Geographical and temporal distribution of SARS-CoV-2 clades in the WHO European Region, January to June 2020

We show the distribution of SARS-CoV-2 genetic clades over time and between countries and outline potential genomic surveillance objectives. We applied three available genomic nomenclature systems for SARS-CoV-2 to all sequence data from the WHO European Region available during the COVID-19 pandemic until 10 July 2020. We highlight the importance of real-time sequencing and data dissemination in a pandemic situation. We provide a comparison of the nomenclatures and lay a foundation for future European genomic surveillance of SARS-CoV-2.Peer reviewe

UBVRI Light curves of 44 Type Ia supernovae

We present UBVRI photometry of 44 Type la supernovae (SNe la) observed from 1997 to 2001 as part of a continuing monitoring campaign at the Fred Lawrence Whipple Observatory of the Harvard-Smithsonian Center for Astrophysics. The data set comprises 2190 observations and is the largest homogeneously observed and reduced sample of SNe la to date, nearly doubling the number of well-observed, nearby SNe la with published multicolor CCD light curves. The large sample of [U-band photometry is a unique addition, with important connections to SNe la observed at high redshift. The decline rate of SN la U-band light curves correlates well with the decline rate in other bands, as does the U - B color at maximum light. However, the U-band peak magnitudes show an increased dispersion relative to other bands even after accounting for extinction and decline rate, amounting to an additional ∼40% intrinsic scatter compared to the B band

Information Use And New Product Outcomes: The Contingent Role Of Strategy Type

Information is an important resource for firms to develop new products successfully, and firms must rely on their ability to use information effectively. This research builds on information processing and contingency theories to explore the effect of firm strategy type and the conceptual and instrumental use of information on new product outcomes. Firms operating in high-tech industries are faced with high levels of uncertainty caused by rapidly evolving technologies. Consequently, creating innovative and successful products becomes particularly challenging. Past research examining organizational use of information points to the presence of strategic contingencies that may impact the new product outcomes that accrue to a firm. A cross-sectional study was conducted to examine how the impact of information use on new product outcomes varies by strategy type. Using data from 150 software development firms based in a developing economy, the theoretical hypotheses proposed are tested. After controlling for environmental turbulence, the research results demonstrate that firms focusing on specific types of information use innovate successfully only when that information use is congruent with an appropriate strategic orientation. Specifically, the present study finds that prospector firms focusing on conceptual information use enhance both their new product performance and new product creativity outcomes, whereas analyzer firms enhance only their new product performance outcomes. A focus on instrumental information use has different effects for firms. Defender firms enhance both their new product performance and creativity outcomes only when focusing on instrumental information use. In contrast, prospector firms detract from their new product creativity outcomes, and analyzer firms reduce their new product performance outcomes when focusing on instrumental information use
