Mental health is a significant public health challenge globally, and one anticipated to increase following the COVID-19 pandemic. In many rural regions of developing nations, little is known about the prevalence of mental health conditions and factors that may help mitigate poor outcomes. This study assessed the impact of the COVID-19 pandemic on mental health and social support for residents of rural Haiti. Data were collected from March to May 2020. The Patient Health Questionnaire subscales for anxiety and depression, and the Perceived Stress Scale were utilized in addition to tailored questions specific to COVID-19 knowledge. Half (51.8%) of the 500 survey respondents reported COVID-19-related anxiety and worrying either daily or across a few days. Half (50.2%) also reported experiencing depression daily or across several days. Most (70.4%) did not have any social support, and 28.0% experienced some stress, with 13.4% indicating high perceived stress. Furthermore, 4.6% had suitable plumbing systems in their homes. The results were immediately actionable, informing the implementation of a mental health counseling program for youth following a loss of social support through school closures. Long-term investments must be made as part of public health responses in rural communities in developing nations, which remain under-studied.

We present new data from the debris-rich basal ice layers of the NEEM ice core (NW Greenland). Using mineralogical observations, SEM imagery, geochemical data from silicates (meteoric 10Be, εNd, 87Sr/86Sr) and organic material (C/N, δ13C), we characterize the source material, succession of previous glaciations and deglaciations and the paleoecological conditions during ice-free episodes. Meteoric 10Be data and grain features indicate that the ice sheet interacted with paleosols and eroded fresh bedrock, leading to mixing in these debris-rich ice layers. Our analysis also identifies four successive stages in NW Greenland: (1) initial preglacial conditions, (2) glacial advance 1, (3) glacial retreat and interglacial conditions and (4) glacial advance 2 (current ice-sheet development). C/N and δ13C data suggest that deglacial environments favored the development of tundra and taiga ecosystems. These two successive glacial fluctuations observed at NEEM are consistent with those identified from the Camp Century core basal sediments over the last 3 Ma. Further inland, GRIP and GISP2 summit sites have remained glaciated more continuously than the western margin, with less intense ice-substratum interactions than those observed at NEEM.

Cet article porte sur le débat idéologique que suscite l'interculturalisme dans le champ intellectuel québécois depuis les années 2000. S'il a longtemps servi de point de convergence entre intellectuel.le.s néonationalistes, cherchant à allier pluralisme et nationalisme, l'interculturalisme n'a toutefois pas empêché la recrudescence des appels en faveur du resserrement du contrôle sur les personnes migrantes et les pratiques culturelles minoritaires. Notre thèse est que cette tendance confirme l’éclipse de la tentative de concilier nationalisme et pluralisme au sein de l'interculturalisme québécois. Pour soutenir cette thèse, notre article documente la faiblesse de l'interculturalisme québécois devant les blocs idéologiques formés par le multiculturalisme fédéral, le nationalisme conservateur et la montée des critiques antiracistes et décoloniales au Québec. Face à ces positions rivales, les contradictions de l'interculturalisme quant au privilège de la majorité sur les minorités ont été mises au jour au fil de controverses que l'article examine sur une période de vingt ans.

Large frugivores provide critical seed dispersal services for many plant species and their extirpation from forested ecosystems can cause compositional shifts in regenerating plant cohorts. Yet, we still poorly understand whether large seed-dispersers have complementary or redundant roles for forest regeneration. Here, to assess the functional complementarity of large-bodied frugivores in forest regeneration, we quantified the effects of varying abundance of hornbills, primates and the forest elephant on the density, species richness and the mean weighted seed length of animal-dispersed tree species among seedlings in five sites in a forest–savanna mosaic in D. R. Congo, while accounting for percentage forest cover and the local presence of fruiting trees. We found that the abundance of primates was positively associated with species richness of seedlings, while percentage forest cover was negatively associated (R2 = 0.19). The abundance of hornbills, the presence of elephants and percentage forest cover were positively associated with mean seed length of the regenerating cohort (R2 = 0.13). Spatially explicit analysis indicated that some additional processes have an important influence on these response indices. Primates would seem to have a preponderant role for maintaining relatively high species richness, while hornbills and elephant would seem to be predominantly responsible for the recruitment of large-seeded trees. Our results could indicate that these taxa of frugivores play complementary functional roles for forest regeneration. This suggests that the extirpation of one or more of these dispersers would likely not be functionally compensated for by the remaining taxa, hence possibly cascading into compositional shifts.

