Personality Traits of Women Entrepreneurs for Sustainable Food Businesses
Authors: Din Norrina , Tahir Mohd Subri , Othman Norashida , Joremi Leylawati
Published: September 2022

Objective - COVID-19 is the worst in the history of pandemics. Small business survival has been jeopardized in this challenging situation, although entrepreneurs desire to strategize their plans to sustain their business. Other than strategies, psychological characteristics were found to be significant factors for sustaining business among entrepreneurs. Research on the psychological characteristics of entrepreneurs has long been conducted. However, the information is scarce in terms of the main psychological characteristics of entrepreneurs, especially during the COVID-19 pandemic. Therefore, this study explores the Bumiputera women entrepreneurs' psychological characteristics that enable the business's survival.
Methodology/Technique – Using purposive sampling, a semi-structured interview was conducted with Bumiputera women entrepreneurs in the food business located in Penang. Out of 60, only 17 agreed to participate.
Finding – The result of the thematic analysis revealed that self-confidence, creativity, and proactivity were identified as the primary key to sustaining their business. Surprisingly, the entrepreneur's creativity highlighted a new shed to hybrid Malay and Japanese cuisine to produce lemang sushi. Additionally, the study's findings have few consequences for entrepreneurs, societies, and the government. Although the pandemic has had a disastrous effect on health and lifestyle activities, there is always a spark of hope for introducing considerable ways to fulfill entrepreneurial desires and serve the community.
Novelty – As a result, entrepreneurs are incentivized to boost the economy as a person in society by delivering sustainable services to the community.

Published: September 2022

Objective - Demands for Urban Retirement Environments have attracted much attention in the industry for senior citizens. This study aimed to examine the socio-demographic profile and antecedent factors influencing adults' decisions and preparedness toward retirement environment facilities in two urban settings. Methodology/Technique – This study uses a quantitative cross-sectional approach using the descriptive-normative survey method with a modified self-administered questionnaire. Data was collected in Greater Kuala Lumpur and Kota Kinabalu. Mail survey respondents returned 369 usable questionnaires yielding a 14.5% response rate. Hypotheses were analyzed using the structural model. Finding – The study found that the urban population was receptive to retirement preparation with financial Planning and health insurance commitments. The majority, 72%, engaged with exercise and 80% with lifelong learning activities and profited from a better health status. In addition, 69% to 72% were more well-prepared to welcome home care and daycare service packages. However, it was a natural preference to accept lower fees up to RM300, even though most hold health insurance plans, and the higher-income respondents with more than RM75,000 annual income showed a willingness to pay between RM1000 to RM5000 for institutional care services. Novelty – This study has examined significant relationships between the level of retirement preparedness, namely the three elements, financial Planning, health insurance, and lifelong Learning, with their socio-demographic profile. It also provides the gaps and potential greenfield versus brownfield areas for investment. The aged care providers and insurance companies have a potential niche market in developing and collaborating using the above elements in developing retirement insurance and investment package strategies. Together they can generate more options to build sustainable retirement environment business agenda.

Financial Literacy as a Strategic issue: A survey from Portuguese Higher Education Students
Authors: Antão Mário , Silvestre Cláudia , Martinho Carla , Negas Mário
Published: September 2022

Objective – This paper addresses the financial literacy issue in different countries and contexts, comparing it with the financial Literacy of Portuguese Higher Education Institutions (HEI) students. The objective is to identify the growing need for knowledge in this area and to correct the population's attitude and behavior. This study identifies the main conditioning variables of the financial Literacy of this group of individuals, contributing to developing conditions and procedures that would improve the financial Literacy of European students as an essential element of their personal and professional success.
Methodology –This study was based on a survey using a sample of 1017 students from 18 institutions. Ordinal regression was used to determine the predictors of financial Literacy.
Findings – The literature review shows different results of structural aspects of the same central questions related to financial Literacy among HEI students. The conclusions of the study are in line with the literature review. Nevertheless, empirical research shows that Portuguese students' financial Literacy is lower than students from other countries, highlighting the need to improve their knowledge in this area by correcting the focus group's attitude and behavior. The study identifies the main conditioning variables of the financial Literacy of this group of individuals.
Novelty – HEI students who study finance present a higher level of financial knowledge and relatively more confidence in managing their money, the same for working students. No significant gender differences are observed, and these facts align with some authors. However, it is noteworthy to mention that several researchers observe alternative conclusions. This study shows an evolution of the situation followed twelve years earlier, with the same population, but confirms HEI students' low financial literacy level. This research also contributes to the main study promoted by OECD and included on the 2030 agenda of the United Nations (U.N.).

