Research recommendations for selected IARC-classified agents.

OBJECTIVES: There are some common occupational agents and exposure circumstances where evidence of carcinogenicity is substantial but not yet conclusive for humans. The objectives are to identify research gaps and needs for twenty agents prioritized for review based on evidence of widespread human exposures and potential carcinogenicity in animals or humans. DATA SOURCES: A systematic review was conducted of new data published since the most recent pertinent IARC monograph meeting. DATA EXTRACTION: Reviewers were charged with identifying data gaps and general and specific approaches to address them, focusing on research that would be important in resolving classification uncertainties. An expert meeting brought reviewers together to discuss each agent and the identified data gaps and approaches. DATA SYNTHESIS: Several overarching issues were identified that pertained to multiple agents; these included the importance of recognizing that carcinogenic agents can act through multiple toxicity pathways and mechanisms, including epigenetic mechanisms, oxidative stress and immuno- and hormonal modulation. CONCLUSIONS: Studies in occupational populations provide important opportunities to understand the mechanisms through which exogenous agents cause cancer and intervene to prevent human exposure and/or prevent or detect cancer among those already exposed. Scientific developments are likely to increase the challenges and complexities of carcinogen testing and evaluation in the future, and epidemiologic studies will be particularly critical to inform carcinogen classification and risk assessment processes.[Authors]

The species of membracids described by C. Berg and M. Spinola classified in Sundarion Kirkaldy (Hemiptera, Cicadomorpha, Membracidae)

Pyranthe acaciae Berg, 1883 and Hemiptycha chilensis Spinola, 1852 are reinstated in Sundarion Kirkaldy, 1904 (formerly in synonymy of Callicentrus bonasia (Fabricius, 1775) (Centrotinae, Nessorhinini)). Pyranthe frustratoria Berg, 1883 (also formerly considered as synonym of Callicentrus bonasia) becomes a new synonym of Sundarion flavomarginatum (Fairmaire, 1846).

Factores involucrados en el proceso de toma de decisiones en bibliotecas de tamaño medio y pequeño. Resultados del proyecto DECIMAL.

Se presentan los resultados de la investigación realizada en el marco del proyecto europeo DECIMAL, que tiene como objetivo el desarrollo de un módulo integrado de soporte de la toma de decisiones para sistemas automatizados usados en bibliotecas pequeñas y medianas. La investigación cuantitativa y cualitativa llevada a cabo en el Reino Unido, Italia y España se ha basado en una combinación de diversos métodos: revisión de la literatura, entrevistas semiestructuradas, cuestionarios y grupos de discusión en ocasión de los dos seminarios de presentación realizados. Se distinguen dos líneas básicas de investigación: la primera en torno a la utilización real de indicadores y medidas para la gestión y evaluación de la actividad del centro, así como su interés potencial en el caso que no se hayan aplicado por el momento, y la segunda en torno al tipo de decisiones más habituales en los centros y los factores que inciden en este proceso (fuentes de información utilizadas, cultura institucional, formación, nivel de satisfacción). El artículo está centrado en los resultados obtenidos en las bibliotecas españolas, aunque se mencionan también los resultados globales a modo de comparación. Las conclusiones del estudio han dado como resultado la especificación de las necesidades de los usuarios, sobre cuya base se ha diseñado el módulo de soporte a la toma de decisiones. El proyecto ha concluido con una fase de evaluación del prototipo que ha implicado el desarrollo de cuatro versiones sucesivas del módulo con la finalidad de resolver los problemas presentados durante el proceso de evaluación.

John Dewey i l’educació democràtica = John Dewey and democratic education

In Dewey, philosophy and education are inseparable. It is often forgotten that Dewey’s conception of school and education has only been possible because he conceived thought in terms of lived experience, of constantly tested experience, of incessant research; in other words, of 'continuous search' of 'effective means of action'. In addition, according to Dewey, true education is an education in democracy, and that means investing in an education that deals with thought. The service to democratic progress is done precisely through an education in reasonability and taking into account the experience

Germination of Caesalpinia leiostachya (benth.) ducke seeds classified by size and shape

Caesalpinia leiostachya (Benth.) Ducke (Caesalpiniaceae) is a Brazilian legumenous tree whose seeds present different sizes and shapes, with dormancy imposed by a waterproof coat. In order to improve that quality of lot, seeds were classified by width in sieves of circular meshes (13, 14, 15, 16 and 17) and manually separated by shape in elongate, round and angular. Masses of 1000 seeds were determined and the thickness of each width and shape seedclass was measured, and coat permeability of the seeds classified by the width was investigated. Seeds were scarified in concentrated sulphuric acid and submitted to the germination test. Both final percentage and speed of germination index were evaluated. The classification of the seeds improved the quality of the lot, and the coat permeability was not affected by seed width. Elongated-flat seeds are of low physiological quality and should be discarded. Masses of 1000 seeds, percentage final and speed of germination increased with the width of the seeds. Both elongated and angular seeds had similar germinative behavior, and round seeds are of greater thickness and of superior physiological quality.

