Mandatory sentencing : a criminological perspective

This paper will give a ‘criminological perspective’ on mandatory sentencing. It will however largely avoid the issues of the effect of mandatory sentencing provisions on the judicial process and judicial independence, as this has already been covered by Sir Anthony Mason. It will also avoid the legal issues concerning the constitutional, human rights and international law aspects of mandatory sentencing which will be covered by later speakers. The aim will be to give a brief overview of research which evaluates the effects of mandatory sentencing provisions in terms of the available evidence of whether they meet their stated aims of deterrence, selective incapacitation and the reduction of crime rates. This will be done in two parts, first in relation to the more extensive experiment in mandatory sentencing in the USA which has provided some of the impetus and metaphors ("three strikes") for recent Australian developments; and second the recent mandatory sentencing provisions in Western Australia (WA) and the Northern Territory (NT). Evidence from both the US and WA (NT is hard to assess because of the lack of proper monitoring and criminal statistics) indicates that mandatory sentencing does not produce the effects of deterrence, selective incapacitation and crime reduction which are its stated justifications and does produce a range of damaging side effects in terms of distortion of the judicial process, wildly disproportionate sentencing, additional financial and social cost and deepening social exclusion of individuals and particular communities. So what is left are the less acknowledged underpinnings of mandatory sentencing in the form of the symbolic politics of law and order, the politics of social exclusion and a displacement of racial anxieties and hostilities onto the terrain of the legal. In fashioning this necessarily brief overview a number of sources have been heavily drawn upon, in particular the excellent work by Neil Morgan from UWA (Morgan, 1995;1999; 2000); Dianne Johnson and George Zdenkowski in their detailed report to the Senate Inquiry (2000); and a number of articles appearing in 1999 in an excellent special issue of the UNSW Law Journal, all of which are highly recommended for further reading.

'The Australian we all aspire to be' : commemorative journalism and the death of the Crocodile Hunter

This article examines the news coverage the death of Steve Irwin, widely known as the Crocodile Hunter, generated in Australia. In line with past research on commemorative journalism, the study demonstrates the dominant discourses employed in the reporting of Irwin's death. It is argued that Australia's newspapers invoked a number of national myths, such as mateship, larrikinism and anti-elitism, in order to re-assert notions of Australian identity and social values and to deal with the grief over his loss. Most importantly, the study sheds new light on how news media deal with challenges to the dominant memorialising discourse. Past studies had not been able to investigate in much detail alternative discourses, but in examining Irwin's death, we are able to see how the media deal with such an unwanted interruption. It is argued that newspapers appropriated the alternative perspective within the mythical terms of their memorialising discourse, thereby not allowing it to disrupt the memorialisation itself and in fact further strengthening the process of mythologising the Crocodile Hunter.

Voltage unbalance reduction in low voltage feeders by dynamic switching of residential customers among three phases

Low voltage distribution feeders with large numbers of single phase residential loads experience severe current unbalance that often causes voltage unbalance problems. The addition of intermittent generation and new loads in the form of roof top photovoltaic generation and electric vehicles makes these problems even more acute. In this paper, an intelligent dynamic residential load transfer scheme is proposed. Residential loads can be transferred from one phase to another phase to minimize the voltage unbalance along the feeder. Each house is supplied through a static transfer switch with three-phase input and single-phase output connection. The main controller, installed at the transformer will observe the power consumption in each load and determine which house(s) should be transferred from one phase to another in order to keep the voltage unbalance in the feeder at a minimum. The efficacy of the proposed load transfer scheme is verified through MATLAB and PSCAD/EMTDC simulations.

