Die Methode der Kontingenzanalyse: eine Anwendung auf die Qualität der Küstengewässer,
von François Bonnieux, Philippe Le Goffe, Dominique Vermesch.

Es wird an den historischen Kontext erinnert, in dem die Méthode der Kontingenzanalyse entwickelt wurde, wobei die treibende Kraft der Nachfrage durch die Behörden sowie der Aktionen gegen die Verantwortlichen von Umweltschäden hervorgehoben wird. Die Anwendung dieser Méthode wird zunächst in einem allgemeinen Rahmen diskutiert, wobei das Interesse dem Begriff des hypothetischen Szenarios mit den sich daraus ergebenden Verzerrungen und den Techniken der Präferenzoffenbarungen gilt. Danach wird die Méthode anhand einer Fallstudie, und zwar über die Verbesserung der Qualität der Küstengewässer veranschaulicht. Hierbei stützt man sich auf das Beispiel der Reede von Brest und auf die Ergebnisse einer Erhebung, die bei 607 Personen im Sommer 1993 durchgeführt wurde. Zwei Szenarien werden untersucht; das erste betrifft die Verbesserung der Gewässerqualität und das zweite den Schutz des Ökosystems in der Reede vor der Eutrophierung. Mit der Zahlung eines Beitrages für die Gewässerqualität wären 75% der befragten Personen und für das Ökosystem 49% einverstanden. Für jedes Gut ist ein Tobit-Modell über die Zahlungsbereitschaft erstellt worden. Die bedeutendsten erklärenden Variablen sind das Geschlecht, das Einkommen, der Ausbildungsgrad oder der Beruf, die Sensibilität für Umweltfragen, die Einstellung gegenüber der Wasserqualität und das Betreiben von Freizeittätigkeiten.
Un lot céramique du Bas-Empire sur le site du Bivan (L'Albenc - Isère)
Authors: Ayala Grégoire 
Published: July 2011

L'analyse d'un lot céramique, provenant d'une fosse de rejet en marge d'un secteur de bâtiments du site du Bivan (Isère), a
permis d'offrir un «bon instantané» de la consommation d'un habitat au milieu du TV s. De cette analyse exhaustive du matériel (avec
traitement par fluorescence X d'échantillons de sigillée claire B et luisante en laboratoire), il ressort que l'approvisionnement s'effectuait
principalement à moyenne distance (Vallée du Rhône et Savoie).
Etablie sur des critères morphologiques et techniques, la méthode de traitement appliquée de manière expérimentale aux céramiques
communes a donné l'occasion d'aborder cette catégorie de mobilier, souvent largement majoritaire dans les lots céramiques mais cependant
mal connue et donc mal datée.
On espère ainsi amoindrir les lacunes relatives aux productions céramiques régionales durant la période tardive de l'Empire.
Familles transnationales et parents vieillissants à Chennai (Inde) : organisation des solidarités intergénérationnelles dans un espace intrafamilial mondialisé
Authors: Plard Mathilde 
Published: July 2011

Dans le contexte démographique actuel, le sud de l’Inde est marqué par un allongement de la durée de la vie et une augmentation significative des formes de mobilités internationales ; dans ces conditions, les relations intergénérationnelles évoluent. Si les migrations induisent des changements dans les mécanismes de transmission entre générations, elles modifient dans leurs formes les échanges familiaux et les solidarités intergénérationnelles. Une étude de terrain de type sociogéographique, effectuée dans la ville de Chennai en 2010 auprès de parents (de haute caste brahmane) dont les enfants ont migré vers des pays occidentaux, a permis d’étudier l’organisation des solidarités et de saisir les conséquences de la décohabitation entre génération, dans une nouvelle géographie familiale. Ces familles transnationales interrogent les modèles organisationnels de prise en charge et de solidarité concernant les personnes âgées vivant en dehors de l’idéal type de la joint family – la famille indivise .
Kafâla transnationale. Modalités de formation des familles kafilates de France
Authors: Barraud Émilie 
Published: July 2011

Cet article propose d’explorer un aspect méconnu de l’adoption internationale entre la France et les pays du Maghreb, et l’émergence en France d’une nouvelle catégorie de famille, dite « kafilate », dont l’origine est une famille élargie transnationale. Les familles kafilates de France se répartissent en deux grandes catégories. La première s’inscrit dans une logique d’adoption : un couple confronté à la stérilité, ou une femme seule, recueille légalement sous « kafâla » judiciaire un enfant abandonné au Maroc ou en Algérie. La seconde est basée sur le regroupement familial : des immigrés de France recueillent légalement sous « kafâla » notariale (au Maroc) ou judiciaire (en Algérie) un enfant de la famille. Après avoir présenté cette institution récente qu’est le recueil légal kafâla , l’article expose les causes et modalités de formation de ces nouveaux foyers, avant de se pencher sur les obstacles administratifs et juridiques que rencontrent ces familles, doublement marquées par le principe de « transnationalité ».
Medical Management of Osteonecrosis of the Hip: A Review
Authors: Rajpura Asim , Wright Andrew C. , Board Timothy N. 
Published: July 2011

