Investigating structure and spectral energy distribution of galaxies using UVIT and multi-wavelength archival data
Observational astronomy and studies of galaxy formation and evolution made dramatic advances in the past few years. This thesis deals with the multi-wavelength investigation of the different aspects of galaxy formation and evolution. The work focuses on the star formation properties of late-type spiral galaxy NGC 2336, and the properties of unresolved galaxies and of resolved early-type galaxies using spectral energy distribution (SED) fitting method. The first part of this thesis deals with the studies on the characteristics of in orbit performance of the Ultraviolet Imaging Telescope (UVIT) on-board AstroSat . AstroSat is the first Indian multi-wavelength mission and was launched on 28 September 2015 into a low Earth orbit. The UVIT instrument on AstroSat provides a unique opportunity to study the ultraviolet (UV) sky simultaneously in three channels, covering the wavelength range 1300–1800 Å (FUV), 1800–3000 Å (NUV) and 3200–5300 Å (VIS). Characterizing the in-flight properties of the instrument is a prerequisite to obtain scientifically accurate and self consistent results from the scientific programs running on it. -
Investigating structure and spectral energy distribution of galaxies using uvit and multi-wavelength archival data
This thesis deals with the multi-wavelength investigation of the different aspects of galaxy formation and evolution. The first part of this thesis deals with the studies on the characteristics of the in-orbit performance of the Ultraviolet Imaging Telescope (UVIT) on-board AstroSat. We have written a UVIT pipeline (JUDE ) to convert the Level 1 data from the Indian Space Science Data Centre (ISSDC) into scientifically useful photon lists and images. We have also performed an independent calibration of the FUV and NUV channels of the UVIT using JUDE. We found that the photometric sensitivity is about 35% that of the Galaxy Evolution Explorer (GALEX ) in the FUV broadband filter, and about the same as GALEX in the NUV broadband filter. The point spread function (PSF) of the instrument is of the order of 1.2 1.6and#8242;and#8242;. We found that the performance is close to that expected from the ground-based calibrations. We studied the recent star formation in the nearby face-on spiral galaxy NGC 2336 using the UVIT imaging. We have identified 78 bright star-forming complexes in the disk and derived their positions and estimated their properties such as luminosities, sizes, star formation rates (SFRs), colors, and ages. The FUV-NUV colors of the complexes are found to be redder in the inner region of the galaxy and become progressively bluer as the radius increases. The last part of this thesis is devoted to a model-based study of galaxies using physically motivated Code Investigating Galaxy Emission (CIGALE) package. We have studied 10,000 galaxies from GALEX SDSS merged catalog using CIGALE and estimated their properties such as stellar masses, SFRs, stellar populations, dust luminosities etc. We have classified this set of galaxies into the star-forming, intermediate and quiescent type of galaxies based on their specific SFR. We also studied the properties of dust-lane spheroidal galaxies (DLSGs) drawn from the multi-wavelength archival data in 18 bands from FUV to FIR using GALEX, SDSS, 2MASS, WISE, and AKARI surveys. -

Investigating the contrast diurnal relationship of land surface temperatures with various surface parameters represent vegetation, soil, water, and urbanization over Ahmedabad city in India
Many climatic problems have arisen due to congested and inefficient planning, reduced vegetation cover, and increased pollution from factories and vehicles. One such primary concern is increased land surface temperature (LST) contributes to the urban heat island (UHI) occurrence. This research aims to understand better the UHI effect in the region neighbouring the Indian city of Ahmedabad. MODIS sensor data (onboard Aqua and Terra platforms) and Landsat data were used for the study. The research was done for the summer, monsoon, and winter seasons in the research region, using data from thirteen years between 2003 and 2015. The current study looked at LSTs' spatial and temporal differences to assess the SUHI effect over Ahmedabad city. The association between diurnal LST and various surface variables such as vegetation, built-up, soil, water, and so on has also been examined. A variety of land surfaces influences the diurnal variations of LSTs. The diurnal associations of LST with vegetation, urbanization, soil, and water factors have been studied. The overall study of LST' relationship with all of the various parameters reveals a very significant dynamic relationship. 2022 The Author(s) -
Investigating the Determinants of Financial Well-Being: A SEM Approach
