Career sustainability; Collaborative service robots; Humanrobot collaboration; Innovativeness; Mixed methods approach; Trust
Purpose This study aims to explore how the integration of collaborative service robots (cobots) in the workplace influences employees long-term career sustainability. Specifically, it investigates the moderating roles of perceived innovativeness, trust and employee type in this relationship. The research integrates insights from decent work theory, career sustainability theory, perceived innovativeness theory and initial trust theory to develop and validate a comprehensive conceptual framework. Design/methodology/approach A sequential mixed-method design was adopted. In Phase I, qualitative data were gathered through in-depth interviews with ten senior women managers from software development firms in India. Using grounded theory analysis via NVivo, key themes and constructs were identified. In Phase II, a structured questionnaire was developed based on these findings and distributed among employees working in manufacturing, logistics and hospitality sectors industries actively using service robots. A total of 755 usable responses were analysed using structural equation modelling with SmartPLS 4. Findings The analysis confirmed that humanrobot collaboration effectiveness, perceived working conditions and perceived autonomy significantly impact employees career sustainability, as reflected through their health, happiness and productivity. Furthermore, both trust in service robots and perceived organisational innovativeness emerged as significant mediators in these relationships. In addition, the strength of these relationships varied across managerial and non-managerial employees, highlighting the contingent role of employee type in shaping career sustainability outcomes in robot-enabled workplaces. Practical implications The findings provide actionable insights for HR professionals, technology managers and policymakers by underscoring the need for role-sensitive implementation strategies when introducing collaborative robots. Tailoring trust-building and innovation initiatives according to employee roles can help ensure that automation supports, rather than undermines, sustainable career development. Originality/value This study advances the human-centred automation literature by introducing employee type as a critical boundary condition in the relationship between collaborative robotics and career sustainability. Through a multidisciplinary and mixed-methods approach, it offers nuanced theoretical and practical contributions to understanding differential employee experiences in technologically augmented work environments. 2026 Emerald Publishing Limited

Exploring the mediating role of job and life satisfaction between workfamily conflict, familywork conflict and turnover intention
Employee retention; Family-to-work conflict; Inter-role conflict theory; Job satisfaction; Life satisfaction; Turnover intention; Women workforce; Work-to-family conflict
Purpose: This study investigates the influence of work-to-family and family-to-work conflict on turnover intention (career break), mediated through job and life satisfaction among Indian women in the service sector, using role conflict theory as the base. Design/methodology/approach: A total of 421 usable responses from women who had taken a career break were collected using a 36-item scale from six major metro cities in India through social and digital media platforms. A purposive-cum-snowballing sampling method was adopted. The hypotheses were tested using structural equation modeling (SEM) through AMOS. Findings: Findings suggest that job satisfaction (JS) is a significant predictor of turnover intention, both when work spills into the family domain, and family responsibilities spill into the work domain, thereby confirming the mediating influence of JS. Interestingly, life satisfaction (LS) only seems to mediate between inter-domain conflict and turnover intention partially. Research limitations/implications: This is a descriptive study, and is thereby limited in terms of its generalizability, specifically as it included respondents only from six major metro cities in India. Practical implications: The extended work-family conflict model could help managers structure organizational interventions that support women to deal with the challenges of managing the demands of both work and family domains, thereby reducing the negative influence on JS. Such initiatives could help reduce career breaks among women. Originality/value: We explored the cause of career breaks among Indian urban women employed in the service sector, using the extended model of inter-role conflict and their attitudes towards both life and job. 2024, Emerald Publishing Limited.

Structured text programming to visualize the distribution of packages on a conveyor
Automation is a process of increasing production and reducing the downtime of any industry. With the integration of sensor data to the cloud using an OPC-VA communication protocol, the automation becomes more prominent and interesting. However, many existing industrial controllers do not support open platform communication unified architecture (OPC-VA) and it needs an IIoT device to connect the cloud. The existing programmable logic controller in any industry have to be connected to an IIoT device through Ethernet. Sensors connected to the controller will transmit the data to the IIoT device. The transmission can also be bidirectional. In this paper, a conveyor which distributes packages is simulated in Codesys and it is visualized in a human-machine interface (HMI) screen which is in-built in the software. The hardware set-up is made with the industrial controller to execute the same. A methodology to send the data from the controller to the cloud using open platform communication unified architecture (OPC-UA) is proposed 2023 IEEE.

