Based on the institutional theory, this article attempts to examine two consecutive questions regarding the impact of various factors on corporate decision in environmental information disclosure (EID): (1) whether or not to disclose; and (2) the level of disclosure. The relevance of these factors is empirically tested using data collected from publicly listed manufacturing companies from 2006 to 2008 in China. Some interesting findings appear. We find that firms that are state-owned, those that operate in environmentally sensitive industries, those having more industrial peers engaged in EID, and those with better reputation are more likely to disclose environmental information. When it comes to the content of EID, variables that attempt to capture external institutional pressures exhibit either no or weak explanatory power. Only the variable of organizational image and reputation is demonstrated to have a significant impact on both the act and the content of EID. This study provides a snapshot of the dialogues between constituencies in the organizational field and EID development.

The stock market’s reaction to information disclosure of environmental violation events (EVEs) is investigated multi-dimensionally for Chinese listed companies, including variables such as pollution types, information disclosure sources, information disclosure levels, modernization levels of the region where the company locates, ultimate ownership of the company, and ownership held by the largest shareholder. Using the method of event study, daily abnormal return (AR) and accumulative abnormal return (CAR) are calculated under different event window for examining the extent to which the stock market responds to the EVEs. Furthermore, statistical significance of the difference in stock market reaction is compared between event firms with different characteristics. The relationship between CAR and its impact factors is examined by multivariate analysis. The findings reveal that the average reduction in market value is estimated to be much lower than the estimated changes in market value for similar events in other countries, demonstrating that the negative environmental events of Chinese listed companies currently have weak impact on the stock market

We have empirically examined the relationship between top executives’ turnover and the corporate environmental responsibility by identifying the influence of ten specific turnover reasons resulting in the chairman’s departure and two important types of chairman’s succession. Using a sample of 782 manufacturing listed companies across 3 years in China, we find that the corporate environmental responsibility is negatively associated with the involuntary and negative turnover (i.e., dismissal, health and death, and forced resignation) and positively associated with improving corporate governance, and not associated with the normal turnover (i.e., retirement and contract expiration) and the types of chairman’s succession (i.e., independence, and internal or external promotion). Our study significantly contributes to research in environmental disclosure by revealing the relationship between chairman’s turnover and the corporate environmental responsibility. A feasible way is suggested to regulators and other stakeholders in monitoring or assessing the possible abnormality of environmental responsibility when firms experience involuntary and negative chairman’s turnover in the emerging economies

After more than 40 years of development, China has established a relatively complete system of lawyers, including laws and regulations, a unified qualification examination, and lawyers associations. Today, there are nearly 600,000 lawyers working in various fields. However, the Communist regime in China has never adopted the so-called Western values of freedom and equality, the guarantee of human rights, and the rule of law, while the socialist ideology emphasizes the obedience of the individual to the collective and to the power of the State, and thus the Communist Party has always emphasized management and control in its attitude toward lawyers. At the same time, because of its consistency with socialist ideology in many aspects, various concepts of traditional Chinese law have been preserved, which allowed a prejudice against lawyers based on traditional Chinese legal culture to persist to this day, to the extent that many Chinese people lack trust in lawyers. Chinese lawyers have no choice but to tactfully try to come to terms with the Communist Party and overcome traditional attitudes and unfavorable publicity against lawyers.

However, most current understanding of the electronic structure near band valleys in momentum space is based on either theoretical investigations or optical measurements, leaving the detailed band structure elusive. For example, the exact position of the conduction band valley of bulk MoS2 remains controversial. Here, using angle-resolved photoemission spectroscopy with submicron spatial resolution, we systematically imaged the conduction/valence band structure evolution across representative chalcogenides MoS2, WS2, and WSe2, as well as the thickness dependent electronic structure from bulk to the monolayer limit. These results establish a solid basis to understand the underlying valley physics of these materials, and also provide a link between chalcogenide electronic band structure and their physical properties for potential valleytronics applications.

In addition, many relatively high-performing p-type TCMs require synthesis temperatures >400 °C. Here, room-temperature pulsed laser deposition of copper-alloyed zinc sulfide thin films is reported. For 0.09 ≤ x ≤ 0.35, CuxZn1-xS has high p-type conductivity, up to 42 S cm−1 at x = 0.30, with an optical band gap tunable from ≈3.0–3.3 eV and transparency, averaged over the visible, of 50%–71% for 200–250 nm thick films. In this range, synchrotron X-ray and electron diffraction reveal a nanocrystalline ZnS structure. Secondary crystalline CuyS phases are not observed, and at higher Cu concentrations, x > 0.45, films are amorphous and poorly conducting. Within the TCM regime, the conductivity is temperature independent, indicating degenerate hole conduction. A decrease in lattice parameter with Cu content suggests that the hole conduction is due to substitutional incorporation of Cu onto Zn sites. This hole-conducting phase is embedded in a less conducting amorphous CuyS, which dominates at higher Cu concentrations. The combination of high hole conductivity and optical transparency for the peak conductivity CuxZn1-xS films is among the best reported to date for a room temperature deposited p-type TCM.

To deal with the lack of accuracy and generalization ability in some single models, grain output models were built with lots of relevant data, based on the powerful non-linear reflection of the back-propagation neural network. Three kinds of grain output models were built and took advantage of – particle swarm optimization algorithm, mind evolutionary algorithm, and genetic algorithm – to optimize the BP neural network. By the use of data fusion algorithm, the outcomes of different models can be modified and fused together, and the combination-predicted outcome can be obtained finally. Taking advantage of this combination model to predict the total grain output of China, the results showed that the total grain output in 2015 was a bit larger than the actual value of about 0.0115%. It was much more accurate than the three single models. The experimental results verify the feasibility and validity of the combination model.
