Artificial first-order phase transition in a magnetized Nambu–Jona-Lasinio model with a quark anomalous magnetic moment
Authors: Tavares William R. , Avancini Sidney S. , Farias Ricardo L. S. , Cardoso Rafael P. 
Published: January 2024

Recently, first-order phase transitions have been predicted as an effect of the inclusion of quark anomalous magnetic moment (AMM) in the hot and magnetized Nambu–Jona-Lasinio model (NJL). These transitions appear in the chiral condensate for different combinations of AMM and magnetic fields and could lead to inverse magnetic catalysis. However, in this work, we show that the predicted first-order phase transitions are related to regularization-dependent issues. To show this, we explore, in the context of the vacuum magnetic regularization (VMR) scheme, two different scenarios: when mass-dependent (MD) and mass-independent (MI) terms are present in the subtraction of the divergences. In the MD case, as we increase the AMM value, it is observed the appearance of a nonmassive minimum in the thermodynamical potential, which induces a first-order phase transition from the massive minimum. We argue that the MD terms must be avoided in order to satisfy the predictions of Lattice QCD, and we propose a MI solution that is valid in the limit which the magnetic fields are smaller than the squared of vacuum effective quark mass.

Authors: Li Zhaozhi , Zhang Changfu , Zhang Hairong , Liu Haihui , Zhu Zhao , Wang Liucheng 
Published: January 2024

Purpose
This study aims to apply an electrochemical grinding (ECG) technology to improve the material removal rate (MRR) under the premise of certain surface roughness in machining U71Mn alloy.

Design/methodology/approach
The effects of machining parameters (electrolyte type, grinding wheel granularity, applied voltage, grinding wheel speed and machining time) on the MRR and surface roughness are investigated with experiments.

Findings
The experiment results show that an electroplated diamond grinding wheel of 46# and 15 Wt.% NaNO3 + 10 Wt.% NaCl electrolyte is more suitable to be applied in U71Mn ECG. And the MRR and surface roughness are affected by machining parameters such as applied voltage, grinding wheel speed and machining time. In addition, the maximum MRR of 0.194 g/min is obtained with the 15 Wt.% NaCl electrolyte, 17 V applied voltage, 1,500 rpm grinding wheel speed and 60 s machining time. The minimum surface roughness of Ra 0.312 µm is obtained by the 15 Wt.% NaNO3 + 10 Wt.% NaCl electrolyte, 13 V applied voltage, 2,000 rpm grinding wheel speed and 60 s machining time.

Originality/value
Under the electrolyte scouring effect, the products and the heat generated in the machining can be better discharged. ECG has the potential to improve MRR and reduce surface roughness in machining U71Mn.

Authors: Veríssimo Larissa , Rainey Helen , Lindemann Roberta , Hendry Anne 
Published: January 2024

Purpose This viewpoint piece will highlight the contribution of trained lay community health workers to the integrated workforce in rural, remote and island settings, drawing on experience from a system strengthening project involving community health agents (CHAs) in four municipalities in Litoral Norte, a remote coastal and island region in the state of São Paulo, Brazil.Design/methodology/approach This viewpoint reflects on experiential learning from a unique north–south collaboration that spanned the period of a global pandemic. It adds to the international literature on the value of community health workers in public health and chronic disease management and highlights their potential pivotal role as integrators at point of care.Findings CHAs took forward actions that touched the lives of thousands of vulnerable families with low income and complex needs in communities with high levels of social and health inequalities. They acted as a bridge between patients and families at home, primary healthcare professionals and wider community partners and services. Their valuable insight into the healthcare issues and social challenges experienced by the community informed and supported family centred practice and population health goals. The CHAs rapidly pivoted to became an essential public health workforce during the Covid-19 pandemic.Practical implications As the authors establish integrated care systems and embrace proactive care and population health, the conditions are favourable for introducing a similar role in the UK. For psychological safety and avoidance of burnout people in such new roles will require training, supervision and full integration within community teams.Originality/value This viewpoint reflects experiential learning from a unique north–south collaboration that spanned the period of a global pandemic.

The role of gender-identity congruity in cross-gender endorsement in the context of live streaming
Authors: Chen Xiang , Guo Shuojia , Han Shuhua 
Published: January 2024

PurposeThis paper critically examines the effectiveness of male anchor in cross-gender endorsements and questions whether it can truly deliver positive outcomes for advertisers in the context of live streaming. It explores the underlying mechanisms of this effect by examining the mediation effect of perceived gender-identity incongruence and the moderation effect of anchor presence.Design/methodology/approachThree experiments are conducted to examine the effect of cross-gender endorsement on purchase intention.FindingsThe findings from three experiments provide empirical evidence that the endorsement of female-gendered products by male anchors leads to a significant decrease in the evaluation of these products among female consumers. This negative effect is mediated by a sense of gender-identity incongruence experienced by female consumers. Furthermore, the study demonstrates that female customers exhibit higher purchase intent for female-gendered products endorsed by male virtual anchors compared to real anchors; however, the same pattern was not observed in the case of female anchors.Originality/valueThis paper empirically examines the possible negative effects of the male anchor endorsement in the live streaming context. It reveals the underlying mechanism of this negative effect, and how the virtual “presence” take a role in this underlying mechanism.
From pixels to engagement: examining the impact of image resolution in cause-related marketing on Instagram
Authors: Ryu Sann 
Published: January 2024

