The purpose of this paper is to examine the potential impacts of various variables on product return activities after online shopping. Previous studies on customer behaviour have been predominantly concerned with return on used products and other product-quality-related constructs in the model. This study aims to specially examine the logistics service-related and customer intention–related variables for general products under the e-commerce circumstance.

Structured questionnaire data for this study were collected in the two southeast cities of China (162 useable responses). Structural equation modelling was used to examine the latent variables.

The results confirmed that product return intention has the greatest impact on online shopping returns with a direct effect of 0.63, followed by the flexibility in return (logistics service) with a direct effect of 0.49.

Such a model not only enriches the theoretical understanding of customer behaviour studies but also offers online shopping stores and platforms a quantitative benchmark and new perspective on the design of online shopping supply chains by considering product returns so as to improve the customer satisfaction.

This paper identifies and discusses that parks, as one kind of open space, must be open not only for some people, but for everyone, including those with special needs such as visually impaired people. The paper further identifies a number of key directions for the policy, design and management of park environments and facilities that will promote openness and social inclusion.

The study was qualitative in nature. Case study approach on park environments and facilities was adopted. Used site studies, field observations, interviews with the government officials and professionals of planners, designers and management were conducted. Direct interviews with the visually impaired people were conducted during the field observation. Some of them were also invited to participate in participatory research workshops to give comments and suggestions on the design and management of park environments and facilities.

Open spaces are important and necessary for all. However, visually impaired people are always indirectly excluded from open spaces such as parks, which are important for the quality of urban life. Three areas that require attention to improve the accessibility of parks: ways of identifying and approaching the parks; overall environmental setting of the parks; and facilities inside the parks. Assistance to visually impaired people can be further categorized into information provided in advance and information provided on-site.

Further case studies are expected to be conducted in other kinds of open space and other cities in order to generate a more comprehensive understanding related to the topic. Continuous studies are also necessary since the park environments and facilities are changing all the time. With the users ' participation, in particular those with special needs, in research is important.

The findings provide reference and direction for the governments, designers and managment to plan, design and manage parks for the needs of visually impaired people. The findings also advocate inclusive and universal approach in planning, implementation and management of parks.

The findings identify that visually impaired people most of the time are indirectly excluded from accessing parks as well as other open spaces.

Although the paper was based on a case study in Hong Kong, its practical and social implications are also important to other places. Although barrier-free concept and requirement have been enforced in many places for some years, people with special needs (in particular visually impaired people) still face a lot of “barriers” in their daily life. The findings provide insights for researchers and also policymakers, designers and management to review the needs of the visually impaired.

This paper aims to propose a set of flexible design principles for enhancing the flexibility of street furniture to deal with the diverse and changing urban environment. Flexibility is an important but less considered element of public design (otherwise called public environment and facility design), especially in regard to the street furniture that is encountered in everyday life. Taking Hong Kong as a case study, this paper gives an overview of the concepts of flexibility and flexible design, and identifies the current limitations and problems of the current street furniture design practices with respect to the diverse and changing urban environment.

Based on a review of the current literature and relevant documentation, interviews with government officers and different groups of users (including those with special needs), and field observations in Hong Kong’s urban areas over a period of four years, the policies relating to street furniture design in Hong Kong and its management and implementation were evaluated.

The results indicate that the current street furniture in Hong Kong is unable to adapt to or resist changes, can easily cause safety and management problems and is not adaptable to new developments. This paper proposes six principles for the flexible design of street furniture, namely, custom in use, multifunctional use, responds effectively to changing circumstances, easily and conveniently managed, universal in use and sustainable in use.

It is difficult to understand the diverse needs and preferences of different users in urban environments. The findings in this paper are based on intensive field work and broad industry experience. To deal with the rapid and ongoing urban change, this paper recommends a further long-term and in-depth study of street furniture.

Based on the findings, this paper proposes six flexible design principles for designing street furniture that is sufficiently flexible to meet the rapid and ongoing urban change and diverse users’ needs.

Different societies and urban areas faced different types and levels of changes. Therefore, a flexible approach to street furniture design is important and necessary.

