Filó d'Alexandria i el seu De opificio mundi (LIII-LXI): tot copsant les claus de la misogínia grega i occidental en un text jueu platonitzant.

L'objectiu d'aquest article és mostrar la secular tradició misògina occidental des dels seus orígens a Grècia tot analitzant un text de l'intèrpret al·legoric de la Bíblia Filó d'Alexandria, el De opificio mundi, al qual aplica una lectura fortament platonitzant. L'anàlisi acurada dels capítols dedicats a la creació divina de la dona i les seves conseqüències mostra fins a quin punt no és possible entendre aquest text sense tenir en compte una tradició filosòfica grega ja aleshores secular.

Grècia i amor platònic a Maurice d'E. M. Forster, o la grandesa i els límits de l'Antiguitat com a inspiració.

L'objectiu d¿aquest article és mostrar com, malgrat la idealització evident de Grècia i l'amor platònic en diferents autors de l'Anglaterra Victoriano-Eduardina, ambdós tenen els seus límits. Per explicar-ho, doncs, l'autor presenta una anàlisi minuciosa del text anglès i, alhora, fa constants referències al textos grecs implícits, com ara el Simposi i el Fedre de Plató i tal vegada fins i tot l'Eròtic de Plutarc en cerca d'una tradició clàssica que és cabdal per entendre l'Anglaterra de principis del segle XX.

La fortuna di Luciano nel Rinascimento : il volgarizzamento del manoscritto Vaticano Chigiano L.VI.215 : edizione critica dei volgarizzamenti delle "Storie vere"

Résumé II lavoro verte sui volgarizzamenti quattro-cinquecenteschi di Luciano di Samosata, importante capitolo nella fortuna dell'autore greco, che diede l'avvio a quel vasto fenomeno chiamato "lucianesimo", esteso in Europa fino al XIX sec. In particolare fornisco l'edizione critica e commentata delle Storie vere volgarizzate, contenute nella prima, assai ampia (41 opuscoli), e per molto tempo unica, silloge lucianea in volgare, che ho datato a poco prima del 1480. Essa ci è giunta tramite un unico manoscritto, il Vaticano Chigiano L.VI.215, confezionato a Ferrara per Ercole I d'Este, nonché in almeno otto edizioni veneziane apparse fra il 1525 e il 1551. La princeps, da cui dipendono in vario modo tutte le edizioni successive, è pubblicata da Niccolò Zoppino. I1 ms. e le prime due edizioni (1525; 1527 Bindoni e Pasini) tacciono il nome del traduttore, che compare solo nell'edizione del 1529 (Zoppino): Niccolò Leoniceno (1428-1524), medico umanista e valente grecista, attivo a Ferrara dal 1464 al 1524, studioso e traduttore di Ippocrate e Galeno, editore di Aristotele e volgarizzatore di storici per Ercole d'Este. L'edizione ha richiesto uno studio preliminare sulle numerose traduzioni in latino e in volgare di Luciano, per valutare meglio le modalità della sua fortuna umanistica. Confrontando ms. e stampe, per le Storie vere si hanno due volgarizzamenti totalmente diversi, fin dal titolo: La vera historia nel ms., Le vere narrazioni nelle cinquecentine. Ma per l'ultimo quarto di testo, ms. e stampe in sostanza coincidono. La collazione ha coinvolto anche il testo greco (con gli apparati delle edizioni critiche) e la versione latina dell'umanista umbro Lilio Tifernate (1417/18-1486) risalente al 1439-43 ca., intitolata De veris narrationibus, di cui si hanno almeno tre redazioni d'autore; una quarta è invece dovuta probabilmente a Benedetto Bordon, che la inserì nella sua silloge latina di Luciano del 1494. Ho cosa stabilito che il volgarizzamento del ms. Chigiano, La vera historia, è stato eseguito direttamente dal greco, fatto eccezionale nel panorama delle traduzioni umanistiche, mentre quello a stampa, Le vere narrazioni, deriva dalla redazione Bordon del De veris narrationibus. La diversità dei titoli dipende dalle varianti dei codici greci utilizzati dai traduttori: il Vat. gr. 1323, o una sua copia, è utilizzato sia dal volgarizzatore del Chigiano, sia da Bordon, indipendentemente l'uno dall'altro; il Marc. gr. 434, o una sua copia, dal Tifernate. Il titolo latino mantenuto da Bordon risale al Tifernate. Per quanto riguarda l'attribuzione dei due volgarizzamenti, come già per altri due testi della silloge da me studiati (Lucio 01 Asino e Timone), anche per La vera historia del Chigiano è accettabile il nome di Niccolò Leoniceno, poiché: 1) essa è tradotta direttamente dal greco, correttamente e con buona resa in volgare, 2) Paolo Giovio -che conobbe di persona il Leoniceno -, negli Elogia veris clarorum virorum imaginibus apposita ricorda che i volgarizzamenti di Luciano e di Dione eseguiti dal Leoniceno piacquero molto ad Ercole d'Este, 3) nessuno nella prima metà del sec. XVI rivendica, per sé o per un suo maestro, il volgarizzamento di Luciano. Le vere narrazioni a stampa, tradotte dal latino del Bordon, dopo il 1494 e prima del 1525, per la parte che diverge dalla Vera historia rimangono invece anonime. Dato che si tratta di due volgarizzamenti distinti, ho allestito l'edizione a fronte dei due testi fin dove essi divergono, seguendo per l'uno il ms., per l'altro la princeps; per la parte finale, in cui confluiscono, mi baso invece sul manoscritto e relego in apparato le varianti più vistose della princeps (non è emerso un chiaro rapporto di dipendenza fra i due testimoni). Oltre all'apparato critico con le lezioni rifiutate, fornisco un commento con la giustificazione delle scelte e il confronto con i corrispondenti passi greci e latini.

