En este artículo se reconocen los aportes de la flosofía de las prácticas experimentales en torno al debate teoría – práctica y se destaca su infuencia en el papel del experimento en la enseñanza de las ciencias, particularmente en el uso por parte de los libros de texto, tomando como ejemplo un caso en electricidad.

The present article, more than to deepen in the polemic classic Popper - Kuhn regarding the progress of the science, seeks to indicate some fundamental pillars that should be kept in mind as possibility for the elaboration of a curriculum in the teaching of the sciences. It is rescued of this discus..

In the valley of the Trujala, Hornos and Guadalimar rivers in the Sierra de Segura, northeast of the province of Jaén, is an articulated system of preserved Andalusi structures that configure a landscape. To orient in a landscape, one needs a map that accurately represents the elements involved in its formation. The objective of this work is to reveal these points and to draw a chart that serves to understand and read into the palimpsest of the landscape. To achieve this, (...) an intensive prospecting of the territory is carried out to document the existing remains and an evaluation model based on Geographic Information Systems is elaborated. This process allowed for quantifying variables, obtaining statistically relevant data and classifying the information obtained in places where there is some Andalusi preexistence. The results supply useful parameters in the analytical reading of the landscape, provide quantitative knowledge about factors that connect the sites, and allow for the determination of settlement patterns. The results also reveal the mode of occupation in a territory -the ancientʿamal Šaqūra- as a reflection of the Andalusi organization in the rural world and the anthropic role that these settlements, which are associated with structures built of rammed-earth during the 12th century, have had in the landscape’s configuration.

El estudio de las presas y embalses históricos es un campo desigualmente abordado desde la historiografía, la arqueología, la arquitectura o la ingeniería civil. En la península ibérica su estudio ha estado centrado en obras de grandes dimensiones que, en general son romanas, renacentistas o posteriores. Sin embargo, pocas veces se consideran las infraestructuras andalusíes, sus formas de implantación, cómo fue la transmisión del conocimiento de su tecnología o el ámbito social y cultural en el que se desarrollaron. Suelen ser (...) vestigios que se encuentran aislados y dispersos en el ámbito rural con el que dibujan un paisaje único. Esta circunstancia dificulta su documentación e impide el estudio a fondo de estas obras como condición, previa e imprescindible, para su conocimiento. La contribución de este trabajo es el resultado de una investigación realizada sobre el paisaje generado por uno de los pocos ejemplos de presa de contención conocidos en al-Andalus de los que aún se conservan restos. Se trata de una barrera fluvial levantada, a mediados del siglo XII, en la cuenca del río Trujala en el municipio de Segura de la Sierra (Jaén); un dique que transformó un campo en un pequeño mar o albuhera.

El presente artículo ofrece una solución al problema metaético que florece en la ética humeana a propósito de la conciliación entre el cognitivismo derivado de la exigencia del General Point of View y el internalismo moral que se deriva de su argumento de la motivación. Asumiendo una descripción evolutiva en la construcción de la perspectiva evaluativa representada por el General Point of View, al tiempo que un proyectivismo epistemológico para los juicios causales que conectan las motivaciones, acciones y utilidad de (...) los distintos caracteres que surgen en el origen de la justicia, se puede conciliar -sin riesgo para la consistencia del planteamiento humeano- la existencia de individuos capaces de generar juicios morales cognitivos que derivan en una motivación moral internalista, identificada con el sentido del deber, e individuos con motivaciones claramente externalistas basadas en el uso instrumental de la razón.

RESUMEN Una vez que el foco de la reflexión pasa de las teorías ideales a la aplicación de la justicia social, centrada en las instituciones de las sociedades democráticas, se requiere prestar especial atención a los estilos de vida. Estos tienen una alta incidencia en cómo la justicia es realizada y afectan tanto a la desigualdad económica como a la disponibilidad de los recursos naturales. En nuestras sociedades es posible establecer restricciones a los estilos de vida, especialmente en aquellos casos (...) en que, por el efecto de algunas dinámicas sociales, aquellos se desacoplan de las concepciones del bien. Se defiende que, en tales casos, la base normativa que permite exigir el respeto a los estilos de vida se disuelve y por ello es posible justificar su restricción. ABSTRACT Now that the focus of reflection has shifted from ideal theories to the application of social justice, centered on the institutions of democratic societies, it is necessary to pay special attention to lifestyles, since they not only influence the realization of justice, but also have an effect on economic inequality and the availability of natural resources. In our societies, it is possible to place restrictions on lifestyles, especially in those cases in which, influenced by certain social dynamics, they disengage from conceptions of the good. The article argues that, in those cases, the normative base grounding the demand that lifestyles be respected is dissolved, thus justifying their restriction. (shrink)

