Tjetjenienkrigets inverkan på den ryska demokratin
Detta arbete behandlar Rysslands demokratiseringsprocess, och syftar till att studera vilka inslag av demokrati som förekommer i dagens ryska samhälle samt utröna vilka komplikationer Tjetjenienkriget fått för dess utveckling. Demokratibegreppet har vi delat in i tre avgränsningar, det politiska samhället, det civila samhället och det rättsstatliga samhället, vilka analyseras var för sig. I det politiska samhället behandlar vi frågor om Ryssland relationer med omvärlden samt konsekvenser av politisk ojämlikhet. Det civila samhället tar upp den ryska medieapparaten samt människornas rätt att organisera sig i sociala ickestatliga organisationer. Rättsstaten behandlar vikten av att ha ett stabilt regelverk samt betydelsen av dess efterlevnad.Resultaten tyder på att Tjetjenienkriget haft stor inverkan på demokratiseringen då det inneburit en degradering av den ryska rättstaten genom alla övergrepp mot civila som begåtts i samband med konflikten och lett till allmänt ökad brutalisering i det ryska samhället.
Bottensubstratets inverkan på föryngring av Flodpärlmussla
The freshwater pearl mussel (Margaritifera margaritifera) is threatened throughout its range. There has been a substantial decline of the species and one major reason is habitat degradation. We investigated how the substrate composition of the bottom floor affects the regeneration of the mussel by analyzing data from the Västerbotten County Board?s inventory of the freshwater pearl mussel. The results implied that fine material such as fine sediment and sand might be detrimental to regeneration whereas gravel and boulders and in particular stone seem to be beneficial.
Konduktivitet i vattendrag som indikator på sura sulfatjordar
Increasing attention is being given to acid sulphate soils wherever they occur. The problems that leaching sulphate soils gives with significant lowerings of pH and mobilization of heavy metals influence large spectra of our society from fisheries to agriculture to construction. Mapping these soils is consequently of great importance and the methods of doing this is very much lacking in function and precision. This study was therefore carried out to investigate whether conductivity in running water can be used as a simple instrument to identify acid sulphate soils in the catchment. 31 coastal streams in the county of Västerbotten were analyzed for different catchment properties such as occurence of marine sediments and basic water chemistry including conductivity and sulphate.
En diskursanalytisk studie om Israel-Palestina konflikten : en studie om sexdagarskriget och intifadan utifrån Dagens Nyheter
Israel-Palestina konflikten är en av de mest debatterade konflikterna i massmedia. Konflikten bevakas världen över och har varit studieobjekt för många forskare. I denna uppsats undersöks framställandet av sexdagarskriget 1967 och intifadans inledningsfas 1987 i Dagens Nyheter.Materialet analyseras utifrån Norman Faircloughs tredimensionella modell som sedan placeras i en större samhällig kontext. Björn Hettnes modell om världsordningen har använts för att få ett större samhälligt perspektiv. I uppsatsen redogörs för den kritiska diskursanalysen och den tredimensionella modellen.
Indexering av humanistisk litteratur och humanistiska databaser ? exemplet MLA International Bibliography
This thesis aims to answer the following questions: What type of vocabulary is used in the humanities? What does this implicate when it comes to indexing in the humanities? How do humanities scholars seek information and what type of information do they need? What consequences does this have when it comes to the development of humanities databases? How is the MLA International Bibliography organized? How does its indexing system ? CIFT ? work? How does the MLA International Bibliography correspond with the needs of the humanities scholar? The study shows that the type of vocabulary used in the humanities differs significantly from that used in the sciences. Therefore, information retrieval is often said to be problematic in the humanities when compared to the sciences. This is, however, not completely true. If consideration is taken to the different type of vocabulary used in the humanities, subject access proves to be more straightforward than has been generally recognized.

Dolt under ytan : intrycksstyrning som ett redskap för att dölja ett sjukdomstillstånd
Fitting in is something that many strive for in today?s society. In order to do this, more or less all of us use impression management. The illness Anorexia contradicts the norms of society since eating is a fundamental need, and to refrain from this is therefore a major discrepancy. It is the impression management among anorectics we have chosen to put our emphasis on in this survey in which about ten people have been interviewed with a qualitative method.
"Kvinnor, invandrare & andra handikappade" En diskursanalys av "mångfald" och "jämställdhet"
Denna studie är ett alternativt synsätt på en kommuns mångfalds- och jämställdhetsfrämjande. Vår uppsats är en diskursiv analys av de normativa föreställningarna kring begreppen "mångfald" och "jämställdhet" med vilken vi uppmärksammar hur det till synes positiva mångfalds- och jämställdhetsfrämjandet i själva verket inbegrips av negativa inslag.Vi granskar inte bara hur interaktionen fungerar mellan dessa värdeladdade begrepp utan också effekterna därav. Studien avgränsar sig till Landskrona kommuns mångfalds- och jämställdhetspolicys, med intervjuer som kompletterande inslag, genomförda med strategiskt utvalda representanter från kommunen. Genom den här uppsatsen uppmärksammas de bristfälliga perspektiven som råder över begreppen "mångfald" och "jämställdhet". Dels belyser vi hur begreppen i sin samverkan interagerar som exkluderingsmekanismer och reproduktioner av rådande maktförhållanden.
