EMGLight: A Joint Optimization Method for Emergency Signal Priority
and Recovery Based on DDPG
Authors: Jiang Xin , Zhang Jian , Qian Yu
Published: February 2025

The rapid response of emergency vehicles (EVs) is crucial in safeguarding lives
and property during emergencies. However, conventional traffic signal control
methods for EV priority often disrupt normal traffic flow, leading to
significant delays for general vehicles and decreased overall traffic
efficiency. This study proposes EMGLight, a novel traffic signal control
framework based on Deep Deterministic Policy Gradient (DDPG), to optimize EV
priority and signal recovery jointly. By leveraging DDPG's ability to handle
continuous action spaces, EMGLight achieves fine-grained control over traffic
signals, adapting dynamically to real-time traffic conditions. Additionally, a
dynamic reward mechanism is introduced, balancing EV priority with the recovery
needs of general traffic. Simulation results demonstrate that EMGLight
outperforms traditional fixed-cycle and greedy preemption methods, significantly
reducing EV travel time while minimizing the adverse impact on general traffic
flow. This approach highlights the potential of reinforcement learning to
enhance emergency urban traffic resilience.
Spatio-Temporal Traffic Forecasting with Uncertainty Quantification
via Bayesian Graph Convolution
Authors: Li Linfeng , Lin Limeng
Published: February 2025

Traffic prediction plays an important role in urban traffic management and signal
control optimization. As research in this area advances, traffic prediction has
become increasingly accurate. However, the complexity of the traffic system
makes the quantification of uncertainty particularly important, as it is
influenced by various factors such as weather changes, emergencies and road
construction, which lead to the fluctuation and uncertainty of the traffic
state. Although some progress has been made in traffic uncertainty
quantification, most methods remain primarily focused on individual traffic
observation points, with little exploration of the complex spatiotemporal
dependencies at the road network level. In light of this situation, this paper
proposes a spatiotemporal traffic prediction model based on Bayesian graph
convolutional network, which can effectively capture the spatiotemporal
dependence in traffic data, facilitating accurate predictions and comprehensive
uncertainty quantification. Through the design of a mixed loss function, the
model achieves a good balance between the accuracy of point estimation and the
effectiveness of uncertainty quantification. The experimental results show that
the proposed model has high efficiency and stability in dealing with complex
traffic conditions, providing new insights for research in traffic prediction
and uncertainty quantification at the road network level.
Uncertainty Quantification for Predicting Low-Temperature Crack
Resistance of Asphalt Mixture Base on Bayesian Neural Network
Authors: Song Ziyu , Ni Fujian , Huang Jiaqi , Jiang Jiwang
Published: February 2025

Developing models for predicting the low-temperature cracking resistance of
asphalt mixtures is a complex process with a wide variety and complex influence
mechanisms of variables, leading to higher uncertainty in the prediction
results. Several models have been developed in this regard. This study developed
a Bayesian neural network (BNN) model for predicting the fracture energy of
low-temperature semi-circular bending (SCB) tests based on pavement condition
measurements, traffic, climate, and basic parameters of the material. The model
was trained and evaluated using low-temperature SCB test data from in-situ
pavement core samples, and the results showed that the coefficient of
determination (R2) of the BNN model was greater than 0.8 for both the training
and testing sets. The variable importance scores showed that the decrease of
transverse crack rating index (TCEI) and gradation were the most important
factor affecting low-temperature fracture energy and that the ambient
temperature was relatively least important. The uncertainty of the BNN model
variables was quantified using epistemic uncertainty and aleatoric uncertainty.
The results of the uncertainty analyses showed that the epistemic uncertainty
was less than or equal to the aleatoric uncertainty for most of the variables
used in this study, which indicated that the uncertainty caused by the model
parameters was less than that caused by the noise in the original data, that
corroborated the reliability of the BNN model used in this study.
Research on Triple-Frequency Dual-Ionosphere-Free Combination PPP
Based on PPP-B2b Service
Authors: Xu Dawei , Gao Chengfa , Xu Zhenhao , Zhan Kaidi , Guo Songlin
Published: February 2025