Osteonecrosis or avascular necrosis (AVN) of the hip is a progressive disease mainly affecting adults in their third, fourth or fifth decade of life. Studies into the natural history of the disease suggest that femoral head collapse occurs within 2–3yrs with associated degenerative changes and at that stage arthroplasty is the most reliable treatment option. Therefore prevention of femoral head collapse is highly desirable in this young patient group. In early stage disease, before femoral head collapse (Ficat and Arlet stage 1–3) core decompression of the femoral head is currently the most widely used procedure to try to relieve intraosseous pressure in the femoral head and restore blood supply. Greater understanding of the pathogenesis of osteonecrosis has led to research into non-surgical management of early stages of the disease, including pharmacological and biophysical treatments. There may be a reduction in symptoms and evidence of prevention of disease progression following some non-surgical treatments. Further studies are needed, including trials comparing medical management with surgical intervention.

AbstractPhotothermal elastomers are recognized as smart flexible materials that can rapidly and effectively convert light energy into heat energy. However, there has been a lack of adequate focus on tackling the sustainability challenges of photothermal elastomers, particularly in terms of material selection, the integration of complex functionalities, and final disposal. A fully bio‐derived photothermal elastomer (BPTE) produced through a simple and chemical‐free approach is introduced, utilizing alkali lignin, lipoic acid, and phytic acid as bio‐derived feedstocks. The BPTE exhibits an adaptive polymeric network crosslinked by dynamic covalent disulfide bonds and multiple hydrogen bonds, endowing it with dual‐mode photothermal conversion capability, robustness, stretchability, rapidly self‐healing property, hydrophobicity, swelling resistance, self‐adhesion, full recyclability, and degradability. The BPTE is further demonstrated as a next‐generation solution for photothermal generators, light‐driven actuators, photothermal antibacterial dressings, and photothermal fibers. The versatility of BPTE opens avenues for innovative smart devices and systems with significant potential in energy conversion, soft robotics, medical treatment, and smart clothing. With outstanding photothermal performances, full recyclability, and biodegradability, these fully bio‐based elastomers present an attractive prospect for the development of the advanced smart photothermal products.

AbstractVirion‐mediated outbreaks are imminent and despite rapid responses, continue to cause adverse symptoms and death. Therefore, tunable, sensitive, high‐throughput assays are needed to help diagnose future virion‐mediated outbreaks. Herein, it is developed a tunable in situ assay to selectively enrich virions and extracellular vesicles (EVs) and simultaneously detect antigens and nucleic acids at a single‐particle resolution. The Biochip Antigen and RNA Assay (BARA) enhanced sensitivities compared to quantitative reverse‐transcription polymerase chain reaction (qRT‐PCR), enabling the detection of virions in asymptomatic patients, genetic mutations in single virions, and enabling the continued long‐term expression of viral RNA in the EV‐enriched subpopulation in the plasma of patients with post‐acute sequelae of the coronavirus disease of 2019 (COVID‐19). BARA revealed highly accurate diagnoses of COVID‐19 by simultaneously detecting the spike glycoprotein and nucleocapsid‐encoding RNA in saliva and nasopharyngeal swab samples. Altogether, the single‐particle detection of antigens and viral RNA provides a tunable framework for the diagnosis, monitoring, and mutation screening of current and future outbreaks.

AbstractAnatomizing mixed‐phases, referring to analyzing the mixing profiles and quantifying the phases’ proportions in a material, which is of great significance in the genuine applications. Here, by using second‐harmonic generation (SHG) polarimetry and piezoresponse force microscopy (PFM) techniques, this work elucidates the contributions and distributions of two different symmetric phases mixed in an archetype monoaxial molecular ferroelectric, diisopropylammonium chloride (DIPACl). The two competing phases are preferred in thermodynamics or kinetic process respectively, and this work evidences the switching behavior between the two competing phases facilitated by an external electrical field as opposed to a heating process. This research contributes novel insights into phase engineering in the field of molecular ferroelectrics and is poised to serve as a potent analytical tool for subsequent applications.