Published: September 2022

One of the factors ensuring the stable development of agriculture is high-quality and reliable equipment. Today, the development of hydraulic drives has largely led to its widespread use in agricultural machinery and tractors. One of the systems fully hydrogenated in heavy agricultural machinery is the steering system. Hydrovolume steering system has the following advantages - compactness, freedom in the layout of the machine, high efficiency, accuracy, the ability to transfer significant effort to the steered wheels with minimal effort of the operator. Disadvantages include certain restrictions when the associated load on the steered wheels when turning. This parameter is one of the indicators of the quality of hydrovolume steering systems and the minimum effort at which the process of assembling the wheels begins, is regulated by international standards.
The article performs mathematical modeling of the hydrovolume steering system. The mathematical model consists of the equations of continuity of flows of the working fluid, the equations of moments and the Lagrange equation of the 2nd kind, which describes the operation of the planetary gearbox. The search for solutions of this model was carried out using the original software, built on the basis of the Runge-Kutta-Feldberg method with an automatic integration step. As a result of the analysis of the received transient processes areas of steady work were constructed that allowed to receive a ratio of parameters of system at which its steady work is provided. The proposed design solution allowed to increase the limit value of the associated load in excess of which there is a spontaneous movement of the steered wheels. The analysis of the workload at the associated load had a significant impact on the values of the overlap of the working edges on any work of the system under the action of the associated load, and the correct selection of these floors can achieve significant quality improvement.

Essence, approaches to assessment and interrelation of the total economic and financial potential of agro-food sector companies
Authors: Mickiewicz Bartosz , Volkava Katsiaryna
Published: September 2022

The study found that the competitiveness of companies in the agro-food sector is determined by its total economic potential, by which we mean the availability of resources at its disposal that allow organizing the efficient production of goods in order to meet market needs and ensure sustainable development of the company under changing external and internal environment. The total economic potential of companies in the agro-food sector structurally consists of many types, components of the potential, closely interconnected and aimed at achieving the set goals. In the structure of the total economic potential of companies in the agro-food sector, the following structural elements should be distinguished: material, intellectual, information technology, innovative and financial potentials. A systematic study of the total potential of companies or its individual elements is the basis for making effective management decisions and their sustainable development. The author's definition of the category "total economic potential of the agro-food sector companies" is given and can be explored: as actually achieved (resource, productive), which characterizes the level of use of the company’s capabilities; and as a promising (target) economic potential–these are the potential capabilities of companies at the expense of resources that are not used at a given time due to various circumstances, but which can be achieved by improving management.
Zwicky Transient Facility and Globular Clusters: Calibration of the gr-band Absolute Magnitudes for the Yellow Post-asymptotic-giant-branch Stars

Published: September 2022

We present the first absolute calibration for the yellow post-asymptotic-giant-branch (PAGB) stars in the g and r band based on time-series observations from the Zwicky Transient Facility. These absolute magnitudes were calibrated using four yellow PAGB stars (one nonvarying star and three Type II Cepheids) located in the globular clusters. We provide two calibrations of the gr-band absolute magnitudes for the yellow PAGB stars, by using an arithmetic mean and a linear regression. We demonstrate that the linear regression provides a better fit to the g-band absolute magnitudes for the yellow PAGB stars. These calibrated gr-band absolute magnitudes have a potential to be used as Population II distance indicators in the era of time-domain synoptic sky surveys.
On the Unusual Variability of 2MASS J06195260–2903592: A Long-lived Disk around a Young Ultracool Dwarf

We present the characterization of the low-gravity M6 dwarf 2MASS J06195260-2903592, previously identified as an unusual field object based on its strong IR excess and variable near-IR spectrum. Multiple epochs of low-resolution (R ≈ 150) near-IR spectra show large-amplitude (≈0.1–0.5 mag) continuum variations on timescales of days to 12 yr, unlike the small-amplitude variability typical for field ultracool dwarfs. The variations between epochs are well-modeled as changes in the relative extinction (ΔA

