Imported inputs, firms' capabilities and productivity: evidence from emerging South Asian economies
Authors: Luqman Muhammad , Murtaza Ghulam 
Published: June 2023

PurposeThe main purpose of this study is to examine the impact of imported inputs on firms' productivity in selected South Asian economies, namely Pakistan, India and Bangladesh. Furthermore, this study explores the complementarity between firms' capabilities and imported inputs in an augmented productivity framework.Design/methodology/approachA dataset comprising 7117 manufacturing firms of selected South Asian economies was taken from the World Bank for 2013 and 2014. The empirical analysis was based on stochastic frontier models, the ordinary least square method and instrumental variable estimation techniques.FindingsThe empirical results show that imported inputs have positive and significant effects on the firms' productivity in the selected countries. Moreover, the study findings demonstrate that firms' capabilities play a complementary role in expanding the firms' production frontier.Practical implicationsThe study outcomes suggest that reducing tariffs on imported inputs will enhance the firms' productivity in the selected emerging economies. However, the study further finds that the potential gain of imported inputs is conditional on the firm's capabilities. It implies that firms operating in these countries can improve their performance by allocating more resources to capabilities, such as workers’ training, management and internal R&D effort.Originality/valueThe existing literature on the subject is sceptical about the positive impact of imported inputs on firms' productivity in the case of developing countries. In this regard, the shortage of skilled labour and firms' capabilities are compelling rationales that need to be explored. Thus, the potential contribution of the study lies in explaining the moderating role of firm's capabilities operating in the selected emerging economies in the nexus of imported inputs and productivity.

Published: June 2023

PurposeUsing the conservation of resources (COR) theory, the present study aims to examine the role of participative leadership in frontline service employees (FLEs)’ service recovery performance. The present study also tests FLEs’ role breadth self-efficacy (RBSE) as a theoretically relevant mediator and FLE trait mindfulness as an important moderator.Design/methodology/approachData were collected using time-lagged (three rounds, two weeks apart) from two sources (193 FLEs and 772 customers, who experienced a service failure). Structural equation modeling (Mplus, 8.6) was employed to analyze the data.FindingsThe results revealed that participative leadership was positively associated with FLEs service recovery performance, both directly and indirectly, via RBSE. The results also showed that FLE trait mindfulness moderated the link of participative leadership with RBSE and the indirect association of participative leadership with service recovery performance, via RBSE.Practical implicationsThis study suggests that organizational leaders who exhibit participative leadership behavior are valuable for organizations. By demonstrating such behaviors, they boost FLEs' RBSE, which in turn improves their service recovery performance.Originality/valueThe present work makes important contributions to the literature on service recovery performance by foregrounding two important yet overlooked antecedents (participative leadership and RBSE) of FLE service recovery performance. The present work also contributes to the nascent literature on the antecedents and outcomes of RBSE in service contexts.

Authors: Zhao Xin , Fu Na , Liang Xiaoning 
Published: June 2023

PurposeTeam leaders play a vital role in achieving superior team performance. However, their role in implementing the organizational customer orientation strategy is not well understood. Drawing on social exchange theory, this study investigates how team leader customer orientation affects team customer orientation climate and team performance (i.e. customer satisfaction) as well as the moderating role of transformational leadership in such effect.Design/methodology/approachThis study builds on survey data collected from matched team leaders, employees and customers nested in 81 service teams and employs hierarchical multiple regression analysis to test the hypotheses.FindingsThe findings indicate that team leader customer orientation increases team customer orientation climate, which leads to a higher level of customer satisfaction. Leaders' transformational leadership moderates the link between a leader customer orientation and team customer orientation climate in an unexpected way. When a team leader is transformational, the team customer orientation climate is enhanced, regardless of the level of team leader customer orientation. When a team leader's transformational leadership is low, the higher leader customer orientation is and the higher team customer orientation climate is.Originality/valueThis study contributes to the customer orientation, transformational leadership and service literature by unraveling team leaders' roles in boosting team customer orientation climate and team effectiveness.
Can a student-managed fund transfer expert financial knowledge? Examining trustee voting consensus in a student-managed investments program
Authors: Belcher Lawrence J. , Belcher Landon J. 
Published: June 2023

