”Du sköna sång, vårt bästa arv” - kanonisering av en sångskatt ur ett hermeneutiskt perspektiv

Songs have the power to get through to people. When lyrics are combined with a tune, the result is an entity where the first few notes of a melody can evoke emotions of recognition and belonging. A song treasury consists of such songs that are part of a canonized song tradition. The process where certain songs become part of an established song treasury is long, and many other aspects than the tune itself influence the forming of a song treasury. By examining the characteristics of a song tradition, the history of an ethnic group can be illuminated. In this study, music, pedagogy, and the sociocultural context are merged into a whole where a common song tradition, the song treasury, is in focus. The main aim of this study is to deepen the understanding of a song treasury, its development and contents. This understanding is accomplished by analyzing the musical and lyrical characteristics of 60 songs, which have been sung in schools, homes, and communities, thereby becoming popular among the Swedish-speaking Finns during the 20th century. The songs have been chosen by combining three song lists, of which two lists are closely related to school curricula. The third song list is a result of a survey on favourite songs, according to the situation around year 2000. The songs are examined in their notated versions, a number of song books and text books (n = 29) forming the empirical material. In this study, a hermeneutical approach is applied, content analysis being the method. The analysis is based on three perspectives: the sociocultural perspective, the music-pedagogical perspective, and the musico-analytical perspective. Within each perspective, two aspects are studied. This results in a hexagonal model which forms the structure of the study as a whole. The first two perspectives form the background; a historical context where nation, education, home country, and homestead are regarded as highly important. A common song repertoire is considered to be an effective means of building collective identity within ethnic groups, the common language and the cultural heritage being used as rhetorical arguments. During the early 1900s, choir festivals become an educational platform where conceptions of a common belonging are developed and strengthened through religious, patriotic, and poetical expressions. National school curricula in singing and music have similar characteristics, cultural heritage and values education being in focus. The song lyrics often describe nature and emotions, and they also appear to be personal and situated in a given time and place. Patriotic expressions and songs about music are also fairly common. The songs generally express positive attitudes, which are intensified by major tonality, rich and varied melodies with stable rhythms, and a strong tonal base. The analyzed details of the studied aspects are merged into a thick description, which results in an interpretation pattern with three dimensions: a song treasury can be considered an expression of collective identity, cultural heritage, and values education.

Improving internal performance of a company - Introducing employee empowerment via job redesign in Finnish small and medium sized enterprises

This bachelor's thesis is about to find out to what extent Finnish managers and small and medium sized organizations are willing and able to put employee empowerment into practice and what experiences they have got from employee empowerment as an approach towards job redesign. Some of the top enterprises in the world are known for their empowered employees as a single most important factor for their success and this thesis focuses on introducing the subject to Finnish managers and organizations to find out what benefits, barriers and other thoughts they have about the whole idea of empowered employees in Finnish organization culture. Most notable findings in this thesis are that Finnish managers do think that their organization's employees are capable to work efficiently if their job is extended and the organizations would perform better when right person's job is enriched and he/she is given more power to solve problems.

POP UP & LEAN START UP - yrittäjyyden opetusmallin kehittämishanke toisen asteen koulutuksessa

