Rankings are widely regarded as particularly well-suited for capturing the public eye, which is considered a reason why they have become ubiquitous. However, we know little about how rankings direct media attention, well in turn shape and help sustain careers of specific over longer periods time. To advance our understanding discursive dynamics at intersection press, this study examines career ...

The authors propose a new climatic drought index: the standardized precipitation evapotranspiration index (SPEI). The SPEI is based on precipitation and temperature data, and it has the advantage of combining multiscalar character with the capacity to include the effects of temperature variability on drought assessment. The procedure to calculate the index is detailed and involves a climatic wa...

The well-to-wheels assessment is widely used in the automotive sector to analyze the efficiency and competitiveness of different powertrain/fuel options. The paper proposes a global index that takes into account both the energy and environmental aspects on an uniform basis, through the assignment of the costs associated to the energy and to the pollutant emissions. The European market is analyz...

introduction: burden of hiv and aids is considerably different among regions and countries of the world. the aim of this study was to assess of inequality in the prevalence of hiv, according to human development index among countries of the world.methods: in this study the desired outcome was prevalence of hiv, which estimated in 100 countries in 2012. the annual report of unaids was used for p...

[1] Using nonlinear dynamical techniques, we statistically investigate whether the simulated substorms from global magnetohydrodynamic (MHD) models have a combination of global and multiscale features, revealed in substorm dynamics by Sitnov et al. [2000] and featured the phase transition-like behavior. We simulate seven intervals of total duration of 280 hours from the data set used in the abo...

Lepidoptera (moths and butterflies) form one of the four largest animal orders, with published estimates that around 174,250 species had been described up to 2009 (Chapman 2009). Many are conspicuous, charismatic regularly recorded by citizen scientists. As a result, iNaturalist contains more than 15 million observations (10.5% all observations), Global Biodiversity Information Facility (GBIF) ...

Cognition is comprised of the faculties: perception, creativity, intuition, and ratiocination. Optimal levels of cognition are needed for independent functioning and balanced living. With an aging population that continues to grow, dietary supplements that tilt the balance towards maintenance of cognition are being marketed for vulnerable populations facing these challenges. Randomized clinical...

The Global Solar UV Index was developed as an easyto-understandmeasure of the amount of biologically-effective ambient solar ultraviolet radiation (UVR) at different locations on the earth’s surface. Over the past few years, questions have been raised about the global applicability of the UV Index, about the evidence base for exposure risk thresholds and related protective measures, and about w...
