Traditional Chinese Medicine (hereafter referred to as TCM) is made by Chinese herbal formulae and includes a ratio of pharmaceutical elements, which contain known health-enhancing functions. The trial process of the invention of TCM requires a lot of creative work and involves some risks....

Customer satisfaction with a service experience is often determined by several critical attributes. Prior studies have suggested that food, physical environment, and employee service impose an important effect on diners' satisfaction with restaurant services. Although much research has looked at...

Sentiment classification seeks to identify general attitude of a piece of text of comments or reviews on certain subject, be it positive or negative. Most existing researches on sentiment classification employ supervised learning approaches that rely on annotated data. However, sentiment is...

type="main" xml:id="jscm12070-abs-0001" <p>We introduce a new type of critical supplier—the nexus supplier—that becomes evident when we consider suppliers from a network perspective. The extant literature focuses on the importance of strategic suppliers and identifies strategic suppliers as...</p>

In this paper we establish a local precise large deviation result for sums Sn, n=1,2,... of independent and identically distributed random variables X1,X2,... with O-regularly varying densities f. The asymptotic behavior of the probability is comparable, for fixed T, with quantities or...

In studying temporally ordered rates of events, epidemiologists, demographers, and social scientists often find it useful to distinguish three different temporal dimensions, namely, age (age of the participants involved), time period (the calendar year or other temporal period for recording the...

This paper proposes a new way of modeling age, period, and cohort effects that improves substantively and methodologically on the conventional linear model. The linear model suffers from a well-known identification problem: If we assume an outcome of interest depends on the sum of an age effect,...

In this paper, we propose a novel measure that integrates both the concept of closed walks and clustering coefficients to replace the edge betweenness in the well-known divisive hierarchical clustering algorithm, the Girvan and Newman method (GN). The edges with the lowest value are removed...

Traditional resampling-based tests for homogeneity in covariance matrices across multiple groups resample residuals, that is, data centered by group means. These residuals do not share the same second moments when the null hypothesis is false, which makes them difficult to use in the setting of...
