A Euro-American-Australian study of the mechanical engineering profession as a foundation for the study of mechanical engineering attributes

The increasing attribute focus in the formation (engineering education, training, work-based learning and experience) of engineers now being adopted by engineering education accrediting bodies is based on meeting the perceived needs of professional practice. Related to this is an increasing expectation of new graduates being work-ready rather than relying on work-based learning and experience to develop many of the essential professional practice attributes.

The scope of the mechanical engineering profession is broad and practitioners contributing to debate on attribute requirements have their own individual views of the nature of the profession, largely influenced by their own professional formation. As a foundation for detailed study on attribute requirements for effective Australian professional mechanical engineers, in this paper we provide a concise study of the development of the established scope of practice and knowledge base of the profession over the last two centuries. Formation practices in Europe and the United States played significant roles in the 19th century.

We conclude with a discussion on the impact of the considerable changes currently affecting mechanical engineering practice in the UK, US and Australia, including organisational, technical and societal expectations, industry profile, and educational factors.

Exchange rate exposure, foreign currency derivatives and the introduction of the euro: French evidence

We investigate the impact of the introduction of the Euro on exchange rate exposures for French corporations and examine the corporate use of foreign currency derivatives to hedge exchange rate exposure post-Euro. Our findings indicate that the introduction of the Euro is associated with both a reduction in the number of firms that have significant exchange rate exposure and the absolute size of exposure. Consistent with these reduced exposures, French firms use foreign currency derivatives less intensively. Furthermore, the use of foreign currency derivatives is found to be associated with lower exchange rate exposure but there is insufficient evidence that these instruments are more effective in the post-Euro environment.

The credit spread dynamics of Latin American euro issues in international bond markets

This paper investigates two important relationships using the sovereign issues made by major Latin American economies in the international bond market: the determinants of credit spread changes using variables derived from structural and macroeconomic theory and the impact of a default episode on the underlying equilibrium dynamics. We find four significant determinants of credit spread changes: an asset and interest rate factor—consistent with structural models of credit spread pricing; the exchange rate—consistent with macroeconomic determinants and the slope of the yield curve—consistent with a business cycle effect. Also, an intra-regional analysis of sovereign yields reveals a shift in the long-run equilibrium dynamics around the Argentine default on the 23 December 2001.

Characterising vehicle emissions from the burning of biodiesel made from vegetable oil

Biodiesel manufactured from canola oil was blended with diesel and used as fuel in two diesel vehicles. This study aimed to test the emissions of diesel engines using blends of 100%, 80%, 60%, 40% , 20% biodiesel and 100% petroleum diesel, and characterise the particulate matter and gaseous emissions, with particular attention to levels of polycyclic aromatic hydrocarbons (PAHs) which are harmful to humans. A real time dust monitor was also used to monitor the continuous dust emissions during the entire testing cycle. The ECE(Euro 2) drive cycle was used for all emission tests. It was found that the particle concentration was up to 33% less when the engine burnt 100% biodiesel, compared to 100% diesel. Particle emission reduced with increased percentages of biodiesel in the fuel blends. Reductions of NOx, HC and CO were limited to about 10% when biodiesel was burned. Levels of CO2 emissions from the use of biodiesel and diesel were similar. Eighteen EPA priority PAHs were targeted, with only 6 species detected in the gaseous phase from the samples . 9 PAHs were detected in particulate phases at much lower levels than gaseous PAHs. Some marked reductions were observed for less toxic gaseous PAHs such as naphthalene when burning 100% biodiesel, but the particulate PAH emissions, which have more implications to adverse health effects, were virtually unchanged and did not show a statistically significant reduction. These findings are useful to gain an understanding of the emissions and environmental impacts of biodiesel.

