Addressing conflicts of interest in the research paper: a societal demand in contemporary science?

In the last decade, dialogue between science and society has found a forum in an increasing number of publications on topics such as public engagement with science and public trust in science. Concerning the latter, issues that include cases of research misconduct, accountability in research, and conflicts of interest (COIs) have shaped global discussions on the communication of science. In the publication setting, the perception that hiding COIs and/or not managing them well may affect public trust in the research record has grown among editors. We conducted a search for editorials addressing COIs between 1989 and 2011, using four major databases: Medline/PubMed, Embase, Scopus, and Web of Knowledge. We explored the content of these editorials and the relationship they established between COIs and the public trust in science. Our results demonstrate that the relationship between disclosure of COIs and public trust in science has become a major concern among editors. We, thus, argue that COIs should be discussed more openly and frequently in graduate courses in the sciences, around the globe, not only in biomedical but also in non-biomedical areas. This is a critical issue in contemporary science, as graduate students are the future voices and decision-makers of the research community. Therefore, COIs, especially in the broader context of science and society, merit closer attention from policymakers, researchers, and educators. At times of great expectations for public engagement with science, mishandling of COIs may have undesirable consequences for public engagement with science and confidence in the scientific endeavor.

Citizens and Contemporary Science Ways to dialogue in science centre contexts.

The current paper presents a study conducted at At-Bristol Science Centre, UK. It is a front-end evaluation for the “Live Science Zone” at At-Bristol, which will be built during the autumn of 2004. It will provide a facility for programmed events and shows, non-programmed investigative activities and the choice of passive or active exploration of current scientific topics. The main aim of the study is to determine characteristics of what kind of techniques to use in the Live Science Zone. The objectives are to explore what has already been done at At-Bristol, and what has been done at other science centres, and to identify successful devices. The secondary aim is mapping what sorts of topics that visitors are actually interested in debating. The methods used in the study are deep qualitative interviews with professionals working within the field of science communication in Europe and North America, and questionnaires answered by visitors to At-Bristol. The results show that there are some gaps between the intentions of the professionals and the opinions of the visitors, in terms of opportunities and willingness for dialogue in science centre activities. The most popular issue was Future and the most popular device was Film.

Becoming Other: Virtual Realities in Contemporary Science Fiction

The purpose of this thesis was to explore the boundary between human and other created by virtual worlds in contemporary science fiction novels. After a close reading of the three novels: Surface Detail, Existence, and Lady of Mazes, and the application of contemporary literary theories, the boundary presented itself and led to the discovery of where the human becomes other. The human becomes other when it becomes lost to the virtual world and no longer exists or interacts with material reality. Each of the primary texts exhibits both virtual reality and humanity in different ways, and each is explored to find where humanity falls apart. Overall, when these theories are applied to real life there is no real way to avoid the potential for fully immersive virtual worlds, but there are ways to avoid their alienating effects.

Organização parlamentar, processo decisório e produção legislativa no cenário político capixaba : uma análise da Assembléia do Estado do Espírito Santo na 16ª legislatura (2007-2010)

Esta pesquisa é um estudo sobre o processo legislativo e a produção de leis na ALES, durante a 16ª Legislatura. O escopo do estudo foi o de analisar o impacto das regras, contidas no regimento interno e na Constituição estadual, na produção de leis entre 2007 e 2010. O pressuposto geral da abordagem advém do Novo Intitucionalismo como movimento teórico da Ciência Política contemporânea, que nos permite inferir que as regras institucionais, para além de serem simples regras de organização das Casas Legislativas, influenciam no processo decisório e, consequentemente, na produção de leis. Importando as análises dos modelos distributivo, informacional e partidário de organização dos Legislativos, a pesquisa permitiu concluir que, a ALES, de 2007 a 2010, manteve seus trabalhos alinhados à versão distributiva. O parlamentar capixaba atuou, individualmente, a fim de manter suas bases eleitorais. Com relação à atuação do sistema comissional, foi identificada a inaptidão das comissões da ALES para influenciar o processo decisório. As comissões permanentes não possuem capacidade de moldar os projetos que por elas tramitam. O regime de tramitação influencia diretamente a produção de leis da ALES, notadamente, nas leis de autoria do Executivo, já que estas, tramitaram, quase que na totalidade, em regime de urgência. No que tange aos partidos, a fragmentação partidária identificada na ALES acaba por refletir nos dados obtidos sobre a produção de leis, na medida em que não existe uma verdadeira articulação em torno dos partidos como atores determinantes no processo legislativo da ALES. Enfim, em apertada síntese, foi possível constatar a imposição da agenda de trabalhos pelo Executivo. Os projetos aprovados, de temas importantes e abrangência estadual, foram, em sua maioria, propostos pelo Executivo; a urgência impacta frontalmente os projetos do Executivo, que são aprovadas em pequeno espaço de tempo; as comissões não possuem poder mínimo de influência nos projetos de autoria do Executivo; e os partidos, altamente fragmentados, não constituem instância com capacidade de articulação.

