The virtual field trip format offers several advantages over a fully three-dimensional world, including its ease and cost-effectiveness in creation and development. By utilizing a 360 camera, capturing images becomes convenient, portable, and viable even in remote regions. With the amount of activity involving students and agricultural society, the potential for integrating these field trip experiences into a learning experience is significant in IPB University. Not only it able to help students understand the context before doing the actual field trip, it also able to improve their empathy to the society introduced through the virtual field trip. This research aims to present the development of a virtual reality tour to introduce digital village ecosystem to computer science students and measure its presence among the students. The 360 scenes were captured during a visit to a digital village in West Java, and an immersive learning plan was devised to introduce the digital village ecosystems. The learning path was designed based on the cone of learning principle. To evaluate the effectiveness of the virtual reality system, presence questionnaires were administered, a knowledge test was conducted, and interviews were carried out with 22 students. Research indicates that the virtual field trip successfully introduced one digital village ecosystem in Cibodas, West Java Province. Students were able to explore the village site, learn about the digital village ecosystem, and provide valuable feedback. The presence questionnaire yielded a score of 5.49 out of 7, indicating a positive immersive experience. The two are of improvements are Involvement (4.96 of 7.00) and Distraction Factor (5.20 of 7.00). The interviews identified areas for improvement, such as enhancing content quality and increasing natural interaction within the system. In conclusion, this research has laid the foundation for the IPB Immersive Field Trip Platform by developing a virtual field trip that introduces computer science students to a digital village ecosystem. The findings demonstrate promising results and provide insights for further refinement of the platform.

INTEGRATING SUSTAINABLE DEVELOPMENT INTO THEIR MARKETING STRATEGY: PRACTICES OF LEBANESE AGRI-FOOD INDUSTRIES
Authors: Davidavičienė Vida , Fayad Cendrella Abou , Gergess Marc
Published: January 2024

Amidst technological growth and its environmental implications, there’s a global push for sustainable development using ethical methods that benefit both the planet and humanity. This underscores a rising corporate trend towards sustainability. Adopting this approach requires fresh methods and technologies to influence behavior changes. Consequently, marketing, when aligned with sustainability principles, becomes a pivotal tool for businesses transitioning to sustainable practices. The food industry, like other sectors, is not exempt from these considerations. This article focuses on examining how food industries in Lebanon are incorporating sustainable development principles into their marketing strategies. By studying their approaches, we aim to identify the level of integration of sustainability within the marketing practices of these industries, identify gaps, and to bring the future scientific research directions in marketing management. Thus, this research is conducted following the post-positivist paradigm and following a hypothetical-deductive approach. Hence the qualitative research and expert evaluation used to collect data due to its applicability to the context of the study. The target respondents are managers of the agri-food industries in order to measure the good practices of sustainable development of these industries and their Marketing strategy based on the 4Ps. Lebanon’s distinct challenges, from environmental to economic, call for specialized solutions. Achieving sustainability involves grasping local nuances, engaging stakeholders, and connecting different sectors. Sustainable marketing emphasizes local products and community ties, offering potential for significant change. The study indicates agri-food businesses mainly focus on environmental and economic elements. Yet, the research faced hurdles, like the pandemic, highlighting the need for context-awareness.
Single Millisecond Pulsars from Dynamical Interaction Processes in Dense Star Clusters
Authors: Ye Claire S. , Kremer Kyle , Ransom Scott M. , Rasio Frederic A.
Published: January 2024

Globular clusters (GCs) are particularly efficient at forming millisecond pulsars. Among these pulsars, about half lack a companion star, a significantly higher fraction than in the Galactic field. This fraction increases further in some of the densest GCs, especially those that have undergone core collapse, suggesting that dynamical interaction processes play a key role. For the first time, we create N-body models that reproduce the ratio of single-to-binary pulsars in Milky Way–like GCs. We focus especially on NGC 6752, a typical core-collapsed cluster with many observed millisecond pulsars. Previous studies suggested that an increased rate of neutron star binary disruption in the densest clusters could explain the overabundance of single pulsars in these systems. Here, we demonstrate that binary disruption is ineffective and instead we propose that two additional dynamical processes play dominant roles: (1) tidal disruption of main-sequence stars by neutron stars and (2) gravitational collapse of heavy white dwarf binary merger remnants. Neutron stars formed through these processes may also be associated with fast radio bursts similar to those observed recently in an extragalactic GC.

