Robert Morris University is a private, coeducational university located in a suburb of Pittsburgh, Pennsylvania, United States. The school was founded in 1921. It enrolls more than 4,000 undergraduates and more than 1,000 graduate students and offers more than 60 bachelor's degree programs and more than 20 master's and doctoral programs. Most students are from the Pittsburgh area, while 17 percent of freshmen in 2014 are from outside Pennsylvania.Robert Morris University is named after Robert Morris, a signer of the Declaration of Independence and financier of the American Revolution. It is not affiliated with Robert Morris University-Illinois. Wikipedia.

This paper introduces an implicit high-order Galerkin finite element Runge-Kutta algorithm for efficient computational investigations of shock structures. The algorithm induces no spatial-discretization artificial diffusion, relies on cubic and higher-degree elements for an accurate resolution of the steep shock gradients, uses an implicit time integration for swift convergence to steady states, and employs original Neumann-type outlet boundary conditions in the form of generalized Rankine-Hugoniot conditions on normal stress and balance of heat flux and deviatoric-stress work per unit time. The formulation automatically calculates the spatial extent of the shock and employs the single non-dimensional (0,1) computational domain for the determination of any shock structure. Since it is implicit, the algorithm rapidly generates steady shock structures, in at most 150 time steps for any upstream Mach number considered in this study. The finite element discretization is shown to be asymptotically convergent under progressive grid refinements, in respect of both the H0 and H1 error norms, with an H0 accuracy order as high as 6 and reduction of the discretization error to the round-off-error threshold of 1×10-9 with just 420 computational cells and 5th-degree elements. For upstream Mach numbers in the range 1.05≤M≤10.0, the computational results satisfy the Rankine-Hugoniot conditions and reflect independently published Navier-Stokes results. © 2010 Elsevier Inc.

The basic concepts of complexity/chaos theories allows an organisation to focus on the ability of people to self-organise to handle problems and changes in the organisation; if control is relinquished and autonomy is spread to all employees. The goal of this paper is to inspect how different organisations are reacting to the recent economic crisis perhaps, while looking at their decisions through a chaotic/complexity theoretical viewpoint. The companies chosen represent a relative wide range of service organisations in the Pittsburgh, PA metropolitan area that allow for contrasting comparisons, from a large global power management company, Eaton Corporation, a large sporting goods company, Dick's Sporting Goods, and a small independent grocery store chain, McGinnis Sisters Specialty Food Stores. To understand the basis for the present case study, a description what constitutes chaos theory in relationship to the companies studied, or what being on the edge of chaos means, and provide an overview of their current financial crisis as it relates to the operations in the chosen organisations, followed by a discussion of the practical applications of lessons learned from the case studies.

In this research the testing of a hybrid Neural Networks-GARCH model for volatility forecast is performed in three Latin-American stock exchange indexes from Brazil, Chile and Mexico. A detail of the methodology and application of the volatility forecast of financial series using a hybrid artificial Neural Network model are presented. The results demonstrate that the ANN models can improve the forecasting performance of the GARCH models when studied in the three Latin-American markets and it is shown that the results are robust and consistent for different ANN specifications and different volatility measures. © 2013 Elsevier Ltd.

For an overall effective strategy, companies must think about the long term based on the factors that help them avoid making frequent, costly changes to their strategy. Operational effectiveness in terms of quality assurance, coupled with consistent output, may be the method to survive the current financial crisis. This paper will inspect and document, from an operational management viewpoint, how three unique service-orientated organisations comprising both service and manufacturing sectors (an electrical utility, an automobile parts supplier and a cable/information provider) manage quality, specifically within the unique functions of the organisation: human resources, investor relations and finance. These aspects will be viewed through the lens of the recent financial crisis that has hit the global marketplace, beginning with the general situation, and then managing quality company-wide, managing quality within specific financial business functions, and the impact of the current credit crisis in terms of managing quality. The first section of this paper will examine the concepts of organisation quality via Six Sigma Programme (SSP) development and lean manufacturing principles as a precursor to the case studies in order to lay down the foundations for comparative analysis among the firms studied.

CSR and green-based strategies have become important concepts in dealing with firms' stakeholders. Two relatively large firms that were selected to study were Pittsburgh-based, namely PNC, a major financial service provider, and CONSOL, the leading diversified fuel producer in the Eastern USA. By pursuing leaner and greener operations, management at these companies has developed a better corporate image and higher profit via promoting triple-line reporting and financial responsibilities. Improved environmental, health, and safety performance can help with plant productivity and also increase sales and market share. It is extremely important to stay in line with regulations, including hazardous waste and pollutants. The present study focuses on these green processes via stakeholder legitimacy and interest detection. Strategic alignment with green initiatives can result in significant and sustainable results in companies studied as they have shown that they are adaptive and align their people and the planet with their profits.
