Multi-coil design for a coaxial double-cylinder head MRI scanner
Authors: Xuan Liang , Xu Zheng 
Published: May 2022

Purpose
Gradient coils designed by conventional target field methods usually have a complex physical structure and these methods are not convergent for complex routing area problems. This study aims to design a multi-coil (MC) gradient system arranged on a complex routing area including two cylindrical surfaces with different radii for a head magnetic resonance imaging scanner.

Design/methodology/approach
A MC system model is established. In this model, the sub-coils are evenly distributed on two cylindrical wiring surfaces, and the radii of coils are the same on one cylindrical surface. With the target magnetic field set, the currents in every individual coil are solved by constrained least-squares fitting based on the Levenberg–Marquardt method.

Findings
The magnetic field nonlinearity generated by designed coils is validated as 4.50% and 3.57% for X-gradient coil and Z-gradient coil, respectively, which satisfy the mainstream nonlinearity standards. The analysis of the optimization results indicates that hardware requirements can be considerably reduced by connecting coils with the same currents in series.

Originality/value
High-linearity gradient magnetic fields are generated on complex routing areas by adopting the MC structure. In addition, the requirements for current sources and amplifiers are considerably reduced.
Intelligent series inducing switching scheme (ISISS) to enhance power delivery in shaded photovoltaic array
Authors: Vadivel Srinivasan , C.S. Boopathi , R. Sridhar , Kaovasia Tarana 
Published: May 2022

Purpose
The aim of this research study is to mitigate shading impact on solar photovoltaic array. Photovoltaic (PV) array when getting shaded not only results in appreciable power loss but also exhibits multiple power peaks. Due to these multiple power peaks, the maximum power point tracking (MPPT) controllers’ performance will be affected, as most of the times it ends up in tracking the local maximum power peak and not the global power peak.

Design/methodology/approach
The PV panels in an PV array when getting shaded even partially would result in huge power loss. The pattern of shading also plays a crucial role, as it renders a cascaded impact on the overall power output because the cells/panels are connected in series and are parallel. Therefore, during shading, intelligent schemes are needed to appropriately connect and discard the unhealthy and healthy panels in right place with right combination. This research proposes one such scheme to mitigate the shading impact.

Findings
To mitigate the shading impact and also to have a smooth power-voltage (P-V) curve, a new series inducing switching scheme is introduced. The proposed scheme not only mitigates the shading impact and enhances the output power but also smoothens the P-V curve that facilitates the MPPTs to track the P-V appropriately.

Originality/value
The research findings are inventive in nature and not copied work. The reference works and the inspirations have been duly cited and credited.
Teleworking during the COVID-19 pandemic: a leader-member exchange perspective
Authors: Chang Yuhsuan , Chien ChungJen , Shen Li-Fang 
Published: May 2022

PurposeThe COVID-19 pandemic has accelerated the process of teleworking and teleworking is expected to be a central feature of workplaces of the future. The present study examines the effect of leader-member exchange (LMX) and perception of loneliness on the relationship between proactive coping and the work productivity of teleworkers during the COVID-19 crisis time.Design/methodology/approachUsing structural equation modeling (SEM), this study the study is based on a survey of 572 teleworkers in Taiwan drawn from a variety of industry sectors.FindingsThrough the application of a hypothesized moderated mediation model, the indirect effects of proactive coping on work productivity via LMX are stronger for employees who experience a higher level of perceived loneliness.Research limitations/implicationsThe results have contributed to current understanding on the success of telework at the individual level and extends research framework of teleworking. Using self-report questionnaire is one of the limitations; however, this was feasible data collection method during COVID-19.Practical implicationsOrganizations need to provide further training aimed at enhancing proactive coping and dealing with future work challenges in the complex and dynamic workplace.Originality/valueThis study is the first among its type to examine proactive coping and job productivity from a LMX during COVID-19.
Predicting crowdfunding success with visuals and speech in video ads and text ads
Authors: Al-Qershi Osamah M. , Kwon Junbum , Zhao Shuning , Li Zhaokun 
Published: May 2022

