Abstract
While many culture researchers have devoted numerous articles to the nature and definitions of culture, relatively fewer articles have contributed towards culture and performance research. The purpose of this study is to investigate the possible relationships between corporate culture and organizational performance among Singaporean companies. The objectives of this study are twofold: first, it aims to investigate the validity of the culture construct. Can culture construct be operationalized along distinct, repeatable dimensions? Second, it attempts to assess how culture affects organizational performance. The organizational culture profile was used as the primary research instrument. Culture was found to impact a variety of organizational processes and performance. While more research remains to be done in this area, this study has demonstrated the power of culture in influencing organizational performance.

Abstract
Purpose
The capacity of landfills will reach saturation in the 2020s. There are more than 50,000 buildings in Hong Kong over 30 years old and which may require extensive refurbishment under the Mandatory Building Scheme. Additionally, most new owners/tenants tend to renovate their premises before moving in. Hence, there is an urgent need in Hong Kong, to explore strategies and measures to enable the development of effective refurbishment and renovation (R&R) waste management for such projects. The objectives of this paper are to investigate the process of R&R for identifying the perceived barriers and thereby the strategies for minimisation and management of R&R waste in Hong Kong.
Design/methodology/approach
Desktop study, semi-structured interviews, site observations and document reviews were used as the data collection methods to achieve the objectives of this research. Considering the nature and characteristics of the industry structure, the snowball sampling process was deployed for data collection. Thematic analysis and content analysis were used for data analysis. Waste minimisation and management strategies for R&R projects were then discussed and developed by the research team and a focus group meeting was held to validate the research findings. Six strategies were then proposed to the government.
Findings
R&R projects contribute 10–20% of the construction and demolition waste. The barriers to recycling of R&R waste can be grouped into six major categories: (1) lack of sorting and storage spaces, (2) high cost, (3) insufficient government supporting policy, (4) complicated recycling processes, (5) immature recycling market and (6) insufficient public education. Also, six strategies are proposed in this study, which include (1) pre-refurbishment audit, (2) development of recycling market, (3) sea reclamation, (4) incineration, (5) government support and (6) education and research.
Originality/value
The strategies and measures proposed in this research could most adequately serve as reference for the government officials, building professionals and academic researchers. Such knowledge would make possible the development of effective strategies and measures for minimising and managing R&R waste.

Abstract
Purpose
This study aims to investigate the behaviour of soft lattices, i.e. lattices capable of reaching large deformations, and the influence of the printing process on it. The authors focused on two cell topologies, the body-centred cubic (BCC) and the Kelvin, characterized by a bending-dominated behaviour relevant to the design of energy-absorbing applications.
Design/methodology/approach
The authors analysed the experimental and numerical behaviour of multiple BCC and Kelvin structures. The authors designed homogenous and graded arrays of different dimensions. The authors compared their technical feasibility with two three-dimensional-printed technologies, such as the fused filament fabrication and the selective laser sintering, choosing thermoplastic polyurethane as the base material.
Findings
The results demonstrate that multiple design aspects determine how the printing process influences the behaviour of soft lattices. Besides, a graded distribution of the material could contribute to fine-tuning this behaviour and mitigating the influence of the printing process.
Practical implications
Despite being less explored than their rigid counterpart, soft lattices are now becoming of great interest, especially when lightweight, wearable and customizable solutions are needed. This study contributes to filling this gap.
Originality/value
Only a few studies analyse design and printing issues of soft lattices due to the intrinsic complexity of printing flexible materials.

