Bioinvasions: Breaching Natural Barriers

This Washington Sea Grant print publication, now posted on the web, is a good introduction to the history and science of bioinvasions. Provides definitions of native and non-native organisms, identifies introduced species, the pathways and characteristics of bioinvasions, and the habitat alterations that facilitate them. Case studies include the zebra mussel and green crab. Offers suggestions for how individuals can help and describes policy responses to aquatic introductions. Downloadable as a PDF file.

Communicating You Are Worth It in a Noisy Marketplace

This paper provides guidance and specific examples of common elements needed for communicating the value proposition of liberal arts colleges to prospective students and families. In an environment where the worth of a college degree is questioned daily by the public and the mainstream media, this paper demonstrates how strategies that are distinctive, rooted in research and complementary to the institutional brand are imperative for communicating the worth of an institution. The paper suggests tactics to develop the key partnerships needed and provides metrics for how leaders can assess their value proposition initiatives

Communications

The communications sector of an economy comprises a range of technologies, physical media, and institutions/rules that facilitate the storage of information through means other than a society\u27s oral tradition and the transmission of that information over distances beyond the normal reach of human conversation. This chapter provides data on the historical evolution of a disparate range of industries and institutions contributing to the movement and storage of information in the United States over the past two centuries. These include the U.S. Postal Service, the newspaper industry, book publishing, the telegraph, wired and cellular telephone service, radio and television, and the Internet

Learning in Unlabelled Networks – An Active Learning and Inference Approach

The task of determining labels of all network nodes based on the knowledge about network structure and labels of some training subset of nodes is called the within-network classification. It may happen that none of the labels of the nodes is known and additionally there is no information about number of classes to which nodes can be assigned. In such a case a subset of nodes has to be selected for initial label acquisition. The question that arises is: "labels of which nodes should be collected and used for learning in order to provide the best classification accuracy for the whole network?". Active learning and inference is a practical framework to study this problem. A set of methods for active learning and inference for within network classification is proposed and validated. The utility score calculation for each node based on network structure is the first step in the process. The scores enable to rank the nodes. Based on the ranking, a set of nodes, for which the labels are acquired, is selected (e.g. by taking top or bottom N from the ranking). The new measure-neighbour methods proposed in the paper suggest not obtaining labels of nodes from the ranking but rather acquiring labels of their neighbours. The paper examines 29 distinct formulations of utility score and selection methods reporting their impact on the results of two collective classification algorithms: Iterative Classification Algorithm and Loopy Belief Propagation. We advocate that the accuracy of presented methods depends on the structural properties of the examined network. We claim that measure-neighbour methods will work better than the regular methods for networks with higher clustering coefficient and worse than regular methods for networks with low clustering coefficient. According to our hypothesis, based on clustering coefficient we are able to recommend appropriate active learning and inference method
