Comparative analysis of as-delivered heat-resistant bearing steels
Authors: Pugacheva T.M.
Published: October 2023

A comparative analysis of the regulatory document requirements and the actual metallurgical quality characteristic values of domestic (8Kh4V9F2-Sh, 8Kh5M3VFB-ID) and foreign (M50 VIM-VAR) as-delivered heat-resistant bearing steels is carried out. The chemical composition, non-metallic inclusions, carbide heterogeneity, carbide morphology and hardness of hot-rolled bars of different diameters are studied. Additionally, the heat resistance is determined. It is established that the best quality (narrow component ranges, less non-metallic inclusions contamination, carbide heterogeneity and hardness) has M50 VIM-VAR steel, the worst quality is 8Kh4V9F2-Sh steel, which meets the most stringent requirements of regulatory documentation for M50 VIM-VAR steel. In bars with a diameter of up to 22 mm, the quality of all steels according to the studied characteristics does not noticeably differ. 8Kh5M3VFB-ID steel has the widest range of carbon and chromium content, the highest hardness, aluminum nitrides and eutectic carbides of the "honeycomb" type are observed. 8Kh4V9F2-Sh steel has the most heat-resistant, which allows its use at higher operating temperatures. The obtained data can be used when choosing a steel grade for bearings of a specific range.

Service learning on disaster readiness and risk reduction information: perspectives from students and community members
Authors: Orillo Jhoanne , Prudente Maricar
Published: October 2023

The study explored the conduct of a service learning (SL) activity by senior high school students (N=110) in disseminating information about Disaster Readiness and Risk Reduction (DRRR) to community participants (N=139). Senior high school students from a public sector senior high school in the Philippines conducted a community service learning activity. Before conducting the service learning activity, students determined the familiar disasters that the community participants commonly experienced and then developed the DRRR brochure. Students compiled their DRRR learning into a brochure and used it to discuss disaster mitigation with the community. Researchers used standardised tests and survey forms to determine the participants' pre and post-knowledge, skills and attitudes toward disasters. Quantitative results showed that both the student and community participants perceived that the service learning activity had allowed them to gain more knowledge on disaster mitigation with an overall Disaster Related Knowledge Questionnaire (DRKQ) of p<0.05. Likewise, Civic Action and Skills Questionnaire (CASQ) revealed that the activity helped the students to improve their communication and social skills and the community participants' leadership skills at p<0.05. The qualitative data showed that both the students and the community participants better understood the DRRR concepts and perceived that the service learning activity had benefited and taught them disaster mitigation.

Authors: Střída Miroslav , Kašpar Václav
Published: October 2023

The annual review of national and international works on Czechoslovakia has been published for ten years in the new identical arrangement. It has been published regulary in the Journal of the Czechoslovak Geographical Society No. 2, since 1961. There we present yearly a wide choice of original and derived books, articles, maps and other geographical and regional works on Czechoslovakia, published in the last year, exceptionally the year before last. The general theoretical and methodical studies and maps published by Czech and Slovak authors only contain the bibliographical system of General Geography. The regional system Czechoslovakia is divided into several sections and parts. Works covering the whole Czechoslovak or Slovak territory are summed up as Generalities. The section Physical Geography is divided into the part "Geomorphology", the karst investigation included, and into the part "Climatology, Hydrology, Biogeography, Pedology". In the same way in the section of "Human Geography" is distinguished the part "Population and Settlement" and "Economic Geography". The books, articles and maps, of regional character, the guides and maps get into the section "Regional works". The Czechoslovak geographical bibliography has in recent years been the collective job of the geographers of the Institutes of Geography in Czechoslovak and Slovak Academy of Science under the collaboration of some Universities and the Central Office for Geodesy and Cartography. The selection has been revised by the editorial board of our Journal. Concerning further bibliographical references to Czechoslovak geography, we should like to mention a simple review of geographical works published in the Institute of Geography of the Czechoslovak Academy of Sciences for the period 1961-1965.