Abstract
This study aims to benchmark Chinese TEFL academics’ research productivities, as a way to identify and, subsequently, address research productivity issues. This study investigated 182 Chinese TEFL academics’ research outputs and perceptions about research across three Chinese higher education institutions using a literature‐based survey. ANOVA, t‐tests and descriptive statistics were used to analyse data from and between the three institutions. Findings indicated that more than 70 per cent of the TEFL academics had produced no research in 10 of the 12 research output fields during 2004‐2008. The English Language and Literature Department in the national university outperformed all other departments at the three institutes for most of the research output categories. While a majority of the participants seemed to hold positive perceptions about research, t‐tests and ANOVA indicated that their research perceptions were significantly different across institutes and departments. Developing TEFL research capacity requires tertiary institutions to provide research‐learning opportunities.

Abstract
Purpose
The purpose of this paper is to study the mechanical property of three-dimensional (3D) Printed photopolymer (Vero Yellow and Tango Black) with different constant strain rate. According to the experimental results, three constitutive models are used to describe the stress-strain and stress-time relation in the tension and stress relaxation process.
Design/methodology/approach
The Stratasys Objet 260 was used to prepare the four groups of samples with different photopolymers (Vero Yellow and Tango Black). The stress-strain and stress-time relations are obtained by the uniaxial tensile tests and relaxation tests performed at room temperature with different constant strain rates. The generalized Kelvin model (GKM), standard linearized model (SLM) and fractional order model (FOM) are used to describe experimental data by means of the curve-fitting approach.
Findings
Experimental results show that the tension stress increases faster at a higher strain-rate for tensile tests. Relaxation stress is influenced by the preload strain-rate for relaxation tests. For the theoretical fitting, the error comparison between three constitutive models and experimental data are calculated to demonstrate the high accuracy in describing the stress-strain relationship for tension. For stress relaxation, the error comparison confirms higher accuracy of FOM with the largest error within 3%, while the error of GKM and SLM up to 10%.
Originality/value
The paper confirms the viscous-elastic mechanical property of 3D printed photopolymer composites (Vero Yellow and Tango Black) for Stratasys PolyJet. As FOM shows high accuracy both in describing stress-strain and stress-time relation for tension and stress relaxation process, it can be directly used as a constitutive model to predict mechanical properties for engineering application.

Abstract
Purpose
The purpose of this paper is to determine if the homepage of a web site is representative of the whole site with respect to accessibility.
Design/methodology/approach
The paper presents an intraclass correlation (ICC) between homepage web accessibility barrier (WAB) scores and the WAB scores of web site levels 1 through 3 for 33 popular web sites.
Findings
The paper finds that the homepage is not sufficient to detect the accessibility of the web site. ICC of the homepage and average of levels 1‐3 is 0.250 (p=0.062) and ICC of levels 1, 2, and 3 is 0.784 (p<0.0001). Evaluating the homepage and first‐level pages gives more accurate results of entire site accessibility.
Originality/value
This is first study correlating homepage accessibility with web site accessibility.

Abstract
Purpose
Due to the structural layout, mining process, and working environment, curved chains such as horizontal and vertical bends inevitably exist in the armoured face conveyor (AFC). With the increasing power, conveying capacity, and distance of the AFC, the dynamic influence of these curved chains should be highly emphasized. This paper establishes a dynamic model of the AFC by multi-body system theory and finite segment method, in which the curved chains can be fully considered.
Design/methodology/approach
The scraper chains are firstly grouped into the straight, horizontal bend, vertical convex and concave bend sections. Each bend section running in a circle is simplified as an ideal arc. Through solving its differential equilibrium equation and using Newton's second law, its running resistance is derived. Then the grouped chains are discretized into finite control elements according to the Kelvin model, and the governing equation of each control element is established. The dynamic model of the AFC is obtained by assembling these equations, and the corresponding simulation model is developed by using MATLAB/Simulink.
Findings
Case studies with real scenarios are provided, and simulations are carried out. The results show that the running resistance contributed by the curved chains is larger than the traditional empirical value.
Originality/value
The work in this paper helps the dynamic performance design of AFC, with a deep understanding of the curved chains.

