Rigor metodológico e investigación filológica

In recent decades, technological advances have made extensive documentation available to us. But the philologist must be aware of the dangers of poor use of the documentary corpus in order to avoid creating dreaded ghost words. In this paper we recall the main sources of this type of error: folk etymology phenomena among speakers, copyists" errors, transcribers" errors in the interpretation of some abbreviations and graphic variants of the manuscripts, onomastic changes introduced by cartographers" ignorance of linguistic variants, gaps in the dating of some documents, confusion in the processes of lemmatization and the evaluation of texts... All these sources of error contribute, to a greater or lesser degree, to the distortion or to the masking of the data on which the research of philologists is based. Hence the importance of philological rigour in the transmission and study of ancient texts.

Leverage and beliefs: Personal experience and risk taking in margin lending

What determines risk-bearing capacity and the amount of leverage in financial markets? Thispaper uses unique micro-data on collateralized lending contracts during a period of financialdistress to address this question. An investor syndicate speculating in English stocks wentbankrupt in 1772. Using hand-collected information from Dutch notarial archives, we examinechanges in lenders' behavior following exposure to potential (but not actual) losses. Before thedistress episode, financiers that lent to the ill-fated syndicate were indistinguishable from therest. Afterwards, they behaved differently: they lent with much higher haircuts. Only lendersexposed to the failed syndicate altered their behavior. The differential change is remarkable sincethe distress was public knowledge, and because none of the lenders suffered actual losses ? allfinanciers were repaid in full. Interest rates were also unaffected; the market balanced solelythrough changes in collateral requirements. Our findings are consistent with a heterogeneousbeliefs-interpretation of leverage. They also suggest that individual experience can modify thelevel of leverage in a market quickly.

Plegarias iluminadas: libros de horas conservados en bibliotecas catalanas

A través de este texto, pretendemos dar a conocer los libros de horas iluminados conservados en bibliotecas públicas catalanas. Con este fin, se han analizado un total de quince manuscritos, a nuestro juicio los más interesantes desde el punto de vista artístico, localizados en la Biblioteca de Catalunya, Biblioteca de la Universidad de Barcelona, Archivo Histórico de la Ciudad de Barcelona, Museo Episcopal de Vic, Biblioteca del monasterio de Santa María de Montserrat y Biblioteca del Palacio de Perelada. Los libros de horas se han agrupado de acuerdo con su procedencia geográfica: antiguos reinos peninsulares (Corona de Aragón y de Castilla), Francia, repúblicas italianas, Inglaterra y territorios septentrionales del ducado de Borgoña. Cada uno de estos apartados se organiza en torno a una secuencia cronológica que comienza a fines del siglo XIV y concluye hacia el segundo cuarto del siglo XVI.

Evaluación de un artículo científico

El proceso de revisión y evaluación de manuscritos, conocido como arbitraje científico o peer review, supone actualmente un paso que se considera necesario para la divulgación de los avances científicos de una determinada disciplina. Cuando una revista recibe un artículo, sus editores recurren a revisores expertos que, después de la lectura detenida del manuscrito, evalúan la idoneidad de su publicación, en este trabajo se describe el proceso editorial de un artículo y se muestran los ítems por los cuales se evalúan los artículos.

Statistical Reviewers Improve Reporting in Biomedical Articles: a Randomized Trial.

