ANÓNIMO, «Traducción en prosa de La dama priora»
No full textLa dama priora (The Lady Prioress) es un poema anónimo del siglo xv que se conserva en el manuscrito de la Biblioteca Británica de Londres, MS Harley 78, fols. 74 r-77 v. El poema consta de seis páginas y media, y combina versos aliterativos con otros que no lo son. El poema narra la historia de una hermosa priora que, debido a su gran belleza, atrae la atención de tres pretendientes: un joven caballero, un párroco-sacerdote, y un mercader. Los tres insistirán a la dama para que les conceda su amor y sus favores. La priora, mujer casta y pura, tratará con su astucia e ingenio de idear la manera de librarse de estos tres pretendientes, y defender su castidad a toda costa. Y, al final, lo conseguirá engañando a los tres pretendientes y dándoles una lección que nunca olvidarán
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
The clinical presentation in adulthood of juvenile idiopathic arthritis
No full textJuvenile idiopathic arthritis (JIA) is a chronic systemic inflammatory disease, which affects children and adolescents, characterized by significant differences when compared to inflammatory rheumatisms in adulthood. Today, in a panorama enriched in the last decades with great improvements in the diagnostic and therapeutic field, a far from negligible portion and an increasing number of patients with JIA require the continuation of treatments in adulthood. This specific population of patients, given the high incidence of extra-articular manifestations, residual irreversible disabilities, comorbidities related to an inflammatory process and extended immunosuppressive treatments during the age of development, requires precise attentions in the follow-up and a multidisciplinary approach characterized by different clinical, psychological and social aspects
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Ultrasound-guided intra-articular injection: Efficacy of hyaluronic acid compared to glucocorticoid in the treatment of knee osteoarthritis
No full textBACKGROUND: Osteoarthritis (OA) is a degenerative joint disease which causes pain and functional impairment in adults over 50 years old with consequent important disability. Unfortunately, there is no definitive cure for OA, thus the approach is characterized by multiple treatments that can manage its symptoms. Even though data from randomized controlled trials and meta-analyses indicate that intra-articular hyaluronic acid (IAHA) offers the best benefit/risk balance among the various pharmacologic treatments to improve OA-related knee pain, there is a lack of agreement among national and international guidelines about such uses of IAHA for the medical management of symptomatic knee OA. To minimize confounding factors and biases, the aim of our study was to evaluate the efficacy of the different weight and concentration of IAHA treatment in patients suffering from knee OA comparing to glucocorticoids (GC) joint injections. Furthermore, to make the procedure more accurate and assessment more objective, we use ultrasonography (US) with power Doppler (PWD) to help us differentiate between active and inactive inflammation within joints and periarticular soft tissues. METHODS: We performed a retrospective evaluation of a cohort of patients with knee OA, diagnosed according to the ACR criteria, treated by US-guided joint injection of HA and GC. The patients were catalogued according to the type of treatment they underwent: group A, patients treated with HA (1.5%) >1500 kDa (three US-guided knee injections one week apart); group B, patients treated with HA (2%) 800-1200 kDa (three US-guided knee injections one week apart); group C, patients treated with glucocorticoids (three US-guided knee injections of triamcinolone acetate 40 mg one week apart). All patients were monitored for 6 months, evaluating: subjective pain using a 10-cm Visual Analogue Scale; pain, stiffness, and functionality using the Western Ontario and McMaster Universities Arthritis Index (WOMAC); the concomitant intake of anti-inflammatory and/or analgesic drugs through a questionnaire; and US results by grey scale and PWD. RESULTS: A total of 171 patients affected by knee OA were evaluated (women 72.3%) with a mean age of 69.3±4.1 years. All the subjects analyzed showed a pain reduction at 6 months after treatment (group A: -39.5; group B: -36.9; group C: -30.8). The difference between the three groups was statistically significant (Kruskall-Wallis P=0.001) and in particular between group A and group C (P=0.000) and between group B and group C (P=0.005), but not between A and B (P=0.258). WOMAC was statistically significantly improved from baseline in all groups examined (group A: -11.9; group B: -14.9; group C: -11.2). The PWD score showed a statistically significant improvement in group B (-0.64) even after 6 months (P=0.004). All patients in the different groups showed a statistically significant reduction of concomitant therapy compared to baseline with respect to paracetamol and non-steroidal anti-inflammatory drugs (NSAIDs)/COX2 therapy, while only group B showed a statistically significant reduction for opioids. CONCLUSIONS: This study demonstrated the efficacy of OA treatment with medium molecular weight HA in favor of the higher concentration of HA that may affect the reduction of pro-inflammatory mediators. Furthermore, US monitoring allowed to evaluate aspects related to synovial involvement, which cannot be appreciated with standard imaging
Measurement of Mixed Disulfides Including Glutathionylated Proteins
No full textMixed disulfides between protein cysteines and low-molecular-weight thiol cysteine or glutathione lead to the formation of cysteinylated proteins or glutathionylated proteins. These types of posttranslational modification are of great importance in the so-called redox regulation, by which changes in the redox state of the cell regulate a number of biochemical processes. We describe the methods for quantitatively measuring the various redox states of cellular thiols including protein cysteines and these mixed disulfides. These include spectrophotometric methods, which do not distinguish between protein-cysteine and protein-glutathione disulfides, and HPLC methods that make such distinction. Finally, we report a method for labeling proteins susceptible to glutathionylation with biotin, to allow their visualization by Western blot after electrophoretic separation, which is used to identify proteins undergoing this posttranslational modification. © 2010 Elsevier Inc

Report on the existing legal framework for Libraries and Archives (LA) industries in EU
No full textThe present report is one of two deliverables drafted for the purposes of Task 5.1 - European legal framework for GLAM industries: from closure to Openness of the reCreating Europe’s Work Package (WP) 5, which aims at providing a map of EU and national copyright provisions that have an impact on digitisation practices by Galleries, Libraries, Archives, and Museums (GLAMs). This report focuses on Galleries and Museums (GM) and builds on the first deliverable (D5.2 Report on the existing legal framework for Libraries and Archives (LA) industries in EU) – dedicated to Libraries and Archives (LA) and delivered in Month 12.
The analysis specifically purports to complete the picture of copyright regulation from the perspective of the GLAM sector, as well as to further deepen the analysis adding EU and national insights to the recollection of relevant legal sources. For this reason, the report fundamentally embraces the same methodology followed by the preceding deliverable, namely a systematic legal analysis of EU and national legal sources. However, instead of looking at all EU Member States (MSs), it strategically focuses more in details on seven selected countries (Denmark, Estonia, Germany, Hungary, Ireland, Italy, The Netherlands) and one former MS (the United Kingdom) that was not considered in the former report. The targets were chosen as representative of the transposition of the CDSM and because of the interest raised by their comparison and resources for the analysis.
The present report confirms one of the findings of the former report, that is the growing relevance of sector-specific copyright exceptions and limitations at EU level, while it also emphasises the structural differences that still feature in the national implementations of EU laws and exacerbate the risk of creating legal uncertainty and impairing cross-border transactions. Overall, the analysis confirms the need for a continuing regulatory effort towards effective copyright reform tackling the needs of the GLAM sector, especially considering the opportunities related to the digital environment.
The deliverable is under acceptance by the European Commission
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
