Published: November 2024

Two Gram-stain-negative bacterial strains, BSw22131T and DMSP-1T, were isolated from seawater of Arctic Kongsfjorden in the Ny-Ålesund area, Svalbard. Strains BSw22131T and DMSP-1T were within the genus Pseudomonas and presented 98.1 and 99.8% 16S rRNA gene sequence similarity to Pseudomonas piscicola P50T and Pseudomonas paracarnis V5/DAB/2/5T, respectively. However, the results of multilocus sequence analysis (concatenated 16S rRNA, gyrB, rpoB and rpoD gene sequences) and whole-genome sequence analysis indicated that BSw22131T and DMSP-1T were most closely related to Pseudomonas petrae P2653T and Pseudomonas lactis DSM 29167T, respectively. The genome G+C contents of strains BSw22131T and DMSP-1T were 58.2 and 60.0%, respectively. The two isolates presented digital DNA–DNA hybridization and average nucleotide identity values of less than 70 and 96%, respectively, with type strain genomes of their close relatives. BSw22131T contained summed feature 3 (C16 : 1
ω6c/C16 : 1
ω7c), C16 : 0 and summed feature 8 (C18 : 1
ω6c/C18 : 1
ω7c) as the major cellular fatty acids, whereas DMSP-1T contained an additional C17 : 0-cyclo as the major fatty acid. The major quinones of both strains were Q-9 (57.5–77.2%) and Q-8 (22.8–37.2%), and their major cellular polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. BSw22131T could be differentiated from its related species by positive ornithine decarboxylase, esterase (C8) and l-rhamnose and d-fructose-6-PO4 utilization, whereas DMSP-1T could be differentiated by positive acid phosphatase but negative p-hydroxyphenylacetic acid utilization. The two strains were negative for the reduction of nitrates but contained genes related to dimethylsulfoniopropionate catabolism. The results of the polyphasic taxonomy analysis revealed that strains BSw22131T and DMSP-1T represent two novel species of the genus Pseudomonas, for which the names Pseudomonas huanghezhanensis sp. nov. (type strain BSw22131T = CCTCC AB 2019135T = JCM 36635T = DSM 117336T) and Pseudomonas fjordensis sp. nov. (type strain DMSP-1T = CCTCC AB 2019124T = JCM 36636T = DSM 117337T) are proposed.

rocksalt-wurtzite interfaces
Authors: Mahatara Sharad , Lany Stephan 
Published: November 2024

Epitaxial lattice matching is an important condition for the formation of coherent interfaces with low defect densities. However, lattice-matched substrates with the same crystal structure as the active layer are often not available, suggesting opportunities for utilizing heterostructural interfaces. For example, at high Al contents that are interesting for ultrawide-gap applications in power electronics, AlxGa1−xN semiconductor alloys in the (0001) orientation of the wurtzite (wz) structure become lattice-matched to (111)-oriented rocksalt (rs) TaC substrates. To predict the expected interface atomic structures under different synthesis conditions, we perform high-throughput density-functional-theory calculations, using an algorithm for systematic sampling of the possible stacking sequences of the atomic layers on the in-plane hexagonal lattice. The approach considers octahedral, tetrahedral, and prismatic coordination motifs, and is generally applicable for the modeling of commensurate rs/wz heterostructural interfaces. Our results provide guidance for synthesis control of substrate-film bonding and the polarity of ultrawide-gap AlxGa1−xN alloys on TaC substrates.

The complexity of integrating global englishes (GE) in ELT: a case study of an English teacher’s investment and identity construction
Authors: Guo Lisha 
Published: November 2024

Purpose
Although there is growing critical awareness in ELT around the rise of English as a global language, studies on teachers’ investment in critical pedagogy remain limited in mainstream ELT curricula, and the impact of such investment on teachers’ identities is not clear. To address this gap, with the inclusive paradigm of Global Englishes (GE), the paper presents a case study of an English teacher’s investment in GE at a middle school in China.

Design/methodology/approach
This study employed a qualitative approach. Semi-structured interview was conducted with the participant – May, focusing on her reported practices and her understanding of her roles during the investment in GE. The interview process was guided by an interview protocol which was designed based on related literature on GE, the theoretical framework, and the research context. A content analysis method was utilized to generate descriptive categories concerning participant’s identities and investment in GE.

Findings
Analysis of interview data reveals that through investment in GE, May not only constructed her identity as an English teacher, but also explored identities as a student inspirer, and a peer mentor. These identities exploration and construction were primarily driven by her increased cultural and social capital, despite facing challenges such as high-stakes test policies, native-speakerism ideology, institutional requirements, and limited resources.

