The purpose of this paper is to compare the acceptance ratings and drivers of liking and disliking attributes of aseptic-packaged cooked rice by consumers, researchers and experts.

Descriptive analysis (DA) was conducted using trained panelists. Acceptability was measured by consumers, researchers and experts. The results of DA and acceptability were analyzed using partial least square regression.

There was no strong relationship among the three groups in their rating patterns for the samples (r=−0.342-0.445). The liking factors for each group were as follows: consumers (rice cake flavor and moisture), researchers (wet wood flavor and whiteness) and experts (wet wood flavor and size of rice). The disliking factors for each group were as follows: consumers (wet wood flavor and brown particle), researchers (moisture) and experts (old rice aroma). The consumers, researchers and experts seemed to have different acceptances and key descriptive attributes for aseptic-packaged cooked rice.

The consensus by researchers during the product development process required caution with regard to the fact that the evaluation by the researchers could be different from what consumers or experts prefer.

Setting-up in-house panelists group would be minimized the discrepancy between consumers and researches.

This study contributes to understanding of the acceptability by food researchers and comparing to consumers and experts for the first time in sensory field.

To better respond to user needs for personalized information services in the context of academic libraries, this study aims at developing a prototype to provide mobile curation services by using the concept of content curation.

This study used a mobile application software development process, which consisted of five phases: user and organizational requirements, architecture design, navigation design, page design and implementation and usability testing. Usability testing was conducted with a total of 20 college students by online surveys at a university.

Meta-analysis identified key user needs: diversification of services, more personalized services, active communication with librarians, quality improvement of information and interface improvement. User and organizational requirements derived four main service modules – namely, Curation Services, Live Chat, My Page and My Log. Usability testing regarding ease of use, perceived usefulness and satisfaction indicated that participants were satisfied with the prototype.

The study extends the discussion of quality academic library services by introducing the concept of content curation that uses the advantages of mobile technologies to overcome existing limitations in library services insufficient for meeting individual user needs.

Although many studies have discussed mobile library services, few studies have focused on developing a system for such services. The model developed in the study fills the research gap. Above all, the key modules specified by the prototype – Curation Services, Live Chat, My Page and My Log services – are expected to improve existing research and learning support services currently offered by academic libraries.

The phenomenon of mobile social networking site (SNS) addiction has become increasingly severe nowadays and brings adverse outcomes to users’ daily life and work efficiency. However, there are relatively few research probes into the formation process of mobile SNS addiction behavior, and how demographic factors (e.g. gender and age) influence users’ addiction behavior. Adopting the stimulus–organism–response (S–O–R) framework, this study examines the effects of three types of technological functions (enjoyment, sociability and information value) on flow in relation to mobile SNS addiction. The authors further proposed gender and age as moderators, which play important roles in influencing the formation of mobile SNS addiction behavior.

This study examines the formation of mobile SNS addiction with a particular focus on the WeChat app. The authors use a field survey study conducted in China with 351 subjects of WeChat app users to examine thestudy model.

The results demonstrate that addictive behavior is determined by users’ flow states of using mobile SNS. The flow states, in turn, are influenced by three types of technological functions (enjoyment, sociability and information value). In addition, gender and age act as vital moderators in the model.

First, the authors empirically examine the formation of SNS addiction on the mobile device by adopting the S–O–R framework, which may enrich the addiction literature. Second, the authors reveal the moderating roles of age and gender in affecting the formation process of addiction behavior further. The findings of this research deepen our understanding of users’ addiction behavior. Third, the findings also offer rich insights to prevent mobile SNS addiction.

The purpose of this paper is to numerically investigate the effect of guide vane unsteady passing wake on the rotor blade tip aerothermal performance with different tip clearances.

