Veure Àfrica a través de la mirada de Riszard Kapuściʼnski

El profund i humaníssim interès i la defensa que va exercir Ryszard Kapuściński de la identitat cultural africana constitueix un model a seguir sobre la construcció i el tractament dels “altres” en els textos periodístics. El present treball analitza la vida i la obra del corresponsal polonès per tal de plantejar qüestions com l’etnocentrisme del discurs dels mitjans de comunicació, la importància d’un tractament de subjecte de les fonts, la identitat cultural o la comunicació intercultural. A través dels objectius amb els quals Kapuściński definia el periodisme –“traductor de cultures” i “advocat d’Àfrica”- i la manera com exercia la professió de corresponsal es planteja quina és la visió i la mirada que Occident i el periodisme tenen de les altres cultures –establint com a context la civilització africana en el procés de descolonització del continent- i la necessitat d’una pràctica periodística respectuosa amb la diversitat cultural.

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.

Large gypsum nodules in the Paleogene and Neogene evaporites of Spain: distribution and palaeogeographic significance

Sabkha and deep burial set tings are the most com mon sites where diagenetic anhydrite forms. In a sabkha setting, displacive facies (iso lated nodules, bed ded nodules, enterolithic levels) of early diagenetic or primary anhydrite are generated (Shearman, 1966; Hardie, 1967). These anhydrite facies are commonly foundat the top of shoal ing cycles representing the evolution from subaqueous depositional conditions at the base (carbonates, lutites) to exposure conditions at the top where in ter stitially-grown gypsum/anhydrite de velops ( sabkha cy cles). In a deep burial setting, gypsum transforms to tally to anhydrite with in creas ing temperature and lithostatic pressure (Murray, 1964). Al though this mineral transformation usually preserves the depositional gypsum facies, a significant textural change is in volved in other cases, resulting in replacive anhydrite with a nodular-mosaic or"chicken-wire" fabric (Warren, 2006). In the two settings, how ever, the size of the individual anhydrite nodules is relatively small, rarely reaching some tens of centimetres across. More over, bedding is preserved or little disturbed, al though minor de formation is caused by the displacive sabkha nodules.

Occurrence of a new sulphate mineral: Ca7Na3K(SO4)9 in the Emet borate deposits, western Anatolia (Turkey)

This paper is a preliminary report on the petrographic and geochemical characteristics of a new sulphate mineral associated with lacustrine glauberite layers. This mineral is present in two boreholes recently drilled in the Emet borate district (Mio-cene; western Anatolia , Turkey). The evaporitic succession in these boreholes is mainly formed of a glauber ite-probertiteal-ternation. We suggest the name"emetite", after the town of Emet, for the new sulphate mineral, although the fine crystal size hinders the appropriate chemical and crystallographic characterization required to propose it as a new mineral to the International Mineralogical Association. .

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.
