Mathematical modeling is a convenient way for characterization of complex ecosystems. This approach was applied to study the dynamics of zooplankton in Lake Sevan (Armenia) at different stages of anthropogenic eutrophication with the use of a novel method called discrete modeling of dynamical systems with feedback (DMDS). Simulation demonstrated that the application of this method helps in characterization of inter- and intra-component relationships in a natural ecosystem. This method describes all possible pairwise inter-component relationships like “plus–plus,” “minus–minus,” “plus–minus,” “plus–zero,” “minus–zero,” (...) and “zero–zero” that occur in most ecosystems. Based on the results, a working hypothesis was formulated. It was found that the sensitivity to weak external influence in zooplanktons was the greatest during the mid period of eutrophication in Lake Sevan, whereas in the final stages of eutrophication, an outbreak in the biomass production of cyanobacteria was evident. To support this approach, a weak external disturbance in the form of magnetic storm was used to see its effect on species Daphnia longispina sevanica. A statistically significant correlation between the frequency of magnetic storms and the number of this species was revealed and an increase in the number of toxic cyanobacteria species as a consequence of eutrophication. This paper, for the first time, suggests a DMDS method, to diagnose impact of anthropogenic eutrophication on environment. (shrink)

The state-of-art research in the field of life’s organization confronts the need to investigate a number of interacting components, their properties and conditions of sustainable behaviour within a natural system. In biology, ecology and life sciences, the performance of such stable system is usually related to homeostasis, a property of the system to actively regulate its state within a certain allowable limits. In our previous work, we proposed a deterministic model for systems’ homeostasis. The model was based on dynamical system’s (...) theory and pairwise relationships of competition, amensalism and antagonism taken from theoretical biology and ecology. However, the present paper proposes a different dimension to our previous results based on the same model. In this paper, we introduce the influence of inter-component relationships in a system, wherein the impact is characterized by direction (neutral, positive, or negative) as well as its (absolute) value, or strength. This makes the model stochastic which, in our opinion, is more consistent with real-world elements affected by various random factors. The case study includes two examples from areas of hydrobiology and medicine. The models acquired for these cases enabled us to propose a convincing explanation for corresponding phenomena identified by different types of natural systems. (shrink)

I develop and test a multilevel trust-based model of ethical public leadership, which links ethical leadership, trust and leadership outcomes both within and across organizational levels. I examine how both ethical leadership and trust relate to employee well-being and satisfaction, group organizational citizenship behaviour and perceived organizational performance. The findings, based on data collected from an online quantitative survey conducted in three local councils of the north east of England, provide evidence in support of positive relationships between ethical leadership and (...) employees’ trust in leaders at multiple levels. This trust is in turn shown to influence employees’ attitudes, behaviours and cognitions. (shrink)

Author's answers to questions on Buddhist philosophy, posed to him by some foreign scholars.

Following Kit Fine (2007), we can say that the de jure pair represent the referent as the same while the second one does not do so. There are roughly three ways of capturing this difference. One could say that de jure coreference between two expression occurrences happen because (a) the occurrences have identical meanings, (b) they have identical syntactic properties, or (c) they enter into a semantic relation not grounded in identity of meaning or syntax. In what follows, I give (...) some reason to think that de jure coreference is not a transitive relation. As a consequence, we can rule out (a) and (b) just on these grounds alone (since identity is a transitive relation). (c) then looks promising. I argue that this gives further support for a relationist semantics along the lines of what Kit Fine has proposed. (shrink)
