Dialysis-dependency: the reformulated or remnant person

Being dependent on dialysis is a potentially overwhelming experience where life as previously known is permanently altered. A dialysis-dependent individual may reformulate their identify or perceive that they are a remnant if their former self. This paper will explore and expand Morse and Penrod's (1999) model as a useful way to understand how a person might reconstruct their identify. Grounded in a narrative methodology, interviews if those on haemodialysis and peritoneal dialysis were thematically analysed. It was found that dialysis dependency brings an acknowledgment if a lost past, an inescapable present and an unknowable future, filtered through hope and despair. Nurses need to understand the suffering, wrought by such a struggle,to facilitate the positive re-envisioning if those who are dialysis dependent.

The 'Australian settlement' and Australian political thought

Arguments for reshaping political agendas invariably begin from an appraisal of past errors and achievements. Paul Kelly's notion of the 'Australian Settlement' attempts such a task. Kelly identifies a particular ideological and institutional tradition in Australian politics that dominated much of the twentieth century and that is now deemed to have broken down. This article accepts that the notion of a Settlement provides certain insights into the evolution of Australian political thought. Nonetheless, the paper takes issue with the specific content of Kelly's version of the 'Australian Settlement' and indicates how it may be reformulated. It argues that, to the extent that we can speak of a 'Settlement' in Australia, it was one reached on a wider range of key conflicts or cleavages than those to which Kelly refers.

Piercing the decision-making sphere : happiness as the key to real shareholder participation

The purpose of this article is to explain why recent corporate governance reforms and initiatives proclaiming to enhance shareholder participation and elevate shareholder rights, do not go far enough. Indeed, it is suggested that corporate governance polices and reform programs, which have emerged across the world in response to a number of high-profile corporate collapses, act to re-emphasise the limited, 'passive' role which individual shareholders have traditionally experienced in public companies. Although increasing the amount information provided to shareholders about corporate decisions and strategies, and providing shareholders with a greater opportunity to participate in annual general meetings, do go some way in 'empowering' shareholders, it is argued that shareholders essentially remain passive observers, rather than becoming active participants. To become active participants, or corporate governance 'insiders " it is argued that corporate law needs to be directed at piercing the 'decision-making sphere' for individual shareholders in public companies. This involves accommodating an active role for shareholders in the actual decision-making processes of the corporation, rather than simply being informed of decisions that are made and being entitled to veto decisions at the annual general meeting. The second part of the article looks specifically at how the 'oppression' or 'unfair prejudice' remedy, the most commonly used shareholder remedy, is capable - if reformulated so that the pursuit of happiness, rather than vague notions of 'fairness' and 'justice' is the central objective of the remedy - of being used to influence a change of culture within public companies directed at facilitating an active participatory role for shareholders.

What is the value of the arts?

In an age of globalisation, economic restructuring and rampant consumption, the "cultural industries" have come to be viewed as offering a source of social and economic salvation to declining towns, cities and regions. However, it is far from clear to what extent the arts, media and related tourism create employment, wealth, capital and community cohesion. What then is the value of the cultural industries and what concepts can be deployed to answer this question? This paper will report on one effort to devise a theoretical framework to assess the value of the cultural industries in one small Australian city. Drawing on Marxism, Pierre Boudieu and post-modem theory, it will develop a particular concept of "cultural capital" for use in quantifying and qualifying the socio-economic contribution of the cultural industries in Geelong, Victoria. It will argue that by linking Marx to Bourdieu around reformulated notions of "value" and "cultural capital", a theoretically rigorous framework can be distilled to assess and argue for the value of the arts. Such a concept has particular relevance and implications for arts managers.

Would the 'real' girl gamer please stand up? Gender, LAN cafes and the reformulation of the 'girl' gamer.

In this paper we consider the significance of cyber 'LAN' cafeacutes as sites where on and off-line practices meet in way that complicates binary notions of the gendered gamer. Existing research into computer games culture suggests a male dominated environment and points to girls' lower levels of competence and participation in games. Building on recent studies interested in the constitution of gender through engagement with online technologies, we draw on Judith Butler's politics of performative resignification, and conceptualise digital culture as a resource through which 'girl' gamers are mobilised and potentially reformulated, experiencing their gaming identities in contradictory ways, and fragmenting the category 'girl' in the very act of articulating their place in a male dominated gaming culture. It is argued that through the meeting of on and off-line practices, LAN cafeacutes operate as a location that is particularly amenable to reformulative work in relation to gendered gaming identities.

