Curating Inclusive Cities: Melbourne as Case Study
Tammy Wong HULBERT 서울대학교 환경대학원 2020 環境論叢 Vol.66 No.-
In this era of disrupted public engagement, this paper aims to discuss the underlying principles behind the research framework of ‘Curating Inclusive Cities’, to contribute towards creative pedagogies of community design. Research under this framework focuses on the development of action research based collaborative artistic projects, enacting a model of socially engaged urban curatorial practices to encourage public participation and provide a platform for the care of marginalised voices. The outcomes actively connects these voices to the greater urban public sphere and take the form of artistic projects in public spaces, galleries, museums and virtual spaces to support social connectivity, participatory citizenship, community resilience and the rights of marginalised communities in globalising cities. As an artist, curator and academic, the research occurs in place-based community contexts, driven by an underlying methodology focusing on an expanded notion of space, Thirdspace (Soja 1996 & 2007) ‘spatiality-historicality-sociality’ which considers imagined future spaces and the uneven distribution of social justice in relation to urban communities.
Relative Availability of Iron in Mined Humic Substances for Weanling Pigs

Humic substances include several biological active and inactive compounds that are commonly used for improving soil fertility. Use of humic substances in swine diets is a novel concept. Humic substances contain 8,700 mg/kg of iron but its bioavailability is unknown. This study was conducted to test the bioavailability of iron in humic substances for nursery pigs. One hundred twenty five pigs (Newsham, Colorado Springs, CO) were not given supplemental iron while nursing for 21 d. Pigs were weaned on d 21 and allotted to one of five treatments (four control treatments with different levels of supplemented iron; 0, 30, 70 and 88 mg/kg from ${FeSO}_4$ and one treatment with 70 mg/kg iron from humic substances). Pigs were fed diets for 5 wk ad libitum and water was accessible freely. Body weight and feed intake were measured weekly. Blood samples were taken from pigs on d 28 to measure the number of red blood cells and hemoglobin concentration. Pigs fed a diet with the humic substances grew faster (p<0.05) during the first week postweaning, but performance was not different during the entire 5 wk period. Feed intake and gain/feed were the same among treatments. The slope ratio technique was used to estimate relative iron bioavailability. The concentration of blood hemoglobin did not respond to dietary iron levels using this model. However, the number of red blood cells (106/$\mu$l) was modeled by 4.438+0.017${\times}$ 'ron (mg/kg) from ${FeSO}_4$'0.012${\times}$'ron (mg/kg) from the humic substances' Based on the comparison between the slopes (0.012 from humic substances and 0.017 from ${FeSO}_4$), iron in humic substances was 71% as available as the iron in ${FeSO}_4$. The slopes for dietary feed intake of ${FeSO}_4$ and the iron in humic substances did not differ (p>0.05). Humic substances can replace ${FeSO}_4$ as an alternative iron source for pigs at 71% relative bioavailability.
