Opis:
Celem badań była analiza atrakcyjności oferty dostępu do mobilnego Internetu wśród klientów. W pracy wykorzystano podejście gradacyjne do wizualnej prezentacji danych oraz dokonania oceny podobieństwa pakietów pod względem ceny w różnych grupach wiekowych klientów. Pozwoliło to sformułować wnioski, że atrakcyjność oferty dostępu do mobilnego Internetu różni się w zależności od grupy wiekowej klientów oraz kategorii dochodowej. Jednocześnie badanie pozwoliło zidentyfikować segmenty nabywców o podobnych cechach.
The aim of the study was to analyze the attractiveness of the mobile internet offer. In this work the grade analysis approach was used to visualize the data and to assess the similarity of internet packages in terms of price and customers age groups. This allowed formulating conclusions that the attractiveness of mobile internet packages varies depending on the customers’ age and income category. At the same time research has identified segments of customers with similar characteristics.

Opis:
The paper attempts to compare European Union countries in terms of the dynamics of changes in the value of lamb meat imports in the period 2003-2017. The standard against which this comparison was made was the average value, which should be understood as the growth dynamics of the examined feature for all EU countries together. For this purpose, tools related to the so-called Grade Data Analysis, such as the index of the unlikeness of structures “ar” (in this case a good tool to determine the direction of changes and the speed of these changes for all EU countries) and overrepresentation maps (used to visualise these changes and for their interpretation). Additionally, with the help of GDA methods, EU countries were divided into groups characterised by smaller, medium and higher dynamics of changes in lamb imports. It can be concluded that the most dynamic growth in imports of this type of meat is found among the newest EU member states. This may indicate a change in dietary preferences in these countries. It may also be related to greater accessibility to goods previously considered as luxury, greater awareness of so-called healthy foods and the improved standard of living of societies that have joined the European Union.

Tematy:

Opis:
The discussion about justification for the very existence of Senate, as it was the case in previous years, also took place prior to the 2015 parliamentary elections. Postulates for the second chamber of parliament to be abolished are the inseparable element of election campaigns in Poland. Announcements of total abolishment or change of: form, competencies or number and the election principles for members of Senate, although they found their expression in the 2015 election programs of some of the political parties, but they were never applied after elections. The single member Senate constituencies secured seats almost exclusively for candidates supported by one of the two strongest political parties, that is the Law and Justice (PiS) and the Civic Platform (PO). Even if in the result of 25 October 2015 elections four independent candidates were elected for senators, three of them used support of political parties, using a rule well proven four years earlier: there is not senator without a political party protector. The 40% support for PiS which turned into 61% of seats indicates that the election system for Senate leads to overrepresentation of election winners.

Opis:
The research of food preferences has, besides a sociological aspect, an economic aspect and is a good starting point for estimating the willingness to incur expenditures on the consumption of individual products. In the paper, the authors compared food preferences on the Asian market for 9 product groups. Due to the complexity of the problem, the study included 17 selected countries of Central and Southeast Asia (China, Mongolia, Japan, India, Thailand, Indonesia, Kazakhstan, Uzbekistan, Tajikistan, Malaysia, Myanmar, the Philippines, Pakistan, Cambodia, Vietnam, Laos, Sri Lanka). The research was carried out on data from 2001 to 2013 with the use of the methods of gradual data analysis. In some countries there were no major changes in nutrition and food consumption, which can be explained by the stabilized political and socio-economic situation. The best example is Thailand.
