Forskningspodden - Karlstad University
In the Research Podcast "Forskningspodden" you will meet researchers from Karlstad University who recently presented their dissertation. One episode is released every other Wednesday. Most episodes are in Swedish but on this page you can listen to the episodes that are recorded in English.
Episode 49: Gamification in digital journalism
Whether you are aware of it or not, you have probably been subjected to gamification.
Gamification refers to the practice of businesses using game-elements in non-game contexts. Raul Ferrer Conill has investigated the role of gamification in digital journalism. Today, many digital newspapers use bonuses, badges or other rewards to make users consume more articles, and to make journalists more productive. In our conversation, Raul describes why newspapers use this approach, and how it affects the commercial and professional aspects of journalism.

Episode 48: Human aspects of data privacy
Securing data privacy on the internet is a wicked problem. It is wicked in that technological, legal, and human aspects of privacy are entangled. In her licentiate thesis Ala Sarah Alaqra has focused on the human aspects of data privacy. By letting users test a privacy enhancing scheme – redactable signatures – designed by Ala and her colleagues, her research investigates user perceptions and opinions of data privacy in eHealth. In our conversation Ala let us know more of redactable signatures, and how it can help increase data privacy in eHealth and possibly in other sectors as well.

Episode 44: Mathematical analysis of multiscale systems
If you pour a liter of water in an already half filled two liter bottle, you'll usually fill it up completely. But what if the bottle wasn't filled with liquids, but with sand and air? The mathematics you need to calculate such processes is complex and requires a so-called multiscale approach: calculating the interactions between objects with vastly different sizes. In his research, Ph.D. candidate Omar Richardson is developing a mathematical framework to analyze these and other multiscale systems. In our conversation, Omar explains how and why we do mathematical research, and describes some practical implications of his work.

Episode 43: Privacy friendly mobile apps
Mobile phone applications can be great for a range of different everyday purposes. However, most users are unaware of what the apps are doing while they are unattended. In his research, Ph.D. candidate Nurul Momen has investigated how apps behave, and how they use the personal data users authorise them to access. In our conversation, Nurul describes the dangers of personal data craving apps, and he explains how his research can help increasing transparency and protect user privacy.

Episode 41: Improving transparency in personal data processing
The European Union’s General Data Protection Regulation has been implemented to protect citizens’ data privacy by, for example, increasing control over their personal data. However, computerized systems and web services are not always effectively designed to give users the control they are legally entitled to in a usable way. In her thesis, Farzaneh Karegar, Ph. D. student in computer science, develops new solutions that enhance transparency and make it easier for users to give better-informed consent to service providers handling personal data. In our conversation Farzaneh lets us know more about the solutions, and why it is important to continue to work to improve the gap between legally-compliant and usable services.

Episode 40: Twitter and language transformation
Speech and writing are traditionally regarded as contrasting pairs with specific forms, structures, and normative values attached to them. In the time of social media, these differences are increasingly challenged. We tweet more like we talk or at least, that is how it feels. To find out whether our intuition is right we meet Peter Wikström who has studied Twitter language in his PhD thesis “I tweet like I talk: Aspects of speech and writing on Twitter”. He has investigated features such as hashtags and emojis to see what it might mean to tweet in a “talk-like” manner. Listen to learn more about shifting norms, questions of identity and authenticity, and a communication hybrid that evolved together with the advent of social media.

Episode 38: Evolution of markets from a service ecosystems perspective
How do markets evolve? And how can this evolutionary process be understood from a service ecosystems perspective? These are the main questions guiding Kaisa Koskela Huotari’s doctoral research in Business Administration. We talk to her about her thesis "The evolution of markets - A service ecosystems perspective". In our conversation Kaisa explains that markets are made up of rules and norms guiding people when exchanging innovative knowledge and skills. Markets can be disrupted, as new ideas can work as ‘game-changers’. Likewise new ideas – innovations – can after a while themselves become mainstream and turned into well-established norms. Based on her research Kaisa presents a four-phase model on market evolution, helping us understand this process of market continuity and change.

Episode 37: What are phthalates and why can they be troublesome for us?
Hard to pronounce, invisible to the human eye and regarded as a miracle compound for centuries: phthalates. They are in a huge variety of things such as toys, cars and make up and it is likely that you bump into them on a daily basis. In this podcast, we talk to Ph.D. Huan Shu about the downsides of phthalates. In her research, she has focused on phthalates in PVC flooring and their effects on human and especially children’s health. Listen to this podcast to learn more about what phthalates are, how they might trouble yours and your children’s respiratory system, and what could be done to prevent it.
You can also read more about Huan Shu’s research in her thesis “Phthalates, on the issue of sources for human uptake, time trends and health effects“.

