    Description: This paper describes the completion of a 'comprehensive study of regionalism' that was conducted by a joint team of economists and economic development specialists for the Economic Development Administration (EDA). The project consisted of two main activities: an examination of the factors associated with economic development success and the creation of a practical interactive tool for EDA project assessment and comparison. Findings from surveys, interviews, and project case studies are discussed in terms of their support for a positive relationship between successful economic development efforts and factors such as leadership and private investment. Also, the authors discuss the creation of a quantitative assessment model utilizing well-known approaches such as economic impact multipliers and cluster theory. The primary contribution of this work to the existing body of EDA-focused research and evaluation literature is introducing a means of using standardized scores, also known as z-scores, to compare and assess economic development projects across both industries and regions.

    Description: A model of group formation is presented where the number of groups is fixed and a person can only join a group if the group’s members approve the person’s joining. Agents have either local status preferences (each agent wants to be the highest status agent in his group) or global status preferences (each agent wants to join the highest status group that she can join). For both preference types, conditions are provided which guarantee the existence of a segregated stable partition where similar people are grouped together and conditions are provided which guarantee the existence of an integrated stable partition where dissimilar people are grouped together. Additionally, in a dynamic framework we show that if a new empty group is added to a segregated stable partition, then integration may occur.

    Description: We examine a new class of games, which we call social games, where players not only choose strategies but also choose with whom they play. A group of players who are dissatisfied with the play of their current partners can join together and play a new equilibrium. This imposes new refinements on equilibrium play, where play depends on the relative populations of players in different roles, among other things. We also examine finite repetitions of games where players may choose to rematch in any period. Some equilibria of fixed-player repeated games cannot be sustained as equilibria in a repeated social game. Conversely, the set of repeated matching (or social) equilibria also includes some plays that are not part of any subgame perfect equilibrium of the corresponding fixed-player repeated games. We explore existence under different equilibrium definitions, as well as the relationship to renegotiation-proof equilibrium. It is possible for repeated matching equilibria to be completely distinct from renegotiation-proof equilibria, and even to be Pareto inefficient.

    Notes: Co-extrusion processing is a powder-based forming method that uses thesimultaneous ram extrusion of two or more materials to form multi-phase systemswith functionally designed architectures. A functionally designed material hasfunctional properties that are specifically tailored for an application by changing themacrostructure (100’s of microns) with little or no change in overall composition.Thus, co-extrusion can be used to improve the functional properties of compositematerials, with or without a concurrent boost of its intrinsic properties. An exampleof a functionally designed material with a coaxially co-extruded architecture, knownin the ceramic field as a “fibrous monolith”, has elongated cells of a major (70-90vol.%) phase surrounded by cell boundaries of a minor (10-30 vol.%) phase. Avariety of strong-phase/weaker-phase combinations have been demonstrated,including Si3N4/BN, SiC/graphite, SiC/BN. Several wear resistant-phase/ductilephasecombinations have also been studied, including Diamond(Co)/WC(Co) for usein the petroleum drilling industry. The presentation will cover co-extrusionprocessing as a technology, applications that are being considered or are in productionfor most of the latter materials combinations, and a discussion of the functionalproperties that can be achieved using co-extrusion as a means to create functionallydesigned materials

    Notes: [Auszug] What you did to your uncle's grave was unforgivable. Your mother blamed herself, as always. You didn't know what you were doing, she said.

    Notes: [Auszug] Few would deny that many of the major problems currently facing humanity are social and economic in nature. From the apparent wave of religious fundamentalism sweeping the Islamic world (and parts of the Western world), to collective economic security, global warming and the great epidemics of our ...

    Notes: [Auszug] Parthenogenesis, the production of offspring without fertilization by a male, is rare in vertebrate species, which usually reproduce after fusion of male and female gametes. Here we use genetic fingerprinting to identify parthenogenetic offspring produced by two female Komodo dragons (Varanus ...

    Notes: [Auszug] Haploinsufficiency of Dll4, a vascular-specific Notch ligand, has shown that it is essential for embryonic vascular development and arteriogenesis. Mechanistically, it is unclear how the Dll4-mediated Notch pathway contributes to complex vascular processes that demand meticulous coordination ...
