Purpose – The purpose of this paper is to introduce a new similarity method to gauge the differences between two subject hierarchical structures. Design/methodology/approach – In the proposed similarity measure, nodes on two hierarchical structures are projected onto a two-dimensional space,...

Urban national parks were designed in the 1970s to bring nature and recreational opportunities to socio-economically disadvantaged communities in the USA. Using the theoretical frame of environmental justice, this paper discusses findings of a recent survey of visitors to Los Angeles' Santa...

Capital acquisition is one of the most challenging and important issues facing small firms. This paper examines issues related to the acquisition of capital by niche agricultural producers. Niche agricultural producers face greater capital acquisition challenges than traditional small firms...

The discordancy test for multiple outliers is complicated by problems of masking and swamping. The key to the settlement of the question lies in the determination of k , i.e. the number of 'contaminants' in a sample. Great efforts have been made to solve this problem in recent years, but no...

T = \[x + … + x ]/ Sigma x (T*= \[x + … + x ] Sigma x ) is the max k (n- k+ 1 ) (n) i k ( 1 ) (k) i imum likelihood ratio test statistic for k upper ( lower ) outliers in an exponential sample x , …, x . The null distributions of T for k= 1,2 were given by Fisher and by Kimber 1 n k and...

This paper looks closely at a key hypothesis of Stephen Hymer, namely that a small number of giant corporations would soon dominate each sector of the global economy. The article shows that, although the nature of the large corporation has changed profoundly, Hymer's basic insight has proven...

This paper illustrates application of Bayesian inference to quantile regression. Bayesian inference regards unknown parameters as random variables, and we describe an MCMC algorithm to estimate the posterior densities of quantile regression parameters. Parameter uncertainty is taken into account...