The recent public release of the PPP-B2b service, along with advancements in
multi-frequency and multi-GNSS systems, has opened up significant new
opportunities for the development of Precise Point Positioning (PPP) technology.
Utilizing the precise orbit and clock corrections provided by PPP-B2b and the
increasing availability of multi-frequency signals, this paper introduces a
novel tri-frequency, dual ionosphere-free PPP model based on PPP-B2b services.
The model is designed with twelve unique tri-frequency combinations, tailored to
various frequency choices, combination methodologies, and single/dual GNSS
systems. Results from static positioning experiments indicate that the BDS-only
tri-frequency dual ionosphere-free model offers substantial improvements over
traditional models. Specifically, it achieves approximately a 25% increase in
vertical accuracy and reduces convergence time by around 30% when compared to
the BDS-only tri-frequency undifferenced uncombined model. This demonstrates the
model's potential to enhance performance under static conditions. For dynamic
positioning, the model proves equally effective. The four BDS-only tri-frequency
dual ionosphere-free combinations show accuracy in the E and U directions
comparable to that of the BDS-only four-frequency undifferenced uncombined
model. However, in the N direction, the tri-frequency dual ionosphere-free
combinations reach an average accuracy of 0.010m, which represents an
approximate 40% improvement over the 0.017m achieved by the four-frequency
undifferenced uncombined model. Additionally, these combinations reduce
convergence time by about 30%.When GPS is incorporated, the dual-system
tri-frequency combination offers even more benefits. Both in dynamic and static
scenarios, the dual-system approach improves convergence time by 20% to 40%
compared to single-system positioning, while also achieving slightly higher
positioning accuracy. These findings underscore the effectiveness of the PPP-B2b
service in optimizing PPP applications for both static and dynamic use
cases.
Research on SINS/GNSS Integrated Positioning for Highway
Vehicles
Authors: Zhang Hongbin , Wen Chengju , Liu Zhe , Lin Chen
Published: February 2025

This study investigates the application of integrated positioning based on SINS
(Strapdown Inertial Navigation System) and GNSS (Global Navigation Satellite
System) for highway vehicle navigation. While GNSS offers high-precision outdoor
positioning, it is susceptible to signal obstructions, whereas SINS enables
autonomous positioning without external signals but accumulates drift errors
over time. To enhance positioning accuracy, this study employs three nonlinear
filters—Extended Kalman Filter (EKF), Unscented Kalman Filter (UKF), and
Cubature Kalman Filter (CKF)—for multi-source data fusion. Experimental results
demonstrate that EKF, UKF, and CKF achieve faster convergence, higher stability,
and smoother error curves when handling nonlinear problems. Through simulation
experiments and field measurements, the strengths of each algorithm are
validated across different metrics and directions. Considering sensor
limitations and implementation complexity, EKF outperforms other algorithms in
scenarios with limited sensors. The findings of this study provide a foundation
for improving vehicle navigation accuracy in complex environments.
A Traffic Conflict Risk Assessment Model for Highway Construction
Zones Based on Trajectory Data
Authors: Zhang Yuwen , Guo Xiucheng , Ma Yuheng
Published: February 2025

Highway construction zones present substantial safety challenges due to their
dynamic and unpredictable traffic conditions. With the rising number of highway
projects, limited accident data during brief construction phases underscores the
need for alternative safety evaluation methods, such as traffic conflict
analysis. This study addresses vehicular safety issues within the Kunshan
section of the Shanghai-Nanjing Expressway, focusing on conflict risk assessment
through a spatio-temporal analysis of a construction zone. Using drone-captured
video, vehicle trajectories were extracted to derive key operational indicators,
including speed and acceleration, providing a spatio-temporal foundation for
analyzing traffic flow and conflict dynamics. A novel **Comprehensive Collision
Risk Index (CCRI)** was introduced, integrating Time-to-Distance-to-Collision
(TDTC) and Enhanced Time-to-Collision (ETTC) metrics to enable a
multidimensional assessment of conflict risk. The CCRI captures both
longitudinal and lateral risks across varied traffic scenarios, offering a
robust indicator of conflict distribution, severity, and spatial characteristics
within the zone. Conflicts with CCRI values exceeding 20 seconds are considered
non-critical, indicating minimal risk. To predict conflict severity, three
machine learning models—Logistic Regression, Random Forest, and Multi-Layer
Perceptron (MLP) Neural Network—were developed and compared. The Random Forest
and MLP models demonstrated superior predictive accuracy and stability, with MLP
achieving balanced performance across both severe and general conflict
categories. Additionally, spatio-temporal analysis of CCRI values identified
transition zones as lower-risk areas, with factors such as speed and distance
differentials emerging as primary contributors to conflict severity. This
research advances traffic safety evaluation in construction zones by introducing
CCRI as a comprehensive, spatio-temporal risk metric and leveraging machine
learning for precise conflict severity prediction. The findings provide valuable
insights for developing targeted safety interventions and adaptive traffic
management strategies, offering crucial support for transportation engineers,
safety practitioners, and policymakers in enhancing safety within dynamic,
high-risk construction environments.
“Ilegant Natives of Erin”: The Irish in Cheltenham 1801-1861
Authors:   , Clifford Peter
Published: February 2025

