    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

    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

PKS merupakan salah satu komponen yang sangat penting dalam perkebunan kelapa sawit. Secara umum PKS yang dibangun oleh PTPN dalam skala besar, sehingga pembangunan suatu PKS memerlukan biaya yang sangat besar. Hal ini akan menjadi suatu kendala bagi (PIR) untuk memiliki PKS dengan kapasitas besar. "Oleh karena itu sangat diperlukan terobosan barn untuk merancang PKS dalam skala kecil, sehingga terjangkau oleh pengelola PIR. Pada PKS skala kecil yaitu kapasitas (5-;...10) ton TBS/jam diperlukan juga mesin pengolah biji kelapa sawit (Rippel Mill) dengan kapasitas (l-;-2) ton biji sawit/jam. Sehubungan dengan hal ini, penulis telah merancang sebuah mesin pengolah biji kelapa sawit dengan kapasitas 2 ton biji sawit/jam. Hasil perancangan mesin pengolah biji sawit (Rippel Mill) dengan kapasitas 2 ton/jam akan dipaparkan disini secara garis besar, sebagai berikut: Kapasitas Ripple Mill adalah sebesar 1 [ton/jam], Putaran rotor Ripple Mill= 121 [rpm], Daya Motor= 2 [HP], Putaran rotor = 1450 [rpm], Sabuk dan Puli I, Diameter puli penggerak = 65 [mm], Diameter puli yang digerakkan= 130 [mm], Sabuk sabuk V tipe A dengan bahan kulit, Jarak sumbu poros= 260 [mm], Sabuk dan Puli II, diameter puli penggerak = 65 [mm], Diameter puli yang digerakkan = 570 [mm], Sabuk yang digunakan adalah sabuk V tipe A dengan bahan dari sutra dan rami, Jarak sumbu poros = 1140 [mm], Diameter poros transmisi 17 [mm] bahan S55C ( JIS G 4501 ), Diameter rotor as/ poros sebesar 18 [mm] bahan SNC 3 (JIS G 4102), Bahan Spacer Ring FC20 (JIS G 3501) dengan ukuran sebagai berikut: Diameter dalam = 25 [mm], Diameter Naff=35 [mm], Diameter luar= 78 [mm], Diameter lubang baut = 10 [mm], Tebal flange = 15 [mm], Diameter lingkaran baut = 50 [mm], Baut pengikat Spacer Ring dan piringan baut MlO Bahan baut S20C (JIS 302), Diameter minimum rotor bar sebesar 15 [mm] dengan bahan S30C(JIS G4501), Bahan piringan Fc20 (JIS G550) dengan ukuran sebagai berikut: Diameter dalam = 22 [mm], Diameter lingkaran baut= 58 [mm], Diameter lubang baut = 58 [mm], Diameter lingkaran rotor bar dalam = 104 [mm], Diameter lingkaran rotor bar luar = 124 [mm], Diameter lubang rotor bar = 15 [mm], Diameter luar = 154 [mm], Tebal= 15 [mm], Bantalan Ripple Plate Fc20 (JIS G 5501) dengan ukuran sebagai berikut : Jumlah gigi = 15, Lehar akar gigi= 15 [mm], Jari-jari lingkaran dalam Ripple Plate =91 [mm], Jari-jari lingkaran pangkal gigi= 101 [mm], Jari-jari lingkaran luar Ripple Plate= 116 [mm], Bantalan pada poros transmisi, Bantalan B dengan nomor 6204, Bantalan C dengan nomor 6004, Bantalan pada rotor as/ poros, Bantalan A dengan nomor 6004, Bantalan C dengan nomor 6304. Oil palm plantations and palm oil mills (MCC) is still dominated by State-owned plantations in this case is the PTPN., But private estates and plantations for smallholders (NES) also plays a huge role in the development of oil palm plantations inj . MCC is one crucial component in the oil palm plantations. In general MCC PTPN built by a large scale, so that the construction of an MCC requires a very large cost. This will be an obstacle for (PIR) to have the MCC with a large capacity. Hence the new breakthrough is needed to design the MCC on a small scale, so that affordable by managing the PIR. At MCC, the small-scale capacity (5 -:- 10) tons FFB I hour is required also moving machinery oil palm seeds (Rippel Mill) with a capacity of ( 1 -:- 2) tons of seed oil per hour. In this regard, the author has designed a palm seed processing machine with capacity of 2 tons of seed oil per hour The design result seed oil processing machine (Rippel Mill) with a capacity of 2 tons I hour will be presented here in outline, as follows: Ripple Mill capacity is 1 [ton I h], rotor Round Ripple Mill = 121 [rpm], Power Motor= 2 [HP], Round rotor = 1450 [rpm], Belt and Puli I, the driving pulley diameter = 65 [mm], which is driven pulley diameter= 130 [mm], type AV Belt belt with leather, the shaft axis distance= 260 [mm], and Puli II Belt, drive pulley diameter= 65 [mm], diameter pulley driven = 570 [mm], was used Belt V belt type A with materials of silk and hemp, distance axis axis = 1140 [mm], the transmission shaft diameter 17 [mm] material S55C (JIS G 4501), diameter of the rotor shaft at 18 [mm] SNC materials 3 (JIS G 4102), Materials FC20 Spacer Ring (JIS G 3501) with the following size: diameter in= 25 [mm], Diameter Naff= 35 [mm], outer diameter = 78 [mm], bolt hole diameter is 10 [mm], thickness of flange= 15 [mm], bolt circle diameter= 50 [mm], Spacer Ring binder bolts and disc bolts MlO bolt Material S20C (JIS 302), the minimum diameter of the rotor bars at 15 [mm ] with material S30C (JIS G4501), Materials Fc20 plate (JIS G550) with sizes as follows: The diameter of= 22 [mm], bolt circle diameter= 58 [mm], Diameter of bolt holes = 58 [mm], the rotor diameter circle bar in a= 104 [mm], Diameter of outer circle rotor bar = 124 [mm], Diameter hole rotor bar= 15 [mm], outer diameter = 154 [mm], thickness = 15 [mm], Bearing Plate Ripple Fc20 (JIS G 5501) with sizes as follows: Number of teeth = 15, tooth width= 15 [mm], The radius of the circle in Ripple Plate = 91 [mm], the base circle radius of gear= 101 [mm], radius outer circle Ripple Plate = 116 [mm], bearings on the transmission shaft, bearings B with 6204 numbers, bearings C with 6004 numbers, bearings in the rotor shaft, bearings A with number 6004, bearing C with number 6304

    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

    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
