Behavioral and Morphological Development of Immature Hawaiian Freshwater Fishes.

Studies of recent fish collections from 17 streams on four islands in Hawai\u27i provided key characteristics for species identification of immature forms of five native species of freshwater gobioids. Young Eleotris sandwicensis lack fused pelvic fins. A suborbital bar identifies Stenogobius hawaiiensis. Awaous guamensis can be distinguished by lack of notches in the upper lip, Lentipes concolor by a single median notch, and Sicyopterus stimpsoni by three notches. Recruitment from oceanic plankton occurred year round but peaked from February to April. Lentipes invaded streams mainly during the day with the wave surge; Sicyopterus entered mostly during the day regardless of tidal conditions. Awaous were transported onshore day or night. Stenogobius and Eleotris entered streams by passive transport, the former by day, the latter at night. Eleotris and Stenogobius larvae mature in the lower stream reaches while Lentipes, Sicyopterus, and Awaous usually move to upstream habitats. For these latter three fishes, ontogenetic changes in behavior, including predator avoidance during recruitment and aggressive interactions between immature fishes farther upstream, act in sequence to produce the instream distribution typical of adults. Schooling occurred in the estuary in Sicyopterus and Awaous postlarvae; singles and pairs also migrated into streams. Postlarvae remained in schools through the estuary where they were vulnerable to predation by adult Eleotris and Kuhlia sandvicensis. After climbing a waterfall that excluded most aquatic predators, Awaous and Sicyopterus developed coloration displayed during aggressive contests. Immature Sicyopterus that failed to develop bright colors lost agonistic encounters and usually fled upstream. Aggressive displays by postlarval Awaous usually displaced intruders. Lentipes moved quickly upstream; they did not school but exhibited aggressive behavior toward conspecifics that promoted upstream dispersal. Techniques and baseline data from this study were used in assessing recovery of three Kaua\u27i streams damaged by Hurricane Iniki (11 September, 1992)

Full Isolation Number of Matrices: Some Extremal Results

A set of nonzero entries of a (0,1)-matrix is an isolated set if no two entries belong to the same row, no two entries belong to the same column, and no two entries belong to a submatrix of the form [1 1; 1 1]. The isolation number of a matrix is the maximum size over all isolated sets. The isolation number of a matrix is a well-known and well-used lower bound for the matrix\u27s Boolean rank. We will discuss the isolation number of the adjacency matrix of various graphs and develop some extremal results for n x n matrices with isolation number n

ICT, the Changing Line of Visibility, and Customer Impressions of Organisational Competencies

This paper describes a study using mystery shoppers across multiple channels which investigated the traditional ‘line of visibility’ from service quality literature, and customer perceptions of organisational competencies “below the line”. We posited that in a multi-channel e-commerce environment, inconsistency or service breakdown above the line of visibility gives a negative impression of organisational competence below the line. We found that our multi-channel customers, using a mixture of face-to-face and ICT (information communication technology) channels, formed positive and negative impressions of a range of organisational competencies, and made comparisons between the service levels provided across different channels. We also found that ICT-mediated channels can create an emotional connection with customers; customers prefer to have a choice as to whether to use self-service channels or not; and that customers expect staff members to be empowered not restricted by ICTs

Acquisition Challenges of Autonomous Systems

The Department of Defense has stated publicly that future defense capabilities will depend strongly on autonomous systems;systems that make sophisticated judgments about the world and choose appropriate courses of action, and perhaps even adapt and learn over time. Developing and deploying such systems poses more than just a technical challenge in robotics and artificial intelligence;it also poses many challenges to the acquisition process and workforce. From cost estimation to sustainment planning, every aspect of acquisition will be affected. Test and evaluation, in particular, may require not only novel methodologies and resources, but organizational and process changes as well.Naval Postgraduate School Acquisition Research Progra

CoAKTinG: Collaborative Advanced Knowledge Technologies in the Grid

Grid infrastructures coupled with semantic web linkage and reasoning open up intriguing new possibilities for scientific collaboration. In this short paper, we outline the research agenda and collaboration technologies under development within the CoAKTinG project: Collaborative Advanced Knowledge Technologies in the Grid. CoAKTinG will provide tools to assist scientific collaboration by integrating intelligent meeting spaces, ontologically annotated media streams from online meetings, decision rationale and group memory capture, meeting facilitation, issue handling, planning and coordination support, constraint satisfaction, and instant messaging/presence. Their integration is illustrated through an extended use scenario
