We study a solution of long polyanions (PA) with shorter polycations (PC) and focus on the role of Coulomb interaction. A good example is solutions of DNA and PC which are widely studied for gene therapy. In the solution, each PA attracts many PCs to form a complex. When the ratio of total...

In this paper, we establish a central limit theorem for a large class of general supercritical superprocesses with spatially dependent branching mechanisms satisfying a second moment condition. This central limit theorem generalizes and unifies all the central limit theorems obtained recently in...

Purpose – This paper aims to present a new friction-stir-weld robot for large-scale complex surface structures, which has high stiffness and good flexibility. Design/methodology/approach – The robot system is designed according to manufacturability of large aluminum products in aeronautic...

Purpose This review aims to discuss concepts and theories from cognitive psychology, identifies tourism studies applying them and discusses key areas for future research. The paper aims to demonstrate the usefulness of cognitive psychology for understanding why tourists and particularly pleasure...

We propose a new model of multi-product firms in international trade, where firms choose their product mix based on the products’ attractiveness and endogenous competition. The model is motivated by two novel stylized facts using Danish manufacturing data, which demonstrate the importance of...

In der Arbeit wurde eine Methode für eine kulturübergreifende Vergleichsstudie zwischen China und dem Westen erarbeitet. Diese Methode ermöglicht Unternehmensentwicklung in China aus dem eignen historischen Zusammenhang zu verstehen, statt nur aus einem rein theoretischen Blickwinkel. Weil...

Purpose: The purpose of this paper is to investigate the internal control disclosure (ICDISC) practices in South Asia and compare those disclosure practices across enforced setting (India) versus comply or explain setting (Pakistan and Bangladesh). Further, whether the audit firm size moderates...

Purpose: This study aims to revisit the corporate social and environmental disclosure (CSED) practices of Pakistani companies using unique CSED index which measures the CSED through three dimensions such as theme, news type and nature of information. In addition, the effect of board...
