Rationale and design of the violence, injury and trauma observatory (VITO)
The establishment of violence and injury observatories elsewhere has been found to reduce the burden within a relatively short period. Currently no integrated system exists in South Africa to provide collated data on violence...

Sovereign credit ratings in the European Union
We present a model-based measure of sovereign credit ratings derived solely from the fiscal position of a country: a forecast of its future debt liabilities, and its potential to use fiscal policy to repay these. We use this...

How the euro crisis evolved and how to avoid another
Vito Polito, Mike Wickens
Mar 01, 2014
This paper argues that the crisis was an outcome of EMU: setting a common monetary policy for countries with different initial inflation rates. The crisis countries were those with high inflation rates which then had negative...

Optimal control of heteroscedastic macroeconomic models
Vito Polito, Peter Spencer
Dec 01, 2016
This paper analyses the implications of heteroscedasticity for optimal macroeconomic policy and welfare. We find that changes in the variance structure driven by exogenous processes like GARCH affect welfare but not the optimal...

Correlates of Balance and Aerobic Indices in Lower-Limb Prostheses Users on Arm Crank Exercise
Gary Guerra, John Smith
Oct 19, 2021
Background: The HUMAC Balance System (HBS) offers valid measurement of balance, and the arm crank exercise test (ACE) is a valid measure of physiological capacity. Neither have been used to evaluate associations between balance...

Quantifying Step Count and Oxygen Consumption with Portable Technology during the 2-Min Walk Test in People with Lower Limb Amputation
John Smith, Gary Guerra
Mar 16, 2021
Step counts and oxygen consumption have yet to be reported during the 2-min walk test (2MWT) test in persons with lower-limb amputations (LLA). The purpose of this study was to determine step counts and oxygen consumption during...

Compensation phenomena for concentration effects via nonlinear elliptic estimates
We study compensation phenomena for fields satisfying both a pointwise and a linear differential constraint. This effect takes the form of nonlinear elliptic estimates, where constraining the values of the field to lie in a cone...
