Design + ethics

The socio-cultural purpose of the university has been de-emphasised in recent decades, however, various community engagement projects that have been undertaken by design schools in higher education institutions are bringing this back into focus. Through the design skills of academic staff and students, a number of projects have been identified and undertaken in partnership with communities as well as the public and private sectors. The 2008 ‘Linking Karumba’ project, among others, shows that academy-based design and education professionals can contribute to social development through making good design accessible to disadvantaged communities.

Changing relationships : engaging students and staff in the design studio

QUT Learning and Teaching Unit Seminar Making a Real Difference: Learning and Teaching Grants Showcase This event recognised and shared teaching innovations, including those from faculty learning and teaching grants. The Showcase featured four ALTC Grant project leaders (Helen Partridge, Sylvia Edwards, Robyn Nash and Mary Ryan) who had recently completed or were about to complete their grants. Each QUT faculty nominated two 2010 faculty teaching and learning grant recipients to showcase grant outcomes via a poster. Poster: Shannon Satherley & Abbe Winter Changing Relationships: Engaging Students and Staff in the Design Studio 'In the design studio learning environment, traditional student and staff expectations are of close contact teaching and learning. However, in recent years increasing class sizes have meant students experiencing reduced personal staff attention, and increasingly feeling “anonymous” and correspondingly disengaged, to the detriment of quality learning (Carbone 1998: 8; Biggs 2003). Concurrently, there has been a necessary increase in teaching by sessional (casual) teaching staff at QUT, with varied levels of experience and assurance. While teachers primarily regard engagement as “cognitive and conative,” for students it is emotional: “... an essential need to feel that they were engaged with the context of their learning and that it was meaningful in some way” (Solomonides and Martin 2008: 18). As a response to these conditions, the Changing Relationships action-research project was run within a QUT School of Design studio unit in 2009 and 2010, based on the premise that engaged teaching can encourage emotionally engaged learning. The project inverted the structure of the traditional QUT studio unit, empowering both students and sessional staff with a sense of increased autonomy: literally changing the relationships within the studio learning environment.'

Study of new particle formation in subtropical urban environment in Brisbane, Australia

