How is ‘authentic’ linguistic femininity in Japan manifested in popular texts? We analyze the dialogue of female characters in Wakaba, a 2005 Japanese drama set in two very different parts of ‘regional’ Japan – Miyazaki and Kobe. Through this analysis, we examine two contradictory discourses circulated through popular media. The first is that linguistic femininity is based in Standard Japanese – a surprisingly persistent ideology despite a current trend to examine cases in which language ideology and practice do not match. Other studies reflect another dominant discourse, that of the ‘authentic’ dialect speaker, who expresses local alignment by using dialect forms outside the bounds of ideologically modern linguistic forms. The tension between acting linguistically feminine and ‘authentically’ local raises some interesting questions for Japanese language and gender studies, including studies of gendered representations: are women who are speakers of regional dialects authentically ‘feminine’? Can they be? Do some dialects express femininity better than others?  相似文献

Recommended methods for analyzing unbalanced two-way data may be classified into two major categories:the parametric interpretation approach and the model comparison approach. Each approach has its advantages and its drawbacks. The main drawback of the parametric interpretation approach is non-orthogonality.For the model comparison approach the main drawback is the dependence of the hypothesis tested on the cell sizes. In this paper we provide examples to illustrate these drawbacks.  相似文献

Relative income differences are likely to lead to envy within a reference group. Envy in turn influences social behavior and individual performance. While positional concerns are apparent in daily life, empirical evidence is rare in the economic literature. This paper investigates the impact of the relative income position on individuals’ performance or productivity. As ?performance“ is difficult to measure we turn to soccer players whose performance has been well documented. The broad sample covers eight seasons of the German premier soccer league (Bundesliga) between 1995 and 2004, and includes 1040 players, a salary proxy and several performance variables. The results show that player performance is strongly affected by relative income position. A disadvantage in the relative income position reduces productivity. The larger the income differences within a team, the stronger are the effects of positional concern. Team composition also significantly affects behaviour.  相似文献

Ranked set sampling is a procedure which may be used to improve the precision of the estimator of the mean. It is useful in cases where the variable of interest is much more difficult to measure than to order. However, even if ordering is difficult, but there is an easily ranked concomitant variable available, then it may be used to “judgment order” the original variable. The amount of increase in the precision of the estimator is dependent upon the correlation between the 2 variables.  相似文献

Using the ‘ratio’ method an easily implemented algorithm is derived for the generalised inverse Gaussian distribution. Computer timings and efficiency calculations show that the procedure is fast over a wide range of distribution parameter values.  相似文献

This paper develops a new class of measures of mobility as an equalizer of longer-term incomes—a concept different from other notions such as mobility as time-independence, positional movement, share movement, income flux, and directional income movement. A number of properties are specified leading to a class of indices, one easily-implementable member of which is applied to data for the USA and France. Using this index, income mobility is found to have equalized longer-term earnings among US men in the 1970s but not in the 1980s or 1990s. In France, though, income mobility was equalizing throughout, and it has attained its maximum in the most recent period.  相似文献

This article provides an expository account of the multivariate autoregressive moving average models and proposes an extended sample cross-correlation approach for practical model identification. An iterative model building procedure for applying these models to real data is discussed and demonstrated by analyzing the 5-series U.S. Hog Data.  相似文献
