A qui li dic? : la detecció de l’abús sexual infantil i el traspàs d’informació entre professionals

Aquest treball s'estructura en una primera part de fonamentació teòrica. El procediment que s'ha seguit ha estat la recerca bibliogràfica. Es basa en els aspectes tècnics a tenir en compte per la detecció de l' Abusos Sexuals Infantils (ASI), la ubicació dels Serveis Bàsics d'Atenció Social (SBAS) dins el sistema català de serveis socials, el marc jurídic dels drets i de la protecció a la infància i l'adolescència així com de qüestions relatives al tractament de dades, de la confidencialitat de les informacions de què disposem els/les professionals, l'obligació de secret, complementat amb la deontologia professional, que ens pot orientar a l'hora de prendre les decisions més adequades a la nostra praxi. La segona part del treball és empírica. El procediment ha estat portar a terme un grup de reflexió ètica amb professionals del Consorci de Benestar Social del Pla de l'Estany-Banyoles. Partint de casos pràctics de sospita d'ASI, les persones participants han concretat els principals problemes (alguns dels quals relacionats amb l'ètica aplicada) davant els quals s'han trobat a la fase de detecció/intervenció. Les aportacions extretes de les diferents sessions en les quals es van treballar part dels objectius d'aquesta recerca ens permeten concretar la realitat i una primera deliberació sobre quina podria ser la bona pràctica general. La tercera part utilitza la fonamentació teòrica i els material del treball de camp per presentar la reflexió final que pretén donar resposta als objectius plantejats en aquesta recerca

Selective toxicity of the general anesthetic propofol for GABAergic neurons in rat brain cell cultures.

The intravenous, short-acting general anesthetic propofol was applied to three-dimensional (aggregating) cell cultures of fetal rat telencephalon. Both the clinically used formulation (Disoprivan, ICI Pharmaceuticals, Cheshire, England) and the pure form (2,6-diisopropylphenol) were tested at two different periods of brain development: immature brain cell cultures prior to synaptogenesis and at the time of intense synapses and myelin formation. At both time periods and for clinically relevant concentrations and time of exposure (i.e., concentrations > or = 2.0 micrograms/ml for 8 hr), propofol caused a significant decrease of glutamic acid decarboxylase activity. This effect persisted after removal of the drug, suggesting irreversible structural changes in GABAergic neurons. The gamma-aminobutyric acid type A (GABAA) blocking agents bicuculline and picrotoxin partially attenuated the neurotoxic effect of propofol in cultures treated at the more mature phase of development. This protective effect was not observed in the immature brain cells. The present data suggest that propofol may cause irreversible lesions to GABAergic neurons when given at a critical phase of brain development. In contrast, glial cells and myelin appeared resistant even to high doses of propofol.

The relation of body mass index and abdominal adiposity with dyslipidemia in 27 general populations of the WHO MONICA Project.

The association between adiposity measures and dyslipidemia has seldom been assessed in a multipopulational setting. 27 populations from Europe, Australia, New Zealand and Canada (WHO MONICA project) using health surveys conducted between 1990 and 1997 in adults aged 35-64 years (n = 40,480). Dyslipidemia was defined as the total/HDL cholesterol ratio >6 (men) and >5 (women). Overall prevalence of dyslipidemia was 25% in men and 23% in women. Logistic regression showed that dyslipidemia was strongly associated with body mass index (BMI) in men and with waist circumference (WC) in women, after adjusting for region, age and smoking. Among normal-weight men and women (BMI<25 kg/m(2)), an increase in the odds for being dyslipidemic was observed between lowest and highest WC quartiles (OR = 3.6, p < 0.001). Among obese men (BMI ≥ 30), the corresponding increase was smaller (OR = 1.2, p = 0.036). A similar weakening was observed among women. Classification tree analysis was performed to assign subjects into classes of risk for dyslipidemia. BMI thresholds (25.4 and 29.2 kg/m(2)) in men and WC thresholds (81.7 and 92.6 cm) in women came out at first stages. High WC (>84.8 cm) in normal-weight men, menopause in women and regular smoking further defined subgroups at increased risk. standard categories of BMI and WC, or their combinations, do not lead to optimal risk stratification for dyslipidemia in middle-age adults. Sex-specific adaptations are necessary, in particular by taking into account abdominal obesity in normal-weight men, post-menopausal age in women and regular smoking in both sexes.

