Do cultural models facilitate particular ways of perceiving interactions in nature? We explore variability in folkecological principles of reasoning about interspecies interactions. In two studies, Indigenous Panamanian Ngöbe and U.S. participants interpreted an illustrated, wordless nonfiction book about the hunting relationship between a coyote and badger. Across both studies, the majority of Ngöbe interpreted the hunting relationship as cooperative and the majority of U.S. participants as competitive. Study 2 showed that this pattern may reflect different beliefs about, and perhaps different (...) awareness of, plausible interspecies interactions. Further probes suggest that these models of ecological interaction correlate with recognition of social agency in nonhuman animals. We interpret our results in terms of cultural models of nature and nonhuman agency. (shrink)

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.

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)

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)

Escribir hoy en día un libro sobre hermenéutica, que tal hermenéutica se refiera a la desarrollada por G. Gadamer en su conocido Verdad y método y que se pretenda añadir algo nuevo a lo mucho escrito sobre el tema parecería, a primera vista, empresa irrealizable. Que ambas pretensiones inspiren la sólida monografía de María G. Navarro —titulada Interpretar y argumentar— constituye empresa audaz y arriesgada, plena de coraje innovador, que provoca admiración, curiosidad e interés. Contra lo que pudiera parecer a (...) primera vista, el libro contiene un alto componente de originalidad y creatividad, debido a la estratagema metodoló-gica de que se sirve la autora. A saber, una hermenéutica in obliquo, estrategia consistente en interpretar a la hermenéutica gadameriana a través del prisma de la lógica de la argumentación. (shrink)

Wittgenstein’s “grammatical method” analyzes multiple uses of language across contexts of use, with the aim of identifying differences and dissolving conceptual confusion. This paper uses Wittgenstein’s method to undermine Jorge L. A. Garcia’s volitional account of racism. Garcia claims that his theory accommodates the ordinary use of terms like “racist belief.” However, he did not consider whether such terms might have multiple uses/meanings. My paper identifies three uses of “racist belief” that escape Garcia’s analysis. Consequently, philosophers should (...) take Wittgenstein’s advice to heart: do not assume that target-terms have a single use, but “look and see” whether they do. (shrink)

J. L. A. Garcia holds that my defense of voluntary euthanasia in an earlier paper amounts to an "assault on traditional common sense" about what medical ethics permits physicians to do, particularly insofar as I hold that a physician's duty to abstain from intentionally killing is only a defeasible duty, not an unconditional one. But I argue here that it is Garcia's views that are more at odds with common sense, and that voluntary euthanasia is in fact a (...) humane alternative that respects patient autonomy and is consistent with the most fundamental moral duties of physicians. Among these is a duty to relieve suffering, which can sometimes outweigh the fundamental duty to conserve life. (shrink)

The fitting attitude analysis of value states that for objects to have value is for them to be the fitting targets of attitudes. Good objects are the fitting targets of positive attitudes, while bad objects are the fitting targets of negative attitudes. The following paper presents an argument to the effect that value and the fittingness of attitudes differ in terms of their explanations. Whereas the fittingness of attitudes is explained, inter alia, by both the properties of attitudes and those (...) of their fitting targets, the explanation of value tends to have a different content. In particular, objects have value in virtue of the features that make them valuable, and these need not involve any attitudinal properties. If this is right, then there are reasons to doubt the claim that for objects to have value is just for them to be the fitting targets of attitudes. Insofar as value is a property, it appears to be distinct from the property of objects being the fitting targets of attitudes. (shrink)

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.

The explanatory objection against the fitting attitude account of value states that if the properties of attitudes explain fittingness facts, but do not always explain value facts, then value facts cannot be identical with or reduced to fittingness facts. One reply to this objection is to claim that the constitutive properties of attitudes also explain value facts, for they are enablers for the value possessed by an object. In this paper we argue that the enabling maneuver exposes FA to a (...) new explanatory objection, to the extent that the explanatory role played by the constitutive properties of attitudes in value facts is assumed to be different from the explanatory role they play in fittingness facts.

