Forest enterprises have always searched for ways to improve efficiency. For the past few
years there has been an emphasis on stock-keeping levels. Increased demand for fresh
round timber and the need to decrease the amount of tied-up capital has made the forest
industry reduce its inventory levels. This has brought on a higher demand on the timber
supply from the forest management districts concerning both delivery in time and
assortment output. As a result, the flow of timber has fluctuated a lot with serious
consequence for the timber supply during 1994.
"Man kan ju också bygga fler bostäder..." Om hemlösheten i Malmö, ur några kommunalråds och tjänstemäns synvinkel.
This is a qualitative study on bachelor level at the School of Social Work. The aim of the thesis was to describe how selected municipal commissioners and social workers in Malmö view the complex of problems, and different solutions, concerning homelessness.Malmö, the third largest city of Sweden, is struggling with serious problems concerning homelessness. Possible solutions are being debated, and the opinions differ widely, depending on ideological standpoint. We wanted to find out how selected municipal commissioners and social workers view the complex of problems, related laws and local guidelines, and measures to improve the situation. In order to have a free discussion, but within limits we used semi-structured interviews.Our results show that both the municipal commissioners and social workers regarded homelessness mainly as an individual issue, related to dissocial aspects of the individual.
Hassel (Corylus avellana) som indikator på markanvändningshistorik
Hazel (Corylus avellana L.) is a common feature of meadows and pastures where it can grow in large populations and become very old. Is it possible to use the size of hazel stools for age determination and is it possible to use the size distribution of a population to provide information about how the land has been used? Hazel populations on ground where the lake-water level had been lowered, has been studied to validate an already developed growth model of hazel clones. Different hazel populations, on wooded meadows affected by mowing or grazing or overgrown meadows, were studied to evaluate the method utilizing hazel as land use indicator. The growth model was used to compare the size distributions of hazel populations with historical periods, which has been important for changes in agriculture or demography.
En utmanad världsordning- En analys av nya och traditionella biståndsgivares idéer och intressen i det internationella utvecklingssamarbetet
In the past years the traditional donors of development assistance have been increasingly aware of changes in the donor landscape. This as emerging economies like China and India has undergone a transition from recieving aid to becoming emerging donors. By identifying and comparing ideas, beliefs and interests pursued using foreign aid between so called emerging and traditional donors, the greater purpose of this thesis is to take a closer look at the alleged changes in the world order. The starting point is Goldstein & Keohanes framework of the impact of ideas and interests in foreign policy and the one of K.J Holsti about institutions as markers metrics of change. The results show that there is no vast difference in interests but a detectable difference in the ideas behind foreign aid.
Effects of treatment with PiNO (Pulsed Inhaled Nitric-Oxide) on the metabolism in colic horses undergoing abdominal surgery.
The main objective of this research was to study how increased arterial oxygenation by the use of Pulsed Inhaled Nitric-Oxide (PiNO) influenced the metabolic and cardiovascular parameters on horses undergoing acute abdominal surgery because of colic. The parameters blood lactate, blood glucose, pH and heart rate were evaluated before and during anesthesia and closely after recovery. The study showed that blood lactate concentrations decreased significantly during anaesthesia in horses treated with PiNO compared to non-treated horses. It was also seen that the lactate concentration decreased most in horses with the highest levels before PiNO treatment. Since enhanced oxygen extraction ratio was evident in the PiNO group, improved oxygen delivery to the tissue may be a possible explanation for the improved situation.
Trä och fukt ? Mätmetoder för fuktrelaterade dimensionsförändringar hos trä och deras användbarhet, med två fallstudier inom konservering
This thesis deals with different methods for measuring moisture-related dimensional changes ofwood. Typically relative humidity is measured to determine if the ambient climate around anobject is harmful to it or not. Values between 40 to 65% RH are recommended for hygroscopicmaterials. To know how a wooden object actually reacts to changes in the surroundingenvironment requires methods that involve the object itself. Because of the wood anisotropy,differences in wood structure, finishes and other restraints, it is not always possible to predict themovements.This paper addresses various measurement methods, primarily methods that have been testedin the field of conservation, with examples of their use.
Företagskluster och närhet i Katutura, Namibia : En studie kring småföretag, närhet och klusterfördelar
In Economic Geography, there has been a strong interest of how different forms of proximity impacts businesses. In addition, there is also a strong interest in business agglomeration, as a result businesses cluster together through physical proximity, networks and knowledge. In the development sector, there is a strong interest on how to best support the creations and growth of small enterprises.This essay emphasises on the business cluster formations in Katutura, a suburb to Windhoek the capital city of Namibia. It oversees the impacts of different types of cluster formations and their effects on the businesses. In addition, this essay will identify the main clusters in Katutura and state what makes them unique from each other and what is a common cluster feature.

