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.
EV ZİYARETLERİ İLE YÜRÜTÜLEN GEBE İZLEMLERİNİN PERİNATAL SONUÇLARA ETKİSİ
No full text<p>Gebelikte bir program eşliğinde ev ziyareti, olası olumsuz doğum sonuçlarını önlemek için kapsamlı ve önemli bir stratejidir. Araştırmanın amacı, birinci basamakta yürütülen doğum öncesi bakımın ev ziyaretleri ile desteklenerek yürütülmesinin perinatal sonuçlara etkisini incelemektir. Temmuz 2020-Ocak 2022 tarihleri arasında randomize kontrollü ön test son test kontrollü deneysel bir araştırma olarak yürütüldü. Kadıköy bölgesinde aile sağlığı merkezlerinde kayıtlı ilk trimesterda olan 32 gebe girişim, 32 gebe kontrol grubu olmak üzere toplam 64 gebe ile başlanıp 56 gebe ile araştırma tamamlandı. Gebelerin ilk izlemi aile sağlığı merkezinde yapıldı ve sonraki izlemler ev ziyareti izlem programına göre sürdürüldü. Araştırma verileri gebelerden Tanıtıcı Bilgi Formu, Perinatal Bilgi Formu, Doğum Sonu Görüşme Formu, Emzirme Öz Yeteriliği Ölçeği ve Edinburgh Doğum Sonu Depresyon Ölçeği ile toplandı. Araştırma; girişim grubundaki gebelerin ev ziyareti ile yürütülen gebe izlem programından tam bir memnuniyet duymasını ve kontrol grubuna göre nitelikli bir doğum öncesi bakım almasını sağladı. Ev ziyareti ile yürütülen gebe izlem programı ile girişim grubunun Perinatal Bilgi Formu puanları anlamlı olarak yükseldi. Girişim grubunda Perinatal Bilgi Formu puanı arttıkça gebelerin vajinal doğum planlama oranları anlamlı olarak arttı. Ancak girişim grubu ile kontrol grubu arasında vajinal doğum yapma oranları açısından anlamlı bir fark bulunamadı. Ev ziyareti ile girişim grubundaki kadınların ilk emzirme ve sonraki emzirme süreleri kontrol grubuna göre anlamlı olarak yükseldi. Sonuç olarak ev ziyareti ile yürütülen gebe izlemleri, gebelerin perinatal döneme özgü bilgi durumlarının, vajinal doğum yapma isteklerinin, ilk emzirme ve sonraki emzirme sürelerinin artmasında etkili bir model olduğu belirlendi.</p>
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
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
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

Egyptian blue pigment in East Mediterranean wall paintings: A study of the lifetime of its optical infrared emission
No full textThis study presents advances in the application of laser-based methods to image and measure the luminescence lifetime of historical wall paintings containing Egyptian blue. Samples from Tel Kabri, a major Canaanite palace dated to 18th C. BCE, from the Roman city of Caesarea Maritima, from the 4–5th C. Byzantine tomb in Lohamei HaGeta'ot, and from a 6th C. Byzantine church of Shivta have been studied using time-resolved photoluminescence spectroscopy and imaging. Taking into account the high sensitivity of the emission lifetime to the microenvironment surrounding the emitting species, here, we show for the first time that the optical emission from historical samples containing Egyptian blue particles exhibits meaningful lifetime variations. Indeed, the wall paintings from Tel Kabri, Lohamei HaGeta'ot, and Shivta present the shortest emission lifetime, close to 115–120 μs. However, samples from Caesarea Maritima wall paintings exhibit a different optical emission, which dumps more slowly with an average lifetime of 130 μs. Egyptian blue pigment particles, synthetised with modern methods, are associated with the longest emission lifetime of 147 μs. This study suggests that there is a possible link between the lifetime of the pigment's emission and its synthesis method
