    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    Dispelling the Myths Behind First-author Citation Counts

    We 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

    Fakultas Kedokteran Gigi Universitas Jember Jl. Kalimantan 37 JemberInterpretasi hasil pemeriksaan histologik sangat ditentukan oleh hasil visualisasi gambaran preparat histologi. Permasalahan yang sering dijumpai di dalam laboratorium histologi adalah kualitas gambar yang kurang baik, di sebabkan oleh metode pengecatan yang kurang optimal. Salah satu alat yang di gunakan adalah automatic slide stainer alat yang diproduksi oleh luar negeri, sehingga setting manual;nya belum disesuaikan dengan kondisi kebutuhan di Indonesia, misalnya optimalisasi suhu, resep reagen pewarna. Oleh karena itu perlu dilakukan penelitian ini untuk mengetahui profil preparat histologi dengan pewarnaan jaringan rutin Haematoksilin-Eosin (HE) dengan menggunakan Automatic Slide Stainer untuk mengoptimalkan metode tersebut, agar dapat di manfaatkan sesuai dengan kondisi kebutuhan laboratorium setempat. Tujuan dari melakukan optimalisasi alat automatic slide stainer untuk pengecatan jaringan dengan haemotoksilin-eosin. Penelitian ini akan membandingkan hasil pewarnaan jaringan menggunakan haemotoksilin-eosin dengan perlakuan perbedaan suhu (20OC, 22OC, 25OC) dan perbedaan resep pewarnaan. Parameter penelitian adalah jumlah sel otot yang intinya (nucleus) terwarna secara optimal (berwarna biru), apabila masih berwarna merah muda berarti metode belum optimal. Hasil penelitian menunjukkan, pada suhu 20OC dan 22OC terlihat warna yang lebih pucat, sedangkan pada suhu 25OC, terlihat warna yang komposisinya sudah terlihat proposional.Hibah Penelitian Non Dose

    Pragmatic Case Studies as a Source of Unity in Applied Psychology

    No full text
    To unify or not to unify applied psychology: that is the question. In this article we review pendulum swings in the historical efforts to answer this question—from a comprehensive, positivist, “top-down,” deductive yes between the 1930s and the early 60s, to a postmodern no since then. A rationale and proposal for a limited, “bottom-up,” inductive yes in applied psychology is then presented, employing a case-based paradigm that integrates both positivist and postmodern themes and components. This paradigm is labeled “pragmatic psychology” and, its specific use of case studies, the “Pragmatic Case Study Method” (“PCS Method”). We call for the creation of peer-reviewed journal-databases of pragmatic case studies as a foundational source of unifying applied knowledge in our discipline. As one example, the potential of the PCS Method for unifying different angles of theoretical regard is illustrated in an area of applied psychology, psychotherapy, via the case of Mrs. B. The article then turns to the broader historical and epistemological arguments for the unifying nature of the PCS Method in both applied and basic psychology.Peer reviewe

    Appropriate Similarity Measures for Author Cocitation Analysis

    No full text
    We 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

    Synthesis, spectroscopic and structural properties of an unusual series of homoleptic phosphine oxide complexes of the alkaline earth dications

    The distorted tetrahedral [M(OPPh3)(4)](SbCl6)(2) (M = Mg, Ca, Sr) are obtained from MCl2, OPPh3 and SbCl3 in suitable solvent conditions, while Ba2+ gives [Ba(OPPh3)(5)](SbCl6)(2). The chelating o-C6H4(P(O)Ph-2)(2) gives the tris complexes [M{o-C6H4(P(O)Ph-2)(2)}(3)](SbCl6)(2), while under similar conditions the stoichiometries of the products obtained using Ph2P(O)CH2P(O)Ph-2 vary, with M; and products include the five-coordinate [Mg{Ph2P(O)CH2P(O)Ph-2}(2)(H2O)](SbCl6)(2), the distorted octahedral [M{Ph2P(O)CH2P(O)Ph-2}(3)](SbCl6)(2) (M = Ca or Sr) and the seven-coordinate [Sr{Ph2P(O)CH2P(O)Ph-2}(3)(EtOH)](SbCl6)(2). Strontium is unusual in that both six- and seven-coordinate species are evident and may be isolated depending upon the reaction conditions. These are the first reported Group 2 complexes with bidentate phosphine oxides and there are no other phosphine oxide complexes with Sr or Ba. Crystal structures are reported for {Mg(OPPh3)(4)](SbCl6) (2).CH2Cl2 [Ca{Ph2P(O)CH2P(O)Ph-2}(3)] (SbCl6)(2).2CH(2)Cl(2) and [Sr{Ph2P(O)CH2P(O)Ph-2}(3)(EtOH)](SbCl6)(2).0.45CH(2)Cl(2). The compounds isolated show significant dependence upon the charge:radius ratio of the metal and the steric bulk and rigidity of the ligand

    Measurement of the ratio of branching fractions B(B0→K∗0γ )/B(B0s→φγ ) and the directCP asymmetry inB 0→K∗0γ

    The ratio of branching fractions of the radiative B decays B0→K⁎0γ and B0s→ϕγ has been measured using an integrated luminosity of 1.0 fb−1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of s√=7TeV. The value obtained is B(B0→K⁎0γ)B(B0s→ϕγ)=1.23±0.06(stat.)±0.04(syst.)±0.10(fs/fd), where the first uncertainty is statistical, the second is the experimental systematic uncertainty and the third is associated with the ratio of fragmentation fractions fs/fd. Using the world average value for B(B0→K⁎0γ), the branching fraction B(B0s→ϕγ) is measured to be (3.5±0.4)×10−5. The direct CP asymmetry in B0→K⁎0γ decays has also been measured with the same data and found to be ACP(B0→K⁎0γ)=(0.8±1.7(stat.)±0.9(syst.))%. Both measurements are the most precise to date and are in agreement with the previous experimental results and theoretical expectations
