Este trabajo aborda la posible contribución de la radio al envejecimiento activo. La ética comunicativa actual debe tener presentes los colectivos más vulnerables de la sociedad y uno de ellos es el de la vejez. Se recogen en el artículo los principales datos demográficos sobre población mayor, cuyo crecimiento es tal que se hace necesario un cambio de paradigma a la hora de abordar estos cambios, lo que se conoce como envejecimiento activo. Se plantea que la radio, por sus peculiares características, puede contribuir a promover dicho paradigma. Pero es necesario partir de datos objetivos y el artículo concluye presentando los datos y gráficos de la investigación realizada sobre la presencia de la vejez en los magazines matinales de las cuatro emisoras más importantes del país.

The sixties was a time of great interest for tourism development on the La Palma island. Various actions of public and private, as the policy of building a new airport, various tourist resorts, the tourism plan of 1968 or insular government also creating public entity "La Palma, Tourism SA” in 1969, will be the basis for future development of tourism on the island and will result push for private investment in this economic sector. Indeed, in the sixties, private investors had opened two hotels, while at least three others over a hundred beds each, weren´t finished.

It is usually assumed that Heraclitus is, exclusively, the philosopher of flux, diversity and opposition while Parmenides puts the case for unity and changelessness. However, there is a significant common understanding of things (though in differing contexts), not simply an accidental similarity of understanding. Both philosophers, critically, distinguish two realms: on the one hand, there is the one, common realm, identical for all, which is grasped by the ‘logos that is common’(Heraclitus) or the steady nous (Parmenides) that follows a right method in order to interpret the real. On the other hand, the realm of multiplicity seen and heard by the senses, when interpreted by ‘barbarian souls’, is not understood in its common unity. Analogously, when grasped by the wandering weak nous it does not comprehend the real’s basic unity. In this paper I attempt to defend the thesis that both thinkers claim that the common logos (to put it in Heraclitean terms) or the steady intellect (to say it with Parmenides) grasp and affirm the unity of the real.

La frontière entre le politique et l'intellectualisme militant est, d'ordinaire, ténue. Tout univers politico-constitutionnel est ainsi susceptible de faire les frais d'un martèlement doctrinal qui, à maints égards, relève davantage du construit que du donné. Résultante directe d'une construction parfois intéressée, le récit identitaire, à force de répétition, s'installera confortablement sur les sièges de l'imaginaire populaire. Il accèdera, au fil du temps, au statut de mythe pur et simple. Ce dernier, politiquement parlant, revêt de puissants effets aphrodisiaques. La présente thèse doctorale s'intéresse plus particulièrement aux mythes créés, depuis 1982, par un segment de la doctrine québécoise : en matière de droits linguistiques, objet principal de notre étude, Charte canadienne des droits et libertés et Cour suprême, toutes deux liguées contre le Québec, combineront leurs efforts afin d'assurer le recul du fait français dans la Belle Province. Quant aux francophones hors Québec, ceux-ci, depuis l'effritement du concept de nation canadienne-française, sont dorénavant exclus de l'équation, expurgés de l'échiquier constitutionnel. En fait, l'adoption d'un nationalisme méthodologique comme nouvelle orthodoxie politique et doctrinale rend ardue, en plusieurs sens, la conciliation de leur existence avec les paradigmes et épistémologie maintenant consacrés. Ainsi, et selon la logique du tiers exclu, une victoire francophone hors Québec signifiera, du fait d'une prétendue symétrie interprétative, un gain pour la communauté anglo-québécoise. Cette thèse vise à discuter de la teneur de diverses allégories établies et, le cas échéant, à reconsidérer la portée réelle de la Charte canadienne en matière linguistique. Il sera alors démontré que plusieurs lieux communs formulés par les milieux intellectuels québécois échouent au moins partiellement, le test de l'analyse factuelle. Celui-ci certifiera de l'exclusion, par la doxa, de toute décision judiciaire ou autre vérité empirique ne pouvant cadrer à même les paramètres, voire les prismes, de l'orthodoxie suggérée.

