Welcoming One Another” (Romans 14-15): A Paradigm for Mutual Cooperation Among Christians in Nigeria
Authors: Jatau Paul Danbaki
Published: January 2024

Decades of discussions have occurred over whether Romans 14–15 is directed to any particular circumstance in the Roman community, as it contains arguments similar to those found in 1 Corinthians 8-10. Some scholars feel it is a generic admonition, while others say it is a reply to the Roman community's particular predicament. The concept of mutuality fits within the setting of Romans, and the chapters (Rom 14–15) speak of Paul's exhortations from the preceding chapters (Rom.12–13) being applied contextually. In Nigerian churches/Christianity, the scenario of separation and categorization found in the Roman Church exists. Certain Christians have been labeled as "weak" or "strong" as a result of this; ethnicity and other factors are most likely to blame. As a result, the negative effects exceeded the favorable effects among Christians over the last few decades. This paper examines Paul’s style for eliciting mutual collaboration (brother/sister metaphor), arguing that if Christians read, comprehend, and embrace Paul's call to welcome one another in Romans 14 –15, the walls of division will fall and mutual cooperation will ensue.
Human Capital Development and Industrial Sector Performance in Pre And Post Covid-19 Era: The Australian Experience
Authors: Akpoghelie Emmanuel Oghenekome , Chiadika Emmanuella Obiajulu
Published: January 2024

The importance of the ravaging pandemic on human development and industrial sector performance cannot be overemphasized. This is because an improved and quality industrial output is a function of quality human resources. This study explicitly examined the effects of the ravaging pandemic on human development and industrial sector performance in Australia during pre and post COVID-19 era. Human development was measured with the Human Development Index (HDI), Inequality Adjusted HDI (IHDI), Multi-dimensional Poverty Index (MPI) and the Gender Development Index (GDI) while the Earnings before Interest, Tax, Depreciation and Amortization (EBITDA) and the Industry Value Added (IVA) were used to capture the trend in Australia’s industrial sector performance during pre and post COVID-19 era. Data were sourced from Australian Bureau of Statistics (ABS), the United Nations Development (UNDP) Report and World Bank indicators. The study findings revealed, amongst others, that human quality was better off before the pandemic than after it and this was explicitly reflected in the country’s industrial output, as a better performance was recorded before the pandemic than after it. Australia, like China, needs more aggressive net zero CO2 emission policies including those relating human development to industrial output. Aggressive export diversification would help her economy recover faster from the adverse effects of the ravaging pandemic through effective and efficient utilization of her renewable energy sources.

The study examined leadership styles and attitude to work in formal organizations: A study of universities in South-South Nigeria. Two specific objectives and hypotheses were formulated for the study. The contingency and situational leadership theory was used to support the argument in the study. The cross sectional design was used for the study. The sample of 400 was derived from the population of 8054. Cronbach alpha was used to determine the reliability of the instrument with a reliability score of 0.59. The data were analysed through descriptive statistics such as mean and inferential statistics using the Pearson Product Moment Correlation (PPMC) to determine or establish the linear relationship between the independent and dependent variable in the study. The study revealed that autocratic leadership style does not elicit favourable attitude from workers toward work in Nigerian universities. The study also found that bureaucratic leadership style does not improve workers attitude to work in Nigerian universities. The study recommended that autocratic system of leadership should be discouraged from use in modern organisations as it has the capacity to de-motivate workers as established t=from the findings of the study. It also recommended that bureaucratic leadership style should be used in situational context and not as the only method in use to elicit a favourable attitude from workers.

Authors: ELbashir Bashir
Published: January 2024

The variety of cultures in educational institutions is expanding quickly. As a result, instructors' understanding of cultural background becomes a useful asset in how they run their classroom. This study sought to determine how instructors' classroom management relates to their cultural sensitivity. A correlational research design was used in the study. It is a quantitative study that also included interviews. A total of 30 participants who taught at three universities in Oman; namely A’ Sharqiyah University, Sohar University and the University of Technology and Applied Sciences during the academic year 2022–2023 were included in the study. Three (3) of the educators were chosen at random for an interview. Questionnaires were used to collect the necessary data following the survey method and teacher interviews were selected at random. Frequency count and percentage were used to examine the data. The study's findings showed that teachers exhibit a high level of cultural awareness. They made extensive use of optimal classroom management. A moderately significant association between cultural sensitivity and classroom management was also revealed by the research. According to the results, instructors' cultural sensitivity affects how they manage their classrooms. The study suggests teacher capacity-building initiatives, such as seminar-workshops on multicultural educational approaches and culturally sensitive classroom management techniques, to help teachers expand their expertise.

