In modernity’s tourism, nature is just a resource. In modernity, enterprises exploit human and natural resources, churning out products to feed the modern desire to consume. In the process, people and nature are carelessly ‘used up’. Thus, Brundtland’s famous exhortation for sustainable development (Brundtland, 1987) remains unheeded, and the rhetoric of sustainable tourism (Bramwell & Lane, 1
The frequent mounting and dismounting the tractor required by many farming operations increases the risk of falls, particularly for older farmers. The present study explored the risk factors related to tractor ingress and egress in older farmers from two countries with a different tradition in terms of safety culture: Sweden and Italy. Eighteen male farmers aged 65 + (8 from Skåne region, southern
Studies conducted in historical populations and developing countries have evidenced the existence of clustering in infant deaths, which could be related to genetic inheritance and/or to social and cultural factors such as education, socioeconomic status or parental care. A transmission of death clustering has also been found across generations. One way of expanding the knowledge on intergeneration
Popular Abstract in Swedish Det diagnostiska värdet av röntgen- och nuklearmedicinska undersökningar kan knappast över¬skattas. Däremot innebär undersökningar som baseras på joniserande strålning en liten risk för patienten att senare i livet utveckla en cancer. Därför är det vår skyldighet att hålla stråldoserna så låga som möjligt med bibehållen diagnostisk noggrannhet. Idag utgör medicinska undThe significant increase in the use of CT, alone or combined with SPECT or PET, has raised concerns about patient radiation exposure and the consequent increased risk of malignancy later in life. The overall objective of this work was to evaluate and optimise different approaches for minimising patient radiation absorbed dose and maintaining or improving image quality in CT, SPECT/CT, and PET/CT.
Feedbacks mechanisms are essential components of our climate system, as they either increase or decrease changes in climate-related quantities in the presence of external forcings. In this work, we provide the first quantitative estimate regarding the terrestrial climate feedback loop connecting the increasing atmospheric carbon dioxide concentration, changes in gross primary production (GPP) asso
Abstract Background: Despite the large availability of 3T MR scanners and the potential of high field imaging, this technical platform has yet to prove its usefulness in the cardiac MR setting, where 1.5T remains the established standard. Global perfusion of the left ventricle, as well as the coronary flow reserve (CFR), can provide relevant diagnostic information, and MR measurements of these par
The aim of this essay is, with reference to a close study on the negotiation delegations of the Tenant Association, to examine the principals of democracy in relation to distribution of power and participation, efficiency and professionalism. This is done with the intention to understand the Tenant Association's view on its own commission as negotiator, according to democracy. The investigatio
The purpose of this thesis is to analyze how the two Swedish reforms, child-care allowance and earned income tax credit (EITC) will affect the labour supply. The child-care allowance will be introduced in Sweden during 2008. The aim is to increase the freedom of choice for parents regarding their child-care. In order to be eligible to the allowance, the children need to be between the ages of one
In this thesis we have discussed if rewards could increase IT acceptance and therein IT use. We have conducted a preliminary study at Alfa Laval in the countries of Denmark, Finland, Germany, Norway, and Sweden. We have specifically conducted telephone interviews with eleven Alfa Laval employees about their use of a Voluntary Computer System (VCS) called IB@WEB. Our main interest was in discoverin
Eftersom snabb teknisk utveckling och globalisering har förändrat sättet på vilket vi anförtror oss personuppgifter till webbplatser för sociala medier samt sökmotorer, har den Europeiska kommissionen föreslagit en ny dataskyddsförordning som kommer att förbättra skyddet för den personliga integriteteten på internet för medborgarna i EU. Då den med stor sannolikhet träder i kraft år 2016 kommer etRapid technological developments and globalisation have profoundly changed the way people entrust their personal data to social media websites and search engines. As a result, the European Commission has proposed a General Data Protection Regulation (GDPR), to enhance online privacy rights for the citizens of the European Union. As the GDPR will most likely enter into force in 2016, one of the maj
Popular AbstractI denna avhandling studeras förhållandet mellan människa och djur, i synnerhet människans relation till lantbrukets djur. Med teoretiska perspektiv från socialkonstruktivism och existentiell fenomenologi behandlas frågor om hur djur och nötkreatur (som utgör en fallstudie) framträder i diskurser och hur de ingår i bönders livsvärldar. Utifrån debatterna om belgisk blå, BSE (galna kThis dissertation is concerned with the relationship between humans and animals. In particular, it explores human relations to farm animals, and especially cattle. The empirical and theoretical work is concerned with how animals appear in discourses and how they form part of human life worlds. Three debates about recent animal-related issues are examined: the introduction of the cattle breed Belg
As the largest single energy-consuming component in most biological wastewater treatment systems, control of aeration is of great interest seen from an energy savings point of view. This paper suggests a simple way of using on-line ammonium measurements to control aeration in a pre-denitrification plant by controlling the dissolved oxygen setpoint. The controller works primarily by feed-forward ba
We investigate whether stellar-mass black holes have to receive natal kicks in order to explain the observed distribution of low-mass X-ray binaries containing black holes within our Galaxy. Such binaries are the product of binary evolution, where the massive primary has exploded forming a stellar-mass black hole, probably after a common envelope phase where the system contracted down to separatio
In this work, a first-order upwind and a high-order flux-limiter schemes for solving the advection–diffusion equation on unstructured grids were evaluated. The numerical schemes were implemented as a module of an unstructured two-dimensional depth-averaged circulation model for shallow lakes (IPH-UnTRIM2D), and they were applied to the Guaíba River in Brazil. Their performances were evaluated by c
The purpose of this study was to develop an understanding of the individual and gendered experiences among young girls and boys who have migrated independently to the city of Kumasi in Ghana in search of work and better life opportunities. The research questions relate to their experiences of opportunities and constraints at destination; self-protection strategies that they employ to minimize nega
Parents have the primary responsibility to create a safe environment for their children. The family is of great importance, both as a basic social unit, but also for the individual child's development. In cases where the parents for various reasons are unable to care for their children and the family environment may be even harmful to the child, it is society's role to take over parental r
Funktionell magnetresonanstomografi (fMRI) är en teknik som gör det möjligt att kartlägga aktivering inom olika delar av hjärnan. Genom att samla in bilddata då patienten är i vila, och sedan jämföra dessa med data insamlade medan patienten är aktiv (t.ex. utför fingerrörelser), kan en bild skapas som visar var i hjärnan aktivering har skett. Dessa bilder kan t.ex. användas för att bedöma om det äFunctional MRI (fMRI) is a technique for determining which parts of the brain are activated when a subject experiences some type of physical sensation or performs an activity. This technique has during the past several years become a very useful tool for understanding functions of the nervous system, and the development of clinical applications is rapidly progressing. However, fMRI is not straight
En ofta använd behandlingsmetod mot cancer är strålbehandling. Inför en sådan behandling undersöks patienten ofta med en typ av röntgenundersökning som kallas datortomografi (eng. computed tomomgraphy, CT). Röntgenbilderna visar hur mycket av strålningen som absorberas av kroppen, vilket innebär att man tydligt ser skillnad mellan ben, som absorberar mer av strålningen än vävnad och luft, som strå