Studies reveal that the financial well-being of employees has a direct bearing on their productivity and overall well-being. The wellness initiatives organized by the information technology (IT) companies operating in India have also started focusing on the contributing aspects of financial well-being. In this context, the article explores the determinants of financial well-being of IT professionals in India. The article utilizes confirmatory factor analysis (CFA) for the analysis. The study employs a survey questionnaire covering financial literacy, financial behavior, and financial fragility. It also attempts to recognize the influence of gender and job roles (technical or managerial) in ascertaining financial well-being. The sample data used in the study include 237 professionals employed in the IT sector. The study uses partial least squared structured equation modelling (PLS-SEM) to understand the connection between the determining factors. The results indicate that financial well-being is positively influenced by financial literacy and financial behavior while financial fragility has a substantial negative impact. The financial literacy and financial fragility are significantly different between technical and managerial roles. Gender appears to have a sizeable impact on the financial behavior and financial fragility levelswomen employees performed better in both the factors. Interestingly, financial literacy levels of the two genders are not significantly different. The results show that there is a need to focus on literacy, behavior, and fragility in financial wellness programs organized by the IT industry. Further, the study recommends offering tailored financial wellness training modules created based on the job levels and gender instead of following one program, fits all standardized approach. 2023 KJ Somaiya Institute of Management. -
Investigating the Dynamic Interlinkages between Exchange Rates and the NSE NIFTY Index
This study aims at examining the short-run and long-run dynamic linkages among exchange rates and stock market index in India through a structured cointegration and Granger causality tests. Daily exchange rates of USD, EUR, CNY, JPY, and GBP to INR along with the daily movement of NSE NIFTY for a period spanning 13 years from 6 September 2005 to 31 December 2018 were used for the analysis. The results reveal that there is no evidence for a stable long-run relationship between NSE NIFTY and the exchange rates under study. However, the VAR-based Granger causality test shows that USD, JPY, and CNY have short-run causal relationship with NSE NIFTY. The NSE NIFTY also seemed to have an influence on USD expressed in terms of Indian rupee. The impulse response analysis further supports the results of the Granger causality test and provides information on the time required for the NSE NIFTY index to recover from a shock caused by the fluctuation in exchange rates. 2021 by the authors. -
Investigating the dynamics, synchronization and control of chaos within a transformed fractional SamardzijaGreller framework
In this article, in response to the limitations of existing ecological models, we address the critical need for a more comprehensive understanding of predatorprey dynamics by presenting a modified fractional SamardzijaGreller model that incorporates intra- and inter-species competitions within two predator populations. Our model stands out for being more realistic because it considers the natural competition that occurs among and between two predator species when they share a common prey We derived the local stability conditions at equilibrium points using RouthHurwitz conditions for the modified model. With the help of a suitably chosen Lyapunov function, we also obtained the global stability condition for our fractional model. The existence of chaos has been confirmed through Lyapunov exponents and bifurcation in the new system for two distinct sets of initial conditions for different fractional orders. Employing the active control method, we establish conditions for synchronization between these two fractional systems and introduce control functions for chaos management in the modified model. Numerical simulations, utilizing the generalized AdamsBashforthMoulton method, support the theoretical findings across a spectrum of fractional orders ranging from 0 to 1. We demonstrated the adaptability of the active control method for different fractional orders. A fractional order of ? equal to 1 for synchronization shows rapid convergence, but a drop to ? equal to 0.80 causes a substantial slowdown that takes almost six times more number of iterations to complete. Thus, we shed light on how the fractional order of the system plays a pivotal role in determining the speed of synchronization, with lower orders leading to a noticeable delay and higher fractional orders favoring faster synchronization. Our thorough investigation contributes to the understanding of complex ecological systems and offers practical insights into fractional chaos control mechanisms within the context of predatorprey models. 2024 Elsevier Ltd -
Investigating the Electrochemical Behavior of Flowerlike-Co-Pi-Decorated Ti3C2TxMXene for Cathodic CO2Utilization: A Sustainable Approach
