Roles and Responsibilities of Nonprofit Boards: the Peace Case
This exploratory study identifies the levels of importance and fulfillment of board roles and responsibilities by nonprofit peacemaking organization board members and executive directors. It suggests a three-component framework for understanding board governance. By employing purposive non-probability sampling, this study used board governance instruments, developed by Inglis, Alexander, and Weaver\u27s (1999, 163-165), to identify a three-component framework: strategic activities, resource planning, and evaluations for nonprofit organizations whose mission is peacemaking. It examines the relevance of the framework suggested by Inglis, Alexander, and Weavers (1999, 161-165) for nonprofit peacemaking organizations. The results of this study can be used by nonprofit peacemaking organizations to improve their governance capacity and prompt future research about the governance of nonprofit peacemaking organizational boards

Electrical networks and Lie theory
We introduce a new class of "electrical" Lie groups. These Lie groups, or
more precisely their nonnegative parts, act on the space of planar electrical
networks via combinatorial operations previously studied by
Curtis-Ingerman-Morrow. The corresponding electrical Lie algebras are obtained
by deforming the Serre relations of a semisimple Lie algebra in a way suggested
by the star-triangle transformation of electrical networks. Rather
surprisingly, we show that the type A electrical Lie group is isomorphic to the
symplectic group. The nonnegative part (EL_{2n})_{\geq 0} of the electrical Lie
group is a rather precise analogue of the totally nonnegative subsemigroup
(U_{n})_{\geq 0} of the unipotent subgroup of SL_{n}. We establish
decomposition and parametrization results for (EL_{2n})_{\geq 0}, paralleling
Lusztig's work in total nonnegativity, and work of Curtis-Ingerman-Morrow and
de Verdi\`{e}re-Gitler-Vertigan for networks. Finally, we suggest a
generalization of electrical Lie algebras to all Dynkin types.Comment: 14 pages, 5 figure
Selected experiments in laminar flow: An annotated bibliography
Since the 1930s, there have been attempts to reduce drag on airplanes by delaying laminar to turbulent boundary layer transition. Experiments conducted during the 1940's, while successful in delaying transition, were discouraging because of the careful surface preparation necessary to meet roughness and waviness requirements. The resulting lull in research lasted nearly 30 years. By the late 1970s, airframe construction techniques had advanced sufficiently that the high surface quality required for natural laminar flow (NLF) and laminar flow control (LFC) appeared possible on production aircraft. As a result, NLF and LFC research became widespread. This report is an overview of that research. The experiments summarized herein were selected for their applicability to small transonic aircraft. Both flight and wind tunnel tests are included. The description of each experiment is followed by corresponding references. Part One summarizes NLF experiments; Part Two deals with LFC and hybrid laminar flow control (HLFC) experiments
Constitutional rights law and its limitations: topical examples
One consequence of the post-World War II ‘rights revolution’ is the ever growing use of constitutional law to protect fundamental rights. The goal of this is not only to protect such rights by judicial enforcement, at which it can be relatively successful, but to ultimately place them beyond political contestation.[1] However, it is regularly argued that placing rights beyond political contestation is very difficult to achieve where deep and sustained disagreement over rights exists.[2
