Auto-observación en adolescentes: los problemas de la escala de auto-observación de Snyder en poblaciones no adultas

Los objetivos de la presente investigación fueron examinar las diferencias en la variable de personalidad auto -observación (AO) entre adolescentes y jóvenes adultos, y extender la investigación sobre su validez de constructo a la población de adolescentes. Con este fin, se administro la Escala de A0 de Snyder a una muestra de 124 adolescentes y a otra de 156 universitarios. Los adolescentes también completaron el Cuestionario de Personalidad para Adolescentes (HSPQ) de CatteN y la Escala de Autoconcepto (EA) de Morales. Los resultados indicaron que aunque 1os adolescentes no diferian de los universitarios en la puntuación total en AO, sí mostraban puntuaciones mayores en uno de los factores de AO, orientación hacia los demás, y menores en otros dos: extraversión y actuación. Las correlaciones halladas en la muestra de adolescentes entre los factores de A0 y entre éstos y las variables de extraversión (medida por el HSPQ) y de autoestima (medida por la EA) sugieren una falta de congruencia entre la definición del constructo AO y lo que la Escala de AO realmente parece medir

Indicadores de actividad cultural y potencial creativo en Portugal: estudio regional para NUT 3

The creative economy has been the subject of increasing interest in recent years, both in the area of cultural economics as well as in economic development studies and the analysis of spatial disparities. The underlying notion is to consider creative capital as a production factor linked to talent, technological innovation and initiative, which may shape part of an area or region’s economic flows, replacing merely physical production factors. Clearly, many of the activities to emerge from creative capital are based mainly on culture and cultural activities. Yet, their ultimate goal is not to produce purely artistic artefacts aside from the market but to create marketable prototypes which are differentiated due to their design and innovative nature. This is why, today, creative activities might have a greater impact on economic development than talent, perceived in the conventional sense. Based on these considerations, the current work seeks to explore the territorial distribution of cultural activities and creativity in Portugal and to ascertain the relationship with the level of economic development. This involves defining the cultural and creative sector and its main components, for which purpose we follow the definition of cultural sector from Maheus (2010) and we draw on R. Florida’s (2002) widely embraced factors; talent, technology, and tolerance. The level of territorial disaggregation is NUTS 3. The technique applied is based on multivariate statistical analysis, essentially, factorial analysis to construct synthetic indicators for creativity and development; and cluster analysis to determine homogeneous areas in the resulting distribution. We build partial indicators from the main conceptual branches of the cultural sector and creativity and we also estimate a new global synthetic indicator based on the main components obtained before by factorial analysis. As expected, the most salient preliminary findings to emerge from the study point to a concentration of creative activities mainly in the areas around Lisbon and Oporto, there also being agglomeration factors around university cities and other places whichinfo:eu-repo/semantics/publishedVersio

Enhanced Accuracy of Continuous Glucose Monitoring during Exercise through Physical Activity Tracking Integration

[EN] Current Continuous Glucose Monitors (CGM) exhibit increased estimation error during periods of aerobic physical activity. The use of readily-available exercise monitoring devices opens new possibilities for accuracy enhancement during these periods. The viability of an array of physical activity signals provided by three different wearable devices was considered. Linear regression models were used in this work to evaluate the correction capabilities of each of the wearable signals and propose a model for CGM correction during exercise. A simple two-input model can reduce CGM error during physical activity (17.46% vs. 13.8%, p < 0.005) to the magnitude of the baseline error level (13.61%). The CGM error is not worsened in periods without physical activity. The signals identified as optimal inputs for the model are Mets (Metabolic Equivalent of Tasks) from the Fitbit Charge HR device, which is a normalized measurement of energy expenditure, and the skin temperature reading provided by the Microsoft Band 2 device. A simpler one-input model using only Mets is also viable for a more immediate implementation of this correction into market devices.This work was supported by the Spanish Ministry of Economy, Industry and Competitiveness (MINECO) (Grant Number DPI2016-78831-C2-1-R), the European Union (FEDER funds), and the Vicerectorate of Research, Innovation and Technology Transference from the Universitat Politecnica de Valencia (Grant Number PAID-06-18).

erfiles decisionales de jugadores y jugadoras de voleibol de diferente nivel de pericia. (Decisional profiles of volleyball players of different expertise level.)

