Cloud ERP

2019-12-14 15:14:20 | 日記
下面为大家整理一篇优秀的essay代写范文- Cloud ERP,供大家参考学习,这篇论文讨论了云ERP。随着云计算的飞速发展,各种云概念的产品纷纷问世,ERP市场自然也无法“幸免”。云ERP是以云服务方式实现ERP相关功能的一种新型ERP应用模式,可有效满足企业日益强烈的ERP应用需求,从根本上解决传统ERP投资成本高、实施成功率低、运维难度大等瓶颈问题,从而提升企业核心竞争力,助力企业转型升级。企业在应用与发展云ERP的同时,也面临着新的挑战。

With the rapid development of cloud computing, a variety of cloud concept products have come out, the ERP market is not immune. Cloud ERP is a new ERP application mode that realizes ERP related functions in the way of cloud services. It can effectively meet the increasingly strong ERP application demand of enterprises, fundamentally solve the bottleneck problems such as high investment cost, low success rate of implementation, and great difficulty in operation and maintenance of traditional ERP, so as to improve the core competitiveness of enterprises and facilitate the transformation and upgrading of enterprises. Enterprises are facing new challenges while applying and developing cloud ERP. Cloud ERP has a large space for growth, which is worthy of further exploration and research.

Cloud computing delivers traditional IT products to users as services over the Internet through SaaS, PaaS and IaaS service models.

Providing computer infrastructure to users through the network is the lowest and most basic service. It provides users with standardized services such as basic storage resources, servers, and computing power on demand.

Users do not need server hardware and can directly use the PaaS platform to develop their own applications. At the same time, applications developed using the PaaS platform can better build enterprise application platforms with service-oriented architecture.

Also known as the software operation service model, it is an implementation model of cloud computing and a way to provide software services through the Internet.

The traditional ERP client is installed on the client's local computer and must be operated and used through the local computer. There are significant limitations to the mobile and anytime, anywhere needs of modern organizations. And cloud-based ERP users can not only use the system in the internal LAN of the enterprise, but also use the system through the external wan. As long as there is a network, the system can be used anytime and anywhere, and timely update and review data, greatly improve the efficiency of the system and work efficiency.

Traditional ERP software has to go through a long period of requirements and implementation process. The hardware input and labor cost required in this process are very high, but after the use of the ERP system based on the cloud computing platform, the enterprise will not need to configure a large number of professional technical personnel to track and communicate, eliminating a lot of tedious work and improving work efficiency.

Traditional ERP requires a one-time buyout of software packages and concurrency, while cloud ERP can gradually increase the number of users according to the development needs of modern organizations, adding one user for each employee to increase the cost of cloud applications and services, and even directly reduce the number of ERP users when employees are reduced. In addition, the modules of cloud ERP can also increase or decrease at any time according to the change of organizational structure and business scale.

Cloud ERP has a significant promoting effect on the modern management system and efficiency of enterprises in the new era. Smes can rely on the model of network leasing to obtain ERP services, further effectively control the implementation difficulty and cost of ERP, and also develop services into the international market system. In view of the actual situation of resources at the group level and ERP system precipitation of internal single enterprises, cloud technology has brought ideal solutions for the development and deployment of ERP software, thus providing reliable technical support for the efficient promotion of process chain driven ERP enterprise management.

However, in the process of cloud ERP promotion and application, new problems will inevitably be found, and how to solve and deal with these problems is the focus of the application. How the application of cloud ERP will develop in the future and the direction of development depend on the solution of these problems.

Cloud computing is very flexible and convenient, but data privacy and security issues in cloud computing have long been a concern. First of all, data in cloud computing depends on network transmission, and network security technology requirements are very high; Second, multi-tenant common services, data management requirements are also very high, data leakage can not occur; Finally, for cloud computing providers, users' information and data are transparent, so cloud computing providers must take effective measures to ensure the security of the cloud ERP system.

