Recently, the role of consumers in firms' innovation processes has increased. Prior literature asserts that qualitative aspects of consumers serve as crucial factors shaping the even competitiveness of a specific industry. This study focuses on measuring home demand conditions that enhance local firms' innovation.

The present study describes the development of a 12-item measure to assess consumer sophistication in the food industry. The items assess the general knowledge, experience, skills and abilities needed to purchase a specific food category. A second-order construct with three distinct first-order constructs emerged, which were termed opinion formulation, sensitivity and exposure with variety. The reliability and validity of the scale were assessed with pilot survey data using exploratory and confirmatory factor analyses. The developed measure was tested to investigate its effect on individuals' grocery buying behaviors using grocery receipt panel data from 723 consumers.

The results indicate that consumer sophistication has a positive effect on new and the variety of grocery purchases. The more sophisticated a consumer is, the more they buy new and a variety of products. The newly developed consumer sophistication measure has a variety of potential applications to predict consumers' variety-seeking and new product purchase behavior.

This study is the first to develop a measure for assessing demand quality, namely, consumer sophistication of a specific food product. This approach may offer insights to practitioners regarding the relevant consumer sophistication levels to target when launching a new product or service in the food industry.

The purpose of this paper is to investigate the effect of formulation categories (parent brand and extension product) and research and development (R&D) cooperation types on electronic word-of-mouth (eWOM) volume for extension products.

This study uses data from 109 extension products in the Korean dessert market whose formulations were changed between 1 February 2014 and 19 February 2019. The formulation categories and R&D cooperation types are transformed into dummy variables to conduct a linear regression.

The formulation categories and R&D cooperation types play key roles in proliferating eWOM for formulation change products. The most effective way to proliferate eWOM is through product extension by changing the formulation of ice cream, beverage and snack category products. Furthermore, vertical R&D cooperation positively affects the proliferation of products' eWOM.

These findings contribute to increasing the chance of successful food product development by providing information on the formulation changes that are effective at inducing consumers' interest.

A mobile office can be defined as software and hardware that support business work and that are accessible via smartphones. Organizations are adopting or trying to adopt the mobile office as their communication and business tool, in order to support or to change their current work environments. The purpose of this paper is to focus on the impact of outsourcing strategy on mobile office performance based on the FORT model and the MoBiS-Q to measure the performance of the outsourced mobile office.

This study focuses on the impact of outsourcing strategy on mobile office performance based on the FORT model and the MoBiS-Q to measure the performance of the outsourced mobile office.

In the results, the perceived usability and the perceived impact of the mobile office on the productivity can be higher with the Alliance outsourcing relationship type. The outsourcing of the mobile office would follow the similar process of other IT outsourcing strategies. But the device fittingness was far from the expectation.

Firms/organizations should consider a more concrete step-by-step approach to strategic outsourcing relationships with the high-skilled expert groups and that the device fittingness may not be a proper factor to measure the performance of the outsourced mobile office.

IT managers who plan or now try to adopt the mobile office into their organizations should focus on developing proper applications and software; however, they do not need to care about device or H/W issues, including employees ' skills at using the devices or the device fittingness for the planned mobile office.

This study is one of the first academic studies to analyze the impact of outsourcing strategy of the mobile office on organization performance.

The purpose of this paper is to understand music sharing behaviour on social networking services (SNS). This study suggests and examines a research model which focuses on the influences of user motivations, such as self‐expression, ingratiation, altruism, and interactivity, on music sharing behaviour in SNS through social motivation factors.

Data were collected from 153 Korean SNS (i.e. Cyworld, Naver Blog, Daum Blog, and Tistory) users, who have experience in purchasing music and legally sharing it on SNS. The partial least squares method was used to analyse the measurement and structural models.

The study shows that interactivity, perceived ease of use, self‐expression, social presence, and social identity are significant positive predictors of music sharing intention on SNS.

This research is significant in light of recent interest in user activities in SNS. Better understanding of the music sharing behaviour on SNS can be prompted by reflecting cultural differences in selecting the SNS for validation with a larger sample size.

The findings emphasise the importance of providing users with interactive, self‐expressive, and easily manageable services in order to increase their intention to share music through SNS. Service providers need to focus on improving the user experience of the systems.

