Managing change without sacrificing quality: music teaching and learning at South African tertiary institutions

After the jubilation of the first democratic election in 1994, South African educational settings were faced with the challenge to rethink curriculum, content and delivery as part of its nation building process. Education continues to be a major player in stimulating wider change in society and is one arena where change may be readily facilitated. Changing the style and practice of teacher education programs remains a key feature in the transformation process. Twelve years on, curriculum, has undergone reform in terms of Outcomes Based Education (OBE)? Revised National Curriculum Statement (RNCS) of 2002, accordingly, universities continue to prepare teachers for multicultural classrooms. Universities are now challenged to manage increased student intake (quantity) for teacher education programs without having to sacrifice quality for teacher education. This article focuses only on The University of Pretoria, a city university previously known as a traditional Afrikaans university situated in the greater Johannesburg area in South Africa. Through interview data with two music educators at this university, I present some of the current trends and challenges that tertiary music educators face in preparing music teachers in South Africa. This article also outlines a paradigm shift in the curriculum and argues for a holistic music education, one that endorses most of the major cultures and musics in South Africa. The question I pose is how then do we effectively manage change at tertiary level without sacrificing quality when preparing future music teachers to meet the needs and challenges of the curriculum and society.

Multiple criteria sustainability modelling

This paper describes the research supported by a recent AIQS research grant to develop a computer-based tool for sustainability modeling using multiple criteria. The model enables a sustainability index with an accept/reject threshold of one that has the potential to completely replace traditional net present value methods. Minimum performance benchmarks are prescribed and must be observed - often by trading off performance across the full criteria set. Sustainability is shown to be capable of objective (numeric) analysis for new projects, existing facilities, or indeed any product or asset. A combination of investor-centred and community-centred motivations can also be explored in the model. Known as SINDEX, the tool has industry-wide application, both locally and abroad, and represents a paradigm shift in project evaluation techniques. Furthermore, its multi-discipline considerations underscore the importance of a team approach to sustainability modeling and the need for people to work more closely together when dealing with complex problems

Defuturing an architecture of destruction: a reconciliation of Van Berkel and Bos to the new design philosophy of Tony Fry

For some time now Tony Fry has promoted the idea of 'The Sustainment', an idea that asserts a paradigm shift in attitudes to consumption. 'The Sustainment' recognises that increasingly human futures are products of self-determination and not chance. Fry’s hypothesis can be understood through his concept of Defuturing, a philosophy that questions the role of design and the responsibility of designers to facilitating the ability to sustain (Fry 1999).
Central to Fry’s philosophy is an awareness that it is in the best interests of designers and their clients, as inhabitants of cultures increasingly driven by technology, to be aware of the relationships between the products and theories of design and the processes and implications of technological change. This is an awareness that is central to the concepts, work, and methodologies of the ‘UN Studio’ of Van Berkel and Bos described and elaborated upon in Move – Imagination, Techniques, and Effects (Van Berkel & Bos 1999). Here, Ben Van Berkel defines the parameters and methodologies employed by UN Studio in an environment of technological and socio-economic change. The Dutch practice could be said to exemplify something of a zeitgeist in current architectural design that sees architects, as Van Berkel and Bos view them, as “fashion designers of the future, dressing events to come and holding up a mirror to the world (Van Berkel & Bos 1999, back cover).” It is a zeitgeist that Fry might see as aligned to the resilient hype of ‘new creativity’, ‘globalisation’ the ‘romance with technology’, and the vacuous-ness of the world of fashion. (Fry The Voice of Sustainment: on Design Intelligence 2005).
A source of breaking down such design propaganda is identified by Fry in the notion of ‘scenarios,’ which “provide a mechanism for politico-practice assemblage in which dialogues and narratives of change can be rehearsed in ways that enable participants to re-educate themselves via critical confrontations” (Fry The Voice of Sustainment: on Design Intelligence 2005). From such a perspective this paper aims to practically illustrate and ground the Defuturing of Fry by establishing a dialogue between his writings and the theories that have generated the architectural designs of Van Berkel and Bos and there UN Studio. This will be a ‘scenario’ that examines therefore an appropriation and transformation of the applied intellectual practice of Van Berkel and Bos. Through this confrontation we shall explore the question of why sustainability appears to be so low in the agenda of many pre-eminent contemporary architects, and how we might refocus therefore practice and theory on the ability to sustain.

