Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Global view and sustainable management of agricultural land in Slovenia
Get PDFKmetijska zemljišča so tako kot v preteklosti še vedno izpostavljena različnim oblikam degradacij. Problematika ohranjanj kakovostnih oz. rodovitnih tal predstavlja velik problem na ravni celotnega sveta. V Sloveniji je še posebej izrazita pozidava najboljših kmetijskih zemljišč na ravninskih območjih. Poleg pozidave, pa se letno povečuje še površina kmetijskih zemljišč v zaraščanju. Površin kmetijskih zemljišč, še posebej njiv in vrtov je na prebivalca zelo malo, pri čemer Slovenija izrazito izstopa od povprečja Evropske unije (EU-27). Stihijska izguba kmetijskih zemljišč že predstavlja velik primanjkljaj zagotavljanja rastlinske proizvodnje in s tem povezane prehranske varnosti slovenskega prebivalstva. V sklopu raziskave smo preučili potencialno rabo zemljišč Slovenije, glede na izbrane pedogeografske dejavnike (nadmorska višina, naklon, vrednost talnega števila). Raziskavo smo nato nadgradili in preučili še dejansko rabo zemljišč, prav tako glede na znane pedogeografske dejavnike in pri tem izpostavili pozidana in sorodna zemljišča ter kmetijska zemljišča v zaraščanju. Raziskava obsega tudi izračune površin potencialne rekultivacije kmetijskih zemljišč v zaraščanju, travniških površin in gozdnih zemljišč v rabo njive in vrtovi. Pri rekultivaciji kmetijskih zemljišč v zaraščanju in gozdnih zemljišč je bilo zaradi omejitvenih dejavnikov glede možnosti rabe njiv in vrtov izbrana kot nadomestna možnost potencialne rekultivacije v travniške površine.Agricultural land as in the past are still exposed to various forms of degradation. The problem of maintaining high quality and fertile soil is a major problem in the entire world. In Slovenia, it is particularly pronounced sealing of the best agricultural land in lowland areas. In addition to sealing it annually increases the areas of agricultural land abandoned. The areas of agricultural land, especially arable land and gardens per capita is very low, while Slovenia distinctly stands out from the average of the European Union (EU-27). Uncontrolled loss of agricultural land is already a huge deficit of providing crop production and related food security of the Slovenian population. During the research we examined the potential use of land Slovenia, depending on the selected pedogeographical factors (altitude, slope, the value of the floor number). The survey was then upgraded and explore more effective use of land, also based on the known pedogeographical factors and emphasizing the role of built-up and related land and agricultural land abandoned. The survey also includes calculations of surface potential recultivation abandoning of agricultural land, grasslands and forest land to arable land use. In the reclamation of agricultural land abandoned and forest land was due to limiting factors on the possibility of the use of arable land and gardens chosen as an alternative potential recultivation in the meadows and grassland
BACK UP POWER SUPPLY FOR CENTRAL HEATING SYSTEM
Get PDFDiplomsko delo opisuje potek načrtovanja pomožnega napajanja centralnega ogrevanja v primeru izpada omrežne napetosti, ki omogoča varno ustavitev sistema. V načrtovanju smo realizirali module, potrebne za delovanje sistema in na razvojni ploščici preizkusili delovanje. Opisani so sestavni elementi v načrtovanju in njihovo delovanje ter vloga v vezju. Krmilni del bazira na platformi Arduino. Razvita programska koda določa način napajanje črpalke glede na stanje digitalnih in analognih vhodov.The thesis describes the course of auxiliary power planning of central heating in case of network voltage loss, which allows safe shutdown. In the course of planning we realized the modules necessary for the system operation, and we tested the operation on the development plate. The constituent elements in the planning, its operation, and its role in the circuit are described. Control module is based on the Arduino platform. The developed programming code determines the way of the pump power supply according to the state of digital and analog inputs
Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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