AbstractCreating heterojunctions or composites by incorporating noble metals offers a remarkable means to modulate the electronic charge transfer and the nonlinear optical (NLO) properties in 2D transition metal dichalcogenides (TMDCs). The response of such 2D‐TMDC‐noble metal composites to femtosecond (fs) infrared (IR) and terahertz (THz) radiation, however, remains vastly unexplored. While the linear optical characteristics of a prototypical 2D‐TMDC, namely, MoSe2 nanosheets incorporated with noble metal (such as Au, Pt, and Ag) nanoparticles in the UV–Vis and the THz spectral range, the NLO characteristics are measured using a 70‐fs pulse at 800 nm excitation is investigated. The results demonstrate a clear reduction of band gap with the incorporation of noble metals in MoSe2, indicating an effective charge transfer mechanism at play. Notably, the MoSe2‐noble metal nanocomposites depicted a significant enhancement in the THz conductivities. In addition, a dramatic 4‐fold enhancement in the third‐order nonlinear coefficient and ≈2‐fold enhancement in the third‐order NLO susceptibility is achieved in MoSe2‐Ag nanocomposite. These results univocally suggest that the noble metal‐based composites with suitable charge transfer channels promote enhanced carrier mobilities and tunable electron transfer dynamics, making these hybrid materials promising candidates for optoelectronic applications both at IR and THz frequencies.

AbstractThis study reviews a variety of “bioeconomy approaches” (BAs) to assess their potential contribution to resilience in agricultural systems, focusing on benefits that can improve multi‐functionality regarding private and public goods. It is based on Meuwissen et al.'s framework to assess the resilience of farming systems. Drawing on literature and expert knowledge, this indicator framework is adapted to develop a new framework which is then applied to seven contrasting BAs (miscanthus, perennial flowering wild plant mixtures, permanent grassland, nutrient recycling, agrivoltaics, urban agriculture, and microalgae). The major outcomes are: 1) the extended indicator framework can help evaluate BAs for their potential to foster resilience in future agricultural systems, 2) all BAs are characterized by their ability to provide multiple private and public goods simultaneously, 3) the strongest contribution of BAs to public goods is their function in maintaining the good condition of natural resources and resource‐use efficiency, 4) all BAs can enhance resilience in agricultural systems by contributing diversity, multifunctionality, environmental sustainability, and autonomy, 5) the mitigation of potential drawbacks of BAs implementation requires ex‐ante assessment, favorable BAs combinations, and stakeholder involvement, 6) context‐specific analysis of each BAs is required to assess their qualitative and quantitative contribution to resilience.

AbstractPrognostication in acute pulmonary embolism (PE) requires reliable markers. While cellular indices such as neutrophil‐to‐lymphocyte ratio (NLR), platelet‐to‐lymphocyte ratio (PLR), and systemic immune‐inflammation index (SII) appear promising, their utility in PE prognostication needs further exploration. We utilized data from the RIETE registry and the Loyola University Medical Center (LUMC) to assess the prognostic value of NLR, PLR, and SII in acute PE, using logistic regression models. The primary outcome was 30‐day all‐cause mortality. We compared their prognostic value versus the simplified Pulmonary Embolism Severity Index (sPESI) alone. We included 10 085 patients from RIETE and 700 from the LUMC. Thirty‐day mortality rates were 4.6% and 8.3%, respectively. On multivariable analysis, an elevated NLR (>7.0) was associated with increased mortality (adjusted odds ratio [aOR]: 3.46; 95% CI: 2.60–4.60), outperforming the PLR > 220 (aOR: 2.36; 95% CI: 1.77–3.13), and SII > 1600 (aOR: 2.52; 95% CI: 1.90–3.33). The c‐statistic for NLR in patients with low‐risk PE was 0.78 (95% CI: 0.69–0.86). Respective numbers were 0.66 (95% CI: 0.63–0.69) and 0.68 (95% CI: 0.59–0.76) for intermediate‐risk and high‐risk patients. These findings were mirrored in the LUMC cohort. Among 9810 normotensive patients in RIETE, those scoring 0 points in sPESI and with an NLR ≤ 7.0 (35% of the population) displayed superior sensitivity (97.1%; 95% CI: 95.5–98.7) and negative predictive value (99.7%; 95% CI: 99.5–99.8) than sPESI alone (87.1%; 95% CI: 83.9–90.3, and 98.7%; 95% CI: 98.4–99.1, respectively) for 30‐day mortality. The NLR is a significant prognostic marker for 30‐day mortality in PE patients, especially useful to identify patients with very low‐risk PE.

