La presente es una investigación cualitativa que emplea una metodología de revisión de literatura, análisis y análisis fenomenológico. En la actualidad se ha reportado un uso no prescrito, por parte de personas sanas, de medicamentos destinados al tratamiento de padecimientos cognitivos. Dicha ingesta se ha llevado a cabo con fines potenciadores de capacidades cognitivas específicas tales como memoria, concentración y capacidad de reacción. Este empleo no recomendado de fármacos ha sido documentado mediante una serie de investigaciones y encuestas que encuentran (...) una tendencia al alza en el consumo de estas drogas sobre todo en sectores específicos de la población como el universitario en países desarrollados. El carácter potenciador de estas drogas, cuando se consumen por personas sanas lleva a la necesidad de contrastar su uso con el principio bioético de totalidad o “terapéutico”. Por lo que el presente trabajo tiene como objetivo analizar si el uso de estas sustancias puede o no ser justificado desde una perspectiva bioética a la luz de la interpretación del principio de totalidad.Se concluye que el empleo de potenciadores cognitivos puede ser permitido en personas sin patología específica pero que reporten un bajo rendimiento en determinadas áreas cognitivas o un detrimento en dichas capacidades derivado de la edad avanzada y no de una enfermedad diagnosticada. Lo anterior siempre que se cumplan criterios de seguridad y se lleven a cabo investigaciones serias y continuadas sobre sus beneficios en las poblaciones antes citadas. (shrink)

Se aborda el problema de qué es una ley científica. Se analiza la concepción tradicional hempeliana sobre la posibilidad de caracterizar una forma lógica para los enunciados de ley científica, que las distinguiría de las regularidades accidentales, concluyendo que ello no es posible. Se analiza entonces el problema de cómo es posible la predicción a partir de enunciados de ley, si no hay diferencia lógica con afirmaciones de regularidad, buscando criterios que permitan el establercimiento de afirmaciones proyectables. Correlativamente se trata (...) el problema de la normatividad de un criterio de identificación de candidatos a enunciados de ley, candidatos que ya no denominamos "lawlike statements" puesto que se ha abandonado la pretensión de que lo que determina los buenos candidatos a leyes sea su forma. A lo largo del texto se analizan de modo argumentado las posiciones filosóficas más tradicionales. Las conclusiones apuntan a la posibilidad de criterios de identificación a leyes sólo parcialmente normativos. (shrink)

This body of work is motivated by an apparent contradiction between, on the one hand, Darwin’s testimony in his autobiographical text about a supposed perceptual colour blindness before the aesthetic magnificence of natural landscapes, and, on the other hand, the last paragraph of On the Origin of Species, where he claims to perceive the forms of nature as beautiful and wonderful. My aim is to delve into the essence of the Darwinian perception of beauty in the context of the Weberian (...) concept of “disenchantment of the world”, assumed as a possible conceptual axis that enables the unravelling of the core of this contrast of perceptions. In acknowledging the theory of evolution as one of the most prominent scientific theories likely to have contributed to disenchantment, a number of questions arise: Is disenchantment compatible with aesthetic experience and sensibility before natural beauty? Was it Darwin’s disenchanted conception of the world that led him to believe he was colour blind? To answer these questions, a computer-assisted semantic analysis of lexical frequency and variability, most especially focused on aesthetic-emotional and religious or spiritual adverbs and adjectives, has been undertaken across the six editions of The Origin. The semantic analysis demonstrates that, although disenchanted, Darwin’s descriptions of, mainly, the adaptational excellence of living beings, reflect an aesthetically enriched perception of nature. It is concluded that Darwin’s perceptual colour blindness, then, might be based on a confusion rooted in the equation of equality between aesthetic sensibility in nature and the perception of its beauty as part of the vestigia Dei.

