Abstract
Purpose
The COVID-19 pandemic has burdened the health-care system and exposed nurses to immense stress. This study therefore aims to investigate nurses’ mental well-being who are working with COVID-19-positive patients. Burnout leads to decreased productivity and manifests as emotional exhaustion, depersonalisation (cynicism) and low personal accomplishment (professional efficacy). Authentic leadership is built on a humanistic value system, which is the core value of nurses and other health-care professionals. This study therefore used authentic leadership as the independent variable.
Design/methodology/approach
A cross-sectional quantitative research method was adopted by distributing validated online questionnaires to 1,334 nurses in a private pathology laboratory and 241 questionnaires were analysed with 93.4% female respondents. Multiple linear regression model testing was conducted.
Findings
Multiple regression analyses showed statistically significant negative correlations between authentic leadership and emotional exhaustion, cynicism, job stress and job-stress-related presenteeism, and a positive correlation between authentic leadership and professional efficacy.
Practical implications
This study provides empirical data to encourage organisations to focus on developing authentic leaders to decrease nurses’ burnout, job stress and presenteeism. The health-care sector should strive to create an environment where nurses are valued and their talent is recognised to increase employee engagement and commitment.
Originality/value
There were two contributions in this study: first, to determine whether there is a relationship between authentic leadership job stress and job-stress-related presenteeism. Second, to determine whether there is a relationship between authentic leadership and the three sub-constructs of burnout.

Abstract
Purpose
The purpose of this paper is to investigate the relationship between complexity leadership and contextual ambidexterity as well as the mediating effect of organisational innovation climate in this link. This study is an answer to a call on which leadership approach and mediating factors can meet today’s seemingly contradictory challenges of efficiently managing business demands, while simultaneously searching for new opportunities.
Design/methodology/approach
The researchers analysed 1,204 usable survey responses from employees of South African organisations. Analysis was in the form of structural equation modelling. Mediation analysis was carried out on estimates of the indirect effect.
Findings
Results show that complexity leadership was a strong predictor of innovation climate; in turn, innovation climate positively impacts exploratory innovation by 64 per cent; complexity leadership and innovation climate positively affect exploitation by 57 per cent. The innovation climate plays a total mediator role between complexity leadership and exploratory innovation and a partial effect on exploitation.
Practical implications
This study gives human resource management (HRM) insight into strategically directing leadership recruitment and development towards creating an organisational climate to enhance ambidexterity. HRM must conduct regular climate surveys to ascertain whether current leadership is creating an environment that enables exploratory and exploitative innovation.
Originality/value
The authors’ contribution includes a theoretical contribution to the emerging field of complexity leadership by offering conceptual as well as empirical evidence of its role in ambidexterity. This study extends previous research in highlighting organisational climate’s mediating role of being open to new ideas to enable exploratory innovation.

Abstract
Synopsis
Rick Jamison, as Project Manager for the highly profitable Mega-Yacht division of Thorsby-Wando Marine Refit, Inc., has been assigned the task of revamping the supplier evaluation and selection tool used by the company in view of the evolution of the business from a small boat storage and repair facility into a full-service large boat and mega-yacht repair and refit facility. Rick gleans ideas from a colleague at another facility in preparation for re-crafting the current supplier evaluation tool. Rick becomes acquainted with how the Delphi method could be used to achieve consensus among members of the buying center to arrive at key factors and their proportionate weights for use in the supplier evaluation tool.
Research methodology
The case is based upon interviews with the company that is represented by Thorsby-Wando Marine Refit, Inc.
Relevant courses and levels
This case is targeted primarily at undergraduate students in purchasing, materials management and supply chain management courses. The case works best when it is employed in connection with a discussion of the major methods for evaluating vendors.

