Unveiling The Diversity Within Salvia Caespitosa Sensu Lato (Lamiaceae): Three New “Hidden” Endemic Species From Türkiye​, Ferhat Celep, Musa Doğan, Gali̇p Akaydin, Ahmet Kahraman, Ersi̇n Karabacak, Ömer Çeçen, Meti̇n Armağan, Chun-Lei Xiang, Bryan T. Drew Jul 2026

Unveiling The Diversity Within Salvia Caespitosa Sensu Lato (Lamiaceae): Three New “Hidden” Endemic Species From Türkiye​, Ferhat Celep, Musa Doğan, Gali̇p Akaydin, Ahmet Kahraman, Ersi̇n Karabacak, Ömer Çeçen, Meti̇n Armağan, Chun-Lei Xiang, Bryan T. Drew

Turkish Journal of Botany

Documenting species, particularly those that are threatened or endangered, is fundamental to biodiversity conservation. However, many taxa remain scientifically unrecognized, being either undiscovered or unpublished. While some plants can be easily recognized as new species, other identifications are obscured by morphological, taxonomic, and nomenclatural complexity. Detecting cryptic or “hidden” species is therefore essential to understanding biodiversity and plant evolution. Our revisionary studies on Salvia demonstrate that the morphologically complex Salvia caespitosa is not a single species but instead comprises at least four distinct species, three with narrow distributions. This conclusion is supported by integrative evidence from extensive field studies, herbarium …

Evolutionary Neural Architecture Search: A Survey, Ferda Nur Özçeli̇k, Mehmet Önder Efe Jul 2026

Evolutionary Neural Architecture Search: A Survey, Ferda Nur Özçeli̇k, Mehmet Önder Efe

Turkish Journal of Electrical Engineering and Computer Sciences

Deep Neural Networks (DNNs) have achieved remarkable success across diverse machine learning applications, yet designing effective architectures remains a laborious, expert-driven process. Neural Architecture Search (NAS) was introduced to automate this process, with Evolutionary NAS (ENAS) emerging as one of the most effective and widely adopted NAS paradigms. This survey provides a comprehensive and systematic review of 164 ENAS studies published between 2020 and 2024, categorized according to the specific evolutionary algorithm employed as the search strategy. Unlike prior surveys—which either treat evolutionary methods at a high level or focus on general NAS pipelines—this study is, to the best of …


State Engagement In Trump Accounts: A Policy-Design And Implementation Framework, Center For Social Development, Washington University In St. Louis, Pennsylvania Treasury Department Jul 2026

State Engagement In Trump Accounts: A Policy-Design And Implementation Framework, Center For Social Development, Washington University In St. Louis, Pennsylvania Treasury Department

Center for Social Development Research

Trump Accounts are IRAs for American children, with a $1,000 federal seed contribution available for those born from 2025 through 2028. Under the current design, families must take two separate steps to request an account. Children whose families do not complete both steps will receive neither the account nor the federal deposit. They also will be excluded from employer matches, philanthropic contributions, and other general contributions to Trump Accounts. The current opt-in design will leave behind the children who need the program most. States are well positioned to address this gap. This Policy Brief proposes a framework for state engagement …


Enhancing Resonance Wave–Matter Interaction In Finite-Size Dielectric Metasurfaces, Varsha Vijay Kumar, Elena Semouchkina Jul 2026

Enhancing Resonance Wave–Matter Interaction In Finite-Size Dielectric Metasurfaces, Varsha Vijay Kumar, Elena Semouchkina

Michigan Tech Publications

We investigate the dramatic effects produced by the presence of physical boundaries of finite-size metasurfaces (MSs), composed of identical cylindrical dielectric resonators without broken symmetry, on the complexity of their responses, observed at normal plane wave incidence, when constituent particles can support only dipolar Mie resonances. We demonstrate the possibility to excite extra high-quality resonance modes in these finite structures, which are quite distinct from the modes in infinite structures. We explore the formation of different types of high-quality modes in MS fragments of different configurations and sizes, which makes it possible to provide guidance for configuring their optimal designs. …


Integrative Data Inform The Taxonomy Of Salix: A Case Study Of S. Purpurea L. Subsp. Leucodermis Yalt. (Salicaceae) From Türkiye, Peli̇n Acar, Yasi̇n Kaya, Dudu Özlem Mavi̇ İdman, Irina V. Belyaeva Jul 2026

