The Role of Accounting Disclosure of Environmental Costs in Egyptian Industrial Companies: An Applied Study on Some Companies Listed on the Egyptian Stock Exchange
Authors: Abubaker Nagwa
Published: October 2024

This study examines the role of accounting disclosure of environmental costs in Egyptian industrial companies listed on the Egyptian Stock Exchange. The research highlights the importance of environmental accounting in promoting transparency and aiding decision-makers in investment and strategic planning. By focusing on a sample of companies, the study explores the current practices of environmental disclosure, identifying significant gaps in reporting standards and the challenges posed by the lack of comprehensive accounting frameworks. The findings reveal that while some companies disclose environmental costs, these disclosures are often limited, inconsistent, and not fully integrated into financial statements. This has led to reduced transparency and inadequate reflection of environmental liabilities. The study recommends enhancing regulatory frameworks to promote standardized environmental accounting practices and suggests tax incentives to encourage compliance. Future research should explore the implementation of environmental accounting across different industries and its potential impacts on corporate performance.
The Impact of Leave Practices on Employees’ Well-being and Organizational Performance: The Case of Morogoro Municipality, Tanzania
Authors: Kitwange Anna , Habi Raphael
Published: October 2024

Effective leave management encompasses integrated processes that involve employees, supervisors and human resource managers. The study aimed to determine the impact of leave practices on employees’ well-being and organizational performance in Morogoro Municipality. The study used a mixed approach (triangulation) qualitative and quantitative approach based on an exploratory sequential design. The study involved 200 respondents including 87(43.5%) from the Department of Education, 62(31%) from the Department of Health, and 51(25.5%) were headquarter employees. The study used multi-stage, purposive, stratified and convenience sampling techniques to select the respondents. The data were collected using semi- structured interviews, questionnaires, and documentation. The study found that supportive leave policies and practices significantly enhance employee well-being by reducing stress, preventing burnout, and promoting a healthier work-life balance. Conversely, inadequate or poorly implemented leave policies contribute to high levels of presenteeism, decreased job satisfaction, and increased turnover rates that negatively affect organizational performance. Recommendations for action include promoting work-life balance, fostering a supportive organizational culture, addressing financial constraints, streamlining leave processes, monitoring and evaluating leave practices, mitigating presenteeism, tailoring policies to local needs, and engaging with stakeholders. Implementing these measures will improve employee well-being and enhance organizational performance, resulting in a more productive and motivated workforce in Morogoro Municipality and other areas.
Advancing UAV Security with ALBERT: A Novel Attack Classification Approach
Authors: Pathak Lakshin , Shah Mahek , Bhatt Shivanshi
Published: October 2024

This paper presents an innovative approach for at- tack classification on Unmanned Aerial Vehicles (UAVs) using the ALBERT (A Lite BERT) transformer model. As UAVs become in- tegral to various applications, their vulnerability to cyberattacks poses significant security challenges. Traditional methods often struggle with detecting sophisticated and evolving threats. By leveraging ALBERT’s efficiency in handling large-scale data, this study enhances the detection and classification of various UAV attack types. We describe the system model, problem formulation, and the proposed ALBERT- based classification framework. The model’s performance is evaluated through experimental results, demonstrating improvements in accuracy, precision, and recall compared to existing methods. The findings underscore the po- tential of transformer-based models in cybersecurity, specifically in safeguarding UAV systems. This work also opens avenues for future research into broader applications of ALBERT in other cybersecurity domains. The proposed framework offers a practical solution for enhancing UAV security in real-world scenarios.
Time and trees: An eco-critical analysis of temporality in Richard powers' the overstory
Authors: Ananke Meintjes,
Published: October 2024

This essay examines the concept of temporality and the ways that it features in and charges Richard Powers’ (2018) novel titled The Overstory. The issue of time represents the ultimate paradox in the minds of numerous researchers engaged in various fields of study and the majority of studies regarding this topic are linked with myopic frameworks that reduce time to a series of “now” and “near-future” moments (Dawson 2014: 285). This essay argues that an immersion in ecological time or ‘deep time’, as depicted in The Overstory (Powers 2018), encourages a crucial understanding of the interconnectedness that exists between humans and the natural world. In order to substantiate its main argument, this essay regards The Overstory (Powers 2018) as a narrative that expands the issue of time to accommodate its more comprehensive construct as temporality and also engages with information regarding temporality, contained in numerous research articles, throughout its contents. In so doing, this essay proves that an anthropocentric immersion in ‘deep time’ via narrative technique, structure, and characters is possible in literature.
Urban agriculture in poor neighbourhoods: Case of Ekangala, Bronkhortspruit, Pretoria, South Africa
Authors: Erica N Mashanye,
Published: October 2024

