The importance of myth in contemporary art: myth, poetry and women

This project is intended to prove the prevalent importance of myth in contemporary art and, more specifically, to highlight how myth and poetry have shaped and reflected ideas of womanhood over time. A selection of significant literary periods, authors and works from the Renaissance to our days have been chosen in order to provide a wide scope of the evolution that the portrayal of women has undergone. Special attention has been paid to the way in which a group of selected poets have contributed to the construction and deconstruction of traditional Judeo-Christian and Greco-Roman myths strongly attached to patterns of male dominance.

World Library and Information Congress: 75th IFLA General Conference and Assembly.

L"edició del 2009 de la trobada de l"IFLA s"ha celebrat a Milà. La maquinària de l"organització va funcionar amb precisió per a aquest esdeveniment. Després d"anys de regularitat en les trobades per tot el món, l"IFLA funciona com un autòmat, una d"aquestes màquines perfectes, tant que podria continuar uncionant en les formes amb exemplar artifici. És un trobada singular, que aplega, a la vegada, la reunió de l"organització, un congrés mundial i una fira comercial; tot això amanit amb una ciutat diferent cada any i un finançament que depèn de la bona marxa de tot l"esdeveniment. En certa mesura, l"IFLA és un aparador de la professió, al qual assisteixen bibliotecaris de tot el món i de centenars d"institucions, amb tot el que suposa d"artificiositat en la representació d"entitats i promoció; un espai de reflexió, amb ponències i debats de molt variat interès que poden trobar-se, generalment, en altres esdeveniments; i una posada a punt dels treballs de tots els comitès, que tenen un complex desenvolupament previ i una àrdua tasca desenvolupada amb generositat per tots els participants.

Blanc sota negre. Treballs des de l'imperceptible / 3. Freya Powell: I'll smile and I'm not sad. I altres passats presents

Les instal·lacions de vídeo de la primera exposició de Freya Powell a Barcelona conviden a una meditació dels vincles entre la memòria i l'arxiu, l'enregistrament, el repertori i les traces de la Història. En aquesta exposició es tensa un fil entre la memòria dels condemnats a mort nordamericans, la memòria de la Segona Guerra Mundial, la de l'artista pròpia i els diferents mapes del món sota la història colonial. És un fil que pregunta pel nostre vincle no només amb les veus i les paraules arxivades, sinó amb aquelles que volem recollir i rebre.

Absorption and pharmacokinetics of grapefruit flavanones in beagles

The present study evaluated the pharmacokinetics of three different grapefruit flavanone forms in dog plasma and demonstrated their absorption after an oral intake of a grapefruit extract; pharmacokinetic parameters of these forms were also determined. Ten healthy beagles were administered 70 mg citrus flavonoids as a grapefruit extract contained in capsules, while two additional dogs were used as controls and given an excipient. The grapefruit flavanone naringin, along with its metabolites naringenin and naringenin glucuronide, was detected in dog plasma. Blood samples were collected between 0 and 24 h after administration of the extract. Naringin reached its maximun plasma concentration at around 80 min, whereas naringenin and naringenin glucuronide reached their maximun plasma concentrations at around 20 and 30 min, respectively. Maximum plasma concentrations of naringin, naringenin and naringenin glucuronide (medians and ranges) were 0·24 (0·05 2·08), 0·021 (0·001 0·3) and 0·09 (0·034 0·12) mmol/l, respectively. The areas under the curves were 23·16 l (14·04 70·62) min £ mmol/for nariningin, 1·78 (0·09 4·95) min £ mmol/l for naringenin and 22·5 (2·74 99·23) min £ mmol/l for naringenin glucuronide. The median and range values for mean residence time were 3·3 (1·5 9·3), 2·8 (0·8 11·2) and 8·0 (2·3 13·1) h for naringin, naringenin and naringenin glucuronide, respectively. The results of the present study demonstrate the absorption of grapefruit flavanones via the presence of their metabolites in plasma, thus making an important contribution to the field since the biological activities ascribed to these compounds rely on their specific forms of absorption.

Absorption and pharmacokinetics of green tea catechins in beagles

The present study evaluates for the first time in dogs, the kinetics of green tea catechins and their metabolic forms in plasma and urine. Ten beagles were administered 173 mg (12·35 mg/kg body weight) of catechins as a green tea extract, in capsules. Blood samples were collected during 24 h after intake and urine samples were collected during the following periods of time: 02, 26, 68 and 824 h. Two catechins with a galloyl moiety and three conjugated metabolites were detected in plasma. Most of the detected forms in plasma reached their maximum plasma concentration (Cmax) at around 1 h. Median Cmax for (2)-epigallocatechin-3-gallate (EGCG), (2)-epicatechin-3-gallate (ECG), (2)-epigallocatechin glucuronide (EGCglucuronide), (2)-epicatechin glucuronide (EC-glucuronide), (2)-epicatechin sulphate (EC sulphate) were 0·3 (range 0·11·9), 0·1 (range 00·4), 0·8 (range 0·23·9), 0·2 (range 0·1 1·7) and 1 (range 0·33·4) mmol/l, respectively. The areas under the plasma concentration v. time curves (AUC0!24) were 427 (range 1021185) mmol/l £ min for EGC-glucuronide, 112 (range 53919) mmol/l £ min for EC-sulphate, 71 (range 26306) mmol/l £ min for EGCG, 40 (range 12258) mmol/l £ min for EC-glucuronide and 14 (range 0·1124) mmol/l £ min for ECG. The values of mean residence time (MRT0!24) were 5 (range 216), 2 (range 111), 10 (range 213), 3 (range 216) and 2·4 (range 118) h for EGCG, ECG, EGC-glucuronide, EC-glucuronide and EC sulphate, respectively. In urine, catechins were present as conjugated forms, suggesting bile excretion of EGCG and ECG. Green tea catechins are absorbed following an oral administration and EGC-glucuronide is the metabolic form that remains in the organism for a longer period of time, suggesting that this compound could suffer an enterohepatic cycle.

