Experimental Political Science
Experimental political science is the use of experiments, which may be natural or controlled, to implement the scientific method in political science. History development and usage In the 1909 American Political Science Association presidential address, A. Lawrence Lowell claimed: “We are limited by the impossibility of experiment. Politics is an observational, not an experimental science….” He argued that political science, as an emerging discipline, did not need to follow the experimental-led approach of the natural sciences. In the 1900s, observational research was the only way of doing research in political science. The first experiment in political science is regarded to be Harold Gosnell's 1924 study on voter turnout in Chicago. In this experiment, he randomly assigned districts to receive information on voter registration and encouragement to vote. In the 1950s, the behaviorist revolution was in full swing, and the development of experimental politics ushered in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Experiment
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into Causality, cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results. There also exist natural experiment, natural experimental studies. A child may carry out basic experiments to understand how things fall to the ground, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time. Experiments can vary from personal and in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voting Systems
An electoral system or voting system is a set of rules that determine how elections and referendums are conducted and how their results are determined. Electoral systems are used in politics to elect governments, while non-political elections may take place in business, non-profit organisations and informal organisations. These rules govern all aspects of the voting process: when elections occur, who is allowed to vote, who can stand as a candidate, how ballots are marked and cast, how the ballots are counted, how votes translate into the election outcome, limits on 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 memb ...

Social Choice Theory
Social choice theory or social choice is a theoretical framework for analysis of combining individual opinions, preferences, interests, or welfares to reach a ''collective decision'' or ''social welfare'' in some sense.Amartya Sen (2008). "Social Choice,". ''The New Palgrave Dictionary of Economics'', 2nd EditionAbstract & TOC./ref> Whereas choice theory is concerned with individuals making choices based on their preferences, social choice theory is concerned with how to translate the preferences of individuals into the preferences of a group. A non-theoretical example of a collective decision is enacting a law or set of laws under a constitution. Another example is voting, where individual preferences over candidates are collected to elect a person that best represents the group's preferences. Social choice blends elements of welfare economics and public choice theory. It is methodologically individualistic, in that it aggregates preferences and behaviors of individual member ...

Public Choice Theory
Public choice, or public choice theory, is "the use of economic tools to deal with traditional problems of political science".Gordon Tullock, 9872008, "public choice," ''The New Palgrave Dictionary of Economics''. . Its content includes the study of political behavior. In political science, it is the subset of positive political theory that studies self-interested agents (voters, politicians, bureaucrats) and their interactions, which can be represented in a number of ways – using (for example) standard constrained utility maximization, game theory, or decision theory. It is the origin and intellectual foundation of contemporary work in political economy.Alberto Alesina, Torsten Persson, Guido Tabellini, 2006. “Reply to Blankart and Koester's Political Economics versus Public Choice Two Views of Political Economy in Competition,” Kyklos, 59(2), pp. 201–208 In popular use, "public choice" is often used as a shorthand for components of modern public choice theory that fo ...

Psephology
Psephology (; from Greek el, ψῆφος, psephos, pebble, label=none) or political analysis is a branch of political science, the "quantitative analysis of elections and balloting". As such, psephology attempts to explain elections using the scientific method. Psephology is related to political forecasting. Psephology uses historical precinct voting data, public opinion polls, campaign finance information and similar statistical data. The term was coined in 1948 in the United Kingdom by W. F. R. Hardie (1902–1990) after he was asked by his friend R. B. McCallum for a word to describe the study of elections; first written use in 1952.

Experimental Psychology
Experimental psychology refers to work done by those who apply experimental methods to psychological study and the underlying processes. Experimental psychologists employ human participants and animal subjects to study a great many topics, including (among others) sensation & perception, memory, cognition, learning, motivation, emotion; developmental processes, social psychology, and the neural substrates of all of these. History Early experimental psychology Wilhelm Wundt Experimental psychology emerged as a modern academic discipline in the 19th century when Wilhelm Wundt introduced a mathematical and experimental approach to the field. Wundt founded the first psychology laboratory in Leipzig, Germany. Other experimental psychologists, including Hermann Ebbinghaus and Edward Titchener, included introspection in their experimental methods. Charles Bell Charles Bell was a British physiologist whose main contribution to the medical and scientific c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Experimental Economics
Experimental economics is the application of experimental methods to study economic questions. Data collected in experiments are used to estimate effect size, test the validity of economic theories, and illuminate market mechanisms. Economic experiments usually use cash to motivate subjects, in order to mimic real-world incentives. Experiments are used to help understand how and why markets and other exchange systems function as they do. Experimental economics have also expanded to understand institutions and the law (experimental law and economics). A fundamental aspect of the subject is design of experiments. Experiments may be conducted in the field or in laboratory settings, whether of individual or group behavior. Variants of the subject outside such formal confines include natural and quasi-natural experiments. Experimental topics One can loosely classify economic experiments using the following topics: * Markets * Games * Evolutionary game theory * Decision making * Barg ...

