Linking Wine Preferences to the Choice of Wine Tourism Destinations

Abstract: This article explores the links between wine consumers’ preferences for wine from particular countries or regions and their interest in, and propensity to travel to, specific wine regions. Data from a convenience sample of 161 wine consumers in Calgary, Canada, revealed that specific appellation-of-origin preferences (e.g., for Australian or French wines) do have an influence on travel preferences and patterns. Nearly 70% of respondents preferred to drink wines from particular origins, and planned wine-related travel by respondents closely matched those geographic preferences. Other factors, however, were also shown to be important in shaping wine tourism destinations, including distance and cognitive factors. Implications are drawn for wine tourism marketing and for destination-choice theory. Recommendations are made for future research.

Occupational stress in university staff.

Abstract: 2A survey was conducted of all staff members of an established Australian metropolitan university. The overall response rate for noncasual staff was 72% (77% for general staff and 65% for academic staff) resulting in a sample of N = 2,040. High levels of psychological stress were observed, despite the fact that trait anxiety and job satisfaction were normal. Psychological distress was highest and job satisfaction lowest among academic staff engaged in both teaching and research. In general, university staff reported high levels of autonomy and social support from colleagues. However those engaged in both teaching and research reported increased pressure arising from funding cuts to universities, resulting in heavier teaching loads and greater difficulty in securing research funds, as well as a decline in facilities and support for both teaching and research. The results are discussed in relation to the Demand–Control and Person–Environment Fit models of job stress.

Board Age and Gender Diversity: A Test of Competing Linear and Curvilinear Predictions

Abstract: The inconsistent findings of past board diversity research demand a test of competing linear and curvilinear diversity–performance predictions. This research focuses on board age and gender diversity, and presents a positive linear prediction based on resource dependence theory, a negative linear prediction based on social identity theory, and an inverted U-shaped curvilinear prediction based on the integration of resource dependence theory with social identity theory. The predictions were tested using archival data on 288 large organizations listed on the Australian Securities Exchange, with a 1-year time lag between diversity (age and gender) and performance (employee productivity and return on assets). The results indicate a positive linear relationship between gender diversity and employee productivity, a negative linear relationship between age diversity and return on assets, and an inverted U-shaped curvilinear relationship between age diversity and return on assets. The findings provide additional evidence on the business case for board gender diversity and refine the business case for board age diversity.

Probing the Surface Hydration of Nonfouling Zwitterionic and PEG Materials in Contact with Proteins.

Abstract: Zwitterionic polymers and poly(ethylene glycol) (PEG) have been reported as promising nonfouling materials, and strong surface hydration has been proposed as a significant contributor to the nonfouling mechanism. Better understanding of the similarity and difference between these two types of materials in terms of hydration and protein interaction will benefit the design of new and effective nonfouling materials. In this study, sum frequency generation (SFG) vibrational spectroscopy was applied for in situ and real-time assessment of the surface hydration of the sulfobetaine methacrylate (SBMA) and oligo(ethylene glycol) methacrylate (OEGMA) polymer brushes, denoted as pSBMA and pOEGMA, in contact with proteins. Whereas a majority of strongly hydrogen-bonded water was observed at both pSBMA and pOEGMA surfaces, upon contact with proteins, the surface hydration of pSBMA remained unaffected, but the water ordering at the pOEGMA surface was disturbed. The effects of free sulfobetaine, free PEG chains with two different molecular weights, and PEG coated gold nanoparticles on the surface hydration of proteins were investigated. The results indicated that free sulfobetaine could strengthen the protein hydration layer, but free PEG chains greatly disrupt the protein hydration layer and likely directly interact with the protein molecules. In contrast to free PEG, the PEG chains anchored on the nanoparticles behave similarly to the pOEGMA surface and could induce strong hydrogen bonding of the water molecules at the protein surfaces.
