景观设计中的象征阐释研究

景观承载着丰富的象征意义,同时,人们在欣赏景观时,也会通过自己的象征阐释拓展景观的内涵。人们的这种象征阐释源于象征化生存的人类本能,其心理基础是期待视野。象征阐释一般具有分为重构和建构两种类型,具有必然性、主动性、普泛性、差异性、动态性、自由性、多样性、通俗性、丰富性、不定性、可引导性等特征。对于象征阐释,景观设计者应在建构意义、语境指引、顺应读者等方面强化设计,才能有效地把读者的象征阐释指向预期的景观内涵。     

Theory of optimal blocking of nonregular factorial designs

The authors introduce the notion of split generalized wordlength pattern (GWP), i.e., treatment GWP and block GWP, for a blocked nonregular factorial design. They generalize the minimum aberration criterion to suit this type of design. Connections between factorial design theory and coding theory allow them to obtain combinatorial identities that govern the relationship between the split GWP of a blocked factorial design and that of its blocked consulting design. These identities work for regular and nonregular designs. Furthermore, the authors establish general rules for identifying generalized minimum aberration (GMA) blocked designs through their blocked consulting designs. Finally they tabulate and compare some GMA blocked designs from Hall's orthogonal array OA(16,2¹5,2) of type III.     

Sequential Procedure For Fixed Accuracy Estimation of the Population Size in Recapture Sampling

A sequential procedure is constructed to provide a fixed‐accuracy estimator for the number of faults in a system. This paper focuses on the case when faults are homogeneous. However, the method can be adapted to other models by choosing a more robust estimator. The accuracy of the estimator depends on the failure intensity, the length of testing period and the total number of faults in the system. Simulations illustrate the performance of the proposed procedure. The method is applied to an information system failure dataset.

The influence of rural-urban migration on migrants' fertility in Korea,Mexico and Cameroon

The paper presents a comparative analysis of the relationship between rural-urban migration and fertility in Korea, Mexico, and Cameroon. Using an autoregressive model, the results show a significant rural-urban migration adaptation effect in Korea and Mexico, a reduction of 2.57 and 1.45 children during the entire childbearing period, respectively, when compared to a rural stayer, even after the effect of selection has been controlled. Rural-urban migration has a very small impact on fertility in Cameroon. The unexpected result for Cameroon is due to the fact that the fertility-increasing effect of urban residency on the improved supply conditions of births, such as reduced infertility, offsets the fertility-depressing effect of urban residency on the demand for births. As a result of the adaptation to urban fertility norms, the number of country-wide births was reduced significantly in Mexico and Korea over the time periods studied.

Women at work in workplaces designed for men: Anthropometry and ergonomics

This article considers one of the sources of stress faced by modern working women: that of having to work in environments largely designed for men. It outlines how this problem has arisen, and examines the different ways in which it can be overcome, pointing up some of the main ergonomic issues that should be addressed in the design of work environments and facilities.     

Complete designs with blocks of maximal multiplicity

The set of distinct blocks of a block design is known as its support. We construct complete designs with parameters v(?7), k=3, λ=v ? 2 which contain a block of maximal multiplicity and with support size $\text{b}{}^1\text{= (}{}^{\mathrm{v}}{}_3\text{) ? 4(v ? 2)}$. Any complete design which contains such a block, and has parameters v, k, λ as above, must be supported on at most (^v₃) ? 4(v ? 2) blocks. Attention is given to complete designs because of their direct relationship to simple random sampling.