h = 3 ± 1 pc) and composed of few stars, we confirm the reality of Ursa Major III/UNIONS 1 with Keck II/DEIMOS follow-up spectroscopy and identify 11 radial velocity members, eight of which have full astrometric data from Gaia and are co-moving based on their proper motions. Based on these 11 radial velocity members, we derive an intrinsic velocity dispersion of

Published: January 2024

In the forthcoming era of big astronomical data, it is a burden to find target sources from ground-based and space-based telescopes. Although machine-learning methods have been extensively utilized to address this issue, the incorporation of in-depth data analysis can significantly enhance the efficiency of identifying target sources when dealing with massive volumes of astronomical data. In this work, we focused on the task of finding active galactic nucleus (AGN) candidates and identifying BL Lacertae objects (BL Lac) or flat spectrum radio quasar (FSRQ) candidates from the 4FGL_DR3 uncertain sources. We studied the correlations among the attributes of the 4FGL_DR3 catalog and proposed a novel method, named fractal dimension–inverse discrete wavelet transform (FDIDWT), to transform the original data. The transformed data set is characterized as low-dimensional and feature-highlighted, with the estimation of correlation features by fractal dimension theory and the multi-resolution analysis by inverse discrete wavelet transform (IDWT). Combining the FDIDWT method with an improved lightweight MatchboxConv1D model, we accomplished two missions: (1) to distinguish the AGNs from others (non-AGNs) in the 4FGL_DR3 uncertain sources with an accuracy of 96.65% ± 1.32%, namely Mission A; and (2) to classify blazar candidates of uncertain type into BL Lacs or FSRQs with an accuracy of 92.03% ± 2.2%, namely Mission B. There are 1354 AGN candidates in Mission A, and 482 BL Lacs candidates and 128 FSRQ candidates were found in Mission B. The results show a high consistency of greater than 98% with the results in previous works. In addition, our method has the advantage of finding less variable and relatively faint sources than ordinary methods.
From Feast to Famine: A Systematic Study of Accretion onto Oblique Pulsars with 3D GRMHD Simulations
Authors: Murguia-Berthier Ariadna , Parfrey Kyle , Tchekhovskoy Alexander , Jacquemin-Ide Jonatan
Published: January 2024

Disk-fed accretion onto neutron stars can power a wide range of astrophysical sources ranging from X-ray binaries, to accretion-powered millisecond pulsars, ultraluminous X-ray sources, and gamma-ray bursts. A crucial parameter controlling the gas–magnetosphere interaction is the strength of the stellar dipole. In addition, coherent X-ray pulsations in many neutron star systems indicate that the star's dipole moment is oblique relative to its rotation axis. Therefore, it is critical to systematically explore the 2D parameter space of the star's magnetic field strength and obliquity, which is what this work does, for the first time, in the framework of 3D general-relativistic magnetohydrodynamics. If the accretion disk carries its own vertical magnetic field, this introduces an additional factor: the relative polarity of the disk and stellar magnetic fields. We find that depending on the strength of the stellar dipole and the star–disk relative polarity, the neutron star's jet power can either increase or decrease with increasing obliquity. For weak dipole strength (equivalently, high accretion rate), the parallel polarity results in a positive correlation between jet power and obliquity, whereas the antiparallel orientation displays the opposite trend. For stronger dipoles, the relative-polarity effect disappears, and jet power always decreases with increasing obliquity. The influence of the relative polarity gradually disappears as obliquity increases. Highly oblique pulsars tend to have an increased magnetospheric radius, a lower mass accretion rate, and enter the propeller regime at lower magnetic moments than aligned stars.

Authors: Obaid Khalid Ali , Fawzi Hayder Adnan
Published: January 2024

Aim: Evaluation of the anti-aging properties of Empagliflozin (EMP) associated with the aging process in mice.

