Given the context of many institutions moving to online instruction due COVID-19 pandemic in 2020, we share our experiences an team-based multidisciplinary education program on big data + high performance computing (HPC) atmospheric sciences (cybertraining.umbc.edu). This focuses how apply and high-performance techniques sciences. The uses both instructional phase with lectures homework all thr...

We propose a consolidated risk measure based on variance and the safety-first principle in a mean-risk portfolio optimization framework. The safety-first principle to financial portfolio selection strategy is modified and improved. Our proposed models are subjected to norm regularization to seek near-optimal stable and sparse portfolios. We compare the cumulative wealth of our preferred propose...

We analyze dynamic portfolio choice problems using an approximate dynamic programming (ADP) algorithm. We extend the algorithm to the case of constraints on borrowing and implement a duality-based simulation procedure for estimating bounds on the true value function. We demonstrate that the ADP solution exhibits a high degree of accuracy in the considered examples, indicating that this is a pro...

Many portfolio managers measure performance with reference to a benchmark. The difference in return between a portfolio and its benchmark is the active return of the portfolio. Portfolio managers and their clients want to know what caused this active return. Performance attribution decomposes the active return. The two most common approaches are the Brinson-Hood-Beebower (hereafter referred to ...

The purpose of the study was to examine the effects of two instructional approaches designed to improve the reading fluency of 2nd-grade children. The first approach was based on Stahl and Heubach's (2005) fluency-oriented reading instruction (FORI) and involved the scaffolded, repeated reading of grade-level texts over the course of each week. The second was a wide-reading approach that also i...

This paper considers a multi-objective portfolio selection problem imposed by gaining of portfolio, divided yield and risk control in an ambiguous investment environment, in which the return and risk are characterized by probabilistic numbers. Based on the theory of possibility, a new multi-objective portfolio optimization model with gaining of portfolio, divided yield and risk control is propo...
