Abnormally length of the styloid process:an anomaly underestimated of the temporal bone with surgical and clinical relevance
No full textObjective: We conducted an osteometric study in humans on styloid process of temporal bone to determine the average length and the frequency of a process excessively long that can cause unrecognized cerebrovascular syndromes or a form of neuralgia of the glossopharyngeal nerve: “Eagle syndrome.” Study Design: Measurement of styloid process was conducted on a significant part of the entire collection of skulls which showed the whole process. To highlight differences in the length of the process related to sex we have divided the skulls in two different groups by gender. Material and Methods: We measured the length of the styloid process by a digital caliper on a sample of 153 dried skulls of local museum “Leonetto Comparini.” Data was analyzed through statistical software (Salstat2, Sourceforge, Dice Holdings Inc.): average and standard deviation (SD) were calculated. A t-test was applied to the means of the two groups different for sex. Results: The average length of styloid process is 27 mm. The range of normality (average + 2st) was 42 mm. An abnormal long styloid process > 42 mm is present in 6% of items. The greatest length observed for the styloid process was 52 mm. In one case of a stylohyoid calcified ligament the styloid process was long length being 70 mm. The difference between the averages of different groups by sex was not significant. Conclusion: The presence with a certain frequency of an elongated styloid process must lead to find out this anomaly radiologically in the case of suspected “Eagle syndrom
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
A Folklore Confirmation on the Removal of Dead Code
No full textIn this folklore-confirmation short paper, we present the results of a study on the removal of dead code. We aim to gather evidence on the impact of dead-method removal on the internal structure of source code and the usage of resources such as compilation time and space to store executable code. To that end, we studied 23 open-source Java desktop applications hosted on GitHub. We cleaned up each of these applications from its dead methods to obtain two versions: one with dead methods (i.e., original version) and another one without them (i.e., cleaned version). For each of these applications, we compared its versions (original and cleaned) to determine whether, and to what extent, the removal of dead methods affects the internal structure of source code and the usage of resources. We observed that, after removing dead methods, the internal structure of source code significantly improves, while the time to compile source code significantly diminishes as well as the space to store executable code
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
