Design of materials and educational resources adapted to ETCS: project of application of the new technologies to teaching of History of the Spanish Language and its varieties

The adaptation to the new European Higher Education Area favors the assumption of the new technologies as one of the means that improve the quality of education and the process of student’s learning. The best assimilation of the theoretical and practical contents of the different subjects and the stimulus that the use of these resources for the independent learning of the student supposes, justify the attention lent to the formal aspects of the educational methodology, and to its consequent didactic process. The project that we presented finds its justification in the measures that the University of Cadiz has started up in the occasion of the process of European Convergence, and that are materialized, in this case, in the Call of Educative Innovation of the educational and investigating personnel of the European Project. Our work assumes as main target the optimization of the educational resources, from the possibilities that offer new technical means, with the creation of educational, audio-visual and computerized material, adapted to the contents of the implied subjects, and with a joint work of the teaching staff who allows the creation of a repository of computerized material that has stable character and that can be taken advantage of by the group in its later educational work. In this sense, this contribution tries to show the different lines of performance that the members of the project develop at the present time, and that takes shape in the creation of different resources as the elaboration from presentations in Power Point, the computerization of real samples of speech and the creation of a model that allows to elaborate computerized text commentaries, from hyperlinks and different linksUniversidad de Cádiz, Vicerrectorado de Tecnologías de la Información e Innovación DocenteInted2009 Proceedings C

The concept of finite limit of a function at one point as explained by students of non-compulsory secondary education

We review various educational studies of the mathematical concept of limit of a function at a point that indicate how colloquial uses of the terms “to approach,” “to tend toward,” “to reach,” “to exceed” and “limit” influence students’ conceptions of these terms. We then present the results of an exploratory study of this question performed with Spanish students in non-compulsory secondary education and analyze the responses they provide to justify the truth or falsity of statements related to the different characteristics of the concept of finite limit of a function at a point when they use these terms. Finally, we organize their answers according to the kinds of arguments made. Using the response profiles detected, we discuss the influence of everyday usage on the students’ arguments

The NADPH-Dependent thioredoxin reductase C-2-Cys peroxiredoxin redox system modulates the activity of thioredoxin x in arabidopsis chloroplasts

The chloroplast redox network is composed of a complex set of thioredoxins (Trxs), reduced by ferredoxin (Fdx) via a Fdx-dependent Trx reductase (FTR), and an NADPH-dependent Trx reductase with a joint Trx domain, NTRC, which efficiently reduces 2-Cys peroxiredoxins (2-Cys Prxs). Recently, it was proposed that the redox balance of 2-Cys Prxs maintains the redox state of f-type Trxs, thus allowing the proper redox regulation of Calvin-Benson cycle enzymes such as fructose 1,6-bisphosphatase (FBPase). Here, we have addressed whether the action of 2-Cys Prxs is also exerted on Trx x. To that end, an Arabidopsis thaliana quadruple mutant, ntrc-trxx-δ "2cp, which is knocked out for NTRC and Trx x, and contains severely decreased levels of 2-Cys Prxs, was generated. In contrast to ntrc-trxx, which showed a severe growth inhibition phenotype and poor photosynthetic performance, the ntrc-trxx-δ "2cp mutant showed a significant recovery of growth rate and photosynthetic efficiency, indicating that the content of 2-Cys Prxs is critical for the performance of plants lacking both NTRC and Trx x. Light-dependent reduction of FBPase was severely impaired in mutant plants lacking NTRC or NTRC plus Trx x, despite the fact that neither NTRC nor Trx x is an effective reductant of this enzyme. However, FBPase reduction was recovered in the ntrc-trxx-δ "2cp mutant. Our results show that the redox balance of 2-Cys Prxs, which is mostly dependent on NTRC, modulates the activity of Trx x in a similar way as f-type Trxs, thus suggesting that the activity of these Trxs is highly interconnected.Ministerio de Economía y Competitividad BIO2017-85195-C2-1-

