    Konsentrasi memegang salah satu peran utama bagi peserta pelatihan untuk dapat menerima  materi bahan ajar  yang diajarkan oleh instruktur. Salah satu bentuk upaya meningkatkan konsentrasi tersebut adalah dengan Latihan aerobik. Adapun dalam penelitian ini mempunyai tujuan untuk membuktikan adanya pengaruh Latihan aerobik terhadap tingkat konsentrasi proses belajar pada peserta pelatihan terutama bidang ekspor di lembaga pendidikan Anto Sejahtera Indonesia. Dalam hal ini teknik sampling yang digunakan menggunakan teknik purposive sampling. Yaitu khusus peserta yang mengikuti pelatihan dengan materi khusus bidang ekspor. Dalam penelitian ini terdiri dari dua Kelompok yaitu kelompok perlakuan dengan latihan dan kelompok kontrol tanpa diikuti latihan. Masing-masing kelompok berjumlah 15 responden. Sebelum dilakukan latihan aerobik baik kelompok perlakuan dan kontrol dilakukan Stroop tes. Untuk kelompok perlakuan setelah dilakukan latihan aerobik para peserta di tes kembali menggunakan Stroop tes. Sedangkan kelompok kontrol juga mengikuti Stroop tes. Metode analisa statistik yang digunakan menggunakan  uji paired t test dan uji t independent . Hasil penelitian menunjukan terdapat perbedaan antara kelompok kontrol dan kelompok perlakuan. Hasil perhitungan selisih nilai rata-rata menunjukan kelompok perlakuan bernilai 76,6 sedangkan untuk kelompok kontrol bernilai 40,47. Perbedaan hasil ini menunjukan bahwa kelompok perlakuan nilai rata-ratanya lebih tinggi dibanding kelompok kontrol. Disamping itu dengan uji independent t tes dihasilkan nilai signifikansi sebesar 0,00. Dengan demikian dapat disimpulkan bahwa terdapat perbedaan antara kedua kelompok tersebut. kelompok perlakuan lebih efektif daripada kelompok kontrol

    Identifikasi Sifat Selektifitas Jaringan Biologi pada Spektrum Near-Infrared dengan Citra menggunakan Hukum Beer-Lambert

    ABSTRAKSinar near-IR memiliki sifat selektifitas berupa koefisien atenuasi. Metode lain untuk melihat sifat selektifitas adalah menggunakan citra. Untuk menghasilkan citra tersebut digunakan fungsi ketebalan berdasarkan hukum Beer Lambert. Material yang digunakan adalah daging, kulit dan tulang dari ayam. Tujuan penelitian ini adalah menghasilkan citra berdasarkan fungsi ketebalan untuk mengetahui sifat selektifitas antara material. Hukum Beer Lambert menyatakan bahwa nilai intensitas akan teratenuasi tergantung dari fungsi eksponensial koefisien atenuasi dan ketebalannya. Dengan melinierkan persamaan tersebut, maka didapatkan nilai ketebalan suatu material. Hasil penelitian menunjukan bahwa dengan menghitung nilai fungsi ketebalan, maka dapat ditampilkan citra. Pada citra tersebut antar material menunjukan kontras rasio yang berbeda-beda. Sumber near-IR yang digunakan pada panjang gelombang 780 nm dan 980 nm. Hasil menunjukan bahwa panjang gelombang 980 nm menunjukan sifat selektifitasyang lebih baik. Kata kunci: selektifitas, koefisien atenuasi, beer lambert, kontras rasio, pencitraan. ABSTRACTNear-IR rays have accuracy properties in the form of an attenuation coefficient. Another method to see the nature of selectivity is to use imagery. A thickness function based on Beer-Lambert's law is used to produce this image. The materials used are meat, skin, and bones from chickens. This research aims to create images based on the thickness function to determine the nature of selectivity between materials. Beer-Lambert's law states that the intensity value will be attenuated depending on the exponential function of the attenuation coefficient and thickness. By linearizing this equation, we get the thickness value of a material. The research results show that an image can be displayed by calculating the thickness function value. In this image, the materials show different contrast ratios. Near-IR sources are used at wavelengths of 780 nm and 980 nm. The results show that the wavelength of 980 nm leads to better selectivity properties.Keywords: selectivity, attenuation coefficient, Beer-Lambert law, contras ratio, Imaging

    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

    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

    Get PDF
    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

    Get PDF
    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

    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
