In order to evaluate the effects of different slope lengths (1, 2, 3, 4, and 5 m) and different vegetation coverage ratios (20%, 45%, 60%, and 90%) on the mechanisms of nutrient loss and runoff producing processes, we have conducted 14 simulated rainfall experiments. The results show that N and P loss are decided by the concentration and the runoff volume, but when the amounts of N and P in top...

Kabale is a mountainous district In this paper, a review is made of land degradation within the district Land degradation is due to population pressure on the land and poor traditional land use practices. Introduction Mountain environments are very fragile and delicate ecosystems. Intensification of land use caused by an increase in population can have profound effects on the system by disturbi...

Many theoretical bond pricing models predict that the credit yield curve facing risky bond issuers is downward sloping. Previous empirical research (Sarig and Warga (1989) and Fons (1994)) supports these models. Our study examines sets of bonds issued by the same firm with equal priority in the liability structure, but with different maturities, thus holding credit quality constant. We find, co...

We show that the martingale component in the long-term factorization of the stochastic discount factor due to Alvarez and Jermann (2005) and Hansen and Scheinkman (2009) is highly volatile, produces a downward-sloping term structure of bond Sharpe ratios, and implies that the long bond is far from growth optimality. In contrast, the long forward probabilities forecast an upward sloping term str...

Changes in nominal interest rates must be due to either movements in real interest rates, expected inflation, or the inflation risk premium. We develop a term structure model with regime switches, time-varying prices of risk, and inflation to identify these components of the nominal yield curve. We find that the unconditional real rate curve in the U.S. is fairly flat around 1.3%. In one real r...
