Because water is not equitably distributed in time and place, in the right quantity with the adequate quality, water planning and management is used to redistribute the resource in such a way that tries to satisfy the necessities of water users, including the environment. Policies are proposed to improve the water management, however, selecting the best alternative can be difficult when tradeoffs among alternatives improve certain aspects of the planning and management and worsen others. This research establishes a methodology to evaluate water management policies in order to clearly and systematically identify policies that improve the water management. First, each water user, system or environmental requirement are evaluated using performance criteria. Second, performance criteria are summarized using the Sustainability Index. Finally, individual Sustainability Indices are grouped using the Sustainability by Group Index. The Sustainability by Group Index makes it possible to compare groups of water users and regions at a glance. This methodology has been successfully applied in the Rio Grande/Rio Bravo basin, a transboundary basin between the United States and Mexico. A set of scenarios was defined by water users, authorities and environmental organizations of the basin from both countries. A water resources planning model was constructed to represent the water management of the basin. The model was used to evaluate several scenarios and the benefits or damages that each policy provides. Two winning scenarios (called Meta-scenarios) that improve the management for water users, the environment and international treaty obligations were identified. Meta-scenario A is an immediate action scenario that includes: buyback of water rights, improvement in irrigation infrastructure, water demand reduction for irrigation districts in Mexico and the US, groundwater banking and the inclusion of environmental flows. Meta-scenario B is a short term scenario that includes the policies of Meta-scenario A plus expanded buyback of water rights, additional improvements in infrastructure and sharing of water savings between farmers in the US and Mexico. Results have been presented to decision makers and water users in both countries who will ultimately decide if they should implement the suggested policies. Most importantly, some alternative policies are now known that can help to improve the water management in the basin, for whom and where. / text

This study aims to examine how some people in the United States of America during a period of ten years shortly after World War II used motion pictures to spread their political beliefs to the general public. The study also assesses how movies can be used as a teaching method about the Cold War in the subject of history in Swedish upper secondary schools. The main object for the analysis is two movies All the King’s Men (1949) and Rio Bravo (1959), and how they’re used to spread ideological messages to the masses. This study will also try to explain how two political beliefs, communism and McCarthyism rose to such prominent positions in Hollywood. The tools for the analysis of the movies are based on three methods by Jeff Smith about analyzing movies. Furthermore, I’ve presented previous research about films with political messages made during the same period and also what has been said about showing films for educational purposes in the subject of history. The results from this study shows that you can interpret that some films made in Hollywood during the early stages of the Cold War had political messages in them, if you knew what to look for. The results also show that films can and should be used for educational purposes about the Cold War as long as it’s done properly, so that the students can broaden their historical knowledge.

Den hegemoniska maskuliniteten är försatt i ett stadie av konstant förändring och omförhandling. Saker som i en viss tidsepok kommit att associeras med femininitet kan vid en annan tidpunkt komma att tillskrivas som ett maskulint attribut. Då mannens relation till sig själv  – och hans relation till sin omgivning – påverkas av den maskulina idealbild som förmedlas, i bland annat populärkulturellt material, blir det därför viktigt att undersöka hur denna hegemoniska maskulinitet yttrar sig i olika tidsepoker. Detta dels för att utröna varför den ser ut som den gör idag och hur den porträtterats historiskt, men även för att förutspå hur gestaltningen av maskulinitet kan komma att förändra sig i framtiden. Denna studie har utfört en komparation mellan westernfilmer som av diverse forskare och kritiker ses som typiska tidsenliga exempel på filmer inom westerngenren. Detta gjordes för att fastställa hur den historiska porträtteringen av den hegemoniska maskuliniteten skiljer sig från den i ett modernt populärkulturellt material inom samma genre. Detta gjordes genom att utföra en semiotisk bildanalys av protagonistens och antagonistens slut- samt introduktionsscen, därefter jämfördes de observationer som gjorts i analysen, varpå övergripande analyser gjordes, i vilken återkommande drag, behandlingen av minoriteter, kroppsattribut och miljöerna som dessa befann sig i och bebodde, diskuterades och sammanställdes. Kontentan av resultatet var att attribut som tidigare associerats med protagonister i materialet från 1950-talet numera utgjordes av antagonisterna i materialet från 2010-talet. Den tidigare maskuliniteten som gestaltades av storväxthet och breda axlar har förändrats, och den hegemoniska maskuliniteten har nu gett upphov till en man med mer komplexa motivationer, större känsloliv och hänsynsfullhet än den som skänktes av protagonisten i dom tidigare gestaltningarna. Genom att uppnå sina målsättningar kunde även protagonisterna i materialen från båda tidsperioderna dölja att dessa antagit attribut som tidigare varit kvinnligt kodade i den nya maskulina idealbilden, exempelvis fällandet av tårar.