Urban agriculture helps to improve food insecurity in cities, especially among poor neighbourhoods. This importance prompts many citizens to engage in urban agricultural activities worldwide. However, while there is an immense engagement of urban agriculture in cities worldwide, certain neighbourhoods in cities participate less in urban agriculture. This study focuses on Ekangala Township in Pretoria, where there is less engagement in urban agriculture. Questions as to why there is less participation in urban agriculture in this specific township will be answered in this paper. Disabling and enabling factors of urban agriculture are explored in this study by focussing on the laws and policies of urban agriculture implemented and used in this neighbourhood, spatial justice issues, and other factors contributing to the urban agricultural activities of the township. Thirty households were interviewed using a stratified random sampling method, where fifteen households were those partaking in urban agriculture and fifteen were those that did not. Different ways of integrating innovative and alternative forms of urban agriculture in this neighbourhood will be explored using the existing factors contributing to the engagement and disengagement of urban agriculture.

We present the discovery of TOI 762 A b and TIC 46432937 b, two giant planets transiting M-dwarf stars. Transits of both systems were first detected from observations by the NASA TESS mission, and the transiting objects are confirmed as planets through high-precision radial velocity observations carried out with Very Large Telescope/ESPRESSO. TOI 762 A b is a warm sub-Saturn with a mass of 0.251 ± 0.042 M
J, a radius of 0.744 ± 0.017 R
J, and an orbital period of 3.4717 days. It transits a mid-M-dwarf star with a mass of 0.442 ± 0.025 M
☉ and a radius of 0.4250 ± 0.0091 R
☉. The star TOI 762 A has a resolved binary star companion, TOI 762 B, that is separated from TOI 762 A by 3.″2 (∼319 au) and has an estimated mass of 0.227 ± 0.010 M
☉. The planet TIC 46432937 b is a warm super-Jupiter with a mass of 3.20 ± 0.11 M
J and radius of 1.188 ± 0.030 R
J. The planet’s orbital period is P = 1.4404 days, and it undergoes grazing transits of its early M-dwarf host star, which has a mass of 0.563 ± 0.029 M
☉ and a radius of 0.5299 ± 0.0091 R
☉. TIC 46432937 b is one of the highest-mass planets found to date transiting an M-dwarf star. TIC 46432937 b is also a promising target for atmospheric observations, having the highest transmission spectroscopy metric or emission spectroscopy metric value of any known warm super-Jupiter (mass greater than 3.0 M
J, equilibrium temperature below 1000 K).
Structured Jet Model for Multiwavelength Observations of the Jetted Tidal Disruption Event AT 2022cmc
Authors: Yuan 袁 Chengchao 成超 , Zhang 张 B. Theodore 兵 , Winter Walter , Murase Kohta
Published: October 2024

AT 2022cmc is a recently documented tidal disruption event that exhibits a luminous jet, accompanied by fast-declining X-ray and long-lasting radio and millimeter emission. Motivated by the distinct spectral and temporal signatures between the X-ray and radio observations, we propose a multizone model involving relativistic jets with different Lorentz factors. We systematically study the evolution of faster and slower jets in an external density profile, considering the continuous energy injection rate associated with time-dependent accretion rates before and after the mass fallback time. We investigate time-dependent multiwavelength emission from both the forward shock (FS) and reverse shock (RS) regions of the fast and slow jets, in a self-consistent manner. Our analysis demonstrates that the energy injection rate can significantly impact the jet evolution and subsequently influence the lightcurves. We find that the X-ray spectra and lightcurves could be described by electron synchrotron emission from the RS of the faster jet, in which the late-time X-ray upper limits, extending to 400 days after the disruption, could be interpreted as a jet break. Meanwhile, the radio observations can be interpreted as a result of synchrotron emission from the FS region of the slower jet. We also discuss prospects for testing the model with current and future observations.
The Origins of Narrow Spectra of Fast Radio Bursts
Authors: Kumar Pawan , Qu Yuanhong , Zhang Bing
Published: October 2024

