Personlig utveckling under polisutbildningen

Syftet med arbetet är att belysa de eventuella förändringar studenter på polisutbildningen vid Umeå universitet genomgår. Människor, platser, behovet av att passa in och grupper påverkar oss hela livet och enligt vår mening har de flesta i vår umgängeskrets på ett eller annat sätt förändrats sen dem kom in på polisutbildningen. Vad anbelangar arbetets del om personlig utveckling är den avgränsad till att endast undersöka den personliga utvecklingen hos polisstudenter vid Umeå Universitet, vi har också bara riktat in oss på studenter som går i termin 4. I undersökningen har vi att använt av oss enkäter bestående av 44 frågor som sedan slumpmässigt delats ut till 39 studenter. Angående de förändringar vi kunnat påvisa var vårt mål att sedan försöka koppla dem till olika teorier om grupper. Då vissa av dessa förändringar hade att göra med polisens kåranda ville vi även belysa eventuella kopplingar till denna. Utifrån analysen så har vi kunnat se sammanband med de teorier vi valt att fördjupa oss i. Stora delar av resultatet blev som väntat medan vissa svar var överraskande och inte alltid positiva

Gelling kinetics and in situ mineralization of alginate hydrogels:A correlative spatiotemporal characterization toolbox

Due to their large water content and structural similarities to the extracellular matrix, hydrogels are an attractive class of material in the tissue engineering field. Polymers capable of ionotropic gelation are of special interest due to their ability to form gels at mild conditions. In this study we have developed an experimental toolbox to measure the gelling kinetics of alginate upon crosslinking with calcium ions. A reaction–diffusion model for gelation has been used to describe the diffusion of calcium within the hydrogel and was shown to match experimental observations well. In particular, a single set of parameters was able to predict gelation kinetics over a wide range of gelling ion concentrations. The developed model was used to predict the gelling time for a number of geometries, including microspheres typically used for cell encapsulation. We also demonstrate that this toolbox can be used to spatiotemporally investigate the formation and evolution of mineral within the hydrogel network via correlative Raman microspectroscopy, confocal laser scanning microscopy and electron microscopy

Money for Nothing: Everyday Actors and Monetary Crises

Why do monetary unions fail? Structural approaches that focus on shifts in the distribution of capabilities ascribe non-elites limited agency to influence large-scale political and economic change. Existing agent-centred approaches tend to simplify the social dynamics of the everyday politics of money by concentrating on how elites determine formal changes within monetary systems. Answers to this question from a material-based perspective often point to a breakdown in elite political support, driven by actors’ material incentives to cheat on their multilateral commitments rather than cooperate to overcome the collective action problem that a monetary union entails. Recent ideational perspectives have focused on the role of shared economic ideas among elites, as well as elite struggles over national identity, as crucial ingredients in the construction, maintenance, or failure of a monetary union. While drawing on the insights of rationalist and constructivist theories, this article uses a historical sociology approach to argue that the everyday actions taken by non-elites as survival strategies in a monetary crisis provide an important additional ingredient for understanding monetary system change. This approach is illustrated through a case study of the collapse of the ruble zone monetary union over 1991–1993
