This paper discusses the relevance of using physical situations to introduce the concept of angles at elementary school. We compare the effectiveness of two geometry teaching sequences. In the first one (physical sequence), the pupils learned the angle concept by experimenting on the playground (i.e. mesospace) and then modelling the situation. In the second one (paper-and-pencil sequence), the pupils worked solely in the space of a sheet of paper (i.e. microspace). In both sequences, pupils compared areas of space delineated by an angle between two directions. Pupils in two Grade 3 classes were exposed to one of the two teaching sequences. The unfolding of these sequences was videotaped and analyzed, and the pupils were tested individually, before and after teaching, to measure each sequence's effectiveness. Results showed that both sequences are effective to grasp the angle concept: Most pupils overcame the common erroneous conception of comparing angles' sides' lengths instead of angle openness. The comparison of areas of space delineated by an angle between two infinite directions, which is the two sequences' common core, seems to be the key factor underlying angle conceptualization. This paper ends with a discussion of these results' teaching implications and the merits of each sequence.

Schools are ideal settings to promote adolescent physical activity (PA), yet school-based interventions have shown limited long-term impact. This position paper presents key issues surrounding school-based PA interventions. Collaborative conceptual thinking drawing on multi-author expertise and available evidence advanced our understanding and opinion. Key arguments: 1) the adoption of a systems approach, which maximizes partnership action and leverages policy, is crucial for understanding the complexities of implementing whole-school programs; 2) a reorientation to an assets perspective optimizes existing strengths and resources allowing greater emphasis on the full range of physical, cognitive, emotional and social benefits that PA provides, and 3) a move beyond traditional positivist research designs to advance our knowledge of what works better, for whom and in what context is needed for greater progress We provide suggestions, specifically advocating for systems approaches, as a realistic way to improve how we support PA in schools in the future.

Introduction: Military operations are no longer limited to the application of counterterrorism and counterinsurgency strategies; they are now characterized by hybrid, irregular, and unconventional features. While some authors have indicated the need for medical support to adapt to these new modes of military operations, they have focused mainly on the tactical level of care on the battlefield. As Sun Tzu states, "Strategy without tactics is the slowest route to victory. Tactics without strategy is the noise before defeat," further proposals are still needed on the application of both medical tactics and medical strategies in irregular warfare., Methods: Medical experts from the French Special Operations Forces (SOF) Medical Command have identified specific medical challenges that special operations face in the context of the current transformation of armed confrontations into irregular warfare., Results: This position paper presents original tactical medical proposals for improving medical support in irregular warfare, ranging from the definition of a Primary-Alternate-Contingency-Emergency medical plan to the promotion of telemedical support. Original strategic medical proposals have highlighted the importance of recognizing medical issues in irregular warfare, including the medical actions carried out through and with local partners and the multiple approaches to countering medical threats., Conclusion: The SOF medical community must be closely involved with and facilitate the responses to the shift to irregular warfare. International collaboration and interoperability are more necessary than ever, as they will enable a more effective combination of good medicine with both good tactics and good strategies. These perspectives can also be extended to improve medical care in the conventional armed forces and austere civilian settings., Level of Evidence: Therapeutic/Care Management; Level V., (Copyright © 2024 The Author(s).

Low-density lipoprotein cholesterol has been established as a powerful cardiovascular risk factor; its reduction provides a clinical benefit in primary cardiovascular prevention, irrespective of the characteristics of the patients treated. It is useful to tailor low-density lipoprotein cholesterol targets according to the magnitude of cardiovascular risk (low, high or very high) in order to reduce the cardiovascular risk as fully as possible. In order to provide a uniform approach, it is necessary to propose recommendations for good practice, defining strategies for reducing low-density lipoprotein cholesterol. It is also necessary to know their merits, to analyse their practical limits and to propose adaptations, taking into account limitations and national specifics. This position paper aims to analyse the contribution and limits, as well as the adaptation to French practice, of 2019 and 2021 European Society of Cardiology recommendations for the management of lipid variables and cardiovascular prevention., (Copyright © 2024 Elsevier Masson SAS.

