SummaryIntense, sustained nursing lengthens inter-birth intervals and is causally linked with low natural fertility. However, in traditional settings, the effects of such nursing on fertility are difficult to disentangle from those of nutrition. Results from an prospective, direct observational study of reproductive function in well-nourished Amele women who nurse intensively and persistently but who also have high fertility are here presented. Endocrine measures show that ovarian activity resumes by median 11·0 months postpartum. Median duration of postpartum amenorrhoea is 11·3 months, (...) time to next conception is 19·0 months, and the inter-birth interval is 28·0 months. Average life time fertility is 6·8. High fertility in Amele women is due both to refractoriness of reproductive function to suckling stimuli, and to maintenance of equivalent age-specific fertility rates across the reproductive life span.

Methodological norms are seen as rules defining a competitive game, and it is argued that rational recognition-seeking scientists can reach a collective agreement about which specific norms serve better their individual interests, especially if the choice is made `under a veil of ignorance', i.e. , before knowing what theory will be proposed by each scientist. Norms for theory assessment are distinguished from norms for theory choice (or inference rules), and it is argued that pursuit of recognition only affects this second (...) type of rule. An inference rule similar to `eliminative induction' is defended on the basis of such a possible agreement. According to this contractarian approach, both the explanation and the justification of scientific norms only need to refer to the preferences of individual scientists, without assuming the existence of `collective' points of view.

The decision whether to have a realist or an anti-realist attitude towards scientific hypotheses is interpreted in this paper as a choice that scientists themselves have to face in their work as scientists, rather than as a ‘philosophical’ problem. Scientists’ choices between realism and instrumentalism (or other types of anti-realism) are interpreted in this paper with the help of two different conceptual tools: a deflationary semantics grounded in the inferentialist approach to linguistic practices developed by some authors (e.g., Sellars, Brandom), (...) and an epistemic utility function that tries to represent the cognitive preferences of scientists. The first tool is applied to two different questions traditionally related to the problem of scientific realism: the non-miracle argument, and the continuity of reference. The second one is applied to the problem of unconceived alternatives, and to the distinction between realist and instrumentalist attitudes towards scientific hypotheses. (shrink)

Los científicos tratan de persuadir a sus colegas y, en última instancia, al conjunto de la sociedad, para que acepten sus tesis, descubrimientos y propuestas. Desarrollan para ello una serie de estrategias que pueden ser estudiadas como un"juego de persuasión" en el que intervienen, además de los procesos de argumentación formal e informal típicamente estudiados por la lógica y metodología de la ciencia, aspectos tradicionalmente considerados "sociológicos". En este artículo se analiza el debate sobre la ciencia del cambio climático como (...) un juego de este tipo, desde un enfoque inferencialista, sobre la base del esquema presentado en Zamora Bonilla (2006a).Scientists try to persuade their colleagues, and ultimately the whole society, of the acceptability of their claims, discoveries and proposals. In order to reach that goal, they develop a number of strategies that can be studied as a 'game of persuasion', in which, beside the processes of formal and informal argumentation typically studied by logic and methodology of science, there are also 'sociological' aspects intervening. This paper analyses the debate on climate change science as a 'persuasion game', from an inferentialist point of view, according to the lines of Zamora Bonilla (2006a). (shrink)

Using the approach known as ‘Economics of Scientific Knowledge’, this paper defends the view of scientific norms as the result of a ‘social contract’, i.e., as an equilibrium in the game of selecting the norms under which to proceed to play the game of scientific research and publication. A categorisation of the relevant types of scientific norms is offered, as well as a discussion about the incentives of the researchers in choosing some or other alternative rules.

El principio de racionalidad, o de economía, puede expresarse como la hipótesis de que los sujetos tienden a llevar a cabo aquellas acciones que maximizan la diferencia entre beneficios y costes. Este principio es ampliamente aplicado en las ciencias sociales, sobre todo, obviamente, en la teoría económica, si bien en el último medio siglo ha sido aplicado también de manera creciente a otras ramas de dichas disciplinas (sociología, ciencia política, antropología, historia, etc.). En este artículo se discute la posibilidad de (...) aplicarlo a la lingüística y la pragmática, comentando varios de los trabajos realizados desde ese punto de vista, e ilustrándolos con su aplicación al caso del uso de expresiones vagas.

