Wine prices and quality eatings: a meta-regression analysis

This article examines the empirical support for the hypothesized hedonic theoretical relation between the price of wine and its quality. The examination considers over 180 hedonic wine price models developed over 20 years, covering many countries. The research identifies that the relation between the price of wine and its sensory quality rating is a moderate partial correlation of +0.30. This correlation exists despite the lack of information held by consumers about a wine’s quality and the inconsistency of expert tasters when evaluating wines. The results identify a moderate price-quality correlation, which suggests the existence of strategic buying opportunities for better informed consumers. Strategic price setting possibilities may also exist for wine producers given the incomplete quality information held by consumers. The results from the meta-regression analysis point to the absence of any publication bias, and attribute the observed asymmetry in estimates to study heterogeneity. The analysis suggests the observed heterogeneity is explained by the importance of a wine’s reputation, the use of the 100-point quality rating scale, the analysis of a single wine variety/style, and the employed functional form. The most important implication from the analysis is the relative importance of a wine’s reputation over its sensory quality, inferring that producers need to sustain the sensory quality of a wine over time to extract appropriate returns. The reputation of the wine producer is found not to influence the strength of the price quality relationship. This finding does not contradict the importance of wine producer reputation in directly influencing prices.

"If you can have one glass of wine now and then, why are you denying that to a woman with no evidence": Knowledge and practices of health professionals concerning alcohol consumption during pregnancy.

BACKGROUND: Alcohol consumption during pregnancy has the potential to cause significant harm to the foetus and the current Australian guidelines state that it is safest not to drink alcohol while pregnant. However, conflicting messages often appear in the media and it is unclear if the message to avoid alcohol is being effectively conveyed to pregnant women. AIMS: This research aims to explore the advice that health professionals provide to pregnant women about alcohol consumption; the knowledge of health professionals regarding the effects of alcohol consumption; and their consistency with following the Australian guidelines. METHODS: Ten semi-structured face to face interviews were conducted with health professionals who regularly provide antenatal care. These include midwives, obstetricians, and shared care general practitioners. A six-stage thematic analysis framework was used to analyse the interview data in a systematic way to ensure rigour and transparency. The analysis involved coding data extracts, followed by identifying the major themes. FINDINGS: Health professionals displayed adequate knowledge that alcohol can cause physical and mental difficulties that are lifelong; however, knowledge of the term FASD and the broad spectrum of difficulties associated with alcohol consumption during pregnancy was limited. Although health professionals were willing to discuss alcohol with pregnant women, many did not make this a routine part of practice, and several concerning judgements were noted. CONCLUSION: Communication between health professionals and pregnant women needs to be improved to ensure that accurate information about alcohol use in pregnancy is being provided. Further, it is important to ensure that the national guidelines are being supported by health professionals.

"My midwife said that having a glass of red wine was actually better for the baby": a focus group study of women and their partner's knowledge and experiences relating to alcohol consumption in pregnancy.

BACKGROUND: While it is well established that alcohol can cross the placenta to the foetus and can affect an infant's development, many women continue to drink during pregnancy. For this reason it is important to determine what information is being provided, what information may be missing, and the preferred sources of information on this issue. In order to improve prevention strategies, we sought to understand the knowledge and experiences of pregnant women and their partners regarding the effects of alcohol consumption during pregnancy. METHODS: The current study utilised a qualitative study design in order to gain insight into the views and experiences of pregnant women, newly delivered mothers and their partners. Focus groups examined the participant's knowledge about the effects of alcohol consumption during pregnancy, the sources of information on this issue, and the psycho-social influences on their drinking behaviour. Five focus groups were conducted involving a total of 21 participants (17 female). A six-stage thematic analysis framework was used to analyse all focus group discussions in a systematic way. RESULTS: Seven major themes were identified from the focus group data: 1) knowledge of Foetal Alcohol Spectrum Disorders; 2) message content and sources; 3) healthcare system; 4) society and culture; 5) partner role; 6) evaluation of risk; and 7) motivation. The findings indicated that although the majority of participants knew not to drink alcohol in pregnancy they had limited information on the specific harmful effects. In addition, routine enquiry and the provision of information by health care professionals were seen as lacking. CONCLUSIONS: The findings of this research provide important insights in to the relationship between pregnant women, their partners, and their healthcare providers. Several recommendations can be made on the basis of these findings. Firstly, public health messages and educational materials need to provide clear and consistent information about the effects of alcohol consumption on the developing baby. Additionally, more thorough and consistent routine enquiry for alcohol consumption in pregnant women needs to occur. Finally, it is important to ensure ongoing education for health professionals on the issue of alcohol consumption during pregnancy.

