Scientifi c discourses on chronic pain without organic cause Incorporating gender perspective for pain resignifyng-repoliticizing

Chronic pain, without any organic or physical cause (DC), which in psycho-medical terminology is known as fi bromyalgia, (FM), is diagnosed each year to a considerable number of women in capitalistic societies. Our main interest in the following paper is to go in depth in the elaboration of this symptom, its treatment and the psychosocial effects, both in the social order as well as in the lives of the people who suffer from it. Our main goal in the following paper is to look deeper in the elaboration (conceptualization) of this symptom, its treatment and psychological affects, both in the social order as well as in the lives of the people who suffer from it, we are using linked speeches in Spanish magazines publications. The result has been the emergence of three hegemonic discourse positions: One position “scientist”, one “therapeutic of the conformity” position and one “economic and legalistic” position. Each of these has a specifi c feature, but on the whole, is enhanced, producing effects such as the absence of social context to explain the disease; disregard of gender differences in the management and treatment; the instrumentalization of pain to legitimize their practices and the subjection of women to the “psycho-biomedical” paradigm. In that way, a new signifi cance and politicization of the concept of pain is proposed.

the social economy as an alternative of self employment. profile of the entrepreneur in the andalusian labour companies

This paper provides a quantitative and qualitative analysis of the profile of the entrepreneur who decides to start business through a labor society in the context of the Autonomous Community of Andalucia. Thus, first the Social Economy is presented as an important alternative to creating and promoting employment, which seeks to combine economic and social objectives in the development of activities. Subsequently, focusing on labor companies, updated its importance in the regional economy for later data and through the analysis of two samples are available, set the attributes or most significant characteristics of these entrepreneurs.

The in-service teacher trainer: profile, career path and duties

This article is the result of a doctoral thesis that aims to understand the reality of teacher trainers at a given moment, when their professional role changes from being a managing training advisor to a role that is more centred on process counselling. Using in-depth interviews, we defined the personal and professional profile of training counsellors in the Balearic Islands, their career path, the process for their inclusion in Teacher Centres (CEP) and, finally, the duties and skills that they perform as teacher trainers. The data that has been collected shows the coexistence of different professional roles in the group of education advisors. Moreover, it also indicates a lack of definition of the profile needed to access an advisor's position. There are indeed some coincidences determining the access route to such a position when it comes to the teaching profession since their leadership qualities and group dynamics expertise are a common indicator in most cases. The research also shows that they are subjected not only to a wide range of roles and tasks but also to a vast array of competences required to tackle the education advisor's tasks.

Revisión sistemática de la producción española sobre rendimiento académico entre 1980 y 2011

El bajo rendimiento académico sigue siendo un problema de investigación de gran impacto social. Sin embargo, los resultados científicos no están teniendo repercusión en la mejora, ni en las políticas educativas. En este trabajo nos propusimos identificar, ordenar, analizar y extraer conclusiones sobre la producción española sobre rendimiento académico, con el fin de visualizarla y derivar problemas futuros objeto de investigación. Para ello se llevó a cabo un estudio de revisión en seis etapas, en el que se combinaron procedimientos metodológicos de investigación de síntesis y de investigación bibliométrica. Se identificaron las publicaciones en cuatro bases de datos españolas; posteriormente se analizaron y codificaron los datos extraídos alrededor de nueve indicadores: título, año, tipo de documento, editorial, autor, número autores, institución, comunidad autónoma y tema. Los resultados muestran una producción constante y creciente (1595 referencias), pero dispersa, tanto por el inmenso número de autores que publican, la mayoría con un solo trabajo, como por los lugares donde publican. Las temáticas más tratadas se refieren en primer lugar a modelos explicativos, diagnóstico y tratamiento; en segundo lugar se abordan los factores y variables determinantes del bajo y alto rendimiento académico; en tercer lugar se desarrollan estudios sobre legislación y de otras variables psicológicas y educativas en relación con el rendimiento. Este estudio supone una aproximación sintetizada de la producción sobre rendimiento académico en España, y un primer paso para investigaciones de síntesis posteriores, que nos permitan identificar buenas prácticas para el ejercicio de “prácticas basadas en la evidencia”, y otros problemas de investigación.