Research limitations/implications
Future research incorporating triangulating data such as interviews, and classroom observations, would provide a more comprehensive understanding of English teachers’ identities, and investment in GE. Besides, the findings of this study are primarily from one teacher, they may not fully represent the broader population of English teachers in China.

Practical implications
The findings have several implications for English teaching and teacher education. First, elementary schools, the lower grades of middle schools (grades 7 and 8), or the after-school programs may have opportunities for teachers to integrate GE in teaching. Second, teacher education programs should be designed to provide more chances that enable student teachers to invest in their learning and teaching of GE. Third, proposals for incorporating GE practices in the classroom must adopt a critical perspective, so as to to expose, deconstruct, and reconstruct power dynamics that influence teachers’ investment in GE.

Originality/value
The originality of this study lies in its exploration of English teachers’ investment of GE in their teaching, and the impact of this investment on their identities as English teachers. By investigating these aspects, the study addresses the research gaps in English teachers’ practice of integration of GE in mainstream ELT curricula and provides insights on how to encourage English teachers to incorporate a GE-aware perspective in their teaching.
Wage and fiscal policy re-examined. An assessment of employment and productivity using Italian regional data
Authors: Deleidi Matteo , Romaniello Davide , Salvati Luigi , Tosi Francesca 
Published: November 2024

PurposeTraditional economic policy prescriptions proposed to address the Italian North-South divide mainly suggest that, in order to reduce unemployment and stimulate productivity, downwards wage flexibility should be guaranteed and the wage-setting model decentralised to sub-national labour markets. Contrarily, the Keynesian view suggests that higher wages and demand stimuli can engender positive effects on productivity and employment.Design/methodology/approachApplying panel structural VAR modelling to Italian regional data (1995–2019), we evaluate how wages and government expenditure impact productivity and employment dynamics.FindingsWe find that a rise in both government spending and real wages has long-lasting, positive effects on productivity and employment, even when considering centre-northern and southern regions separately.Originality/valueTo the best of our knowledge, this research provides new insights, particularly in the Italian context, by explicitly examining the effects of wage and fiscal policies on two significant macroeconomic variables—employment and productivity—using a novel and integrated approach. Additionally, our findings suggest that conventional policy recommendations warrant reconsideration.
Navigating through geopolitical risk: the role of supply chain concentration
Authors: Zhu Minghao , Miao Shucheng , Lam Hugo K.S. , Liang Chen , Yeung Andy C.L. 
Published: November 2024

PurposeThis study aims to investigate the impact of geopolitical risk (GPR) on supply chain concentration (SCC) and the roles of operational capabilities and resources in this relationship.Design/methodology/approachSecondary longitudinal data from multiple sources is collected and combined to test for a direct impact of GPR on SCC. We further examine the moderating effects of firms’ operational capabilities and resources (i.e. firm resilience, operational slack and cash holding). Fixed-effect regression models are applied to test the hypotheses, followed by a series of robustness tests to check the consistency of the results.FindingsConsistent with the tenets of resource dependence theory, our analysis reveals a significant negative impact of GPR on SCC. Moreover, we find that this adverse effect is attenuated for firms with higher levels of resilience, more operational slack and greater cash holdings. Further analysis suggests that maintaining a diversified supply chain base during heightened GPR is associated with a firm’s improved financial performance.Originality/valueThis study contributes to the supply chain management (SCM) literature by integrating GPR into the supply chain risk management framework. Additionally, it demonstrates the roles of diversification and operational resources in addressing GPR-induced challenges.
Strategic approaches for pharmaceutical distributors to create brand equity in the unorganized pharma retail industry in emerging economies
Authors: Ponnamma Divakaran Pradeep Kumar 
Published: November 2024

Purpose
This paper investigates how stockist brand equity is created in the unorganized pharma retail sector in emerging markets despite the absence of any proactive brand-building efforts by distribution firms (stockists). In addition, this study also aims to unravel the sources of stockist brand equity.

Design/methodology/approach
Drawing from grounded theory, a qualitative research design using semi-structured interviews was conducted, and a theoretical saturation approach was used for this purpose. The retailer–stockist (business-to-business [B2B]) relationship in the Indian pharmaceutical market context was used as the study context.

Findings
The findings show that in the absence of any brand-building activities, stockists’ sales representatives play an important role in creating stockist brand awareness. In addition, word of mouth from other retailers also plays a minor role. Rational and emotional brand associations which are strong, favorable and unique are created 1) directly by the services provided by stockists, which includes product availability, deliverability, accuracy in billing and batch numbers, credit facilities and discounts, handling issues such as product expiry, and 2) indirectly by the services provided by stockists’ sales representatives which includes their frequency of visits, proactive customer orientation rather than sales orientation, fulfilling commitments and relationship with retailers. The strength of the retailer–stockist (B2B) relationship also depends on retailer-driven factors and other external factors discussed in this study.

