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
Effects of Different Irrigation Levels and Nitrogen Fertilization on Some Physiological Indicators of Potato
Full text linkWater and nitrogen are widely used agricultural inputs in potato production areas. However, the excessive and inappropriate use of these significant inputs may lead to the rapid depletion of water resources and inappropriate nitrogen leakage. In potato production, insight into the effects of water and nitrogen on the physiological properties will help to overcome these difficulties. This study was therefore conducted to determine the effects of different nitrogen and irrigation levels on the physiological (photosynthesis rate, leaf area index, leaf chlorophyll content, and leaf temperature) characteristics of potato. Field experiments were conducted during the 2021-2022 and 2022-2023 primary potato cropping seasons to select the suitable combination of irrigation and fertilization levels for potato production in the Nigde Province of the Central Anatolia Region of Turkey. Employing a factorial design, the study encompassed six nitrogen fertilization rates and three irrigation levels. Measurements were systematically recorded at five distinct intervals (40, 50, 60, 70, and 80 days) post-emergence. The outcomes underscored that nitrogen treatments augmented physiological traits, manifesting in heightened photosynthetic rates, chlorophyll content, and leaf area indices, barring leaf temperature, in comparison to the control group (devoid of nitrogen treatments). Full irrigation (I1) yielded the utmost values for both photosynthesis and leaf area index, with I1N3 (full irrigation and intermediate nitrogen supply) was identified as the most efficacious treatment for these parameters. This study identifies the most appropriate nitrogen and irrigation application for optimum physiological yield of the potato for crop producers. However, it is important to note that the study focused solely on one commercial potato cultivar (Agria), and further research on various potato cultivars is recommended for more conclusive results.Scientific Research Project Office (BAP) of Nigde Omer Halisdemir University [TGT 2021/8-BAGEP]; Ayhan Sahenk Foundation; [YOK 100/2000]This research was funded by the Scientific Research Project Office (BAP) of Nigde Omer Halisdemir University (grant number TGT 2021/8-BAGEP).

Feasibility Analysis of Multi-hop Underwater LoRa Networks: an Experimental Approach
No full textreservedIn this thesis, the results of a series of measurements performed to analyze the transmission capabilities of LoRaWAN technology for underwater (transmitter-receiver) transmission are presented. Tests were carried out on communication between Arduino MKR WAN boards using the multi-hop method. In laboratory tests, data transfer was observed by creating double, triple and quintet nodes and focusing on the transmitter and receiver mechanism. Field tests were carried out in the Piovego Canal. During these tests, the transmitting node was sent underwater, and based on this, the data obtained by the receiving node from the transmitting node and the RSSI values of the receiving node were analyzed according to the amount of depth under water. Accordingly, the results obtained show that LoRaWAN transmitters can be used in all those conditions where they are expected to be partially or completely submerged under still water. As a result of this study, it can play an important role in the use of surface marine sensor networks in the context of the Internet of Underwater Things (IoUT) in general
