Kommunal rekrytering i praktiken- platsannonsens betydelse vid tjänstetillsättningsärenden
This Paper examine how a municipality hire employees and in what way they use relevantlegislation in the recruitment process. The purpose of this paper is to clarify one specific municipality and their recruitment process, where the selection of the candidates is in focus of the process.The premiss is that municipalities can hire whoever they want, although some legislation needs to be considered. The principle of objectivity, the precedence and prohibition against discrimination are some restrictions municipalities must be aware of and not contravene.Further on candidates have an opportunity to require probation of the legality if they experience that mistakes have been made with the recuritment. However, only members of the municipality can emphasise this request.The municipalities job advertisements conformation and demands will be clarified in the paper. Job advertisements has a validity regarding disputes refering to discrimination because only the advertisement can justify employers procedure and choise.
En studie i användbarhet: En kritisk analys av användbarhetsstudier i biblioteks- och informationsvetenskap
Usability studies are not a central field of research in library and information science. Although literature in library and information science treats the importance of usable user interfaces quite extensively, the literature does not significantly treat potential problems in measuring usability. The aim of this master thesis is to investigate, through a critical analysis, the methods used when conducting usability studies in library and information science. The critical analysis is based on potential problems in measuring usability identified through a literature review from the field of studies Human-Computer Interaction, the concept of usabilitys original domain. The material which is to be analysed, is chosen from one library and information science journal Journal of the American Society for Information Science and Technology.
Sjuksköterskans erfarenheter av att kommunicera med patienter med afasi till följd av stroke : litteraturstudie
Dysfagi, sväljsvårigheter, förekommer i alla åldrar och vid en rad olika sjukdomstillstånd och skador. Evidensläget för de olika metoder som används för diagnostik och intervention vid dysfagi är i många fall osäkert. Syftet med denna studie var att ur ett evidensperspektiv granska forskningen med avseende orofaryngeal dysfagi hos vuxna. En omfattande databassökning genomfördes i PubMed mellan april och augusti 2011, begränsad till engelska och svenska studier, med deltagare över 19 år. Sökorden som användes var bland annat dysphagia (43 259 träffar), deglutition disorders (36 278 träffar), intervention, management, assessment, evidence, validity och reliability.

Hultsfredsfestivalen : Hur ett evenemang kan inspirera, påverka och utveckla en ort.
Purpose: The purpose with this study is to clarify what importance a co-occurrence event can have on a smaller town, and also what positive and negative consequences it can have on the town seen from a social, economic and political aspect. I will also look at what magnitude the festival have on the local commercial and industrial life and how it affects those who live there. I will also determent how the moving of the festival might come and affect the local businesses, the local population and the community it-self.Method: I will thorough-out this study work with qualitative research methodology. I will there-for process the empirical data that will be collected and used for this study from a qualitative research methodology point of view. I will likewise go through with two deep-going interviews with people well familiar with the subject to increase and strengthen the validity of my study.
Hur väl överensstämmer tandslitage på intra-orala foton med klinisk registrering?
Syftet: Målet med studien var att utvädera kliniska intraorala foton som diagnostisk metod för att bedöma tandslitage (attrition, erosion och abrasion) och jämföra dessa bedömningar med kliniska registreringar.
Material och metod: Studien genomfördes på Tandvårdskolan i Malmö, där man slumpmässigt valde ut 30 vuxna patienter. Dessa patienter undersöktes med avseende på tandslitage (attrition, erosion och abrasion) och kliniska foton togs. En månad efter kliniska registreringen gjordes en bedömning av de kliniska fotona, utan att ha kännedom om resultatet av de kliniska registreringarna. Båda undersökarna har på samtliga patienter utfört klinisk registrering och fotobedömning oberoende av varandra. Intra- och interobservatör överensstämmelse uppskattades genom Cohen?s Kappa- koefficient.
Resultatet: Intraobservatör överensstämmelsen mellan bedömningar av foton och kliniska registreringar var måttligt-till-god med ett P-värde på 0,039-0,046.
Att utvärdera vetenskapliga tidskrifter: En kritisk analys av Journal Impact Factor: en metod inom citeringsanalys.
