Att möta de ensamkommande: En narrativ studie om civilsamhället och mötet mellan de frivilliga och de ensamkommande

Dagens flyktingkris är världens största sedan andra världskriget. Idag flyr människor sina länder från förtryck, krig och förföljelser och hälften av dem är barn. Antalet ensamkommande barn har ökat under de senaste åren och under januari – oktober 2015 sökte 23 349 ensamkommande barn asyl i Sverige.1 Regeringen har lyft fram betydelsen av det civila samhället både generellt och inom integrationso

Planet migration in evolving protoplanetary discs

En nyfödd stjärna är omgiven av en disk som består till mestadels av gas med en liten andel grus, en så kallad protoplanetarisk disk. Det är i den här disken som planeter bildas, och likt planeter så roterar den runt solen. En viktig egenskap hos den protoplanetariska disken är att den förändras med tiden. Stjärnans gravitation drar till sig material från disken, vilken gör att den blir mindre ochThe rate of migration and accretion onto protoplanets is greatly influenced by the structure of the surrounding protoplanetary disc. This structure changes with time as the disc evolves on a million year timescale, implying that the process of planet formation might look very different depending on when it was initiated. Further on, the evolution of the disc structure is affected on smaller timesc

Partitioned Multirate Time Integration for Coupled Systems of Ordinary Differential Equations

Tänk dig att två musikanter ska öva ett musikstycke tillsammans. De kan var sin del för sitt instrument, men de har aldrig spelat tillsammans. Nu är det så att musikanterna sitter i två olika rum och inte kan höra eller se varandra under inspelningen, utan de kan bara höra slutresultatet. Det låter såklart inte alls bra och kommer krävas många försök innan de börjar bli samspelta. När musikerna fåIn this thesis a new method for the numerical solution of coupled systems of ordinary differential equations is investigated. To understand this new method, the workings of existing Waveform iteration methods, in particular the Jacobi and Gauß-Seidel methods were explored first. These methods were introduced to be able to exploit multirate behaviour in systems and use an iterative procedure to suc

Defective functioning in GABA:ergic interneurons has been linked to undesired desynchronous firing in neural signals as a consequence of these interneurons firing too infrequently or not at

Kan inte ni gå in i byggis? Förskolepedagogers interaktion med förskolebarn utifrån ett genusperspektiv.

Många barn i Sverige tillbringar en stor del av sina dagar på förskola där många av deras sociala erfarenheter och utveckling äger rum. Kognitiv social inlärningsteori förespråkar att barnet lär sig genom att imitera och härma vuxna och utifrån detta skapa kognitiva scheman som används för att tolka omvärlden. Barnen härmar de vuxnas beteende, vilket gör att pedagoger på en förskola besitter en vi
