‘ICreate’: Preliminary usability testing of apps for the music technology classroom

In the world of music technology where, “music practice is challenged, mediated and redefined through performers’ and composers’ uses of ICT” (Savage, 2005, p. 168), curriculum change is necessary if the world of the classroom is to keep pace with the world outside (Cain, 2004, p. 219). For newcomers to music technology, the glittering array of increasingly sophisticated flashing, emulated, and modulated interfaces can invoke virtual interface dyslexia before giving way to options anxiety. Change is the only constant in the ever-evolving techno-scape of sound and music applications. This paper proposes that the development of an introductory tertiary music technology unit curriculum using loop-based music iPad apps may effectively engage non-traditional music (NTM) students in both music and technology. The course design was underpinned by two intentions. Firstly, the aim was to stimulate student creativity and secondly, to encourage immersion (focused attention) in sonic composition (Witmer & Singer, 1998). This paper reports on the preliminary usability testing of five loop-based music iPad applications. It is administered to a sample of one, namely the author, using the System Usability Scale (SUS) (Brooke, 1996) and is guided by the following questions: Would this testing methodology be appropriate? What factors specific to loop-based music app design might be pertinent for educators? Would this testing method indicate the potential for student immersion and creativity? While the pilot study, described here, is conducted solely by the researcher to determine the effectiveness of the method, future research intends the study to be administered to a small classroom group if determined appropriate

Percutaneous transhepatic vs. endoscopic retrograde biliary drainage for suspected malignant hilar obstruction: study protocol for a randomized controlled trial

Abstract Background The optimal approach to the drainage of malignant obstruction at the liver hilum remains uncertain. We aim to compare percutaneous transhepatic biliary drainage (PTBD) to endoscopic retrograde cholangiography (ERC) as the first intervention in patients with cholestasis due to suspected malignant hilar obstruction (MHO). Methods The INTERCPT trial is a multi-center, comparative effectiveness, randomized, superiority trial of PTBD vs. ERC for decompression of suspected MHO. One hundred and eighty-four eligible patients across medical centers in the United States, who provide informed consent, will be randomly assigned in 1:1 fashion via a web-based electronic randomization system to either ERC or PTBD as the initial drainage and, if indicated, diagnostic procedure. All subsequent clinical interventions, including crossover to the alternative procedure, will be dictated by treating physicians per usual clinical care. Enrolled subjects will be assessed for successful biliary drainage (primary outcome measure), adequate tissue diagnosis, adverse events, the need for additional procedures, hospitalizations, and oncological outcomes over a 6-month follow-up period. Subjects, treating clinicians and outcome assessors will not be blinded. Discussion The INTERCPT trial is designed to determine whether PTBD or ERC is the better initial approach when managing a patient with suspected MHO, a common clinical dilemma that has never been investigated in a randomized trial.

Community radio in Western Australia: Notions of value

Although community radio in Australia is now well established and considered an important part of the radio sector, in today’s economically driven world it is at the bottom of the media money pile. In order to argue for its continuing existence, funding and development in an ever-changing media landscape, some means of capturing its value is essential. This thesis develops a theoretical framework of value for community radio from existing literature and through the testing of the framework at three community radio stations in Perth, Western Australia. Through a combination of interviews with staff, observation/participation and audience focus groups the testing exercise provides a multimodal insight into the values and operation of community radio as reflected in real life practice. The analysis will reveal whether the framework of value can be successfully operationalised in the field, how value is perceived by the study participants, and to what extent value is contingent upon the characteristics of the individual community radio stations. The evidence collected also has the potential to inform policy-making at a community radio station
