Abstract

Purpose

Research has found that the effects of directly experiencing mistreatment at work are consistently negative; however, results from studies examining employees' reactions to witnessing mistreatment are less consistent. This study focuses on nurses witnessing patient mistreatment in order to examine how third parties respond when witnessing patients mistreating co-workers. We argue that nurses high on other-orientation are less likely to experience emotion exhaustion in the face of witnessing patient mistreatment, whereas nurses high on self-concern are more likely to experience emotional exhaustion. We further argue that the indirect effect of witnessing patient mistreatment on job performance through emotional exhaustion is moderated by other-orientation and self-concern.

Design/methodology/approach

We used data collected at two time points, with six months apart, from 287 nurses working in a hospital. The study tests the hypotheses by using multiple regression analyses.

Findings

Emotional exhaustion mediated the relationships between witnessing patient mistreatment and two forms of job performance: patient care behaviors and counterproductive work behaviors. Furthermore, other-orientation moderated these indirect relationships such that the indirect relationships were weaker when other-orientation was high (vs. low). Self-concern did not moderate these relationships.

Practical implications

Service and care-oriented businesses may protect their employees from the risk of burnout by promoting prosocial orientation among their patient and customer-facing employees.

Originality/value

This study contributes to the literature by demonstrating the detrimental effects of witnessing patient mistreatment on nurses' performance. It also extends the current understanding of why and when witnessing patient mistreatment is related to performance by demonstrating the joint effects of witnessing patient mistreatment and an individual difference construct, other-orientation on employees' performance.

Abstract

Purpose

The purpose of this paper is to present a study of radial aircraft tire for safety assessment during various scenarios.

Design/methodology/approach

A detailed finite element (FE) model of aircraft tire was established based on the actual geometry of the target tire for numerical simulations. As the major component of this tire, rubber material usually presents a complicated mechanical behavior. To obtain the reliable hyperelastic properties of rubber, a series of material tests have been processed. Moreover, in order to validate the proposed model, the simulations results of inflation and static load scenarios were compared with the experimental results. Both of the control volume and corpuscular particle method methods were used in the numerical simulations of aircraft tire.

Findings

The comparisons of the two methods exhibit close agreement with the experimental results. To assess the safety of aircraft tire during the landing scenario, the dynamic simulations were processed with different landing weights and vertical landing speeds. According to the relevant airworthiness regulations and technical documents, the tire pressure, deflection and load have been chosen as the safety criteria. Subsequently, the analysis, results and comments have been discussed in detail.

Originality/value

The validated FE model proposed in present study can be effectively used in tire modeling in static and dynamic problems, and also in the design process of aircraft tire.

Abstract

Purpose

Blade tip clearance has always been a concern for the gas turbine design and control. The numerical analysis of tip clearance is based on the turbine components displacement. The purpose of this paper is to investigate the thermal and mechanical effects on a real cooling blade rather than the simplified model.

Design/methodology/approach

The coupled fluid-solid method is used. The thermal analysis involves solid and fluid domains. The distributions of blade temperature, stress and displacement have been calculated numerically under real turbine operating conditions.

Findings

Temperature contour can provide a reference for stress analysis. The results show that temperature gradient is the main source of solid stress and radial displacement. Compared with thermal or mechanical effect, there is a great change of stress magnitude for the thermomechanical effect. Large stress gradients are found between the leading and trailing edge of turbine cooling blade. Also, the blade radial displacement is mainly attributed to the thermal load rather than the centrifugal force. The analysis of the practical three-dimensional model has achieved the more precise results.

Originality/value

It is significant for clearance design and life prediction.

Abstract

The extant literature provides much-needed support to understand marketing accountability and how marketing actions are related to financial performance (FP). However, we have limited understanding of the relationships between marketing actions and firms' social performance (SP) and environmental performance (EP). Understanding these links is critical to enhancing sustainable FP, SP, and EP. Moreover, the literature provides limited understanding of the measures by which SP and EP may be operationalized, or the data necessary to reach a conclusion. This study bridges these gaps by extensively reviewing the extant literature to offer a set of measures and data sources to operationalize SP and EP, and empirically show their relationships with marketing actions. We find that greenhouse gas (GHG) emission, environmental disclosure score, waste reduction, energy consumption, and recycling are prominent measures of EP, and that social disclosure score, philanthropy or community spending, and diversity of gender and race are prominent measures of SP. The KLD, ASSET4, and Bloomberg are prominent sources of data that can be used to operationalize SP, to which CDP may be added for EP. We also show that marketing actions positively affect EP and SP. This study contributes to the extant literature on SP and EP by identifying measures and data sources and linking marketing actions to both performance types. It contributes to policy development by identifying the importance of EP and SP and how marketing actions can help achieve such performance.

