D i a g n o s i s: Palnia thailandica nov.sp. is very similar to P. cambeforti KRÁL, 1999. The new species is larger (2.8-3.0 mm, compared to 2.4-2.6 in P. cambeforti) and in shape of the male genitalia (elongate, wide rounded apices in dorsal view, compared to stout, narrow apices in dorsal view). The new species differs from P. loebli STEBNICKA, 1985 and P. stebnickae CAMBEFORT, 1989 in having a short row of 7-9 short, imbricated setae on the meso- and metatibia. Additional characters for differentiation are in the key below.Published as part of Bellmann, Axel, 2020, A new Palnia STEBNICKA, 1985 species from Oriental region (Coleoptera, Scarabaeidae, Aulonocneminae), pp. 89-92 in Linzer biologische Beiträge 52 (1) on pages 89-90, DOI: 10.5281/zenodo.452650
To recruit skilled workers or to train one's own? : vocational training in the face of uncertainty as to the rate of retention of trainees on completion of training
No full text"The article deals with the impact of uncertainty as regards the retention of trainees completing vocational training programmes on firms' training behaviour. As an alternative to vocational training, the external recruitment of skilled workers is considered via an opportunity costs approach. The uncertainty is traced back to staff turnover, considerable product market competition and changing skill requirements. Indicators of these causes of uncertainty are examined as to their impact on vocational training and the recruitment of skilled workers with a fractional logit model, using a seemingly unrelated cluster-adjusted sandwich estimator with data from the IAB Establishment Panel. There is no confirmation that the presumed correlations exist in manufacturing. A negative correlation is identified in the service sector between high staff turnover coupled with rapid change in the skills required on the one hand, and commitment to vocational training on the other, while there is a positive link with the external recruitment of skilled workers. This is interpreted as an indication that uncertainty with regard to retention after training can go some way towards explaining the growing gap between employment and vocational training in the tertiary sector."

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

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
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