Authors: Phillip George J. , Hussey Benthan H.
Published: October 2023

A to Z of Industrial Relations in the Caribbean Workplace is a revision and expansion of the earlier successful publication of A-Z of Industrial Relations Practices at the Workplace by George Phillip. It comes against the background of a new era in Caribbean economic history and experience. Designed for both managers and workers in this new order, the A to Z offers useful strategies for understanding and handling absenteeism, strikes, fighting on the job, productivity and wage compensation. It emphasizes that the key to productive and positive relationship between managers and workers is the establishment of mutual trust in the workplace. This new project also recognizes and highlights the modern trend in disputes resolution, the preference for conciliation and alternative disputes resolution methods over litigation. The Caribbean's social and economic history has been fraught with conflict and confrontation, and as such, the region faces a particularly difficult challenge to use a more cooperative approach to resolving industrial relations problems. Trinidad and Tobago have been highlighted for purposes of comparison and contrast. This feature has also been complemented with a selection of industrial relations cases from Barbados, Jamaica, and Trinidad and Tobago, suitably summarized and analysed. A to Z is an excellent practitioner's guide as well as reference and guide for academics.

La miocardiopatía hipertrófica es una enfermedad genética con una alta heterogeneidad en diferentes aspectos. Una de sus formas poco conocidas es la miocardiopatía hipertrófica apical la cual se caracteriza por un compromiso, casi exclusivo, del ápice ventricular izquierdo, y se distingue por la morfología de as de picas en la ventriculografía. El ECG es un método diagnóstico para dicha patología pero diferentes métodos diagnósticos no invasivos como la resonancia magnética cardíaca nos permite confirmar su diagnóstico debido  a su mayor resolución y apreciación de la morfología cardiaca. Realizamos una búsqueda bibliográfica de artículos en inglés y español con distintos descriptores lo cual dio como resultado el hallazgo de diferentes reportes de casos en los que se destacan el papel de la resonancia magnética cardiaca como método de diagnóstico de gran utilidad en la miocardiopatía hipertrófica apical. Por ello, los métodos de imagen como la resonancia magnética, desempeñan un papel crucial en la identificación de las características morfológicas y en la evaluación de las complicaciones asociadas a esta patología

OVERARCHING OVERTONES: ORACLES ON CAREER CHRONICLES OF WOMEN IN INDIAN HOTEL INDUSTRY
Authors: Eugene J.
Published: October 2023

The hospitality sector has been witnessing tremendous changes of late in terms of gender diversity with the increased participatory role of women at all levels of the workforce. The global food and beverage, and lodging industries have been proactively getting women on board down the years, recognising their important role in enhancing visitor satisfaction translating into repeat visits. This trend is however more widespread and popular in developed countries. India’s unique cultural values, social traditions, conventional customs, gender stereotyping, conservative attitudes and religious beliefs have all been challenging age-old obstacles that have largely hindered the greater employment and integration of women in the hospitality sector’s labour market. It is only from the 1960s that the women workforce in the Indian precincts saw limited presence and then slowly grew in numbers. This analytical research paper actively seeks to explore and highlight the trajectory of women employees in the hotel industry. Accurate and objective data for this investigative analysis is obtained from several leading five-star hotels in Chennai. Insights into the hospitality sector are obtained through interaction with a number of women holding managerial positions. The gathered data is decoded, and variables that help it are extracted. This research study on the work trends, changing industry dynamics and administrative challenges encountered by women in the hospitality sector can help establish gender parity by promoting a greater number of women to join the ranks and raise the profile of women in the hotel industry.

