This paper has a double purpose: firstly, to assess the importance of seiðr magic rituals and of its practitioners within the social and mythological framework of Old norse-icelandic Literature. Secondly, by means of the analysis of certain scenes in The Saga of Gísli Súrsson, i aim to demonstrate that the inclusion of magic-religious motifs in the Sagas of icelanders has a triple objective: to provide a model to help understand apparently inexplicable phenomena, to intensify the tragic tone of the plot (...) and finally to depict those involved in the performance of seiðr in a very negative light.

El artículo examina el papel de Crescas y Spinoza en la transición de la concepción medieval a la concepción moderna del universo. Crescas es presentado como ejemplo ilustrativo de la tensión entre aristotelismo y religión revelada y de cómo esta última provoca la disolución del aquel, allanando así el camino a la concepción moderna del universo. A continuación, se muestra cómo la concepción moderna se plasma en el pensamiento de Spinoza, el cual radicaliza algunos de sus rasgos definitorios. Esta radicalización (...) socava la noción tradicional del _Deus absconditus_ y conduce en Spinoza al remplazo de la religión por la filosofía como auténtica revelación divina. (shrink)

Una consecuencia de la revolución digital es la aparición del big data, que puede ser considerado como un elemento fundamental para la constitución de eso que autores como Byung-Chul Han denominan “psicopolítica”. Según Han, la sociedad en que vivimos tiene dos fundamentales características que se complementan entre sí: la nuestra es una “sociedad de la transparencia” y también una “sociedad digital”. Estas dos características tienen negativas consecuencias para los humanos. Siguiendo a Foucault y Deleuze, Han considera que el ser humano (...) será capaz de escapar de la esclavitud impuesta por él mismo si logra transformar el peso cualitativo de sus acciones. Es decir, si consigue que estas, en lugar de ser perfectamente predecibles y calculables, pasen a ser acontecimientos, en el pleno sentido de esta palabra: creaciones impredecibles que contribuyan, en términos nietzscheanos, a su autosuperación y, por ende, a hacer de su vida una obra de arte.

El articulo examina la aparente discrepancia en el pensamiento de Spinoza entre su teocentrismo epistemológico, según el cual todo es dudoso mientras desconocemos la existencia de Dios, y el principio verum index sui et falsi, según el cual la mera posesión de ideas verdaderas excluye toda incertidumbre. Lejos de contradecirse, estas dos afirmaciones constituyen en Spinoza dos aspectos correlativos del mismo planteamiento gnoseólogico. Se muestra así que la naturaleza divina no es ajena al intelecto humano y que este es capaz (...) de contemplar la realidad desde una perspectiva omnímoda, idéntica a la de Dios. (shrink)

Background: Frailty is a common syndrome among older adults and patients with several comorbidities. Grip strength is a representative parameter of frailty because it is a valid indicator of current and long-term physical conditions in the general population and patients with severe mental illnesses. Physical and cognitive capacities of people with SMIs are usually impaired; however, their relationship with frailty or social functioning have not been studied to date. The current study aimed to determine if GS is a valid predictor (...) of changes in cognitive performance and social functioning in patients with type-2 diabetes mellitus and SMIs. Methods: Assessments of social functioning, cognitive performance, and GS were conducted in 30 outpatients with type 2 diabetes mellitus, 35 with major depressive disorder, 42 with bipolar disorder, 30 with schizophrenia, and 28 healthy controls, twice during 1-year, follow-up period. Descriptive analyses were conducted using a one-way analysis of variance for continuous variables and the chi-squared test for categorical variables. Differences between groups for the motor, cognitive, and social variables at T1 and T2 were assessed using a one-way analysis of covariance, with sex and age as co-variates. To test the predictive capacity of GS at baseline to explain the variance in cognitive performance and social functioning at T2, a linear regression analysis was performed. Results: Predictive relationships were found among GS when implicated with clinical, cognitive, and social variables. These relationships explained changes in cognitive performance after one year of follow-up; the variability percentage was 67.7%, in patients with type-2 diabetes mellitus and 89.1% in patients with schizophrenia. Baseline GS along with other variables, also predicted changes in social functioning in major depressive disorder, bipolar disorder, and schizophrenia, with variability percentages of 67.3, 36, and 59%, respectively. Conclusion: GS combined with other variables significantly predicted changes in cognitive performance and social functioning in people with SMIs or type-2 diabetes mellitus. Interventions aimed to improve the overall physical conditions of patients who have poor GS could be a therapeutic option that confers positive effects on cognitive performance and social functioning.

