This article compares two groundings of ethics: the ethical postulates of Immanuel Kant with the existential thinking of S. Kierkegaard. To achieve this goal, first, it proposes highlighting the fundamental ideas of Kantian ethics; then, secondly, highlighting Kierkegaard’s ethical stance; and finally, contrasting both approaches to identify differences and similarities. Conclusively, we can say that the pure Kantian ethical formality of duty for duty’s sake necessarily dispenses with existential and concrete content; it is an ethics that is grounded in itself, (...) that refers to itself, to the rational nature of the human being and its universality. In contrast, Kierkegaardian ethics is a Christian ethics, it is the ethics of love for one’s neighbour and, above all, for God; it is a relational and existential ethics of the single individual.

Meeting 5G high bandwidth rates, ultra-low latencies, and high reliabilities requires of network infrastructures that automatically increase/decrease the resources based on their customers’ demand. An autonomous and dynamic management of a 5G network infrastructure represents a challenge, as any solution must account for the radio access network, data plane traffic, wavelength allocation, network slicing, and network functions’ orchestration. Furthermore, federation among administrative domains (ADs) must be considered in the network management. Given the increased dynamicity of 5G networks, artificial intelligence/machine learning (...) (AI/ML) solutions are strong candidates able to learn, and take quick provisioning decisions upon fast changes in network conditions. Therefore, this chapter presents an analysis of the state-of-the-art solutions for 5G networks’ management, where AI/ML solutions are discussed and compared with traditional methods. Additionally, the chapter provides a technology overview of both standards, and existing solutions regarding the 5G network management, and directions toward the integration of AI/ML in 5G networks.

Ever since Clifford Geertz urged the “blurring of genres” in the social sciences, many scholars have considered the crossing of disciplinary boundaries a healthy alternative to rigidly maintaining them. But what precisely does the metaphor of “blurring” imply? By unpacking the varieties of visual experiences that are normally grouped under this rubric, this essay seeks to provide some precision to our understanding of the implications of fuzziness. It extrapolates from the blurring caused by differential focal distances, velocities of objects in (...) the visual field, and competing perspectival vantage points to comparable effects in the intersection of different scholarly disciplines. Arguing against the holistic implications of Geertz's metaphor, as well as the even more totalizing concept of “consilience” introduced by E. O. Wilson, it suggests that blurring implies new types of complexity between or among those disciplines. (shrink)

El siguiente informe pericial se basa en la experiencia de investigación de los firmantes en relación a las exhumaciones de fosas comunes de la Guerra Civil y la postguerra, y al conocido como “movimiento para la recuperación de la memoria histórica” que están teniendo lugar en España desde el año 2000, que ha enfatizado sus demandas sobre la suerte de los desaparecidos y ha puesto en marcha un ciclo de exhumaciones de fosas comunes derivadas de la Guerra Civil y la (...) dictadura. En este peritaje se usan las exhumaciones del siglo XXI como indicadores de la persistencia en el tiempo de las políticas y culturas del miedo instaladas en la sociedad española durante la Guerra Civil y la dictadura, más allá de las profundas transformaciones políticas e institucionales acaecidas en el país tras la muerte de Francisco Franco. Fue presentado como parte de la documentación de la demanda de Fausto Canales contra España el 15 de septiembre de 2012 en el Tribunal Europeo de Derechos Humanos. (shrink)

The aims of the study were to identify coach profiles and examine whether participants from distinct profiles significantly differed on burnout, emotions and coping. A sample of 268 athletes (Mage = 29.34; SD = 12.37), completed a series of self-reported questionnaires. Cluster analyses revealed two coach leadership profiles: (a) profile 1 with high scores of training and instruction, authoritarian behavior, social support and positive feedback, and a low score of democratic behavior; and (b) profile 2 with low levels in training (...) and instruction, authoritarian behavior, social support and positive feedback and high levels in democratic behavior. Results of MANOVAs indicated significant differences across coach profiles on reduced accomplishment, sport devaluation, happiness and seeking support and marginal differences on dejection, logical analysis, imagery/thought control, and excitement. Moreover, coach leadership profiles were not confounded by demographic variables (level of competition, gender, age, number of practice hours, professional versus no professional athletes). As a conclusion, the profile approach offered a holistic way to examine coach leadership in sport as two distinct coach profiles emerged from the cluster analyses with an unexpected combination of coach leadership dimensions.