As a complex organization management system, ERP involves the financial, sales, procurement, inventory, quality and other business of organization management. It is a thorny problem to meet the needs of users in an all-round way. Moreover, as an emerging technology, cloud computing market is still immature, which determines that customers are likely to be dissatisfied with some aspects of cloud ERP. But once users select a vendor, they are almost bound to it, making it difficult to migrate data to other cloud platforms.

At present, many organizations and institutions in China have weak management foundation, weak management consciousness and backward management concept, which are inconsistent with or even conflict with the advanced management ideas represented by cloud ERP, restricting the development of cloud ERP. Cloud ERP implementation involves all levels within the organization, need the coordination between each department each link, at the top of a powerful drive, interactive communication between departments, a clear business process, the system of security and full of non-technical factors such as management thought transformation, the lack of any one can let cloud ERP implementation of paralysis.

Compared with the traditional ERP system, the cloud ERP system is more convenient and flexible. At the same time, it provides enterprises with a modern enterprise management mode with less input cost, but can meet all kinds of requirements at any time, which is the general trend of the future development of ERP in the big data environment. Due to the low cost of using the system, more and more enterprises will use the cloud ERP system, which can serve more enterprises, which has played a positive role in promoting the development of enterprises. Although cloud ERP overcomes many disadvantages of traditional ERP, it is not omnipotent, and it also has disadvantages and faces new challenges and risks. Therefore, users fully understand the connotation of cloud services and challenges of cloud ERP before implementing cloud ERP, so as to ensure the successful implementation of cloud ERP. Although cloud computing services are becoming more and more mature and recognized by more and more people, cloud ERP has a large space for growth, which is worthy of further exploration and research.

投资者在低碳经济和可持续发展目标融资方面的作用

2019-12-14 15:11:48 | 日記
这些目标分为两个主要领域——社会和环境。一些社会目标旨在满足基本需求。广泛的环境目标旨在通过改变全球经济在全球的运作方式,将世界保持在关键的全球安全边界内。这17项全球目标及其169个组成部分目标自下而上地设计,以建立大多数人希望的未来,没有贫穷,地球受到保护,所有人都享有和平与繁荣。这17个目标共同构成了一个综合的一揽子计划。没有社会目标,环境目标就无法实现,反之亦然。

投资者在低碳经济融资中的作用:

金融体系由机构参与者(包括监管机构、银行、保险公司、股票和债券交易所)以及数十亿个个人市场参与者组成。投资者包括机构投资者和私人投资者,为普通民众提供超过80%的就业机会。

调动不同行为者的大规模低碳投资将需要在地方一级发展有利的治理结构。由于目前低碳经济融资的投资需求与实际投资存在较大差距,私营部门的投资者不仅拥有更重要的投资资源,尤其是在投资萎缩时期。公共预算,但也常常被广泛认为为项目带来额外的效率、管理能力和业务权力。

关于资金来源,现实情况是,政府需要依靠私营部门的投资者提供大部分必要的资本,利用公共财政促进、激励和降低私人资金流动的风险。

投资者在鼓励公司应对风险和利用气候变化带来的机遇方面发挥着两个重要作用。首先是利用股东的影响力,鼓励公司采取更积极主动的方法来管理气候变化带来的风险和机遇。第二,将气候变化风险和机会明确纳入"主流"投资分析进程。投资者本身可以在加强减少温室气体排放的公共政策措施中发挥作用。

为企业创造的机会:

根据商业和可持续发展委员会的研究,到2030年,实现全球目标为私营部门带来至少12万亿美元的经济奖励,并可能增加2-3倍。超过50%的奖金位于发展中国家。在委员会审查的四个经济体系中的60个市场"热点"中,有15个——粮食和农业、城市、能源和材料以及健康和福祉——占该奖项的50%。到2030年,实现这四个经济体系的全球目标可创造3.8亿个新的就业机会,其中近90%在发展中国家。其中一个市场热点,经济适用房,占这些工作岗位的近五分之一(7000万)。气候变化等环境成本的定价使奖金的"实际"规模又增加了40%。