With the exception of the renowned Marquis de Lafayette and, to a lesser extent, General Rochambeau and Admiral de Grasse, French soldiers and officers have historically received little attention in the literary of the American War for Independence. This is due to a number of factors, including restricted or closed access to private archival collections in France. This essay will demonstrate that it is possible, under certain conditions, to study personal, unpublished source material of "forgotten" French officers who participated in the American Revolutionary War, thereby providing new opportunities for research into early American history. To demonstrate the historical significance of such materials, this paper will concentrate on the (mainly) unpublished papers of François-Jean de Chastellux (1734-1788), an influential major general who served directly under Rochambeau. The Chastellux family has preserved his private papers for more than 240 years in their Château de Chastellux. This article details the contents of this private archive as well as the history of its creation and preservation. Additionally, the existence of Chastellux's archive raises questions about the possible existence of similar unpublished French archival collections, which may also offer new perspectives on the American Revolutionary War. Furthermore, in the contemporary digital era, families that choose to preserve their records in private archives may now make them digitally accessible to the academic community. This introduces new circumstances and opportunities for the access and translation of previously inaccessible information. [ABSTRACT FROM AUTHOR]

This paper discusses key themes of the 15th biennial conference of the Association for Language Awareness (2020), with a focus on increasing digital engagement in language education. The COVID-19 pandemic occasioned an abrupt transition to emergency remote language teaching and learning (ERLTL) worldwide. The ALA 2020 conference was also affected by this transition; originally planned as a located conference in Geelong, Australia, it was eventually held online, a first in ALA's conference history. The current paper engages with contemporary debates of language teaching and learning in two ways. Firstly, it traces recent discussions by presenting key findings from five papers given at the conference, and secondly, via a scoping review of literature focusing on critical lessons from the pandemic regarding language teaching and learning. The review captures recent research from the Australasian region. Key debates identified in the literature include the needs of teachers and learners during the transition to online learning, and how student engagement was affected. The literatures highlight that both educators and students have been developing new practices in teaching and learning resulting from the shift to online and blended modes, which may continue to shape language education and new pedagogies in the future.

We analyze the role of institutional founding conditions and institutional legacy for universities' self-representation in terms of diversity. Based on 374 universities located in the Czech Republic, France, Germany, Hungary, Italy, and Poland, we can differentiate between a more idealistic understanding (logic of inclusion and equality) and a more market-oriented understanding (market logic) of diversity. Our findings show that the founding phase has no significant effect on the likelihood of a university focusing on a market-oriented understanding of diversity--however, we observe an imprinting effect with respect to the adoption of a diversity statement in general and an equity-oriented statement. Moreover, our findings show that there is a socialistic heritage for universities in Central and Eastern European (CEE) countries that is at work and still influences universities' understandings of diversity today.

The paper provides empirical results on the part of grey literature in the French national open repository HAL. The results are based on a quantitative analysis of 973,968 deposits from 1,272 research laboratories affiliated the ten most important research universities in France (IDEX program). 35% of all deposits (documents and records) are grey literature. The main types of these items are conference papers (71%), PhD theses (11%) and preprints and working papers (8%). Their overall accessibility (degree of openness) is 37%, which is higher than commercial publications. Differences between document types, disciplines and institution are described. Further research is needed for a better understanding of how research laboratories are handling grey literature (licensing ...). A follow-up study in 2021 will provide this insight.

(1) Background: The main basis for the public recognition of the merits of scientists has always been the system of scientific publications and citations. Our goal is to identify and analyze the most cited articles in the Public, Environmental & Occupational Health category. (2) Methods: We searched the Web of Science for all articles published in the "Public, Environmental & Occupational Health" category up to March 2022 and selected the 100 most cited articles. We recorded the number of citations, the journal, the year of publication, quartile, impact factor, institution, country, authors, topic, type of publication and collaborations. (3) Results: 926,665 documents were analyzed. The top 100 had 401,620 citations. The journal with the most articles was the Journal of Clinical Epidemiology and the one with the highest number of citations was Medical Care. The year with the highest number of articles in the top 100 was 1998. The country with the highest percentage of publications was the USA and the most productive institution was Harvard. The most frequent keywords were bias, quality, and extension. The largest collaboration node was between the USA, Canada, Germany, Spain, Australia, France, and Sweden. (4) Conclusions: This bibliometric study on Public, Environmental & Occupational Health provides valuable information not only to identify topics of interest in the analyzed category, but also to identify the differences in the topics they study.