Unorthodox Humeanism

The thesis is situated in the domain of contemporary metaphysics of science. The question is which ontology fits best with our knowledge of the world. The method chosen is the one of evaluating the consequences of different ontological frameworks against the background of our scientific knowledge of the world. The thesis analyses the two main frameworks in today's metaphysics of science, Humeanism and dispositionalism. It advocates that only an unorthodox version of Humeanism and only an unorthodox version of dispositionalism can be defended, the unorthodox character of these versions consisting in taking the fundamental properties to be relations rather than intrinsic properties. The thesis then sets out in detail what such an unorthodox version of Humeanism amounts to. Chapters 1 and 2 introduce the standard versions of Humeanism and dispositionalism, focussing on the accounts of laws of nature and causation. Chapter 3 compares both these positions and concludes that as far as the orthodox versions are concerned, dispositionalism fares better than Humeanism, since it can avoid Humeanism's commitments to quidditism and humility. However, as is argued in chapter 4, instead of replying to the objections from quidditism and humility by switching to dispositionalism, there is an unorthodox version of Humeanism available that does not run into these problematic consequences and that is supported by science: if one takes the fundamental physical properties to be relations instead of intrinsic properties, the objection from quidditism is avoided, since there is no hidden intrinsic essence of relations. As regards the objection from humility, one can maintain that science is in principle able to provide knowledge of the fundamental relations that there are in the world so that there is no principled ignorance. Consequently, the thesis concludes that Humeanism and dispositionalism are on a par as regards the remaining charge of humility. Unorthodox Humeanism provides a competitive and adequate ontology in the light of contemporary science.

La fraternidad de los cuerpos posthumanos. La ciencia ficción como territorio de reproducción y de resistencia del imaginario masculino tradicional

This paper analyses the representations of the body present in contemporary science-fiction literature and film. Using theoretical concepts by Althusser, Foucault and Haraway, the text establishes first a typology of cybernetic organisms in contemporary culture and reviews its presence and ideological implications in films like Robocop (1987), Johny Mnemonic (1995) or Matrix (1999). The paper argues for a self-conscience as political and historical subjects in order to avoid falling into a fallacious cyberandroginy that reinforces phallogocentric power structures.

The neural processes generating visual phenomenal consciousness: ERP and neuronavigated brain stimulation studies

