In this thesis we study four groups of students in grade 8, 9 and 10 when they try to solve a classical mathematical problem: Which rectangle with given circumference has the largest area? The aim of the study was too see how the students did to solve a mathematichal problem?The survey shows that students have rather poor strategies to solve mathematical problems. The most common mistake is that students don?t put much energy to understand the problem before trying to solve it. They have no strategies.

The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.

All companies face risk in their daily business. Internationalised companies tend to experience higher risk due to for example unfamiliar business environment than companies that act only on the national market. Estonia became independent as late as in 1991 and is therefore a new interesting market for many companies in neighbouring countries like Sweden. Risks that are most apparent for an internationalised company are political risk, currency risk, capital and interest rate risk, business risk and credit risk. Our intention of this study was to find out how Swedish companies acting on the Estonian market faced the different risks when entering the Estonian market and how they value the risks today.

The interest in small-scale electricity in Sweden has increased strongly in recent years. The interest is noticeable both among politicians to increase the share of renewables in the energy mix, and among electricity consumers to partially replace purchased electricity with self-produced. This has resulted in a significant increase of electricity production in low voltage grids in recent years, and the trend appears to continue in the coming years. The majority of the new production plants are solar cells, followed by wind turbines, and it is also in these the greatest efforts are made in this paper.Distributed generation is often seen as something positive since it will contribute to reduced transmission losses and reduced voltage drop in the networks, and that it increases the share of electricity from renewable sources. In cases where the grids are not strong enough, or in other ways not adapted to manage the installed production, power quality may be adversely affected.

Huvudsyftet med denna undersökning har varit att undersöka och jämföra lärares och elevers uppfattningar av lärares arbete med elevinflytande i engelska A-undervisningen på gymnasiet. Det andra syftet har varit att beskriva hur den nya ämnesplanen för engelska (Gy 2011) förändrats vis-a-vis ämnesplanen och kursplanerna för engelska (Gy 2000) och vad dessa förändringar kan få för effekt på lärares fortsatta arbete med elevinflytande i engelskundervisningen. Undersökningen genomfördes med utgångspunkt i följande huvudfrågeställningar: (1) hur förhåller sig lärare respektive elever till begreppet elevinflytande samt (2) vilka förändringar återfinns i de nya styrdokumenten för engelskundervisningen i Gy 2011 och hur kan det påverka lärares arbete med elevinflytande?Metoderna som tillämpats i undersökningen har varit kvalitativa semi-strukturerade intervjuer med lärare och elever, en enkätundersökning som riktades till elever och en jämförande textanalys av ämnesplanen för engelska Gy 2011 och Gy 2000. Dessa tre metoder valdes med utgångspunkten att kunna triangulera och på så vis jämföra det insamlade datamaterialet.

The following essay is a study about how migrant workers and immigration policies were discussed from Livsmedelsarbetareförbundets union press, Mål och Medel, to the members of the union between the years 1960-1973. To find this out I set these questions: What sort of information appear in Mål och Medel concerning migrant workers and immigrant policies, and how does this change over time? How does Mål och Medel present the immigrant workers opinions? The method for the study is based on analyzing articles, interviews and others texts found in Livsmedelsarbetareförbundets union press, Mål och Medel, and what they want to inform the members of the union about. The study?s results have found that during the early parts of the 1960s immigrant workers were not included in the union press at all. Towards the late 1960s the immigrants were discussed, but in a manner which implied that immigrants are naturally exploited and therefore must the immigration be controlled better. It also discussed immigrants had some sort of ?adaptation problem? to the Swedish norm.

This graduation paper treats e-mobbing via the different communication medias of the mobile phone. The purpose of the research has been to describe student?s experience of e-mobbing via the mobile phone?s different integrated functions as phone calls, sms, mms and e-mail.In this poll investigation asked 100 students of 15-20 years of age.The interviews made have shown that girls are more exposed to e-mobbing, e.g. indirect mobbing. In my research it is possible to see that girls are more exposed than boys to threats of violence via sms, the spreading of rumours and the danger of being called different things.It is also possible to see in the result of the interviews that the mobber wants to experience power, something which is not unusual in all types of mobbing.

