Sostenibilidad y gobernanza
Menéndez Viso, Armando
Arbor : Ciencia, Pensamiento y Cultura , 2005,
Abstract: The word sustainability is nowadays commonly related to a fuzzy array of concepts, like nature, environment, ecology, preservation or development. The first task of this chapter will be to establish some clear limits to that fuzzy set of ideas, correcting its environmental bias and stressing its moral elements. Once defined, it will be possible to check whether the notion of sustainability could help in achieving good governance, and how. It will be shown that, although sustainability works well as a filter -especially to discard damaging policies-, it has no political content at all. Sustainability could constitute a useful rhetorical resource, but it is absolutely meaningless without being associated to a concrete discourse or proposal. Si a una persona no especialmente informada se le habla hoy de sostenibilidad, lo más probable es que acuda a su cabeza una serie de ideas comúnmente asociadas al término: naturaleza, medio ambiente, ecología, conservación, desarrollo, etc. La primera tarea de estas páginas consistirá, precisamente, en especificar, filtrar y acaso extender esta serie de ideas. Después se intentará averiguar si puede ayudar a emprender una buena acción de gobierno, y cómo. La conclusión a la que se llegará es que la sostenibilidad resulta eficaz como criterio de selección -especialmente para descartar acciones de gobierno perniciosas- y debe desempe ar el papel de un ideal regulativo, pero no ofrece programas concretos de buen gobierno. La retórica de la sostenibilidad da juego (permite al menos cuatro figuras recurrentes, como se verá), pero no proporcionará resultado alguno si el discurso que recurre a ella no posee su propio contenido.

Abstract: this article offers a perspective on recent developments in bioethics, a field in which the distinction between fact and value is pervasive. by surveying how the word “value” is used in principle- based, mainstream biomedical ethics, it is shown that some uses enforce an essentialist tendency to speak of values as freestanding entities.as an illustration and explanation of the increasing pervasiveness of this language, both in english-speaking and spanish-speaking bioethics, we describe the role of “value talk” in recent writings by diego gracia.we focus on how his proposal of a methodology for bioethics uses the fact/value dichotomy, and analyse his position in relation to the agenda for the debate on the concepts of health and disease proposed by george khushf. as a conclusion, we suggest an alternative way of thinking about values in order to overcome the dichotomy.

Characterization of Doped Amorphous Silicon Thin Films through the Investigation of Dopant Elements by Glow Discharge Spectrometry: A Correlation of Conductivity and Bandgap Energy Measurements
Pascal Sánchez,Olaya Lorenzo,Armando Menéndez,Jose Luis Menéndez,David Gomez,Rosario Pereiro,Beatriz Fernández
International Journal of Molecular Sciences , 2011, DOI: 10.3390/ijms12042200
Abstract: The determination of optical parameters, such as absorption and extinction coefficients, refractive index and the bandgap energy, is crucial to understand the behavior and final efficiency of thin film solar cells based on hydrogenated amorphous silicon (a-Si:H). The influence of small variations of the gas flow rates used for the preparation of the p-a-SiC:H layer on the bandgap energy, as well as on the dopant elements concentration, thickness and conductivity of the p-layer, is investigated in this work using several complementary techniques. UV-NIR spectrophotometry and ellipsometry were used for the determination of bandgap energies of four p-a-SiC:H thin films, prepared by using different B 2H 6 and SiH 4 fluxes (B 2H 6 from 12 sccm to 20 sccm and SiH 4 from 6 sccm to 10 sccm). Moreover, radiofrequency glow discharge optical emission spectrometry technique was used for depth profiling characterization of p-a-SiC:H thin films and valuable information about dopant elements concentration and distribution throughout the coating was found. Finally, a direct relationship between the conductivity of p-a-SiC:H thin films and the dopant elements concentration, particularly boron and carbon, was observed for the four selected samples.

