The glaciers on Africa's ‘Mountains of the Moon' (Rwenzori National Park, Uganda) are predicted to disappear within the next decades owing to climate change. Consequently, the glacier-fed streams (GFSs) that drain them will vanish, along with their resident microbial communities. Despite the relevance of microbial communities for performing ecosystem processes in equatorial GFSs, their ecology remains understudied. Here, we show that the benthic microbiome from the Mt. Stanley GFS is distinct at several levels from other GFSs. Specifically, several novel taxa were present, and usually common groups such as Chrysophytes and
Polaromonas
exhibited lower relative abundances compared to higher-latitude GFSs, while cyanobacteria and diatoms were more abundant. The rich primary producer community in this GFS likely results from the greater environmental stability of the Afrotropics, and accordingly, heterotrophic processes dominated in the bacterial community. Metagenomics revealed that almost all prokaryotes in the Mt. Stanley GFS are capable of organic carbon oxidation, while greater than 80% have the potential for fermentation and acetate oxidation. Our findings suggest a close coupling between photoautotrophs and other microbes in this GFS, and provide a glimpse into the future for high-latitude GFSs globally where primary production is projected to increase with ongoing glacier shrinkage.

survival in response to ciprofloxacin antibiotic stress correlates with increased nucleoid length and effective misfolded protein management
Authors: Butler George , Bos Julia , Austin Robert H. , Amend Sarah R. , Pienta Kenneth J.
Published: August 2023

The evolution of antibiotic resistance is a fundamental problem in disease management but is rarely quantified on a single-cell level owing to challenges associated with capturing the spatial and temporal variation across a population. To evaluate cell biological phenotypic responses, we tracked the single-cell dynamics of filamentous bacteria through time in response to ciprofloxacin antibiotic stress. We measured the degree of phenotypic variation in nucleoid length and the accumulation of protein damage under ciprofloxacin antibiotic and quantified the impact on bacterial survival. Increased survival was correlated with increased nucleoid length and the variation in this response was inversely correlated with antibiotic concentration. Survival time was also increased through clearance of misfolded proteins, an unexpected mechanism of stress relief deployed by the filamentous bacteria. Our results reveal a diverse range of survival tactics employed by bacteria in response to ciprofloxacin and suggest potential evolutionary routes to resistance.

To characterize the impact of major research awards on recipients' subsequent work, we studied Nobel Prize winners in Chemistry, Physiology or Medicine, and Physics and MacArthur Fellows working in scientific fields. Using a case-crossover design, we compared scientists’ citations, publications and citations-per-publication from work published in a 3-year pre-award period to their work published in a 3-year post-award period. Nobel Laureates and MacArthur Fellows received fewer citations for post- than for pre-award work. This was driven mostly by Nobel Laureates. Median decrease was 80.5 citations among Nobel Laureates (
p
= 0.004) and 2 among MacArthur Fellows (
p
= 0.857). Mid-career (42–57 years) and senior (greater than 57 years) researchers tended to earn fewer citations for post-award work. Early career researchers (less than 42 years, typically MacArthur Fellows) tended to earn more, but the difference was non-significant. MacArthur Fellows (
p
= 0.001) but not Nobel Laureates (
p
= 0.180) had significantly more post-award publications. Both populations had significantly fewer post-award citations per paper (
p
= 0.043 for Nobel Laureates, 0.005 for MacArthur Fellows, and 0.0004 for combined population). If major research awards indeed fail to increase (and even decrease) recipients' impact, one may need to reassess the purposes, criteria, and impacts of awards to improve the scientific enterprise.
Autophagy preferentially degrades non-fibrillar polyQ aggregates

Published: August 2023

Aggregation of proteins containing expanded polyglutamine (polyQ) repeats is the cytopathologic hallmark of a group of dominantly inherited neurodegenerative diseases, including Huntington’s disease (HD). Huntingtin (Htt), the disease protein of HD, forms amyloid-like fibrils by liquid-to-solid phase transition. Macroautophagy has been proposed to clear polyQ aggregates, but the efficiency of aggrephagy is limited. Here, we used cryo-electron tomography to visualize the interactions of autophagosomes with polyQ aggregates in cultured cellsin situ. We found that an amorphous aggregate phase exists next to the radially organized polyQ fibrils. Autophagosomes preferentially engulfed this amorphous material, mediated by interactions between the autophagy receptor p62/SQSTM1 and the non-fibrillar aggregate surface. In contrast, amyloid fibrils excluded p62 and evaded clearance, resulting in trapping of autophagic structures. These results suggest that the limited efficiency of autophagy in clearing polyQ aggregates is due to the inability of autophagosomes to interact productively with the non-deformable, fibrillar disease aggregates.
Spastin locally amplifies microtubule dynamics to pattern the axon for presynaptic cargo delivery
Authors: Aiken Jayne , Holzbaur Erika L. F.
Published: August 2023

