119 The Secrets of Riparian Zones: Water, Seeds, and Biodiversity

Riparian zones—the narrow but biodiverse interfaces of land and water—play a crucial role in both the environment and human society. But what shapes these rich ecotones? In this episode, Jacqueline Hoppenreijs takes us into the fascinating world of riparian vegetation and explores with us how water’s flow—both destructive and constructive—forms plant communities and sustains biodiversity. Jacqueline also highlights the critical role of seed dispersal and the impact of human activities like flow regulation that shape these vital interfaces. What happens when natural water regimes are altered, and how can we help conserve these biodiversity hotspots for future generations? Tune in as we explore the ecology of boreal riparian zones and how landscape features, water flow, and human intervention intersect to influence these habitats.

86 – Barn i rörelse

Fysisk aktivitet är bra för barns välmående, men idag är det många barn som rör sig för lite. Det görs många insatser för att ändra på detta, och det är dessa som står i fokus i Johan Högmans forskning i pedagogiskt arbete. I sin doktorsavhandling studerar Johan det som kan kallas alternativa idrottsaktiviteter, det vill säga satsningar som specifikt försöker nå de barn som inte redan är fysiskt aktiva. Med utgångspunkt i barnens berättelser synliggör Johans forskning det som framstår som betydelsefullt ur barnens egna perspektiv. I vårt samtal berättar Johan Högman mer om sina resultat och om vad som behöver ske för att alternativa idrottsaktiviteter ska bli framgångsrika.

64 – Does criticism in digital spaces matter to journalism?

With the power of digitalization, criticisms toward journalism now often are aired in digital spaces, such as social networks and blogs. But does criticism in digital spaces matter to journalism, and how do journalists handle this? These are questions asked by David Cheruiyot in his doctoral thesis in Media and Communication Studies. Through in-depth interviews with journalists, media critics, and media accountability agents, David’s research gives us an understanding of how journalistic practice in Kenya and South Africa is affected by new forms for mainstream media criticism. Prior to the digital era, journalists could deal with criticism in controlled spaces, such as letters to editors. Today, they may need to grapple with open hashtag campaigns built up by many different stakeholders of journalism. As David explains in our interview, this has profound effects on journalists and journalistic practice.

63 – Modelling the life span of the sewage system mathematically?

When old sewage pipes break, they can undermine the soil. In the worst case, this can lead to the formation of sink holes that devour buildings, vehicles and other things.

In our podcast we talk to Arthur J. Vromans who does research that can potentially predict the degradation of sewage pipes and thus prevent the formation of sink holes. For this he has developed a mathematical model that can assess the life span of existing sewage pipes and estimate the degradation rate in the sewer system over a long time period.  His work offers a way to estimate error margins, predict degradation processes and hopefully avoid series of unfortunate events related to broken sewage pipes.

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.

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“.
