Authors: Dey Sima Rani 
Published: April 2019

PurposeThe purpose of this study is to examine the causal relationship between per capita electricity consumption (PCEC) and per capita gross national income (GNI) (PCGNI) in Bangladesh for the period of 1971-2014.Design/methodology/approachVector error correction modeling approach.FindingsThe study reveals that positive short-run unidirectional causal flow running between PCEC to PCGNI without feedback which implies that an increase in electricity consumption promptly affects economic activity. The results of both long-run and joint causality yield strong evidence of bidirectional causal relationship between PCEC and per capita real GNI with feedback.Originality/valueTherefore, both electricity generation and conservation policy will be effective for Bangladesh economy. So, smooth supply of electricity is necessary to meet the growing electricity demand for consumption; consequently, it will lead to sustain of growth and take it even higher level.

Authors: Polyviou Mikaella , Croxton Keely L. , Knemeyer A. Michael 
Published: April 2019

PurposeThe purpose of this paper is to explore resources or capabilities that enable medium-sized firms to be resilient, namely, to avoid and recover from supply chain disruptions.Design/methodology/approachA case-study method is employed with four medium-sized manufacturing firms headquartered in the USA that have global supply chains. Data are collected from semi-structured interviews with key informants from diverse functions and managerial levels, archival documents, observation and a resilience assessment.FindingsInternal social capital emerged as a resilience-enhancing resource, comprising: structural capital grounded in small network size, geographical proximity among decision makers and low hierarchy; relational capital grounded in close relationships, commitment and respect; and cognitive capital grounded in long employee tenure.Originality/valueThis is the first paper in the supply chain management literature to examine the resilience of medium-sized firms, an under-researched context. It is also the first paper to introduce internal social capital as a resilience-enhancing resource. Hence, this is among the few papers to propose a resilience-enhancing resource rooted not in a firm’s supply chain operations but its human resources. This paper, moreover, identifies several facets of internal social capital within medium-sized firms. Finally, the paper makes several managerial contributions.
Erosion wear performance of Ni-Cr-O and NiCrBSiFe-WC(Co) composite coatings deposited by HVOF technique
Authors: Singh Jashanpreet , Kumar Satish , Mohapatra S.K. 
Published: April 2019

Purpose
This study/paper aims to investigate the erosion wear performance of Ni-based coatings [Ni-Cr-O and NiCrBSiFe-WC(Co)] under sand-water slurry conditions.

Design/methodology/approach
A high-velocity oxy-fuel (HVOF) process was used to deposit the Ni-based coatings [Ni-Cr-O and NiCrBSiFe-WC(Co)] on the surface of stainless steel (SS 316L) substrate. A Ducom TR-41 erosion tester was used to conduct the tribological experiments on bare/HVOF coated SS 316L. The erosion wear experiments were carried out for different time durations (1.30-3.00 h) at different impact angles (0-60°) by running the pot tester at different rotational speeds (600-1,500 rev/min). The solid concentration of sand slurry was taken in the range of 30-60 Wt.%. The surface roughness of Ni-based coated surfaces was also measured along the transverse length of the specimens.

Findings
Results show the arithmetic mean roughness (Ra) values of Ni-Cr-O and NiCrBSiFe-WC coated SS-316L were 7.04 and 6.67 µm, respectively. The erosion wear SS-316L was almost 3.5 ± 1.5 times greater than that of the NiCrBSiFe-WC coatings. NiBCrSi-WC(Co) sprayed SS-316L showed lower erosion wear than Ni-Cr-O sprayed SS-316L. Microscopically, the eroded Ni-Cr-O coating underwent plowing, microcutting and craters. Ni-Cr-O coating have shown the ductile nature of erosion wear mechanism. NiBCrSi-WC(Co) surface underwent craters, plowing, carbide/boride pullout, fractures and intact. Erosion wear mechanisms on the eroded surface of NiBCrSi-WC(Co) were neither purely ductile nor brittle.

Practical implications
It is a useful technique to estimate the erosion wear of hydraulic machinery coated with Ni-based coatings imposed under mining conditions.

Originality/value
The erosion wear performance of HVOF-sprayed Ni-Cr-O and NiCrBSiFe-WC(Co) powders was investigated through extensive experimentation, and the results are well supported by scanning electron micrographs and 3D topology.