Neurons rely on long-range trafficking of synaptic components to form and maintain the complex neural networks that encode the human experience. With a single neuron capable of forming thousands of distincten passantsynapses along its axon, spatially precise delivery of the necessary synaptic components is paramount. How these synapses are patterned, and how efficient delivery of synaptic components is regulated, remains largely unknown. Here, we reveal a novel role for the microtubule severing enzyme spastin in locally enhancing microtubule polymerization to influence presynaptic cargo pausing and retention along the axon. In human neurons derived from induced pluripotent stem cells (iPSCs), we identify sites stably enriched for presynaptic components, termed ‘protosynapses’, which are distributed along the axon prior to the robust assembly of mature presynapses apposed by postsynaptic contacts. These sites are capable of cycling synaptic vesicles, are enriched with spastin, and are hotspots for new microtubule growth and synaptic vesicle precursor (SVP) pausing/retention. Disruption of neuronal spastin, either by CRISPRi-mediated depletion or transient overexpression, interrupts the localized enrichment of dynamic microtubule plus ends and diminishes SVP accumulation. Using an innovative human heterologous synapse model, where microfluidically isolated human axons recognize and form presynaptic connections with neuroligin-expressing non-neuronal cells, we reveal that neurons deficient for spastin do not achieve the same level of presynaptic component accumulation as control neurons. We propose a model where spastin acts locally as an amplifier of microtubule polymerization to pattern specific regions of the axon for synaptogenesis and guide synaptic cargo delivery.
Within-host evolution of SARS-CoV-2: how often arede novomutations transmitted?
Authors: Korosec Chapin S. , Wahl Lindi M. , Heffernan Jane M.
Published: August 2023

Despite a relatively low mutation rate, the large number of SARS-CoV-2 infections has allowed for substantial genetic change, leading to a multitude of emerging variants. Using a recently determined mutation rate (per site replication), as well as parameter estimates for within-host SARS-CoV-2 infection, we apply a stochastic transmission-bottleneck model to describe the survival probability ofde novoSARS-CoV-2 mutations. For narrow bottlenecks, we find mutations affecting pertarget-cell attachment rate (with phenotypes associated with fusogenicity and ACE2 binding), have similar transmission probabilities to mutations affecting viral load clearance (with phenotypes associated with humoral evasion). We further find that mutations affecting the eclipse rate (with phenotypes associated with reorganization of cellular metabolic processes and synthesis of viral budding precursor material) are highly favoured relative to all other traits examined. We find mutations leading to reduced removal rates of infected cells (with phenotypes associated with innate immune evasion) have limited transmission advantage relative to mutations leading to humoral evasion. Predicted transmission probabilities, however, for mutations affecting innate immune evasion are more consistent with the range of clinically-estimated household transmission probabilities forde novomutations. This result suggests that although mutations affecting humoral evasion are more easily transmitted when they occur, mutations affecting innate immune evasion may occur more readily. We examine our predictions in the context of a number of previously characterized mutations in circulating strains of SARS-CoV-2. Our work offers both a null model for SARS-CoV-2 substitution rates and predicts which aspects of viral life history are most likely to successfully evolve, despite low mutation rates and repeated transmission bottlenecks.
5-HT 2A and 5-HT 2C receptor antagonism differentially modulates reinforcement learning and cognitive flexibility: behavioral and computational evidence

Published: August 2023

Cognitive flexibility, the ability to adapt behavior in response to a changing environment, is disrupted in several neuropsychiatric disorders, including obsessive–compulsive disorder (OCD) and major depressive disorder (MDD). Evidence suggests that flexibility, which can be operationalized using reversal learning tasks, is modulated by serotonergic transmission. However, how exactly flexible behavior and associated reinforcement learning (RL) processes are modulated by 5-HT action on specific receptors is unknown.

We investigated the effects of 5-HT2Areceptor (5-HT2AR) and 5-HT2Creceptor (5-HT2CR) antagonism on cognitive flexibility and underlying RL mechanisms. Thirty-six male Lister hooded rats were trained on a touchscreen visual discrimination and reversal task. We evaluated the effects of systemic treatments with the 5-HT2AR and 5-HT2CR antagonists M100907 and SB-242084, respectively, on reversal learning performance and performance on probe trials where correct and incorrect stimuli were presented with a third, probabilistically rewarded, stimulus. Computational models were fitted to task choice data to extract RL parameters, including a novel model designed specifically for this task.

