The Valley Baseball League is a collegiate summer baseball league with 11 teams playing 42 games between June and August. Producing a schedule has proved challenging for league management, because of the odd number of teams as well as a large number of league mandates and team-specific requests. As an amateur league with limited financial resources, there is pressure to best leverage the league schedule to maximize revenue for each team. A schedule generated by mathematical programming was enthusiastically adopted for the 2020 season and significantly outperformed previous manually produced schedules.

Purpose. Development of a method for forming an optimal portfolio of venture projects taking into account risks, uncertainty in initial data and limited financial resources. Methodology. To calculate the accuracy of forecasting prices, which are necessary for calculating the parameters of the stochastic optimization model for the formation of a portfolio of projects, we used the theory of random variables and regression analysis. The problem of choosing the optimal portfolio of venture projects was solved using stochastic mathematical programming. Findings. A model for creating an optimal portfolio of venture projects has been developed. It is a stochastic mathematical programming model that can be used to solve problems of investing in venture projects in the extractive industry. This model takes into account the risks associated with obtaining the expected income from the implementation of each venture project, the uncertainty in the initial data for calculating the income from the projects selected in the portfolio, as well as the limited funds required to finance the project portfolio. Originality. The stochastic optimization model for the formation of an optimal portfolio of projects, taking into account the peculiarities of venture projects, in particular, their high riskiness, has been significantly improved and adapted. Practical value. The proposed model for the formation of an optimal portfolio of venture projects can be used at mining enterprises, whose development strategy involves the implementation of innovative, high-risk projects. The use of this model in strategic planning will allow an enterprise to receive the maximum income from venture projects in the face of a lack of financial resources, as well as instability of the innovation market.

The article analyzes the situation with attraction of foreign direct investments (FDI) into the Russian Federation. Sharply increased inflow of international financial resources into national economy has highlighted the problem of definitions, the reasons of this phenomenon and its economic contents. The article considers methodological aspects and economic essence of modern FDI. Special accent is made on the estimation of the situation with their attraction into Russia, FDI structure and effectiveness. The conclusions about basic directions of the increase of their effectiveness in the Russian economy are formulated.

Opioid Detoxification

Materials and Methods. Published articles on the opioid abuse and methods of opioid detoxification were identified by searching medical databases, using corresponding literature and were also searched manually for applicable papers. The search was limited to articles published from 1985 through 2014. Results. Opioid dependence determine pathophysiologic changes in the dopaminergic pathways of the organism, as well as the alterations in the stress-responsive hypothalamic-pituitary-adrenal axis. The usage of opioid antagonists in the early stages of withdrawal, can lead the effectiveness of opioid detoxification to 100%. Rapid opioid detoxification do not remove all the symptoms of abstinence. Negative aspects, concerning the procedure, while using prevention, can be reduced to the minimum risk. Rapid opioid detoxification, comparing it with Ultrarapid opioid detoxification procedure, diverges as less financial resources and a lower risk containing technique. Conclusions. Use of antagonists may reduce the duration of withdrawal, thus reducing the overall severity of withdrawal and increasing the chances of successful completion. This technique facilitates commencement of naltrexone treatment. Dosing regimens used in clinical trials vary. Subsequent results do not correlate with the methods of detoxification.

Subject. The article addresses leader companies of the e-commerce market in terms of sales and capitalization, that make their financial statements publicly available. Objectives. The aim is to identify special aspects of capital structure management policies of the largest e-commerce players based on ratio analysis. Methods. The study employs general scientific methods of research. Results. The paper reveals the specifics of capital structure management of the global e-commerce market leaders. The leading companies prefer an aggressive approach to the formation of their capital structure, increasing the volume of borrowed capital in comparison with their equity. The management of companies tries to provide a moderate approach to capital structure management and debt servicing, demonstrating the ability to repay debts in a timely manner. Aggressive capital structure policy is conditioned by specific activities of e-commerce companies, requiring constant search for and attraction of additional financial resources for improving production processes by management. Conclusions. Key players have an aggressive capital structure policy. This feature is necessitated by the need to systematically attract additional financing to expand the business, increase sales volumes, capture and create new markets. E-commerce companies have to constantly improve technology, logistics processes, and render a good and excellent customer service.
