Recommending the identity of bidders in public procurement auctions has a significant impact in many areas of public procurement, but it has not yet been studied in depth. A bidders recommender would be a very beneficial tool because a supplier can search appropriate tenders and, vice versa, a public procurement agency can discover automatically unknown companies which are suitable for its tender. This paper develops a pioneering algorithm to recommend potential bidders using a machine learning method, particularly a random forest (...) classifier. The bidders recommender is described theoretically, so it can be implemented or adapted to any particular situation. It has been successfully validated with a case study: an actual Spanish tender dataset which has 102,087 tenders from 2014 to 2020 and a company dataset which has 1,353,213 Spanish companies. Quantitative, graphical, and statistical descriptions of both datasets are presented. The results of the case study were satisfactory: the winning bidding company is within the recommended companies group, from 24% to 38% of the tenders, according to different test conditions and scenarios.

This paper concludes a special feature of Sustainability Science that explores a broad range of social value theoretical traditions, such as religious studies, social psychology, indigenous knowledge, economics, sociology, and philosophy. We introduce a novel transdisciplinary conceptual framework that revolves around concepts of 'lenses' and 'tensions' to help navigate value diversity. First, we consider the notion of lenses: perspectives on value and valuation along diverse dimensions that describe what values focus on, how their sociality is envisioned, and what epistemic and (...) procedural assumptions are made. We characterise fourteen of such dimensions. This provides a foundation for exploration of seven areas of tension, between: (1) the values of individuals vs collectives; (2) values as discrete and held vs embedded and constructed; (3) value as static or changeable; (4) valuation as descriptive vs normative and transformative; (5) social vs relational values; (6) different rationalities and their relation to value integration; (7) degrees of acknowledgment of the role of power in navigating value conflicts. In doing so, we embrace the 'mess' of diversity, yet also provide a framework to organise this mess and support and encourage active transdisciplinary collaboration. We identify key research areas where such collaborations can be harnessed for sustainability transformation. Here it is crucial to understand how certain social value lenses are privileged over others and build capacity in decision-making for understanding and drawing on multiple value, epistemic and procedural lenses.

Previous research suggests that free will beliefs and moral responsibility beliefs are strongly linked, yet ultimately distinct. Unfortunately, the most common measure of free will beliefs, the free will subscale (FWS) of the Free Will and Determinism Plus, seems to confound free will beliefs and moral responsibility beliefs. Thus, the present research (1,700 participants across two studies) details the development of a 2-factor FWS – the FWS-II – that divides the FWS into a free will subscale and a moral responsibility (...) subscale. The FWS-II showed good fit compared to standard fit thresholds and superior fit compared to the original FWS. The moral responsibility subscale was moderately correlated with general punitive attitudes and specific punitive assignments, even when controlling for the free will subscale. Conversely, the free will subscale was moderately correlated with conservativism and religiosity, even when controlling for the moral responsibility subscale. These results provide evidence that the FWS is better suited – psychometrically, theoretically, and practically – as a 2-factor measure of free will beliefs and moral responsibility beliefs than as a 1-factor measure of free will beliefs.

What do we quantify when we attempt to quantify semiotic systems and theories? How sound are potential quantifications in terms of interpretive values within some varieties of semiotic theory? We will make a distinction between formalization and quantification in order to understand what to quantify, how to quantify it and why quantification may be a desirable outcome for semiotic theory. The implications of this stance may be relevant and philosophically interesting in light of the naturalized project of biosemiotics. In this (...) paper we will try to understand some ideas behind the rationale of formalizing and quantifying semiotic phenomena and discuss whether this possibility can or should map to functionalized descriptions of semiosis and the sign.

