Methodological Pluralism and the Possibilities and Limits of Interviewing

Against the background of recent methodological debates pitting ethnography against interviewing, this paper offers a defense of the latter and argues for methodological pluralism and pragmatism and against methodological tribalism. Drawing on our own work and on other sources, we discuss some of the strengths and weaknesses of interviewing. We argue that concern over whether attitudes correspond to behavior is an overly narrow and misguided question. Instead we offer that we should instead consider what interviewing and other data gathering techniques are best suited for. In our own work, we suggest, we have used somewhat unusual interviewing techniques to reveal how institutional systems and the construction of social categories, boundaries, and status hierarchies organize social experience. We also point to new methodological challenges, particularly concerning the incorporation of historical and institutional dimensions into interview-based studies. We finally describe fruitful directions for future research, which may result in methodological advances while bringing together the strengths of various data collection techniques. © 2014 Springer Science+Business Media New York

Short Sale Constraints and Stock Returns

Stocks can be overpriced when short sale constraints bind. We study the costs of short selling equities, 1926-1933, using the publicly observable market for borrowing stock. Some stocks are sometimes expensive to short, and it appears that stocks enter the borrowing market when shorting demand is high. We find that stocks that are expensive to short or which enter the borrowing market have high valuations and low subsequent returns, consistent with the overpricing hypothesis. Size-adjusted returns are one to two percent lower per month for new entrants, and despite high costs it is profitable to short them.

Airborne aerosol lidar

The objectives are: to analyze dual polarization lidar measurements of aerosols and polar stratospheric clouds (PSCs) obtained aboard the NASA Ames DC-8 aircraft during the 1989 Airborne Arctic Stratospheric Expedition (AASE); and to combine lidar, SAM II, and other AASE data with theoretical modeling calculations to study PSC characteristics. A summary of progress and results is given

What constitutes a good control system for operations?

The requirements that operations have of a control system are enumerated without reference to implementation. Examples from the SPS and LEP are used to illustrate possible solutions and pitfalls. The key constituents of a control system from an operational viewpoint are then highlighted. Some suggestions about how they might be provided are discussed in the conclusion
