    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    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

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    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

    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

    CRACKS IN REINFORCED CONCRETE BEAM

    Full text link
    Cracks in concrete cannot be prevented but the size of the cracks can be controlled. Cracks that occur in concrete are strongly influenced by the nature and characteristics of the concrete constituent materials, especially cement and water. Cracks can occur in the fresh and hard concrete phases. Cracks that occur in concrete can be grouped into two, non-structural cracks and structural cracks. There are several types of non-structural cracks such as crazing, map cracking, plastic cracking due to shrinkage, plastic cracking due to settlement, cracking due to drying shrinkage, cracking due to temperature changes, cracking due to chemical reactions. Structural cracks can be caused by the effects of vibration, earthquake and loads that work beyond capacity. Cracks in concrete beams can be in the form of flexural cracks, web shear cracks, flexure-shear cracks, torsion cracks, bond cracks. The failure that occurs in the beam has a close relationship with the pattern of cracks formed. Cracks that occur in the beam must be repaired so that the damage does not get worse and efforts to strengthen the structure to ensure it remains saf

    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Studi kasus dilakukan pada proyek perumahan di Jalan Kecipir Kota Palangka Raya dengan pembiayaan dari KPR BNI. Penelitian ini bertujuan untuk mengetahui faktor-faktor apa saja yang menjadi penyebab utama keterlambatan pada proyek perumahan di Jalan Kecipir Kota Palangka Raya dan bagaimana melakukan aksi untuk mengatasi keterlambatan tersebut. Penelitian ini merupakan penelitian kualitatif dan kuantitatif dengan pendekatan deskriptif. Subjek penelitian terdiri dari owner proyek, staf administrasi, pengawas lapangan, serta beberapa tukang. Instrumrn penelitian menggunakan kuesioner yang disebarkan secara langsung kepada responden. Analisis data menggunakan Metode House Of Risk yang berfungsi untuk menganalisa data penyebab keterlambatan. Berdasarkan hasil analisis dengan menggunakan Metode House of Risk (HOR), ditemukan bahwa tiga penyebab utama keterlambatan pada proyek perumahan KPR-BNI di Jalan Kecipir Kota Palangka Raya adalah adanya kenaikan harga bahan dan material, pekerjaan tambahan, dan perkembangan ekonomi.

    The purpose of this research is to find out the influence of depth beam to bending and shear capacity on simple beam. This research is using single span with length 6 m as a model.The width of the beam is constant (20 cm) and the depth of the beam have variation from 30 cm, 35 cm and 40 cm respectively.The load acting on the beamis selfweight, concentrated force and combination between selfweight and concentrated forced. The result of this research has showed that increasing of depth of beam will increase the bending and shear capacity. For the beamsthatonly account upon selfweight, increasing the depth ofbeam by 5 cm and 10 cm will increase the value of bending capacity 16.30% and 32.92% respectively. The beam thatonly accounts upon concentrated force, increasing the depth of beam by 5 cm and 10 cm will increasethe value of bending capacity36.11% and 77.78% respectively. The beamsthataccount upon selfweight and concentrated force, increasing the depth of beam by 5 cm and 10 cm will increase the value of bending capacity30.78% and 64.37% respectively. The beamsthat only account upon selfweight have the same shear capacity for all type of beam. The beamswhich only account upon concentrated force, increasing the depth of beam by 5 cm and 10 cm will increase the shear capacity value16.58% and 33.24% respectively. The beamsthat account upon selfweight and concentrated force, increasing the depth of beam by 5 cm and 10 cm will increase the value of shear capacity 11.08% and 21.12% respectively
