The molecular aspects of the microtubule system is a research area that has developed very rapidly during the past decade. Research on the assembly mechanisms and chemistry of tubulin and the molecular biology of microtubules have advanced our understanding of microtubule formation and its regulation. The emerging view of tubulin is of a macromolecule containing spatially discrete sequences that constitute functionally different domains with respect to self‐association, interactions with microtubule associated proteins (MAPs) and specific ligands. Recent studies point to the (...) role of the carboxyl‐terminal moiety of tubulin subunits in regulating its assembly into microtubules. These investigations combined with further studies on the spatial relationships between tubulin domains should provide new insights into the detailed structural basis of microtubule assembly.

This article examines the foundation myths of Brazil in the last two centuries, paying particular attention to the relationship between these myths and governmental attitudes toward the hybridity of Northern and Southern ethnic and technoscientific entities. Based upon this examination, the article argues that it is important to consider both the wider temporal frames and the shifts and sedimentations that have formed current foundation myths and shaped their relation to science and technology. Postcolonial science technology studies theories illuminate aspects of (...) this trajectory, but our analysis suggests a more complex scenario that involves internal political dynamics and the work of local intellectuals. We argue that the example of Brazilian social scientists should encourage scholars to go beyond the current focus on breaking the myths of technoscience and undertake mythmaking initiatives with wider societal resonances.

Many natural and technological systems are complex, with organizational structures that exhibit characteristic patterns but defy concise description. One effective approach to analyzing such systems is in terms of repeated topological motifs. Here, we extend the motif concept to characterize the dynamic behavior of complex systems by introducing developmental motifs, which capture patterns of system growth. As a proof of concept, we use developmental motifs to analyze the developmental cell lineage of the nematode Caenorhabditis elegans, revealing a new perspective on (...) its complex structure. We use a family of computational models to explore how biases arising from the dynamics of the developmental gene network, as well as spatial and temporal constraints acting on development, contribute to this complex organization. © 2010 Wiley Periodicals, Inc.

Nursing is possible owing to a series of intricate systemic relations. Building on an established tradition of sociological research, we critically analysed the nursing profession in Chile, with an emphasis on its education system, in the light of social systems theory. The paper's aim was to explore basic characteristics of nursing education as a system, so as to outline its current evolution. Drawing on recent developments in nursing, we applied an empirical framework to identify and discuss functionally differentiated systems that (...) are relevant to nursing and observe communications between them. We found that the dynamics of nursing as a whole develop from communications with closely related systems, including the nursing profession and the education system more broadly. While the discipline (as a system of representations) strives to control the profession (as an applied occupational field), the necessities of practicing nurses imply other forces mediating the making of the profession, a process framed by market dynamics in education and health.

La investigación ecológica a largo plazo (Long Term Ecological Research, LTER) maneja problemas que abarcan décadas o plazos más largos. El programa y su nombre formal comenzaron en Estados Unidos en 1980. Si bien los estudios y observaciones a largo plazo comenzaron tempranamente en 1400 y 1800 en Asia y Europa, respectivamente, el enfoque a largo plazo no se formalizó sino hasta el establecimiento de los programas de investigación ecológica de largo plazo en Estados Unidos. Estos programas han permitido experimentos (...) a nivel de ecosistemas y comparaciones entre sitios que condujeron a una mejor comprensión de la estructura y funcionamiento de la biosfera. El enfoque ecosistémico holístico de esta iniciativa permite también la incorporación de la dimensión humana en la ecología, y recientemente ha dado lugar al nuevo concepto de investigación socio-ecológica de largo plazo (LTSER). Hoy los programas de investigación socio-ecológica a largo plazo existen en por lo menos 32 países (esto es, los miembros de la Red Internacional de Investigación Ecológica a Largo Plazo o ILTER (International Long Term Ecological Research). Sin embargo, la consolidación de la red internacional dentro del paradigma de investigación socio-ecológica a largo plazo todavía requiere: (1) inclusión de algunas regiones remotas del mundo que aún están poco representadas, como el suroeste de América del Sur; (2) modificaciones en el tipo de investigación realizado, tales como la integración de las ciencias sociales y naturales con las humanidades y la ética, y (3) la incorporación de las conclusiones y resultados dentro de los procesos sociales y políticos. En este contexto, la naciente red de investigación socio-ecológica a largo plazo en Chile, que se extiende en el rango latitudinal más largo de bosque templado en el Hemisferio Sur, agrega una nueva región remota a las investigaciones ecológicas de largo plazo que había sido pasada por alto anteriormente. Además, la colaboración con la Universidad de North Texas y otros asociados internacionales ayuda a desarrollar un enfoque interdisciplinario para integrar las ciencias ecológicas y la filosofía ambiental, junto con los conocimientos ecológicos tradicionales, la educación informal y formal, la política, las humanidades, los procesos socio-políticos y la conservación biocultural.

