International trade of GMO-related agricultural products

This paper examines the international trade of a variety of genetically modified (GM) food products over a 27-year period (1984–2011) with data from the United Nations using the tools of social network analysis. The results indicate that each of the different crops have a distinctive pattern of trade that has changed over time due to a number of different factors. Also, trade in agricultural commodities became more diversified over time, dominated less by the United States and other nations central in the trade networks and trade in the individual GM crops was stable over time. Countries maintained their trading partners for specific crops, despite the adoption of the genetically modified varieties. The economic implications of these results are discussed for specific countries.     

Audit Firm Attributes and Auditor Litigation Risk

This study examines the association between auditors' litigation risk and audit firm attributes. Using professional liability insurance premiums as a proxy for auditors' litigation risk, we present evidence that the risk is lower in audit firms having: (1) separate non-audit and audit divisions; (2) a higher proportion of partners; and (3) a higher annual growth in number of CPAs employed. Additionally, we find that the risk is higher in audit firms having: (1) operating losses; and (2) high revenue growth. Our results are consistent with the idea that audit firms' financial condition and organizational structure affect their independence/ expertise, and, in turn, their litigation risk. Our results are broadly supportive of the PCAOB's (2015) and US Department of Treasury's (2008) views that investors, audit committees, management, and other regulators could benefit from having access to financial and organizational information about audit firms.     

The effect of mandatory auditor assignment and non-audit service on audit fees: Evidence from Korea

In Korea, regulators could assign auditors to firms. We investigate the relationship among audit fees, mandatory auditor assignment, and the joint provision of non-audit and auditor services in Korea. We find that assigned auditors charge significantly higher audit fees than freely selected auditors. We also find that the joint provision of non-audit and audit services does intensify the relation between auditor assignment and audit fees. Combined with the results of other studies that have shown that firms audited by assigned auditors report smaller amounts of discretionary accruals than firms audited by freely selected auditors, our results suggest the possibility that mandatory auditor assignment may improve auditor independence.     

Open data in Nepal: a webometric network analysis

This study examines the current open data trends in Nepal based on the webometric analysis method by using search engines to trawl through websites and obtain data. The results indicate that various national and international nonprofit organizations, public sector organizations, educational institutions , and a few commercial organizations were the initial actors fostering open data in Nepal. Therefore, these organizations were analyzed in terms of their networking patterns and the extent to which they are exposed internationally in cyberspace by using Webometric Analyst 2.0. Inter-linkage analysis, co-mention analysis, and link impact analyses were conducted to explore the networking behavior in the World Wide Web. The results revealed that international organizations (IOs) were strongly interlinked. Nongovernmental organizations (NGOs), government organizations (GOs), and IOs were interlinked, but weakly. In terms of the co-mention network analysis, IOs with IOs were more significant than NGOs with NGOs, GOs, or business organizations because IOs had been working actively for many years, their web presence was high, and they worked in other fields, including open data. A link impact analysis was also conducted using its indicators of seed sites linked to external websites in terms of the estimated number of top-level domains and country-code top-level domains.     

Adaptive conjoint analysis for the vitalisation of angel investments by entrepreneurs

In order to promote angel investments, attracting those who have entrepreneurial experience is necessary because their capital, unique managing experience, and business insight are highly beneficial to the performance of the investment. This can be accomplished by providing a preferred investment environment for potential angels who have entrepreneurial backgrounds. In this paper, we use an adaptive conjoint analysis to identify preferred investment environments represented as a combination of support policies for business angels who have entrepreneurial experience in Korea. Of particular interest is a preference for angel insurance. This insurance is newly proposed based on prospect theory, which explains that people tend to be more sensitive to a loss than to a gain. The value of the angel insurance is compared to those of tax policies and matching funds for business angels. The empirical results are expected to contribute to promoting angel investments by attracting entrepreneurs to become business angels.     

Application of social media analytics in tourism crisis communication

Given the newly established communication environment of social media and highly unpredictable crisis situations, this study questioned how tourists facing an unexpected crisis situation use social media to communicate and search for information. To this end, this study developed a multi-phased social media analytic framework (data crawling, data processing and text mining, social network analysis, semantic network analysis, and network visualization) to assess the structure of information exchanges between the members of a tourism organization’s social network community and identified influential actors and information content within the social network. This study’s findings suggest genuine ways of relating with and utilizing opinion leaders and influencers in social media marketing communication as well as crisis communication. The authors expect this proposed methodological framework of social media analytics to help other scholars scientifically identify and implement the proper methodologies for utilizing social media data.     

YouTubers’ networking activities during the 2016 South Korea earthquake

While YouTube has become an important social networking platform for risk and crisis communications, research into its role and use during environmental disasters has not been conducted. The present study investigates how Korean YouTubers reacted during the 2016 Gyeongju earthquakes. Two kinds of data were collected from the most popular YouTube clips on the earthquake (from AfreecaTV and YonHap news): the most frequently used words in the replies to the comments and the networked forums among YouTubers. Findings suggest that YouTube has become a channel for quickly increasing public awareness of crises and for promoting safety strategies. InDegree Centralization is higher in professional videos. Hierarchy measure’s value is one, which means the reply-to network is not two-way. There is sparse close-knittedness in amateur videos. Community clusters emerge in amateur videos over time. The results also reveal that YouTubers on AfreecaTV are more likely to express emotional opinions than their counterparts on YonHap news are.     

Anchored putter ban: An examination of whether anchored putting impacts career success and putting performance

The Professional Golfers' Association (PGA) Tour ban on anchored putting (Rule 14‐1b) took effect on January 1, 2016. The ban remains controversial because the governance decision appears to have been made without adequate empirical evidence. Accordingly, to investigate the efficacy of the ban, the impact of using anchored putters on PGA golfers' career success and putting performance was examined. PGA golfers ranked in the top 125 were studied from 2009 to 2015. The analysis revealed an anchored putter offered no unfair advantage with regard to improving players' career success or putting performance when compared with standard putter usage by PGA golfers.     

Personalized goal-based investing via multi-stage stochastic goal programming

In this paper, we propose a goal-based investment model that is suitable for personalized wealth management. The model only requires a few intuitive inputs such as size of wealth, investment amount, and consumption goals from individual investors. In particular, a priority level can be assigned to each consumption goal and the model provides a holistic solution based on a sequential approach starting with the highest priority. This allows strict prioritization by maximizing the probability of achieving higher priority goals that are not affected by goals with lower priorities. Furthermore, the proposed model is formulated as a linear program that efficiently finds the optimal financial plan. With its simplicity, flexibility, and computational efficiency, the proposed goal-based investment model provides a new framework for automated investment management services.     

Towards Assessing the Knowledge Gap in Medical Tourism

The medical tourism industry is a fast growing global niche market that generated $20 billion in income for destinations around the world. This study suggests and tests a mechanism to assess the medical tourism providers’ perceptions about the tourists’ perceived important product attributes when selecting a medical tourism destination. The results indicate that the various medical tourism providers groups do not vary in their perceptions regarding 24 important attributes of the medical tourism product and that they all agree that tourists perceive the medical variables to be more important than the tourism related variables. Using the Korean market for data collection, the study’s additional contribution is providing insights for Korean government agencies, operators of medical tourism hospitals, policymakers, and marketers.