Prevalence and factors of intensive care unit conflicts: the conflicus study.

RATIONALE: Many sources of conflict exist in intensive care units (ICUs). Few studies recorded the prevalence, characteristics, and risk factors for conflicts in ICUs. OBJECTIVES: To record the prevalence, characteristics, and risk factors for conflicts in ICUs. METHODS: One-day cross-sectional survey of ICU clinicians. Data on perceived conflicts in the week before the survey day were obtained from 7,498 ICU staff members (323 ICUs in 24 countries). MEASUREMENTS AND MAIN RESULTS: Conflicts were perceived by 5,268 (71.6%) respondents. Nurse-physician conflicts were the most common (32.6%), followed by conflicts among nurses (27.3%) and staff-relative conflicts (26.6%). The most common conflict-causing behaviors were personal animosity, mistrust, and communication gaps. During end-of-life care, the main sources of perceived conflict were lack of psychological support, absence of staff meetings, and problems with the decision-making process. Conflicts perceived as severe were reported by 3,974 (53%) respondents. Job strain was significantly associated with perceiving conflicts and with greater severity of perceived conflicts. Multivariate analysis identified 15 factors associated with perceived conflicts, of which 6 were potential targets for future intervention: staff working more than 40 h/wk, more than 15 ICU beds, caring for dying patients or providing pre- and postmortem care within the last week, symptom control not ensured jointly by physicians and nurses, and no routine unit-level meetings. CONCLUSIONS: Over 70% of ICU workers reported perceived conflicts, which were often considered severe and were significantly associated with job strain. Workload, inadequate communication, and end-of-life care emerged as important potential targets for improvement.

En torno a los efectos de la edad en el aprendizaje escolar de una lengua extrangera