The geometry and flow conditions of the first stage of GE-E3 high-pressure turbine have been used to obtain the blade tip three-dimensional heat transfer characteristics. The first stage of GE-E3 high-pressure turbine has 46 guide vanes and 76 rotor blades, and the ratio of the vane to the blade is simplified to 38:76 to compromise the computational resources and accuracy. Namely, each computational domain comprises of one guide vane passage and two rotor blade passages. The investigations are conducted at three different tip gaps of 1.0, 1.5 and 2.0 per cent of the average blade span.

The results show that the overall discrepancy of the heat transfer coefficient between steady results and unsteady time-averaged results is quite small, but the dramatic growth of the instantaneous heat transfer coefficient along the pressure side is in excess of 20 per cent. The change of the aerothermal performance is mainly driven by turbulence-level fluctuations of the unsteady flow field within gap regions. In addition, the gap size expansion has a marginal impact on the variation ratio of tip unsteady aerothermal performances, even though it has a huge influence on the leakage flow state within the tip region.

This paper emphasizes the change ratio of unsteady instantaneous heat transfer characteristics and detailed the mechanism of blade tip unsteady heat transfer coefficient fluctuations, which provide some guidance for the future blade tip design and optimization.

This study explores the applicability of Anderson's (1999) code of the street framework to an Asian context by examining the relationship between residents' perceptions of police ineffectiveness, nationality, and street codes in foreigner-concentrated areas in South Korea.

The authors used survey data from 1,865 residents of diverse nationalities living in 20 foreigner-concentrated areas in South Korea. Mixed-effects ordinary least squares (OLS) regression and moderation analysis were used to examine (1) the association between residents' perceptions of police ineffectiveness and their street codes and (2) how this association varies across nationality groups.

The study findings overall indicated that higher resident perceptions of police as ineffective tended to correspond with greater levels of street codes. However, the interaction analysis results found that this relationship was conditioned by nationality. Specifically, perceptions of police ineffectiveness were associated with greater levels of street codes among foreign residents, particularly Korean-Chinese residents, whereas this was not the case among Korean residents.

The relationship between perceptions of the police and street codes described by Anderson (1999) has primarily been examined in the context of the U.S. To the best of the authors' knowledge, this study represents the first attempt to explore the link between residents' perceptions of the police and street codes by different nationality groups within an Asian setting.

This study develops a structural model to examine the relationships among subjective perception of health, subjective perception of economic and social support, the perceived freedom in leisure, leisure satisfaction, and the well-being of elders. The subject of this study is the elderly who participated in leisure activities at Evergreen Academy in Kaohsiung City. Convenience sampling and quota sampling are adopted. 1,200 self-administered questionnaires are distributed, and 535 are valid, with a response rate of 45%. The results of this study show that subjective perception of health will positively affect perceived freedom in leisure; subjective perception of economics will positively affect perceived freedom in leisure and well-being; social support will positively affect perceived freedom in leisure, leisure satisfaction, and well-being; perceived freedom in leisure will positively affect leisure satisfaction and well-being; leisure satisfaction will positively affect well-being. There are significant differences in the subjective perception of economic and social support between male and female elders. There are significant differences in the subjective perception of economic, leisure satisfaction, and well-being among those with different education levels.

The purpose of this paper is to estimate an individual’s probability of preservation of the night view of Han-River bridge tax using the contingent valuation method (CVM) and to present the effects of 4Es on experience economy theory.

The on-site survey was conducted in the 11 district Han-River parks: Gwangnaru, Jamsil, Ttukseom, Jamwon, Banpo, Yeechon, Yeouido, Mangwon, Nanji, Ganseo and Yanghwa district, including 24 bridges such as Banpo, Olympic bridge during 8-9 pm around the lighting and 9-10 pm peak time of lighting.

Truncated mean willingness-to-pay indicates that the economic value of the night view of Han-River bridge is 49,575 won (about USA $50) per household, which implies the significance of the preservation value of the night view.

This study sets a hypothetical market, and there are limitations on hypothetical bias of the dichotomous choice CVM. For the future study, a survey with a specific real payment vehicle in an attempt to reduce hypothetical bias can be a tool for the prevention of the overestimation.

