How well do conservation auctions perform in achieving landscape‐level outcomes? A comparison of auction formats and bid selection criteria

This paper studies the performance of auction design features regarding pricing mechanisms and bid selection criteria for securing wildlife zones across different holdings. We compare two pricing mechanisms: a discriminatory‐price auction and a uniform‐price ascending auction, and four bid selection criteria on the basis of: total bid, bid‐per‐value ratio, bid‐per‐area ratio and a mixed criterion where bids are formed on the basis of cost but they are selected based on the bid‐per‐value ratio. We develop a best‐response group‐bidding model for a discriminatory‐price auction where bidders form optimal group bids for individual wildlife zones. In the uniform‐price ascending auction, individual landholders respond to prices, which are successively raised by the auctioneer and whenever all the landholders from a single zone agree to participate (i.e. the first zone is formed), the auction stops. Based on numerical simulations using a bio‐economic model of malleefowl conservation, we observe that the discriminatory‐price auction is more cost‐effective than the uniform‐price ascending auction. However, the budgetary cost‐effectiveness of a discriminatory‐price auction is sensitive to bidder uncertainty about the number of competing bidder groups and the highest cost of establishing a wildlife zone among these groups. In terms of bid selection, the mixed bid selection criterion performs best. We discuss the policy implications of these findings.     

我国化肥价格波动与农民收入关系的实证分析

本文利用1978～2008年的时间序列数据,运用脉冲响应函数和方差分解技术考察化肥价格波动与农民收入之间的关系,发现化肥价格的波动与农民收入变化之间存在着双向的因果关系,即化肥价格的上涨导致农民增收缓慢,而化肥价格上涨的根本原因在于＂需求拉动＂和＂成本推动＂。今后必须从需求和供给两方面采取对策：一方面通过建立化肥直接补贴制度和化肥储备制度,从需求上控制化肥价格上涨;另一方面通过采用新型化肥生产技术和给予化肥生产企业生产用能以优惠政策,从供给上控制化肥价格上涨。     

松动爆破在突出煤层巷道掘进中的实践与应用

煤层突出危险一直是影响矿井煤巷安全快速掘进的重要因素,传统的防治方法又严重制约掘进面的生产速度。以五轮山矿井8#突出煤层1801运输顺槽为例,提出在区域消突前提下采用松动爆破方法实现快速掘进。实践证明,中深孔松动爆破治理瓦斯,较好地解决了煤巷掘进过程中掘进速度与防治瓦斯之间的矛盾,实现了煤巷的安全快速掘进,具有较好的经济效益,可以为煤矿的防突工作提供借鉴。     

集团化办学：一种职业教育集群价值链增值模式的选择

企业集群理论是从价值增值环节研究经济组织和资源配置的管理学理论,企业集群的互利机理与共生机制对指导职业教育集团的发展有着重要的意义。文章结合我国职业教育和职教集团的现状,提出集团化办学是一种职业教育集群升级模式。职教集群升级本质上是集群治理效率的提升。我国职教集团化办学大体处于短距离市场价值链层级,要实现价值链的高移与升级,必须加快从短距离市场价值链到准等级型价值链的演进和从准等级型价值链到网络型价值链的提升。而要实现这种升级,必须基于深度产学合作和资源整合实现职业集团角色转型和准确定位,以实现职业教育与区域经济的良性互动与对接。

The Effectiveness of a Buzz Marketing Approach Compared to Traditional Advertising: An Exploration

Marketers are now willing to go anyplace they can find a captive audience to espouse the virtues of their products. The success of the “buzz” marketing approach is linked to the consumer being lured into doing the advertising by spreading the message to others. This study compares students’ responses to a traditional advertising and a buzz approach. Using a factor analysis to identify variables, the results show that subjects perceive a buzz approach to be more influential than a traditional advertising. However, they do not perceive a buzz approach to be authentic. This finding is consistent with practitioners’ argument that, although a buzz approach may be effective in the short-term, once consumers recognize its selling intent, the program may have a “boomerang effect.”     

Perceptions of facilitators of a keypad‐based group support system

Organizations are using Group Support Systems (GSSs) to improve the quality of group meetings. Keypad‐based GSSs are a widely used form of this technology, yet there has been little research on their use and effects. This paper reports the findings of a survey of facilitators of a particular keypad GSS. Facilitators indicate that keypad technology improves the quality of meetings for a variety of tasks in a range of group settings and cultures. The findings are in general agreement with field studies of workstation‐based systems.