This essay presents the first analysis of gender differences in productivity using panel data on scientists in low-income countries. About 540 researchers in Ghana, Kenya, and Kerala were studied using the same survey instrument in 2001 and 2005. Results indicate very few gender disparities in outcomes at either period of the study with one exception: productivity in international journals. The authors show that substantial gains in access to technology and higher education by women have not reduced the gender gap on (...) this important career dimension. (shrink)

Cet article défend l’idée que l’on peut distinguer quatre niveaux d’analyse au sein des sciences sociales (y compris l’économie) – à savoir, a) un niveau descriptif statistique, b) un niveau explicatif causal, c) un niveau explicatif téléologique, et d) un niveau téléologique prescriptif. Généralement, les sciences sociales ne considèrent que les niveaux a) et b). L’exclusion du niveau c) peut conduire à considérer comme des « anomalies » certains comportements qui ne sont pas compatibles avec des théories comme celle du (...) choix rationnel ou celle de l’utilité espérée – à savoir, des théories qui adoptent une attitude dite de « rationalité instrumentale ». Inclure le niveau c) dans la réflexion implique de considérer la « rationalité pratique » et cela rend ces anomalies « raisonnables ». L’article prend pour cadre théorique la notion de causalité et la téléologie d’Aristote. La première section introduit ces notions, tandis que la deuxième section explore les points de vue contemporains sur la causalité et la téléologie. La troisième section introduit des arguments pour établir la légitimité de l’usage des valeurs en sciences sociales. Cette étape est nécessaire, car les causes finales des explications téléologiques dans le domaine des choses humaines sont bien, en définitive, des valeurs. Ces discussions ouvrent la voie à l’introduction, dans la quatrième et dernière section, des quatre niveaux analytiques susmentionnés. Plus précisément, dans le cas de l’économie, cette discussion se fonde sur la classification des disciplines économiques chez Carl Menger. (shrink)

Emergency departments are challenging research settings, where truly informed consent can be difficult to obtain. A deeper understanding of emergency medical patients’ opinions about research is needed. We conducted a systematic review and meta-summary of quantitative and qualitative studies on which values, attitudes, or beliefs of emergent medical research participants influence research participation. We included studies of adults that investigated opinions toward emergency medicine research participation. We excluded studies focused on the association between demographics or consent document features and participation (...) and those focused on non-emergency research. In August 2011, we searched the following databases: MEDLINE, EMBASE, Google Scholar, Scirus, PsycINFO, AgeLine and Global Health. Titles, abstracts and then full manuscripts were independently evaluated by two reviewers. Disagreements were resolved by consensus and adjudicated by a third author. Studies were evaluated for bias using standardised scores. We report themes associated with participation or refusal. Our initial search produced over 1800 articles. A total of 44 articles were extracted for full-manuscript analysis, and 14 were retained based on our eligibility criteria. Among factors favouring participation, altruism and personal health benefit had the highest frequency. Mistrust of researchers, feeling like a ‘guinea pig’ and risk were leading factors favouring refusal. Many studies noted limitations of informed consent processes in emergent conditions. We conclude that highlighting the benefits to the participant and society, mitigating risk and increasing public trust may increase research participation in emergency medical research. New methods for conducting informed consent in such studies are needed. (shrink)

