电凝聚降氟器降氟改水的实验研究

通过对Ｚ—Ⅰ，Ｚ—Ⅱ型降氟器在沧州市饮用水降氟实验结果的对比研究，发现水的ｐＨ值、反应器的工作电流是制约降氟效果的关键。由于Ｚ—Ⅱ型降氟器对ｐＨ值具有控制作用，所以其降氟效果较好。     

矿山机电设备管理中存在的问题及解决对策

Differences in the Cost of Trade Execution Services on Floor-Based and Electronic Futures Markets

This paper provides new evidence on the impact of electronic trading on brokerage commissions by investigating a sample period that covers the period of transition from floor to electronic trading on the Sydney Futures Exchange. After controlling for liquidity, volatility and broker identity, the introduction of electronic trading remains to be associated with lower brokerage commissions relative to floor markets. The study also provides new evidence on brokerage commissions in futures markets finding that commission fees charged on futures trades average 0.002% of transaction value. This is up to 120 times smaller than the magnitude of brokerage fees charged in stock markets, and considerably lower than the magnitude of brokerage fees assumed for futures markets in previous research. Consistent with existing studies based on stock markets, commissions charged per contract decrease with order size reflecting economies of scale in the provision of brokerage services in futures markets. Commission rates are positively related to bid-ask spreads and price volatility, which proxy for the probability of execution error costs and execution difficulty, respectively. Finally, the identity of the broker is found to be a significant determinant of commissions reflecting different pricing schedules across brokers.

Technology improves sales performance—doesn't it?: An introduction to the special issue on selling and sales technology

Firms around the globe are rushing to invest in sales force technology or sales force automation (SFA). SFA appears to mean different things to different people. For example, management and sales personnel view the need for, application of, and advantages of SFA quite distinctly. As a result of technology, this special issue examines many areas of sales force automation to provide both practicing managers and sales force academicians with a clearer perspective of new technology in the B2B marketplace. This article introduces the special issue topic, individual contributors, and acknowledges support proffered by myriad individuals.     

Sales force technology usage—reasons, barriers, and support: An exploratory investigation

Increasingly, salespeople are being asked to adopt and use a variety of technologies to increase their selling productivity and efficiency, including sales force automation and customer relationship management technologies. However, little research has investigated what happens once sales force automation (SFA) technology is adopted. This paper explores the reasons why salespeople use SFA technologies, the perceived barriers to SFA usage and how management can increase the usage of SFA technology. First, a qualitative study was performed to gain insight about salespeople's automation technology usage and the reasons why some salespeople fully use or do not utilize technology. After the initial study, 130 salespeople were surveyed. More productivity/efficiency was the main reason why salespeople use technology, the lack of management and technical support proved to be the main barrier to usage, and training proved most effective in increasing usage of SFA technology. Sales managers are provided with implications of the findings.
