With great power comes great responsibility: How narrow conceptions of validity in high‐stakes testing undermine competence

Medical Education, EarlyView.
Abstract Context As Medical Education recognises the 100th anniversary of Kelley's writing on validity, ongoing efforts to implement competency‐focused training make the centenary a critical time to reflect on the sufficiency of validity argumentation for high‐stakes testing.

The Form of Agency

Noûs, EarlyView.
ABSTRACT Philosophers often think agency is essentially connected with rationality, intention, or control. However, Minimalists argue that agency is just the power to cause a change; acids and boulders are agents too. Many philosophers treat Minimalism as a wild outlier, assuming its falsity without argument.

A Study on a Speed Regulation Method for Mining Scraper Conveyors and a Control Strategy for Permanent Magnet Drive Systems

Actuators
To address the mismatch between materials and operational speed in mine scraper conveyors under time-varying load conditions, this paper proposes a methodology for the regulation of speed based on the quantity of coal transported by the scraper conveyor.

Vibration characteristics research of the polygonal effect of scraper conveyor

IOP Conference Series: Materials Science and Engineering, 2019
Abstract This article mainly studies the chain of scraper conveyor and analyzes the dynamic characteristics of the chain in the condition of load and load free. Numerical simulation, including the speed of movement and the simulation of chain tension, is used to simulate the special points of scraper conveyor chain.

Physical and chemical characterization of recycled glass sand for environmental restoration

Restoration Ecology, EarlyView.
Abstract Introduction We rely on coastal resources for food, water, and energy. However, over 75% of U.S. coastlines are eroding. Concurrently, the U.S. recycles less glass than other developed countries, landfilling hundreds of millions of tons every year.

STUDY ON MECHANICAL CHARACTERISTICS OF SCRAPER CONVEYOR UNDER CHAIN-BREAKING CONDITION

Jixie qiangdu, 2022
Abstact Taking into account the long-distance and heavy-duty working characteristics of the scraper conveyor, the harsh working environment and complex working conditions often lead to jams and chain broken accidents.