Atmospheric ultrafine particles play an important role in affecting human health, altering climate and degrading visibility. Numerous studies have been conducted to better understand the formation process of these particles, including field measurements, laboratory chamber studies and mathematical modeling approaches. Field studies on new particle formation found that formation processes were significantly affected by atmospheric conditions, such as the availability of particle precursors and meteorological conditions. However, those studies were mainly carried out in rural areas of the northern hemisphere and information on new particle formation in urban areas, especially those in subtropical regions, is limited. In general, subtropical regions display a higher level of solar radiation, along with stronger photochemical reactivity, than those regions investigated in previous studies. However, based on the results of these studies, the mechanisms involved in the new particle formation process remain unclear, particularly in the Southern Hemisphere. Therefore, in order to fill this gap in knowledge, a new particle formation study was conducted in a subtropical urban area in the Southern Hemisphere during 2009, which measured particle size distribution in different locations in Brisbane, Australia. Characterisation of nucleation events was conducted at the campus building of the Queensland University of Technology (QUT), located in an urban area of Brisbane. Overall, the annual average number concentrations of ultrafine, Aitken and nucleation mode particles were found to be 9.3 x 103, 3.7 x 103 and 5.6 x 103 cm-3, respectively. This was comparable to levels measured in urban areas of northern Europe, but lower than those from polluted urban areas such as the Yangtze River Delta, China and Huelva and Santa Cruz de Tenerife, Spain. Average particle number concentration (PNC) in the Brisbane region did not show significant seasonal variation, however a relatively large variation was observed during the warmer season. Diurnal variation of Aitken and nucleation mode particles displayed different patterns, which suggested that direct vehicle exhaust emissions were a major contributor of Aitken mode particles, while nucleation mode particles originated from vehicle exhaust emissions in the morning and photochemical production at around noon. A total of 65 nucleation events were observed during 2009, in which 40 events were classified as nucleation growth events and the remainder were nucleation burst events. An interesting observation in this study was that all nucleation growth events were associated with vehicle exhaust emission plumes, while the nucleation burst events were associated with industrial emission plumes from an industrial area. The average particle growth rate for nucleation events was found to be 4.6 nm hr-1 (ranging from 1.79-7.78 nm hr-1), which is comparable to other urban studies conducted in the United States, while monthly particle growth rates were found to be positively related to monthly solar radiation (r = 0.76, p <0.05). The particle growth rate values reported in this work are the first of their kind to be reported for the subtropical urban area of Australia. Furthermore, the influence of nucleation events on PNC within the urban airshed was also investigated. PNC was simultaneously measured at urban (QUT), roadside (Woolloongabba) and semi-urban (Rocklea) sites in Brisbane during 2009. Total PNC at these sites was found to be significantly affected by regional nucleation events. The relative fractions of PNC to total daily PNC observed at QUT, Woolloongabba and Rocklea were found to be 12%, 9% and 14%, respectively, during regional nucleation events. These values were higher than those observed as a result of vehicle exhaust emissions during weekday mornings, which ranged from 5.1-5.5% at QUT and Woolloongabba. In addition, PNC in the semi-urban area of Rocklea increased by a factor of 15.4 when it was upwind from urban pollution sources under the influence of nucleation burst events. Finally, we investigated the influence of sulfuric acid on new particle formation in the study region. A H2SO4 proxy was calculated by using [SO2], solar radiation and particle condensation sink data to represent the new particle production strength for the urban, roadside and semi-urban areas of Brisbane during the period June-July of 2009. The temporal variations of the H2SO4 proxies and the nucleation mode particle concentration were found to be in phase during nucleation events in the urban and roadside areas. In contrast, the peak of proxy concentration occurred 1-2 hr prior to the observed peak in nucleation mode particle concentration at the downwind semi-urban area of Brisbane. A moderate to strong linear relationship was found between the proxy and the freshly formed particles, with r2 values of 0.26-0.77 during the nucleation events. In addition, the log[H2SO4 proxy] required to produce new particles was found to be ~1.0 ppb Wm-2 s and below 0.5 ppb Wm-2 s for the urban and semi-urban areas, respectively. The particle growth rates were similar during nucleation events at the three study locations, with an average value of 2.7 ± 0.5 nm hr-1. This result suggested that a similar nucleation mechanism dominated in the study region, which was strongly related to sulphuric acid concentration, however the relationship between the proxy and PNC was poor in the semi-urban area of Rocklea. This can be explained by the fact that the nucleation process was initiated upwind of the site and the resultant particles were transported via the wind to Rocklea. This explanation is also supported by the higher geometric mean diameter value observed for particles during the nucleation event and the time lag relationship between the H2SO4 proxy and PNC observed at Rocklea. In summary, particle size distribution was continuously measured in a subtropical urban area of southern hemisphere during 2009, the findings from which formed the first particle size distribution dataset in the study region. The characteristics of nucleation events in the Brisbane region were quantified and the properties of the nucleation growth and burst events are discussed in detail using a case studies approach. To further investigate the influence of nucleation events on PNC in the study region, PNC was simultaneously measured at three locations to examine the spatial variation of PNC during the regional nucleation events. In addition, the impact of upwind urban pollution on the downwind semi-urban area was quantified during these nucleation events. Sulphuric acid was found to be an important factor influencing new particle formation in the urban and roadside areas of the study region, however, a direct relationship with nucleation events at the semi-urban site was not observed. This study provided an overview of new particle formation in the Brisbane region, and its influence on PNC in the surrounding area. The findings of this work are the first of their kind for an urban area in the southern hemisphere.

A context-fusion framework for enhancing context-awareness on mobile application

Mobile devices and smartphones have become a significant communication channel for everyday life. The sensing capabilities of mobile devices are expanding rapidly, and sensors embedded in these devices are cheaper and more powerful than before. It is evident that mobile devices have become the most suitable candidates to sense contextual information without needing extra tools. However, current research shows only a limited number of sensors are being explored and investigated. As a result, it still needs to be clarified what forms of contextual information extracted from mo- bile sensors are useful. Therefore, this research investigates the context sensing using current mobile sensors, the study follows experimental methods and sensor data is evaluated and synthesised, in order to deduce the value of various sensors and combinations of sensor for the use in context-aware mobile applications. This study aims to develop a context fusion framework that will enhance the context-awareness on mobile applications, as well as exploring innovative techniques for context sensing on smartphone devices.

