Vem får höras? : En undersökning av lokalpress kring makt och kön i fyra Landsortstidningar

2 (45)AbstractAuthors: Gunnel Forssell Ehrlich & Alexandra WinbergTitle: Gender in local press ? a quantitative study of four local newspapers Level: BA Thesis in Media and Communication StudiesLocation: Linnaeus UniversityLanguage: SwedishNumber of pages: 50The report shows a quantitative study of balance in gender and position of power in the local press. The study aimed to shed light on the distribution of space in the newspaper between men and women, those within power and those without in Swedish local press. The study was conducted with four newspapers, during a month of time with local editorial news material. In our study, we have assumed Lippmann?s and Strömbäck?s theories of pseudo-reality and distribution of gender and position of power in Sahlstrand and Jarlbro.

Ny stamstation i Yttermalung för anslutning av vindkraft : Nätstudie av olika utföranden i normal- och reservdrift

Since 2004, wind power has had the largest installation of new capacity compared to other energy sources in Sweden. Accommodating new wind power may require strengthening or rebuilding of the existing grid in areas where the grid is already loaded to maximum capacity. This master thesis examine the possibility of a new 400/130 kV substation in Yttermalung, Sweden, with a connection to the two neighboring regional grids in Dalarna and Värmland owned by Fortum. This substation would provide a new connection point to the Swedish transmission system as well as an interconnection of the two, currently separated, regional grids. Different expansion scenarios where a substation with and without series compensation or a phase shifting transformer (PST) to control active power flow were studied.

Wobblerpump

The task was to design and manufacture a submersible displacement pump working with the wobble plate principle. The main task for the Wobble plate pump is to be used as a sewage pump for smaller households or dewatering pump in environments where small flows and high pressures are acquired. For these purposes ITT Flygt sell a screw pump, PC-Grinder 3068. The hydraulic part of the PC-Grinder is manufactured by a subcontractor. Therefore ITT Flygt wants to evaluate an alternative to their screwpump PC-Grinder, which can be entirely manufactured by them self.

VINDKRAFTSETABLERINGAR : EN JÄMFÖRANDE STUDIE OM NÄRBOENDES INSTÄLLNING TILL VINDKRAFT OCH VINDKRAFTSETABLERINGAR I SVERIGE OCH BRASILIEN

To achieve a sustainable development, three aspects have to take equal place in the society; environmental, economical and social. To reduce the impact on the environment and the amount of greenhouse gases supplied to the atmosphere, industrialized countries and less developed countries must start cooperating. Also the use of renewable energy sources, like solar, hydro and wind power, have to increase.Wind power has great potential as a future energy supply. It is cost efficient, quickly developed and the resource is abundant and available worldwide.Examinations made in Sweden, indicates that there are difficulties establishing wind power at the same pace as the environmental goals, set by the Swedish government, requires. Mainly because people living nearby potential areas for wind power farms, appeal against the decision.This study aims to investigate differences between how people in Sweden and Brazil look at wind power as a future energy source and at the establishing process.

Offentlig konst och offentlig makt

The main purpose of the culture is to serve people and represent the people's social will and freedom. Culture does not exist in a vacuum but shaped and framed by political and artistic structures that are not neutral, and this is why the artwork itself cannot be an independent business. The public function of art can be understood as a defense of the ideals of democracy. But today, when political power is often replaced by hegemony, the role of art and functions are changing. How these changes reflect to the identity, reality and truth of society? What political functions are fulfilled when art becomes ?public?? The issue of democracy is linked question of people?s power in a democratic society where power is legitimized in social space.

Trossamfundens makt i Sverige : En uppsats om stat-kyrka reformen och dess inverkan på trossamfundens maktposition

The aim of this paper is to describe and explain how the separation between state and church effects the power relations between state and religious groups and organizations. Former state church, The Swedish church, is in this paper, not included in the definition of religious groups. The reform (?stat-kyrka reformen?) took place between 1995 and year 2000.I?m examining if religious groups had any influence on the reform. My expectation is to give a clearer picture of religious groups and its power position in Swedish politics and society.

Medier, makt och rasism : En kritisk diskursanalys av svenska nyhetsmediers rapportering om Rinkeby

The aim of this thesis is to examine expressions of power and racism in news reporting about the district of Rinkeby, Sweden, in two major Swedish newspapers. News articles are examined using Norman Fairclough?s three-dimensional model for critical discourse analysis. The discourse theory has also been complemented with theories of media in relation to power, ideology and racism. The study has shown that news reporting about Rinkeby largely focused on stereotypical subjects such as violence, social problems and crime.

Lantbrukares möjlighet till en investering i solceller

When the costs for a company increase it is normal to look for alternatives to lower thesecosts. One of the expenditure that farmers have is energy costs. The price for the energy mayvary because of the free market. To look at the possibilities for a farmer to invest in sunpower, to make the company less sensitive for the changes on the electrical market, isinteresting. The biggest part of the electricity that is produced in Sweden comes from a fewcompanies on the market.