Opening truth to imagination : the pragmatism of John Dewey and Richard Rorty

This study explores in a comparative way the works of two American pragmatist philosophers-John Dewey and Richard Rorty. I have provided a reading of their broader works in order to offer what I hope is a successful sympathetic comparison where very few exist. Dewey is often viewed as the central hero in the classical American pragmatic tradition, while Rorty, a contemporary pragmatist, is viewed as some sort of postmodern villain. I show that the different approaches by the two philosophers-Dewey's experiential focus versus Rorty's linguistic focus-exist along a common pragmatic continuum, and that much of the critical scholarship that pits the two pragmatists against each other has actually created an unwarranted dualism between experience and language. I accomplish this task by following the critical movement by each of the pragmatists through their respective reworking of traditional absolutist truth conceptions toward a more aesthetical, imaginative position. I also show how this shift or "turning" represents an important aspect of the American philosophical tradition-its aesthetic axis. I finally indicate a role for liberal education (focusing on higher nonvocational education) in accommodating this turning, a turning that in the end is necessitated by democracy's future trajectory

Educating for love of wisdom : John Dewey and Simone Weil

The writings of John Dewey (1859-1952) and Simone Weil (1909-1943) were analyzed with a view to answering 3 main questions: What is wisdom? How is wisdom connected to experience? How does one educate for a love of wisdom? Using a dialectical method whereby Dewey (a pragmatist) was critiqued by Weil (a Christian Platonist) and vice versa, commonalities and differences were identified and clarified. For both, wisdom involved the application of thought to specific, concrete problems in order to secure a better way of life. For Weil, wisdom was centered on a love of truth that involved a certain way of applying one's attention to a concrete or theoretical problem. Weil believed that nature was subject to a divine wisdom and that a truly democratic society had supernatural roots. Dewey believed that any attempt to move beyond nature would stunt the growth of wisdom. For him, wisdom could be nourished only by natural streams-even if some ofthem were given a divine designation. For both, wisdom emerged through the discipline of work understood as intelligent activity, a coherent relationship between thinking and acting. Although Weil and Dewey differed on how they distinguished these 2 activities, they both advocated a type of education which involved practical experience and confronted concrete problems. Whereas Dewey viewed each problem optimistically with the hope of solving it, Weil saw wisdom in, contemplating insoluble contradictions. For both, educating for a love of wisdom meant cultivating a student's desire to keep thinking in line with acting-wanting to test ideas in action and striving to make sense of actions observed.

From absolutes to aesthetics : John Dewey and the art of experience /

In this thesis I sought to capture something of the integrity of John Dewey's larger vision. While recognizing this to be a difficult challenge, I needed to clear some of the debris of an overly narrow reading of Dewey's works by students of education. The tendency of reducing Dewey's larger philosophical vision down to neat theoretical snap shots in order to prop up their particular social scientific research, was in my estimation slowly damaging the larger integrity of Dewey's vast body of work. It was, in short, killing off the desire to read big works, because doing so was not necessary to satisfying the specialized interests of social scientific research. In this thesis then I made a plea for returning the Humanities to the center of higher education. It is there that students learn how to read and to think—skills required to take on someone of Dewey's stature. I set out in this thesis to do just that. I took Dewey's notion of experience as the main thread connecting all of his philosophy, and focused on two large areas of inquiry, science and its relation to philosophy, and aesthetic experience. By exploring in depth Dewey's understanding of human experience as it pertains to day-to-day living, my call was for a heightened mode of artful conduct within our living contexts. By calling on the necessity of appreciating the more qualitative dimensions of lived experience, I was hoping that students engaged in the Social Sciences might begin to bolster their research interests with more breadth and depth of reading and critical insight. I expressed this as being important to the survival and intelligent flourishing of democratic conduct.
