Authors: Sistuk Volodymyr
Published: December 2024

Problem. Mining and processing plants, along with a metallurgical plant, serve as the primary destinations and origins for work trips in Kryvyi Rih. The transport and pedestrian accessibility of public transport (PT) and its stops in these industrial areas are crucial, particularly given the city's linear planning structure characterized by scattered mining districts and economic activities concentrated along the main transport axis. Despite the extensive body of literature focused on PT accessibility, there has yet to be a study specifically examining the accessibility of PT for mining districts within a city that features a linear and dispersed planning structure. Goal. The aim of this study is to perform a comprehensive analysis of public transport accessibility (PTA) as an indicator of transport supply for the mining districts (zones) within the city’s linearly dispersed urban structure. Methodology. The methodology for this comprehensive analysis of PTA relies on transport modeling using PTV Visum software, along with the collection of baseline data to evaluate shifts in transport demand in Kryvyi Rih from 2021 to 2024. Five zones with the highest job concentrations, as defined by Ukrainian Classification of Economic Activities B, were identified. PTA indicators were calculated for both the zones and their serving stops, with travel time set as the primary accessibility criterion, analysed through a comparison of accessibility isochrones. Given the large spatial extent of the mining zones, pedestrian accessibility to these stops is proposed to be evaluated based on the length of PT connectors and the area of each zone within the model. Originality. The study introduces, for the first time, the "limited accessibility of stops" indicator, defined as the ratio of the length of PT connectors to the area of the corresponding zones within the model. This indicator aims to account for the pedestrian accessibility of mining district's stops. Practical value. Proposed practical measures aim to enhance PT efficiency in terms of accessibility within a city characterized by a linearly dispersed planning structure.

Authors: Huy Vu Quoc
Published: December 2024

Electrical efficiency of photovoltaic (PV) solar cell is reduced significantly with the increase of its temperature. Cooling down the PV solar cell is essential to maintain the electrical performance and lifetime of the PV module. In the present study, cooling of PV module using a paraffin-based phase change material (PCM) in hot climate of Vietnam is investigated. Thermal modelling is first validated against experimental data reported in literature and then transient thermal simulations are carried out for a duration of 24 hours to assess the effect of PCM itself and PCM with internal fins. Results indicate that the peak temperature of the PV cell can be reduced by 4.3 K thanks to the PV-PCM system with PCM of 40 mm thickness and up to 10 K if the system is integrated with two cooling internal fins.

Authors: Deleon John , Hatherleigh Charlotte , Cumberbatch Ambrose , Ashworth Jonathan , Heathcote Lachlan
Published: December 2024

The evolving complexity of cybersecurity threats has driven the need for more advanced detection systems capable of addressing increasingly sophisticated ransomware attacks. This study introduces a novel framework built on contextual signature extraction, which analyzes dynamic system interactions to identify ransomware-specific behaviors before the encryption process begins. The framework’s modular architecture enables real-time processing, scalable deployment, and low-latency anomaly detection, making it highly adaptable to diverse operational environments. Unlike traditional signature-based and behavioral approaches, which often fail against polymorphic or obfuscated ransomware variants, the proposed system integrates advanced anomaly profiling and lightweight neural networks to achieve a balance between detection accuracy and computational efficiency. The evaluation demonstrates high accuracy and minimal false-positive rates across various ransomware families, including LockBit, BlackCat, and Hive, even under demanding workloads. Its ability to detect malicious activities at an early stage significantly reduces the risk of encryption-related data loss, offering a substantial improvement over existing techniques. Adversarial testing highlights the system’s robustness against evasion strategies, though further enhancements are needed to address extreme obfuscation and fileless attacks. The modular design ensures scalability and efficient resource utilization, making the framework suitable for both enterprise-level systems and resource-constrained environments. Insights into anomalous network behaviors and memory-resident attacks further demonstrate the versatility of the proposed approach. By combining real-time contextual analysis with adaptive anomaly detection, the framework establishes a new benchmark for ransomware detection and mitigation. The results highlight its potential to deliver robust and practical cybersecurity solutions, addressing both current and emerging challenges with precision and efficiency.
PSYCHEDELIC SCIENCE: Drugs Are the Same: Legal or Illegal. Stimulation as a Necessity: A Reinterpretation of 'Drugs' in Contemporary Society
Authors: Carrasco-Jiménez Edison
Published: December 2024

