Población y consumo. Una reconstrucción de las poblaciones consumidoras de leche en España 1925-1981

Este artículo se organiza en los siguientes apartados. En el primero, se presentan las fuentes y los datos de las estadísticas españolas sobre consumo de leches de origen animal y se discute las limitaciones del análisis basado en los valores medios. A continuación se presentará una metodología de corrección y ajuste de estos indicadores y a partir de la cual podrán inferirse las distribuciones de consumo del conjunto de la población española. En el segundo, se sigue con la aplicación de este procedimiento a los datos provinciales españoles comprendidos entre 1925 y 1981 y se comentan los resultados básicos obtenidos. Por último, se profundiza en el estudio de las tendencias de consumo a lo largo de ese período tanto a través del análisis de las estructuras de consumo como de sus pautas territoriales. La conclusión situará brevemente los resultados principales en el contexto de la transición nutricional española en el siglo XX y cerrará con unas observaciones sobre la naturaleza de la metodología aplicada, sus limitaciones y posibilidades.

Biomphalaria occidentalis paraense, 1981 in the state of Minas Gerais, Brazil

A population of Biomphalaria occidentalis was found for the first time in the State of Minas Gerais. It was probavly introduced into the Várzea das Flores dam, in the municipality of Contagem, the area o0f study, during fish stocking in 1985. There is possibility of "competitive exclusion"between that species and B. glabrata, previously the only Biomphalaria found in the region. The present geographical distribution of B. occidentalis in Brazil is listed.

Use of isozyme patterns in the identification of Biomphalaria tenagophila (D'Orbigny, 1835) and B. occidentalis (Paraense, 1981) (Gastropoda: Planorbidae)

Two sibling species of Biomphalaria, B. tenagophila and B. occidentalis were identified using isozyme patterns obtained by horizontal gel electrophoresis. Six diagnostic enzymatic loci were identified in digestive gland homogenates. The results enable us to distinguish the species, calculate the Nei's coefficient of genetic similarity, and provide a basis for making inferences about the pattern of these two planorbid species colonization and distribution.

Development and Consequences of Referendum Campaigns in Switzerland, 1981-1999

Since the early 1990s, new forms of referendum campaigns have emerged in the Swiss political arena. In this paper, we examine how referendum campaigns have transformed in Switzerland, focusing on a number of features: their intensity, duration and inclusiveness (i.e., the variety of actors involved). These features are assumed to change in the long run in response to societal changes and in the short run as a function of variations in elite support. We further argue that public knowledge of ballot issues depends on the characteristics of campaigns. To formally test our hypotheses, we draw on advertisement campaigns in six major Swiss newspapers in the four weeks preceding each ballot from 1981 to 1999 and develop a structural equation model. We indeed find that the duration of referendum campaigns has increased over time, while their inclusiveness has decreased. Most importantly, we find that pub­lic knowledge is strongly related to the characteristics of campaigns

Binding of d-methadone, l-methadone, and dl-methadone to proteins in plasma of healthy volunteers: role of the variants of alpha 1-acid glycoprotein.

The plasma concentrations of alpha 1-acid glycoprotein (AAG), albumin, triglycerides, cholesterol, and total proteins, as well as the plasma binding of racemic, d-methadone, and l-methadone were measured in 45 healthy subjects. The AAG phenotypes and the concentrations of AAG variants were also determined. The measured free fractions for racemic, d-methadone, and l-methadone were, respectively, 12.7% +/- 3.3%, 10.0% +/- 2.9%, and 14.2% +/- 3.2% (mean +/- SD). A significant correlation was obtained between the binding ratio (B/F) for dl-methadone and the total AAG concentration (r = 0.724; p less than 0.001). A multiple stepwise regression analysis showed that AAG was the main explanatory variable for the binding of the racemate. When concentrations of AAG variants were considered, a significant correlation was obtained between the binding ratio of dl-methadone and orosomucoid2 A concentration (r = 0.715; p less than 0.001), a weak correlation between dl-methadone and orosomucoid1 S concentration (r = 0.494; p less than 0.001), and no correlation between dl-methadone and orosomucoid1 F1 concentration (r = 0.049; not significant). Similar findings were obtained with the enantiomers. This study shows the importance of considering not only total AAG but also concentrations of AAG variants when measuring the binding of methadone and possibly of other drugs in plasma.

Trends in cancer mortality in Mexico, 1981-2007.

