Activity-dependent Mitochondrial ROS Signaling Regulates Recruitment of Glutamate Receptors to Synapses
Authors: Doser Rachel L. , Knight Kaz M. , Deihl Ennis , Hoerndli Frederic J. 
Published: August 2023

SUMMARYOur understanding of mitochondrial signaling in the nervous system has been limited by the technical challenge of analyzing mitochondrial functionin vivo. In the transparent genetic modelCaenorhabditis elegans,we were able to manipulate and measure mitochondrial signaling as well as neuronal activityin vivo. Using this approach, we provide evidence supporting a novel role for mitochondrial signaling in dendrites. Specifically, we show that dendritic mitochondria take up calcium (Ca2+) via the mitochondrial Ca2+uniporter MCU-1 causing an upregulation of mitochondrial reactive oxygen species (mitoROS) production. We also observed that mitochondria are positioned in close proximity to synaptic clusters of GLR-1, theC. elegansortholog of the AMPA subtype of glutamate receptors that mediate neuronal excitation. We show that synaptic recruitment of GLR-1 is downregulated by mitoROS signaling resulting from mitochondrial Ca2+uptake via MCU-1. Thus, postsynaptic mitochondria provide a means of negative feedback that regulates excitatory synapse function which may be vital for neuronal homeostasis by preventing excitotoxicity and energy depletion.

AbstractSporadically genetic material that originates from an organelle genome integrates into the nuclear genome. However it is unclear what processes maintain such an integration over longer evolutionary time. Recently it was shown that nuclear DNA of mitochondrial origin (NUMTs) may harbour genes with intact mitochondrial reading frames despite the fact that they are highly divergent to the host’s mitochondrial genome. Two major hypotheses have been put forward to explain the existence of such mitocoding nuclear genes: (A) recent introgression from another species and (B) long-term selection. To address whether these intriguing possibilities do play a role we scanned the genomes of more than 1,000 avian and mammalian species for NUMTs. We indeed identified that the subclass of divergent NUMTs harbouring mitogenes with intact reading frames are widespread across mammals and birds. We can show that for these NUMTs signatures of cross-species introgression are widespread in birds, but not mammals with the exception of ungulates. We can also show that a substantial fraction of deeply divergent NUMTs are maintained by selection. For a small number of NUMT genes we identify an evolutionary signature that is consistent with adaptive evolution including one human NUMT that is shared among seven ape species. This highlights the intriguing possibility that NUMT insertions occasionally may be functional.
Integrating technology acceptance model with diffusion of innovation theory: an empirical investigation of the usage behaviour of XBRL-based Malaysia business reporting system
Authors: Uyob Roslee , Ku Bahador Ku Maisurah , Saad Ram Al Jaffri 
Published: August 2023

Purpose
This study aims to investigate the usage behaviour associated with adopting the extensible business reporting language-based Malaysia business reporting system (MBRS). An extended technology acceptance model (TAM) was used, which was tested and examined using both the TAM and the diffusion of innovation theory (DIT).

Design/methodology/approach
The empirical results were obtained from 267 members of the Malaysian Institute of Accountants, who are responsible for preparing and filing company reports with the Companies Commission of Malaysia.

Findings
The findings show that user intention has a significant impact on MBRS usage behaviour. Perceived usefulness, perceived ease of use and cost have an impact on users’ intention to use, while attitude and compatibility have no impact. Only perceived ease of use has a significant impact on user attitude. For perceived usefulness, cost and compatibility are found to have a significant impact but not perceived ease of use.

Originality/value
To the best of the authors’ knowledge, this is the first study that integrates TAM and DIT to analyse MBRS usage behaviour.

Published: August 2023

Purpose
The growing trend in environmental, social and governance (ESG) research, along with its relevance to the financial performance of firms, has gained a lot of attraction in academia and industry. This study aims to fill the existing gap in the literature by conducting a thorough systematic review with the latest research articles in this area.

Design/methodology/approach
This study adopted a blend of systematic literature review and bibliometric techniques. A proper search string was used to retrieve the data from the Scopus database. The final dataset comprises 296 documents used for science mapping, and the review was done of 60 articles finalised after further refining the documents.