To review conceptual links between research on personal epistemological beliefs and leadership behaviours associated with the transformational‐transactional leadership model.
Abstract
Purpose
To review conceptual links between research on personal epistemological beliefs and leadership behaviours associated with the transformational‐transactional leadership model.
Design/methodology/approach
Transformational leaders act as facilitators of learning in organisations, and therefore their beliefs, cognitions and behaviours can be explored in the same manner as teachers in classroom settings. Research on both personal epistemological beliefs and the transformational‐transactional leadership model is reviewed and key conceptual links are identified in the areas of underlying beliefs, metacognition and cognition, and implications for training.
Findings
The literature review suggests that strong conceptual links exist between mature personal epistemology and beliefs and behaviours associated with transformational leadership. Similarly, conceptual links exist between less mature personal epistemology and beliefs and behaviours associated with transactional leadership.
Research limitations/implications
This is a conceptual paper that will require further empirical investigation. However, studies of the personal epistemology of leaders may provide insights into their behaviours and beliefs associated with transformational and transactional leadership.
Practical implications
Research indicates that personal epistemology can be affected through appropriate interventions. Thus, training programmes designed to facilitate adoption of transformation leadership behaviours could be informed by such research.
Originality/value
This paper is original in its conceptualisations of beliefs potentially underpinning transformational leadership. It offers a new line of inquiry for further research into transformational leadership behaviours and ways that such behaviours can be influenced through metacognitive and cognitive interventions.

Abstract
Purpose
This study aims to explore the global issues of impulse buying, compulsive purchasing and materialism. It examines how materialism relates to self-esteem and the tendencies for impulsive and compulsive buying. In addition, the study delves into the impact of religiosity on self-esteem and materialistic values in an Islamic country.
Design/methodology/approach
Enumerators visited universities, distributing 415 questionnaires and receiving 397 in return. Due to the unavailability of a sample frame for the target population, the study used nonprobability sampling for statistical analysis, which included assessments of normality, reliability, validity and bootstrapping for the structural model, the researchers used Smart PLS.
Findings
The study confirmed 13 hypotheses while rejecting four. The unsupported hypotheses are: (i) materialism negatively impacts impulsive purchasing behavior, (ii) impulsive purchasing does not mediate the relationship between materialism and compulsive purchasing, (iii) materialism does not mediate the relationship between religiosity and impulsive purchasing and (iv) in an Islamic country, neither materialism nor impulsive purchasing significantly mediates the relationship between religiosity and compulsive purchasing.
Research limitations/implications
This study was conducted in a city within a developing Islamic nation, focusing on college students. It suggests that future research could include more cities, a diverse population segments and multicultural perspectives. The research primarily examined the direct relationships between religiosity and factors such as self-esteem, materialism and impulsive purchasing. Future studies could explore religiosity as a mediating factor. This study highlights that materialism (M), impulsive buying (IB) and compulsive buying (CB) are not only closely interconnected but also adversely affect individual, family and societal well-being, raising global concerns. While occasional impulsive behavior is common among individuals in Islamic nations, repeated indulgences in the same behavior could lead to an obsession with excessive purchasing.
Practical implications
This study holds significant implications for consumers and retailers. Excessive and unnecessary spending can increase financial burden and adversely affect family welfare. Often, families and acquaintances inadvertently teach children to engage in extreme purchasing behaviors. To combat this, families and religious leaders should educate individuals about the detrimental effects of impulsive and compulsive purchasing. In addition, colleges and other institutions should organize seminars and workshops to address these issues. Retailers, whose sales largely depend on impulsive and compulsive consumers, should employ interpersonal influencers and brand advocates to connect with this customer segment effectively.
Originality/value
This study examined the relationship between religiosity, materialism, self-esteem and impulsive and compulsive purchasing behaviors. This study thoroughly tested 17 hypotheses, encompassing direct, mediating and multimediating relationships. The findings reveal that materialism’s impact on impulsive behavior is negligible compared to previous research, corroborating the findings presented in the cited literature.
