Anlockning och gnag av snytbaggar (Hylobius sp.) : effekt av plantstorlek och behandling med metyljasmonat

Two field experiments were conducted in central Sweden in order to: 1) Determine a relationship between the number of approaching pine weevils (Hylobius sp.) and the number of attacks by pine weevils, in relation to the size of seedlings of Scots pine (Pinus sylvestris). 2) Determine if application of methyljasmonate (MJ) on seedlings of Scots pine will result in higher resistance towards attacks by pine weevils and/or have any effect on the number of approaching pine weevils. The field experiments were designed with two separate parts in close vicinity on the same clear cuttings: a) pitfall traps placed in patches of scarified soil that caught approaching pine weevils at 2.5 cm from the bait, which consisted of different sized seedlings of Scots pine some of which were subjected to application of MJ and b) the same type of seedlings planted out in patches of scarified soil. The first field experiment was conducted on a 1-year old clear cutting outside Uppsala in east central Sweden and the trapping part of the experiment consisted of 8 blocks with 6 treatments: 1) control, 2) small over-wintered seedling, 3) medium sized seedling, 4) medium sized seedling treated with 0.5 ml 100 mmol MJ 4 days prior to start of experiment, 5) large seedling, 6) vial with 9.5 ml of ?-pinene. The trapping experiment lasted for 6 weeks in the early summer.

Vad räknas som mjuk balansering? Om Venezuelas ambitioner att minska amerikanskt inflytande

This thesis deals with the concept of soft balancing, traditionally defined as the diplomatic means of restraining a dominant state's ability to exercise its military power. As the dominant power in today's unipolar system, the United States, and other states? behaviour towards it, is the focus of analysis. The aim of this thesis is to explore the possibilities of developing the concept of soft balancing so as to include strategies to restrain also the political and economic capabilities of a dominant power. The thesis also considers the possibilities of soft balancing that small states ? to a large extent overlooked in existing theories on the subject - can possess.As a state with policies that aim to reduce the U.S.

Structure and tree diversity of lowland limestone forest on Seram Island, Indonesia

There have previously been very few studies of forests on Seram Island in the Eastern Indonesian archipelago and none before on lowland limestone primary forests. The COLUPSIA project on collaborative land use planning has therefore chosen Seram as one of two project sites. The objective of the COLUPSIA project is to establish collaborative and equitable land use planning. In order to achieve its objective the COLUPSIA project aims to improve understanding of traditional resource management and how it interacts with governmental systems, as well as enhancing knowledge about tropical landscapes and ecosystem services.The aim of this study was to contribute to the COLUPSIA project through describing lowland limestone forest on Seram Island in respect to (1) forest structure, (2) tree species richness and (3) tree species composition. We set up 5 plots, each of 0.2 ha, at one site, Mawalai, and collected data on tree variables (tree diameter ?10 cm) as well as for some other life forms and environmental data.

LAURA: Kognitiv beteendeterapi för kvinnor med psykisk ohälsa till följd av en traumatisk förlossning : En randomiserad kontrollerad studie av internetadministrerad vägledd självhjälpsbehandling

The purpose of this randomized controlled study was to investigate the effect of internet- administered guided self-help for women suffering from psychological problems following traumatic childbirth. The eight-week treatment program consisted of written chapters based on cognitive behavioral therapy. 56 participants were randomly assigned to a treatment group (n = 28) or a waiting list group (n = 28).The results showed that post-traumatic symptoms decreased as a result of the treatment, with large within-group effects measured by both the Traumatic Event Scale (TES) (d = 1.33) and the Impact of Event Scale-Revised (IES-R) (d = 1.3). The difference between the groups was only significant when measured by the IES-R in which case the between-group effect was large (d = 0.97). The proportion of the participants who showed clinically significant improvement was considerably greater in the treatment group than in the waiting list group.

En postindustriell stads dynamik : Kalmars samarbeten och konkurrenser i strävan efter expansion genom handel

The thesis strives to reveal the dynamics between a central and a peripheral shopping area in Kalmar, Sweden. The establishment of larger shopping centers has become a hallmark of postindustrial cities. Cities globally are at risk of creating an urban economic rift between the central and peripheral shopping areas. By establishing major shopping venues around the traditional central business districts, cities hope to create a larger customer hinterland and thereby also increased economic growth. The aim of this thesis is answered by two research questions regarding collaboration and competition between two shopping areas; the central Kvarnholmen and peripheral Hansa City Mall.

Ett resecentrums betydelse för en stadskärna . : En studie om Kramfors resecentrums funktion och relation till den urbana omgivningen, samt upplevelsen av denna

The purpose of this study is to shed light on and describe Kramfors travel centers function and relationship to the surrounding urban environment, and how this core is experienced by residents and visitors. To do this, the use of the travel center, its relationship to Kramfors city center and the perception of it, as well as possible improvement areas has been studied.This has been examined using a quantitative method by designing a questionnaire and the usage of a research strategy through the implementation of a small-scale survey. Within this a cluster sampling was applied.The result shows that Kramfors travel centers is primarily used for traveling and is used most frequently by the visitors within the study. It is also shown that residents 'primary reason for traveling from the travel center is friends and family, followed by shopping, and that the visitors' primary motive for traveling is friends and family as well, followed by work. The mode of transportation between the travel center and destinations are mainly walking, while the mode of transport between homes and the travel center proves to be the car.

Frivilliga avsättningar i gröna skogsbruksplaner - en fallstudie av sex skogsfastigheter samt en enkätundersökning i Östergötland

Frivilliga avsättningar av skog med höga naturvärden är en viktig del för att nå Miljömålet ?Levande skogar?. Det finns dock tveksamheter om de naturvårdsbiologiska kvalitéerna i dessa avsättningar. Syftet med denna studie var därför att undersöka om den skog som avsätts frivilligt av privata skogsägare är den skogsmark som har de högsta naturvärdena på fastigheten. Vidare studerades också markägarens naturvårdskunnande, utbildningsnivå och attityd till naturvård.

Utbildningsnivåns och demokratins inverkan på ekonomisk tillväxt

The purpose with this paper is to examine if tertiary education and democracy have an impact on economic growth. In order to decide how democratic the examined countries are the democracy index constructed by The Economist is used. Besides the two central theories the purpose is also to explain why these variables could affect growth and to examine direct and indirect effects. Indirect effects mean that one variable affects another variable which thereafter has an impact on economic growth.34 OECD countries are compared in order to investigate whether education and democracy are strongly correlated with BNP per capita. Therefore a statistical design is used as method.The empirical results suggest that there is significant correlation between democracy and economic growth.

Genetic variation in local Swedish sheep breeds

Sheep have played a very important part in rural history. In Sweden there were many kinds of small native breeds, kept for their meat and fleece. Women cared for the flock that often had very little to feed on during the cold and sometimes harsh winter months. This meant that these sheep over time acquired special phenotypic properties depending on the environment they lived in, and easily fed compared to modern breeds kept for meat. Most of these sheep have since become extinct.

Folkbiblioteket som socialt rum ? en undersökning av biblioteken i två mindre kommuner

The aim of this thesis is to investigate and increase the understanding of a present function of today´s public library, namely the function of meeting place; here called the social function or social space. Two small town libraries are included in the study, and the questions examined are:How is this function described at the two libraries and what similarities and differences are there between the two? How can one describe the relation between how the library as social space is described in research and at the libraries? The theoretical framework used in examining these questions, consists of three different discourses in culture policy (the discourse of state, market and civil society) and theories on civil society and the public library. A summary of current research makes visible eight different aspects of the public library as a social space. These aspects functions as parts of the theoretical framework as well.
