WASTAGE AND STAGNATION OF GOVERNMENT PRIMARY SCHOOLS IN MANIPUR: A CRITICAL ANALYSIS
Authors:   Assistant Professor, Department of Education, Thoubal College, Thoubal, Manipur, India, Singh Dr. R. Vikas
Published: June 2023

Wastage and stagnation in government primary schools have been persistent concerns in the educational landscape of Manipur. This critical analysis aims to examine the causes and consequences of wastage and stagnation in government primary schools, shedding light on the complex factors that contribute to these issues. Through a comprehensive review of relevant literature and analysis of available data, this study explores the underlying causes of wastage and stagnation in government primary schools in Manipur. Factors such as low enrolment rates, high dropout rates, inadequate infrastructure, teacher shortages, and socio-economic disparities are identified as key contributors to the problem. Additionally, cultural and linguistic factors, lack of parental involvement, and ineffective pedagogical practices are also examined. The consequences of wastage and stagnation in government primary schools are multifaceted and far-reaching. Students who drop out or repeat grades are at a disadvantage in terms of their educational attainment and future prospects. The educational system as a whole suffers from inefficiencies and a lack of skilled human capital. The long-term socio-economic development of Manipur is hindered by the perpetuation of an undereducated workforce. To address these issues, a comprehensive approach is necessary. Strategies such as improving access to quality education, enhancing teacher training and support, strengthening community engagement, and addressing socio-economic disparities are crucial. Furthermore, the development and implementation of evidence-based policies and interventions tailored to the specific needs of Manipur's government primary schools are essential. This critical analysis emphasizes the urgency of addressing wastage and stagnation in government primary schools in Manipur. It highlights the need for collaborative efforts among government bodies, educational institutions, communities, and stakeholders to tackle this complex issue. By investing in the improvement of primary education, Manipur can nurture a generation of well-educated individuals equipped with the skills necessary for their personal growth and the overall development of the state. Further research should focus on evaluating the effectiveness of specific interventions aimed at reducing wastage and stagnation in government primary schools. Longitudinal studies tracking the educational trajectories of students and examining the long-term outcomes of interventions would provide valuable insights into the effectiveness of various strategies.

Authors: Maresch Günter , Caballero Natalia Segura , Köck Julia , Lagoudaki Eleni
Published: June 2023

Spatial ability plays a critical role in developing expertise in Mathema tics and STEM fields in general. Therefore, we (15 geometry researchers and 15students in Austria) developed the online platform RIF (https://adi3d.at/rif30/en/)where students from the age of 7 to adulthood can train their spatial thinking skills with the help of more than 1.500 interactive tasks. All the tasks are designed in such a way that they can directly be integrated into school lessons and university lectures. The platform, which is free to use for everybody, was launched in 2019 and today more than 60.000 students from 28 countries all over the world use the platform. The large amount of data allows to do a lot of research. In the talk results regarding gender differences and the correlation of spatial ability and mathematics will be presented. The analyses of the data show that girls perform better than boys in nearly all areas of spatial ability and that there is a strong correlation between spatial thinking skills and the math grade of primary and secondary students.
A Technology-oriented Algebra Curriculum
Authors: Oldenburg Reinhard
Published: June 2023

The traditional algebra curriculum of (lower) secondary schools is (at least in Germany) plagued by several severe deficits: 1) Students are hardly interested and motivated to learn algebra. 2) The semantics of algebra as discussed in didactics is unnecessary complex and partially incompatible with algebra in upper secondary schools and at the university level. 3) The algebra taught is partly incompatible with the algebra of programming languages and computer algebra systems. This paper gives a short overview of a technology-oriented curriculum that shall overcome these issues and it presents some of the technological tools that have been developed to provide a consistent and motivating learning experience of algebra. An essential feature is that technology is not just a medium, but a tool and benchmark for consistency.
S3D Approach: Strategies and Tools for Fostering Equitable Small-Group, Student-to-Student Discourse
Authors: Quebec Fuentes Sarah
Published: June 2023

