Incentives for enterprise engagement in Vietnam: Private and social enterprise engagement in water and sanitation for the poor
Enterprise in WASH is a joint research project led by the Institute for Sustainable Futures (ISF) at the University of Technology, Sydney, which investigates the role of private and social enterprises in the delivery of water, sanitation and hygiene (WASH) services for the poor. In particular, the research aims to support civil society organisations (CSOs) engaged at the interface of public sector, private and social enterprise, and civil society

City Sanitation planning through a political economy lens
© 2019 Water Alternatives Association. While citywide sanitation planning is perceived to be an enabler of coordinated improvements in sanitation services for developing countries, intended outcomes have often been elusive. In order to illustrate how political economy, chosen planning approaches, and ideas about change and development have acted as determinants of outcomes, this paper draws on three case study countries that took qualitatively different approaches to sanitation planning - Indonesia, the Philippines and Malaysia. The analysis found that the assumptions informing the planning methods were often not valid, which then undermined the potential for successful implementation. Based on the analysis, the paper argues that urban sanitation planning and implementation in developing countries needs to be transformed to reduce the emphasis on comprehensiveness and instead emphasise flexibility, a learning orientation and strategically chosen incentives. This approach demands tighter cycles of planning and action, direct testing of assumptions, and an in-depth understanding of the local- and national-level political economy and the links between them. It requires innovation to be enabled, with funding mechanisms that focus on outcome rather than input. In this way it would be possible to shift away from the typical emphasis on prescriptive procedural planning steps and towards delivery of the much-needed improved sanitation outcomes
Are we doing the right thing? Critical questioning for city sanitation planning
Our aim is to provoke practitioners, policy makers and development agencies to reflect on their approaches to city sanitation planning and the assumptions that underlie them. The document is not intended as a critique, and it does not recommend a particular planning approach. Nor does it add to existing stocks of guidance materials on how to develop sanitation plans (e.g. Sanitation 21, WHO Sanitation Safety Planning Guide 2015, Community-Led Urban Environmental Sanitation Planning (CLUES), guidance for City Sanitation Strategies (SSK) in Indonesia and City Sanitation Plans (CSPs) in India etc). Rather, our premise is that raising awareness of underlying assumptions in sanitation planning may lead to better targeted approaches to sanitation planning, if and when those assumptions are shown not to match realities

Modelling water diffusion in plasticizers: development and optimization of a force field for 2,4-dinitroethylbenzene and 2,4,6-trinitroethylbenzene
A classical all-atom force field has been developed for 2,4,6-trinitroethylbenzene and 2,4-dinitroethylbenzene and applied in molecular dynamics simulations of the two pure and two mixed plasticizer systems. Bonding parameters and partial charges were derived through electronic and geometry optimization of the single molecules. The other required parameters were derived from values already available in the literature for generic nitro aromatic compounds, which were adjusted to reproduce to a high level of accuracy the densities of 2,4-dinitroethylbenzene, 2,4,6-trinitroethylbenzene and the energetic plasticizers K10 and R8002. This force field has been applied to both K10 and R8002, which when used as plasticizers form an energetic binder with nitrocellulose. Nitrocellulose decomposes in storage, under varying conditions, but in particular where it may become increasingly dry. Following the derivation of the force field, we have therefore applied it to calculate water diffusion coefficients for each of the different materials at 298 K and 338 K, thereby providing a starting point for understanding water behaviour in a nitrocellulose binder
