This essay examines how aesthetic, corporate and cultural formations have radically altered. motorcycling and its image over the past two decades as a means to highlight more general changes in cultural politics, citizenship and governing through culture. The essay begins with the Guggenheim's The Art of the Motorcycle exhibit, treated. as a means for shaping and governing thought and conduct about and on motorcycles. The essay then addresses numerous articulations between aesthetic criteria and economic practices that have benefited. corporate and professional entities at the expense of long-time motorcyclists. Lastly, the essay formulates genealogical criteria for assessing attempts to represent culture in the hopes of more actively engaging in struggles over not just representation, but the activation of modes of thought, conduct and citizenship. 相似文献

上世纪20年代初期,随着经济发展、拥有治外法权的外国租界的存在以及民族主义幻想与实际的革命经费的需要等综合性因素,在上海出现了中国人开设的早期股票交易所。上海近代股票市场不同于世界其他地方,其投机性质十分明显。上海作为半殖民地和中西文化交汇处的特点决定了其股票市场和民族主义、中外文化、道德伦理冲突纠结在一起的发展特征。 相似文献

Nonparametric tests for the null hypothesis of no treatment effect in the mixed-model experiment which involves n randomly chosen subjects who respond once to each of ρ distinct treatments have been developed by Koch and Sen (1968), These tests were based on the assumption of compound symmetry of the error vectors and on the weaker assumption of diagonal symmetry of the error vectors. This paper considers an alternative (permutationally) distribution-free test under this latter assumption. The new test follows the same type of distribution theory as those in Koch and Sen, but utilizes the inherent invariance structure in a more visable and direct way. 相似文献

Much research has been conducted to develop confidence Intervals on linear combinations and ratios of variance components in balanced and unbalanced random models.This paper first presents confidence intervals on functions of variance components in balanced designs.These results assume that classical analysis of variance sums of squares are independent and have exact scaled chi-squared distributions.In unbalanced designs, either one or both of these assumptions are violated, and modifications to the balanced model intervals are required.We report results of some recent work that examines various modifications for some particular unbalanced designs. 相似文献

In response surface designs, it is not usually easy to handle the moment matrix X'X, especially for higher orders. This paper presents a method in which the moment matrix of a response surface of any order can be standardized, i.e., X'X splits into a diagonal matrix consisting of sub-matrices of lower order. This eases the calculation of the determinant and the inverse of X'X. The method has been illustrated with applications to second, third and fourth order response surfaces. 相似文献

Children (aged 9, 14, 19, and 24 months) were encouraged to use tools to achieve a demonstrated goal. Each tool was most efficiently applied when held by the handle with the thumb toward the head of the tool in a radial grip. The tools were presented at midline and oriented to the left and right on alternating trials, so the children who managed to grasp a tool in both orientations with the radial grip demonstrated planning of actions in advance. The tools included a spoon, hairbrush, toy hammer, and magnet; the goals were to feed one's self, feed another, brush one's hair, brush another's hair, hit pegs, and retrieve metal objects. Children were found to use more radial grips with the self‐directed tools (i.e., hairbrush‐to‐self and spoon‐to‐self), indicating that they could plan their actions better when directed toward the self than toward an external goal. 相似文献

The authors develop consistent nonparametric estimation techniques for the directional mixing density. Classical spherical harmonics are used to adapt Euclidean techniques to this directional environment. Minimax rates of convergence are obtained for rotation ally invariant densities verifying various smoothness conditions. It is found that the differences in smoothness between the Laplace, the Gaussian and the von Mises‐Fisher distributions lead to contrasting inferential conclusions. 相似文献
