Covariance and contravariance (computer science): Many programming language type systems support subtyping.  For instance, if is subtype of , then an expression of type can be used whenever an expression of type could.  Variance refers to how subtyping between more complex types (list of s versus list of s, function returning versus function returning , ...) relates to subtyping between their components.  Depending on the variance of the type constructor, the subtyping relation may be either preserved, reversed, or ignored.  For example in OCaml, "list of Cat" is a subtype of "list of Animal" because the list constructor is covariant, while "function from Animal to String" is a subtype of "function from Cat to String" because the function type constructor is contravariant in the argument type.

Perro de Presa Canario: The Perro de Presa Canario, A.K.A. the Canary Mastiff, is a large Molosser-type dog breed originally bred for working livestock.  The name of the breed is Spanish, means "Canarian catch dog", and is often shortened to "Presa Canario" or simply "Presa".

Halls Heeler: The Halls Heeler was a dog bred by Thomas Simpson Hall to herd cattle on the Hall family's extensive properties in north-western New South Wales in the 19th century.  On "Dartbrook Station", in the Upper Hunter Valley, Hall selectively crossed the offspring of Northumberland Drover's Dogs (Border Collie lineage) that he had imported, with progeny of dingoes that he had tamed.  By 1840 he had bred the type of dog that he needed to control cattle on the massive runs that his family owned, and until he died in 1870 few of these dogs were owned and used by anyone outside the Hall family and their workers.  However the death of Thomas Hall and the break-up of the Hall estate coincided with the development of the dog show, and an interest in breeding dogs to specific criteria or standards.  The Halls Heeler was further developed into two contemporary dog breeds the Australian Cattle Dog and the Australian Stumpy Tail Cattle Dog.  The name is spelled both with the possessive apostrophe, as Hall's Heeler, and without.

Smuggling of firearms into Mexico: Mexicans have a right to own firearms, but legal purchase from the single Mexican gun shop in Mexico City, controlled by the Army, is extremely difficult.  Guns smuggled into Mexico are sometimes obtained at gunshops in the United States and carried across the US-Mexico border.  In other cases the guns are obtained through Guatemalan borders or stolen from the police or military.  Consequently, black market firearms are widely available.  Many firearms are acquired in the U.S. by women with no criminal history, who transfer their purchases to smugglers through relatives, boyfriends and acquaintances and then smuggled to Mexico a few at a time.  The most common smuggled firearms include AR-15 and AK-47 type rifles, and FN 5.7 caliber semi-automatic pistols.  Many firearms are purchased in the United States in a semi-automatic configuration before being converted to fire as select fire machine guns.  Mexico seized in 2009 a combined total of more than 4,400 firearms of the AK-47 and AR-15 type, and 30% of AK-47 type rifles seized have been modified to select fire weapons, effectively creating assault rifles.
