The paper presents results of mapping and visualization of financial monitoring data. Measures of deviant activity of financial monitoring objects for the purpose of mapping have been received. The proposed solution can serve as a powerful tool to support the adoption of strategic decisions and macro analysis of the situation in the field of financial monitoring. The approaches proposed in the article to the processing of state data make it possible to implement a new methodological approach to information and analytical support for managerial decision-making in assessing the situation in the field of financial monitoring. The subject of financial monitoring was simulated and the mathematical and methodological tools were selected to solve the problem of mapping deviant economic entities, the simulation result is an infographic of the geographical component of laundering criminal proceeds. To map information about financial monitoring objects, it is necessary to rank them. However, the objects of financial monitoring – business entities, professional participants in the securities market – are described by sets of characteristics, i.e. essentially are objects of vector nature. In mathematics, the ordinal relations for vectors, as is known, are not defined.


The article provides a theoretical justification of necessity to create an investment guarantee fund for the Ukrainian securities market. In the article the foreign experience of the functioning of similar funds, their principles and peculiarities of the organization were emphasized. In particular, the funds of Estonia and Lithuania were analyzed. The purpose of such Guarantee Funds is to provide protection for investors through an investment organization, in case of failure of the investment organization. In order to achieve these goals, the Funds accumulate invest funds of financial resources in government securities and securities of central banks, and in the course of an insurance event, they pay insurance premiums in due time. In the article, it is noted that the object of investors protection is not investment risk, it means, the probability of loss because the investment will not bring profit or loss of value. The models of Estonia and Lithuania show a universal institution that reflects the protection of the clients’ interests of credit institutions (or depositors), clients of investment organizations (or investors), owners of mandatory pension funds shares and insurers who have entered into pension contracts with insurers. Based on the study of model and features in other countries, the authors proposed prototype of structure of a similar institution in Ukraine – «Fund for the Guarantee of Individual Deposits and Investments». One of the main bases is anticipated that such an institution should have a higher reimbursement rate for participants, the functionality and consistency of work with funds of accumulated financial resources will be analogous to foreign models. The management of the Fund will be formed by delegating to it representatives of various government agencies and self-regulatory organizations that will ensure real transparency and objective decision-making of the Fund.

AbstractRahnev & Denison (R&D) argue against normative theories and in favor of a more descriptive “standard observer model” of perceptual decision making. We agree with the authors in many respects, but we argue that optimality (specifically, reward-rate maximization) has proved demonstrably useful as a hypothesis, contrary to the authors’ claims.

AbstractThe target article uses a mathematical framework derived from Bayesian decision making to demonstrate suboptimal decision making but then attributes psychological reality to the framework components. Rahnev & Denison's (R&D) positive proposal thus risks ignoring plausible psychological theories that could implement complex perceptual decision making. We must be careful not to slide from success with an analytical tool to the reality of the tool components.

AbstractIntuitions guide decision-making, and looking to the evolutionary history of humans illuminates why some behavioral responses are more intuitive than others. Yet a place remains for cognitive processes to second-guess intuitive responses – that is, to be reflective – and individual differences abound in automatic, intuitive processing as well.

Abstract Gilead et al. offer a thoughtful and much-needed treatment of abstraction. However, it fails to build on an extensive literature on abstraction, representational diversity, neurocognition, and psychopathology that provides important constraints and alternative evidence-based conceptions. We draw on conceptions in software engineering, socio-technical systems engineering, and a neurocognitive theory with abstract representations of gist at its core, fuzzy-trace theory.
