The “Ought-Is” Problem: An Implementation Science Framework for Translating Ethical Norms Into Practice

Abstract

We argue that once a normative claim is developed, there is an imperative to effect changes based on this norm. As such, ethicists should adopt an “implementation mindset” when formulating norms, and collaborate with others who have the expertise needed to implement policies and practices. To guide this translation of norms into practice, we propose a framework that incorporates implementation science into ethics. Implementation science is a discipline dedicated to supporting the sustained enactment of interventions. We further argue that implementation principles should be integrated into the development of specific normative claims as well as the enactment of these norms. Ethicists formulating a specific norm should consider whether that norm can feasibly be enacted because the resultant specific norm will directly affect the types of interventions subsequently developed. To inform this argument, we will describe the fundamental principles of implementation science, using informed consent to research participation as an illustration.     

Human Odometry with a Two-Legged Hopping Gait: A Test of the Gait Symmetry Theory

Abstract

Biological odometry refers to the capacity for perceptually measuring distances traveled during locomotion. In the case of haptic odometry, information about distance traversed is generated from the movements of the legs, with coordinated leg motions (i.e., gait patterns) producing patterns of tissue deformation detectable by the haptic perceptual system. The gait symmetry theory of haptic odometry classifies gaits based upon the symmetry of muscle activation patterns. This classification identifies candidate higher-order variables of haptic odometry and provides a promising basis for understanding the associated patterns of tissue deformation detected by the haptic perceptual system. The theory successfully predicts biases (i.e., underestimations/overestimations) resulting from the manipulation of the gait patterns used in the outbound and return phases of homing tasks. We test gait symmetry theory by considering a previously unexamined key prediction. Two-legged hopping and walking have the same symmetry group classification, therefore, a homing task completed using any combination of two-legged hopping and walking as the outbound/return gaits should produce no systematic biases. Contrary to this prediction we observed systematic biases. We discuss the possibilities for modifying gait symmetry theory to account for our findings, and we present a new alternative theory based upon spatial reference frames.