Enzyme engineering allows to explore sequence diversity in search for new properties. The scientific literature is populated with methods to create enzyme libraries for engineering purposes, however, choosing a suitable method for the creation of mutant libraries can be daunting, in particular for the novices. Here, we address both novices and experts: how can one enter the arena of enzyme library design and what guidelines can advanced users apply to select strategies best suited to their purpose? Section I is dedicated (...) to the novices and presents an overview of established and standard methods for library creation, as well as available commercial solutions. The expert will discover an up‐to‐date tool to freshen up their repertoire (Section I) and learn of the newest methods that are likely to become a mainstay (Section II). We focus primarily on in vitro methods, presenting the advantages of each method. Our ultimate aim is to offer a selection of methods/strategies that we believe to be most useful to the enzyme engineer, whether a first‐timer or a seasoned user. (shrink)

This article examines how employees form their perceptions of managerial responsibility in a concrete organizational setting. Drawing on negotiated order theory, it shows that these perceptions are the result of complex processes of social construction and negotiation, rather than the application of predetermined ethics models or norms. Employees’ perceptions appear to be unstable; they are subject to constant alterations, fluctuating with the organizational circumstances, and are likely to create considerable organizational perturbations, especially when managers make complex and ambiguous decisions. This (...) process is illustrated through an ethnographic study that analyzed the evolution of employee perceptions during a three-year crisis—one that led managers to repeatedly postpone salary payments to save jobs. The process approach adopted by the study highlights important dynamics that traditional business ethics approaches overlook, such as the fragility of the construct of managerial responsibility, which cannot be coherent unless it is constantly renegotiated among an organization’s various employee groups.

Este artículo rastrea los orígenes del choque de ideas que vertebra el debate que Michael Ruse y Robert J. Richards llevan a cabo en Debating Darwin. En esta obra, los autores discuten sobre el contexto sociocultural que alimentó la teoría de la evolución de Charles Darwin para reconocer las similitudes conceptuales que comparte con dicotomías clásicas sobre las formas humanística o científica de percibir e interpretar el mundo. El objetivo de este artículo es, pues, reflexionar, a la luz de las (...) tesis del desencantamiento del mundo y de la incidencia del conocimiento científico en las imágenes del mundo, sobre la raíz de la que brota el malestar cultural que fundamenta estas formas duales de percepción y descripción del mundo en la historia de las ideas: la supuesta incapacidad de la concepción científica del mundo para satisfacer impulsos estético-existenciales básicos de la naturaleza humana.

RESUMEN Es recurrente la tendencia a considerar a Alexander von Humboldt como autor romántico-naturalista, dada la combinación del método científico de análisis empírico de la naturaleza con su visión estético-subjetiva que posee ciertos rasgos "románticos". Un estudio del léxico empleado por Humboldt en las descripciones de la naturaleza revela, sin embargo, el predominio del lenguaje estrictamente científico e intersubjetivo sobre el subjetivo. La presencia de rasgos semánticos "románticos" no es, empero, meramente ornamental, sino que cumple una función estética que, en (...) la percepción humboldtiana de la naturaleza, es un complemento subjetivo indispensable dentro de su imagen holística del mundo. ABSTRACT Alexander von Humboldt tends to be considered a romantic-naturalist author, due to the way he combines the scientific method of empirical analysis of nature with his aesthetic-subjective view that could be said to have some "romantic" characteristics. Nonetheless, the study of the lexicon used by Humboldt to describe nature reveals the predominance of strictly scientific and intersubjective language over subjective language. Even so, the presence of "romantic" semantic traits is not merely ornamental; rather, it has an aesthetic function, which, in Humboldt's perception of nature, is an indispensible subjective complement within his holistic worldview.

The aesthetically optimistic view of life in the last paragraph of Darwin’s On the Origin of Species contrasts with the evidence in his autobiography of a supposed perceptive colour blindness to the magnificence of nature. Accepting the theory of evolution as one of the scientific theories that has contributed to disenchantment, my aim is to delve into the Darwinian perception of natural beauty and solve this contrast of perceptions within the framework of the Weberian concept of “disenchantment of the world.” (...) To do this, I have carried out a computer-assisted study of Darwin’s language focusing on the frequency of aesthetic-emotional and religious adjectives and adverbs in the six editions of the Origin. A semantic analysis of the lexicon shows that, although disenchanted, Darwin perceives nature as aesthetically enhanced. I arrive at the conclusion that Darwin’s alleged colour blindness does not come from a loss of his capacity to aesthetically perceive nature, but from his loss of religious belief. (shrink)

