QTLs for fire blight (Erwinia amylovora) resistance in Pyrus ussuriensis.
No full textFire blight is the most devastating bacterial disease of apples and pears. The need for highly disease-resistant cultivars is more pressing than ever. Genetic disease immunity or resistance is recognized as an important feature of integrated pest management (IPM). In this study, we used an F1 progeny of Pyrus communis ‘Doyenne du Comice’ × Pyrus ussuriensis to build parental genetic maps and to identify quantitative trait loci (QTLs) related to fire blight resistance. Linkage maps were constructed using a set of microsatellites and enriched with amplified fragment length polymorphism (AFLP) markers. For the first time QTLs for fire blight resistance in P. ussuriensis were identified by the Kruskal-Wallis test in its LGs U9, U_a, U_e, Ug, and U11. QTLs identified in LGs U_e and U_g are linked to AFLP-RGA markers that additionally confirms the presence of resistance genes in these LGs. Despite the high susceptibility of P. communis ‘Doyenne du Comice’, four QTLs for fire blight resistance in this cultivar were localized in LG K3, K4, K11, and K_a. These data confirm the existence of the interspecific transgression phenomenon, also previously observed on the basis of infection level evaluation of seedlings belonging to the studied hybrid family
Ocena stabilności posturalnej kobiet z deformacją stopy o charakterze palucha koślawego
No full textWstęp. Paluch koślawy jest postępującą deformacją stóp charakteryzującą się bocznym odchyleniem palucha z przyśrodkowym odchyleniem I kości śródstopia. Deformacja stóp oraz związane z nią objawy wiążą się ze znacznymi dolegliwościami i poważnymi skutkami zdrowotnymi w postaci ograniczeń funkcjonalnych i często występujących upadków. Cel badań. Celem pracy była ocena stabilności posturalnej kobiet w wieku 26-75 lat z deformacją stopy o charakterze palucha koślawego w porównaniu z grupą kontrolną. Materiał i metoda. Badaniami objęto grupę 88 kobiet w wieku od 26 do 75 lat, w tym 47 kobiet z koślawością palucha i 41 kobiet bez cech koślawości. Badania przeprowadzono w Centrum Podiomed przy ul. Prądnickiej 10 w Krakowie, w okresie od września 2014 do kwietnia 2015 roku. Klasyfikacji do grup dokonano na podstawie wartości wielkości kąta palucha koślawego. Dla kąta powyżej 15° sklasyfikowano kobiety do grupy badawczej, natomiast dla kąta poniżej 15° do grupy kontrolnej. Głównym narzędziem pomiarowym służącym do wyznaczenia parametrów stabilometrycznych i odbitek stóp była mata tensometryczna PLATFORMA E.P.S./R1 wraz z oprogramowaniem Biomech 2013. Pomiar na macie obejmował analizę w warunkach statyki. Pomiar stabilności trwał 5 sekund. Kąt palucha koślawego (HVA) dla każdej ze stóp wyznaczany był manualnie. Wyniki. Występowanie palucha koślawego determinuje duże zmiany w stabilności posturalnej badanych kobiet. Wnioski. Stwierdzono występowanie statystycznie istotnych różnic między wartościami parametrów stabilometrycznych i odbitek stóp kobiet z deformacją stóp i zdrowych. W grupie badawczej stwierdzono statystycznie istotne związki między wartościami kąta palucha koślawego a niektórymi parametrami stabilometrycznymi i odbitek stóp.Introduction. Hallux valgus is a progressive form of deformity of feet with lateral deviation of the hallux and medial deviation of the first metatarsal. This deformity along with its accompanying symptoms is associated with significant pain and serious consequences in terms of the patient’s physical restrictions and frequent falls. Aim of the Study. The study assessed the postural stability of women aged between 26-75, suffering from hallux valgus, as opposed to the control group. Material and methods. The study involved a group of 88 women aged 26-75, including 47 women with hallux valgus and 41 without this deformity. The study was conducted between September 2014 and April 2015, at a medical centre called Centrum Podiomed located in Krakow. The subjects of the study had been assigned t
Charakterystyka warunków statycznego i dynamicznego obciążania powierzchni podeszwowej stóp u kobiet z koślawym zniekształceniem palucha
No full textIntroduction: Hallux valgus is one of the most common foot deformations, which occurs twice as frequently in women than in men. The aim of the study was to evaluate the feet soles pressure distribution pattern of young women with hallux valgus deformity.
