68- The human side of idea screening

For businesses to stay competitive and survive, it is vital for them to take good care of ideas aiming at evolving the enterprise. However, assessing and evaluating new ideas, idea screening, can take time and resources, it often acts as a bottle neck during the innovation process. Thus far, research on idea screening, has focused more on the technical and procedural aspects, leaving the human side of the process aside. For this reason, in his research Alexandre Sukhov, Ph.D. in Business Administration, has taken the perspective of the individuals involved as evaluators of ideas. By investigating more than 1,300 idea screening cases performed by 245 people, he has come to the conclusion that there is more to the process than mere screening. In fact, evaluators are co-constructing the very ideas they are set to screen. In our interview, Alexandre explains what this means for our understanding of the innovation process, and how his results can help businesses improve their innovation processes .

65 – Improving organic solar cell technology

Solar energy is a renewable energy source much needed as the global energy demand and the speed of climate change increase. Solar energy can be converted to electric energy by means of organic photovoltaics (OPV). This is a technology that uses organic molecules, such as polymers, to absorb sunlight and generate electricity. While OPV devices have become more efficient, one problem is that their operational lifetime is still short. One reason for this, is that the polymer and fullerene materials used in OPV:s degrades when it is exposed to light and air. This problem is addressed in Vanja Blazinic’s research in physics. In our conversation, he explains how his research contributes to a better practical understanding of material degradation in OPV devices. This is much needed for this technology to contribute to a brighter future.

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.

58 – Academics’ reactions to managerialism

What is managerialism in higher education? And how do academics react to it? These are the two principal questions posed by Jo Ese, in his doctoral thesis in Working Life Science Defending the university? Academics reactions to managerialism in Norwegian higher education? While managerialism has been developed in the world of business, many government run universities also have adopted this belief system. In our interview, Jo Ese explains the emergence of the concept. Also, we learn more about the strategies academics use to cope with or – as is often the case – resist managerialism.

52 – Utbildning för hållbar utveckling

För att unga människor ska kunna verka för hållbar utveckling har det gjorts stora globala satsningar på utbildning. Som ett led i detta arbete har många länder satsat på certifieringsprogram, som är tänkta att stödja skolornas implementering av utbildning för hållbar utveckling. Hittills finns dock få studier som undersöker effekterna av sådana certifieringsprogram, och det är denna kunskapslucka som Daniel Olsson fyller med sin forskning. Genom stora enkätundersökningar till skolelever i Sverige och Taiwan har Daniel kunnat mäta elevers medvetenhet om hållbar utveckling. I vårt samtal berättar Daniel om resultaten av studierna, och vilka implikationer han ser för den svenska skolan. Daniel Olssons doktorsavhandling kan hämtas från DiVA: Student Sustainability Consciousness : Investigating Effects of Education for Sustainable Development in Sweden and Beyond

51 – Fixing WiFi

Do you have high speed internet to your home but still experience  buffering or lag when watching a movie or playing an online game? These problems may be related to your WiFi network. Good thing then that researchers are working on to fixing WiFi! In Toke Høiland Jørgensen’s research he not only produces more knowledge on WiFi performance barriers, he also develops mathematical and technical solutions to them. In our conversation Toke explains how the open source solutions developed by him and his colleagues can benefit all us speed-craving internet users.

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.

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.

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
