Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Formulasi Kopi Ginseng (Pfaffia paniculata) Cepat Saji dengan Komposisi Kopi Robusta Pupuan, Dampit dan Lampung ,
Full text linkSebagai negara penghasil kopi terbesar no 4 di dunia, harga biji kopi Indonesia
sangat tergantung pasaran luar negeri. Maka perlu upaya diversifikasi dan
pengembangan produk sekunder, sehingga memberikan nilai tambah, membuka
lapangan kerja, pengembangan industri terkait dan peningkatan konsumsi dalam
negeri. Salah satu diversifikasi produk adalah kopi ginseng cepat saji (instant).
Citarasa produk sangat dipengaruhi oleh asal (origin) dan mutunya. Perlu
pengujian formulasi kopi ginseng cepat saji menggunakan uji organoleptik
kesukaan (hedonic test). Biji kopi diambil dari kopi robusta Bali (Pupuan), kopi
Jawa (Dampit) dan kopi Lampung sebagai pusat produksi kopi di Indonesia.
Sedangkan bahan komposit diambil dari jenis ginseng Brazilia (Pfaffia
paniculata). Ginseng jenis ini umur panen akarnya lebih cepat yaitu hanya 5 – 6
bulan dibanding ginseng dari Korea atau China (jenis Panax spp) yang dipanen
setelah umur 3 - 4 tahun. Produk dibuat cepat saji (Instan) dengan sistem
aglomerasi dengan alat kristalisator. Penelitian disusun menurut rancangan acak
kelompok (RAK) dengan faktor A asal kopi dan faktor B jumlah ginseng. Hasil
penelitian menunjukkan formulalsi tergantung asalan (origin) dan mutu bahan
baku dan khusus (formulasi yang paling baik) untuk kopi Lampung dengan
proporsi : 93 kopi dan 7 ginseng, Dampit: 97 kopi dan 3 ginseng atau 91 kopi dan
9 ginseng, Bali : 99 kopi dan 1 ginseng atau 91 kopi dan 9 ginseng. Formulasi
untuk peminum kopi : 97 kopi dan 3 ginseng, Formulasi bukan peminum kopi : 91
kopi 9 ginseng. Harga dasar produk yang paling disukai konsumen, untuk kopi
Dampit Rp 19.964,00 kopi Lampung Rp 30.225,06, dan kopi Bali Rp 14.516,67.
Riset lanjutan perlu dilakukan formulasi menggunakan bahan asalan arabika,
robusta daerah lain atau blending arabika – robust
APLIKASI PEWARNA KULIT BUAH DUWET (SYZYGIUM CUMINII) PADA YOGURT DAN SIRUP
No full textPerkembangan ilmu pangan, ilmu gizi dan kedokteran telah banyak
menginformasikan bahaya bahan-bahan sintetik dalam pangan. Hampir semua produk
dipasaran menggunakan pewarna dan diperkirakan 90% zat pewarna sintetik,
padahal hasil penelitian pada hewan percobaan dipastikan bahwa pewarna sintetik ini
bersifat toksik dalam jangka panjang. Pewarna alami merupakan salah satu jawaban
menciptakan suatu produk pewarna yang aman bagi kesehatan. Buah duwet
(Syzygium cumini) merupakan salah satu buah penghasil pigmen antosianin terutama
pada kulitnya. antosianin inilah yang akan diekstrak dan dibuat dalam bentuk sediaan
pewarna cair dan bubuk, kemudian diaplikasikan pada produk pangan. produk pangan
yang dipilh adalah yogurt dan sirup yang mempunyai sifat keasaman tinggi.
penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi sediaan pewarna
alami cair maupun bubuk dari kulit buah duwet yang ditambahkan pada yogurt dan
sirup terhadap warna, pH dan kadar brix, stabilitas warna dan pH selama rentang
penyimpanan dan penerimaan konsumen terhadap produk
Penelitian dilakukan dengan penambahan pewarna alami cair dan bubuk pada
yogurt dan sirup. Penambahan pewarna cair pada yogurt sebesar 0, 2,5, 5 dan 7,5%,
pewarna bubuk sebesar 0, 1, 2, dan 3% dan pewarna sintetik 0,06%. penyimpanan
dilakukan pada suhu dingin (refrigerant) selama rentang 18 hari. Untuk sirup
konsentrasi penambahan pewarna cair sebesar 0, 4, 5, dan 6%, pewarna bubuk
sebesar 0, 3, 4, dan 5% dan pewarna sintetik sebesar 0,03%. Penyimpanan dilakukan
pada suhu dingin (refrigerant) dan suhu ruang selama 84 hari. pengujian dilakukan
dengan mengamati pH, warna dan organoleptik untuk hari pertama, selanjutnya
diamati perubahan warna dan pH selama rentang penyimpanan.
Hasil penelitian menunjukkan penambahan pewarna mempengaruhi pH dan
warna, semakin besar konsentrasi penambahannya semakin tinggi pH dan warna yang
dihasilkan, namun perbedaanya tidak terlalu besar. Penyimpanan yogurt rentang 18
hari pada suhu dingin (refrigerant) sedikit mempengaruhi perubahan pH dan warna.
Secara umum pewarnaa bubuk lebih stabil dibanding pewarna cair. Penyimpanan
sirup rentang 84 hari pada suhu dingin dan suhu ruang mempengaruhi perubahan pH
dan warna. Pada sirup penyimpanan suhu dingin lebih menstabilkan pH dan warna
sirup dibanding suhu ruang. Masing-masing perubahan tersebut telah mempengaruhi
stabilitas antosianin yogurt dan sirup. Pada uji organoleptik kesukaan pada yogurt
penambahan pewarna cair yang paling disukai adalah konsentrasi 7,5%, untuk
penambahan pewarna bubuk yang paling diaukai adalah konsentrasi 3%, sedangkan
pada sirup konsentrasi 6% untuk pewarna cair, pewarna bubuk adalah 5
Variations on the Author
Full text link“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 linkWe 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
Full text linkWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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
