Authors: Glatt Ryan M. , Amos Amylee , Merrill David A. , Hodes John F. , Wong Claudia L. , Miller Karen J. , Siddarth Prabha
Published: March 2024

Introduction: Adopting healthy lifestyle behaviors has the potential to slow cognitive decline in older adults by reducing risks associated with dementia. Curriculum-based group health coaching may aid in establishing behavior change centered for dementia risk factors. Methods: In this pilot clinical care patient group study (n = 6), we examined the effects of a six-month online Cognitive Health Program combined with a weekly telehealth support group led by the course creator, and personalized health optimization by a collaborating physician, in older adults with subjective cognitive decline. Cognition was assessed at baseline and post-intervention using a computerized battery. Results: Cognitive changes were estimated with nonparametric tests and effect sizes (Cohen’s d). Results showed significant improvements in global cognition (p < 0.03, d = 1.6), spatial planning (p < 0.01, d = 2.3), and visuospatial processing (p < 0.05, d = 1.1) compared to baseline. Participants reported high levels of satisfaction with the virtual group format and online curriculum. Conclusions: This small pilot study suggests that a virtual six-month personalized health coaching group with self-paced online health education is feasible and potentially efficacious for improving cognition in participants with subjective cognitive complaints. This format may facilitate behavior change to slow cognitive decline. Future studies should include a control group, a larger, more diverse sample as well as assessing mood and other subjective measures.
Why Do New Parents Stop Practising Sport? A Retrospective Study towards the Determinants of Dropping Out after Becoming a Parent
Authors: Bekhuis Hidde , van Houten Jasper , van Abswoude Femke
Published: March 2024

Despite the known health benefits of sport, recent studies showed that parenthood is related to decreased sport participation. Changes in sport behaviour after becoming a parent have been explained by gender or with the rational resource perspective of limited time and energy. However, the latter is mostly theoretical, since empirical insights on resource mechanisms are scarce. We want to improve and go beyond these explanations by investigating them empirically and by examining sport socialisation during the formative years as an alternative explanation. Consequently, our main objective is to explain changes in sport participation after becoming a parent with gender, limited resources and socialisation with sport. To this end, we employ representative Dutch survey data of new parents (n = 594), containing detailed information on sport careers and sport socialisation, as well as babysitter availability, partner support and physical discomfort after childbirth. The results of the logistic regression analyses show that, besides gender and resource mechanisms, sport socialisation and social support seem to have a great impact on sport behaviour when people become parents. That is, men are more likely to continue sport participation, as well as people with more resources (physical, temporal and social) and more socialisation with sport during the formative years. So including sport socialisation and social support seems necessary to better explain and prevent sport dropout during major life transitions, like becoming a parent.
Modelling Value-Oriented Legal Reasoning in LogiKEy
Authors: Benzmüller Christoph , Fuenmayor David , Lomfeld Bertram
Published: March 2024

The logico-pluralist LogiKEy knowledge engineering methodology and framework is applied to the modelling of a theory of legal balancing, in which legal knowledge (cases and laws) is encoded by utilising context-dependent value preferences. The theory obtained is then used to formalise, automatically evaluate, and reconstruct illustrative property law cases (involving the appropriation of wild animals) within the Isabelle/HOL proof assistant system, illustrating how LogiKEy can harness interactive and automated theorem-proving technology to provide a testbed for the development and formal verification of legal domain-specific languages and theories. Modelling value-oriented legal reasoning in that framework, we establish novel bridges between the latest research in knowledge representation and reasoning in non-classical logics, automated theorem proving, and applications in legal reasoning.
A Review of Waterjet Cutting Research towards microAWJ and the Definition of the Waterjet Digital Twin
Authors: Annoni Massimiliano
Published: March 2024

This review paper aimed to draw the red line passing through almost 25 years of research on waterjet cutting carried out at WJ_Lab, the waterjet laboratory of the Department of Mechanical Engineering of Politecnico di Milano. The purpose was not to just historically analyse the obtained scientific results by themselves but to make them even more useful by introducing the concept of the waterjet digital twin passing through the accuracy improvements due to microAWJ. This strategy effectively creates synergy among the topics and gives the opportunity to researchers in this field to both have an example of how research in industrial manufacturing processes can be guided by scientific and industrial needs, at least from the author’s point of view, and to appreciate how it can be made useful for further improvements by introducing a powerful concept as the digital twin.

Published: March 2024

To study the effect of aluminum and nickel elements on the microstructures and properties of the nickel–aluminum bronze (NAB) alloy, four kinds of alloys with different compositions, ZCuAl7–7–4–2, ZCuAl8-6-4-2, ZCuAl9-5-4-2, and ZCuAl10-4-4-2, are prepared by vacuum-melting technology. The effects of different Al/Ni ratios on the microstructures of NAB are investigated using a metalloscope, scanning electron microscopy, transmission electron microscopy, and XPS analysis. The mechanical property is evaluated with microhardness testing and tensile mechanical testing. The corrosion resistance is evaluated using mass-loss testing, electrochemical testing, and corrosion-product characterization. The results show that with the increase of the Al/Ni ratio, the content of precipitated phases increases, while β′ and hard κ, which have a different morphology, appear. As the Al/Ni ratio rises from 1 to 2.5, the hardness increases from 104 HV to 202 HV, and the tensile strength increases by 394 MPa from 356 MPa to 751 MPa, but the elongation decreases substantially from 50.50% to 11.00%. The best corrosion resistance is shown on ZCuAl7-7-4-2, with a corrosion rate of 0.00267 mm/a after 30 d of static immersion corrosion in 3.5 wt.% NaCl solution. Through electrochemical testing and corrosion-product characterization, it is found that ZCuAl7-7-4-2 has the largest polarization resistance Rp, and the selective corrosion of the surface is mild.

