跨文化视域下的“伪对应”翻译——以浙江省公示语翻译为例

公示语翻译的目的是为了在译入语中找出同译出语相对的话语以传递译出语所表达的意思,双方间文化的差异使得翻译过程中特别需要警觉的是"伪对应"翻译,即形式上似乎完全一致而实际内涵根本不同的错译。本文以浙江省杭州市旅游景点和绍兴市名人故居公示语翻译为例,从文化关联理论和跨文化视域的角度,对公示语"伪对应"翻译问题进行了探讨,并提出有效的解决措施。

Ensemble Approaches to Estimating the Population Mean with Missing Response

We propose new ensemble approaches to estimate the population mean for missing response data with fully observed auxiliary variables. We first compress the working models according to their categories through a weighted average, where the weights are proportional to the square of the least‐squares coefficients of model refitting. Based on the compressed values, we develop two ensemble frameworks, under which one is to adjust weights in the inverse probability weighting procedure and the other is built upon an additive structure by reformulating the augmented inverse probability weighting function. The asymptotic normality property is established for the proposed estimators through the theory of estimating functions with plugged‐in nuisance parameter estimates. Simulation studies show that the new proposals have substantial advantages over existing ones for small sample sizes, and an acquired immune deficiency syndrome data example is used for illustration.     

Estimation of total electricity consumption curves by sampling in a finite population when some trajectories are partially unobserved

Millions of smart meters that are able to collect individual load curves, that is, electricity consumption time series, of residential and business customers at fine scale time grids are now deployed by electricity companies all around the world. It may be complex and costly to transmit and exploit such a large quantity of information, therefore it can be relevant to use survey sampling techniques to estimate mean load curves of specific groups of customers. Data collection, like every mass process, may undergo technical problems at every point of the metering and collection chain resulting in missing values. We consider imputation approaches (linear interpolation, kernel smoothing, nearest neighbours, principal analysis by conditional estimation) that take advantage of the specificities of the data, that is to say the strong relation between the consumption at different instants of time. The performances of these techniques are compared on a real example of Irish electricity load curves under various scenarios of missing data. A general variance approximation of total estimators is also given which encompasses nearest neighbours, kernel smoothers imputation and linear imputation methods.

论我国城镇化进程中传统村落的消失与保护

随着城镇化进程不断推进,农村劳动力逐渐向城市和城镇转移。在此过程中,传统村庄人口数量锐减,老龄人口与未成年人口占据了村庄人口的主要部分。即使这样,在农村剩余人口中,绝大多数未成年人有着强烈的进城意愿。因此,传统村落将面临人口数量逐渐减少,结构老龄化问题。长此以往,一些地区出现了传统村落的消失。传统村落承载着独特的民族文化与优秀文明,如果任其消亡,可能导致众多非物质文化的丢失与遗弃,在不断推进城镇化建设过程中,对传统村落承载的历史传统文化应有选择地进行继承和发展。     

Sex change and spatial distribution pattern in an intertidal holothurian Polycheira rufescens in the reproductive season

The patterns of sex change and spatial distribution in an intertidal holothurian, Polycheira rufescens (Chiridotidae; Echinodermata), were investigated on a stony beach in Amakusa, western Kyushu. Field caging experiments revealed that some individuals of P. rufescens underwent a sequential sex change from male to female via hermaphrodite stages and back to male again within a single reproductive season. The sex ratio of the population gradually changed from male dominance at first to equal proportions of males and females as the reproductive season progressed. Toward the end of the reproductive season, immature or spent individuals increased in proportion. Stone size appeared to be an important factor affecting the occurrence of P. rufescens individuals on a stony beach. Analysis of spatial distribution by means of Morisita's index of dispersion and nearest neighbor distances indicated that (i) males showed a slightly stronger tendency to aggregate than females, while females had a tendency toward uniform distribution; (ii) females tended to attract males, as shown by relatively short female-to-male distances; and (iii) there was a substantial variation in male-to-female distances, such that some males were positioned close to females while others were not. It may be suggested that spatial distribution of P. rufescens individuals during the reproductive period is partly dictated by the differential needs of individuals of different sexual states.

对右脑开发热的冷思考

右脑开发具有一定的科学依据和积极意义。右脑开发目标应定位在开发右脑潜能促进左右脑协调发展和发现、培养艺术才能两个方面。中国具有传统的右脑开发优势。当前的右脑开发热虽然在个别具体措施上具有可供借鉴之处,但商业化味道浓厚,其中掺杂许多伪科学的东西,发展趋势令人担忧。

A cluster problem as defined by nearest neighbours

Randomly generated points in R^d are connected to their nearest neighbours (Euclidean distance). The resulting connected clusters of points are studied. This paper examines questions related to the collection of clusters formed and to the internal structure of a cluster. In particular, the one-dimensional structure is examined in detail.