Methods: The mice were allocated into four groups: negative control received normal saline without receiving D-galactose (DGA); all the three other groups received DGA (200 mg/kg/day orally) for eight weeks; the second group received normal saline; the third group received vitamin C, the final group received EMP and continued for another eight weeks.

Results: Treatment with EMP reduced the levels of TNF-α, IL-1β, and MDA levels significantly compared to induction group (91.7±9.6 ng/ml, 30.6±5.5 pg/ml, and 66.7±8.3 ng/ml vs. 304.0±102.9 ng/ml, 70.2±6.8 pg/ml, and 204.7±56.9 ng/ml; respectively), while levels of GSH-Px were significantly increased (3.3±0.6 ng/ml vs. 0.3±0.2 ng/ml). In addition, EMP increases the level of both COL-1 and COL-3 compared to the induction group (1,783.6±186.9, and 1,583.6±186.9, vs. 885.7±242.5, and 685.7±242.5 pg/ml; respectively).

Conclusion: EMP positively affects several aging parameters in mice.
New deep-sea species of Aborjinia (Nematoda, Leptosomatidae) from the North-Western Pacific: an integrative taxonomy and phylogeny
Authors: Zograf Julia K. , Semenchenko Alexander A. , Mordukhovich Vladimir V.
Published: January 2024

Marimermithid nematodes parasitising invertebrates are mainly found in the deep-sea environments. Several adult and juvenile specimens marimermithids of the genus Aborjinia have been found in bottom sediments and inside Polychaeta during recent cruises to the Kuril-Kamchatka trench and the Kuril Basin (the Sea of Okhotsk). New species are described based on integrative study. Aborjinia profundasp. nov. differs from A. eulagiscae by the location of the ventral gland cell bodies (posterior to the nerve ring vs posterior to the cardia), by the smaller body size (23–28 mm vs 103–132 mm) and shorter tail (193–263 µm vs 500–850 µm). BI and ML phylogenetic analyses based on 18S and 28S rDNA suggest that genus Aborjinia belongs to the family Leptosomatidae. Based on molecular and morphological characters the new genus Paraborjiniagen. nov. is proposed for A. corallicola. Within the family Leptosomatidae the new genus differs from all genera except Aborjinia by its endoparasitic lifestyle and hologonic ovaries. Paraborjiniagen. nov. differs from Aborjinia by the position of cephalic sensitive organs (outer labial and cephalic papillae in two separate circles vs outer labial and cephalic papillae in one circle) and by the parasitic adult (vs free-living in Aborjinia).

A new species of xenodermid snake, Achalinus nanshanensis H. Li, L.-Q. Zhu, Z.-Q. Zhang & X.-Y. Mo, sp. nov., is described based on three specimens collected from Nanshan National Park and Tongdao County of southwest Hunan Province. This new species is genetically distinct amongst its congeners with the mitochondrial COI uncorrected p-distance ranging from 4.4% (in A. yangdatongi) to 17.7% (in A. meiguensis). In addition, this new species can be distinguished from its congeners by a combination of the following morphological characters: (1) dorsal scales with 23 or 25 rows throughout and strongly keeled; (2) tail relatively longer so that TaL/ToL = 0.215–0.248; (3) length of suture between internasals significantly longer than that between prefrontals, LSBI/LSBP = 1.66–1.84; (4) single loreal scale present; (5) SPL 6 in number, with the fourth and fifth contacting eye; (6) IFL 6 in number, with the first three touching the first pair of chin shields; (7) TMP is 2-2-4/2-2(3)-4, with the anterior pair elongated and in contact with the eye; (8) ventrals 2 + 147–158; (9) subcaudals 64–77, unpaired; (10) dorsal body brownish black, with a bright yellow neck collar extending to the head and abdomen in the occipital region. The recognition of the new species increases the number of described Achalinus species to 28, of which 21 are found in China.
The organic model and ethical banking: The importance of identity
Authors: Balagué Gómez Lluís , Arimany Serrat Núria , Amat Salas Oriol
Published: January 2024

