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
Assessment of tooth movement efficiency during classical orthodontic and clear align therapy
Get PDFThe process of orthodontic tooth movement is initiated by applying forces to the teeth via particular appliances that orthodontists carefully choose, place, and activate based on the identified malocclusion. The response of the teeth and their supporting tissues to these forces involves a complex biological reaction, resulting in the movement of the teeth through the surrounding structures. Conventional orthodontic treatment utilizing fixed appliances facilitates tooth movement to treat different kinds of malocclusion by employing fixed components on the surfaces of teeth, including orthodontic bands, brackets, archwires, ligatures, and abutments. The popularity of aligners in orthodontic treatment has notably increased in recent years, especially among older individuals primary because of their aesthetic advantages, comfort, and the ease of maintaining oral hygiene compared to conventional fixed braces. Regarding the importance of this issue from a clinical perspective, and because this issue is underpinned by scientific literature, we have set the following aim for this study- to compare the movement of the crown and root of the tooth between the two studied groups (traditional braces therapy and aligner therapy) after a predetermined time frame from the beginning of treatment. To achieve the defined objectives, a clinical trial was conducted at the private dental office "ALJBI ORTODENT" in Tetovo. Total number of 360 teeth from 30 subjects suffering from primary crowding malocclusion were included in this study. The study population as categorized into two groups of 15 individuals each, as follows: (1)First group: 15 patients, a total of 180 teeth, from both genders,
who will be treated with a fixed appliance, DentaurumRrooth 0.22. and (2) second group: 15 patients, a total of 180
teeth, of both genders, who will be treated using an aligner, Biolon 0.75.The post-treatment digital models and the final virtual treatment plan were exported from the software as STL files and subsequently imported into Geomagic Qualify® software for comparison of the final tooth positions. Variations were calculated and analyzed for statistical significance for each tooth in the mesial-distal dimensions. For F=1.700 and p>0.05 (p=0.193) there is no significant difference between the value of the mesial-distal direction of the teeth at the beginning of the study (To), one month after treatment (T1), three months after treatment (T3), treated with a fixed appliance and an aligner. Clear aligner therapy marks a notable progression in orthodontic care, providing benefits over conventional braces, including enhanced aesthetics, greater comfort, and improved oral hygiene. Research indicates that clear aligners are effective in addressing mild to moderate malocclusions, requiring fewer visits and shorter treatment times than traditional fixed appliances. Consequently, it is essential for clinicians to weigh the attributes of these two types of orthodontic devices when determining treatment options.

Analysis of three-dimensional tooth movement with fixed appliance and aligner treatment
Get PDFMost people dream of having a perfect smile. However, some individuals avoid therapy with fixed orthodontic appliances for one reason: the brackets are visible and would interfere with some professions. Fortunately, there is a discreet way to straighten teeth – with invisible clear aligners. Thanks to numerous media and social media adverts promoting various orthodontic techniques and products for correcting malocclusions, patients can select several new modalities. One of the most potent uses of digital technology is Clear Aligner Therapy (CAT), in which stimulation is used to electronically program tooth movement. The main aim of the study was to show implementation of digital technology three-dimensional for assessment of tooth movement following different orthodontic therapy- classical orthodontic fixed appliance and aligners. Digital technologies are used in orthodontics as well; they provide computerized visual prediction of treatment outcomes. Planning, measurements, and stimulations are carried out on a precise 3D representation of the teeth, which is first obtained by digital models created from scans of plaster models or direct intraoral scans. The research was done in private dental office ("Albi Ortodent" Tetovo,N. Macedonia)and all patients with frontal toothcrowding in both jaws received treatment. Aligners and fixed orthodontic appliances were used for the patient’s treatment. Digital system applications are used in orthodontics, where they provide computerized visual therapy outcome prediction.The average age was 14.5 years old, while the range of ages was 13–16.After analyzing the data, it was noted that for F=3.94 and p0.05 (p=0.0599) there is no significant difference between the values of movement in mesial-distal direction of the teeth treated with a fixed appliance and an aligner. According toPost Hoc Tests /Bonferroni test analysis, for p>0.05 (p=0.0599) there is no significant difference between the value of the mesial distal direction movement of the teeth treated with a fixed appliance and an aligner.Clear aligners can produce outcomes that are clinically acceptable and potentially comparable to those obtained through fixed appliance therapy. They support improved oral hygiene practices, which in turn enhances oral and periodontal health. However, the current body of evidence does not affirm that aligners serve as an equally effective treatment modality when compared to the established gold standard of braces.

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