AbstractTo eliminate infected and cancerous cells, antigen processing and presentation play a pivotal role through the recognition of antigenic peptides displayed on Major Histocompatibility Complex class I (MHC I) molecules. Here, we developed a photostimulated antigen release system that enables the temporal inception of antigen flux. Simple and effective photocaging of the human immunodeficiency virus (HIV)‐Nef73‐derived epitope, a representative high‐affinity MHC I ligand, was provided by steric hindrance to block the recognition by the transporter associated with antigen processing (TAP) in the peptide loading complex (PLC). In response to light, a heteronomous release of antigens and subsequent translocation in various scenarios is demonstrated, including a TAP‐related ATP‐binding cassette (ABC) transporter reconstituted in liposomes and the native PLC in the endoplasmic reticulum (ER) membrane of human cells. The photochemically induced ‘burst’ of antigens opens new opportunities for a mechanistic analysis of the antigen translocation machinery and will help to provide insights into antigen processing pathways via an on‐demand, subcellular pulse‐chase release of antigens.

AbstractDispersion of single atoms (SAs) in the host is important for optimizing catalytic activity. Herein, we propose a novel strategy to tune oxygen vacancies in CeO2−X directionally anchoring the single atom platinum (PtSA), which is uniformly dispersed on the rGO. The catalyst's performance for the hydrogen evolution reaction (HER) can be enhanced by controlling different densities of CeO2‐X in rGO. The PtSA performs best optimally densified and loaded on homogeneous and moderately densified CeO2‐X/rGO (PtSA−M−CeO2−X/rGO). It exhibited higher activity in HER with an overpotential of 25 mV at 0.5 M H2SO4 and 33 mV at 1 KOH than that of almost reported electrocatalysts. Furthermore, it exhibited stability for 90 hours at −100 mA cm−2 in 1 KOH and −150 mA cm−2 in 0.5 M H2SO4 conditions, respectively. Through comprehensive experiments and theoretical calculations, the suitable dispersion density of PtSA on the defects of CeO2−X with more active sites gives the potential for practical applications. This research paves the way for developing single‐atom catalysts with exceptional catalytic activity and stability, holding promise in advanced green energy conversion through defects engineering.

AbstractEutectic electrolytes show potential beyond conventional low‐concentration electrolytes (LCEs) in zinc (Zn)‐ion capacitors (ZICs) yet suffer from high viscosity and sluggish kinetics. Herein, we originally propose a universal theory of intrinsically decoupling to address these issues, producing a novel electrolyte termed “quasi‐eutectic” electrolyte (quasi‐EE). Joint experimental and theoretical analyses confirm its unique solution coordination structure doped with near‐LCE domains. This enables the quasi‐EE well inherit the advanced properties at deep‐eutectic states while provide facilitated kinetics as well as lower energy barriers via a vehicle/hopping‐hybridized charge transfer mechanism. Consequently, a homogeneous electroplating pattern with much enhanced Sand's time is achieved on the Zn surface, followed by a twofold prolonged service‐life with drastically reduced concentration polarization. More encouragingly, the quasi‐EE also delivers increased capacitance output in ZICs, which is elevated by 12.4 %–144.6 % compared to that before decoupling. Furthermore, the pouch cell with a cathodic mass loading of 36.6 mg cm−2 maintains competitive cycling performances over 600 cycles, far exceeding other Zn‐based counterparts. This work offers fresh insights into eutectic decoupling and beyond.

AbstractBridged cyclobutanes and sulfur heterocycles are currently under intense investigation as building blocks for pharmaceutical drug design. Two formal cycloaddition modes involving bicyclobutanes (BCBs) and pyridinium 1,4‐zwitterionic thiolate derivatives were described to rapidly expand the chemical space of sulfur‐containing bridged cyclobutanes. By using Ni(ClO4)2 as the catalyst, an uncommon higher‐order (5+3) cycloaddition of BCBs with quinolinium 1,4‐zwitterionic thiolate was achieved with broad substrate scope under mild reaction conditions. Furthermore, the first Lewis acid‐catalyzed asymmetric polar (5+3) cycloaddition of BCB with pyridazinium 1,4‐zwitterionic thiolate was accomplished. In contrast, pyridinium 1,4‐zwitterionic thiolates undergo an Sc(OTf)3‐catalyzed formal (3+3) reaction with BCBs to generate thia‐norpinene products, which represent the initial instance of synthesizing 2‐thiabicyclo[3.1.1]heptanes (thia‐BCHeps) from BCBs. Moreover, we have successfully used this (3+3) protocol to rapidly prepare thia‐BCHeps‐substituted analogues of the bioactive molecule Pitofenone. Density functional theory (DFT) computations imply that kinetic factors govern the (5+3) cycloaddition reaction between BCB and quinolinium 1,4‐zwitterionic thiolate, whereas the (3+3) reaction involving pyridinium 1,4‐zwitterionic thiolates is under thermodynamic control.
