Impacts of stressful weather events on forest ecosystems in south Sweden

Coniferous as spruce (more specifically Norway spruce, Picea abies) and deciduous species like European beech (Fagus sylvatica) and oak (Quercus spp.) co exist in south Sweden. In perspective of climate change, species composition of Swedish forests is assumed to change. Observed climate on the period 1950-2010 prove that a general warming trend is occurring in southern Sweden, and that vegetation

Assessment of climate change impacts on cork oak in western Mediterranean regions : a comparative analysis of extreme indices

Mediterranean regions have a growing number of extreme weather events due to rapid change of climate. Cork oak, which is located in the western Mediterranean area, has become a very valuable resource within the western Mediterranean forests. Therefore, assessment of the impacts of climate extremes upon cork oak can help us produce better forest management practices for coping with future climate c

Social Economy-Based Microenterprise as an Alternative Community Development Model- a Case Study in Rural Peru

This thesis examines the potential of a social economy-based microenterprise model as a new community development tool in the special context of indigenous Quechua communities in rural Peru where their socio-economic realities are substantially different from the modern society. Although, the social economy-based development policies are widely discussed in many Latin American countries, only litt

Comparison of vegetation indices to determine their accuracy in predicting spring phenology of Swedish ecosystems

Phenological observations of terrestrial ecosystems are useful in monitoring the changes in the local climate due to their relatively long time series and high temporal resolution. However performing field based phenological observations can be a labour intensive and time consuming process. Using satellite-based remotely sensed data can make the process much more efficient. Although the satellites

Comparison and validation of five land cover products over the African continent

Scientific abstract: As the increasing attentions drawn to the environment and climate change issue, the profound impact on the earth system made known to nearly every corner of the world. A great variety of global protocols and conventions has been established aiming to reduce global environmental risks and maintain a healthy earth system. In order to monitor, supervise these protocols and conven

Attachment organization and perception of constraining and enabling factors in long distance relationships: A first step towards constructing an instrument to measure experiences of living in a long distance relationship

Living in long distance relationships (LDRs) has become a common phenomenon worldwide. LDR couples continously move in and out of each other's co-presence, and research has shown that the transitions between togetherness and separateness give rise to factors experienced as both constraining and enabling. The present study extends LDR-research done by Sahlstein (2004) by taking attachment organ

Vegetation indices, FAPAR and spatial seasonality analysis of crops in southern Sweden

Remote sensing is an extensively used technique in ecosystem monitoring or analyzing the carbon balance on the earth surface. The most dominant part of south west Skåne is agricultural land and MODIS derived Vegetation Indexes (VIs) are able to investigate the seasonality of crop fields. The values of VIs represent the different stages of spring greening up of crops and it shows the non-linear and

United States extraterritorial application of economic sanctions and the new international sanctions against Iran

Economic sanctions are defined as the exercise of pressure by one state to produce a change in the political behaviour of another state. Traditional economic sanctions are directed at the entire population of a state whilst targeted sanctions are directed at a state’s individuals. This thesis discusses the application of economic sanctions against Iran by the UN, the EU and the United States. Econ

Arbetstagares yttrandefrihet och kritikrätt vid användning av sociala medier

I denna uppsats undersöks rättsläget för arbetstagares yttrandefrihet och gränserna för kritikrätten vid användning av sociala medier såsom Facebook och bloggar. Arbetstagaren har en plikt att vara lojal gentemot sin arbetsgivare. Lojalitetsplikten utgör en samlingsbeteckning för en rad olika förpliktelser, t.ex. tystnadsplikten och den närliggande skyldigheten att iaktta begränsning i kritikrätteIn this thesis the employees’ freedom of expression and right to criticize the employer when using social media such as Facebook and blogs is examined. The employee has an obligation to be loyal to his or her employer. The concept of loyalty covers many different obligations, for example the duty to respect confidentiality and the closely related duty to not criticize the employer, the employer’s

The Abolition of the Nautical Fault Exemption: To Be or Not To Be

Historically, the nautical fault exception was justified on the basis that shipowners lacked the ways to control their ships by communication on long voyages and so masters had to act in their own judgement. Modern communications have defeated this underlying rationale but shipowners still want to claim the benefit of the exception. As a matter of statutory regulation, the exception traces back to

En studie av möjligheten att öka den värmelagrande förmågan hos betong

Tunga byggnadsmaterial som betong har hög värmekapacitet och bidrar till att ge byggnader en termisk tröghet. Byggnadernas temperatur ändras inte så snabbt när utetemperaturen förändras eftersom betong kan innehålla stora mängder lagrad värme. Detta kan ofta ge positiva effekter på energiförbrukning, termisk komfort och effektbehov. I denna studie undersöktes möjligheten att ytterligare förbättra

Key issues for companies entering the Chinese WEEE recycling industry

Problem: The Chinese WEEE recycling market is today operated mostly by the informal sector. As this sector eludes the insufficiently enforced environmental laws the e-waste is recycled by means not only harmful to the environment and people working with the recycling process, but it also utilizes methods that do not recover valuable materials in a sound and efficient way. Many companies stand read

Västsaharas legitimitet som stat- En undersökande fallstudie om Västsaharas möjligheter att bli en stark stat

The status of Western Sahara has since 1975 been a controversial topic in international relations. Morocco claims that the territory rightfully belongs to them while Polisario, the representative of the Sahrawi’s, are of the dichotomous opinion and demands independence. In this paper I will examine the statement that Western Sahara in the long run would be to weak and too poor to survive as a stat

A sourcing evaluation model for transportation and installation services of wind turbines - The case of E.ON Vind Sverige AB

Today’s global competition forces manufacturing companies to re-evaluate their existing processes, technologies, manufactured parts and services in order to focus on strategic activities. The question whether to make or to buy goods or services represents a problem faced by many companies when deciding between keeping technologies/processes in-house or purchasing them from an outside supplier. In

Sponsring - Avdragsgill marknadsföring eller gåva? Den skattemässiga behandlingen av sponsring

Sponsorship is currently a concept to be reckoned with. The development has been rapid in recent decades and the law has still not brought complete clarity whether sponsorship should be seen as promotion or gift. There is evidence that sponsorship cannot be seen in black or white. The right to deduct that exists for the promotion does not apply to gifts, which can have a major impact on the sponso

The Remnants of Political and Trinitarian Structures in the Post-Cold War Era

The purpose of this thesis is to provide a contribution to the current waged debate concerning the validity of Carl von Clausewitz’s theories regarding actors engaged in the acts of war. These thoughts have been suggested to be obsolete in the post-cold war era whereas the new wars theories have emerged and modified and challenged the classical knowledge of the very nature of war. The theoretical

Friend and/or Foe?

The U.S. adaptation to the provoked insurgencies in Afghanistan and Iraq has led to a new groundbreaking doctrine focusing on this “new” insurgency warfare. Counterinsurgency, or COIN, has become a beacon for Western states battling rogue and disparate insurgents. In the cases of Afghanistan and Iraq, PRTs have been chosen to be on the frontlines in this guerilla war. This study mainly seeks to di

Utprovning av nytt betong -proportioneringsprogram anpassat för krossballast

Sammanfattning Vid betongtillverkning används i Sverige idag stenkross som grov ballast, medan det främst är naturgrus från rullstensåsar som nyttjas till den finaste ballasten (stenar som är mindre än 4 mm). Det sistnämnda börjar dock lokalt ta slut och ersättningsmaterialet som finns i tillräcklig mängd och inom rimligt transport-avstånd är grus från krossat berg. Dock har det visat sig att beto
