Carpi’s Voice Rectifier

January 22nd, 2021

A beautiful or not-so-beautiful voice can be made more beautiful by sticking Carpi’s voice rectifier in one’s mouth, perhaps. The well-more-than-century-old device is enshrined in a patent:

Voice Rectifier,” US patent 527235, granted to Vittorio Carpi, 1894. Carpi explains:

Be it known that I, VITTORIO CARPI, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Voice-Rectifiers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying draw ings, and to the letters of reference marked thereon, which form a part of this specification. This invention relates to devices to be used by singers and others in vocal exercising for the purpose of correcting and perfecting stiff and defective voices and assisting such persons in the proper cultivation and development of the voice….

When the high notes sound too disagreeably thin or woody the practice should be conducted alternately with and without the plate A in the mouth until the person obtains control of the voice, cures the defects above pointed out and acquires a regular, even, extensive and round voice. To this end the voice rectifier will be found extremely convenient in curing throaty and nasal voices and uneven voices in the different registers.

Mis-placement of the device could make the voice less beautiful, perhaps.

Daily Defecation Outputs of Mountain Gorillas

January 19th, 2021

Output takes center stage in this new study of what some gorillas left behind:

Daily Defecation Outputs of Mountain Gorillas (Gorilla beringei beringei) in the Volcanoes National Park, Rwanda,” Elie Sinayitutse, David Modry, Jan Slapeta, Aisha Nyiramana, Antoine Mudakikwa, Richard Muvunyi, and Winnie Eckardt, Primates, epub 2020. (Thanks to Damien Caillaud for bringing this to our attention.)

The authors, at the Dian Fossey Gorilla Fund International; the University of Rwanda, Butare; the University of Veterinary and Pharmaceutical Sciences, Czech Republic; the Czech Academy of Sciences; the University of Sydney, Australia; the University of Rwanda; and the Rwanda Development Board, report:.

“We weighed 399 wet fecal samples deposited at nest sites and on trails between nest sites by gorillas of varying age and sex, determined by lobe diameter, from five social groups (n = 58 gorillas) that range in the Volcanoes National Park, Rwanda. We found increasing daily average defecation outputs with increasing age-sex class (infants, 435 g; juveniles, 1346 g; medium-sized gorillas, 2446 g; silverbacks, 3609 g). Gorillas deposited two– to threefold the amount of feces at nest sites compared to on trails, suggesting that nest sites may function as hotspots for enteric pathogen infections through direct contact or when gorillas ingest foods contaminated with infectious larvae during site revisits in intervals matching the maturation period of environmentally transmitted gastrointestinal parasites.”

PERSONAL (by Marc) NOTE: In my 9th grade biology class the teacher gave me an F on a book report, because she insisted I was concocting the details. The details were about observing gorilla droppings. The book, I’m pretty sure, was either by or about Dian Fossey. The teacher was so angry at me that, even after I retrieved the book from the library and showed her the things I had described she still insisted on giving me an F for that report. It’s the only F I ever got, and I am still proud of it.

Coffee shop restroom graffiti and their implications for management inquiries [study]

January 18th, 2021

“My intention is to explore what happens when an organization’s bathroom becomes the locus of heated debate and cynical resignation. In contrast to viewing this rarely studied space as irrelevant to culture and identity, I argue that addressing such a space as culturally important has strong implications for understanding how authorship is constituted in organizations.“

So explains Professor Gazi Islam (now at the Grenoble Ecole de Management, France) in an article entitled : Backstage Discourse and the Emergence of Organizational Voices: Exploring Graffiti and Organization. (Journal of Management Inquiry, Volume: 19 issue: 3, page(s): 246-260)

The professor examined the dense and polyphonic communicative acts – in the form of graffiti – that had been found in the bathroom (restroom) of a locally-owned coffee shop in a medium-sized US city.

Graffiti were recorded approximately bi-weekly over 3 years, resulting in 338 separate entries of graffiti texts. Which were subsequently incorporated into a working categorization scheme based on their discursive functions.

“The phenomena I attempt to examine exist in dark corners of the organization but contain novel and interesting information, novel because seldom studied, and interesting, because they have managed to flourish, even in secrecy. These phenomena are organizational in the sense that civil society is political, that is, as spaces where meanings are established that do not enter the formal organizational registers. It is my hope that such a choice of research site, with its unique attributes, will open a door for future research into the more private spheres of organizations.”
