Population age structure and private consumption in Spain

In this paper we study the effect of population age distribution upon private consumption expenditure in Spain from 1964 to 1997 using aggregate data. We obtain four main results. First, changes in the population pyramid have substantial effects upon the behaviour of private consumption. Second, the pattern of the coefficients of the demographic variables is not consistent with the simplest version of the life cycle hypothesis. Third, we estimate the impact of the demographic transition upon consumption and find positive values associated with episodes in which the shares of groups of individuals with expenditure levels higher (lower) than the mean increased (decreased). Fourth, the results are robust to alternative specifications for the population age distribution.

El autoconcepto social y el rendimiento académico en la educación artística escolar del alumnado preadolescente

[EN] This correlational study aims to analyse the relationship of the social dimension of the selfconcept with age, educational level, sex and with the academic performance, understood as qualification and as artistic understanding of a group of primary and secondary students. The results show, generally, negative relationship between social self-concept and demographic variables, while statistically significant, although of opposite sign, of the social self-concept with the qualification in the field and with the artistic understanding respectively.

¿Cómo podemos distinguir a los vendedores éticos de los que no lo son?: Implicaciones para el proceso de selección y formación de los comerciales

[ES] Actualmente las organizaciones necesitan dar prestigio a sus equipos de ventas, conocedoras de la influencia que tienen los vendedores sobre el éxito o fracaso de la empresa y de la deteriorada imagen que la sociedad ha tenido tradicionalmente de los vendedores, debido en parte, a la utilización de prácticas éticamente cuestionables por parte de los mismos.

Behavioral profile of adults with Prader-Willi syndrome : correlations with individual and environmental variables

Background: Maladaptive behavior has been reported as a phenotypical feature in Prader–Willi syndrome (PWS). It severely limits social adaptation and the quality of life of children and adults with the syndrome. Different factors have been linked with the intensity and form of these behavioral disturbances but there is no consensus about the cause. Consequently, there is still controversy regarding management strategies and there is a need for new data. Methods: The behavior of 100 adults with PWS attending a dedicated center was assessed using the Developmental Behavior Checklist for Adults (DBC-A) and the PWS-specific Hyperphagia Questionnaire. The DBC-A was completed separately by trained caregivers at the center and relatives or caregivers in a natural setting. Genotype, gender, age, degree of obesity and cognitive impairment were analyzed as variables with a hypothetical influence on behavioral features. Results: Patients showed a relatively high rate of behavioral disturbances other than hyperphagia. Disruptive and social relating were the highest scoring DBC-A subscales whereas anxiety/antisocial and self-absorbed were the lowest. When hospital caregiver and natural caregiver scores were compared, scores for the latter were higher for all subscales except for disruptive and anxiety/antisocial. These effects of institutional management were underlined. In the DBC-A, 22 items have descriptive indications of PWS behavior and were used for further comparisons and correlation analysis. In contrast to previous reports, rates of disturbed behavior were lower in patients with a deletion genotype. However, the behavioral profile was similar for both genotypes. No differences were found in any measurement when comparing type I and type II deletions. The other analyzed variables showed little relevance. Conclusions: Significant rates of behavioral disorders were highlighted and their typology described in a large cohort of adults with PWS. The deletion genotype was related to a lower severity of symptoms. Some major behavioral problems, such as hyperphagia, may be well controlled if living circumstances are adapted to the specific requirements of individuals with PWS.

Evolución de las estrategias de localización residencial.Un caso de estudio Bizkaia

En las dos últimas décadas, en el territorio histórico de Bizkaia al igual que en otras muchas zonas, se observa un fenómeno de expansión de la ciudad hacia sus entornos más próximos primero, y más alejados después. En el espacio de estudio, en concreto, se trata de movimientos migratorios con origen en una zona urbana como es el Gran Bilbao y con destino las zonas rurales adyacentes a la misma. Sin embargo, no todas las zonas limítrofes muestran el mismo grado de atracción, mientras unas se han revelado como focos de atracción residencial, otras han conocido el proceso inverso. En este estudio se profundiza en el tema, a partir del análisis de las variables más relevantes que explican el fenómeno, tanto socio-demográficas, económicas, residenciales como urbanísticas.

Effects of an emotional intelligence program in variables related to the prevention of violence

In recent decades, numerous studies have shown a significant increase in violence during childhood and adolescence. These data suggest the importance of implementing programs to prevent and reduce violent behavior. The study aimed to design a program of emotional intelligence (El) for adolescents and to assess its effects on variables related to violence prevention. The possible differential effect of the program on both genders was also examined. The sample comprised 148 adolescents aged from 13 to 16 years. The study used an experimental design with repeated pretest-posttest measures and control groups. To measure the variables, four assessment instruments were administered before and after the program, as well as in the follow-up phase (1 year after the conclusion of the intervention). The program consisted of 20 one-hour sessions. The pretest-posttest ANCOVAs showed that the program significantly increased: (1) El (attention, clarity, emotional repair); (2) assertive cognitive social interaction strategies; (3) internal control of anger; and (4) the cognitive ability to analyze negative feelings. In the follow-up phase, the positive effects of the intervention were generally maintained and, moreover, the use of aggressive strategies as an interpersonal conflict-resolution technique was significantly reduced. Regarding the effect of the program on both genders, the change was very similar, but the boys increased assertive social interaction strategies, attention, and emotional clarity significantly more than the girls. The importance of implementing programs to promote socio-emotional development and prevent violence is discussed.

Aplicación de metodología estadística para predecir la mortalidad de pacientes con neumonía

[es]Con esta memoria se pretende crear una herramienta de trabajo que ayude a los médicos a clasificar a los pacientes que padecen neumonía en distintos grupos de riesgo dependiendo de su gravedad. Para ello, hemos estudiado la regresión logística, que relaciona la variable respuesta mortalidad con el resto de variables (datos demográficos, antecedentes médicos y datos clínicos y exploratorios del paciente). Una vez creado el score a partir del modelo de regresión, hemos querido validarlo y compararlo con otros dos que utilizan los neumólogos: el CURB-65 y el FINE.
