During their respective missions, the spacecraft Voyager and Cassini measured several Saturn magnetosphere parameters at different radial distances. As a result of information gathered throughout the journey, Voyager 1 discovered hot and cold electron distribution components, number density, and energy in the 6-18 Rs range. Observations made by Voyager of intensity fluctuations in the 20-30 keV range show electrons are situated in the resonance spectrum's high energy tail. Plasma waves in the magnetosphere can be used to locate Saturn's inner magnetosphere's plasma clusters, which are controlled by Saturn's spin. Electromagnetic electron cyclotron (EMEC) wave ring distribution function has been investigated. Kinetic and linear approaches have been used to study electromagnetic cyclotron (EMEC) wave propagation. EMEC waves' stability can be assessed by analyzing the dispersion relation's effect on the ring distribution function. The primary goal of this study is to determine the impact of the magnetosphere parameters which is observed by Cassini. The magnetosphere of Saturn has also been observed. When the plasma parameters are increased as the distribution index, the growth/damping rate increases until the magnetic field model affects the magnetic field at equator, as can be seen in the graphs. We discuss the outputs of our model in the context of measurements made in situ by the Cassini spacecraft.

The elements that impact the dynamics and collaborations of waves and particles in the magnetosphere of planets have been considered here. Saturn’s internal magnetosphere is determined by substantiated instabilities and discovered to be an exceptional zone of wave activity. Interchanged instability is found to be one of the responsible events in view of temperature anisotropy and energization processes of magnetospheric species. The generated active ions alongside electrons that constitute the populations of highly magnetized planets like Saturn’s ring electron current are taken into consideration in the current framework. The previous and similar method of characteristics and the perturbed distribution function have been used to derive dispersion relation. In incorporating this investigation, the characteristics of electromagnetic ion cyclotron wave (EMIC) waves are determined by the composition of ions in plasmas through which the waves propagate. The effect of ring distribution illustrates non-monotonous description on growth rate (GR) depending upon plasma parameters picked out. Observations made by Cassini found appropriate for modern study, have been applied to the Kronian magnetosphere. Using Maxwellian ring distribution function of ions and detailed mathematical formulation, an expression for dispersion relation as well as GR and real frequency (RF) are evaluated. Analysis of plasma parameters shows that, proliferating EMIC waves are not developed much when propagation is parallelly aligned with magnetosphere as compared to waves propagating in oblique direction. GR for the oblique case, is influenced by temperature anisotropy as well as by alternating current (AC) frequency, whereas it is much affected only by AC frequency for parallel propagating waves.

The present work aims to extend Meyer, Shankar, & Berry (2017)’s work on antecedents of consumer willingness to pay (WTP). This research paper investigates the role of antecedents such as autonomy, quality variability, complementarity, overall quality and bundle quality, for the traditional bundles (i.e., bundles consisting of either goods or services). The paper uses the choice-based conjoint methodology to measure consumer’s WTP for the traditional bundles in an experimental vignette set-up. The study uses four different types of traditional bundles as consumer stimuli to analyze the factors mentioned above. The results indicate that autonomy, overall bundle quality, and quality variability were significant in influencing the consumer’s WTP. Consumer WTP has been widely used as a factor to derive the optimal prices of the bundles in the literature. For a retailer selling a traditional bundle, it is imperative to have an understanding of consumer WTP and also make an attempt to increase it by offering high customer value. By knowing the factors determining the antecedents of consumer WTP, one can reap higher benefits monetarily as well as in the form of increased customer satisfaction. The paper also challenges the view that it is difficult to influence the consumer’s WTP. It advances the understanding of the factors which influence the consumer WTP for the widely used traditional bundles.

MARKETING RESEARCH FOR MANAGERS: REVISITED

Shivan Sanjay Patel,Shivendra Kumar Pandey,Dheeraj Sharma,Rama Shankar Yadav 글로벌지식마케팅경영학회 2018 Global Marketing Conference Vol.2018 No.07

The present paper is an addition to the relevance debate in marketing literature. Research is said to be ‘relevant,’ if it leads to change, alteration or validation of how managers think, talk or act. However, the majority of the literature on relevance debate talks about the decline in relevance, yet no study has scientifically measured it. The present study uses content analysis to analyze the trends in different types of relevance across three different eras of marketing eras (i.e., commoditization, generalization and post-debate era). We also conducted a second study to check the relative importance of different types of relevance to the managers using Analytic Hierarchy Process (AHP). The results reveal a U-shaped curve of the relevance across these different eras. They also reveal the influence of the relevance debate on the research conducted by academicians. Out of the eight types of managerial relevance identified, “Forecasts” was ranked the highest, followed by “Rhetoric devices” and “Uncovering causal relationships.” Finally, the study also presents a view for an academician to shape his/her research concerning the current needs of the industry.
