    One of the key elements related to calculating Customer Lifetime Value is to estimate the duration of a client’s relationship with a bank in the future. This can be done using survival analysis. The aim of the article is to examine which of the known distributions used in survival analysis (Weibull, Exponential, Gamma, Log‑normal) best describes the churn phenomenon of a bank’s clients. If the aim is to estimate the distribution according to which certain units (bank customers) survive and the factors that cause this are not so important, then parametric models can be used. Estimation of survival function parameters is faster than estimating a full Cox model with a properly selected set of explanatory variables. The authors used censored data from a retail bank for the study. The article also draws attention to the most common problems related to preparing data for survival analysis.Jednym z kluczowych elementów związanych z wyliczaniem wartości klienta w czasie (Customer Life Time Value) jest oszacowanie długości trwania relacji klienta z bankiem w przyszłości. Można ją oszacować z wykorzystaniem metod analizy przeżycia. Celem artykułu jest sprawdzenie, który ze znanych rozkładów wykorzystywanych w analizie przeżycia (Weibulla, wykładniczy, gamma, logarytmicznie normalny) najlepiej opisuje zjawisko odejść klientów z banku. Jeśli celem jest oszacowanie rozkładu, według którego „przeżywają” określone jednostki (klienci banku), a czynniki, które to powodują, nie są aż tak istotne, to modele parametryczne mogą być wykorzystane. Oszacowanie parametrów funkcji przeżycia jest szybsze niż oszacowanie pełnego modelu Coxa z odpowiednio dobranym zestawem zmiennych objaśniających. Do badania wykorzystano dane cenzurowane banku detalicznego. W artykule zwrócono uwagę na najczęstsze problemy związane z przygotowaniem danych do analizy przeżycia

    Planning in Brazil, India and Germany

    Planning is a fundamental cognitive ability that helps in organizing and structuring events unfolding in a person\u27s daily life. Two studies are presented that analyze planning behavior in different cultures: Brazil, India, and Germany. The first is a cross-cultural psychological study in which students develop plans for uncertain problem scenarios. The second study follows a cultural psychological tradition. Workers from different domains are interviewed about their life problems and plans. The strengths and the weaknesses of both approaches become obvious in the description and discussion of these two studies. The cross-cultural study sheds light on cross-cultural similarities and differences in planning in Brazil, India, and Germany. The cultural psychological approach yields data regarding a theoretical model on the specific cultural influences on planning

    Decision Making in Individualistic and Collectivistic Cultures

    How do cultural values influence individuals\u27 decision making? One would expect answers to this question either from cognitive psychology or from cross-cultural psychology. Cognitive theories on decision making, however, rarely consider the factor of culture, and research in cross-cultural psychology deals only to a small extent with decision making. Therefore the study of culture and decision making is a relatively new and unexplored field. In this paper normative and descriptive approaches to decision making are discussed and three cross-cultural studies on decision making in individualistic and collectivist cultures using different methodologies are described. The results are integrated into a model that can be helpful to derive specific hypotheses for further studies in this field

    In the 17th century, the hagiography and iconography of Bishop Iohannes Traguriensis were enriched by various members of Trogir’ s noble families. In this promotion of the cult of the local beato, Dominik Andreis stands out with his efforts: he was the author of an unpublished Litany in Croatian (1632), the instigator of publishing an Italian Vita by Giovanni Francesco Loredan (1648), and the sponsor of a three act drama by Girolamo Brusoni (1656), performed in Trogir with musical intermezzos and published two years later (1658)
