La necesidad de pasar de las teorías y los marcos legales idealizados a medidas prácticas y reales que se puedan vivir en la escuela, configuran una de las más significativas barreras a la hora de alcanzar la educación inclusiva; por lo anterior los escenarios prácticos como los laboratorios, son espacios que permiten la construcción de nuevas herramientas, fracturando dichas barreras excluyentes desde un enfoque centrado en las buenas prácticas. En consonancia a lo anterior la investigación plantea como objetivo reconocer las (...) comprensiones y las prácticas que han emergido desde Latinoamérica en el marco de los laboratorios didácticos para la educación.

Resumen: Este artículo tiene por finalidad indagar sobre las representaciones sociales que se tejen en torno de la educación religiosa escolar (ERE). Para ello, se empleó una investigación cualitativa amparada en una perspectiva hermenéutica y un método narrativo desarrollado a través de redes semánticas naturales y análisis de contenido. El trabajo de campo se realizó con una población de estudiantes de dos instituciones educativas de carácter privado, en la ciudad de Popayán. El análisis permitió identificar los aportes de la ERE (...) a los sujetos abordados, la descripción de sinónimos con los cuales se asocia la ERE y algunas temáticas que se deberían abordar en esta área. Estos tránsitos permitieron analizar las variaciones y tendencias que posibilitan la inferencia de su articulación con la dimensión espiritual. Abstract: The purpose of this article is to investigate the social representations that are woven around school religious education (SRE). To do this, the researchers developed a qualitative research based on a hermeneutical perspective and a narrative method developed through natural semantic networks and content analysis. The fieldwork was carried out with a population of students from two private educational institutions in the city of Popayán, Colombia. The analysis made it possible to identify the contributions of the SRE to the subjects approached, the description of synonyms with which the SRE is associated, and some issues that should be addressed in this area. These transits allowed us to analyze the variations and tendencies that make possible the inference of its articulation with the spiritual dimension. (shrink)

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)

John Dewey’s stay in Tokyo in early 1919 coincided with the height of the social movement calling for parliamentary democracy in Japan. His lectures at Tokyo Imperial University offered a new way of viewing the world and human actions that emphasizes the importance of communication and the growth of democratic personality. Those who expected to hear from him something else were disillusioned. But the disillusionment was mutual. Dewey was disillusioned by the Japanese intellectuals whose affection for European philosophy led (...) them to an uncritical acceptance of the emperor system and Japan’s imperialism abroad. His criticism toward the Japanese intellectuals grew severe as he saw the Japanese aggression while he was on the continent. Dewey’s lecture on democracy left some impact on a few of intellectuals who modified their view of person’s actions that was eventually to be crashed when Japan fell into the all-out war-making.

Deep neural networks (DNNs) have had extraordinary successes in classifying photographic images of objects and are often described as the best models of biological vision. This conclusion is largely based on three sets of findings: (1) DNNs are more accurate than any other model in classifying images taken from various datasets, (2) DNNs do the best job in predicting the pattern of human errors in classifying objects taken from various behavioral datasets, and (3) DNNs do the best job in predicting (...) brain signals in response to images taken from various brain datasets (e.g., single cell responses or fMRI data). However, these behavioral and brain datasets do not test hypotheses regarding what features are contributing to good predictions and we show that the predictions may be mediated by DNNs that share little overlap with biological vision. More problematically, we show that DNNs account for almost no results from psychological research. This contradicts the common claim that DNNs are good, let alone the best, models of human object recognition. We argue that theorists interested in developing biologically plausible models of human vision need to direct their attention to explaining psychological findings. More generally, theorists need to build models that explain the results of experiments that manipulate independent variables designed to test hypotheses rather than compete on making the best predictions. We conclude by briefly summarizing various promising modeling approaches that focus on psychological data. (shrink)

On several key issues we agree with the commentators. Perhaps most importantly, everyone seems to agree that psychology has an important role to play in building better models of human vision, and (most) everyone agrees (including us) that deep neural networks (DNNs) will play an important role in modelling human vision going forward. But there are also disagreements about what models are for, how DNN–human correspondences should be evaluated, the value of alternative modelling approaches, and impact of marketing hype in (...) the literature. In our view, these latter issues are contributing to many unjustified claims regarding DNN–human correspondences in vision and other domains of cognition. We explore all these issues in this response. (shrink)

