GL, el rendimiento del DP-TC se comparó con el resultado de la prueba verbal, por medio de un análisis de componentes principales con rotación varimax. Los resultados del temperamento del DP-TC mostraron sólo una asociación con las variables verbales, corroborando así la idea de que el temperamento está más libre de la influencia social. Al comparar los resultados de la prueba verbal con la propioceptiva observamos que la escala Emocionalidad del DP-TC era congruente con la escala verbal Fuerza del Ego, mientras que los resultados en Neuroticismo eran opuestos y podrían haber sido falsificados, con el fin de obtener la licencia de armas. Palabras clave: componentes disposicionales de conducta; componentes intencionales de conducta; control motor; diagnóstico propioceptivo; solicitantes de la licencia de armas. Abstract:The Proprioceptive Diagnosis of Temperament and Character (DP-TC) test (Tous, 2008), which assesses fine motor performance without vision of one's own body, was used together with a verbal personality test (Durán, García, García, & Martínez, 2001) to examine personality differences between a group of gun licence (GL) applicants and a group from the general population (GP). MANOVA results showed significant differences between the groups on the DP-TC test, with the GL group scoring higher on Emotionality (Temperament) and Impulsivity (Temperament and Character) and lower on Decision-Making (Temperament and Character) and Mood (Temperament). In the GL group, fine motor performance on the DP-TC test was compared with the verbal test results by means of a principal components analysis with varimax rotation. The results corresponding to the Temperament dimensions of the DP-TC test showed only one association with the verbal test variables, thus corroborating the notion that Temperament has little social influence. Comparison of the proprioceptive and verbal tests showed that the results on the Emotionality scale of the DP-TC were consistent with those on the Ego-strength scale of the verbal personality test, but not with Neuroticism; this suggests that these subjects might fake their replies in order to obtain the gun licence....

The aim of the given preliminary study was to check whether any changes in fi ne motor behaviour exist in switching from single to double task (with cognition charge) in proprioceptive sensory graphomotor test conditions. Ten students (fi ve males and fi ve females), aged from 20 to 30 years old, took part in the experiment - precision of tracking of the models in both experimental test conditions: without and with cognitive task (counting numbers back). The variables for assessment were obtained with use of the digitalized proprioceptive diagnostics (Tous, 2008; Tous, J.M., Muiños, Tous, O., & Tous J, 2012) of Mira y Lopez laboratory (University of Barcelona) that transformed the measurements of drawn lines on a touch screen from pixels into millimetres. As results showed, in the proprioceptive test condition, the changes in deviations related to spatial (lineograms) or line length variability (parallels) did not reach any statistical signifi cance; while the changes in line length performance (lineograms) were found signifi cant (that corresponds to inhibition- -excitatory balance of nervous system).

This study analyses age-dependent differences in proprioceptive fine motor precision and related features of personality and individual differences in order to define more critical ages for higher risks for traffic accidents. The Proprioceptive Diagnostics of Temperament and Character was applied to 196 participants (12 -95 years old). Observable variables (deviations in spatial orientation and size reproduction in different movement types) were registered for both hands and analysed for the precision mechanics and their corresponding meaning in a personality test. Sex effects were also controlled. The results describe the most critical periods for having higher risks for traffic accidents.

We present the results of a principal-components analysis of the Personality Adjective Check List (PACL) at the item level, rather than at the scale level. The PACL was constructed by Strack (1987) to evaluate the personality scales proposed by Millon (1981). Data were obtained from a sample of normal adolescents. A scree test was applied to determine the number of factors to be extracted, and the retained factors were then rotated using a varimax procedure. Using the data from this second analysis, congruence coefficients were calculated by correlating the factor weights from the two analyses of men and women. Results reveal the existence in the whole sample of five unipolar personality factors, which we have called: Aggressive, Conscientious, Inhibited, Impulsive and Gregarious. These are not similar to those obtained from a sample of normal adults.
