Bone-anchored hearing aids for people with bilateral hearing impairment: a systematic review
Get PDFBACKGROUND: Bone-anchored hearing aids (BAHAs) are indicated for people with conductive or mixed hearing loss who can benefit from amplification of sound. In resource limited health care systems, it is important that evidence regarding the benefit of BAHAs is critically appraised to aid decision-making.OBJECTIVE OF REVIEW: To assess the clinical effectiveness of BAHAs for people with bilateral hearing impairment.TYPE OF REVIEW: Systematic review.SEARCH STRATEGY: Nineteen electronic resources were searched from inception to November 2009. Additional studies were sought from reference lists, clinical experts and BAHA manufacturers.EVALUATION METHOD: Inclusion criteria were applied by two reviewers independently. Data extraction and quality assessment of full papers were undertaken by one reviewer and checked by a second. Studies were synthesised through narrative review with tabulation of results.RESULTS: Twelve studies were included. Studies suggested audiological benefits of BAHAs when compared with bone-conduction hearing aids or no aiding. A mixed pattern of results was seen when BAHAs were compared to air-conduction hearing aids. Improvements in quality of life with BAHAs were found by a hearing-specific instrument but not generic quality of life measures. Issues such as improvement of discharging ears and length of time the aid can be worn were not adequately addressed by the studies. Studies demonstrated some benefits of bilateral BAHAs. Adverse events data were limited. The quality of the studies was low.CONCLUSIONS: The available evidence is weak. As such, caution is indicated in the interpretation of presently available data. However, based on the available evidence, BAHAs appear to be a reasonable treatment option for people with bilateral conductive or mixed hearing loss. Further research into the benefits of BAHAs, including quality of life, is required to reduce the uncertainty.<br/
Poe's biopics : representations of the author in D.W. Griffith's Edgar Allen Poe and James Mcteigue's The raven
Get PDFLiterary biopics often reinforce romantic images regarding the creative process, emphasizing biographic and author-centered approaches to literature previously denounced by Roland Barthes (1977). Curiously, one of the most famous critics of such romantic conceptions, Edgar Allan Poe, has himself been a victim of this very same treatment, his literary production being taken as part and result of his controversial biography in a number of works. This article analyzes two biographical films, or biopics, about the renowned poet, D.W. Griffith’s Edgar Allen Poe (sic) (1909) and James McTeigue’s The Raven (2012). The analysis of these works indicates that both reinforce the merge of the artist’s life and oeuvre, as well as the blurring of borders between fact and fiction, author and character, high and mass culture, thus contributing to the characterization of the biopic as a fitting example of historiographic metafiction. (Hutcheon, 1988).Cinebiografias literárias frequentemente reforçam visões românticas quanto ao fazer artístico, reiterando a visão biografista e a centralidade do autor há muito denunciadas por Roland Barthes (1977). Curiosamente, um dos mais célebres críticos de tais concepções românticas, Edgar Allan Poe, viu-se vítima desse mesmo tratamento ao ter sua produção literária apropriada como parte e reflexo de sua controversa biografia em diversas obras. O presente artigo debruça-se sobre dois filmes biográficos, ou biopics, acerca do célebre poeta, Edgar Allen Poe (sic), de D.W. Griffith (1909), e O Corvo, de James McTeigue (2012). A análise das obras aponta que ambas reiteram a fusão entre vida e obrado artista, bem como o apagamento das fronteiras entre fato histórico e ficção, entre autor e personagem, alta cultura e cultura de massa, contribuindo para a caracterização do gênero biopic como um dos mais bem-acabados exemplos de metaficção historiográfica (Hutcheon, 1988)
Bone-anchored hearing aids for people who are bilaterally deaf: a systematic review and economic evaluation
No full textThe aim of this systematic review, using standard methodology,was to assess the clinical and cost-effectiveness of bone-anchored hearing aids (BAHAs) for people who are bilaterally deaf. Prospective studies comparing BAHAs versus conventional hearing aids [air conduction hearing aid (ACHA) or bone conduction hearing aid (BCHA)], unaided hearing or ear surgery; and unilateral versus bilateral BAHAs were eligible. Twelve clinical effectiveness studies were included. No eligible comparisons with ear surgery were identified. Overall quality was rated as weak for all included studies.There appeared to be some audiological benefits of BAHAs compared with BCHAs and improvements in speech understanding in noise compared with ACHAs, however ACHAs may produce better audiological results for other outcomes; the limited evidence reduces certainty. Hearing is improved with BAHAs compared with unaided hearing. Improvements in QoL with BAHAs were identified by a hearing-specific instrument but not generic QoL measures. Studies comparing unilateral with bilateral BAHAs suggested benefits of bilateral BAHAs in many, but not all, situations.A decision analytic model was developed to estimate the costs and benefits of unilateral BAHAs over a ten year time horizon. The incremental cost per user receiving BAHA, compared with BCHA, was £16,344 for children and £13,281 for adults. In an exploratory analysis the incremental cost per QALY gained was between £118,898 and £55,424 for children and between £98,790 to £46,051 for adults for BAHAs compared with BCHA, depending on the assumed QoL gain and proportion of each modelled cohort using their hearing aid for eight or more hours per day. Deterministic sensitivity analysis suggested results were highly sensitive to the assumed proportion of people using BCHA for eight or more hours per day.Exploratory cost effectiveness analysis suggests that BAHAs are unlikely to be a cost effective option where the benefi ts are similar for BAHAs and their comparators. The greater the benefit from aided hearing and the greater the difference in the proportion of people using the hearing aid for eight hours or more per day, the more likely BAHAs are to be a cost effective option. The inclusion of other dimensions of QoL may also increase the likelihood of BAHAs being a cost effective option.A national audit of BAHAs is needed to provide clarity on the many areas of uncertainty surrounding BAHAs

Author Co-Citation Analysis (ACA): a powerful tool for representing implicit knowledge of scholar knowledge workers
Get PDFIn the last decade, knowledge has emerged as one of the most important and valuable organizational assets. Gradually this importance caused to emergence of new discipline entitled ―knowledge management‖. However one of the major challenges of knowledge management is conversion implicit or tacit knowledge to explicit knowledge. Thus Making knowledge visible so that it can be better accessed, discussed, valued or generally managed is a long-standing objective in knowledge management. Accordingly in this paper author co- citation analysis (ACA) will be proposed as an efficient technique of knowledge visualization in academia (Scholar knowledge workers)
Really New Stories: The Effect of Early Concept Narratives on Consumer Understanding and Attitudes
No full textReally New Stories typically describe a use setting and a main character - the hero - who is using a really new product. In this doctoral thesis, Ellis van den Hende explains why early consumer input during the development of really new products can be remarkably frustrating to new product managers and product developers. Ellis elucidates how Really New Stories can present information about the new product concept in a way that is evocative and relevant for consumers. She tests and discusses the positive effects of Really New Stories on consumer understanding and attitudes and provides practical guidelines to put Really New Stories to work. To summarize, she explains how Really New Stories successfully contribute to the new product development process. Ellis van den Hende (1981) received her graduate and postgraduate training in product development and innovation management at Delft University of Technology, The Netherlands. Her research has been published in International scientific journals, such as the Journal of Product Innovation Management.
