Does imagination compensate for the need for touch in 360-virtual shopping?

The inability to touch products is a fundamental shortcoming in online shopping because humans typically use the sense of touch to evaluate the utilitarian product functionality and to obtain hedonic sensory enjoyment, which the instrumental and autotelic need for touch capture. This study of 900 consumers looks at the interplay between need for touch and imagination to study how imagination compensates for the lack of touch when consumers shop in a 360-virtual store. The study finds that while telepresence of a 360-virtual store improves consumer attitudes toward virtual shopping, the need for hedonic sensory enjoyment – autotelic need for touch – significantly reduces this effect. Further, imagination can compensate for the need for touch; yet this finding holds only for the instrumental need for touch, not for the autotelic need for touch. Consequently, we conclude that imagination can compensate for the utilitarian need to touch products in a 360-virtual store.     

Limiting GPR in a two-layer soil model via genetic algorithms

In this paper, an optimum grounding grid that provides the conditions of GPR<E_touch and minimum cost in the structures of two-layer soil model is designed and the length of total conductor and the quantity of ground rod are calculated via Genetic Algorithms (GA). A new approach is presented for the calculation of total conductor length. At the same time, the subject regarding in which layer the ground conductors and rods that form the grounding grid in a substation are to be placed in two-layer soil is analysed using GA. With this as the goal, the depth of optimum grid burial is determined. Our study is compared with the design study for a two-layer soil model in the literature. As a result, the high performance of optimum grid design that is achieved using GA is emphasized by varied applications.