Published: March 2024

Among solution-processable metal oxides, zinc oxide (ZnO) nanoparticle inks are widely used in inverted organic solar cells for the preparation, at relatively low temperatures (<120 °C), of highly efficient electron-transporting layers. There is, however, a recent interest to develop more sustainable and less impacting methods/strategies for the preparation of ZnO NPs with controlled properties and improved performance. To this end, we report here the synthesis and characterization of ZnO NPs obtained using alternative reaction solvents derived from renewable or recycled sources. In detail, we use (i) recycled methanol (r-MeOH) to close the loop and minimize wastes or (ii) bioethanol (b-EtOH) to prove the effectiveness of a bio-based solvent. The effect of r-MeOH and b-EtOH on the optical, morphological, and electronic properties of the resulting ZnO NPs, both in solution and thin-films, is investigated, discussed, and compared to an analogous reference material. Moreover, to validate the properties of the resulting materials, we have prepared PTB7:PC71BM-based solar cells containing the different ZnO NPs as a cathode interlayer. Power conversion efficiencies comparable to the reference system (≈7%) were obtained, validating the proposed alternative and more sustainable approach.
Heat Treatments for Minimization of Residual Stresses and Maximization of Tensile Strengths of Scalmalloy® Processed via Directed Energy Deposition
Authors: Boillat-Newport Rachel , Isanaka Sriram Praneeth , Kelley Jonathan , Liou Frank
Published: March 2024

Scalmalloy® is an Al-Mg-Sc-Zr-based alloy specifically developed for additive manufacturing (AM). This alloy is designed for use with a direct aging treatment, as recommended by the manufacturer, rather than with a multistep treatment, as often seen in conventional manufacturing. Most work with Scalmalloy® is conducted using powder bed rather than powder-fed processes. This investigation seeks to fill this knowledge gap and expand beyond single-step aging to promote an overall balanced AM-fabricated component. For this study, directed energy deposition (DED)-fabricated Scalmalloy® components were subjected to low-temperature treatments to minimize residual stresses inherent in the material due to the layer-by-layer build process. X-ray diffraction (XRD) indicated the possibility of stress minimization while reducing the detriment to mechanical strength through lower temperature treatments. Microstructural analyses consisting of energy dispersion spectroscopy (EDS) and electron backscatter diffraction (EBSD) revealed the presence of grain growth detrimentally affecting the strength and elongation made possible by very small grains inherent to AM and rapid solidification. Tensile testing determined that treatment at 175 °C for 1 h provides the best relief from the existing residual stresses; however, this is accompanied by a diminishment in the yield and tensile strength of 19 and 9.5%, respectively. It is noted that treatment at 175 °C for 2 h did not provide as great of a decrease in residual stresses, theorized to be the result of grain growth and other strengthening mechanisms further stressing the structure; however, the residual stresses are still significantly diminished compared with the as-built condition. Furthermore, a minimal reduction of the tensile strengths indicates the possibility of finding a balance between property diminishment and stress state through the work proposed here.
The Development of the Stress-Free Polishing System Based on the Positioning Error Analysis for the Deterministic Polishing of Jet Electrochemical Machining
Authors: Wang Ke , Wang Hongding , Zhang Yanlong , Shi Huirong , Shi Jiahao
Published: March 2024

Deterministic polishing based on jet electrochemical machining (Jet-ECM) is a stress-free machining method for low-rigidity and ultra-precision workpieces. The nozzle is equivalent to a special tool in deterministic polishing, and the workpiece material is removed using the mechanism of electrochemical dissolution at the position where the nozzle passes. By precisely regulating the nozzle’s movement speed and dwell time, the quantity of material removed from the workpiece at a designated position can be finely adjusted. With this mechanism, the improvement of the workpiece shape accuracy can be achieved by planning the nozzle trajectory and nozzle movement speed. However, due to the positioning errors of the polishing device, the actual position of the nozzle may deviate from the theoretical position, resulting in errors in material removal amount, which affects the accuracy and stability of the polishing process. This study established a mathematical model to analyze the influence of nozzle positioning errors in deterministic polishing based on Jet-ECM. This model has been used to design a specific deterministic polishing device based on Jet-ECM. With the proposed deterministic polishing device, the surface shape of the workpiece is converged. The surface peak-to-valley (PV) value of the φ 50 mm workpiece (valid dimensions = 90% of the central region) indicated that the shape error of the surface was reduced from 2.67 μm to 1.24 μm in 34 min. The power spectral density (PSD) method was used to evaluate the height distribution and height characteristics of the workpiece surface. The results show that the low frequency spatial error is reduced significantly after processing. This study improves the accuracy of the stress-free deterministic polishing methods and further expands the use of deterministic polishing in industry.

