Dawes* and Michael J. Ostwald Abstract A Pattern Language by Christopher Alexander is renowned for providing simple, conveniently formatted, humanist solutions to complex design problems ranging in scale from urban planning through to interior design. This text is also believed to be the most widely read architectural treatise ever published. Despite this, there is also little acknowl- edgement in its popular reception that it is only one part of a trilogy of works documenting Alexander’s ‘second theory’ of architecture. Thus, while A Pattern Language is widely referenced in architectural scholarship, most of these references simply acknowledge its existence and fail to engage with its content. Furthermore, the literature that does critically engage with Alexander’s theory, challenging its ideas and assumptions, is often difcult to fnd, and the criti- cisms are diverse and complex. The intent of this paper is to facilitate a deeper understanding of these criticisms and the relationships between them. The 28 criticisms identifed in past research are organised hierarchically in this paper into three tiers representing those associated with the: (i) conceptualisation, (ii) development and documentation and, (iii) implementation and outcomes of Alexander’s theory. The relationships between these criticisms are then mapped diagrammatically thereby forming the basis for thematic groupings within each hierarchical tier. This organi- sation reveals that only two criticisms relate to the concept of pattern languages in isolation, while the remainder arise, directly or indirectly, from Alexander’s idiosyncratic ontological and epistemological positions. The conclusion analyses the relationships between the criticisms to develop a holistic and understanding of where the problems in Alexander’s theory might lie.

    Neuroscience, the Natural Environment, and Building Design. Nikos A. Salingaros, Professor of Mathematics, University of Texas at San Antonio. Kenneth G. Masden II, Associate Professor of Architecture, University of Texas at San Antonio. Presented at the Bringing Buildings to Life Conference, Yale University, 10-12 May 2006. Chapter 5 of: Biophilic Design: The Theory, Science and Practice of Bringing Buildings to Life, edited by Stephen R. Kellert, Judith Heerwagen, and Martin Mador (John Wiley, New York, 2008), pages 59-83. Abstract: The human mind is split between genetically-structured neural systems, and an internally-generated worldview. This split occurs in a way that can elicit contradictory mental processes for our actions, and the interpretation of our environment. Part of our perceptive system looks for information, whereas another part looks for meaning, and in so doing gives rise to cultural, philosophical, and ideological constructs. Architects have come to operate in this second domain almost exclusively, effectively neglecting the first domain. By imposing an artificial meaning on the built environment, contemporary architects contradict physical and natural processes, and thus create buildings and cities that are inhuman in their form, scale, and construction. A new effort has to be made to reconnect human beings to the buildings and places they inhabit. Biophilic design, as one of the most recent and viable reconnection theories, incorporates organic life into the built environment in an essential manner. Extending this logic, the building forms, articulations, and textures could themselves follow the same geometry found in all living forms. Empirical evidence confirms that designs which connect humans to the lived experience enhance our overall sense of wellbeing, with positive and therapeutic consequences on physiology.

  • Wiki As Pattern Language
    Wiki as Pattern Language Ward Cunningham Cunningham and Cunningham, Inc.1 Sustasis Foundation Portland, Oregon Michael W. Mehaffy Faculty of Architecture Delft University of Technology2 Sustasis Foundation Portland, Oregon Abstract We describe the origin of wiki technology, which has become widely influential, and its relationship to the development of pattern languages in software. We show here how the relationship is deeper than previously understood, opening up the possibility of expanded capability for wikis, including a new generation of “federated” wiki. [NOTE TO REVIEWERS: This paper is part first-person history and part theory. The history is given by one of the participants, an original developer of wiki and co-developer of pattern language. The theory points toward future potential of pattern language within a federated, peer-to-peer framework.] 1. Introduction Wiki is today widely established as a kind of website that allows users to quickly and easily share, modify and improve information collaboratively (Leuf and Cunningham, 2001). It is described on Wikipedia – perhaps its best known example – as “a website which allows its users to add, modify, or delete its content via a web browser usually using a simplified markup language or a rich-text editor” (Wikipedia, 2013). Wiki is so well established, in fact, that a Google search engine result for the term displays approximately 1.25 billion page “hits”, or pages on the World Wide Web that include this term somewhere within their text (Google, 2013a). Along with this growth, the definition of what constitutes a “wiki” has broadened since its introduction in 1995. Consider the example of WikiLeaks, where editable content would defeat the purpose of the site.

