Positive solutions of a boundary value problem with integral boundary conditions

We consider boundary-value problems studied in a recent paper. We show that some existing theory developed by Webb and Infante applies to this problem and we use the known theory to show how to find improved estimates on parameters μ*, λ so that some nonlinear differential equations, with nonlocal boundary conditions of integral type, have two positive solutions for all λ with μ*< λ < λ

The Monster in Our House: Racial Incidents on College Campuses

Reports of racial incidents on college campuses have risen dramatically in the past four years. Data from recent surveys indicate that minority students, specifically blacks, will experience some form of discrimination during their academic careers.[1] Recent data from other studies reveal that racial and ethnic violence has occurred on at least 70 U.S. college campuses.[2] Efforts to assert one racial/ethnic group over another have often created social conflicts. These social disagreements may take several forms, usually imitating behavior outside of school: shouting discriminatory remarks or becoming physically aggressive or violent

Diagnosing performance management and performance budgeting systems: A case study of the U.S. Navy

We present here a case study of an organization within the U.S. Navy that created a new organizational construct and performance management system. We explore the issues faced by naval leaders as they attempt to use their performance information to make resource allocation decisions at the sub-organization level, and base budgets at the organization and service (navy) level. We attempt to diagnose many of the practical problems a government organization encounters when implementing a performance management system, to include trying to inform budgets, and make recommendations on actions that would improve the strength of the performance system. We find in the organization a good conceptual framework, organizational enthusiasm, and reasonable attempts to link disparate information systems into a coherent whole. The good intentions are hindered, however, by inadequate accounting systems, a lack of understanding of cost accounting methods, weak use of terminology and longstanding institutional attitudes. This case confirms challenges associated with both performance management systems and performance budgeting found in the literature, and we offer recommendations for public officials considering such endeavors

Rotating bubble membrane radiator for space applications

An advanced radiator concept for heat rejection in space is described which uses a two-phase working fluid to radiate waste heat. The development of advanced materials and the large surface area per mass makes the Bubble Membrane Radiator an attractive alternative to both conventional heat pipes and liquid droplet radiators for mid to high temperature applications. A system description, a discussion of design requirements, and a mass comparison with heat pipes and liquid droplet radiators are provided