Em filosofia é comum o empenho em uma busca normativa, normatividade esta que aparece nos processos perceptivos quando o sujeito entra em relação com realidades de uma ordem de magnitude diferente da sua . Não acontece de outra maneira quando se trata de filosofar sobre a técnica – com efeito, em que ordem ou nível de magnitude em relação a nós ela – a técnica – se situa? Pensamos que a primeira condição para responder a tal pergunta é formulá-la em (...) termos políticos. A tese a ser desenvolvida neste trabalho, portanto, é a de que a percepção filosófica da técnica contemporânea, de um modo geral, está permeada pelo preconceito de que a técnica é algo destrutivo e que se encontra fora de controle, demandando uma filosofia moral-normativa capaz de impor-lhe os devidos limites: no entanto, não é preciso permanecer pensando assim; através da articulação entre o conceito estético-político de partilha do sensível , e os conceitos de individuação psíquica e individuação coletiva e psicopoder , pretende-se demonstrar, não a ineficácia de uma filosofia moral-normativa, mas a necessidade anterior de uma compreensão política da questão da técnica, para que, assim, tal problema possa ser recolocado de forma mais adequada em uma constelação teórica favorável à sua resolução. Tratar-se-á aqui de explicitar a relevância de uma maior sensibilização política dos sujeitos em seu processo de individuação para o caso de haver um real interesse em garantir os meios materiais de manutenção da vida no planeta.

Ubico indicios de mitos nacionales analizando obras narrativas (de Borges y algunos otros autores), y dichos acerca de Borges, centrándome en cómo se verifica, en la narrativa de Borges, (y también en sus intervenciones públicas y en lo que se dice sobre su figura) la irrupción del peronismo. Propongo un cambio de escala: sin intentar interpretar los grandes momentos constitutivos entendiéndolos como mitos de origen, intento constituir series, de características cuasi-míticas, a partir de poner en relación a breves sintagmas que (...) se reiteran en distintas unidades narrativas. Elementos transversales, que van de un relato a otro. Sintagmas que se analizan tomando al conjunto de la obra de Borges como paradigma, y no sólo relatos aislados. En primer término, exploro ciertas constantes en algunos relatos del período 1945-54. Luego me detengo en una serie de versiones contemporáneas sobre un Borges ciego a quien un joven peronista ayuda a cruzar la calle. En tercer lugar. el tema de la aparición de relatos oníricos, literariamente enunciados, sobre personas con garra de pájaro, vinculándolos a los dilemas morales de la élite intelectual en los tiempos del primer peronismo. En tanto estos conjuntos tienen mucho en común con los mitos al ser reelaboraciones sucesivas de un elemento narrativo, podrían ser abordadas con métodos de análisis míticos propios de la antropología estructural. No obstante, el material utilizado tiene diferencias con las mitologías clásicas: a) tiene versiones orales, pero también escritas; b) hechos ficcionales, pero también históricos; c) admiten un orden cronológico verificable. Por lo tanto, arriesgo aquí una exploración metodológica y teórica más bien experimental, aunque deudora de Lévi-Strauss. Concluyo que en estos dos conjuntos se verifica el funcionamiento un sistema ideológico, que es el de la formación nacional argentina, con sus tensiones y crisis. (shrink)

The main claim of this study is that, contrary to Latour’s view about the need to leave aside epistemology to deal with anything valuable about science, Mario Bunge has consistently built up a detailed and thorough epistemology. The argumentative strategy will be to show that (a) it is not true that we have never been modern (b) epistemology is here to stay, and (c) Mario Bunge endorses a strong scientific realism, a brand of materialism, systemism and emergentism, including a moral (...) dimension (there are objective values like, truth, peace and justice that deserve to be respected). Then, Bunge’s realism rejects axiological neutrality making scientists responsible for their actions. Bunge has always been modern and keeps enriching his own views. (shrink)

Cette étude défend l’idée que, contrairement à l’opinion de Latour sur la nécessité de laisser de côté l’épistémologie pour traiter de tout ce qui a de la valeur pour la science, Mario Bunge a systématiquement construit une épistémologie détaillée et approfondie. La stratégie argumentative consistera à montrer (a) qu’il est faux que nous n’avons jamais été modernes (b) que l’épistémologie est là pour de bon et (c) que Mario Bunge soutient un réalisme scientifique fort, une version du matérialisme, du systémisme (...) et de l’émergentisme, comportant une dimension morale (il existe des valeurs objectives comme la vérité, la paix et la justice qui méritent d’être étudiées). Ensuite, le réalisme de Bunge rejette la neutralité axiologique rendant les scientifiques responsables de leurs actions. Bunge a toujours été moderne et continue à enrichir ses propres positions.

