La promozione della salute orale in età evolutiva: competenze e attitudini dei pediatri
OBJECTIVES. The purpose of this study is to determine how pediatricians consider their expertise in terms of oral health and if they intend or feel in a position to improve their knowledge and competences in this area.MATERIALS AND METHODS. 126 pediatricians were invited by e-mail to fill in an anonymous questionnaire developed by the American Academy of Pediatrics. For statistical analysis Chi-square test was used.RESULTS. The response rate was 56.3%; 75% of responders received an oral health training; of these, 72% had 3 hours training or less and 91% did not complete a clinical internship with a dentist.CONCLUSIONS. Pediatricians are aware of their role in the promotion of oral health, but most of them consider the training received as insufficient
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Oral Health Status in Alzheimer's Disease Patients: A Descriptive Study in an Italian Population.
AIM:
To evaluate the oral health status in Alzheimer's disease (AD) patients.
MATERIALS AND METHODS:
A descriptive study was performed on 120 AD patients (60 institutionalized in a public institute and 60 attended a daytime center), from September 2013 to January 2014. About 103 subjects formed the control group. The following medical and dental data were collected: dementia severity, pharmacological therapy, physical status (American Society of Anesthesiologists [ASA]), decayed (D), filled (F), and remaining natural teeth (T), DF/T ratio, community periodontal index (CPI), and gingival index (GI). A t-test for independent samples and the Spearman's correlation test were used to evaluate all variables. The significance level was set at 0.05.
RESULTS:
Statistically more AD patients (91.7%) were under pharmacological therapy and their physical status was more severe (ASA 2, ASA 3) compared with control subjects (p < 0.001). Moreover, they presented numbers of D, CPI, and GI significantly higher (p ≤ 0.005). In the institutionalized subgroup, statistically more moderate and severe AD cases were detected and more patients were edentulous (p < 0.001). Noninstitutionalized patients presented DF/T ratio, CPI, and GI significantly lower (p ≤ 0.024). A significant weak negative correlation (r = -0.121 to -0.372) between epidemiologic indices and AD severity was observed.
CONCLUSION:
Alzheimer's disease patients show a low oral health status that decreases progressively as the disease severity aggravates. Therefore, further studies are necessary to investigate oral health care interventions for AD patients.
CLINICAL SIGNIFICANCE:
It would be beneficial to introduce trained professional figures in specialized elderly institutions for regular follow-up visits and professional oral hygiene procedures. This task has to be coordinated with the treating physician, family members, and/or caregivers. Knowing that the severity of AD has a negative effect on the oral health status and the type of institutionalization exacerbates it
Variations on the Author
“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
We 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
We 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
We 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
