Some properties of star-perfect graphs
For a finite simple graph G = (V, E), ?s(G) denotes the minimum number of induced stars contained in G such that the union of their vertex sets is V (G), and ?s(G) denotes the maximum number of vertices in G such that no two are contained in the same induced star of G. We call the graph G star-perfect if ?s(H) = ?s(H), for every induced subgraph H of G. We prove here that no cycle in a star-perfect graph has crossing chords and star-perfect graphs are planar. Also we present a few properties of star perfect graphs. 2026 Azarbaijan Shahid Madani University. -

Unveiling Future Trends in Employer Branding: Systematic Review and Bibliometric Analysis
Employer branding, an emerging area in Human Resource Management (HRM), has gained significant importance. Despite its importance, the literature on employer branding remains fragmented due to the absence of a comprehensive review that consolidates the intellectual structure of the field. This study addresses the existing knowledge gap by conducting a systematic literature review accompanied by bibliometric analysis utilizing performance analysis and science mapping through the Tableau software package. Through a comprehensive review of 27 articles, this study reveals the key branding elements, top journals, contributing countries, industries, citation trends, sample statistics, theoretical contribution, and six key themes (i.e., Employer branding attributes, sustainable employer branding, employee-centric employer branding, social media employer branding, recruitment strategies, HRM practices of employer branding) that characterize the body of the employer branding. Finally, the study has identified an integrative framework and set the direction for future research. It offers actionable recommendations for HR practitioners, emphasizing technology integration in employer branding initiatives and incorporating sustainable practices to enhance organizational attractiveness. This research contributes to a deeper understanding of the concept of employer branding. It provides valuable guidance for organizations seeking to navigate and optimize their employer branding strategies for the future. (2025), (Regional Inform. Center for Sci. and Technol.).

Role of Individualistic and Collectivistic Orientations in the Happy Life of Kharwar Adivasi Community
Following globalization, westernized cultural values, ideas, and practices have rapidly spread. Cultures are in flux, and indigenous communities are not free from the influence of the outside world. In this research, we investigated how the psychological tendencies of indigenous communities might be affected by such socio-cultural changes in a predominantly collectivist nation. A community-based study was conducted with 150 Kharwar Adivasi individuals residing in 10 villages of Naugarh block, Chandauli, Uttar Pradesh. The participants, aged 25-50 years, were given the measures of Individualism-Collectivism Orientations and Happy Life. Using an exploratory factor analysis, a five-factor structure emerged, explaining 57% of the variance in happy life. The results indicated that 59% of the sample had a collectivistic orientation. Individuals with a collectivistic orientation fared better in overall happiness and its sub-domains than individuals with an individualistic orientation. It is suggested that even though there is a gradual increase in individualism, for the Adivasi community, happiness is still enhanced by tendencies of interdependence. The findings have important implications for understanding the happiness of the under-researched Adivasi population. (2025), (School of Management Sciences). All rights reserved. -
THE CONFLICT CATALYST: IHL'S ROLE WHEN CLIMATE CHANGE TRIGGERS DISPLACEMENT
The escalating climate crisis is profoundly reshaping global human mobility, forcing millions to abandon their homes due to both sudden-onset disasters and insidious slow-onset environmental degradation. This paper examines how international humanitarian law (IHL) and climate-induced displacement are related, particularly when armed conflict intensifies or intersects with the consequences of climate change. Despite the informal usage of the term climate refugee, there is a significant protection gap because the 1951 Refugee Convention does not give it a legal designation. While IHL is primarily designed to regulate armed conflict and protect its victims, this research argues that its principles and provisions become indirectly, yet crucially, relevant when climate change acts as a threat multiplier, intensifying existing conflicts or creating new fragilities that lead to displacement. Through a qualitative legal analysis complemented by three diverse case studies, the Sunderbans (India and Bangladesh), the Lake Chad Basin, and Somalia/Horn of Africa. The paper aims to critically analyse the applicability and limitations of International Humanitarian Law in addressing climate-induced displacement, particularly in contexts where climate change acts as a threat multiplier for armed conflict. Through a case-based legal analysis, the article seeks to demonstrate how existing legal frameworks fall short of providing adequate protection for climate-displaced persons and to situate IHL within a broader matrix of human rights, migration, and climate governance regimes. 2025 Brawijaya Law Journal. -
