Dual-member Proportional Representation
The dual-member mixed proportional (DMP) voting method is a mixed electoral system using a localized list rule to elect two representatives in each district. It is similar to other forms of mixed-member proportional representation, but differs from the additional-member system in that all representatives are elected locally in small districts, rather than requiring separate list seats to be filled in large regional or nationwide districts. In the first step, one seat in each district is awarded to the candidate or party with the most votes, as with first-past-the-post voting rules. In the second step, underrepresented parties are assigned secondary seats in the districts in which they won the most votes, which creates an overall proportional result. DMP was invented in 2013 by a University of Alberta mathematics student named Sean Graham. The system was intended as a possible replacement for single-member plurality (SMP) in Canadian national and provincial elections. After c ...

Electoral System
An electoral or voting system is a set of rules used to determine the results of an election. Electoral systems are used in politics to elect governments, while non-political elections may take place in business, nonprofit organizations and informal organisations. These rules govern all aspects of the voting process: when elections occur, Suffrage, who is allowed to vote, Nomination rules, who can stand as a candidate, Voting method, how ballots are marked and cast, how the ballots are counted, how votes translate into the election outcome, limits on Campaign finance, campaign spending, and other factors that can affect the result. Political electoral systems are defined by constitutions and electoral laws, are typically conducted by election commissions, and can use multiple types of elections for different offices. Some electoral systems elect a single winner to a unique position, such as prime minister, president or governor, while others elect multiple winners, such as membe ...

2009 British Columbia Electoral Reform Referendum
Following the 2005 British Columbia electoral reform referendum, 2005 electoral reform referendum, British Columbia held a second referendum on electoral reform in conjunction with the 2009 British Columbia general election, provincial election on May 12, 2009. As in 2005, voters in 2009 were asked were asked which electoral system should be used to elect legislators: the existing first-past-the-post voting, first-past-the-post electoral system or the BC-STV, BC single transferable vote electoral system (BC-STV) proposed by the Citizens' Assembly on Electoral Reform (British Columbia), British Columbia Citizen's Assembly on Electoral Reform to ensure more proportional representation in the provincial Legislative Assembly. The referendum was defeated, with 60.9 percent voting against the reform and 39.09 percent of voters supporting the change. BC later held another 2018 British Columbia electoral reform referendum, referendum on electoral reform in 2018. Scheduling The governme ...

Wasted Vote
In electoral systems, a wasted vote is any vote cast that is not "used" to elect a winner, and so is not represented in the outcome. However, the term is vague and ill-defined, having been used to refer to a wide variety of unrelated concepts and metrics. The analysis depends on the way a "wasted vote" is defined. Wasted votes seldom affect each party equally irrespective of the system that produces them. More wasted votes for one party and fewer for another create a disproportionate chamber of elected members. Distortions produced by wasted votes work against the aim of fairly reflecting the wishes of the electorate. However, a system that produces wasted votes may prevent instability caused by many parties being elected to the legislature. Terminology There are at least two different types of wasted votes: Wasted votes and efficiency gap are defined pp. 850–852. * Lost votes are votes that make no impact on which candidates are elected. These votes do not actually elect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continuous Function
In mathematics, a continuous function is a function such that a small variation of the argument induces a small variation of the value of the function. This implies there are no abrupt changes in value, known as '' discontinuities''. More precisely, a function is continuous if arbitrarily small changes in its value can be assured by restricting to sufficiently small changes of its argument. A discontinuous function is a function that is . Until the 19th century, mathematicians largely relied on intuitive notions of continuity and considered only continuous functions. The epsilon–delta definition of a limit was introduced to formalize the definition of continuity. Continuity is one of the core concepts of calculus and mathematical analysis, where arguments and values of functions are real and complex numbers. The concept has been generalized to functions between metric spaces and between topological spaces. The latter are the most general continuous functions, and their d ...