The purpose of this Masters thesis is to make a critical analysis of Journal Impact Factor JIF. JIF is today the most widespread quantitative measure for evaluating scientific journals. Although it is internationally used and is considered authoritarian many problems have been observed. This has led to that the validity of JIF has been questioned. To identify JIFs limitations the following issues have been raised: Which are the problems with citation analysis? What criticisms have been directed towards Journal Impact Factor as a measure for evaluating scientific journals? The theoretical framework consists of theories about citation behaviour and a discussion about the characteristics of a scientific journal.
Francisella tularensis subspecies holarctica : the curious case of a water- and mosquito associated bacterium in Sweden
Francisella tularensis, the causative agent of the zoonotic disease tularaemia, is highly contagious and potentially fatal for a wide range of wildlife species of the northern
hemisphere, also humans. Although recognized as a pathogen for over 100 years, much still remains to be elucidated concerning the ecology and transmission of the bacterium, hence this literature overview aims at compiling data regarding the aquatic association and the role of
mosquitoes in transmission of Francisella tularensis subspecies holartica, the sole subspecies in Sweden. While a linkage between the bacterium and natural waters stands beyond dispute, there is no consensus in the literature concerning its potential as a reservoir. However, two
prevailing theories can be distinguished; one proposes the water association being mammaldependent and thus merely the result of contamination from semi-aquatic mammals living in
close vicinity to the water source. The other, quite contrary, suggests mammal-independence and hence that water, possibly in association with protozoa, serves as an environmental reservoir for the bacterium.

Bokbloggen i de litterära kretsloppen : En litteratursociologisk analys
This thesis explores the position of book blogs in the literary system through Robert Escarpit's socio-literary model of the book market. Simultaneously the thesis serves as a test for Escarpit's theory: by actively applying his theory and model to a very new and contemporary actor on the book market I hoped to reach or confirm new insights into the usefulness and validity of Escarpit's work for contemporary socio-literary studies.Three book blogs were selected for the analysis and interviews were carried out with the authors. The interview questions were formulated specifically for the purpose of extracting the kind of information necessary for an analysis using Escarpit?s theory. As a complement to the interviews, statistics on the type of books reviewed on the blogs were also compiled.
ADHD bakom bom och lås
How schools handles threat and violence among pupils could have an effect on the surrounding world, since schools reflect society at large. This study attempts to explore how this is handled within two schools, one secondary school and one upper secondary school. How do the schools work with violence and threats amongst pupils? Who is responsible for what? Is this work based on school guidelines? Why/why not? The theoretical starting-points have been Lundquists implementation-based control-model and an organizational point-of-view using theories about open and closed systems, primarily Meyer and Rowans neo-institutionalism. To gain validity, the study has been carried out by way of triangulation, i.e.
Utveckling och utvördering av statistiska metoder för att öka träffsäkerheten hos lokala vindprognoser
Wind is used as an energy source all over the world. To be able to use this effectively, there is a need for as good forecasts and forecast models as possible. One of these models is Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS®) that is used to calculate short time forecasts. This model is used here to calculate wind speeds at two different areas in Västra Götaland, Bengtsfors and Vänersborg. There are also wind measurements with SODAR stations for these areas.
Reliabilitets- och validitetsprövning av Modifierad Self-efficacy Scale för patienter med långvarig smärta
Syfte: Studiens syfte var att reliabilitetspröva stabiliteten för M-SES för patienter med långvarig smärta genom test-retest metoden. Syftet var även att undersöka samtidig validitet för M-SES, genom att utföra M-SES och SES mätt vid samma tillfälle.Metod: I studien undersöktes self-efficacy instrumentet M-SES på Uppsala Akademiska sjukhus, på avdelningarna för Smärtcentrum och Smärtrehabilitering. Frågeställningarna berörde vilken stabilitets reliabilitet mätt med test-retest som förelåg hos M-SES, samt vilken grad av samtidig validitet som förelåg för M-SES korrelerat med SES. Den slutliga undersökningsgruppen bestod i frågeställningen om stabilitets reliabilitet av 29 patienter (23 kvinnor, sex män), och i frågeställning om samtidig validitet av 22 patienter (17 kvinnor, fem män).Resultat: Vid prövning av stabilitets reliabilitet för M-SES visade resultatet en stark korrelation, med korrelationskoefficient 0,92 och p<0,05. Det förelåg även en god överrensstämmelse för test-retest undersökningen.
