The Role of Middle Range Publications in the Development of Engineering Knowledge

This paper explores the role of publications in the development of engineering knowledge. Previous studies of scientific and technical publications tend to assume that engineers are like scientists in their use of scientific journals as a means of communicating new technical knowledge. But science differs from technology and we should not expect scientists and engineers to use the same sources of knowledge. We contend that previous studies of publications have been flawed because they ignore other forms of publication more suited to the communication of technical and engineering knowledge. This paper argues that technologists use "middle range" publications to exchange knowledge and explore implications of their technological experiences. By providing more visual images, experience-based reports and background information on technologies and products, middle range publications better reflect the ways in which engineers think and work. They allow for visual conversations and support visual communities. The paper provides a detailed exploration of the role of middle range publications and suggests a framework for future research on patterns of publication by technologists and engineers.engineering knowledge, engineering and design organisations, construction, scientific publications, technical publications, innovation studies

Design Performance Measurement in the Construction Sector: A Pilot Study

This paper examines the role and deployment of design performance measurements (DPMs) in the construction industry, focusing on the consulting engineering sector, the design 'heart' of construction. Compared with manufacturing, there has been very little research on the use of DPMs in construction, and firms often struggle to find appropriate performance indicators. Using results from structured questionnaires, the paper shows that the few DPMs which do exist focus mainly on cost. Other measures are needed to address quality, innovative performance and client satisfaction. In contrast to manufacturing, DPMs in construction also need to address the project-based, multi-firm and non-routine nature of construction design, as well as the separation of design from manufacturing, build and operation. Interviews and workshops with industrialists were used to identify recent DPM practices in construction and combine these with lessons from other sectors. The resulting DPM tools provide guidance on how to: (a) integrate design into wider business processes in construction; (b) identify key design indicators, at both project and firm level; and (c) use DPMs to provide a balanced scorecard for design performance.performance indicators, design integration, design indicators, construction industry

How open is innovation? A retrospective and ideas forward

This paper sheds fresh light on our 2010 paper How Open Is Innovation by taking into consideration notable developments in innovation over the last decade. The original paper developed four types of openness: sourcing, acquiring, selling, and revealing. Reflecting on important technological, organizational, and societal changes in the past decade, we highlight how these changes prompt novel questions for open innovation. While the core features of the original framework still stands, there are many new questions that have emerged in recent years. We end by charting a path for future research that emphasizes opportunities, costs and tradeoffs between different modes of open innovation, the need to better understand the nature of data, new organizational designs and legal instruments, and multilevel aspects and relationships that affect the extent and nature of openness

This is the Piece that Everyone Here Has Come to Experience: The Challenges to Copyright of John Cage’s 4’33”

Framed within the broader context of law's engagement with modernism, this paper offers an argument in defence of copyright protection of John Cage's 4′33″ as a ‘musical work’ under the Copyright, Designs and Patents Act 1988. This argument approaches the issues involved analytically and contextually. In doing so, it draws on both legal and non-legal sources. Throughout the paper, the underlying question remains as to whether Cage's 4′33″ really is – or is not – a challenge to law (and to music)

Five rules for managing large, complex projects

Large-scale, long-term projects are notoriously difficult to manage. But recent research on megaprojects — defined as projects costing more than $1 billion — reveals five lessons that can help executives manage any big, complex project more effectively

A social-ecological-technological systems framework for urban ecosystem services

As rates of urbanization and climatic change soar, decision-makers are increasingly challenged to provide innovative solutions that simultaneously address climate change impacts and risks and inclusively ensure quality of life for urban residents. Cities have turned to nature-based solutions to help address these challenges. Nature-based solutions, through the provision of ecosystem services, can yield numerous benefits for people and address multiple challenges simultaneously. Yet, efforts to mainstream nature-based solutions are impaired by the complexity of the interacting social, ecological, and technological dimensions of urban systems. This complexity must be understood and managed to ensure ecosystem-service provisioning is effective, equitable, and resilient. Here, we provide a social-ecological-technological system (SETS) framework that builds on decades of urban ecosystem services research to better understand four core challenges associated with urban nature-based solutions: multi-functionality, systemic valuation, scale mismatch of ecosystem services, and inequity and injustice. The framework illustrates the importance of coordinating natural, technological, and socio-economic systems when designing, planning, and managing urban nature-based solutions to enable optimal social-ecological outcomes

TGF-β1 Induces an Age-Dependent Inflammation of Nerve Ganglia and Fibroplasia in the Prostate Gland Stroma of a Novel Transgenic Mouse

TGF-β1 is overexpressed in wound repair and in most proliferative disorders including benign prostatic hyperplasia and prostate cancer. The stromal microenvironment at these sites is reactive and typified by altered phenotype, matrix deposition, inflammatory responses, and alterations in nerve density and biology. TGF-β1 is known to modulate several stromal responses; however there are few transgenic models to study its integrated biology. To address the actions of TGF-β1 in prostate disorders, we targeted expression of an epitope tagged and constitutively active TGF-β1 via the enhanced probasin promoter to the murine prostate gland epithelium. Transgenic mice developed age-dependent lesions leading to severe, yet focal attenuation of epithelium, and a discontinuous basal lamina. These changes were associated with elevated fibroplasia and frequency of collagenous micronodules in collapsed acini, along with an induced inflammation in nerve ganglia and small vessels. Elevated recruitment of CD115+ myeloid cells but not mature macrophages was observed in nerve ganglia, also in an age-dependent manner. Similar phenotypic changes were observed using a human prostate epithelium tissue recombination xenograft model, where epithelial cells engineered to overexpress TGF-β1 induced fibrosis and altered matrix deposition concurrent with inflammation in the stromal compartment. Together, these data suggest that elevated TGF-β1 expression induces a fibroplasia stromal response associated with breach of epithelial wall structure and inflammatory involvement of nerve ganglia and vessels. The novel findings of ganglia and vessel inflammation associated with formation of collagenous micronodules in collapsed acini is important as each of these are observed in human prostate carcinoma and may play a role in disease progression

A transient presence: black visitors and sojourners in Imperial Germany, 1884-1914

The onset of German colonial rule in Africa brought increasing numbers of Black men and women to Germany. Pre-1914 the vast majority of these Africans can best be described as visitors or sojourners and the Black population as a whole was a transient one. This makes recovering their presence in the archival record exceptionally difficult and it is not surprising that the existing historiography almost exclusively focuses on individual biographies of well documented lives. Through utilising a number of newly digitised archival materials, particularly the Hamburg Passenger Lists, this article draws upon a database with information on 1092 individuals from sub-Saharan Africa who spent time in Germany over the period 1884-1914 in order to add considerable bread and depth to our understanding of the Black presence as a whole. It provides increasing empirical detail about the make-up and character of this fluid population - where visitors came from, why they came to Germany, their age on arrival - as well as more accurate detail on the temporal and, to a lesser extent, spatial distribution of visitors