Recycled effluent irrigation in vineyards : an Australian case study. I. issues and monitoring

The viticultural industry is becoming an increasingly significant part of the Australian agricultural sector, with gross earnings of over $4 billion in 2002. Expansion of the industry in the last decade has been rapid, however its heavy reliance on irrigation has resulted in further expansion in many wine growing regions being limited by the availability of water. This problem is not confined to the viticultural industry, with ever increasing pressures on water resources worldwide. As demands for water continue to rise, new strategies to meet demands must be adopted. One of the strategies being increasingly employed is the recycling of waste waters for a number of applications such as irrigation and industrial uses. The use of recycled water for vineyard irrigation provides a number of benefits. Among them are the reduced demands on potable supplies, reduced waste discharges to surface waters, and the opportunity for expansion of production. Recycled waters however, contain constituents which have the potential to cause deleterious effects to both production and the environment. Therefore, the use of recycled water for irrigation requires targetted monitoring and management to ensure the long-term sustainability of both the vineyard and the surrounding environment. Traditional monitoring techniques including water quality monitoring and soil testing can be complimented by new technologies and techniques which provide large quantities of information with relatively less labour and time. Such techniques can be used to monitor the vineyard environment to identify impacts arising from management practices, allowing vineyard managers to adjust management for sustainable production

Analytical methodology for the determination of urea: current practice and future trends

The determination of urea is important in a wide range of fields, including clinical diagnostics, environmental monitoring and food science. Numerous analytical techniques have been developed for the determination of urea, with no single technique dominant in all areas because of the diversity of applications. An overview of the existing analytical methodologies for urea is presented, and some new approaches are discussed, particularly those based on chemiluminescence detection to improve the sensitivity and the selectivity for the determination of this important analyte.

How well do Australian women comply with dietary guidelines?

Objective: To investigate the proportion of middle-aged Australian women meeting national dietary recommendations and its variation according to selected sociodemographic and behavioural characteristics.

Design: This cross-sectional population-based study used a food-frequency questionnaire to investigate dietary patterns and compliance with 13 commonly promoted dietary guidelines among a cohort of middle-aged women participating in the Australian Longitudinal Study on Women's Health.

Setting: Nation-wide community-based survey.

Subjects: A total of 10 561 women aged 50–55 years at the time of the survey in 2001.

Results: Only about one-third of women complied with more than half of the guidelines, and only two women in the entire sample met all 13 guidelines examined. While guidelines for meat/fish/poultry/eggs/nuts/legumes and ‘extra’ foods (e.g. ice cream, chocolate, cakes, potatoes, pizza, hamburgers and wine) were met well, large percentages of women (68–88%) did not meet guidelines relating to the consumption of breads, cereal-based foods and dairy products, and intakes of total and saturated fat and iron. Women working in lower socio-economic status occupations, and women living alone or with people other than a partner and/or children, were at significantly increased risk of not meeting guidelines.

Conclusions: The present results indicate that a large proportion of middle-aged Australian women are not meeting dietary guidelines. Without substantial changes in their diets, and help in making these changes, current national guidelines appear unachievable for many women.

Monitoring a commercial fermentation with proton nuclear magnetic resonance spectroscopy with the aid of chemometrics

Proton nuclear magnetic resonance spectroscopy (NMR) has shown the potential for being a valuable tool in monitoring a commercial fermentation. In this preliminary study, a suite of organic analytes including ethanol, fructose, glucose, methanol, glycerol, malic acid, tartaric acid, succinic acid, acetic acid and lactic acid were simultaneously determined during the fermentation. Data collection and analysis using chemometric algorithms aided the understanding of key processes including the effects of seeding a wine with bacteria for malo-lactic fermentation.

