The cost of diabetes and obesity in Australia

Aims: To assess and compare the direct healthcare and non-healthcare costs and government subsidies by body weight and diabetes status.

Methods: The Australian Diabetes, Obesity and Lifestyle study collected health service utilization and health-related expenditure data at the 2011–2012 follow-up surveys. Costing data were available for 4,409 participants. Unit costs for 2016–2017 were used where available or were otherwise inflated to 2016–2017 dollars. Age- and sex-adjusted costs per person were estimated using generalized linear models.

Results: The annual total direct cost ranged from $1,998 per person with normal weight to $2,501 per person with obesity in participants without diabetes. For those with diabetes, total direct costs were $2,353 per person with normal weight, $3,263 per person with overweight, and $3,131 per person with obesity. Additional expenditure as government subsidies ranged from $5,649 per person with normal weight and no diabetes to $8,085 per person with overweight and diabetes. In general, direct costs and government subsidies were higher for overweight and obesity compared to normal weight, regardless of diabetes status, but were more noticeable in the diabetes sub-group. The annual total excess cost compared with normal weight people without diabetes was 26% for obesity alone and 46% for those with obesity and diabetes.

Limitations: Participants included in this study represented a healthier cohort than the Australian population. The relatively small sample of people with both obesity and diabetes prevented a more detailed analysis by obesity class.

Conclusion: Overweight and obesity are associated with increased costs, which are further increased in individuals who also have diabetes. Interventions to prevent overweight and obesity or reduce weight in people who are overweight or obese, and prevent diabetes, should reduce the financial burden.     

Consumer Regulation Strategies: Attenuating the Effect of Consumer References in a Voting Context

Consumption cues (e.g., brands, money, and advertisements) can have powerful effects on cognition, perception, and behavior, yet how people regulate responses to such cues is not well understood. This is surprising given that consumption cues are increasingly present in nontraditional consumer contexts, such as healthcare, education, and politics. This research develops a measure of two types of consumer regulation strategies, cue‐based and budget‐based (studies 1–4), and demonstrates that these strategies influence how people respond to consumption cues in a political context (study 5). Specifically, in a study involving the 2012 American Presidential Election, priming survey participants as consumers (versus citizens) influenced both voting intentions and self‐reported voting behavior, and the newly developed consumer regulation scale was instrumental in detecting this effect. These findings suggest there may be merit in the escalating debate and concern over referring to voters as consumers.     

Full versus quasi MLE for ARMA-GARCH models with infinitely divisible innovations

We compare the backtesting performance of ARMA-GARCH models with the most common types of infinitely divisible innovations, fit with both full maximum likelihood estimation (MLE) and quasi maximum likelihood estimation (QMLE). The innovation types considered are the Gaussian, Student’s t, α-stable, classical tempered stable (CTS), normal tempered stable (NTS) and generalized hyperbolic (GH) distributions. In calm periods of decreasing volatility, MLE and QMLE produce near identical performance in forecasting value-at-risk (VaR) and conditional value-at-risk (CVaR). In more volatile periods, QMLE can actually produce superior performance for CTS, NTS and α-stable innovations. While the t-ARMA-GARCH model has the fewest number of VaR violations, rejections by the Kupeic and Berkowitz tests suggest excessively large forecasted losses. The α-stable, CTS and NTS innovations compare favourably, with the latter two also allowing for option pricing under a single market model.     

Outcomes from use of an evidence-based practice guideline

The aim of evidence-based guidelines is primarily to improve patient outcomes without adding to the existing cost of care because both payers and policymakers want to identify health care costs that do not result in benefit to the patient. The purpose of the reported project was to generate a practice guideline for the treatment of uncomplicated acute cystitis in a female population, to determine the extent to which the guideline would be used by providers and to measure the cost and quality of outcomes from its use. A retrospective chart review was used to gather pre-guideline practice and cost data. Measurements included the type, frequency, and duration of antibiotic therapy and the use of urine cultures and both complications and routine followup visits. The implementation of an outpatient practice guideline resulted in a significant change in antibiotic prescribing and a trend toward a change in ordering cultures and clinic followup. There was also a significant decrease in treatment costs.     

