Verksamhetsstyrning i grundskolan - En väg till goda förutsättningar för inlärning

This study investigates how performance management in primary schools can facilitate learning, relating to theories of efficient schools. This is done through a qualitative study of the performance management systems in two public primary schools in Sweden. The schools selected were similar in all major aspects, except pupil grades, where there was a clear difference between the schools. The analysis revealed differences in how the schools handled the process of management by objectives, the professional development of teachers as well as routines, rules, and policies. We conclude that having a rooted process for management by objectives, professional development of teachers, and clearly formalized values, gives a school a good foundation to support a pupil's learning and development..

Hur tänker barn att de ser ut inuti? : Vad har 3- och 4-åringar för uppfattning om insidan av kroppen?

AbstractMy purpose of this essay was to discover three- and four-year-olds comprehension of their internal body and then compare the result between their ages. I have used the same methods in both essays, semi-qualitative interviews. It is structured interviews with space for following questions. My formulations of the questions were: Do the children have a comprehension of their internal structure of the body? Do the children have a comprehension of organs and organ systems? Is there any difference between the ages?Their comprehensions I have categorized in four categories and I have seen age related differences in their comprehensions.

Samband mellan ungdomars föräldra- och kompisrelationer

During adolescence the teenager tries to become an independent individual, something that for many individuals can be experienced as"a hard time". In early childhood the individual was closely connected to the parents, but during adolescence friends and new contacts become more important. Studies in developmental psychology have most often adopted a parent-perspective, which is why a child-perspective is required. The aim of this study is therefore to measure the teenager's relationship with parents and friends and to look for possible correlations between these. As a means of measuring quality in the relationships, the IPPA, the Inventory of Parent and Peer Attachment, was used.

Background: Sweden?s membership in the EU affected the Swedish accounting regulation. Three EU-directives was implemented in the Swedish accounting regulation.

"Att tända gnistan och få den att flamma upp" : Samverkan mellan lärare och skolbibliotekarier på låg-och mellanstadiet

The aim of this bachelor thesis is to examine the collaboration between school librarians and teachers in primary school, in order to illustrate how the two professions can work together, how they see their own roles and how they look at the other professionals´ roles. We also discuss earlier studies in LIS concerning collaboration between teachers and librarians. The method of investigation is qualitative interviews with practicing school librarians and teachers, we interviewed three school librarians and three teachers from three different schools in the same county.  As a basis of the discussion and analysis Andrew Abbott's theory of professions is used. The thesis shows that collaboration differs between the schools.

Euron, mer än siffror på ett papper? En studie av Eurokrisens påverkan på relationen mellan europeisk identitet och inställningen till euron

This bachelor thesis aim to explore in what way the Euro crisis have affected the reciprocal relationship between European identity and the attitudes towards the euro, and how it differs between the members in the Eurozone and members that have not yet introduced the euro. This thesis is grounded in a theoretical view that the euro is a symbol through which European identity is created, but also that European identity is a factor for the attitudes towards the euro as a single currency. By statistical analysis of empirical data collected through the Eurobarometer, I discover that there is a difference between how the relationship between the European identity and the attitudes towards the euro changes during the Euro crisis. Members without the euro seems to be more affected than members with the euro, as the correlation between European identity and attitudes towards the euro weakens for members without the euro, which do not seem to be the case in member countries within the Eurozone..

Folkbibliotekarie på lika villkor? en intervjuundersökning om folkbibliotekariers kvalifikationer och vad kvalifikationerna betyder för folkbibliotekarierna och folkbibliotekets verksamhet.

We studied the understanding of public librarians of the required qualifications for a public librarian, what these qualifications embody and how they should be used, and if there are any differences between geographic regions. We also compared our results to the Library Code, which describes the responsibilities of the public libraries. To complete our study, we interviewed fourteen public librarians at eight different public libraries located in both urban and rural areas in Sweden. Our results showed that even though the qualifications specified by the Library Code were identical, they were emphasized and used differently by the public libraries included in our study. This illustrates that the public libraries prioritize and focus differently on the various aspects of the Library Code.

Friheten från fattigdom - En rättighet eller något annat?

This paper investigates whether there is a right not to suffer from poverty. The investigation is being conducted from the theoretical standpoint/view that only civil and political rights constitute justiciable rights and rights proper from a moral stance, whereas economic and social rights constitute mere political agendas or less.In the search of an answer to this question the content of economic and social rights, and thereafter civil and political rights will be outlined, followed by an inquiry of what should really be considered as rights. Finally, the arguments against economic and social rights as real rights is presented and scrutinized.This paper will conclude that the stated difference between the above-mentioned sets of rights is illusory and that the right not to suffer from poverty ought to have the same status as civil and political rights..
