Abstract

Purpose

Smart-home technology (SHT) has been identified by the World Health Organization as a possible solution for assisting older people to maintain their independence and to live safely at home when performing the activities of daily living. This study aims to identify the factors, as well as their inter-relationships, influencing senior citizens to adopt elderly-friendly SHT that supports ageing-in-place in high-density Hong Kong living settings.

Design/methodology/approach

An interpretive structural modelling approach has been used to analyse the factors to develop a better understanding of the relationships between factors influencing SHT adoption, and “Matrice d’Impacts Croisés-Multiplication Appliquée à un Classement” analysis has been used to classify the analysed factors.

Findings

The results suggested that strong government support, efficient backup supporting service and the design of user interface devices have been found as the driving factors encouraging the adoption of SHT. Other factors, including the maintenance of devices, levels of usage and penetration of devices, individual needs and financial considerations, were considered as autonomous factors and are less important to the decision to adopt SHT.

Originality/value

This study provides useful information to policymakers and building designers on the human perspective of SHT adoption, such as the needs and requirements of older people to be considered in SHT technical design and appropriate technological solutions.

Abstract

Purpose

Automated technologies have been applied to facility management (FM) practices to address labour demands of, and time consumed by, inputting and processing manual data. Less attention has been focussed on automation of visual information, such as images, when improving timely maintenance decisions. This study aims to develop image classification algorithms to improve information flow in the inspection-repair process through building information modelling (BIM).

Design/methodology/approach

To improve and automate the inspection-repair process, image classification algorithms were used to connect images with a corresponding image database in a BIM knowledge repository. Quick response (QR) code decoding and Bag of Words were chosen to classify images in the system. Graphical user interfaces (GUIs) were developed to facilitate activity collaboration and communication. A pilot case study in an inspection-repair process was applied to demonstrate the applications of this system.

Findings

The system developed in this study associates the inspection-repair process with a digital three-dimensional (3D) model, GUIs, a BIM knowledge repository and image classification algorithms. By implementing the proposed application in a case study, the authors found that improvement of the inspection-repair process and automated image classification with a BIM knowledge repository (such as the one developed in this study) can enhance FM practices by increasing productivity and reducing time and costs associated with ecision-making.

Originality/value

This study introduces an innovative approach that applies image classification and leverages a BIM knowledge repository to enhance the inspection-repair process in FM practice. The system designed provides automated image-classifying data from a smart phone, eliminates time required to input image data manually and improves communication and collaboration between FM personnel for maintenance in the decision-making process.

Abstract

Purpose

This study aims to understand the impacts of the Minor Works Control System (MWCS) on the performance of minor works contractors following its implementation in 2011, and specifically the initiatives adopted by minor works contractors in response to the new building control regime. Suggestions are made for the further improvement of the MWCS. Like many Western countries and Asian counterparts, Hong Kong has recently implemented a new building control system (the MWCS), which aims to restructure the building proposal approval process and shift the responsibility for building control from the public to the private sector. The effectiveness of the MWCS has been strongly questioned by the industry and the public.

Design/methodology/approach

A mixed method including a questionnaire survey (quantitative) and focus group discussions (qualitative) was adopted to provide an initial evaluation of the impact of the MWCS on practitioners and the industry.

Findings

The results suggest that implementation of the new control system has helped increase safety awareness and the technical capacity of minor works contractors. Despite these benefits, registered contractors are encountering challenges under the MWCS, such as manpower arrangement problems and higher business operating costs. Initiatives that include maintaining a sound financial background, an adequate in-house supervisory staff and a safe working environment are considered critical by practitioners to maintain their competitive edge under the new control regime.

Originality/value

This study is one of the first studies in Hong Kong to evaluate the impact of the new building control system. The feedback and suggestions provided by the practitioners and experts during the research provide valuable insights for the government on how to provide support to practitioners under the MWCS to achieve a better built environment in Hong Kong.

Abstract

Purpose

The construction industry has been criticized for cultural intolerance and its poor industrial image. The ethnically diverse construction workplace in Hong Kong (HK) is frequently noted as a place in which racial harassment and discrimination occurs. The purpose of this paper is to explore the discriminatory experiences and working conditions experienced by ethnic minority (EM) construction operatives in HK.

Design/methodology/approach

A mixed-method approach was adopted, including a questionnaire survey and focus group discussions. The survey identified the thoughts of EM construction workers about racial discrimination and harassment in the workplace. The focus group discussions were aimed at further exploring the discriminatory practices on HK construction sites and possible discrimination-coping strategies.

Findings

Questionnaire data from 100 EM site operatives and labourers mainly from Nepal and Pakistan, but some few from other Asian countries as well as, plus two focus group discussions suggested that indirect and subtle forms of racial harassment do exist on HK construction sites. The operatives sampled reported the existence of inequality of treatment in their working life. Communication difficulties caused by language barriers affect work relationships between different cultural groups on construction sites. EM site operatives tend to interact with workers of similar cultural and ethnic groups. On the corporate/company level, language support and translations of safety procedures notices and policies, should be established to bring staff together and promote a more inclusive and harmonious workplace.

Originality/value

The paper offers insights into the racial discrimination problems in the construction sector in an Asian context, which has been less explored. It aims to provide insight into the EM construction worker's situation in HK as well as the need for developing workplace-specific policies that protect against discrimination and protect the rights of EM workers.

Abstract

Purpose

Since the launch of the Mainland and Hong Kong Closer Economic Partnership Arrangement (CEPA) in 2003, Hong Kong cinema is believed to have confronted drastic changes. Hong Kong cinema is described to be dying, lacking creative space and losing local distinctiveness. A decade later, the rise of Hong Kong – China coproduction cinema under CEPA has been normalized and changed the once pessimism in the industry. The purpose of this paper is to demonstrate how Hong Kong cinema adjusted its production and creation in the first 10 years of CEPA.

Design/methodology/approach

Beginning with a review of the overall development, three paradigmatic cases are examined for reflecting upon what the major industrial and commercial concerns on the Hong Kong – China coproduction model are, and how such a coproduction model is not developed as smooth as what the Hong Kong filmmakers expected.

Findings

Collectively, this paper singles out the difficulties in operation and the limit of transnationality that occur in the Chinese context for the development of Hong Kong cinema under the Hong Kong – China coproduction model.

Originality/value

This is the author’s research in his five-year study of Hong Kong cinema and it contributes a lot to the field of cinema studies with relevant industrial and policy concern.
