Abstract

Purpose

Based on past studies on the bank effect, the purpose of this paper is to use hydrodynamic principles to simulate the overtaking and the head-on encounter phenomenon of two ships.

Design/methodology/approach

The ship model used in this study was established through a computer aided design (CAD) tool. Computational fluid dynamics (CFD) package was used to simulate the hydrodynamic interaction effect of the overtaking and the head-on encounter situation between two ships of different speeds. The conditions for simulation include such parameters as the speed of the ship model, the distance between the ships, and the navigation time.

Findings

A chart is also used to demonstrate the two ships ' distribution of flow field and pressure, and to continually compare the changes in the sway force and the yaw speed. A relationship diagram of the overtaking and the head-on encounter process is also established to serve as a reference in maritime science in terms of research regarding the complex fluid dynamics that occurs when ships are merged with the sea.

Originality/value

The application of CFD simulation results presented in this study for the ship-ship interaction support the following major conclusions: first, it is evident from the two analysis charts of angular velocity, and sway force that the cycle gradually becomes shorter with the decrease of speed of the V1 vessel during the overtaking and the head-on process; this phenomenon is most significant when the ship width is at 0.5B. Second, the ship-ship interaction increase significantly for a S2S value of 0.5B. Thus, the results indicate that the ship-ship interaction effects must be taken into consideration when performing ship handling maneuvers involving passing and meeting.

Abstract

Purpose

The purpose of this paper is to answer the question “will China overtake the USA in the space race?” This paper reviews China’s recent progress in aerospace while developing a wind theory of change to underline the geographic spread of various empires over the past thousand years, a topic studied by one of China’s most prestigious historians, Sima Qian, with a specific interest in 2,500 years of the rise and fall of Chinese kingdoms. Based on the wind theory, China is geared to overtake the USA in the twenty-first century space race. Historically, Chinese have always been fascinated with outer space, and it is felt by many Chinese that the USA, despite its current lead in the field, should work with China to explore outer space.

Design/methodology/approach

This paper introduces the philosophy and methodology of Sima Qian for Chinese management, in particular his analytical approach and drawing of lessons from past cases (dynasties) for managing the future which can be considered clearly reminiscent of the Harvard case approach. Evolving from this broad study of patterns by Sima Qian, a wind theory methodology is suggested using an overview of patterns over vast stretches of time, in this case from the Tang dynasty. Etymological analyses are embarked upon to illustrate how the ancient Chinese were interested in learning more about the outer space. Conceptual models are developed to map the current nascent space industry.

Findings

After outlining the current developments made by China in aerospace, the overall analysis suggests the following: based on the wind theory of change, China will overtake the USA even in race into space. Given their historical fascination with outer space, Chinese are likely to enter the business of space at the opportune time. When will that be? Most likely when appropriate technologies have been developed, in particular developing safe moon tours for tourists.

Practical implications

Suggests a futuristic look at the space industry that China can enter the market at the opportune time. With their long-term fascination with outer space, China may potentially be the largest market for those in space business.

Originality/value

Introduces a new idea of looking into the future possibilities as embedded in the wind theory of change: the geographical patterns in the rise and fall of empires. If this pattern holds, China will overtake the USA including in the race for outer space. For the first time, this paper draws the relevance of Sima Qian’s analytical, case-based methods for management.

Abstract

Purpose

This paper aims to argue for a China transmuting to fast overtake USA in innovation based on the extrapolation of past statistical trend. Case studies in self and co-innovation are provided so that the documentation of the dynamics of knowledge flows and a brain-linguistic explanation is given as to why, in the future, the Chinese are likely to lead in innovation.

Design/methodology/approach

This paper illustrates a multi-method approach in research for Chinese Management Studies. First, the sociological background of China is highlighted (Mao Zedong’s aphorism). Second, insights from OECD patent database are utilized. Third, the use of comparative research and development case-studies: self-innovation (Chinese) and co-innovation (contrasting Japanese versus French cooperation with Chinese). Fourth, is the inter-disciplinarily approach wherein the assimilating of knowledge is related to recent advances in brain research. Fifth, emphasizing the different levels in organizing for innovation: national (China), organizational (SOE), group processes and person-to-person, synapses within individual brains.