Determination of urea using high-performance liquid chromatography with fluorescence detection after automated derivatisation with Xanthydrol

A high-performance liquid chromatography (HPLC) method for the determination of urea that incorporates automated derivatisation with xanthydrol (9H-xanthen-9-ol) is described. Unlike the classic xanthydrol approach for the determination of urea, which involves the precipitation of dixanthylurea (N,N′-di-9H-xanthen-9-ylurea), the derivatisation procedure employed in this method produces N-9H-xanthen-9-ylurea, which remains in solution and can be quantified using fluorescence detection (λ_ex = 213 nm; λ_em = 308 nm) after chromatographic separation from interferences. The limit of detection for urea was 5 × 10⁻⁸ M (0.003 mg L⁻¹). This method was applied to the determination of urea in human and animal urine and in wine.

Dietary portfolio approach to reducing the risk of cardiovascular disease : the polymeal revisited

Aims: The Polymeal was first proposed as a 'tastier and safer' alternative to a polypharmacy approach to cardiovascular disease risk reduction. The present study aimed to examine the affordability of the Polymeal, and to propose modifications based on economic considerations, and the latest scientific evidence, to achieve consistency with current public health recommendations.

Methods: Prices for each food component specified in the Polymeal were obtained from a major and independent supermarket chain in a representative middle socioeconomic demographic region of metropolitan Melbourne, Australia. Items included fish (114 g, four times/week), fruits and vegetables (400 g/day), dark chocolate (100 g/day), garlic (2.7 g/day), almonds (68 g/day) and red wine (150 mL/day). Prices were calculated using an average of the major brands, or the most commonly eaten fruits, vegetables or fish. Modifications of the Polymeal were proposed based on published research and public health recommendations since the Polymeal was first proposed.

Results: Average price of the Polymeal was AU$11.89 per day falling to AU$8.46 if the cheapest food items were chosen. Modifications to the Polymeal included: consuming fish oil capsules instead of fish, reduction in the quantity of dark chocolate and removal of red wine. These modifications halved the cost of the Polymeal, while choosing the cheapest food items further lowered the cost to AU$3.49 per day. Modification of the Polymeal gave substantial reductions in both energy and saturated fat (51% and 84%, respectively).

Conclusion: The modified Polymeal is a more affordable variation of the Polymeal, which takes into account current scientific evidence and public health recommendations.

Chemiluminescence as a screening tool for bioactive phytochemicals

The health benefits of antioxidant-rich ‘Mediterranean’ type diets high in grain, olives and red wine are well recognised. Since these foodstuffs consist of a complex matrix of chemical components, to date, the primary challenge lies in prioritising and isolating molecules for a physiologically relevant cell culture assay to assess their human health benefits. Currently, the most common approach requires arduous sample fractionation into smaller ‘crude’ extracts, followed by costly cell culture assays, with the bioactive identified only after a positive response in the cell. The work presented within this poster demonstrates the potential for an acidified potassium permanganate chemiluminescence detector as a much simpler screening tool to identify the best bioactive candidates from a complex sample matrix.

Where do entrepreneurs have the best chances of success? The Asia-Pacific regulatory environment for entrepreneurial Micro And Medium Sized Enterprises (MMES)

Why do some entrepreneurs succeed while others fail in international competition? Perhaps it is better to turn the question around and ask, why is it that a particular country or economy becomes the home base for competitive globally-oriented entrepreneurs? What makes Australia a global leader in wine exports? How did New Zealand make it to global ranks in the creative industries? Why does Singapore have the most businessfriendly environment for entrepreneurs? Why is it “location, location, location”? One of the most powerful factors is the regulatory environment.

Asia-Pacific country-specific and region-specific regulations are diverse, and they seriously affect the climate for start-up entrepreneurs. They range from best-in-the world (e.g. Australia, New Zealand and Singapore) to the dreadful (Indonesia), according to the World Bank. Costs and profits can be affected as much by a government regulation as by a management decision. Fundamental entrepreneurial decisions--such as which lines of business to go into, which products and services to produce and introduce, which investments to finance, how and where to make goods and how to market them, and what prices to charge--are increasingly subject to governmental control.

In this short paper, we examine World Bank and Transparency International data on Asia-Pacific regulatory environments and make statements about how the economies compare to best practice. While I use data collected by other sources, I believe the added value comes through comparing and contrast the regulatory environments of our region in a justifiable and easily understood manner.
