The effect of cold stratification on germination in 28 cultural relict plant species : with the purpose of establishing germination protocols

Cultural relict plant species from the Nordic countries have been collected by the Nordic Genetic Resource Center (NordGen) for the purpose of conservation. To ensure high seed vitality in store, regular germination tests need to be conducted. It is important to get a correct viability status, but the knowledge of seed dormancy in the cultural relict plants is often poor. The objective of this study was to investigate how seed dormancy is affected by cold Stratification. The study includes 31 accessions from 28 species with the purpose of establishing germination protocols.

Klasskildringar i samtida arbetarlitteratur. En idéanalytisk studie

The purpose of this Master?s thesis is to examine the portrayals of class in four Swedish contemporary novels that have been mentioned as working class literature in the literary public sphere. During the 20th century, society has undergone vast changes due to globalization and technology development. The rise in standards of living for most people in the Western societies has led to changed consumption patterns. In consequence, there has been increased emphasis given to cultural rather than materialist explanations of social Stratification.

Sambandet mellan ökat deltagande på arbetsmarknaden och ett mindre segregerat boende : En studie om boendesegregationens utveckling för flyktingar från forna Jugoslavien i Gävle kommun

Under första halvan av 1990-talet pågick den dödligaste konflikten i Europa sedan Andra världskriget. Som en direkt följd av Jugoslaviens upplösning tog Sverige under kort tid emot över 70000 flyktingar från konfliktområdet. I skenet av dagens flyktingströmmar från konfliktdrabbade områden i Mellanöstern rapporterade Arbetsmarknadsdepartementet 2013 om ett lyckat inträde på arbetsmarknaden för denna grupp jugoslaver. I bakgrund till detta är syftet med denna uppsats att genom statistisk analys undersöka sambanden mellan ett högt deltagande på arbetsmarknaden och en minskad grad boendesegregation. Området för studien är begränsat till Gävle kommun.

Skiktning och strukturell utveckling i unga naturlika skogsplanteringar: :

Multilayered woodland types are an important part of the urban forest. The knowledge how to establish and maintain such plantations are not as deep as other knowledge fields concerning forestry. Therefore this study has looked upon how to achieve multilayered structures in young nature-like woodland plantations. As a theoretical base for the study three different major knowledge culture have been studied that concerns the subject, ecology, forestry and landscape management/design. This three theoretical framework concludes that many natural processes strive in the opposite direction of multilayered structures in their youth.

Inhyrd i arbetsgrupp: en studie av arbetsgrupperna inom Luleå kommmuns vårdcentraler

Samtliga av Norrbottens vårdcentraler har länge haft problem i form av underbemanning av läkare. Landstinget har mött det problemet genom att använda sig av bemanningsföretagsanställda stafettläkare. Vårdcentralernas beroende av stafettläkare skildrades i denna studie ur arbetsgruppens perspektiv. Inom socialpsykologin finns ett flertal modeller för hur bland annat arbetsgrupper fungerar, utvecklas och påverkas. Faktorer som kontinuitet, målinriktning och ledarskap är alla begrepp som kan sägas påverka grupperna.

Sjöars känslighet för klimatförändringar ? vilka faktorer påverkar?

The Earths climate is changing at a higher rate, i.e between 1861 and 1994 the annual mean temperature in Scandinavia increased with 0,68º C and according to recent climate models the annual mean temperature is likely to rise with another 3º C during this century.A warmer climate in many ways is associated with changing conditions for lake ecosystems. An expected higher water temperature and a stronger summer Stratification of the water column increases the risk of anoxic conditions at the lake bottom. Thus anoxic conditions are likely to cause a phosphate leakage from the sediment, i.e. a higher internal loading of phosphate.In this project, the extremely warm summer of 2002 has been used as an example for a possible scenario for a future climate. By comparing levels of phosphorus in the summer of 2002 with a ten-year median value, a phosphorus related sensitivity to climate change has been analyzed for 55 Swedish lakes.

Förändringarna i den tyska familjepolitiken : Ett steg bort från den konservativa välfärdsmodellen?

