Homelessness, Social Work, Social Policy and the Print Media in Australian Cities

Homelessness is a significant social problem worldwide. This paper describes an Australian study that examined print media representations of homelessness and social work, social policy and social work responses to homelessness in three Australian cities. The research included a content analysis of seven Australian newspapers and semi-structured interviews with 39 social workers employed in the field of homelessness in Adelaide, Melbourne and Sydney. The detailed results of these studies have been published separately elsewhere. This paper reports on how discourses in the print media, social policy and social work practice co-exist in constructing homelessness as a particular social problem, influencing social work responses to homelessness. The research found that individualism is central to many dominant discourses evident in the print media, social policy and social work practice, and that social work is practiced within unequal power relations embedded in organisational contexts.

Understanding the Other’s “Understanding” of Violence: Legitimacy, Recognition, and the Challenge of Dealing with the Past in Divided Societies

Post-conflict societies which have achieved a cessation of violence and embarked on a political conflict transformation process cannot in the long-term avoid a process of dealing with the past. Case studies of South Africa and Northern Ireland confirm this normative claim, showing that within the post-war society as a whole a social consensus on how to “understand” and “recognize” the use of violence that occurred during the conflict is necessary: understanding the other’s “understanding” of violence. A mutual understanding must be reached that both sides fought a campaign that was just and legitimate from their own perspective. The morality of the “other’s violence” has to be recognized.

United we stand, divided we fall: a meta-analysis of experiments on clonal integration and its relationship to invasiveness

Fragmentation and vegetative regeneration from small fragments may contribute to population expansion, dispersal and establishment of new populations of introduced plants. However, no study has systematically tested whether a high capacity of vegetative regeneration is associated with a high degree of invasiveness. For small single-node fragments, the presence of internodes may increase regeneration capacity because internodes may store carbohydrates and proteins that can be used for regeneration. We conducted an experiment with 39 stoloniferous plant species to examine the regeneration capacity of small, single-node fragments with or without attached stolon internodes. We asked (1) whether the presence of stolon internodes increases regeneration from single-node fragments, (2) whether regeneration capacity differs between native and introduced species in China, and (3) whether regeneration capacity is positively associated with plant invasiveness at a regional scale (within China) and at a global scale. Most species could regenerate from single-node fragments, and the presence of internodes increased regeneration rate and subsequent growth and/or asexual reproduction. Regeneration capacity varied greatly among species, but showed no relationship to invasiveness, either in China or globally. High regeneration capacity from small fragments may contribute to performance of clonal plants in general, but it does not appear to explain differences in invasiveness among stoloniferous clonal species.

Locational policies in secondary capital cities: constructing a dynamic framework

Capital cities that are not the economic centers of their nations – so-called secondary capital cities (SSCs) – tend to be overlooked in the field of political science. Consequentially, there is a lack of research and resulting theory describing their local economy and their public policies. This paper analyzes how SCCs try to develop and position themselves through the formulation of locational policies. By linking three different theoretical strands – the Regional Innovation System (RIS) approach, the concept of locational policies, and the regime perspective – this paper aims for constructing a framework to study the economic and political dynamics in SCCs.

Theorizing positioning strategies of secondary capital cities

Capital cities that are not the economic centers of their nations – so-called secondary capital cities (SSCs) – tend to be overlooked in the field of political science. Consequentially, there is a lack of research and resulting theory describing their political economy. This paper proposes a comparative research framework which analyzes how external pressures are influencing the relevant policy makers in the process of (re)positioning the SCC.

Oxygenated polycyclic aromatic hydrocarbons and azaarenes in urban soils: A comparison of a tropical city (Bangkok) with two temperate cities (Bratislava and Gothenburg)

Environmental conditions in the tropics favor the formation of polar polycyclic aromatic compound (polar PACs, such as oxygenated PAHs [OPAHs] and azaarenes [AZAs]), but little is known about these hazardous compounds in tropical soils. The objectives of this work were to determine (i) the level of contamination of soils (0–5 and 5–10 cm layers) from the tropical metropolis of Bangkok (Thailand) with OPAHs and AZAs and (ii) the influence of urban emission sources and soil properties on the distribution of PACs. We hypothesized that the higher solar insolation and microbial activity in the tropics than in the temperate zone will lead to enhanced secondary formation of OPAHs. Hence, OPAH to related parent-PAH ratios will be higher in the tropical soils of Bangkok than in temperate soils of Bratislava and Gothenburg. The concentrations of ∑15OPAHs (range: 12–269 ng g−1) and ∑4AZAs (0.1–31 ng g−1) measured in soils of Bangkok were lower than those in several cities of the industrialized temperate zone. The ∑15OPAHs (r = 0.86, p < 0.01) and ∑4AZAs (r = 0.67, p < 0.01) correlated significantly with those of ∑20PAHs highlighting similar sources and related fate. The octanol–water partition coefficient did not explain the transport to the subsoil, indicating soil mixing as the reason for the polar PAC load of the lower soil layer. Data on PAC concentrations in soils of Bratislava and Gothenburg were taken from published literature. The individual OPAH to parent-PAH ratios in soils of Bangkok were mostly higher than those of Bratislava and Gothenburg (e.g. 9-fluorenone/fluorene concentration ratio was 12.2 ± 6.7, 5.6 ± 2.4, and 0.7 ± 02 in Bangkok, Bratislava and Gothenburg soils, respectively) supporting the view that tropical environmental conditions and higher microbial activity likely lead to higher OPAH to parent-PAH ratios in tropical than in temperate soils.

Applying the Fuzzy Analytical Hierarchy Process in Cognitive Cities

This paper introduces a mobile application (app) as the first part of an interactive framework. The framework enhances the inter-action between cities and their citizens, introducing the Fuzzy Analytical Hierarchy Process (FAHP) as a potential information acquisition method to improve existing citizen management en-deavors for cognitive cities. Citizen management is enhanced by advanced visualization using Fuzzy Cognitive Maps (FCM). The presented app takes fuzziness into account in the constant inter-action and continuous development of communication between cities or between certain of their entities (e.g., the tax authority) and their citizens. A transportation use case is implemented for didactical reasons.

Enhancing multidirectional communication for cognitive cities

This paper presents the technical background and functionality of a meta-application (meta-app) for cognitive cities. This app enhances communication and thereby facilitates e-governance. This paper focuses on a user-centered implementation of the Fuzzy Analytical Hierarchy Process (FAHP) by presenting its technical specifications in relation with cognitive cities. For didactical reasons, a use case from the user perspective is included. Finally the findings are summed up and future work is presented