Background. Although peer review is widely considered to be the most credible way of selecting manuscripts and improving the quality of accepted papers in scientific journals, there is little evidence to support its use. Our aim was to estimate the effects on manuscript quality of either adding a statistical peer reviewer or suggesting the use of checklists such as CONSORT or STARD to clinical reviewers or both. Methodology and Principal Findings. Interventions were defined as 1) the addition of a statistical reviewer to the clinical peer review process, and 2) suggesting reporting guidelines to reviewers; with"no statistical expert" and"no checklist" as controls. The two interventions were crossed in a 262 balanced factorial design including original research articles consecutively selected, between May 2004 and March 2005, by the Medicina Clinica (Barc) editorial committee. We randomized manuscripts to minimize differences in terms of baseline quality and type of study (intervention, longitudinal, cross-sectional, others). Sample-size calculations indicated that 100 papers provide an 80% power to test a 55% standardized difference. We specified the main outcome as the increment in quality of papers as measured on the Goodman Scale. Two blinded evaluators rated the quality of manuscripts at initial submission and final post peer review version. Of the 327 manuscripts submitted to the journal, 131 were accepted for further review, and 129 were randomized. Of those, 14 that were lost to follow-up showed no differences in initial quality to the followed-up papers. Hence, 115 were included in the main analysis, with 16 rejected for publication after peer review. 21 (18.3%) of the 115 included papers were interventions, 46 (40.0%) were longitudinal designs, 28 (24.3%) cross-sectional and 20 (17.4%) others. The 16 (13.9%) rejected papers had a significantly lower initial score on the overall Goodman scale than accepted papers (difference 15.0, 95% CI: 4.6- 24.4). The effect of suggesting a guideline to the reviewers had no effect on change in overall quality as measured by the Goodman scale (0.9, 95% CI: 20.3+2.1). The estimated effect of adding a statistical reviewer was 5.5 (95% CI: 4.3-6.7), showing a significant improvement in quality. Conclusions and Significance. This prospective randomized study shows the positive effect of adding a statistical reviewer to the field-expert peers in improving manuscript quality. We did not find a statistically significant positive effect by suggesting reviewers use reporting guidelines.

Historical first descriptions of Cajal-Retzius cells: from pioneer studies to current knowledge

Santiago Ramón y Cajal developed a great body of scientific research during the last decade of 19th century, mainly between 1888 and 1892, when he published more than 30 manuscripts. The neuronal theory, the structure of dendrites and spines, and fine microscopic descriptions of numerous neural circuits are among these studies. In addition, numerous cell types (neuronal and glial) were described by Ramón y Cajal during this time using this 'reazione nera' or Golgi method. Among these neurons were the special cells of the molecular layer of the neocortex. These cells were also termed Cajal cells or Retzius cells by other colleagues. Today these cells are known as Cajal-Retzius cells. From the earliest description, several biological aspects of these fascinating cells have been analyzed (e.g., cell morphology, physiological properties, origin and cellular fate, putative function during cortical development, etc). In this review we will summarize in a temporal basis the emerging knowledge concerning this cell population with specific attention the pioneer studies of Santiago Ramón y Cajal.

Belleza y elocuencia, o la rendición por los sentidos (Lucianus, Scyth. 11)

In Lucian Scythian (§11), all previous editors have corrected the word ¢p£xetai as it appears in the manuscripts to p£xetai. We aim to justify the restoration of the original text because, obviously, it is possible in terms of form, and, besides, it seems more appropriate to the context. The verb ¢p£gomai implies the notion of being moved from one place to another, while p£gomai expresses only the notion of simple attraction which does not involve actual movement. This notion of true surrendering through the senses seems to match the idea developed here by Lucian; loci paralleli in Lucian himself and other Attic authors help us to confirm this interpretation.

Descripción del ms. 80 de la Zawiyya Hamzawiyya

La Zawiya Hamzawiya forma parte de las bibliotecas marroquíes descritas en les bibliothéques au Maro por Latifa Benjelloun-Larouil.

En este mismo artículo introducía un resumen de la historia de la ZÁvwya haciendo hincapié en los principales copistas que trabajaron en ella, así como en las expediciones locales y extranjeras que consultaron sus manuscritos.

