Employees’ burnout and emotional intelligence as mediator and moderator in the negative spiral of incivility
Authors: Kim Haemi , Qu Hailin 
Published: April 2019

PurposeThis paper aims to study how the negative spiral of incivility from customers to employees happens by measuring the mediating effect of employees’ burnout. Moreover, it investigates how to mitigate the detrimental influences of customer incivility by assessing the moderating effect of employees’ emotional intelligence.Design/methodology/approachA cross-sectional questionnaire survey using MTurk was conducted, targeting full-service restaurant employees. Descriptive statistic, confirmatory factor analysis, structural equation modeling and hierarchical multiple regression analysis were applied.FindingsThe results presented that there is a direct relationship between customer incivility and employee incivility toward customers and coworkers. Additionally, employees’ burnout significantly mediates the relationship between customer incivility and employee incivility. Moreover, it presented the significant moderating effect of employees’ emotional intelligence on the relationship between customer incivility and employee incivility.Research limitations/implicationsExperiences of customer incivility during a service encounter directly trigger employee incivility. Moreover, customer incivility indirectly leads to employee incivility by increasing employees’ burnout. In addition, employees’ emotional intelligence mitigates a negative spiral of incivility from customers to employees. However, this study has limitations that provide suggestions for future research.Originality/valueThis research shows how customer incivility causes employee incivility in the workplace. It also shows a significant moderating role of employees’ emotional intelligence to mitigate the influence of customer incivility on employee incivility.
Witness of Things

Published: April 2019

Purpose
The purpose of this paper is to develop a model for autonomous cars to establish trusted parties by combining distributed ledgers and self-driving cars in the traffic to provide single version of the truth and thus build public trust.

Design/methodology/approach
The model, which the authors call Witness of Things, is based on keeping decision logs of autonomous vehicles in distributed ledgers through the use of vehicular networks and vehicle-to-vehicle/vehicle-to-infrastructure (or vice versa) communications. The model provides a single version of the truth and thus helps enable the autonomous vehicle industry, related organizations and governmental institutions to discover the true causes of road accidents and their consequences in investigations.

Findings
In this paper, the authors explored one of the potential effects of blockchain protocol on autonomous vehicles. The framework provides a solution for operating autonomous cars in an untrusted environment without needing a central authority. The model can also be generalized and applied to other intelligent unmanned systems.

Originality/value
This study proposes a blockchain protocol-based record-keeping model for autonomous cars to establish trusted parties in the traffic and protect single version of the truth.
Switching from hotels to peer-to-peer accommodation: an empirical study
Authors: Yan Ruihe , Zhang Kem Z.K. , Yu Yugang 
Published: April 2019

Purpose
Peer-to-peer (P2P) accommodation has become increasingly popular in recent years, and hotels are facing unprecedented impacts. Attracting new consumers and retaining existing ones are critical to the success of P2P accommodation and hotels. The purpose of this paper is to examine three categories of antecedents for hotels consumers’ switching intention: push (i.e. satiation), pull (i.e. perceived value) and mooring (i.e. optimal stimulation level) factors using push–pull–mooring (PPM) model.

Design/methodology/approach
Airbnb was chosen as the research context. An online survey was conducted to examine the proposed research model and hypotheses. A total of 292 valid data were collected from Airbnb users through a survey.

Findings
The findings show that the three categories of factors have positive and significant effects on switching intention. Additionally, the mooring factor has a significant moderating effect on the relationship between pull factors and switching intention. Furthermore, the mooring factor affects both pull and push factors.

Originality/value
First, this is one of the early studies to pay attention to switching intention from hotels to P2P accommodation. Second, to provide a comprehensive understanding of consumers’ switching intention, the authors use PPM model to establish the research framework. This research improves the understanding of consumer’s switching intention by identifying the push and pull factors based on the differences between hotels and P2P accommodation in accordance with optimal stimulation level theory and consumer value theory.
Contribution of policy change on maize varietal development and yields in Kenya
Authors: Nagarajan Latha , Naseem Anwar , Pray Carl 
Published: April 2019