Purpose: The aim of this work is to highlight the advantages of applying the Organic Model to organizations. It considers the example of European Ethical Banking, which came about as the result of the impetus of this model. This work highlights the trajectory of Ethical Banking in Spain and examines why it has not been affected by a crisis that triggered the disappearance of dozens of centennial Savings Banks.Design/methodology: An exploratory methodology is used, consisting of a bibliographic search for the influence of the Organic Model on the creation of European Ethical Banking. The history of Ethical Banking in Spain is also analyzed, contrasting it with that of the Savings Banks in the same period. Interviews are included with prominent individuals associated with Ethical Banking and the Organic Model.Findings: The Organic Model places paramount importance on Identity in organizations. Ethical Banking and the Savings Banks had similar fundamental impulses, but the latter gradually lost their identity. This work relates the crisis that led to the disappearance of the Savings Banks to their loss of Identity. In the same context, Ethical Banking was reinforced in Spain.Originality/value: The structural division of the Organic Model to analyze organizations (with their own culture and identity, people, processes and resources) facilitates the fulfillment of their purpose and preserves the influence of values in decision-making. The Organic Model provides coherence to the members of the organization and aligns them with its identity. The economic results are not the ultimate goal, but the consequence of efficiently carrying out the mission, and at the same time they provide positive value to society, culture and the environment. It is a shared benefit.
Genomic characterization of a multidrug-resistant uropathogenic Escherichia coli and evaluation of Echeveria plant extracts as antibacterials

Published: January 2024

Uropathogenic Escherichia coli (UPEC) is the most common bacterial agent associated with urinary tract infections, threatening public health systems with elevated medical costs and high morbidity rates. The successful establishment of the infection is associated with virulence factors encoded in its genome, in addition to antibacterial resistance genes, which could limit the treatment and resolution of the infection. In this sense, plant extracts from the genus Echeveria have traditionally been used to treat diverse infectious diseases. However, little is known about the effects of these extracts on bacteria and their potential mechanisms of action. This study aims to sequence a multidrug-resistant UPEC isolate (UTI-U7) and assess the multilocus sequence typing (MLST), virulence factors, antimicrobial resistance profile, genes, serotype, and plasmid content. Antimicrobial susceptibility profiling was performed using the Kirby-Bauer disk diffusion. The antibacterial and anti-adherent effects of the methanol extracts (ME) of Echeveria (E. craigiana, E. kimnachii, and E. subrigida) against UTI-U7 were determined. The isolate was characterized as an O25:H4-B2-ST2279-CH40 subclone and had resistant determinants to aminoglycosides, β-lactams, fluoroquinolones/quinolones, amphenicols, and tetracyclines, which matched with the antimicrobial resistance profile. The virulence genes identified encode adherence factors, iron uptake, protectins/serum resistance, and toxins. Identified plasmids belonged to the IncF group (IncFIA, IncFIB, and IncFII), alongside several prophage-like elements. After an extensive genome analysis that confirmed the pathogenic status of UTI-U7 isolate, Echeveria extracts were tested to determine their antibacterial effects; as an extract, E. subrigida (MIC, 5 mg/mL) displayed the best inhibitory effect. However, the adherence between UTI-U7 and HeLa cells was unaffected by the ME of the E. subrigida extract.
Desplazamiento del Hábitat de Macrolíquenes del Bosque Montano en un Escenario de Calentamiento Global en el Noreste de los Andes Venezolanos
Authors: Marcano Vicente , Castillo Laura
Published: January 2024