委员会对可持续发展至关重要的其他部门,包括信息和通信技术、教育和消费品,进行了保守的扩展。这表明,在一个追求全球目标的世界,每年可以创造8万亿美元的价值。

一旦公司支付了反映社会和环境外部性的"全"价格,那么其财务表现将成为投资者了解公司在全球目标上相对表现的主要信号。已经将其资源使用和劳动力管理与全球目标保持一致的先动者将在可持续竞争领域拥有 5-15 年的优势,并超越竞争对手。

它开辟了新的机遇和巨大的效率收益;它推动创新;提高声誉。凭借可持续发展的声誉,公司吸引和留住员工、消费者、B2B 客户和投资者,并确保其运营许可。

如何写好paragraph

2019-12-14 15:08:41 | 日記
对于英文论文写作来说,paragraph是重中之重。写不好paragraph的话,那么论文是拿不了高分的。当然,要想写好paragraph,那么大家就得运用一些技巧了,今天我们就分享一些写好paragraph的技巧给大家,希望可以帮助大家写出满意的论文。

写好paragraph,其实就两点,写好主题句和写好推展句。说起来很简单,做到其实不容易,先说主题句,它是段落的中心,整个段落都是围绕它展开的。主题句一定是放在段落开头,就是开门见山的告诉读者,我这段要讨论什么问题,之后再加以说明,让文章逻辑通顺,结构清晰。主题句要传达主题和中心思想,表达的时候要注意用词,争端都是围绕主题句来写,所以主题句要涵盖整段的内容,不能偏颇,也不能走题。这对文字的要求相当高,一开始或许不容易写好,但多加练习之后,肯定会有所提高。

说完了主题句,下面来说推展句,推展句和主题句不同,推展句本身不需要做进一步的说明,句子之间的关系要求相互独立同时有内在联系。顾名思义,推展句需要对主题句进行进一步的分析说明,从某个方向或是逻辑层面来推展主题。推展句要从不同的角度和维度进行思考,才能使文章整体显得有层次、不单调,也更容易展现作者的文字功底和对所收集素材的吸收整理能力。因此写好推展句,也是给老师留下好印象从而获得满意的论文分数的一个途径。

以上就是关于paragraph的写作讲解,建议大家多去阅读相关文章,从别人的文章中汲取精华,学会别人的写作方法。

The British personal income tax system

2019-12-14 15:02:27 | 日記
本篇paper代写- The British personal income tax system讨论了英国的个人所得税税收制度。在英国,个人所得税的费用扣除标准并不是固定的,而是每年调整的。英国的财政部会在每年的3月公布下一个财年的费用扣除标准。这个额度的确定,是在充分考虑了当前年度的物价指数、人均收入等指标后决定的。为了更好地照顾低收入的家庭,英国的费用扣除标准还可以在夫妻、伴侣间转移。在所适用的税率均为英国个人所得税最低税率的夫妻、伴侣,如果有一方的年收入低于费用扣除标准,则可以将自己费用扣除标准的10%转移给对方,用于抵扣。另外,英国个人所得税的费用扣除标准还有自动调节的功能。本篇论文代写范文由51due代写平台整理,供大家参考阅读。

The reform of individual income tax is one of the social hot spots at present. The reason is that the income gap between different groups keeps widening, so people need it to be more effective as a means of redistribution to promote better social development. The reform is still in progress. We need to learn from foreign practices and experience and optimize the individual income tax law in light of our own circumstances. This paper aims to find out the problems in China's individual income tax system by studying the British individual income tax system and put forward reasonable Suggestions.

Individual income tax is one of the most important taxes directly related to the national economy and people's livelihood. On October 31, 2018, the fifth session of the standing committee of the 13th National People's Congress voted to amend the individual income tax law. On December 22 of the same year, the state council officially issued the interim measures for the special additional deduction of individual income tax, marking the beginning of the reform of individual income tax.

In 2018, an important step was taken in the reform of individual income tax by combining comprehensive and classified methods. However, in the past decade, with the continuous development of China's material and economic development, the drawbacks of the individual income tax system have gradually emerged, and the regulatory role of tax has not been better played, so the reform is still a long way to go.