The objective of this study was to provideinformation on recent trends in cancer mortality in Mexico. We analyzed data provided by the World Health Organization, using joinpoint analysis to detect changes in trends between 1981 and 2007. For most cancers, mortality was upward but started to decline in the late 1980's/early 1990's for both sexes. Overall cancer mortality was 75.53/100 000 men, world standard, and 69.2/100 000 women in 2005-2007. Mortality from uterine cancer declined by approximately 2.5% per year in the 1990s, and by approximately 5% per year in the last decade, but its rates remained exceedingly high (9.7/100 000 in 2005-2007). Other major declines over recent years were those of stomach cancer (approximately 2.5% per year, with rates of 6.6/100 000 in men and 4.9/100 000 in women in 2005-2007) and lung cancer (2-2.5% per year, 11.0/100 000 in men and 4.5/100 000 in women in 2005-2007). Mortality leveled off only since the early 1990s for breast and prostate, and since the late 1990s for colorectal cancer. Death rates from cancer in Mexico remained low on a worldwide scale and showed favorable trends over more recent calendar years. Mortality from (cervix) uterine cancer still represents a major public health priority in this country.

LMM: an OWL-DL metamodel to represent heterogeneous lexical knowledge

In this paper we present a Linguistic Meta-Model (LMM) allowing a semiotic-cognitive representation of knowledge. LMM is freely available and integrates the schemata of linguistic knowledge resources, such as WordNet and FrameNet, as well as foundational ontologies, such as DOLCE and its extensions. In addition, LMM is able to deal with multilinguality and to represent individuals and facts in an open domain perspective.

Le Christ au miroir de la photographie contemporaine (1981-2011)

Depuis une trentaine d'années, les représentations de la figure de Jésus se sont multipliées en photographie. De la séquence narrative du photographe américain Duane Michals (Christ in New York, 1981) au chemin de croix de Wim Delvoye (Viae Crucis, 2006), en passant par la série I.N.R.I. (1997-98) de Bettina Rheims, les Photographies apocryphes (1994-98) d'Olivier Christinat, les Seven Bible Scenes (1998) de Rauf Mamedov, Ecce homo (1996-98) d'Elisabeth Ohlson, Jesus is my Homeboy (2003) de David LaChapelle ou encore South Soudan (2006) de Vanessa Beecroft, l'intérêt pour la figure christique dans le champ profane est incontestable. Le phénomène dépasse d'ailleurs les frontières géographiques, culturelles et confessionnelles.¦Cette thèse de doctorat réunit un important fonds iconographique qui démontre l'intérêt actuel pour la figure du Christ et la grande diversité des démarches et des profils des artistes. Cet important corpus est analysé selon trois perspectives. La première partie est consacrée au médium photographique, à ses liens étroits avec la sainte Face depuis le cliché du suaire de Turin en 1898, et depuis l'ambitieux projet photographique (1898) de Fred Holland Day qui incame le Christ dans ses nombreuses réinterprétations de la vie de Jésus.¦La deuxième partie de ce travail interroge l'emploi des formules iconographiques chrétiennes archétypales et questionne les références christiques utilisées par les artistes au travers de poses, d'attitudes, de gestes repris de chefs-d'oeuvre de l'art religieux, tant dans le domaine de la photographie d'art que dans la publicité ou la photographie de presse. L'usage du texte, la place des Ecritures dans les projets actuels sont aussi abordés, notamment autour de la question de la possibilité de raconter la vie de Jésus et des stratégies de mises en scène employées pour traduire les récits en images.¦Enfin, la dernière partie porte plus particulièrement sur les usages de la figure de Jésus, souvent alter ego de l'artiste, mais surtout porte-parole. À la suite des luttes socio- politiques des années 1970, la figure de Jésus est réinvestie par les minorités et Jésus incarne alors les combats d'artistes qui se réapproprient la représentation du Christ pour qu'elle corresponde à l'image qu'ils voient dans leur propre miroir (ex. Renee Cox, Yo Mama's Last Supper, 1996). Cet usage revendicateur, souvent doublé d'un goût non dissimulé pour la provocation (ex. Andres Serrano, Piss Christ, 1987), a souvent suscité la polémique. La question de la réception des oeuvres constitue un point essentiel de cette recherche qui tâche d'analyser la figure christique au miroir de la photographie contemporaine et qui conclut que le Christ est en réalité miroir des artistes eux-mêmes.
