Exploring sustainable urbanism in masterplanned developments: : a collective case study of slippage between principles, policies, and practices

© 2020 Taylor & Francis. This is an Accepted Manuscript of an article published by Taylor & Francis in Journal of Urbanism: International Research on Placemaking and Urban Sustainability on 22nd July 2020, available online: https://doi.org/10.1080/17549175.2020.1793802.This article is concerned with masterplan implementation and with exploring, via recourse to case studies, slippages between masterplanning principles, policies, and practices. Framed by a growing body of sustainable urbanism literature we analyse evidence from five masterplanned communities in the UK and Australia to comparatively explore how some key theoretical principles are translated into placemaking in inner urban, suburban, outer urban and semi-rural contexts. We observe varying degrees of disjuncture between masterplanning principles and the urban form envisioned by, and realized through, actual masterplanning proposals and implementation. We postulate that various degrees of slippage at each stage from proposals to practices have occurred which can affect capacity to meet principles of sustainable urbanism. Analysis of the five cases demonstrates where some potential “tripping-up” points lie in the masterplanning process, hinting at broader impediments to delivering masterplanning that is more closely aligned to sustainable urbanism principles in future.Peer reviewedFinal Accepted Versio

An interactive web-based Pseudomonas aeruginosa genome database: discovery of new genes, pathways and structures

Using the complete genome sequence of Pseudomonas aeruginosa PAO1, sequenced by the Pseudomonas Genome Project (ftp://ftp.pseudomonas.com/data/pacontigs.121599), a genome database (http://pseudomonas.bit.uq.edu.au/) has been developed containing information on more than 95% of all ORFs in Pseudomonas aeruginosa. The database is searchable by a variety of means, including gene name, position, keyword, sequence similarity and Pfam domain. Automated and manual annotation, nucleotide and peptide sequences, Pfam and SMART domains (where available), Medline and GenBank links and a scrollable, graphical representation of the surrounding genomic landscape are available for each ORF. Using the database has revealed, among other things, that P. aeruginosa contains four chemotaxis systems, two novel general secretion pathways, at least three loci encoding F17-like thin fimbriae, six novel filamentous haemagglutinin-like genes, a number of unusual composite genetic loci related to vgr/Rhs elements in Escherichia coli, a number of fix-like genes encoding a micro-oxic respiration system, novel biosynthetic pathways and 38 genes containing domains of unknown function (DUF1/DUF2). It is anticipated that this database will be a useful bioinformatic tool for the Pseudomonas community that will continue to evolve
