Opis:
The paper focuses special attention on a project named CARE. The developers of the project is NosoiFighters team, which consists of students of the Cybernetics Faculty in Military University of Technology. The system is a very creative software solution that takes advantage of pioneering sociological theories, graph/networks theory and the last but not least most advanced technologies. It has a very practical purpose, in particular nowadays: countering infectious diseases, for instance HIV/AIDS, malaria, SARS, etc. The paper demonstrates how the system can help us to nail epidemics. CARE has enormous practical potential in regions such as Africa, where there are not enough medicines to treat all who are at risk.

Opis:
Individualism-collectivism has emerged as one of the most important constructs to depict cultural differences and similarities. It is typical to examine individualism and collectivism through comparison between the cultures of the West and those of the East or comparison between various religious traditions, e.g. Christianity has been seen as the source of Western individualistic understanding whilst Buddhism as the source of Eastern collectivist understanding. The research presented in this paper explored the connections between individualism-collectivism and religiosity in Polish Catholic culture. Although Poland is an orthodox Catholic environment, gradually intensified secularization processes have been observed there. In two separate studies we examined relationships between individualism-collectivism and religiosity defined in a traditional (study 1) and secularized context (study 2).

Opis:
The Catholic religion has been inextricably connected with the Polish state through numerous historical experiences. Being an important aspect of connecting society, it can be used in an instrumental way on the political agenda. Moreover, religiousness is an important determinant of electoral decisions. The aim of the research (N=238) is to check whether religiosity affects the perception of the importance of religious principles in everyday life and religion in political life. In the presented approach, religiosity was a multidimensional variable and was conceptualized using a modified five-point Religiosity Centrality Scale (Huber 2003). It was confirmed that all dimensions of religiosity are significantly related to the assessment of the importance of religious principles. The dimension that showed the strongest correlation with the created variables was the dimension of religious cult, and the dimension that correlated the least was the dimension of reading the Catholic press.

Opis:
Social network analysis (SNA) is an important and valuable tool for knowledge extraction from massive and unstructured data. Social network provides a powerful abstraction of the structure and dynamics of diverse kinds of interpersonal connection and interaction. In this paper, we address issues associated with the application of SNA to the investigation and analysis of social relationships of people. We provide a brief introduction to representation and analysis of social networks, SNA models and methods. The main objective is to investigate the application of SNA techniques to data mining in case of two social networks Facebook and Twitter. The presented simulations illustrate how social analysis can be used to determine the interpersonal connections, importance of actors in a given social network and detect communities of people. We then discuss strength and weakness of SNA techniques.

The quotient of two linear combinations of independent chi-squares will have a generalized F distribution. Exact expressions for these distributions when the chi-square are central and those in the numerator or in the denominator have even degrees of freedom were given in Fonseca et al. (2002). These expressions are now extended for non-central chi-squares. The case of random non-centrality parameters is also considered.

Generalized F tests were introduced for linear models by Michalski and Zmyślony (1996, 1999). When the observations are taken in not perfectly standardized conditions the F tests have generalized F distributions with random non-centrality parameters, see Nunes and Mexia (2006). We now study the case of nearly normal perturbations leading to Gamma distributed non-centrality parameters.

Opis:
The aftermath of including new technologies in a modern electric system in conjunction with the incessant rise in power demand could pose a risk to the optimal operation of the system. Therefore, it becomes imperative to identify the most influential and critical nodes of such a system to avert future problems in network operation. In this paper, to identify most significant nodes of the system, the authors propose two measures of centrality in accordance with the network structural properties of a power system, namely, degree centrality (DC) and eigenvector centrality (EC). These are expressed considering the admittance matrix that exists among the interconnection of load to load nodes in an electrical power network. A critical node closeness centrality (CNCC) method is also proposed to identify critical nodes of the system. This is done by modifying the conventional closeness centrality (CC) to include the influence of interconnection that exists between network load to load nodes as captured by the admittance matrix between them. A comparative analysis of the proposed techniques with other conventional methods is also carried out. The result of the simulation shows that the proposed methods could serve as alternative tools in the identification of influential and weak nodes in a power system.

Opis:
Religiosity and dyadic coping are among the factors important for the quality of marriage, satisfaction with the relationship and the sense of happiness of the spouses. Well-being, mainly in the aspect of personal development or life goals, seems to be particularly important for couples planning to conceive a child in the near or distant future. The study involved 51 married couples postponing parenthood. Their dyadic coping, psychological well-being and the centrality of religiosity were studied. The actor-partner interdependence model was used for the dyadic analyses. There were no differences in the well-being between the spouses, however, women rated in dyadic coping and religiosity higher. The centrality of the spouses’ religiosity, and especially the congruence of their religious beliefs, seems to have a significant impact on their well-being. The obtained results seem to shed new light on the importance of dyadic coping by spouses and their religiosity for the well-being of each of them.

