Environmental variables determining the occurrence of the red-listed Carbonicola anthracophila and C. myrmecina in boreal forests

The global biodiversity loss is mainly due to human activities such as an intensification of forestry. Boreal forest ecosystems in Fennoscandia are characterized by disturbances such as forest fires, storms and floods. However, industrial forestry practices suppress forest fires and change the landscape, leading to a loss of habitats and associated species. Particularly lichen species with slow adaptation abilities and a strong substrate specificity face an extinction debt in boreal forests since their substrates are long-lived but no longer created. In this study the species-substrate relationship of two red-listed forest-fire dependent lichen species Carbon-icola anthracophila and C.

Föryngring och produktion av skog på torvmark

Kunskapen kring svensk torvmarksbeskogning är undermålig. En kunskapslucka som till stor del beror på att torvmark tidigare bedömts som ointressant mark i samband med skogsproduktion. Detta beror mycket på det svenska regelverkets restriktioner mot markavvattning och gödsling samt miljöaspekterna som berörs och den aktivare skötsel som krävs. Det ökade behovet av skogsråvara gör att skogsbruket söker nya marker där torvmarken har potential att etableras för skogsproduktion.Studien är en kunskapssammanställning som lyfter fram kunskap kring skogsbruk på svensk torvmark med fokus på föryngringsprocessen. Finland använder torvmarker i skogsbruket på ett sofistikerat sätt.

Varje ord är viktigt! En kvalitativ studie av socialsekreterares syn på utsatta barn.

The purpose is to examine social workers view of vulnerable children and their needs. We are also interested to know how social workers think and discuss concerning the help these children are given. Our main questions in our study are; How do social workers define vulnerable children? Which needs do vulnerable children have according to social workers? Which opportunities and difficulties might there be in the decision making when trying to help these children? Which public authorities do social workers cooperate with? Which opportunities and difficulties do social workers find in the cooperation?This study is based upon interviews with ten social workers in the social childcare division in different municipalities in Skåne region, Sweden. Our results are explained and analyzed with a qualitative approach through different aspects of power- and Human Service Organization theories.

Mobbning i skolan : En studie om omfattningen av mobbning riktad mot funktionshindrade och orsaken till detta

Bullying in schools is a big social problem in today?s society and it affects the children exposed in a very negative way. The aim of my paper is to find out if there is a group of students who gets bullied by other students more often than others. I want to study if children with functional disabilities get more bullied than children without functional disabilities and,if this is the case ? why is it so?My questions are:Are children with functional disabilities particularly exposed to bullying?How is bullying prevented?In order to get my results I have made three qualitative interviews and analyzed two debate articles concerning bullying of the disabled.

?dn?ris?: att b?ja st?nger till t?ltk?ta

This thesis is my exploration of the immaterial heritage that is the craft of bending of ?dn?ris? out of spruce. It?s a broken tradition that is scarcely described, mainly through Yngve Ryd?s report T?ltk?tor (1999) that contains interviews with two knowledge keepers, Nilas Tuolja and Johan Rassa. Yngve Ryd?s report went against the earlier opinion by the mid 20th century ethnologist Ernst Manker who claimed that they were only made exclusively out of mountain birch that has curved growth. As a background, I discuss the special importance of heritage conservation, both material and immaterial, in a S?mi context as being an indigenous people.

Mellan tvång & frivillighet : Förebyggande insatser i LVU

The purpose of this paper is to determine the established law and make researches into non-institutional compulsory care (?mellantvång?) paragraph 22 The Care of Young Persons (Special Provisions) Act (from now on called LVU) and examine whether the administration of the law is in harmony with the best interests of the child.This paper combines two methods : traditional judicial method and a social science method. In the juridical part the sources of law have been studied and in the social sciences part semi-structured interviews have been conducted with five respondents. The theoretical framework consists of ideas and theories about the best interests of the child, a concept which is one of the UN Convention on the Rights of the Child's core principles.This study shows that the legislator has identified a problem and an existing need and found a solution to this by introducing a non-institutional compulsory care, paragraph 22 LVU. The problem is that Social Services do not make use of the restraint.

Samgång av olika arter på svenska djurparker

Zoos currently aim at keeping animals in as natural habitats as possible, since they havegone from displaying exotic animals to working with conservation of endangered species.It is therefore more common that zoos keep groups composed of two or more species in thesame enclosure. The aim of this report is to study why and how different species are held atzoos. Species in the wild can interact in different degrees depending on season andresources. When species are held together at zoos the space can be more effectively used,the animals increase their activity and the visitors increase their learning. Mixed speciesenclosures involve more work and risks of injury.

DISA - En bra metod för tonårspojkar?

