Sex timmars arbetsdag, varför inte? : En studie om förkortad arbetstid / Six hour workday, why not? : A study about shorther working hours

Bredhammar, Andreas, Helander, Stefan, Svensson, Moa January 2019 (has links)
Forskningsfråga: Vilka problem försvårar möjligheten att införa en kortare arbetsvecka? Syfte: Syftet med studien är att identifiera problem som mellanchefer förutsätter försvårar möjligheten att införa kortare arbetsvecka Metod: Studien är genomförd utifrån en kvalitativ forskningsmetod med en induktiv ansats. Det empiriska materialet består av sju stycken interjuver med mellanchefer i olika organisationer. Slutsatser: De kategorier vi har identifierat ligga till grund för problem är gemenskap och tillhörighet, normer,legitimitet, styrning, produktivitet och teknologi, kostnader samt hälsoaspekter. De vi har funnit är de alla hör samman och påverkar varandra och skapar ett problem för införandet av förkortad arbetsvecka. Mellanchefens komplexa situation är också en faktor för att det upplevs som problematiskt att införa förkortad arbetsvecka. / Research question: What problems limit the possibility to implement shorter working weeks? Purpose: The purpose with the study is to identify problems that the head of the department presume limit the possibility to implement a shorter working week. Method: The study is conducted on the basis of a qualitative research method with an inductive approach. The empirical content consisted of seven different interviews with the head of the department of their organization. Conclusions: Problems have been found to occur within the different categories community and belonging, standards, legitimacy, management, productivity and technology, costs and health aspects. We have found out that all of these affect each other and create problems when it comes to implementation of shorter working weeks. The head of department have shown to be a complex role to handle and has also been perceived as a contributing factor to why an implementation of shorter working weeks is so problematic.

UTILIZATION OF WIND POWER IN RWANDA : Design and Production Option

Eric, MANIRAGUHA January 2013 (has links)
This Master Thesis is the research done in the country of Rwanda. The project leads to study the climate of this country in order to establish whether this climate could be used to produce energy from air and to implement the first wind turbine for serving the nation.   After an introduction about the historical background of wind power, the thesis work deals with assessment of wind energy potential of Rwanda in focusing of the most suitable place for wind power plants. The best location with annual mean wind speed, the rate of use of turbine with hub height for an annual production per year, the mean wind speeds for 6 sites of Rwanda based on ECMWF for climatic data for one year at relief of altitude of 100m and coordinates are reported too.   The result of energy produced and calculations were done based on power hitting wind turbine generator in order to calculate Kinetic energy and power available at the best location to the measurement over the period of 12 months, that could be hoped for long term.   With help of logarithmic law, where wind speed usually increases with increasing in elevation and the desired wind speeds at all 6 sites were used. The annual energy production was taken into account at the best site with desired wind speed at the initial cost of turbine as well as the cost of energy (COE).However, with comparison of the tariff of EWSA, the price of Wind designed in this Research per kWh is cheaper and suitable for people of Rwanda. / <p><em>Rwanda has considerable opportunities development energy from hydro sources, methane gas, solar and peat deposits. Most of these energy sources have not been fully exploited, such as solar, wind and geothermal. As such wood is still being the major source of energy for 94 per cent of the population and imported petroleum products consume more than 40 per cent of foreign exchange. Energy is a key component of the Rwandan economy. It is thus recognized that the current inadequate and expensive energy supply constitutes a limiting factor to sustainable development. Rwanda’s Vision 2020 emphasizes the need for economic growth, private investment and economic transformation supported by a reliable and affordable energy supply as a key factor for the development process. To achieve this transformation, the country will need to increase energy production and diversify into alternative energy sources. Rwandan nations don’t have small-scale solar, wind, and geothermal devices in operation providing energy to urban and rural areas. These types of energy production are especially useful in remote locations because of the excessive cost of transporting electricity from large-scale power plants. The application of renewable energy technology has the potential to alleviate many of the problems that face the people of Rwanda every day, especially if done so in a sustainable manner that prioritizes human rights.</em></p>
