Opis:
Background: UML class diagrams can be automatically validated if they are compliant with a domain knowledge specified in a selected OWL 2 domain ontology. The method requires translation of the diagrams into their OWL 2 representation. Aim: The aim of this paper is to present transformation and verification rules of UML class diagrams to their OWL 2 representation. Method: The analysis of the results of the systematic literature review on the topic of transformation rules between elements of UML class diagrams and OWL 2 constructs. The purpose of the analysis is to present the extent to which state-of-the-art transformation rules cover the semantics expressed in class diagrams. On the basis of the analysis, new transformation rules expressing the semantics not yet covered but expected from the point of view of domain modelling pragmatics have been defined. Results: The first result is the revision and extension of the transformation rules identified in the literature. The second original result is a proposition of verification rules necessary to check if a UML class diagram is compliant with the OWL 2 domain ontology. Conclusion: The proposed transformations can be used for automatic validation of compliance of UML class diagrams with respect to OWL 2 domain ontologies.

Adulteresses and fornicatresses in Serbian law in the first half of the XIX century

Opis:
During the first and second Serbian uprisings, under the influence of historic, social, cultural and ethnic processes which played a significant role in forming and developing the Serbian state, women were punished for the criminal acts of adultery and fornica- tion, which is proven by a large number of verdicts, but also by custom and canonical rules which stipulated specific sanctions in these cases. It can be concluded from mentioned verdicts in cases of adultery that the penal policy enforced by Karadjordje (First Uprising) was milder compared to the penal policy of Grand Duke Milosˇ (Second Uprising). At the time of Miloš’s rule, on the evidence of preserved rulings, it can be seen that in the period between 1825 and 1828 adulteresses faced corporal punishment involving 50 to 100 lashes of the whip and/or exile in cases where the adultery was committed with a Turk. The period between 1837 and 1843 is characterized by a milder penal policy similar to that from the time of Karadjordje’s rule (25 lashes of the whip), and even milder (10 lashes of the whip or 25 strokes of the stick) but with one difference – aside from corporal punishment jail terms were also frequently applied albeit for only short periods of time. As for the punishing of fornicatresses, as opposed to the punishing of adulteresses, there is a discrepancy between canonical and customary rules on one side and legal regulations on the other. Fornicators were most frequently awarded the sentence of whipping (12 to 50 lashes), but in several cases of fornicator deliberation, verdicts were recorded regardless of the circumstances involved. If the misbehavior of a girl was discovered before her marriage, she (and her entire family) would be exposed as a laughing-stock, the chances of a regular marriage became minimal, and the most violent reaction of the village was to stone or exile the offender. Sanctions stipulated by two legal systems – clerical canons and customary law norms, when it came to the criminal acts of adultery and fornication, were in essence almost identical in that both the church and the village stipulated the harshest fine for female transgressors – their excommunication. The basic sanctions imposed by the Orthodox Church against “fallen” female members of the community ranged from the mild – denial of communion over a certain period of time, to those which, aside from the holy communion, also denied a female transgressor the presence during the second part of liturgy after prayer for non-christened, and the anathema – excommunication, which included exclusion from the church community (this was practiced in the most severe cases). These were not fines in the true sense of the word, but were more like categories of the present spiritual state of a particular member of the church, regardless of the type of transgression committed. However, the “sinner” always had to repent and return back to the community. This was the true purpose of these penances. As far as the customary law is concerned, it is known that it developed under a certain set of circumstances. Serbia, when it fell under Turkish rule, lost its legislative continuity. In the absence of state regulations, the customary law, simultaneously with church law and under its significant influence, became the only orient in the regulation of basic social relations and at the same time, its protector and guardian. All actions of individuals which differed from established social norms fell under the impact of public criticism and condemnation and were sanctioned in an appropriate way. Excommunication from the church or social community for these women was more severe than the death sentence which was sometimes levied for some of these criminal acts.

The authors studied which allocations for apportionment problems have been obtained when (discrete) bankruptcy rules were applied to the associated bankruptcy problems. They have shown that the (dis-crete) constrained equal losses rule coincides with the greatest remainder method for apportionment problems. Furthermore, new properties related to governability have been proposed for apportionment methods. Finally, several apportionment methods satisfying governability properties have been applied to the case of the Spanish Elections in 2015.

