In Australia, the female prisoner population is expanding, with the majority also being mothers of dependent children. Research has demonstrated that witnessing the arrest of a family member, particularly a parent, can have both an immediate and long-term impact on children's well-being. Yet, little is known about what causes these outcomes and how children are responded to by police during the arrest process. The aim of this study is to investigate incarcerated primary carer mothers' perspectives on their arrest circumstances, its impact on their children, and police responses to their children during the arrest process. This study draws on secondary data from 36 primary carer mothers arrested in Victoria, which were originally gathered for an Australian Research Council-funded project. Results show that in around one-half of cases children are present at their mothers' arrest. The location and time of the arrest can mediate children's involvement in the arrest scene. Overall, police do not respond well to these children, with discussion between police officers and the mothers about suitable care for children occurring in less than two-thirds of cases. It can be concluded that children's needs are not fully addressed at the arrest process. More child-sensitive arrest practices are recommended.

This is a conference paper. ; Housing stock models predict long term changes in the stock to inform national policy. They operate with a set of reference dwellings representing the national stock, which are changed in response to different scenarios. However, national level models do not consider geographical variations (urban location/rural surroundings, index of multiple deprivation score, etc.), so cannot aid in targeting improvement measures (eg: insulation, microgeneration, etc.) locally. A geographically varying model can identify which measures are most appropriate in a particular location. In this paper a method has been designed and implemented using information at LSOA level (c. 700 dwellings each) to introduce geographical variation for a model of the North East of England. It has been tested against DECC meter data and over 80% of LSOAs are predicted to within ±25% of DECC's data. The model allows localised policies and interventions to be tested, and is principally of interest to local government and energy efficiency initiatives.

Abstract
Background
Colloid-facilitated phosphorus (P) transport is recognized as an important pathway for the loss of soil P in agricultural systems; however, information regarding soil aggregate-associated colloidal P (Pcoll) is lacking. To elucidate the effects of aggregate size on the potential loss of Pcoll in agricultural systems, soils (0–20 cm depth) from six land-use types were sampled in the Zhejiang Province in the Yangtze River Delta region, China. The aggregate size fractions (2–8 mm, 0.26–2 mm, 0.053–0.26 mm and < 0.053 mm) were separated using the wet sieving method. Colloidal P and other soil parameters in aggregates were analyzed.

Results
Our study demonstrated that 0.26–2 mm small macroaggregates had the highest total P (TP) content. In acidic soils, the highest Pcoll content was observed in the 0.26- to 2-mm-sized aggregates, while the lowest was reported in the < 0.053 mm (silt + clay)-sized particles, the opposite of that revealed in alkaline and neutral soils. Paddy soils contained less Pcoll than other land-use types. The proportion of Pcoll in total dissolved P (TDP) was dominated by < 0.053 mm (silt + clay)-sized particles. Aggregate size strongly influenced the loss potential of Pcoll in paddy soils, where Pcoll contributed up to 83% TDP in the silt + clay-sized particles. The Pcoll content was positively correlated with TP, Al, Fe, and the mean weight diameter. Aggregate-associated total carbon (TC), total nitrogen (TN), C/P, and C/N had significant negative effects on the contribution of Pcoll to potential soil P loss. The Pcoll content of the aggregates was controlled by the aggregate-associated TP and Al content, as well as the soil pH value. The potential loss of Pcoll from aggregates was controlled by its organic matter content.

Conclusion
We concluded that management practices that increase soil aggregate stability or its organic carbon content will limit Pcoll loss in agricultural systems.