Most commercially available reverse osmosis (RO) and nanofiltration (NF) membranes are based on the thin film composite (TFC) aromatic polyamide membranes. However, they have several disadvantages including low resistance to fouling, low chemical and thermal stabilities and limited chlorine tolerance. To address these problems, advanced RO/NF membranes are being developed from polyimides for water and wastewater treatments. The following three projects have resulted from my research. (1) Positively charged and solvent resistant NF membranes. The use of solvent resistant membranes to facilitate small molecule separations has been a long standing industry goal of the chemical and pharmaceutical industries. We developed a solvent resistant membrane by chemically cross-linking of polyimide membrane using polyethylenimine. This membrane showed excellent stability in almost all organic solvents. In addition, this membrane was positively charged due to the amine groups remaining on the surface. As a result, high efficiency (> 95%) and selectivity for multivalent heavy metal removal was achieved. (2) Fouling resistant NF membranes. Antifouling membranes are highly desired for “all” applications because fouling will lead to higher energy demand, increase of cleaning and corresponding down time and reduced life-time of the membrane elements. For fouling prevention, we designed a new membrane system using a coating technique to modify membrane surface properties to avoid adsorption of foulants like humic acid. A layer of water-soluble polymer such as polyvinyl alcohol (PVA), polyacrylic acid (PAA), polyvinyl sulfate (PVS) or sulfonated poly(ether ether ketone) (SPEEK), was adsorbed onto the surface of a positively charged membrane. The resultant membranes have a smooth and almost neutrally charged surface which showed better fouling resistance than both the positively charged NF membranes and commercially available negatively charged NTR-7450 membrane. In addition, these membranes showed high efficiency for removal of multivalent ions (> 95% for both cations and anions). Therefore, these antifouling surfaces can be potentially used for water softening, water desalination and wastewater treatment in a membrane bioreactor (MBR) process. (3) Thermally stable RO membranes. Commercial RO membranes cannot be used at temperature higher than 45°C due to the use of polysulfone substrate, which often limits their applications in industries. We successfully developed polyimides as the membrane substrate for thermally stable RO membranes due to their high thermal resistance. The polyimide-based composite polyamide membranes showed desalination performance comparable to the commercial TFC membrane. However, the key advantage of the polyimide-based membrane is its high thermal stability. As the feed temperature increased from 25oC to 95oC, the water flux increased 5 - 6 times while the salt rejection almost kept constant. This membrane appears to provide a unique solution for hot water desalination and also a feasible way to improve the water productivity by increasing the operating temperature without any drop in salt rejection.

Discussion paper commissioned by the RSE for its official working group on BBC Charter Renewal. The paper sought to investigate evolving mobile digital platforms and audience habits. Beyond this the research was intended to highlight areas where the BBC might develop a more commercial strategy in the new charter period. The paper fed into the discussions around the RSE response to the government consultation on BBC Charter renewal. The paper is significant to measure the impact of research around interactive Second Screen activity in the media landscape.

Snapper (Pagrus auratus) is widely distributed throughout subtropical and temperate southern oceans and forms a significant recreational and commercial fishery in Queensland, Australia. Using data from government reports, media sources, popular publications and a government fisheries survey carried out in 1910, we compiled information on individual snapper fishing trips that took place prior to the commencement of fisherywide organized data collection, from 1871 to 1939. In addition to extracting all available quantitative data, we translated qualitative information into bounded estimates and used multiple imputation to handle missing values, forming 287 records for which catch rate (snapper fisher−1 h−1) could be derived. Uncertainty was handled through a parametric maximum likelihood framework (a transformed trivariate Gaussian), which facilitated statistical comparisons between data sources. No statistically significant differences in catch rates were found among media sources and the government fisheries survey. Catch rates remained stable throughout the time series, averaging 3.75 snapper fisher−1 h−1 (95% confidence interval, 3.42–4.09) as the fishery expanded into new grounds. In comparison, a contemporary (1993–2002) south-east Queensland charter fishery produced an average catch rate of 0.4 snapper fisher−1 h−1 (95% confidence interval, 0.31–0.58). These data illustrate the productivity of a fishery during its earliest years of development and represent the earliest catch rate data globally for this species. By adopting a formalized approach to address issues common to many historical records – missing data, a lack of quantitative information and reporting bias – our analysis demonstrates the potential for historical narratives to contribute to contemporary fisheries management.