<p><strong>Resumen</strong></p><p align="justify">La toma de decisiones por parte de los deportistas se viene estudiando como un tipo de habilidad cognitiva. En este estudio se parte de una perspectiva motivacional y emocional de la toma de decisiones en el deporte, que ha recibido una menor atenci&oacute;n en la literatura. Se aplica el Cuestionario de Estilos de Toma de Decisi&oacute;n en el Deporte-CETD (Ruiz y Graupera, 2005) que eval&uacute;a tres escalas: Competencia Decisional Percibida, Ansiedad y Agobio al Decidir y Compromiso en el Aprendizaje Decisional. Se toma una muestra de 121 jugadoras (76) y jugadores (45) de voleibol de diferente nivel de pericia deportiva: auton&oacute;mico, nacional e internacional. Los resultados muestran que las escalas del cuestionario tienen una buena fiabilidad cuando se aplican a muestras mono-deportivas. Las jugadoras y jugadores de voleibol tienen un perfil decisional muy similar (no se encuentran diferencias significativas), con una moderada percepci&oacute;n de competencia, baja ansiedad y alto compromiso (perfil en V). Seg&uacute;n aumenta el nivel deportivo se incrementa moderadamente el compromiso y la percepci&oacute;n de competencia, mientras que decrece considerablemente la ansiedad ante la toma de decisiones. Como consecuencia el perfil en V del nivel internacional es considerablemente m&aacute;s cerrado que el de los niveles deportivos inferiores. </p><p><strong>Palabras clave</strong>: ansiedad; competencia percibida; decisi&oacute;n; deporte colectivo; pericia deportiva. </p><p><strong>Abstract</strong> </p><p align="justify">Decision making in sport has been studied as a kind of cognitive skill. This study has been developed from a motivacional and emotional point of view and this question has received little attention in the scientific literature. It was applied the Decision Making Style Questionnaire-CETD (Ruiz y Graupera, 2005) that assess three scales: Perceived Decisional Competence, Anxiety and Strain to Decide and Commitment for learning how to decide. One hundred and twenty one voleyball players participated (76 female and 45 male) of differente level of expertise: State, National and International. Results showed that the scales of this questionnaire had good reliability when it was applied to specific sport samples. Male and female volleyball players had a similar decisional profile (there were no significant differences), with a moderate selfperception of decisional competence, low level of anxiety and high commitment (V profile). As competence increased, moderately increased the level of commitment and selfperception of decisional competence, too, and decreased the level of anxiety. As a consequence, the decisional profile of the International Group was very different from the rest of the two groups of lower competence. </p><p><strong>Key words</strong>: anxiety; perceived competence; decision; team sport; sport expertise.</p

Artificial Pancreas System With Unannounced Meals Based on a Disturbance Observer and Feedforward Compensation

The main limitations are the delays introduced by the subcutaneous insulin pharmacokinetics and the glucose sensor, which typically leads to insulin overdelivery. Current solutions reported in the literature typically resort to meal announcement, which requires patient intervention. In this brief, a disturbance observer (DOB) is used to estimate the effect of unannounced meals, and the insulin pharmacokinetics is taken into account by means of a feedforward compensator. The proposed strategy is validated in silico with the UVa/Padova metabolic simulator. It is demonstrated how the DOB successfully estimates and counteracts not only the effect of meals but also the sudden drops in the glucose levels that may lead to hypoglycemia. For unannounced meals, results show a median time-in-range of 80% in a 30-day scenario with high carbohydrate content and large intrasubject variability. Optionally, users may decide to announce meals. In this case, considering severe bolus mismatch due to carbohydrate counting errors, the median time-in-range is increased up to 88%. In every case, hypoglycemia is avoided.This work was supported in part by the Ministerio de Economia y Competitividad under Grant DPI2016-78831-C2-1-R and in part by the European Union through FEDER Funds.Sanz Diaz, R.; García Gil, PJ.; Diez, J.; Bondía Company, J.

Acoustic, myoelectric, and aerodynamic parameters of euphonic and dysphonic voices: a systematic review of clinical studies

At present, there is no clinical consensus on the concept of normal and dysphonic voices. For many years, the establishment of a consensus on the terminology related to normal and pathological voices has been studied, in order to facilitate the communication between professionals in the field of the voice. Aim: systematically review the literature to compare and learn more precisely the measurable and objective characteristics of the acoustic, aerodynamic and surface electromyographic parameters of the normal and dysphonic voices. Methods: The PRISMA 2020 methodology was used as a review protocol together with the PICO procedure to answer the research question through six databases. Results: In total, 467 articles were found. After duplicate records were removed from the selection, the inclusion and exclusion criteria were applied and 19 articles were eligible. A qualitative synthesis of the included studies is presented in terms of their methodology and results. Conclusions: Studying the acoustic, aerodynamic, and electromyographic parameters with more precision, in both normal and dysphonic voices, will allow health professionals working in the field of voice (speech therapy, otorhinolaryngology, phoniatrics, etc.) to establish a diagnostic and detailed consensus of the vocal pathology, enhancing the communication and generalization of results worldwide

Prokaryotic diversity and dynamics in a full-scale municipal solid waste anaerobic reactor from start-up to steady-state conditions

AbstractThe prokaryotic diversity of an anaerobic reactor for the treatment of municipal solid waste was investigated over the course of 2years with the use of 16S rDNA-targeted molecular approaches. The fermentative Bacteroidetes and Firmicutes predominated, and Proteobacteria, Actinobacteria, Tenericutes and the candidate division WWE1 were also identified. Methane production was dominated by the hydrogenotrophic Methanomicrobiales (Methanoculleus sp.) and their syntrophic association with acetate-utilizing and propionate-oxidizing bacteria. qPCR demonstrated the predominance of the hydrogenotrophic over aceticlastic Methanosarcinaceae (Methanosarcina sp. and Methanimicrococcus sp.), and Methanosaetaceae (Methanosaeta sp.) were measured in low numbers in the reactor. According to the FISH and CARD-FISH analyses, Bacteria and Archaea accounted for 85% and 15% of the cells, respectively. Different cell counts for these domains were obtained by qPCR versus FISH analyses. The use of several molecular tools increases our knowledge of the prokaryotic community dynamics from start-up to steady-state conditions in a full-scale MSW reactor