Published: March 2024

Although meat and meat products are important sources of protein in the human diet, consumption appears to be a predisposing factor in the onset of several civilisation diseases, particularly red meat and its products. One way to reduce diet-related diseases is to guide consumers towards consciously purchasing healthier foods by including a nutrition declaration on product labels, such as by using a “front-of-pack” (FOP) labelling system. This study aimed to determine the Nutri-Score classes for processed meat products, distinguish products that are potentially better for consumers, and determine whether the refined algorithm significantly contributed to a change in product classification. An analysis of the labels of 1700 products available on the Polish market indicated that most processed meat products qualified as class D and E. Comparing the refined Nutri-Score calculation algorithm with the original algorithm resulted in a slight change in product allocation. Poultry products were ranked more favourably than red meat products. The most significant change in product allocation (by 35.2%) was achieved by reducing salt content by 30% and fat content by 10%. Among the processed meat products, some are more highly ranked and are hence considered better from a nutritional perspective than others in that group.

Published: March 2024

(1) Background: Appetitive traits in adults can be measured through the Adult Eating Behavior Questionnaire (AEBQ), a questionnaire adapted from the Child Eating Behavior Questionnaire (CEBQ). The AEBQ has been validated in several countries. The aim of the present study was to explore and validate the factor structure of the Italian version of the AEBQ. Furthermore, convergent validity and correlations between factors and BMI were explored to assess its criterion validity. (2) Methods: Participants (N = 624, mean age of 32.08 ± 14.94 years) completed the AEBQ, the Eating Attitude Test (EAT-40), and the Dutch Eating Behavior Questionnaire (DEBQ). They also self-reported demographic and anthropometric data. A Confirmatory Factor Analysis (CFA) was used to test three different alternative models that emerged in previous validations. (3) Results: The CFA revealed a good model fit (RMSEA = 0.0634, TLI = 0.894, CFI = 0.907) for the 7-factor structure, without the Hunger items, showing a valid and reliable (Cronbach’s α > 0.7) structure. Convergent and divergent validity of the AEBQ yielded favorable results, and relationships between the AEBQ and BMI factors revealed that the Food Approach traits were positively associated with BMI. (4) Conclusions: Finally, this study provides initial support for the use of the AEBQ as a valid and reliable tool to measure a wide range of appetitive traits in the adult Italian population.
Bioinspired Thermal Conductive Cellulose Nanofibers/Boron Nitride Coating Enabled by Co-Exfoliation and Interfacial Engineering
Authors: Wan Xinyuan , Xia Xiaojian , Chen Yunxiang , Lin Deyuan , Zhou Yi , Xiong Rui
Published: March 2024

Thermal conductive coating materials with combination of mechanical robustness, good adhesion and electrical insulation are in high demand in the electronics industry. However, very few progresses have been achieved in constructing a highly thermal conductive composites coating that can conformably coat on desired subjects for efficient thermal dissipation, due to their lack of materials design and structure control. Herein, we report a bioinspired thermal conductive coating material from cellulose nanofibers (CNFs), boron nitride (BN), and polydopamine (PDA) by mimicking the layered structure of nacre. Owing to the strong interfacial strength, mechanical robustness, and high thermal conductivity of CNFs, they do not only enhance the exfoliation and dispersion of BN nanoplates, but also bridge BN nanoplates to achieve superior thermal and mechanical performance. The resulting composites coating exhibits a high thermal conductivity of 13.8 W/(m·K) that surpasses most of the reported thermal conductive composites coating owing to the formation of an efficient thermal conductive pathway in the layered structure. Additionally, the coating material has good interface adhesion to conformably wrap around various substrates by scalable spray coating, combined with good mechanical robustness, sustainability, electrical insulation, low-cost, and easy processability, which makes our materials attractive for electronic packaging applications.
A Review of Antimicrobial Polymer Coatings on Steel for the Food Processing Industry
Authors: Sukhareva Ksenia , Chernetsov Vasily , Burmistrov Igor
Published: March 2024

This article will focus on the issue of protection against the pathogenic biofilm development on steel surfaces within the food sectors, highlighting steel’s prominence as a material choice in these areas. Pathogenic microorganism-based biofilms present significant health hazards in the food industry. Current scientific research offers a variety of solutions to the problem of protecting metal surfaces in contact with food from the growth of pathogenic microorganisms. One promising strategy to prevent bacterial growth involves applying a polymeric layer to metal surfaces, which can function as either an antiadhesive barrier or a bactericidal agent. Thus, the review aims to thoroughly examine the application of antibacterial polymer coatings on steel, a key material in contact with food, summarizing research advancements in this field. The investigation into polymer antibacterial coatings is organized into three primary categories: antimicrobial agent-releasing coatings, contact-based antimicrobial coatings, and antifouling coatings. Antibacterial properties of the studied types of coatings are determined not only by their composition, but also by the methods for applying them to metal and coating surfaces. A review of the current literature indicates that coatings based on polymers substantially enhance the antibacterial properties of metallic surfaces. Furthermore, these coatings contribute additional benefits including improved corrosion resistance, enhanced aesthetic appeal, and the provision of unique design elements.
Exploiting the Matched Filter to Improve the Detection of Methane Plumes with Sentinel-2 Data
Authors: Wang Hongzhou , Fan Xiangtao , Jian Hongdeng , Yan Fuli
Published: March 2024