La matèria de Bretanya a Catalunya, Escòcia i Anglaterra

Aquest projecte examina la literatura artúrica medieval catalana occitana, anglesa i escocesa. Un estudi comparatiu a partir de les fonts franceses originals palesa les seves diferents adaptacions i traduccions als models culturals autòctons, mostrant les característiques comunes i les diferenciadores dins del marc literari europeu. S’argumentà que els contexts històrics i intel•lectuals influïren en la composició d’aquestes obres de manera que la llegenda artúrica respon a les inquietuds polítiques i socials contemporànies. Les tensions interterritorials i internacionals existents a la Corona d'Aragó condicionaren la composició de les obres com és el cas de La faula de Guillem de Torroella, que pot ser interpretada en clau dels enfrontaments entre Pere III i Jaume III de Mallorca i el paper que hi podria haver jugat una intervenció francesa en favor dels illencs. Per la seva banda, el Roman de Fergus utilitza la figura artúrica per enaltir la reialesa normanda escocesa i excloure els habitants d'origen celta de les esferes de poder. Des del punt de vista de la traducció i els estudis vernaculars, s’examinà com la Matèria de Bretanya contribuí a l’establiment i promoció d’una cultura nacional escrita en llengua pròpia davant de la cultura llatina hegemònica. Les prestigioses fonts franceses de les quals es deriven els texts catalans, francesos i anglesos permeteren de manera simbòlica que les llengües d'aquests països adquiriren el mateix prestigi que el francès, tot ajudant a la promoció de les llengües vernaculars en ambients cultes.

Prevalença de factors de risc cardiovascular i qualitat de vida en pacients amb trastorn mental sever

L’objectiu és descriure els factors de RCV i variables relacionades amb la qualitat de vida de pacients amb TMS. Estudi transversal on s’analitzen variables clíniques, antropomètriques, anàlitiques i d’estils de vida en 212 pacients.

Identification of naturally processed hepatitis C virus-derived major histocompatibility complex class I ligands.

Fine mapping of human cytotoxic T lymphocyte (CTL) responses against hepatitis C virus (HCV) is based on external loading of target cells with synthetic peptides which are either derived from prediction algorithms or from overlapping peptide libraries. These strategies do not address putative host and viral mechanisms which may alter processing as well as presentation of CTL epitopes. Therefore, the aim of this proof-of-concept study was to identify naturally processed HCV-derived major histocompatibility complex (MHC) class I ligands. To this end, continuous human cell lines were engineered to inducibly express HCV proteins and to constitutively express high levels of functional HLA-A2. These cell lines were recognized in an HLA-A2-restricted manner by HCV-specific CTLs. Ligands eluted from HLA-A2 molecules isolated from large-scale cultures of these cell lines were separated by high performance liquid chromatography and further analyzed by electrospray ionization quadrupole time of flight mass spectrometry (MS)/tandem MS. These analyses allowed the identification of two HLA-A2-restricted epitopes derived from HCV nonstructural proteins (NS) 3 and 5B (NS3₁₄₀₆₋₁₄₁₅ and NS5B₂₅₉₄₋₂₆₀₂). In conclusion, we describe a general strategy that may be useful to investigate HCV pathogenesis and may contribute to the development of preventive and therapeutic vaccines in the future.

The role of moral values in the economic analysis of crime: A general equilibrium approach

In this paper, we develop a general equilibrium model of crime and show thatlaw enforcement has different roles depending on the equilibrium characterization and the value of social norms. When an economy has a unique stable equilibrium where a fraction of the population is productive and the remaining predates, the government can choose an optimal law enforcement policy to maximize a welfare function evaluated at the steady state. If such steady state is not unique, law enforcement is still relevant but in a completely different way because the steady state that prevails depends on the initial proportions of productive and predator individuals in the economy. The relative importance of these proportions can be changed through law enforcement policy.

