Quand le top-down rencontre le bottom-up : le paysage linguistique du comté autonome mongol de Henan (Sog po)
Authors: Wang Zixi 
Published: July 2024

Situé à cheval sur la frontière culturelle sino-tibétaine, le comté de Henan est un territoire aux multiples ethnies où, malgré sa reconnaissance comme « comté autonome mongol », la population autochtone, tant les Oïrats que les Tibétains pratiquent au quotidien le tibétain de l’Amdo comme langue véhiculaire. Le tibétain jouit encore d’une vitalité prédominante et d’une visibilité féconde dans ce comté frontalier, quoique l’arrivée accrue des peuples sinophones permet au chinois de devenir de plus en plus visible et audible, et ce surtout dans le bourg de Youganning, chef-lieu et centre économique du comté qui constitue le terrain de la présente recherche. S’appuyant sur une enquête conduite entre 2020 et 2021, le présent article s’attache à interroger la présence, l’usage et la visibilité des langues dans le paysage linguistique urbain du comté de Henan qui, à notre connaissance, n’a jamais fait l’objet d’une étude auparavant. Nous entendons ainsi contribuer à une compréhension profonde des rapports de force entre les langues et leurs locuteurs dans le contexte chinois.
On Working Memory Capacity and Implicit Associations between Advanced Age and Dangerous Driving Stereotypes
Authors: Lambert Ann E. , Seegmiller Janelle K. , Stefanucci Jeanine K. , Watson Jason M. 
Published: January 2013

SummaryDespite a large literature on implicit stereotypes, no one has scientifically documented the stereotype that older adults are dangerous drivers, even though its existence may impact older adults' driving performance through stereotype threat. The present studies are the first to use implicit tests to document the stereotype that older adult drivers are dangerous drivers. Experiment 1 (N = 159) documented a negative stereotype of older adult drivers in young and older adults by using a novel driving and age Implicit Association Test (IAT). Experiment 2 (N = 216) demonstrated that individual differences in working memory capacity moderate the degree to which young adults can willfully change this IAT score such that higher working memory capacity was associated with greater control of this negative stereotype of age and driving. This finding illustrates the potential utility of working memory capacity in interventions designed to reduce the impact of implicit stereotypes and negative attitudes.

From the mouths of babes: Dental caries in infants and children and the intensification of agriculture in mainland Southeast Asia

Published: January 2013

AbstractMany bioarchaeological studies have established a link between increased dental caries prevalence and the intensification of agriculture. However, research in Southeast Asia challenges the global application of this theory. Although often overlooked, dental health of infants and children can provide a sensitive source of information concerning health and subsistence change. This article investigates the prevalence and location of caries in the dentition of infants and children (less than 15 years of age) from eight prehistoric mainland Southeast Asian sites collectively spanning the Neolithic to late Iron Age, during which time rice agriculture became an increasingly important subsistence mode. Caries prevalence varied among the sites but there was no correlation with chronological change. The absence of evidence of a decline in dental health over time can be attributed to the relative noncariogenicity of rice and retention of broad‐spectrum subsistence strategies. No differences in caries type indicating differences in dental health were found between the sites, apart from the Iron Age site of Muang Sema. There was a higher prevalence of caries in the deciduous dentition than the permanent dentition, likely due to a cariogenic weaning diet and the higher sensitivity of deciduous teeth to decay. The level of caries in the permanent dentition suggests an increased reliance on less cariogenic foods during childhood, including rice. The absence of a temporal decline in dental health of infants and children strengthens the argument that the relationship between caries and agricultural intensification in Southeast Asia was more complex than the general model suggests.

AbstractMany lemur species are arboreal, elusive, and/or nocturnal and are consequently difficult to approach, observe and catch. In addition, most of them are endangered. For these reasons, non‐invasive sampling is especially useful in primates including lemurs. A key issue in conservation and ecological studies is to identify the sex of the sampled individuals to investigate sex‐biased dispersal, parentage, social organization and population sex ratio. Several molecular tests of sex are available in apes and monkeys, but only a handful of them work in the lemuriform clade. Among these tests, the coamplification of the SRY gene with the amelogenin X gene using strepsirhine‐specific X primers seems particularly promising, but the reliability and validity of this sexing test have not been properly assessed yet. In this study, we (i) show that this molecular sexing test works on three additional lemur species (Microcebus tavaratra, Propithecus coronatus and P. verreauxi) from two previously untested genera and one previously untested family, suggesting that these markers are likely to be universal among lemurs and other strepsirrhines; (ii) provide the first evidence that this PCR‐based sexing test works on degraded DNA obtained from noninvasive samples; (iii) validate the approach using a large number of known‐sex individuals and a multiple‐tubes approach, and show that mismatches between the field sex and the final molecular consensus sex occur in less than 10% of all the samples and that most of these mismatches were likely linked to incorrect sex determinations in the field rather than genotyping errors.