The purpose of this article is to treat a currently much debated issue, the effects of age on second language learning. To do so, we contrast data collected by our research team from over one thousand seven hundred young and adult learners with four popular beliefs or generalizations, which, while deeply rooted in this society, are not always corroborated by our data.Two of these generalizations about Second Language Acquisition (languages spoken in the social context) seem to be widely accepted: a) older children, adolescents and adults are quicker and more efficient at the first stages of learning than are younger learners; b) in a natural context children with an early start are more liable to attain higher levels of proficiency. However, in the context of Foreign Language Acquisition, the context in which we collect the data, this second generalization is difficult to verify due to the low number of instructional hours (a maximum of some 800 hours) and the lower levels of language exposure time provided. The design of our research project has allowed us to study differences observed with respect to the age of onset (ranging from 2 to 18+), but in this article we focus on students who began English instruction at the age of 8 (LOGSE Educational System) and those who began at the age of 11 (EGB). We have collected data from both groups after a period of 200 (Time 1) and 416 instructional hours (Time 2), and we are currently collecting data after a period of 726 instructional hours (Time 3). We have designed and administered a variety of tests: tests on English production and reception, both oral and written, and within both academic and communicative oriented approaches, on the learners' L1 (Spanish and Catalan), as well as a questionnaire eliciting personal and sociolinguistic information. The questions we address and the relevant empirical evidence are as follows: 1. "For young children, learning languages is a game. They enjoy it more than adults."Our data demonstrate that the situation is not quite so. Firstly, both at the levels of Primary and Secondary education (ranging from 70.5% in 11-year-olds to 89% in 14-year-olds) students have a positive attitude towards learning English. Secondly, there is a difference between the two groups with respect to the factors they cite as responsible for their motivation to learn English: the younger students cite intrinsic factors, such as the games they play, the methodology used and the teacher, whereas the older students cite extrinsic factors, such as the role of their knowledge of English in the achievement of their future professional goals. 2 ."Young children have more resources to learn languages." Here our data suggest just the opposite. The ability to employ learning strategies (actions or steps used) increases with age. Older learners' strategies are more varied and cognitively more complex. In contrast, younger learners depend more on their interlocutor and external resources and therefore have a lower level of autonomy in their learning. 3. "Young children don't talk much but understand a lot"This third generalization does seem to be confirmed, at least to a certain extent, by our data in relation to the analysis of differences due to the age factor and productive use of the target language. As seen above, the comparably slower progress of the younger learners is confirmed. Our analysis of interpersonal receptive abilities demonstrates as well the advantage of the older learners. Nevertheless, with respect to passive receptive activities (for example, simple recognition of words or sentences) no great differences are observed. Statistical analyses suggest that in this test, in contrast to the others analyzed, the dominance of the subjects' L1s (reflecting a cognitive capacity that grows with age) has no significant influence on the learning process. 4. "The sooner they begin, the better their results will be in written language"This is not either completely confirmed in our research. First of all, we perceive that certain compensatory strategies disappear only with age, but not with the number of instructional hours. Secondly, given an identical number of instructional hours, the older subjects obtain better results. With respect to our analysis of data from subjects of the same age (12 years old) but with a different number of instructional hours (200 and 416 respectively, as they began at the ages of 11 and 8), we observe that those who began earlier excel only in the area of lexical fluency. In conclusion, the superior rate of older learners appears to be due to their higher level of cognitive development, a factor which allows them to benefit more from formal or explicit instruction in the school context. Younger learners, however, do not benefit from the quantity and quality of linguistic exposure typical of a natural acquisition context in which they would be allowed to make use of implicit learning abilities. It seems clear, then, that the initiative in this country to begin foreign language instruction earlier will have positive effects only if it occurs in combination with either higher levels of exposure time to the foreign language, or, alternatively, with its use as the language of instruction in other areas of the curriculum.

Financial crisis: theory and practice

In the last 50 years, we have had approximately 40 events with characteristics related to financial crisis. The most severe crisis was in 1929, when the financial markets plummet and the US gross domestic product decline in more than 30 percent. Recently some years ago, a new crisis developed in the United States, but instantly caused consequences and effects in the rest of the world.This new economic and financial crisis has increased the interest and motivation for the academic community, professors and researchers, to understand the causes and effects of the crisis, to learn from it. This is the one of the main reasons for the compilation of this book, which begins with a meeting of a group of IAFI researchers from the University of Barcelona, where researchers form Mexico and Spain, explain causes and consequences of the crisis of 2007.For that reason, we believed this set of chapters related to methodologies, applications and theories, would conveniently explained the characteristics and events of the past and future financial crisisThis book consists in 3 main sections, the first one called "State of the Art and current situation", the second named "Econometric applications to estimate crisis time periods" , and the third one "Solutions to diminish the effects of the crisis". The first section explains the current point of view of many research papers related to financial crisis, it has 2 chapters. In the first one, it describe and analyzes the models that historically have been used to explain financial crisis, furthermore, it proposes to used alternative methodologies such as Fuzzy Cognitive Maps. On the other hand , Chapter 2 , explains the characteristics and details of the 2007 crisis from the US perspective and its comparison to 1929 crisis, presenting some effects in Mexico and Latin America.The second section presents two econometric applications to estimate possible crisis periods. For this matter, Chapter 3, studies 3 Latin-American countries: Argentina, Brazil and Peru in the 1994 crisis and estimates the multifractal characteristics to identify financial and economic distress.Chapter 4 explains the crisis situations in Argentina (2001), Mexico (1994) and the recent one in the United States (2007) and its effects in other countries through a financial series methodology related to the stock market.The last section shows an alternative to prevent the effects of the crisis. The first chapter explains the financial stability effects through the financial system regulation and some globalization standards. Chapter 6, study the benefits of the Investor activism and a way to protect personal and national wealth to face the financial crisis risks.