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)

El artículo examina la conexión esencial que existe entre la concepción hegeliana del signo y el funcionamiento del discurso especulativo en la Ciencia de la lógica. Partiendo de la tensión irresuelta en la filosofía kantiana entre la capacidad significativa del discurso y su autorreferencialidad, se somete a consideración el intento hegeliano de resolver dicha tensión en su tratamiento del lenguaje, contenido en la Enciclopedia de las ciencias filosóficas. De esta manera se pone al descubierto el modo sutil en que la (...) concepción hegeliana del signo permite superar las restricciones que Kant impone al discurso filosófico sin contravenir la prescripción básica de la filosofía crítica, según la cual todo pensamiento debe asociarse con una intuición para poder constituir un conocimiento con pretensión de validez. A partir de este resultado y centrándose en la estructura misma del signo tal y como la conceptualiza Hegel, se intenta esclarecer el funcionamiento exacto del discurso lógico y de los momentos básicos que lo constituyen –entendimiento, dialéctica y especulación–, mediante el ejemplo concreto de las tres primeras determinaciones de la Lógica: Ser. Nada y Devenir. (shrink)

Hegel's main criticisms of Spinoza are well‐known both among Spinoza and Hegel scholars. The role of Spinozism in Hegel's conception of philosophy turns out to be significantly more crucial than the rest of philosophies. This chapter argues that Spinoza's acosmism constitutes for Hegel the necessary condition for the rise and development of philosophy, and hence for the realization of human freedom, insofar as philosophy is the highest form of human freedom. It outlines the general conception of philosophy behind Hegel's statement (...) that Spinozism constitutes “the essential beginning of all philosophizing.” In Hegel's view, the greatness of Spinozism lies precisely in the radical de‐substantialization of finite things that it carries out, that is, in its acosmism.” Spinoza's acosmism clears the ground for the free exercise and unfolding of philosophical thinking.

Social entrepreneurship (SE) enables business consolidation, combined with the production of positive impact and improvements in society. Aligned with 2030 Agenda for the achievement of the United Nations Sustainable Development Goals, it is important to clarify the role of social entrepreneurs, as they are making visible the impact of their creative ideas in several areas, from civic engagement to the environment, health and learning. The main purpose of this study is to specify a model of social entrepreneurial intention (SEI) and (...) explore it by country, based on the dimensions of the Theory of Planned Behavior and how these are mediated by spirituality and optimism. With a convenience sample of 1476 Portuguese and Spanish students, Structural Equation Modeling (SEM) was used. For a deeply understanding, variables within the model were compared by country usingt-rest, and multivariate analysis was done by each one separately. The mean comparison between countries, demonstrated that there are differences only between perceived behavioral control (PBC), Spirituality, Optimism and SEI, with Portuguese students scoring the highest values, in all variables except Optimism. A mediation path was carried out, and Spirituality mediate a significant effect between the three TPB dimensions in Portuguese students, but not in students from Spain. Finally, after discussing the results, theoretical and practical contributions are analyzed, with regard to the field of SE in Portugal and Spain, and alternatives are pointed out for a more social and sustainable entrepreneurial future.

Nowadays, most loan transactions are contracted by using the exponential discounting as the underlying standard economic model to value this type of financial operations. In a framework of absence of fees to be paid by the borrower, the interest rate of the exponential discount function is, moreover, the true interest rate of the operation. Nevertheless, there exist a set of circumstances which make this identity false. Among others, these characteristics are: the use of linear discount as the underlying discount function, (...) splitting time when using a nominal interest rate, and the existence of fees in a loan at 0% interest rate. All these cases will be analyzed in this paper in the context of the so-called quick loans. (shrink)

In this article I analyze the connection between the concepts of “actuality”, “upcoming” and “origin” found in the early reflections of Walter Benjamin and Theodor W. Adorno to expose some of the defining borders of the transposition of criticisms made by both philosophers. Through the identification of “actuality” as a reflection on the conditions in which philosophy is legitimate, “upcoming” as a requisite for self-justification of philosophical knowledge, and “origin” as the claim of the historically unfinished, I show in what (...) sense a critical horizon is recovered by Benjamin and Adorno as an inexorable exercise of philosophical praxis.

Este trabajo reanuda y continúa la pregunta por la actualidad de la filosofía benjaminiana. Para ello, se prioriza la exploración de ciertos lineamientos epistemológicos y políticos determinantes de su concepción de la crítica (y no, en cambio, los enclaves estéticos, antropológicos y/o culturales). Se afirma como punto de partida que en el pensamiento de Walter Benjamin puede identificarse el sufrimiento como el origen de una epistemología crítica. A partir de ello, se aduce que la concepción benjaminiana de la crítica depende (...) de su concepción de la historia. Luego, se procura indicar que la crítica es expresión de la experiencia del sufrimiento y, al mismo tiempo, vivificación de la débil voz mesiánica de los muertos. Por último, se indaga la actualización aquí y ahora de la crítica benjaminiana: se argumenta que la filosofía que pone en el centro la colonialidad en cuanto configuración marginal del sufrimiento permite actualizar la teoría crítica en la medida en que evita la formalización de tal concepto.

