Under Action 14, countries have committed to implement a minimum standard to strengthen the effectiveness and efficiency of the mutual agreement procedure (MAP). The MAP is included in Article 25 of ...the OECD Model Tax Convention and commits countries to endeavour to resolve disputes related to the interpretation and application of tax treaties. The Action 14 Minimum Standard has been translated into specific terms of reference and a methodology for the peer review and monitoring process. The minimum standard is complemented by a set of best practices.The peer review process is conducted in two stages. Stage 1 assesses countries against the terms of reference of the minimum standard according to an agreed schedule of review. Stage 2 focuses on monitoring the follow-up of any recommendations resulting from jurisdictions' stage 1 peer review report. This report reflects the outcome of the stage 1 peer review of the implementation of the Action 14 Minimum Standard by San Marino.

A recent catalog of the ants of Europe and surrounding areas listed no ants recorded from San Marino. One afternoon of collecting in urban sites of San Marino yielded 23 ant species: Aphaenogaster ...subterranea, Camponotus aethiops, Camponotus fallax, Camponotus lateralis, Camponotus piceus, Crematogaster scutellaris, Formica cunicularia, Formica gagates, Hypoponera eduardi, Lasius emarginatus, Lasius lasioides, Lasius paralienus, Messor structor, Pheidole pallidula, Plagiolepis pygmaea, Tapinoma nigerrimum s.l., Temnothorax angustulus, Temnothorax flavicornis, Temnothorax italicus, Temnothorax lichtensteini, Temnothorax tergestinus, Temnothorax unifasciatus, and Tetramorium caespitum. Surprisingly, despite collecting in heavily disturbed urban sites, none of the ants known so far from San Marino are exotic to Europe.
Biomineralization plays a fundamental role in the global silicon cycle. Grasses are known to mobilize significant quantities of Si in the form of silica biominerals and dominate the terrestrial realm ...today, but they have relatively recent origins and only rose to taxonomic and ecological prominence within the Cenozoic Era. This raises questions regarding when and how the biological silica cycle evolved. To address these questions, we examined silica abundances of extant members of early-diverging land plant clades, which show that silica biomineralization is widespread across terrestrial plant linages. Particularly high silica abundances are observed in lycophytes and early-diverging ferns. However, silica biomineralization is rare within later-evolving gymnosperms, implying a complex evolutionary history within the seed plants. Electron microscopy and X-ray spectroscopy show that the most common silica-mineralized tissues include the vascular system, epidermal cells, and stomata, which is consistent with the hypothesis that biomineralization in plants is frequently coupled to transpiration. Furthermore, sequence, phylogenetic, and structural analysis of nodulin 26-like intrinsic proteins from diverse plant genomes points to a plastic and ancient capacity for silica accumulation within terrestrial plants. The integration of these two comparative biology approaches demonstrates that silica biomineralization has been an important process for land plants over the course of their >400 My evolutionary history.
The evolution of the San Marino carbonate succession, developed on a wedge-top basin of the northern Apennines during the Middle Miocene (Torriana outcrop, Marecchia Valley), was studied through a ...high-resolution stable isotope analysis on different carbonate components. A marked positive carbon isotopic excursion is identified at ca. 16 Ma. The excellent correlation of the San Marino δ13C carbonates with the global δ13C reference curve from Zachos et al. (2008) allows to link the marked positive δ13C present in the San Marino section with the global carbon isotope maximum of the Monterey event. Subordinate long-eccentricity-driven δ13C cycles (~405 kyr) as recorded by Holbourn et al. (2007) were also identified. The correlation with carbon signatures of coeval successions of the Mediterranean region shows that this main carbon isotopic excursion at the Burdigalian–Langhian boundary is widely recorded and predates the crisis of these heterozoan shelves. The demise of the San Marino shelf resulted from a combination of global and regional factors that controlled the nutrient budget, the detrital input and the subsidence of the basin. The high-resolution chemostratigraphy of San Marino succession shows that even though the shelf evolved in the complex setting of a wedge-top basin, which should be largely influenced by local factors (i.e. tectonic subsidence and detrital input), it records the Monterey event and its eccentricity paced rhythms with high precision. This highlights the strong connection of the Monterey event with the development and subsequent demise of shallow water carbonate depositional systems in the Mediterranean, irrespective of variable and changing local conditions.
