L’accoglienza dei minori non accompagnati in Italia alla luce degli obblighi internazionali
No full textL'indagine è volta a verificare la compatibilità del sistema italiano di accoglienza dei minori non accompagnati con le norme ricavabili dai trattati internazionali (in particolare dalla Convenzione delle Nazioni Unite sui diritti del fanciullo e dalla CEDU) e dal diritto dell'Unione europea (in particolare dall'acquis sull'asilo)
La prevenzione delle malattie del cavo orale in età evolutiva: studio osservazionale trasversale nella popolazione generale e nei pazienti portatori di ortodonzia fissa.
No full textSebbene tutti i soggetti in età pediatrica debbano essere considerati ad elevato rischio per lo sviluppo di carie e gengivite placca-correlata, un gruppo particolarmente fragile, da questo punto di vista, è rappresentato dai portatori di apparecchio ortodontico fisso; parte del progetto focalizzerà la propria attenzione su questo gruppo di pazienti, che devono essere necessariamente inseriti in un programma di prevenzione e trattamento personalizzato, in grado di accompagnare tutte le fasi del trattamento ortodontico. La carie dentale e le malattie parodontali (in particolare la gengivite marginale) sono infatti riconosciute come probabili sequele negative del trattamento ortodontico, conseguenti ad una inadeguata igiene orale durante il corso della terapia
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
State of the art on correlations between periodontal disease and systemic pathologies. A critical review of the literature of periomedicine associated with a survey in adult population.
Get PDFPeriodont disease represents the first cause of tooth loss in the adult population of industrialized countries, resulting in a serious impairment linked to the consequent loss of chewing and phonation. It also leads to a serious problem in relationships and in the aesthetics of the smile. In addition, for years now, it has been known that periodontitis can cause changes in the whole organism. Numerous clinical and experimental studies have in fact highlighted the presence of a strong association between this pathology and some systemic diseases, in particular, cardiovascular diseases, diabetes mellitus, Alzheimer's disease, respiratory diseases and complications during pregnancy. The aim of this work is to evaluate the knowledge of the correlation between periodontal disease and systemic diseases in the population, by submitting a questionnaire. Results: This study confirmed the existence of a correlation between periodontal disease and the onset of the previously mentioned systemic pathologies. In particular, there are two mechanisms mostly involved in the pathogenesis of these associations: the passage of periodontal pathogens in the systemic circulation and the systemic production of inflammatory mediators. In the first case samples of periodontal pathogens were indeed found inside the atherosclerotic plaques of patients with cardiovascular pathologies, inside the amniotic fluid and the placenta and in the brain and cerebrospinal fluid of patients affected by Alzheimer's disease. Also pulmonary translocation of oral pathogens has been shown to cause bacterial pneumonia. Instead in the second case it has been shown that the constant presence of pro-inflammatory cytokines can cause further vascular and brain damage. In addition, some of these cytokines can induce premature birth and increase insulin resistance in diabetic subjects. Furthermore, the survey has shown that, although most of the respondents knows about periodontal disease and its possibilities for prevention and treatment, knowledge of its correlation with the development of systemic diseases is still not very widespread. In fact, only a third of the sample is aware of these correlations and with regards to Alzheimer's disease, this percentage reaches 5%. Conclusions: In the future further studies will have to be conducted to determine the mechanisms involved in the correlation between periodontal and systemic diseases, especially with regard to Alzheimer and some respiratory diseases. Finally, the dental hygienist appears to be extremely important in informing patients that the maintenance of correct oral hygiene can also bring benefits at a systemic level
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