Integrative Data Inform The Taxonomy Of Salix: A Case Study Of S. Purpurea L. Subsp. Leucodermis Yalt. (Salicaceae) From Türkiye, Peli̇n Acar, Yasi̇n Kaya, Dudu Özlem Mavi̇ İdman, Irina V. Belyaeva

Turkish Journal of Botany

The study of endemic species provides valuable perspectives on evolutionary history and future targets for their conservation. Salix purpurea L. subsp. leucodermis Yalt., which is endemic to Sandras Mountain in Türkiye, was analysed using morphological, anatomical, and genomic methods. This study presents the first draft short-read sequence of S. purpurea subsp. leucodermis, providing preliminary genomic evidence of differentiation from related taxa. This study also revealed a specific combination of anatomical features (prominent calcium oxalate crystals and amphistomatous leaves) and morphological characteristics (striated wood, glabrous buds, absence of stipules) that differentiate the taxon in question from the closely related species S. …

A Revenue-Driven Approach For Enhanced Task Utilization In Vehicular Cloud Computing, Ashish Singh Saluja, Satyabrata Das, Sanjib Kumar Nayak, Sohan Kumar Pande

Turkish Journal of Electrical Engineering and Computer Sciences

Vehicular networks support intelligent transportation through vehicle-to-roadside Units (V2R) and vehicle-to-vehicle (V2V) communication but face challenges from dynamic topologies, limited RSU coverage, and bandwidth scarcity, which impact service delivery and revenue. RDA-ITU addresses these challenges by integrating V2R and V2V paradigms to maximize RSU revenue, enhance service availability, and improve system efficiency. It dynamically allocates services based on real-time network conditions and vehicle mobility, leveraging V2V relays to optimize both RSU-direct and cooperative communication. Through extensive simulations, RDA-ITU significantly outperforms four baselines: RBSM, VVMM-U, VVMM-LW, and VVMM-MA. It achieves 81.1% higher total revenue, 154.8% more completed requests, and 103.6% higher …


Class-Aligned Frequency Augmentation Using Variational Mode Decomposition Forfew-Shot Image Classification, Leila Boussaad Jul 2026

Class-Aligned Frequency Augmentation Using Variational Mode Decomposition Forfew-Shot Image Classification, Leila Boussaad

Turkish Journal of Electrical Engineering and Computer Sciences

Few-shot image classification benefits from data augmentation, yet most existing methods operate in pixel space with limited control over spectral semantics. We introduce a lightweight, frequency-guided augmentation strategy based on Variational Mode Decomposition (VMD). Our method constructs an offline, per-class ModeBank by decomposing downsampled luminance patches and retaining midband modes that encode class-specific texture patterns. During episodic training, VMD is never executed online: instead, for each support image, a same-class midband mode is selected and blended using PSNR-targeted scaling with a luminance energy cap, ensuring perceptual consistency. The augmentation is fast, reproducible, class-consistent, and integrates seamlessly into standard metric-based pipelines …


Beyond Sticky Floors: Executive Gender Diversity And Firm-Level Gender Pay Inequality In Uk Firms, Yasser Eliwa, Sally Ahmed, Ahmed Saleh Jul 2026

Beyond Sticky Floors: Executive Gender Diversity And Firm-Level Gender Pay Inequality In Uk Firms, Yasser Eliwa, Sally Ahmed, Ahmed Saleh

All Works

This study examines whether executive gender diversity is associated with gender pay inequality in UK firms. Although prior research has extensively examined board diversity, less is known about whether gender diversity within executive leadership teams is linked to differences in pay inequality across firms. Using a panel of FTSE 350 non-financial firms from 2017 to 2023 and mandatory UK gender pay gap disclosures, we estimate regression models to examine the relationship between the proportion of female executives and the gender pay gap. The findings show that greater executive gender diversity is significantly associated with lower gender pay inequality. In contrast, …

577 Vanderbilt Llc V. Hassell

All Decisions

Landlord commenced a nonpayment proceeding demanding the legal regulated rent. In 2018, landlord's predecessor-in-interest settled a prior nonpayment proceeding by two-attorney stipulation, granting tenant a preferential rent of $1,750 set to expire August 14, 2024. After HSTPA's enactment on June 14, 2019, RSL §26-511(c)(14) and RSC §2521.2(d) were amended to require that any tenant paying a preferential rent as of HSTPA's effective date be charged no more than that preferential rent for the lifetime of the tenancy. Tenant moved for summary judgment. The court granted the motion, holding that the 2018 stipulation's expiration date became unenforceable after HSTPA, that applying …