Authors: Trivedi Vinay , Patel Vipul
Published: October 2023

The rural education landscape in Gujarat, India, has long been burdened by various challenges that hinder the empowerment and development of its youth. In response, a new policy has been introduced to transform the educational system and provide greater opportunities for rural youth. This abstract provides an overview of the policy's key elements and objectives.
The policy recognizes the need for inclusive and equitable access to quality education for all rural students. It addresses disparities in infrastructure, resources, and teaching methodologies, aiming to bridge the urban-rural education divide. The primary goal is to empower youth by equipping them with the knowledge, skills, and competencies needed to thrive in a rapidly evolving global landscape.
To achieve this, the policy focuses on enhancing the quality of education through investments in teacher training programs, curriculum development, and pedagogical reforms. It promotes the use of technology-enabled learning tools and innovative teaching methods that encourage critical thinking, problem-solving, and creativity.
The policy also emphasizes the importance of vocational education and skill development. It aims to strengthen vocational training programs, establish industry-academia linkages, and encourage entrepreneurship among students. This approach equips youth with practical skills aligned with the evolving job market, fostering employability and economic self-sufficiency.
Moreover, the policy advocates for comprehensive student support systems, including career counselling, mentorship programs, and scholarships. Special attention is given to marginalized and disadvantaged groups, aiming to address social and gender disparities within the rural education system.
Effective collaboration between government agencies, educational institutions, civil society organizations, and the community is crucial for the policy's success. Robust monitoring and evaluation mechanisms are proposed to assess progress, identify gaps, and make necessary adjustments for long-term impact.
By transforming Gujarat's rural education landscape, this policy seeks to empower youth with the knowledge, skills, and confidence needed to overcome socio-economic challenges and contribute meaningfully to society. It aspires to create a future generation of capable, self-reliant individuals who actively participate in the growth and development of their communities and the nation as a whole.
ROLE OF SENIOR CITIZENS IN SCHOOLS IN THE LIGHT OF NATIONAL EDUCATION POLICY (NEP) 2020
Authors: Mishra Akhilesh , Pandey Sunil Kumar
Published: October 2023

India is a country where there is a large diversity in terms of opportunities and accessibility to education. Various efforts are being made by Govt. and NGOs to minimise this gap. National Education Policy (NEP) 2020 suggests involving the community in the schools to fill the gap. Senior citizens being an important part of the community would be highly beneficial for the schools as they have a vast range of life experiences. We must understand that senior citizens are not liabilities but one of the most important assets for the community provided if they get opportunities. School may be the best platform to give such opportunities. This paper explores the potential contributions of senior citizens in schools based on NEP 2020 and identified various activities like developing values in children, Promoting Foundational Literacy and Numeracy, Promoting Indian Knowledge system and Indian local languages, preparing and distributing mid-day meal in schools, arranging human and financial resources for schools, taking care of children’s emotional health, early identification of the needs of the children, ensuring participation of female and transgender children in education, etc in which they can be engaged into the schools. It also suggests the process by which the schools can render their services.
RAW MATERIALS PRICE VOLATILITY AND ECONOMIC IMPACTS ON THE JAMNAGAR BRASS PARTS INDUSTRY: A STUDY ON MICRO AND SMALL-SCALE UNITS
Authors: Nakum Dharmendra M.
Published: October 2023

Most of the production work is carried out by micro and small-scale units in the Jamnagar Brass Parts industry. Brass scrap is most often used in this industry. Brass scrap prices are based on brass metal prices, and Brass is composed of a mixture of copper, zinc, and lead metals, in addition, copper holds the highest position among other related metals. Therefore, the highest percentage of copper can be found in comparison to other metals. When it comes to brass scrap, prices mostly depend on copper prices. Copper is considered a globle metal today, with developed countries dominating both its production and consumption. In this regard, over the past few years, copper prices have experienced significant instability. Consequently, brass prices also exhibit instability. In this research paper focuses on the Jamnagar Brass Parts industry and examines the economic impacts and challenges arising from the volatility in prices of raw materials, such as brass scrap, on both foundry units and manufacturing units. Furthermore, these small-scale units find themselves in an uncertain position as a result of the volatile fluctuations in raw material prices. Consequently, these units react or respond to the price fluctuations of raw materials like brass scrap. This paper also tries to address this issue.