5-HT2AR antagonism impaired reversal learning during certain phases. 5-HT2CR antagonism, on the other hand, impaired learning from positive feedback. RL models further differentiated these effects. 5-HT2AR antagonism decreased punishment learning rate at high and low doses. The low dose also increased exploration (beta) and increased stimulus and side stickiness (kappa). 5-HT2CR antagonism also increased beta, but reduced side stickiness.

These data indicate that 5-HT2Aand 5-HT2CRs both modulate different aspects of flexibility, with 5-HT2ARs modulating learning from negative feedback and 5-HT2cRs for learning from positive feedback.

Cardiovascular disease continues to take more human lives than all cancer combined, prompting the need for improved research models and treatment options. Despite a significant progress in development of mature heart-on-a-chip models of fibrosis and cardiomyopathies starting from induced pluripotent stem cells (iPSCs), human cell-based models of myocardial inflammation are lacking. Here, we bioengineered a vascularized heart-on-a-chip system with circulating immune cells to model SARS-CoV-2-induced acute myocarditis. Briefly, we observed hallmarks of COVID-19-induced myocardial inflammation in the heart-on-a-chip model, as the presence of immune cells augmented the expression levels of proinflammatory cytokines, triggered progressive impairment of contractile function and altered intracellular calcium transient activities. An elevation of circulating cell-free mitochondrial DNA (ccf-mtDNA) was measured first in thein vitroheart-on-a-chip model and then validated in COVID-19 patients with low left ventricular ejection fraction (LVEF), demonstrating that mitochondrial damage is an important pathophysiological hallmark of inflammation induced cardiac dysfunction. Leveraging this platform in the context of SARS-CoV-2 induced myocardial inflammation, we established that administration of human umbilical vein-derived EVs effectively rescued the contractile deficit, normalized intracellular calcium handling, elevated the contraction force and reduced the ccf- mtDNA and chemokine release via TLR-NF-kB signaling axis.
Synthesis, crystal structure and Hirshfeld surface analysis of a copper(II) complex involving 3-methylbenzoate and 2,2′-bipyridine ligands
Authors: Qadir Adnan
Published: August 2023

3-Methylbenzoic acid (3-mbH) and 2,2′-bipyridine (bipy) reacted with a copper(II) salt forming a new mixed ligand complex, aqua(2,2′-bipyridine-κ2
N,N′)bis(3-methylbenzoato)-κ2
O,O′;κO-copper(II) 0.68-hydrate, [Cu(C8H7O2)2(C10H8N2)(H2O)]·0.68H2O or [Cu(3-mb)2(bipy)(H2O)]·0.68H2O. The coordination environment of CuII is a distorted octahedron. The metal atom is attached to two 3-mb moieties, which bind in monodentate and bidentate fashions. One of the 3-mb units is disordered. The coordination environment is completed by one bipy ligand and a water molecule. A second water molecule is outside the coordination sphere of the CuII atom and its occupancy refined to 0.68. The structure consists of chains along the b-axis direction formed by complex units joined via hydrogen bonds between the coordinated water molecule and an O atom of a coordinated 3-mb unit. Hirshfeld surface analysis indicates that the most abundant contacts are H...H (56.8%), H...C/C...H (21.7%) and H...O/O...H (13.7%).
Enterprise digital transformation under process constraints: investigation of the combinative effects of different constraints
Authors: Lei Hui , Tang Shiyi , Zan Ao
Published: August 2023

Purpose

This study aims to empirically study the effect of process constraints and the combinative effects of different constraints on enterprise digital transformation.

Design/methodology/approach

This paper selects the World Bank's business environment survey of Chinese enterprises in 2012 as the research sample to empirically study the effect of process constraints and different kinds of constraints on enterprise digital transformation.

Findings

The authors find that process constraints have an inverted U-shaped effect on enterprise digital transformation and that employee digital literacy plays an intermediary role in this process. That is, process constraints have a too-much-of-a-good-thing effect on employees' digital literacy, which further affects enterprise digital transformation. The increase in the number of input and output constraints will make the inverted U-shaped relationship between the process constraint and digital transformation steeper.

Originality/value

The constraints faced by enterprises are everywhere and of many kinds. This paper not only discusses the influence of process constraints on enterprise digital transformation but also analyzes the interactive influence of different kinds of constraints on enterprise digital transformation and explores its micromechanism. This approach is helpful for enterprise managers in thinking about how to make full use of different kinds of constraints to activate the power of enterprise digital transformation, regard constraints as challenges and opportunities, and use them to stimulate the ability to improve the resource integration and utilization.
Restaurant menus and COVID-19: implications for technology adoption in the post-pandemic era
Authors: Iskender Ali , Sirakaya-Turk Ercan , Cardenas David
Published: August 2023

Purpose

This paper aims to systematically explore the experiences of restaurant patrons with quick response (QR) code menus during the pandemic to extract insights pertaining to the acceptance of technology adoption in service settings for the post-COVID era.

