Design for the Right to the Smart City in More-than-Human Worlds

Environmental concerns have driven an interest in sustainable smart cities, through the monitoring and optimisation of networked infrastructure processes. At the same time, there are concerns about who these interventions and services are for, and who benefits. HCI researchers and designers interested in civic life have started to call for the democratisation of urban space through resistance and political action to challenge state and corporate claims. This paper aims to add to the growing body of critical and civic led smart city literature in HCI by leveraging concepts from the environmental humanities about more than human worlds, as a way to shift understandings within HCI of smart cities away from the exceptional and human centered, towards a more inclusive understanding that incorporates and designs for other others and other species. We illustrate through a case study that involved codesigning Internet of Things with urban agricultural communities, possibilities for creating more environmentally and socially just smart cities

An evaluation of biotic ligand models predicting acute copper toxicity to Daphnia magna in wastewater effluent

This is the author's accepted manuscript. The final published article is available from the link below. Copyright @ 2010 SETAC.The toxicity of Cu to Daphnia magna was investigated in a series of 48-h immobilization assays in effluents from four wastewater treatment works. The assay results were compared with median effective concentration (EC50) forecasts produced by the HydroQual biotic ligand model (BLM), the refined D. magna BLM, and a modified BLM that was constructed by integrating the refined D. magna biotic ligand characterization with the Windermere humic aqueous model (WHAM) VI geochemical speciation model, which also accommodated additional effluent characteristics as model inputs. The results demonstrated that all the BLMs were capable of predicting toxicity by within a factor of two, and that the modified BLM produced the most accurate toxicity forecasts. The refined D. magna BLM offered the most robust assessment of toxicity in that it was not reliant on the inclusion of effluent characteristics or optimization of the dissolved organic carbon active fraction to produce forecasts that were accurate by within a factor of two. The results also suggested that the biotic ligand stability constant for Na may be a poor approximation of the mechanisms governing the influence of Na where concentrations exceed the range within which the biotic ligand stability constant value had been determined. These findings support the use of BLMs for the establishment of site-specific water quality standards in waters that contain a substantial amount of wastewater effluent, but reinforces the need for regulators to scrutinize the composition of models, their thermodynamic and biotic ligand parameters, and the limitations of those parameters.EPSRC and Severn Trent Water

In or Out? Experiential Learning and Three Consequences of Communicating Group Identity

Group identity is intimately tied with self identity. Yet, people often understand their identity as individual without appreciation for the role others play in their identity. Based on social identity theory this article highlights the role that group identity plays in self identity and explores three consequences of this association. Case studies present first-hand experience with the consequences of communicating group identity. These case studies also demonstrate the value of a specific class project undertaken to provide students with a meaningful understanding of these issues

Geographic profiling in Nazi Berlin: fact and fiction

Geographic profiling uses the locations of connected crime sites to make inferences about the probable location of the offender’s ‘anchor point’ (usually a home, but sometimes a workplace). We show how the basic ideas of the method were used in a Gestapo investigation that formed the basis of a classic German novel about domestic resistance to the Nazis during the Second World War. We use modern techniques to re-analyse this case, and show that these successfully locate the Berlin home address of Otto and Elise Hampel, who had distributed hundreds of anti-Nazi postcards, after analysing just 34 of the 214 incidents that took place before their arrest. Our study provides the first empirical evidence to support the suggestion that analysis of minor terrorism-related acts such as graffiti and theft could be used to help locate terrorist bases before more serious incidents occur

THE ORIGINS OF THE COLD WAR IN SOUTHEAST ASIA: THE CASE OF THE COMMUNIST PARTY OF MALAYA (1948–1960) – A SPECIAL BRANCH PERSPECTIVE

The origins of the Malayan Emergency (1948–1960) have been debated over the years in both the academic world and in the intelligence community. This paper incorporates the contemporaneous views of the Malayan Special Branch that have not been recorded previously. It also examines the role of Lawrence (Lance) Sharkey, the acting Secretary-General of the Australian Communist Party, who was in Singapore en route back to Australia after attending the February 1948 Conferences in Singapore, in allegedly passing instructions to the Communist Party of Malaya (CPM) to revolt against the British colonial government in Malaya. The essay will conclude that there is little evidence of any direct Soviet intervention in the decision made by the CPM to revolt, and it will argue that the decision to resort to armed conflict was made after its failure to establish a Communist People’s Democratic Republic by “open front” activities

13 Reasons Why NOT: Examining Peer Networks and Barriers to Help Seeking

This paper examines mental health perceptions on a college campus, with an emphasis on the importance of peer networks, the barriers to help-seeking behaviors, and the persisting stigma against mental health treatment. The researcher hypothesized that students will report confiding in family, friends, and peers in times of emotional distress, rather than more formal support networks. The study utilized a 13-item survey that examined what barriers students face in seeking help, to whom students turn in times of distress, and if they feel that there is stigma on campus that is a deterrent to formal mental health treatment. The results supported the thesis with the finding that 96% of students reported turning to friends during times of distress, compared to 56% of students who used a formal help network

Probabilistic latent semantic analysis as a potential method for integrating spatial data concepts

In this paper we explore the use of Probabilistic Latent Semantic Analysis (PLSA) as a method for quantifying semantic differences between land cover classes. The results are promising, revealing ‘hidden’ or not easily discernible data concepts. PLSA provides a ‘bottom up’ approach to interoperability problems for users in the face of ‘top down’ solutions provided by formal ontologies. We note the potential for a meta-problem of how to interpret the concepts and the need for further research to reconcile the top-down and bottom-up approaches