Different from China, Britain is the first country to levy individual income tax in the world, and individual income tax is also its core tax. In terms of individual income tax system, the UK has rich experience and advanced methods that are worthy of our reference.

Over the past 40 years of reform and opening-up, China has created many economic miracles, and many people have created their own wealth legends. However, the gap between the rich and the poor is also expanding. According to a recent survey by the people's bank of China and the southwestern university of finance and economics, the top 5 percent of Chinese actually control half of the country's savings, or 472,000 yuan per person. 55% have an average deposit of only 42,000 yuan; And 40 percent of the people have zero savings per capita. In addition, the revised individual income tax law came into effect on January 1, 2019, and the ministry of finance's fiscal revenue and expenditure for the january-february period showed that the individual income tax revenue was 232.6 billion yuan, down 18.1 percent year on year. Then, on March 21, the ministry of finance, the state administration of taxation and the general administration of customs jointly issued the announcement on deepening the relevant policies of value-added tax reform, indicating that the country is reducing the proportion of indirect tax and gradually increasing the proportion of direct tax. As things stand, the real estate tax is about to be enacted, but it is generally recommended not to tax first homes and improvement housing, thus reducing the tax base. In addition, our country does not meet the time and condition of collecting estate tax at present. As the most typical direct tax, the government should increase the income tax revenue of high-income groups through reform on the premise of reducing the tax burden of middle and low-income groups. In this way, we can narrow the gap between the rich and the poor, slow down the decline of personal income tax, increase the proportion of direct tax, and help the government to obtain some fiscal revenue.

In the UK, the standard for deducting expenses from personal income tax is not fixed, but adjusted annually. Britain's Treasury publishes the deduction for the next financial year in March. This quota is determined after fully considering the current year's price index, per capita income and other indicators. In order to take better care of low-income families, the expense deduction standard in Britain can also be transferred between husband and wife and partners. If one party's annual income is lower than the expense deduction standard, he/she can transfer 10% of the expense deduction standard to the other party for deduction.

The UK individual income tax expense deduction standard also has the automatic adjustment function. In 2018, for example, UK tax law stipulates that the annual net income of the high-income group is still more than 100,000 pounds after deducting individual contributions to pensions and charities, and the deduction standard for expenses above 100,000 pounds will be reduced by 1 pound. The cost deduction for 2018 is £11,500, which is automatically adjusted to zero when net income reaches £123,000.

In terms of tax rate, there are three levels of individual income tax rate in the UK, namely Basic rate, Higher rate and Additional rate. The taxable income at these three rates varies widely: Basic rate for individuals earning 11,500 to 33,500 pounds, Higher rate for individuals earning 33,500 to 150,000 pounds, and Additional rate for individuals earning more than 150,000 pounds. Among them, the Normal rate and Dividend rate of Basic rate (20%) and 7.5% are directly increased to Normal rate (40%) and Dividend rate (32.5%) from the Higher rate. Compared with the Higher rate, the subsequent Additional rate increases are much more flat (45%) and 38.1% respectively.

Because of the earlier economic development, the tax category setting of Britain is also more perfect. There are capital gains tax, inheritance tax and other taxes that have not been set in China. In our country belongs to the individual income tax items of property transfer income, other income in the United Kingdom are capital gains tax items. Capital gains tax in Britain, like income tax, is set to a fee deduction standard and a progressive rate.

In the mode of collection, Britain's individual income tax is a comprehensive collection system. Because of the comprehensive levy, the expense deduction standard in the UK is deducted for all net income, including rent income, interest income and dividend income. After the promulgation of the interim measures for the special additional deduction of individual income tax, China changed from a classified collection system to a mixed collection system combining classification and synthesis. However, the expense deduction standard still only applies to the income from wages and salaries, while the income from remuneration for labor service, remuneration from author's remuneration, income from royalties and income from property lease are deducted at the rate of RMB 800 per time or 20% of the income amount.