A local study of the Irish in Cheltenham was conducted along the lines of the “mixed methods” paradigm suggested by Swift. The Irish-born population, as recorded in the census of 1841, 1851 and 1861, was subjected to a biographical survey, and census data were obtained (from I-CeM) in order to allow the characteristics of the Irish in Cheltenham to be analysed statistically in the context of the wider demographic profile of the town. Topics investigated quantitatively include: population growth, migration levels, geographical distribution, occupations, socio-economic diversity, permanence/transience of residency, integration or segregation, and origins in Ireland. The lived experiences of these people were then investigated further from a variety of thematic perspectives. Subjects considered qualitatively include: housing, community relations, alcohol and disorder, social mobility, religion, politics, and education. Incidents of Anti-Catholic sentiment and violence, enflamed by Francis Close’s rabid evangelical rhetoric, are examined. The Great Famine and its effects, reaching even as far as Cheltenham, are discussed, as well as the response of the local Poor Law Guardians to the problem. An interesting conundrum relating to apparent, but unexplained, connections between members of the Cheltenham working-class Irish community and two of Feargus O’Connor’s Chartist colonies is explored. Two very different groups of Irish people in Cheltenham were distinguished, from diametrically opposing ends of the socio-economic scale, one of extremely high status, the other of particularly low status. Cheltenham was identified as being highly unusual, possibly unique, in having roughly equal numbers of Irish-born people from these diverse social classes living in close proximity to one another. The characteristics of the low-status Irish were found to be very similar to those of working-class Irish people in other British cities, and, like the Irish in other places in South Wales and South-west England, they were predominantly from County Cork. The high-status Cheltenham Irish, who included numerous absentee landlords, on the other hand, hailed mostly from Dublin, Ulster and other parts of Ireland, and were more closely aligned with their British-born neighbours from similar backgrounds than with their working-class compatriots.
The consumption motivation of Vietnamese Generation Z consumers: An exploratory study of branded sports footwear
Authors:   , Dinh Khanh Phuong
Published: February 2025

Purpose/research questions: This research aims to understand Vietnamese Generation Z
consumers’ motivation to consume branded sports footwear. It explores individuals’ relationships
with brands during their customer journey and the purchasing characteristics of Vietnamese
Generation Z consumers when acquiring branded sports footwear from a business and academic
perspective.
Design/methodology/approach: The study employs an inductive, interpretivist approach,
involving twenty-five branded sports footwear consumers aged 18-25 years from Hanoi. Semistructured
interviews, conducted in Vietnamese, were used to explore participants’ experiences
with branded sports footwear. The interviews were analyzed using content analysis, and the
findings were then translated into English to preserve their meaning and nuances.
Results: During their customer journeys, Vietnamese Generation Z branded sports footwear
consumers are motivated by various attributes, including self-identity and hedonistic desires, social
responsibility, quality expectations and past experience, peer pressure, family and friends, and
online sources, including social media, online reviews and external virtual influencers. Ultimately,
the study revealed that the acculturation behaviour and the link between ethnocentric and
xenocentric characteristics of Vietnamese Generation Z consumers are fundamental, highlighting
the unique and distinctive purchasing behaviour experienced when these individuals buy branded
sports footwear.
Originality/value: Several theoretical and methodological contributions are made. Firstly, the
study provides an in-depth understanding of Generation Z’s consumption motives through a
Vietnamese and branded consumer lens. Secondly, the findings extend Hamilton et al.’s (2021)
customer journey model by adding a quality attribute, brand trust and brand respect, and finally the
inclusion of acculturation behaviour which spans across the model. Finally, this study adopts a
qualitative approach to explore further the complex nature of their consumption and purchasing
behaviour.
Practical implications: Marketers and manufacturers should prioritize the importance of quality
development in the manufacturing process and understand the unique acculturation characteristics
of Vietnamese Generation Z branded sports footwear consumers. This includes the demand for
localized and personalized products with a blend of self-identity, cultural heritage, and social
responsibility when manufacturing and marketing these branded items.
Future research: Recommendations for further research are offered, including the extension of
this study to other contexts.
Do we Blame Victims? A Critical Analysis of Victim Blaming Discourse found in Defensive Narratives of Intimate Partner Femicide Cases
Authors:   , Matthews Erica
Published: February 2025