[Display omitted] Extracellular vesicles (EV) are emergent therapeutic effectors that have reached clinical trial investigation. To translate EV-based therapeutic to clinic, the challenge is to demonstrate quality, safety, and efficacy, as required for any medicinal product. EV research translation into medicinal products is an exciting and challenging perspective. Recent papers, provide important guidance on regulatory aspects of pharmaceutical development, defining EVs for therapeutic applications and critical considerations for the development of potency tests. In addition, the ISEV Task Force on Regulatory Affairs and Clinical Use of EV-based Therapeutics as well as the Exosomes Committee from the ISCT are expected to contribute in an active way to the development of EV-based medicinal products by providing update on the scientific progress in EVs field, information to patients and expert resource network for regulatory bodies. The contribution of our work group "Extracellular Vesicle translatiOn to clinicaL perspectiVEs – EVOLVE France", created in 2020, can be positioned in complement to all these important initiatives. Based on complementary scientific, technical, and medical expertise, we provide EV-specific recommendations for manufacturing, quality control, analytics, non-clinical development, and clinical trials, according to current European legislation. We especially focus on early phase clinical trials concerning immediate needs in the field. The main contents of the investigational medicinal product dossier, marketing authorization applications, and critical guideline information are outlined for the transition from research to clinical development and ultimate market authorization.

The article provides information on the seminar conducted by the 2023 RIODD Congress (International Network on Organizations and Sustainable Development), scheduled for October 17-10, 2023, in Lille, France, on the topic of "Sustainability of Human Societies and their Ecosystems".

France’s reaction to Russia’s invasion of Ukraine was initially conciliatory. However, the current French President’ statements, Macron, gradually changed, suggesting a potential shift in France's stance. The French president recently suggested troops could be sent to Ukraine to fight the Russians, a move that could significantly impact the course of the war. Our paper aims to address this possibility. How feasible would this be from a military perspective? Second, are there any other relevant political actors that will support it? Third, why has Paris changed its position to such a radical stance? We start from the theoretical design of realist constructivism. Postcolonial theories and the concept of locked-in path dependence supported this research. The methods follow the path of historical synthesis, discourse analysis of key political actors, and text analysis of defense white papers. Quantitative military variables are used to understand France’s and the EU’s military-industrial complex capabilities and assess its potential. The collapse of France’s neocolonial empire in Africa and Russia’s growing influence in the region partially explains Macron’s discourse change. This is correlated with the need to follow a more independent European security policy and the worsening military situation in Ukraine. [ABSTRACT FROM AUTHOR]

This paper considers the relationship between exile and migration as reflected in a case study of biblical exegesis in modern Jewish thought. I consider the place of the biblical figure of Joseph in an early text by Léon Askenazi (also known as Manitou), a North African kabbalist and French intellectual, and a key spiritual leader of Francophone Jewry in the second half of the twentieth century. The paper begins by locating Askenazi within the mass migration, or "repatriation", of the Algerian Jewish community to metropolitan France. I then examine and analyze the reinterpretation of Joseph in an early and unpublished text by Askenazi. I show how Askenazi's explication departs from a common reading of the Joseph story by recasting it as a positive diasporic narrative with direct contemporary implications. I argue that during Askenazi's early years in Paris, he sought to offer a "Josephic" model for Jewish life in postwar France, a model which also functioned as an alternative to the Zionist ethos of the negation of exile. The paper's conclusion reflects on how Askenazi's ideas may speak to conversations on religion and immigration. [ABSTRACT FROM AUTHOR]