En su desarrollo se señalan las implicaciones del constructivismo kantiano en el constructivismo político rawlsiano. Se discute cómo la conexión entre estos dos tipos de constructivismo, proporciona un procedimiento de construcción, en el que agentes racionalmente autónomos, sujetos a condiciones razonables, elaboran acuerdos sobre principios públicos de justicia para lograr un sistema justo de cooperación que trascienda generacionalmente. Se concluye, mostrando las limitaciones y (...) alcances de esta propuesta en el pensamiento filosófico y político contemporáneo. (shrink)

According to John Cassian, God bestows his supernatural grace only upon men who transcend Christian legalism and take up Christ’s consilium perfectionis. God’s grace is merited by men who strive to perfection. In so doing, they place themselves sub gratia Christi.

Resumen En este artículo reflexiono sobre la posibilidad de conceptualizar los derechos humanos como hechos institucionales, lo cual permite enmarcarlos en una perspectiva más amplia que las meramente jurídicas y morales. La propuesta se basa en la ontología social de John Searle, aunque intento replantearla desde la fenomenología de Edmund Husserl y la teoría de los actos sociales de Adolf Reinach. En la parte final introduzco problemáticas relacionadas con el papel de los Estados nacionales en la institucionalización de los (...) derechos humanos. Para ello me apoyo en la idea de Hannah Arendt de que los derechos humanos presuponen el derecho a tener derechos y la pongo en relación con observaciones más recientes de especialistas.In this paper I reflect on the possibility of conceptualizing human rights as institutional facts. This aims to frame them in a broader perspective than a merely legal or moral one. The proposal is based on John Searle’s social ontology, but I attempt to think it over with the support of Edmund Husserl’s phenomenology and Adolf Reinach’s theory of social acts. In the final part I set forward problems related with the role of national States in institutionalizing human rights. To elaborate this point, I draw on Hannah Arendt’s idea that human rights presuppose the right to have rights and relate it with more recent observations of experts. (shrink)