Published: January 2024

In present work, the effect of helical fins with height 20 mm and pitch 100 mm on the performance of the double pipe heat exchange investigated experimentally. The heat exchanger had been chosen as a heat recovery device in bricks factory to recover heat from exhaust gases to preheat the heavy fuel oil. Air had been chosen as a hot gas instead of furnace exhaust gases because of the similar thermal properties and it flows in the inner pipe with different velocity (20, 27, and 34) m/s and inlet temperature (200, 225) °C while, heavy fuel oil enters shell side with counter flow at mass flow rates (0.06, 0.08, and 0.1) kg/s and constant inlet temperature of 40 °C. Both of pipes and helical fins are made from stainless steel. The experimental results show that increasing Reynolds number from 139139 to 333934 led to increase heat transfer rate, oil outlet temperature, overall heat transfer coefficient and effectiveness of heat exchanger with (8%, 4%, 5% and 5%) respectively while, increasing oil mass flow rate from (0.06 to 0.1) kg/s cause decreasing oil outlet temperature and effectiveness of with (10% ,14%) respectively. The results shown the double pipe heat exchanger with helical fins produce heat transfer rate and oil outlet temperature higher than smooth double pipe heat with average 15% and 8.6%, as well as increasing Nusselt number, Overall heat transfer coefficient and effectiveness of heat exchanger with average 26%,15% and 13% respectively. The results clear that, for 225°C exhaust air and velocity 27 m/s, the application of double pipe with helical fins by preheat heavy fuel oil could reduce the viscosity and reduce electric power required and save 1.69 MW annually for one factory.

Published: January 2024

The study of low Reynolds number flows has triggered the interest of many researchers. This concern is attributed to the presence of various vortex structures that significantly affect aerodynamic performance. The study of such phenomena offers an opportunity to better understand and predict the behavior of fluid flows in three dimensions, leading to improved design strategies for aerodynamic systems. This study intends to examine the performance of different NACA 0015 airfoil configurations namely, baseline, serration, comb, comb-serration and poro-serrated, emphasizing on their influence on aerodynamic characteristics and flow structure. Experimental work is performed to provide valuable insights into the behavior of the flow field and the underlying physical phenomena. The current study has shown that the mean streamwise velocity of the serrated, combed, and comb-serrated configurations exhibit more stable flow patterns compared to the baseline airfoil. These patterns suggest a promising approach for delaying flow separation. In contrast, the poro-serrated model exhibited a more disordered flow pattern. Remarkably, when subjected to a 10-degree angle of attack, all the modified trailing-edge designs showcased minimal separation zones compared to the baseline configuration. At the same angle, the baseline's shear layer disintegrates, while the poro-serrated model displays increasing disturbance and separation. Conversely, the comb-serrated and serration models exhibit a smaller increase in unsteadiness. Furthermore, the study indicated that Musou black paint exhibits a higher rate of light absorption compared to flat black paint, but it demonstrates higher reflection levels on a poro-serrated surface. Collectively, the outcomes of this investigation hold significant implications for enhancing aerodynamic system designs.

The adsorption cooling system is an environmentally friendly system because of non-CFCs (chlorofluorocarbons) and non-HCFCs (hydrochlorofluorocarbons). The simulation developed is an adsorption system that can operate with a low temperature waste heat source so that this adsorption system can be applied to building cooling systems. The purpose of this research is to obtain the most effective and efficient cycle of three bed silica gel-water adsorption system with a low temperature heat source so that it has the potential for building applications. The method developed is by simulating various design combinations of three bed adsorption systems and simulating 6 (six) cycle types. Furthermore, those designs of silica gel-water based two different types of three-bed adsorption chiller has been analyzed statically. The performance of the chillers was investigated in terms of coefficient of performance (COP) and specific cooling effect (SCE) for heat source temperature between 60oC and 90oC. The result first shows that the performance data of the proposed chillers (Cycle E and Cycle F) were compared with those of other four different types of three-bed adsorption chiller with the same operating conditions. It was observed that the proposed chillers provided a higher SCE compared with other four assorted chillers. Second result show that The Cycle B obtained the higher COP comparing with the other cycles designed in this study. Thus, this system has a good potential to be developed for building cooling systems by utilizing heat waste.

