Blood groups, erythrocyte antigens, and transfusion are fundamental areas of medicine and are related to many disciplines of science like hematology, immunology, surgery, and genetics. This book is a collection of information related to blood groups and transfusion, and a practical resource for all concerned physicians. The book is divided into two sections. The first section includes chapters on blood transfusion reactions and hemolytic disease of the fetus. The second section includes information for the future perspectives of blood group antigens. This book will be a stepping stone for scientists who are rapidly advancing their science journey.

This book examines how Russia, the world’s most complicated country, is governed. As it resumes its place at the centre of global affairs, the book explores Russia’s overarching strategies, and how it organizes itself (or not) in policy areas ranging from foreign policy and national security to health care, education, immigration, science, sport, agriculture, the environment and criminal justice. The book also discusses the structures and institutions on which Russia relies in order to deliver its goals in these areas of national life, as well as what’s to be done, in policy terms, to improve the country’s performance in its first post-Soviet century. Edited by Irvin Studin, the book includes contributions from a tremendous list of Russia’s leading thinkers and specialists, including Alexei Kudrin, Vladimir Mau, Alexander Auzan, Simon Kordonsky, Fyodor Lukyanov, Natalia Zubarevich and Andrey Melville.

The authors proposed and mathematically described model of a new type of the Fermi-Pasta-Ulam recurrence (the FPU auto recurrence) and hypothesized an adequate description of the heart's electrical dynamics within the observed phenomenon. The dynamics of the FPU auto recurrence making appropriate electrical dynamics of the normal functioning of the heart in the form of an electrocardiogram (ECG) was obtained by a computer model study. The model solutions in the form of the FPU auto recurrence – ECG Fourier spectrum were evaluated for resistance to external disturbances in the form of random effects, as well as periodic perturbation at a frequency close to the heart beating rate of about 1 Hz. In addition, in order to simulate the dynamics of myocardial infarction model, studied the effect of the surface area of the myocardium on the stability and shape of the auto recurrence – ECG spectrum. It has been found that the intense external disturbing periodic impacts at a frequency of about 1 Hz lead to a sharp disturbance spectrum shape FPU auto recurrence – ECG structure. In addition, the decrease in the surface of the myocardium by 50% in the model led to the destruction of structures of the auto recurrence – ECG, which corresponds to the state of atrial myocardium. Research models have revealed a hypothetical basis of coronary heart disease in the form of increasing the energy of high-frequency harmonics spectrum of the auto recurrence by reducing the energy of low-frequency harmonic spectrum of the auto recurrence, which ultimately leads to a sharp decrease in myocardial contractility. In order to test the hypothesis has been studied more than 20,000 ECGs both healthy people and patients with cardiovascular disease. As a result of these studies, it was found that the dynamics of the electrical activity of normal functioning of the heart can be interpreted by the display of the detected by authors the FPU auto recurrence, and coronary heart disease is a violation of the energy ratio between the low and high frequency harmonics of the FPU auto recurrence Fourier spectrum equal to the ECG spectrum. Thus, the hypothesis has been confirmed.

Adequate assessment of individual functional motor potentials is important for developing appropriate rehabilitation strategies in ischemic stroke [1]. Microstructural changes in corticospinal tract (CST) and corpus callosum (CC) were repeatedly correlated to post-stroke outcome [2, 3]. However, relationship between them and functional recovery remains unclear. Here we investigated relationship between integrity of CST and CC assessed with diffusion tensor imaging (DTI) and brain functional state assessed with navigated transcranial magnetic stimulation (nTMS) in chronic ischemic supratentorial stroke.

The present volume is the fourth issue of the Yearbook series entitled ‘Evolution’. The title of the present volume is ‘From Big Bang to Nanorobots’. In this way we demonstrate that all phases of evolution and Big History are covered in the articles of the present Yearbook. Several articles also present the forecasts about future development.