V
≈ 2 mag). Similarly, Panoramic Survey Telescope and Rapid Response System 1 optical photometry varies on timescales as long as 11 yr (and possibly as short as an hour) and implies comparable A

changes. Near Earth Object Wide-field Infrared Survey Explorer mid-IR light curves also suggest changes on 6 month timescales, with amplitudes consistent with the optical/near-IR extinction variations. However, near-IR spectra, near-IR photometry, and optical photometry obtained in the past year indicate that the source can also be stable on hourly and monthly timescales. From comparison to objects of similar spectral type, the total extinction of 2MASS J0619-2903 seems to be A

V
≈ 4–6 mag, with perhaps epochs of lower extinction. Gaia Early Data Release 3 (EDR3) finds that 2MASS J0619-2903 has a wide-separation (1.′2 = 10,450 au) stellar companion, with an isochronal age of

New Dynamical State and Habitability of the HD 45364 Planetary System
Authors: Li Zhexing , Kane Stephen R. , Dalba Paul A. , Howard Andrew W. , Isaacson Howard T.
Published: September 2022

Planetary systems with multiple giant planets provide important opportunities to study planetary formation and evolution. The HD 45364 system hosts two giant planets that reside within the habitable zone (HZ) of their host star and was the first system discovered with a 3:2 mean motion resonance (MMR). Several competing migration theories with different predictions have previously provided explanations regarding the observed resonance through dynamical simulations that utilized limited data. Here, over ten years since the original discovery, we revisit the system with a substantially increased radial velocity (RV) sample from High Accuracy Radial Velocity Planet Searcher spectrograph and High Resolution Echelle Spectrometer that significantly extends the observational baseline. We present the revised orbital solutions for the two planets using both Keplerian and dynamical models. Our RV models suggest orbits that are more circular and separated than those previously reported. As a result, the predicted strong planet–planet interactions were not detected. The system dynamics were reanalyzed, and the planet pair was found to exhibit apsidal behavior of both libration and circulation, indicating a quasi-resonance state rather than being truly in MMR. The new orbital solution and dynamical state of the system confirm migration models that predicted near-circular orbits as the preferred scenario. We also study the habitability prospects of this system and found that an additional Earth-mass planet and exomoons in the HZ are possible. This work showcases the importance of continued RV observations and its impact on our knowledge of the system’s dynamical history. HD 45364 continues to be an interesting target for both planetary formation and habitability studies.
Potential Signature of Population III Pair-instability Supernova Ejecta in the BLR Gas of the Most Distant Quasar at z = 7.54*

Published: September 2022

The search for Population III stars has fascinated and eluded astrophysicists for decades. One promising place for capturing evidence of their presence must be high-redshift objects; signatures should be recorded in their characteristic chemical abundances. We deduce the Fe and Mg abundances of the broadline region (BLR) from the intensities of ultraviolet Mg ii and Fe ii emission lines in the near-infrared spectrum of UKIDSS Large Area Survey (ULAS) J1342+0928 at z = 7.54, by advancing our novel flux-to-abundance conversion method developed for quasars up to z ∼ 3. We find that the BLR of this quasar is extremely enriched, by a factor of 20 relative to the solar Fe abundance, together with a very low Mg/Fe abundance ratio: [Fe/H] = +1.36 ± 0.19 and [Mg/Fe] =−1.11 ± 0.12, only 700 million years after the Big Bang. We conclude that such an unusual abundance feature cannot be explained by the standard view of chemical evolution that considers only the contributions from canonical supernovae. While there remains uncertainty in the high-mass end of the Population III initial mass function, here we propose that the larger amount of iron in ULAS J1342+0928 was supplied by a pair-instability supernova (PISN) caused by the explosion of a massive Population III star in the high-mass end of the possible range of 150–300 M
⊙ . Chemical evolution models based on initial PISN enrichment well explain the trend in [Mg/Fe]-z all the way from z < 3 to z = 7.54. We predict that stars with very low [Mg/Fe] at all metallicities are hidden in the galaxy, and they will be efficiently discovered by ongoing new-generation photometric surveys.
Walk on the Low Side: LOFAR Explores the Low-frequency Radio Emission of GASP Jellyfish Galaxies

