The aim of this study is to find out if, and in what way the Maasai pastoralists affect the spotted hyena (Crocuta crocuta) through Bomas (Maasai settlement) and keeping of livestock. The study was carried out in the Maasai Mara National Reserve and the adjoining group ranch, Koyake GR, in South-western Kenya.Data was assembled through transect driving, with instantaneous scan sample during two seasons, December 2003 and May-June 2004. Study area contained 12 bomas with three different type of transects each: T1 (0.5 km from boma), T2 (3 km from boma) and T3 (5.5 km from boma), to create a gradual decline in human and livestock impact. Results show that there are differences in the hyena's utilisation of transect type during the day and during the night. The spotted hyena tend to avoid transects close to the boma during the day time, but go there during the night time.

Private individuals can voluntarily buy EU Allowances (EUA) in order to remove them from the European Union Greenhouse Gas Emission Trading System (EU ETS). It leads to progressive reduction of total carbon dioxide emissions in Europe. Kalmar Energi offers customers to obtain one EUA (equivalent to one ton of CO2) per year by paying 25 SEK a month as a KlimatEl-supplement. The purpose of this research is to examine the customers? attitudes in the issue of climate compensation and trying to define the reasons behind their choices.The results of the quantitative questionnaire were analyzed by using descriptive and analytical statistical methods and have shown some correlation between customers? ages and decisions to accept or not the offer of KlimatEl.

The end of the 20th century brought a dramatic change to the music industry. The then predominant models for music consumption and sales were forever altered when the possibility to distribute music over the internet emerged. It has now become evident that it is virtually impossible to stop the distribution of digital music files. Music has turned into a non-excludable and non-rival product, which in economic terms is described as a public good. Public goods theory serves as a starting point for this study, which explores some of the factors that might explain why some consumers pay for music, while others choose to download music illegally.

This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow. To test this, the total phenolic content and protein precipitation capacity was estimated in leaf litter from 13 species in both heath and meadow vegetation across an elevational gradient ranging from 500 to 1000 meters above sea level (m.a.s.l.) in the study region. The results showed that elevation and vegetation type both had a strong impact on both variables. Total phenolic concentrations decreased with elevation for the meadow, and were greater for the heath than the meadow.

The background of this study is an article in the hunting magazine ?Svensk Jakt? where Karl Hedin claims that his sawmills has not noticed any significant moose damages in the timber. The purpose with the study is to find out the causes to the moose explosion and what it has led to in today?s forests. A questionnaire has been sent out to sawmills in the region Dalarna with the purpose of finding out if sawmills receive moose-damaged timber and what they think about how they foresee future development. There were two causes of the moose explosion, that had effects on the moose population. The first cause was that the moose hunters wanted to raise the moose population, and by raising the calf shooting and by saving the cows they succeeded. The second cause was changing methods in Swedish forestry.

The project contains a force analysis of the vertical axis wind turbine Lucia's supporting arms and a measuring device to experimentally measure the forces is made. The forces between the supporting arms and the tower are calculated theoretically and then simulated by a computere. A measuring devise is then designed to measure the forces experimentally. The forces acting on the attachment between the supporting arms and the tower is primarily the centripetal force, gravitational force and the aerodynamic forces on the rotor wings. The maximum forces were theoretically calculated and is 13.38 kN along the x-axis, -0.25 kN along the y-axis and then 0.5 kN along the z-axis.

Prostitution has for a long time been an understudied field in economics. Due in part to a lack of quantitative and empirical material, itself largely a result of the illegality or semi-illegality of the activity in most countries, the factors that explain the prevalence of, and pricing in, prostitution have remained largely undiscussed. In the last 20 year, this have begun to change: new theories ? notably by Edlund & Korn (2002), Rao et al (2003) and Della Giusta et al (2009) ? have been formulated and the rise of internet based escort sites have made large scale quantitative studies possible. This thesis examines if, and in what way, court documents can help expand the understanding of the economics of prostitution in Sweden.

On Nasdaq OMX Nordic Stockholm there has been a large increase in issues of preferred stocks since the financial crisis 2008. Aiming to explain whether preferred stocks have most of their characteristics relating to debt or equity, we answer four sub questions. Do all preferred stocks share the same features, or do they differ from each other? Our population is similar in characteristics, except for the preferred stock of Swedbank which is convertible and deviates when it comes to participation in dividends - instead of convertible the others are limited and redeemable. Further, the second sub question treats preferred stock in relation to the common stock quantitatively, in market data.

In this essay a model of a potential illegal hunter?s decision-making is created and presented in order to provide an overview of important parts of the complexities associated with the current Swedish predator policy. A comparison is made between a livestock owner?s economic incentives, and the expected costs faced by the potentially caught lawbreaker. In accordance with economic theory the benefits and costs of illegal hunting are compared and thus the optimal choice is determined where marginal costs and benefits are equal.

This thesis discusses the Swedish drug policy and its principle of prohibition. In the world of today there is an ongoing discussion about prohibition and the concept of harm reduction. This thesis is an analysis of Swedish drug policy and an investigation as to whether the prohibition concept is in a state of decline. It tries to answer the question; is the Swedish drug policy moving away from its prohibition principle towards a harm reduction principle? The recent debate, articles, documents and earlier research has been analyzed in order to find answers to my questions.

Uppsatsen avser att studera hur geografisk platskänsla spelar in vid olika kategorier av brott. Även undersöks om personer vid lagbrott använder sig av sin vardagsgeografi samt om känslan för rummet och platsen skiljer sig nämnvärt mellan emotionella brott det vill säga brott där känslor ligger till grund (våldtäkt, pyromani etc.), instrumentella brott (inbrott) och instrumentella nätverksbrott (smuggling, langning etc.).Ausonius attentat i Stockholm (1991 till 1992) har använts samt Niklas Lindgrens överfallsserie i Umeå som sträckte sig över 8 års tid. Två personer ombads att utföra en fiktiv brottserie med instrumentella brott (rån och inbrott). Även har en förfrågan skickats ut till KRIS (Kriminellas Revansch I Samhället) om distanser till och från brottsplaster samt känslor inför dessa. Denna förfrågan har även de fiktiva brottslingarna svarat på.Insamling och sammanställning av materialet har pekat på att för emotionella överfallsbrott och instrumentella brott lönar det sig att känna till kopplingen mellan gärningsman och hans/hennes geografi.

The water level of Lake Mälaren has been regulated since the 1940?s. A recentinvestigation suggests that the current regulation needs to be adjusted in order toprevent a decline in water level, salt water from infiltrating from Lake Saltsjön,and risk of floodings. In addition to these preventions, the new regulation couldpotentially effect the natural environment and agriculture practices in the lowlands that surround the lake. The new regulation proposal calls for an increase invariations in Mälaren?s water level during seasons, while the annual mean waterlevel will remain the same.

Freshwater environments are threatened worldwide, of which many of the species associatedwith freshwater. In 2014, 243 freshwater mussels were on the international Red List. One ofthem is the freshwater pearl mussel, Margaritifera margaritifera, which because of itscomplex life cycle can be counted as an indicator of whether a stream is worth protecting. It's since the early 1900's in decline throughout their range. Sweden is counted as a core area which is why we have not only a national but an international responsibility to conserve the species.
