Cultivating Community: The role of the Winooski school system in creating positive relationships between city institutions and the refugee population
Schools serve as key institutions for absorbing newcomers into American society, as they provide resources, programming, and access points into a community for immigrant children and their families. In Winooski, Vermont, the public school building serves as a center for support and engagement for the refugee population, offering a variety of services to children and their parents. As demographics shift to include more foreign-born students, schools need to rethink classroom strategies and ways of engaging with families that best navigate cultural divides. My findings suggest that Winooski can be viewed as a model city for bridging the cultural divides inherent in refugee resettlement: various community institutions, in collaboration with the school system, provide services and support for refugee families, and the school serves as a center for support and community engagement. These processes can be examined through the social network concept of multiplexity. Put simply, community members know and trust each other in several different roles, increasing the capacity of the community to support one another and generate trust. At the center of this social network are the multicultural liaisons, who play a critical role in supporting refugees in communities, and enhance this network of trust. The research presented here highlights the unique processes in place that make Winooski a successful site for refugee resettlement, and recognizes the work of those in the community that dedicate themselves to increasing the level of acceptance and cultural understanding throughout the district and the community as a whole
Suitability of using technical indicators as potential strategies within intelligent trading systems
The potential of machine learning to automate and control nonlinear, complex
systems is well established. These same techniques have always presented
potential for use in the investment arena, specifically for the managing of
equity portfolios. In this paper, the opportunity for such exploitation is
investigated through analysis of potential simple trading strategies that can
then be meshed together for the machine learning system to switch between. It
is the eligibility of these strategies that is being investigated in this
paper, rather than application. In order to accomplish this, the underlying
assumptions of each trading system are explored, and data is created in order
to evaluate the efficacy of these systems when trading on data with the
underlying patterns that they expect. The strategies are tested against a
buy-and-hold strategy to determine if the act of trading has actually produced
any worthwhile results, or are simply facets of the underlying prices. These
results are then used to produce targeted returns based upon either a desired
return or a desired risk, as both are required within the portfolio-management
industry. Results show a very viable opportunity for exploitation within the
aforementioned industry, with the Strategies performing well within their
narrow assumptions, and the intelligent system combining them to perform
without assumptions.Comment: Paper Presented at the 2011 IEEE International Conference on Systems,

Influence of excess diamine on properties of PMR polyimide resins and composites
By varying the stoichiometry of the reactants in the preparation of PMR polyimide resin, changes occur in molecular weight distribution which influence the rheological properties and thus the processability of the resin, as well as the mechanical properties of the composite. The influence of 1-10 percent molar excess MDA on the molecular weight distribution and rheological properties of an imidized PMR system were exposed. Molecular weight distribution is characterized by gel permeation chromatography of the imidized molding compound; shear viscosity is related to changes in average molecular weight. The thermo-oxidative stability at 600 F, glass transition temperature, flexural and interlaminar shear properties of PMR polyimide/Celion 6000 graphite fiber composites are compared as a function of the percent excess MDA in the monomer reactant mixture
Ceramic matrix and resin matrix composites: A comparison
The underlying theory of continuous fiber reinforcement of ceramic matrix and resin matrix composites, their fabrication, microstructure, physical and mechanical properties are contrasted. The growing use of organometallic polymers as precursors to ceramic matrices is discussed as a means of providing low temperature processing capability without the fiber degradation encountered with more conventional ceramic processing techniques. Examples of ceramic matrix composites derived from particulate-filled, high char yield polymers and silsesquioxane precursors are provided
New capacities and modifications for NASTRAN level 17.5 at DTNSRDC
Since 1970 DTNSRDC has been modifying NASTRAN to suite various Navy requirements. These modifications include capabilities as well as user conveniences and error corrections. The new features added to NASTRAN Level 17.5 are described. The subject areas of the additions include magnetostatics, piezoelectricity, fluid structure interactions, isoparametric finite elements, and shock design for shipboard equipment