PurposeThe “experience is the best teacher” model assumes that acquiring expertise in a given domain reduces biases. Research in expert knowledge in investment decisions has shown better ability to produce improved results in asset selection or portfolio returns. Universities created student-managed investment funds (SMIFs) to train students in portfolio management as fiduciaries. However, analyses of the effectiveness of the SMIF as a medium for expert knowledge transfer have not been done.Design/methodology/approachThe authors’ analyze an SMIF's structure against established models of expert knowledge transfer, using the voting patterns of the trustees of the fund from the recorded minutes of the fund's meetings to show the fund's structure and outcomes demonstrate effective knowledge transfer. Voter consensus between faculty and student trustees is one proxy the authors use for knowledge transfer.FindingsConsensus between faculty and students was uniformly high across all recommendations. Chi-square tests were employed to test for independence between approval of recommendation and level of consensus, showing dependence in most cases. Analysis of sale returns over the 12-year sample period showed significantly better performance of asset sales over relevant benchmarks for both equity and fixed income portfolios.Originality/valueMost analyses of SMIF structure concentrate on well-known issues with things like student turnover, summers or other structural issues. Performance is evaluated based on returns. This study looks at the SMIF as an expert knowledge transfer medium and examines expert/novice decision approval in terms of knowledge transfer.

Authors: Shaikh Mohammad Farhan , K Nallasivam 
Published: June 2023

PurposeIn this study, a finite element model of a box-girder bridge along with the railway sub-track system is developed to predict the static behavior due to different combinations of the Indian railway system and free vibration responses resulting in different natural frequencies and their corresponding mode shapes.Design/methodology/approachThe modeling and evaluation of the bridge and sub-track system were performed using non-closed form finite element method (FEM)-based ANSYS software.FindingsFrom the analysis, the worst possible cases of deformation and stress due to different static load combinations were determined in the static analysis, while different natural frequencies were determined in the free vibrational analysis that can be used for further analysis because of the dynamic effect of the train vehicle.Research limitations/implicationsThe scope of the current investigation is confined to the structure's static and free vibration analysis. However, this study will help the designers obtain relevant information for further analysis of the dynamic behavior of the bridge model.Originality/valueIn static analysis, the maximum deformation of the bridge deck was found to be 10.70E-03m due to load combination 5, whereas the maximum natural frequency for free vibration analysis is found to be 4.7626 Hz.

Published: June 2023

Purpose
This paper aims to focus on the spatial docking task of unmanned vehicles under ground conditions. The docking task of military unmanned vehicle application scenarios has strict requirements. Therefore, how to design a docking robot mechanism to achieve accurate docking between vehicles has become a challenge.

Design/methodology/approach
In this paper, first, the docking mechanism system is described, and the inverse kinematics model of the docking robot based on Stewart is established. Second, the genetic algorithm-based optimization method for multiobjective parameters of parallel mechanisms including workspace volume and mechanism flexibility is proposed to solve the problem of multiparameter optimization of parallel mechanism and realize the docking of unmanned vehicle space flexibility. The optimization results verify that the structural parameters meet the design requirements. Besides, the static and dynamic finite element analysis are carried out to verify the structural strength and dynamic performance of the docking robot according to the stiffness, strength, dead load and dynamic performance of the docking robot. Finally, taking the docking robot as the experimental platform, experiments are carried out under different working conditions, and the experimental results verify that the docking robot can achieve accurate docking tasks.

Findings
Experiments on the docking robot that the proposed design and optimization method has a good effect on structural strength and control accuracy. The experimental results verify that the docking robot mechanism can achieve accurate docking tasks, which is expected to provide technical guidance and reference for unmanned vehicles docking technology.

Originality/value
This research can provide technical guidance and reference for spatial docking task of unmanned vehicles under the ground conditions. It can also provide ideas for space docking missions, such as space simulator docking.
Hardness and modulus programmable tuning for silicone 3D printing device and experiment
Authors: Jiao Zhiwei , Zhuang Zhongyu , Hu Li , Sun Ce , Yu Yuan , Yang Weimin 
Published: June 2023

Purpose
The purpose of this study was to fabricate silicone products that had different hardnesses and moduli, thus partially addressing the limitations of homogeneous materials whose deformation depends on altered structure or dimensions, and to provide new dimensions for the design of silicone soft structures.

Design/methodology/approach
A soft material three-dimensional printing platform with a dual-channel printing capability was designed and built. Using the material extrusion method, material screening was first performed using single-channel printing, followed by dual-channel-regulated printing experiments on products having different hardness and modulus values.

Findings
The proportion of additives has an effect on the accuracy of the printed product. Material screening revealed that Sylgard 527 and SE 1700 could be printed without additives. The hardness and mechanical properties of products are related to the percentage in their composition of hard and soft materials. The hardness of the products could be adjusted from 26A to 42A and the Young’s modulus from 0.875 to 2.378 Mpa.

