- In this article, we present our work on the sonification of notated complex spectral structures. It is part of a larger research project about the design of a new notation system for representing sound-based musical structures. Complex spectral structures are notated with special symbols in the scores, which can be digitally rendered so that the user can hear key aspects of what has been notated. This hearing of the notated data is significantly different from reading the same data, and reveals the complexity hidden in its simplified notation. The digitally played score is not the music itself but can provide essential information about the music in ways that can only be obtained in sounding form. The playback needs to be designed so that the user can make relevant sonic readings of the sonified data. The sound notation system used here is an adaptation of Thoresen and Hedman’s spectromorphological analysis notation. Symbols originally developed by Lasse Thoresen from Pierre Schaeffer’s typo-morphology have in this system been adapted to display measurable spectral features of timbrel structure for the composition and transcription of sound-based musical structures. Spectrum category symbols are placed over a spectral grand-staff that combines indications of pitch and frequency values for the combined display of music related to pitch-based and spectral values. Spectral features of a musical structure such as spectral width and density are represented as graphical symbols and sonically rendered. In perceptual experiments we have verified that users can identify spectral notation parameters based on their sonification. This confirms the main principle of sonification that is that the data/dimensions relations in one domain, in our case notated representation of spectral features, are transformed in perceived relations in the audio domain, and back.

Lessons for Crisis Communication on Social Media : A Systematic Review of What Research Tells the Practice
- 2018
-
Ingår i: International Journal of Strategic Communication. - : Lawrence Erlbaum Associates. - 1553-118X .- 1553-1198. ; 12:5, s. 526-551

Forskningsöversikt (refereegranskat)abstract
- This study analyzes explicit pieces of advice for effective social media crisis communication given by researchers in various sub-disciplines of strategic communication. The themes are identified by a systematic content analysis of peer-reviewed journal articles and conference papers (n = 104) published between 2004 and 2017. Five overall thematic "lessons" are identified and critically discussed. These are that effective social media crisis communication is about: (1) exploiting social media’s potential to create dialogue and to choose the right message, source and timing; (2) performing pre-crisis work and developing an understanding of the social media logic; (3) using social media monitoring; (4) continuing to prioritize traditional media in crisis situations; and finally (5) just using social media in strategic crisis communication. These guidelines mainly emerged from quantitative research conducted in the context of the United Stated and on Twitter. There is need for more research focusing on other platforms and other empirical material. There is also a future need for an in-depth methodological discussion of how to further bridge the gap between research and practice on a global scale, and how to develop more evidence-based recommendations for strategic crisis communication practitioners.

Forskningsöversikt (refereegranskat)abstract
- Our aim was to explore enablers and barriers in ordinary housing for older people in care. We systematically searched Scopus, Web of Science, and Google Scholar for relevant published research and gray material. The search resulted in a final sample of eight publications, four of which focused on accessibility for older people with dementia. Thematic analysis resulted in two themes: safety and accessibility. Future studies should focus on modifications to ordinary housing to achieve safe and comfortable environments for people who want to age in place and those who provide them with care.

- Social media data are transforming sustainability science. However, challenges from restrictions in data accessibility and ethical concerns regarding potential data misuse have threatened this nascent field. Here, we review the literature on the use of social media data in environmental and sustainability research. We find that they can play a novel and irreplaceable role in achieving the UN Sustainable Development Goals by allowing a nuanced understanding of human-nature interactions at scale, observing the dynamics of social-ecological change, and investigating the co-construction of nature values. We reveal threats to data access and highlight scientific responsibility to address trade-offs between research transparency and privacy protection, while promoting inclusivity. This contributes to a wider societal debate of social media data for sustainability science and for the common good.

Risk, crisis, and social media : A systematic review of seven years' research
- 2017

Forskningsöversikt (refereegranskat)abstract
- The literature on social media use in risk and crisis communication is growing fast, and it is time to take stock before looking forward. A review of 200 empirical studies in the area shows how the literature is indeed increasing and focusing on particular social media platforms, users, and phases from risk to crisis relief. However, although spanning 40 countries, a large proportion of the world’s social media users are under-represented in the research. In addition, little attention is given to the question of who is actually reached through social media, and the effects of the digital divide are rarely discussed. This article suggests that more attention is given to the questions of equal access to information and ICTs, complementary media channels, and cultural diversity.

Service action research: review and guidelines
- 2020
-
Ingår i: Journal of Services Marketing. - : Emerald Group Publishing Limited. - 0887-6045. ; 34:1, s. 87-99

Forskningsöversikt (refereegranskat)abstract
- Purpose Conducting research that is both practice- and theory-relevant is important for the service research community. Action research can be a fruitful approach for service researchers studying the transformative role of service research and wanting to make contributions to both the research community and to practical development. By exploring the current use of action research in service research, this study aims to make suggestions for enhancing the contribution to theory and practice development and to propose criteria for research quality for action research in service research. Design/methodology/approach This study builds on a systematic literature review of the use of action research approaches in service research. Findings The study makes three main contributions. First, it posits that any action research project needs to consider the four elements of problem identification, theorization, creating guiding concepts and intervention. Second, based on these elements mirrored in service action research, it outlines and analyzes three approaches to action research (i.e. theory-enhancing, concept developing and practice-enhancing). Third, it suggests a move from instrumental to a more conceptual relevance of the research and elaborates on the criteria for research quality. Originality/value This study contributes to the understanding of how action research may be applied for conducting high-quality collaborative research in services and proposes measures to enhance research quality in action research projects focusing services.

