Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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 PDFWe 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
PENGARUH PENGETAHUAN DAN SIKAP ORANG TUA TERHADAP SWAMEDIKASI OBAT DEMAM PADA ANAK-ANAK
No full textSwamedikasi biasanya dilakukan untuk penanggulangan secara cepat dan efektif keluhan yang tidak memerlukan konsultasi medis, mengurangi beban pelayanan kesehatan pada keterbatasan sumber daya dan tenaga, serta meningkatkan keterjangkauan pelayanan kesehatan untuk masyarakat yang jauh dari puskesmas. Tujuan penelitian ini untuk mengetahui pengaruh antara pengetahuan dan sikap orang tua terhadap swamedikasi obat demam pada anak-anak.Penelitian ini merupakan jenis penelitian analisis observasional, dengan pendekatan cross sectional. Populasinya adalah warga Dusun Cepor, Sendangtirto, Berbah, Sleman yang memiliki anak usia 1sampai 12 tahun yang berjumlah 172 KK, dan diperoleh sampel sebanyak 62 sampel. Pengumpulan data menggunakan kuesioner dan analisis data menggunakan uji bivariat dan regresi logistik berganda.Berdasarkan analisis data diperoleh hasil regresi logistik terdapat pengaruh positif dan secara statistik signifikan antara pengetahuan orang tua dengan swamedikasi obat demam pada anak-anak, dimana orang tua dengan tingkat pengetahuan tentang obat yang baik memiliki tingkat swamedikasi yang baik dan tinggi (( 28,464 x lebih besar daripada yang pengetahuan sedang atau kurang ( OR= 28,464 ; CI 95% 3,087 sampai dengan 262,467; p = 0,003)) dan tidak terdapat pengaruh positif dan secara statistik signifikan antara sikap orang tua dengan swamedikasi obat demam pada anak-anak, dimana sikap orang tua mempunyai kemungkinan lebih tinggi 3,049 x lebih besar dari pada yang tidak mempunyai sikap (OR= 3,049; CI 95% 0,320 sampai dengan 29,012; p = 0,332). Nilai Nagelkerke R Square sebesar 0,596 memiliki pengertian bahwa 59,6 persen swamedikasi obat demam pada anak-anak tidak dipengaruhi secara bersama-sama oleh variabel pengetahuan orang tua dan sikap orang tua, dan sisanya dipengaruhi oleh faktor yang lainnya.
FORMULASI VANISHING CREAM MINYAK ATSIRI RIMPANG JAHE (Zingiber officinale Roxb) DAN UJI AKTIVITAS REPELAN TERHADAP NYAMUK Aedes aegypti BETINA
Get PDFThe essential oil of Ginger rhizome is a natural subtance which has been proved
to have a repellent effect to the mosquito. The aim of this study was to know the effect of
this subtance/these substances in vanishing cream dosage forms as repellant to the
female Aedes aegypti mosquito. The essential oil of Ginger rhizome was isolated with
aqueous vapor destillation. Then the result was determined for its physical properties,
these were: viscosity, adhesivity, spreadibility and its repellant effect to mosquito as
well. The vanishing cream formulation, containing variation of the essential oil
concentration were prepared, these were: FI (formulation I), FII, FIII, FIV and FV,
containing 6,25%, 12,5%, 15%, 20% and 25% of the essential oil respectivity. Each
formulas were tested for their physical properties were viscosity, adhesivity,
spreadibility and its repellant effect to mosquito as well. The datas were analyzed.
Statistically using SPSS version 16 with Kolmogorov-Smirnov and continued with the
t-test (Mann-Whitney) (=0,05). The result showed that the duration of the adhesivity
of FI was the longest than the others (1,37±0,15 minutes); the spreadibility of the FI
was widest (71,69±1,76 mm2
), and the viscosity was the largert than others (27±0 cps).
The repellant capasity of the FV was the longest than the others (47,3±1,80 minutes)
Formulasi dan Uji Antijerawat Gel Ekstrak Etanol 70% Buah Belimbing Wuluh (Averrhoa Bilimbi Linn.) terhadap Bakteri Propionibacterium acnes
Get PDFABSTRACT Belimbing wuluh fruit known have flavonoids that has a function as natural anti bacterial for acne treatmeant. To easer in using it, so it formulated in the form of gel. The aims of research was to know the influence of variation concentration ethanol extract 70% belimbing wuluh fruit to physical characteristic of gel and antibacterial activity of Propionibacterium acnes which a bacteria causes acne. Belimbing wuluh fruit extract was obtained by maceration. Extract formulated in the form of gel with variation concentration 4,17%w/v, 8,33% w/v, 12,5%w/v, 16,67%w/v, and 20,83%w/v. Antibacterial activity test was conducted by cup plate technique difusion methode and physical characteristic test covered organoleptic test, spreadibility test, and adhesivity test. The result of antibacterial test and physical characteristic test were analyzed statistically using Kruskall Wallis test and Mann Whitney test with 95% level confidence. The result of research showed that with an increasing concentration of extract could affect physical characteristic of gel and will increase antibacterial activity. The higher concentration extract, the color of gel obtained more concentrated, pH of gel be acid, decreasing adhesive power, spread power obtained smaller and inhibition diameter obtained bigger. The result of research obtained that formula 2 was a good formula with pH value 5, average adhesive power was 4,63 seconds ± 0,57, average spread power was 11,34 cm2 ± 0,44 and average diameter obstruent was 5 mm ±1,41. Based on the research could be concluded that gel extract ethanol 70% belimbing wuluh (Averrhoa bilimbi Linn) fruit had antibacteria activity against Propionibacterium acnes. Minimal concentration which could inhibit growth that bacteria found at concentration 5% and formula which had a good physical characteristic at formula 2.Keywords : Gel, Etanolic extract 70%; Averrhoa Bilimbi Linn, Propionibacterium acnes
