AbstractCo-phase separation of RNAs and RNA-binding proteins is thought to drive the biogenesis of ribonucleoprotein granules. RNAs can also undergo phase transitions in the absence of proteins. However, the physicochemical driving forces of protein-free, RNA-driven phase transitions remain unclear. Here, we report that RNAs of various types undergo phase transitions with system-specific lower critical solution temperatures (LCSTs). This entropically-driven phase behavior requires Mg2+ions and is an intrinsic feature of the phosphate backbone that is modulated by RNA bases. RNA-only condensates can additionally undergo enthalpically favorable percolation transitions within dense phases. This is enabled by a combination of Mg2+-dependent bridging interactions among phosphate groups and RNA base-stacking / base-pairing. Phase separation coupled to percolation can cause dynamical arrest of RNAs within condensates and can suppress the catalytic activity of an RNase P ribozyme. Our work highlights the need to incorporate RNA-driven phase transitions into models for RNP granule biogenesis.

AbstractAging is associated with loss of circadian immune responses and circadian gene transcription in peripheral macrophages. Microglia, the resident macrophages of the brain, also show diurnal rhythmicity in regulating local immune responses and synaptic remodeling. To investigate the interaction between aging and microglial circadian rhythmicity, we examined mice deficient in the core clock transcription factor, BMAL1. AgingCd11bcre;Bmallox/loxmice demonstrated accelerated cognitive decline in association with suppressed hippocampal long-term potentiation and increases in immature dendritic spines. C1q deposition at synapses and synaptic engulfment were significantly decreased in agingBmal1-deficient microglia, suggesting that BMAL1 plays a role in regulating synaptic pruning in aging. In addition to accelerated age-associated hippocampal deficits,Cd11bcre;Bmallox/loxmice also showed deficits in the sleep-wake cycle with increased wakefulness across light and dark phases. These results highlight an essential role of microglial BMAL1 in maintenance of synapse homeostasis in the aging brain.Significance StatementThis study demonstrates that myeloid deficiency of the circadian clock geneBmal1disrupts microglial synaptic pruning in the hippocampus, accelerates age-associated cognitive decline, and disrupts the sleep-wake cycle.

Published: October 2022

PurposeIslamic crowdfunding, an alternative way to finance social projects, is a new development in Malaysia. Little is known about its operation. This study aims to explore the practice of Nusa Kapital, the first Islamic crowdfunding platform in Malaysia.Design/methodology/approachThis study adopted a descriptive approach. The data was collected through document analysis and interviews with two officials of Nusa Kapital. The data gathered was analyzed through the thematic analysis technique.FindingsThis research discovered that Nusa Kapital was established considering the financing needs of the growing number of small medium enterprises (SMEs) in Malaysia. It uses the murabahah concept to make financing arrangements for entrepreneurs. Murabahah is a debt-based concept where the investors, instead of giving cash to the entrepreneurs, purchase an asset and sell it to them at a cost-plus profit. The Securities Commission Malaysia (SCM) regulates the crowdfunding operation of Nusa Kapital, which sets guidelines for the different types of investors, entrepreneurs and platforms. Nusa Kapital conducts an extensive background check of the company for its creditworthiness and takes the necessary measures for the transparency of the project's operation.Research limitations/implicationsThis study has unique implications for the regulatory authorities and practitioners in Malaysia and global industries. The study explored the practical scenario of the crowdfunding institution, which will be beneficial for similar industries within and outside of the country.Originality/valueWhile previous literature provides a theoretical discussion of Islamic crowdfunding, this study contributes to the body of knowledge by demonstrating its practice.

Authors: Faridi Mohammad Rishad , Mir Aisha Javid Ali 
Published: October 2022

Learning outcomes
Upon completion of the case, students will be able to reflect the forces, which may disrupt the art industry through Artientifique initiatives and the ability to apply Phoenix encounter method with proactive scanning to remain competitive; create various multi-functional roles as a youth entrepreneur in the micro, small and medium enterprises (MSMEs) capacity and be able to understand the level and review the competition and business trends from an art industry perspective; analyze how innovation clubbed with sustainability will create a competitive advantage in a circular economy; determine the leadership style most appropriate for MSMEs to indulge in innovation and sustainability in the fine arts business; and design and discover opportunities to promote women’s entrepreneurship in the art industry, especially in emerging markets.

