Public-private Partnerships for Government Financing, Controlling Risk, and Value-for--money: The UK Experience

Sponsored Report (for Acquisition Research Program)One of the key requirements to a successful Public-private Partnership (PPP) is the transfer of risk from the government to the private sector. This research examines the PPP experience in the United Kingdom (UK) Ministry of Defense to determine if they would be applicable to the US Department of Defense (DoD). PPP agreements have provided the UK increased capabilities. Also, this research provides an in-depth analysis of Private Financed Initiatives (PFI) that Serco Inc. has undertaken. Finally, this research evaluates the increases in value-for-money resulting from the PPP transfer of risk to the private sector. The research concludes that PPPs should be continued and expanded to provide increased real-time capability to the DoD while supporting private industry. Since the government has the lowest cost of borrowing, PPPs agreements may not appear to be cost effective as a means of procurement. However, the benefits from transferring risk to the private sector can more than offset the higher financing cost. PPPs reallocate risk and up-front capital requirements allowing the government to spread program cost over time. Without initial capital outlays, the government can acquire higher priority goods and services with its limited resources. In addition, PPPs provide the government with an increased infrastructure and technological capability than would otherwise not be available.Naval Postgraduate School Acquisition Research ProgramApproved for public release; distribution is unlimited

Using public-private partnerships and energy savings contracts to fund DoD mobile assets

The Department of Defense (DoD) has engaged in numerous Public-Private Partnership (PPP) ventures such as outsourcing of services and privatization of military housing. In the past, the activities considered for PPPs have been primarily administrative and support functions. This research explores the possibility of expanding the use of PPPs to enhance the DoD combat and combat-support functions. First, to better understand how PPPs function (the partnership relationships and financing arrangements), we examine Hannon Armstrong's fee for service contract solution to the lack of appropriated funds for establishing a vital fiber-optic link near the Arctic Circle. Next, we explore the history of Energy Savings Performance Contracts (ESPCs) and their potential application to re-engining the Air Force's B-52H through PPPs. Historically, this program has only been used for fixed assets, not mobile assets like engines. There is little debate over the success of ESPC contracts in reducing energy consumption, but their use in DoD mobile assets is new. Finally, we conclude that applying ESPCs to mobile assets has the potential to reduce energy consumption, save millions of dollars and increase combat efficiency.Approved for public release; distribution is unlimited

Navy Acquisition via leasing: policy, politics, and polemics with the Maritime Prepositioned Ships

In recent months, leasing has been prominent in the press in connection with the Air Force's ill-fated attempt to obtain the use of Boeing re-fueling tankers without buying them. Gone from memory is the early 1980's controversial Navy leasing program of Maritime Pre-positioned Ships that had a different result. This paper presents an analysis of the various issues and parties to the very creative and innovative financing on behalf of the Navy's Military Sealift Command. Still in existence today, the 1983 contracts for thirteen TAKX ships were valued at approximately $2.6 billion. While the decision is often framed as a lease versus purchase choice, the facts indicate that the option to purchase was not seen as viable at the time. In hindsight, the TAKX leasing program was successful and cost effective, despite the whirlwind of political commentary and intrigue and the dueling quantitative analyses surrounding it. However, as an unintended (or, perhaps, intended) consequence, laws and policies have since been changed so that leasing is no longer viable for financing military assets. The case presented here considers altering existing laws and regulations to once again permit leasing of military resources.Approved for public release; distribution is unlimited

Pomalidomide – An Appraisal of Its Clinical Development and Role in the Treatment of Relapsed/Refractory Multiple Myeloma

Pomalidomide is a distinct immunomodulatory agent with significant activity in relapsed/refractory multiple myeloma (RRMM). The optimal treatment schedule in patients with RRMM who have received multiple lines of treatment, including bortezomib and lenalidomide, is 4 mg/day on days 1–21 of a 28-day cycle in combination with weekly low-dose dexamethasone. Improved responses and outcomes relative to traditional therapies continue to be confirmed in recently completed and ongoing trials. Pomalidomide exhibits direct tumoricidal, immunomodulatory, anti-angiogenic and anti-inflammatory activities, which facilitate combination therapy with agents with complementary mechanisms of action, resulting in greater anti-myeloma effects than single-agent therapy or previous combination therapies. For example, in combination with proteasome inhibitors and traditional chemotherapeutic agents in doublet or triplet regimens, pomalidomide provides high rates of durable response, and represents an important new treatment option for patients with RRMM requiring effective new therapies. Additionally, pomalidomide maintains its efficacy and tolerability profile in difficult-to-treat patients, including the elderly, patients with poor cytogenetics and those with renal impairment. This review summarises the clinical development of pomalidomide and discusses this effective agent for the treatment of patients with RRMM in the context of current myeloma treatment options, as well as potential future directions to further improve patient outcomes

Eliciting health state utilities for Dupuytren's contracture using a discrete choice experiment