El retorn a la vida. Treballs de restauració i estudi a dues peces del Museu Egipci de Barcelona

Es tracta de tres rotlles de papir, dos d’ells d’apariéncia iguals i el tercer ben diferent amb grandària i estat de conservació.Els dos primers de tamany i patologies semblants, enrotllats amb l’escriptura per la part interior,per la qual cosa en un principi no es podia identificar, semblaven ser el mateix rotlle partit pel elmig, el tercer, si be aparentava ser igual que els altres, venia plegat per un costat i més deteriorat, al desplegar-los resultaren ser tots tres la continuïtat del mateix text.

L’obra de Guillaume de Machaut en el Manuscrit Mòdena, Biblioteca Estense, a.M.5.24

Entre finals del segle XIV i principis del XV es data la redacció del Manuscrit Mòdena, Biblioteca Estense, .M.5.24, un dels principals manuscrits del moment que han arribat als nostres dies, essent un element culminant pel que fa a penetració de l’art polifònic francès a la Itàlia d’inicis del ‘400. En ell es copien quatre peces de Guillaume de Machaut i l’únic poema de l’autor francès musicat per un altre compositor. En els treballs sobre el manuscrit molt sovint s’obvien aquestes quatre peces, i l’estudi sobre Machaut es fa quasi exclusivament des de les fonts franceses. Aquest treball pretén respondre, sobretot, a dues preguntes: Què ens poden explicar aquestes peces sobre el procés d’afrancesament de la música italiana? Què ens poden explicar sobre la difusió de l’obra de Machaut pel vell continent?

Encuadernaciones Mudéjares de la Biblioteca de Alfonso el Magnánimo: Ms. 574 y 576 Biblioteca de la Universitat de Barcelona

This work expect to prove relations between the bookbinding of two manuscripts conserved in the Library of the University of Barcelona and the bookbinding to realise in the workshop of bookbinding of the Library of Alfonso el Magnanimous in this court Neapolitan, across over the study of this elements and architecture, and give the denomination of bookbinding mudejar neapolitan, because they are to make in this workshop or in this defect in Italy in the middle of the XV century.

Proposta d’un text articulat sobre teoria general del contracte per al Llibre sisè del Codi Civil de Catalunya

El treball que es presenta conté un text articulat sobre la part de teoria general del contracte (arts. 612-1 i següents) del llibre sisè del Codi Civil de Catalunya. El procés de codificació civil que es viu a Catalunya justifica aquest treball, que podria ser útil per a elaboració del llibre sisè del CCCat dedicat a les obligacions i els contractes. El treball consta d’una proposta de text articulat, amb el seus respectius comentaris a cada article. Es tracta del capítol segon del títol primer del llibre sisè, i es divideix en les següents seccions: 1) El contracte, els seus elements essencials, i la seva eficàcia; 2) La formació del contracte; 3) La interpretació del contracte; i 4) La ineficàcia del contracte, que inclou l’anàlisi dels vicis del consentiment. El treball ha pres com a referència les principals propostes d’harmonització del dret contractual (Principis Unidroit [PICC], Principis de Dret Contractual Europeu [PECL], Marc Comú de Referència [DCFR], i l’Instrument Opcional sobre Compravenda Europea [CESL] i la regulació dels codis més moderns (entre ells, el del Quebec, l’Holandès, el Portuguès o l’Italià) i les seves propostes de reforma (el projecte Terrè a França, i la Propuesta de Modificación del Código Civil Español en materia de obligaciones y contratos). En la proposta presentada s’incorporen institucions no regulades en el Codi civil espanyol actualment vigent a Catalunya en la seva condició de dret supletori, i s’omplen algunes llacunes d’aquest cos legal. Es poden citar, entre elles, les clàusules abusives dels contractes, el canvi en les circumstàncies essencials del contracte, el contracte per a persona per designar, la responsabilitat per culpa in contrahendo, les cartes d’intencions, el règim de l’oferta i l’acceptació del contracte, els contractes preparatoris, els drets de preferència, la possibilitat d’anul·lació del contracte per concessió d’un avantatge injust a alguna de les parts, i el règim dels contractes en frau de creditors.
