Cкрининги I этапа диспансеризации: систематический обзор долгосрочной эффективности
Objective — to make a systematic search and an analysis of evidence for the long-term population-based efficiency of screenings and other measures implemented in the framework of Stage 1 screening during periodical health check in the Russian Federation according to the Order №36ан dated 2015. Material and methods. A systematic search was carried out independently by two authors in four databases: Scientific Electronic Library, Cochrane Library, Medline/PubMed, and USPSTF. Systematic reviews are an investigated publications type. The criteria for the efficacy of screening were overall and specific mortality and disability. The methodological quality of systematic reviews was assessed by two authors by the procedure using the international AMSTAR questionnaire. Results. Only a fecal occult blood test and abdominal aorta ultrasonography have a scientific justification as screening methods in certain age and gender populations by the criterion for reducing the specific mortality, while the methodological quality of systematic reviews is high and medium/high. The efficiency of mammography in women has not been proven in high methodological quality studies.
In the present paper we have hypothesized an explanation for the fact that the evaluation
of the social impact of law is modeled predominantly by the economic efficiency concept.
Considering the early stages of the concept’s development, we try to make it more
intelligible to the European lawyers.
Electron bunching processes in a carcinotrode (backward_wave oscillator with self_modulation of electron emission) operating in the high_efficiency regime determined previously are investigated. The possibility of obtaining an efficiency of about 80% is explained from the physical viewpoint.
There is by now a large literature arguing that auctions with a variety of after-market interactions may not yield an efficient allocation of the objects for sale, especially when the bidders impose strong negative externalities upon each other. In this note, we argue that these inefficiencies can be avoided by asking bidders prior to the auction to submit any publicly observable payment they would like to make. These payments, so-called flexible entry fees, do not affect the allocation decision of the auctioneer. We show that auctions with flexible entry fees have a fully revealing equilibrium where bidders signal their type before the auction itself takes place.
The main purpose of this monograph is to identify the key factors of risk man- agement efficiency of firm, whose management is able to increase the investment attractiveness of the business in general, as well as the formation of an effective or- ganizational risk management model that allows, on the one hand - to provide reliable protection for companies against unexpected losses, on the other hand - to make a risk management tool for the creation of corporate value. This monograph presents the organization of risk management in accordance with the latest regulatory require- ments. In the monograph authors provide a developed methods for evaluating the effectiveness of existing mechanisms of risk management, based on a representative theoretical review of the scientific literature of leading researchers in the field of risk management and internal control. In addition, an algorithm for evaluating the econom- ic and investment efficiency of the risk management is given, that takes into account the existing methods of performance evaluation, as well as recommendations on the organization of internal compliance as a tool ensuring the consistency of individual and corporate interests of the company. Most of the conclusions and positions pre- sented in the book, confirmed by empirical calculations on the example of Russian and international companies.
In the article authors use the vital birh and death registration data on 10 regions exctracted from the Rosstat database to evaluate an input of international migrant into Russian fertility and mortality levels.
The concept and aim of evidence-based entrepreneurship (EBE) is discussed as a strategy to overcome the divide between knowledge developed in the field of entrepreneurship and its use in practice. We argue that meta-analyses can and should be used in entrepreneurship research (and that it should also be used for qualitative work).
We address the external effects on public sector efficiency measures acquired using Data Envelopment Analysis. We use the health care system in Russian regions in 2011 to evaluate modern approaches to accounting for external effects. We propose a promising method of correcting DEA efficiency measures. Despite the multiple advantages DEA offers, the usage of this approach carries with it a number of methodological difficulties. Accounting for multiple factors of efficiency calls for more complex methods, among which the most promising are DMU clustering and calculating local production possibility frontiers. Using regression models for estimate correction requires further study due to possible systematic errors during estimation. A mixture of data correction and DMU clustering together with multi-stage DEA seems most promising at the moment. Analyzing several stages of transforming society’s resources into social welfare will allow for picking out the weak points in a state agency’s work.
