Abstract
In the Taguchi’s experimentations, orthogonal arrays, interaction tables, and linear graphs are provided for planning experiments, but they become quite unwieldy when the number of runs is large. The purpose of this article is to propose a quick and easy method for obtaining two‐factor interaction columns in two‐level orthogonal arrays. Geometrical designs proposed by Plackett and Burman are two‐level orthogonal arrays and can be obtained very easily by a successive doubling method. Based on the property of doubling, a NR method using a number representation system whose base is a power of 2 is derived in this article for obtaining two‐factor interaction columns in geometrical designs. Furthermore, since Taguchi’s two‐level orthogonal arrays are obtainable by successive doubling with some column permutations, it is shown that their two‐factor interaction columns can be obtained directly by using the NR method without looking up tables.

Abstract
The use of the L12 orthogonal array has been highly recommended in Taguchi’s experimentation; however, it has very complex partial aliasing patterns (PAP). Proposes a method based on the inner product (IP) of vectors for computing the PAP of an interaction. Provides some special tables, which give the values of IP for three‐factor, four‐factor and five‐factor so that the PAP for any order of interaction can be obtained easily. Discusses some interesting properties of the PAP.

This study aims to develop a highly interactive exhibition guiding system which enables both authors and visitors to interact with one another on an exhibition site.
Abstract
Purpose
This study aims to develop a highly interactive exhibition guiding system which enables both authors and visitors to interact with one another on an exhibition site.
Design/methodology/approach
The guiding system was designed with a “pull‐type” concept in a way that a handheld device must be close to a specific work to “pull” the information out of that work. The highly interactive functions between visitors and authors or among visitors were enabled by the Web 2.0. Verification and validation of the system's functions were tested in an art gallery with PDAs utilizing passive RFID readers and tags. A questionnaire survey was conducted to learn of the opinions from authors and visitors after they used the system.
Findings
The verification and validation test showed that all the functions have met the predefined requirements. The results of the questionnaire survey also revealed that the majority were satisfied with the interactive guiding system.
Practical implications
Not only can the system perform the guide tasks well, but it also allows the users to select interested modules so as to avoid overloading the irrelevant information. Additionally, the visitors can chat with unacquainted visitors who are onsite and have the same taste on a specific artwork, and the authors can visualize the visitors' comments, recommendations, and suggestions on their works in a real‐time manner.
Originality/value
The paper shows that the proposed system has some innovative features. It enables the authors to interact with the visitors, to understand the visitors' thoughts and opinions on their works, and to share the ideas of their creativity with the interested visitors onsite. On the other hand, it also enables the visitors to interact with the authors and other visitors. The visitors can recommend appreciated works to others, provide their comments and suggestions, visualize others' comments and suggestions, and exchange their views with those who are onsite and even recommend the same works.

Abstract
Purpose
The purpose of the present study is to understand the diversity management concept in Taiwan setting by providing a closer look into local companies’ practices. Rational and focus for this research exploration is based on three areas related to diversity management in organizations: external and internal pressures for diversity in Taiwanese companies; companies’ approaches and senior leadership attitude toward diversity; companies’ diversity management practices.
Design/Methodology/Approach
The authors have collected secondary and primary data, including 15 interviews with management, at three large Taiwan semiconductor companies and build a case study of diversity management in Taiwan.
Findings
Taiwan companies’ diversity management is motivated mainly by business case and social responsibility goals. They experience a need for diversity management and proactively introduce diversity management policies.
Research Limitations/Implications
Further studies should look into diversity management practices of smaller private/family-owned companies in Taiwan to get a deeper understanding of the concept in the country using quantitative and qualitative approaches.
Originality and Value
Taiwan is historically culturally homogeneous society, which undergoes massive demographic changes under the influence of low birth rate and high rate of immigration. Taiwan situation creates specific economic, cultural, and political context for diversity management that differs from other Asian, European or Western societies.

Abstract
Purpose
Food labels are increasingly used to provide information to consumers. As a common design strategy used for food package labels globally, label frame is often used to expand the perceived breadth of a brand and create a broader brand image. We evaluated the effect of the presence or absence of a non-genetically modified organism (non-GMO) label frame on consumers' preferences for non-GMO foods.
Design/methodology/approach
This study collected data from 120 MBA students at a university in Sichuan, China, and 126 foreign volunteers in a shopping mall in Chengdu, Sichuan Province. The study investigates the effect of the presence or absence of non-GMO label frame (i.e. label with or without an outline) on non-GMO food preferences through a field survey and two controlled experiments. To empirically analyse the psychological mechanisms by which non-GMO label frames affect consumers' preferences for non-GMO food, we set up the mediating variable of food association of safety.
Findings
For ordinary consumers, a framed non-GMO label is more likely to evoke food association of safety and further enhance consumer preference for non-GMO foods. It facilitates consumers' choice of healthier foods. This finding did not otherwise vary across demographic characteristics.
Originality/value
This study is the first to examine the influence of non-GMO label frames on consumers' non-GMO food preferences, which is an innovative research question. The findings of this study are instructive for food manufacturers and policymakers to better design and use non-GMO label frames to attract more consumers to choose non-GMO foods.