Teniendo en cuenta la cuestión en disputa sobre el encantamiento o el desencantamiento del mundo causado por la ciencia moderna, este artículo examina comparativamente la semántica del léxico en Journal of Researches y The Origin of Species de Charles Darwin utilizando estrategias de minería de textos. El objetivo es mostrar que existe un camino semántico directo, comenzando en Journal y culminando en Origin, que confirma una tendencia hacia un tipo de lenguaje desencantado empleado por Darwin en sus descripciones de la (...) naturaleza. Esto queda demostrado por el análisis léxico y semántico de ambos textos. Taking into accountthe disputed question about enchantment or disenchantment of the world caused by modern science, this paper comparatively examines the semantics of the lexicon of Charles Darwin’s Journal of Researches and The Origin of Species using the software package Wordsmith Tools. Its aim is to show that there is a direct semantic path, starting with the Journaland culminating in the Origin, which confirms a tendency towards a gradually disenchanting, in a non-pejorative sense, type of language used by Darwin in his descriptions of nature. This is demonstrated by the lexical and semantic analysis of the texts. (shrink)

In recent decades, there has been a proliferation among the scientific community of works that focus on Alan Turing’s contributions to the design and development of the modern computer. However, there are significant discrepancies among these studies, to such a point that some of them cast serious doubts on Alan Turing’s work with respect to today’s computer, and there are others that staunchly defend his leading role, as well as other studies that set out more well-balanced opinions. Faced with this (...) situation, the aim of this paper is to analyse the evidence existing today in order to be able to draw a conclusion about whether or not Turing anticipated the trivialisation of the modern computer memory and, likewise, if his universal a-machine is the precursor of the general-purpose computer so omnipresent today. As a result of our research, the authors conclude that Turing did indeed play a leading role in the appearance of the modern computer, although he was not the only one or the first in the field of Computing Science, albeit he was the most influential, both in scope and in depth.

The Covid-19 pandemic has led teachers to an unpredictable scenario where the lockdown situation has accelerated the shift from traditional to online educational methods, and relationships have been altered by the avoidance of direct contact with the others, with implications for their mental health. Physical activity seemed to be a factor that could prevent from mental disorders such as anxiety or depression in this peculiar situation. Therefore, the aims of this study were to explore how teachers have been affected by (...) the lockdown in respect to their mental health and their relationships in three main fields, work, family and social relationships; and to know which is the role of physical activity in the mentioned variables. For that purpose, an online survey was designed to collect quantitative and qualitative data. Results showed that indoor physical activity acts as preventive in lockdown situations, while the level of activity does not affect mental health. Also, teachers have experienced higher levels of depression and distress due to the workload generated during the lockdown. In conclusion, to prevent health problems among teachers in future similar situations it would be important to facilitate the practice of physical activity at home. Furthermore, teacher training in blended or online educational methods would be crucial for their favorable work development. (shrink)

This paper investigates whether accounting professionals’ ethical judgment is influenced by the disciplinary system established by the accounting profession in France and the United States. Our study first attempts to determine whether there is a link between the EJ of accounting professionals and the disciplinary context, in each country. It then performs a comparative analysis of the two nations. Our findings indicate that the judgment of American accounting professionals is correlated with the disciplinary decisions of the accountancy board. By contrast, (...) the judgment of French accounting professionals is independent of the disciplinary context. Whereas cross-national studies have thus far attributed differences among nations mainly to cultural distance, current research shows that non-cultural national factors should also be considered. In line with this perspective, our study suggests that institutional factors, in particular the disciplinary system, may also account for the differences between French and American accounting professionals’ ethical perceptions. We support these results by highlighting some characteristics of the countries’ respective legal systems, which may explain the divergences observed. We conclude by identifying implications for the independence of accounting professionals’ EJ and the risks associated with dissuasive disciplinary systems. (shrink)

Place?based science education engages with the laboratories of complex reality where natural processes combine with social practice, going beyond the physical world, to encompass the meanings and sense of attachment local residents feel for places. This brief report describes how a university science methods class in a primary teacher training programme situated scientific understandings in the rich cultural context of the historically rural and socio?economically disadvantaged area of Galicia in north?western Spain, where agrarian traditions continue to influence local culture. Focusing (...) on student responses to two assignments, this brief report explores how the preparation of lesson plans related to food and environmental investigation projects served to integrate aspects of the natural, social and cultural environment to foster a critical pedagogy of place.

