Since the early 1990s, increasing attention has been paid to the impact of workplace bullying on employees’ well-being and job attitudes. However, the relationship between workplace bullying and job satisfaction remains unclear. This study aims to shed light on the nature of the bullying-job satisfaction relationship in the Italian context. As expected, the results revealed a U-shape curvilinear relationship between workplace bullying and job satisfaction after controlling for demographic variables. In contrast to the curvilinear model, the results support a negative (...) linear relationship between workplace bullying and psychological well-being, in which higher exposure to negative acts at work is associated with diminished well-being. In addition, gender and job position significantly predicted mental health scores where men and managers reported a better psychological well-being than women, blue-collar, and white-collar employees. Practical and theoretical implications are discussed according to these results. (shrink)

In recent years, supported by new scientific evidence, the conceptualization of cognitive reserve has been progressively enriched and now encompasses not only cognitive stimulating activities or educational level, but also lifestyle activities, such as leisure physical activity and socialization. In this context, there is increasing interest in understanding the role of psychological factors in brain health and cognitive functioning. In a previous study, we have found that these factors mediated the relationship between CR and self-reported cognitive functioning. In this study, (...) we have confirmed an association between two important constructs included in the psychological wellbeing and salutogenic models, “purpose in life” and “sense of coherence,” CR, as assessed using a questionnaire, and cognitive functioning, as evaluated using a comprehensive neuropsychological battery. Results from 888 middle-aged healthy participants from the Barcelona Brain Health Initiative indicate that both sense of coherence and CR were positively associated with verbal memory, reasoning and attention, working memory, and global cognition. Moreover, the relation between CR and cognitive functioning in the different domains is partially mediated by SoC. When we controlled for brain integrity, introducing into the model neurofilament light chain measures, the mediator role of SoC was confirmed for reasoning and attention and global cognition. However, purpose in life was not associated with cognitive functioning. These results reveal the central role of the SoC construct, which mediates the association between classic CR estimates and cognitive functions, potentially representing a modifiable target for interventions that aim to promote brain health.

The absence of grammatical subject and object in Parmenides' "it is/it is not" allows the reading of the verbal forms not as copulas but as names, with no implicit subject nor elided predicate. Once there are two only alternatives, contrary and excluding each other, sustaining that a 'no-name' does not grant knowledge implies identifying its opposite – "it is" – as the only name conducive to knowledge in itself, denouncing the 'inconceivability of a knowledge that does not know. If "it (...) is" is the only [name] "which can be thought/known", and "what is" is the way in which 'thought/knowledge' can be accomplished, there is no need to postulate the existence of 'anything' that is, nor of anything that can be said of "what is". Being the only name which "can be thought of/known", the unifying synthesis of "knowledge, knowing and known" in one infallible cognitive state, it is unthinkable that "what is" does not exist.

O objetivo deste texto é evidenciar o papel desempenhado pela noção de “aporia” no Parménides de Platão. Depois de ter descrito alguns dos usos da noção nos diálogos platónicos, o texto concentra-se no Parménides, analisando: 1. O debate de Sócrates com Zenão; 2. O conjunto de objeções apresentadas por Parménides ao uso por Sócrates das noções de “separação” e “participação”, focadas em particular no “Argumento do Terceiro Homem”; 3. Algumas conclusões paradoxais resultantes das oito “Hipóteses sobre o Um”, na segunda (...) parte do diálogo. Com o objetivo de sustentar a unidade da Obra, argumentando a favor do uso dos “resultados atingidos na II parte do diálogo para resolver os problemas levantados na I”, defendemos que o exercício de Parménides sobre o Um e os Outros propõe uma reformulação da dialética, denunciando a deficiência da prática atribuída a Zenão, de reduzir ao absurdo as consequências da hipótese “Se há muitos”. Em vez disso, o Eleata examina as consequências de “Se há Um”, mediante a relacionação do Um consigo próprio e com cada um dos Outros; depois dos Outros consigo próprios e com quaisquer outros, primeiro afirmando, depois negando, a hipótese.

Se realizó un estudio cuali-cuantitativo en la Comunidad Rural "El León" de la provincia de Camagüey. Se utilizó el método etnográfico y la evaluación del Análisis de la Situación de Salud en el periodo 2007-2015 con el objetivo de describir las características socio históricas y de salud de esta población, conjuntamente con profesionales de enfermería comunitaria. Se crearon instrumentos validados por expertos. Se aplicaron grupos focales, observación participante, entrevistas en profundidad a informantes clave, socioculturales, estructuradas abiertas y la cerrada para (...) combinarla con los resultados del Análisis de la Situación de Salud en el proceder cuantitativo. Se triangularon sus resultados. Se evidenció: falta de sentido de pertenencia de los pobladores, indisciplinas sociales que perjudican la comunidad y su salud, deterioro de las relaciones interpersonales, sistema eco cultural deficiente, y se identificó la necesidad de emprender otras acciones comunitarias que provoquen el cambio y modifiquen el cuadro de salud comunitaria. The quantitative and qualitative in the Community Rural accomplished a study itself "The Lion" of Camagüey's province.