Meaning in life buffers mental health risks in South Indian transgender (Hijra) women
Existentialism; Meaning in life (MIL); Mediation; Mental health; Quality of life (QOL); Transgender
Purpose This study aims to investigate the mediating role of meaning in life (MIL) in the relationships among depression, anxiety, stress (DAS) and quality of life (QOL) among transgender (Hijra) women in South India. The concept of QOL extends beyond the absence of negative mental states such as DAS; it includes overall mental health, well-being and personal evaluations of life circumstances. Design/methodology/approach This study is based on a sample survey of 302 transgender women selected via convenience sampling from five states in South India. The MIL scale, Depression, Anxiety and Stress Scale (DASS-21) and QOL tools were culturally validated and tested, with reliability confirmed through a pilot study (n = 15). Correlation, regression and mediation analyses were conducted to explore the relationships. Findings A strong positive correlation between MIL and QOL was found. The DAS score has a significant negative correlation with QOL. The Presence of Meaning (PoM) subscale emerged as a crucial predictor for overall QOL, whereas the Search for Meaning (SoM) subscale showed predictive value for psychological health. MIL negatively mediates the relationship between DAS, and QOL, suggesting that it buffers mental health risks. Originality/value These findings reinforce the notion that meaning-making is an active life-affirming process, particularly for transgender women navigating adversity. The POM enriches the QOL and acts as a buffer against existential despair. This highlights the need for interventions that foster meaning-making as a pathway to resilience, emphasizing agency, authenticity and purpose pursuit in the face of existential anxiety. 2025 Emerald Publishing Limited

Catalysts of Change: The Transformative Journey from HR 1.0 to HR 5.0 Innovations, Challenges, and Strategies in Human Resource Management with Technology and Data-Driven Integration
Challenges and Strategies in HR Management; Changes of HR Management; Digitalization of HRM; HR 1.0-HR 5.0 and Beyond; Human Resources Management; Information Technology and Data-Driven Decision Making; Innovation and Application in HRM
Human Resource Management (HRM) has evolved significantly, transitioning from HR 1.0 to HR 5.0 due to technological advancements, shifting demographics, and the demands of the global business environment. This chapter highlights the evolution of HRM discussions, focusing on the key changes, concerns, and approaches that have characterized this transformation. In the HR 1.0 phase, the emphasis was on paperwork and routine clerical tasks. This laid the basis for the kind of advancement that was HR 2.0, which brought into account computerization and rudimentary data interconnection. In HR 3.0, SHRM became dominant, meaning that organizational HR practices were oriented only to achieving strategic objectives. There was a shift in the application of digital technology in performing human resource activities under the emergence of HR 4.0. The present phase is called Human Resources 5.0 (HR 5.0), which marked the strain referred to as ''People First." This approach is a mixture of Technologies Focus and Humanity Focus with an ample concern on the experience and emotional state of the employees fused with the capacity of the organizations to deal with competitive issues common to most firms. It also explores the influences that have led to these changes such as; technological developments, geographic expansion, and prospective staff demands. It also looks at possible risks linked to each shift among them, resistance to change in organization cultures, threats to data privacy amongst others plus the need to acquire higher skills. Moreover, the triple-layered paper maps actionable approaches toward the transformation of HR that are supported by cases that focus on learning culture, diversification, inclusion, and the utilization of big data. Reading through this paper to understand how HR has evolved from 1.0 to 5.0, will help HR managers, and organizations get ideas on how to meanwhile shape their human resource management strategies and advancement in the ever-growing global economy. 2025, The Research Publication.

Enhancing Disease Prediction in Healthcare: A Comparative Analysis of PSO and Extreme Learning Approach
Disease Prediction System; Extreme Learning Machine (ELM); Particle Swarm Optimization (PSO)
The healthcare business generates a tremendous quantity of data, and the goal is to collect it and use it effectively for analysis, prediction, and treatment. The best approach to disease management is disease prevention through early intervention. There are a number of methods that can advise you on how to treat a specific sickness, but much fewer that can tell you with any degree of certainty if you will actually get sick in the first place. Preprocessing, feature selection, feature extraction, and model training are all parts of the proposed method. The suggested layout includes a preprocessing stage that takes care of things like moving average, missing values, and normalization. Feature selection describes the process of selecting the most relevant features from a dataset. After gathering features, the models are trained using PSO-ELM. The proposed strategy is superior to the widely used PSO and ELM. 2023 IEEE.

