Health Benefits for the Uninsured: Design and Early Implementation of the Accelerated Benefits Demonstration
Many Social Security Disability Insurance (SSDI) beneficiaries have serious and immediate health care needs, but, under current law, most are not eligible for Medicare until 24 months after they start receiving cash benefits. This policy brief describes a new project that is testing whether providing earlier access to health benefits, as well as other services, for new SSDI beneficiaries who have no other health insurance improves employment and health outcomes
Lightweight Multilingual Software Analysis
Developer preferences, language capabilities and the persistence of older
languages contribute to the trend that large software codebases are often
multilingual, that is, written in more than one computer language. While
developers can leverage monolingual software development tools to build
software components, companies are faced with the problem of managing the
resultant large, multilingual codebases to address issues with security,
efficiency, and quality metrics. The key challenge is to address the opaque
nature of the language interoperability interface: one language calling
procedures in a second (which may call a third, or even back to the first),
resulting in a potentially tangled, inefficient and insecure codebase. An
architecture is proposed for lightweight static analysis of large multilingual
codebases: the MLSA architecture. Its modular and table-oriented structure
addresses the open-ended nature of multiple languages and language
interoperability APIs. We focus here as an application on the construction of
call-graphs that capture both inter-language and intra-language calls. The
algorithms for extracting multilingual call-graphs from codebases are
presented, and several examples of multilingual software engineering analysis
are discussed. The state of the implementation and testing of MLSA is
presented, and the implications for future work are discussed.Comment: 15 page
Lightweight Call-Graph Construction for Multilingual Software Analysis
Analysis of multilingual codebases is a topic of increasing importance. In
prior work, we have proposed the MLSA (MultiLingual Software Analysis)
architecture, an approach to the lightweight analysis of multilingual
codebases, and have shown how it can be used to address the challenge of
constructing a single call graph from multilingual software with mutual calls.
This paper addresses the challenge of constructing monolingual call graphs in a
lightweight manner (consistent with the objective of MLSA) which nonetheless
yields sufficient information for resolving language interoperability calls. A
novel approach is proposed which leverages information from a
compiler-generated AST to provide the quality of call graph necessary, while
the program itself is written using an Island Grammar that parses the AST
providing the lightweight aspect necessary. Performance results are presented
for a C/C++ implementation of the approach, PAIGE (Parsing AST using Island
Grammar Call Graph Emitter) showing that despite its lightweight nature, it
outperforms Doxgen, is robust to changes in the (Clang) AST, and is not
restricted to C/C++.Comment: 10 page

Effects of Product Prototypicality on Brand Resonance in Brand Extensions
This study investigates whether differing degrees of prototypical brands and brands that are either functional or symbolic in nature can undertake brand extensions, and if so, to what degree of congruency. The research uses a factorial design of 3 (congruency) x 2 (prototypicality) x 2 (motivation) x 2 (brand type) using four real brands. The study also creates a uni-dimensional prototypicality scale which is the first to provide a Likert type measure for prototypical brands
An Analysis of Muon Neutrino Disappearance from the NuMI Beam Using an Optimal Track Fitter
Thesis (Ph.D.) - Indiana University, Physics, 2015The NOvA experiment is a long-baseline neutrino oscillation experiment based out of Fermilab National Accelerator Laboratory that uses two liquid scintillator detectors, one at Fermilab (the "near" detector) and a second 14 kton detector in northern Minnesota (the "far" detector.) The primary physics goals of the NOvA experiment are to measure neutrino mixing parameters through both the disappearance and appearance channels using neutrinos from the newly upgraded NuMI beam line. The NOvA disappearance analysis can significantly improve the world's best measurement of . This analysis proceeds by using the measured charged-current energy spectrum in the near detector to predict the spectrum in the far detector, and comparing this to the measured spectrum to obtain a best fit for the oscillation parameters and . Since this fit is governed by the shape of the energy spectrum, the best fit will be maximized by obtaining the best possible energy resolution for the individual neutrino events. This dissertation describes an alternate disappearance analysis technique for the NOvA experiment, based on the idea that estimating the energy resolution of the individual events will allow them to be separated into different energy resolution samples in order to improve the final fit. This involves using an optimal tracker to reconstruct particle tracks and momenta, and multivariate methods for estimating the event energies and energy resolutions. The data used for this analysis was taken by the NOvA experiment from February 2014 to May 2015, representing approximately protons on target from the NuMI beam. The best fit oscillation parameters obtained by this alternate technique are ~ and ~ which is consistent with the hypothesis of maximal mixing, and with the results from T2K and MINOS+ published in 2015