Desigualdades en longevidad y calidad de vida entre Andalucía y España

ResumenFundamentoEl aumento experimentado en la esperanza de vida durante siglo XX hace más necesario el uso de indicadores que proporcionen información sobre la calidad de vida y su distribución en diferentes zonas geográficas. Para ello se describe, junto a la esperanza de vida (EV), la esperanza de vida sin discapacidad (EVSD) por sexo y edad, y se estima la magnitud de sus desigualdades entre Andalucía y España.Material y métodoCon los datos de mortalidad del Movimiento Natural de la Población, la Encuesta sobre Discapacidades, Deficiencias y Estado de Salud y las poblaciones del Instituto Nacional de Estadística del 1999 para Andalucía y España, se han construido las tablas de vida abreviadas, y a partir de ellas se ha calculado las EVSD mediante el método de Sullivan y se han obtenido la EV y la EVSD por edad y sexo de Andalucía y España.ResultadosLa esperanza de vida fue menor en Andalucía que en España en todas las edades en varones y mujeres: al nacer fue de 73,9 y 80,9 años para varones y mujeres en Andalucía y de 75,0 y 82,1 años en España. Las desigualdades entre Andalucía y España en la EVSD fueron mayores a todas las edades, tanto en varones como en mujeres: 66,0 y 69,0 años para varones y mujeres de Andalucía al nacer y de 68,3 y 72,0 en España.ConclusionesAndalucía tiene una menor longevidad y una peor calidad de vida que la media española, sobre todo en las mujeres mayores.AbstractBackgroundBecause of the increase in life expectancy (LE) throughout the twentieth century, indicators providing information on quality of life and its distribution in distinct geographical areas are required. We describe LE and life expectancy without disability (LEWD) by age and sex and estimate the magnitude of inequalities between Andalusia and Spain.Material and methodMortality data from the Natural Population Movement, the Survey of Disabilities, Deficiencies and Health Status, and the populations of the National Institute of Statistics for Andalusia and Spain in 1999 were used. Abbreviated life tables were constructed and were used to calculate LEWD through Sullivan's method. LE and LEWD by age and sex were obtained for Andalusia and Spain.ResultsLE was lower in Andalusia than in Spain in all age groups and in both sexes. At birth, LE was 73.9 years for men and was 80.9 years for women in Andalusia and was 75.0 years and 82.1 years in Spain respectively. Inequalities between Andalusia and Spain in LEWD were greater in all age groups both in men and in women: at birth LEWD was 66.0 years and 69.0 years for men and women in Andalusia and was 68.3 years and 72.0 years in Spain.ConclusionsLongevity and quality of life are lower in Andalusia than the mean for Spain, especially in elderly women

Realizing dynamic capabilities and organizational knowledge in effective innovations: the capabilities typological map

Purpose – This paper aims to shed light on the mechanisms that connect dynamic capabilities and organizational knowledge in the innovative process to offer a new theoretical and practical solution considering the microfoundations of knowledge management strategies. Design/methodology/approach – This research has emerged from an in-depth case study of an effective innovation (from just ethanol and sugar-production to an effective biomass plant). The study represents an “inductive inquiry,” useful to understand specific “organizational mechanisms” of innovation, where the main data came from in-depth interviews with 18 key actors. It proved to help search the development of a specific biomass plant, designed and implemented between 2000 and 2007 in a Brazilian ethanol and sugar-production large company, referred to here as “Energyplant.” Findings – This solution provides a new perspective based on the idea that dynamic capabilities are context-dependent and presents an original typological map that shows and materializes dynamic capabilities as teams of human-based resources. Managerial implications can be drawn from the capabilities typological map highlighting that, although identical dynamic capabilities are not required to change different firms, idiosyncratic dynamic capabilities perform universal knowledge functions that can be mapped, contributing to the planning of a specific innovation. Originality/value – While the dynamic capabilities research has been seen as one of the most vibrant topics in strategic management, scholars have recently stressed that dynamic capabilities continue to be underrated because the knowledge mechanisms that lead to effective innovations have not been adequately explored. The visual mapping is then applied to solve the reviewed theoretical problems, being also suggested to firms interested in change and adapting their capabilities to the requirements of the business environment

Retail competition with switching consumers in electricity markets

The ongoing transformations of power systems worldwide pose important challenges,both economic and technical, for their appropriate planning and operation. A key approach to improve the efficiency of these systems is through demand-side management, i.e., to promote the active involvement of consumers in the system. In particular, the current trend it to conceive systems where electricity consumers can vary their load according to real-time price incentives, offered by retailing companies.Under this setting, retail competition plays an important role as inadequate prices orservices may entail consumers switching to a rival retailer. In this work we consider a game theoretical model where asymmetric retailers compete in prices to increase their profits by accounting for the utility function of consumers. Consumer preferences for retailers are uncertain and distributed within a Hotelling line. We analytically characterize the equilibrium of a retailer duopoly, establishing its existence and uniqueness conditions. Furthermore, sensitivities of the equilibrium prices with respect to relevant model parameters are also provided. The duopoly model is extended to a multiple retailer case for which we perform an empirical analysis via numerical simulations. Results indicate that, depending on the retailer costs, loyalty rewards and initial market shares, the resulting equilibrium can range from complete competition to one in which a retailer have a leading or even a dominant position in the market, decreasing the consumers' utility significantly. Moreover, the retailer network configuration also plays an important role in the competitiveness of the systemAcknowledgements: The authors gratefully acknowledge financial support from the Spanish government through project MTM2013-

Análisis de tareas de cálculo de límites en un punto en las que intervienen identidades notables

Una de las dificultades identificadas en las investigaciones en Pensamiento Matemático Avanzado es la ruptura con el pensamiento algebraico y sus procedimientos. El análisis se apoya continuamente en habilidades algebraicas pero, al mismo tiempo, para conseguir dominar el pensamiento analítico se requiere alejarse del algebraico y tomar conciencia de las diferencias que se establecen entre ellos. En este trabajo se analiza la relación entre los aspectos estructurales y los errores que los estudiantes manifiestan cuando realizan tareas en las que se involucran identidades notables y los errores que los estudiantes manifiestan cuando calculan límites finitos de funciones en un punto, que corresponden a indeterminaciones del tipo 0/0 y, que se pueden resolver mediante la simplificación de fracciones algebraicas en las que aparecen identidades notables
