The traditional human comfort meter has the following defects: the interface is not uniform;the operation is cumbersome and complicated;the interface is unfriendly, and the stability and adaptability are poor. This paper presents a design scheme for human comfort instrument based on embedded system, using S3C2440 embedded development board and the sensors to collect the real-time temperature, relative humidity and wind speed data and to process the collecting data;then obtaining the human body comfort value according to the basic algorithm of human body comfort instrument;giving the human comfort conclusion according to the diastolic index range of human comfort, and showing the temperature and humidity, wind speed, comfort value and conclusion through writing the Qt graphical user interface program. At the same time, the human comfort instrument has the data storage function. The human comfort instrument is high in integration, strong in real time, high in sensitivity, stable and reliable, and it meets the development goals of the intelligent meteorological service, and meets the demand of the meteorological service that is closer to life, and it has broad development prospect. 展开更多

Operational analytics is all about answering business questions while doing business and supporting business users across the organization, from shop floor users to management and executives. Therefore, business transactions and analytics must co-exist together in a single platform to empower business users to drive insights, make decisions, and complete business processes in a single application and using a single source of facts without toggling between multiple applications. Traditionally transactional systems and analytics were maintained separately to improve throughput of the transactional system and that certainly introduced latency in decision making. However, with innovation in the SAP HANA platform, SAP S/4HANA embedded analytics enables business users, business analysts, and management to perform real-time analytics on live transactional data. This paper reviews technical architecture and key components of SAP S/4HANA embedded analytics. This paper reviews technical architecture and key components of SAP S/4HANA embedded analytics. 展开更多

How U.S. Antidumping Actions Affect China's Inward and Outward FDI

This paper presents an empirical study of how U.S. antidumping (AD) actions against China affect China 's inward and outward foreign direct investment (FDI) based on the international division of labor model. Our findings are as follows: (1) The U.S.-China trade deficit has been widened by both downstream firms in China established through vertical FDI and also inward enterprises established through horizontal FDI. The widening deficit in turn exacerbates vitriolic complaints in the U.S. about injury to its industries. This will lead to further U.S. AD actions discouraging FDI in China. (2) U.S. AD cases against China have negatively impacted China's metal manufacturing, chemical and, especially, textile industries in terms of exports and inward FDI. From 2004 to 2009, the share of total inward FDI going to China's manufacturing sector has dropped drastically by almost 20 percent. This supports predictions made using the international division of labor model. (3) With U.S. AD actions against Chinese products on the rise, Chinese firms chose not to circumvent such barriers through outward FDI in the U.S. but rather through outward FDI in tax havens. Such a pattern of outward FDI is not helpful for China to establish its own successful industrial development model. 展开更多

Background: In 1996, Wahaha, Danone and BNP (Hong Kong) jointly invested in and incorporated 5 companies to manufacture Wahaha brand products, including purified water and eight-treasure porridge. Wahaha holds 49% equity interests in these companies, while Danone later became the dominant shareholder with a 51% stake after acquiring shares held by BNP in the aftermath of the Asian financial crisis. Danone then proposed to transfer the Wahaha brand to a joint venture but did not succeed. Subsequently, a trademark usage contract was signed by both parties instead. In the ensuing years, the Wahaha Group established non-JV companies in west China, central China and the Three Gorges reservoir area. These companies had RMB 5.6 billion of total assets as of December 31st, 2006 and made a net income of RMB 1.04 billion in that year. On April 3rd, 2007, Danone intended to force a deal by which it could acquire 51% equity interests in those non-JV companies for a sum of RMB 4 billion. Wahaha Chairman Zong Qinghou later complained that he and Wahaha fell into a trap set up by Danone. Both parties have since engaged in a lengthy "war of words", thereby arousing a grand debate on China's FDI policies. 展开更多

This paper has empirical character and investigates locational determinants of the inward foreign direct investment (FDI) stock among 50 states of the United States. The analysis uses annual data for the period from 1997 to 2007. The study identifies several state-specific determinants of FDI and investigates the changes in their importance during the study period. Our results show that among the major determinants, the real per capita income, real per capita expenditure on education, FDI related employment, plus real research and development expenditure are found to have a significant positive impact on inward FDI. There is also evidence that manufacturing density and unionization exert a small positive impact on inward FDI. In addition, per capita state taxes, the share of scientists and engineers in the workforce, real capital expenditure, and unemployment rate exert a negative impact on FDI. 展开更多

Foreign direct investment (FDI) has great function to the growth of the economy in various countries. The beneficial policies of the foreign capitals are the main means to various countries to absorb FDI. Utilizing this means appropriately and designing beneficial policies, which can make the host country get the maximized revenue of utilizing FDI, are the key to absorb FDI effectively. In this paper, we set up a game model between the level of the host country's beneficial policies and the scale of FDI, and analyze what the key factors that influence the level of host country's beneficial policies are and how to decide the level of beneficial policies according to these key factors. 展开更多
