Purpose – This paper aims to investigate whether an employee reports an accurate view of the relative performance level of the organisation for which they work. Design/methodology/approach – Utilizes a survey of 2,517 senior managers, managers and team leaders from 120 different...

Purpose – The purpose of this paper is to explore the underlying reasons why providing process improvement training, by itself, may not be sufficient to achieve the desired outcome of improved processes; and to attempt a conceptual framework of management training for more effective...

Partially linear models are extended linear models where one covariate is nonparametric, which is a good balance between flexibility and parsimony. The partially linear stochastic model with heteroscedastic errors is considered, where the nonparametric part can act as a trend. The estimators of...

Let {ξi,j} and {ηi,j}(1≤i≤n,1≤j≤m) be standard Gaussian random variables. Gordon’s inequality says that if E(ξi,jξi,k)≥E(ηi,jηi,k) for 1≤i≤n,1≤j,k≤m, and E(ξi,jξl,k)≤E(ηi,jηl,k) for 1≤i≠l≤n,1≤j,k≤m, the lower bound...

In view of the actual condition of the insurance company, a multi-risk model is proposed. The lower bound for the sums of long-tailed claims in this model is given. The proof method is based on the results of precise large deviation for long-tailed distributions.

In view of the actual condition of the insurance company, a multi-risk model is proposed. The lower and upper bounds for the sums of subexponential claims in this model are given. The proof method is based on the results of the total claim amount under subexponential class.

Consider two exit probabilities of the Bessel process B(s) where hi(x),i=1,2 are reversible nondecreasing lower semi-continuous convex functions on [0,[infinity]) with hi(0),i=1,2 finite. W1(s) and W2(s) are independent standard Brownian motions and independent of {B(s)[set membership,...
