Abstract
Purpose
The purpose of this paper is to assess the performance of competing methods and model selection, which are non‐trivial issues given the financial implications. Researchers have adopted various methods including statistical models and machine learning methods such as neural networks to assist decision making in direct marketing. However, due to the different performance criteria and validation techniques currently in practice, comparing different methods is often not straightforward.
Design/methodology/approach
This study compares the performance of neural networks with that of classification and regression tree, latent class models and logistic regression using three criteria – simple error rate, area under the receiver operating characteristic curve (AUROC), and cumulative lift – and two validation methods, i.e. bootstrap and stratified k‐fold cross‐validation. Systematic experiments are conducted to compare their performance.
Findings
The results suggest that these methods vary in performance across different criteria and validation methods. Overall, neural networks outperform the others in AUROC value and cumulative lifts, and the stratified ten‐fold cross‐validation produces more accurate results than bootstrap validation.
Practical implications
To select predictive models to support direct marketing decisions, researchers need to adopt appropriate performance criteria and validation procedures.
Originality/value
The study addresses the key issues in model selection, i.e. performance criteria and validation methods, and conducts systematic analyses to generate the findings and practical implications.

Abstract
Purpose
The purpose of this paper is to explore the emergence of civil disobedience (CD) movements in Hong Kong in the context of the notion of civil society (CS).
Design/methodology/approach
The paper begins by rigorously defining the notion of CD, as well as the concept of CS and tracing its development in Hong Kong over the past several decades. By using a model of CS typology, which combines the variables of state control and a society’s quest for autonomy (SQA), the paper aims to outline the historical development of CD movements in Hong Kong. It also discusses the recent evolution of CS and its relationship with CD movements, particularly focusing on their development since Leung Chun-ying became the Chief Executive in 2012. Finally, by using five cases of CD witnessed in the past several decades, the relationship between the development of CS and the emergence of CD in Hong Kong has been outlined.
Findings
Four implications can be concluded: first, CD cannot emerge when the state and society are isolated. Second, the level of SC and the scale of CD are positively related. Third, as an historical trend, the development of SQA is generally in linear progress; SQA starts from a low level (e.g. interest-based and welfare-based aims) and moves upwards to campaign for higher goals of civil and political autonomy. If the lower level of SQA is not satisfied, it can lead to larger scale CD in future. Fourth, the CD movement would be largest in scale when the state-society relationship confrontational and when major cleavages can be found within CS itself.
Originality/value
This paper serves to enrich knowledge in the fields of politics and sociology.

Abstract
Purpose
This study incorporates two Chinese cultural variables guanxi (personal relationship) and xinyong (personal trust) with other relational variables that are well defined in the west, i.e. supplier competence, commitment, conflict handling and satisfaction to see how they generate partnership relationship in a sino‐western relationship marketing context.
Design/methodology/approach
Research objectives are achieved through a combination of model building, quantitative design, testing of hypotheses using AMOS and analysis of findings. The subject scope is imbedded within cultural impact on relationship marketing in a sino‐western context.
Findings
This study finds that Western suppliers must be competent in product knowledge, market development, and adaptation to buyers' requirements to resolve conflicts in order to establish their xinyong with the buyers. Competence allows suppliers to show psychological commitment and establish guanxi with the buyers. It also shows that guanxi has a stronger influence on xinyong than on satisfaction. Suppliers should use guanxi to generate buyer's perception on xinyong whilst maintaining a reasonable level of buyer satisfaction with their products and services. Also, relationship between xinyong and satisfaction is not significant. A buyer's satisfaction on the supplier's product and services does not necessarily mean that this buyer perceives the supplier having xinyong because Chinese mix (up) business with personal relationships together and sometimes they make trade‐off between them!
Research limitations/implications
This relationship study was conducted in a single‐product relationship context within the clothing industry in the PRC environment and therefore, its findings may not be generalised to other industry. Future Chinese relationship study should increase the sample size so as to cover more industries to allow comparison across industries. This is especially valid between a manufacturing and a service‐based industry. A service‐based industry may even emphasize more on guanxi and xinyong because of its intangible aspects! Future research should include the xinyong constructs, the concepts of face and reciprocity. To what extent these important Chinese cultural values affect satisfaction and xinyong have not been determined.
Practical implications
Effective conflict handling skills and guanxi are vital to formulate a xinyong positioning strategy. A supplier must be competent in product knowledge, market development skills, and adapt to a buyer's requirements to resolve conflicts with the buyer to establish xinyong.
Originality/value
This research is an initial attempt to establish the relationship between guanxi, xinyong and partnership relationship and generates a new research area in Chinese relationship marketing.

