Selection on two behavioral genes : fitness effects of receptor genes for arginine vasopressin 1a and oxytocin in the bank vole Myodes glareolus

2017

Most variation in behavior is regulated by genes; nevertheless the mechanisms behind maintenance of genetic diversity at behavioral loci have remained mainly elusive in natural populations. I studied in my thesis selection mechanisms of two genes associated with socio-sexual behavior, arginine vasopressin receptor 1a (Avpr1) and oxytocin receptor (Oxtr) in bank vole (Myodes glareolus). Expression of Avpr1a and Oxtr in specific regions of the brain regulates diverse social and reproductive behaviors such as parental care, aggression, sexual behavior, social recognition as well as pair and parent- offspring bonding in mammals. In addition, there is a link between the length of a regulatory re…

Kytkeytyneisyyttä edistävät politiikkakeinot ja vihreä infrastruktuuri : miten luonnon monimuotoisuus saadaan säilytettyä?

2013

Luonnon monimuotoisuuden vähenemistä ei ole saatu pysäytettyä kansainvälisistä sopimuksista huolimatta. Ekologinen kytkeytyneisyys on välttämätöntä, jotta monimuotoisuus voisi säilyä pitkällä aikavälillä. Tämä pro gradu tutkii luonnon monimuotoisuuden ja ekosysteemien prosessien säilyttämistä edistäviä politiikkakeinoja kolmen tutkimuskysymyksen avulla: 1) Kuinka hyvin nykyiset luonnonsuojelupolitiikan keinot edistävät ekologista kytkeytyneisyyttä? 2) Miten luonnonsuojelupolitiikan keinot voisivat edistää ekologista kytkeytyneisyyttä paremmin? 3) Voiko vihreä infrastruktuuri -lähestymistapa auttaa luonnon monimuotoisuuden suojelussa? Ekologinen kytkeytyneisyys vaikuttaa erityisesti lajien l…

Justice in and to nature : an application of the broad framework of environmental and ecological justice

2017

This dissertation applies and develops the broad framework of environmental and ecological justice. It is a new relational approach to justice, whose elements have been introduced by David Schlosberg in his works on environmental and ecological justice. The present study provides a systematisation of the framework and applies it to contemporary environmental topics using the methods of conceptual analysis and case-implication critique. The main outcome of this study is that the elements comprising the broad framework of environmental and ecological justice provide fresh and useful insights into topics like species extinctions and ecosystem wellbeing. In particular, the holistic and conflict…

Further notes on sociolinguistic scales

2015

AbstractThis short paper seeks to reformulate and refine the notion of sociolinguistic scales as relative scope of understandability, thus drawing the notion fully into the realm of semiotics, rather than in the rather unproductive sphere of spatiotemporal and distributional interpretation where it has been deployed. Differences in scope of understandability are differences in the presupposability of signs, and such differences are not equivalent but stratified in a polycentric environment. Scales, in that sense, point towards the non-unified and hierarchical-layered nature of the sign and of meaning making practices. Scalar effects, once established, can furthermore be carried over into di…

Meta-analyysin ja metaregression soveltaminen fyysistä aktiivisuutta mittaaviin tutkimuksiin

2017

Tieteellistä tietoa tuotetaan jatkuvasti lisää, mutta sen yhdistäminen aiempaan tietämykseen ei ole ongelmatonta. Tilastotieteellisesti tätä pulmaa lähestytään meta-analyysin ja metaregression avulla. Meta-analyysi on systemaattisessa kirjallisuuskatsauksessa kerätyn aineiston tilastollista yhteenvetoa; useista estimaateista luottamusväleineen muodostetaan yksi keskimääräinen estimaatti ja sen luottamusväli. Huomattavaa on, että meta-analyysin aineisto on eräänlainen aineistojen aineisto; havaintoyksiköitä eivät ole tutkimuksiin osallistuvat koehenkilöt vaan itse tutkimukset. Metaregressio on meta-analyysiä, jossa yhteenveto tehdään hyödyntämällä tutkimusten taustamuuttujia eli kovariaattej…

The effects of grazing history, soil properties and stand structure on the communities of saprotrophic fungi in wood-pastures

2022

Wood-pastures are threatened anthropogenic biotopes that provide habitat for an extensive group of species. Here we studied the effect of management, grazing intensity, time since abandonment, historical land-use intensity, soil properties and stand conditions on communities of saprotrophic fungi in wood-pastures in Central Finland. We found that the proportion of broadleaved trees and soil pH are the major drivers in the communities of saprotrophic fungi in these boreal wood-pastures. In addition, tree species richness, soil moisture, historical land-use intensity and time since abandonment affected the communities of saprotrophic fungi. Current management or grazing intensity did not have…

Forme del mangiar per strada: il caso della rosticceria palermitana

2019

Analizziamo qui un tipo di cibo da strada noto a Palermo come rosticceria. Si tratta di un insieme coerente e composito di pietanze che fanno parte di una gastronomia locale, popolare ed economica, e con una valorizzazione fortemente pratica: puro “cibo rifornimento”. Eppure, attraverso un’analisi interna della rosticceria, considerando gli elementi che la compongono e le relazioni tra di essi, nonché attraverso un confronto con altri universi gastronomici, vedremo come sia possibile individuare le forme semiotiche profonde che reggono il funzionamento socio-culturale di questo cibo molto diffuso, e al tempo stesso un po’ snobbato, della gastronomia palermitana. È solo nel confronto che si …

Yhteisöllinen argumentointi sosionomikoulutuksessa avoimia ongelmia ratkottaessa

2017

The aim of this study was to develop teaching methods for practising argumentative problem-solving in a degree program of social services. The purpose was to acquire knowledge about multiple (face-to-face, online, and integrated) learning environments for studying argumentative problem-solving. In addition, the typical features of collaborative argumentation in student discussions were identified. Two teaching experiments were arranged in courses on drug and alcohol abuse. Both experiments required students to solve open-ended problems through role-play regarding a fictive girl’s use of alcohol. The idea of blended learning was applied in the first teaching experiment. Students (n = 29) wro…
