It analyses how a design changes through the conception, installation and use stages and how this introduces activities which cross the boundary of safe behaviour, but are tolerated by the users as effective ways of meeting production and other goals.
The history of the first programmable electronic computer, from its conception, construction, and use to its afterlife as a part of computing folklore.
Time is a social construct whose heterogeneous character is reflected well in the multiplicities of its models, conceptions and uses across different social, cultural, situational, historical and economic contexts (Birth 1999, 2004, 2013; Duncheon and Tierney 2013; Pronovost 1986).
These possibilities could be investigated in future studies by varying the dietary components, the timing for dietary intervention (pre- or post-conception) and using different genetic backgrounds with different susceptibility to hyperglycaemia or obesity.
The new boundaries around malls and housing estates, protected by barbed wire and a burgeoning private-security industry, have changed conceptions and uses of public space, fragmenting the tissue of the city and weakening its original centralized structure around a public core.
More importantly, however, rather than protecting our participants or safeguarding their interests, this requirement introduced specific ethical and practical challenges in the fieldwork through enforcing (even if indirectly) Western conceptions and uses of 'time' within 'the field' and prolonging the recruitment and data collection processes for the researcher.
Some authors favor performance of transabdominal cerclage before conception, and the use of laparoscopic technique [ 11] has the advantages of minimally invasive surgery.
Khoury et al, 1988, found that 20% of mothers moved between conception and delivery using data from the Maryland Birth Defects Reporting and Information System in 1984 [ 12].
Another approach is to construct a new, broad conception of biological information and use this conception to show that the informational role of genes is not exclusive (Jablonka 2002).
As context for these studies and for further discussion of the literature on assessing students' conceptions and the use of concept inventories, please see the following: Klymkowsky, M. W., and Garvin-Doxas, K. (2008).