The Optimization of Output of Wind Turbine with the Ongoing Grid System through BP Method Using ANN
ANN; automation; BP; design optimization; wind turbines
Wind turbines are intricate devices that need careful planning, evaluation, and installation to guarantee peak performance under a range of environmental circumstances. Comprehensive load calculations, performance evaluations, and iterative optimisation processes are all part of the design process. However, complex simulation techniques are required to adequately depict the non-linear behaviour of wind turbine systems because of their complicated structure. Automation of optimisation processes and simulation executions is crucial to optimise the design process and manage the large number of simulations that are needed. This work provides a thorough framework using back propagation (BP) and artificial neural networks (ANN) for simulation and optimization that will make it easier to manage and automate the execution of iterative simulations during the design and development of wind turbines. The framework's main goals are to make design load case simulations easier and optimise activities more automatically. The framework makes it possible to optimise wind turbine systems and explore design options more effectively by automating these procedures. Three example optimisation jobs illustrate the framework's versatility and functionality. 2024 IEEE.

Exploring the far-reaching consequences of malnutrition during pregnancy and beyond: A comprehensive review
Deficiency manifestations; Development; Fetal; Malnutrition; Microbiome; Supplementation
In India, maternal and infant malnutrition continues to be a significant contributor to health problems. Fetal malnutrition can result from an inadequate nutrient supply, necessary nutrition services, and ideal practices before, during, and following pregnancy. This comprehensive review delves into the complex relationships among hormone changes, microbial ecosystems, and nutrition, and how these relationships affect the health of mothers and their offspring. The review highlights how important it is to maintain good nutrition during pregnancy and to comprehend the dietary modifications that pregnant people make on their own to create interventions that work. Important minerals like calcium, iron, folic acid, iodine, and vitamin D are covered. Acknowledging the mutualistic association between the eating habits of mothers and the diverse microbiomes found in their gut, vagina, and oral channels, the review explores the influence on hormone levels and their consequences during gestation. Diverse fetal developmental needs are depicted by the table that outlines food requirements for each of the three trimesters. The detrimental effects of poor prenatal nutrition on a mothers health and its repercussions for neonates are examined. The effects of malnutrition after delivery, including difficulties throughout pregnancy, healing periods, and general effects on mental and physical health, are well studied. The study, which adopts a worldwide viewpoint, finds that societal norms, information gaps, and poverty are the main causes of malnutrition. Prevention techniques are discussed, emphasizing the significance of taking a comprehensive approach to addressing this vital issue in both the Indian and global contexts. 2024 Visagaa Publishing House.

Perception vs. reality: Analysing the nexus between financial literacy and fintech adoption
digital lending; financial literacy; fintech; mobile banking; mobile payments
Fintech has revolutionized the financial services sector, fundamentally transforming how individuals and businesses manage their finances. However, effective and responsible utilization of these innovative services may require a certain degree of financial competence. To explore this possibility, this study investigates the nexus between financial literacy and fintech usage in the Indian context, considering two distinct measures of financial literacy. Primary data were collected conveniently from 391 respondents through a cross-sectional survey. Probit regression was applied to analyze the relationship between the two dimensions of financial literacy and the adoption of fintech services across three segments: mobile banking, mobile payments, and digital lending. The findings reveal a positive relationship between individuals subjectively perceived financial literacy and their propensity to use all three fintech services. Conversely, objectively measured financial literacy demonstrates a positive association only with the likelihood of using mobile banking. The study also identifies demographic characteristics as contributing factors to variations in fintech adoption. The studys findings hold value for policymakers and fintech service providers, as they underscore the importance of enhancing individuals subjective perceptions of their financial abilities to promote wider adoption of fintech services.

Does Fintech Usage Alter the Relationships Between Financial Literacy, Behaviour and Well-Being? Evidence from India
financial behaviour; financial literacy; financial well-being; fintech usage
The emergence of fintech has rapidly transformed the way people manage their finances, yet its impact on personal financial outcomes remains relatively understudied. This study aims to examine how fintech usage (FTU) influences the relationship between financial literacy (FL) and financial well-being (FWB) through financial behaviour (FB) using a moderated mediation model. Using a proprietary dataset, the hypothesised relationships are analysed applying the PROCESS macro in IBM SPSS Statistics. The analysis reveals that FB is a partial mediator in the FL-FWB equation, while FTU negatively moderates the relationship between FL and FB. However, FTU does not significantly moderate the relationship between FL and FWB. The findings carry significant implications for policymakers and fintech service providers. Policymakers should strive to include a digital literacy component in financial education programs to better equip individuals to navigate todays digitalised society, while fintech companies should focus on designing products that complement users FL and facilitate the adoption of financially healthy behaviours.

