The thought-provoking paper by Cooper (2021) provides a beacon for researchers across disciplines contributing to the domain of innovation management. identifies five developments originating from need accelerating product development in COVID-19 pandemic, but he also highlights root cause which lies at deeper level change, viz. digital transformation. Digitalization has increasingly reduced cy...
Logging and poor shifting cultivation negatively affect initial soil carbon (C) storage, especially at the initial stage of deforestation, as these practices lead to global warming. As a result, an afforestation program is needed to mitigate this problem. This study assessed initial soil C buildup of rehabilitated forests using Fourier transform infrared (FTIR) spectroscopy. The relatively high...
The road coloring problem is an interesing problem proposed over 40 years ago by Adler, Goodwyn and Weiss. Hundreds of mathematicians worked on this problem and failed to make the conjecture a theorem. Finally, in 2007, it was proved by a 60-year-old Israeli mathematician, Avraham Trahtman. It turns out the prove was quite simple after Trahtman partitioned the graph into cycles and trees. The d...
Abstract We analyze the trade effects of a new unfolding transport infrastructure in connection with China’s Belt and Road Initiative . Using panel data for years 1996–2018, featuring 27 exporting countries 96 industries, we exploit variation timing number railway connections to estimate whether European benefit from increased export revenues product variety their shipments China. find that bot...
The Prevent Alcohol and Risk Related Trauma in Youth (P.A.R.T.Y.) program is an injury prevention program set up in 2011 at a Level-1 trauma center in Germany. Its objective is the prevention of road traffic accidents among young road users. Our goal is to enable adolescents to recognize risks and to improve life-changing behavior to reduce the severity of injury and the number of killed young ...
Against the backdrop of global warming and depletion natural resources, new techniques alternative materials need to be explored integrated into road construction. Reclaimed Asphalt Pavement (RAP) is one waste that can reused in projects if its behavior better understood. Numerous researchers have studied use RAP both bound unbound pavement layers. However, mechanical deformation characteristic...
