    Opis:
    This paper discusses the impact of delayed information on the social models of replicator dynamic. Internal fixed point is here the optimal decision in the population. Examples and simulations confirm presented results. Here is described both the standard replicator dynamic and the modified model, which assumes that players imitate opponents taking strategies with a higher average payoff in the past. Moreover the model, in which each strategy has its own delay is presented

    the History of Education at the University of Szczecin
    Opis:
    The History of Education, one of the courses offered at teacher education studies at the University of Szczecin, has been taught since the 1960’s. It was then when Teacher Education College in Szczecin was set up as a branch of Adam Mickiewicz University, Poznań. In 1973 Teacher Education College was transformed into an independent unit – Pedagogy Academy. The establishment of the University of Szczecin in 1985 marked a new chapter in the process of the development of the history of education as a course offered at pedagogical studies. History of Education Department was set up in 1992 and professor Danuta Koźmian was chair of the department throughout its existence. Scientific and didactic work of professor Danuta Koźmian first at Teacher Education College, through Pedagogy Academy and the University of Szczecin has been crucial for the development of the history of education as a course taught at teacher education studies in Szczecin. In 2008 professor Danuta Koźmian retired and the Council of the Faculty of Humanities at the University of Szczecin established the Chair for the History of Education appointing professor Wiesław Andrukowicz,  Ph.D its head.

    Opis:
    This paper presents the basic properties of the extended Gini coefficient as a risk measure. We define the measure of systematic risk (beta coefficient) and the correlation between securities based on the extended Gini coefficient. The presented issues we illustrate with empirical research conducted on the basis of selected shares quoted on the Warsaw Stock Exchange.

    Opis:
    Architectural structures’ nodal coordinates are significant to shape appearance; vertical overloading causes displacement of the joints resulting in shape distortion. This research aims to reshape the distorted shape of a double-layer spherical numerical model under vertical loadings; meanwhile, the stress in members is kept within the elastic range. Furthermore, an algorithm is designed using the fmincon function to implement as few possible actuators as possible to alter the length of the most active bars. Fmincon function relies on four optimization algorithms: trust-region reflective, active set, Sequential quadratic progra mming (SQP), and interior-point. The fmincon function is subjected to the adjustment technique to search for the minimum number of actuators and optimum actuation. The algorithm excludes inactive actuators in several iterations. In this research, the 21st iteration gave optimum results, using 802 actuators and a total actuation of 1493 mm.MATLAB analyzes the structure before and after adjustment and finds the optimum actuator set. In addition, the optimal actuation found in MATLAB is applied to the modeled structure in MATLAB and SAP2000 to verify MATLAB results.

    Water level fluctuations in the Turawa Reservoir in relation to the tourist use of the water body

    Opis:
    The aim of the paper is to assess the fluctuations of water levels in the Turawa Reservoir (50° 43' N, 18° 08' E) in relation to the tourist use of the water body. The reservoir is situated within the macroregion of the Silesian Lowland in the mesoregion of the Opole Plain. In administrative terms, the reservoir is situated in the pole Province within the borough of Turawa. In hydrological terms, in turn, it is situated in the catchment area of the Mała Panew river, which belongs to the basin of the Odra river. The Turawa Reservoir was opened for use in 1938, and in 1948 it was filled with water to its maximum for the first time. At present, the surface area of the reservoir, when it is filled with water to its maximum, is about 20.8 km2, its volume 99.5 mln m3, and its depth exceeds 13 meters. In the period of hydrological years 1976-2000 water levels in this reservoir were characterized by high, unnoticed in natural conditions, amplitudes of changes reaching 6.99 m. Anthropogenically stimulated fluctuations in the water level result in conflicts in terms of tasks and functions that the Turawa Reservoir was designed for. Changes in the level of the water surface in the Turawa Reservoir resulted from the impact of the natural factors (thaw and rainfall related high water levels), as well as anthropogenic ones (the need to improve sailing conditions, water supply for industrial and municipal needs). Decreasing the fluctuations of water levels in the Turawa Reservoir is necessary in order to maintain its tourist-recreational functions and keep the ecological condition of its waters at the appropriate level.

    Cationic linear poly-cis-isoprenoid prepared from natural plant polyprenol in a mixture with dioleyl phosphatidylethanolamine was found to be an effective lipofection agent for eukaryotic cells. The transfecting activity is related to the poly-cis structure of the polyprenyl chain.
