Contenidos digitales abierto y participación en la sociedad digital
Sergio álvarez,Manuel Gértrudix
Enlace , 2011,
Abstract: El propósito de este artículo es identificar y caracterizar la naturaleza de los procesos y contenidos abiertos enla participación de los individuos y colectivos en la sociedad digital. El trabajo realizado parte de una contextualizaciónteórica de los elementos que componen el objeto de estudio en el proceso de investigación y facilitar así, la comprensióny alcance de sus resultados. La metodología empleada es de corte cualitativo basado en el estudio de casos, centradoen el análisis de los recursos, estrategias y procesos cuando se produce, selecciona y difunden contenidos abiertosen la sociedad digital. Los resultados de este trabajo describen los fenómenos y vías de participación en la culturadigital; basados en el contexto de la cultura libre, se usan conceptos como: "contenidos generados por los usuarios oespectadores", "financiación de la multitud" y "producción de la gente común". Las conclusiones que pueden extraersede esta multiplicación de medios se resumen en el creciente potencial de los contenidos abiertos para generar recursosy modelos de participación en la sociedad digital.
La utilidad de los formatos de interacción músico-visual en la ense anza The Utility of Musico-visual Formats in Teaching
Manuel Gértrudix Barrio,Felipe Gértrudix Barrio
Comunicar , 2010, DOI: 10.3916/c34-2010-02-10
Abstract: Desde los presupuestos del aprendizaje por competencias, y su actual implantación en la mayor parte de los sistemas educativos internacionales, el artículo analiza la potencialidad educativa de la cultura popular a través de la utilización didáctica de los formatos de interacción músico-visual en el aula. Se defiende la necesidad de permear el concepto de alfabetización, integrando en el mismo los elementos que conforman el actual escenario de una sociedad digital altamente tecnológica, al tiempo que se recupera e inserta en el discurso de la escuela y en los procesos de aprendizaje que ésta motiva, los productos culturales que forman parte de la vivencia cotidiana de los adolescentes. El análisis de las propuestas de aprendizaje por competencias realizadas, entre otros, por la OCDE a través del Proyecto DESECO o el marco de referencia europeo definido a través de la recomendación del Parlamento y el Consejo Europeo, sirven de punto de partida para establecer una estrategia inicial que, desde la dimensión discursiva de los formatos de interacción músico-visual, permita un trabajo eficaz en el aula. Así, se evalúa la oportunidad que estos formatos de interacción músico-visual, y concretamente los videoclips, ofrecen como medios didácticos al servicio de una alfabetización digital que fomente un espíritu crítico, y se exploran algunas contribuciones concretas que se vislumbran en el desarrollo de competencias generales en Educación Secundaria Obligatoria. The paper discusses the educational potential of popular culture through the use didactic formats musicovisual interaction in the classroom. It is believed that popular culture, specifically music, is a particularly useful tool for learning. Considered by learning skills, and its current deployment in International educational systems. Especially, its implementation in the education Systems in Europe and Spanish. We live in a technological society, and therefore it is necessary to extend the concept of literacy to digital literacy. Elements of popular culture that are common for young people, such as video clips, should be incorporated. We analyze the competency learning proposals made by the OECD through the DESECO Project or the European framework defined by the recommendation of the European Parliament and Council. These proposals provide a starting point to establish an initial strategy, from the discursive dimension of interaction musicovisual formats, allowing for effective work in the classroom. For this reason, the article evaluates formats musico-visual interaction as teaching aids to serve a cr

Equilibrium Dynamics in the Neoclassical Growth Model with Habit Formation and Elastic Labor Supply  [PDF]
Manuel A. Gómez
Theoretical Economics Letters (TEL) , 2012, DOI: 10.4236/tel.2012.25087
Abstract: This note analyzes the equilibrium dynamics in the neoclassical growth model with habit-forming preferences and elastic labor supply. Habits enter into utility in a multiplicative way. The specification of the habit formation process comprises the particular cases of internal and external habits. Existence, uniqueness and saddle-path stability of the steady state are proved analytically.
