Construction and Validation of Indian Consumer Ethnocentrism Scale: The Ice-Scale

Globalization has unlocked and exposed domestic and overseas marketers to superior market opportunities. Additionally, it presents consumers worldwide with a vast number of local and foreign brand choices. Indian consumers, also now, have a broader choice of merchandise at their disposal as economic liberalization and privatization along with globalization have reduced the barriers to trade. In such a setting, the concept of consumer ethnocentrism can deliver deep insights about the preference of consumers toward domestic merchandise. The study aims to develop the Indian Consumer Ethnocentrism Scale (ICE-Scale) and validate the same. Data are collected using a structured questionnaire from urban and rural regions. The study constructed the Indian Consumer Ethnocentrism Scale (ICE-Scale), explored its dimensionality on a sample of 450 respondents, and validated the scale with another sample of 450 using exploratory factor analysis. It was established that the ICE-Scale encompasses two dimensions, namely, protective ethnocentrism and patriotic ethnocentrism. Additionally, the validity testing for the proposed scale and both the constructs were conducted through confirmatory factor analysis. The study advances the existing pool of information in the field of international economics, consumer psychology and global marketing. It also assists domestic producers to get an improved understanding of consumers’ ethnocentric tendencies which in turn would assist them in choosing superior marketing strategies and boosting their sales. The study will not only deliver certain social and policymaking insights to the domestic firms and government but also to the foreign firms functioning or planning to operate in India

Characterization of Eclipsing Binary System EPIC 211982753

We present the physical parameters of an eclipsing binary system EPIC 211982753 derived through photometric and radial velocity data modeling. We make use of photometric data from NASA's K2 mission, ASAS-SN, and 1.3-m Devasthal Fast Optical Telescope (DFOT) while spectroscopic data have been acquired from the HERMES spectrograph at the 1.2-m Mercator telescope. The linear ephemeris for the system is updated using the K2 mission data. The synthetic light curve and radial velocity curves are generated with the help of eclipsing binary modeling package PHOEBE 1.0. The masses of primary and secondary components are determined as 1.64 $\pm$0.02 and 1.55 $\pm$0.01 $M_{\odot}$, respectively. The radius for primary and secondary components are estimated as 1.73 $\pm$0.02 and 1.47 $\pm$0.02 $R_{\odot}$, respectively. The distance of the system is calculated as 238 $\pm$ 4 pc. The eclipsing binary is found to be a total eclipsing system with a high mass ratio of q=0.94.Comment: Proceeding paper of the 3rd Belgo-Indian Network for Astronomy and Astrophysics (BINA) workshop, Accepted for publication in the Bulletin of Li\`{e}ge Royal Society of Science

Peeping into recent star formation history of the Magellanic Clouds

Here, we study the distribution of Fundamental-mode Cepheids in the Magellanic Cloud as a function of their positions and ages using the data from the OGLE~IV survey. Age of the Cepheids are determined through well known period - age relations for the LMC and SMC Cepheids which are used to understand the star formation scenario in the Magellanic Cloud. The age distributions of the Cepheids in LMC and SMC show peak around $155^{+45}_{-35}$ Myr and $224^{+51}_{-42}$ Myr, respectively. This indicates that a major star formation event took place in the Magellanic Cloud at about 200\,Myr ago. It is believed that this event might have been triggered by a close encounter between the two components of the Magellanic Cloud or due to a possible tidal interaction between the Magellanic Cloud and Milky Way galaxy during one of its pericentric passages round the Milky Way. Cepheids are found to be asymmetrically distributed in both the LMC and SMC. A high-density clumpy structure is found to be located towards eastern side of the LMC and south-west direction of the SMC from their respective galactic centres.Comment: Accepted to the Journal of Astrophysics & Astronomy, contribution to the proceedings of "Star formation studies in the context of NIR instruments on 3.6-m DOT
