Influence of meaningfulness of work and leadership characteristics on customer-directed counterproductive work behavior resulting from customer mistreatment.

This study explored the impact of customer mistreatment on counterproductive work behavior (CWB) and the moderating role of supervisor responses (self-sacrificial and self-serving leadership) to clarify why customer-directed CWB occurs and how it can be reduced. A sample of 392 customer-facing employees in the USA completed measures assessing the meaningfulness of work and self-sacrificial and self-serving leadership experiences. The meaningfulness of work moderated the relationship between customer mistreatment and employee anger, and a three-way interaction was found between employee anger and self-sacrificial and self-serving leadership on customer-directed CWB. Implications for managing customer mistreatment and fostering meaningful work to promote employee well-being are discussed.

Thermal performance of dual flow slotted fin mini channel heat sink using Al2O3-H2O and TiO2-H2O: a numerical and experimental approach.

To overcome the extensive heat generation inside the microprocessors nanofluids have gained importance because of their better thermophysical properties as compared with air and water. This work proposes a two-pronged strategy for thermal performance enhancement of mini channel heat sinks. Firstly, a novel dual flow slotted fin mini channel heat sink flow configuration is proposed. Secondly, a detailed numerical investigation is performed to assess heat transfer enhancement property of Al2O3-H2O and TiO2-H2O nanofluids. Considering the first step, fin spacing, number of slots, slot thickness and slot angle are investigated in detail yielding to the selection of best structural parameters. Two slots per fin of 0.5 mm thickness at an angle of 45° is selected because it provides better thermal performance as compared with water. Further, numerical assessment of nano fluid behavior was carried out at volumetric concentrations of 0.005% and 0.01%. For the case of novel dual flow slotted fin mini channel heat sink, maximum numerical and experimental advantages in all targeted system properties is observed for Al2O3-H2O nano fluid at volumetric concentration of 0.01%, as compared with water. Al2O3-H2O nano fluid provides better thermal performance both numerically and experimentally as compared with TiO2-H2O nanofluids. Increment in the pressure drop is noted with increasing volumetric concentrations.

Cost of Serving Others: A Moderated Mediation Model of OCB, Ego Depletion, and Service Sabotage.

Taking support from ego-depletion theory, this study examines ego depletion as a mechanism that explains how employees' organizational citizenship behavior (OCB) leads to antagonistic consequences, i.e., service sabotage. Employees' positive psychological capital (PsyCap) is considered a moderator. PROCESS macro was used to test all the hypotheses using time-lagged, dyadic data collected from 420 employees and their 112 their supervisors associated with the service industry in China. This study finds that employees' exhibition of OCB is positively linked to ego depletion, which in turn drives service sabotage behavior. Furthermore, employees' PsyCap weakens the effect of OCB on employees' ego depletion. This study highlights the dark side of OCB, the mechanism through which it causes adverse effects, and the moderating effect of PsyCap. It also provides insights to the organizations for managing service sector employees to effectively interact with customers.

"Crisis management in the hospitality sector SMEs in Pakistan during COVID-19″.

The COVID-19 pandemic has delivered one of the worst economic shocks in modern history and the hospitality sector has been severely affected. Since small businesses from the hospitality sector are known to be relatively more susceptible to the economic complications arising from a crisis, we explore the underlying factors and management practices that influence their continuity of operations as they continue to struggle with the on-going COVID-19 crisis in Pakistan. Using a phenomenological approach, in-depth interviews were conducted to comprehend the experiences of owners-managers. The findings show that government support, cordial relationships with stakeholders, self-determination of entrepreneurs and formal planning are the most crucial factors that shaped the immediate adjustments of operational activities in response to COVID-19. These resilient practices are hygiene concerns, increased promotion through social media, innovative marketing practices (e.g., revised offerings), operational cost-cutting and employee training to comply with changing standard operating procedures from the government and industry. The practical and theoretical implications are also discussed.

I Will Hurt You for This, When and How Subordinates Take Revenge From Abusive Supervisors: A Perspective of Displaced Revenge.

