The systemic complexity of sustainable development imposes a major cognitive challenge to students’ learning. Faculty can explore new approaches in the classroom to teach the topic successfully, including the use of technology. We conducted an experiment to compare the effectiveness of a simulation vis-à-vis a case-based method to teach sustainable development. We found that both pedagogical methods are effective for teaching this concept, although our results support the idea that simulations are slightly more effective than case studies, particularly to teach (...) its multidimensional and inter-temporal nature. Therefore, our findings suggest the use of both simulations and case studies as pedagogical tools to convey the main ideas associated with sustainable development. (shrink)

The US neutrino community gathered at the Workshop on the Intermediate Neutrino Program at Brookhaven National Laboratory February 4-6, 2015 to explore opportunities in neutrino physics over the next five to ten years. Scientists from particle, astroparticle and nuclear physics participated in the workshop. The workshop examined promising opportunities for neutrino physics in the intermediate term, including possible new small to mid-scale experiments, US contributions to large experiments, upgrades to existing experiments, R&D plans and theory. The workshop was organized into (...) two sets of parallel working group sessions, divided by physics topics and technology. Physics working groups covered topics on Sterile Neutrinos, Neutrino Mixing, Neutrino Interactions, Neutrino Properties and Astrophysical Neutrinos. Technology sessions were organized into Theory, Short-Baseline Accelerator Neutrinos, Reactor Neutrinos, Detector R&D and Source, Cyclotron and Meson Decay at Rest sessions.This report summarizes discussion and conclusions from the workshop.

Detecting sensitive information considering privacy is a relevant issue on Online Social Networks (OSNs). It is often difficult for users to manage the privacy associated with their posts on social networks taking into account all the possible consequences. The aim of this work is to provide information about the sensitivity of the content of a publication when a user is going to share it in OSN. For this purpose, we developed a privacy-assistant agent that detects sensitive information. Based on this (...) information, the agent provides a message through a nudge mechanism warning about the possible risks of sharing the message. To avoid being annoying, the agent also considers the user’s previous behaviour (e.g. if he previously ignored certain nudges) and adapts the messages it sends to give more relevance to those categories that are more important to the user from the point of view of the privacy risk. This agent was integrated into the social network Pesedia. We analysed the performance of different models to detect a set of sensitive categories (i.e. location, medical, drug/alcohol, emotion, personal attacks, stereotyping, family and association details, personal details and personally identifiable information) in a dataset of tweets in Spanish. The model that obtained the best results (i.e. F1 and accuracy) and that was finally integrated into the privacy-assistant agent was transformer-based. (shrink)

Las reflexiones en torno a la escritura de acontecimientos traumáticos como fueron las dictaduras chilenas y argentinas genera una serie de aporías que podrían resumirse en las siguientes cuestiones: ¿cómo comprender aquello que sobrepasa toda comprensión?, ¿cómo narrar lo inenarrable?, ¿cómo recomponer los testimonios de acontecimientos desprovistos de testigos? En este ensayo me propongo explorar estos asuntos en relación con cuatro novelas que parten de la ausencia, en tanto el pasado de la dictadura -identificado no solo como irrepresentable, también como (...) incomprensible- origina una falta o carencia de la que emerge la escritura. Concretamente se analizarán las novelas de los hijos, quienes eran aún niños durante la dictadura y por ello la vivieron de manera indirecta a través de sus padres: Formas de volver a casa (2011) de Alejandro Zambra, Una misma noche (2012) de Leopoldo Brizuela, El espíritu de mis padres sigue subiendo en la lluvia (2011) de Patricio Pron y Fuenzalida (2010) de Nona Fernández.

