We discuss the axiomatization of generalized consequence relations determined by non-deterministic matrices. We show that, under reasonable expressiveness requirements, simple axiomatizations can always be obtained, using inference rules which can have more than one conclusion. Further, when the non-deterministic matrices are finite we obtain finite axiomatizations with a suitable generalized subformula property.

O presente trabalho retrata os resultados de uma pesquisa realizada nos moldes da observação participante e da etnobiografia com o objetivo de compreender a dinâmica existente entre o ensino e aprendizagem e os valores civilizatórios inerentes às práticas cotidianas de uma comunidade tradicional afro-brasileira. O estudo foi realizado por meio da observação e participação de atividades litúrgicas de um terreiro de Umbanda e Candomblé – o “Ilè Asè Tobi Babá Olòrigbìn” - localizado na cidade de Ituiutaba, MG. O ensinar como (...) uma responsabilidade partilhada, a reafirmação de princípios éticos/civilizatórios (como a circularidade, a ancestralidade, a corporalidade, a conduta), a centralidade da oralidade e as relações entre a vida comunitária e uma singularidade que se funda no coletivo foram aspectos percebidos como características de uma dimensão formativa que orienta os aprendizados no interior desse grupo. Considerando que o modelo praticado por essas comunidades seja um modelo de sucesso (que tem resistido ao tempo e a um histórico de opressão), destacamos o grande desafio de aprender com os ensinamentos dos territórios afro-brasileiros e encontrar maneiras de incorporá-los às nossas práticas educativas, para que assim, vislumbremos uma escola mais diversa e humanizada.

: In recent years, research on the family role and entrepreneurship has increased extremely, consolidating itself as a valid and current subject of study. However, a part of the scientific literature seems to lack systematization and the boundaries appear unclear, maybe due to its multidisciplinary nature. This paper presents a systematic analysis of academic research, applying bibliometric indicators and cluster analysis, which define the state of research on the international scene. For this purpose, using three well accepted databases among the (...) research community: Scopus, Web of Science, Business Source, a total of 92 articles were selected and analyzed, published between 1989 and 2019 (until March). The results show that this is a relatively recent field of study, with a multidisciplinary character and in which the most influential authors do not coincide with the most productive scientific journals. A cluster analysis finds out five main areas of literature development: the cluster with the largest percentage of co-occurrences (25%) is the one that relates to the dimensions of entrepreneurship, self-employment and personality; in contrast, the area with a lower percentage of co-occurrences of keywords (12,1%) is refers to family business, succession, economic development and Arabia Saudita. Based on the outcome obtained and the shortcomings above, in the final part of the article, possible points of reflection for future research are exposed, which could be useful to further of this field of study.

In the current digital era, the borders amongst firms are getting blurred when it comes to value creation. Therefore, the traditional configuration of the value chain is frequently replaced by other ones which include the collaborative participation of different agents. Within this context, global value chains, where the value activities are located in different countries, and industrial clusters, which combine competition and cooperation, are attracting a growing attention of both business leaders and scholars in the recent years. Through a bibliometric (...) analysis, this paper disentangles the intellectual and conceptual structure of the research topic of industrial clusters and global value chains. Results show the multidisciplinary character of the topic, including papers published in different areas, such as business, regional studies and world development, as well as its close link with aspects like innovation, regional development, governance or organization. Finally, this study remarks the research lines that could attract more attention in the immediate future. (shrink)

Aberrations introduced by the atmospheric turbulence in large telescopes are compensated using adaptive optics systems, where the use of deformable mirrors and multiple sensors relies on complex control systems. Recently, the development of larger scales of telescopes as the E-ELT or TMT has created a computational challenge due to the increasing complexity of the new adaptive optics systems. The Complex Atmospheric Reconstructor based on Machine Learning is an algorithm based on artificial neural networks, designed to compensate the atmospheric turbulence. During (...) recent years, the use of GPUs has been proved to be a great solution to speed up the learning process of neural networks, and different frameworks have been created to ease their development. The implementation of CARMEN in different Multi-GPU frameworks is presented in this paper, along with its development in a language originally developed for GPU, like CUDA. This implementation offers the best response for all the presented cases, although its advantage of using more than one GPU occurs only in large networks. (shrink)

“Postularse como un ser radicalmente autogenerado, ser el autor de la propia voluntad y conocimiento, es negar que uno está constituido en y por lo que es infinitamente más grande que el individuo humano. Kierkegaard llamará a esta fuente más grande que todo lo humano 'Dios' o 'el infinito'. Negar que uno está constituido en lo que es más grande que uno mismo es, para Kierkegaard, estar en una especie de desesperación”.

