Nebraska Vocational and Life Skills Initiative Client Perceptions of Program Services and Ability to Reintegrate: A Qualitative Analysis of Grant Cycle 1 Participant Interviews

This report provides a detailed analysis of client perceptions of services they received as part of the Vocational and Life Skills (VLS) first grant cycle. Approximately 2500 participants received services as part of the first grant cycle of the Life Skills Program created in 2014 by Nebraska Legislative Bill 907. VLS programming focused on reentry of individuals currently incarcerated, recently released from one of the ten Nebraska correctional facilities, or clients supervised in the community via probation or parole. VLS services included a range of job readiness, educational, and career trainings as well as and a number of mental health, therapeutic and substance treatment programs. In the first grant cycle, services were provided by eight organizations: Center for People in Need, Goodwill Industries, Mental Health Association of Nebraska, Metropolitan Community College, Prairie Gold Homes, Released and Restored, Inc., ResCare Workforce Services, and Western Alternative Corrections. As part of the evaluation of the VLS program, 27 clients were interviewed in 2016 to ascertain their general perceptions of the programming, assess changes in behavioral and life skills, and describe their general reentry experience. The interviewed participants included clients from each of the eight program sites and a mix of those preparing for release from a correction facility, under parole or other community supervision at the time of the interview, or those recently released from supervision after completing all required supervision conditions. This extensive qualitative data offers detailed information of client experiences and adds additional context to survey data previously collected on VLS Cycle 1 participants. 4 Analysis of interview data indicates that the majority of those receiving services found the programs beneficial for their reentry process. Important positive themes identified in the data included the merits of expressive and instrumental social supports by program staff, the value of job skills and educational trainings, and behavioral shifts and life course changes. Clients also presented a number of concerns that could negatively influence reentry outcomes. More than half of all participants believed that they faced blocked opportunities associated with their criminal past and 66% reported not feeling connected to a community. One participant described feeling like a “ghost” in the community

Examining the Lived Experience of Mild Cognitive Impairment: An Evidence-Based Practice Project

This Evidence-Based Practice (EBP) project addressed the following question: What are the perspectives, experiences, and self-reports of adult individuals, groups, or populations who have MCI or report problems with Functional Cognition (and / or their caregivers)

Improved Photometric Redshifts with Surface Luminosity Priors

We apply Bayesian statistics with prior probabilities of galaxy surface luminosity (SL) to improve photometric redshifts. We apply the method to a sample of 1266 galaxies with spectroscopic redshifts in the GOODS North and South fields at 0.1 < z < 2.0. We start with spectrophotometric redshifts (SPZs) based on Probing Evolution and Reionization Spectroscopically grism spectra, which cover a wavelength range of 6000-9000A, combined with (U)BViz(JHK) broadband photometry in the GOODS fields. The accuracy of SPZ redshifts is estimated to be \sigma (\Delta(z))=0.035 with an systematic offset of -0.026, where \Delta(z)=\Delta z / (1+z), for galaxies in redshift range of 0.5 < z < 1.25. The addition of the SL prior probability helps break the degeneracy of SPZ redshifts between low redshift 4000 A break galaxies and high-redshift Lyman break galaxies which are mostly catastrophic outliers. For the 1138 galaxies at z < 1.6, the fraction of galaxies with redshift deviation \Delta (z) > 0.2 is reduced from 15.0% to 10.4%, while the rms scatter of the fractional redshift error does not change much.Comment: 7 pages, 7 figures, published in A

Author-choice open access publishing in the biological and medical literature: a citation analysis

In this article, we analyze the citations to articles published in 11 biological and medical journals from 2003 to 2007 that employ author-choice open access models. Controlling for known explanatory predictors of citations, only 2 of the 11 journals show positive and significant open access effects. Analyzing all journals together, we report a small but significant increase in article citations of 17%. In addition, there is strong evidence to suggest that the open access advantage is declining by about 7% per year, from 32% in 2004 to 11% in 2007.Comment: citation changes; final manuscrip

“Click”-Capture, ROMP, Release: Facile Triazolation Utilizing ROMP-derived Oligomeric Phosphates

Soluble, high-load ROMP-derived oligomeric triazole phosphates (OTP) are reported for application as efficient triazolating reagents of nucleophilic species. Utilizing a “Click”-capture, ROMP, release protocol, the efficient and purification free, direct triazolation of N-, O- and S-nucleophilic species was successfully achieved. A variety of OTP derivatives were rapidly synthesized as free-flowing solids on multi-gram scale from commercially available materials

Monomer-on-Monomer (MoM) Mitsunobu Reaction: Facile Purification Utilizing Surface-Initiated Sequestration

A monomer-on-monomer (MoM) Mitsunobu reaction utilizing norbornenyl-tagged (Nb-tagged) reagents is reported, whereby purification was rapidly achieved by employing ring-opening metathesis polymerization which is initiated by any of three methods utilizing Grubbs catalyst (i) free catalyst in solution, (ii) surface-initiated catalyst-armed silica or (iii) surface-initiated catalyst-armed Co/C magnetic nanoparticles

Mechanically stacked four-junction concentrator solar cells

Multijunction solar cells can be fabricated by bonding together component cells that are grown separately. Because the component cells are each grown lattice-matched to suitable substrates, this technique allows alloys of different lattice constants to be combined without the structural defects introduced when using metamorphic buffers. Here we present results on the fabrication and performance of four-junction mechanical stacks composed of GaInP/GaAs and GaInAsP/GaInAs tandems, grown on GaAs and InP substrates, respectively. The two tandems were bonded together with a lowindex, transparent epoxy that acts as an omni-directional reflector to the GaAs bandedge luminescence, while simultaneously transmitting nearly all of the sub-bandgap light. As determined by electroluminescence measurements and optical modeling, the GaAs subcell demonstrates a higher internal radiative limit and thus higher subcell voltage, compared with GaAs subcells without enhanced internal optics; all four subcells exhibit excellent material quality. The device was fabricated with four contact terminals so that each tandem can be operated at its maximum power point, which raises the cumulative efficiency and decreases spectral sensitivity. Efficiencies exceeding 38% at one-sun have been demonstrated. Eliminating the series resistance is the key challenge for the concentrator cells. We will discuss the performance of one-sun and concentrator versions of the device, and compare the results to recently fabricated monolithic four-junction cells
