Brand extensions refer to use an established brand name in new product or product categories and are extensively applied as a marketing strategy. Brand extension success factors vary according to cultures. Consumers' attitude towards extensions is modified on the basis of their cognitional reactions and relations between the parent brand and extended product and/ or product categories. This study aims at conducting an exploratory research and revealing the relationship between the parent brand and the extended brand. More specifically, the impact of parent brand loyalty on the extension is explored. Therefore, the main objective is to evaluate the attitudes of consumers towards brand extension strategy in apparel section in Bilaspur. The study analyzes consumers' attitudes towards brand extensions specifically in apparel section. This is in particular to portray that consumers respond positively to brand extensions in various industries due to different motivations. During the methodology application process, in-depth interviews were carried out with 100 participants who were selected randomly from Shopping Store and other places. The interviews were conducted using questionnaire.

Discover how project Reactor enhances the reactive programming paradigm and allows you to build scalable asynchronous applicationsKey FeaturesUse reactive APIs, Flux, and Mono to implement reactive extensionsCreate concurrent applications without the complexity of Java's concurrent APIUnderstand techniques to implement event-driven and reactive applicationsBook DescriptionReactor is an implementation of the Java 9 Reactive Streams specification, an API for asynchronous data processing. This specification is based on a reactive programming paradigm, enabling developers to build enterprise-grade, robust applications with reduced complexity and in less time. Hands-On Reactive Programming with Reactor shows you how Reactor works, as well as how to use it to develop reactive applications in Java.The book begins with the fundamentals of Reactor and the role it plays in building effective applications. You will learn how to build fully non-blocking applications and will later be guided by the Publisher and Subscriber APIs. You will gain an understanding how to use two reactive composable APIs, Flux and Mono, which are used extensively to implement Reactive Extensions. All of these components are combined using various operations to build a complete solution. In addition to this, you will get to grips with the Flow API and understand backpressure in order to control overruns. You will also study the use of Spring WebFlux, an extension of the Reactor framework for building microservices.By the end of the book, you will have gained enough confidence to build reactive and scalable microservices.What you will learnExplore benefits of the Reactive paradigm and the Reactive Streams APIDiscover the impact of Flux and Mono implications in ReactorExpand and repeat data in stream processingGet to grips with various types of processors and choose the best oneUnderstand how to map errors to make corrections easierCreate robust tests using testing utilities offered by ReactorFind the best way to schedule the execution of codeWho this book is forIf you’re looking to develop event- and data-driven applications easily with Reactor, this book is for you.
