Attending to risk in sequential sampling plans

Researchers typically tackle questions by constructing powerful, highlyreplicated sampling protocols or experimental designs. Such approaches often demand large samples sizes and are usually only conducted on a once-off basis. In contrast, many industries need to continually monitor phenomena such as equipment reliability, water quality, or the abundance of a pest. In such instances, costs and time inherent in sampling preclude the use of highlyintensive methods. Ideally, one wants to collect the absolute minimum number of samples needed to make an appropriate decision. Sequential sampling, wherein the sample size is a function of the results of the sampling process itself, offers a practicable solution. But smaller sample sizes equate to less knowledge about the population, and thus an increased risk of making an incorrect management decision. There are various statistical techniques to account for and measure risk in sequential sampling plans. We illustrate these methods and assess them using examples relating to the management of arthropod pests in commercial crops, but they can be applied to any situation where sequential sampling is used.

Behavioral versus demographic predictors of early adoption : a critical analysis and comparative test

Predicting which consumers will be amongst the first to adopt an innovative product is a difficult task but is valuable in allowing effective and efficient use of marketing resources. This paper examines the accuracy of predictions made about likely first adopters based on the most widely accepted theory and compares them to predictions made by examining the relevant past behavior of consumers. A survey of over 1000 consumers examined adoption of an innovative technology: compact fluorescent lightglobes. The results show that variables which were derived from a utility and awareness perspective were a more accurate and managerially useful predictor than the demographic variables derived from the widely accepted theory based on the work of Rogers. It is suggested that these alternative variables could be utilized more readily by marketing managers in many circumstances.

Evaluation of fixed sample-size plans for Plutella xylostella (Lepidoptera: Plutellidae) on broccoli crops in Australia

Fixed sample-size plans for monitoring Plutella xylostella (L.) (Lepidoptera: Plutellidae) on broccoli and other Brassica vegetable crops are popular in Australia for their simplicity and ease of application. But the sample sizes used are often small, ≈10–25 plants per crop, and it may be that they fail to provide sufficient information upon which to base pest control decisions. We tested the performance of seven fixed sample-size plans (10, 15, 20, 30, 35, 40, and 45 plants) by resampling a large data set on P. xylostella in commercial broccoli crops. For each sample size, enumerative and presence-absence plans were assessed. The precision of the plans was assessed in terms of the ratio of the standard error to the mean; and at least 45 and 35 samples were necessary for the enumerative and presence-absence plans, respectively, to attain the generally accepted benchmark of ≤0.3. Sample sizes of 10–20 were highly imprecise. We also assessed the consequences of classifications based on action thresholds (ATs) of 0.2 and 0.8 larvae per plant for the enumerative case, and 0.15 and 0.45 proportion of plants of infested for the presence-absence case. Operating characteristic curves and investigations of the frequency of correct decisions suggest improvements in the performance of plans with increased sample size. In both the enumerative and presence-absence cases, the proportion of incorrect decisions was much higher for the lower of the two ATs assessed, and type II errors (i.e., failure to suggest pest control upon the AT is exceeded) generally accounted for the majority of this error. Type II errors are the most significant from a producer’s standpoint. Further consideration is necessary to determine what is an acceptable type II error rate.

Experiences of regional and rural people with cancer being treated with radiotherapy in a metropolitan centre

This paper explores the issues related to rural people with cancer whose choice of radiotherapy treatment necessitated travel and accommodation in a metropolitan centre. Semi-structured interviews with 46 participants, from the Toowoomba and Darling Downs region of Queensland, Australia, were conducted and the data thematically analysed. The specific themes identified were: being away from loved ones, maintaining responsibilities whilst undergoing treatment, emotional stress, burden on significant others, choice about radiotherapy as a treatment, travel and accommodation, and financial burden. This study supports the need for a radiotherapy centre in the location of Toowoomba as a way of providing some equity and access to such treatment for the rural people of Queensland.

One to one eMarketing strategy alignment: five internet case studies

Despite widespread adoption of new online business models and the rise of online or eMarketing using the Internet (Net) and its current graphical face the World Wide Web (Web), there remains a need for empirical research into specific aspects of eMarketing strategy beyond clickthrough analysis, Web audience analysis and scrutiny of Websites properties to mention the most widely examined elements. This paper discusses Peppers and Rogers (1999) OnetoOne strategy matrix and synthesises their approach with a series of personal interviews with business managers, drawn from a broader empirical study. It does so in an endeavour to improve outcomes from eMarketing strategy and the use of individual Net technologies. The aim is to aid both business practitioner and academician alike in further improving the effectiveness and efficiency gained from using converging technologies in eBusiness.

Transacting with citizens: Australian government policy, strategy and implementation of online tax lodgement

Many governments have shown leadership in encouraging their citizenry to conduct transactions on-line. The policies that underpin these initiatives refer to a blend of civic benefits and efficiency goals. They combine the rhetoric of customer service with social shaping through ‘government as model user’ and procedures that require online activities. Many initiatives are described as ‘electronic service delivery’, terms that indicate an intention to provide much more than an additional channel for government interaction with citizens. Australia, as an innovator in eGovernment is a good example of this approach and its national government has specified policy goals for its online strategy. In this paper we examine the case of one Australian online delivery initiative, electronic tax lodgement (e-tax) and consider how well that initiative has met the policy goals of the government. Combining insights from Rogers’ Diffusion of Innovation theory and political analysis, we outline potential difficulties that governments face in implementing ESD initiatives. Our conclusion from this case study is that the provision of good technology is only a small part of the ESD challenge. It shows how success of an ESD implementation may yield contradictory outcomes in terms of overall eGovernment strategies. This case highlights the need for long-term
implementation plans and integration of initiatives with broader government strategy.

