Historiska berättelser ? en användbar undervisningsmetod?
Undersökningen gick ut på att undersöka om historiska berättelser är en relevant undervisningsmetod för att öka elevers historiemedvetande och fördjupa deras kunskaper. Kunskaper ansågs i detta fall vara fördjupad förståelse och empati samt faktakunskaper. Även elevers och lärares syn på undervisningsmetoden undersöktes. Undersökning skedde på en mindre skola i nordvästra Skåne i två niondeklasser. En berättelse och en Power Point konstruerades och den ena klassen fick lyssna till berättelsen och den andra till Power Point undervisning.
Bitchblickar och giftpilar : En kvalitativ undersökning utifrån skolpersonals tolkningar av fenomenet mobbning bland flickor
The purpose of this study was to examine how school personnel describe and interpret the phenomenon bullying among girls, and also what their interpretations are based upon. More specifically its aim was to find out what characterizes and causes girl-to-girl bullying, according to school welfare officers and teachers. We wanted to find out how school personnel look upon aggression among girls and social expectations on girls behavior. The analysis was based on two kinds of perspectives: one focusing on gender and one focusing on power in relationships. Research shows that girl-to-girl bullying is hard to observe and that this problem has been invisible in earlier studies.
Implied Dividends and Equity Returns
This paper studies the option market?s implied dividend as a predictor of future equity market returns. We introduce this variable in the simple total return framework and discuss some complications of using it as a proxy for the expected dividend. We construct some regressions using the price-dividend ratio and the implied dividend growth, and test them on six years worth of data on the EURO STOXX 50-index. The main result is that implied dividend growth exhibits some forecastability over two-year horizons, but that the dataset is too short to draw any definitive conclusions about long-horizon forecastability.
När vikten blir det viktigaste
The aim of this investigation work " What was it called...Equality...? is to study a clinics current gender equailty plan from a gender approach and by a field survey see if, and in that case, how it can be improved. A connection between existing gender norms and gender power strukctures is applied in the results of this survey in order to illustrate their significance from an individual as well as a structural perspektive.The survey has been carried through by a field survey as well as a discourse analysis as method. Yvonne Hirdmans gender power system is on of the main theoretical points of departure.The results that I have achieved in this essay is that gender can be looked at in different ways within the labour market where women have the main responsibility over the family and are considered more nursing then men. Men on the other hand are thinking of their carriers and have higher salary requirements.
Fo?rutsa?ttningar fo?r elektrifierade lastbilar med eHighway inom svensk gruvindustri : En ja?mfo?relse av olika transportslag mellan Mertainen och Svappavaara
The Swedish government has a goal of achieving a fossil-free vehicle fleet in 2030. Heavy transport constitutes a significant part of Sweden's transportation sector and the vehicles are driven almost exclusively by fossil fuels. Siemens has developed eHighway, a concept for electric road systems enabling electrification of trucks, in order to reduce the environmental impact of heavy transports. This study aims to investigate the potential that eHighway has on transporting iron ore from the mine of Mertainen to a processing plant in Svappavaara. Electrified trucks are compared with conventional trucks, and diesel and electric trains.The evaluation was made with respect to energy consumption, environmental impact, and cost.
Pellets - en framtidsmarknad?
With higher prices for oil and increased focus on fossil fuels impact on the environment the heating sector are searching for alternative fuels. Pellets are a quite new product whose production has risen exponential in recent years. Today there are small-, medium-and large-scale users, where the large-scale consumers are the heating sector. The heating sector is mainly using oil to cover the increased demand during cold periods.
The purpose of this study is to analyze the potential of pellets if it would replace thermal power plants oil and coal. The study will also analyze the economic impact a conversion would mean for a heating plant and if the pellet is a reasonable substitute.
2008 statistics from the Swedish district heating association were analyzed and a calculation was performed to determine how many tons of pellets is needed to replace coal and oil.
Hur hållbar är serogrisproduktion? :
Raising pigs in absence of a number of certain diseases is called Seroproduction in Sweden. Internationally it?s called SPF (Specific Pathogen Free) ? Production. It results in higher growth, lower feed consumption, and lower medicine consumption. The pigs are produced under the same concept, but the rules vary a bit between countries.
Vakuumbrytare i småskaliga vattenkraftstationer
This master thesis has been performed at Vattenfall Power Consultant in Gothenburg and Trollhättan for Vattenfall Vattenkraft. In this report vacuum circuit breaker in small-scale hydropower stations with the rated power 4 MVA and below has been studied. Models of the stations are modeled and analyzed in PSCAD/EMTDC to study the high voltage transients that are created after current chopping with vacuum circuit breaker. Vacuum circuit breaker may chop the current before it reaches zero value, which means that high voltage transients can be created. The equipment of the stations can be destroyed by high voltage transients.The purpose of this thesis is to examine the use of vacuum circuit breaker in small-scale hydropower stations and the risk for high voltage transients from current chopping.According to the results there is a risk of high voltage transients after current chopping with small synchronous generators in stations with the operating voltages 0.4 kV and 3.6 kV.
