Published: September 2023

A facultative anaerobic, Gram-strain-negative, rod-shaped bacterium (strain NBU2970T) was isolated by using modified ichip in situ cultivation from a marine sediment sample collected from Meishan Island in the East China Sea. Strain NBU2970T grew optimally at 37 °C, with a NaCl concentration of 2.0 % (w/v) and at pH 7.0. The 16S rRNA gene sequence analyses revealed that strain NBU2970T represents a novel species with the genus

Muricauda

, sharing highest sequence identities with

Muricauda beolgyonensis

BB-My12T (96.1 %),

Muricauda alvinocaridis

SCR12T (96.0 %),

Muricauda taeanensis

105T (96.0 %) and

Muricauda ruestringensis

B1T (95.6 %). Phylogenetic analyses also indicated that strain NBU2970T clustered with the genus

Muricauda

and was closely related to

M. beolgyonensis

BB-My12T and

M. ruestringensis

B1T. The draft genome sequence of strain NBU2970T was composed of six contigs with a size of 3.2 Mbp, containing 3045 protein-coding genes and 38 RNA genes. The DNA G+C content was 43.8 mol%. The average nucleotide identity and digital DNA–DNA hybridization values between strain NBU2970T and related species of the genus

Muricauda

were well below the threshold limit for prokaryotic species delineation. The major cellular fatty acids were iso-C15 : 0, iso-C15 : 1 G and iso-C17 : 0 3-OH. The only respiratory quinone was MK-6. The major polar lipid was phosphatidylethanolamine. Based on its phenotypic, chemotaxonomic and genotypic data, strain NBU2970T is considered to be a representative of a novel species in the genus

Muricauda

, for which the name Muricauda meishanensis sp. nov. is proposed. The type strain is NBU2970T (=KCTC 82915T=MCCC 1K06394T).

Salmonella

are extremely diverse and different serovars can exhibit varied phenotypes, including host adaptation and the ability to cause clinical illness in animals and humans. In the USA,

Salmonella enterica

serovar Kentucky is infrequently found to cause human illness, despite being the top serovar isolated from broiler chickens. Conversely, in Europe, this serovar falls in the top 10 serovars linked to human salmonellosis. Serovar Kentucky is polyphyletic and has two lineages, Kentucky-I and Kentucky-II; isolates belonging to Kentucky-I are frequently isolated from poultry in the USA, while Kentucky-II isolates tend to be associated with human illness. In this study, we analysed whole-genome sequences and associated metadata deposited in public databases between 2017 and 2021 by federal agencies to determine serovar Kentucky incidence across different animal and human sources. Of 5151 genomes, 90.3 % were from isolates that came from broilers, while 5.9 % were from humans and 3.0 % were from cattle. Kentucky-I isolates were associated with broilers, while isolates belonging to Kentucky-II and a new lineage, Kentucky-III, were more commonly associated with cattle and humans. Very few serovar Kentucky isolates were associated with turkey and swine sources. Phylogenetic analyses showed that Kentucky-III genomes were more closely related to Kentucky-I, and this was confirmed by CRISPR-typing and multilocus sequence typing (MLST). In a macrophage assay, serovar Kentucky-II isolates were able to replicate over eight times better than Kentucky-I isolates. Analysis of virulence factors showed unique patterns across these three groups, and these differences may be linked to their association with different hosts.

Generation of mature cells from progenitors requires tight coupling of differentiation and metabolism. During erythropoiesis, erythroblasts are required to massively upregulate globin synthesis then clear extraneous material and enucleate to produce erythrocytes1–3.Nprl3has remained in synteny with the α-globin genes for >500 million years4, and harbours the majority of the α-globin enhancers5. Nprl3 is a highly conserved inhibitor of mTORC1, which controls cellular metabolism. However, whether Nprl3 itself serves an erythroid role is unknown. Here, we show that Nprl3 is a key regulator of erythroid metabolism. Using Nprl3-deficient fetal liver and adult competitive bone marrow - fetal liver chimeras, we show that NprI3 is required for sufficient erythropoiesis. Loss of Nprl3 elevates mTORC1 signalling, suppresses autophagy and disrupts erythroblast glycolysis and redox control. Human CD34+ progenitors lacking NPRL3 produce fewer enucleated cells and demonstrate dysregulated mTORC1 signalling in response to nutrient availability and erythropoietin. Finally, we show that the α-globin enhancers upregulateNprI3expression, and that this activity is necessary for optimal erythropoiesis. Therefore, the anciently conserved linkage ofNprI3, α-globin and their associated enhancers has enabled coupling of metabolic and developmental control in erythroid cells. This may enable erythropoiesis to adapt to fluctuating nutritional and environmental conditions.

