Exact Probability Distribution versus Entropy

The problem addressed concerns the determination of the average numberof successive attempts of guessing a word of a certain length consisting of letters withgiven probabilities of occurrence. Both first- and second-order approximations to a naturallanguage are considered. The guessing strategy used is guessing words in decreasing orderof probability. When word and alphabet sizes are large, approximations are necessary inorder to estimate the number of guesses. Several kinds of approximations are discusseddemonstrating moderate requirements regarding both memory and central processing unit(CPU) time. When considering realistic sizes of alphabets and words (100), the numberof guesses can be estimated within minutes with reasonable accuracy (a few percent) andmay therefore constitute an alternative to, e.g., various entropy expressions. For manyprobability distributions, the density of the logarithm of probability products is close to anormal distribution. For those cases, it is possible to derive an analytical expression for theaverage number of guesses. The proportion of guesses needed on average compared to thetotal number decreases almost exponentially with the word length. The leading term in anasymptotic expansion can be used to estimate the number of guesses for large word lengths.Comparisons with analytical lower bounds and entropy expressions are also provided.

2083 – A European Declaration of Independence - An Analysis of Discourses from the Extreme

This paper analyses three of the dominating discourses Anders Behring Breivik used in his compendium, the official title of which is 2083 – A European Declaration of Independence, also known as Breivik's Manifesto. It is believed Breivik posted his Manifesto on the Internet shortly before the attacks in Norway in July, 2011. The number 2083 stands for the year when the "Western European Civil War" was expected to be completed, all traitors executed, and all Muslims deported from Europe. This article will discuss dominating discourses in the Manifesto, seen from a background of a European multicultural backlash, in which the political far-right movement is increasing. Furthermore, this article will end with a discussion of education and the importance of analysis of such phenomena within different subjects.

Skolan är en lättköpt arena - livskunskap i kritisk belysning

During the last decade a school subject with the designation of Life Competence Education ("Livskunskap" in Swedish) has emerged in many Swedish schools. The aim of this article is to describe and analyse the subject Life Competence Education, its historical and ideological roots and current place in the curricula of some selected schools. The article is based on analyses of policy documents, interviews and participant observations from fieldwork in two upper secondary schools and in one course for further training of teachers arranged by a municipality. Work by Foucault, especially on governmentality, is used as an analytic tool, as well as work developed from Foucault by Nicolas Rose and Stephen J. Ball. The analyses show that the subject Life Competence Education is constructed in many varied ways in Swedish schools due to different influences, both from the state, but also from private policy entrepreneurs (Ball, 2006). It is also shown that the SET-programme, which is only one example of programmes used for this type of education, is quite widely used in Life Competence Education in Swedish schools. In light of analyses from Foucault and Rose, I suggest that these programmes can be seen as the "psy", i.e. the "psychological domains" (Rose, 1999), entering into the educational arena and with the help of behaviouristic theories constructing "governable subjects" (Foucault, 1988, 1991). This raises questions regarding what kind of subjects are constructed in Life Competence Education, with what kind of methods, as well as how these methods are construed in the light of the Swedish National Curriculum

Debriefing in simulation conducted in small and large groups : nursing students’ experiences

The debriefing phase in human patient simulation is considered to be crucial for learning. To ensure good learning conditions, the use of small groups is recommended, which poses a major challenge when the student count is high. The use of large groups may provide an alternative for typical lecture-style education and contribute to a more frequently and repeated training which is considered to be important for achieving simulation competency. The purpose of the present study was to describe nursing students’ experiences obtained during the debriefing conducted in small and large groups with the use of a qualitative descriptive approach. The informants had participated in a human patient simulation situation either in large or small groups. Data was collected through the use of five focus-group interviews and analysed by content analysis. The findings showed that independent of group-size the informants experienced the learning strategies to be unfamiliar and intrusive, and in the large groups to such an extent that learning was hampered. Debriefing was perceived as offering excellent opportunities for transferable learning, and activity, predictability and preparedness were deemed essential. Small groups provided the best learning conditions in that safety and security were ensured, but were perceived as providing limited challenges to accommodate professional requirements as a nurse. Simulation competency as a prerequisite for learning was shown not to be developed isolated in conjunction with simulation, but depends on a systematic effort to build a learning community in the programme in general. The faculty needs to support the students to be conscious and accustomed to learning as a heightened experience of learning out of their comfort zone.

Att kvalificera ett samtalsuppdrag : Om ett utvecklingsarbete i speciallärarprogrammet

I denna rapport redovisas ett utvecklingsarbete som genomfördes vid speciallärarprogrammet vid Karlstads universitet läsåret 2010/2011. Enligt examensordningen är en av speciallärarens arbetsuppgifter att vara en kvalificerad samtalspartner. Vad som menas med kvalificerad samtalspartner är upp till varje lärosäte/ varje speciallärare att själv fylla med innehåll. Syftet med rapporten är att beskriva ett utvecklingsarbete och de erfarenheter som gjordes och därmed sätta ord på delar av speciallärarens yrkeskunnande som kvalificerade samtalspartners. Utvecklingsarbetets övergripande syfte var att pröva dialogseminarieformen för att fördjupa speciallärarnas yrkeskunnande i deras uppdrag som kvalificerade samtalspartners. Eller uttryckt med andra ord kvalificera ett samtalsuppdrag. I arbetet med dialogseminarier lyfts andra värden än de i utbildningssammanhang så vanliga; effektivitet, snabbhet, mätbarhet till förmån för långsamhet, eftertänksamhet och kanske ett gott omdöme. Efter en termins arbete med dialogseminarier kan vi nu dra slutsatsen att deltagande i dialogseminerier tycks ha bidragit till att: öka studenternas reflektionsförmåga öka deras förmåga att lyssna både inåt och utåt knyta förbindelser mellan det personliga och det professionella utveckla deras yrkesspråk och kanske deras omdömesförmåga.

Äldre i Värmland : Om hälsa, levnadsvanor och livssituation 2006

Landstinget har i samarbete med Karlstads universitet gjort flera befolkningsundersökningar i Värmland och publicerat rapporter om både den vuxna befolkningens och barns hälsa, senast med rapporten Värmlänningarnas Liv och Hälsa 2004. Någon befolkningsstudie av de äldres hälsa och livsvillkor har dock inte gjorts tidigare. Efter tre års förarbeten och samråd mellan landstinget, Värmlands kommuner och flera institutioner vid Karlstads universitet genomfördes den föreliggande studien av de äldres hälsa under senhösten 2006, i form av en omfattande postenkät. Urvalet utgjordes av 2500 slumpmässigt uttagna kvinnor och män som var 80 år eller äldre. Svarsfrekvensen var 60 procent, vilket får betraktas som mycket bra med tanke på att cirka 15 procent i denna åldersgrupp lever i särskilda boenden. Studien avspeglar således hälsan och livsvillkoren för de äldre. Överlag visar det sig att de äldre mår bra och har stor kapacitet att fungera som aktiva samhällsmedborgare. Samtidigt är det många som har kroniska besvär, med värk, syn- och hörselnedsättning, inkontinensbesvär etc. Det föreligger också en klar social gradient, där särskilt äldre kvinnor med arbetarbakgrund har både mer sjukdom och större ekonomiska problem än de övriga.
