Full text link53 HalamanKawasan Hutan Lindung Gunung Sibuatan terletak di Kecamatan Merek,
Kabupaten Karo, Sumatera Utara. Di dalamnya terdapat banyak jenis tumbuhan,
salah satunya adalah kantung semar. Penelitian Keanekaragaman Kantung Semar
(Nepenthes sp) dilakukan pada bulan Juli hingga Agustus 2020. Penelitian ini
bertujuan untuk mengetahui keanekaragamannya. Lokasi penelitian ditentukan
dengan metode purposive sampling, observasi dilakukan dengan metode transek
dan survei. Ada 3 spesies Nepenthes, yaitu N. spectabilis, N. pectinata dan N.
spectabilis x N. pectinata. Nepenthes yang dominan di lokasi penelitian adalah N.
pectinata dengan indeks nilai penting 101.06%. Indeks Keanekaragaman
Nepenthes sp dengan nilai 0,74 tergolong rendah. Indeks keseragaman nepenthes
sp dengan nilai 0.67 tergolong tinggi. The Mount Sibuatan conservation Area is located in Brand District, Karo
Regency, North Sumatera there are many types of plant diversity in that area, one
of which is Nepenthes sp the research of diversity of Nepenthes sp was conducted in
July up to August 2020. This study aims to determine the diversity of Nepenthes
spp. In The method used was transect and survey methods. Results showed that here were
3 Nepenthes species, namely N. spectabilis, N. pectinata and N. spectabilis x N.
pectinata The dominant Nepenthes was N. pectinata with an important value
index of 101.06%. The diversity index of Nepenthes sp 0.74 is classified as low.
Nepenthes sp uniformity index with a value of 0.67 is classified as hi
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
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
Formulation Of Instant Functional Collagen Drink With Date Seeds Coffee (Phoenix dactylifera) And Spices (Ginger, Cinnamon, Cardamom, Clove) Using The D-Optimal Mixture Design Method
Full text linkThe functional food trend has grown rapidly since the Covid-19 pandemic, including products made from natural ingredients like herbal collagen drinks. This research aims to develop an optimal collagen drink formulation by adding date seed coffee with ginger, cinnamon, cardamom, and cloves as antioxidants to optimize collagen function.Optimization was carried out using the Design Expert-13 device with the optimization response of antioxidant activity (mg TE/100g) and water content (%). The results showed that the optimal formulation consisted ofdate seed coffee 35.57%; hydrolyzed collagen 25%; and spice mixture (ginger, cinnamon, cardamom, cloves) of 39.432% with a desirability value of 0.741.The optimal product was then instantiated using the spray drying method and compared with commercial products without instantiation and collagen addition.The optimal product has an IC50 antioxidant activity of 743.86 ppm and total phenols of 187.23 mg GAE/100g), with a water content of 3.35%, hygroscopicity of 7.76%, bulk density of 0.488 g/mL, and a dissolution time of 23.32 seconds. The results of the hedonic test on the optimal sample as a whole from 100 panelists were “rather like†to “like†with an average value of 3.17 with the most preferred attributes being the consistency and aroma of spices
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
