It is recognized that international water sector development work has issues with a lack of sustained positive outcomes. A large driver of this outcome is how NGOs work with communities to implement and then manage water services. Many NGOs tend to focus their efforts on improving their reach and organisational growth by continually engaging in new projects. This behaviour is largely driven by ...

The introduction of good faith bargaining in Western Australia: Policy origins and implications for collective bargaining Michael Gillan and Donella Caspersz University of Western Australia The Australian Industrial Relations Commission ruled in 2003 that there was no legal duty on parties to bargain in ‘good faith’. In Western Australia, the Gallop Labor Government has introduced good faith ba...

We have conducted a multiscale analysis of system behavior for improvement of infection control in and among hospitals, other care facilities and their relationships to community settings. Our analysis identifies key leverage points for intervention to improve the quality of healthcare systems. In particular, it reveals intervention points that are not currently being addressed. While today the...

The paper develops a system dynamics simulation model to understand the dynamics of immunisation with the aim of aiding decision making process by proposing policies that would enhance immunisation utilization. The model is designed with the intent to show how particular variables influence immunisation demand and coverage rather than predict immunisation coverage rates. The paper applies syste...

This poster presents two GPU implementations of normalized mutual information (NMI) for a two-step image registration used in version 1.0 of the Photogrammetric Registration of Imagery from Manned and Unmanned Systems (PRIMUS) pipeline [1]. This fully-automated, sensor-agnostic application enables the precise geolocation of aerial and orbital imagery, a fundamental building block for accurate g...

Crowdsourcing is an increasingly popular phenomenon where companies solicit the help of the public in helping accomplish some of the activities commonly performed by employees or contractors. These activities can range from solving scientific problems that baffle the in-house experts to repetitive and boring tasks that are deemed too mundane for the employees. Other activities include content g...

This paper investigates the link between the optimal level of nonfinancial firms’ leverage and macroeconomic uncertainty. We develop a structural model of a firm’s value maximization problem that predicts that as macroeconomic uncertainty increases the firm will decrease its optimal level of borrowing. We test this proposition using a panel of non–financial US firms drawn from the COMPUSTAT qua...

We consider the long memory and leverage properties of a model for the conditional variance V 2 t of an observable stationary sequence Xt, where V 2 t is the square of an inhomogeneous linear combination of Xs, s < t, with square summable weights bj . This model, which we call linear ARCH (LARCH), specializes, when V 2 t depends only on Xt−1, to the asymmetric ARCH model of Engle (1990), and, w...

This paper proposes the new concept of stochastic leverage in stochastic volatility models. Stochastic leverage refers to a stochastic process which replaces the classical constant correlation parameter between the asset return and the stochastic volatility process. We provide a systematic treatment of stochastic leverage and propose to model the stochastic leverage effect explicitly, e.g. by m...

An active isolator achieving both high isolation and low insertion loss at 2.45 GHz is proposed. The based on an asymmetric coupler designed to leverage the gain reverse of amplifier coupling coefficients between input output coupler. are enhanced by using coefficients, power level with optimal can be determined for a target specification. increases handling capability proposed that has coeffic...
