Vacationers and the economic “double dip” in Europe

The subject of this study concerns individual vacationers' reactions to the global economic crisis. This crisis is lasting longer than expected, resulting in Europe in a “double dip”. Vacationers can use different strategies to cope with this crisis: from pruning (giving up the vacation) via cheese-slicing (economizing on vacation attributes) to non-economizing. Based on a theoretical framework, it was predicted that over time the pruning segment would become larger than the cheese-slicing segment. A longitudinal study in The Netherlands, covering 4 years, shows economic developments having a relatively minor effect on vacationers' holiday plans and intentions, with no increase in the size of the pruning segment. Six vacationer segments were found, three of which can be considered to be crisis-resistant. Each segment pursues different economizing strategies, with each requiring a customized marketing strategy. Five explanations are proposed for the relatively limited influence of the economic “double dip” on Dutch vacationers. Future research can be directed to comparing vacations with other consumer products, in order to explain the crisis-resistance of vacation planning during this economic crisis.     

Does offering an organic food menu help restaurants excel in competition? An examination of diners’ decision-making

This study aims to examine whether the presence of an organic food menu can positively influence diners’ decision-making. A 3 (restaurant segment: quick service vs. casual dining vs. fine dining) by 2 (price discrepancy between competing restaurants: small vs. large) scenario-based experiment was conducted with 405 U.S. consumers. MANCOVA results indicate that using organic ingredients offers a greater advantage for the quick-service segment regarding perceived food quality, attitudes towards the restaurant, and willingness to select, compared to casual and fine dining segments. The magnitude of a premium price of organic ingredients negatively influences such advantage in the process of consumers’ decision-making. When a large (vs. small) premium price is charged for using organic ingredients, customers’ preferences for the restaurant (over its rival) significantly drops to such an extent that customers are more willing to choose the competitor (i.e., rival restaurant with a conventional menu). Discussions and implications are further elaborated.     

The symmetric and asymmetric influences of destination attributes on overall visitor satisfaction

Visitors are impressed by specific destination attributes, which are sometimes the main motivating reasons for the travel selection or sometimes they are just one of the elements of a whole destination experience. This is because tourism and travel products are generally a combination of several different supplier offerings or they are a combination of the natural and artificial attributes of a destination that cannot be fully known before the experience of travel. Moreover, the importance and influence of these attributes on overall visitor satisfaction may differ considerably, depending on the market segments. In recent years, some studies have shown that the influences of destination attributes on overall visitor satisfaction are not symmetric in every case. For the purposes of this study, the symmetric and asymmetric influences of destination attributes are investigated for three major market segments of the Side-Manavgat area, Antalya, Turkey. The results show that the importance and influences of destination attributes may change according to the analysis technique employed and the market segment examined.     

A Conjoint/Logit Analysis of Consumers’ Responses to Genetically Modified Tofu in Taiwan

We use data collected from a consumer survey of face‐to‐face interviews to determine consumer demand for genetically modified (GM) tofu attributes in Taiwan. Conjoint analysis using logit models reveals that, on average, brand is the most important attribute in terms of influence on consumers’ preferences, followed by price, with GM content having the least influence. However, the analysis also reveals three distinct market segments for tofu. Apart from the largest segment (which reflects the average lack of concern about GM food), the remaining two segments are split according to their preference or antipathy towards GM tofu. This result suggests that GM labelling is helpful to Taiwanese tofu consumers.     

On the importance of matching strategic behavior and target market selection to business strategy in high-tech markets

Business strategy is fundamentally concerned with the actions required to create superior customer value in the firm’s target markets with the ultimate goal of achieving superior performance. Marketing theory suggests that two critical marketing activities required to achieve this end are: (1) the adoption of appropriate strategic behaviors (i.e., customer-oriented, competitor-oriented, technology-oriented) and (2) targeting of the appropriate market segments (i.e., innovators, early adopters, early majority, late majority, laggards). This study builds on prior research which demonstrates that the strategic behavior—firm performance relationship is contingent on the firm’s strategy by examining this relationship in high tech markets and by considering the incremental contribution of appropriate target market selection. Responses from 160 senior marketing managers in high-tech firms reveal strong support for our framework. Thus, this study provides useful guidance to executives and managers in high-tech firms regarding the steps that they should take to increase their probability of success.

预制节段拼装预应力混凝土箱梁胶接缝抗剪性能研究

由于节段间接缝的影响,导致预制节段预应力混凝土箱梁接缝处抗剪机理与连续整跨梁存在较大差异,在计算抗剪承载力时无法直接应用整跨梁抗剪计算公式。首先对节段拼装箱梁接缝处的抗剪机理进行分析,得到影响计算抗剪承载力的关键参数;其次在已有计算公式的基础上,考虑混凝土立方体抗压强度和接缝处键齿数等参数的影响,提出适用于这种抗剪承载力的计算公式;最后将提出的计算公式与试验数据对比,表明该计算公式中的参数物理意义明确,计算精度较高,为预制节段拼装预应力混凝土箱梁结构的设计及应用提供了一定理论基础。     

Mature consumers’ patronage motives and the importance of attributes regarding HMR based on the food-related lifestyles of the upper middle class

The objectives of this study are to explore the food-related lifestyle segments of the mature market, to identify its socio-demographic characteristics, and to investigate the differences in their attitudes toward Home Meal Replacement (HMR). A survey was conducted of adults 55 years of age and older living in Seoul, South Korea. Out of the 600 distributed questionnaires, 361 were retained for final analysis, which is a response rate of 60%. Cluster analysis identified five consumer segments. Significant differences were found among the five segments in terms of socio-demographic characteristics and attitudes toward HMR. This study shows operators of HMR the patronage motives and attributes that each segment values when considering HMR.     

莱商银行差异化经营案例

我国二元的信贷市场结构,决定了中小银行定位于中小企业很大程度上是一种被动选择。中小企业总体风险天然大于大型企业,中小银行如何实现中小企业的市场定位、持续良性的业务发展、行之有效的风险防控三者之间的有效契合,有必要进行研究探讨。莱商银行作为一家中小城市商业银行,经过多年摸索,逐步实现了被动选择基础上的主动适应和积极作为,走出了一条适合中小银行自身特点的、与国有商业银行和全国性股份制商业银行进行差异化竞争的发展路径,被业界称为"莱商现象"。本文以莱商银行为例,对其成长过程进行还原、再现和剖析,以期对中小银行的业务拓展和风险防控有所裨益。     

To cluster or not to cluster?: Understanding geographic clustering by restaurant segment

This study tested whether geographic clustering differs by restaurant segment due to the differences in consumers’ hedonic and utilitarian values by using Ripley’s K function and a Tobit model. This study found that higher priced restaurant segments have stronger clusters than lower priced restaurants, which implies that restaurants that focus on hedonic values tend to cluster more than utilitarian focused restaurants. However, the results differ depending on whether or not restaurants are located within a central business district (CBD). For example, quick service restaurants have stronger clusters than casual restaurants outside CBDs. Practical applications may apply to new restaurants that are attempting to open. Up-scale restaurants have the advantage of reducing research costs by locating near similar restaurants. Moreover, casual restaurants do benefit by clustering near existing ones under the condition that demand is not severely hurt by competition, while quick service restaurants benefit by diffusing from each other.