Published: September 2023

Members of the genusVibrioare ecologically significant bacteria native to aquatic ecosystems globally, and a few can cause diseases in humans. Vibrio-related illnesses have increased in recent years, primarily attributed to changing environmental conditions. Therefore, understanding the role of environmental factors in the occurrence and growth of pathogenic strains is crucial for public health. Water, oyster, and sediment samples were collected between 2009 and 2012 from Chester River and Tangier Sound sites in Chesapeake Bay, Maryland, USA, to investigate the relationship between water temperature, salinity, and chlorophyll with the incidence and distribution ofVibrio parahaemolyticus(VP) andVibrio vulnificus(VV). Odds ratio analysis was used to determine association between the likelihood of VP and VV presence and these environmental variables. Results suggested that water temperature threshold of 20°C or higher was associated with an increased risk, favoring the incidence ofVibrio spp. A significant difference in salinity was observed between the two sampling sites, with distinct ranges showing high odds ratio forVibrioincidence, especially in water and sediment, emphasizing the impact of salinity on VP and VV incidence and distribution. Notably, salinity between 9-20 PPT consistently favored theVibrioincidence across all samples. Relationship between chlorophyll concentrations and VP and VV incidence varied depending on sample type. However, chlorophyll range of 0-10 µg/L was identified as critical in oyster samples for both vibrios. Analysis of odds ratios for water samples demonstrated consistent outcomes across all environmental parameters, indicating water samples offer a more reliable indicator ofVibrio spp.incidence.

Importance

Understanding the role of environmental parameters in the occurrence ofVibriospecies posing significant public health risks and economic burdens such asVibrio parahaemolyticusandVibrio vulnificusare of paramount importance. These aquatic bacteria are responsible for various human diseases, including gastroenteritis and wound infections, which can be severe and sometimes fatal. Recent observations suggest that certain environmental conditions may favor the growth ofVibrio, leading to more severe disease outcomes. By investigating the environmental factors that influence the occurrence ofVibrio parahaemolyticusandVibrio vulnificus, the need to gain insights into the favorable ranges of environmental variables is apparent. The significance of this research is in identifying the favorable ranges of environmental and ecological factors, which holds the potential to provide an aid in the intervention and mitigation strategies through the development of predictive models, ultimately enhancing our ability to manage and control diseases caused by these pathogens.

Published: September 2023

The recreational use of fentanyl in combination with xylazine (i.e., “tranq-dope”) represents a rapidly emerging public health threat characterized by significant toxicity and mortality. This study quantified the interactions between these drugs on lethality and examined the effectiveness of potential rescue medications to prevent a lethal overdose. Male and female mice were administered acute doses of fentanyl, xylazine, or their combination via intraperitoneal injection, and lethality was determined 30, 60, 90, 120, and 1440 min (24 hr) after administration. Both fentanyl and xylazine produced dose-dependent increases in lethality when administered alone. A nonlethal dose of fentanyl (56 mg/kg) produced an approximately 5-fold decrease in the estimated LD50for xylazine (i.e., the dose estimated to produce lethality in 50% of the population). Notably, a nonlethal dose of xylazine (100 mg/kg) produced an approximately 100-fold decrease in the estimated LD50for fentanyl. The opioid receptor antagonist, naloxone (3 mg/kg), but not the alpha-2 adrenergic receptor antagonist, yohimbine (3 mg/kg), significantly decreased the lethality of a fentanyl-xylazine combination. Lethality was rapid, with death occurring within 10 min after a high dose combination and generally within 30 min at lower dose combinations. Males were more sensitive to the lethal effects of fentanyl-xylazine combinations under some conditions, suggesting biologically relevant sex differences in sensitivity to fentanyl-xylazine lethality. These data provide the first quantification of the lethal effects of “tranq-dope” and suggest that rapid administration of naloxone may be effective at preventing death following overdose.
The impact of different components of HRM strength on employee burnout: a two-wave study
Authors: Xiao Qijie , Liang Xiaoyan
Published: September 2023

Purpose

Most prior studies treated human resource management (HRM) strength as a whole, while neglecting the dynamic interactions between distinct components (consensus, consistency and distinctiveness). The authors lack a deep understanding of how different components operate together to influence burnout. To address these gaps, this study aims to adopt signaling theory to investigate the interactions among different components and their impacts on employee burnout.