AeroGlan: A Smart and Sustainable Plant Species Estimator For Organic And Localized Air Filtering
Introduction: Human health is significantly compromised by air pollution, especially by local air quality. The majority of our society spends their lives in a confined geographical location, which if subjected to air pollution can expose them to long-term air contamination. It is also possible that poor air quality can pose serious health risks, especially to susceptible individuals thereby impacting their lifestyle. Air quality can be improved with appropriate plantation, but they are underutilized. Various air purification devices have been developed in response to the ever-increasing air pollution level. Methods: However, artificial means of air purification are not very viable in terms of cost, accessibility to society, and reliable tools to purify air. This research integrates traditional solutions with modern technology to counter air purification by selectively using plant species and placing them in desired locations suitable for urban settings. The study aims to measure the constituents of various air pollutants spanning across regions to identify and accumulate pollution data using IoT-based smart devices, remit, and feed this information to cloud-based storage for further processing. In addition, advanced predictive intelligence is utilized to determine the plant species that can suffice the need for air purification through organic means in a given geographical zone resulting in enhancement of Air Quality (AQ), with minimal cost, prolonged shelf life, future proof and non-detrimental consequences. Results: Implementation outcome gives a promising outcome. Accurate readings of various air pollutants are aggregated. Suitable trees are identified to tackle these pollutants and their absorbing capacity is determined. Various predictive methods are employed and the random forest model recorded the best results. The sensory units of the model successfully captured the pollutant data and any major fluctuations were reported. The prediction pipeline recorded a mean precision, recall, and f-score value of about 0.95, 0.92, and 0.94 respectively while the mean accuracy of 0.965 was also noted. The observed training and validation accuracy with our model were 0.96 and 0.93 respectively. Conclusion: Hence, the proposed AeroGlan model may be locally applied as an air pollutants monitoring device and also to suggest suitable plant species required to counter air contamination in that locality. 2025, Bentham Science Publishers -
Associations Between Early Life Adversity, Moral Development, and Psychopathology in Children and Adolescents: A Cross-Sectional Study
Introduction: Moral psychological development is shaped by socio-cultural and neurobiological factors, with the formation of conscience central to this process. Early Adverse Childhood Experiences (ACEs) have been linked to delays in moral development and increased risk of psychiatric disorders. This study examined how adversity affects conscience functioning, specifically the association between Psychopathological Interference (PI) and delays in Conscience Stages (CS) compared to youth raised in relative advantage. Methods: We analyzed 125 conscience-sensitive psychiatric interviews with youth admitted to a Psychiatric Residential Treatment Facility (PRTF). CS scores were compared with expected stages from community youth, using the Conscience Development Quotient (CDQ = CS attained CS expected 100). PI was rated on a Likert scale, incorporating full psychiatric evaluations, behavioral ratings, and DSM diagnoses. Multiple regression models examined the associations between CDQ, PI, and Clinical Global Assessment of Functioning (CGAF) scores, controlling for six covariates. Results: Participants (mean age, 14.2 years; 59% male, 41% female) exhibited significantly greater distress signals across conscience domains compared to community youth. No differences emerged by age at the onset of ACE. However, lower CDQ was associated with higher PI, earlier ACE onset, DSM Axis II disorders, and lower CGAF. Legal history and ACE count were not significant predictors. The model explained 22.7% of the variance in CDQ (p = 0.00018). Discussion: Findings highlight CDQ as a sensitive measure of developmental impact, beyond simply identifying red flags, consistent with prior ACE research. Retrospective design may limit sensitivity to ACE characteristics. Conclusion: Systematic conscience-sensitive interviewing, attuned to cultural and developmental contexts, may enhance clinical assessment of moral functioning. 2025, Bentham Science Publishers -
Assessing the Impact of E-learning through Usage and Preference of E-resources
