    Get PDF
    The report provides an overview of financial aid types and funding sources within the University of Maine System. A change from prior year reports is the use of financial aid year for most aid types with the exception of waivers and Federal Work-Study. Fiscal year serves as the timeframe for all data prior to aid year 2014

    Evolution and Change in Civic Engagement Organizations: A Life-Cycle Analysis of the Maine League of Young Voters

    Get PDF
    The Maine League of Young Voters is an organization involved in educational and political civic engagement activities in the State of Maine. A membership base consisting of hundreds of grassroots members makes up the base of the organization. By studying the life cycle of the Maine League of Young Voters and comparing it to similar civic engagement organizations, the research here aims to increase the body of knowledge available about how these types of organizations evolve and change. Findings from surveys and interviews indicated that the organization was over-extending the membership, despite a strong grassroots network, and that more delegation of tasks and leadership is necessary. Recommendations are included for improving the ability of the organization to detect and self-assess potential difficulties in the future

    Possible liquid immiscibility textures in high-magnesia basalts from the Ventersdorp Supergroup, South Africa

    Get PDF
    The lowermost succession of lavas in the Proterozoic Ventersdorp Supergroup contains light weathering ocelli up to 15 cm in diameter which occur in layers of a darker weathering volcanic material. Some ocelli appear to merge, and discrete light weathering layers may be the ultimate end-stage of this coalescence. Alternatively, coexisting magmas in the neck of the volcano may have been erupted in varying proportions, and turbulence during flow caused spalling of large drops of the lighter weathering material into the other. Several lines of field evidence suggest that two distinct liquids coexisted and were rapidly quenched after eruption. Chemical data for ocelli and matrix are consistent with the hypothesis of liquid immiscibility. The differences in compositions between the coexisting pairs of liquids are small and it is suggested that the original magmas must have been close to the consulute composition

    Accurate Profiling of Microbial Communities from Massively Parallel Sequencing using Convex Optimization

    We describe the Microbial Community Reconstruction ({\bf MCR}) Problem, which is fundamental for microbiome analysis. In this problem, the goal is to reconstruct the identity and frequency of species comprising a microbial community, using short sequence reads from Massively Parallel Sequencing (MPS) data obtained for specified genomic regions. We formulate the problem mathematically as a convex optimization problem and provide sufficient conditions for identifiability, namely the ability to reconstruct species identity and frequency correctly when the data size (number of reads) grows to infinity. We discuss different metrics for assessing the quality of the reconstructed solution, including a novel phylogenetically-aware metric based on the Mahalanobis distance, and give upper-bounds on the reconstruction error for a finite number of reads under different metrics. We propose a scalable divide-and-conquer algorithm for the problem using convex optimization, which enables us to handle large problems (with ∼106\sim10^6 species). We show using numerical simulations that for realistic scenarios, where the microbial communities are sparse, our algorithm gives solutions with high accuracy, both in terms of obtaining accurate frequency, and in terms of species phylogenetic resolution.Comment: To appear in SPIRE 1

    Great Britain's Energy Vectors and Transmission Level Energy Storage

    Get PDF
    As an example of the challenges facing many developed countries, the scale of daily energy flows through Great Britain's electrical, gas and transport systems are presented. When this data is expressed graphically it illustrates important differences in the demand characteristics of these different vectors; these include the scale of energy delivered through the networks on a daily basis, and the scale of variability in the different demands over multiple timescales (seasonal, weekly and daily). The paper discusses energy storage in general; the scale of within day stores of energy available to the gas and electrical transmission networks, and suggests Synthetic Natural Gas as an interesting energy carrier that could use existing natural gas infrastructure