Multiple criteria sustainability modelling: case study on school buildings

This paper describes development of a computer-based tool for sustainability modelling using multiple criteria, and preliminary conclusions from doctoral research being undertaken into the relationship between key sustainability indicators. The model used in both cases produces a sustainability index with an accept/reject threshold of one that has the potential to completely replace traditional net present value methods. Minimum performance benchmarks are prescribed and must be observed - often by trading off performance across the full criteria set. Sustainability is shown to be capable of objective (numeric)· analysis for new projects, existing facilities, or indeed any product or asset. A combination of investor-centred and community-centred motivations can also be explored in the model. Known as SINDEX, the tool has industry-wide application, both locally and abroad, and represents a paradigm shift in project evaluation techniques. Furthermore, its multi-discipline considerations underscore the importance of a team approach to sustainability modelling and the need for people to work more closely together when dealing with complex problems. The results of twenty case studies of actual high schools constructed and operated in New South Wales (Australia) are also presented and the relationships between the key sustainability indicators are explored and interpreted.

The Asia Pacific literature review on internal auditing

Purpose – By conducting the 2006 global Common Body of Knowledge (CBOK) study, The Institute of Internal Auditors (IIA) attempts to better understand the expanding scope of internal auditing practice throughout the world. The purpose of this review of recent internal auditing literature in Asia Pacific is to document how the internal audit function is changing in response to the shifts in global business practices.
Design/methodology/approach – The literature in Asia Pacific is reviewed with a focus on developments that have implications for the expanded scope of internal auditing and the changing skill sets of internal auditors. This focus has implications for CBOK 2006.
Findings – The literature indicates a paradigm shift in the activities performed by internal auditors. The increasing complexity of business transactions, a more dynamic regulatory environment in Asia Pacific, and significant advances in information technology have resulted in opportunities and challenges for internal auditors. Although in 2004, The IIA responded to the changing organizational environment by updating the professional practices framework, more work needs to be done to prepare internal auditors for the expanded set of skills and knowledge required to perform audits of the future.
Originality/value – By presenting an overview of past literature in Asia Pacific and discussing the shifting demands on internal audit services, the researchers hope to motivate further research in the field.

Climate change and social inclusion: opportunities for justice and empowerment

...the greatest untapped resource at our disposal lies in the disadvantaged Australians living in our most excluded communities. (Nicholson 2007 p. 4)

The commons are where justice and sustainability converge, where ecology and equity meet. (Shiva 2005 p. 50)

Since 1990, the Intergovernmental Panel on Climate Change (IPCC) has recognised human induced climate change to be primarily a result of burning fossil fuels and land clearing (Lee 2007). Changes to the world's climate patterns have been occurring for decades, but only in recent times has climate change arrived in our collective conscious. An onslaught of extreme weather events, destruction and failure of crops, increasing levels of water restrictions, government announcement of desalination plants. proposed increase in prices for utilities such as power and water - have ushered climate change into the Australian lexicon.

The challenges for all of us are many and varied and perhaps even unimaginable. as many propose a global reduction in annual C02 emissions of between 60-80% (compared to 1990 levels) by 2050.

We are not talking just about the re-construction of our world, but about its re-invention. Ryan (2007)

How will climate change affect us? Who is most vulnerable? What will be the features of policies and strategies to combat climate change that ensure an equitable and just response across our entire society? Are our present social-cultural justice paradigms of social exclusion and inclusion adequate in addressing the impending health consequences that are likely to result from climate change, and in supporting an equitable. harmonious and fruitful life for all population groups in the future?

This paper, written in the spirit of solution-oriented research. focusing on the causes of positive health rather than the causes of disease and other problems (Robinson & Sirard 2005). explores the possibility of a paradigm shift which imagines the social inclusion of specific population groups, not as an appended extra, but integral to the design of an equitable, sustainable low carbon society of the future.

Crisis in Clio's family : a study of the discipline of Australian economic history 1918-1965

This thesis presents an intellectual history of the historiography of Australian Economic History between 1918 and 1965. More specifically, it is a contribution to a relatively novel area of research into 'disciplinary history’. It takes as its basic analytical material the four books widely used for significant lengths of time for undergraduate teaching during the period of the study. The thesis consists of five main chapters, plus an appendix which surveys the institutional development of Australian Economic History and provides the empirical basis for the selection of the works named above. After a brief introduction and overview, the next four chapters consist of a detailed study of one of these works, the historical context in which each was written, and an intellectual biography. The fifth chapter is largely theoretical and conceptual. It analyses the epistemological bases of History and Economics and explores the implications of different models of knowledge for the relationship between Economic History and its two antecedent disciplines, History and Economics. Current perceptions of the state of the discipline in Australia and overseas are also examined. There are three main propositions advanced and their implications explored in the fifth chapter. First, that changes which occurred in Australian Economic History during the period 1918-1965 shifted the discipline from the broad area of History to the broad area of Economics. Second, that the inherent tension and fundamental differences between the two disciplinary areas of History and Economics have profound and complex implications for Australian Economic History at a number of levels and in a number of areas. The third proposition posits that the paradigm shift of the 1950s/1960s in Australian Economic History, and the paradigm shift of the 1960s/1970s in Economic History respectively have resulted in crisis. The final part of the chapter summarises the contents of the preceding chapters, and draws some conclusions based on those detailed studies.