  • Enterprise Integration Patterns Introduction
    Enterprise Integration Patterns Gregor Hohpe Sr. Architect, ThoughtWorks [email protected] July 23, 2002 Introduction Integration of applications and business processes is a top priority for many enterprises today. Requirements for improved customer service or self-service, rapidly changing business environments and support for mergers and acquisitions are major drivers for increased integration between existing “stovepipe” systems. Very few new business applications are being developed or deployed without a major focus on integration, essentially making integratability a defining quality of enterprise applications. Many different tools and technologies are available in the marketplace to address the inevitable complexities of integrating disparate systems. Enterprise Application Integration (EAI) tool suites offer proprietary messaging mechanisms, enriched with powerful tools for metadata management, visual editing of data transformations and a series of adapters for various popular business applications. Newer technologies such as the JMS specification and Web Services standards have intensified the focus on integration technologies and best practices. Architecting an integration solution is a complex task. There are many conflicting drivers and even more possible ‘right’ solutions. Whether the architecture was in fact a good choice usually is not known until many months or even years later, when inevitable changes and additions put the original architecture to test. There is no cookbook for enterprise integration solutions. Most integration vendors provide methodologies and best practices, but these instructions tend to be very much geared towards the vendor-provided tool set and often lack treatment of the bigger picture, including underlying guidelines and principles. As a result, successful enterprise integration architects tend to be few and far in between and have usually acquired their knowledge the hard way.

  • From a Pattern Language to a Field of Centers and Beyond Patterns and Centers, Innovation, Improvisation, and Creativity
    From a Pattern Language to a Field of Centers and Beyond Patterns and Centers, Innovation, Improvisation, and Creativity Hajo Neis Illustration 1: University of Oregon in Portland Downtown Urban Campus The Campus is located in downtown Portland in adapted old warehouse buildings, and was first designed in the Oregon pattern language method with the principles of pat- terns and user participation. The White Stag building facilities are open since 2009. 144 Hajo Neis INTRODUCTION What we call now the ›overall pattern language approach‹ in architecture, urban design, and planning has grown from its original principle of ›pattern and pat- tern language‹ into a large and solid body of theory and professional work. To- day, pattern theory and practice includes a large number of principles, methods, techniques and practical project applications in which patterns themselves play a specific part within this larger body of knowledge. Not only has the pattern lan- guage approach grown in its original area of architecture, but it has also (though less triumphantly than silently) expanded into a large number of other disciplines and fields, in particular computer and software science, education, biology, com- munity psychology, and numerous practical fields. Nevertheless, we first have to acknowledge that the pattern approach originally started with a single principle almost 50 years ago, the principle of pattern and pattern language that gave the name to this school of thought and practical professional project work. In this article we want to trace some of the theoretical and practical develop- ment of the pattern method and its realization in practical projects. We want to explore how challenges and opportunities resulted in the adaptation of the pattern language method into various forms of pattern project formats and formulations including ›pattern language‹ and ›project language.‹ We want to look at various forms of innovations and techniques that deal with theoretical improvements as well as the necessities of adaptation for practical cases and projects.

Pattern Languages in HCI: A Critical Review Andy Dearden Sheffield Hallam University Janet Finlay Leeds Metropolitan University ABSTRACT This article presents a critical review of patterns and pattern languages in hu- man–computer interaction (HCI). In recent years, patterns and pattern languages have received considerable attention in HCI for their potential as a means for de- veloping and communicating information and knowledge to support good de- sign. This review examines the background to patterns and pattern languages in HCI, and seeks to locate pattern languages in relation to other approaches to in- teraction design. The review explores four key issues: What is a pattern? What is a pattern language? How are patterns and pattern languages used? and How are values reflected in the pattern-based approach to design? Following on from the review, a future research agenda is proposed for patterns and pattern languages in HCI. Andy Dearden is an interaction designer with an interest in knowledge sharing and communication in software development. He is a senior lecturer in the Com- munication and Computing Research Centre at Sheffield Hallam University.

The process of creating pattern language grasps and discloses discoveries and findings in campus planning, enabling all the users to pursue their ideal campus. The patterns that were shaped can be categorized into three domains; architecture and landscape, educational programs, and internal activities for campus planning. This paper also adopts the practical example of the campus planning process of a residential education and research facility, called Student Build Campus SBC), an initiative that allows people to create their own campus at Keio University, Shonan Fujisawa Campus (SFC) in Japan. Our research is based on architect Christopher Alexander’s studies on the Oregon Experiment and the construction of Eishin Campus School.
