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.
Bakırlı Rahim İçi Aracın Simule Rahim Sıvısına Etkileri
No full textDeğişik doğum kontrol yöntemleri olmasına rağmen, bunların içinde bakırlı Rahim İçi Araç (RİA) adı ile anılan çeşitleri yaygın olarak kullanılmaktadır. Ancak içeriğinde bulunan bakır (Cu) nedeni ile kullanımının uygunluğu konusunda alternatif görüşler vardır. RİA’nın içeriğindeki bakırın vücutta korozyona uğraması sonucu korozyon artıklarının miktarı ve korozyon hızı; farklı marka ve modellerde değişebilmektedir. Bunun için farklı marka ve modellerde seçilmiş RİA’ lar; NaHCO3, NaH2PO4.2H2O, Glikoz, NaCl, CaCl2, KCl içerikli, 37°C sıcaklıkta, 6,3 ve 8 olmak üzere iki farklı PH değerlerinde hazırlanan simule rahim sıvıları içerisinde Galvanik Potansiyostat cihazı kullanılarak korozyona uğratılmıştır. İlgili düzenek kullanılarak korozyon hızı; Tafel Ekstrapolasyon Yöntemi ile belirlenmiştir. Her bir deney sonucu elde edilmiş farklı korozyon ürünü maddeleri taşıyan simule sıvılar; Atomik Absorbsiyon Spektrometre (AAS) yöntemi ile içerdikleri bakır miktarı bakımından analiz edilmiştir. Korozyon hızında her iki pH değerleri arasında farklılıklar kaydedilmiştir. Ayrıca korozyon ürünlerinin miktarı her iki pH değerinde de tartışmaya açık miktardadır. RİA’nın kullanımının kontrol altına alınmasını gerektirebilecek sonuçlar doğabilecektir. Anahtar kelimeler: Korozyon, Elektrokimya, Simule rahim sıvısı, Bakır RİA Despite the availability of various contraceptive methods, types named as copper Intra Uterine Device (IUD) are widely used among these. However, there are alternative views about the proper usage of it due to the Copper (Cu) content. As a result of corroding copper within the IUD inside the body, amount of corrosion products and corrosion velocity may vary with different brands and models. Therefore, selected IUDs of different brands and models are corroded by using a galvanic potentiostat device inside prepared simulated uterine fluids including NaHCO3, NaH2PO4.2H2O, glucose, NaCl, CaCl2, KCl, at 37 ºC and at 2 different pH values such as 6.3 and 8. By using mentioned mechanism; corrosion velocity is determined by Tafel Extrapolation Method. Simulated liquids carrying different corrosion product materials which are obtained with each experiment are analyzed in terms of containing copper amount by Atomic Absorption Spectrometry (AAS) method. Differences of corrosion rate between two different pH values are recorded. Besides, amount of corrosion products is at disputable level for both pH values. Consequences to require taking control of IUD usage may occur. Keywords: Corrosion, Electrochemistry, Simulated uterine fluid, Copper IUD </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

RSUD Dr. Pimgadi Medan Tahun 2012 telah dilakukan. Tujuan penelitian ini
adalah untuk mengetahui hubungan jumlah paritas anak dengan angka kejadian
kanker leher rahim di RSUD Dr. Pirngadi Medan Tahun 2012. Penelitian
dilakukan pada bulan Januari 2013 di RSUD Dr. Pirngadi Medan. Bahan dalam
penelitian ini menggunakan data rekam medik yaitu penderita kanker leher rahim
yang datang memeriksakan di RSUD Dr. Pirngadi Medan Tahun 2011-2012.
Metode penelitian dilakukan secara deskriptif analitik. Adapun sampel dalam
penelitian ini adalah penderita kanker leher rahim yang diambil dari data rekam
medik di RSUD Dr. Pirngadi Medan tahun 2011-2012. Hasil penelitian diperoleh
pasien KLR terbesar pada paritas lebih dari 2 orang anak (multipara) (70,2%),
kemudian grandemultipara (26,9%) dan primipara (2,9%). Hasil korelasi
hubungan multipara dengan stadium kanker leher rahim diperoleh nilai R
(18,23%), clan grandemultipara dengan stadium kanker leher rahim nilai R
(0,92%). Hasil regresi diperoleh multipara dan grandemultipara bertanda positif
dan signifikan terhadap kejadian kanker Ieher rahim yang berarti multipara dan
grandemultipara bukan merupakan faktor penentu terjadinya kanker leher rahim
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