The Gamma-Ray Origin of RX J0852.0-4622 Quantifying the Hadronic and Leptonic Components: Further Evidence for the Cosmic-Ray Acceleration in Young Shell-type SNRs

Published: January 2024

Fukui et al. quantified the hadronic and leptonic gamma-rays in the young TeV gamma-ray shell-type supernova remnant (SNR) RX J1713.7-3946 (RX J1713), and demonstrated that gamma rays are a combination of hadronic and leptonic gamma-ray components with a ratio of ∼6: 4 in gamma-ray counts N
g. This discovery, which adopted a new methodology of multi-linear gamma-ray decomposition, was the first quantification of the two gamma-ray components. In the present work, we applied the same methodology to another TeV gamma-ray shell-type SNR RX J0852.0-4622 (RXJ0852) in 3D space characterized by (the interstellar proton column density N
p)-(the nonthermal X-ray count N
x)-[N
g], and quantified the hadronic and leptonic gamma-ray components as having a ratio of ∼5:5 in N
g. The present work adopted the fitting of two/three flat planes in 3D space instead of a single flat plane, which allowed suppression of the fitting errors. This quantification indicates that hadronic and leptonic gamma-rays are of the same order of magnitude in these two core-collapse SNRs, verifying the significant hadronic gamma-ray components. We argue that the target interstellar protons, in particular their spatial distribution, are essential in any attempts to identify the type of particles responsible for gamma-ray emission. The present results confirm that cosmic-ray (CR) energy ≲100 TeV is compatible with a scheme in which SNRs are the dominant source of these Galactic CRs.
Low-energy Explosions in a Gravitational Field: Implications for Sub-energetic Supernovae and Fast X-Ray Transients
Authors: Paradiso Daniel A. , Coughlin Eric R. , Zrake Jonathan , Pasham Dheeraj R.
Published: January 2024

Observations and theory suggest that core-collapse supernovae can span a range of explosion energies, and when sub-energetic the shockwave initiating the explosion can decelerate to speeds comparable to the escape speed of the progenitor. In these cases, gravity will complicate the explosion hydrodynamics and conceivably cause the shock to stall at large radii within the progenitor star. To understand these unique properties of weak explosions, we develop a perturbative approach for modeling the propagation of an initially strong shock into a time-steady, infalling medium in the gravitational field of a compact object. This method writes the shock position and the post-shock velocity, density, and pressure as series solutions in the (time-dependent) ratio of the freefall speed to the shock speed, and predicts that the shock stalls within the progenitor if the explosion energy is below a critical value. We show that our model agrees very well with hydrodynamic simulations, and accurately predicts (for example) the time-dependent shock position and velocity and the radius at which the shock stalls. Our results have implications for black hole formation and the newly detected class of fast X-ray transients (FXTs). In particular, we propose that a “phantom shock breakout”—where the outer edge of the star falls through a stalled shock—can yield a burst of X-rays without a subsequent optical/UV signature, similar to FXTs. This model predicts the rise time of the X-ray burst, t
d, and the mean photon energy, kT, are anticorrelated, approximately as

Transverse MHD Waves as Signatures of Braiding-induced Magnetic Reconnection in Coronal Loops
Authors: Sukarmadji A. Ramada C. , Antolin Patrick
Published: January 2024

A major coronal heating theory based on magnetic reconnection relies on the existence of braided magnetic field structures in the corona. In this small-angle reconnection scenario, numerical simulations indicate that the reconnected magnetic field lines are driven sideways by magnetic tension and can overshoot from their new rest position, thereby leading to low-amplitude transverse MHD waves. This provides an efficient mechanism for transverse MHD wave generation, and the direct causality also constitutes substantial evidence of reconnection from braiding. However, this wave-generation mechanism has never been directly observed. Recently, the telltale signature of small-angle reconnection in a sheared coronal structure has been identified through nanojets, which are small, short-lived, and fast jetlike bursts in the nanoflare range transverse to the guide field. We present for the first time Interface Region Imaging Spectrograph and Solar Dynamics Observatory observations of transverse MHD waves in a coronal loop that directly result from braiding-induced reconnection. The reconnection is identified by the presence of nanojets at the loop apex that release nanoflare-range energy. We find that the oscillations have an energy flux on the order of 106–108 erg cm−2 s−1, which is within the budget to power active region loops. The estimated kinetic and thermal energy from the nanojets is also sufficient to power the transverse waves and sustain the observed heating at the loop apex. This discovery provides major support to (a) existing theories that transverse MHD waves can be a signature of reconnection, (b) the existence of braiding in coronal structures, and (c) the coronal reconnection scenario identified by nanojets.
Lunar Mare Lava Flow Dynamics and Emplacement: Predictions of Non-Newtonian Flow Dynamics, Syn- and Post-emplacement Cooling and Volatile Release Patterns, and Vertical and Lateral Flow Structure Development
Authors: Wilson Lionel , Head James W.
Published: January 2024

