We prove that if GCH holds and τ = 〈κα : α < η 〉 is a sequence of infinite cardinals such that κα ≥ |η | for each α < η, then there is a cardinal-preserving partial order that forces the existence of a scattered Boolean space whose cardinal sequence is τ.

In the past years, many students had problems with their finances, especially their expenses for education. Many of the students are affected by the crisis financially, emotionally, and by their wellbeing. That is why the government provides programs that will help the students with their problems with school expenses, and that is through the Tertiary Education Subsidy (TES) of the Commission on Higher Education (CHED). Further, the primary goal of this study is to explore the TES Grantees' lived experiences, challenges, (...) and coping mechanisms. Furthermore, these are the study's findings: (1) The grantees find the TES very helpful regarding finances that will tackle their academic needs, such as tuition fees and school learning materials. (2) Many students value government assistance that motivates them to maintain their grades. (shrink)

Understanding how people behave when facing hazardous situations, how intrinsic and extrinsic factors influence the risk taking (RT) decision making process and to what extent it is possible to modify their reactions externally, are questions that have long interested academics and society in general. In the spheres of Occupational Safety and Health (OSH), the military, finance and sociology, this topic has multidisciplinary implications because we all constantly face risk taking situations. Researchers have hitherto assessed risk taking profiles by conducting questionnaires (...) prior to and after the presentation of stimuli; however, this can lead to the production of biased, non-realistic, risk taking profiles. This is due to the reflexive nature of choosing an answer in a questionnaire, which is remote from the reactive, emotional and impulsive decision making processes inherent to real, risky situations. One way to address this question is to exploit VR capabilities to generate immersive environments that recreate realistic seeming but simulated hazardous situations. We propose VR as the next-generation tool to study risk taking processes, taking advantage of the big four families of metrics which can provide objective assessment methods with high ecological validity: the real-world risks approach (high presence VR environments triggering real-world reactions), embodied interactions (more natural interactions eliciting natural behaviours), stealth assessment (unnoticed real-time assessments offering efficient behavioural metrics) and physiological real-time measurement (physiological signals avoiding subjective bias). Additionally, VR can provide an invaluable tool, after the assessment phase, to train in skills related to risk taking due to its transferability to real-world situations. (shrink)

The ‘participatory turn’ in science and technology governance has resulted in the growth of initiatives designed to engage lay people in consultation and decision-making on controversial matters. Almost from the start there has been both enthusiasm and serious critique of these exercises, from scholars and activists. The gaps and challenges are well known. In this paper we indicate the limitations of deliberative mechanisms as regards how they cope with familiar forms of people’s engagement with a given matter. We examine how (...) this phenomenon unfolded at the Barcelona Citizen Conference on the Digitalization of Society; a participatory exercise inspired by the model of consensus conferences that took place in 2014 in Barcelona. Our perspective on the topic is inspired by Sociology of Engagements. Focusing on how participants and organizers deal with individual anecdotes, worries and testimonies reported during the conference, the analysis shows how these formats are ignored, externalized, banned and re-formed during deliberations. This phenomenon is seen as supporting a civic-liberal regime of engagement. (shrink)

A new proof style adequate for modal logics is defined from the polynomial ring calculus. The new semantics not only expresses truth conditions of modal formulas by means of polynomials, but also permits to perform deductions through polynomial handling. This paper also investigates relationships among the PRC here defined, the algebraic semantics for modal logics, equational logics, the Dijkstra???Scholten equational-proof style, and rewriting systems. The method proposed is throughly exemplified for S 5, and can be easily extended to other modal (...) logics. (shrink)

Flexibility is a desired characteristic that people must have to adjust to inevitable processes of economic, cultural, and political globalization. Engineering education reform is often used as a justification for changes in curricula, delivery modes, and problem solving that should lead to curriculum integration, modular pedagogies, and systemic reform. Some educators have incorporated the concept in their programs and courses in a variety of ways whereas others have resisted changes to this day. Yet a detailed analysis of the meanings of (...) flexibility, its origins and different forms, along with its challenges and opportunities for engineering education, remains to be done. This article surveys the historical origins of flexibility, identifies different forms of flexibility in engineering education, outlines existing challenges to flexibility-drive educational reform, and provides alternative views to the existing interpretation of flexibility in engineering education.

