Una monografia inèdita de Gaziel sobre la premsa espanyola: context, comentari i edició

Text inèdit de Gaziel, prologat pel professor Manuel Llanas, que constitueix una monografia sobre la situació de la premsa diària espanyola. Es tracta d’una anàlisi històrica sobre el període comprès entre 1875 i 1942, amb una visió prospectiva final. L’autor divideix la periodització en tres fases: i) el passat (1874-1936); ii) el present, referit a la situació en la immediata postguerra; iii) el futur, on s’apunta una concepció normativa del periodisme. En cadascuna d’aquestes fases, la premsa és estudiada des de la dimensió política, professional, industrial i econòmica.

Toward 'Complexics' as a transdiscipline

The proposed transdisciplinary field of ‘complexics’ would bring together allcontemporary efforts in any specific disciplines or by any researchersspecifically devoted to constructing tools, procedures, models and conceptsintended for transversal application that are aimed at understanding andexplaining the most interwoven and dynamic phenomena of reality. Our aimneeds to be, as Morin says, not “to reduce complexity to simplicity, [but] totranslate complexity into theory”.New tools for the conception, apprehension and treatment of the data ofexperience will need to be devised to complement existing ones and toenable us to make headway toward practices that better fit complexictheories. New mathematical and computational contributions have alreadycontinued to grow in number, thanks primarily to scholars in statisticalphysics and computer science, who are now taking an interest in social andeconomic phenomena.Certainly, these methodological innovations put into question and againmake us take note of the excessive separation between the training receivedby researchers in the ‘sciences’ and in the ‘arts’. Closer collaborationbetween these two subsets would, in all likelihood, be much moreenergising and creative than their current mutual distance. Humancomplexics must be seen as multi-methodological, insofar as necessarycombining quantitative-computation methodologies and more qualitativemethodologies aimed at understanding the mental and emotional world ofpeople.In the final analysis, however, models always have a narrative runningbehind them that reflects the attempts of a human being to understand theworld, and models are always interpreted on that basis.

The Emerging Human Rights Revolution: The Beginning of the Fifth Historical Process in the Consolidation of Human Rights

Emerging human rights are destined to modify, improve and transform a number of already traditional concepts so as to achieve greater guarantees and protection for the rights of individuals and collectivities. One of the big changes that will be brought about by the concept and conception of emerging human rights is that, following on from the processes of positivization, generalization, internationalization and specification, they represent the beginning of the fifth historical process in the consolidation of human rights, namely the process of interaction. A number of breakthroughs have already been achieved, such as the recognition of emerging biocultural rights in the recently adopted Nagoya Protocol on access to genetic resources and shared benefits.

Richard Rorty i una aproximació pragmatista al liberalisme polític de John Rawls

Aquest article es proposa explorar la possibilitat d'apropar a la concepció del liberalisme polític metafilosòfic de John Rawls des del punt de vista pragmatista de Richard Rorty. La proposta està motivada per les similituds que es poden observar entre elles respecte de la finalitat i la sortida d'una concepció política. El resultat final de l'article és ambigua: d'una banda, no sembla tan descabellat afirmar que la teoria de Rawls es pot llegir sense més dificultats des d'una perspectiva pragmàtica, d'altra banda, hi ha alguns aspectes importants en els quals un liberalisme polític de Rawls segueix sent incompatible amb una concepció política de Rorty

Ecomateriais: desenvolvimento e aplicação de materiais porosos funcionais para proteção ambiental

Fundamental aspects of the conception and applications of ecomaterials, in particular porous materials in the perspective of green chemistry are discussed in this paper. General recommendations for description and classification of porous materials are reviewed briefly. By way of illustration, some case studies of materials design and applications in pollution detection and remediation are described. It is shown here how different materials developed by our groups, such as porous glasses, ecomaterials from biomass and anionic clays were programmed to perform specific functions. A discussion of the present and future of ecomaterials in green chemistry is presented along with important key goals.

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

Sustainable Waste-to-Energy Production: Performance Evaluation of Distributed Generation fuelled by Landfill Gas

The environmental impact of landfill is a growing concern in waste management practices. Thus, assessing the effectiveness of the solutions implemented to alter the issue is of importance. The objectives of the study were to provide an insight of landfill advantages, and to consolidate landfill gas importance among others alternative fuels. Finally, a case study examining the performances of energy production from a land disposal at Ylivieska was carried out to ascertain the viability of waste to energy project. Both qualitative and quantitative methods were applied. The study was conducted in two parts; the first was the review of literatures focused on landfill gas developments. Specific considerations were the conception of mechanism governing the variability of gas production and the investigation of mathematical models often used in landfill gas modeling. Furthermore, the analysis of two main distributed generation technologies used to generate energy from landfill was carried out. The review of literature revealed a high influence of waste segregation and high level of moisture content for waste stabilization process. It was found that the enhancement in accuracy for forecasting gas rate generation can be done with both mathematical modeling and field test measurements. The result of the case study mainly indicated the close dependence of the power output with the landfill gas quality and the fuel inlet pressure.