•High-resolution δ13C of carbonate on a wedge-top basin in the interval 16.5–14.5 Ma•The positive δ13C excursion of the Monterey event is registered with high precision.•Subordinate eccentricity-driven δ13C cycles (400 kyr) were also identified.•Primary role of global event over regional influences on the shelf evolution is shown.
Understanding the spatial distribution of coronavirus disease 2019 (COVID-19) cases can provide valuable information to anticipate the world outbreaks and in turn improve public health policies. In ...this study, the cumulative incidence rate (CIR) and cumulative mortality rate (CMR) of all countries affected by the new corona outbreak were calculated at the end of March and April, 2020. Prior to the implementation of hot spot analysis, the spatial autocorrelation results of CIR were obtained. Hot spot analysis and Anselin Local Moran’s
I
indices were then applied to accurately locate high and low-risk clusters of COVID-19 globally. San Marino and Italy revealed the highest CMR by the end of March, though Belgium took the place of Italy as of 30th April. At the end of the research period (by 30th April), the CIR showed obvious spatial clustering. Accordingly, southern, northern and western Europe were detected in the high-high clusters demonstrating an increased risk of COVID-19 in these regions and also the surrounding areas. Countries of northern Africa exhibited a clustering of hot spots, with a confidence level above 95%, even though these areas assigned low CIR values. The hot spots accounted for nearly 70% of CIR. Furthermore, analysis of clusters and outliers demonstrated that these countries are situated in the low-high outlier pattern. Most of the surveyed countries that exhibited clustering of high values (hot spot) with a confidence level of 99% (by 31st March) and 95% (by 30th April) were dedicated higher CIR values. In conclusion, hot spot analysis coupled with Anselin local Moran’s
I
provides a scrupulous and objective approach to determine the locations of statistically significant clusters of COVID-19 cases shedding light on the high-risk districts.
Epidemiological studies on multiple sclerosis (MS) carried out in Southern Europe in the last years have shown a significant increase in the disease frequency. Previous surveys conducted in the ...Republic of San Marino, Northern Italian peninsula, identified that the population is at high risk for MS, with a prevalence of 51.6 per 100,000 population in 1982 and of 166.7 in 2005 and with a mean annual incidence of 7.9 per 100,000 for the period 1990–2005. The present work is a community-based intensive prevalence and incidence survey, by a complete enumeration approach, to update the prevalence and incidence of MS in the Republic of San Marino. The mean annual incidence for the period 2005–14 was 7.7 (95% CI 4.9–11.4) per 100,000, 3.3 (95% CI 1.1–7.6) for men and 11.9 (95% CI 7.2–18.6) for women. On 31 December 2014, 67 patients (19 men and 48 women), suffering from definite or probable MS and living in the Republic of San Marino, yielded a crude prevalence of 204.3 (95% CI 158.4–259.5) per 100,000, 117.8 (95% CI 70.9–183.7) for men and 288.2 (95% CI 212.4–383.3) for women. Our study has confirmed San Marino is an area at high risk for MS, in line with epidemiological data from continental Italy. The marked increase in MS prevalence over time in this population can be ascribable to increased survival and improved ascertainment, in the presence of a substantially stable, yet high, incidence rate.
In August 2020, Sputnik V was registered as Gam-COVID-Vac by the Russian Ministry of Health, and since December 2020 it has been distributed in 61 countries worldwide. On 25 February 2021, the ...Republic of San Marino started its vaccination campaign, which includes Sputnik V. Our aim was to describe the adverse events following immunization (AEFIs) with this vaccine through participant-based active surveillance in the country.