We apply basic principles of magma ascent from deep source regions and its eruption into a low-gravity vacuum environment to develop a theoretical treatment of the fluid dynamics and thermodynamics of mare basalt lava flow emplacement and evolution on the Moon. The vacuum conditions influenced the release of volatiles in magma passing through lava fountains, thus controlling the syn- and post-emplacement vesicularity of the resulting deposits. To explain observed lengths and volumes of Mare Imbrium–type flows, high (106–105 m3 s−1) initial magma eruption rates were needed. Combined with low lunar magma viscosity, these caused flows to be initially turbulent. Resulting high radiative heat loss and consequent high crystallization rates caused rapid non-Newtonian rheological evolution and suppression of turbulence at tens of kilometers from vents. Slower cooling rates in the subsequent laminar parts of flows imply distinctive crystal growth rate histories. In a four-phase sequence, (i) initial transient dike-tip gas release followed by (ii) Hawaiian fire fountain activity with efficient volatile loss (iii) transitioned to (iv) Strombolian explosions in a lava lake. Late-stage lava now able to retain volatiles intruded and inflated existing flow deposits after flow front advance ceased. Volatiles forced out of solution by second boiling as lava cooled caused additional inflation. Low gravity and lack of atmospheric pressure commonly produced very vesicular lava. Escape of such lava through cracks in flow crusts is a possible source of ring-moat dome structures; collapse of such lava may explain irregular mare patches.

We have monitored the Didymos–Dimorphos binary system in imaging polarimetric mode before and after the impact from the Double Asteroid Redirection Test mission. A previous spectropolarimetric study showed that the impact caused a dramatic drop in polarization. Our longer-term monitoring shows that the polarization of the post-impact system remains lower than the pre-impact system even months after the impact, suggesting that some fresh ejecta material remains in the system at the time of our observations, either in orbit or settled on the surface. The slope of the post-impact polarimetric curve is shallower than that of the pre-impact system, implying an increase in albedo of the system. This suggests that the ejected material is composed of smaller and possibly brighter particles than those present on the pre-impact surface of the asteroid. Our polarimetric maps show that the dust cloud ejected immediately after the impact polarizes light in a spatially uniform manner (and at a lower level than pre-impact). Later maps exhibit a gradient in polarization between the photocentre (which probes the asteroid surface) and the surrounding cloud and tail. The polarization occasionally shows some small-scale variations, the source of which is not yet clear. The polarimetric phase curve of Didymos–Dimorphos resembles that of the S-type asteroid class.
Towards a set of metrics for hybrid (quantum/classical) systems maintainability
Authors: Muñoz Ana Díaz , Monje Moisés Rodríguez , Velthuis Mario Gerardo Piattini
Published: January 2024

Given the rapid evolution that has taken place in recent years in the software industry, and along with it the emergence of quantum software, there is a need to design an environment for measuring quality metrics for hybrid, classic-quantum software. 

In order to measure and evaluate the quality of classic software, there are models and standards, among which ISO/IEC 25000 stands out, which proposes a set of quality characteristics such as maintainability. However, there is currently no consensus for the measurement and evaluation of quantum software quality. 

In this paper we propose a series of adaptations to “classic” metrics, as well as a set of new measurements for hybrid maintainability. Finally, a first prototype of a measurement tool developed as a SonarQube plugin, capable of measuring these metrics in quantum developments, is also presented.

Hedysarum qilianshanensesp. nov. (Fabaceae, Hedysareae) is described and illustrated from the Qilianshan Mountains in Gansu, China. This new species is similar to H. przewalskii, but can be distinguished by its corolla being light purple to purple, standard 15–19 mm long, wings 14–16 mm long, keels 16–19 mm long, and the ovary and legume being glabrous. The new species can be easily distinguished from H. neglectum Ledeb. by its bract being shorter than the pedicel, and the ovary and legume being glabrous. Phylogenetic tree based on the nuclear ITS and ETS sequences shows that H. qilianshanense is sister to H. przewalskii, while the tree based on the plastid psbA-trnH, trnC-petN, trnL-F, trnS-G and petN-psbM sequences shows H. qilianshanense as sister to a clade consisting of H. hedysaroides, H. inundatum, H. americanum and H. neglectum. The new species is a diploid with the chromosome number 2n = 14. Based on morphological, phylogenetic and karyotypic evidence, the new species may originate from an ancient homoploid hybrid speciation event.

