Determinants of corporate dividend policy in India: A dynamic panel data analysis
The present study empirically examines the determinants of dividend policy of National Stock Exchange (NSE) listed firms in India, using dynamic panel data model for the sample of 95 NSE listed firms with continuous dividend payments from 2012/2013 to 2017/2018. The empirical results reveal that profitability, liquidity, leverage, risk, size of the firm and inflation are the major determinants of dividend policy of selected NSE listed firms in India. Findings deduced from empirical evidence bears testimony to the fact that profitability, liquidity, size of the firm and inflation have significant negative impact on dividend policy of the selected NSE firms covered by the study. These findings seem contradictory to the expected outcome contained in the existing literature on the Indian context. The risk variable tends to have negative and significant impact, which is line with the existing literature. Besides, the lagged dividend, investment opportunities, taxation and yield curve do not play significant role in determining the dividend policy. 2020 Allied Business Academies. -

The Transnational Influence of Energy on Cultural Practices : A Study on Kuttanad Wetland Systems
The phenomenon of the extensive Kerala-Gulf migrations has exerted a significant influence on the socio-economic development and local cultures of the state. This study newlineinvestigates the evolving cultural perceptions and practices in the region with the rapid migrations, employing the conceptual framework of energy as a guiding lens. Energy is viewed as the fundamental and material fuel communities engage with to shape and organise their cultures. By situating the research in the field of Energy Humanities, it interrogates the role of shifting energy regimes and transnational energy systems in specifically shaping the local community s relation with the land and environment. The study focuses on Kuttanad, a wetland-based region in Kerala, historically known for its intense paddy cultivation and rice production. Wetland environments play a significant role in environmental sustainability by sustaining the carbon cycle and exist as complex biodiverse ecosystems. The study employs a mixed-method qualitative approach by combining ethnography and textual analysis that form the primary data for analysis. The selected novel Moustache (2020) by S. Hareesh translated by Jayashree Kalathil serves as the primary text. In ethnography, methods like semi-structured interviews, participant observation, and focus-group discussions were utilised to directly obtain insights from the newlineparticipants perspective. The collected data was systematically coded and analysed to newlineexplore an underlying energy unconscious within the culture. The findings present early agrarian Kuttanad as an organic-based energy regime with flow and animate forms as newlineprimary sources of energy that act as agency and effect in shaping local cultures. It newlinehighlights the overlooked aspect of energy s influence on the social dynamics, power newlinestructures, and everyday values and practices of local cultures. -

A statistical approach to study anatomical changes of pink guava cultivar (Psidium guajava L. cv Arka Kiran) during its ripening at the room temperature storage
The ripening of climacteric fruit like guava is a complex process that is highly coordinated with its cellular backbone. In the present study, we combined microscopy, spectrophotometry, and statistical analysis to evaluate the anatomical changes in the pink variety of guava during five ripening stages (pre-ripe, ripe, color-turn, half over-ripe, and over-ripe) during its storage at room temperature (282 C). The cholorophyll content of the peel, as determined by the measurement of chlorophyll a, b, and total chlorophyll, showed a significant decrease during the maturation process (4.05, 4.53, and 8.62 ?g/cm2, respectively, in the pre-ripe stage to not detectable in the over-ripe stage). Gradual loss of integrity of the fruit pulp (pericarp) from the preserved bee-hive structure to cell mass was also monitored by studying the cellular anatomy with brightfield and scanning electron microscopy. The epidermal thickness and width of the cortical parenchyma cells revealed statistical differences from the initial pre-ripe stage to the final full-ripe stage. Finally, based on the cellular dimensions, multivariate analysis using PCA (Principal Component Analysis) tool grouped the stages into three clusters, namely, pre-ripe: ripe, color-turn: half-over ripe, and over-ripe stages. In conclusion, this study provided significant insights into cultivar-specific anatomical changes in guava fruit, with potential for future research to develop variants with longer post-harvest storage life. 2024 The Author(s) -
Unravelling Post-harvest Ripening Metabolomics of a New White Variety Guava Fruit (Cv Arka Mridula) with Special Emphasis on Phenolics and Corresponding Antioxidants
The phenolic, antioxidant and metabolic profiling of a new white variety guava fruit Arka Mridula (AM) was performed during its storage at theroom temperature (28 2 C). The comparative profiles were generated at three ripening stages (pre-ripe, ripe and over-ripe) of the fruit. Generally, a steady decrease of the phenolic and antioxidant content from the pre-ripe to the ripe stage and a subsequent increase from the ripe to over-ripe stage was observed. Further, a powerful correlation between the phenolic content and antioxidant principles was noted through the principal component analysis. We could identify 53 compounds for the hydro-methanolic fruit extract through LC and GC-MS aided metabolic analysis, and the identified compounds were dominated by phenolics (~ 44%). The statistical analysis revealed that phytochemicals catechin, myricitrin, myricetin, kaempferol glycosides and n-hexadecanoic acid contributed significantly towards the ripening process of AM, during the storage. The present study is expected to provide important insight into the ripening biochemistry of AM. Subsequently, it may help in the future development of metabolically stable guava cultivars with extended post-harvest shelf life. Graphical Abstract: (Figure presented.)