Design/methodology/approach

The authors collected time-lagged data from 231 full-time employees in manufacturing firms in Suzhou, China. The authors used the PROCESS Model 6 and hierarchical multiple regression to analyze the data.

Findings

This study found that HRM system consensus and consistency mitigate employee burnout, whereas HRM distinctiveness is not significantly related to burnout. Furthermore, the authors revealed that HRM system consistency (rather than distinctiveness) mediated the relationship between consensus and burnout. Moreover, the authors found the sequential mediating effects of HRM system distinctiveness and consistency on the association between consensus and burnout.

Practical implications

Considering that employees’ well-being problems may be debilitating and overwhelming during the COVID-19 pandemic, it is particularly ethical and timely for managers to direct attention to the role of HRM system strength in addressing employee burnout.

Originality/value

This study advances the HRM system literature by teasing out the interactions between the three pivotal components of HRM strength. Our study is among the first to empirically investigate the internal relationships between the meta-features of the HRM system and employee burnout. In doing so, the authors develop a more nuanced understanding of the collective nature of a strong HRM system that conveys a shared message about HRM to promote well-being.
Symbolic or substantive CSR: effect of green mergers and acquisitions premium on firm value in China
Authors: Liu Ning , Zhou Linyu , Xu LiPing , Xiang Shuwei
Published: September 2023

Purpose

As the cost of completing a transaction, the green merger and acquisition (M&A) premium paid on mergers can influence whether the acquisition creates value or not. However, studies linking M&A premiums to firm value have had mixed results, even fewer studies have examined the effect of green M&A premiums on bidders’ firm value. The purpose of this paper is to investigate whether and how green M&A premiums affect firm value in the context of China’s heavy polluters.

Design/methodology/approach

Using 323 deals between 2008 and 2019 among China’s heavy polluters, this paper estimates with correlation analysis and multiple regression analysis.

Findings

Green M&A premiums are negatively associated with firm value. The results are more significant when firms adopt symbolic rather than substantive corporate social responsibility (CSR) strategies. Robustness and endogeneity tests corroborate the findings. The negative relation is stronger when acquiring firms have low governmental subsidy and environmental regulation, when firms have overconfident management, when firms are state-owned and when green M&A occurs locally or among provinces in the same region. This study also analyzes agency cost as an intermediary in the relationship between green M&A premium and firm value, which lends support to the agency-view hypothesis.

Originality/value

This study provides systemic evidence that green M&A premiums damage firm value through agency cost channel and the choice of CSR strategies from the perspective of acquirers. These findings enrich the literature on both the economic consequences of green M&A premiums and the determinants of firm value and provide a plausible explanation for mixed findings on the relationship between green M&A premiums and firm value.
Oil price fluctuations and economic growth–banking sector nexus: modeling for MENA countries
Authors: Belkhaoui Samir
Published: September 2023

Purpose

The aim of this paper is to evaluate empirically the impact of oil price fluctuations on the relationship between banking sector development and economic growth in oil-importing MENA countries.

Design/methodology/approach

The study used the newly developed panel autoregressive distributed lagged (ARDL) approach in order to address any potential endogeneity between research variables.

Findings

The empirical results show a unidirectional causality in the long run from oil price to both economic growth and banking sector development for oil-importing countries. Also, banking sector development not only leads directly to economic growth but also can play a moderator role in the oil price—economic growth nexus.

Research limitations/implications

The study has two principal limitations. On the one hand, this study was conducted in a relatively limited sample of countries. On the other hand, the study did not consider others indicators for banking sector development and others macroeconomic variables.

Practical implications

The results found have imperative implications for banks' managers, regulators and researchers. Bank managers should be more concerned with the negative repercussions of oil price fluctuations on the development of their banks. The regulatory authorities must emphasize policies and strategies to further strengthen their banking sector in order to alleviate the negative influence of oil price shocks on economic growth. Researchers focused on finance-growth nexus must take into account the potential influence of oil price shocks.

Originality/value

The developed conceptual model allows examining to what extent the oil price fluctuations might affect the relationship between economic growth and banking sector development. This effect is neither evaluated nor clarified in the relevant literature.
Conflict personalization: a systematic literature review and the development of an integrative definition
Authors: Hoogenboom Lilian M. , Dijkstra Maria T.M. , Beersma Bianca
Published: September 2023

Purpose

Scholars and practitioners alike wish to understand what makes workplace conflict beneficial or injurious to, for example, performance and satisfaction. The authors focus on parties’ personal experience of the conflict, which is complementary to studying conflict issues (i.e. task- or relationship-related conflict). Although many authors discuss the personal experience of conflict, which the authors will refer to as conflict personalization, different definitions are used, leading to conceptual vagueness. Therefore, the purpose of this paper is to develop an integrative definition of the concept of conflict personalization.