Jellyfish galaxies, characterized by long filaments of stripped interstellar medium extending from their disks, are the prime laboratories to study the outcomes of ram pressure stripping. At radio wavelengths, they often show unilateral emission extending beyond the stellar disk, and an excess of radio luminosity with respect to that expected from their current star formation rate. We present new 144 MHz images provided by the LOFAR Two-metre Sky Survey for a sample of six galaxies from the GASP survey. These galaxies are characterized by a high global luminosity at 144 MHz (6−27 × 1022 W Hz−1), in excess compared to their ongoing star formation rate. The comparison of radio and Hα images smoothed with a Gaussian beam corresponding to ∼10 kpc reveals a sublinear spatial correlation between the two emissions with an average slope of k = 0.50. In their stellar disk we measure k = 0.77, which is close to the radio-to-star formation linear relation. We speculate that, as a consequence of the ram pressure, in these jellyfish galaxies cosmic ray transport is more efficient than in normal galaxies. Radio tails typically have higher radio-to-Hα ratios than the disks, thus we suggest that the radio emission is boosted by electrons stripped from the disks. In all galaxies, the star formation rate has decreased by a factor ≤10 within the last ∼108 yr. The observed radio emission is consistent with the past star formation, so we propose that this recent decline may be the cause of their radio luminosity-to-star formation rate excess.

Published: September 2022

International efforts are underway to explore the Moon’s south polar region with robotic and human missions. These missions will address key scientific and exploration objectives in a region rich with possibilities, designed to develop a sustained lunar presence. To assist a trade study among six potential landing sites identified for Artemis astronauts, we examined two of those sites: 007 and 011. We find that (1) many craters in the vicinity of Site 007 excavated and expose ejecta from Shackleton and Slater; additionally, numerous craters around Site 011 expose Cabeus and de Gerlache ejecta; (2) dense boulder fields occur near a large permanently shadowed region (PSR) at Site 007 and near the point of highest surface illumination in Site 011, which may affect landing and surface exploration activities; (3) despite some surface roughness, both sites 007 and 011 are traversable and contain exploration targets suitable for in situ resource utilization; (4) sites 007 and 011 receive higher average illumination than previously reported for sites 001 and 004; and (5) PSRs, seasonally shadowed regions, and cold traps at both sites offer opportunities to sample volatiles.

Present-day environmental conditions on Titan, the largest moon of Saturn, may do active geomorphic work on its surface. On Earth, the hydrologic water cycle erodes and weathers its continents. Deluges over elevated terrain create debris flows and sheetfloods that spread into alluvial fans as the topographic slope decreases. Mars also shows evidence of past fluvial erosion, but fluvial activity cannot be ongoing in the present. On Titan, however, fluvial erosion is likely ongoing. In this study, we focus on understanding the environmental controls on the spatial distributions of alluvial fans, a type of fluvial depositional feature observed globally on the surface of Titan. To do this, we utilize probabilistic models to determine the strength of spatial correlations between spatial distributions of alluvial fans and present-day environmental factors. We find that the spatial distribution of alluvial fans on Titan correlates well with several present-day environmental conditions, including average precipitation, precipitation variability, and elevation. Based on our model, we also provide predictions of the likelihood of alluvial fan occurrences for areas of Titan not mapped with Cassini, which may be of interest for future missions to Titan.

Les débuts du socialisme républicain irlandais : entre nationalisme, socialisme et internationalisme 1896-1903
Authors: Augot Lise
Published: September 2022

Le socialisme républicain apparaît en Irlande en 1896, il est théorisé par James Connolly et se déploie à Dublin à partir d’un parti, l’ Irish Socialist Republican Party (ISRP). Le parti se dote d’un programme dans lequel on voit apparaître les fondements du socialisme républicain soit la création d’un pont entre le projet socialiste et le nationalisme républicain par l’instauration d’une république irlandaise. Ce travail s’attache à montrer comment les acteurs du socialisme républicain théorisent leur mouvement et agencent trois notions qui paraissaient contradictoires : le nationalisme, le socialisme et l’internationalisme. Nous étudierons les fondements de cette théorie inédite qui s’est imposée dans le paysage politique irlandais entre 1896 et 1903 et tout au long du xxi e  siècle.
Jaurès a-t-il été trop indulgent à l’égard de Gustave Hervé ?
Authors: Pinard Joseph
Published: September 2022