Placing students in small groups does not automatically imply that the students will be able to productively interact with each other about the mathematics. The S3D Approach is a two-phase process through which educators can progress to improve small-group, student-to-student discussions in their mathematics classes. In the first phase, educators evaluate existing smallgroup discourse via three lenses (group dynamics, discourse quality, and teacher support). In the second phase, educators use what they learned in Phase 1 to enhance the small-group discourse through purposeful teacher actions. Tools are associated with each lens of Phase 1 as well as Phase 2 to assist educators in recording their observations. The S3D Approach helps establish norms of a safe classroom where students contribute their thinking, through which a shared understanding of mathematical justification is built.
Everywhere and Nowhere…All at Once
Authors: Clint Whitten
Published: June 2023

Following the tragedy of another shooting that happened in a visibly Queer space, this study explores how Queerness in rural spaces generates a spectrum of visibility. Men in Place (2019) by Miriam Abelson and Out in the Country: Youth Media and Queer Visibility in Rural America (2009) by Mary Gray, personal narratives/podcasts cultivated by Country Queers, and “place histories” such as Brandon Teena and Matthew Shepard which were highly visible cases of rural Queer overkill, are used as objects of study to explore the role and function of visibility in rural contexts. After exploring these rural Queer-centric narratives, I generated three thematic categories: working to preserve Queer comfort in rural spaces, identity work of rural Queerness, and fears and spaces of violence. I conclude by using the three categories to offer three implications for educational practices to complicate our understanding of Queer visibility in rural schools.

A Christian Expression of African Spirituality: The Case Study of Three African Initiated Churches in Ghana
Authors: Afriyie Ernestina
Published: June 2023

There is a view that African Instituted Churches (AICs) are Christian churches with a spirituality which is similar to traditional spirituality. Scholars have claimed that AICs came up as a response to the spirituality of the churches started by missionaries from the West. The latter churches seemed to ignore the spiritual world, the activities of the Spirit and also the fact that physical occurrences have spiritual causes. As such, the spiritual needs of African converts were not being met. In research to ascertain the validity of this assertion, this researcher looks into the circumstances surrounding the founding of AICs in Ghana, paying particular attention to the Church of the Twelve Apostles, the OSSAH-Madih Church, and the Musama Disco Christo Church. The research was done through participant observations in the AICs mentioned. Secondary data was gathered from articles, books and other research materials written by members of AICs. The research concluded that while some AICs may have started as a reaction to the operation of the mission churches, the spirituality expressed is not a “copying” of African spirituality, but one that comes about with the awareness of the existence of the spiritual realm.

Which Component of Solar Magnetic Field Drives the Evolution of Interplanetary Magnetic Field over the Solar Cycle?
Authors: Yoshida Minami , Shimizu Toshifumi , Toriumi Shin
Published: June 2023

The solar magnetic structure changes over the solar cycle. It has a dipole structure during solar minimum, where the open flux extends mainly from the polar regions into the interplanetary space. During maximum, a complex structure is formed with low-latitude active regions and weakened polar fields, resulting in spread open field regions. However, the components of the solar magnetic field that are responsible for long-term variations in the interplanetary magnetic field (IMF) are not clear, and the IMF strength estimated based on the solar magnetic field is known to be underestimated by a factor of 3–4 against the actual in situ observations (the open flux problem). To this end, we decomposed the coronal magnetic field into the components of the spherical harmonic function of degree and order (ℓ, m) using the potential field source surface model with synoptic maps from SDO/HMI for 2010–2021. As a result, we found that the IMF rapidly increased in 2014 December (7 months after the solar maximum), which coincided with the increase in the equatorial dipole, (ℓ, m) = (1, ±1), corresponding to the diffusion of active regions toward the poles and in the longitudinal direction. The IMF gradually decreased until 2019 December (solar minimum) and its variation corresponded to that of the nondipole component ℓ ≥ 2. Our results suggest that the understanding of the open flux problem may be improved by focusing on the equatorial dipole and the nondipole component and that the influence of the polar magnetic field is less significant.