The purpose of this study is to compare students (both male and female), from the Linnaeus University in Kalmar, about their perceptions with a particular focus on identity and self-esteem. In regards to the current societal problem concerning obesity and beauty ideals, this paper aimed to study the student?s opinions concerning health and diets in order to fully answer the purpose of the study. The theory used in this paper is in particular regards to identity and self-esteem. In order to answer the study questions, a qualitative approach was conducted in the form of various focus groups.

This paper aims to describe and elaborate on a recent discursive change within the new-age movement. Since the seventies and the publishing of speculative popular science books like The Tao of Physics by Fritjof Capra and The self-aware universe by Amit Goswami, the idea that quantum physics resonates with spirituality has become the topic of hundreds of books and movies.The quantum-spiritual discourse has three distinct ways to approach quantum physics in its discussion on spirituality: The parallelistic approach which emphasizes the similarities between eastern philosophies and modern physics, the monistic-idealistic approach which tells us that mind is the foundation of matter and the scientific spiritual approach which tries to explain spiritual claims scientifically. In the quantum-spiritual discourse, quantum physical phenomena (e.g. non-locality and entanglement) are being called upon to validate metaphysical statements. The primary assumption of the discourse is that the shift of paradigm due to the establishment of modern physics also is a shift of paradigm of spirituality.With the object to examine the common claims made in the discourse, cross-references between spiritual arguments and facts of quantum physics are being made.

Already in the late 1970´s it became clear that the traditional catalogs in libraries were not suited for children, neither their interests nor their way expressing themselves were accounted for. The goal of this thesis is to investigate if and how children?s OPACs (Open public access catalogs) interface design is at present adapted to the presumed audience of children. My method consists of literature studies and an investigation on the graphical interfaces in OPACs for children, according to the five criteria formulated by childrens library consultant Lena Lundgren and IT-consultant Kia Gumbel. The aims are to find out: a) what requirements for children?s OPAC interfaces and their usability are defined in literature and b) what the actual (real) features of the children?s OPAC interfaces are.

The purpose of this paper is to investigate how staff at secondary schools are thinking and reasoning about notifications to social services based on norm breaking behaviors in students. To find this out five qualitative interviews has been made with counselors in two public schools and three private schools in Örebro län. The results show that there is no clear definition of what norm breaking behavior is which making the reasoning difficult. There are clear procedures for the staff to dealing with norm breaking behaviors but they do not know when they will be applied. The decision to report behavior to the social service is usually not taken individually, it is a result of several people?s views and experiences.

The aim with this essay has been to see how students use drinking-songs and what function they have. I have also wanted to see how the traditions are carried on between the students. In order to do this, I have been observing three parties organised by three different student associations at Växjö University: Västkustens nation, Föreningarnas Festeri and Isterbandet. I have interviewed five people that have been attending the dinners. I have used Alan Merriam?s theory of use/function and made interpretations of his theory.

The study examines the massacre of the garrison of the castle of Kalmar in 1525 and its causes. The goal of the investigation has been on the one hand to elucidate the most probable sequence of events, and on the other to identify as many different plausible explanations to the massacre as possible. For this end, four contemporary sources have been examined and compared in their details. To enable a broad basis for interpretation, the author has consulted various works on the themes of warfare, soldiers and violence in the late middle ages and the sixteenth century. Apart from political aspects, the study highlights social and cultural conditions as important factors in explaining how the massacre could be carried out without provoking any single part of society.

Environmental enrichment is of high importance for zoos. Borås zoo asked SLU (Swedish University of Agricultural Sciences) for a student to perform a bachelor thesis for them. The task was to develop and evaluate environmental enrichment for their Humboldt penguins. A structure was made, consisting of a sinking skeleton with a floating bridge attached to it. It was presented in an area of the pool that the keepers had experienced that the penguins did not use to any extent.

According to the immigration service forecasts Sweden faces large refugee influxes in the coming years. This means that educators in the kindergarten, preschool and school, will meat children from the war torn countries. In this study, the purpose is to find out the educators different conceptions of war-affected refugee children, because my theory is that their beliefs influence their actions. I wanted to get answers to their beliefs about the difficulties or challengers that children and educators may be faced with. Furthermore, I wanted to know what educators envisioned about their own role?s importance to the war affected refugee children and their perceptions of the Swedish culture, environment, language and school.