Case overview/synopsis
On a cold Friday morning in November 2020, Aisha Mir was in utter confusion written all over her face. She had to decide on a prosperous pathway. Should it be customization or standardization of artwork? Also, whether she should continue investing in the existing in-house supply chain or outsource this to a third party. Being practicing sustainability in her personal and professional life, she had designed her art studio herself by using upcycled materials. While enjoying the pigeons and sparrows chirping and eating grains on her wide windowpane, she looked at the world map with keen interest and imagined herself flying to each country along with her gray and white pigeons. While sitting in Madina city, Saudi Arabia, she was concerned about the expired makeup collection hub being set up in Abu Dhabi, UAE. The collection and the painting processes had to be monitored; the artworks needed auditing, framing and packing before they were shipped to a customer. Centralizing would add unnecessary hassle, and outsourcing needed distribution of authority. Keeping the challenges in mind, she was struggling to find a solution for efficient community engagement.

Complexity academic level
This case has been particularly focused on undergraduate and postgraduate early-stage level students pursuing business or commerce programs, particularly those studying entrepreneurial and management courses in innovation and sustainability.

Environmental hazards and health rights of workers in shipbreaking in Bangladesh
Authors: Uddin Md. Kamal , Nobi Mohammad Nur , Islam ANM Moinul 
Published: October 2022

Purpose
The shipbreaking sector in Bangladesh has spurred extensive academic and policy debates on relations between shipbreaking industries, environmental degradation and the health security of their workers. As shipbreaking is an economically significant industry in Bangladesh, it needs to implement both domestic and global mechanisms for environmental conservation and the protection of the labourers’ health from environmental risks. The purpose of this paper is to primarily explore the environmental and health security issues in shipbreaking activities in Bangladesh. It also identifies the challenges in implementing the rules and regulations for protecting the health of the workers at shipbreaking yards in Bangladesh and preserving the marine environment.

Design/methodology/approach
This is a qualitative paper based on secondary materials, including journal articles, books and national and international reports. It critically reviews the existing literature, rules, regulations and policing on shipbreaking with a particular focus on the environment and health security of the workers.

Findings
This paper finds that the implementation of the rules and regulations in shipbreaking in Bangladesh is complicated because of weak implementation mechanisms, political and economic interests of the yard owners, lack of coordination among different agencies, lack of adequate training and awareness among the workers and workers’ poor economic condition, which contribute to the degradation of marine and local environments and trigger health hazards among the workers. Therefore, degrading the environment and undermining occupational health and safety regulations have become regular; thus, accidental death and injury to the workers are common in this sector.

Originality/value
This paper is an important study on the issues of workers' health and safety and environmental hazards in the shipyard. It reports how the health security of the workers in shipbreaking yards in Bangladesh is vulnerable, and environmental rules are challenged. Finally, this paper frames some policy implications to safeguard the workers’ health rights and the marine environment.
Dotaqwaandsyukrpredict Muslims’ proclivity to emotional intelligence? An empirical analysis
Authors: Wahab Mastura Ab. , Masron Tajul Ariffin , Karia Noorliza 
Published: October 2022

PurposeThis paper aims to examine the effects oftaqwa(God-consciousness) andsyukr(gratitude to God) on emotional intelligence (EI) in a Muslim population in Malaysia.Design/methodology/approachStructural equation modelling tool AMOS was used to test the study’s hypotheses. In total, data were sourced from 302 Muslim employees working in Malaysia's public and private sectors.FindingsTaqwa and syukr positively influence EI, and people with taqwa and syukr demonstrate greater levels of self-emotional appraisal compared with other emotional appraisals. This study also shows that people with taqwa and syukr give increased priority to understanding and distinguishing positive and negative emotions because of their understanding of Islamic teachings. They also exhibit concern with knowing their emotions well before advising or responding to the emotions of others. This may increase their sense of empathy, thereby improving their emotional competency and EI.Originality/valueThe findings indicate that taqwa and syukr predispose Muslims to EI. This study applied the Qur’anic model of self-development, which connects the origin of emotion with the soul, thereby further enriching the literature on the subject. It also highlights the importance of taqwa and syukr to Muslim employees for achieving EI that is useful in creating a harmonious atmosphere in the workplace and prosperous relationships in society.

