Carbon dynamics in highly heterotrophic subarctic thaw ponds

2015

Abstract. Global warming has accelerated the formation of permafrost thaw ponds in several subarctic and arctic regions. These ponds are net heterotrophic as evidenced by their greenhouse gas (GHG) supersaturation levels (CO2 and CH4), and generally receive large terrestrial carbon inputs from the thawing and eroding permafrost. We measured seasonal and vertical variations in the concentration and type of dissolved organic matter (DOM) in five subarctic thaw (thermokarst) ponds in northern Quebec, and explored how environmental gradients influenced heterotrophic and phototrophic biomass and productivity. Late winter DOM had low aromaticity indicating reduced inputs of terrestrial carbon, wh…

Metabolic plasticity of mixotrophic algae is key for their persistence in browning environments

2022

Light availability is the main regulator of primary production, shaping photosynthetic communities and their production of ecologically important biomolecules. In freshwater ecosystems, increasing dissolved organic carbon concentrations, commonly known as browning, leads to lower light availability and the proliferation of mixotrophic phytoplankton. Here, a mixotrophic algal species (Cryptomonas sp.) was grown under five increasing dissolved organic carbon concentrations to uncover the plastic responses behind the success of mixotrophs in browning environments and their effect in the availability of nutritionally important biomolecules. In addition to the browning treatments, phototrophic, …

From monitoring to sharing of attention in dyadic interaction: The affordances of gaze data to better understand social aspects of remote collaborati…

2020

This paper aims to better understand the social aspects of collaborative problem solving (CPS) through studying joint attention behaviour (JAB) in an online game–like environment. To capture these behaviours and exemplify how ‘jointness’ is achieved in CPS in remote dyadic interaction, event-related measures are utilised based on the following multiple interaction data: (1) individuals’ gaze data from CPS task completion and (2) automatically generated log files (i.e. chats and actions) from dyadic interactions. The results give empirical evidence of the detached, individualistic attention experiences (i.e. monitoring and common attention) and of bidirectional relations (i.e. mutual and sha…

Designing a graphics processing unit accelerated petaflop capable lattice Boltzmann solver: Read aligned data layouts and asynchronous communication

2017

The lattice Boltzmann method is a well-established numerical approach for complex fluid flow simulations. Recently, general-purpose graphics processing units (GPUs) have become available as high-performance computing resources at large scale. We report on designing and implementing a lattice Boltzmann solver for multi-GPU systems that achieves 1.79 PFLOPS performance on 16,384 GPUs. To achieve this performance, we introduce a GPU compatible version of the so-called bundle data layout and eliminate the halo sites in order to improve data access alignment. Furthermore, we make use of the possibility to overlap data transfer between the host central processing unit and the device GPU with comp…

Media strategies in lobbying process. A literature review on publications in 2000-2018.

2019

This study examines how the media and journalists are used in lobbying processes. To explore the topic a systematic review of the literature in peer-reviewed journals published between January 2000 to June 2018 was undertaken. The findings of this paper indicate that lobbyists and interest groups engage with a plethora of various strategies and systematic methods when influencing or trying to advocate the work of journalists and media organisations. The findings shed the mystery of lobbyists and interest group’s communicative attempts. This study increases the knowledge of the relationships between journalists and lobbyists in lobbying processes. Based on the literature review, the paper pr…

What does the translator do when she takes a moment? : scriptlog-aided analysis of long pauses and dictionary use in a translation process

2010

Käännösprosessin tutkiminen on viime vuosina siirtynyt yhä enemmän lopputekstin tutkimisesta itse prosessin eri osien ja piirteiden tutkimukseen. Tauot ovat yksi tämän prosessin eniten tutkituista piirteistä, mutta tähän asti tutkimukset ovat keskittyneet lähinnä kahden tai maksimissaan viiden sekunnin pituisten taukojen analysointiin. Tämän tutkielman tavoitteena on selvittää, millaista informaatiota käännösprosessin kulusta ja sisällöstä sekä sen kääntäjäkohtaisuudesta saadaan ottamalla tutkimuskohteeksi aiempia tutkimuksia pidemmät tauot sekä sanakirjojen käyttö käännösprosessin aikana. Tämän tutkielman aineisto kerättiin hyödyntämällä tietokoneohjelmaa nimeltä Scriptlog, joka tallentaa …
