Tailoring of the solid state properties of Al-Nb mixed oxides: A photoelectrochemical study
2013
Al-Nb containing mixed oxides were grown by anodizing sputter-deposited Al-Nb alloys of different compositions. A photoelectrochemical investigation was carried out in order to estimate the band gap, flat band potential, and conductivity type of these oxides as a function of their composition. The dependence of the band gap on the composition of mixed sp-d metal oxides has been rationalized by using a semiempirical correlation between the difference of electronegativity and band gap of oxides proposed in the literature some years ago and recently tested for regular d-d metal mixed oxides. The band gap increase observed as a function of Al content into the oxides seems mainly depending on th…
Bi-2212 and Y123 highly curved single-crystal-like objects: whiskers, bows and ring-like structures
2012
High-temperature superconducting objects of Bi2Sr2CaCu2O8 and Y Ba2Cu3O7 highly curved in the ab-plane, such as curved/kinked whiskers, bows and ring-like structures, were obtained within a solid?liquid?solid (SLS) grass-like growth mechanism. As-grown objects are crystals with three-dimensional epitaxy similar to conventional single crystals: they can be viewed as crystal parts ?cut? from a conventional rectangular crystal. Between our curved objects and conventional crystals, whiskers or thin films there are some differences in the superconducting properties induced only by the shape factors and no new physics is observed. Some details of the growth mechanism are discussed, emphasizing cu…

Jakamistalous ja solidaarisuustalous : uusien talousmuotojen erottelun tarpeesta
2017
Tässä tekstissä analysoimme kahta uuden talouden muotoa, jakamistaloutta ja solidaarisuustaloutta.Tarkoituksemme on osoittaa, että nämä talousmuodot on syytä nähdä selvästi erillisinä sekä yhteiskuntatieteellisessä selittämisessä että näiden talousmuotojen sääntelyä pohdittaessa. nonPeerReviewed

Tutkimus keskittyi Namibiaan, joka on yksi maailman epätasa-arvoisimmista maista. Tarkoituksena oli kehittää kehysanalyysityökalu, jonka avulla voidaan selvittää millaisia yhteiskunnallisia rooleja niin kutsutut eliittisanomalehdet ehdottavat lukijoilleen, jotka edustavat epätasa-arvoisen yhteiskunnan hyväosaisia – käytännössä eliittejä ja keskiluokkia, joita tutkimus kutsui yhteisellä nimellä eliitit. Tarkastelu nojasi näkemykseen mediateksteistä laajempien yhteiskunnallisten diskurssien peileinä ja muokkaajina. Kehitetty työkalu perustuu käsitteeseen, jonka tutkimus nimeää eliittien yhteiskunnalliseksi vastuuksi. Käsite korostaa toiminnan merkitystä ja perustuu William Gamsonin kollektiiv…

The promotion of students’ engagement with school is an internationally acknowledged challenge in education. There is a need to examine the structure of the concept of student engagement and to discover the best practices for fostering it across societies. That is why the cross-cultural invariance testing of students’ engagement measures is highly needed. This study aimed, first, to find the reduced set of theoretically valid items to represent students’ affective and cognitive engagement forming the Brief-SEI (brief version of the Student Engagement Instrument; SEI; Appleton, Christenson, Kim, & Reschly, 2006). The second aim was to test the measurement invariance of the Brief-SEI across t…
