Decoding Autonomy in Rohinton Mistry through Diasporic Encounters
No full textThrough diasporic cross cultural encounters, an individual is capable of asserting his personal autonomous self. The environment to which a person is exposed to influences the life experiences and behaviours. This autonomous self can in turn help the individual in asserting his self will and develop himself into a creative self determined person. By scrutinising Rohinton Mistry’s “Swimming Lessons”, it could be discerned how he has successfully portrayed a person caught in the diasporic space. Through a close reading of the text it could also be identified how the protagonist gets accustomed to the new culture and how he evolves into an autonomous body willing to see what is ‘inside’ having seen what is happening ‘outside’ his worldview. By employing the theories of personal autonomy, and diaspora, it could be stated that a migrant self can develop into a creative autonomous individual able to come out as an autonomous creative self

HOMO-LUMO analysis performed by B3LYP method at 6-311++G (d,p) basis set reveals charge transfer interactions in the molecule. Hirshfeld surface analysis and NCI plots were employed to identify the non-covalent interactions responsible for crystal packing. Second harmonic generation of the compound was investigated using urea as reference
Chromatographic methods for the detection, purification and separation of Dendrimers
No full textDendrimers have aroused scientific temper since their first hypothesis by Flory and later reported by Fréchet and co – workers. Properties such as pharmacodynamics and bio distribution of these unique polymers are dependent on their size and diffusion rates. Reverse Phase High Performance Liquid Chromatography (RP – HPLC) and Ultra High Pressure Liquid Chromatography (UPLC) are two unique methods used in the purification and quantification of various types of dendrimers. RP – HPLC is usually the primary method for usual sample analysis, being more rugged in comparison to various other forms of liquid chromatography. Columns for RP – HPLC and UPLC are non – polar, stable and reproducible. Though UP – HPLC offers less run time and increases sensitivity, there are associated problems with reduction in column life due to decreased particle size and high pressure. The present review serves to examine methodologies in the use of both these separation techniques in the analyses of dendrimers
Chemical Stability and Electrochemical Properties of Perovskite Based Composite Electrolytes with High Ionic Conductivity
No full textComposite electrolytes consisting of protonic conducting perovskite oxide Sr(Y0.08Zr0.92)O3-d and Sr(Gd0.1Ce0.9)O3-d (SYZS and SGDC) and alkaline carbonate (Li2CO3:Na2CO3, 1:1 molar ratio) were prepared through high energy milling followed by sintering techniques. The chemical and microstructural stability of these perovskite oxides with the mixed carbonates were studied by powder X-ray diffraction (XRD) and scanning electron microscopy (SEM) after reacting them at 690 °C for 1 h in air. The electrochemical performance of selected composites was evaluated using impedance spectroscopy in air. Among the two compositions, SrGdCeO3 shows degradation in contact with molten carbonates whereas SrYZrO3 is more stable. The corresponding composites have ionic conductivities (3.3x10-1 Scm-1 at 580 °C, in air) close to those reported for state-of-the-art ceria-based composite electrolytes. SrYZrO3+Li2CO3:Na2CO3 composites show chemical stability at operating temperatures in the order of 600 °C, standing as a potential candidate for intermediate temperature applications
Does Crypto Taxation Fuel Bitcoin Prices? An Event Study Approach
No full textSince their inception, cryptocurrencies and their associated markets have been notorious for their volatility, whether in terms of high volatility or illiquidity. Partly for those reasons, governments and regulators all over the world have tried to regulate those markets on a regular basis. In this study, it was evaluated to see if Bitcoin traders think market regulation is advantageous. The study evaluated the impact of regulatory news on Bitcoin taxes on cryptocurrency market returns in India using an event study technique, announced in the Union Budget. The results showed that the news of thirty percent taxation does result in any abnormal returns during the event window. It is clear from the study that the Indian taxation policy on virtual digital assets didn’t influenced the crypto market as well as Bitcoi
Biological Evaluation of a Novel Potentially Tridentate Schiff Base and its Selected Transition Metal(II) Complexes
No full textA Schiff base ligand was synthesized by the condensation of antipyrine-4-carboxaldehyde with 2-amino-3-carboxyethyl-4,5,6,7-tetrahydrobenzo[b]thiophene and its Co(II), Ni(II), Cu(II) and Zn(II) complexes were prepared by microwave assisted solvent free synthesis. The biological activity of the prepared ligand and the metal complexes was assessed by in-vitro testing of their effect on the growth of various strains of bacteria and fungi. A gel electrophoresis assay demonstrated the ability of the complexes to cleave the pUC19 DNA. The alpha amylase inhibitory activity of the ligand and the metal complexes were evaluated and found that metal complexes possess higher activity than the ligand
