Not every household can afford, mainly due to limited financial resources, to meet their needs in a satisfactory manner. The aim of the article is to present selected findings of empirical research (qualitative study — FGI, IDI and quantitative study — CAPI and CAWI, requested by the respondent) carried out for the needs of the project Entrepreneurial and Consumer Behaviour of Families Caring for Children and Youth with Disabilities. The article presents the financial situation of households with achild/children with disabilities, the financial obligations and purposes of consumer credits and loans, the most acute shortages in the household, the allocation of additional income and the ways of coping with difficulties.

The effect of lead time plays an important role in inventory management. It is also important to study the optimal strategies when the lead time is not precisely known to the decision-makers. This paper aimed to examine the inventory model for deteriorating items with fuzzy lead time, negative exponential demand, and partially backlogged shortages. This model is unique in its nature due to prob-abilistic deterioration along with fuzzy lead time. The fuzzy lead time was assumed to be triangular, parabolic, trapezoidal numbers. The graded mean integration representation method was used for the defuzzification purpose. Three different types of probability distributions, namely uniform, triangular and beta were used for rate of deterioration to find optimal time and associated total inventory cost. The developed model was validated numerically, and values of optimal time and total inventory cost are given in a tabular form, corresponding to different probability distributions and fuzzy lead-time. The sensitivity analysis was performed on the variation of key parameters to observe its effect on the devel-oped model.

The article presents the question of the post-war purchases made by Polish clerks in Berlin. The intention behind those purchases was to fill the gap on the Polish market, especially as far as cars are concerned. The mechanism of those purchases was described, together with the originators and participants and the offices and services that took part in the action or controlled it. The article also contains an appraisal of that action and depicts its scale.

Artykuł podejmuje zagadnienie powojennych zakupów prowadzonych przez polskich urzędników w Berlinie, których celem było ściąganie deficytowych towarów, w tym samochodów. Przedstawiony został mechanizm jaki towarzyszył „berlińskim zakupom” – zaprezentowani zostali pomysłodawcy i uczestnicy akcji oraz urzędy i służby w nim partycypujące bądź je kontrolujące. Podjęto również próbę oceny zjawiska i jego skali.