Se abordarán detalladamente algunos de los conceptos clave que fundamentan este campo a nivel internacional, y se proporcionará un análisis del breve, pero a la vez prolífico, desarrollo que este campo de estudios ha experimentado en el Estado español durante la última década. Finalmente, se presentarán algunas de las propuestas culturales, políticas y artísticas que están enriqueciendo las ruralidades queer y ampliando sus horizontes políticos e interpretativos.

Adolescence is a stage characterized by many biological and psychosocial changes, all of which may result in a decrease in subjective well-being. It is therefore necessary to identify those factors that contribute to increased life satisfaction, in order to promote positive development among young people. The aim of this study is to examine the dynamics of a set of variables that contribute to life satisfaction. A total of 1,188 adolescents completed the Perceived Social Support from Family and Friends and Perception (...) of the School Environment Questionnaires, the Trait Meta Mood Scale, Connor-Davidson Resilience Scale-10, and Satisfaction with Life Scale for social support, emotion regulation, resilience, and life satisfaction. By applying structural equation modeling, the results reveal a direct prediction of family support, emotion regulation, and resilience on life satisfaction. Support from friends and emotion regulation was also found to explain resilience, and support from family and teachers was found to predict emotion regulation. In conclusion, emotion regulation and social support were found to indirectly affect life satisfaction among adolescents through resilience. The theoretical and practical implications of these results are discussed. (shrink)

Este artigo tem por objetivo analisar a definição de verdade em Tomás de Aquino. Para tanto, investigo dois textos que Tomás discute sobre a definição apropriada da noção de verdade. Além de defender que a manutenção da mesma definição em ambos os textos é algo filosoficamente relevante, pretendo apresentar e discutir os limites de duas opções de leitura divergentes da minha, a saber, a posição teológica de Dewan e a posição transcendental de Aertsen.

En contraposición a la predominancia cultural de lo urbano y en medio de un contexto de desenfrenado capitalismo globalizador, el VIII Congreso sobre Pensamiento Filosófico Contemporáneo se planteó el desafío de recoger algunas voces y discursos a menudo marginados por el canon del pensamiento occidental metrocentrista. A lo largo de esos tres días de octubre, en el congreso se analizaron pormenorizadamente las situaciones de sujetos, comunidades y geografías rurales, situaciones que tienden a ser activamente desescuchadas en un presente espacial que (...) encuentra la globalización, la híper-densificación de las principales zonas urbanas-metropolitanas, y el vaciamiento forzoso de las geografías rurales, como uno de sus marcos de conflicto. Estos análisis profundizaron en las necesidades específicas de dichas comunidades, arrojando luz sobre sus desafíos y ofreciendo una perspectiva crítica a propósito de la complejidad de la interacción entre lo rural y lo urbano. Desde estas inquietudes, el VIII Congreso se articuló como una plataforma a través de la que celebrar la diversidad de discursos filosóficos emergentes producidos en los marcos de lo comúnmente entendido como «rural», reconociendo su importancia crucial en la construcción de un diálogo integral sobre los desafíos que definen nuestro presente; y este monográfico es resultado de ese intercambio de saberes.

Este artículo testa la generalizada aceptación experta que detecta en _Journal of Researches _de Darwin una influencia estilístico-ideológica proveniente de las obras de Humboldt. Para ello, dado que las descripciones de la naturaleza Humboldt y Darwin deberían contener implícita la concepción de la naturaleza de cada autor, se han analizado comparativamente pasajes dedicados al análisis descriptivo del influjo del paso del tiempo sobre el paisaje geológico en _Journal _y en _Ansichten der Natur _de Humboldt. Se demuestra así que la descripción (...) de la percepción humboldtiana del tiempo deja entrever una concepción de la naturaleza romántico-naturalista que asume el tiempo y su influjo en la naturaleza como objeto estético. Por contra, a la descripción de la percepción darwiniana del tiempo subyace una concepción científico-naturalista que utiliza el concepto del tiempo como herramienta especulativa para el análisis científico del paisaje geológico.