Acoustic Masking of a Stealthy Outdoor Robot Tracking a Dynamic Target

This work is motivated by the desire to covertly track mobile targets, either animal or human, in previously unmapped outdoor natural environments using off-road robotic platforms with a non-negligible acoustic signature. The use of robots for stealthy surveillance is not new. Many studies exist but only consider the navigation problem to maintain visual covertness. However, robotic systems also have a significant acoustic footprint from the onboard sensors, motors, computers and cooling systems, and also from the wheels interacting with the terrain during motion. All these can jepordise any visual covertness. In this work, we experimentally explore the concepts of opportunistically utilizing naturally occurring sounds within outdoor environments to mask the motion of a robot, and being visually covert whilst maintaining constant observation of the target. Our experiments in a constrained outdoor built environment demonstrate the effectiveness of the concept by showing a reduced acoustic signature as perceived by a mobile target allowing the robot to covertly navigate to opportunistic vantage points for observation.

Where are all the female participants in sports and exercise medicine research?

The aim of this study is to estimate the ratio of male and female participants in Sports and Exercise Medicine research. Original research articles published in three major Sports and Exercise Medicine journals (Medicine and Science in Sport and Exercise, British Journal of Sports Medicine and American Journal of Sports Medicine) over a three year period were examined. Each article was screened to determine the following: total number of participants, the number of female participants and the number of male participants. The percentage of females and males per article in each of the journals was also calculated. Cross tabulations and Chi square analysis were used to compare the gender representation of participants within each of the journals. Data were extracted from 1, 382 articles involving a total of 6, 076, 705 participants. 2, 366, 998 (39%) participants were female and 3, 709, 707 (61%) male. The average percentage of female participants per article across the journals ranged from 35-37%. Females were significantly under-represented across all of the journals (X2 =23566, df=2, p<0.00001). There were no significant differences between the three journals. In conclusion, Sports and Exercise Medicine practitioners should be cognisant of sexual dimorphism and gender disparity in the current literature.

All the worldwide web's a stage : teenage girls' self-presentation and identities formation through status updates

This study investigates grade eight girls’ use of status updates on Facebook in order to create identities online. Using sociologist Erving Goffman’s theory of self-presentation as a framework, Jones and Pittman’s subsequent strategies of self-presentation are used to discover the ways in which teenage girls use status updates in order to create identities online and manage audience impressions. Using a mixed methods design, the results showed that, while existing self-presentation strategies persist, social networking has created new means of self-presentation. This study adds to a growing pool of research regarding teens’ engagement with social networking websites to form identities.

Constrained control design for dynamic positioning of marine vehicles with control allocation

In this paper, we address the control design problem of positioning of over-actuated marine vehicles with control allocation. The proposed design is based on a combined position and velocity loops in a multi-variable anti-windup implementation together with a control allocation mapping. The vehicle modelling is considered with appropriate simplifications related to low-speed manoeuvring hydrodynamics and vehicle symmetry. The control design is considered together with a control allocation mapping. We derive analytical tuning rules based on requirements of closed-loop stability and performance. The anti- windup implementation of the controller is obtained by mapping the actuator-force constraint set into a constraint set for the generalized forces. This approach ensures that actuation capacity is not violated by constraining the generalized control forces; thus, the control allocation is simplified since it can be formulated as an unconstrained problem. The mapping can also be modified on-line based on actuator availability to provide actuator-failure accommodation. We provide a proof of the closed-loop stability and illustrate the performance using simulation scenarios for an open-frame underwater vehicle.

A survey of control allocation methods for underwater vehicles

A control allocation system implements a function that maps the desired control forces generated by the vehicle motion controller into the commands of the different actuators. In this article, a survey of control allocation methods for over-actuated underwater vehicles is presented. The methods are applicable for both surface vessels and underwater vehicles. The paper presents a survey of control allocation methods with focus on mathematical representation and solvability of thruster allocation problems. The paper is useful for university students and engineers who want to get an overview of state-of-the art control allocation methods as well as advance methods to solve more complex problems.

