The Impact

The paper is a contribution to the empirics of cross-country and cross-region literature on growth economics. Its aim is to assess the role of the global component in the development of European regions during the period 2000–2005. For this purpose a simple leader-follower model is set up in which all countries imitate the technology of the leader. The model is applied to cross-country data of the period 1870–2003 as corroboration and to the cross-region data. This approach makes it possible to rank the regions based on the rate of return of broadly understood capital and the impact of global forces as compared to local ones. Finally, a conclusion is drawn on the extent of the role of imitations in the growth of European regions.

Using cross-country data from 140 countries, this empirical study extends past research by examining the impact of trust on the level of e-government. The major empirical finding of this research shows that, after controlling for the level of economic development and other socio-economic factors, trust as measured by ethnic and religious diversity, is a significant factor affecting e-government usage.

The Impact

In an era of energy transition involving an increase in renewable energy and a reduction in coal-fired power generation and nuclear power generation, the role of combined heat and power (CHP) as a bridging energy is highly emphasized. This article attempts to look empirically into the impact of increasing the share of renewable energy in total electricity generation on CHP share in total electricity generation in a cross-country context. Data from 35 countries during the period 2009–2015 were used, and the least absolute deviations estimator was applied to obtain a more robust parameter estimate. The results showed that a 1%p increase in the share of renewable energy significantly increased the CHP share by 0.87%p. Therefore, the hypothesis that CHP serves as bridge energy in the process of energy transition was established.

The Impact

European countries report large differences in coronavirus disease (COVID-19) case fatality risk (CFR). CFR estimates depend on demographic characteristics of the cases, time lags between reporting of infections and deaths and infrastructural characteristics, such as healthcare and surveillance capacities. We discuss the impact of these factors on the CFR estimates for Germany, Italy, France, and Spain for the COVID-19 pandemic from early March to mid-April, 2020. We found that, first, a large proportion of the difference in CFRs can be attributed to different age structures of the cases. Second, lags of 5-10 days between day of case report and death should be used, since these provide the most constant estimates. Third, for France, Italy, and Spain, intensive care beds occupied by COVID-19 patients were positively associated with fatality risks of hospitalized cases. Our results highlight that cross-country comparisons of crude CFR estimates can be misleading and should be avoided.

Sugar Exports

This paper reviews the major changes and trends in the raw and white sugar trade flows involving Latin American exporters and their partners. The paper assesses the recent absolute and relative growth in the volume of sugar exports from Brazil (the region’s and the world’s dominant exporter) and other major regional exporters such as Guatemala, Cuba, Colombia, Mexico and Argentina. Latin America has emerged as the world’s largest net sugar exporting region. Significant volumes of raw sugar of Latin American origin are now used by a large number of new destination refineries which have been set up in the Middle East and Asia. Indeed, the share of Latin America in global raw sugar exports has increased from 62.8% on average between 2002 and 2004 to 67.3% on average between 2006 and 2008. This paper also evaluates the impact of preferential trade agreements, including the CAFTA and the EPA, for Central American and Caribbean sugar exporters, as well as the implications of NAFTA for Mexico’s sugar. Finally, the paper discusses the potential gains and benefits that diversification into ethanol and cogeneration have provided to the major Latin American sugarcane industries.

The Impact

A hospital was one of the first European institutions set up in Australia in 1788. The aim in this article is to summarise the ensuring events, and particularly to demonstrate how hospitals have dramatically changed. One theme is to clarify the nature of convict hospitals and the low level of care expected in charity hospitals during the nineteenth and early twentieth centuries. Other themes are the impact of medical innovations, and the strong and increasingly interventionist role of the state in hospital governance. More recently, a theme has been the closure of small hospitals and the development of large hospital complexes. Throughout, the role of nurses has been crucial as they have provided the bulk of hospital care. Hospitals have always been plagued by scandals but the striking feature throughout their history in Sydney is the strength of the demand for hospital care.

The Impact

The increasing evidence of fetal developmental effects on postnatal life, the still unknown fetal growth mechanisms impairing offspring generated by somatic nuclear transfer techniques, and the impact on stillbirth and dystocia in conventional reproduction have generated increasing attention toward mammalian fetal growth. We identified a highly significant quantitative trait locus (QTL) affecting fetal growth on bovine chromosome 6 in a specific resource population, which was set up by consistent use of embryo transfer and foster mothers and, thus, enabled dissection of fetal-specific genetic components of fetal growth. Merging our data with results from other cattle populations differing in historical and geographical origin and with comparative data from human whole-genome association mapping suggests that a nonsynonymous polymorphism in the non-SMC condensin I complex, subunit G (NCAPG) gene, NCAPG c.1326T>G, is the potential cause of the identified QTL resulting in divergent bovine fetal growth. NCAPG gene expression data in fetal placentomes with different NCAPG c.1326T>G genotypes, which are in line with recent results about differential NCAPG expression in placentomes from studies on assisted reproduction techniques, indicate that the NCAPG locus may give valuable information on the specific mechanisms regulating fetal growth in mammals.

The Impact

The evaluation of the impact force on structures due to a flood wave is of utmost importance for estimating physical damage and designing adequate countermeasures. The present study investigates, using 2D shallow-water approximation, the morphodynamics and forces caused by a dam-break wave against a rigid obstacle in the presence of an erodible bed. A widely used coupled equilibrium model, based on the two-dimensional Saint–Venant hydrodynamic equations combined with the sediment continuity Exner equation (SVEM), is compared with a more complex two-phase model (TPM). Considering an experimental set-up presented in the literature with a single rigid obstacle in a channel, two series of tests were performed, assuming sand or light sediments on the bottom. The former test is representative of a typical laboratory experiment, and the latter may be scaled up to a field case. For each test, two different particle diameters were considered. Independently from the particle size, it was found that in the sand tests, SVEM performs similarly to TPM. In the case of light sediment, larger differences are observed, and the SVEM predicts a higher force of about 26% for both considered diameters. The analysis of the flow fields and the morphodynamics shows these differences can be essentially ascribed to the role of inertia of the solid particles.

Over Time

AbstractThis paper investigates the role of large outbreaks on the persistence of Covid-19 over time. Using data from 650 European regions in 14 countries, I first show that winter school holidays in late February/early March 2020 (weeks 8, 9 and 10) led to large regional outbreaks of Covid-19 in the spring with the spread being 60% and up-to over 90% higher compared to regions with earlier school holidays. While the impact of these initial large outbreaks fades away over the summer months, it systematically reappears from the fall as regions with school holidays in weeks 8, 9 and 10 had 30–70% higher spread. This suggests that following a large outbreak, there is a strong element of underlying (latent) regional persistence of Covid-19. The strong degree of persistence highlights the long-term benefits of effective (initial) containment policies, as once a large outbreak has occurred, Covid-19 persists. This result emphasizes the need for vaccinations against Covid-19 in regions that have recently experienced large outbreaks but are well below herd-immunity, to avoid a new surge of cases.
