Could mobile telephony be harnessed for development in Papua New Guinea?

Could mobile telephony be harnessed for development in Papua New Guinea (PNG)? Could mobile phones be utilised to enhance the security and prosperity of rural communities? Could mobile phones be a useful tool in the achievement of the PNG 2050 Vision targets? This paper is based on literature review around use of mobile phones in development in Asia, Africa, and the Caribbean. It also draws on discussions with key players in PNG, such as NGOs, UN agencies, donor partners, telecommunication companies and the government of PNG. Anticipated benefits of mobile phone availability have not been fully realised in rural areas of PNG to date due to pricing, difficulties with recharging handset batteries in communities which do not have mains electricity supply, and also concerns about negative social changes related to mobile telephony, for example parental stress over youth forming unsuitable relationships. Nonetheless, there are manifest possible ways for mobile phone technology to change user communication patterns positively regarding economic output. In sectors as diverse as health, education and law and justice, discussions are currently underway to establish how mobile phones could be used to increase service delivery, particularly to rural and marginal communities.

Key distribution mechanisms for wireless sensor networks : a survey

Advances in technology introduce new application areas for sensor networks. Foreseeable wide deployment of mission critical sensor networks creates concerns on security issues. Security of large scale densely deployed and infrastructure less wireless networks of resource limited sensor nodes requires efficient key distribution and management mechanisms. We consider distributed and hierarchical wireless sensor networks where unicast, multicast and broadcast type of communications can take place. We evaluate deterministic, probabilistic and hybrid type of key pre-distribution and dynamic key generation algorithms for distributing pair-wise, group-wise and network-wise keys.

Trends in cycling patterns and interactions with pedestrians in the city centre

All levels of government continue to advocate increasing the number of people cycling for recreation and transport. However, governments and the general public still have concerns about the implications for the safety of cyclists and other road users. While there is concern about injury for bicycle-pedestrian collisions, for 2008-09 in Australia only 40 pedestrians were hospitalised as a result of a collision with a cyclist (and 33 cyclists from collisions with pedestrians). There is little research that observes changes over time in actual cyclist behaviours and interactions with other road users. This paper presents the results of an observational study of cycling in the Brisbane Central Business District based on data collected using the same methodology in October 2010 and 2012.

Designing an information accountability framework for eHealth

Information privacy is a crucial aspect of eHealth. Appropriate privacy management measures are therefore essential for its success. However, traditional measures for privacy preservation such as rigid access controls (i.e., preventive measures) are not suitable to eHealth because of the specialised and information - intensive nature of healthcare itself, and the nature of the information. Healthcare professionals (HCP) require easy, unrestricted access to as much information as possible towards making well - informed decisions. On the other end of the scale however, consumers (i.e., patients) demand control over their health information and raise concerns for privacy arising from internal activities (i.e., information use by HCPs). A proper balance of these competing concerns is vital for the implementation of successful eHealth systems. Towards reaching this balance, we propose an information accountability framework (IAF) for eHealth systems.

The role of representative design in talent development : a comment on “Talent identification and promotion programmes of Olympic athletes”

A recent comment in the Journal of Sports Sciences (MacNamara & Collins, 2011) highlighted some major concerns with the current structure of talent identification and development (TID) programmes of Olympic athletes (e.g. Gulbin, 2008; Vaeyens, Gullich, Warr, & Philippaerts, 2009). In a cogent commentary, MacNamara and Collins (2011) provided a short review of the extant literature, which was both timely and insightful. Specifically, they criticised the ubiquitous one-dimensional ‘physically-biased’ attempts to produce world class performers, emphasising the need to consider a number of key environmental variables in a more multi-disciplinary perspective. They also lamented the wastage of talent, and alluded to the operational and opportunistic nature of current talent transfer programmes. A particularly compelling aspect of the comment was their allusion to high profile athletes who had ‘failed’ performance evaluation tests and then proceeded to succeed in that sport. This issue identifies a problem with current protocols for evaluating performance and is a line of research that is sorely needed in the area of talent development. To understand the nature of talent wastage that might be occurring in high performance programmes in sport, future empirical work should seek to follow the career paths of ‘successful’ and ‘unsuccessful’ products of TID programmes, in comparative analyses. Pertinent to the insights of MacNamara and Collins (2011), it remains clear that a number of questions have not received enough attention from sport scientists interested in talent development, including: (i) why is there so much wastage of talent in such programmes? And (ii), why are there so few reported examples of successful talent transfer programmes? These questions highlight critical areas for future investigation. The aim of this short correspondence is to discuss these and other issues researchers and practitioners might consider, and to propose how an ecological dynamics underpinning to such investigations may help the development of existing protocols...