Tutkimuksen tavoitteena oli tarkastella ammatillisen koulutuksen yrittäjyyskasvatuksen käytännön opetuksen toteutusmahdollisuuksia. Tarkasteluun vaikuttaa vuonna 2015 voimaan astuva ammatillisen perusopetuksen opetussuunnitelmauudistus. Käytännön opetuksen toteutuksen viitekehykseksi valittiin synteesi pop up ja lean startup liiketoimintamallien viitekehyksistä. Tutkimuksen kohteena olivat viralliset opetussuunnitelmauudistuksen asiakirjat ja liiketoimintamalleja käsittelevä kirjallisuus. Tutkimusmenetelmänä käytettiin integoivaa narratiivista kirjallisuusanalyysiä. Aineiston analyysissä käytettiin Atlas-ti ohjelmistoa. Tutkimuksen tuloksena muodostui kuva työelämälähtöisistä uudistuvista opetussuunnitelmista, missä yrittäjyyskasvatuksen rakenteet eivät todellisuudessa muutu entisestä merkittävästi. Sen sijaan, uutta tulevat olemaan opetuksen toteutukselle asetetut haasteet: yksilöllistetyt opintopolut ja opiskelumallien monipuolistamisen merkittävä kasvu. Yrittäjyyskasvatukselle asetetaan Suomessa yhteiskunnallisesti korkeita tavoitteita. Se, miten niihin päästään ja millaisella pedagogiikalla, jää eri ammatillisten oppilaitosten ratkaistavaksi paikallisesti. Pop up ja lean startup liiketoimintamallit tarjoavat tulevaisuuden kannalta merkittäviä mahdollisuuksia yrittäjyyden käytännön opetuksen viitekehyksiksi. Lisäksi ne sopivat nopeatempoiseen ja ajallisesti tiukkarajaiseen opetuksen viitekehykseen hyvin uudenaikaisina asiakaslähtöisinä innovaatio- ja liiketoimintamalleina.

Loistehon säätö ja kompensointi

Kantaverkkoyhtiö Fingrid Oy on tarkastellut kantaverkosta otettua tai tuotettua loistehoa alueittain Fingridin määrittelemällä maantieteellisellä tavalla. Alue koostuu liittymispisteistä, jotka ovat yksittäisten verkkoyhtiöiden liittymispisteitä. Yhden alueen sisällä voi siis olla monia eri verkkoyhtiöiden liittymispisteitä. Vuodesta 2016 alkaen loistehon tarkastelu vaihtuu aluetarkastelusta liittymispistetarkasteluun. Liittymispistetarkasteluun siirtymisen myötä tulee verkkoyhtiöiden investoida erinäisiin kompensointiratkaisuihin, jotta yksittäisten liittymispisteiden loistehot pysyvät Fingridin asettaman loistehon tarkasteluikkunan sisällä. Työssä perehdytään erinäisiin kompensointiratkaisuihin ja niiden kytkentöihin sekä kytkentöjen vaikutuksiin olemassa olevaan sähköverkkoon. Lisäksi työssä käsitellään tuulivoimaloiden hyödyntämistä loistehon säädössä. Esimerkkitapauksessa tarkastellaan erästä Caruna Oy:n verkkoa ja pohditaan teknistä ja mahdollisimman taloudellista kompensointiratkaisua kyseiseen verkkoon. Työn lopputulos on, että maakaapeloinnin määrän kasvaessa loistehon kompensoinnin tarve kasvaa. Näin ollen Fingrid Oy:ltä tarvitaan selkeitä linjauksia moneen ongelmakohtaan, kuten tuotanto-kulutuspisteen loistehon tarkasteluun. Lisäksi Energiavirastolta tarvitaan kannusteita loistehon kompensointiin, sillä verkkoyhtiöiden liiketoiminta perustuu regulaatiomalliin ja kompensointilaitteiston yksikköhinnasto on hyvin suppea.

Medborgare, brukare av välfärd eller klient? : en jämförande studie om brukarens inflytande mellan en kommun, ett assistansbolag och ett brukarkooperativ som utför personlig assistans