Se realizó una intervención comunitaria en el asentamiento rural "El León" de Camagüey basada en los resultados de un estudio anterior. Su objetivo fue implementar un sistema de acciones socio-sanitarias colectadas en un manual que organizó contenidos de antropología socio cultural, psicología y sociología de la salud, fue conducida por profesionales de enfermería cuyo encargo social les asigna una mayor permanencia e intercambio con los pobladores. Se potenció el trabajo comunitario a partir de febrero de 2010. La investigación constituyó un (...) diseño mixto, con un estudio cuasi experimental sin grupo control combinado con métodos cualitativos. La evaluación final efectuada en el periodo 2013-2015 exhibió modificaciones positivas en indicadores del Análisis de la Situación de Salud y el entorno comunitario. Se demostró la importancia de la aplicación de las acciones comunitarias por el personal de enfermería como agente de cambio de desarrollo local y protagonista de sostenibilidad. A community intervention was carried out at the rural settlement "El León". Its objective was to implement a system of actions led by nursing professionals whose social role assigns them longer permanence and interchange with the inhabitants of the community. Community work was fostered from February 2010 with social and sanitary actions based on socio-cultural anthropology, psychology and health sociology knowledge. The investigation had a mixed design, being a quasi-experimental study without control group combined with qualitative methods. The final evaluation, which took place from 2013-2015, showed positive modifications in Health Analysis indicators and community environment. The importance of the application of community actions by nursing personnel as agents of change for local development and sustainability leaders was demonstrated. (shrink)

En este trabajo se aborda el siguiente interrogante: ¿cuáles son las condiciones de posibilidad para vivir juntos en Colombia? El autor de este trabajo señala el carácter filosófico de este problema: se trata de un punto de intersección entre dos campos de investigación de la filosofía: la ética y la política; pero además de esto, aplicado a un caso concreto ―Colombia―, con el propósito de aportar, desde la filosofía, una reflexión seria sobre problemáticas sociales que vive el país. Para resolver (...) este interrogante, se parte de la hipótesis de que los conflictos entre los seres humanos dependen, entre otras cosas, de tramas simbólicas que circulan entre los sujetos que lo sustentan; así, de esta manera, el trabajo explicitará algunas tramas simbólicas que “le dan suelo” el conflicto armado colombiano y el rol de la memoria en construcción de esa trama. En seguida, se señala la importancia de la construcción de una trama simbólica que posibilitaría la sana convivencia entre los miembros de una sociedad y las circunstancias azarosas que han dificultado que esa esfera se componga como trama simbólica.

Review of Casertano, G. _Venticinque studi sui preplatonici_.

Resumo Lida sem atenção, a avaliação do Poema de Parmênides por Nietzsche corre o risco de frustrar, mais do que estimular, os leitores não-iniciados em Filosofia. Pois, nela o filósofo não só ignora a pesquisa sua contemporânea sobre o Eleata, como insere o seu pensamento numa polêmica antiracionalista, recheada de equívocos e intuições infundadas. É nosso objetivo aqui tentar restituir credibilidade a esta avaliação, apontando as linhas que orientam o diálogo do crítico com o seu objeto tanto para o senso-comum, (...) como para o seu próprio pensamento.Carelessly read, Nietzsche’s evaluation of Parmenides frustrates rather than stimulates non-initiate readers in Philosophy. For the German philosopher ignores any current research on the Eleatic thinker, inserting his arguments in an anti-rationalist polemic, mostly based on unfounded intuitions. We aim at establishing the credibility of Nietzsche’s criticism on the grounds of common sense and of his own heraclitean influenced philosophy. (shrink)

Trait emotional intelligence concerns our perceptions of our emotional abilities, that is, how good we believe we are in terms of understanding, regulating, and expressing emotions in order to adapt to our environment and maintain well-being. In this article, we present succinct summaries of selected findings from research on the location of trait EI in personality factor space, the biological underpinnings of the construct, indicative applications in the areas of clinical, health, social, educational, organizational, and developmental psychology, and trait EI (...) training. Findings to date suggest that individual differences in trait EI are a consistent predictor of human behavior across the life span. (shrink)