The need for ‘representative task design’ in evaluating efficacy of skills tests in sport : a comment on Russell, Benton and Kingsley (2010)

Russell, Benton and Kingsley (2010) recently suggested a new association football test comprising three different tasks for the evaluation of players' passing, dribbling and shooting skills. Their stated intention was to enhance ‘ecological validity’ of current association football skills tests allowing generalisation of results from the new protocols to performance constraints that were ‘representative’ of experiences during competitive game situations. However, in this comment we raise some concerns with their use of the term ‘ecological validity’ to allude to aspects of ‘representative task design’. We propose that in their paper the authors confused understanding of environmental properties, performance achievement and generalisability of the test and its outcomes. Here, we argue that the tests designed by Russell and colleagues did not include critical sources of environmental information, such as the active role of opponents, which players typically use to organise their actions during performance. Static tasks which are not representative of the competitive performance environment may lead to different emerging patterns of movement organisation and performance outcomes, failing to effectively evaluate skills performance in sport.

Problems and awareness of support services among University students

Although Australian universities have allocated significant resources toward the development of student support services, administrators have little systematic information about the problems undergraduate university students experience or students' knowledge about available support services. The author surveyed 441 students in an urban, nonresidential university to examine the prevalence of difficulties associated with learning, sexual harassment, discrimination, emotional distress, health problems, course and career concerns, financial difficulties, and difficulties with lecturers; he also assessed students' knowledge of support services in each of these areas. Course concerns were the most common problem, followed by emotional distress, worry about career choices, financial difficulties, and problems with lecturers. More than half of the students were unaware of the support services available to them to address a range of concerns from sexual harassment and discrimination to emotional distress. Approximately 20% of the students reported having used university counseling or career services. Implications for targeting specific areas for outreach programs are discussed.

Personal Injuries Proceedings Act 2002 s 27(1) – duty of respondent to give information and documents

In Hare v Mount Isa City Council [2009] QDC 39 McGill DCJ examined the scope of s 27(1) of the Personal Injuries Proceedings Act 2002 (Qld) and its interpretation by the Court of Appeal in Haug v Jupiters Ltd [2008] 1 Qd R 276. The judge expressed a number of concerns about the Act and the Regulation made under it, that are worthy of consideration by the Legislature.

Efficient querying of large process model repositories

Recent years have seen an increased uptake of business process management technology in industries. This has resulted in organizations trying to manage large collections of business process models. One of the challenges facing these organizations concerns the retrieval of models from large business process model repositories. For example, in some cases new process models may be derived from existing models, thus finding these models and adapting them may be more effective and less error-prone than developing them from scratch. Since process model repositories may be large, query evaluation may be time consuming. Hence, we investigate the use of indexes to speed up this evaluation process. To make our approach more applicable, we consider the semantic similarity between labels. Experiments are conducted to demonstrate that our approach is efficient.

Riding a mile in their shoes : understanding Australian metropolitan rail passenger perceptions and experiences of crowdedness using mixed-methods research

Metrics such as passengers per square metre have been developed to define optimum or crowded rail passenger density. Whilst such metrics are important to operational procedures, service evaluation and reporting, they fail to fully capture and convey the ways in which passengers experience crowded situations. This paper reports findings from a two year study of rail passenger crowding in five Australian capital cities which involved a novel mixed-methodology including ethnography, focus groups and an online stated preference choice experiment. The resulting data address the following four fundamental research questions: 1) to what extent are Australian rail passengers concerned by crowding, 2) what conditions exacerbate feelings of crowdedness, 3) what conditions mitigate feelings of crowdedness, and 4) how can we usefully understand passengers’ experiences of crowdedness? It concludes with some observations on the significance and implications of these findings for customer service provision. The findings outlined in this paper demonstrate that the experience of crowdedness (including its tolerance) cannot be understood in isolation from other customer services issues such as interior design, quality of environment, safety and public health concerns. It is hypothesised that tolerance of crowding will increase alongside improvements to overall customer service. This was the first comprehensive study of crowding in the Australian rail industry.

Submission to National Inquiry into Children in Immigration Detention from The Australian Psychological Society

