First Annual Marine Monitoring Programme Report September 2005

This report provides an overview of the development of the Marine Monitoring Programme, a description of each component of the programme, an overview of the current status of the components of the programme and an outline of the implementation of the programme as at June 2005. This report is GBRMPA’s inaugural report for the Marine Monitoring Programme. The structure of this report will form the basis of Annual Reports from the GBRMPA for the life of the Reef Water Quality Protection Plan Marine Monitoring Programme

Query Expansion for Survey Question Retrieval in the Social Sciences

In recent years, the importance of research data and the need to archive and to share it in the scientific community have increased enormously. This introduces a whole new set of challenges for digital libraries. In the social sciences typical research data sets consist of surveys and questionnaires. In this paper we focus on the use case of social science survey question reuse and on mechanisms to support users in the query formulation for data sets. We describe and evaluate thesaurus- and co-occurrence-based approaches for query expansion to improve retrieval quality in digital libraries and research data archives. The challenge here is to translate the information need and the underlying sociological phenomena into proper queries. As we can show retrieval quality can be improved by adding related terms to the queries. In a direct comparison automatically expanded queries using extracted co-occurring terms can provide better results than queries manually reformulated by a domain expert and better results than a keyword-based BM25 baseline.Comment: to appear in Proceedings of 19th International Conference on Theory and Practice of Digital Libraries 2015 (TPDL 2015

Biological and chemical oceanographic measurements in Far Northern Great Barrier Reef - February 1990

This report presents and sununarises the results of biological and chemical oceanographic sampling carried out in the far northern Great Barrier Reef during February 1990. The region sampled (ca. 11-13°S), lies adjacent to the eastern side of Cape York Peninsula, locations on which are under consideration for national park declaration, the construction of a rocket launching facility and silica sand mining. As little is known regarding the biological and chemical oceanography of the region, a reconnaissance survey was carried out to obtain baseline data on hydrographic, nutrient and sediment characteristics of shelf waters and sediments. It is expected that the data presented herein will form part of the environmental assessment for development in, and conservation of, the region and serve as a basis for designing more detailed and focused water quality surveys

Dissolved and particulate nutrients in waters of the Whitsunday Island Group 1988

This report summarizes the results of hydrographic sampling of physical properties and nutrient determinations made on water samples and water column particulate matter collected in February. 1988 during an oceanographic survey through the Whitsunday Island group. The survey was carried out to obtain background data on concentrations of chlorophyll, organic and inorganic nitrogen (N). phosphorus (P), and inorganic silicate (Si) in waters of the Whitsunday Island group. For comparative purposes, hydrographic and nutrient data from ten stations occupied in inter-reefal and lagoonal waters of the central and southern GBR during January. 1987 and February, 1988 are also presented

Effects of hyperlinks on navigation in virtual environments

Hyperlinks introduce discontinuities of movement to 3-D virtual environments (VEs). Nine independent attributes of hyperlinks are defined and their likely effects on navigation in VEs are discussed. Four experiments are described in which participants repeatedly navigated VEs that were either conventional (i.e. obeyed the laws of Euclidean space), or contained hyperlinks. Participants learned spatial knowledge slowly in both types of environment, echoing the findings of previous studies that used conventional VEs. The detrimental effects on participants' spatial knowledge of using hyperlinks for movement were reduced when a time-delay was introduced, but participants still developed less accurate knowledge than they did in the conventional VEs. Visual continuity had a greater influence on participants' rate of learning than continuity of movement, and participants were able to exploit hyperlinks that connected together disparate regions of a VE to reduce travel time

Systems, interactions and macrotheory

A significant proportion of early HCI research was guided by one very clear vision: that the existing theory base in psychology and cognitive science could be developed to yield engineering tools for use in the interdisciplinary context of HCI design. While interface technologies and heuristic methods for behavioral evaluation have rapidly advanced in both capability and breadth of application, progress toward deeper theory has been modest, and some now believe it to be unnecessary. A case is presented for developing new forms of theory, based around generic “systems of interactors.” An overlapping, layered structure of macro- and microtheories could then serve an explanatory role, and could also bind together contributions from the different disciplines. Novel routes to formalizing and applying such theories provide a host of interesting and tractable problems for future basic research in HCI

Conclave: ontology-driven measurement of semantic relatedness between source code elements and problem domain concepts

Software maintainers are often challenged with source code changes to improve software systems, or eliminate defects, in unfamiliar programs. To undertake these tasks a sufficient understanding of the system (or at least a small part of it) is required. One of the most time consuming tasks of this process is locating which parts of the code are responsible for some key functionality or feature. Feature (or concept) location techniques address this problem. This paper introduces Conclave, an environment for software analysis, and in particular the Conclave-Mapper tool that provides a feature location facility. This tool explores natural language terms used in programs (e.g. function and variable names), and using textual analysis and a collection of Natural Language Processing techniques, computes synonymous sets of terms. These sets are used to score relatedness between program elements, and search queries or problem domain concepts, producing sorted ranks of program elements that address the search criteria, or concepts. An empirical study is also discussed to evaluate the underlying feature location technique.info:eu-repo/semantics/publishedVersio
