菲涅耳非相干全息术3D全息成像探讨

全息成像提供了一种从单一观察点捕捉具有完整三维信息画面的可靠、快捷的方法。本文回顾了近期提出的单通道菲涅耳数字全息光学系统,该系统能获得由非相干光照射的三维实物体的全息图。在这一静态全息技术中,由三维物体反射或发射光,在通过空间光调制器（SLM）后,用数码相机记录。SLM被用作单通道非相干干涉仪的分束器,使来自物体上各点的球面波被分成两束具有不同曲率半径的球面波。所有球面波干涉结果的非相干总和,即可生成被观测物体的三维菲涅耳全息图。在计算机中可再现该全息图,使其三维特征得以呈现。

Barcelona seen through the eyes of TripAdvisor: actors,typologies and components of destination image in social media platforms

Recent literature has emphasized the emerging role of social media in generating a destination image. Even so, there is still no clear definition of the main actors, typologies and components prevailing in these environments or the possible differences between diverse social platforms. Specific analysis and comparison of the Barcelona TripAdvisor Forum and a traditional Destination Management Organization (DMO) website showed that actors, typologies and components are platform specific and have both similarities and differences with other sources, including DMO websites and other social media platforms.     

Methodology Influences on Destination Image: The Case of Michigan

In the last 30 years, destination image has emerged as a dominant theme in tourism research studies for both tourism industry practitioners and academic researchers. The results of these studies are intended for destination management purposes and thus are of utmost importance for destination success. Various factors are postulated and demonstrated to influence destination image; however, there is a lack of focus on the methodologies employed when evaluating the image of a destination. The purpose of this study is to investigate the potential impact of some methodological tools used when measuring destination image. A large scale and longitudinal market survey dataset of the Michigan Regional Travel Market Survey was analysed for the purpose of this study. A wide range of methodological factors from data gathering modes to analytical techniques utilised were found to influence the revealed image of the study destination, Michigan. Detailed discussion of potential bias factors and potential research directions are provided.     

The 7th Asia-Pacific CHRIE Conference

Despite the increase in use of user-generated electronic content as an information source by tourists, its influence in destination image formation is not yet fully understood. This research aimed to explore the communicated destination image held by tourists to Zanzibar Island (Tanzania) by utilizing communications in Lonely Planet. Content analysis of 214 posts using TextSTAT yielded 13 destination attributes. Comparatively, functional attributes were dominant in potential tourists whereas post-travel image perception was dominated by psychological attributes. Those who have visited tended to have a positive image of the island compared with those who are planning to visit the island. The results necessitate the differential use of the functional- and psychological-based information in communicating with tourists at different information-search stages. Studies to capture communications in another language are recommended as well as the employment of methodologies that might reveal hidden images held by tourists.     

Narratives of Negotiation and Transformation: Women's Experiences within a Mixed-Gendered Gym

ABSTRACT

Those within the fitness industry claim that gyms provide accessible space for women (of certain economic status) to engage in activities that will increase their health. As such, gyms are marketed as safe, inclusive, and empowering spaces. Yet when viewing gym spaces through a feminist-informed lens, it becomes clear that gyms are not always innocuous spaces. They often reflect and perpetuate gendered power relations and highly prescribed cultural expectations for femininity around women's bodies, appearances, strength, and abilities. This narrative inquiry sought to illuminate women's gendered experiences within a for-profit mixed-gendered gym space. Through the use of unstructured life story interviews, this research highlights the dominant gendered expectations that women perceived within the gym and how these expectations influence women's gym use. The narratives also exposed several ways that gyms can be changed in order to facilitate more positive gym experiences for women.     

City Image and Perceived Tourism Impact: Evidence from Port Louis,Mauritius

Research suggests that the images residents hold about their community influence the political support for tourism. Yet, few researchers have investigated the image that local residents have of their own area. Borrowing from the existing literature on place image and residents' perceptions of tourism impacts, a theoretical model incorporating these two lines of research is developed and tested using data collected from residents of the city of Port Louis, Mauritius. It proposes four city image attributes as the independent constructs influencing residents' perceptions toward the overall impact of tourism development. These include social attributes, transport attributes, government services attributes, and shopping attributes. Overall impact of tourism development is considered to be a determinant of the level of support for the industry. Results of the structural equation modeling analysis indicate that residents' perceived levels of shopping attributes, transport attributes, and social attributes of the city influence their level of support for the tourism industry. The hypothesis relating transport attributes to overall impacts of tourism was not supported. The study provides some important considerations for local planners attempting to make tourism more supportive in the city.     

Analyzing Destination Images: A Perceptual Charting Approach

Abstract

Heterogeneity of perceptions is a neglected issue in market segmentation studies. Only recently parametric approaches toward modeling segmented perception-preference structures such as combined MDS and Latent Class procedures have been introduced. A completely different nonparametric method is based on topology-sensitive vector quantization (VQ) for consumers-by-brands-by-attributes data. It maps the segment-specific perceptual structures into bar charts with multiple brand positions exhibiting perceptual distinctiveness or similarity. A brief introduction into the VQ methodology is followed by a sample study on three urban destinations competing on the world travel markets. City images serve as the underlying behavioral constructs. Preferential data are based on respondents' comes-closest-to-ideal-city judgments and incorporated into the perceptual positions of city profiles. Perceptual charting works on two levels of aggregation named prototypes and perceptual sub-structures. The results demonstrate how this method prevents the analyst from drawing erroneous conclusions due to uncontrolled aggregation.
