Clan Culture in Organizational Leadership and Strategic Emphases: Expectations Among School Teachers in India
Understanding the current and preferred organizational culture among school teachers in India is a primary requirement, particularly when the National Educational Policy (NEP) is being implemented. Measuring the competing values using the Organizational Culture Assessment Instrument (OCAI) provides information about the dominant characteristics of the organizational culture and the school teachers' preferences. We surveyed school teachers and received 273 responses. Research revealed that clan culture is the overall current and preferred organizational culture type. Many of the results are not a surprise. However, we found that organizational leadership is currently in the hierarchy culture and strategic emphasis is on adhocracy, whereas teachers prefer a clan culture on these dimensions. Teachers expect school leaders to be the ones who facilitate the path to achieve, provide mentoring, and are instrumental in team building. They prefer a culture that provides for the development of human capital, promotes high trust and transparency among teachers, and offers an opportunity to participate in decision-making. This study is unique as it measures schools' organizational culture that has not been done earlier in the Indian context. The results suggest implications on the leadership practices and the strategic emphasis that need to change, in order to facilitate the implementation of the National Education Policy (NEP). 2022.

THE VICIOUS LOOP OF BODY SHAMING AND SELF-PROJECTION: AN EXPLORATIVE STUDY OF INDIAN YOUNG PEOPLE AGED 20-30 YEARS OLD
Background: Body shaming leads to much insecurity that is often overlooked. Its impact results in many ways, either in the form of some mental disorder, non-acceptance of oneself, low self-esteem, decreased life satisfaction, etc. The Media adds to it by portraying perceived perfectionism in terms of appearance which at times acts as a trigger to people already suffering or going through these. Purpose: The purpose of the study was to explore the psychological effects of body shaming on young people, and to analyze the role and impact of media in the portrayal of body image issues. Design/Methodology/Approach: A Semi-structured interview of 20 participants was carried forward (10 males & 10 females belonging). All Participants belonged to the age bracket of 20-30 years. Interpretative Phenomenological Analysis was conducted thereafter. Findings: All the participants mentioned that body shaming has affected their well-being and self-esteem and it led them to body shame others as well. It was also found that media has been marketing body image issues in many ways which created both positive and negative impacts. The following themes were generated based on analysis: age-appropriate body, rituals to fit in, marketing by accepting, after effects, the vicious loop, confusion to/and acceptance. Conclusion: The psychological impact of body shaming is often overlooked and that creates more damage. Similarly, the marketing of body image issues is so popular that often it is used in the form of humour. All of these experiences create a deep impact on people and lead them to the vicious loop of body shaming. 2022, RJ4All Publications. All rights reserved. -
Electro fabrication of molecularly imprinted sensor based on Pd nanoparticles decorated poly-(3 thiophene acetic acid) for progesterone detection
In recent years, scientific community has witnessed substantial interest in the design and engineering of electrodes as sensing platforms towards sensitive and selective detection of hormones. An electrochemical strategy for the detection of progesterone was proposed by generating a composite film comprising of palladium nanoparticles with 3-thiophene acetic acid (3-TAA) coupled with molecular imprinting technology. Progesterone molecule was employed as the template while generating molecular imprints by electropolymerization on the surface of the Carbon Fibre Paper (CFP) electrode. Electrochemical impedance spectroscopy (EIS) and cyclic voltammetry were used to analyse the various modified working electrodes (CV). Characterization methods included field emission scanning microscopy, energy dispersive X-ray spectrometry, optical profilometry, and X-ray photon electron spectroscopy. Pd nanoparticles resulted in enhanced sensitivity and molecular imprinting technology contributed to its specificity. Because of the molecular cavities created on the removal of the template molecule, Nyquist plots data showed that the MIP/Pd/CFP electrode had the lowest charge transfer resistance compared to other control electrodes. 2022 Elsevier Ltd -
Recent advances in functionalization of carbon nanosurface structures for electrochemical sensing applications: tuning and turning
Carbon nanomaterial has garnered interest in the research fraternity owing to the multiple advantages which includes its earth abundance, good electronic conductivity, excellent tolerance to acidic/alkaline media, and very good biocompatibility. Because of the above-mentioned advantages, they have found their way through applications in catalysis, sensing environmental remediation, and biological application. Heteroatom doping and organo-functionalization of carbon materials greatly extends the arsenal of these materials and their potential for a spectrum of application particularly in the field of electrochemical sensing. This review focusses on the creation and development in the design of electrochemical sensors based on the usage of doped and organo-functionalized carbon materials. Emphasis is given on the distinct properties and synergistic effects resulting from functionalization and doping. We hope that this review would throw light into the minds of researchers who would like to tune and turn their work, such that it promotes further activities in this particular field of research. 2021, Islamic Azad University. -
Molecularly Imprinted Scaffold Based on poly (3-aminobenzoic acid) for Electrochemical Sensing of Vitamin B6
Inadequate or excess consumption of Vitamin B6 (Vit B6) can have ill effects on the overall well-being of humans, thereby making it necessary to control their content and composition in the food we consume. A simple sensor is fabricated in this work for Vit B6 detection based on employing an electropolymerized molecularly imprinted polymer (MIP) of 3-amino benzoic acid. The poly (3- aminobenzoic acid) (P-(3ABA)) film was electrodeposited by potentiodynamic cycling of potential with and without Vit B6 (template) on carbon fiber paper electrode (CFP). The modified working electrodes were characterized by electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). Field emission scanning microscopy, Energy dispersive X-ray spectrometry, Fourier Transform Infrared spectroscopy, Optical profilometry and X-ray photon electron spectroscopy were used for characterization. Nyquist plots revealed least charge transfer resistance at MIP/CFP than other control electrodes due to the molecularly imprinted sites. Under the optimized experimental conditions the developed MIP sensor showed a linear range 0.6 ?M to 700 ?M, with a detection limit of 0.010 ?M. Also a value of the imprinting factor (? = 3.50) indicates very good selectivity of the prepared sensor towards Vit B6 detection over its structurally similar analogues in the analysis of real sample matrices. 2021 The Electrochemical Society ("ECS").