EN FALLSTUDIE OM URBAN VINDKRAFT VID ALBANO

The use of energy is an important question in today´s society, and a substantial part of the energy that is used today is used in our homes. To lower this usage is vital, and there are regulations in place both on the national and the local level, that say that new apartment blocks must be built to consume less energy, which in the end will lower the impact on the climate.One way to make the housing sector more environmentally sustainable, is to produce energy issions that are bad for the environment, for example to build wind turbines close to or even on the buildings, so called urban wind power. The scope for this report is to see if urban wind power could be a sustainable alternative for the residential area that Svenska Bostäder plans to build in Albano in Stockholm.There are extensive scientific theories regarding wind and wind power, and a literature study is made to investigate past knowledge in the area. Efforts have been made to find earlier trials with urban wind power and, both scientific research and trials where urban wind power actually has been installed. The theory chapter deals both with the wind itself and how electricity can be generated from wind.

Vattenrådens roll i vattenförvaltningen : Ett myndighetsperspektiv på lokalt deltagande

The purpose of this essay is to illustrate how the position of power / exercise of power are perceived in today's schools from the teacher's perspective. I have examined how students' freedom and democracy education interpreted in real life, and how this affects both teacher and student learning approaches. I would also highlight the need to set standards for children's psychological development related to the consequences will be. I have chosen to perform a qualitative research through individual interviews with five participating teachers from different experiences in different type of school. I have used the hermeneutic method of analysis to analyze the material.

Undersökning av ögats brytningsförmåga i ett svenskt hästmaterial :

Skiascopy, also called retinoscopy, is a method for determining the refractive power of the eye. There are only a few, old studies made on equine refraction. The aim of this study was to investigate the refractive power in a population of Swedish horses. The study consists of a review of relevant studies done on animals and an experimental part where the refractive power of 93 horses of different age, breed and usage was examined. A pilot study of 12 horses was performed regarding the importance of cycloplegia when doing skiascopy on horses. The results of the pilot study show no significant difference in the skiascopy results between the group before and after cycloplegia were induced. Consequently, there is no need of inducing cycloplegia before doing skiascopy in adult horses. The study shows that horses usually were emmetropic (normally sighted) with minor deviations toward myopia or hyperopia.

Strategi för utvecklande av reglerbudata

This Master Thesis discusses the development of bids for regulation power with consideration of change of discharge. The study was initiated by Vattenfall PD and is a limited part of a substantial development project at the same division. The background of the project is the new demands from SvK, which among other things includes more detailed regulation bids. As from the 1st of November 2008, the regulation bids are supposed to be calculated regarding each specific regulation object, something that is defined by SvK. These new demands changes Vattenfall?s conditions and will increase the need for detailed knowledge about available regulation power and costs for regulation.In this study a strategy for regulation bids was developed.

Hur påverkar en ökad andel solceller Umeå Energis elnät? : ? En utredning med fokus på spänningsvariationer och osymmetri inom landsbygds- och tätortsnät vid en- och trefasanslutning av solcellsanläggningar

A good power quality can be an important prerequisite to achieve a sustainable society. Scandinavia's electrical system is in many respects superior, and Sweden has a fossil free electricity generation at 97 % and a reliability of electricity distribution at 99.98 %. Meanwhile, the EU has an ambition to expand the electricity market in order to achieve a joint trading business across Europe. This cross-border market will result in a large proportion of fossil energy sources integrated into our electrical system, which also leads to an increased need for renewable electricity production in Sweden. One part of this development is to increase the share of renewable micro generation that is locally or regionally connected to the power grid.

Elektrifiering av jordbruksmaskin : Direktkoppling till solföljare och elnät

The agricultural sector is currently highly dependent on fossil fuels, with diesel beingmost prominent. There are however both historical and modern alternatives thathave not been subject to enough evaluation to disregard them as suitable alternative.This report aims to theoretically investigate the feasibility of converting aconventional diesel driven tractor to run on electricity, delivered via a cableconnected to either the main power grid or on-site electric production, such asphotovoltaic. Delivering electricity to the machine via a cable is a method withhistorical roots in the early 20th century and in the present day mining industry.The economic and technological potential of the technique are evaluated, along withthe examination of several different motor powers, voltages, losses and constructionideas. The report finds the technique to be both possible as well as long termeconomically and environmentally beneficial. To realise this method however, somedeviations from the present methods of agricultural farming must be made,considering the more advanced driving patterns, the limited mobility and therequirement for extra driver awareness.

Bilden som kommunikationsverktyg

Transportation of pigs might be a welfare problem. Stress during and after transportation can negatively affect the meat quality or cause carcass damages, which leads to major economic losses every year. The transportation chain can be divided into several stages; loading, transport and unloading. This literature review focuses on unloading of pigs from a transport. When arriving at an abattoir pigs can be fatigued and need to be as smoothly unloaded as possible.
