TAFE-horticulture teachers’ conceptions of curriculum changes in Queensland, 1990-2003

The period from 1990-2003 was one of unprecedented curriculum change in the Queensland TAFE sector in general and Horticulture in particular. While curriculum theory had been clear for many years that teachers should be involved deeply in the curriculum process, data collected at the end of that period reveals that TAFE Horticulture teachers felt excluded and manipulated by the curriculum developers. With the benefit of distance, this thesis examines TAFE teachers’ conceptions of curriculum change in Horticulture and considers whether events since then have justified their reservations. The research paradigm of this study was informed by the qualitative research orientation of phenomenography based on extended interviews. The study revealed that teachers held eight qualitatively different conceptions of curriculum development. Some viewed the changes as representing a reduction in the quality of education, some as a retreat from education and training while others saw it as a reduction in the quality of teaching delivery. There were teachers who saw it as a way of saving money and others as causing instability and uncertainty, as exploitation of staff and a cause of extra (often unnecessary) work. Most saw the changes as imposed from above with the changes experienced as destructive to staff morale. Despite the generally negative conceptions of curriculum change, the study confirms the importance of teachers being regarded as central in the curriculum change process.

On Visual Detection of Highly-occluded Objects for Harvesting Automation in Horticulture

Developing accurate and reliable crop detection algorithms is an important step for harvesting automation in horticulture. This paper presents a novel approach to visual detection of highly-occluded fruits. We use a conditional random field (CRF) on multi-spectral image data (colour and Near-Infrared Reflectance, NIR) to model two classes: crop and background. To describe these two classes, we explore a range of visual-texture features including local binary pattern, histogram of oriented gradients, and learn auto-encoder features. The pro-posed methods are evaluated using hand-labelled images from a dataset captured on a commercial capsicum farm. Experimental results are presented, and performance is evaluated in terms of the Area Under the Curve (AUC) of the precision-recall curves.Our current results achieve a maximum performance of 0.81AUC when combining all of the texture features in conjunction with colour information.

Losses of nitrogen in surface runoff from a plantation horticulture farm in coastal Queensland, Australia.

Surface losses of nitrogen from horticulture farms in coastal Queensland, Australia, may have the potential to eutrophy sensitive coastal marine habitats nearby. A case-study of the potential extent of such losses was investigated in a coastal macadamia plantation. Nitrogen losses were quantified in 5 consecutive runoff events during the 13-month study. Irrigation did not contribute to surface flows. Runoff was generated by storms at combined intensities and durations that were 20–40 mm/h for >9 min. These intensities and durations were within expected short-term (1 year) and long-term (up to 20 years) frequencies of rainfall in the study area. Surface flow volumes were 5.3 ± 1.1% of the episodic rainfall generated by such storms. Therefore, the largest part of each rainfall event was attributed to infiltration and drainage in this farm soil (Kandosol). The estimated annual loss of total nitrogen in runoff was 0.26 kg N/ha.year, representing a minimal loading of nitrogen in surface runoff when compared to other studies. The weighted average concentrations of total sediment nitrogen (TSN) and total dissolved nitrogen (TDN) generated in the farm runoff were 2.81 ± 0.77% N and 1.11 ± 0.27 mg N/L, respectively. These concentrations were considerably greater than ambient levels in an adjoining catchment waterway. Concentrations of TSN and TDN in the waterway were 0.11 ± 0.02% N and 0.50 ± 0.09 mg N/L, respectively. The steep concentration gradient of TSN and TDN between the farm runoff and the waterway demonstrated the occurrence of nutrient loading from the farming landscapes to the waterway. The TDN levels in the stream exceeded the current specified threshold of 0.2–0.3 mg N/L for eutrophication of such a waterway. Therefore, while the estimate of annual loading of N from runoff losses was comparatively low, it was evident that the stream catchment and associated agricultural land uses were already characterised by significant nitrogen loadings that pose eutrophication risks. The reported levels of nitrogen and the proximity of such waterways (8 km) to the coastline may have also have implications for the nearshore (oligotrophic) marine environment during periods of turbulent flow.

Plant based monitoring for irrigation scheduling in vegetable horticulture: A case study in South Australian onions

Direct measurement of plant water status for irrigation scheduling may be more sensitive, and promote better horticultural crop quality, than indirect methods such as soil moisture monitoring. In our research project, we sought to identify instances where direct methods of plant-water status previously used in horticultural crops in Australia. We present the outcomes, suitability or obstacles for adoption by horticultural producers.

Intérêts professionnels d'élèves handicapés ou en difficulté d'adaptation ou d'apprentissage (EHDAA) inscrits à un programme d'intégration professionnelle axé sur l'horticulture

Cette recherche porte sur les intérêts professionnels d'élèves handicapés ou en difficulté d'adaptation ou d'apprentissage (EHDAA) inscrits à un programme d'intégration professionnelle axé sur l'horticulture. Elle s'attarde aussi à leur environnement scolaire et professionnel. Les résultats obtenus lors de la passation en .prétest de l'Inventaire visuel d'intérêts professionnels (IVIP) montrent que les intérêts professionnels de la majorité des élèves sont congruents avec leur formation scolaire. Quant aux résultats observés au post-test, ils révèlent que cette congruence est moins élevée dans les profils d'intérêts de ces élèves et que la majorité d'entre eux ne sont pas en emploi à la fin de leur programme d'intégration professionnelle. Cette situation pourrait entre autres s'expliquer par les limitations et les besoins spécifiques de ces élèves qui rendent difficile l'accompagnement soutenu des employeurs ainsi que par d'autres considérations telles que l'offr d'emploi et la disponibilité de programmes d'intégration professionnelle variés.