Trust and the social capital necessary for pedagogical reform

Part of the program of educational reform and the change in pedagogy from rote top down instruction to group based and more creative forms of  pedagogy relies on teachers adequately engaging with accepting, and  trusting the reforms and the way subjectivity is reformulated in the  classroom. My essential argument is that if we want to know how Malaysian educational reform will work and what its chances of success are we must focus as much on the issue of trust as we do on pedagogy. The reasons for this are two fold. First, the success of pedagogical reform and the pick up of new forms of pedagogy in the classroom relies on forms of social interaction and aspects of social capital that are different from the types of relationships that characterize a traditional educational setting. Second, a failure to  understand the important social capital that is both a precursor to  pedagogical reform as well as an outcome of it is a failure to understand  both how pedagogical reform can work and what its implications are. If this thesis is correct then we need to focus our research agendas on an area  that is not as well researched. We need to look at the social capital  preconditions for effective teaching and in particular the issue of trust in our  teaching. This paper is an attempt to map out the theoretical issues that  need further elaboration through research.

Economic linkages across commodity futures : hedging and trading implications

We investigate cross-market trading dynamics in futures contracts written on seemingly unrelated commodities that are consumed by a common industry. On the Tokyo Commodity Exchange, we find such evidence in natural rubber (NR), palladium (PA) and gasoline (GA) futures markets. The automobile industry is responsible for more than 50% of global demand for each of these commodities. VAR estimation reveals short-run cross-market interaction between NR and GA, and from NR to PA. Cross-market influence exerted by PA is felt in longer dynamics, with PA volatility (volume) affecting NR (GA) volume (volatility). Our findings are robust to lag-specification, volatility measure, and consistent with full BEKK-GARCH estimation results. Further analysis, which benchmarks against silver futures market, TOCOM index and TOPIX transportation index, confirms that our results are driven by a common industry exposure, and not a commodity market factor. A simple trading rule that incorporates short-run GA and long-run PA dynamics to predict NR return yields positive economic profit. Our study offers new insights into how commodity and equity markets relate at an industry level, and implications for multi-commodity hedging.

Common industry exposure in seemingly unrelated commodities

We propose and document robust evidence of cross-market return, volatility, and volume interactions among futures contracts written seemingly unrelated commodities exposed to a common industry. On the Tokyo Commodity Exchange, we find such evidence in natural rubber (NR), aluminum (AL) and gasoline (GA) futures markets, which are complementary commodities heavily consumed by Japan's automobile industry. Our VAR results indicate that (i) for shorter dynamics, NR and GA volatility both influence AL volatility; GA volume affects NR volatility and volume; the GA market is immune to both NR and AL trading activities; (ii) for longer dynamics, AL volume affects both NR volume and GA volatility; NR volume influences GA volume. These results are robust to lag-specifications, volatility measures and are consistent with full BEKK-GARCH estimates. Further analysis using the silver contract, TOCOM and TOPIX transportation indices, shows that a commodity market factor cannot explain our result. Our results offer insights into how commodity and equity markets relate at an industry level.

Comparison of static and dynamic engine models on the transient performance of a passenger vehicle powertrain

