 | What caused the agricultural manpower shortage in World War II? Historians have proffered a variety of explanations that attribute linear causality to a handful of independent variables. No scholar, however, has attempted to study the manpower shortage in its full causal complexity. This thesis, following the muse of analytic eclecticism, assembles a variety of cutting-edge political-science scholarship to develop a modified version of the Institutional Analysis Framework. The thesis applies ... |

| The terrorist attacks of 11 September 2001 (9/11) exposed an analytical deficiency within the intelligence community. However, the US Air Force has invested in expanding collection capacity, as evidenced by the 375 intelligence, surveillance, and reconnaissance (ISR) platforms added since 9/11.+ More remarkably, the increase in ISR platforms has come at a time when the total Air Force inventory has decreased by 500 aircraft. ISR platforms such as the RQ-4, ... |

|
| Research shows that continuing competitive pressure applied during development and production leads to better industry performance, often at reduced cost. However, the entrenched practice of one-time competition for an entire program life-cycle often endows the winner with a very strong monopolistic power that lasts for decades. This paper describes continuous competition as leverage to acquire more effective results. It offers an alternative method for continuous competition-Multi-sourcing with Distributed Awards-under an ... |

Conflict analysis has identified that internal conflict has significant adverse effects on civilian populations. Apart from increased casualties arising out of collateral damage, civilian populations also suffer loss of income, destruction of property and food stores, internal displacement, and even involuntary conscription and forced labor. Reducing internal conflict is part of conflict prevention. Research into economic theories ... |

| DoD acquisition efforts have not improved significantly since at least the 1960s, when the first large scale analysis of DoD acquisition performance took place. The Department of Defense (DoD) continues to face numerous difficulties in its acquisition of Major Defense Acquisition Projects (MDAPs). A 2006 RAND report found that the average adjusted total cost growth for a completed program was 46 percent (RAND TR-343). The roughly 100 MDAPs under development ... |

| Experiments were designed to evaluate the corrosion-related consequences of storing/transporting fatty acid methyl ester (FAME) alternative diesel fuel in contact with natural seawater. Coastal Key West, FL (KW), and Persian Gulf (PG) seawaters, representing an oligotrophic and a more organic- and inorganic mineral-rich environment, respectively, were used in 60 day incubations with unprotected carbon steel. The original microflora of the two seawaters were similar with respect to major taxonomic groups ... |

| We examine the relationship between fiscal decentralization and the functional composition of public expenditures. Using a distance-sensitive representative agent model, we hypothesize that higher levels of fiscal decentralization induce agents to demand increased production of publicly provided private goods. We test this hypothesis using an unbalanced panel data set of 59 developed and developing countries covering a 30-year period. We find that expenditure decentralization positively and significantly influences the share ... |

| Flukes are distally located extensions of the tail, and from a biomechanical standpoint, function as a pair of wings (Vogel 1994). Flukes function to produce thrust generated as an anteriorly directed lift force as flukes oscillate vertically (Fish 1998a, b). Their cross-sections resemble hydrofoils. For a hydrofoil to be effective, a large lift must be produced while drag is minimized; this, in turn, increases the thrust generated (Weihs 1989, Vogel ... |

| Liquid resins used for molding composite structures are a significant source of hazardous air pollutant (HAP) emissions. One method of reducing styrene emissions from vinyl ester (VE) resins is to replace some or all of the styrene with fatty acid-based monomers. Fatty acid monomers are ideal candidates because they are inexpensive, have low volatilities, and promote global sustainability because they are derived from renewable resources. This patented technology allows for ... |

| Type II methanotrophs produce polyhydroxybutyrate (PHB), while Type I methanotrophs do not. A laboratory-scale fluidized bed reactor was initially inoculated with a Type II Methylocystis-like dominated culture. At elevated levels of dissolved oxygen (DO, 9 mg/L), pH of 6.2-6.5 with nitrate as the N-source a Methylobacter-like Type I methanotroph became dominant within the biofilms which did not produce PHB. A shift to biofilms capable of PHB production was achieved by ... |

| Developing a weapon while in production does increase program risk and is sometimes cited as a reason for cost growth. This article explores the relationship between concurrency and cost growth in large weapon programs. The authors defined concurrency as the proportion of research, development, and test and evaluation appropriations authorized during the same years in which procurement appropriations are authorized. Their results strongly indicate that concurrency does not necessarily predict ... |

| Typically, defense programs experience some level of concurrency; that is, production of the weapon system happens while some portions of the design are still being completed. Many people within the defense acquisition community argue that high levels of design/ build concurrency ultimately lead to cost growth, as it implicitly creates a greater level of risk. For example, a memorandum from the Assistant Secretary of the Navy for Research, Development and ... |
