胡适诗学的接受史考察——以懂与不懂之争为中心

作为中国现代诗学的开拓者,明白易懂是胡适白话诗学的核心。在近一个世纪里,这一诗学原则在得到认同的同时也不断遭受质疑,引起了一波又一波关于新诗懂与不懂的论争。在新诗发展精致化诉求中,面对现代派"不懂"的诗学,胡适有时在论争中进行自我阐发与完善,有时又不作分辨地接受来自不同诗学观念、风格美学的挑战与质疑。在大众化浪潮中,它开启诗歌如何向大众普及的讨论。在新中国新的历史语境中,又作为潜在的诗学依据,参与社会主义诗学话语的建构,呈现出新的接受特点。     

道儒相济的自由喧声--萨特的艺术与美学批评理论

自由精神是萨特整个艺术与美学批评理论的核心.在艺术创作、艺术接受、艺术功能三个方面,展现了萨特在艺术世界中寻绎自由实现自由捍卫自由的美学思路及其从个人(作者、读者)走向群体(社会、人类)之道儒相济的审美视角.这对我们今日重新认识艺术的自由本质,仍有其不可忽视的意义.     

论宋代文人对陶渊明的接受

陶渊明的诗文在文学接受史的长河中呈现出十分独特的形态,经历了一个由晦到显的漫长历程,在宋代才得到众多文人的推崇,他的文学地位也在此时得以确立。宋代文人对陶渊明诗文的推崇与解读揭示出文献在流传和接受过程中与时代文化精神的互动关系。     

The computational aspects of multiple attribute sampling procedures

One method of controlling the quality of incoming lots is through attribute sampling. To simultaneously control several (possibly dependent) attributes, properly chosen single attribute sampling plans can be merged into a multiple attribute sampling plan. The general form of such a plan is given and various alternatives are discussed. The multinomial distribution is used to develop formulae necessary for an analysis of a multiple attribute plan. Due to the lengthy nature of the calculations involved, a computer algorithm is outlined.     

A sampling plan for one-shot systems considering destructive inspection

Abstract

The paper is concerned with an acceptance sampling problem under destructive inspections for one-shot systems. The systems may fail at random times while they are operating (as the systems are considered to be operating when storage begins), and these failures can only be identified by inspection. Thus, n samples are randomly selected from N one-shot systems for periodic destructive inspection. After storage time T, the N systems are replaced if the number of working systems is less than a pre-specified threshold k. The primary purpose of this study is to determine the optimal number of samples n*, extracted from the N for destructive detection and the optimal acceptance number k*, in the sample under the constraint of the system interval availability, to minimize the expected cost rate. Numerical experiments are studied to investigate the effect of the parameters in sampling inspection on the optimal solutions.     

Importance sampling type estimators based on approximate marginal Markov chain Monte Carlo

We consider importance sampling (IS) type weighted estimators based on Markov chain Monte Carlo (MCMC) targeting an approximate marginal of the target distribution. In the context of Bayesian latent variable models, the MCMC typically operates on the hyperparameters, and the subsequent weighting may be based on IS or sequential Monte Carlo (SMC), but allows for multilevel techniques as well. The IS approach provides a natural alternative to delayed acceptance (DA) pseudo-marginal/particle MCMC, and has many advantages over DA, including a straightforward parallelization and additional flexibility in MCMC implementation. We detail minimal conditions which ensure strong consistency of the suggested estimators, and provide central limit theorems with expressions for asymptotic variances. We demonstrate how our method can make use of SMC in the state space models context, using Laplace approximations and time-discretized diffusions. Our experimental results are promising and show that the IS-type approach can provide substantial gains relative to an analogous DA scheme, and is often competitive even without parallelization.     

网络视频实时在线评论用户认可度的影响因素

目前，网络视频实时在线评论激增带来的信息爆炸，使实时在线评论信息管理成为重要议题。以往对实时在线评论的研究多集中于个人行为结果方面，而缺乏对实时在线评论信息管理问题的关注；同时，现有视频网站对实时在线评论信息的管理也存在诸多局限。以爱奇艺视频网站热度榜中的电影为样本，基于信息质量维度框架并采用Tobit模型对实时在线评论用户认可度的影响因素进行研究，结果发现：实时在线评论的新颖性、相似性、情感倾向性和信息丰富性，均对实时在线评论的用户认可度存在显著影响，其中新颖性和相似性影响作用最大。视频网站可以据此进一步强化实时在线评论管理，改善用户的体验，保持用户的粘性。     

系统信任、风险感知与转基因水稻公众接受——基于三省市调查数据的分析

基于重庆、湖北、浙江三省市城镇居民的入户抽样调查数据,分析我国公众对转基因水稻的接受态度及区域差异。研究发现,转基因水稻的接受态度存在区域差异,湖北、重庆分样本的接受度明显高于浙江;从影响因素来看,总体上城镇居民转基因水稻接受态度主要是受粮食安全收益感知、对科技系统的信任程度、健康与环境风险感知等因素影响,分样本比较显示浙江城镇居民的态度较之重庆、湖北受到更多风险感知因素的影响。基于此,提出了农业科技风险管理中注重粮食安全、培育科学自生系统等建议。     

Establishment of risk acceptance criteria using Life Quality Index: Application to the Indian context

The formulation of risk acceptance criteria may be coupled gainfully with a prediction of the of investment required to comply with it, an exercise which can benefit from the application of socioeconomic indicators. The Life Quality Index (LQI) is one such indicator which amalgamates human mortality and wealth creation and places an implicit economic value on reduction of life risk. While there have been a number of studies to demonstrate the application of LQI pertaining to various technological systems, the present work extends it to estimate the sectoral level investment needed to reduce public risks to within the As Low As Reasonably Predictable region for the chemical industry, with specific illustration of the methodology for India. The potential reduction in public individual risk is computed as a function of percentage increase in safety investment expressed as a fraction of the industry's contribution to the nation's GDP. In addition, using a new, more accurate expression, estimates of a related parameter, the implied cost of averting a fatality (ICAF), are obtained for a number of developed economies and India. The ICAF estimates show reasonable agreement with the value of statistical life (VSL), a parameter which is integral to cost-benefit analysis of safety and environmental regulations.