Antecedents of consumer brand loyalty in the Chilean wine industry

The wine industry has become fiercely competitive worldwide, and consumers are increasingly exposed to a wider range of wines in retail outlets. Therefore, wineries need to develop and build consumer loyalty toward their brands. The authors empirically test a model of wine brand loyalty in a Latin American context which considers wine brand trust, brand satisfaction, wine knowledge and wine experience as antecedents. Hypotheses are tested with structural equation modeling (SEM). Findings show that wine experience is positively related to brand trust and brand satisfaction. In addition, results show that consumer satisfaction with a wine brand is the strongest driver of brand loyalty.

Planning for success : repurposing, retooling and reprioritising with results

This paper presents an organisational learning system implemented across a three year period within a multi campus tertiary library. It proposes a three stage system, framed within a reflective evidence based practice process to foster professional engagement and lifelong learning of staff.

Turnover in entrepreneurial teams : are spousal teams different?

Entrepreneurial teams are increasingly prevalent. An important stage in new venture formation involves the recruitment and retention of team members, characterised by changes in the membership of the ET. ET turnover involves members joining or leaving the team, which could have positive or negative effects on the team and the firm. Spousal Entrepreneurial Teams (SET) are a frequently occurring, yet unique type of ET, with very distinct characteristics and dynamics. In an SET turnover is likely to be have different meanings and effects than in Other Entrepreneurial Teams. This research asks: What influences members joining and leaving entrepreneurial teams? And are SET different? Using data from 561 young firms over X years, we find significant differences between SET and NSET. Specifically, we find X.

Towards green universities : a decision support framework for green roof and living wall implementation

This research examined why university campus development has not fully embraced green technology despite common expectations. Semi-structured interviews and a Delphi Study explored universities’ organisational issues and delivery processes for projects with a sustainability focus. Critical organisational components and their internal relationships were studied, and critical factors for project success identified. A decision-making framework was developed to provide strategic directions for universities to optimise organisational environment and overcome barriers in order to better deliver sustainable projects on campuses.

Preventing public sector corruption : the relationship between parliamentary committees and corruption commissions

Parliamentary committees fulfil several important functions within the Parliament, with one of these being the oversight of various agencies including those that are designed to reduce corruption within the police service and other public sector agencies. The cross-party nature of committees combined with the protections of Parliament make them powerful agencies. Prenzler & Faulkner (2010) suggest that the ideal system for an agency that has oversight of a public sector integrity commission should include monitoring by a parliamentary committee, with an inspector attached to the committee. This occurs in Queensland, New South Wales and Western Australia. There has been very little research conducted on the role of parliamentary committees with oversight responsibilities for public sector integrity agencies. This paper will address this gap by examining the relationship between a parliamentary committee, a parliamentary inspector and a corruption commission. Queensland’s Parliamentary Crime and Misconduct Committee (PCMC/the Committee) and the Parliamentary Crime and Misconduct Commissioner (the Commissioner) provide oversight of the Crime and Misconduct Commission (CMC). By focussing on the PCMC and the Commissioner, the paper will examine the legislative basis for the Committee and Commissioner and their respective roles in providing oversight of the CMC. One key method by which the PCMC provides oversight of the CMC is to conduct and publish a review of the CMC every three years. Additionally, the paper will identify some of the similarities and differences between the PCMC and other committees that operate within the Queensland Parliament. By doing so, the paper will provide insights into the relationships that exist between corruption commissions, parliamentary committees and parliamentary inspectors and demonstrate the important role of the parliamentary committee in preventing instances of public sector corruption.

Making the implicit explicit : successful student skills for commencing cohorts

Making institutional expectations explicit using clear and common language engages commencing students and promotes help-seeking behaviour. When first year students enter university they cross the threshold into an unfamiliar environment (Devlin, Kift, Nelson, Smith & McKay, 2012). Universities endeavour to provide appropriate learning support services and resources; however research suggests that there is limited up take of these services, particularly in high risk students (Nelson-Field & Goodman, 2005). The Successful Student Skills Checklist is a tool which will be trialled during the 2013 Orientation period at the QUT Caboolture campus. The new tool is a response to the university’s commitment to provide “an environment where [students] are supported to take responsibility for their own learning, and to embrace an active role in succeeding to their full potential” (QUT, 2012, 6.2.1). This paper will outline the design of the support tool implemented during Orientation, as well as discuss the anticipated outcomes of the trial.