Abusive supervision, defined as subordinates' perception of the extent to which supervisors engage in the sustained display of hostile verbal and non-verbal behaviors, excluding physical contact, is associated with various negative outcomes. This has made it easy for researchers to overlook the possibility that some supervisors regret their bad behavior and express remorse for their actions. Hence, we know little about how subordinates react to the perception that their supervisor is remorseful and how this perception affects the outcomes of supervisors' undesired behavior. Specifically, drawing on the social exchange theory (SET) and displace revenge literature, this study explains how abusive supervision leads to victims' service sabotage behavior. In addition, this study also investigates how perceived supervisors' remorse (PSR) mitigates the adverse effects of abusive supervision. Based on time-lagged, dyadic data (63 supervisors, 212 subordinates) from Chinese individuals, this study found support for all the proposed relationships, i.e., abusive supervision leads to service sabotage through the mediating effect of revenge desire. The findings also conclude that PSR lessens the detrimental effects of abusive supervision on victims' behavior with their customers. Finally, this research contributes to service sabotage literature by highlighting the possibility where abusive supervisors cause service sabotage behavior among victims. This study also shows the importance of PSR's role in decreasing service sabotage behavior exhibited by victims of abusive supervisors in the service sector.

Another sleepless night: Does a leader's poor sleep lead to subordinate's poor sleep? A spillover/crossover perspective.

Given the importance of sleep to an individual's health and well-being, relatively little research has been conducted in the management and organizational behaviour literature on the relationship between sleep and work behaviour. Using spillover/crossover theory, we extended the current literature by investigating the possible supervisor-subordinate sleep relationship and introduced a serial mediation mechanism to answer how a supervisor's poor night's sleep translates into his/her subordinate's poor night's sleep. We conducted an experience sampling study involving 101 supervisors and subordinates over five consecutive working days (N = 505 occasions). Results verified that the spillover effect of supervisors' poor sleep on their next-day abusive supervisory behaviour has a crossover effect on their subordinates' poor sleep. Finally, results indicated that subordinate's physical exercise has the capacity to mitigate the influence of abusive supervision on subordinate' poor sleep. Future research should continue to examine the supervisor-subordinate sleep relationship and identify interventions in both the work and non-work domains of supervisor and subordinates as avenues for improving sleep health.

Relationship of forest biomass carbon with biophysical parameters in north Kashmir region of Himalayas.

Biophysical parameters affecting biomass carbon have been emphasized in the Paris Agreement for realizing climatic benefits from mitigation projects. The present study was conducted to assess the relation of biophysical parameters with forest biomass carbon in north Kashmir region of Himalayas. The relation of biomass carbon was assessed with (1) species type or strata including Cedrus deodara, mixed I (Cedrus deodara-Pinus wallichiana), mixed II (Abies pindrow-Picea smithiana) and Pinus wallichiana, (2) altitude (1292-2911 m amsl), (3) crown density, (4) aspect, (5) tree count or density and (6) location. Using a stratified sampling design, a total of 188 quadrats of 0.1 ha were laid across the entire region representing different biophysical parameters. Field observation including diameter at breast height and height were recorded and sample biomass (t ha-1) was estimated using volumetric equations. The observed relation of aboveground biomass carbon with species revealed a trend of mixed II ˃ Cedrus deodara ˃ mixed I ˃ Pinus wallichiana. A positive but weak correlation (R2 = 0.02) was found between aboveground biomass carbon and altitude. A reasonably good correlation (R2 = 0.40) was observed to exist between aboveground biomass carbon and crown density. The highest value of average biomass carbon (72.63 t ha-1) was recorded for the north-eastern aspect whereas the lowest value (44.60 t ha-1) was recorded for the eastern aspect. The aboveground biomass carbon and tree count was found positively correlated (+ 0.475, R2 = 0.48). Forest biomass carbon fluctuates within the same geographical region with a variety of biophysical factors. The growth rate of species, photosynthetic ability under different crown densities and climatic conditions could address the reasons for this variability. Biophysical relations of forest biomass carbon can be viewed as an important input for guidelines and policy matters on climate change.
