Which Decolonization? Theorizing Decolonization beyond Decoloniality and its Critics

Development and Change, EarlyView.
ABSTRACT The debate on decolonial thought has reached an unhelpful stalemate. A core problem in assessing decolonial thought is that the term ‘decolonization’ has been stretched so widely that it now allows for many competing uses. For some critics of decolonial thought such as Nigerian philosopher Olúfẹ́mi Táíwò, this overuse points to conceptual ...

An investigation of sleeper voids using a flexible track model integrated with railway multi-body dynamics [PDF]

, 2009
This article describes a flexible track system model (FTSM) that represents the track structure for a typical ballasted track, taking into account the flexibility of the rails, the sleeper mass and the resilience of the pad/fastening elements, as well as

From products to smart solutions: A value‐creation approach

European Management Review, EarlyView.
Abstract Smart solutions comprise a synergy of products, services, software, connectivity, data, and intelligence. This study examines the evolution of a manufacturer into a smart solution provider, highlighting the role of value‐creation capabilities, activities, and practices. Through a longitudinal, in‐depth single‐case study of a leading technology

Qualitative Analysis of Sleeper Supporting Condition for Railway Ballasted Tracks Using Modal Test

Applied Sciences
During railway operations, changes in the support conditions of sleepers, owing to various internal and external factors, can damage rails and concrete sleepers and alter the structural characteristics of gravel-ballasted tracks. However, current methods

The downward legacy of a phytoplankton bloom in the oligotrophic North Pacific Subtropical Gyre

Limnology and Oceanography, Volume 71, Issue 10, October 2026.
Abstract Ocean particles are a heterogeneous collection, including living and dead cells, feces, mucus‐rich aggregates, and mineral shells and frustules. In the well‐lit upper ocean, phototrophic processes fuel production of particulate matter; however, only a relatively small percentage (< 10% per day) of this material (mostly detrital) escapes the ...

Application of Polyurethane Polymer and Assistant Rails to Settling the Abnormal Vehicle-Track Dynamic Effects in Transition Zone between Ballastless and Ballasted Track

Shock and Vibration, 2015
This paper describes tests on a transition section between ballasted and ballastless tracks in the Liupanshui-Zhanyi railway in China. The originally unsettled transition zone is exposed to sudden car shaking and a series of track transition problems ...

Nonlinear dynamic responses of ballasted railway tracks using concrete sleepers incorporated with reinforced fibres and pre-treated crumb rubber

Nonlinear Engineering, 2023
Damages on railway sleepers due to heavy impact loads induced by the movement of trains can be reduced by improving their impact resistance. Fibre-reinforced/pre-treated crumb rubber concrete sleepers (RCSs) have the potential to display significant ...

Community Awareness and Evidence of Dugong (Dugong dugon) Presence in Anjouan, Comoros

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The dugong (Dugong dugon), listed as Vulnerable globally, is poorly documented in the Western Indian Ocean, including the Comoros. We combined Local Ecological Knowledge (LEK) and Passive Acoustic Monitoring (PAM) to assess occurrence and reported encounters around the island of Anjouan.
