Mitochondrial cytochrome c oxidase subunit 1 (cox1) gene sequence of Spirocerca lupi (Nematoda, Spirurida) from different geographical areas: avenues for potential implications
No full textCanine spirocercosis is a life-threatening parasitosis caused by Spirocerca lupi (Nematoda, Spirurida) that is presently emergingin several countries. This study characterised an informative region within the mitochondrial (mtDNA) gene encoding for thecytochrome c oxidase subunit 1 (cox1) of S. lupi by Polymerase Chain Reaction (PCR)-coupled sequencing. Specimens from fivedifferent countries in Europe, Asia and Africa were examined and two different sequence variants of cox1 (i.e. haplotypes) weredetermined, displaying nucleotidic variation at 6 of 689 positions. All of these positions were invariable among all the parasiteindividuals from Europe (haplotype 1) and among the African and Asian individuals (haplotype 2), but differed between Europe andAsia/Africa. The S. lupi cox1 sequences were consistent with those of other common Spirurida previously reported at bothnucleotidic and phylogenetic levels. This study provides molecular information essential for identification of the nematode,irrespective of its life cycle stage. Crucial implications for the specific molecular diagnosis of clinical spirocercosis andinvestigation of the evolution, population genetics, ecology and epidemiology of S. lupi are discussed.[...
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.
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
Alleviating transitory food crisis in Africa : international altruism and trade
No full textThis paper focuses on criticism about the use of emergency food aid in sub-Saharan Africa. More specifically, it examines the response of the donor community to unexpected or transitory drops in domestic food production in 26 countries. The study compares the role of food aid and commercial food imports in offsetting these shocks and covering the shortfall in food consumption. Several hypotheses that determine the tendency of donors to respond to the needs of different countries are tested. The results suggest that food aid and commercial food imports stabilize food consumption and neutralize the effects of random shocks to domestic production. Food aid compensates for up to 50 percent of the drop in food production; imports make up an additional 30 percent. This paper documents the stylized facts of food insecurity in Africa and shows the relative importance of emergency and total food aid to food production and food shortages. The paper includes an empirical framework for the estimation and analysis of the correlation between food aid and food production and presents the results. Lastly, the paper elaborates on the economic and political determinants that affect the global response to the emergency needs of countries in Africa.Food&Beverage Industry,Food&Nutrition Policy,Development Economics&Aid Effectiveness,Environmental Economics&Policies,School Health
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
