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
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

Diversitas dan Distribusi Alga Merah (Rhodophyta) di Perairan Pulau Ternate
Full text linkRed algae (Rhodophyta) are low-level plants that generally grow attached to certain substrates such as coral, mud, sand, rocks and other massive objects. This type of algae take nutrients from the substrate by diffusion through the walls from its thallus. This alga prefers habitat of clear waters that have substrate base of coral, dead coral, volcanic rocks or massive objects. Red algae can be found in intertidal, subtidal to coastal areas with strong waves and currents as well as in mangrove area. This study aims to determine the diversity and distribution patterns and associations of red algae in seagrass ecosystems and coastal coral reefs of Ternate Island. The method used in this study is a descriptive method with sampling by line-transect quadrat (1x1 meter). The sampling locations were divided into three stations. Data were analyzed descriptively and the number of red algae (Rhodophyta) found at each station was included in a distribution map based on depth and density index. The results showed that the total number of individuals found at the three stations was 33, where ST II dominated with 12 with an average of 3 individuals per depth. Distribution of individuals per depth at ST II was highest at a depth of 10 m with 4 individuals, followed by a depth of 5 and 15 m each with 3 individuals, a depth of 25 m was 1 individual, and no individual was found at 20 m depth. Substrate type at a depth of 10 m was dominated by coral and sandy fractures that could support well the growth and development of red algae. Alga merah (Rhodophyta) merupakan tumbuhan tingkat rendah yang umumnya tumbuh melekat pada substrat tertentu seperti pada karang, lumpur, pasir, batu dan benda keras lainnya. Salah satu alga yang penting untuk diteliti adalah alga merah (Rhodophyta). Jenis alga ini mengambil nutrisi dari substrat secara difusi melalui dinding thallus-nya sedangkan habitatnya adalah perairan jernih yang mempunyai substrat dasar batu karang, batuan vulkanik dan benda-benda yang bersifat massive yang berada di dasar perairan. Alga merah dapat ditemukan pada daerah intertidal, subtidal sampai daerah tubir dengan ombak besar dan arus deras serta di hutan mangrove. Penelitian ini bertujuan untuk mengetahui diversitas dan pola sebaran serta asosiasi alga merah pada ekosistem lamun dan terumbu karang pesisir Pulau Ternate. Metode yang digunakan pada penelitian ini adalah metode deskriptif dengan pengambilan sampel secara line transek kuadrat (1x1 meter). Lokasi pengambilan sampel dibedakan menjadi tiga stasiun. Data dianalisis secara deskriptif dan jumlah alga merah (Rhodophyta) yang ditemukan pada setiap stasiun di tuangkan dalam peta distribusi berdasarkan data kedalaman serta indeks kepadatannya. Hasil penelitian menunjukkan bahwa total individu yang ditemukan pada ketiga stasiun adalah sebanyak 33, dimana pada ST II mendominasi dengan jumlah 12 dengan rata-rata perkedalaman adalah 3 individu. Sebaran individu perkedalaman ST II terbanyak pada kedalaman 10 m sebanyak 4 individu, diikuti kedalaman 5 dan 15 m masing-masing adalah 3 individu, kedalaman 25 m sebanyak 1 individu, sedangkan pada kedalaman 20 m tidak ditemukan. Tipe pada kedalam 10 m didominasi oleh patahan karang dan berpasir dimana pada kondisi substrat tersebut dapat mendukung pertumbuhan dan perkembangan alga merah.

Full text linkLindur mangrove fruit (Bruguiera gymnorrhiza) which is traditionally processed into cakes, cakes, mixed with rice, or eaten directly. Food sourced from the Coastal Ecosystem, namely the mangrove fruit of the Lindur type (Bruguiera gymnorrhiza) contains energy and carbohydrates that are pretty high, even surpassing the various types of food sources of carbohydrates commonly consumed by the community such as rice, cassava corn, or sago. The study aims to provide food-making training on Maitara Island, North Tidose District, Tidore Islands City. The service method used is Counseling and Training and Courses in food processing from Lindur fruit. The results showed that Lindur fruit has an average length of 27 cm with an average weight of 45 g. The results of the chemical analysis of lindur fruit were 73.756% water content, 1.246% fat content, 1.128% protein, 23.528% carbohydrates, and 0.342% ash content. The anti-nutritional content of HCN is 6.8559 mg and tannin is 34.105 mg. The manufacturing process consists of several stages, namely collecting mangrove fruit, handling mangrove fruit in the form of peeling, soaking then steaming and grinding to become flour to making various types of snacks from mangrove fruit, namely mangrove fruit fritters and mangrove fruit crackers.