Evaluation of phenolic and antioxidant profiles of pink Guava peel (Psidium guajava L. cv Arka kiran) during fruit ripening and its in silico Anti SARS-CoV-2 property
Guava (Psidium guajava L.) is a highly nutritious and economically important fruit. Although fruit peel is generally regarded as a waste, researchers believe that the peel of the guava is rich in bioactive constituents, even higher than the fruit's flesh. The present study aimed to estimate phenolic content (total phenolic and total flavonoid) and assess antioxidant properties of guava fruit peel (pink variety, cv Arka kiran) by 2,2-di (4-tert-octylphenyl)-1-picryl-hydrazyl (DPPH), 2,2?-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid (ABTS) and Ferric Reducing Antioxidant Potential (FRAP) assays at five different ripening stages (stage 1 to 5). The TPC and TFC assays were performed by Folin-Ciocalteu and aluminium chloride (AlCl3) methods, respectively. The molecular docking experiment between the major phenolic of guava peel, Catechin and the spike protein of SARS-CoV-2 was performed by the Dockthor online server. Results showed that the peel had high phenolic (highest TPC and TFC, 7307.3 mg gallic acid equivalent/g dry weight [DW] and 433.9 mg quercetin equivalent/g DW, respectively) and antioxidant values (highest DPPH, ABTS and FRAP values 4784.8, 206.6 and 2451 mg ascorbic acid equivalent/g DW, respectively) throughout all stages, although there was a gradual decline in the activity at the later stages. Furthermore, it was found that catechin had a strong binding affinity (-7.591 kcal mol-1) with the spike protein, in silico when compared with the control drug ceftazidime (-7.250 kcal mol-1). The overall outcome of our experiemnts revealed that guava peel could be explored for future pharmacological applications through in vivo studies, and the green mixed with the yellow stage of ripening is optimum for such studies.

Collaboration between gram panchayat and women self-help groups on rural development in karnataka
Mahatma Gandhi said, Indiaand#8223;s development relays on development in rural India. To see a developed India, we must develop villages in India. India is trying to improve the living standard of rural people since Independence. Government, Non-Government Organizations, Voluntary Groups, and many individuals are making continuous efforts for decades to improve rural condition. There is a positive change and growth, but the achieved results are not satisfactory in relation to need, the available resources, opportunities, and the efforts made. What are the root causes of failures? Are there necessary coordination and collaboration among the development efforts to optimize the fruits and minimize the loss of human and material resources? Gram Panchayat Institutions and Self-Help Groups by women are two of major efforts which became very powerful means to empower and develop rural people. The Constitution (73rd Amendment) Act, 1992 became a land-mark by establishing Panchayat Raj Institutions (PRI) in Indiaand#8223;s effort for rural development and reaching out the democracy to grass-root level by newlineforming Panchayat Raj Institutions with three tier system. The Reservation policy of 72nd newlineAmendment Act was another turning point in empowering effort. NGOs initiated Self-Help newlineGroups in India in early 1990s and later Government also supported and promoted the newlineinitiative. Will the Collaboration between the Gram Panchayat Institutions and Women SelfHelp Groups enhance development of rural area through higher level of Community newlineParticipation is the research question here. newlineThere are many writings, studies and evaluations on Gram Panchayat Institutions and SelfHelp Groups by women to assess the existing condition, and to make the efforts more efficient and effective towards rural empowerment and development. Still, studies on impact of collaboration between Gram Panchayat and Women Self-Help Groups on rural newlinedevelopment are missing. -
