In January 1999, Belgium encounters an accidental contamination of the food chain, which was named "the Belgian Dioxin Crisis". The aim of the present review is to estimate the impact of this crisis on public health. Currently, it does not really exist any exhaustive epidemiological study. Various scientific studies actually report somewhat conflicting results. As an example, concerning the population living in Wallonia, recorded dioxin levels are not higher than background levels reported for other industrialized countries, despite the 1999 "dioxin crisis". Conversely, based on levels measured in foodstuffs collected by the end of the crisis period, the dioxin body burden of potential consumers would have increased in the range of 40 to 75 %. The real impact of this crisis on consumers' health could thus only be estimated through well structured epidemiological campaigns. [less ▲]

Using lying deadwood or coarse woody debris (CWD) is on the rise among national and local forest inventories. We compared two generally recommended methods for lying deadwood: line intersect sampling and fixed area sampling. We assessed both methods in plots of the regional forest inventory of Wallonia (southern region of Belgium) and we developed bridging functions that converts CWD volume estimates to estimates that would have been obtained with different thresholds.

SESAME was an Integrated Project under the European Union's 6th Framework Programme. The project involved almost four hundred scientists from 59 research institutes in 24 countries, which included almost all countries of the Mediterranean and Black Sea Basins. This level of cooperation and coordination allowed data collection on different aspects of the Mediterranean and Black Sea ecosystems on a scale never before attempted. The project was designed to study the past, present and future environmental changes in the Southern European Seas (SES) ecosystems, as well as the effect of these changes on fundamental goods (tourism, fisheries) and services (mitigation of climate through carbon sequestration and ecosystem stability through conservation of biodiversity) provided by the ecosystems. The project's innovative character was reflected in the close merging of economic and natural sciences to study changes that occurred in the past 50 years and those that may occur in the next 50 years, through connecting ecological models with climatic and socio-economic scenarios.

Thanks to advances in medical care, an increased number of patients recover from coma. However, some remain in vegetative/unresponsive wakefulness syndrome or in a minimally conscious state. Detection of awareness in severely brain-injured patients is challenging because it relies on behavioral assessments, which can be affected by motor, sensory and cognitive impairments of the patients. Other means of evaluation are needed to improve the accuracy of the diagnosis in this challenging population. We will here review the different altered states of consciousness occurring after severe brain damage, and explain the difficulties associated with behavioral assessment of consciousness. We will then describe a non-invasive technique, transcranial magnetic stimulation combined with high-density electroencephalography (TMS-EEG), which has allowed us to detect the presence or absence of consciousness in different physiological, pathological and pharmacological states. Some potential underlying mechanisms of the loss of consciousness will then be discussed. In conclusion, TMS-EEG is highly promising in identifying markers of consciousness at the individual level and might be of great value for clinicians in the assessment of consciousness. [less ▲]

Deadwood plays an important role in forest ecological processes and is fundamental for the maintenance of biological diversity. Further, it is a forest carbon pool whose assessment must be reported for international agreements dealing with protection and forest management sustainability. Despite wide agreement on deadwood monitoring by national forest inventories (NFIs), much work is still necessary to clarify definitions so that estimates can be directly compared or aggregated for international reporting. There is an urgent need for an international consensus on definitions and agreement on harmonization methods. The study addresses two main objectives : to analyze the feasibility of harmonization procedures for deadwood estimates and to evaluate the impact of the harmonization process based on different definitions on final deadwood estimates. Results are reported for an experimental harmonization test using NFI deadwood data from 9,208 sample plots measured in nine European countries and the United States. Harmonization methods were investigated for volume by spatial position (lying or standing), decay classes, and woody species accompanied by accuracy assessments. Estimates of mean plot volume based on harmonized definitions with minimum length/height of 1 m and minimum diameter thresholds of 10, 12, and 20 cm were on average 3, 8, and 30% smaller, respectively, than estimates based on national definitions. Volumedifferences were less when estimated for various deadwood categories. An accuracy assessment demonstrated that, on average, the harmonization procedures did not substantially alter deadwood observations (root mean square error 23.17%). [less ▲]