The rising CO2 concentration in the atmosphere has sparked the need for research communities and industries to shift toward embracing technologies prioritizing CO2 conversion and utilization. This research presents the fabrication of flowerlike cobalt-inorganic phosphate-decorated Ti3C2Tx MXene-modified carbon fiber paper (Co-Pi/Ti3C2Tx/CFP) electrode for electrochemical CO2 fixation via benzyl chloride transformation to produce industrially and pharmaceutically important phenylacetic acid (PAA). The multilayered Ti3C2Tx, having a large specific surface area, functions as the nucleation centers for the deposition of Co-Pi and enhances its physical, chemical, and electron transmission attributes. The Co-Pi anchored to Ti3C2Tx in turn modifies the interlayer properties of MXene, prevents restacking of the layered MXene structure, provides additional electrocatalytic sites, and escalates the electrocatalytic efficiency. Cyclic voltammetry and potentiostatic electrolysis studies revealed a higher current response, lower reduction potential, and increased productivity at the Co-Pi/Ti3C2Tx/CFP electrode for benzyl chloride transformation with CO2 coupling, yielding the desired carboxylic acid. Under optimal conditions, potentiostatic electrolysis at ?1.6 V for 8 h yielded up to 62% PAA, following a diffusion-controlled two-electron reduction mechanism. Furthermore, the electrodes showed good repeatability, reproducibility of electrochemical responses, and excellent stability over 60 days. 2025 American Chemical Society -

Investigating the heterogeneity of ESG investors: evidence from emerging economies
Purpose This study aims to examine the heterogeneity in behavioural characteristics of retail investors regarding sustainable investments, identifying patterns of convergence and divergence in sustainability-oriented market behaviours. By developing and validating specialized indices for environmental, social and governance (ESG) preferences, investor sentiments, performance perceptions, investment intentions, subjective norms, cognitive biases and greenwashing concerns, this research investigates how socio-demographic factors influence these indices through assessing heterogeneity across investor segments. Design/methodology/approach The authors develop and validate five ESG behavioural indices capturing multiple dimensions of sustainable investment behaviour. Data were collected through a comprehensive survey of 511 active retail investors in the Indian stock market. Heterogeneity analysis was conducted to identify variations in behavioural characteristics across the sample. The authors use quantile regression analysis to assess heterogeneity across demographic segments (age, income, gender, employment, education and investment experience), examining how relationships vary across the conditional distribution of ESG behavioural dimensions. Findings The analysis reveals heterogeneity in ESG investment behaviour across demographic segments. Age consistently reduces ESG engagement across all dimensions, while higher income enables selective sustainability preferences but increases investment irrationality. Gender creates divergent ESG orientations, with distinct patterns in environmental versus social priorities. Employment status and education facilitate ESG adoption through stability and social learning mechanisms, whereas investment experience paradoxically generates both sophisticated awareness and fundamental skepticism. Critically, performance perceptions emerge as the primary determinant mediating demographic influences on ESG preferences, establishing that sustainability investment behaviour is instrumentally rational rather than value-expressive in emerging markets. Practical implications The findings provide insights for enhancing sustainable investment participation. Financial institutions should develop targeted educational programmes to address knowledge gaps, as awareness significantly influences ESG preferences. Recognizing investor heterogeneity is essential younger, high-income investors respond to performance narratives, while older investors seek transparency. Addressing greenwashing concerns through standardized reporting and third-party certifications builds trust. Leveraging social influence through choice architecture and behavioural nudges can overcome decision-making barriers. Income-based strategies should include structured ESG portfolios for high-income investors prone to impulsivity, while providing educational support on stable returns for price-sensitive retail investors in emerging markets. Social implications The identified behavioural market failure in sustainable investing has important implications for the development of sustainable finance policies in emerging markets. Addressing the divergence in sustainability views could accelerate the transition towards more sustainable capital markets and contribute to broader sustainability goals. The findings highlight the need for targeted initiatives and policy interventions to bridge the gap between ESG preferences and actual investment behaviour. Originality/value This study advances sustainable finance through three contributions. First, the authors develop and validate multidimensional ESG behavioural indices capturing preferences, sentiments, perceptions, intentions and irrationality among retail investors. Second, the authors establish demographic heterogeneity as a structural market characteristic challenging the homogeneous investor assumption. Third, the authors theorize performance primacy as the fundamental mechanism driving ESG preference formation, demonstrating instrumental rationality rather than value-expression. These frameworks, validated through quantile regression analysis, provide actionable insights for policymakers and practitioners designing targeted interventions across demographically diverse investor segments in emerging markets. 