AbstractThe O-linked N-acetylglucosamine (O-GlcNAc) transferase (OGT) mediates intracellular O-GlcNAcylation modification, whose function and substrates have entranced biologists and chemists alike. O-GlcNAcylation occurs on Ser/Thr residues and takes part in a vast array of physiological processes. OGT is essential for dividing mammalian cells, and it underscores many human diseases. Yet many of its fundamental substrates in the cell division process remains to be unveiled. Here we focus on its effect on Polo-like kinase 1 (PLK1), a mitotic master kinase that governs DNA replication, mitotic entry, chromosome segregation and mitotic exit. We found that PLK1 interacts with OGT and is O-GlcNAcylated. By utilizing stepped collisional energy/higher-energy collisional dissociation (sceHCD) mass spectrometry (MS) and mutagenesis studies, the critical O-GlcNAc site is located to be Thr291. Interestingly, T291N is a uterine carcinoma mutant in the TCGA database. Biochemical assays show that T291A and T291N both increase PLK1 stability. Using stable H2B-GFP cells, we show that PLK1-T291A and -T291N mutants display chromosome segregation defects, and result in misaligned and lagging chromosomes. In mouse xenograft models, we demonstrate that the O-GlcNAc-deficient PLK1-T291A and -T291N mutants would enhance uterine carcinoma in animals. Hence, we propose that OGT partially exerts its mitotic function through O-GlcNAcylation of PLK1, and sceHCD MS might be a new method to reveal many more O-GlcNAcylation substrates.

Published: August 2022

The novel quaternary thiogermanate Li4CdGe2S7 (tetralithium cadmium digermanium heptasulfide) was discovered from a solid-state reaction at 750 °C. Single-crystal X-ray diffraction data were collected and used to solve and refine the structure. Li4CdGe2S7 is a member of the small, but growing, class of I4–II–IV2–VI7 diamond-like materials. The compound adopts the Cu5Si2S7 structure type, which is a derivative of lonsdaleite. Crystallizing in the polar space group Cc, Li4CdGe2S7 contains 14 crystallographically unique ions, all residing on general positions. Like all diamond-like structures, the compound is built of corner-sharing tetrahedral units that create a relatively dense three-dimensional assembly. The title compound is the major phase of the reaction product, as evidenced by powder X-ray diffraction and optical diffuse reflectance spectroscopy. While the compound exhibits a second-harmonic generation (SHG) response comparable to that of the AgGaS2 (AGS) reference material in the IR region, its laser-induced damage threshold (LIDT) is over an order of magnitude greater than AGS for λ = 1.064 µm and τ = 30 ps. Bond valence sums, global instability index, minimum bounding ellipsoid (MBE) analysis, and electronic structure calculations using density functional theory (DFT) were used to further evaluate the crystal structure and electronic structure of the compound and provide a comparison with the analogous I2–II–IV–VI4 diamond-like compound Li2CdGeS4. Li4CdGe2S7 appears to be a better IR nonlinear optical (NLO) candidate than Li2CdGeS4 and one of the most promising contenders to date. The exceptional LIDT is likely due, at least in part, to the wider optical bandgap of ∼3.6 eV.
Global cities and multilatinas: the search for global cities-specific advantages, establishment and ownership entry modes
Authors: Kaltenecker Evodio , Montoya Miguel A. 
Published: August 2022

Purpose
This paper aims to study the internationalization path of emerging market multinational enterprises (EMNEs) in their international expansion through the global cities (GCs) phenomenon.

Design/methodology/approach
The authors used a quantitative approach to identify the most used ownership and entry modes, the preferred economic sectors and the level of interconnectedness of GCs.

Findings
The manuscript identified the predominance of the tertiary sector in the selection of GCs as foreign direct investment destinations. Second, the acquisition is the preferred entry mode regardless of the connectivity of the GC and the country of origin of the EMNE. The third is the use of wholly-owned subsidiaries as the preferred ownership mode. Finally, market-seeking is the main driver for the internationalization of Latin American EMNE. Consequentially, some GCs-specific advantages remain untapped by Latin American EMNE.

Research limitations/implications
This manuscript considered each investment into a global city as a single step, although some acquisitions occurred incrementally through several small investments.

Practical implications
The authors developed a road map for the internationalization of Latin American EMNEs through GCs, acquisitions and wholly-owned subsidiaries. Finally, service-oriented EMNEs, such as IT and financial services, target locations with high interconnectedness to maximize the benefits of GCs-specific advantages.

Originality/value
The authors pointed out that market-seeking, not resource-seeking or efficiency-seeking is the primary driver of the internationalization of EMNE into global cities.