The Australian Nonprofit Sector Legal and Accounting Almanac 2013

INTRODUCTION CASES For a number of years, Professor Myles McGregor-Lowndes, Frances Hannah and Anne Overell have compiled one to two page summaries of cases involving nonprofit organisations and published them on The Australian Centre for Philanthropy and Nonprofit Studies, Developing Your Organisation (DYO) website.1 You can be alerted of new case summaries as they are posted to the DYO website by subscribing to the ACPNS RSS feed or the ACPNS twitter service.2 There were some very significant cases during 2013, such as Commissioner of Taxation v Cancer & Bowel Research Association (see case notes 2.8.2 and 2.8.11), The Hunger Project case which is under appeal, but could change the face of PBI jurisprudence (see case note 2.8.7) while Home Health Pty Ltd retained the PBI status quo but might have been different if appealed (see case note 2.8.8). For sheer interest there is nothing better in my 30 odd years of reading tax and charity judgements than case involving The Study and Prevention of Psychological Diseases Foundation Incorporated (see case note 2.1.1). It even rivals some of the more bizarre cases from the US jurisdiction of which St Joseph Abbey v Castille (case note 2.10.9) is certainly ‘dead centre’. A set of cases which stand out for attention are those involving New Zealand’s Christchurch Cathedral which anyone with responsibility for heritage-listed buildings should study carefully, for implications in relation to their own circumstances. A number of cases summarised in this Almanac are working their way through the appeals process and care should be taken with their application. In addition, some of the cases are from jurisdictions outside Australia, and readers should exercise caution when considering the implications of these cases for Australian law. LEGISLATION The Almanac includes a review of major statutory amendments during 2013, which are relevant to the nonprofit sector in all Australian jurisdictions. Special thanks must go to Nathan MacDonald and the JusticeConnect team for providing legislative updates for Victoria. SPECIAL ISSUES DURING 2013 A number of legal practitioners have contributed articles on significant legal issues facing nonprofit organisations: charitable trusts giving to government entities (Alice Macdougall); workplace bullying (Tim Longwill); and privacy (James Tan and Nina Brewer). WORLD ROUND-UP Major developments from the UK and Ireland (Kerry O’Halloran), Canada (Peter Broder), New Zealand (Michael Gousmett and Susan Barker) and Jamaica (Frances Hannah) are all summarised in a review of a significant part of the common law charity jurisdictions. WHAT DOES 2014 HOLD The final section moves from looking in the rear view mirror to peering out the front windscreen to discern the reform agenda. The view from the windscreen in 2013 was of considerable reform traffic at the Commonwealth level jostling for a place in the parliamentary agenda. This year is quite different with a smaller number of vehicles ahead, but the potential for significant impact.

Lying in all honesty : capturing truth in women’s confessional memoir

This paper explores the slippery nature of illness and diagnosis in Lauren Slater’s memoir, Lying: a Metaphorical Memoir (2000). Speaking from the shadowy intersection of childhood and adolescence, Slater’s narrator, Lauren, uses the metaphor of epilepsy to describe her own predilection for exaggeration. In exploiting the fallibility of the first-person narrator, Slater insists on the legitimacy of metaphor in accounts of childhood illness that are more concerned with narrative truth than historical accuracy. The result of this playfulness and general misrule is that Slater writes herself into a double bind: on one side, she is the child narrator who inadvertently misrepresents events and misdirects readers, and on the other side, she is the untrustworthy author who employs metaphor as a licence to lie.

Whole System Design : An Integrated Approach to Sustainable Engineering

Whole System Design is increasingly being seen as one of the most cost effective ways to both increase the productivity and reduce the negative environmental impacts of an engineered system. A focus on design is critical, as the output from this stage of the project locks-in most of the economic and environmental performance of the designed system throughout its life, which can span from a few years to many decades. Indeed, it is now widely acknowledged that all designers – particularly engineers, architects and industrial designers – need to be able to understand and implement a whole system design approach. This book provides a clear design methodology, based on leading efforts in the field, and is supported by worked examples that demonstrate how advances in energy, materials and water productivity can be achieved through applying an integrated approach to sustainable engineering. Chapters 1–5 outline the approach and explain how it can be implemented to enhance the established Systems Engineering framework. Chapters 6–10 demonstrate, through detailed worked examples, the application of the approach to industrial pumping systems, passenger vehicles, electronics and computer systems, temperature control of buildings, and domestic water systems.