Technologies for Interoperable Internet of Medical Things Platforms to Manage Medical Emergencies in Home and Prehospital Care : Protocol for a Scoping Review
- 2022
-
Ingår i: JMIR Research Protocols. - : JMIR Publications Inc.. - 1929-0748. ; 11:9
-
Forskningsöversikt (refereegranskat)abstract
- Background: Population growth and aging have highlighted the need for more effective home and prehospital care. Interconnected medical devices and applications, which comprise an infrastructure referred to as the Internet of Medical Things (IoMT), have enabled remote patient monitoring and can be important tools to cope with these demographic changes. However, developing IoMT platforms requires profound knowledge of clinical needs and challenges related to interoperability and how these can be managed with suitable technologies.Objective: The purpose of this scoping review is to summarize the best practices and technologies to overcome interoperability concerns in IoMT platform development for medical emergencies in home and prehospital care.Methods: This scoping review will be conducted in accordance with Arksey and O’Malley’s 5-stage framework and adhere to the PRISMA-P (Preferred Reporting Items for Systematic Reviews and Meta-analyses Protocols) guidelines. Only peer-reviewed articles published in English will be considered. The databases/web search engines that will be used are IEEE Xplore, PubMed, Scopus, Google Scholar, National Center for Biotechnology Information, SAGE Journals, and ScienceDirect. The search process for relevant literature will be divided into 4 different steps. This will ensure that a suitable approach is followed in terms of search terms, limitations, and eligibility criteria. Relevant articles that meet the inclusion criteria will be screened in 2 stages: abstract and title screening and full-text screening. To reduce selection bias, the screening process will be performed by 2 reviewers.Results: The results of the preliminary search indicate that there is sufficient literature to form a good foundation for the scoping review. The search was performed in April 2022, and a total of 4579 articles were found. The main clinical focus is the prevention and management of falls, but other medical emergencies, such as heart disease and stroke, are also considered. Preliminary results show that little attention has been given to real-time IoMT platforms that can be deployed in real-world care settings. The final results are expected to be presented in a scoping review in 2023 and will be disseminated through scientific conference presentations, oral presentations, and publication in a peer-reviewed journal.Conclusions: This scoping review will provide insights and recommendations regarding how interoperable real-time IoMT platforms can be developed to handle medical emergencies in home and prehospital care. The findings of this research could be used by researchers, clinicians, and implementation teams to facilitate future development and interdisciplinary discussions.

The Re-mediation of Legacy and New Media on Twitter : A Six-Language Comparison of the European Social Media Discourse on Migration
-
Ingår i: Social Science Computer Review. - 0894-4393.
-
Forskningsöversikt (refereegranskat)abstract
- Scholarly literature has demonstrated that hybridity transforms both legacy and new media, but that this change is not even. We treat social media platforms as arenas of remediation, where users share and add their own context to information produced by both media subtypes and compare social media conversations about migration in six European languages that include links to either traditional or new media during 2015–2019. We use a mix of computational and statistical methods to analyze 3.5 million (re)tweets and 500,000 links shared within them. We identify the main differences in agenda setting power, function, and tone present within tweets that include links to legacy or new media. Our results show that discourses are similar across languages but clearly different when remediating legacy and new media. Trust in legacy media is correlated with higher proportion of shared links from legacy media and reversely related to the proportion of shared links from new media sources. Considering the volume and timing of the remediated content, we conclude that legacy media retains its agenda setting power. New media linked content tends to cover migration in association to subjects such as Islam or terrorism and to express strong critical opinions against migrants/refugees. The language used is more toxic than in legacy media linked content. The tweets remediating legacy media articles covered topics like domestic or European politics, causes of refugee arrivals and procedures to give them protection. Thus, legacy and new media remediated content differs in both tone and function: toxicity is low and factuality high for content linking to legacy media, with the reverse being true for new media remediations.

Twenty years of online teacher communities: A systematic review of formally-organized and informally-developed professional learning groups
- 2018
-
Ingår i: Teaching and Teacher Education : An International Journal of Research and Studies. - : Elsevier BV. - 0742-051X. ; 75, s. 302-315

Forskningsöversikt (refereegranskat)abstract
- This paper presents a systematic review of 52 empirical studies of formally-organized and informally developed online teacher communities from the early 2000s to the present time. Focusing on the social as well as technological aspects of online participation, the review explores how teacher communities are shaped by broader contexts of teaching. The review shows that while formally-organized and informally-developed communities address different needs amongst teachers and support different outcomes, they also share several common characteristics. Indeed, regardless of type, online communities can be a valuable means of developing supportive and collegial professional practices. That said, more evidence is required on the specific collaborative merits of teachers' online interactions.

Forskningsöversikt (refereegranskat)abstract
- Amongst health-related scientific disciplines, microbiology appears to play a vital role in creating a sustainable future with respect to health, the environment and a biobased economy. Microbiology research covers a wide range of different disciplines and addresses many important global issues. This study aimed to identify topics being addressed within the last 5 years (2012-16) in the field of microbiology worldwide and to compare them in terms of three different indicators: gross domestic product, Human Development Index and Infectious Disease Vulnerability Index. The dataset of this study comprised 167 874 articles and reviews from 2012 to 2016, which were extracted from the Web of Science Medline. To identify and visualise the topics addressed during the studied period, VOSviewer was used. The construction and visualisation of the term map was done based on 5918 MESH subject headings. The methodology and procedures employed included Kruskal-Wallis test and two-sample proportion test. Overall, our study showed that the field of microbiology has focused on six different topics during 2012-16. The papers written with the collaboration of countries with low socioeconomic status and high vulnerability to infectious diseases mainly addressed topics related to the primary needs of people such as food safety, the prevention and control of infectious diseases, food and energy poverty. In contrast, papers written with the collaboration of countries with high socioeconomic development status and less vulnerability to infectious diseases mainly focused on big data, alternative methods to animal experiments.
