In this paper, we study the traveling umpire problem (TUP), a difficult combinatorial optimization problem that is formulated based on the key issues of Major League Baseball. We introduce an arc-flow model and a set partition model to formulate the problem. Based on these two models, we propose...

Using detailed information on employment trajectory provided by the Longitudinal Survey of Immigrants to Canada (LSIC), this study examines labour market outcomes of recent immigrants in terms of duration of access to the first job in their intended occupation, as determined by a question in the...

This paper applies the panel unit root, heterogeneous panel cointegration and panel-based dynamic OLS to re-investigate the co-movement and relationship between energy consumption and economic growth for 30 provinces in mainland China from 1985 to 2007. The empirical results show that there is a...

We study how gradualism -- increasing required levels ("thresholds") of contributions slowly over time rather than requiring a high level of contribution immediately -- affects individuals' decisions to contribute to a public project. Using a laboratory binary choice minimum-effort coordination...

There is a substantial literature examining coordination in public goods games. We conducted an experiment to explore how varying patterns of thresholds affect the willingness of subjects to contribute to a public good. We had subjects play a multiperiod game where each subject was allocated an...

A trivariate maximum entropy distribution of significant wave height, wind speed and the relative direction is proposed here. In this joint distribution, all the marginal variables follow modified maximum entropy distributions, and they are combined by a correlation coefficient matrix based on...

A series of well-designed thin-film composite (TFC) hollow fiber membranes via dual-layer co-extrusion technology for pressure retarded osmosis (PRO) applications is reported in this work. By controlling the phase inversion process during spinning, we have molecularly engineered hollow fiber...

This paper estimates the availability of agricultural crop residue feedstocks in Canada for cellulosic ethanol production. Canada's major field crops generate 100.6million dry mega grams (Mg) of crops per year while non-forage crops produce 67 million dry Mg, leaving abundant agricultural...