Processing and mechanical properties of porous Ti-Mo alloy for biomedical applications

Titanium and some of its alloys are well accepted as load-bearing implant materials due to their excellent mechanical properties, superior corrosion resistance, and outstanding biocompatibility. However, solid implant materials may suffer from the problems of adverse tissue reaction, biomechanical mismatch and lack of new bone tissue ingrowth ability. In the present study, porous titanium-molybdenum (Ti-Mo) alloy was fabricated by the space-holding sintering method. The pore size, pore shape and porosity can be controlled through choosing appropriate space-holding particle materials. Electron scanning microscopy (SEM) was used for the characterisation of the porous Ti-Mo alloy. The mechanical properties of the porous Ti-Mo alloy samples were investigated by compressive tests. Results indicated that the porous Ti-Mo alloy provides promising potential for new implant materials with new bone tissue ingrowth ability and mechanical properties mimicking those of natural bone.

Reconstruction of in vivo time-evolving neuroendocrine dose - response properties unveils admixed deterministic and stochastic elements

Homeostasis in the intact organism is achieved implicitly by repeated incremental feedback (inhibitory) and feedforward (stimulatory) adjustments enforced via intermittent signal exchange. In separated systems, neurohormone signals act deterministically on target cells via quantifiable effector-response functions. On the other hand, in vivo interglandular signaling dynamics have not been estimable to date. Indeed, experimentally isolating components of an interactive network definitionally disrupts time-sensitive linkages. We implement and validate analytical reconstruction of endogenous effector-response properties via a composite model comprising (i) a deterministic basic feedback and feedforward ensemble structure; (ii) judicious statistical allowance for possible stochastic variability in individual biologically interpretable dose–response properties; and (iii) the sole data requirement of serially observed concentrations of a paired signal (input) and response (output). Application of this analytical strategy to a prototypical neuroendocrine axis in the conscious uninjected horse, sheep, and human (i) illustrates probabilistic estimation of endogenous effector dose–response properties; and (ii) unmasks statistically vivid (2- to 5-fold) random fluctuations in inferred target-gland responsivity within any given pulse train. In conclusion, balanced mathematical formalism allows one to (i) reconstruct deterministic properties of interglandular signaling in the intact mammal and (ii) quantify apparent signal-response variability over short time scales in vivo. The present proof-of-principle experiments introduce a previously undescribed means to estimate time-evolving signal-response relationships without isotope infusion or pathway disruption.

Influence of social network structure on entrepreneurship participation — a study of 20 national

By investigating differences in social networks among entrepreneurs in 20 cultures, this paper contributes to the debate on whether there is universality in the process of entrepreneurial networking. Representative samples of entrepreneurs were identified in the same manner in 20 countries from 2000 to 2004 (N=€‰304,560). The sampling methodologies and the questions asked were similar across all countries. Logistic regression was used to test for significant regional interaction effects involving personally knowing an entrepreneur. Results are contrary to the existence of any mono-dimensional form of networking practice but do strongly support the existence of both variform universality (culture moderates the importance of networking) and functional universality (cultural similarities in networking practice exist).

The emergence of the global workplace : opportunities and barriers for building surveyors in Oceania

The Royal Institution of Chartered Surveyors (RICS) the professional body representing surveyors in the UK, has implemented a policy to globalise in order to meet the challenges and opportunities the global marketplace was creating for its members as well as protecting and serving its interests (RICS, 1999). Quantity surveyors had a presence and history of employment outside the UK, particularly in the Middle and Far East. Real estate surveyors found the transition to working in European Union (EU) countries relatively straightforward and numerous UK real estate organisations have European, Asian, North American and Oceanic offices. Additionally UK based firms establishing partnerships with overseas real estate firms expanded significantly over the previous decade. Building Surveying is different. Small numbers worked in commonwealth countries but in most countries their professional and academic qualifications were not recognised. With the changes implemented by the RICS, this paper examines the barriers and opportunities facing RICS Chartered Building Surveyors (CBS) in Oceania (taken as Australia, New Zealand, Papua New Guinea and Fiji).