Alla ser såren, men det är inte där det gör ont: en studie om varför flickor skär sig och adekvat behandling
The aim with this study was to examine professional peoples' view on the reason why females, under the age of 18 years old, self-harm and the professionals view on their treatment. The study is qualitative and based on eight interviews with professional personnel who work with young females with self-harm behavior in the region of Skåne. To be able to analyze our qualitative interviews we used two theories; the attachment theory and trauma theory. The results of this study show that there are many different functions with the self-harm behavior and that the cause of the behavior can be different among the females. Most of the young females seem to self-harm to reduce anxiety but some also do it to punish themselves, to feel alive or to belong to a group of friends.
Den ideologiska spegeln - en studie kring hur ideologisk-diskursiva ramar skapas inom ramen för ett politiskt parti
AbstractOne aim of this thesis, has been to explore how discursive frames are constructed, frames to relate to, compare with, and therefore be part in shaping political subjects. The other aim has been connected with a more empirical platform, where I wanted to discover how these frames are established and structured discursively within a political organization, among its members; in this case with a foucs on the Swedish social democracy and its former leader Olof Palme. The thesis starts with a theoretical presentation and discussion, where focus is on the concepts of ideology, discourse theory in the form of Laclau and Mouffe, and narrative theory. The concepts will be presented and discussed, and also related to the other concepts to see their theoretical potential, both ontologically and epistemologically. Finally the theoretical rudiment is linked and analyzed with the empirical material.
?It?s like liberation? : a study of agricultural knowledge dissemination among small-scale farmers in Tanzania
The following essay is a descriptive and analyzing study in how the local Tanzanian NGO MVIWANYA works to disseminate sustainable agricultural technologies to the farmer households in Rorya District, Mara. It also presents and analyzes the reception and impacts these new technologies have on the households. Information was gathered during two weeks of field work at the organization in Tanzania. It was conducted empirically through interviews with and observations of small-scale farmer members of MVIWANYA and the staff of the organization. The gathered material is analyzed and presented with the help of a theoretical model designed by Birner et al.
Typ av demens relaterad till övriga sjukdomar och tidigare genomgången anestesi/kirurgi : En retrospektiv pilotstudie
This retrospective study reviews and investigates type of dementia, related to co morbidity, symptoms of dementia, previus anaesthesia/surgery, intraoperative events and postoperative cognitive symptoms. The patient co morbidity was compared to occurrence in an age-matched population of 1095 individuals. Fifty-two patients with different types of dementia participated. Data was collected from patient journals.Compared to population, heredity for dementia, heart insufficiency, hypertension, depression and B12- deficiency was more frequent in the patients. B12- deficiency was common in vascular dementias and "burn-out syndrome" in early-onset AD.
Konflikten i Colombia - en studie av faktorer i nya krig
Det har i Colombia sedan 1960-talet pågått en konflikt mellan regeringen och olika väpnade grupper. Konflikten har visat sig vara svårlöst.Vi har utgått från Mary Kaldors teori om nya krig för att analysera vilken roll olika faktorer har spelat i konflikten, för att sedan kunna dra slutsatser om de har försvårat en konfliktlösning.De väpnade gruppernas ökade inblandning i narkotikahandeln har lett till att de har kunnat finansiera sin fortsatta krigföring. Konsekvenserna av detta har blivit att de delvis frångått sin ideologiska målsättning, då de tjänar på att upprätthålla konflikten. Vidare har våldet mot civilbefolkningen ökat, till följd av gruppernas nya krigföring där erövring av territorium sker genom folkfördrivning och mord.Den colombianska regeringens strategier för bekämpning av de väpnade grupperna har förändrats för att svara mot det nya konfliktmönstret. Regeringens strategier har möjliggjorts till följ av den internationella bekämpningen av terrorism.
Marknadsmässig spannmålshandel
The agriculture throughout the world is becoming increasingly deregulated and this has affected the prices of raw materials to fluctuate at a higher degree than earlier. This in turn has made it interesting and in some cases even necessary for the trader as well as the
producer to gain knowledge about the trade instruments available to ensure a good enough price for their produced goods. This study encompasses a number of ways to
trade grain and oil plants in order to clarify what differences there are in the several contracts that exist in the present situation, economical as well as practical. The various trade instruments available to the producers on the Swedish market are described in the theoretical part of this study.
The study also contains a simple arithmetic example, based on historical prices collected from grain traders and trading floors, in order to point out the differences in the
economical outcomes depending on the business strategy used to sell the produced goods.
The study shows the importance, as a producer, of being able to use and take advantage of the different trading instruments at hand to monitor and exploit the shifts in the
market. From an economical point of view it is not enough to just excel at farming but knowledge about the market functions and the trade instruments at hand is also required
to be able to secure a good enough price for your goods.