Patients with strokes to the Anterior Communicating Artery pose an important challenge to rehabilitation teams due to a particular mix of cognitive and behavioral impairments. These deficits often compromise engagement with rehabilitation, learning and generalization. The goal of this article is to describe the long-term presentation of a patient with an ACoA stroke as well as her rehabilitation needs and the many challenges experienced by the rehabilitation team when attempting to facilitate functional, vocational and psychosocial recovery. Based on this case, (...) and the existing literature, a neuropsychological rehabilitation framework to understand and address the specific problems and needs of this population is proposed. This framework demands rehabilitation teams to consider: the slow pattern of recovery of this population, the interaction between cognitive and behavioral impairments, the relevance of physical and social environments, the value of personal projects and the need to include psychological and relational interventions.

The objective of the communication is to analyze the characteristics of the training projects and their relationship with the development of collaborative work in Higher Education Institutions. As a study methodology, a documentary investigation was carried out, through the review and obtaining of information in various bibliographical sources. The results indicate that training projects are a strategy aimed at training people who, in a collaborative way and with the support of new technologies, are able to mobilize their knowledge in solving (...) their most pressing context problems, so they differ from traditional educational practices, in which knowledge are transmitted by the teacher in an academic manner. In conclusion, it is necessary to continue carrying out theoretical and empirical studies that enable the educational change required by the society of our time. (shrink)

In this article, we aim to evaluate the role of robots’ personality-driven behavioural patterns on users’ intention to use in an entertainment scenario. Toward such a goal, we designed two personalities: one introverted with an empathic and self-comparative interaction style, and the other extroverted with a provocative and other-comparative interaction style. To evaluate the proposed technology acceptance model, we conducted an experiment (N = 209) at a public venue where users were requested to play a game with the support of (...) the TIAGo robot. Our findings show that the robot personality affects the acceptance model and three relevant drivers: perceived enjoyment, perceived usefulness, and social influence. The extroverted robot was perceived as more useful than the introverted, and participants who interacted with it were faster at solving the game. On the other hand, the introverted robot was perceived as more enjoyable but less useful than the extroverted, and participants who interacted with it made fewer mistakes. Taken together, these findings support the importance of designing proper robot personalities in influencing users’ acceptance, featuring that a given style can elicit a different driver of acceptance.

Surnames were obtained for the second half of the 20th century from civil and religious marriage registers on fifteen Provençal-Italian and five Italian villages of Cuneo Province, Italy. To insert in the analysis an outward comparison, surnames from two Italian villages of Turin Province, one parish of Turin, one village of Alessandria Province and one village of Asti Province were also collected. Ethnicity does not seem to be the main factor affecting the present genetic structure of the Provençal-Italians. They are (...) an open community, and evidence the end of the genetic isolation of the alpine populations. (shrink)

ABSTRACTPrior research has found a relationship between perceived facial attractiveness and perceived personal trustworthiness. We examined the time course of attractiveness relative to trustworthiness evaluation of emotional and neutral faces. This served to explore whether attractiveness might be used as an easily accessible cue and a quick shortcut for judging trustworthiness. Detection thresholds and judgment latencies as a function of expressive intensity were measured. Significant correlations between attractiveness and trustworthiness consistently held for six emotional expressions at four intensities, and neutral (...) faces. Importantly, perceived attractiveness preceded perceived trustworthiness, with lower detection thresholds and shorter decision latencies. This reveals a time course advantage for attractiveness, and suggests that earlier attractiveness impressions could bias trustworthiness inferences. A heuristic cognitive mechanism is hypothesised to ease processing demands by relying on simple a... (shrink)

We investigate the emergence of iconicity, specifically a bouba-kiki effect in miniature artificial languages under different functional constraints: when the languages are reproduced and when they are used communicatively. We ran transmission chains of participant dyads who played an interactive communicative game and individual participants who played a matched learning game. An analysis of the languages over six generations in an iterated learning experiment revealed that in the Communication condition, but not in the Reproduction condition, words for spiky shapes tend (...) to be rated by naive judges as more spiky than the words for round shapes. This suggests that iconicity may not only be the outcome of innovations introduced by individuals, but, crucially, the result of interlocutor negotiation of new communicative conventions. We interpret our results as an illustration of cultural evolution by random mutation and selection. (shrink)

