This note shows that, for the combinatorial market goods defined by Wellman et al. (2001), there may not exist an optimal allocation that is in equilibrium. Moreover, this result holds even if the value of each processed job is independent of its completion time. The proposed algorithm for...

This paper addresses two important issues that may affect the operations efficiency in the recycling industry. First, the industry contains many small-scale and inefficient recycling firms, especially in developing countries. Second, the output from recycling a waste product often yields...

We consider the problem of scheduling a set of equal-processing-time jobs with arbitrary job sizes on a set of batch machines with different capacities. A job can only be assigned to a machine whose capacity is not smaller than the size of the job. Our goal is to minimize the schedule length...

This study investigates the role of strategic orientations of small- and medium-sized enterprises (SMEs) in an emerging market, namely Dubai in the United Arab Emirates. It uses the business-level typology of Miles and Snow (prospector, analyzer, and defender) to examine the effect of strategic...

Instant messenger (IM) is one of the most popular Internet applications all over the world.This paper examines the pricing problem of IM based on two-sided market model. IM serves as a two-sided platform, which gets both Internet users and advertisers on board. This paper concludes that IM...

Cellulosic biofuels have been proposed to replace part of traditional liquid transportation fuels. Cellulosic biomass is the feedstock in cellulosic biofuel manufacturing. Costs associated with collection and transportation of cellulosic biomass account for more than 80 percent of the feedstock...

Recent developments in the leadership literature call for research that emphasizes the role of the follower as well as that of emotion in the leader–member exchange (LMX). In response to these calls, this research examines the relationship between subordinate emotional masking and LMX quality,...

With the portable Fourier Transform Infrared Spectroscopy (FTIR), the reflectance spectra of soil samples with different moisture content are measured in laboratory for expounding the characteristic of radiation in the thermal infrared part of the spectrum with different soil moisture content. A...

Four model-based State of Charge (SOC) estimation methods for lithium-ion (Li-ion) batteries are studied and evaluated in this paper. Different from existing literatures, this work evaluates different aspects of the SOC estimation, such as the estimation error distribution, the estimation rise...

The relationship between human agency and health is an important yet under-researched topic. This study uses a life course perspective to examine how human agency (measured by voluntariness, migratory reasons, and planning) and timing (measured by age at immigration) affect mental health...