Crisis requires society to renew itself, albeit in a disruptive way. The current Covid-19 pandemic is transforming ways of working, living, and relating to each other on a global level, suddenly and dramatically. This paper focuses on the field of education to show how higher education institutions are undergoing radical transformations driven by the need to digitalize education and training processes in record time with academics who lack innate technological capabilities for online teaching. The university system must strive to overcome (...) this situation to be competitive and provide high-quality education in a scenario of digital transformation, disruptive technological innovations, and accelerated change. To achieve these goals, this paper explains some barriers and challenges that universities encounter, as well as technological resources and methodologies they have used in the current scenario to transform higher education to face Covid-19 disruption. The discussion and conclusion synthesize significant insights that can be applied to the digitalization of education in the foreseeable future. (shrink)

University students will be our future business leaders, and will have to address social problems caused by business by implementing solutions such as social entrepreneurship ventures. In order to facilitate the learning process that will foster social entrepreneurship, however, a more holistic pedagogy is needed. Based on learning theory, we propose that students’ social entrepreneurship actions will depend on their learning about CSR and their absorptive capacity. We propose that instructors and higher education institutions can enhance this absorptive capacity by (...) exploiting Web 2.0 technologies. We tested our proposition with a sample of 425 university students using structural equation modeling and found support for the proposed relationships. (shrink)

Synthetic biologists design and engineer organisms for a better and more sustainable future. While the manifold prospects are encouraging, concerns about the uncertain risks of genome editing affect public opinion as well as local regulations. As a consequence, biosafety and associated concepts, such as the Safe-by-design framework and genetic safeguard technologies, have gained notoriety and occupy a central position in the conversation about genetically modified organisms. Yet, as regulatory interest and academic research in genetic safeguard technologies advance, the implementation in (...) industrial biotechnology, a sector that is already employing engineered microorganisms, lags behind. The main goal of this work is to explore the utilization of genetic safeguard technologies for designing biosafety in industrial biotechnology. Based on our results, we posit that biosafety is a case of a changing value, by means of further specification of how to realize biosafety. Our investigation is inspired by the Value Sensitive Design framework, to investigate scientific and technological choices in their appropriate social context. Our findings discuss stakeholder norms for biosafety, reasonings about genetic safeguards, and how these impact the practice of designing for biosafety. We show that tensions between stakeholders occur at the level of norms, and that prior stakeholder alignment is crucial for value specification to happen in practice. Finally, we elaborate in different reasonings about genetic safeguards for biosafety and conclude that, in absence of a common multi-stakeholder effort, the differences in informal biosafety norms and the disparity in biosafety thinking could end up leading to design requirements for compliance instead of for safety.

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/.

The objective was to compare the development of school tourism in the educational institutions San Pedro Chanel and Carlos Augusto Salaverry. The Leiper space approach was used. The exhibition was constituted by 200 high school students and 20 teachers. The results show that there is statistically significant differences regarding the knowledge of the tourist resources of the province of Sullana. It was concluded that educational tourism is (...) a strategy that tries to bring the student closer to knowledge, awareness and assessment of tourist resources. (shrink)

Research on adolescent-to-parent violence associates specific psychosocial characteristics with adolescents who assault their parents, whether they are within or outside the juvenile justice system, or whether these characteristics are shared by other adolescents convicted of other crimes. The aim of this paper is to compare three groups of adolescents. Those who have been sentenced for APV are compared with adolescents who have committed other crimes, and with a group who have not been involved in the justice system. The sample used (...) consists of 148 male participants between the ages of 14 and 21. A comparison is made regarding type of self-reported behavior, frequency of drug use, academic performance, exposure to violence, self-concept, and parents’ conflict resolution tactics. The results obtained indicate that adolescents with judicial measures, regardless of the crime committed, differ from those who have not been in trouble with the justice system in terms of them having suffered violence in the street, the frequency with which they use drugs and in their academic achievement. Likewise, adolescents convicted of APV differ from the other two groups in the frequency with which they are victims of violence at home, in that their mothers use the tactic of asking somebody else for help as a way of solving marital conflicts, and in having a more negative family self-concept. The results are discussed highlighting the importance of taking into account whether a sample is judicial, clinical, or community, and the specific APV behaviors which are measured. (shrink)