Social implications
Strong stockist brand equity helps build trust and loyalty with pharmacies, ensuring a consistent and timely supply of medicinal products, which will benefit their end consumers or society.

Originality/value
This study identifies the antecedents determining the strength of the retailer–stockist (B2B) relationship, a precursor for establishing retailer-based stockist brand equity in the unorganized sector. This study also highlights the consequences of establishing strong retailer-based stockist brand equity.
Understanding impulse buying in interest-based e-commerce: the role of content creativity
Authors: Gong Mengmeng , Liu Haixin 
Published: November 2024

PurposeThe popularisation of user-generated content has boosted the integration of social media with online retail, especially in the emerging context of interest-based e-commerce (IBEC). As the content brings new incentives for consumers’ impulsivity in consumption, it remains unclear understanding of the mechanism of impulse buying in IBEC from the current literature. This study aims to examine how content creativity encourages impulse buying intention though attitude, and whether the effect is moderated by consumers’ online shopping experience.Design/methodology/approachThis study administered a two-wave online survey to a purposive sample of 286 consumers with shopping experience in Douyin. The hypotheses and a moderated-mediation effect were tested using structural equation modelling in Mplus8.3.FindingsThe empirical results revealed that content creativity, including dual dimensions of relevance and divergence, can drive positive attitude towards platforms through the direct effect of subjective norm and mediation effect through perceived usefulness, which induces an urge to buy impulsively. The mediation effect is further moderated by consumers’ online shopping experience in IBEC.Originality/valueThis study expands the stream of impulse buying research in retailing by proposing a context of IBEC and bringing empirical evidence of the relationship between content and consumers’ urge to buy. The study provides strategic insights for retailers to achieve marketing value by managing consumers’ impulse purchases in IBEC.
From attraction to monetization: How do knowledge influencers trigger users’ willingness to subscribe to knowledge products?
Authors: Chen Xiaoyu , Chua Alton Y.K. 
Published: November 2024

PurposeThis study examines the phenomenon of “knowledge influencers,” individuals who convey expert information to non-expert audiences and attract users to subscribe to their self-created knowledge products. It seeks to address two research questions: (1) What are the antecedents that promote perceived attractiveness of knowledge influencers? and (2) How does perceived attractiveness of knowledge influencers affect users’ willingness to subscribe to knowledge products?Design/methodology/approachGuided by self-branding theory, which suggests that individuals strategically shape user perceptions and interactions to create an appealing image, the study employed a sequential mixed-methods approach. Qualitative interviews were conducted with knowledge influencers and their subscribers, followed by a quantitative survey of users with knowledge subscription experience to validate the findings.FindingsResults suggested that knowledge influencers could enhance their attractiveness to users by promoting perceived professionalism, perceived familiarity, and perceived connectedness. Perceived attractiveness of knowledge influencers could directly affect users’ willingness to subscribe or indirectly through the role of users’ attachment to knowledge influencers.Practical implicationsBy understanding the factors driving users’ subscription intentions, platform operators and influencers can refine their strategies to enhance user attachment and optimize monetization opportunities through personalized interactions and tailored content offerings.Originality/valueThis study contributes to the literature by elucidating the relationship between perceived attractiveness and users’ subscription intentions, offering new insights into the dynamics of online knowledge consumption.
Expatriate employees’ reactions to psychological contract breach: an empirical test of affective events theory
Authors: Ababneh Khaldoun I. , Ababneh Raed , Al Waqfi Mohammed , Dedousis Evangelos 
Published: November 2024

PurposeThis study draws on affective events theory (AET) to propose and examine a sequential process in which expatriate employees’ perceptions of psychological contract (PC) breaches impact their emotions (feelings of violation), which in turn influence their attitudes and ultimately their behaviors.Design/methodology/approachExpatriate employees (n = 228) working in the United Arab Emirates participated in an experiment with four employment scenarios created by manipulating transactional and relational PC promises. Participants, randomly assigned to each scenario, responded as if in a real job situation. Data analysis was performed using MANCOVA and structural equation modeling (SEM).FindingsEmploying an experimental design, the findings offer causal evidence that supervisors’ failure to fulfill employment promises adversely impacts expatriate employees’ perceptions of PC breaches, emotions, job satisfaction, organizational commitment, turnover intentions and performance. Consistent with the AET, the findings demonstrate that PC breaches impact expatriate employees’ emotions, which subsequently influence their attitudes and ultimately affect their behaviors.Practical implicationsThe study provides recommendations for organizations and managers to improve relationships with expatriate employees and suggests actions to lessen the adverse effects of PC breaches.Originality/valueTo our knowledge, this is the first study that examined the sequential process suggested by the AET in the context of PC and expatriation, establishing that PC breaches impact expatriate employees’ emotions, which in turn affect their attitudes and ultimately their behaviors.
Born digitals entry mode choice from a target market institutional and digitalization perspective
Authors: Schmitz Felix Rainer , Parente Ronaldo 
Published: November 2024

