Since 1980＇s, innovations in management-have seen the application of several accounting techniques such as activity-based costing, balanced scorecard and target costing. However, subsequent surveys have shown that the application of these innovative management accounting techniques is not widespread. Indeed, the application of many techniques has been decidedly ephemeral. The authors suggest two important and interrelated reasons for the apparent failure to adopt such techniques. First, the absence of a conceptual framework needed to envision the collection and integration of multi-dimensional data needed in the modern organization. The second reason is the failure to exploit the data handling potentialities offered by modem computer systems. Reconstruction of contemporary management accounting system using insights from principles of events based accounting is offered as possible solution.展开更多

In clinical practice, imaging-derivedtumor metrics are routinely applied in oncologic management as an imaging biomarker. For example, the ResponseEvaluation Criteria in Solid Tumors （RECIST） are commonly used for tumor treatment response evaluation based on thedynamic changes in tumor size. However, the current cross-sectional images are interpreted qualitatively for lesioncharacterization, treatment response evaluation and prognostic prediction by highly trained radiologists, which hasincreasingly apparent limitations. Therefore, there is a demanding shift toward more quantitative imaging interpretation.展开更多

BIM technology, as a building information model, refines the process of each link of the construction project through the model, and uses the model to deal with possible problems in advance, so as to promote the smooth implementation of the construction project. In construction projects, relying on BIM technology to build visual entity models is convenient to check out problems in the early stage of the project, analyze problems and put forward concrete and feasible solutions, which will greatly reduce the repair probability, improve the construction site management quality of construction projects, and finally promote the smooth completion of the project. Next, the article firstly gives an overview of BIM technology, then analyzes the application status of BIM technology, and finally puts forward some suggestions on the specific application of BIM technology in site construction management, hoping to promote the application of BIM technology in construction engineering.展开更多

Field experiments, with three nitrogen levels （0, 150 and 300 kg ha-L） and two ratios of basal to topdressing （8：2 and 5：5） with two super rice cultivars （Yliangyou 2 and Wuyunjing 23）, were conducted in the Baolin Farm, Danyang Country, Jiangsu Province, China, in 2011 and 2012. Effects of N fertilizer rates and ratios on morphology of whole plant, morphology traits in basal intemodes and culm＇s physical strength parameters were investigated at 20 d after full heading stage. LI of Yliangyou 2 was significant greater than that of Wuyunjing 23 due to larger bending moment by whole plant （WP） with higher plant height and gravity center height. With higher volume of N fertilizer, LI of two super rice cultivars was increased conspicuously. However, no significant effect was detected with increase of panicle fertilizer ratio. The size of breaking strength （M） in basal intemodes was the key factor determining LI among N fertilizer treatments. Correlation analysis revealed that M value was positively related bending stress （BS） of Wuyunjing 23 and section modulus （Z） of Yliangyou 2, respectively. The higher N fertilizer levels induced reduction ofBS of Wuyunjing 23 due to weak culm and leaf sheath plumpness status and reduced Z of Yliangyou 2 owning to small diameter and culm wall thickness, consequently, influencing their M indirectly. These results suggested that breaking strength was the key factor influencing LI with increase of N fertilizer levels. However, the lodging-related morphology mechanism was different with genotypes. Culm wall thickness and diameter in basal internodes of indica super rice and culm and leaf sheath plumpness status of japonica super rice influenced breaking strength, as well as lodging index, respectively.展开更多

It is the responsibility of every citizen to rationally utilize and protect these precious resources. However, with the deepening of China's economic construction and the acceleration of the urbanization process, the demand for water resources in social production and life is increasing. At the same time, the unreasonable discharge of industrial wastewater and urban domestic sewage has caused many rivers and lakes in our country to be polluted to varying degrees, the water quality is continuously declining, small-area rivers and lakes are gradually disappearing, and "milk river" and "dye river" are appearing one after another, seriously damaging the ecological environment and breaking the situation of harmonious development between human beings and nature. In March 2017, the state officially issued the "Opinions on the Full Implementation of the River chief system" and in March 2021, the "Law of the People's Republic of China on the Protection of the Yangtze River". By fully implementing the concepts of green development and ecological construction, the state realizes the sustainable development of water resources and the lives of rivers and lakes in China, which is an important measure to improve the water environment, restore the ecological environment and protect water resources. At present, the management of river chief system in many areas of our country is still at the stage of practical exploration, and there are many problems. This paper will focus on the green river and lake management model under the background of river chief system, aiming at further strengthening the protection of rivers and lakes in our country.展开更多

The application of big data in environmental pollution control is a brand-new perspective. It can not only transform the traditional single and extensive management mode into an integrated mode of intensification and intelligence. Environmental big data can effectively reduce energy consumption and pollutant emissions by monitoring all aspects of enterprise production activities and realizing information sharing;But also can promote the improvement of the ecological environment and improve the efficiency of the ecological protection work.展开更多
