Adicción al cibersexo en función de la orientación sexual: prevalencia y predictores
2020
El cibersexo, una práctica sexual generalizada en la sociedad, puede entrañar ciertos beneficios, aunque también conlleva riesgos (como desarrollar una adicción). Dado que el colectivo LGTBI (Lesbianas, gays, transexuales, bisexuales e intersexuales) lo consume más frecuentemente, el riesgo de adicción también podría ser mayor. Este estudio pretende analizar si la orientación sexual aumentaba el riesgo de consumo adictivo de cibersexo, y si la preferencia por determinadas Actividades Sexuales Online (ASOs) y las motivaciones para su realización explicaban este incremento. A tal fin, 553 personas de entre 18-40 años (54.2% hombres; 36.2% heterosexuales, 36.2% bisexuales, 27.7% homosexuales) …
COVID-19 Drives Consumer Behaviour and Agro-Food Markets towards Healthier and More Sustainable Patterns
2020
This study examines the extant state of research into our understanding of the impact of the coronavirus pandemic in its early stages on food-purchasing behaviour. As such, it includes a summary and categorisation of the findings, extending to consumption preferences worldwide. After the indiscriminate stockpiling of food, which was witnessed in many countries following the implementation of the lockdown, the impact of COVID-19 (COronaVIrus Disease-2019) on consumer habits has inversely varied in function of personal attitudes, individual and household experiences, and characteristics. Specific contexts, and the financial, economic, and logistic nature of these contexts, have also been foun…
Estimación del valor económico de la calidad del agua de un río mediante una doble aproximación: una aplicación de los principios económicos de la Di…
2011
El principal objetivo de la Directiva Marco del Agua de la Unión Europea es logar un “buen estado†de las aguas europeas para el año 2015 mediante una combinación de diferentes medidas. En este estudio, dos métodos de preferencias declaradas, el método de valoración contingente y el método de ordenación contingente, han sido aplicados para obtener la valoración económica de una hipotética mejora de la calidad del agua de un río. La comparación de las dos metodologías muestra que las valoraciones obtenidas con el método de ordenación contingente son considerablemente mayores que las obtenidas con la valoración contingente. Por último, los valores estimados se agregan para obtener una apro…
Optimistic NAUTILUS navigator for multiobjective optimization with costly function evaluations
2022
AbstractWe introduce novel concepts to solve multiobjective optimization problems involving (computationally) expensive function evaluations and propose a new interactive method called O-NAUTILUS. It combines ideas of trade-off free search and navigation (where a decision maker sees changes in objective function values in real time) and extends the NAUTILUS Navigator method to surrogate-assisted optimization. Importantly, it utilizes uncertainty quantification from surrogate models like Kriging or properties like Lipschitz continuity to approximate a so-called optimistic Pareto optimal set. This enables the decision maker to search in unexplored parts of the Pareto optimal set and requires …
Starptautiskās izglītības salīdzinājums studentiem ES un Indijas piedāvājumos: izmaksu kvalitātes analīze
2018
Šajā globalizācijas laikmetā vispasaules augstākās izglītības sistēma ir piedzīvojusi nemainīgas pārmaiņas, tautsaimniecība ir atvērta ne tikai tirdzniecības priekšrocībām, bet arī izglītības nozarēs ir notikusi lielāka liberalizācija. Eiropā un Indijā pasaulē ir vecākās izglītības sistēmas, un pašreizējā scenārijā tās pārvērtē augstāko izglītību attiecībā uz izmaksām, kvalitāti un piekļuvi. Izglītība šīm abām valstīm ir bijusi viena no galvenajām prioritātēm, un valsts augstskolas ir pazīstamas ar kvalitāti un izmaksu garantiju, ar nelielām atšķirībām starp tām, tāpēc tiek mēģināts veikt salīdzinošu pētījumu. Bet ir daži faktori, kas ietekmē indivīda lēmumu pieņemšanu, izvēloties viņu vēla…
Interactive Decision Aids
2011
Decision support systems assist people in making a decision or choosing a course of action in a nonroutine situation that requires judgment (Haubl and Trifts 2000; Kasper 1996). In online webstores, vendors can easily offer highly interactive types of decision support. These co-called interactive decision aids (IDA) “help consumers in making informed purchase decisions amidst the vast availability of online product offerings” (Wang and Benbasat 2009, p. 3). However, the application of IDA is not restricted to purchase decisions. They are general enough to be of use in any kind of choice task where alternatives are known.
Effect of Gaze on Personal Space: A Japanese–German Cross-Cultural Study
2018
In East Asian cultures, people maintain larger interpersonal distances than in European or American cultures. We investigated whether a preference for averted gaze might be responsible for this difference. Typically, when measuring interpersonal distance, participants are asked to maintain eye contact. This request might bias findings due to cultural differences in the interpretation of direct gaze. We had Japanese and German participants adjust preferred interpersonal distance in a standardized laboratory task, using averaged faces with straight-ahead or averted gaze direction. In line with previous findings, Japanese participants preferred overall larger interpersonal distances, and fema…
What Does It Mean to Be Popular in Spain? Mixed-Method Analysis of Popularity as Perceived by Teenagers and Their Teachers
2019
A great part of the research in adolescent popularity is based on sociometric methods, not always distinguishing between social preference (acceptance or likeability) and perceived popularity (visibility or salience), which has practical and theoretical implications. The aim of this work was to analyze the features that a sample of 406 Spanish adolescents (53.2% girls, M = 16.76 years) and their teachers (n = 26, 50% women) associated with perceived popularity. The data analysis established three main themes that categorize perceived popularity: behaviors, developmental traits, and other resources, which include both peer-valued and not valued characteristics. Qualitative and quantitative c…
Morphological similarities between DBM and a microeconomic model of sprawl
2010
JEL classification : C61; C63; D62; R21; R40; International audience; We present a model that simulates the growth of a metropolitan area on a 2D lattice. The model is dynamic and based on microeconomics. Households show preferences for nearby open spaces and neighbourhood density. They compete on the land market. They travel along a road network to access the CBD. A planner ensures the connectedness and maintenance of the road network. The spatial pattern of houses, green spaces and road network self-organises, emerging from agents individualistic decisions. We perform several simulations and vary residential preferences. Our results show morphologies and transition phases that are similar…
