Bröstcancer drabbar dagligen ungefär 20 kvinnor i Sverige. Det är därför viktigt att se till att processen som dessa kvinnor och deras anhöriga genomgår fungerar väl och att upplevelsen är så bra som den kan vara under dessa omständigheter. Föreliggande projekt har genom ett tjänstedesignperspektiv undersökt hur bröstcancerprocessen upplevs av patienter. Detta med hjälp av intervjuer av både patienter och administratör inom bröstcancerprocessen. Dessa ledde fram till s.k. patientresor som beskriver hur processens olika steg ser ut men även hur patienterna upplevde dessa. Det skapades även patientresor utifrån hur landstinget vill och försöker få processen att se ut i dagens läge. Utifrån dessa patientresor hölls en workshop där fyra deltagare ifrån företaget Usify arbetade mot olika typer av visualiseringar av denna process. Visualiseringarnas fokuspunkter var väntan och känslor, då det hade framkommit under intervjuerna att väntan var det som upplevdes mest frustrerande och som den värsta delen under bröstcancerprocessen.   De idéer som framkom ur workshopen omarbetades sedan i två steg för att filtrera ut de designförslagen som ansågs mest passande. Dessa presenterades sedan för de tidigare intervjuade patienterna för att se om dessa överensstämde med deras upplevelser och ge dem möjligheten att ge sina åsikter. Resultatet visade att visualiseringarna kan kategoriseras i tre olika kategorier: statistik, verktyg och upplevelse. Dessa kategorier uppfyller separata behov och på så vis går alla designförslagen att använda i olika skeenden för olika ändamål. Något som upptäcktes under projektet var just hur väntan för patienterna resulterade i ett fel i tjänsten, de löften som dessa fick hölls inte av vården.   Inom tjänstedesign används ofta olika typer av visualiseringar för att upptäcka fel av den här karaktären. Problemet med väntan i visualiseringar är att dessa ofta är aktivitetsbundna, de vill säga att enbart aktiviteter avbildas. Väntan ses inte som en aktivitet och inkluderas därför sällan. Detta skulle kunna vara det som ligger till grund för att väntan förbises, i och med detta bör väntan inkluderas i visualiseringar. Förståelsen av väntan, som i bröstcancerprocessen upplevs som viktig för patienten, är något som kan leda till empati för patienten och ett resultat av detta projekt är att detta kan väckas med hjälp av visualiseringar av väntan.

The influence of tree age and microhabitat quality on the occurrence of crustose lichens associated with old oaks

Questions: How do tree age, microhabitat characteristics and epiphytic competitors affect the occurrence of crustose lichens associated with old oaks? How do microhabitat characteristics and microclimate affect the cover of competitors (bryophytes and macrolichens)? How do microhabitat characteristics cor¬relate with microclimatic variables? Location: Southeast Sweden. Methods: Eight crustose lichen species were surveyed on 165 Quercus robur trees, 17-478 years old, at three study sites. The occurrence patterns of these species were examined at two spatial scales: among trees and within trees. Occurrence patterns within trees were examined in 10 cm × 10 cm plots at all four cardinal aspects at different heights from 0.5 to 4.5 m above the ground. Results: At the tree level, age-related factors were the most important predictors of species occurrence. All species were more frequent on trees > 100 years than on younger trees. At the plot level, the frequency of occurrence increased with increasing bark crevice depth. The frequencies of all study species de¬creased with increasing cover of bryophytes. Bryophytes were in turn more frequent in plots that were exposed to rainwater and showed a low evaporation rate. Patches most exposed to rainwater were directed upwards, and the lowest evaporation rates occurred on the northern side of the trunks. Conclusions: For many crustose lichens the association with old oak trees seems at least partly to depend on their preference for the deep bark crevices that only occur on old trees. Trees represent epiphyte habitat patches that differ in size due to within-tree variability in habitat quality, such as bark crevice depth and microclimate. This study shows that variability at a finer scale, within habitat patches, contribute to explain species occurrence patterns at habitat patch level

