Choosing the financial supply is one of the most important decisions for providing optimal structure that can be effective for firm value and stocks market of companies. Therefore, marketing as one of the abilities of the firm can be effective on firm function. The purpose of this research is studying the role of marketing intensity on the relation of financial leverage and firm function in Com...

The impact of financial leverage on firm investment is one of the most important issues in corporate finance. Debt overhang reduces the incentives of shareholder–management coalition in controlling the firm to invest in positive net-present-value investment opportunities. On the other hand, firms without debt in their financial structure face with a new problem known as over-investment. T...

For many natural systems there is an advantage in their simulating on a computer. In this article, a way how to determine the influence of the predator-prey simulation’s parameters on the model’s behaviour based on the leverage points is examined. An investigation whether it is possible to sort the parameters according to the importance and if it is possible to automate the process to a certain...

The presence of clusters in a data set is sometimes due to the existence of certain relations among the measured variables which vary depending on some hidden factors. In these cases, observations could be grouped in a natural way around linear and nonlinear structures and, thus, the problem of doing robust clustering around linear affine subspaces has recently been tackled through the minimiza...

1 Dario Nardi, University of California Los Angeles, Program in Computing, Math Sciences 6363, Los Angeles, CA 90095 [email protected] Abstract—Systems concepts like non-linearity and feedback are relevant in many fields, but interactive software to demonstrate these concepts are uncommon. Three mini-applications are discussed. These applications are relatively simple in programming and desi...

New Zealand has a poor rate of immunisation in comparison to other OECD countries. Immunisation is a major public health issue as it is one of the most cost-effective health interventions. However, high immunisation rates are required to realise the full benefit of immunisation programmes. In this paper we use Systems Thinking to identify principal dynamics that underlie immunisation system and...
