The Path to Purchase during Shopping
Full text linkIncreasingly shopping behaviour is being seen from the holistic perspective of the entire shopping experience. The experiential view of shopping takes a far more holistic approach to the consumption process, right from involvement to post purchase usage. The decision making process and value perceptions could vary depending on individual shopping orientations, the cultural orientations as well as the economic and competitive environment in which the consumer shops (Woodruffe, Eccles and Elliott, 2002). This study will attempt to understand the impact of the major factors on the purchase behaviour of shoppers by examining purchase paths across different product categories signifying different shopping orientations; across culturally distinct regions; and across different stages of retail evolution.
Synthesis and characterization of biocompatible bimetallic-semi-aromatic polyester hybrid nanocomposite
No full textFunding Information: Dr. Piyush Kumar Gupta is thankful to the Department of Life Sciences, Sharda University, Greater Noida, India for providing infrastructure and research facilities. Publisher Copyright: © 2021 Elsevier B.V.Nanocomposites have been broadly used in bioelectronic, biosensing, photocatalytic, and bioimaging. Moreover, its use in bioengineering field is emerging continuously. The present study reports first-time the synthesis of a novel bimetallic-semi-aromatic polyester hybrid nanocomposite. The obtained MnFe2O4-poly(tBGE-alt-PA) hybrid nanocomposite was physicochemically characterized. FTIR analysis confirmed the synthesis of hybrid nanocomposite. XRD data showed the crystal nature of hybrid nanocomposite due to MnFe2O4 nanoparticles (NPs). TGA study presented the thermostable nature of hybrid nanocomposite and DSC analysis exhibited the absence of chemical interactions between the copolymer and MnFe2O4 NPs in hybrid nanocomposite. Further, the net negative charge was measured on the surface of this almost spherical hybrid nanocomposite. Later, we observed the biocompatible and hemocompatible nature of nanocomposite and in future, it may open many novel avenues in various fields of biomedical science.Peer reviewe

Abstract
Background
Radiotherapy in brain tumors needs accuracy and reproducibility of the patient’s position. There may be set up errors which are taken care by adding planning target volume (PTV) margin. Lesser PTV margins may lead to tumor miss or greater margins may lead to unnecessary radiation of normal brain tissue. The present study is done to evaluate whether the current practice of PTV margins in our institute is optimum or not.
Materials and methods
Eleven patients of brain tumours who received adjuvant radiotherapy were retrospectively selected for determining the setup errors. These patients were immobilised in supine position and contrast enhanced CT of head was taken for radiotherapy planning. Delineation of gross tumor volume and clinical target volume was done with 5 mm PTV margin. The treatment was delivered by 3-Dimensional Conformal Radiotherapy or Intensity Modulated Radiotherapy Technique. The set up errors in three dimensions were determined retrospectively for all images. PTV margins were calculated using International Commission on Radiation Units And Measurements Report 62, Stroom’s and Van Herk formulae.
Results
The overall population set up error was 0.034,-0.048, 0.028 in X, Y, Z directions respectively. The population systematic error was calculated to be 0.107, 0.069, 0.092 and population random error was 0.221, 0.202, 0.217 in X, Y, Z directions respectively. The calculated setup margin as per the three formulas was less than 5 mm in all directions.
Conclusion
The present study showed that the institutional protocol of 5 mm is optimum to counter the setup errors.

Point of Purchase Communication: Role of Information Search, Store Benefit and Shopping Involvement
Full text linkPoint of Purchase (PoP) is the place where a customer is about to buy the product. This is the crucial point where the exchange takes place. It offers us a last chance to remind or attract customers. In spite of a considerable expenditure on point of purchase material by companies, there is a lack of an established method of measuring the effectiveness of communication at the retail outlet. The current study is an attempt to define and measure the extent of usage of PoP by consumers while shopping. It explores the phenomenon with the help of an experimentation using two main variables; level of information search and store benefits sought. It uses shopping involvement as a mediating variable. During the course of study scales for usage of PoP communication and shopping involvement were developed. In-depth interviews were carried among shoppers to understand their motivations and gratifications with regard to shopping. The interview findings were used to develop scales, which were tested before being used during the experiment. The experiments involved building scenarios specific to shopping situations. Participant observations were carried out at stores with different formats. The study found that all the three variables were significant in terms of main as well as interaction effects. Based on the findings the authors suggest a framework for enhancing the effectiveness of PoP Communication.