Authors: Chammas Cristiane Benedetti , Hernandez José Mauro da Costa 
Published: April 2019

Purpose
The purpose of this study is to investigate the influence of transformational and instrumental leadership on the individual performance of the employee and the financial performance in Brazilian startups.

Design/methodology/approach
The adopted methodological construction strategy was structural equation modeling, with the purpose of applying the model to primary data collected from a sample of leaders of Brazilian startups (n = 126).

Findings
Results suggest that when leadership types are analyzed separately, both directly influence employee performance.

Originality/value
This study has four main contributions: to test the influence of the two leadership styles on employee performance and thus to help advance the theoretical understanding of leadership; to perform this test in the context of Brazilian startups; to equip professionals with more information about the effects of crucial leadership types on individual type of employee performance; and to expand knowledge for recruitment and managerial training in initial-stage companies.
The contingent roles of perceived budget fairness, budget goal commitment and vertical information sharing in driving work performance
Authors: Nguyen Nguyen Phong , Evangelista Felicitas , Kieu Tai Anh 
Published: April 2019

PurposeDrawing on equity theory, social exchange theory and goal setting theory, the purpose of this paper is to investigate the contingencies on the link between employees’ budgetary participation and their work performance. Specifically, this study addresses the research questions: whether vertical information sharing and budget goal commitment mediate the relationship between employees’ budgetary participation and their work performance; and whether employees’ perceived budget fairness can strengthen the positive effects of budgetary participation on vertical information sharing and budget goal commitment.Design/methodology/approachSurvey data were collected from a sample of 556 low to middle level managers of business organizations in Vietnam. The research model and its hypotheses were tested using PLS-SEM. The standardized root mean squared residual value of the composite model was employed to assess model fit. Common method bias was also checked using the marker-variable approach.FindingsThis study has two key findings: both vertical information sharing and budget goal commitment partially mediate the positive effects of budgetary participation on work performance; and both dimensions of perceived budget fairness (distributive and procedural) elevate the positive relationships of budgetary participation – vertical information sharing and budgetary participation – budget goal commitment.Practical implicationsThe findings could benefit businesses in Vietnam and similar market contexts. Specifically, top management needs to select a proper level of budgetary participation that can facilitate information sharing vertically within the organization and motivate their employees to be more committed to achieve budget goals. Besides, the top management also needs to ensure that their employees perceive the fairness in the budgeting process.Originality/valueThe study contributes a greater understanding as regards the mediating roles of vertical information sharing and budget goal commitment as well as the moderating role of perceived budget fairness on the relationship between employees’ participation in the budgetary process and their work performance, especially in the context of an emerging market – Vietnam. Overall, this study contributes to the management and accounting literature with insights concerning a more complex process explaining employees’ work performance and triggered by their budgetary participation.
A surface electromyography controlled steering assistance interface
Authors: Nacpil Edric John Cruz , Zheng Rencheng , Kaizuka Tsutomu , Nakano Kimihiko 
Published: April 2019

Purpose
Two-handed automobile steering at low vehicle speeds may lead to reduced steering ability at large steering wheel angles and shoulder injury at high steering wheel rates (SWRs). As a first step toward solving these problems, this study aims, firstly, to design a surface electromyography (sEMG) controlled steering assistance interface that enables hands-free steering wheel rotation and, secondly, to validate the effect of this rotation on path-following accuracy.

Design/methodology/approach
A total of 24 drivers used biceps brachii sEMG signals to control the steering assistance interface at a maximized SWR in three driving simulator scenarios: U-turn, 90º turn and 45º turn. For comparison, the scenarios were repeated with a slower SWR and a game steering wheel in place of the steering assistance interface. The path-following accuracy of the steering assistance interface would be validated if it was at least comparable to that of the game steering wheel.

Findings
Overall, the steering assistance interface with a maximized SWR was comparable to a game steering wheel. For the U-turn, 90º turn and 45º turn, the sEMG-based human–machine interface (HMI) had median lateral errors of 0.55, 0.3 and 0.2 m, respectively, whereas the game steering wheel, respectively, had median lateral errors of 0.7, 0.4 and 0.3 m. The higher accuracy of the sEMG-based HMI was statistically significant in the case of the U-turn.