With the development of our economy, the cost of living increases every once in a while. The expense deduction standard of individual income tax in China is determined by the standing committee of the National People's Congress. This is more authoritative, but not suitable for our current economic situation. Consider, as in Britain, taking into account the annual monetary situation in the setting of the expense deduction standard. Or the standard for deducting expenses for each year; Or set up a calculation formula in which the inflation rate is the independent variable and the expense deduction standard is the dependent variable.

The expense deduction standard of individual income tax in Britain can also be used for reference for the automatic adjustment of high-income groups. The expense deduction standard can effectively reduce the tax burden for the middle and low income groups, but it will not have a great impact on the high income groups. Adjusting the deduction standard for expenses according to the annual net income of high-income groups can not only give play to the function of tax adjustment, but also increase the fiscal revenue.

In theory, the more progressive the tax rate, the stronger the redistributive effect. However, this is based on the assumption of perfect market mechanism, low cost and symmetrical information. In reality, these assumptions, especially in developing countries, are hard to make. Thanks to the underground economy, high-income groups can avoid high taxes at very low cost. In addition, China's current tax collection and management force is weak, in order to ensure the timely and complete tax, it is bound to increase the cost of collection and management. All these result in the effect of redistribution can not play an effective role. The tax rate structure in the UK is simple and there are large differences between tax rates. The first is to further expand the proportion of middle income class and the second is to reduce the cost of collection and administration. Simplifying the tax structure, adjusting the difference of tax rates, supplemented by corresponding tax incentives, can not only reduce the tax burden of middle-income groups, but also reduce the pressure and cost of tax collection and management departments.

The income source of high-income group is very complex, and it should be recognized that "high salary" and "high income" are two distinct concepts. Much of the income of high-income groups is realized through capital gains. In view of these capital gains, our country is levied by the 20% tax rate at present. For the high-income group whose capital gains account for a higher proportion of income, such tax rate is relatively low and thus becomes one of the channels for them to avoid tax. The introduction of capital gains tax, through the establishment of expense deduction standards and progressive tax rates, can not only help low - and middle-income groups with few sources of capital gains to reduce the tax burden, but also to some extent to avoid high-income groups to avoid tax avoidance.

After the promulgation of the interim measures for the special additional deduction of individual income tax in China, the tax burden of working families mainly based on wages and salaries has been greatly reduced, but the tax burden of some highly educated families mainly based on remuneration for labor service, remuneration from author's contribution and income from royalties has not been effectively reduced. Instead of a mix levy, a combination levy, as in Britain, is a standard deduction for all income. This can not only avoid unfairness, but also enhance the authority of the tax law. Comprehensive collection system is the world's advanced collection model, but also the direction of China's individual income tax reform.

The British experiential approach to teaching

2019-12-14 14:58:20 | 日記
下面为大家整理一篇优秀的essay代写范文- The British experiential approach to teaching,供大家参考学习,这篇论文讨论了英国的体验式教学方法。英国艺术设计教育独具特色,尤其注重学习过程中的体验和探索以及实践和创新。在欧洲的各个博物馆、美术馆,经常可以看到正在上美术课的学生。学生在美术馆里的课堂上始终处于轻松愉快的氛围当中,思维也处于一种开放性的、活跃的状态。这种在美术馆里上课的方式是最理想的艺术教育形式,学生的审美得到了潜移默化的熏陶和培养,逐渐树立起正确的审美观念和健康的审美情趣。

British art and design education has its own characteristics, focusing on experience and exploration as well as practice and innovation in the learning process.

In European museums and art galleries, it is common to see students having art classes. Students are always in a relaxed and happy atmosphere in class in the art gallery, and their thinking is also in an open and active state. This way of teaching in the art gallery is the most ideal form of art education. Students' aesthetic appreciation has been influenced and cultivated subtly, and the correct aesthetic concept and healthy aesthetic taste have been gradually established.

In 1922, CAI yuanpei discussed the methods of aesthetic education implementation and related problems in the article "methods of aesthetic education implementation", and divided aesthetic education implementation into three parts: family education, school education and social education. These three parts run through each other and complement each other, forming a complete flow chart of aesthetic education.

