9515434 Skvoretz The proposed research is a cooperative effort between researchers at the University of Carolina (John Skvoretz and David Willer) and the University of Iowa (Michael Lovaglia and Barry Markovsky). This work extends a program of theory-based investigations on power and social exchange processes. Network Exchange Theory (NET) is one of several theories that attempt to explain the development of power in networks of exchange relations. While previous research has demonstrated that NET predictions are more accurate than its competitors, a problem recently surfaced in a fundamental part of the theory that classifies networks as strong or weak power, the Graph-theoretical Power Index (GPI). In solving this problem, two independent methods of predicting power relations in exchange networks were developed by the investigators. This set the stage for a dramatic improvement in the sped and quality of exchange research. By developing integrated computer programs, the investigators proposed to automate the systematic construction, comparison and classification of exchange networks. Networks for which the two methods disagree can be culled from further analysis from thousands of potential test networks. This will then enable the PIs to make exact predictions for resource distribution in these networks and compare them to computer simulations. The entire process of discovering problematic test networks and preparing them for experimental test can be accomplished in a matter of hours, whereas previously, suitable test networks were discovered largely by chance and the process could take years. Then the PIs propose to improve experimental methods and statistical techniques to investigate a number of networks that were crucial in the solution to the classification problem. These advances will bring us a step closer to modeling exchange processes in complex networks commonly found in society. ***

9515434 Skvoretz提出的研究是卡罗来纳大学（John Skvoretz和David Willer）和爱荷华大学（Michael Lovaglia和Barry Markovsky）的研究人员之间的合作努力。 这项工作扩展了有关权力和社会交流过程的基于理论的调查计划。 网络交换理论（NET）是尝试解释交换关系网络中权力发展的几种理论之一。 尽管以前的研究表明，净预测比其竞争对手更准确，但最近在理论的基本部分中浮出水面，将网络归类为强或弱幂，但图理论功率指数（GPI）。 在解决此问题时，研究人员开发了两种预测交换网络中电力关系的独立方法。 这为交流研究的SPED和质量做出了巨大改善奠定了基础。 通过开发集成的计算机程序，调查人员提议自动化交换网络的系统构建，比较和分类。可以从数千个潜在的测试网络中进一步分析这两种方法不同意这两种方法的网络。 然后，这将使PI能够对这些网络中的资源分布做出确切的预测，并将其与计算机模拟进行比较。 发现有问题的测试网络并为实验测试做准备的整个过程可以在几个小时内完成，而以前，合适的测试网络是偶然发现的，并且该过程可能需要数年。 然后，PI提议改善实验方法和统计技术，以研究对解决分类问题至关重要的许多网络。 这些进步将使我们更接近建模社会中常见的复杂网络中的交换过程。 ***
