This study delves into electrocoagulation for removing copper and cadmium from synthetic water, exploring both individual and binary removal. Employing the Box‒Behnken design method, the research fine-tuned process operating factors including current density (10 to 50 mA/cm2), starting pH (3 to 7), and metal ion concentration (100 to 300 ppm). Optimal conditions for single-element systems yielded 99.02% copper removal (pH value of 5.63, current density value of 50 Am-2, copper concentration 100 ppm) and 98.45% cadmium removal (pH 6.15, current density 50 A/m2, cadmium concentration 124 ppm). Findings underscored the substantial current density impact on removal efficiency, surpassing the effect of pH and metal ion concentration. Notably, the current played a more pivotal role in cadmium removal than in copper removal. A robust R2 analysis of variance (98.85% for Cu and 99.50% for Cd) confirmed the satisfactory agreement between the second-order regression model and the experimental data, affirming the optimization validity of the electrocoagulation process. In binary systems, copper presence hindered cadmium removal, reducing efficiency from 63.63% to 50.91%. Conversely, the inhibitory effect on copper removal was comparatively lower due to copper's stronger selectivity towards Al(OH)3.

Physical disability makes it hard for a person to take a walk, run, watch closely, and do other usual life tasks. Similarly, being mischievous is something that is expected to be part of a child’s nature. Fun encourages all children to have an opportunity to be united with others of the same age. The analysis of various types and elements of physical disabilities in children including the rationale of play therapy, enables to identify the significance of the program to their development. Play therapy is highlighted among other strategies to be used in enhancing inclusivity while gaining the interest of a child, thus increasing the overall result and experience of a child-oriented program. This research will focus on evaluating the use of play therapy to create better ergonomics and an atmosphere that is friendly to children with physical disabilities, particularly through the use of architectural design strategies. The study will be conducted by interviewing professionals in play therapy and reviewing and analysis of the literature to see what the building design features include. A case study on the precedent buildings shows the different types of rooms and design strategies for play therapy in them through factors like layout, wayfinding, ventilation, lighting, and outdoor and indoor play areas. Thus, the research results in the core design parameters to be considered while designing the center that will be used in the provision of the play therapy program for children with physical disabilities.

Steganography is essential in modern cryptography and communications, enhancing the security and confidentiality of sensitive data exchanges. It has become an interesting tool because not only have security requirements for secret messages become stronger, but video has also become more popular. This paper introduces an advanced method combining sequence-to-sequence transformer models for speech recognition, RC4 encryption, and the Least Significant Bit (LSB) technique for data embedding in videos. The approach securely embeds audio messages within video streams, ensuring that even if detected, the data remains inaccessible without the decryption key. Our methodology includes converting audio to text, encrypting it, and embedding the encrypted data into video files, with a subsequent recovery process that preserves the original audio's emotional and tonal qualities. Evaluations using the UCF101 dataset confirm the method's effectiveness in maintaining video quality, with minimal visual distortion, and robust data security. This research provides a secure framework for covert communication, with potential applications in areas requiring high-level data privacy.

The exploitation of locally available and abundant natural resources such as silica sand and its use as a supplementary cementitious material in the production of grout used in semi-flexible pavement (SFP) surfaces is of paramount importance in reducing transportation costs and emissions, contributing to more sustainable development practices, and reducing the overall environmental impact of cement plants. SFP or injected pavement, is a porous asphalt structure with 25–35% voids, filled with cementitious grout. SFP is distinguished by its robustness, resistance to deformation, and exceptional longevity, enabling it to endure substantial traffic loads and extreme weather conditions, hence offering a strong and dependable road surface that is comparatively simpler to maintain than other road construction types. This study focuses on developing a novel sustainable cementitious grout for SFP by partially substituting traditional cement with quartz silica sand powder (QSP) in different proportions (10%, 20%, and 30%). The grout mixtures were evaluated for flow and mechanical properties. Also, SFP samples were made by adding a 5% SBS modifier to a hot mix porous asphalt (HMPA) and then filling the holes with a predesigned cement-based grout then these samples were assessed for Marshall stability and moisture damage resistance tests. The results demonstrated that replacing cement with more than 10% of QSP reduces compressive strength and stability. This is due to the reduction in workability caused by water absorption in the grout mixture. This, in turn, increases the water-to-cement ratio to achieve the required fluidity, as well as increasing the porosity and decreasing the volume of hydration products. Therefore, this study suggests that 10% of QSP is the optimum replacement ratio as it achieves the required fluidity and increases the compressive strength, stability, and tensile strength ratio by 20.7%, 13.4%, and 12.0% respectively at 28 days of curing compared to the reference grout mixture. This mixture is considered suitable as it combines the properties of durability and environmental objectives by reducing the grinding energy and its use in severe conditions.

