What ETFs/funds to invest in when short-term rates are dropping, long-term rates rising?

This seems to be happening and maybe continuing into the foreseeable future: Governments' debt growing, and other issues pushing long-term interest rates up as their borrowing costs increase. Meanwhile, a weakening economy (so far visible in lack of hiring) causing short-term rates to go lower. If I have some cash to allocate towards investing in an ETF or mutual fund to gain from that, what are some ideas?