Se estimaron los riesgos de pérdida “local” y “total” de hábitats de macrolíquenes considerando la migración ascendente debido al calentamiento “global” previsto para el presente siglo por el IPCC. Para tal fin, se realizaron muestreos aleatorios en el sotobosque de un bosque montano, parque nacional Sierra Nevada de Mérida, Venezuela. Se escogió una transecta en el rango entre los 2100–3100 msnm. Con el fin de demostrar la representatividad del muestreo, se evaluó el desempeño de los estimadores no paramétricos Chao 1 y 2, Jacknife 1 y 2. Los resultados revelaron 1200 individuos representados por 401 muestras, 38 géneros, 145 especies, ocho especies endémicas y tres especies nuevas; 94 especies en el bosque montano bajo y 90 especies en el bosque montano alto; 102 presentaron una distribución altitudinal “exclusiva” al bosque montano, mientras 43 especies “no-exclusiva”. La alta proporción de especies “únicas” y “duplicadas”, así como de “singletones” y “doubletones”, está relacionada con la alta diversidad y endemismo (10,78%.) y con una variedad de microclimas como consecuencia de la topografía irregular en la transecta. El análisis de desplazamiento de hábitat por incremento de temperatura (ΔT) indica que el 56,86% de las especies estarían en riesgo de desaparición por pérdida de hábitat ante un ΔT ≤ 0,5°C; el 69,60% de las especies estarían en riesgo de desaparición por pérdida de hábitat ante un ΔT ≤ 1°C; el 92,15% perderían su hábitat ante un ΔT ≤ 4°C; mientras el 11% de las especies (endémicas) perdería el “total” de sus hábitats ante un ΔT ≤ 1°C. Solo el hábitat local de 9 especies se conservaría con un incremento mayor a los 4°C. Palabras claves: líquenes; sotobosque; Cordillera de Mérida; pérdida de hábitat.
Le site paléochrétien Notre-Dame de la Place à Bordeaux : nouveaux acquis chronologiques

Résumé : Lors d’une fouille de sauvetage en 1983, une abside semi-circulaire avait été découverte sous l’église Notre-Dame de la Place, à proximité de la cathédrale de Bordeaux. Le contexte de la découverte et un faisceau d’indices historiques et archéologiques avaient conduit à identifier ces vestiges comme ceux de l’église Sainte-Marie. Sur la base d’un poème de Venance Fortunat, Aliette de Maillé avait proposé en 1959 que cette église ait été construite sous l’épiscopat de Léonce II entre 549 et 567. Même s’il est clair que le monde paléochrétien a fortement marqué le centre-ville de Bordeaux, il restait bien des incertitudes, notamment en ce qui concerne la chronologie des vestiges. Notre étude avait pour objectifs, d’une part, de réexaminer les données existantes avec un regard critique sur les arguments historiques et archéologiques et, d’autre part, d’acquérir des datations physiques par thermoluminescence, luminescence optiquement stimulée et archéomagnétisme sur les différentes phases de construction. La synthèse des 16 nouvelles dates obtenues a été établie par modélisation chronologique bayésienne. Les résultats nous indiquent que la date la plus probable pour la construction du bâtiment à abside se situe entre la deuxième moitié du ive et la première moitié du ve siècle. Cette nouvelle chronologie, les traits architecturaux atypiques et de nombreuses incertitudes relevées dans l’interprétation historique nous amènent à reconsidérer ces vestiges, très largement reconnus depuis près de quarante ans comme étant l’église paléochrétienne la plus ancienne attestée et préservée à Bordeaux.

Beaucoup d’entre eux ne sont pas visibles dans les sources publiées, y compris celles qui émanent des sociétés savantes provinciales, et constituent des cas limites qui interrogent la catégorie même d’« amateur en sciences ».
Savoirs d’ici, savants d’ailleurs : collecter et collectionner la Préhistoire en Bourgogne septentrionale à partir des années 1950
Authors: Torterat Gwendoline
Published: January 2024

Cet article restitue une diversité de pratiques liées à la figure de l’amateur et son évolution concrète dans le domaine patrimonial. Elles sont examinées à travers le cas de trois ramasseurs de cailloux, comme ils sont surnommés, originaires du nord de la Bourgogne. Collectionneurs de savoirs sur la Préhistoire et de belles pièces, ils ont classé dans leur réserve respective des dizaines de milliers de silex taillés que les labours remontaient à la surface de parcelles agricoles. N’utilisant aucun outil de détection, ils ont procédé par ramassage dès les années 1950, une décennie décisive qui suit la réorganisation du CNRS et la mise en place de circonscriptions archéologiques. Les responsabilités sont alors progressivement redistribuées ainsi que toute la chaîne des opérations liées à la collecte et l’étude scientifique des vestiges archéologiques.
The beginnings of the Aurignacian in a European framework: where do we stand?
Authors: Teyssandier Nicolas
Published: January 2024