Opis:
The paper gives an overview of the South African Corporate Leniency Policy which is a whistleblowing tool used by Competition agencies to detect and punish cartel behavior. The leniency applicant provides vital information to the competition authorities to fulfill the needs of this Policy. This information would be of great assistance to a claimant harmed by the cartel and who wishes to submit a claim for follow-on damages. Revealing this information results in serious implications for both leniency applicants and civil damages plaintiffs and poses a dilemma to Competition authorities. This paper questions whether the interest of the leniency applicant should be protected or should the information be handed over to the claimant to pursue a case for damages. After considering the status quo of the South African legal context, a survey of the EU and USA position on this is provided. The paper concludes on how a balance should be struck.
L’article donne un aperçu de la politique sud-africaine en matière de la clémence des entreprises qui est un outil d’alerte utilisé par les agences de compétition pour détecter et sanctionner le comportement de cartel. Le demandeur de clémence fournit les autorités de la concurrence en informations essentielles pour satisfaire les besoins de la présente politique. Ces informations seraient d’une grande aide à un prestataire lésé par le cartel et qui souhaite présenter une demande pour obtenir les dommages par la suite. La révélation de ces informations résulte en conséquences graves pour les deux demandeurs de clémence et les plaignants des dommages civils, et pose un dilemme aux autorités de la concurrence. Cet article pose la question si l’intérêt du demandeur de clémence doit être protégé ou peut-être l’information devrait être remise au demandeur afin de poursuivre une affaire de dommages-intérêts. Après avoir examiné le status quo du cadre juridique d’Afrique du Sud, une enquête de la position de l’UE et les Etats-Unis sur cette question est prévue. L’article se termine sur la façon dont un équilibre doit être trouvé

chronic kidney disease
Opis:
Chronic kidney disease is a general definition of kidney dysfunction that lasts more than 3 months. When chronic kidney disease is advanced, the kidneys are no longer able to cleanse the blood of toxins and harmful waste products and can no longer support the proper function of other organs. The disease can begin suddenly or develop latently over a long period of time without the presence of characteristic symptoms. The most common causes are other chronic diseases – diabetes and hypertension. Therefore, it is very important to diagnose the disease in early stages and opt for a suitable treatment - medication, diet and exercises to reduce its side effects. The purpose of this paper is to analyse and select those patient characteristics that may influence the prevalence of chronic kidney disease, as well as to extract classification rules and action rules that can be useful to medical professionals to efficiently and accurately diagnose patients with kidney chronic disease. The first step of the study was feature selection and evaluation of its effect on classification results. The study was repeated for four models – containing all available patient data, containing features identified by doctors as major factors in chronic kidney disease, and models containing features selected using Correlation Based Feature Selection and Chi-Square Test. Sequential Minimal Optimization and Multilayer Perceptron had the best performance for all four cases, with an average accuracy of 98.31% for SMO and 98.06% for Multilayer Perceptron, results that were confirmed by taking into consideration the F1-Score, for both algorithms was above 0.98. For all these models the classification rules are extracted. The final step was action rule extraction. The paper shows that appropriate data analysis allows for building models that can support doctors in diagnosing a disease and support their deci-sions on treatment. Action rules can be important guidelines for the doctors. They can reassure the doctor in his diagnosis or indicate new, previously unseen ways to cure the patient.

Opis:
Neurological disorders are diseases of the brain, spine and the nerves that connect them. There are more than 600 diseases of the nervous system, such as epilepsy, Parkinson's disease, brain tumors, and stroke as well as less familiar ones such as multiple sclerosis or frontotemporal dementia. The increasing capabilities of neurotechnologies are generating massive volumes of complex data at a rapid pace. Evaluating and diagnosing disorders of the nervous system is a complicated and complex task. Many of the same or similar symptoms happen in different combinations among the different disorders. This paper provides a survey of developed selected data mining methods in the area of neurological diseases diagnosis. This review will help experts to gain an understanding of how data mining techniques can assist them in neurological diseases diagnosis and patients treatment.