René Descartes (1596–1650) was born at La Haye, near Tours in France. He entered the Jesuit School at La Flèche in 1606, where he studied Latin and Greek and the classical authors, and acquired respect for the certainty of mathematics and distaste for the theories of Aristotle as developed by medieval commentators. In 1616, he took a degree in law at the University of Poitiers. There followed a period during which he travelled, for some of the time as a gentleman-officer (...) in the armies of Maurice of Nassau, Prince of Orange, and Maximilian, Duke of Bavaria. In 1625 he returned to Paris and renewed his acquaintance with Father Marin Mersenne, who was later instrumental in making his views known to many of the famous intellectuals in Europe. From 1628 to 1649 he lived in Holland and worked out in detail the scientific, philosophical and mathematical ideas that had engaged him during his travels. His main philosophical works are Rules for the Direction of the Mind, written in 1629–30 but not published until 1684, Discourse on Method, 1637, Meditations, 1641, Principles of Philosophy, 1644, and The Passions of the Soul, 1649. In 1649, Descartes accepted an invitation to visit the Queen of Sweden and instruct her in philosophy. He succumbed to the rigorous climate, and died in February 1650. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 62.1 (2001) 99-119 [Access article in PDF] Animism and Empiricism: Copernican Physics and the Origins of William Gilbert's Experimental Method John Henry In the second year of this journal's run, way back in 1941, appeared Edgar Zilsel's classic and still widely cited paper on The Origins of William Gilbert's Experimental Method. 1 Focusing on Gilbert's De magnete of 1600, undoubtedly a seminal (...) text in the history of the experimental method, 2 Zilsel argued that Gilbert borrowed his methodology from elite craftsmen, artisans, and other manual workers involved in mining, smelting, smithing, compass making, navigation, sailing, and other activities which involved working with iron or with magnets. 3 On its appearance the paper contributed to a growing and still continuing debate in the history of science about the relative importance of scholars and craftsmen in the origins of modern science. Although Zilsel's general thesis has been critically evaluated in terms of that wider debate, 4 his very specific claims about the [End Page 99] role of elite craftsmen in providing Gilbert with a ready-made experimental method, have never been properly considered. This paper attempts to reassess Zilsel's claims about the origin of Gilbert's experimental method and, in so doing, to arrive at a richer understanding of what Gilbert was trying to do in De magnete and to suggest an alternative source for his experimentalism.The first thing to note about Zilsel's argument is that it had two strands. 5 One of these pointed to actual experimental techniques used by Gilbert and showed that they can all be found in earlier writings on magnets. To be more specific, the techniques in question are to be found either in the thirteenth-century "Letter on the Magnet" written by Petrus Pergrinus or Pierre de Maricourt, first published in 1558, or in The Newe Attractive, a work on the magnetic compass written by a retired mariner, Robert Norman, first published in 1581 but reprinted three times before 1600. 6 The second strand did not involve experiments at all, with one notable exception, but simply implied or suggested that Gilbert's experimental techniques must have been inspired by miners and foundrymen, or navigators and instrument makers. The problem here, as others have objected, 7 is that it is by no means clear that elite craftsmen were engaged in performing experiments in anything like the sense of the word required for the argument to cut any ice. For Zilsel, however, "we cannot doubt that many of [the miners and foundrymen of the period], stimulated to improvements by economic competition, were wont to try new techniques and to observe natural processes." 8 A few sentences later we are told that it is "obvious" that "among such manual labourers there were experimentalists, though experimentalists with practical aims only and without theoretical knowledge." 9 [End Page 100]The philosopher of science at this point might legitimately want to suggest that an experiment is not an experiment unless it is testing a theory, but we do not have to enter into such arguable niceties. 10 We can see that there is something profoundly tendentious in Zilsel's claims simply by reading on. At this point Zilsel mentioned the only experiment specifically referred to in this strand of his argumentation. Quoting Gilbert, Zilsel showed that Gilbert himself must have descended into a mine in order, as Zilsel says, "to verify the hypothesis" that the polarity of a magnet derives from the polarity of the earth: We had a twenty pounds' heavy loadstone dug and hauled out after having first observed and marked its ends in its vein. Then we put the stone in a wooden tub on water, so that it could turn freely. Immediately the surface which had looked to the North in the mine turned itself to the North on the water. 11Zilsel did not make the absurd claim that Gilbert must have seen miners doing this kind of experiment, but he did all he could to...

In lieu of an abstract, here is a brief excerpt of the content:Spirometer, Whale, Slave:Breathing Emergencies, c. 1850John Durham Peters (bio)Breath dramatically starts with a slap at birth and ceases with death and yet we typically ignore it until it is under duress. Unlike marine mammals such as whales and dolphins who can never fully automate breathing—they sleep one brain hemisphere at a time so as to keep conscious watch, like yogis, over their respiration—we humans are mostly somnambulists with regard (...) to breath. Unlike our briny cousins, we won't drown if we neglect our breath. Our relatively accommodating habitat at the fold of lithosphere and atmosphere enables a Lethe of oblivion, though many elements of our world are hostile to breath: water, fire, earth, extremes of height, heat, or cold. Nothing could be more fundamental for aerobic terrestrial creatures than breathing. So its routine cloaking in impercipience must somehow be functional and require a great deal of nervous expenditure. (It always takes a lot of work to make an infrastructure invisible.)Breathing is a good test case for the notion, common to many variants of critical theory, that nature for humans is always second nature: what would it mean to find culture, history, and politics in something that is so relentlessly universal and given? The intensity of the urge for drink, food, sex, or sleep pales compared to that of taking a breath withheld or expelling a breath too long held. Here, it seems, desire and need converge. Breathing morphs into awareness, art and artifice when threat, absence or curiosity rouse it from its slumber—when we swim, have a coughing fit, sing, or challenge someone to a breath-holding contest. Under the earth in a mine, high in the air on a mountain or airplane, ill with a respiratory disease, or in other extreme situations, we need techniques and technologies to breathe. Like everything supposedly natural, we can't leave breathing in peace. We mold breath in techniques of speech, song, and prayer and in technologies of diving, medicine, and air travel. A full accounting of such would form a full encyclopedia of human ingenuity.1 [End Page 85]With typical flamboyance, Peter Sloterdijk declared that the atmosphere first ceased to be taken for granted, i.e., became technical, a matter of art, on 22 April 1915, with the German deployment of poison gas in World War I. On a world-historical scale, he takes this weaponization of the environment as an "air-quake" that launched modern air-conditioning in its most literal sense of climatization (as French and German has it) and not just interior cooling (Sloterdijk 89-110 passim). We need a history of comparative breathing emergencies! Every era, like every life, has its encounters with the precarity of breathing, even if not as conveniently dated or climate-change prognostic as 22 April 1915. The urban concentration of human population starting a few thousand years ago, for instance, made people co-breathers (con-spirators) in new ways and thus more prone to the contagious respiratory illnesses that have long ravaged our species.I want to look at one such moment—one marked by a deadly global respiratory illness, new instruments for producing data, worries about radical alterations to the atmosphere, comparative interest in nonhuman forms of life, and the politicization of breathing. 1850, like 2020, was a moment when breath awoke from its autonomic quiet. The nineteenth century was the great age of tuberculosis, the tragic and romantic lung disease. It was a time of fog, smoke, and mud, of climate-changing volcanic eruptions and a year without a summer, and of a mysterious, brooding "storm-cloud" that John Ruskin complained of so bitterly. Medical instruments, the whaling industry, and struggles for the abolition of slavery all brought the lungs into the foreground.SpirometerThe nineteenth century was also the great age of instrumentation. Light and sound were only the two most famous dynamic processes to yield to new graphic methods of inscription such as photography and phonography. The spirometer was one of many devices designed to render visual data of physiological functions, such as the myograph, the flame manometer, sphygmomanometer, and the kymograph. Many of them are still in use. The invention... (shrink)

