La modificación a la Constitución Política de México en 1983, generando un cambio en la asignación de gasto público, pasando de un Estado eminentemente económico, a uno, aparentemente interesado en la promoción del desarrollo social, donde se esperarían efectos en la construcción de ciudadanía. Para esta hipótesis, se realiza un análisis exploratorio de la Encuesta de Percepción de la calidad de Vida en el Distrito Federal (2012), utilizando un modelo Probit, los resultados muestran que la confianza en las instituciones es un elemento determinante para el ejercicio de la ciudadanía, y con ello tener menor probabilidad que las personas consideren a los programas sociales no como un instrumento de control político sino como parte de sus derechos sociales.

En el artículo se analizan los programas y políticas instrumentadas por el gobierno mexicano desde 1848 en la región fronteriza norte. El objetivo central de todos ellos ha sido integrar económica, política y socialmente esa región al resto del país. Se evalúan aquí los resultados obtenidos en relación con el objetivo mencionado, y se concluye que tal objetivo nunca se ha logrado; el autor cree por tanto necesario cuestionar seriamente la validez de la integración como elemento fundamental en la política regional y urbana en la frontera norte de México.

Research identifies segments of the voting population by use of the media in the region of Puno. It was conducted under the application of probabilistic sampling, a questionnaire was administered by personal interview to a sample of 323 potential voters, the data was collected based on personal characteristics and use of media; five indicators of this relationship they are chosen, those who participated in the multiple correspondence analysis. The most representative personal characteristics were: 42,1% of potential voters are 20 to 34 years, 30.3% are engaged in the study as the main activity, 37,2% are center-right political trend. On the use of media 76,5% if you use the internet, with television (87,3%) frequently use the medium for information on daily events. We identified four segments, the first segment covers 51,8% of potential voters, they being under 34 years, intraday use the internet, is not politically defined and communicated via television or internet. The second segment includes 12,69% of potential voters, who work for the private sector, use the Internet once or twice a week for information and are defined politically center-right. The third segment covers 6,5% of potential voters, aged between 50 and 69, use the internet less than once a week and are defined center-left. The fourth segment includes 29,72% of potential voters, aged between 34-69 years old, do not

Este trabajo presenta la escala de Actitudes ante la Polftica de Planificación de Instalaciones Deportivas (APPID), que evalua las preferencias de los ciudadanos sobre las caracterísicas de las instalaciones deportivas que preferirían que se construyera, ante dos alternativas contrapuestas. La factorización de los once items que la componen en una muestra representativa de la Comunidad Valenciana ha demostrado la existencia de tres factores: "énfasis en la calidad vs. en la cantidad de las instalaciones", "énfasis en la concentración vs. en la dispersión de las instalaciones", y "énfasis en las instalaciones orientadas hacia un enfoque comunitario y de barrio vs. enfoques alternativos". Ademas de la descripción de la escala, se estudian las relaciones que los tres factores descritos presentan con las variables sociodemograficas de los encuestados (edad, nivel socioeconómico, nivel de estudios y tamaño de la población de residencia). Los analisis de regresión realizados muestran que las variables sociodemográficas contribuyen a explicar un porcentaje reducido de la varianza de los tres factores de la escala APPID ; This paper presents the scale about Attitudes toward Politics of Sport Facilities Planning (APPID). Their 11 dicotomic items request for inteviewed people to tty his or her preference about characteristics of sport facilities that there must be built. Three factors had been obtained: "enphasis on quality vs. amount of facilities", "emphasis on geographical concentration vs. dispersion of facilities" and "emphasis on facilities oriented at a comunitary focus vs. other alternative focuses". The paper describes the scale and studies the relationship between the three described factors and a set of socio-demographic variables (age, socio-economic level, academic level, and population level of local town). Regression analysis pointed out reveal that socio-demographic variables explain a little amount of the varience of the three factors of APPID scale

Arthroderma vanbreuseghemii has been identified molecularly as the causative agent of dermatophytosis in a flock of sheep. It is necessary to explore new treatment alternatives because antifungals are not approved for use on small ruminant animals in the European Union. Antimicrobial photodynamic therapy (aPDT) has been shown to be effective for the treatment of dermatophytosis in humans. It is based on the application of a photosensitizer such as methylene blue (MB) that is activated by visible light to generate reactive oxygen species that are cytotoxic to cells. The use of daylight to perform aPDT (aDL-PDT) avoids the requirement of specific equipment because it uses sunlight to activate the photosensitizer. The aim of our study is to determine the efficacy of aDL-PDT using a 1% MB solution to treat dermatophytosis caused by A. vanbreuseghemii in ewes. Two different topical protocols (1% MB solution spray applications once or twice a week) were assayed in two groups of five infected animals. Twenty-five infected sheep were untreated. All the sheep were exposed to sunlight every day for an approximate duration of 10 h for a total of four weeks. At the end of the study, all the animals treated with aDL-PDT showed the same clinical response to both protocols. In contrast, the animals exposed only to sunlight required an additional two to four weeks before their infections resolved. Conclusion: aDL-PDT with 1% MB solution demonstrates efficacy, safety and efficiency in the treatment of dermatophytosis in sheep.

According to the calculations involved, the solutions must consider to run on specialized hardware as Graphical Processing Units (GPUs) or Field Programmable Gate Arrays (FPGAs), among others. In the case of a Shack-Hartmann wavefront sensor is finally selected, the wavefront slopes can be computed using centroid or correlation algorithms. Most of the developments are designed using centroid algorithms, but precision ought to be taken in account too, and then correlation algorithms are really competitive. This paper presents an FPGA-based wavefront slope implementation, capable of handling the sensor output stream in a massively parallel approach, using a correlation algorithm previously tested and compared to the centroid algorithm. Time processing results are shown, and they demonstrate the ability of the FPGA integer arithmetic in the resolution of AO problems. The selected architecture is based in today's commercially available FPGAs which have a very limited amount of internal memory. This limits the dimensions used in our implementation, but this also means that there is a lot of margin to move real-time algorithms from the conventional ; This work has been partially supported by "Programa Nacional de Diseño y Producción Industrial" (Project DPI 2006- 07906) of the "Ministerio de Educación y Ciencia" of the Spanish Government, and by "European Regional Development Fund" (ERDF).
