The effort in addition to relevance is a major factor for satisfaction and utility of the document to the actual user. The purpose of this paper is to propose a method in generating relevance judgments that incorporate effort without human judges’ involvement. Then the study determines the variation in system rankings due to low effort relevance judgment in evaluating retrieval systems at different depth of evaluation.

Effort-based relevance judgments are generated using a proposed boxplot approach for simple document features, HTML features and readability features. The boxplot approach is a simple yet repeatable approach in classifying documents’ effort while ensuring outlier scores do not skew the grading of the entire set of documents.

The retrieval systems evaluation using low effort relevance judgments has a stronger influence on shallow depth of evaluation compared to deeper depth. It is proved that difference in the system rankings is due to low effort documents and not the number of relevant documents.

Hence, it is crucial to evaluate retrieval systems at shallow depth using low effort relevance judgments.

Brand pages are a very popular tool for companies to communicate with consumers in SNSs. Although brand pages could be considered virtual brand communities, they differ in several aspects. Thus, this chapter reviews the literature on brand pages attending to the main differences with other virtual communities, the motivations to join brand pages and its consequences for consumers and brands.

The studies reviewed have allowed us to identify the main characteristics of brand pages as a communication tool, as well as the definition of an important research agenda for this topic.

We have identified the main unique aspects that characterize brand pages as a virtual brand community. The motivations to become members of brand pages are analyzed as well as the positive consequences of these pages on the marketing variables. We also identified the research needs on brand pages.

This chapter can be useful to both, marketers, by showing them how brand pages work and what motivate consumers to join it; and researchers, by showing them the main gaps on brand pages that should be addressed in future studies.

This chapter highlights the role of brand pages as a communication tool. It constitutes an attempt to review the literature and organize knowledge on brand pages. The characteristics of brand pages and virtual brand communities, the motivations to participate, the consequences for the brand and an important research agenda are developed.

Government policy mandates information disclosure in financial communications to protect consumer welfare. Unfortunately, low readability can hamper information disclosures’ meaningful benefits to financial decision making. Thus, this experiment tests the product evaluation and decision satisfaction of Korean consumers with less or more subjective knowledge and with or without personal finance education.

A between-subjects experiment examined responses of a nationally representative sample of 400 Korean consumers toward a Korean-language credit card advertisement.

Financial knowledge improves financial product evaluation and decision satisfaction. More readable disclosures improved evaluation and satisfaction among less knowledgeable consumers. Less readable disclosures did not. Consumers without financial education exhibited lower evaluations and decision satisfaction regardless of readability. More knowledgeable consumers and those with financial education performed equally well regardless of disclosure readability.

Financial service providers seeking more accurate evaluations and better decision satisfaction among their customers should use easier-to-read disclosures when targeting consumers with less prior financial knowledge.

One-size-fits-all financial communications are unlikely to achieve public policy or consumer well-being goals. Government-mandated information should be complemented by augmenting financial knowledge and providing personal finance training.

Although almost a quarter of the world’s population lives in East Asia, this is the first examination of readability in disclosures written in East Asian characters rather than a Western alphabet. Previous readability research on Asian-originating financial disclosures has been conducted on English-language texts. This study extends knowledge of readability effects to growing East Asian markets.

The purpose of this research was to develop clothing-typed soft wearable robot embedded with textile-based actuators on ankles for elderly adults needing gait assistance.

Design guidelines were developed and they included function (type, targeting area, routing line and anchor points), design (size/fit, fabric/material, fastener, detail, color) and actuator (shape memory alloy type, size, deformation type, integration material, integration technique and evaluation method). Fabric-based actuator, integration methods to fabrics, routing lines and anchoring points were developed based on the guidelines and evaluated. Then, three long socks types and a pants type were designed and prototyped. Routing line position displacement measurement test was conducted with the prototypes. A survey was conducted to investigate satisfaction, likeness and use intention on the design/prototype to modify the designs.

Important design factors were identified, and design guidelines for clothing-typed soft wearable robots (SWRs) were developed. People satisfied the developed SWR designs and prototypes with mean scores over 4.60.

The results are expected to be helpful for designers and developers of SWRs in the development process, and they will ultimately be beneficial to members of the elderly population who have gait difficulties.

The present research aimed to develop and test cognitive processes through which instrumental leadership leads to creativity via problem-solving rumination and knowledge sharing with coworkers, based on the self-regulatory perspective of goal progress theory.

Data were collected from 166 male construction workers (nested within 19 male leaders) who completed the total of 1,642 daily diary questionnaires. Further, a group-mean centering approach and several control variables were used in order to improve causal inferences of the results.

It was found that instrumental leadership predicts problem-solving rumination (an intrapersonal self-regulatory process) and knowledge sharing with coworkers (an interpersonal self-regulatory process), which, in turn, result in creativity.