ObjectiveCerebral microbleeds (CMBs) are a neuroimaging marker of small vessel disease (SVD) with relevance for understanding disease mechanisms in cerebrovascular disease, cognitive impairment, and normal aging. It is hypothesized that lobar CMBs are due to cerebral amyloid angiopathy (CAA) and deep CMBs are due to subcortical ischemic SVD. We tested this hypothesis using structural magnetic resonance imaging (MRI) markers of subcortical SVD and in vivo imaging of amyloid in patients with cognitive impairment.MethodsWe included 226 patients: 89 with Alzheimer disease–related cognitive impairment (ADCI) and 137 with subcortical vascular cognitive impairment (SVCI). All subjects underwent amyloid imaging with [11C] Pittsburgh compound B (PiB) positron emission tomography, and MRI to detect CMBs and markers of subcortical SVD, including the volume of white matter hyperintensities (WMH) and the number of lacunes.ResultsParietal and occipital lobar CMBs counts were higher in PiB+ ADCI with moderate WMH than PiB+ ADCI with minimal WMH, whereas PiB− patients with SVCI (ie, “pure” SVCI) showed both lobar and deep CMBs. In multivariate analyses of the whole cohort, WMH volume and lacuna counts were positively associated with both lobar and deep CMBs, whereas amyloid burden (PiB) was only associated with lobar CMBs. There was an interaction between lacuna burden and PiB retention on lobar (but not deep) CMBs (p<0.001).InterpretationOur findings suggest that although deep CMBs are mainly linked to subcortical SVD, both subcortical SVD and amyloid‐related pathologies (eg, CAA) contribute to the pathogenesis of lobar CMBs, at least in subjects with mixed lobar and deep CMBs. Furthermore, subcortical SVD and amyloid‐related pathologies interact to increase the risk of lobar CMBs. Ann Neurol 2013;73:584–593
Seed‐Mediated Synthesis of Single‐Crystal Gold Nanospheres with Controlled Diameters in the Range 5–30 nm and their Self‐Assembly upon Dilution

Published: January 2013

AbstractSingle‐crystal gold nanospheres with controlled diameters in the range 5–30 nm were synthesized by using a facile approach that was based on successive seed‐mediated growth. The key to the success of this synthesis was the use of hexadecyltrimethylammonium chloride (CTAC) as a capping agent and a large excess of ascorbic acid as a reductant to ensure fast reduction and, thus, single crystallinity and a spherical shape of the resultant nanoparticles. The diameters of the gold nanospheres could be readily controlled by varying the amount of seeds that were introduced into the reaction system. The gold nanospheres could be produced with uniform diameters of up to 30 nm; thus, their localized surface plasmon resonance properties could be directly compared with the results that were obtained from theoretical calculations. Interestingly, we also found that these gold nanospheres self‐assembled into dimers, larger aggregates, and wavy nanowires when they were collected by centrifugation, dispersed in deionized water, and then diluted to different volumes with deionized water.
Compliance boundaries for multiple‐frequency base station antennas in three directions

Published: January 2013

AbstractIn this article, compliance boundaries and allowed output powers are determined for the front, back, and side of multiple‐frequency base station antennas, based on the root‐mean‐squared electric field, the whole‐body averaged specific absorption rate (SAR), and the 10 g averaged SAR in both the limbs and the head and trunk. For this purpose, the basic restrictions and reference levels defined by the International Commission on Non‐Ionizing Radiation Protection (ICNIRP) for both the general public and occupational exposure are used. The antennas are designed for Global System for Mobile Communications around 900 MHz (GSM900), GSM1800, High Speed Packet Access (HSPA), and Long Term Evolution (LTE), and are operated with output powers at the individual frequencies up to 300 W. The compliance boundaries are estimated using finite‐difference time‐domain simulations with the Virtual Family Male and have been determined for three directions with respect to the antennas for 800, 900, 1800, and 2600 MHz. The reference levels are not always conservative when the radiating part of the antenna is small compared to the length of the body. Combined compliance distances, which ensure compliance with all reference levels and basic restrictions, have also been determined for each frequency. A method to determine a conservative estimation of compliance boundaries for multiple‐frequency (cumulative) exposure is introduced. Using the errors on the estimated allowed powers, an uncertainty analysis is carried out for the compliance distances. Uncertainties on the compliance distances are found to be smaller than 122%.

Evaluation of the effects of weak and moderate static magnetic fields on the characteristics of human low density lipoprotein in vitro

Published: January 2013

AbstractIt has been suggested that exposure to electromagnetic fields may be a risk factor for cardiovascular disease in humans. Low density lipoprotein (LDL) modifications such as peroxidation and aggregation have been implicated in the pathogenesis of atherosclerosis. The present study investigated the effects of weak (0.125–0.5 mT) and moderate (1–4 mT) static magnetic fields (SMFs) on LDL oxidation, aggregation and zeta potential in vitro. Our results demonstrated that magnetic flux densities of 0.25 and 0.5 mT decreased, and magnetic flux densities of 3 and 4 mT increased the zeta potential and LDL oxidation in comparison with the control samples. All doses of SMFs increased the LDL aggregation in a time‐ and dose‐dependent manner. It is concluded that SMFs can alter the susceptibility of LDL to oxidation and this alteration is dependent on the applied magnetic flux density. The SMF, in addition to its role in the production and stabilization of free radicals and promotion of lipid peroxidation, may influence the metabolism of lipoproteins and their interaction with other molecules such as apolipoproteins, enzymes and receptors through the alteration of the LDL zeta potential and its particles tendency to aggregation.

