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

Charles Edouard Brown-Séquard used observation of recovered patients and experimental animals to support his theory of cerebral localization. Recovery theories assume that the nervous system is composed of one organ or many, and that each organ has one function or many. From his own studies as well as others, Brown-Séquard concluded that the brain contained at least nine separate organs, each with a single distinct function, and that each organ is organized, not as a geographically isolated cluster of neurons, but as a widely disseminated network. According to his view, function is not uniformly distributed in an organ. Focal necrosis of part of an organ temporarily inhibits the action of distant, undamaged parts; resolution of this inhibition results in recovery. Using this theory of cerebral localization and recovery, Brown-Séquard practiced an early form of scientific neurology. 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
