Abstract

Purpose

Food choices profoundly affect one's dietary, nutritional and health outcomes. Using alcoholic beverages as a case study, the authors assess the potential of genetic data in predicting consumers' food choices combined with conventional socio-demographic data.

Design/methodology/approach

A discrete choice experiment was conducted to elicit the underlying preferences of 484 participants from seven provinces in China. By linking three types of data (—data from the choice experiment, socio-demographic information and individual genotyping data) of the participants, the authors employed four machine learning-based classification (MLC) models to assess the performance of genetic information in predicting individuals' food choices.

Findings

The authors found that the XGBoost algorithm incorporating both genetic and socio-demographic data achieves the highest prediction accuracy (77.36%), significantly outperforming those using only socio-demographic data (permutation test p-value = 0.033). Polygenic scores of several behavioral traits (e.g. depression and height) and genetic variants associated with bitter taste perceptions (e.g. TAS2R5 rs2227264 and TAS2R38 rs713598) offer contributions comparable to that of standard socio-demographic factors (e.g. gender, age and income).

Originality/value

This study is among the first in the economic literature to empirically demonstrate genetic factors' important role in predicting consumer behavior. The findings contribute fresh insights to the realm of random utility theory and warrant further consumer behavior studies integrating genetic data to facilitate developments in precision nutrition and precision marketing.

Abstract

There has been extensive research conducted regarding the identification of evaluative criteria and cues used in selecting products classified as goods, yet there has been little research on products classified as services. Marketing managers accept the notion that there are some controllable and uncontrollable variables in the environment that will impact on the consumer's perceptions of their product offering. If marketers can understand which criteria are used to evaluate a product, in this case a service, and can identify which cues are used to assess the criteria, they will he better able to manage and influence the consumer's evaluations and perceptions of the offering. This study takes an integrated look at the evaluative criteria and cues used by consumers in selecting services.

Abstract

This article investigates whether a negative country of origin bias facing imported wine can be offset when it is distributed in marketing channels alongside already accepted complimentary products. Specifically we consider the case of Mexican wine being introduced to consumers in a Mexican restaurant versus a more general themed contemporary restaurant. An experimental design was employed to investigate consumers' perceptions and future purchase intentions after tasting Mexican wine in a proposed restaurant with one of the two themes. Findings suggest that the best method for introducing Mexican wine to US consumers may be through Mexican restaurants although adoption of the wine for consumption at home may be slow.

Abstract

Wine marketers realise that to increase the overall size of the wine consuming population they must make wine more approachable and easier to understand. As it now stands, many consumers lack confidence in their ability to select a wine for either their own consumption or to share with others. Therefore, understanding the role played by consumer self‐confidence is especially relevant to marketers of wine, and the need to accurately measure the construct is important to scholarly research. Recently, the development of a scale to measure consumer self‐confidence has appeared in the consumer behaviour literature (Bearden, Hardesty and Rose, 2001). This study first adapts this consumer self‐confidence scale for use in wine‐related research. Next, the impact of six distinct dimensions of consumer self‐confidence on three different wine purchase situations is demonstrated. Results show the scale has the potential to inform both researchers and marketers about consumers' self‐confidence related to wine purchases.

Abstract

This study is an exploratory examination of cultural differences in accounting educators’ epistemological beliefs of accounting ethics education. It is motivated by a renewed global interest in accounting ethics in recent years following the reported breaches of ethical conducts by individuals from different cultures. In Pratt’s model, conceptions of teaching should be an interdependent and internally consistent trilogy of beliefs, intentions and actions. The purpose of this empirical study is to sketch an outline of how accounting ethics education is broadly understood by accounting educators from three different cultural backgrounds, the Anglo‐influenced Australian, the Chinese and the Moslem‐dominated Malaysian. It explores the cross‐cultural variations in their epistemological beliefs of what to teach, objectives to achieve, the ethics educator, and the learning process. Results suggest that Australian and Malaysian accounting educators differed significantly in their epistemological beliefs on the source of knowledge as well as the acquisition of knowledge. Interestingly, there were no significant statistical differences in the epistemological beliefs held by participants in this study concerning other issues in accounting ethics education, i.e. the delivery of ethics education, transferability, goals of ethics education, separate course, and qualification.

Abstract

Purpose

The purpose of this paper is to examine the relationships between product‐ and store‐related attributes of eco‐fashion and fashion consumers’ eco‐fashion consumption decisions; and if such relationships are subject to the price premium level of eco‐fashion.

Design/methodology/approach

A survey was conducted with consumers in Hong Kong: in total, 216 consumers participated in the survey. A confirmatory factor analysis was conducted to check the validity and reliability of the scales. Hypotheses were tested using multiple regression analysis.

Findings

The findings showed that only store‐related attributes of eco‐fashion positively influence consumers’ eco‐fashion consumption decision, yet, such relationship can be weakened by the price premium level of eco‐fashion.

Research limitations/implications

Fashion consumers’ response to product‐ and store‐related attributes of eco‐fashion is still important in predicting fashion consumers’ eco‐fashion consumption decision. Fashion consumer environmental attitudes can predict fashion consumers’ eco‐fashion consumption decision better than fashion consumers’ attitude towards eco‐fashion.

Practical implications

It is not enough for fashion companies to manufacture fashion clothing in an ethical production system and develop and design fashion clothing with sustainable and recyclable materials. They must also improve store‐related attributes of eco‐fashion to better satisfy fashion consumer needs, and should be cautious in the direct and moderating effect of price premium level of eco‐fashion when determining the price premium level of eco‐fashion.

Originality/value

The paper contributes to research by advancing understanding on how consumers make ethical consumption decisions in purchasing fashion, and provides retailers with managerial insights into devising marketing plans to promote eco‐fashion consumption, which facilitate fashion companies’ development of a sustainable fashion supply chain. Limitations and directions for future research are also presented in the paper.

Abstract

Purpose

The purpose of this paper is to develop a physics-based model for UAV propellers that is capable of predicting all aerodynamic forces and moments in any general forward flight condition such as no flow, pure axial flow and pure side flow etc.

Design/methodology/approach

The methodology adopted in this paper is the widely used Blade Element Momentum Theory (BEMT) for propeller model development. The difficulty arising from the variation of induced flow with blade’s angular position is overcome by supplementing the BEMT with the inflow model developed by Pitt and Peters. More so, high angle of attack aerodynamics is embedded in the simulation as it is likely for the blades to stall in general forward flight, for example during extreme aerobatics/maneuvers.

Findings

The validity of the model is demonstrated via comparison with experiments as well as with other existing models. It is found that one of the secondary forces is negligible while the other is one order of magnitude less than the primary static thrust, and as such may be neglected depending on the level of accuracy required. On the other hand, both secondary moments must be considered as they are of similar order of magnitude as the primary static torque.

Research limitations/implications

The paper does not consider the swirl component of the induced flow under the assumption that it is negligible compared to the axial component.

Originality/value

This paper fulfills the identified need of a propeller model for general forward flight conditions, and aims to fill this void in the existing literature pertaining to UAVs.

Abstract

Demand for US wine imports, import planning process. Nerlovian adjustment model, short and long run elasticities, forecast The increase in wine imports, poses questions about a possible trend, and its implications for future investment opportunities of US wine companies in other wine producing countries. This article presents a model to explain the demand for wine imports in the US. Using econometric procedures we estimate coefficients of the major explanatory factors such as relative wine import prices, exchange rates, real per capita income, wine production capacity, and population. The model is used to forecast likely wine import volumes from 2003 to 2012. Even under conservative assumptions about trends of those explanatory variables we predict an important increase in US wine imports.