Introduction
Application of a tourniquet is the cornerstone in management of combat-related extremity hemorrhages. Continuous and appropriate training is required to use tourniquets correctly.
HypothesisThe aim of this study was to analyze the impact of a refresher training session, conducted directly in the theater of military operations, on the performance of tourniquet use.
MethodsDuring their deployment (October 2015-April 2016) in the Central African Republic, a first simulation session evaluated soldiers from two combats platoons for the application of the SOFFT (Special Operation Forces Tactical Tourniquet; Tactical Medical Solutions; Anderson, South California USA) tourniquet. After randomization, a R (+) group underwent a refresher training session, while a R (−) group did not. Two months later, a second simulation session was conducted for both groups: R (+) and R (−). A dedicated score (one to seven points), including delay and effectiveness, evaluated the soldiers’ performance for tourniquet application.
ResultsTwenty-six subjects were included in the R (+) group and 24 in the R (−) group. Between the two assessments, the score improved for 61.5% of subjects of the R (+) group and 37.5% subjects of the R (−) group (P=.09). More particularly, the performance score increased from 4.2 (SD=1.4) to 5.5 (SD=0.9; P=.002) in subjects of the R (+) group whose last training for tourniquet application was over six months prior.
ConclusionA refresher tourniquet training session, conducted directly in a combat zone, is especially effective for soldiers whose last training session was over six months prior. A dedicated score can assess appropriately the performance of tourniquet training.

Soil CO2 flux measurement is a key method that can be used to monitor the hazards in an active volcanic area. In order to determine accurately the variations of the CO2 soil emission we propose an approach based on the radiocarbon (14C) deficiency recorded in the plants grown in and around the Solfatara (Naples, Italy). We twice sampled selected poaceae plants in 17 defined sites around the Solfatara volcano. 14C measurements by liquid scintillation counting (LSC) were achieved on the grass samples. The 14C deficiency determined in the sampled plants, compared to the atmosphere 14C activity, ranged from 6.6 to 51.6%. We then compared the proportion of magmatic CO2 inferred to the instantaneous measurements of CO2 fluxes from soil performed by the accumulation chamber CO2 degassing measurement at the moment of the sampling at each site. The results show a clear correlation (r=0.88) between soil CO2 fluxes and 14C activity. The determination of the plants 14C deficiency provides an estimate of the CO2 rate within a few square meters, integrating CO2 soil degassing variations and meteorological incidences over a few months. It can therefore become an efficient bio-sensor and can be used as a proxy to cartography of the soil CO2 and to determine its variations through time

Summary
To forecast the evolution of the sea ice cover in a particular region over a certain period of time, an automated prediction system must have a sea ice model. To produce these forecasts, a sea ice model requires information about the initial sea ice conditions and the atmospheric and oceanic forcing that largely govern the evolution of sea ice. The goal of this chapter is to describe how dynamics and thermodynamics processes are represented in large-scale continuum-based sea ice models. The physical processes presented include the transfer of momentum at the ice interfaces, sea ice rheology, transport, ridging, lateral melt and vertical growth and melt. This chapter also introduces how the equations for dynamics and thermodynamics are typically implemented and solved numerically. Recent model developements such as wave-ice interactions, salt dynamics and melt pond modelling are also discussed.

