Niełatwa archeologia klifów – przypadek stanowisk w Bagiczu

The following paper presents the problem of archaeological sites located on cliffs on the Southern Baltic Sea shore. This article discusses issues related to a necessity of solving the problem of this kind of research, related to methodological, as well as documentation and preservation standards based on preliminary results of the project conducted in Bagicz area (Ustronie Morskie commune). In this region four new structures were noted on a cliff surface. The key to understand the situation of archaeological sites located on a cliff areas is the knowledge of the processes related to their formation and activity. All of them have a huge impact for the state of preservation of the cliff, however they have various intensity level depending on the part of the Baltic Coast.The following paper presents the problem of archaeological sites located on cliffs on the Southern Baltic Sea shore.

Czy jesteśmy „społeczeństwem honoru”? Rekonstrukcja pojęcia honoru w wybranych orzeczeniach polskich sądów

The existence of honour as a particular value is not unique, restricted to the boundaries of certain states, nationalities or ethnicities only. Yet, a distinction can be found in the literature between so-called ‘societies of honour’ and ‘modernised societies’. It is believed that in ‘societies of honour’ honour plays a central role in regulating social relations, and in ‘modernised societies’ based on the rule of law its importance is marginalised. This article is a contribution to the discussion on the adequacy of the discussed division based on the example of Polish society. Due to the fact that an important feature of this distinction is the juxtaposition of law and honour as tools for regulating social relations, the starting point of the analysis of this issue is to answer the question whether the concept of ‘honour’ exists in Polish law, and if so, how it is defined and in what contexts it appears. Due to the complexity of this issue, the subject of the article was limited to a specific problem – the analysis of selected judgments of Polish courts and the reasons underlying these judgments. The research allowed to identify the provisions of Polish law which refer (or could refer) to honour. Based on the analysis made, it may be stated that both, judges as well as parties to court proceedings, consider honour as a protected, legally accepted value.Występowanie honoru jako pewnej szczególnej wartości nie jest czymś wyjątkowym, ograniczonym do granic określonych państw, narodowości czy etniczności. Mimo to w literaturze można odnaleźć rozróżnienie między tzw. społeczeństwami honoru i społeczeństwami zmodernizowanymi. Uważa się, że w „społeczeństwach honoru” honor pełni rolę głównego narzędzia regulacji stosunków społecznych, a w „społeczeństwach zmodernizowanych”, opartych na prawie, jego znaczenie jest zmarginalizowane. Niniejszy artykuł stanowi przyczynek do dyskusji nad adekwatnością omówionego podziału na przykładzie polskiego społeczeństwa. Z racji tego, że istotną cechą wskazanego rozróżnienia jest przeciwstawianie prawa i honoru jako narzędzi regulacji stosunków społecznych, punktem wyjścia analizy problemu jest udzielenie odpowiedzi na pytanie, czy w polskim prawie występuje pojęcie „honoru”, a jeżeli tak, jak jest definiowane i w jakim kontekście się pojawia. Ze względu na złożoność tej problematyki, temat artykułu został ograniczony do konkretnego problemu – analizy wybranych wyroków polskich sądów wraz z uzasadnieniami. Przeprowadzone badania pozwoliły na wskazanie przepisów polskiego prawa, które odnoszą się (albo mogą się odnosić) do honoru, a także na stwierdzenie, że zarówno przez sędziów, jak i przez strony postępowań sądowych honor jest uznawany za chronioną prawnie, powszechnie akceptowaną wartość

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

Negative emotions boost users activity at BBC Forum

We present an empirical study of user activity in online BBC discussion forums, measured by the number of posts written by individual debaters and the average sentiment of these posts. Nearly 2.5 million posts from over 18 thousand users were investigated. Scale free distributions were observed for activity in individual discussion threads as well as for overall activity. The number of unique users in a thread normalized by the thread length decays with thread length, suggesting that thread life is sustained by mutual discussions rather than by independent comments. Automatic sentiment analysis shows that most posts contain negative emotions and the most active users in individual threads express predominantly negative sentiments. It follows that the average emotion of longer threads is more negative and that threads can be sustained by negative comments. An agent based computer simulation model has been used to reproduce several essential characteristics of the analyzed system. The model stresses the role of discussions between users, especially emotionally laden quarrels between supporters of opposite opinions, and represents many observed statistics of the forum.Comment: 29 pages, 6 figure

Spreading of diseases through comorbidity networks across life and gender

The state of health of patients is typically not characterized by a single disease alone but by multiple (comorbid) medical conditions. These comorbidities may depend strongly on age and gender. We propose a specific phenomenological comorbidity network of human diseases that is based on medical claims data of the entire population of Austria. The network is constructed from a two-layer multiplex network, where in one layer the links represent the conditional probability for a comorbidity, and in the other the links contain the respective statistical significance. We show that the network undergoes dramatic structural changes across the lifetime of patients.Disease networks for children consist of a single, strongly inter-connected cluster. During adolescence and adulthood further disease clusters emerge that are related to specific classes of diseases, such as circulatory, mental, or genitourinary disorders.For people above 65 these clusters start to merge and highly connected hubs dominate the network. These hubs are related to hypertension, chronic ischemic heart diseases, and chronic obstructive pulmonary diseases. We introduce a simple diffusion model to understand the spreading of diseases on the disease network at the population level. For the first time we are able to show that patients predominantly develop diseases which are in close network-proximity to disorders that they already suffer. The model explains more than 85 % of the variance of all disease incidents in the population. The presented methodology could be of importance for anticipating age-dependent disease-profiles for entire populations, and for validation and of prevention schemes.Comment: 14 pages,5 figure

Dynamics of the segetal flora of the eastern part of the Gniezno Lake District

Wydano przy pomocy finansowej Uniwersytetu Łódzkiego oraz Komitetu Badań NaukowychThe present report describes changes in the species composition of the segetal flora during 143 years of geobotanical research. The analysis is based on historical sources of information and the author presents floristic releves were taken in the field. In the area 2114 km² of segetal habitats, 1795 floristic releves were taken, which enabled creating a collection of 37 391 floristic data possible. The work concerns a region that has been intensively colonized since the remotest time because it is the cradle of our statehood. At present it is an area of increased farm production. An attempt to define the synanthropodynamic state of the segetal flora in this area was made. Special attention was paid to directly endangered weeds (E) and potentially endangered weeds (PE).Zadanie pt.
