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
Bibliometric analysis and trends related to dental tourism: Qualitative, social, economic and ethical implications
No full textThis article delves into the multifaceted realm of dental tourism, scrutinizing patient incentives, economic ramifications, and ethical aspects. An in-depth 2023 analysis discerns research gaps, underscoring the necessity for a more exhaustive investigation to enrich the understanding of the global oral healthcare landscape. Utilizing bibliometric analysis method, the study examines the worldwide trajectory of scientific publications on dental tourism. Employing Scopus, it dissects document types, annual production, authorship, and international collaborations. The results spotlight microvariables derived from Saxena, Deheriya, Datla's macrovariables, unveiling influencers on dental tourism, ranging from social and economic to cultural factors. The study advocates for defined bilateral agreements to ensure quality care and stresses ethical considerations, emphasizing shared standards and legal implications. Economic ramifications, both positive and negative, are discussed, with an expanding global focus on dental tourism evident. In conclusion, the study accentuates micro variables, signaling avenues for future research
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
Digital workflow for the intraoral removable prosthesis of head and neck cancer patients
No full textOBJECTIVES: Obturator prostheses and removable prostheses still represent a valid option in head and neck cancer patients. The aim of the present article is to briefly review the current literature about the use of a digital workflow in the intraoral prosthetic rehabilitation of head and neck cancer patients.
MATERIALS AND METHODS: The review included articles in English published from January 2010 to December 2021. Articles regarding patients who had undergone head and neck cancer treatment and intraoral prosthetic rehabilitation by a CAD/CAM techniques in at least 1 of the prosthetic treatment stages (scanning, design, and/or fabrication) were included.
RESULTS: Thirteen articles with 66 described patients met the inclusion criteria and were included. Three types of removable prosthetic treatments were reported: 47 maxillary obturators, 18 provisional maxillary obturators, and 1 maxillary complete denture. As for 3-dimensional image capture, the most common method was intraoral scanner, followed by conventional CT scan.
As for prosthetic procedures, all treatments incorporated at least a digital workflow in one of the stages, either in design or fabrication. Concerning the CAM phase, definitive cast printing was performed in 64 patients. Only 1 patient was rehabilitated by using a completely digital workflow.
CONCLUSIONS: A completely digital workflow was rarely used in the intraoral prosthetic rehabilitation of patients with head and neck cancer. Compared to a conventional impression, intraoral digital scanning can save time and steps for dentists and technicians, thus avoiding in the dental office tray selection, material dispensing, material setting, material disinfection, and impression packaging and shipping. On the other hand, at the lab plaster, pouring, die cutting, trimming, articulation, and extraoral scanning are no longer necessary.
CLINICAL SIGNIFICANCE: The reduced laboratory working time, the avoidance of the risk of aspiration of impression materials, and the possibility of performing an adequate digital impression in spite of the trismus are important advantages associated with the digital workflow
Adenomatoid hyperplasia of the upper lip
No full textOBJECTIVESThe aim of the present article was to report a rare case of bilateral adenomatoid hyperplasia of minor salivary glands of the upper lip.MATERIALS AND METHODSAdenomatoid hyperplasia of minor salivary glands is a rare condition characterized by a benign, nonneoplastic enlargement of minor mucous salivary glands. Clinically, the lesion may be misdiagnosed as a salivary gland neoplasm or fibroma, but histological examination shows that there are usually more aggregates of normal-appearing salivary glands than are anticipated expected at that for the anatomical site. Pathogenesis is not clear, although a reactive hyperplasia to chronic trauma, such as in presence of ill-fitting complete dentures, has been suggested. Adenomatoid hyperplasia is considered an idiopathic, focal hypertrophic lesion of the minor salivary glands. Some authors consider it a developmental variation (hamartoma). Most cases of adenomatoid hyperplasia were reported to occur in the palate.RESULTS AND DISCUSSIONA 24-year-old man presented with a history of a bilateral swelling of the lips for 2 years. The lesion was painless and had progressively increased in size. There was no previous trauma or contributory medical history. On physical examination there was a bilateral ill-defined mass affecting the upper lip.CONCLUSIONSAdenomatoid hyperplasia is a rare entity in correspondence of the lip and it should be considered in the differential diagnosis of mucocele and other non-neoplastic and neoplastic lesions of minor salivary glands.CLINICAL SIGNIFICANCEHistopathological findings are fundamental to obtain a definitive diagnosis
