Supporting the development and deployment of sustainable energy technologies through targeted scientific training

Sustainable energy technologies rely heavily on advanced materials and modern engineering controls. These promising new technologies cannot be reliably deployed without ensuring that there is a sufficient “capacity,” i.e., trained technical personnel with the expertise to implement, monitor, and maintain the energy infrastructure. This same capacity is critical to the local development of new technologies, especially those that respond directly to regional priorities, strengths, and needs. One way to build capacity is through targeted programs that integrate the training and development of locals at an advanced technical level. In practical terms, these programs usually produce a small number of highly educated individuals with skills in science and engineering. The goal of Part VI of this book is to highlight contributing factors in successfully operating capacity building programs.

Requirement Of A Diperoxovanadate-Derived Intermediate for the Interdependent Oxidation Of Vanadyl And Nadh

Oxygen release accompanying oxidation of vanadyl by diperoxovanadate was suppressed on addition of NADH. The added NADH was rapidly oxidized, oxygen in the medium was consumed, and the reaction terminated on exhaustion of either NADH or vanadyl. The consumption of oxygen and disappearance of NADH needed small concentrations of diperoxovanadate to initiate and increased with increase in the concentration of vanadyl and NADH or decrease of pH. The products of the reaction were found to be NAD(+) from NADH and vanadate oligomers from vanadyl and oxygen. The reaction was insensitive to catalase and was not dependent on H2O2. The reaction was inhibited by superoxide dismutase, cytochrome c, EDTA, Mn2+, histidine, and DMPO, but not by hydroxyl radical scavengers such as ethanol and benzoate, The ESR spectrum of the reaction mixture showed the presence of the 1:2:2:1 quartet signal typical of a DMPO-OH adduct, but this was not modified by ethanol, This oxygen radical species, possibly of (OV)-O-. type derived from diperoxovanadate, is proposed to have a role in the reactions of oxygen release and NADH oxidation

Exploring university-community partnerships in arts-based service learning with Australian First Peoples and Arts Organizations

In this chapter we focus on the importance of partnerships in arts-based service learning with Australian First Peoples and community arts organizations. Drawing on six years of our own partnership and a wide body of literature, this chapter aims to act as a trigger for further reflection on ways to engage in meaningful partnerships with First Peoples and arts organizations. In particular, the continuum between transactional and transformational types of relationships provides a useful means for understanding our work and for positioning the various benefits and challenges associated with university-community partnerships more broadly.

Flow of metal into the flash gap in the last stages of a plane-strain closed-die forging operation

In closed-die forging the flash geometry should be such as to ensure that the cavity is completely filled just as the two dies come into contact at the parting plane. If metal is caused to extrude through the flash gap as the dies approach the point of contact — a practice generally resorted to as a means of ensuring complete filling — dies are unnecessarily stressed in a high-stress regime (as the flash is quite thin and possibly cooled by then), which reduces the die life and unnecessarily increases the energy requirement of the operation. It is therefore necessary to carefully determine the dimensions of the flash land and flash thickness — the two parameters, apart from friction at the land, which control the lateral flow. The dimensions should be such that the flow into the longitudinal cavity is controlled throughout the operation, ensuring complete filling just as the dies touch at the parting plane. The design of the flash must be related to the shape and size of the forging cavity as the control of flow has to be exercised throughout the operation: it is possible to do this if the mechanics of how the lateral extrusion into the flash takes place is understood for specific cavity shapes and sizes. The work reported here is part of an ongoing programme investigating flow in closed-die forging. A simple closed shape (no longitudinal flow) which may correspond to the last stages of a real forging operation is analysed using the stress equilibrium approach. Metal from the cavity (flange) flows into the flash by shearing in the cavity in one of the three modes considered here: for a given cavity the mode with the least energy requirement is assumed to be the most realistic. On this basis a map has been developed which, given the depth and width of the cavity as well as the flash thickness, will tell the designer of the most likely mode (of the three modes considered) in which metal in the cavity will shear and then flow into the flash gap. The results of limited set of experiments, reported herein, validate this method of selecting the optimum model of flow into the flash gap.

Digital innovation in social marketing: A systematic literature of interventions using digital channels for engagement

Social marketing uses commercial marketing techniques to deliver interventions for social benefit in order to improve quality of life for individuals and communities. Behaviour change is the primary objective of social marketing interventions (Andreasen 2002). The aim of this systematic review is to provide insight into social marketing interventions and their evaluations published in peer-reviewed journals so as to identify the key elements of social marketing employed by these interventions. as well as understand the use of digital channels for engagement.

The Relationship Between University Culture and Climate and Research Scientists’ Spin-off Intentions

Over the past decades, universities have increasingly become involved in entrepreneurial activities. Despite efforts to embrace their 'third mission', universities still demonstrate great heterogeneity in terms of their involvement in academic entrepreneurship. This chapter adopts an institutional perspective to understand how organizational characteristics affect research scientists' entrepreneurial intentions. We study the impact of university culture and climate on entrepreneurial intentions, thereby specifically focusing on intentions to spin off a company. Using a sample of 437 research scientists from Swedish and German universities, our results reveal that the extent to which universities articulate entrepreneurship as a fundamental element of their mission fosters research scientists' spin-off intentions. Furthermore, the presence of university role models positively affects research scientists' propensity to engage in entrepreneurial activities, both directly and indirectly through entrepreneurial self-efficacy. Finally, research scientists working at universities which explicitly reward people for 'third mission' related output show higher levels of spin-off intentions. This study has implications for both academics and practitioners, including university managers and policy makers.