PurposeThis study aims to examine the visual effects of cause-related marketing (CM) posts on Instagram, with a focus on image resolution and consumer engagement.Design/methodology/approachThree studies were conducted through an experimental design. Study 1 (N = 155) uncovered the mediation underlying the effects of image quality (low and high image resolution). Study 2 (N = 160) replicated the findings of the first study and extended the investigation by examining the mediator (fluency) and moderator (visual sensitivity). Study 3 (N = 291) further extended the effects of image resolution by demonstrating its interactive effects with the visual complexity of an Instagram post design in a 2 × 2 factorial experiment.FindingsThe serial mediation analysis demonstrated that high image resolution CM posts yielded more favorable evaluations in terms of brand credibility and information costs saved, subsequently leading to positive brand attitudes, purchase intentions and increased Instagram engagement. Processing fluency mediated image effects on brand credibility, while individual differences in visual sensitivity moderated the image effects. The image resolution effects were greater for visually complex CM posts compared to simple ones.Originality/valueTo one's best knowledge, little to no research has examined the image quality of Instagram posts in the context of CM and the extent to which such visual cues can affect consumers' brand evaluations and engagement on the platform.Research implicationsDespite its practical significance, there exists a notable gap in understanding the specific role of CM posts on Instagram and the impact of visual elements on consumer behaviors. The current research findings aim to bridge the research gap.
Employee cohesion and its influence on workplace learning: The lived experiences of public university lecturers in Ethiopia
Authors: Birhanu Ermiyas Tsehay , Gugssa Mulugeta Awayehu 
Published: January 2024

Purpose
The purpose of this study is to investigate the driving factors for staff cohesiveness in the workplace and how they are related to workplace learning and development opportunities. Two research questions guided the inquiry: (1) What are the driving factors for staff cohesiveness in the workplace? and (2) How does staff cohesiveness influence workplace learning?

Design/methodology/approach
This study is based on a phenomenological research design. The data collection involved interviews and focus group discussions with 22 lecturers in two public universities. Thematic analysis was followed to analyse and interpret data.

Findings
The findings of this study indicate that staff cohesiveness is greatly influenced by several factors. Firstly, the presence of shared visions and goals plays a significant role in fostering staff cohesion. In addition, the similarity of age and gender among employees, as well as the presence of mutual support and a sense of belongingness, trust and solidarity, managerial support and the nature of the job that requires collective action, all contribute to staff cohesiveness. It is worth noting that previous studies have not reported the influence of age, gender and job characteristics as factors influencing staff cohesiveness.

Practical implications
Employers should not only focus on the knowledge and hard skills of applicants but also on the soft skills which support teamwork and cohesion in the workplace. Managers who want to enhance workplace learning should create opportunities for social gatherings and informal contacts in the workplace to facilitate informal learning in the workplace. Researchers focusing on workplace learning should include tacit learning practices that occur in the workplace as a result of the closeness between teammates.

Originality/value
This manuscript, which the authors hereby present, is the result of own original work. To the best of the authors’ knowledge, the authors wish to emphasise that it has not been submitted for publication in any other journals.
The mediating role of capital on deposit insurance and financial stability: evidence from Islamic and conventional banks
Authors: Ben-Ammar Houssem 
Published: January 2024

PurposeThis study aims to evaluate the interaction between bank capital and explicit deposit insurance scheme (DIS) on the financial stability of Islamic and conventional banks.Design/methodology/approachThe author's sample covers 52 Islamic and 108 conventional banks operating in 12 countries over the period 2000–2021 using the random-effects generalized least squares (RE-GLS) regression technique.FindingsThe author's results reveal that bank capital negatively mediates the relationship between explicit DIS and the financial stability of both Islamic and conventional banks. Additionally, explicit DIS has a positive impact on the financial stability of conventional banks. However, the results are mixed for Islamic banks, as the effect of explicit DIS is positive for the Middle East and North Africa (MENA) region but negative for the South and Southeast Asia (SSA) region. Finally, the interaction between explicit DIS and the COVID-19 pandemic has a negative effect on conventional banks operating in the MENA region, while it has a positive effect on Islamic banks operating in the SSA region.Research limitations/implicationsThe findings of this paper have important implications for regulators in evaluating DIS policies and in anticipating any potential adverse consequences that might arise for both Islamic and conventional banks in normal and crisis times. Policymakers should strive to preserve the benefits of DIS while mitigating the destabilizing effects of its interaction with capital ratios.Originality/valueThis study introduces a novel aspect by examining the mediating role of capital in the relationship between explicit DIS and the financial stability of Islamic and conventional banks.
Transforming practices of co-creating values in a contemporary art exhibition
Authors: Kłeczek Ryszard , Hajdas Monika 
Published: January 2024

Purpose
This study aims to investigate how art events can enrich novice visitors by transforming their practices.