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)

Final value accrues to objects that are good for their own sakes, while instrumental value accrues to objects that are good for the sake of their effects. The following paper aims to show that this distinction cuts across some surprising areas of the evaluative domain. This means that there may be some unexpected types of value that can come in a final or instrumental form. The argument proceeds by looking at two prominent types of value, namely kind-value and personal value. (...) The former accrues to objects that are good as the kinds of things that they are, while the latter accrues to objects that are good for someone. Substantive examples are offered in support of the idea that these types of value can come in final or instrumental form. The substantive examples are then given additional support by considering the structure and behavior of fitting attitudes. (shrink)

Philosophers have applied the framework of constitutive grounds to make sense of the disagreement between subjectivism and objectivism. The framework understands the two theories as being involved in a disagreement about the extent to which value is determined by attitudes. Although the framework affords us with some useful observations about how this should be interpreted, the question how value can be determined by attitudes in the first place is left largely unanswered. Here we explore the benefits of a positive interpretation (...) which aims to address this oversight and make the framework more informative. This interpretation, which is inspired by the recent work of Schroeder and Sobel, claims that the relevant sense in which value can be determined by attitudes is discovered by seeing how facts can be endowed with the normative property of being a reason. We argue that this interpretation significantly deepens our understanding of the disagreement between subjectivism and objectivism. (shrink)

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)

This work presents a novel approach to forecast streaming big time series based on nearest similar patterns. This approach combines a clustering algorithm with a classifier and the nearest neighbours algorithm. It presents two separate stages: offline and online. The offline phase is for training and finding the best models for clustering, classification and the nearest neighbours algorithm. The online phase is to predict big time series in real time. In the offline phase, data are divided into clusters and a (...) forecasting model based on the nearest neighbours is trained for each cluster. In addition, a classifier is trained using the cluster assignments previously generated by the clustering algorithm. In the online phase, the classifier predicts the cluster label of an instance, and the proper nearest neighbours model according to the predicted cluster label is applied to obtain the final prediction using the similar patterns. The algorithm is able to be updated incrementally for online learning from data streams. Results are reported using electricity consumption with a granularity of |$10$| minutes for 4-hour-ahead forecasting and compared with well-known online benchmark learners, showing a remarkable improvement in prediction accuracy.

The first European settlements in the new world faced technical issues with the help of the XVI century scientific advances. Besides briefly exposing the scientific and technological situation, this paper explores, with the help of reverse engineering, two singular mechanical wits representative of the technological advances introduced in America to overcome different problems. Firstly, a pump, based on an alternative movement system through crankshafts and pistons used against the continuous flooding suffered in the Ciudad de México valley. Although flooding remained (...) a problem (it was solved in the XX century), hydraulic pumps were essential for continuous soil drainage. Secondly, a port crane for handling cannons, military devices, and construction materials during the Lima fortification in the XVII century. For both cases, reverse engineering, through engineering methods, Computer-Aided Design CAD programs, and additive manufacturing, provides virtual and/or tangible mockups that help to analyze and improve our knowledge about the dimensions, materials, and functions of used (and currently lost) mechanical systems during the American colonization.

In this paper art history and visual studies, the disciplines that study visual culture, are presented as a field whose conjectural paradigm can be used to understand the epistemic problems associated with abduction. In order to do so, significant statements, concepts and arguments from the work of several specialists in this field have been highlighted. Their analysis shows the fruitfulness and potential for understanding the study of visual culture as a field that is interwoven with the assumptions of abductive cognition.

