Globalization has contributed to the dismantling of national boundaries, which have enabled firms to compete and conduct business on a wider scale [Held, D., McGrew, A., Goldblatt, D., & Perraton, J. (1999). Global transformations. Politics, economics and culture. Cambridge: Polity Press]. Firms can move freely between different markets using Internet-based technology. While access to such markets can provide firms with greater choice of suppliers and cost efficiencies, they need to be aware of challenges that can influence their business performance. With this in mind, we examine how these factors influenced Alcoa Alumina's drive to a global procurement platform through a global marketplace. The staged adoption process experienced at Alcoa Alumina offers a learning opportunity for other firms considering the transition to global marketplace. 相似文献

Within the UK, the "Long Term Athlete Development" (LTAD) model has been proposed by a variety of national governing bodies to offer a first step to considering the approach to talent development. The model, which is primarily a physiological perspective, presents an advancement of understanding of developing athletic potential alongside biological growth. It focuses on training to optimize performance longitudinally, and considers sensitive developmental periods known as "windows of opportunity". However, it appears that there are a number of problems with this theoretical model that are not necessarily transparent to coaches. Principally, the model is only one-dimensional, there is a lack of empirical evidence upon which the model is based, and interpretations of the model are restricted because the data on which it is based rely on questionable assumptions and erroneous methodologies. Fundamentally, this is a generic model rather than an individualized plan for athletes. It is crucial that the LTAD model is seen as a "work in progress" and the challenge, particularly for paediatric exercise scientists, is to question, test, and revise the model. It is unlikely that this can be accomplished using classical experimental research methodology but this should not deter practitioners from acquiring valid and reliable evidence. 相似文献

This article maps how narrative inquiry—the use of story to study human experience—has been employed as both method and form to capture cross-cultural learning associated with Western doctoral students’ travel study to eastern destinations. While others were the first to employ this method in the travel study domain, we are the first to comprehensively explore the affordances and constraints of the methodology and the possibilities it holds for illuminating knowledge developments, community growth, and identity transformations on the part of participating students. Story fragments illustrating each of these opportunities and challenges are drawn from the China Study Abroad Program, a program sponsored by the University of Houston’s Asian American Studies Center that has been underway since 1995. Affordances of the narrative inquiry research method include such things as detailed accounts of individuals in interaction with diverse people/places/things and explications of stories people live in and by. Accounts, which are “true for now,” as opposed to true for all time and the dangers of human fallibility form two examples of narrative inquiry’s constraints. 相似文献