Innovation Aesthetics: The Relationship between Category Cues,Categorization Certainty,and Newness Perceptions

Recent research notes a disconnect between what marketers deem new and innovative versus what consumers actually perceive. Many factors may contribute to this; however, the factor that has significant potential to first attract a consumer to a new product, visual aesthetic design, is investigated in this research. Findings from four studies indicate that if a consumer cannot affix a category label to a new product with certainty, as can happen with innovative aesthetics, a product's newness will be underappreciated and product evaluations will suffer. By utilizing a categorization framework and specifically accounting for the role of categorization certainty, insight into the effects of innovative visual aesthetics and why newness perceptions are inherently subjective, and therefore, potentially hazardous to new product adoption, is provided.     

Introduction to the Special Issue - The Brave New World: How shopping and consumption is evolving with technology

This special issue of the Canadian Journal of Administrative Sciences features four articles using various methodologies to explore the interplay of technology and consumption. Through an exploration of identity expression in virtual reality to the consumption of fashion media and culture to inspiring the use of wearables, we learn that although new technologies may change traditional consumption patterns, fundamental human needs persist. From this special issue, it is evident the so-called brave new world will require companies, and marketers especially, to not lose sight of the human when using and experimenting with technologies to streamline and enhance consumption and marketplace experiences.     

The numbing effect of mortality salience in consumer settings

Nationwide Insurance and Johnnie Walker Scotch aired advertisements that encouraged people to contemplate death. What are the immediate emotional and perceptual outcomes of such advertisements? With five studies, thinking about death was found to attenuate emotional reactions and perceptions, a novel finding in the literature. This attenuation was observed with neural and self‐report measures along with retrospective and prospective assessments of emotion and is an outcome not yet investigated in mortality salience research. Contemplating death dampened people's expectations of emotion in a future consumption experience and diminished the attractiveness of the experience. Similarly, contemplating death affected backward‐looking assessments of emotion, for example, when nostalgic memories are brought to mind. Importantly, this dampening effect of mortality salience was replicated with advertisements that portrayed death‐related concepts and attenuated emotional reactions to subsequent advertisements.     

Technical Efficiency in the Production of Economic Knowledge

This paper is an attempt to estimate technical efficiency in the production of economic knowledge. To that end, an educational production frontier was estimated via linear programming and an index of technical efficiency computed by forming the ratio, actual post TUCE/computed post TUCE. Professor teaching preferences and student learning preferences along with age and sex were used as regressors in an attempt to identify factors accounting for technical efficiency. Students were found to be very efficient in the production of knowledge.     

Modelling satisfaction with ATMs: A cross-country comparison

The aim of this paper is to extend the work of Goode and Moutinho by applying their model to a different country, namely Hungary, and then comparing the results. The hypothesised model links overall satisfaction to seven explanatory variables (namely expectations, perceived risk, confidence, recommendations to others, level of charges, frequency of use and full use of services). This paper is divided into four parts, the first of which looks at the UK and Hungarian banking systems. The second section describes the methodology and data collection used in this study. The third section analyses the empirical results derived from applying the model and the final section discusses the results and managerial implications of the results obtained from this study.     

What Motivates Software Crackers?

Software piracy is a serious problem in the software industry. Software authors and publishing companies lose revenue when pirated software rather than legally purchased software is used. Policy developers are forced to invest time and money into restricting software piracy. Much of the published research literature focuses on software piracy by end-users. However, end-users are only able to copy software once the copy protection has been removed by a ‘cracker’. This research aims to explore why, if copy protection is so difficult to remove, do crackers invest their skill and time in this activity instead of more lucrative and legal employment. This study develops a framework of neutralisation, justification and motivation and goes directly to the initial software crackers to determine what motivates their activities. The study first applies this framework in an anonymous online survey of crackers. The study then conducts cognitive interviews with eight crackers to explore and further validate the survey’s findings. The study finds the challenge of removing the copy protection from software as the strongest motivation for the actions of crackers. Desire for social participation, while found to be rewarding, was considered unnecessary for crackers to continue their actions. Higher social status was not a motivational factor but was a perceived by-product of cracking. The study also raises areas for future research.