Biblio-MetReS: A bibliometric network reconstruction application and server

Background: Reconstruction of genes and/or protein networks from automated analysis of the literature is one of the current targets of text mining in biomedical research. Some user-friendly tools already perform this analysis on precompiled databases of abstracts of scientific papers. Other tools allow expert users to elaborate and analyze the full content of a corpus of scientific documents. However, to our knowledge, no user friendly tool that simultaneously analyzes the latest set of scientific documents available on line and reconstructs the set of genes referenced in those documents is available. Results: This article presents such a tool, Biblio-MetReS, and compares its functioning and results to those of other user-friendly applications (iHOP, STRING) that are widely used. Under similar conditions, Biblio-MetReS creates networks that are comparable to those of other user friendly tools. Furthermore, analysis of full text documents provides more complete reconstructions than those that result from using only the abstract of the document. Conclusions: Literature-based automated network reconstruction is still far from providing complete reconstructions of molecular networks. However, its value as an auxiliary tool is high and it will increase as standards for reporting biological entities and relationships become more widely accepted and enforced. Biblio- MetReS is an application that can be downloaded from http://metres.udl.cat/. It provides an easy to use environment for researchers to reconstruct their networks of interest from an always up to date set of scientific documents.

T-Coffee: a web server for the multiple sequence alignment of protein and RNA sequences using structural information and homology extension

This article introduces a new interface for T-Coffee, a consistency-based multiple sequence alignment program. This interface provides an easy and intuitive access to the most popular functionality of the package. These include the default T-Coffee mode for protein and nucleic acid sequences, the M-Coffee mode that allows combining the output of any other aligners, and template-based modes of T-Coffee that deliver high accuracy alignments while using structural or homology derived templates. These three available template modes are Expresso for the alignment of protein with a known 3D-Structure, R-Coffee to align RNA sequences with conserved secondary structures and PSI-Coffee to accurately align distantly related sequences using homology extension. The new server benefits from recent improvements of the T-Coffee algorithm and can align up to 150 sequences as long as 10 000 residues and is available from both http://www.tcoffee.org and its main mirror http://tcoffee.crg.cat.

Optimal capital structure: a trade-off model and its empirical testing

In the present research we have set forth a new, simple, Trade-Off model that would allow us to calculate how much debt and, by default, how much equity a company should have, using easily available information and calculating the cost of debt dynamically on the basis of the effect that the capital structure of the company has on the risk of bankruptcy; in an attempt to answer this question. The proposed model has been applied to the companies that make up the Dow Jones Industrial Average (DJIA) in 2007. We have used consolidated financial data from 1996 to 2006, published by Bloomberg. We have used simplex optimization method to find the debt level that maximizes firm value. Then, we compare the estimated debt with real debt of companies using statistical nonparametric Mann-Whitney. The results indicate that 63% of companies do not show a statistically significant difference between the real and the estimated debt.

The persistence of return on assets: differences between industries and differences between firms

This study offers a statistical analysis of the persistence of annual profits across a sample of firms from different European Union (EU) countries. To this end, a Bayesian dynamic model has been used which enables the annual behaviour of those profits to be broken down into a permanent structural component on the one hand and a transitory component on the other, while also distinguishing between general effects affecting the industry as a whole to which each firm belongs and specific effects affecting each firm in particular. This break down enables the relative importance of those fundamental components to be evaluated. The data analysed come from a sample of 23,293 firms in EU countries selected from the AMADEUS data-base. The period analysed ran from 1999 to 2007 and 21 sectors were analysed, chosen in such a way that there was a sufficiently large number of firms in each country*sector combination for the industry effects to be estimated accurately enough for meaningful comparisons to be made by sector and country. The analysis has been conducted by sector and by country from a Bayesian perspective, thus making the study more flexible and realistic since the estimates obtained do not depend on asymptotic results. In general terms, the study finds that, although the industry effects are significant, more important are the specific effects. That importance varies depending on the sector or the country in which the firm carries out its activity. The influence of firm effects accounts for more than 90% of total variation and display a significantly lower degree of persistence, with adjustment speeds oscillating around 51.1%. However, this pattern is not homogeneous but depends on the sector and country analysed. Industry effects have a more marginal importance, being significantly more persistent, with adjustment speeds oscillating around 10% with this degree of persistence being more homogeneous at both country and sector levels.

Ownership change and banking efficiency in the new EU members

The aim of this study is to analyze how European integration and, especially, changes in ownership, has affected banking efficiency in Central and Eastern European countries which have recently experimented this process more intensely. Using a stochastic frontier approach (SFA) applied to panel data, we have estimated bank efficiency levels in a sample of 189 banks from 12 countries during the period 2000 to 2008 and we have analyzed the influence of some bank characteristics on these efficiency levels. The results show that European integration has significantly improved the cost efficiency of banks in these countries but profit efficiency has significantly decreased. We have found very small differences between different ownership types and only a very small impact of foreign ownership on cost efficiency, showing that the entry of foreign ownership is not enough to explain the significant variations in banking efficiency after the accession.
