Atmospheric circulation modulates the spatial variability of temperature in the Atlantic-Arctic region
2019
International audience; The Arctic region has experienced significant warming during the past two decades with major implications on the cryosphere. The causes of Arctic amplification are still an open question within the scientific community, attracting recent interest. The goal of this study is to quantify the contribution of atmospheric circulation on temperature variability in the Atlantic–Arctic region at decadal to intra‐annual timescales from 1951 to 2014. Daily 20th Century reanalyses geopotential height anomalies at 500 hPa were clustered into different weather regimes to assess their contribution to observed temperature variability. The results show that in winter, 25% of the warm…
Habitat area and local habitat conditions outweigh fragmentation effects on insect communities in vineyards
2022
Fragmentation of habitat, for example by intensive agricultural practices, can be detrimental to local biodiversity. However, it often remains unclear whether such biodiversity declines are caused by loss of habitat area or increased fragmentation, and how habitat quality factors into it. In our study system, vegetated vineyards are typically small, and isolated from one another, potentially limiting the distribution and dispersal of organisms. In a full-factorial experiment of a priori selected vegetated vineyard patches of differing size and fragmentation, we aimed to disentangle the effects of habitat area (area of vegetated vineyards), habitat fragmentation (number of vegetated vineyard…
The MIMOSE Approach to Support Sustainable Forest Management Planning at Regional Scale in Mediterranean Contexts
2017
In recent decades, Mediterranean landscapes have been affected by human-induced drivers, such as land use and climate change. Forest ecosystems and landscapes have been particularly affected in mountainous regions due to limited management and stewardship, especially in remote areas. Therefore, there is a need to set up new strategies to enhance ecosystem services in forested areas which, in turn, will benefit local communities and economies. In this study, we implemented a new approach—Multiscale Mapping of Ecosystem Services (MIMOSE)—to assess ecosystem services in Mediterranean forests located in a mountainous region of Italy. We spatially assessed timber provision and carbon sequestrati…
The audiovisual translation of wordplay illustrated by the example of the Ecuadorian web series Enchufe.tv
2018
The ongoing internationalization of audiovisual media increases the need for new ways of overcoming linguistic barriers. In Germany, where the common technique has always been dubbing, subtitles are however becoming more and more popular. The present article will deal with the application possibilities of subtitles in audiovisual translation with reference to humoristic elements. The article will present two theoretical approaches to the translation of humour which will be then put into practice by using three sketches of the Ecuadorian web series Enchufe.tv as an example. All three sketches are based on wordplays, a manifestation of humour which is extremely difficult to reproduce in other…
Digitaalinen diskurssi työelämän kontekstissa – menetelmällisiä haasteita ja ratkaisuehdotuksia
2020
Digital technologies have become an inseparable part of most workplace activities. In this article, we discuss the study of digital work in the context of complex organizational practices. We lay out some methodological challenges and suggest some possible solutions to them. Firstly, we contend that we should take into consideration the multimedial nature of organizational practices. Secondly, several kinds of data – such as video-recordings of face-to-face encounters, screenshots from digital platforms, ethnographic observation and interviews – may be needed to gain an understanding of such practices. Thirdly, the analyst needs to pay attention to the affordances of the media that the part…
Photocatalytic nano-composite architectural lime mortar for degradation of urban pollutants under solar and visible (interior) light
2017
Abstract Recent advances in nano-technology and nano-additives can give enhanced properties to natural hydraulic lime (NHL), creating a multifunctional material. We have prepared a novel nanocomposite, made of a commercial mortar with 1 wt% and 5 wt% added titania nanoparticles (NPs). These TiO 2 NPs are themselves doped with 1 mol% silver, to give the material enhanced photocatalytic and antimicrobial properties. The Ag-doped TiO 2 NPs were made from a simple, costs effective, aqueous green nanosynthesis process, and the end material only contains 0.01–0.05% Ag. As this mortar is intended to both combat atmospheric pollution, and create more durable/lower maintenance building facades (plas…
Analysis of the Potential of an Increase in Yeast Output Resulting from the Application of Additional Process Wastewater in the Evaporator Station
2019
This paper reports the results of an analysis of process wastewater streams in the context of an increase in yeast production. This research is based on the analysis of data from the biggest yeast factory in Europe. The research presented in this paper involves the analysis of the influence of direction of additional wastewater into the evaporator station on yeast production. In the process wastewater, nitrogen is mainly present in organic forms. The analysis reported in this paper involves the concentration of total nitrogen in wastewater streams, as it is the main parameter applied to determine the amount of wastewater that can be applied in agricultural fields. Directing additional waste…
Förståelighetsperspektiv på finlandssvenskars vanliga uttalsdrag i engelska
2022
The present investigation addresses the gravity of mispronunciation for the intelligibility of English spoken by L1 Finland-Swedish teenagers. Previous research on the topic has been scarce, and even though there is some knowledge about the typical pronunciation challenges faced by this learner group, there is hardly any empirical research on the extent to which the typical mispronunciations actually cause misunderstandings. To investigate this, speech samples were elicited from teenaged L1 Finland-Swedish learners of English, demonstrating typical mispronunciations. Then, an intelligibility test was arranged with L1 English listeners (n = 48) matching the speakers’ age. Results suggest tha…
Long-term changes in pigmentation of arctic Daphnia provide potential for reconstructing aquatic UV exposure
2016
Abstract Despite the biologically damaging impacts of solar ultraviolet radiation (UV) in nature, little is known about its natural variability, forcing mechanisms, and long-term effects on ecosystems and organisms. Arctic zooplankton, for example the aquatic keystone genus Daphnia (Crustacea, Cladocera) responds to biologically damaging UV by utilizing photoprotective strategies, including pigmentation. We examined the preservation and content of UV-screening pigments in fossil Daphnia remains (ephippia) in two arctic lake sediment cores from Cornwallis Island (Lake R1), Canada, and Spitsbergen (Lake Fugledammen), Svalbard. The aims were to document changes in the degree of UV-protective p…
Ruwen Ogien au secours des éducateurs scolaires : une pensée pour réduire quelques apories éducatives
2021
Les projets éducatifs sont, par nature, des visions enchevêtrées de moyens et d’objectifs qui tentent de faire face à des apories éducatives. Ce texte propose d’envisager les apports de la pensée de Ruwen Ogien pour cela. On y examine ainsi successivement les possibilités offertes pour la sanction éducative, l’orientation et la prise en charge de la difficulté scolaire au moyen des notions de « faiblesse de la volonté », de non-nuisance et de l’idée de supériorité des droits sur les valeurs. En fin de compte sont apportés quelques arguments montrant que le minimalisme moral défendu par Ogien peut permettre à la fois de penser de façon plus assurée certaines apories éducatives, tout en augme…