Processo de transferência de tecnologia da universidade para a indústria: estudo de caso envolvendo a conversão de glicerol

Currently, public policy has encouraged innovation in universities and also transference of technology to the industry. Another important stage to be considered would be the registration or filing of a patent and the economical viability study. Government programs, such as the innovation incentive program, among others, should facilitate popularization and promote interest by industry. In this work we described the steps, from the conception of the idea to the scale up going through its interest by the industry. The case study is about the glycerol conversion utilizing modified niobia as catalysts.

Concepções de licenciandos em química sobre visualizações no ensino de ciências em dois países: Brasil e Portugal

In this work, the beliefs of undergraduate students from Brazil and Portugal on the use of visual tools in teaching chemistry, which have increasingly been introduced in the areas of teaching/learning in these two countries in recent years, have been investigated. An interpretative analysis of the results shows little familiarity of students with specific points of the theme, beyond a poor conception about the way the visualization tools influence the construction of scientific concepts.

Química verde: a evolução de um conceito

This fact shows how concern over developing "greener" processes has played a prominent role in the scientific community. In this context, the scope of this work encompasses an analysis of the evolution of the theme since its conception to the present. This analysis elucidates how bibliographic output on "Green Chemistry" is distributed worldwide. Moreover, the main journals on the subject were listed and ranked, according to impact factor.

Mikroyrittäjä ja yrityksen kasvu

Tämän tutkimuksen tarkoituksena on selvittää mitkä tekijät ovat mikroyrityksen kasvun edellytyksenä ja mitkä tekijät ovat kasvun esteinä. Tutkimuksen taustalla on mikroyritysten yleisesti vähäinen kasvuhalukkuus. Tässä tutkimuksessa yrittäjien kasvuaikomuksia tarkastellaan kasvun prosessimalliin tukeutuen ja mikroyritysten kasvuun vaikuttavia tekijöitä tarkastellaan Perrenin mikroyrityksen kasvuun vaikuttavien tekijöiden mallin avulla. Tutkimuksessa on käytetty kvalitatiivista tutkimusmenetelmää. Tutkimus on toteutettu haastattelututkimuksena, jossa on haastateltu mikroyrittäjiä Päijät-Hämeessä Lahden ja Hollolan alueilla. Tämän tutkimuksen mukaan mikroyritysten kasvuun vaikuttavat yrittäjän tahtotila ja kyky yrityksen kehittämiseen sekä yrittäjän riskinottokyky että suotuisat ympäristölliset olosuhteet. Näiden tekijöiden puuttuminen estää kasvun. Yrityksen kasvua estäviä muita tekijöitä ovat tutkimuksen mukaan mikroyritysten liiallinen paikallisuus, yhteistyön vähäisyys sekä yrittäjän liiallinen kietoutuminen liiketoimintaan että toiminnan liian vähäinen strateginen suunnittelu.

Leibniz's theory of bodies: monadic aggregates, phenomena, or both?

Leibniz's conception of bodies seems to be a puzzling theory. Bodies are seen as aggregates of monads and as wellfounded phenomena. This has initiated controversy and unending discussions. The paper attempts to resolve the apparent inconsistencies by a new and formally spirited reconstruction of Leibniz's theory of monads and perception, on the one hand, and a (re-)formulation and precisation of his concept of preestablished harmony, on the other hand. Preestablished harmony is modelled basically as a covariation between the monadic and the ideal realm.

Love and rationality: on some possible rational effects of love

In this paper I defend the idea that rather than disrupting rationality, as the common-sense conception has done it, love may actually help us to develop rational ways of thinking and acting. I make the case for romantic or erotic love, since this is the kind of love that is more frequently associated with irrationality in acting and thinking. I argue that this kind of love may make us develop epistemic and practical forms of rationality. Based on an analysis of its characteristic action tendencies, I argue that love may help us to develop an instrumental form of rationality in determining the best means to achieve the object of love. It may also narrow down the number of practical considerations that may help us to achieve our goals. Finally, love may generate rational ways of belief-formation by framing the parameters taken into account in perception and attention, and by bringing into light only a small portion of the epistemic information available. Love may make us perceive reality more acutely.

Bayle et l'éthique épicurienne

L'éthique épicurienne a exercé sur Bayle une attraction dont on ne tient pas toujours suffisamment compte. Nous nous proposons de recueillir les diverses observations faites par Bayle concernant cette théorie afin de montrer qu'il y trouvait a) une explication convaincante des motifs de la conduite humaine, b) la plus exacte conception philosophique du bonheur, c) la meilleure méthode pour éduquer moralement les êtres humains et d) un argument décisif contre les philosophies qui, en ignorant la force du plaisir, proposaient un idéal de vertu condamné à l'échec.
