Where does good evidence come from?

This paper started as a debate between the two authors. Both authors present a series of propositions about quality standards in education research. Cook’s propositions, as might be expected, concern the importance of experimental trials for establishing the security of causal evidence, but they also include some important practical and acceptable alternatives such as regression discontinuity analysis. Gorard’s propositions, again as might be expected, tend to place experimental trials within a larger mixed method sequence of research activities, treating them as important but without giving them primacy. The paper concludes with a synthesis of these ideas, summarising the many areas of agreement and clarifying the few areas of disagreement. The latter include what proportion of available research funds should be devoted to trials, how urgent the need for more trials is, and whether the call for more truly mixed methods work requires a major shift in the community

Interest rate expectations and the slope of the money market yield curve

An examination of the relationship between yield and maturity in the money market. The expectations theory suggests that the yield curve should be a good predictor of future spot interest rates. A substantial body of research in recent years has tested this implication of the theory and discussed possible reasons for the lack of support for the theory from these tests. This paper provides a review of this literature.Interest rates

Placer mining in Alaska II

During July, August and September, 1979, a team from the Mineral Industry Research Laboratory visited a number of placer mining districts that could be reached by automobile, hence at a reasonable cost for transportation. These districts yielded varying amounts of information that will be of value to the industry. The district visited were: 1. Fairbanks, 2. Circle (Birch Creak), 3. Livengood (Tolovana), 4. Manley Hot Springs, 5. Fortymile, 6. Klondike, 7. Kantishna, 8.

Acquiring standard spoken English through extensive reading : a case study

An immigrant, who worked in an American machine shop, acquired polite standard spoken English by reading romance novels in an 18-week adult extensive-reading ESL class. Fulltime employment in the machine shop and once-a-week class discussions provided the only places where the studentwasroutinely exposed to spoken English