The aim of this research was to explore and establish the use and nature of victim blaming discourses in defensive narratives within intimate partner femicide (IPF) cases where the victim is female, and the perpetrator is male. The research consisted of three stages. The first stage reviewed previous literature and studies about victim blaming themes and narratives found in IPF cases. The second stage was data collection of two mediums, collecting 120 media articles and 30 domestic homicide reviews (DHRs) reporting cases of IPF. Finally, the third stage was concerned with analysis of the data collected, conducted using feminist analysis combined with Carrabine’s (2001) Foucauldian Discourse Analysis structure.

This research observed many victim blaming themes in the current data, namely Denial of Responsibility, Blaming the/Her Situation, Provocation, Naggers, Whores, Libbers, and Perfect Victim/Lack Thereof. Victim blaming is found to be a common linguistic tool reached for by authors of media articles and DHRs when reporting IPF cases, and it has a strong role in allowing defensive narratives to be perceived as believable and accepted. In contrast to previous literature however, in some cases analysed, victim blaming only became obvious when the connotations of the language and context were analysed, rather than victim blaming being overt and unequivocal.

This research has allowed for a contemporary framework of victim blaming to be produced, whereby previous and current literature and findings are clearly demonstrated and can be used as a foundation for understanding of victim blaming. A recommendation from this research is to expand the data collection to explore more avenues where victim blaming may be present, such as from observing live IPF court cases. This would help increase the understanding of how, where, and potentially why victim blaming appears to be unavoidable for IPF victims and can be used as a basis for training those reporting and working with IPF cases, so we can reflect the life of a victim in a non-blameful manner.
Legal Challenges of Humanizing Robots. A Study of the Responsibility and Autonomy of Robots Equipped with Artificial Intelligence
Authors: Shehta Mohamed F. , Ibrahem Usama M. , Khalifa Gamal S.
Published: February 2025

Recent decades have witnessed significant developments in smart robotics and other artificial intelligence technologies. Robots are no longer just machines that carry out specific commands; rather, thanks to artificial intelligence (AI) algorithms, they can interact with humans and make decisions independently. This is particularly true because the programming of these robots enables them to grow and learn from their own experiences. The enormous capabilities that robots were able to possess led them to replace humans in most places and professions, which gave rise to the term "humanization of the robot" to refer to human-like robots that can make decisions and interact socially in a way that mimics human behavior. However, the real problem with this development lies in two parts. This research aims to explore the legal implications surrounding the autonomy and accountability of AI-equipped robots, focusing on how existing laws can adapt to address issues of responsibility in human-robot interactions. First, this development presents both advantages and disadvantages. The robot that helps humans perform their tasks better can unpredictably transform at any moment into an undeterrable and unstoppable human-killing monster. The second issue is that international jurisprudence has yet to establish a legal framework that defines the legal nature of these robots and confines them to a specific set of controls and laws. It also obliges their makers, programmers, and owners to adhere to these controls. In addition to previous legislation, the theory of the “responsible human representative” must be applied, which stipulates that they legally bear civil, tort, and criminal liability for what their robots do.

