New Year\u27s Come

Why chime the bells so merrilyWhy seem ye all so gay?Is it because the New Year\u27s comeAnd the old has pass\u27d away?Oh! Can ye look upon the pastAnd feel no sorrow nowThat thus ye sing so joyouslyAnd smiles light ev\u27ry brow?Oh! If ye can be blithe and gayThe song, troul gaily onAnd the burden be the New Year\u27s come and the Old Year\u27s gone. And the burden be the New Year\u27s come and the Old Year\u27s gone. The old man gazes on your mirthHe smiles not like the restHe sits in silence by the hearthAnd seems with grief oppress\u27dHe sees not in the merry throngThe child who was his prideHe listens for her joyous songShe is not by his side!But scarce a twelvemonth she was thereAnd now he is aloneYet still ye sing the New Year\u27s come and the Old Year\u27s gone. Yet still ye sing the New Year\u27s come and the Old Year\u27s gone. Dance on! dance on! be blithe and gayNor pause to think the whileThat ere this year has pass\u27d awayYe to may cease to smileFor time in his resistless flightBrings changes sad and drearThe sunny hopes of youth to blightWith ev\u27ry coming yearBut still be happy while ye mayAnd let the dance go onStill gaily sing the New Year\u27s come and the Old Year\u27s gone!Still gaily sing the New Year\u27s come and the Old Year\u27s gone

Thermoplasmonics: Quantifying plasmonic heating in single nanowires

Plasmonic absorption of light can lead to significant local heating in metallic nanostructures, an effect that defines the sub-field of thermoplasmonics and has been leveraged in diverse applications from biomedical technology to optoelectronics. Quantitatively characterizing the resulting local temperature increase can be very challenging in isolated nanostructures. By measuring the optically-induced change in resistance of metal nanowires with a transverse plasmon mode, we quantitatively determine the temperature increase in single nanostructures, with the dependence on incident polarization clearly revealing the plasmonic heating mechanism. Computational modeling explains the resonant and nonresonant contributions to the optical heating and the dominant pathways for thermal transport. These results, obtained by combining electronic and optical measurements, place a bound on the role of optical heating in prior experiments, and suggest design guidelines for engineered structures meant to leverage such effects.Comment: 17 pages, 4 figures + 3 pages supporting materia

Partnerships and Collaboration: Working Together to Build and Achieve Disaster Recovery

On May 22, 2011, an EF-5 tornado struck Joplin, Missouri, leaving behind 161 fatalities and $2.8 billion in economic impacts. This case study research design used in-depth semi-structured, one-on-one interviews and a qualitative design and analysis to examine the economic recovery following the disaster. It also formed the foundation for future research on the impact of interdisciplinary teams, specifically disaster emergency management and social work in disaster recovery

High School Completion Categories and Post-High School Plans as Predictors of GED Certificate Attainment in a Virginia Alternative Education Program

AbstractA state-wide Individual Student Alternative Education Plan (ISAEP) seeks to assist high school (HS) students at risk of not graduating in completing HS credentials. The problem was that there was no formal state-wide process for monitoring the program to understand its impact. The purpose of this quantitative exploratory study was to determine whether the graduation variables that were published by the state could be used to predict ISAEP GED attainment. The Theory of Action proposed by McPartland and Jordan guided two main research questions to see if ISAEP GED attainment could be predicted by categories of HS completion, and if ISAEP GED attainment could be predicted by students’ post-HS plans. An archived convenience sample of ISAEP (N =131) and non-ISAEP (N = 171) schools was downloaded from a public-access database provided by the state. A weighted least squares regression (WLSR) revealed that two of the six graduation categories; Standard Diplomas and Advanced Studies Diplomas, significantly predicted ISAEP GED attainment, F(2, 86) = 10.934, p \u3c .001, with Advanced Studies being negatively related. A second WLSR was significant with two of the six post-high school plan variables. Other Continuing Education and Military Service predicted ISAEP GED, F(3, 85) = 7.614, p \u3c .001 better than the mean model alone. Because other variables are collected at the school level and not made available in the public database, it was recommended that a data committee be formed to study alternative variables that could be published by the state to improve the fidelity of future studies and the ability to continue adding to the understanding of how the ISAEP is related to student achievement. Positive social change is achieved when alternative education programs result in greater student success

