I provide evidence that firms send a negative signal on its non-repurchasing industry counterparts. This is consistent with competitive effects. These negative effects are common for mature firms and are sent by the largest repurchasing firm. The market attributes non-repurchasing mature firms as those ones, which do not maximize value for shareholders because managers have excess cash at their di

Metangas bidrar med en signifikant andel till den rådande växthuseffekten på jorden. I nutid är den största källan till utsläpp av metangas våtmarker i jämförelse med andra naturliga utsläppskällor. Emissioner av metangas från våtmarker är beroende av klimatet och har den egenskapen att ge en positiv återkoppling till klimatändringen. Icke desto mindre finns det dock stor osäkerhet associerat med Popular science Global warming is a significant environmental problem now-a-days. Methane is a major greenhouse gas causing global warming by trapping long wave radiations from the Earth. Presently, natural wetlands are responsible for the largest amount of emissions of this gas when compared to other natural sources. Changing climate impacts the emissions from wetlands which in turn further inten

The term graduation is applied when an industrialized country withdraws a sector or a country from non-reciprocal trade preferences. Sectors and countries are graduated when they supposedly can compete at world market level, but surprisingly little research has explored what effect on export flows graduation actually has. This thesis thoroughly identifies and explains the graduation mechanism, col

This research proposes that an interdisciplinary approach to understanding the concept of culture and culture change could be beneficial for Sustainable Development. It explores the transferability of the DIKT Learning Model and theory of Creative Populations, originally found in management literature, and applies them to a social change corporation in Medellin, Colombia. The corporation analyzed

Utvärdering av olika MR-tekniker som kan se nära höftproteser av metall Magnetresonanstomografi (MR) är en metod för att ta skiktbilder inuti kroppen. Denna metod utnyttjar det faktum att en väldigt stor magnet kommer att påverka vätekärnorna i våra kroppar. Genom att skicka in radiovågor i kroppen kan en spole samla upp den information som studsar tillbaka och med denna information kan man skapa

This paper is concentrated on analyzing the relationship between RMB exchange rate, real estate and stock markets in China. In particular, the study aims to investigate how these three markets are correlated and to what extend RMB appreciation will influence China`s housing and stock markets. Based on the empirical study, I find that the relations between RMB exchange rate, Chinese real estate and

Populärvetenskaplig sammanfattning En multiproxy-analys har utförts genom ordovicium-silurgränsen i borrkärnan Röstånga-1 från västcentrala Skåne. Målet med studien är att förbättra det biostratigrafiska och sedimentologiska ramverket, samt att tolka avsättningsmiljön under detta tidsintervall. Lagerföljden i Röstånga-1-kärnan tillhör det skånska litofaciesbältet och omfattar Sularpsskiffern, SkagA multiproxy study on sedimentary rocks spanning the Ordovician-Silurian boundary has been performed on material from the Röstånga-1 core, with the aims to improve the biostratigraphical and sedimentological framework and to interpret the depositional environment during this interval in Earth’s history. The sedimentary succession in the Röstånga-1 core is developed in the Scanian Lithofacies Belt

“Livet på en pinne” is a Swedish expression for having a carefree life, just like a bird. Unfortunately this is not the case in Sweden anymore. Birds aredecreasing in numbers day by day as a result of our actions and most severe is the situation within the intensified agricultural landscape. The goal with this project is therefor to increase the birds chance of survival by increasing the biodiver

In a world where globalisation generates monotony, industry has looked at the rich cultural past of traditional cultures for inspiration to distinguish its products and services. The growing demand for access to Traditional Cultural Expressions (TCEs) by industry has led to the exploitation and misappropriation of TCEs. Despite huge profits derived from TCEs, indigenous and traditional communities

This thesis was performed and supervised as a collaboration between the Department of Automatic Control and the Department of Electrical and Information Technology at Lund University. The thesis investigates the possibility of utilizing event-based control on a server system, modelling a cloud computing system. The model consists of an extended M/M/1 system with time-varying arrival and processing

Populärvetenskaplig sammanfattning Geoelektriska mätningar med resistivitet och inducerad polarisation (IP) har traditionellt använts för att bland annat hitta berggrundsytor, kartera sprickighet och bedöma deponiers utbredning. Metoden utgår från olika materials olika elektriska egenskaper. I denna studie undersöktes möjligheten att hitta grundvattennivåerna i deponier med denna metod. Vattnet i There is a problem with leachate leakagein the Flishult landfill outside the town of Vetlanda . This means that water that has been in contact with the deposited material is likely to lead contaminants into the surrounding groundwater, causing an environmental impact on the surroundings. This problem is not unique to the Flishult landfill but can be found in many places where there are, e.g., wast

This dissertation is a combination of a quantitative and a qualitative content analysis around the discourse constructed on the website of the European Parliament, specifically concerning the recent economic crisis. I analyzed thirty articles published on the site by the Web Communications Unit in the Directorate General of the Communication of the European Parliament in Brussels. Based on a theor

The aim of this master thesis is to compare two different control algorithms with respect to reference tracking and simulation time for a superconductive cavity in ESS. The two control algorithms are PID and MPC. The most common type of controller is the PID due to its simplicity. However, an increased interest in finding a control algorithm which can handle the reference tracking better than the

Denna uppsats har som syfte att med grund i omfattande kvantitativa data rörande bostadsrättsförsäljningar i Sverige, undersöka hur olika prisbestämmandefaktorer påverkar en bostadsrätts slutpris. Samtliga variabler som kunnat tänkas inverka på en lägenhets slutpris har givits teoretisk anknytning och de hypoteser som ställts upp rörande dessa variabler har även de presenterats med stöd i teorier.

Upprinnelsen till detta examensarbete var att Otis Stockholm, som också leder den svenska verksamheten, saknade en processkarta för nymontageavdelning. Försök hade gjorts tidigare med att göra en processkartläggning, men man hade då inte kommit hela vägen. Man ville nu från ledningens håll ha en karta på processen så att alla gjorde på samma sätt från projekt till projekt. Processen var uppdelad iThe impetus for this thesis was the identification of the need for a process map for processing new equipment within Otis Sweden. The company had tried before to map their process but had not fully developed the model. This time managers wanted a process map to stabilize the process of managing employees to ensure consistency across projects. The process has been spit in two functions, the sales a

Divorced parents with joint custody are expected to collaborate about their children. However, negative emotions are often intense and painful following divorce. This may lead to blocked negotiations about important issues such as children’s living arrangements. The present study focused on the intra-psychic processes of general cognitive-emotional tendencies as they appear over time among low and

Problem description: An optimal layout shall be developed for the plant with respect to the flows of materials, products and staff with consideration to the business, shipping and future expandability. The layout proposal falls into two groups that will interact: proposals for the design of the building and proposals for the layout inside the building. Purpose: The purpose of this thesis is to de

The size and power of tests for smooth structural change are evaluated in the presence of random measurement error in the explanatory variable or outliers in the dependent variable of a univariate regression model. It is shown that the considered tests are robust to measurement error of a magnitude that can be found in real economic data. By contrast,outliers are found to distort both the size and
