Effect of Professional Development Program in Enhancing Leadership Skills of In-Service Teachers in Diverse Domains of Practice
In alignment with the recent National Education Policy and National Professional Standards for Teachers in India, which promote the Continuous Professional Development of Teachers (CPD), the present study developed, implemented, and evaluated a Teacher Professional Development Program on Leadership (TPDP-L) for developing and enhancing teacher leadership skills in six domains of practice. The participants (n = 54) of the study (20 from government schools, 18 from aided schools, and 16 from unaided schools) were selected through purposive sampling, ensuring diverse representation. The study employed a quasi-experimental, single-group pretest-posttest design, utilizing the Teacher Leadership Scale, a self-assessment questionnaire, to assess the programs impact. The result shows a large effect size and statistically significant differences in all leadership domains. The studys promising results suggest that TPDP-L is an evidence-based CPD program for developing and enhancing leadership skills among in-service schoolteachers. The studys findings evidence practical implications for implementing educational policies. 2025 Taylor & Francis Group, LLC. -
Effect of Premixing Process on the Uniform Distribution of Nano hBN and Carbon Fiber Reinforcements in AA7050 Matrix
In Aluminium metal matrix composites, achieving a homogeneous dispersion of reinforcements remains a significant challenge, especially when mixing fibrous and nanoscale reinforcements. The effect of the premixing procedure on the homogeneous dispersion of carbon fiber (CF) and nano hexagonal boron nitride (hBN) reinforcements in AA7050 matrix is studied in this work. Before composites are prepared, a multi-stage process for premixing is used, which consists of ultra-sonication, magnetic stirring, and mechanical mixing in order to minimize particle clustering. This also improves the wetting between the reinforcement and the matrix. Field emission scanning electron microscope (FESEM) was used to characterize the premixed powders to assess agglomeration behaviour, interfacial integrity, and dispersion uniformity. Due to the premixing process, better densification of nearly 95.2% and enhancement of 33.3% of micro-hardness are reported for 0.25 wt.% CF and 0.5 wt.% hBN addition. The results reveal that after the premixing process, particle dispersion was improved, leading to high-quality composites in the subsequent sintering process. The premixing process offers a better way to disperse the nano reinforcement particles in the production of aluminium metal matrix nanocomposites, which directly influences the properties of the composites. -
Effect of post annealing on DC magnetron sputtered tungsten oxide (WO3) thin films for smartwindow applications
Tungsten oxide (WO3) thin films were deposited on Fluorine Doped Tin Oxide (FTO) and Corning Glass (CG) glass substrate by DC magnetron sputtering. The annealing temperature was varied to study its effect on surface morphology, structural, electrochromic (EC), and optical properties and these are investigated by Scanning Electron Microscope (SEM), X-ray Diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), Raman spectroscopy, Cyclic voltammetry, and ultraviolet (UV) spectroscopy. From SEM analysis WO3 thin films annealed at 27 C, 100 C, 200 C, and 300 C were shown to crack free after that cracked film was observed for 400 C. From the XRD investigation that the WO3 thin films annealed at 27 C, 100 C, 200 C, and 300 C were amorphous and crystallized at 400 C. The optical band gap (Eg) of WO3 films was decreased from 2.98 eV to 2.30 eV with an increase in annealed temperature. The coloration efficiency (CE) was observed at 51.26 cm2/C at 300 C and 35.06 cm2/C at 400 C and the lowest diffusion coefficient was observed at 5.86 10?10 cm2/s at 400 C. On coloring efficiency, which can be very important in electrochromic (EC) applications, post-annealing has been seen to have a strong influence. 2023 Elsevier B.V. -

Effect of Phonological and Phonetic Interventions on Proficiency in English Pronunciation and Oral Reading
The current research aimed to know the effect of phonological and phonetic interventions in enhancing proficiency in English pronunciation and oral reading among teacher trainees. This study was of single-group pretest and posttest intervention designs. The sample size was selected through a stratified random sampling technique from teacher training colleges in Bengaluru. Two hundred and seven teacher trainees with L1 proficiency were chosen proportionately from Bangalore strata and orientated. Participants (N = 32) enrolled voluntarily in the intervention program for 20 hr. Intervention modules on phonology and phonetics were developed by the researcher and a segmental approach was adopted to teach modules in 20 sessions. After every session, the participants were allowed to record the modules in Audacity, a multiaudio recorder