Risk-Based Critical Infrastructure Priorities For Emp And Solar Storms, George H. Baker Iii Oct 2011

Risk-Based Critical Infrastructure Priorities For Emp And Solar Storms, George H. Baker Iii

George H Baker

Two electromagnetic phenomena have the potential to create continental-scale disasters. The first, nuclear electromagnetic pulse (EMP), results from a nuclear detonation high above the tropopause. The second, a major solar storm, or "solar tsunami" occurs naturally when an intense wave of charged particles from the sun perturbs the earth's magnetic field. Both phenomena can debilitate electrical and electronic systems necessary for the operation of infrastructure systems and services. One reason why a U.S. protection program has yet to be initiated is that policy makers continue to wrestle with the question of where to begin, given the Department of Homeland Security’s …


Issues In Human Capital Development : Lessons For Public Administration And Governance, Deogratias Harorimana Mr Oct 2011

Issues In Human Capital Development : Lessons For Public Administration And Governance, Deogratias Harorimana Mr

Dr Deogratias Harorimana

With few minerals or other natural resources, Rwanda believes that she can still achieve her ambitions by investing in human capital - her unique resource. If this ambition can be achieved, then is this the next role model for international development? We used a case study design and analysis methods to examine development models used elsewhere in recent decades, using both qualitative and quantitative data on Rwanda to establish the comparative advantages in relation to Singapore’s economic development model. The implications for international development are that (1) an effective human capital development strategy should be inclusive enough to respond to …


Recommendations For Australia’S Implementation Of The National Emergency Warning System Using Location-Based Services, Anas Aloudat, Katina Michael, Roba Abbas Sep 2011

Recommendations For Australia’S Implementation Of The National Emergency Warning System Using Location-Based Services, Anas Aloudat, Katina Michael, Roba Abbas

Professor Katina Michael

Mobile alerts, notifications and location-based emergency warning systems are now an established part of mobile government strategies in an increasing number of countries worldwide. In Australia the national emergency warning system (NEWS) was instituted after the tragic Black Saturday Victorian Bushfires of February 2009. In the first phase, NEWS has enabled the provision of public information from the government to the citizen during emergencies anywhere and any time. Moving on from traditional short message service (SMS) notifications and cell broadcasting to more advanced location-based services, this paper provides executive-level recommendations about the viability of location-based mobile phone services in NEWS …

Waldo In The Light Of Austerity And Federal Debt Crisis, Part 2, Jan Kallberg Aug 2011

Waldo In The Light Of Austerity And Federal Debt Crisis, Part 2, Jan Kallberg

Jan Kallberg

Waldo’s predictions about the future for public administration describe five areas that would be problematic in the future: legitimacy, authority, knowledge, control, and confidence. Legitimacy includes not only that the government is legally legitimized but capable and focused on an intention to deliver the “good society.” Authority, according to Waldo, is the ability to implement policy with the acceptance of the people based on rationalism, expectations of public good, ethics, superior knowledge, and institutional contexts. Knowledge is institutional knowledge, the ability to arrange and utilize knowledge within the bureaucracy since coordination is the major challenge in knowledge management. Government has …


Waldo In The Light Of Austerity And Federal Debt Crisis, Part 1, Jan Kallberg Aug 2011

Waldo In The Light Of Austerity And Federal Debt Crisis, Part 1, Jan Kallberg

Jan Kallberg

Dwight Waldo wrote The Enterprise of Public Administration in 1979 looking back on a long and fruitful academic career, but also as a reflection about the future for public administration. Can a 30 year old book still be relevant? You bet. Today, the public sector is increasingly facing fiscal challenges. Federal, state, and local governments throughout the country have major budget deficits followed by austerity measures that undermine the ability to deliver the good life of the future. In this day and age rereading Dwight Waldo’s The Enterprise of Public Administration is an intellectual exercise worth pursuing. Several of Dwight …


Supply Chain Contract Evolution, T. Coltman, K. Bru, N. Perm-Ajchariyawong, T. M. Devinney, G. R. Benito Feb 2011

Supply Chain Contract Evolution, T. Coltman, K. Bru, N. Perm-Ajchariyawong, T. M. Devinney, G. R. Benito