Published: February 2025

Georgia USA organisations achieve success in crisis response by implementing ethical leadership principles. The success of modern organisations depends on ethical leadership because direct ethical decision-making links closely with organisational outcomes. , USA. The study concentrates on three fundamental aspects: ethical decision-making, transparency, and stakeholder engagement. Through ethical decision-making, leaders can predict all possible outcomes of their decisions to build an accountable organisation based on integrity. Organisations receive greater decision-making clarity through stakeholder involvement because employees, customers, suppliers, and residents contribute to building collective goals that increase resilience capabilities. The research implements quantitative and qualitative approaches to produce a complete view of ethical leadership roles during crisis management. The research foundation bases its work on total literature reviews that explore ethical leadership and resilience domains. Research on crisis-related organisational success delivers practical applications that clarify the theoretical ideas present throughout this dissertation. New fresh papers have uncovered requisite characteristics of the connection between leadership ethics and organisational resilience. As research shows, crisis management is secondary to ethical leadership because it is a peripheral approach to achieving unsustainable outcomes.

This study investigates the antimicrobial potential of Rosa damascena flower extract, with a focus on its antibacterial and antifungal properties. The primary objective was to assess the inhibitory activity of the ethanolic extract against a spectrum of bacterial and fungal pathogens. Using the agar disc diffusion method, the extract was evaluated at a concentration of 100 µg/ml against two Gram-positive bacteria (Bacillus subtilis, Staphylococcus aureus), one Gram-negative bacterium (Escherichia coli), and four fungal strains (Aspergillus fumigatus, Aspergillus niger, Candida albicans, and Monascus purpureus). The zones of inhibition produced by the extract were compared to those of standard antibiotics: ciprofloxacin for antibacterial activity and fluconazole for antifungal activity. The findings revealed significant antibacterial effects, particularly against Gram-positive bacteria, with clear zones of inhibition, suggesting that Rosa damascena harbors a diverse array of bioactive secondary metabolites, the extract demonstrated notable antifungal activity, with inhibition observed across several fungal strains. These results underscore the extract's promising antimicrobial potential, highlighting its efficacy as a source of bioactive compounds, the study suggests that Rosa damascena could serve as a valuable resource for the development of novel antimicrobial agents, particularly in light of increasing resistance to conventional antibiotics. Further investigation into the specific mechanisms of action, toxicity, and the isolation of active compounds is warranted to advance its potential as a therapeutic agent in the pharmaceutical industry. Additionally, exploring the synergistic effects with other natural compounds could enhance its therapeutic efficacy and broaden its applications in clinical settings.

Social advocacy plays a significant role in enhancing the protection and handling of minors who experience sexual abuse and violence. Collaboration between child protection agencies, non-governmental organizations, and the government in building advocacy networks is crucial for advocating for better policy changes and ensuring effective implementation. Despite some progress, challenges remain in this social advocacy process. Barriers such as insufficient resources, social stigma, and low public awareness need to be addressed. This study aims to investigate the social advocacy process regarding the handling of minors experiencing sexual abuse and violence. Through a qualitative approach, literature review, and interviews with relevant stakeholders, the research analyses advocacy efforts in addressing cases of sexual abuse and violence against children. Additionally, this study proposes recommendations for improvement, including enhancing public education, broader stakeholder training, and strengthening child protection policies. The advocacy process in handling minors involved in sexual abuse and violence requires a strong social advocacy effort. By strengthening the social advocacy process through education, policy reinforcement, training, victim support, and a robust advocacy network, we can improve protection and handling of these cases and give a voice to those who need support in cases of sexual abuse and violence against minors.

Introduction: There is considerable interest in understanding the physical demands of futsal players to achieve optimal performance.
Objective: This study aimed to investigate the effects of curcumin and piperine supplementation on the performance of futsal players after two consecutive intensive matches.
Methodology: A randomized, double-blinded, placebo-controlled design was used in this study. Sixteen amateur futsal players participated and were randomly assigned to two equal groups. The experimental group received curcumin 100 mg + piperine 5 mg, while the placebo group received 105 mg of microcrystalline cellulose. Two matches were played consecutively 24 hours apart (2 × 20 minutes). VO2max was assessed seven days before the first match, while internal load heart rate was evaluated during both matches. To examine players' recovery, CMJ and sprint performance were measured at baseline, 24 hours after the first match, and at 24, 48, and 72 hours after the second match.
Results: VO2max and heart rate were similar between both groups, indicating comparable fitness levels and internal load heart rate. Significant differences were found in CMJ (p<0.05) and sprint times (p<0.05) between the experimental and placebo groups at 24, 48, and 72 hours after the second match.
Discussion: The results suggest that curcumin and piperine supplementation effectively enhance recovery by reducing muscle fatigue and preserving neuromuscular performance after matches.
Conclusions: The combination of curcumin and piperine enhances recovery and helps maintain performance in futsal athletes with demanding competition schedules.