Design/methodology/approach

The authors conducted a systematic literature review to collect definitions and conceptualizations from 41 publications. The subsequent thematic analysis revealed four building blocks that were used to develop an integrative definition of conflict personalization.

Findings

The authors developed the following definition: Conflict personalization is the negative affective as well as cognitive reaction to the self being threatened and/or in danger as a result of a social interaction about perceived incompatibilities.

Practical implications

The integrative definition of this study enables the development of a measurement instrument to assess personalization during workplace conflict, paving the way for developing effective research-based interventions.

Originality/value

Conceptual vagueness hampers theoretical development, empirical research and the development of effective interventions. Although the importance of conflict personalization is mentioned within the field of workplace conflict, it has not been empirically studied yet. This paper can serve as the basis for future research in which conflict issue and personal experience are separated.
Sustainability in education through collaborative learning using social media: an exploratory study with moderating role of “knowledge creator” and “knowledge seeker”
Authors: Chaudhuri Ranjan , Chatterjee Sheshadri , Vrontis Demetris , Begalli Diego
Published: September 2023

Purpose

This study aims to examine the impact of social media (SM) on the interactivity among teachers, among students and between students and teachers for sustainable academic performance and for achieving sustainable development (SD) in higher educational institutes. This study also investigates the moderating impact of knowledge creators (KNC) and knowledge seekers (KNS) on the collaborative learning environment using SM.

Design/methodology/approach

With the help of Vroom’s expectancy motivation theory (1964), collaborative learning theory and other theories, a theoretical model has been developed. This theoretical model has been tested using the structural equation modeling technique with 375 participants taken from different educational institutes. The respondent-–participants were both teachers and students.

Findings

The study found that SM plays a significant role in achieving SD al goals and enhances collaborative learning activities among teachers and students to improve academic performance to achieve SD in higher educational institutes. Also, the study highlighted that both “knowledge creators” and “knowledge seekers” have effective moderating impact on the linkage between “intention to use SM for knowledge sharing” and “collaborative learning using social media” to achieve SD al goals.

Research limitations/implications

With the inputs from expectancy-instrumentality-valance theory and collaborative learning theory and existing literature, a theoretical model has been developed conceptually. Later, the model was successfully validated with an overall high explanatory power (72%) of this model. As the sample of the study do not represent a global representation of the population, thus the findings cannot be generalizable.

Practical implications

This study has provided valuable inputs to the SD practitioners and educational policymakers to formulate appropriate policies that enable SD al activities in higher educational institutes. This study also provides food for thought to the policymakers about the role of KNC and KNS toward the collaborative learning environment in achieving SD al goals in higher educational institutes.

Originality/value

The theoretical model developed in this study is unique. This study shows how both “knowledge creator” and “knowledge seeker” play a significant role toward collaborative learning and helps to achieve SD in higher learning institutes and improves their performance. The overall predictive power of the model is 72%, which also shows the effectiveness and uniqueness of the proposed model.
An efficient energy-based methodology for seismic collapse assessment of steel moment frame buildings
Authors: Esmailzadeh-Shahri Reza , Eshghi Sassan
Published: September 2023

Purpose

Nonlinear dynamic analyses are employed for seismic collapse risk evaluation of existing steel moment frame buildings. The standards, such as ASCE 41-17, often define collapse thresholds based on plastic deformations; however, the collapse process involves several factors, and plastic deformation is only one of them. An energy-based approach employs deformation and resistance responses simultaneously, so it can consider various factors such as excessive deformation, stiffness and resistance degradation, and low-cycle fatigue as cumulative damage for seismic assessment. In this paper, an efficient energy-based methodology is proposed to estimate the collapse threshold responses of steel moment frame buildings.

Design/methodology/approach

This methodology uses a new criterion based on the energy balance concept and computes the structural responses for different seismic hazard levels. Meanwhile, a pre-processing phase is introduced to find the records that lead to the collapse of buildings. Furthermore, the proposed methodology can detect failure-prone hinges with a straightforward probability-based definition.

