Negative feedbackNegative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances. Whereas positive feedback tends to lead to instability via exponential growth, oscillation or chaotic behavior, negative feedback generally promotes stability. Negative feedback tends to promote a settling to equilibrium, and reduces the effects of perturbations.
Web crawlerA Web crawler, sometimes called a spider or spiderbot and often shortened to crawler, is an Internet bot that systematically browses the World Wide Web and that is typically operated by search engines for the purpose of Web indexing (web spidering). Web search engines and some other websites use Web crawling or spidering software to update their web content or indices of other sites' web content. Web crawlers copy pages for processing by a search engine, which indexes the downloaded pages so that users can search more efficiently.
Impression managementImpression management is a conscious or subconscious process in which people attempt to influence the perceptions of other people about a person, object or event by regulating and controlling information in social interaction. It was first conceptualized by Erving Goffman in 1959 in The Presentation of Self in Everyday Life, and then was expanded upon in 1967. Impression management behaviors include accounts (providing "explanations for a negative event to escape disapproval"), excuses (denying "responsibility for negative outcomes"), and opinion conformity ("speak(ing) or behav(ing) in ways consistent with the target"), along with many others.
Services marketingServices marketing is a specialized branch of marketing which emerged as a separate field of study in the early 1980s, following the recognition that the unique characteristics of services required different strategies compared with the marketing of physical goods. Services marketing typically refers to both business to consumer (B2C) and business-to-business (B2B) services, and includes the marketing of services such as telecommunications services, financial services, all types of hospitality, tourism leisure and entertainment services, car rental services, health care services, professional services and trade services.
