Desirable grain quality attributes vary depending upon the intended end use of grain. Environment, production practices and genetics are all of importance. Nutritional value of grain is most important for animal feed. Dry mill and alkaline cooked products require hard kernels with low breakage susceptibility and high protein concentration. Grain for these uses would best be produced under dryla...

In 1978, a group of researchers led by Dave Parnas developed a tabular nota-tion for specifying software requirements called SCR (Software Cost Reduction)and used the notation to specify the requirements of a mission-critical program,the Operational Flight Program for the A-7 aircraft. Since then, the require-ments of many critical programs, including control software for nuclea...

There have been many published studies aiming to identify temporal changes in river flow time series, most of which use monotonic trend tests such as the Mann–Kendall test. Although robust to both the distribution of the data and incomplete records, these tests have important limitations and provide no information as to whether a change in variability mirrors a change in magnitude. This study d...

Despite their impor tance in assess ing the impact of pol i cies, out come eval u a tions—and in par tic u lar ran dom ized exper i ments—are rel a tively rare. The ratio nal iza tions used to jus tify the absence of out come eval u a tions include such asser tions as “we know our pro grams are work ing,” “they can’t pos si bly harm any one,” and “if they only help one kid they’re worth it.” Us...