The findings of this paper and the proposed six flexible design principles can provide insight and direction for government officials, design and planning professionals, developers, utility and management companies and communities on how to embed public design (i.e. policy, implementation and management) in the future.

This paper aims to address convenience as a prominent feature of a scheduled society and examines the nature of convenience, identifies the waste collection system and recycling programmes in some densely populated areas in Asia and discusses the existing barriers to enhancing the convenience of the recycling facilities in Hong Kong. The paper further identifies some recommendations for the policy and design of recycling practices and facilities.

In this qualitative study, two districts in Hong Kong from 2013 to 2014 were used as case studies. The research methods included field observations, semi-structured interviews and ethnographic research. The locations for field observation included lobbies, corridors, lifts, ground floors and streets. Direct interviews were conducted with residents, cleaners, government officials and expert planners and environmentalists. In-depth interviews and observations were conducted with six families following the interviews to identify important issues that might have been ignored in the semi-structured interviews and field observations.

A holistic understanding of convenience in a scheduled society is effective in the design of high-quality recycling facilities. In terms of convenience, the gap between recycling and not recycling is rather obvious in Hong Kong. Therefore, it is necessary and important to adjust the difference in the degree of convenience regarding refuse disposal and recyclable collection. In addition, the enhancement of economic incentives could shift the degree of convenience and encourage public participation in recycling. The challenges of specific living conditions and social contexts should also be taken into account to enhance the convenience of recycling.

Further case studies are expected in other countries and cities with the purpose of gaining an in-depth understanding of the means by which to approach the convenience of recycling programmes within various social contexts. Comprehensive and continuous studies on these factors are recommended throughout the design and implementation processes to account for constantly changing situations. A clear understanding of convenience from the perspective of the users is important.

The findings provide reference and direction for a holistic approach to the design and management of recycling facilities in Hong Kong. The findings also advocate the consideration of convenience from the perspective of the users.

The findings illustrate how to design and manage public facilities for waste recycling in ways that encourage household and community participation in terms of convenience.

The paper identifies the manner by which the culture of convenience and an institutionalised rhythm influence recycling practices. Although substantial studies on recycling indicate that convenience is a necessary characteristic of designs and services, the nature of convenience and the means by which to approach convenience in terms of public facilities are seldom discussed. The paper proposes several recommendations on the basis of the studies of the refuse collection programmes in other areas of Asia and case studies in Hong Kong. The findings provide insights for policymakers, researchers and designers to improve the design of public facilities.

The purpose of this study is to determine how to achieve a balance between freedom and control in public space. It analyses the relationship between freedom and control to identify phenomena and offer users and policymakers instructions for achieving that balance. Public space, including privately owned public space, is important to urban living. People have both the right to use public space and the responsibility to protect it. Both freedom and control should exist in public space in an appropriate combination. It is impossible and inappropriate for us to ask for absolute freedom or endure unreasonable control.

A case study of Hong Kong’s Mass Transit Railway (MTR) reveals typical freedom/control relationships. Quantitative descriptions are given based on field observations.

Freedom and control are primary factors affecting the quality of urban life and management of city space. They depend on and conflict with each other. The balance between freedom and control is a balance between diverse spaces. The “freedom space” belonging to both citizens and authorities determines whether freedom and control are balanced. Ethics and strategies constitute control. Only when each authority and user obtains a proper freedom space can freedom and control achieve balance in public space.

Freedom and control differ across cities because they are both affected by culture, history and tradition. As each city has its own characteristics, the freedom and control in each open space are distinctive. Balancing freedom and control requires an understanding of a city’s background and the era. While this paper does not attempt to achieve this understanding, further studies could devote more attention to dimensions of time and location.

The findings provide recommendations for users, policymakers and construction and management companies that will allow the management of harmonious and high-quality open spaces.

Freedom and control are two main factors affecting quality of life. The balance between freedom and control may bring a harmony and stable society environment. It would benefit both the authority and the people a lot.