Purpose
The rise of digital technologies has led to the emergence of born digitals, which are firms distinguished by their digital business models and an early digitalization of their value chains. Despite the growing importance of these firms, their internationalization strategies, including the crucial choice of the most-suited foreign entry mode, have only been analyzed marginally by the extant literature. This paper aims to examine how born digitals select their entry mode and which context-specific modes are preferred.

Design/methodology/approach
By advancing the institutional entry mode approach of Meyer et al. (2009) with the digitalization conditions of the target market, the authors propose a theoretical entry mode framework for born digitals, in which the institutional market support and the digitalization degree simultaneously affect the entry mode decision.

Findings
The authors conclude with two main propositions, arguing that a joint venture and a digital entry are preferable under weak institutions and acquisitions and greenfield projects otherwise. Depending on a high digitalization degree, digital and greenfield entry modes are beneficial.

Originality/value
This paper contributes to the literature by creating an entry mode framework for born digitals and by introducing a digital entry mode.
Unraveling the Relationship Between High‐Performance Work Systems and Team Performance: The Contingent Role of Competitive Team Climate
Authors: Papalexandris Alexandros 
Published: November 2024

ABSTRACTThis study develops a multilevel moderated mediation model to explore the relationship between high‐performance work systems (HPWS) and team performance. Adopting a dialectical view of the effects of HPWS, it posits a dual ‐positive and negative‐ path between HPWS and team performance, which is jointly mediated by group coordination and relationship conflict. Furthermore, it theorizes that a competitive team climate can significantly influence these relationships. The proposed research model was tested using multisource data from a sample of 503 team members and 125 team managers from 58 firms. The results revealed that HPWS are positively associated with both group coordination and relationship conflict, and that both these relationships are moderated by a competitive team climate. This study contributes to the strategic human resource management literature by revealing that HPWS can be associated with team performance through both positive and negative intermediary mechanisms, and that team climate constitutes an important boundary condition that can amplify and inhibit the effect of HPWS on team performance.
Targeting NAMPT‐OPA1 for treatment of senile osteoporosis

Published: November 2024

AbstractSenescence of bone marrow mesenchymal stem cells (BMSCs) impairs their stemness and osteogenic differentiation, which is the principal cause of senile osteoporosis (SOP). Imbalances in nicotinamide phosphoribosyltransferase (NAMPT) homeostasis have been linked to aging and various diseases. Herein, reduction of NAMPT and impaired osteogenesis were observed in BMSCs from aged human and mouse. Knockdown of Nampt in BMSCs promotes lipogenic differentiation and increases age‐related bone loss. Overexpression of Nampt ameliorates the senescence‐associated (SA) phenotypes in BMSCs derived from aged mice, as well as promoting osteogenic potential. Mechanistically, NAMPT inhibits BMSCs senescence by facilitating OPA1 expression, which is essential for mitochondrial dynamics. The defect of NAMPT reduced mitochondrial membrane potential, interfered with mitochondrial fusion，and increased SA protein and phenotypes. More importantly, we have confirmed that P7C3, the NAMPT activator, is a novel strategy for reducing SOP bone loss. P7C3 treatment significantly prevents BMSCs senescence by improving mitochondrial function through the NAMPT‐OPA1 signaling axis. Taken together, these results reveal that NAMPT is a regulator of BMSCs senescence and osteogenic differentiation. P7C3 is a novel molecule drug to prevent the pathological progression of SOP.
Diagnosis, visibility, and “Illnesses You Have to Fight to Get”
Authors: Sherman Melina 
Published: November 2024

AbstractThis essay uses the author's lived experience as a person with bipolar disorder to explore the meaning of living with an “illness you have to fight to get.” Drawing on her own life trajectory, as well as on the work of Joseph Dumit and many other scholars who have written about chronic illness, the author reviews the main characteristics that belong to chronic, invisibilized conditions and the implications such characteristics have for the people who experience illness. After reviewing five key traits, the essay dives deeper into the promises and pitfalls of being diagnosed with “illnesses you have to fight to get.” The essay ends with a call to action and ideas for how scholars, advocates, others can help empower and support the ongoing struggle of those who live with invisibilized chronic illnesses.
