West Nile virus in Spain: Forecasting the geographical distribution of risky areas with an ecological niche modelling approach.
2021
West Nile virus (WNV), a well-known emerging vector-borne arbovirus with a zoonotic life cycle, represents a threat to both public and animal health. Transmitted by ornithophilic mosquitoes, its transmission is difficult to predict and even more difficult to prevent. The massive and unprecedented number of human cases and equid outbreaks in Spain during 2020 interpellates for new approaches. For the first time, we present an integrate analysis from a niche perspective to provide an insight to the situation of West Nile disease (WND) in Spain. Our modelling approach benefits from the combined use of global occurrence records of outbreaks of WND in equids and of its two alleged main vectors i…
Evaluation of the “Bottleneck” Effect in an Isolated Population of Microtus hartingi (Rodentia, Arvicolinae) from the Eastern Rhodopes (Bulgaria) by …
2022
An integrative analysis of an isolated population of Harting’s vole (Microtus hartingi) from the Eastern Rhodope Mountains (Bulgaria) was carried out by morphological and morphometric methods, computed tomography, Cytb variation data, and experimental hybridization. Substantial changes in the development of the skull and teeth were found. Nevertheless, those voles can live to the senex stage. A phylogenetic reconstruction based on Cytb sequences showed that M. hartingi from the Eastern Rhodopes forms a separate clade, which is a sister clade to the voles from Northeastern Greece (also from the foothills of the Rhodopes). M. hartingi from the Rhodopes is mostly isolated reproductively …
Consequences of plant population size and density for plant-pollinator interactions and plant performance
2001
Summary 1 Habitat fragmentation and the resulting decline in the local abundance of plant species can affect biological interactions. We examined the effects of abundance on plant–pollinator interactions by observing the pollinator service and subsequent reproductive output of a mostly outbreeding, but self-compatible, plant, Lychnis viscaria, in experimental populations of different sizes (number of individuals) and densities (distance between individuals). 2 Bumblebees, the main pollinators of L. viscaria, preferred larger populations, but visitation rates were higher in sparser populations. Pollinators were attracted to the larger inflorescences in sparse populations, which were also m…
An ethical algorithm for rationing life sustaining treatment during the COVID-19 pandemic
2020
The burning ethical question raised by the COVID-19 pandemic is how to deal fairly and ethically with a large number of patients simultaneously becoming critically unwell. Across the world, in both developed and developing countries, health systems are grappling with the possibility or the reality that the demand for intensive medical care will outstrip availability. There is a need for ethical guidelines on how to allocate treatment, but such guidelines are potentially highly controversial.1 In this commentary, we set out a simple algorithm (Figure 1), including what we take to be the essential ethical principles that ought to guide resource allocation in any country or setting as well as …

Metropolitan wastewater analysis for COVID-19 epidemiological surveillance
2020
The COVID-19 disease, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a rapidly emerging pandemic which has enforced extreme containment measures worldwide. In the absence of a vaccine or efficient treatment, cost-effective epidemiological surveillance strategies are urgently needed. Here, we have used RT-qPCR for SARS-CoV-2 detection in a series of longitudinal metropolitan wastewaters samples collected from February to April 2020, during the earliest stages of the epidemic in the Region of Valencia, Spain. We were able to consistently detect SARS-CoV-2 RNA in samples taken in late February, when communicated cases in that region were only incipient. We also find…
Outsourcing within the Nordic context: Care services for older people in Finland.
2018
The early 1990s economic setback brought significant reforms favoring the outsourcing of care in Finnish municipalities. Here, outsourcing refers to the practice of municipalities employing private organizations through different means (e.g., open tendering) to deliver public care services. In this context, this study examines the growth in the outsourcing of service housing and home-help services in 311 municipalities from 2001 to 2015 and investigates the municipal factors associated with outsourcing using four dimensions: care needs, population size, economic situation, and political ideology of the municipality. The findings reveal a steep increase in the outsourcing of home-help and se…
Development, Current Situation and Future Prospects of the Private Sport Sector in Europe
2017
This book outlined the private sport sector of the 18 European countries by using the Statistical classification of economic activities in the European Community (NACE Rev. 2, 2008) as a basic statistical framework. According on the country chapters European sport is divided into public, voluntary and private sectors. Depending on how strongly and through what kind of historical processes these sectors have developed, European countries taking part in this project can be classified as 1) historically and traditionally strong non-profit voluntary sport sector countries, 2) former Eastern Bloc countries and 3) countries with strong commercial sport activities. Based on the statistics, sport g…
The Rise in Inequality after Pandemics: Can Fiscal Support Play a Mitigating Role?
2021
Abstract Major epidemics of the last two decades (SARS, H1N1, MERS, Ebola, and Zika) have been followed by increases in inequality [Furceri et al. (2020), COVID Economics, 12, 138–157]. In this article, we show that the extent of fiscal consolidation in the years following the onset of these pandemics has played an important role in determining the extent of the increase in inequality. Episodes marked by extreme austerity—measured using either the government’s fiscal balance, health expenditures, or redistribution—have been associated with an increase in the Gini measure of inequality three times as large as in episodes where fiscal policy has been more supportive. We survey the evidence th…