Episode 32: Personal data privacy
In our digitalised world more and more of our personal information is registered in network computers and servers. Stakeholders handling personal information thus need to make sure their systems are secure and maintain the integrity of individuals. Automated privacy audits is one approach to ensure that stakeholders do in fact maintain the privacy of personal data. But as Jenni Reuben shows in her research, these audits can themselves subject to privacy risks. In our conversation Jenni, Ph.D. student in computer science, tells more about these risks and of the model she proposes to prevent illegitimate access to personal data.

Episode 31: Environmentalism in fiction writing
The topic of this episode is environmental apocalypses in fiction writing. We discuss this with Marinette Grimbeek, who in her doctoral thesis investigates the environmentalism of Margaret Atwood’s MaddAddam Trilogy. In fact, her research leads her out of the novels, as she finds that the MaddAddam Trilogy forms part of Atwood’s real-world environmental activism. In our conversation, Marinette describes how Atwood plays with the boundaries between fact and fiction, commercialism and activism, to promote an ecological understanding of the world.

Episode 26: The crossroads of mediatization, activism and surveillance
We rely more and more on networked media technologies and online communication channels but are we aware that the digital traces we leave behind turn into data pieces about us – that others can use?
Ilkin Mehrabov has focused on this this type of surveillance in his thesis “All Watched Over by Machines of Loving Grace”: Activist Practices in an Era of Mediatized Surveillance. In this podcast he tells us about his interest to learn more about the intersection of the processes of increased global surveillance with the practices of transnational activism – and the role of the mediatization metaprocess within both.
Follow us on our journey in which Ilkin explains how he tried to entangle the complex relationships built by public state agencies with a number of local and global private information, entertainment and telecommunications companies in different countries.
We will also learn more about how various social movements and individual activists in Azerbaijan and Turkey are affected by this merger of public political and private economic surveillance practices.

Episode 20: Making high-quality pulp from trees
In this podcast, we are digging deeper into the world of pulp and paper. Pulp is generally produced from wood and has a significant impact on our everyday life: we are dependent on the wide range of products that are made from it such as paper, textiles and personal care products. Raghu Deshpande tells us about his PhD thesis “The initial phase of sodium sulfite pulping of softwood: A comparison of different pulping options“, in which he tried to find the perfect recipe to produce high-quality pulp from softwood. His focus has been on sulfite pulping, which is more competitive than Kraft pulping when producing dissolving grade pulp with biorefinery applications.

Episode 19: How to make mobile health systems secure and privacy-preserving
Information security and privacy are vital to achieve high quality healthcare services. In this podcast we dig deeper into this issue together with Leonardo Horn Iwaya who has studied how to make Mobile Health (mHealth) systems secure and privacy-preserving. He tells us about the ever-increasing tendency of using mobile devices (e.g., mobile phones, sensors, smartwatches) to support medical and public health and the problems that come along with it due to failures in addressing security and privacy issues. After listening to this podcast you will also know more about the design of security and privacy enhancing technologies for mHealth, specially in Mobile Data Collection Systems, in which traditional paper forms are replaced by a mobile application for collecting and reporting health-related data used for public programs such as health surveys and surveillance.

Episode 16: Debloating Internet Access Networks
Ever got delayed on your way to surf the web? Then this podcast might be something for you. Toke Høiland-Jørgensen talks about his thesis “On the Bleeding Edge: Debloating Internet Access Networks” in which he studied why and how internet access delays occur. This is increasingly important in times when more and more devices are connected to the internet and applications become more interactive. We need our network to respond reliably and without unnecessary delay. Tokes work focuses on one of those delays. They are called bufferbloats and are a result of excess queueing delay in network routers that occur along the path. Learn more about what it is, why it is a problem and what can be done to make it better.

Episode 6: Climate change and transport
Extreme weather events that threat the transport sector’s functionality and safety and solutions to manage the risks are focus in our podcast with Monika Rydstedt-Nyman. Monica recently defended her licentiate thesis Managing knowledge sharing of extreme weather induced impacts on land transport infrastructure: Case study of the Swedish Transport Administration.
