?Här leker vi inte pang pang Lucky Luke!? : Om pedagogers ambivalens till populärkultur i förskolan

The purpose of this paper is to examine teachers' approach to popular culture in preschool. The questions we want answered are: What approach do educators have to popular culture in preschool and what underlies that approach? Is there a high - and low culture in preschool? If educators bring popular culture into the preschool, how then is it used? Do children?s culture influence everyday life in preschool? We have employed qualitative methods to seek answers to our questions. We conducted seven interviews with educators from four different preschools. The starting point for our study was the socio-cultural perspective because we examined people's cultures and how the meeting between them unfolds. We concluded that educators have a very ambivalent attitude towards popular culture in preschool.

Studier av nitreringskinetiken för järn-kromlegeringar i
ammoniak-vätgasmiljö

Kinetiken för nitrering av en järn-kromlegering med en gasblandning av ammoniak och vätgas har studerats vid temperaturer mellan 500°C och 600°C. För ett gasatomiserat pulver (Fe-7%Cr) har inverkan av syrepotential (H2O/ H2) och olika förbehandlingar (förreduktion och förnitrering) studerats med hjälp av en termogravimetrisk metod. Dessutom har laserablering som förbehandlingsmetod för nitrering av solida ytor studerats med hjälp av GD-OES-analys (Glow Discharge Optical Emission Spectrometry). Resultaten har diskuterats och tolkats med avseende på faktorer som kan påverka ytreaktionens hastighet, kärnbildningsförhållanden samt diffusionsvillkor. Syrepotentialen har visats påverka nitreringshastigheten via komplicerade samband mellan syrepotentialens storlek, kvävehalt i materialet och nitreringstemperatur.

Ett problem för varje lösning : Corrymeela Community, René Girard och den mångtydiga mångfalden

AbstractA Problem to Every SolutionThe Corrymeela Community, René Girard and the ambiguous pluralismThe main purpose of this study is to examine how Girard´s ideas of society, culture andreligion have become part of the reflexion in the praxis of Corrymeela Community through the work of Roel Kaptein and how this praxis can shed light over the work with dissonances of faith and values in education in RE, Social Studies and other subjects.In earlier publications I have studied how dissonances of faith and values can beunderstood in educational settings and in connection with issues of interreligious dialogue.The extensive discussion of how differences in culture, religion and value in a pluralisticsociety are to be analysed and treated in pedagogical reflexion seems to increasingly occupyactors in different parts of the educational system. It is obvious that these issues also arebrought into focus as an important field of research. My main interest in this paper is to study how a reconciliation group in the middle of the conflict in Northern Ireland has developed a view of conflict reason and conflict resolution under the influence of the French researcher René Girard and what aspects of this study that can improve the reflection over pluralism and dissonances of faith and values in everyday praxis in education.For a period of more than a decade I have been in contact with actors in the peace process inNorthern Ireland in connection to different educational projects. The attempts to analyse the different aspects of ?The Troubles? and the efforts to find ways out of conflicts and civil war are many and the literature on subjects related to these tragic history of social, cultural and religious conflicts is difficult to survey.

En studie av Växjö stadspark : med fokus på rekreation och sociala värden

Many people choose to live in urban environments. Since everyday life in many cities is characterized by a high pace it is important that good recreational areas, with the possibility of recovery, are available to the population.This paper is based on a case study of Växjö city park, which is the area surrounding the lake Växjösjön. The park and the lake are of great importance to the citizens. The lake Växjösjön has for a long time been affected by eutrophication, which has caused major problems as algal blooms and fish mortality. An extensive lake restoration was carried out in the 1990s in order to save the lake.

Studie av belagda kolvringarmot plasmasprutat cylinderfoder : Med avseende på friktion och nötningsmotstånd

Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.

Mjölkureahalten som mått på vom-mikrobernas kväveförsörjning och kons miljöbelastning

The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environmental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed. Effects on the reproduction from high ration protein content are also addressed. Dairy cattle are today fed with large proportions of protein which could lead to high expenditure of feed and environmental pollutions. The nitrogen can be lost to the environment by different pathways; leaching, denitrification or by emission to the air.

Utvärdering av effektstyrningssystemet EnergiDirigent® ur ett miljöperspektiv

Energy Director is a control and measuring system for energy consumption and is part of the product portfolio of E.ON AG for more efficient use of energy, offered to business customers. As of today, the system has only one parameter of control, namely power, and the objective of this essay has been to investigate whether other ones could be added. The emphasis is on the environmental perspective, which is why carbon dioxide has served as an example for this parameter in question.Parallel with the study of Energy Director electricity on the margin, calculations of carbon dioxide equivalents and also the Swedish trade of electricity have all been highlighted. Results indicate that when reductions in energy are made it is endorsed to omit from electricity on the margin rather than some mean distributed electricity, under certain conditions, and in addition the calculations of the reductions should be modified regarding the efficiency of the power stations fuelled by lignite and bituminous coal. Sweden practices trade with the Nordic countries as well as Poland and Germany.

