Den anonyma handeln på värdepappersmarknaden : några juridiska aspekter
Trading financial securities at stock exchanges and other authorized market places is today a particularly important socioeconomic phenomenon in many industrialized countries. A well functioning securities market is crucial for the economic development in these countries. The modern trading with stocks and other financial securities is characterized by the fact that the majority of the transactions at the stock exchanges are carried out through various intermediaries. The ultimate counterparties that are involved in a securities transaction (the seller and the buyer) are often unknown to each other. The anonymity in the securities trading implies several interesting legal problems.
Elevers lärande i grupparbeten : en kvalitativ studie av en grupp elevers tankar kring lärande i grupparbeten
The purpose of this study is to investigate how a group of students experience their learning when working in groups, and determine if they prefer to work individually or in groups. This study will also investigate what the students believe that they learn when working in groups. The study is based on these two questions:How and what do students perceive that they learn from working in groups?Do the students in my study prefer to work in groups or individually?The method I have used to retrieve information has been to interview four different students. The interviews were individual; I did so to get a deeper view of how students perceive their own learning in groups.
Att lära sig dansen i arbetsalliansen : En kvalitativ skildring av en personalgrupps sociala interaktioner inom en stödverksamhet
Det är viktigt att personalgrupper inom behandlings- och stödverksamheter präglas av positiva sociala interaktioner och lyckade ritualer för att uppfylla funktionalitet och effektivitet. Brist på positiva sociala interaktioner och lyckade ritualer riskerar att skapa en personalgrupp som präglas av oenighet och konflikter. Studien syftar således till att undersöka hur sociala interaktioner i en personalgrupp inom en stödverksamhet inverkar på det dagliga arbetet. Studien syftar även till att undersöka hur en positiv och funktionell personalgrupp skapas genom samspel mellan gruppmedlemmarna. Vidare diskuteras relationen mellan personalgruppens funktion och klienterna.
Motivation ur ett elevperspektiv : En studie om vilka faktorer som har betydelse för elevers motivation
AbstractThis study deals with motivation as an overall concept, from a student perspective. It encompasses factors that could directly affect students and their positive or negative motivation, concepts such as relationships, communication, expectations and interactions and their importance to my informants.The study also discusses certain theories to show the different ways of defining motivation, specifically in relation to my informants and their and my conclusions. My ambition is to establish the importance of the concepts mentioned above, as well as perspective changes to the enhancement of the performance standards of a good teacher.The purpose of this work is to describe, understand and clarify the external and internal factors that affect motivation. In order to achieve this purpose, I chose to use a method of qualitative interviews with three students, with different backgrounds, schools and conditions but with a lack of motivation as a unifying characteristic. The research questions were as follows:What factors influence students' motivation? What impact do achievement targets have in relation to the pupils? own motivation to learn?How important are teachers' expectations for the individual student's motivation?Within this study sub-concepts such as importance of expectations, relationships, and significant others are, according to my analysis, of great importance.
Timmerkvalitet hos björk i blandskog med gran
Birch is the dominant deciduous tree species in Sweden but only 16 % is found in pure birch stands. The majority of the birch (51 %) is to be found in conifer dominated stands. Swedish forest land comprises approximately of 23 % mixed stands and one problem is that for mixed stands there are few management recommendations. The underlying aim of this thesis was to study the management of mixed forest stands of spruce and birch to achieve good timber quality of birch. The study was based on a literature study and measurement in a field experiment launched in 1998 by the Swedish University of Agricultural Sciences (SLU).
Undervisning i naturkunskap, demokratiuppdraget och interkulturell pedagogik : Kan en interkulturell pedagogik öka intresset och motivationen för ämnet naturkunskap bland elever på samhällsprogrammet?
Since studies points out declining interest in science among students in Swedish schools, I have in this paper chosen to examine how some students at the Social Science Programme are experiencing the lessons in Natural Science and how to make lessons more interesting according to these students.The purpose of this study was to gain a greater understanding of how teachers would develop new perspectives and tools to make lessons in Natural Science more interesting. I also wanted to investigate whether an intercultural perspective could be a possible tool to increase students? interest and motivation.As a theoretical framework, I have assumed Vygotskij's sociocultural perspective, Habermas's theory of deliberative conversations and an intercultural perspective. Through a qualitative approach, I conducted interviews with students and teachers. The main results showed that students felt that natural Science lessons were too theoretical and undemocratic and that they wanted to have more student interactions, such as discussions and group works.

