La actividad científico-informativa constituye un componente esencial de la actividad científica. Las etapas y tareas que la integran persiguen como propósito fundamental garantizar a los investigadores la información pertinente para el desarrollo exitoso de su trabajo. De ahí la necesidad de evaluar con periodicidad su comportamiento en las bibliotecas médicas. A partir de ello, el objetivo del estudio fue sistematizar los aspectos teórico-metodológicos correspondientes a la evaluación de la actividad científico- informativa en bibliotecas médicas. Para su realización se realizó revisión (...) bibliográfica en la que se analizaron tanto documentos normativos que rigen su accionar en el sector de la salud cubano, como materiales emitidos por otras instancias nacionales e internacionales. The informative work constitutes an essential component of the scientific work. The stages and tasks that comprise it pursue as fundamental purpose to ensure relevant information in order that researchers achieve the successful development of their work. Hence the need to assess regularly their behavior in the medical libraries. Based on that, the objective of the study was to systematize the methodological aspects relating to the evaluation of the scientific-informative work at the medical libraries. In order to accomplish this a broad literature review was made which analyzed both normative documents governing its actions in the Cuban health sector, as materials issued by other national and international bodies.

La normalización de la precariedad entre las personas jóvenes está entrando en lo que parece una nueva fase. De la mano de, entre otros factores, los discursos empresariales y la teoría del capital humano, estamos asistiendo a una vuelta de tuerca en la presión sobre la juventud: ya no basta con la búsqueda «activa» de empleo, ahora hay que invertir en uno mismo como «empresario de sí mismo» y, en esta lógica, si es preciso hay que optar por la «movilidad (...) internacional». Presentamos una revisión teórica y conceptual alrededor de lo que se conoce como fuga de cerebros y su justificación discursiva. Estamos ante un proceso que probablemente dejará una marca importante en una generación que ha visto truncadas sus posibilidades de transición a situaciones estables, idealmente identificadas con el mundo adulto.Normalization of precariousness among young people is entering in a new phase. Led by, among other factors, the human capital theory, we are witnessing a twist in pressure on young people: it is no longer enough with «active» job search, now you have to invest in yourself as entrepreneur of yourself’ and in this logic, maybe young people must choose for the «international mobility», which is represented as a cosmopolitan option. We present a theoretical and conceptual review around what is known as brain drain and its discursive justification. We are facing a process that will probably leave a significant mark on a generation whose chances of transition to stable situations have been truncated, ideally identified with the adult world.

O presente artigo trata da influência exercida pela filosofia kantiana na actualidade a partir da chamada crise da Modernidade ilustrada. Os autores começam por analisar o posicionamento original kantiano, incidindo especialmente na sua concepção do criticismo e do transcendentalismo. Esta análise é feita a partir da perspectiva da aberta pela Kritik der Urteilskraft enquanto marco do sistema da razão, capaz de incorporar a finitude da mesma. Seguidamente são analisadas a recepção e a transformação do pensamento kantiano a partir de duas (...) correntes filosóficas actuais: o Racionalismo Crítico de Karl Popper e Hans Albert, e a Pragmática Transcendental da linguagem de KarlOtto Apel. Em ambos os casos se compara o seu modo próprio de incorporar as noções de crítica e transcendentalidade com a concepção original de Kant. (shrink)

This article explores the philosophy of Alain Badiou from the vantage point of the concepts of the localization, delocalization, and relocalization of the void as thematized through literary arts, religion, emancipatory politics, and the subject of psychoanalysis. In short, these moments around the void characterize the processes through which truth is processed and seen through their full realization by a philosophical engagement across the various conditions in which these truths occur. The localization of a void is the naming of an (...) indiscernible element that is incommensurable to the rubric of constructible knowledge, sense and meaning which could saturate the space of truth. Thus, the naming that localizes the void acts as a subtraction of the invariant in the variance of situation such that across various points in space and time, we are still able to subtract the universal as the invariant not just as the fidelity to the localized truth but also as the resurrection of truth upon its relocalization at a different place and a different time. At its core, this article is concerned with truth, why truth is persistent, and why we have to struggle to articulate the truth that we are trying to be faithful to again and again with each instance that truth risks being covered-over and obscured.

In the paper we obtain a new characterization of the BCK-algebras which are subdirect product of BCK-chains. We give an axiomatic algebraizable extension of the BCK-calculus, by means of a recursively enumerable set of axioms, such that its equivalent algebraic semantics is definitionally equivalent to the quasivariety of BCK-algebras generated by the BCK-chains. We propose the concept of "linearization of a system" and we give some examples.