We previously showed that low levels of day-14 CD3 T and NK (CD56) cells donor chimerism predicted graft rejection, whereas high levels of day-28 CD3 T-cell donor chimerism predicted acute graft-versus-host disease (GVHD) after HCT with nonmyeloablative conditioning. Here we investigate whether assessing chimerism levels among CD4 T cells and CD8 T cells, and also the absolute number of lymphocyte subsets of donor and host origins, would lend greater precision to our initial observations. We analyzed data from 157 patients receiving HCT after conditioning with 2 Gy TBI +/− fludarabine as treatment for AML (n= 22), ALL (n= 4), CML (n= 13), CLL (n= 19), MDS (n= 26), MM (n= 24), NHL (n= 30), HD (n= 14), RCC (n= 4), and WASP deficiency (n= 1). Postgrafting immunosuppression included MMF and CSP. A total of 97 patients received grafts from HLA-identical siblings, and 60 patients received grafts from HLA-matched unrelated donors. Lymphocyte subsets were isolated from peripheral blood by flow cytometry on days 14, 28, and 42. The proportion of cells of donor origin (chimerism levels) were assessed by VNTR-PCR and quantified by phosphor imaging. Eighteen patients (11%) had graft rejection. Day-14 donor chimerism levels< 50% among CD3 T (P =.0007), CD4 T (P =.03), and NK cells (P =.003) but not CD8 T cells predicted graft rejection. High absolute numbers of CD3 T (P =.002) and NK cells (P= .002) of host origin on day 14 were each associated with increased risks of graft rejection when treated as continuous linear variables. Grades 2, 3, and 4 acute GVHD were seen in 40%, 9%, and 5% of patients, respectively. High donor chimerism levels on day 14 among CD3 T (P= .02), CD4 T (P =.03), and CD8 T cells (P =.02) but not NK cells were each associated with increased risks of grades 2–4 acute GVHD. High absolute numbers of CD4 T (P =.04) and CD8 T cells (P =.04) of donor origin on days 14–42 were each associated with increased risks of grade 2–4 acute GVHD when treated as continuous linear variables, whereas high donor CD3 T (P= .002), CD8 T (P= .006), and NK cell (P= .002) chimerism levels from days 14–42 were associated with decreased risks of relapse. No statistically significant correlations between absolute numbers of donor cells and risks of relapse were found. These data suggest that assessing CD3, CD4, CD8, and NK cell donor chimerism levels and determining absolute numbers of CD3 and NK cells of host and donor origins are useful for predicting HCT outcomes after nonmyeloablative conditioning.

The link between resting­‐state functional connectivity (FC), measured by the correlations of the fMRI BOLD time courses, and structural connectivity (SC) has been repeatedly investigated recently. Meanwhile, the importance of considering the dynamics of neuronal processes has also been highlighted. In this work we show how the classical static (i.e. considered as constant) relationship between SC and FC could be enriched when the FC dynamics are taken into account. We use a sliding window approach to explore these dynamics and show that the window width should be chosen in a particular range in order to unveil statistically significant (i.e. not due to noise) fluctuations of the FC-­‐SC correlation.

How did Mexican migrants react to the opportunity to formally participate for the first time in home country politics during the 2006 Presidential Election? In this paper, we attempt to explain the low level of migrant voter registration in home country elections. Grounding ourselves on the existing literature on voter turnout, we verify two hypotheses that focus (1) on the role of Mexican authorities, and (2) on the interest of migrants and migrant associations in home country politics. Building on the case of Mexico, the paper concludes with proposing a series of variables upon which we suggest research could focus in order to assess migrant voter turnout in home country elections.

This study presents the validation results of a SJT developed in collaboration with a Belgian french speaking mutual insurance company for the assessment of employees OCB. The purpose is to provide empirical evidence concerning the validity of using the SJT by examining the issues of OCB criterion validity, incremental validity beyond a personality inventory, applicant perception and SJT transparency level. The SJT was developed in-house and following relevant literature recommendations (Weekley, Ployhart & Holtz, 2006). Data were collected on 117 white-collar employees. Three other measurements were concurrently collected: OCB using Williams & Anderson (1991) self-reported scales, personality using the Gosling, Rentfrow & Swann (2003) ten item inventory (TIPI) and applicant perception using SPJS (Bauer, & al., 2001). An open-ended question was used to access the extent to which applicants are able to identify the SJT criteria. Results indicated that the SJT is a relevant predictor of OCB (r = .42; p<.001). The SJT also provides incremental explanation of the OCB criteria beyond the personality inventory (∆R² = .11; p<.001). There was in average an agreement about the acceptability of the SJT in terms of perceived procedural justice. No relationships were found between applicant ability to correctly identify the SJT criteria and SJT score or OCB self-rating. This study is to our knowledge among the first attempt to develop and validate a tool to fill the gap on how to predict employees OCB (Organ, Podsakoff & Podsakoff, 2010). Implications for the personnel selection and current limitations will be discussed. [less ▲]
