The core prices, consisting of the trend and the cycle, present regularities that a long-run cycle is embedded within two major cycles, and major cycle is composed of low-price period and high-price period, along with the rapid rise into a tower, and along with deep down into next trough; three sharply upward shocks occur by the events in a tower. Fluctuations in prices trend to slow cycles and expand the bands. It can be expected that tungsten price will highly stand over 17 a, and is is a advice that reducing production and restricting export maybe maintain a high price level.展开更多

Experiments revealed the influences of the structural design of the three-liquid-phase extractor and some key operational parameters on three-phase partition of two phenolic isomers, p-nitrophenol (p-NP) and o-nitrophenol (o-NP). The model three-liquid-phase extraction system used here is nonane (organic top-plaase)-polyethylene glycol (PEG 20UU) (polymer mlddle-phase)-(NH4)2SO4 aqueous solution (aqueous bottom-phase). It is indicated that agitating speed and retention time in three-phase mixer are key parameters to extraction fraction of nitrophenol. Dispersion band behavior is related to agitating intensity, and its occurrence does not affect the extraction fraction of target compounds. The present work highlights the possibility of a feasible approach of scaling up of the proposed three-phase extraction apparatus for future in- dustrial-aimed applications.展开更多

Network marketing is based on the network technology, including the whole process of marketing activities as a new form of marketing. In this paper, we analyze the issue from the listed perspectives. (1) Ultra space-and-time. The traditional marketing has very strong boundedness to the region, and this boundedness displays, the specifi c transaction can only be closed in the specific region, if the enterprise wants to expand the market share, only then establishes the retailing organization. (2) Interactivity. Network as a media, with the one-on-one interaction, this feature allows companies to basic communicate with consumers, and strengthen consumer participation, to determine the product form, function and the price. (3) The symmetry of information. Consumers can fi nd all kinds of that related products on the Internet information, there are plenty of time to judge the various products and prices. Companies will also be released in a timely manner on the Internet the company’s latest product information. Under this basis, we propose the new idea on the network marketing development direction that will help to build up the more efficient marketing system.展开更多

Firstly, investors appeared in the press sector, later on in the electronic media. One of the first groups presented in Poland was Orkla Media. The Norwegians launched a brand new regional daily. After subsequent failure they changed the pattern of business activity. When in 2006 Mecom bought out Orkla's shares, a new era began. The British fund was mainly interested in making their assets more profitable. The biggest shareholder of the regional press sector, however, is still Verlagsgruppe Passau (VGP). The German group appeared in 1993, in disguise of a Swiss company and next year took over eight regional dailies. In due course, VGP bought out a couple of more regional titles and became the leader of this sector of the market. Although the Germans were competing against the Norwegians and the Brits, they showed a different style of managing their assets. The author attempts to describe different patterns of business strategy in the press sector in Poland, examining each investor's behavior and the results of their efforts. This can lead to conclusions about the past activities as well as to predictions about the future of the market.展开更多

This paper tests the relationship between the reputation and the earnings quality. Through a partial correlation test and a regression test, I do find the evidence that the reputation is not only positively correlated with superior earnings quality, but also does have positive effect on superior earnings quality, as well as the superior total sales do in Chinese public companies.展开更多

Logistics connects the individual enterprise in the supply chain and it is the bond of mutual cooperation between enterprises. In that way, the logistics management becomes an important part of the supply chain management system naturally. However, it is not so long since the theory of supply chain management and logistics management put forward so they are still being refined. Besides, it is lack of green philosophy in the logistics management of the supply chain and effect of logistics on the environment and resource efficiency do not be considered synthetically. Yet, methods to solve the problem that customers return items and waste materials have been excluded from the enterprises and business strategy. With the awareness that people should protect the environment and conserve resources enhanced and governments increase the intensity of environmental regulations constraints, the theory and practice of green logistics management are valued by the foreign supply chain management and logistics management theory community and the business community gradually.展开更多

The introduction of the global strategy quadruple model truly links the three known strategy perspectives (namely, industry competition, resources and institution views) and performance. The model could assist in advancing the cause of sustainable competitive advantages. This study could assist scholars in addressing the three important research questions: (1) Why are some finns more innovative than others? (2) What effects do product, firm, industry, and market innovativeness have on business performance? and (3) Does the link between innovativeness and business performance depend on all or some of the innovativeness factors of product, firm, industry, and market? The presented set of four hypotheses, when tested, will result in a better understanding of the links and relationships among a firm's global strategy, innovativeness, and business performance. The quadruple model presented can be used to examine these relationships in general and in the context of innovation. It is anticipated that this paper will assist researchers, business management, and analysts in developing global innovation strategies.展开更多

Egypt has bilateral agreements with Italy since 2007. As a result of this relation, Italy has become a strategic partner for Egypt, gaining a growing importance in the Middle East. Egypt is, also, an important trading partner for the Italy. Political and economic relationship between Egypt and Italy has increased the interest in analyzing risks and opportunities for Italian firms that would like to operate in Egypt. However studies focused on this topic are still missing. With the aim to fill this gap, this article presents a study based on face to face interviews to some Egyptian senior-executives who manage in Egypt productive centres and representative offices of Italian finns. These interviews led to evidence opportunities and risks that Italian firms have to face operating business in Egypt.展开更多

We choose the Shanghai listed companies that adopted a diversification strategy in 2011 but realized a declined performance in 2012 as the study samples, and come to the following conclusions: (1) The macro environment will affect the implementation of the diversification strategy for some industries, such as extractive industry, wood furniture industry, rubber industry, and the building industry; (2) As to the sample of downward performance diversified companies, the shareholders' benefits transfer motivation is an important consideration. Further analysis shows that there are some differences in the degree of diversification, benefits transfer motivation, and the degree of income impairment when the sample is classified by corporate nature, growth stage, and firm size. The differences are more obvious in different corporate natures; and (3) A clear correlation between the management ability and the degree of income impairment is not found. But there are some correlations between ownership concentration and the degree of income impairment.展开更多

To well-understand the mechanism and effect of the action of IPM, the geometric theory of the involved semi-continuous dynamic systems is becoming more and more important. In this work, a geometric approach is applied to analyze the stability of the positive order-one periodic solution in semi-continuous dynamic systems. A stability criterion to test the stability of the order-one periodic solution is established. As an application, a stage-structure model involved chemical control is presented to show the efficiency of the proposed method. The sufficient conditions to insure the existence of the periodic solution are provided. In addition, the number and the stability of the periodic solutions are discussed accordingly. The simulations are carried out to verify the results.展开更多
