Om matematikundervisningens svåra konst. Ett sätt att undervisa abstrakt bevisföring

Tree fiber lengths controls properties like strength and smoothness in paper and other wood products. For forest researchers it is of interest to be able to determine the fiber lengths in standing trees. Mo?rling et al. (2003), among others, have developed methods to estimate fiber length distributions in standing trees without damaging them.

Träddelsuttag eller massavedsuttag i förstagallring?

The purpose of this study is to compare the economic differences between withdraw of forest fuel and withdraw of pulpwood in first thinning, to see which method gives the maximum profitability (income - cost). Another purpose is to investigate the economic impact of the thicket cleaning. The study compares four different methods: i) pulpwood output with thicket cleaning, ii) pulpwood output without thicket cleaning, iii) forest fuel output with thicket cleaning and iv) forest fuel output without thicket cleaning. The study was conducted in a 30-years old stand, dominated by spruce, outside Harg in Uppland. The method that generated the best economic net income was pulpwood without thicket cleaning. It generated a positive net of 1,383 SEK per hectare. Forest fuel output without thicket cleaning also generated a positive net in 720 kronor per hectare.


Varför slår han? : En integrativ forskningsöversikt om de bakomliggande orsakerna och vad som kan göras åt det

Today equal representation between the genders in parliament is something to be desired. One way to reach the goal of equal representation is by using quotas. The purpose of the study is to research the lack of equality in elected institutions by using a perspective on qoutas.  The study also seeks to find answers to if using quotas is a good method according to gender studies. A text analysis is being used to find reasonable solutions to the study´s presented complivations.  By analyzing different texts about quotas some of the more common arguments in the discussion about using quotas in parliaments were highlighted. Some of the more frequent arguments to implement quotas are that it would be more just but also that women and men may have different interests, experiences and therefore equal representation would be a question of resources.

Självförfattning, läckage och olikhet : Om att kombinera kvantitativ metod och queera teorier i sexualitetsstudier

The aim of this study is to combine queer theories with quantitative methods. In social sciences, queer theories are being widely and increasingly used. Quantitative method is also widely used, and as a traditional method it can be regarded as a cornerstone in social sciences, sociology in particular. However, the two perspectives, queer theories and quantitative method, seem at a first glance to be very different in their understanding of social phenomena. Queer theories have, with some exceptions, mainly focused on qualitative research concerning such phenomena as sexuality, while the field of science is quite diverse.

Automatisk mätning och detektering av röjande signaler

This master thesis has been performed at Sectra Communications AB in Linköping where they manufacture electronic encryption devices. In cryptology it is essential that an eavesdropper cannot find the plain text. To assure that a system is safe, all devices are thoroughly examined so that they don?t emit any secret information, so called Compromising Emanations (CE). This is done by comparing the secret signal with measured signals on the screen of an oscilloscope, a process that is very time consuming and furthermore, the risk of missing compromising emanations is high.

Hur formas ett inlärningsklimat som är framgångsrikt över tid? : En observationsstudie om fotbollstränares beteenden och träningsaktiviteter

Aim and research questionsThe over-all aim of this study was to gain insight info how two male coaches of a specific soccer team behave in a practice environment with regards to educating the players.More specifically, the study sought to map the extent to which said behaviour matched two specific methods of learning; these being Teaching Games for Understanding (TgfU) and Enhanced Guided Discovery (EGD). Research questions: (1) Do the coaches employ the methods and guidelines, which are outlined in the educational plan provided by the soccer association? If so, what form does this application take in practice? (2) To what extent and in what ways do the coaches utilize feedback and questioning techniques in the education of players? (3) What similarities and differences in behaviour can be identified between the chosen soccer team?s two coaches?Method: The data for the study was collected through field observation. The subjects were two youth elite soccer coaches and observation of these coaches took place during five regular practice sessions on the soccer field. All data gathering and analysis were carried out using a modified version of the Coach Analysis and Intervention System (CAIS).

The aim of my thesis is to obtain knowledge of textile wastewater and textile sludge from an environmental perspective, which can be used as a basis for the  ?Sweden Textile Water Initiative? guidelines for a sustainable sludge management. In my study I have mainly focused on textile dyes, salts and metals and their routes during wastewater treatment.This paper is partly a literature review, which I began by identifying the pollutants discharged from each textile process. Then I studied wastewater and sludge quality, environmental aspects, possible treatment and recycling methods. I have also tried to find existing type of guidelines in order to make comparisons.

Energieffektivisering i offentliga byggnader : Jämförelse i elanvändning för ventilation med olika luftflödesstyrsystem

I got interested in this subject when I came in contact with Västtrafiks new paymentsystem myself during my visits in Gothenburg. I suspected problems with the informationmaterial regarding it and others seemed to share my opinion that the payment system wasdiffcult to understand. When I contacted Västtrafik and asked them about the paymentsystem they confirmed that some understanding diffculties had occurred. With thatconfirmation I decided to make it my project to look in to the matter.Some methods were used to identify the problems. The methods could again confirm thatthere were some problems with the payment system and that the information material wasa vital reason.

Ur askan i elden? : Om psykologiskt arbete med asylsökande barn

This phenomenological study explores the mental health problems of asylum- seeking children in Sweden and highlights possible ways of meeting their needs. Open interviews with 13 clinically experienced psychologists were conducted.The results of the analysis suggest that experiences of trauma and separation, the child's developmental level, parental functioning and family dynamics contribute to the mental health problems of asylum- seeking children. When meeting these children the psychologists continuously face ethical dilemmas since the asylum-seeking process seems to aggravate the problems as well as complicate the use of traditional interventions. Promoting structure and activity, normalizing symptoms, educating about trauma and crisis, sharing and accepting anxieties and sometimes thoroughly working through traumatic experiences are treatment strategies found clinically useful. Systematic follow-up studies are needed to decide the effects of these interventions..

Specialpedagogers arbete i fo?rskolan med fokus pa? inkludering. Special educators work in preschool with focus on inclusion.

How do special educators work to include children with special needs in preschool? That was the question that our thesis proceeded from, and the purpose was to get an insight in the methods used by the special educators to achieve inclusion. Our questions were: ? Is Swedish preschool a place for inclusion? ? How are special educators work organized and focused? ? Which experiences do special educators have working with children with special needs in preschool, and what role do they mean that inclusion plays in this work? Our procedure in this enquiry was to perform semi-structured interviews with 5 different special educators in two different cities. Interpretation and analyis proceeded from three different theories: Urie Bronfenbrenner?s ecological systems theory, John Bowlby?s theory of attachment and Karsten Hundeide?s sociocultural theory. The result showed support for the idea of the Swedish preeschool as a place with many opportunities for inclusion. We have also seen how both money and political decisions has an impact on which possibilities the preschools receive to work with inclusion. In addition it became apparent that the methods used by special educators differed depending on both cities and districts.

"En riktig våldtäkt" : - en kunskapsöversikt om föreställningar om våldtäkt

This essay is a selective review of Nordic literature with the aim to explore contemporary conceptions of male-on-female rape, to increase the understanding of how these can construct ?a real rape?. To achieve this two questions were formulated: What circumstances can cause an incident not to be defined as rape? What circumstances can cause an incident to be defined as rape? Searches in international and Swedish databases led to initial selection of peer-review journal articles and dissertations that were reviewed against set criteria. These criteria were met by 8 studies, that were assigned codes, from which comprehensive categories were developed.