Use of cadavers and anthropometric test devices (ATDs) for assessing lower limb injury outcome from under‐vehicle explosions

Lower extremities are particularly susceptible to injury in an under‐vehicle explosion. Operational fitness of military vehicles is assessed through anthropometric test devices (ATDs) in full‐scale blast tests. The aim of this study was to compare the response between the Hybrid‐III ATD, the MiL‐Lx ATD and cadavers in our traumatic injury simulator, which is able to replicate the response of the vehicle floor in an under‐vehicle explosion. All specimens were fitted with a combat boot and tested on our traumatic injury simulator in a seated position. The load recorded in the ATDs was above the tolerance levels recommended by NATO in all tests; no injuries were observed in any of the 3 cadaveric specimens. The Hybrid‐III produced higher peak forces than the MiL‐Lx. The time to peak strain in the calcaneus of the cadavers was similar to the time to peak force in the ATDs. Maximum compression of the sole of the combat boot was similar for cadavers and MiL‐Lx, but significantly greater for the Hybrid‐III. These results suggest that the MiL‐Lx has a more biofidelic response to under‐vehicle explosive events compared to the Hybrid‐III. Therefore, it is recommended that mitigation strategies are assessed using the MiL‐Lx surrogate and not the Hybrid‐III.

Thermodynamic modeling of ethanol fumigation in a diesel engine

Due to rapidly diminishing international supplies of fossil fuels, such as petroleum and diesel, the cost of fuel is constantly increasing, leading to higher costs of living, as a result of the significant reliance of many industries on motor vehicles. Many technologies have been developed to replace part or all of a fossil fuel with bio-fuels. One of the dual fuel technologies is fumigation of ethanol in diesel engines, which injects ethanol into the intake air stream of the engine. The advantage of this is that it avoids any costly modification of the engine high pressure diesel injection system, while reducing the volume of diesel required and potentially increasing the power output and efficiency. This paper investigates the performance of a diesel engine, converted to implement ethanol fumigation. The project will use both existing experimental data, along with generating computer modeled results using the program AVL Boost. The data from both experiments and the numerical simulation indicate desirable results for the peak pressure and the indicated mean effective pressure (IMEP). Increase in ethanol substitution resulted in elevated combustion pressure and an increase in the IMEP, while the variation of ethanol injection location resulted in negligible change. These increases in cylinder pressure led to a higher work output and total efficiency in the engine as the ethanol substitution was increased. In comparing the numerical and experimental results, the simulation showed a slight elevation, due to the inaccuracies in the heat release models. Future work is required to improve the combustion model and investigate the effect of the variation of the location of ethanol injection.

Numerical simulation of idealised three-dimensional downburst wind fields

Convective downburst wind storms generate the peak annual gust wind speed for many parts of the non-cyclonic world at return periods of importance for ultimate limit state design. Despite this there is little clear understanding of how to appropriately design for these wind events given their significant dissimilarities to boundary layer winds upon which most design is based. To enhance the understanding of wind fields associated with these storms a three-dimensional numerical model was developed to simulate a multitude of idealised downburst scenarios and to investigate their near-ground wind characteristics. Stationary and translating downdraft wind events in still and sheared environments were simulated with baseline results showing good agreement with previous numerical work and full-scale observational data. Significant differences are shown in the normalised peak wind speed velocity profiles depending on the environmental wind conditions in the vicinity of the simulated event. When integrated over the height of mid- to high rise structures, all simulated profiles are shown to produce wind loads smaller than an equivalent 10 m height matched open terrain boundary layer profile. This suggests that for these structures the current design approach is conservative from an ultimate loading standpoint. Investigating the influence of topography on the structure of the simulated near-ground downburst wind fields, it is shown that these features amplify wind speeds in a manner similar to that expected for boundary layer winds, but the extent of amplification is reduced. The level of reduction is shown to be dependent on the depth of the simulated downburst outflow.
