Tytuł:: Party Switching as a Media Phenomenon in the Election Campaign
Autorzy:: Kołodziej, Szymon

Opis:: The article presents changes that take place in mass media during and after the party switching. The main reason why politicians are changing „their colors” - is that they want to become the celebrities. This work is an attempt of research about possible motivation of those figures. It is also important to consider if exist characteristic features that are assigned to identified political types?

Opis:: The analysis of the vehicle acceleration process is a current topic based on the aspects related to the general characteristics of the car, its parameters, design, drive unit performance, and the influence of external factors. However, the ability to accelerate is essential from the point of view of the active safety of the car. Often the dynamic parameters are determined on the basis of the car acceleration test carried out on a level road with good surface in terms of the acceleration time is not reliable and the credibility of such results depends on many factors. Therefore in the article, the authors assessed the dynamic and energy parameters of the car motion, in which the intensity of acceleration of the car with different intensities was examined. The acceleration intensity test was carried out from the set initial speed of the car of 45 km/h to the final speed of 120 km/h at a constant gear ratio, and the set intensity of the acceleration process resulted from the constant throttle with a constant deflection of the accelerator pedal. Acceleration was carried out in two variants, the first for a normal internal combustion engine and the second for the same engine but additionally equipped with a short-term boost system. In this way, it influences the increase in power and energy in the car drive system, changing its acceleration intensity. Variable car acceleration intensity was obtained in the range from 0.12 to 1.37 m/s2, and energy consumption at the level of 0.4 to 1.2 MJ in the distance of 1/4 mile. The article proposes a combination of energy parameters and engine power in order to assess the acceleration dynamics, for this purpose, the specific energy consumption of the car was determined, ranging from 0.35 to 2.0 J/(kg∙m), which was related to the engine power, denoting it with the dynamics index. The study focuses on the assessment of the relationship between the specific energy consumption and acceleration of passenger cars in the available powertrain system using a new dynamics index. The proposed dynamics index combines the energy and dynamic parameters of the car to be able to objectively quantify the acceleration process.
