Research on the Spatial–Temporal Changes of Regional Morphology of Residential Neighborhoods in County-Level Cities of China: Cases Studies on Qingcheng County,Wu’an City,Changxing County,Lianjiang County,and Jintang County

The extensive growth in most Chinese cities at the expense of local identities of living settlement. Taking the 60 residential neighborhoods in county-level cities of varied climate zones in China as examples, this paper explores their spatial–temporal changes and differences in morphology, based on 12 morphological indicators through Principal Component Analysis and correlation analysis by ArcGIS 10.2, SPSS 22, and Origin 2021. The results show that 1) the construction dating of the 60 sample neighborhoods conforms to the development of China’s housing reform; 2) the spatial morphology of residential neighborhoods in county-level cities of different climate zones could be charaterized by 5 factors, i.e. neighborhood shape, development intensity, neighborhood size, layout order, and aggregation degree; 3) the disparities in the spatial morphology of residential neighborhoods in the same climate zone in different period of time are mostly indicated with 3 morphological indicators, i.e. Building Density, Neighborhood Area, and Green Space Ratio; rather, the morphology of residential neighborhoods built during a same period of time varies largely between climate zones, mainly indicated with Green Space Ratio, Degree of Building Angle Disorder, and Degree of Building Distance Disorder; and 4) China’s housing policies, climatic conditions, residential building patterns, and the urbanization of each city together influence the spatial–temporal changes in the spatial morphology, offering references to policy making, planning, and construction to protect the regional characteristics in the future.     

人居视角地貌基本形态分类与山地聚落建设生态适宜性评价 ——以四川省渠县为例

适宜地貌是山地城乡聚落生态建 设的首要条件,而当前地貌基本形态分类所 沿用的区域地貌学方法,其视角为“从空中俯 瞰大地”,其结果不仅与人的实际感受存在 较大差别,更缺乏与自然生态环境的相关性, 难以有效地指导山地聚落生态建设。针对该 问题,本研究基于地貌基本形态分类视角向 “站在山下观山势（更符合人的实际感受）” 的人居视角的转变,通过分析相对高度和坡 度两大地貌基本形态分类因子与生态环境及 城乡聚落建设条件的相关性,在寻找地貌基 本形态分类与山地聚落建设生态适宜性评价 的关系中,构建出：以相对高度为一级分类因 子,以坡度为二级分类因子的地貌基本形态 分类方法,有效地引导城乡聚落的选址和聚 落建设用地的选择具有更强的生态适宜性。     

建筑图学的名作效应教学法——透视阴影教学研究

本文结合笔者从事的教学课题,主要讨论了建筑图学中透视阴影的有效教学。透视阴影课程为学生的设计素养及绘图能力打下坚实基础,但因其难学且枯燥等劣势让学生无法产生兴趣。笔者尝试将知名建筑与课本知识点相结合的手法,以名作效应激发学生的兴趣与热情。

Co-operation at work: a process-oriented perspective on joint activity in inter-organizational relations

In this paper the authors present a conceptual framework for analysing cooperation between organizations as a situated process, highlighting co-operation, co-ordination and co-construction as different modes of joint activity. Within this framework, the analysis of unexpected events becomes a crucial issue. The analytic power of reconstructing the (psycho-) logics of unexpected events in inter-organizational relations will be demonstrated in the presentation of selected outcomes of a research project on the dynamics of producer-supplier relationships in the German automobile industry. Also in this empirical part, the significance of trust and confidence in inter-organizational relations will be reflected.     

“远瞻”与“近交”——江苏盐城环保科技城规划设计的链接式思考

针对环保科技城规划中普遍存在的规划战略理念与实施操作脱节的情况,研究首先论述了规划中战略理念的"远瞻"和实施操作的"近交"两大层面对江苏盐城环保科技城规划的影响,以及二者在产业体系、空间布局和分期扩展等方面的呼应及链接,从而提出只有通过对"远瞻"定位与"近交"策略进行链接式思考,才能保证规划得以有效的贯彻与实施,才能更好地推动环保科技城的发展。     

Visual-based quadrotor control by means of fuzzy cognitive maps

By applying an image-based visual servoing (IBVS) method, the intelligent image-based controlling of a quadrotor type unmanned aerial vehicle (UAV) tracking a moving target is studied in this paper. A fuzzy cognitive map (FCM) is a soft computing method which is classified as a fuzzy neural system and exploits the main aspects of fuzzy logic and neural network systems; so it seems to be a suitable choice for implementing a vision-based intelligent technique. An FCM has been employed in implementing an IBVS scheme on a quadrotor UAV, so that the UAV can track a moving target on the ground. For this purpose, by properly combining the perspective image moments, some features with the desired characteristics for controlling the translational and yaw motions of a UAV have been presented. In designing a vision-based control method for a UAV quadrotor, there are some challenges, including the target mobility and not knowing the height of UAV above the target. Also, no sensor has been installed on the moving object and the changes of its yaw angle are not available. Despite all the stated challenges, the proposed method, which uses an FCM in controlling the translational motion and the yaw rotation of a UAV, adequately enables the quadrotor to follow the moving target. The simulation results for different paths show the satisfactory performance of the designed controller.     

Modeling target group heterogeneity in experimental consumer studies

Acceptance of a product by a consumer may result from a convoluted interplay between product attributes and individual characteristics of that consumer. Different methods that systematically combine product properties with consumer groups segmented on such characteristics have provided unprecedented insight, but ignore heterogeneity in acceptance within each consumer group. Although such knowledge is invaluable for targeted marketing, dedicated methods for consumer group heterogeneity are lacking. The authors aim to fill this gap by the Individual Differences (InD) method, which models differences between consumers within the same target group. The method scores the ‘diffusion’ within each group, shows how much each consumer contributes to that, and relates this information to product properties. Thereby also novel groups may be discovered, with attributes not covered in the consumer segmentation. The illustrative consumer study on apple juice reveals how young women differ in their price-consciousness and their acceptance on specific preparation technologies more than older women. Although men exhibit heterogeneity on the same product attributes, their mutual variability is considerably lower and they thereby form more homogeneous target groups.     

文化翻译观下的美剧字幕翻译

近年来美剧在中国日益流行,不仅促进了中西方文化的交流,也使得美剧字幕的翻译作为一个新兴的翻译领域逐渐受到重视。同时,由于中西方文化以及思维方式的不同,美剧的字幕翻译必然受到跨文化交际的影响。文章以文化翻译观为依据,以几部在中国热播的美剧字幕翻译为例来探讨美剧字幕翻译中文化信息的处理的几种方法。
