This paper examines how institutional investors respond to accounting restatements. We show that transient institutional investors, defined as institutions with shorter investment horizons and higher portfolio turnover, significantly reduce their holdings in a restating firm at least one quarter...

Urban air pollution has severe negative effects on health and the economy, especially in developing and industrializing countries, such as China and India. Although the transportation sector is widely acknowledged as among the largest contributors to urban air pollution, quantifying its causal...

This study examines how institutions respond to insider trade in addition to accounting information. I show that transient institutions defined as those with short investment horizon and high turnover, reduce holdings in the following quarters when insiders are net sellers following earnings...

Quantifying the effect of transportation on urban air pollution is challenging because decisions to travel are endogenous to air quality. The spread of COVID-19 offers a unique opportunity for causal identification, as the pandemic directly affects decisions to travel and choices of...

Changes in trading relationships including trade wars can have a large impact on the distribution of GHG emissions across supply chains. While previous studies have examined the emission impacts resulting from tariff adjustments during China-US trade wars they do not investigate what would...

A questionnaire survey was performed in eight Chinese cities (40,279 adults participated; response rate 75%). There were questions on demographic information of the participants, allergic rhinitis, asthma, perceived odors and home environment. Among participants: the majority were women (74.7%)...

The formation mechanisms of ash/deposit from cotton stalk (CS) water-cooled vibrating grate boiler combustion were explored according to the characteristics of ash/deposits. Measurements of the ash fusion characteristics indicate the ash fusion temperature under oxidizing atmosphere (O 2 /CO 2 ,...

We aimed to study if microbial volatile organic compounds in air at home were associated with adult asthma and lung function. Associations between measured microbial volatile organic compounds and 2-ethyl-1-hexanol in dwellings and asthma score (based on 8 questions), lung function were...

Source mobile recording device identification aims to identify the source device through intrinsic audio characteristics, and it has been widely employed in various digital audio forensic scenarios. However, the existing methods have the problem of separating the short-term spatial information...

Digital nucleic acid amplification technologies (dNAATs) have become an emerging platform for pathogen detection. It is not only suitable for the absolute quantitative analysis of target pathogens with very low concentration in samples, but also have strong resistance to complex matrix. Thanks...