Heuristisk Utvärdering och Användartestning av ett Verktyg för Web-based Training : Korrespondensen mellan Predicerade och Observerade Användbarhetsproblem
Ett verktyg för datorstödd interaktiv utbildning, Web-based Training, har utvecklats på Sigma Information Design. Två olika utvärderingsmetoder har använts för att öka dess användbarhet: heuristisk utvärdering och användartestning. Heuristisk utvärdering är en analytisk metod där expertutvärderare inspekterar gränssnittet för att predicera (förutse) användbarhetsproblem. Användartestning är en empirisk metod där tänkbara reella användare deltar och användbarhetsproblem observeras. Föreliggande studie fokuserar på användbarhets-problem som både prediceras med den analytiska metoden och observeras med den empiriska, så kallade ?träffar?.Analytiska metoder predicerar användbarhetsproblem genom att utpeka bristande ?intrinsic features?(gränssnittsegenskaper).
Utdragshållfasthet hos limmade och olimmade gängstänger i limträ
This essay examines pull-out strength of threaded rods fixed into glulam timber. The technology is intended to be used in hidden joints between glulam components. The work began with a study of literature focusing on current research within the topic, mainly to create a base of knowledge before the testing was initiated. Studies of scientific articles reveals a lack of research within this area, which makes it difficult to develop standards and calculation models for these joints. The drill holes in the tests have a diameter of 7 mm.
Kapitalstrukturens inverkan på företags lönsamhet och värde : En empirisk studie över svenska börsnoterade fastighetsbolag
How capital structure influences corporate performance and value has been in the interest of researchers and scholars for more than half a century, but an answer is yet to be found. The main objective of the present paper is to contribute with data for this cause and hopefully help to clarify this mystery. The method that was used was by analyzing the impact of debt on profitability and market valuation through linear regression. The study examined 17 Swedish property companies listed on Nasdaq OMX Large Mid and Small Cap over a 6 year period (2007-2012). The authors found a slightly negative relationship between debt-to-equity and profitability measured by return on equity (ROE) as well as by return on assets (ROA).

The study also intended to find out how Swedish Facebook users think that companies should behave on their Facebook page.
En applicering av generaliserade linjära modeller på interndata för operativa risker.
Examensarbetet använder generaliserade linjära modeller för att identifiera och analysera enhetsspecifika egenskaper som påverkar risken för operativa förluster. Företag exponeras sällan mot operativa förluster vilket gör att det finns lite information om dessa förluster. De generaliserade linjära modellerna använder statistiska metoder som gör det möjligt att analysera all tillgänglig interndata trots att den är begränsad. Dessutom möjliggör metoden att analysera frekvensen av förlusterna samt magnituden av förlusterna var för sig. Det är fördelaktigt att göra två separata analyser, oberoende av varandra, för att identifiera vilka enhetsspecifika egenskaper som påverkar förlustfrekvensen respektive förlustmagnituden.
Gymnasiebehörighet och sociala faktorer med linjär regression / The Influence of Social Factors on School Performance using the Linear Regression Model.
I det här arbetet har linjär regression använts för att undersöka omolika sociala faktorer påverkar om elever får gymnasiebehörighet. Undersökningen gjordes med kommunvis aggregerad data och faktorerna somundersöktes var utländsk bakgrund, försörjningsstöd, utbildningsnivå, arbetslöshet, disponibel inkomst, lärartäthet, andel lärare med pedagogiskexamen och skolornas kostnad.Statistiskt signikanta resultat erhölls för utländsk bakgrund, försörjningsstöd, utbildningsnivå, disponibel inkomst och lärartäthet. Enligtundersökningen påverkar utländsk bakgrund och försörjningsstöd gymnasiebehörigheten negativt. Utbildningsnivå och disponibel inkomst påverkarden positivt. Lärartätheten påverkar gymnasiebehörigheten positivt omandelen lärare i svenska som andraspråk och modersmål inte överstiger10,4 %.Resultaten för resten av de undersökta faktorerna var inte statistisktsignikanta och därför kan inget sägas säkert om dem utifrån den härundersökningen.Observera att inga slutsatser kan dras på individnivå.
Förstudier av kommersiella fastigheter : En analys av arbetssätt ur ett projektledarperspektiv
This thesis is written at WSP management and investigates the practice of pre-project planning and feasibility studies at Swedish construction companies, through the study of the ongoing feasibility study of the mall Sturegallerian in Stockholm, and through interviews with experienced project managers in the construction industry. There is currently a big span in the way Swedish construction companies plan the pre-project phase and the aim of this thesis is to present a more generic and standardized way that helps minimize project risks and maximize efficiency and profit. The result is a generic model which can be used in pre-project planning. The model describes the phases in the preproject planning process and the activities that span these phases. Is also describes the categories of professions that need to participate in the preproject planning group and which activities that each profession executes. The other result is a list of factors that need to be considered for a well performed pre-project phase, as found during the interviews. Among others the thesis stresses the importance of involving the client as a key participant in the process.
