The efficacy of an augmented virtual reality system to alleviate pain in children undergoing burns dressing changes : a randomised controlled trial

In children, the pain and anxiety associated with acute burn dressing changes can be severe, with drug treatment alone frequently proving to be inadequate. Virtual reality (VR) systems have been successfully trialled in limited numbers of adult and paediatric burn patients. Augmented reality (AR) differs from VR in that it overlays virtual images onto the physical world, instead of creating a complete virtual world. This prospective randomised controlled trial investigated the use of AR as an adjunct to analgesia and sedation in children with acute burns. Forty-two children (30 male and 12 female), with an age range of 3–14 years (median age 9 years) and a total burn surface area ranging from 1 to 16% were randomised into a treatment (AR) arm and a control (basic cognitive therapy) arm after administration of analgesia and/or sedation. Pain scores, pulse rates (PR), respiratory rates (RR) and oxygen saturations (SaO2) were recorded pre-procedurally, at 10 min intervals and post-procedurally. Parents were also asked to grade their child's overall pain score for the dressing change. Mean pain scores were significantly lower (p = 0.0060) in the AR group compared to the control group, as were parental pain assessment scores (p = 0.015). Respiratory and pulse rates showed significant changes over time within groups, however, these were not significantly different between the two study groups. Oxygen saturation did not differ significantly over time or between the two study groups. This trial shows that augmented reality is a useful adjunct to pharmacological analgesia.

Sustainable and affordable housing : a myth or reality

The Australian government has released a draft National Building Framework that will likely tighten the building standard for new houses to meet higher sustainability requirements. There are uncertainties about the impact this could have on the cost of housing and the supply of affordable housing. This paper aims to provide evidence-based conclusions on the possibility of delivering sustainable and affordable housing for low income people. The case studies are gathered from Brisbane and Gold Coast. Case studies are analysed by unpacking the features that were included to meet sustainability and affordability goals for housing. This paper outlines the key factors for their success and also challenges for replication of the projects. The study shows that the key success drivers for delivering sustainable and affordable housing are providing planning incentives, subsidies for increased energy efficiency, supportive regulatory frameworks and appropriate allocation of infrastructure charges. It shows that government can prioritise their resources to support affordable and sustainable housing for low income people.

Reality bites: When copyright law and reality cooking meet, only the lawyers win

There’s nothing new about this recipe for success: toss in high-stress scenarios, flavour generously with competitive chefs, and garnish with a panel of celebrity judges. With all major broadcasters in the country now dishing up some form of reality cooking programme, Australians could be forgiven for having lost any expectation of original TV material. But that didn’t stop Channel Seven from taking Channel Nine to court last week, arguing its copyright in My Kitchen Rules had been infringed with Nine’s latest prime-time effort, The Hotplate. After the first few episodes went to air, Seven asked for an injunction to stop Nine from broadcasting any more episodes of the reality show. So let’s look at some common confusions about copyright law and how it relates to reality television. Because in this context, copyright infringement isn’t about shows sharing major similarities, or about protecting ideas, but rather the expression of these ideas in the final product. Still, stretching copyright law to protect the “vibe” of a work isn’t good for artists, TV producers or viewers: copyright was designed to nurture creativity, not stifle it.

Maintaining a grasp on reality – Is our validation and design effort focused in the same direction?

This article examines the influence on the engineering design process of the primary objective of validation, whether it is proving a model, a technology or a product. Through the examination of a number of stiffened panel case studies, the relationships between simulation, validation, design and the final product are established and discussed. The work demonstrates the complex interactions between the original (or anticipated) design model, the analysis model, the validation activities and the product in service. The outcome shows clearly some unintended consequences. High fidelity validation test simulations require a different set of detailed parameters to accurately capture behaviour. By doing so, there is a divergence from the original computer-aided design model, intrinsically limiting the value of the validation with respect to the product. This work represents a shift from the traditional perspective of encapsulating and controlling errors between simulation and experimental test to consideration of the wider design-test process. Specifically, it is a reflection on the implications of how models are built and validated, and the effect on results and understanding of structural behaviour. This article then identifies key checkpoints in the design process and how these should be used to update the computer-aided design system parameters for a design. This work strikes at a fundamental challenge in understanding the interaction between design, certification and operation of any complex system.

Democracy Concepts of the Fundamentalist Parties of Algeria and Tunisia – Claim and Reality

This article discusses democratic elements in early Islamic sources and in the programs of the Algerian FIS (Front Islamique du Salut) and ANNAHDA in Tunesia. According to historic writings, Islam includes the principles of democratic consensus, consultation, and freedom of opinion, and an understanding that the sources of Islamic jurisdiction are subject to interpretation, that the sharia can be changed, and that religious authorities’ power to issue instructions on worldly matters is limited. These are the type of expectations that fundamentalist parties arouse when they speak of an Islamic caliphate as a state system. Against this background, an examination of the political system proposed until 1992 by the Algerian FIS shows that this system would have resulted in a very restrictive form of Islam. An investigation of the political system of the Tunisian fundamentalist leader Rached al-Ghannouchi reveals that the system he proposes may be designated as an Islamic democracy, since it takes into account separation of powers and pluralism of political parties. The head of state would be subject to the law in the same manner as the people. However, it is no liberal democracy, as he categorically rejects secularism, intends to punish apostates, and is only willing to allow political parties that are based on the religion of Islam. His state would only be a state of those citizens who follow Islam, completely neglecting secularist groups. Social conflicts and unrest are thus predetermined.

