Dependence between renewable energy related critical metal futures and producer equity markets across varying market conditions

2022

We study the dependence of renewable energy production-related critical metal futures and producer equity returns, compared to the non-renewable energy (oil and natural gas) and some other globally relevant commodity markets. We find different asymmetric and symmetric dependencies in these commodity markets. The dependence is asymmetric in the most important critical metal markets, i.e., of silver, copper, and platinum. Still, surprisingly, for example, in the oil market, the relationship is symmetric, and no relationship is found in the natural gas market. Furthermore, the oil and agricultural markets have homogenous dependence structures in most market conditions, so the information trans…

Understanding the scaling-up of community energy niches through Strategic Niche Management Theory: insights from Finland

2018

The growing phenomenon of civil society involvement in renewable energy generation has attracted researchers’ interest. However, rather little is known of how a diverse and relatively small sector such as community energy could scale up and promote a change in energy production. We examine this issue through the lens of Strategic Niche Management (SNM) and conceptualize community energy as a socio-technical niche that holds the potential to promote a transition to renewable energy. Drawing on interview data with members of community energy projects and experts in Finland, we identify different types of community energy projects and the factors that may prevent them from scaling up. The stud…

"Ku talvella ei paista aurinko ni pittää syyä salaattia ni siitä saa vitamiineja": 5. ja 9. luokkalaisten ruokatottumukset, ruokavalinnat ja tiedonlä…

2016

Koljonen, Eveliina. 2016. ”Ku talvella ei paista aurinko ni pittää syyä salaattia ni siitä saa vitamiineja”. 5. ja 9. luokkalaisten ruokatottumukset, ruokavalinnat ja tiedonlähteet. Kasvatustieteen ja terveystiedon pro gradu -tutkielma. Jyväskylän yliopisto. Kasvatustieteiden laitos. Terveystieteiden laitos. 109 sivua. Tämä tutkimuksen tarkoituksena oli kuvata yleisesti nuorten ruokatottumuksia sekä vertailla 5. ja 9. luokkalaisten sekä tyttöjen ja poikien välisiä eroja. Lisäksi tutkimus pyrki selvittämään, millaisia asioita nuoret kokevat merkityksellisiksi ruokavalinnoissaan, mitä lähteitä nuoret käyttävät etsiessään tietoa ravitsemuksesta sekä pitävätkö he käyttämiään lähteitä luotettavi…

Prospects for advanced electron cyclotron resonance and electron beam ion source charge breeding methods for EURISOL

2011

International audience; As the most ambitious concept of isotope separation on line (ISOL) facility, EURISOL aims at producing unprecedented intensities of post-accelerated radioactive isotopes. Charge breeding, which transforms the charge state of radioactive beams from 1+ to an n+ charge state prior to postacceleration, is a key technology which has to overcome the following challenges: high charge states for high energies, efficiency, rapidity and purity. On the roadmap to EURISOL, a dedicated R&D is being undertaken to push forward the frontiers of the present state-of-the-art techniques which use either electron cyclotron resonance or electron beam ion sources. We describe here the gui…

Potential applications of nanotechnology in bioenergy

2011

Nanotechnology has an increasingly large impact on a wide range of industries, but its current use in the production of electricity and heat from biomass is limited. This thesis examined the potential impact of nanotechnology on bioenergy production through a literature review and interviews with industry members. Current technologies and methods in use were reviewed, with a focus on fuel handling and combustion systems. Areas in which problems existed were identified and nanotechnologies with properties relevant to those problems examined. The major nanotechnology areas which were reviewed are nanostructured coatings (wear resistant, corrosion resistant, low friction and anti-icing), nanom…

Parliamentary sources in the comparative study of conceptual history: methodological aspects and illustrations of a research proposal

2009

Summary: This article proposes that historians and political theorists should exploit parliamentary sources to move from the writing of national histories to the comparative study of the conceptual history of European political cultures. Complementing the German lexicographical approach to conceptual history, the authors argue that parliamentary debates in several European countries provide more reliable sources for the past use of the language of politics. They emphasize the possibilities for the study of political history and the rhetoric of parliamentary institutions offered by the use of parliamentary debates side by side with the study of archival sources and published literature. Rhet…

Analysis of network rumor dissemination and control mechanisms on Chinese social network : Sina Weibo

2016

The social network has become a major source of information. The openness and swiftness of the network bring instant accessing to both true and false information. Sometimes the false information such as network rumors can mislead people from obtaining the true information and even create chaos. The social network platforms and the governments in different countries are making effort on enacting their own mechanisms to strive on eliminating the rumors. The aim of this thesis is to investigate the spreading of rumors on the Chinese social networking website Sina Weibo. The censorship policy of the Chinese government and the methods used to control the spreading of rumors are discussed. The la…

Bioenergian potentiaalitarkastelu Pirkanmaan alueelta - energiaomavaraisuuden jäljillä

2011

Energiaomavaraisuuteen ei Suomessa ole juurikaan kiinnitetty huomiota edullisen tuontienergian aikana. Kuitenkin useat kansainväliset tahot painottavat tarvetta siirtyä kohti energiaomavaraisempaa ja hajautetumpaa energiantuotannon rakennetta. Suomen uusiutuvat energiavarat ovat monipuoliset, ja niiden avulla energiaomavaraisuutta olisi mahdollista parantaa merkittävästi. Tämän pro gradun tarkoituksena oli tarkastella energiaomavaraisuuden tilaa Pirkanmaalta valittujen maaseutuvaltaisten kuntien kautta. Työssä selvitettiin tarkastelualueen tämän hetkinen energiantuotannon infrastruktuuri sekä energiantuotannon ja -kulutuksen rakenteita suhteessa paikallisiin bioenergiavaroihin. Bioenergian …
