Opis:
The paper aimed at identifying the effects of the coincidence of socio-economic status and the advancement of the family life cycle on the savings rate. The multilevel regression model for data from empirical surveys was used. The obtained results allow us to explain how the differentiation of the saving rate that causes a poor fit of LCH models to the observed reality occurs. Ascribed to this differentiation is the explanation that allows us to reduce the area of unpredictability of the savings rate. These results show that the social representations of saving characteristic for various socio-economic groups are crucial factors that explain the variability of the savings rate, moderating its sensitivity to the demographic factors as defined in the economic theory. Moderation leads to two different tendencies. The first occurs among the households of a relatively low status and lies in the extension of consumption along with age, and it is stronger the lower the status of the household head is. The second, completely reverse, is present among households of a relatively high social status. The contraction of the time horizon of consumption manifests among these households, and it is stronger the higher the socio-economic status of a household head is.

Opis:
The paper describes the problem of crude oil transfer in a port oil terminal and includes the safety analysis of this operation and analysis of potential causes and possible scenarios of oil spill events in a port terminal. The operation process of crude oil transfer is described and its statistical identification is given. The reliability and availability analysis of the system of crude oil transfer in a port terminal is performed. Moreover, analysis of crude oil transfer process taking into account the human factor is provided. The Fault Tree Analysis and sensitivity analysis for oil spill event in a port terminal is proposed to identify and analyse potential causes and possible scenarios of oil spill. Introducing methods for the prevention of oil spills, special attention is paid to safety procedures during liquid cargo transfer. Technical solutions used in oil terminals are described and recommendation regarding the Emergency Shutdown System are given. Additionally, associated safety systems, such as surge relief system, are described. Emphasizing the role of human factor in the process of crude oil transfer and its safety, trainings on the Liquid Cargo Handling Simulator are proposed to improve skills and knowledge of personnel on board and ashore.