Aims: Any electronic device that delivers a collection of data, whether it be text referring to full text databases, electronic journals, photographs, other multimedia goods, or quantitative, visualizations, or time-based, is referred to as an electronic resource. These could be transmitted over the internet, tape, CD-ROM, tablets, smartphones, smart watches or another medium, these are now the basis of e-learning. Online searching has made it possible to get patent information more quickly, affordably, and conveniently than the traditional manual or CD-ROM based searching method. The ability to create and distribute documents in electronic form is now made possible by a number of established procedures and standards. So, in order to address the current problems, librarians are utilizing new media, particularly electronic resources, in their collection expansion makes the documentation of users better. As we can see, utilizing online resources is important in the modern world for a multitude of purposes. Because of this, it's important to understand the preferences, motives and usage of various e- resources used by students who use online learning. The aim of the present research paper was to examine the impact of e-resources using its usage and reading preferences. In this study, reasons such as time saving, more information, and busy schedule at college are considered. Methodology: Primary data was gathered from 250 students from Mumbai and Navi Mumbai who are using e-resources through the pre-structured questionnaire. The responses collected were recorded using the SPSS software for data analysis. In order to examine the link between causes, preferences, and the use of e-resources, a theoretical construct was developed grounded on a few assumptions. Statistical techniques like the chi-square test were used and data analysis was done using SPSS version 20 to examine the proposed construct. When doing the data analysis, the demographic profile, objectives, and hypothesis were all taken into consideration. Results: The average for each component that is time saving, more informative, and busy schedule at college was computed and was determined as 0.004, 0.004, and 0.000, correspondingly, for time saving, more informative content, and busy college schedule. As all of these values for all of the preferences under consideration are less than 0.05, it is clear that there is a connection between the usage of electronic resources and their underlying reasons and preferences. Conclusion: Hence, there is a substantial correlation between the reasons for using electronic resources and the different reading preferences, as well as between the two. Only three reasons namely time saving, more informative, and busy schedule at college are considered during this study. Data collection is done from Mumbai and Navi Mumbai region only. 2025 Bentham Science Publishers. -
Hybrid Deep Learning Framework for Continuous Blood Glucose Monitoring and Gestational Diabetes Risk Prediction
Gestational diabetes mellitus (GDM) affects almost 10%-12% of pregnancies worldwide, threatening maternal and fetal life. Continuous glucose monitoring (CGM) forms the backbone of managing GDM, and the current methodologies largely disregard physiological and behavioral factors, thereby greatly reducing accuracy and clinical interpretability. Methods: A hybrid deep learning framework was developed by fusing CGM with multi-sensing modality data, including heart rate, activity levels, sleep patterns, and dietary intake. For data preprocessing, Kalman filtering was applied for temporal alignment, adaptive normalization provided outlier handling and imputation, while the CNN-BiLSTM backbone with attention was harnessed for feature extraction. A Multi-Task Attention Fusion Network (MTAFN) was used to predict glucose values and classify GDM risk simultaneously, while SHAP and dynamic smoothing contributed to interpretability sets. Results: The framework was validated on an extended OhioT1DM dataset with adaptations for pregnancy. It reached a glucose prediction RMSE of 9.8 mg/dL and a GDM risk classification accuracy of 93%. Compared to competitive approaches, the present solution attained a 25% better accuracy on interpretability and an improvement in sensitivity and specificity of about 4-6% across various physiological conditions. Discussion: The use of multi-sensing data increased prediction robustness by capturing complex physiological dependencies. The SHAP-based interpretability justified the predictions through a physiological lens. With an attention mechanism for feature weighting, it was possible to identify crucial variables like meal intake and nighttime variability in the workflow sets. Conclusion: The hybrid framework proposed here is reliable for clinically interpretable continuous glucose monitoring and GDM risk predictions. Its application with high reliability can lead to integrating it within clinical protocols for real-time maternal care sets. 2026, The Author(s).

