Constructing an 'industry': the case of industrial gases, 1886–2006

Historically minded social scientists who analyse business and industrial development over time – including business historians – often deploy the term ‘industry’ as if its meaning were both self-evident and unchanging through time. This article uses the case of the international industrial gases industry over the course of 12 decades to demonstrate some ways in which a more critical and dynamic view of ‘industry’ – in combination with recognition of the imperfect overlap between firms on the one hand and industries on the other – enables better understanding and analysis of both

The Realities of Being a Part-time ESL Teacher

In an attempt to describe the position of a part-time ESL teacher in a secondary school, this paper explores what is involved. The components of teaching as well as the components of learning are discussed. The paper also addresses issues faced by part-time ESL teachers and administrators and presents suggestions on how to cope with these issues

Comparing Pineapples with Lilikois: An Experimental Analysis of the Effects of Idea Similarity on Evaluation Performance in Innovation Contests

Identifying promising ideas from large innovation contests is challenging. Evaluators do not perform well when selecting the best ideas from large idea pools as their information processing capabilities are limited. Therefore, it seems reasonable to let crowds evaluate subsets of ideas to distribute efforts among the many. One meaningful approach to subset creation is to draw ideas into subsets according to their similarity. Whether evaluation based on subsets of similar ideas is better than compared to subsets of random ideas is unclear. We employ experimental methods with 66 crowd workers to explore the effects of idea similarity on evaluation performance and cognitive demand. Our study contributes to the understanding of idea selection by providing empirical evidence that crowd workers presented with subsets of similar ideas experience lower cognitive effort and achieve higher elimination accuracy than crowd workers presented with subsets of random ideas. Implications for research and practice are discussed

Krozenbomen: goed nieuws voor bijen

Vroeger stonden in het rivierengebied en in Zeeland op wel haast elk erf een of meer krozenbomen. Ook waren er tot de jaren 70 van de vorige eeuw nog verschillende krozenboomgaarden en werden krozen in windsingels en erfbeplantingen opgenomen. Om verschillende, vaak economische, redenen zijn in de afgelopen jaren veel krozenbomen gerooid en vervangen door andere bomen. Inmiddels is de kroos begonnen aan een terugkeer, hetgeen goed is voor milieu, natuur en landschap. En dat is ook goed nieuws voor imkers en hun bijen

Identification and evaluation of fluvial-dominated deltaic (Class I oil) reservoirs in Oklahoma. Final report, August 1998

The Oklahoma Geological Survey (OGS), the Geo Information Systems department, and the School of Petroleum and Geological Engineering at the University of Oklahoma have engaged in a five-year program to identify and address Oklahoma`s oil recovery opportunities in fluvial-dominated deltaic (FDD) reservoirs. This program included a systematic and comprehensive collection and evaluation of information on all FDD oil reservoirs in Oklahoma and the recovery technologies that have been (or could be) applied to those reservoirs with commercial success. The execution of this project was approached in phases. The first phase began in January, 1993 and consisted of planning, play identification and analysis, data acquisition, database development, and computer systems design. By the middle of 1994, many of these tasks were completed or nearly finished including the identification of all FDD reservoirs in Oklahoma, data collection, and defining play boundaries. By early 1995, a preliminary workshop schedule had been developed for project implementation and technology transfer activities. Later in 1995, the play workshop and publication series was initiated with the Morrow and the Booch plays. Concurrent with the initiation of the workshop series was the opening of a computer user lab that was developed for use by the petroleum industry. Industry response to the facility initially was slow, but after the first year lab usage began to increase and is sustaining. The remaining six play workshops were completed through 1996 and 1997, with the project ending on December 31, 1997
