Cannibalism can have major influence on fish population dynamics. A prerequisite for cannibalism is that the cannibal and the potential victim meet, and besides density effects, the encounter rate between cannibals and their victims is therefore also largely dependent on habitat use and habitat heterogeneity. In this study I quantified and compared the potential for cannibalism in stream-dwelling European grayling populations in three rivers in Jämtland by means of habitat classifications. I also analyzed population dynamic consequences of varying the potential for cannibalism in terms of intensity, using a physiological structured population model. Findings based on habitat characteristics were that the potential for cannibalism is in general not favourable in these types of streams.

The purpose of this study is to discuss various approaches to group work and the importance of different approaches in relation to group work in schools. The study also looks at the results of the children working in different groups and constellations.This study is based on what previous research, literature and the tree teachers say about the subject group work and group divisions. Issues: Is there any kind of group work that always works? Does the structure of the tasks have any effect on the outcome? Is there any good reason to choose the teamwork approach that? The method I chose is a qualitative study with a phenomenological approach to the analysis. Three teachers were interviewed; result is presented in themes and concludes with a brief summary.

Abstract We have chosen to figure out why a majority in a home-help service group in west of Sweden is, or has been sick-listed. The purpose with our work has been to investigate our area to be able to come up with different factors which can have contributed to the high numbers of this particular group. We have worked with qualitative method and conversation-interviews to be able to answer our purpose at the best way. We had separate interviews with the ten employees at their work and these interviews we chose to record with a computer. The result we got were that the group had existed for about four years and since then, they have had several different directors.

The purpose of this thesis was to examine how two different groups use information strategies in their Facebook group activities. A qualitative study was made using interviews and a qualitative observation method. The observation groups consisted of two selected groups on Facebook and I interviewed three chosen participants of each group; a Gatekeeper, a Gateopener and a Lurker. Through the information strategies I examined the selected groups? information environments.

This candidate report describes how a group of students can develop a smartphone applicationwithout any prior knowledge in the field. To make the project more realistic there is also a clientwho has requests and wishes regarding the finished product.The document describes the methods used to produce the application and also includesexperiences that the group gained. How the interaction with the client has been performed togain a good understanding of what they wished the product to become is also accounted for.The research questions focus on how the development has proceeded and how one can learnsomething new in a relatively short timespan as a group..

In this study, five qualitative interviews were conducted, four of those with pupils and one with a teacher, in grade 9. Humans - a gregarious creature written in the context of status and hierarchy, aims to study how these students in grade 9 are grouped and how you look at each other in and between these groups and also in terms of status between and within the group. Using the concepts of identity, adaption, exclusion and the meaning of emotions with the chosen theoretical concepts by Goffman and, Elias and Scotson the purpose of this study has been answered. The results showed that the students were quite flexible between the groups in their class; most of them were part of a small group that consisted of their ?close? friends.

The purpose of this study is to investigate the unaccompanied children's experiences of the support offered at group homes intended for this group. The purpose is also to find out if they feel like the stay at the group home has prepared them for an independent life. The study has a qualitative approach and results collection occurred through semi-structured interviews. Seven young men aged 18-20 years were interviewed, all of them have lived for at least one year in a group home and are now living in their own apartment. The results have shown that the adolescents had both positive and negative experiences from their stay at the group home and that they have different views about whether they have received the support they need to cope independently.

Psychological research concerning correction of stereotypes has mainly focused on how individuals adjust their negative attitude towards the out-group due to the apprehension of appearing prejudiced in front of out-grouprepresentatives. This study though, does not deal with estimations of the qualities of the out-group; it deals with estimations of the qualities of the in-group. Does Swedes correct their estimations of their own group when the experiment leader is of another ethnicity and has a different colour of skin? The participants were students at Halmstad Högskola and they were all born and raised in Sweden. Half the participants got to meet a Swedish born, white skinned experiment leader, whereas the other group got to meet an African born, dark skinned experiment leader.

The purpose of this thesis is through a case study and a survey; to examine the most appropriate communication channels between a sender and a receiver. It also aims to make this relationship more effective.The following questions are to be answered:1. Which communication channels ought to be used to optimize the message from Skara Näringslivsoffensiv to its target group?2. Which communication channels is Skara Näringslivsoffensiv planning to use?3.

The purpose of this thesis was to analyse, model and finally generate dynamic vehicular motions in a train. The objective with the analysis was to find important motions for a realistic train experience. The motions from the analysis were then weighted against possibilities for generation in a motion platform.A dynamic motion model was created to model the selected motions. The model was implemented in a simulation environment, more specifically MATLAB/Simulink. The simulation environment was used to simulate the model and to generate outputs to control a motion platform.

My study was conducted to provide a deeper understanding of the identity of employee soldiers in the armed forces and their experience of their role in the military context. To describe and identify the soldier's identity formation, values and norms working in group processes are taken into account. As the individual identifies her or himself whit the group, the various phenomena as hostility to other military groups arise. The individuals weld together with other group members to form strong normative relationships within the group. Through a qualitative research approach eight soldiers in a regiment in western Sweden were interviewed, four of them were group executives or deputy group leaders and others were ordinary soldiers.

Bipolar disorder is a chronic affective disorder, characterized by episodes of mania and depression. Previous studies have shown beneficial results for CBT in conjunction with pharmacotherapy over pharmacological treatment alone. The aim of the present study was to evaluate a CBT treatment in group for patients with bipolar disorder, run by Norrlands universitetssjukhus. The treatment group consisted of pharmacologically stabilized patients (n=12) who received group CBT. They were compared to a control group (n=5) who received pharmacological treatment only.

A pilot study conducted on four patients, which we received from the Sahlgrenska University Hospital, who were all potential candidates for a cochlear implant. We fitted our test subjects with a pair of frequency compressing hearing aids called Phonak Naida V SP during the study and let them evaluate them for about seven weeks. Measurements made with monosyllabic words throughout the study showed significant differences in speech perception (p?0.05) compared to their regular hearing aids in 3 out of 4 cases. De-activation of the frequency transposed function showed significant decreases in 3 out of 4 cases compared to when it was activated.All test subjects were satisfied with the new hearing aids and chose to keep using them at the end of the study..

Our essay is about the grammar structure that the participants in A- and B- level of a school in the middle of Sweden, in the subject, Swedish as a second language, process. We have collected written productions from an A-level group and a B-level group and made a comparison between them morphologically and syntactically according to the processability theory by Pienemann.Processability theory was applied to Swedish by Pienemann & Håkansson (1999), with five steps in syntax and four steps in morphology. It turned out that the B-level group had much higher processing level of grammar than the A level group and one of the reasons for this can be that grammar is explicitly taught during the first year of studying Swedish as a second language in the school we have chosen to study..

This Masters Thesis considers tracking of ground targets. Since ground targets often are difficult to detect with sensors a track is easily lost in ground target tracking. The main question in this thesis is whether information on close targets and observations of them can be used to make the tracking more reliable. An algorithm using Kalman filters and JPDA-association to create a group track for vehicles travelling together has been implemented in Matlab. Using the state of the centre of the group the state of a vehicle in the group can be updated.