The main objective of our Yearbook as well as of the previous issues is the creation of a unified interdisciplinary field of research in which the scientists specializing in different disciplines could work within the framework of unified or similar paradigms, using the common terminology and searching for common rules, tendencies and regularities. At the same time for the formation of such an integrated field one should use all available opportunities: theories, laws and methods. In the present volume, a number of such approaches are used.

The volume consists of four sections: Universal Evolutionary Principles; Biosocial Evolution, Ecological Aspects, and Consciousness; Projects for the Future; In Memoriam.

This Yearbook will be useful both for those who study interdisciplinary macroproblems and for specialists working in focused directions, as well as for those who are interested in evolutionary issues of Cosmology, Biology, History, Anthropology, Economics and other areas of study. More than that, this edition will challenge and excite your vision of your own life and the new discoveries going on around us!

In the context of global efforts to move towards universal coverage in health systems, this report reviews health financing reforms in the Republic of Moldova and looks in particular at how the population´s access to health services has been affected. In 2004, as has been widely documented elsewhere, wholesale reforms were made to the way in which government funds were used to fund health services, shifting the system overnight from a highly fragmented and inflexible one, to one in which funds for the health sector were pooled nationally, allowing improved risk-sharing as a result of greater flexibility to allocate funds in line with health needs. A new source of funding in the form of a payroll tax for health was also introduced directly leading to a growth in total levels of government health spending. A second phase of reforms starting in 2009 addressed the issue of gaps in population coverage under mandatory health insurance, with legislative measures taken to ensure that all citizens of Moldova had access to primary health care, and to ensure that the poor receive subsidized health insurance. Fiscal constraints have limited the full implementation of these reforms however. Moldova has shown that it is prepared to tackle difficult policy issues head on and has articulated clear goals for the sector. In particular, the Roadmap “Accelerating Reforms: addressing the needs of the health area through investment policies” approved on 1 March 2012, lays a clear agenda for the next phase or priority reforms focusing on principally on service delivery reorganization but also on health financing. This is the correct focus given that progress on a number of priority indicators such as equity in access to services and financial protection has been limited in recent years. This report summarizes the main impact of health financing reforms to date and agrees with the Roadmap about the major challenges for the coming decade, in particular the need to address inefficiencies in service delivery, but also to ensure that the close link between guaranteed benefits and available funding is maintained in future policy decisions.

The spatial accuracy of transcranial magnetic stimulation (TMS) may be as small as a few millimeters. Despite such great potential, navigated TMS (nTMS) mapping is still underused for the assessment of motor plasticity, particularly in clinical settings. Here, we investigate the within-limb somatotopy gradient as well as absolute and relative reliability of three hand muscle cortical representations (MCRs) using a comprehensive grid-based sulcus-informed nTMS motor mapping. We enrolled 22 young healthy male volunteers. Two nTMS mapping sessions were separated by 5–10 days. Motor evoked potentials were obtained from abductor pollicis brevis (APB), abductor digiti minimi, and extensor digitorum communis. In addition to individual MRI-based analysis, we studied normalized MNI MCRs. For the reliability assessment, we calculated intraclass correlation and the smallest detectable change. Our results revealed a somatotopy gradient reflected by APB MCR having the most lateral location. Reliability analysis showed that the commonly used metrics of MCRs, such as areas, volumes, centers of gravity (COGs), and hotspots had a high relative and low absolute reliability for all three muscles. For within-limb TMS somatotopy, the most common metrics such as the shifts between MCR COGs and hotspots had poor relative reliability. However, overlaps between different muscle MCRs were highly reliable. We, thus, provide novel evidence that inter-muscle MCR interaction can be reliably traced using MCR overlaps while shifts between the COGs and hotspots of different MCRs are not suitable for this purpose. Our results have implications for the interpretation of nTMS motor mapping results in healthy subjects and patients with neurological conditions.

