Wettability was evaluated by contact angle with the Wilhelmy plate method. Water repellency was likely to be present under permanently vegetated land, but less common on tilled agricultural land. It was mostly prevalent in the topsoil, especially in coarse-textured soils, and decreased in the subsoil. However, the depth dependency of wettability could not be derived from the investigated wide range of soils. The correlation and multiple regression analysis revealed that the wettability in repellent soils was affected more by soil organic carbon (SOC) than by soil texture and pH, whereas in wettable soils, soil texture and pH were more effective than SOC. Furthermore, the quality of SOC seemed to be more important in determining wettability than its quantity, as proofed by stronger hydrophobicity under coniferous than under deciduous forestland. Soil management had a minor effect on wettability if conventional and conservation tillage or different grazing intensities were considered.展开更多

Therefore, it is of great significance to study earnings management and its influencing factors in order to restrict earnings management and ensure the quality of accounting information. This paper studies the impact of internal control related earnings management, and incorporates equity incentives into the impact analysis framework of internal control related earnings management, and studies the effect of equity incentives on the relationship between internal control and accrued earnings management.展开更多

The establishment of a new powerful trend in investments produces strategic shifts in strategic management. Shareholder wealth maximization way of thinking is changing to stakeholder wealth maximization where a company's value management system is based not only on economic profit maximization, but also on environmental, social, and governance (ESG) maximization. There is especially a high need for a management system that can be used by mergers and acquisitions (M&A) practitioners during integration process. There is a critical need for metrics which can trace the interests of all stakeholders, because to achieve success in integration, it is no longer acceptable for management to focus solely on the needs of one or two stakeholder groups. In this article, the authors have introduced two frameworks: sun cube and stakeholder relationship matrix. These tools can be useful in mergers and acquisitions (M&A) process for conducting a stakeholder analysis.展开更多

We find that the loss llsted companies did not make any significant profit-making earnings management during the first loss year, while in the turning-around year, they made clear profit-making earnings management. This shows that the loss listed companies in order to avoid continuous losses, to prevent the company's stock price continued to decline, will be in the loss-making annual profit management.展开更多

Newspapers have begun to employ such technologies to bolster audience numbers and to attract more advertisers. The comparison of the old revenue model of newspapers with a new emerging business model utilizing newer technologies allows a framework of a possibly new model to be applied to older models. Media are desperate to gain audiences lost in the past decade and trying to reformulate their current business models to reflect new technology. The way media are framing the third screen as a possible savior to their current business model shows that the media realize the old model of revenue through advertising and subscriptions is antiquated. This paper presents a new business model for media by embracing new technologies and adds to current scholarship of media management in a new technologically inclined world.展开更多