Kyrkorestaurering ? problematiken kring kulturhistoriska värden

This thesis handles the problems regarding different value aspects which are applied during restoration and renovation of churches. The curator?s aspects along with the interests regarding change that exists today, is often integrated and is therefore affecting the final results. The thesis aims to discuss the different perspectives and to look at the different values the room possesses. Furthermore, the historical aspects are discussed along with possible strategies to increase a positive outcome of restorations and how to integrate churches to the modern standards in terms of use and allowing them to be a part of a living cultural heritage.Church buildings have historically speaking always had a significant meaning to people, independent of religious belief.

Skogsfastigheter i Jämtland : är det en intressant kapitalplacering i jämförelse med aktier?

Forest as an investment alternative has become more and more popular over the last few years. Between the years 2004 and 2007 increased the price level on forest land with 70 percent in Jämtland. In this thesis a comparison has been conducted between forest in Jämtland and an investment in the stock market. The risk in the two investment alternatives has been included in the comparison. The thesis includes two different studies between the two alternatives.

Kväveförluster och energianvändning på mjölkgårdar i västra Sverige :

Protecting the environment has with time grown to take a more central role in the society. Agriculture plays an important role in the society since this sector produces our food. More thorough research on how agriculture affects the environment is therefore motivated. This research can be used to improve the agricultural practice from an environmental point of view. This is something that both the farmers and the consumers can profit from. This study aims to form the basis for creating environmental indicators for use of nitrogen and energy on dairy farms. Twenty-three farmers in western Sweden have been interviewed about their farms, both organic and conventional. They produce milk with different intensity, defined as the amount of milk delivered (sold) per hectare of arable land.

Dagstidningar och damidrott : En kvantitativ innehållsanalys av genusrepresentationen på sportsidorna i Sveriges största lokala- och regionala dagstidningar

According to earlier studies, men dominates the sports pages in Swedish newspapers. The gender balance is far from equal and the purpose of this thesis is therefore to look into how Swedish local and regional newspapers covered gender in their sports pages during the year of 2013. The study also examines the news values of men?s and women?s sports, whether there are any differences compared to previous studies and whether there are any differences across the country. The study uses a quantitative content analysis and the result is based on editorial material from six randomly selected newspapers in 18 randomly selected days.

"Out of the Closets and into the Streets" : En kvantitativ innehållsanalys om medierapporteringen under Pridefestivalen

This study examines how the media reports on the Pride Festival in Stockholm and what news topics and themes it prioritizes. The purpose of this paper is to examine whether the media coverage of Pride highlights political questions related to social and societal problems. One of the main focuses of the study is on how the media covers male and female homosexuality. The newspapers examined are the tabloids Aftonbladet and Expressen and the respected dailies Dagens Nyheter and Svenska Dagbladet. The study extends over three periods: 19-07-2010 to 07-08-2010, 25-07-2011 to 14-08-2011, and 24-07-2012 to 11-08-2012.Several key theories and themes frame the study.

?Våra långväga vänner": folkbibliotekarierna och de ensamkommande barnen

Purpose: The purpose of the study reported in this thesis is to addto the knowledge concerning what public librarians do to meet theneeds of unaccompanied asylum-seeking minors, thereby helpingthem to develop and establish themselves in a new environment.What tasks, activities and tools do the librarians have at theirdisposal? What problems do they encounter? What values, normsand attitudes guide their work? Method: The thoughts andexperiences of six public librarians have been captured throughqualitative semi-structured interviews, the result of which has beenthematically analysed using notions of social capital and socialexclusion. Findings: Unaccompanied asylum-seeking minors facea number of challenges which the public library with its librarians,collections and various activities can assist in coping with byproviding the children with opportunities to increase their socialcapital and decrease the risk of social exclusion. Researchlimitations: It has for several reasons proven difficult to studyunaccompanied asylum-seeking children as a distinct group, whichis why this study also uses material that deals with refugees as awhole. A significant amount of the latter are undeniablyunaccompanied minors, an especially exposed and vulnerable typeof refugees.

Energimässig jämföelse med investeringskalkyl av två förskolor

This thesis includes an energy survey of the Herrgården pre-school, which has a modern heating- and ventilation system, and a comparison with Östers pre-school which has an older system. An energy survey of Östers pre-school has already been done by a group of three students and all the calculations and values have been collected from that survey. As of today, both pre-schools are heated thru district heating. It will be much easier to make smart and feasible energy-saving-measures by first conducting the energy survey.Herrgården pre-school in Gävle houses 81 children, therteen teachers, one cleaner and one cook. It was finished in the middle of 2009 and the staff has been very pleased with the in-door climate.
