This paper reflects on quality assessment and performance evaluation in higher education, namely by analysing the insufficient link between those two aspects. We start by reviewing the current state of the art regarding different processes and mechanisms of quality assessment and performance evaluation and discuss some of the major issues regarding the implementation of some of them. In particular, we analyse the current limitations regarding data collected, available and publicised on the performance of HEIs and the problems those limitations bring (...) to a fair evaluation of higher education. Through this analysis we intend to contribute to a better understanding of the mechanisms of evaluation in higher education and the way these may lead to the promotion of better quality assessment practices and institutional management.

Introduction: The aim of this review was to systematically synthesize the published literature describing the psychological and behavioral correlates of recreational running in adults, defined as running for leisure, with or without a competitive component.Methods: Quantitative research published in peer-reviewed journals until January 2021 were included. Studies were identified through MEDLINE, PsycINFO, SPORTDiscus, and Web of Science and were included in this review if they were aimed at recreational running, included general adult samples, and assessed psychological or behavioral correlates of (...) recreational running.Results: Fifty-six articles reporting 58 studies met the eligibility criteria and were included. There were 27 cross-sectional studies, 12 longitudinal studies, and 19 trials. Twenty-eight studies assessed antecedents of running behavior, and 25 studies used running behavior as treatment or predictor of a given effect or outcome. Four studies examined both predictors and outcomes of running. Thirty-one studies showed poor quality, while 20 had fair and 7 good quality. Motives were the most frequently studied antecedent of running behavior, and results suggest that the highest-ranked or more prevalent motives were physical health, psychological motives, and personal achievement. Additionally, perceived control, attitude toward running, intention and subjective norms, self-efficacy, and social support may have also played a role in the adoption of recreational running. Moreover, improvements in mood and well-being were the most frequently reported positive outcomes of running. Reductions in depression, anxiety, and stress were also reported in included studies.Discussion: To our knowledge, this is the first systematic review on this topic. The identification of behavioral and psychological correlates of recreational running across populations can contribute to inform and guide a public policy agenda, focused on helping people sustain regular physical activity, through a modality they have chosen and appear to enjoy.Systematic Review Registration:https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=68954, identifier: CRD42017068954.

IntroductionTranscranial magnetic stimulation is a consolidated procedure for the treatment of depression, with several meta-analyses demonstrating its efficacy. Theta-burst stimulation is a modification of TMS with similar efficacy and shorter session duration. The geriatric population has many comorbidities and a high prevalence of depression, but few clinical trials are conducted specifically for this age group. TBS could be an option in this population, offering the advantages of few side effects and no pharmacological interactions. Therefore, our aim is to investigate the (...) efficacy of TBS in geriatric depression.Clinical trial registration[https://clinicaltrials.gov/ct2/], identifier [NCT04842929]. (shrink)

Martín de Azpilcueta and his fellow Spanish Scholastics writing and teaching at the University of Salamanca during Spain’s Golden Age are rightly pointed to by historians of economic thought as being major contributors toward, if not outright founders of modern economic theory. Among these is the theory of time-preference for which Azpilcueta has repeatedly been given the credit for discovering. However, this discovery is a curious one given how the same man, Azpilcueta, condemned usury in general during his whole life. (...) If Azpilcueta did in fact discover this theory and fully understand its implications, we would reasonably expect him to have questioned his support for the ban on charging an interest on a loan. This paper, therefore, challenges the claim that Azpilcueta understood and revived time-preference theory and shows how his understanding was much more nuanced, and, at times, inconsistent. (shrink)

In the context of business, interactions between individuals generate social systems that emerge anywhere within a corporation or in its relations with external agents. These systems influence the behaviors of individuals and, as a result, the collective actions we usually attribute to corporations. Social systems thus make a difference in processes of action that are often morally evaluated by internal and external agents to the firm. Despite this relevance, social systems have not yet been the object of specific attention in (...) the literature on moral agency in business. To fill this gap, I construct a theoretical framework based on Luhmann’s ideas on social systems and morality. In particular, I argue that morality is a phenomenon that occurs in communication, and an agent can engage in morality in three different ways (as a _moral factor_, an _expressive moral agent_, or a _reflective moral agent_) depending on the functions it plays in communicative interactions. Based on this framework, I argue that social systems in business can be considered moral agents of those types. (shrink)