Resumen Este artículo ofrece una lectura de la pintura renacentista según los principios establecidos por Leon Battista Alberti, uno de los primeros teóricos de la perspectiva en cuyo Tratado de pintura se refiere al cuadro como “una ventana abierta a la historia”. El concepto de historia empleado por Alberti, que se presta a numerosas interpretaciones, es abordado a partir de las reflexiones de Erwin Panofsky en torno a la perspectiva como “forma simbólica”, avanzando hacia una hipótesis en torno al carácter (...) simbólico de la configuración y representación del tiempo en el cuadro-ventana albertiano.This paper offers a reading of the renaissance painting according to the principles established by Leon Battista Alberti, one of the first theorists of perspective in painting which Trattato della pittura define the frame of the painting as “an open window into history”. The concept of history employed by Alberti, which lends itself to many interpretations, is approached from the reflections of Erwin Panofsky about the prospect as “symbolic form”, moving towards a hypothesis about the symbolic nature of the configuration and representation of time in the alberti’s window.

El presente artículo traza una revisión de lo que actualmente se entiende por ciencia, arte y tecnología para poder mostrar cómo la ingeniería moderna y en particular la ingeniería civil, es un compendio de los tres componentes, siendo el medio necesario para la sostenibilidad ambiental y social hoy requeridas. La ingeniería se enfrenta a problemas y sigue un método, que no es exclusivamente científico. Necesita la aproximación al arte y el ingeniero debe contar con una formación humanística, de contenido humano (...) significativo, que lo proteja del excesivo tecnicismo ya que se mueve en el entorno de lo real, no del laboratorio. La investigación bibliográfica y documental de la historia de los distintos conceptos permite pensar la ingeniería desde la filosofía y tiene como objetivo proponer que la llamada perspectiva CATI3 (Ciencia-Arte-Tecnología-Ingeniería) sea el vehículo de aproximación al concepto de ingeniería e interpretar sus relaciones con la tecnología, el arte y la ciencia en su proyección a la sociedad.

The compact and, with \ M\, very massive object located at the center of the Milky Way is currently the very best candidate for a supermassive black hole in our immediate vicinity. The strongest evidence for this is provided by measurements of stellar orbits, variable X-ray emission, and strongly variable polarized near-infrared emission from the location of the radio source Sagittarius A* in the middle of the central stellar cluster. Simultaneous near-infrared and X-ray observations of SgrA* have revealed insights into (...) the emission mechanisms responsible for the powerful near-infrared and X-ray flares from within a few tens to one hundred Schwarzschild radii of such a putative SMBH. If SgrA* is indeed a SMBH it will, in projection onto the sky, have the largest event horizon and will certainly be the first and most important target for very long baseline interferometry observations currently being prepared by the event horizon telescope. These observations in combination with the infrared interferometry experiment GRAVITY at the very large telescope interferometer and other experiments across the electromagnetic spectrum might yield proof for the presence of a black hole at the center of the Milky Way. The large body of evidence continues to discriminate the identification of SgrA* as a SMBH from alternative possibilities. It is, however, unclear when the ever mounting evidence for SgrA* being associated with a SMBH will suffice as a convincing proof. Additional compelling evidence may come from future gravitational wave observatories. This manuscript reviews the observational facts, theoretical grounds and conceptual aspects for the case of SgrA* being a black hole. We treat theory and observations in the framework of the philosophical discussions about “realism and underdetermination”, as this line of arguments allows us to describe the situation in observational astrophysics with respect to supermassive black holes. Questions concerning the existence of supermassive black holes and in particular SgrA* are discussed using causation as an indispensable element. We show that the results of our investigation are convincingly mapped out by this combination of concepts. (shrink)

In 2012, a U.S. Institute of Medicine report called for a different approach to health care: “Left unchanged, health care will continue to underperform; cause unnecessary harm; and strain national, state, and family budgets.” The answer, they suggested, would be a “continuously learning” health system. Ethicists and researchers urged the creation of “learning health organizations” that would integrate knowledge from patient‐care data to continuously improve the quality of care. Our experience with an ongoing research study on atrial fibrillation—a trial known (...) as IMPACT‐AFib—gave us some insight into one of the challenges that will have to be dealt with in creating these organizations. Although the proposed educational intervention study placed no restrictions on what providers and health plans could do, the oversight team argued that the ethical principle of beneficence did not allow the researchers to be “bystanders” in relation to a control group receiving suboptimal care. In response, the researchers designed a “workaround” that allowed the project to go forward. We believe the experience suggests that what we call “bystander ethics” will create challenges for the kinds of quality improvement research that LHOs are designed to do. (shrink)

