Formation of large-and medium-sized Cretaceous volcanic reservoirs in the offshore Bohai Bay Basin,East China

Based on the geological and geophysical data of Mesozoic oil-gas exploration in the sea area of Bohai Bay Basin and the discovered high-yield volcanic oil and gas wells since 2019,this paper methodically summarizes the formation conditions of large-and medium-sized Cretaceous volcanic oil and gas reservoirs in the Bohai Sea.Research shows that the Mesozoic large intermediate-felsic lava and intermediate-felsic composite volcanic edifices in the Bohai Sea are the material basis for the formation of large-scale volcanic reservoirs.The upper subfacies of effusive facies and cryptoexplosive breccia subfacies of volcanic conduit facies of volcanic vent-proximal facies belts are favorable for large-scale volcanic reservoir formation.Two types of efficient reservoirs,characterized by high porosity and medium to low permeability,as well as medium porosity and medium to low permeability,are the core of the formation of large-and medium-sized volcanic reservoirs.The reservoir with high porosity and medium to low permeability is formed by intermediate-felsic vesicular lava or the cryptoexplosive breccia superimposed by intensive dissolution.The reservoir with medium porosity and medium to low permeability is formed by intense tectonism superimposed by fluid dissolution.Weathering and tectonic transformation are main formation mechanisms for large and medium-sized volcanic reservoirs in the study area.The low-source“source-reservoir draping type”is the optimum source-reservoir configuration relationship for large-and medium-sized volcanic reservoirs.There exists favorable volcanic facies,efficient reservoirs and source-reservoir draping configuration relationship on the periphery of Bozhong Sag,and the large intermediate-felsic lava and intermediate-felsic composite volcanic edifices close to strike-slip faults and their branch faults are the main directions of future exploration.

The Relevance of International Financial Reporting Standards for Small and Medium-Sized Entities （IFRS for SMEs） in Swaziland

The purpose of this study is to explore the relevance of adopting International Financial Reporting Standards （IFRS） for small and medium-sized entities （SMEs） in Swaziland. The study further seeks to determine if IFRS for SMEs can be the solution to better reporting by local SMEs. There has been a growing need for different reporting standards for small firms and big firms over the years due to the unique challenges and attributes they face especially in the area of financial reporting. This research is based on a statistical analysis of questionnaires completed by accountants from SMEs in Swaziland as well as other stakeholders who have a direct or an indirect interest in the financial statements of SMEs. These stakeholders included audit firms and the financial institutions. The sampling rate of 10% was applied across each industry to come up with a sample of 60 SMEs. Furthermore, a 100% sampling rate on the other stakeholders was applied. These were nine financial institutions and eight audit finns. The findings from the study revealed that SMEs in Swaziland are having challenges with the current reporting framework but to some extent, the framework is suitable. Most SMEs are not aware of IFRS for SMEs, therefore the accounting profession in Swaziland （SIA） has a huge role to play in training auditors and accountants in the country. Overall, IFRS for SMEs is applicable in Swaziland.

Contract Mechanism of Water Environment Regulation for Small and Medium Sized Enterprises Based on Optimal Control Theory

The small and scattered enterprise pattern in the county economy has formed numerous sporadic pollution sources, hindering the centralized treatment of the water environment, increasing the cost and difficulty of treatment. How enterprises can make reasonable decisions on their water environment behavior based on the external environment and their own factors is of great significance for scientifically and effectively designing water environment regulation mechanisms. Based on optimal control theory, this study investigates the design of contractual mechanisms for water environmental regulation for small and medium-sized enterprises. The enterprise is regarded as an independent economic entity that can adopt optimal control strategies to maximize its own interests. Based on the participation of multiple subjects including the government, enterprises, and the public, an optimal control strategy model for enterprises under contractual water environmental regulation is constructed using optimal control theory, and a method for calculating the amount of unit pollutant penalties is derived. The water pollutant treatment cost data of a paper company is selected to conduct empirical numerical analysis on the model. The results show that the increase in the probability of government regulation and public participation, as well as the decrease in local government protection for enterprises, can achieve the same regulatory effect while reducing the number of administrative penalties per unit. Finally, the implementation process of contractual water environmental regulation for small and medium-sized enterprises is designed.

