Western Illinois University is a public university located in Macomb, Illinois, United States. It was founded in 1899 as Western Illinois State Normal School. Like many similar institutions of the time, Western Illinois State Normal School focused on teacher training for its relatively small body of students. As the normal school grew, it became Western Illinois State Teachers College. Today, Western Illinois University is composed of two campuses that provide a wide range of academic programs. While the main campus is in Macomb, Western Illinois University-Quad Cities is in Moline, Illinois. Wikipedia.


Nanomaterials are at the leading edge of the rapidly developing field of nanotechnology. Nanomaterials such as magnetic iron oxides and magnetic gold-coated iron oxides nanoparticles exhibit unusual optical, thermal, chemical, and physical properties, due to a combination of high-energy surface atoms compared to bulk solids. Their low toxicity, biocompatibility, and established protocols of synthesis have resulted in a tremendous upsurge of interest, and their applications as special biomolecule carriers via a stable immobilization process show promise as sensitive detection tools. This review provides a comprehensive analysis of new synthetic routes, characterization methodologies, and functionalization protocols of magnetic and gold-coated magnetic iron oxides nanoparticles. Applications of these materials as scaffolds for biosensing and detection are also discussed. © 2011 Bentham Science Publishers Ltd.

While e-recruiting has been widely adopted as one of the most successful e-business applications, it constitutes an under-researched area in e-business research. This study reviews the integration issues in e-recruiting and presents an e-recruiting integration decision model. The benefits of the investment in e-recruiting process integration are discussed in comparison to separate e-recruiting investments. We show that the optimal investment in the e-recruiting process integration results in a lower total cost than the separate e-recruiting investments. In addition, in light of the widely practiced resource constrained investments, we present the method of Lagrange multipliers which is used to find the optimal investment under a budget constraint. © 2010 Elsevier B.V.

In conventional conoscopic interference patterns of optically anisotropic materials the isochromatic interference fringes are inherently masked by the dark isogyres. We prove that the isochromatic fringes can be directly visualized by spinning the crossed linear polarizer and analyzer, regardless of the polarization state of the incident light. This simple method completely eliminates the isogyres and reveals the whole isochromatic fringes without the need of any additional optical elements or calculations. The system works at any wavelength that the linear polarizer permits. The validity of this method is demonstrated by observing the interference patterns of an LiNbO3 electro-optic crystal under different external electric fields. © 2012 Optical Society of America.

The existing studies conceptualize a direct relationship between acquired labor flexibility and plant performance, producing inconsistent empirical results, which makes the topic ripe for further inquiry. We believe acquiring labor flexibility is not sufficient; its implementation is an important intervening step when companies have to tackle accompanying technical and behavioral side effects of labor flexibility. In this paper, we develop and test a theoretical model in which we introduce an intervening variable to capture the implementation of labor flexibility. In addition, evolving human resource management practices that promote acquisition of labor flexibility are also examined in our model. Case studies in ten printed circuit board plants validated our model. Subsequently, survey data collected from 74 PCB plants was analyzed using Partial Least Squares method. Supporting the proposed model, the results show that the impact of acquired labor flexibility on plant performance is not direct but experienced through the sophistication of labor flexibility implementation exercised by the plant. Our findings also suggested that plants that emphasized process-focused training, provided greater job-rotation training, and designed positive reward structures, acquired higher labor flexibility. © 2012 Elsevier B.V.

Annual Review of Phytopathology | Year: 2011

Endophytes are microorganisms that live within plant tissues without causing symptoms of disease. They are important components of plant microbiomes. Endophytes interact with, and overlap in function with, other core microbial groups that colonize plant tissues, e.g., mycorrhizal fungi, pathogens, epiphytes, and saprotrophs. Some fungal endophytes affect plant growth and plant responses to pathogens, herbivores, and environmental change; others produce useful or interesting secondary metabolites. Here, we focus on new techniques and approaches that can provide an integrative understanding of the role of fungal endophytes in the plant microbiome. Clavicipitaceous endophytes of grasses are not considered because they have unique properties distinct from other endophytes. Hidden from view and often overlooked, endophytes are emerging as their diversity, importance for plant growth and survival, and interactions with other organisms are revealed. © 2011 by Annual Reviews.
