Opis:
The subject of this work is the use of social network analysis to increase the effectiveness of methods used to predict churn of telephony network subscribers. The social network is created on the basis of operational data (CDR records). The result of the analysis is customer segmentation and additional predictor variables. Proposed hybrid predictor employs set of regression models tuned to specific customer segments. The verification was performed on data obtained from one of the Polish operators.

Opis:
Companies which decide on socially responsible activities usually take into consideration benefits including the marketing effects of CSR programmes. However, in order to achieve that, the information about the socially responsible activities of companies must be spread and reach the audience of the company. That includes stakeholders related to the company that might be interested in receiving information about the social initiatives undertaken by the company. These stakeholders are connected with the firm through the network of social ties (SN). The main goal of this article is to present a theoretical framework of roles that these networks of social ties play in the effective communication of CSR activities. This paper is divided into three parts. The first one concerns the problem of how to communicate the involvement of a company in social initiatives. The second one contains the description of possible communication processes and strategies. The last one presents the analysis of the social networks perspective and its main characteristics and, in conclusion, it summarizes the main benefits a company can gain by applying the SN concept to CSR communication in the area of attribution and information spread through various channels.

Opis:
Traditionally aging research focused on the disintegration of social ties, however it has recently been observed that whom we contact has a larger impact on well-being (Cacioppo et al., 2009). The authors used data from the Social Networks II module of the International Social Survey Programme to investigate the role of social network components in successful aging. A factor analysis on 1221 Polish participants revealed 4 factors that were interpreted as: close, medium, and distant family, and friends. Well-being variables were most strongly related to contact with distant family, while SS variables were most strongly related to friends. Given SS was strongly related to distant family, while perceived SS was strongly related to close family. All family contacts decreased with age, though only distant family contacts were proactively managed. These results indicate the importance of distant family in Poland, in contrast to other countries.

Opis:
In this article, we present an idea of combining social networking websites and modern mobile devices abilities to transfer social networking activity to a higher level. Nowadays, these devices and websites are used to offer ability of remote communication (phone calls, message exchange etc.), which potentially can be used to notify people about meetings in the real world. Since the current social network models do not provide enough information for such notification (social networking websites are examples of social networks) a new social network model that will be suitable for the above mentioned application is proposed and a new social platform that base on mobile devices is introduced. This platform can notify users when their friends are nearby. The paper presents the model and the simulation that verifies the approach.

Opis:
In a short period of time, Ukrainians became the second largest foreign community living in Portugal. Without historical ties linking the two countries, the ‘migration industry’ as well as positive feedback and assistance provided through pioneers’ social networks were decisive for the constitution and rapid expansion of the flow. However it slowed down in only few years and the economic crisis affecting Portugal since 2008 has introduced new limits to a possible future expansion. The goal of the paper is to provide insights with respect to the evolution of the flow, particularly looking at mechanisms of assistance and feedback provided and received within social networks, including the role of the ‘migration industry’. We explored quantitative and qualitative data collected through questionnaires applied to 306 Ukrainians and interviews conducted with 31 Ukrainians in the Lisbon Metropolitan Area in 2011 and 2012. The research confirms the importance of assistance received through social networks at different stages of the preparation of the move, upon arrival and throughout the settlement process in Portugal. We conclude that negative opinions on the present economic opportunities in Portugal have replaced initial positive perceptions about labour market opportunities and this information is being transmitted through social networks to Ukrainians back in Ukraine. We suggest that the significant decrease of the inflow can probably be explained by negative feedback and a more limited willingness to assist the migration of others. Future trends in the migratory flow of Ukrainian citizens to Portugal as well as the permanence of these immigrants in the country are uncertain. On the one hand, migrants are struggling to live through the crisis, while the recent social upheaval in Ukraine pushes them to leave.

Opis:
Recent technological innovations (Web 2.0) in today’s society mean that a major socio-anthropological change is occurring. On the net, audiences can experience new forms of participation, share information and entertainment practices, and establish new relationships. This paper describes the main characteristics of Web 2.0 with specific reference to the Italian context and categories of users who use social networks (and their motivations), using the latest national survey data. This paper analyzes changes in the identity and culture of consumption,which thanks to social media are today expressed according to the logic of experience and performance. Through social media, performative consumption represents one of the most suitable way to describe the multiple aspects of the contemporary consumer’s identity.

Opis:
The purpose of this study is to determine the relationship between the adoption of the social networks by teaching candidates and their loneliness. With this purpose in mind, 133 students from education faculties were involved in this study. In the study, the UCLA Loneliness Scale and the Social Networks Adoption Scale were applied to the students. After using the SPSS 18.0 program, the results from the scales were deduced using the Pearson Correlation, Independent t-Test, and One-Way Analysis of Variance (ANOVA). A significant relationship between students’ scores of loneliness and the usage of online social networks was revealed. The conclusion is that the loneliness scores of the students increase according to the frequency students use social networks. In addition, it can be said that the loneliness situation of students and their adoption of social networks does not change according to the universities in which they study.

