Design and Analysis of Integrated Manufacturing Systems is a fresh look at manufacturing from a systems point of view. This collection of papers from a symposium sponsored by the National Academy of ...Engineering explores the need for new technologies, the more effective use of new tools of analysis, and the improved integration of all elements of manufacturing operations, including machines, information, and humans. It is one of the few volumes to include detailed proposals for research that match the needs of industry.
The Madisonian approach to institutional design, as set forth in The Federalist Papers, is examined from the point of view of leading theorists of the "public choice" school who see themselves as the ...political heirs of that earlier legacy.Bernard Grofman taught a course on representation in which the readings included both the Federalist Papers and Buchanan and Tullock s Calculus of Consent. In teaching that course (and, as he writes, forcing himself to reread the Federalist carefully for the first time since his own graduate student days), his admiration for its authors, already high, grew even higher. Convinced that theorists of the public choice school were the natural heirs to the Federalist legacy, he was inspired to invite other scholars to contribute to this volume of articles. The new institutionalists of the public choice school are, Grofman says, the natural heirs to Madisonian political theory, but the features of Madisonian theory are almost entirely absent from the public choice literature: the role of deliberation and rational persuasion, a concern for justice and the search for the public good, and a respect for civic virtue and civic education. In that vision, institutions really do matter. Contemporary theorists of the new institutionalism have at their disposal powerful analytic tools which can be used to reformulate and clarify classic issues in political theory. A leading traditional political theorist wrote that public choice modelers needed to rediscover the Constitution (Mansfield, 1987, 41). This volume is intended as a first start in that direction.
Exploring the full range of Novalis's (the pen name of the German poet and philosopher Friedrich von Hardenberg) work, von Molnar shows how he dealt, in theory and practice, with a central issue in ...Romanticism-the emerging concept of the autonomous self and its relation.
A steady state, spherically symmetric, magnetohydrodynamic model of the Crab nebula is constructed. A highly relativistic positronic pulsar wind is terminated by a strong MHD shock that decelerates ...the flow and increases its pressure to match boundary conditions imposed by the recently discovered supernova remnant that surrounds the nebula. If the magnetic luminosity of the pulsar wind upstream of the shock is about 0.3 percent of its particle luminosity, the pressure and velocity boundary conditions imposed by the remnant place the shock where it is inferred to be: near the outer boundary of an underluminous region observed to surround the pulsar. It is necessary to include the weak magnetization of the wind to satisfy the boundary conditions and to calculate the regular synchrotron radiation self-consistently.
The Bright Quasar Survey (BQS) consisting of 114 objects to an average limiting magnitude B = 16.16 over an area of 10,714 sq deg is presented. There are 92 quasars with M(B) less than -23 in the ...sample. The BQS and complete samples from published surveys are used to derive models of the statistical evolution of quasars. The increase of space density with redshift depends strongly on absolute luminosity, being close to zero for low-luminosity quasars. Detailed predictions are given for the distribution of redshifts and magnitudes and for the total counts based on the evolution models.
Modeling the choice among a discrete set of recreation alternatives is driven by the possible patterns of substitution among sites. Researchers typically assume that the individual's choice set is ...the same as the set of alternatives included in the recreation survey instrument. Our endogenous choice set model is a generalization of the standard multinomial logit random utility model which allows for the possibility of heterogeneous choice sets that are endogenously determined in the model. Using two examples, we show that parameter and compensating variation estimates differ greatly between the endogenous choice set model and the traditional logit model.
20094/25637. C 18. Espacios naturales protegidos. El especialista enfatiza que para que este capítulo sea enteramente comprendido, resulta imprescindible iniciarlo explicitando la interpretación que ...de él se da al concepto de áreas o espacios protegidos señalando, a su vez, que se usará este término en su denominación más universal, para nuestros espacios protegidos en Venezuela. Áreas Bajo Régimen de Administración Especial: ABRAE'S que es como se los denomina en la legislación y gestión ambiental venezolana. Gondelles en 1992 las definió como: espacios geográficos, sitios y elementos del medio con características biofísicas singulares o con otras cualidades o potencialidades en lo socio-cultural, las cuales ameritan recibir del estado una protección efectiva y permanente bajo un régimen de administración sui-generis que garantice la integridad física sin merma de sus valores, mediante una utilización acorde con esos objetivos y una protección y manejo adecuado a esas características. Estas áreas se consideran singulares por el hecho de no ser comunes y porque sus cualidades son de particular interés para la ciencia y para la sociedad en general. A través de la Ventana 3. Cronología de los aspectos relevantes de la gestión ambiental para las Áreas Protegidas de Venezuela, se describen las acciones que se han venido desarrollando en el tiempo en esas áreas. A través de la Ventana 4, se sintetizan los principales resultados del 5. Congreso Mundial de Áreas Protegidas, realizado en Durban-Sudáfrica 2003. En cuanto al nivel de cubrimiento territorial alcanzado por el Sistema de Parques Nacionales, este se analiza por Provincias Fisiográficas. Se detalla igualmente el nivel de cubrimiento y protección en cada una de las 16 Regiones Fisiográficas del país. Se ilustra sobre los componentes principales de la planificación en Áreas Protegidas en Venezuela y del modelo de gestión estratégica para esas áreas. El autor presenta la superficie que ocupa cada una de las siguientes Provincias Fisiográficas del país: -Plataforma continental (4,30%) incluye islas y llanuras costeras; -Cordillera de la Costa (13,56%); -Valles y Serranías (3,66%), principalmente en Falcón-Lara-Yaracuy; -Cordillera de los Andes (27,40%); -Llanos (7,13%); -Guayana Venezolana (22,51%) para un total de 97.119,15 kilómetros cuadrados.