Abstract: the development of a 2 % dorzolamide eye solution to treat patients with ocular hypertension, having open angle glaucoma, pseudoexfoliative glaucoma and other secondary open-angle glaucoma began with the study of the formulation components by replacing some excipients stated in the reviewed literature, and the physical, chemical, biological, microbiological and rheological properties were analyzed during the pre-formulation studies. an analytical technique was devised for the finished product. three batches of formulation were prepared and then stored in low density polyethylene flasks with master batch of 5 ml capacity, manufactured in situ by the bottle pack filler. these reservoirs were exposed at 30 ± 2 °c room temperature for 24 months and at 40 ± 2 oc accelerated temperature for 6 months and relative humidity of 75 %, according to the requirements set by the state center for drug control. at the beginning and at the end of the microbiological study, there was proved the sterility of each batch, the achieved results were satisfactory. after complying with all described quality parameters, the drug was registered in the cuban regulatory body for its safe use in the treatment of the above-mentioned diseases. this drug is being manufactured at industrial level and thus marketed.
Newspapers Coverage of Spain and the United States: A Comparative Analysis  [PDF]
Antonio V. Menéndez Alarcón
Sociology Mind (SM) , 2012, DOI: 10.4236/sm.2012.21009
Abstract: This article assesses the content of foreign news coverage in the United States and Spain. It draws on content analysis of two U.S. and two Spanish newspapers over a 28-month period, during 2005-2007 and in 2009. The results show that the content of these newspapers tends to be more negative when covering politics. However, there was a major change in the type of coverage in the Spanish newspapers from the period 2005-2007 to 2009. Coverage of U.S. politics in 2009 was much more positive than in the previous period studied. These findings suggest that newspapers contribute to an overall unfavorable representation of these countries for their respective populations. Also, when covering international news, newspapers are less independent from their government agendas than they claim; supporting critical research findings that mainstream media is vulnerable to “news management” by the government.

Abstract: health situation in contemporary world demands to society to place in a firth level of analysis questions like justness, promotion and prevention of health, quality of the attention, the ethical dilemmas, the recognition of the technological necessities of health in the national policy as an important factor for its development, and the use of proper technologies. for this reason of the most up-to-date literature in the last aspect, is made, with the purpose of contributing to the knowledge and broadcasting of a controversial but effective topic
Metodología cualitativa: varios problemas y reiteradas omisiones
Menéndez,Eduardo L.;
Index de Enfermería , 2012, DOI: 10.4321/S1132-12962012000100014
Abstract: from recognize the important contributions of the approaches and qualitative techniques to the study and intervention on health/illness/attention-prevention processes, this article drew and analyzes the domain of certain guidelines which have a negative impact or, at least, generated certain biases in quality production, which tend to exclude substantive aspects of the studied reality. the main analyzed here are as follows: a) the denial or, at least, a reluctance to make hypothesis, including interpretative ones; b) tendency to simplify increasingly qualitative techniques; c) the limited use of one of the main qualitative techniques, as in the case of observation, although participant observation is usually mentioned; d) trend strong to work almost exclusively with the social representations, discourses, narratives and/or experiences, leaving aside practices or assuming that the representations are equivalent to practices.
Magallania (Punta Arenas) , 2010, DOI: 10.4067/S0718-22442010000200007
Abstract: the aim of this paper is to contribute, from a bioarchaeological perspective, to the discussion about the model of economic intensification and diet broadening of hunter-gatherer populations in northeastern patagonia previously proposed by different authors. the underlying presuposition is that such process would have detectable effects in the intra-and interpopulational distribution of health and oral function indicators. to test this proposition, we analyzed temporal trends in the prevalence of different dental and periodontal relevant indicators (caries, abscesses and loss of antemortem teeth, periodontitis, tilting and lipping) in a collection formed by three diachronic subsamples of skulls from the río negro valley covering the last 3.600 years ab 14c. the results show that the prevalence of caries, periodontal disease and lipping tend to increase over time, while those of antemortem tooth loss, abscesses and tilting decrease. taken together, these temporal trends are consistent with the hypothesis of increased consumption of plant resources, particularly those with cariogenic potential (i.e. high starches content), after 1.000 ab.
Modelos de atención de los padecimientos: de exclusiones teóricas y articulaciones prácticas
Menéndez,Eduardo L.;
Ciência & Saúde Coletiva , 2003, DOI: 10.1590/S1413-81232003000100014
Abstract: in many latin american societies - especially in mexico - there is a diversity of care illness models, which are considered in an isolated and even antagonistic way by state health sector. this happens by living out the observation of individual and group practices which shows the narrow and continual relationship between this models. this paper describes particular relations between biomedicine and selfcare to show the constant transaction process between them. in first place some basic biomedical and selfcare characteristics are considered, then we observe the transaction between them with special attention to drugs prescription and selfmedication. transaction process is usually ignored by biomedicine and selfmedication process specially criticised by it. we are in the presence of a paradox because biomedicine and state health sector constantly promotes selfcare process which involves selfmedication. we notice that this takes place without a reflection on articulation and consequences of this transactions on health/illness/care process. we propose to think about this process in view of its intentional use by health services.