Human Experts' Assessment, Marcello Di Pumpo, Leonardo Villani, Maria Rosaria Gualano, Danilo Buonsenso, Francesca Raffaelli, Daniele Donà, Patrizia Laurenti, Vittorio Maio, Stefania Boccia, Walter Ricciardi Jul 2026

Llm-As-A-Judge For Infection Prevention And Control And Antimicrobial Resistance Impact: Comparing Three Main Llms Vs. Human Experts' Assessment, Marcello Di Pumpo, Leonardo Villani, Maria Rosaria Gualano, Danilo Buonsenso, Francesca Raffaelli, Daniele Donà, Patrizia Laurenti, Vittorio Maio, Stefania Boccia, Walter Ricciardi

College of Population Health Faculty Papers

BACKGROUND: Large language models (LLMs) are increasingly used to generate health information, yet their reliability as evaluators remains unclear. This study investigated the feasibility of an LLM-as-a-judge methodology in the context of infection prevention and antimicrobial resistance (AMR), comparing automated ratings with human expert benchmarks.

METHODS: We performed a secondary analysis of an expert-annotated dataset of health messages. Three leading LLMs (ChatGPT, Claude, Gemini) independently evaluated the same messages using an adapted DISCERN tool across five domains: information reliability, quality, AMR impact, persuasiveness, and overall score. We utilized descriptive statistics, intra-rater reliability tests, and mixed-effects ordinal regression to analyze divergence …


Our Children Are Sacred: Faith, Disability Justice, And Educational Hope, Charles E. Becknell Jr., Pricella Morris, Monique Matute-Chavarria, Deirdre A. Williams Jul 2026

Our Children Are Sacred: Faith, Disability Justice, And Educational Hope, Charles E. Becknell Jr., Pricella Morris, Monique Matute-Chavarria, Deirdre A. Williams

The Journal of Faith, Education, and Community

This manuscript examines how Black families interpret dis/ability through faith, caregiving, and communal life using Sacred Narrative Inquiry (SNI), a collaborative approach that treats family stories as sources of sacred and cultural knowledge. Grounded in disability theology and informed by Black liberation theology and Womanist epistemology, the study explores how families understand dis/ability as sacred and embodied, shaped by struggle, endurance, and hope. Through shared storytelling and collective interpretation, the analysis identifies recurring patterns of early moral formation, embodied knowledge that precedes institutional recognition, faith as a sustaining practice under constraint, and moments of recognition that affirm dignity and interrupt …


God > Grit: A Phenomenological Analysis Of Intrinsic And Extrinsic Motivating Factors For Black Male Students Previously Labeled “At-Risk”, Marcia J. Watson-Vandiver Jul 2026

God > Grit: A Phenomenological Analysis Of Intrinsic And Extrinsic Motivating Factors For Black Male Students Previously Labeled “At-Risk”, Marcia J. Watson-Vandiver

The Journal of Faith, Education, and Community

This phenomenological study examines the intersections of faith, learning, and racialized experiences in K-12 schooling. In doing so, this research explores the experiences of Black[1] males in U.S. public schools who were once labeled academically or behaviorally “at risk.” Here, at-risk is a term that typically applies to students “in jeopardy of progressing academically due to circumstances that may impact educational performance” (MSDE, 2018). While the purview of academic, school discipline, and behavior discourse are saturated with conversations on racial disparities, the exigent problem still remains. As such, this research provides a nuanced probe into intrinsic and extrinsic motivating …


Perceptions Of The Divine In Secular Spaces: A Study Of U.S. Public-School Teachers, Dennis Eastman, Nicholas Block Jul 2026

Perceptions Of The Divine In Secular Spaces: A Study Of U.S. Public-School Teachers, Dennis Eastman, Nicholas Block

The Journal of Faith, Education, and Community

Teaching is often understood by Christian educators as a vocation shaped by divine purpose, yet little empirical research has examined how teachers perceive God’s active involvement in their daily professional practice. This qualitative study investigates how Christian teachers interpret perceived divine activity in their work, focusing on specific experiences of guidance, influence, and sustenance rather than general religious identity. Thematic analysis of open-ended survey responses from practicing teachers (N = 267) identified seven themes, including perceived impact on students’ lives, divine guidance in instructional and relational decisions, and endurance amid professional strain. Participants commonly described God’s activity as …