2026 Emerald Publishing Limited -
Investigating the Impact of Emotional Contagion on Customer Attitude, Trust and Brand Engagement: A Social Commerce Perspective
Social Commerce networks are a powerful platform for spreading positive and negative emotional contagion, which is affecting users from different perspectives, i.e., psychology, attitude, buying decision. Emotional contagion is the phenomenon of having a person's emotions and behaviours directly trigger similar emotions or behaviour in other people. This research proposes a model to analyze the factors influencing emotional contagion that, in turn, impact consumer's attitudes, trust, and brand engagement. This study used a survey approach using a structured questionnaire. Primary data was collected from 174 social media users who shop online. The proposed model was tested using multiple regression analysis. The results demonstrated that effective content, visual or text, triggers customers' emotional contagion, influencing customer attitude and trust leading to brand engagement. The research study's findings can be used for deciding on content strategies of advertisements pertaining to social commerce. 2022 Academy of Taiwan Information Systems Research.

Investigating the in-flight performance of the UVIT payload on AstroSat
We have studied the performance of the Ultraviolet Imaging Telescope payload on AstroSat and derived a calibration of the far-ultraviolet (FUV) and near-ultraviolet (NUV) instruments on board. We find that the sensitivity of both the FUV and NUV channels is as expected from ground calibrations, with the FUV effective area about 35 per cent and the NUV effective area about the same as that of GALEX. The point spread function of the instrument is on the order of 1.2-1.6". We have found that pixel-to-pixel variations in the sensitivity are less than 10 per cent with spacecraft motion compensating for most of the flat-field variations. We derived a distortion correction but recommend that it be applied post-processing as part of an astrometric solution. 2018 The Author(s). -

To ensure efficient delivery of perishable food products, food supply chains (FSCs) have advanced the usage of recent technologies and started integrating them into logistical systems. This study examines the interplay between digital capabilities, sustainable practices, logistical networks, and customer satisfaction in perishable FSCs through a cross-sectional survey of 416 Indian consumers. It draws on a comprehensive literature review that highlights the potential variables and their impacts on the perishable FSCs. The data was collected using a five-point Likert-scale questionnaire, analyzed using partial least squares-structural equation modeling (PLS-SEM), and robustness was ensured by Harman's test. The study integrates value percept theory (VPT) to develop a comprehensive conceptual framework that explains how digital capabilities and sustainable practices enhance product quality and customer satisfaction in perishable FSCs. The findings from the study explicitly support the positive moderating role of logistical networks in the relationship between digital capabilities and product quality. The findings can assist management professionals operating in the perishable food sector in enhancing their theoretical and practical comprehension of the profound influence exerted by digital capabilities, sustainable practices, and logistical networks on the crucial nexus between product quality and customer satisfaction. 2026 ERP Environment and John Wiley & Sons Ltd. -

Recently, the world is moving towards a new future where most of the communications is happening through the Internet. The use of smartphones has rapidly increased for the past two decades. People show high interest in adopting new technologies in their day to day lives. In order to connect very closely with the customers, many retailers started to expand their businesses with the help of mobile e-commerce applications. The extensive use of mobile phones and the favorable independence of time and location promised the future of mobile e-commerce applications. This created a necessity for the online businesses to understand the factors that influence customer engagement in mobile e-commerce applications. This research was aimed to provide a clear understanding on the factors that affect