application. The recorded modules were interpreted, and scores were determined on number of intelligible words pronounced by the participants. Further, it was validated by the experts to authenticate the determined scores. The researcher applied oscillographic and observation methods to analyze the participants' progress in pronunciation and oral reading proficiency levels during the experiment. The Wilcoxon signed-rank test was used to test the impact of intervention between the pretest and posttest (before and after intervention). The hypotheses testing revealed the difference between preintervention and postintervention scores in phonological and phonetic awareness and oral reading among teacher trainees, and the sig. value is less than 0.05 across all the attributes. This study insists that English phonology and phonetics must be a crucial part of the English language teaching (ELT) curriculum and highlights that teachers must be able to spot the most appropriate pronunciation teaching and train the students of English as a foreign language (EFL) with intricates of intelligible pronunciation. This study navigates the need for language proficiency among teacher trainees, especially in English pronunciation and oral reading, and substantiates the evidence that effective intervention and teachers' knowledge of pronunciation enhance proficiency levels in pronunciation and oral reading among teacher trainees. Finally, it hopes that B.Ed colleges and teacher educators will be beckoned to use technology-integrated intervention to teach phonology and phonetics. 2024 Diwakar Prahaladaiah and Kennedy Andrew Thomas. -

The current research aimed to determine the effect of phonological and phonetic intervention in enhancing proficiency in English pronunciation and oral reading among teacher trainees. The study adopted a single-group pre and post-test intervention design. The researcher developed intervention modules on phonology and phonetics, and a segmental approach was adopted to teach individual sounds. The research design was executed in five stages: experts' opinions on the need for such a study, a preliminary study to find the need for the study, the development of intervention modules and validation of the modules, the pilot study to check the reliability of the tools, and the main study. The researcher applied Oscillo-graphic and observation methods to analyse and test the participants' pronunciation and oral reading progress during the experiment. Communicative Language Learning (CLL) and Audiolingual approaches were adopted to teach individual sounds to participants. The National Assessment of Educational Progress Scale for Reading and Pronunciation (NAEP 2012) was adopted to measure the scores. The other instruments, i.e., audio-to-test phonetic transcription software and Audacity recording software, were used in the experiment to record and analyse the audio clips. The experiment was conducted on n=104 teacher trainees of Bengaluru, India. The current study targeted teacher trainees/ B Ed college students of English method as a population. The population of teacher trainees was 1470 English methods from Bangalore north, south, and central. Further, the sample size for the main study was 104, and it was selected through a stratified random sampling technique. The assessment tools overall reliability (Cronbach Alpha value) (NAEP) on Pronunciation and Oral reading is 0.873. The data normality was tested with the Kolmogorov-Smirnov test. The data EFFECT OF PHONOLOGICAL AND PHONETIC INTERVENTION was normally distributed. Hence, the data was not normally distributed; the non- parametric tests were used to test the hypotheses. The hypotheses testing on phonological and phonetic awareness revealed the difference between pre- intervention and post-intervention scores in phonological and phonemic awareness and oral reading among teacher trainees, the sig. Value is less than 0.05 across all the attributes. The Wilcoxon signed rank test revealed the scores after the intervention, a post-test with a statistically significant value of 0.001. The post-test score, which was after the intervention, is significantly higher. The values across all the attributes related to oral reading and pronunciation with a statistically significant value of 0.001. The other hypotheses testing on gender, age, and qualification, the Mann-Whitney test, and Kruskal Wallis were used, and the results were not statistically significant. The statistical test was used to test the progressive improvement of teacher trainees during the intervention, and it was statistically significant with 0.001 across all the attributes. The data analysis revealed a positive impact of intervention at the post-test on teacher trainees. The study has navigated the need for language proficiency among teacher trainees, especially in English pronunciation and oral reading. The study substantiates the evidence that effective intervention and teachers' knowledge of pronunciation would enhance proficiency levels in pronunciation and oral reading among teacher trainees. The study also hopes that Policy Makers, Universities, B.Ed. Colleges and teacher educators will be beckoned to use technology-integrated intervention to teach phonology and phonetics. -