Subjective wellbeing

The thesis proposes that depression can be understood as a consequence of the failure to maintain subjective wellbeing. This represents a paradigm shift from the view of depression as being caused by negative affect. It suggests a new diagnostic approach that uses measures of wellbeing as indicators of depression.

The nature of change

This thesis presents a conceptual framework that describes the diversity of real things found in nature: individual, categorical and universal things. The multi-faceted approach to causality represents a paradigm shift; enabling, for the first time, the integration of random, ordered and stochastic events in a single schematic.

Adoption of VIDEOoverIP by deaf people in the workplace

This study explored deaf employees' adoption of videocommunication-via-the Internet, allowing sign language use between deaf people, and between deaf and hearing people via Video Relay Interpreting service. Major findings included a paradigm shift from text to video communication; and, a divergence from typical adoption theory, with government intervention required to prime the adoption of videocommunication by deaf people in Australia.

Toward ease of discovery, selection and use of clusters within a cloud

While the emergence of clouds had lead to a significant paradigm shift in business and research, cloud computing is still in its infancy. Specifically, there is no effective publication and discovery service nor are cloud services easy to use. This paper presents a new technology for offering ease of discovery, selection and use of clusters hosted within clouds. By improving these services, cloud clusters become easily accessible to all clients, software services to noncomputing human user.

Defending against large-scale and coordinated attacks in the ubiquitous environments

Ubiquitous computing is an exciting paradigm shift where technology becomes virtually invisible in our lives. In the increasingly interconnected world, threats to our daily lives can come from unexpected sources and universal directions. Criminals and terrorists have recognized the value of leveraging the ubiquitous computing environments to facilitate the commission of crimes. The cyber criminals typically launch different forms of large-scale and coordinated attacks, causing huge financial loss and potential life hazard. In this talk, we report two innovative approaches to defend against large-scale and coordinated attacks in the ubiquitous environments: 1) Inferring the cyber crime's intent through network traffic classification to enable the early warning of potential attacks, and 2) Profiling the large-scale and coordinated cyber attacks through both microscopic and macroscopic modeling to provide better control of such attacks. These approaches are effective in finding weak symptoms caused by the attacks thus can successfully defend against the large-scale and coordinated attacks at their early stages.

Cultural diversity, cultural heritage and human rights : towards heritage management as human rights-based cultural practice

The present article investigates the linkages between conserving cultural heritage, maintaining cultural diversity and enforcing human rights. While there seems to be a growing awareness of these linkages in international heritage and human rights circles, they remain poorly understood by many heritage practitioners who see their conservation work merely as a technical matter. The article argues that it is essential for practitioners engaged in heritage conservation projects to understand the broader economic, political and social context of their work. However, heritage scholars and teachers, too, need to recognise that there can be many motives behind official heritage interventions, that such action is sometimes taken primarily to achieve political goals, and that it can undermine rather than strengthen community identity, cultural diversity and human rights. Such a reorientation is an extension of the paradigm shift in which heritage is understood as cultural practice. In this more critical heritage studies discipline human rights are brought to the foreground as the most significant part of the international heritage of humanity.

Resolving controversies in hip fracture care : the need for large collaborative trials in hip fractures

Summary: Hip fractures are a significant cause of morbidity and mortality worldwide and the burden of disability associated with hip fractures globally vindicates the need for high-quality research to advance the care of patients with hip fractures. Historically, large, multi-centre randomized controlled trials have been rare in the orthopaedic trauma literature. Similar to other medical specialties, orthopaedic research is currently undergoing a paradigm shift from single centre initiatives to larger collaborative groups. This is evident with the establishment of several collaborative groups in Canada, in the United States, and in Europe, which has proven that multi-centre trials can be extremely successful in orthopaedic trauma research.

