Purpose: To examine the impact of a timing change on pacing behavior and perceptions in a high-stakes multiple-choice examination.
Method: Two samples of standard-time examinees were analyzed: (1) 29,796 examinees that completed the examination prior to the timing change, and (2) 28,373 examinees that completed the examination after the change. Subgroups of examinees were identified and compared within and across samples with respect to perceptions, accuracy, and pacing.
Results: After the timing change, more examinees reported having sufficient time to complete examination sections; a small improvement in overall accuracy was observed, and there was a shift in the time-per-item strategy, though examinees continued to use more than the average amount of time available per item at the beginning of sections.
Conclusions: Examinees are more satisfied with the new timing constraints, although an effect due to the time limit continues to impact performance at the end of test sections.

Sea ice can profoundly influence photosynthetic organisms by altering subsurface irradiance, but it is susceptible to changes in the climate. The patterns and timing of sea ice cover can vary on a monthly to annual timescale in small sub-regions of the Western Antarctic Peninsula (WAP). During the latter part of the 20th century, sea ice coverage significantly decreased in the WAP, a trend that aligns with warming in this area.

Transformative change is needed across the food system to improve health and environmental outcomes. As food, nutrition, environmental and health data are generated beyond human scale, there is an opportunity for technological tools to support multifactorial, integrated, scalable approaches to address the complexities of dietary behaviour change. Responsible technology could act as a mechanistic conduit between research, policy, industry and society, enabling timely, informed decision making and action by all stakeholders across the food system.

Background: Today, in a wide variety of industries, grinding operations are an extremely important finishing process for obtaining precise dimensions and meeting strict requirements for roughness and shape accuracy. However, the constant wear of abrasive tools during grinding negatively affects the dimensional and surface conditions of the workpiece. Therefore, effective monitoring of the wear process during grinding operations helps to predict tool life, plan maintenance and ensure consistent product quality.

Victims of trauma were at a higher risk of developing thromboembolic complications, and thus various agents were used for prophylaxis. Multiple studies recommended holding these agents in the perioperative period to decrease the potential complications of additional bleeding, wound issues, hematoma etc.

Objective: To investigate how estimated glomerular filtration rate (eGFR) decline following sodium-glucose cotransporter-2 inhibitors (SGLT2i) initiation predicts long-term cardiorenal outcomes.
Methods: From 2016 to 2020, a longitudinal cohort of 4942 diabetic patients treated with SGLT2i were enrolled and followed until December 2021. Patients were categorized into mild (≤30%), moderate (>30%∼≤40%) and severe (>40%) decline groups by the maximal eGFR change between 2 to 12 weeks after SGLT2i treatment.