PurposeFor the case of many content features, This paper aims to investigate which content features in video and text ads more contribute to accurately predicting the success of crowdfunding by comparing prediction models.Design/methodology/approachWith 1,368 features extracted from 15,195 Kickstarter campaigns in the USA, the authors compare base models such as logistic regression (LR) with tree-based homogeneous ensembles such as eXtreme gradient boosting (XGBoost) and heterogeneous ensembles such as XGBoost + LR.FindingsXGBoost shows higher prediction accuracy than LR (82% vs 69%), in contrast to the findings of a previous relevant study. Regarding important content features, humans (e.g. founders) are more important than visual objects (e.g. products). In both spoken and written language, words related to experience (e.g. eat) or perception (e.g. hear) are more important than cognitive (e.g. causation) words. In addition, a focus on the future is more important than a present or past time orientation. Speech aids (see and compare) to complement visual content are also effective and positive tone matters in speech.Research limitations/implicationsThis research makes theoretical contributions by finding more important visuals (human) and language features (experience, perception and future time). Also, in a multimodal context, complementary cues (e.g. speech aids) across different modalities help. Furthermore, the noncontent parts of speech such as positive “tone” or pace of speech are important.Practical implicationsFounders are encouraged to assess and revise the content of their video or text ads as well as their basic campaign features (e.g. goal, duration and reward) before they launch their campaigns. Next, overly complex ensembles may suffer from overfitting problems. In practice, model validation using unseen data is recommended.Originality/valueRather than reducing the number of content feature dimensions (Kaminski and Hopp, 2020), by enabling advanced prediction models to accommodate many contents features, prediction accuracy rises substantially.
An overview of the state of urban resilience in Iran
Authors: Moradpour Nabi , Pourahmad Ahmad , Hataminejad Hossein , Ziari Keramatollah , Sharifi Ayyoob 
Published: May 2022

Purpose
In Iran, the frequent occurrence of disasters has always been a major problem. In recent decades, disasters have created considerable challenges, especially in cities. Hence, understanding the levels of urban resilience (UR) and planning for addressing vulnerabilities plays a key role in the era of increasing risks and uncertainties. The present study aims to provide a comprehensive overview of the state of resilience of Iranian cities.

Design/methodology/approach
A systematic literature review method was used to determine how resilient Iranian cities are. To find relevant studies, the authors searched Iranian and international databases such as Scopus, ScienceDirect, SID and Magiran. There was no restriction on the inclusion date, meaning that all papers published up until September 16, 2021 were considered for inclusion. The PRISMA framework was used for literature search and selection and, finally, 153 studies focused on 52 cities of Iran were selected for the systematic review.

Findings
In general, the results showed that the level of resilience was low in Iranian cities. Also, informal settlements, worn-out urban fabrics and the central parts of cities showed lower resilience than other parts.

Originality/value
The results of the study can be used to inform municipal authorities, urban planners and non-governmental organizations of the actions that need to be taken to enhance the resilience of Iranian cities.
How diverse are Shariah supervisory boards of Islamic banks? A global empirical survey
Authors: Kachkar Omar , Yilmaz Mustafa K. 
Published: May 2022

Purpose
This study aims to examine diversity in the composition of Shariah supervisory boards (SSBs) of Islamic banks (IBs). It investigates diversity from two perspectives: existing composition of SSBs and the regulatory frameworks and standards of selected Organisation of Islamic Cooperation countries. Diversity characteristics include education, nationality, gender and age.

Design/methodology/approach
A list of all full-fledged Islamic commercial banks (FFICBs) globally has been carefully prepared and confirmed. Conventional banks with Islamic windows, non-commercial banks, takaful companies and other Islamic financial institutions are excluded. The available profiles of 428 SSB members have been scrutinised and analysed. These board members occupy 522 SSB positions in 238 FFICBs operating in 52 countries around the globe. From the regulatory perspective, 12 national and international Shariah governance frameworks and standards have been examined.

Findings
Findings of this paper indicate various levels of diversity in SSBs of the reviewed IBs. The level of diversity in educational background and in the nationality of SSBs can be described as generally acceptable. However, a lack of diversity in gender and age among SSB members is evidently observed in IBs. While the lack of age diversity in SSBs may be relatively justified as a common trend in the composition of corporate boards, SSBs of IBs are seriously lagging behind in gender diversity. On the regulatory level, this study concluded that provisions on diversity as a requirement in SSBs are almost non-existent in the existing regulatory frameworks and standards.

Research limitations/implications
The major limitation of this study is the lack of available information on the SSB members.

Practical implications
This paper provides insights for IBs and policymakers concerned with the corporate governance of IBs and all Islamic financial institutions. First, it offers an excellent bird’s-eye view of the status of diversity in SSBs of IBs. Second, it motivates policymakers and standard-setting bodies to ensure, through the relevant regulatory frameworks, adequate levels of diversity in the composition of SSBs. Diversity in SSBs of IBs and Islamic financial institutions should be given special emphasis, not only in boards and top management positions but also in the workplace. This is of profound significance to the reputation of Islamic finance industry which has been recently under mounting pressure to translate the rhetoric about the Islamic finance industry being ethical, fair, just, equitable and inclusive into genuine implementations.