La reflexión moral cada vez es más unánime al considerar que la relación del hombre con la naturaleza y la intervención técnica sobre ella, puede y debe ser objeto de valoraciones éticas. En relación con la naturaleza no todo vale. Existen buenas y malas prácticas de intervención y aprovechamiento de los recursos naturales. El enorme poder del que dispone el hombre a través de la técnica, plantea el problema de los límites. Ahora bien, quién impone tales límites. El mutismo de la naturaleza puede interpretarse como una pasividad de cosa ahí, sin otro valor que su disponibilidad como objeto de explotación y fuente inagotable de recursos. Sin embargo, los desajustes que se generan en la naturaleza como consecuencia de la acción humana, muestran su condición de fragilidad y vulnerabilidad. Los medios tecnológicos de intervención son tan potentes y con efectos tan dramáticos que los fines buscados no compensan con el resultado catastrófico y a veces irreversible de los daños causados. Las posibilidades de intervención en la naturaleza parecen no tener otro límite que el que permite el desarrollo tecnológico. Contener los cauces de ríos, atrapar las corrientes de aire, perforar las profundidades de la tierra y del mar, transformar las materias primas, experimentar con la genética y modificar animales y plantas, llenar la órbita geoestacionaria de artefactos y residuos, invadir y arrasar las selvas y parques naturales, romper los átomos y estallar el mundo, envenenar ejércitos, desterrar aves y animales de sus hábitats… etc., todo esto y mucho más ya es posible hacerlo. Por primera vez en la historia de la humanidad la naturaleza parece inerme ante el despliegue del poderío humano.
MBSE-LITE: A FRAMEWORK FOR ADOPTING MODEL-BASED SYSTEMS ENGINEERING IN SMALL AND MEDIUM-SIZED ENTERPRISES IN SOUTH AFRICA
Authors: Nanfuka Justine Geraldine , Oosthuizen Rudolph
Published: October 2023

Purpose – This research aims to characterise the landscape and factors for successfully implementing Systems Engineering (SE) and Model-Based Systems Engineering (MBSE) in the enterprise.
Research methodology – The study investigated the factors across different industries that affect the success of MBSE in an enterprise using a survey questionnaire. The research focussed on the uptake and implementation of MBSE in Small and Medium-sized enterprises (SMEs) in South Africa. More than 100 industry professionals participated in the study.
Findings – The survey revealed that SMEs have trouble adopting and implementing MBSE because they are unaware of its applicability and lack economic justification and support from upper management. Quantitative data analysis assessed how factors such as MBSE training, existing SE processes in the enterprise, and how long the company has been using MBSE contribute to the success of MBSE adoption in SMEs.
Research limitations – The population size limited the study reached and the time available to conduct the research. However, it does not reduce the results’ strength and validity.
Practical implications – The analysis showed that training and an existing SE structure are highly significant, while the age of MBSE in the enterprise does not correlate with its success. Therefore, these results proposed an adoption framework for SMEs in South Africa to aid MBSE adoption by incorporating training and a clear uptake and implementation process.
Originality/Value – This research builds on the growing body of literature about implementing MBSE and enterprises. The conclusions provide valuable insights and guidelines for implementing MBSE in SMEs.

FORGING CONNECTIONS: THE SOCIAL DYNAMICS OF “DEATH STRANDING” AS A PARADIGM SHIFT IN GAMING
Authors: Bostan Barbaros , Şengün Sercan
Published: October 2023

