Options in Corporate Finance Management

Abstract

Although there are many opinions critical of options, especially after the 2008 scandal, they are becoming increasingly popular in Poland again. Therefore, issues connected with options are not only the subject of interest in academic circles again but also arouse interest of economic entities, allowing enterprises to assess a variety of action strategies. Those instruments enable planning safeguards to protect against various negative future scenarios. Hence, it comes as no surprise that there has been an increase in the number and variety of enterprises that have accepted options as a way to plan for their future. The article provides a brief presentation of options. It also describes one of their pricing methods. Light of the foregoing has been hypothesized that 'valuation of options using mathematical calculators using the binomial model is an effective tool for supporting management positions in futures instruments’.

Kaizen as a Method of Management Improvement in Small Production Companies

Abstract

„Quality is not everything but everything is nothing without quality”. The famous quotation from K. Ishikawa brings to our attention the fact that nowadays quality is one of strategic concepts from the point of view of functioning of companies, especially production-oriented ones. The lack of quality often eliminates a product from the basket of potential further choices. That means that quality is a prerequisite in the contemporary, highly competitive and saturated market. In order to ensure quality, enterprises introduce various concepts and methods to support quality management. They include, among others, the kaizen philosophy, which allows to minimize unnecessary actions (losses). It is especially recommended to small firms as an inexpensive method assuring high quality of products because they are constantly improved, which, in turn, guarantees maintaining a high position among competitors. This article aims to introduce the concept of kaizen by describing how it works and considering whether it can be successful in Polish companies.

Professional Evaluation. Application of the PageRank Algorithm in Employee Rating

Abstract

Appraisal is a tool used by both management and employees to attain their goals. Properly carried out employee performance appraisal allows to monitor the employee's actions and provides information on the level of his or her performance. Feedback in the form of appraisal motivates the employee to work more effectively and productively. Appraisal also enables to shape the personnel policy – it allows to chart employee career paths and determine training needs of an organization. For appraisal, however, to fulfil the attributed role, it needs to be carried out in a professional manner.

It describes, among others, determinants, criteria as well as selected methods and techniques of appraisal. An interesting point can be the use of the PageRank algorithm which can be a good solution for rating employees.

Initial Study on Implementation of the Low-Frequency Wave Markers for the Purpose of Diagnostic Tests’ Performance and Neurofeedback Therapy

Abstract

The paper focuses on automation of signal processing, which also considers analysis of biomedical data, such as EEG. The results of the study prove that this enables a better understanding of signal changes and makes it possible to address some specific disturbances. It also makes it possible to describe the relevant changes in signals mathematically and helps to create markers of various brain disorders. This paper presents the study at the initial stage and focuses on the mathematical markers of concentration disorders associated with Theta waves. The presented markers presented are based on Welch’s periodograms. The obtained results are very promising and further studies aimed at refining them are currently being carried out.