Abstract“The Book of Secrets in the Results of Ideas”, usually called “The Book of Secrets” is a codex containing drawings and descriptions of thirty-one artifacts attributed to the engineer Alī Ibn Khalaf al-Murādī, who lived in Andalusia in southern Spain at the beginning of the 11th century. This manuscript is one of the first written testimonies that describe medieval mechanisms with complex precision. The aim of this work is to reconstruct and study from a historical and technological point of view (...) two of the ancient artifacts contained in the “Book of Secrets”, the “Fortress Demolisher” and the “Magic Well”. The “Fortress Demolisher” is a war machine designed to demolish the upper part of the walls or towers and consists of a battering ram mounted on a platform that can be raised several meters above the ground using a scissor mechanism. The “Magic Well” is a mechanism with several pulleys whose purpose is to raise water several meters from the bottom of a well by collecting a small portion of rope. To reconstruct the two artifacts, a digital model and a detailed study of the geometry and operation of the mechanisms, were first carried out. 3D printing, using the Fused Deposition Modelling technology, made the physical reproduction. The digitization and physical reproduction by 3D printing of the mechanisms represent an update of the traditional ways of transmitting knowledge. The use of these new technologies makes the knowledge more accessible, understandable and attractive. (shrink)

Analizar epistemológicamente los problemas de salud requiere incorporar la epistemología a los programas de posgrado en ciencias de la salud. Con el propósito de caracterizar los campos problemáticos que fundamenten el diseño de un programa académico para el curso de epistemología en ciencias de la salud se realizó un estudio con el enfoque de la hermenéutica gadameriana en tres etapas. El punto de partida expone la concepción de hombre, conocimiento y epistemología. El horizonte de comprensión se elaboró con tendencias epistemológicas (...) hegemónicas. La fusión de horizontes integró las características de los siguientes campos problemáticos: epistemología de las ciencias de la salud, lógica de las ciencias de la salud, tendencias epistemológicas en ciencias de la salud, problemas epistemológicos de las ciencias de la salud. Se concluye que los campos problemáticos descritos introducen al estudiante a la reflexión de su práctica científica mediante el análisis racional, axiológico y crítico. Analyzing health problems from an epistemological point of view requires epistemology to be included on health sciences postgraduate courses programs. Aimed at characterizing the problematic fields used as basis for the design of a health sciences epistemology academic program, a study with an approach to Gadamer hermeneutics in three stages was carried out. The starting point shows man, knowledge and epistemology conceptions. The comprehension horizon was made with epistemological-dominant trends. The horizons merge included characteristics from the following problematic fields: health sciences epistemology, health sciences logic, epistemological trends in health sciences, health sciences epistemological problems. It was reached the conclusion that the described problematic fields introduce students to their scientific practice reflection through a rational, axiological and critical analysis. (shrink)

Background conditions are thought to explain how objects can have value in virtue of certain features and how reasons can consist in certain facts. The following paper provides an account of what background conditions are and what effect they have on normative features. It defends the idea that if values depend on reasons, then there is nothing really surprising or mysterious about the presence of background conditions in normative explanations. Background conditions turn out to be a natural and predictable result (...) of normative hierarchies that treat reasons as metaphysically fundamental relative to other normative features. The account is also shown to have advantages over competing accounts in that it is able to capture the functional criteria that characterize background conditions while remaining theoretically parsimonious.

The idea that natural selection acts on many levels—and not only at the level of organisms or individual genes—is increasingly accepted among biologists. However, it is not easy to reconcile this idea with the strictly “individualistic” conception of the evolutionary process that has always characterized Darwinian thought. Moreover, the individuality of some forms of life is a vague concept and therefore controversial. This is the case of Candidatus Magnetoglobus multicellularis, whose discovery immediately inspired the following question: Does the concept of (...) individuality have degrees? Alternatively, how far is this structure of prokaryotic cells from deserving to be called an organism? In this article, we propose a new conceptual scheme based on an idea of individuality that is not limited to organisms and that makes sense in terms of Darwinian evolution. In this conceptual scheme, selection at levels above that of the individual organism is interpreted as the evolutionary emergence of higher-level individuality. This proposal may serve as a basis on which to construct a promising hierarchical evolutionary theory. (shrink)
