Residence exchange wanted: A stable residence exchange problem

This paper introduces a special matching problem, the stable residence exchange problem, originated from the need for residence exchange in China. The problem involves families wishing to exchange their residences based on their preferences. The stability of exchange is defined and the problem can be formed as a special case of trading indivisible goods with preferences. The solution method and the properties of the solution are discussed and the factors that may affect the performance of the residence exchange are investigated through computer simulation. Finally, the application considerations are addressed.     

On the measurement of technical efficiency in the public sector

Existing measures of technical inefficiency obtained through linear programming models in the public sector do not properly control for environmental variables that affect production. It will be shown that the consequences of not controlling for these fixed factors are biased estimates of technical efficiency. This paper extends the mathematical programming approach to frontier estimation known as Data Envelopment Analysis to allow for environmental variables. This modified model will be then contrasted with the existing model that purportedly controls for exogeneous factors to measure public sector efficiency with simulated data. The results provide evidence that the existing Data Envelopment Analysis model will overestimate the level of technical inefficiency and that the modified model developed in this paper does a better job controlling for exogenous factors. The modified model is also applied to analyze the technical efficiency of school districts.

Moral Argument in the Public Sphere: The Case of Bosnia

This paper uses a formal content analysis to decide what moral argument looks like in political debate. Does it involve more the abstract arguments and general principles of the philosophers or the devices of the rhetoricians, like ideographs, casuistry, and moral vocabulary? To test this question, we examine the U.S. debate over intervention in Bosnia between 1991 and 1995 as it showed up in the opinion pages of The New York Times, Christian Science Monitor, and The Washington Post.

A major, unexpected finding of the research is support for Appiah's (2010) argument against the New Intuitionists in psychology that outside the laboratory, the major moral work to be done is framing.

Public perceptions on artificial intelligence driven disaster management: Evidence from Sydney,Melbourne and Brisbane

In recent years, artificial intelligence (AI) is being increasingly utilised in disaster management activities. The public is engaged with AI in various ways in these activities. For instance, crowdsourcing applications developed for disaster management to handle the tasks of collecting data through social media platforms, and increasing disaster awareness through serious gaming applications. Nonetheless, there are limited empirical investigations and understanding on public perceptions concerning AI for disaster management. Bridging this knowledge gap is the justification for this paper. The methodological approach adopted involved: Initially, collecting data through an online survey from residents (n = 605) of three major Australian cities; Then, analysis of the data using statistical modelling. The analysis results revealed that: (a) Younger generations have a greater appreciation of opportunities created by AI-driven applications for disaster management; (b) People with tertiary education have a greater understanding of the benefits of AI in managing the pre- and post-disaster phases, and; (c) Public sector administrative and safety workers, who play a vital role in managing disasters, place a greater value on the contributions by AI in disaster management. The study advocates relevant authorities to consider public perceptions in their efforts in integrating AI in disaster management.