Instrumentos de evaluación utilizados en la formación inicial del profesorado y su coherencia para el desarrollo de competencias profesionales en los estudiantes: visión del alumnado, egresados y profesorado

El objetivo de este trabajo es analizar la frecuencia con que se utilizan diferentes instrumentos y procedimientos de evaluación desde el punto de vista del profesorado, del alumnado y de los egresados en la formación inicial de maestros y profesores especialistas en Educación Física, así como el grado de coherencia –relación- percibido por cada uno de esos grupos implicados entre dichos instrumentos y procedimientos de evaluación y el desarrollo de las competencias profesionales que se pretende adquieran los estudiantes. La muestra objeto de estudio está compuesta por 199 alumnos, 67 egresados y 53 profesores de las titulaciones de Magisterio (especialidad de Educación Física) y Ciencias de la Actividad Física y el Deporte de las universidades de Valladolid, Salamanca y León. Los resultados muestran una clara discrepancia entre los distintos grupos analizados, tanto en lo referido al tipo de instrumentos de evaluación utilizados, como en la valoración del grado de coherencia entre estos y el desarrollo de las competencias profesionales de los futuros maestros.

Analysis of the reading and comprehension control in scientific texts in high school students

Students' learning process can be negatively affected when their reading and comprehension control is not appropriated. This research focuses on the analysis of how a group of students from high school evaluate their reading comprehension in manipulated scientific texts. An analysis tool was designed to determine the students' degree of comprehension control when reading a scientific short text with an added contradiction. The results have revealed that the students from 1st and 3rd ESO do not properly self-evaluated their reading comprehension. A different behavior has been observed in 1st Bachillerato, where appropriate evaluation and regulation seem to be more frequent. Moreover, no significant differences have been found regarding the type of text, year or gender. Finally, as identified by previous research, the correlations between the students' comprehension control and their school marks have shown to have a weak relationship and inversely proportional to the students' age.

Social Networks Usage Profile: Descriptive study with students in the University of Murcia

Telematic tools are very important for our lives in the present era and moreover this idea is made more evident if we analyse young people behaviours. However, it seems that the possibilities that these tools allow subjects from a professional point of view, beyond the purely playful aspects, are still not fully exploited both by subjects, neither by educational institutions where they learn. Our work studies the uses of social media in the context of university students. In order to this we have designed a research based on quantitative methodology with a survey. We have applied a questionnaire to students in the University of Murcia. The questionnaire was answered by 487 students in the first half of 2014. The survey results confirm our hypothesis that social networks are part of the basic and habitual tools of communication between the youth of our university and eminently used for leisure purposes, and that the tools used for more academic activities are those allowing greater control of privacy.

La parroquia de San Miguel de Sagra y San Gil de Madrid en el siglo XVI. Aportaciones documentales

Una serie de documentos inéditos relativos a la antigua parroquia de San Miguel de Sagra y San Gil, localizada muy próxima a la entrada principal del Alcázar de Madrid, así como su posterior derribo y traslado en 1548 con nuevo edificio en el lado suroriental del Palacio, permite profundizar en un proyecto urbano largo tiempo madurado y culminado en la conformación de un espacio abierto y regularizado, emblemático y representativo, que resultó ser la plaza situada frente a la portada principal del Alcázar.

