Numerous problems of cross-border cooperation in the North Western Russia, in particular in the Leningrad region, are not defined only by features of interstate relations, but also by the problems of development of the border settlements. Cities with border points crossing creates the first impressions of the foreign visitors about Russia and therefore the search for the ways of their transformation and development is actual. In the Leningrad Region there are two border towns - Ivangorod (border with Estonia) and Svetogorsk (they border with Finland). Despite the differences in the border location of these towns relative to state borders, the problems of them are very similar. At present, both Ivangorod and Svetogorsk are not in the best position, and for these border towns most of the problems of small towns of Russia are characteristic. This is a range of territorial, transport, functional planning, economic and recreational problems.

African swine fever (ASF) was introduced into the Eastern European Union in 2014 and led to considerable mortality among wild boar. In contrast, unexpected high antibody prevalence was reported in hunted wild boar in north-eastern Estonia. One of the causative virus strains was recently characterized. While it still showed rather high virulence in the majority of experimentally infected animals, one animal survived and recovered completely. Here, we report on the follow-up characterization of the isolate obtained from the survivor in the acute phase of infection. As a first step, three in vivo experiments were performed with different types of pigs: twelve minipigs (trial A), five domestic pigs (trial B), and five wild boar (trial C) were inoculated. 75% of the minipigs and all domestic pigs recovered after an acute course of disease. However, all wild boar succumbed to infection within 17 days. Representative samples were sequenced using NGS-technologies, and whole-genomes were compared to ASFV “Georgia 2007/1”. The alignments indicated a deletion of 14560 base pairs at the 5’ end, and genome reorganization by duplication. The characteristic deletion was confirmed in all trial samples and local field samples. In conclusion, an ASFV variant was found in Estonia that showed reduced virulence.

This article presents a meta‐analysis of recent microeconometric evaluations of active labour market policies. We categorise 199 programme impacts from 97 studies conducted between 1995 and 2007. Job search assistance programmes yield relatively favourable programme impacts, whereas public sector employment programmes are less effective. Training programmes are associated with positive medium‐term impacts, although in the short term they often appear ineffective. We also find that the outcome variable used to measure programme impact matters, but neither the publication status of a study nor the use of a randomised design is related to the sign or significance of the programme estimate.

Nucleotide-binding leucine-rich repeat (NB-LRR, or NLR) receptors mediate pathogen recognition. The Arabidopsis thaliana NLR RPP1 recognizes the tandem WY-domain effector ATR1 from the oomycete Hyaloperonospora arabidopsidis through direct association with C-terminal LRRs. We isolated and characterized homologous NLR genes RPP1-EstA and RPP1-ZdrA from two Arabidopsis ecotypes, Estland (Est-1) and Zdarec (Zdr-1), responsible for recognizing a novel spectrum of ATR1 alleles. RPP1-EstA and -ZdrA encode nearly identical NLRs that are phylogenetically distinct from known immunity-activating RPP1 homologs and possess greatly expanded LRR domains. Site-directed mutagenesis and truncation analysis of ATR1 suggests that these homologs recognize a novel surface of the 2nd WY domain of ATR1, partially specified by a C-terminal region of the LRR domain. Synteny comparison with RPP1 loci involved in hybrid incompatibility suggests that these functions evolved independently. Closely related RPP1 homologs have diversified their recognition spectra through LRR expansion and sequence variation, allowing them to detect multiple surfaces of the same pathogen effector. Engineering NLR receptor specificity may require a similar combination of repeat expansion and tailored amino acid variation.

It is widely believed that countries with greater levels of income inequality also have lower levels of intergenerational mobility. This relationship, known as the Great Gatsby Curve (GGC), has been prominently cited by high-ranking public policymakers, bestselling authors, and Nobel Prize–winning academics. Yet, relatively little crossnational work has empirically examined the mechanisms thought to underpin the GGC—particularly with regard to the role of educational attainment. This paper uses the cross-nationally comparable Programme for International Assessment of Adult Competencies (PIAAC) data set to shed new light on this issue. We find that income inequality is associated with several key components of the intergenerational transmission process—including access to higher education, the financial returns on education, and the residual effect of parental education upon labor-market earnings. Thus, consistent with theoretical models, we find that educational attainment is an important driver of the relationship between intergenerational mobility and income inequality. We hence conclude that unequal access to financial resources plays a central role in the intergenerational transmission of advantage.

African swine fever (ASF) is a severe viral disease that is currently spreading among domestic pigs and wild boar ( Sus scrofa ) in large areas of Eurasia. Wild boar play a key role in the spread of ASF, yet despite their significance, little is known about the key mechanisms that drive infection transmission and disease persistence. A mathematical model of the wild boar ASF system is developed that captures the observed drop in population density, the peak in infected density and the persistence of the virus observed in ASF outbreaks. The model results provide insight into the key processes that drive the ASF dynamics and show that environmental transmission is a key mechanism determining the severity of an infectious outbreak and that direct frequency dependent transmission and transmission from individuals that survive initial ASF infection but eventually succumb to the disease are key for the long-term persistence of the virus. By considering scenarios representative of Estonia and Spain we show that faster degradation of carcasses in Spain, due to elevated temperature and abundant obligate scavengers, may reduce the severity of the infectious outbreak. Our results also suggest that the higher underlying host density and longer breeding season associated with supplementary feeding leads to a more pronounced epidemic outbreak and persistence of the disease in the long-term. The model is used to assess disease control measures and suggests that a combination of culling and infected carcass removal is the most effective method to eradicate the virus without also eradicating the host population, and that early implementation of these control measures will reduce infection levels whilst maintaining a higher host population density and in some situations prevent ASF from establishing in a population.

