The cost to employers of limiting the catchment size from which they employ their staff. Viola Proctor.
Apartheid has left an urban legacy with excessive commuting distances for low income workers. Climate Change and Peak Oil will cause transport costs to rise. „Low carbon‟ solutions are not viable in developing cities such as Cape Town, where most workers already use public transport and it is …

Effects Of The Soil Properties On The Maximum Dry Density Obtained Fro
… soils is needed to improve its strength. In 1933 Proctor developed a laboratory compaction test to determine the maximum dry density of compacted soils, which can be used for specifications of field compaction. The Compaction of soils is influenced by many factors, the most common are the moisture …

The effects of trained and untrained proctors on student performance and satisfaction in a PSI course
… described by Keller (1968) is the use of proctors which permit immediate scoring, tutoring, and personal-social interactions. Recent research has indicated that immediate scoring may not be an essential proctor function. However, personal-social interactions and tutoring may affect student …

Carving out a sense of place: The making of the Marble Valley and the Marble City of Vermont
… paving the way for others, principally Redfield Proctor. With the help of his political, economic, and business connections, Proctor turned the company into the Vermont Marble Company, the largest marble company in the world. Bitter rivalries between cliques such as the old guard Clements and the …

Understanding the human behavioural factors behind online learners’ susceptibility to phishing attacks
… by depending on technical controls alone (Proctor, Schultz and Vu, 2009). Effective Information Security Awareness is key to protecting against Phishing (Chen, Shaw and Yang, 2006). However, most information security awareness programs overlook human behavioural factors as a root cause of …

Il rapporto tra percezione e previsione in compiti di compatibilità spaziale
… intention (Michaels 1988; Hommel, 1993; Proctor, Van Zandt, Lu and Weeks, 1993; Ansorge, 2000). To investigate this we used a spatial compatibility task in 4 experiments replicating what had be done by Hommel (1993) and Micheals (1988), but changing a single aspect of the procedure: …

Dynamic analysis of dynamic cone penetration test for subgrade compaction assessment
… maximum dry unit weight obtained from Standard Proctor compaction test results. Nuclear gauges may be used to determine the in-place dry unit weight, however, they are potentially hazardous and require safety precautions. Other tests, such as the Dynamic Cone Penetration Test (DCPT), can be used …

Pavement thickness design using reclaimed hydrated Iowa class C fly ash as a base material
… lime and raw fly ash. Standard tests, including proctor density, gradation, and specific gravity were performed to compare the reclaimed fly ash to standard earth materials. Extensive strength testing was conducted using California Bearing Ratio and unconfined compressive strength tests. Results …