The focus of this licentiate dissertation is to produce a better understanding of how we may give citi-zen as users a stronger influence over their welfare services and in the long run help to democratize the welfare state. The aim of this project is to analyze what kind of influence a user with a functional dis-order may have in different organizational contexts over his or her personal assistance. This study focuses on the influence a user may have over his or her welfare service, personal assis-tance. A municipality, an assistance firm and a user cooperative are compared with the thesis that the organization that surrounds the users shapes the possibilities the user have to influence his or her per-sonal assistance. The major thesis is thus: Participatory democracy as a model or approach may function differently when the services are delivered in a different way by different organizations – varying organizational forms. There are questions that try to answer if there are outspoken social goals within each organization. Questions regarding influence of the user when she or he is choosing the assistance provider and the users possibility to influence and his or her power to decide who and when anyone works as an assis-tant are asked. The results indicate that there are different sets of internal logic within the organizations that affect their goals and level of user influence. Within the user cooperative the user is considered a citizen and as a user expected to handle the role as work leader for his or her personal assistants. However the user is also a citizen and is expected within the usercooperative to act as a member and citizen to have po-litical influence. The usercooperative aims at influencing the political policy process regarding ques-tions concerning the rights of persons with disabilities. This gives the user a part in collective action as a member of the usercooperative. The other producers of personal assistance, the municipality and the assistance firm gives in this study a similar result as they give the user of personal assistance quite similar models for user influence within the respective organization. Within these organizations the user have chosen to let the organiza-tions handle the role of work leader in the written agreements with the producer and thereby the influ-ence they may have in practice is not so much a case of self-determination as a case of co-influence. The user can be seen as a user within a municipality, a client or consumer within the assistance firm and a citizen within the usercooperative. The results indicate the need for future research where co-production, institutional logic and development of democratic theory through democratic innovations are central aspects of future research.

Review of water electrolysis technologies and design of renewable hydrogen production systems

An electric system based on renewable energy faces challenges concerning the storage and utilization of energy due to the intermittent and seasonal nature of renewable energy sources. Wind and solar photovoltaic power productions are variable and difficult to predict, and thus electricity storage will be needed in the case of basic power production. Hydrogen’s energetic potential lies in its ability and versatility to store chemical energy, to serve as an energy carrier and as feedstock for various industries. Hydrogen is also used e.g. in the production of biofuels. The amount of energy produced during hydrogen combustion is higher than any other fuel’s on a mass basis with a higher-heating-value of 39.4 kWh/kg. However, even though hydrogen is the most abundant element in the universe, on Earth most hydrogen exists in molecular forms such as water. Therefore, hydrogen must be produced and there are various methods to do so. Today, the majority hydrogen comes from fossil fuels, mainly from steam methane reforming, and only about 4 % of global hydrogen comes from water electrolysis. Combination of electrolytic production of hydrogen from water and supply of renewable energy is attracting more interest due to the sustainability and the increased flexibility of the resulting energy system. The preferred option for intermittent hydrogen storage is pressurization in tanks since at ambient conditions the volumetric energy density of hydrogen is low, and pressurized tanks are efficient and affordable when the cycling rate is high. Pressurized hydrogen enables energy storage in larger capacities compared to battery technologies and additionally the energy can be stored for longer periods of time, on a time scale of months. In this thesis, the thermodynamics and electrochemistry associated with water electrolysis are described. The main water electrolysis technologies are presented with state-of-the-art specifications. Finally, a Power-to-Hydrogen infrastructure design for Lappeenranta University of Technology is presented. Laboratory setup for water electrolysis is specified and factors affecting its commissioning in Finland are presented.

Crowdfunding as a new funding alternative for early stage start-ups

Attracting outside capital is a common problem for start-up companies. Capital markets define the funding options for companies and firms which suffer the most from these capital market imperfections are small start-up companies. Therefore it is important to study any new funding model which can offer a new solution to this inefficiency of capital markets. This study explains the traditional funding models for start-ups such as founders, friends & family, banks, business angels and venture capitalist. After giving background to traditional start-up funding this study delves into crowfunding (CF) and introduces it as a new funding method. The objective of the thesis is to answer one broad research question: Why and how should start-up companies use CF as an alternative funding method? To properly delve into this, this question has the following sub-questions: What kind of funding alternatives do start-up companies have? What are the pros and cons of CF compared to other funding options? How can start-ups benefit from CF? This study gives background on the rise of CF and the reasons why this new model is needed. Author will explain the different components of CF such as platforms, crowdfunders and projects. Also benefits and challenges of the crowdfunding model are investigated. As a new funding model CF has had to clear out many obstacles from its way. These are, for example, legal and regulatory issues as well education of crowd investors to understand this new investment option. . Start-up entrepreneurs can gain valuable insight from this study. The author has attempted to form best practices and guidelines of how to operate in the CF environment. This study was conducted by performing expert interviews, collecting data from previous studies and performing a content analysis of successful crowdfunding cases. Main findings from the study were that CF has huge potential in funding entrepreneurial projects. It is still a niche way for funding but growing rapidly. CF is earning its place among traditional funding options and has potential to fund projects which otherwise would struggle to find funding. With CF entrepreneur can tap into geographically diverse audience. It is a powerful validation tool for products and ideas and has the power to bring democratic elements to entrepreneurial funding.

