The case helps students to understand the emerging concept of linear and circular economies. It facilitates to examine the implications of circular business models such as remanufacturing on operations management decisions. It also introduces them to the concept of total cost of ownership and impact of remanufacturing on reducing total cost of ownership. The cases help students to evaluate the challenges and opportunities of remanufacturing business in emerging economy like India. This case is among the first few cases on the application of circular economy principles in context of heavy-duty and off-road sector and the impact of these principles on product design and production planning and control decisions.

Procedural extensions of SQL have been in existence for many decades now. However, little is known about their magnitude of usage and their complexity in real-world workloads. Procedural code executing in a RDBMS is known to have inefficiencies and limitations; as a result there have been several efforts to address this problem. However, the lack of understanding of their use in real workloads makes it challenging to (a) motivate new work in this area, (b) identify research challenges and opportunities, and (c) demonstrate impact of novel work. We aim to address these challenges with our work. In this paper, we present the results of our in-depth analysis of thousands of stored procedures, user-defined functions and triggers taken from several real workloads. We introduce SQL-ProcBench , a benchmark for procedural workloads in RDBMSs. SQL-ProcBench has been created using the insights derived from our analysis, and thus represents real workloads. Using SQL-ProcBench, we present an experimental evaluation on several database engines to understand and identify research challenges and opportunities. We emphasize the need to work on these interesting and relevant problems, and encourage researchers to contribute to this area.

This chapter shares a brief history of the STEM to STEAM movement, shares two case descriptions drawn from the perspectives of leaders in two school districts in which schools adopted a STEAM focus, describes challenges and opportunities associated with implementation of a STEAM initiative, and proposes five features to consider when implementing models to becoming a STEAM-focused school or school district. The five features drawn from analysis of the two cases are intentional efforts by school districts to gain buy-in; adequate time for teacher learning and planning through authentic and relevant professional development; community connections, real-world and problem-based or project-based; mutual decision-making and support between teachers and administrators; and budget planning and allocation.

The 21st Century Cures Act encourages the Food and Drug Administration to consider “real-world evidence” in its regulation of the safety and efficacy of drugs and devices. Many have interpreted this mandate to focus on non-randomized observational research. However, we suggest that regulatory science must also move from rarefied academic hospitals to community-based settings, where the vast majority of patients in fact receive care in the fragmented U.S. healthcare system. This move is especially important if innovations are to reach, and be validated in, more diverse populations. A solution can be found in the 183 Practiced-Based Research Networks (“PBRN”), i.e., groups of primary care clinicians and practices in all 50 states working to improve clinical care and translate research findings into practice. This symposium contribution seeks to (1) describe some of the common shortcomings of clinical trials, (2) explore the opportunities and challenges posed by use of real-world evidence as a basis for drug and device regulation, (3) briefly describe the history and evolution of PBRNs, and (4) articulate the challenges and opportunities for using PBRNs to fulfill the 21st Century Cures Act mandate for real-world evidence.