Authors: Stefanidis Abraham , King-Sears Margaret E. , Gilic Lina , Strogilos Vasilis 
Published: August 2022

PurposeThe purpose of this study is to investigate the relationships between (1) employed parents' work–family conflict (WFC), (2) their children with disabilities' support needs, (3) their children's age, and (4) those parents' levels of school engagement.Design/methodology/approachData were collected from 193 US parents of children with disabilities who completed a survey regarding work and family strain as well as school engagement. Descriptive statistical and correlational analyses were used, followed by moderated regression analysis.FindingsResults indicate that higher levels of WFC have a negative impact on parents' school engagement. Similarly, children with disabilities' increased needs for parental support have a negative impact on school engagement. Moreover, the age of children with disabilities holds a moderating role in the relationship between support needs and school engagement.Research limitations/implicationsHuman resource managers can acquire information regarding employed parents of children with disabilities' increased support needs and formalize flexible policies leading to supportive workplace cultures. School personnel can instigate a range of options that facilitate parents' school engagement, such as maximizing use of technology via virtual meetings and activities.Originality/valueThese innovative findings contribute to theoretical underpinnings in work and family strain research as well as conservation of resources theory, given the lack of previous empirical work specific to children with disabilities and their employed parents.

Human resources under technological transformation: what HR professionals believe in an international scale
Authors: Mantzaris Konstantinos , Myloni Barbara 
Published: August 2022

PurposeThis paper examines the beliefs of human resource professionals (HRPs) regarding the impact of Industry 4.0 on organizations in terms of readiness for human resources management (HRM) transformation, the challenges of a potential new legal and financial framework, the new means on performance management and automation, and finally the decision-making process in the era of human-machine cooperation.Design/methodology/approachThe authors analyzed a sample of 251 HRPs from 11 different countries divided into 4 cultural clusters to explore their attitude to incorporate new practices to the HR field because of technological development. The paper explores HRPs' beliefs in a legal and financial context, performance management issues, and the impact of automation on the decision-making process. Furthermore, the authors perform a cross-cultural comparison analysis to examine potential significant differences between cultural clusters.FindingsHRPs are aware of how technology adoption is affecting work environment and they highlight the importance of human resources (HR) for businesses, despite the global trend of extensive machinery exploitation. Interestingly, our results suggest that overall globalization, common knowledge, and internationalized practices lead to homogeneity for most issues under study.Originality/valueTo the best of the authors' knowledge, there has not been any comprehensive study exploring and analyzing the effects of Industry 4.0 on HRPs perceptions in the context of a dynamic HR environment influenced by technological transformation. The study shows that HRPs' present similar perspectives for most issues addressed, irrespective of cultural characteristics of HRPs. Hence, this paper generates some important insights in an attempt to build a framework for enhancing HR in this new era.

Environmentally specific transformational leadership and pro-environmental behavior: an empirical analysis of energy sector
Authors: Soni Monika 
Published: August 2022

Purpose
Although decades of research on transformational leadership have resulted in a firm understanding of its consequences, the impact of environmental-conscious transformational leader on positive employee outcomes and underlying mechanism in environmental leadership–outcome relationship is not well examined. This study aims to examine a moderated mediation model of effects of environmental consciousness (EC) on the mediating role of perceived corporate social responsibility (PCSR) in transformational leadership (ETFL) and pro-environmental behavior (PEB) relationship in energy-intensive industries.

Design/methodology/approach
In total, 320 self- reported questionnaires were collected from employees working in different Indian organizations across different sectors. All measures used in this survey were adopted from well-established scales. To minimize the effects of common method variance arising, the survey questionnaires were administered to the participants in two stages (with a gap of 14 days), with antecedents separated from outcomes. Partial least squares (PLS) structural equation modeling and SPSS-process macro were applied for testing the hypothesized model.

Findings
The results revealed that ETFL positively correlated with PEB. The hypothesized moderated mediation condition was supported as the results suggest that PCSR mediated the ETFL–PEB relationship, and EC moderated this mediating pathway; i.e. indirect effects of ETFL on employee PEB via PCSR were stronger for employees with high EC.

Practical implications
In particular, this research provides implications for training and development of leaders. The study indicates the importance of environmental-conscious leaders in enhancing perceived PCSR and PEB of employees. Likewise, the finding found that PCSR mediates the ETFL and PEB relationship. Moreover, the indirect effect of ETFL on PEB through PCSR moderated by EC highlights the importance of managing and ensuring effective leader–employee relationship that facilitates ecofriendly initiatives.

Originality/value
The study is based on the data collected from energy-intensive industries. Thus, it provides insights into the role and importance of green leadership and green behavior in energy industries. It is one of the few studies in the energy-intensive industry in India that help the researcher to delve into future research on the same.
The circularity of product-service systems: the role of macro-, meso- and micro-level contextual factors
Authors: Kühl Carl , Skipworth Heather Dawn , Bourlakis Michael , Aktas Emel 
Published: August 2022

