Spectroscopic, crystal structure and DFT-assisted studies of some nickel(II) chelates of a heterocyclic-based NNO donor aroylhydrazone: in vitro DNA binding and docking studies
Five new nickel(II) complexes have been synthesised with an NNO donor tridentate aroylhydrazone (HFPB) employing the chloride, nitrate, acetate and perchlorate salts, and all the complexes are physiochemically characterized. Elemental analyses suggested stoichiometries as Ni(FPB)(NO3)]2H2O (1), [Ni(HFPB)(FPB)]Cl (2), [Ni(FPB)(OAc)(DMF)] (3), [Ni(FPB)(ClO4)]DMF (4), [Ni(FPB)2] (5). Aroylhydrazone is found coordinating in deprotonated iminolate form in four of the complexes (1, 3, 4, 5) however in one case (complex 2), two aroylhydrazone moieties are binding to the metal centre in the neutral and anionic forms. The structure of the bisligated complex 5, found using single crystal X ray diffraction studies confirmed that the metal has a distorted octahedral N4O2 coordination environment, with each of the two deprotonated ligands coordinating through the pyridine nitrogen, imino-hydrazone nitrogen and the enolate oxygen of the hydrazone moiety. To compare and study, the electronic interactions and stabilities of the metal complexes, various quantum chemical parameters were calculated. Moreover, Hirshfeld surface analysis was carried out for complex 5 to determine the intermolecular interactions. The biophysical attributes of the ligand and complex5 have been investigated with CT-DNA and experimental outcomes show that the Ni(II) complex exhibited higher binding propensity towards DNA as compared to ligand. Furthermore, to specifically understand the type of interactions of the metal complexes with DNA, molecular docking studies were effectuated. In addition, the electronic and related reactivity behaviors of the ligand and five Ni(II) complexes were studied using B3LYP/631 + + G**/LANL2DZ level. As expected, the obtained results from Natural Bond Orbital (NBO) computations displayed that the resonance interactions (n ? ?* and ? ? ?*) play a determinant role in evaluating the chemical attributes of the reported compounds.

Oxidation reactions of carbaryl in aqueous solutions
Hydroxyl radical induced oxidation of carbaryl has been studied using steady state photolysis followed by high-resolution mass spectrometry (LC-Q-TOF-MS), pulse radiolysis, and theoretical (DFT) calculations. The reaction of ?OH with carbaryl resulted in a number of hydroxylated adduct radicals (?max - 330 nm and 390 nm; k2 - 1.2 1010 dm3 mol-1 s-1). The DFT calculations and results obtained from LC-Q-TOF-MS analysis shows the possible addition of ?OH at C1 (energetically most stable) and C7 positions of carbaryl leading to the generation of resonance stabilized hydroxycyclohexadienyl-type radicals as the immediate intermediates, which eventually converted into naphthol and a hydroxylated naphthols. LC-Q-TOF-MS results also revealed the formation of other hydroxylated derivatives and naphthoquinones that are most likely originated from the consecutive ?OH attack on the initially formed products. Naphthoquinones are found to undergo ring opening and the corresponding products are identified. The reaction of SO4?- with carbaryl, on the other hand, results the radical cation of parent molecule (?max - 320 nm and 390 nm) which exhibits reasonable stability in the pulse radiolysis timescale. Total organic carbon (TOC) analysis after H2O2/UV photolysis revealed that nearly 70% of the organic content is mineralized after 35 min of irradiation, which demonstrates the potential application of oxidative methods towards the degradation of carbaryl. 2021 Elsevier B.V. -
Enhancing instructional effectiveness using the metaverse: An empirical analysis of the role of attitude and experience of participants
The Metaverse has been gaining importance, with businesses looking to adopt the same for processes rangingfrom onboarding to customer experience. The current study has been conducted to evaluate the impact of learner characteristics on motivation to participate in metaverse-based training programs across various organizations. Based on literature and theory, two main characteristics were identified: attitude towards the metaverse and experience with the technology. Data for the study was collected using a structured questionnaire and 103 responses were collected from employees belonging to various organizations in India. The analysis and interpretation of the data was done using statistical techniques through the tool of SPSS. The study found out that both the learner characteristics have a strong positive relationship with each other, and attitude towards metaverse has a stronger relationship with learner motivation than the experience of use. The findings suggest organizations focus more on the manner in which they should introduce metaverse at the workplaces and need to keep the employee attitude towards any kind of change; more of a technological change in mind when they are strategizing to implement metaverse-based training programs. 2024, IGI Global.

