Does enterprise social media use promote employee creativity and well-being?

Despite the increased use of Enterprise Social Media (ESM) worldwide, its adverse impact on firms’ employees, such as exhaustion, has not been researched sufficiently. This is a critical gap in the literature since employees’ well-being is crucial to maintaining their productivity. The current study addresses this gap by examining whether interruption overload and psychological transition affect the relationship of employees’ socio-instrumental use of ESM with ESM-related exhaustion and employee creativity, respectively. We utilized the Conservation of Resources (COR) theory to conceptualize the mediation effect of interruption overload and psychological transition on the hypothesized associations. We also used the Regulatory Focus Theory (RFT) to propose the moderation effect of promotion and prevention-focus of employees on these associations. Cross-sectional data collected from 323 employees of firms in China were analyzed to test the proposed associations. Our findings suggest that both interruption overload and psychological transition mediate the association of ESM usage with exhaustion and creativity, respectively. Furthermore, the results revealed that promotion-focus strengthens the positive relationship between ESM usage and psychological transition, whereas prevention-focus of weakens the positive relationship between ESM usage and interruption overload. The study contributes key theoretical and practical insights to set an agenda for further research and aid managerial decisions.publishedVersio

Charting the path toward a greener world: A review of facilitating and inhibiting factors for carbon neutrality

The carbon neutrality (CN) literature has witnessed a mushrooming growth but also limited attempts to systematize the mass of evidence running in multiple directions. The consequent accumulation of fragmented insights can confuse concerned stakeholders, causing them to neglect or miss crucial discussions. Our study addresses this concern by undertaking a systematic literature review (SLR) of congruent studies to delineate the facilitating and inhibiting factors that support or impede the efficacious achievement of CN targets. Given the vastness of the extant literature, we limited our review to five sectors: manufacturing, energy, transportation, agriculture, and construction (METAC), since these are known to be among the highest contributors to emissions. Using a rigorous search and filtration protocol, we shortlisted 149 studies for inclusion in the review. Going beyond the curation of insights and identifying research gaps to suggest potential research questions for future investigations, our SLR contributes significantly by synthesizing facilitators and inhibitors from the reported evidence. At the same time, identifying stimulating forces and impeding hurdles helped us highlight areas requiring policy attention and managerial action to support the achievement of CN targets.publishedVersio

Unpacking the relationship between technological conflicts, dissatisfaction, and social media discontinuance intention: An integrated theoretical perspective

Previous research has largely overlooked the examination of the association between family, work, and personal (FWP) conflict, user dissatisfaction, and subsequent discontinuation intention in the context of social networking sites (SNS). Addressing this research gap, the present study aims to present an integrated theoretical perspective that combines Expectancy Disconfirmation Theory (EDT) and Merton's functions. By doing so, we seek to provide a comprehensive understanding of the factors influencing SNS withdrawal behavior. To achieve this objective, data were collected from 360 SNS users using a time-lag method across three waves, and Structural Equation Modeling (SEM) was employed for data analysis. The findings of our study reveal that all three disconfirmation-based factors (i.e., FWP conflicts) positively contribute to SNS user dissatisfaction, which subsequently leads to users' intention to discontinue their SNS usage. Additionally, we explored the moderating role of Merton's functions, specifically manifest and latent functions, in influencing users' decisions to discontinue SNS use. The results indicate that the manifest functions of social media weaken the relationship between dissatisfaction and discontinuation intention, whereas the latent functions do not exhibit a significant interaction effect. By proposing a dual theoretically integrated mechanism of SNS discontinuation intention, study contributes to the existing literature in the field of information systems. Furthermore, our findings provide valuable insights for managers regarding the timing and manner in which social media FWP conflicts can lead to user dissatisfaction. This knowledge can assist in the development of effective strategies aimed at retaining users in SNS and enhancing their overall user experience

Optimal Selection of Integrated Electricity Generation Systems for the Power Sector with Low Greenhouse Gas (GHG) Emissions

Cheap and clean energy demand is continuously increasing due to economic growth and industrialization. The energy sectors of several countries still employ fossil fuels for power production and there is a concern of associated emissions of greenhouse gases (GHG). On the other hand, environmental regulations are becoming more stringent, and resultant emissions need to be mitigated. Therefore, optimal energy policies considering economic resources and environmentally friendly pathways for electricity generation are essential. The objective of this paper is to develop a comprehensive model to optimize the power sector. For this purpose, a multi-period mixed integer programming (MPMIP) model was developed in a General Algebraic Modeling System (GAMS) to minimize the cost of electricity and reduce carbon dioxide (CO2) emissions. Various CO2 mitigation strategies such as fuel balancing and carbon capture and sequestration (CCS) were employed. The model was tested on a case study from Pakistan for a period of 13 years from 2018 to 2030. All types of power plants were considered that are available and to be installed from 2018 to 2030. Moreover, capacity expansion was also considered where needed. Fuel balancing was found to be the most suitable and promising option for CO2 mitigation as up to 40% CO2 mitigation can be achieved by the year 2030 starting from 4% in 2018 for all scenarios without increase in the cost of electricity (COE). CO2 mitigation higher than 40% by the year 2030 can also be realized but the number of new proposed power plants was much higher beyond this target, which resulted in increased COE. Implementation of carbon capture and sequestration (CCS) on new power plants also reduced the CO2 emissions considerably with an increase in COE of up to 15%

Sustainable infrastructure, energy projects, and economic growth: mediating role of sustainable supply chain management