Although entrepreneurial intention has been widely studied using cognitive models, we still lack entrepreneurial vocation and, therefore, lack disruptive innovations. Entrepreneurship scholars have some understanding of the reasons underlying this weakness, although there is much room for improvement in our learning concerning how to promote entrepreneurship among university students, especially in the transformed context of digital technologies. This paper focuses on the early stages of start-up, and in particular seeks to evaluate what role social and psychological factors play in the (...) development of entrepreneurial intentions. Drawing on network theory, we consider the impact of social networks on entrepreneurial intention. Specifically, we analyze the influence of two types of social networks: face-to-face and online social networks, with the latter proving especially important in digital transformations. In addition, based on affective congruency theory, we relate affect with entrepreneurial intention. Particularly, we evaluate the influence of positive and negative dispositional affectivity on the formation of entrepreneurial intentions. Finally, since affect and emotions can also be related with social relationships, we analyze whether dispositional affectivities influence entrepreneurial intention through the mediation effect of social networks. Using structural equation modeling, we confirm the impact of both online and face-to-face social networks, as well as positive dispositional affectivity on entrepreneurial intention for 589 higher education students in Spain. However, negative dispositional affectivity is not seen to influence entrepreneurial intention. Furthermore, both face-to-face and online social networks are influenced by positive dispositional affectivity. Moreover, these two types of networks can even partially mediate the relationship between positive dispositional affectivity and entrepreneurial intention. Positive dispositional affectivity can thus influence entrepreneurial intention in two different ways: directly and indirectly through both face-to-face and online social networks. This study provides further insights and adds to the literature on affect, social networks, and entrepreneurial intention. From a broader perspective, we also contribute to the literature on disruptive innovations by explaining how the development of entrepreneurial intentions would have positive consequences for university students vis-à-vis achieving these disruptive innovations.

Co‐expression of two or more genes at the single‐cell level is usually associated with functional co‐regulation. While mRNA co‐expression—measured as the correlation in mRNA levels—can be influenced by both transcriptional and post‐transcriptional events, transcriptional regulation is typically considered dominant. We review and connect the literature describing transcriptional and post‐transcriptional regulation of co‐expression. To enhance our understanding, we integrate four datasets spanning single‐cell gene expression data, single‐cell promoter activity data and individual transcript half‐lives. Confirming expectations, we find that positive co‐expression necessitates (...) promoter coordination and similar mRNA half‐lives. Surprisingly, negative co‐expression is favored by differences in mRNA half‐lives, contrary to initial predictions from stochastic simulations. Notably, this association manifests specifically within clusters of genes. We further observe a striking compensation between promoter coordination and mRNA half‐lives, which additional stochastic simulations suggest might give rise to the observed co‐expression patterns. These findings raise intriguing questions about the functional advantages conferred by this compensation between distal kinetic steps. (shrink)

The present study aims to verify the psychometric properties of the Spanish versions of the Social Roles Questionnaire (SRQ; Baber & Tucker, 2006), Modern Sexism scale (MS) and Old-fashioned Sexism scale (OFS; Swim et al. Swim & Cohen, 1997). Enough support was found to maintain the original factor structure of all instruments in their Spanish version. Differences between men and women in the scores are commented on, mainly because certain sexist attitudes have been overcome with greater success in the current (...) Spanish society, while other issues, such as distribution of power in organizational hierarchies or distribution of tasks in the household, where traditional unequal positions are still maintained. In all cases, it was found that men showed greater support for sexist attitudes. The correlations between the three instruments were as expected in assessing sexist attitudes that tend to relate to each other. Eventually, we found no empirical evidence for the postulated link between sexist attitudes and traditional gender stereotypes. Our results call for the validity and effectiveness of the classic theories of gender psychology, such as gender schema theories (Well, 1981; Markus et al., 1982) and the notion of a gender belief system (Deaux & Kite, 1987; 2001).

