Knowledge creation and application of optimal tolerance distribution method for aircraft product assembly
Authors: Miah Md Helal , Zhang Jianhua , Singh Chand Dharmahinder 
Published: November 2021

Purpose
This paper aims to illustrate the tolerance optimization method based on the assembly accuracy constrain, precession constrain and the cost of production of the assembly product.

Design/methodology/approach
A tolerance optimization method is an excellent way to perform product assembly performance. The tolerance optimization method is adapted to the process analysis of the hatch and skin of an aircraft. In this paper, the tolerance optimization techniques are applied to the tolerance allocation for step difference analysis (example: step difference between aircraft cabin door and fuselage outer skin). First, a mathematical model is described to understand the relationship between manufacturing cost and tolerance cost. Second, the penalty function method is applied to form a new equation for tolerance optimization. Finally, MATLAB software is used to calculate 170 loops iteration to understand the efficiency of the new equation for tolerance optimization.

Findings
The tolerance optimization method is based on the assembly accuracy constrain, machinery constrain and the cost of production of the assembly product. The main finding of this paper is the lowest assembly and lowest production costs that met the product tolerance specification.

Research limitations/implications
This paper illustrated an efficient method of tolerance allocation for products assembly. After 170 loops iterations, it founds that the results very close to the original required tolerance. But it can easily say that the different number of loops iterations may have a different result. But optimization result must be approximate to the original tolerance requirements.

Practical implications
It is evident from Table 4 that the tolerance of the closed loop is 1.3999 after the tolerance distribution is completed, which is less than and very close to the original tolerance of 1.40; the machining precision constraint of the outer skin of the cabin door and the fuselage is satisfied, and the assembly precision constraint of the closed loop is satisfied.

Originality/value
The research may support further research studies to minimize cost tolerance allocation using tolerance cost optimization techniques, which must meet the given constrain accuracy for assembly products.
Linking sustainability reporting frameworks and sustainable development goals
Authors: Stefanescu Cristina Alexandrina 
Published: November 2021

PurposeThis study aims to explore the linkages between sustainable development and sustainability reporting by approaching the UN’s 2030 Agenda in connection with the Integrated Reporting (IR) and Global Reporting Initiative (GRI) frameworks. It aims to outline a theoretical model able to support the achievement of sustainable development goals (SDGs) through appropriate reporting.Design/methodology/approachThe research methodology follows a qualitative approach, combining content and benchmarking analyses of the official documents in question. It aims to provide a better understanding of the conceptual matches between the “5 Ps” of sustainable development and the two sustainability reporting frameworks (IR and GRI) by breaking them down into components and overlapping their constituents to highlight the connections.FindingsThe results reveal that both sustainability reporting frameworks provide prerequisites to ensure SDGs achievement due to the embedded sustainability issues. As there are more matches between SDGs and the capitals implied in the pursuit of value creation, IR better fits to become part of the sustainable development strategy as a valuable option for reporting on SDGs.Practical implicationsThe study addresses academia through a better understanding of the connections between SDGs and sustainability reporting. It might help regulators to improve their latest efforts to enhance transparency and comparability through the enactment of Directive 2014/95, as long as it has not imposed a standardised report yet. It could guide practitioners to face future challenges and support their steps towards standardised reporting practices.Originality/valueThis paper approaches the newsworthy topic of sustainable development, outlining a conceptual model meant to support the SDGs achievement through appropriate standardised reporting. It might also fill the gap of the Directive 2014/95 on non-financial information disclosure as it identifies the most suitable type of reporting to enhance the harmonisation at the European level.