This article presents a critical reinterpretation of the concept of "drugs" in contemporary society, challenging the traditional categorization that separates legal substances from illegal ones. Through a multidisciplinary analysis incorporating psychology, neuroscience, and sociology, it argues that drugs, regardless of their legal status, are merely stimulatory substances that serve as nutrients for both the mind and the body. The need for stimulation is framed as a fundamental human response to social discomfort, as described by Freud in The Malaise of Civilization. From this perspective, both legal drugs (such as coffee and tea) and illegal ones (such as psychedelics) serve the same basic function: alleviating the anxiety inherent in social and cultural tensions. The concept of soma in Aldous Huxley's Brave New World is incorporated as a critique of how consumer societies seek artificial pleasures to mitigate suffering. Finally, the article offers a comparative analysis of different drugs and their effects on the human psyche, suggesting that the future of psychedelic drug legalization should be considered not only from a medical standpoint but also from cultural and philosophical perspectives. This study offers new insights into the role of drugs in mental health and social wellbeing.
Misinformation among Migrants: Evidence from Mexico and Colombia
Authors: Bandiera Antonella , Rojas Daniel
Published: December 2024

This paper examines the effectiveness of media literacy interventions in combating misinformation among in-transit migrants in Mexico and Colombia. We conducted experiments to study whether an established strategy for fighting misinformation works for this understudied yet particularly vulnerable population. We evaluate the effect of digital media literacy tips on migrants' ability to identify false information and their intentions to share migration-related content. We find that these interventions can effectively decrease migrants' intentions to share misleading migration-related information, with a significantly larger reduction observed for false content than accurate information. We also find that prompting participants to think about accuracy can unintentionally obscure sharing intent by acting as a nudge. Additionally, the interventions decreased trust in social media as an information source while maintaining trust in official sources. The findings suggest that incorporating digital literacy tips into official websites could be a cost-effective strategy to reduce misinformation circulation among migrant populations.
Reducing Appointment Delays: The Impact of Standardized EHR Usage on Physician Timeliness
Authors: Celik Umit , Rath Sandeep , Staats Bradley
Published: December 2024

Problem definition: Wait times in appointment systems, defined as the duration between scheduled appointment times and the start of the appointment, significantly impact customer satisfaction and serve as a critical measure of service quality. Task standardization is a crucial operational strategy to reduce service time and, consequently, service provider delay for subsequent appointments. While prior research has demonstrated the effectiveness of task standardization in reducing wait times, a nuanced understanding of task standardization's short-term and long-term effects is crucial for improving service quality. Without this insight, standardization interventions may address immediate wait time issues but could inadvertently create new challenges over time, such as affecting follow-up appointments. Methodology/Results: To explore task standardization's short-term and long-term effects, we focus on the specific case of Electronic Health Record (EHR) documentation. Using a dataset of over 120,000 appointments from 57 physicians at a major academic medical center, we investigate how the standardization of EHR documentation tasks affects appointment delays. Our unit of analysis is the individual appointment. We define our treatment variable as the Standardization Ratio, which measures the level of standardization in each appointment. It is calculated as the time spent using EHR tools like SmartPhrases, as a fraction of the total work done. Our approach enables us to assess both the immediate impact of standardization on appointment durations and its longer-term effects, such as the length of follow-up appointments. We employ double machine learning as our primary method to address potential endogeneity in SmartPhrase usage, given its ability to handle continuous treatments and high-dimensional covariates while providing robust and unbiased estimates. To validate our findings further, we also use nearest-neighbor matching. Our model results are consistent between the two estimation procedures. Our findings indicate that a 10% increase in the proportion of appointment time dedicated to standardization tools reduces appointment delays by 0.4%, likely due to a 6.8% decrease in the proportion of time physicians spend in the patient room. Managerial implications: This demonstrates that, in the short term, task standardization can effectively reduce delays. However, this shift also leads to a 78-word increase in clinical documentation and a 0.25% rise in the in-room time ratio for future follow-up appointments, suggesting potential long-term trade-offs in clinical efficiency. This highlights a trade-off between short-term efficiency and long-term task burdens. While task standardization is known to improve timeliness and reduce wait times, our results emphasize the need for a balanced approach. Standardization tools streamline processes and improve immediate efficiency but may increase future workload and prolong future interactions.

Published: December 2024

Food addiction (FA) and posttraumatic stress disorder (PTSD) are each associated with obesity and adverse psychological outcomes. The goal of this study was to generate symptom profiles based on varying levels of FA and PTSD symptoms. We hypothesized four profiles: PTSD+FA; PTSD; FA; healthy. In a general Polish population (N=2245), scores on PTSD Checklist for DSM-5 (PCL-5), Lifetime Events Checklist (LEC), and Yale FA Scale (YFAS) were used as indicators in the latent profile analysis. Gender and Negative Urgency (SUPPS-P) were used as predictors of profile membership. Scores on Emotional Eating (DEBQ), AUDIT, Depression (DASS-21), binge eating presence were used as validators. The sample was divided into two subsamples to conduct a robustness check. In both samples (n1=1133; n2=1132), a three-profile solution emerged with high PCL-5, LEC, YFAS (PTSD+FA); high PCL-5 and LEC, low YFAS (PTSD profile); and low PCL-5, LEC, YFAS (healthy). No FA profile emerged. Predictors and validators meaningfully differentiated profiles. Findings indicate that FA is closely related to PTSD symptoms. PTSD+FA profile had the highest BMI, dysregulated eating, and problematic alcohol use, indicating a potential “reward deficiency profile” at highest risk for obesity. PTSD and dysregulated eating should be assessed in tandem.

