Prevalence and risk factors of actinic keratosis in patients attending Italian dermatology clinics
2017
Background: Actinic keratosis (AK) is a common keratinocyte intraepidermal neoplasia. Objective: To assess AK prevalence and potential risk factors in patients attending Italian general dermatology clinics. Materials & methods: This retrospective study was conducted on clinical data from consecutive white outpatients aged ≥30 years, attending 24 general dermatology clinics between December 2014 and February 2015. AK prevalence (entire population) and multivariate risk factor analysis (patients with current/previous AK and complete data) are presented. Results: AK prevalence in 7,284 patients was 27.4% (95% CI: 26.4-28.4%); 34.3% in men and 20.0% in women (p<0.001). Independent AK ris…
Control de la comprensión durante la lectura de textos de ciencias en inglés. ¿Están preparados los estudiantes universitarios españoles para integra…
2011
Se presenta un estudio empírico realizado con estudiantes universitarios. Se estudió el control de la comprensión durante la lectura de textos de ciencias en inglés. Los resultados muestran dificultades importantes en el procesamiento de las macroideas respecto de las microideas y esas dificultades disminuyen muy lentamente a medida que crece el nivel de dominio del inglés. Dado que el procesamiento de macroideas es necesario para el aprendizaje profundo de los contenidos de ciencias, estos estudiantes tendrían graves dificultades en seguir un Grado universitario impartido en inglés, de acuerdo con los cánones del Espacio Europeo de Educación Superior. El inglés parece requerir una revisión…
Social Network Analysis and Qualitative Interviews for Assessing Geographic Characteristics of Tourism Business Networks.
2015
This study integrates quantitative social network analysis (SNA) and qualitative interviews for understanding tourism business links in isolated communities through analysing spatial characteristics. Two case studies are used, the Surselva-Gotthard region in the Swiss Alps and Longyearbyen in the Arctic archipelago of Svalbard, to test the spatial characteristics of physical proximity, isolation, and smallness for understanding tourism business links. In the larger Surselva-Gotthard region, we found a strong relationship between geographic separation of the three communities on compartmentalization of the collaboration network. A small set of businesses played a central role in steering col…
Does Sedentary Behavior Predict Academic Performance in Adolescents or the Other Way Round? A Longitudinal Path Analysis.
2016
This study examined whether adolescents’ time spent on sedentary behaviors (academic, technological-based and social-based activities) was a better predictor of academic performance than the reverse. A cohort of 755 adolescents participated in a three-year period study. Structural Equation Modeling techniques were used to test plausible causal hypotheses. Four competing models were analyzed to determine which model best fitted the data. The Best Model was separately tested by gender. The Best Model showed that academic performance was a better predictor of sedentary behaviors than the other way round. It also indicated that students who obtained excellent academic results were more likely t…
Least-squares community extraction in feature-rich networks using similarity data
2021
We explore a doubly-greedy approach to the issue of community detection in feature-rich networks. According to this approach, both the network and feature data are straightforwardly recovered from the underlying unknown non-overlapping communities, supplied with a center in the feature space and intensity weight(s) over the network each. Our least-squares additive criterion allows us to search for communities one-by-one and to find each community by adding entities one by one. A focus of this paper is that the feature-space data part is converted into a similarity matrix format. The similarity/link values can be used in either of two modes: (a) as measured in the same scale so that one may …
A Bayesian unified framework for risk estimation and cluster identification in small area health data analysis.
2020
Many statistical models have been proposed to analyse small area disease data with the aim of describing spatial variation in disease risk. In this paper, we propose a Bayesian hierarchical model that simultaneously allows for risk estimation and cluster identification. Our model formulation assumes that there is an unknown number of risk classes and small areas are assigned to a risk class by means of independent allocation variables. Therefore, areas within each cluster are assumed to share a common risk but they may be geographically separated. The posterior distribution of the parameter representing the number of risk classes is estimated using a novel procedure that combines its prior …
Smart city. Four approaches to the concept of understanding
2020
The paper analyzes the rhetoric of the smart city (SC) concept in order to recognize, categorize, and describe different perspectives of understanding the notion. Four approaches to the SC concept were isolated: three affirmative, and one rejecting. The approaches present a different understanding of the SC and indicate different elements creating urban ‘smartness.’ Despite differences, there is one common goal in every affirmative approach: to improve the quality of urban life. It is achieved through activities covering five dimensions distinguished within affirmative approaches. Together they can serve, i.e.,as a framework for SC case study analyses.
Constitució d'una comunitat social d'investigació amb persones majors des de la responsabilitat social universitària = Constitution of a Social Resea…
2012
Es presenta com s'ha constituït una comunitat social d'investigació (CSI) amb 48 persones majors institucionalitzades des de la responsabilitat social universitària (RSU) i des d'una perspectiva humanista. En aquesta CSI es va valorar el benestar psicològic de les persones institucionalitzades amb mètodes quantitatius i qualitatius, i amb una proposta d'investigació-acció participativa (IAP). S'inicia, així, un procés d'innovació epistemològica, amb escassos antecedents, a l'hora d'investigar i entendre el benestar de les persones majors. Aquesta primera experiència de la CSI aporta observacions sobre els canvis de les dimensions del benestar de Ryff durant el procés d'envelliment dins de l…
