Adapted or standardized copy: Is non-cultural English the answer?

International advertisers often wonder whether to adapt their copy to each country they operate in or to globally standardize their message, especially in non-Anglophone markets. While the current business lingua franca is English, how easily can it be introduced into advertising without alienating consumers, and would a simpler English message work better? Does the culture of a brand also influence the impact of English use in non-Anglophone markets? This research examines the interaction between language choice and brand culture in a non-Anglophone market. Specifically, the studies review the value of Globish, a non-cultural form of English. The results suggest that using standardized English copy has relevance in non-Anglophone countries for global brands, but that Globish can also be useful for local brands seeking to upgrade their value in a local market. Globish is shown to be an interesting alternative option in adapting or standardizing advertising strategies. Managerial implications close the paper.     

Toward Deepening Cultural and Language Understanding: The Design and Practice of a Hybrid Business Chinese Course

This article introduces an ongoing effort to use Internet resources in an Advanced Business Chinese for Professionals (ABCP) course in order to deepen learners’ language and cultural understanding. This course blends face-to-face (F2F) classroom instruction and online communications using Brix, an online course management system developed by the University of Hawai‘i. This article starts with the rationale and necessity of a hybrid course for ABCP and presents an overview of a traditional F2F business Chinese class with its strengths and weaknesses. Following the overview, this article outlines the design of a hybrid environment for this course, detailing its structure, content, and instructional processes. Illustrations of the F2F and online alternations in classroom teaching, online tasks with instructor’s guidance and feedback, and online forum discussion for each unit are offered. Experiences gained in this process regarding instructional intervention, projected learners’ learning outcomes, and interactive peer learning through the Internet will also be shared. Reflections and suggestions on aspects that may impact the success of this approach are proposed for future improvement in an ideal hybrid business language course.

A valued agent: How ECAs affect website customers' satisfaction and behaviors

Building on literature related to selling and embodied conversational agents (ECA), this research seeks to determine how the use of an ECA might improve users’ perceptions of shopping value (hedonic and utilitarian) and the consequences for their purchase intentions and satisfaction with the website. This analysis focuses specifically on three ECA usage consequences: playfulness, decision quality, and social presence. Hedonic value mediates the effects of playfulness and social presence on satisfaction and behavioral intentions; utilitarian shopping value mediates the effects of decision quality. The results highlight the importance of accounting for both utilitarian and hedonic features to understand ECA outputs in e-commerce sites.     

Antecedents and consequences of the perceived adjustment of Japanese expatriates in the USA

The present study was designed to better understand the antecedents and consequences of expatriate adjustment in an international assignment. The researchers surveyed Japanese expatriates assigned to the United States. Structural equation modeling was utilized to test our hypotheses and model. The results indicated that previous knowledge of the host country, language proficiency, willingness to communicate and perception of the novelty of the host culture were differentially related to expatriates' adjustment to the host country. General and work adjustments were negatively related to expatriates' intent to return early. In addition, interrelationships among the adjustment dimensions were examined and the results indicated that general adjustment leads to work adjustment, which, in turn, influences interactional adjustment. Implications for future research are presented.