Opis:
In this paper, I focused particular attention on the relationship between the structure and dynamics of complex networks. I am convinced of importance of measuring the structural properties of evolving networks in order to characterize how the connectivity of the investigating structures changes in time. Network measurement are therefore essential in my investigation. I intend to test how the non-stability of structure properties can be viewed as a factor that show abnormal state of the system (e.g. increasing of terrorism activity) modeled by complex networks. Complex networks are commonly modeled by means of simply or directed graphs. In some cases the use of graph to represent complex networks does not provide a complete description of the real-world systems under investigation. Consequently, I will formally introduce the hypernetwork concept as generalization for representing complex networks and will call them complex hyper-networks.

Opis:
Previous research in social science established the existence of mutual relationship between cultural tastes and social networks. What is less known, however, is how this connectivity translates into tangible social benefits (social capital). By applying the resource generator tool, the article explores the extent to which access to different social resources (social capital) is related to pursuing different cultural activities, independent of social standing and network features. Empirically, the possibilities of locally representative survey data (N = 1010) from Poland (2017) are exploited. The analysis brings two main findings: (i) participation in elite culture is positively associated with better access to instrumental resources (lending money, job assistance), (ii) while popular culture is more relevant to “information and (cultural) influences” social capital and to general access to resources. The contribution of the study is to show that cultural consumption may assist in the accumulation of important social resources and thus contribute to solidifying social inequalities

Opis:
Conventional economic theories assume that competing firms act independently. This theoretical assumption is applied to economic policies and anti-trust legislation. In contrast, economic sociology describes competition as a special type of social action that is oriented towards others. More specifically, to remain in the market, competing firms monitor one another and cooperate by establishing inter-organisational social ties. This paper demonstrates that increasing market pressures, including higher levels of competition and stronger bargaining power among exchange partners, does not disrupt social ties but promotes them. Data for the analysis were collected in 2007 from 501 managers of retail chains and their suppliers in five Russia’s cities (Moscow, Saint Petersburg, Yekaterinburg, Novosibirsk, and Tyumen). The sample includes firms of different sizes that operate in the food and electronics sectors of the consumer market.

There are many tools, languages and methods for developing large-size software systems and architectures represented by social network systems. However, no research has been done yet to uncover the reasons behind the selection and usage of such systems in terms of choosing the right architecture and data storage. We describe effective approach to developing specific parts of social Network systems with special attention to data layer (using Hadoop, HBase and Apache Cassandra), which forms the foundation of Any social network system and is highly demanding for performance and scalability.

Opis:
In this paper a new method for information hiding in open social networks is introduced. The method, called StegHash, is based on the use of hashtags in various open social networks to connect multimedia files (like images, movies, songs) with embedded hidden messages. The evaluation of the system was performed on two social media services (Twitter and Instagram) with a simple environment as a proof of concept. The experiments proved that the initial idea was correct, thus the proposed system could create a completely new area of threats in social networks.

Our aim is to model the dynamics of social networks, which comprises the problem of how people get to know each other, like each other, detest each other, etc. Most existing models are stochastic in nature and, obviously, based on random events. Our approach is deterministic and based on ordinary differential equations. This should not be seen as a challenge to stochastic models, but rather as a complement.

Opis:
Tendencies of mediatization, globalization, commercialization etc. in modern societies cause a loss of relevance of traditional agencies of socialization. Individuals are increasingly challenged to enfold their socialization on their own. Media products become highly relevant for an individual’s socialization. To be able to manage the demands of socialization, the individual needs to develop sophisticated competences of communication. The competences of communication enable the individual to identify and reflect his/her personal needs. Identity is conceived as the realization of an individual’s competence of construction of communication in interactive situations. Online social networks such as Facebook.com provide spaces of communication, in which individuals can work on their identity in processes of interaction. By methods of network analysis this research explores the impact of structures of social networks on the individual’s competences of communication and, hence, the impact on identity constructed on social networks.

Aim. This article presents the results of research whose aim is to establish if social networks are useful tools to promote social relationships and support for the elderly citizens. Method. One hundred thirty people over the age of 65 participated in the research. For this purpose, the scale “elderly people and social network” (elaborated ad hoc) was applied. Results and conclusion. The results obtained through descriptive analysis of the gathered data indicate that social networks provide support for elderly people who had already acquired digital competence in the past. The study also reveals that there are personal variables, especially of an educational nature, that determine the acquisition of an active role as generators and producers of digital content (prosumers). In conclusion, it could be said that social networks have a positive influence on the well-being of the elderly and their fight against undesirable loneliness. The more heterogeneous the social network is, the more active the elderly people are.