The first in-depth analysis of the radical feminist theory and coalitional praxis of scholar-activist María Lugones. Speaking Face to Face provides an unprecedented, in-depth look at the feminist philosophy and practice of the renowned Argentinian-born scholar-activist María Lugones. Informed by her identification as “nondiasporic Latina” and US Woman of Color, as well as her long-term commitment to grassroots organizing in Chicana/o communities, Lugones’s work dovetails with, while remaining distinct from, that of other prominent transnational, decolonial, and women of color feminists. (...) Her visionary philosophy motivates transformative modes of engaging cultural others, inviting us to create political intimacies rooted in a shared yearning for interdependence. Bringing together scholars and activists across fields, this volume charts her profound impact in and beyond the academy for the past thirty years. In so doing, it exemplifies a new method of coalitional theorizing—traversing racial, ethnic, sexual, national, gendered, political, and disciplinary borders in order to cultivate learning, embrace heterogeneity, and provide a unique framework for engaging contemporary debates about identity, oppression, and activism. Across thirteen original contributions, authors address issues of intersectionality, colonial and decolonial subjectivities, the multiplicity and the coloniality of gender, indigenous spiritualities and cosmologies, pluralist and women of color feminisms, radical multiculturalism, popular education, and resistance to multiple oppressions. The book also includes a rare interview with Lugones and an afterword by Paula Moya, ultimately offering both new critical resources for longstanding admirers of Lugones and a welcome introduction for newcomers to her groundbreaking work. “This is an important contribution to Latinx studies, Latina feminist philosophy, queer studies, and the burgeoning field of decolonial feminism, a field that Lugones almost single-handedly launched. It is interdisciplinary, but also a wonderful pedagogical resource. It provides readers who are both familiar and unfamiliar with her work a thorough and judicious point of entry.” — Eduardo Mendieta, author of Global Fragments: Globalizations, Latinamericanisms, and Critical Theory.

Es un lugar común afirmar que recurrir al contexto es un paso inexcusable de cara a comprender una proferencia o un texto y que tal comprensión es inexcusable asimismo de cara a traducir (correctamente) una proferencia o un texto dados. No obstante, a pesar de que una proferencia o texto puedan ser bien comprendidos, su traducción depende de la posibilidad de (o habilidad para, en su caso) identificar sinonimias entre la lengua origen y la lengua término, especialmente cuando entran en (...) juego fenómenos lingüísticos tales como la ambigüedad, los falsos amigos, la hiponimia o la vaguedad. Cuando tales fenómenos entran en juego las implicaciones y las implicaturas que está permitido hacer de una proferencia o un texto traducidos pueden diferir de las que está permitido hacer del texto original. Teniendo en cuenta estas consideraciones previas, este artículo trata del análisis de las implicaciones e implicaturas que está permitido hacer cotejando textos filosóficos originales y sus traducciones a varias lenguas. Este análisis sugiere que muchos textos filosóficos traducidos crean nuevos contextos, de modo que se posibilitan nuevas interpretaciones del pensamiento de un filósofo dado. (shrink)

In this paper we present a semantic analysis of the application of didactic constructivism to chemical education. We show that the psychological basis of constructivism yield, when applied to chemistry, an internalist semantics for the chemical names. Since these names have been presented as typical examples of an externalism for kind terms, a fundamental incompatibility ensues. We study this situation, to conclude that it affects chemical education at every level. Finally, we present a preliminary analysis of this problem from the (...) point of view of physics. (shrink)

Prior research has found attributions to mediate the relationship between the elements of corporate social responsibility activities and consumer responses to firms; however, the question of what variables determine consumer attributions of CSR remains partially unaddressed. This article analyzes why consumers make attributions of CSR that are either positive, or negative. The results obtained from two empirical studies indicate that company–cause fit, corporate ability, and interpersonal trust have a positive influence on the motives that consumers attribute to CSR, whereas corporate (...) hypocrisy has a negative effect. This research contributes to our understanding of the psychological mechanisms underlying impactful consumer judgments and provides guidance for organizations in responding to such evaluations.