Narrative transportation in global brand content

People understand life and events around them through narratives. Narratives are a new way for marketers to convey messages to consumers about their brands and products. Brand narratives are an effective way to reach out to people due to their influential nature. Narratives have a power to change beliefs and attitudes, making them relevant and interesting for any marketer. The power of narratives has to do with narrative transportation, which narratives can trigger in people. A transported person is more likely to perceive brand or product in a more positive light. The creators of the narrative are able to influence the content of the narrative through message factors that work as antecedents for narrative transportation. This study explored narrative transportation qualities of well established advertisements. The study uses qualitative content analysis to analyze and identify narrative transportation antecedents among Cannes Lion grand prix winners in the film category between years 2005 to 2015 (15 in total). The narrative transportation antecedents are identifiable characters, imaginable plot and verisimilitude, which were used in the analysis of the data. The study analyzes the winners to make judgment on whether they can trigger narrative transportation or not. It was found that the Cannes Lion grand prix winner advertisement mostly had identifiable narratives in them. In most of the advertisement (ten out of fifteen) at least two out of three antecedents were found, thus most of them are able to trigger narrative transportation. The study also found that most narratives in the advertisement were able to be linked to the main brand narrative of the advertiser. In four of the advertisements the link to the brand narrative was not able to be established. The study concludes by discussing certain factors and aspects of the advertisements that were identified to further enhance the narrative transportation qualities of the advertisement.

Liquid-phase alcohol promoted methanol synthesis from CO2 and H2

Methanol is an important and versatile compound with various uses as a fuel and a feedstock chemical. Methanol is also a potential chemical energy carrier. Due to the fluctuating nature of renewable energy sources such as wind or solar, storage of energy is required to balance the varying supply and demand. Excess electrical energy generated at peak periods can be stored by using the energy in the production of chemical compounds. The conventional industrial production of methanol is based on the gas-phase synthesis from synthesis gas generated from fossil sources, primarily natural gas. Methanol can also be produced by hydrogenation of CO2. The production of methanol from CO2 captured from emission sources or even directly from the atmosphere would allow sustainable production based on a nearly limitless carbon source, while helping to reduce the increasing CO2 concentration in the atmosphere. Hydrogen for synthesis can be produced by electrolysis of water utilizing renewable electricity. A new liquid-phase methanol synthesis process has been proposed. In this process, a conventional methanol synthesis catalyst is mixed in suspension with a liquid alcohol solvent. The alcohol acts as a catalytic solvent by enabling a new reaction route, potentially allowing the synthesis of methanol at lower temperatures and pressures compared to conventional processes. For this thesis, the alcohol promoted liquid phase methanol synthesis process was tested at laboratory scale. Batch and semibatch reaction experiments were performed in an autoclave reactor, using a conventional Cu/ZnO catalyst and ethanol and 2-butanol as the alcoholic solvents. Experiments were performed at the pressure range of 30-60 bar and at temperatures of 160-200 °C. The productivity of methanol was found to increase with increasing pressure and temperature. In the studied process conditions a maximum volumetric productivity of 1.9 g of methanol per liter of solvent per hour was obtained, while the maximum catalyst specific productivity was found to be 40.2 g of methanol per kg of catalyst per hour. The productivity values are low compared to both industrial synthesis and to gas-phase synthesis from CO2. However, the reaction temperatures and pressures employed were lower compared to gas-phase processes. While the productivity is not high enough for large-scale industrial operation, the milder reaction conditions and simple operation could prove useful for small-scale operations. Finally, a preliminary design for an alcohol promoted, liquid-phase methanol synthesis process was created using the data obtained from the experiments. The demonstration scale process was scaled to an electrolyzer unit producing 1 Nm3 of hydrogen per hour. This Master’s thesis is closely connected to LUT REFLEX-platform.