Background and purpose An internet-based discrete choice experiment (DCE) was conducted to elicit preferences for a wide range of Dupuytren’s contracture (DC)-related health states. An algorithm was subsequently developed to convert these preferences into health state utilities that can be used to assess DC’s impact on quality of life and the value of its treatments. Methods Health state preferences for varying levels of DC hand severity were elicited via an internet survey from a sample of the UK adult population. Severity levels were deined using a combination of contractures (0, 45, or 90 degrees) in 8 proximal interphalangeal and metacarpophalangeal joints of the index, middle, ring, and little ingers. Right-handed, left-handed, and ambidextrous respondents indicated which hand was preferable in each of the 10 randomly-selected hand-pairings comparing different DC severity levels. For consistency across comparisons, anatomically precise digital hand drawings were used. To anchor preferences onto the traditional 0–1 utility scale used in health economic evaluations, unaffected hands were assigned a utility of 1.0 whereas the utility for a maximally affected hand (i.e., all 8 joints set at 90 degrees of contracture) was derived by asking respondents to indicate what combination of attributes and levels of the EQ-5D-5L proile most accurately relects the impact of living with such hand. Conditional logistic models were used to estimate indirect utilities, then rescaled to the anchor points on the EQ-5D-5L. Results Estimated utilities based on the responses of 1,745 qualiied respondents were 0.49, 0.57, and 0.63 for completely affected dominant hands, non-dominant hands, or ambidextrous hands, respectively. Utility for a dominant hand with 90-degree contracture in t h e metacarpophalangeal joints of the ring and little ingers was estimated to be 0.89. Separately, reducing the contracture of metacarpophalangeal joint for a little inger from 50 to 12 degrees would improve utility by 0.02. Interpretation DC is associated with substantial utility decrements. The algorithms presented herein provide a robust and lexible framework to assess utility for varying degrees of DC severity

Status of Muon Collider Research and Development and Future Plans

The status of the research on muon colliders is discussed and plans are outlined for future theoretical and experimental studies. Besides continued work on the parameters of a 3-4 and 0.5 TeV center-of-mass (CoM) energy collider, many studies are now concentrating on a machine near 0.1 TeV (CoM) that could be a factory for the s-channel production of Higgs particles. We discuss the research on the various components in such muon colliders, starting from the proton accelerator needed to generate pions from a heavy-Z target and proceeding through the phase rotation and decay ($\pi \to \mu \nu_{\mu}$) channel, muon cooling, acceleration, storage in a collider ring and the collider detector. We also present theoretical and experimental R & D plans for the next several years that should lead to a better understanding of the design and feasibility issues for all of the components. This report is an update of the progress on the R & D since the Feasibility Study of Muon Colliders presented at the Snowmass'96 Workshop [R. B. Palmer, A. Sessler and A. Tollestrup, Proceedings of the 1996 DPF/DPB Summer Study on High-Energy Physics (Stanford Linear Accelerator Center, Menlo Park, CA, 1997)].Comment: 95 pages, 75 figures.

Detailed Analysis of a Contiguous 22-Mb Region of the Maize Genome

Most of our understanding of plant genome structure and evolution has come from the careful annotation of small (e.g., 100 kb) sequenced genomic regions or from automated annotation of complete genome sequences. Here, we sequenced and carefully annotated a contiguous 22 Mb region of maize chromosome 4 using an improved pseudomolecule for annotation. The sequence segment was comprehensively ordered, oriented, and confirmed using the maize optical map. Nearly 84% of the sequence is composed of transposable elements (TEs) that are mostly nested within each other, of which most families are low-copy. We identified 544 gene models using multiple levels of evidence, as well as five miRNA genes. Gene fragments, many captured by TEs, are prevalent within this region. Elimination of gene redundancy from a tetraploid maize ancestor that originated a few million years ago is responsible in this region for most disruptions of synteny with sorghum and rice. Consistent with other sub-genomic analyses in maize, small RNA mapping showed that many small RNAs match TEs and that most TEs match small RNAs. These results, performed on ∼1% of the maize genome, demonstrate the feasibility of refining the B73 RefGen_v1 genome assembly by incorporating optical map, high-resolution genetic map, and comparative genomic data sets. Such improvements, along with those of gene and repeat annotation, will serve to promote future functional genomic and phylogenomic research in maize and other grasses

Common Genetic Polymorphisms Influence Blood Biomarker Measurements in COPD

Implementing precision medicine for complex diseases such as chronic obstructive lung disease (COPD) will require extensive use of biomarkers and an in-depth understanding of how genetic, epigenetic, and environmental variations contribute to phenotypic diversity and disease progression. A meta-analysis from two large cohorts of current and former smokers with and without COPD [SPIROMICS (N = 750); COPDGene (N = 590)] was used to identify single nucleotide polymorphisms (SNPs) associated with measurement of 88 blood proteins (protein quantitative trait loci; pQTLs). PQTLs consistently replicated between the two cohorts. Features of pQTLs were compared to previously reported expression QTLs (eQTLs). Inference of causal relations of pQTL genotypes, biomarker measurements, and four clinical COPD phenotypes (airflow obstruction, emphysema, exacerbation history, and chronic bronchitis) were explored using conditional independence tests. We identified 527 highly significant (p 10% of measured variation in 13 protein biomarkers, with a single SNP (rs7041; p = 10−392) explaining 71%-75% of the measured variation in vitamin D binding protein (gene = GC). Some of these pQTLs [e.g., pQTLs for VDBP, sRAGE (gene = AGER), surfactant protein D (gene = SFTPD), and TNFRSF10C] have been previously associated with COPD phenotypes. Most pQTLs were local (cis), but distant (trans) pQTL SNPs in the ABO blood group locus were the top pQTL SNPs for five proteins. The inclusion of pQTL SNPs improved the clinical predictive value for the established association of sRAGE and emphysema, and the explanation of variance (R2) for emphysema improved from 0.3 to 0.4 when the pQTL SNP was included in the model along with clinical covariates. Causal modeling provided insight into specific pQTL-disease relationships for airflow obstruction and emphysema. In conclusion, given the frequency of highly significant local pQTLs, the large amount of variance potentially explained by pQTL, and the differences observed between pQTLs and eQTLs SNPs, we recommend that protein biomarker-disease association studies take into account the potential effect of common local SNPs and that pQTLs be integrated along with eQTLs to uncover disease mechanisms. Large-scale blood biomarker studies would also benefit from close attention to the ABO blood group