Despite ever increasing literature on the topic of his fractures, the optimal treatment of hip ftractures remains unknown and controversial. To resolve this controversy large multi-national collaborative randomized controlled trials are required. In 2005, the International Hip Fracture Research Collaborative was officially established following funding from the Canadian Institute of Health Research International Oppurtunity Program with the mandate of resolving controversies in hip fracture management. This manuscript will describe the need, the information, the organization, and the accomplishments to date of the International Hip Fracture Research Collaborative.

Climate change impacts : challenges for aquaculture

In spite of all the debates and controversies, a global consensus has been reached that climate change is a reality and that it will impact, in diverse manifestations that may include increased global temperature, sea level rise, more frequent occurrence of extreme weather events, change in weather patterns, etc., on food production systems, global biodiversity and overall human well being. Aquaculture is no exception. The sector is characterized by the fact that the organisms cultured, the most diverse of all farming systems and in the number of taxa farmed, are all poikilotherms. It occurs in fresh, brackish and marine waters, and in all climatic regimes from temperate to tropical. Consequently, there are bound to be many direct impacts on aquatic farming systems brought about by climate change. The situation is further exacerbated by the fact that certain aquaculture systems are dependent, to varying degrees, on products such as fishmeal and fish oil, which are derived from wild-caught resources that are subjected to reduction processes. All of the above factors will impact on aquaculture in the decades to come and accordingly, the aquatic farming systems will begin to encounter new challenges to maintain sustainability and continue to contribute to the human food basket. The challenges will vary significantly between climatic regimes. In the tropics, the main challenges will be to those farming activities that occur in deltaic regions, which also happen to be hubs of aquaculture activity, such as in the Mekong and Red River deltas in Viet Nam and the Ganges-Brahamaputra Delta in Bangladesh. Aquaculture in tropical deltaic areas will be mostly impacted by sea level rise, and hence increased saline water intrusion and reduced water flows, among others. Elsewhere in the tropics, inland cage culture and other aquaculture activities could be impacted by extreme weather conditions, increased upwelling of deoxygenated waters in reservoirs, etc., requiring greater vigilance and monitoring, and even perhaps readiness to move operations to more conducive areas in a waterbody. Indirect impacts of climate change on tropical aquaculture could be manifold but are perhaps largely unknown. The reproductive cycles of a great majority of tropical species are dependent on monsoonal rain patterns, which are predicted to change. Consequently, irrespective of whether cultured species are artificially propagated or not, changes in reproductive cycles will impact on seed production and thereby the whole grow-out cycle and modus operandi of farm activities. Equally, such impacts will be felt on the culture of those species that are based on natural spat collection, such as that of many cultured molluscs. In the temperate region, global warming could raise temperatures to the upper tolerance limits of some cultured species, thereby making such culture systems vulnerable to high temperatures. New or hitherto non-pathogenic organisms may become virulent with increases in water temperature, confronting the sector with new, hitherto unmanifested and/or little known diseases. One of the most important indirect effects of climate change will be driven by impacts on production of those fish species that are used for reduction, and which in turn form the basis for aquaculture feeds, particularly for carnivorous species. These indirect effects are likely to have a major impact on some key aquaculture practices in all climatic regimes. Limitations of supplies of fishmeal and fish oil and resulting exorbitant price hikes of these commodities will lead to more innovative and pragmatic solutions on ingredient substitution for aquatic feeds, which perhaps will be a positive result arising from a dire need to sustain a major sector. Aquaculture has to be proactive and start addressing the need for adaptive and mitigative measures. Such measures will entail both technological and socio-economic approaches. The latter will be more applicable to small-scale farmers, who happen to be the great bulk of producers in developing countries, which in turn constitute the “backbone’ of global aquaculture. The sociological approaches will entail the challenge of addressing the potential climate change impacts on small farming communities in the most vulnerable areas, such as in deltaic regions, weighing the most feasible adaptive options and bringing about the policy changes required to implement these adaptive measures economically and effectively. Global food habits have changed over the years. We are currently in an era where food safety and quality, backed up by ecolabelling, are paramount; it was not so 20 years ago. In the foreseeable future, we will move into an era where consumer consciousness will demand that farmed foods of every form will have to include in their labeled products the green house gas (GHG) emissions per unit of produce. Clearly, aquaculture offers an opportunity to meet these aspirations. Considering that about 70 percent of all finfish and almost 100 percent of all molluscs and seaweeds are minimally GHG emitting, it is possible to drive aquaculture as the most GHG-friendly food source. The sector could conform to such demands and continue to meet the need for an increasing global food fish supply. However, to achieve this, a paradigm shift in our seafood consumption preferences will be needed.
