Education for an Australian Choral Tradition: evaluating the philosophies of Stephen Leek

Stephens, Annette, res.cand@acu.edu.au January 2005 (has links)
The thesis aimed to assess the philosophies of Stephen Leek, in regard to the education for an Australian choral tradition. In order to address Stephen Leek's philosophies, a study of Australia's existing choral tradition and its history was conducted. This was followed by a general overview of music education in Australia post 1960. In light of these findings, Leek's educational philosophies were discussed, with specific influences, including biographical information. Leek's educational work Voiceworks was found to encapsulate his ideas. The program is creative-based, and aims to facilitate the discovery of new artistic concepts, and foster acceptance and interest in contemporary Australian choral music. Using the voice as the sole instrument, students can perform the pieces from Voiceworks, or use the ideas for further creativity in their own compositions. The program is based on experimentation, discovery, structuring, formulating, rehearsal, performance and discussion. Leek advocates that these stages are the quickest and most effective way of facilitating the learning of contemporary music techniques. In the evaluation of Leek's philosophies, case studies using a lesson from Voiceworks, were conducted with two Year 7 music classes in two different government coeducational schools. The findings revealed that Voiceworks can be a successful resource in the education for an Australian choral tradition. However, it was also found that excitement, enthusiasm and enjoyment are the key to its success, and hence excellent teaching is required in its presentation.

Auginimo būdų įtaka skirtingo ankstyvumo porų derliui ir kokybei / YIELD AND QUALITY OF LEEKS AS AFFECTED BY METHOD OF GROWING

Sakalauskienė, Sandra 28 April 2006 (has links)
The research was carried out in 2005 at the Lithuanian University of Agriculture, Department of Horticulture. The aim of research was to investigate the yield and quality of different leeks cultivars as influenced by different grown methods. Leeks were growing in these ways: I way – growing in smooth surface; 2 way – growing into 15 cm deep furrows; 3 way - growing on the 15 cm furrows; 4 way – growing in the holes of 20 cm depth. The biggest harvest has been received from the early leek varieties, total harvest - 36,63 t ha-1, standard harvest – 31,12 t ha-1 and late leek varieties total harvest - 26,85 t ha-1, standard harvest – 24,05 t ha-1) grown in smooth surface. The early leeks grown in the holes of 20 cm depth has been received the biggest mass per plant (average 325,0 g) and mass per plant of the late leeks has been received from the leeks grown on the 15 cm furrows (average 274,7 g). The early leeks of the best biochemical composition have been grown in the holes of 20 cm depth and the late leeks have been grown on the 15 cm furrows.

Mapping Wild Leek with UAV and Satellite Remote Sensing

Miglhorance, Edmar 05 March 2019 (has links)
Wild leek (Allium tricoccum) is a spring ephemeral of northeastern North America. In the Canadian province of Quebec, it is listed as threatened due to human harvesting, and in Gatineau Park its presence is used as an indicator of human impact. Wild leek grows in patches on the forest floor, and before the tree canopy develops its green leaves are clearly visible through the bare branches of deciduous forests, allowing it to be observed with optical remote sensing. This study developed and tested a new method for monitoring wild leek across large geographic areas by integrating field observations, UAV video, and satellite imagery. Three-cm resolution orthomosaics were generated for five <0.1 km2 sites from the UAV video using Structure-from-Motion, segmented, and classified into wild leek (WL) or other (OT) surface types using a simple greenness threshold. The resulting maps, validated using the field observations, had a high overall accuracy (F1-scores between 0.64 to 0.94). These maps were then used to calibrate a linear model predicting the per-pixel percentage cover of wild leek (%WL) from NDVI in the satellite imagery. The linear model calibrated for a Sentinel-2 image from 2018, covering all of Gatineau Park (~361 km2), allowed %WL to be predicted with an RMSE of 10.32. A similar model calibrated for a WorldView-2 image from 2018 was noisy (RMSE = 37.64), though much improved by resampling this image to match the spatial resolution of Sentinel-2, due to MAUP scale effect (RMSE = 13.06). Testing the potential for satellite-based monitoring of wild leek, the %WL prediction errors were similar when a new linear model was developed using the Sentinel-2 image from 2017 (RMSE = 12.84) and when the model calibrated with the 2018 Sentinel-2 image was applied to the 2017 satellite data (RMSE = 16.97). The linear models developed for the Sentinel-2 and WorldView-2 images from 2018 were used to map wild leek cover for Gatineau Park. Both images allowed production of similar wild leek maps that, based on field experience and visual inspection of the imagery, provide good descriptions of the actual distribution of wild leek at Gatineau Park.

The relationships between plant responses to arbuscular mycorrhizal fungi and phosphorus dynamics in the hyphae.

Title page, table of contents and abstract only. The complete thesis in print form is available from the University of Adelaide Library. / Two experiments were conducted to find diversity in plant responses to arbuscular mycorrhizal (AM) fungi: positively and negatively/non-responsive combinations. Medic (Medicago truncatula L.) tomato (Solanum esculentum L.), leek (Allium porrum L.) and cucumber (Cucumis sativus L.) were inoculated with Glomus intraradices, Gigaspora margarita and Scutellospora calospora. It was found that soil differences critically affect plant responses to AM fungi. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1283734 / Thesis (Ph.D.) -- University of Adelaide, School of Earth and Environmental Sciences, 2007