In many rare disease Phase II clinical trials, two objectives are of interest to an investigator: maximising the statistical power and maximising the number of patients responding to the treatment. These two objectives are competing, therefore, clinical trial designs offering a balance between them are needed. Recently, it was argued that response-adaptive designs such as families of multi-arm bandit (MAB) methods could provide the means for achieving this balance. Furthermore, response-adaptive designs based on a concept of context-dependent (weighted) information criteria were recently proposed with a focus on Shannon’s differential entropy. The information-theoretic designs based on the weighted Renyi, Tsallis and Fisher informations are also proposed. Due to built-in parameters of these novel designs, the balance between the statistical power and the number of patients that respond to the treatment can be tuned explicitly. The asymptotic properties of these measures are studied in order to construct intuitive criteria for arm selection. A comprehensive simulation study shows that using the exact criteria over asymptotic ones or using information measures with more parameters, namely Renyi and Tsallis entropies, brings no sufficient gain in terms of the power or proportion of patients allocated to superior treatments. The proposed designs based on information-theoretical criteria are compared to several alternative approaches. For example, via tuning of the built-in parameter, one can find designs with powercomparable to the fixed equal randomisation’s but a greater number of patients responded in the trials.

The review analyzes the potential advantages and problems associated with using HIF prolyl hydroxylase inhibitors as a treatment for COVID-19. HIF prolyl hydroxylase inhibitors are known to boost endogenous erythropoietin (Epo) and activate erythropoiesis by stabilizing and activating the hypoxia inducible factor (HIF). Recombinant Epo treatment has anti-inflammatory and healing properties, and thus, very likely, will be beneficial for moderate to severe cases of COVID-19. However, HIF PHD inhibition may have a significantly broader effect, in addition to stimulating the endogenous Epo production. The analysis of HIF target genes reveals that some HIF-targets, such as furin, could play a negative role with respect to viral entry. On the other hand, HIF prolyl hydroxylase inhibitors counteract ferroptosis, the process recently implicated in vessel damage during the later stages of COVID-19. Therefore, HIF prolyl hydroxylase inhibitors may serve as a promising treatment of COVID-19 complications, but they are unlikely to aid in the prevention of the initial stages of infection.

Background and Purpose Despite the continuing efforts in multimodal assessment of the motor system after stroke, conclusive findings on the complementarity of functional and structural metrics of the corticospinal tract (CST) integrity and the role of the contralesional hemisphere are still missing. The aim of this work was to find the best combination of the motor system parameters, allowing classification of patients into three predefined groups of upper limb motor recovery.

Methods 35 chronic ischemic stroke patients (47 [26–66] y.o., 29 [6–58] months post-stroke) with only supratentorial lesion and unilateral upper extremity weakness were enrolled. Patients were divided into three groups depending on the upper limb motor recovery. Non-parametric statistical tests and regression analysis were used to investigate the relationships among structural and functional motor system parameters, probed by diffusion tensor imaging (DTI) and transcranial magnetic stimulation (TMS). In addition, stratification rules were tested, using a decision tree classifier to identify parameters explaining motor recovery.

Results Fractional anisotropy (FA) ratio in the internal capsule (IC) and absence/presence of motor evoked potentials (MEPs), were equally discriminative of the worst motor outcome group (96% accuracy). MEP presence diverged for two investigated hand muscles. Concurrently, for the three recovery groups’ classification, the best parameter combination was: IC FA ratio and Fréchet distance between the contralesional and ipsilesional CST FA profiles (91% accuracy). No other metrics had any additional value for patients’ classification.

Conclusions This study demonstrates that IC FA ratio and MEPs absence are equally important markers for poor recovery. Importantly, we found that MEPs should be controlled in more than one hand muscle. Finally, we show that better separation between different motor recovery groups may be achieved when considering the whole CST FA profile.