Introduction: This study was conducted to examine the quality of life and its sub-dimensions of university students according to their physical activity status and participation in sports for all federation (HIS) activities.
Methodology: Accordingly, 801 students (male=505, and female=296) from different universities in Turkey and Kazakhstan ) were included in the study. Quality of life levels and sub-dimensions (general health, physical health, psychological health, social relations, environmental relations) were analyzed. World Health Organization Quality of Life Scale (WHOQOL) was used to determine the quality of life of the participants.
Results: Accordingly, physical health status (t=2.422, p=.016), social relations (t=2.063, p=.039), environmental relations (t=3.759, p<.001), and WHOQOL results (t=3.175, p=.002) were significantly higher in men. In addition, as the participants' grade level increased, their general health status, psychological health, social relations, environmental relations, and WHOQOL scores generally increased (p<0.05). WHOQOL scores and sub-dimensions were significantly higher in those who practiced sports competitively and for recreational purposes (p<0.05). There was a significant difference in all parameters except physical health status in individuals participating in HIS activities (p<0.05).
Conclusions: As a result, it is thought that popularizing sports among university youth is an important factor for these individuals to have a healthy quality of life.

Introducción y objetivo: El entrenamiento con resistencia variable (ERV) es una metodología de entrenamiento utilizada en la mejora de la fuerza muscular, pero sus efectos sobre la funcionalidad en personas con trastornos musculoesqueléticos han sido poco investigados. Esta revisión sistemática tiene como objetivo evaluar los efectos del ERV en la funcionalidad de estas personas.
Metodología: Se realizó una búsqueda en cuatro bases de datos (EBSCO, Scopus, Web of Science, PubMed), resultando en 694 estudios, de los cuales se seleccionaron 7 para su análisis. Los estudios incluyeron pacientes con diferentes disfunciones musculoesqueléticas como dolor lumbar, osteoartritis, y prótesis de rodilla.
Resultados: Los resultados muestran que el ERV mejoró significativamente la fuerza en tres estudios, el dolor en cuatro estudios, y la funcionalidad general en todos los estudios evaluados. Además, se observaron mejoras en el equilibrio y la velocidad de la marcha. A pesar de los resultados prometedores, la heterogeneidad de los protocolos y las diferencias en las evaluaciones limitan la generalización de los hallazgos.
Conclusiones: Se concluye que el ERV puede ser una intervención efectiva para mejorar la funcionalidad en personas con trastornos musculoesqueléticos, pero se requieren estudios adicionales para confirmar su eficacia en distintos contextos.

Introduction: Electromyostimulation (EMS) training has become a popular method to improve muscle strength and speed up athletes' recovery, especially in the sport of volleyball. However, although many studies support the effectiveness of EMS in individual athletes, its application in volleyball sport, is still not widely researched. Objective: This study aimed to evaluate the effects of EMS on muscle recovery and specific performance in the sport of volleyball. Methodology: The research sought to identify potential benefits and challenges in integrating EMS into volleyball training programmes to maximise overall team performance. The research method involved a comprehensive literature review, with reference to articles published in databases such as PubMed and Scopus. The literature search followed PRISMA guidelines, and only articles relevant to the topic of EMS in volleyball sport were considered. Of the total 220 publications found, only five articles met all inclusion criteria and were further analysed. Results: The results showed that EMS can significantly improve muscle strength and accelerate recovery after intense training, especially in explosive movements such as jumping and change of direction.  Discussion: The study also showed that combining EMS with functional training can improve VO2max capacity, muscle strength and physical endurance. However, the application of EMS in the sport of volleyball requires customisation to ensure that it does not disrupt team dynamics and coordination. Conclusions: EMS has the potential to be an effective tool in improving athlete performance and muscle recovery in volleyball sports. However, further research is needed to understand how EMS can be optimally integrated into team training programmes without disrupting team balance. Future research should also evaluate the long-term impact of EMS on team athlete performance.
