Cash Holdings and Firm Performance in the Restaurant Industry

This study explores the link between cash holdings and performance outcomes in public restaurant companies in the United States, leveraging the critical role played by the industry context. We hypothesize that cash holdings have positive associations with both short-term and long-term firm performance in the restaurant industry. Our empirical analyses, based on fixed-effect regression models that control for all time-invariant variables, reveal that holding cash can improve performance in the restaurant industry, in support of our hypotheses

Legal Environment Changes and Firm Value: Evidence From the 1999 SGI Case

The 1999 Silicon Graphics International (SGI) case reduced litigation risks and allowed for discretion in financial statements, resulting in a decrease in the expected losses associated with litigation. In this paper, we explore this new legislative environment and examine the pathways underlying the impact of changes to the legal environment on firm value. Accordingly, this study visualizes how these changes can enhance the value of a firm. In addition, this paper reveals how managers react to the legal changes in financial reporting practices

A Point Crack Source Location Method without Velocity Information in Anisotropic Plates

Locating cracks in a solid object using acoustic emission (AE) is useful both for detecting defects during safety monitoring and for basic laboratory studies of fractures. We developed an acoustic source location (ASL) method without the use of velocity information with AE in anisotropics plates, such as carbon fiber-reinforced polymers. Assuming that the propagation velocity of an unknown elastic wave is constant in anisotropic materials, the objective function to be minimized is defined based on the elliptic wavefront shape-based technique. The objective function is minimized using an iterative method, such as the gradient descent method. As a result of the numerical experiments and PLB testing on a carbon fiber-reinforced polymer plate, the method is accurate within 5% and is stable against noise