Design/methodology/approach
This research uses an interpretive case study of the art exhibition “1/1/1/1/1” in the Oppenheim gallery in Wroclaw. It draws on multiple sources of evidence, namely, novice visitors’ interviews, observation including photo studies and content analysis of art-makers’ mediation sources. This study is an example of contextual theorizing from case studies and participatory action research with researchers as change agents.

Findings
The evidence highlights that aesthetic values and experiences are contextual to practices and are transformable into other values. The findings illustrate the role of practice theory in studying how art-makers inspire the transformation of practices, including values driving the latter.

Research limitations/implications
The findings provide implications for transformations of co-creating contextual values in contemporary visual art consumption and customer experience management.

Practical implications
Practical implications to arts organizations are also provided regarding cultural mediation conducted by art-makers. Exhibition makers should explain the meanings of the particularly visible artefacts to allow visitors to develop a congruent understanding of the meanings. The explanations should not provide ready answers or solutions to the problem art-makers suggest to rethink.

Social implications
The social implication of our findings is that stakeholders in artistic ventures may undertake adequate, qualified and convergent actions to maintain or transform the defined interactive practices between them in co-creating contextual aesthetic values.

Originality/value
The study provides new insights into co-creating values in practices in the domain of contemporary art exhibitions by bringing the practice theory together with an audience enrichment category, thus illustrating how novice visitors get enriched by transforming their practices led by contextual values of “liking” and “understanding”.

Authors: Gheorghe Andreea , Curșeu Petru Lucian , Fodor Oana C. 
Published: January 2024

Purpose
This study aims to explore the role of team personality and leader’s humor style on the use of humor in group communication and the extent to which group humor mediates the association between team personality on the one hand, psychological safety, collective emotional intelligence and group satisfaction on the other hand.

Design/methodology/approach
The authors used a survey to collect data from 304 employees nested in 83 groups working in organizations from various sectors in Romania.

Findings
The study results show that extraversion is positively associated with group affiliative humor, while neuroticism has a positive association with group aggressive humor. The leader’s affiliative humor style had a significant positive effect on group affiliative humor, while the effect of leader’s aggressive humor style on the use of aggressive humor in groups was not significant. Furthermore, the authors examined the mediation role of group humor in the relationship between team personality and team emergent states and satisfaction. The authors found that group aggressive humor mediates the association between neuroticism and group emotional intelligence, psychological safety and satisfaction, while affiliative humor mediates the association between extraversion and emotional intelligence and team satisfaction.

Originality/value
The study reports one of the first attempts to explore the multilevel interplay of team personality and humor in groups as they relate to emergent states.
Apocynin exerts neuroprotective effects in fumonisin b1–induced neurotoxicity via attenuation of oxidative stress and apoptosis in an animal model

Published: January 2024

AbstractThe Fusarium verticillioides produces a mycotoxin, that is, fumonisin b1 (Fb1), which commonly infects corn and agricultural commodities. The Fb1 showed hepatotoxicity, neurotoxicity, and carcinogenicity in animals. Hence, the present investigation aimed to evaluate the effect of apocynin (AP) on Fb1‐induced neurotoxic effects and its mechanism in the mice model and cell line. The male Balb/c mice, with the 6.75 mg/kg bwt of Fb1 were injected subcutaneously for 5 days to induce neurotoxicity. A significant elevation of serotonin (5‐HT) was observed in mice treated with Fb1 in the whole brain showing biogenic amines may reflect Fb1 neurotoxicity, but the negatively regulated mechanisms were attenuated by the pretreatment of AP. In addition, AP pretreatment normalized apoptotic changes in histology and immunohistochemistry studies. In Western blotting studies, apoptotic genes were upregulated and oxidative stress genes were downregulated due to Fb1 treatment; while treating with AP, these gene expressions were rectified. Further cell cytotoxicity was investigated by MTT and lactate dehydrogenase (LDH) assays in SH‐SY5Y cell line. MTT and LDH assays indicated the IC50 value to be 150 µM of Fb1, which was protected by 100 µg of AP. The electron microscopy evaluated the Fb1‐induced apoptotic conditions and its cell morphology recovery by AP. These results suggest that nicotinamide adenine dinucleotide phosphate hydrogen oxidase–mediated reactive oxygen species is the primary upstream signal leading to increased Fb1‐mediated neurotoxicity in mice. The use of the antioxidant AP reversed the toxin‐induced oxidative stress and apoptosis by its antioxidant potency.