Charles Taylor es comúnmente identificado como uno de los padres fundadores del comunitarismo teórico, pero tal identificación no da cuenta de la amplitud del pensamiento del filósofo canadiense. A través de este trabajo de investigación pretendemos articular la filosofía de Taylor partiendo del proyecto filosófico que explícitamente inicia en sus primeros trabajos, a saber, la configuración de una antropología filosófica, a través de la cual abordaremos los grandes temas que han ocupado su vida -ética, política y religión- en la puesta (...) en marcha de una filosofía con intenciones puramente prácticas.Charles Taylor is commonly identified as one of the founding fathers of theoretical communitarianism, but such identification does not realize the extent of his thinking. Through this research, we try to articulate the Taylor's philosophy from his philosophical project, that he explicitly started in his early work, namely, the configuration of a philosophical anthropology, through which we will address the major issues that have occupied his life - ethics, politics and religion- in the implementation of a philosophy with purely practical intentions.

The purpose of the article was to determine the relationship between the organizational culture and the institutional management of the "Enrique López Albújar" Educational Institution, Piura. Work is worked under a quantitative approach, descriptive and correlational scope, 40 teachers participated as a sample. Among the results, it was found that there is no significant relationship between organizational culture and institutional management, which did not allow validating the research hypothesis; However, a significant relationship between norms and customs with institutional management was (...) found; which concludes in compliance with the norms and good customs based on values.

Retrieval practice, relative to further study, leads to long-term memory enhancement known as the “testing effect.” The neurobiological correlates of the testing effect at retrieval, when the learning benefits of testing are expressed, have not been fully characterized. Participants learned Swahili-English word-pairs and were assigned randomly to either the Study-Group or the Test-Group. After a week delay, all participants completed a cued-recall test while undergoing functional magnetic resonance imaging. The Test-Group had superior memory for the word-pairs compared to the Study-Group. (...) While both groups exhibited largely overlapping activations for remembered word-pairs, following an interaction analysis the Test-Group exhibited differential performance-related effects in the left putamen and left inferior parietal cortex near the supramarginal gyrus. The same analysis showed the Study-Group exhibited greater activations in the dorsal MPFC/pre-SMA and bilateral frontal operculum for remembered vs. forgotten word-pairs, whereas the Test-Group showed the opposite pattern of activation in the same regions. Thus, retrieval practice during training establishes a unique striatal-supramarginal network at retrieval that promotes enhanced memory performance. In contrast, study alone yields poorer memory but greater activations in frontal regions. (shrink)

La fenomenología de la religión es una de las ciencias de las religiones surgida en el siglo XIX. Tras una época dorada, las dificultades epistemológicas y los debates suscitados en torno al estatuto del saber la abocaron a una profunda crisis interna. En la actualidad, existen dos formas de entender la fenomenología de la religión: la primera, como historia comparada de las religiones, centrada en la descripción y clasificación de los fenómenos religiosos; la segunda, como fenomenología hermenéutica, centrada en la (...) comprensión del fenómeno religioso. Ambas corrientes constituyen dos visiones divergentes de la fenomenología de la religión. Sin embargo, podrían concebirse como dos fases fenomenológicas convergentes que apuntan a la consolidación de una antropología filosófica de la religión. En este artículo, analizamos el objetivo, los principales representantes, las dificultades epistemológicas y los logros de cada una de estas for-mas de comprender la fenomenología de la religión y su posible conjugación en la configuración de una filosofía fenomenológica de la religión.The phenomenology of religion is one of the sciences of religions emerged in the 19th century. After a golden age, the epistemological difficulties, and the debates about the status of knowledge led to a deep internal crisis. At present, there are two ways of understanding the phenomenology of religion: the first, as a com-parative history of religions, focused on description and classification of religious phenomena; the second, as a hermeneutical phenomenology, focused on the understanding of religious phenomena. Both currents constitute two divergent views of phenomenology of religion. However, they can be conceived as two convergent phenomenological phases that point to the consoli-dation of a philosophical anthropology of religion. In this paper, we analyze the goal, main representatives, epistemological difficulties and achievements of each of these ways of understanding the phenomenology of religion and its possible conjugation in the configuration of a phenomenological philosophy of religion.

