Dissipation of stop-and-go waves via control of autonomous vehicles: Field experiments

Abstract: Traffic waves are phenomena that emerge when the vehicular density exceeds a critical threshold. Considering the presence of increasingly automated vehicles in the traffic stream, a number of research activities have focused on the influence of automated vehicles on the bulk traffic flow. In the present article, we demonstrate experimentally that intelligent control of an autonomous vehicle is able to dampen stop-and-go waves that can arise even in the absence of geometric or lane changing triggers. Precisely, our experiments on a circular track with more than 20 vehicles show that traffic waves emerge consistently, and that they can be dampened by controlling the velocity of a single vehicle in the flow. We compare metrics for velocity, braking events, and fuel economy across experiments. These experimental findings suggest a paradigm shift in traffic management: flow control will be possible via a few mobile actuators (less than 5%) long before a majority of vehicles have autonomous capabilities.

The revised self‐leadership questionnaire: Testing a hierarchical factor structure for self‐leadership

Abstract: Despite the popularity and potential of self‐leadership strategies in modern organizations, no acceptably valid and reliable self‐leadership assessment scale has heretofore been developed. The present study tests the reliability and construct validity of a revised self‐leadership measurement scale created on the basis of existing measures of self‐leadership. Results from an exploratory factor analysis (EFA) demonstrate significantly better reliability and factor stability for the revised scale in comparison to existing instruments. Further, results from a confirmatory factor analysis (CFA) utilizing structural equation modeling techniques demonstrate superior fit for a higher order factor model of self‐leadership, thus providing evidence that the revised scale is measuring self‐leadership in a way that is harmonious with self‐leadership theory. Based on these results, the revised scale appears to be a reasonably reliable and valid instrument for the measurement of self‐leadership skills, behaviors, and cognitions. Implications for future empirical self‐leadership research are discussed.

Management of type 2 diabetes: evolving strategies for the treatment of patients with type 2 diabetes

Abstract: The prevalence of type 2 diabetes continues to increase at an alarming rate around the world, with even more people being affected by prediabetes. Although the pathogenesis and long-term complications of type 2 diabetes are fairly well known, its treatment has remained challenging, with only half of the patients achieving the recommended hemoglobin A1c target. This narrative review explores the pathogenetic rationale for the treatment of type 2 diabetes, with the view of fostering better understanding of the evolving treatment modalities. The diagnostic criteria including the role of hemoglobin A1c in the diagnosis of diabetes are discussed. Due attention is given to the different therapeutic maneuvers and their utility in the management of the diabetic patient. The evidence supporting the role of exercise, medical nutrition therapy, glucose monitoring, and antiobesity measures including pharmacotherapy and bariatric surgery is discussed. The controversial subject of optimum glycemic control in hospitalized and ambulatory patients is discussed in detail. An update of the available pharmacologic options for the management of type 2 diabetes is provided with particular emphasis on newer and emerging modalities. Special attention has been given to the initiation of insulin therapy in patients with type 2 diabetes, with explanation of the pathophysiologic basis for insulin therapy in the ambulatory diabetic patient. A review of the evidence supporting the efficacy of the different preventive measures is also provided.