In this paper we investigated how justifications for price increases are associated with risky decision making and emotional responses. Across two studies with paired lottery choices and sequential decisions, we found that participants presented with a justification for price increases based on increasing demand decided to invest in a comparatively riskier asset more often than participants presented with a justification for price increases based on increasing tax or those presented with no justification at all. We also found that participants presented (...) with justifications for price increases based on increasing demand also reported more arousal displayed higher galvanic skin response than people in the other two justification conditions. Together, these studies provide evidence that the sole increasing demand underlying a price increase of a risky asset can influence the decision to buy it and suggests that emotional activation is involved in such a decision process.

Prosocial behavior and its effects have been analyzed in times of crisis and natural disasters, although never before in the face of such exceptional circumstances as those created by the COVID-19 pandemic. This research analyzes the role of PsB on satisfaction with life in Colombia, considering the negative emotional impact of events that began in February 2020. We conduct an exploratory analysis using a sample of Colombia’s general population with an average age of 44.66 years. Using the Classification Tree technique, (...) we find that engaging in one or more PsBs enhances SWL and decreases the impact of negative emotions such as pessimism, indecisiveness, and irritability that have emerged during the COVID-19 pandemic. These findings are significant because they confirm the importance of life satisfaction as a personal resource for coping with complex situations and provide evidence of the benefits of PsB on one’s wellbeing.

The initial stage for the discussion is the distinction between bona fide and fiat objects drawn by Barry Smith and collaborators in the context of formal ontology. This paper aims at both producing a rationale for introducing a hitherto unrecognized kind of object—here called ‘Interactive Fiat Objects’ (IFOs)—into the ontology of objects, and casting light on the relationship between embodied cognition and interactive ontology with the aid of the concepts of affordance and ad hoc category. I conclude that IFOs are (...) similar to fiat objects, affordances and ad hoc categories in a number of ways, yet they differ from these in important respects. Interaction is key to understanding the existence and peculiarities of IFOs. By adopting an embodied perspective on cognition, we can enrich our ontological typologies and highlight relevant features of our physical and symbolic environment that are otherwise overlooked. This should improve our understanding of object ontology and persuade us to include IFOs in our metaphysical inventories. (shrink)

Philosophers, psychologists, and economists have reached the consensus that one can use two different kinds of regulation to achieve self-control. Synchronic regulation uses willpower to resist current temptation. Diachronic regulation implements a plan to avoid future temptation. Yet this consensus may rest on contaminated intuitions. Specifically, agents typically use willpower (synchronic regulation) to achieve their plans to avoid temptation (diachronic regulation). So even if cases of diachronic regulation seem to involve self-control, this may be because they are contaminated by synchronic (...) regulation. We therefore developed a novel multifactorial method to disentangle synchronic and diachronic regulation. Using this method, we find that ordinary usage assumes that only synchronic––not diachronic––regulation counts as self-control. We find this pattern across four experiments involving different kinds of temptation, as well as a paradigmatic case of diachronic regulation based on the classic story of Odysseus and the Sirens. Our final experiment finds that self-control in a diachronic case depends on whether the agent uses synchronic regulation at two moments: when she (1) initiates and (2) follows-through on a plan to resist temptation. Taken together, our results strongly suggest that synchronic regulation is the sole difference maker in the folk concept of self-control. (shrink)

RESUMENLa teoría representacional de la mente, basada en el concepto de representación, ha sido muy criticada, especialmente por recientes enfoques en la ciencia cognitiva, provenientes de la Biología y la Inteligencia Artificial. En este trabajo me centro especialmente en el punto de vista de Francisco Varela, quien sugiere la exclusión del término representación en la explicación de los sistemas cognitivos. Muestro que ello no es necesario, y que hay razones para hablar de representaciones en la relación que tenemos con el (...) mundo en términos de conocimiento, por tanto, el antirrepresentacionalismo de Varela es inadecuado. En ese sentido me parece más afortunada la apreciación que hacen de la ciencia cognitiva y la filosofía de la mente Andy Clark y Pascual Martínez-Freire, y ésta es la postura que defenderé en contra de Varela.PALABRAS CLAVEMENTE, REPRESENTACIÓN, COGNITIVISMO, CONDUCTA, SISTEMAABSTRACTThe representational theory of the mind, based on the concept of representation, has been very criticized, specially by recent approaches to cognitive science, originated from Biology and Artificial Intelligence.

