Abstract

Considers the problem of improving the performance of Web access by proposing a reconstruction of the internal link structure of a Web site in order to match the quality of the pages (measured in terms of their link importance in the Web space – global ranking) with the popularity of the pages (measured in terms of their importance recognized by Web users – local metrics). Provides a set of simple algorithms for local reorganization of a Web site, which results in improving users’ access to quality pages in an easy and quick way.

Abstract

Purpose

The purpose of this paper is the development of a robust numerical scheme for fluid flow simulations in complex domains with open boundaries.

Design/methodology/approach

A modified pressure correction algorithm is presented. The proposed modifications are derived through a step-by-step analysis of the importance of mass continuity enforcement in pressure correction methods, the boundary conditions of the pressure correction equation and the special nature of open boundaries.

Findings

The algorithm is validated by performing steady state laminar flow simulations in two backward facing step geometries with progressively truncated outlet channels. The efficiency of the methodology is demonstrated by simulating the pulsatile flow field in a patient specific iliac bifurcation reconstructed by medical imaging data.

Originality/value

The proposed numerical scheme provides accurate and mass conserving solutions in complex domains with open boundaries. The proposed methodology may be directly implemented in any computational domain without any prerequisites regarding the location or type of domain boundaries.

Abstract

Purpose

This study aims to explore the impacts of the knowledge structure of CEO on corporate innovation strategy in the background of China’s national policy of innovation-driven development.

Design/methodology/approach

Regression analysis is used to test the direct effects and the moderating roles of financial and power incentives. It screens 685 listed companies from Chinese stock market, with the time window from 2016 to 2018.

Findings

CEO’s knowledge breadth has a significant impact on innovation strategy, but the moderating effects of power and financial incentives are not significant. CEO’s knowledge depth is negatively correlated to corporate innovation strategy; moreover, power incentive significantly strengthens the relationship, whereas financial incentive significantly weakens it.

Research limitations/implications

Firms are suggested to optimize CEO knowledge structure and organizational incentive system for better implementing innovation-driven development strategy.

Originality/value

It is beneficial to the exploration of the micro-mechanism that enables corporate innovation strategy. Scholars may gain additional insights into the strategic management of corporate innovation from the perspective of CEO’s knowledge structure.
