Project SEARCH: Analysis of Employment Outcomes for Students with Disabilities Across Two Districts
Rehabilitation professionals have a major focus on competitive employment, which is a central component of adult life that provides not only economic benefits, but also a social network and enhanced self-esteem. The employment gap for individuals with disabilities has remained consistently high despite concerted efforts to provide access to quality job readiness training and a simultaneous increase in awareness of the value of diversity in the workforce. This study examined the outcomes of Project SEARCH, an employer-based transition program for young adults with disabilities that promotes partnerships among the school and community by utilizing a unique collaborative approach that brings the education system, employers, and rehabilitation services together to provide meaningful individualized employment experiences for students with disabilities. Findings suggest Project SEARCH appears to have the potential to address employment outcomes for young adults with various disabilities. Implications for practice and future research are also discussed

Classification of first branchial cleft anomalies: is it clinically relevant?
Background: There are three classification systems for first branchial cleft anomalies currently in use. The Arnot, Work and Olsen classifications describe these lesions on the basis of morphology, tissue of origin and clinical appearance. However, the clinical relevance of these classifications is debated, as they may not be readily applicable in all cases and may provide no additional information on how the lesion should be managed.Objective: We seek to investigate this issue by applying these classification systems to cases from our centre and evaluating the information gained.Patients and methods: A retrospective case note review of all first branchial cleft anomalies excised at our institution between 2004 and 2014 was carried out, recording patient demographics, information on the anomalies and how they were investigated and managed.Results: This search identified eight unilateral cases and one bilateral case of first branchial cleft anomalies. These were a heterogenous group of lesions, which were variably investigated and managed. Categorization of these cases into Arnot, Work and Olsen subtypes did not correlate with the lesion’s relation with the facial nerve or the outcome of excision.Conclusion: The current classification systems used for first branchial cleft anomalies have little clinical relevance apart from providing extensive descriptions to aid in diagnosis. We advise instead that clinicians use imaging techniques to gain as much information as possible about these lesions before excision and be aware of the risk to the facial nerve at the time of excision. A description of the lesion’s relation with the facial nerve at the time of excision may provide more information on the likely outcomes compared with the classifications currently in use.Keywords: branchial cleft, congenital anomaly, facial nerve injury, first branchial cleft anomal
Age-stratified heritability estimation in the Framingham Heart Study families
The Framingham Heart Study provides a unique source of longitudinal family data related to CVD risk factors. Age-stratified heritability estimates were obtained over three age groups (31–49 years, 50–60 years, and 61–79 years), reflecting the longitudinal nature of the data, for four quantitative traits. Age-adjusted heritability estimates were obtained at a single common time point for the same four quantitative traits. The importance of these groups is that they consist of the same individuals. The highest age-stratified heritability estimate (h(2 )= 0.88 (± 0.06)) was for height in the model adjusting for gender over all three age groups. SBP gave the lowest heritability estimate (h(2 )= 0.15 (± 0.11)) for the 70 age group in the model adjusting for gender, height, BMI, smoker, and drinker. BMI had slightly higher estimates (h(2 )= 0.64 (± 0.11)) in the 40 age group than previously published. The highest age-adjusted heritability estimate (h(2 )= 0.90 (± 0.06)) was for height in the model adjusting for gender. SBP gave the lowest heritability estimate (h(2 )= 0.38 (± 0.09)) for unadjusted model. These results indicate that some common, complex traits may vary little in their genetic architecture over time and suggest that a common set of genes may be contributing to observed variation for these longitudinally collected phenotypes
Registration between DCT and EBSD datasets for multiphase microstructures
The ability to characterise the three-dimensional microstructure of
multiphase materials is essential for understanding the interaction between
phases and associated materials properties. Here, laboratory-based
diffraction-contrast tomography (DCT), a recently-established materials
characterization technique that can determine grain phases, morphologies,
positions and orientations in a voxel-based reconstruction method, was used to
map part of a dual-phase steel alloy sample. To assess the resulting
microstructures that were produced by the DCT technique, an EBSD map was
collected within the same sample volume. To identify the 2D slice of the 3D DCT
reconstruction that best corresponded to the EBSD map, a novel registration
technique based solely on grain-averaged orientations was developed -- this
registration technique requires very little a priori knowledge of dataset
alignment and can be extended to other techniques that only recover
grain-averaged orientation data such as far-field 3D X-ray diffraction
microscopy. Once the corresponding 2D slice was identified in the DCT dataset,
comparisons of phase balance, grain size, shape and texture were performed
between DCT and EBSD techniques. More complicated aspects of the
microstructural morphology such as grain boundary shape and grains less than a
critical size were poorly reproduced by the DCT reconstruction, primarily due
to the difference in resolutions of the technique compared with EBSD. However,
lab-based DCT is shown to accurately determine the centre-of-mass position,
orientation, and size of the large grains for each phase present, austenite and
martensitic ferrite. The results reveals a complex ferrite grain network of
similar crystal orientations that are absent from the EBSD dataset. Such detail
demonstrates that lab-based DCT, as a technique, shows great promise in the
field of multi-phase material characterization.Comment: 15 pages, 11 figures. Preprint submitted to Materials

Ares I-X Range Safety Simulation Verification and Analysis Independent Validation and Verification
NASA s Ares I-X vehicle launched on a suborbital test flight from the Eastern Range in Florida on October 28, 2009. To obtain approval for launch, a range safety final flight data package was generated to meet the data requirements defined in the Air Force Space Command Manual 91-710 Volume 2. The delivery included products such as a nominal trajectory, trajectory envelopes, stage disposal data and footprints, and a malfunction turn analysis. The Air Force s 45th Space Wing uses these products to ensure public and launch area safety. Due to the criticality of these data, an independent validation and verification effort was undertaken to ensure data quality and adherence to requirements. As a result, the product package was delivered with the confidence that independent organizations using separate simulation software generated data to meet the range requirements and yielded consistent results. This document captures Ares I-X final flight data package verification and validation analysis, including the methodology used to validate and verify simulation inputs, execution, and results and presents lessons learned during the proces

Students’ Sense of Belonging: The Development of a Predictive Retention Model
Educational institutions increasingly recognize the role that student belonging plays in retention. Many studies in this area focus on helping students improve a sense of belonging before they matriculate or identifying belonging as a reason for their departure. This study measures students’ sense of belonging at key transition points during the first year and finds that social belonging and academic performance are both strong predictors of retention that are not necessarily correlated. These results suggest that a comprehensive, focused outreach protocol that encompasses both social and academic factors could have a positive impact on student persistence
Lepton Flavour Violation in a Class of Lopsided SO(10) Models
A class of predictive SO(10) grand unified theories with highly asymmetric
mass matrices, known as lopsided textures, has been developed to accommodate
the observed mixing in the neutrino sector. The model class effectively
determines the rate for charged lepton flavour violation, and in particular the
branching ratio for , assuming that the supersymmetric GUT
breaks directly to the constrained minimal supersymmetric standard model
(CMSSM). We find that in light of the combined constraints on the CMSSM
parameters from direct searches and from the WMAP satellite observations, the
resulting predicted rate for in this model class can be
within the current experimental bounds for low , but that the next
generation of experiments would effectively rule out this
model class if LFV is not detected.Comment: 23 page