There is an increasing demand by society that university students demonstrate competitive skills to enable them to achieve greater success when entering the workplace. Creativity and life satisfaction correlate positively with academic performance, productivity, and excellence in the working environment. The presence of creativity and emotional intelligence in the curriculum and teaching methods in Spanish universities, however, is surprisingly lacking. Studies that examine gender differences in these variables provide conflicting results. The purpose of our research is to analyse the changes (...) produced in both creativity and life satisfaction in university students by a positive emotional and creative intervention and explore individual differences by gender. The methodology used was a quasi-experimental pre- test/post- test design with experimental/control groups. Three hundred university students from the Community of Madrid completed three exercises that evaluated creativity and life satisfaction. The results show significantly higher results in creativity and life satisfaction in women, who continued to achieve high results after the intervention. Finally, we discuss the need for emotional and creative education in universities and focus on the employability and the guarantee of equal opportunities through the development of these competencies.

Hearing loss has been identified as a major modifiable risk factors for dementia. Adult candidates for cochlear implantation represent a population at risk of hearing loss-associated cognitive decline. This study investigated the effect of demographics, habits, and medical and psychological risk factors on cognition within such a cohort. Data from 34 consecutive adults with post-lingual deafness scheduled for CI were analyzed. Pure tone audiometry and Speech Discrimination Score were recorded. The Repeatable Battery for Assessment of Neuropsychological Status for Hearing impaired (...) individuals was used to measure cognition. Demographics, habits, and medical factors were evaluated. Depression was measured using the Hospital Anxiety and Depression Scale, and social inhibition with the Type D questionnaire. All participants suffered from severe to profound hearing loss. The mean RBANS-H total score was 83 ± 16. Participants reported a mean of years of formal education of 12 ± 5 years. The prevalence of habits and medical risk factors was: physical inactivity, body mass index >30, traumatic brain injury, hypertension, heavy alcohol consumption, smoking, and diabetes. Regarding psychological factors, the mean scores of social inhibition and depression were 10 ± 6 and 6 ± 5, respectively. The number of years of education was significantly correlated with the RBANS-H total score, and with the domains “Immediate memory”, “Visuospatial/constructional”, and “Attention”. The mean RBANS-H total score in participants who had university studies or higher level was 97 ± 9, with the remaining participants reporting a mean score of 75 ± 15. Men performed better in the “Visuospatial/constructional”. Physical inactivity was associated with lower scores in the “Delayed memory” ; hypertension correlated with lower RBANS-H total scores and “Attention”. Depression and social inhibition were negatively correlated with RBANS-H total score and with the “Immediate memory,” “Visuospatial/constructional,” and “Attention”. In adults with late-onset deafness scheduled to CI, educational level has a significant effect. Additionally, sex, physical inactivity, hypertension, and psychological traits of social inhibition and depression may also influence cognitive status. Long-term studies with more participants would enable us better understand the effects different risk factors on cognitive status. (shrink)

Most ethical considerations related to the activities of the professions, including that of social education, have been put forward using a set of professional ethics that are frequently associated with principles and imperatives that aspire to be universal but have little connection to real and specific situations. In this paper, we offer an interpretation of the ethics associated with the profession of social educator from positions that are less transcendent, more immanent. Such an interpretation is based on and built from (...) professional practice, from actual, relational situations that social educators have experienced in the real contexts in which they work. Following a discussion on the usefulness of reflecting about the ethical dimensions of educational activity, we look at situations in which social educators, immersed in relationships, put their skills and competencies to use, and we propose some guidelines for an ethical practice of the educational relationships in this field.

The development of information and communication technologies offers innovative opportunities to establish business strategies focused on customer value co-creation. This situation is especially notable in the banking industry. e-Banking activities can support competitive advantages. However, the adoption of e-banking is not yet well-established among consumers. In this sense, the technology acceptance model is considered essential in studying consumer behavior applied to adopt a particular technology. According to the TAM model, this study analyses the factors which influence bank customers to adopt (...) e-banking to facilitate their banking services and support the process of value co-creation. Consequently, the authors examine five main aspects of the technology adoption model to provide a broad understanding of bank customers’ consumption of e-banking. A partial least squares structural equation modeling analysis is conducted to evaluate proposed relationships between factors and customers’ e-banking adoption. (shrink)

Este texto se centra en la génesis de las ciencias sociales a través de una reflexión analítico- descriptiva sobre la sistematización de la ciencia. La ciencia es una creación del ser humano y constituye la mejor herramienta para adquirir conocimientos acerca de su entorno, de sí mismo, del universo... Debe ser interdisciplinaria y para dar soporte a este empeño, hemos tenido que elegir, y hemos optado por comparar la sociología con la filosofía buscando aportaciones (implícitas o explícitas) de prestigiosos pensadores.