Teaching As Testimony: Examining The Relationship Between High School Teachers’ Faith Identity And Pedagogy, Candace M. Kyles Jul 2026

Teaching As Testimony: Examining The Relationship Between High School Teachers’ Faith Identity And Pedagogy, Candace M. Kyles

The Journal of Faith, Education, and Community

Teaching has long been understood within Christian theology as a vocational practice shaped by faith, moral formation, and lived discipleship. Yet within U.S. public schooling, the Separation of Church and State restricts explicit engagement with religion, often rendering educators’ faith identities invisible within school buildings and classrooms. This covertness does not eliminate the formative influence of faith; rather, it obscures how teachers’ faith identities inform their ethical reasoning, teaching practices, and pedagogical choices. When faith remains unexamined, it may operate implicitly, shaping classroom interactions without the benefit of critical reflection or institutional support.

Despite the prominence of culturally responsive pedagogy …


Reintegrating Wisdom: A Cultural-Sciences Framework For Linking Music, Faith, And Stem Education, Yoonil Auh, Minjeong Cho, Sang-Eun Hwang Jul 2026

Reintegrating Wisdom: A Cultural-Sciences Framework For Linking Music, Faith, And Stem Education, Yoonil Auh, Minjeong Cho, Sang-Eun Hwang

The Journal of Faith, Education, and Community

This article proposes a theoretical model for integrating music and religious education into STEM by reframing them as cultural sciences, disciplines that generate symbolic, ethical, relational, and meaning-making forms of knowledge essential for 21st-century learning. While technocratic models of STEM emphasize quantification, efficiency, and innovation, they often marginalize the humanistic and spiritual dimensions of education that support ethical discernment, cultural literacy, and communal responsibility. Drawing on epistemic pluralism, transdisciplinary studies, educational philosophy, theology, and music pedagogy, this study outlines a four-dimensional framework, epistemic integration, transdisciplinary learning, ethical praxis, and spiritual-communal ways of knowing, that positions music and religious education not …

Application Of Assistive Technologies And Rendering Assistive Services To Students With Special Needs By Federal University Libraries: A Survey, Emmanuel Chidiadi Onwubiko

Library Philosophy and Practice (e-journal)

The world as of today, is being said to be witnessing what one may tagged a technological revolution as never before and is transforming for the better, the future of global education in which case, every learner is considered. These newly created technological tools and plans did place librarians as information managers and digital literacy drivers in better position to come up with environments that are inclusive for all learners to achieve their desired goals. The study therefore is a survey on the application of assistive technologies and rendering assistive services to students with special needs by federal universities libraries …


Hold-Then-Release Safety-Gated Streaming With Dual-Lane Classification And Abuse-Sample Harvesting For Anonymous Public Llm Surfaces, Gustavo Matthew Assuncao Jul 2026

Hold-Then-Release Safety-Gated Streaming With Dual-Lane Classification And Abuse-Sample Harvesting For Anonymous Public Llm Surfaces, Gustavo Matthew Assuncao

Defensive Publications Series

This defensive publication discloses a runtime architecture for anonymous, unauthenticated public large-language-model (LLM) surfaces — the "ask a question" box on a marketing website, a public demo endpoint, an embedded help widget — that simultaneously preserves token-by-token streaming user experience and enforces an absolute zero-leak output-safety guarantee. The core mechanism is hold-then-release: the final model answer is streamed from the inference backend into an in-process delta buffer and is never forwarded to the client during generation; output safety executes against the fully assembled answer text; only a clean (or explicitly flagged-but-tolerated) verdict causes the buffered deltas to be replayed to …


Generalized Transaction-Local Provenance-Marker Single-Writer Column Enforcement With Co-Designed Forgery Scanner And Non-Vacuity Red-Team, Gustavo Matthew Assuncao Jul 2026

Generalized Transaction-Local Provenance-Marker Single-Writer Column Enforcement With Co-Designed Forgery Scanner And Non-Vacuity Red-Team, Gustavo Matthew Assuncao

