4	Measurement and analysis of construction labour productivity Talhouni, Bassam T. K. January 1990 (has links) An analytical approach for explaining the variability in labour intensive construction operations has been developed. A consistent method of collecting productivity developed jointly at the Pennsylvania State University and the University of Dundee has been refined and tested. Data has been collected daily from seven Scottish sites for continuous periods of up to 3 months. Not only productivity but many of the factors affecting it have been measured. A comprehensive, computerised database has been designed to facilitate data storage and manipulation. The quantification of the impact of each individual factor is based on the assumption that deviations from an operative?s normal output arise because of disturbances imposed by a multiplicity of site factors. The impact of each individual factor causes the average daily productivity to change. 658
5	Comparing Genetic Modification and Genetic Editing Technolgies: Minimal Required Acreage Neadeau, Joseph Francis January 2018 (has links) There are many technologies being developed for crop breeding. Two interesting technologies are genetic modification and genetic editing. Competitive pressures and changing consumer preferences are forcing organizations to invest heavily in these two technologies. Organizations must decide which traits they want to target and must commit significant time a money to the project. Traditionally, firms would decide which project to embark on if the project is net present value positive. Throughout the research and development process managers have flexibility to abandon the project once new information is received. That flexibility has value and real option analysis must be performed to value that flexibility. Once the value of a GM and GE project is determined, how might an organization decide which project to do? The concept of minimum required acreage (MRA) is developed in this study, allowing organizations to compare GM and GE technologies and decide which project to invest it. Crops -- Genetic engineering.