I put forward an inferentialist account of Lewis structures (LSs). In this view, the role of LSs is not to realistically depict molecules, but instead to allow surrogate reasoning and inference in chemistry. I also show that the usage of LSs is a central part of a person’s identity as a chemist, as it is defined within educational identity theory. Taking these conclusions together, I argue that the inferentialist approach to LSs and chemistry identity theory can be studied in parallel, (...) as two complementary sides of the same research programme.

We argue for an account of chemical reactivities as chancy propensities, in accordance with the ‘complex nexus of chance’ defended by one of us in the past. Reactivities are typically quantified as proportions, and an expression such as “A + B → C” does not entail that under the right conditions some given amounts of A and B react to give the mass of C that theoretically corresponds to the stoichiometry of the reaction. Instead, what is produced is a fraction (...) α < 1 of this theoretical amount, and the corresponding percentage is usually known as the yield, which expresses the relative preponderance of its reaction. This is then routinely tested in a laboratory against the observed actual yields for the different reactions. Thus, on our account, reactivities ambiguously refer to three quantities at once. They first refer to the underlying propensities effectively acting in the reaction mechanisms, which in ‘chemical chemistry’ (Schummer in Hyle 4:129–162, 1998) are commonly represented by means of Lewis structures. Besides, reactivities represent the probabilities that these propensities give rise to, for any amount of the reactants to combine as prescribed. This last notion is hence best understood as a single case chance and corresponds to a theoretical stoichiometric yield. Finally, reactivities represent the actual yields observed in experimental runs, which account for and provide the requisite evidence for/against both the mechanisms and single case chances ascribed.

RESUMEN A pesar de que la reducción de R. Descartes de los animales a meras máquinas puede explicarse como una consecuencia lógica de su punto de partida metafísico y gnoseológico, se puede argüir que esta reducción parece muy difícil de defender, puesto que se nos antoja contradictoria con nuestra experiencia cotidiana. Por otra parte, uno de los propósitos de la filosofía de Descartes es la “conservación de la salud”, que puede conseguirse mediante el establecimiento de una medicina “fundada en demostraciones (...) infalibles”. De cara a conseguir tal medicina el primer paso es alcanzar el conocimiento más preciso posible del cuerpo humano a fin de tener éxito en la práctica de la cirugía. De ahí que sea bastante plausible afirmar que la metafísica y la teoría del conocimiento de Descartes no serían sus principales intereses teóricos, sino solamente una explicación y justificación ingeniosas de lo que la ciencia de su tiempo llevaba haciendo no menos de cien años antes de él, así como una inteligente manera de obviar los escrúpulos cuando se anatomizaban cadáveres humanos y animales. En consecuencia, en este artículo mantendremos que el mecanicismo y dualismo cartesianos son una verdadera filosofía de la ciencia, desde el momento en que ambos estaban dedicados a explicar y justificar lo que la ciencia estaba haciendo en la práctica. ABSTRACT Despite of the fact that R. Descartes’s reduction of animals to mere machines can be explained as a logical consequence of his metaphysical and gnoseological starting point, one can argue that this reduction seems to be very difficult to defend, since it appears to be contradictory to our everyday experience. On the other hand, one of the explicitly confessed purposes of Descartes’s philosophy is the “conservation of health”, which can be achieved by establishing a medicine “founded in infallible demonstrations”. The first step in order to get such medicine is to acquire the most accurate as possible knowledge of the human body in order to be successful in practicing surgery. That is why it is fairly plausible to state that Descartes’s metaphysics and theory of knowledge were not his main theoretical concerns, but only a witty explanation and justification of what the science of his time was doing for no less than one century before him, as well as a clever manner to avoid scruples when anatomising both human corpses and animals. Consequently, in this paper we will claim that Cartesian mechanicism and dualism are actual philosophies of science, given the fact that both were devoted to explain and justify what science was in practice doing.