Abstract
Guanxi has been a popular research topic but commentators do not have consensus on its ethical and positioning aspects. Attempts to tackle these two aspects and the problem of guanxi and favor according to a survey in a Sino‐Hong Kong business negotiation environment. Respondents perceived that there are four dimensions within the guanxi concept, i.e. opportunism, dynamism, business interaction, and protectionism. According to these four dimensions, they can be segmented into three clusters, i.e. the preserver, the wiser, and the braver. Different clusters have different psychological approaches to Sino‐foreign negotiation but there is no difference in their perceptions towards the relationship between guanxi and favor. Concludes that guanxi is basically ethical and it can be used as a positioning strategy in China. However, there is some evidence to suggest that guanxi and favor are sensitive and situation‐specific, but further research is needed to confirm these claims.

Abstract
Purpose
This paper seeks to examine the contributions of rehabilitation and redevelopment projects to the labour force of the construction industry in Hong Kong. Major projects from the private and public sectors were critically examined and the manpower requirements and the tangible benefits in terms of wages arising from urban renewal were forecast.
Design/methodology/approach
The forecast of the expected persons to be engaged in the construction industry is based on trend regression model. Time series data of construction sites, both private and public, and persons engaged in the past ten years were forecasted for linear trend process for the next three years. From this, a reasonable estimate of man‐days to be engaged and wages to be incurred in the construction industry in the future can be obtained.
Findings
The results provide evidence that the impacts are positive. About 19.4 million man‐days and an income of HK$16.4 billion (3.8 per cent of the nominal GDP of Hong Kong in 2008) are anticipated in the short run. To meet urban regeneration needs, the Government should develop various vocational skills and enhance motivation and job search.
Research limitations/implications
There are potential risks of error arising from the use of assumptions, limited sample size and data from the secondary resources.
Practical implications
Urban renewal works can generate more jobs. The ratio of development projects to rehabilitation works in terms of producing job opportunity by the same amount of budget is about 1 to 4.7. To meet urban regeneration needs, the Government should develop various vocational skills and enhance motivation and job search for renewal works.
Social implications
Urban renewal attracts and stimulates investment, creates employment opportunities and improves the built environment of cities. Also, public rehabilitation works can play a moderate role in stabilizing the economy and the labour market.
Originality/value
The major contributions of this paper are: the estimated labour and financial resources to undertake such renewal works; and the more significant impact of rehabilitation work identified.

Abstract
Purpose
Cross-border students – children who are permanent residents of Hong Kong but live on the mainland and travel across the border to school every day – have been an important social, educational and political issue in Hong Kong. Nevertheless, current discussions regarding this issue focus mainly on the group of students whose parents are Chinese residents and seldom examine the wider contribution of social, geo-political, global-economic and policy changes to the phenomenon. These shortcomings have limited the understanding of the role of the state and the varied needs of these child migrants from diverse family backgrounds. This paper aims to address these gaps.
Design/methodology/approach
It proposes to bring changing border and immigration policies in Hong Kong back into the current analysis and offers a case study of border history. It revisits publications on Hong Kong’s immigration and migration policies, official statistics and government policy papers and (re)constructs the border changes that took place during the period from 1950 to 2013, which led to the rise and complexity of cross-border students.
Findings
This critical historical review offers two important findings: First, it reveals how the government, through its restrictive and liberalized border regulations, has constrained and produced different types of cross-border families. Second, it shows that cross-border students come from diverse family configurations, which have adopted cross-border schooling as a family strategy.
Originality/value
These findings underscore the importance of historical perspective, the wider context in migration studies, the centrality of the state in migrant families and a differentiated understanding of child migrants.

