Paradoxical tensions in exploiting data to implement circular economy in the textile industry.

Increasing utilization of data, enabled by digitalization, constitutes a major driver toward circular economy but is not without potential paradoxical tensions. A two-round disaggregative Delphi study and analysis of the qualitative material generated in it explored these tensions. They were found to cohere around three themes: consumer concurrence, business transparency, and technology relevance.

Paradoxical Tensions Related to AI-Powered Evaluation Systems in Competitive Sports.

Judging in competitive sports is prone to errors arising from the inherent limitations to humans' cognitive and sensorial capabilities and from various potential sources of bias that influence judges. Artistic gymnastics offers a case in point: given the complexity of scoring and the ever-increasing speed of athletes' performance, systems powered by artificial intelligence (AI) seem to promise benefits for the judging process and its outcomes. To characterize today's human judging process for artistic gymnastics and examine contrasts against an AI-powered system currently being introduced in this context, an in-depth case study analyzed interview data from various stakeholder groups (judges, gymnasts, coaches, federations, technology providers, and fans).

Cardiovascular stress in isokinetic trunk strength test.

Study Design: In this experimental study, the participants served as their own controls.

Objective: To estimate cardiovascular stress in isokinetic trunk extension-flexion strength test.

Summary Of Background Data: Thirty-one women with low back or neck pain who participated in the physical reconditioning program were the study participants.

Paradoxical variation of strength determinants with different rotation axes in trunk flexion and extension strength tests.

The aim of this study was to illustrate the influence of different levels of the fulcrum (the axis of sagittal rotation) on measured trunk flexion and extension strength and compare force and torque as a unit of measure. The isometric trunk strength was measured in 16 healthy female subjects. The dynamometer was kept at the shoulder level and the moment arm was lengthened step by step by moving the fulcrum caudally from the level of the posterior superior iliac spine to the level of the gluteal fold.