Existing research indicates that detecting near-surface methane point sources using Sentinel-2 satellite imagery can offer crucial data support for mitigating climate change. However, current retrieval methods necessitate the identification of reference images unaffected by methane, which presents certain limitations. This study introduces the use of a matched filter, developing a novel methane detection algorithm for Sentinel-2 imagery. Compared to existing algorithms, this algorithm does not require selecting methane-free images from historical imagery in methane-sensitive bands, but estimates the background spectral information across the entire scene to extract methane gas signals. We tested the algorithm using simulated Sentinel-2 datasets. The results indicated that the newly proposed algorithm effectively reduced artifacts and noise. It was then validated in a known methane emission point source event and a controlled release experiment for its ability to quantify point source emission rates. The average estimated difference between the new algorithm and other algorithms was about 34%. Compared to the actual measured values in the controlled release experiment, the average estimated values ranged from −48% to 42% of the measurements. These estimates had a detection limit ranging from approximately 1.4 to 1.7 t/h and an average error percentage of 19%, with no instances of false positives reported. Finally, in a real case scenario, we demonstrated the algorithm’s ability to precisely locate the source position and identify, as well as quantify, methane point source emissions.
Symmetric Double-Supplemented Nested Array for Passive Localization of Mixed Near-Field and Far-Field Sources
Authors: Wu Yichen , Qi Junwei , Wang Ying-Zhen , Li Yingsong
Published: March 2024

In mixed-field source localization, the physical properties of a sensor array, such as the degrees of freedom (DOFs), aperture, and coupling leakage, directly affect the accuracy of estimating the direction of arrival (DOA). Compared to conventional symmetric uniform linear arrays, symmetric non-uniform linear arrays (SNLAs) have a greater advantage in mixed-field source localization due to their larger aperture and higher DOF. However, current SNLAs require improvements in their physical properties through modifications to the array structure in order to achieve more accurate source localization estimates. Therefore, this study proposes a symmetric double-supplemented nested array (SDSNA), which translates nested subarrays based on symmetric nested arrays to increase the aperture and inserts two symmetric supplemented subarrays to fill the holes created by the translation. This method results in longer consecutive difference coarray lags and larger apertures. The SDSNA is compared to existing advanced SNLAs in terms of their physical properties and DOA estimation. The results show that, with the same number of sensors, the SDSNA has a higher DOF, a larger aperture, and smaller coupling, indicating the advantages of the SDSNA in terms of its physical properties. Under the same experimental conditions, the SDSNA has a lower root-mean-square error of source location, thus indicating better performance in terms of both DOA and distance estimation.
The Entrepreneurial Leadership, Innovative Behaviour, and Competitive Advantage Relationship in Manufacturing Companies: A Key to Manufactural Development and Sustainable Business
Authors: Ercantan Kansu , Eyupoglu Şerife Z. , Ercantan Özlem
Published: March 2024

The ability of management to influence employee attitudes and behaviours towards organizational goals is pivotal for an organization’s competitiveness, development, and survival. The study’s objective was to investigate the link between entrepreneurial leadership, competitive advantage, and manufacturing development, mediated by employees’ innovative behaviour, via the lens of resource-based view theory. Convenience sampling was used to collect quantitative data from the 378 manufacturing sector employees through the use of a cross-sectional design. There is a lack of research on the underlying mechanisms by which leaders influence organizational processes, such as innovation stimulation. This study explores the psychological mechanisms influencing entrepreneurial leadership and employee innovative behaviour, revealing that entrepreneurial leadership reduces work uncertainty, encourages innovation, and significantly impacts a firm’s competitive advantage in the market. The findings of the study revealed that entrepreneurial leadership fosters an encouraging and supportive environment in the workplace, which in turn leads to a sustainable competitive advantage. Additionally, the findings showed that innovative behaviour significantly mediates the relationship between entrepreneurial leadership and competitive advantage. By expanding the applicability of resource-based view theory, the results of this research also contribute to the comprehension of the interplay between innovative attitudes, manufactural development, competitive advantage, and leadership, specifically in the context of manufacturing sector organizations.

