Screen media usage, sleep time and academic performance in adolescents: clustering a self-organizing maps analysis.
2014
Screen media usage, sleep time and socio-demographic features are related to adolescents' academic performance, but interrelations are little explored. This paper describes these interrelations and behavioral profiles clustered in low and high academic performance. A nationally representative sample of 3,095 Spanish adolescents, aged 12 to 18, was surveyed on 15 variables linked to the purpose of the study. A Self-Organizing Maps analysis established non-linear interrelationships among these variables and identified behavior patterns in subsequent cluster analyses. Topological interrelationships established from the 15 emerging maps indicated that boys used more passive videogames and compu…
The Phenomenology of Specialization of Criminal Suspects
2012
A criminal career can be either general, with the criminal committing different types of crimes, or specialized, with the criminal committing a specific type of crime. A central problem in the study of crime specialization is to determine, from the perspective of the criminal, which crimes should be considered similar and which crimes should be considered distinct. We study a large set of Swedish suspects to empirically investigate generalist and specialist behavior in crime. We show that there is a large group of suspects who can be described as generalists. At the same time, we observe a non-trivial pattern of specialization across age and gender of suspects. Women are less prone to commi…

The impact of the perception of body weight on WLB was also analyzed, with particular attention being paid to overestimation. Methods: The data of 639,194 European adolescents aged 11, 13, and 15 years who participated in the Health Behaviour in School-aged …
Physical and cognitive doping in university students using the unrelated question model (UQM): Assessing the influence of the probability of receivin…
2018
Study objectives: In order to increase the value of randomized response techniques (RRTs) as tools for studying sensitive issues, the present study investigated whether the prevalence estimate for a sensitive item π̂$_{s}$ assessed with the unrelated questionnaire method (UQM) is influenced by changing the probability of receiving the sensitive question p. Material and methods: A short paper-and-pencil questionnaire was distributed to 1.243 university students assessing the 12-month prevalence of physical and cognitive doping using two versions of the UQM with different probabilities for receiving the sensitive question (p ≈ 1/3 and p ≈ 2/3). Likelihood ratio tests were used to assess wheth…

Reduction in the Incidence of Type 2 Diabetes With the Mediterranean Diet
2010
OBJECTIVE To test the effects of two Mediterranean diet (MedDiet) interventions versus a low-fat diet on incidence of diabetes. RESEARCH DESIGN AND METHODS This was a three-arm randomized trial in 418 nondiabetic subjects aged 55–80 years recruited in one center (PREDIMED-Reus, northeastern Spain) of the Prevención con Dieta Mediterránea [PREDIMED] study, a large nutrition intervention trial for primary cardiovascular prevention in individuals at high cardiovascular risk. Participants were randomly assigned to education on a low-fat diet (control group) or to one of two MedDiets, supplemented with either free virgin olive oil (1 liter/week) or nuts (30 g/day). Diets were ad libitum, and no…
Masculinity and Privileges: Acknowledge as a Potencial Articulator of Change
2021
El artículo que se presenta a continuación analiza discursivamente la percepción que los hombrestienen acerca de su situación de ventaja o privilegio (los dividendos patriarcales según Raewyn Connell, 1995) en tanto que varones y en un sistema de dominación como el patriarcado (en su momento actual). Se reflexiona desde la teoría y la empiria sobre su negación o reconocimiento y los mecanismos de investigación a través de los cuales podemos acceder a estas ideas y relatos en relación con los privilegios masculinos en los varones. Desde un punto de vista técnico-metodológico abordamos la complejidad deacceder a este tipo de conocimiento y algunas de las herramientas que desde la socioantropo…
Efecto de supresión y mediación en el contexto de la intervención psicosocial: Diferencias, similitudes y ejemplos
2013
ResumenEl presente trabajo compara el efecto mediador y el supresor de una tercera variable. Ambos efectos parcelan la varianza de la variable dependiente (Y). La mediación es la reducción, tras introducir una tercera variable (Z) en el modelo, de la proporción de varianza explicada directamente por la variable independiente (X) en la variable criterio (Y) y la supresión es el incremento de la proporción de varianza explicada directamente por la independiente en la variable criterio, al incluir la tercera variable en el modelo. Se analizan las características y diferencias de cada efecto y se examina en qué situaciones se produce uno u otro. Cada situación, compuesta de tres variables corre…
Terveyskasvatus tutkimus- ja koulutusalana sekä arjen käytäntöinä
1992
Artikkelissa esitellään terveyskasvatuksen yliopistollista asiantuntijakoulutusta, terveyskasvatustutkimuksen osa-alueita ja tutkimuskohteita sekä käytännön terveyskasvatuksen tehtäviä ja päämääriä. Terveyskasvatuksen neljä suurta tehtävää ovat sivistävä tehtävä, virittävä tehtävä, mielenterveystehtävä ja muutosta avustava tehtävä. Terveyskasvatustutkimuksen osa-alueina nähtiin terveyskasvatuksen teoreettinen tutkimus, terveyskäyttäytymistutkimus, terveyskasvatuksen arviointitutkimus sekä terveyskasvatuksen yhteiskunnallinen tutkimus. Terveyskasvatuksen kokonaisvaltaiseksi määritelmänä esitettiin seuraava: ”Terveyskasvatuksen tavoitteena on kasvatuksellisin ja viestinnällisin keinoin tukea …