Observations find that some fast radio bursts (FRBs) have extremely narrowband spectra, i.e., Δν/ν
0 ≪ 1. We show that, when the angular size of the emission region is larger than the Doppler beaming angle, the observed spectral width (Δν/ν
0) exceeds 0.58 due to the high-latitude effects for a source outside the magnetosphere, even when the spectrum in the source’s comoving frame is monochromatic. The angular size of the source for magnetospheric models of FRBs can be smaller than the Doppler beaming angle, in which case this geometric effect does not influence the observed bandwidth. We discuss various propagation effects to determine if any could transform a broad-spectrum radio pulse into a narrow spectrum signal at the observer’s location. We find that plasma lensing and scintillation can result in a narrow bandwidth in the observed spectrum. However, the likelihood of these phenomena being responsible for the narrow observed spectra with Δν/ν
0 < 0.58 in the fairly large observed sample of FRBs is exceedingly small.

We present an enhanced version of the publicly available Stripe 82X catalog (S82-XL), featuring a comprehensive set of 22,737 unique X-ray point sources identified with a significance ≳4σ. This catalog is four times larger than the original Stripe 82X catalog, by including additional archival data from the Chandra and XMM-Newton telescopes. Now covering ∼54.8 deg2 of nonoverlapping sky area, the S82-XL catalog roughly doubles the area and depth of the original catalog, with limiting fluxes (half-area fluxes) of 3.4 × 10−16 (2.4 × 10−15), 2.9 × 10−15 (1.5 × 10−14), and 1.4 × 10−15 (9.5 × 10−15) erg s−1 cm−2 across the soft (0.5–2 keV), hard (2–10 keV), and full (0.5–10 keV) bands, respectively. S82-XL occupies a unique region of flux-area parameter space compared to other X-ray surveys, identifying sources with rest-frame luminosities from 1.2 × 1038 to 1.6 × 1047 erg s−1 in the 2–10 keV band (median X-ray luminosity, 7.2 × 1043 erg s−1), and spectroscopic redshifts up to z ∼ 6. By using hardness ratios, we derived the obscuration of active galactic nuclei (AGNs), obtaining a median value of

The Anisotropic Circumgalactic Medium of Sub-L* Galaxies
Authors: Zhang 张 Huanian 华年 , Li 李 Miao 邈 , Zaritsky Dennis
Published: October 2024

Using stacked emission-line flux measurements of cool circumgalactic gas (CGM) in lower-mass galaxies (109.0 ≤ M
*/M
⊙ ≤ 1010.2), we measure the dependence of the emission characteristics on orientation relative to the disk plane as a function of radius and compare to what we found previously for massive (M
* > 1010.4
M
⊙) early-type galaxies. Although the line ratios (the lower [N ii]/Hα and [O iii]/Hβ) suggest an overall softer ionizing source than in the more massive galaxies, consistent with previous findings, we find the same ionization hardening signature (a higher [N ii]/Hα ratio in the inner polar region) along the polar direction at small radii that we found for the more massive galaxies. The line ratio in the inner polar bin is distinct from that measured for the inner planar bin with 99.99%, confidence and with >99.9% confidence we conclude that it lies outside the star formation regime. The effective hardening of the ionization of the CGM along the polar axis, at small radii, could indicate either relic effects of active galactic nucleus activity or shock ionization. In either case, this signature appears to be ubiquitous across the stellar mass range we are able to explore with our spectral stacking technique and currently available archival data.
Indication of Sharp and Strong Phase Transitions from NICER Observations
Authors: Lin Zidu , Steiner Andrew. W.
Published: October 2024

In this Letter, we present a new, weakly model-dependent test for “standard” equation-of-state (EoS) models that disfavor sharp and strong phase transitions by using NS mass and radius observations. We show the radii of two NSs observed by NICER (PSR J0740+6620 and PSR 0030+0451) are correlated if these two NSs are built upon standard EoS models. The radii of NSs with different masses are sensitive to the pressures at different densities, and the pressures at different densities are strongly correlated in standard EoS models. We further show that the correlation of the NS radii can be significantly weakened when additional degrees of freedom concerning the first-order phase transitions are added into the EoSs. We propose a new quantity, D
L, which measures the extent to which the linear correlation of the radii of two NSs is weakened. Our method gives a 48% identification probability (with a 5% false alarm rate) of finding beyond-standard EoS models in NICER observations. Future observations with higher measurement accuracy can confirm or rule out this identification. Our method is generalizable to any pair of NS masses and can be employed with other sets of observations in the future.