Authors: Konstantoulaki Kleopatra , Rizomyliotis Ioannis , Cao Yifei , Christodoulou Ioannis 
Published: November 2021

PurposeThis study aims to explore the effect of social media engagement on the determinants of behavioural intention. Specifically, the authors empirically research the three behavioural intention determinants, namely, attitude, subjective norms and perceived behavioural control (PBC), and confirm their effect on students' intention to enrol on a university online programme.Design/methodology/approachA conclusive research analysis is followed, and a moderation analysis is conducted to test the hypotheses of the model. Empirical evidence from 201 students in the UK higher education is used and a structural equation modelling approach is followed.FindingsThe findings suggest a significant effect of social media engagement on attitude, subjective norms and PBC. The latter three are confirmed as determinants of the intention to enrol on a university online programme. Mindfulness is found to positively moderate the effect of the three determinants on behavioural intention.Originality/valueThis study advances knowledge pertaining to the theory of planned behaviour (TPB) by highlighting the effect of social media engagement on the determinants of the intention to enrol on a university online programme. Additionally, the moderating role of mindfulness is also tested with regards to its effect on the relationship between behavioural intentions and its determinants.
Too much of a good thing: the non-linear effect of vertical pay dispersion on vice presidents’ voluntary turnover rate
Authors: Xiong Xiaoguo , Chen Weihong , Zhong Xi 
Published: November 2021

Purpose
While the effect of vertical pay dispersion on the voluntary turnover rate of vice presidents (VPs) has received attention, the existing research conclusions are still divided. Therefore, this study aims to explore the relationship between vertical pay dispersion and voluntary turnover rate of VPs in a Chinese context using data from listed firms.

Design/methodology/approach
Integrating tournament theory and social comparison theory, this study examines the non-linear effect of vertical pay dispersion on VPs’ voluntary turnover rates using empirical data from Chinese A-share listed firms from 2007 to 2016.

Findings
The results reveal a U-shaped relationship between vertical pay dispersion and the voluntary turnover rate of VPs. After further incorporating the moderating effect of the board governance structure, the effect is found to be enhanced in firms with more efficient board governance (i.e. smaller board size, higher board turnover and higher proportion of outside directors). Further analysis indicates that the aforementioned conclusions mainly exist in non-state-owned enterprises rather than state-owned enterprises.

Originality/value
The findings deepen the understanding of the costs and benefits associated with vertical pay dispersion, enrich the research findings on pay dispersion and contribute to the integration of previously inconsistent findings.
Systematic review on the identification of safety risks in off-site manufacturing (OSM)
Authors: Vithanage Sadith Chinthaka , Sing Michael , Davis Peter , Pillay Manikam 
Published: November 2021

Purpose
Off-site manufacturing (OSM) has emerged as a method of modern construction that provides several benefits including achieving lower costs, a quicker schedule and environmentally friendly solutions. Although numerous researches are available that advocate the adoption of OSM, the devotion towards OSM safety is somewhat limited. However, OSM invariably generates safety risks, including dynamics and uncertainty in safety management. There is a unique call to have an investigation on the identification of OSM safety risks.

Design/methodology/approach
To provide a full picture on the OSM safety, a systematic literature review was adopted based on interpretivist philosophical stance. The literature search was conducted in key electronic databases to identify OSM safety-focused publications. Bibliometric analysis was adopted to identify co-occurrences of keywords and collaboration among authors in OSM safety-related research publications. Content analysis was conducted to provide a taxonomy of OSM safety risks. The identified studies were critically analysed to determine the focus of OSM safety research and provide future research directions.

Findings
The results demonstrated frequently appeared OSM safety aspects while highlighting the limitedness of collaborative research outputs in common authorships. Content analysis subsequently unveiled safety risks in OSM under human, organisational and work environmental factors. A critical analysis of extant literature revealed seven research classifications of OSM safety. Directions were offered to enhance OSM safety by applying principles of targeted safety management concepts, technology-driven safety measures and bespoke training programs.

Originality/value
This study provides a comprehensive review on the identification of safety risks throughout OSM while presenting the avenues useful for the development of OSM safety management strategies.
Why ethnic minority groups’ online-startups are booming in China’s tight cultural ecosystem?
Authors: Li Lifu , Kang Kyeong 
Published: November 2021

Purpose
Although most Chinese ethnic minority groups (EMGs) hold conservative thinking to online-startups, the new entrepreneurial model is booming on live streaming platforms. In China’s tight cultural ecosystem, the tight cultural control would lead EMG entrepreneurs to keep conservative thinking and avoid challenging careers. Still, it would be helpful for Chinese Governments to issue systematical entrepreneurial policies and improve online-startup environment for EMGs. To discover the relationships among influencing factors and EMGs’ online-startup motivation, this paper aims to draw on the tight and loose cultural theory and the capability-opportunity-motivation-behaviour (COM-B) behaviour changing theory and establishes the research model based on China’s tight cultural ecosystem.