SNS based online music services have been increasing and are a new business model of music content distribution. However no academic research has examined music related services on SNS. This study is the first empirical study analysing music sharing behaviour on SNS.

The purpose of this research is to examine the effects of interface consistency on the learning performance of skilled and novice computer users who are studying with web‐based e‐learning systems.

A literature review was conducted, and an experiment was set up to collect data on learning performance with respect to interface consistency and e‐learning systems. Statistical methods were applied.

Skilled students made more errors than novices when using a physically inconsistent e‐learning system. The learning satisfaction level of those skilled with computers was lower than that of novices using such a system. Conceptually consistent systems facilitated skilled students' learning satisfaction. Communicationally consistent systems closed the achievement gap within the novice student group. However, the effect of communicational consistency on skilled students was contradictory.

Implications include suggestions for designing web‐based interfaces of e‐learning systems and library web sites.

The purpose of this paper is to: empirically validate a modified unified theory of acceptance and use of technology (UTAUT) model by adding an “e‐learning motivation” construct in the South American context; try to determine the role of e‐learning motivation in the use and adoption of e‐learning systems and conversely the effect of technology on students' e‐learning motivation; and to test region and gender as moderators in the model.

A survey method was used to collect data from 47 schools located at different regions: the coast, Andes, and jungle of Peru. The partial least square technique was used for data analysis.

It was found that “e‐learning motivation” and “social influence” had a positive influence on behavioural intention, while “facilitating condition” had no effect on e‐learning portal use. Furthermore, use behaviour had a positive influence on e‐learning motivation. Also found was the moderating role of “region”.

The analysis is carried out in a single country, thus, caution should be taken in generalisation of the results.

The findings will help policy makers and practitioners in developing countries to better understand students' e‐learning motivation.

By adopting the UTAUT model, a new construct of “e‐learning motivation” is added, and applied to the South American context.

This study aims to address how the social structure of the hospitality management field has evolved from 1960 to 2016.

The informal social structure of the hospitality management literature was analyzed by collecting authorship data from seven hospitality management journals. Co-authorship analyses via network analysis were conducted.

According to the findings, throughout the history of hospitality management, international collaboration levels are relatively low. Based on social network analysis, the research community is only loosely connected, and the network of the community does not fit with the small-world network theory. Additional findings indicate that researchers in the hospitality management literature are ranked via degree centrality, closeness centrality and betweenness centrality. Cliques, which contain at least five researchers, and core researchers are identified.

This study helps both scholars and practitioners improve the informal structure of the field. Scholars must generate strong ties to strengthen cross-fertilization in the field; hence, they collaborate with authors who have strong positions in the field. Specifically, this provides a useful performance analysis. To the extent that institutions and individuals are rewarded for publications, this study demonstrates the performance and connectivity of several key researchers in the field. This finding could be interesting to (post)graduate students. Hospitality managers looking for advisors and consultants could benefit from the findings. Additionally, these are beneficial for journal editors, junior researchers and agencies/institutions.

As one of the first study in the field, this research examines the informal social structure of hospitality management literature in seven journals.

The purpose of this paper is to advance our understanding of the roles that service employees’ responses to high job demands play in service innovation, by examining the effects that service employees’ motivational orientation in self-regulation (regulatory focus) and their emotional labour strategy have on their creativity.

By integrating regulatory focus theory and emotion regulation theory, the authors developed a theoretical model to propose the links between promotion and prevention regulatory foci, different emotional labour strategies and frontline employee creativity. The research hypotheses were tested using hierarchical linear model based on data collected from 304 frontline employees and 72 supervisors in 51 restaurants.

The results showed that promotion focus was positively related to frontline employee creativity while prevention focus was negatively related to it. In addition, both emotional labour strategies (deep acting and surface acting) mediated the effect of promotion focus on frontline employee creativity. Surface acting mediated the effect of prevention focus on frontline employee creativity.

This is the first research conducted to explain, from a self-regulatory perspective, the influence that is exerted on service employees’ service innovation by their responses to high job demands. The findings identify the effects that service employees’ promotion focus or prevention focus in self-regulation have on their creativity, and the data unravel the role of emotional labour strategy as the mediating mechanism that explains the influence of regulatory focus on service employee creativity. On the basis of the findings, managerial directions are offered with regard to managing service employees’ regulatory focus and emotional labour, with a view to enhancing the creativity and innovation within a service organisation.
