The aim is to remove copper from a pyrite cinder by optimizing the chlorination roasting process using re-sponse surface methodology （RSM） and the reaction mechanism of chlorination roasting based on thermodynamic calculation was discussed. A quadratic model was suggested by RSM to correlate the key parameters, namely, dos-age of chlorinating agent, roasting temperature and roasting time to the copper volatilization ratio. The results indi- cate that the model is well consistent with the experimental data at a correlation coefficient （R2） of 0.95, and the dosage of chlorinating agent and roasting temperature both have significant effects on the copper volatilization ratio. However, a roasting temperature exceeding 1170 ~C decreases the volatilization ratio. The optimum conditions for removing copper from the cinder were identified as chlorinating agent dosage at 5%, roasting temperature at i155.10 ℃ and roasting time of 10 min; under Such a conditiom a copper volatilization ratid of 95.16% Was a- chieved from the cinder. Thermodynamic calculation shows that SiO2 in the pellet plays a key role in the chlorine re-lease from calcium chloride, and the chlorine release reactions cannot occur without it.

This study aims to fill the gap in the literature by specifically investigating the impact of country risk on the credit risk of the banking sectors operating in Brazil,Russia,India,China,and South Africa(BRICS),emerging *** specifically,we explore whether the country-specific risks,namely financial,economic,and political risks significantly impact the BRICS banking sectors’non-performing loans and also probe which risk has the most outstanding effect on credit *** do so,we perform panel data analysis using the quantile estimation approach covering the period 2004–*** empirical results reveal that the country risk significantly leads to increasing the banking sector’s credit risk and this effect is prominent in the banking sector of countries with a higher degree of non-performing loans(Q.25=−0.105,Q.50=−0.131,Q.75=−0.153,Q.95=−0.175).Furthermore,the results underscore that an emerging country’s political,economic,and financial instabilities are strongly associated with increasing the banking sector’s credit risk and a rise in political risk in particular has the most positive prominent impact on the banking sector of countries with a higher degree of non-performing loans(Q.25=−0.122,Q.50=−0.141,Q.75=−0.163,Q.95=−0.172).Moreover,the results suggest that,in addition to the banking sectorspecific determinants,credit risk is significantly impacted by the financial market development,lending interest rate,and global *** results are robust and have significant policy suggestions for many policymakers,bank executives,researchers,and analysts.

A Note on Submodularity Preserved Involving the Rank Functions

作者： Qirong Li Yaya Zhang faculty of business administration Shanxi University of Finance & Economics faculty of business administration Shanxi University of Finance and Economics

Aiming at the problems of unreasonable random distribution mechanism and unbalanced shelf scheduling in the operation of B smart e-commerce logistics center, this paper firstly makes reasonable allocation of intelligent moving equipment on the basis of comprehensive consideration of multiple influencing factors. Secondly, the intelligent handling robot scheduling model is established and the standard particle swarm optimization algorithm is used for analysis. Finally, by optimizing and improving the algorithm, the two-particle swarm optimization algorithm is used to solve the problem, and the conclusion is given.

Purpose - From the literature of customer experience management, the researcher found that customer experience management was a powerful company's strategy to create customer satisfaction and to maintain customer loyalty to the brand for a long term commitment. The aim of this study was to examine the influence of customer experience management components that affected customer loyalty in Thailand's Supercenters. Design/methodology/approach - Structural equation modeling was used to test the hypotheses. Findings - According to the causal model of customer experience management on customer loyalty, the study found that customer experience management components had some influences over loyalty behavior i.e. increased purchase, cross-buying, up-buying, re-buying, word-of-mouth, and share of wallet through affective experience, cognitive experience, customer satisfaction and customer loyalty are considered as the highest correlation coefficient which represented a strategy resulting in a win- win value exchange between the retailer and its customers. Originality/value - Customer experience management is significance tool for the marketing strategies of businesses to enhance customer loyalty especially in competitive environment.

This paper takes the basic mathematical operations required to manipulate the cognitive maps. This paper start by presenting all the values that a causal relationship can take. By the using of causal algebra, cognitive map (CC) become not only a graphical representation of a person’s beliefs, an agent or a particular area but also can capture the causal relationships existing between the concepts of a given system in a simple manner. Cognitive maps do not use a conventional algebra;algebra causal is needed to treat.
