The Maisin women of northeastern Papua New Guinea are among the last coastal Papuans to tattoo their faces. This article first describes the techniques and social process of Maisin tattooing. We then examine the resilience of the custom in light of changes in puberty rites and notions of gender. We argue that these contexts have lost their cultural salience as a result of the Maisins' incorporation into the larger Papua New Guinea society. Tattooing has acquired new significance as a marker of cultural identity in a multicultural setting and as a sign of the Maisin people's commercial success as makers of indigenous art.  相似文献

As technologies grow in complexity, firms often target their internal R&D resources on core competencies and utilize outside sources for supporting knowledge and technology. Where do firms turn to find such resources? This paper reports the perceptions of technology transfer managers in United States manufacturing firms toward federal and university labs and identifies the types of farms that are better positioned to utilize externally available technological resources. Based on replies from research-intensive companies within the United States, the authors find that larger firms with high research and development (R&D) budgets tend to ascribe greater significance to external sources than do smaller ones. Also, companies spending over $500 million in R&D rank universities the most significant external source of knowledge, followed by V S.-based firms, and then foreign firms.  相似文献

A pair of mandibular rami from a brown bear (Ursus arctosL.) was found at the rock shelter of the Grande-Rivoire in the Castelnovian level. Both exhibit a peculiar deformation affecting the bone between the first and second molars and the roots of these teeth.The perfect symmetry of this deformation, the absence of pathological features, and the misplacement of the teeth suggest that a thong had been placed around the mandible while the animal was young; the mandible then grew around the thong.The interest of this find is that it both demonstrates the taming of a bear and the complexity of the relationships between humans and animals during the late Mesolithic.  相似文献

Probabilistic preferences and choices and their connections to trip making and to distance-related demand are discussed. They are seen to aid aggregation. Risk aversion in retail shopping behavior and entropy maximizing as rational random behavior are examined. Elasticity of substitution is presented in terms of the covariance matrix. A Markovian phrasing and potential theory allow an analogy with deterministic choice: various applications of potential operators are outlined. Changes in utilities can only be modeled stochastically and some mechanisms are detailed. Price changes are random walked in time and space as a diffusion process. A fairly coherent theory of spatial demand emerges  相似文献
