Exploring the comparative importance of online hotel reviews’ heuristic attributes in review helpfulness: a conjoint analysis approach

Online travel reviews have become increasingly important as a result of the intangible and heterogeneous characteristics of the tourism industry as well as the recent diffusion of social media. This exploratory case study intends to examine the comparative importance of the six heuristic attributes (reviewer location, reviewer level, reviewer helpful vote, review rating, review length, and review photo) with respect to review helpfulness in the online hotel review context. Moreover, the salience of the individual levels within each review attribute and the importance of the attributes in positive and negative review-rating groups are compared. In total, 1,158 reviews of a hotel on TripAdvisor were collected and analyzed through conjoint analyses. This study found that the review rating and reviewer helpful vote attributes are the two most important factors. Finally, three major propositions are suggested based on findings of the study, and several theoretical and managerial implications are discussed.     

Introducing the paradox theory in logistics and SCM research – examples from a global sourcing context

The purpose of this paper is to introduce and explore the use of paradox theory in a logistics and SCM research context. Although logistics and SCM scholars as well as practitioners have been aware about the existence of paradoxes, they have so far lacked a more formal theoretical framework for further identification and classification of these. Framed in the four general paradox classes of learning, belonging, organising and performing, the paper outlines paradoxes inherent in the global sourcing practices of two case companies. The findings demonstrate the paradox theory to be a useful tool for a systematic illumination and classification of paradoxes valuable for practitioners, researchers as well as teachers in the domain of logistics and SCM. The paradox theory may also help to identify and emphasise inconsistencies among different research fields. This is particularly valuable for research areas built upon multiple research disciplines such as global sourcing. In conclusion, the paper suggests that the paradox theory offers a new lens through which an organisation could be better explored, described and understood.     

An examination of market efficiency around hurricanes

Hurricane Andrew produced more than $21.5 billion in property damage in Florida and Louisiana. Hurricane Hugo caused about $7 billion in damage in North and South Carolina. Although both hurricanes were large, the magnitudes of their destruction and the geographic concentrations of their paths were markedly different. This study finds that Hugo and Andrew produced substantially different market reactions on property and casualty (P&C) firms. The industry was generally unaffected by Hugo, regardless of whether or not firms had exposure in the Carolinas. Andrew, on the other hand, generated a significant negative impact on firms with exposure in Florida or Louisiana. Other firms were not effected by Andrew. These observations indicate that the market demonstrated an ability to discriminate by the magnitude of hurricane and by P&C firms based on their degree of loss exposure.     

GARCH models,tail indexes and error distributions: An empirical investigation

We perform a large simulation study to examine the extent to which various generalized autoregressive conditional heteroskedasticity (GARCH) models capture extreme events in stock market returns. We estimate Hill's tail indexes for individual S&P 500 stock market returns and compare these to the tail indexes produced by simulating GARCH models. Our results suggest that actual and simulated values differ greatly for GARCH models with normal conditional distributions, which underestimate the tail risk. By contrast, the GARCH models with Student's t conditional distributions capture the tail shape more accurately, with GARCH and GJR-GARCH being the top performers.     

The coordination roles of relief organisations in humanitarian logistics

The number of organisations involved in relief work in general and humanitarian logistics specifically is large and increasing, creating new complexity. In this paper we analyse different types of coordination and roles in two case studies of the humanitarian cluster system based on its initial development and the Kenyan Post-election crisis. The different and unclear roles of the organisations create significant problems before and after cluster activation and deactivation. Individual organisations take on many roles in the cluster system and beyond it in terms of coordination. The clarity of the roles affects the need for and ease of coordination. We suggest a simple basic categorisation of roles as a starting point for developing this concept in the field of humanitarian logistics and connect this to coordination.     

管理者交易的市场择时能力对市场有效性的影响

管理者卖出和买入公告对股票市场具有一定的影响,以管理者卖出交易和买入交易为公告样本进行实证分析,检验公告当日及给定事件期超额收益的显著性.结果显示:卖出公告样本反对半强式有效假说,管理人能够“卖高”,获得超额收益；而买入公告样本支持半强式有效假说,管理者不能够“买低”,在公告日和事件期都不能获得超额收益.

The Transition to E-Commerce: A Case Study of a Rural-Based Travel Agency

ABSTRACT

When the Internet started to establish itself in the corporate world, some observers foresaw a diminishing role for, if not the end to, many intermediary functions. Consequently it has been argued that suppliers will need to use the Internet and related technologies to cut costs and establish closer links with consumers by bypassing organizations that currently play an intermediary role in the traditional transaction system. The objective of this case study is to enhance the understanding of the process of transition from a traditional business model to an e-commerce model. It focuses on a very small business that has successfully navigated the transition to e-commerce.