Mitigation possibilities to Greenhouse gas emissions from power production in India

Global warming is assertively the greatest environmental challenge for humans of 21st century. It is primarily caused by the anthropogenic greenhouse gas (GHG) that trap heat in the atmosphere. Because of which, the GHG emission mitigation, globally, is a critical issue in the political agenda of all high-profile nations. India, like other developing countries, is facing this threat of climate change while dealing with the challenge of sustaining its rapid economic growth. India’s economy is closely connected to its natural resource base and climate sensitive sectors like water, agriculture and forestry. Due to Climate change the quality and distribution of India’s natural resources may transform and lead to adverse effects on livelihood of its people. Therefore, India is expected to face a major threat due to the projected climate change. This study proposes possible solutions for GHG emission mitigation that are specific to the power sector of India. The methods discussed here will take Indian power sector from present coal dominant ideology to a system, centered with renewable energy sources. The study further proposes a future scenario for 2050, based on the present Indian government policies and global energy technologies advancements.

Sustainable Waste-to-Energy Production: Performance Evaluation of Distributed Generation fuelled by Landfill Gas

The environmental impact of landfill is a growing concern in waste management practices. Thus, assessing the effectiveness of the solutions implemented to alter the issue is of importance. The objectives of the study were to provide an insight of landfill advantages, and to consolidate landfill gas importance among others alternative fuels. Finally, a case study examining the performances of energy production from a land disposal at Ylivieska was carried out to ascertain the viability of waste to energy project. Both qualitative and quantitative methods were applied. The study was conducted in two parts; the first was the review of literatures focused on landfill gas developments. Specific considerations were the conception of mechanism governing the variability of gas production and the investigation of mathematical models often used in landfill gas modeling. Furthermore, the analysis of two main distributed generation technologies used to generate energy from landfill was carried out. The review of literature revealed a high influence of waste segregation and high level of moisture content for waste stabilization process. It was found that the enhancement in accuracy for forecasting gas rate generation can be done with both mathematical modeling and field test measurements. The result of the case study mainly indicated the close dependence of the power output with the landfill gas quality and the fuel inlet pressure.

Promoting Growth in the Use of Bioenergy in Europe by Converting Existing Coal-Fired Power Plants to Biomass

Repowering existing power plants by replacing coal with biomass might offer an interesting option to ease the transition from fossil fuels to renewable energy sources and promote a fur-ther expansion of bioenergy in Europe, on account of the potential to decrease greenhouse gas emissions, as well as other pollutants (SOx, NOx, etcetera). In addition, a great part of the appeal of repowering projects comes from the opportunity to reuse the vast existing invest-ment and infrastructure associated with coal-based power generation. Even so, only a limited number of experiences with repowering are found. Therefore, efforts are required to produce technical and scientific evidence to determine whether said technology might be considered feasible for its adoption within European conditions. A detailed evaluation of the technical and economic aspects of this technology constitutes a powerful tool for decision makers to define the energy future for Europe. To better illustrate this concept, a case study is analyzed. A Slovakian pulverized coal plant was used as the basis for determining the effects on perfor-mance, operation, maintenance and cost when fuel is shifted to biomass. It was found that biomass fuel properties play a crucial role in plant repowering. Furthermore, results demon-strate that this technology offers renewable energy with low pollutant emissions at the cost of reduced capacity, relatively high levelized cost of electricity and sometimes, a maintenance-intensive operation. Lastly, regardless of the fact that existing equipment can be reutilized for the most part, extensive additions/modifications may be required to ensure a safe operation and an acceptable performance.