Design/methodology/approach
Through analysing 617 questionnaires from 37 EMGs based on the partial least squares path modelling and variance-based structural equation modelling method, the study proves that environmental opportunity factors and personal capability factors have positive impacts on EMGs’ online-startup motivation and EMGs’ conservative thinking negatively moderates the relationship between their online-startup motivation and entrepreneurial development behaviour. In addition to testing the hypotheses, the paper also measures the importance-performance map analysis to explore additional findings of influencing factors and provide suitable suggestions for EMG entrepreneurs and related departments.

Findings
Regarding the environmental opportunity unit, both policy support and platform support significantly impact Chinese EMGs’ motivation to promote online-startups. For the personal capability unit, a platform using skills positively influences Chinese EMGs to develop online-startups. Meanwhile, EMG cultural knowledge is also necessary for EMG entrepreneurs because abundant cultural resources can be applied to live content and attract online consumers’ watching interests. Furthermore, influenced by the tight cultural control, Chinese EMGs tend to hold conservative thinking to new careers and it negatively moderates the relationship between Chinese EMGs’ online-startup motivation and their final entrepreneurial behaviours. Finally, Chinese EMGs’ online-startup motivation positively affects them to develop online-startups on live streaming platforms.

Originality/value
This study uses the tight and loose cultural theory to analyse the Chinese entrepreneurial environment and discover influencing factors based on the tight cultural ecosystem. Meanwhile, based on the COM-B behaviour changing theory, this paper divides influencing factors into three different units, including the environmental opportunity unit, the personal capability unit and the Tight cultural control unit. Considering the inter-relationships among these units, the research model is established based on the tight cultural ecosystem to discover Chinese EMGs’ online-startup motivation.

Indoor environment and student productivity for individual and collaborative work in learning commons: a case study
Authors: Hong Sungil , Kim Yujin , Yang Eunhwa 
Published: November 2021

PurposeThis study investigates the relationships between the built environments of learning commons and user productivity, such as collaborative and individual work productivity and overall environmental satisfaction.Design/methodology/approachA case study was conducted in a learning commons building at a higher education campus in the USA. The data collection and analysis were conducted with the survey responses of satisfaction with indoor environments and perceived productivity as well as the objective indoor environmental quality (IEQ) measurements. Statistical analysis was performed, including descriptive analysis, principal component analysis (PCA), regression analysis and ANOVA test.FindingsThe study presents that satisfaction with noise level is positively associated with individual productivity. The results imply that the spatial properties of open-plan commons, such as visibility and accessibility, are associated with space users' interactions and collaborative productivity. Overall satisfaction is in a positive relationship with lighting satisfaction, study supporting artifacts and furniture configuration. The results of this study reveal the importance of meeting the standards in IEQ factors on individual productivity and the spatial features preferred by space users that facilitate tasks and activities.Originality/valueThe mixed-method approach, including subjective and objective data collection of IEQ, is rarely utilized to show the relationships with perceived productivity. This study investigates a unique building design feature such as step seats in relation to space use and perceived productivity. The findings inform library leadership about environmental characteristics related to the user experience in learning commons, a new format of academic libraries.

Authors: Jaffri Zain Ul Abidin , Ahmad Zeeshan , Kabir Asif , Bukhari Syed Sabahat Hussain 
Published: November 2021

Purpose
Antenna miniaturization, multiband operation and wider operational bandwidth are vital to achieve optimal design for modern wireless communication devices. Using fractal geometries is recognized as one of the most promising solutions to attain these characteristics. The purpose of this paper is to present a unique structure of patch antenna using hybrid fractal technique to enhance the performance characteristics for various wireless applications and to achieve better miniaturization.

