No full textMechanical vibration and noise exposure on board of aircrafts
No full textMeasurements and risk assessment for mechanical vibration and noise are regulated by EU Directives 2002/44/CE and 2003/10/CE. In vibration databases we found vibration values data about several vibrating tools and some kind of ground vehicle, but there is a lack of data in the field of the air transport industry. Strictly related with vibration is noise: they have the same physical and mechanical nature and, remarkable by the point of view of the evaluation of the risks on health and safety of workers exposed, one of their synergic effects seems to be an increased Hearing Temporary Threshold Shift (T.T.S.), compared to T.T.S. due to noise only. Our work is the starting point to an accurate measurements to promote a risk analysis campaign particularly aimed at the air transport business.
Following the instruction set down by ISO Standards 2631-1 and UNI 9432 (2002) we measured mechanical vibrations and noise the pilots of two helicopters (EUROCOPTER EC 135 and AGUSTA BELL AB 412) and one airplane (BOMBARDIER CANADAIR CL 415) were exposed to during regular service and training missions. Noise has been measured both directly in the headsets, with internal and external communications included, and in the cabin without protection. In the worst case (helicopter AB 412) vibration values were under ‘action’ values until 150 minutes of daily exposure. Noise was found to be under action value up to 130 minutes of daily exposure in the EC 135, while in the AB 412 and CL 415 was over the action values for less than an hour exposure. Noise generated only by communications in the headsets, especially those external, should be noted
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
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
Lower Lip Reconstruction after Skin Cancer Excision: A Tailored Algorithm for Elderly Patients
No full textBackground: Lower lip reconstruction is crucial to restore oral integrity post-cancer excision. A perfect balance between form and function should be achieved. With an aging demographic, adapting surgical methods to meet the unique needs of the elderly becomes imperative. Our study aims to introduce a specialized algorithm for lower lip reconstruction; it was tailored to geriatric patients and emphasized the use of “simpler flaps”. Additionally, “Pearls and Pitfalls” were provided for surgeons approaching lower lip reconstruction. Methods: Between January 2018 and June 2021, a retrospective study was carried out. Data collection included patient demographics, defect attributes, reconstructive approaches, flap viability assessment, wound healing, and complications. The follow-up was carried out for a period of a minimum of 6 months. Results: Among 78 patients, squamous cell carcinoma predominated with a mean defect area of 3308 cm2. Postoperative complications were recorded in two patients. All patients reported sensory restoration and overall satisfaction at the 6-month follow-up; secondary procedures were not necessary. Conclusion: Our reconstructive algorithm, focused on elderly patients, prioritizes less invasive reconstructive techniques and introduces innovative modifications to the established methods to achieve both aesthetic and functional outcomes with a low complication rate. In patients undergoing lower lip reconstruction, the subjective microstomia was found to be less relevant than the objective microstomia