The paper focuses on the synthesis and characterization of cobalt oxide nanoparticles synthesized under different alkaline pH of the precursor solution by hydrothermal method. Cubic spinel Co3O4 crystallites were observed by X-ray diffraction pattern (XRD) and Raman spectrum. The crystallite size decreases as the pH value increases. The absorption spectrum exhibited two broad bands which are in good agreement with the cobalt oxide band structure. The change in bandgap was observed with pH of the precursor solution in agreement with size effects. Photoluminescence (PL) spectra consist of a broad emission with different peaks which are due to point defects. 2022 -
Effect of personality, psychological capital, institutional support on job satisfaction and affective commitment among private school teachers on South Karnataka
A teacher's personality traits are important to create and maintain a
classroom learning environment. The behaviour of Teachers depends on the characteristics of the personality. There have been many pieces of research based on the positive aspects of teachers' behaviour through enhancing some psychological states which are based on the positive institutional behaviour. This particular research has its focus on the positive strengths of the teachers, and this construct has an essential influence on job satisfaction. Hence, a satisfied and engaged teacher is very much necessary to strengthen the competitive student base of every School.

There have been many pieces of research based on the positive aspects of teachers' behaviour through enhancing some psychological states which are based on the positive institutional behaviour. This particular research has its focus on the positive strengths of the teachers, and this construct has an essential influence on job satisfaction. Hence, a satisfied and engaged teacher is very much necessary to strengthen the competitive student base of every School. To explore the fact, the researcher has chosen the constructs such as Personality, Positive psychological capital, Institutional factors (Perceived Institutional support, Work-life policies, Work autonomy), Job satisfaction factors, and Affective commitment to study the impact of the Big five dimensions of personality on job satisfaction and affective commitment of private school teachers in South Karnataka and to investigate the impact of psychological capital on job satisfaction and affective commitment of teachers. The study also attempts to understand the influence of Institutional factors (perceived Institutional support, work-life policies, and work autonomy) on job satisfaction and affective commitment. Also, the study explores the influence of job satisfaction on the outcome factors namely affective commitment among private school teachers. The study used a descriptive research design, and it is observed that the total number of districts in south Karnataka is fifteen. The researcher selected four private schools from each district randomly with the help of the private school list used as a sampling frame. The total sample size for the study estimated were 477 teachers working in private schools. The study has analysed the data using appropriate statistical tools such as (i) frequency analysis, (ii) Factor analysis, (iii) ANOVA with post hoc (v) Regression analysis. The study concludes that when the private school teachers personalities such as extraversion, agreeableness, conscientiousness, and openness to experience which will tend to significantly influence Job satisfaction among teachers working in the private schools of South Karnataka. Similarly, private school teachers Psychological capital like resilience, self-efficacy, optimism, and hope which tend to influence job satisfaction at their work significantly. This study also concludes that private school teachers to be given proper work-life balance and work autonomy by the school management, which will significantly influence job satisfaction among the teachers at work. Also, private school teachers who possess personalities such as extraversion, agreeableness, conscientiousness, and openness to experience significantly influence the teacher's affective commitment. The study also reveals that the private school teachers have Psychological capital like resilience, Self-efficacy, Hope, and Optimism, which tend to significantly influence their affective commitment which will reflect towards their respective institution. If the private institution gave the school teachers proper work-life balance and work autonomy, then they tend to influence their affective commitment significantly. Also, it is concluded that the affective commitment of teachers significantly influences the job satisfaction level of school teachers. This implies that the school management can enhance the level of teachers' commitment to their schools by creating a more conducive and more satisfying environment in the workplace. Accordingly, schools can decide on pay and other monetary incentives. However, they can enhance teachers' job satisfaction by creating better training and development opportunities, improving leadership and management support, promoting accountability, and involving teachers in decision-making made at the school level. Another important finding of this study is the observed positive relationships between scores of job satisfaction and organizational commitment. Some of these findings contradict the existing literature in these fields; others are inconsistent with the prevailing literature. -