Findings

The findings show that the proposed methodology can estimate reasonably accurate responses against the results of the past experiment on the collapse threshold. Based on past studies, ASCE 41-17 results differ from experimental results and are even overly conservative in some cases. The authors believe that the proposed methodology can improve it. In addition, the failure-prone hinges detected by the proposed methodology are similar to the predicted collapse mechanism of three mid-rise steel moment frame buildings.

Originality/value

In the proposed methodology, new definitions based on energy and probability are employed to find out the structural collapse threshold and failure-prone hinges. Also, comparing the proposed methodology results against the experimental outcomes shows that this methodology efficiently predicts the collapse threshold responses.
Political connections and firms’ trade credit in emerging economies
Authors: Zou Honghui , Xie En , Mei Nan
Published: September 2023

Purpose

Trade credit is an important business-to-business marketing tool for building firms’ competitive advantage. Many studies explore the determinants of trade credits from a trust-based view, but the role of political connections is largely overlooked, despite their potential influence in assessing firms’ trustworthiness in the context of emerging economies. This study aims to fill this gap by examining how political connections affect the capacity of emerging economy firms (EEFs) to grant and receive trade credit.

Design/methodology/approach

This study tests a conceptual model using secondary data collected from 1,149 Chinese privately owned listed manufacturing firms between 2008 and 2016.

Findings

This study finds that political connections reduce EEFs’ accounts receivable and payable; their philanthropic activities alleviate this negative effect for accounts payable, while patent applications reduce it for accounts receivable. These findings suggest the effect of political connections can spillover to EEFs’ relationship with their up- and down-stream partners.

Practical implications

This study has implications EEF managers, particularly in pointing to the detrimental effect of political connections on relationships with buyers and suppliers, and highlights the need to adopt suitable approaches to offset this effect.

Originality/value

This study sheds new light on the negative effect of political connections on EEFs’ capacity to grant and receive trade credit in their exchanges with up-stream and down-stream partners. It enriches the trust-based view of trade credit by revealing the significant influence of EEFs’ political connections, while also advancing a contingency view by testing the moderating role of corporate philanthropic activities and patent applications.

Authors: Lamph Gary , Elliott Alison , Wheatcroft Sue , Rayner Gillian , Gardner Kathryn , Haslam Michael , Jones Emma , McKeown Mick , Gibbon Jane , Graham-Kevan Nicola , Wright Karen
Published: September 2023

Purpose

The aim of this paper is to provide an overview of a novel offender personality disorder (OPD) higher education programme and the research evaluation results collected over a three-year period. Data from Phase 1 was collected from a face-to-face mode of delivery, and Phase 2 data collected from the same programme was from an online mode of delivery because of the COVID-19 pandemic.

Design/methodology/approach

In Phase 1, three modules were developed and delivered in a fully face-to-face format before the pandemic in 2019–2020 (n = 52 student participants). In 2020–2021 (n = 66 student participants), training was adapted into a fully online mode of delivery in Phase 2. This mixed-methods study evaluated participant confidence and compassion. Pre-, post- and six-month follow-up questionnaires were completed. Qualitative interviews were conducted across both phases to gain in-depth feedback on this programme (Phase 1: N = 7 students, Phase 2: N = 2 students, N = 5 leaders). Data from Phase 1 (face-to-face) and Phase 2 (online) are synthesised for comparison.

Findings

In Phase 1 (N = 52), confidence in working with people with personality disorder or associated difficulties improved significantly, while compassion did not change. In Phase 2 (N = 66), these results were replicated, with statistically significant improvements in confidence reported. Compassion, however, was reduced in Phase 2 at the six-month follow-up. Results have been integrated and have assisted in shaping the future of modules to meet the learning needs of students.

Research limitations/implications

Further research into the impact of different modes of delivery is important for the future of education in a post-pandemic digitalised society. Comparisons of blended learning approaches were not covered but would be beneficial to explore and evaluate in the future.

Practical implications

This comparison provided informed learning for consideration in the development of non-related educational programmes and, hence, was of use to other educational providers.

Originality/value

This paper provides a comparison of a student-evaluated training programme, thus providing insights into the impact of delivering a relational-focused training programme in both face-to-face and online distance learning delivery modes. From this pedagogic research evaluation, the authors were able to derive unique insights into the outcomes of this programme.

Authors: Tawse Alex , Atwater Leanne , Vera Dusya , Werner Steve
Published: September 2023

Purpose

Strategy implementation is a critical component of firm performance and middle managers play a key role in the implementation process. This study was conducted to enhance the authors’ understanding of how middle managers influence strategy implementation (SI) effectiveness by investigating the impact of leadership and work team coordination.