Fabricants, comerciants i banquers. Les estructures comercials de la indústria cotonera catalana en el mercat español (1840-1936)

Aquesta tesi analitza la integració vertical entre fabricació, comercialització i finançament a la indústria catalana del període 1840-1936. L¿evidència obtinguda de les fonts arxivístiques confirma la visió tradicional quant a la descripció dels fets, però ofereix una interpretació alternativa, més optimista, de les causes i de les conseqüències. Els fabricants s¿implicaren en la comercialització perquè ells eren els coordinadors entre oferta i demanda (no com en el cas britànic, on ho eren els comerciants), i per tant havien de tenir un peu a cada banda. A més, els fabricants eren els més ben situats per a ser uns banquers eficients dels seus clients.

Integración económica y localización industrial. Cataluña, la fábrica de España: ¿cuándo y por qué?

En este artículo se analizan los determinantes de la localización de la actividad industrial en España durante la segunda mitad del siglo XIX. El objetivo es estudiar la existencia de cambios en los factores explicativos de la localización, con el fin de identificar los efectos de la integración económica sobre la geografía industrial española. Para hacerlo, en primer lugar se analiza la literatura histórica existente. En segundo lugar, se describen las teorías que explican la localización de l'actividad. En tercer lugar, se realiza un análisis empírico de la localización y la concentración de la industria española al siglo XIX. A continuación, se propone un estudio econométrico de los determinantes de la localización industrial en dos cortes temporales, 1856 y 1893. Los resultados son consistentes con las teorías del comercio. Durante el decurso de la segunda mitad del siglo XIX, España paso a ser una economía integrada, la movilidad del trabajo y del capital se vio favorecida y como resultado, las diferencias relativas en las dotaciones de factores perdieron importancia en la explicación de las pautas de especialización industrial. Por el contrario, la integración económica favoreció la significación relativa de las economías de escala o de la proximidad a los mercados como elementos explicativos de la localización de la industria, favoreciendo, de esta manera, la aglomeración de la actividad industrial

Networks of people in specialty production: family firms in the iron and steel Wire industries in Spain (1870-2000)

Capital intensive industries in specialized niches of production have constituted solid ground for family firms in Spain , as evidenced by the experience of the iron and steel wire industries between 1870 and 2000. The embeddedness of these firms in their local and regional environments have allowed the creation of networks that, together with favourable institutional conditions, significantly explain the dominance of family entrepreneurship in iron and steel wire manufacturing in Spain, until the end of the 20 th century. Dominance of family firms at the regional level has not been not an obstacle for innovation in wire manufacturing in Spain, which has taken place even when institutional conditions blocked innovation and traditional networking. Therefore, economic theories about the difficulties dynastic family firms may have to perform appropriately in science-based industries must be questioned

The Role of Interleukin-2 in Memory CD8 Cell Differentiation

The current literature on the role of interleukin (IL)-2 in memory CD8(+) T-cell differentiation indicates a significant contribution of IL-2 during primary and also secondary expansion of CD8(+) T cells. IL-2 seems to be responsible for optimal expansion and generation of effector functions following primary antigenic challenge. As the magnitude of T-cell expansion determines the numbers of memory CD8(+) T cells surviving after pathogen elimination, these events influence memory cell generation. Moreover, during the contraction phase of an immune response where most antigen-specific CD8(+) T cells disappear by apoptosis, IL-2 signals are able to rescue CD8(+) T cells from cell death and provide a durable increase in memory CD8(+) T-cell counts. At the memory stage, CD8(+) T-cell frequencies can be boosted by administration of exogenous IL-2. Significantly, only CD8(+) T cells that have received IL-2 signals during initial priming are able to mediate efficient secondary expansion following renewed antigenic challenge. Thus, IL-2 signals during different phases of an immune response are key in optimizing CD8(+) T-cell functions, thereby affecting both primary and secondary responses of these T cells.