In this paper an algebraic version for temporal algebras of the logical filtrations for modal and temporal logics is analysed. A structure theorem for free temporal algebras and also some results with regard to the variety of temporal algebras are obtained.

In this paper the structure of pretemporal algebra is used to study some aspects of temporal algebras and modal algebras. The paper contains a computational approach to finite temporal algebras and a general splitting theorem for finite temporal algebras.

Psychosocial work factors are implicated in the development of stress and job satisfaction. This relationship has been scarcely studied in so-called singular activities, as is the case of professional drivers. This cross-sectional study of 601 professional drivers assesses psychosocial risks and job satisfaction using Copenhagen Psychosocial Questionnaire and Overall Job Satisfaction questionnaire models. The values of the psychosocial scales of professional drivers were compared with thresholds values of the Spanish working population. The relationships of the psychosocial scales with the level (...) of job satisfaction were examined using logistic regression models, adjusted for age, gender, length of driving license and years of experience. In general, professional drivers have an unfavorable psychosocial environment compared to the average Spanish workers. The relationship between psychosocial scales and job satisfaction is observed, with the most influential variables being the meaning and development of work, integration in the company, social relations, esteem and level of psychological demands.

La investigación en tecnología con fines militares se ha profundizado en las últimas décadas debido al desarrollo de la inteligencia artificial, como puede observarse en los drones o vehículos aéreos no tripulados. El despliegue de estos artefactos en el campo de batalla está suscitando importantes problemáticas y controversias éticas. En ese sentido, el propósito de esta trabajo gira en torno a la necesidad de plantear una reflexión ética sobre el diseño y finalidad de los drones desde el modelo de Investigación (...) e Innovación Responsables, con el objetivo de reorientar su empleo hacia fines humanitarios y cívicos.

Tras los procesos de investigación e innovación en el campo de la inteligencia artificial subyacen relaciones políticas que pueden ser sometidas a una reflexión ética. La ciencia cívica pone en valor la comunicación como una herramienta para fortalecer los vínculos democráticos entre los entornos científicos y la ciudadanía. En este sentido, el propósito de este trabajo gira en torno a la formulación del concepto de inteligencia artificial responsable impulsado desde los laboratorios abiertos como un espacio deliberativo para hacer posible el (...) cultivo de habilidades cívicas y democráticas en el contexto tecnológico. Proporcionando de ese modo una orientación pragmática y fronética de los sistemas artificiales hacia los Objetivos de Desarrollo Sostenible. Este trabajo es el resultado de una investigación bibliográfica. (shrink)

El propósito del presente trabajo consiste en poner en valor un modelo de innovación abierto y responsable para el desarrollo tecnológico. Este modelo permite poner en tela de juicio la cultura científica que entiende el proceso de generación de conocimiento en términos de monopolios y oligopolios, privilegiando en enfoque de arriba hacia abajo. Este enfoque presenta un déficit comunicativo entre los expertos tecnólogos y los demás grupos de interés y afectados por la tecnología. En ese sentido, es importante promover una (...) investigación e innovación responsables, estableciendo de ese modo un hilo comunicativo entre lo deseable y lo aceptable. Además, las tecnologías despliegan su actividad en contextos morales y por lo tanto presentan una dimensión política y social que exige llevar a cabo una evaluación ética. Este artículo es el resultado de una investigación bibliográfica. (shrink)

Ensayos es el título de una pintura donde su autor se representa modalizando su “yo” como sujeto y tema. En esta misma operación se elabora una pintura de la humana condición, una moral. Se trata de responder a dos cuestiones: ¿cómo es posible en un autorretrato de tinta un estudio de los comportamientos del “hombre en general”? y ¿cómo es posible, para un autor del siglo XVI, construir una moral, que rebasa el nivel de las costumbres y las convenciones, sin (...) una representación comprensiva y, por ende, correlativa a su escepticismo?

En el pensamiento de Foucault se encuentra la composición de una nueva noción de crítica, susceptible de aclarar la cuestión de las relaciones sujeto y verdad y la práctica de su propio pensamiento. La crítica puede leerse como modo de ser y como operador del pensamiento, y de un pensamiento que se toma en su existencia misma, no en «función de documento», sino en su «existencia de monumento», como práctica histórico-crítica. Interrogamos: si, para Foucault, no hay práctica alguna exterior a (...) la verdad, ¿el pensamiento es susceptible de definirse como práctica histórico-crítica de la verdad -de la «verdad-ritual»-?