One of the main challenges in medicine is to guarantee an appropriate drug supply according to the real needs of patients. Closed-loop strategies have been widely used to develop automatic solutions based on feedback variables. However, when the variable of interest cannot be directly measured or there is a lack of knowledge behind the process, it turns into a difficult issue to solve. In this research, a novel algorithm to approach this problem is presented. The main objective of this study (...) is to provide a new general algorithm capable of determining the influence of a certain clinical variable in the decision making process for drug supply and then defining an automatic system able to guide the process considering this information. Thus, this new technique will provide a way to validate a given physiological signal as a feedback variable for drug titration. In addition, the result of the algorithm in terms of fuzzy rules and membership functions will define a fuzzy-based decision system for the drug delivery process. The method proposed is based on a Fuzzy Inference System whose structure is obtained through a decision tree algorithm. A four-step methodology is then developed: data collection, preprocessing, Fuzzy Inference System generation, and the validation of results. To test this methodology, the analgesia control scenario was analysed. Specifically, the viability of the Analgesia Nociception Index as a guiding variable for the analgesic process during surgical interventions was studied. Real data was obtained from fifteen patients undergoing cholecystectomy surgery. (shrink)

This work focuses on the application of machine learning techniques to assist the clinicians in the administration of analgesic drug during general anaesthesia. Specifically, the main objective is to propose the basis of an intelligent system capable of making decisions to guide the opioid dose changes based on a new nociception monitor, the analgesia nociception index. Clinical data were obtained from 15 patients undergoing cholecystectomy surgery. By means of an off-line study, machine learning techniques were applied to analyse the possible (...) relationship between the analgesic dose changes performed by the physician due to the hemodynamic activity of the patients and the evolution of the ANI. After training different classifiers and testing the results under cross validation, a preliminary relationship between the evolution of ANI and the dosage of remifentanil was found. These results evidence the potential of the ANI as a promising index to guide the infusion of analgesia. (shrink)

O presente artigo tem como ponto central analisar, com base nos trabalhos de Michel Foucault, a respeito do Poder Disciplinar em sua atuação na área educacional, especificamente, no Ensino de Filosofia, cujo objetivo é especular sobre o referido poder, presente nas instituições de ensino. Para tratar dessa questão, que envolve o Poder Disciplinador no desenvolvimento no Ensino de Filosofia, será utilizada a metodologia da pesquisa direta bibliográfica. Nossa trabalho será desenvolvido em dois momento singulares a ideia geral sobre o poder (...) no filósofo Michel Foucault e, posteriormente, pensar o desenvolvimento do Poder Disciplinar em relação com a Educação e, consequentemente, o Ensino de Filosofia. Esse caminho acredita-se que chegará a uma compreensão do Poder Disciplinar dentro do Ensino de Filosofia, trazendo elementos e questões que contribuam na construção do sujeito pensante, seja em sua vida individual ou uma vida social, e que esse indivíduo possa transformar a sociedade.

This paper presents the manner in which the DNA, the molecule of life, was discovered. Unlike what many people, even biologists, believe, it was Johannes Friedrich Miescher who originally discovered and isolated nuclein, currently known as DNA, in 1869, 75 years before Watson and Crick unveiled its structure. Also, in this paper we show, and above all demonstrate, the serendipity of this major discovery. Like many of his contemporaries, Miescher set out to discover how cells worked by means of studying (...) and analysing their proteins. During this arduous task, he detected an unexpected substance of unpredicted properties. This new substance precipitated when he added acid to the solution and it dissolved again when adding alkali. Unexpectedly and by a mere fluke, Miescher was the first person to obtain a DNA precipitate. The paper then presents the term serendipity and discusses how it has influenced the discovery of other important scientific milestones. Finally, we address the question of whether serendipitous discoveries can be nurtured and what role the computer could play in this process. (shrink)

In this work we argue that there is no strong demarcation between pure and applied mathematics. We show this first by stressing non-deductive components within pure mathematics, like axiomatization and theory-building in general. We also stress the “purer” components of applied mathematics, like the theory of the models that are concerned with practical purposes. We further show that some mathematical theories can be viewed through either a pure or applied lens. These different lenses are tied to different communities, which endorse (...) different evaluative standards for theories. We evaluate the distinction between pure and applied mathematics from a late Wittgensteinian perspective. We note that the classical exegesis of the later Wittgenstein’s philosophy of mathematics, due to Maddy, leads to a clear-cut but misguided demarcation. We then turn our attention to a more niche interpretation of Wittgenstein by Dawson, which captures aspects of the aforementioned distinction more accurately. Building on this newer, maverick interpretation of the later Wittgenstein’s philosophy of mathematics, and endorsing an extended notion of meaning as use which includes social, mundane uses, we elaborate a fuzzy, but more realistic, demarcation. This demarcation, relying on family resemblance, is based on how direct and intended technical applications are, the kind of evaluative standards featured, and the range of rhetorical purposes at stake.

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.

