This study aims to optimize the manufacturing process to improve the manufacturing quality, costs and delivering time with the help of multiscale multiphysics modelling and simulation. Multiscale multiphysics-based modelling and simulations are receiving more and more interest by research community and the industry particularly in the context of increasing demands for manufacturing high precision complex products and understanding the intrinsic complexity in associated manufacturing processes.
In this paper, some modelling and analysis techniques using multiscale multiphysics modelling are presented and discussed.
Furthermore, the possibility of adopting the multiscale multiphysics modelling and simulation to develop the virtual machining system is evaluated, and further supported with an industrial case study on abrasive flow machining (AFM) of integrally bladed rotors using the techniques and system developed.
With the development of multiscale multiphysics-based modelling and simulation, it will enable effective and efficient optimisation of manufacturing processes and further improvement of manufacturing quality, costs, delivery time and the overall competitiveness.

FastSLAM is a popular method to solve the problem of simultaneous localization and mapping (SLAM). However, when the number of landmarks present in real environments increases, there are excessive comparisons of the measurement with all the existing landmarks in each particle. As a result, the execution speed will be too slow to achieve the objective of real-time navigation. Thus, this paper aims to improve the computational efficiency and estimation accuracy of conventional SLAM algorithms.
As an attempt to solve this problem, this paper presents a computationally efficient SLAM (CESLAM) algorithm, where odometer information is considered for updating the robot’s pose in particles. When a measurement has a maximum likelihood with the known landmark in the particle, the particle state is updated before updating the landmark estimates.
Simulation results show that the proposed CESLAM can overcome the problem of heavy computational burden while improving the accuracy of localization and mapping building. To practically evaluate the performance of the proposed method, a Pioneer 3-DX robot with a Kinect sensor is used to develop an RGB-D-based computationally efficient visual SLAM (CEVSLAM) based on Speeded-Up Robust Features (SURF). Experimental results confirm that the proposed CEVSLAM system is capable of successfully estimating the robot pose and building the map with satisfactory accuracy.
The proposed CESLAM algorithm overcomes the problem of the time-consuming process because of unnecessary comparisons in existing FastSLAM algorithms. Simulations show that accuracy of robot pose and landmark estimation is greatly improved by the CESLAM. Combining CESLAM and SURF, the authors establish a CEVSLAM to significantly improve the estimation accuracy and computational efficiency. Practical experiments by using a Kinect visual sensor show that the variance and average error by using the proposed CEVSLAM are smaller than those by using the other visual SLAM algorithms.

This chapter explores cultural factors that influence the propensity to blow-the-whistle in China, Taiwan, Russia, and the United States. This study found that culture and traditions have strong impact on the propensity of whistleblowing. This research analyzed 1,541 working adults in China, Taiwan, Russia, and the United States. Statistical analysis of self-developed questionnaires reveal that: (a) Americans have a greater disposition to engage in whistleblowing than Chinese, Taiwanese, and Russian; (b) Americans have a smallest level of fear of retaliation to whistleblowers than Chinese, Taiwanese, and Russian; (c) the intention of Chinese, American, and Taiwanese to whistle-blow is influenced to a greater degree by position of wrongdoers than that of Russian; and (d) guanxi (personal relationships or networks) has a greater effect on the propensity to whistle-blow for Chinese and Taiwanese than for Americans and Russian. Auditors and managers need to be aware that employees in different cultures respond differently to factors that influence whistleblowing activities. The results of this study will help auditors and managers better assess risk and the effectiveness of internal controls and ethical standards.

Cosmopolitanism represents a complex, multilevel, multilayer phenomenon manifested in a variety of social spheres, including moral, political, social, and cultural. Yet, despite its prominence in other disciplines, cosmopolitanism has received relatively scant attention in international management research. Furthermore, the understanding of cosmopolitanism as an ever-present social condition in which individuals are embedded lags significantly behind.
In this chapter, we develop a conceptual framework for cosmopolitanism as an individual-level phenomenon situated at the intersection of the moral, political, and sociocultural perspectives. The framework explicates the interrelations between macrolevel dynamics and individual experiences in a globalized world. We conceptualize cosmopolitanism as an individual disposition manifested and enacted through identities, attitudes, and practices. We also highlight the diversity of individuals who can be considered cosmopolitans, including those who may not possess the classic cosmopolitan CV. Finally, the chapter explores the implications of cosmopolitanism for global organizations and global leadership.
China is known for its culture of uniformity and conformity. Such a cultural tradition was reinforced in the socialist system that was established in 1949. This was significant in education, which then became an important and instrumental part of the planned economy. During the high time of the planned economy, the entire nation was but one gigantic production unit under one central plan. People's lives are therefore also highly coordinated according to a general national plan. Products from all over the country were collected by the central government, and resources over the entire country were allocated by the central government. Therefore by design, there was not disparity, but then there was also no diversity.
To me, diversity is a concept that evolves over time. I was born in Kunming, China. It was only when I started my doctoral study in London, I realized that diversity is so foreign to my culture. I left Kunming, which is in a province of the greatest ethnic diversity, when I was 1 year old and returned to Chinese societies where the Hans, the majority, shape the culture. When I was five, I moved from Shanghai to Hong Kong where I received my entire schooling.

Identifies several features in East Asian schools which coincide with commonly recognized characteristics of effective schools in the Western literature: community support, teacher professionalism, attention to quality and high expectations. Attributes this to the East Asian culture and discusses three major dimensions of the East Asian culture: the individual‐community dimension, the effort‐ability dichotomy and the holistic‐analytic tendency in analyses. Traces the origin of such cultural dimensions in the ancient literature and explores the implications of such cultural dimensions in school management. Briefly highlights two major challenges to the adoption of an effective schooling system in East Asia.

Provides a review of the position of women in management in a number of countries. Describes how in almost all countries, management positions are dominated by men. Concludes that, although many similarities were found in women’s work experience across cultures, cultural factors accounted for the unique experiences of women in a given country.

Over the last decade, scholars extensively discuss talent management phenomenon in various country contexts paying much attention to different exogenous and endogenous factors influencing talent management systems and practices and their relationships with other organizational processes. In this chapter we particularly talk about the peculiarities of talent management in Brazil and Russia and explore the potential impact key management practices aimed at attracting, developing and retaining high potentials and high performers have on the development of firms’ absorptive capacity. We argue that for Brazilian and Russian firms “crossverging” context-specific talent management practices play a key role in the acquisition, assimilation, transformation, and exploitation of external and internal valuable knowledge, thus becoming one of the main drivers of organizational performance and competitive advantage.

This paper investigates the influence of modernisation on the moral judgements of 211 managers residing in the People’s Republic of China, based on their responses to a series of vignettes depicting potentially unethical behaviour in organisations. Results suggest that there is a significant association between moral judgement and modernisation. Managers from the more industrialised and economically advanced provinces in China gave harsher moral judgements, that is, higher ratings of unethicality, in five out of six vignettes. The study reported in this paper offers valueable insights into the nature of value and attitude change, or “convergence”, as China adopts elements of a more modernised market style economy.
