On the development and application of a self–organizing feature map–based patent map

Recently, the range of R&D management has expanded to include management of technological assets such as technology information, product/process data, and patents. Among others, patent map (PM) has been paid increasing attention by both practitioners and researchers alike in R&D management. However, the limitation of conventional PM has been recognized, as the size of patent database becomes voluminous and the relationship among attributes becomes complex. Thus, more sophisticated data–mining tools are required to make full use of potential information from patent databases. In this paper, we propose an exploratory process of developing a self–organizing feature map (SOFM)–based PM that visualizes the complex relationship among patents and the dynamic pattern of technological advancement. The utility of SOFM, vis–à–vis other tools, is highlighted as the size and complexity of the database increase since it can reduce the amount of data by clustering and visualize the reduced data onto a lower–dimensional display simultaneously. Specifically, three types of PM, technology vacuum map, claim point map, technology portfolio map, are suggested. The proposed maps may be used in monitoring technological change, developing new products, and managing intellectual property.     

Does franchising help restaurant firm value?

A company's financial performance is of keen interest to many groups of people, including management, employees, shareholders, government, and so on. Although franchising has been one of the most common strategies to maximize a firm's financial performance in the restaurant industry, little research has been conducted regarding the relationship between the degree of franchising and the restaurant firm's financial performance. This study initially proposed a sigmoid relationship between the degree of franchising and the restaurant firm's financial performance based on the diversification theory. Findings, however, do not fully support the sigmoid relationship; rather a more quadratic or inverted U-shaped relationship was found.     

Understanding responses to comedic advertising aggression: the role of vividness and gender identity

As the use of comedic aggression in advertising has become more frequent, questions about the boundary conditions of its effectiveness become more important. Issues related to the vividness of the aggression, unique audience responses, and legitimacy of the aggression are examined here as potential influences on the impact of comedic advertising aggression. Two experiments are reported that explore how reactions to comedic advertising aggression are influenced by components of vividness (concreteness – aggressive intensity, emotional interest – psychological distance), the audience's gender identity, and whether the aggression was provoked and justified. Feminine identity individuals in close psychological situations react quite negatively to advertising using the highest level of comedic aggression while masculine identity individuals actually prefer the most vivid aggression in some conditions. The response patterns become different for feminine and masculine identity individuals when the aggression is unprovoked and therefore less justified. The results provide guidance about the limits of using comedic advertising aggression.     

An approach to discovering new technology opportunities: Keyword-based patent map approach

This paper proposes an approach for creating and utilizing keyword-based patent maps for use in new technology creation activity. The proposed approach comprises the following sub-modules. First, text mining is used to transform patent documents into structured data to identify keyword vectors. Second, principal component analysis is employed to reduce the numbers of keyword vectors to make suitable for use on a two-dimensional map. Third, patent ‘vacancies’, defined as blank areas in the map that are sparse in patent density but large in size, are identified. The validity of the vacancy is then tested against such criteria as technological criticality and technological trends. If a vacancy is judged as meaningful, its technological features are investigated in detail to identify the potential for new technology creation. The procedure of the proposed approach is described in detail by employing an illustrative patent database and is implemented into an expert system for new technology creation.     

A regression model of the heteroscedastic error variance

We introduce a regression model of the heteroscedastic error variance. A repetitive use of the least squares method is shown to provide the best linear unbiased estimator of the parameter vector of the model.     

Ubiquitous computing and its effects on small businesses

Much of the previous literature on ubiquitous computing (UbiComp) has been limited to case studies, reporting innovative practices of specific technologies (e.g., RFID) and social issues. There is a general paucity of research on strategic application of UbiComp, especially to small businesses. To address this issue, this study provides a broad overview of the current practices of UbiComp in leading countries and presents possible future directions. Then, the effects of UbiComp on small businesses are discussed. Through a cross-national comparative analysis, we present four strategies to provide some guidance to the countries that are currently considering entering into the UbiComp race.     

Affective and continuance commitment and their relations with deviant workplace behaviors in Korea

This study examined the nature of the relations between affective and continuance components of organizational commitment (Meyer & Allen, 1991, Human Resource Management Review, 1: 61–89) and deviant workplace behaviors (DWB; Bennett & Robinson, 2003) in a sample of 120 Korean employees and their supervisors. As expected, we found that affective commitment was negatively related, and continuance commitment was positively, albeit modestly, related to supervisor ratings of DWB. Implications for the theory and practice are discussed.     

INVESTIGATING DIFFERENCES IN ANTECEDENTS TO VALUE BETWEEN FIRST‐TIME AND REPEAT FESTIVAL‐GOERS

This study aimed to capture the underlying quality dimensions (value antecedents) that distinguish between first‐timers and repeaters and that cultivate festival loyalty. Structural relationships were analyzed across the quality dimensions, value, and loyalty for first‐time and repeat visitors. Structural equation modeling revealed that program and convenient facilities alone were antecedents to value for repeaters, whereas food and souvenir, as well as program and convenient facilities, were value antecedents for first‐timers. Specifically, repeat visitors showed stronger relationships on program value and convenient facility value than did first‐time visitors. On the other hand, first‐time visitors associated more strongly with relationships on food value and souvenir value than did repeat visitors. This distinction resulted in a stronger value‐loyalty relationship for repeat visitors than for first‐time visitors. These findings contribute to the understanding of festival‐attendee behavior and thus, provide researchers and practitioners with insights into how to design a festival in such a way that promotes repeat visitors.     

The Moderating Role of Gender Identity in Responses to Comedic Violence Advertising

Comedic violence advertising has been increasing in the United States, but many studies thus far have been content analytic in nature. To gain a better understanding of who will find comedic violence ads humorous and thus have favorable brand perceptions, two experimental studies were conducted with gender identity as an influential factor. In Study 1, masculine individuals responded more favorably to highly violent and humorous ads than feminine individuals did. Study 2 varied the violence level in the comedic violence ads and found that when violence was low both masculine and feminine individuals responded similarly to the comedic violence ad, but when violence was high masculine individuals responded more favorably than did feminine individuals. Perceived humor was found to be an important mediator of comedic violence ad processing. Theoretical and practical implications of the findings are provided.
