Item Emerging Advancements in Sustainable Entrepreneurship: A Systematic Literature Review and Bibliometric Analysis(Springer Nature, 2023) Mishra, R.; Kiran, K.B.Entrepreneurship has been recognized as a crucial driver for a nation’s economic growth, wherein the entrepreneurs exploit social and environmental assets to generate financial gains, making them accountable to the community and the environment. The current state of the environment, the socioeconomic divide, and insufficient access to resources and opportunities are the primary concerns. Recent academic works have highlighted the concept of sustainable entrepreneurship as a solution to minimizing the negative effects of entrepreneurial industries on environmental deterioration and social inequality. Scholarly interest in this field has grown in recent years as a result of its ability to incorporate the triple bottom line of people, planet, and profit. However, there is still a lack of awareness and understanding of nature and the future of sustainable entrepreneurship in both theory and practice. Therefore, this systematic review paper along with the bibliometric analysis aims to show how sustainable entrepreneurship has changed after the introduction of Sustainable Development Goals (SDGs), focusing on recent research trends. This literature review will reveal the trend and ascertain the future directions for novel and senior researchers in the field of sustainable entrepreneurship. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd 2023.Item Exploring Hidden Behaviors in OpenMP Multi-threaded Applications for Anomaly Detection in HPC Environments(Springer Science and Business Media Deutschland GmbH, 2025) Bhowmik, B.; Girish, K.K.; Mishra, P.; Mishra, R.In high-performance computing (HPC), multi-threaded applications using OpenMP face complex challenges in identifying hidden performance issues, often due to resource conflicts, software inefficiencies, and hardware anomalies. These subtle issues can significantly degrade performance and reduce system reliability. This paper introduces an innovative approach designed to address these concealed issues in OpenMP multi-threaded applications. The proposed method integrates a Random Forest classifier with anthropomorphic diagnosis to effectively identify and diagnose performance-affecting problems. The approach has demonstrated a remarkable ability to detect 90% of performance-affecting issues that are often obscured within complex HPC environments. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.Item Discovering spammer communities in twitter(Springer New York LLC barbara.b.bertram@gsk.com, 2018) Bindu, P.V.; Mishra, R.; Santhi Thilagam, P.S.Online social networks have become immensely popular in recent years and have become the major sources for tracking the reverberation of events and news throughout the world. However, the diversity and popularity of online social networks attract malicious users to inject new forms of spam. Spamming is a malicious activity where a fake user spreads unsolicited messages in the form of bulk message, fraudulent review, malware/virus, hate speech, profanity, or advertising for marketing scam. In addition, it is found that spammers usually form a connected community of spam accounts and use them to spread spam to a large set of legitimate users. Consequently, it is highly desirable to detect such spammer communities existing in social networks. Even though a significant amount of work has been done in the field of detecting spam messages and accounts, not much research has been done in detecting spammer communities and hidden spam accounts. In this work, an unsupervised approach called SpamCom is proposed for detecting spammer communities in Twitter. We model the Twitter network as a multilayer social network and exploit the existence of overlapping community-based features of users represented in the form of Hypergraphs to identify spammers based on their structural behavior and URL characteristics. The use of community-based features, graph and URL characteristics of user accounts, and content similarity among users make our technique very robust and efficient. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.Item Particulate matter (PM10) enhances RNA virus infection through modulation of innate immune responses(Elsevier Ltd, 2020) Mishra, R.; Krishnamoorthy, P.; Gangamma, S.; Raut, A.A.; Kumar, H.Particulate matter (PM10) enhances severity of influenza virus infection through skewing innate immunity via modulation of metabolic pathways-related genes.; Sensing of pathogens by specialized receptors is the hallmark of the innate immunity. Innate immune response also mounts a defense response against various allergens and pollutants including particulate matter present in the atmosphere. Air pollution has been included as the top threat to global health declared by WHO which aims to cover more than three billion people against health emergencies from 2019 to 2023. Particulate matter (PM), one of the major components of air pollution, is a significant risk factor for many human diseases and its adverse effects include morbidity and premature deaths throughout the world. Several clinical and epidemiological studies have identified a key link between the PM existence and the prevalence of respiratory and inflammatory disorders. However, the underlying molecular mechanism is not well understood. Here, we investigated the influence of air pollutant, PM10 (particles with aerodynamic diameter less than 10 ?m) during RNA virus infections using Highly Pathogenic Avian Influenza (HPAI) – H5N1 virus. We thus characterized the transcriptomic profile of lung epithelial cell line, A549 treated with PM10 prior to H5N1infection, which is known to cause severe lung damage and respiratory disease. We found that PM10 enhances vulnerability (by cellular damage) and regulates virus infectivity to enhance overall pathogenic burden in the lung cells. Additionally, the transcriptomic profile highlights the connection of host factors related to various metabolic pathways and immune responses which were dysregulated during virus infection. Collectively, our findings suggest a strong link between the prevalence of respiratory illness and its association with the air quality. © 2020 Elsevier Ltd; © 2020 Elsevier LtdItem Is sustainable performance in MSMEs driven by entrepreneurial orientation through knowledge management and dynamic capabilities?