BACKGROUND : This study further develops Goldstein et al.'s (2013) analysis of the fertility response to the Great Recession in western economies. OBJECTIVE : The purpose of this paper is to shed light on the fertility reaction to different indicators of the crisis. Beyond the structural labor market conditions, I investigate the dependence of fertility rates on economic policy uncertainty, government financial risk, and consumer confidence. METHODS : Following Goldstein et al. (2013), I use log-log models to assess the elasticity of age-, parity-, and education-specific fertility rates to an array of indicators. Besides the inclusion of a wider set of explanatory variables, I include more recent data (2000-2013) and I enlarge the sample to 31 European countries plus the United States. RESULTS : Fertility response to unemployment in some age-and parity-specific groups has been, in more recent years, larger than estimated by Goldstein et al. (2013). Female unemployment has also been significantly reducing fertility rates. Among uncertainty measures, the drop in consumer confidence is strongly related to fertility decline and in Southern European countries the fertility response to sovereign debt risk is comparable to that of unemployment. Economic policy uncertainty is negatively related to TFR even when controlling for unemployment. CONCLUSIONS : Theoretical and empirical investigation is needed to develop more tailored measures of economic and financial insecurity and their impact on birth rates. CONTRIBUTION : The study shows the nonnegligible influence of economic and financial uncertainty on birth rates during the Great Recession in Western economies, over and above that of structural labor market conditions.

Occupational mismatch has been a hot topic in the economics literature in recent decades; however, no consensus has been reached on how to conceptualise and measure this phenomenon. We explore the unique opportunity offered by the PIAAC survey to measure occupational mismatch at the individual level based on both education- (overeducation) and skill-based (overskilling) variables by using both objective and subjective measures. For this purpose, we use data on 17 European countries and compute up to 20 different indicators of occupational mismatch. We find that the conceptualisation and measurement of occupational mismatch are indeed important and that education and skill mismatch do not measure the same phenomenon. In fact, only a small percentage of mismatched individuals are mismatched with respect to both education and skill, whereas the majority are mismatched with respect to either education or skill only. At the country level, we find a negative correlation between the incidence of education and skill mismatch, which has important implications for policies aiming to address this labour market inefficiency.

African swine fever (ASF) in wild boar populations is difficult to control. In affected areas, samples from all wild boar shot and found dead are investigated. The use of laboratory tests allows estimating the duration of the infection in affected animals. The study aimed to test the hypothesis that the stage of the epidemic in different areas of Estonia can be assessed on the basis of prevalence estimates. ASF surveillance data of Estonian wild boar were used to estimate prevalences and compare them between the East and West of Estonia. The temporal trend of the estimated prevalence of ASF virus positive animals and of the estimated seroprevalence of wild boar showing antibodies against ASFV was analyzed. Due to the potential influence of population density on the course of ASF in wild boar, also population density data (number of wild boar/km 2 ) were used to investigate the relationship with laboratory test results. In areas, where the epidemic had already lasted for a long time, a small number of new cases emerged recently. The prevalence of samples that were only seropositive was significantly higher in these regions as compared to areas, where the epidemic is in full progress. The observed course of the disease could be the beginning of an ASF endemicity in this region. However, the results may also indicate that ASF has started to subside in the areas that were first affected in Estonia.

Over the past decade, digitalisation has gained significant attention across various European Union (EU) policy areas, particularly in the energy sector. Along with this, digitalisation can contribute to higher energy security and sustainability of the EU energy systems especially by reducing fossil fuel dependency and distributing energy production through micro-renewable generation. However, digitalisation of electricity markets still deals with regulatory hurdles, especially within data management issues, and potential monopolies. Thus, this paper aims to address these challenges within Estonian market and focusing on prosumers' contributions to stabilising the digital electricity market through power generation or demand response. Applying document analysis of legal provisions and the multi-level perspective model of transition, the results indicate that while smart meters are pivotal in demand response and surplus electricity exchange, the current regulations create a de facto monopoly favouring Estonian suppliers, undermining prosumers' interests. Additionally, the concentration of data within a few aggregators can impede competition, while the lack of legal obligations for detailed data access hinders consumers' ability to engage in intra-day and balancing markets. The study highlights the need for legal provisions to facilitate data exchange and access for aggregators while addressing privacy concerns, thereby ensuring competition thrives. It also recommends establishing obligations for timely sharing of individual consumer consumption data and defining 'accounting points' to align with EU regulations. Additionally, clear definitions and provisions for data management, competition law compliance, and consumer rights are crucial. By implementing these recommendations, Estonia can enhance its role as a leader in digitalisation within the EU, promoting a more resilient and sustainable energy system.