This paper explores the video game Death Stranding as a shift in digital interactive media, emphasizing altruism, collaboration, and social connection in its gameplay. The close reading of the game focuses on features that diverge from traditional norms, pivoting towards a more empathetic, community-driven model and identifies five domains of analysis: narrative infrastructure; game mechanics; player-to-player interactions; player-to-NPC interactions; and player interactions as a social agent. The findings are discussed with the possibility of defining a new genre, named by the game’s creator as a “strand game” (Kojima, 2019a, 2019b). The analysis reveals Death Stranding’s ability to create a deeply immersive sense of unity among players, demonstrating the game’s potential as a model for future video games that prioritize positive social interactions and mutual support.
Chandra Observation of NGC 1559: Eight Ultraluminous X-Ray Sources Including a Compact Binary Candidate

Published: October 2023

Despite the 30 yr history of ultraluminous X-ray sources (ULXs) studies, issues such as the majority of their physical natures (i.e., neutron stars, stellar-mass black holes, or intermediate black holes) as well as the accretion mechanisms are still under debate. Expanding the ULX sample size in the literature is clearly a way to help. To this end, we investigated the X-ray source population, ULXs in particular, in the barred spiral galaxy NGC 1559 using a Chandra observation made in 2016. In this 45 ks exposure, 33 X-ray point sources were detected within the 2.′7 isophotal radius of the galaxy. Among them, eight ULXs were identified with the criterion of the X-ray luminosity L
x > 1039 erg s−1 (0.3–7 keV). Both X-ray light curves and spectra of all the sources were examined. Except for some low-count spectra that only provide ambiguous spectral fitting results, all the X-ray sources were basically spectrally hard and therefore likely have nonthermal origins. While no strong X-ray variability was present in most of the sources owing to the relatively short exposure of the observation, we found an intriguing ULX, named X-24, exhibiting a periodicity of ∼7500 s with a detection significance of 2.7σ. We speculate that it is the orbital period of the system. Roche-lobe overflow and Roche limit are consistent with the speculation. Thus, we suggest that X-24 may be one of the rare compact binary ULXs, and hence, a good candidate as a stellar-mass black hole.

The tip of the red giant branch provides a luminous standard candle for calibrating distance ladders that reach Type Ia supernova (SN Ia) hosts. However, recent work reveals that tip measurements vary at the ∼0.1 mag level for different stellar populations and locations within a host, which may lead to inconsistencies along the distance ladder. We pursue a calibration of the tip using 11 Hubble Space Telescope fields around the maser host, NGC 4258, that is consistent with SN Ia hosts by standardizing tip measurements via their contrast ratios. We find F814W-band tips that exhibit a full 0.3 mag range and 0.1 mag dispersion. We do not find any correlation between H i column density and the apparent tip to 0.04 ± 0.03 mag/cm−2. We search for a tip–contrast relation (TCR) and measure the TCR within the fields of NGC 4258 of −0.015 ± 0.008 mag/R, where R is the contrast ratio. This value is consistent with the TCR originally discovered in the GHOSTS sample of −0.023 ± 0.005 mag/R. Combining these measurements, we find a global TCR of −0.021 ± 0.004 mag/R and a calibration of

We also use stellar models to simulate single age and metallicity stellar populations with [Fe/H] from −2.0 to −0.7 and ages from 3 to 12 Gyr and reconstruct the global TCR found here to a factor of ∼2. This work is combined in a companion analysis with tip measurements of nearby SN Ia hosts to measure H

Outlier Detection in the DESI Bright Galaxy Survey
Authors: Liang Yan , Melchior Peter , Hahn ChangHoon , Shen Jeff , Goulding Andy , Ward Charlotte
Published: October 2023

We present an unsupervised search for outliers in the Bright Galaxy Survey (BGS) data set from the DESI Early Data Release. This analysis utilizes an autoencoder to compress galaxy spectra into a compact, redshift-invariant latent space, and a normalizing flow to identify low-probability objects. The most prominent outliers show distinctive spectral features, such as irregular or double-peaked emission lines or originate from galaxy mergers, blended sources, and rare quasar types, including one previously unknown broad absorption line system. A significant portion of the BGS outliers are stars spectroscopically misclassified as galaxies. By building our own star model trained on spectra from the DESI Milky Way Survey, we have determined that the misclassification likely stems from the principle component analysis of stars in the DESI pipeline. To aid follow-up studies, we make the full probability catalog of all BGS objects and our pretrained models publicly available.

