This paper describes an interdisciplinary humanitarian project initiated by the Electrical Engineering Department at Arkansas Tech University.The project goal was to provide solar powered computers to disadvantaged students in areas where resources were not available for them to otherwise have computer access.It also incorporates environmental aspects of recycling old laptop computers and powering them with

To engage students in active learning of discrete convolution, a Jupyter notebook was generated and shared with students in the Signals & Systems course.Discrete convolution operation and its properties along with two general examples, medication administration, and the statistical probability density distributions, are presented in this paper.The examples were chosen to be different from standard examples in textbooks so that students would appreciate the application of convolution to other areas.The notebook provided a mathematical and visual explanation of the convolution operation.Python codes were developed, and their results were embedded in the Jupyter notebook.The students were encouraged to modify and rerun the codes in real-time.The notebook environment provides an excellent opportunity for them to learn and validate their understanding of the basic concepts of discrete convolution.Students received credit for using the notebook and answering survey questions anonymously.Results showed that students found that this Jupyter notebook was effective in helping them understand discrete convolution and its properties.

The recent debate in Congress and the Senate about diversification at the Federal Reserve spurred the growth of research on this subject.Studies on diversity in the Federal Reserve, especially the FOMC, analyze the gender composition of Boards of Governors of regional Federal Reserve banks and voting patterns for males vs. females.However, there is a critical question that no study has chosen to address, which is: Does it matter to investors whether FOMC members are males or females?This study finds that females within the Federal Reserve generally have a greater significant impact on market volatility when communicating in public.However, when considering the rank of Chairman, a male Chairman has a greater significant impact on market volatility than a female Chairman.