Originality/value
Existing silicone products molded by casting or printing are mostly composed of a single material, whose uniform hardness and modulus cannot meet the demand for differentiated deformation in the structure. The existing multihardness silicone material printing method has the problems of long material mixing time and slow hardness switching and complicated multi-extrusion head switching. In this study, a simple, low-cost and responsive material extrusion-based hardness programmable preparation method for silicone materials is proposed.
Study on dynamic response of high speed train window glass under tunnel aerodynamic effects
Authors: Liu Xiaogen , Qi Shuang , Wan Detian , Zheng Dezhi 
Published: June 2023

PurposeThis paper aims to analyze the bearing characteristics of the high speed train window glass under aerodynamic load effects.Design/methodology/approachIn order to obtain the dynamic strain response of passenger compartment window glass during high-speed train crossing the tunnel, taking the passenger compartment window glass of the CRH3 high speed train on Wuhan–Guangzhou High Speed Railway as the research object, this study tests the strain dynamic response and maximum principal stress of the high speed train passing through the tunnel entrance and exit, the tunnel and tunnel groups as well as trains meeting in the tunnel at an average speed of 300 km·h-1.FindingsThe results show that while crossing the tunnel, the passenger compartment window glass of high speed train is subjected to the alternating action of positive and negative air pressures, which shows the typical mechanic characteristics of the alternating fatigue stress of positive-negative transient strain. The maximum principal stress of passenger compartment window glass for high speed train caused by tunnel aerodynamic effects does not exceed 5 MPa, and the maximum value occurs at the corresponding time of crossing the tunnel groups. The high speed train window glass bears medium and low strain rates under the action of tunnel aerodynamic effects, while the maximum strain rate occurs at the meeting moment when the window glass meets the train head approaching from the opposite side in the tunnel. The shear modulus of laminated glass PVB film that makes up high speed train window glass is sensitive to the temperature and action time. The dynamically equivalent thickness and stiffness of the laminated glass and the dynamic bearing capacity of the window glass decrease with the increase of the action time under tunnel aerodynamic pressure. Thus, the influence of the loading action time and fatigue under tunnel aerodynamic effects on the glass strength should be considered in the design for the bearing performance of high speed train window glass.Originality/valueThe research results provide data support for the analysis of mechanical characteristics, damage mechanism, strength design and structural optimization of high speed train glass.

Authors: Smith Sam 
Published: June 2023

Purpose
The purpose of this paper was to help the reader understand how technology is crucial to the effective management of non-traditional workforces. Over the past year, the UK labour market, much like the rest of the world, has found itself dealing with challenges at every turn. Whether significant interest rate hikes in response to surging inflation, the energy crisis and global supply chain issues largely influenced by the escalation of the war in Ukraine or rapid changes in working attitudes and cultures, businesses are increasingly under a lot of pressure.

Design/methodology/approach
This paper was designed and written based on the findings of Magnit’s Winter 2023 Europe Labour Market Report.

Findings
Consequently, organisations have to adapt their attitudes to the hiring and management of staff, whether that be leveraging temporary workers, re-evaluating pay rates or expanding benefits.

Originality/value
Critical to this endeavour is to implement an effective workforce management strategy that is embedded into all decision-making processes.
Notch-band eliminator wideband CSRR loaded monopole fractal antenna for ISM and PCS communications
Authors: Varshney Atul , Sharma Vipul , Neebha T. Mary , Kumari N. Prasanthi 
Published: June 2023

Purpose
This paper aims to present a low-cost, edge-fed, windmill-shaped, notch-band eliminator, circular monopole antenna which is practically loaded with a complementary split ring resonator (CSRR) in the middle of the radiating conductor and also uses a partial ground to obtain wide-band performance.

Design/methodology/approach
To compensate for the reduced value of gain and reflection coefficient because of the full (complete) ground plane at the bottom of the substrate, the antenna is further loaded with a partial ground and a CSRR. The reduction in the length of ground near the feed line improves the impedance bandwidth, and introduced CSRR results in improved gain with an additional resonance spike. This results in a peak gain 3.895dBi at the designed frequency 2.45 GHz. The extending of three arms in the circular patch not only led to an increase of peak gain by 4.044dBi but also eliminated the notch band and improved the fractional bandwidth 1.65–2.92 GHz.

Findings
The work reports a –10dB bandwidth from 1.63 GHz to 2.91 GHz, which covers traditional coverage applications and new specific uses applications such as narrow LTE bands for future internet of things (NB-IoT) machine-to-machine communications 1.8/1.9/2.1/2.3/2.5/2.6 GHz, industry, automation and business-critical cases (2.1/2.3/2.6 GHz), industrial, society and medical applications such as Wi-MAX (3.5 GHz), Wi-Fi3 (2.45 GHz), GSM (1.9 GHz), public safety band, Bluetooth (2.40–2.485 GHz), Zigbee (2.40–2.48Ghz), industrial scientific medical (ISM) band (2.4–2.5 GHz), WCDMA (1.9, 2.1 GHz), 3 G (2.1 GHz), 4 G LTE (2.1–2.5 GHz) and other personal communication services applications. The estimated RLC electrical equivalent circuit is also presented at the end.