Authors: Lun Ning , Chen Huaxing , Liu Ye , Zhang Jiangmin , He Yanhua , Wang Dong
Published: December 2024

Semantic boundary transference introduces a novel mechanism for enhancing the contextual adaptability and semantic coherence of computational language systems. The proposed framework incorporates a gradient-based approach to dynamically encode and transfer semantic boundaries, addressing limitations in managing transitions across complex linguistic contexts. Through the integration of advanced optimization techniques and regularization strategies, the methodology achieves robust performance while mitigating overfitting and maintaining computational efficiency. Empirical evaluations reveal significant improvements in contextual accuracy, semantic alignment, and domain-specific adaptability, particularly in tasks requiring complex linguistic comprehension. The ability to maintain stable token embeddings across diverse tasks demonstrates the framework's theoretical robustness and practical applicability. Scalability was validated through experiments involving varying sequence lengths, demonstrating the framework's effectiveness in handling extensive textual inputs without compromising efficiency. Cross-lingual evaluations highlighted its capability to generalize semantic transference across languages, with notable resilience in low-resource settings. Error analysis provided insights into the controlled adaptability of the semantic gradient mechanism, ensuring minimal deviation from ground truth representations. The integration of noise-resistant techniques further enhanced model robustness under adversarial conditions, showcasing the framework's versatility. Domain-specific knowledge retention experiments revealed consistent alignment with task requirements, especially in structured and specialized domains. The findings collectively suggest that semantic boundary transference offers a transformative approach to addressing long-standing challenges in language model adaptability, contributing valuable insights to computational linguistics and artificial intelligence research.
Translating Well-being Values into Design Features of Social Media Platforms: A Value Sensitive Design approach
Authors: Figueroa Caroline , Marin Lavinia , de Reuver Mark , Jaff Mani
Published: December 2024

Mental health problems are on the rise among adolescents and young adults, and growing evidence points to social media platforms as a potential influence. Design decisions made by platform developers shape the digital environments and online daily interactions and may crucially impact users’ mental well-being. However, it is challenging to translate abstract values such as “well-being” or “mental health” into concrete norms and design features in the context of social media. In this study, we explore the potential of using a value sensitive design approach towards redesigning a social media environment that promotes mental well-being. Using the three iterative phases of the approach, we interviewed social media experts and held a focus group with adolescent users. We used thematic analysis to analyze the results and created a values hierarchy that translates abstract values related to well-being into norms and concrete design requirements. This analysis revealed 13 values at stake related to mental wellbeing in the context of social media. Results reveal that mental well-being is negatively impacted by a lack of fulfilling values such as authenticity and connection, personalization and autonomy, and control and autonomy. These experiences are associated with design features such as notifications, algorithmic recommendations, likes, comments, and news feeds. The findings show the pivotal role of design decisions made by social media platforms developers in shaping user well-being. We show how a value-sensitive design approach, in which young users themselves and other stakeholders are involved, can enable the integration of key values into technological development.
Overcoming Boundary-Layer Separation with Distributed Propulsion
Authors: Suppes Adam Bradford , Suppes Galen
Published: December 2024

Strategically located propulsors are able to create constructive interference on aircraft; increasing lift, lift-drag ratios (L/D), and resilience to boundary layer separation.  Computational fluid dynamic (CFD) studies teach toward an optimal configuration with a near-zero upper-surface pitch in front of a trailing section propulsor followed by a trailing taper with 20° to 45° surface pitch from the propulsor to a trailing edge near the bottom of the lifting body (“Lift Span Tech”).  Applications benefiting from Lift Span Tech range from box trucks to high-speed intercontinental transit.  With initial propulsor power mitigating boundary layer separation, Lift Span Tech provides a high gain:loss, where the gain is in reduced drag and loss is reduced thrust from the propulsor.  Performance may be augmented with ground effect further improving L/D efficiency.  This study evaluates the sensitivity of performance to different CFD turbulence models and trailing taper pitches.  While today’s commercial approaches can reduce truck drag by about 34% with no impact on wheel friction, new Lift Span Tech is able to reduce drag by up to 84% and wheel friction by up to 90%.  The technology enables designs to allow direct solar power to fully replace liquid fuels in a wide range of vehicles.

