Linking emotion and place on Twitter at Disneyland

ABSTRACT

This study suggests a research framework for social network analytics and demonstrates the process of integrating data and applying methodologies to understand visitor experiences at a destination. We applied both social media analytics and geographic information system (GIS) analysis to identify major topics and emotional expressions in a social network. A total of 56,418 tweets sent from Disneyland in California was used for analysis. The results identified three hot spots in the park where significantly pleasant tweets were posted. How to apply the research framework is discussed, and suggestions to researchers and marketers are given.     

R&D project team climate and team performance in Korea: A multidimensional approach

This study examined the relationship between R&D team climate and team performance in a developing context, Korea. Given the fragmented results of existing studies in advanced countries, which explored largely the effects of individual dimensions of team climate on team performance, this study focused on the interaction effects among multiple dimensions of team climate. The interaction effects can produce seemingly contradictory or paradoxical bivariate associations between each climate dimension and team performance. Both bivariate and multivariate analyses, using data from 80 R&D project teams in both government-sponsored research institutes and private R&D centres in Korea, revealed the following results. 1. Four dimensions of R&D team climate—autonomy, cohesiveness, change orientation, work pressure—were not positively associated with team performance. Rather, autonomy was found to have a significant negative relationship. 2. Interaction effects of each team climate dimension were partially borne out. When the change orientation or work pressure of a team was high, autonomy had a positive impact on team performance. Otherwise, autonomous team climate deteriorated performance of the team. However, interaction effects between cohesiveness and change orientation or work pressure were not found significant. 3. There appeared three clusters of R&D teams with similar climate characteristics. Teams with high autonomy but a low change orientation exhibited a lower level of performance than the other two clusters—one with low autonomy but high change orientation and work pressure, and the other with a medium level of autonomy and change orientation. The results implied that a holistic team climate, as well as an individual aspect of climate, had a significant impact on team performance. A configuration approach considering interaction effects among various climate aspects would be beneficial for the development of high performing R&D teams.     

Predatory reputation in US airline markets

Despite its long history in antitrust policy, predation remains a poorly understood phenomenon. The main difficulty is in empirically identifying predatory intent. I propose a method for measuring the effect of reputation, whose significance would enable us to infer predatory intents. Maximum likelihood estimation using simulated annealing algorithm is conducted with a sample of US airline markets. The results provide some support for the presence of entrants learning and reputation effect. As an application, I discuss how the outcomes of my empirical model could help analyze such antitrust cases as the American Airlines Case.     

The Role of the Business Press in Creating and Disseminating Information around Earnings Announcements

This paper investigates the role of the business press in creating and disseminating information around earnings announcements by examining different motivations of trading volume. We find that press coverage is positively associated with trading activity motivated by differential interpretation and by differential belief revision, consistent with the press playing both an information creation and information dissemination role around earnings announcements. When we divide press coverage into full articles with additional editorial content and news flashes merely repeating verbatim of firm-disclosed press releases, we find that trading volume motivated by both differential interpretation and differential belief revision increases as coverage by full articles increases, and trading volume motivated by differential belief revision increases as coverage by news flashes increases. We also report that the differential interpretation effect of full articles is more pronounced when information users’ sophistication is high. Overall, we provide new evidence to the literature by showing that each type of press coverage plays an informational role in different motivations of trading activity.     

The Effects of the President’s Emergency Plan for AIDS Relief on the Economies and Domestic Politics of Focus Countries

President G.W. Bush’s Emergency Plan for AIDS Relief (PEPFAR) has been rated as one of the successful US aid interventions of recent decades. We investigate the impact of PEPFAR on economic development, democracy, and human rights by comparing focus countries that received PEPFAR with other countries that did not receive PEPFAR from 2003 to 2008. Moreover, we examine specific changes made within focus countries after the implementation of PEPFAR using Difference-in-Difference estimation. Our results show that PEPFAR did improve economic conditions in focus countries but had a limited impact on political conditions, that is, on democracy and human rights.     

Creating and Recreating Heritage in Singapore

The aim of this paper is to examine the extent to which public planning and policy have created a 'national' identity for Singapore since its independence in 1965, the importance of heritage to contemporary Singapore, and how heritage is marketed to Singaporeans and visitors. Over the last 30 years Singapore has striven to create itself as one of the most modern and successful of the ASEAN nations, but this may have been at the cost of its indigenous cultures and authentic heritage. Many of the craft industries common in the late 1970s and 1980s have been lost, and while the Singapore Tourism Board promotes Chinatown, Little India and Kampong Glam as 'pockets of individuality' in Singapore's multicultural society, souvenirs currently on sale were made in China, India, Malaysia and Indonesia. By contrast, the enduring image of 'Singapore Girl' for Singapore Airlines led to an entire souvenir culture and a batik clad 'Singapore Girl' Barbie Doll.     

利用产学联系的中小企业ERP引进策略

本文对引入公司资源管理计划系统的必要性进行了研究,并对中小型企业运用公司资源管理计划系统的关键因素进行了深入的分析。在此基础上,我们给出了支持中小企业实施公司资源管理计划系统和促进中小企业电子商务发展的相关计划和教育产业关系模型。公司资源管理计划系统的实施,首先需要对该系统进行系统化的评估,进而选择适合公司自身环境的资源管理计划系统。除一些关键因素外,许多环境因素对引入该计划体系起着很大的影响作用。环境因素主要包括公司资源管理计划系统的专家、顾问、开发者和信息系统管理者;另外还包括公司的筹资能力和组织内的信息化程度。     

Local institutional investors,information asymmetries,and equity returns

We examine the informational role of geographically proximate institutions in stock markets. We find that both the level of and change in local institutional ownership predict future stock returns, particularly for firms with high information asymmetry; in contrast, such predictive abilities are relatively weak for nonlocal institutional ownership. The local advantage is especially evident for local investment advisors, high local ownership institutions, and high local turnover institutions. We also find that the stocks that local institutional investors hold (trade) earn higher excess returns around future earnings announcements than those that nonlocal institutional investors hold (trade).     

Developing an index of online customer satisfaction

This paper integrates and applies the concept of ‘satisfaction’ from three fields: management information systems (MIS), marketing and e-commerce. E-customers are viewed as both computer users and customers and as a result researching customer satisfaction in e-commerce needs to integrate aspects of satisfaction from each of these fields. This study defines e-customer satisfaction and develops an index using a weighted sum model. The index is tested using a Korean sample. Analyses suggest an acceptable model and a generalisable set of measures from which managers and researchers evaluate online satisfaction and, especially, marketing strategies in financial services industries.
