Integrating uncertain user-generated demand data when locating facilities for disaster response commodity distribution

This paper presents a new facility location problem variant with application in disaster relief. The problem is unique in that both verified data and unverified user-generated data are available for consideration during decision making. The problem is motivated by the recent need of integrating unverified social data (e.g., Twitter posts) with data from more traditional sources, such as on-the-ground assessments and aerial flyovers, to make optimal decisions during disaster relief. Integrating social data can enable identifying larger numbers of needs in shorter amounts of time, but because the information is unverified, some of it may be inaccurate. This paper seeks to provide a “proof of concept” illustrating how the unverified social data may be exploited. To do so, a framework for incorporating uncertain user-generated data when locating Points of Distribution (PODs) for disaster relief is presented. Then, three decision strategies that differ in how the uncertain data is considered are defined. Finally, the framework and decision strategies are demonstrated via a small computational study to illustrate the benefits user-generated data may afford across a variety of disaster scenarios.

Characteristics of a Unique Market Segment

Modified grocery shopping and consumption behaviors have been recent outcomes of consumers' changing attitudes toward food and nutrition. This article identifies a unique segment important to grocery retailers- shoppers who purchase and consume greater varieties of fresh fruit. These consumers are shown to differ from other consumers in their food shopping and preparation attitudes, fruit and grocery expenditures, and their demographics. Opportunities for adapting fresh fruit product offerings, promotions, and services to this segment are explored.     

“It's nice to get a wee treat if you've had a bad week”: Consumer motivations in retail loyalty scheme points redemption

Research into loyalty schemes focuses primarily on business (strategy) rather than consumer perspectives. This paper investigates consumer motivations in retail loyalty scheme points redemption, through a qualitative study of participants in a major UK retail loyalty scheme. Academic research tends to neglect investigation of points redemption, despite its probable significance to consumers and certain value to businesses. The research identifies planned behavior towards redemption goals, plus interruptions by various circumstances and events. Self-gifting for reward and/or therapy purposes is common. Redemption activities have positive implications for consumer perceptions of the scheme and the retailer and appear to enhance future purchasing behavior. From these findings, this paper draws implications for theory and practice.     

TEM-4完形填空的考点效度分析

本文以TEM-4改革后至今的6年完形填空试题（2005-2010年）作为研究对象,从考点层次和考点因素的角度,分析和探讨TEM-4完形填空的考点效度及其对英语专业基础阶段教学的启示。分析结果表明改革后的TEM-4完形填空具有较高的考点效度,在考点层次上侧重对受试者句子和语篇层次的考查,而在考点因素方面意义因素占据了主导地位。从2005-2010年TEM-4完形填空的变化趋势来看,TEM-4完形填空正逐步将其考查重点更多地移向语篇层次和意义因素,这一变化将使它的考点效度进一步提高。

Joint modeling of effects of customer tier program on customer purchase duration and purchase amount

Nowadays, many supermarkets implement a customer tier program to increase their profits because it is expected to raise customers' willingness to purchase by setting thresholds. However, designing an appropriate program is difficult because each customer's heterogeneous purchase behavior is difficult to capture. Therefore, we simultaneously modeled purchase frequency and amount through a marked point process approach while considering program effects and customer characteristics. The results clarified that the points pressure effect was particularly strong among customers who originally visited the store infrequently and had not attained the threshold set up in the customer tier program many times in the past. In addition, we found that the three-tier customer tier program was superior to the two-tier program with respect to the operating income in supermarkets.