Authors: Ozili Peterson K. , Ademiju Adekemi , Rachid Semia 
Published: October 2022

PurposeThe impact of financial inclusion on economic growth is a topic that is generating widespread interest among researchers and practitioners. In this paper, the authors review the existing literature to highlight the state of research in the literature and identify new opportunities for innovative research.Design/methodology/approachThe authors used a thematic literature review methodology which involves dividing the review along relevant themes.FindingsThe authors find that significant research on the topic emerged in the post-2016 years. Most of the existing studies are from developing countries and from the Asian and African regions. Existing studies have not utilized relevant theories in explaining the impact of financial inclusion on economic growth. Most studies report a positive impact of financial inclusion on economic growth while very few studies show a negative impact. The most common channel through which financial inclusion affects economic growth is through greater access to financial products and services offered by financial institutions that increases financial intermediation and translates to positive economic growth. The common empirical methodology used in the literature are causality tests, cointegration and regression methods. Multiple proxies of financial inclusion and economic growth were used in the literature which partly explains the conflicting result among existing studies. The review paper concludes by identifying some directions for future research.Originality/valueThis paper presents the first rigorous thematic review of the existing literature on the impact of financial inclusion on economic growth. It highlights the main approach that researchers have taken on this topic and identifies some important research areas for future investigation.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/IJSE-05-2022-0339.

Authors: Shuyi Jiang , Mamun Abdullah Al , Naznen Farzana 
Published: October 2022

PurposeThe world has been forced to implement movement restriction strategy because of the COVID-19 pandemic, and industries have to embrace online technologies and social media marketing activities (SMMAs) to continue their business operations. Considering the aftermath of COVID-19 on the business world, this study aims to explore the determining elements of SMMAs and analyse how these factors affect brand equity (BE), relationship equity (RE) and purchase intention (PI) among smartphone consumers in China. Five constructs of SMMAs, namely, entertainment (EN), interactivity (IN), trendiness (TR), customisation (CU) and electronic word-of-mouth (WM), were examined to examine the effects of SMMAs on BE and RE. Subsequently, the mediation effects of BE and RE on the relationships of all constructs of SMMAs with PI were analysed.Design/methodology/approachAn online survey was conducted with the participation of 347 Chinese consumers who used social media platform managed by the smartphone brands as their marketing activities during COVID-19. The data were analysed via structural equation modelling using SmartPLS.FindingsThis study’s result showed the significant and positive influence of CU, TR and WM on BE and the strong and positive influence of CU, IN and TR on RE. Furthermore, BE was found to fully mediate the relationships of CU, TR and WM with PI, while RE was found to mediate the relationships of TR and CU with PI. The performance and impact factor analysis revealed RE as the most important factor for PI, followed by BE, CU and TR.Originality/valueThis study extended the authors’ knowledge and understanding about social media marketing, BE and smart phone PI during COVID-19. Findings of this study can assist smartphone brands in China to develop the most effective strategies for SMMAs, which can be tailored for consumers to maximise profits, even during any crisis when physical business activities are deemed difficult. Moreover, this study’s findings can benefit the government and policymakers in developing and regulating rules and regulations for e-commerce and social media commerce for all industries and areas.
Helical tool path generation based on the triangle mesh model for a rotary four-DOF 3D printer
Authors: Zhao Donghua , He Jiapeng , Zhu Gaohan , Han Youcheng , Guo Weizhong 
Published: October 2022

Purpose
The rapid development of three-dimensional (3D) printing makes it familiar in daily life, especially the fused deposition modeling 3D printers. The process planning of traditional flat layer printing includes slicing and path planning to obtain the boundaries and the filling paths for each layer along the vertical direction. There is a clear division line through the whole fabricated part, inherited in the flat-layer-based printed parts. This problem is brought about by the seam of the boundary in each layer. Hence, the purpose of this paper is to propose a novel helical filling path generation with the ideal surface-plane intersection for a rotary 3D printer.

Design/methodology/approach
The detailed algorithm and implementation steps are given with several worked examples to enable readers to understand it better. The adjacent points obtained from the planar slicing are combined to generate each layer's helical points. The contours of all layers are traversed to obtain the helical surface layer and helical path. Meanwhile, the novel rotary four-degree of freedom 3D printer is briefly introduced.

Findings
As a proof of concept, this paper presents several examples based on the rotary 3D printer designed in the authors’ previous research and the algorithms illustrated in this paper. The preliminary experiments successfully verify the feasibility and versatility of the proposed slicing method based on a rotary 3D printer.