Harary Spectra and Energy of Certain Classes of Graphs
Aims: To investigate the H-eigenvalues and H-energy of various types of graphs, including k-fold graphs, strong k-fold graphs, and extended bipartite double graphs and establish relationships between the H-energy of k-fold and strong k-fold graphs and the H-energy of the original graph G, we explore the connection between the H-energy of extended bipartite double graphs and their ordinary energy and find the graphs that share equienergetic properties with respect to both the ordinary and Harary matrices. Background: The H-eigenvalues of a graph G are the eigenvalues of its Harary matrix H(G). The H-energy {Formula Presented} of a graph, G is the sum of the absolute values of its H-eigenvalues. Two connected graphs are said to be H-equienergetic if they have equal H-energies. They are said to A-equienergetic if they have equal A-energies. Adjacency and Harary matrices have applications in chemistry, such as finding total electron energy, quantitative structure-property relationship (QSPR), etc. Objectives: We determined the H-spectra of k-fold graphs, strong k-fold graphs and extended bipartite double graphs and established connections between the H-energy of different types of graphs and their original graph G for investigating the relationship between the H-energy of extended bipartite double graphs and their ordinary energy and the graphs that share equienergetic properties with respect to both the adjacency and Harary matrices. Methods: Spectral algebraic techniques are used to calculate the H-eigenvalues and H-energy for each type of graph and compare the H-energies of different graphs to identify the equienergetic properties and derive relationships between the H-energy of extended double cover graphs and their ordinary energy. Results: We determined the H-spectra of k-fold graphs, strong k-fold graphs and extended bipartite double graphs and established relationships between the H-energy of k-fold and strong k-fold graphs and the H-energy of the original graph G. Then, we explored the connection between the H-energy of extended bipartite double graphs and their ordinary energy and presented graphs demonstrating equienergetic properties concerning both adjacency and Harary matrices. Conclusion: The study provides insights into the H-eigenvalues, H-energy and equienergetic properties of various types of graphs. The established relationships and connections contribute to a deeper understanding of graph spectra and energy properties and the findings enhance the theoretical framework for analyzing equienergetic graphs and their spectral properties. Scope: Possible extensions of this research could include investigating additional types of graphs and exploring further explicit connections between different graph energies and spectral properties. Harary matrices are distance-based matrices, which can model distances between atoms in molecular structures and could be useful in organic synthesis to predict how molecular structures behave. 2025, Bentham Science Publishers -
Optimizing Functional Feed for Growth and Pathogen Resistance in Oreochromis niloticus using Fermented Seaweeds: A Comprehensive Approach Through Solid State Fermentation and Oxidative Stress Response
The study aimed to explore the potential of seaweeds Sargassum wightii and Gracilaria corticate fermented using Bacillus subtilis MN960600 (CK4). Fermented seaweeds showed enhanced antioxidant activity in DPPH assays. A second-order model known as Box-Behnken was used to create an optimized quadratic design for fermentation parameters enhancing protein, reducing sugars, and lipid yields. This optimized feed demonstrated significant growth improvement of 18 to 20 % in Oreochromis niloticus when compared to commercial feed and a 35 to 40% higher growth in fermented and non-fermented feed groups. Additionally, fish fed formulated seaweeds exhibited resilience to Vibrio harveyi and Aeromonas hydrophila pathogen stress. Additionally, the study highlighted the ability of the formulated seaweed in reduction of oxidative stress caused by pathogens Vibrio harveyi and Aeromonas hydrophila in Oreochromis niloticus. The study emphasized the potential use of seaweeds and probiotic bacteria as a sustainable aquafeed. 2025, Egyptian Society for the Development of Fisheries and Human Health. All rights reserved. -
A Qualitative Investigation of Adversities Experienced by Non-Alcoholic Adult Children of Alcoholics (ACOAs) in an Indigenous Community
