Abstract
CONCLUSION: Data obtained from a cohort of 10 post-lingually deaf adult patients indicated that use of a higher stimulation rate, in the setting of the main peak interleaved sampling (MPIS) strategy coupled with the Neurelec-MXM Digisonic SP cochlear implant system, gives a significant advantage in terms of speech perception if compared with a lower rate, especially in a noisy environment.
OBJECTIVES: To evaluate speech recognition performances in post-lingually deaf adult cochlear implant recipients using two different stimulation rates (260 pps/e and 600 pps/e) in the setting of the MPIS strategy combined with the MXM-Neurelec Digisonic SP cochlear implant system.
PATIENTS AND METHODS: Ten post-lingually deaf adults who consecutively received a Neurelec-MXM Digisonic SP device at the CI Center of the University of Parma participated in the study. The study was conducted prospectively as a within-subject repeated measures (ABA protocol) between January 2007 and January 2008. Each subject was exposed to and sequentially tested with two different rates of stimulation (260 pps/e and 600 pps/e), in quiet and in a noisy environment. Statistical analysis was performed on the data obtained.
RESULTS: Subjects using the MPIS strategy with a stimulation rate of 600 pps/e performed significantly better in words and phrases recognition tests in both a noisy and a quiet environment

Abstract
OBJECTIVES/HYPOTHESIS: Patients infected with HIV have an increased risk of developing sensorineural hearing loss (SNHL), yet pathogenesis of SNHL in HIV infection is still poorly understood. In subjects affected by bilateral profound or total SNHL, cochlear implantation may be the only possibility to restore a hearing level that allows them to have an acceptable quality of life.
STUDY DESIGN: Case report.
METHODS: A retrospective chart review of a HIV type 1-seropositive profoundly deafened patient who underwent cochlear implantation.
RESULTS: To date, with a follow-up of 4 years, the patient has not experienced any complication and has regained useful open-set speech perception.
CONCLUSIONS: Cochlear impairment with preserved auditory pathways can be responsible for profound SNHL in HIV-infected patients. Cochlear implantation can restore a social hearing in these patients, dramatically improving their quality of life. The surgical procedure can be safely performed when keeping in mind that the general condition of the patient is the decisive factor for or against surgery

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

Abstract
OBJECTIVE: To compare the 1-, 3-, and 6-month postoperative speech perception scores obtained by a group of subjects who received the new perimodiolar array (Nucleus Contour) cochlear implant with those obtained by a group of subjects implanted with the straight electrodes of the previous-generation Nucleus 24 device.
MATERIAL AND METHODS: The speech performance of 10 postlingually deafened adults implanted with the Nucleus Contour device was compared with that of matched controls who received the Nucleus 24 model. Objective measures included word and sentence speech recognition scores.
RESULTS: Patients implanted with the Nucleus Contour device obtained significantly higher word and sentence recognition scores after short-term use of the implant compared to those obtained by patients implanted with the Nucleus 24 model.
CONCLUSION: Further long-term studies are required to determine whether the Nucleus Contour CI recipients continue to improve over time
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
