Populism combines the following characteristics:a rejection of economic policies linked to globalization;a condemnation of political and economic elites perceived as allied,directly or indirectly,to globalization policies;a nationalist conception of the national interest;a mistrust of immigration,seen as a threat to identity;as for populism’s supporters,a rather popular sociological profile,and an electoral profile that tends toward the“hard right”(“droite dure”),without ruling out bridges to the“hard left”(“gauche dure”).Having said this,I propose to defend three theses:populism is not the solution to the problems of the countries where it is developing,whether in France,the United States or elsewhere;it would be dangerous,however,to ignore the crises of which populism is the product;it is essential to take the measure of the problems that favor its emergence and to try to provide answers to them.

考虑到非晶合金具有独特的无序微观结构,其表现出极为复杂的弛豫动力学特性.动态弛豫行为在非晶合金中普遍存在,深刻理解其机制对于解构非晶合金固有的非均匀微观结构至关重要.少量元素的添加是调控非晶合金微观结构有效手段之一.本研究以玻璃形成能力良好的Cu_(46)Zr_(47-x)Hf_(x)Al_(7)(x=0,8)非晶合金为模型合金,运用动态力学分析方法研究复模量随频率和温度的变化,进而探究Hf元素取代Zr元素对动态弛豫的影响.在动态力学频率谱中,借助准点缺陷理论阐明非晶合金在玻璃转变温度T_(g)以下处于等构型状态,准点缺陷浓度保持恒定;而在T_(g)以上,准点缺陷浓度随温度的上升呈线性增加.Hf元素的添加会降低玻璃体系等构型状态下的准点缺陷浓度,并抑制原子迁移能力.通过获取连续和离散的弛豫时间分布,直观展示了非晶合金的动力学非均匀性特征.在动态力学温度谱中,Hf元素的引入增加了玻璃体系的混合焓,抑制了β弛豫强度.进一步从内耗角度表明,Hf元素的引入不仅提高了与β弛豫相关的基本结构单元的激活难度,还增加了整个β弛豫过程的激活能.

Acute infections cause local and systemic disorders which can lead in the most severe forms to multi-organ failure and eventually to death. The host response to infection encompasses a large spectrum of reactions with a concomitant activation of the so-called inflammatory response aimed at fighting the infectious agent and removing damaged tissues or cells, and the anti-inflammatory response aimed at controlling inflammation and initiating the healing process. Fine-tuning at the local and systemic levels is key to preventing local and remote injury due to immune system activation. Thus, during bacterial sepsis and Coronavirus disease 2019 (COVID-19), concomitant systemic and compartmentalized pro-inflammatory and compensatory anti-inflammatory responses are occurring. Immune cells (e.g., macrophages, neutrophils, natural killer cells, and T-lymphocytes), as well as endothelial cells, differ from one compartment to another and contribute to specific organ responses to sterile and microbial insult. Furthermore, tissue-specific microbiota influences the local and systemic response. A better understanding of the tissue-specific immune status, the organ immunity crosstalk, and the role of specific mediators during sepsis and COVID-19 can foster the development of more accurate biomarkers for better diagnosis and prognosis and help to define appropriate host-targeted treatments and vaccines in the context of precision medicine.

Môle Saint-Nicolas, like all other communes in the Republic of Haiti, faces increasing climate variability, impacting agricultural production and water resources. Consequently, there is a pressing need for adaptation to these climatic changes. This research aims to showcase the adaptation strategies deployed by farmers to cope with the increasing climate variability. Surveys were conducted through group and individual discussions with a randomly selected cohort of 150 farmers. Two types of analysis were performed: quantitative and qualitative. The quantitative data analysis was conducted using Statistical Package for the Social Sciences (SPSS) software. The findings reveal that farmers have perceived changes in rainfall patterns, temperature, wind, and their environment. These changes manifest as irregular rainfall, higher temperatures, prolonged drought periods, violent winds accompanied by rain, premature cessation of rains, and reduced flow from water sources. In response, the most common adaptation strategies adopted include selecting new cultivars, early-maturing varieties, crop rotation and diversification, canal dredging, new soil preparation methods, upstream water source protection, and micro-watershed management. The significance of this research lies in its contribution to enhancing farmers’ adaptive capacities by alerting stakeholders in the irrigated perimeters about the consequences of climate change, thereby incorporating the real needs of farmers in future projects.

This review summarizes the recent advances on the application of ^(57)Fe Mössbauer spectrometry to study the magnetic and phase characteristics of Nd–Fe–B-based permanent magnets. First of all, the hyperfine structures of the Ce_(2)Fe_(14)B,(Ce,Nd)_(2)Fe_(14)B and MM_(2)Fe_(14)B phases are well-defined by using the model based on the Wigner-Seitz analysis of the crystal structure. The results show that the isomer shift δ and the quadrupole splitting öEQ of those 2:14:1 phases show minor changes with the Nd content, while the hyperfine field Bhfincreases monotonically with increasing Nd content and its value is influenced by the element segregation and phase separation in the 2:14:1 phase. Then, the hyperfine structures of the low fraction secondary phases are determined by the ^(57)Fe Mössbauer spectrometry due to its high sensitivity. On this basis,the content, magnetic behavior, and magnetization of the REFe_(2) phase, the amorphous grain boundary(GB) phase, and the amorphous worm-like phase, as well as their effects on the magnetic properties, are systematically studied.
