Analysis of selected factors impacting changes in the number of brown hare (Lepus europaeus Pall.) in Vojvodina - importance for hunting and hunting tourism
Get PDFПредмет истраживања докторске дисертације представља проблематика флуктуације популације европског зеца (Lepus europaeus Pall.) на територији Војводине, као врсте значајне за ловство и ловни туризам. С обзиром да се ради о изразитом пољопривредном станишту потребно је испитати специфичне односе између станишних услова и лова, односно управљачких фактора, ради оцењивања тренутног статуса ове врсте. Анализа наведене проблематике извршена на основу параметара: пролећна бројност, годишњи одстрела и реалног прираста за период између 1970. и 2020. године. Кроз прикупљање свих доступних података и литературе, као и анализе нових података циљ је био да се изврши преглед газдовања у наведеном периоду и означе главни разлози пада бројности популације. Да би се испитале промене бројности популације дефинисани су фактори и тестирана њихова веза и утицај на промене у бројности. У анализу утицаја укључени су климатски фактори, фактори пољопривредне производње тј. станишта, утицај предатора и одстрела зеца. На основу извршених статистичких анализа препознати су главни проблеми и фактори који имају највећи утицај на промене бројности зеца на простору Војводине. Ово је значајно за ловачке организације које управљају ловиштима у Војводини. Препознавањем фактора и њиховог стварног утицаја на бројност европског зеца сагледани су разлози пада бројности. На основу ових информација дате су препоруке за адекватније управљање популацијом, што је била крајња сврха овог истраживања.Predmet istraživanja doktorske disertacije predstavlja problematika fluktuacije populacije evropskog zeca (Lepus europaeus Pall.) na teritoriji Vojvodine, kao vrste značajne za lovstvo i lovni turizam. S obzirom da se radi o izrazitom poljoprivrednom staništu potrebno je ispitati specifične odnose između stanišnih uslova i lova, odnosno upravljačkih faktora, radi ocenjivanja trenutnog statusa ove vrste. Analiza navedene problematike izvršena na osnovu parametara: prolećna brojnost, godišnji odstrela i realnog prirasta za period između 1970. i 2020. godine. Kroz prikupljanje svih dostupnih podataka i literature, kao i analize novih podataka cilj je bio da se izvrši pregled gazdovanja u navedenom periodu i označe glavni razlozi pada brojnosti populacije. Da bi se ispitale promene brojnosti populacije definisani su faktori i testirana njihova veza i uticaj na promene u brojnosti. U analizu uticaja uključeni su klimatski faktori, faktori poljoprivredne proizvodnje tj. staništa, uticaj predatora i odstrela zeca. Na osnovu izvršenih statističkih analiza prepoznati su glavni problemi i faktori koji imaju najveći uticaj na promene brojnosti zeca na prostoru Vojvodine. Ovo je značajno za lovačke organizacije koje upravljaju lovištima u Vojvodini. Prepoznavanjem faktora i njihovog stvarnog uticaja na brojnost evropskog zeca sagledani su razlozi pada brojnosti. Na osnovu ovih informacija date su preporuke za adekvatnije upravljanje populacijom, što je bila krajnja svrha ovog istraživanja.The subject of the doctoral dissertation research is the problem of fluctuation of the brown hare (Lepus europaeus Pall.) population on the territory of Vojvodina, as a species that has great importance for both hunting and hunting tourism. Given that this is a distinct agricultural habitat, it is necessary to examine the specific relationships between habitat conditions and hunting, or management factors, to assess the current status of this species. The analysis of the mentioned problems was performed based on the following parameters: spring number, annual cull, and real growth for the period between 1970 and 2020. Through the collection of all previously available data and literature, as well as the analysis of new data, the goal was to review the management in this period and identify the main reasons for the population decline. To examine changes in population size, factors were defined and their relationship and impact on changes in numbers were tested. The impact analysis included climatic factors, factors of agricultural production, ie. habitat, predator impact, and hare cull. Based on the performed statistical analyzes, the main problems and factors that have the greatest impact on changes in the number of hares in Vojvodina have been identified. This is important for hunting organizations that manage hunting grounds in Vojvodina. By recognizing the factors and their real impact on the number of brown hares, the reasons for the decline in numbers were considered. Based on this information, recommendations for improving population management were given, which was the ultimate purpose of this research
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

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
