Question: They invented and developed arithmetic by using several different number systems including a mixed radix system with an alternating base 10 and base 6. This sexagesimal system became the standard number system in Sumer and Babylonia. They may have invented military formations and introduced the basic divisions between infantry, cavalry, and archers. They developed the first known codified legal and administrative systems, complete with courts, jails, and government records. The first true city-states arose in Sumer, roughly contemporaneously with similar entities in what are now Syria and Lebanon. Several centuries after the invention of cuneiform, the use of writing expanded beyond debt/payment certificates and inventory lists to be applied for the first time, about 2600 BC, to messages and mail delivery, history, legend, mathematics, astronomical records, and other pursuits. Conjointly with the spread of writing, the first formal schools were established, usually under the auspices of a city-state's primary temple.

Question: Corruption is not specific to poor, developing, or transition countries. In western countries, cases of bribery and other forms of corruption in all possible fields exist: under-the-table payments made to reputed surgeons by patients attempting to be on top of the list of forthcoming surgeries, bribes paid by suppliers to the automotive industry in order to sell low-quality connectors used for instance in safety equipment such as airbags, bribes paid by suppliers to manufacturers of defibrillators (to sell low-quality capacitors), contributions paid by wealthy parents to the "social and culture fund" of a prestigious university in exchange for it to accept their children, bribes paid to obtain diplomas, financial and other advantages granted to unionists by members of the executive board of a car manufacturer in exchange for employer-friendly positions and votes, etc. Examples are endless. These various manifestations of corruption can ultimately present a danger for the public health; they can discredit specific, essential institutions or social relationships.
Is there an answer to this question: Along with institutions, this type of corruption can discredit what?