In the present paper we study the framework of additive utility theory, obtaining new results derived from a concurrence of algebraic and topological techniques. Such techniques lean on the concept of a connected topological totally ordered semigroup. We achieve a general result concerning the existence of continuous and additive utility functions on completely preordered sets endowed with a binary operation ``+'', not necessarily being commutative or associative. In the final part of the paper we get some applications to expected utility (...) theory, and a representation theorem for a class of complete preorders on a quite general family of real mixture spaces.

This paper explores the concept of a social evaluation functional in the case of an arbitrary set of alternatives. In the first part, a characterization of projective social evaluations functionals is shown whenever the common restricted domain is the set of all bounded utility functions equipped with the supremum norm topology. The result makes a crucial use, among others, of a continuity axiom. In the second part, a comparison meaningful property is introduced for a social evaluation functional which allows us (...) for obtaining a more general result with no continuity requirements. Finally, an impossibility theorem, which is reminiscent of that is obtained by Chichilnisky in (Q J Econ 97:337–352, 1982) but without using topological conditions, is offered. (shrink)

Many philosophers and scientists rightly take hallucinations to be phenomena that challenge in a most pressing way our theories of perception and cognition, and epistemology in general. However, very few challenge the received views on the hallucinatory experience and even fewer critically delve into the subject with both breadth and depth. There are all kinds of problems concerning hallucinations—including conceptual, methodological, and empirical issues—that call for a multilevel analysis and an interdisciplinary approach which in turn provide the detail and scope (...) that the subject demands. In this paper, I present and briefly discuss four interrelated problems: (1) definitions, (2) dependence on perception, (3) two views on hallucinations, and (4) methodology. Neglect or underestimation of these problems, among other things, continue to prevent a proper understanding of the concept and the corresponding experience, giving rise to misconceptions and even plain myths on the subject. Hallucinations do occur; but in order to productively investigate them (for whatever end), we first need to get clear on the concept and develop a suitable epistemological framework for their analysis.

This paper analyzes the process of perceptual recalibration (PR) in light of two cases of technologically-mediated cognition: sensory substitution and perceptual modification. We hold that PR is a very useful concept - perhaps necessary - for explaining the adaptive capacity that natural perceptive systems display as they respond to functional demands from the environment. We also survey critically related issues, such as the role of learning, training, and nervous system plasticity in the recalibrating process. Attention is given to the interaction (...) between technology and cognition, and the case of epistemic prostheses is presented as an illustration. Finally, we address the following theoretical issues: (1) the dynamic character of spatial perception; (2) the role of functional demands in perception; (3) the nature and interaction of sensory modalities. We aim to show that these issues may be addressed empirically and conceptually - hence, the usefulness of sensory-substitution and perceptual-modification studies in the analysis of perception, technologically-mediated cognition, and cognition in general.

Metallothioneins (MTs) are ubiquitous proteins with the capacity to bind heavy metal ions (mainly Cd, Zn or Cu), and they have been found in animals, plants, eukaryotic and prokaryotic micro‐organisms. We have carried out a comparative analysis of ciliate MTs (Tetrahymena species) to well‐known MTs from other organisms, discussing their exclusive features, such as the presence of aromatic amino acid residues and almost exclusive cysteine clusters (CCC) present in cadmium‐binding metallothioneins (CdMTs), higher heavy metal‐MT stoichiometry values, and a strictly conserved (...) modular–submodular structure. Based on this last feature and an extensive gene duplication, we propose a possible model for the evolutionary history of T. thermophila MTs. We also suggest possible functions for these MTs from consideration of their differential gene expressions and discuss the potential use of these proteins and/or their gene promoters for designing molecular or whole‐cell biosensors for a fast detection of heavy metals in diverse polluted ecosystems.