Originality/value
To the best of the authors’ knowledge, this study is the first of its kind to examine the diversity of SSB members from the regulatory as well as from the implementation perspective.
From connective actions in social movements to offline collective actions: an individual level perspective
Authors: Bernroider Edward W.N. , Harindranath G. , Kamel Sherif 
Published: May 2022

PurposeThe purpose of this study is to investigate the role of connective action characterised by interconnection and personal communication on social media (SM) for participating in collective action in the physical world of social movements.Design/methodology/approachA research model is developed integrating different modes of connective action into the social identity model of collective action (SIMCA) to investigate pathways to participating in offline collective action (CA) from an individual perspective. Following a survey design approach, data collected from 194 respondents in the background of Egypt's social movements are examined using partial least squares (PLS) path modelling and mediation analyses.FindingsThe authors' main results reveal that interactive socialisation (IS) on SM provides an important momentum for the user to internalise (consume) and externalise (share) content online from a social learning perspective. In terms of translating these activities to participating in offline CA, the authors find support for two independent causal chains: An “instrumental” chain building on content externalisation (CE) and efficacy considerations and an “obligatory” chain based on content internalisation (CI) and collective identity.Originality/valueThe authors' results highlight the individual-level origins of offline mobilisation in social movements, which are not only grounded in social-psychology, but also develop out of interrelated connective actions supporting social learning. Prior work has mainly conceptualised the value of SM in social movements for online political communication. The authors' conceptualisation is novel in terms of integrating online and offline behaviours with social-psychological perspectives and the application with primary data in a protest movement context that heavily relied on connective actions for offline mobilisation.

Authors: Wickramasinghe Vathsala 
Published: May 2022

Purpose
The purpose of this paper is to investigate the determinants of pay satisfaction of executive-level employees in public sector of Sri Lanka, which follows an open pay system.

Design/methodology/approach
The perceptions of equity, love of money, justice and seven individual and socio-demographic characteristics were investigated as the determinants of pay satisfaction. The survey methodology is used for data collection.

Findings
The findings showed equity, love of money, justice, the years of work experience in public sector, the number of income earners in the family and the number of dependents in the family as the significant predictors of pay satisfaction. Gender is identified as a significant predictor of love of money.

Originality/value
This study investigated the dynamics of pay satisfaction in a novel research context – i.e. public sector, an open pay system, gender equality in the pay system and an Asian developing country.
Integrative work design for telework practices: lessons learned from the COVID-19 pandemic in Thailand
Authors: Popaitoon Patchara 
Published: May 2022

Purpose
This study aims to identify an effective work design for telework practices in Thailand by investigating the influence on employee work engagement and job stress of job demands and resources in three domains of work characteristics – task, social and contextual.

Design/methodology/approach
In total, 1,052 high-intensity teleworkers participated in our online survey. Nested model comparisons and chi-square difference tests were used to test the significance of the three domains of work characteristics by comparing changes in model fit associated with the removal of the parameters associated with each domain. The best fit model was then used to examine the hypothesized relationships.

Findings
The results revealed that each domain of work characteristics provides additional and meaningful insights on employee outcomes. For telework practices in Thailand, supervisor support and work autonomy, the job resources specified respectively in the social and task domain can enhance work engagement. In contrast, supervisor surveillance and communication overload, the job demands in these respective domains can lead to job stress. Additionally, telework contextual demands of blurred work–life boundaries reduce employee work engagement. Communication overload has paradoxical outcomes of increased job stress and improved work engagement.

Originality/value
This study contributes to the work design and telework literature by applying an integrative work–design approach to demonstrate that organizations should consider both job demands and resources in a wider context of work design. This study also provides insights in respect of Thai cultural values to explain the effective design of telework practices in Thailand, a country where telework is relatively new and the work–design literature is very limited. This study is useful for international business managers wishing to adopt telework practices in Thailand to localize how telework is organized and ensure a smooth transition to the new world of work more successfully in the post-pandemic period.
Multi-homing in B2B services: a psychological perspective
Authors: Manchanda Mohit , Deb Madhurima 
Published: May 2022

Purpose
Extant literature on business-to-business (B2B) has largely ignored studying multi-homing through a psychological lens. This paper aims to outline the results of three constituent studies, which were designed to reveal potential differences in multi-homers’ versus single-homers’ loyalty behaviors in a B2B and supply chain management (SCM) setting; identify factors that differentiate single-homers and multi-homers in these settings; and examine the relevance and effect of perceived risk on multi-homing behaviors.

Design/methodology/approach
In Studies 1 and 2, the authors used a questionnaire-based survey to capture the perceptions of 503 and 458 SCM experts, respectively. They then deployed AMOS v.21 to perform structural equation modeling. In Study 3, the authors used a mixed-methods approach to interview 18 SCM experts and then applied these insights to a survey with 242 SCM experts.

