Noise-induced hearing loss in military personnel: a comparative review
Get PDFMilitary service members are often exposed to damaging occupational noise levels. The focus of this research is to investigate why noise induced hearing loss is still so prevalent in the military today, despite modern day regulations, protection, and programs. I will be working on this research under the guidance of Dr. Arnao and Professor Beers, as my senior thesis advisors. Primarily using peer reviewed journals and government statistics, as well as surveys, I will be investigating and documenting the correlation between combat and noise-induced hearing loss. I will be discussing the different sources of noise exposure in the military. I will also discuss how the different branches of the military compare in their noise exposure, as well as comparing hearing conservation and hearing protection of soldiers/sailors/airmen during the Vietnam War to those of more recent wars. I will be delving into the history of audiology within the military as well as the science of audiology itself, and attempting to explain why hearing loss is still the number one disability among veterans. In conclusion, I will summarize and discuss the commonalities and/or differences found between the published literature and the survey results.NASUNY College at New PaltzHonorsB
Using Pupillometry to Evaluate Listening Effort in Veterans with Dual Sensory Impairment
No full textThe purpose of this study is to obtain pupillometry responses from Veterans with dual sensory impairment (DSI; hearing and vision loss) and Veterans with single sensory impairment (SSI; hearing loss) while listening to a variety of acoustic stimuli. Task-invoked pupil dilation reflects components of listening effort and affective processing, and we will use pupillometry to determine whether these processes differ amongst elderly participants with DSI and SSI. We will present the data as a case series and expect to find overall greater pupil dilation responses within the DSI group. Participants must be 82 years or younger, with a diagnosis of either hearing impairment and vision impairment, or hearing impairment and no vision impairment. They must be hearing aid users. Exclusion criteria includes severe post-traumatic stress disorder (PTSD), severe psychiatric illness, recent illicit substance abuse, and use of a prosthetic eye. Each participant is required to complete the following questionnaires: Tinnitus Handicap Inventory, Inventory of Hyperacusis Symptoms, Beck’s Depression Inventory. Root mean squared error (RMSE) values will be measured to ensure a proper hearing aid fit. We will analyze changes in pupil dilation during specific time landmarks, including the listening and “rehearsal” phases. We will analyze these pupil responses to AzBio sentences presented in quiet and at a +5 dB signal-to-noise ratio (10 practice sentences + 80 trials), and affective sounds (five practice sounds + 60 trials). We are actively recruiting participants and anticipate recruiting 3-5 participants in the DSI group and 3-5 age-matched controls in the SSI group
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
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