Published: October 2023

During the 2022 R/V cruises in the Yellow Sea, four goby specimens (51.2‒63.5 mm) were captured by using an Agassiz trawl at a water depth of about 70 meters. These specimens were identified as Suruga fundicola, mainly by the morphometric characters. Their identification was further confirmed by a molecular phylogenetic analysis based on 12S and COI mtDNA genes. Considering that the four specimens were in good condition and that the original description is brief, a detailed description of the specimens is given. Moreover, the present study presents a preliminary analysis of its phylogenetic position within the Acanthogobius-lineage (Gobiidae). The discovery of this goby in the Yellow Sea enriches our knowledge of the fish diversity and distribution of this region, and sheds some light on the ecological habitat of these gobies.

À l’aide de nos rencontres cliniques régulières avec les patients, nous proposons au fil de cet article de découvrir quelle place singulière va prendre le pansement dans l’économie psychique du sujet et comment il va opérer un traitement psychique de ce dispositif. Il nous apparaît que cette prothèse corporelle que représente le pansement peut également constituer un levier psychique et nous aider dans nos rencontres avec ces patients.
De l’erreur humaine à la faute managériale : la responsabilité et la pérennité organisationnelle en question
Authors: Teneau Gilles , Dufour Nicolas , Moulin Max
Published: October 2023

L’objet de cet article est de mettre en exergue le caractère de persévération dans l’erreur comme facteur d’irréversibilité dans la remise en cause de la pérennité de l’organisation. Cette erreur est alors constitutive d’une faute, forme particulière d’erreur au sens de J. reason (2003), dès lors qu’il s’agit de persévérer dans cette dernière une fois que l’on en a connaissance. Au travers de 3 études de cas menées en recherche-action dans des secteurs d’activité différents et d’entretiens complémentaires, l’apport de l’article est de mettre en lumière le caractère de persévération dans les choix stratégiques des dirigeants. Cette dimension de persévération liée à la surconfiance est caractéristique d’une faute de gestion. Les auteurs proposent alors d’appréhender le rôle du dirigeant au travers d’un principe de responsabilité se déclinant en une approche gestionnaire de risque.
Les entreprises face à la responsabilité sociale au Bénin
Authors: Sogbossi Bocco Bertrand , Hounton Dognon Mariette
Published: October 2023

Cette étude est une contribution au débat sur la RSE en Afrique et spécialement au Bénin. Elle répond à la question : quel est le sens que les entreprises au Bénin donnent à la responsabilité sociale ? Elle vise à déterminer la position des entreprises face à la responsabilité sociale des entreprises (RSE) au Bénin à travers l’analyse de leur management. Pour atteindre cet objectif, nous avons adopté une méthodologie qualitative inductive. Il ressort de cette étude que la plupart des entreprises ne connaissent pas la notion de la responsabilité sociale et sa démarche, mais leur gestion est marquée parfois par des signes très forts de sensibilité sociale. Elles sont toutes favorables à la prise en compte des responsabilités sociales et les considèrent non pas comme des coûts supplémentaires, mais comme des investissements à long terme ou comme un devoir. Manquent avant tout à ces engagements des lignes directrices, et l’engagement et l’incitation des pouvoirs publics.
La sociocratie : des principes à la réalité de terrain dans un centre de recherche
Authors: Douillié Geoffroy , Vandewattyne Jean , Van Daele Agnès
Published: October 2023