Biomass- or Biowaste-Derived Carbon Nanoparticles as Promising Materials for Electrochemical Sensing Applications
Modern human lifestyle incorporates the use of sensors to a great extent. Electrochemical sensors are the oldest and most commonly studied type of sensor with a wide commercial usage and numerous possibilities. Porous carbons are an important class of electrode materials and have a number of benefits compared to other materials in terms of sensor fabrications. Biomass pyrolysis and hydrothermal carbonization are important techniques to synthesize cost-effective, cheap, and more environmentally friendly porous carbon nanomaterials with higher electrocatalytic efficiency, selectivity, and sensitivity and better detection limits. The surface area of hierarchical porous architecture along with the graphitic nature of bio-derived carbon materials greatly affects the performance of electrochemical sensors. Numerous techniques are performed to improve the surface properties such as activation, doping, etc., in order to enhance the electrocatalytic behavior of working electrodes. The carbon materials discussed here are promising candidates as an effective alternative to many commercial electrochemical sensors. 2022 WILEY-VCH GmbH, Boschstra 12, 69469 Weinheim, Germany.

Label free electrochemical detection of stress hormone cortisol using sulphur doped graphitic carbon nitride on carbon fiber paper electrode
Sulphur doped graphitic carbon nitride (SGCN) was effectively prepared and comprehensively described. A straightforward synthetic process based on thermal condensation was reported for the synthesis of SGCN using thiourea as a precursor. Cyclic voltammetry (CV) and differential pulse voltammetry were used to evaluate the electrochemical performance of cortisol. SGCN sheets were used to boost the electro-catalytic activity, exhibiting very exceptional electrochemical behaviour towards cortisol. As a result, we obtained a broad linear response range of 0.1-100 ?M, as well as a comparatively low detection limit (15.8 10?8 M). Furthermore, the fabricated SGCN/CFP electrode shows excellent selectivity in the presence of a large number of possible interfering species. SGCN comprises (C with N and S) heteroatoms, which most likely would have led to a better current response towards cortisol detection. Furthermore, the structural defects that generate additional active sites on the surface of SGCN may enhance the quick electron transfer that occurs during the oxidation of cortisol. 2022 The Royal Society of Chemistry. -
Nanomaterial- Based Electrochemical Sensors for Vitamins and Hormones
Women and adolescent girls around the globe have fallen prey to, or rather have become vulnerable to, infections and poor health conditions due to the deficiencies caused by their deprivation of vitamins and proteins along with hormonal imbalance resulting in a snowballing effect causing declining well-being among women. The methods currently available in assessing vital hormones and vitamins are time-consuming and expensive, thereby making them inaccessible to economically weaker sections of society. The work carried out so far in determining and quantifying these biomolecules has mostly employed immunosensing techniques on screen-printed electrodes. Glassy carbon electrodes or carbon paste electrodes modified with metal nanoparticles, graphene, and various polymerized films are also being used for the sensing of these biomolecules. In this chapter, the authors navigate a path through, and give a concise outlook on, various nanomaterial-based electrodes and their comparative efficiency for electrochemical sensing of vitamins and hormones. 2023 selection and editorial matter, Anitha Varghese and Gurumurthy Hegde; individual chapters, the contributors. -