Authors: Heywood Ian , Siemion Andrew P. V. , Czech Daniel , Ertel Steve , Drew Jamie , Grattan Kyran , Wagner Kevin , Worden S. Pete
Published: October 2024

We have conducted observations of the nearby (11.46 ly) star system Procyon, using MeerKAT’s UHF (544–1087 MHz) receivers. We produce full-Stokes time and frequency integrated continuum images, as well as total intensity time series imaging at 8 s cadence, and full-Stokes vector-averaged dynamic spectra from the visibilities in order to search for transient activity such as flaring events. We detect no significant radio emission from the system, and estimate an upper limit on the circular polarization fraction of 65% (3σ confidence level). A comparison with previous Very Large Array observations places a 3σ lower limit on the spectral index between 815.5 and 8400 MHz of 0.26, however long-term significant variability over the last 33 yr cannot be ruled out without further, regular radio monitoring of the system.

We report the recent discovery of two new eruptions of the recurrent nova M31N 2017-01e in the Andromeda galaxy. The latest eruption, M31N 2024-08c, reached R = 17.8 on 2024 August 06.85 UT, ∼2 months earlier than predicted. In addition to this recent eruption, a search of archival Palomar Transient Factory data has revealed a previously unreported eruption on 2014 June 18.46 UT that reached a peak brightness of R ∼ 17.9 approximately a day later. The addition of these two eruption timings has allowed us to update the mean recurrence time of the nova. We find 〈T
rec〉 = 924.0 ± 7.0 days (2.53 ± 0.02 yr), which is slightly shorter than our previous determination. Thus, M31N 2017-01e remains the nova with the second shortest recurrence time known, with only M31N 2008-12a being shorter. We also present a low-resolution spectrum of the likely quiescent counterpart of the nova, a ∼20.5 mag evolved B star displaying an ∼14.3 days photometric modulation.
Culture matérielle scolaire et médiatisation du métier de professeur des écoles : les objets de l’école à l’écran sur la vlogosphère
Authors: Connan Pierre-Yves , Rigaudière Angélica
Published: October 2024

Nous explorons la manière dont la culture matérielle scolaire s’inscrit dans le processus de médiatisation et de valorisation du métier de professeur des écoles. Notre contribution prend pour objet deux chaînes YouTube consacrées au métier d’enseignant du premier degré, à la vie quotidienne du professeur et aux activités de classe. Nous abordons d’abord la corrélation qui existe entre la représentation des objets par les professeurs des écoles et les normes de la présentation de soi sur YouTube . Notre analyse porte ensuite sur les mises en scène et en récit du matériel scolaire : selon quels éclairages, au sens propre et au sens figuré, les objets sont-ils présentés ? Nous montrons enfin qu’en jouant avec les représentations d’une culture matérielle scolaire commune, avec la capacité des objets à relier et à s’inscrire dans le processus pédagogique, les youtubeuses font découvrir les coulisses du métier et témoignent du travail invisible de l’enseignant.
C/S Steel & Cie S.A. : Les déclinaisons fascinantes de l’aluminium façonné

Brevetées au début des années 1960, les grilles Claustral® de la C/S Steel & Cie SA ont introduit dans l’architecture de cette époque un dispositif protégeant à la fois contre les intrusions, les regards indiscrets et les rayons du soleil. Ce système réticulaire fait de bandes d’aluminium à l’orientation calculée, clipsées sur des attaches appropriées, s’est adapté à quantité de programmes sous toutes les latitudes pour répondre à des exigences fonctionnelles précises tout en conférant une impeccable sobriété aux édifices qu’il équipait. Aujourd’hui bousculé par le renouvellement des systèmes de parement à vocation purement esthétique et rejeté comme un piètre composant de l’architecture de la croissance, ce dispositif mérite d’être redécouvert pour mieux évaluer sa place dans l’histoire de l’architecture contemporaine.
Nursing Students' Attitudes Toward Women With Maternal Substance Use Disorders
Authors: Renbarger Kalyn M. , Anyango Jane , Pannell Anabella
Published: October 2024

Background

Maternal substance use disorders (SUD) have challenged relationships between women with SUD and their nurses. Nurses have reported biased attitudes toward women with SUD, which can interfere with their care. However, it is not well known how nursing students perceive women with SUD and their infants. This article describes nursing students' attitudes toward women with SUD, which can be used to inform educational strategies.

