Past automation research has focused primarily on machine-related factors (e.g., automation reliability) and human-related factors (e.g., accountability). Other machine-related factors such as type of automation errors, misses or false alarms, have been noticeably overlooked. These two automation errors correspond to potential operator errors, omission (misses) and commission (false alarms), which have proven to directly affect operators' trust in automation. This proposed research will examine how automation-error-type affects operator trust and begin to develop baseline trust measures as they relate to error type and participant age. It is expected that participants presented with more automation false alarms than misses will experience a larger degradation of subjective trust than those presented with equal numbers of false alarms and misses or more automation misses than false alarms.

Short- to mid-term results of a prospective study evaluating dual intramuscular and intra-arterial autologous bone-marrow mononuclear cell (BM-MNC) implantation for the treatment of patients with severe peripheral arterial occlusive disease (PAD) in whom amputation was considered the only viable treatment option are presented. Ankle-brachial indices (ABIs), rest pain, and ulcer healing were assessed at 3 months. Success was defined as improvement in ABI measurements; absence of rest pain; absence of ulcers; and absence of major limb amputations. Twenty patients (21 limbs) have been enrolled. Three-month follow-up evaluation accounting included 18 patients (19 limbs). Four (22.2%) major and 2 (11.1%) minor amputations were performed within 3 months postoperatively. With 17 (94.4%) of 18 limbs demonstrating at least one criterion for success and major amputation avoided in 14 (77.8%) of 18 limbs at the 3-month evaluation, this specific BM-MNC implantation technique is an effective limb salvage strategy for patients with severe PAD.

The United Arab Emirates' vision of the 2021 National agenda aimed that its students rank among the best in the world in mathematics and the sciences. However, fractions remain a challenging topic for both teachers and students. The purpose of this study was to investigate the impact of using digital games-based learning (ABACUS) on students' performance as they learn fractions. A quasi-experimental design was used in carrying out the research. All groups were pre-and posttested to evaluate the effectiveness of the ABACUS active learning intervention. Eighty (n=80) student participants were divided randomly into a control (n=39) group and an experimental (n=41) group. Descriptive and inferential statistics were used to analyze the data from the preand post-tests. The results suggested that students in the post-test of the experimental group achieved a higher score than those in the control group. The findings of this study may provide mathematics teachers with an alternative method to teaching the concept of fractions. Additionally, the findings may also inspire or encourage curriculum planners to integrate digital games-based learning in educational settings. The study concluded with some implications and recommendations for future research.
