This paper studies the persistent effects of China’s Great Wall, built in the Ming Dynasty (1368-1644), on contemporary regional ethnic diversity and economic development. Using rich township-level and individual-level data combined with spatial regression discontinuity strategy, we find that...

The wastewater treatment performance in an inverted A2/O reactor supplemented with fermentation liquid of primary sludge was explored comparing to commercial carbon sources sodium acetate and glucose. Similar COD removal rate was observed with the effluent COD stably reaching the discharge...

The impacts of sea level rise (SLR) are already being felt in many populous and low-lying coastal areas worldwide, making it one of the most pressing threats posed by climate change. While public concerns and perceptions regarding SLR have been widely studied, there remains limited research...

This paper proposes a new measure of firm digital transformation from the perspective of investment after pointing out the weakness of measures used in previous research. Using the new measure and the panel data of manufacturing listed companies in China during 2009-2020, this paper examines the...

Background Multimorbidity and frailty represent emerging global health burdens that have garnered increased attention from researchers over the past two decades. We conducted a scientometric analysis of the scientific literature on the coexistence of multimorbidity and frailty to assess major...

We construct a corporate workplace equality measure based on textual analysis of equal employment opportunity statements in online job postings of US listed companies. We verify this measure by demonstrating its predictive power of future employment discrimination lawsuits and identifying the...

We examine whether industry-level short interest predicts industry stock returns and find that the former is negatively associated with the latter. Furthermore, this predictive ability is more pronounced in industries with higher information asymmetry surrounding firms, suggesting that either...

When a platform is an optional intermediary, should it require price coherence, i.e., that sellers charge the same price to the platform’s users as they charge their direct customers? If the platform does this, how will it affect consumers’ and overall welfare? In a model leveraging insight...

In the present work, the impact of purge time on the performance of TFTs was systematically investigated because both ZnO channel layers and Al 2 O 3 insulators were deposited using deionized water (H 2 O) as oxidant at low temperature. Compared with the Al 2 O 3 thin films (short purge time),...