The power spectrum of magnetic field fluctuations in the fast solar wind (V
SW > 500 km s−1) at magnetohydrodynamic scales is characterized by two different power laws on either side of a break frequency f
b. The low-frequency range at frequencies f smaller than f
b is often viewed as the energy reservoir that feeds the turbulent cascade at f > f
b. At heliocentric distances r exceeding 60 solar radii (R
s), the power spectrum often has a 1/f scaling at f < f
b, i.e., the spectral index is close to −1. In this study, measurements from the Parker Solar Probe's Encounter 10 with the Sun are used to investigate the evolution of the magnetic field power spectrum at f < f
b at r < 60 R
s during a fast radial scan of a single fast-solar-wind stream. We find that the spectral index in the low-frequency part of the spectrum decreases from approximately −0.61 to −0.94 as r increases from 17.4 to 45.7 R
s. Our results suggest that the 1/f spectrum that is often seen at large r in the fast solar wind is not produced at the Sun, but instead develops dynamically as the wind expands outward from the corona into the interplanetary medium.

We report the detection of very high energy gamma-ray emission from the blazar S3 1227+25 (VER J1230+253) with the Very Energetic Radiation Imaging Telescope Array System (VERITAS). VERITAS observations of the source were triggered by the detection of a hard-spectrum GeV flare on 2015 May 15 with the Fermi-Large Area Telescope (LAT). A combined 5 hr VERITAS exposure on May 16 and 18 resulted in a strong 13σ detection with a differential photon spectral index, Γ = 3.8 ± 0.4, and a flux level at 9% of the Crab Nebula above 120 GeV. This also triggered target-of-opportunity observations with Swift, optical photometry, polarimetry, and radio measurements, also presented in this work, in addition to the VERITAS and Fermi-LAT data. A temporal analysis of the gamma-ray flux during this period finds evidence of a shortest variability timescale of τ
obs = 6.2 ± 0.9 hr, indicating emission from compact regions within the jet, and the combined gamma-ray spectrum shows no strong evidence of a spectral cutoff. An investigation into correlations between the multiwavelength observations found evidence of optical and gamma-ray correlations, suggesting a single-zone model of emission. Finally, the multiwavelength spectral energy distribution is well described by a simple one-zone leptonic synchrotron self-Compton radiation model.
Universal Multistream Radial Structures of Cold Dark Matter Halos
Authors: Enomoto Yohsuke , Nishimichi Takahiro , Taruya Atsushi
Published: June 2023

Virialized halos of cold dark matter generically exhibit multistream structures of accreted dark matter within an outermost radial caustic known as the splashback radius. By tracking the particle trajectories that accrete onto the halos in cosmological N-body simulations, we count their number of apocenter passages (p) and use them to characterize the multistream structure of dark matter particles. We find that the radial density profile for each stream, classified by the number of apocenter passages, exhibits universal features and can be described by a double power-law function comprising shallow inner slopes and steep outer slopes of indices of −1 and −8, respectively. Surprisingly, these properties hold over a wide range of halo masses. The double power-law feature is persistent when dividing the sample by concentration or accretion rate. The dependence of the characteristic scale and amplitude of the profile on p cannot be replicated by known self-similar solutions, requiring consideration of complexities such as the distribution of angular momentum or mergers.
Distance Duality Test: The Evolution of Radio Sources Mimics a Nonexpanding Universe
Authors: Li Pengfei
Published: June 2023

Distance duality relation (DDR) marks a fundamental difference between expanding and nonexpanding universes, as an expanding metric causes angular diameter distance smaller than luminosity distance by an extra factor of (1 + z). Here we report a test of this relation using two independent samples of ultracompact radio sources observed at 2.29 GHz and 5.0 GHz. The test with radio sources involves only geometry, so it is independent of cosmological models. Since the observed radio luminosities systematically increase with redshift, we do not assume a constant source size. Instead, we start with assuming the intensive property, luminosity density, does not evolve with redshift and then infer its evolution from the resultant DDR. We make the same assumption for both samples, and find it results in the same angular size–redshift relation. Interestingly, the resultant DDR is fully consistent with a nonexpanding universe. Imposing the DDR predicted by the expanding universe, we infer the radio luminosity density evolves as ρ

L
∝ (1 + z)3. However, the perfect agreement with a nonexpanding universe under the assumption of constant luminosity densities poses a conspiracy and fine-tuning problem: the size and luminosity density of ultracompact radio sources evolve in the way that precisely mimics a nonexpanding universe.
The koala retrovirus: lessons learned from the koala genome. In Proceedings of the Second Koala Retrovirus Workshop, ed. D. E. Alquezar-Planas, D. P. Higgins, C. L. Singleton, and A. D. Greenwood
Authors: Alquezar-Planas David E.
Published: June 2023