Although it is an increasingly popular assumption that leader mindfulness may positively affect leader behaviors and, in turn, employee outcomes, to date, little empirical evidence supports this view. Against this backdrop, the present research seeks to develop and test a serial mediation model of leader mindfulness. Specifically, we propose that leader mindfulness enhances employee performance and that this relationship is explained by increased leader procedural justice enactment and, subsequently, reduced employees’ emotional exhaustion. We conducted three studies to test this model. (...) Study 1 involved employees from a wide range of organizations in the USA. Study 2 used a sample of leaders and employees from China and measured our model variables at three different points in time. Both studies provide consistent support for our hypotheses. Finally, Study 3 involved a laboratory experiment in which 62 senior executives were assigned to either a mindfulness induction or to a control condition. Again, results revealed a significant and positive link between leader mindfulness and leader procedural justice enactment. In sum, these findings expand our understanding of mindfulness to the domain of leadership, a key area of organizational research. Moreover, they complement prior studies by showing that mindfulness dynamics go beyond intrapersonal effects but also influence the attitudes and behaviors of others. We discuss our findings in light of their contributions to the mindfulness, ethics, and leadership literatures and point out implications for practice. (shrink)

Behavioral interventions have shown promising neuroprotective effects, but the cascade of molecular, brain and behavioral changes involved in these benefits remains poorly understood. Projecte Moviment is a 12-week multi-domain, single-blind, proof-of-concept randomized controlled trial examining the cognitive effect and underlying mechanisms of an aerobic exercise, computerized cognitive training and a combined groups compared to a waitlist control group. Adherence was > 80% for 82/109 participants recruited. In this study we report intervention-related changes in plasma biomarkers and structural-MRI and how they (...) related to changes in physical activity and individual variables and their potential role as mediators in the cognitive changes. Our results show that although there were no significant changes in molecular biomarker concentrations in any intervention group, changes in ICAM-1 and SDF1-α were negatively associated with changes in physical activity outcomes in AE and COMB groups. Brain volume changes were found in the CCT showing a significant increase in precuneus volume. Sex moderated the brain volume change in the AE and COMB groups, suggesting that men may benefit more than women. Changes in molecular biomarkers and brain volumes did not significantly mediate the cognitive-related benefits found previously for any group. This study shows crucial initial molecular and brain volume changes related to lifestyle interventions at early stages and highlights the value of examining activity parameters, individual difference characteristics and using a multi-level analysis approach to address these questions.

Gilbert Ryle claimed that intelligent actions and activities are not merely the external signs of inner mental workings but rather that such actions and activities are the workings of the mind itself. In this thesis I propose an interpretation and defence of sich claim, against a common an, in my view, mistaken way of understanding Ryle's position. In chapter [1]. I introduce the argumentative thread of this thesis and a more detailed overview of the chapters. In chapter [2], I criticise (...) Stanley and Williamson's understanding of Ryle's argument and position. In chapters [3]-[5] I examine Ryle's position and provide a way of understanding his view against what I take his main opponent, INTELLECTUALISM, to be. Chapter [6] offers an argument against INTELLECTUALISM as a way of motivating a Rylean account intelligent actions and activities. I conclude in chapter [7] with a response to purported counter-examples to the view I propose. (shrink)

La psychologie phénoménologique sartrienne, qui s?attèle à repenser la mé­thode psychologique classique, inopérante et cernée de préjugés et d? a priori chargés, fait de l?émotion un de ses sujets de prédilection.

L?émotion deviendra finalement, dans la psychana­lyse existentielle appliquée, le lieu même de la construction de soi dans l?enfance en ce que le choix originel se crée sur base d?un affect en situation qui orientera toute la destinée sociale et affective de l?individu considéré.

BackgroundDistorted gambling-related cognitions are tightly related to gambling problems, and are one of the main targets of treatment for disordered gambling, but their etiology remains uncertain. Although folk wisdom and some theoretical approaches have linked them to lower domain-general reasoning abilities, evidence regarding that relationship remains unconvincing.MethodIn the present cross-sectional study, the relationship between probabilistic/abstract reasoning, as measured by the Berlin Numeracy Test, and the Matrices Test, respectively, and the five dimensions of the Gambling-Related Cognitions Scale, was tested in a (...) sample of 77 patients with gambling disorder and 58 individuals without gambling problems.Results and interpretationNeither BNT nor matrices scores were significantly related to gambling-related cognitions, according to frequentist analyses, performed both considering and disregarding group in the models. Correlation Bayesian analyses largely supported the null hypothesis, i.e., the absence of relationships between the measures of interest. This pattern or results reinforces the idea that distorted cognitions do not originate in a general lack of understanding of probability or low fluid intelligence, but probably result from motivated reasoning.