Design/methodology/approach

A field study was conducted using interviews and survey data gathered from executive managers, middle managers and work team members within a large municipal organization undergoing a major strategic change.

Findings

Middle manager transformational and instrumental leadership have a direct positive impact on work team SI effectiveness. Additionally, middle manager transformational leadership has an indirect positive effect on work team SI effectiveness through coordination.

Practical implications

The study offers insights into managers and practitioners seeking to improve SI effectiveness by highlighting the importance of middle manager leadership development and the coordination of interdependent tasks within work teams.

Originality/value

The study provides valuable insight into an important but previously unstudied relationship between middle manager leadership and SI effectiveness. The work also helps bridge the chasm between leadership research and strategy research by linking leadership behavior to SI effectiveness – a key ingredient of firm performance.
Nurse leaders’ perceptions of future leadership in hospital settings in the post-pandemic era: a qualitative descriptive study
Authors: Vuorivirta-Vuoti Eeva , Kuha Suvi , Kanste Outi
Published: September 2023

Purpose

Coronavirus disease (COVID-19) has challenged leadership in hospitals worldwide. The experiences of leadership during the pandemic changed leadership significantly. This study aims to describe nurse leaders’ perceptions of what future leadership in hospital settings in the post-pandemic era needs to be like.

Design/methodology/approach

A qualitative descriptive study was used. A total of 20 nurse leaders from the Finnish central hospital were interviewed from June to October 2021. The data were analysed using inductive content analysis.

Findings

The analysis revealed five main categories describing nurse leaders’ perceptions of future leadership in hospital settings in the post-pandemic era: digitalisation and hybrid working culture, development of sustainable working conditions, moving smoothly to the post-pandemic era, dissolution of traditional regimes of organisation and flexibility in leadership.

Practical implications

In the post-pandemic era, the constantly changing demands and challenges currently facing healthcare systems have significantly increased the complexity of hospital organisations. This requires critical evaluation and change to traditional leadership. Enhancing flexibility and authenticity in leadership, strengthening competencies, implementing a wide range of digital resources and increasing the appeal of the nursing profession to build the next generation of nurses – all of these are needed to provide sustainability in future healthcare.

Originality/value

The results identify the critical points of leadership that need to be developed for future challenges and for maintaining a sufficient supply of qualified professionals. Acting on this information will enhance flexibility in organisations and lead to acceleration of changes and the development of new kinds of leadership in the future
Preparation of alcohol-resistant ink using polyester resin for thermal transfer ribbon
Authors: Yang Yuanhao , Chen Guangyu , Luo Zhuo , Huang Liuqing , Zhang Chentong , Luo Xuetao , Luo Haixiang , Yu Weiwei
Published: September 2023

Purpose

The purpose of this study is to prepare thermal transfer ribbons with good alcohol resistance.

Design/methodology/approach

A variety of alcohol-resistant thermal transfer inks were prepared using different polyester resins. The printing temperature, printing effect, adhesion and alcohol resistance of the inks on the label were studied to determine the feasibility of using the ink for manufacturing thermal transfer ribbons. The ink formulations were prepared by a simple and stable grinding technology, and then use mature coating technology to make the ink into a thermal transfer ribbon.

Findings

The results show that the thermal transfer ink has good scratch resistance, good alcohol resistance and low printing temperature when the three resins coexist. Notably, the performance of the ribbon produced by 500 mesh anilox roller was better than that of other meshes. Specifically, the ink on the matte silver polyethylene terephthalate (PET) label surface was wiped with a cotton cloth soaked in isopropyl alcohol under 500 g of pressure. After 50 wiping cycles, the ink remained intact.

Originality/value

The proposed method not only ensures good alcohol resistance but also has lower printing temperature and wider label applicability. Therefore, it can effectively reduce the loss of printhead and reduce production costs, because of the low printing temperature.
Controlling anisotropy and brittle-to-ductile transitions by varying extrusion width in short fibre reinforced additive manufacturing
Authors: Yan Jiongyi , Demirci Emrah , Gleadall Andrew
Published: September 2023

Purpose

Extrusion width, the width of printed filaments, affects multiple critical aspects in mechanical properties in material extrusion additive manufacturing: filament geometry, interlayer load-bearing bonded area and fibre orientation for fibre-reinforced composites. However, this study aims to understand the effects of extrusion width on 3D printed composites, which has never been studied systematically.