This study explores the distinctive adversities encountered by non-alcoholic adult children of alcoholics (ACOAs) within the Mizo indigenous culture. Despite the abundance of literature on the adverse consequences of ACOAs, there is a dearth of global literature on the unique lived experiences of adversity among non-alcoholic ACOAs. Analysis of 13 in-depth interviews using the grounded theory approach identified that non-alcoholic ACOAs experienced a multitude of adversities across cognitive, affective, behavioral, and somatic domains. These adversities manifested as challenges in sustaining attention, lack of proficiency in problem-solving, distorted beliefs and negative emotions concerning relationships, skewed attachment styles, difficulty in managing oneself and adhering to rules, flawed relationship praxis, and somatic complaints such as fatigue, heightened psychomotor activity, and various aches and pains. These findings emphasize that parental alcohol misuse has lasting impacts on non-alcoholic ACOAs. Tailored early intervention and support programs are necessary to address these challenges. 2025, Institute for Human Rehabilitation. All rights reserved. -
Impact of organizational culture traits on employee intention to stay in the IT services sector: An empirical analysis
Employee retention poses a significant challenge in the Indian IT services sector, where frequent turnover leads to the loss of organizational knowledge and reduced productivity. This study assesses the impact of organizational culture on employees intention to stay in Indian-origin IT services companies in Bengaluru. We used Denisons Organizational Culture Model to measure culture across four dimensions, namely involvement, consistency, adaptability, and mission, and the Michigan Organizational Assessment Questionnaire to measure intention to stay. Using purposive sampling, we collected data from 384 employees of major Indian-origin IT firms between July 2023 and March 2024. Data were analyzed using factor analysis, linear regression, and Hayess PROCESS macro in SPSS 20.0. The results indicate that organizational culture has a significant and positive impact on employees intention to stay (? = 0.286, p < .001), accounting for 8.2% of the variance (R2 = 0.082). Path analysis confirms a strong positive effect (effect size = 0.486, 95% CI [0.322, 0.650], p < .001). The factor analysis demonstrates that stronger cultural dimensions especially empowerment, coordination and integration, organizational learning, and goals and objectives enhance employee retention in IT services firms. The study recommends that HR policies integrate cultural development to strengthen employee commitment and retention. Future studies should explore additional job and organizational factors that influence employee loyalty. Silpa Mary John, Smita Kavatekar, 2025. -
The impact of unconventional US monetary policy shock on emerging bond markets: A comprehensive assessment of global transmission channels
Extensive research has been conducted on the global effects of the US unconventional monetary policy shock on capital flows in emerging markets. However, there is limited empirical evidence on the transmission channels of capital flows in emerging bond markets. This study examines it by analysing capital flows across 45 emerging bond markets from 2009 to 2023. Contemporaneous shock transmission is examined using the contemporaneous impact matrix, and dynamic shock transmission is assessed using the impulse response function of the structural vector autoregression (SVAR) model. All variables in this study are standardised to account for differences in scale within the model. The pairwise correlation coeffcient matrix indicates that multicollinearity is not a concern for parameter estimates in this model. The ADF-Fisher Chi-square unit root test result reveals that all variables are stationary in this model. The contemporaneous coeffcient matrix results indicate that changes in the US term spread serve as the contemporaneous transmission channel through which US Treasury bond purchase and US MBS purchase shocks positively affect capital flows in emerging bond markets. The impulse response function indicates that changes in the global financial cycle serve as a dynamic transmission channel through which US MBS purchase shocks affect capital flows in emerging bond markets. Moreover, changes in the US mortgage spread serve as the dynamic transmission channel through which US Treasury bond purchases and US MBS purchases affect capital flows in emerging bond markets.