Fundamentación: el desarrollo de la cultura profesional docente colaborativo se sustenta en los postulados vigotskianos, donde se concibe al profesor como un sujeto comprometido con las demandas y exigencias de la sociedad. Objetivo: socializar las categorías de análisis que se deben tener en cuenta en un colectivo docente para el desarrollo de una cultura profesional colaborativa en el proceso de formación del profesional de la educación superior. Método: se realizó un estudio etnográfico en la Universidad José Martí Pérez, (...) de Sancti Spíritus, apoyada en la metodología cualitativa y un grupo de técnicas posibilitó la recogida de la información. Resultados: se obtuvieron las categorías de análisis que están estrechamente asociadas al deber ser de un docente universitario, portador de esta cultura. Conclusiones: a partir de la coincidencia de criterios sobre los aspectos teóricos y la reflexión colectiva emergieron elementos indispensables en un colectivo para lograr la cultura profesional docente colaborativa a la cual se aspira, elaborados al tener en cuenta su estructura de contenido y forma. Background: the development of collaborative professional teaching culture is based on Vigotskian statements, where the teacher is seen as an individual compromised with the demanding and needs of the society. Objective: Socialize the analytical categories that should be taken into consideration in a teaching staff for the development of collaborative professional teaching culture in the process formation of the professional of higher education. Method: an ethnographic study was carried out in the University José Marti Pérez, from Sancti Spiritus, based on a qualitative methodology and a group of techniques that make data collection possible. Results: The analytical categories obtained were closely linked to the requirements of a university teacher that has this culture. Conclusions: starting from common criteria about theoretical aspects and group reflection, vital elements emerged in the teaching staff to get the collaborative professional teaching culture that is needed, elaborated taking into account its structure of content and form.

En este trabajo se define formamente el concepto de representacion en química utilizando homomorfismos desde estructuras algebraicas, que llamamos sistemas de tipo C, en otras estructuras especiales de símbolos muy relacionados con los que son habituales en la qímica experimental. Para la definicion de los sistemas de tipo C se ha seleccionado un conjunto minimo de relaciones y funciones, que son necesarias para expresar proposiciones significativas en química. Tambien se define un lenguaje formal de primer orden adecuado a los sistemas (...) de tipo C, que llamamos L. EI resultado principal que se demuestra es que toda representación que verifica las mismas sentencias de L que un sistema de tipo C, es necesariamente isomorfo a él. Se concluye por lo tanto que puede existir un problema linguístico subyacente en la aplicacion que de la mecaníca cuántica se hace en la química teórica.The concept of representation in chemistry bas been formallv defined by means of homomorphisms from algebraical structures, which we call type-C systems, to some special sets of symbols which can be related to the symbols ordinarily used in experimental chemistry. A minimum number of relations and functions, which would suffice to express significant propositions in chemistry, have been chosen to define type-C systems. A first order formal language L adequate to type-C systems has been defined. It has been shown that each representation that verifies the same sentences of L as a type-C system is necessarily isomorphic to it. It is concluded that a systematic study of the representation problem in chemistry is in order because a deep language problem underlies the application of quantum mechanies to chemical problems.

There have been several attempts to identify what Aristotle holds as distinctive to magnificence. The most common interpretation is that magnificence is generosity of large wealth. Irwin proposes an alternative where magnificence is generosity applied to complicated common-good projects while Curzer’s alternative is that magnificence is heroic generosity. My position is that these three positions misinterpret Aristotle’s magnificence by explicitly or implicitly rejecting some of the claims that Aristotle makes.

This work explores the later Wittgenstein’s philosophy of mathematics in relation to Lakatos’ philosophy of mathematics and the philosophy of mathematical practice. I argue that, while the philosophy of mathematical practice typically identifies Lakatos as its earliest of predecessors, the later Wittgenstein already developed key ideas for this community a few decades before. However, for a variety of reasons, most of this work on philosophy of mathematics has gone relatively unnoticed. Some of these ideas and their significance as precursors for (...) the philosophy of mathematical practice will be presented here, including a brief reconstruction of Lakatos’ considerations on Euler’s conjecture for polyhedra from the lens of late Wittgensteinian philosophy. Overall, this article aims to challenge the received view of the history of the philosophy of mathematical practice and inspire further work in this community drawing from Wittgenstein’s late philosophy.

The analysis of so-called ?strategic intentional fouls? (SIF) as well as the discussion of their validity in the normative systems of sports have a long track record. These fouls can be characterised as rule violations committed in order to be detected and which accept the corresponding sanction. However, there is an additional goal of obtaining an advantage or subsequent benefit in the competition. In fact, this practice is not infrequent and it is even occasionally accepted by the players themselves, referees, (...) judges, sports authorities and spectators. In this work I have analysed the internal structure of SIFs (the features of an axiological gap and a ?special intention?) with a view to providing a deeper understanding and stressing the differences with closely related concepts: cheating, and especially fraus legis or what in Anglo-Saxon culture is called ?spoiling the game?. Finally, I try to show some difficulties in distinguishing SIF from gamesmanship. (shrink)
