Striking clockA striking clock is a clock that sounds the hours audibly on a bell, gong, or other audible device. In 12-hour striking, used most commonly in striking clocks today, the clock strikes once at 1:00 am, twice at 2:00 am, continuing in this way up to twelve times at 12:00 mid-day, then starts again, striking once at 1:00pm, twice at 2:00 pm, up to twelve times at 12:00 midnight. The striking feature of clocks was originally more important than their clock faces; the earliest clocks struck the hours, but had no dials to enable the time to be read.
Specific performanceSpecific performance is an equitable remedy in the law of contract, whereby a court issues an order requiring a party to perform a specific act, such as to complete performance of the contract. It is typically available in the sale of land law, but otherwise is not generally available if damages are an appropriate alternative. Specific performance is almost never available for contracts of personal service, although performance may also be ensured through the threat of proceedings for contempt of court.
High-context and low-context culturesIn anthropology, high-context culture and low-context culture are ends of a continuum of how explicit the messages exchanged in a culture are and how important the context is in communication. The continuum pictures how people communicate with others through their range of communication abilities: utilizing gestures, relations, body language, verbal messages, or non-verbal messages. "High-" and "low-" context cultures typically refer to language groups, nationalities, or regional communities.
