图像时代包装设计之美学解析

图像时代的包装设计与以往时代有着显著的差异,商品对象的使用价值被边缘化,功能性要素隐退至二线,视觉性的图像符号成为设计关注的焦点.整个设计呈现出区别于以往时代的美学新质:强调图像的观赏性,图像能指的虚拟性,图像审美的随意性和前快乐性,图像生产的间接性.这种新质重构了审美主体的心理,生成了一种新感性,并以一种无意识的方式将人们的消费欲望内化为一种时尚信仰与自觉的情感选择,从而建构了一种关于消费主义的价值神话与话语霸权,完成了物(商品)对人(主体)的控制,深刻地表征了人的复杂的社会关系与权力形式.     

浅析城市色彩设计对于城市规划的意义

城市色彩规划设计在现代城市建设中的具有重大的现实意义,主要体现在以下几个方面：城市色彩是城市人居环境质量的重要组成部分,是城市历史文化的重要载体,是城市现代文明的体现,同时也是矫正城市建筑无序状态的重要手段。     

Two-dimensional balanced sampling plans excluding adjacent units

Hedayat et al. [Sampling plans excluding contiguous units. J. Statist. Plann. Inference 19, 159–170, Designs in survey sampling avoiding contiguous units. In: Krishnaiah, P.R., Rao, C.R. (Eds.), Handbook of Statistics, vol. 6. Elsevier, Amsterdam, pp. 575–583] first introduced balanced sampling plans for the exclusion of contiguous units. Sampling plans that excluded the selection of contiguous units within a given sample, while maintaining a constant second-order inclusion probability for non-contiguous units, were investigated for finite populations of N units arranged in a circular, one-dimensional ordering. While significant advancements have been made in the identification and generalizations of such plans—commonly referred to as BSA sampling plans—little is known concerning the extension of such sampling plans to multi-dimensional populations. This paper will present a review of the pertinent results of one-dimensional BSA sampling plans and a discussion concerning the properties of two-dimensional BSA sampling plans.     

Minimax designs for estimating slopes in a trigonometric regression model

Abstract

Designs for the first order trigonometric regression model over an interval on the real line are considered for the situation where estimation of the slope of the response surface at various points in the factor space is of primary interest. Minimization of the variance of the estimated slope at a point maximized over all points in the region of interest is taken as the design criterion. Optimal designs under the minimax criterion are derived for the situation where the design region and the region of interest are identical and a symmetric “partial cycle”. Some comparisons of the minimax designs with the traditional D- and A-optimal designs are provided. Efficiencies of some exact designs under the minimax criterion are also investigated.     

Orthogonal arrays of strength three from regular 3-wise balanced designs

The construction given in Kreher, J Combin Des 4 (1996) 67 is extended to obtain new infinite families of orthogonal arrays of strength 3. Regular 3-wise balanced designs play a central role in this construction.     

Cumulative cohort design for dose-finding

We introduce a new design for dose-finding in the context of toxicity studies for which it is assumed that toxicity increases with dose. The goal is to identify the maximum tolerated dose, which is taken to be the dose associated with a prespecified “target” toxicity rate. The decision to decrease, increase or repeat a dose for the next subject depends on how far an estimated toxicity rate at the current dose is from the target. The size of the window within which the current dose will be repeated is obtained based on the theory of Markov chains as applied to group up-and-down designs. But whereas the treatment allocation rule in Markovian group up-and-down designs is only based on information from the current cohort of subjects, the treatment allocation rule for the proposed design is based on the cumulative information at the current dose. We then consider an extension of this new design for clinical trials in which the subject's outcome is not known immediately. The new design is compared to the continual reassessment method.     

论小康社会的法治模式

小康社会法治模式是依据法治的分类学说和全面建设小康社会的现实社会基础而提出的一种社会转型时期的法治形态。小康社会法治模式是法治的初级形态,它既具有法治的普适性特点,又有与法治常态相区别的特殊性。小康社会全面落实依法治国方略,就是要分步骤地落实党领导人民治理国家的各项具体法治。     

Cross-over Designs in the Presence of Higher Order Carry-overs

In cross-over experiments, where different treatments are applied successively to the same experimental unit over a number of time periods, it is often expected that a treatment has a carry-over effect in one or more periods following its period of application. The effect of interaction between the treatments in the successive periods may also affect the response. However, it seems that all systematic studies of the optimality properties of cross-over designs have been done under models where carry-over effects are assumed to persist for only one subsequent period. This paper proposes a model which allows for the possible presence of carry-over effects up to k subsequent periods, together with all the interactions between treatments applied at k + 1 successive periods. This model allows the practitioner to choose k for any experiment according to the requirements of that particular experiment. Under this model, the cross-over designs are studied and the class of optimal designs is obtained. A method of constructing these optimal designs is also given.     

What Parents Learn From Experience: The First Child as a First Draft?

This study sought evidence for the proposition that experiences with earlier‐born adolescents will improve parents' interactions with and parenting of later‐born adolescents. Participants were mothers, fathers, and both first‐ and second‐born siblings from 392 families participating in a longitudinal study. To collect information on siblings' family experiences, family members were interviewed individually in their homes. During the subsequent 2 to 3 weeks, 7 evening telephone interviews were also conducted, which focused on siblings' daily activities. Findings suggest that when parent‐adolescent relationships were measured at the same age for both siblings, parents experienced less conflict with their second‐born as compared with their firstborn adolescent offspring and exhibited greater knowledge of their second‐born offspring's daily activities as compared with their firstborns' daily experiences. These results are consistent with the notion that parents may learn from their childrearing experiences.