PurposeThis paper aims to examine the relationships between macro-, meso- and micro-level contextual factors that enable or inhibit the contribution of product service systems (PSS) to circularity. It is informed by the natural resource-based view (NRBV) and the multi-level perspective as theoretical lenses.Design/methodology/approachA theory elaboration approach is used through three in-depth case studies of UK and German manufacturers. Case studies provide use- and result-oriented PSS for personal computers, power tools and wind turbines. Multiple sources of evidence, including 20 semi-structured interviews, company documents and quantitative data, are triangulated to improve the validity of the results.FindingsEmpirical evidence for relationships between macro-, meso- and micro-level contextual factors show significant barriers to the extending and cycling of resource loops, primarily through maintenance, repairs and refurbishment. A firm’s environmental awareness has a determining role in the contribution of PSS to circularity. The evidence from two use-oriented PSS reveals different circularity maturity levels.Originality/valueThis research makes three key contributions. Firstly, it elaborates on NRBV by showing that a firm’s environmental awareness determines product stewardship. The type of product stewardship practices depends on the enabling and inhibiting effects of macro- and meso-level factors. Secondly, it shows that use-oriented PSS have different circularity profiles and proposes three circularity maturity levels. Finally, it provides an empirically validated framework of macro-, meso- and micro-level enablers and barriers and how they interact to enable or inhibit circularity in PSS.
Braking-experimental study on the relationship between friction material type and brake disc temperature
Authors: Chen Youjie , Gao Fei , Fu Rong , Su Linlin , Han Xiaoming , Yang Junying 
Published: August 2022

Purpose
This study aims to clarify the relationship of friction material type and brake disc temperature through braking experiment.

Design/methodology/approach
The braking performances of resin materials (RM), semimetallic materials (SM) and copper-based powder metallurgy materials (PM) friction blocks mating with forged steel brake disc were examined based on TM-I-type reduced-scale inertial braking dynamometer. The brake disc surface temperature was recorded by infrared thermal camera during braking.

Findings
Experimental results indicate that the thermal wear resistance of three friction materials differs with mental content, resulting in the deviation of pad-disc system contact state during braking, thus forming different temperature distribution on the brake disc surface. The peak temperature on the disc face of RM (190°C) is 36.6% and 45.4% lower than that of PM (300°C) and SM (348°C) at 160 km/h. The maximum radial temperature deviation of PM (35°C) is approximately three times than that of RM (12°C) and 40% higher than that of SM (25°C) at 50 km/h, whereas the maximum temperature deviation of SM (97°C) is six times than that of RM (16°C) and 31% higher than that of PM (74°C) at 160 km/h.

Originality/value
The effect of friction material type on the disc surface temperature distribution is revealed, which provides a meaningful reference for the design of brake friction pairs and choice of brake pad materials.
Design of wireless in-pipe inspection robot for image acquisition
Authors: Wu Kunlun , Sang Haifeng , Xing Yanhao , Lu Yao 
Published: August 2022

Purpose
Pipeline robots are often used in pipeline non-destructive testing. Given the need for long-range in-pipe inspections, this study aims to develop a wireless in-pipe inspection robot for image acquisition.

Design/methodology/approach
In this paper, an in-pipe robot with a new mechanical system is proposed. This system combines a three-arm load-bearing structure with spring sleeves and a half-umbrella diametric change structure, which can ensure the stability of the camera when acquiring images while maintaining the robot’s flexibility. In addition, data were transmitted wirelessly via a system that uses a 433 MHz ultra-high frequency and wireless local-area network–based image transmission system. Software and practical tests were conducted to verify the robot’s design. A preliminary examination of the robot’s cruising range was also conducted.

Findings
The feasibility of the robot was demonstrated using CATIA V5 and MSC ADAMS software. The simulation results showed that the centre of mass of the robot remained in a stable position and that it could function in a simulated pipeline network. In the practical test, the prototype functioned stably, correctly executed remote instructions and transmitted in near real-time its location, battery voltage and the captured images. Additionally, the tests demonstrated that the robot could successfully pass through the bends in a 200-mm-wide pipe at any angle between 0° and 90°. In actual wireless network conditions, the electrical system functioned for 44.7 consecutive minutes.

Originality/value
A wheeled wireless robot adopts a new mechanical system. For inspections of plastic pipelines, the robot can adapt to pipes with diameters of 150–210 mm and has the potential for practical applications.
A contextual study of employee turnover intention in Vietnam F&B service sector: an integrative perspective
Authors: Han Jung Woo 
Published: August 2022

PurposePrevious studies on employee turnover did not explore the contextual differences of emerging markets such as Vietnam. As Vietnam is a fast-growing new tiger economy with a high inflow of foreign direct investment, contextual analysis needs to be conducted to handle rising HR issues in the region. The current study aims to analyze paths to employee turnover intention through an integrated model covering factors on individual, team, and organizational levels to understand the contextual difference in the Vietnam F&B service industry.Design/methodology/approachA mixed method was used based on quantitative and qualitative data from three organizations. For the quantitative analysis, a path model was developed and analyzed by SEM-PLS (Smart PLS) based on a sample size of 354. For the qualitative analysis, 32 semi-structured interviews were conducted to explore the contextual understanding in the regional context.FindingsAlthough the current study confirms that the paths among the three levels show the turnover factors developed in the previous study still applicable to the Vietnam context, the strengths and relationships among the team and individual levels imply that the Vietnamese context created a unique HRM environment forming different paths to reach employee turnover decisions.Originality/valueThe findings contributed to the literature on employee turnover by developing an integrated model of employee turnover encompassing the three levels, suggesting the different local contexts formed unique paths to employee turnover decisions.