Una poderosa intuición atravesaba el discurso con el que Jawaharlal Nehru, en la medianoche del 15 de agosto de 1947, se dirigía a la asamblea y, a través de la radio, a millones de indios esperanzados y jubilosos: “Hace muchos años fijamos una cita con el destino; ahora llega el momento de cumplir nuestra promesa. Cuando suene la hora de la medianoche, mientras el mundo duerme, la India despertará a la vida y a la libertad”. La estabilidad del futuro de (...) la India y su democracia solo se alcanzarían rescatando de su olvidada historia y su denostada tradición las raíces democráticas silenciadas durante tanto tiempo por la devastación intelectual producida por el colonialismo y su infame ejercicio, que encerró al país en un anquilosado arquetipo atemporal, en el que la religiosidad, la mística y la espiritualidad se establecieron como señas de identidad y orgullo de un pueblo que acabaría por identificar lo genuinamente indio con aquello que se desmarcaba de lo “presumiblemente” occidental, hasta acabar convirtiéndolo en un elemento de lucha y afirmación contra la metrópoli, desterrando de la dignidad india su pasado más racional y argumentativo.

El este ensayo, describe uno de los elementos del imaginario contemporáneo: el cansancio antropológico, según los análisis del filósofo y sociólogo Byung-Chul Han y convergente con las aportaciones del antropólogo David Le Breton. Desde este trasfondo cultural y antropológico, y con el ánimo de liberar de sus consecuencias, el logos de la fe propone la educación del deseo y la esperanza, con el fin de ampliar el horizonte de compresión de lo humano y ofrecer vías de solución.

Despite several positive features, such as extensive theoretical and empirical scope, aspects of Levelt, Roelofs & Meyer 's theory can be challenged on theoretical grounds and empirical grounds.

Social and cultural contexts influence power dynamics and shape gender perceptions, roles, and decisions regarding the management of agrobiodiversity for dealing with and adapting to climate change. Based on a feminist political ecology framework and a mixed method approach, this research performs an empirical analysis of two case studies in the northern of India, one in the Himalayan Mountains and another in the Indian-Gangetic plains. It explores context-specific influence of gender roles and responsibilities on on-farm agrobiodiversity management gendered expertise and (...) knowledge related to agrobiodiversity and gendered preferences for practices and institutional arrangements for agrobiodiversity conservation linked to adaptation to climate change. In the Himalayan mountains women actively participate in crop and seed management decisions and tasks, and maintain informal institutions for seed and services exchanges in the case of crisis, which simultaneously favours high levels of agrobiodiversity and enhances women’s social status. By contrast, in the Indio-Gangetic plains, where women from better-off households are socially secluded and women from poorer households work mainly as labourer to respond to high out-migration of men, they exercise less public control over agrobiodiversity, with their role being mainly invisible at the homestead and related to post-production tasks. We finally discuss as improved understanding of the links between gendered spaces, crops, tasks, social status, and agrobiodiversity management can facilitate the design of gender-sensitive policy interventions for conservation and adaptation to climate change.

As a 2006 Institute of Medicine report highlights, surprisingly little empirical attention has been paid to how prisoners arrive at decisions to participate in modern research. With our study, we aimed to fill this gap by identifying a more comprehensive range of factors as reported by prisoners themselves during semistructured interviews. Our participants described a diverse range of motives, both favoring and opposing their eventual decision to join. Many are well-recognized considerations among nonincarcerated clinical research participants, including a desire for (...) various forms of personal benefit, altruism, and concern about study risks and inconveniences. However, a number of influences seem unique to prisoners. Participants did not report that they were not coerced into enrolling, and they have even been under pressure not to enroll. However, many sought to enroll in order to obtain access to better health care, raising a concern about whether they were unfairly exploited. (shrink)

To assess the effectiveness of Visual Thinking Strategies in medical education curricula, a pretest–posttest experimental study design was used to evaluate the impact of participating in VTS workshops on first-year medical students. A total of forty-one intervention and sixty comparative students completed the study which included the analysis of clinical images followed by a measurement of word count, length of time analyzing images, and quality of written observations of clinical images. VTS training increased the total number of words used to (...) describe clinical images, the time spent analyzing the images, and the number of clinically relevant observations. (shrink)