Defensive Publications Series

This document discloses, enables, and dedicates to the public a generalized database-integrity primitive together with its co-designed hardening. The primitive makes a protected state column writable only by a transaction that has, within the same transaction, appended a matching row to an append-only decision log. The linkage is realized without any application-level privilege: an AFTER INSERT trigger on the log writes a transaction-local marker (PostgreSQL setconfig(..., TRUE)) encoding the exact subject tuple and outcome just logged, delimited by the ASCII Unit Separator (chr(31)); a BEFORE UPDATE guard on the protected column raises an exception unless a same-transaction marker exists whose …


Capability-Gate-First Cost-Optimal Llm Task Router With Monotone Hard-Capability Taint, Dif-Fairness-Governed Escalation, And Cheapest-Allowed Self-Clamp, Gustavo Matthew Assuncao Jul 2026

Capability-Gate-First Cost-Optimal Llm Task Router With Monotone Hard-Capability Taint, Dif-Fairness-Governed Escalation, And Cheapest-Allowed Self-Clamp, Gustavo Matthew Assuncao

Defensive Publications Series

This document discloses, in enabling detail, a method and system for selecting, on a per-turn basis, which large language model (LLM) answers a given request in a multi-model deployment. The distinguishing property is that capability feasibility is a hard gate evaluated strictly before any cost or difficulty optimization, and a budget is structurally unable to override a capability-forced selection. A four-stage task assessor emits a set of required capability primitives (tooluse, vision, longcontext) under a monotone taint invariant: each later stage may raise, but never lower, a hard requirement detected by an earlier stage, while websearch is deliberately kept soft …


Tails From The Isle Of Devils: Two New Records Of Non-Native Invasive Scorpions (Arachnida: Scorpiones) Successfully Intercepted In Bermuda, Including The First Record Of Caraboctonidae, Danniella Sherwood, Mark Outerbridge, Struan R. Smith, Jenny Gosling, Myles Darrell Jul 2026

Tails From The Isle Of Devils: Two New Records Of Non-Native Invasive Scorpions (Arachnida: Scorpiones) Successfully Intercepted In Bermuda, Including The First Record Of Caraboctonidae, Danniella Sherwood, Mark Outerbridge, Struan R. Smith, Jenny Gosling, Myles Darrell

Euscorpius

Hadruroides sp. (Scorpiones: Caraboctonidae) is newly recorded as a successfully intercepted non-native invasive species in Bermuda, based on examination of a desiccated and damaged immature female specimen. A second record of an intercepted Centruroides gracilis (Latreille, 1804) (Scorpiones: Buthidae) is reported based on examination of an adult male.


An Analysis Of The Law On The Prohibition Of Fraud In Goods, Samira Krourou Jul 2026

An Analysis Of The Law On The Prohibition Of Fraud In Goods, Samira Krourou

Revue Marocaine de Droit, d'Economie et de Gestion (Moroccan Journal of Law, Economics and Management)

One of the most important aspects of consumer protection is the fight against fraud in goods—a form of protection enshrined in the Abrahamic religions long before the enactment of positive laws or the emergence of consumer advocacy movements that spread from the United States to Europe and the rest of the world. While fraud in general is indicative of a malicious tendency to infringe upon rights, spread corruption, and undermine interests, fraud involving goods and food is an even more heinous and dangerous crime because it affects the health and lives of both humans and animals. Therefore, it was necessary …


Cybersecurity Governance Of Industrial Iot In Sub-Saharan Africa: Policy Gaps, Threat Landscape, And Lessons From Comparative African Contexts, Faztudo Languisse Eng. Jul 2026

Cybersecurity Governance Of Industrial Iot In Sub-Saharan Africa: Policy Gaps, Threat Landscape, And Lessons From Comparative African Contexts, Faztudo Languisse Eng.

Journal of Cybersecurity Education, Research and Practice

The rapid deployment of Industrial Internet of Things (IIoT) systems across Sub-Saharan Africa's extractive, energy, logistics, and agro-industrial sectors has introduced a cybersecurity challenge of growing urgency: industrial networks that were designed for operational efficiency are increasingly exposed to cyber threats for which neither the organizations nor the regulatory frameworks are adequately prepared. This article examines the cybersecurity governance of IIoT systems in a developing African economy, using Mozambique as a primary case study and drawing comparative lessons from South Africa, Rwanda, and Kenya. Through an integrative literature review and documentary analysis of national digital, cybersecurity, and industrial policies, the …