This article considers for the first time the progressive Portuguese periodicals A Voz Feminina and O Progresso from a transnational perspective, with particular reference to contemporary debates about women’s suffrage in England as well as the wider emergence of transnational women’s networks around that time. It discusses the epistolary contact of the Principal Editor, Francisca Wood, with key radical figures such as Lydia Becker in England, Marie Goegg in Switzerland and André Léo in France, through an analysis of relevant editorials, (...) articles and correspondence received from abroad and published in the pages of the journals. Furthermore, it casts light on how Francisca Wood and her enlightened husband, William Thorold Wood, invoked the ongoing support of prominent men such as John Stuart Mill for the cause of women’s rights. Such a pioneer early feminism in Portugal was particularly remarkable in the 1860s – a context preceding the socio-political and cultural debates staged publicly in the 1871 Casino Lectures by the “Geração de 70” – which, furthermore, all but sidelined the “Woman Question.” The article concludes with a brief discussion of whether, notwithstanding Wood’s invisibility at the point of her death in 1900, she may have been behind a symbolically significant cultural intervention: the first translation of Jane Eyre into Portuguese, published in instalments from 1877 onwards in O Zoophilo.

I will place special emphasis on the lexical material (...) that Darwin uses in those paragraphs dedicated to the description of the function of Natural Selection. (shrink)

Este artículo considera el tema de las tecnologías de representación de las ruralidades queer en el cine. Las autoras llevan a cabo un análisis pormenorizado de la representación de las disidencias sexuales y de género sostenidas en y a través de espacialidades rurales tomando como objeto de estudio tres piezas fílmicas producidas en el estado español durante las últimas dos décadas, a saber, Ander (2009), 80 Egunean (2010) y Elisa y Marcela (2018). A manera de conclusión, el artículo muestra las (...) tensiones entre dos marcos interpretativos desde los que afrontar los ensamblajes en que se relacionan las ruralidades y las disidencias sexuales y de género. Estos son el enfoque de las ruralidades urbanas que produce epistemologías de carácter identitariamente fuerte, y el enfoque de las ruralidades queer que permite leer las representaciones tomadas en cuenta como figuraciones posidentitarias y subversivas de la disidencia.

The existing analysis of heterogeneous social responsibility in small and medium enterprises has considered the effects of individual factors. However, no holistic analysis has been performed on how different factors of heterogeneity interact and how they collectively affect SR in SMEs. Here, we propose a new systemic approach—employing the social capital concept—with the aim of identifying how and why SR is built diversely in SMEs. In particular, we focus on a positive and holistic perspective that integrates the factors proposed in (...) the literature into the social capital construct. Through a case study of four Spanish SMEs, this article proposes a systemic approach to the study of heterogeneous SR in SMEs. (shrink)

In the centenary year of Turing’s birth, a lot of good things are sure to be written about him. But it is hard to find something new to write about Turing.

Pharmaceutical industry marketers are confronted with specific ethical issues linked to the tension between the economic interest being pursued and the health mission of this sector. Indeed this dual mission could be problematic for them when the two objectives contradict each other. We use the concept of moral dissonance to examine how marketers in the pharmaceutical industry perceive the profit/health tension inherent in their sector and how they deal with it. Based on narratives of 18 marketers working in the pharmaceutical (...) sector, our qualitative study identifies ethical conflicts of varying intensity that generate differing degrees of moral dissonance among marketers. To cope with this moral dissonance, they use the following strategies: (1) minimize the sensitivity of their activity; (2) invoke the benefits to patients; and (3) avoid behaviors that conflict with their values.

The state of computing science and, particularly, software engineering and knowledge engineering is generally considered immature. The best starting point for achieving a mature engineering discipline is a solid scientific theory, and the primary reason behind the immaturity in these fields is precisely that computing science still has no such agreed upon underlying theory. As theories in other fields of science do, this paper formally establishes the fundamental elements and postulates making up a first attempt at a theory in this (...) field, considering the features and peculiarities of computing science. The fundamental elements of this approach are informons and holons, and it is a general and comprehensive theory of software engineering and knowledge engineering that related disciplines (e.g., information systems) can particularise and/or extend to take benefit from it (Lakatos’ concepts of core theory and protective belt theories).

