What's in a name : using a cue diagnosticity framework to understand consumer product search behaviour

Drawing from the cue diagnosticity framework, this study investigates consumer preference for gathering information about different product attributes. We predict that more specific attributes are more diagnostic and hence will be of greater value to a consumer who is in the process of undertaking a product selection. We test this hypothesis in an online product selection task where respondents can access four different product attributes: brand name, store name, price and warranty. We find that respondents choose to first obtain, almost equally, either brand or price information. We also find part confirmation for the hypothesis that an attribute is more likely to be chosen if it is perceived as having a greater variability in the market.

How should we measure indigenous entrepreneurship? A search for explanatory variables

In Canada and elsewhere around the world Indigenous Peoples are struggling to rebuild their ‘nations’ and improve the socioeconomic circumstances of their people. We are embarking on a program of research in an effort to understand this phenomenon and to inform the process. In this paper we (i) explore the approach to development being adopted by Indigenous people in Canada; (ii) conduct a preliminary literature review; (iii) identify input indicators of entrepreneurship and business development capacity, process measures of development activity and an output indicator of development effectiveness and (v) identify the information available from secondary sources relating to these indicators and the gaps in information that will have to be filled by primary research.

In search of a name for lesbians who mother their non-biological children

We are interested in how language has been used in the literature to describe and define the role and relationship of non-birth lesbian mothers to their children. Although previous researchers and clinicians have presented strong cases for a variety of descriptions, there is little agreement about what language best reflects and, indeed, legitimizes this relationship. We have previously argued that “the search for a definitive term is unlikely to bear fruit” (Brown & Perlesz, 2007), and, in this article, we revisit the variety of labels used and explore the implications of this language. Language is not only determined by social and individual understandings of mothering and parenting, but is also influenced by pathways to lesbian parenting and negotiated roles and relationships within families.  Language has the power not only to acknowledge and affirm but also to negate and render invisible the position and distinctive contribution of lesbian mothers who have not given birth to their children.

Spatial and temporal disparities in aurally aided visual search

Research over the last decade has shown that auditorily cuing the location of visual targets reduces the time taken to locate and identify targets for both free-field and virtually presented sounds. The first study conducted for this thesis confirmed these findings over an extensive region of free-field space. However, the number of sound locations that are measured and stored in the data library of most 3-D audio spatial systems is limited, so that there is often a discrepancy in position between the cued and physical location of the target. Sampling limitations in the systems also produce temporal delays in which the stored data can be conveyed to operators. To investigate the effects of spatial and temporal disparities in audio cuing of visual search, and to provide evidence to alleviate concerns that psychological research lags behind the capabilities to design and implement synthetic interfaces, experiments were conducted to examine (a) the magnitude of spatial separation, and (b) the duration of temporal delay that intervened between auditory spatial cues and visual targets to alter response times to locate targets and discriminate their shape, relative to when the stimuli were spatially aligned, and temporally synchronised, respectively. Participants listened to free-field sound localisation cues that were presented with a single, highly visible target that could appear anywhere across 360° of azimuthal space on the vertical mid-line (spatial separation), or extended to 45° above and below the vertical mid-line (temporal delay). A vertical or horizontal spatial separation of 40° between the stimuli significantly increased response times, while separations of 30° or less did not reach significance. Response times were slowed at most target locations when auditory cues occurred 770 msecs prior to the appearance of targets, but not with similar durations of temporal delay (i.e., 440 msecs or less). When sounds followed the appearance of targets, the stimulus onset asynchrony that affected response times was dependent on target location, and ranged from 440 msecs at higher elevations and rearward of participants, to 1,100 msecs on the vertical mid-line. If targets appeared in the frontal field of view, no delay of acoustical stimulation affected performance. Finally, when conditions of spatial separation and temporal delay were combined, visual search times were degraded with a shorter stimulus onset asynchrony than when only the temporal relationship between the stimuli was varied, but responses to spatial separation were unaffected. The implications of the results for the development of synthetic audio spatial systems to aid visual search tasks was discussed.

The holy grail : the search for the optimal gaar

The sustainability of a taxation system relies in part in reducing effective tax avoidance as far as is possible. Tax avoidance impacts on the economy both because it results in revenue loss and because it diverts people into devising, marketing and implementing avoidance arrangements, rather than engaging in economically productive activities. Revenue losses in turn weaken the government's ability to formulate and implement fiscal policies. Moreover, the very integrity of a tax system, necessary for its long-term sustainability, is attacked by tax avoidance. The goal of equity is undermined by tax avoidance as typically these schemes are accessed by the wealthy. Thus, tax avoidance results in an unfair shift in the tax burden to the less wealthy in society. As one commentator recently noted, combating 'tax avoidance ... will serve to lessen the overall burden on all taxpayers'. Further, legislative responses to tax avoidance increase the complexity of a taxation scheme. Tax avoidance schemes also undermine the neutrality of a taxation system by distorting trade and investment decisions. Thus, tax avoidance attacks every aspect of a fair, and hence, sustainable, taxation system.