Method

An inductive content analysis was used to analyze 76 reflection papers written by nursing students at a midwestern university.

Results

Three main themes were identified: (1) stigma toward women with SUD; (2) concerns for infants with neonatal abstinence syndrome; and (3) influence of clinical experiences on attitudes toward women with SUD.

Conclusion

Nursing students need more evidence-based guidance on managing their biases as well as the biases of nurses who work in maternity settings.

Photorefractive Keratectomy: Technical Evolution, Refractive Outcomes, Corneal Wound Healing Response, and Complications
Authors: Torricelli André A. M. , Giglio Veronica B. , Garcia Renato , Santhiago Marcony R. , Bechara Samir J. , Wilson Steven E. , Monteiro Mario Luiz R.
Published: October 2024

Photorefractive keratectomy (PRK) was the first excimer laser procedure developed to treat refractive errors. The safety and efficacy of PRK established it as one of the most performed corneal refractive procedures worldwide. With the introduction of laser in situ keratomileusis (LASIK), and more recently keratorefractive lenticule extraction (KLEx) procedures, many corneal surgeons favor these newer corneal procedures as the first choice due to faster visual rehabilitation and less discomfort during the early postoperative period. Importantly, however, PRK remains a viable alternative for most corneal refractive candidates and there are many situations in which PRK remains the refractive procedure of choice. This review addresses the technical evolution of PRK—mechanical epithelial debridement versus alcohol-assisted epithelial removal versus excimer laser-assisted epithelial debridement (transepithelial) PRK—and reports the PRK refractive outcomes compared to other keratorefractive laser procedures. The corneal wound response associated with each PRK technique and the indications, limitations, and complications of PRK are reviewed to aid refractive surgeons to best position PRK in their overall practice.

A multi-step Ulm-Chebyshev-like method for solving nonlinear operator equations
Authors: Ma Wei , Zhao Ming , Li Jiaxin
Published: October 2024

In this paper, based on the Ulm-Chebyshev iterative procedure, we present a multi-step Ulm-Chebyshev-like method to solve systems of nonlinear equations $ F(x) = 0 $,

   \begin{document}$ \begin{equation*} \left\{\begin{array}{l} \quad {\bf{y}}_{n} = {\bf{x}}_{n}-B_{n}F( {\bf{x}}_{n}),\\ \quad {\bf z}_{n} = {\bf{y}}_{n}-B_{n}F( {\bf{y}}_{n}),\\ {\bf{x}}_{n+1} = {\bf z}_{n}-B_{n}F( {\bf z}_{n}),\\ \quad \bar{B}_{n} = 2B_{n}-B_{n}A_{n+1}B_{n},\\ B_{n+1} = \bar{B}_{n}+\bar{B}_{n}(2I-A_{n+1}\bar{B}_{n})(I-A_{n+1}\bar{B}_{n}),\quad n = 0,1,2,\ldots, \end{array}\right. \end{equation*} $\end{document}

where $ A_{n+1} $ is an approximation of the derivative $ F'({\bf{x}}_{n+1}) $. This method does not contain inverse operators in its expression, and does not require computing Jacobian matrices for solving Jacobian equations. We have proved that the multi-step Ulm-Chebyshev-like method converges locally to the solution with $ R $-convergence rate 4 under appropriate conditions. Some applications are given, compared with other existing methods, where the most important features of the method are shown.
Change point detection for a skew normal distribution based on the Q-function
Authors: Du Yang , Cheng Weihu
Published: October 2024

In this paper, we enhanced change point detection in skew normal distribution models by integrating the EM algorithm's Q-function with the modified information criterion (MIC). The new QMIC framework improves sensitivity and accuracy in detecting changes, outperforming the modified information criterion (MIC) and the traditional Bayesian information criterion (BIC). Due to the complexity of deriving analytic asymptotic distributions, bootstrap simulations were used to determine critical values at various significance levels. Extensive simulations demonstrate that QMIC offers superior detection capabilities. We applied the QMIC method to two stock market datasets, successfully identifying multiple change points, and highlighting its effectiveness for real-world financial data analysis.
Effect of triage training on nurses with Emergency severity index and Australian triage scale: Α quasi-experimental study
Authors: Pontisidis George , Bellali Thalia , Galanis Petros , Polyzos Nikolaos
Published: October 2024

Introduction

Triage training has positive effects on health professionals, the quality of indicators in emergency departments, and the patients. However, data on the effectiveness of triage training on nurses with two different triage scales is limited.

