Changes in Inequalities of Access to Dental Care in Australia 1977–2005

Information on dental visits, income and demographic variables were drawn from the Australian National Health Survey between 1977 and 2005. Income‐related inequality in access to dental care was calculated using the generalised concentration index (G) and decomposition methods were employed to examine associations with socio‐demographic and policy‐amenable factors. Statistically significant increases in inequality in dental care use were found after 1995. From 0.026 in 1995, G increased to 0.045 in 2005. The associations between increases in inequality and changes in the uptake of private health insurance suggest a contributory role of the introduction of the Commonwealth government's 30 per cent rebate for private health insurance.     

Assessing High-Risk Scenarios by Full-Range Tail Dependence Copulas

Copulas with a full-range tail dependence property can cover the widest range of positive dependence in the tail, so that a regression model can be built accounting for dynamic tail dependence patterns between variables. We propose a model that incorporates both regression on each marginal of bivariate response variables and regression on the dependence parameter for the response variables. An ACIG copula that possesses the full-range tail dependence property is implemented in the regression analysis. Comparisons between regression analysis based on ACIG and Gumbel copulas are conducted, showing that the ACIG copula is generally better than the Gumbel copula when there is intermediate upper tail dependence. A simulation study is conducted to illustrate that dynamic tail dependence structures between loss and ALAE can be captured by using the one-parameter ACIG copula. Finally, we apply the ACIG and Gumbel regression models for a dataset from the U.S. Medical Expenditure Panel Survey. The empirical analysis suggests that the regression model with the ACIG copula improves the assessment of high-risk scenarios, especially for aggregated dependent risks.     

The Effects of Background Music on Consumer Responses in a High-end Supermarket

Abstract

This study examines the effects of in-store background music valence (liking) and music fit with the overall store image on consumer evaluative and behavioural responses in the context of a high-end supermarket chain. Based on the previous body of work, a conceptual model is developed to examine music valence on customer appraisal of store offering and personnel, and on the length of shopping time and the value of purchase. The influence of the perceived music fit with the overall store image on shopping time is also assessed in the model. The hypothesized relationships are examined via covariance analysis using store-intercept consumer data. Implications of the structural analyses results for management of retail store brands and for future research on music as an element of store atmospherics are discussed.     

The potential value of rapid,cloud-enabled onsite testing for the diagnosis of rheumatoid arthritis in the United States

Abstract

Aims: Improvements in information technology have granted the recent development of rapid, cloud-enabled, onsite laboratory testing for rheumatoid arthritis (RA). This study aims to quantify the value to payers of such technologies.

Materials and methods: To calculate the value of rapid, cloud-enabled, onsite laboratory testing to diagnose RA relative to traditional, centralized laboratory testing, an Excel-based decision tree model was created that simulated potential cost-savings to payers who cover routine evaluations of RA patients in the US. First, a conceptual framework was created to identify the value components of rapid, cloud-enabled onsite testing. Second, value associated with patient time savings, savings on visit fees, change in treatment costs, and QALY improvements was measured, leveraging existing literature and information from an observational study. Lastly, these value components were combined to estimate the total incremental value accruing to payers per patient-year relative to centralized laboratory testing.

Results: Rapid, cloud-enabled, onsite testing is estimated to save one office and 1.81 laboratory visits during the evaluation period for the average patient. Results from an observational study found that rapid, cloud-enabled testing increased the likelihood of completing diagnostic orders from 84.5% to 97%, resulting in an increased probability of early treatment (3.5 percentage points) with disease-modifying anti-rheumatic drugs among patients eligible for treatment. The combined total value was $5,648 per evaluated patient-year. This value is primarily attributed to health benefits of early treatment ($5,048), fewer visit payments ($459), and patient time savings due to fewer office ($216) and laboratory visits ($255).

Limitations and conclusions: Data on the impact of rapid, cloud-enabled, onsite testing on patient health, care delivery, and clinical decision-making is scarce. More robust real-world data would confirm the validity of our model. Rapid, cloud-enabled, onsite testing has the potential to generate significant value to payers.     

Using vehicle monitoring technology and eco-driver training to reduce fuel use and emissions in tourism: a ski resort case study

Ground-based transport moves more tourists than any other form of transportation and contributes c. 32% of tourism's carbon dioxide (CO₂) emissions – yet remains a largely neglected area of emission/carbon management research. This study examines the value of vehicle monitoring technology (VMT) and eco-driver training as a means to improve fuel efficiency and reduce CO₂ emissions for a fleet of vehicles at the largest ski resort operation in Ontario, Canada. The VMT was installed in 14 fleet vehicles. After eco-driver training, the fleet reduced its average daily speed (?14%), hard decelerations (?55%), hard accelerations (?44%), and idling time (?2%), resulting in decreased fuel costs (?8%) and CO₂ emissions (?8%). The process requires very low capital expenditures, can pay for itself in as little as one year, and has safety paybacks. It also has valuable externalities: tourism businesses that instill sustainability awareness and values to their employees contribute to environmental prosperity generally, because eco-trained drivers also drive more efficiently in their everyday lives. This is the first known study to quantify the benefits of driver training and behavioral intervention within a tourism context, demonstrating the potential to enhance environmental sustainability while simultaneously reducing operating costs. Technicalities, issues, and future application possibilities are discussed.     

