L'indicateur EU2020 de suivi de la pauvreté et de l'exclusion: une analyse critique

The reduction of poverty and social exclusion is one of the targets of the European Union's 2020 strategy. The appropriateness and success of such a policy require the choice of relevant indicators that not only highlight poverty gaps between countries but also identify the groups of individuals in each country that need particular attention from social policies. The target retained in the European strategy combines three criteria: people living in households below the monetary poverty threshold, poor people “in terms of standard of living” who live in a situation of severe material deprivation, and those who live in households with very low or zero work intensity. We first show that neither the combination nor the intersection of these three criteria produces an adequate measure of the fight against poverty, or an objective for it. We therefore propose an alternative concept, that of “consistent poverty”, which targets people who simultaneously live below the monetary poverty threshold and above a certain level of material deprivation. The special material deprivation module of the EU-SILC 2009 database allows us to examine two versions of this notion of deprivation: the measurement of “severe” deprivation currently used by the European Union, which adopts a threshold with four items, and an alternative measure of “elementary” material deprivation with a three-item threshold. The intersection between our three-item elementary deprivation criterion and the monetary poverty criterion produces more satisfactory results than those obtained by the European Union approach, in terms of both coherency and profile of the population identified.

Trace Element Abundance and Renal Disease

This research investigates the relationship between elevated trace elements in soils, stream sediments and stream water and the prevalence of Chronic Kidney Disease (CKD). The study uses a collaboration of datasets provided from the UK Renal Registry Report (UKRR) on patients with renal diseases requiring treatment including Renal Replacement Therapy (RRT), the soil geochemical dataset for Northern Ireland provided by the Tellus Survey, Geological Survey of Northern Ireland (GSNI) and the bioaccessibility of Potentially Toxic Elements (PTEs) from soil samples which were obtained from the Unified Barge Method (UBM). The relationship between these factors derives from the UKRR report which highlights incidence rates of renal impaired patients showing regional variation with cases of unknown aetiology. Studies suggest a potential cause of the large variation and uncertain aetiology is associated with underlying environmental factors such as the oral bioaccessibility of trace elements in the gastrointestinal tract.
As previous research indicates that long term exposure is related to environmental factors, Northern Ireland is ideally placed for this research as people traditionally live in the same location for long periods of time. Exploratory data analysis and multivariate analyses are used to examine the soil, stream sediments and stream water geochemistry data for a range of key elements including arsenic, lead, cadmium and mercury identified from a review of previous renal disease literature. The spatial prevalence of patients with long term CKD is analysed on an area basis. Further work includes cluster analysis to detect areas of low or high incidences of CKD that are significantly correlated in space, Geographical Weighted Regression (GWR) and Poisson kriging to examine locally varying relationship between elevated concentrations of PTEs and the prevalence of CKD.

Spatial and Temporal Changes in Soil Organic Carbon Assessment using an Integrated Geostatistical and Compositional Data Analysis Approach

The Irish and UK governments, along with other countries, have made a commitment to limit the concentrations of greenhouse gases in the atmosphere by reducing emissions from the burning of fossil fuels. This can be achieved (in part) through increasing the sequestration of CO2 from the atmosphere including monitoring the amount stored in vegetation and soils. A large proportion of soil carbon is held within peat due to the relatively high carbon density of peat and organic-rich soils. This is particularly important for a country such as Ireland, where some 16% of the land surface is covered by peat. For Northern Ireland, it has been estimated that the total amount of carbon stored in vegetation is 4.4Mt compared to 386Mt stored within peat and soils. As a result it has become increasingly important to measure and monitor changes in stores of carbon in soils. The conservation and restoration of peat covered areas, although ongoing for many years, has become increasingly important. This is summed up in current EU policy outlined by the European Commission (2012) which seeks to assess the relative contributions of the different inputs and outputs of organic carbon and organic matter to and from soil. Results are presented from the EU-funded Tellus Border Soil Carbon Project (2011 to 2013) which aimed to improve current estimates of carbon in soil and peat across Northern Ireland and the bordering counties of the Republic of Ireland.
Historical reports and previous surveys provide baseline data. To monitor change in peat depth and soil organic carbon, these historical data are integrated with more recently acquired airborne geophysical (radiometric) data and ground-based geochemical data generated by two surveys, the Tellus Project (2004-2007: covering Northern Ireland) and the EU-funded Tellus Border project (2011-2013) covering the six bordering counties of the Republic of Ireland, Donegal, Sligo, Leitrim, Cavan, Monaghan and Louth. The concept being applied is that saturated organic-rich soil and peat attenuate gamma-radiation from underlying soils and rocks. This research uses the degree of spatial correlation (coregionalization) between peat depth, soil organic carbon (SOC) and the attenuation of the radiometric signal to update a limited sampling regime of ground-based measurements with remotely acquired data. To comply with the compositional nature of the SOC data (perturbations of loss on ignition [LOI] data), a compositional data analysis approach is investigated. Contemporaneous ground-based measurements allow corroboration for the updated mapped outputs. This provides a methodology that can be used to improve estimates of soil carbon with minimal impact to sensitive habitats (like peat bogs), but with maximum output of data and knowledge.

