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
The association between breast cancer and diabetes mellitus
No full textProblēmas būtība: Saslimstība ar cukura diabētu, kā arī ar krūts vēzi ik gadu pieaug visā pasaulē. Pēdējo 150 gadu laikā veikti daudzi pētījumi, kas atklāj izteiktu saistību starp šīm slimībām. Ir nepieciešama detalizētāka izpēte analizējot kopējos slimību attīstības mehānismus, kā arī retrospektīvi izvērtējot krūts vēža gaitu un iznākumu pacientēm ar cukura diabētu, salīdzinājumā ar pacientēm bez cukura diabēta. Darba mērķis: noskaidrot, vai saslimstība ar cukura diabētu ietekmē krūts vēža gaitu un iznākumu, kā arī salīdzināt pētījuma rezultātus ar literatūrā pieejamajiem datiem. Darba metode: Pētījums veikts retrospektīvi analizējot medicīniskās kartes no Latvijas Onkoloģijas Centra un Paula Stradiņa Klīniskās universitātes slimnīcas Onkoloģijas klīnikas, laika posmā no 1994. līdz 2014. gadam. Pētījumā iekļautas 96 pacientes. Rezultāti: Krūts vēža un cukura diabēta grupā blakusslimības bija 92.2% pacienšu, turpretī grupā bez cukura diabēta – 61.1% pacienšu. Pastāv statistiski ticama saistība, ka krūts vēža un cukura diabēta grupā biežāk bija sastopama arteriālā hipertensija (p=0.01), hroniska sirds mazspēja (p=0.01) un taukainā hepatoze (p=0.00). Glikozes līmenis abās grupās samazinājās krūts vēža terapijas laikā, salīdzinot ar glikozes līmeni pirms krūts vēža terapijas. Pacientu grupā ar krūts vēzi un cukura diabētu komplikācijas bija sastopamas 47.6% pacienšu, taču grupā bez cukura diabēta 27.8% pacienšu. Grupā ar krūts vēzi bez cukura diabēta atklājās statistiski ticama saistība ar limfostāzi (p=0.004). Otrā grupā statistiska ticamība bija plaušu fibrozes komplikācijai (p=0.000). Novēroja, ka mirstības rādītāju rezultāti abās grupās bija ļoti līdzīgi un nepastāvēja izteiktas atšķirības starp šiem rādītājiem. Grupā ar krūts vēzi un cukura diabētu vidējā dzīvildze bija 6.4 gadi, bet grupā ar krūts vēzi tā bija 4.8 gadi. Secinājumi: 1.Pacientēm ar cukura diabētu un krūts vēzi no riska faktoriem procentuāli biežāk bija aptaukošanās. 2.Pacientēm ar cukura diabētu un krūts vēzi bija vairāk blakusslimību. Citas lokalizācijas vēža prevalence bija nedaudz izteiktāka pacienšu grupā bez cukura diabēta. 3.Abās pētāmajās grupās krūts vēža terapija samazināja glikozes līmeni asinīs. 4.Cukura diabēta terapija neietekmēja krūts vēža komplikācijas. 5.Vairāk komplikāciju bija krūts vēža un cukura diabēta grupā. 6.Biežāk slimības progresiju novēroja pacientēm krūts vēža un cukura diabēta grupā, taču nepastāv statistiski ticamas saistības. Mirstības rādītāju rezultāti abās grupās bija ļoti līdzīgi un nepastāv izteiktas atšķirības.Introduction: Incidence both in diabetes and breast cancer is increasing every year around the world. Over the past 150 years, there has been a lot of research showing a strong connection between diabetes and breast cancer. There is a need for more detailed study of these two diseases, both in understanding common mechanisms and retrospectively assess breast cancer course and outcomes in patients with diabetes, compared with patients without diabetes. Aim: To find out whether the incidence of diabetes affects breast cancer progression and outcomes, and to compare the results of this study with the available literature data. Materials and methods: The study was a retrospective analysis of medical case histories of Oncology Centre of Latvia and Oncology Clinic of Pauls Stradins Clinical University Hospital during the period from 1994 to 2014. The study included 96 patients. Results: Patient group with breast cancer and diabetes comorbidities were present in 92.2% of patients, whereas the group without diabetes – 61.1% of patients. There is a statistically significant association that in breast cancer and diabetes group there is higher incidence in hypertension (p=0.01), chronic heart failure (p=0.01), fatty liver disease (p=0.00). Glucose in both groups decreases during breast cancer treatment, in comparison to a sugar level before breast cancer therapy. In a group of patients with breast cancer and diabetes, complications occurred in 47.6% of patients, but in the group without diabetes 27.8% of patients. In a group of patients with breast cancer without diabetes, there was no statistically significant association between lymphostasis (p = 0.004). The second group had statistically significant association of pulmonary fibrosis (p = 0.000). Mortality rate results in both groups are very similar and there are no significant differences. In the group with breast cancer and diabetes, the median survival rate is 6.4 years, but the group with breast cancer it is 4.8 years. Conclusion: 1.From risk factors, obesity was more common in patient group with diabetes and breast cancer. 2.Patients with breast cancer and diabetes had more co-morbidities. Other malignant disease prevalence was slightly higher in the group of patients with breast cancer. 3.In both study groups, breast cancer therapy reduced blood glucose levels. 4.Diabetes therapy had no effect on breast cancer complications. 5.Breast cancer and diabetes group had more complications than the second group. 6.Disease progression was more frequent in a group with breast cancer and diabetes, but it was not statistically significant. Mortality rate results in both groups are very similar and there are no significant differences between these indicators

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.