Design/methodology/approach

COVID-19 has enormously impacted consumer perceptions toward technology adoption in restaurants. Identifying these impacts requires qualitative inquiries because qualitative techniques, unlike quantitative methods, enable researchers to seek insights into the phenomenon without a predetermined stance. This study applied a qualitative research method. The qualitative data was obtained through in-depth interviews and a focus group. Thematic analysis was conducted.

Findings

This study identified perceived attributes of QR code technology by patrons: positive attributes such as easy to learn, quick and contactless; and negative attributes such as effortful and reliance on a smartphone. Also, the results distinguished perceived advantages of utilization of QR codes as restaurants’ menu: advantages such as hygienic, environmentally friendly due to no printing and contactless; and disadvantages such as poor menu design and lack of interaction.

Practical implications

This research presents patrons’ views on QR code menu utilization at restaurants under the pandemic conditions. Contradictory responses on the same features of technology reveal a lack of menu design in the utilization of QR codes. Restaurant practitioners can extract insights about how to better use technology like QR codes, cost-effective and environmentally friendly, in their operations in the postpandemic era.

Originality/value

This study included both deductive and inductive approaches. An inductive approach that progressed from theory to data was applied while forming interview questions. A deductive approach was used to inform theory with the findings of the data. The value of research derives from differentiating technology attributes (QR codes) and utilization domain (restaurant menu) in the realm of acceptance of technology in the consumer context.
Evaluating magnetic fields using deep learning
Authors: Rahman Mohammad Mushfiqur , Khan Arbaaz , Lowther David , Giannacopoulos Dennis
Published: August 2023

Purpose

The purpose of this paper is to develop surrogate models, using deep learning (DL), that can facilitate the application of EM analysis software. In the current status quo, electrical systems can be found in an ever-increasing range of products that are part of everyone’s daily live. With the advances in technology, industries such as the automotive, communications and medical devices have been disrupted with new electrical and electronic systems. The innovation and development of such systems with increasing complexity over time has been supported by the increased use of electromagnetic (EM) analysis software. Such software enables engineers to virtually design, analyze and optimize EM systems without the need for building physical prototypes, thus helping to shorten the development cycles and consequently cut costs.

Design/methodology/approach

The industry standard for simulating EM problems is using either the finite difference method or the finite element method (FEM). Optimization of the design process using such methods requires significant computational resources and time. With the emergence of artificial intelligence, along with specialized tools for automatic differentiation, the use of DL has become computationally much more efficient and cheaper. These advances in machine learning have ushered in a new era in EM simulations where engineers can compute results much faster while maintaining a certain level of accuracy.

Findings

This paper proposed two different models that can compute the magnetic field distribution in EM systems. The first model is based on a recurrent neural network, which is trained through a data-driven supervised learning method. The second model is an extension to the first with the incorporation of additional physics-based information to the authors’ model. Such a DL model, which is constrained by the laws of physics, is known as a physics-informed neural network. The solutions when compared with the ground truth, computed using FEM, show promising accuracy for the authors’ DL models while reducing the computation time and resources required, as compared to previous implementations in the literature.

Originality/value

The paper proposes a neural network architecture and is trained with two different learning methodologies, namely, supervised and physics-based. The working of the network along with the different learning methodologies is validated over several EM problems with varying levels of complexity. Furthermore, a comparative study is performed regarding performance accuracy and computational cost to establish the efficacy of different architectures and learning methodologies.
Value co-creation via machine learning from a configuration theory perspective
Authors: Presti Claudia , De Santis Federica , Bernini Francesca
Published: August 2023

Purpose

This paper aims to propose an interpretive framework to understand how machine learning (ML) affects the way companies interact with their ecosystem and how the introduction of digital technologies affects the value co-creation (VCC) process.

Design/methodology/approach

This study bases on configuration theory, which entails two main methodological phases. In the first phase the authors define the theoretically-derived interpretive framework through a literature review. In the second phase the authors adopt a case study methodology to inductively analyze the theoretically-derived domains and their relationships within a configuration.

Findings

ML enables multi-directional knowledge flows among value co-creators and expands the scope of VCC beyond the boundaries of the firm-client relationship. However, it determines a substantive imbalance in knowledge management power among the actors involved in VCC. ML positively impacts value co-creators’ performance but also requires significant organizational changes. To benefit from VCC via ML, value co-creators must be aligned in terms of digital maturity.