Does ECO certification deliver benefits? An empirical investigation of visitors’ perceptions of the importance of ECO certification's attributes and of operators’ performance

Certification is highlighted as a key sustainable tourism management tool. Yet, very little is known about visitors’ perceptions of such schemes. This is an important gap: the success of certification schemes depends on consumers’ confidence in the quality of products and services that the schemes endorse. This paper surveyed 610 visitors to the Wet Tropics World Heritage Area and surrounds in Queensland, Australia about (1) the perceived importance of various attributes of the ECO certification scheme; and (2) the perceived performance of operators based on those attributes. Data analysis identified aspects of ECO certification and of operator performance that may need improvement. It found that importance of attributes varied across products and visitor groups; at accommodations, most attributes were perceived to be important, Nature (as an aesthetic experience) and Marketing being more important than others, while at attractions and on tours, visitors were indifferent. Younger visitors rated Environment and Conservation more highly than their older counterparts and females rated Conservation more highly than males. Visitors – notably at accommodations – considered that ECO certified operators were performing “better” than non-ECO certified operators on many attributes. How these visitor perceptions translate into reality remains an important topic for future research.     

Adequacy versus equivalency: Financial data protection and the U.S.–EU divide

In 1995, the European Union passed Directive 95/46/EC, which set the legal framework for European Union citizens to own the rights to their personal data. However, American law bestows ownership to the holder of the data, not the individual, and officials feared the European Union initiative might disrupt data sharing among United States and European Union affiliates. Thus, they negotiated the 2000 Safe Harbor Agreement to allow companies to voluntarily submit to yearly certifications that fulfilled European Union demands, but kept U.S. businesses in control of their data; nevertheless, the Agreement does not include financial and banking services. Instead, the United States argued that the privacy protections within the Gramm-Leach-Bliley Act adequately fulfilled European Union guidelines. The European Union disagreed and financial data sharing has operated under a moratorium for the past decade. However, the 2008 financial crisis has governments and clients clamouring for more data transparency to determine risk in the financial system. These global efforts, the European Union's recent push to strengthen the Directive, and the Dodd-Frank Act have pushed data sharing to the policy forefront. This article asserts that transatlantic data sharing will ultimately have to accommodate the privacy cultures in both the United States and the European Union, but firms must be prepared to cope with demands on their data by establishing government relations offices, standardizing information systems, enhancing education for compliance officers, and improving business school curricula.     

Ethical Analyses of HRM: A Review and Research Agenda

The very idea of human resource management raises ethical considerations: What does it mean to us as humans for human beings to be managed as resources? Intriguingly, the field of ethics and HRM remains underdeveloped. Current approaches to HRM fail to place ethical considerations as their central warrant. This article, building on Greenwood (J Bus Ethics 36(3):261–279, 2002), argues for a deeper analysis of ethical issues in HRM, indeed for a differentiated ethical perspective of HRM that sets normative deliberations as its prime task. By identifying a distinct ethical approach to HRM that is unashamedly normative and socio-politically embedded, two objectives can be achieved. First, mainstream and critical approaches will be challenged to take ethical issues in HRM more seriously. Second, a dedicated forward-looking research agenda for the ethical analysis of HRM will be advanced.     

Customers’ everyday understanding of ‘value’ from a second-order cybernetic perspective

ABSTRACT

Value is in the centre of service and marketing. However, what does value mean to customers? The purpose of the paper is to contribute to an understanding of value from a customers’ perspective using a second-order cybernetics approach. We found that the word ‘value’ is recursively linked to 13 different ‘meanings’ indicating a variety of understandings of the term ‘value’. Furthermore, the findings support service-dominant logic where customers integrate their own resources (skills and knowledge) in the value co-creation process. Future research has to be aware of the different meanings, which are associated with value. Marketing managers need to understand, on the one hand, that value has a different meaning to their customer and on the other hand, what value means to their specific target groups.     

Entry and Exit Behavior in the Absence of Sunk Costs: Evidence from a Price Comparison Site

This paper explores entry and exit at a price comparison site (PCS) where the sunk costs of participation are effectively zero. We first use an unbalanced panel of 295 products on NexTag.com to estimate an error correction model of net entry. Although the results support our characterization of the PCS as a zero sunk cost market in which potential sellers behave as Kirznerian entrepreneurs in responding to opportunities, it is clear the net entry flow involves participants with widely differing behavior. This is investigated by examining exit and re-entry decisions at the seller level, which reveal that size and reputation determine individual responses to market opportunities.
