Fashion versus perception: the impact of surface lightness on the perceived dimensions of interior space.

2011

Objectives: We compare expert opinion with perceptual judgment regarding the influence of color on the perceived height and width of interior rooms. Background: We hypothesize that contrary to popular belief, ceiling and wall lightness have additive effects on perceived height, whereas the lightness contrast between these surfaces is less important. We assessed the intuitions of architectural experts as to which surface colors maximize apparent height and compared these intuitions with psychophysical height and width estimates for rooms differing in ceiling, floor, and wall lightness. Method: Experiment 1 was a survey of architectural experts and nonexperts. Experiments 2 and 3 presented v…

Sustainability in executive remuneration : A missing link towards more sustainable firms?

2021

This paper contributes by showing simultaneously the interlinked challenges of sustainability-based (based on long-term economic, social and environmental targets) executive remuneration and the problems of transparency in remuneration reporting. Our empirical data, analyzed using qualitative content analysis, consists of the published remuneration statements and sustainability reports of 43 Finnish companies reporting according to the Global Reporting Initiative (GRI) framework. Our results indicate that comprehensive sustainability remuneration is still rare in Finnish large companies: long-term financial targets are implemented at most companies, but social or environmental targets were …

The bryophyte flora of Lågskär - An isolated island in the Baltic Sea

2014

This study reports the bryophyte flora of Lågskär, an isolated lighthouse island in the Åland province of Finland. A total of 81 bryophyte species were found on Lågskär, including 74 moss species and seven liverwort species. Syntrichia ruraliformis is reported for the first time in Finland, whereas Ceratodon conicus was believed to be extinct in Finland and Brachythecium turgidum was considered regionally extinct from southern Finland. peerReviewed

Ikäperusteinen digitaalinen kahtiajako vanhuksien osalta

2017

Tämä kandidaatintutkielma käsittelee ikäperusteista digitaalista kahtiajakoa vanhuksien osalta. Tutkielmassa käsitellään muun muassa mahdollisia haittoja, joita digitaalinen kahtiajako vanhimmille ikäluokille voi aiheuttaa jatkuvasti enenevissä määrin teknologistuvissa yhteiskunnissa tai niin kutsutuissa tietoyhteiskunnissa sekä vanhuksia koskevan ikäperusteisen digitaalisen kahtiajaon olemassaoloa, suuruutta ja syitä. Kahtiajaon syiden tutkimisessa käytetään apuna myös teknologian omaksumista selittäviä TAM- ja UTAUT-malleja. Tutkimus toteutetaan kirjallisuuskatsauksena teorialähtöisesti. Tutkielman aihepiiristä löytyy runsaasti aikaisempaa tutkimusta, mutta on huomionarvoista, että suuri …

Direct assessment of the sensitivity drift of SQM sensors installed outdoors

2021

Long-term monitoring of the evolution of the artificial night sky brightness is a key tool for developing science-informed public policies and assessing the efficacy of light pollution mitigation measures. Detecting the underlying artificial brightness trend is a challenging task, since the typical night sky brightness signal shows a large variability with characteristic time scales ranging from seconds to years. In order to effectively isolate the weak signature of the effect of interest, determining the potential long term drifts of the radiance sensing systems is crucial. If these drifts can be adequately characterized, the raw measurements could be easily corrected for them and transfor…

Metallimalmikaivosten vesistövaikutukset : esimerkkinä Talvivaaran kaivoksen sulfaatti-, natrium- ja mangaanipäästöt

2013

Mining industry is expanding in Finland and it is expected to become a forerunner in taking environmental issues into account in its processes. Mines often lower the water quality of their surrounding waters and this may lead to salinization and eutrophication for instance. Salinization may be due to dissolved ions in the wastewater, like sulphate and sodium, and may cause the artificial stratification of a lake. Sulphate can also prevent the natural circulation of iron in the sediments, which favors the release of phosphorus and could lead to eutrophication. All impacts cannot be assessed in advance and not enough studies have been made concerning these substances. The Talvivaara mine in S…

Vuosikymmenet suomalaisen hiihtohistorian kulisseissa : tapaustutkimus vapaaehtoistoiminnan merkityksistä ja muutoksista Lahden MM-hiihdoissa

2017

Lahden Salpausselällä on pitkät perinteet pohjoismaisten hiihtolajien kilpailuareenana. Pohjoismaisten hiihtolajien MM-kilpailut on järjestetty siellä yhteensä seitsemän kertaa seitsemällä eri vuosikymmenellä. Lisäksi Lahdessa on kilpailtu vuosittain pohjoismaisten hiihtolajien maailmancupin osakilpailut, Salpausselän kisat. Kumpaakaan näistä tapahtumista ei oltaisi voitu järjestää vuosien saatossa ilman sitoutuneiden ja kokeneiden vapaaehtoisten joukkoa. Lukuisat vapaaehtoiset ovat olleet mukana kisojen vapaaehtoistoiminnassa jo useamman vuosikymmenen ajan. Tässä laadullisessa tapaustutkimuksessa selvitettiin, millaisia merkityksiä pitkään vapaaehtoisena toimineet antavat vapaaehtoistoimin…

Latest Cretaceous storm-generated sea grass accumulations in the Maastrichtian type area, the Netherlands – preliminary observations

2019

Abstract Ever since the first description of fossil material during the mid-nineteenth century, sea grass has been shown to be quite commonly preserved in ‘pockets’ or ‘clumps’ at certain levels within the Gulpen, Maastricht and Kunrade formations in southern Limburg (the Netherlands) and contiguous areas in northeast Belgium. In those places where silicification occurred during early diagenesis, even completely silicified and three-dimensionally preserved stems and roots can be found, mostly of Thalassocharis bosquetii, in association with fully marine molluscs such as dentaliid scaphopods and a range of larger foraminifera, bivalves, gastropods and ammonites. Such occurrences are best kno…