Associationism and electoral participation: A multilevel study of 2000 Spanish general election

This work presents an application of the multilevel analysis techniques tothe study of the abstention in the 2000 Spanish general election. Theinterest of the study is both, substantive and methodological. From thesubstantive point of view the article intends to explain the causes ofabstention and analyze the impact of associationism on it. From themethodological point of view it is intended to analyze the interaction betweenindividual and context with a modelisation that takes into account thehierarchical structure of data. The multilevel study of this paper validatesthe one level results obtained in previous analysis of the abstention andshows that only a fraction of the differences in abstention are explained bythe individual characteristics of the electors. Another important fraction ofthese differences is due to the political and social characteristics of thecontext. Relating to associationism, the data suggest that individualparticipation in associations decrease the probability of abstention. However,better indicators are needed in order to catch more properly the effect ofassociationism in electoral behaviour.

La réhabilitation psychosociale a l'aube du XXIème siècle. I: Principes, population cible et pathologie en cause

The relatively recent development of the psychosocial rehabilitation has its origins mainly in the progress of modern psychopharmacology, the assertion of the rights of the patients and the result of the studies showing that the evolution of persons suffering from severe and persistent mental illnesses can prove to be positive in many cases. In spite of the heterogeneity of the experiences and of the theoretical references, the core principles of the psychosocial rehabilitation imposed themselves. These principles can be classified according to three levels, that of relational ethics, that of the method of intervention and that of the institutional device. A recent study showed that 2.4@1000 of the general adult population of the Canton of Vaud live in sociotherapeutic and rehabilitation accommodations. In this sample, there is a important percentage of relatively young persons (55.3% are under 40). In institutional accommodation there is a majority of patients suffering from major personality disorders and addiction (40.6%), followed by psychotic disorders (37.2%), persistent mood disorders (12.3%), neurotic disorders (6.6%) and psycho-organic disorders (3.3%). In home based rehabilitation, the ratio of patients with psychotic disorders is more important (53.1%). This difference would indicate that people with schizophrenia would have a better social outcome than personality disorders with addiction

Notes for a new guide to Keynes (I): Wages, aggregate demand, and employment

I revisit the General Theory's discussion of the role of wages inemployment determination through the lens of the New Keynesianmodel. The analysis points to the key role played by the monetarypolicy rule in shaping the link between wages and employment, andin determining the welfare impact of enhanced wage flexibility. I showthat the latter is not always welfare improving.

Credit constraints in general equilibrium: Experimental results

Our work attempts to investigate the influence of credit tightness orexpansion on activity and relative prices in a multimarket set-up. We report on somedouble- auction, two-market experiments where subjects had to satisfy an inequalityinvolving the use of credit. The experiments display two regimes, characterizedby high and low credit availability. The critical value of credit at the commonboundary of the two regimes has a compelling interpretation as the maximal credituse at the Arrow-Debreu equilibrium of the abstract economy naturally associatedto our experimental environment. Our main results are that changes in theavailability of credit: (a): have minor and unsystematic effects on quantitiesand relative prices in the high-credit regime, (b): have substantial effects, bothon quantities and relative prices, in the low-credit regime.

A general class of adaptative strategies

We exhibit and characterize an entire class of simple adaptive strategies,in the repeated play of a game, having the Hannan-consistency property: In the long-run, the player is guaranteed an average payoff as large as the best-reply payoff to the empirical distribution of play of the otherplayers; i.e., there is no "regret." Smooth fictitious play (Fudenberg and Levine [1995]) and regret-matching (Hart and Mas-Colell [1998]) areparticular cases. The motivation and application of this work come from the study of procedures whose empirical distribution of play is, in thelong-run, (almost) a correlated equilibrium. The basic tool for the analysis is a generalization of Blackwell's [1956a] approachability strategy for games with vector payoffs.
