This book focuses on methods of choice in program evaluation. Credible methods choice lies in the assumptions we make about the appropriateness and validity of selected methods and the validity of those assumptions. As evaluators make methodological decisions in various stages of the evaluation proc...
A major reason complex programs are so difficult to evaluate is that the assumptions that inspire them are poorly articulated. Stakeholders of such programs are often unclear about how the change process will unfold. Thus, it is so difficult to reasonably anticipate the early and midterm changes th...
This book focuses on assumptions underlying methods choice in program evaluation. Credible program evaluation extends beyond the accuracy of research designs to include arguments justifying the appropriateness of methods. An important part of this justification is explaining the assumptions made abo...
This book discusses the crucial place that assumptions hold in conceptualizing, implementing, and evaluating development programs. It suggests simple ways for stakeholders and evaluators to 1) examine their assumptions about program theory and environmental conditions and 2) develop and carry out ef...
This is perhaps the most complete, detailed and readable story of manned space-flight ever published. The text begins with the historical origins of the dream of walking on the Moon, covers the earliest Mercury and Gemini flights and then moves on to the end of the Apollo era. In readable, fascinati...

In 'Paving the Way for Apollo 11' David Harland explains the lure of the Moon to classical philosophers, astronomers, and geologists, and how NASA set out to investigate the Moon in preparation for a manned lunar landing mission. It focuses particularly on the Lunar Orbiter and Surveyor missions....

One of the wonderful aspects of the US Manned Spaceflight Program was the opportunity for people around the entire globe to participate in one of man's greatest adventures. As we laid out the plans for flying the first manned spaceflight program, it was obvious that we would require exten sive opera...

In April 1970, an oxygen tank exploded aboard the Apollo 13 spacecraft, crippling the Command Module and forcing the three astronauts to evacuate into the tiny Lunar Module. As they desperately drifted around the moon, a silent, invisible killer began to build up inside the cramped cabin: their own ...
