CH4 oxidation in a boreal lake during the development of hypolimnetic hypoxia

2020

AbstractFreshwater ecosystems represent a significant natural source of methane (CH4). CH4 produced through anaerobic decomposition of organic matter (OM) in lake sediment and water column can be either oxidized to carbon dioxide (CO2) by methanotrophic microbes or emitted to the atmosphere. While the role of CH4 oxidation as a CH4 sink is widely accepted, neither the magnitude nor the drivers behind CH4 oxidation are well constrained. In this study, we aimed to gain more specific insight into CH4 oxidation in the water column of a seasonally stratified, typical boreal lake, particularly under hypoxic conditions. We used 13CH4 incubations to determine the active CH4 oxidation sites and the …

Growth form matters – Crustose lichens on dead wood are sensitive to forest management

2022

Lichens have a vital role in forest ecosystems and they are a threatened group in boreal forests. However, the conservation ecology of the total lichen community has very rarely been studied. Here we studied lichen species and communities, including macrolichens (=foliose and fruticose growth forms) and rarely studied crustose li-chens, on decaying wood in boreal spruce-dominated forests in Finland. We also studied obligate lignicoles that grow only on dead wood and are mostly crustose in growth form. Species richness and community composition were examined on decaying logs and natural or cut stumps of Picea abies at different decay stages (2-5) in 14 stands, half of which were natural or s…

Agency and Learning in the Work of Software Professionals

2017

This chapter addresses software professionals’ agency and learning in work characterized by a need for innovative learning and fluency in renewing work practices. The study presented was conducted with software professionals in a medium-sized Finnish company producing digital business applications. We applied a mixed-method approach to data collection and analysis. Regarding professional agency, we found a range of opportunities to influence work-related matters. The professionals were primarily able to influence their working hours and the order of their work tasks, but had fewer opportunities to influence customer projects, or their salary. To some extent they were able to develop themsel…

Social Media Monitoring for Crisis Communication: Process, Methods and Trends in the Scientific Literature

2014

This literature review study aims at clarifying current knowledge on social media monitoring from the perspective of organizational communication and public relations. It also contributes to crisis communication by shedding light on how fast developing social media discourse can be followed and analysed in order to understand citizens’ needs throughout all the phases of a crisis. The findings of this study reveal a number of insights in the scientific literature on the concept of monitoring, the monitoring process, methods, tools and solutions, methodological issues and trends covering the years 2009–2012. In the literature, social media monitoring is described as a process which comprises …

Millaista demokratiaa? : diskurssianalyysi tavoitellun kuntaliitoksen (Oulainen-Vihanti) keskusteluista vuosina 2011-2014

2014

Demokratian kehitys on huolestuttanut suomalaisia pitkään. Alenevat äänestysprosentit ja vaisu osallistuminen yhteisten asioiden hoitoon ovat saaneet aikaan sen, että Suomen valtiohallinnossa on paneuduttu voimakkaasti demokratian ongelmien kartoittamiseen ja suotuisan kehityksen aikaansaamiseen. Tämän tutkielman tarkoituksena on selvittää kuntaliitosargumentaatiota vuosien 2011–2014 ajalta entisen Vihannin kunnan valtuuston pöytäkirjoista, paikallislehdistä ja kuntalaisten kommenteista sosiaalisessa mediassa. Ensiksi tarkastelun kohteena ovat argumentaatiot puolesta ja vastaan, kun kyseessä on Vihannin eteläosien liittäminen Oulaisten kaupunkiin. Toiseksi pureudutaan siihen, millaisena dem…

Polypyridyl-functionalizated alkynyl gold(i) metallaligands supported by tri- and tetradentate phosphanes

2017

A series of alkynyl gold(I) tri and tetratopic metallaligands of the type [Au3(CuC-R)3(μ3-triphosphane)] (R = 2,2'-bipyridin-5-yl or C10H7N2, 2,2':6',2''-terpyridin-4-yl or C15H10N3; triphosphane = 1,1,1-tris(diphenylphosphanyl) ethane or triphos, 1,3,5-tris(diphenylphosphanyl)benzene or triphosph) and [Au4(CuC-R)4 (μ4-tetraphosphane)] (R = C10H7N2, C15H10N3; tetraphosphane = tetrakis(diphenylphosphanylmethyl)methane or tetraphos, 1,2,3,5-tetrakis(diphenylphosphanyl)benzene or tpbz, tetrakis(diphenylphosphaneylmethyl)-1,2- ethylenediamine or dppeda) were obtained in moderate to good yields. All complexes could be prepared by a Q4 reaction between the alkynyl gold(I) polymeric species [Au(Cu…

John Dewey’s notion of social intelligence

2019

This chapter focuses on Deweyan understanding of intelligence as fundamentally social. This understanding differs from the common conceptions of intelligence as a feature of an isolated individual and/or as a possession of an elite. Starting with a look at the relevance of reconceptualizing intelligence, the chapter continues by describing how, according to Dewey’s theory, intelligence forms, manifests and cumulates in interactions. It then discusses the presumable implications of Dewey’s theory in terms of the contextuality of intelligent action, the importance of taking relevant experience-based information into account, the use of a particular method of inquiry, and modification of educa…