In addition to motivational processes that explain the relationships between several leadership styles and creativity, the current research found a crucial role of instrumental leadership in predicting creativity.

The purpose of this study is to assess the possibility of introducing a restaurant-menu curation (RMC) chatbot service to help consumers quickly and effectively decide on their restaurant or menu choices. To this end, it measures the characteristics of consumer chatbot experiences and analyzes their impact on future acceptance intentions through their attitudes toward the RMC chatbot service.

This study consists of three parts: developing a RMC chatbot prototype, testing the chatbot prototype and a customer survey based on experience. A convenience sample method was used to collect data from 368 adults who tried the RMC chatbot service before answering a self-administered questionnaire. Partial least squares structural equation modeling (PLS-SEM) was used to test the proposed structural model.

The results showed that all experience characteristics, except usable facets, had a significant positive impact on attitudes toward the chatbot. Three experience characteristics, “usable,” “usefulness” and “valuable,” revealed a significant positive effect on utilization intention. Attitudes toward chatbot services also significantly affected utilization intention.

The results of this study can offer practical and academic implications for establishing curation services in the restaurant industry that can increase customer acceptance and utilization intentions. Follow-up studies are required to explore and verify the various personal and psychological factors related to the intention to accept RMC chatbot services.

This study is meaningful because it makes it possible to evaluate the introduction of curation chatbot services in the restaurant sector, by developing and testing the dining-out curation service protocol to help customers’ smart choices in the information technology environment.

The purpose of this paper is to determine the influences of fat content and storage temperature on the quality of frozen pork patties during storage to evaluate the shelf life set by the manufacturer.

Changes in moisture content, acid value, peroxide value, thiobarbituric acid value, total volatile basic nitrogen content, and the sensory score of frozen pork patties with 10 and 15 percent fat contents during storage at −5, −15, and −23°C for six months.

Although microbiological quality remained unchanged, moisture content decreased, and lipid rancidity and protein putrefaction increased significantly during storage. More rapid deterioration in quality was observed in patties stored at −5°C than those stored at lower temperatures. Lipid rancidity and protein putrefaction increased more rapidly (but not significantly) in patties with 15 percent fat than those with 10 percent fat. Overall acceptance of the sensory properties was closely correlated with the above quality indicators, except thiobarbituric acid value. Acceptable qualities of the samples were maintained for the first two, four, and six months under storage at −5, −15, and −23°C, respectively.

The current shelf life of frozen pork patties set by manufacturers, assuming a storage temperature of −18°C, needs to be readjusted considering practical storage temperatures.

No studies have comprehensively explored the effects of fat content and storage temperatures on the quality of ground meat products during frozen storage. These approaches to determine quality changes may be useful for manufacturers to predict and control the quality of their products.

From 1953 to 1961, the South Korean economy grew slowly; the average per capita GNP growth was a mere percent, amounting to less than $100 in 1961. Few people, therefore, look for the sources of later dynamism in this period. As Kyung Cho Chung (1956:225) wrote in the mid‐1950s: “[South Korea] faces grave economic difficulties. The limitations imposed by the Japanese have been succeeded by the division of the country, the general destruction incurred by the Korean War, and the attendant dislocation of the population, which has further disorganized the economy” (see also McCune 1956:191–192). T.R. Fehrenbach (1963:37), in his widely read book on the Korean War, prognosticated: “By themselves, the two halves [of Korea] might possibly build a viable economy by the year 2000, certainly not sooner.”

The purpose of this paper are to examine: first, whether the consumer style inventory (CSI) consumer decision-making styles were related to opinion seeking using electronic word of mouth (eWOM) in social networking sites (SNSs) and attitudes toward online social shopping using SNSs; and second, whether opinion seeking in SNSs and attitudes mediated the links between decision-making styles and intent to social shop online for apparel using SNSs.

The conceptual foundation was based on Engel, Kollat, and Blackwell's model. In total, 304 college students who are SNS users provided usable responses. Structural equation modeling was employed to test the proposed model and research hypotheses.

Among the CSI consumer decision-making styles, novelty/fashion consciousness decision-making style was the most important antecedent of opinion seeking using eWOM. The brand consciousness decision-making style was the most important antecedent of favorable attitudes. Novelty/fashion consciousness, brand consciousness, and price consciousness decision-making styles had indirect effects on intent to social shop online for apparel using SNS, mediated by both opinion seeking and favorable attitudes.

This study contributes to further theoretical understanding of the types of consumers that are drawn to eWOM and their online social shopping behaviors for apparel using SNSs. By identifying individual consumer characteristics, this study can provide retailers with an initial profile of consumers who shop apparel using SNSs. Retailers can use this information to further develop the design of their social shopping sites using SNSs to meet the needs of their customers.
