The purpose of this study is to examine senior high school students? strategies and reasoning when solving mathematical problems and make a review of the concept problem solving. The purpose is also to examine if the students? choice of strategies are influenced when their mathematical knowledge is improved.The study was conducted in two science classes at a senior high school. All the students were asked to individually solve two mathematical problems.

The PhonePages of Sweden is a company that develops software for mobile units, especially cell phones. This thesis treats the development of, and contingencies for, a mobile phone directory, using the limited resources found in a mobile unit. The project was implemented and executed at The PhonePages with the intention of creating a product to sell to a third party.By studying different solutions, their benefits and drawbacks, an abstract picture of the product was constructed. Problems covered include compatibility problems caused by todays platform diversity as well as problems with saving, organizing and presenting data.The main goal was to create a phone directory which does not make external information retrievals. The service should contain both company and personal information, with name and phonenumber.

This thesis has treated a three-axis robot which task is to serve a larger test machine tomove the modules to be tested, from the storage to the test site. The robot is composed ofthree linear actuators; two standard components of ball screw type and a custom-builtactuator of trapezoidal type. The work has mainly focused on the custom-built device to seeif it could be replaced with a standard component. Part of the work has been to look into thepicking tool and to see if there are any possibilities to improve its function.The report presents two different proposals which I decided to call Robot 1 and Robot 2 andthey aim to address the problems arising in the purpose-built linear unit and the X-axislinearity problems. Robot 1 focuses on eliminating the problems that arise around therobot's X-axis, with such simple means as possible and without making excessive materialchanges.

This bachelor´s thesis wants to look closer at librarians´ experiences of comics, manga and graphic novels. In order to bring these experiences forward qualitative interviews and the method of phenomenography was used. The material was then examend againstna theory of previous research, revealing that the problems librarians in Sweden face with these media are largely the same as the problems faced by librarians in other parts of the world. It also became clear that the participating librarians held a positive attitude to the presence of comics, manga and graphic novles in their libraries..

The aim of this quantitative study is to describe the prevalence of mental health problems within the group of children and adolescents who receive support from two in home care units within the social services of Rinkeby-Kista and Södermalm stadsdelsförvaltning in Stockholm. Another purpose is to examine whether socioeconomic background and/or gender are associated with the prevalence of poor mental health, or mental health problems of a specific kind, in the studied population. Mental health is measured with the SDQ, a behavioral screening questionnaire that is widely used in Sweden and internationally. The study is based on data collected by the two units, which routinely screen children and adolescents with the SDQ. The main results of this study indicate that mental health problems are common in the studied population.

The main goal with the master thesis has been to do a status evaluation of the chain machinery with its start chain and wire to secure the production on a short basis due to that a reconstruction is not planned at this time. An evaluation of the condition of the start chain and the rollers in the chain depository has been done. An offer has been requested for a new start chain and the evaluation of the start chains may be a basis for the decision taking. The production has been able to go on, although it has arisen some problems which have been difficult to find the causes for. There is no gathered ?picture? of the machinery status and a mapping of each machinery has been compiled of comprehensive logs.

Rabbits, Oryctolagos cuniculus, rapidly increases as pets. During the right circumstances, rabbits are friendly, social and playful. A rabbit who shows an abnormal behavior should always be examined by a veterinary, though there is almost always a medical problem. This essay is a result of a literature studie with the aim to find the prophylactic measures that may give pet rabbits a more healthy life. Rabbits have got a lot of common health problems, including dental, skin and gastrointestinal problems.

Adjustment to acquired hearing loss can be understood as a process of learning and change where the point of departure is the subjective apppraisal of a person?s hearing loss in a social and cultural context.

The main purpose of this study was to obtain insight into what students and teachers think about field trips in ecology and whether they think that fieldtrips result in increase of students? learning. Open questionnaires and half structured interviews were used to investigate this. Persons who answered the questionnaires and participated in the interviews were senior high school teachers in biology or science and high school science students. All the teachers and most of the students thought that field trips in ecology resulted in increased learning.

Nowadays in our society we find it hard for some groups of people to integrate in society. It?s known by media, that the suburbs are presented by a negative view, which often highlights the social problems in these suburbs. We can see that the suburbs still get associated with social problems such as segregation, different attitudes and behaviors, cultural conflicts, poorness etc. This kind of presentation of the suburbs affects not only the society but also the individual living and the personal perception of the individual.

Today we see a growing need and interest in working towards sustainable development. To be able to contribute to a sustainable development as individuals/business we need to emphasize the importance of education and contextualisation that learning occurs in a sense that is relevant to the learner.This is the background to this study, which in turn is the basis for an education that focuses on how to environmentally secure your purchases, an opportunity for us to set environmental standards purchasing products and services. The process for purchase is considered by many to be a key factor in businesses work towards sustainable development. Key people in this process and target audience for this education is environmental, purchasing and procurement managers.The purpose of this study is to design an education calledMiljösäkrade inköp from the target audiences? knowledge, interests and attitudes, together with literature.

In scientific investigations on how organizations can learn from their mistakes the perspective is usually that of the social engineer; the object is to prevent human errors through modeling the system in a certain way. The aim of this paper is to explore the learning process from a different standpoint than those usually applied in organizational learning and error theory. By studying the learning process in Swedish health care I seek to discover how theoretical presumptions affect the outcome in terms of what we actually learn. The theoretical framework draws on two major discussions in contemporary political science; the question of structure and agency and the question of whether to focus on formal or informal structures when explaining organizational behavior.The investigation shows that Swedish health care tend to understand human errors as a result of formal organizational structure. Such a view leads to insufficient explanations to why errors occur but is useful in producing preventative measures.
