Where Projects Fail: Geospatial Evidence of Delays and Cancellations in Chinese Development Finance
Journal of International Development, EarlyView.ABSTRACT Delays and cancellations can severely undermine the effectiveness of development finance. Yet, little systematic evidence exists on where and why these disruptions occur within the rapidly expanding portfolio of Chinese‐financed development projects in Africa.

Determinants of Early Renal Function Recovery After TIPS in Patients With Portal Hypertension
The Kaohsiung Journal of Medical Sciences, EarlyView.ABSTRACT Renal dysfunction frequently occurs in patients with portal hypertension and is linked to unfavorable clinical outcomes. Transjugular intrahepatic portosystemic shunt (TIPS) has the potential to enhance renal perfusion through portal decompression; however, factors predicting early improvement in renal function remain insufficiently defined ...
