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
Corporate Social Responsibility of Large Retailers. An International Comparison
No full textNowadays, as companies are usually a part of a network of relationship, they need legitimacy to operate in an increasingly international competition market. The world is increasing its focus on environmental, ethical and social issues, and this has recently prompted companies to draw up their own annual Activity and Corporate Responsibility Report in order to create added value for their stake-holders. The aim of this paper is to analyze six major retailers listed in Deloitte's global ranking of retailers, and compare their corporate social responsibility poli-cies using a conceptual model composed of four areas: 1) company, 2) products and assortments, 3) social commitment, and 4) environmental commitment. The comparative analysis shows up some differences between retailers from different countries of origin and proposes a new starting point for future research
"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.
A Novel Semantic Approach to Document Collections
No full textAvailable document collections are more and more required for supervised text categorization tasks. They typically are
collections of documents classified by domain engineers. In this paper, we propose a semantic text categorization
approach able to automatically create document collections in which documents are classified according to WordNet
Domains taxonomy. Experiments have been performed by training a classifier with an automatic document collection and
comparing results with those obtained by training the same classifier on a hand-made document collection. Experimental
results point out that, on average, the performances of the automatic approach are quite similar to those obtained on a
document collection classified by domain engineers
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
New trends of progestins treatment of endometriosis
No full textThe management of endometriosis with OC or progestins is generally safe, effective and well-tolerated and should constitute the first line of medical treatment in symptomatic patients who do not want to have children. Progestins, synthetic progestational agents, have been used in the management of symptomatic endometriosis both as primary therapy and as an adjunct to surgical time. A variety of oral agents have been employed in this regard and investigators have demonstrated differing degrees of benefit. The lack of a standardized instrument to evaluate painful symptoms makes comparative analysis more difficult. Concern about efficacy and side effect has pushed the research on the development of new well-tolerated drugs and to develop new administration routes to minimize general side effects. Aim of the present review is to present the results of clinical studies on new trends of progestins in the treatment of endometriosis
TGF-β in cancer: Metabolic driver of the tolerogenic crosstalk in the tumor microenvironment
No full textOvercoming tumor immunosuppression still represents one ambitious achievement for cancer immunotherapy. Of note, the cytokine TGF-β contributes to immune evasion in multiple cancer types, by feeding the establishment of a tolerogenic environment in the host. Indeed, it fosters the expansion and accumulation of immunosuppressive regulatory cell populations within the tumor microenvironment (TME), where it also activates resident stromal cells and enhances angiogenesis programs. More recently, TGF-β has also turned out as a key metabolic adjuster in tumors orchestrating metabolic pathways in the TME. In this review, we will scrutinize TGF-β-mediated immune and stromal cell crosstalk within the TME, with a primary focus on metabolic programs
Letter from R. R. Zellick, Assistant Trust Officer, Anglo California National Bank of San Francisco, to Joseph R. Goodman, October 2, 1942
No full textLetter from R. R. Zellick, Assistant Trust Officer at The Anglo California National Bank of San Francisco, to Joseph R. Goodman, regarding property owned by Dave Tatsuno. Zellick mentions a dispute between current tenants and Tatsuno, and that Tatsuno has asked Goodman to help locate trustworthy tenants.Personal correspondence, organizational records, government documents, publications, and other papers created or collected by Joseph R. Goodman documenting the forced removal and incarceration of Japanese Americans during World War II, as well as organized resistance to incarceration. Included in the collection are records of the Japanese Young Men's Christian Association and the Japanese American Citizens' League in San Francisco, including papers of the Japanese YMCA's executive secretary Lincoln Kanai; Sakai family papers; Goodman's correspondence to and from Japanese American incarcerees, organizations opposing forced removal and incarceration of Japanese Americans, the War Relocation Authority, and others; publications, photographs, and ephemera from the Topaz Relocation Center, where Goodman taught high school; War Relocation Authority records and publications; and newspaper clippings, pamphlets, and reports about forced removal and incarceration created by various government, religious, and civic organizations, in California and nationwide