This paper discusses the use of the names of heresies: bogomilism, messalianism and the heresy of autoproscoptae in 14th century Bulgarian sources. The author underlines that the names of bogomilism and messalianism do not always refer to dualism. Two wider unknown examples of such use of the name “messalinism” are recalled. In the Pseudo-Zonaras Nomocanon (CIAI 1160), the name “messalianism” is treated as being equal to the “heresy of autoproscoptae”. In the Rule for hermits, messalians are presented not as heretics, but as monks disregarding their rules.

Opis:
In the paper the optimal design of forecasting contracts in principal-agent setting is investigated. It is assumed that the principal pays the agent (the forecaster) based on an announced forecast and an event that materializes next. Such a contract is called incentive compatible if the agent maximizes her payoff when she announces her true beliefs. This paper relaxes the assumption present in earlier works on this subject that agent’s beliefs are deterministic by allowing them to be random (i.e. stemming from estimation). It is shown that for binary or nominal events the principal can learn only expected values of agent’s predictions in an incentive compatible way independent of agent’s signal space. Additionally it is proven that incentive compatible payment schemes give the agent a strictly positive incentive to improve the precision of her estimates.

The paper presents four pillars of competition law that can be recognised in the European Union and Member States, namely EU competition law, national competition law sensu stricto, national competition law sensu largo and competition rules sensu largissimo. In order to demonstrate that this multi-faceted and complex system is able to work in an orderly manner, it is considered in relation to various concepts, particularly unity, uniformity and effectiveness. Nevertheless, the concept of unity serves as a focal point for the observations. The perspective of the EU single market plays a part also, enhancing the call for unity. With regard to discussed threats for unity, possible solutions are proposed in the final part of the article.
L’article traite de quatre piliers du droit de la concurrence qui existe dans l’Union européenne et dans les États membres, à savoir le droit de la concurrence de l’UE, le droit de la concurrence national au sens strict, le droit de la concurrence national au sens large et les règles de la concurrence au sens large. Afin de démontrer que ce système multiforme et complexe est capable de fonctionner de manière ordonnée, il est considéré en relation avec divers concepts, notamment l’unité, l’uniformité et l’efficacité. Néanmoins, le concept d’unité sert de point focal pour les observations. La perspective du marché unique de l’UE joue également un rôle, renforçant l’appel à l’unité. Dans la dernière partie de l’article, des solutions possibles aux menaces discutées pour l’unité sont proposées.

Opis:
In this paper we present a method for evaluating the importance of GO terms which compose multi-attribute rules. The rules are generated for the purpose of biological interpretation of gene groups. Each multi-attribute rule is a combination of GO terms and, based on relationships among them, one can obtain a functional description of gene groups. We present a method which allows evaluating the influence of a given GO term on the quality of a rule and the quality of a whole set of rules. For each GO term, we compute how big its influence on the quality of generated set of rules and therefore the quality of the obtained description is. Based on the computed quality of GO terms, we propose a new algorithm of rule induction in order to obtain a more synthetic and more accurate description of gene groups than the description obtained by initially determined rules. The obtained GO terms ranking and newly obtained rules provide additional information about the biological function of genes that compose the analyzed group of genes.

Opis:
Based on rough set theory many algorithms for rules extraction from data have been proposed. Decision rules can be obtained directly from a database. Some condition values may be unnecessary in a decision rule produced directly from the database. Such values can then be eliminated to create a more comprehensible (minimal) rule. Most of the algorithms that have been proposed to calculate minimal rules are based on rough set theory or machine learning. In our approach, in a post-processing stage, we apply the Apriori algorithm to reduce the decision rules obtained through rough sets. The set of dependencies thus obtained will help us discover irrelevant attribute values.

