IMPLICATIONS OF EARLY VENDOR DOWN-SELECT IN DEFENSE ACQUISITION PROGRAMS

This study examines the impact of early vendor down-selection on the competition within defense acquisition programs, with a specific focus on its effects on cost, schedule, and performance outcomes. By conducting a comparative case study analysis of programs that employed early down-selection versus those that maintained multiple vendors, the research highlights how reduced competition correlates with increased risks and negative outcomes, including cost overruns and project delays. The findings advocate for maintaining competitive dynamics throughout the acquisition process as a strategy to improve overall program success and efficiency. This study contributes to the ongoing discourse on optimal acquisition strategies in the defense sector, suggesting a reevaluation of current practices to enhance competitive forces within the acquisition framework.Distribution Statement A.

Total versus superficial parotidectomy for stage III melanoma

BackgroundThe primary purpose of this study was to describe the parotid recurrence rates after superficial and total parotidectomy.MethodsA retrospective cohort study was performed on patients with cutaneous melanoma metastatic to the parotid gland who underwent parotidectomy from 1998 through 2014. Primary outcome was parotid bed recurrence. Secondary outcomes were facial nerve function postoperatively and at last follow‐up.ResultsOne hundred twenty‐nine patients were included in the study. Thirty‐four patients (26%) underwent a total parotidectomy and 95 patients underwent superficial parotidectomy. Twelve patients (13%) developed parotid bed recurrence after superficial parotidectomy alone versus zero after total parotidectomy (P = .035). Facial nerve function, clinically detected disease, stage, and adjuvant treatment were not statistically different between the groups (P = .32, .32, .13, and 0.99, respectively).ConclusionParotid bed melanoma recurrence was more common after superficial parotidectomy compared to total parotidectomy, and recurrence resulted in significant facial nerve functional deficit. Our results support total parotidectomy when metastatic melanoma involves the parotid nodal basin.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/137735/1/hed24810_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/137735/2/hed24810.pd

Advancing Alternative Analysis: Integration of Decision Science.

Decision analysis-a systematic approach to solving complex problems-offers tools and frameworks to support decision making that are increasingly being applied to environmental challenges. Alternatives analysis is a method used in regulation and product design to identify, compare, and evaluate the safety and viability of potential substitutes for hazardous chemicals.Assess whether decision science may assist the alternatives analysis decision maker in comparing alternatives across a range of metrics.A workshop was convened that included representatives from government, academia, business, and civil society and included experts in toxicology, decision science, alternatives assessment, engineering, and law and policy. Participants were divided into two groups and prompted with targeted questions. Throughout the workshop, the groups periodically came together in plenary sessions to reflect on other groups' findings.We conclude the further incorporation of decision science into alternatives analysis would advance the ability of companies and regulators to select alternatives to harmful ingredients, and would also advance the science of decision analysis.We advance four recommendations: (1) engaging the systematic development and evaluation of decision approaches and tools; (2) using case studies to advance the integration of decision analysis into alternatives analysis; (3) supporting transdisciplinary research; and (4) supporting education and outreach efforts

Wii-Fit for Improving Gait and Balance in an Assisted Living Facility: A Pilot Study

Objectives. To determine the effects on balance and gait of a Wii-Fit program compared to a walking program in subjects with mild Alzheimer's dementia (AD). Methods. A prospective randomized (1 : 1) pilot study with two intervention arms was conducted in an assisted living facility with twenty-two mild AD subjects. In both groups the intervention occurred under supervision for 30 minutes daily, five times a week for eight weeks. Repeated measures ANOVA and paired t-tests were used to analyze changes. Results. Both groups showed improvement in Berg Balance Scale (BBS), Tinetti Test (TT) and Timed Up and Go (TUG) over 8 weeks. However, there was no statistically significant difference between the groups over time. Intragroup analysis in the Wii-Fit group showed significant improvement on BBS (P = 0.003), and TT (P = 0.013). The walking group showed a trend towards improvement on BBS (P = 0.06) and TUG (P = 0.07) and significant improvement in TT (P = 0.06). Conclusion. This pilot study demonstrates the safety and efficacy of Wii-Fit in an assisted living facility in subjects with mild AD. Use of Wii-Fit resulted in significant improvements in balance and gait comparable to those in the robust monitored walking program. These results need to be confirmed in a larger, methodologically sound study

Report of the AACP Task Force on Patient-Centered Medical Homes and Accountable Care Organizations

A task force was convened by the American Association of Colleges of Pharmacy (AACP) to provide rationale for academic pharmacy engagement with organizations/institutions providing new models of team-based patient care designed to improve patient access, care quality, and affordable care. Descriptions of new care models, such as patient centered medical homes (PCMHs) and accountable care organizations (ACO), were included as well as descriptions of existing partnerships with academic pharmacy

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

A Redesign of the ACGME Resident/Fellow Survey Through Expert Reviews and Cognitive Interviews.

BACKGROUND: Since 2003, the Accreditation Council for Graduate Medical Education (ACGME) has surveyed residents and fellows in its accredited programs. The Resident/Fellow Survey is a screening and compliance tool that programs can also use for continuous quality improvement. However, stakeholders have reported potential problems with the survey\u27s overall quality and credibility. OBJECTIVE: To redesign the 2006 Resident/Fellow Survey using expert reviews and cognitive interviews. METHODS: In 2018-2019, the ACGME redesigned the Resident/Fellow Survey using an iterative validation process: expert reviews (evidence based on content) and cognitive interviews (evidence based on response processes). Expert reviews were conducted by a survey design firm and an ACGME Task Force; cognitive interviews were conducted with a diverse set of 27 residents and fellows. RESULTS: Expert reviews resulted in 21 new survey items to address the ACGME\u27s updated accreditation requirements; these reviews also led to improvements that align the survey items with evidence-informed standards. After these changes were made, cognitive interviews resulted in additional revisions to sensitive items, item order, and response option order, labels, and conceptual spacing. In all, cognitive interviews led to 11 item deletions and other improvements designed to reduce response error. CONCLUSIONS: Expert reviews and cognitive interviews were used to redesign the Resident/Fellow Survey. The content of the redesigned survey aligns with the updated accreditation requirements and items are written in accordance with evidence-informed standards. Additionally, cognitive interviews resulted in revisions to the survey that seem to improve respondents\u27 comprehension and willingness to respond to individual survey items
