On group divisible response surface (GDRS) designs

In this paper some experimental situations are identified corresponding to which suitable response surface designs do not exist. A class of response surface designs is introduced to cope with these situations. Their analysis with and without blocking and methods of construction is discussed.     

Ordering pairwise comparison structures

Following an introduction to the merits of pairwise comparison methods, we present various ordering algorithms for complete binary preferential structures. These procedures generalize the well-known numbering algorithm to the intransitive case. A new form of independence of irrelevant alternatives is presented. Moreover, various other criteria and characterizations for these algorithms are presented. Aside from solving ranking problems and making explicit value criteria and structures of human preference, our algorithms are applicable to subjects such as task-sequencing and artificial intelligence projects.     

Ranked set sampling theory with selective probability vector

In this paper an estimator of the population mean is introduced by using the idea of selective probability vector and the optimization algorithm of linear programming to find the optimal solution of the selective probability vector under the condition of unbiasedness.     

ASYMPTOTIC DEFICIENCY OF THE JACKKNIFE ESTIMATOR

In this paper it is shown that the bias-adjusted maximum likelihood estimator (MLE) is asymptotically equivalent to the jackknife estimator in the variance up to the order n^-1 and the asymptotic deficiency of the jackknife estimator relative to the bias-adjusted MLE is equal to zero.     

Another characterization of the weibull distribution

A necessary and sufficient condition is given that an absolutely continuous positive random variable follow a Weibull distribution. The condition Is based on some functions of order statistics.     

论英语语言体系中的“啄序”现象

对于英语语言体系内部的划分,传统的地理政治学模式并不能准确地反映英语语言体系内部实际存在的复杂状况.以南非英语和非洲英语之间的关系为例,英语语言体系中的"啄序"--强弱排列顺序现象有其深层原因.应树立维护语言共核、尊重地域特色的语言教育观.

Revolution: Refining Its Defining

Definitions of revolution have strongly influenced theorization about it. We argue here that revolution is a highly variable phenomenon. Rigid definitions of revolution do not allow for theorizing which explains this variability. Revolution can occur to various degrees along various dimensions. These include the political, international, economic, cultural, ethnic, and gender dimensions. Revolutions do not necessarily affect all these dimensions equally. Revolutions that have led to great change along some of these dimensions have also led to little or no change along others. We further argue that an understanding of revolution requires an understanding of what maintains social order.     

The State and the Associational Order of the Economy: The Institutionalization of Cartels and Trade Associations in 1931–45 Japan

The existing literature on the impact of the state on the associational order has emphasized the state's concern on the implications of the associational order to the public goods and the role of the associational order as a policy tool of the state. However, few studies have investigated what particular characters of the state shape the pattern of the associational order. Through a historical analysis, this study highlights three important factors related to the state that contributed to the the rise of the associational order in Japan during the Great Depression and World War II. First, the shift of the state preference from protecting the liberties of private enterprises toward maintaining political stability in economic crisis and controlling resource allocation in war was the ultimate driving force behind the rise of associational order. Second, the constitutional order of the Japanese state, which involves not only the organization, composition, powers, and limitation of the state's executive, legislative, and jurisdictional branches, but also the people's liberties defined by the constitution, was strongly influenced by the continental legal tradition. This structurally shaped the Japanese pattern of the associational order. Third, the institutionalized legal and economic beliefs of property rights provided ideological support to the rise of the associational order.     

Modeling low birth weights using threshold regression: results for U. S. birth data

Babies born live under 2,500 g or with a gestational age under 37 weeks are often inadequately developed and have elevated risks of infant mortality, congenital malformations, mental retardation, and other physical and neurological impairments. In this paper, we model birth weight as a first hitting time (FHT) of a birthing boundary in a Wiener process representing fetal development. We associate the parameters of the process and boundary with covariates describing maternal characteristics and the birthing environment using a relatively new regression methodology called threshold regression. Two FHT models for birth weight are developed. One is a mixture model and the other a competing risks model. These models are tested in a case demonstration using a 4%-systematic sample of the more than four million live births in the United States in 2002. An extensive data set for these births was provided by the National Center for Health Statistics. The focus of this paper is on the conceptual framework, models and methodology. A full empirical study is deferred to a later occasion.