Although it is frequently asserted that Greek poleis routinely laid legal claim to marine fisheries or even territorial waters, making them subject to special taxes and regulation, these assertions have little or no foundation in the evidence. For Greek fishermen the sea was freely and openly accessible, a fact that reflects the limited regulatory reach of ancient poleis. This evidence for the legal status of the sea and its fisheries is mirrored by our evidence for the status of marine fishermen, (...) conceived of as comprising distinct communities existing largely outside the legal and social structures of the polis.

1 Evidence-based policy requires researchers to provide the answers to ecological questions that are of interest to policy makers. To find out what those questions are in the UK, representatives from 28 organizations involved in policy, together with scientists from 10 academic institutions, were asked to generate a list of questions from their organizations. 2 During a 2-day workshop the initial list of 1003 questions generated from consulting at least 654 policy makers and academics was used as a basis for (...) generating a short list of 100 questions of significant policy relevance. Short-listing was decided on the basis of the preferences of the representatives from the policy-led organizations. 3 The areas covered included most major issues of environmental concern in the UK, including agriculture, marine fisheries, climate change, ecosystem function and land management. 4 The most striking outcome was the preference for general questions rather than narrow ones. The reason is that policy is driven by broad issues rather than specific ones. In contrast, scientists are frequently best equipped to answer specific questions. This means that it may be necessary to extract the underpinning specific question before researchers can proceed. 5 Synthesis and applications. Greater communication between policy makers and scientists is required in order to ensure that applied ecologists are dealing with issues in a way that can feed into policy. It is particularly important that applied ecologists emphasize the generic value of their work wherever possible. (shrink)

Are theories ‘underdetermined by the evidence’ in any way that should worry the scientific realist? I argue that no convincing reason has been given for thinking so. A crucial distinction is drawn between data equivalence and empirical equivalence. Duhem showed that it is always possible to produce a data equivalent rival to any accepted scientific theory. But there is no reason to regard such a rival as equally well empirically supported and hence no threat to realism. Two theories are empirically (...) equivalent if they share all consequences expressed in purely observational vocabulary. This is a much stronger requirement than has hitherto been recognised— two such ‘rival’ theories must in fact agree on many claims that are clearly theoretical in nature. Given this, it is unclear how much of an impact on realism a demonstration that there is always an empirically equivalent ‘rival’ to any accepted theory would have—even if such a demonstration could be produced. Certainly in the case of the version of realism that I defend—structural realism—such a demonstration would have precisely no impact: two empirically equivalent theories are, according to structural realism, cognitively indistinguishable.