Practical implications
Because of full coverage of Bluetooth, Zigbee, WiFi3 and ISM band, the proposed fabricated antenna is suitable for low power, low data rate and wireless/wired short-range IoT-enabled medical applications.

Originality/value
The antenna is fabricated on a piece (66.4 mm × 66.4 mm × 1.6 mm) of low-cost low profile FR-4 epoxy substrate (0.54

λg × 0.54

λg) with a dielectric constant of 4.4, a loss tangent of 0.02 and a thickness of 1.6 mm. The antenna reflection coefficient, impedance and VSWR are tested on the Keysight technology (N9917A) vector network analyzer, and the radiation pattern is measured in an anechoic chamber.
Women's representation in top management teams of emerging markets' multinationals in developed countries: A legitimacy perspective
Authors: Saeed Abubakr , Riaz Hammad , Riaz Safa 
Published: June 2023

AbstractNumerous studies have documented the existence of legitimacy challenges that emerging markets multinational enterprises (EMNEs) face in foreign markets due to their national origin. However, there is limited understanding of the EMNEs' strategic responses to offset these country‐of‐origin related disadvantages. In this study, we conceptualize gender diversity management (GDM) as a strategic response of EMNEs to mitigate the legitimacy challenges in developed countries. Specifically, we argue that emerging markets firms increase women's representation in top management teams to overcome the liability of origin. We use legitimacy perspective to examine the effect of pervasiveness of institutional voids in emerging markets on women's representation in top management teams of EMNEs. Based on subsidiary‐level panel data of EMNEs from 20 emerging markets operating in developed countries from 2010 to 2019, our results show strong and robust evidence indicating that the pervasiveness of institutional voids at home is positively related to women's representation in top management teams of emerging markets firms. Additional analyses demonstrate that duration in the foreign market, market‐seeking intent, and state ownership further magnify this effect. These findings, besides significantly adding to the international human resource management literature, have managerial implications.

AbstractBackgroundGlycemic gap, as a novel index of acute glycemic excursion, is associated with poor prognosis of different diseases. This study aimed to explore the association of the glycemic gap with long‐term stroke recurrence in patients with ischemic stroke.MethodsThis study included patients with ischemic stroke from the Nanjing Stroke Registry Program. The glycemic gap was calculated by subtracting the estimated average blood glucose from the blood glucose at admission. Multivariable Cox proportional hazards regression analysis was performed to explore the association between the glycemic gap and the risk of stroke recurrence. The Bayesian hierarchical logistic regression model was used to estimate the effects of the glycemic gap on stroke recurrence stratified by diabetes mellitus and atrial fibrillation.ResultsAmong 2734 enrolled patients, 381 (13.9%) patients experienced stroke recurrence during a median follow‐up of 3.02 years. In multivariate analysis, glycemic gap (high group vs. median group) was associated with significantly increased risk for stroke recurrence (adjusted hazard ratio, 1.488; 95% confidence interval, 1.140–1.942; p = .003) and had varying effects on stroke recurrence depending on atrial fibrillation. The restricted cubic spline curve showed a U‐shaped relationship between the glycemic gap and stroke recurrence (p = .046 for nonlinearity).ConclusionOur study found that the glycemic gap was significantly associated with stroke recurrence in patients with ischemic stroke. The glycemic gap was consistently associated with stroke recurrence across subgroups and had varying effects depending on atrial fibrillation.
Economic consequences of announcing strategic alternatives: A voluntary disclosure's benefits and costs
Authors: Zha Giedt Jenny 
Published: June 2023

AbstractThis study examines the benefits and costs to a company of publicly announcing that it is seeking a potential sale or merger. I find that the announcement leads to increased market attention and a more robust merger and acquisition sales process—the benefits of improved transparency. However, I also find evidence of the announcement alienating stakeholders and increasing business disruption—the costs of credible disclosure. I document the countervailing valuation effects of these benefits and costs, where the net valuation effect depends on whether the company is subsequently acquired. This research is important because it (1) demonstrates the disclosure's impact on the company through multiple channels, (2) estimates the valuation effects, and (3) identifies key considerations for investors and other stakeholders who bear the consequences of such a disclosure.