Industrial development in recent decades has led to using information and communication technologies to support personnel selection processes. One of the most notable examples is game-related assessments, supposedly as accurate as conventional tests but which generate better applicant reactions and reduce the likelihood of adverse impact and faking. However, such claims still lack scientific support. Given practitioners’ increasing use of GRA, this article reviews the scientific literature on gamification applied to personnel selection to determine whether the current state of the (...) art supports their use in professional practice and identify specific aspects on which future research should focus. Following the PRISMA model, a search was carried out in the Web of Science and Scopus databases, identifying 34 valid articles, of which 85.3% are empirical studies that analyze five areas: validity; applicant reactions; design of GRA; personal characteristics and GRA; and adverse impact and faking. Together, these studies show that GRA can be used in personnel selection but that the supposed advantages of GRA over conventional tests are fewer than imagined. The results also suggest several aspects on which research should focus, which could help define the situations in which the use of GRA may be recommended. (shrink)

A pesar de que la alusión es ampliamente usada por poetas, escritores y filósofos así como en el lenguaje cotidiano, sus características y alcance como instrumento cognitivo se han estudiado escasamente. Esto es cierto hasta el extremo de que el sustantivo alusión no es merecedor de una humilde entrada en diccionarios y enciclopedias especializados, no solamente de filosofía, sino tampoco de lingüística. Teniendo en cuenta este status quaestionis, este trabajo intenta conseguir los siguientes objetivos, a saber: 1) mostrar que la (...) alusión es un instrumento cognitivo; 2) delimitar la alusión con respecto a la cita, el plagio y el eco; 3) considerar la alusión como un caso de implicatura; y 4) analizar las principales características de la alusión.

Open peer commentary on the article “Constructivist Model Building: Empirical Examples From Mathematics Education” by Catherine Ulrich, Erik S. Tillema, Amy J. Hackenberg & Anderson Norton. Upshot: I argue that radical constructivism poses a series of deep methodological constraints on educational research.

The introduction of a new analytical method, due fundamentally to François Viète and René Descartes and the later dissemination of their works, resulted in a profound change in the way of thinking and doing mathematics. This change, known as process of algebrization, occurred during the seventeenth and early eighteenth centuries and led to a great transformation in mathematics. Among many other consequences, this process gave rise to the treatment of the results in the classic treatises with the new analytical method, (...) which allowed new visions of such treatises and the obtaining of new results. Among those treatises is the Arithmetic of Diophantus of Alexandria which was written, using the new algebraic language, by the French mathematician Jacques Ozanam, who in addition to profusely increasing the original problems of Diophantus, solved them in a general way, thus obtaining many geometric consequences. The work is handwritten, it has never been published, it has been lost for almost 300 years, and the known references show its importance. We will show that Ozanam’s manuscript was quoted as an important work on several occasions by others mathematicians of the time, among whom G. W. Leibniz stands out. Once the manuscript has been located, our aim in this article is to show and analyze this work of Ozanam, its content, its notation and its structure and how, through the new algebraic method, he not only solved and expanded the questions proposed by Diophantus, but also introduced a connection between the algebraic solutions and what he called geometric determinations by obtaining loci from the solutions.

This study tested the direct effects of Dark Tetrad traits on organizational and interpersonal counterproductive work behaviors. We also examined the moderating effects of the three dimensions of organizational justice – distributive justice, procedural justice, and interactional justice – on the Dark Tetrad-CWBs relationships. Based on the data from 613 employees across different occupations, the results revealed that only psychopathy and sadism had significant effects on CWBs targeted at the organization. The results also supported the direct effect of sadism on (...) interpersonal CWBs. The findings confirmed the moderating role of interactional justice but differentially, depending on the dark trait and the target of workplace deviance. Whereas low and medium levels of interactional justice moderated the relationship between Machiavellianism and CWBs directed to the organization, it did not play any role in narcissism, psychopathy, and sadism. Regarding CWBs aimed at other people, interactional justice emerged as a significant moderator in Machiavellianism and sadism. But, whereas sadistic employees performed more harmful behaviors toward other individuals whatever their level of interactional justice, if people high in Machiavellianism perceived a high fair interpersonal treatment, they did not show deviant behaviors directed at other employees. The paper concludes with some suggestions and recommendations about the relevance of organizational justice in the influence of dark personality traits on CWBs. (shrink)

