Economical evaluation of ecological benefits of the demand side management
2014
Environmental pollution and over-exploitation of non-renewable sources to find energy are current topics for the modern world that is now at having to deal with several issues such as the greenhouse effect, acid rain and climate change. In this study, the economical estimate of the savings in carbon dioxide obtained with a careful management of electrical loads is presented. Four particular scenarios are designed as case studies: Italy, France, United Kingdom and Germany. A comparison is presented with a similar study, made in 2007, when green energies were not yet very developed.
Grazing intensity in subarctic tundra affects the temperature adaptation of soil microbial communities
2015
Abstract Grazing by large ungulates, such as reindeer (Rangifer tarandus L.), in subarctic tundra exerts a considerable effect on the soil microclimate. Because of higher insulation by the aboveground vegetation in light versus heavily grazed areas, soil temperatures during the growing season are considerably higher under heavy grazing. Here, we hypothesized that these grazer-induced changes in soil microclimate affect the temperature sensitivity of soil microbial activity. To test this hypothesis, we conducted soil incubations at different temperatures (4 °C, 9 °C and 14 °C) for six weeks using soils from sites with contrasting long-term grazing intensities. Microbial respiration at low te…
Global, National, or Market? Emerging REDD+ Governance Practices in Mozambique and Tanzania
2016
This article examines emerging governance practices in the REDD (Reducing Emissions from Deforestation and Forest Degradation) initiative. We examine three different general governance practices (neoliberal, post-national, and government-led practices) that have been applied in the interaction between international organizations and two REDD target countries: Mozambique and Tanzania. In these countries, we find that emerging REDD+ governance practices are a mixture of international organizations’ procedural practices and the target country’s established governance practices, whereas neoliberal practices are weakly expressed. These findings call into question the simplified assumption of re…
Assessing travel time-based accessibility to outdoor ice skating fields for children in Helsinki during the COVID-19 pandemic
2022
This paper was written within the research project called “Equality in suburban physical activity environments, YLLI” (in Finnish: Yhdenvertainen liikunnallinen lähiö, YLLI) funded by the Suburban Programme 2020–2022 (in Finnish: Lähiöohjelma 2020–2022, decision number VN/10837/2020). Informal sport is central to Finnish children’s leisure and physical activity time. This paper aims to build a better understanding of the travel time-based accessibility to informal sports facilities, specifically to ice skating fields, for children and adolescents (aged 7–19) in the city of Helsinki. We focused on the winter of 2020–2021 because COVID-19 restrictions on indoor activities resulted in ice skat…
The effect of perceived school climate and teacher efficacy in behavior management on job satisfaction and burnout: A longitudinal study
2016
Abstract This study investigated how perceived school climate affects teachers' job satisfaction and burnout and how self-efficacy and collective efficacy in behavior management mediate the effect of perceived school climate on job satisfaction and burnout. The questions were answered using longitudinal questionnaire data collected from 642 Finnish lower secondary school teachers. A structural equation model revealed that school climate had a positive effect, partly mediated by self-efficacy, on job satisfaction. Collective efficacy in student discipline did not explain either job satisfaction or burnout. Self-efficacy in managing behavior had a positive effect on job satisfaction and a neg…
School climate as predictor of teachers’ competences to recognize the educational needs of adopted children in Italy
2019
The current study examines the association between different components of school climate (teacher-principal and teacher-parent relationships, parents’ involvement in school activities, connection between school and the local services) and teachers’ competences and knowledge regarding the adoption experience. Participants were 573 teachers (95.7% women; mean age= 47.06, SD= 8.66, ranging between 25 and 65) residing in three Italian regions characterized by rates of international adoptions that are higher than the national average. The association between school climate and teachers’ knowledge and competences on adoption was evaluated via independent multiple logistic regression analyses. Fi…

El ciberacoso es un fenómeno de creciente preocupación social que afecta cada vez más a niños y adolescentes de todos los paí- ses desarrollados. A diferencia de la considerable literatura que hay sobre las relaciones entre el acoso escolar y el contexto familiar y escolar, todavía hay pocos trabajos sobre la influencia de estos entornos sociales en el problema del ciberacoso. Mediante una metodología cuantitativa, el objetivo principal del presente estudio fue analizar la influencia del contexto escolar y familiar en víctimas de ciberacoso. La muestra estuvo formada por 1.062 adolescentes (51,5% chicos y 48,5% chicas), de edades comprendidas entre los 12 y los 18 años (M=14,5; DT=1,62). Se…
Atmospheric brightening counteracts warming‐induced delays in autumn phenology of temperate trees in Europe
2021
Aim: Ongoing climate warming has been widely reported to delay autumn phenology, which in turn impacts carbon, water, energy and nutrient balances at regional and global scales. However, the underlying mechanisms of autumn phenology responses to climate change have not been fully elucidated. The aims of this study were to determine whether brightening that was defined as the increase of surface solar radiation and warming during recent decades affect autumn phenology in opposite directions and explore the underlying mechanisms. Location: Central Europe. Time period: 1950–2016. Major taxa studied: Four dominant European tree species in central Europe: Aesculus hippocastanum, Betula pendula, …
Caractérisation fine du climat en serre expérimentale - Cas de la plateforme 4PMI de l’INRA de Dijon
2019
Les conditions environnementales dans lesquelles sont cultivées les plantes influent grandement surleurs caractéristiques observables, i.e. leur phénotype. Les conditions environnementales d’une serren’étant pas homogènes, elles peuvent induire un biais lors de l’analyse des résultats de phénotypage.Afin de mieux contrôler ce biais, la plateforme « Plant Phenotyping Platform for Plant Micro-organismsInteractions » (4PMI) hébergée par le Centre INRA de Dijon a mis en place un système decaractérisation du climat de chaque plante dans ses serres. Le développement de ce protocole a faitl’objet de ce stage. Dans un premier temps un système de collecte et de gestion des donnéesclimatiques produit…