Published: March 2024

Canoe modality in flatwater canoeing has a clear asymmetrical nature. This study aimed (1) to determine the magnitude and direction of neuromuscular properties, range of motion (ROM) and lower-limb strength asymmetries in female and male canoeists; (2) to establish sex-individualized asymmetry thresholds for canoeists’ neuromuscular properties, ROM and lower-limb strength; and (3) to determine the relationship of canoeists’ neuromuscular properties, ROM and lower-limb strength asymmetries with a specific canoe–dynamometer performance test. Twenty-one international canoeists were assessed through tensiomyography (TMG), ROM, lower-limb explosive strength, and a specific canoe incremental dynamometric test. The magnitude of asymmetry assessed through TMG and ROM was not modulated either by sex or performance level (international medal vs. non-medal). Females showed greater asymmetry than males on muscle tone of the erector spinae towards non-stroke side (22.75% vs. 9.72%) and the tibialis anterior (30.97% vs. 16.29%), and Fmax in explosive leg press (2.41% vs. 0.63%) towards the stroke side. International medalists showed greater asymmetry in semitendinosus contraction time towards non-stroke side (20.51% vs. 9.43%) and reached Vmax earlier in explosive leg press towards stroke side leg (19.20% vs. 9.40%). A greater asymmetry in Fmax and in Vm, and a smaller asymmetry in Tvmax and in leg press showed a small predictive capacity for canoeists’ performance on a specific canoe incremental dynamometry test. Reporting reference data from world-class canoeists’ asymmetries can be of great importance for coaches to periodically control lateral asymmetry.

Published: March 2024

The aero-engine serves as the “heart” of an aircraft and is a primary factor determining the aircraft’s performance. Among the crucial components in the core of aero-engines, aero-engine compressor blades stand out as extremely important. They are not only numerous but also characterized by a multitude of parameters, making them the most complex parts in an aero-engine. This paper aims to address the trade-off between accuracy and efficiency in the existing measurement methods for asymmetric blades. Non-contact measurements were conducted using a structured light system composed of a stereo camera and a DLC projector. The point cloud data of the blades are processed using methods such as the PCA (Principal Component Analysis) algorithm, binary search, and least squares fitting. This paper established a fringe-projection profilometry light sensor system for the multi-view measurement of the blades. High-precision rotary tables are utilized to rotate and extract complete spatial point cloud data of aviation blades. Finally, measurements and comparative experiments on the blade body are conducted. The obtained blade point cloud data undergo sorting and denoising processes, resulting in improved measurement accuracy. The measurement error of the blade chord length is 0.001%, the measurement error of blade maximum thickness is 0.895%, compared to CMM (Coordinate Measuring Machine), where the measurement error of chord is 0.06%.

L’Allemagne dans les autobiographies des germanistes français publiées depuis 1990.

Depuis la fin du « court vingtième siècle » (E. Hobsbawm) ont paru plusieurs livres à caractère autobiographique écrits par des germanistes français. Les auteurs, Pierre Bertaux, Pierre Grappin, Joseph Rovan et Alfred Grosser, sont nés entre 1907 et 1925. Quelle vision de l’Allemagne leurs livres déploient-ils ? Une vision fondée sur un point de vue français, sur un attachement « premier » aux paysages de France et surtout à la langue et à la culture françaises, telles que les transmettait l’école de la IIIe République. Ces auteurs ont tous souffert du nazisme. À l’exception peut-être de Pierre Bertaux, ils manifestent tout de même un attachement « second » à l’Allemagne, à ses poètes (Grappin), à ses musiciens (Grosser), à ses villes et ses paysages (Rovan, Grappin), à ses intellectuels, aux institutions et au personnel politique de la RFA (Rovan, Grosser). Seul Pierre Grappin a aussi entretenu, dans les années 70 et 80, des relations suivies avec des chercheurs de RDA. Pierre Bertaux n’a pas vécu la chute du Mur de Berlin, Pierre Grappin s’est réjoui de la perspective d’une Europe apaisée. Aujourd’hui, Joseph Rovan plaide pour une Europe fédérant des nations bien trop petites pour s’imposer face aux grandes puissances tandis qu’Alfred Grosser rappelle aux Français et aux Allemands qu’ils ne sont pas le centre du monde et qu’ils ont beaucoup à apprendre les uns des autres.
La Prusse orientale de Michel Tournier
Authors: Schmitt Evelyne
Published: March 2024

Michel Tourniers Ostpreußen.

Die deutschen Schriftsteller aus den ehemaligen Ostgebieten evozieren das Land der Kindheit unter dem doppelten Zeichen der Sehnsucht und der Schuld. Durch seine «Umschreibung» («réécriture») verfährt Michel Tournier in Le Roi des Aulnes nicht viel anders. Er bearbeitet eine Landschaft, die schon in der Phantasie des Lesers besteht und skizziert die beiden «Profile» Deutschlands. Ostpreußen, wo Mythos und Geschichte, Mensch und Natur aufeinandertreffen, ist das Land, in welchem Abel Tiffauges sich auf die Suche nach dem eigenen Ursprung machen kann. Die Provinz erscheint als eine in sich geschlossene Welt, wo sich Tourniers große Themen entwickeln können.
La chanson nationaliste de 1871 à 1914 ou la chanson d’une guerre à l’autre
Authors: Rassendren Yves
Published: March 2024

La guerre de 1870 et ses répercussions déclenchent en France une vive réaction nationaliste dont la chanson sera le miroir mais aussi la sève. S’inscrivant dans la tradition des chansons politiques, la chanson nationaliste, exacerbe les sentiments revanchards et alimente la haine de l’ennemi.

