Abstract

A magnetorheological knee prosthesis is presented that automatically adapts knee damping to the gait of the amputee using only local sensing of knee force, torque, and position. To assess the clinical effects of the user‐adaptive knee prosthesis, kinematic gait data were collected on four unilateral trans‐femoral amputees. Using the user‐adaptive knee and a conventional, non‐adaptive knee, gait kinematics were evaluated on both affected and unaffected sides. Results were compared to the kinematics of 12 age, weight and height matched normals. We find that the user‐adaptive knee successfully controls early stance damping, enabling amputee to undergo biologically‐realistic, early stance knee flexion. These results indicate that a user‐adaptive control scheme and local mechanical sensing are all that is required for amputees to walk with an increased level of biological realism compared to mechanically passive prosthetic systems.

Abstract

Purpose

Research on conflict mediation presents a scattered, piecemeal understanding of what determines mediators’ strategies and tactics and ultimately what constitutes successful mediation. This paper presents research on developing a unifying framework – the situated model of mediation – that identifies and integrates the most basic dimensions of mediation situations. These dimensions combine to determine differences in mediator’s strategies that in turn influence mediation processes and outcomes.

Design/methodology/approach

The approach used by this paper was twofold. First, the existing empirical literature was reviewed on factors that influence mediator’s behaviors. Based on the findings of this review, a survey study was conducted with experienced mediators to determine the most fundamental dimensions of mediation situations affecting mediators’ behaviors and mediation processes and outcomes. The data were analyzed through exploratory factor analysis and regression analysis.

Findings

The results of the study show that four of the most fundamental dimensions of mediation situations include: low vs high intensity of the conflict, cooperative vs competitive relationship between the parties, tight vs flexible context and overt vs covert processes and issues. Each of these factors was found to independently predict differences in mediators’ behaviors and perceptions of processes and outcomes. These dimensions are then combined to constitute the basic dimensions of the situated model of mediation.

Originality/value

The situated model of mediation is both heuristic and generative, and it shows how a minimal number of factors are sufficient to capture the complexity of conflict mediation in a wide range of contexts.

Abstract

Purpose

Conventional wisdom tells us that mediation without ripeness is a fool’s errand (Zartman and Touval, 1985). What, then, is Türkiye’s motivation for mediating the war in Ukraine in lieu of ripeness – and what can its behavior as a mediator tell us about that motivation? In pursuit of this question, this paper inductively analyzes Turkish mediation in the Ukraine war to unpack the relationship between a contextual (ripeness) and actor-level (motivation) variable. Of particular interest is the decision-making and behavior of third parties (like Türkiye in Ukraine) who elect to mediate highly complex conflicts in which ripeness is indiscernible. The purpose of this research is not to propose or test a causal relationship between obscured ripeness and mediation, but rather to examine mediation behavior in situations where ripeness is obscured.

Design/methodology/approach

The impact of weaponized information on ripeness and third-party mediation is evaluated through an original, systematic and inductive case study analysis of Turkish mediation in the Russia–Ukraine war. As an intense theater of operations for information warfare for well over a decade, the war in Ukraine serves as an especially apt choice for an analysis of “obscured ripeness.” Likewise, Türkiye’s anomalous position as the only substantive source of mediation in the conflict lends significance to an empirical examination of its motivation and behavior as a mediator.

Findings

This research reveals that the pervasive use of weaponized information in the Russia–Ukraine war has distorted and disordered the information environment, thereby obscuring the ability of third parties to determine if the conflict is or could be ripe for mediation. However, the condition of obscured ripeness that prevails in the conflict has not proven a deterrent for mediation by Türkiye, which, as the only mediator in the conflict, has used a transactional approach to mediation motivated by self-regarding interests and animated by a manipulative mediation strategy. In sum, this inductive analysis of Turkish mediation in Ukraine reveals that the use of weaponized information in a conflict indirectly selects on transactional mediation (and mediators). The significance of this finding is magnified by the widespread use of weaponized information in contemporary conflicts as well as the declining frequency of third-party mediation.

Originality/value

There have been few, if any, systematic assessments in Turkish mediation of the Russia–Ukraine war, and none specifically concerned with the effects of weaponized information. Additionally, the paper proposes a typology of mediator motivation that is used to structure that assessment, while also introducing a new concept (“obscured ripeness”) and linking that concept both to the existing literature on ripeness and to the use of weaponized information in contemporary armed conflicts. As such, this manuscript represents an important contribution both to the empirical and theoretical landscape with respect to the study of mediation and international conflict management.