A desk top study reviewed the political, economic and sociological variables affecting employment opportunities and professional services which were put to the RICS Oceania Building Surveying Faculty. No previous study had been undertaken to identify the specific barriers and opportunities in Oceania for the BS and this research adopted a census survey of RICS practitioners currently employed in the region and the results form the most comprehensive picture of the current position. The findings are that some of the opportunities and barriers will change in significance over time. The main barriers to growth were perceived as lack of support from a Euro focussed RICS and the difficulties associated with being perceived as outsiders. Opportunities were perceived as emerging in new areas of professional services such as sustainability and energy efficiency.

No va sobre la sangre. Operacion puerto y el fin de la modernidad

EI caso espanol de dopaje conocido como "Operaci6n Puerto" queda enmarcado dentro del
abandono de las antiguas concepciones legales y la construcci6n de un nuevo sistema funcional de alcance global. "Operaci6n Puerto" ilustra el temor de Verner Moeller de que la politica anti dopaje senala el final de la modernidad - donde se elabora y aplica la ley tanto en los tribunales como en los medios de comunicaci6n. OP es el ejemplo perfecto de la distancia existente entre la ret6rica de la crisis mediatica que rodea al dopaje y al ciclismo profesional y la verdadera realidad de los procesos materiales que tienen lugar mientras el ciclismo atraviesa por un proceso global de reajuste estructural y de construcci6n de una nueva cartografla global del ciclismo. La legitimidad se obtiene a traves de la gesti6n de las crisis y de los acontecimientos: la excepci6n, la funcionalidad y el espectaculo bajo una apariencia de guerra justa contra el mal del dopaje

Continuous product innovation : learning behaviours and knowledge management

The research reported in this paper considers Product Innovation from a broader perspective than that of the isolated NPD (New Product Development) project commonly discussed in the literature. In this perspective, Product Innovation is a continuous and cross-functional process involving the sharing and transfer of knowledge within the many steps of the innovation process, and the integration of a growing number of different competencies inside and outside the organisational boundaries. This paper examines two in-depth case studies that were carried out to establish if and how learning occurred within companies developing new products. Based on a model developed as part of a joint Euro-Australian research project, the way in which the selected companies share and transfer knowledge and learning experiences during their product innovation processes have been examined and analysed. This model uses a number of interrelated variables including performance, behaviours and levers to stimulate improvement, contingencies, and learning/innovation capabilities to describe the learning and knowledge transfer in product innovation processes within the case studies. This paper discusses some of the skills the research has identified that managers need to enable their companies to gain a competitive advantage through improved product innovation. The ongoing research has developed, tested and disseminated a computer-based methodology to assess organisational knowledge capture and transfer in the new product development process. The research is part of the Euro-Australian co-operation project known as CIMA (Continuous Improvement and Product Innovation Management).

Knowledge management in continuous product innovation : a contingent approach

There is a growing interest in new organisational forms and integrated managerial and technological approaches supporting companies in continuously innovating their products and processes to survive in a turbulent environment. Successful product innovation will more and more depend upon a company's ability to manage knowledge and integrate a growing number of competencies within and outside the organisational boundaries. These abilities require a complex set of interrelated managerial, technological and organisational conditions that must be designed according to the individual firm's characteristics. This paper aims to identify and analyse the relation between individual firms' contingent variables and managerial approaches to foster knowledge management in product innovation. Evidence is based on a survey of 70 companies, including European and Australian firms, developed within the Euro-Australian cooperation project entitled CIMA (Continuous Improvement for global innovation management).

Intercultural relations in a global world

The exploration of cross-cultural contact in a global and transnational world is essential for understanding how we can learn to live with difference in ways that go beyond tolerance. This book explores such contact in Euro-American/Australian societies as well as non-western multiethnic societies such as China, Malaysia, Indonesia and countries within Easter Europe. The contributors in this book expose the power relations underpinning such encounters as well as explore the possibilities for meaningful dialogue.