Economic integration and infrastructure connectivity among countries has garnered significant interest due to its immense scale and potential political and economic impact. Special economic zones (SEZ), energy projects, and sustainable infrastructure are influential catalysts that have the potential to boost economic stability and promote growth through the execution of sustainable supply chain management (SSCM) practices and adoption of a friendly approach to glocalization. However, literature on Supply Chain Management has provided limited coverage on this phenomenon. This research investigates the potential of SEZs, energy projects, sustainable infrastructure as key drivers for building economic resilience. It also examines the mediating role of SSCM and glocalization. Data was gathered from participants who were knowledgeable about the economic landscape and engaged in activities related to SEZs, sustainable infrastructure, and energy projects through a questionnaire. The study employed structural equation modeling (SEM) technique to investigate the hypothesis and examine the mediating role. The study findings indicate that SEZ establishments foster economic resilience by attracting foreign investment, promoting industrial diversification, and facilitating technology transfer. Energy projects, including development of renewable energy sources and energy infrastructure, enhance energy security and mitigate potential risks associated with energy scarcity. Through effective supply chain management, responsible sourcing, green logistics, and waste reduction, economic resilience can be bolstered. Also, glocalization, which seeks to reconcile global and local viewpoints, plays a vital role in ensuring economic stability. The present research thus enhances academic comprehension of the intricate interactions between energy projects, sustainable infrastructure, sustainable supply chain management, and economic growth

Untangling the role of power in knowledge sharing and job performance: the mediating role of discrete emotions

Purpose The purpose of this study is to empirically examine how psychological power explains dual conflicting emotions, influences and jeopardises knowledge sharing and eventually affects job performance. Specifically, this study argues that psychological power can induce feelings of pride and anxiety, which have opposite downstream effects on employees' knowledge sharing and tasks, proactive and affiliative (TPA) performances. Design/methodology/approach This study tested the model using three waves of multi-source data from 46 teams and 357 respondents in the information technology and software industry in China. This study used multilevel structural equation modelling with Mplus 7.4 to examine the within-level team variance and thereby estimated the confidence intervals for the direct and indirect paths. Findings The results indicate that increased psychological power can cause contradictory emotions (i.e. pride and anxiety). Pride positively mediates the indirect influence of psychological power on knowledge sharing and TPA performance, while anxiety negatively mediates the above-mentioned indirect relationships. Research limitations/implications This study provides a novel perspective on how psychological forces shape people's emotional experiences and subsequently their motivation to share knowledge and job performance. By integrating the existing power literature rooted in the approach/inhibition theory of power and cognitive appraisal theory of emotion, we identify two discrete emotions as underlying mechanisms between increased psychological power and motivation to share knowledge and job performance. Practical implications This research provides insights for managers regarding the ways in which psychological power can stimulate individuals to engage in negative behaviour towards others. Managers, in turn, must consider self-regulation to control this negative impact. Originality/value This study is among the earliest to examine the role of discrete positive and negative emotions caused by increased psychological power, which subsequently affect knowledge sharing and TPA performance

Objective: To evaluate the epidemiology of clostridioides difficile infections and colonisation in a tertiary-care setting. Method: The cross-sectional study was conducted at the Combined Military Hospital, Rawalpindi, Pakistan, from June 1, 2017, to October 31, 2019, and comprised adult patients admitted in high-risk units of the hospital for any disease experiencing watery stools after 48 hours of hospital admission and passing more than 3 stools per day with no other recognised aetiology. Stool samples of the participants, diagnosed with antibiotic associated diarrhoea, were submitted forglutamate dehydrogenase antigen assay and clostridioides toxin A/B assay detected by enzyme-linked immunosorbent assay and clostridioides difficile toxin gene detection by polymerase chain reaction. Clostridium difficile-associated diarrhoea was diagnosed by a positive toxin assay or polymerase chain reaction. Data was analysed using SPSS25. Results: Of the 715 subjects, 322(45%) were males and 393(55%) were females. The overall mean age was 56.64±8.57 years, and 488(68.3%) were aged 60 years. The incidence of clostridioides difficile-associated diarrhoea was found in 10(1.4%) patients and was highest in oncology unit 3(4.3%). No positive case was detected from the high dependency unit and the surgical ward. All the10(1.4%) positive cases were on >2 antibiotics with a combination of oral vancomycin and intravenous metronidazole. Mortality rate was significantly higher in the positive cases compared to those with clostridioides difficile colonisation (p<0.05). Conclusion: The incidence of clostridioides difficile-associated diarrhoea was found to be low. Continues..

Analysis of Flow-Induced Vibrations in a Heat Exchanger Tube Bundle Subjected to Variable Tube Flow Velocity

Tube bundles of shell and tube-type heat exchangers often fail because of vibrations produced in tubes due to flow. The turbulence in the flow is the primary cause of vibrations in the tubes. In this study, a tube positioned in the third row of the tube bundle was considered to determine the vibrational response of the heat exchanger tubes. The tube bundle was parallelly arranged in a triangular (60°) configuration having a pitch to diameter (P/D) ratio of 1.44. The internal tube flow velocity ranges from 0 to 0.371 m/s and the shell side velocity ranges from 0.5 m/s to 2 m/s. The experimentation shows that the amplitude of vibration without flow inside the tube is less as compared to the amplitude with the flow. Furthermore, as the velocity of internal tube flow escalates; the amplitude of tube vibrations tends to escalate as well even when the shell side flow velocity is kept constant. The data points from experiments tend to reside in the unstable region of the stability map and particularly on the map’s left side, although the tube shows stable vibration behaviour as confirmed by the experimental results. Thus, further, development can be done by modifying the theoretical models to predict the realistic stability behaviour of tubes with internal tube flow
