Förändringar i vegetationens sammansättning efter en våtmarksrestaurering : Changes in the vegetation composition after a wetlandrestoration
The loss of such great wetlands, which has arose in Sweden the last decades, has created a situation that threats both the function and the biological diversity within the wetlands. Many ecological niches can be found in the wetlands and it is one of the habitats where most different species exist. In the 17th Century people started to ditch damp environments, such as bogs, to create a productive cultivated ground. Further ditches were made when the forestry gave large economical profits. The wetlands were impoverished from both groundwater and nourishment, and this led to a great loss of species.In a corporation with WWF and Skogsstyrelsen in Arvika, the University of Karlstad has participated in the Laskerudproject, a hydrological restoration-project in a forest landscape.
Hur barn i årkurs 3 uppfattar syftet med Nationella provet
This is a study of the national test in 3rd grade. The national test is obligatory and is conducted in 5th and 9th grade, but since the spring of 2009 the tests also become mandatory in 3rd grade. The case study of this research is to find out how children in 3rd grade perceive the purpose of the national test. The survey should also clarify how students think and feel about the national test, and how they feel before the national test and after they have finished writing the test. Has the test positive or negative influence on children? The survey will also show how much teachers clarify what the significance of the national test is for the students.
Mätning av barns oro vid undersökning eller behandling på sjukhus
Att barn kan vara oroliga vid sjukhusvistelse har framkommit i flertalet studier. Oro kan påverka smärta och tvärtom. Minnen av smärta kan skapa oro. För att bedöma barns oro finns ett par instrument. Ett av dessa är State Trait Anxiety Inventory for Children (STAIC-S), en enkät med 20 påståenden, där barnen får fylla i hur de känner sig.
Arvets betydelse för mjölkkors beteende :
It becomes more important to consider different behaviour traits in the selection for dairy cows to be suitable in the production systems of today. The purpose of this investigation was to study the genetic background to behavioural traits and the heritabilities for temperament, rank order, aggressiveness, feeding behaviour and for learning behaviour. Moreover, the genetic correlations to other traits were studied. To be included in a breeding programme a trait needs to have enough genetic variation, a moderate to high heritability or to be correlated to another measurable trait. Behaviour is a quantitative trait affected by many genes and the environment.
Strauss test, vara eller icke vara?
Att genomföra ett test som alltid ger samma resultat kan i längden kännas omotiverat. Strauss test är ett test som funnits länge för att testa stålets känslighet mot interkristallin korrosion. I detta arbete har Strauss test utvärderats i syftet att få fram ett underlag som kan användas för att starta diskussioner om en förändring i provningsmetodiken. Anledningen till att en förändring behövs är att alla dessa, ej informativa, tester kostar pengar. För att få fram underlaget har en litteraturstudie och experiment genomförts.

The purpose of this thesis is to study what motivational factors motivates the staff in the public elderly care and to investigate how the staff ranks the different motivational factors and if the rankings differ depending on gender, age, education, type of employment, time of employment, employer, income and ethnic background. The thesis is based on a questionnaire study with a total of 97 participants. The questionnaire was constructed with the help of prior similar studies conducted in the USA and Malaysia over a sixty-year time period. These studies are then used to analyze the results. The participants in our thesis were given ten motivational factors to rank according to what they believed motivated them the most.
Friluftsliv och miljömedvetenhet bland ungdomar
Att vara ute i naturen medför inte bara rekreation utan kan kanske även bidra till en ökad miljömedvetenhet. Dock visar forskning skilda resultat i frågan. En ökad miljömedvetenhet är är viktigt för att främja en hållbar utveckling, därför är det intressant att undersöka hur ungdomar ställer sig till miljöfrågor. Syftet med denna studie var att undersöka om det finns ett samband mellan olika friluftsaktiviteter och miljömedvetenhet hos ungdomar. I studien inkluderades enkäter (n=433) från högstadie- och gymnasieungdomar i en medelstor kommun i södra Sverige.

Testeffekten som medel för att förbättra läsförståelse?
Swedish school children exhibit deteriorating knowledge results in terms of reading comprehension. Previous research shows that a method to increase the level of knowledge is the use of evidence-based learning techniques. Test based learning generates what is commonly referred to as a test effect, which proved to strengthen the relationship between learning and memory, as well as being applicable to various test formats. The purpose of this study was to investigate whether test based learning, in terms of learning english words leads to increased performance in a reading comprehension test, more specifically a cloze test. The study was based on a within-group design and was conducted three times over four weeks.
Teststrategier och användning av testautomation : En studie utförd på företaget Extenda AB
In today?s IT world where software is constructed in a rapid pace, testing has become a crucial area to master when testing has to be done at a greater speed. To still be able to handle the demands of high quality software, companies have to spend more resources on testing and introduce test automation. By automating test cases the testers can gain time which they can spend on doing more complex testing and thereby increase the quality of the software.In this thesis we have helped Extenda AB, who delivers systems to retail companies, to introduce test automation in one of their customer specific projects. This has been done using their own in-house ?capture/replay? tool ECP (Extenda Cashier Player).We have also derived a process that explains how Extenda can introduce test automation on other customer projects.
Sälja eller låna ut, är det skillnad? - En experimentell komparativ studie av återvinningseffektivitet i bibliografiska databaser.
The aim of this thesis is to answer whether a group of databases dedicated to selling books or a group of databases dedicated to lending books is more efficient. The measurements used to determine the efficiency of the two kinds of databases are Cumulated Gain and precision in modified versions. The inquiry has been conducted thus that the same 18 queries have been put forth to six databases and these results have consequently been judged according to relevance on a 4-graded scale by five respondents. The rankinglevels have then been merged to one average value per respondent and ranking. These values have then been used to determine CG/iCG/nCG and P@n per query, rank 1-10, per database and per group (the groups being STORE (BUTIK) and LIBRARY (BIBLIOTEK).

Hållbarhetsredovisning : En studie av Vattenfall AB i ljuset av GRI
This essay is about democracy and how a democracy index can be used as a tool to illustratethe gap between reality and ideal. The purpose of this study can be expressed by two researchquestions: Does the Economist Intelligence Unit's (EIU) democracy index illustrate thedistance between reality and the ideal of democracy presented by Dahl? and Can the EIU'sdemocracy index be modified by a) internal adjustments and b) using the variables includedin World Economic Forum?s (WEF) equality index?By using a combination of theories (Dahl?s theory of democracy, Rawls theory of justice andchosen theories critical to liberal democracy) as an analytical framework the following twoquestions have been answered:1) Which of the variables included in the EIU's democracy index have the potential to capturethe level of political equality?2) Which of the variables included in the WEF?s equality index have the potential to capturethe degree of political equality?By using a quantitative method the study?s third and last question has been answered:3) How strong is the rank correlation between the EIU?s democracy index and the WEF?sequality index, that is; how strong is the rank correlation coefficient (rho)?The data presented by the WEF?s equality index indicate that women are systematicallydiscriminated against as a group. From a democratic perspective the EIU may need tomeasure inequalities at a group level in order to capture the lack of political equality betweenindividuals. By reformulating some of the EIU?s variables, by revising the EIU?s point systemand by using the variables included in the WEF's equality index to extend EIU?s democracyindex, the chances of capturing the gap between reality and the ideal of democracy presentedby Dahl would likely increase..
