Simple random sampleIn statistics, a simple random sample (or SRS) is a subset of individuals (a sample) chosen from a larger set (a population) in which a subset of individuals are chosen randomly, all with the same probability. It is a process of selecting a sample in a random way. In SRS, each subset of k individuals has the same probability of being chosen for the sample as any other subset of k individuals. A simple random sample is an unbiased sampling technique. Simple random sampling is a basic type of sampling and can be a component of other more complex sampling methods.
ElectionAn election is a formal group decision-making process by which a population chooses an individual or multiple individuals to hold public office. Elections have been the usual mechanism by which modern representative democracy has operated since the 17th century. Elections may fill offices in the legislature, sometimes in the executive and judiciary, and for regional and local government. This process is also used in many other private and business organisations, from clubs to voluntary associations and corporations.
Negative selection (natural selection)In natural selection, negative selection or purifying selection is the selective removal of alleles that are deleterious. This can result in stabilising selection through the purging of deleterious genetic polymorphisms that arise through random mutations. Purging of deleterious alleles can be achieved on the population genetics level, with as little as a single point mutation being the unit of selection. In such a case, carriers of the harmful point mutation have fewer offspring each generation, reducing the frequency of the mutation in the gene pool.
Directional selectionIn population genetics, directional selection, is a mode of negative natural selection in which an extreme phenotype is favored over other phenotypes, causing the allele frequency to shift over time in the direction of that phenotype. Under directional selection, the advantageous allele increases as a consequence of differences in survival and reproduction among different phenotypes. The increases are independent of the dominance of the allele, and even if the allele is recessive, it will eventually become fixed.
Citizens' assemblyA citizens' assembly is a group of people selected by lottery from the general population to deliberate on important public questions so as to exert an influence. Other names and variations include citizens' jury, citizens' panel, people's panel, mini-publics, people's jury, policy jury, citizens' initiative review, consensus conference and citizens' convention. A citizens' assembly uses elements of a jury to create public policy.
MagistrateThe term magistrate is used in a variety of systems of governments and laws to refer to a civilian officer who administers the law. In ancient Rome, a magistratus was one of the highest ranking government officers, and possessed both judicial and executive powers. In other parts of the world, such as China, a magistrate was responsible for administration over a particular geographic area. Today, in some jurisdictions, a magistrate is a judicial officer who hears cases in a lower court, and typically deals with more minor or preliminary matters.
PoliticsPolitics () is the set of activities that are associated with making decisions in groups, or other forms of power relations among individuals, such as the distribution of resources or status. The branch of social science that studies politics and government is referred to as political science. It may be used positively in the context of a "political solution" which is compromising and nonviolent, or descriptively as "the art or science of government", but also often carries a negative connotation.
VenetoVeneto (USˈvɛnətoʊ,_ˈveɪn-, ˈvɛːneto; Vèneto ˈvɛneto; Unieja; Venezien) or Venetia is one of the 20 regions of Italy. Its population is about five million, ranking fourth in Italy. The region's capital is Venice while the largest city is Verona. Veneto was part of the Roman Empire until the 5th century AD. Later, after a feudal period, it was part of the Republic of Venice until 1797. Venice ruled for centuries over one of the largest and richest maritime republics and trade empires in the world.
Doge of VeniceThe Doge of Venice (doʊdʒ ) sometimes translated as Duke (compare the Italian Duca), was the chief magistrate and leader of the Republic of Venice between 726 and 1797. Doges of Venice were elected for life by the Venetian nobility. The doge was neither a duke in the modern sense, nor the equivalent of a hereditary duke. The title "doge" was the title of the senior-most elected official of Venice and Genoa; both cities were republics and elected doges.