En la actualidad se habla de la anomalía dentomaxilofacial como una enfermedad inherente a la civilización, cuya prevalencia varia en las distintas partes del mundo, el alto índice se relaciona a la heterogeneidad genética. Estas anomalías tienen una etiología multifactorial donde intervienen diversos factores internos o externos, que provocan variabilidad en su forma de presentación; cada una tiene características muy particulares y diversos grados de complejidad a la hora de ser tratadas, sin embargo poseen un aspecto común, afectan por lo (...) general la estética y la psiquis de los pacientes que las padecen. Con el objetivo de determinar afectaciones psicológicas en niños y adolescentes con anomalías dentomaxilofaciales se realizó un estudio no experimental descriptivo transversal. Se ejecutó en dos etapas y se emplearon métodos empíricos la recolección de la información a través de interrogatorio y examen clínico, incluido el Test Auto reporte vivencial para determinar la afectación psicológica del niño o adolescente. Se evidenció que los adolescentes resultaron ser afectados psicológicamente en presencia de anomalías de origen dentario. Presently, while prevalence varies in different parts of the world, dentomaxillofacial anomaly is regarded as a disease of our civilization. Its high rate is related to genetic heterogeneity. These anomalies have a multifactorial etiology since various internal or external factors that cause variability in its presentation are involved. Each of these anomalies has unique characteristics and varying degrees of complexity when being treated. However, they have a common feature: they usually affect the aesthetics and psyche of patients who suffer from them. In order to determine the psychological effects of dentomaxillofacial anomalies in children and adolescents, a non-experimental, descriptive, cross-sectional study was conducted. It was carried out in two stages and empirical methods were used for collecting information through interview and clinical examination, including Experiential Self-Report to determine the psychological effects in the child or adolescent. Through this study, adolescents were found to be affected psychologically in the presence of anomalies of dental origin. (shrink)

Tomando como marco de referencia la filosofía crítica kantiana, el artículo se plantea la cuestión del progreso moral de la humanidad. En primer lugar, examina las dificultades que en el contexto de tal filosofía presenta la pretensión de avanzar algo en lo moral.

Considera las diferentes alusiones que en la obra kantiana se encuentran en defensa de la tesis (...) que defiende el progreso moral del género humano, examinando los argumentos a favor y en contra de ellas. Finalmente, establece el estatus que debe tener en el contexto kantiano de reflexión la anticipación del posible progreso moral de la humanidad y la manera como éste habría de producirse. (shrink)

Resumen: El enfoque de máquinas nomológicas como esquema de funcionamiento de los modelos económicos supone la existencia de conjunciones constantes de eventos que tienen lugar en tanto se cumplan con determinadas cláusulasceteris paribus. Este enfoque supone causalidad del tipo lineal, una metodología del tipo macro-micro-macro, y un aislamiento respecto del entorno en el cual dicha máquina opera, lo cual lo hace congruente con el pensamiento neo-mecanicista. Consideramos que estos supuestos son cuestionables bajo el paradigma de la complejidad. En particular, dado (...) que gran parte de los fenómenos económicos responden a una causalidad no lineal, es necesario tener en consideración interacciones que no se dan en un nivel ni micro ni macro sinomeso, y que no es necesario ni conveniente hacer un aislamiento con el entorno, sino que es posible contemplarlo utilizando modelos de simulación.: The nomological machines approach as a scheme of operation of economic models presupposes the existence of constant conjunctions of events that take place as long as certain ceteris paribus clauses are fulfilled. This approach involves linear causality, a macro-micro-macro methodology, and an isolated environment in which the machine operates, which makes it consistent with the neo-mechanistic approach. We believe that these assumptions are questionable under the paradigm of complexity. Given that a large part of economic phenomena responds to non-linear causality, it is necessary to consider interactions that do not occur at a micro or macro level but rather at a meso-level, and that it is neither necessary nor desirable to isolate from the environment, but it is possible to contemplate it using simulation models.