Originality/value
Although production automobiles do not use sEMG-based HMIs, and few studies have proposed sEMG controlled steering, the results of the current study warrant further development of a sEMG-based HMI for an actual automobile.
Effects of the biophilic atmosphere on intention to visit: the affective states’ mediating role
Authors: Ortegón-Cortázar Leonardo , Royo-Vela Marcelo 
Published: April 2019

PurposeThis paper aims to analyze how a biophilic atmosphere inspired by nature influences customers’ affective states and intention to visit shopping centers, and to empirically test how affective states affect and mediate the relationship between the nature-based atmosphere and behavior or intention to visit.Design/methodology/approachFour hypotheses are examined empirically through a model of structural equations using control variables. A survey of 403 consumers distributed in 24 large shopping centers was used.FindingsThe findings indicate the influence of the biophilic atmosphere on affective states and the intention to visit. Also, it is shown that affective states mediate in this relationship and effect.Practical implicationsThe research suggests that shopping centers are potentially places to take advantage of people’s natural predisposition. Thus, they can combine biophilic architecture and atmosphere with other more traditional factors of attraction to increase the likelihood of visiting. A biophilic atmosphere can improve the attraction capacity within a highly competitive environment, where design and management of space is a topic of special value.Originality/valueBy incorporating the perception of the biophilic atmosphere in consumer evaluations when visiting shopping centers, this research has shown its influence on visiting intentions through affective states. The research proposes an alternative model that can increase and stimulate the attraction of demand and loyalty, as well as strengthening new paths in the field of retail and services marketing.
Determinants of return-on-equity in USA, German and Japanese manufacturing firms
Authors: Weidman Stephanie M. , McFarland Daniel J. , Meric Gulser , Meric Ilhan 
Published: April 2019

Purpose
DuPont financial analysis is generally used in micro-economic studies to compare an individual firm’s financial performance with industry averages. The purpose of this paper is to undertake a macro-economic cross-sectional analysis of the determinants of return-on-equity (ROE) in USA, German and Japanese manufacturing firms.

Design/methodology/approach
The authors use cross-sectional log-linear multivariate regression analysis to determine the elasticity of ROE to changes in net profit margin (NPM), total assets turnover (TAT) and equity multiplier (EQM) in USA, German and Japanese manufacturing firms. The authors obtain the data for the analysis from the COMPUSTAT Research Insight/Global Vintage database.

Findings
With data for all manufacturing firms, the authors find that the most important determinant of ROE is NPM in all three countries. The least important determinant of ROE is TAT in the USA and Germany, and EQM in Japan. Electronics is the most important manufacturing industry in all three countries, the authors also apply the analysis to data for the electronics manufacturing firms in the three countries. The authors find that an increase of 10 percent in NPM increases ROE by about 9.8 percent in Germany, by about 8.3 percent in the USA, and by about 6.9 percent in Japan. An increase of 10 percent in TAT increases ROE by about 2.2 percent in Germany and by about 1.5 percent in Japan. An increase of 10 percent in EQM increases ROE by about 1.9 percent in Germany and by about 1.5 percent in the USA.

Practical implications
The empirical findings of this study can provide useful insights for financial managers regarding the determinants of ROE they should focus on to achieve the greatest impact on ROE.

Originality/value
DuPont analysis is generally used as a micro-economic tool at the firm level. This study is a macro-economic application of the tool to study the cross-sectional determinants of ROE at the industry level.
Student investment groups: enhancing the liberal arts experience
Authors: Bergquist Brian D. , Keig Dawn L. , Wilkinson Timothy J. 
Published: April 2019

Purpose
Schools must not necessarily have a large amount of money or advanced finance curriculum for students to get the benefits of participating in a student-managed investment program. Any college or university with motivated students and faculty can have a successful program if they are willing to put forth the effort. The paper aims to discuss this issue.

Design/methodology/approach
The authors use a case study approach to examine specific characteristics of a successful student investment group implementation at a small liberal arts university in the Northwest USA.

Findings
Three student investment group implementation considerations are highlighted in this analysis: establishing an inclusive, interdisciplinary focus in a long-term club vs course format; utilizing all student-led training, governance and investment methodologies; and designing group processes with an emphasis on critical thinking and community outreach.