Alegoría: su pertinencia en la predicación y uso en "La novena maravilla"

En este artículo se focaliza el recurso de la alegoría como método exegético en la composición de los sermones panegíricos de Juan Espinosa Medrano (Perú, siglo XVII). Se traza el recorrido de la alegoría (y las humanidades en general) en relación –siempre tensa– con el cristianismo a lo largo de su historia; y se llega a la Contrarreforma y el uso exacerbado del método en la predicación barroca; particularmente en la oratoria sagrada de Espinosa Medrano, quien abarca elementos diversos y extraídos de distintas fuentes (filosofía natural, mitología clásica, tradición emblemática, relatos bíblicos), a los que hace funcionar como signos de otra verdad mayor, la sagrada. Si bien las preceptivas sagradas impulsaban una predicación más llana y simple, la profusión de alegorías mitológicas, que el autor resemantiza según su interés de guiar la interpretación, pueden explicarse por varias circunstancias, motivos de estudio en este trabajo.

De artista a andragogo. Experiencias educativas de docencia no reglada en cursos dirigidos por artistas contemporáneos.

This article focuses mainly on identifying innovative andragogical experiences and educational links established between contemporary artists and university students outside the formal teaching. Its structure consists of an introduction that defines the theoretical and contextual framework, the objectives pursued, the methodology and analytical development results. The analysis of educational concepts, resulting in the kind of knowledge and artistic andragogic, conceptually form a generative teaching in the context of non-formal teaching. Delimiting the complex responsibilities of university professors, linked to Art, through analysis of experiences in higher education andragogic which, initially part of the model of “artist educator” (Barrett, 1995; Laferrière, 2000), plunging into the innovative and alternative educational settings that are currently the compliance with the declaration of 2009 as the International Year of Creativity and Innovation.

The circle in the relationship between space and body. Photo-essay based on Isidro Blasco and the BAPNE method

This article demonstrates a visual study on the educational space in which the teaching of body percussion is carried out in universities. The methodological framework is chosen by the Visual Arts Based Educational Research, using the work of an artist as a conceptual and methodological model. The research remains notable (1) due to the theoretical reference to the BAPNE method, (2) due to the visual reference to the work of Isidro Blasco – especially with the piece “Shanghai Planet 2009” - ;(3) due to the parallelisms established between the object of study in this investigation -the spatial analysis- and the focuses of interest revealed by the art critics in relation to the work of this artist. By means of a visual speech formed with 7 photo-collages the relationship between body and educational space is visualized in the basic disposition of circular learning. The visual constructions by way of photo-collage and their aesthetic charge brings us closer to the intimacy of the educational space, in the style in which it is distributed to the students in the music classroom, the materialization of interpersonal relationships, the occupied and empty volumes.

Role of Bacterial Surface Structures on the Interaction of Klebsiella pneumoniae with Phagocytes

Phagocytosis is a key process of the immune system. The human pathogen Klebsiella pneumoniae is a well known example of a pathogen highly resistant to phagocytosis. A wealth of evidence demonstrates that the capsule polysaccharide (CPS) plays a crucial role in resistance to phagocytosis. The amoeba Dictyostelium discoideum shares with mammalian macrophages the ability to phagocytose and kill bacteria. The fact that K. pneumoniae is ubiquitous in nature and, therefore, should avoid predation by amoebae, poses the question whether K. pneumoniae employs similar means to counteract amoebae and mammalian phagocytes. Here we developed an assay to evaluate K. pneumoniae-D. discoideum interaction. The richness of the growth medium affected the threshold at which the cps mutant was permissive for Dictyostelium and only at lower nutrient concentrations the cps mutant was susceptible to predation by amoebae. Given the critical role of bacterial surface elements on host-pathogen interactions, we explored the possible contribution of the lipopolysaccharide (LPS) and outer membrane proteins (OMPs) to combat phagoyctosis by D. discoideum. We uncover that, in addition to the CPS, the LPS O-polysaccharide and the first core sugar participate in Klebsiella resistance to predation by D. discoideum. K. pneumoniae LPS lipid A decorations are also necessary to avoid predation by amoebae although PagP-dependent palmitoylation plays a more important role than the lipid A modification with aminoarabinose. Mutants lacking OMPs OmpA or OmpK36 were also permissive for D. discoideium growth. Except the LPS O-polysaccharide mutants, all mutants were more susceptible to phagocytosis by mouse alveolar macrophages. Finally, we found a correlation between virulence, using the pneumonia mouse model, and resistance to phagocytosis. Altogether, this work reveals novel K. pneumoniae determinants involved in resistance to phagocytosis and supports the notion that Dictyostelium amoebae might be useful as host model to measure K. pneumoniae virulence and not only phagocytosis. © 2013 March et al.