The establishment of the Koala Genome Consortium in 2013 culminated in the publication of the first fully assembled koala genome. An international initiative involving 29 institutes across the globe, the publication has led to a much greater understanding of koala biology including knowledge on gene families putatively associated with detoxification of eucalypt leaves and the species’ ability to taste and smell plant secondary metabolites. Similarly, the genomic resource has enabled comparative assessments facilitating immunogenomics, population genomic analysis, and, for the first time, genome-wide assessments of the koala retrovirus (KoRV). This summary outlines how the koala genome has increased our capacity to understand the genetics of KoRV—from a deeper understanding of KoRV viral subtypes and their recombinants to preferences for viral integration across the host genome.
Putative koala retrovirus-associated diseases in the Japanese captive koala (Phascolarctos cinereus) population. In Proceedings of the Second Koala Retrovirus Workshop, ed. D. E. Alquezar-Planas, D. P. Higgins, C. L. Singleton, and A. D. Greenwood
Authors: Imanishi Tetsuya
Published: June 2023

Japan began housing koalas (Phascolarctos cinereus) in 1984, increasing from six individuals in 1984 to a peak of 96 koalas in 1997. However, the number of koalas has almost halved since and as of 2020, 54 koalas remain in zoos in Japan. Although records of 330 koala deaths have been accumulated over 37 years, there have been no comprehensive reports on the relationship between the causes of death and koala retrovirus (KoRV) in the Japanese captive population. Based on the koala studbook updated by the Japanese Association of Zoos and Aquariums, we have investigated causes of death in the Japanese captive koala population. The most common cause of death was joeys falling. When combined with stunted joey growth, one-third of the koalas died within a year of birth. Deaths due to malignant neoplasms and opportunistic infections cannot be directly associated with KoRV infection because no test for KoRV had been performed before or during disease onset. It is suspected that KoRV may be associated with deaths due to the large number of cases of neoplasms, which accounted for 16.4% of all deaths.

About the formation of Hridsko lake in Bogićevica Mountains, Montenegro
Authors: Gachev Emil , Djurović Predrag , Stoyanov Krasimir , Bezinskа Galina , Ivanov Miroslav , Petrov Stefan
Published: June 2023

The article presents the latest views about the origin of Hridsko lake in the mountain range Bogicevica, an eastern part of Prokletije massif (Dinaric range). Previous studies define the lake, which is situated at 1980 m a. s. l., and occupies an area about 3,5 ha, as a cirque lake, formed after the retreat of wuermian glaciers following the classical mechanism of glacial lakes formation. In result of our researches, which started in 2013, a new hypothesis evolved that the lake lies inside a large relict rock glacier, formed in the period after the termination of glaciers, which means that the lake depression has a rather periglacial origin. The new bathymetry mapping of the lake done in 2017 provides a support to this hypothesis.
Mapping of burned area and assessment of burn severity of the 2017 wild fires in Kresna gorge
Authors: Gikov Alexander , Dimitrov Petar
Published: June 2023

At the end of the summer of 2017, the weather in Bulgaria was very dry and hot and this contributed for the occurrence of a series of wild fires. The largest and most prolonged was the wild fire that raged in Kresna gorge. The fire broke out on August 24 and lasted for nearly a week. The aim of the paper is to make an assessment of the damage caused by the August fire and by a smaller wild fire in the same region, which broke out on July 13, 2017. The assessment is based on images from the satellites Sentinel-2A and -2B. For the identification and mapping of burned areas the spectral indices NBR (Normalized Burn Ratio) and dNBR (difference NBR) were used. Map of burn severity within the fire perimeter was compiled by reclassifying the dNBR values into three classes. The total burned area was 2199.1 ha; of this, the August fire covered 96%. The greatest part of the fire scar, over 50% of the area, is characterized with medium burn severity (dNBR between 0.27 and 0.66). Both, the lowest (dNBR between 0.1 and 0.27) and highest (dNBR>0.66) burn severity levels covered about ¼ of the total burned area. A map of the major land cover types in the study area was prepared in order to assess the most severely affected land cover types. The map is derived from supervised SVM (Support Vector Machine) classification of a Sentinel-2B image acquired before the fires. It was found that the coniferous forest class is dominated by the highest burn severity level (43.7% of the area). In the broadleaf forest class the areas with the lowest level of burn severity prevail (53.5%). The main reason is that coniferous forests in the study area represent artificial plantations created at altitude lower than the usual altitude of coniferous species in the region. Therefore they are much more susceptible to fire than broadleaf species which are native to the oak belt.