Harmonization of financial reporting of small and medium-sized enterprises in the Czech Republic

A current problem of the present-day accounting and financial reporting consists in aligning the accounting in small and medium enterprises. In July 2009 the International Financial Reporting Standard for small and medium-sized enterprises was issued, which extended the aligning possibilities also to small and medium enterprises considerably. If the standard is adopted by the national legislation, problems connected with the standard implementation in the national legislation will have to be solved as well as practical issues connected with making financial statements. At present the yields and the problems which can arise in connection with the standard application have to be focused on. A contribution of the standard application will be a better informative ability of financial statements on the international level. At small and medium enterprises this can contribute to better comanunication with banks, with investors, rating application are： parallel reporting according to national agencies etc. The problems connected with the standard regulations, differences between the national legislation and the standard, wide practice at keeping accounts and making financial statements and limited approach of small and medium enterprises to obtaining information and to training of their employees. Another problem can be a tight link between the trading income and the tax base, when small companies prefer rather the tax point of view.

Extemal Quality Control and its Impacts on Quality in Auditing Companies With Focus on Small and Medium-sized Audit Companies

After numerous spectacular balance scandals in the United States and Europe, an international discussion about the quality of audits as well as the necessity to raise the quality of financial audits arose. The United States of America responded to this discussion with the ＂Sarbanes-Oxley Act＂, while the European Union decreed the directive 2006/43/EC. The mentioned directive updated the statutory provisions for the professional guild of auditors to increase the quality of audits. In detail, it demanded an external quality-control-system combined with public supervision for the profession of auditors to ensure a better quality. Due to this fact, the audit companies now have to fulfill a large range of requirements to provide evidence of their consistent auditing-quality and furthermore of the quality standards within their company. Since many small and medium-sized companies are not able to fulfill these new requirements, the number of small and medium-sized audit companies decreases noticeably. This paper discusses the research results on the effects of external quality control^given by law---on the auditor market in Germany focusing on small and medium-sized audit companies. Additionally the research examines that, if the external quality control, which was one of the justifications of the conversions of the EU-directive 2006/43/EC is able to increase the quality in audit companies at all. Therefore it needs to be tested whether there is a uniform and fits all approach of quality in audits. The research questions and the tests were analyzed scientifically and confirmed in several expert interviews with four different expert groups in Germany.

Small and Medium-Sized Enterprises （SMEs） in Personal Services

Entrepreneurship has become an attribute of the current growth without business activities. Entrepreneurship is a global world. It is not possible to think about economic driving force of technological development and scientific research. It materializes knowledge and involvement of people and society. Expansion of business activities is a source of individual country＇s economic performance. It contributes to the development of people＇s living standards. In every market economy, it represents an irreplaceable role for small and medium-sized enterprises （SMEs）. A strong representation of＂micro-enterprises＂ can be found in the field of personal services. Companies within the course of their existence go through particular stages of their development--from their foundation through the stage of steady development. After this stage, there comes their decline that can develop even into their termination. We indicate this process as a company life cycle. The aim of the submitted project is to map the life cycle of particularly chosen companies providing accommodation and catering services and to find a mutual relation among observed quantities and their stable economic positions in the market. The analysis is based on the data of macro-economic character, the data about development of receipts in the sector, development of inflation, tempo of economic growth, and development of consumer prices. Out of a company, non-financial factors will also be considered. The core of the analysis is the stage of sustainable stability of the assessed companies. The point of the findings is revelation of the causes of risks of possible transition into the stage of termination due to the decline of services volume, decline of profitability, and long-lasting payment insolvency. The contribution of the project is to draw our attention to possible risks of critical situation development and to propose how to avoid them so that the company will not occur in financial straits. Achieved information could assist the company management to make relevant decisions.
