No full textGoing 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
Effects of parenteral nutrition on the immune system in patients with head and neck squamous cell carcinoma
No full textOncologic patients often face malnutrition, particularly in the case of head and neck squamous cell carcinoma(HNSCC), due to the site of the lesion that may hinder swallowing. Malnutrition is associated with immunosuppression and increased incidence of infections and mortality, and improving the nutritional status with support regimes, such as parenteral nutrition (PN) can restore immune competence.The bags destined for PN contain mostly lipids and are enriched with essential fatty acids, specifically polyunsaturated fatty acids (PUFAs) ω3 and ω6. It is now clear that lipids, including PUFAs, influence the immune system: ω3 have an anti-inflammatory effect, thus repressing the immune response, whereas ω6 promote Th1-like responses.Although current guidelines suggest caution in the use lipid emulsions of ω6 in patients with uncontrolled inflammatory responses, such as those underlying autoimmune diseases, these may instead be advisable in patients unable to develop an adequate antitumoral response.Thegoal of clinical research is the personalization of therapies which include supportive therapies, such as nutritional support. It is indeed possible to predict that, in the near future, the individualized choice of specific nutrients could allow the patient not only to deal with chemotherapy with less toxicity, but also to promote advantageous immune responses and, therefore, survival
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
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

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

Outcome of T1N0M0 breast cancer in relation to St. Gallen risk assignment criteria for adjuvant therapy
No full textT1N0M0 (stage 1) breast cancer (BC) has been increasing in recent decades but the optimal adjuvant approach remains controversial. To assess the outcome of BC patients stratified and treated with multimodal therapies according to St. Gallen consensus meeting recommendations, we retrospectively evaluated an unselected cohort of T1N0M0 BC patients, with respect to the St. Gallen criteria. At a median follow-up of 5 years, the recurrence rate, recurrence-free survival and overall survival were 7%, 94% and 96% respectively, and 60% of relapses were locoregional. No statistically significant difference was observed between T1a,b/T1c groups, or among risk categories (high/intermediate/low). The very low rate of distant recurrences even in patients with unfavorable prognostic factors seems to support the use of adjuvant systemic therapies but better prognostic and predictive factors are strongly needed for this subset of patients