Organizational Factors Influencing Foreign African Court Interpreting in South Africa
Authors: Usadolo Sam Erevbenagie
Published: January 2025

Employee performance is influenced by organizational factors that require careful management by the human resource divisions of organizations. The involvement of human resources divisions is essential for managing court interpreters who require specific skills, such as understanding court hierarchies, proceedings, and discourse, remaining neutral concerning their language choices, and coping with hearing about sometimes horrific events without succumbing to secondary trauma. The organizational factors in the South African courtrooms were examined by interviewing foreign African court interpreters, magistrates, prosecutors, and attorneys. Observations of courtroom proceedings complement data collected through interview methods. The data analyzed show that the majority of foreign African court interpreters have employment on a casual rather than permanent basis, and organizational issues such as standardized employment procedures, in-service training, monitoring, induction, and orientation, amongst other factors, still require significant improvement to ensure quality foreign African court interpreting in South African courtrooms. The research contributes to the literature on human resources management of court interpreting. The implications of the findings and the limitations of the study are discussed.

Temporally dissociable neural representations of pitch height and chroma
Authors: Chang Andrew , Poeppel David , Teng Xiangbin
Published: January 2025

The extraction and analysis of pitch underpin speech and music recognition, sound segregation, and other auditory tasks. Perceptually, pitch can be represented as a helix composed of two factors: height monotonically aligns with frequency, while chroma cyclically repeats at doubled frequencies. Although the early perceptual and neurophysiological mechanisms for extracting pitch from acoustic signals have been extensively investigated, the equally essential subsequent stages that bridge to high-level auditory cognition remain less well understood. How does the brain represent perceptual attributes of pitch at higher-order processing stages and how are the neural representations formed over time? We used a machine learning approach to decode time-resolved neural responses of human listeners (10 females and 7 males) measured by magnetoencephalography across different pitches, hypothesizing that different pitches sharing similar neural representations would result in reduced decoding performance. We show that pitch can be decoded from lower-frequency neural responses within auditory-frontal cortical regions. Specifically, linear mixed-effect modeling reveals that height and chroma explain decoding performance of delta band (0.5-4 Hz) neural activity at distinct latencies: a long-lasting height effect precedes a transient chroma effect, followed by a recurrence of height after chroma, indicating sequential processing stages associated with unique perceptual and neural characteristics. Furthermore, the localization analyses of the decoder demonstrate that height and chroma are associated with overlapping cortical regions, with differences observed in the right orbital and polar frontal cortex. The data provide a perspective motivating new hypotheses on the mechanisms of pitch representation.
Beyond language impairments in post-stroke aphasia: A critical review
Authors: Mancini Simona , Arellano Karen
Published: January 2025

Although poststroke aphasia has traditionally been defined as a language disorder, some studies have suggested that other cognitive abilities might also be affected. The purpose of this review was to examine the extent to which impairments in domain-general abilities such as memory, attention, executive functions, and reasoning co-occur in people with aphasia (PWA) due to stroke. A search was conducted for studies that assessed both language and domain-general abilities behaviorally in people with aphasia and were published between the year range 2000-2023 in multiple databases. Synthesis of the results was organized according to the interactions between domain-general and linguistic abilities investigated by each study. We reviewed 23 studies in total. Overall, the articles included showed evidence for a significant prevalence of other cognitive deficits in post-stroke aphasia that interact with the severity of linguistic impairment, functional communication, and recovery outcomes. We highlight some methodological factors that should be considered when studying the relationship between language and domain-general impairments in the recovery of post-stroke aphasia, as well as the still unanswered questions about such interaction and the clinical implications of acknowledging that aphasia is not only a spectrum of profiles with diverse language impairments but also altered cognitive abilities.
The Relationship between Attitudes Toward Remote Learning and Work and Attitudes Toward Learning and Work in the Classroom and Office
Authors: Perlman Amotz
Published: January 2025