Design/methodology/approach
In this paper, the authors propose a novel hybrid fractal antenna by combining Koch and Minkowski (K-M) fractal geometries. A microstrip patch antenna (MPA) operating at 1.8 GHz is incorporated with a novel K-M hybrid fractal geometry. The proposed fractal antenna is designed and simulated in CST Microwave studio and compared with existing Koch fractal geometry. The prototype for the third iteration of the K-M fractal antenna is then fabricated on FR-4 substrate and tested through vector network analyzer for operating band/voltage standing wave ratio.

Findings
The third iteration of the proposed K-M fractal geometry results in achieving a 20% size reduction as compared to an ordinary MPA for the same resonant frequency with impedance bandwidth of 16.25 MHz and a directional gain of 6.48 dB, respectively. The operating frequency of MPA also lowers down to 1.44 GHz.

Originality/value
Further testing for the radiation patterns in an anechoic chamber shows good agreement to those of simulated results.

Nature-based activities for people living with dementia: a nice day out or a matter of human rights?
Authors: Evans Simon Chester , Atkinson Teresa , Rogerson Mike , Bray Jennifer 
Published: November 2021

Purpose
There is growing interest in and evidence for the benefits of connecting with nature for people living with dementia, sometimes known as “green care”, including reduced stress, improved sleeping and even enhanced cognition. However, many people living with dementia are denied such opportunities, often because of practitioner perceptions of risk and poor design of outdoor spaces. This paper reports on the evaluation of a project that worked with national providers to give people living with dementia opportunities and support to access the natural environment.

Design/methodology/approach
The evaluation adopted a mixed-methods approach, using a combination of bespoke and commonly used tools and in-depth case study work to identify the facilitators and challenges to delivering the project and explore the experiences of activity participants.

Findings
Qualitative measures indicated a significant improvement in mental well-being for participants with dementia and family carers following attendance at activity sessions. Research interviews indicated that participants enjoyed activities based on connecting with nature. Being outdoors was a major factor in the experience, along with taking part in activities that were meaningful and opportunities for social interaction.

Originality/value
This paper provides evidence for the benefits of connecting with nature for people living with dementia. This paper concludes that access to the outdoors is not a luxury, it is a basic human right and one which has become increasingly important in light of restrictions that have emerged as a result of the COVID19 pandemic.
Community co‐produced mental health initiatives in rural Australia: A scoping review
Authors: De Cotta Tracy , Knox Jasmine , Farmer Jane , White Carolynne , Davis Hilary 
Published: November 2021

AbstractIntroductionInaccessibility of mental health services in rural Australia is widely reported. Community co‐produced mental health and well‐being initiatives could fill gaps and complement other services.ObjectiveThis scoping review summarises findings from peer‐reviewed articles to identify the key features of co‐produced Australian rural mental health initiatives that engage communities in their design, delivery or evaluation processes.DesignBetween 2009 and 2019 inclusive, 14 articles met inclusion criteria and were reviewed using Arksey and O'Malley's review methodology.FindingsCommunities co‐produced initiatives through informing, collaborating and instigating them. Some initiatives operated in specific places, for example an art gallery, while others operated across regions. Only two initiatives involved community members in multiple activities targeting prevention, early intervention, education and service accessibility; other initiatives were more focused, for example designing a new service. Over half of initiatives found were targeted at Aboriginal and Torres Strait Islander Peoples. Most articles discussed evaluation approaches, though methods were diverse.DiscussionPublished peer‐reviewed evidence about Australian rural community co‐produced mental health initiatives appears scant. Evidence found suggests they generate a range of supports that could complement or mitigate for lack of, public health services. The overall lack of evidence, diversity of initiatives and inconsistent evaluation makes it difficult to assess effectiveness and which activities might be scaled‐up for wider benefit.ConclusionRural communities have limited resources, and evidence of what constitutes best practice in co‐producing mental health services would help to avoid ‘reinventing the wheel.’ Greater efforts in evaluating and publishing about initiatives would be helpful.
