Book review: The crowdsourced panopticon: conformity and control on social media by Jeremy Weissman

In The Crowdsourced Panopticon: Conformity and Control on Social Media, Jeremy Weissman explores the role of ‘peer-to-peer’ surveillance through social media and how this is increasingly shaping our behaviour. This is a welcome addition to the scholarly work on surveillance and privacy, writes Matt Bluemink, with a clear, approachable writing style and a wealth of empirical examples. This review ...

Book review: Social media and the automatic production of memory: classification, ranking and the sorting of the past by Ben Jacobsen and David Beer

In Social Media and the Automatic Production of Memory: Classification, Ranking and the Sorting of the Past, Ben Jacobsen and David Beer explore how social media platforms are reshaping our processes of memory-making, with algorithms increasingly determining what is memorable to us. This exciting new book offers valuable insight into the implications of putting the production of our memories into the hands of automated systems, finds Matt Bluemink.

Book review: What do we know and what should we do about fake news? By Nick Anstead

In What Do We Know and What Should We Do About Fake News?, Nick Anstead explores what we mean by fake news and possible ways to address it. Situating fake news in its historical context and providing clear and brief summaries of the current scholarly work on the subject, this concise book will provide a solid touchpoint for people looking to understand one of the most pressing issues of our time, writes Matt Bluemink

Bubbles and particles in a cylindrical rotating flow

To predict the behavior of bubbles and particles moving in fluids, the hydrodynamics forces acting on them need to be known. They are often written in the form of dimensionless coefficients. For some forces, in particular the force at right angles with the velocity, i.e. the lift force, the parameterization of these coefficients is not clear. In this thesis the forces on bubbles and particles in a cylindrical solid body rotating flow are studied, both experimentally and numerically. \ud Experimentally the flow is realized by rotating a horizontal liquid filled cylinder around its axis. A bubble or a buoyant particle will reach a sable equilibrium position in the setup and from this position the drag and lift force can be determined. Some phenomena observed in the flow type under consideration differ from those in many other widely occurring flow types. Examples are a reversal on the lift fore at low Reynolds numbers for a bubble, a freely spinning sphere rotating faster than the surrounding fluid, a lift coefficient which rises with the Reynolds number for a particle, asymmetrical particles and bubbles that drift along the axis of a cylinder. The phenomena and the underlying physics explaining them are discussed

Virtuaalipeliympäristö strategisesti tehokkaan yhteistyön harjoittajana

Kirjoittaja tutki väitöstutkimuksessaan peliympäristöjä yhteisöllisen oppimisen rikastajina. Hänen mukaansa peliympäristössä syntyy vahva yhteinen tila, joka vahvistaa keskinäistä vuorovaikutusta ja yhteisöllistä oppimista. Hänen käyttämiään peliympäristöjä olivat eScape ja Gate for Collaboration. Tutkijan mukaan peliympäristö motivoi ja helpottaa hajautetuissa ryhmissä vaikeidenkin asioiden käsittelyä. – Johanna Blueminkin väitöskirja Virtually face to face : enriching collaborative learning through multiplayer games (Oulun yliopisto 2011).