We use asymptotic linearity to derive confidence intervals for large non-centrality parameters. These results enable us to measure relevance of effects and interactions in multifactors models when we get highly statistically significant the values of F tests statistics. We show how to use our approach by considering two sets of data as application examples.

Opis:
The construction industry is characterized by limited resources and a high level of competition. Limited resources and a competitive environment determine knowledge and information as a particularly important resource for the development of the construction industry. A communication network is one of the elements of a knowledge management system in projects and serves to organize and maintain information links between project participants. We have analysed the communication network between project participants for residential building construction using social network analysis (SNA). The purpose of this work is the calculation and analysis centrality measures for participants in the construction project delivery. Centrality measures can answer the following questions whether the node is influential or central to the network and whether the node is critical for the flow of information in the network.

Opis:
The article analyses the transformations and the internal diversity of the oldest urban structures of central Łódź, one of the biggest Polish cities. 19th-century Łódź was one of the greatest centres of the textile industry in Europe. Currently, the city faces major challenges, including a dramatic population decrease, population ageing as well as a vast revitalisation of urban structures aimed at reinforcing the new idea of the city’s inward development. The research on the layout of Łódź is based on the modern image of the city as well as four images preserved in historical plans. The subsequent, chronological models are analysed in terms of topological features with the use of space syntax methods. The conducted research made it possible to identify the internal, configurational diversity of the historic urban core of Łódź. A seemingly monotonous, orthogonal urban layout is, from a topological perspective, highly diversified. Due to the actions undertaken in Łódź and aimed at restoring urban structures in the broad sense, the study not only has a cognitive goal, but it also carries a practical context.

Opis:
The purpose of this study was to investigate the relationship between work engagement and the psychological traits of employees, such as attitudes towards work and work ethic. Additionally, the study included demographic characteristics of employees and organizational characteristics. Research was conducted using the Polish adaptations of two well known methods: Multidimensional Work Ethic Profile and Utrecht Work Enagagement Scale, as well as the Work Attitude Questionnaire (WAQ) - a new Polish method. 360 adult employees of two large Polish regions took part in the study. The analysis showed a significant influence of hedonic-autotelic attitude, as well as four dimensions of work ethic on work engagement. It seems to be an important conclusion that work engagement turned out to be far more determined by the subject’s psychological traits than demographic and organizational ones. These results, indicating the special role of the perception of work as a central value, can be used only in the area of attitudes towards work formed during adolescence (e.g., at school, in career counseling) but also in the area of motivating the employees by the organization.

Opis:
Shakespeare travels the globe more variously and unpredictably than any other dramatist. In performance his texts have shown themselves hospitable to vastly different ideological interpretations. By making these two points, I do not mean that Shakespeare pops up around the globe, sometimes in quite extraordinary guises, without rhyme or reason. Far from it. Where Shakespeare makes his appearance this is an act of deliberate choice, by a producer, a production company, an arts foundation, a school or university, a national arts authority, or even simply an ad hoc group of Shakespeare enthusiasts. His advent is always intentional, and often contextually explicit, whatever the rationale. But the sheer variety of guises in which his work appears, the disparate cultural and ideological vogues that attach to his work, the geographical spread of art pieces, performances and installations based on Shakespeare, not to mention the diverse artistic disciplines which seize on him as an inspiration, calls for explanation. No other artist in any medium exhibits comparable artistic fertility across time and space. To claim the limelight for more than 400 years without any sign of diminution is remarkable. This article seeks to understand why this ubiquity is possible. Specifically, is there a definable textual mechanism underlying his historical and international success? At the outset it should be indicated that this paper focuses on a technical diagnosis of textual prerequisites for Shakespeare’s international success. It is not about what his plays say or mean, and only incidentally about the values they exemplify. While the paper sets out to describe textual features which make possible some of his manifold theatrical enchantments, there is no intention to describe, evoke, or celebrate those enchantments.

Opis:
The results of two applications of multi-objective genetic algorithms to the analysis and optimization of electrical transmission networks are reported to show the potential of these combinational optimization schemes in the treatment of highly interconnected, complex systems. In a first case study, an analysis of the topological structure of an electrical power transmission system of literature is carried out to identify the most important groups of elements of different sizes in the network. The importance is quantified in terms of group closeness centrality. In the second case study, an optimization method is developed for identifying strategies of expansion of an electrical transmission network by addition of new lines of connection. The objective is that of improving the transmission reliability, while maintaining the investment cost limited.
