Navigating the Waves: The Global Pandemic's Impact on Container Shipping and Freight Rates Across Different Policy Scenarios

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT The COVID‐19 pandemic has reverberated across global industries, including the international container shipping industry, where freight rates have become highly volatile. However, shipping lines appeared to thrive, particularly during the pandemic's initial 2 years.

Fast Shapley Value Approximation Through Machine Learning With Application in Routing Problems

open access: yesNetworks, EarlyView.
ABSTRACT For many routing applications, it is not only necessary to minimize total costs but also to allocate them to individual customers. In this context, the allocation according to the Shapley value is a well‐known method highly regarded for its fulfillment of major fairness criteria.

Probing Enzymatic Acetylation Events in Real Time With NMR Spectroscopy: Insights Into Acyl‐Cofactor Dependent p300 Modification of Histone H4

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Lysine acylation is a rapidly expanding class of post‐translational modifications with largely unexplored functional roles; the study of acylations beyond acetylation is especially impeded by limited methods for their preparation, detection, and characterization in vitro. We previously reported a nuclear magnetic resonance (NMR)‐based approach

Enhancing Circular Economic Activities of e‐Waste Pickers in South Africa: Using Korten's Four Generations Strategies as Framework

open access: yesSustainable Development, EarlyView.
ABSTRACT E‐waste pickers play a valuable role in the circular economy and divert waste from landfills. Despite their contributions to the economy, informal e‐waste pickers work in very adverse conditions. With a view to improving their livelihoods and working conditions and possibly increasing their integration, Korten's four generations framework is ...

A combined concrete cone breakout—pull‐out model for cast‐in‐place fasteners

open access: yesStructural Concrete, EarlyView.
Abstract Cast‐in‐place fasteners are widely used in civil engineering to connect steel or other elements to reinforced concrete. Despite the inherent importance of such components in structural design, the introduction of dedicated mechanical models for their verifications is quite recent.

Categorizational Asymmetries in Context: Producing and Resisting Policeable Scenes

open access: yesSymbolic Interaction, EarlyView.
This article examines categorizational asymmetries observable in the attempted production and negotiation of a “policeable” scene. The case described in the article—an encounter between a police officer and a black male student treated as “out of place”—demonstrates how members accomplish, negotiate, and resist categorial “statuses” and associated ...

Inference for double Pareto lognormal queues with applications [PDF]

open access: yes, 2008
In this article we describe a method for carrying out Bayesian inference for the double Pareto lognormal (dPlN) distribution which has recently been proposed as a model for heavy-tailed phenomena. We apply our approach to inference for the dPlN/M/1 and