This makes the study aim regards investigating which non-verbal signals a real estate agent express.Purpose: This study has a two-parted purpose whereas the first part intends to point out similarities and differences in a realtor?s non-verbal communication.
Feline Odontoclastic Resorptive Lesion (FORL) : en morfologisk beskrivning
Feline Odontoclastic Resorptive Lesions (FORL) is a painful disease that affects feline teeth and that is increasing in prevalence. The ethiology is still rather unknown. However, research on the ultra structure of the feline tooth may help us understand why FORL is so prevalent in cats and not in other species. Since the ethiology is still unknown, there is yet no profylaxis. The pathogenesis is rather well known; the hard structure of affected teeth gradually undergo odontoclastic resorption and resorptive lesions are often partly replaced with bone- or cementum-like tissue.
Lättlösliga kolhydrater i vallfoder och i hästens grovtarm :
The purpose of this study was to investigate how the content of glucose, fructose, sucrose and fructan (WSC) varied in silage, haylage and hay harvested from the same field and at the same time of harvest. The study also investigated if differences in the WSC-fraction in the forages caused differences in composition of WSC in the colon of horses fed the forages. Hay, haylage and silage were harvested in the first week of June 2005 and stored for about nine months before feeding. Horses that were fistulated in right ventral colon and caecum were used, but only the colon fistula was used for sampling.
The fresh crop and the conserved hay, haylage and silage were analyzed for chemical composition and WSC-fraction.
Cultivation of Chlorella vulgaris in nutrient solution from greenhouse tomato production : a possibility to reduce nutrient levels and produce commercially interesting metabolites
The idea of using algae in different areas and exploring its possibilities is nothing new. Already in the early 1950s microalgae was explored as a possible food resource because of its high protein content. Lately there has been an increased interest in its potential for industrial use. Wastewater treatment is a possible use of algae since the algae grow well on the nutrients present in the water. This offers the possibility to grow algae for nutrient reduction and use the biomass for energy or animal feed since many alga species has a good nutritional value.
Approximately 800-1000 m3 water is applied per 1000 m2 of greenhouse area during one season in a tomato production.
Vegetationsutveckling och mänsklig aktivitet under äldre Stenålder vid Döudden, Arjeplog kommun :
The landscape in the interior of Norrland has undergone dramatic changes since the deglaciation as a consequence of faultings, earthquakes and tilting of the landscape westwards. Archaeological investigations along former shorelines by the use of models of isostatic land uplift, have revealed many Mesolitic settlements in northern Sweden. Döudden, in the county of Arjeplog, has been investigated by archaeologists that identified settlements from 5200 BC. The objective of this study was to analyse the history of the vegetation and if the vegetation showed traces of human activity during early Holocene, by pollen analysis. The results indicate that the area had an established vegetation c.
Näsnarens framtid i ett näringsstatusperspektiv
Eutrophication has been a problem in aquatic systems for a long time. It is well known that the key nutrient to control the eutrophication process is phosphorus. Lately, it has been possible to reverse the process and recover lakes from eutrophication.During a long time Lake Näsnaren in Katrineholms kommun, Södermanland, has been exposed of a large amount of phosphorus from the city's wastewater. The lake has a great value as a habitat of rare species but also a high recreation value for people living in Katrineholm and Södermanland. Lake Näsnaren is situated in a Natura 2000 area.
Kommunikativa samspel mellan barn och pedagoger : Vad utmärker en fungerande tambursituation?
AbstractThis text deals with one of the preschool everyday routine chores, and the phenomenon I have chosen to investigate is the hallway situation. The purpose of the study was to see if the hallway situation offers good communicative interactions between children and teachers, and investigate if the teachers use special strategies to make the hallway situation work. The method of this study was survey, qualitative interviews and observations. The three methods have deliberately been selected to best suite and reply to the different issues.Today?s groups of children in preschool are very big, and some of the preschools are not adapted to these large groups of children that we have today.
