Brominated flame retardants and organochlorines in the European environment using great tit eggs as a biomonitoring tool

2009

Large-scale studies are essential to assess the emission patterns and spatial distribution of organohalogenated pollutants (OHPs) in the environment. Bird eggs have several advantages compared to other environmental media which have previously been used to map the distribution of OHPs. In this study, large-scale geographical variation in the occurrence of OHPs, such as polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs) and organochlorine pesticides (OCPs), was investigated throughout Europe using eggs of a terrestrial residential passerine species, the great tit (Parus major). Great tit eggs from 22 sampling sites, involving urban, rural and remote areas, in 14 Europea…

Short- and long-term population dynamical consequences of asymmetric climate change in black grouse

2006

Temporal asymmetry in patterns of regional climate change may jeopardize the match between the proximate and ultimate cues of the timing of breeding. The consequences on short- and long-term population dynamics and trends as well as the underlying mechanisms are, however, often unknown. Using long-term data from Finland, we demonstrate that black grouse ( Tetrao tetrix ) have responded to spring warming by advancing both egg-laying and hatching. However, early summer (the time of hatching) has not advanced, and chicks have to face colder post-hatching conditions. Demonstrating that these conditions are critical to post-hatching survival, we show that chicks are increasingly suffering highe…

La transparencia y la rendición de cuentas en redes sociales. Un caso de conflictos mineros en Latinoamérica

2021

Diversos estudios muestran un creciente uso del Internet y las redes por parte de grandes empresas para divulgar información social y medioambiental, ampliando la rendición de cuentas y la transparencia. No obstante, aún no existe claridad sobre los pros y contras de dicho proceso. Este trabajo plantea la necesidad de una reinterpretación crítica de la transparencia y la rendición de cuentas sociales y medioambientales a través de las redes sociales. Para ello, retoma algunos argumentos de la perspectiva dialógica de la rendición de cuentas, así como planteamientos del filósofo coreano Byung-Chul Han. Se estudia el caso de la compañía minera Vale, caracterizando la forma en qu…

Épigraphie religieuse et communautés civiques au Haut-Empire : la délimitation du territoire de la ciuitas Aeduorum aux IIe et IIIe siècles

2013

Since the 19th century, many proposals have been made regarding the boundaries of the territory of the civitas Aeduorum. Although there is general agreement on many geographic sectors, there are still major discrepancies of opinion, principally in the regions of Autissiodurum / Auxerre and Alesia. The religious epigraphy of the Early Empire, in particular the use of a specific formulary, seems to demonstrate a single religious (and political) community in these regions, which would thus have all belonged to the civitas Aeduorum in the 2nd and 3rd centuries.

Bioethics and power: Informed consent procedures in post-socialist Latvia

2013

This paper explores two lines of development in the donor consent procedures in post-Soviet Latvia. The paper is based on secondary analysis of interview, focus group discussion data, and media and legal text material collected throughout three previously conducted research projects on organ transplantation, population genome project and xenotransplantation focusing on the historical development of the issues of donor consent across these three fields of medical technologies. The paper argues that the quality of consent depends not as much on political and legal change per se as on the strengthening of the position of both medical specialists and donors, facilitating bonds between the two.

Country-specific correlations across Europe between modelled atmospheric cadmium and lead deposition and concentrations in mosses

2012

Previous analyses at the European scale have shown that cadmium and lead concentrations in mosses are primarily determined by the total deposition of these metals. Further analyses in the current study show that Spearman rank correlations between the concentration in mosses and the deposition modelled by the European Monitoring and Evaluation Programme (EMEP) are country and metal-specific. Significant positive correlations were found for about two thirds or more of the participating countries in 1990, 1995, 2000 and 2005 (except for Cd in 1990). Correlations were often not significant and sometimes negative in countries where mosses were only sampled in a relatively small number of EMEP gr…

Ville et fortifications : de l'héritage à la production du territoire urbain

2015

A large number of french cities host military historical edifices (citadels, barracks, bastions, defensive walls, etc.). Although their initial defensive functions have been lost over time, these edifices remain deeply rooted in the urban fabric of their host cities. They continue exerting an impact on these cities’ urban morphology and modern-time functions as well as the way in which the concept of city is understood. Cities nowadays face some new challenges,the increasing awareness of urban sprawl and its consequences, coupled with an urge to promote a renewed and sustainable urbanism, invites us to adopt new approaches to study urban fortifications. In addition to their symbolic aspect,…
