Developing countries around the world are expanding hydropower to meet growing energy demand. In the Brazilian Amazon, >200 dams are planned over the next 30 years, and questions about the impacts of current and future hydropower in this globally important watershed remain unanswered. In this context, we applied a hydrologic indicator method to quantify how existing Amazon dams have altered the...

Previous research has extensively studied individual components of Parkinson’s by studying the disease but thus far does not address the comprehensive impacts and obstacles of life with Parkinson’s. The common experiences of Parkinson’s can offer insight as to how provide better care by addressing multiple domains in a person’s life. This hypothetical case study highlights commonalities shared ...

Information systems are increasingly dependent on highly distributed architectures that include multiple dependencies. Even basic attacks like script-kiddies have drastic effects on target systems as they easily spread through existing dependencies. Unless intrusion effects are accurately assessed, response systems will still be blinded when selecting optimal responses. In fact, using only resp...

This study investigates the market value impacts of IT-enabled supply chain systems using event study method. The authors examine abnormal stock returns to investments in IT-enabled SCM systems announced by 346 firms from 2001 to 2004, and find significant, positive abnormal returns for two, three, and five day periods surrounding the event date. Further, the authors employ organizational integ...

The paper addresses rigid body dynamic simulation of mechanical systems with frictional contacts. It is well known that the use of Coulomb's law of friction with the principles of classical rigid body dynamics introduces mathematical inconsistencies. Speciically, the initial value problem may have no solutions or more than one solution. We show that a suitable lumped model of compliance in the ...

Stressors associated with human activities interact in complex ways to affect marine ecosystems, yet we lack spatially explicit assessments of cumulative impacts on ecologically and economically key components such as marine predators. Here we develop a metric of cumulative utilization and impact (CUI) on marine predators by combining electronic tracking data of eight protected predator species...

The research results presented in this paper were obtained as part of the joint CSIRO-NASA Ageless Aerospace Vehicle (AAV) project. We describe the underlying principles, methodology, and preliminary results of modelling and simulating a multi-cellular sensor and communication network in a dynamic decentralised setting, motivated by a self-monitoring, self-repairing AAV. Such networks are expec...

Watershed management consists of multifunctional activities to manage and address the increasing water resource problems. Ever increasing water demand and rapidly depleting water resources, it has become necessary to develop the adaptation options to recharge groundwater resources. A watershed is a special kind of Common Pool Resources (CPRs); an area is defined by hydrological linkages where o...

High temperature anomalies have recently been shown to have adverse impacts on multiple health and socio-economic outcomes. A well established literature on the impacts of early life stress on life-long human capital accumulation has led us to hypothesize that high temperature anomalies can have long-term impacts on economic productivity. Using data on historical weather and the earnings, place...

Apart from elevated glucose, triglyceride and cholesterol, elevated levels of serum free-fatty acid (FFA) are observed in diabetic patients. Increased FFA load can cause multiple dysregulation which are collectively known as lipotoxicity. Impacts of FFA induced lipotoxicity were evaluated on various cellular responses of metabolism and stress in skeletal muscle myotubes. Under lipotoxicity, oxi...
