Existing studies have examined the impact of inward foreign direct investment (IFDI) on venture creation mainly at the country level. Now, an international team, including a researcher from Waseda University, has explored the multifaceted effects of IFDI on new venture creation at the industry-regional level, proposing an inverted U-shaped effect driven by learning opportunities and competitive threats. These insights can help local governments calibrate IFDI inflows to maintain a productivity-enhancing balance.

This paper proposes a new power generating system that combines wind power (WP), photovoltaic (PV), trough concentrating solar power (CSP) with a supercritical carbon dioxide (S-CO₂) Brayton power cycle, a thermal energy storage (TES), and an electric heater (EH) subsystem. The wind power/photovoltaic/concentrating solar power (WP–PV–CSP) with the S-CO₂ Brayton cycle system is powered by renewable energy. Then, it constructs a bi-level capacity-operation collaborative optimization model and proposes a non-dominated sorting genetic algorithm-II (NSGA-II) nested linear programming (LP) algorithm to solve this optimization problem, aiming to obtain a set of optimal capacity configurations that balance carbon emissions, economics, and operation scheduling. Afterwards, using Zhangbei area, a place in China which has significant wind and solar energy resources as a practical application case, it utilizes a bi-level optimization model to improve the capacity and annual load scheduling of the system. Finally, it establishes three reference systems to compare the annual operating characteristics of the WP–PV–CSP (S-CO2) system, highlighting the benefits of adopting the S-CO₂ Brayton cycle and equipping the system with EH. After capacity-operation collaborative optimization, the levelized cost of energy (LCOE) and carbon emissions of the WP–PV–CSP (S-CO₂) system are decreased by 3.43% and 92.13%, respectively, compared to the reference system without optimization.

As Congress debates the future of telehealth coverage under Medicare, a study shows that it hasn’t led to an increase in total visits since 2020, but different medical specialties, especially mental health, have different rates of use.

In a world facing rising economic uncertainty and instability, look to cross-border investment activity for solid clues about what's next for economic growth and foreign exchange rates.

 

That's a key finding by Steven Riddiough, an associate professor of finance at the University of Toronto Scarborough and Rotman School of Management, and Huizhong Zhang from Australia's Monash University. They assessed nearly a quarter century of data on cross-border deals involving more than 40 countries and identified a predictive relationship between changes in a country's foreign investment activity and future changes in its economic growth and currency values.