This study provides a systematic analysis of freedom and control in public space and makes a valuable contribution to quality urban space policy, design and management.

The purpose of this paper is to discuss how the participatory approach should be considered and applied in research for the disabled. It aims to arouse the awareness of policymakers, professionals, researchers and the general public that disabled people must not only be considered, but also invited to participate in research actively in order to bring real benefit to disabled people.

An in‐depth case study related to policy, implementation and management quality of tactile guide paths (TGP) was carried out in Hong Kong. Participatory approach was adopted to explore how to help visually impaired people (VIP) access places independently. The methods included group discussions, direct individual interviews, field studies and intensive observations.

The quality of TGP is still unsatisfactory in policy, implementation and management aspects in that VIP still face a lot of difficulties in accessing places, in particular the places they have never gone before. Two of the major causes of poor quality of TGP are misunderstanding and neglect. VIP, as well as other disabled people, still face many difficulties arising from different sources; from the grant society policies to small objects in their daily lives.

VIP should not be considered as a group of people with ills, trouble and problems in the society. Policymakers, professionals in design and implementation and management people must recognise that they should not impose their value judgments and preferences on VIP. Instead, user participation is a good and applicable approach to assure a high quality of design.

The paper offers insights into quality assurance for user‐fit designs.

Conventional shopping-scapes are designed to promote a linear form of consumption. Products are moved from production systems through consumer distribution nodal points. The consumption of commodities through these points is promoted as the main, if not only, legitimate activity of shopping centres. A circular economic (CE) paradigm offers an alternative to the current model of linear consumption so that there are restorative processes to ensure products, components and materials are valued at all stages of product life (Ellen Macarthur Foundation, 2013). However, this model, like its contemporary linear model, overlooks the opportunities for more socially rewarding consumption that could particularly be addressed through the shopping scape. The ByeBuy! Shop was conceived to test ideas on an alternative shopping scape to increase social engagement and reduced consumption without the use of money for exchange. Accordingly, it is used here to exemplify a CE paradigm.

This study aims to address policy, implementation and management, the three stages of inclusive open space. It compares both the level of design and implementation of open space in Beijing, Hong Kong and Taipei by following the inclusive guidelines. It also identifies recommendations for policy, implementation and management of inclusive open space and its facilities.

Field observations were conducted in 27 parks within three cities. In-depth interviews were conducted with a variety of participants, including visually impaired persons, government officers, representatives of non-governmental organisations, local communities and experts.

Most of the so-called inclusive environments and facilities have not been user-friendly in actual practice. The findings suggest that policies are an essential precondition; however, implementation and management must not be ignored because they ensure the effectiveness of inclusive design.

Comprehensive and continuous studies on the proposed framework are recommended throughout the policy, implementation and management processes.

The findings serve as a reference and direction for taking a holistic approach to inclusive design of open space in densely populated cities.

This study examines the levels of inclusive open space and illustrates how to provide barrier-free environments that can be used by the widest spectrum of people.

This study evaluates policy, implementation and management in the three cities based on 29 guidelines generated from seven principles of inclusive design. A research framework is proposed for researchers and policymakers to consider how to achieve effective inclusive open spaces.

The development of a given discipline in science and technology often depends on the availability of theories capable of describing the processes which control the field and of modelling the interactions between these processes. The absence of an accepted theory of information retrieval has been blamed for the relative disorder and the lack of technical advances in the area. The main mathematical approaches to information retrieval are examined in this study, including both algebraic and probabilistic models, and the difficulties which impede the formalization of information retrieval processes are described. A number of developments are covered where new theoretical understandings have directly led to the improvement of retrieval techniques and operations.

A survey of current work on database systems is presented. The area is divided into three main sectors: data models, data languages and support for database operations. Data models are presented as the link between the database and the real world. Languages range from formal algebraic languages to attempts to use a dialogue in English to formulate queries. The support includes hardware for content addressing, database machines and software techniques for optimizing and evaluating group expressions. Mathematical models are used to organize this support. Throughout there is a tutorial component and evaluation, which in both cases is related to the application of database ideas to documentation.