Montaigne compone una ética moderna definida por el ejercicio de su pensamiento autocritico que acompañado de un método filosófico aborda la construcción de sÍ mismo como una "manera" filosófica. Las reflexiones intentan responder simultáneamente a dos cuestiones: ¿cómo le es posible proveerse de una ética que le permita una existencia ordenada y sensata, cuando la condición humana está signada por el desorden y la extravagancia? ¿Cómo le es posible fundar una ética moderna -antes que Descartes- con una posición escéptica?

En los últimos treinta años se ha transitado desde una concepción del capital humano como una macromagnitud económica a una idea de capital humano corporeizada en el individuo. Hemos asistido a una progresiva infiltración de dicha ideología del capital humano también en la vida de la juventud precaria. Nos centramos aquí en los jóvenes universitarios, para quienes el capital humano, ya de forma hegemónica, dirige y marca sus recorridos laborales y vitales. El análisis de los discursos de estos jóvenes nos (...) permitirá explorar desde la imposición de la lógica de la movilidad laboral, a la sujeción a las formas de "emprendedor de sí mismo" y a la normalización, como parte del proceso de incorporación de capital humano, de formas de empleo progresivamente al margen de los derechos y garantías laborales clásicas del trabajo salariado.In the last thirty years it has been gone from a conception of the human capital as an economic macro magnitude to an idea of human capital embodied in the individuals. We have been witnesses of the progressive infiltration of this ideology of the human capital also in the life of precarious youth. We focus in the university young people, for those who the human capital, already of hegemonic form, directs and marks its labour and vital routes. The analysis of the discourses of these young people will allow us to explore the imposition of the logic of labour mobility, the subjection to the forms of «entrepreneur of itself» and also the normalization of forms of work progressively excluded from the rights and classic labour guarantees as a part of the process of incorporation of human capital.

Introduction: Loss of employment is an experience that is lived and interpreted differently depending on a series of individual variables, including the psychological resources available to the affected person, as well as their perception of their degree of employability. Losing one’s job can be one of the most painful and traumatic events a person has to withstand. Following a dismissal, the worker needs to overcome a period of emotional adaptation to the loss. But that period of grieving can also condition (...) the process of job search of the person, and be influenced by different variables, highlighting the age and work experience. The objective of this study is to analyze the relationship between intensity and type of affliction due to the loss of employment in older workers and their level of employability. Method: We carried out a descriptive, analytical, cross-sectional study. The sample consisted of 140 unemployed participants, from 19 to 65 years of age, users of job Orientation in the Public Employment Service of Andalusia (España). Of the total participants, 66 were unemployed and over 45 years of age. They all took the Labour Insertion Potential Assessment Test, and the Texas Inventory revised adapted to job loss Results: Significant differences are shown in the grieving process due to loss of employment between both groups, with the older unemployed living the process more intensely. In relation to the employability potential, differences are found between both groups in terms of availability, perceived difficulties and fears. Interrelationships between total grieving intensity and the importance that older jobseekers give to work are also indicated. Conclusion:Loss of employment and the psychological and health consequences of this situation are identified with those that arise in the grieving process. Older workers present a series of features that determine that their job loss grieving process is more intense and lasts longer than that of other younger workers, regardless of whether the job loss was recent or not. On the other hand, it is shown that the intensity of grieving is related to the decrease of certain variables that are part of the concept of employability. (shrink)

Nowadays, the quality standards of higher education institutions pay special attention to the performance and evaluation of the students. Then, having a complete academic record of each student, such as number of attempts, average grade and so on, plays a key role. In this context, the existence of missing data, which can happen for different reasons, leads to affect adversely interesting future analysis. Therefore, the use of imputation techniques is presented as a helpful tool to estimate the value of missing (...) data. This work deals with the academic records of engineering students, in which imputation techniques are applied. More specifically, it is assessed and compared to the performance of the multivariate imputation by chained equations methodology, the adaptive assignation algorithm based on multivariate adaptive regression splines and a hybridization based on self-organisation maps with Mahalanobis distances and AAA algorithm. The results show that proposed methods obtain successfully results regardless the number of missing values, in general terms. (shrink)

En este artículo presentamos las principales corrientes de la Filosofía Experimental y atendemos a una de las críticas más severas a la que se ha sometido este reciente programa de renovación metodológica. Según Antti Kauppinen la Filosofía Experimental está condenada al fracaso porque no puede obtener mediante sus métodos el tipo de intuiciones que interesan a los filósofos –las intuiciones robustas del hablante competente. Aun aceptando parte de las críticas de Kauppinen, en este artículo sostenemos, en primer lugar, que la (...) supuesta incapacidad de la Filosofía Experimental para acceder a las intuiciones robustas de los hablantes tiene que ver en gran medida con los métodos experimentales empleados hasta ahora por los filósofos experimentales. En segundo lugar, defendemos que el proyecto de reforma llevado a cabo desde la Filosofía Experimental resultará viable solo si se adoptan una serie de consejos metodológicos procedentes de la economía experimental. Únicamente entonces podrán los experimentalistas responder con éxito a la objeción de Kauppinen. (shrink)