The constitution of a collective judgment is analyzed from a contractarian point of view. The optimal collective judgment is defined as the one that maximizes the sum of the utility each member gets from the collective adoption of that judgment. It is argued that judgment aggregation is a different process from the aggregation of information and public deliberation. This entails that the adoption of a collective judgment should not make any rational member of the group change her individual opinion, and (...) so the collective judgment can not have any kind of epistemic superiority over the individual ones. ‡The author acknowledges Spanish Government's research projects HUM2005–01686/FISO and HUM2005-25447-E, as well as the grant PR2006-0108 which allowed a three months stay at the Helsinki Collegium for Advanced Studies, in which a big part of this paper was written. †To contact the author, please write to: Universidad Nacional de Educación a Distancia, Dpto. de Lógica, Historia y F. de la ciencia, Humanidades, Paseo de Senda del rey 7, 28040 Madrid, Spain; e-mail: [email protected].

Byung-Chul Han es uno de los intelectuales más populares del momento, habiendo basado su éxito, sobre todo, en una especie de crítica filosófica de la civilización de consumo capitalista e hipertecnificada. En este artículo se repasan algunos de los clichés habituales en su obra, para mostrar que en la mayor parte de los casos no suele haber razones para estar de acuerdo con tales críticas, sino que estas responde principalmente a un afán de esnobismo.

En su obra tardía Lukács investiga las categorías ontológicas materialistas que definen la “esencia genérica humana”. En ella arriba a la categoría de “reflejo”, un proceso cognoscitivo que incluye un movimiento recursivo entre el sujeto y el objeto, actualizado durante el trabajo, que permite al sujeto conocer el mundo objetivo e intervenir en él. El artículo plantea que, en tal movimiento, ocurre una estrategia interpretativa que corresponde con el “círculo de la interpretación” desarrollado por la tradición hermenéutica.

Este artigo discute a teoria do reflexo desenvolvida por Lenin em seu confronto com a filosofia hegeliana nos comentários que escreveu a The Science of Logic em 1915. Nesses comentários, Lenin apresenta a reflexão no contexto de uma relação reflexiva adaptativa entre o movimento da o conhecimento e o movimento da realidade; a dinâmica do conhecimento segue o movimento da realidade e a influencia. Para Lenin desses comentários, a reflexão é um momento (mental) do processo de objetificação humana que transforma (...) a realidade e origina o ser humano. (shrink)

Verisimilitude theorists (and many scientific realists) assume that science attempts to provide hypotheses with an increasing degree of closeness to the full truth; on the other hand, radical sociologists of science assert that flesh and bone scientists struggle to attain much more mundane goals (such as income, power, fame, and so on). This paper argues that both points of view can be made compatible, for (1) rational individuals only would be interested in engaging in a strong competition (such as that (...) described by radical sociologists) if they knew in advance the rules under which their outcomes are to be assessed, and (2), if these rules have to be chosen "under a veil of ignorance" (i.e., before knowing what specific theory each scientist is going to devise), then rules favoring highly verisimilar theories can be prefered by researchers to other methodological rules.

Introduction: Publications arguing against the null hypothesis significance testing (NHST) procedure and in favor of good statistical practices have increased. The most frequently mentioned alternatives to NHST are effect size statistics (ES), confidence intervals (CIs), and meta-analyses. A recent survey conducted in Spain found that academic psychologists have poor knowledge about effect size statistics, confidence intervals, and graphic displays for meta-analyses, which might lead to a misinterpretation of the results. In addition, it also found that, although the use of ES (...) is becoming generalized, the same thing is not true for CIs. Finally, academics with greater knowledge about ES statistics presented a profile closer to good statistical practice and research design. Our main purpose was to analyze the extension of these results to a different geographical area through a replication study. Method: For this purpose, we elaborated an on-line survey that included the same items as the original research, and we asked academic psychologists to indicate their level of knowledge about ES, their CIs, and meta-analyses, and how they use them. The sample consisted of 159 Italian academic psychologists (54.09% women, mean age of 47.65 years). The mean number of years in the position of professor was 12.90 (SD = 10.21). Results: As in the original research, the results showed that, although the use of effect size estimates is becoming generalized, an under-reporting of CIs for ES persists. The most frequent ES statistics mentioned were Cohen’s d and R2/η2, which can have outliers or show non-normality or violate statistical assumptions. In addition, academics showed poor knowledge about meta-analytic displays (e.g., forest plot and funnel plot) and quality checklists for studies. Finally, academics with higher-level knowledge about ES statistics seem to have a profile closer to good statistical practices. Conclusions: Changing statistical practice is not easy. This change requires statistical training programs for academics, both graduate and undergraduate. (shrink)