PurposeSince the start of seed and other market reforms in the 1990s, the annual number of improved varietal releases for maize in Kenya has increased substantially. Prior to the reforms, private firms were restricted in introducing new varieties, could not protect their intellectual property and farmers had to rely exclusively on improved seeds developed and marketed by the public sector. Reforms have resulted in not only private firms entering the market and releasing improved varieties, but also an increase in varietal releases by the public sector. The purpose of this paper is to review some of the key policy reforms related to maize in Kenya, and their impacts on varietal development and yields.Design/methodology/approachThe authors estimate a yield model that relates national maize yields to a number of input policy variables. The authors employ a two-stage least square regression, as one of the explanatory variables – the number of varietal releases – is likely endogenous with yield. The authors use policy variables such as public R&D, the number of plant breeder’s rights issued, and the years since private varieties have been introduced as instrument variables to estimate their influence new varietal releases directly, and then new varieties, inputs and other policies to measure their impact on yields.FindingsThe results show that policy changes such as the introduction of intellectual property rights had an important impact on the number of improved maize varieties released. However, the outcomes of the policy change such as the number of varieties and the share of area under improved varieties has no impact on increasing maize yields. The authors argue that this is because farmers continue to use older improved varieties because of the dominance of a parastatal in the maize, seed market and that newer improved varieties may not have the assumed yield advantage. Future policy and programs should be directed toward increasing the adoption of improved varieties rather than simply releasing them.Originality/valueThis paper provides evidence that while policy change may lead to new varietal development and release, its aggregate productivity impacts may be limited without additional reforms and intervention.
Puritan peers or egoistic entrepreneurs? Moral decay in lateral exchange markets
Authors: Perren Rebeca , Stewart Kristin , Satornino Cinthia B. 
Published: April 2019

PurposeThe purpose of this study is to examine the impact of LEM participation on moral identity. Lateral exchange markets (LEMs) enable ordinary people to monetize idle personal resources such as cars, homes, gadgets and skills. Despite its champions portraying actors in these exchange as moral citizens of society, recent findings suggest that egoistic motives drive participation. A salient moral identity motivates behaviors that show social sensitivity to others and enable cooperative actions. Given that platform-providing firms rely on users’ cooperative behaviors to facilitate lateral exchange, understanding factors that affect moral identity can have important implications for the success of such business models.Design/methodology/approachIn this research, the authors move away from the ideological discourse behind actors’ motivations, to provide a pragmatic explanation of how participation erodes moral identity. The authors apply a social cognitive framework to examine how the environment in LEMs impacts behaviors and personal factors in a recursive fashion.FindingsAcross two studies, findings reveal that prolonged participation in lateral exchange diminishes the centrality of moral identity to the working self-concept. Moreover, the results show that keeping puritan peers moral has positive business outcomes. This research also discerns a boundary condition that determines when peers remain consistent with their moral compasses. Specifically, when engagement is perceived as effortful, the behavior becomes an informative input in the inference of one’s moral disposition reinforcing moral identity.Originality/valueMarketers can use this research to design business models in ways that mitigate the decay of moral identity.

The interplay between zinc and iron homeostasis in Aspergillus fumigatus under zinc‐replete conditions relies on the iron‐mediated regulation of alternative transcription units of zafA and the basal amount of the ZafA zinc‐responsiveness transcription factor
Authors: Vicentefranqueira Rocío , Leal Fernando , Marín Laura , Sánchez Clara Inés , Calera José Antonio 
Published: April 2019

Summary
Aspergillus fumigatus is a saprophyte fungus that typically grows on organic decaying matter but can also parasitize immunosuppressed hosts. This is explained, in part, by its great ability to take up Zn2+ ions from living tissues, which is induced by the ZafA transcription factor. This study shows that the ZafA‐mediated regulation of fungal growth is also influenced by iron availability and that A. fumigatus is well adapted to grow in zinc‐limiting and zinc‐replete media with Zn:Fe ratios lower in the former than in the latter. Accordingly, this indicates that iron availability appears to be more critical for fungal growth in zinc‐replete than in zinc‐limiting environments. Interestingly, the cross‐regulation of zinc/iron homeostasis under zinc‐replete conditions relies on an unprecedented iron‐mediated regulation of different zafA transcription units that, along with a limited transcript translation, allows synthesizing the right basal amount of ZafA dependent on iron availability. We posit that this regulatory strategy has evolved in fungi as a mechanism to adjust zinc intake to iron availability under zinc‐replete conditions. Thus, fungal growth is enhanced in zinc‐ and iron‐replete media but restricted by reducing zinc intake under iron starvation to prevent the noxious side effects of an intracellular zinc excess during iron deficiency.

