🔗 Extinction 🔗 Evolutionary biology 🔗 Ecology

Conservation-induced extinction is where efforts to save endangered species lead to the extinction of other species. This mostly threatens the parasite and pathogen species that are highly host-specific to critically endangered hosts. When the last individuals of a host species are captured for the purpose of captive breeding and reintroduction programs, they typically undergo anti-parasitic treatments to increase survival and reproductive success. This practice may unintentionally result in the extinction of the species antagonistic to the target species, such as certain parasites. It has been proposed that the parasites should be reintroduced to the endangered population. A few cases of conservation-induced extinction have occurred in parasitic lice.

The No Asshole Rule: Building a Civilized Workplace and Surviving One That Isn't is a book by Stanford professor Robert I. Sutton. He initially wrote an essay for the Harvard Business Review, published in the breakthrough ideas for 2004. Following the essay, he received more than one thousand emails and testimonies. Among other reasons disclosed in another article published at the Harvard Business Review, these letters led him to write the book, sell more than 115,000 copies, and win the Quill Award for best business book in 2007.

The theme of this book is that workplace bullying worsens morale and productivity. To screen out the toxic staff, it suggests the "no asshole rule". The author insists upon use of the word asshole since other words such as bully or jerk "do not convey the same degree of awfulness". In terms of using the word in the book's title, he said "There's an emotional reaction to a dirty title. You have a choice between being offensive and being ignored."

The Kardashev scale is a method of measuring a civilization's level of technological advancement based on the amount of energy they are able to use. The measure was proposed by Soviet astronomer Nikolai Kardashev in 1964. The scale has three designated categories:

• A Type I civilization, also called a planetary civilization—can use and store all of the energy available on its planet.
• A Type II civilization, also called a stellar civilization—can use and control energy at the scale of its stellar system.
• A Type III civilization, also called a galactic civilization—can control energy at the scale of its entire host galaxy.

Synsepalum dulcificum is a plant in the Sapotaceae family, native to tropical Africa. It is known for its berry that, when eaten, causes sour foods (such as lemons and limes) subsequently consumed to taste sweet. This effect is due to miraculin. Common names for this species and its berry include miracle fruit, miracle berry, miraculous berry, sweet berry, and in West Africa, where the species originates, agbayun (in Yoruba), taami, asaa, and ledidi.

The berry itself has a low sugar content and a mildly sweet tang. It contains a glycoprotein molecule, with some trailing carbohydrate chains, called miraculin. When the fleshy part of the fruit is eaten, this molecule binds to the tongue's taste buds, causing sour foods to taste sweet. At neutral pH, miraculin binds and blocks the receptors, but at low pH (resulting from ingestion of sour foods) miraculin binds proteins and becomes able to activate the sweet receptors, resulting in the perception of sweet taste. This effect lasts until the protein is washed away by saliva (up to about 30 minutes).

The names miracle fruit and miracle berry are shared by Gymnema sylvestre and Thaumatococcus daniellii, which are two other species used to alter the perceived sweetness of foods.

E-Prime (short for English-Prime or English Prime, sometimes denoted É or E′) is a version of the English language that excludes all forms of the verb to be, including all conjugations, contractions and archaic forms.

Some scholars advocate using E-Prime as a device to clarify thinking and strengthen writing. A number of other scholars have criticized E-Prime's utility.

The Society for Preventing Parents from Naming Their Children Jennifer (SPPNTCJ) was a popular and sometimes controversial website that contributed to early web culture, online from 1996 to 2000. The SPPNTCJ home page was created and updated by Jennifer Farwell, one of the three founding members of the SPPNTCJ. Other founding members were Jennifer Rich and Jennifer Ang.

The SPPNTCJ began as an inside joke on an email discussion list that both Farwell and Rich subscribed to, which included five or more Jennifers who actively posted at that time. One of the Jennifers tossed out the comment that there should be "a society for preventing parents from naming their children Jennifer." The idea took off, and Farwell created the SPPNTCJ's website. It welcomed more than 2 million visitors while online.

During its run, the SPPNTCJ was noted by the Richmond Times-Dispatch, Yahoo! Internet Life magazine, Thunder Bay Television News, 580 CKPR radio program Tech Talk, California State University, Chico, SignsOnSanDiego.com, WebMD and more. It received several Internet "cool site" acknowledgments, from Cool Central, Seven Wonders, Twoeys, Fallen Thinkers, and Secret Einstein.

Don't Mess with Texas is a slogan for a campaign aimed at reducing littering on Texas roadways by the Texas Department of Transportation. The phrase "Don't Mess with Texas" is prominently shown on road signs on major highways, television, radio and in print advertisements. The campaign is credited with reducing litter on Texas highways roughly 72% between 1987 and 1990. The campaign's target market was 18- to 35-year-old males, which was statistically shown to be the most likely to litter. While the slogan was not originally intended to become a statewide cultural phenomenon, it did.

Beyond its immediate role in reducing litter, the slogan has been popularly appropriated by Texans. The phrase has become "an identity statement, a declaration of Texas swagger". Though the origin of the slogan is not well known outside of Texas, it appears on countless items of tourist souvenirs. Since the phrase is a federally registered trademark, the department has tried at times to enforce its trademark rights with cease and desist letters, but has had very limited success. The slogan is the title of the book, Don’t Mess With Texas: The Story Behind the Legend.

"Don't Mess with Texas" has been awarded a plaque on the Madison Avenue Walk of Fame and a place in the Advertising Hall of Fame, a distinction given to only two slogans annually.

"Don't Mess with Texas" is also the official motto of the Virginia-class submarine USS Texas.

In 2011 the result of a public vote for the best "Don't Mess with Texas" ad over the last 25 was revealed, the winner was one created by the Commemorative Air Force (then called the Confederate Air Force). The ad involved the CAF's Boeing B-17 "Sentimental Journey" pursuing and retaliating against a truck from which trash was thrown.
