Between the Museum and the Street: Roberto Matta's Works in Chile during the Unidad Popular

This article seeks to contribute to the study of the work Roberto Matta made in Chile in the early 1970s by focusing on a series of painted arpilleras made at Museo Nacional de Bellas Artes and El primer gol del pueblo chileno, a mural created in collaboration with the muralist group Brigada Ramona Parra. I argue that this body of work was largely informed by the ideals of the Unidad Popular and that the artist's presence in the country might have contributed to the institutional validation of popular practices such as crafts and muralism in the local artistic scene.     

Entre la pampa del lenguaje y el alambrado de la escritura: la mancha roja como síntoma de la ambigüedad de lo real en La ocasión de Juan José Saer

La presencia recurrente del color rojo en La ocasión de Saer desempeña una función desestabilizadora en relación a la representación figurativa. En el artículo se establecen analogías entre esta función y el elemento voluble, no mimético de la pintura que el pensador e historiador de arte, Georges Didi-Huberman, denomina como “pan” en contraste con el detalle, categoría asociada con el carácter icónico de la pintura. Al igual que el “pan”, las manchas rojas en la novela apuntan a la dimensión de lo real que se resiste a la legibilidad y señala los límites de la narrativa realista. Saer se vale de contrastes cromáticos para aludir a tensiones políticas y epistemólogicas y a las paradojas de escribir una novela situada en el siglo diecinueve pero incorporando la experiencia literaria del siglo veinte.     

Administrative Innovations and Accountability Failures: The Termination of the Spanish Telecommunications Agency

We discuss how far accountability practices may be relevant to the success of independent regulators in countries without a tradition of administrative autonomy. We develop a conceptualisation of agency accountability failures and develop an analytical framework to examine the life and termination of the Spanish regulatory agency for telecommunications, CMT (Comisión del Mercado de las Telecomunicaciones - Telecommunications Market Commission). We argue that the CMT’s termination was related, among other reasons, to accountability failures in its institutional design. The paper relies on a variety of sources, including legislation, literature, media coverage, and semistructured interviews with agency officials and several stakeholders.     

Striking hard rock veins. Multinational Corporations and Miners’ Unions in Mexico and the United States, 1906-1952

ABSTRACT

This paper analyzes simultaneous strikes during the first half of the 20th century in North America. The transformation of production in copper, lead, zinc, and silver mining districts determined the formation of a working class that operated between Mexico and the United States. Therefore, the labor conflicts combined market circumstances and management-imposed homologation of work structures across firm divisions with the international coordination of miners. The paper describes the emergence, growth, and demise of a regional industrial system.     

STR analysis of artificially degraded DNA-results of a collaborative European exercise

Degradation of human DNA extracted from forensic stains is, in most cases, the result of a natural process due to the exposure of the stain samples to the environment. Experiences with degraded DNA from casework samples show that every sample may exhibit different properties in this respect, and that it is difficult to systematically assess the performance of routinely used typing systems for the analysis of degraded DNA samples. Using a batch of artificially degraded DNA with an average fragment size of approx. 200 bp a collaborative exercise was carried out among 38 forensic laboratories from 17 European countries. The results were assessed according to correct allele detection, peak height and balance as well as the occurrence of artefacts. A number of common problems were identified based on these results such as strong peak imbalance in heterozygous genotypes for the larger short tandem repeat (STR) fragments after increased PCR cycle numbers, artefact signals and allelic drop-out. Based on the observations, strategies are discussed to overcome these problems. The strategies include careful balancing of the amount of template DNA and the PCR cycle numbers, the reaction volume and the amount of Taq polymerase. Furthermore, a careful evaluation of the results of the fragment analysis and of automated allele calling is necessary to identify the correct alleles and avoid artefacts.     

Tissue concentrations of MDMA and its metabolite MDA in three fatal cases of overdose

The recreational use of amphetamine derivatives has become increasingly popular in our country in past recent years. Their use is especially common among young people participating in dance parties known as "raves." As a direct consequence of their increased use, the number of fatal cases in which these compounds have been involved have increased dramatically since the second half of the last decade. In our laboratory, we have registered 25 cases related to amphetamine derivatives use since 1996. Three of them were deeply studied and the results obtained are presented in this paper. This information may be useful for the interpretation of the results obtained in toxicological analysis in the cases in which death may be attributed to MDMA use.     

Glucose and lactate in vitreous humor compared with the determination of fructosamine for the postmortem diagnosis of diabetes mellitus

Diabetes mellitus is a chronic metabolic illness responsible for a great number of deaths. In postmortem diagnosis, because of the difficulty involved in interpreting blood glucose levels and relatively nonspecific pathologic features, biochemical markers in vitreous humor are useful. The aim of this study was to compare the results obtained for the combined determination of lactate and glucose with fructosamine levels recorded in the vitreous humor of two diagnostic groups (one diabetic and the other nondiabetic). The authors intended to ascertain the capacity of different markers measured in vitreous humor to diagnose diabetes mellitus. Fifty-one cadavers (mean age, 58.7 years; standard deviation, 17.09) were studied. The mean postmortem interval was 16.4 hours (standard deviation, 9.05). Cases were assigned to two diagnostic groups according to whether they were previously diagnosed as either diabetic or nondiabetic. Statistically significant differences for glucose, fructosamine, and the sum values of glucose and lactate were found between the two diagnostic groups. The highest levels were obtained in the group of cases with a previous diagnosis of diabetes mellitus. After the comparison of receiver operating characteristic curves, the sum values of glucose and lactate in vitreous humor is a better predictor of antemortem diabetes mellitus than the fructosamine.