In search of the tendon holy grail : predictable clinical outcomes

What is your first reaction when you find out your next patient has a long-term tendinopathy? I suspect you want to hide or get an urgent phone call that drags you away from the practice. You know that the person will have tried multiple interventions, probably had several injections, read all the literature about treatments for tendinopathy on the internet and want an immediate and lifelong cure. You also know that your assessment will take well into your next patient’s time allotment and even then it will remain difficult to prioritise treatments and to explain the rationale behind your plan to the patient. Even as a tendon researcher and part-time clinician whose practice consists solely of tendinopathy patients, my reactions to chronic tendinopathy patients are similar.

An evaluation of Sea Search as a citizen science programme in Marine Protected Areas

Citizen science involves collaboration between multi-sector agencies and the public to address a natural resource management issue. The Sea Search citizen science programme involves community groups in monitoring and collecting subtidal rocky reef and intertidal rocky shore data in Victorian Marine Protected Areas (MPAs), Australia. In this study we compared volunteer and scientifically collected data and the volunteer motivation for participation in the Sea Search programme. Intertidal rocky shore volunteer-collected data was found to be typically comparable to data collected by scientists for species richness and diversity measures. For subtidal monitoring there was also no significant difference for species richness recorded by scientists and volunteers. However, low statistical power suggest only large changes could be detected due to reduced data replication. Generally volunteers recorded lower species diversity for biological groups compared to scientists, albeit not significant. Species abundance measures for algae species were significantly different between volunteers and scientists. These results suggest difficulty in identification and abundance measurements by volunteers and the need for additional training requirements necessary for surveying algae assemblages. The subtidal monitoring results also highlight the difficulties of collecting data in exposed rocky reef habitats with weather conditions and volunteer diver availability constraining sampling effort. The prime motivation for volunteer participation in Sea Search was to assist with scientific research followed closely by wanting to work close to nature. This study revealed two important themes for volunteer engagement in Sea Search: 1) volunteer training and participation and, 2) usability of volunteer collected data for MPA managers. Volunteer-collected data through the Sea Search citizen science programme has the potential to provide useable data to assist in informed management practices of Victoria’s MPAs, but requires the support and commitment from all partners involved.

Black and white : in search of an ‘apt’ response to Indigenous writing

‘The good editor,’ suggests Thomas McCormack in his Fiction Editor, the Novel and the Novelist, ‘reads, and … responds aptly’ to the writer’s work, ‘where “aptly” means “as the ideal appropriate reader would”.’ McCormack develops an argument that encompasses the dual ideas of sensibility and craft as essential characteristics of the fiction editor. But at an historical juncture that has seen increasing interest in the publication of Indigenous writing, and when Indigenous writers themselves may envisage a multiplicity of readers (writing, for instance, for family and community, and to educate a wider white audience), who is the ‘ideal appropriate reader’ for the literary works of the current generation of Australian Indigenous writers? And what should the work of this ‘good editor’ be when engaging with the text of an Indigenous writer? This paper examines such questions using the work of Margaret McDonell and Jennifer Jones, among others, to explore ways in which non-Indigenous editors may apply aspects of McCormack’s ‘apt response’ to the editing of Indigenous texts.

A trilogy on discontinuous innovation. Part I : search

In this article we discuss the concept of Discontinuous Innovation (DI) and how it differs from incremental (or steady-state) innovation. We propose a model to conceptualise the different aspects of DI and discuss the complex nature of the DI process through an investigation of previous literature, and propose a sequence of articles roughly following the key components as described in the conceptual model, beginning with aspects of ‘search’. We then describe an on-going multi-national action research program established to investigate DI through the development of learning networks of firms in several European nations and Australia. The research progress to date is outlined and initial results of analysis on both quantitative and qualitative data collected thus far is used to explore how companies go about searching for clues or ideas about potential discontinuous innovations, which may either create competitive advantage for, or threaten the survival of the business. Key outcomes of the research to date include the identification of the most common search strategies within the participating companies and some descriptive analysis on just how these strategies are implemented in targeted firms. Finally we describe the proposed future research program and the two papers to follow completing the planned three part series on Discontinuous Innovation.

Asset-selling problem with an uncertain deadline, quitting offer, and search skipping option

This paper presents a discrete-time sequential stochastic asset-selling problem with an infinite planning horizon, where the process of selling the asset may reach a deadline at any point in time with a probability. It is assumed that a quitting offer is available at every point in time and search skipping is permitted. Thus, decisions must be made as to whether or not to accept the quitting offer, to accept an appearing buyer’s offer, and to conduct a search for a buyer. The main purpose of this paper is to clarify the properties of the optimal decision rules in relation to the model’s parameters.
