Application of simple prescriptions of technical analysis on the Warsaw Exchange Market (GPW) has been analyzed using several stocks belonging to WIG20 group as examples. Only long positions have been considered. Three well-known technical-analysis indicators of the market have been investigated: the Donchian channels, the Relative Strength Index, and Moving Average Convergence-Divergence indicator. Optimal values of parameters of those indicators have been found by „brute force“ evaluation of (linear) returns. It has been found that trading based on both Donchian channels and Relative Strength Index easily outperform the „buy and hold“ strategy if supplied with optimal values of parameters. However, those optimal values are by now means universal in the sense that they depend on particular stocks, and are functions of time. The optimal management of capital in the stock market strongly depends on the time perspective of trading. Finally, it has been argued that the criticism of technical analysis which is often delivered by academic quantitative financial science is unjustified as based of false premises.
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.
The aim of the article is to draw attention to the importance of employee performance appraisal in the personnel management process and to provide information on the core principles of appraisal. 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.
Collaboration between doctors and patient is a perfect example of a specific kind of collaboration in the organization. Difficulties with establish proper relations between psychiatrists and patients with depressive disorders and schizophrenia is the subject of the paper. The thesis of the work assumes that psychiatrists and patients belong to the totally different “worlds” what is the cause of inability to create proper mutual collaboration between them. In 2009 a questionnaire survey was conducted at public mental hospitals of the Lodz region. Both doctors and patients notice a number of communication barriers and factors hampering the mutual cooperation, at the same time demonstrating the will to agree and cooperate. The proper contact and collaboration affect mental disposition and motivation for the process of recovery from the illness.
Conclusion: To a large extent not only a course of the treatment, but also a correct social functioning of both groups of the patients depends on the quality of the interrelation between them and psychiatrists. It appears, however, that the hierarchy of obstacles of successful therapy is completely different among the doctors and patients

We decided to use the PROMETHEE method to rank selected types of investment funds offered on the Polish market. In our deliberations, we took an interest in the investor with a certain aversion to risk who chooses from among treasury securities or stable growth funds. We took into consideration whole ranking lists made for half-yearly periods from 2010 to 2012 instead of the specific objects pointed by model. We decided to check whether, among investment products of interest to us, there are stable relationships over time arising from their ranking positions that allow to identify regular groups of leaders and outsiders. Moreover, we checked the influence of the fund size measured by the value of its assets on its ranking position.

The area of applying outsourcing that has been raised in this article is accounting outsourcing. The study provides information on the scope of accounting services usually performed outside the enterprise, demonstrates the specificity of these services in Polish conditions, and shows the impact of outsourcing on costs generated by the company.

In Poland, after the economic transformation a lot of fields of business lines required adaptation, also in social security. On last years performed some changes in the insurances.
The sick insurance in the common social insurance has been defined as obligatory for the employees, and voluntary at the request of the person. The cash expenditures for benefits from sick insurance of the contribution charges only the employee insured, also employers incur cost connected with the sickness of employees to pay the remuneration for inability for work.
The unfavorable demographic conditions which determine making the decisions also in the past years, modification of rights and levels of benefits from sick insurance was introduced, which did not reduce, but quite contrary, increased expenses, especially for sick and maternity benefits. It means lack for balancing the sick fund and necessity to search an answer in the foreseeable future to the question whether the level of the contribution should not be reviewed and updated.
The systemic transformation in Poland, aimed, among others, at activating market mechanisms, has resulted in a change in the ownership structure and privatization that has accompanied it. Privatization processes are commonly considered to be principally motivated by an increase in efficiency of the economy based on the assumption that efficiency of private enterprises is higher than that of public sector ones. The main aim of the article is to verify the above hypothesis. An analysis of efficiency of public and private sector enterprises, taking into account their organizational and legal forms, made on the basis of Central Statistical Office information, confirmed the above hypothesis. Private enterprises use their assets better and take advantage of the financial leverage mechanism to a larger extent. It should be emphasized, however, that private enterprises are more adversely affected by economic fluctuations caused by the crisis.