Objective

This study sought to evaluate the effectiveness of a triage training program in Emergency Departments (EDs), as well as the effect on the accuracy, knowledge, and skills of nurses working in the National Health System of Greece.

Methods

Α quasi-experimental study was carried out, with measurements taken pre-, post-, and three months after implementing the education program. Data were collected between March 2021 and July 2022. Eligible participants for this study included nurses employed in the hospital units of the 4th Health Region of the National Health System. A total of 117 nurses participated in the study. Skills, knowledge, and accuracy were assessed using the Emergency Severity Index and the Australian Triage Scale.

Results

After completing the training program, there was a noticeable improvement in the nurses' performance. Their triage skills displayed an overall statistically significant increase (p < 0.001) and, more crucially, in the subscales of rapid patient assessment skills, patient categorization skills, and patient allocation skills. Additionally, statistically significant increases were observed for triage knowledge and for both screening scales that measured triage accuracy, namely the Emergency Severity Index (p < 0.001) and the Australian Triage Scale (p < 0.001). In addition, the number of over-triage and under-triage cases decreased.

Conclusions

The education program had a positive impact on the nurses, resulting in a statistically significant increase in their triage skills and knowledge. Moreover, the use of both triage scales resulted in an increase in the triage accuracy. The increase in triage skills, knowledge, and accuracy decreased after three months.
Research Training: Unraveling the Research Methodological Design Challenge in Engineering Programs
Authors: Almeida Del Savio Alexandre , Galantini Velarde Katerina , Caceres Montero Ludy , Vergara Olivera Mónica Alejandra
Published: October 2024

Research training stands out as a means to develop generic competencies, potentiate lifelong learning (LL), and integrate initiatives for compliance with the 17 Sustainable Development Goals (SDGs), contributing to the development of a resilient society. Therefore, the constant promotion of a research culture within higher education institutions is an essential task for reducing the gap between scientific productivity and industry challenges and proposing solutions to real-life challenges. One of the main stages involved in any research process is the proposition of a methodological design: a detailed plan conceived and later developed to answer the research questions. Nevertheless, within the engineering context, even though a wide range of methodological designs are considered, these are not always explicitly stated in research papers, so at the undergraduate level there is an absence of more precise guidelines that allow a more concise orientation. Consequently, at this level, a challenge in research training is perceived. This provided a motivation: the development of a framework for the actors involved in research training at the engineering undergraduate level so that they can easily define the methodological design. In this context, the present research proposes a framework organized upon the two main phases of every research process: design and execution. The framework is expected to promote the proper use of research methodology among engineering students. Furthermore, the methodological design from 140 selected civil engineering papers from seven different knowledge fields is analyzed. Results show that 94.29% of the papers did not explicitly present the methodological design. It was concluded that there is an absence of it within the engineering field. Thus, a methodological design framework proposal for engineering students was developed to overcome this situation.

This study examines the variability of women’s persistence in various information technology (IT) roles among sample respondents while presenting how organizational policies can complement Sustainable Development Goal (SDG) number 5—gender equality. The study gathers a range of experiences and challenges through semi-structured interviews with 13 women in technology. The thematic analysis was carried out in iterative stages using the Saturate application for collaborative data coding. The results show that persistence is facilitated by the following elements: existence needs, which are met by a competitive salary and strong family ties; relationship needs, which are met by a favorable organizational climate, social relations at work, recognition of the quality of one’s own work, and gender equality; and growth needs, which are met by development and stimulation. Effective pedagogy plays a key role in encouraging women’s interest and skills in computing, starting early with mentoring and incorporating gender-sensitive teaching practices. The long-term involvement of women in the IT industry can be supported by comprehensive organizational strategies and educational reforms, which also emphasize the need for constant improvements to remove barriers.

