论唐湜的诗歌理论

唐湜诗歌评论的理论价值主要凸现在三个方面:一是在新诗的形式问题上,主张寓自由于格律之中,通过节奏与韵律来制约自由化,把自由化与格律化辩证统一起来;二是在新诗的审美追求上,认为新诗诗美的化境是走向意象的凝定;三是对诗歌含蓄美的倡导和肯定。这三个方面对于新诗的建设至今仍有现实意义。

A modified random-effect procedure for combining risk difference in sets of 2×2 tables from clinical trials

Summary Meta-analyses of sets of clinical trials often combine risk differences from several 2×2 tables according to a random-effects model. The DerSimonian-Laird random-effects procedure, widely used for estimating the populaton mean risk difference, weights the risk difference from each primary study inversely proportional to an estimate of its variance (the sum of the between-study variance and the conditional within-study variance). Because those weights are not independent of the risk differences, however, the procedure sometimes exhibits bias and unnatural behavior. The present paper proposes a modified weighting scheme that uses the unconditional within-study variance to avoid this source of bias. The modified procedure has variance closer to that available from weighting by ideal weights when such weights are known. We studied the modified procedure in extensive simulation experiments using situations whose parameters resemble those of actual studies in medical research. For comparison we also included two unbiased procedures, the unweighted mean and a sample-size-weighted mean; their relative variability depends on the extent of heterogeneity among the primary studies. An example illustrates the application of the procedures to actual data and the differences among the results.
