No ethics settings for autonomous vehicles
Autonomous vehicles (AVs) are expected to improve road traffic safety and save human lives. It is also expected that some AVs will encounter so-called dilemmatic situations, like choosing between saving two passengers by sacrificing one pedestrian or choosing between saving three pedestrians by sacrificing one passenger. These expectations fuel the extensive debate over the ethics settings of AVs: the way AVs should be programmed to act in dilemmatic situations and who should decide about the nature of this programming in the first place. In the article, the ethics settings problem is analyzed as a trilemma between AVs with personal ethics setting (PES), AVs with mandatory ethics setting (MES) and AVs with no ethics settings (NES). It is argued that both PES and MES, by being programmed to choose one human life over the other, are bound to cause serious moral damage resulting from the violation of several principles central to deontology and utilitarianism. NES is defended as the only plausible solution to this trilemma, that is, as the solution that sufficiently minimizes the number of traffic fatalities without causing any comparable moral damage
Aplikacija neophodne traktorske elektroopreme sa ciljem izbora dobavljača
It was noticed that a certain number of suppliers of electronic equipment
put on the market the goods of unknown origin in latest years. Therefore, tractor
manufacturers before proceeding with installation of product they must carry out
necessary tests in terms of quality checks to protect the validity of their products out to
market. Basic remarks were that the suppliers of electrical equipment didn’t have
complete technical documentation for product they offer, in order to fulfill quality of the
tractor as whole product.
Electrical equipment should have a satisfactory quality which is evidenced by the
necessary technical documentation and the certification with the applicable standards for
their purposes. When the tractor manufacturer seeks from the suppliers of electrical
equipment for cooperation, it requires that with received sample and is all relevant
technical documentation. As for the manufacturer it is necessary for the methodology
and procedures are how to test the observed sample. This means that by determining the
basic technical and functional characteristics, manufacturer has to define technical
conditions and requirements for technical criteria by assessing required quality. Thus,
the results are compared with the established technical requirements and the criteria in
technical documentation are based on which appreciation is made and in the validity of
the quality-of-technical system. Following these tests and comparative analysis of the
manufacturer decides to have positive evaluated a sample of electronic equipment that
can be mounted on the respective tractors.
So far, the tractor manufacturer IMR performs testing of certain types for electronic
equipment and tractor according to the prescribed procedures and methodology, and by
that accordingly choose suppliers.Uočeno je da određeni broj dobavljača elektroopreme u zadnjim godinama
plasira na tržište robu nepoznatog porekla. Proizvođači traktora pre ugradnje moraju da izvrše
potrebna ispitivanja, u smislu provere kvaliteta, kako bi zaštitili valjanost svoga proizvoda.
Osnovne primedbe su da snabdevači elektroopreme ne poseduju kompletnu tehničku
dokumentaciju za proizvod koji nude, čime dovode u pitanje kvalitet traktora u celini.
Elektrooprema treba da ima zadovoljavajući kvalitet, što se dokazuje potrebnom
tehničkom dokumentacijom i sertifikacijom po važećim standardima za svoje namene. Kada
proizvođač traktora potražuje elektroopremu od dobavljača, on zahteva da uz pristigle uzorke
bude i relevantna tehnička dokumentacija. Kod proizvođača, metodologije i procedure
podrazumevaju način ispitivanja posmatranog uzorka. Ispitivanja se odnose na određivanje
osnovnih tehničko-funkcionalnih karakteristika, tehničke uslove i zahteve kao i tehničke
kriterijume za ocenu potrebnog kvaliteta. Na taj način dobijeni rezultati upoređuju se sa
postavljenim tehničkim zahtevima i kriterijumima u tehničkoj dokumentaciji, na osnovu čega
se donosi oceana o valjanosti upotrebnog kvaliteta tehničkog sistema. Nakon obavljenih
ispitivanja i uporednih analiza, proizvođač donosi odluku da se pozitivno ocenjeni uzorak
elektroopreme može ugraditi na odnosne traktore.
Dakle i proizvođač traktora IMR vrši ispitivanja određene vrste traktorske elektroopreme
po propisanim procedurama i metodologiji i shodno tome vrši odabir dobavljača

Broj otvora na gorioniku zagrejača ima direktan uticaj na plamen odnosno na pouzdano startovanja dizel motora
Mating Intelligence, Moral Virtues, and Methodological Vices
According to the ‘mating intelligence’ theory by evolutionary psychologist Geoffrey Miller, human morality is a system of sexually selected traits which serve as costly signals to the other sex about one’s fitness and readiness to take care for possible offspring. Starting from the standard prediction of evolutionary psychology that sexual selection produces psychological sex differences in human mating strategies, ‘mating intelligence’ theory is analyzed for its compatibility with several psychological theories about sex differences in moral traits like moral reasoning, judgment and orientation. It is argued that the ‘mating intelligence’ theory, as a theory about the the evolution of morality, comes too dangerously close to being unfalsifiable because it embodies some auxiliary hypotheses and vague definitions which make it practically immune to every possible empirical finding concerning sex differences in human moral traits