Non-Orthogonal Density Matrix Perturbation Theory

Density matrix perturbation theory [Phys. Rev. Lett. Vol. 92, 193001 (2004)] provides an efficient framework for the linear scaling computation of response properties [Phys. Rev. Lett. Vol. 92, 193002 (2004)]. In this article, we generalize density matrix perturbation theory to include properties computed with a perturbation dependent non-orthogonal basis. Such properties include analytic derivatives of the energy with respect to nuclear displacement, as well as magnetic response computed with a field dependent basis. The non-orthogonal density matrix perturbation theory is developed in the context of recursive purification methods, which are briefly reviewed.Comment: 8 pages, 2 figure

The Judicial Expansion of American Exceptionalism

The percolation theory is established as a useful tool in the field of pharmaceutical materials science.It is shown that percolation theory, developed for analyzing insulator–conductor transitions, can beapplied to describe imperfect dc conduction in pharmaceutical microcrystalline cellulose duringdensification. The system, in fact, exactly reproduces the values of the percolation threshold andexponent estimated for a three-dimensional random continuum. Our data clearly show a crossoverfrom a power-law percolation theory region to a linear effective medium theory region at a celluloseporosity of ;0.7

Giant magnetic enhancement in Fe/Pd films and its influence on the magnetic interlayer coupling

The magnetic properties of thin Pd fcc(001) films with embedded monolayers of Fe are investigated by means of first principles density functional theory. The induced spin polarization in Pd is calculated and analyzed in terms of quantum interference within the Fe/Pd/Fe bilayer system. An investigation of the magnetic enhancement effects on the spin polarization is carried out and its consequences for the magnetic interlayer coupling are discussed. In contrast to {\it e.g.} the Co/Cu fcc(001) system we find a large effect on the magnetic interlayer coupling due to magnetic enhancement in the spacer material. In the case of a single embedded Fe monolayer we find aninduced Pd magnetization decaying with distance $n$ from the magnetic layer as ~$n^{-\alpha}$ with $\alpha \approx 2.4$. For the bilayer system we find a giant magnetic enhancement (GME) that oscillates strongly due to interference effects. This results in a strongly modified magnetic interlayer coupling, both in phase and magnitude, which may not be described in the pure Ruderman-Kittel-Kasuya-Yoshida (RKKY) picture. No anti-ferromagnetic coupling was found and by comparison with magnetically constrained calculations we show that the overall ferromagnetic coupling can be understood from the strong polarization of the Pd spacer

Skatterna och makten

Are there any limits to the tax-imposing powers of governments? One answer is to look for constitutional rules that are implied by democracy itself. For instance, the case for budgetary regulation could be extended to ban taxes that threaten economic growth and hence long-term public spending. A more fundamental question is whether might is right, i.e. if there is a "political obligation". Three fallacies are discussed; that people have a right to tax themselves, that majorities are always right and that individuals can't claim rights against the government. The conclusion is that the only philosophically sound ground for taxation seems to be consent by the individual. This is a line of reasoning that is more or less absent in the Swedish legal and political tradition, with the exception of the economist Knut Wicksell.legitimitet; beskattningsrätt; demokrati; rättigheter; samtycke; staten

First principles molecular dynamics without self-consistent field optimization

We present a first principles molecular dynamics approach that is based on time-reversible ex- tended Lagrangian Born-Oppenheimer molecular dynamics [Phys. Rev. Lett. 100, 123004 (2008)] in the limit of vanishing self-consistent field optimization. The optimization-free dynamics keeps the computational cost to a minimum and typically provides molecular trajectories that closely follow the exact Born-Oppenheimer potential energy surface. Only one single diagonalization and Hamiltonian (or Fockian) costruction are required in each integration time step. The proposed dy- namics is derived for a general free-energy potential surface valid at finite electronic temperatures within hybrid density functional theory. Even in the event of irregular functional behavior that may cause a dynamical instability, the optimization-free limit represents an ideal starting guess for force calculations that may require a more elaborate iterative electronic ground state optimization. Our optimization-free dynamics thus represents a flexible theoretical framework for a broad and general class of ab initio molecular dynamics simulations.Comment: 11 pages, 7 figure