Knowledge of diverse sexual motivations can have profound implications for our comprehension of the causes, correlations, and consequences of sexual behavior. This study had two objectives: on the one hand, to determine the different motives why young Spanish university students have sex and their relationship with different sociodemographic and psychosexual variables and sexual behavior; on the other hand, to review and improve the psychometric properties of the Sexual Motivations Scale and validate it in Spanish. Participants were 805 university students of (...) both sexes, aged between 18 and 26 years, who completed a battery of online questionnaires. Significant associations were found between young people's sexual motives, especially the motives of coping, peer pressure, and enhancement, the sociodemographic variables, sexual behavior, and psychosexual variables. Also, a new structure of the Sexual Motivations Scale was proposed, with the elimination of the factor of Self-Affirmation. The discussion highlights the relevance of the results obtained due to their implications in the promotion of sexual health, in addition to achieving the first instrument validated in Spanish for the evaluation of sexual motivations.

We offer tableaux systems for logics of essence and accident and logics of non-contingency, showing their soundness and completeness for Kripke semantics.

In keeping with the radical openness of his theory of democracy, Habermas avoided pre-determining the ideal mode of economic organization for his favoured model of deliberative democracy. Instead of attempting a full-blown derivation, in this article, I propose adapting the Rawlsian method of comparing different political–economic regimes as candidate applications of his theory of justice to Habermas’s theory of deliberative democracy. Although both theorists are seen as endorsing liberal democratic world views, from the perspective of political economy, the corollary of (...) their conceptions of democracy would arguably veer elsewhere: in Rawls’s case, into the territory of property-owning democracy or democratic socialism, and in Habermas’s, into any political–economic regime which guarantees the real exercise of full political and discursive liberties against the background of legitimate lawmaking. The ultimate aim of this article is to discuss whether a concrete conception of democratic socialism, if any, is compatible with Habermas’s theory of deliberative democracy. (shrink)

The main goals of this study were, to test the motivational determinants of athletes perceived effort in football considering the four-stage motivational sequence at the contextual level proposed by Hierarchical Model of Intrinsic and Extrinsic Motivation: task-involving, basic psychological needs, self-determined motivation and perceived effort. The multi-group analysis across different age-groups (U15, U17, U19, U21 years) and mediation role of basic psychological needs and self-determined motivation on the task-involving climate and the perceived effort were also analysed. Two independent samples of (...) male football athletes (N= 403, N= 403), aged 13-20 were enrolled in this study. The results demonstrated that structural model provided a good fit to data for all samples under analysis, and was invariant across U17, U19, and U21. However, it was not invariant across U15 and U17, U19 and U21. Additionally, in the results from the mediation analysis, there were significant indirect effects in all samples, supporting theoretical by self-determination theory assumptions, reinforcing the importance of basic psychological needs satisfaction and behavioral regulation in the relation in analysis. The results allow concluding that when coaches promote a task-involving climate, the basic psychological needs satisfaction of athletes improves. This climate will facilitate the regulation of their behaviors towards more autonomous forms of motivation, with positive results in the perceived effort of the athletes. (shrink)

Previous studies making use of indirect processing measures have shown that perceptual grouping can occur outside the focus of attention. However, no previous study has examined the possibility of subliminal processing of perceptual grouping. The present work steps forward in the study of perceptual organization, reporting direct evidence of subliminal processing of Gestalt patterns. In two masked priming experiments, Gestalt patterns grouped by proximity or similarity that induced either a horizontal or vertical global orientation of the stimuli were presented as (...) masked primes and followed by visible targets that could be congruent or incongruent with the orientation of the primes. The results showed a reliable priming effect in the complete absence of prime awareness for both proximity and similarity grouping principles. These findings suggest that a phenomenal report of the Gestalt pattern is not mandatory to observe an effect on the response based on the global properties of Gestalt stimuli. (shrink)

Ian Rumfitt (2000) developed a bilateralist account of logic in which the meaning of the connectives is given by conditions on asserted and rejected sentences. An additional set of inference rules, the coordination principles, determines the interaction of assertion and rejection. Fernando Ferreira (2008) found this account defective, as Rumfitt must state the coordination principles for arbitrary complex sentences. Rumfitt (2008) has a reply, but we argue that the problem runs deeper than he acknowledges and is in fact related to (...) the challenge of establishing proof-theoretic harmony. We motivate a distinctively bilateral criterion for harmony and show how the bilateralist can meet it. This also resolves Ferreira's complaint. (shrink)
