This book includes contributions from various authors who are interested in students’ feedback regarding how technology has impacted on their educational experience. This book …


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 …


Computational Thinking In A Game Design Course, Amber Settle Oct 2011

Computational Thinking In A Game Design Course, Amber Settle

Amber Settle

As a part of an NSF-funded project to enhance computational thinking in undergraduate general education courses, activities and assessments were developed for a game design course taught at DePaul University. The focus of the course is on game analysis and design, but the course textbook uses an approach that is heavily grounded in computational thinking principles. We describe the course activities and assignments and discuss an initial assessment of those materials. Our results show that there is a gap in difficulty between several of the activities and indicate that the materials developed help students to better learn the computational thinking …


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 …


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

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

George H Baker

The Commission to Assess the Threat to the United States from Electromagnetic Pulse Attack has provided a compelling case for protecting civilian infrastructure against the effects of EMP. As with protecting infrastructure against any hazard, it will be important to take a risk-based priority approach for EMP, recognizing that it is fiscally impracticable to protect everything. In this regard, EMP is particularly challenging in that it interferes with electrical and electronic data, control, transmission, and communication systems organic to nearly all infrastructures in a simultaneous and wide-scale manner. And, for nuclear burst altitudes of 100s of kilometers, the exposed geography …

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 …


How Do Environmental And Natural Resource Economics Texts Deal With The Simple Model Of The Intertemporal Allocation Of A Nonrenewable Resource, Robert Main Jul 2011

How Do Environmental And Natural Resource Economics Texts Deal With The Simple Model Of The Intertemporal Allocation Of A Nonrenewable Resource, Robert Main

Robert S. Main

Textbooks in Environmental and Natural Resource Economics invariably deal with the problem of allocating a non-renewable resource over time. The simplest version of that problem is the case of a resource that is to be allocated over two periods. The resource has a constant Marginal Extraction Cost (MEC). Most textbooks treat this case before moving on to more complex and realistic cases. This paper suggests the results that should be emphasized and the method that should be used to arrive at those results. It also points out the possible confusions that should be avoided. Finally, it examines how several well-known …


Bayesian Mixtures Of Autoregressive Models, Sally Wood, Ori Rosen, Robert Kohn Feb 2011

Bayesian Mixtures Of Autoregressive Models, Sally Wood, Ori Rosen, Robert Kohn

Sally Wood

In this paper we propose a class of time-domain models for analyzing possibly nonstationary time series. This class of models is formed as a mixture of time series models, whose mixing weights are a function of time. We consider specifically mixtures of autoregressive models with a common but unknown lag. The model parameters, including the number of mixture components, are estimated via Markov chain Monte Carlo methods. The methodology is illustrated with simulated and real data.


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.

Content-Based Retrieval For Trademark Registration, Jian Kang Wu, Chiam Prong Lam, Babu M. Mehtre, Yunjun Gao, Arcot Desai Narasimhalu

Arcot Desai NARASIMHALU

With ever increasing number of registered trademarks, the task of trademark office is becoming increasingly difficult to ensure the uniqueness of all trademarks registered. Trademarks are complex patterns consisting of various image and text patterns, called device-mark and word-in-mark respectively. Due to the diversity and complexity of image patterns occurring in trademarks, due to multi-lingual word-in-mark, there is no very successful computerized operating trademark registration system. We have tackled key technical issues: multiple feature extraction methods to capture the shape, similarity of multi-lingual word-in-mark, matching device mark interpretation using fuzzy thesaurus, and fusion of multiple feature measures for conflict trademark …

A Framework For The Integration Of Expert Systems With Multimedia Technologies, Arcot Desai Narasimhalu

Arcot Desai NARASIMHALU

Expert system (ES) technology allows the capture and replication of expertise in an application domain. So far, the type of data that is used by an expert system for its reasoning process remains primarily alphanumeric. Image, graphics, and other dynamic data such as voice and video are part of an emerging technology generally termed multimedia technology. This article highlights the critical issues in building a successful application combining the two technologies. Based on these critical issues, it also provides a framework for the integration of multimedia technology with expert systems technology.

Management Of Technology Deployed In Service Innovations, Arcot Desai Narasimhalu

Arcot Desai NARASIMHALU

Services form a major portion of the GDP of several nations, especially that of the first world nations. These nations also experience high cost of providing services of different kinds. This has resulted in the displacement of non-customer facing services to countries that can offer them at lower prices. Nations have to be concerned about sustaining their economies even as such off-shoring of services continue to grow. It is therefore important to understand how countries can create those service innovations that will help them retain the growth trajectory of their economies. We believe that the different types of service innovations …

A Method For Monetizing Technology Innovations, Arcot Desai Narasimhalu Jan 2011

A Method For Monetizing Technology Innovations, Arcot Desai Narasimhalu

Arcot Desai NARASIMHALU

Technology innovations from most universities and research institutes are generally created with no clear path to commercialization in mind. This is largely due to the culture in academic institutions and research institutes whose mission it is to explore the creation of innovations that promise long term benefits. This culture of academic freedom leads to a stockpile of technology innovations at their technology transfer offices (TTOs). These offices are often in a dilemma on how best to monetize the technology innovations that are in their custody. While there have been many social science research methodology based studies on this subject under …
