Nutritional and botanical interest of honey collected from protected natural areas
No full textDue to numerous episodes of contamination through illegal beekeeping practices, the certification and re-evaluation of honey is required to guarantee a clean, natural and healthy product. The aim of this work was to demonstrate the good quality of honey produced in protected areas by demonstrating both its nutraceutical content and its role in monitoring the plant species present in protected areas. All the physico-chemical parameters necessary for defining the quality of honey (botanical origin; conductivity; diastase activity; pH; free, lactonic and total acidities; water content; fructose, glucose and sucrose content; hydroxymethylfurfural) and total flavonoid and phenolic contents were analyzed and evidenced its high quality. Moreover, melissopalynology allowed us to establish a floristic census within the nature reserves and parks
Prospective randomized multicentre trial comparing stapled with open haemorrhoidectomy
No full textBackground: The aim of this study was to compare the results of conventional open haemorrhoidectomy as currently practised in Italy (group 1) with stapled haemorrhoidectomy using a 33-mm circular stapling device (group 2). Methods: One hundred patients with symptomatic third- and fourth-degree haemorrhoids were enrolled by five hospitals. Patients were allocated to the two groups according to a centralized randomization scheme featuring five permutated blocks of 20. Preoperative clinical examination and anorectal manometry demonstrated no features of anal incontinence. Patients had a clinical and manometric re-evaluation after operation and were asked to complete a clinical diary. After a median of 16 (range 8-19) months patients were administered a standardized questionnaire by telephone. Results: Postoperative bleeding requiring haemostatic procedures occurred in three patients in each group. Patients in group 1 complained of moderate pain for a median of 5.3 (range 0-19) days compared with 3.1 (range 0-10) days in group 2 (P = 0.01), while severe pain was present for 2.3 (range 0-24) days in group 1 but only for 1 (range 0-14) day in group 2 (P = 0.03). The median hospital stay was 2 days in group 1 compared with 1 day in group 2 (P = 0.01). In the early days after operation, patients in group 2 had greater difficulty in maintaining normal continence to liquid stools (P = 0.01), but after 30 days the continence score was better in group 2 (P = 0.04). Conclusion: Stapled haemorrhoidectomy is as effective as conventional haemorrhoidectomy. Reduced postoperative pain, shorter hospital stay and a trend toward earlier return to work suggest short-term advantages for the stapled technique
MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank

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
"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.
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