The World Health Organization, in its last review of its International Classification of Diseases, established a new classification for chronic pain. Among the principal categories, of particular interest is chronic primary pain as a new type of diagnosis in those cases in which the etiology of the disease is not clear, being termed as chronic primary visceral pain when it is situated in the thorax, abdomen, or pelvis. Due to the novelty of the term, the objective of the systematic review (...) was to examine the psychopathological and neuropsychological disorders associated with chronic primary visceral pain. We carried out a search of the scientific literature following the PRISMA directives using the Pubmed, Medline, PsycInfo and Scopus databases. A total of 33 articles were selected after applying the inclusion and exclusion criteria. The analysis of the studies showed that most persons with chronic primary visceral pain suffer from at least one psychological disorder; the most prevalent being anxiety, depressive or somatoform disorders. The most frequent psychopathological symptoms are anxiety, depression and somatization. Similarly, the findings are insufficient to determine the existence of deficits in the domains of executive functioning, memory and intelligence. However, the existence of attention biases does seem to be clear. This review supposes a starting point for conceptualizing chronic primary visceral pain. It is necessary to continue further research so as to obtain a better understanding of this pathology and the disorders associated. (shrink)

In this special issue we explore practices of scientific inquiry into human populations in Latin America in order to generate new insights into the complex historical and sociopolitical dynamics that have made certain human groups integral to the production of scientific knowledge in and about the region. In important contributions, other scholars have shown that the science of human difference is racist and all too often has been a mediator of development ideologies. To further unpack these arguments we focus attention (...) on the complex interaction between scientists and the populations they study. We explore cases from across the fields of evolutionary biology, demography, epidemiology... (shrink)

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

El presente artículo busca profundizar las formas en que migrantes peruanos en Chile habitan su espacio privado desde una perspectiva de cultura material, a través del análisis de las posesiones del hogar y la comida. La cultura material del hogar encarna tanto su experiencia y trayectoria migratoria como el proceso de integración en la sociedad chilena, representando el continuo proceso de ajuste que deben enfrentar en términos culturales, sociales y materiales. Los resultados muestran que las formas de habitar y apropiarse (...) del hogar están relacionadas con los procesos de integración, pues a través de la cultura material se negocia cotidianamente la pertenencia entre dos mundos, el de origen y destino, generando la ambivalencia de estar aquí y allá simultáneamente. Sus hogares se convierten en transnacionales, donde emerge un sincretismo cultural entre ambos mundos que cohabitan: Perú se refleja en la fotografía y la comida, que permite reactualizar su pertenencia e identidad originaria, y Chile es representado por objetos tecnológicos, que materializan su trabajo sacrificado y coraje, y les permite sentirse parte de la sociedad de destino.

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

International research enrolling human subjects has raised an ethical concern regarding the just distribution of benefits between the countries that design the research and the host communities. Although several universal declarations have expressed this concern, a gap between theory and practice continues to exist, as well as a significant divergence between the design of the research protocol and the social context where it will be implemented. Although institutional review boards have made a valuable effort to evaluate international research, their sensitivity (...) to the just sharing of research benefits as well as their attention to the social context must be evaluated. This article analyzes the distribution of benefits in a review of international research in Mexico and produces an ethical reflection based on the results. (shrink)
