This paper investigates the effect of CFO gender on corporate financial reporting decision-making. Focusing firms that experience changes from male to female, compares firms' degree accounting conservatism between pre- and post-transition periods. We find female CFOs are more conservative in their reporting. In addition, we relation varies with levels various firm risks such as litigation risk, default systematic specific risk job security risk. further risk-aversion is associated less...
Directors from academia served on the boards of around 40% S&P 1,500 firms over 1998-2011 period. This paper investigates effects academic directors corporate governance and firm performance. We find that companies with are associated higher performance this relation is driven by professors without administrative jobs. also play an important role through their advising monitoring functions. Specifically, our results show presence acquisition performance, number patents citations, stock price...
This study delves into the unexplored distribution and accumulation of chlorinated paraffins (CPs), pervasive industrial contaminants used as flame retardants plasticizers, within hadal trenches, some Earth's most isolated marine ecosystems. Analysis sediments from Mussau (MS) Mariana trench (MT) reveals notably high total CP concentrations (∑SCCPs + ∑MCCPs) 10,963 14,554 ng g–1 dw, respectively, surpassing those in a reference site western Pacific abyssal plain (8533 dw). In contrast, New...
In the Yellow River Delta, soil salinization and river sediment are two factors influence on economic growth. A large area of reduces crop yields dredged increases management costs. This study evaluated effects applying sediments under different levels irrigation salinity leaching for improving field productivity. three-year experiment (from June 2017 to 2020) was conducted by considering three application:a control (no added, S1), 30▒mm ha−1 (S2) 60▒mm (S3), water: 290▒mm (90▒mm maize +...
Tunas are among the most economically important fish species and play critical roles in food composition nutrition of humans. As apex predators, they also keep marine ecosystem healthy balanced. Both natural human factors influence status this resource their habitats. There is a large cadre studies on how tunas great significance to exploitation management fisheries, yet there few summaries research. We aimed quantitatively qualitatively synthesize global knowledge structure emerging trends...
Squid is traded globally as an important food resource. However, the occurrence of carcinogenic halogenated polycyclic aromatic hydrocarbons (HPAHs) in squid and risk their transfer through trade little understood or recognized. Here, we comprehensively evaluated by quantifying congener-specific concentrations HPAHs 121 samples collected from Pacific, Atlantic Indian oceans. This was first time that nine 36 target chlorinated brominated PAH congeners had been detected squid. The exhibited...
Polycyclic aromatic hydrocarbons (PAHs) and their halogenated derivatives (X-PAHs), which generally produced from photochemical thermal reactions of parent PAHs, widely exist in the environment. They are semi-volatile organic chemicals (SVOCs) partitioning between gas/particulate phases affects environmental migration, transformation fate, further impacts toxicity health risk to human. However, there is a large data missing experimental distribution ratio atmospheric particulate phase (f),...

In order to achieve high precision from non-contact temperature measurement, the hardware structure of a broadband correlative microwave radiometer, calibration algorithm, and inversion algorithm are innovatively designed in this paper. The radiometer is much more sensitive than full power but its accuracy challenging improve due relatively large phase error. study, an error correction designed, which reduces 69.08° 4.02°. Based on integral measuring system with known radiation source,...

The abundance and seasonal change of large-sized tintinnids were studied in Laizhou Bay. Large-sized collected by vertical towing using a shallow sea type III plankton net (open area 0.1 m, mesh size 76 μm) during 9 cruises between May November 2011 from March to April, 2012. samples fixed formalin solution final concentration 5% counted an inverted microscope the laboratory. We sampled 8 stations avoid fluctuations over short time period. purpose this study was characterize tintinnid...
This paper investigates the impact of market for corporate control on firm-level organization capital. We use enactment antitakeover laws as an exogenous decrease in disciplinary effect control. Our results show that capital decreases after laws. These are verified through various endogeneity and robustness tests. find is more pronounced compared to other forms intangible Also, stronger governance competition mitigate decline contributed firm value Moreover, we reductions inflow inventors,...
Abstract In order to achieve accurate verification of the implementation power grid infrastructure investment plan, support dynamic monitoring and risk assessment annual plan implementation. Based on “three rates in one” Investment completion collection value 110 kV above projects, this paper constructs a model for projects. Evaluate rationality current reported progress, predict quantify amount timely discover promote resolution problems, improve lean management level enterprises.
Practical teaching is an important part of personnel training in Colleges and Universities. It plays role improving the quality training, so practical construction must be strengthened. Taking undergraduate hydrology water resources as example, this paper puts forward that system can composed course assignment, practice, social scientific research cases engineering practice ability training. The typical case method emphatically analyzed, independent projects proposed to improve students’...