Published: April 2019

AbstractPlanting tree species that are well adapted to local ecological conditions guarantees the success and sustainability of forest restoration. The aim of this study was to investigate the acclimation of two varieties ofPinus pinaster(var.renouifrom Tunisia and var.maghrebianafrom Morocco), to the ecological conditions of the Kroumirie Mountains in northwest of Tunisia. Tree growth performance (diameter at 1.30 m [DBH], ring widths and total height) and climate–growth responses over the period 1970–2013 were evaluated for two varieties. The trees used in this study were from pine variety and provenance trials growing in common garden in Souiniet (21 trees per variety). Significant difference in height growth rate, DBH and ring widths was found between the two varieties. The Maghrebiana variety had the highest survival and mean radial growth rates. The mean sensitivity to climate was the same in two varieties. A significant negative correlation between May precipitation and radial growth was found for var.maghrebiana. Both varieties showed a significant negative correlation between May and June temperatures and radial growth. January–February temperatures had a positive influence on ring width. The Maghrebiana variety appears well acclimatised so it is expected to ensure more successful restoration of Kroumirie Mountains.
Chronic lymphocytic leukaemia: the role of T cells in a B cell disease
Authors: Man Stephen , Henley Peter 
Published: April 2019

SummaryChronic lymphocytic leukaemia (CLL) has long been thought to be an immunosuppressive disease and abnormalities in T‐cell subset distribution and function have been observed in many studies. However, the role of T cells (if any) in disease progression remains unclear and has not been directly studied. This has changed with the advent of new therapies, such as chimeric antigen receptor‐T cells, which actively use retargeted patient‐derived T cells as “living drugs” for CLL. However complete responses are relatively low (~26%) and recent studies have suggested the differentiation status of patient T cells before therapy may influence efficacy. Non‐chemotherapeutic drugs, such as idelalisib and ibrutinib, also have an impact on T cell populations in CLL patients. This review will highlight what is known about T cells in CLL during disease progression and after treatment, and discuss the prospects of using T cells as predictive biomarkers for immune status and response to therapy.

Published: April 2019

BackgroundRight heart enlargement is common in the athletes' heart phenotype; however, few data exist regarding interpretation of normal athletic adaptation during Preparticipation Cardiac Screening (PCS) of Rugby Football League (RFL) athletes. Echocardiography is utilized during PCS and thus the primary aim of this study was to establish the normal right ventricular (RV) phenotype in elite RFL athletes using standard 2‐D echocardiography and myocardial mechanics. The secondary aim was to describe right atrial (RA) structure and function using 2‐D echocardiography.Methods139 male RFL athletes underwent echocardiographic evaluation of the right heart including RV strain (ɛ) and strain rate (SR) imaging using speckle tracking echocardiography (STE). Nonathletic males were used for comparison and allometric scaling was applied for conventional echocardiographic parameters.ResultsScaled RV dimensions were larger in athletes (P < 0.05) with the exception of the mid‐cavity. No differences (P > 0.05) in RV fractional area change (FAC) and RV longitudinal ɛ were observed between groups. Tissue Doppler imaging (TDI)‐indexed parameters and global strain rate (SR) were lower (P < 0.05) in athletes with HR and weight found to have co‐variance with SR. The RA was larger in athletes (P < 0.001) with no functional difference (P > 0.05) observed by volume assessment.ConclusionsReduction in SR and indexed TDI are partly associated with lower HR and increased body mass and are likely to represent normal physiological adaptation in RFL athletes. RA enlargement appears proportional to RV enlargement. These data may aid interpretation of normal athletic adaptation during PCS of RFL athletes.
Adults of the cerambycid beetleMegacyllene caryaeuse both olfactory and visual information to locate mates
Authors: Johnson Todd D. , Hanson Elizabeth , Yu Allen 
Published: April 2019