The Keap1-Nrf2 signaling axis is a validated and promising target for cellular defense and survival pathways. This minireview discusses the potential off-target effects and their impact on future drug development originating from Keap1-targeting small molecules that function as displacement activators of the redox-sensitive transcription factor Nrf2. We argue that small-molecule displacement activators, similarly to electrophiles, will release both Nrf2 and other Keap1 client proteins from the ubiquitin ligase complex. This non-specificity is likely unavoidable and may result in off-target effects during Nrf2 activation by targeting Keap1. The small molecule displacement activators may also target Kelch domains in proteins other than Keap1, causing additional off-target effects unless designed to ensure specificity for the Kelch domain only in Keap1. A potentially promising and alternative therapeutic approach to overcome this non-specificity emerging from targeting Keap1 is to inhibit the Nrf2 repressor Bach1 for constitutive activation of the Nrf2 pathway and bypass the Keap1-Nrf2 complex.

Question:Paired pulse transcranial magnetic stimulation(ppTMS) is a common approach to probe cortical excitatory and inhi-bitory processes [a]. ppTMS paradigms can be classified by the inter-stimulus interval (ISI) to long and short interval ppTMS. It isassumed, that short interval ppTMS phenomena such as short-inter-val cortical inhibition phenomenon (SICI) are rather focal and arediscussed in terms of surround inhibition in the motor cortex [b].Longer interval ppTMS phenomena are believed to be based on morewidespread trans-synaptic mechanisms[c]. The topographic aspectsof these ppTMS phenomena are not fully understood yet. The associ-ation of the various ppTMS phenomena studied in different musclesof the same limb remains unexplored. The aim of this study was toassess the interaction of ppTMS phenomena, probed in differentupper limb muscles. We hypothesized that the correlation amongthe different hand muscles within the ppTMS phenomenon willdepend on the ppTMS ISI.Methods:19 healthy right-handed volunteers participated in thestudy (15 females, 18–30 y.o.). Four ppTMS phenomena (SICI/LICI –short-interval/long-interval intracortical inhibition, SICF – short nterval intracortical facilitation and ICF – intracortical facilitation)were probed using navigated TMS (MagPro X100, Localite TMSNavigator) applied at the APB hotspot of the left primary motor cor-tex. We registered motor evoked potentials (MEPs) from four rightupper limb muscles: abductor pollicis brevis (APB), extensor digito-rum communis (EDC), abductor digiti minimi (ADM) and biceps bra-chii (BB). Spearman’s rank correlation coefficient was calculated toevaluate an association of inter-muscle ppTMS phenomena.Multiple comparisons were controlled with the FDR. For the finalanalysis we considered only correlations between spatially sepa-rated muscles with sufficiently high amplitudes of MEPs during sin-gle pulse TMS.Results:SICI, ICF and LICI phenomena correlated significantlyamong all the considered muscles‘ pairs. SICI for APBEDC:r=0.793,p= 0.000; for ADMEDC:r= 0.905,p= 0.000. ICF for APBEDC:r= 0.639,p= 0.000; for ADMEDC:r= 0.639,p= 0.000.SICF for APBEDC:r= 0.423,p> 0.05; for ADMEDC:r= 0.779,p= 0.000. LICI for APBEDC:r= 0.575,p= 0.000; for ADMEDC:r= 0.704,p= 0.004.Conclusion:In agreement with the previous data, we did not finda clear association among different ppTMS phenomena. In contrastto our hypothesis, there is no link between ISI and the correlationof the same ppTMS phenomenon among muscles. The lack of thecorrelation between APB and EDC in SICF might be explained bySICF peculiar mechanism through the superposition of D-and I-waves [d]; and by a specialized functionality of the thenar, compar-ing to hypothenar muscles, – the idea which should be further ver-ified in the following experiments.