Exotisme religieux et bricolage

Cet article propose d’utiliser notion d’exotisme religieux afin d’analyser au mieux la dissémination des ressources religieuses « autres » dans les sociétés contemporaines et la relation que les acteurs sociaux entretiennent avec ces ressources. Il s’attachera aussi à montrer que cet outil conceptuel permet de reprendre les analyses qui ont été faites des bricolages composés de ressources symboliques variées, et en particulier d’en saisir les logiques culturelles et sociales. En effet, on a peut-être trop souvent surestimé l’éclectisme des combinaisons élaborées par les acteurs sociaux, pris pour acquise la disponibilité des ressources religieuses en présence et manqué de comprendre l’individualisme religieux de manière satisfaisante.

This article suggests that the notion of religious exoticism allows us to analyse better the diffusion of “other” religious resources in contemporary societies as well as the type of engagement individuals develop with the cultural and religious otherness. It will also try to show that this conceptual tool allows to further the analyzes that have been made about the forms of hybridity that combine diverse symbolic resources, and in particular to grasp its cultural and social logics. Indeed, the understanding of hybridity with foreign religions has sometimes over-estimated its eclecticism, taken for granted the availability of religious resources, and misunderstood religious individualism.

Faire parler les morts. Sur Jan Karski et la controverse Lanzmann-Haenel

The Second World War has inspired many French novelists since 1945. Yet, very few of these novels have been harshly criticized by either historians or other critics, Les Bienveillantes (2006) by Jonathan Littell and Jan Karski (2009) by Yannick Haenel being two notable exceptions. This article revisits the controversy between the novelist Yannick Haenel and the critic and film-maker Claude Lanzmann. First, it shows that the important questions raised by Lanzmann are not void of ambiguity, notably because key terms at the heart of this controversy (truth, fiction or even history) were used loosely. Second, this article compares the documentary Le Rapport Karski (2010) to other texts written by Karski and to the full transcription of the interview he gave to Lanzmann in 1978: it shows how Lanzmann's 2010 documentary distorts Karski's testimony to make it comply with historical perspectives that most historians would agree with today. Finally, the author of this article regrets that this controversy did not allow the debate to move beyond the military non-intervention of the Allies.

Asymmetric Total Synthesis of (+)-Inthomycin C Via O-Directed Free Radical Alkyne Hydrostannation with Ph3SnH and Catalytic Et3B: Reinstatement of the Zeeck-Taylor (3R)-Structure for (+)-Inthomycin C

A new pathway to (+)-inthomycin C is reported that exploits an O-directed free radical hydrostannation reaction on (−)-12 and a Stille cross-coupling as key steps. Significantly, the latter process was effected on 19 where a gauche-pentane repulsive interaction could interfere. Our stereochemical studies on the alkynol (−)-12 and the enyne (+)-7 confirm that Ryu and Hatakeyama’s (3S)-stereochemical revision of (+)-inthomycin C is invalid and that Zeeck and Taylor’s original (3R)-stereostructure for (+)-inthomycin C is correct.

Synthesis of the C(7)-C(22)-Sector of (+)-Acutiphycin Via O-Directed Double Free Radical Alkyne Hydrostannation with Ph3SnH/Et3B, Double I-Sn Exchange and Double Stille Coupling

Abstract Image

Herein a new double O-directed free radical hydrostannation reaction is reported on the structurally complex dialkyldiyne 11. Through our use of a conformation-restraining acetal to help prevent stereocenter-compromising 1,5-H-atom abstraction reactions by vinyl radical intermediates, the two vinylstannanes of 10 were concurrently constructed with high stereocontrol using Ph3SnH/Et3B/O2. Distannane 10 was thereafter elaborated into the bis-vinyl iodide 9 via O-silylation and double I–Sn exchange; double Stille coupling of 9, O-desilylation, and oxidation thereafter furnished 8.