El escrito continúa una discusión mantenida por Macarena Marey, María Julia Bertomeu y Nuria Sánchez Madrid en torno a la capacidad de los principios del republicanismo kantiano para transformar el espacio social en un ámbito en el que la autosuficiencia material constituya una de las condiciones fundamentales para que la igualdad formal ante la ley y la libertad política puedan actualizarse. En estas coordenadas se manifiestan también algunas discrepancias en lo concerniente a la percepción kantiana de las injusticias (...) sociales y políticas propias de su tiempo, si bien se alcanza el acuerdo de que el diseño institucional del republicanismo kantiano constituye un dispositivo conceptual suficiente para eliminar la desigualdad económica que comporta pasividad civil y política.

Unfortunately, there are still cases of domestic violence or situations where it is necessary to call for help without arousing the suspicion of the aggressor. In these situations, the help signal devised by the Canadian Women’s Foundation has proven to be effective in reporting a risky situation. By displaying a sequence of hand signals, it is possible to report that help is needed. This work presents a vision-based system that detects this sequence and implements it in a social robot, so (...) that it can automatically identify unwanted situations and alert the authorities. The gesture recognition pipeline presented in this work is integrated into a cognitive architecture used to generate behaviours in robots. In this way, the robot interacts with humans and is able to detect if a person is calling for help. In that case, the robot will act accordingly without alerting the aggressor. The proposed vision system uses the MediaPipe library to detect people in an image and locate the hands, from which it extracts a set of hand landmarks that identify which gesture is being made. By analysing the sequence of detected gestures, it can identify whether a person is performing the distress hand signal with an accuracy of 96.43%. (shrink)

BackgroundInformed consent is a key element of ethical clinical research. Addicted population may be at risk for impaired consent capacity. However, very little research has focused on their comprehension of consent forms. The aim of this study is to assess the capacity of addicted individuals to provide consent to research.Methods53 subjects with DSM-5 diagnoses of a Substance Use Disorder and 50 non psychiatric comparison subjects participated in the survey from December 2014 to March 2015. This cross-sectional study was carried out (...) at a community-based Outpatient Treatment Center and at an urban-located Health Centre in Spain. A binary judgment of capacity/incapacity was made guided by the MacArthur Competence Assessment Tool for Clinical Research and a clinical interview. Demographics and clinical characteristics were assessed by cases notes and the Mini-Mental State Examination, the Global Assessment Functional Scale and the Clinical Global Impression Scale.ResultsNPCs performed the best on the MacCAT–CR, and patients with SUD had the worst performance, particularly on the Understanding and Appreciation subscales. 32.7 % SUD people lacked research-related decisional capacity. There were no statistically significant differences between the groups in terms of capacity to consent to research.ConclusionsThe findings of our study provide evidence that a large proportion of individuals with SUD had decisional capacity for consent to research. It is therefore inappropriate to draw conclusions about capacity to make research decisions on the basis of a SUD diagnosis. In the absence of advanced cognitive impairment, acute withdrawal or intoxication, we should assume that addicted persons possess decision-making capacity. Thus, the view that people with SUD would ipso facto lose decision-making power for research consent is flawed and stigmatizing. (shrink)

Health‐related data uses and data sharing have been in the spotlight for a while. Since the beginning of the big data era, massive data mining and its inherent possibilities have only increased the debate about what the limits are. Data governance is a relevant aspect addressed in ethics guidelines. In this context, the European project BRIDGE Health (BRidging Information and Data Generation for Evidence‐based Health policy and research) strove to achieve a comprehensive, integrated and sustainable EU health‐information system. One of (...) the aims of the project was to evaluate the requirements to construct a data‐linkage infrastructure for the secure management of health information. In a blueprint provided for this infrastructure, the topics ethics and the intimately related governance occupied a whole section, where the recent ethics guidelines by the Council for International Organizations of Medical Sciences (CIOMS) and the World Medical Association (WMA) were referenced. We explore what has changed in the latest versions of the ethics documents adopted by CIOMS and WMA regarding the management of health data and human tissues, the appropriateness of their application in new forms of research and infrastructures as the proposed in the BRIDGE Health project, and whether society should be so concerned about this topic, in the digital era of social exchange.

The current literature shows great interest in the issue of gender diversity on boards of directors. Some studies have hypothesized a direct relationship between diversity and the value of the firm, but not many examine the intermediate mechanisms that may exert an influence on such relationships. We employ two stages of GMM estimation methodology to exhibit evidences of the relationship between gender diversity and compensation of top managers in the Spanish context. Results show that gender diversity positively affects the effectiveness (...) of boards—in terms of composition, structure, size and functioning—influencing a proper design of top managers compensation linked to company performance. Evidences suggest that legislative actions aimed at increasing the presence of women on boards of directors are justified not only for ethical reasons, but also for reasons of economic efficiency.