The concept of beauty, and its consequent aesthetic enjoyment, has varied according the transformations of human societies over time. During the Middle Ages there were different conceptions, in both philosophy and art, of what the role of the body is in the hierarchy of aesthetic values. Our purpose is to present the aesthetic of the body that some medieval philosophers developed in their treatises (especially Isidore of Seville, Hildegard of Bingen, John of Salisbury, Bernard of Clairvaux and Thomas Aquinas), as well as some bodily representations of medieval images (illuminations and sculptures). We thus examine the issue in three ways: a) the body as a prison of the soul, b) the body as an instrument, and c) the body as degradation. (shrink)

There exist valuable methods for theorem proving in non classical logics based on translation from these logics into first-order classical logic (abbreviated henceforth FOL). The key notion in these approaches istranslation from aSource Logic (henceforth abbreviated SL) to aTarget Logic (henceforth abbreviated TL). These methods are concerned with the problem offinding a proof in TL by translating a formula in SL, but they do not address the very important problem ofpresenting proofs in SL via a backward translation. We propose a (...) framework for presenting proofs in SL based on a partial backward translation of proofs obtained in a familiar TL: Order-Sorted Predicate Logic. The proposed backward translation transfers some formulasF TL belonging to the proof in TL into formulasF SL , such that the formulasF SL either (a) belong to a corresponding deduction in SL (in the best case) or, (b) are semantically related in some precise way, to formulas in the corresponding deduction in SL (in the worst case). The formulasF TL andF SL can obviously be considered aslemmas of their respective proofs. Therefore the transfer of lemmas of TL gives at least a skeleton of the corresponding proof in SL. Since the formulas of a proof keep trace of the strategy used to obtain the proof, clearly the framework can also help in solving another fundamental and difficult problem:the transfer of strategies from classical to non classical logics. We show how to apply the proposed framework, at least to S5, S4(p), K, T, K4. Two conjectures are stated and we propose sufficient (and in general satisfactory) conditions in order to obtain formulas in the proof in SL. Two particular cases of the conjectures are proved to be theorems. Three examples are treated in full detail. The main lines of future research are given. (shrink)

This paper is an attempt to illuminate today’s economic science with the light of Aristotle’s philosophy of economics. The author first describes Aristotle’s thoughts about the economy. Then, he distinguishes and discusses three Aristotelian principles: (a) economics should be a classical practical or moral science, (b) economics should not look for an unlimited wealth, but for the wealth necessary for the good life, and (c) economics should be aimed at the common good.

La “ética del discurso” elaborada por Karl-Otto Apel representa una propuesta de “fundamentación” ética en la que se procura una “transformación” de la ética kantiana mediante dos recursos principales: el pasaje de la perspectiva monológica a la dialógica, y la superación del “rigorismo”. Se mantiene, sin embargo, en la línea kantiana, en el sentido del apriorismo universalista. La fundamentación se hace en el marco de una “reflexión pragmático-trascendental” y consiste en mostrar el “principio del discurso” o la “norma básica” como (...) condición de posibilidad de toda argumentación. Ese principio se expresa como exigencia de que todos los conflictos de intereses sean resueltos por medio de “discursos prácticos”. Lo característico —y, a la vez, el aporte original de Apel— es el reconocimiento de que un principio suficientemente fundamentado puede no ser aplicable en determinadas situaciones. Esto determina la necesidad de una “parte B” de la ética, en la que Apel indaga las condiciones de posibilidad de la aplicación. El presente trabajo concluye con el deslinde de algunas cuestiones que quedan “pendientes” en la ética de Apel, aunque también con la aclaración de que en el balance general pesan más los aportes que los problemas pendientes.

