When investigating mechanical problems it is often more convenient to deal with scalars rather than vectors. In this project methods stemming from the field of analytical mechanics, which lets one derive the equations of motion using scalar quantities instead of vectors, have been used. Two mechanical problems were investigated, a double pendulum with a spring and particles orbit in a sphere. The equations of motion of the two systems were derived with the assistance of computer algebra, using Maple and the external package Sophia. The systems were investigated with regard to periodicity and conserved quantities..

The aim of this study was to understand the contact between foster homes and social workers, by doing a comparison of the social workers and the foster homes experiences of the cooperation that is between them. We started from three main questions to get an answer to our aim, how the foster homes and the social workers experience the organization of the foster care in the Social Service as an impact of the cooperation, what does the foster homes and the social workers experience as a important fact of a successful placement and finally, how does the foster homes and the social workers experience the supporting and controlling contact that is between them. To get our results we based our study on interviews whit four foster homes and whit four social workers. The analysis was based on one theoretical perspective, Skaus (2007) analytical approach for power and help. As a conclusion we have found out, that the organization of the Social Service has significance for the contact between social workers and foster homes.

The purpose of this essay was to look into whether any attention is paid to the biological children in foster families when the investigation about foster home is made. I did some qualitative interviews with six foster home-investigators, working in five different municipalities. Some of the main questions have been: Do the investigator meet the biological children during an investigation? Are the children´s opinions taken into consideration? Is the suitability of a foster home judged even from the biological children´s perspective?It was shown that it could happen that a foster home was not approved, if it for some reasons should be a negative experience for the biological children, if a foster child would be placed in their home. All the six persons in my interviews thought that it is important to take the biological children´s opinions into consideration, and that the family is not suitable to be a foster home if not all of the family members have a positive attitude.

The study aims to gain insight into how social workers perceive their psychosocial work environment and examine whether this effects the performance of their duties. The study mainly addresses the shortcomings of the psychosocial work environment of Social Services and the implications it entails for social workers health and wellbeing. The psychosocial work environment includes physical and psychological factors therefore the study's interpretive framework consists of organizational theoretical and social psychological concepts and previous research on the subject. We examined the organizational and social psychological connections to social workers perception of their work environment with a qualitative approach. The empirical data was collected through interviews with four social workers in a municipality in central Sweden using a semi-structured interview guide.

Ten years ago the public computers with Internet access were introduced in the public libraries. The purpose of the public computers was to give the possibility of searching information. Along with the Internet came also communication media like chat and e-mail. This type of communication was a new function for the libraries and the reactions among the librarians were mixed. It has been a source of big frustration and attempts to block it has not succeeded.

The purpose with this essay is to explore the importance of Corporate Social Responsibility (CSR) within the food industry. We have decided to focus on how five different ethical labels are communicated towards students and the standpoint of the study is the students understanding of the communication. The labels that we have chosen to examine in the study are KRAV, Fairtrade, Svanen, Ekologiskt Jordbruk and Rainforest Alliance. The primary research question in the study is? How are the students purchase behavior affected by ethical labels in the food industry??.Throughout the study we will refer to CSR-products as products are stamped with one or several of the named ethical labels.

Prioritisation of software requirements is a critical part of the development of software. Whichrequirements and in which order they will be developed is one of the main tasks that requirementprioritisation supports.There are different ways that a requirement prioritisation can be used, for example alone or in agroup and with different methods.The purpose of this report is to map out how you can carry out a requirement prioritisation alonewith different types of prioritisation methods and how you solve the problems that can arise whenprioritisting requirements. This is done by documenting the use of three different types of methodsthat can be execute alone. The methods are "100-dollar test", "Ranking" and "Top-tenrequirements".To be able to prioritise requirements, you need to establish which requirements you shall prioritise.The paper retrieves this information by interviewing stakeholders in the system and analysing theresult of the interviews and the execution of the requirement prioritisation.Three problems arose during that work and I present solutions on these problems. The problemswere 1) equivalent requirements when using the "100-dollar test", 2) low differentiation gradebetween the prioritised requirements in the "100-dollar test" and 3) that the requirements that wereprioritised weren't classified before the prioritisation, which leads to inaccuracies in the resultingprioritisation.The solution to the problems that the paper presents is to increase the amount of distributable unitsin the "100-dollar test" to 1000 per requirement, suggestions of classes of the requirements andthe combination of the methods "100-dollar test" and "ranking" to bypass the equivalentrequirements.The report is written in Swedish.Nyckelord: GoTRIS, requirements retrieval, requirements analysis, Viktoria Swedish ICT,requirements prioritisation, requirements, 100-dollar test, ranking, top 10 requirements..

