Una sociologia delle imposture legittimate. La costruzione del campo giuridico
2017
Il saggio introduttivo alla traduzione de «La forza del diritto» di Pierre Bourdieu definisce il profilo intellettuale e la cassetta degli attrezzi dell'autore e ricostruisce gli assunti teorici alla base della sua sociologia del campo giuridico. The introductory essay to the translation of Pierre Bourdieu's "The Force of Law" defines the author's intellectual profile and toolbox and reconstructs the theoretical assumptions underlying his sociology of the legal field.
The effect of spatial and temporal scale on camouflage in North African rodents
2022
Abstract Background matching, a common form of camouflage, is a widespread anti-predator adaptation that hinders detection or recognition by increasing the resemblance of prey to its environment. However, the natural environment is complex and both spatially and temporally variable, which constrains effective background matching as an anti-predator strategy. Here, using remote sensing data (publicly available satellite imagery), we investigated how variation of habitat parameters predicts background matching in 16 Sahara–Sahel rodent species across spatial and temporal scales. All fur colour parameters (hue, saturation and brightness) strongly matched the respective habitats of the differen…
Maternal effects in the magpie
2006
Marjo Pihlaja tutki väitöskirjatyössään äitivaikutusten merkitystä sopeumana vaihteleviin ympäristöoloihin käyttäen tutkimuslajina luonnonvaraisena pesiviä harakoita. Äitivaikutuksiin kuuluvat äidiltä jälkeläisille siirtyvät ympäristön äidille aiheuttamat ilmiasun piirteet sekä emon jakamien resurssien vaikutukset jälkeläisten ilmiasuun. Pihlaja tutki lintuja, mutta monet hänen tutkimansa mekanismit toimivat myös nisäkkäillä – siis myös ihmisillä.Pihlajan tavoitteena oli selvittää, peilaako munassa olevien yhdisteiden määrä vain emon kuntoa pesimäkauden alussa ja muninnan aikana, vai voiko näiden poikaselle tarjolla olevien yhdisteiden määrän vaihtelun takana olla myös evolutiivisesti merki…

Changement climatique et suivi de la biodiversité marine côtière aux Iles Kerguelen
2018
Nearshore marine habitats of the French sub-Antarctic islands concentrate a rich and unique biodiversity that is currently facing climate change and its still not well-understood and multifaceted effects. Understanding the impact of these changes and predicting the potential response of ecosystems requires advanced knowledge of marine life and the achievement of uninterrupted and long-term observing programs. The Proteker program, no. 1044 of the French Polar Institute Paul-Émile Victor, has been developped in partnership with the National Nature Reserve of French Southern Territories in order to establish an observatory of coastal marine biodiversity in the Kerguelen Islands and evaluate t…
Tutkimus kirjoittamisen tilan luomisesta : subjunktiivi, flow, rituaali ja habitaatti
2017
Tutkin luovan kirjoittamisen tilan luomista. Hahmotan, mistä tekijöistä se muodostuu ja millaisessa suhteessa nämä osatekijät ovat toisiinsa. Erityisen kiinnostunut olen siitä, millainen on pitkään jatkunut luovan kirjoittamisen tila erään tarinan osalta, ja millä tavoin pitkäaikaisuus ja jatkuvuus ovat vaikuttaneet tuohon tilaan. Pro gradu -tutkielmani on autoetnografinen tapaustutkimus ja aineistona toimii työskentelypäiväkirjani, jota pidin vuoden ajan pitkään kirjoittamani tarinan parissa työskentelystä tätä tutkielmaa varten. Luovuutta lähestyn psykologian näkökulmasta: Mihaly Csikszentmihalyin mukaan luovuus on prosessi, jonka kautta muutetaan ja muokataan kulttuurin symbolista aluett…
The Eurasian Treecreeper (Certhia familiaris) has an effective camouflage against mammalian but not avian vision in boreal forests
2022
A well-known example of visual camouflage in birds is the plumage coloration of the Eurasian Treecreeper Certhia familiaris, yet this species’ camouflage has never been objectively quantified. Here, we quantify treecreeper camouflage in its boreal forest habitat, test whether treecreepers better match tree backgrounds at nest site, territory or habitat spatial scales, and explore which common tree species provide the best background match. Using photographic data of the birds and forested backgrounds, we test their background match using human, ferret and avian vision modelling. We found that a treecreeper’s wing and mantle provided closest background matching, whereas the wing stripe and t…
Habitual physical activity and heart rate variability in 12-year old children
2012
ABSTRACT Wennman, Heini 2012. Habitual physical activity and heart rate variability in 12-year old children. Department of Biology of Physical Activity, University of Jyväskylä, 92p. The study of heart rate variability (HRV) provides useful information about the function of the cardiac autonomic nervous system. The effects of many environmental factors on HRV are well known, but the associations between physical activity (PA) and HRV, especially in children, are less investigated. Higher HRV is related to health and many pathologic conditions are associated with reduced HRV. Exercise causes HRV to diminish, but improves HRV in long term. PA promotes many health related changes in energy met…
Spatially dynamic forest management to sustain biodiversity and economic returns.
2014
Production of marketed commodities and protection of biodiversity in natural systems often conflict and thus the continuously expanding human needs for more goods and benefits from global ecosystems urgently calls for strategies to resolve this conflict. In this paper, we addressed what is the potential of a forest landscape to simultaneously produce habitats for species and economic returns, and how the conflict between habitat availability and timber production varies among taxa. Secondly, we aimed at revealing an optimal combination of management regimes that maximizes habitat availability for given levels of economic returns. We used multi-objective optimization tools to analyze data fr…
