汉语聚合词英译刍议

聚合词是汉语特有的结构性词形,这种独特性形成聚合词英译上的一个难点。通过对汉语语料英译的观察与分析发现,在三种语境下,聚合词英译可用直译;在聚合词充当回指语时,可用意译。此外聚合词充当回指语时,其语用意义与先行语相关联。这一发现揭示出聚合词译语的语义来源,也为聚合词的意译在理论上提出了一种解释。     

文艺学美学方法论视角下的电视新闻节目研究

从1958 年北京电视台开播,我国电视新闻正式诞生到现在,已经过去了57 年的时间。在这57 年的时间中,中国的电视 新闻事业得到了跨越性的发展。从最初的黑白电视到彩色画面;从只能节目录播到全程直播;从只有几个单独的电视台到现 在的电视新闻传输的全覆盖。尤其是90 年代后,随着现代科技的发展、新兴的数字技术给电视新闻传播带来了巨大的影响。 人们对于新闻节目的制作质量要求越来越高,但是电视新闻节目的质量却良莠不齐,所以如何吸收借鉴各行各业的优秀精华, 不断提升电视新闻节目的质量,带给观众美的享受,则是新闻工作者的不懈追求。而文艺学美学方法论中的诸多内容,都对电 视新闻节目的研究大有裨益     

“零度写作”在中国的接受过程

“零度写作”在20世纪80年代末成为文学理论研究与文学作品评论类文章中频繁亮相的术语,研究界用“零度写作”评价新写实主义、先锋派等后现代写作。一方面借用“零度写作”对主体的解构,以“零度情感”评价新写实小说,另一方面将“零度写作”理解为摆脱意识形态、摆脱历史记忆的纯粹文学样式,从而将不再承载某种主流意识形态,标榜无意义或消解中心的后现代写作称为“零度写作”。但不同的学者站在捍卫或批判后现代写作的立场,令“零度写作”在中国遭遇了冰火两重天的局面。

Pool‐Point Distribution of Zero‐Inventory Products

We study zero‐inventory production‐distribution systems under pool‐point delivery. The zero‐inventory production and distribution paradigm is supported in a variety of industries in which a product cannot be inventoried because of its short shelf life. The advantages of pool‐point (or hub‐and‐spoke) distribution, explored extensively in the literature, include the efficient use of transportation resources and effective day‐to‐day management of operations. The setting of our analysis is as follows: A production facility (plant) with a finite production rate distributes its single product, which cannot be inventoried, to several pool points. Each pool point may require multiple truckloads to satisfy its customers' demand. A third‐party logistics provider then transports the product to individual customers surrounding each pool point. The production rate can be increased up to a certain limit by incurring additional cost. The delivery of the product is done by identical trucks, each having limited capacity and non‐negligible traveling time between the plant and the pool points. Our objective is to coordinate the production and transportation operations so that the total cost of production and distribution is minimized, while respecting the product lifetime and the delivery capacity constraints. This study attempts to develop intuition into zero‐inventory production‐distribution systems under pool‐point delivery by considering several variants of the above setting. These include multiple trucks, a modifiable production rate, and alternative objectives. Using a combination of theoretical analysis and computational experiments, we gain insights into optimizing the total cost of a production‐delivery plan by understanding the trade‐off between production and transportation.

Marginal zero-inflated regression models for count data

Data sets with excess zeroes are frequently analyzed in many disciplines. A common framework used to analyze such data is the zero-inflated (ZI) regression model. It mixes a degenerate distribution with point mass at zero with a non-degenerate distribution. The estimates from ZI models quantify the effects of covariates on the means of latent random variables, which are often not the quantities of primary interest. Recently, marginal zero-inflated Poisson (MZIP; Long et al. [A marginalized zero-inflated Poisson regression model with overall exposure effects. Stat. Med. 33 (2014), pp. 5151–5165]) and negative binomial (MZINB; Preisser et al., 2016) models have been introduced that model the mean response directly. These models yield covariate effects that have simple interpretations that are, for many applications, more appealing than those available from ZI regression. This paper outlines a general framework for marginal zero-inflated models where the latent distribution is a member of the exponential dispersion family, focusing on common distributions for count data. In particular, our discussion includes the marginal zero-inflated binomial (MZIB) model, which has not been discussed previously. The details of maximum likelihood estimation via the EM algorithm are presented and the properties of the estimators as well as Wald and likelihood ratio-based inference are examined via simulation. Two examples presented illustrate the advantages of MZIP, MZINB, and MZIB models for practical data analysis.     

Conditional Akaike Information Criteria for a Class of Poisson Mixture Models with Random Effects

Focusing on the model selection problems in the family of Poisson mixture models (including the Poisson mixture regression model with random effects and zero‐inflated Poisson regression model with random effects), the current paper derives two conditional Akaike information criteria. The criteria are the unbiased estimators of the conditional Akaike information based on the conditional log‐likelihood and the conditional Akaike information based on the joint log‐likelihood, respectively. The derivation is free from the specific parametric assumptions about the conditional mean of the true data‐generating model and applies to different types of estimation methods. Additionally, the derivation is not based on the asymptotic argument. Simulations show that the proposed criteria have promising estimation accuracy. In addition, it is found that the criterion based on the conditional log‐likelihood demonstrates good model selection performance under different scenarios. Two sets of real data are used to illustrate the proposed method.