Using Virtual Reality in the teaching of manufacturing processes with material removal in CNC Machine-Tools

This paper presents a methodology for the incorporation of a Virtual Reality development applied to the teaching of manufacturing processes, namely the group of machining processes in numerical control of machine tools. The paper shows how it is possible to supplement the teaching practice through virtual machine-tools whose operation is similar to the 'real' machines while eliminating the risks of use for both users and the machines.

The next step after Japan? (Virtual reality, training and crisis management). Transatlantic Security Paper No. 2, June 2012

The recent crisis in Japan, which combined tsunami and technological events, shows that any crisis, especially those in developed and developing countries, is from here out a hybrid crisis, mixing natural factors and human/technological (NATECH). Faced with such dramatic events, which exceed any means available for emergency rescue service, it is necessary a) to remain prudent and b) to prepare. One of the means for preparing is unquestionably training. However, here, undoubtedly there are important constraints: How to train, for example, while reproducing vividly and realistically, an event? How to exceed the admittedly useful, although very limited, level of the table-top exercise? How also to avoid the unnecessary mobilization of dozens, even hundreds, of field and operation staffers to take part in an exercise which could lead to a disappointing outcome? A major crisis, a major exercise, in effect. The solution of virtual reality has emerged, in Europe and in the United States. It is also sometimes called “serious game”.

Magyarországi „munkavállaló-barát” (employee friendly) szervezetek – Valóság vagy utópia (avagy mit tanulhatunk tőlük?) = The Hungarian employee friendly organizations: reality or Utopia (or what can we learn from them?)

A szerzők feltáró kutatásukban munkavállaló-barát szervezeti megoldásokat kerestek és vizsgáltak multiparadigmikus (Primecz, 2008) megközelítéssel, kritikai és funkcionalista szemszögből. Munkavállalóbarát szervezeti gyakorlatnak tekintették azokat a szervezeti kultúrában gyökerező szervezeti kereteket és gyakorlatokat, amelyek nagymértékben támogatják a munkavállalókat a munka és magánélet egyensúlyának elérésében és megtartásában (Toarniczky et al., 2011). Eredményeik szerint a munkavállaló-barát gyakorlatokat akkor értékelik legjobban a szervezeti tagok, ha a közvetlen vezető és kollégák jól értik a támogatandó munkavállaló helyzetét és rugalmasan fordítják le a hétköznapokra a HR-rendszereket. Ezzel együtt több feszültség keletkezik a szervezetben a munkavállaló-barát gyakorlatokban, amelyekre figyelni lehetne, anélkül, hogy a kialakított gyakorlatokat felszámolnák. _____ The authors in their research investigated employee friendly practices, which they defined as frameworks and practices rooted in organisational culture that gives maximum support for employees trying to reach and keep balance between work and private life (Toarniczky et al., 2011) through multiparadigm research (Primecz, 2008). They conducted exploratory research (interviews, focus groups, document-analysis, and questionnaire) at ten Hungarian-based organizations, and they investigated employee friendly work practices through functionalist and critical lenses. Their results shows that employee friendly practices work well, when the immediate boss and colleagues understand the need of organization al member, who are supported, and HR procedures are translated flexibly. At the same time tension within the organization al subgroups always present, and this should be handled by the organization without cancelling employee friendly practices.

Autoethnography : critical appreciation of an emerging art

In this article, the author discusses how she applied autoethnography in a study of the design of hypermedia educational resources and shows how she addressed problematic issues related to autoethnographic legitimacy and representation. The study covered a 6-year period during which the practitioner’s perspective on the internal and external factors influencing the creation of three hypermedia CD-ROMs contributed to an emerging theory of design. The author highlights the interrelationship between perception and reality as vital to qualitative approaches and encourages researchers to investigate their reality more fully by practicing the art of autoethnography.

Linking Theory and Practice: Performing a Reality Check on a Model of IS Success

The issue of ‘rigour vs. relevance’ in IS research has generated an intense, heated debate for over a decade. It is possible to identify, however, only a limited number of contributions on how to increase the relevance of IS research without compromising its rigour. Based on a lifecycle view of IS research, we propose the notion of ‘reality checks’ in order to review IS research outcomes in the light of actual industry demands. We assume that five barriers impact the efficient transfer of IS research outcomes; they are lack of awareness, lack of understandability, lack of relevance, lack of timeliness, and lack of applicability. In seeking to understand the effect of these barriers on the transfer of mature IS research into practice, we used focus groups. We chose DeLone and McLean’s IS success model as our stimulus because it is one of the more widely researched areas of IS.