The purpose of this paper is to analyze the ongoing changes in German family policy. It explores the issue of whether the German welfare state, in this policy field, can still be regarded as a conservative welfare model or rather approaches a more liberal or social democratic model. A qualitative method is used to analyze the material, especially from the German government, including press releases, other public documents and also articles from the political weekly magazines Der Spiegel and Die Zeit. The changes analyzed are the new parental benefit, the expansion of child care, the concept of whole-day schools and the system of joint taxation. The point of departure is Gösta Esping-Andersen?s categorization of three types of welfare states: the social democratic, the conservative and the liberal.

Staten och socionomen. En kvantitativ studie av social bakgrund och välfärdspolitiska attitydmönster bland blivande socialarbetare.

The North-American sociologist Michael Lipsky has characterized social workers as street-level bureaucrats with a substantial discretion in the relationship between the welfare state and its citizens. Within Lipsky´s theoretical framework social workers appear as a powerful group that socializes the citizens to uphold certain expectations towards the welfare state and its (re)distributional programs. From this point of view, it is important to learn more about social workers and the attitudes they express towards the welfare state. The aim of this study is to analyze how the welfare-political attitudes of future social workers are affected by their social background (e.g. class background and ancestral homeland).

Föräldraaktiv tredagarsinskolning och traditionell inskolning ? en undersökning.

 Prostitution has been intensely debated in Sweden for nearly four decades. Two major investigations have so far been initiated by the government and numerous propositions have been put forward in the Swedish parliament resulting in the sexköpslag from 1999 that criminalizes purchase of sexual services. The law aims at punishing the buyer and protecting the women in prostitution, thus making it possible for women to be helped by various social interventions rather than punished. Swedish society has undergone major changes in these decades. Globalization, the internet and the membership in the EU have changed the Swedish society and influenced the discourse on prostitution.This paper has a twofold aim, on the one hand investigating if and how these changes have had an impact on the prostitution discourse in texts produced by the government and analyze how female and male sexuality in connection to prostitution is constructed.

En diskursreglerad v?rld: Makt, kunskap och agens i Mark Lawrence? The Book That Wouldn?t Burn

Historically the library has owned more than silent, book-filled halls; it has been a center for learning and ideas, a source of both freedom and oppression, in other words, a medium for knowledge, truth, and power. Cultures have been divided into powerful and powerless through access to the library's content; those who have - and those who do not have - access to information determine which voices are heard and which are ignored, thus determining the outcome of the future. This thesis investigates how The Book That Wouldn't Burn by Mark Lawrence portrays the relationship between knowledge and power using Michel Foucault's discourse theory. More specifically, how this relationship is manifested through the structures and norms of society, and how the library as a place and institution serves as the means by which this relationship plays out. An established classic like Fahrenheit 451 by Ray Bradbury is placed as a contrasting reference point to help deepen its thematic message of information control and cencurship. Furthermore, the agency of one of the main characters is also examined in the light of Anthony Giddens' Stratification model, as an actor with the potential to move beyond the confines of the power structure. The analysis demonstrate how knowledge, truth, and power remain continuously thematically relevant within literature, and how the reality of our time may be better understood through literary contributions.

Identifiering av konfliktbestånd med hjälp av laserskanning

The interest in harvesting wood fuel in conflict stands has grown in recent years as a consequence of the increased demand for biofuel. Conflict stands are young forests that have not been cleaned and have a large number of stems ha-1with a great height and diameter distribution. This means that traditional field measurements in conflict stands are difficult and very time consuming. Therefore, the forestry sector is in need of new, more efficient inventory methods. In this study, the Lidar data from Lantmäteriet?s (the Swedish mapping, cadastral and land registration authorities) new national height model was used in combination with plots from the Swedish national forest inventory from 2009 to create functions for; height, volume, diameter and number of stems.

Brunnsviken : Utvärdering av åtgärder för förbättrad vattenkvalitet

Periods of hypoxia are a recurring issue in Brunnsviken. Main factors that trigger hypoxia in Brunnsviken are eutrophication  due to anthropogenic emission of nutrients, Stratification in the water column due to salinity and temperature differences  that prevents mixing and a sill inlet that prevents water exchange. As an attempt to improve the oxygen levels, bottom water is pumped from Brunnsviken causing aerated surface water to flow back into the basin.  The objective of this Master?s thesis was to study the change in dissolved oxygen levels due to pumping.