Material and methods: The study sample consisted of 23 young women (21-27 years). Among the participants, 14 demonstrated the presence of single- or double-sided hallux valgus (study group – a total of 22 feet with hallux valgus) and 15 women had the correct angle of the big toe for one or both feet (control group – a total of 23 feet without deformation). The research tool was the Podoscan 2D platform and the FreeMED force platform (Sensor Medica, Italy). Using the FreeStep Professional software on the plantocontourograms of the feet, the angle of hallux valgus was determined (ALFA angle). In statics the following parameters were assessed: maximal fore- and rear-foot loading, percentage loading of forefoot and the Weissflog indicator, and in dynamics (gait): the percentage loading of forefoot and medial part of the foot, the value of maximum foot pressure and the passage point of the center of pressure line.
Results: There were no differences between the study and control group regarding loading of the fore- and rear-foot or pressure distribution pattern on the lateral and medial side of the foot, however, statistically significant differences were observed in the value of the Weissflog indicator and the exit place of the center of pressure line.
Conclusions: 1. Hallux valgus deformity changes the foot rollover pattern, in which instead of the big toe as the main place to transfer forces during the final support phase, the increased load is transferred through the second foot ray. 2. hallux valgus promotes flattening of the transverse arch of the foot. 3. changes in foot pressure pattern observed in the group of women with hallux valgus are not dependent on the valgus angle.Wstęp: Koślawość palucha jest jedną z najczęstszych deformacji stopy, która z dwa razy większą częstotliwością występuje u kobiet. Celem pracy była ocena wzorca obciążenia powierzchni podeszwowej stóp młodych kobiet z deformacją koślawą palucha.
Materiał i metody: Materiał badany stanowiły 23 młode kobiety (21-27 lat). U 14 badanych wykazano występowanie koślawości palucha jedno- lub obustronne (grupa badana – łącznie 22 stopy z koślawością palucha), a u 15 kobiet wykazano prawidłowy kąt ustawienia palucha dla jednej lub obu stóp (grupa kontrolna – łącznie 23 stopy bez deformacji). Narzędzie badawcze stanowił Podoscan 2D oraz platforma sił reakcji podłoża FreeMED (Sensor Medica, Włochy). Wykorzystując oprogramowanie FreeStep Professional na plantokonturogramach stóp wyznaczono kąt koślawości palucha (kąt ALFA), w statyce oceniono parametry: maksymalne obciążenie przodo- i tyłostopia, procentowe obciążenie przodostopia oraz wskaźnik Wejsfloga, a w dynamice (chód): procentowe obciążenie przodostopia i przyśrodkowej części stopy, wartość maksymalną sił nacisku stopy na podłoże oraz miejsce wyjścia linii centrów nacisków.
Wyniki: Nie wykazano różnic pomiędzy grupą badaną i kontrolną w obciążeniu przodostopia i tyłostopia oraz w rozkładzie obciążeń na boczną i przyśrodkową stronę stopy, zaobserwowano natomiast statystycznie istotne różnice w wartości wskaźnika Wejfsloga i w miejscu wyjścia linii centrów nacisków.
Wnioski: 1. Koślawość palucha zmienia wzorzec odbicia stopy od podłoża, w którym zamiast palucha, jako głównego miejsca przeniesienia sił w trakcie końcowej fazy podporu, zwiększone obciążenie przenoszone jest przez drugi promień stopy. 2. Koślawość palucha sprzyja spłaszczeniu łuku poprzecznego stopy. 3. Obserwowane w grupie kobiet z koślawością palucha zmiany w obciążeniu stopy nie są zależne od kąta koślawości
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
No full textWe 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
Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
The Thursday Murder Club: Launching a megabrand author - a publishing case study
No full textIn 2020, the Christmas book charts in the UK made headlines: Barack Obama’s eagerly awaited autobiography, The Promised Land, was beaten to the top spot by The Thursday Murder Club by Richard Osman, a debut cosy crime novel set in a retirement village. Not only did Osman’s book beat the former US president’s expected bestseller, it also broke records, becoming the fastest-selling debut crime novel of all time. Although Osman has a certain level of fame in the UK from his TV appearances on shows such as Pointless, his celebrity status does not entirely explain the novel’s huge sales. This article tracks the acquisition, publication, and promotion journey of The Thursday Murder Club in order to understand the industry and cultural context of its success and to interrogate the role of celebrity in the creation of author brands. The findings suggest that the unexpected scale of the success of the book owed to a number of factors, including in-depth editing by the novel’s agent, editor, and author to tighten up the plot, an extensive and strategic promotional campaign, the pandemic (which drove interest in the book’s genre and themes), and the quality of the writing. We find that the book’s success was accentuated by Osman’s celebrity status rather than being entirely reliant on it. This research adds to the growing scholarship on celebrity authorship by means of an in-depth case study and provides insight into the processes behind publishing a ‘celebrity’ book and launching a megabrand author
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.