Video games are ideal platforms for the study of skill acquisition for a variety of reasons. However, our understanding of the development of skill and the cognitive representations that support skilled performance can be limited by a focus on game scores. We present an alternative approach to the study of skill acquisition in video games based on the tools of the Expert Performance Approach. Our investigation was motivated by a detailed analysis of the behaviors responsible for the superior performance of (...) one of the highest scoring players of the video game Space Fortress. This analysis revealed how certain behaviors contributed to his exceptional performance. In this study, we recruited a participant for a similar training regimen, but we collected concurrent and retrospective verbal protocol data throughout training. Protocol analysis revealed insights into strategies, errors, mental representations, and shifting game priorities. We argue that these insights into the developing representations that guided skilled performance could only easily have been derived from the tools of the Expert Performance Approach. We propose that the described approach could be applied to understand performance and skill acquisition in many different video games and help reveal mechanisms of transfer from gameplay to other measures of laboratory and real-world performance.

In the paper we obtain a new characterization of the BCK-algebras which are subdirect product of BCK-chains. We give an axiomatic algebraizable extension of the BCK-calculus, by means of a recursively enumerable set of axioms, such that its equivalent algebraic semantics is definitionally equivalent to the quasivariety of BCK-algebras generated by the BCK-chains. We propose the concept of "linearization of a system" and we give some examples.

In this paper an algebraic version for temporal algebras of the logical filtrations for modal and temporal logics is analysed. A structure theorem for free temporal algebras and also some results with regard to the variety of temporal algebras are obtained.

In this paper the structure of pretemporal algebra is used to study some aspects of temporal algebras and modal algebras. The paper contains a computational approach to finite temporal algebras and a general splitting theorem for finite temporal algebras.

This handbook offers a deep analysis of the main forms of legal reasoning and argumentation from both a logical-philosophical and legal perspective. These forms are covered in an exhaustive and critical fashion, and the handbook accordingly divides in three parts: the first one introduces and discusses the basic concepts of practical reasoning. The second one discusses the main general forms of reasoning and argumentation relevant for legal discourse. The third one looks at their application in law as well as at (...) the different areas of legal reasoning. The handbook’s division in three parts reflects its conceptual architecture, since legal reasoning and argumentation are considered in relation to the more general types of reasoning. (shrink)

Integrated approaches in the ethical decision-making (EDM) and practically wise decision-making literature are emerging as alternative perspectives to management theories that conceptualize decision-making in a rationalist and value-free manner. However, more dialogue between both perspectives and qualitative research that applies them is required. In addition, there is a need for empirical analysis on business engagement in the face of grand challenges in developing countries. This paper proposes an integrated practically wise EDM framework to study how Colombian councilors who, in 2013, (...) voted for or against the merger between the Colombian state-owned company UNE and the Swedish multinational Millicom interpret this decision and its public impact. Qualitative semi-structured interviews were conducted with a voluntary sample of 18 of 21 councilors. Supporters of the UNE-Millicom merger expressed open-mindedness, seeing the merger as a means to achieve justice. On the contrary, the merger’s opponents expressed circumspection, doubting that Millicom’s intentions really leaned toward justice. We conclude that practical wisdom—embodied by both supporters and detractors—fosters an understanding of EDM beyond what leaders should not do. It also includes a democratic and balanced deliberation on what leaders think they should do to promote the common good. (shrink)

Sport is an emotional experience. Studies have shown that high emotional intelligence (EI) is associated with better sports performance, though different aspects of sports experience and their relationship with EI are still unclear. This study examined the possible relationships between sports experience and EI dimensions of undergraduate athletes. Likewise, according to the differences described in the literature between men and women, the secondary aim was to identify the possible relationship between EI and sports experience in both subgroups. A total of (...) 1784 [712 men (39.9%), 1072 women (60.1%); mean age = 21.3 years, SD = 4.2)] undergraduate athletes completed the Trait Meta Mood Scale and a sports experience questionnaire. Comparisons between groups were performed using Mann–Whitney-Uand H-Kruskal–Wallis tests and correlations between variables were analyzed using Spearman correlation. We found that the number of different sports practiced and the number of years practicing sports were positively associated with emotional repair (ER). However, the number of years practicing sports was negatively associated with emotional attention (EA). Male athletes who trained more and had a higher competitive level were more likely to show higher ER. In any case, it is necessary to take into account that all the associations were weak. Our study suggested that athletes tend to attend to and value their feelings and use positive thinking to repair their negative moods. (shrink)
