一个亟待深入探讨的当代文论话题——关于当代文学的生存境况与发展前景的思考

当代中国文艺变革的实践 ,越来越清晰地证明 ,新媒体文化和大众日常艺术审美形态的崛起 ,极大地冲击着既定的文学、艺术形态和规范 ,改变其存在方式 ,促使其不断地走向大众 ,融入大众日常艺术审美活动 ,拓展了生存、发展空间 ;与此同时 ,变化着的文学、艺术则以独具的审美方式 ,积极地作用了新媒体文化和大众日常艺术审美活动 ,深化其艺术意蕴 ,提升其审美境界从而形成多元共生、悖立与互动的新文艺格局。可见 ,只有立足文艺变革实践 ,洞悉文艺变化发展的特点和规律 ,才能透过文学生存困窘的种种现象 ,窥探其发展的内在潜质与光明前景

ELICITING A DIRECTED ACYCLIC GRAPH FOR A MULTIVARIATE TIME SERIES OF VEHICLE COUNTS IN A TRAFFIC NETWORK

The problem of modelling multivariate time series of vehicle counts in traffic networks is considered. It is proposed to use a model called the linear multiregression dynamic model (LMDM). The LMDM is a multivariate Bayesian dynamic model which uses any conditional independence and causal structure across the time series to break down the complex multivariate model into simpler univariate dynamic linear models. The conditional independence and causal structure in the time series can be represented by a directed acyclic graph (DAG). The DAG not only gives a useful pictorial representation of the multivariate structure, but it is also used to build the LMDM. Therefore, eliciting a DAG which gives a realistic representation of the series is a crucial part of the modelling process. A DAG is elicited for the multivariate time series of hourly vehicle counts at the junction of three major roads in the UK. A flow diagram is introduced to give a pictorial representation of the possible vehicle routes through the network. It is shown how this flow diagram, together with a map of the network, can suggest a DAG for the time series suitable for use with an LMDM.     

开发区类企业的企业化博弈演进分析

基于我国开发区发展瓶颈现象和一个动态博弈模型，指出开发区类企业所具有的特殊的企业形态．该类企业在开发区初创阶段，以完成政府的效用为其义务．政府在开发区发展的各个阶段，其效用函数是不同的．当政府的期望效用基本完成之后，就应当逐渐退出其行政控制．由于政府的政绩诉求和权威惯性，其行政控制的退出往往比较迟缓．通过开发区类企业与政府的利益博弈，开发区类企业逐步完成其纯企业化的过程．这种博弈引发的交易成本可能使得开发区类企业的纯企业化过程时间过长，从而导致整个过程的非效率性．

THE SOCIAL IMPACT OF BROADBAND HOUSEHOLD INTERNET ACCESS

Broadband changes everything. Or so we are told. But does it? There is only one way to find out - follow people who move from narrowband to broadband internet access and see what changes. This paper reports exactly this kind of analysis using data from a two wave European panel study (e-Living) and the lagged endogenous regression approach to see if switching to broadband increases the time spent online, the use of online communication services, the breadth of internet activities and the amount of online spend, and whether it decreases the time spent watching TV and the level of social leisure activities. The results suggest, in the main, that switching to broadband made little difference for this group of early broadband adopters who were already heavy internet users. There was no evidence of an online spend or social leisure substitution effect although there was evidence of a reduction in time spent watching television, and an increase in email in use, time spent online and breadth of internet use. In all cases however it was the previous levels of behaviour that were the most significant and switching to broadband was, in general, one of the least strong effects.     

情态动词否定之研究

Palmer认为在英语语法中 ,最难描写的莫过于情态助动词系统 (Palmer,1 979:preface)。情态动词之所以纷繁复杂、难以描写是因为它们在各种英语文体中使用频率极高 ,并且表达的意义与人的情感和意念有着密切关系。由于情态动词的意义的多样性和模糊性 ,其否定形式及范围也是复杂多变的。我们可以依据Palmer对三类情态动词(推测性、义务性、原动性 )和两种情态级别 (可能级、必定级 )的划分 ,对情态动词的否定范围及语义进行分类分级研究 ;同时 ,鉴于可能级和必定级情态动词否定之间的语义约同现象 ,对逻辑等式Not -possible =Necessary -not;Not -necessary=Possible -not在情态动词句式中的操作规律加以探讨 ,结果表明该等式为解释情态动词否定形式间的互补现象提供了逻辑依据