customer engagement in mobile e-commerce applications with respect to the age, frequency and experience of consumers. The factors like customer satisfaction, utilitarian value, ease of use, hedonic value, trust and personalized recommendations were taken into account to understand their influence on the customer engagement in mobile e-commerce applications. These factors were studied with respect to the age group of consumers and they were classified into four groups as follows: below 20years, 21 to 35years, 36 to 50years, 51years and above. Also, the effect of frequency and experience in using mobile applications towards customer engagement in mobile e-commerce applications were studied in this research. The questionnaire with 29 items were sent to 250 respondents through e-mail and other social media platforms and out of which 151 responses were taken into account for the analysis part. ANOVA tests were performed to analyze the influence of age, frequency and experience in using mobile e-commerce applications on the factors like customer satisfaction, utilitarian value, ease of use, hedonic value, trust and personalised recommendations that affect customer engagement in mobile e-commerce applications. To further analyze and group the respondents engagement in mobile e-commerce applications, k-means cluster analysis was performed. Later, ANOVA tests were performed to understand the differences among demographic profiles and cluster groups in customer engagement. From these tests, the moderating effect of age, frequency and experience factors on customer engagement were analyzed. The Author(s), under exclusive license to Springer Nature Switzerland AG 2025. -
Investigating the Role of Intelligent HR Systems in Enhancing the Relationship Between Employee Engagement and Performance: A Computational Perspective for Economic Development
This study examines the impact of Human Capital Management Practices (HCMPs), specifically employment opportunities, training, and rewards, on employee performance. Work engagement is a mediating component in this analysis. The results indicate that HCMPs enhance employee performance by increasing work engagement. This demonstrates the strategic role that HR plays in developing a motivated workforce that propels business success. Engaging employees is essential for every business to succeed in providing its clients with high-quality services; engaged employees treat customers royally and talk about the success of their organization. According to research, engaged workers are 87% less likely to quit than disengaged ones. They tend to maintain regular attendance without absenteeism, treat their work with care, and contribute to the business's growth. As a result, they are often rewarded for their dedication and commitment. The manager must communicate with employees, listen to their concerns, and reward them for improved work. Employee engagement, on the other hand, improves performance and helps the company expand. It is bothering because employees who are less engaged are more likely to leave than those who are more engaged. When workers are engaged, they work hard, do better at their jobs, and stick with the company for years. To measure the level of engagement, research indicates that companies with poor employee engagement experienced an average operational income decrease of almost 32%, created a foundation for engagement to occur easily, set goals and tracked employee engagement, and encouraged continued high engagement levels with routine public recognition for employees who are engaged. The primary task is to break the culture of dependency on leaders and develop teamwork with visibility to accountability and engagement. This empowers employees to solve their issues and provides opportunities for coaching and mentoring. High employee engagement results in high organizational performance. The Research Publication. -

Investigating the transport flexibility measures for freight transportation: a fuzzy best-worst method approach
Unpredicted disruptions force organisations to ensure flexibility for fulfilling customer demand. Enabling flexibility along the transportation system is the most suitable solution for unpredictable disruptions. Flexibility, being a potential element, requires more attention to gain competitive advantages. In this study, an effort has been made to investigate different transport flexibility measures (TFMs) related to freight transportation. Initially, an extensive literature survey is performed to identify different TFMs linked with the supply chain and logistics domain. Further, an integrated fuzzy best-worst method (FBWM) has been adopted to prioritise the identified TFMs and sensitivity analysis is performed to ensure robustness of the model. The findings of the study reflect mode, fleet, vehicle and speed flexibility as the significant flexibility measures for freight transportation. This study will help practitioners, managers and decision-makers associated with freight transportation to make better decisions to ensure flexibility in the freight transportation system.