This paper presents experimental and computational results obtained on the Ford Barra 190 4.0 litres I6 gasoline engine and on the Ford Falcon car equipped with this engine. Measurements of steady engine performance, fuel consumption and exhaust emissions were first collected using an automated test facility for a wide range of cam and spark timings vs. throttle position and engine speed. Simulations were performed for a significant number of measured operating points at full and part load by using a coupled Gamma Technologies GT-POWER/GT-COOL engine model for gas exchange, combustion and heat transfer. The fluid model was made up of intake and exhaust systems, oil circuit, coolant circuit and radiator cooling air circuit. The thermal model was made up of finite element components for cylinder head, cylinder, piston, valves and ports and wall thermal masses for pipes. The model was validated versus measured steady state air and fuel flow rates, cylinder pressure parameters, indicated and brake mean effective pressures, and temperature of metal, oil and coolant in selected locations. Computational results agree well with experiments, demonstrating the ability of the approach to produce fairly accurate steady state maps of BMEP and BSFC, as well as to optimize engine operation changing geometry, throttle position, cam and spark timing. Measurements of the transient performance and fuel consumption of the full vehicle were then collected over the NEDC cycle. Simulations were performed by using a coupled Gamma Technologies GT-POWER/GT-COOL/GT-DRIVE model for instantaneous engine gas exchange, combustion and heat transfer and vehicle motion. The full vehicle model is made up of transmission, driveshaft, axles, and car components and the previous engine model. The model was validated with measured fuel flow rates through the engine, engine throttle position, and engine speed and oil and coolant temperatures in selected locations. Instantaneous engine states following a time dependent demand for torque and speed differ from those obtained by interpolating steady state maps of BSFC vs. BMEP and speed. Computational results agree well with experiments, demonstrating the utility of the approach in providing a more accurate prediction of the fuel consumption over test cycles.

Comparing different economic linkages among commodity futures

Gasoline (GA) and kerosene (KO) are extracted from crude oil (CO), such that the three fuel commodities share a chemical link. On the other hand, GA also shares an industrial link with natural rubber (NR) and palladium (PA) as complementary commodities that are heavily consumed by the automobile industry. We contrast the information content embedded in the two economic linkages. Focusing on TOCOM futures contracts written on the five commodities and centering on GA, we confirm that incremental information provided by either CO, KO or NR, PA over a buy-and-hold strategy and a naive forecast, are both statistically and economically significant. While the chemical link forecast is more profitable, a double-link forecast generated from a VECM with two cointegrating vectors (KO-GA and GANR prices) outperforms both single-link forecasts based on risk-adjusted profit net of transaction costs. Further comparisons against the profitability of commodity-based momentum strategies documented in Erb and Harvey (2006) and Miffre and Rallis (2007) show that the double-link forecast holds its own against the most profitable of the 75 momentum strategies considered. This strongly suggests that not only are there incremental profits to be gained from harnessing and combining economic links among commodity futures, the resultant incremental profits are economically significant against other proven commodity-based trading strategies in the existing literature.

Professional training in applied psychology : towards a signature pedagogy for forensic psychology training

Forensic Psychology is a recognised and important sub-specialty of the Psychology discipline. However, after an expansion in the number of training places that were offered when programmes were first developed, recent years have seen these diminish in response to changes in university policies, resulting from reformulated Federal government funding models. In this article, we argue that it is important for the future of specialist areas of professional psychology to not only articulate the core skills and competencies that are associated with specialist practice but also to develop unique and distinctive approaches to teaching and learning signature pedagogies. Based on the premise that forensic psychological practice is, indeed, a distinctive activity that requires different skills and, importantly, different ways of thinking about the work from other areas of professional psychology, it is suggested that professional training in this area should aim to develop a signature pedagogy which combines methods of teaching and learning that have been developed in legal training programmes with principles of problem-based learning.

A behavioural study of consumer boycott

This paper studied sales of BP branded gasoline in the United States of America prior, during and after the 2010 BP Deepwater Horizon oil spill accident. The research was funded by the Centre for Sustainable and Responsible Organisations at Deakin University. In what is perhaps the first behavioral study of consumer boycott using market level data, we found that consumers’ with geographic proximity to the accident were more likely to boycott the BP brand. In States that bordered or were close to the Gulf of Mexico, BP sales experienced a small but significant decline as compared to sales in States farther away. The small effect is surprising. We suspect this may be related to the inelastic nature of the product category and the high degree of product homogeneity within the category. It appears that consumers’ and the media’s vocalized outrage over the Deepwater Horizon accident did not result in significant changes in purchase behavior. As such, while consumers were outraged by BP’s actions, they continued to purchase the BP brand. Consumers who lived farther from the spill did not appear to alter their buying patterns even in the short-term, despite being exposed to similar media coverage and high levels of negative public sentiment. In examining changes in BP brand-share with both positive (i.e., claims of success in dealing with the spill) and negative events (evidence that attempts to stop the spill failed), we observed some associations between these events and changes in buying behavior. In States close to the accident, BP purchases increased with good news, market share declined with bad news. No apparent correlation was seen in States that were farther from the accident.