Does Fintech Usage Improve or Impair Financial Behavior? Evidence from Indian millennials
financial behavior; Financial literacy; fintech usage; objective financial literacy; subjective financial literacy
The fintech revolution has transformed the landscape of personal finance, but its impact on individual financial behavior remains underexplored. Addressing this gap, the present study examines how fintech usage interacts with financial literacy to shape financial behavior among Indian millennials. Using a proprietary dataset, the study employs PLS-SEM to assess the moderating role of fintech usage in the relationship between financial literacy and financial behavior, considering both objective and subjective dimensions of financial literacy. The findings indicate that while financial literacy positively influences financial behavior, using fintech weakens this association. This negative influence is especially evident among users who overestimate their financial competence. The direct impact of fintech usage on financial behavior is also negative, showcasing the need for fintech services that complement users' financial literacy and promote financially healthy behaviors. These findings shed light on the darker side of fintech adoption and have significant implications for policymakers, fintech service providers, and consumers, emphasizing the need for tailored financial literacy programs that promote responsible fintech usage and encourage financial discipline. 2025 Academy of Taiwan Information Systems Research.

Synthesis, in vitro and theoretical studies on newly synthesized deep blue emitting 4-(p-methylphenylsulfonyl-5-aryl/alkyl)oxazole analogues for biological and optoelectronic applications
4-Ts-Oxazoles; Antimicrobial activity; Photophysical properties; Single crystal XRD
In the present study, a series of 4,5-di-substituted oxazole derivatives (compounds 2a-p) were synthesized, using a novel methodology for the simultaneous determination of their biological and optoelectronic applications. Among the screened molecules, compounds 2j, 2 l and 2o showed very good antimicrobial potencies with MICs up to 1 g/mL. Furthermore, the photophysical parameters were estimated using theoretical and experimental techniques for optoelectronic applications. The excited-state dipole moment being higher than that of the ground state, investigated using solvato-chromatic method showed a redistribution of the electron densities in the excited state for the fluorophores. The HOMO-LUMO energies of the fluorophores estimated by using density functional theory (DFT) are found to be in good agreement with the experimental values. The electrophilic and nucleophilic sites were also recognized with the help of molecular electrostatic potential 3D plots using time-dependent-DFT computational analysis. The specific and non-specific interactions between the solutesolvent were analyzed by multiple linear regression analysis using Kamlet-Abound-Taft and Catalan parameters. Further, the global chemical reactivity descriptor parameter was also calculated. The photophysical properties of the fluorophores suggest that these may be considered as potential probes for OLED, solar cell, and chemosensor applications. 2022 Elsevier B.V.

Build-up factor; Inorganic metal perovskites; Mass attenuation coefficients; Neutron removal cross-section; PAGEX; SRIM
Over the last few years, lead-free inorganic metal perovskites have gained impressive ground in empowering satellites in space exploration owing to their material stability and performance evolution under extreme space environments. The present work has examined the versatility of eight such perovskites as space radiation shielding materials by computing their photon, charged particles and neutron interaction parameters. Photon interaction parameters were calculated for a wide energy range using PAGEX software. The ranges of heavy charged particles (H, He, C, N, O, Ne, Mg, Si and Fe ions) in these perovskites were estimated using SRIM software in the energy range 1 keV10 GeV, and that of electrons was computed using ESTAR NIST software in the energy range 0.01 MeV1 GeV. Further, the macroscopic fast neutron removal cross-sections were also calculated to estimate the neutron shielding efficiencies. The examined shielding parameters of the perovskites varied depending on the radiation type and energy. Among the selected perovskites, Cs2TiI6 and Ba2AgIO6 displayed superior photon attenuation properties. A 3.5 cm thick Ba2AgIO6-based shield could reduce the incident radiation intensity to half its initial value, a thickness even lesser than that of Pb-glass. Besides, CsSnBr3 and La0.8Ca0.2Ni0.5Ti0.5O3 displayed the highest and lowest range values, respectively, for all heavy charged particles. Ba2AgIO6 showed electron stopping power (on par with Kovar) better than that of other examined materials. Interestingly, La0.8Ca0.2Ni0.5Ti0.5O3 demonstrated neutron removal cross-section values greater than that of standard neutron shielding materials - aluminium and polyethylene. On the whole, the present study not only demonstrates the employment prospects of eco-friendly perovskites for shielding space radiations but also suggests future prospects for research in this direction. 2022 Korean Nuclear Society

