This article assesses the network robustness of technological capability base 269 European metropolitan areas against potential elimination some their capabilities. By doing so, it provides systematic evidence on how conditioned economic resilience these regions in context 2008 crisis. The analysis concerns calls relevant literature for more in-depth link between regional structures and to shocks. adopting a science approach that is novel geographic inquiry, objective stress test by...
This paper examines how gamification affects user intention to use mobile healthcare applications (mHealth) and the effect of works differently according health status, age, gender. We data from a survey conducted by Korean representative agency. estimate on based structural equation model examine moderating effects self-reported find that is effective in increasing mHealth, especially healthy younger groups. These findings suggest with factor, would encourage (but lack exercise) people as...
New hole injection layer (HIL) materials for organic light-emitting diodes (OLEDs) based on phenothiazine and phenoxazine were synthesized, the electro-optical properties of synthesized examined by UV−vis photoluminescence spectroscopy, cyclic voltammetry. 10,10′-bis(4-tert-butylphenyl)-N7,N7′-di(naphthalen-1-yl)-N7,N7′-diphenyl-10H,10′H-3,3′-biphenoxazine-7,7′-diamine (1-PNA-BPBPOX) showed glass transition temperatures (Tg) 161 °C, which was higher than that (110 °C)...
Abstract Regional knowledge spaces are heterogeneous, and the structure of these can play a significant role in shaping regional economic performances during downturns. This article explores relationship between region’s technological profile its resilience to exogenous shocks. To identify determinants resilience, we perform panel analyses EU 15 NUTS II level data covering years before after 2008 financial crisis. The most results that, beyond pure diversification effects, regions endowed...
Tin (Sn) halide perovskites are promising materials for various electronic applications due to their favorable properties. However, facile interaction with atmospheric oxygen (O2) often hinders the practical use of Sn-based perovskites, which is regarded as a major cause undesired variations in electrical and structural Herein, we report reversible p-doping phenethylammonium tin iodide ((PEA)2SnI4) transistors when they exposed sequentially ambient vacuum conditions. Exposure conditions...
As the over-the-top (OTT) service market continues to evolve, with new large global players entering already crowded market, competition between various OTT services for subscribers has intensified. In this study, we aim investigate impact of user preference content on selection specific by consumers. Specifically, employ conjoint experiment (CE) method examine consumer utility, relative importance, and marginal willingness pay (MWTP) subscription attributes. Especially, presence users’...
In a system of charged chiral fermions driven out equilibrium, an electric current parallel to the magnetic field can generate dynamic instability by which electromagnetic waves become amplified. Whether similar occur in solid-state systems remains open question. Using time-domain terahertz (THz) emission spectroscopy, we detect signatures what dub ``dynamic magneto-chiral instability" elemental tellurium, structurally crystal. Upon transient photoexcitation moderate external field,...
Over-the-top (OTT) firms must overcome the hurdle of competitive Korean media market to achieve sustainable growth. To do so, understating how users enjoy OTT and analyzing usage patterns is essential. This research aims empirically identify a profitable niche in by applying segmentation theory. In addition, it investigates an effective content strategy convert free into paying customers belonging segments. The latent class regression model was applied Media Panel Survey data divide...
Knowledge recombination, combining knowledge existing (exploitation) or new capacity (exploration) for creating collaboration, is one of the important ways achieving innovation. However, little has known about how recombination types affect differently to production efficiency at a regional level. This study explores relationship between exploitation and exploration technical by using empirical data sets EPO PATSTAT, Eurostat, Cambridge Econometrics database. For this purpose, three stages...