Energy minimization in multi-task software-defined sensor networks

Abstract—
After a decade of extensive research on application-specific wireless sensor networks (WSNs), the recent development of information and communication technologies makes it practical to realize the software-defined sensor networks (SDSNs), which are able to adapt to various application requirements and to fully explore the resources of WSNs. A sensor node in SDSN is able to conduct multiple tasks with different sensing targets simultaneously. A given sensing task usually involves multiple sensors to achieve a certain quality-of-sensing, e.g., coverage ratio. It is significant to design an energy-efficient sensor scheduling and management strategy with guaranteed quality-of-sensing for all tasks. To this end, three issues are investigated in this paper: 1) the subset of sensor nodes that shall be activated, i.e., sensor activation, 2) the task that each sensor node shall be assigned, i.e., task mapping, and 3) the sampling rate on a sensor for a target, i.e., sensing scheduling. They are jointly considered and formulated as a mixed-integer with quadratic constraints programming (MIQP) problem, which is then reformulated into a mixed-integer linear programming (MILP) formulation with low computation complexity via linearization. To deal with dynamic events such as sensor node participation and departure, during SDSN operations, an efficient online algorithm using local optimization is developed. Simulation results show that our proposed online algorithm approaches the globally optimized network energy efficiency with much lower rescheduling time and control overhead.

Looking back to move forward: the Dymaxion revisited

In 1933 and 1934 the visionary architect, designer, engineer and philosopher Robert Buckminster Fuller built three prototypes of a car he named the Dymaxion. Regarded as a ground breaking concept vehicle, the Dymaxion is arguably more relevant today than when it was conceived over eighty years ago. Although plans to manufacture were abandoned by Chrysler in 1933, the Dymaxion Car was considered the most fuel-efficient car of its time using less than half the amount of gasoline than any other car on the road. This was due to its meticulous design based on scientific first principles, power weight ratios and the laws of aerodynamics. The Dymaxion was spacious and easy to maneuver; it offered multi purpose use options with the passenger capacity of a modern people carrier and represented Buckminster Fuller's social responsibility mantra to create more with less. The brand narrative of the Dymaxion tells a story of sustainability and practicality that resonates with today's vehicle consumer market. The adage suggesting that there is reason why a car's windshield is bigger than its rear view mirror and implies that what lies ahead is much more important than anything behind you. Although this life metaphor acknowledges the importance of an occasional glace back this paper emphasises the strategic value of a precognitive, retrospective approach to design.

Assembled block copolymer stabilized high internal phase emulsion hydrogels for enhancing oil safety

Accidental spills and subsequent fires during oil storage and transportation periods cause serious damage to environments. Herein, we present a novel route to enhance oil safety by transforming oils into high internal phase emulsion (HIPE) hydrogels. These HIPE hydrogels are stabilized by solvent- or pH-driven assembled block copolymer (BCP), namely poly(4-vinylpyridine)-block-poly(ethylene glycol)-block-poly(4-vinylpyridine) (4VPm-EGn-4VPm). The assembled BCP shows high efficiency to stabilize HIPE hydrogels with a low concentration of 1.0 (w/v) % relative to the continuous aqueous phase. The volume fraction of the dispersed organic phase can be as high as 89% with a variety of oils, including toluene, xylene, blended vegetable oil, canola oil, gasoline, diesel, and engine oil. These smelly and flammable liquids were formed into HIPE hydrogels and thus their safety was enhanced. As the assembly is pH sensitive, oils trapped in the HIPE hydrogels can be released by simply tuning pH values of the continuous aqueous phase. The aqueous phase containing BCP can be reused to stabilize HIPE hydrogels after naturalization. These assembled BCP stabilized HIPE hydrogels offer a novel and safe approach to preserve and transport these smelly and flammable liquid oils, avoiding environmental damage.