Turing was an exceptional mathematician with a peculiar and fascinating personality and yet he remains largely unknown. In fact, he might be considered the father of the von Neumann architecture computer and the pioneer of Artificial Intelligence. And all thanks to his machines; both those that Church called “Turing machines” and the a-, c-, o-, unorganized- and p-machines, which gave rise to evolutionary computations and genetic programming as well as connectionism and learning. This paper looks at all of these and (...) at why he is such an often overlooked and misunderstood figure. (shrink)

Se trata de un número monográfico muy interesante, que integra un conjunto de trabajos de prestigiosos profesores universitarios—A. Clark, H. Simon, A. Gomila, J. Toribio, R. Tuomela, M. Liz, P.F. Martínez Freire, F. Broncano, C.J. Moya, P.S. Churchland, P.M. Churchland, A. Burrieza y A. Estany—sobre diversos temas candentes de la Filosofía de las Ciencias Cognitivas: cognición incorporizada, teorías computacionales de la cognición, mecanismos mentales de la intersubjetividad, responsabilidad semántica, intención conjunta y colectiva, relación entre el problema del mundo externo y (...) el problema ontológico de la experiencia subjetiva, la realidad desde la mente, relevancia filosófica de una teoría funcional de las emociones, problemas que plantean las emociones a la posibilidad de responsabilidad moral, neurobiología y conciencia, neurobiología cognitiva de las virtudes morales, tratamiento lógico de la conciencia en Inteligencia Artificial y ventajas epistémicas de la cognición socialmente distribuida. El agrupamiento de los artículos en partes diferenciadas es adecuado y coherente. Me habría gustado mucho seguirlo con orden y analizar sus contenidos con detalle; pero debo limitarme a un examen más general y a considerar simplemente las grandes tendencias o afinidades temáticas que se manifiestan a través de las páginas. Quizás lo más relevante sea la constatación efectiva de un fenómeno que se ha producido en la investigación actual sobre ciencias cognitivas y que señala A. Clark en su escrito: el redescubrimiento del cuerpo y el mundo, la crisis de una visión aislacionista de la cognición, y el surgimiento de un nuevo paradigma de patrones de actividad distribuidos a lo largo de trayectorias de procesamiento temporalmente extendidas mediante redes neuronales recurrentes. Se aprecia aquí que el énfasis se ha trasladado desde la representación simbólica hacia series reiteradas de interacciones agente-entorno. Y eso es lo prime-ro que cabría resaltar: el paulatino abandono del paradigma de representación simbólica y la atención creciente a las interacciones acopladas agente-mundo. (shrink)

El desafío del cambio climático ha impulsado un cambio de paradigma en las políticas europeas. Uno de los principales pilares de actuación son las políticas de movilidad sostenible enfocadas a la reducción del uso del vehículo privado.

Very few scientists today question the fact that information, together with matter and energy, is one of the three constructs forming the ontology of the universe. However, there is still a long way to go before in order to establish the interrelations between information and energy and information and matter, as Einstein did between matter and energy. In this paper, after introducing the energy, matter, information model, which covers the three constructs and their relationships, we illustrate real examples—two qualitative and (...) two quantitative—of the interrelations between energy and information. This closes the open question with respect to the interrelationship between energy and information. (shrink)

In this paper we present a paradigmatic example of the use in knowledge management of techniques from other fields, namely mathematical analysis. We also highlight that the Jacobi method presented here takes precedence over the better known Hungarian method.

This paper thus demonstrates the intersection between knowledge management, mathematical analysis and operational research and how taking historical perspectives (...) are important for recognising future applications of knowledge management. This results in a better understanding of knowledge management and how it can be applied in the future. It has been shown how knowledge management relates to historical mathematical principles.

In this study, a hybrid model based on intelligent techniques is developed to predict the active power generated in a bioclimatic house by a low power wind turbine. Contrary to other researches that predict the generated power taking into account the speed and the direction of the wind, the model developed in this paper only uses the speed of the wind, measured mainly in a weather station from the government meteorological agency (MeteoGalicia). The wind speed is measured at different heights, (...) against the usual measurements in others researches, which uses the wind speed and the direction measured in a weather station on the wind turbine nacelle. The prediction is performed 30 minutes ahead, what ensures that the Building Management System knows the energy generated by the low power wind turbine 30 minutes before, and it can adapt the consumption of different equipment in the house to optimize the power use. The main objective is to allow the Building Management System to optimize the uses of energy, taking into account the predicted amount of energy that will be produced and the energy consumed in the house. The developed model uses a hybrid topology with four clusters to improve the prediction, achieving an error lower than 6.5% for Mean Absolute Error measured in a final test. To perform this test, part of the original dataset was isolated from the beginning of the training process to check the model with a dataset that is not used before, simulating the model as it is receiving new data.

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)

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)
