The aim of my study is to investigate how last year students in upper secondary schoolunderstand certain mathematical concepts, in particular the unit circle and its trigonometry.I have used intentional analysis to interpret student?s actions when they solve certain tasks onthe basis of a cognitive, situated and cultural context.Interviews with four university teachers in mathematics about the unit circle, trigonometry,and mathematical understanding, serve both as background for the study and as basis for adiscussion, where I relate students understanding to what the teachers want new students toknow about these concepts when they begin university studies in mathematics.The students were arranged in three groups with three students in each group. Each group waspresented with two tasks, one in which they were asked to calculate the cosine values for onepointed, one blunt and one straight angle, each located in a separate triangle. They were alsoasked to decide whether the points (0,71; 0,71) and d (1 2 , 3 2 ) are located on the unit circleor not.My conclusion is that students mainly have an operational conception of the unit circle andtrigonometry. The lack of structural conceptions result in difficulties in seeing connectionsbetween the concepts in unfamiliar situations.

Confrontation naming is commonly used in speech and language pathology to diagnose neurogenic communication disorders and evaluate naming ability. The existing Swedish assessment instruments for adults consist of pictures depicting nouns. In this study, parts of the instrument An Object and Action Naming Battery were used, containing pictures depicting both nouns and verbs. The study?s purpose was to explore the degree of difficulty in the material, based on the naming of the participants, and examine whether different variables correlate with the results in confrontation naming.

En god arbetsmiljö är en lagstadgad rättighet för arbetstagaren enligt Arbetsmiljölagen. Arbetet med att säkerställa en god arbetsmiljö kallas arbetsmiljöarbete och är en nyckelfaktor för att skapa hälsosamma och attraktiva arbetsplatser. Medarbetarundersökningar är en undersökningsmetod i det systematiska arbetsmiljöarbetet men kan också användas i syfte att ta reda på medarbetarnas uppfattningar om sin arbetssituation med målet att skapa verksamhetsförbättringar.I denna studie har syftet varit att undersöka vilken roll som medarbetarundersökningen spelar i chefernas arbetsmiljöarbete. Studien undersökte hur cheferna arbetar med arbetsmiljöarbete och hur arbetet med resultatet från en medarbetarundersökning genomförts. Studien genomfördes på en funktion med tre organisationsnivåer och bygger på 12 kvalitativa intervjuer med funktions-, avdelnings- och enhetschefer.Studien visar att medarbetarundersökningen spelar en viktig roll i chefernas arbetsmiljöarbete på alla organisationsnivåer både som diskussionsunderlag i ledningsgrupper och i dialogen med medarbetarna samt som bevis på att genomförda arbetsmiljöinsatser fungerar.

Several surveys indicate that corporate leaders still consider the aligning of IT and business functions as a top management issue. The aim of this thesis is to illustrate how coordination emerges between IT and business departments and how formal structures intended to coordinate are influenced by human action. To deepen the understanding of this phenomenon we seek to analyze IT/business coordination from a perspective based on practice theory. A field study was conducted where observations and informal interviews were carried out at the IT department of a global company. The empirical analysis indicate that coordination problems between IT and business departments is in part affected by embedded factors such as different goals and perspectives on how IT is to be used in the organization or how to design IT related processes.

The high level of competition and the rapidly growing technology development has created new challenges for today's businesses where they are forced to deliver more customized products at a lower price and a shorter time period. This places high demands on the companies' ability to design and develop better products in a more efficient way. In addition to developing products, the design process focuses on securing long-term success for the company by developing nourishing skills. However, to achieve an effective design process the companies must improve their ability to plan as well as use their knowledge base in a more efficient manner. Toyota's product development system is a critical component for companies to address challenges that they?re facing and offers a great potential to create significant competitive advantages.

Every year, approximately 700 000 individuals´ visit an emergency ward in Sweden as a result of injuries and to the emergency ward at Umea University hospital (NUS) about 12 000 injured arrive every year. This study is a retrospective cross-sectional study that surveys injuries caused by crashes among 153 pedestrians and 53 bicyclists, who have been injured in a geographically well defined area during the period January to June 2009. The aim of this study is to survey injuries among pedestrians and cyclists and to examine what preventive measures could reduce these injuries in the Umeå municipality. The results show that falls caused by slipper surface are common among both pedestrians (71 %; n = 109) and bicyclists (32 %; n = 17). Almost one third of the pedestrians (34 %; n = 43) were in the age of 65 or older.

Conditions for Swedish forestry are expected to change in the future due to the climate. Among other things, increased production is expected in a warmer climate, mainly because of a longer growing season. With the changing climate risk of damage by such as insects, fungi and storms are expected to increase. Hence, it is of highest importance for private forest owners to spread these risks in the way they cultivate their forest. In this study a qualitative method was used to examine ten private forest owners with forest properties within Kronoberg county, Sweden in their attitudes and actions to prepare in terms of climate change and if they have been affected by the climate change debate in their forest decisions.

In this paper the authors aim to examine the effects on consumers using different strategies in a campaign within social marketing. A model by Evans et al (1996) has been used in order to see the different steps in which advertising catches the viewers? attention and eventually leads to action or purchasing. However, in the case of this thesis, the intention of the chosen campaign is to change the consumers? attitudes and behavior towards alcohol.

AimThe purpose with our study has been to investigate if upper secondary high schools in the south of Sweden, Stockholm and north of Sweden follow the outdoor education regulations stated in the curriculum (Lpf-94). Moreover, we aim to study if the teachers? previous experiences as well as the students affect the outdoor education. Finally, the purpose is to find out how the outdoor-life-education can be improved. These are the research questions:o How do the chosen high schools follow the outdoor education regulations stated in Lpf-94?o What obstacles, advantages and differences exist between the outdoor-life-education in these high schools?o In what way do the teachers? outdoor life experiences influence their education at school?o How can the students influence the outdoor education in their High Schools?o How can outdoor education be improved?MethodThe study is based upon data collected from four interviews with PE ( physical education) teachers from four different high schools.

The mental constructions of other places are based on impressions from everything that surrounds us in our everyday life, e.g. pictures, videos, texts and narratives. The tourism industry is especially influential when it comes to creating the image of before ?unknown places?. Furthermore, it has a tendency to embellish and idealize people and places located in what is commonly known as the Third World.

70 % of the lakes and waters in the water district of northern Baltic Sea do not reach the requirements for good ecological status. This is mostly due to eutrophication caused by a too high deliverance of nutrients from agricultural land or effluents. Losses of particulate phosphorus through water erosion contribute to a great extent to this eutrophication. In the action plan for the water district cover crops are mentioned as a measure for reducing losses of phosphorus from arable land. This paper reviews the possible effect of cover crops in the water district and discusses what crop that would be most suitable.

Preventive measurements as well as clinical caries diagnostics are vital to retain a good dental health in the population. In order for optimal caries diagnostics radiographs are used. There is a great intra- and intervariation regarding cariesprogression. A large number of tools for cariesprevention at home or in the clinic are today used. The aim of this journal study was to compare the progression of carieslesions in the approximal area, diagnosed on radiographs, and preventive measures used to reduce cariesprogression between two examine dates on two dental clinics.