(Emerald Publishing, 2025) Mishra, R.; K.b, K.Purpose – Despite the extensive focus on entrepreneurial orientation (EO), its full impact on environmental, social and economic performance remains ambiguous. This study aims to clarify EO’s influence on enterprise sustainability. In addition, it investigates how knowledge management (KM) and dynamic capabilities (DCs) serve as serial mediators between EO and the sustainable performance (SP) of manufacturing micro, small and medium-sized enterprises (MSMEs). Design/methodology/approach – The proposed model’s relationships were investigated using data from 238 Indian MSMEs, collected through a standardized cross-sectional survey. A disjoint two-stage structural equation modeling (SEM) path analysis was used to derive valuable insights from the data. Findings – The findings indicate that EO’s dire impact on SP is statistically insignificant. However, through the mediating roles of KM and DCs, EO exerts a significant indirect influence. EO fosters KM processes that, in turn, enhance DCs, enabling MSMEs to innovate, recognize opportunities and manage risks effectively. This highlights the essential pathways through which EO contributes to achieving SP. Research limitations/implications – These findings offer practical guidance for MSME entrepreneurs, administrators and scholars on implementing KM and DC strategies to strengthen SP and foster long-term competitive advantage. Originality/value – To the best of the authors’ knowledge, this is one of the first studies to examine the serial mediation of KM and DC in the EO–SP relationship within Indian MSMEs. By integrating the dynamic capability view (DCV), knowledge-based view (KBV) and triple bottom line (TBL) framework, this study provides novel theoretical insight and responds to recent calls for deeper exploration of how strategic enablers shape sustainability outcomes in emerging economies. © 2025 Emerald Publishing LimitedItem Unveiling the dynamic capabilities' influence on sustainable performance in MSMEs: a systematic literature review utilizing ADO-TCM analysis(Emerald Publishing, 2025) Mishra, R.; Kiran, K.B.Purpose: This research endeavors to conduct a thorough and holistic analysis of the foundational elements that empower the cultivation of dynamic capabilities in micro, small and medium-sized enterprises (MSMEs). The purpose of this study is to determine whether these capabilities have a noticeable impact on the sustainable performance of these enterprises. The study aims to support future research efforts in understanding this phenomenon by filling this knowledge gap and presenting a conceptual framework, thereby enhancing the scholarly discourse in this field. Design/methodology/approach: The study consists of a systematic review of 126 articles meticulously chosen through a series of screening stages employing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework. This examination is conducted within the organized framework of antecedents, decisions and outcomes-theory, context and methods (ADO-TCM), ensuring a structured and comprehensive analysis. Findings: The study uncovers significant insights, identifying four key antecedents: resource base, organizational learning, managerial expertise and external environment management. These factors are instrumental in fostering dynamic capabilities within the enterprise, leading to sustainable entrepreneurial success and a competitive advantage over rivals. Research limitations/implications: By comprehending the mechanisms by which dynamic capabilities are established within the enterprise, this study provides a valuable resource for entrepreneurs, professionals and managers, offering them practical insights to leverage. Originality/value: This systematic literature review is the initial attempt to explain how dynamic capabilities can be used to enhance and accomplish sustainable performance in the context of MSMEs. © 2024, Emerald Publishing Limited.Item Exploring MIL-101 (Cr) and Its Polymeric Composites as Potential Adsorbents for Volatile Iodine from Nuclear Off-gas: A Detailed Experimental and Computational Study(American Chemical Society, 2025) Kolay, S.; Kancharlapalli, S.; Samanta, S.; Muhiuddin, M.; Jha, P.; Pagare, A.; Mishra, R.Owing to the rapid growth of nuclear energy as a sustainable, affordable, and clean energy source, the entrapment of radioactive iodine released from the nuclear off-gas stream is considered a vital concern. We view MOFs as potential futuristic adsorbents for this remedy. Herein, we examined the gravimetric iodine adsorption characteristics of radiation and chemically stable MIL-101(Cr) and its polymeric composites with variation of temperatures. The saturation adsorption capacity shown by pristine MIL-101(Cr) is 4.1 g I2 g-1, and the saturation capacity of composites varies based on MIL-101(Cr)’s concentrations. MIL-101(Cr)@PES 2:1 shows an uptake capacity of 2.1 g I2 /gbead, which is ? 350% superior to the reported HKUST-1@PES and ?150% higher compared to MOF-808@PVDF0.7. Based on various spectroscopic studies and DFT calculations, probable host-guest interactions leading to enhanced I2 adsorption have been elucidated. The open Cr metal site acts as the initial adsorption site for I2 that gets converted into iodide and afterward to higher polyiodide through the transfer of charge from the host matrix. These findings suggest that MIL-101(Cr) can be considered one of the potential alternate adsorbents for radioactive iodine. © 2025 American Chemical Society.