Vad privata angelägenheter sysslar den anställde med på arbetstid och varför? : En kvalitativ studie
Sarah Kane?s first play Blasted (1995) has often been read in a normative and biographical way by critics, authors and previous researchers. This essay makes a supplementary close reading of Blasted from gender and genealogical perspectives and utilizes theoretical works by Judith Butler, Luce Irigaray and Michel Foucault. My study makes clear that the characters different positions in language and talk create and maintain a power imbalance between them. Efforts to change and develop one?s individual position in language and talk are being made throughout the play since it is the only way to bring about a change in the social power structure.
Kommun och landsting - Vem har mest makt? : en kvalitativ studie om den samverkan som sker mellan dessa organisationer vid vårdplaneringar kring äldre personer i Sverige
This essay?s focus lies on the collaboration that takes place in hospitals and called a care-plan (vårdplanering) between the two organisations: Health-care (landsting) and social-care (kommun). According to the Swedish-law are these organizations responsible for the care of elderly individuals in Sweden. The aim of this essay has been to study closely this collaboration in order to see which partner has the most influencing power.This essay is of a qualitative character, which means that the results that are presented are based on six individual interviews with employees from the two organizations. The employees chosen for this essay all have job experiences from the collaboration that takes place during care-plans in hospitals.One of the main results of this essay has been that the two organizations are not equal collaboration-partners.
Framtidens energilagring : en studie av befintliga samt potentiella metoder fo?r lagring av fo?rnybar el pa? ett ha?llbart sa?tt
In today?s society there is an increasing demand for renewable energy sources such as sun and wind power. These sources are intermittent, and energy storage is therefore needed to ensure a constant power supply. This report compares pumped hydro energy storage (PHES), compressed air energy storage (CAES), flywheels, batteries, super magnetic energy storage (SMES) and hydrogen energy storage.The opportunities for further development are limited for PHES and CAES in comparison with the other technologies. Lithium-ion batteries and hydrogen energy storage are considered to have the most potential in the future.
"Dilemmat i tillämpningen av tvångsvård" : En kvalitativ studie utifrån åtta socialsekreterares perspektiv
The overall objective of our research is to understand how social workers in social services protect the individual's autonomy, integrity and a coercive law which deprives the individual of his rights.In this study, we bring out social secretaries perspective on how they see the compulsory treatment and the problems that can arise in a detention. This study is based on the questions; How are power between social worker and client? What is the social secretary of the law on compulsory as a tool to help clients?We interviewed eight social workers who work specifically with compulsory treatment. We used the result to answer our questions. As a theoretical background, we chose to use the power perspective, the concepts of flexibility and freedom of action and categorizations.The results that emerged from our study are that compulsory treatment is considered to be a positive and negative thing.
På klasskampens väg : Tidningen Gruvarbetarens inställning till strategier och mål för arbetarrörelsens fackliga och politiska kamp 1917-1925
Abstract: The aim of this study is to investigate the attitudes towards the labour movement?s strategies, goals and organisational issues in Swedish Miners? Union?s (Gruvindustriarbetareförbundet, hereafter Gruv) paper, Gruvarbetaren 1917-1925.The theoretical starting point is Engels? view on the class state. This perspective turns the question of socialism and the way to get there into an issue of working class power over the state. Another theoretical perspective is the partition of the labour movement into a trade-unionistic branch, seeing unions as financial organisations of interest, and a pro-state one, considering unions as political organisations.During the period investigated Gruvarbetaren was quite radical and advocated a firm class struggle strategy towards employers. Since these were considered unreliable, class struggle was seen as the only way to better the conditions for the working class.
Repulsion : Subjektivitet och frågor kring det sociala
The scope of this investigation is the conditions under which readings of Repulsion (1965), and its depicted mental illness, took place in Sweden during the censorship debates in 1965, and also how the reception was related to narration and subjectivity in the film. The reason for this is the strong reactions to the images of the main character?s inner state, and concerns about negative effects in the public, that were raised. One major concern is how the film articulates discourses through which meanings are produced; that is, how it works as social technology. My thesis is therefore structured around two levels; textual analysis and discourse analysis.
Dragshow på de sju haven : ? en analys av Elizabeth Swanns karaktär i Pirates of the Caribbean
AbstractTitle: Dragshow on the seven seasNumber of pages: 51 (56 including enclosures)Author: Therése PlastrougiTutor: Ylva EkströmCourse: Media and Communication Studies CPeriod: Fall 2007University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: My main purpose with this paper is 1) to study how film as a media can subvert traditional gender constructions and 2) study the character of Elizabeth Swann in the trilogy Pirates of the Caribbean through four dimensions; Gender performance, Class, Desire and Power.Material/Method: My main material is the trilogy Pirates of the Caribbean. I have studied Elizabeth?s character based on semiotic and narratological methods.Main results: Film as a media possesses the full potential to change traditional gender roles, but the full subversion is denied due to the heterosexual matrix. Elizabeth?s character almost completes her subversive journey throughout the trilogy, but since she too is a victim of the heterosexual matrix, a full subversion is not possible.Key words: gender performance, class, desire, power, sex/gender, subversion, narratologic, semiotic, queer, feminism, pirates of the caribbean, intersectionality, parody.