Tim Coltman

This paper draws together theories from organisational and neo-institutional literatures to address the evolution of supply chain contracts. Using a longitudinal case study of the Norwegian State Railways, we examine how firms move through the stages in an inter-organisational process of supply chain contract evolution and how they can cooperate to ensure efficiency and equity in their contractual relationship. The findings suggest that inefficient and inequitable initial contracts can occur in part, because of the cognitive shortcomings in human decision-making processes that reveal themselves early in the arrangement before learning and trust building can accumulate. We then reveal how parties …


Customer Response To Carbon Labelling Of Groceries, Jerome K. Vanclay, John Shortiss, Scott Aulsebrook, Angus M. Gillespie, Ben C. Howell, Rhoda Johanni, Michael J. Maher, Kelly M. Mitchell, Mark D. Stewart, Jim Yates Jan 2011

Customer Response To Carbon Labelling Of Groceries, Jerome K. Vanclay, John Shortiss, Scott Aulsebrook, Angus M. Gillespie, Ben C. Howell, Rhoda Johanni, Michael J. Maher, Kelly M. Mitchell, Mark D. Stewart, Jim Yates

Professor Jerome K Vanclay

Thirty-seven products were labelled to indicate embodied carbon emissions, and sales were recorded over a 3-month period. Green (below average), yellow (near average), and black (above average) footprints indicated carbon emissions embodied in groceries. The overall change in purchasing pattern was small, with black-labelled sales decreasing 6% and green-labelled sales increasing 4% after labelling. However, when green-labelled products were also the cheapest, the shift was more substantial, with a 20% switch from black- to green-label sales. These findings illustrate the potential for labelling to stimulate reductions in carbon emissions.

Innovation Stack - Choosing Innovations For Commercialization, Arcot Desai Narasimhalu

Arcot Desai NARASIMHALU

This paper describes a method for enterprises to order the innovations of interest according to a number of parameters including their own business strategy and core competencies. The method takes into account aspects such as ability to create entry barriers and complementary assets. Enterprises can now use this method to both filter out innovations that may not be of interest to them and then order the short listed or selected innovations according to their attractiveness.

Crossing The Chasm: The Xid Technologies Story, Arcot Desai Narasimhalu, Roberto Mariani

Arcot Desai NARASIMHALU

XID Technologies is a face processing start up company built initially around a disruptive face recognition technology. The technology innovation came from Kent Ridge Digital Labs, a publicly funded software research laboratory in Singapore. Face recognition is the least intrusive and harmless among the various biometric solutions available in the market. The basic approach to human face recognition is to identify a robust feature set that was unique enough to differentiate amongst the many millions of human faces that the system was required to verify. The technology innovation used by XID framed the problem differently and thereby overcame the challenges …

Modelling The Impact Of Personality On Individual Performance Behavior With A Time-Varying Mixture Of Monotonic Random Effects, Sally A. Wood, Edward J. Cripps, Robert E. Wood, John Lau Dec 2010

Modelling The Impact Of Personality On Individual Performance Behavior With A Time-Varying Mixture Of Monotonic Random Effects, Sally A. Wood, Edward J. Cripps, Robert E. Wood, John Lau

Sally Wood

A method is presented for flexibly modelling longitudinal data that provides insight to a central question in psychology theory: the dependency between personality clas- sification and individual performance behavior. Flexibility is achieved by assuming the regression coefficients of random effects models are generated from a time-varying mixture of an unknown but finite number of processes, where the weights attached to the number of processes are parameterised to depend upon an individual’s personality classification. For a given number of mixture components the component processes are constrained distributions and the weights attached to them depend upon time. The method is made robust …

Modeling Multivariate Distributions Using Copulas: Applications In Marketing, Peter J. Danaher, Michael S. Smith Dec 2010

Modeling Multivariate Distributions Using Copulas: Applications In Marketing, Peter J. Danaher, Michael S. Smith

Michael Stanley Smith

In this research we introduce a new class of multivariate probability models to the marketing literature. Known as “copula models”, they have a number of attractive features. First, they permit the combination of any univariate marginal distributions that need not come from the same distributional family. Second, a particular class of copula models, called “elliptical copula”, have the property that they increase in complexity at a much slower rate than existing multivariate probability models as the number of dimensions increase. Third, they are very general, encompassing a number of existing multivariate models, and provide a framework for generating many more. …
