Abstract

Purpose

The aim of this study is to present a novel approach based on semantic fingerprinting and a clustering algorithm called density-based spatial clustering of applications with noise (DBSCAN), which can be used to convert investor records into 128-bit semantic fingerprints. Inventor disambiguation is a method used to discover a unique set of underlying inventors and map a set of patents to their corresponding inventors. Resolving the ambiguities between inventors is necessary to improve the quality of the patent database and to ensure accurate entity-level analysis. Most existing methods are based on machine learning and, while they often show good performance, this comes at the cost of time, computational power and storage space.

Design/methodology/approach

Using DBSCAN, the meta and textual data in inventor records are converted into 128-bit semantic fingerprints. However, rather than using a string comparison or cosine similarity to calculate the distance between pair-wise fingerprint records, a binary number comparison function was used in DBSCAN. DBSCAN then clusters the inventor records based on this distance to disambiguate inventor names.

Findings

Experiments conducted on the PatentsView campaign database of the United States Patent and Trademark Office show that this method disambiguates inventor names with recall greater than 99 per cent in less time and with substantially smaller storage requirement.

Research limitations/implications

A better semantic fingerprint algorithm and a better distance function may improve precision. Setting of different clustering parameters for each block or other clustering algorithms will be considered to improve the accuracy of the disambiguation results even further.

Originality/value

Compared with the existing methods, the proposed method does not rely on feature selection and complex feature comparison computation. Most importantly, running time and storage requirements are drastically reduced.

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

Purpose

The goal of the special issue is to review current cigarette smoking trends in China; this article aims to provide an overview of the main themes of the special issue.

Design/methodology/approach

The instruments for data collection of the five studies in this special issue are surveys. One study used a random sampling method, one used an intercept survey method, and three used a convenience sampling method.

Findings

Highlights of the findings include: among the 677 physicians surveyed, 31.6 percent of the men and 0.9 percent of the women were current smokers; 79.2 percent of the cigarette users reported smoking on duty; 15 percent of the cigarette users smoked in front of patients. Sixty‐one percent of the physicians often advised patients to quit smoking. Two factors significantly influenced a physician's anti‐smoking frequencies: whether they were smokers themselves and whether they had received training on helping patients to quit smoking. About half of the 269 patients surveyed reported seeing someone smoking inside the hospital, and 22.3 percent had seen physicians and/or nurses smoking. Among the 758 medical students surveyed, 26.5 percent of males and 1.6 percent of females had smoked in the previous 30 days.

Practical implications

The exclusive coverage of a western journal on cigarette smoking in China can draw the attention of Chinese and western scholars in the field, as well as the attention of the Chinese Ministry of Health, to this major national problem. This attention should help to advance anti‐smoking educational campaigns in China.

Originality/value

This is the first special issue by a western academic journal on cigarette smoking in China, where rates are far higher than in most other parts of the world, and are a major health concern. Two studies have large sample sizes and all five studies have high response rates.

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

Purpose

This study aims to outline the current challenges in ultrasonic additive manufacturing (AM). AM has revolutionized manufacturing and offers possible solutions when conventional techniques reach technological boundaries. Ultrasonic additive manufacturing (UAM) uses mechanical vibrations to join similar or dissimilar metals in three-dimensional assemblies. This hybrid fabrication method got attention due to minimum scrap and near-net-shape products.

Design/methodology/approach

This paper reviews significant UAM areas in process parameters such as pressure force, amplitude, weld speed and temperature. These process parameters used in different studies by researchers are compared and presented in tabular form. UAM process improvements and understanding of microstructures have been reported. This review paper also enlightens current challenges in the UAM process, process improvement methods such as heat treatment methods, foil-to-foil overlap and sonotrode surface roughness to increase the bond quality of welded parts.

Findings

Results showed that UAM could solve various problems and produce net shape products. It is concluded that process parameters such as pressure, weld speed, amplitude and temperature greatly influence weld quality by UAM. Post-weld heat treatment methods have been recommended to optimize the mechanical strength of ultrasonically welded joints process parameters. It has been found that the tension force is vital for the deformation of the pre-machined structures and for the elongation of the foil during UAM bonding. It is recommended to critically investigate the mechanical properties of welded parts with standard test procedures.

Originality/value

This study compiles relevant research and findings in UAM. The recent progress in UAM is presented in terms of material type, process parameters and process improvement, along with key findings of the particular investigation. The original contribution of this paper is to identify the research gaps in the process parameters of ultrasonic consolidation.

Abstract

Purpose

The purpose of this paper is to study the evolution of Chinese industrial relations after the market reform of 1978, while basing its arguments and conclusion on analysis of the interactions of key actors in the labour arena in China. The significant phenomena in the evolution of industrial relations are the coming of transnational capital and the emergence of self‐organising protests by migrant workers.

Design/methodology/approach

The paper uses a case study approach.

Findings

The Labour Contract Law and the local political economy experience strong effects from TNCs and other business players. Meanwhile, globalisation has introduced the civil society movement to China, which has given rise to an increasing number of NGOs working for labour rights. Tight financial and technical connections between grassroots NGOs and international donor organisations make it possible for bottom‐up labour activities to counteract the unilateral influence of the state and market over the Chinese workforce. Since the ACFTU, the official trade union umbrella, has many institutional constraints to undertake a thorough transition towards labour in the near future, workers' representation is diversified.

Originality/value

One implication for further theoretical studies is that tripartism cannot fully disclose the reality of Chinese labour, and that labour representation derives from both unions and self‐organisation of workers, such as NGOs, which opens more room for the entrenchment of the grassroots labour movement to sustain the balance of power among the state, ACFTU, firms, international market forces and individual workers in the long term.