Findings
The results of this study indicate that stakeholder, legitimacy and signalling theories are the foundation for ESG and financial performance. Social firms have a lower capital cost because of their low-risk potential. Moreover, this study provides the knowledge structure by framing four clusters, “CSR/ESG determinants and firm performance”, “Moderators and Mediators”, “Investors’ perception” and “CSR in the tourism sector”.

Originality/value
This study has reviewed the literature with both tools, that is, qualitative (systematic review) and quantitative (bibliometric). Moreover, this study presents the latest synthesis of the literature.
The impact of cryptocurrencies on the gold, WTI, VIX index, G7 and BRICS index before and during COVID-19: a quantile regression and NARDL analysis
Authors: Aloui Mouna , Hamdi Besma , Tiwari Aviral Kumar , Jeribi Ahmed 
Published: August 2023

Purpose
This study aims to explore the impact of cryptocurrencies (Bitcoin, Ethereum, Monero and Ripple) on the gold, WTI, VIX index, G7 and the BRICS index before and during COVID-19.

Design/methodology/approach
This research analyzes the impact of cryptocurrencies (Bitcoin, Ethereum, Monero and Ripple) on the gold, WTI, VIX index, G7 and the BRICS index before and during COVID-19, using the quantile regression approach for the 2016–2020 period. In addition, to catch long- and short-run asymmetries of cryptocurrencies on aforementioned dependent variables, an asymmetric nonlinear co-integration (nonlinear autoregressive distributed lag [NARDL]) approach is applied.

Findings
The result of the quantile regression shows that in a high market, which corresponds to the 90th quantile, the FTSE MIB, CAC40, SSE, BSE 30, and BVSP stock market showed a statistically insignificant negative coefficient, on the Bitcoin price. In a middle and low markets, which correspond to the 0.2, 0.3 and 0.5th quantiles, the BVSP, FTSE MIB, S&P/TSX, SSE and Nikkei stock markets show statistically significant and positive on Bitcoin. Evidence from the NARDL shows a statistically significant positive impact of cryptocurrencies on the gold, WTI, VIX index, G7 and BRICS indices before and during COVID-19 pandemic.

Originality/value
These results can provide investors with valuable analysis and information and help them make the best decisions and adopt the best strategies. Therefore, future investigations may concentrate and examine the monetary and governmental policies to be adapted to face the COVID-19 pandemic’s dangerous effects on both the society and the economy. For this reason, investors should take this into account when making their asset allocation decisions. Moreover, the portfolio managers, such as index funds, may consider few eligible cryptocurrencies for their inclusion into the portfolio. However, the speculators present in both stock and crypto markets may opt for a spread strategy to improve their portfolio returns.

Authors: Amin Hanudin , Hassan M. Kabir , Shaikh Imran Mehboob 
Published: August 2023

Purpose
The purpose of this study is to examine donors’ or waqifs’ desire for waqf-based qardhul hassan financing in Malaysia using a maqasid method, where a pragmatic approach is used.

Design/methodology/approach
Using judgemental sampling, a total of 275 waqifs participated in this work to identify their preference in donating their money to the facility should it is introduced. Using the developed waqf-based qardhul hassan scale (WAQASCALE), this study examined the preference accordingly. Data were analysed using IBM SPSS 27.

Findings
The results obtained were as follows: the first factor considered by the waqifs in donating money was perceived household well-being, followed by perceived recipients’ welfare, perceived mankind benevolence and perceived Muslims’ community security.

Research limitations/implications
The authors developed construct items that had generalisability issues as they were at the infancy stage of development among social finance scientists along with the narrow geographical constraint where the actual survey was conducted.

Practical implications
The results were useful in giving new guidance to state governments and Islamic banks (IBs) in Malaysia to explore further this sort of facility for the improved well-being of those affected by COVID-19. Besides, sustainable development goals (SDGs), such as poverty, hunger and responsible consumption, among others can be addressed effectively for the mutual well-being of those affected by the health crisis in an effort of combating financial hardships in the meeting of basic needs, at least. The partnership between the state government and IBs could lead to the offered qardhul hassan financing-sourced funding from waqf for reduced financial hardships by needy and poor folks.

