Cannibalism can have major influence on fish population dynamics. A prerequisite for cannibalism is that the cannibal and the potential victim meet, and besides density effects, the encounter rate between cannibals and their victims is therefore also largely dependent on habitat use and habitat heterogeneity. In this study I quantified and compared the potential for cannibalism in stream-dwelling European grayling populations in three rivers in Jämtland by means of habitat classifications. I also analyzed population dynamic consequences of varying the potential for cannibalism in terms of intensity, using a physiological structured population model. Findings based on habitat characteristics were that the potential for cannibalism is in general not favourable in these types of streams.

AbstractSeveral of researchers have reflected that the school ought to be developed to a learning organization. A method as proceed from such a perspective and should be able to match a local child- and educations administration is problembased school development. To investigate in which ways a child- and educations administration prosecute a problem based learning inside the organization a case study was used as research strategy. The question this report gives answer to is:In what/which way works a child- and educations administration in a rural district with a method to fulfil a problembased learning.To collect empiric data a canvassing inquiry was accomplished among the child- and educations administrations group of management. According to the research result it can declares that there are good conditions for the organization to prosecute problem based school development, but there is yet a great deal to do before it´s can be said totally fulfilled.

The Squares Family is a game developed as a learning aid in mathematics. With its graphical representation of the decimal system, the four basic arithmetic operations and positive and negative numbers together with a learning agent as pedagogical approach, the game?s primary purpose is to motivate students in their learning of mathematics. Although the game is strictly based on mathematical rules it attempts to encourage students to play and work with math without experiencing it as mathematics as this is initially not obvious. The game being internationally tested on normal performing students, this project introduced the game to six Swedish students who experience low motivation for and/or difficulties in mathematics.

In view of the difficulty of recruiting staff to care profession and in terms of the increasing need to find ways of ensuring a good language level in the profession, have an interest in language tests been revealed.

 The purpose with this thesis was to develop a designguideline which will simplify the development of new products that will be laser welded. The need for this thesis has come forward from the quality problems that Volvo Construction Equipment, Components Division is having with their laser welding manufacturing unit. The reason for the problems emerges from the bad communication between the development unit and the manufacturing unit within the company when the products produced today was developed. This resulted in products that were hard to and in some cases almost impossible to weld. To avoid these problems from occurring again it was needed to gather the experiences within this area and compile it and present in a brief a pedagogical manner. The information for the groundwork of our results has been gathered by interviews of several key persons in Volvo Construction Equipment, Components Division.

Avsikten med min undersökning var att få mer kunskap om hur förskolepersonal arbetar med pedagogisk dokumentation som ett arbetsverktyg i deras dagliga verksamhet. Det är ett arbetsverktyg som ska tillämpas av all förskolepersonal ute i verksamheten.För att ta reda på vilka erfarenheter förskolepersonal har av pedagogisk dokumentation var en kvalitativ intervjumetod det bästa sättet eftersom informanterna genom en kvalitativ metod får svara på frågorna utifrån deras egna erfarenheter. Jag vill också ta reda på hur de gör för att synliggöra varje barns behov.Jag har hänvisat till och använt relevanta tidigare undersökningar för att analysera resultaten från min studie.Resultaten visar att pedagogisk dokumentation är ett arbetsverktyg som ska användas för att synliggöra verksamheten och barnens lärprocesser. Lärprocesser sker när barnen utmanas i deras lärande, där nya idéer och kunskaper växer fram. På så sätt finns det möjlighet att strukturera verksamheten utifrån barnens olika behov och intressen menar mina informanter.

The public sector is a major purchaser of goods and services. By setting requirements for environmental and social considerations in public procurement, an authority has the possibility to use consumer power to influence the actors in a market. The purpose of this paper is to investigate public procurement of textile products in a municipality, in order to gain knowledge about factors that may be important for the use of environmental and social criteria. Håkan Hydén´s (professor in sociology of law) norm model was used as the basis of the analysis, where the conduct was investigated along three dimensions of the norm ? willingness, knowledge and system conditions ? in order to identify underlying factors that can influence the process.The results ? analyzed by using interviews and documents ? show that the procurer's willingness, motivation and knowledge are important factors in this context, as well as the political priority of the municipality.

Reading and analyzing literature has a long tradition of being an essential part of the teaching of English in Sweden. As the offers of entertainment have increased in popular culture with the introduction of computer games, internet and other media, interest in reading novels has decreased. Literature is still a compulsory part of English teaching and the question is how teachers of today use literature and what kind of literary instruction they use.The aim of this study is to explore and discuss the literary instruction discourse in pedagogical texts, lessons, created by and for English teachers of Swedish Upper Secondary Schools. The lessons have been collected from the site lektion.se, where teachers are able to share knowledge and lessons. The study uses an analytical method based on Norman Fairclough´s Critical Discourse Analysis in order to analyze the lessons.

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.

Sammanfattning Utgångspunkten i den här studien har varit lärarens muntliga kommunikation och hur den kommer till uttryck i den konkreta undervisningssituationen med fokus på skolämnet idrott och hälsa. Pedagogisk forskning om lärande och ämnesdidaktisk forskning brister ofta i att hänsyn ej tas till lärarens roll och dennes muntliga kommunikation i undervisningen. Området är relativt outforskat vilket är förvånande då lärarens främsta redskap är hennes tal. Syftet med den här studien var att ge en bättre förståelse för hur lärares muntliga kommunikation kommer till uttryck och om ämnets karaktär är av betydelse. För att ta reda på detta har jag använt mig av en kvalitativ forskningsansats med intervjuer och observationer som undersökningsmetod.

The intention with this study is to investigate how schools are affected by state and municipal documents when they organize the education for children with special needs. The study is based on following questions.How do decisions on state and municipal level of politics affect the decisions that the principals make concerning organization, and do the school leaders think that the decisions are made on the right level of liability?What is the relationship between economic decisions and pedagogical decisions?What decides whether the schools have children with special needs integrated in their ordinary classes, or if they receive segregated remedial courses, and what are the views on an equivalent education?The study is conducted through interviews with principals of three schools, one politician on municipal level and one special education teacher. The interviews are linked to an historic background as well as current studies and discourses. The study shows that there are contradictions between state, municipality and school goals.
