Emotional agents at the square lattice

We introduce and investigate by numerical simulations a number of models of emotional agents at the square lattice. Our models describe the most general features of emotions such as the spontaneous emotional arousal, emotional relaxation, and transfers of emotions between different agents. Group emotions in the considered models are periodically fluctuating between two opposite valency levels and as result the mean value of such group emotions is zero. The oscillations amplitude depends strongly on probability ps of the individual spontaneous arousal. For small values of relaxation times tau we observed a stochastic resonance, i.e. the signal to noise ratio SNR is maximal for a non-zero ps parameter. The amplitude increases with the probability p of local affective interactions while the mean oscillations period increases with the relaxation time tau and is only weakly dependent on other system parameters. Presence of emotional antenna can enhance positive or negative emotions and for the optimal transition probability the antenna can change agents emotions at longer distances. The stochastic resonance was also observed for the influence of emotions on task execution efficiency.Comment: 28 pages, 19 figures, 3 table

Coevolution of Information Processing and Topology in Hierarchical Adaptive Random Boolean Networks

Random Boolean networks (RBNs) are frequently employed for modelling complex systems driven by information processing, e.g. for gene regulatory networks (GRNs). Here we propose a hierarchical adaptive RBN (HARBN) as a system consisting of distinct adaptive RBNs - subnetworks - connected by a set of permanent interlinks. Information measures and internal subnetworks topology of HARBN coevolve and reach steady-states that are specific for a given network structure. We investigate mean node information, mean edge information as well as a mean node degree as functions of model parameters and demonstrate HARBN's ability to describe complex hierarchical systems.Comment: 9 pages, 6 figure

CYBEREMOTIONS – Collective Emotions in Cyberspace

AbstractEmotions are an important part of most societal dynamics. As with face to face meetings, Internet exchanges may not only include factual information but may also elicit emotional responses; how participants feel about the subject discussed or other group members. The development of automatic sentiment analysis has made large scale emotion detection and analysis possible using text messages collected from the web. We present results of two years of studies performed in the EU Large Scale Integrating Project CYBEREMOTIONS (Collective emotions in cyberspace) Our goal is to understand the role of collective emotions in creating, forming and breaking-up ICT mediated communities and to prepare the background for the next generation of emotionally-intelligent ICT services. Project results have already attracted a lot of attention from various mass media and research journals including the Science and New Scientist magazines. Nine Project teams are organised in three layers (data, theory and ICT output)

Determination of Aldehydes in Wet Deposition

The paper presents two sample preparation procedures for the determination of aldehydes in wet deposition. In both cases the 2,4-dinitrophenylhydrazine derivatization and solid phase extraction were applied. The derivatization in method A was applied before the extraction, the extraction in method B was carried out with simultaneous derivatisation. Accuracy of both methods was evaluated on the basis of the analysis of aqueous solutions of selected carbonyl compounds. Both methods were characterized by good recovery, however, due to the precision of the method expressed as RSD for testing of environmental samples the method B was used

Social responsibility activities of higher education institutions – good practices

Wdrażanie gospodarki opartej na wiedzy wpływa na zmiany w szkolnictwie wyższym. Istotnym elementem koncepcji jest wprowadzenie efektywnych mechanizmów zarządzania wiedzą, które prowadzą do konkurencyjności i innowacyjności uczelni na arenie polskiej oraz międzynarodowej. Dlatego też w obszarze działań strategicznych uczelni niezbędne jest prezentowanie nie tylko osiągnięć naukowych, ale i czynników społecznych, ekologicznych, ekonomicznych wspierających postrzeganie uczelni jako organizacji służącej otoczeniu. Relacje uczelni ze środowiskiem lokalnym mają niebagatelne znaczenie dla rozwoju regionu i podkreślają odpowiedzialność instytucji edukacyjnych w tym zakresie. Odpowiedzialność społeczna uczelni prezentowana jest w postaci raportów społecznych, zgodnie z koncepcją społecznej odpowiedzialności. Istnieje wiele dobrych praktyk opracowanych przez uczelnie zagraniczne, które interpretują społeczną odpowiedzialność uczelni w zróżnicowany sposób, w zależności od planów rozwojowych. Jednakże dotąd żadna polska uczelnia techniczna nie opracowała raportu społecznej odpowiedzialności. Celem artykułu jest zaprezentowanie wybranych działań zagranicznych uczelni podejmowanych w ramach społecznej odpowiedzialności oraz przedstawienie ścieżki raportowania społecznego w uczelni technicznej na przykładzie Akademii Górniczo-Hutniczej im. Stanisława Staszica w Krakowie (AGH), na podstawie analizy dokumentów. Autorzy dokonali przeglądu raportów społecznych uczelni zagranicznych publikowanych na stronach internetowych uczelni oraz Sprawozdania Rektora AGH z 2016 r. [Sprawozdanie, 2017]. Z analizy zaprezentowanej w artykule wynika, iż AGH wypracowała szereg dobrych praktyk z zakresu społecznej odpowiedzialności uczelni, które nie zostały dotychczas zaprezentowane w formie raportu społecznego.An implementation of the knowledge economy influence on changes in higher education. A significant element of the concept is introducing an effective knowledge management mechanism, which lead to greater competitiveness and innovation of the university in both a Polish and international context. Therefore in the university’s strategic areas of action it is necessary to present not only scientific achievements but also social, ecological and economic factors in the form of social reports, in accordance with the concept of social responsibility and new role of universities as the organizations serving its environment. There are many examples of good practices developed by foreign universities, which interpret the university social responsibility in a different way, depending on their development strategies. So far social responsibility report has not been published by any Polish technical university. The aim of the article is to review the university social responsibility practices in the foreign universities as well as to present the stages of social responsibility reporting in the technical university on the example of AGH University of Science and Technology. The article states that AGH has developed significant number of good practices in social responsibility, which have not yet been presented in the form of social report

A Web-GIS tool for diagnosing spatial orientation of young adults: design and evaluation of Geo-Survey

Abstract Spatial orientation is the effectiveness with which one is able to assess the mutual location of objects relative to a point of reference or a system of coordinates. Traditionally, this ability has been evaluated through field navigation tests, which do not take into account the prevailing influence of free online maps and virtual walks on a person’s interpretation of space. In this context, this study presents a Web-GIS tool designed and developed to examine spatial orientation skills in the context of the used map type. The tool, named Geo-Survey, enables combination of survey questions with customized maps, providing users with a set of possible answer types. Moreover, using the unique concept of predefined answers, the tool attempts to automate the process of analysing research results. The tools’ performance is evaluated via assessing the spatial orientation skills of a group of young adults
