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. Ala Sarah Alaqra’s licentiate thesis can be downloaded from DiVA: The Wicked Problem of Privacy : Design Challenge for Crypto-based Solutions

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. Omar Richardson’s licentiate thesis can be downloaded from DiVA: Mathematical analysis and approximation of a multiscale elliptic-parabolic system

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. Nurul Momen’s licentiate thesis can be retrieved from DiVA: Towards Measuring Apps’ Privacy-Friendliness

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. Farzaneh Karegar’s licentiate thesis can be retrieved from DiVA: Towards Improving Transparency, Intervenability, and Consent in HCI

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.

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. 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.

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“.

33 – Klassrumsbaserad bedömning

I det här avsnittet berättar Anna Öhman, doktor i pedagogiskt arbete, om hur återkoppling sker mellan lärare och elever i frisörutbildningen. Med hjälp av bland annat videoanalyser synliggör avhandlingen hur både kroppar, språk och material får betydelse för återkopplingen. Den klassrumsbaserade bedömningen är beroende av ett fungerande samspel mellan elever och lärare, berättar Anna Öhman i vårt samtal. För att läsa avhandlingen i sin helhet, följ följande länk: Återkoppling i interaktion: En studie av klassrumsbaserad bedömning i frisörutbildningen

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.

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.