Through the study, Seoul city has to invest aggressively on the night view landscape business of Han-River bridge, which can become a landmark and has lots of attraction for tourists. As this study’s core aim was to justify the economic value of the night view of the Han-River bridges, the estimated amount strongly supports the lighting business of the Han-River bridge.

The results of this research may help policy-makers of Han-River to establish practical decisions as to whether improving and preserving the Han-River’s night view lighting business are worth the value.

The purpose of this paper is to investigate how we can understand social media interactions better by explicating the process of social capital formation on Facebook from a reciprocity perspective.

This study observed users who got tagged on Facebook by his/her friends and how s/he responded to that tagging activity. In total, 4,666 posts and 418,580 comments from The New York Times Facebook page were collected for the observation.

A majority (77.87 percent) of users who were tagged by their friends showed reactions to their tagging. In detail, 33.63, 44.20, and 0.04 percent of users responded by comments, “Likes”, and “Shares”, respectively. In total, 90.11 percent of the comments and 98.58 percent of the “Likes” were expressed on a comment or sub-comment, and only 9.89 percent of the comments and 1.42 percent of the “Likes” were expressed on a post. This indicates that a high percentage of users respond to their tagging notification, and they prefer dialogic responses to non-dialogic responses.

Previous studies have focused on photo tagging activity in social media, but user tagging activity had not been studied enough. This study examines the effects of Facebook tagging activity from a reciprocal perspective.

A vast proportion of global megaprojects have not performed up to the expectations of their stakeholders. A failed megaproject has the potential even to derail the economy of a country where it was implemented. Stakeholders must, therefore, ensure that they do not invest in megaprojects that are bound to fail. But, how can stakeholders consistently identify such megaprojects? This paper develops a framework for a metric that can help stakeholders measure the readiness of a megaproject.

A comprehensive literature review identified 19 critical success factors of megaprojects. These success factors were integrated into a fuzzy-based model to develop the megaproject readiness metric. An assessment team studied the levels of presence and importance of these success factors in a candidate megaproject to derive its readiness.

The readiness-based model provides stakeholders valuable insights into the strong and weak areas of a megaproject. It can help stakeholders prioritize and systematically eliminate the identified weaknesses and improve megaproject readiness. While the model was tested on a metro rail megaproject, it can be used on any megaproject across domains.

This paper adopts the concept of readiness for the domain of megaprojects. Besides the readiness measurement framework, a vital contribution of this research is its application to a real-life case. Future research can include more granular success factors to improve the estimate of megaproject readiness.

The purpose of this paper is to investigate the dynamic process and the meaning of symbolic consumption according to the three symbolic needs (i.e. status needs, social needs, status and social needs) to understand how symbolic messages are conveyed when consumers choose a brand.

This paper develops three dynamic models, categorized according to the consumers’ needs. The conceptual framework consists of the six constructs: collectivism/individualism, brand reputation, self-congruence, brand affect, brand identification and brand loyalty. Twelve hypotheses were developed and tested. Data were collected from consumers who had experienced well-known global chain restaurant brands. The three models were tested using confirmatory factor analysis and structural equation modelling.

Findings highlight the important mediating role of brand affect in symbolic consumption, which previously has not been revealed empirically. Moreover, it is found that self-congruence does not mediate the relationship between brand reputation, collectivism/individualism and brand affect, despite its prominence in previous symbolic consumption studies. In the status and social needs models, brand reputation mediates between collectivism/individualism and self-congruence, brand identification, brand affect and brand loyalty.

This is the first empirical paper to investigate symbolic consumption in the context of three types of models, according to symbolic needs, in the context of restaurant consumption. The study also identifies the major components of the consumer’s symbolic needs based on the attributes of symbolic consumption. Moreover, this study reveals that when both social needs and status needs are mixed, a hierarchy exists between consumers’ symbolic needs. Finally, the study makes an important contribution to the literature by applying the concept of brand affect to symbolic consumption research and exploring the relationships between the external motivational factors and the internal elements of symbolic consumption.
