Evaluating and Categorizing Cruise Lines by ship attributes: A Comparison Between Cruisers and Experts

Electronic Word-of-Mouth (eWOM) is an important information source used by consumers to make travel decisions. However, eWOM from travel experts and everyday travelers can be inconsistent, potentially leading to blurred product evaluations and market positioning. This paper examines this issue in the context of the cruise industry with the goal of identifying differences in the evaluation of cruise brands by cruise experts and consumers, as well as the product factors that influence these judgements. The research used a data-driven empirical approach and secondary data from a leading cruise review site consisting of scaled ratings across 9 ship attributes and 24 brands by more than 150,000 cruisers and 174 experts. Data analysis using the TOPSIS method and regression and multigroup models shows that experts and cruisers evaluate cruise brands differently and are influenced by different ship attributes when forming evaluations. For example, value-add attributes (e.g., service, enrichment activities, fitness/recreation) significantly influence overall evaluations for cruisers, while core attributes (e.g., cabin, dining, entertainment) significantly influence overall evaluations for experts. Discussion of the empirical results highlights these differences in cruiser vs. expert perceptions as revealed online, as well as the need to update traditional cruise industry categorization to optimize brand positioning and better align product-marketing strategies for effective target marketing.     

弹载SAR宽域成像的扫描参数设计

针对弹载条带合成孔径雷达(SAR)在末制导阶段由于波束覆盖范围窄和成像时间短,不易获 得所 要求的大面积图像的问题,提出了一种新的波束扫描方案,并根据导弹在末制导阶段的飞行 特点,结合子孔径处理方法,对波束扫描参数进行了理论分析和设计。仿真结果表明,与条 带SAR相比,该扫描SAR能有效地在较短的数据录取时间内获得大面积的SAR图像。     

Using Twitter Data for Cruise Tourism Marketing and Research

The need to understand how social media affect the hospitality and tourism field has increased. This paper discusses and demonstrates social media analytics using Twitter data referring to cruise travel. This research also includes an in-depth analysis of tweets by three types of user groups: commercial, news/blogs, and private. The results show that not only were words related to travel, destination, industry, and emotion most frequently used in composing tweets, but celebrities, professional bloggers, cruise lines, and travel agencies actually led major subgroups on cruise topics on Twitter. Based on such findings, this study provides feasible marketing strategies.

Economic impact of cruise activity: the case of Barcelona

ABSTRACT

This article shows the methodology and the main figures of the local and regional economic impact generated by cruise activity. This article is pioneering in combining different issues: estimating the impact of the cruise port activity, presenting these impacts disaggregated at a sectoral level, using a rigorous methodology and carrying out extensive fieldwork. It is demonstrated that all sectors, not just traditional tourism-related sectors, benefit from cruise tourism. In order to test and apply our methodology we focus the analysis on the Port of Barcelona, which has become the leading cruise port in the Mediterranean area.     

Word-of-mouth,buying, and sacrifice intentions for eco-cruises: Exploring the function of norm activation and value-attitude-behavior

Our theoretical framework was designed to explain passengers' decision-making process for environmentally responsible cruise products. Specifically, the goals of this study were to investigate passengers' decision formation by employing the Norm Activation Model (NAM), to extend it by integrating the value-attitude-behavior cognitive hierarchy, emotional process, and normative procedure, and to test the moderating impact of non-green alternatives' attractiveness in a cruise context. The measurement quality was found to be adequate. The prediction power of the proposed framework was superior to the original NAM. Findings from the structural model revealed that the hypothesized associations relating study variables within our proposed theoretical framework were generally supported; personal norm acted as significant mediators; and the role of personal norm and social norm in building intentions was salient. Additionally, the hypothesized moderating impact of alternatives' attractiveness in determining intentions was supported.     

Selecting a cruise port of call location using the fuzzy-AHP method: A case study in East Asia

Increasing income levels and greater leisure time give people the opportunity to pursue new types of tourism ventures. As one of the fastest growing areas in the leisure travel industry, the cruise industry is increasing rapidly. Due to the benefits that cruise tourism brings to each port of call and the hinterland, it is necessary to be able to analyze the factors that affect cruise lines' port selections. The main objective of this paper is to identify the main factors motivating cruise lines to select specific ports of call and to provide information to port operators that will enable them both to improve their management strategies and to attract more cruise ships, thereby contributing to the revenues of the port and regional economy.

In search of ‘a research front’ in cruise tourism studies

This article aims to provide a critical view of the global scientific production involved in cruise tourism study. Global references in this field were identified and emphasised for managing existing data to establish ‘bridges’ among researchers. Scientometric analysis was conducted on publications about cruise tourism in mainstream journals integrated into Web of Science. This methodology enabled us to identify current topics, relevant journals, authors, institutions, profitable countries, ‘visible’ and ‘invisible’ collaborative colleges and the research areas considered as the epicentre of the cruise tourism debate. A significant contribution of this work is the use of indicators at the three levels of scientometric complexity, i.e. scientific activity, impact and relational character.