AbstractMany species of beetles in the family Cerambycidae use volatile pheromones to facilitate the location of mates. Visual cues may also influence the location of mates, as the adults of many species of cerambycids are often brightly patterned and diurnal. Theory predicts that combining signals or cues of different modalities (e.g., chemical, visual) to transmit information will increase the likelihood of an organism responding to this information, compared to when the signal or cue is presented alone. Here, we test the hypothesis that attraction of adults of the cerambycid beetleMegacyllene caryae(Gahan) (Coleoptera: Cerambycidae, Clytini) to their pheromones will be increased when visual cues are present. Consistent with that hypothesis, the number of beetles caught by traps baited with pheromones was increased 3.4‐fold when a dead adult beetle of that species was attached to the trap, relative to those with just pheromone alone. Capture ofM. caryaein our study was also influenced by the position of traps within forest stands, with traps at 100 m within stands catching 2.5× as many beetles as traps at the forest edge. These findings suggest that vision and visual cues play an important role in the location of mates by cerambycid beetles and warrant further research. Also, the inclusion of visual cues on traps may enhance the efficacy of trapping cerambycid beetles, such as the detection of species that are non‐native and potentially invasive, or when monitoring species that are native and of conservation concern.
Multifield modelling and failure prediction of cellular cores produced by selective laser melting
Authors: Lampeas George , Diamantakos Ioannis , Ptochos Evaggelos 
Published: April 2019

AbstractA multifield simulation approach of cellular cores produced by additive manufacturing is presented. The analysis is aiming to derive the relation between the manufacturing process parameters and the resulting material failure behaviour. To this purpose, the selective laser melting manufacturing process is initially thermo‐mechanically simulated, followed by the mechanical analysis of the nonlinear core behaviour. The methodology is demonstrated in the case of open‐lattice body‐centred‐cubic (BCC) cellular cores.
Simulation of cracking behaviours in interlayered rocks with flaws subjected to tension using a phase‐field method
Authors: Zhou Xiaoping , Jia Zhiming , Berto Filippo 
Published: April 2019

AbstractA phase‐field method (PFM) is used to investigate cracking behaviours, including crack initiation and propagation, in interlayered rocks with preexisting flaws subjected to tension. An example with a bi‐material plate with a centre flaw is used to validate the PFM. Then, numerical simulations of cracking behaviours in interlayered rocks with a single flaw and a cross‐flaw are carried out using PFM. Moreover, the load‐displacement responses are numerically investigated. The PFM numerical results show that the crack propagation trajectories and peak loads of rock specimens depend on the preexisting flaw configuration and the mechanical properties of the interlayers.

AbstractObjectiveTo examine the effectiveness of tailored xerostomia and nutritional 6‐month interventions on xerostomia among home care clients aged 75 years or over who were malnourished or at risk of malnutrition.BackgroundA subjective feeling of dry mouth (xerostomia) is common among older adults and affects their quality of life, nutrition and oral health. Medical conditions, polypharmacy, dehydration and malnutrition are often underlying causes of xerostomia.Materials and MethodsThe data are based on the NutOrMed study with a dietary intervention group of 119 patients and control group of 97 patients. In‐home interviews were carried out by home care nurses, nutritionists, dental hygienists and pharmacists and tailored interventions by nutritionist and dental hygienists. Xerostomia intervention included individual counselling on dry mouth care and was applied to all those suffering occasionally or continuously from xerostomia (57%, n = 66) in the intervention group. Nutritional intervention was applied to all participants in the intervention group, and it included instructions on increasing the number of meals, energy, protein intake and liquid intake.ResultsAmong participants who received both interventions, xerostomia decreased by 30% and malnutrition or risk of malnutrition decreased by 61%. The interventions were highly significant (OR 0.1, 95% CI: 0.06; 0.2) in reducing xerostomia.ConclusionsHome care clients suffering from xerostomia profited significantly from tailored xerostomia and dietary interventions. Evaluation and treatment of xerostomia are important among older persons who are malnourished or at risk of malnutrition as a part of a comprehensive health intervention to improve their nutrition and oral health.
Exploring South African consumers’ attitudes towards game meat—Utilizing a multi‐attribute attitude model
Authors: Wassenaar Anjolize , Kempen Elizabeth , van Eeden Tertia 
Published: April 2019

AbstractThe study explored the use of a multi‐attribute approach, Fishbein’s attitude‐towards‐the‐object model, in finding the differences between the attitudes of consumers and nonconsumers of game meat among South African respondents towards the following attributes of game meat: sensory characteristics; health benefits; game meat production ethics; animal welfare; safety for human consumption; availability; and price. This quantitative study determined the attitudes of 1,096 consumers and 310 nonconsumers of game meat with an online survey. Based on attitudes towards individual attributes, as determined by Fishbein’s attitude‐towards‐the‐object model, respondents classified some product attributes as important in their decision to consume, or not to consume, game meat. Respondents indicated that the availability, sensory characteristics, game meat production ethics and health benefits are considered to be important in their decision to consume game meat.