Les fouilles archéologiques menées dans le quartier Mériadeck et ses abords témoignent de l’occupation des sols dans une zone suburbaine et humide de la capitale de cité Burdigala. À partir du ier s. apr. J.-C., des ateliers liés notamment au travail des peaux, du cuir et de la tabletterie y sont établis. Des indices forts indiquent en outre la présence de cornetiers. Au sein de ce quartier, le site de la rue Jean-Fleuret à Bordeaux (Gironde) met en lumière les techniques de travail des peaux et la production d’objets en cuir et révèle en partie l’organisation d’un tel atelier au Haut-Empire.Dans un premier état, entre 50 et 110-120 apr. J.-C., des artisans travaillent les peaux des caprinés à l’alun et/ou à l’huile d’olive, utilisent du macro-outillage lithique et des fiches métalliques en fer sans tête et collaborent avec d’autres artisans qui produisent des objets à partir de cuirs tannés de caprinés adultes et très probablement de peaux traitées à l’alun. Puis, entre 110-120 et 130-140 apr. J.-C., la spécialité de l’atelier change et les bovinés adultes sont préférés aux caprinés pour le travail des peaux. Il s’agit de la première attestation, durant l’Antiquité, d’emploi de l’alun pour le « passage en blanc » de peaux de bovinés, procédé de hongroyage que l’on pensait apparu à l’époque moderne. L’utilisation d’alun s’amplifie sur le site durant cette période, tandis que l’huile de Bétique n’est plus sollicitée.Au sein du même atelier, tabletiers et cornetiers s’associent aux artisans des peaux traitant les bovinés. Des objets en peau continuent à être assemblés, sans que l’on puisse déterminer si des cuirs tannés de bovinés sont exploités par les artisans de l’atelier.L’activité identifiée rue Jean-Fleuret cesse aux environs de 150-160 apr. J.-C., période à partir de laquelle l’espace semble mis en culture, peut-être jusqu’à la fin du iie s. Un site voisin localisé à 100 m à l’est du premier, l’îlot Fly, semble prendre le relais en termes d’activité artisanale, comme l’indiquent les batteries de cuves en bois réparties dans deux espaces desservis par un débarcadère en bois. Au iiie s., les installations y sont à leur tour abandonnées. Un dépotoir établi sur les berges du cours d’eau reflète une activité proche pratiquée par des cornetiers. L’association d’amphores de Lipari et d’amphores à huile africaines suggèrent que les artisans traitant les peaux devaient maintenir leur activité à proximité.
Discourse Studies, Corpus, and Multimodality in Urban Research
Authors: Shirazi Reza
Published: October 2024

This paper explores the contribution of Discourse Studies (DS) to urban research from two perspectives: the field of inquiry and the research corpus. It investigates which areas have utilised DS in their research and why, as well as which types of discursive modes have been subjected to analysis. An analysis of 126 publications suggests that DS has been widely utilised to investigate urban questions in urban planning and theory, urban policy, housing research, and environmental policy; this capacity can be expanded to other fields of urban research. The study also finds out that the corpus of analysis has mainly remained monomodal, limited to one item or multiple items of the same type, predominantly text-based materials. To address this problem, the corpus of the analysis should be diversified to recognize the multimodality of discourse. This entails encompassing a variety of non-verbal modes such as images, music, gestures, moving images, soundtracks, and 3D objects. The paper concludes by pinpointing directions towards which future research should progress in order to overcome the challenges of utilising DS in urban research.Discourse Studies, Discourse, Urban Studies, Urban Research, Multimodality

Authors: Gustafson Jerry Ryan David , Jhajj Gaganpreet , Zhang Xiaokun , Lin Fuhua Oscar
Published: October 2024

This chapter presents a novel GenAI tool, called PBL Support Chatbot, designed to support project-based learning (PBL) by integrating retrieval-augmented generation (RAG) and knowledge graphs (KGs). The aim is to address common challenges in PBL, such as project complexity and curriculum alignment. The tool provides students with real-time, adaptive support through a chatbot that assists in navigating PBL tasks. To illustrate its application, the authors introduce a scenario involving an introductory computer programming course where students develop a text-based adventure game. By offering personalized guidance, immediate feedback, and accurate answers to student inquiries, the tool aims to enhance critical thinking, learning outcomes, knowledge application, and student engagement in PBL environments. The initial prototype demonstrates the potential to improve the PBL learning experience. This underscores the capability of using RAG to create a dynamic, interactive learning environment that aligns with students' individual learning paths and educational goals.
Constructing Human Service Learning in the AI Digital Sphere