Epigenetic alterations represent promising therapeutic targets in cancer treatment. Recently it was revealed that small molecules have the potential to act as microRNA silencers. Capacity to bind the discrete stem-looped structure of pre-miR-21 and prevent its maturation opens opportunities to utilize such compounds for the prevention of initiation, progression, and chemoresistance of cancer. Molecular simulations performed earlier identified 3,3′-diindolylmethane (DIM) as a potent microRNA-21 antagonist. However, data on DIM and microRNA-21 interplay is controversial, which may be caused by the limitations of the cell lines.

In this study, we established a tumor organoid culture from metastatic breast cancer and tested the efficiency of DIM in combination with common chemotherapeutic drugs used in clinic. Organoids shared morphologic features with the primary tumor, captured tumor heterogeneity, and possessed unique genetic characteristics. Here, we report that DIM suppresses mir-21-5p expression and enhances susceptibility of patient-derived breast cancer organoid to cyclophosphamide and methotrexate treatment. Our data support the hypothesis that small molecules can be utilized as microRNA silencers to overcome cancer-related drug resistance and other pathologies.

Abstract reasoning is associated with the ability to detect relations among objects, ideas, events. It underlies the understanding of other individuals’ thoughts and intentions. In natural settings, individuals have to infer relevant associations that have proven to be reliable or precise predictors. Salience theory suggests that the attribution of meaning to stimulus depends on their contingency, saliency, and relevance to adaptation. So far, subjective estimates of relevance have mostly been explored in motivation and implicit learning. Mechanisms underlying formation of associations in abstract thinking with regard to their subjective relevance, or salience, are not clear. Applying novel computational methods, we investigated relevance detection in categorization tasks in 17 healthy individuals. Two models of relevance detection were developed: a conventional one with nouns from the same semantic category, an aberrant one based on an insignificant common feature. Control condition introduced non-related words. The participants were to detect either a relevant principle or an insignificant feature to group presented words. In control condition they inferred that the stimuli were irrelevant to any grouping idea. Cross-frequency phase coupling analysis revealed statistically distinct patterns of synchronization representing search and decision in the models of normal and aberrant relevance detection. Significantly distinct frontotemporal functional networks with central and parietal components in the theta and alpha frequency bands may reflect differences in relevance detection.

The simplicity and convenience of collecting saliva, as well as its component composition, make this biological fluid a common object of laboratory research, in particular for detecting the nucleic acids of viruses and bacteria, monitoring certain clinical conditions. The range of clinical situations where to use saliva as a diagnostic tool is becoming increasingly widespread and also includes determination of secretory status. The aim of this paper is to characterize the secretory status of the oral fluid, depending on the presence of group-specific antigens of the AB0 system. Antigens of the AB0 system are commonly considered in the context of immunohematology and transfusiology, however, there are new data about the significance of the research in saliva. These results are interesting not only for practical medicine as a convenient and non-invasive diagnostic method, but also for solving fundamental problems. Determining glycome of patient’s oral fluid as an individual specific parameter will help to create a new personalized approach in preclinical diagnosis and develop preventive measures for many known diseases.

Human genetic variability is thought to account for a substantial fraction of individual biochemical characteristics — in biomedical sense, of individual drug response. However, only a handful of human genetic variants have been linked to medication outcomes. Here, we combine data on drug-protein interactions and human genome sequences to assess the impact of human variation on their binding affinity. Using data from the complexes of FDA-drugs and drug-like compounds, we predict SNPs substantially affecting the protein-ligand binding affinities. We estimate that an average individual carries ~6 SNPs affecting ~5 different FDA-approved drugs from among all of the approved compounds. SNPs affecting drug-protein binding affinity have low frequency in the population indicating that the genetic component for many ADEs may be highly personalized with each individual carrying a unique set of relevant SNPs. The reduction of ADEs, therefore, may primarily rely on the application of computational genome analysis in the clinic rather than the experimental study of common SNPs.