Opis:
Purpose: The purpose of this paper is to investigate whether the capital structure of stock exchange listed companies in individual countries of the Visegrad Group differs significantly, and whether these entities can be considered to be organizations implementing the principles of the golden and silver rules of accounting. Design/methodology/approach: The research hypotheses assumed were verified using appropriate statistical tools. Calculations were per-formed using the Gretl software and MS Excel. Findings: The basis for operating activity financing in the companies under examination mainly entailed equity. In practice, this means that most of the entities surveyed follow the silver, less frequently the golden (the more restrictive), rule of accounting. The results obtained for each country of the Visegrad Four differed significantly. The research conducted provides a basis for determining whether the golden and silver rules of accounting constitute factors affecting the decision-making regarding capital structure formation in companies listed in the Visegrad Group countries. The study covers companies listed in the four countries and provides a basis for further research in this area, with respect to both the sample size and the time series length. Research limitations/implications: The paper takes into account only listed companies, so its results do not explain capital structure behavior of other companies. The research is a contribution to further analyses of the capital structure, which covers all types of enterprises. Practical implications: The research conducted provides a basis for determining whether the golden and silver rules of accounting constitute factors affecting the decision-making regarding capital structure formation in companies listed in the Visegrad Group countries. The study covers companies listed in the four countries and provides a basis for further research in this area, with respect to both the sample size and the time series length. Originality/value: The most important principle of financing is that firms should try to match the characteristics of the financing as closely as possible to the characteristics of the assets being financed. Unfortunately, only a few studies on this subject can be found, especially internationally. Our research aims to fill a gap in the literature on the subject. It made possible to identify financing rules characterizing capital structure of the companies operating in different economic conditions. The study may be addressed to analysts, investors and managers of companies as well as researchers conducting research in corporate finance area.

Opis:
A knowledge discovery system is prone to yielding plenty of patterns, presented in the form of rules. Sifting through to identify useful and interesting patterns is a tedious and time consuming process. An important measure of interestingness is: whether or not the pattern can be used in the decision making process of a business to increase profit. Hence, actionable patterns, such as action rules, are desirable. Action rules may suggest actions to be taken based on the discovered knowledge. In this way contributing to business strategies and scientific research. The large amounts of knowledge in the form of rules presents a challenge of identifying the essence, the most important part, of high usability. We focus on decreasing the space of action rules through generalization. In this paper, we propose an improved method for discovering short descriptions of action rules. The new algorithm produces summaries by maximizing the diversity of rule pairs, and minimizing the cost of the suggested actions.

Opis:
A new approach to the modelling of various nature phenomena such as predator and prey ecological system, heat transport, spreading of oil slick and traffic flow is introduced. Cellular automata (CA) are discrete dynamical systems whose behaviour is completely specified in terms of simple local relations. They are mathematical models of spatialy distributed processes; however they can lead to an appropriate simulation of comlex dynamic processes. Applications to heat transfer and problems of environmental simulations are done. A discrete automaton model with fuzzy rules to simulate one-way traffic flow is also described. Results of simulations are consistent with phenomena observed in reality. It gives a base to propose the cellular automata tool as an option in modelling and solving problems of complex (and some times, not completely known) nature.
W pracy zaprezentowano metodę modelowania układów i zjawisk obserwowanych w przyrodzie, takich jak dynamika systemu ekologicznego drapieżnik-ofiara, przewodzenie ciepła, rozprzestrzenianie się plamy ropy naftowej po wycieku na wodzie czy ruch strumienia pojazdów na drodze miejskiej. Metodę oparto na tzw. automatach komórkowych, które są układami dyskretnymi o zachowaniach ściśle zdeterminowanych prostymi relacjami o charakterze lokalnym. Automaty komórkowe to matematyczne modele procesów przestrzennych, mogące z powodzeniem opisywać złożone zjawiska dynamiczne. W pracy przedstawiono aplikację do zagadnienia przewodzenia ciepła oraz kilku symulacji środowiskowych. Przedstawiono także model automatowy z regułami rozmytymi opisujący jednokierunkowy ruch pojazdów na drodze. Wyniki symulacji okazały się zgodne z obserwacjami rzeczywistych układów. Zachęcające rezultaty badań skłaniają do postrzegania automatów komórkowych jako efektywnej opcji w modelowaniu i rozwiązywaniu problemów o złożonej (czasem nie całkiem rozpoznanej) naturze.