One of the greatest conundrums to the contemporary science is the relation between consciousness and brain activity, and one of the specifi c questions is how neural activity can generate vivid subjective experiences. Studies focusing on visual consciousness have become essential in solving the empirical questions of consciousness. Th e main aim of this thesis is to clarify the relation between visual consciousness and the neural and electrophysiological processes of the brain. By applying electroencephalography and functional magnetic resonance image-guided transcranial magnetic stimulation (TMS), we investigated the links between conscious perception and attention, the temporal evolution of visual consciousness during stimulus processing, the causal roles of primary visual cortex (V1), visual area 2 (V2) and lateral occipital cortex (LO) in the generation of visual consciousness and also the methodological issues concerning the accuracy of targeting TMS to V1. Th e results showed that the fi rst eff ects of visual consciousness on electrophysiological responses (about 140 ms aft er the stimulus-onset) appeared earlier than the eff ects of selective attention, and also in the unattended condition, suggesting that visual consciousness and selective attention are two independent phenomena which have distinct underlying neural mechanisms. In addition, while it is well known that V1 is necessary for visual awareness, the results of the present thesis suggest that also the abutting visual area V2 is a prerequisite for conscious perception. In our studies, the activation in V2 was necessary for the conscious perception of change in contrast for a shorter period of time than in the case of more detailed conscious perception. We also found that TMS in LO suppressed the conscious perception of object shape when TMS was delivered in two distinct time windows, the latter corresponding with the timing of the ERPs related to the conscious perception of coherent object shape. Th e result supports the view that LO is crucial in conscious perception of object coherency and is likely to be directly involved in the generation of visual consciousness. Furthermore, we found that visual sensations, or phosphenes, elicited by the TMS of V1 were brighter than identically induced phosphenes arising from V2. Th ese fi ndings demonstrate that V1 contributes more to the generation of the sensation of brightness than does V2. Th e results also suggest that top-down activation from V2 to V1 is probably associated with phosphene generation. The results of the methodological study imply that when a commonly used landmark (2 cm above the inion) is used in targeting TMS to V1, the TMS-induced electric fi eld is likely to be highest in dorsal V2. When V1 was targeted according to the individual retinotopic data, the electric fi eld was highest in V1 only in half of the participants. Th is result suggests that if the objective is to study the role of V1 with TMS methodology, at least functional maps of V1 and V2 should be applied with computational model of the TMS-induced electric fi eld in V1 and V2. Finally, the results of this thesis imply that diff erent features of attention contribute diff erently to visual consciousness, and thus, the theoretical model which is built up of the relationship between visual consciousness and attention should acknowledge these diff erences. Future studies should also explore the possibility that visual consciousness consists of several processing stages, each of which have their distinct underlying neural mechanisms.

Inuit ethnobotany and ethnoecology in Nunavik and Nunatsiavut, northeastern Canada

Les habitats uniques de l'écotone forêt boréale-subarctique dans le nord du Canada subissent les contrecoups du changement climatique. Combinés aux effets de la mondialisation, les changements environnementaux touchent les Inuits de cette région et imposent des contraintes importantes sur leur mode de vie traditionnel, ce qui a des répercussions sur leur langue et les savoirs qui l'accompagnent. Cette étude compare deux aspects de l’ethnobiologie inuite : a) les noms et les utilisations des plantes par les Inuits de Nain, Nunatsiavut, suivis par une comparaison des utilisations avec la communauté inuite de Kangiqsualujjuaq, Nunavik, et b) une analyse des types de lieux ou d’habitats que les Inuits reconnaissent et nomment. Des interviews semi-dirigés ont été menés à Nain, Nunatsiavut et à Kangiqsualujjuaq, au Nunavik. Les plantes mentionnées sont utilisées comme aliment, thé, médecine, combustible, construction, nettoyage, et autres utilisations. Les deux communautés ont utilisé un nombre égal de plantes, avec des proportions équivalentes de taxons vasculaires/invasculaires, de formes de croissance (habitus), et d’espèces par catégorie d'utilisation. Les éléments du paysage les plus fréquemment rapportés sont d’ordre topographique, hydrologique ou écologique. L’intégration des concepts inuits, quant aux plantes et au paysage, à ceux de la science occidentale peut améliorer notre compréhension de l'écologie subarctique, aider à impliquer les acteurs locaux dans les décisions sur le développement de leur territoire et, conséquemment, modifier l'aménagement du territoire ainsi que les initiatives de conservation de la biodiversité. Ces concepts ont également des répercussions sur les stratégies d'adaptation face aux changements climatiques.