Host cell kinases, α5 and β1 integrins, and Rac1 signalling on the microtubule cytoskeleton are important for non-typable Haemophilus influenzae invasion of respiratory epithelial cells

Non-typable Haemophilus influenzae (NTHi) is a common commensal of the human nasopharynx, but causes opportunistic infection when the respiratory tract is compromised by infection or disease. The ability of NTHi to invade epithelial cells has been described, but the underlying molecular mechanisms are poorly characterized. We previously determined that NTHi promotes phosphorylation of the serine-threonine kinase Akt in A549 human lung epithelial cells, and that Akt phosphorylation and NTHi cell invasion are prevented by inhibition of phosphoinositide 3-kinase (PI3K). Because PI3K-Akt signalling is associated with several host cell networks, the purpose of the current study was to identify eukaryotic molecules important for NTHi epithelial invasion. We found that inhibition of Akt activity reduced NTHi internalization; differently, bacterial entry was increased by phospholipase C?1 inhibition but was not affected by protein kinase inhibition. We also found that a5 and ß1 integrins, and the tyrosine kinases focal adhesion kinase and Src, are important for NTHi A549 cell invasion. NTHi internalization was shown to be favoured by activation of Rac1 guanosine triphosphatase (GTPase), together with the guanine nucleotide exchange factor Vav2 and the effector Pak1. Also, Pak1 might be associated with inactivation of the microtubule destabilizing agent Op18/stathmin, to facilitate microtubule polymerization and NTHi entry. Conversely, inhibition of RhoA GTPase and its effector ROCK increased the number of internalized bacteria. Src and Rac1 were found to be important for NTHi-triggered Akt phosphorylation. An increase in host cyclic AMP reduced bacterial entry, which was linked to protein kinase A. These findings suggest that NTHi finely manipulates host signalling molecules to invade respiratory epithelial cells.

Evidence for a non-replicative intracellular stage of nontypable Haemophilus influenzae in epithelial cells

Nontypable Haemophilus influenzae (NTHi) is a Gram-negative, non-capsulated human bacterial pathogen, a major cause of a repertoire of respiratory infections, and intimately associated with persistent lung bacterial colonization in patients suffering from chronic obstructive pulmonary disease (COPD). Despite its medical relevance, relatively little is known about its mechanisms of pathogenicity. In this study, we found that NTHi invades the airway epithelium by a distinct mechanism, requiring microtubule assembly, lipid rafts integrity, and activation of phosphatidylinositol 3-kinase (PI3K) signalling. We found that the majority of intracellular bacteria are located inside an acidic subcellular compartment, in a metabolically active and non-proliferative state. This NTHi-containing vacuole (NTHi-CV) is endowed with late endosome features, co-localizing with LysoTracker, lamp-1, lamp-2, CD63 and Rab7. The NTHi-CV does not acquire Golgi- or autophagy-related markers. These observations were extended to immortalized and primary human airway epithelial cells. By using NTHi clinical isolates expressing different amounts of phosphocholine (PCho), a major modification of NTHi lipooligosaccharide, on their surfaces, and an isogenic lic1BC mutant strain lacking PCho, we showed that PCho is not responsible for NTHi intracellular location. In sum, this study indicates that NTHi can survive inside airway epithelial cells.

Klebsiella pneumoniae triggers a cytotoxic effect on airway epithelial cells

Klebsiella pneumoniae is a capsulated Gram negative bacterial pathogen and a frequent cause of nosocomial infections. Despite its clinical relevance, little is known about the features of the interaction between K. pneumoniae and lung epithelial cells on a cellular level, neither about the role of capsule polysaccharide, one of its best characterised virulence factors, in this interaction.