Electoral Threshold
The electoral threshold, or election threshold, is the minimum share of votes that a candidate or political party requires before they become entitled to representation or additional seats in a legislature. This limit can operate in various ways; for example, in party-list proportional representation systems where an electoral threshold requires that a party must receive a specified minimum percentage of votes (e.g. 5%), either nationally or in a particular electoral district, to obtain seats in the legislature. In single transferable voting, the election threshold is called the quota, and it is possible to achieve it by receiving first-choice votes alone or by a combination of first-choice votes and votes transferred from other candidates based on lower preferences. In mixed-member-proportional (MMP) systems, the election threshold determines which parties are eligible for top-up seats in the legislative chamber. Some MMP systems still allow a party to retain the seats the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
District Threshold
A district is a type of administrative division that in some countries is managed by the local government. Across the world, areas known as "districts" vary greatly in size, spanning regions or counties, several municipalities, subdivisions of municipalities, school district, or political district. Etymology The word "district" in English is a loan word from French. It comes from Medieval Latin districtus–"exercising of justice, restraining of offenders". The earliest known English-language usage dates to 1611, in the work of lexicographer Randle Cotgrave. By country or territory Afghanistan In Afghanistan, a district (Persian ) is a subdivision of a province. There are almost 400 districts in the country. Australia Electoral districts are used in state elections. Districts were also used in several states as cadastral units for land titles. Some were used as squatting districts. New South Wales had several different types of districts used in the 21st century ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plurality Voting
Plurality voting refers to electoral systems in which the candidates in an electoral district who poll more than any other (that is, receive a plurality) are elected. Under single-winner plurality voting, and in systems based on single-member districts, plurality voting is called single member istrictplurality (SMP), which is widely known as " first-past-the-post". In SMP/FPTP the leading candidate, whether or not they have a majority of votes, is elected. There are several versions of plurality voting for multi-member district. The system that elects multiple winners at once with the plurality rule and where each voter casts as many X votes as the number of seats in a multi-seat district is referred to as plurality block voting. A semi-proportional system that elects multiple winners elected at once with the plurality rule and where each voter casts more than one vote but fewer than the number of seats to fill in a multi-seat district is known as limited voting. A semi-prop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New States Paradox
Coherence, also called uniformity or consistency, is a criterion for evaluating rules for fair division. Coherence requires that the outcome of a fairness rule is fair not only for the overall problem, but also for each sub-problem. Every part of a fair division should be fair. The coherence requirement was first studied in the context of apportionment. In this context, failure to satisfy coherence is called the new states paradox: when a new U.S. state enters the union, and the number of seats in the House of Representatives is enlarged to accommodate the number of seats allocated to this new state, some other unrelated states are affected. Coherence is also relevant to other fair division problems, such as bankruptcy problems. Definition There is a ''resource'' to allocate, denoted by h. For example, it can be an integer representing the number of seats in a ''h''ouse of representatives. The resource should be allocated between some n ''agents''. For example, these can be fe ...

Largest Remainders Method
Party-list proportional representation Apportionment methods The quota or divide-and-rank methods make up a category of apportionment rules, i.e. algorithms for allocating seats in a legislative body among multiple groups (e.g. parties or federal states). The quota methods begin by calculating an entitlement (basic number of seats) for each party, by dividing their vote totals by an electoral quota (a fixed number of votes needed to win a seat, as a unit). Then, leftover seats, if any are allocated by rounding up the apportionment for some parties. These rules are typically contrasted with the more popular highest averages methods (also called divisor methods). By far the most common quota method are the largest remainders or quota-shift methods, which assign any leftover seats to the "plurality" winners (the parties with the largest remainders, i.e. most leftover votes). When using the Hare quota, this rule is called Hamilton's method, and is the third-most common app ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apportionment (politics)
Apportionment is the process by which seats in a Legislature, legislative body are distributed among administrative divisions, such as states or parties, entitled to Representation (politics), representation. This page presents the general principles and issues related to apportionment. The apportionment by country page describes the specific practices used around the world. The Mathematics of apportionment page describes mathematical formulations and properties of apportionment rules. The simplest and most universal principle is that elections should One man, one vote, give each vote an equal weight. This is both intuitive and stated in laws such as the Fourteenth Amendment to the United States Constitution (the Equal Protection Clause). One example of deliberate malapportionment is seen in bicameral legislatures: while one house, often called a house of commons or representatives, is based on proportional representation, the other is based on regional representation.

Mixed Single Vote
A mixed single vote (MSV) is a type of ballot in mixed-member electoral systems, where voters cast a single vote in an election, which is used both for electing a local candidate and as a vote for a party affiliated with that candidate according to the rules of the electoral system. Unlike most mixed proportional and mixed majoritarian systems (such as parallel voting) where voters cast two votes, split-ticket voting is not possible under MSV. This significantly reduces the possibility of manipulating compensatory mixed systems,Bochsler, Daniel. "Bending the rules: electoral strategies under mixed electoral systems." ''Representation'' 51.2 (2015): 261-267. at the price of reducing voter choice. An alternative based on the mixed single vote that still allows for indicating different preferences on different levels is the mixed ballot, which functions as a preferential (mixed) single vote. With MSV, voters usually cast their single vote for a local candidate in a single-m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