Stereotype threat and psychological wellbeing in children of prisoners
Stereotypes are ideas that one holds regarding individuals because of their membership to a specific group. The current research was undertaken to study stereotype perception and stereotype threat on the psychological wellbeing of children of prisoners. Eight children of prisoners in the age range of 17 to 25 (females = 4), whose fathers were in prison for more than a year, participated in the study. Semi-structured interview method was used to collect data from the participants and data were analyzed using thematic network analysis method. Results revealed that children of prisoners strongly perceive stereotypes against them and they conform to stereotypes. Further to this, it was found that stereotype threat had positive effects in terms of increased goal-directed behavior and negative effects in terms of reduced happiness and increased feelings of anger and sadness. These Undings are discussed in light of previous literature on the effects of stereotypes on behavior. 2019 International Journal of Criminal Justice Sciences (IJCJS). -
Levelling Up Organisational Learning Through Gamification: Based on Evidence from Public Sector Organisations in India
The concept of sustainability brought into focus the need for research into how to measure and achieve sustainable growth. The triple bottom line framework and the resource-based view of the firm suggest the need for organisations to look beyond profits and take into consideration the needs and effectiveness of its workforce. Research suggests that an effective workforce can be achieved through constant learning and development. Organisations have also expressed the need for training techniques that are more effective than the traditional methods. Gamification has been proposed as one such technique, and in the current study, the researchers evaluate the effectiveness of gamification in organisational training. For the purpose of the current study, 120 participants were chosen from public sector organisations in India. This is primarily because the technology-enhanced training effectiveness model (TETEM) suggests that the effectiveness of gamification would depend on the culture of the organisation, and prior research has been based in privately owned firms. The findings are in line with the theory of gamified learning and suggest that participants of the gamified module reported higher levels of learning, reaction and learner motivation. Additionally, learner motivation was found to strengthen the impact of gamification on the learning and reaction. The Author(s) 2022. -
Evaluation of a gamified learning experience: Analysis of factors that impact the effectiveness of a gamified experience; [Avaliao de uma expericia de aprendizagem gamificada: Anise dos fatores que afetam a eficia de uma expericia gamificada]
Gamification has gone through a faddish cycle. It first gained prominence around 2012 and was quickly abandoned, as practitioners did not achieve the outcomes they expected. According to Gartner's Hype Cycle, Gamification is at a point at which one might expect wide scale adoption. However, if history is not to repeat itself and results are to be achieved as theoretically predicted, a deeper understanding of the concept is essential. In the current study, the researchers attempt to evaluate a gamified learning experience. The participants were students of a Master in Business Administration course. The students were asked to participate in a gamified module and relevant data was collected, before and after the intervention. Based on a review of literature, the researchers identified the exogenous variables of Valence, Attitude towards use of Technology and Experience with Technology. The endogenous variables identified included Reaction and Learning. The findings of the study suggest that the gamified module resulted in increase in knowledge and that Attitude, Experience and Valence significantly predicted the Learner's reaction to the experience. The findings of the study provide support to key theories in the area of gamification and insights for practitioners, on the factors to be considered before using a gamifiedlearning intervention. 2021 UNIVERSIDADE FEEVALE All rights reserved. -

A theoretical framework for gamified learning
The term gamified has been applied to a large number of processes in the organization. Marketing professionals have attempted to gamify customer experiences, while human resource managers have attempted to gamify employee processes like recruitment and onboarding. Being a powerful driver for goal-oriented behavioural change, gamification has the potential to revolutionise the way people work, collaborate, and develop. However, the application of gamification has met with limited success in the organization. Researchers have attributed this lack of success to incomplete understanding of the concept. The current study reviews literature in the area of Gamification in an attempt to arrive at a conceptual model explaining how gamification drives learning. The model proposed in this study is simple and draws from key theories related to Learning and use of technology. The purpose of the review is to provide a base for future researchers and a basic understanding for practitioners attempting to introduce gamified learning. BEIESP. -
Evaluation of Gamified TrainingASolomon Four-Group Analysis of the Impact of Gamification on Learning Outcomes
Gamification is the application of game elements to non-game contexts. The process of gamification has been found to improve engagement levels, motivate participation and improve outcomes of activities. The primary focus of Gamification research has been on understanding how it can improve the process of learning, especially in academics or education. The impact of gamification in the organizational context is still relatively unexplored. The current study attempts to provide evidence supporting the use of gamification in organizational training. The study adopted an experimental methodology and is set in the context of organizations in India. The findings suggest that potential learners responded more positively to the gamified module and the knowledge gained was also higher through the gamified module. The gamified module also resulted in higher learner motivation. Thus, the current study provide support for the Theory of Gamified Learning that proposes that Gamification would increase Learner Motivation and thereby improve Learner reaction to the training and increase Learning. 2021, Association for Educational Communications & Technology. -
Relationship Between Job Stress, Employee Engagement and Job Satisfaction: A Study Based on Women Managers in 4 and 5 star Hotels in India
Women account for a very small percentage of the employee population in Indian luxury hotels. While they have proved themselves as valuable assets, the average tenure of a woman in a managerial role in the sector is still around 2 to 4 years. The Government of India in its India Skills report has identified the sector as a focus area, in the drive to achieve better gender ratios. This study takes a small step towards understanding the factors that could influence the tenure of women in the hotel sector. The study examines the role of job stress in determining the levels of job satisfaction of women in the Indian hotel industry. The study also examines the mediating effect that employee engagement may have on the relation. The researchers have studied women in managerial roles in 4 and 5-star hotels, across India. The findings suggest that there is a strong negative correlation between job stress and job satisfaction and that this relationship is partially mediated by the presence of employee engagement. The findings are particularly important for the hospitality sector in India, as it struggles to retain its talented female employees. 2022 K. J. Somaiya Institute of Management. -
Synergizing Humanity and Technology: A Human-Machine Collaboration for Business Sustainability in Industry 5.0
In the context of Industry 5.0, this paper emphasizes the crucial role of human-machine collaboration for sustainable business practices. It explores the need for a people-centric approach, recognizing the significance of the human workforce alongside advanced technologies. The study investigates three influential theoriesActor-Network Theory (ANT), Activity Theory, and Socio-Technical Systems Theory (STS)proposing a novel Socio-Technical Interaction Network (STIN) model that synthesizes their strengths. The STIN model views systems as intricate networks of diverse actors, both human and non-human, acknowledging their agency and interactions within socio-technical environments. By incorporating elements from each theory, it prioritizes contextual analysis, considering socio-cultural and environmental influences on human-technology interactions. The STIN model aims to provide a holistic lens for interdisciplinary research and guide the design of technology-infused systems aligned with human needs and societal contexts. In conclusion, human-machine collaboration is deemed not just a technological necessity but a strategic imperative for organizations striving for long-term sustainability in Industry 5.0, fostering adaptability, innovation, and sustainable practices.

