Micropolítica de los espacios públicos interiores

Este ensayo intenta resaltar los posibles puentes de oración y diálogo que existen entre la teoría política contemporánea y algunos teóricos de la tradición psicoanalítica del siglo veinte, como es el caso de su propio inventor, Sigmund Freud, y también dos de sus más controvertidos discípulos: Melanie Klein y Heinz Kohut. En concreto, me propongo reflexionar en torno al problema de la interioridad política del individuo-ciudadano y de cómo, a partir del descubrimiento freudiano de las dimensiones no conscientes del pensamiento (Ello), categorías cuya genealogía se entiende como plenamente política –tales como omnipotencia/impotencia, infancia e identidad– son transferidas o metaforizadas a fin de alumbrar la comprensión del psiquismo individual. En armonía con una forma de pensar retórica, el artículo aborda ciertos tropoi del psicoanálisis, el complejo de Edipo y el relato de Ulises y su hijo Telémaco, como dos mitos que simbolizan las políticas del abandono y de la reparación en los espacios públicos interiores del ciudadano.

Problemàtiques en l'estudi i investigació del "Dot Painting o Dot Art Movement" Aborigen austràlià

L'objecte d'estudi de la següent memòria són les obres de l'anomenat, en la literatura anglosaxona, "Dot Art Movement o Dot Painting"; un moviment artístic índigena contemporani engendrat entre la dècada dels 70 i els 80 del segle passat a les comunitats de Papunya i Yuendumu en el cor del Desert Australià. La memòria s'articula entorn les principals problemàtiques a les que s'enfronta la definició i descripció de l'anomenat "Dot Art Movement o Dot Painting" dins el context de consum i recepció de les obres a Europa. Aquestes problemàtiques, sobretot conceptuals però també metodològiques, són descrites entorn tres grans apartats: el fet "primitiu", el fet "aborigen" i el fet del "Dot Art Movement o Dot painting". A través d'aquests tres àmbits la memòria presenta diverses herències històriques de caràcter eurocèntric, amb base al període colonial, que dificulten la proliferació d'interpretacions i noves aproximacions vers la recepció europea de les obres d'aquest moviment artístic.

Estudio de parámetros circuitales de resonadores

El objetivo de este proyecto consiste en el estudio de los parámetros circuitales (condensadores, bobinas…) de un resonador, realizado con estructuras microstrip, donde permita obtener unos resultados de esos parámetros circuitales cambiando los valores físicos del diseño, tales como la longitud y la anchura del resonador a partir de las medidas de los parámetros S. Para llevar a cabo dicho trabajo, se desarrolla en primer lugar toda la teoría necesaria de resonadores. Empezando por el funcionamiento y la estructura del resonador diseñado, y mostrando especial interés en el modelado de dicho resonador. Seguidamente, se estudia y analiza su comportamiento a través de las simulaciones de los parámetros S. Una vez se ha estudiado y analizado su comportamiento, se procede con las modificaciones de los parámetros físicos y se analiza a través de las simulaciones de los parámetros S cómo afectan estas modificaciones en los parámetros circuitales. Donde se utilizan una serie de herramientas que agilizan la extracción de los valores de los parámetros circuitales del resonador.

Methods and representativeness of European surveys in children and adolescents: the KIDSCREEN study

Background: The objective of the present study was to compare three different sampling and questionnaire administration methods used in the international KIDSCREEN study in terms of participation, response rates, and external validity. Methods: Children and adolescents aged 8–18 years were surveyed in 13 European countries using either telephone sampling and mail administration, random sampling of school listings followed by classroom or mail administration, or multistage random sampling of communities and households with self-administration of the survey materials at home. Cooperation, completion, and response rates were compared across countries and survey methods. Data on non-respondents was collected in 8 countries. The population fraction (PF, respondents in each sex-age, or educational level category, divided by the population in the same category from Eurostat census data) and population fraction ratio (PFR, ratio of PF) and their corresponding 95% confidence intervals were used to analyze differences by country between the KIDSCREEN samples and a reference Eurostat population. Results: Response rates by country ranged from 18.9% to 91.2%. Response rates were highest in the school-based surveys (69.0%–91.2%). Sample proportions by age and gender were similar to the reference Eurostat population in most countries, although boys and adolescents were slightly underrepresented (PFR <1). Parents in lower educational categories were less likely to participate (PFR <1 in 5 countries). Parents in higher educational categories were overrepresented when the school and household sampling strategies were used (PFR = 1.78–2.97). Conclusion: School-based sampling achieved the highest overall response rates but also produced slightly more biased samples than the other methods. The results suggest that the samples were sufficiently representative to provide reference population values for the KIDSCREEN instrument.