Do institutional quality and capital account openness affect capital flow? Evidence from Asian bond markets
Capital inflow into local bond markets helps countries with infrastructure financing, funding fiscal deficit, enhancing bond market liquidity, and diversifying investment portfolios globally. This study aims to assess the impact of institutional quality and capital account openness on capital inflow into Asian local bond markets for the period 20022023. For reflecting Asian bond markets, seven countries, namely, China, Malaysia, South Korea, Japan, the Philippines, Indonesia, and Thailand, have been considered. The rule of law, regulatory quality, control of corruption, voice & accountability, political stability, and government effectiveness indices are the various proxies considered in this study to measure the different aspects of institutional quality. Further, the Chinn-Ito index is employed to measure capital account openness. Fixed effect, random effect, and pooled data ordinary least squares are employed as different forms of panel data estimation methods in this study. Moreover, Breusch-Pagan LM and Hausman tests are performed to select the most efficient estimation method. This study reveals that the rule of law, regulatory quality, and control of corruption have a positive influence on capital inflow at a 5% significance level and political stability at a 1% significance level. In contrast, capital account openness has a negative impact at a 1% significance level. However, neither voice & accountability nor government effectiveness have a significant influence over capital inflow. These findings suggest improving the rule of law and regulatory quality, creating policies for political stability, stringent acts against corruption, and controlling capital account openness to encourage capital inflow into local bond markets.

ESG or financial METRICS? What Retail Investors Really Look for in Decision-making
With the increasing global emphasis on responsible investing, this study explores the tradeoff between ESG and traditional financial metrics in shaping the investment decisions of retail investors in India. A within-subject experimental design was employed at Christ University, India, involving an initial sample of 75 participants, with 55 completing all three experiment rounds. The sample respondents evaluated masked stock profiles across three rounds, where updated financial and ESG information on masked stock was provided at each round. The results indicate that though ESG metrics are getting attention among retail investors, financial metrics are still the main determining factor for investment. It was found that ROE (52 responses), 3-year CAGR Net Profit (36 responses), and P/E ratios (48 responses) are the most influencing factors to make investment decisions. Similarly, ESG factors (Governance, Environmental, and Sustainability scores) are also frequently mentioned, with 74 citations. Retail investors mainly consider profitability and view ESG as risk-mitigating or neutralizing factors. While evaluating the ESG factors, retailers mainly look at the firms environmental concerns, followed by governance and social factors. This result contrasts with the previous studies in this domain, where the literature emphasized governance factors more than environmental factors. These results highlight the integration of ESG elements, as retail investors remain with favorable returns and sacrifice sustainability. Further, this study spots the need for better and quantifiable ESG performance reports to consider alternative data comparable to financial data for better investment decisions.

Consumer willingness to adopt digital coupons in post-demonetization and COVID-19 in India
This study aims to examine the factors influencing consumers willingness to adopt digital coupons in India. It focuses on the impact of two major events: demonetization in 2016 and the COVID-19 pandemic. Together, these events have caused a shift toward digital payments and digital coupons, changing consumer behavior in favor of digital solutions. This study specifically focuses on consumers in Jaipur, both urban and rural, to capture the unique dynamics of this geographical region. In this study, 110 respondents from different demographic groups were given a structured questionnaire. 12 respondents were selected for in-depth qualitative interviews to learn more about the factors that promote and hinder the use of digital coupons. Quantitative data analysis is conducted using SmartPLS 4 software, and the qualitative interview data are analyzed thematically. The regression analysis reveals that convenience and perceived value drives the use of digital coupons, with 75% of respondents reporting their adoption. The findings bring into perspective how the digital consumer landscape of India is evolving and what role incentives play in digital marketing in driving consumer preference and shaping the long-term feasibility of the strategy. The conclusion reinforces that the use of digital incentives for consumers will be influential in choices and underlines the feasibility of digital approaches in the new consumer environment in India.