Design/methodology/approach

Four polymers with and without short-fibre reinforcement were 3D printed into single-filament-wide specimens. Tensile properties, mechanical anisotropy and fracture mechanisms were evaluated along the direction of extruded filaments (F) and normal to the interlayer bond (Z). Extrusion width, nozzle temperature and layer height were studied separately via single-variable control. The extrusion width was controlled by adjusting polymer flow in the manufacturing procedure (gcode), where optimisation can be achieved with software/structure design as opposed to hardware.

Findings

Increasing extrusion width caused a transition from brittle to ductile fracture, and greatly reduced directional anisotropy for strength and ductility. For all short fibre composites, increasing width led to an increase in strain-at-break and decreased strength and stiffness in the F direction. In the Z direction, increasing width led to increased strength and strain-at-break, and stiffness decreased for less ductile materials but increased for more ductile materials.

Originality/value

The transformable fracture reveals the important role of extrusion width in processing-structure-property correlation. This study reveals a new direction for future research and industrial practice in controlling anisotropy in additive manufacturing. Increasing extrusion width may be the simplest way to reduce anisotropy while improving printing time and quality in additive manufacturing.
An assessment of crime prevention through environmental design in student housing: a weight-of-evidence approach
Authors: Attakora-Amaniampong Elvis
Published: September 2023

Purpose

There is a robust study on crime prevention through environmental design (CPTED) in student housing nowadays, but has a limited utilization of weight-of-evidence (W-o-E) approach. This study aims to assess the extent of CPTED in student housing facilities of universities in Ghana.

Design/methodology/approach

Using the on-campus student housing facilities of both private and public universities, the study adopted W-o-E approach that integrates two postoccupancy evaluations from end-users and student housing managers. In addition, observation by professionals as the lines of evidence (LoE) was also adopted. Weighted median was used to normalise the LoE into a W-o-E as the CPTED value in the student housing facilities.

Findings

The study uncovered low CPTED in the student housing facilities. Maintenance was identified as the leading CPTED principle present in the student housing facilities.

Practical implications

The study has given the extent of CPTED in students’ housing, an important insight for university students’ housing management. This can serve as a policy alert for the university students’ housing management to adopt building designs that enhance CPTED and the safety of the youth.

Originality/value

This study is different from other CPTED and students’ housing studies commonly situated in the Euro-America context. The study exceptionally applied the use of W-o-E in students’ housing in assessing the extent of CPTED in student housing within the context of sub-Saharan African universities.
An evaluation of a violence reduction partnership network: mixed methods network analysis
Authors: Wilkinson Dean , Thompson Alison , Kerslake Debbie , Chopra Isha , Badger Sophie
Published: September 2023

Purpose

The purpose of this paper was to report on the evaluation of the network and resources for violence prevention and reduction in the chosen area of focus. This area had experiences deprivation, significant implications due to Covid-19 restrictions and a lack of outdoor recreation space.

Design/methodology/approach

Network analysis methodologies are increasingly being used in criminological research and evaluations to assess the structures of social and economic networks. This study explored, using a mixed-methods network analysis methodology, the nature of the established violence reduction network in a specific geographical location in West Midlands.

Findings

A breadth of network activity is taking place across the community; however, the network analysis highlighted gaps in terms of specialist provision for early years and support from those with lived experience. It was perceived that a lack of continuity, in terms of changes in key roles, has affected the network. Funding mechanisms were perceived ineffective, and not encouraging of development of localisation services. Relationships between network members were predominantly positive with organisations having good communication and accessing support from one another; however, identifying shared goals and better collective working would benefit the network.

Originality/value

This study pioneers using an innovative, mixed methods network analysis to explore a public health approach to violence prevention and reduction. Quantitative data collection and analysis allowed for assessment of the networks capacity and density, whereas qualitative data provided insights and detailed accounts of how the network functions.

Purpose

The main aim of this study is to review different aspects of Industry 5.0 (I5.0) along with Kaizen measures to foster this novel aspect of industrial sustainability. The study makes a comprehensive study to explore the implementation status of I5.0 in industries, key technologies, adoption level in different nations and barriers to I5.0 adoption together with mitigation actions.

Design/methodology/approach

To do a systematic study of the literature, the authors have used preferred reporting items for systematic reviews and meta-analysis (PRISMA) methodology to extract articles related to the field of the study.

