Степова рослинність на території Волинської височини та проблеми її охорони
The purpose of the research was the detailed exploration of the extrazonal prairie areas on the territory of the Volyn highlands. Exclusive prairie species as well as calcareous prairie species are rare and less common in this region. The focus of the research was on performing an inventory of those species on the territory of the Volyn highlands, studying the ecologo-coenotic conditions of their vegetation, discovering the reasons of reduction of population of the species as well as developing the scientific ground for their protection. Following the monitoring activities around the Volynski highlands the few areas of prairie vegetation were discovered: Vyshneva Gora near Rivne, slopes of mntn. Lys and Kvituch near Milcha, Dubnovsky region, Rivne Oblast, mntn. Smordva near Smordva, Mlyniv region, Rivne Oblast, landmark Pecheny Vol near Korablische, Mlyniv region, Rivne Oblast and landmark Graboveschina near Vladislavovka, Mlyniv region, Rivne Oblast. All six selected areas are located on the chalky mesas with fragments of vegetation concentrating mainly on the southern and south-western slopes. The analysis of the literature and personal field studies confirm the growth of many rare and endangered species of Ukrainian flora in those areas, among which are the following: Stipa capillata, Adonis vernalis, Allium sphaerocephalum, Linum flavum, Iris hungarica, Aster amellus,Inula ensifolia, Teucricum chamaedrys, Peucedanum lubimenkoanum, Festuca valesiaca, Daphne cneorum L., Ranunculus zapalowiczii Pacz., Teucrium montanum Kern., Carlina onopordifolia Bess. ex. Szaf.etc. The analysis of the fragments of the rare prairie vegetation on the examined territory was completed. Phytocenotic description of those areas was documented. Rare and endangered species of the region were inventoried, the ecologo-coenotic conditions of their vegetation examined, the reasons of reduction of population of the species discovered. Every area that has been analyzed is a part of the natural reserve, however the monitoring activities have indicated the regression of the population of certain rare species. The reason behind it is the overgrowth of more aggressive species on the slopes which leads to the disappearance of the rare prairie colony. Therefore, it is advised to review and change the laws regulating certain activities performed on the nature reserve territory.Мета досліджень – детальне вивчення екстразональних степових ділянок на території Волинської височини. Суто степові види, а також види, пов’язані з карбонатними степами, є рідкісними або малопоширеними для цього регіону. Завдання роботи – здійснення інвентаризації таких видів на території Волинської височини, вивчення еколого-ценотичних умов їх зростання, виявлення причин скорочення чисельності цих видів та розробка наукових основ їх охорони. У результаті проведених моніторингових досліджень на території Волинської височини виділено окремі ділянки степової рослинності, що зосереджені на території Рівненської області: на Вишневій горі біля Рівного, на схилах гір Лиса й Квітуча біля с. Мильча Дубнівського району Рівненської області, горі Смордва поблизу с. Смордва Млинівського р-ну Рівненської обл., в урочищі «Печений Віл» поблизу с. Кораблище Млинівського р-ну Рівненської обл. та урочищі «Грабовещина» поблизу с. Владиславівка, Млинівського р-ну Рівненської обл. Усі шість окреслених ділянок приурочені до крейдяних останцевих пагорбів, а фрагменти степової рослинності зосереджені переважно на південних або південно-західних схилах. Аналіз літературних джерел і власні польові дослідження свідчать про зростання на таких ділянках багатьох рідкісних і зникаючих видів флори України, а саме: Stipa capillata, Adonis vernalis, Allium sphaerocephalum, Linum flavum, Iris hungarica, Aster amellus, Inula ensifolia, Teucricum chamaedrys, Peucedanum lubimenkoanum, Festuca valesiaca, Daphne cneorum L., Ranunculus zapalowiczii Pacz., Teucrium montanum Kern., Carlina onopordifolia Bess. ex. Szaf. та ін. Проведено аналіз фрагментів раритетної степової рослинності на досліджуваній території. Наведено фітоценостичні описи таких ділянок. Здійснено інвентаризацію рідкісних та зникаючих степових видів регіону, вивчено еколого-ценотичні умови їх зростання, виявлено причини скорочення чисельності цих видів. Кожна з проаналізованих степових ділянок регіону є природно-заповідним об’єктом, проте моніторингові дослідження свідчать про регресивний стан популяцій окремих раритетних видів. Причина цього – заростання степових схилів більш агресивними видами та, як наслідок, такі рідкісні степові угрупування просто зникають. Тому доцільно провести перегляд і внести певні зміни до законів, що регламентують певні види діяльності на території заповідних об’єктів
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
We 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

Author Under Sail The Imagination of Jack London, 1893-1902
In Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