Explorations of computer-based design tools for urban design projects

Thesis (M.S.)--Massachusetts Institute of Technology, Dept. of Architecture, 1992.Includes bibliographical references (leaves 117-118).This thesis is an investigation into issues involving computers, information, and automation in the designing of large-scale environments. It is an attempt to understand the issues at root in developing an "intelligent" design environment which provides tools for handling tasks often too mundane and distracting for sustained design activity. In the process of devising these tools, fundamental issues regarding the elements or objects of design, their characteristics, and the transformations they undergo are revealed in light of the particular capabilities of the computer. This study was undertaken as an attempt to discover these issues for myself by working to create a system of tools on top of an existing computer-aided design program - a personalized design environment. The path of discovery taken is reconstructed in this paper, in part to illustrate some of the pitfalls of dealing with real-world programming tasks, and also to demonstrate the revelation of the inherent issues that are involved when attempting such a project. Although the programmed end-product is incomplete and greatly simplifies the true nature of such a design problem, the lessons learned are distilled and clarified to provide a basis for further work and investigation in this field. The first part is a synopsis of issues related to computer-aided design: an historic overview, current applications, on-going research and forecasts. This section is provided to illustrate the foundation of understanding that I had when undertaking to develop tools of my own. The second part includes the initial tool concepts and their intended purposes, a discussion of hardware and software platforms, and numerous considerations I was compelled to address while developing modeling and information-handling components of the design environment. Part three deals in depth with a sophisticated tool proposal for instantiating urban type elements for illustrating a possible "realization" of a schematic design; this tool was not able to be developed on the chosen platform. I have also included some possible scenarios for using the modeling and information handling tools.by Joseph M. Knight.M.S

Assessing the quality of absolute hydration free energies among CHARMM‐compatible ligand parameterization schemes

Multipurpose atom‐typer for CHARMM (MATCH), an atom‐typing toolset for molecular mechanics force fields, was recently developed in our laboratory. Here, we assess the ability of MATCH‐generated parameters and partial atomic charges to reproduce experimental absolute hydration free energies for a series of 457 small neutral molecules in GBMV2, Generalized Born with a smooth SWitching (GBSW), and fast analytical continuum treatment of solvation (FACTS) implicit solvent models. The quality of hydration free energies associated with small molecule parameters obtained from ParamChem, SwissParam, and Antechamber are compared. Given optimized surface tension coefficients for scaling the surface area term in the nonpolar contribution, these automated parameterization schemes with GBMV2 and GBSW demonstrate reasonable agreement with experimental hydration free energies (average unsigned errors of 0.9–1.5 kcal/mol and R 2 of 0.63–0.87). GBMV2 and GBSW consistently provide slightly more accurate estimates than FACTS, whereas Antechamber parameters yield marginally more accurate estimates than the current generation of MATCH, ParamChem, and SwissParam parameterization strategies. Modeling with MATCH libraries that are derived from different CHARMM topology and parameter files highlights the importance of having sufficient coverage of chemical space within the underlying databases of these automated schemes and the benefit of targeting specific functional groups for parameterization efforts to maximize both the breadth and the depth of the parameterized space. © 2013 Wiley Periodicals, Inc. Ligand parameterization for molecular mechanics simulations is computationally intensive, requiring long multistep optimization procedures. Recently there has been an influx of automated parameterization tools for the CHARMM force field. These tools radically speed up the process, but it remains unclear whether accuracy is sacrificed to a significant extent. The research presented in this article uses a set of 457 small molecules to quantify the accuracy of four automated parameterization tools by computing absolute hydration free energies.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/97284/1/23199_ftp.pd