Religion and spirituality (R/S) serve as coping mechanisms for circumstances that threaten people’s psychological well-being. However, using R/S inappropriately to deal with difficulties and problems in daily life may include the practice of Spiritual Bypass (SB). SB refers to avoiding addressing emotional problems and trauma, rather than healing and learning from them. On the other hand, coping strategies may be determined by the cultural context. This study aims to describe the presence of SB in individuals who may have experienced stressful (...) situations and to understand the influence of culture on SB by comparing SB in two culturally different groups. The sample consists of a total of 435 people, 262 of Honduran nationality and 173 of Spanish nationality. Both groups are approximately equivalent in age and gender. The degree of SB, stressful events, perception of social support and spiritual well-being are examined, respectively, through the Spiritual Bypass Scale, and specific items and subscales from the Social Readjustment Rating Scale, Multidimensional Scale of Perceived Social Support, and the Functional Assessment of Chronic Illness Therapy - Spiritual Wellbeing. The results showed a higher spiritual well-being and use of SB in the Honduran sample as compared to the Spanish sample, but similar social support and stressful events. Furthermore, some of the factors predicting SB were different between the two samples. While age and a greater number of R/S practices were important in both samples, for the Honduran sample the variables that best explained SB were being a Christian, having greater social support, fewer stressful events, and greater attendance at church or temple. For the Spanish sample, however, the variable that best explained SB was studying R/S texts. Therefore, SB must be understood within the culture in which it develops, since in different cultural contexts it appears to relate to differing factors. Thus, SB becomes a possible functional or dysfunctional coping strategy depending on the social context. (shrink)

La vigilancia tecnológica, que comienza como un mecanismo empresarial de captación y fidelización clientelar, ha conocido un desarrollo tecnológico tal que, junto a la obtención masiva de datos producidos de forma inconsciente y su tratamiento por la inteligencia artificial, ha permitido la anticipación de las tendencias y la supervisión constante de los deseos e intereses de los usuarios. La integración de vigilancia y consumo ha supuesto que esta lógica del mercado pueda ser entregada a la gubernamentalidad, transformando la racionalidad disciplinaria (...) estática en múltiples dinámicas de observación de una población móvil pero controlable en términos biopolíticos, de modo que el deseo y la libertad se convierten así en dimensiones activas de una economía política actual. Se ofrecen algunos ejemplos de este auténtico panoptismo digital, como puede comprobarse con el uso de navegadores, las aplicaciones financieras, la hipersegmentación de nichos de consumo o el internet de las cosas. Por último, se analiza el tránsito de esta vigilancia hacia una lógica de gobierno basada en la predeterminación de los intereses: es el paso del panoptismo a la gubernamentalidad. (shrink)

This paper uses a sample of 1243 international firms for the period 2013–2017 to analyse the effect that a greater presence of women in management teams has on business behaviour in relation to labour and human rights, and the mediating role of improved performance in these rights on corporate transparency. The results show that gender diversity in management teams is positively associated with performance in relation to labour and human rights, and that such a performance acts as a mediating factor (...) by fostering a higher disclosure of information regarding these issues. The findings therefore seem to indicate that the presence of women in management teams acts as a driving force for enhanced social responsibility. (shrink)

Resumen Los quichuas ecuatorianos en Cali conforman un grupo transnacional sociopolíticamente organizado. En situación de contacto asimétrico con respecto a la población mayoritaria, han desarrollado diversas estrategias de adaptación al medio urbano. Una de ellas, sociolingüística y pragmática, es la apropiación y uso del debilitamiento del fonema /s/, una de las características fonéticas e identitarias más relevantes del español de Cali. Este rasgo fonético no se observa en el español andino ecuatoriano que hablan originalmente los quichuas. Sin embargo, la situación (...) de contacto asimétrico en la que ellos están inmersos en Cali hace que la apropiación y uso del debilitamiento del fonema /s/ adquiera un valor socio-pragmático que les permite negociar posicionamientos sociales o stances en la interacción.

