Use of gestalt in wayfinding design and analysis of wayfinding process

NIU Li, XU Leiqing, TANG Zhong

Frontiers of Structural and Civil Engineering 2008, Volume 2, Issue 4, Pages 386-390 doi: 10.1007/s11709-008-0040-8

Abstract: The authors brought forward the definition of “Gestalt space” and indicated this kind of space can be easily cognized. Three experiments showed that “classification” and “grouping” are the human strategies to solve wayfinding problems. “Similarity” and “Legibility” of the space are advantageous to help people to complete wayfinding tasks. The designer should provide the essential “Legibility” in Gestalt space, by using some techniques such as “break” and “accession” to settle the wayfinding problem.

TRADE-OFFS IN THE DESIGN OF SUSTAINABLE CROPPING SYSTEMS AT A REGIONAL LEVEL: A CASE STUDY ON THE NORTH

Frontiers of Agricultural Science and Engineering 2022, Volume 9, Issue 2, Pages 295-308 doi: 10.15302/J-FASE-2021434

Abstract:

Since the Green Revolution cropping systems have been progressively homogenized and intensified with increasing rates of inputs such as fertilizers, pesticides and water. This has resulted in higher crop productivity but also a high environmental burden due to increased pollution and water depletion. To identify opportunities for increasing the productivity and reducing the environmental impact of cropping systems, it is crucial to assess the associated trade-offs. The paper presents a model-based analysis of how 30 different crop rotations practiced in the North China Plain could be combined at the regional level to overcome trade-offs between indicators of economic, food security, and environmental performance. The model uses evolutionary multi-objective optimization to maximize revenues, livestock products, dietary and vitamin C yield, and to minimize the decline of the groundwater table. The modeling revealed substantial trade-offs between objectives of maximizing productivity and profitability versus minimizing ground water decline, and between production of livestock products and vitamin C yield. Six strategies each defining a specific combination of cropping systems and contributing to different extents to the various objectives were identified. Implementation of these six strategies could be used to find opportunities to mitigate the trade-offs between objectives. It was concluded that a holistic analysis of the potential of a diversity cropping systems at a regional level is needed to find integrative solutions for challenges due to conflicting objectives for food production, economic viability and environmental protection.

Effects of dwarfing genes on water use efficiency of bread wheat

Jiakun YAN, Suiqi ZHANG

Frontiers of Agricultural Science and Engineering 2017, Volume 4, Issue 2, Pages 126-134 doi: 10.15302/J-FASE-2017134

Abstract: Climate change has increased the risk of drought, which significantly limits plant productivity. Various ways of increasing water availability and sustaining growth of crop plants in drought-prone environments are available. Genetic advances in grain yields under rainfed conditions have been achieved with the introduction of dwarfing genes. A thorough understanding of the effects of different dwarfing genes on root growth, coleoptile length, grain yields and water using efficiency (WUE) will provide opportunities to select appropriate genes for breeding high WUE and grain yield cultivars. This review focuses on the mechanism involved in genes that reduce plant height and affect root and coleoptile length, their consequent effects on grain yields and WUE, and suggests that for rainfed and irrigation-limited environments, combining GAR and GAI dwarfing genes in breeding may help boost WUE and yields, and more materials from different parental sources should be collected to assess opportunities for potential comprehensive application of specific genes.