Par des moyens simplistes mais efficaces, timbres déjà connus, paroles percutantes ou larmoyantes, ce genre devient un outil politique aux fins parfois xénophobes ou antisémites et connaîtra des avatars jusqu’après la Première Guerre mondiale.
« Quand Madelon » et « Lili Marleen ». Ce que disent les chansons...
Authors: Genton François
Published: March 2024

Deux chansons créées dans l'indifférence en temps de paix, devenues populaires grâce à la guerre. L’une demeure surtout une musique de fanfare, l’autre reste universellement connue. Deux ans seulement séparent la rédaction des textes de « Quand Madelon » (1913) et de « Lili Marleen » (1915). Ce n’est pas beaucoup, mais en 1915 le « court XXe siècle » a été enfanté par la Première Guerre mondiale. « Lili Marleen » rend compte de l’atomisation et de la détresse du soldat des temps modernes tandis que « Quand Madelon » évoque une sociabilité d’un autre temps.
La critique du régime et de la guerre dans les chansons de l’époque hitlérienne
Authors: Schepping Wilhelm
Published: March 2024

Cette contribution rend compte, en les commentant, des résultats d’un projet de recherche de longue haleine dirigé par l’auteur à l’Institut d’ethnologie musicale de l’université de Cologne : il s’agissait d’étudier les chants d’opposition au nazisme durant le IIIe Reich. Conformément au sujet du colloque «La guerre en chansons», notre texte montre à partir d’exemples représentatifs qu’en Allemagne, parmi les multiples manifestations de critique ou de résistance, le fait de chanter des textes d’opposition, textes originaux, mais aussi parodies d’hymnes nationaux, de chants partisans, de chants d’église, de chansons du mouvement de jeunesse ou de chansons de variétés alors en vogue, représenta un moyen fréquent d’expression connotative et annotative de critique ou de résistance, et ainsi un instrument efficace de lutte contre le régime et la guerre, exposant ceux qui l’utilisèrent à une répression impitoyable.
Les connotations d'un hymne national « Réveille-toi, Roumain »
Authors: Melian Alexandru
Published: March 2024

L’exposé propose un double aperçu sur le thème en débat : d’une part, la guerre reflétée dans les chansons populaires (la dimension folklorique) et, d’autre part, les connotations guerrières, plutôt révolutionnaires, de l’hymne national roumain (la dimension culte) .

Tandis que les premières, — en valorisant la ligne mélodique de doina (une complainte spécifique à la musique populaire roumaine) — exprime la douleur de la séparation, le dor de tous ceux qui sont restés loin, la révolte contre la guerre et contre ceux qui l’ont provoquée, l’hymne national, — dans la tradition des chansons de caserne et révolutionnaires, avec leur rythme de marche — transmet l’hommage à la liberté nationale et l’appel contre la tyrannie, contre l’esclavage.

L’analyse du verbe a(se)destepta met en évidence des ouvertures sémantiques qui expliquent la pérennité de cette chanson, devenue hymne national.
Max Reinhardt aux USA. Expériences théâtrales et cinématographiques. Histoire d’un rêve américain
Authors: Thivat Patricia-Laure
Published: March 2024

L’histoire de l’exil de Max Reinhardt est complexe. L’artiste réalise des tournées aux USA dès 1912. Les points forts de son activité aux USA furent la mise en scène grandiose du Songe d’une nuit d’été en 1934 à Hollywood, puis la réalisation du film inspiré de cet événement en 1935. Dès 1934 Reinhardt avait entrepris des démarches pour acquérir la nationalité américaine, qu’il n’obtint qu’en 1940, trois ans avant sa mort. Chassé d’Autriche par 1’Anschluss, il créa à Hollywood une école à l’image de celles qu’il avait fondées en Europe et confirma son rôle de découvreur de stars. Son autre grand projet, donner naissance entre New York et Hollywood à l’équivalent de la constellation Berlin/Salzbourg/Vienne, ne put se réaliser. Reinhardt était-il encore trop européen ?
Le mythe habsbourgeois de la coexistence harmonieuse des nationalités et ses principes antagonistes. Le colonialisme et le nationalisme
Authors: Le Rider Jacques
Published: March 2024

Der Habsburgermythos von der harmonischen Koexistenz der Nationalitäten und seine antagonistischen Prinzipien: Kolonialismus und Nationalismus.

Für den ganzen Donauraum hatte die territoriale Expansion der Habsburger Monarchie in Folge der Kriege gegen die Türken und später der Polen-Aufteilung zwischen Österreich, Preußen und Russland eine vereinheitlichende, im regionalen Sinne des Wortes ,,globalisierende Funktion“. Das Ost-West-Gefälle wurde ab dem letzten Drittel des 19. Jahrhunderts tendenziell geringer.