Executive Summary The Australian Psychological Society categorically condemns the practice of detaining child asylum seekers and their families, on the grounds that it is not commensurate with psychological best practice concerning children’s development and mental health and wellbeing. Detention of children in this fashion is also arguably a violation of the UN Convention on the Rights of the Child. A thorough review of relevant psychological theory and available research findings from international research has led the Australian Psychological Society to conclude that: • Detention is a negative socialisation experience. • Detention is accentuates developmental risks. • Detention threatens the bonds between children and significant caregivers. • Detention limits educational opportunities. • Detention has traumatic impacts on children of asylum seekers. • Detention reduces children’s potential to recover from trauma. • Detention exacerbates the impacts of other traumas. • Detention of children from these families in many respects is worse for them than being imprisoned. In the absence of any indication from the Australian Government that it intends in the near future to alter the practice of holding children in immigration detention, the Australian Psychological Society’s intermediate position is that the facilitation of short-term and long-term psychological development and wellbeing of children is the basic tenet upon which detention centres should be audited and judged. Based on that position, the Society has identified a series of questions and concerns that arise directly from the various psychological perspectives that have been brought to bear on estimating the effects of detention on child asylum seekers. The Society argues that, because these questions and concerns relate specifically to improvement and maintenance of child detainees’ educational, social and psychological wellbeing, they are legitimate matters for the Inquiry to consider and investigate. • What steps are currently being taken to monitor the psyc hological welfare of the children in detention? In particular, what steps are being taken to monitor the psychological wellbeing of children arriving from war-torn countries? • What qualifications and training do staff who care for children and their families in detention centres have? What knowledge do they have of psychological issues faced by people who have been subjected to traumatic experiences and are suffering high degrees of anxiety, stress and uncertainty? • What provisions have been made for psycho-educational assessment of children’s specific learning needs prior to their attending formal educational programmes? • who are suffering chronic and/or vicarious trauma as a result of witnessing threatening behaviour whilst in detention? • What provisions have been made for families who have been seriously affected by displacement to participate in family therapy? • What critical incident debriefing procedures are in place for children who have witnessed their parents, other family members, or social acquaintances engaging in acts of self-harm or being harmed while in detention? What psychotherapeutic support is in place for children who themselves have been harmed or have engaged in self- harmful acts while in detention? • What provisions are in place for parenting programmes that provide support for parents of children under extremely difficult psychological and physical circumstances? • What efforts are being made to provide parents with the opportunity to model traditional family roles for children, such as working to earn an income, meal preparation, other household duties, etc.? • What opportunities are in place for the assessment of safety issues such as bullying, and sexual or physical abuse of children or their mothers in detention centres? • How are resources distributed to children and families in detention centres? • What socialization opportunities are available either within detention centres or in the wider community for children to develop skills and independence, engage in social activities, participate in cultural traditions, and communicate and interaction with same-age peers and adults from similar ethnic and religious backgrounds? • What access do children and families have to videos, music and entertainment from their cultures of origin? • What provisions are in place to ensure the maintenance of privacy in a manner commensurate with usual cultural practice? • What is the Government’s rationale for continuing to implement a policy of mandatory detention of child asylum seekers that on the face of it is likely to have a pernicious impact on these children’s mental health? • In view of the evidence on the potential long-term impact of mandatory detention on children, what processes may be followed by Government to avoid such a practice and, more importantly, to develop policies and practices that will have a positive impact on these children’s psychological development and mental health?

Psychological wellbeing of refugees resettling in Australia : a literature review prepared for the Australian Psychological Society

This literature review was developed as background for the formulation of an Australian Psychological Society position on the mental health and wellbeing of refugees resettling in Australia. The major aim is to provide a broad overview of the concerns related to refugee mental health and wellbeing within the Australian context. To begin, a brief overview of the definition of a refugee and the scope of refugee movement is provided. Next, the review examines the pre-displacement, post-displacement, systemic and socio-political factors that influence the process of adaptation in refugee resettlement. It then reviews documented approaches to psychological assessment and therapeutic interventions with refugees; and finally it summarises suggestions for assessment and intervention in these practice contexts.

The role of human factors when evaluating information accountability for eHealth systems

The availability of health information is rapidly increasing; its expansion and proliferation is inevitable. At the same time, breeding of health information silos is an unstoppable and relentless exercise. Information security and privacy concerns are therefore major barriers in the eHealth socio-eco system. We proposed Information Accountability as a measurable human factor that should eliminate and mitigate security concerns. Information accountability measures would be practicable and feasible if legislative requirements are also embedded. In this context, information accountability constitutes a key component for the development of effective information technology requirements for health information system. Our conceptual approach to measuring human factors related to information accountability in eHealth is presented in this paper with some limitations.

Studies in power hardware in the loop (PHIL) simulation using real-time digital simulator (RTDS)

In power hardware in the loop (PHIL) simulations, a real-time simulated power system is interfaced to a piece of hardware, usually called hardware under test (HuT). A PHIL test can be realized using several simulation tools. Among them Real Time Digital Simulator (RTDS) is an ideal tool to perform complex power system simulations in near real-time. Stable operation of the entire system, along with the accuracy of simulation results are the main concerns regarding a PHIL simulation. In this paper, a simulated power network on RTDS will be interfaced to HuT through a voltage source converter (VSC). Issues around stability and other interface problems are studied and a new method to stabilize some unstable PHIL cases is proposed. PHIL simulation results in PSCAD and RSCAD are presented.

Critical discourse analysis and political economy of communication : understanding the new corporate order

This article uses critical discourse analysis to analyse material shifts in the political economy of communications. It examines texts of major corporations to describe four key changes in political economy: (1) the separation of ownership from control; (2) the separation of business from industry; (3) the separation of accountability from responsibility; and (4) the subjugation of ‘going concerns’ by overriding concerns. The authors argue that this amounts to a political economic shift from traditional concepts of ‘capitalism’ to a new ‘corporatism’ in which the relationships between public and private, state and individual interests have become redefined and obscured through new discourse strategies. They conclude that the present financial and regulatory ‘crisis’ cannot be adequately resolved without a new analytic framework for examining the relationships between corporation, discourse and political economy.