La sociocratie qui est à situer dans le cadre plus large du management participatif, est un mode de gouvernance basé sur la participation de tous les membres d’une organisation aux prises de décisions stratégiques et qui fonctionne à partir de quatre règles : l’organisation en cercles, le consentement, l’élection sans candidat et le double lien. Dans le but d’en étudier une mise en œuvre concrète, nous avons mené une étude dans un centre de recherche. À travers cette étude de cas, nous nous intéressons aux apports de la sociocratie mais aussi aux difficultés d’implémentation et ce, du point de vue des travailleurs concernés. Les enjeux sous-jacents et les conditions favorables à la mise en place d’un tel mode de gouvernance sont également questionnés. La méthodologie repose principalement sur des entretiens semi-directifs menés auprès de 14 travailleurs. Les résultats montrent une implémentation partielle de la sociocratie mais aussi l’existence de plusieurs indices d’une évolution culturelle vers plus de sociocratie. Les apports perçus par les travailleurs concernent principalement le décloisonnement de l’organisation. Des apports sur un plan plus individuel sont également relevés. L’étude a aussi permis de mettre en évidence plusieurs difficultés ressenties par les travailleurs, dont un conflit de l’élitisme. Pour dépasser ces difficultés, plusieurs pistes sont évoquées.
Mieux-être au travail : gadget RH ou vrai levier de performance pour les entreprises ?
Authors: Lacan Arnaud
Published: October 2023

Le bien-être au travail est aujourd’hui un enjeu majeur pour les entreprises. En effet, l’émergence de la postmodernité et son florilège de valeurs nouvelles a modifié profondément les désirs des collaborateurs. Pour répondre à ces derniers, l’entreprise doit réinventer ses politiques RH et ses pratiques managériales. L’enjeu est d’autant plus fort que toutes les études et observations montrent que le bien-être au travail est facteur de performance pour l’entreprise. Cet article propose donc d’abord une nouvelle grille de lecture des désirs intimes des collaborateurs et des pratiques managériales pour y répondre, puis une étude des impacts du mieux-être au travail sur la performance collective, avant d’esquisser des propositions de postures managériales susceptibles d’organiser cette recherche de mieux-être au travail.
Les déterminants de l’intention entrepreneuriale des étudiants camerounais
Authors: Tchagang Emmanuel
Published: October 2023

Cette étude a pour but de rechercher les facteurs explicatifs de l’intention de créer une entreprise par les étudiants camerounais. La validation de deux modèles d’intention combinés, le modèle de Shapero et Sokol (1982) et le modèle d’Ajzen (1991), révèle à partir d’une enquête auprès de 545 étudiants camerounais, que le désir d’agir et la faisabilité perçue sont les principaux déterminants de l’intention entrepreneuriale des étudiants. Le contexte universitaire a une influence marginale, tandis que la norme sociale, le concept de soi n’ont aucune influence. Globalement, l’effet modérateur de la propension à l’action n’est pas vérifié.
Diversité du conseil d’administration et politique de dividende des grands groupes bancaires systémiques : théories et investigations empiriques
Authors: Vernier Éric , Dannon Hodonou , Dumoulin Régis
Published: October 2023

Cet article étudie la relation entre la diversité du conseil d’administration des 30 grands groupes bancaires systémiques et leur politique de distribution de dividende. L’analyse de données de panel cylindré grâce à l’estimateur GMM (Generalised Method of Moments) a été mobilisée sur la période 2010-2015. Globalement, les résultats obtenus confirment l’hypothèse de lissage des dividendes développée par Lintner (1956) et indiquent que les baisses de dividende sont rarement observées dans le cas des grands groupes bancaires systémiques. En outre, la proportion des femmes siégeant au conseil d’administration et celle des administrateurs indépendants influencent négativement et significativement la distribution de dividende. Il y va de même de la fréquence des réunions du conseil d’administration et de l’augmentation des comités spécialisés de ce conseil. Cependant, la dualité du style de leadership est positivement et significativement reliée à la distribution de dividende. Les effets de la taille, des stocks de liquidité disponibles et des opportunités de croissance sur la distribution de dividende des groupes bancaires systémiques sont conformes à la théorie de Fama & French (2001).
