Music subscription cases: do consumer change their behavior upon a subscription price change

Started May 3, 2024

Abstract or project description

There are many popular music brands in the United States, such as Spotify. Music brands often set up paid subscriptions to make the software easier to use and the music selection richer for consumers. Subscription prices may vary from software to software. The price of each software subscription is subject to change. Music brands often notify consumers in advance of changes in subscription fees through email or message. This blog will examine whether consumers' subscription choices change after they learn of the change in fees. User behavior may change as costs rise, such as moving to another music brand or dropping their subscription.

Melatonin and its effects

Started May 26, 2023

Abstract or project description

Melatonin is a commonly used substance in humans. It is important to understand their effects and safety, so that they can be effectively prescribed to patients with medical issues, such as sleep problems. This project will overview melatonin with respect to the role and process of melatonin in improving sleep and also identify possible adverse effects (AE) of melatonin. PubMed and google scholar were used for literature search to look at 13 articles.   The literature search includes human melatonin sleep experiments and the short-term adverse effects of melatonin. The analysis of melatonin use included the effects on different populations, adults and elderly. This review examines the effectiveness of melatonin and its possible risks for people with sleep quality needs.