Originality/value

The paper answers the call for more theoretical and empirical research on the impact of the introduction of Industry 4.0 technology in companies and their ecosystem. It intends to improve the understanding of how ML technology affects the determinants and the process of VCC by providing both a static and dynamic analysis of the topic.
Manifestations of leadership identity development among multicultural higher education students
Authors: Ramamoorthi Bhavani , Jäppinen Aini-Kristiina , Taajamo Matti
Published: August 2023

Purpose

This study aims to examine how leadership identity manifests at the individual and collective levels within a relational training context among a group of multicultural higher education students.

Design/methodology/approach

This is a case study and examines the interactions among eight multicultural students through the theoretical lens of leadership identity development (LID) theory.

Findings

The main findings of this study suggest that LID manifests through an open will and intensifying motivation to the collective impulse of achieving shared goals through nurturing the collective cognition to integrate diverse perspectives and a broadening view of leadership as a collective capacity for co-creation and generativity.

Research limitations/implications

Although the paper builds on a case study with a limited number of participants and the ability to generalise its findings is partial, the study may provide practical applications for training leadership in other collaborative contexts and supporting it at the individual and collective levels.

Originality/value

The LID theory and LID model have been applied simultaneously to a training lab to examine how LID manifests among a multicultural group of higher education students. The lab emphasises a participatory leadership-oriented pedagogy.
Do employees’ perceptions of diversity management enhance firm’s financial performance: the moderating role of board members’ diversity level
Authors: Lim Juhwan , Vaughan Yue , Jang Jichul
Published: August 2023

Purpose

The hospitality industry has one of the most diversified workforces. This study aims to examine the effect of employees’ perceptions toward diversity management on the company’s financial performance. The current study also examines the moderating effect of board members’ diversity level on the association between employees’ perceptions and financial outcomes.

Design/methodology/approach

From online reviews, the authors identified multi-faucets of diversity management and measured employees’ perceptions of diversity management. Using panel data analysis, the relationships among employees’ perceptions, board members’ diversity level and companies’ financial performance were studied.

Findings

This study found that employees’ perceptions of diversity management positively influence the company’s financial performance and the relationship was positively moderated by board members’ diversity level.

Practical implications

Findings show that hospitality employees perceive nine diversity and inclusion categories (age, organizational climate, culture, disability, education, gender, physical differences, policy and practice and race) that companies need to consider when developing and implementing diversity management. Moreover, practitioners need to eliminate the gap between board members and employees when applying diversity management.

Originality/value

Drawing upon service–profit chain theory, this study extends hospitality literature regarding diversity management by demonstrating how employees perceive working environments created by diversity management affects the organizational financial outcome. Moreover, this study emphasizes the exemplary role of board members as policy and practice makers, to provide employees with the legitimacy and responsibilities of diversity management.
How CEO responsible leadership shapes corporate social responsibility and organization performance: the roles of organizational climates and CEO founder status
Authors: Wang Zhao , Ye Yijiao , Liu Xuefeng
Published: August 2023

Purpose

This paper aims to investigate how chief executive officer (CEO) responsible leadership impacts corporate social responsibility (CSR) and organization performance by considering diverse organizational climates (including ethical, service and initiative climates) as mediators and CEO founder status as a moderator.

Design/methodology/approach

This study analyzed survey data from 212 service organizations in China with structural equation modeling.

Findings

The results clearly established that CEO responsible leadership played a crucial role in augmenting both CSR and organization performance by shaping positive organizational climates. Notably, CEO responsible leadership significantly fostered ethical, service and initiative climates. Furthermore, an ethical climate promoted CSR and organization performance, whereas service and initiative climates specifically enhanced organization performance. Additionally, responsible CEOs with founder status exhibited a higher propensity for enhancing ethical, service and initiative climates within service organizations.

Practical implications

Service organizations should take measures to build CEO responsible leadership, especially for CEOs with founder status. Furthermore, service organizations should motivate employees to reach consensus on ethical conducts, superior service and proactive approach to work.

Originality/value

First, the findings on CEO responsible leadership’s effects on CSR and organization performance extend the research on responsible leadership outcomes. Second, this paper adds to responsible leadership literature through exploring the mediating effects of ethical, service and initiative climates. Finally, the finding on the moderating role of founder CEOs offers a novel perspective regarding the boundary condition of the effects of CEO responsible leadership.
Social capital-based strategy of sustainable village-owned enterprises (BUMDes) development
Authors: Rahayu Murtanti Jani , Mukaromah Hakimatul , Mulyanto Mulyanto
Published: August 2023

Purpose

The Indonesian government's Village-Owned Enterprises (BUMDes) initiative optimizes Village Resources (SDD)—human and natural—to improve rural communities' welfare. Villagers must participate in many ways. Due to its natural potential, industry, waste management and building management business units, BUMDes Waskito Wijaya in Waru village, Baki sub-district, Sukoharjo Regency, Central Java has the potential to grow. Strengthening social capital helps BUMDes management become sustainable.

