We test whether S-wave/P-wave amplitude ratio data can improve the computed focal mechanisms of small earthquakes, using events from two southern California aftershock sequences. The observed S/P ratios are generally consistent with the expected mechanisms, implying that S/P ratios can in fact be useful in constraining the focal mechanisms of small events. However, we also find that noise in th...

most previous laboratory studies of local scour at bridge abutments were performed in rectangular channels in which the distributions of flow velocity and bed shear stress were considered uniform in the transverse direction. in reality however, bridge abutments are usually located in the floodplain zone of rivers where velocity and shear stress distributions are directly affected by the lat...

Management sometimes exploits the quest of shareholders for higher return on equity capital, by taking advantage of accounting rules gaps or violating them. The Beneish earnings detection manipulation model, is an attempt to reveal such illegal or at least unethical practices. Evidence regarding the use of “creative” accounting practices, based on that model, during the massive equity fund rais...

We examine capital structure changes to investigate the impact of SFAS No. 13 on lessees. While this accounting standard essentially rearranged capital lease disclosures (from footnotes to the balance sheet), mandated capitalization substantially altered key accounting ratios. Our results document a systematic substitution from capital leases to operating leases and nonlease sources of financin...

Corporation financial analysis is crucial for accounting research, including background and environment, revenue profit, different kinds of ratios. This paper will analyze Corn Products International, a corn refining ingredient companies.

Abstract We use a large repeated cross-section of properties to estimate a selection model of the supply of owner-occupied and rental housing. We find that physical characteristics and unobserved quality and not location are important for selection. We interpret this as strong evidence in favor of contracting frictions in the rental market relating to maintenance and modification of physical ho...

Discrete-time survival data with time-varying covariates are often encountered in practice. One such example is bankruptcy studies where the status of each firm is available on a yearly basis. Moreover, these studies often use financial and accounting based ratios to predict bankruptcy. These ratios are also yearly measures and hence are time-varying. In this paper, we propose a new survival tr...
