I am planning my next year’s research agenda.

I have identified a number of interesting topics to work on, for which I’d appreciate your input: how would you vote for, in order of priority, given the following titles?
a> Transaction Banking for regional banks
b> Strategies for Trade Finance
c> Processes, People, and Technology in Transaction Banking
d> Status of electronic invoicing
e> Demistifying TSU
f> Procurement and Finance: the two sides of the working capital optimization equation
g> Cash advisory services from banks
h> State-sponsored supply chain finance programs
i> The ROI of interoperability

Happyo to provide more information/ clarification where needed.