DeepBBBP: High Accuracy Blood-brain-barrier Permeability Prediction with a Mixed Deep Learning Model
Blood-brain-barrier permeability (BBBP) is an important property that is used to establish the drug-likeness of a molecule, as it establishes whether the molecule can cross the BBB when desired. It also eliminates those molecules which are not supposed to cross the barrier, as doing so would lead to toxicity. BBBP can be measured in vivo, in vitro or in silico. With the advent and subsequent rise of in silico methods for virtual drug screening, quite a bit of work has been done to predict this feature using statistical machine learning (ML) and deep learning (DL) based methods. In this work a mixed DL-based model, consisting of a Multi-layer Perceptron (MLP) and Convolutional Neural Network layers, has been paired with Mol2vec. Mol2vec is a convenient and unsupervised machine learning technique which produces high-dimensional vector representations of molecules and its molecular substructures. These succinct vector representations are utilized as inputs to the mixed DL model that is used for BBBP predictions. Several well-known benchmarks incorporating BBBP data have been used for supervised training and prediction by our mixed DL model which demonstrates superior results when compared to existing ML and DL techniques used for predicting BBBP. 2022 Wiley-VCH GmbH. -
Solvent polarity, structural and electronic properties with different solvents and biological studies of 3,3,5-triphenylfuran-2(3H)-one- cancers of the blood cells
The current work comprises synthesis, characterization and computational evaluation on 3,3,5-triphenylfuran-2(3H)-one with density functional theory (DFT) as the underlying principle. The theoretical optimized structure and corresponding geometrical parameters were obtained. Multiwfn 3. 8 was employed to conduct topological investigations such as R D G, E L F, L O L, and charge transfer analyses, which are used to identify the excited states, non-covalent interactions and important bonding regions in the molecule. Effect of solvents on the variation in molecular properties were studied with different polar solvents, with the IEFPCM model, as furanones interact with more polar solvents. The solvation studies were shown to impact on F M O, UV, M E P, and NLO analysis and thus between gas and solvent phases, a variation is observed in the properties under study. N B O studies were analysed to identify the natural bond orbitals within the molecule that contribute the maximum to the stabilization energy of the title compound. Pharmacological evaluation using readily available online tools that include SwissADME, Pre-ADMET, GUSAR, and ADMETLab 2.0 to determine the medicinal chemistry properties of the molecule was done. Furthermore, molecular docking onto chosen anticancer protein targets is performed utilising the softwares AutoDock Suite. PyMOL,and Discovery Studio Visualizer, is used to determine the best docked conformations that suggest potential capability of the compound to inhibit these proteins and protect the body from cancerous growths. 2022 Elsevier B.V. -
The odd one is Out: Voices from virtual classrooms
This article is a response to the online classrooms initiated from April 2020 onwards in schools across the country after the declaration of the lockdown. As classes went live in some parts of the country and several schools prepped towards the new medium, voices and experiences emerged from the field to throw light on the odds. The article collects the voices of students, educators and parents largely from the cities of Delhi and Bengaluru. The narratives are to be seen against the background of the critique of auto-modernism and emergent technology-intensive social institutions in the wake of COVID-19. This perspective pieces together the issues of infrastructure inadequacy in technology and the exclusiveness of pedagogy, and charts the inability of the marginalised sections in exercising the fundamental right to education. This article also highlights that internet classrooms are temporary make-shift arrangements. 2021 Economic and Political Weekly. All rights reserved. -
Framework for a smart E-Procurement system for ship building
The research aims to improve the shipbuilding process by reducing the time required for building a vessel through adoption of lean in the procurement management process. The research identifies the AS-IS process for procurement, uses Value Stream Mapping to identify different actions, identifies the root causes for administrative lead time with the help of fish bone diagram and proposes a framework for e-procurement system. It was found that lack of proper communication and visibility between the processes can increase the lead time for purchase order creation for different materials. The use of a smart e-procurement system can improve the visibility of the process across various departments and with the suppliers. This can improve the efficiency of the shipbuilding process, reducing the time required for manufacturing a vessel. 2024 by IGI Global. All rights reserved. -
Factors influencing student mentoring: Insights from higher education institutions
Mentoring has a close relationship to the word journey, symbolic of a goal-oriented process. Goal 4 of the Sustainable Development Goals (SDGs) stress on quality education and mentoring in educational institutions is a vehicle in this direction. Higher education is a crucial phase when students seek coaching and guidance for professional development. Higher Education Institutions (HEI) focusing on quality education assign mentors for students' academic and professional enhancement. The present study involving 92 participants describes the mentoring process followed in two social science courses of two different HEI by following a mixed-method and employing descriptive statistics and grounded theory. The emergent themes include continued communication channels between mentor and mentee, goals, duration, frequency, conflict mitigation, age and inclusion. These are structured as a model which is akin to the Rhodes Model of Youth Mentoring but more comprehensive and suited to the Indian context. 2021 SCMS Group of Educational Institutions.