Effect of partial pressure of oxygen, target current, and annealing on DC sputtered tungsten oxide (WO3) thin films for electrochromic applications
Tungsten oxide (WO3) thin films were prepared on Corning (CG) and Fluorine doped tin oxide (FTO) glass substrates at partial pressure of oxygen (pO2) 4 10?2 Pa and 8 10?2 Pa using DC magnetron sputtering (DCMs). In this work, we have varied the deposition parameters like pO2, target currents, and temperature. At pO2 4 10?2 Pa and 8 10?2 Pa samples were deposited at target currents of 50 mA and 100 mA, the maintained growth conditions are RT (substrate temperature 28 C), Pre annealed (substrate temperature 400 C), and Post annealed (annealing temperature 400 C). The samples were systematically characterized for vibrational, structural, optical, and Electrochromic (EC) properties by using Raman, XRD, Uv-Vis spectrometer, and Electrochemical analyzer respectively. XRD analysis reveals that RT-deposited samples show amorphous nature and pre & post-annealed samples show a crystalline nature for both pO2. Optical transmittance was higher at RT-deposited samples at 50 mA (94% & 92%) and lower at 100 mA (87% & 85%) at the wavelength of 600 nm for both pO2. From CV analysis higher cathodic peak current density was observed in RT-deposited samples at 50 mA (?6.49 mAcm?2 & -13.80 mAcm?2) and lower at 100 mA (?5.25 mAcm?2 & -12.88 mAcm?2) for both pO2. The diffusion coefficient was observed at a higher target current at 100 mA (1.06 10?7 cm2/s & 9.20 10?8 cm2/s). For annealed samples optical and EC properties were decreased for both pO2. 2023 Elsevier B.V. -
Effect of Oxygen Flow Rate, Post-annealing Temperature, and Different Electrolyte Concentrations on WO3 Thin Films Deposited by DC Magnetron Sputtering For Electrochromic Applications
In this work, tungsten oxide (WO3) films were deposited at room temperature and annealed for 2h at 400C. The electrochromic and electrochemical properties were studied for two different electrolytes. The films were deposited at different oxygen flow rates of 2, 4, and 6 standard cubic centimeters per minute (SCCM). X-ray diffraction analysis revealed structural characterization of amorphous and crystalline phases. UV-visible spectroscopy optical transmittance revealed 91% transmittance, and energy-dispersive x-ray spectroscopy (EDS) analysis revealed the absence of impurities and the presence of W and O. An electrochemical analyzer was used to characterize the deposited and annealed WO3 films immersed in the two different electrolyte solutions (H2SO4 and LiClO4 with oxygen flow rates ranging from 2 SCCM to 6 SCCM). It was found that the H2SO4 electrolyte of an annealed WO3 thin film at 2 SCCM demonstrated high coloring efficiency of 50.18cm2/C, and the LiClO4 electrolyte of an annealed WO3 thin film at 4 SCCM demonstrated high coloring efficiency of 20.06cm2/C.

Effect of Organizational Culture during Crises on adoption of virtual classrooms: An extension of UTAUT model
This study aims to understand the impact of organizational culture in the context of obligatory adoption of a virtual classroom (VC) during the COVID pandemic. The academic crisis created by the pandemic resulted in obligatory adoption of VCs, without being mandated by top management. Organizational culture was tested by this crisis, and thus created a unique opportunity to examine adoption. This research examines Organizational Culture during Crises (OCC) as an antecedent to the Unified Theory of Acceptance and Use of Technology (UTAUT) model to evaluate the factors that determine the intention to adopt a virtual classroom across multiple disciplines by the faculty of a reputed Indian university. Data collected from a sample of 353 respondents was analyzed to test the research model using Structural Equation Modeling (SEM). The findings of the study reveal that OCC plays a positive and significant role in determining the intention of faculties to adopt a virtual classroom. We also found that OCC also significantly influences performance expectancy, effort expectancy, facilitating conditions and social influence. The results imply proper framing of policies by top management of Higher Education Institutions (HEI) for the smooth adoption of virtual classrooms by faculty when confronted by crises. 2021 The Author(s).