External Validity
External validity is the validity of applying the conclusions of a scientific study outside the context of that study. In other words, it is the extent to which the results of a study can be generalized to and across other situations, people, stimuli, and times.Aronson, E., Wilson, T. D., Akert, R. M., & Fehr, B. (2007). Social psychology. (4 ed.). Toronto, ON: Pearson Education. In contrast, internal validity is the validity of conclusions drawn ''within'' the context of a particular study. Because general conclusions are almost always a goal in research, external validity is an important property of any study. Mathematical analysis of external validity concerns a determination of whether generalization across heterogeneous populations is feasible, and devising statistical and computational methods that produce valid generalizations. Threats "A threat to external validity is an explanation of how you might be wrong in making a generalization from the findings of a particular study ...

Internal Validity
Internal validity is the extent to which a piece of evidence supports a claim about cause and effect, within the context of a particular study. It is one of the most important properties of scientific studies and is an important concept in reasoning about evidence more generally. Internal validity is determined by how well a study can rule out alternative explanations for its findings (usually, sources of systematic error or 'bias'). It contrasts with external validity, the extent to which results can justify conclusions about other contexts (that is, the extent to which results can be generalized). Details Inferences are said to possess internal validity if a causal relationship between two variables is properly demonstrated.Shadish, W., Cook, T., and Campbell, D. (2002). Experimental and Quasi-Experimental Designs for Generilized Causal Inference Boston:Houghton Mifflin. A valid causal inference may be made when three criteria are satisfied: # the "cause" precedes the "eff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agenda (meeting)
An agenda is a list of meeting activities in the order in which they are to be taken up, beginning with the call to order and ending with adjournment. It usually includes one or more specific items of business to be acted upon. It may, but is not required to, include specific times for one or more activities. An agenda may also be called a docket, schedule, or calendar. It may also contain a listing of an order of business. Etymology ''Agenda'' is an abbreviation of ''agenda sunt'' or ''agendum est'', gerundive forms in plural and singular respectively of the Latin verb ''ago, agere, egi, actum'' "to drive on, set in motion", for example of cattle. The meaning is "(those things/that thing) which must be driven forward". What is now known in English as an ''agenda'' is a list of individual items which must be "acted upon" or processed, usually those matters which must be discussed at a business meeting. Although the Latin word is in a plural form, as a borrowed word in English, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voting Methods In Deliberative Assemblies
Deliberative assemblies – bodies that use parliamentary procedure to arrive at decisions – use several methods of voting on motions (formal proposal by members of a deliberative assembly that the assembly take certain action). The regular methods of voting in such bodies are a voice vote, a rising vote, and a show of hands. Additional forms of voting include a recorded vote and balloting. Regular methods Voice vote ''Robert's Rules of Order Newly Revised'' (RONR) states that a voice vote (''viva voce'') is the usual method of voting on any motion that does not require more than a majority vote for its adoption. It is considered the simplest and quickest of voting methods used by deliberative assemblies. The chair of the assembly will put the question to the assembly, asking first for those in favor of the motion to indicate so verbally ("aye" or "yes"), and then ask those opposed to the motion to indicate so verbally ("no"). The chair will then estimate which side had more m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deliberative Assembly
A deliberative assembly is a meeting of members who use parliamentary procedure. Etymology In a speech to the electorate at Bristol in 1774, Edmund Burke described the British Parliament as a "deliberative assembly," and the expression became the basic term for a body of persons meeting to discuss and determine common action. Characteristics ''Robert's Rules of Order Newly Revised'' by Henry Martyn Robert describes the following characteristics of a deliberative assembly: * A group of people meets to discuss and make decisions on behalf of the entire membership. * They meet in a single room or area, or under equivalent conditions of simultaneous oral communication. * Each member is free to act according to their own judgement. * Each member has an equal vote. * The members at the meeting act for the entire group, even if there are members absent. * A member's dissent on a particular issue constitutes neither a withdrawal from the group, nor a termination of membership.
