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 ...

Analysis of Dynamics Characteristic of the Helical Gear Transmission in Helicopter

Jixie chuandong, 2015
The multiaxial helical gear transmission is widely used in helicopter for parallel operation. The dynamics model of the helical gear transmission is established for system inherent characteristic analysis,and the dynamic response is obtained.

Spontaneous unidirectional rotation of a symmetric gear driven by spherical active particles

National Science Open
Time reversal asymmetry and spatial anisotropy are considered two prerequisites for Brownian ratchet. An intriguing realization can be achieved by placing an asymmetric gear in the suspension of motile rod-like bacteria.

Reshaping Labor Intermediation: An Integrated Workforce Management Strategy to Contrast Agricultural Workers' Exploitation in Italy

Strategic Change, EarlyView.
ABSTRACT Labor exploitation within agri‐food supply chains poses significant ethical and managerial challenges, particularly in Mediterranean contexts where irregular employment practices persist. This study investigates the case of NoCap, a third‐party ethical certification initiative operating in Italy that integrates social responsibility into ...

INVESTIGATION OF GEARS WITH ASYMMETRIC PROFILE USING RELIABILITY PARAMETERS

Ukrainian Journal of Mechanical Engineering and Materials Science
The results of the study of gears with involute and sinusoidal teeth are presented herein. The subjects of the comparative analysis were the stresses at the root of the tooth from the side of the applied load and from the side of the unloaded profile, contact stresses, and elastic deformations under the action of a given torque.

C‐LENS: An Integrative Process Framework for Managing Governance and Complexity in University–Industry Collaboration

Knowledge and Process Management, EarlyView.
ABSTRACT University–industry collaboration (UIC) often underperforms not because its relevance is unclear, but because collaboration processes are rarely designed to accommodate evolving governance needs amid complexity. Existing studies have examined drivers, barriers, and institutional interfaces, yet process dynamics, governance mechanisms, and ...

Should Paratonia Be Considered a Movement Disorder? Implications for Clinical Management

Movement Disorders Clinical Practice, EarlyView.
Abstract Paratonia is an involuntary and variable resistance to passive movement that emerges with cognitive decline in dementias of different etiologies, with prevalence approaching 90% to 100% in end‐stage disease. It is common in Parkinson disease and the atypical parkinsonisms.

Parametric Modeling and Contact Stress Analysis of Asymmetric Modified Helical Gears

Jixie chuandong
In order to construct an accurate model of asymmetric involute modified helical gears and analyze the influence of pressure angles on its contact stress, based on the gear meshing principle and the secondary development of SolidWorks in C#, a ...

A framework for investigating fish population density responses to habitat fragmentation

Oikos, EarlyView.
Globally, fish populations that rely on rivers are being fragmented by in‐stream barriers, but it is unclear how pervasive any negative population responses to fragmentation are. We developed a modeling framework for estimating density responses of fishes upstream and downstream of in‐stream barriers and applied it to learn how low‐head dams have ...

Participatory mapping and Nature's Contributions to People: Insights from the Amazon Delta

People and Nature, EarlyView.
Abstract Understanding how traditional and coastal communities perceive and interact with nature is key to promoting inclusive conservation. This article examines human–nature interaction in the fishing village of Jubim, located in the Marajó Archipelago, delta of the Amazon River, Brazil.