Technosols represent the group of soils whose properties and functions were defined by human action, formed from technogenic diagnostic materials. In this study, we use bibliometric techniques to investigate how environmental contamination has been addressed in global Technosol research and identify research trends that contribute to adequate Technosol management. We use 567 papers on Technosols from around the world available in the Web of Science database (2006–2021). Our results indicated that 34.2% of the global research on Technosols was related to environmental contamination, with significant growth over the years (R2 = 0.88). France was responsible for 29.8% of global research in contaminated Technosols. The main contaminant agents in Technosols were the heavy metals and the polycyclic aromatic hydrocarbons (PAHs), with a higher highlight for the first. Among the polluting metals, a greater concern was directed to the Pb, followed, in descending order, by the Zn, Cu, Cd, Ni, Cr, and As. The mining tailings were the main sources of the contaminant material. The combined effects of different pollutants, such as toxic metals and PAHs, in the biological community of Technosols and the combined use of environmental restoration strategies (phytoremediation and uses of organic compound, biochar, and biofertilizers) can be considered the main research trends in contaminated Technosols. Our results can be useful for research institutions and researchers around the world that seek development of strategies for the use and management of Technosols at the global level.

In this paper, we examine market-shaping literature that investigates how markets evolve over time. We focus on how controversial innovations gain acceptance as the result of the intentional strategies put into place by companies. We've carried a qualitative research based on secondary data collected from several online sources. Our study describes how a new packaging, can, had been introduced to the highly conservative market of wine in France. Our findings shed light on the opportunity for practitioners to implement controversial innovation in conservative markets and introduce a set of strategies to achieve such purpose.

Background: Changing the food environment is an important public health lever for encouraging sustainable food choices. Targeting the availability of vegetarian main meals served in cafeterias substantially affects food choice, but acceptability has never been assessed. We examined the effects of an availability intervention at a French university cafeteria on students' main meal choices, meal offer satisfaction and liking. Methods: A four-week controlled trial was conducted in a university cafeteria in Dijon, France. During the two-week control period, vegetarian main meals constituted 24% of the offer. In the subsequent two-week intervention period, this proportion increased to 48%, while all the other menu items remained unchanged. Students were not informed of the change. Student choices were tracked using production data, and daily paper ballots were used to assess student satisfaction with the meal offer and liking of the main meal they chose (score range [1;5]). Nutritional quality, environmental impact, and cost of production of meal choices were calculated for each lunchtime. Food waste was measured over 4 lunchtimes during control and intervention periods. An online questionnaire collected student feedback at the end of the study. Results: Doubling availability of vegetarian main meals significantly increased the likelihood of choosing vegetarian options (OR = 2.57, 95% CI = [2.41; 2.74]). Responses of the paper ballots (n = 18,342) indicated slight improvements in meal offer satisfaction from 4.05 ± 0.92 to 4.07 ± 0.93 (p = 0.028) and in liking from 4.09 ± 0.90 to 4.13 ± 0.92 (p < 0.001) during control and intervention periods, respectively. The end-of-study questionnaire (n = 510) revealed that only 6% of students noticed a change the availability of vegetarian main meals. The intervention led to a decrease in the environmental impact of the main meals chosen, a slight decrease in nutritional quality, a slight increase in meal costs and no change in food waste. Conclusions: Doubling availability of vegetarian main meals in a university cafeteria resulted in a twofold increase in their selection, with students reporting being more satisfied and liking the main meals more during the intervention period. These results suggest that serving an equal proportion of vegetarian and nonvegetarian main meals could be considered in French university cafeterias to tackle environmental issues. Trial registration: Study protocol and analysis plan were pre-registered on the Open Science Framework (https://osf.io/pf3x7/). [ABSTRACT FROM AUTHOR]