Throwing good effort after bad: Evidence for a sunk-cost effect in cognitive effort-based decision-making
Authors: Bogdanov Mario , Devine Sean , Fu Ziqi , Wang Echo , Otto A. Ross
Published: December 2024

The sunk-cost effect, an influential decision-making bias elicited by the consideration of past, irrecoverable resource investments toward a choice option, is well-documented for economic decisions. Contrary, evidence for sunk-cost effects for non-monetary costs, such as cognitive effort, has been mixed. Here, we present findings from two experiments (in-person study: N=36; online study: N=89), in which healthy participants performed an effort investment task designed to assess the impact of past effort exertion on current choices about continuing or abandoning a course of action. Across both experiments, we found that prior effort investment substantially increased participants’ willingness to invest further resources (i.e., to exert additional effort). These findings provide compelling evidence for the existence of an effort-based sunk-cost effect. Further, they highlight the importance of previous effort investments for influencing present choice behavior, indicating the need to refine contemporary cost-benefit models of effort to account for past effort exertion.
Excavating the past and (re)finding myself: Why and in what ways do veterans and providers believe archaeology supports mental health and wellbeing?
Authors: Burnell Karen , Everill Paul
Published: December 2024

Participation in heritage and archaeology is increasingly offered in the community to support mental health and wellbeing, often to groups experiencing mental health challenges. One such group are military veterans, who experience higher rates of mental health challenges than the general population, including trauma and loss, and lower help-seeking behaviour. Since 2011 archaeological projects have been offered to veterans to support transition and mental health and wellbeing. For veterans, and other groups, provision has become increasingly framed as an intervention, with evaluation focused on mental health and wellbeing outcomes. However, there is little understanding of why and how archaeology has a positive impact. Adopting an interpretative qualitative approach, we interviewed five UK veterans and four providers of UK projects about their experiences of archaeology. Through thematic analysis, three themes were created 1) connection and belonging, 2) authenticity and purpose, and 3) meaning-making through the past. Taking an interdisciplinary approach, this study provides further insight into the ways in which archaeology may support psychological wellbeing, but perhaps not mental health, with implications for further research and practice in this area, particularly concerning the powerful opportunities for meaning-making.
The perfectionistic model of pro-environmental behaviour: Using perfectionism and dichotomous thinking to explain why people avoid difficult pro-environmental behaviours
Authors: Greene Danyelle , Egan Sarah Jane
Published: December 2024

Perfectionism is linked to elevated all-or-nothing (dichotomous) thinking, reduced self-evaluations (e.g., self-compassion, self-efficacy), and behavioural avoidance. This paper reviews the clinical model of perfectionism and the literature on the connections between perfectionism, self-related constructs such as self-compassion and self-efficacy, and pro-environmental behaviour. It introduces the ‘perfectionistic model of pro-environmental behaviour.’ In an initial test of the model, we explore the associations between perfectionism, dichotomous thinking, self-evaluative constructs and the stated frequency of different types of pro-environmental behaviours. The sample comprised of 344 participants (Mean age = 43.66; SD = 13.01). Our findings reveal that perfectionistic concerns (self-criticism about making mistakes) and perfectionistic strivings (setting high personal standards) exert opposing effects on the reported frequency of difficult pro-environmental behaviours. Specifically, perfectionistic concerns are associated with decreased frequency, while perfectionistic strivings are linked to increased frequency of difficult pro-environmental behaviours. Dichotomous thinking negatively correlates with the frequency of difficult pro-environmental behaviour. Both perfectionistic concerns and strivings indirectly influence pro-environmental behaviour frequency through dichotomous thinking. This study suggests that future longitudinal research should examine if heightened perfectionism leads to increased dichotomous thinking, resulting in decreased frequency of pro-environmental behaviour over time. Given the negative association between dichotomous thinking and the frequency of difficult pro-environmental behaviours, future research could explore whether continuous framing of pro-environmental behaviour yields better overall improvement compared to binary framing in an experimental study.

In this research paper I have thoroughly described about the topic “Evaluating the Impact of Open Book Exams on Secondary School Student Performance in Panipat District.” The purpose of this research is to determine how open book examinations affected the academic performance of Panipat District secondary school students. Research tries to evaluate the usefulness of this assessment approach by comparing average results from conventional tests with open book exams, and by examining subject-specific improvements. From 65.4% on conventional examinations to 72.8% on open book exams, with particular gains in Science and Mathematics, according to data gathered from 200 students. Additional qualitative evidence from both students and instructors points to less test anxiety and more involvement, lending credence to these results. Based on the findings, it seems that open book examinations provide a more conducive learning environment by allowing students to better grasp and apply what they have learned. This study suggests that open book examinations might be a good addition to secondary school evaluations, but more research is required to determine the long-term effects and problems with implementing them.