Summary. This contribution is a synthesis on the development of the Aurignacian at a European scale. First, it focuses on Southwestern France to establish an evolutionary model in two successive phases: the Protoaurignacian and the Early Aurignacian. Once defined based on archaeological data (lithic and bone technologies, and when available, ornaments and graphic representations), the model is then confronted with other macro-regions of Europe in order to test its pan-European significance. The results suggest that the Protoaurignacian/Early Aurignacian chrono-cultural succession is not restricted to France and occurs at a continental scale. Moving forward, we propose new avenues to investigate the meaning of this pattern by integrating paleoanthropological and paleogenomic data, and by considering the role of settlement dynamics. We also address the relevance of the so-called ‘transitional industries’ which strictly precede the emergence of the Protoaurignacian in the regions considered.

Published: January 2024

Temple architecture can be a significant draw for tourism, as temples are often considered to be important culture and historical landmarks. Many people are drawn to temples for religious and spiritual reasons, while others are interested in the art, architecture, and history of these structures. Various styles of temple architecture can be seen in different parts of the world. Tourism related to temple architecture can take many forms, ranging from guided tours to individual temples to multi-day trip exploring entire temple complexes. During the visit, tourists may also join in the ceremonies and cultural activities to understand local culture and tradition. In addition to being cultural landmarks, temples can also have economic and social impacts on the local communities. In this chapter, the authors are exploring the potential of tourism in various temple architecture sites through different case studies.

Published: January 2024

Online learning, also referred to as e-learning or distance learning, is an educational approach that utilizes digital technologies and the Internet to deliver educational content and facilitate learning remotely. It eliminates geographical constraints, making education accessible to individuals who may have limited opportunities for on-campus learning due to location or other factors. Although many common learning and teaching activities, like lecturing and communicating, can be easily handled by modern online learning technologies, others, like the evaluation of learning outcomes with closed-book exams, are difficult. Among other issues involving students and educators, these difficulties concern educators' capacity to guarantee academic integrity when an exam is taken remotely and from a private location in the absence of a live proctor. The objective of this chapter of to highlight the issue of online learning particularly in developing countries.
Blockchain Implications and Utility for Higher Education
Authors: Baporikar Neeta
Published: January 2024

Blockchain has emerged as an important concept at the interface of ICT and higher education. Blockchain is perceived as a revolutionary technology offering a considerable impact of vast magnitude on various sectors since it enables the creation of decentralized applications programmed to run on networks and records sets of data that can be shared securely without third-party mediation. The Blockchain's emphasis on variety in terms of applications may be due to its capacity to build a trusted and decentralized contract environment. The higher education sector is, therefore, a potential user of blockchain technology due to its capacity in allowing stakeholders to validate learning records and identity management. On the other hand, higher education may be understood as a system that includes, among others, two major stakeholders, higher education institutions, (HEIs) and students. Adopting a systematic literature review and thematic content analysis, this chapter aims to understand the blockchain implications and utility in higher education.

Published: January 2024

UAV networks have become a promising approach to provide wireless coverage to regions with limited connectivity. The combination of UAV networks and technologies such as the internet of things (IoT), have resulted in an enhancement in the quality of life of people living in rural areas. Therefore, it is crucial to implement fast, low-complexity, and effective strategies for UAV placement and resource allocation. In this chapter, a deep reinforcement learning (DRL) solution, based on the proximal policy optimization (PPO) algorithm, is proposed to maximize the coverage provided to users requesting microservice-based IoT applications. In order to maximize the coverage and autonomously adapt to the environment in real time, the algorithm aims to find optimal flight paths for the set of UAVs, considering the location of the users and flight restrictions. Simulation results over a realistic scenario show that the proposed solution is able to maximize the percentage of covered users.