Does ESG Integration Enhance Financial Performance in Emerging Economies? A Systematic Review of Brics
A growing wave of environmental and social problems is driving the world's focus on sustainability, and the UN's creation of the Sustainable Development Goals (SDGs) and ESG-focused investments are giving this movement a strong push. Today, investors consider ethical and moral principles coupled with monetary factors. ESG, which stands for Environmental, Social, and Governance, is a set of factors used to judge how well a company runs. These factors look at how the company protects the environment, treats its workers and society, and manages itself fairly and effectively. The present study is a systematic literature review of ESG and its influence on the firm financial performance of BRICS nations. The majority of the existing literature places focus on ESG in the developed world and this study aims to bridge this divide by focusing on Emerging economiesBRICS. The majority of the studies reveal a positive association between ESG and firm financial performance. The findings reveal the primary financial variables that affect ESG performance in BRICS countries such as firm size, debt ratios, weighted average cost of capital, return on equity (ROE), return on capital (ROC), Returns on Sales (ROS), Return on Assets (ROA), transparency levels, and financial leverage. Various theories such as Long-term gains, Institutional theory, Stakeholder theory, and Legitimacy Theory have laid the foundation for the research in the area. The review highlights the need for uniform ESG frameworks and enhanced disclosures to foster responsible investment practices in emerging economies like BRICS nations, providing valuable insights for companies, investors, and regulatory bodies.

Is ESG the Key to Stimulate Financial Performance? An Empirical Investigation
Environmental, Social, and Governance (ESG) principle is a critical framework for businesses and non-business entities. Recently, investors increasingly concentrate on the ethical impact of their investments in addition to financial rewards. The present study outlines links between a companys ESG practices and its financial performance. By means of performance comparison between the Nifty 100 ESG and Nifty 100 Indices within the Indian context, it issuggested that investing in ESG-adopting companies can lead to better financial performance. The study uses statistical analysis to compare the performance of both indices between 2018 and 2022. The analysis includes financial ratios, such as P/E ratio, ROA, ROE, and ROCE. The findings reveal a relatively modest connection between ESG and P/E ratio. The stronger negative correlations between ESG and key financial metrics (ROA, ROE, and ROCE), signifies a more robust trade-off between ESG focus and financial performance.

Electrochemical recognition of MMA-A biomarker for vitamin B12 deficiency based on ?-cyclodextrin self-assembled on polyaminothiazole
For the first time, the efficient electroreduction and identification of methyl methacrylate (MMA) was achieved using a carbon fiber paper (CFP) electrode modified with polyaminothiazole-?-cyclodextrin (PAT-?-CD). The recognition capabilities of the ?-CD/PAT/CFP and PAT/CFP electrodes were investigated using cyclic voltammetry, revealing the significant influence of ?-CD on the observed electroanalytical behaviour. Specifically, a PAT-?-CD modified CFP electrode was fabricated by electropolymerizing aminothiazole, serving as a substrate for ?-CD self-assembly through hydrogen bonding between the hydroxyl groups of ?-CD and the nitrogen atoms of the polyaminothiazole ring system. This as-prepared electrode exhibited a novel electrochemical method for the identification of MMA. Notably, the final ?-CD/PAT/CFP electrode demonstrated superior electrocatalytic activity towards MMA reduction under optimized conditions compared to bare CFP and other modified electrodes. This modified electrode displayed an extended linear concentration range of 10 nM to 270 nM and a low limit of detection (LOD) of 0.6 nM. Furthermore, the electrocatalyst demonstrated excellent stability, repeatability, and negligible interference from other species. Finally, the developed ?-CD/PAT/CFP electrode was successfully applied for the quantitative determination of MMA in human urine samples. 2025 The Royal Society of Chemistry. -