Design/methodology/approach

The focus of this research is to find out what social capital characteristics that can improve the development of BUMDes Waskito Wijaya. Thus, this study uses a SWOT analysis to establish BUMDes by promoting village influencers, strong institutions, and internal and external social networks. Thus, strong bonding, linking and bridging will improve BUMDes' involvement in the village. This research describes the organization's internal and external situations and formulates the BUMDes development strategy empirically.

Findings

This study revealed that norms, trust, social networks and infrastructure positively impact BUMDes development. However, the social capital created is still in the bonding stage. While the linking and bridging stages are not yet sufficient to support a productive and prosperous BUMDes.

Originality/value

Thus, the developed strategy encourages the strong leadership spirit of the village influencers, creates aspirational and supportive institutions, and strengthens social networks both horizontally and vertically. Consequently, the linking and bridging that can actively engage in partnerships and build public trust will successfully be achieved. The condition will develop the capacity of BUMDes in providing facilities for the community.

A new fault diagnosis of rolling bearing based on phase-space reconstruction and convolutional neural network
Authors: Wang Mengjiao , Ding Liting
Published: August 2023

Purpose

To solve the problem that the traditional methods miss key information in the process of bearing fault identification, this paper aims to apply the phase-space reconstruction (PSR) theory and intelligent diagnosis techniques to extend the one-dimensional vibration signal to the high-dimensional phase space to reveal the system information implied in the univariate time series of the vibration signal.

Design/methodology/approach

In this paper, a new method based on the PSR technique and convolutional neural network (CNN) is proposed. First, the delay time and the embedding dimension are determined by the C-C method and the false nearest neighbors method, respectively. Through the coordinate delay reconstruction method, the two-dimensional signal is constructed, and this information is saved in a set of gray images. Then, a simple and efficient convolutional network is proposed. Finally, the phase diagrams of different states are used as samples and input into a two-dimensional CNN for learning modeling to construct a PSR-CNN fault diagnosis model.

Findings

The proposed PSR-CNN model is tested on two data sets and compared with support vector machine (SVM), k-nearest neighbor (KNN) and Markov transition field methods, and the comparison results showed that the method proposed in this paper has higher accuracy and better generalization performance.

Originality/value

The method proposed in this paper provides a reliable solution in the field of rolling bearing fault diagnosis.

Bringing safety analytics to the online shopper: evaluating designs for augmenting point-of-sale interfaces with safety information
Authors: Gruss Richard , Goldberg David , Zaman Nohel , Abrahams Alan
Published: August 2023

Purpose

The widespread adoption of online purchasing has prompted increasing concerns about product safety, and regulators are beginning to hold e-commerce sites accountable for dangerous product defects. For online consumers, understanding the many inherent safety risks among the extensive array of products they browse is a formidable task. The authors attempt to address this problem via a client-side software artifact that warns shoppers about potential product safety hazards at the point of sale.

Design/methodology/approach

In this study, the authors built four candidate designs and assessed their effectiveness by means of a large randomized controlled experiment (n = 466). The authors define effectiveness as significant changes in dependent variables associated with health behaviors and technology adoption.

Findings

The authors find that all of the designs score high on adoption likelihood, that designs incorporating highlighting and scoring are better at increasing safety knowledge and that simpler designs are better at enhancing safety awareness.

Originality/value

These findings will inform the design of safety information dissemination systems and open new areas of safety awareness enhancement research. More generally, the authors introduce a novel method of testing text visualization variations and their impact on behavioral decisions.
Knowledge sharing in family SMEs: the role of communities of practice
Authors: Rossignoli Francesca , Lionzo Andrea , Henschel Thomas , Boers Börje
Published: August 2023

Purpose

The aim of this paper is to analyse the role of communities of practice (CoP) as knowledge-sharing tools in family small and medium-sized enterprises (SMEs). In this context, CoPs that jointly involve family and non-family members are expected to act as knowledge-sharing tools.

Design/methodology/approach

This paper employs a multiple case study methodology, analysing the cases of six small companies in different sectors and countries over a period of 8 years. Both primary and secondary data are used.