The development of computers and the Internet has transformed our lives beyond recognition. Learning, working, shopping, and navigating while driving have all evolved significantly compared to just a few years ago.This study explored the relationship between attitudes toward physical activity in the real world and attitudes toward activity in the digital environment. We examined the relationship between attitudes toward learning, working, navigating, and receiving services in online (digital) environments and those in physical environments. The study utilized self-report questionnaires to assess the attitudes of participants. A negative relationship was identified between attitudes toward traditional classroom learning and attitudes toward learning in a digital environment. This finding indicates that the two types of classrooms are perceived as distinct environments rather than as a single unified space.A negative relationship was identified between attitudes toward office work and those toward remote work. This finding indicates that the two work environments are perceived as distinct rather than as a single environment.A negative relationship was also identified between attitudes toward navigation without computers and attitudes toward navigation using computers. This finding indicates that the two navigation environments are perceived as distinct rather than a single environment.In contrast, a positive relationship was identified between attitudes toward services provided through digital means and those provided by human agents. This finding suggests that the service experience delivered through digital channels is similar to that provided by human agents.
Understanding factors that impact vehicle travel times on urban road networks using machine learning approaches

While travelers may have the same origin and destination for their trips, these trips may be associated with different travel times. Understanding what factors contribute to different travel times contributes to better transportation planning and driver experience improvement. Big mobile device data offers new opportunities to understand travelers’ driving behaviors by providing high-resolution trip trajectory data. In this study we analyzed factors including driver behaviors, built environment and road characteristics, and external factors (e.g., traffic incidents and weather), for their contributions to travel times for two different travel contexts, commuting in an urban environment and rural trips involving a vacation destination, using machine learning approaches including time-series clustering and Random Forest regression models. We found that specific driver route choices (i.e., the different routes that drivers followed including the use of highways or local roads), and individualized travel speed behaviors including speeding contributed to variations in travel times. Vehicle profiles (i.e., types of vehicle drivers used) and road incidents had different impacts for different trip contexts. These results are useful for urban and transportation planners seeking mitigations that reduce travel time along heavily traveled driving routes and contribute to determining more accurate travel time predictions.
Alternative pathways to Social Work licensure: A critical review and social equity policy analysis

Published: January 2025

PurposeIn August 2022, the Association of Social Work Boards released a long called for pass rate analysis that revealed significant disparities. While many states look to cease the requirement of the Bachelors, Masters, and Advanced Generalist exams in their licensure process, status quo bias leads to hesitancy to remove the requirement of the Clinical exam.MethodA critical review was undertaken to identify possible alternatives to the current multiple-choice competency-based exam which yielded three assessment formats (oral exams, portfolios, and performance assessment/simulations) and two alternatives (jurisprudence exams and provisional licensure). Informed by an Afrocentric lens, we undertook a social and racial policy analysis to examine alternative pathways for licensure from the perspective of a social work board member. We centered our analysis on the impacts on (1) Black social workers, who currently have the highest pass-rate disparities; (2) social workers whose primary language is not English, and (3) social workers with disabilities who have anecdotally reported difficulty with getting testing accommodations. We rated each alternative on four social equity analysis criteria of procedural fairness, access, quality, and outcomes. These ratings were computed into an overall rating for each alternative from equitable to inequitable.ResultsWe found jurisprudence exams and provisional licensure have the best possibility of being equitable pathways to licensure, with potential impacts on the regulation of supervision and continuing education. ConclusionAnti-racism and social justice as praxis require social work as a profession to divest from competency-based testing to eliminate racism in our own professional policies.
Bridging Impact and Governance: Exploring the Nexus of Social Entrepreneurship and Politics for Global Challenges
Authors: Aryal Diwakar
Published: January 2025

Social entrepreneurship and politics have traditionally operated in separate domains, yet their convergence offers unparalleled potential for addressing global challenges. This study explores the integration of social entrepreneurial strategies with political governance to combat pressing issues such as climate change, digital inclusion, global health crises, and social empowerment. The objective of the research is to analyze opportunities and challenges within this intersection and propose actionable frameworks for leveraging the strengths of both spheres. Employing a qualitative methodology, this study synthesizes secondary data, including policy reports, case studies, and academic literature, to evaluate the effectiveness of collaborative strategies. Findings reveal that social entrepreneurs can significantly influence policy and implementation by innovating sustainable solutions while policymakers amplify these impacts through scaling and systemic integration. The study concludes that fostering collaboration between social entrepreneurship and politics can yield transformative outcomes, creating a model of governance that is ethical, inclusive, and results-oriented.
