Gebrekkige motivering as nie-tegniese oorsaak van pantograaf-rydraadverstrikkings

Coetzee, Martin Jacobus 14 August 2012 (has links)
M.Comm. / Spoornet ( South African Transport Services before 1991) realised since the early 1980's that pressure from its environment would have a serious effect on its economic survival. Since 1991 it has had to fight for its marketshare. Road transport companies started to beat Spoornet on all levels and robbed it of its client base. Spoornet was forced to reform its customer services approach. Pantograph-overheadwire entanglements is one of the obstacles in obtaining customer satisfaction due to the fact that one such incident can cause a train delay of up to three hours. Due the impact this has on the predictability of service, the Chief Engineer (Electrical) set as first objective an entanglement figure of 1 per million pantograph kilometres. A few informal investigations were made into possible technical reasons but none was made into the possible non-technical reasons. As hypothesis it was stated that the efforts of personnel in the organisation to solve the entanglement problem were being handicapped by the lack of motivation, which caused a atmosphere of conflict and frustration. This frustration and conflict has a negative influence on productivity and effectiveness which could be the cause of entanglements. Research done on this was conducted on a dual approach; Literature study as secondary information. Structured interview as primary information. The hypothesis was tested with this study and it was shown that inter-groupconflict, motivation, resource employment and the current approach all had aspects which needed to be addressed to solve the pantograph-overheadwire entanglement problem.

Transportation and Land Use Patterns: Monitoring Urban Change Using Aerial Photography, Portland, Oregon 1925-1945

Fyfield, Paul Hagen 01 January 2003 (has links)
American urban neighborhoods are a patchwork; the spatial arrangement of types is a reflection of the dominant transportation technology at the time of their development. The earliest suburban areas were made accessible by fixed route systems such as the electric streetcar, followed by the widespread adoption of the automobile; each transportation epoch resulted in characteristic patterns of land use. This study uses aerial photographic coverage of Portland, Oregon from the years 1925, 1936, and 1945, a time of decline for the once popular trolley lines and dramatic increase in automobile usage, to monitor change within the residential areas of Portland's east side over a twenty year period. Classic economic models of the time acknowledged transportation as a force shaping the city; modem ideas in urban planning such as Traditional Neighborhood Design and Transit Oriented Development look to pre-automobile urban form as a means to reduce automobile use and its negative implications. This study uses variables of housing density and street connectivity derived from the aerial photography; the measured values of these variables are then considered for their spatial and temporal distribution using statistical comparisons. The results are compared to ideas within the urban models and current thinking about urban morphology. While generally consistent with the expected patterns, deviations and differences between the two variables are considered for their implications. Models offer a simplified version of the growth of American cities, considering only a few of the many aspects of a dynamic environment. By isolating on these variables of density and connectivity, a greater understanding of their role in arriving at the modem residential urban environment may be reached, and this understanding can add to the discourse in current planning debates.