Interaction of carbon monoxide with transition metal surfaces

XPS studies of the interaction of carbon monoxide with surfaces of Fe, Co and Ni indicate that at 300 K, the disproportionation reaction is prominent up to exposures of 103 L giving rise to high surface concentrations of carbon. At higher exposures and higher temperatures, dissociation of carbon monoxide accompanied by the formation of surface oxide layers becomes more prominent. In the case of copper, disproportionation is prominent up to 104 L even at 500 K followed by dissociation at higher exposures. These results are also supported by Auger spectroscopic studies.

Floating row covers and pyriproxyfen help control silverleaf whitefly Bemisia tabaci (Gennadius) Biotype B (Homoptera: Aleyrodidae) in zucchini

In zucchini, the use of row covers until flowering and the insect growth regulator (IGR) pyriproxyfen are effective methods of reducing the number of insects, especially silverleaf whitefly (Bemisia tabaci (Gennadius) Biotype B), on plants. We compared floating row covers (FRCs) up until flowering with silverleaf whitefly (SLW) introduced (FRC + SLW), or not introduced (FRC-only), or with introduction of SLW in open plots (SLW-only), or with introduction of SLW in open plots with IGR (SLW + IGR). FRC increased temperature and humidity compared with the uncovered treatments. Average fruit weight was less (P < 0.01) for the FRC + SLW treatment compared with the other treatments and the percentage of marketable fruit was less for the FRC + SLW than for the other three treatments. This result indicates that the use of either row covers or IGR controls whiteflies, reduces fruit damage and increases the size, weight, and quality of fruit, and may also control other sap-sucking insects. However, if SLW are already present on plants, the use of FRC may reduce predation and favour build up of SLW. Thus, FRC and IGR, if used judiciously, may provide an effective alternative to broad-spectrum pesticides in small-scale cucurbit production.

Re-thinking teacher quality in high-poverty schools in Australia

As is the case globally, Australian schools that serve high-poverty communities most often employ the least experienced, least prepared teachers. Beginning with a discussion of poverty in Australia this chapter draws on 6 years of learnings from Australia's National Exceptional Teachers for Disadvantaged Schools (NETDS) program to examine how social justice can be taught within a mainstream Initial Teacher Education program in an increasingly neoliberal climate where teacher education curriculum around social justice struggles to find a place within the current discourses of quality teaching and its preoccupations with standards, accountability, and high-stakes testing.

Continuous after-the-fact leakage-resilient eCK-secure key exchange

Security models for two-party authenticated key exchange (AKE) protocols have developed over time to capture the security of AKE protocols even when the adversary learns certain secret values. Increased granularity of security can be modelled by considering partial leakage of secrets in the manner of models for leakage-resilient cryptography, designed to capture side-channel attacks. In this work, we use the strongest known partial-leakage-based security model for key exchange protocols, namely continuous after-the-fact leakage eCK (CAFL-eCK) model. We resolve an open problem by constructing the first concrete two-pass leakage-resilient key exchange protocol that is secure in the CAFL-eCK model.

Social audit failure: Legal liability of external auditors

In this chapter, we look at the step beyond reporting, to the external audit or assurance function. The role of any audit engagement is to provide a professional opinion on a set of financial or non-financial assertions reported by an organization's management, based on an agreed evaluative framework. Any such opinion is not a guarantee that the underlying report is free from fraud or misstatement. Where an audit opinion on financial statements is incorrect, this is referred to as an audit failure. Specifically, the textbook definition of audit failure has two components: that the financial statements contain a serious error and that the auditor has failed to detect the error due to the auditor's failure during the audit process.

Copyright, fair use and the Australian Constitution

There has been much debate over recent years about whether Australian copyright law should adopt a fair use doctrine. In this chapter we argue by pointing to the historical record that the incorporation of the term 'copyrights' in the Australian Constitution embeds a notion of balance and fair use in Australian law and that this should be taken into account when interpreting the Australian Copyright Act 1968. English case law in the 18th and 19th centuries developed a principle that copyright infringement did not occur where a person had made a fair use of a work. Fair use was generally established where the defendant had made a productive use that did more than alter the original work for the purpose of evading liability, and where the defendant had made an original contribution to the resulting work. Additionally, fairness was shown by a use that did not supersede or prejudice the market for the original work. At the time of including the copyright power in the Constitution, the UK Parliament’s understanding of “copyrights” included the notion of fair use as it had been developed in U.K. precedent. In this chapter we argue that the work “copyrights” in the Australia Constitution takes its definition from copyright in 1900 and as it has evolved since. Importantly, the word “copyrights” is infused with a particular meaning that incorporates the principle of copyright balance. The constitutional notion of copyright, therefore, is not that of an unlimited power to prevent all copying. Rather, copyright distinguishes between infringing copying and non-infringing copying and grants to the copyright owner only the power to control the former. Non-infringing copying includes well-accepted limitations on the copyright owner’s rights, including the copying of ideas, the copying of public domain works and the copying of insubstantial parts of copyrighted works. In this chapter we argue that non-infringing copying also includes copying to make a fair use of a work. The sections that distinguish infringing copying from non-infringing copying in the Copyright Act 1968 are sections 36(1) and 101(1), which define infringement as the doing, without licence, of an “act comprised in the copyright”. An infringing copy is an act comprised the copyright, whereas a non-infringing copy is not. We argue that space for fair uses of copyrighted works is built into the Copyright Act 1968 through these sections, because a fair use will not produce an infringing copy and so is not an act comprised in the copyright.