Practical implications
This case offers encouraging insights for how even a smaller college or university might successfully create and sustain a thriving successful student-led investment group with a relatively limited amount of funding and resources by leveraging liberal arts foundations.

Originality/value
An emphasis on how student-managed investment groups are tied to broader liberal arts foundations potentially helps schools of all sizes understand certain unique underlying value aspects for the students, the business programs and the broader university community.
Mergers and acquisitions: implications for acquirers’ market risk
Authors: Tanna Sailesh , Yousef Ibrahim 
Published: April 2019

PurposeThe purpose of this paper is to investigate the impact of mergers and acquisitions (M&As) on acquiring company systematic risk using a global sample of 34,221 completed deals that occurred between the years 1977 and 2012, covering 163 countries and 85 industries.Design/methodology/approachAcquirers’ systematic risk (beta) is calculated using the capital asset pricing model. The change in acquirers’ beta post-merger is obtained using event study and tested for mean differences across various sub-categories of deals. Cross-sectional regressions are then performed to test several hypotheses relating to the impact of diversification, method of payment, target status and prior experience on acquirers’ risk.FindingsFor the overall sample, the evidence suggests that acquirers’ beta tends to increase post-merger, but only in cases where their pre-merger risk is relatively low in relation to the risk of the market. The authors also show that cash payment deals for publicly listed targets contribute to reducing acquirers’ risk while stock payment increase risk. Diversification, whether global or across industry, has no significant impact on risk. On the other hand, for serial acquirers, the risk is increased significantly with more M&As.Originality/valueThis study contributes in a unique way by providing global evidence on acquirers’ systematic risk using a very large and diverse sample of M&A deals and investigating not only the impact of diversification on risk but also of other deal characteristics (e.g. method of payment, target status, acquirers’ prior experience) which have not been previously examined.
Doctoral student experiences in biological sciences laboratory rotations
Authors: Maher Michelle A. , Wofford Annie M. , Roksa Josipa , Feldon David F. 
Published: April 2019

Purpose
The purpose of this study is to explore the experience of selecting and engaging in biological sciences laboratory rotations from the perspective of doctoral students.

Design/methodology/approach
Within the socialization framework, this study uses a qualitative approach whereby 42 biological sciences students enrolled at highly selective US universities were interviewed in the first and second year of doctoral training about laboratory rotation experiences.

Findings
The study revealed how doctoral students used formal and informal information networks, explored research topics, struggled with funding concerns and learned about the social aspect of the laboratories in which they rotated.

Originality/value
While rotations are considered a signature pedagogy in the laboratory sciences, students’ experiences within them are understudied. This study offers new knowledge about what doctoral students experience while rotating that can be used to inform and improve rotation processes for both students and universities.
Different kinds of research shoppers, different cognitive-affective consequences
Authors: Viejo-Fernández Nuria , Sanzo-Pérez María José , Vázquez-Casielles Rodolfo 
Published: April 2019

Purpose
Customer journey is more omnichannel than ever. Currently, one of the most influential omnichannel behaviors is research shopping in its two predominant forms: webrooming and showrooming. The purpose of this study is to determine the possible moderating effect of each of these behaviors from a cognitive-affective perspective.

Design/methodology/approach
The proposed theoretical framework was applied to a sample of 636 mobile phone users.

Findings
The results indicated that research shopping moderated the intensity of the relationship between emotions and perceived value and between emotions and satisfaction. The analysis of the moderating effect of each concrete type of research shopping behavior indicated that negative emotions had a more intense negative effect on perceived value and satisfaction in the case of webrooming than in the case of showrooming.

Originality/value
This study focused on determining the possible moderating effect of research shopping vs one-stop shopping and webrooming vs showrooming on the intensity of the relationship between emotions, perceived value and satisfaction, considering determining factors of customer engagement to retailers (Han and Jeong, 2013). To achieve this objective, the authors performed a quantitative research in the Spanish market, choosing mobile phones as a reference product. The results will contribute to the current state of omnichannel retailing research by the analysis – through a cognitive-affective approach – of the consequences that research shopping and each of its two basic types (webrooming and showrooming) have on retailers.