Originality/value
This study introduced a new WAQASCALE in the context of qardhul hassan financing in Malaysia.

Information technology and people involvement in organizational performance through supply chain collaboration
Authors: Rashid Aamir , Rasheed Rizwana , Amirah Noor Aina 
Published: August 2023

Purpose
Supply chain collaboration (SCC) benefits organizational performance (OP). Although it is complex, it is also hard to implement and measure collaborative initiatives in the field of the supply chain. This study aims to examine the role of information technology (IT) and people’s involvement in OP through the mediation of supply chain collaboration.

Design/methodology/approach
This study used a deductive and quantitative approach to test the research hypotheses. Data was collected from 249 supply chain professionals working at various manufacturing firms.

Findings
This research found a significant effect of IT on supply chain collaboration. Similarly, people involvement (PI) also significantly influenced the supply chain collaboration. For the mediation hypotheses, SCC significantly mediates the relationships between two independent variables (IT and PI) and OP. Furthermore, the full mediation of SCC occurred.

Originality/value
This study provides a framework emphasizing manufacturing firms’ practices, SCC and OP. The “people involvement” was found as a novel variable in the tested model using the resource-based view as a supporting theory. The research findings can benefit the professionals working on supply chain business processes to improve OP.
Garment sizing system development for Amhara policemen uniforms using data mining techniques
Authors: Bizuneh Berihun , Destaw Abrham , Hailu Fasika , Tsegaye Solomon , Mamo Bizuayehu 
Published: August 2023

Purpose
Sizing system is a fundamental topic in garment fitting. The purpose of this study was to assess the fit of existing police uniforms (shirt, jacket, overcoat and trousers) and develop a sizing system for upper and lower body uniforms of Amhara policemen in Ethiopia.

Design/methodology/approach
In total, 35 body dimensions of 889 policemen were taken through a manual anthropometric survey following the procedures in ISO 8559:1989 after each subject was interviewed on issues related to garment fit. The anthropometric data were pre-processed, key body dimensions were identified by principal components analysis and body types were clustered by the agglomerative hierarchical clustering algorithm and verified by the XGBoost classifier in a Python programming environment. The developed size charts were validated statistically using aggregate loss and accommodation rate.

Findings
About 44% of the subjects encountered fit problems every time they own new readymade uniforms. Lengths and side seams of shirts, and lengths and waist girths of trousers are the most frequently altered garment sites. Analysis of the anthropometric measurements resulted in 13 and 15 sizes for the upper and lower bodies, respectively. Moreover, the comparison of the developed upper garment size chart with the existing size chart for a shirt showed a considerable difference. This indicates that inappropriate size charts create fit problems.

Originality/value
The study considers the analysis of fit problems and sizing system development in a less researched country. Moreover, the proposed data mining procedure and its application for size chart development is unique and workable.
Sociology of corporate governance and the emerging disintermediation
Authors: Bolton Joel , Yoder Michele E. , Gong Ke 
Published: August 2023

Purpose
This study aims to observe and discuss an emerging disintermediation in transportation, finance and health care, and explain how these three key areas depend on intermediary institutions that are the fruit of modern corporate governance conditions that find their roots in classical sociological theory.

Design/methodology/approach
The authors review and incorporate a diversity of research literature to explain the likelihood for the development and continuation of disintermediation.

Findings
The authors map two sociological perspectives (Emile Durkheim’s theory of interdependence and Herbert Spencer’s theory of contracts) to two modern corporate governance theories (resource dependence theory and agency theory). The authors then discuss the challenging social situation resulting from modern corporate governance and show how these conditions create the potential for a continuum of disintermediation across the specific and crucial economic sectors of transportation, finance and health care.

Originality/value
The implications of this theoretical integration can help organizational leaders navigate complex social and strategic issues and prepare for the consequences that may result from the emerging disintermediation.
Can we do it alone? The case of De Cyber hotel
Authors: Ahmad Halimah Nasibah , Amran Noor Afza , Arshad Darwina 
Published: August 2023

Research methodology
The interviews were conducted with the respondents (the founder and Manager of De Cyber Hotel). Other data were obtained through the websites of the relevant businesses.