The purpose of doing this research except for educational reasons is to show significant effects that make motivational work successful. The choice of subject we decided out of experience from the term of practise. The description of the subject is from the social workers angle of approach. The method we used is a qualitative study with semi structured interviews. We have looked at three different fields of social work from the view of six social workers, two from each field.

The aim of this study was to understand how social workers perceive and understand violence and threats of violence from clients, and how it effect their working environment. It seems that the respondents understand the violence and threats of violence from clients as a result of the clients background problems, vulnerability, dependency and from ?the reason" that the client is currently in the contact with the organization. How respondents interpret the client´s behaviour based on the above-mentioned factors, seem to determine how the respondents perceive and define the violence and threats of violence by clients directed against them. Interestingly enough, although all respondents in the study experienced violence and threats of violence from clients, none of them perceived themselves as exposed at work. The answer to this is consensual.

The Swedish sports retail industry has experienced extensive growth during the last decade, and this has attracted new entrants to the market, both start-ups and international followers. This has inevitably put more pressure on incumbents, which are now confronted with major challenges as how to retain their customers and market shares. Customer loyalty has been proved to be an important factor for customer retention and proposed to constitute inertia of switching behavior. In light of this problematization, the purpose of this study is to describe the underlying factors of loyalty and whether purchase habits could further explain customer loyalty. The aim is also to understand the strategic implications of the factors involved.

The purpose of this essay was to examine how youths are described in certain written statements that are produced by the social services. The statements that this study has focused on, are those written with the purpose of serving the court with suggestions of treatment-measures when a person between 15 and 18 is suspected of having committed a crime. The main issues were: How is the content in these statements described and what do these descriptions tell the reader? Do the images of youths in the statements differ, depending on the degree of intervention for the suggested treatment-measure? The essay is based on a qualitative content-analysis of 50 statements and the material has been analysed from a social-constructive theoretical perspective.The study shows that the youths in the statements are described through descriptions that reinforces a positive or a negative image of the youth, and that these descriptions are described as either utterances or facts. Depending on the degree of intervention for the suggested treatment-measures, the information in the statements differ in that descriptions that are likely to reinforce a positive image of the youth are more frequent in the statements where no or less intervening treatment-measures is suggested.

Today the most commonly material used in the body is galvanized steel sheets and by shifting material to Hybrix several problematic issues have to be dealt with. Hybrix is an innovative sandwich sheet that inherits thin stainless steel face sheets and a stainless steel fibrous core.

Bolivia is a multiethnic country where the indigenous people constitute the majority of the population. Despite two decades of attempts to take the democracy further is its foundation more volatile than ever. The aim of this bachelor thesis is to examine if exclusion is taken place in Bolivia from year 1982 until today and if so in which way political exclusion constitute problems of democracy in Bolivia. The answer depends on the understanding of democracy used in the analysis. In this thesis I use theories of process-, participation- and deliberative democracy.

Research about social support and social networks has mostly concerned the impact on a person?s wellbeing and health. However an aspect largely neglected is how social support within the social networks can affect the process of giving up a drug abuse. The purpose of this paper is to contribute to a better understanding of what role the social support within different relationships can have on the process of giving up drug abuse. Furthermore the aim is to examine how a self-help group can provide social support in the transitional period after leaving a drug abuse.