Local glacial fluctuations and flood occurrences were investigated in the sediment sequence of proglacial Lake Muzelle. Based on geochemical analysis and organic matter content established using loss on ignition and reflectance spectroscopy, we identified six periods of increased glacial activity over the last 1700 yr. Each is in accordance with records from reference glaciers in the Alps. A total of 255 graded layers were identified and interpreted as flood deposits. Most of these occurred during glacial advances such as the Little Ice Age period and exhibit thicker deposits characterized by an increase in the fine grain-size fraction. Fine sediment produced by glacial activity is transported to the proglacial lake during heavy rainfall events. The excess of glacial flour during these periods seems to increase the watershed’s tendency to produce flood deposits in the lake sediment, suggesting a strong influence of the glacier on flood reconstruction records. Thus, both flood frequency and intensity, which is estimated based on layer thickness as a proxy, cannot be used in reconstruction of past extreme events because of their variability. There is a need to take into account changes in sediment supply in proglacial areas that could preclude satisfactory interpretation of floods in terms of past climate variability.

Background: Using a population-based register of the Saguenay-Lac-Saint-Jean region (Quebec, Canada), the genealogical reconstruction of 533 individuals with intracranial aneurysm (IA) showed a familial aggregation (the presence of aneurysm in two or more first- to third-degree relatives) for 159 (29.8%) of them; this proportion is much higher than reported elsewhere. Objective: As part of an ongoing project to assess a genetic predisposition to intracranial aneurysms in the Saguenay-Lac-Saint-Jean population, the objective of the present study was to determine whether age-specific rates of ruptured cerebral aneurysms were higher than in other populations. Design: A retrospective study of cases of proven ruptured I As which were hospitalized during the 1973 to 1992 period was conducted. Age-adjusted rates were computed and compared to those reported in the Helsinki population. Results: We identified 412 cases of ruptured aneurysms. The age-adjusted incidence rate was 7.2/100,000/year (6.2 for men, 8.1 for women), which is similar to the incidence rates reported in other studies. Although the mean age at time of rupture was younger (46.6 years ± 13.8) than usually reported, no increase in age-specific incidence rates was detected. Conclusions: The results of this epidemiological study neither support nor reject the hypothesis of a genetic predisposition to intracranial aneurysms in the Saguenay-Lac-Saint-Jean population.

BACKGROUND
Reducing the spread of multidrug-resistant bacteria in hospitals remains a challenge. Current methods are screening of patients, isolation, and adherence to hygiene measures among healthcare workers (HCWs). More specific measures could rely on a better characterization of the contacts at risk of dissemination.
OBJECTIVETo quantify how close-proximity interactions (CPIs) affected Staphylococcus aureus dissemination.
DESIGNNested case-control study.
SETTINGFrench long-term care facility in 2009.
PARTICIPANTSPatients (n=329) and HCWs (n=261).
METHODSWe recorded CPIs using electronic devices together with S. aureus nasal carriage during 4 months in all participants. Cases consisted of patients showing incident S. aureus colonization and were paired to 8 control patients who did not exhibit incident colonization at the same date. Conditional logistic regression was used to quantify associations between incidence and exposure to demographic, network, and carriage covariables.
RESULTSThe local structure of contacts informed on methicillin-resistant S. aureus (MRSA) carriage acquisition: CPIs with more HCWs were associated with incident MRSA colonization in patients (odds ratio [OR], 1.10 [95% CI, 1.04–1.17] for 1 more HCW), as well as longer CPI durations (1.03 [1.01–1.06] for a 1-hour increase). Joint analysis of carriage and contacts showed increased carriage acquisition in case of CPI with another colonized individual (OR, 1.55 [1.14–2.11] for 1 more HCW). Global network measurements did not capture associations between contacts and carriage.
CONCLUSIONSElectronically recorded CPIs inform on the risk of MRSA carriage, warranting more study of in-hospital contact networks to design targeted intervention strategies.

