The Cost of Empowerment: Multiple Sources of Women’s Debt in Rural India
Poor women borrow from multiple sources. This study examines whether the source of debt matters for women’s role in household financial decisions. Drawing on a household survey from rural Tamil Nadu, we categorise women’s loans along the lines of accessibility and formality into ‘planned loans’ and ‘instant loans’. We find that ‘instant loans’ support women’s bargaining power in various types of household financial decisions, whereas ‘planned loans’ have no impact. This surprising result is better understood when the nature of ‘instant loans’ is examined – these are frequently usurious, involve coercive enforcement methods and are considered socially debasing. Hence women who use them perform a convenient role for their households and in return gain some negotiating power
Weed abundance is positively correlated with native plant diversity in grasslands of southern Australia
Published: June 1, 2017Weeds are commonly considered a threat to biodiversity, yet interactions between native and exotic species in grasslands are poorly understood and reported results vary depending on the spatial scale of study, the factors controlled for and the response variables analysed. We tested whether weed presence and abundance is related to declines in biodiversity in Australian grasslands. We employed existing field data from 241 plots along a disturbance gradient and correlated species richness, cover and Shannon diversity for natives and exot- ics, controlling for seasonal rainfall, climatic gradients and nutrient status. We found no neg- ative relationships in terms of emergent diversity metrics and occupation of space, indeed, many positive relationships were revealed. When split by land-use, differences were found along the disturbance gradient. In high-moderately disturbed grasslands associated with land-uses such as cropping and modified pastures, positive associations were enhanced. Tolerance and facilitation mechanisms may be involved, such as complementary roles through different life history strategies: the exotic flora was dominated mainly by annual grasses and herbs whereas the native flora represented more diverse growth-forms with a higher proportion of perennials. The positive relationships existing between native and exotic plant species in high-moderately disturbed grasslands of South Australia are most likely due to facilitation through different strategies in occupation of space given that the effect of habitat suitability was controlled for by including environmental and disturbance fac- tors. Consequently, although particular weeds may negatively impact biodiversity, this can- not be generalised and management focusing on general weed eradication in grasslands might be ineffectual.Irene MartÃn-Forés, Greg R.

3-dimensional Rules for Finite-Temperature Loops
We present simple diagrammatic rules to write down Euclidean n-point
functions at finite temperature directly in terms of 3-dimensional momentum
integrals, without ever performing a single Matsubara sum. The rules can be
understood as describing the interaction of the external particles with those
of the thermal bath.Comment: 12 pages, 4 figures, to appear in Physics Letters

Australian tertiary learning and teaching scholarship and research 2007-2012
Research into Higher Education is strongly supported in Australia by journals and conferences. Teaching and learning awards, projects and programmes in Australia have gained a significantly larger profile over the last five years thanks, in part, to an imaginative and supportive environment fostered by the federal government through the Australian Learning and Teaching Council (ALTC) and now the Office for Learning and Teaching (OLT)