Effect of nonlinear thermal radiation on MHD boundary layer flow and melting heat transfer of micro-polar fluid over a stretching surface with fluid particles suspension
A comprehensive numerical study is conducted to investigate effect of nonlinear thermal radiation on MHD boundary layer flow and melting heat transfer of micro-polar fluid over a stretching surface with fluid particles suspension. Using suitable transformations, the governing equations of the problem are transformed in to a set of coupled nonlinear ordinary differential equations and then they are solved numerically using the Runge-Kutta-Fehlberg method with the help of shooting technique. Authentication of the current method is proved by having compared with established results with limiting solution. The impact of the various stimulating parameters on the flow and heat transfer is analyzed and deliberated through plotted graphs in detail. We found that the velocity, angular velocity and temperature fields increase with an increase in the melting process of the stretching sheet. Also it is visualize that the shear stress factor is lower for micropolar fluids as compared to Newtonian fluids, which may be beneficial in flow and heat control of polymeric processing. 2017 Trans Tech Publications, Switzerland. -
Effect of nonlinear thermal radiation on double-diffusive mixed convection boundary layer flow of viscoelastic nanofluid over a stretching sheet
Background: The present exploration deliberates the effect of nonlinear thermal radiation on double diffusive free convective boundary layer flow of a viscoelastic nanofluid over a stretching sheet. Fluid is assumed to be electrically conducting in the presence of applied magnetic field. In this model, the Brownian motion and thermophoresis are classified as the main mechanisms which are responsible for the enhancement of convection features of the nanofluid. Entire different concept of nonlinear thermal radiation is utilized in the heat transfer process. Methods: Appropriate similarity transformations reduce the nonlinear partial differential system to ordinary differential system which is then solved numerically by using the RungeKuttaFehlberg method with the help of shooting technique. Validation of the current method is proved by having compared with the preexisting results with limiting solution. Results: The effect of pertinent parameters on the velocity, temperature, solute concentration and nano particles concentration profiles are depicted graphically with some relevant discussion and tabulated result. Conclusions: It is found that the effect of nanoparticle volume fraction and nonlinear thermal radiation stabilizes the thermal boundary layer growth. Also it was found that as the Brownian motion parameter increases, the local Nusselt number decreases, while the local friction factor coefficient and local Sherwood number increase.

Effect of Non-inertial Acceleration on BrinkmanBard Convection in Water-Copper Nanoliquid-Saturated Porous Enclosures
In the present paper we have considered rotating porous tall, square and shallow enclosures heated from below. Linear and non-linear analyses are made using a minimal representation by Fourier trigonometric series. The study is done for realistic boundary condition. Thermophysical properties of water-copper nanoliquid as a function of properties of water as base liquid, copper as nanoparticle and 30% glass fiber reinforced polycarbonate as porous medium are obtained from either phenomenological laws or mixture theory. Non-existence of oscillatory convection is discussed. The range for the existence of unicellular convection is mentioned. The effects of Brinkman number (?), porous parameter (?2), aspect ratio (A) and volume fraction (?) in the presence of rotation on the onset of convection and heat transfer are studied and illustrated graphically. The analytically intractable Lorenz model is derived and transformed into the tractable GinzburgLandau equation using the multiscales method. The definition of Ozoe heat transfer parameter is introduced to discuss the rate of heat transfer enhancement or reduction. It is observed that Ta, ? and ?2 have stabilizing effect on the system and thereby leading to diminished heat transfer whereas A and ? have destabilizing effect on the system and thereby leading to increased heat transfer. Among the three enclosures considered in the study enhanced heat transfer takes place in tall enclosure followed by square and shallow enclosures respectively. It is further observed that presence of nanoparticles advances the onset of convection and enhances the heat transfer. The results of the paper are compared with previous existing results in the absence of rotation and the good agreement is found between them. 2021, The Author(s), under exclusive licence to Springer Nature India Private Limited. -
