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...

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...

The World Bank Group (WBG) has adopted a new strategy which sets two ambitious goals of ending extreme poverty and promoting shared prosperity. To operationalize the twin goals, the WBG is developing a more evidence-based and selective country engagement model, the Country Partnership Framework...

From an information systems perspective, the assessment of commercial websites can be assessed objectively or subjectively. From a business point of view, they can be assessed quantitatively or qualitatively. This paper describes taxonomy of website assessment approaches and proposes a...

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...

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...
