Reviewing March's vision

This paper reviews a remarkable experiment in organisation. At the centre of the story is James G. (Jim) March, one of the most influential scholars in management and organisation studies over the last half century. From 1954 to 1964, March was a leading member of the Graduate School of Administration (GSIA) at the Carnegie Institute of Technology, which was an extraordinary hotbed of ideas and research at that time. The group was led by Herbert Simon, a true polymath who is now recognised as a founding father of many scientific domains.

Annotated almanac, 1752

Almanac containing calendar pages with sporadic annotations of unidentified measurements and interleaved pages with short handwritten entries about Winthrop's daily activities, and astronomical and meteorological observations. The entries include personal notes about travel, the weather, vegetable planting, and the birth of Winthrop's fourth son James (March 28) and taking him to wet nurses (March 31 and August 31). Throughout the volume there are entries about the smallpox epidemic including statistics about the disease's affect in Boston and family inoculations. At the end of the volume, there is a bill of mortality for Charlestown for 1752 with a chart of deaths according to age ranges.

The lost experiment in exploration and exploitation

This paper focuses on James March’s 1991 article on ‘Exploration and Exploitation in Organizational Learning’, which is now the seventh most highly cited paper in management and organisation studies. March’s paper is based on a computer program that simulates the collective and individual learning of a group of fifty individuals. The largely forgotten story that this paper re-calls is the real-life experiment that March, in large part, designed and conducted when he was the new ‘boy Dean’ of the School of Social Sciences in the University of California at Irvine between 1964 and 1969. Taken together, both stories illuminate important moments in the history of organisation studies. The comparison suggests that March’s model, which was probably the first simulation of an organisation learning, also worked to constitute rather than model the phenomenon.

Nutrients and oxygen concentrations measured in water samples from the North Atlantic during the James Cook cruise JC087 in March 2013

Analysis for micro-molar concentrations of nitrate and nitrite, nitrite, phosphate, silicate and ammonia was undertaken on a SEAL Analytical UK Ltd, AA3 segmented flow autoanalyser following methods described by Kirkwood (1996). Samples were drawn from Niskin bottles on the CTD into 15ml polycarbonate centrifuge tubes and kept refrigerated at approximately 4oC until analysis, which generally commenced within 30 minutes. Overall 23 runs with 597 samples were analysed. This is a total of 502 CTD samples, 69 underway samples and 26 from other sources. An artificial seawater matrix (ASW) of 40g/litre sodium chloride was used as the inter-sample wash and standard matrix. The nutrient free status of this solution was checked by running Ocean Scientific International (OSI) low nutrient seawater (LNS) on every run. A single set of mixed standards were made up by diluting 5mM solutions made from weighed dried salts in 1litre of ASW into plastic 250ml volumetric flasks that had been cleaned by washing in MilliQ water (MQ). Data processing was undertaken using SEAL Analytical UK Ltd proprietary software (AACE 6.07) and was performed within a few hours of the run being finished. The sample time was 60 seconds and the wash time was 30 seconds. The lines were washed daily with wash solutions specific for each chemistry, but comprised of MQ, MQ and SDS, MQ and Triton-X, or MQ and Brij-35. Three times during the cruise the phosphate and silicate channels were washed with a weak sodium hypochlorite solution.

Turbulence measurements performed in the North Atlantic during the James Cook cruise JC087, March 2013

During the cruise the turbulence probe MSS050 was used for microstructure measurements. The profiler is produced by Sea and Sun Technology GmbH in co-operation with ISW Wassermesstechnik. The probe was equipped with 2 velocity microstructure shear sensors, a microstructure temperature sensor, standard CTD sensors for precision measurements, a vibration control sensor, a two component tilt sensor, a fluorescence sensor and surface detection sensor (SD) to indicate the water surface hit at rising measurements. The sampling rate for all sensors is 1024 samples per second, the resolution 16 bit. During the MSS measurements, the ship was moving with speed approx. 0.5-1.0 knots with respect to the water against the wind. In order to take into account the intermittent nature of marine turbulence, repeated MSS measurements were carried out in bursts of typically 10 profiles per station. The measurement interval was approximately 7 (10) min for a profile to 140 (200) dbar. During JC87 cruise 8 series of turbulence measurements were conducted. Fluorescence data was obtained on the 5 of them.

Carbon concentration and sinking velocity of particles measured during the James Cook cruise JC087, March 2013

Sinking organic particles were collected from the Porcupine Abyssal Plain in 2013. Collection was done using a marine snow catcher (MSC), which is essentially a large (95 L) settling column. The marine snow catcher is deployed to one depth, the water trapped inside and then brought to the surface and left to stand on deck for 2 hours during which time the particles settle down (or up) the MSC depending on their settling rate. The particles are then collected and due to position of collection from the snow catcher are determined as fast or slow sinking particles. Some fluxes are negative as they were positively buoyant and not sinking.