Case overview/synopsis
Siti Alia and her friends established De Cyber Hotel in January 2019. It was incorporated as a Malaysian private limited company in Cyberjaya, Selangor. Siti Alia was appointed as the hotel manager and was responsible for managing the hotel’s day-to-day operations and financial matters. Being a new budget hotel, competing with other established hotels was quite difficult. De Cyber Hotel used brochures and word-of-mouth for its promotion activities and mainly depended on walk-in guests. Siti Alia knew she had to take immediate action to ensure the hotel’s survival and could no longer rely on walk-in guests. Hence, to increase the occupancy and revenue rate, on 27 March 2019, De Cyber Hotel management decided to accept an offer from ABC Digital Booking to implement a digital booking mechanism and form a partnership for at least a year. ABC Digital Booking provided an online system to enable the listing and booking of budget accommodations and partnered with hotels to provide similar guest experiences across countries. After working and collaborating for 10 months with ABC Digital Booking, Siti Alia had to decide whether De Cyber Hotel should continue its alliance with ABC Digital Booking. Hence, she had to think thoroughly and consider the advantages and disadvantages, as well as the impact of her decision on the business.

Movement of protistan trophic groups in soil–plant continuums
Authors: Lin Chenshuo , Li Wen‐Jing , Li Li‐Juan , Neilson Roy , An Xin‐Li , Zhu Yong‐Guan 
Published: August 2023

AbstractProtists, functionally divided into consumers, phototrophs, and parasites act as integral components and vital regulators of microbiomes in soil–plant continuums. However, the drivers of community structure, assembly mechanisms, co‐occurrence patterns, and the associations with human pathogens and different protistan trophic groups remain unknown. Here, we characterized the phyllosphere and soil protistan communities associated with three vegetables under different fertilization treatments (none and organic fertilization) at five growth stages. In this study, consumers were the most diverse soil protist group, had the role of inter‐kingdom connector, and were the primary biomarker for rhizosphere soils which were subjected to decreasing deterministic processes during plant growth. In contrast, phototrophs had the greatest niche breadth and formed soil protistan hubs, and were the primary biomarkers for both bulk soils and the phyllosphere. Parasites had minimal input to microbial co‐occurrence networks. Organic fertilization increased the relative abundance (RA) of pathogenic protists and the number of pathogen–consumer connections in rhizosphere soils but decreased protistan richness and the number of internal protistan links. This study advances our understanding of the ecological roles and potential links between human pathogens and protistan trophic groups associated with soil–plant continuums, which is fundamental to the regulation of soil–plant microbiomes and maintenance of environmental and human health.
Bacterial adaptation to cold: Conservation of a short J‐domain co‐chaperone and its protein partners in environmental proteobacteria

AbstractBacterial genomes are a huge reservoir of genes encoding J‐domain protein co‐chaperones that recruit the molecular chaperone DnaK to assist protein substrates involved in survival, adaptation, or fitness. The atc operon of the aquatic mesophilic bacterium Shewanella oneidensis encodes the proteins AtcJ, AtcA, AtcB, and AtcC, and all of them, except AtcA, are required for growth at low temperatures. AtcJ is a short J‐domain protein that interacts with DnaK, but also with AtcC through its 21 amino acid C‐terminal domain. This interaction network is critical for cold growth. Here, we show that AtcJ represents a subfamily of short J‐domain proteins that (i) are found in several environmental, mostly aquatic, β‐ or ɣ‐proteobacteria and (ii) contain a conserved PX7W motif in their C‐terminal extension. Using a combination of NMR, biochemical and genetic approaches, we show that the hydrophobic nature of the tryptophan of the S. oneidensis AtcJ PX7W motif determines the strong AtcJ–AtcC interaction essential for cold growth. The AtcJ homologues are encoded by operons containing at least the S. oneidensis atcA, atcB, and atcC homologues. These findings suggest a conserved network of DnaK and Atc proteins necessary for low‐temperature growth and, given the variation in the atc operons, possibly for other biological functions.