Infrastructure Development and Marginalisation: Perceptions Negotiated through Mass Media Coverage - A Study of Vizhinjam International Seaport Project, Kerala, India
No full textA quarter century experience of a paradigm shift to neo-liberal economic policies and the subsequent development agenda were instrumental in creating tangible growth as well as new forms of marginalisation and displacement in India. This dichotomy led to many studies which examined the nature of public responses to mass media coverage of various components pertaining to this larger issue. This study has focused on the Vizhinjam International Seaport Project of Kerala (a south Indian State) and the perceptions of the fishing community living there towards this project as negotiated through the mass media coverage. Consequently the media-driven perceptions among the fishing community and their real view about these issues or factors were analysed separately through a field study. It was observed that their perceptions about this massive infrastructural project were not primarily conditioned by the mass media coverage. It was revealed that, although media coverage was strident in portraying the project as an \u27imperative\u27 for development, it was not helpful in allaying the fears of displacement and marginalisation among the fisherfolk. Despite being exposed to the chances of embracing \u27modern lifestyles\u27 by migrating to jobs other than in the fishing sector, the community was not persuaded to do so. Thus the study points towards the critical necessity of engaging in a truly participatory communication with the primary stakeholders right from the formative stages of development programmes and projects
A study of India’s rural development programmes
No full textRural development has gained international attention, particularly among developing countries, and it is critical for a country like India. Rural development focuses on the development of rural economies that are suffering from severe poverty and effectively seeks to increase their production. It also emphasises the importance of addressing several critical concerns that impede village economies growth and improvement. The Indian government has announced a number of rural development projects. Housing is a big issue in rural India, as is the lack of infrastructure in villages and towns to connect communities via all-weather roads and the lack of employment prospects in villages. The government of India has announced the Pradhan Pmantri Awas Yojana Gramin (PMAY-G) Scheme to provide houses, the Pradhan Mantri Gram Sadak Yojana(PMGSY) scheme to build roads, and the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) to provide employment to rural people in this paper. These three programmes are critical to India’s rural development. According to the report, 44.54 lakh residence were built under the PMAY-G scheme during 2017-18, compared to a target of 1.00 crore houses by March 2019. In 2017-18, the speed of PMGSY road construction hit an eight-year high of 134 kilometres per day. Compared to an average of 73 kilometres from 2011 to 2014. During the financial year 2017-18, MGNREGA supplied employment to 5.12 crore households by producing more than 234.25 crore person days of wage employment encompassing 177 lakh jobs
VALUE-AT-RISK WITH TIME VARYING VOLATILITY AND ITS APPLICATION BASED ON EGARCH MODEL
No full textThis study examines the influence of the current global financial crisis on the market risk exposure of investments in the Indian stock market. Market risk is quantified using the value-at-risk method (VaR). This risk management metric, which financial organizations commonly use, determines the most significant loss that may occur over a specified trading time with a specified level of confidence. Due to the well-documented time-varying volatility of financial time series, standard techniques of calculating VaR frequently underestimate the magnitude of portfolio losses, particularly during periods of high volatility. We use anEGARCH formulation to enhance the volatility forecasts and hence the VaR estimations. VaR is then calculated many times during the out-of-sample period. The results indicate that this method of calculating VaR is more accurate at capturing the real impact of market risk across a range of volatility situations
TRIPLE BOTTOM LINE APPROACHES OF HOSPITALITY INDUSTRY IN INDIA
No full textIndian tourism and hospitality industry has emerged as one of the key drivers of growth among the service sectors in India. Hotels represent the largest segment of hospitality services in India. The impact of hotel industry on various sectors is estimated to be substantial and the growth of hospitality business depends on the expansion of the number and capacities of the hotel rooms. With the change in preference and behavior of customers, hotels have customized facilities and services to maximize efficiency and yield. “Hospitality with responsibility” is the present need and most hoteliers are begun to ‘green up’ their operations with triple bottom line (TBL) approaches. It not only focuses on the economic value of the hotel but also the contribution towards environment and society. This paper is an attempt to understand the initiatives of hospitality firms in India which set their goals based on profit, planet and people as they realized the tourist’s commitment toward sustainable development