A diferencia de la filosofía ambiental colombiana, que alcanza un cierto grado de unidad debido a la influencia de la obra de Augusto Ángel-Maya, la filosofía ambiental argentina es más diversa en su panorama de puntos de vista y enfoques. A pesar de que no podría afirmarse que constituyen una filosofía ambiental propiamente tal, los escritos de Rodolfo Kusch podrían hacer una contribución significativa a un pensamiento ambiental anclado en las peculiaridades de nuestra cultura. Alicia Irene Bugallo ha trabajado en (...) temas de ecofilosofía, y ha introducido estos temas a jóvenes, educadores y el público en general. Alcira Bonilla ha introducido un tipo de eco-humanismo ético, que se mueve lejos del antropocentrismo a la vez que evita un fisiocentrismo o sacralización de la naturaleza. A diferencia de Bugallo y Bonilla, cuyas posiciones se acercan a la ecología profunda, María Julia Bertomeu ha enfatizado la necesidad de una clarificación normativa de reglas generalizables orientadas hacia la protección medioambiental. La Escuela Marina Vilte de la Confederación deTrabajadores de la Educación de la República Argentina ha sido un auténtico catalizador formando una nueva generación de educadores con un enfoque en temas ambientales. Un grupo de colaboración de intelectuales que trabaja en pensamiento crítico, encabezado por su coordinador Guido Galafassi, ha creado la revista Theomai y elaborado una crítica de nuestra actual situación socio-ambiental. En cuanto a nuestros medios de comunicación de masas, durante varias décadas Miguel Grinberg y Antonio Brailovsky han sido figuras inspiradoras que han difundido los temas ambientales. (shrink)

"Este trabajo explora los matices de la idea contractualista y conceptos aledaños, y examina las miradas de Hobbes, Spinoza, Montesquieu y Smith. Luego, esbozada la disputa entre Iglesia y Estado, aborda las obras más contemporáneas de Rawls, Nozick y Dworkin y las peculiaridades de "la responsabilidad de proteger", innovación teórica reciente de la teoría y la práctica políticas en la esfera internacional. Lo que hoy conocemos como "contrato social" es el producto de un largo desarrollo de la política occidental. Sus (...) orígenes están en una reelaboración de la noción romana de contrato que, en su versión política posterior moderna, reaparecerá como "contrato social". En suma, este libro versa sobre el contrato social y sus diferentes expresiones, pero no se centra exclusivamente en él. Se pretende ir más allá y ver los conceptos principales que se vinculan con la idea contractualista porque sus diferentes versiones son la clave que explica las variadas institucionalidades de las sociedades modernas. Más importante aún: en la evolución de ese arreglo institucional es posible rastrear el llamado "progreso político" de las sociedades." --Descripción del editor. (shrink)

Este artículo analiza desde una perspectiva fenomenológica-hermenéutica los aportes del pensamiento franciscano en los procesos de autoevaluación institucional de la Universidad de San Buenaventura, Bogotá. En primera instancia, se abordará el pensamiento franciscano como elemento que transversa las funciones sustantivas y todas aquellas actividades que propenden por el aseguramiento de la calidad y el mejoramiento continuo de la educación superior. En segundo lugar, se describen los significados y opiniones sobre el sistema de autoevaluación institucional en los diferentes agentes de la (...) comunidad académica Bonaventuriana en la sede Bogotá. Finalmente, se reconocerá cómo la filosofía institucional se materializa en los procesos de autoevaluación en el marco de los procesos de acreditación con el propósito de aportar elementos significativos para los planes de mejoramiento.

