An old and well known problem in sawmilling is to determine which dimensions /products those are most profitable to produce. Existing optimization models maximize the value of the log. In other words, based upon the market prices of the dimensions the models calculate the best way to split the log. Yet there is a great uncertainty if the most well paid dimensions really are the most profitable to produce. The costs of the process from lumber to sawn products are hard to determine and are therefore often left out from the optimization process. In this study the economic contribution of different dimensions/products are analysed.

Burkina Faso as well as most sub-Saharan African countries struggle with providing food for a fast growing population. The dominating farming system is agroforestry parklands. Agroforestry parklands can broadly be defined as areas where scattered trees occur on farmlands as a result of selective clearing. The presence of trees in crop fields may in the long term have a positive effect on the production of annual crops. It is commonly discussed, but not proven, that the presence of trees leads to increased groundwater recharge due to higher infiltration capacity of the soil.

Early intervention is important on different levels and must be justified as a social and economic long-term investment. There is no doubt about the importance of early detection when helping children/students in need of support. What kind of support that is deemed suitable and who provides the support can be viewed from different perspectives and with different approaches. Seen from a relational perspective the special education process is a long-term process and affects not only the individual but the whole school culture and systems may need changing. This study intends to describe the importance of the learning environment and what efforts are initiated early for students in need of support from the special education point of view.

There are differences today amongst psychoanalysts regarding if psychoanalysis should limit itself to being exclusively a hermeneutic discipline or if psychoanalysis should find points of contact with neurobiology. The purpose of this essay is to touch upon the larger issue that creates the different points of view: Can psychoanalysis become enriched by finding points of contact with neurobiology, and should psychoanalysis be regarded as belonging to a broader scientific field than being exclusively a human science? The question at issue is: Can modern neurobiology contribute to a development of the psychoanalytic concepts; compulsion to repeat, transference/countertransference and talking cure? The method used is a literature study. The result shows that: Freud?s theories regarding traumatic compulsion to repeat can be linked with LeDoux?s theory of "emotional memory".

The aim of the study is to describe social workers discretion when it comes to the relation between children placed away from home and their biological parents.The study describes how the social worker designs the contacts with the biological parents, for instance the extension for the actual meeting. The results are based on six interviews conducted with social workers who work with foster children. They have responded to questions related to the contact between children and their biological parent. The questions are based on eight vignettes. The contents of the vignettes show different conditions that affect the contact, for example age and foster care attitudes The results of the study have been compared to other previous research in discretion of the social worker and contacts between children and their biological parents.In summary the study shows that there is  high degree of independence for the social workers designing their work and that their level of discretion.

The purpose of this study is to examine how teachers and parents are communicating with each other in a foreign area. In case of obstacles in the communication, this study will examine how the preschools create opportunities to solve the problem. This study will also look closely at this relationship from an intercultural communication.This study is based on interviews. My informants are four teachers and four parents, one of the parents is Swedish and the other three have different ethnic and culture backgrounds.This study has reached to several results. The interviews with the teachers have shown that they are unsatisfied with their relationship with the parents because there are two factors that result to their communication difficulties.

Projects to equip every student and teacher with a laptop, with the intention to improve academic results, have rapidly spread through the country. New technology, new contents and new ways of learning have changed the learning envi-ronment. The school library, being a part of this environ-ment, faces the same changes and challenges.The purpose of this thesis is to study how the school library is being affected when a One-to-One project is carried out in a learning environment. The research questions concern how the school library is viewed within the organization and also how the change affects both the school library and the school librarian.The empirical material of the thesis includes five qualitative interviews carried out on location, at a single selected school. The interviews are followed by a study of relevant documents, all produced within the organization.To understand the organization in which the school library operates, as well as the school library itself, I chose to divide the theoretical approach in two: Christensen?s et al.

Detta examensarbete har gjorts i samarbete med JM Entreprenad som är ett helägt dotterbolag till JM AB. JM AB är ett av Sveriges största byggföretag. Arbetet har gått ut på att hjälpa JM Entreprenad Region Hus med att undersöka hur erfarenhetsåterföringen mellan Kalkylavdelningen och produktion ser ut samt att komma med förslag till förbättringar.Erfarenhetsåterföring handlar om att samla in och återanvända de erfarenheter och kunskaper som kommer från olika delar av organisationen för att sedan ha dessa som utgångspunkt för förbättringar av det framtida arbetet.Det finns i nuläget inga fastslagna rutiner för hur denna erfarenhetsåterföring skall genomföras vilket är en stor brist i organisationen. För att förändra detta bör företaget sträva efter att bli en lärande organisation och skapa tydliga rutiner för hur detta arbete skall läggas upp..

The main focus of this study was to investigate how Swedish military veterans experience that events during an international service affect them after completed mission. This also includes the contact with their relatives. Secondly, this study deals with the course of the crisis, personal defense mechanisms, cumulative stress and post-traumatic stress syndrome (PTSD).The study was performed using a qualitative method and comprises individual interviews with six Swedish veterans. The responders were all men of different military positions, who participated in one or more international missions during 1993 to 2011.The results of this study show that, according to the veterans, the return back home is the most strenuous part of an international mission. With all the new experiences that an international service brings fresh in their memories, it is hard to re-adjust to the life of a civilian.In connection with the return back home, different degrees of stress reactions were also commonly seen, for example sleep disturbance, restlessness and exhaustion.

The purpose of this study is to look into how detained swedish juveniles, in the ages between 15 an 20, experience time in custody. The primary questions are; To what exctent do juveniles understand their situation? To what exctent can juveniles handle their situation? Do the juveniles find meaning in their situation and if so, what aspects of the detention is considered meaningful? The study is based on seven qualitative interviews with young men detained at a youth custody ward at Kronobergshäktet in Stockholm. The theory used to analyze the interview results is Antonovskys theory of sence of coherence (SOC). A salient feature in the young mens experiences was that all of them had the ability to regard some of the aspects of the detention as meaningful.

In this essay I examine if socio cultural theory is present for teachers when pupils and students are using computers in class, especially when using blogs as a tool for learning. The aim of the essay is also to examine if blogs among pupils in class can promote peer support, co-operation and reflective dialogue, and in that case in what way. The essay consists of two studies, one small interview study and one literature study.  The interview study is made with the qualitative method phenomenographic analysis, presenting four Swedish teachers who have much experience using blogs in education. The aim of the literature study where some national and international research studies of relevance are presented, is to broaden the perspective.The result of the interview study shows that a socio cultural theory is highly present among the teachers who already use blogs in education. In addition, those teachers experience that the blog in the classroom supports dialogue and co-operation among the pupils.  In contrast, the literature study shows that most teachers in Sweden who made their pupils work with computers in classroom seem to let their student work alone, without guiding them and without creating co-operation or dialogue in the classroom.

Choosing the right user experience evaluation method can be difficult, choosing the right one for mobile user experience can be even more so. One major cause is that mobile usage is context dependent. Another contributing factor is that there is not one widely adopted theory or framework for user experience due to its complexity.The purpose of this study was to evaluate an existing method artifact in its feasibility for evaluating mobile applications. The chosen method, AttrakDiff2 is a self-reporting semantic differential questionnaire to evaluate the user experience of an interactive product, based on its hedonic and pragmatic qualities.A study was conducted where the participants assessed one mobile and one web application, which were later rated with AttrakDiff2. The completion of the questionnaire was conducted as a think-aloud session subsequently followed by an interview.The results suggest that the participants experience was affected more by the evaluated application style than the different platforms.
