Comparing reference point based interactive multiobjective optimization methods without a human decision maker
2022
AbstractInteractive multiobjective optimization methods have proven promising in solving optimization problems with conflicting objectives since they iteratively incorporate preference information of a decision maker in the search for the most preferred solution. To find the appropriate interactive method for various needs involves analysis of the strengths and weaknesses. However, extensive analysis with human decision makers may be too costly and for that reason, we propose an artificial decision maker to compare a class of popular interactive multiobjective optimization methods, i.e., reference point based methods. Without involving any human decision makers, the artificial decision make…
Audience experience of commercial videos and feature length films : are they universal or culturally mediated?
2017
Audiovisual contents constitute one of the most common ways of communicating information. However, audiovisual products are difficult to study because they integrate a lot of complex communication and artistic elements. Meaning and emotions are conveyed by combining film elements but also narrative elements, music and other audio aspects, which unfold over time and can be used to impact the audiences. Here, the user experience approach is taken to try to understand the relation between the video’s elements and the emotions produced in the audience. Emotions are understood within an appraisal framework where elements of the audiovisual format and content are integrated in memory with previou…
Lessons learned on student engagement from the nature of pervasive socio‐digital interests and related network participation of adolescents
2021
The rise of modern socio-digital technologies has fundamentally changed the everyday environments in which young people communicate with each other and cultivate interests. To gain a more sophisticated understanding of this phenomenon, this study provides in-depth, qualitative insights into adolescents’ experiences of their socio-digital developmental ecologies. The 15 interview participants were recruited based on a previously conducted questionnaire. The semi-structured theme interview addressed the socio-digital aspects of the participants’ interest-driven behaviours and related networks with the aid of participant-generated egocentric maps. The data not only qualitatively enrich the pic…
Il diritto non scritto nel sistema della Convenzione europea dei diritti umani
2016
Il lavoro si occupa dei rapporti tra diritto internazionale generale e sistema della Cedu, affrontando in particolare il problema di capire se la Corte edu abbia fatto ricorso al modello tradizionalmente usato nella giurisprudenza internazionale per stabilire condizioni e modalità di funzionamento delle norme generali nel sistema o se abbia elaborato una concezione un modello autonomo. This paper discusses the relationship between customary international law and the ECHR. The focus is the question whether this problem has been handled by the European Court of Human Rights through the model of relationship between customary law and treaty law which is commonly used by international judges an…
Quantitative Runge Approximation and Inverse Problems
2017
In this short note we provide a quantitative version of the classical Runge approximation property for second order elliptic operators. This relies on quantitative unique continuation results and duality arguments. We show that these estimates are essentially optimal. As a model application we provide a new proof of the result from \cite{F07}, \cite{AK12} on stability for the Calder\'on problem with local data.
Shaping 1,2,4-Triazolium Fluorinated Ionic Liquid Crystals
2023
The synthesis and thermotropic behaviour of some di-alkyloxy-phenyl-1,2,4-triazolium trifluoromethane-sulfonate salts bearing a seven-carbon atom perfluoroalkyl chain on the cation is herein described. The fluorinated salts presenting a 1,2,4-triazole as a core and differing in the length of two alkyloxy chains on the phenyl ring demonstrated a typical liquid crystalline behaviour. The mesomorphic properties of this set of salts were studied by differential scanning calorimetry and polarized optical microscopy. The thermotropic properties are discussed on the grounds of the tuneable structures of the salts. The results showed the existence of a monotropic, columnar, liquid crystalline phase…
A strategic approach for the discounted Shapley values
2014
The family of discounted Shapley values is analyzed for cooperative games in coalitional form. We consider the bargaining protocol of the alternating random proposer introduced in Hart and Mas-Colell (Econometrica 64:357–380, 1996). We demonstrate that the discounted Shapley values arise as the expected payoffs associated with the bargaining equilibria when a time discount factor is considered. In a second model, we replace the time cost with the probability that the game ends without agreements. This model also implements these values in transferable utility games, moreover, the model implements the \(\alpha \)-consistent values in the nontransferable utility setting.
Gestión empresarial y dinámica laboral en España
2015
El objetivo del presente artículo es plantear una serie de reflexiones sobre la dinámica labo- ral reciente en la economía española bajo el enfoque analítico de la segmentación laboral. Desde esta perspectiva, la situación y problemas del mercado laboral se explican por un conjunto de factores relacionados con las prácticas de gestión empresarial y no tanto por la regulación que limita la competencia en el mercado o las modalidades contractuales. Nues- tra conclusión es que es necesario superar el marco analítico restringido del enfoque econó- mico convencional e introducir otras dimensiones, que van más allá del mercado, para una mejor compresión de los problemas laborales. En este sentido…
The People’s Assembly: Testing the Collaborative (e)-Democracy
2020
This paper aims to critically analyse the Estonian People’s Assembly (EPA), a crowdsourcing initiative carried out from 2013 to 2014. During the project, citizens could participate in decision-making and make proposals for laws and policies on a dedicated web-platform. Additionally, some people were invited for a traditional off-line debate. In that way, the project combined virtual communication tools with traditional discussion to apply the principles of collaborative e-democracy, in which governmental stakeholders and non-governmental stakeholders (such as local communities) join in a deliberative debate. The purpose of this paper is to observe, both, gains and problems of this crowdsour…
Students' abilities to evaluate the credibility of online texts: The role of internet‐specific epistemic justifications
2021
Previous evaluation studies have rarely used authentic online texts and investigated upper secondary school students' use of evaluation criteria and deep reasoning. The associations between internet-specific epistemic justifications for knowing and credibility evaluation of online texts are not yet fully understood among adolescents. This study investigated upper secondary school students' (N = 372) abilities to evaluate self-selected authentic online texts and the role of internet-specific epistemic justifications in students' evaluation performance when solving a health-related information problem. Students selected three texts with Google Custom Search Engine and evaluated their credibil…