Abstract
Purpose
The paper aims to explore the extent to which the legal experience of minority shareholder actions in Hong Kong supports the sociological model of the Chinese family firm as developed by Wong Siu‐lun and reports some preliminary findings for the period 1980‐1995.
Design/methodology/approach
This paper is based upon the analysis of 275 minority shareholder petitions in the High Court of Hong Kong between the years 1980 and 1995 inclusive. It also draws upon material from a questionnaire sent to law firms involved in those petitions and interviews with members of the Hong Kong judiciary with experience of hearing minority shareholder cases, members of the legal profession and accounting and company secretarial professions directly or indirectly involved in the administration of companies in Hong Kong and regulators.
Findings
The findings indicate that the problematic early, emergent stage of the model as described by Wong Siu‐lun is quite accurate. Whilst there is considerable support for some aspects of the model of the Chinese family firm, the experience indicates a number of complex dynamics at play, some of which the model does not take into account. However, the findings, at least by implication, do point to the cohesive strength of the Chinese family firm with occasional fault lines resulting in some “disputes” of earthquake proportions which may rumble on in some cases for years.
Practical implications
The findings demonstrate the usefulness of lifecycle modeling of the family and other type of corporate firm. It also demonstrates some of the complex subtleties at play. The findings also have implications for the law matters thesis of La Porta et al.
Originality/value
This is one of the first studies to actually examine the legal experience of minority shareholder protection in a particular jurisdiction (Hong Kong) by examining the petitions and writs actually filed and relating them to a sociological model of the Chinese Family firm.

Abstract
Purpose
Using consumption value theory, this study aims to examine the impact of tourists’ perceived consumption value dimensions of tea beverages offered by Hong Kong (HK)-style cafés, including taste value, price value, health value and emotional value, on tourists’ memorable experience (ME), satisfaction and revisit intention.
Design/methodology/approach
Using an online survey, this study collected 225 usable data from tourists who had experience in visiting HK-style cafés. Partial least squares–structural equation modelling was used to examine the importance of tourists’ value dimensions, including taste value, price value, health value and emotional value, on tourists’ ME, satisfaction and revisit intention.
Findings
The results revealed that taste value, price value, health value and emotional value are significant predictors of tourists’ ME in HK-style cafés, which in turn drive their satisfaction and revisit intention.
Research limitations/implications
This study focusses on a single context: HK-style cafés. Future research may enhance the generalisability of the findings by replicating the model in other countries with diverse cultures.
Practical implications
Tourism marketers may strengthen tourists’ ME, satisfaction and revisit intention by promoting tea beverages as well as HK-style cafés. Tourism marketers are recommended to communicate taste value, price value, health value and emotional value of HK-style tea beverages, which in turn encourages tourists to learn about the features of tea beverages. Subsequently, it drives tourists’ ME and satisfaction, thereby strengthening their intention to revisit.
Originality/value
This study contributes to the tourism marketing literature by providing an understanding of the role of tea beverage value in driving tourists’ ME, satisfaction and revisit intention. By empirically testing a research model, this study confirms that specific consumption value elements of tea beverages, namely, taste value, price value, health value and emotional value, are critical drivers in driving tourists’ ME, satisfaction and revisit intention.

Abstract
Purpose: This paper contains an evaluation of the results from a survey on ISO 9000 certified hotels in Egypt. This study is focused on factors influencing the choice of the registration agency; problems with registration agencies; satisfaction level with the registration agencies and the use of training and consultancy in achieving the certification. Design/methodology/approach: Postal survey was used in this study to gather the required data from a sample size of 40 certified large hotels in Egypt. The sample was drawn from a list provided by ISO 9000 certification office in Egypt. A response rate of 60 per cent was achieved. Findings: The certified hotels in Egypt performed well in their registration process and benefited from ISO implementation. They were using their registration agencies for private consultancy and it has been recommended that they should avoid using their registration agencies for private consultancy as this creates conflict of interest and constitutes a violation of ISO 62. Originality/value: Adds to the body of knowledge concerning the ISO 9000 registration agencies in the service sector with particular focus on Egypt.