Employee experience, well-being and turnover intentions in the workplace
Purpose: This study aims to examine the role of employee experience in influencing employee well-being and turnover intentions within organizations. The mediating role of well-being will also be investigated, along with an exploration of whether these relationships differ across genders, specifically in the Indian corporate context. Design/methodology/approach: A descriptive, quantitative study was conducted using structured questionnaires to gather data from 111 employees in the Indian corporate sector. The study used a non-probability judgment sampling method. Data was analyzed through SPSS for descriptive and inferential statistics, and partial least squares was used to explore mediation and model fit. Findings: The study found a significant impact of employee experience on well-being, as well as a negative correlation between both employee experience and turnover intention and well-being and turnover intention. Well-being was found to partially mediate the relationship between employee experience and turnover intention. Gender-based analysis revealed no significant differences in the relationships between these variables for men and women. Originality/value: This research highlights the universal applicability of employee experience as a predictor of well-being and turnover intention, irrespective of gender. By establishing that gender does not moderate these relationships, this study provides new insights challenging traditional assumptions about gender disparities in workplace outcomes. 2024, Emerald Publishing Limited. -

Enhanced photocatalytic activity of La3+ doped bicrystalline titania prepared via combustion method for the degradation of cationic dye under solar illumination
La3+ doped TiO2 photocatalysts were successfully synthesized by combustion method in the presence of urea and were characterized by various physico-chemical techniques. Further, the photocatalytic performance of the synthesized catalysts was monitored by photocatalytic degradation of synthetic cationic dye-Methylene Blue (MB) under solar illumination. The bicrystalline phase of anatase and rutile was confirmed by X-ray diffraction analysis. Moreover, the transformation from anatase to rutile phase proceeds at a slower rate in the La3+ doped TiO2 catalysts. Effective separation of charge carriers, a synergistic effect in the bicrystalline framework of anatase and rutile, smaller crystallite size, and higher concentration of surface adsorbed hydroxyl groups helped these catalysts to show improved activity for the dye degradation.

Ceria doped titania nano particles: Synthesis and photocatalytic activity
Ceria (0.5, 1 and 2 mol%) doped titania nano catalysts were prepared by combustion synthesis method, using titanium isopropoxide as the starting material. The prepared catalysts were characterized by X-ray diffraction (XRD), Energy dispersive X-ray analysis (EDX), Scanning electron microscopy (SEM) and Infra red spectroscopy (FTIR). Total acidity of the prepared catalysts were determined by temperature programmed desorption of ammonia (TPD - NH3). XRD pattern of 1% ceria doped titania obtained by calcinations at 873 K indicated that the samples were crystalline with a mixture of anatase and rutile phase. No peaks corresponding to cerium oxide were observed XRD patterns indicating that the amount of cerium is negligible on the surface of titania catalyst. The photo catalytic activity was evaluated for the degradation of methylene blue (MB) under visible light irradiation. The degradation rates of MB on cerium doped TiO2 samples were higher than that of pure TiO2. The introduction of structural defects (cationic ceria dopant) into the titania crystal lattice leads to the change of band gap energy. As a result, the excitation energy is expanded from UV light of anatase TiO2 to visible light for ceria doped titania. 2016 Elsevier Ltd.
