Musical Interaction

The widespread adoption of mobile devices, such as smartphones and tablets, has made touchscreens a common interface for musical performance. Although new mobile music instruments have been investigated from design and user experience perspectives, there has been little examination of the performers' musical output. In this work, we introduce a constrained touchscreen performance app, MicroJam, designed to enable collaboration between performers, and engage in a data-driven analysis of more than 1,600 performances using the app. MicroJam constrains performances to five seconds, and emphasizes frequent and casual music-making through a social media–inspired interface. Performers collaborate by replying to performances, adding new musical layers that are played back at the same time. Our analysis shows that users tend to focus on the center and diagonals of the touchscreen area, and that they tend to swirl or swipe rather than tap. We also observe that, whereas long swipes dominate the visual appearance of performances, the majority of interactions are short with limited expressive possibilities. Our findings enhance our understanding of how users perform in touchscreen apps and could be applied in future app designs for social musical interaction.

The musical project Crossing Roper Bar (CRB) is based on a collaboration between Wägilak songmen from Australia’s Northern Territory and the Australian Art Orchestra (AAO). Individuals drawn into this collaboration bring their distinct voices and histories to performance, while opening themselves to those of others. A new, malleable approach to orchestral performance in Australia is the result of this collaboration, which places improvisation at the centre of conversational musical interaction. This chapter introduces orthodox narrative elements of Wägilak manikay (song) that are creatively renewed and sustained in CRB. It highlights how the collaboration demonstrates the compelling play of musical performance that can generate nuanced, respectful and ongoing interactions between individuals, and between individuals and traditions. Amidst the vibrant, cultural diversity of contemporary Australian society, CRB suggests new possibilities for productive and relevant orchestral music-making.

BACKGROUND Healthcare has increased its use of information technology over the last few years. A trend followed higher usage of Electronic Health Record in low-and-middle-income countries where doctors use non-medical applications and websites for healthcare-related tasks. Information security awareness and practices are essential to reduce the risk of breaches. OBJECTIVE To assess the internal reliability of the Spanish translation of three areas of the Human Aspects of Information Security Questionnaire (HAIS-Q), and to assess the knowledge, attitudes, and practices of medical doctors around information security. METHODS This is a cross-sectional descriptive study designed as a questionnaire-based. We used focus areas (Password management, social media use, and mobile devices use) from the Human Aspects of Information Security Questionnaire (HAIS-Q). Medical doctors in Ecuador answered an online survey between December 2017 and January 2018. RESULTS A total of 434 health professionals (response rate: 0.65) completed all the questions in our study. Scores were 37.4 (SD 5.9) for Password Management, 35.4 (SD 5.0) for Social Media Use and 35.9 (SD 5.7) for Mobile Devices. Cronbach’s alpha coefficient (α) was 0.78 (95% CI: 0.75, 0.81) for password management, 0.73 (95%CI: 0.69, 0.77) for mobile devices and 0.77 (95% CI: 0.73, 0.78) for Social Media Use. CONCLUSIONS Our study shows that three components of the Spanish translation of the HAIS-Q questionnaire were internally reliable when applied in medical doctors. Medical doctors with eagerness to receive infosec training scored higher in social media use and mobile device use categories.

The Voice

This chapter asks an important, yet seemingly illusive, question: In what ways does the internet provide (or not) activist—or, for present purposes “artivist”—opportunities and engagements for musicing, music sharing, and music teaching and learning? According to Asante (2008), an “artivist (artist + activist) uses her artistic talents to fight and struggle against injustice and oppression—by any medium necessary. The artivist merges commitment to freedom and justice with the pen, the lens, the brush, the voice, the body, and the imagination. The artivist knows that to make an observation is to have an obligation” (p. 6). Given this view, can (and should) social media be a means to achieve artivism through online musicing and music sharing, and, therefore, music teaching and learning? Taking a feminist perspective, this chapter interrogates the nature of cyber musical artivism as a potential means to a necessary end: positive transformation. In what ways can social media be a conduit (or hindrance) for cyber musical artivism? What might musicing and music sharing gain (or lose) from engaging with online artivist practices? In addition to a philosophical investigation, this chapter will examine select case studies of online artivist music making and music sharing communities with the above concerns in mind, specifically as they relate to music education.