Charged particle interactions; Natural polymer hydrogels; Photon interactions; Radiation therapy; Tissue equivalence
Natural polymer-based hydrogels have been extensively employed in tissue engineering and biomedical applications, owing to their biodegradability and biocompatibility. In the present work, we have investigated the efficacy of hydrogels such as agarose, hyaluronan, gelatin, carrageenan, chitosan, sodium alginate and collagen as tissue equivalent materials with respect to photon and charged particle (electron, proton and alpha particle) interactions, for use in radiation therapy and dosimetry. Tissue equivalence has been investigated by computing photon mass energy absorption coefficient (?en/?), kinetic energy released per unit mass (KERMA), equivalent atomic number (Zeq) and energy absorption build-up factors (EABF) relative to human tissues (soft tissue, cortical bone, skeletal muscle, breast tissue, lung tissue, adipose tissue, skin tissue, brain) in the energy range of 0.01515MeV. Ratio of effective atomic numbers (Zeff) have been examined for tissue-equivalence in the energy range of 10keV1GeV for charged particle interactions. Analysis using standard theoretical formulations revealed that all the selected natural polymers can serve as good tissue equivalent materials with respect to all human tissues except cortical bone. Notably, sodium alginate, collagen and hyaluronan are found to have radiation interaction characteristics close to that of human tissues. These results would be useful in deciding on the suitability of a natural polymer hydrogel as tissue substitute in the desired energy range. 2021, Australasian College of Physical Scientists and Engineers in Medicine.

Dy3+doping; fast neutron removal cross section; lithium calcium borate; PAGEX; rare-earth ion-doped glasses; shielding
The exploration of trivalent rare-earth ion-doped lithium calcium borate glasses has surged recently due to their potential applications in solid-state lasers, medical imaging, and radiation shielding. This study focuses on transparent and lead-free Dy3+ doped lithium borate glasses for their efficacy as versatile radiation shields. Glasses with the chemical composition 50(Li2O): 20(CaO): 30?x(B2O3): x(Dy2O3) (x = 0.0, 0.1, 0.3, 0.5 and 1.0 mol% Dy2O3) were investigated. The structural changes in the lithium calcium borate glasses with Dy2O3 were investigated using Fourier transform infrared spectra of the synthesized glass samples. Experimental mass attenuation coefficients (?/?) of the glasses have been determined using NaI(Tl) detector spectrometer in the energy range of 0.356-1.332 MeV. Photon interaction parameters were computed using PAGEX software in the energy range of 0.015-15 MeV. Relative dose distribution (RDD) and specific absorbed fraction of energy (SAFE) were also investigated. Additionally, macroscopic fast neutron removal cross-sections ( ? R ) were computed to estimate neutron shielding efficiencies. The sample with 1 mol% Dy2O3(LBD1), displayed superior photon and neutron attenuation properties. Glasses with lower Dy2O3 doping concentrations (?1 mol%) showed comparable half-value layer and effective atomic number to reference materials with higher doping concentrations. Increasing Dy2O3 doping concentration improved photon shielding parameters, with ? R values ranging from 0.1460 to 0.1475 cm?1, higher than those of ordinary concrete, RS-360, and other reference materials. The results highlight the potential of Dy3+ doped lithium borate glasses as effective radiation shields. Further investigations on chemical combinations and Dy2O3 doping concentrations are warranted to fabricate glasses with enhanced properties. 2024 IOP Publishing Ltd.

Bismuth (III) oxide decorated graphene oxide filled epoxy nanocomposites: thermo-mechanical and photon attenuation properties
bismuth oxide; Epoxy; graphene oxide; surface decoration; X-/?-ray shielding
In this study, bismuth (III) oxide (Bi2O3) decorated graphene oxide (GO) nanocomposites were employed as novel radioprotective fillers in the epoxy matrix. Decoration of GO with Bi2O3 would transform it as carrier for Bi2O3 particles, thereby enhancing the thermo-mechanical and radiation shielding properties of the epoxy composites through effective filler distribution. Structural and compositional studies confirmed the successful decoration of Bi2O3 on the surface of GO. Thereupon, epoxy composites containing decorated fillers at different loadings (5, 10 and 15 wt%) were synthesized using solution casting technique. The correlation between surface decoration and filler loading was systematically examined as function of thermo-mechanical, viscoelastic and radiation shielding properties of the composites. These nanocomposites displayed good thermal resistance (~ 450 C), high glass transition temperature (~ 136 C), elastic modulus (~ 4.36 GPa) and storage modulus, thereby confirming the improved dispersion and better interfacial adhesion in the composites. The formation of continuous filler network across epoxy matrix formed by decorated fillers significantly improved X-ray and ?-ray shielding properties of epoxy composites in the wide energy range of medical interest (301332 keV). Shielding efficiency of these lowly loaded BGO/epoxy composites were comparable with the composites containing Bi2O3 nanoparticles alone and highly loaded microcomposites. 2022 Japan Society for Composite Materials, Korean Society for Composite Materials and Informa UK Limited, trading as Taylor & Francis Group.
