Does investor protection affect the choice of earnings management methods through real activity manipulation and accrual manipulation？ Asian comparison

This paper examines systematic differences in earnings management through real activity manipulation and accrual manipulation across 7 Asia countries. The study proposes arguments that in economies with high investor protection, managers prefer to manage earnings through real activity manipulation rather than through accrual manipulation because accrual manipulation is more likely to draw auditors or regulators scrutiny than real decisions about pricing and production. The study findings are consistent with prediction. Despite being in economies with high investor protection, managers still have bigger discretion in managing earnings through real activities rather than accrual manipulation.

The Effect of Real Activities Manipulation on Accrual Earnings Management： The Case in Indonesia Stock Exchange （IDX）

There are three ways to manage earnings, namely, accruals earnings management, real activities manipulation, and shifting of core expense. The famous methods to manage earnings are accruals earnings management and real activities manipulation. Usually, real activities manipulation is conducted on the going period. The action will increase the loss for the firms at the end of the period. To avoid the loss, managers will manage earnings through accruals （discretionary accruals）. Therefore, the objective of this study is to investigate whether real activities manipulation positively influences accruals earnings management. To investigate the issue, this study collected data from Indonesia Stock Exchange （IDX）. Samples of this study are the manufacturing companies. There are 196 firms from the year 2003 to 2007. The results of this study support the research hypothesis that real activities manipulation positively influences accruals earnings management. The higher the real activities manipulation effects, the higher the accruals earnings management at the end of the period.There are three ways to manage earnings, namely, accruals earnings management, real activities manipulation, and shifting of core expense.

Nonlinear magneto-mechanical-thermo coupling characteristic analysis for transport behaviors of carriers in composite multiferroic piezoelectric semiconductor nanoplates with surface effect

In this paper,to better reveal the surface effect and the screening effect as well as the nonlinear multi-field coupling characteristic of the multifunctional piezoelectric semiconductor(PS)nanodevice,and to further improve its working performance,a magneto-mechanical-thermo coupling theoretical model is theoretically established for the extensional analysis of a three-layered magneto-electro-semiconductor coupling laminated nanoplate with the surface effect.Next,by using the current theoretical model,some numerical analyses and discussion about the surface effect,the corresponding critical thickness of the nanoplate,and the distributions of the physical fields(including the electron concentration perturbation,the electric potential,the electric field,the average electric displacement,the effective polarization charge density,and the total charge density)under different initial state electron concentrations,as well as their active manipulation via some external magnetic field,pre-stress,and temperature stimuli,are performed.Utilizing the nonlinear multi-field coupling effect induced by inevitable external stimuli in the device operating environment,this paper not only provides theoretical support for understanding the size-dependent tuning/controlling of carrier transport as well as its screening effect,but also assists the design of a series of multiferroic PS nanodevices.

Female directors and real activities manipulation:Evidence from China

Unlike previous studies that focus on accrual-based earnings management, this study analyzes real activities manipulation and investigates whether female directors on boards of directors(Bo Ds) affect managers' real activities manipulation. Using a large sample of 11,831 firm-year observations from Chinese listed companies from the 2000 to 2011 period, we find that higher female participation on Bo Ds is associated with lower levels of real activities manipulation, and that this negative relationship is stronger when female directors have higher ownership. These results hold for a battery of robustness checks.Overall, our findings indicate that board gender diversity may serve as a substitute mechanism for corporate governance to curb real activities manipulation and thus provide interested stakeholders with higher quality earnings reports.

Electrochemically driven dynamic plasmonics

Dynamic plasmonics with the real-time active control capability of plasmonic resonances attracts much interest in the communities of physics,chemistry,and material science.Among versatile reconfigurable strategies for dynamic plasmonics,electrochemically driven strategies have garnered most of the attention.We summarize three primary strategies to enable electrochemically dynamic plasmonics,including structural transformation,carrier-density modulation,and electrochemically active surrounding-media manipulation.The reconfigurable microstructures,optical properties,and underlying physical mechanisms are discussed in detail.We also summarize the most promising applications of dynamic plasmonics,including smart windows,structural color displays,and chemical sensors.We suggest more research efforts toward the widespread applications of dynamic plasmonics.