And the results showed that HR respondent 1 to 5 said LMs play an important role and are needed to carry out HR activities.Originality/value: The analysis of the case, highlights the benefits of the novel idea of line managers and human resource practitioners and contributes to the need for greater clarity and knowledge of the barriers in the involvement of LMs in HR activities.  Social implications: This study has shown LMs and HR practitioners have their different reserves about working together but the issue presently is, none of them is dispensable so they have to work together. It is necessary for HR practitioners to consult LMs when formulating policies and procedures to ensure balance between business needs and standard policies, and procedures.

L’importance de la fonction écologique de la langue quechua
Authors: Jiménez Marina Arratia
Published: January 2024

L'importance de la fonction écologique de la langue quechua1 repose sur le fait que cette langue codifie un système de connaissances ethnoécologiques et une vision biocentrique du monde. Cette façon d'interpréter le monde implique à son tour une façon d'agir dans ce monde. Cet article s'appuie sur les résultats d'une recherche menée dans une communauté paysanne andine de langue quechua, située dans la zone géographique où se trouve la plus grande biodiversité de tubercules andins en Bolivie. Basée sur une exploration des connaissances sur la biodiversité de la pomme de terre, l'étude révèle le lien entre le territoire, la culture et la langue. Ce lien ouvre une nouvelle perspective pour la revitalisation des langues indigènes, en se concentrant non seulement sur la langue, mais aussi sur le renforcement des communautés de locuteurs et sur la protection et la restauration environnementale de leurs territoires et de leurs systèmes de production traditionnels, territoires qui sont également considérés comme des espaces vivants pour les langues.
Le bi-plurilinguisme : quand la représentation fait émerger les langues maternelles
Authors: Benazzouz Abdelnour
Published: January 2024

Ce travail, en sociolinguistique générale, s’intéresse à faire affleurer en discours des représentations chez un locuteur algérien ordinaire, sur sa pratique bi- ou plurilingue à travers l’exercice de l’interview sociolinguistique. Cette dernière pointe des pratiques bilingues en contexte suivant des niveaux de fonctionnements qui appellent des domaines d’usage de l’alternance, lequel véhicule une représentation sur les langues et non pas sur le bilinguisme en tant que pratique à part entière.
Actitudes lingüísticas en tres comunidades hispano-lusas de fronteira: Miranda do Douro, Val do Ellas e Olivença
Authors: Costas Xosé-Henrique
Published: January 2024

[résumé en galicien] Na fronteira entre España e Portugal hai unha serie de enclaves que resisten a asimilación lingüística e cultural baixo a presión / opresión da ideoloxía lingüística estatal correspondente, portuguesa ou española.Trátase de Miranda do Douro (Tras-os-Montes, Portugal) onde hai aínda unha comunidade de 3.500 persoas falantes dun tipo de asturleonés chamado mirandés; do Val do río Ellas, ou de Xálima ( noroeste de Cáceres, España ), onde hai unha comunidade de 4.500 falantes dunhas variedades derivades do galego medieval; e de Olivença ( Badallouce, España ) onde aínda 3.000 persoas mantenen viva a lingua portuguesa.Entre marzo de 2020 e novembro de 2022 realizamos máis de 550 enquisas de usos e actitudes lingüísticas dos falantes destas variedades. Os puntos de partida históricos, culturais, sociolingüísticos e lexislativos eran diferentes, pero os resultados son moi semellantes en dúas (Miranda e Olivença) e moi especial na outra (Val do Ellas). Trataremos de facer unha aproximación sociolingüístca ás actitudes e as ideoloxías lingüísticas destas variedades minorizadas.
Cançó en llengua minoritzada i revitalització
Authors: Fraj Eric
Published: January 2024

Everyone knows that singing is a fun and enjoyable way to learn a language, and an effective way. We also know that this effectiveness can, from pedagogy to politics, affect more than one field. The historical importance of artistic movements such as "La nova cançó" in Catalonia or "La nòva cançon occitana" in Occitania, and in the rest of France, is well established. Nevertheless, if the benefits of the song are obvious in terms of the revitalization of a minority language, we must question the limits of such a practice. Indeed, we should not fall into the illusion that the work of art can do everything. Despite its undeniable advances, especially on the symbolic level, the song is insufficient in terms of the effective revitalization of a minority language. Our purpose will be to say why the song is both an indispensable and limited means, and to show what broader process it should integrate so that the resocialization of the minority language is real.
Est-il préférable d’apprendre les langues minoritaires à l’âge adulte ?L’exemple du breton
Authors: Gildas Grimault
Published: January 2024

