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

No full textThe purposes of this study were to analyze: 1) the constitution and characteristics of sludge, solid sludge and sludge flour derived from Biogas Unit (BGU); 2) the influence of organic sludge liquid on the percentage of organic and crude protein content of the BGU organic sludge (BGUOS). The methods used in the study were observation and randomized controlled trial experiments. Data derived from field study were analyzed descriptively while data derived from experiments were analyzed using variance analysis. Differences were shown using the smallest significance-p test with CI 95%. The results showed that organic sludge constitution were odious, the organic sludge was clotting after drying process. In addition it became powder as soft as bran after dried, powdered and brooded. The experiment showed that the composition of BGUOS liquid gave influence to the amount of organic content and crude protein in the powder constitution of BGUOS. The fifth treatment brought the optimum percentage of the organic content and crude protein. The research concluded that BGUOS constitution was detestable in its form of sludge, however it could be transformed into bran constitution by drying and brooding treatment. The optimum amount of organic content and crude protein of BGUOS bran were gained by using 5th treatment. The research suggest it is necessary to maintain BGUOS on the basis of local technology and to study the application of BGUOS solid powder or bran as fish and livestock feed.

No full textPeranan polen trap dari bahan bahan plastik dan logam terhadap
peningkatan produksi tepung sari lebah adalah salah satu teknologi yang belum
terungkap secara rinci dan perlu diamati agar produksi perlebahan dapat
ditingkatkan secara pasti. Tujuan penelitian adalah pertama untuk mengetahui
jumlah tepung sari yang dipanen oleh lebah pekerja, kedua untuk mengetahui
jumlah lebah pekerja yang memanen polen per menit dan ketiga untuk
menentukan bahan polen trap yang terbaik. Metode yang dipergunakan adalah
metode percobaan. Variable yang diukur adalah 1). berat polen, 2). jumlah lebah
pekerja yang membawa polen perhari permenit.
Hasil percobaan menunjukkan bahwa polen trap yang terbuat dari plastik
dan logam masing-masing menghasilkan polen sebanyak 5,13 + 1,942 g/menit
dan 13,56 + 2,128 g/menit. Adapun jumlah lebah yang memanen polen adalah
7,85 + 2,063 ekor.dan 12,933 + 2.504 ekor. Polen trap yang dapat digunakan
untuk memanen tepung dapat dibuat dari plastik maupun logam.
Berdasarkan uraian di atas dapat disimpulkan bahwa kemampuan polen
trap plastik maupun logam adalah sama. Saran pertama adalah pembuatan polen
trap sebaiknya dicari plastik warna gelap atau diberi warna terlebih dahulu
sebelum digunakan, sedangkan yang dari logam disarankan lubang masukan lebah
harus halus.

THE ROLE OF POLLEN TRAP OF PLASTICAL SYNTHETIC AND
METAL TO INCREASE BEE POLLEN PRODUCT
Abstract
The role of pollen trap of plastical synthetic and metal materials to
increase bee pollen product is one of technology which not yet been expressed in
detail and require to perceive to bee production can be improved surely. Target of
research are first to know the amount of pollen harvested by worker bee, Secondly
are to know the amount of worker bee which harvesting polen per minute and
third to determine materials of best pollen trap. Method the utilized is experiment.
Variable of the measured are 1). weight of bee pollen, 2). amount of worker bee
bringing pollen perday of permenit
The result of experiment indicate that made pollen trap plastical and metal
each yield pollen grain counted 5,13 + 1,942 g/minute and 13,56 + 2,128g/minute. As for amount of bee which harvesting polen are 7,85 + 2,063 ekor and
12,933 + 2.504 tail. Pollen Trap able to be used to harvest flour can be made of by
metal and also plastic.
To breakdown of above can be concluded that ability of plastic pollen trap
and also metal is same. First suggestion are making of pollen trap better look for
by dark colour plastic or given by colour beforehand before used, while which
from metal suggested by bee input hole have to refine

No full textVariations 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