Findings

The results show the role CoPs play in involving family and non-family members in empowering knowledge-sharing initiatives. A CoP's role in knowledge sharing depends on the presence (or lack) of a family leader, the leadership approach, the degree of cohesion around shared approaches and values within the CoP, and the presence of multiple generations at work.

Originality/value

This paper contributes to the literature on knowledge sharing in family businesses, by exploring for the first time the role of the CoP as a knowledge-sharing tool, depending on families' involvement in the CoP.
The features of Anglican churches in Malaysia and their maintenance practices
Authors: Ow Wee Fhong , Chua Shirley Jin Lin , Ali Azlan Shah
Published: August 2023

Purpose

This paper aims to explore the history of Anglican churches in Malaysia and discusses their typical features and their respective maintenance practices.

Design/methodology/approach

A narrative review of 84 literacy sources published between 1967 and 2020 on the development and features of Anglican churches in Malaysia, along with recommendations on maintenance practices from the asset and facilities management perspective. The exploration of churches’ features follows three main disciplines in building maintenance according to the Jabatan Kerja Raya Guideline for as-built buildings in Malaysia.

Findings

The findings of the study have then been tabulated to form a maintenance framework to recommend suitable maintenance practices on specific building components based on different materials. The paper argues that as places of worship, the assets of religious facilities are intangible compared to any other types of building that serve a tangible function (i.e. shelter, commercial or industrial operation). Throughout the exploration of their maintenance practices suggested by vast sources of literature, it is proven that the maintenance of churches is not as straightforward as merely remedying the defects, but it requires the maintenance to radically minimise any disturbance to their aesthetics, thus making maintenance a more challenging task at churches.

Originality/value

This paper proposes a maintenance framework for Anglican churches in Malaysia by categorising building disciplines and their corresponding building components, which supports future research to improve the maintenance practices of religious facilities.
Dimension of community capability and its effect on the social vulnerability at Semarang coastal area
Authors: Yuliastuti Nany , Okta Ega Varian , Haryanti Vica Gitya , Afif Farhan
Published: August 2023

Purpose

Tanjung Mas, an urban village located in the northern part of Semarang city, has been facing a major impact of coastal inundation occurring along North Java Coastline. This by-product of global climate change is also affecting a 37-hectares slum, one of the largest slums in Semarang city. As the coastal flood tends to escalate every year, the affected areas must have a coping ability to reduce its impact, while also having adequate resources to recover. Considering Tanjung Mas’ dense demographic condition and its function as the city’s seaport, social vulnerability and capability play a significant role in mitigating and recovering flood impacts, in supplement to local government’s effort of strengthening the Northern Java Seawall. Therefore, this study aims to scored and correlated Tanjung Mas’ social vulnerability index (SoVI) and community capability index to assess how well its population can recover from the tidal flood in the future.

Design/methodology/approach

This study used the SoVI framework analysis to synthesize relevant social vulnerability indicators and community capability indicators in Tanjung Mas. The two sets of indicators were correlated with Pearson R-squared correlation method to seek a possible non-causal relation. Bivariate indices mapping method exhibit the SoVI and community capability index spatially to show every area’s vulnerability and capability level.

Findings

The vulnerability and capability level in Tanjung Mas vary within its smaller area, as six combinations of social vulnerability and community capability level were found. The worst combination was found on areas closer to the coastline, with high social vulnerability and low community capability level. These areas need to be strengthened in both its capability and coping ability toward coastal flood to realize a resilient community.

Originality/value

This study will be useful for local governments as a supplement to the strategic spatial plan, predominantly in prioritizing vulnerable area treatment prior to the completion of Northern Java Seawall in 2025. This study provides information and a simplified quantitative scoring result of vulnerability and capability level in slum area that has been customized according to Indonesia’s demographic characteristic. These results and framework might be relevant to SoVI and capability scoring in developing countries.
From craft to industry and back: transnational efforts in reconstructing tin’s social meaning to the retail consumer (1950s–1960s)
Authors: Yong Yen Nie
Published: August 2023

Purpose

Commodity histories generally posit colonies’ roles as mere producers but have overlooked their roles in shaping global consumption. This study aims to investigate how Malayan tin producers and British colonial institutions used public relations and advertising strategies as entrepreneurial tools to fend off competition from substitutes amid global economic and geopolitical transitions during the height of the Cold War crisis and post-war boom in the 1950s and 1960s.

Design/methodology/approach

This study draws on archival research of newspaper reports written in Singapore, the USA and Britain from the inter-war years until the 1960s. It also consults advertisements placed by the Malayan Tin Bureau on Time and Scientific American, data and views on tin scarcity by US congressional reports and commodity trends data published by the US Department of Commerce and the US Department of the Interior.