Published: October 2024

Service learning, a critical pedagogy combining community service with academic goals, fosters civic engagement, practical skill development, and social responsibility. This chapter explores how integrating Gen AI can enhance project-based service learning to address real-world social challenges in higher education (HE). Despite its rapid growth in HE, Gen AI still faces limitations, particularly the lack of a human-centred design method that reflects real-world contexts and the risk of oversimplifying complex tasks, leading to a more automated, less humanised learning process. The DEEP method, structured upon four co-designing phases—direction, education, event, and project—offers a hybrid solution, creating an adaptable and scalable framework for constructing a project with Gen AI for co-designed, social, and personalised learning. The chapter also illustrates the LivePBL project, piloted to train pre-service teachers in China, demonstrating how the method can effectively integrate Gen AI with hands-on co-design to enhance the learning environment and societal exchange.
Estudo da influência do uso de resíduos de marmoraria no desempenho de concretos

Published: October 2024

A construção civil é um dos setores que mais contribui para o desenvolvimento econômico e social do país, no entanto, é responsável por um grande impacto ambiental, em especial na geração de resíduos. Além dos resíduos gerados a partir da realização das atividades ligadas diretamente à construção civil, há os resíduos provenientes do beneficiamento de materiais empregados no setor, como por exemplo, as rochas ornamentais. Por este motivo, é indispensável buscar alternativas e novas tecnologias de reaproveitamento desses resíduos, a fim de minimizar o consumo de recursos naturais e a disposição incorreta desses materiais na natureza. O trabalho buscou incorporar os resíduos de marmoraria no concreto, material com grande demanda de uso, e realizar um comparativo entre as propriedades do concreto produzido sem a incorporação do resíduo e as dos concretos com adição e substituição, nos teores de 5%, 7,5%, 10% em relação ao cimento. Avaliando os resultados obtidos, considerando as propriedades físicas e mecânicas dos concretos com a incorporação, verificou-se um melhor desempenho nas amostras com teor de 5% de adição em relação à massa de cimento, uma vez que os valores de resistência à compressão aos 28 dias foram ligeiramente menores que os do concreto de referência e a porosidade apresentou resultados de absorção de água e índice de vazios menores que o do concreto de referência, o que pode propiciar maior durabilidade ao material. Dessa forma, o trabalho apresentou resultados interessantes que viabilizam a incorporação de resíduo de marmoraria na produção de concretos, bem como novos estudos sobre o tema.

Personal and In-store Factors on Impulse Buying Behavior: Moderating Role of Generation
Authors: Perera A. K. D. N. , Nishadi G. P. K.
Published: October 2024

The Sri Lankan supermarket industry has experienced significant growth and transformation in recent decades, driven by urbanization, changing lifestyles, and an expanding middle class. Additionally, understanding the factors that contribute to impulsive purchases in a supermarket setting is crucial due to the scarcity of existing findings relevant to the field. This study aimed to test the factors influencing impulse buying behaviour in the Sri Lankan retail sector, with a particular focus on personal factors, in-store factors, and the moderating role of generation. Primary data were collected from 384 customers of Keels supermarket in Sri Lanka based on a convenience sampling method through a self-administered questionnaire. The results showed that individual characteristics including time availability, family influence, and financial availability have a significant impact on impulsive buying behaviour. In a similar vein, it was discovered that in-store elements like music, friendly staff, lighting, and sales promotions significantly influenced customers' impulsive purchasing decisions. Paint colour and retail atmosphere, however, had little effect on impulsive purchasing. Moreover, generation emerged as a significant moderator in these relationships, with different generations exhibiting varying responses to personal and in-store factors. Generation Z (12-29 years), Generation Y (30-43 years), and Generation X (44-58 years) displayed distinct patterns in their propensity for impulse buying, highlighting the importance of considering generational differences in marketing strategies. The practical implications of these findings are substantial for marketers and retailers operating in the Sri Lankan retail market. By understanding the factors driving impulse buying behaviour and how Generation moderates these relationships, retailers can tailor their marketing efforts and optimize their store environments to better cater to the preferences of different demographic segments.
