Abstract

Purpose

This paper aims to present a simplified method to predict the pressure of the recess, no matter whether the tilt center coincides with the geometric center of the hydrostatic journal bearings.

Design/methodology/approach

To validate the effectiveness of the presented model, computational fluid dynamics (CFD) method and experimental method are performed in this study.

Findings

By comparing the CFD results and the experimental results, the pressure of the recess is related to the tilt direction, the tilt center, the width of the land and the circumferential angle of the land.

Originality/value

The mathematic model requires equivalent resistance of land edge – tilt position, tilt direction, tilt angle and the thickness of oil film instead of any digital iteration. Furthermore, a novel experimental apparatus including a circular hydrostatic bearing called ball bearing is designed to study the tilt effect produced by manufacturing error and offset load force on the pressure of the recess.

Abstract

Purpose

This paper attempts to provide novel approaches and tools for the analysis and measurement of stock bubbles.

Design/methodology/approach

The study is based on the perspective of a generalized virtual economy and the circulation process of accumulation strengthening and exclusion in the stock noise and is based on the symmetric chain model of the evolutionary game of combination of stock markets. Based on the stable ratio of the rational and irrational investors and the asymptotically stable strategy of the model in the two cases, the paper uses the improved classic model of noise trading (DSSW) to calculate the irrational bubbles on the Shanghai stock market.

Findings

The paper shows that the more irrational investors are, the higher the irrational bubbles are.

Practical implications

The method exposed in the paper can be used to study the formation mechanism of the stock market bubble, to analyze the impact of investors' behaviours, to measure the size of irrational bubbles and to put forward some reasonable policy recommendations and preventive measures.

Originality/value

The paper succeeds in pointing out a new stock market's irrational bubble calculation model on the basis of evolutionary game chain structure, and thus measures the size of the Shanghai stock market bubble and makes some tentative research and discussion about the evolution law of the stock market's irrational bubble.

Abstract

Purpose

As the world's largest developing country, China is relying on innovation to transform the pattern of economic growth; more and more attention has been paid to the construction of China's regional innovation system (RIS). This paper aims to establish a provincial evaluation index system for RIS construction level and that of construction condition and evaluate the innovation system construction level and construction condition of China's provinces by using grey fixed weight clustering.

Design/methodology/approach

This paper makes a comprehensive assessment of RIS by using grey fixed weight clustering.

Findings

The results show that the construction level of RIS is clearly associated with construction condition of RIS. In accordance with the results of the assessment, China's 31 provinces are classified into four typical types. Some relevant key measures to promote the RIS are suggested.

Originality/value

This paper establishes a new frame to evaluate RIS.

Abstract

Purpose

The purpose of this paper is to examine evolutionary processes of sectoral systems of innovation in China's catch‐up situation.

Design/methodology/approach

History event analysis method is used. The data that inform this paper come primarily from interviews carried out as a part of case studies of the innovations of China's car industry as well as public sources.

Findings

Market catch‐up of China's self‐owned brand cars expanded from low to high end market segment. Changes of the five building blocks of innovation system of China's car industry have driven the market catch‐up since the 1980s. The five building blocks are: market demand, industrial technology and knowledge base, institutional setting, industrial structure, firms' competences and strategy. China's car industry evolved through exploitation and exploration, which were affected by the five building blocks. The exploitation and exploration shaped the catch‐up way of China's car industry: from production localization to design localization and self‐owned brands. Exploration of the self‐owned brand group built on exploitation of the joint‐venture group.

Research limitations/implications

The findings are based on a single industry. Studies on more industries are needed to generalize the research results.

Practical implications

Increased understanding of how sectoral systems of innovation evolve will give managers and policy makers in the developing countries like China improved opportunities to formulate policies and management practices that can cultivate innovation capabilities in catch‐up.

Originality/value

The paper contributes to the research stream on sectoral systems of innovation by understanding building blocks and evolutionary processes at the base of change and growth in the catch‐up situation.

Abstract

Purpose

The purpose of this paper is to propose meta‐synthetic ideas and knowledge asset management approaches to build a comprehensive strategic framework for Beijing City in China.

Design/methodology/approach

Methods include a review of relevant literature in both English and Chinese, case studies of different types of support frameworks in the UK, the USA, Singapore and Hong Kong, formulation of a meta‐synthetic support framework for Beijing City, and justification of its application to policy development by various studies. Three stages of meta‐synthetic support frameworks are proposed.

Findings

The suggested meta‐synthetic support frameworks are highly appropriate for the optimisation of, and innovation in, management and services systems of government information resources. The proposed knowledge asset management approaches offer significant practical value in improving the competence and capabilities of service‐oriented government, providing a set of solutions to identified, urgent problems, including a joint administration system for creating value, a release and distribution management system for sharing and protecting value, and a licensing and authorisation management system for adding value.

Research limitations/implications

This paper focuses on the formulation of a theoretical support framework for the reuse of government information resources and the justification of its effectiveness to guide policy development at strategic level. Case studies of its application at operational level are ongoing and will be discussed in future papers.

Practical implications

The suggested meta‐synthetic support frameworks support the efficiency, effectiveness and economy of intelligent traffic administration, good governance of value‐added services based on government information resources, and intellectual activity around city travel and traffic. The study has wide implications for the improvement of service‐oriented government performance, public satisfaction and the image of government.

Originality/value

The paper presents the adaptation of meta‐synthetic ideas and knowledge asset management approaches to collaboration, optimisation, innovation and compliance management issues in the reuse of government information resources. The advantages of different types of support systems and frameworks are integrated as a coherent whole for a strategic framework of legal, regulatory and standards support to China and Beijing.

Abstract

Purpose

This paper aims to investigate the average daily consumption of cigarettes and its correlates, attitudes toward smoking, and suggestions for anti‐smoking measures in a sample of Chinese college student smokers.