El Alimento y la muerte en la festividad de Día de Muertos en México

En la mayor parte de México se celebra los días 1 y 2 de noviembre el Día de Muertos, celebración reconocida por la UNESCO como Obra Maestra del Patrimonio Oral e Intangible de la Humanidad. La fiesta, que ha sido objeto de estudio de numerosos trabajos antropológicos, ha sido relegada en el ámbito de la estética, tanto así, que antropólogos como Stanley Brandes subrayan la carencia de un tratamiento procesual de la dimensión artística de la festividad.

Arte Outsider: Aproximación a la construcción artística de las manifestaciones creativas al margen del sistema del Arte

Para este trabajo se ha querido mirar afuera de los límites del arte tal y como se concibe en occidente. Dicho de otra forma, con mirar más allá no se hace referencia al arte de otras culturas, pues, de hecho, no nos movemos de la nuestra. Lo que se pretende a continuación, es la contemplación en la producción “artística” que se crea al margen de los dominios del “arte” oficial. Con esto puede parecer que nos inclinemos hacia las manifestaciones antisistemas que surgen en ambientes no institucionales como las paredes de las calles de las ciudades o en espacios de Internet. Por el contrario, se quiere tener en cuenta a aquellos individuos que, no perteneciendo al mundo del arte, pero impulsados por las mismas fuerzas expresivas que siente un artista “profesional”, generan imágenes plásticas de gran ímpetu y valor estético, tales como los niños, los pacientes y discapacitados mentales a causa de psicopatologías o trastornos, o visionarios y médiums espirituales. En definitiva, se prestará atención a individuos social y culturalmente marginados.

Further insights in trichothiodistrophy: a clinical, microscopic, and ultrastructural study of 20 cases and literature review

Background: Trichothiodistrophy (TTD) is a rare autosomal recessive condition that is characterized by a specific congenital hair shaft dysplasia caused by deficiency of sulfur associated with a wide spectrum of multisystem abnormalities. In this article, we study clinical, microscopic, and ultrastructural findings of 20 patients with TTD with the aim to add further insights regarding to this rare condition. Additionally, analyses of our results are compared with those extracted from the literature in order to enhance its comprehensibility. Materials and Methods: Twenty cases of TTD were included: 7 from Mexico and 14 from Spain. Clinical, microscopic, scanning electron microscopy (SEM) studies and X-ray microanalysis (XrMa) were carried out in all of them. Genetic studies were performed in all seven Mexican cases. Patients with xeroderma pigmentosum and xeroderma pigmentosum/TTD-complex were excluded. Results: Cuticular changes and longitudinal crests of the hair shaft were demonstrated. These crests were irregular, disorganized, following the hair longest axis. Hair shaft sulfur deficiency was disposed discontinuously and intermittently rather than uniformly. This severe decrease of sulfur contents was located close to the trichoschisis areas. Only five patients did not show related disturbances. Micro-dolichocephaly was observed in five cases and represented the most frequent facial dysmorphism found. It is also remarkable that all patients with urologic malformations also combined diverse neurologic disorders. Moreover, three Mexican sisters demonstrated the coexistence of scarce pubic vellus hair, developmental delay, onychodystrophy, and maxillar/mandibullar hypoplasia. Conclusions: TTD phenotype has greatly varied from very subtle forms to severe alterations such as neurologic abnormalities, blindness, lamellar ichthyosis and gonadal malformations. Herein, a multisystem study should be performed mandatorily in patients diagnosed with TTD.

Setting priorities in clinical and health services research: Properties of an adapted and updated method

Objectives: The objectives of this study is to review the set of criteria of the Institute of Medicine (IOM) for priority-setting in research with addition of new criteria if necessary, and to develop and evaluate the reliability and validity of the final priority score. Methods: Based on the evaluation of 199 research topics, forty-five experts identified additional criteria for priority-setting, rated their relevance, and ranked and weighted them in a three-round modified Delphi technique. A final priority score was developed and evaluated. Internal consistency, test–retest and inter-rater reliability were assessed. Correlation with experts’ overall qualitative topic ratings were assessed as an approximation to validity. Results: All seven original IOM criteria were considered relevant and two new criteria were added (“potential for translation into practice”, and “need for knowledge”). Final ranks and relative weights differed from those of the original IOM criteria: “research impact on health outcomes” was considered the most important criterion (4.23), as opposed to “burden of disease” (3.92). Cronbach’s alpha (0.75) and test–retest stability (interclass correlation coefficient = 0.66) for the final set of criteria were acceptable. The area under the receiver operating characteristic curve for overall assessment of priority was 0.66. Conclusions: A reliable instrument for prioritizing topics in clinical and health services research has been developed. Further evaluation of its validity and impact on selecting research topics is required
