Integrating Pavement Friction and Macrotexture into a Speed-Dependent Pavement Safety Metric for Safety Performance Modeling

open access: yesLubricants
The paper proposes a pavement safety index, the estimated available friction at the expected travel speed, FRS(v), to model the composed effect of low-slip speed friction and macrotexture on roadway crashes.

Climate Change Risks and Customer Concentration: Evidence From US‐Listed Firms

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT While prior studies have investigated climate risks in supply chains, customer ESG pressures, and shared climate exposure, this paper is, to the best of our knowledge, the first to provide direct empirical evidence on the relationship between climate change risks and firms' customer concentration.

Infrastructure associations of crash frequency and types in Sweden’s national road network with temporal instability during COVID-19

open access: yesEuropean Transport Studies
Despite advancements in road infrastructure and ongoing efforts to improve traffic safety, how infrastructure features relate to crash frequency and crash types, and how these associations vary across regions and over time, remains insufficiently ...

Green Is the New Gold: Redefining Opulent Lifestyle Through Organic Food Purchases

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Prior studies based on the Theory of Planned Behavior mostly examined the effects of health and environmental concerns on organic food consumption; however, few addressed the paradoxical relationships in the context of opulent or symbolic decorum.

Digital Transformation and Informal Innovation in Africa: Reframing STI Policy for Inclusive Circular Economy Transitions

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Amid increasing environmental and economic pressures, Africa's transition to a circular economy (CE) presents a vital pathway to inclusive, low‐carbon development. Yet, how digital transformation, informal innovation, and science, technology, and innovation (STI) policy readiness shape CE outcomes remains underexplored.

Covalent Attachment of a Platinum(II) Complex inside DNA Duplexes

open access: yesChemistryEurope, EarlyView.
Oxidative addition is used for the site‐specific incorporation of an organometallic PtII complex as an artificial nucleobase into a DNA duplex. The platination stabilizes the duplex and confers it with phosphorescence. An organometallic phosphorescent PtII complex is introduced into DNA duplexes via oxidative addition to a tailor‐made artificial ...

Bayesian clustering of multivariate extremes

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract The asymptotic dependence structure between multivariate extreme values is fully characterized by their projections on the unit simplex. Under mild conditions, the only constraint on the resulting distributions is that their marginal means must be equal, which results in a nonparametric model that can be difficult to use in applications ...

Predicting Number of Vehicles Involved in Rural Crashes Using Learning Vector Quantization Algorithm

open access: yesAI
Roads represent very important infrastructure and play a significant role in economic, cultural, and social growth. Therefore, there is a critical need for many researchers to model crash injury severity in order to study how safe roads are.
