SS Xantho: towards a new perspective. An integrated approach to the maritime archaeology and conservation of an iron steamship wreck

The assessment and excavation of the wreck of the iron-hulled SS Xantho (1848-72) has shown that otherwise unobtainable information about both materials and people can be found in the archaeological study of iron and steamship wrecks. One important development has been the initiation of full pre-disturbance studies of a shipwreck's biological and electrochemical properties, giving insights into the condition of the site and its materials of value to both the archaeologist and conservator. Conducted by diving conservation specialists at the request of the archaeologist, this was the first such comprehensive study to be performed on any underwater site. It is now recognised as an essential element in any modem maritime archaeological project. Site inspection revealed that Xantho was powered by a former Royal Navy gunboat engine, of a type that was evidently the first high pressure, high revolution and mass produced marine engine made. Despite these advances, they were suitable only for use in a naval context. The ship itself was a former paddle-steamer built in the formative years of iron shipbuilding. After 23 years of service it was sold to a scrap metal merchant who joined the hull to the second-hand screw-engine and offered the revamped hybrid for sale. That the ship appeared on the sparsely populated and poorly serviced Western Australian coast, far from coal supplies and marine engine repair facilities, posed an immediate question; what sort of person would use it in this manner? Thus the Xantho program came to focus on Charles Edward Broadhurst and how he came to make the apparently strange decision to purchase such an odd and apparently unsuitable vessel. Archival study and an excavation of the stem section of the wreck were conducted for these purposes. The study of Broadhurst was completed in 1990, the subject of the author's Masters thesis, resurrecting and analysing the entire business career and life of one of Western Australia's forgotten, but most active and controversial colonial entrepreneurs. This thesis centres on the excavation of Broadhurst's ship and describes the recovery of the ship's engine from a highly-oxygenated salt-water environment. The recovery of the engine was followed by conservation treatment and an archaeologically-based 'excavation' of the heavily concreted engine in the laboratory. Begun in 1985 the deconcretion was completed by mid 1995 with the opening up of the last of the internal spaces and the freeing of all working parts in preparation for the engine's reassembly and exhibition. The successes of the two 'excavations' have confirmed both the place of the conservator on the sea-bed and the archaeologist's place in the conservation process. the disassembly of the engine, where nearly two tonnes of concretions were removed, evidence was found of technical significance and of the way Charles Broadhurst, the vessel's owner operated the ship. I also describe commonalities evident in the formation of iron and steamship wreck sites. This enables anomalies noted at the Xantho site to be assessed and quantified against a broader sample, leading to a focus on the behaviour of steamship owners in a frontier environment and the postulation of a number of testable propositions about the material residues of such behaviours

A collaborative framework for enhancing sustainable learning for learners with disruptive behaviour in a rural school context.

Doctoral Degree. University of KwaZulu-Natal, Durban.This study investigated how a collaborative framework could be utilised to enhance sustainable learning among learners with disruptive behaviour in a rural school context in Zimbabwe. The literature confirms that a collaborative framework has the potential to emancipate and empower teachers, parents, other stakeholders interested in education and all learners, including those with disruptive behaviour. Working within the critical emancipatory research paradigm, the study involved participants from a rural school context. An eclectic approach that combined the theory of Ubuntu and the concept of critical consciousness was employed to understand disruptive behaviour as a socially constructed challenge in a natural setting. While Ubuntu highlights collaboration, interconnectedness and interdependency among people, critical consciousness aims to promote critical thinking, emancipation and empowerment, and address inequality, oppression, domination, suppression and alienation. Participatory action research design, provided a platform for the participants to critically engage in meaning-making discourses about the lives and circumstances of learners with disruptive behaviour in a rural school context. Purposive selection was utilised to select participants and the data was generated by means of focus group discussions, document analysis and reflective journals. The data were analysed following three levels of using critical discourse analysis. The study’s findings revealed that there was limited collaboration to deal with disruptive learner behaviour in this rural school context. The participants noted that such behaviour has mainly negative consequences for learners, teachers, parents and the broader community and that it needs to be addressed in order to enhance sustainable learning. The challenges that hinder collaborative practices, strategies to mitigate them and preventative measures that could be adopted to prevent disruptive behaviour were identified. Finally, the participants agreed that a collaborative framework should be utilised to address this issue and that monitoring and evaluation should be conducted at all levels of the framework. Based on these findings the study proposes a collaborative framework to enhance sustainable learning for learners with disruptive behaviour in a rural school context

Hands-on science: science education with and for society

The decisive importance of Science on the development of modern societies gives Science Education a role of special impact. Society sets the requirements rules and procedures of Education defining what concepts and competencies citizens must learn and how this learning should take place. Educational policies set by governments, elected and or imposed, not always reflects the will and ruling of Society. The School as pivotal element of our modern educational system must look behind and beyond imposed rules and regulations and persistently seek a permanent and open relation with Society, in all its dimensions, assuming and defending its crucial role on the development of Society and humankind. Aiming to contribute to an effective implementation of a sound widespread scientific literacy and effective Science Education in our Schools and Society at large, the Hands-on Science Network promotes a number of meetings and conferences open to the widest range of contributions on different pedagogic approaches with the common goal of promoting an effective learning of Science. This book gathers a number of interesting works presented at the 11th International Conference on Hands-on Science held in Aveiro, Portugal, July 21 to 25, 2014. The different chapters covers a wide range of topics including different strategies on connecting school’ science education with society and on synergetic relations between Society and Science Education, reports on good practices on formal as well as non-formal or informal science education, ICT tools, IBSE, active learning and hands-on pedagogy. We believe that the materials herein are a rather useful tool to assist teachers and educators as well as all interested in Science Education and its impact on the development of our Societies

John Clark : transformation and the void : with a catalogue raisonné

29 cm.The intent of the thesis is twofold: interpretive and documentary. Volume 1 focuses on the work John Clark considered to be his mature oeuvre. The general structure is chronological, with the first three chapters devoted to formative influences, and a further chapter to what Clark had to say about meaning in his own work and that of others. The remaining four chapters offer an interpretation of the mature paintings in terms of two concepts: trasformation and the void. Annotated bibliographies and exhibition lists are included. The catalogue raisonne, volume 2, is an ongoing project to provide as complete a chronological record of Clark's known works as is possible: paintings, drawings (including working studies), prints, and reporduction histories are included. Appendices record missing and destroyed works, a bibliography of Clark's personal library, transcripts of three interviews and a lecture
