Kenya is an important tourist destination in Africa accounting for over 6% of the total international tourist arrivals to the continent. However, in recent years Kenya's tourism industry has been experiencing problems of poor performance and continuing decline in the number of international tourist arrivals. This study examines the main characteristics of the country's tourism product vis‐a‐vis the changing trends in global tourism market demands. It is argued that the underlying cause of the recent poor performance of the tourism industry relates to the nature of the country's tourism product. Over the years, Kenya has been offering a limited tourism product that is based on beach and wildlife tourism. Also, the marketing of Kenya mainly depends on overseas tour operators who mainly sell inclusive tour packages. Thus, the form of tourism product that is offered by Kenya has not responded to the recent changes and trends in international tourism market demands. Post‐modern tourists, particularly tourists from developed countries, are increasing becoming aware of the negative impacts of mass tourism and are increasingly looking for alternative tourism products that provide a deeper and more meaningful experience. Thus, if Kenya is to rejuvenate its tourism industry there is need for the country to provide a diverse alternative tourism product which is more appealing to the post‐modern tourists. 相似文献

Abstract Many countries have implemented safety and performance requirements for children's products. There is, however, a need to harmonize existing legislation and standards to facilitate a uniform flow of trade. At the same time, it is essential to extend existing requirements to restrict certain hazards which have not been covered in the past. In CEN, the European Committee for standardization, several technical committees are developing European Standards for products to be used by or for children. On a global level as well, within ISO, there are standardization projects covering such products. Child safety is the main objective for the standardization work on: ?Safety of toys (CENATC 52, ISO/TC 181) ? Child use and care articles (CEN/TC 252) ?Playground equipment for children LCEN/TC 136/SC 1) ? Children's furniture (CEN/TC 207, ISO/TC 136( ?Child-resistant packaging (CEN/TC 261/SC 2, ISO/TC 122) Children's products constitute a group of consumer products with large variations between the different products. Nevertheless, since they all come in contact with children (and their parents), several hazards associated with these products are similar for the various products. This is reflected in the work of CEN/TC 252, Child use and care articles, established in 1990. To establish a horizontal framework for the hazard-based approach, CEN/ TC 252 created a working group with the task to specify general and common safety requirements (WG 6). Five working groups started the elaboration of product standards in parallel. The traditional concept of a standardization project was found inadequate and other solutions were sought. Finally, it was decided to combine the results from working group 6 into one guidance document, to be published as a CEN Report. 相似文献

Abstract The field of “custom communications” is a growing multi-billion dollar market. Custom publishing of magazines and books is a significant segment of the pie, proving the continuing value of print for creating stronger bonds with customers. This article describes a variety of applications for custom publishing in marketing products and services, with important implications for the promotional products industry. The author, who has ghost-written a book for a small advertising agency, focuses on the high potential for specialized magazines and well-written books that target an audience accurately. Included is cogent advice to promotional products professionals on how to go about creating an effective custom publication. 相似文献