Public Spending in a Model of Endogenous Growth with Habit Formation
Manuel A. Gómez
Discrete Dynamics in Nature and Society , 2010, DOI: 10.1155/2010/514329
Abstract: This paper introduces habit-forming preferences in a Barro-type endogenous growth model with productive public services. Government expenditure, which may be subject to congestion, is financed by distortionary income taxation. Different from the standard time-separable model, the presence of habits makes the economy feature transitional dynamics, which are solved in closed form. Setting the income tax so as to equate the elasticity of public services in production is shown to maximize both long-run growth and welfare as in the standard model. This second-best solution coincides with the first-best outcome only in the presence of proportional congestion. 1. Introduction Following the seminal work of Barro [1], the effect of productive government expenditure has been the subject of active research in the theoretical literature on endogenous growth (see, e.g., Irmen and Kuehnel [2], for a recent survey). This interest has been stimulated by empirical work, starting from Aschauer [3], providing compelling evidence that productive public spending has a positive impact on growth (see, e.g., the review by Romp and de Haan [4]). Barro [1] introduces the flow of government expenditure, which is fully financed by a distortionary income tax, as a productive input to private production. (Another strand of the literature, starting from Futagami et al. [5], considers that it is the accumulated stock of public capital, rather than the flow of current expenditure, that enters in the production function (see, e.g., Irmen and Kuehnel [2]).) Thus, public policy has two opposite effects on growth, which offset each other if the tax rate on income is equal to the elasticity of public spending in production. Under Cobb-Douglas technology, this growth-maximizing tax rate also maximizes intertemporal utility in a second-best sense. The ensuing literature has enriched the original Barro's setup to incorporate other relevant features such as, among others, adjustment costs [6], congestion [7, 8], public consumption services [9, 10], elastic labor supply [11], alternative government financing [9, 12], progressive taxation [13], rent-seeking [14, 15], finite lifetimes [16, 17], two countries [18], or stochastic growth [19, 20]. This paper adds to this literature by extending the Barro [1] model to incorporate habit-persistent preferences. In models with habit formation, individual's utility depends not only on her level of current consumption but also on how it compares to a reference level–-the habits stock. Recent empirical works by Chen and Ludvigson [21], Korniotis [22], and
THE WELFARE COST OF EXTERNAL HABITS: A QUANTITATIVE ASSESSMENT
Gómez,Manuel A;
Estudios de economía , 2010, DOI: 10.4067/S0718-52862010000100001
Abstract: this paper quantifies the welfare cost of consumption externalities in an endogenous growth model with habit formation. agent's utility depends on both current consumption and a reference consumption level determined by economy-wide average past consumption. although utility may be lower in the presence of consumption externalities, the welfare loss relative to the efficient growth path is found to be very small. this result is extremely robust to variations in the parameter values. however, there are relatively important differences in the timing of the welfare loss and in generational welfare.

Factores ambientales relacionados con la gravedad del asma
OYARZúN G.,MANUEL;
Revista chilena de enfermedades respiratorias , 2004, DOI: 10.4067/S0717-73482004000100004
Abstract: this article review the role played by indoor and atmospheric air pollutants as factors determining asthma severity. respiratory and health effects and sources of main indoor air pollutants are briefly reviewed. there is abundant evidence of asthmatic responses to indoor aeroallergens, such as exposure to house mite allergens. for pet allergens, some studies found that an early exposure in life was associated to sensitization and allergic disease, whereas others reported a protective effect. the effects of combustion indoor air pollutants have been less characterized. however, some studies suggest that they can be associated to exacerbations of asthma. environmental tobacco smoke (ets) exposure has been associated to exacerbation of asthma in childhood. moreover the prevalence of childhood asthma and adult hospital admissions for asthma has been related to ets exposure. exposure of atopic and asthmatic subjects to atmospheric air pollutants (o3 and no2 ) increases airways response to aeroallergens. therefore control of atmospheric pollutants might decrease any interaction with allergens in atopic and asthmatics
SUPLEMENTACIóN CON HIERRO
Olivares G,Manuel;
Revista chilena de nutrición , 2004, DOI: 10.4067/S0717-75182004000300001
Abstract: iron supplementation is one of the strategies used for preventing iron deficiency when the population at risk does not have access to iron fortified foods, or during pregnancy because of very high iron requirements that should be covered in a short period of time. in our country, based on the prevalencia of iron deficiency, suplementación has been addressed to the pregnant woman, starting from the second trimester of gestation and to infants not receiving iron-fortified foods. it would be of a high interest to consider the suplementación of women in fertile age what would allow them to begin pregnancy with adequate iron stores avoiding the adverse effects of iron deficiency. an appropriate motivation and education, utilization of the lower recommended iron doses, and use of iron compounds that have a low incidence of gastrointestinal adverse effects can improve the effectiveness of iron supplementation.
Qué se investiga en relación a enfermedad pulmonar obstructiva crónica en Chile
OYARZúN G.,MANUEL;
Revista chilena de enfermedades respiratorias , 2002, DOI: 10.4067/S0717-73482002000300009
Abstract: in order to have information on what is researched about chronic obstructive pulmonary disease (copd) in chile, a search about chilean publications in biomedical on copd research was carried out. medline and lilacs indices were reviewed from 1982 to 2001. additionally, the research abstracts on copd research presented at the five last chilean annual meetings on respiratory diseases were also reviewed. the most frequent research topics on copd in full papers published in biomedical journals were: ventilatory muscle training (28%), followed by physical activity in patients with copd (18%), use of non-invasive mechanical ventilation (15%) and pharmacological treatments. in the abstracts, the order of the most frequent topics on copd research was physical training (30%), use of non-invasive mechanical ventilation (20%), ventilatory muscle training (13%) and experimental animal research. annual average number of abstracts between 1997-99/ annual (1999-2001) average number of publication ratio was 2.9: 1 suggesting that out of 3 abstracts only one is published as a full paper. although a valuable research is being carried out in chile on ventilatory muscle physiology in copd, epidemiological and clinical research should be increased and improved, in order to obtain a better understanding of our copd patients