La politique éducative est l’un des outils privilégiés des politiques de revitalisation des langues minoritaires. Or, elle est envisagée d’abord par le développement d’un apprentissage à destination des enfants. L’enseignement aux adultes passe souvent au second plan que ce soit en termes de revendications par la société civile organisée ou que ce soit en termes de politiques éducatives. A contre-courant, le linguiste gallois Jones affirmait que « dans le processus de restauration de la langue, le facteur déterminant est et doit être l’enseignement aux adultes » (1993). Nous nous proposons d’interroger cette assertion en menant une étude comparative entre l’enseignement à destination des enfants et celui à destination des adultes en Bretagne. Après avoir exposé les arguments avancés par Jones, nous les mettrons en tension avec la situation sociolinguistique du breton. Quelles différences entre l’apprentissage des adultes et des adolescents ? Quel désir anime chacun des groupes d’âges ? De quelle manière les adultes et les adolescents envisagent-ils leurs socialisations langagières une fois l’apprentissage terminé ?
À propos de la loi pour contrôler l'immigration, améliorer l'intégration, entretien avec Serge Slama, professeur à l’Université Grenoble Alpes
Authors: Slama Serge
Published: January 2024

Le présent entretien poursuit la série consacrée, depuis le début de l’année, à la loi sur l’immigration adoptée le 19 décembre 2023. À quelques jours de la décision du Conseil constitutionnel, un focus est proposé grâce à Serge Slama sur les nombreuses contributions extérieures thématiques destinées à alerter et à mobiliser contre ce texte.Entre Noël et Nouvel An 2023, peu après avoir été saisi par le Président de la République, la présidente de l’Assemblée, 60 députés et 60 sénateurs, le Conseil constitutionnel a été destinataire, en application de l’article 13 de son règlement de procédure, d’une douzaine de contributions extérieures thématiques élaborées par des universitaires spécialisés et des représentants d’associations ou de syndicats. Cette démarche visait à fournir, suffisamment en amont, au Conseil les arguments juridiques et contextuels lui permettant, s’il le veut, de censurer en tout, ou en partie, ce texte – même s’il ne faut se faire aucune illusion sur les vertus protectrices des étrangers du contrôle de constitutionnalité des lois. Il s’agit aussi d’ouvrir un front juridique dans les mobilisations jusque-là très peu visibles contre cette loi « Darmanin-Ciotti-Le Pen » adoptée dans des conditions rocambolesques. La décision n°2023-863 DC que rendra le Conseil constitutionnel le 25 janvier 2024 s’inscrit néanmoins dans un contexte inédit où le Président de la République, l’ancienne Première ministre et le ministre de l’Intérieur ont reconnu eux-mêmes que le texte adopté est entaché d’inconstitutionnalités.
“Nous avons suivi le doigt de Stanislas”. Entretien avec Charles Tordjman autour du Festival Passages
Authors: Tordjman Charles , Hoffert Yannick , Kempf Lucie
Published: January 2024

Dans cet entretien, le metteur en scène Charles Tordjman, qui dirigea le Théâtre de la Manufacture – Centre dramatique national de Nancy-Lorraine, de 1992 à 2009, revient sur la création et le développement du Festival Passages, consacré aux théâtres de l’est de l’Europe. Ce festival a été créé en 1996, à une époque charnière où, à la suite de la chute du mur de Berlin, les échanges culturels entre Europe occidentale, centrale et orientale pouvaient reprendre sur des bases nouvelles. Si les débuts du festival furent matériellement modestes, la manifestation a rapidement pris une grande ampleur, à la fois localement dans la vie culturelle nancéienne et lorraine, nationalement et internationalement. Passages est devenu une plateforme à partir de laquelle des artistes novateurs et des traditions très anciennes ont pu acquérir une notoriété en Occident. Des carrières ont pu se développer et des échanges culturels inédits ont pu s’inventer. Le festival a également suscité l’émergence de pratiques innovantes en matière de relations avec les publics, notamment pour ce qui est de la conception des espaces et de l’accessibilité des spectacles (traductions et surtitrages).
