The goal of a research was to determine the efficiency of foreign direct investments (FDI) in Poland comparing to alternative forms of capital allocation. The analysis of Polish FDI according to economic activity and geographical zone was conducted. In 2000-2012 the inward position of FDI rose significantly due to a surge in equity capital and reinvested earnings as well as in other capital in form of various debt instruments. Generally the rate of return on FDI in Poland was higher than the Polish and US government bond yields that gave an evidence of a higher efficiency of FDI comparing to a low risk financial instruments.

Celem badań było określenie efektywności polskich bezpośrednich inwestycji zagranicznych (BIZ ) w porównaniu z alternatywnymi formami inwestowania kapitału. Przeprowadzono analizę polskich BIZ według rodzaju działalności gospodarczej oraz strefy geograficznej. W latach 2000-2012 stan zobowiązań z tytułu BIZ znacząco wzrósł na skutek zwiększenia wartości zobowiązań z tytułu udziałów kapitałowych i reinwestowanych zysków, a także pozostałego kapitału w formie instrumentów dłużnych. Stopa zwrotu z BIZ w Polsce była wyższa niż rentowność polskich i amerykańskich obligacji skarbowych, co potwierdzało wyższą efektywność BIZ w porównaniu z instrumentami finansowymi o niższym poziomie ryzyka.

Na podstawie danych producentów porównano koszty zakupu i eksploatacji trzech wybranych modeli brykieciarek do słomy. Obliczono czas zwrotu inwestycji przy założeniu dysponowania własnym materiałem wsadowym i robocizną. Analiza może być przydatna dla rolników planujących zakup brykieciarki na własne potrzeby.

Cost of purchase and using of three chosen models of briqueting machines for straw on the basisc of 3 different producers have been compared. Returning time of investment has been calculated to assume that producer has own stock material and labour cost at his disposal. The analysis can be useful for farmers planning to purchase briquetting machines for personal use.

Individual marking is necessary for determining various elements of species ecology, but toe-clipping — a method frequently used in amphibian studies, is recently being questioned. Three water bodies (of 0.3 to 1.5 ha in size) used by common Bufo bufo for breeding, located within a large city (Warsaw, Central Poland), were chosen for the study. Captured toads had Passive Integrated Transponders (PIT) subcutaneously implanted under laboratory conditions. Marked toads were searched in consecutive breeding seasons. The recapture rate of males in particular ponds was up to 13% — much lower than in other studies carried out in non-urban habitats. 77% of re-trapped individuals were found in the next season after tagging. There were no differences in the frequency of re-trapped individuals in relation to the toe-clipping treatment, as some marked individuals had part of the toe (two phalanges) clipped for skelotochronological analyses. An individual from this group was observed to have regenerated the clipped toe after one year. We did not find any indication of better body condition among the re-trapped individuals when comparing them to the marked toads at the time they were first captured. The important advantage of PIT tagging is the fact that all individuals are marked in the same way and their handling is similar. This makes it possible to compare various demographic parameters (growth rate, survival etc.). In addition, the number of animals that can be permanently marked using PITs is several times higher than through the use of codes resulting from the clipping of fingers and toes.

The main aim of this article is to present an uncomplicated method of estimating return rate on a portfolio of securities with Present Values presented as triangular fuzzy numbers. Determined return rates on the securities are not triangular fuzzy numbers. Despite this, we achieved a solution that is based on the arithmetic of triangular fuzzy numbers. The whole considerations are illustrated by a numerical example.

Głównym celem artykułu jest przedstawienie nieskomplikowanej metody szacowania stopy zwrotu z portfela instrumentów finansowych o wartościach bieżących przedstawionych jako trójkątne liczby rozmyte. Wyznaczone stopy zwrotu z poszczególnych składników nie są trójkątnymi liczbami rozmytymi. Pomimo tego uzyskano takie rozwiązanie, które bazuje na arytmetyce trójkątnych liczb rozmytych. Całość rozważań zilustrowano przykładem numerycznym.

The contribution is aimed on the analysis of company’s profitability especially on rate of return on assets – ROA indicator. The article is divided into two parts. In the first part is characterized indicator ROA and the ROA is disaggregating into two components: profit margin and total assets turnover. In the next part are analyzed the main factors that impact ROA and determine the level of the ROA. The main factors can be classified as operating leverage, cyclicality of sales and product life cycle.

The basic task of the experimental studies related in the article was to learn about the specificity of the Polish population as far as response of potential respondents is concerned to marketing research conducted with the use of the method of postal survey. To this end significance of effect of 15 variables on the return rate of the questionnaires was checked. The variables were distinguished on the basis of analysis of the relevant literature as well as of study results and Polish university teachers' experiences. A900 person random sample was drawn with the help of acomputer algorithm that was representative of the whole of adult Lublin residents with respect to age and sex. The whole drawn sample was divided into 16 experimental groups, each group numbering 50 subjects, and one control numbering 100 subjects. Each of the distinguished groups represented a different variable that was studied. The study results show that enclosing an envelope for the reply, reminding of the reply, enclosing a greater sum of money with the questionnaire, and a higher education and older age of the possible respondents had a positive effect on the percentage of returned questionnaires. The percentage was decreased when the envelopes containing the questionnaires were franked, the volume of the questionnaires was bigger, the survey was under the auspices of a private study centre, the subject was prenotified about his participation in the survey and when too small a sum of money was offered for the participation (50 gr). However, such variables as the subject of the survey, anonymity of the respondents, a repeated dispatch of the questionnaires, lottery and the sex of the respondents did not have a significant effect on the degree of return in the light of the obtained results. If anonymity was not guaranteed, or respondents were offered taking part in the study in return for filling in the questionnaire, and in the case of female respondents we can only talk about tendencies to decrease the return rate.
