From Custom to Court: The Evolution of Mediation in European Legal Systems

open access: yesConflict Resolution Quarterly, EarlyView.
ABSTRACT This article traces how European mediation has repeatedly rebalanced three variables—(1) the source of mediator authority, (2) the degree of institutionalization, and (3) the operative meaning of voluntariness—from antiquity to the present. Using three periods—Proto‐Mediation (c. 500 BCE–c. 1750), Classical Mediation (c.

Uniaxial compressive strength prediction and ratio parameter optimization of titanium tailings composite backfill materials using intelligent hybrid models

open access: yesDeep Underground Science and Engineering, EarlyView.
Based on the 90 datasets, ERT and four optimization algorithms were used to build four hybrid models to predict the UCS of the backfill body. The SMA‐ERT model was the most effective model, and it can reliably guide the design of the backfill ratio parameters. Abstract This study analyzed the feasibility of using titanium (Ti) tailings as a backfilling