In France, nuclear glass canisters arising from spent fuel reprocessing are expected to be disposed in a deep geological repository using a multi-barrier concept (glass/canister/steel overpack and claystone). In this context, glass - iron or corrosion products interactions were investigated in a clayey environment to better understand the mechanisms and driving forces controlling the glass alteration. Integrated experiments involving glass - metallic iron or magnetite - clay stacks were run at laboratory scale in anoxic conditions for two years. The interfaces were characterized by a multiscale approach using SEM, TEM, EDX and STXM at the SLS Synchrotron. Characterization of glass alteration patterns on cross sections revealed various morphologies or microstructures and an increase of the glass alteration with the proximity between the glass and the source of iron (metallic iron or magnetite) due to the consumption of the silica coming from the glass alteration. In case of magnetite, the silica consumption is mainly driven by a sorption of silica onto the magnetite. For experiments containing metallic iron, the silica consumption seems to be strongly driven by silicates precipitation including Fe and Fe/Mg when the Fe is not enough available. Moreover, in addition to Fe-silicates observed at the surface of the gel layers, iron is incorporated within the gel probably as nanosized precipitates of Fe-silicates which could affect its physical and chemical properties. Those results highlighted the impact of the distance between glass and iron source and the nature of the iron source which drive the process consuming the silica coming from the glass alteration.

Summary
This chapter presents an intercontinental comparison of studies on bird–habitat relationships in three types of cultural landscapes: those created by forestry (managed forests), agriculture (farmed land and remnant native habitats in a matrix of farmed land) and urbanisation. The geographical emphasis is on temperate and boreal regions of eastern Canada (hereafter referred to as ‘North America’) and western Europe/Fennoscandia. We seek out differences and similarities in patterns and discuss responses of birds to processes of landscape change. We consider the influence of human perception of landscapes on the development of research ideas and the extent to which there has been intercontinental exchange and application of ideas and research findings.
One of the most striking differences in the history of habitats in North America and Europe often put forward is the timing and rate of land clearing. The clearing of a predominantly forested landscape has often been described as one of the major tasks European settlers faced arriving in North America (Whitney, 1994), whereas in Europe land clearing had started around 6000 years ago (Williams, 2003).
However, the common picture of eastern North America as a vast forested wilderness before European colonisation is coming into question. Aboriginal people probably managed the landscape quite extensively through permanent or shifting agriculture and the use of fire to clear land for cultivation, to create parklands favourable to game and to open forest understorey to facilitate travel (Williams, 2003, 2008). These managed landscapes disappeared with the annihilation of over 90% of aboriginal populations starting in the 1500s, mainly due to diseases transmitted by Europeans. In southern Ontario, for instance, the extent of forested lands probably reached a low just before these epidemics (Pyne, 1982; Williams, 1989).

Objective:
Depression is a frequent problem in cancer patients, which is known to reduce quality of life; however, many cancer patients with depression are not treated because of the difficulties in assessing depression in this population. Our aim was to evaluate and improve the depression assessment strategies of palliative care (PC) physicians and oncologists.
Method:We invited all medical oncologists and PC physicians from three cancer centers to participate in this multicenter prospective study. They were asked to classify 22 symptoms (related and specific to depression in cancer patients, related but not specific, and unrelated) as “very important,” “important,” “less important,” or “not important” for the diagnosis of depression in cancer patients, at three different time points (at baseline, after a video education program, and after 4 weeks). They were also asked to complete a questionnaire exploring physicians' perceptions of depression and of their role in its systematic screening.
Results:All 34 eligible physicians participated. Baseline performance was good, with >70% of participants correctly classifying at least seven of nine related and specific symptoms. We found no significant improvement in scores in the immediate and 4-week follow-up tests. Additionally, 24 (83%) and 23 (79%) participants expressed support for systematic depression screening and a role for oncologists in screening, respectively.
Significance of results:Oncologists had good baseline knowledge about depression's main symptoms in cancer patients and a positive attitude toward being involved in screening. Underdiagnosis of depression is probably related to problems associated with the oncology working environment rather than the physicians' knowledge.