Sociotype is a concept that allows a more comprehensive understanding about biosociology of undiagnosed rare diseases (URD). Sociotype is related to a genotype and a phenotype and it is an expression of the individual life world in society. In this paper, semiotic and hermeneutic analysis of papers published and selected about URD is developed. Te perspective followed in this research is aligned with the works of Barbieri and Peirce. Papers with the most social content have been selected and those with (...) a more biomedical content have been rejected. Te semiotics analysis has been divided in genotypic, phenotypic and sociotypic, and related to the hermeneutical perspective. It has been possible to understand the basis of semiotics elements of URD. Te general conclusion is that URD is a particular sociotype with a determined set of social characteristics. Tis paper opens research on the biosemiotic and hermeneutic perspective about URD. (shrink)

AI research is being challenged with ensuring that autonomous agents learn to behave ethically, namely in alignment with moral values. Here, we propose a novel way of tackling the value alignment problem as a two-step process. The first step consists on formalising moral values and value aligned behaviour based on philosophical foundations. Our formalisation is compatible with the framework of (Multi-Objective) Reinforcement Learning, to ease the handling of an agent’s individual and ethical objectives. The second step consists in designing an (...) environment wherein an agent learns to behave ethically while pursuing its individual objective. We leverage on our theoretical results to introduce an algorithm that automates our two-step approach. In the cases where value-aligned behaviour is possible, our algorithm produces a learning environment for the agent wherein it will learn a value-aligned behaviour. (shrink)

In the context of solving large distributed constraint optimization problems, belief-propagation and incomplete inference algorithms are candidates of choice. However, in general, when the problem structure is very cyclic, these solution methods suffer from bad performance, due to non-convergence and many exchanged messages. As to improve performances of the MaxSum inference algorithm when solving cyclic constraint optimization problems, we propose here to take inspiration from the belief-propagation-guided decimation used to solve sparse random graphs. We propose the novel DeciMaxSum method, which (...) is parameterized in terms of policies to decide when to trigger decimation, which variables to decimate and which values to assign to decimated variables. Based on an empirical evaluation on a classical constraint optimization benchmarks, some of these combinations of policies, using periodic decimation, cycle detection-based decimation, parallel and non parallel decimation, random or deterministic variable selection and deterministic or random sampling for value selection, outperform state-of-the-art competitors in many settings.

One of the objectives in the field of artificial intelligence for some decades has been the development of artificial agents capable of coexisting in harmony with people and other systems. The computing research community has made efforts to design artificial agents capable of doing tasks the way people do, tasks requiring cognitive mechanisms such as planning, decision-making, and learning. The application domains of such software agents are evident nowadays. Humans are experiencing the inclusion of artificial agents in their environment as (...) unmanned vehicles, intelligent houses, and humanoid robots capable of caring for people. In this context, research in the field of machine ethics has become more than a hot topic. Machine ethics focuses on developing ethical mechanisms for artificial agents to be capable of engaging in moral behavior. However, there are still crucial challenges in the development of truly Artificial Moral Agents. This paper aims to show the current status of Artificial Moral Agents by analyzing models proposed over the past two decades. As a result of this review, a taxonomy to classify Artificial Moral Agents according to the strategies and criteria used to deal with ethical problems is proposed. The presented review aims to illustrate (1) the complexity of designing and developing ethical mechanisms for this type of agent, and (2) that there is a long way to go (from a technological perspective) before this type of artificial agent can replace human judgment in difficult, surprising or ambiguous moral situations.

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)

The interest of assigning homework is frequently discussed due to its alleged low impact on student achievement. One of the current lines of research is to emphasize the quality of student homework engagement rather than the amount of time spent on homework. The aim of this study was to determine (a) the extent to which students’ prior achievement affects their homework engagement (i.e., time spent, time management, and amount of teacher-assigned homework done), and (b) how students’ intrinsic motivation towards homework (...) may mediate or moderate the relationship between prior achievement and the homework engagement variables. A large sample of students from the first four years of Secondary Education (N = 1899) completed questionnaires. The results showed that intrinsic motivation partially mediates, but does not moderate, the effect of prior achievement on the three variables related to homework engagement (time spent, time management, and amount of teacher-assigned homework done). These results highlight the importance of considering both students’ current level of achievement and their motivation towards homework engagement when assigning homework. (shrink)
