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
Ikääntyvän kuulo–epidemiologinen tutkimus
No full textAbstractAge-related hearing impairment is the most common type of hearing impairment among adults. Adult-onset hearing impairment is one of the leading causes of disease burden worldwide and it is associated with social isolation and depression. As the proportion of older people is increasing in Western countries, the socioeconomic importance of adult hearing impairment will increase notably. The aim of the present contribution was to study the epidemiological aspects of hearing and related factors among older adults. The prevalence of hearing impairment, defined either by audiometry or by a self-report, and the differences between these two were analyzed. Tinnitus and hyperacusis were also studied. Furthermore, the prevalence of ear diseases, otological risk factors, and noise exposure and their association with hearing thresholds were analyzed. In addition, audiogram configurations and certain subject-related factors and their relation to hearing were assessed. The subjects were randomly sampled from the population register and they responded to an extensive questionnaire. Otological status was examined and pure tone audiometry was conducted. Data on 850 subjects aged 54–66 years were analyzed. Hearing impairment was found to be a highly common condition with a prevalence of 26.7% when defined by better ear and 42.2% when defined by worse ear. Men had worse hearing than women. High-frequency sloping audiogram configurations were common. Self-reported hearing difficulty and measured hearing impairment seem to be associated at high frequencies. At least one ear disease or otological risk factor for hearing impairment was found among 18.4% of the subjects and noise exposure among 46%, more often by men. Interestingly, noise exposure did not seem to associate with hearing levels among subjects screened for ear disease or otological risk factors. The results of the present study suggest that hearing impairment is a highly common condition among older adults and this should be taken into account when future hearing healthcare is planned. Furthermore, it seems that most of the subjects reporting hearing difficulty had no measured hearing impairment according to the criteria applied for eligibility for hearing aid fitting in Finland. Based on the results of the present study, the criteria for hearing impairment entitling persons for hearing aid fitting should be reconsidered. TiivistelmäIkäkuulo on yleisin aikuisten kuulovian aiheuttaja, ja aikuisiän kuulovika on merkittävä terveydellinen haittatekijä. Kehittyneiden maiden ikäjakauman painottuessa vanhempiin ikäluokkiin aikuisten kuulovioista tulee merkittävä sosioekonominen rasite yhteiskunnille. Tutkimuksen tavoitteena oli selvittää aikuisten kuulovikojen epidemiologiaa ja kuulovikoihin liittyviä tekijöitä. Myös kuulovian vallitsevuus määriteltynä kuulokäyrän tai tutkittavan oman ilmoituksen perusteella selvitettiin. Samoin tutkittiin muita kuulemiseen liittyviä ongelmia, kuten tinnitusta ja ääniyliherkkyyttä. Edelleen arvioitiin erilaisten kuuloon vaikuttavien tekijöiden, kuten korvasairauksien, muiden kuulovian riskitekijöiden ja melulle altistumisen, vallitsevuutta väestössä sekä niiden assosiaatiota kuulemiseen. Näiden lisäksi tutkittiin kuulokäyrien muotoja ja niiden yhteyttä tutkittavan ilmoittamaan kuulo-ongelmaan. Tutkittavat valittiin satunnaisesti väestörekisteristä. He täyttivät laajan kyselylomakkeen, heidän korvansa tutkittiin lääkärin vastaanotolla ja lisäksi heille tehtiin kuulotutkimukset. Tutkimukseen osallistui 850 55–66-vuotiasta henkilöä. Tutkimus osoitti, että kuulovika on tässä ikäryhmässä hyvin yleinen löydös ja miehillä yleisempi kuin naisilla. Tutkittavan ilmoittama kuulovika ennusti mitattujen kuulokynnysten heikkenemistä korkeilla taajuuksilla (4–8 kHz). Samoin korkeille taajuuksille laskeva kuulokäyrän muoto oli yleisin. Erilaisia kuulovian riskitekijöitä raportoi 18.4 % tutkittavista. Tämän lisäksi 46 % kertoi merkittävästä altistumisesta melulle, miehet naisia useammin. Yllättäen melualtistumisella ei näyttänyt olevan yhteyttä kuulokynnyksiin siinä ryhmässä tutkittavia, joilla ei ollut korvaperäisiä riskitekijöitä kuulovialle. Tutkimustulokset osoittavat, että kuulovika on hyvin yleinen löydös tämän ikäisillä aikuisilla. Vanhenevat ikäluokat ovat merkittävä haaste kuulonhuollolle, ja tämä olisi otettava huomioon päätettäessä kuulonhuollon rahoituksesta. Useat niistä aikuisista, jotka kokivat kuulo-ongelmia, eivät kuulokäyrälöydöksensä mukaan täyttäneet Suomessa käytössä olevia kriteereitä kuulokojesovitukselle. Tämän tutkimuksen perusteella näyttääkin siltä, että kuntoutustarvetta arvioitaessa kuulovian kriteereitä tulisi kansallisesti tarkistaa ottamalla huomioon myös huonomman korvan kuulokynnykset sekä kuulon alenema korkeilla taajuuksilla.

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.