Findings

It has been found that academic literature on the I5.0 is continuously growing as the wheel of time is running. Most of the studies on I5.0 are conceptual-based, and manufacturing and medical industries are the flag bearer in the adoption of this novel aspect. Further, due to I5.0's infancy, many organizations face difficulty to adopt the same due to financial burden, resistive nature, a well-designed standard for cyber-physical systems (CPS) and an effective mechanism for human–robot collaboration. Further studies also provide avenues for future research in terms of the identification of collaborative mechanisms between machines and wells, the establishment of different standards for comparison and the development of I5.0-enabled models for different industrial domains.

Originality/value

The study is the first of its kind that reviews different facets of I5.0in conjunction with Kaizen's measures and application areas and provides avenues for future research to improve an organization's environmental and social sustainability.

Polysaccharides are promising biomolecules with lowtoxicity and diverse bioactivities in food processing and clinical drug development. However, an essential prerequisite for their applications is the fine structure characterization. Due to the complexity of polysaccharide structure, partial degradation is a powerful tool for fine structure analysis, which can effectively provide valid information on the structure of backbone and branching glycosidic fragments of complex polysaccharides. This review aims to conclude current methods of partial degradation employed for polysaccharide structural characterization, discuss the molecular mechanisms, and describe the molecular structure and solution properties of degraded polysaccharides. In addition, the effects of polysaccharide degradation on the conformational relationships between the molecular structure and bioactivities, such as antioxidant, antitumor, and immunomodulatory activities, are also discussed. Finally, we summarize the prospects and current challenges for the partial degradation of polysaccharides. This review will be of great value for the scientific elucidation of polysaccharide fine structures and potential applications.

Fritillaria cirrhosa D. Don, which can be used for medicine and food, contains a variety of chemicals including polyphenols, alkaloids, terpenoid, and others that have beneficial biological properties like antihypertension, bacteriostasis, and anti‐inflammatory. The ethanolic extract of Fritillaria straw was obtained for this study using ultrasonic‐aided extraction, and the amounts of total phenols and total flavonoids were 26.56 ± 1.36 mg GAE/g dw and 18.75 ± 0.80 mg RE/g dw, respectively. Ultra‐performance liquid chromatography–quadrupole time‐of‐flight–mass spectrometry technology was utilized to identify 50 major chemicals in the Fritillaria straw extract (FSE). Meanwhile, the antioxidative activities of FSE were evaluated by 2,2‐diphenyl‐1‐picrylhydrazyl, 2,2′‐azino‐bis(3‐ethylbenzothiazoline‐6‐sulfonic acid) and Ferric reducing antioxidant power assays in vitro, which pointed out the antioxidative potential of FSE. Additionally, 0.1%, 0.5%, and 1% of FSE and 0.02% butylated hydroxyanisole (BHA) + butylated hydroxytoluene (BHT) (1:1) were separately added to Chinese‐style sausage to study their effects on the lipid oxidation, protein oxidation, and quality of the sausage at different storage times. The study found that the effect of adding 1% FSE on carbonyl content, total volatile basic nitrogen, and TVC of sausage could achieve the effect of the 0.02% BHA + BHT (1:1) group on the 35th day, and the thiobarbituric acid reactive substances value and peroxide value of sausage were significantly lower than the control group. Therefore, as one of the candidates to replace synthetic antioxidants, the FSE can be used in the production of Chinese sausages, which has a positive effect on improving the product's quality and extending the shelf life.

Practical Application

The antioxidative activities of 50 main compounds were identified after the ethanolic extraction of Fritillaria straw. This Fritillaria straw extract was added to Chinese sausage, effectively inhibiting the oxidation of lipids and proteins as well as the decomposition of proteins. Obviously, the Fritillaria straw extract, one of the choices to replace synthetic antioxidants, may be useful for future meat processing, because of its positive impact on the product's quality and shelf life.
Ex‐military Top Executives and Corporate Violations: Evidence from China
Authors: Zhang Dunli , Zhou Jinzhao , Ma Jingjuan
Published: September 2023

We examine the association between corporate violations and executives who formerly served in the military, using a sample of A‐share listed firms in China from 2004 to 2018. We find that firms led by ex‐military executives are less likely to incur corporate violations. Further tests indicate that where there is a negative relationship this association is more pronounced for non‐financial corporate violations than for cases involving financial fraud. We also confirm that the association between corporate misconduct and firms with ex‐military executives is more significant if the firm has insufficient external oversight. The results are robust to a series of robustness tests. Overall, our results suggest that executives’ exposure to military culture has a governance effect in regulating corporate behaviour and outcomes in emerging economies.
