The Art of Reception: Field Visits as Microcosms for Development Interventions of Non‐Governmental Organisations in Uganda

Journal of International Development, EarlyView.
ABSTRACT Field visits are common phenomena with non‐governmental organisations in Uganda. During these visits, Ugandan national staff guide visitors on series of meetings and interactions in the field. Following an actor‐oriented approach and drawing on ethnographic data on 14 field visits, this paper understands the field visit as a microcosm for the ...

Stair‐Climbing Wheelchairs for Enhanced Mobility: A Comprehensive Review of Fundamental Mechanisms, Design Concepts, and Performance Analysis

Journal of Field Robotics, EarlyView.
ABSTRACT People with physical disabilities face significant mobility challenges while climbing uneven surfaces and staircases. In these circumstances, traditional wheelchairs do not provide stable, safely controlled mobility, underscoring the importance of building superior stair‐climbing wheelchairs for both medical and infrastructure purposes.

Testing Times: A Structure/Agency Perspective on Becoming a Science Teacher in a Competitive, Exam‐Based Teacher Selection System

Science Education, EarlyView.
ABSTRACT While extensive research exists on science teacher shortages, less attention has been directed toward countries facing the opposite challenge: an oversupply of science teachers. This study examines the experiences of prospective science teachers in South Korea, where passing a high‐stakes, annual competitive examination is a prerequisite for ...

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

Sustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

Dynamic Pressure Simulation of an External Gear Pump With Relief Chamber Using a Morphological Approach

IEEE Access, 2018
During the working cycle of an external gear pump, hydraulic oil trapped between the pair of meshing gear and pinon teeth may exert high-pressure pulses due to periodic volumetric compression and expansion of the trapped volume. The pressure pulses cause