Let the journey begin : cultivating student identity and a sense of belonging through a formal academic welcome

Queensland University of Technology [QUT] Caboolture campus is a satellite campus co-located with Brisbane North Institute of TAFE. Building a sense of belonging on-campus continues to be challenging, with anecdotal evidence suggesting that QUT Caboolture students feel like second-class students, isolated from the prestige and excitement of the city campuses. A student identity and fostering a sense of belonging are fundamental to on-campus engagement and have been linked to retention (Field & Morgan-Klein, 2010). A formal welcome ceremony, including an academic procession in full regalia, was a new inclusion for QUT Caboolture’s 2013 Orientation Day. The ritual was intended to be a temporal mark for students to recognise their personal transition and emerging identity as a university student. Cultural capital is one ingredient in a complex mix of interactions and relationships to build a sense of identity. (Ecclestone, Biesta & Hughes, 2010). Fostering a sense of belonging and a connection to the campus and its staff was also anticipated. Students responded positively to the event, reporting feelings of excitement, inspiration and being welcomed into the university culture. The ceremony marked the beginning of the students’ journey together as QUT Caboolture students.

Urban transit quality of service : user perception and behaviour

Despite its potential multiple contributions to sustainable policy objectives, urban transit is generally not widely used by the public in terms of its market share compared to that of automobiles, particularly in affluent societies with low-density urban forms like Australia. Transit service providers need to attract more people to transit by improving transit quality of service. The key to cost-effective transit service improvements lies in accurate evaluation of policy proposals by taking into account their impacts on transit users. If transit providers knew what is more or less important to their customers, they could focus their efforts on optimising customer-oriented service. Policy interventions could also be specified to influence transit users’ travel decisions, with targets of customer satisfaction and broader community welfare. This significance motivates the research into the relationship between urban transit quality of service and its user perception as well as behaviour. This research focused on two dimensions of transit user’s travel behaviour: route choice and access arrival time choice. The study area chosen was a busy urban transit corridor linking Brisbane central business district (CBD) and the St. Lucia campus of The University of Queensland (UQ). This multi-system corridor provided a ‘natural experiment’ for transit users between the CBD and UQ, as they can choose between busway 109 (with grade-separate exclusive right-of-way), ordinary on-street bus 412, and linear fast ferry CityCat on the Brisbane River. The population of interest was set as the attendees to UQ, who travelled from the CBD or from a suburb via the CBD. Two waves of internet-based self-completion questionnaire surveys were conducted to collect data on sampled passengers’ perception of transit service quality and behaviour of using public transit in the study area. The first wave survey is to collect behaviour and attitude data on respondents’ daily transit usage and their direct rating of importance on factors of route-level transit quality of service. A series of statistical analyses is conducted to examine the relationships between transit users’ travel and personal characteristics and their transit usage characteristics. A factor-cluster segmentation procedure is applied to respodents’ importance ratings on service quality variables regarding transit route preference to explore users’ various perspectives to transit quality of service. Based on the perceptions of service quality collected from the second wave survey, a series of quality criteria of the transit routes under study was quantitatively measured, particularly, the travel time reliability in terms of schedule adherence. It was proved that mixed traffic conditions and peak-period effects can affect transit service reliability. Multinomial logit models of transit user’s route choice were estimated using route-level service quality perceptions collected in the second wave survey. Relative importance of service quality factors were derived from choice model’s significant parameter estimates, such as access and egress times, seat availability, and busway system. Interpretations of the parameter estimates were conducted, particularly the equivalent in-vehicle time of access and egress times, and busway in-vehicle time. Market segmentation by trip origin was applied to investigate the difference in magnitude between the parameter estimates of access and egress times. The significant costs of transfer in transit trips were highlighted. These importance ratios were applied back to quality perceptions collected as RP data to compare the satisfaction levels between the service attributes and to generate an action relevance matrix to prioritise attributes for quality improvement. An empirical study on the relationship between average passenger waiting time and transit service characteristics was performed using the service quality perceived. Passenger arrivals for services with long headways (over 15 minutes) were found to be obviously coordinated with scheduled departure times of transit vehicles in order to reduce waiting time. This drove further investigations and modelling innovations in passenger’ access arrival time choice and its relationships with transit service characteristics and average passenger waiting time. Specifically, original contributions were made in formulation of expected waiting time, analysis of the risk-aversion attitude to missing desired service run in the passengers’ access time arrivals’ choice, and extensions of the utility function specification for modelling passenger access arrival distribution, by using complicated expected utility forms and non-linear probability weighting to explicitly accommodate the risk of missing an intended service and passenger’s risk-aversion attitude. Discussions on this research’s contributions to knowledge, its limitations, and recommendations for future research are provided at the concluding section of this thesis.