Findings

Statistical trend suggests that China is transforming and is on the path toward overtaking the USA in innovation. When will this happen? Using extrapolation as an indication, China may surpass the USA by the 50 per cent mark within the next decade. Insights into the processes of self-innovation and co-innovation are provided. Authors argue for a brain-linguistic explanation (Hebb, 1949) for further understanding why China will eventually lead ceteris paribus innovation, a function of the human brain.

Originality/value

This paper highlights on the basis of statistical trends (using OECD database) a rising, innovative China that is poised to overtake the USA in the near future. A major contribution is in providing insights of interactional processes required to foster innovation: self and co-innovation (comparing Japanese and French). The critical brain-linguistic role as the rationale as to why the Chinese are given a greater, more developed brain power that will eventually surpass the West in innovation.

Abstract

Describes coping strategies which make it possible to counteract and prevent driver stress. Driver stress is defined by increased aggression and alertness, a dislike of driving, and frustration and irritation elicited by interaction with other road‐users, in particular in relation to overtaking. It is associated with life stresses and health and emotional problems and affects the driver′s road safety.

Abstract

The mathematical models used to describe the dynamical behaviour of a group of closely-spaced road vehicles travelling in a single lane without overtaking are known as car-following models. This paper presents a novel car-following model, which differs from the traditional models by having an equilibrium solution that corresponds to consecutive vehicles having not only zero relative velocity, but also travelling at a certain desired distance apart. This new model is investigated using both numerical and analytical techniques. For many parameter values the equilibrium solution is stable to a periodic perturbation but, for certain parameter values, chaotic motion results. This shows that in congested traffic, even drivers attempting to follow a safe driving strategy, may find themselves driving in an unpredictable fashion.

Abstract

Purpose

The purpose of this paper is to identify the factors responsible for road traffic accidents among commercial commuter drivers in Lagos, Nigeria.

Design/methodology/approach

A total of 188 commercial drivers, driving 18‐seater mass transit buses in inter‐city highways were studied. Their accident records for the previous three years collected from Police records, Federal Road Safety Commission records, self‐administered questionnaires and observation of driving habits of the drivers. Their eye status were measured and data also collected from the Driver Union's Insurance Agency. A total of 25 human factor variables, identified as possible contributors to road traffic accidents were studied.

Findings

Six variables were found as possible significant contributors to road traffic accidents. They are old age, overtaking, overspeeding, religious affiliation, bad brake conditions and use of bad tyres. When the variables were subjected to two‐way interactions, 44 variable combinations were significant (p < 0.05) with R2 of 0.994 and residual error of 1.165.

Research limitations/implications

Accidents are not usually caused by single variables but by a combination of variables.

Originality/value

Apart from variables commonly found in the literature as possible causes of road traffic accidents, there may be some factors that may be peculiar to some countries like religious affiliation, belief in use of charms to protect drivers from accident and eye problems that are not identified because of lack of regular tests among others.

Abstract

Purpose

The paper aims to examine the state of the technology, media and telecommunications (TMT) sector at the global level from an occupier perspective. It provides a snapshot of activity in various geographic locations and looks at the major trends and underlying drivers. The paper suggests the implications of these trends for property with emphasis on opportunities for corporate occupiers.

Design/methodology/approach

The paper uses in-house data on property take up and internal as well as external sources on economic activity combined with documentary analysis and expert knowledge.

Findings

The paper suggests that the TMT sector could overtake the financial services sector as the main engine of global office take up. The paper also finds that the TMT sector is increasingly choosing to locate in central business districts as opposed to traditional out-of-town business parks.

Originality/value

This paper fulfils the need to understand some of the major shifts taking place within the TMT sector and make a connection between these changes with the property sector emphasizing on corporate occupation.
