Digital re-analysis of lost architecture and the particular case of Lutyens' Liverpool Metropolitan Cathedral

Research and critique of unbuilt or destroyed works of architecture is traditionally carried out through the examination of surviving information such as drawings, models, photographs, biographies and monographs. The case study presented here demonstrates that this approach cannot always give a full-picture of the architect or designer's intentions, and may miss inconsistencies in the design and links to other precedents or antecedents in such schemes. Here, we employ strategic contemporary digital representation techniques to re-present and re-analyse the evidence available for a particular architectural project. We describe a systematic methodology, which shows that these techniques can challenge or enhance current understanding. The focus therefore is on the digital re-analysis process that has been devised. Sir Edwin Lutyens' unbuilt Liverpool Metropolitan Cathedral design, that would have delivered one of the largest cathedrals in the world, is used as a case study. The findings reveal new information about the cathedral by following structured lines of enquiry generated from the study of primary and secondary source data, as well as serendipitous results that occur as a potential by-product of the methodological process.     

Extracting alternative machining features: An algorithmic approach

Automated recognition of features from CAD models has been attempted for a wide range of application domains. In this article we address the problem of representing and recognizing a complete class of features in alternative interpretation for a given design.We present a methodology for recognizing a class of machinable features and addressing the computational problems posed by the existence of feature-based alternatives. Our approach addresses a class of volumetric features that describe material removal volumes made by operations on three-axis vertical machining centers, including drilling, pocket-milling, slot-milling, face-milling, chamfering, filleting, and blended surfaces.This approach recognizes intersecting features and is complete over all features in our class; i.e., for any given part, the algorithm produces a set containing all features in our class that correspond to possible operations for machining that part. This property is of particular significance in applications where consideration of different manufacturing alternatives is crucial.This approach employs a class of machinable features expressible as MRSEVs (a STEP-based library of machining features). An example of this methodology has been implemented using the ACIS solid modeler and the National Institute's of Health C++ class library.

Prediction under uncertainty as a boundary problem: A general formulation using Iterative Closed Question Modelling

Making predictions about environmental systems is a challenge due to the high level of uncertainty involved. In this paper we give a general formulation of prediction under uncertainty as a boundary problem. This leads to development of a methodology for making predictions under uncertainty, named Iterative Closed Question Modelling (ICQM). ICQM involves iteratively devising questions and testing the certainty of their answers by creating complete model scenarios (complete taken to include structure, parameters and inputs for each scenario instance). The model scenarios are categorised in terms of which answer they support, and whether they are plausible or not. Using a simple two-parameter flow duration curve model, the paper demonstrates the application of ICQM using eight alternative uncertainty analysis techniques. ICQM provides a useful and generic approach to making predictions under uncertainty, helps to understand how existing techniques address the boundary problem differently and promotes the development of new techniques.     

西方执政合法性理论批判

执政合法性理论是西方政治哲学普遍关注的重大问题,从马克斯.韦伯到哈贝马斯,西方学者对这个问题做了深入的研究,提出了"合法化危机"的基本理论,但由于研究视角、方法和目的等方面的局限性,他们的研究也存在严重不足。坚持以马克思主义为指导,科学分析、研究和批判西方执政合法性理论,有助于加强中国共产党的执政能力建设,增强执政合法性。     

文学化叙事手法在夜景设计中的运用

从当代建筑美学的角度,通过对当代建筑设计风格和手法的借鉴,将即兴的、游戏式的设计手法运用到地标性建/构筑物的夜景照明设计中来;使其夜景形象呈现出多变、情节化、趣味化的景象。笔者通过对两个地标性建/构筑物夜景设计创作思路的展示,提出了以文学化的、轻松的、即兴的、游戏式的设计手法来完成通常我们认为严肃的地标性建筑夜景设计的可能性。     

‘Agitating people’s brains’: Noulan Cauchon and the City Scientific in Canada’s capital

Noulan Cauchon (1872–1935) was a founder of the Town Planning Institute of Canada and the Ottawa Town Planning Commission. He played a significant role in the planning of Canada’s capital city in the early twentieth century. This article traces the evolution of Cauchon’s planning ideas and their place within the Canadian planning profession, based upon his numerous public lectures, newspaper and journal articles. He was a close ally of Thomas Adams during the 1914‐26 campaign to extend town planning across Canada. Cauchon’s background as a railway engineer influenced his City Scientific approach to planning, which contrasted with the City Beautiful proposals for the capital produced for the federal government. This City Scientific approach became the dominant mode of planning in Canada after 1918. Cauchon produced a comprehensive zoning by‐law and many small‐scale planning schemes for the Ottawa area. Few of his proposals were implemented by the municipality, which deferred to the national government on most planning issues during this period. But Cauchon’s ideas influenced the early evolution of the profession in Canada and the redevelopment of the national capital after 1945.     

An integrated programme for critical thinking in information systems research

Abstract. This paper sets out to demonstrate that critical systems thinking can provide the necessary theoretical background for the development of an integrated approach to critical thinking in information systems research. Critical systems thinking is itself a relatively new development in management science. By about 1990, however, it had established itself on the basis of five commitments; to critical awareness, to social awareness, to complementarism at the level of methodology, to complementarism at the level of theory, and to human well-being and emancipation. The paper discusses these critical systems commitments and shows that each of them has, at one time or another, received attention in the literature on information systems. Addressing them as a whole, as in critical systems thinking, can yield an integrated programme for critical thinking in information systems research.     

第三景观宣言：吉尔·克莱芒的荒野 营造

以法国风景园林师吉尔·克莱芒的理论和作品为研 究的对象,拟从4个内容展开：第一,在描述其风景园林思想 体系的基础上,勾勒第三景观宣言的理论纲要;第二,以亨 利·马蒂斯公园为例,验证该理论在具体作品中的有效性; 第三,简论该公园呈现的荒野之境,阐述其生物多样性内 涵;第四,分析都市荒野中蕴含的自主性和抵抗性概念。本 研究的意义主要有三：一方面在国内学界比较系统地引介国 际前沿的风景园林理论;另一方面深度讨论设计与理论之间 相互转化的议题;同时,荒野中蕴含的自主性和抵抗性还拓 展了都市荒野的审美批判。
