Design thinking for city dashboard development: Recommendations from a study of smart asset management in Sydney,Australia

The city dashboard has become an integral component of smart city asset management systems. It leverages data collected from multiple sources to monitor performance and enable evidence-based decision making. This article investigates the use of a design thinking framework to develop a functional and easy to understand city dashboard. The Smart Social Spaces project is used as a case study to illustrate how design thinking can be employed to develop an asset management dashboard, enabling efficient management of public space and infrastructure. The article profiles the unique collaboration between a local government, a multi-disciplinary team of university academics, and a street furniture designer and manufacturer, all located in Sydney, Australia. We unpack some of the design practice nuances that led this project to receive national awards and international recognition, and most importantly, created a user-friendly system to track and maintain public micro assets. We conclude with lessons learnt and recommendations for dashboard development through a design thinking process.     

Stochastic Efficiency of Bayesian Markov Chain Monte Carlo in Spatial Econometric Models: An Empirical Comparison of Exact Sampling Methods

Spatial econometric specifications pose unique computational challenges to Bayesian analysis, making it difficult to estimate models efficiently. In the literature, the main focus has been on extending Bayesian analysis to increasingly complex spatial models. The stochastic efficiency of commonly used Markov Chain Monte Carlo (MCMC) samplers has received less attention by comparison. Specifically, Bayesian methods to analyze effective sample size and samplers that provide large effective size have not been thoroughly considered in the literature. Thus, we compare three MCMC techniques: the familiar Metropolis‐within‐Gibbs sampling, Slice‐within‐Gibbs sampling, and Hamiltonian Monte Carlo. The latter two methods, while common in other domains, are not as widely encountered in Bayesian spatial econometrics. We assess these methods across four different scenarios in which we estimate the spatial autoregressive parameter in a mixed regressive, spatial autoregressive specification (or, spatial lag model). We find that off‐the‐shelf implementations of the newer high‐yield simulation techniques require significant adaptation to be viable. We further find that the effective sizes are often significantly smaller than nominal sizes. In addition, we find that stopping simulation early may understate posterior credible interval widths when effective sample size is small. More broadly, we suggest that sample information and stopping rules deserve more attention in both applied and basic Bayesian spatial econometric research.     

Single and Multiscale Models of Process Spatial Heterogeneity

Recent work in local spatial modeling has affirmed and broadened interest in multivariate local spatial analysis. Two broad approaches have emerged: Geographically Weighted Regression (GWR) which follows a frequentist perspective and Bayesian Spatially Varying Coefficients models. Although several comparisons between the two approaches exist, recent developments, particularly in GWR, mean that these are incomplete and missing some important axes of comparison. Consequently, there is a need for a more thorough comparison of the two families of local estimators, including recent developments in multiscale variants and their relative performance under controlled conditions. We find that while both types of local models generally perform similarly on a series of criteria, some interesting and important differences exist.     

Empire,Repetition, and Reluctant Subjects: British Home Movies of Kenya, 1928–72

This article examines efforts by a range of British visitors to produce ‘home movies’ or amateur film of Kenya from 1928 to 1972, and attempts by both the British film-makers and Kenyans to navigate and influence this production. By bringing cine-cameras to Kenya to record images to be consumed back in the metropole by family and friends as ‘holiday films’, these British visitors laid bare what a number of historians have identified as the ‘imperial gaze’ that defined both colonial and post-colonial conceptions of Africa. Colonialism’s obsession with ordering and positioning bodies within a projected image of power and control made cinema the perfect vessel for such an exercise, while amateur film, with its often clumsy framing and highly personal interaction between the film-maker and the film subject, grants us unique insight into the sometimes coercive, transactional and forced efforts involved in projecting such an image. The amateur films that sit at the centre of this article, which were produced by British visitors to Kenya both before and after independence, offers us the opportunity to examine the wide range of behaviours of both the film-maker and the filmed which underpinned the production of repetitive imperial image-making in colonial and post-colonial Kenya.     

The importance of difference in the making of transnationality: biographies and networks of the Benedictine mission in Tanganyika (1922–65)

The Missionary Benedictines of Saint Ottilien were the first Roman Catholic mission house in imperial Germany. During the heyday of European imperialisms, colonialisms and Christian missions the monastic community began its engagement in ‘German East Africa’. To enable and promote its proselytization efforts in the imperial colony until the end of the Great War, the Missionary Benedictines had to respond to shifting political conditions and to rearrange their networks as and when required. This orientation became even more pronounced during the renewal of the Benedictine Mission in the British mandated territory of Tanganyika up until the Second Vatican Council and the political independence of Tanzania. From 1922 to 1965 at least 379 members of the Congregation lived and worked in Tanganyika. Their biographies were closely linked to the complex transboundary system of their religious community. This article will portray them as a highly institutionalized group of transnational actors. It argues that to maintain its activities and organizational structures, the leaders of the Benedictine Mission established a dynamic multi-level network connecting a variety of scales, spaces and actors. To ensure its continued existence under constantly changing conditions they constituted a hierarchic system of difference and diversity.