The Neoplatonic commentaries on Aristotle’s works have always been considered somehow suspicious. That is partly related to the doctrinal commitments of the commentators, partly with the hermeneutical strategies to which they seem to recur. Both of these reasons have also give place to the accusation of distortion and misunderstanding of Aristotle’s philosophy. In the following paper I want to perform an exercise of disclosing the hermeneutical procedure that one of this commentators applies to one of the passages of the first (...) book of the De Anima. The commentator is Philoponus, the passage is the refutation of the soul-harmony theory. My aim is to show that, despite the doctrinal commitments that the commentator may have, his methodology follows Aristotelian guidelines. I hope that this could open perspectives on the value that the commentators must have as philosophers, rather than merely interpreters or paraphrasers. (shrink)

This study analyses the emotional exhaustion of students inhigher education, derived from the extremely technology-relatedstrain associated to the current COVID-19 pandemic in a conservation of resources’ approach. Technostress, as source of emotional exhaustion, was investigated in a sample of 333 students in a medium size public university in Spain. Data was collected in May 2020, during the COVID lockdown. After literature review, a structural model was developed, linking technostress with emotional exhaustion. Results confirm the expected cause-effect relationships. In addition, the (...) study reveals two mediator variables that must be considered when managing students′ suffering, perceived stress and intrapersonal conflicts. This study contributes to the academic literature in the field of managing and mitigating suffering. They do so by providing both new knowledge and empirical evidence on the effects of technostress in the new generations that will soon join the working life. (shrink)

The university that Alasdair MacIntyre defines as liberal is that which rejects the tradition as something pre-modern and with an impediment for the progress, including the pedagogic one. This university model has been extended in all instances, giving priority to the technical education in a pragmatic way. Thus, the global and sapiential vision of the university has been relegated. This last approach is the key for unifying the knowledge and to pass it onto other people and, therefore, to educate and (...) mold intellectually and morally. However, the professionalization of the philosophy and the criteria of the modern liberalism seem to dominate and inspire most universities in the present day. This situation has plainly shown an inability to become aware of their incompetence to properly educate professors and students alike, in a sapiential and moral manner, threfore deceiving themselves with a naive rhetoric.

Extant literature suggests a correlation between the thematic core of an adolescent’s personal account of depression and the trajectory of her personality development. This possible correlation has not been explored in a way that includes detailed qualitative analyses of reported experiences of adolescent depression. By discussing a single case design, this contribution illustrates and justifies an interpretative procedure that has been implemented to assist such an exploration. The paper focuses on the suitability of this approach for the investigation of all-encompassing (...) alterations of the experiential field in psychopathological conditions. I argue that this suitability is grounded in a phenomenological understanding of the explicative task in terms of a disclosure of the intentional constitution of the life-world of adolescent depression. The discussion begins with a contextualization of the single case design within a multilayered and methodologically mixed study. Against this background, I illustrate the steps of a ‘systematic of interpretation’ aimed at exposing meaning horizons. Touching on issues concerning the empirical validity of the approach, these meaning horizons are construed as objectively plausible frames of intelligibility of a subjectively particular form of experience. Drawing on a characterization of transcendental arguments, I discuss the relationship between the illustrated procedure and the investigational attitude that, according to Husserl, defines phenomenology as a properly philosophical endeavor. In this context, I eventually characterize the illustrated procedure as a crossover approach to human experiential life aligned with the tradition of phenomenological psychopathology. (shrink)

The impact of digital devices and the Internet has generated various changes at social, political, and economic levels, the repercussion of which is a great challenge characterized by the changing and globalized nature of today's society. This demands the development of new skills and new learning models in relation to information and communication technologies. Universities must respond to these social demands in the training of their future professionals. This paper aims to analyze the empirical evidence provided by international studies in (...) the last eleven years, related to the digital literacy of university students, including those pursuing degrees related to the field of education. Our findings highlight the fact that the digital literacy that is offered in universities to graduate/postgraduate students, in addition to treating digital literacy as a central theme, also focuses on perceived and developed self-efficacy. This is done by strengthening competencies related to digital writing and reading, the use of databases, the digital design of content and materials, and the skills to edit, publish or share them on the web, or applications aimed at treating digital literacy as emerging pedagogies and educational innovation. Secondly, we found studies related to digital competencies and use of the Internet, social networks, web 2.0, or the treatment of digital risks and their relationship with digital literacy. Thirdly, we found works that, in addition to focusing on digital literacy, also focused on different psychological constructs such as motivation, commitment, attitudes, or satisfaction.Systematic review registration:https://www.scopus.com/home.uri; https://www.recursoscientificos.fecyt.es/.

En este trabajo estudiaremos la presencia de imágenes hagiográficas que se pueden considerar ajenas al ciclo de la Pasión de Cristo en las procesiones penitenciales españolas a lo largo de la historia, deteniéndonos fundamentalmente en aquellas que por méritos propios han sido merecedores de presidir un paso procesional en solitario.
