Har NAFTA-avtalet (North American Free Trade Agreement) som 1994 ingicks mellan Mexiko, USA och Kanada, haft de effekter på den mexikanska jordbrukssektorn, speciellt dess majssektor, som kan förväntas i enlighet med nationalekonomisk teori? Detta är den huvudsakliga forskningsfrågan som denna uppsats försöker undersöka och besvara. Min slutsats är att i fråga om Mexiko är svaret i huvudsak beroende på vilka producenter man väljer att studera. När gäller dess majssektor är effekterna av NAFTA på de konstbevattnade producenterna, företrädesvis i norra Mexiko, mer eller mindre i linje med vad som kan förväntas, medan effekterna på de regnbevattnade producenterna företrädesvis i södra Mexiko ej följer det förväntade mönstret. I en fortsatt analys av NAFTA-avtalets konsekvenser, framstår behovet av statliga interventioner mycket tydligt.

Freshwater ecosystems have long been neglected as an important part of the global carbon cycle. However, research shows that most of the world?s lakes are net-heterotrophic and consequently emitters of greenhouse gases to the atmosphere. In many boreal and north-temperate lakes, most of the yearly emissions usually occur in spring, shortly after ice-thaw. The aim of this study was to quantify the flux of carbon dioxide (CO2) and methane (CH4) in three boreal lakes, during this annual event.

Acidification is a central concept in the environmental debate. The effect of acidification of the soil is a matter of a decreasing amount of cations and thereby a decreasing ability to resist a supply of hydrogen ions to the soil. Acidification has gradually increased in the O horizon in Västerbotten over a 30-year period from the 1970th to the 1990th. The aim of this study was from inventories of The Swedish National Forest Soil Survey and The Swedish National Forest Inventory explain and quantify the acidification that has occurred in the O horizon of two regions in the north of Sweden. Data from SMHI, The Swedish Meteorological and Hydrological Institute, has also been used.

After 9/11 and the following War on Terror, Muslims are often understood as global enemies. However, the idea of an international, Islamic enemy is in some circumstances criticized, not least after the actions of Anders Behring Breivik in Norway in 2011.This study analyses the North American, Emmy Award-winning television series Homeland. It centres on the War on Terror and the following social and political climate, and there are opposing understandings regarding how religion and ethnicity are portrayed in the series. Accordingly, the aim of this study is to analyse how such aspects are constructed in the series. A text analysis is used methodologically and the theoretical perspective contents of Semiotics, Eurocentrism and Orientalism in general, and Islamophobic themes in particular.This study shows that in Homeland, the portrayal of heroes and enemies plus good and evil is complex.

The Swedish Parliament has decided to increase the share of electricity produced by wind power. The same parliament has decided that the Sami have the right to herd reindeer over 50% of the country's land area. In this literature review the potential impact wind power development and associated infrastructure may have on reindeer husbandry conditions are examined. The unique physiology of the reindeer enables it to live out of grazing in the arctic climate in the north of Sweden. For reindeer husbandry to be long-term productive and sustainable, it is important that there is enough land for grazing. The research available on how reindeer are disturbed by human activities such as roads, mines, hikers, etc., clearly indicates that the reindeer avoids areas close to such disturbance.

Site fidelity, the behaviour of animals to return to areas where they have been before is a common trait in many species. The Scandinavian moose is known to show fidelity to its range, but to what extent, is little known. The landscape in Sweden changes in a predictable and unpredictable way and hence gives the opportunity to test the existence of fidelity. I used the kernel Brownian bridge method to estimate the home ranges of individual moose over consecutive years and estimated the overlap at the home range level. I also used Euclidian distance to look on calving site fidelity.

The aim of this study is to investigate the public libraries use of their websites in their marketing. Our study is based on the websites of 60 public libraries. The libraries are chosen because of their geographical location in three different provinces? Skåne in the south, Östergötland in the middle and Norrbotten in the north. These three choices enable us to cover densely as well as thinly populated areas, the agricultural district, the woodland and cities of various sizes.

Partnering is a new and exciting way of cooperation in the Swedish construction industry. In countries like Denmark and the United Kingdom the concept has been developed during a number of years while the Swedish construction industry has been more reluctant.Partnering is seen by many as the solution to the problems that often occur in design and build contracts. Many others believe that it is a way for the big entrepreneurs to gain unfair advantage. Never the less the concept is fast getting more and more appreciation, especially in the region of Karlstad where many new buildings are built that way.We have focused on the new development of Carlstad Conference Center (CCC) which is currently built with a partnering concept. The main method that have been used in this thesis are interviews with personnel on different positions in the project.

Intimate partner violence is a problem which is increasingly drawing attention in society. The authority responsible for providing care and support to victims of intimate partner violence and their children is the social services. The purpose of this study was to show how social workers deal with intimate partner violence and to create a description of how this work is currently carried out in seven municipalities in the north-west of Stockholm. This was done through a quantitative survey including all investigating social workers in the municipalities concerned. The results were analysed with concepts from organizational theory.

Abstract? ?there is no reason?to assume that prehistorians cannot study ancient symbolism and beliefs. The question remains, however, how best to study symbolism within the material confines of archaeological research?(Fogelin 2007:63)With my essay I would like to bring up the meaning of the soapstonelamp for the Thule culture in Greenland. Humans in the arctic area, from the same in the north of Scandinavia to the inuites in Greenland, have a common way of viewing the world that stems from anemismen.

Competence Portals are software tools that are intended to make it easier for persons that have had no previous contact to find and contact each other. The portals can address areas ranging from finding an expert within an organisation to the marketing of the competence of a region or a research centre to other organisations. The purpose of the thesis is to examine the necessity of Competence Portals in research-intensive organisations. Important characteristics of the information in such portals have been identified and used as a basis for recommendations regarding how Competence Portals could be designed. Furthermore, the thesis focuses on the task of finding a source of knowledge within an organisation.

In the report parasites in the gastrointestinal tract and easily visible external symptoms of disease in capercaillie, (Tetrao urogallus), was taken into account. The study was based on results from the examination of 62 fresh faecal samples, collected in spring 2003, and postmortem examination of 22 frozen birds that were collected between 1999 and 2003. All of the samples principally were from the north of Sweden. In total, 4 species of parasites, but no significant symptoms of disease were found. In the faeces low levels eggs of the roundworms Capillaria spp. (125 epg) and Ascaridia spp.

The effects from a planned wind farm on the grid utility Gävle Energis electrical grid have been studied. The wind farm is planned to be built in the forest 15 km north of Gävle and will have 23 turbines with rated power from 2 to 2.5 MW, resulting in a total installed power between 46 MW and 57.5 MW. The grid connection will be made at 70 kV. The aim of the analysis was to determine what effects the wind farm would have on the power grid in the form of electrical disturbances (flicker etc.), need for new investment and raised operational cost. To allow the connection of the wind farm technical solutions (new lines, power stations and grid reinforcements) have been constructed.

The goal of the society to increase the proportion of renewable energy has led to an increased demand of bioenergy e.g. forest biomass. However, there are concerns that removal of biomass will lead to decreased base cation concentrations in the soils and acidification of streams. In order to find in which types of landscape removal of branches and tops could have such negative effects, this study aims to analyse the relations between pH-sensitivity and landscape variables in the Bothnia Bay water district. GIS and digital geographical data were used to analyse the landscape in subcatchments.
