Problem: In 1644, Rene Descartes theorized that pain was a disturbance that passed down along nerve fibers until the disturbance reached the brain, a development that transformed the perception of pain from a spiritual, mystical experience to a physical, mechanical sensation[citation needed]. Descartes's work, along with Avicenna's, prefigured the 19th-century development of specificity theory. Specificity theory saw pain as "a specific sensation, with its own sensory apparatus independent of touch and other senses". Another theory that came to prominence in the 18th and 19th centuries was intensive theory, which conceived of pain not as a unique sensory modality, but an emotional state produced by stronger than normal stimuli such as intense light, pressure or temperature. By the mid-1890s, specificity was backed mostly by physiologists and physicians, and the intensive theory was mostly backed by psychologists. However, after a series of clinical observations by Henry Head and experiments by Max von Frey, the psychologists migrated to specificity almost en masse, and by century's end, most textbooks on physiology and psychology were presenting pain specificity as fact.

Problem: A long list of AM and FM radio stations broadcast to greater Melbourne. These include "public" (i.e., state-owned ABC and SBS) and community stations. Many commercial stations are networked-owned: DMG has Nova 100 and Smooth; ARN controls Gold 104.3 and KIIS 101.1; and Southern Cross Austereo runs both Fox and Triple M. Stations from towns in regional Victoria may also be heard (e.g. 93.9 Bay FM, Geelong). Youth alternatives include ABC Triple J and youth run SYN. Triple J, and similarly PBS and Triple R, strive to play under represented music. JOY 94.9 caters for gay, lesbian, bisexual and transgender audiences. For fans of classical music there are 3MBS and ABC Classic FM. Light FM is a contemporary Christian station. AM stations include ABC: 774, Radio National, and News Radio; also Fairfax affiliates 3AW (talk) and Magic (easy listening). For sport fans and enthusiasts there is SEN 1116. Melbourne has many community run stations that serve alternative interests, such as 3CR and 3KND (Indigenous). Many suburbs have low powered community run stations serving local audiences.

Problem: The first criminal provision in U.S. copyright law was added in 1897, which established a misdemeanor penalty for "unlawful performances and representations of copyrighted dramatic and musical compositions" if the violation had been "willful and for profit." Criminal copyright infringement requires that the infringer acted "for the purpose of commercial advantage or private financial gain." 17 U.S.C. 506. To establish criminal liability, the prosecutor must first show the basic elements of copyright infringement: ownership of a valid copyright, and the violation of one or more of the copyright holder's exclusive rights. The government must then establish that defendant willfully infringed or, in other words, possessed the necessary mens rea. Misdemeanor infringement has a very low threshold in terms of number of copies and the value of the infringed works.
What isn't the threshold of the number of copies and the value of the works?
