Generalized confidence intervals for the process capability indices in general random effect model with balanced data

In this paper, we consider the interval estimation problem on the process capability indices in general random effect model with balanced data. The confidence intervals for three commonly used process capability indices are developed by using the concept of generalized confidence interval. Furthermore, some simulation results on the coverage probability and expected value of the generalized lower confidence limits are reported. The simulation results indicate that the proposed confidence intervals do provide quite satisfactory coverage probabilities.     

“Heaven”and “Man”under the Reconstitution of the Confucianism —— from “Heaven and Man Being Related”to “Heaven and Man Being in One”

Through analysis of the relationship between heaven and man and the development of the ideology in the developing process from the pre- Qin Confucianism, the cosmology Confucianism of the Han Dynasty to the formation of the Confucian School of idealist philosophy of the Song and Ming dynasties, this paper attempts to explore the Confucianism ideology from social structure, cultural integration and environmental change and so on, so as to points out that Confucianism does not collapse with the disintegration of the social structure; instead,it realizes self- reconstruction and renovation.     

Effects of human-related disturbance on breeding success of urban and non-urban blue tits (<Emphasis Type="Italic">Cyanistes caeruleus</Emphasis>)

There is a need to study the effects of urbanization on wildlife in order to understand the ecological implications of increasing urbanization and find out how to reduce its threats to biodiversity. The blue tit evolved as a forest species and prefers deciduous and mixed forests, whereas its nesting in urban habitats is a more recent phenomenon. Our long-term study of blue tit populations has been conducted in two habitats: an urban parkland (frequently visited by people) and a deciduous forest outside of the city. Using linear mixed modeling, we revealed that a relationship of blue tit breeding success (and the number of fledglings) with thermal conditions in May differed between the urban parkland and the forest. While the relationship was positive in the forest, it was negative in the parkland. In addition, breeding success in the parkland increased with increasing number of rainy days in May. We argue that the main possible reason for such patterns is human activity in the parkland, which interferes with tit parental care, especially the regular feeding of nestlings, whereas it is evidently associated with weather conditions. Human disturbance in the forest is likely to be negligible.

Integrative Analysis of Cancer Diagnosis Studies with Composite Penalization

In cancer diagnosis studies, high‐throughput gene profiling has been extensively conducted, searching for genes whose expressions may serve as markers. Data generated from such studies have the ‘large d, small n’ feature, with the number of genes profiled much larger than the sample size. Penalization has been extensively adopted for simultaneous estimation and marker selection. Because of small sample sizes, markers identified from the analysis of single data sets can be unsatisfactory. A cost‐effective remedy is to conduct integrative analysis of multiple heterogeneous data sets. In this article, we investigate composite penalization methods for estimation and marker selection in integrative analysis. The proposed methods use the minimax concave penalty (MCP) as the outer penalty. Under the homogeneity model, the ridge penalty is adopted as the inner penalty. Under the heterogeneity model, the Lasso penalty and MCP are adopted as the inner penalty. Effective computational algorithms based on coordinate descent are developed. Numerical studies, including simulation and analysis of practical cancer data sets, show satisfactory performance of the proposed methods.     

A plug-in the number of knots selector for polynomial spline regression

A plug-in the number of interior knots (NIKs) selector is proposed for polynomial spline estimation in nonparametric regression. The existence and properties of the optimal NIKs for spline regression are established by minimising the weighted mean integrated squared error. We obtain plug-in formulae for the optimal NIKs based on the theoretical results of asymptotic optimality, and develop strategies for choosing the NIKs of the spline estimator. The proposed NIKs selection method is tested on our simulated data with quite satisfactory performance, and is illustrated by analysing a fossil data set.     

Dynamic work hour optimization for casual workers

An original online problem named the work-break problem is proposed to optimize the work hours of casual workers. The algorithm for our problem has to answer for a casual worker about when he should have a break for his efficiency declines with the growing duration of current work period. We consider the online uncertainty of the work efficiency and present a periodic algorithm for the problem. Then our algorithm is proved to be 2-competitive by a novel form of competitive analysis.

Sensorial Place-Making in Ethnic Minority Areas: The Consumption of Forest Puer Tea in Contemporary China

This article examines sensorial place-making through analysing the taste and other sensory experiences of forest Puer tea in its consumption among the urban middle class in mainland China. In the process of creating the ‘terroir’ of forest Puer tea, sensorial experience has been frequently linked to its place of origin. I argue that ethnic minorities who cultivate the tea play a vital part in the imagination of the tea's terroir. Trips by consumers to the mountains where the tea is cultivated, which aim at facilitating a ‘full experience’ of the tea and its culture, have generated a special pattern of interactions between the urban middle class who consume the tea and the ethnic minorities who cultivate it. The consumption of Puer tea, which brings about social imaginary and transcendent economic value, has become a driving force for producing the locality of ethnic minority areas.
