Three Degrees Of Influence
Three degrees of influence is a theory in the realm of social networks, proposed by Nicholas A. Christakis and James H. Fowler in 2007. This argument is basically that peer effects need not stop at one degree of separation. Rather, across a broad set of empirical settings, using both observational and experimental methods, it has been observed that the effect seems, in many cases, to no longer be meaningful at a social horizon of three degrees. The theory has since been explored by scientists in numerous disciplines using diverse statistical, mathematical, psychological, sociological, and biological approaches. Numerous large-scale in-person and online experiments have documented this phenomenon in the intervening years. Beginning in the early 2000's, Christakis and Fowler explored the impact of social connections on behavior, describing how social influence and social contagion do not end with the people to whom a person is directly connected. People influence their friends, who ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Network
A social network is a social structure consisting of a set of social actors (such as individuals or organizations), networks of Dyad (sociology), dyadic ties, and other Social relation, social interactions between actors. The social network perspective provides a set of methods for analyzing the structure of whole social entities along with a variety of theories explaining the patterns observed in these structures. The study of these structures uses social network analysis to identify local and global patterns, locate influential entities, and examine dynamics of networks. For instance, social network analysis has been used in studying the spread of misinformation on social media platforms or analyzing the influence of key figures in social networks. Social networks and the analysis of them is an inherently Interdisciplinarity, interdisciplinary academic field which emerged from social psychology, sociology, statistics, and graph theory.

Randomized Controlled Trial
A randomized controlled trial (or randomized control trial; RCT) is a form of scientific experiment used to control factors not under direct experimental control. Examples of RCTs are clinical trials that compare the effects of drugs, surgical techniques, medical devices, diagnostic procedures, diets or other medical treatments. Participants who enroll in RCTs differ from one another in known and unknown ways that can influence study outcomes, and yet cannot be directly controlled. By randomly allocating participants among compared treatments, an RCT enables ''statistical control'' over these influences. Provided it is designed well, conducted properly, and enrolls enough participants, an RCT may achieve sufficient control over these confounding factors to deliver a useful comparison of the treatments studied. Definition and examples An RCT in clinical research typically compares a proposed new treatment against an existing standard of care; these are then termed the 'expe ...

Influence Of Mass Media
In media studies, mass communication, media psychology, communication theory, and sociology, media influence and the media effect are topics relating to mass media and media culture's effects on individuals' or audiences' thoughts, attitudes, and behaviors. Through written, televised, or spoken channels, mass media reach large audiences. Mass media's role in shaping modern culture is a central issue for the study of culture. Media influence is the actual force exerted by a media message, resulting in either a change or reinforcement in audience or individual beliefs. Whether a media message has an effect on any of its audience members is contingent on many factors, including audience demographics and psychological characteristics. These effects can be positive or negative, abrupt or gradual, short-term or long-lasting. Not all effects result in change; some media messages reinforce an existing belief. Researchers examine an audience after media exposure for changes in cognition, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public Opinion
Public opinion, or popular opinion, is the collective opinion on a specific topic or voting intention relevant to society. It is the people's views on matters affecting them. In the 21st century, public opinion is widely thought to be heavily influenced by the media; many studies have been undertaken which look at the different factors which influence public opinion. Politicians and other people concerned with public opinion often attempt to influence it using advertising or rhetoric. Opinion plays a vital role in uncovering some critical decisions. Sentiment analysis or opinion mining is a method used to mine the thoughts or feelings of the general population. One of the struggles of public opinion is how it can be influenced by misinformation. Etymology The term "public opinion" was derived from the French ', which was first used in 1588 by Michel de Montaigne, one of the most significant philosophers of the French Renaissance, in the second edition of his famous '' Essays ...

Sociological Theories
Sociology is the scientific study of human society that focuses on society, human social behavior, patterns of social relationships, social interaction, and aspects of culture associated with everyday life. The term sociology was coined in the late 18th century to describe the scientific study of society. Regarded as a part of both the social sciences and humanities, sociology uses various methods of empirical investigation and critical analysis to develop a body of knowledge about social order and social change. Sociological subject matter ranges from micro-level analyses of individual interaction and agency to macro-level analyses of social systems and social structure. Applied sociological research may be applied directly to social policy and welfare, whereas theoretical approaches may focus on the understanding of social processes and phenomenological method. Traditional focuses of sociology include social stratification, social class, social mobility, religion, sec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Tipping Point
''The Tipping Point: How Little Things Can Make a Big Difference'' is the debut book by Malcolm Gladwell, first published by Little, Brown in 2000. Gladwell defines a tipping point as "the moment of critical mass, the threshold, the boiling point." The book seeks to explain and describe the "mysterious" sociological changes that mark everyday life. As Gladwell states: "Ideas and products and messages and behaviors spread like viruses do." The examples of such changes in his book include the rise in popularity and sales of Hush Puppies shoes in the mid-1990s and the steep drop in New York City's crime rate after 1990. The three rules Gladwell describes the "three rules of epidemics" (or the three "agents of change") in the tipping points of epidemics. The Law of the Few "The Law of the Few" is, as Gladwell states: "The success of any kind of social epidemic is heavily dependent on the involvement of people with a particular and rare set of social gifts." According to Gladwell, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Six Degrees Of Separation
Six degrees of separation is the idea that all people are six or fewer social connections away from each other. As a result, a chain of "friend of a friend" statements can be made to connect any two people in a maximum of six steps. It is also known as the six handshakes rule. Mathematically it means that a person shaking hands with 30 people, and then those 30 shaking hands with 30 other people, would after repeating this six times allow every person in a population as large as the United States to have shaken hands (seven times for the whole world). The concept was originally set out in a 1929 short story by Frigyes Karinthy, in which a group of people play a game of trying to connect any person in the world to themselves by a chain of five others. It was popularized in John Guare's 1990 play ''Six Degrees of Separation (play), Six Degrees of Separation''. The idea is sometimes generalized to the average Path (graph theory), social distance being logarithmic in the size of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Free Will
Free will is generally understood as the capacity or ability of people to (a) choice, choose between different possible courses of Action (philosophy), action, (b) exercise control over their actions in a way that is necessary for moral responsibility, or (c) be the ultimate source or originator of their actions. There are different theories as to its nature, and these aspects are often emphasized differently depending on philosophical tradition, with debates focusing on whether and how such freedom can coexist with determinism, divine foreknowledge, and other constraints. Free will is closely linked to the concepts of moral responsibility, praise, culpability, and other judgements which apply only to actions that are freely chosen. It is also connected with the concepts of Advice (opinion), advice, persuasion, deliberation, and Prohibitionism, prohibition. Traditionally, only actions that are freely Will (philosophy), willed are seen as deserving credit or blame. Whether free ...