Students usually sit on the ground in an art gallery or museum, listening to their teacher describe the story behind the artwork or the characteristics of its creation. Some art galleries also provide some corresponding models or teaching AIDS for students to touch and assemble with their own hands, which is helpful for students to understand the structural relationship of art works more concretely. Appreciation goes hand in hand with creation. Teachers usually organize and guide students to think about and expand discussion on problems according to the course content. History, geography and other disciplines can be integrated into artistic creation. In this process, the teacher guides the students step by step to accept the new content, express their feelings, and continue to extracurricular learning and thinking. Students can constantly accept new content, new ideas, burst out the spark of creativity.

Published in 1795, Schiller's aesthetic education letters, is the first in the history of western systematic exposition of aesthetic theory, first proposed the concept of "aesthetic education", aesthetic education is through the people's aesthetic image, cultivate emotion of beauty and purity of mind, in order to achieve the full freedom and harmonious development of human beings. The author's bold creativity, rigorous thinking and tentative innovation are accumulated gradually in the process of his observation and experience.

British art education does not pay too much attention to painting skills, in contrast to pay more attention to students' creative thinking and personality expression. Does not require the technical drawing ability, and requires the student to see, think, do more, more attention to the student art learning process rather than the result. When doing design tutoring, teachers do not limit the topic and expression, very respect students' ideas, encourage students to break through their own conventional creative mode, through various forms of experiments, open the idea and deepen the design. In the process of teaching, teachers encourage students to break through the conventional creative mode and try a variety of possibilities, so that the design scheme gradually takes shape in the process of thinking, constantly optimizes, and finally forms the scheme. This reflects the freedom and preciseness of British art design education and teaching.

Students are the main body of learning, the teaching focus is to develop students' independent learning ability and research ability, focusing on how to guide students to learn effectively, let students master the method of learning. In this process, teachers respect students' individual wishes and support their individual expression, let students think independently and solve questions in practice, improve their thinking mode and improve their research ability in the process of repeatedly asking questions for evidence.

The main purpose of teaching is to cultivate students' learning initiative and exploration spirit, especially to improve students' ability of attention, observation, imagination and other aspects, so that students' learning initiative becomes stronger, and they clearly know what they want to learn and how to obtain knowledge. British teachers do not require students to have sketches with painting skills, nor do they pay much attention to how perfect students' skills are. Instead, they focus on stimulating students' interest and encouraging them to try again and again to break through their regular creative modes. Try to perfect the form of conception and expression through various and even outlandish methods. Teaching methods are orderly and flexible, highlighting the characteristics of "learning by doing, learning by doing" in art design teaching, reflecting the freedom and rigor of art design education. Under this mode of education, students cover a wide range of subjects, improve their independent research ability and comprehensive application ability, and have a clear idea of future development plans.

There is a good art atmosphere in the art gallery, and students can appreciate the art works closely, which is conducive to students' deeper understanding of art and teachers' better teaching. In teaching practice, teachers should integrate the resources of social education, which can solve the problem of single teaching content and teaching methods, provide students with different new perspectives and multi-dimensional information guidance, and make practical training more specific and in-depth. China's art design education and teaching should continue and improve the double-track teaching form from static teaching to static and dynamic comprehensive teaching mode. Practice in design, then reflect and deepen design from practice. In this process, attention is paid to the cultivation of students' practical ability and innovation ability, so that students can take the initiative to acquire knowledge and become knowledge explorers.

The British experiential teaching method can imperceptibly cultivate students' ability to appreciate and create beauty, which will have a positive and far-reaching impact on the future art education and teaching in our country. Through the analysis of the teaching form of art in Britain and the study of design courses in British universities, we have a clearer understanding of art design teaching and a deeper thinking. Based on the actual situation of our country, this paper explores some inspirations that are beneficial to the construction and development of art discipline in our country, so as to promote the optimization and perfection of the education and teaching of art design specialty in our country.