Findings
Study 1 reveals that multi-homers’ loyalty toward their preferred SP has a weaker effect on willingness to pay premium prices and share-of-wallet than single-homers’ loyalty. Study 2 establishes that several attitudinal factors distinguish multi-homers from single-homers in a loyalty framework. Study 3 concludes that perceived risk dimensions promote multi-homing intention, which in turn promotes multi-homing behavior.

Originality/value
Through empirical investigation, the present research succeeds in establishing that multi-homing is a concern for SPs, deciphering the attitudinal factors that distinguish multi-homers and single-homers in a loyalty framework, and confirming the influence of perceived risk dimensions on multi-homing. Thus, the study has several theoretical and practical implications for B2B services in emerging economies.
“Lay down your heart” [bwaga moyo]: heritage as a driver for urban regeneration in the East-African stone town of Bagamoyo
Authors: Vande Keere Nikolaas , Plevoets Bie , Winkels Peggy , Mosha Livin 
Published: May 2022

PurposeThe paper aims to elaborate on the potential for regeneration of Bagamoyo (Tanzania) through adaptive reuse of its heritage sites. The town was the most important harbour for ivory and slaves of the East-African mainland during the 19th and early 20th century and the colonial capital of German East-Africa between 1885 and 1890. Today, it has 85,000 inhabitants who mainly live in informal settlements while stone town closer to the coast is largely abandoned with its historical buildings in a poor state of conservation.Design/methodology/approachThe first part of the paper describes the history and heritage of the old stone town Bagamoyo, and how it impacts its identity. Additionally, it summarises the critical reception of the town's role in the application to UNESCO World Heritage for “The Central Slave and Ivory Trade Route”. This, in order to consider the reuse of its heritage sites more as part of a layered regeneration process than of a singular narrative for preservation. The second part presents research-by-design proposals investigating the economic, social and cultural potentialities of three spatial layers: the main street, the coastal strip and the shoreline.FindingsThe identity and therefore also urban regeneration of post-colonial towns such as Bagamoyo is the result of a complex combination of different narratives rather than of a singular one.Originality/valueBagamoyo's heritage has been studied as a driver for international tourism linked to slavery but without successful implementation. This study proposes an alternative perspective by investigating its potential for urban regeneration in line with local needs. Developed in the context of a master studio of architectural design, it presents an innovative didactic approach. Moreover, the methodology of research-by-design can be inspirational for other historical towns.
Moral identity and engagement in sustainable consumption
Authors: Salciuviene Laura , Banytė Jūratė , Vilkas Mantas , Dovalienė Aistė , Gravelines Žaneta 
Published: May 2022

Purpose
This study aims to identify the effects of moral identity on consumer engagement in sustainable consumption, and discover any moderating gender effects. The authors deploy regret and identity theories to propose hypotheses and explain research findings.

Design/methodology/approach
Data collection was via online survey, and analysed using partial least squares structural equation modelling to test hypotheses.

Findings
Symbolization and internalization dimensions of moral identity are positively associated with five dimensions of engagement. Moreover, the relationship between moral identity and specific dimensions of engagement in sustainable consumption is stronger among males than females.

Originality/value
This study suggests a novel mechanism in a hitherto under-researched area in the sustainability and moral identity literature, viz. consumer engagement in sustainable consumption when moral identity is present. This research also adds to current knowledge regarding gender effects in the link between the symbolization and internalization dimensions of moral identity and engagement in sustainable consumption.
COVID and the club: conversations with Boys & Girls Club leaders on providing services during the COVID-19 pandemic
Authors: Prochnow Tyler , Patterson Megan S. , Umstattd Meyer M. Renee 
Published: May 2022

Purpose
Boys & Girls Clubs of America (BGCs) provide numerous avenues for youth to connect, be physically active and have healthy meals/snacks. These services are often provided to low-income families at reduced cost to bridge the gap in after school and summer childcare. However, many of these clubs were forced to dramatically change their services during the COVID-19 pandemic. This study aims to examine how 13 BGCs in Texas, USA, experienced COVID-19 and persevered to provide services.

Design/methodology/approach
Interviews were conducted with 16 BGC leaders from 13 different BGCs. Open-ended questions were used to elicit leaders’ experiences with the pandemic, services their clubs were able to offer, barriers overcome and supports crucial to their ability to serve their communities. Thematic analysis was used to generate findings from these interviews.

Findings
BGC services changed significantly during the pandemic. Normal activities were no longer possible; however, leaders (alongside their communities) continually provided services for their families. Further, leaders reiterated the power of the community coming together in support of their families.

Social implications
While BGC leaders had to adapt services, they found ways to reach families and serve their community. These adaptations can have dramatic impacts on the social and physical well-being of children in their communities. Learning from this adversity can improve services as clubs start to build back.

Originality/value
This study provides vital context to the changing care and setting children were exposed to during the pandemic response. Additionally, these results provide understanding of the adaptations that took place in these services.