Zugleich aber brachte die „Globalisierung“ innerhalb des habsburgischen Donauraums neue soziale Ausdifferenzierungen und gesellschaftliche Diskurse quasi-kolonialen Typs. Die nationalen Ideologien versprachen als Reaktion auf die „zivilisatorische Herrschaft“ der Habsburger eine gesicherte Existenzform in neu zu konstruierenden, „imaginären Gemeinschaften.“

Diese historische Ambivalenz prägt die historische Erbschaft der Habsburger Monarchie: Einerseits war sie als integrierende und „globalisierende“ Imperialmacht ein Laboratorium für die Gegenwart, die in der Osterweiterung der EU eine vorrangige Aufgabe erblickt; andererseits war sie die „Versuchsstation des Weltuntergangs“ (Karl Kraus), in diesem Falle des Umschwungs von Globalisierung in den allgemeinen Kampf der kulturellen Identitäten.
La transposition littéraire des conflits en Bucovine. L’Hermine souillée de Gregor von Rezzori
Authors: Lehmann Marie
Published: March 2024

Dans son roman L’Hermine souillée qu’il dédie à la ville de son enfance, Gregor von Rezzori déconstruit le topos de la « civilisation de Czernowitz » en décrivant les tensions nationalistes, l’instrumentalisation de la langue et l’antisémitisme qui ruinent après la Première Guerre mondiale le principe de pluriculturalité censé servir de fondement à une communauté dont les membres font l’expérience d’une désorientation et d’un délitement. Le pluriel se vit sur le mode de la déchirure, d’une tension qui s’accentue pour finalement aboutir à une logique d’exclusion et de marginalisation. Le choix de l’ironie et de la satire qu’il utilise tant contre les responsables du crépuscule de Czernowitz que contre les partisans d’une relecture du passé synonyme de mythification permet à l’auteur de revendiquer son héritage mitteleuropéen dont il retient la fragilité et les contradictions.
La persécution nazie et fasciste des Roms
Authors: Boursier Giovanna
Published: March 2024

Comme c’est le cas pour la France, l’Italie a interné les Tsiganes au cours de la Seconde guerre mondiale. Ces mesures s’inscrivent dans la logique d’une politique répressive à l’égard des Tsiganes définie dès 1926. La question de savoir si la politique anti-tsigane du régime de Mussolini était d’inspiration raciste fait débat. En revanche, il ne fait pas de doute qu’à partir des camps de l’Italie fasciste, des Tsiganes ont été déportés en Allemagne.
Le Saint-Siège dans la Seconde Guerre mondiale et face à l’internement
Authors: Ferrari Liliana
Published: March 2024

Les interventions du Saint-Siège vis-à-vis des internés des camps italiens sont à considérer dans le cadre de sa politique de neutralité et de médiation au cours des années de guerre. Un bureau d’information, dirigé par Giovambattista Montini, le futur Paul VI, centralisera les activités d’assistance. Elles sont multiformes, comme l’est la population des camps italiens : militaires, ressortissants des pays ennemis, Juifs étrangers, internés civils yougoslaves. Pour l’Église, l’internement n’est ni bon ni mauvais : il est. La ligne de conduite du Saint-Siège se maintiendra sur la double voie de la prudence et de la sollicitude.
Adaptation et métamorphose : un Heimatverein westphalien à l’épreuve de la modernité (1949-1961)
Authors: Gladieux Marc
Published: March 2024

Le Sauerländischer Gebirgsverein (SGV) se définit lui-même comme un «Heimat- und Gebirgsverein» et jouit d’un succès croissant dès sa création à Arnsberg en 1891. Cette association, dont l’organe diffuse des thèses à certains égards très proches du nazisme, fut relativement épargnée par la « mise au pas » de 1933. Or, après l’effondrement du IIIe Reich, le SGV vit une renaissance qui se traduit par un grand nombre d’adhérents. Comment l’association est-elle parvenue à s’adapter à la nouvelle donne sans renier son propre passé ? Comment a-t-elle réussi à concilier les slogans raisonnablement identitaires de l’après-guerre et les positions antérieures à 1945 ? La communication montre qu’elle s’est vue contrainte d’opérer une mue idéologique sous l’effet de la nationale, de la crise berlinoise et surtout du « miracle économique » à la fin des années 1950. C’est cette nécessaire évolution qui lui a permis d’entrer dans la modernité.
Fessenheim, ou l’exemple d’un combat pour la Heimat
Authors: Simon Dominique
Published: March 2024

Au début des années 1970, une contestation voit le jour dans un triangle situé entre le pays de Bade, l’Alsace et la Suisse alémanique. Des manifestants possédant une langue et culture très proches protestent contre la construction de la centrale nucléaire de Fessenheim. Au fil du temps des contacts étroits s’établissent entre les trois pays. Les manifestants ont trouvé un objectif commun : se mobiliser pour la protection et la défense de leur patrie, même si l’intensité du combat et les moyens mis en oeuvre ne sont pas les mêmes des deux côtés du Rhin.
Heimatdichterin ou l’ambivalence d’un concept : le cas d’Annette von Droste-Hülshoff
Authors: Marchenoir Sylvie
Published: March 2024

