The economic approach to designing anticorruption institutions

Contemporary economic analysis of corrupt behaviour requires practical consideration of the issues concerning projecting of social anti-corruption institutions. The economic science has accumulated sufficient practical experience of institutional construction in society, for instance approaches provided by K. Sunstein’s and E. Ostrom. The requirement of reasonability in managing economic interactions makes the society refuse from the dichotomy of market (anarchical, spontaneous) and non-market (hierarchical) institutions. The same tendency can be observed in arranging anti-corruption struggle in state management. Both approaches - aimed at creating fixed vertical hierarchy as well as at creating competition at the lowest bureaucratic level - are inappropriate. That is why anticorruption institutions arranging should be based on economic models of rational criminal and citizens involvement in law enforcement activity. These models enable to harmonize state dirigisme related to the state management ex ante with basic provision of laissez-faire doctrine – personal motives of people’s behaviour. Standard economic supply and demand model has shown inelasticity of corruption crimes supply in Russia. Non-price determinants (cultural norms, “tabu”) seem to be more significant in motivating corruption behaviour than price determinants (seriousness and probability of punishment). Economic characteristics of elasticity and inelasticity of supply and demand in the model of involvement into law enforcement activity enable to create strategy of developing social anti-corruption institutions

Employment structure transformation through economic activity types perspective

The present study was conducted to identify the reasons in modern information society that caused significant changes in the labor market particularly in its industrial structure through the perspective of individuals employed in real and service sectors. The analysis of the employed population`s statistical sample by economic activity type in enlarged groups of industrial and non-industrial spheres of activity over the past 20 years has shown that scientific and technological transformations have led to a significant shift in the employment structure. The research used statistical data comparison of economic activity types and the ratio of the regions employed in real and service sectors. New types of economic activity are emerging and start prevailing inherent exclusively in the current state of economy in the context of digitalization. A significant structural shift has been revealed in the course of the analysis of the employed population by the enlarged industry affiliation, which demonstrates diametrically opposite positions in the overall structure of employment. The resulting ratio allows us to propose and apply the coefficient of the employment structure, demonstrating a multiplier effect on identifying such jobs creation and preservation of which leads to further employment provisioning. The obtained tool allows managing population employment as well as related social and economic processes as migration outflow and population growth in all age groups, population reproduction, expansion and improvement of educational and health services in a particular territory. In addition, application of the developed employment structure tool allows estimating the amount of investment required to solve these issues

Artificial optoelectronic spiking neurons with laser-coupled resonant tunnelling diode systems

We report a spiking artificial optoelectronic neuron based on a resonant tunnelling diode (RTD) coupled to a photodetector (receiver) and a vertical cavity surface emitting laser (VCSEL, transmitter). We experimentally realize this O/E/O system, and demonstrate optical spiking with a well-defined, adjustable excitability threshold

A prospective randomized controlled trial of bone metabolism in patients with charcot foot

BACKGROUND: Diabetic neuroosteoarthropathy (DNOAP, Charcot’s foot) - is a progressive destructive inflammatory disease of the osteoarticular apparatus of the foot, untimely and inadequate treatment of which can lead to the formation of gross deformities. More often, DNOAP is unilateral, bilateral lesion is relatively rare. It is not always possible to trace the relationship between the debut of DNOAP with trauma and chronic hyperglycemia. There is data demonstrating the role of individual pro-inflammatory factors in the pathogenesis of DNOAP, however, studies combining the evaluation of various metabolic markers of Charcot’s foot formation are currently extremely poor. AIM: To evaluate the hormonal and metabolic markers of bone formation and resorption in patients with DNOAP and without this diabetic complication. METHODS: A prospective, controlled trial included 70 patients with type 2 diabetes mellitus (37 men and 43 women) who formed 2 groups: group 1 included patients with DNOAP, group 2 was formed by patients with diabetes without foot skeleton damage. All patients underwent a study of 1,25-OH-vitamin D, sclerostin, pro-MMP-1, C-terminal propeptide type 1 collagen (PICP), type 1 collagen, osteocalcin, PTH, 25-OH-vitamin D, beta-cross-slaps. RESULTS: The results of the studies confirmed the presence of vitamin D deficiency in all patients with diabetes mellitus included in the study, revealed the absence of statistically significant differences between the groups in the values of sclerostin, pro-MMP-1; 25-OH-vitamin D, type I collagen, and osteocalcin (p > 0.05). However, significant differences were found in the 1.25-OH vitamin D levels: patients with DNOAP presented the lower rates of 1,25-OH-vitamin D in comparison to control group (p <0.05). Beta-cross and PICP levels were significantly higher in DNOAP patients as well (p <0.05). Those findings show the more severe collagen degradation in patients with DNOAP and can be the genetically predisposed cause of DNOAP development. Though further studies are needed. CONCLUSION: In patients with DNOAP a decrease in 1,25-OH-vitamin D levels was found, as well as the alteration of the synthesis and destruction of collagen (beta-cross-slaps and PICP) compared to patients with diabetes mellitus without osteoarticular disorders

Tuneable presynaptic weighting in optoelectronic spiking neurons built with laser-coupled resonant tunneling diodes

Optoelectronic spiking neurons are regarded as highly promising systems for novel light-powered neuromorphic computing hardware. Here, we investigate an optoelectronic (O/E/O) spiking neuron built with an excitable resonant tunnelling diode (RTD) coupled to a photodetector and a vertical-cavity surface-emitting laser (VCSEL). This work provides the first experimental report on the control of the amplitude (weighting factor) of the fired optical spikes directly in the neuron, introducing a simple way for presynaptic spike amplitude tuning. Notably, a very simple mechanism (the control of VCSEL bias) is used to tune the amplitude of the spikes fired by the optoelectronic neuron, hence enabling an easy and high-speed option for the weighting of optical spiking signals in future interconnected photonic spike-processing nodes. Furthermore, we validate the feasibility of this layout using a simulation of a monolithically-integrated, RTD-powered, nanoscale optoelectronic spiking neuron model, confirming the system's potential for delivering weighted optical spiking signals at very high speeds (GHz firing rates). These results demonstrate the high degree of flexibility of RTD-based artificial optoelectronic spiking neurons and highlight their potential towards compact, high-speed and low-energy photonic spiking neural networks for use in future, light-enabled neuromorphic hardware

Artificial optoelectronic spiking neuron based on a resonant tunnelling diode coupled to a vertical cavity surface emitting laser

Excitable optoelectronic devices represent one of the key building blocks for implementation of artificial spiking neurons in neuromorphic (brain-inspired) photonic systems. This work introduces and experimentally investigates an opto-electro-optical (O/E/O) artificial neuron built with a resonant tunnelling diode (RTD) coupled to a photodetector as a receiver and a vertical cavity surface emitting laser as a transmitter. We demonstrate a well-defined excitability threshold, above which the neuron produces optical spiking responses with characteristic neural-like refractory period. We utilise its fan-in capability to perform in-device coincidence detection (logical AND) and exclusive logical OR (XOR) tasks. These results provide first experimental validation of deterministic triggering and tasks in an RTD-based spiking optoelectronic neuron with both input and output optical (I/O) terminals. Furthermore, we also investigate in simulation the prospects of the proposed system for nanophotonic implementation in a monolithic design combining a nanoscale RTD element and a nanolaser; therefore demonstrating the potential of integrated RTD-based excitable nodes for low footprint, high-speed optoelectronic spiking neurons in future neuromorphic photonic hardware