Published: June 2023

Investigation on the public opinion of people in the Smolyan region focuses on determining the public awareness of sustainable development (SD) and the policies related to it, on the one hand, as well as finding out if the people from this region take actions, corresponding to SD, without associating them with it, on the other hand. The article also contributes to revealing the barriers which arise with the implementation of SD, being laid down in the Regional Strategy for Development of the Smolyan Region for 2014-2025. The research toolkit includes a survey (on-line), using Google’s functions of data collection and processing. To come to the most adequate and applicable conclusions on mountain regional development, the territorial scope of the study is based on the idea that a "region" is considered to be a mountainous territorial system within an area that includes all mountainous municipalities according to all typologies.
Large-scale mapping and analysis of changes in contemporary landscapes over a 50-year period in the key area "Bogdaia", northwestern Rila Mountains
Authors: Gikov Alexander
Published: June 2023

Maps of contemporary landscapes for 1966, 1980, 1997 and 2016 in key area "Bogdaia" have been made by processing and visual interpretation of historical aerial photographs and recent satellite imagery. The identified changes in the study area show that there is a clear trend of increasing the area of forest landscapes and decreasing the area of grass landscapes which are of secondary origin. For the same period, the transitional forest-shrub landscapes show fluctuations without a clear trend. The restoration of natural forest landscapes is explained by the changed land use and the almost complete lack of grazing in recent years. The process of natural forest landscapes restoration is more active in the coniferous landscape belt and on slopes with northern exposure while in the lower deciduous belt and on slopes with southern exposure component it is slower.

Examples of 21st century political propaganda through caricature maps of Brexit are also discussed.
Air quality management in Vidin
Authors: Petrov Stefan , Drenovski Ivan
Published: June 2023

Air as a component of the natural environment is subjected to constant pollution caused by anthropogenic impact. Air can be considered polluted when the concentration of pollutants is higher than in a normal environment and this leads to a deterioration of the ambient air quality. This problem is also relevant for the region of Vidin and the town of Vidin in particular. Every year the city holds one of the highest ranks for the most polluted air in Bulgaria, even though the city has not been a place with a developed industrial activity that can be linked to air pollution for years. This report aims at identifying the causes of pollution and whether the measures taken in the “Programme for reducing the levels of PM10 and reaching the established norms of their content in the air in the region of Vidin for the period 2015-2020” are effectively implemented.

The term synergetic is proposed by the german physicist Henry Hacken as the name of a new interdisciplinary scientific field studying the processes of origin and evolution of space-time structures. The main task of synergetics is to reveal the general ideas, methods and patterns of self-organization processes in various fields of science - from nature science to the humanities. Synergetics seeks to reveal the internal mechanisms of self-organization, the general laws of these processes, their synergy. In landscape synergetics, the problem of time is related to the irreversibility of processes, which leads to the idea of instability and chaos. In this regard, the present study is aimed at exploring the possibility of using the synergetic approach in landscape research, and in particular in the study of self-restoration of landscapes after the weakening of anthropogenization.

The lead cooled reactor BREST-OD-300 is developing as a part of Russian federal project “PRORYV”. Two- circuit scheme is used in the reactor for heat removal. An inherent risk of two- circuit reactor is the potential danger of water steam ingression in the core in the case of large leakage in steam generator initiated, for example, Steam Generator Tube Rupture (SGTR).

Reactor power and temperature response on vapor penetration to the core is studied, but pressurization effects are not in the purview of the paper.

The 3D multi-physics (neutronics + thermal-hydraulics) UNICO-2F code was developed for study of SGTR accident. The code calculates unsteady 3D space dependent distributions of coolant velocity, pressure and temperature, space distributions of vapor concentration and heat release density in the core and 3D temperature distributions in the fuel pins.

