Impacto estético do diastema inter-incisivo: estudo observacional
No full textO conceito de estética tornou-se cada vez mais relevante na sociedade. Os padrões de beleza ficaram mais rígidos e difíceis de alcançar, tornando-se cada vez mais complicado definir o que é considerado esteticamente agradável de forma objetiva. A medicina dentária não é uma exceção, e na última década as exigências estéticas fizeram com que muitos pacientes procurassem o dentista com maior frequência. Pretendeu-se avaliar se existe diferença na perceção de atratividade do sorriso em presença do diastema interincisivo quando esta é avaliada por leigos e por médicos dentistas, quer em Portugal, quer em Itália. Pretende-se verificar se esta perceção difere entre género na avaliação de sorriso feminino e masculino, país (Portugal versus Itália) e faixa etária do participante (menor de 40 anos ou maior/igual a 40 anos) e a área de atuação principal dos médicos dentistas.
Estudo observacional transversal realizado após autorização da Comissão de Ética da UFP. Amostra de conveniência de médicos dentistas e leigos de Portugal e de Itália. Questionário online utilizando imagens do sorriso alteradas digitalmente (12 imagens com alterações (0 mm-4 mm) na distância entre os incisivos centrais superiores no sentido mésio-distal, para a criação de diastemas interincisivos), pedindo para classificar a autoperceção de atratividade de imagens utilizando uma escala virtual analógica (de 0 - “nada atraente” a 10 - “muito atraente”). Análise estatística descritiva e inferencial realizada recorrendo ao IBM©SPSS®Statistics vs.29.0 (α=0,05). Os resultados mostraram uma diferença significativa na perceção de atratividade entre leigos e médicos dentistas, sendo que os primeiros autopercionam de forma menos atrativa o aumento do tamanho do diastema. Para os dois grupos, verifica-se igualmente que o aumento do diastema interincisivo se relaciona com uma menor atratividade. Os médicos dentistas não ligados à estética foram mais críticos, classificando pior a atratividade, em relação aos ligados à estética. O sexo, idade e o país de origem afetaram a perceção de atratividade. Os leigos são mais rigorosos (atratividade inferior) quanto à presença do diastema no sorriso do que os médicos dentistas. A perceção de atratividade foi afetada pela faixa etária, sexo, país dos participantes e área de atuação do dentista, mas nem sempre da mesma forma para os participantes dos dois países.The concept of aesthetics has become increasingly relevant in society. Beauty standards have become more rigid and difficult to achieve, making it increasingly complicated to define what is considered aesthetically pleasing in an objective manner. Dentistry is no exception, and in the last decade, aesthetic demands have led many patients to visit the dentist more frequently. The aim was to evaluate whether there is a difference in the perception of smile attractiveness in the presence of an interincisal diastema when assessed by laypeople and dentists in both Portugal and Italy. The goal is to verify whether this perception differs between gender in the evaluation of female and male smiles, country (Portugal versus Italy), age group of the participant (under 40 years or 40 years and older), and the main field of practice of the dentists.
This cross-sectional observational study was conducted after approval by the Ethics Committee of UFP. A convenience sample of dentists and laypeople from Portugal and Italy was used. An online questionnaire using digitally altered smile images (12 images with alterations (0 mm-4 mm) in the distance between the upper central incisors in the mesio-distal direction to create interincisal diastemas) was administered, asking participants to rate the self-perceived attractiveness of the images using a virtual analog scale (from 0 - "not at all attractive" to 10 - "very attractive"). Descriptive and inferential statistical analyses were performed using IBM©SPSS®Statistics vs.29.0 (α=0.05). The results showed a significant difference in the perception of attractiveness between laypeople and dentists, with the former perceiving the increase in diastema size as less attractive. For both groups, it was also found that the increase in interincisal diastema size is associated with lower attractiveness. Dentists not related to aesthetics were more critical, rating attractiveness lower compared to those related to aesthetics. Gender, age, and country of origin affected the perception of attractiveness. Laypeople are more stringent (lower attractiveness) regarding the presence of a diastema in the smile than dentists. The perception of attractiveness was affected by age group, gender, country of participants, and the field of practice of the dentist, but not always in the same way for participants from both countries
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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.
