RESUMEN
We examine the extent to which residential relocation within and between tenure types is associated with changes in mental health. We focus on four types of housing transition - rent-to-own, own-to-rent, own-to-own, and rent-to-rent - using Australian and UK panel data sets from 2001 to 2017. In both countries, transitions into homeownership and moves away from the mortgaged edges toward the unburdened mainstream of outright ownership are positively associated with mental health. On the other hand, shifts by mortgagors towards more precarious positions on the edges of ownership precipitate dips in mental health when there is exposure to high levels of payment and investment risks. Clearly, residential moves can both alleviate and introduce different kinds of risks that affect affordability. Moreover, tenure transitions have impacts on mental health beyond the impacts of payment and investment risks. However, we observe some cross-national differences in findings. In Australia, loss of homeownership has a negative impact on mental health that outweighs the mental health impacts of attaining ownership. In the UK, these findings are reversed. Acute housing affordability problems following moves in Australia, but not in the UK, are a significant driver of mental health outcomes. These differences have institutional explanations.
RESUMEN
A measure of soil P status in agricultural soils is generally required for assisting with prediction of potential P loss from agricultural catchments and assessing risk for water quality. The objectives of this paper are twofold: (i) investigating the soil P status, distribution, and variability, both spatially and with soil depth, of two different first-order catchments; and (ii) determining variation in soil P concentration in relation to catchment topography (quantified as the "topographic index") and critical source areas (CSAs). The soil P measurements showed large spatial variability, not only between fields and land uses, but also within individual fields and in part was thought to be strongly influenced by areas where cattle tended to congregate and areas where manure was most commonly spread. Topographic index alone was not related to the distribution of soil P, and does not seem to provide an adequate indicator for CSAs in the study catchments. However, CSAs may be used in conjunction with soil P data for help in determining a more "effective" catchment soil P status. The difficulties in defining CSAs a priori, particularly for modeling and prediction purposes, however, suggest that other more "integrated" measures of catchment soil P status, such as baseflow P concentrations or streambed sediment P concentrations, might be more useful. Since observed soil P distribution is variable and is also difficult to relate to nationally available soil P data, any assessment of soil P status for determining risk of P loss is uncertain and problematic, given other catchment physicochemical characteristics and the sampling strategy employed.
