Encuesta compuesta por un conjunto de sencillas cuestiones cuyo objetivo es la valoración cuantificada del estado actual (madurez) en Buen Gobierno y Gobierno TI en la Universidad de Alicante, fundamentalmente como consecuencia de la aplicación del modelo de cartera estratégica de proyectos TI: priorización estratégica de proyectos + gobernanza de la ejecución + analisis de los resultados.

We analyze and compare the advertising by food brands on regular TV networks (traditional advertising) with videos by child YouTubers (influencing) in Spanish. An exploratory study is conducted by means of a content analysis of 304 videos, with 22 variables grouped into 4 categories: obesogenic features, innovative trends, prevalence of ultra-processed vs. healthy products in advertising, and marketing style.

Se ha realizado la caracterización colorimétrica de cuatro pantallas Retina correspondientes a tres modelos de iPad: iPad4 (2013), iPadAir (2014), iPad17 (2017) e iPad19 (2019). Dicha caracterización se ha llevado a cabo mediante la medida experimental de los valores triestímulo de 1000 colores y una posterior interpolación hasta el conjunto de colores reproducibles en la pantalla. Los colores medidos son el resultado de una matriz de 10x10x10 niveles digitales de encendido de los pixeles de cada pantalla (canales Rojo-Verde-Azul). Para cada uno de los dispositivos se han construido dos ficheros de datos (.mat) que contiene las siguientes variables: • posxy: coordenadas del punto de la pantalla del dispositivo donde se han realizado las medidas experimentales de los valores triestímulo, con origen en el centro de la pantalla, • x e y: matrices de coordenadas espaciales de cada pixel de la pantalla, en este caso 2048x1536 pixeles para las 3 pantallas, • tablaLUT: tabla 3DLUT calculada por interpolación lineal o cúbica a partir de las 1000 medidas experimentales y compuesta por 16777216x6 datos. Cada fila corresponde a un color de los 2563 posibles (256 niveles digitales por canal, 3 canales). Las tres primeras columnas recogen los niveles digitales de cada color, normalizados entre 0 y 1. Las tres últimas columnas corresponden a los valores triestímulo XYZ de ese color.

Objective: The purpose of this study is to provide reliability and validity evidence of the Adult Self-Report Scale (ASRS) scores on different versions and scoring procedures in a Spanish substance use disorder (SUD) sample. Method: The sample was made up of 170 outpatients diagnosed with SUD. The ASRS, the Mini-International Neuropsychiatric Interview (MINI), and the Substance Dependence Severity Scale were administered. Results: The results of the confirmatory factor analysis (CFA) showed adequate fit to the structure proposed by the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) in the 18-item version. On the screening scale, best fit was found for a model with two correlated factors (inattention and hyperactivity). The exploratory factor analysis (EFA) showed that the ADHD items converge and are differentiated from symptoms of withdrawal. The regression analyses showed that severity of dependence is explained by the ASRS scores. Conclusion: Both versions of the ASRS showed adequate psychometric properties. The polytomous or dichotomous score is relevant in patient classification.

Background: Protective behavioral strategies (PBS) have shown utility in reducing alcohol-related negative consequences. The Protective Behavioral Strategies Scale (PBSS) is one of the most widely used and well-validated instruments for evaluating these strategies. However, a Spanish adaptation of this or any other measure of PBS is not available. We aimed to provide a Spanish version of PBSS-20 and examine its psychometric properties. Method: We recruited 538 undergraduate students from three Spanish universities (mean age = 21.2; females = 78%). Measures included the Spanish-PBSS-20 (S-PBSS-20), Young Adult Alcohol Consequences Questionnaire (YAACQ), Daily Drinking Questionnaire, and frequency of alcohol use, drunkenness, and binge drinking. Results: Our results support the use of the original 3-factor structure of the PBSS-20. Internal consistency reliability ranged between 0.71-0.77, and evidence of validity was provided according to the expected relationships with other variables. Exploratory factor analyses provided evidence of convergent/discriminant validity of S-PBSS-20. Conclusions: The results suggest that PBSS-20 is a useful instrument for assessing protective behavioral strategies in alcohol users. The S-PBSS-20 could be useful for research on alcoholrelated protective behavioral strategies and consequences, and could also inform the design of educational interventions for promoting the use of protective strategies and reducing alcohol-related negative consequences.

The acceptance or rejection of classmates is one of the most widely recognized determinants of wellbeing in childhood. This study analyses psychosocial adjustment and sociometric status in primary education pupils, and possible differences by gender. A cross-sectional survey was undertaken in Huelva (Spain). The surveyed schools were selected using a stratified random sampling technique with both public and private elementary schools. Sample was composed of 247 4th grade students. Data revealed gender differences in psychosocial adjustment, particularly in terms of prosocial behavior in girls and behavioral problems in boys. Popular and rejected statuses presented opposing adjustment profiles, particularly in hyperactive symptoms and behavioral problems. When the sample was separated by gender, the differences between the types of status in emotional symptomatology and prosocial behavior disappeared. In addition, the differences between statuses were greater in boys, and were defined mainly by hyperactivity, whilst for girls these differences were more apparent in behavioral problems.

This work explores the relationships between principals’ motivations for entering the principalship and the difficulties they experienced during their first year as principals. Survey data were collected from a sample of 2042 Spanish principals. They answered a questionnaire assessing intrinsic and extrinsic motivations, difficulties experienced when doing instructional, informational, and administrative tasks, and other personal and contextual characteristics. The scales developed to measure motivations and difficulties displayed adequate psychometric properties. The results showed the preponderance of intrinsic motivations. Administrative mundane tasks were perceived as the most difficult ones. We also found that non-administrative instructional tasks were more difficult for those principals who were more extrinsically motivated. Some gender differences were observed in motivations and difficulties. Women placed lower value on extrinsic motivations than men. Furthermore, while the difficulty of administrative tasks in their first year as principal was placed higher by women than men, those tasks that are more relationship-oriented (i.e. informative and instructional tasks) were rated as more difficult by men than women. Although internal incentives and administrative overload characterize most of the public Spanish principals, some findings pointed to the possibility of other profiles of principals that should be investigated in further studies. Implications for the design of principalship training are also discussed
