The topic of this article is network analysis, shown as an activating method used in education. Due to a growing interest in social networking sites and an increased importance of cooperation, it is necessary to improve students' skills in the field of methods provided by Social Network Analysis (SNA). The potential of social networks can be used, for example to develop contacts, share ideas and as a communication tool. The aim of this paper is to present how students can study "network effects" − the value generated by network structures. This issue will be clarified on the example of Metcalfe's law, selected measures of the SNA method and others. The exercise presented in the article is an excellent base for conducting in-depth research using the SNA method, which in turn allows to identify barriers to the flow of knowledge, discover invisible structures and relationships, analyse the collected data quantitatively and qualitatively. The article will indicate directions of using the analysis of social networks in research works at universities.
The article shows the main factors of adblocking software usage. The study was based on data obtained by a web questionnaire. The research was focused on evaluation of ad blocking (adblock) software usage factors in five categories: (1) gender, age, and education; (2) use of advertising and sources of knowledge about advertising; (3) technical and social reasons for blocking online advertisements; (4) usage of an adblock-wall; and (5) type of online advertisement. An evaluation of adblock usage factors revealed four main technical reasons for adblock usage connected with website technology and web development problemsinterruption, amount of ads, speed, and security; and one social reason for adblock usage, namely, the problem of privacy.
The aim of the study is to analyze case studies of selected organizations in terms of their achievements in the use of social media. The profiling method applied in the study facilitated evaluating the model of the selected organization. It is an efficient technique for exploring data. Graphic objects show the individual characteristics of selected organizations. Graphical visualization makes it easy to gauge the trajectory, the direction of your company's social media strategy, and helps to make a decision to change it. Further analysis of the structure of these models may facilitate the discovery of relevant relationships between the analyzed variables.
