The relationship between leadership practices and organisational culture: An education management perspective
The relationship between leadership practice of the principal and school culture was investigated and recommendations on the skills principals need to establish a school culture conducive to teaching and learning are provided. Two standardised questionnaires were used to measure the existing leadership practices and organisational culture in 30 schools. Correlations between leadership practices and school cultures were determined by means of linear regressions and portrayed by scatter plots. It was found that each of the leadership practices tested was positively related to either of the two main elements of organisational culture: sociability or solidarity. The findings provided a sound basis for the appointment of principals able to cultivate a positive school culture.Keywords: correlation; culture; education; leadership; management; organisation; relationshipSouth African Journal of Education Vol. 26 (4) 2006: pp. 609-62

Interdisciplinary research on the application of ERTS-1 data to the regional land use planning process
The author has identified the following significant results. Although the degree to which ERTS-1 imagery can satisfy regional land use planning data needs is not yet known, it appears to offer means by which the data acquisition process can be immeasurably improved. The initial experiences of an interdisciplinary group attempting to formulate ways of analyzing the effectiveness of ERTS-1 imagery as a base for environmental monitoring and the resolution of regional land allocation problems are documented. Application of imagery to the regional planning process consists of utilizing representative geographical regions within the state of Wisconsin. Because of the need to describe and depict regional resource complexity in an interrelatable state, certain resources within the geographical regions have been inventoried and stored in a two-dimensional computer-based map form. Computer oriented processes were developed to provide for the economical storage, analysis, and spatial display of natural and cultural data for regional land use planning purposes. The authors are optimistic that the imagery will provide revelant data for land use decision making at regional levels
The use of ERTS-1 data for the inventory of critical land resources for regional land use planning
Computer-generated spatial and statistical comparisons of critical land resource data derived from conventional sources, RB-57 photographs, and ERTS images, for an eastern Wisconsin test site, suggest that certain critical land resource data can be mapped from ERTS images on a statewide basis. This paper presents one of the biotic resources, wetlands, as an example of the use of ERTS imagery to inventory land resources