El término estrés es una aportación de un médico húngaro llamado Has Selye (1907-1982). Su primera intuición sobre la existencia de este proceso psicológico se produjo mientras realizaba su rotatorio hospitalario al final de sus estudios de medicina.

Esto dio lugar a que el (...) resto de su vida lo dedicara al estudio y formalización del concepto de estrés. (shrink)

This volume has 41 chapters written to honor the 100th birthday of Mario Bunge. It celebrates the work of this influential Argentine/Canadian physicist and philosopher. Contributions show the value of Bunge’s science-informed philosophy and his systematic approach to philosophical problems. The chapters explore the exceptionally wide spectrum of Bunge’s contributions to: metaphysics, methodology and philosophy of science, philosophy of mathematics, philosophy of physics, philosophy of psychology, philosophy of social science, philosophy of biology, philosophy of technology, moral philosophy, social and political (...) philosophy, medical philosophy, and education. The contributors include scholars from 16 countries. Bunge combines ontological realism with epistemological fallibilism. He believes that science provides the best and most warranted knowledge of the natural and social world, and that such knowledge is the only sound basis for moral decision making and social and political reform. Bunge argues for the unity of knowledge. In his eyes, science and philosophy constitute a fruitful and necessary partnership. Readers will discover the wisdom of this approach and will gain insight into the utility of cross-disciplinary scholarship. This anthology will appeal to researchers, students, and teachers in philosophy of science, social science, and liberal education programmes. 1. Introduction Section I.

This study attempts to analyse the relationship between two key psychological variables associated with performance in sports - Self-Determined Motivation and Competitive Anxiety - through Bayesian Networks analysis. We analysed 674 university students/athletes from 44 universities that competed at the University Games in México, with an average age of 21 years (SD = 2.07) and with a mean of 8.61 years’ (SD = 5.15) experience in sports. Methods: Regarding the data analysis, first a CHAID algorithm was carried out to determine (...) the dependence links between variables, and then a Bayesian networks was developed. The validation of the BN revealed AUC values ranging from 0.5 to 0.92. Subsequently, various instantiations were performed with hypothetical values applied to the “bottom” variables. Results showed two probability trees that have extrinsic motivation and amotivation at the top, while the anxiety/activation due to worries about performance was at the bottom of the probabilities. The instantiations carried out support the existence of these probabilistic relationships, demonstrating their scarce influence on anxiety about competition generated by the intrinsic motivation, and the complex probabilistic effect of introjected and identified regulation regarding the appearance of anxiety due to worry about performance.

Synaesthesia is a condition in which one type of stimulation evokes the sensation of another, as when the hearing of a sound produces photisms, i.e. mental percepts of colours. R is a 20 year old colour blind subject who, in addition to the relatively common grapheme-colour synaesthesia, presents a rarely reported cross modal perception in which a variety of visual stimuli elicit aura-like percepts of colour. In R, photisms seem to be closely related to the affective valence of stimuli and (...) typically bring out a consistent pattern of emotional responses. The present case study suggests that colours might be an intrinsic category of the human brain. We developed an empirical methodology that allowed us to study the subject's otherwise inaccessible phenomenological experience. First, we found that R shows a Stroop effect elicited by photisms despite the fact that he does not show a regular Stroop with real colours. Secondly, by manipulating the colour context we confirmed that colours can alter R's emotional evaluation of the stimuli. Furthermore, we demonstrated that R's auras may actually lead to a partially inverted emotional spectrum where certain stimuli bring out emotional reactions opposite to the normal ones. These findings can only be accounted for by considering R's subjective colour experience or qualia. Therefore the present paper defends the view that qualia are a useful scientific concept that can be approached and studied by experimental methods. (shrink)
