<p>  </p> <p>Food safety educators and specialists are committed to closing the food safety education gap among different actors in the supply chain, from farm to fork. To accomplish it, they have to understand the needs of the target population to disseminate information and develop interventions. This thesis is divided into three case studies to explore needs assessments (Ch. 1 and 2) and program evaluation (Ch. 3). The first needs assessment (Ch.1) was developed due to a recent multistate outbreak linked to dried wood ear mushrooms. This study evaluated YouTube video content on the preparation of different wood ear mushrooms dishes and investigated the food safety risk associated with the handling practices. Practices such as rehydration procedures were identified as key food safety risk factors that need future exploration. The second needs assessment (Ch.2) was developed due to the impact of small- and medium-sized farms on USA agriculture. This study aimed to understand consumers’ perceptions and expectations of produce from small- and medium-sized farms and their desire to pay a premium price for food safety information. The findings showed that consumers perceived the produce from these farms to be fresher and of higher quality. Also, they considered food safety as a minimum quality standard and valued produce safety information. Finally, multiple needs assessments have shown that low-income populations, including minority groups, have unique barriers to adopting food safety practices. The third study (Ch.3) evaluated a dialogue-based virtual food safety program for English- and Spanish-speaking low-income populations using the Theory of Planned Behavior (TPB). Findings suggest that the TPB helped to discern the behavior change intentions of this population and showed that the intervention was able to increase participants’ knowledge, attitudes toward the behavior, perceived behavioral control (PBC), subjective norms, and behavior change intentions. Future work could modify the program to fit other minority populations in the USA.</p>

本研究以網際網路做為企業行銷溝通之互動性媒介為觀點，以內容分析法進行兩部分之研究。第一部份以分析跨國運動商品企業網站首頁為題；第二部分則測度傳播策略呈現在跨文化運動商品網頁中的標準化程度，以期對跨國運動商品企業建置各國家地區網站與網頁之現況有一概括性的瞭解。 第一部份將運動商品企業網站首頁劃分為「內容」與「設計」兩項架構，分析12家跨國運動商品企業在美國、中國與台灣共計33個首頁樣本，發現中國與台灣併計為大中華地區所列載之內容項目與功能設計，與美國運動商品網站首頁之差異不大；但在線上購物機制上則仍未有成熟的環境與建置，此結果可呼應於其他跨文化行銷傳播研究的相關論述。 第二部分研究植基於傳統廣告內容的分析技術，變項涵括：「資訊內容」、「文化價值」與「創意策略」等三面向，檢測跨國運動商品企業設置於美國、中國與台灣地區共計211個網頁樣本。結果發現運動商品網頁確實是涉入度高、資訊承載量大的互動性媒體，偏向使用「獨立性文化價值」以傳達個體性而非集體性的文化概念。然而大中華區在廣告運用與網路媒體的開放性，複雜紛呈的文化價值表現，亦造成運動商品網頁的跨文化差異化。創意策略則使用商品的論點與細節，結合象徵性聯想與品牌熟悉度的方式，同時傳達品牌名稱、商標符號與名人代言的情境，以行銷每一季推陳出新的運動商品。 / This study regards the Internet as an interactive medium of corporate marketing communication, engages in two parts of studies by content analysis method. The first part analyzes sports-commodity multinational corporations’ home pages; the second part evaluates the degree of standardizations’ online communication strategies across differing cultures. And to comprehend summarized about how the sports-commodity MNCs set up regional websites. Divides into two frames of “content” and “design” categories, the first part analyzes 33 home-page samples in 12 sports-commodity MNCs among USA, China, and Taiwan. So that sports-commodity home pages’ content items and design functions have no remarkable difference. But the systems of online shopping environment are not mature in China and Taiwan. The result is coherent with past cross-cultural studies that compared marketing communications. On the basis of traditional advertising content study techniques, three explanatory variables are conducted, i.e. “information content”, “culture value” and “creative strategies”. Examining the 211 web-page samples in sports-commodity MNCs among USA, China, and Taiwan, the finding suggests that the high involvement nature of interactive medium is closely related to the informative web pages. And the predominant usage of “independent culture value” conveys individualism but collectivism cultural concepts. However, the liberalization of the Internet media and advertising usage; representation of complicated culture values, are the reasons to cause the cross-cultural diversity between localized sports-commodity MNCs’ web pages. To weed through the old to bring forth the new sports commodity every season, the MNCs have adapted their web creative strategies by products’ arguments and specifics, and integrating symbolic association and brand familiarization, with context of brand name, trademark and celebrity endorsers.