Cet article apporte des éléments complémentaires sur la réception des thèses antimilitaristes de Gustave Hervé et sur la trajectoire en général de ce dernier au sein des milieux socialistes, à travers le cas en particulier de la région du Doubs.
Une action antagoniste et conjointe
Authors: Beetschen André
Published: September 2022

À la suite des fortes propositions de Jean Laplanche, Daniel Widlöcher et Didier Anzieu aux Entretiens sur « La pulsion pour quoi faire ? », explorer à nouveau ce « morceau d’activité » –  Triebregung  – prend appui sur le Freud d’« Angoisse et vie pulsionnelle ». L’accent est mis sur ce qui, en 1984, fut quelque peu tenu à l’écart, mais s’impose aujourd’hui : la mise en évidence et le jeu respectif des « deux espèces de pulsions », sexuelles et de destruction. Avec le questionnement sur la satisfaction et l’origine sont examinées les formes de mixtion et de démixtion pulsionnelle, celles qui confèrent à psyché sa « bigarrure », celles où les problématiques du masochisme et du sur-moi tiennent une place centrale.
Relations bilatérales de défense entre le Royaume-Uni et la France : enjeux et perspectives après la signature de l’alliance AUKUS
Authors: Rival Xavier
Published: September 2022

La signature de l’alliance AUKUS ainsi que le retrait du Royaume-Uni de l’Union européenne invitent à un réexamen de la relation de défense franco-britannique. Fruit d’une histoire longue et complexe ayant largement contribué à forger deux États encore profondément différents, cette relation doit être appréhendée à l’échelle mondiale. En Europe, parce que les intérêts essentiels de l’un des deux pays ne pourraient être menacés sans que les intérêts essentiels de l’autre ne le soient également, les relations de défense devront rester fortes et profondes, bien que soumises à l’arbitrage des États-Unis. En Indo-Pacifique, en revanche, la poursuite d’intérêts particuliers, notamment économiques, dans le cadre de l’exportation d’armement, pourrait amener Londres et Paris à être de nouveau en compétition.
Réchauffement climatique en Arctique : une nouvelle donne géopolitique ?
Authors: Renaux Louis-Xavier
Published: September 2022

L’Arctique subit de plein fouet les effets du réchauffement climatique. Au-delà des nouvelles opportunités économiques qui devraient bousculer la gouvernance régionale, la disparition progressive mais quasiment inéluctable de la banquise risque de rebattre profondément les cartes de la géopolitique mondiale. Dans un monde où les rivalités entre les puissances se multiplient, les grands acteurs ne laisseront pas passer la carte décisive qui peut faire pencher la balance en leur faveur : l’Arctique peut-il devenir cette carte ? La position d’équilibre de la France doit l’inciter à analyser ces évolutions avec lucidité pour décider en fonction de ses intérêts et de ses ambitions.
Jeux de guerre : vers un nouvel essor
Authors: Malard Yann
Published: September 2022

Depuis quelques années, le Wargame bénéficie d’une nouvelle dynamique au sein des armées occidentales. Les jeux de guerre constituent un outil pédagogique qui permet d’embrasser les enjeux dans toute leur complexité et se les approprier de manière active. Ils offrent ainsi une alternative complémentaire peu coûteuse, flexible et évolutive aux méthodes de planification actuellement utilisées. En réduisant son aversion au risque et en se confrontant aux conséquences de ses propres décisions dans un temps contraint, le joueur développe son agilité intellectuelle, qualité indispensable au futur haut responsable militaire. La mise en place d’une organisation cohérente en France est une condition préalable indispensable au développement et à l’optimisation de cet outil.
Vers une stratégie des ressources humaines militaires moderne et durable adaptées aux défis pour l’Europe : l’exemple de la Bundeswehr
Authors: Reinhardt Markus
Published: September 2022

Ce travail met en lumière les principaux éléments du système des ressources humaines de la Bundeswehr en se concentrant sur le personnel militaire, afin d’identifier les points d’ancrage en matière de stratégie du personnel pour une éventuelle première coopération entre l’Allemagne et la France dans ce domaine également. La thèse centrale est qu’en raison de la pression au changement due aux conditions générales en matière de politique de sécurité, de société et de personnel, peut rendre judicieuse une extension des initiatives franco-allemandes, également au domaine de la RH. Il est recommandé d’adopter une approche qui pourrait conduire à des initiatives concrètes par le biais d’un nouveau format de dialogue binational.
Les futures « armes de rupture » et leur emploi possible dans les armées françaises
Authors: Michel Stanislas
Published: September 2022

