Reflections on Comparative Teaching in Public Administration

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT This article integrates our scholarly experience of teaching comparative public administration. In doing so, we offer a unique perspective as the co‐authors carry several diverse attributes, among them their countries of origin, current country in which they are teaching, and their academic experience.

Technopolitical Energy Governance as Administrative Closure: Digitalisation and the Depoliticisation of Energy Politics in Iran and Saudi Arabia

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT Digitalisation is widely framed as a route to more efficient and participatory public administration. In authoritarian settings, however, digital governance often works less as administrative improvement than as a technopolitical instrument for managing dissent and insulating policy from contestation.

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

open access: yesPolymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Leucaena Oil Functionalized With Osmium Tetroxide as a Precursor for Polyol‐Based Polyurethane

open access: yesJournal of Polymer Science, EarlyView.
Leucaena leucocephala seed oil is converted into a hydroxyl‐functional biopolyol through OsO4‐mediated dihydroxylation. The resulting biopolyol shows a hydroxyl number of 160–175 mg KOH g−1 and is successfully used to produce flexible, open‐cell polyurethane foams, highlighting a renewable route for converting underutilized biomass into value‐added ...

Correcting Left‐Truncation Bias in Weibull Reliability Analysis: Synthetic Data Validation for Electrical Utility Assets

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT Incomplete historical records in utility asset datasets frequently introduce left‐truncation bias, leading to distorted reliability estimates and suboptimal asset management decisions. This study presents a systematic framework for validating left‐truncation correction in Weibull reliability analysis using synthetic data representative of ...