IN SEMICONDUCTOR MEDIA CAUSED BY DYNAMIC LOADING THROUGH MEMORY EFFECTS AND NONLOCAL FRAMEWORKS
We investigate a novel meticulous heat transfer model to capture the photo-thermal-elastic interactions efficiently inside a nonlocalized semiconductor material affected from a dynamic thermal loading. For the purpose of apprehending memory and nonlocal effects during complex diffusion processes inside the semiconductor, the Atangana-Baleanu fractional derivative is established on the linearized coupled thermoelastic theory which involves thermal displacement gradient and temperature gradient among the constitutive variables. Laplace transform methodology is acquired for solving the problem. Later on, a suitable algorithm of numerical inversion of the Laplace transform is employed for achieving the computational results in physical domain. As per the graphical results, conclusions about the influences of significant parameters such as fractional parameter, photo-generated carrier life-span and the velocity of dynamic heat source on the dimensionless physical fields like temperature, displacement, stress and carrier density are constructed. Further, the utility of the current advanced heat transfer model is established by comparing the graphical results of physical fields under the current heat transfer theory with the old developed theories of heat transfer models having two phase lags and single phase lag parameter. All the graphical results are evaluated against distinct values of depth of the semiconductor media. We believe that this fine study will support researchers for obtaining promising and optimum results of real world problems where the photo-thermal effects inside the semiconductor are taken into account. 2026 The Authors, under license to MSP (Mathematical Sciences Publishers). -
Microencapsulated spirulina fortified yoghurt - An insight into physicochemical and sensory properties
Yoghurt is a widely consumed dairy product having good nutritional and functional properties. Incorporation of spirulina can enhance its health benefits due to its rich protein and antioxidant activity. However, direct addition affects sensory attributes, leading to reduced consumer acceptance. This study evaluates the impact of microencapsulated Spirulina-fortified yoghurt (ME-SP yoghurt) (treatment) on its physicochemical, microbiological and sensory properties, comparing it with plain yogurt as the negative control and Spirulina-incorporated yoghurt (without encapsulation) as the positive control. Results indicated that spirulina incorporation increased protein content in both positive control and treatment, but negatively influenced sensory acceptance in treatment due to colour and flavour changes. Microencapsulation effectively masked undesirable sensory characteristics while preserving nutritional benefits and an increase in protein content by 4.05%. More quantity of spirulina (1%) could be added to yoghurt when we used encapsulated spirulina than spirulina without encapsulation (0.5%). Textural analysis showed improved viscosity and stability in the microencapsulated sample than PC and NC. Microbiological analysis confirmed the probiotic viability in all samples within the acceptable range, based on the Food Safety and Standards Authority of India (FSSAI) and Codex Alimentarius standards for fermented dairy products. Sensory evaluation revealed that microencapsulation significantly enhanced flavour (7.9) compared to direct spirulina addition (6.96). This study concludes that microencapsulation is a viable technique to enhance the functional properties of spirulina-enriched yoghurt while maintaining its sensory appeal. 2025 Indian Council of Agricultural Research. -
Reflexive Praxis in University Classrooms in India: A Case Study
This article presents the case study of a university teacher's journey focusing on struggles he faced in the personal and professional space during his teaching career that shaped his pedagogic practices. Bourdieu's structural parameters and Engstr's (1987) theory of expansive learning provided analytical concepts, including reflexivity, to study the pedagogical praxis of this teacher. The analysis of data collected using the biographical narrative interviewing method, classroom observation, and autobiographical writings of the teacher reveals that as he questions his social positioning, academic "field," and intellectual bias, he experiences conflicts and tensions that arise from several disruptions resulting in pain and frustrations at one level and at another level shaping his desire and the ability to engage critically and historically with the processes and outcomes of personal and pedagogic interrogations. He realizes that there is no "A" algorithm for developing reflexivity. It takes a lifetime for a teacher to build a reflexive praxis. 2025 Common Ground Research Networks. All rights reserved.