La memoria, la identidad, el reconocimiento, son construcciones que permiten sujetar al individuo a su pasado. Toda vez que éste es despojado de su identidad más primaria la búsqueda del ser queda reducida a la recolección de huellas para crear con ellas un relato que permita fijar al individuo en las palabras, las suyas y las del otro. Este es el objetivo del artículo, explorar estas construcciones a través de la novela Austerlitz del escritor alemán W. G Sebald, con la (...) ayuda de las propuestas hermenéuticas ricoerianas.

La poesía es un espacio en el que la palabra se materializa en instante. En ella se encuentran mundos inesperados, olvidadosque se vuelven a hacer presentes para recordar así que en la palabra de un poeta están contenidos todos los hombres, todoslos sueños, todos los tiempos. La palabra es proyección de la existencia, es una necesidad de no caer en el olvido, por lomenos en uno que no sea profundo, inolvidable, irrecuperable.

Los Ökonomisch-philosophische Manuskripte de 1844 de Marx establecen las bases del proyecto marxista de superación del capitalismo. Para ello, desarrolla una crítica al trabajo asalariado desde el concepto de alienación procedente de la dialéctica hegeliana y de la crítica de Feuerbach a la religión. Este análisis le sirve para establecer otros conceptos como los de una alteridad materialista o la reducción a la animalidad, desde los cuales sería posible construir otro marxismo alternativo al de Das Kapital.

El proyecto de emancipación que Paul Lafargue presenta en Le droit à la paresse constituye no solo uno de los primeros documentos de análisis de la sociedad capitalista y sus posibilidades revolucionarias, sino que supone, a la vez, el punto de arranque de una tradición de emancipación diferente a la del socialismo clásico. Sin embargo, en el propio desarrollo del análisis ya se vislumbran de forma teórica los problemas prácticos que dicha tradición ha acabado por desarrollar.

Revisión del libro En la cresta de la ola. Debates y definiciones en torno a la historia del tiempo presente por E. Allier Montaño, C. I. Vilchis Ortega y C. V. Ovalle (coord.).

In this article we defend the inferential view of scientific models and idealisation. Models are seen as “inferential prostheses” (instruments for surrogative reasoning) construed by means of an idealisation-concretisation process, which we essentially understand as a kind of counterfactual deformation procedure (also analysed in inferential terms). The value of scientific representation is understood in terms not only of the success of the inferential outcomes arrived at with its help, but also of the heuristic power of representation and their capacity to (...) correct and improve our models. This provides us with an argument against Sugden’s account of credible models: the likelihood or realisticness (their “credibility”) is not always a good measure of their acceptability. As opposed to “credibility” we propose the notion of “enlightening”, which is the capacity of giving us understanding in the sense of an inferential ability. (shrink)

After compulsory secondary education; many teenagers face the process of choosing a university degree. This process involves uncertainties referred to their personal abilities, interests, social expectations and professional future. The present work is aimed at determining whether the reasons behind the selection of a particular university degree differ depending on the chosen degree. Another objective is determining whether these reasons differ significantly according to gender. The sample comprises 983 students belonging to the area of social and legal sciences at the (...) University of Seville. The obtained results reveal the existence of four main reasons behind the selection of university degrees for which significant gender-related differences were observed: easy degree, job opportunities, high wages and provision of social services. Besides, these seven reasons are observed to differ widely in six of the considered degrees. (shrink)

Publishing scientific articles is a crucial activity performed by a scientist to demonstrate inclusion as part of the community of scientists: a community constituted by journal editors, reviewers, authors and readers. A manuscript submitted to journals is first read by reviewers, and their decision to accept it creates membership in the community for the author with its attendant privileges of ingroup status. Rejection bars such membership. In this article we examine the language used by this powerful individual — the journal (...) reviewer — to recognize another individual — the author — as being a member or not. Five reviewer reports of two different manuscripts submitted by non-native English-speaking authors are analyzed in this case study. Complementary discourse analytical approaches are used: group ideology, syntactic structure and personal pronouns. The analysis of the linguistic strategies used reveals three distinct positions that the reviewers adopt within this under-researched genre. (shrink)