Originality/value
This paper provides a novel and feasible slicing method for multi-axis rotary 3D printers, making manufacturing thin-wall and complex parts possible. To further broaden the proposed slicing method’s application in further research, adaptive tool path generation for flat and curved layer printing could be applied with a combination of flat and curved layers in the same layer, different layers or even different parts of structures.
Sexual selection moderates heat stress response in males and females
Authors: Moiron Maria , Winkler Lennart , Martin Oliver Yves , Janicke Tim 
Published: October 2022

Abstract

A widespread effect of climate change is the displacement of organisms from their thermal optima. The associated thermal stress imposed by climate change has been argued to have a particularly strong impact on male reproduction but evidence for this postulated sex‐specific stress response is equivocal.

One important factor that may explain intra‐ and interspecific variation in stress responses is sexual selection, which is predicted to magnify negative effects of stress. Nevertheless, empirical studies exploring the interplay of sexual selection and heat stress are still scarce.

We tested experimentally for an interaction between sexual selection and thermal stress in the red flour beetle Tribolium castaneum by contrasting heat responses in male and female reproductive success between enforced monogamy and polygamy.

We found that polygamy magnifies detrimental effects of heat stress in males but relaxes the observed negative effects in females. Our results suggest that sexual selection can reverse sex differences in thermal sensitivity, and may therefore alter sex‐specific selection on alleles associated with heat tolerance.

Assuming that sexual selection and natural selection are aligned to favour the same genetic variants under environmental stress, our findings support the idea that sexual selection on males may promote the adaptation to current global warming.

Abstract

Keystone species are disproportionately important for ecosystem functioning. While all species engage in multiple interaction types with other species, keystone species importance is often defined based on a single dimension of their Eltonian niche, that is, one type of interaction (e.g. keystone predator). It remains unclear whether the importance of keystone species is unidimensional or if it extends across interaction types.

We conducted a meta‐analysis of tripartite interaction networks examining whether species importance in one dimension of their niche is mirrored in other niche dimensions, and whether this is associated with interaction outcome, intimacy or species richness.

We show that keystone species importance is positively associated across multiple ecological niche dimensions, independently of abundance, and find no evidence that multidimensionality of keystone species is influenced by the explanatory variables.

We propose that the role of keystone species extends across multiple ecological niche dimensions, with important implications for ecosystem resilience and conservation.

‘Don’t think that we die from AIDS’: Invisibilised uncertainty and global transgender health
Authors: Farber Reya 
Published: October 2022

AbstractThe invisibilisation of social groups in health research and survey data is a source of medical uncertainty, long seen as a hallmark of the medical field. However, scholarship has not thoroughly assessed how medical uncertainty is structured by state‐level processes and global health agendas, especially for people beyond the Global North. This article introduces invisibilised uncertainty as a type of medical uncertainty structured by global organisational and state‐level priorities, which can invisibilise social groups and health problems from research and data collection, exacerbating medical uncertainty and health disparities for people worldwide. Based on 14 months of fieldwork in Thailand and in‐depth interviews with 62 participants, the article illuminates how state‐level processes and global clinical research agendas have structured knowledge gaps and uncertainties for Thai transgender women. As omissions in health research and data collection become embodied on a world scale, the article expands our understandings of how gendered health disparities are structured nationally and globally. It advances a sociology of medical ignorance by analysing the uneven landscape of holistic transgender health research, parsing how institutional dynamics can prioritise or invisibilise people and health issues in research and data, and structure uncertainties.
Promotion or liberalization: The effect of targeted investment policies on foreign direct investment inflows
Authors: Inada Mitsuo 
Published: October 2022

AbstractInvestment policies have been implemented by policy‐makers in both developed and developing countries to open up their domestic markets to the foreign affiliates of multinational enterprises (MNEs). This study empirically examines two foreign direct investment (FDI) policies: targeted promotion and selective liberalization. It quantifies which of the two targeted measures is more effective in attracting FDI inflows and stimulating the activities of MNEs. We implement a difference‐in‐differences estimation that measures the effects of FDI policies by comparing affected and non‐affected industries before and after the change of the FDI policies in compliance with China's accession to the World Trade Organization. Using aggregated data on foreign equity and output by MNEs' foreign affiliates in China from 1999 to 2007, the results show that selective liberalization has a positive impact on FDI inflows, especially from incumbents; however, targeted promotion does not. Our results highlight the effectiveness of selective liberalization as a policy option for stimulating industrial growth.