Les « armes à effet dirigé », réelles technologies de rupture, pourraient révolutionner l’art de la guerre. En prenant ce virage capacitaire, notre modèle consoliderait sa cohérence en élargissant les effets militaires tout en renforçant sa crédibilité, y compris dans le champ du signalement stratégique en phase de confrontation. Il est donc essentiel d’investir le domaine à l’heure où nos compétiteurs disposent déjà d’une gamme d’armes à effet dirigé en mesure de réduire drastiquement notre liberté d’action. D’où la nécessité d’avoir également une approche défensive avec les enjeux de protection face à ces armes. En revanche, l’intégration au sein d’un modèle d’armée à budget constant pourrait imposer des choix complexes au travers de certaines évictions.
Histoire et enjeux du concept d’addiction
Authors: Edel Yves
Published: September 2022

Cet article propose une introduction générale à l’addictologie en tant que nouvelle conception anthropologique des comportements d’usages de substances psychoactives du point de vue médical, psychosocial et sociétal. Il convient d’y ajouter certaines conduites incluses en addictologie dans les addictions dites « sans produit » ou « addictions comportementales ». L’évolution des usages et des politiques publiques, les débats entre spécialistes et les découvertes en neurobiologie, permettent de brosser une introduction de l’histoire des concepts et d’en montrer les enjeux éthiques et sociaux, avec l’élaboration d’une nouvelle éducation thérapeutique basée sur la restauration de l’estime de soi et la reconquête du plaisir de vivre.
Du lien à l’acte
Authors: Baudin Claire-Anne
Published: September 2022

Dans ces travaux d’analyse d’auteurs contemporains, il apparaît que c’est du lien au Christ que provient l’agir chrétien à proprement parler. Cet agir cependant, dans sa teneur, n’est pas réservé spécifiquement aux disciples du Christ, mais il est cherché par tout homme qui veut la fraternité et l’amour du prochain. La christologie de participation ou de suivance qui est explicitée dans ces textes vient en lieu et place de la référence normative en matière de morale. La figure biblique du Christ, alors, conduit à le reconnaître dans les souffrants et à agir en conséquence. Cela engage à un agir qui, loin des théories, relève d’une injonction à l’ultime de la vie, à l’extrême de l’amour, qui n’est pas de l’ordre du confort admis.
Christologie et éthique
Authors: Chalamet Christophe
Published: September 2022

La christologie éclaire forcément l’éthique, en théologie chrétienne. Mais de quelles manières ? Au-delà de tout rapport « direct » ou « simple » qui chercherait dans la christologie des réponses toutes faites aux questions éthiques de notre temps, la réflexion christologique oriente l’éthique théologique vers le sens du rapport à autrui et au monde. Le récit de la passion de Jésus de Nazareth éclaire notre rapport aux crucifiés de notre temps, indique le chemin prioritaire de la non-violence et interdit toute légitimation des tendances belliqueuses et hégémoniques qui continuent encore aujourd’hui de déchirer l’humanité.
L’universalité des droits de l’Homme
Authors: Guyomar Mattias
Published: September 2022

L’universalité des droits humains préoccupe le juge à la Cour européenne des droits de l’Homme. Parler des droits de l’Homme ou des droits humains conduit assez naturellement à affirmer qu’ils sont universels, car l’homme est un, l’humanité est une. L’universalité des droits humains est un idéal qui cherche à réconcilier la nécessaire prise en compte du monde dans sa totalité et son unicité et le respect de la diversité culturelle, des traditions nationales, des spécificités historiques et géographiques. Une telle conception repose sur l’idée de l’éthique de la réciprocité. Il est même possible de dire que les droits humains sont des droits que nous nous reconnaissons mutuellement. C’est l’idée de l’inscription de droits dans une communauté humaine. Par le système conventionnel européen, les autorités nationales ont accepté de se soumettre au contrôle subsidiaire de la Cour qui est chargée de vérifier si, tout bien pesé, le standard minimum de protection a finalement été respecté.