Findings

This paper demonstrates how the value of tin is recreated by manipulating its symbolic meanings and embedding them within the national and political contexts of the targeted consumer markets. This creative resistance against tin substitution was enacted through a transnational collaboration among colonial institutions, entrepreneurs in colonies and marketing strategists across geographies and territories.

Research implications

This paper provokes further reflections on the importance of socially constructed meanings in shaping the market value of a product and the understanding of embedded political value systems in marketing generic commodities. Future research may adopt this perspective to reassess the framing of meanings of commodities in the contemporary setting, especially against rising concerns on the sustainability of mining natural resources, including minerals.

Originality

This study integrates the perspectives of Malayan tin producers in reframing the meaning of a commodity and so, widens the scope of historical analyses of commodities beyond the industrialized global North. It reassesses how a commodity’s marketing value evolves and interacts with colonial politics. It also highlights the collaborative nature of colonial governments and local producers in developing new uses and representations of a generic commodity to create new markets for its consumption.
Emerging from the chaos of Management Theory Jungle: a historical analysis of the development of the four principles of management
Authors: Lloyd Robert , Mertens Daniel , Pálka Přemysl , Villegas Salvador
Published: August 2023

Purpose

This paper aims to map the antecedents and precursory contexts regarding the four principles of management. Moreover, a description of its codification and coalescence as a unified teaching framework is provided, critically reviewing key theoretical underpinnings of management principles in academic research and management textbooks.

Design/methodology/approach

A historiographic approach reviewed seminal works for theory origins of the four principles of management, by analyzing 260 management textbooks from 1935 to 2013 to document their adoption in management education. This study used critical hermeneutics (Prasad, 2002) to explore the framework’s progression by providing the context of cultural, political and economic influences.

Findings

This research study tracked and mapped the creation of the four principles of management, as it became the commonly accepted teaching framework in management education. Today, every predominant management principles textbook uses the four principles of management – plan, lead, organize and control – as the basis for teaching students.

Research limitations/implications

There is limited research on the application of the four principles of management in contemporary management, despite its ubiquity in management education. The study’s historical account of its formation provides insights into its adoption and utilization in modern education context. The study’s primary limitation stems from the generalization of the representative sample of textbooks used in the study (1917–2013). However, data saturation was achieved for the scale of textbooks and writings which was reviewed.

Originality/value

Through a critical analysis into the formation of the four principles of management, this research not only provides a historical account of its construction but, as importantly, the influencing factors that led to its development. This research fills a gap in critical literature, as a post mortem exegesis has never been conducted on the four principles of management in the afteryears of its amalgamation.
Structural deterrents of combating white-collar money laundering in emerging economies: evidence from Sri Lanka
Authors: Jayasekara Sisira Dharmasri , Perera K.L. Wasantha , Ajward Roshan
Published: August 2023

Purpose

The purpose of this paper is to discuss how agency conflicts between people and main government organs affect the combatting ability of white-collar money laundering in an emerging economy.

Design/methodology/approach

This paper uses a qualitative design under the philosophy of interpretivism. The case study research strategy is used inductively to investigate how structural limitations affect white-collar money laundering.

Findings

This study reveals that serious agency conflicts exist between public and main government organs which are detrimental to the rights of people to enjoy a crime-free society. First agency conflict of people and legislature intensifies as a result of limited understanding of the legislature and failure to take precautionary actions to develop an anti-money laundering and countering the financing of terrorism (AML/CFT) regime with evolving global standards. This delay has resulted in identifying Sri Lanka as a deficient AML/CFT regime twice. The second conflicts arise between people and the executive which is a serious conflict due to misuse of statutory power and failure to perform duties. The independence and integrity of administrative authorities who perform executive functions were inherent problems of implementing a sound AML/CFT regime. Lack of monitoring, nonavailability of an independent audit and inappropriate reporting channels were other encouraging factors of administrative organs to misuse statutory power. The third conflict between people and the judiciary was not intensified because the function was not so exposed to create agency conflicts. After all, an adequate number of cases had not proceeded to the judiciary due to inherent limitations as a result of intensified first two agency conflicts. The agency conflicts have intensified over the years and AML/CFT regime has been ineffective as a result of limited influence and understanding of the principal, people. Therefore, the principal has to influence the agents to make reforms in the AML/CFT regime to make the country a white-collar crime-free country.

Research limitations/implications

This study uses a case study strategy to assess the context of Sri Lanka as an emerging economy. It is recommended to take into consideration the contextual facts when the findings are applied to other jurisdictions.

Originality/value

This paper is an original work of the authors which discusses how agency conflicts arise between people and three main government organs in implementing a sound AML/CFT regime in Sri Lanka as an emerging economy.