Two paradigms have guided emotion research over the past decades. The dual-system view embraces the long-held Western belief, espoused most prominently by decision-making and social cognition researchers, that emotion and reason are often at odds. The integrative view, which asserts that emotion and cognition work synergistically, has been less explored experimentally. However, the integrative view (a) may help explain several findings that are not easily accounted for by the dual-system approach, and (b) is better supported by a growing body of (...) evidence from human neuroanatomy that has often been overlooked by experimental neuroscience.

This report analyses the aplicability of the principles of consciousness developed in the ASys project to three of the most relevant cognitive architectures. This is done in relation to their aplicability to build integrated control systems and studying their support for general mechanisms of real-time consciousness. To analyse these architectures the ASys Framework is employed. This is a conceptual framework based on an extension for cognitive autonomous systems of the General Systems Theory (GST). A general qualitative evaluation criteria for cognitive (...) architectures is established based upon: a) requirements for a cognitive architecture, b) the theoretical framework based on the GST and c) core design principles for integrated cognitive conscious control systems.

In this paper I explore whether three different approaches to connexivity – namely, Lewis and Langford’s, Wansing’s and Egré and Politzer’s – can be non-trivially related. Lewis and Langford’s approach consists of the definition of the conditional in terms of consistency via the definition of possibility in terms of consistency and Lewis’ definition of the (strict) conditional in terms of possibility; Wansing’s approach is based on his definition of the falsity condition for the conditional as “if A is true then (...) B is false”; Egré and Politzer’s approach relies on the modalization of the falsity condition for the conditional in its conditional form (A→◇~B). With this background in mind, I build upon Estrada-González’s work relating connexivism and possibilism, the thesis according to which everything is possible. Estrada-González’s work relates Lewis and Langford’s connexive approach with Nelson’s idea that every proposition is self-consistent. He does so using a fragment of LP augmented with a special conditional. This relation has resulted in the study and postulation of several truth-functional modalities, some of which have already been discussed elsewhere. I employ several truth-functional modalities to evaluate Egré and Politzer’s falsity conditions for the conditional. I show that in using Béziau’s truth-functional modality ◇B, definable in Estrada-González’s framework, one can retain in a single framework the three different approaches. More specifically, distinguishing the notion of logical equivalence from the notion of interderivability and these two from the notion of coimplication, it is possible to relate ~(A→B) and (A→◇~B) as interderivable schemas and in a valid biconditional. I also show some consequences of this for Béziau’s negative appraisal of three-valued truthfunctional modalities. (shrink)

Resumen: En muchas lenguas las cláusulas adverbiales iniciales presentan una repetición del predicado de la oración anterior, lo que se conoce como enlace tail-head. Este trabajo busca describir las construcciones de eth del quichua santiagueño de acuerdo con dos parámetros: a) el grado de solapamiento semántico entre los predicados de la construcción de eth, y b) el grado de integración eventiva de la adverbial inicial con la cláusula principal. El primer parámetro permite identificar construcciones verbatim -con repetición exacta del verbo (...) anterior- y no verbatim -sin repetición exacta-. El segundo parámetro se manifiesta en la forma que adopta la cláusula “cabeza”. Así, se identificaron, por un lado, una forma converbal y, por el otro, cláusulas con los sufijos del sistema de conmutación de la referencia. La interacción entre estos dos parámetros muestra que las diferentes construcciones de eth poseen diversas funciones discursivas, en particular para la coherencia temática.: In many languages preposed adverbial clauses repeat the previous verb or predicate, which phenomenon has been termed tail-head linkage. This paper aims to describe THL constructions in Santiagueño Quichua according to two parameters: a) the degree of semantic overlap between the predicates of the THL constructions, and b) the degree of event integration of the preposed adverbial with its main clause. The first parameter allows the identification of verbatim constructions -with exact repetition of the previous predicate- and non verbatim constructions -without exact repetition-. The second parameter manifests itself in the form the head clause might adopt, where it is a converb or it takes switch reference suffixes. The interplay of both parameters shows that the different THL constructions possess diverse discourse functions, particularly regarding thematic coherence. (shrink)