Design/methodology/approach

A sample of 150 college student cigarette smokers in Baoding, a city near Beijing, filled out a questionnaire asking about their average daily consumption of cigarettes, attitude toward smoking and their opinions on how they might control their smoking behavior.

Findings

In total, 85.3 percent of the smoking students were males and 14.7 percent females, and males had started smoking earlier. However, and surprisingly, the average daily consumption among females was greater than among males (9.6 vs 5.6 cigarettes a day, p<0.01). Average daily cigarette consumption was significantly associated with perceived health condition (students who thought themselves in poorer health consumed more), perceived risk of cigarette smoking (but with those who thought it harmful actually consuming more than those who did not), frequency of offering cigarettes as gifts, and perceived enjoyment from smoking. The three most commonly reported measures which curbed smoking were friends' or classmates' suggestions, the urging of a boyfriend/girlfriend, and the urging of parents.

Practical implications

Findings in this paper underscore the importance of developing effective smoking cessation programs through gender‐specific approaches at post‐secondary educational institutions as well as coordinating anti‐smoking efforts at multiple levels of educational administration in China.

Originality/value

This paper adds to the few studies on Chinese college students' cigarette smoking practices and student smokers' attitudes toward cigarette smoking. It also reports for the first time possible effective anti‐smoking measures as suggested by the students themselves. The value of this study lies in the finding that cigarette smoking among highly educated individuals in China is on the rise and vigorous research on the smoking behavior of this group should be a high priority.

Abstract

Quality-Oriented Education (su zhi jiao yu) is a national education reform initiative that presents ongoing opportunities and challenges to schools, local bureaus of education, and the overall educational system in China today. This chapter seeks to gain insight into if and how Quality-Oriented Education, 10 years into its enactment, has taken root in practice. We posit that a reform agenda is best manifested through well-aligned and operable standards for school effectiveness. We introduce the policy-driven definition for school effectiveness and an evaluation framework depicting the intended focus of Quality-Oriented Education. Using an iterative and inductive process for content analysis, we compare the policy-driven framework with the coding results of a 2009 national inventory of actual school evaluation schemes in 91 Chinese school districts. Our review points out that the new mission of Quality-Oriented Education advocates educational equity, curriculum reform, and systemic support for school-based management. However, at the operational level, there are great variations in terms of content domain, focus, and function among school evaluation schemes with notable regional differences. Furthermore, schools are still caught between the existing system that measures school performance by achievement and the intended accountability scheme that calls for enhanced student ability. This chapter adds to the empirical foundation for the development of a new framework that not only captures the spirit of the national educational reform but also is informed of the developmental needs of schools in drastically different geo-economical and social conditions.

Abstract

Rural residential energy consumption accounts for 46.6% of total building-related energy consumption of China. In Northeast China, energy consumption for space heating represents a significant proportion of total rural residential energy consumption and has reached 100 million tce (tons of standard coal equivalent), or more than 60% of total household energy consumption. In terms of energy consumption per square meter of gross floor area, rural residential energy consumption for heating is more than that of cities (20kgce/m2). However, the average indoor temperature of most rural residence is below 10°C, much less than that in cities (18°C). Hence, it is an important task for Chinese energy saving and emission reduction to reduce rural residential energy consumption, while enhancing indoor thermal comfort at the same time.

Restricted by local technology and low economic level, rural residences currently have poor thermal insulation resulting in severe heat loss. This paper reports on research aimed at developing design strategies for improving thermal insulation properties of rural residences with appropriate technology. A field survey was conducted in six counties in severe cold areas of Northeast China, addressing the aspects of indoor and outdoor temperature, humidity, internal and external surface temperature of building envelop enclosure, and so on.

The survey data show the following:

1. Modern (after 2000) brick-cement rural residences perform much better than the traditional adobe clay houses and Tatou houses (a regional type of rural residence in Northeast China – see figure A) in overall thermal performance and indoor thermal comfort;

2. Among the traditional residential house types, adobe clay houses have better heat stability and thermal storage capacity than Tatou houses;

3. Applying an internal or external thermal insulation layer can greatly improve rural residential thermal insulation properties, and is an economical and efficient solution in rural areas;

4. In terms of roofing materials, tiled roofs show much better thermal insulation properties than thatch roofs;

5. Adopting passive solar techniques can form a transition space (greenhouse) against frigid temperatures, resulting in interior temperatures 5.91°C higher than the outside surroundings. It is evident that local passive solar room design offers significant heat preservation effects and lower cost ($12/m2), embodies the ecological wisdom of rural residents, and is therefore important to popularize.

The above experimental results can provide guidance in energy conservation design for both self-built residences and rural residences designed by architects. In addition, the results can also provide experimental data for energy-saving studies for rural residences in China.

Abstract

Urban planning is the blueprint for the development of urban construction and the basis for management of a city. The urban planning of China’s high-speed modernization has encountered many bottlenecks, and the gap between the daily living needs of residents and the urban planning objectives has attracted particular attention. Harmonious development between man and nature is necessary to build a harmonious society, and urban planning that is close to the needs of residents and more humanized has become the main goal of urbanization. In this paper, urban planning of Zhuhai City was studied for one year. Zhuhai focuses on building transport hub, industrial layout, and urban development in three major patterns. Many problems in the planning and management of Zhuhai City were encountered in the past, because the plans are only heavy concepts that ignore implementation and lack of comprehensive survey. Based on the concept of communication planning, the main features of the public participation in the urban planning model through modern mass media may be suitable for achieving the objectives and satisfying public needs. Urban planning and decision-making in Zhuhai City in recent years are evaluated by SWOT method. Future plans of Zhuhai City are discussed.