The paper examines the changes in the physician’s motivation at work during the period of reforms the salary system started since 2008. These reforms have included a shift from fixed salary system to pay for performance remuneration as well as sufficient increase of salary. The data of six surveys of health workers implemented in 2007-2016 were used to reveal the hierarchy of physician’s motives at work and to track their changes during the period of time under consideration. The changes were minor, and the directions of these changes were rather opposite to the expected strengthening of financial motivation at work: the importance of the motive of earning money has moved from the first place. The share of doctors willing to work more and better on the condition of linking salary with labor contribution did not increase. In contrast, almost two-thirds of physicians believe that they are working on a high level of quality and performance. The majority of physicians desire to increase not a stimulating part of the salary but a base, fixed one. Doctors who receive bonuses for the intensity, quality and performance, and who have a higher amount of salary wish to see the share of fixed part of salary higher than it is now available. This is a clear indication of orientation of this professional to strengthening the protective function of the salary rather than to use increased opportunities for earning money.

The paper explores primary health care models in Russia and in Central and Eastern European (CEE) countries. Starting with the similar model, they have taken totally different ways of primary health care transformation, including the role of general practitioner, multispecialty polyclinics and private sector. The comparison of this diversity, based on the conceptual framework of Primary Health Care Activity Monitor in Europe, demonstrated that the scores of primary care in Russia are relatively lower, particularly in the dimensions of accessibility, comprehensiveness, continuity and coordination of care. The score of the selected efficiency indicators is also relatively low. The major reasons for this are discussed, including the lack of strategic vision on the role of primary care, an excessive specialization of primary care and the delay with a shift to a general practitioner model. A debatable issue of primary care extended composition (the involvement of a growing number of specialists) is also addressed. The conceptual presumption that an extended composition presents new opportunities for more integrated care and better performance has not been supported by the evidence. Big multispecialty policlinics in Russia don’t demonstrate advantages over solo and group GP practices that dominate in CEE countries. The potential of polyclinics is not used because of the lack of specific activities for integration. It is argued that new specialists in the practices can strengthen primary care only when they support generalists rather than replace them. The lesson learnt from CEE countries is that substantial changes are needed to overcome the lagging status of primary care in Russia, including overcoming the excessive specialization of primary care, the replacement of district physicians by general practitioners, developing the forms of independent practices operating in parallel with polyclinics and competing with them.

Having one of the highest physician-population ratios in the world, Russia – paradoxically – also faces shortages of physicians. This paper explores the reasons for this paradox through examining the structural characteristics of the Russian health workforce and its development. In comparing Russia with mainstream European countries and in particular the ‘new” EU countries we argue that the shortage of physicians is determined mostly by the prevailing model of health workforce development with its enduring emphasis on quantitative rather than structural indicators. First, the traditional perception of physicians as inexpensive health resources determines the long-term growth of their jobs – irrespective of the new opportunities for substitution and other structural innovations. Second, there is a persistent distortion in the composition of physician supply, of which the most important is the very low share and narrow remit of primary health care providers in comparison to European standards. Third, the international trends in the division of labor between physicians, medical nurses and allied health personnel are not followed in Russia with the result of an inevitable overburden of physicians, the reproduction of a large supply of physicians, while also the paradoxical shortage. Fourth, the system of professional development of physicians does not match international standards. Although with a substantial delay, Russia has now started transition to a workforce model focused on structural characteristics of human resources and so, in the final part of the paper, these new initiatives of the Government are critically assessed.