Inclusion and accountability: communications research with consumers with disabilities

Over the past two decades there has been an increasing focus on doing research with and for consumers rather than on consumers. Research that is collaborative and inclusive has been called for by people with disabilities. People with disabilities are a group of telecommunications consumers who are disadvantaged because of social barriers and access issues with equipment, services and information. In this paper, the benefits and challenges of collaborative (e.g. participatory, participatory action, emancipatory) research with these consumers and the processes that can facilitate inclusive and accountable research outcomes are addressed. Throughout the paper, four questions will be explored: Who determines which research issues are explored and the methods that are used? What is the level of consumer involvement in the research process? How can academics and government ensure that consumer-focused research is inclusive and participatory? How, and to whom, should research results be made available?

In the first part of the paper, the perspectives on consumer research by people with disabilities are presented. Respect for and appreciation of consumers' views underpins the philosophical stance needed by researchers and funding bodies before serious engagement in empowering, person-centred research can be successful.

In the second part of the paper, there is a focus on defining the features of collaborative research approaches. Participatory research, participatory action research, and emancipatory research are variations that incorporate differing levels of consumer involvement. Each of these, however, embrace shifts in philosophy and methods away from more traditional 'scientific' research. Such changes result in a greater sense of inclusion and project ownership by consumers.

The third part of the paper addresses some of the issues associated with collaborative research for consumers with disabilities, for academic researchers, and for government funding bodies. Differing understandings of the social nature of disablement influence attitudes toward consumer involvement and are demonstrated in the choice of research questions, project aims, and the methodologies used. Differing agendas are reflected in reactions to the traditional project requirements and processes of government, the preferred research methodologies of researchers, and the perceived accountability of researchers or government for the dissemination and sharing of research results. The challenges to successful engagement with consumers in collaborative research have been identified in the literature and a number of strategies recommended (Barnes, 2003; Clear, 1999; Mercer, 2002; Oliver, 1992, 1997; Zarb, 1997). Application of inclusive strategies by researchers and funding bodies is essential for positive change and inclusive, empowering outcomes.

The paper concludes with a case study of a DCITA-funded research project. The project is evaluated using participatory/emancipatory research criteria modified from Zarb (1992) and addresses consumer, researcher, and funding body participation. The four questions used in the discussion of the paper are applied to this particular project. In addition, the benefits and learnings from the project will be compared with the outcomes desired by consumers who espouse collaborative research approaches.

Adopting web-based learning and teaching: a case study in higher education

Most universities worldwide are becoming distance education providers through adopting web-based learning and teaching via the introduction of learning management systems that enable them to open their courses to both on- and off-campus students. Whether this is an effective introduction depends on factors that enable and impede the adoption of such systems and their related pedagogical strategies. This study examines such factors related to adopting a learning management system in a large multicampus urban Australian university. The research method used case study approaches and purposively selected the sample consisting of innovative teaching academics from across the university, who used web-based approaches to teach both on- and off-campus learners. The data were analyzed using a combination of Rogers' theory of diffusion of innovations and actor-network theory and revealed a series of enabling and impeding factors faced by pioneering technology-adopter teaching academics, some of which are technology related while others are policy related and common to large multicampus institutions. The study found that safe adoption environments recognizing career priorities of academics are a result of the continuous negotiation between the evolving institution and its innovative and creative staff. The article concludes with a series of conditions that would form a safe, enabling, and encouraging environment for technology-adopter teaching academics in a large multicampus higher education setting.

Performance of a 120 m2 solar air heater for a commercial building in Victoria

The operation of two 60 m² solar air heaters serving a large studio teaching space has been monitored for a twelve month period. The solar contribution of the heaters was found to be less than 5%, and in some instances the heaters actually contributed to the space heating load. A validated mathematical model of the studio and it’s heating, ventilation and air conditioning system was used to investigate performance improvement strategies. It was found a different control strategy and recommissioned control sensors would substantially improve the solar air heater performance.

Species-specific characteristics and individual variation of the bark call produced by male Australian fur seals (Arctocephalus pusillus doriferus)

Australian fur seals Arctocephalus pusillus doriferus are colonial breeding animals forming dense social groups during the breeding season. During this time, males establish and defend territories through physical conflicts, stereotyped posturing and vocalisations. While vocalisations are suggested to play an important role in male recognition systems, it has received little attention. Recordings of nine adult male Australian fur seals were made during the 2000 and 2001 breeding seasons at Kanowna Island (39° 10’S, 146° 18' E), Bass Strait, Australia. The in-air bark vocalisations of territory-holding males were used to characterise the Bark Call and to determine whether males produce individually distinct calls, which could be used as a basis for vocal recognition. Seventeen frequency and temporal variables were measured from a total of 162 barks from nine individual males. The Bark Series was more reliably classified (83%) to the correct caller compared to the Bark Unit. This was assigned with less certainty (68%), although the classification was still relatively high. Findings from this study indicate that there is sufficient stereotypy within individual calls, and sufficient variation between them, to enable vocal recognition in male Australian fur seals.

To choose or not to choose: exploring Australians` views about internet banking

This paper explores Australian domestic customers' choices with regard to Internet banking, examining why it is taken up by some Australians and not others. The constructivist conceptual framework and the grounded nature of the method enabled in-depth exploration of key issues not undertaken before by the mainly positivist studies. The purposeful sample of 32 participants was selected to represent the major categories of people relevant to the research. Everett Rogers' famous analysis of 'diffusion of innovations' was one theoretical framework used to illuminate the findings; the other was digital divide factors in relation to banking choices. The findings include 1) that the major motivation for people to adopt Internet banking is convenience, closely linked to time savings and ease of accessibility, as well as confidence and skill in Internet use; and 2) that, at the time of the study, digital divide factors were playing an important part in banking choices.
