The Consistent System

The Consistent System (CS) is an interactive computer system for researchers in the behavioral and policy sciences and in fields with similar requirements for data management and statistical analysis. The researcher is not expected to be a programmer. The system offers a wide range of facilities and permits the user to combine them in novel ways. In particular, tools for statistical analysis may be used in combination with a powerful relational subsystem for data base management. This paper gives an overview of the objectives, capabilities, status, and availability of the system.     

“新感觉派”的狐步舞：——现代小说创作中的“意识流”最初尝试

在文学"意识流"最初尝试的问题上,中国"新感觉派"的"狐步舞",从接受心态来说,"跳"得既时兴又焦灼;从接受实践来讲,似乎"把根留住"的情况要多一些.不过,总体的实际运作水准参差不齐,模仿的痕迹不同程度地依然存在,尽管如此,他们的最初尝试毕竟是当时历史产物下具有先锋性质的一次艺术实验,所以无可避免地要有相当的稚嫩性付出.要不然,哪有往后中国文学繁荣兴盛和中外文学关系健康发展之收获的喜悦呢?!     

Data depth and correlation

Summary: We describe depth–based graphical displays that show the interdependence of multivariate distributions. The plots involve one–dimensional curves or bivariate scatterplots, so they are easier to interpret than correlation matrices. The correlation curve, modelled on the scale curve of Liu et al. (1999), compares the volume of the observed central regions with the volume under independence. The correlation DD–plot is the scatterplot of depth values under a reference distribution against depth values under independence. The area of the plot gives a measure of distance from independence. Correlation curve and DD-plot require an independence model as a baseline: Besides classical parametric specifications, a nonparametric estimator, derived from the randomization principle, is used. Combining data depth and the notion of quadrant dependence, quadrant correlation trajectories are obtained which allow simultaneous representation of subsets of variables. The properties of the plots for the multivariate normal distribution are investigated. Some real data examples are illustrated. *This work was completed with the support of Ca Foscari University.     

“意识流”流入新时期文坛流程述略

“意识流”是舶来品 ,学界大概对此没做过传入流程的审理。国内大量文学史料雄辩地证明 :继中国现代文苑之后 ,它在新时期文坛的“流速”不减 ,直接引发了中国当代小说的文体变革。这充分反映出新时期文坛有识之士不断沉淀的现代意识之雄起 ,以及他们面对外来文化以我为主的价值取向     

试论普鲁斯特的文学创作

法国意识流小说大师普鲁斯特以反传统的写作风格和反叛的艺术思想在文学界和文学评论界引起了强烈的震撼.他的超长篇小说<追忆似水年华>一直被视为法国20世纪上半叶甚至是整个20世纪最伟大的文学杰作.其随笔体风格和"以乱取胜"的叙述手法打破了常规,是对根深蒂固的规范准则的颠覆和对传统秩序的解构.在为我们带来全新写作风格的同时,普鲁斯特笔下也为我们带来了一个全新的世界.     

内心独白与诗化建构--伍尔夫小说创作论

伍尔夫的意识流小说影响极大,她的小说以新的内心话语和独特的结构形式宣告了崭新的小说美学原则的确立.在小说技法上,她纯熟地运用绘画的"构图艺术"、宏观的透视方法、主导的象征意象来丰富小说艺术的表现功能;她通过"内心独白"和"诗化小说"来展现人物心灵,刻画人物形象,构筑小说的独特意境,赋予小说美的内涵和意蕴.     

An efficient polynomial space and polynomial delay algorithm for enumeration of maximal motifs in a sequence

In this paper, we consider the problem of enumerating all maximal motifs in an input string for the class of repeated motifs with wild cards. A maximal motif is such a representative motif that is not properly contained in any larger motifs with the same location lists. Although the enumeration problem for maximal motifs with wild cards has been studied in Parida et al. (2001), Pisanti et al. (2003) and Pelfrêne et al. (2003), its output-polynomial time computability has been still open. The main result of this paper is a polynomial space polynomial delay algorithm for the maximal motif enumeration problem for the repeated motifs with wild cards. This algorithm enumerates all maximal motifs in an input string of length n in O(n ³) time per motif with O(n) space, in particular O(n ³) delay. The key of the algorithm is depth-first search on a tree-shaped search route over all maximal motifs based on a technique called prefix-preserving closure extension. We also show an exponential lower bound and a succinctness result on the number of maximal motifs, which indicate the limit of a straightforward approach. The results of the computational experiments show that our algorithm can be applicable to huge string data such as genome data in practice, and does not take large additional computational cost compared to usual frequent motif mining algorithms.

Perceptions concerning research integrity and the practice of data audit in the biotechnology industry

A survey was conducted in order to evaluate the responses of biotechnology executives concerning their perceptions of the frequency of questionable R & D studies performed in their companies and to assess the extent to which their companies voluntarily conducted data audits. Data audit was found to be commonly practiced on a voluntary basis by biotechnology companies, in contrast to its almost lack of practice by universities. However, public companies were more likely to practice data auditing than privately held companies. Moreover, the likelihood that managers suspected or detected questionable studies in their companies was significantly increased if the company practiced data auditing.     

Ain't Behavin': Forecast Errors and Measurement Errors in Early GNP Estimates

Revisions of the early GNP estimates may contain elements of measurement errors as well as forecast errors. These types of error behave differently but need to satisfy a common set of criteria for well-behavedness. This article tests these criteria for U.S. GNP revisions. The tests are similar to tests of rationality and are based on the generalized method of moments estimator. The flash, 15-day, and 45-day estimates are found to be ill behaved, but the 75-day estimate satisfies the criteria for well-behavedness.