Background: With the rapid growth of online social network sites (SNS), the issue of health-related online communities and its social and behavioral implications have become increasingly important for public health and healthcare. Unfortunately, online communities often become vehicles for promotion of pernicious misinformation, for example, alleged harm of vaccination or that HIV-virus is a myth (AIDS-denialism). This study seeks to explore the social structure and participants' behavior of the AIDS-denialists online community to identify and estimate the those who potentially are most susceptible to AIDS-denialists arguments  - “the risk group” in terms of becoming AIDS-denialists. Methods: Social network analysis was used for examining the most numerous AIDS-denialist community in the most popular Russian SNA “VKontakte”, which numbered 13000 – 15 000 members during the various stage of analysis. Qualitative content analysis was also used for collecting relevant for this study members’ attributes, such as HIV status and the extent of belief in AIDS-denialists arguments. Two datasets were collected to analyze friendship  relations between community members and their communication relations. Results: Using social network analysis combined with content-analysis we have identified the core of online community - cohesive and dedicated AIDS-denialists, and the risk group, which is not equal in composition to all peripheral members appeared in the online group. The risk group is the circle of users who engage with core members through online communication and may be more susceptible the AIDS-denialist propaganda. Analysis allowed to significantly reduce the target audience for possible intervention campaign and simultaneously increase the accuracy of user selection into the risk group (1369 users from the risk group is more than 10 times less than whole online group population counting over 15,000 users). Thus, online information interventions should be aimed at this risk group audience in the first place to prevent their adoption of AIDS-denialism beliefs, further spread of AIDS-denialism, and pernicious health consequences associated with being an HIV-positive AIDS-denialist. Conclusion: More research on influence of AIDS-denialism on HIV-positive online group members is needed. Of particular interest are longitudinal or case control studies that could detect the size of effect of AIDS-denialist propaganda that is communicated from hard-core denialists to the risk group, different factors associated with higher or lower susceptibility to AIDS-denialist views, and real health behavior change that occurs with becoming an AIDS-denialist.

The article is based on the preliminary results of author’s current study of the implementation of electronic health records in one of Russian outpatient clinics. Interviews with doctors, developers, managers of the State Department of Healthcare, IT-specialists, and clinic’s head, as well as observations of doctors’ everyday work, show that one of the key problems in the transition from paper to electronic record-keeping is how new information system transforms (or fails to transform) doctors’ routine, habitual activities. The article suggests that the widespread view of habitual action as an action in accordance with a preliminary scheme — a view that forms a basis for the majority of medical information systems — does not describe the actual structure of healthcare activities. The analysis of how doctors perceive and use electronic health records in their daily practice demonstrates that a situational approach to routine actions is more adequate. For example, the use of so-called “templates” that are created by doctors within the electronic health records cannot be understood without reference to the situational context of professional activities. Doctors, creating and using various “templates,” do this in such ways that allow them to make these health records circumstantially understandable. The view of routine activities as situated, concerted achievements not only proves the possibility of a new approach to the description of habitual actions’ role and place in the structure of social action, but can be important for the design and evaluation of professional information systems.

The article focuses on four major assumptions that underlie the alternative conceptualization of public recreation marketing. It explains (1) the redistribution system within recreation resources are allocated; (2) the organizational structure of recreation agencies; (3) the ways in which public recreation agencies interact with local governments and citizens; and (4) the code of ethics and its influence on the behavior of recreation professionals. Finally, the article attempts to integrate these assumptions into an alternative definition of public recreation marketing that is termed “administered marketing.”

This paper presents a method and computational technology for forecasting ambulance trips. We used statistical information about the number of the trips in 2009-2013, the meteorological archive, and the corresponding archive of the meteorological forecasts for the same period. We take into account social and meteorological predictors simultaneously. The method may be used operatively for planning in the ambulance service. It may be applied for all trips and for specific subgroups of diseases. The method and the technology may be applied for any megalopolis if the corresponding medical and meteorological information is available.

The paper considers the changes in major proximate determinants of fertility in Russia within the framework of demographic transition theory and Bongaarts approach to fertility analysis. After World War II Russian fertility became fully controlled process. The complex interplay of abortion and contraception during the Soviet period resulted in a very high abortion level. Russian government has almost never supported and promoted family planning as alternative to abortion. However couple's preferences of small offspring appeared more powerful than the will of authorities. Current trends show that albeit lack of governmental support the society itself is evolving towards more humanistic and effective birth control. Estimates made upon recent surveys' data confirm the validity of official statistics and thus the reality of favorable trend of abortion decline.