Ai Pedagogical Enactment Framework (Ai-Pef): A Framework For Shared Pedagogical Enactment Of Artificial Intelligence, Rashan E. Isaac

Departmental Papers (TE)

Artificital Intellegence (AI) has rapidly transformed teaching and learning for K-12 and higher education yet limitied guidence exits on how AI-grounded pedagogical enactments are devloped, observed, become sustainable, and extended over time. This paper introduces the AI Pedagogical Enactment Framework (AI-PEF) — a framework for shared pedagogical enacment of artificial intellengence. Shared pedagogical enactment is conceptualized as the process through which educators and eductional organizations developed a shared language, expectations, and practices for a given initative. AI-PEF is composed of six interconnected levers (Citation, Alignment, Application, Evaluation, Integration, and Extension), togeather providing a shared language for regnition and evalustion of …


Taxing Ai In The Wake Of The Emergence Of Agentic Ai, Reuven S. Avi-Yonah, Herbert Snitz Jul 2026

Taxing Ai In The Wake Of The Emergence Of Agentic Ai, Reuven S. Avi-Yonah, Herbert Snitz

Articles

This article addresses taxation measures to regulate AI agents (i.e., AI that is not fully under the control of humans, including both ANI and AGI). In each case, the focus is on what the agent’s capabilities would be, not on how it becomes capable of successfully performing its tasks (though the latter would likely be relevant to important philosophical questions, e.g., might robots achieve sentience or consciousness, and if so, would they have rights?). Regarding mirroring what we human beings can do, the hallmark of AGI is that it will not be task-specific (like ANI), but will possess broad capabilities, …


Comments Re: Regulation For Federal Financial Assistance, Fred D. Ledley, Edward Zhou, Brian C. Fox Jul 2026

Comments Re: Regulation For Federal Financial Assistance, Fred D. Ledley, Edward Zhou, Brian C. Fox

CISI Publication

This comment focuses on the proposed modifications to §200.205 “Federal Agency Merit Review of Proposals” and §200.340 “Termination and suspension” of Title 2 of the Code of Federal Regulations. We argue that the pre-issuance review, discretionary termination provisions, and other constraints of federal research support that would be established under this proposal create impediments to the scientifically-driven process of discovery and innovation that has long provided the foundation for advances in American prosperity, influence, health, and wellbeing. Our comments focus specifically on federal support for biomedical research by the National Institutes of Health (NIH) for the purpose of advancing healthcare …


Feasibility Of Using Untreated And Treated Rice Straw Fibers As A Modifier For Hot Mix Asphalt, Aditya Chowdhury Jul 2026

Feasibility Of Using Untreated And Treated Rice Straw Fibers As A Modifier For Hot Mix Asphalt, Aditya Chowdhury

Civil Engineering Theses

Flexible pavements are subject to progressive deterioration driven by repeated traffic loading, environmental exposure, and material degradation, which causes distress. This study presents an integrated research framework that combines laboratory performance evaluation of rice straw fiber (RSF)-modified hot mix asphalt with machine learning-based pavement distress prediction to advance sustainable pavements. Three plant-produced HMA mixtures were modified with untreated and alkali-treated RSF at dosage levels of 0.2%, 0.4%, and 0.6% by total mixture weight. FTIR spectroscopic analysis confirmed that alkali treatment induced significant chemical modifications to the fiber surface, increasing hydroxyl group availability and enhancing fiber–binder adhesion. Alkali-treated RSF consistently outperformed …


Incorporating Increased Road User Costs Into Pavement Management Modeling: A Case Study Of Two-Lane Rural Highways, Khaled A. Abaza, Mohamed S. Yamany Jul 2026

Incorporating Increased Road User Costs Into Pavement Management Modeling: A Case Study Of Two-Lane Rural Highways, Khaled A. Abaza, Mohamed S. Yamany

Faculty Publications

The impact of increased road user costs on optimal pavement rehabilitation plans has been investigated using a simplified pavement management model. The increased road user costs include elevated vehicle operating costs (VOCs) due to work-zone lane closures and traveling on severely deteriorated pavements. A model is proposed for estimating the VOC for work-zone lane closures on two-lane rural highways, considering both stopping and idling costs. Another model for approximating the increased VOC associated with driving on poor/bad pavements is suggested as a function of the relevant VOC rate and a proportionality factor. Sample results are presented for a two-lane rural …
