基于组合双向拍卖的云资源调度方法

针对跨数据中心的资源调度问题，提出了一种基于组合双向拍卖（PCDA）的资源调度方案。首先，将云资源拍卖分为三个部分：云用户代理报价、云资源提供商要价、拍卖代理组织拍卖；其次，在定义用户的优先级及任务紧迫度的基础上，在拍卖过程中估算每一个工作发生的服务等级协议（SLA）违规并以此计算云提供商的收益，同时每轮竞拍允许成交多项交易；最终达到根据用户等级合理分配云资源调度的效果。仿真实验结果表明该算法保证了竞拍成功率，与传统一次拍卖成交一项的组合双向拍卖方案相比，PCDA在竞拍时间段产生的能耗降低了35.00%，拍卖云提供商的利润提高了约38.84%。

一种非对称互联型粒子群算法

提出了一种非对称互联型粒子群算法(AFIPSO),它是对互联型粒子群算法的改进。此算法重新构造了加权函数,体现了粒子之间的非对称影响。随后对六种加权函数及其4种交叉组合进行了测试。试验结果表明:组合加权函数对算法的收敛速度和稳定性均有非常好的改善,在收敛率上几近完美。

Introduction to the special section on racial and ethnic identity in counseling psychology: Conceptual and methodological challenges and proposed solutions.

Racial and ethnic identity development have been important topics in counseling psychology research for the last four decades. At present, however, there appears to be some confusion and debate regarding the quality of theory and measurement in the topical area. The present article serves as an introduction to this Journal of Counseling Psychology special section on "Racial and Ethnic Identity in Counseling Psychology: Conceptual and Methodological Challenges and Proposed Solutions." A rationale is provided for the special section, the place of racial and ethnic identity scholarship is located within the history of multicultural counseling research, and the invited special section contributions by K. O. Cokley (2007), J. E. Helms (2007), J. E. Trimble (2007), S. M. Quintana (2007), J. S. Phinney and A. D. Ong (2007), and J. G. Ponterotto and J. Park-Taylor (2007) are introduced.

Integrating psychology and politics.

Comments on the article "A house divided? The psychology of red and blue America" by D. C. Seyle and M. L. Newman (see record 2006-11202-001). Seyle and Newman concluded that the red and blue metaphor is inaccurate and proposed a purple America strategy to better convey that the majority of people do not align themselves with political extremes. There is interdisciplinary agreement on this. Although not cited by Seyle and Newman, the findings by Professor Fiorina of Stanford University were reported by the APA Monitor on Psychology in its coverage of the 2005 APA State Leadership Conference (Murray Law, 2005). In contrast to their social psychological analysis, Seyle and Newman were incorrect in concluding that "[a]s psychologists, we are not in a position to change either the elements of the American political system that may spur this conflict or even the decisions made by pundits, politicians, and reporters about the terms they choose to use in political discussion" (p. 579).

The Israeli-Palestinian peace process and its vicissitudes: Insights from attitude theory.

The vicissitudes of the Israeli-Palestinian peace process since 1967 are analyzed using attitudes and related concepts where relevant. The 1967 war returned the two peoples' zero-sum conflict around national identity to its origin as a conflict within the land both peoples claim. Gradually, new attitudes evolved regarding the necessity and possibility of negotiations toward a two-state solution based on mutual recognition, which became the building stones of the 1993 Oslo agreement. Lacking a commitment to a final outcome, the Oslo-based peace process was hampered by reserve options, which increased avoidance at the expense of approach tendencies as the parties moved toward a final agreement. The resulting breakdown of the process in 2000 produced clashing narratives, reflecting different anchors for judgment and classical mirror images. Public support for violence increased, even as public opinion continued to favor a negotiated two-state solution. Reviving the peace process requires mutual reassurance about the availability of a partner for negotiating a principled peace based on a historic compromise that meets the basic needs and validates the identities of both peoples.
