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...

Although much research has been conducted on employeesf extra-role behaviors (ERBs), the topic of how newcomers to an organization engage in ERBs remains relatively underexplored. Following social cognitive theory, we develop a dynamic model of newcomersf helping and voice as two types of ERBs....

This paper examines the effect of the change of state shares in a state-owned enterprise (SOE) on the efficiency of the whole society and the payoff of the government. This issue is addressed by setting up a mixed oligopolistic competition model and dividing the analysis into two cases: closed...

Based on the relational perspective of work, we examine the role of job autonomy, social skill, and employee status as factors related to employee job crafting. We found that job autonomy and social skill both directly and interactively influenced job crafting for part-time employees in Japan....

type="main" <title type="main">ABSTRACT</title> <p>In this paper, we consider political interaction in a mixed oligopoly by characterizing how a subsidy is endogenously determined through the bargaining process between firms and politicians. We discuss how the nature of the political equilibrium changes with the type of...</p>

According to the 1998-2008 Henan Statistic Yearbook, Grey Forecasting Model and Time Series Model are used to forecast the carrying capacity of cultivated land in Henan Province. According to the contradiction between limited carrying capacity of cultivated land and the growth of population and...

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...