Guillotine rupture of one tube in Steam Generator (SG) is considered as initial event of the accident.

It is shown that even with the most conservative assumptions reactivity insertion due to vapor ingress in the core causes small increase of power in level and as a result maximum cladding temperature continue to stay well below safe operation design limit in the entire transient.

Hypothetical option of simultaneous tube rupture in few SG belonging to different loops is also analyzed. It is demonstrated that even in the case of simultaneous large leak in two SG the transient stays mild and temperature in the core after two small oscillations is stabilized at acceptable level.

In the long term the analysis confirmed the high level of reactor self-protection against SGTR accident.
Le train de nuit, un miroir de l’évolution de l’intervention de l’État français dans le transport ferroviaire de 1980 à 2022

Le train de nuit est un objet particulier dans le paysage ferroviaire français : un service de moyenne et longue distance opéré la nuit dont l’État est autorité organisatrice. Son histoire tourmentée ces dernières années invite à analyser les enjeux de la relance de ce service dans un contexte de décarbonisation des transports, de promotion de l’aménagement du territoire et du rôle que peut jouer la puissance publique, l’État en particulier. La méthodologie mixte associe des données qualitatives issues d’entretien semi-directifs auprès d’acteurs (État, SNCF, région, association de défense) directement liés au train de nuit. Elle intègre également des informations quantitatives (lignes et gares desservies) dans l’objectif de caractériser les phases de déclin et relance de 1980 à 2022. À la lumière des principaux résultats, l’article souligne le rôle important de l’État dans l’évolution du service du train de nuit. Au cours d’une première phase (1980-2017), celui-ci s’est très largement désintéressé de ce service, la survie du train de nuit tenant au maintien de 2 lignes, dont une grâce au concours de la région Occitanie. Dans la phase suivante, la conjonction de plusieurs facteurs (préoccupations environnementales, équité territoriale, succès de l’offre ÖBB en Europe centrale) a entraîné une relance du service sous l’égide de l’État. Toutefois, malgré la remise en service de plusieurs lignes en direction du Sud de la France, de nombreux freins existent encore (travaux de modernisation du réseau, manque de matériel) et ne sauraient cacher une intervention de l’État dont la politique d’aménagement du territoire, sur le plan des transports interurbains, est en mal de substance.
L’Assemblée parlementaire franco-allemande : un nouvel acteur parlementaire sur la scène franco-allemande
Authors: Heimbach Henriette
Published: June 2023

Depuis 2019, les relations franco-allemandes disposent d’une nouvelle institution sans équivalent, l’Assemblée parlementaire franco-allemande (APFA), qui peut améliorer la concertation entre la France et l’Allemagne. Au moins deux fois par an, une centaine de députés au total, issus du Bundestag allemand et de l’Assemblée nationale française, se réunissent pour délibérer et pour auditionner des membres du gouvernement. Au cours de ses premières années de travail, l’Assemblée s’est imposée comme un acteur sérieux dans les relations franco-allemandes. Cet article décrit tout d’abord la genèse et le fonctionnement de l’Assemblée bilatérale, puis se penche sur deux défis politiques que l’APFA a relevés de manière différente. Lors de la pandémie de Covid-19, l’APFA a pu montrer sa valeur ajoutée et améliorer considérablement la coordination entre les gouvernements, notamment sur le thème de la fermeture des frontières. Il en va autrement dans le domaine de la politique étrangère, de sécurité et de défense, où la coopération au sein de l’APFA stagne.
La silhouette du mémorial australien de la guerre à Canberra
Authors: Gilfedder Deirdre
Published: June 2023

Cet article entend analyser la place que le monument national australien de la Première Guerre mondiale occupe dans la rhétorique urbaine de la capitale de l’Australie, Canberra. Le complexe commémoratif, The Australian War Memorial (AWM) a été édifié à un moment important dans l’histoire du pays et était destiné à perpétuer la mémoire des Australiens participant à la Grande Guerre. Qualifié de lieu de mémoire nationale, le mémorial est un musée et un monument aux 62 000 morts de l’Australian Imperial Force. L’article traite aussi de la tradition Anzac en Australie et son rôle dans la construction d’une notion singulière de nationalisme qui est lié à son statut de dominion au sein de l’Empire britannique. Combinant des styles architecturaux courants pendant la période entre-deux-guerres, le mémorial australien découpe une silhouette énigmatique au centre de la capitale du pays.
Plurilinguisme et créativité scientifique