The DISA method is a universal program developed for teenage girls to prevent depression. The program includes cognitive behavioral techniques are suppose to change negative pattern of thinking, give practice of communication, strategies of problem solution and exercises to strengthen the social network. The purpose of this study is to find out how a group of teenage boys were affected by the DISA program and what factors that may have impacted the outcome. Material from three different studies have been used, a quantitative study in terms of data from self-assessment form CES-D, materials from two semi-structured focus group interviews with the boys and material from a questionnaire filled out by the boys on two occasions during the DISA method. The result of the CES-D indicates that the boys had less depressive symptoms after the final group meeting compared to the first group meeting and also a year later. Analysis of the material from focus group interviews and questionnaire have been made from a communication theory and systems theory perspective and indicate a shift to greater cohesion in the group and demonstrates that communication between the boy-group and group leaders had importance for the outcome.

Introduction: During the last decades, the development of the communication society has contributed to new patterns of communications among people, but also increased the use of computers and mobile devices. It has become more common to communicate through social medias, which has led to the new phenomena cyberbullying. At the same time, studies have shown an increase in mental health problems among adolescents during the last 25 years. Aim: The aim of this literature review was to investigate and map the characteristics of cyberbullying and its relationship to mental health among adolescents. The aim was also to investigate adolescents own actions to stop cyberbullying.

?Båtnitar? : Analys och konservering av järnnitar från Birkas garnison

The purpose of this paper is to analyse and discuss clinch-nails found at an excavation at terrace II in the Garrison of Birka, on the island of Björkö in Sweden. This type of clinch-nails is common in Viking age Sweden and is usually interpreted as coming from boats. The study will try to show that these types of nails could have been used in several kinds of wooden constructions. It will also show how the nails were made and what kinds of tools were used by the Viking smiths. The study has shown that this type of nails were used in several different types of wooden constructions such as boats, sleds, cart bodies, coffins, Birka's ramparts and buildings.

Åtgärder för biologisk mångfald i parker : Fallstudier i Botkyrka, Haninge och Nynäshamn

Biodiversity consists of all life on Earth and in all forms. Biodiversity is often discussed at three levels: ecosystem, species and genetic variation within species. Biodiversity also provides many of the ecosystem services performed by nature and that we depend on, including cultural services such as aesthetic values, education and recreation. In Sweden the environmental objectives are central; there are 16 environmental quality objectives, and "A rich plant and animal life" is one of them. Conservation and sustainable use of biological diversity is a prerequisite for achieving also most other environmental objectives. Another environmental quality objective that is tied to a rich biodiversity in cities and biodiversity is "Good built environment" where cities, towns and other built environment should provide a good living habitat and contribute to a good environment.

  Opioid-inducerad obstipation i samband med postoperativ smärtbehandling : Förekomst och förebyggande åtgärder

Objective: The objective was to examine the incidence of constipation, and the preventive measures taken in relation with postoperative pain treatment with opioids at two orthopaedic surgery wards.Methods: The participants were patients that had undergone surgery in the back, hip or thigh. They were selected through systematic selection and a total of 46 electronic health records were examined. The factors investigated and tested for correlation with constipation were the usage of laxatives, daily fluid-intake and early mobilisation.Results: Totally, 26.1 % of the patients became constipated, and laxatives were prescribed to 65.2 % of the patients. Doctors prescribed 53.3 % of the laxatives, nurses 33.3 % and for the remaining 13.3 % it was uncertain who had written the prescription. Usage of laxatives seemed to cause constipation (p=0,025), whereas there was no correlation between constipation and early mobilization.

Det svenska områdesskyddet : Ett samspel mellan diskurs och institutioner

Sweden has had laws protecting nature for about a hundred years. In this paper the views of nature and the values that serve as a rationale for protective measures are analyzed as results of a social process characterized by the dialectic relationship between institutions and discourse. Critical discourse analysis (CDA) is used to study this relationship and the discursive practices used by institutions, which reproduce or reshape views of nature that define the relationship between society and nature. Institutional design contributes to shaping discourse in the field of nature protection, while being originally shaped by discourse. In Sweden, the national park is an institution that reproduces a view of nature as the wild and untamed opposite of society, and the natural reserves reproduce a view of nature as holder of a multi-faceted set of values intertwined with society.

Förvildade husdjur : möjligheter och hot

Feral animal populations are distributed over many parts of the world and are often seen as a problem. Since they are a threat against other species, destroy farmlands and can spread dis-eases, they are often referred to as pests. Artificial selection has contributed to loss of genetic diversity in our domesticated animals. Feral animal populations are affected by natural selec-tion, which allows them to adapt to the environment. Their ability to adapt is a reason to see them as pests but can also be seen as an asset.
