Experimentation order with good properties for 2 k factorial designs

Randomizing the order of experimentation in a factorial design does not always achieve the desired effect of neutralizing the influence of unknown factors. In fact, with some very reasonable assumptions, an important proportion of random orders achieve the same degree of protection as that obtained by experimenting in the design matrix standard order. In addition, randomization can induce a large number of changes in factor levels and thus make experimentation expensive and difficult. De Leon et al. [Experimentation order in factorial designs with 8 or 16 runs, J. Appl. Stat. 32 (2005), pp. 297–313] proposed experimentation orders for designs with eight or 16 runs that combine an excellent level of protection against the influence of unknown factors, with the minimum number of changes in factor levels. This article presents a new methodology to obtain experimentation orders with the desired properties for designs with any number of runs.     

Do Flow Rates Respond Asymmetrically to Water Level? Evidence from the Edwards Aquifer

This research examines the time series relationship between the Comal Springs flow rate and the water level in the Edwards Aquifer (Well J-17). The empirical methodology utilizes threshold autoregression (TAR) and momentum-TAR models that allow for asymmetry in responses and adjustments to a disequilibrium in the long-run cointegrating relationship. Based on the results, an asymmetric error-correction model (AECM) is proposed to characterize the short-run and long-run dynamic relationship between spring flow and water level. The results have implications for the management of water resources, water demand, and ecosystems.

儒家演变的层面分析

区别儒家、儒学和儒教有积极的理论意义。儒家的演变是一个全方位的历史过程 :理论学说是其灵魂 ,政治制度是其保证 ,宗教神学是其表征。儒家与中国的传统文化形成和封建社会的发展有着相互制约的依存关系 ,研究它的立体演变模式对我们认识历史和现实有十分重要的启迪作用     

Biosphere Model for High Level Waste Repository

Method for environmental impact modeling involving uncertainty, overcoming the disadvantage of providing only one upper bound based on accumulated effects from all extreme events. This method provides a suite of upper and lower bounds based on any subset of such extreme events, to be chosen among by the decision maker.
