Communication plays very different parts in two of the most influential political works of the last 500 years, The Prince by Niccolo Machiavelli (1469–1527) and Utopia by Sir Thomas More (1478–1535). The contrasts between More's carefully controlled and Machiavelli's unconstrained political communication shed light on the communication issues and practices of their times, some of which may still figure in relations between state and citizen. 相似文献

I review the recent literature on the determinants and effects of right-to-work (RTW) laws. The focus is primarily on the
econometric studies published since the early 1980s. Five major areas of impact are assessed: unionization, free riding, union
organizing activities and successes in NLRB elections, wage structure, and state industrial development. While individual
findings are quite sensitive to model specification, the accumulated evidence indicates that RTW laws have at least a significant
short-run impact on all of these areas except perhaps wages. 相似文献

This article describes a cutpoint sampling method for efficiently sampling from an n-point discrete distribution that preserves the monotone relationship between a uniform deviate and the random variate it generates. This property is useful for developing a sampling plan to reduce variance in a Monte Carlo or simulation study. The expected number of comparisons with this method is derived and shown to be bounded above by (m + n ?1)/n, where m denotes the number of cut-points. The alias sampling method, which is regarded as the most efficient table sampling technique, generally lacks the monotone property and requires 2n storage locations, whereas the proposed cutpoint sampling method requires m + n storage locations. The article describes two modifications for cases in which n is large and possibly infinite. It is shown that circumstances arise in which the cutpoint method requires fewer comparisons on average than the alias method does for exactly the same space requirement. The article also describes an algorithm to implement the proposed method. 相似文献

Dialect contact and distinctiveness: The social meaning of language variation in an island community 下载免费PDF全文
In this paper, we analyse linguistic variables which are well‐established in British English, the vowels in the trap and bath lexical sets. We demonstrate that the social meanings of these variables are both historically substantiated and locally‐elaborated. Our data is taken from the speech of individuals living on the Isles of Scilly, a group of islands off the south‐west coast of England. Our initial analysis shows that trap and bath variants found on the islands are linked to contact with Standard English English, on the one hand, and the nearest neighbouring variety of Cornish English, on the other. The general distribution of variants is shown to reflect educational differences amongst our speakers. However, two case studies show speakers using forms atypical of their education type in order to position themselves in interactionally‐dynamic ways. This reveals how speakers exploit the multidimensional meanings of linguistic variants to reflect and construct local practices and alignments. 相似文献

Summary. Complex survey sampling is often used to sample a fraction of a large finite population. In general, the survey is conducted so that each unit (e.g. subject) in the sample has a different probability of being selected into the sample. For generalizability of the sample to the population, both the design and the probability of being selected into the sample must be incorporated in the analysis. In this paper we focus on non-standard regression models for complex survey data. In our motivating example, which is based on data from the Medical Expenditure Panel Survey, the outcome variable is the subject's 'total health care expenditures in the year 2002'. Previous analyses of medical cost data suggest that the variance is approximately equal to the mean raised to the power of 1.5, which is a non-standard variance function. Currently, the regression parameters for this model cannot be easily estimated in standard statistical software packages. We propose a simple two-step method to obtain consistent regression parameter and variance estimates; the method proposed can be implemented within any standard sample survey package. The approach is applicable to complex sample surveys with any number of stages. 相似文献

Reputational Capital and Academic Pay 总被引:2,自引:0,他引:2
This article examines how research productivity, administrative service, and teaching affect reputational capital in the market for academic economists. Also, we investigate the issue of the durability of reputational capital, estimating the penalties associated with gaps in research output. Our results reveal that (1) the market makes a distinction between the quantity and the quality of an individual's research output, (2) a smaller number of frequently cited papers enhances reputational capital more than a greater number of less frequently cited papers, (3) reputational capital does not depreciate rapidly during research breaks, and (4) the market does not discount co-authored papers. 相似文献

Infants (n = 24, mean age 13 months and n = 24, mean age 19 months) were tested on an extension of the method introduced by Tomasello and Haberl (2003) to examine the understanding of another person’s interest in a novel object. Four objects were presented serially. For two objects, infants played with an experimenter. The infant played with one object alone, and the experimenter played with one object alone. Finally, all four objects were presented together, and the experimenter excitedly asked for one without indicating which. Results showed that younger infants tended to chose the object that they had not yet played with, whereas older infants were significantly more likely to choose the object that the experimenter had not yet played with. These results are discussed in the context of research on the development of understanding diversity of simple object‐directed attitudes in the second year of life. 相似文献