BackgroundPrevious studies failed to assess the individual prognostic role of thrombus aspiration (TA) or abciximab in primary percutaneous coronary intervention (pPCI), due their prevalent combined use.Methods and ResultsA total of 644 consecutive ST‐segment elevation myocardial infarction patients treated with pPCI were included in this retrospective registry from January 2006 to December 2008. Patients were divided in: (a) Group 1, with conventional pPCI; (b) Group 2, with pPCI and abciximab; (c) Group 3, with pPCI and TA; (d) Group 4, with pPCI and abciximab plus TA. Primary end point was the composite of major adverse cardiovascular events (MACEs, defined as overall mortality, myocardial infarction, target vessel revascularization, and major bleedings) at 1 year. Baseline clinical and angiographic characteristics were not different among the groups, with the exception of a younger age in group 4. The two groups of patients treated with TA (group 3 and 4) received more frequently direct stenting (P < 0.001 vs. group 1 for both), presented higher rate of end‐procedural TIMI flow grade 3 (P < 0.001 vs. group 1 for both), and lower rate of no‐reflow (P = 0.016 and P < 0.001 vs. group 1, respectively). Patients of group 2 presented a borderline nonsignificant trend toward higher rate of end‐procedural TIMI flow grade 3 (P = 0.083 vs. group 1). MACEs at 1 year were 43 (29%) in group 1 versus 25 (22%) in group 2 versus 24 (19%) in group 3 versus 32 (13%) in group 4 (log‐rank P = 0.001). At the multivariate Cox regression analysis, combined TA plus abciximab in group 4 [hazard ratio (HR): 0.48, confidence interval (CI) 95% 0.28–0.84, P = 0.01] and a higher left ventricular ejection fraction (HR: 0.97, CI 95% 0.95–0.98, P < 0.001) were significantly associated with lower MACE rate.ConclusionsThe combination of pharmacologic and mechanic antithrombotic treatment during pPCI was associated with better 1‐year clinical outcome. © 2013 Wiley Periodicals, Inc.
Revealing Unexpected Mechanisms for Nucleophilic Attack on SS and SeSe Bridges
Authors: Heverly‐Coulson Gavin S. , Boyd Russell J. , Mó Otilia , Yáñez Manuel 
Published: January 2013

AbstractThe reactivity of disulfide and diselenide derivatives towards F−and CN−nucleophiles has been investigated by means of B3PW91/6‐311+G(2df,p) calculations. This theoretical survey shows that these processes, in contrast with the generally accepted view of disulfide and diselenide linkages, do not always lead to SS or SeSe bond cleavage. In fact, SS or SeSe bond fission is the most favorable process only when the substituents attached to the S or the Se atoms are not very electronegative. Highly electronegative substituents (X) strongly favor SX bond fission. This significant difference in the observed reactivity patterns is directly related to the change in the nature of the LUMO orbital of the disulfide or diselenide derivative as the electronegativity of the substituents increases. For weakly electronegative substituents, the LUMO is a σ‐type SS (or SeSe) antibonding orbital, but as the electronegativity of the substituents increases the π‐type SX antibonding orbital stabilizes and becomes the LUMO. The observed reactivity also changes with the nature of the nucleophile and with the S or Se atom that undergoes the nucleophilic attack in asymmetric disulfides and diselenides. The activation strain model provides interesting insights into these processes. There are significant similarities between the reactivity of disulfides and diselenides, although some dissimilarities are also observed, usually related to the different interaction energies between the fragments produced in the fragmentation process.

Published: January 2013

AbstractExperiments were conducted to study the airborne microbial contamination generated by a wastewater treatment plant (WWTP). Aerosol samples were collected simultaneously, by sedimentation and impact methods, from the area and the surroundings of the WWTP. Total colony forming units (CFUs) of heterotrophic bacteria (HPC), as well as members of the Enterobacteriaceae, staphylococci, enterococci, actinomycetes, and microscopic fungi were determined. Bacterial (HPC) concentrations ranged between 101 and 104 CFU/m3, fungi 0 and 104 CFU/m3. Higher numbers of HPC bacteria in air samples were observed in summer, fungi in autumn. The main emission of microorganisms to atmospheric air was from the mechanical sewage treatment devices of the WWTP. The facilities of the biological sewage treatment of the plant did not generate large amounts of bioaerosols. In the air obtained from the premises of the WWTP, 25 species of the Enterobacteriaceae were isolated (Salmonella spp., Klebsiella pneumoniae, Escherichia coli). At the fence and in the surroundings only Pantoea spp. were identified. This suggests that the sewage bacteria were mainly discharged in the area of the WWTP. The presence of enteric bacteria, especially Enterobacteriaceae reflects the level of air pollution with bioaerosols from sewage and is an important factor during monitoring the quality of the air around WWTPs.