In the atmosphere, aerosols can originate from numerous sources, leading to the mixing of different particle types. This paper introduces an approach to the partitioning of aerosol mixtures in terms of backscattering coefficients. The method utilizes data collected from the Mie–Raman–fluorescence lidar, with the primary input information being the aerosol backscattering coefficient (β), particle depolarization ratio (δ), and fluorescence capacity (GF). The fluorescence capacity is defined as the ratio of the fluorescence backscattering coefficient to the particle backscattering coefficient at the laser wavelength. By solving a system of equations that model these three properties (β , δ and GF), it is possible to characterize a three-component aerosol mixture. Specifically, the paper assesses the contributions of smoke, urban, and dust aerosols to the overall backscattering coefficient at 532 nm. It is important to note that aerosol properties (δ and GF) may exhibit variations even within a specified aerosol type. To estimate the associated uncertainty, we employ the Monte Carlo technique, which assumes that GF and δ are random values uniformly distributed within predefined intervals. In each Monte Carlo run, a solution is obtained. Rather than relying on a singular solution, an average is computed across the whole set of solutions, and their dispersion serves as a metric for method uncertainty. This methodology was tested using observations conducted at the ATOLL (ATmospheric Observation at liLLe) observatory, Laboratoire d'Optique Atmosphérique, University of Lille, France.

Amidst the global energy crisis in 2022, the Spanish and Portuguese governments introduced a subsidy to natural gas ("the Iberian exception"), attempting to lower the wholesale electricity market prices, with the understanding that gas-fired-combined cycle gas turbines (CCGTs) are price-setting technologies most of the time, directly or indirectly. The subsidy succeeded in lowering the market price but induced several other effects, such as (1) the increase in cleared energy in the Spanish market (mostly produced with gas), (2) the bias in the import/export cross-border position between Spain and France (Spain became a net exporter to France immediately), or (3) the consequent increase in congestion rents, which serve to lightly finance the subsidy, among other effects. This paper provides a framework for clustering the different effects based on the market participation phases: the subsidy, the market bidding, the market results, and surplus and rents. Moreover, this paper builds on the theoretical market models, with and without subsidies, and with and without cross-border exchanges. Based on the real market bids, the subsidies, and the generators' data, we reconstruct the supply and demand curves and simulate the counterfactual market scenarios in order to illustrate and quantify the effects. We highlight the quantification of the theoretical effect of the transfer of rents, from non-fossil to fossil fuel producers, induced by the gas subsidy. [ABSTRACT FROM AUTHOR]

In 2019, Zolgensma, a gene therapy for patients suffering from Spinal Muscular Atrophy (SMA), became famous for being 'the most expensive drug ever'. Its high price was justified by 'the value' that the drug will bring to patients and society, illustrating a rationale that has come to be known as value-based pricing. This paper builds on the literature in valuation studies and economic sociology, and on the debates that the case of Zolgensma triggered in France, to provide a conceptual and empirical analysis of a value-based formulation of prices. We argue that formulating prices out of value produces an orientation towards the future which has epistemic and political consequences. We analyse Zolgensma's value-based price as a composite of narratives and calculations that operates as a regulatory tool, a contractual arrangement, and an object of expertise. In these different settings, its distinctive temporality questions the commensurability of estimated benefits and desirable futures, the treatment of uncertainty, and the relevance of past costs and future value.

Over the last decades, scholars have increasingly called for the 'deterritorialization' of the notion of citizenship. The realities concerning citizenship have changed with new expressions of transnationalism. However, whereas the main body of research has focused on the transnational aspects of citizenship among migrants in the form of their transnational political practices and dual nationalities, their descendants have received far less attention. This paper examines the political practices of Kurdish migrants' descendants in France and Germany and their narratives of identity and citizenship. We employ migrant descendants' political activism as an empirical entry point to gain insight into the meanings they attach to citizenship. The paper draws from two qualitative datasets collected in France (2015–2017) and Germany (2015–2023) with individuals of Kurdish background, who were born to migrant families arriving from Turkey in the 1980s and 1990s. The findings show that national contexts – both in grandparents'/parents' country of departure and the country of arrival – and the transnational, diasporic and even supranational space (EU) shape migrant descendants' political activism, identity construction and consequently resonate in the meanings they attach to citizenship. This study highlights the need to approach migrants' descendants as transnational citizens in their own right. [ABSTRACT FROM AUTHOR]