This book is a rare piece of writing in any language. Its first merit is that it puts in 360-odd pages a concise and highly readable history of economic thought from Ricardo and Adam Smith to modern times as seen through the critical spectacles of classical Marxist political economy. Its second merit is that it does not dismiss capitalist economics as mere apologetics or mystification, but--in the genuine spirit of Marx's principles of criticism--it also seeks out the positive aspects (...) of methodology and understanding which can help clarify the workings and malfunctions of late twentieth century capitalism. Nor does the author bow before any mystic infallibility of current Soviet economic theory. Among the most interesting treatments are those of the theories of Böhm-Bawerk, Schumpeter, Marshall, Veblen, Hobson, Hilferding, Kalecki, Keynes, Harrod-Domar, Kaldor, Sraffa, Galbraith, Myrdal, Strachey, and Bettelheim. Aguilar is a professor of economics at the University of Mexico and displays impressive scholarship and perception in his chosen field. His call is for Latin American intellectuals to free themselves from the restrictions of the economic theories of capitalist economics and to dedicate themselves to the development of the theoretical foundations necessary for the liberation of Latin America not only from economic domination, but also from the cultural, social, and political tutelage of their economic masters. Marx's model of capitalism and Lenin's model of imperialism have not lost their power in Latin America as grounds for explaining the continued economic, cultural, social, and political backwardness of this huge area. The present work demonstrates the intellectual sweep of this power. The book is well-footnoted, but, deplorably, lacks an index.--H. B. (shrink)

To Aaron Pacitti and Michael Cauvel–whose journal article, “Rent-Seeking Behavior and Economic Justice: A Classroom Exercise” broadly argues that “understanding the [complexities] of rent-seeking behavior helps fill the gap between economics and politics”–the varieties of rent are wide and, therefore, can only be described in their category-specific positions. I will discuss three of these categories in more detail below, but for now, I propose that a useful working grasp of economic rent involves “the amount paid to the owner of a (...) factor of production over the cost that is to be necessarily incurred on utilizing such elements in the production process.” In math terms, ‘economic rent’ equals the agreed-upon-amount paid by the consumer (when that amount far exceeds the market value of the product) minus the cost spent by the producer to make the product (when that cost is far below the typical amount to produce the product). Originally, the concept of economic rent concerned land ownership and the production of natural goods. Two major economists, Adam Smith and David Ricardo, offered insights into the general makeup and logic of what they called, the rent of land and simply rent, respectively. (shrink)

En este trabajo ofrezco un análisis de algunas de las ideas más importantes sostenidas por Ricardo Caracciolo en su ensayo sobre hechos y justifi cación de las decisiones judiciales. Estas tesis son: a) tesis de la aplicación posible. Las normas generales sólo se pueden aplicar a los casos que ellas regulan; b) tesis de la aplicación efectiva. Una norma general es aplicada a un hecho sólo si la premisa que describe ese hecho es verdadera. Este artículo muestra que hay (...) buenas razones para revisar ambas tesis ya que ellas pasan por alto una distinción relevante entre distintos sentidos de ‘casos individual’: casos individuales de un universo del discurso y casos individuales de un caso genérico. Como consecuencia de ello, se señala que es necesario modelar un concepto de justifi cación jurídica que no presuponga a esas mencionadas tesis. (shrink)

Beginning with a survey of the shortcoming of theories of organology/media-as-externalization of mind/body—a philosophical-anthropological tradition that stretches from Plato through Ernst Kapp and finds its contemporary proponent in Bernard Stiegler—I propose that the phenomenological treatment of media as an outpouching and extension of mind qua intentionality is not sufficient to counter the ̳black-box‘ mystification of today‘s deep learning‘s algorithms. Focusing on a close study of Simondon‘s On the Existence of Technical Objectsand Individuation, I argue that the process-philosophical work of Gilbert (...) Simondon, with its critique of Norbert Wiener‘s first-order cybernetics, offers a precursor to the conception of second-order cybernetics (as endorsed byFrancisco Varela, Humberto Maturana, and Ricardo B. Uribe) and, specifically, its autopoietic treatment of information. It has been argued by those such as Frank Pasquale that neuro-inferential deep learning systems premised on predictive patterning, suchas AlphaGo Zero, have a veiled logic and, thus, are ̳black boxes‘. In detailing a philosophical-historical approach to demystify predictive patterning/processing and the logic of such deep learning algorithms, this paper attempts to shine a light on such systems and their inner workingsàla Simondon.