Possíveis implicações epistemológicas do conceito de interação não-ordinária para a noção de sincronicidade de Jung

Este estudo teórico visa propor, em sentido mais amplo, a noção de totalidade não-fragmentada como referencial de "visão do mundo" e, consequentemente, de construção do conhecimento. Para tanto, faz-se necessário estabelecer as perspectivas de um redimensionamento epistemológico, objetivando edificar os fundamentos para a viabilização de uma teoria sistêmica do conhecimento, baseada na noção de totalidade. Tal teoria se reporta, em âmbito mais estrito, aos chamados sistemas autogênicos não-ordinários, que são sistemas especiais, voltados a se constituir como uma alternativa de interpretação para os sistemas humanos. Nesse sentido, tem-se por objetivo orientar-se para a síntese de uma conceituação especial para o domínio do "vivo", em detrimento da vigência de uma linguagem ainda "fisicalista", oriunda da transferência de conceitos da ciência física para as outras áreas do conhecimento. Pretende-se, assim, que a conceituação dos chamados "sistemas autogênicos não-ordinários" se constitua como passível de ser aplicada ao âmbito da psicologia e, mais especificamente, aos fenômenos da psique. Para se alcançar esta meta, procurar-se-á exemplificar a procedente utilidade dos sistemas autogênicos à psicologia através de tentativa, ainda incipiente, de aplicabilidade da noção de interação não-ordinária (foco central desses sistemas) ao princípio de sincronicidade de Jung. A fim de realizar os objetivos supramencionados, este trabalho prende-se, em sua primeira parte, tanto a um estudo das fontes de constituição do conhecimento no ocidente quanto a uma apreciação das tendências epistemológicas da ciência contemporânea, no sentido de situar adequadamente a questão da proposta da noção de totalidade não-fragmentada. De forma contígua a este fim, procede-se a pesquisa da obra de certas personalidades do cenário do conhecimento no ocidente, por se terem, reconhecidamente, norteado segundo um referencial de totalidade.

Efeitos das inomogeneidades da matéria em Cosmologias Aceleradas

The recent observational advances of Astronomy and a more consistent theoretical framework turned Cosmology in one of the most exciting frontiers of contemporary science. In this thesis, homogeneous and inhomogeneous Universe models containing dark matter and different kinds of dark energy are confronted with recent observational data. Initially, we analyze constraints from the existence of old high redshift objects, Supernovas type Ia and the gas mass fraction of galaxy clusters for 2 distinct classes of homogeneous and isotropic models: decaying vacuum and X(z)CDM cosmologies. By considering the quasar APM 08279+5255 at z = 3.91 with age between 2-3 Gyr, we obtain 0,2 < OM < 0,4 while for the j3 parameter which quantifies the contribution of A( t) is restricted to the intervalO, 07 < j3 < 0,32 thereby implying that the minimal age of the Universe amounts to 13.4 Gyr. A lower limit to the quasar formation redshift (zJ > 5,11) was also obtained. Our analyzes including flat, closed and hyperbolic models show that there is no an age crisis for this kind of decaying A( t) scenario. Tests from SN e Ia and gas mass fraction data were realized for flat X(z)CDM models. For an equation of state, úJ(z) = úJo + úJIZ, the best fit is úJo = -1,25, úJl = 1,3 and OM = 0,26, whereas for models with úJ(z) = úJo+úJlz/(l+z), we obtainúJo = -1,4, úJl = 2,57 and OM = 0,26. In another line of development, we have discussed the influence of the observed inhomogeneities by considering the Zeldovich-Kantowski-DyerRoeder (ZKDR) angular diameter distance. By applying the statistical X2 method to a sample of angular diameter for compact radio sources, the best fit to the cosmological parameters for XCDM models are OM = O, 26,úJ = -1,03 and a = 0,9, where úJ and a are the equation of state and the smoothness parameters, respectively. Such results are compatible with a phantom energy component (úJ < -1). The possible bidimensional spaces associated to the plane (a , OM) were restricted by using data from SNe Ia and gas mass fraction of galaxy clusters. For Supernovas the parameters are restricted to the interval 0,32 < OM < 0,5(20") and 0,32 < a < 1,0(20"), while to the gas mass fraction we find 0,18 < OM < 0,32(20") with alI alIowed values of a. For a joint analysis involving Supernovas and gas mass fraction data we obtained 0,18 < OM < 0,38(20"). In general grounds, the present study suggests that the influence of the cosmological inhomogeneities in the matter distribution need to be considered with more detail in the analyses of the observational tests. Further, the analytical treatment based on the ZKDR distance may give non-negligible corrections to the so-calIed background tests of FRW type cosmologies