The paper brings to the attention of researchers the morphological changes of metal oxides, which appear as a result of the process of physical solar vapor deposition (SPVD) based on experiments carried out at the CNRS-PROMES laboratory, UPR 8521, belonging to the French National Centre for Scientific Research (CNRS). The SPVD process is an innovative tool who has been developed in 2 kW solar furnaces at Odeillo-Font Romeu, France, to synthesis pure and doped nanoparticles, such as: ZnO, CeO2, ZrO2, BiO2, SiO. A variety of metal oxides nanoparticles have been obtained by focusing solar energy on pellets of commercial powders through the controlled process of vaporization followed by condensation directed on a cooper tube or on nanoporous filter. After the micrograph analysis the change of shape and dimension can be observed depending on the type of oxide and the process parameters. It is noticed the appearance of new morphologies, not found in other synthesis methods. The paper brings new information about morphological and dimensional changes after synthesis by physical process which can be essential for researchers, in the choice of methods for the elaboration of nanomaterials.

Purpose: The literature mostly investigates the business cycle transmission of the United Kingdom (UK) and France as a part of a wider group (e.g. European Exchange Rate Mechanism or G7), despite their historical links and regional significance. Thus, herein paper aims to analyse the inter-dependence of these economies and how a shock from one of them affects the other for the data since 1978 to 2019. Design/methodology/approach: In this paper, first, preliminary statistics were calculated in order to describe the historical relationship between these countries. The econometric part estimates the vector auto-regression model (VAR) to assess the inter-dependence of the economies. VAR model allows further to inspect the impulse response functions that shows the shock dynamics from one country to another. In order to verify if a shock from one of the economies is important to another, the study uses granger causality test. Findings: The study establishes a strong link between these countries. A business cycle is transmitted significantly between the economies of France and UK, with a single standard deviation shock from France resulting in a long term effect of 0.4% change in gross domestic product (GDP) of UK and 1% vice versa. Additionally changes in GDP of both of the countries significantly Granger-cause change to GDP of the corresponding economy. Originality/value: This is the first empirical study investigating the business cycle transmission between France and UK and providing a quantitative assessment of their inter-dependence.

Addressing sustainability challenges requires fundamental transformations in electricity, heat, mobility, and agri-food systems. To do so, research and policy efforts tend to emphasise the importance of fostering new, more sustainable systems through innovation. Instead, this paper focuses explicitly on the "flipside" of innovation: The fate of established systems faced with their potential destabilisation and decline. It is argued that any transition in consumption-production systems involves a combination of innovation (something new emerges) and destabilisation (something old is being challenged). To examine the role of destabilisation, decline, and phase-out for policy and practice efforts, this paper advances conceptual and empirical contributions. Conceptually, it elaborates a framework based on three interacting destabilisation mechanisms: The build-up of pressures, strategic responses by central system actors, and changing commitments to reproductive activities. Empirically, it draws on the historic dismantling of electric tramways in France. The decline of the tramway in France followed a gradual erosion pattern resulting from the long-term degradation of technical, political, and economic conditions, which was accelerated by a relatively rapid phase-out programme. A discussion section offers insights on the temporality of destabilisation, the context of phase-out decisions, and the interaction of destabilisation and innovation processes.

Medical students are potential marketing targets for pharmaceutical companies because established prescribing habits are not easily altered. In 2014, Bruno Etain and several other researchers published a paper which investigated the knowledge of and opinions on potential conflict of interest (COI) with regard to preclinical and clinical students enrolled in medical schools in France and residents working in hospitals. An empirical survey study with Korean medical students concerning their educational experiences and views on conflicts of interest and comparing and contrasting the results with Etain's study of French medical students. Receipt of direct or indirect financial offerings from pharmaceutical industries was not properly recognised as COI by the medical students. Therefore, strengthening education on COI and implementing institutional improvements for COI disclosure are essential to prevent bias caused by COI and enhance awareness levels regarding COI.