Beginning from 4 March to 8 April 2021, a nationwide study was conducted on San Marino's population aged 18–89 years who received one or two doses of Sputnik V. E-questionnaire dissemination occurred through e-mails, QR-codes or live/phone interviews ~7 days after the first and second vaccine dose. A descriptive analysis was conducted to quantify AEFI incidence on both occasions, stratifying results by type and severity of symptoms.
Mean age of the 2558 vaccine recipients was 66±14 years. First-dose AEFI incidence was 53.3% (systemic reactions at 42.2%), while second-dose AEFI incidence was 66.8% (systemic reactions at 50.4%) (n = 1288). In general, 76.0% of two-dose recipients reported some AEFIs after either vaccine dose, and 2.1% suffered severe reactions; in 60- to 89-year-olds (n = 1021), AEFI incidence was 70.0%, with 53.0% of subjects describing systemic reactions and 0.8% reporting severe symptoms. The most frequent symptoms were local pain, asthenia, headache and joint pain.
Our results, albeit preliminary, suggest that Sputnik V has a high tolerability profile in the population aged ≥60 years in terms of short-term AEFIs.

The article is devoted to the analysis of the cultural policy and diplomacy of the microstates, namely: the Principality of Monaco, the Principality of Liechtenstein, the Principality of Andorra and ...the Republic of San Marino. In the introduction, the author briefly describes the concepts of cultural policy and cultural diplomacy and highlights the problem of insufficiently studied microstates. In the first part of the work, the main institutions that implement the cultural policy of the above states are considered. Further, based on reports provided by countries within the framework of the Compendium, the participation of countries in such international organizations as UNESCO and the Council of Europe is studied. In conclusion, conclusions are drawn that microstates attach particular importance to the development and promotion of their own culture at the international level. For their status, they actively and successfully participate in the activities of specialized international organizations, in the protection and promotion of national languages, in the development of cultural cooperation at the regional level.
Pollen data from three off-site records and twenty-six on-site (archaeological) sites are reviewed to investigate the development of cultural landscapes through the history of the olive, walnut and ...chestnut trees in the Italian peninsula from the Late Glacial to late Holocene. The spread of these trees, which have been gathered or cultivated since ancient times, though not marked by high values in pollen diagrams, is an important indicator of increasing human activity and anthropization in the Mediterranean area.
The sum of Olea, Juglans and Castanea percentages in pollen spectra constitutes the OJC curve. The off-site records discussed are core RF93-30 from the Adriatic Sea (last 7000 years), and cores PALB94-1E of Lago Albano and PNEM94-1B of Lago di Nemi, two lakes in the Latium region (last 13,000 years). The on-site records are located in several regions (Veneto, Emilia Romagna, Tuscany, Basilicata, Calabria, and Sicily) and in the Republic of San Marino. Their chronology spans approximately from the Bronze to the Renaissance ages, from 4200 to 500 BP. The simultaneous presence of OJC in the off-sites and in all the archaeological sites confirms that these trees were widespread in the Italian peninsula during the last four millennia. The OJC pollen sum shows low values but Olea, Castanea and Juglans are common in Bronze age sites from northern Italy, when their percentages increase in the off-site records. In Hellenistic and Roman times, there are sharp increments of their curves in the off-sites, and values of Olea are especially high in archaeological sites of southern Italy. The highest values of OJC, especially due to Castanea, are found in records of the Middle ages. Juglans is significant but less frequent in both the archaeological sites and the off-sites.
The cultivation of walnut and chestnut trees in pre-Roman times may have included local stands. The nurturing for wood may have had negative effects on pollen fallout while the flowering of plants was favoured to obtain fruits.
As humans exploited the natural resources they interfered with the distribution of useful plants. The development of human environments in a modern sense, however, is a relatively recent phenomenon. It has largely caused the expansion of complex agrarian landscapes, including fields, pastures and groves.