Dans les histoires de la littérature allemande et les anthologies, Annette von Droste-Hülshoff a très longtemps fait l’objet d’un classement parmi les poètes ayant chanté leur pays natal, les Heimatdichter. Une grande partie de son œuvre évoque en effet sa région d’origine, la Westphalie, que la poétesse décrit avec minutie, parfois sans complaisance, mais aussi avec humour, laissant transparaître un attachement sans faille à la terre de ses ancêtres. Mais, dans la seconde moitié du XIXe siècle et la première moitié du XXe siècle, ce régionalisme tombe sous le coup d’une critique qui en relève les limites. Cette poésie du terroir, trop attachée au concret et au détail au prix d’une certaine confusion et d’une absence de construction, est censée manquer d’envergure, de spiritualité et d’universalité. Outre que cela revient à ignorer de larges pans de la création artistique d’Annette von Droste-Hülshoff comme la poésie religieuse, les épopées en vers ou le lyrisme des dernières années, cette accusation vise à dénigrer une poésie originale et novatrice, l’oeuvre d’une femme de génie ne relevant d’aucune école littéraire. La dévalorisation du concept Heimatdichterin fournit un bel exemple du mépris avec lequel on a longtemps traité la littérature féminine.
L’ambiguïté de la notion de Heimat dans le roman de Siegfried Lenz Heimatmuseum
Authors: Merchiers Dorle
Published: March 2024

Siegfried Lenz fait partie de ces auteurs allemands qui, comme Christa Wolf, Johannes Bobrowski, Walter Kempowski, Horst Bienek et bien d’autres, sont nés entre 1925 et 1935 dans des régions auxquelles l’Allemagne dut renoncer au lendemain de la Seconde Guerre mondiale. Ces écrivains ressuscitent dans leurs œuvres la terre de leur enfance, qu’ils ont souvent dû quitter dans des circonstances dramatiques. Dans son roman Heimatmuseum, paru en 1978, Lenz brosse une vaste fresque de la Mazurie, tout en démontrant l’ambiguïté que revêt pour le lecteur allemand la notion de Heimat, tantôt synonyme d’espace idyllique où l’individu trouve ses racines, son identité et son épanouissement, tantôt synonyme d’esprit provincial et de patriotisme local, susceptible d’engendrer chauvinisme et nationalisme, surtout quand elle est utilisée par des idéologues et des stratèges. L’auteur invite le lecteur à considérer le double visage de la « terre natale », afin de mieux l’aider à dépasser cette antithèse et à s’interroger sur le sens qu’il convient d’accorder à la notion de Heimat dans le monde contemporain.
« Heureux qui comme [Ambros] a fait un long voyage » ou : « Ambros Adelwarth » et le pays natal dans Les Émigrants de W. G. Sebald
Authors: Carré Martine
Published: March 2024

Ambros Adelwart, personnage éponyme du troisième récit des Émigrants, est né en Allemagne. Il quitte enfant son pays natal pour des raisons économiques. Il mène alors la vie d’un Picaro des temps modernes avant de s’installer, après de longues années d’errance, aux États-Unis. C’est là qu’il mourra dans la clinique « Samaria » de la ville d’Ithaca (N. Y.). L’analyse repose sur une étude des noms (prénoms, patronymes et toponymes) et fait apparaître qu’Ambros, sujet en apparence parfaitement cosmopolite, a cherché sa vie durant un pays natal qu’il lui faut identifier, en arrivant à Ithaca, comme « pays natal ennemi » – Feindheimat pour reprendre l’expression de Jean Améry. L’Odyssée et l’essai de Jean Améry Wieviel Heimat braucht der Mensch? sont lus ici (entre autres) comme hypotextes du récit.
La petite patrie sur la frontière. L’impact des dialectes en Sarre et en Lorraine dite « francique » dans la construction de l’identité culturelle de leurs locuteurs
Authors: Bodé-Pitz Martina
Published: March 2024

La forte ressemblance des dialectes de l’Est mosellan et de la Sarre semble évidente. Il est néanmoins indéniable qu’en fonction de leur lieu de résidence au sein de cet espace frontalier, les locuteurs ne partagent pas la même perception de ces variétés linguistiques bien que celles-ci soient généralement ressenties comme le « vecteur de base » fondant l’identité culturelle des différents « petits pays ». S’appuyant sur quelques sources littéraires mettant en lumière ces discordances, cette contribution tente de traquer les diverses perceptions de cette « petite patrie » de part et d’autre des frontières actuelles.
Une Bavière revisitée : le « nouveau » Heimatfilm
Authors: Guillard Gilbert
Published: March 2024

Zurück nach Bayern: der „neue“ Heimatfilm.

Im Zuge des „jungen deutschen Films“ der sechziger Jahre drehen Regisseure sogenannte neue Heimatfilme, die sowohl eine politisch-soziale Kritik wie eine ästhetische Revolution bezwecken. „Neu“ bedeutet jedoch nicht Erneuerung, sondern Demontage (Anti-Heimatfilm). Es geht darum, anders zu filmen und den reaktionären Diskurs des Heimatfilms und deren Hersteller bloßzustellen. Jagdszenen in Niederbayern von Peter Fleischmann (1968) ist nicht nur eine Darstellung, im Sinne der Karikatur, der Sitten und sozialen, politischen und religiösen Ideologie des ländlichen Bayerns, sondern auch eine allgemeine Infragestellung der modernen Gesellschaft. Die Themen (Gastarbeiter, Stellung der Frau, Homosexualität) werden so behandelt, daß die auf Gewalt begründete Art und Weise, wie eine doppelbödige Gemeinschaft funktioniert, dargelegt wird, auch um zu zeigen, daß der Begriff Heimat eigentlich keine höhere Werte beinhaltet.
