One of such breeds is the Alatau breed of cattle, bred in 1950 by crossing local Kazakh cattle with Schwyz bulls brought to Kazakhstan by immigrants from Russia. From the moment of approbation, the breed was widely spread in southeastern Kazakhstan forhalf a century (untill 2000). However, with the restructuring of the republic’s agro-industrial complex, the breeding base of the Alatau breed underwent a number of quantitative and qualitative changes, leading to a declinein all key indicators. This situation was further exacerbated by the lack of targeted breeding programs, selection efforts, and the production and use of breeding bulls from within the population. Due to the lack of genetic material for reproduction of Alatau breed, the active importation of Schwyz bull semen from the United States began , followed by its widespread use in breeding stock. As a result, the currentbreeding base of Alatau cattle consists entirely of crossbred animals with a high proportion of Schwyz genetics . This raises concerns about the complete absorption of the breed by foreign genetics and the risk of its complete disappearance. In the article the world tendencies of preservation of of indigenous and local livestock breeds of agricultural animals, their importance in the world biological diversity and also sustainable management of breeding resources of Kazakhstan are given. Based on archival and modern literary sources, the article outlines the history of Alatau breed breeding, its current state and science-based technologies for their revival. Object and purpose of research: The object of research was Alatau cattle breed, which is on the verge of extinction due to its genetic absorption by the American bred Schwyz cattle. The aim of the research was to provide a comprehensive review of the history of Alatau breed breeding, current state, reasons for the reduction in the number of purebred cattle, proposals for the preservation of the breed and prospects for its development.В течение последних лет в Республике Казахстан локальные популяции крупного рогатого скота практически вытеснены высокопродуктивными породами, что привело к значительному сокращению поголовья местных пород. Одной из таких пород является - алатауская порода крупного рогатого скота, выведенная в 1950 году путем скрещивания местного казахского скота с быками швицкой породы, завезёнными в Казахстан переселенцами с России. С момента апробации, порода в течение полувека (до 2000 г.) широко была распространена в юго-восточной части Казахстана. Однако, с реформированием агропромышленного комплекса республики, племенная база алатауской породы претерпела ряд количественных и качественных изменений, вызвавших снижение всех показателей. Это в определенной степени, также усиливалось отсутствием целенаправленной племенной работы, отбора, получения и использованию в воспроизводстве ремонтных бычков собственной селекции. В связи с отсутствием генетического материала для воспроизводства алатауской породы, начался активный импорт спермы быков швицкой породы из США и повсеместное их использование на маточном поголовье. Таким образом, к настоящему времени вся племенная база алатауского скота представлена помесным поголовьем с высокой долей кровности по швицкой породе, что в свою очередь вызывает обеспокоенность полного поглощения породы зарубежной генетикой и риска ее исчезновения. В статье приведён обзор мировых тенденций сохранения локальных, аборигенных и местных пород сельскохозяйственных животных, их значение в мировом биологическом разнообразии, а также устойчивом управлении племенными ресурсами Казахстана. На основании архивных и современных литературных источников в статье изложена история выведения алатауской породы, ее текущее состояние и научно-обоснованные технологии их возрождения. Объект и цель исследований: Объектом исследований послужил крупный рогатый скот алатауской породы, находящийся на грани исчезновения в связи с поглощением ее швицкой породой американской селекции. Цель исследований заключалась в проведении литературного обзора истории выведения алатауской породы, современного состояния, причины сокращения численности чистопородного скота, предложения по сохранению породы и перспективы ее развития.В течение последних лет в Республике Казахстан локальные популяции крупного рогатого скота практически вытеснены высокопродуктивными породами, что привело к значительному сокращению поголовья местных пород.

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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn 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.
