In this paper we sought to evaluate the implementation of the Water Exploration Legacy Cycle, a research collaborative project developed by the Institute for Geophysics at The University of Texas at Austin and 4empowerment.com with support from the Texas Water Development Board. This project interviewed six teachers of the 22 science educators who attended a workshop to learn about the Legacy Cycle approach and how to implement the Water Exploration Legacy Cycle curriculum in August of 2010. The research involved a survey and a phone interview, both of which collected data on the training session, the teachers’ abilities to work with the Legacy Cycle within their curriculum, and obstacles they faced with full implementation of the program. Recommendations from this study will aid future developers in creating Legacy Cycle modules that are better adapted to high school classrooms. / text

The Paleoproterozoic Talbot volcanogenic massive sulphide (VMS) Cu-Zn occurrence is located near Talbot Lake, Manitoba, about 80 km south of Snow Lake. The mineralised system is unconformably overlain by more than 100 m of Paleozoic dolomite sequences and Quaternary glacial till. The clay fraction of the till contains pronounced anomalies of Zn, Cu, Ag, Pb, Au, Mn, Hg, Cd, Co, Bi and Se, which is ascribed to the formation of clay-humic complexes that have carbon-isotopic compositions of δ13C < -20‰. A VMS origin of the near-surface anomaly is confirmed by distinctly low 206Pb/204Pb ratios, compared to a more radiogenic till signature. The overall low 206Pb/204Pb ratios in the organic surface media black spruce bark, moss and humus also indicate input from a magmatic sulphide source, but likely reflect windblown material from the Flin Flon smelter stack at 160 km to the northwest. Black spruce tree rings that pre-date industrial sources of atmospheric metal input are used to measure historical element distributions because they record the local geochemistry at the time of heartwood growth and their root systems tap into large volumes of soil. At the Talbot prospect, the presence of secondary Zn from the till in black spruce tree cores is reflected in the Zn/Ca ratio, which eliminates the effect of dolomite-derived Zn. The process of element migration from buried mineralisation to the surface is complex and includes oxidation of sulphides, mobilisation and complexation of metal ions, physical upward transport, and deposition of indicator elements near the surface in accessible sampling media. To account for a significant influx of indicator elements into the relatively recently deposited till blanket, post-glacial groundwater upwelling is proposed to act as a major mechanism driving upward element migration. / Thesis (Ph.D, Geological Sciences & Geological Engineering) -- Queen's University, 2011-05-14 04:38:36.886

Drawing on studies of strategic dynamics and organizational change, this thesis proposes four approaches to balancing exploration and exploitation over time: Specialist, Cyclical, Irregular, and Regular. Various approaches to ambidexterity may be more effective under different environment conditions, and performance may vary along with: 1) varying types of rule change environments, 2) varying levels of competitive intensity among firms, 3) reactive versus proactive timing heuristics, and 4) varying levels of product diversification. Several hypotheses are developed and confirmed using qualitative field research and agent-based modeling. Results indicated that strategic leaders should balance their exploration and exploitation with Regular ambidexterity as their environments become dominated by competence enhancing innovation. Conversely, firms should temporally shift their balance of exploration and exploitation when competence-destroying changes dominate. In a balanced environment, Irregular ambidexterity performs best. These finding are especially relevant in highly competitive contexts. Also, proactive switching increases performance more than reactive switching, whereas diversification reduces the performance of sequential heuristics.

Vad händer om de ständiga förbättringarna tar slut? Förmågan att ständigt utvecklas och förändras har i vårt samhälle och inom den svenska industrin blivit en allt viktigare konkurrensfördel för att skapa framgångsrika organisationer. Marknadsförändringar förekommer numera i en alltmer progressiv takt och det framstår att organisationer med ett gott kreativt klimat förmår att skapa goda förutsättningar för att hantera omvärldens föränderlighet. Kärnan för industriella organisationer är ytterst att upprätthålla en accepterad produktionstakt och samtidigt skapa ett kreativt klimat som ger goda förutsättningar för att utveckling kan frodas. Det råder en enighet om att organisationer med ett gott kreativt klimat som ger medarbetare stöd, möjlighet och utrymme att omsätta idéer till verklig nytta, skapar goda förutsättningar för organisationers utvecklingsförmåga. Lösningen blir således organisationers interna kreativa klimat och hur förutsättningar för att förhålla sig utvecklingsorienterad skapas, i en alltmer föränderlig miljö, med en tro på den enskilda medarbetares förmåga att ständigt utvecklas. Organisationer har således mycket att vinna på att förstå och kontinuerligt mäta skillnaden mellan det rådande kreativa klimatet och det eftertraktade klimatet. Syftet med den här fallstudien är att mäta en svensk industris kreativa klimat och undersöka vilka hinder och möjligheter organisationens ledare och medarbetare upplever i utvecklingsarbetet.  Ett sekundärt syfte är att bidra till en ökad förståelse av förutsättningarna för en utvecklingsorienterad organisation i en industriell kontext genom att undersöka, utvärdera och analysera komplexiteten av utvecklingsarbetet. Studien visar en diskrepans i det kreativa klimatet mellan organisationens befintliga avdelningar och uppmuntrar till ytterligare forskning för att åskådliggöra de kausala relationerna.

The Global Positioning System (GPS) is a satellite navigation system which, when fully operational, "will provide highly accurate position and velocity information in three dimensions, as well as precise time, to users around the globe 24 hours a day" (Anon, 1990). GPS can be operated under all weather conditions, with the only restriction being that the user must be able to receive radio signals from the satellites. Such a comprehensive positioning system has never been previously available, and thus GPS is currently being used for a diverse range of applications. This thesis is focused at the application of GPS for the offshore oil industry which is requiring increasingly higher instantaneous positioning accuracies. The GPS system and real-time positioning techniques are described, along with the main error sources that limit the available accuracy. The suitability of using GPS observations in a standard set of mathematical algorithms, the Kalman filter, in order to obtain position and velocity information has been examined. This is carried out by analysing the observations in order to determine some statistical properties that are usually ignored during the processing and data spanning a two year period has been analysed. The effect that these properties have on the resultant position and its precision was ascertained, finding that position discrepancies were insignificant but their associated precisions were highly dependent on the statistical properties were highly dependent of the data sets. Along similar lines., the ability of the Kalman filter to detect blunders, or gross errors, within GPS-type observations was analysed showing that the relevant test statistics performed sub-optimally and, again, this was dependent on the properties of the data.