This study examines whether and how government fiscal pressure influences corporate charitable giving (CCG).

Abstract

Purpose

This study examines whether and how government fiscal pressure influences corporate charitable giving (CCG).

Design/methodology/approach

The authors exploit sub-national tax revenue sharing changes as exogenous variations to government’s fiscal pressure at the city level and then construct a quasi difference-in-differences (DiD) model to conduct the analysis based on a sample that consists of 14,168 firm-year observations in China during the period of 2003 to 2012.

Findings

The authors found that firms increase charitable donations when local governments face higher fiscal pressure. Such effects are more pronounced for firms that have stronger demand for political connectedness in the sample period. Furthermore, this study’s findings suggest that the timing strategy of donating helps firms to lower the effective tax rate and to build stronger political connections. In addition, donating firms outperform non-donating firms in terms of bank loan access and market reputation.

Originality/value

The authors contribute to at least three lines of literature: first, extend the understanding of timing strategies of corporate charitable behaviors; second, contribute to the literature studying the “crowd out” effect between government-provided charitable funds and private donations; finally, contribute to the emerging literature exploring the financial interests associated with corporate donation strategy (Claessens et al., 2008; Cull et al., 2015).

Abstract

Library buildings are routinely reimagined, remodeled, or built new to meet the changing needs of their community. The move from collection-centric to user-centric service models has generated numerous writings about the library as place and space. The one concept lacking in the scholarly discourse is the changing roles of librarians to meet the needs of these new spaces and places. How do librarians fit in the new equation? When addressing the professional identity of librarians, which aspect of their work will need to evolve and which will need to be let go? A critical facet of sustaining services in new spaces is the need to develop the sustainable librarian – to remove the stigma of the librarian as “jack of all trades, master of none.” In order to realize this new mindset of mastering our domain we need to begin reimagining our work. Some ways, this can be accomplished by writing increased flexibility into position descriptions and creating organizational structures to better support librarians within the new spaces. With these new developments to our professional identities, librarians may learn to employ entrepreneurial skills in order to continuously anticipate services and develop skill sets to aid the library’s ability to fulfill its purpose. The authors provide a literature review to discuss the changing role of the academic librarian to meet the evolution of the library building and services. We will provide an example through findings and practices of Grand Valley State University and how it reimagined roles in the early 2000s and continues to reimagine roles in a new building and a renovated branch library. The change of spaces and places in academic libraries to accommodate user needs and perceptions has impacted how academic librarians work in these spaces and places. Library administrators need to rethink workflows, and organizational charts by examining flexible workloads, cross-training initiatives, professional development around new skills, and the letting go of obsolete practices.

Originality/value – in this chapter, the authors will discuss how library leaders are charged with translating the new roles of their librarians to meet the needs of their community in these new spaces and how library leaders may look beyond the literature of the profession for ways to facilitate change.

Abstract

In recent years, many new and interesting business models for Internet-based selling have emerged with the advent of electronic commerce, one of which is the Internet-based group-buying. Since group-buying can be quickly built and removed, and the consumers can pay a lower price for the product through it, the group-buying can be a new online promotion form. In this chapter we build up a two-period pricing model for a supply chain when a supply chain member utilizes group-buying program to promote its products. In detail, we consider a supply chain consisting of a supplier and a retailer, where the supplier or retailer may launch a group-buying program to promote the products via a group-buying web site in the promotion period (i.e., the first period), as well as the supplier may sell its products through the retailer traditionally in both periods. Utilizing game theory, we derive the equilibrium decisions of the two supply chain members in three different scenarios, that is, (i) there is no group-buying program, (ii) the supplier launches a group-buying program, and (iii) the retailer launches a group-buying program. Analysis of the equilibrium decisions illustrates the following results: (i) both, the supplier and the retailer, will set low prices in the promotion period and high prices in the regular period; (ii) this trend will be enhanced when a group-buying program occurs, especially when such program is launched by the supplier; (iii) while the retailer can always benefit from a group-buying program, the supplier’s profit may be reduced under certain conditions; and (iv) in spite of the fact that the supplier’s profit may be damaged by the group-buying program, when the two supply chain members decide to launch a group-buying program, the unique equilibrium is that the supplier will launch such a program.
