Sommario/riassunto |

Relations between Inner Asian nomads and Chinese are a continuous theme throughout Chinese history. By investigating the formation of nomadic cultures, by analyzing the evolution of patterns of interaction |
|

|
|
|
|
|
|
|
|
along China's frontiers, and by exploring how this interaction was recorded in historiography, this looks at the origins of the cultural and political tensions between these two civilizations through the first millennium BC. The main purpose of the book is to analyze ethnic, cultural, and political frontiers between nomads and Chinese in the historical contexts that led to their formation, and to look at cultural perceptions of 'others' as a function of the same historical process. Based on both archaeological and textual sources, this 2002 book also introduces a new methodological approach to Chinese frontier history, which combines extensive factual data with a careful scrutiny of the motives, methods, and general conception of history that informed the Chinese historian Ssu-ma Ch'ien. |

Sommario/riassunto |
|
Providing a critical review of the current state of health promotion research. This book re-conceptualises the field of health promotion as collaborative and integrating enterprise, rather than as a battlefield for disciplinary and intellectual clashes. It makes a significant contribution to ongoing epistemological, theoretical and methodological debates in health promotion research. With contributors from Sweden, Switzerland, Denmark, Ireland, the UK and the US, Researching Health Promotion will be of interest to students and professionals working in health promotion, public heal |