Mobile devices and social media have been used to create empowering healthcare services. However, privacy and security concerns remain. Furthermore, the integration of interoperability biomedical standards is a strategic feature. Thus, the objective of this paper is to build enhanced healthcare services by merging all these components. Methodologically, the current mobile health telemonitoring architectures and their limitations are described, leading to the identification of new potentialities for a novel architecture. As a result, a standardized, secure/private, social-media-based mobile health architecture has been proposed and discussed. Additionally, a technical proof-of-concept (two Android applications) has been developed by selecting a social media (Twitter), a security envelope (open Pretty Good Privacy (openPGP)), a standard (Health Level 7 (HL7)) and an information-embedding algorithm (modifying the transparency channel, with two versions). The tests performed included a small-scale and a boundary scenario. For the former, two sizes of images were tested; for the latter, the two versions of the embedding algorithm were tested. The results show that the system is fast enough (less than 1 s) for most mHealth telemonitoring services. The architecture provides users with friendly (images shared via social media), straightforward (fast and inexpensive), secure/private and interoperable mHealth services.

AbstractSocial media enable companies to assess consumers’ opinions, complaints and needs. The systematic and data-driven analysis of social media to generate business value is summarized under the term Social Media Analytics which includes statistical, network-based and language-based approaches. We focus on textual data and investigate which conversation topics arise during the time of a new product introduction on Twitter and how the overall sentiment is during and after the event. The analysis via Natural Language Processing tools is conducted in two languages and four different countries, such that cultural differences in the tonality and customer needs can be identified for the product. Different methods of sentiment analysis and topic modeling are compared to identify the usability in social media and in the respective languages English and German. Furthermore, we illustrate the importance of preprocessing steps when applying these methods and identify relevant product insights.

AbstractUser experience (UX) focused business needs to survive and plan its new product development (NPD) activities in a highly turbulent environment. The latter is a function of volatile UX and technology trends, competition, unpredictable events, and user needs uncertainty. To address this problem, the concept of design roadmapping has been proposed in the literature. It was argued that tools built on the idea of design roadmapping have to be very flexible and data-driven (i.e., be able to receive feedback from users in an iterative manner). At the same time, a model-based approach to roadmapping has emerged, promising to achieve such flexibility. In this work, we propose to incorporate design roadmapping to model-based roadmapping and integrate it with various user testing approaches into a single tool to support a flexible data-driven NPD planning process.

Risk perception and risk averting behaviors of public agencies in the emergence and spread of COVID-19 can be retrieved through online social media (Twitter), and such interactions can be echoed in other information outlets. This study collected time-sensitive online social media data and analyzed patterns of health risk communication of public health and emergency agencies in the emergence and spread of novel coronavirus using data-driven methods. The major focus is toward understanding how policy-making agencies communicate risk and response information through social media during a pandemic and influence community response—ie, timing of lockdown, timing of reopening, etc.—and disease outbreak indicators—ie, number of confirmed cases and number of deaths. Twitter data of six major public organizations (1,000-4,500 tweets per organization) are collected from February 21, 2020 to June 6, 2020. Several machine learning algorithms, including dynamic topic model and sentiment analysis, are applied over time to identify the topic dynamics over the specific timeline of the pandemic. Organizations emphasized on various topics—eg, importance of wearing face mask, home quarantine, understanding the symptoms, social distancing and contact tracing, emerging community transmission, lack of personal protective equipment, COVID-19 testing and medical supplies, effect of tobacco, pandemic stress management, increasing hospitalization rate, upcoming hurricane season, use of convalescent plasma for COVID-19 treatment, maintaining hygiene, and the role of healthcare podcast in different timeline. The findings can benefit emergency management, policymakers, and public health agencies to identify targeted information dissemination policies for public with diverse needs based on how local, federal, and international agencies reacted to COVID-19.

"Muggle Division" is engaged in convection production services,founded 5 years ago, so far using Instagram promotion media.However, when social media cannot provide clear and completeinformation, problems arise such as when consumers are about toorder and have to wait for customer service to respond for quite along time. Therefore we need media to answer these obstacles,namely the website, to provide more complete, clear information andorder input services without having to wait for customer serviceresponses. This study aims to design a "Muggle Division" websiteequipped with a self-service order feature. The user experiencedesign method used is the five planes user experience elementsmethod followed by writing HTML, CSS, and Javascript tags. Theresult of the design is a "Muggle Division" website with UI and UXrules. The use of UI methods includes color, layout, typography,whitespace, icons, and animation. The use of the UX method is in thestep by the step payment system and page login which provides theoption of page register for visitors who are not yet a member of the"Muggle Division".