La nécessité pour la science et l’enseignement universitaire d’avoir à disposition plusieurs langues est un impératif. Cependant, on a accordé, lors de la der-nière décennie, l’exclusivité à l’anglais pour les publications et les congrès internationaux, entraînant une éviction inquiétante de toutes les autres langues. Plus récemment, on observe même, depuis quelque temps, l’élimination de la langue nationale à l’intérieur même de l’espace linguistique allemand dans les domaines de la recherche et de l’enseignement universitaire. Non seulement les conférences internes et les congrès nationaux n’ayant que des participants de langue maternelle allemande ont lieu en anglais, mais encore, dans un nombre croissant de filières d’études universitaires, l’enseignement est dispensé en anglais. Pourtant, on a constaté que la limitation à un idiome unique simplifié dans l’acquisition de nouvelles connaissances porte préjudice à l’enseignement. Le but d’une politique linguistique active ne doit pas être la disparition de la langue nationale - surtout à l’intérieur même de son propre pays - au profit d’une « lingua franca », mais au contraire, dans l’esprit d’une pluralité de la pensée, elle doit stimuler les langues maternelles et, pour le moins, encourager une pluralité linguistique réceptive parmi les scientifiques. Nous donnerons quelques pistes qui pourraient permettre, nous l’espérons, de parvenir à ce but.
Plurilinguisme et créativité scientifique

Dans sa communication, Heinz Wismann évoque les bases philosophiques d’une pensée de la diversité en partant de l’œuvre du philosophe néokantien Heinrich Rickert. La pensée scientifique se développe autour de deux intérêts majeurs : le premier consiste à subsumer les cas particuliers sous des règles générales, c’est un processus de généralisation. Le second se porte sur le particulier selon un processus d’individualisation. Ces deux processus semblent caractériser d’une part les sciences de la nature, s’agissant de la généralisation, d’autre part les sciences de la culture, en ce qui concerne l’individualisation. Mais la distinction n’est pas aussi nette, la généralisation pouvant être pratiquée dans les sciences de la culture et l’individualisation dans les sciences de la nature.

Les écoles, les universités et les milieux d’affaires estiment que nous devons nous adapter au langage mondial du commerce et des transports. La peur assombrit la perception, une erreur plausible dans la pensée devient un fait accompli, tout simplement parce que le monde entier en parle. De plus, il y a la vanité: qui admettrait que leur anglais n’est pas suffisant ? Le droit à une communication misérable est par conséquent défendu de façon agressive, mais en fait la lingua franca n’est pas l’anglais, mais un mauvais anglais. L’anglomanie se fait aux dépens de la langue maternelle. Mais sans eux, il n’ y a pas d’acquisition réussie des langues étrangères. Le monde des affaires a besoin d’un langage de transport global codifié pour une communication sans erreur, tel que présenté par Jean Paul Nerrière dans “Don’ t Speak English - Parlez Globish! Le globisch est adapté à la communication dans la vie professionnelle et à la compréhension quotidienne des scientifiques. Cependant, les langues culturelles restent irremplaçables pour les échanges créatifs. Pour ce faire, nous avons besoin de traducteurs de haut niveau: ici, Globisch, là, l’expertise d’un traducteur. Ensuite, nous pourrons consacrer l’attention qu’elle mérite à notre langue maternelle et, sur cette base, nous pourrons nous réjouir des langues de nos voisins européens. Le multilinguisme n’est pas un obstacle, mais la force de l’Europe - nous devrions l’utiliser!

Ce qui est ici raconté et problématisé, c’est l’histoire de la constitution et de l’expansion du consortium ATR entre une société française d’aviation EADS et une société italienne Alenia Aermacchi, filiale à 100 de Finmecanica. Fusion des équipes et apprentissage de travailler ensemble, puis une expansion mondiale. Avec 4.000 employés, 15 nationalités, 10 langages, le plurilinguisme intrinsèque et stratégique de la société a été un des gage de son efficacité et de son succès.