All assignment games with the same core have the same nucleolus

There exist coalitional games with transferable utility which have the same core but different nucleoli. We show that this cannot happen in the case of assignment games. Whenever two assignment games have the same core, their nucleoli also coincide. To show this, we prove that the nucleolus of an assignment game coincides with that of its buyer-seller exact representative

Multi-sided Böhm-Bawerk assignment markets: the nucleolus and the core-center

En aquest treball mostrem que, a diferència del cas bilateral, per als mercats multilaterals d'assignació coneguts amb el nom de Böhm-Bawerk assignment games, el nucleolus i el core-center, i. e. el centre de masses del core, no coincideixen en general. Per demostrar-ho provem que donant un m-sided Böhm-Bawerk assignment game les dues solucions anteriors poden obtenir-se respectivament del nucleolus i el core-center d'un joc convex definit en el conjunt format pels m sectors. Encara més, provem que per calcular el nucleolus d'aquest últim joc només les coalicions formades per un jugador o m-1 jugadors són importants. Aquests resultats simplifiquen el càlcul del nucleolus d'un multi-sided ¿¿ohm-Bawerk assignment market amb un número molt elevat d'agents.

Bcl10 controls TCR- and FcgammaR-induced actin polymerization.

Bcl10 plays an essential role in the adaptive immune response, because Bcl10-deficient lymphocytes show impaired Ag receptor-induced NF-kappaB activation and cytokine production. Bcl10 is a phosphoprotein, but the physiological relevance of this posttranslational modification remains poorly defined. In this study, we report that Bcl10 is rapidly phosphorylated upon activation of human T cells by PMA/ionomycin- or anti-CD3 treatment, and identify Ser(138) as a key residue necessary for Bcl10 phosphorylation. We also show that a phosphorylation-deficient Ser(138)/Ala mutant specifically inhibits TCR-induced actin polymerization yet does not affect NF-kappaB activation. Moreover, silencing of Bcl10, but not of caspase recruitment domain-containing MAGUK protein-1 (Carma1) induces a clear defect in TCR-induced F-actin formation, cell spreading, and conjugate formation. Remarkably, Bcl10 silencing also impairs FcgammaR-induced actin polymerization and phagocytosis in human monocytes. These results point to a key role of Bcl10 in F-actin-dependent immune responses of T cells and monocytes/macrophages.

Epac contributes to cardiac hypertrophy and amyloidosis induced by radiotherapy but not fibrosis.

BACKGROUND: Cardiac toxicity is a side-effect of anti-cancer treatment including radiotherapy and this translational study was initiated to characterize radiation-induced cardiac side effects in a population of breast cancer patients and in experimental models in order to identify novel therapeutic target. METHODS: The size of the heart was evaluated in CO-HO-RT patients by measuring the Cardiac-Contact-Distance before and after radiotherapy (48months of follow-up). In parallel, fibrogenic signals were studied in a severe case of human radiation-induced pericarditis. Lastly, radiation-induced cardiac damage was studied in mice and in rat neonatal cardiac cardiomyocytes. RESULTS: In patients, time dependent enhancement of the CCD was measured suggesting occurrence of cardiac hypertrophy. In the case of human radiation-induced pericarditis, we measured the activation of fibrogenic (CTGF, RhoA) and remodeling (MMP2) signals. In irradiated mice, we documented decreased contractile function, enlargement of the ventricular cavity and long-term modification of the time constant of decay of Ca(2+) transients. Both hypertrophy and amyloid deposition were correlated with the induction of Epac-1; whereas radiation-induced fibrosis correlated with Rho/CTGF activation. Transactivation studies support Epac contribution in hypertrophy stimulation and showed that radiotherapy and Epac displayed specific and synergistic signals. CONCLUSION: Epac-1 has been identified as a novel regulator of radiation-induced hypertrophy and amyloidosis but not fibrosis in the heart.