Investigation of Lake Allos sediments revealed ~ 160 graded layers, interpreted as flood deposits, over the last 1400 yr. Comparisons with records of historic floods support the interpretation of flood deposits and suggest that most recorded flood events are the result of intense meso-scale precipitation events. As there is no evidence for any major changes in erosion processes in the catchment since the Medieval Warm Period (MWP), we interpret the Allos record in terms of repeated intense precipitation events over the last millennium, with a low flood frequency during the MWP and more frequent and more intense events during the Little Ice Age. This interpretation is consistent with the pattern of increasingly humid conditions in the northwestern Mediterranean region. This long-term trend is superimposed on high frequency oscillations that correlate with solar activity and autumnal North Atlantic Oscillation (NAO). Finally, a comparison of flood records across the northwestern Mediterranean region showed that intense precipitation events in Allos (east of the Rhône Valley) were out of phase with events in the Cévennes (west of the Rhône) but in phase with events in eastern Spain. Supported by meteorological analyses, this suggests an oscillation in atmospheric circulation patterns over the northwestern Mediterranean.

Eating behaviour traits of rigid control and disinhibition have been associated with body weight in both adults and adolescents. Moreover, adults reporting a dieting history have increased levels of unhealthy eating behaviours. Against this background, the present study aimed to examine the relationship between dieting history and eating behaviour traits in adolescents. For the purpose of this research, a total of sixty adolescents (aged 15 (sem 2·4) years) from the Québec Family Study completed the Three-Factor Eating Questionnaire (TFEQ) and a questionnaire regarding eating habits. Self-reported current and past dieting were analysed against eating behaviour traits measured by the TFEQ, including all subscales. As the results revealed, few adolescents reported currently dieting (n 3). Adolescents who reported a dieting history (23·3 %) were older (16·9 v. 14·4 years, P < 0·001), were more likely to be female (78·6 v. 41·3 %, P < 0·05) but did not have a significantly higher BMI z-score (1·5 v. 0·9, P = 0·10), although they were more likely to be either overweight or obese (P < 0·01). After correcting for sex, BMI and age, adolescents who reported a dieting history had higher levels of rigid control and disinhibition (P < 0·05–0·0001) than those reporting no dieting history. A greater proportion of adolescents characterised by high rigid control and high disinhibition were past dieters, compared to those characterised by low levels of both behaviour traits (53 v. 4 %). The study arrived at the following conclusions: as observed in adults, adolescents with a history of dieting present unfavourable eating behaviour traits. These behavioural traits may represent an additional challenge to the long-term regulation of body weight.

Summary
Executive summary
Nature of the problem
The transfer of nitrogen by either farm management activities or natural processes (through the atmosphere and the hydrological network) can feed into the N cascade and lead to indirect and unexpected reactive nitrogen emissions.
This transfer can lead to large N deposition rates and impacts to sensitive ecosystems. It can also promote further N2O emission in areas where conditions are more favourable for denitrification.
In rural landscapes, the relevant scale is the scale where N is managed by farm activities and where environmental measures are applied.
Approaches
Mitigating nitrogen at landscape scale requires consideration of the interactions between natural and anthropogenic (i.e. farm management) processes.
Owing to the complex nature and spatial extent of rural landscapes, experimental assessments of reactive N flows at this scale are difficult and often incomplete. It should include measurement of N flows in the different compartments of the environment and comprehensive datasets on the environment (soils, hydrology, land use, etc.) and on farm management.
Modelling is the preferred tool to investigate the complex relationships between anthropogenic and natural processes at landscape scale although verification by measurements is required. Up to now, no model includes all the components of landscape scale N flows: farm functioning, short range atmospheric transfer, hydrology and ecosystem modelling.