Abstract
This short case could be handed out at the end of class discussion on “J&L Railroad” [UVA-F-1053] in preparation for the following class, or if students are more experienced with hedging and option pricing, the instructor may choose to cover both cases in a single class period. It is the companion case to “J&L Railroad” [UVA-F-1053], and presents more technical issues regarding the hedging problem by requiring students to understand option-pricing principles. The board likes the CFO's hedging recommendations, but it wants a more careful analysis of the bank's prices for its risk-management products: the caps and floors. Besides demanding an understanding of option pricing, this case puts particular emphasis on the calculation and use of implied volatility.

Abstract
Purpose
When appropriately implemented, excellence models such as the Shingo operational excellence model (SOEM), Baldrige performance excellence model and EFQM business excellence model aid enterprise quests for sustained superior results across varied dimensions. Evidence supporting this statement abounds in the literature and in practice. The models, however, tend to be driven by experience, rather than grounded in theory. The purpose of this paper is to explore theoretical underpinnings for such models, with the SOEM used for illustrative purposes.
Design/methodology/approach
Management theory, systems theory and excellence modeling are integrated to yield a complex management systems based operational excellence model. Correspondence of this model with the SOEM is explored. Key elements considered include contextual factors external to the enterprise, diverse stakeholders, mediating forces, enterprise culture and representative enterprise processes.
Findings
Understanding the theoretical underpinnings of excellence models—their elements and the interactions and synergies of these elements—enables more sure adaptation of such models to specific enterprise contexts, and more sure course corrections whenever corrections are needed.
Originality/value
Many excellence models exist, their usefulness largely validated by anecdotal or empirical evidence. Such validation is important, but falls short of theoretically grounding these models. The approach taken herein serves to unify theory, empirical evidence and anecdotes, thus placing excellence models on more solid ground.

This paper aims at discussing the impact of quality electricity on household income (HI) in rural areas with complementarities and intermediary resources context.
Abstract
Purpose
This paper aims at discussing the impact of quality electricity on household income (HI) in rural areas with complementarities and intermediary resources context.
Design/methodology/approach
Partial least square-structural equation modelling (PLS-SEM) was used to estimate complex variables of quality electricity (QEC), development assets (DEA) and individual motivation (IMO) on rural HI. Age, education and gender were treated as moderators of antecedents for HI whilst household strength (HS) was treated as a mediator.
Findings
The findings show that QEC is an important predictor for HI in rural areas. In similar vein, land, social network, financial and physical resources cannot be undermined in bringing HI on stage. Moreover, IMO is a best complementary for electricity to bear impact on income. In fact, income cannot be equated with one factor; hence, moderating roles of education and gender should be considered.
Research limitations/implications
The results are limited to QEC, IMO and DEA as key resources which are associated with HI.
Practical implications
The findings should be twinned with rural development policy. There must be a multi-dimensional approach in diversifying development resources to the rural people for aggregated benefits.
Social implications
The rural communities remain in dire need of electricity which is a precious resource for income generation. Electricity works better with other resources.
Originality/value
Previous scholars have inferred HI in relation to electricity. Income is a function of many resources. This study inculcated complementaries and intermediaries along QEC. Unique PLS-SEM was used in rethinking some of the rethinking of QEC–income relationships.

Abstract
In September 2015, VW had admitted to United States regulators that it had deliberately installed “defeat devices” in many of its diesel cars, which enabled the cars to cheat on federal and state emissions tests, making them able to pass the tests and hit ambitious mileage and performance targets while actually emitting up to 40 times more hazardous gases into the atmosphere than legally allowed. The discovery had prompted the U.S. Environmental Protection Agency (EPA) to halt final certification of VW’s 2016 diesel models, and VW itself had halted sales of its 2015 models. As fallout from the defeat devices developed, VW posted its first quarterly loss in more than 15 years, and its stock plummeted. Top executives were replaced, and VW abandoned its goal of becoming the world’s largest automaker. Stakeholders around the world had been asking since the scandal broke: “How could this have happened at Volkswagen?”
