La gestación de libros digitales y de bibliotecas virtuales en el marco de la Unión Europea (y el caso concreto de Espa a)
Enrique Martín Martín
Caracteres : Estudios Culturales y Críticos de la Esfera Digital , 2012,
Abstract: The purpose of this article is to state the methods of scanning used by the company Digibís. Throughout these pages we will state the kind of business of this company and their greatest achievements, in order to expose the projects of development of virtual libraries in the EU in general and particularly in Spain.
El conocimiento nutricional apenas altera las prácticas de alimentación: el caso de las madres de clases populares en Andalucía
Martín Criado,Enrique;
Revista Espa?ola de Salud Pública , 2007, DOI: 10.1590/S1135-57272007000500008
Abstract: many prevention-oriented public health policies consist of informative campaigns. these campaigns are based on the idea that information is the key to changing the practices on the part of the population thinking that, once provided with the necessary information, the subjects would change their living habits to more healthy ones. however, many studies have refuted this belief: there is a major gap between what is known about nutrition and actual everyday eating habits. an analysis is provided of this overall dynamic in the case of working-class mothers based on the results of qualitative research done in andalusia on eating habits and discourses. here also, we find a major gap between what is known about nutrition and actual everyday eating habits. in this article, an analysis is made of the reasons for this discrepancy as well as of the dynamics leading to continual distortions and reinterpretations of the messages given out by the health authorities. based on these analyses, recommendations are proposed with a view to public health policy: instead of general informative campaigns, more localized actions or actions which would have a bearing on the material living conditions would be more effective.

Cabilia: la problemática génesis del concepto de habitus Kabylia: the problematic genesis of the concept of habitus
Enrique Martín Criado
Revista mexicana de sociología , 2013,
Abstract: En libros como Le sens pratique, Pierre Bourdieu sustenta su teoría del habitus con ejemplos de una región argelina, Cabilia. En ellos, Cabilia aparece como una sociedad tradicional, pero en textos anteriores Bourdieu la había presentado como la región más moderna de Argelia. En el presente artículo se analizan esta discordancia y sus condiciones de producción: Bourdieu requería presentar Cabilia como una sociedad tradicional con el fin de sustentar su teoría del habitus. Esto sirve para reflexionar sobre algunas características del habitus, como su coherencia, la importancia de la socialización primaria en la explicación de la acción, y la normalidad del ajuste del habitus a una situación. In books such as Le sens pratique, Pierre Bourdieu uses examples from a region in Algeria, Kabylia, to support his habitus theory. Kabylia is depicted as a traditional society, although in previous texts Bourdieu had presented it as the most modern region of Algeria. This article analyzes this discrepancy and the conditions that create it. Indeed, Bourdieu needed to portray Kabylia as a traditional society to support his habitus theory. This is the basis for reflection on the coherence of this element and the importance of primary socialization to explain action and the normality of adjusting a habitus to a situation.
Las tallas grandes perjudican seriamente la salud. La frágil legitimidad de las prácticas de adelgazamiento entre las madres de clases populares
Martín-Criado, Enrique
Revista Internacional de Sociologia , 2010,
Abstract: The article defends an analysis that considers discourses as strategic moves. It takes as an example the discursive oscillations and contradictions on weight control of working class mothers: the intention to lose weight is asserted and denied. These contradictions are due to their difficult position between two contradictory norms: the slimness norm and the value of the sacrificed good mother. The tension between both norms allows us to understand discourse oscillations, as well as practices. These try to balance the care of the self with the legitimacy of the good mother. El artículo defiende la potencialidad de un análisis que considere los discursos como jugadas estratégicas. Para ello parte de las oscilaciones y contradicciones en los discursos de madres de clases populares en torno al control del peso: la pretensión de adelgazar se afirma y se niega. Estas contradicciones se deben a su difícil posición entre dos normas contradictorias: la norma de delgadez y el valor de buena madre entregada. La tensión entre ambas nos permite entender las oscilaciones del discurso, pero también sus prácticas. éstas intentan conciliar el cuidado de sí con la legitimidad de la buena madre.
La construcción de los problemas juveniles
Enrique Martín-Criado
Nómadas , 2005,
Abstract: La definición de los problemas sociales no depende de las características objetivas de los mismos, sino de dinámicas de construcción donde juegan un papel fundamental los intereses de los actores que intervienen en esta construcción. A su vez, esta definición produce efectos políticos. Se analizan las dinámicas de construcción y los efectos políticos de los “problemas juveniles”.
Homoclinic tangencies and hyperbolicity for surface diffeomorphisms
Enrique R. Pujals,Martín Sambarino
Mathematics , 2000,
Abstract: We prove here that in the complement of the closure of the hyperbolic surface diffeomorphisms, the ones exhibiting a homoclinic tangency are C^1 dense. This represents a step towards the global understanding of dynamics of surface diffeomorphisms.
Dynamic Control of Cell Cycle and Growth Coupling by Ecdysone, EGFR, and PI3K Signaling in Drosophila Histoblasts
Nikolay Ninov,Cristina Manjón,Enrique Martín-Blanco
PLOS Biology , 2012, DOI: 10.1371/journal.pbio.1000079
Abstract: Regulation of cell proliferation has been extensively studied in cultured cell systems that are characterized by coordinated growth and cell-cycle progression and relatively uniform cell size distribution. During the development of multicellular organisms, however, growth and division can be temporally uncoupled, and the signaling pathways that regulate these growth programs are poorly understood. A good model for analyzing proliferation control in such systems is the morphogenesis of the Drosophila adult abdominal epidermis by histoblasts. These cells undergo a series of temporally regulated transitions during which neither cell size nor division rate is constant. The proliferation of histoblasts during metamorphosis is uniquely amenable to clonal analysis in combination with live imaging. Thereby, we show that abdominal histoblasts, which grow while in G2 arrest during larval stages, enter a proliferative stage in the pupal period that is initiated by ecdysone-dependent string/Cdc25 phosphatase transcription. The proliferating histoblasts have preaccumulated stores of Cyclin E, which trigger an immediate S phase onset after mitosis. These rapid cell cycles lack a G1 phase and result in a progressive reduction of cell size. Eventually, the histoblasts proceed to a stage of slower proliferation that, in contrast to the preceding, depends on epidermal growth factor receptor (EGFR) signaling for progression through the G2/M transition and on insulin receptor/PI3K-mediated signaling for growth. These results uncover the developmentally programmed changes coupling the growth and proliferation of the histoblasts that form the abdominal epidermis of Drosophila. Histoblasts proceed through three distinct stages: growth without division, division without growth, and growth-coupled proliferation. Our identification of the signaling pathways and cell-cycle regulators that control these programs illustrates the power of in vivo time-lapse analyses after clone induction. It sets the stage for the comprehensive understanding of the coordination of cell growth and cell-cycle progression in complex multicellular eukaryotes.
