Analisis kesuburan perairan di Sungai Desa Kotawaringin Kabupaten Bangka berdasarkan indeks nygaard
No full textSungai Kotawaringin merupakan sungai yang sering imanfaatkan dengan berbagai aktivitas antropogenik, yang dapat menyebabkan perubahan pada faktor-faktor fisika, kimia dan biologis suatu perairan. Salah satu parameter biologi yang
berfungsi sebagai indikator kualitas air adalah fitoplankton. Komposisi dan kelimpahan fitoplankton di perairan menentukan kesuburan dengan perhitungan
indeks Nygaard. Penelitian ini bertujuan untuk mengetahui kualitas perairan, komposisi dan kelimpahan fitoplankton, hubungan kelimpahan fitoplankton dengan kualitas air, dan tingkat kesuburan perairan berdasarkan Indeks Nygaard.
Metode yang di gunakan adalah metode purposive sampling, dengan pengambilan sampel fitoplankton, pengambilan parameter lingkungan, identifikasi fitoplankton
dan analisis data fitoplankton dan kualitas air. Kualitas perairan yang di dapatkan pada stasiun I, II, dan III adalah Rata-rata suhu 26,8-27,6˚C, pH 5-6,7, DO 4-6,5 mg/L, TSS 15,5-33,5 mg/L, Kecepatan arus 0,03-0,14 m/s, kedalaman 7,73-12,8 m, kecerahan 59-85 %, nitrat 0,400-0,700 mg/L, dan fosfat <0,0214-0,247 mg/L. Komposisi fitoplankton keseluruhan sebanyak 34 jenis dari 9 kelas. Fitoplankton
stasiun I, II dan III secara berturut-turut dengan komposisi 24 jenis dan kelimpahan 6.486 – 10.261 ind/L, komposisi 20 jenis dan kelimpahan 4.063-5.874 ind/L, serta komposisi 20 jenis dan kelimpahan 4.466-7.667 ind/L. Kesuburan
perairan menggunakan Indeks Nygaard (In) menunjukkan kesuburan yang sangat ringan atau mesotrofik yaitu pada stasiun I, II dan III berkisar 2,25-2,7, 1,67-2,33,
dan 2,0-2,33
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
