Crowds
Generally speaking, a crowd is defined as a group of people that have gathered for a common purpose or intent such as at a demonstration, a sports event, or during looting (this is known as an acting crowd), or may simply be made up of many people going about their business in a busy area. The term "the crowd" may sometimes refer to the lower orders of people in general. Terminology The term "crowd" is sometimes defined in contrast to other group nouns for collections of humans or animals, such as aggregation, audience, group, mass, mob, populous, public, rabble and throng. Opinion researcher Vincent Price compares masses and crowds, saying that "Crowds are defined by their shared emotional experiences, but masses are defined by their interpersonal isolation."Public Opinion By Carroll J. Glynn, Susan Herbst, Garrett J. O'Keefe, Robert Y. Shapiro In human sociology, the term "mobbed" simply means "extremely crowded", as in a busy mall or shop. "Mobbing", carries a more nega ...

Crowdsourcing
Crowdsourcing involves a large group of dispersed participants contributing or producing goods or services—including ideas, votes, micro-tasks, and finances—for payment or as volunteers. Contemporary crowdsourcing often involves digital platforms to attract and divide work between participants to achieve a cumulative result. Crowdsourcing is not limited to online activity, however, and there are various historical examples of crowdsourcing. The word crowdsourcing is a portmanteau of "crowd" and " outsourcing". In contrast to outsourcing, crowdsourcing usually involves less specific and more public groups of participants. Advantages of using crowdsourcing include lowered costs, improved speed, improved quality, increased flexibility, and/or increased scalability of the work, as well as promoting diversity. Crowdsourcing methods include competitions, virtual labor markets, open online collaboration and data donation. Some forms of crowdsourcing, such as in "idea competiti ...

Crowd Psychology
Crowd psychology, also known as mob psychology, is a branch of social psychology. Social psychologists have developed several theories for explaining the ways in which the psychology of a crowd differs from and interacts with that of the individuals within it. Major theorists in crowd psychology include Gustave Le Bon, Gabriel Tarde and Sigmund Freud. This field relates to the behaviors and thought processes of both the individual crowd members and the crowd as an entity. Crowd behavior is heavily influenced by the loss of responsibility of the individual and the impression of universality of behavior, both of which increase with crowd size. Origins The first debate in crowd psychology began in Rome at the first International Congress of Criminal Anthropology on 16 November 1885. The meeting was dominated by Cesare Lombroso and his fellow Italians, who emphasized the biological determinates. : "Lombroso detailed before the first congress his theories of the physical anomalies ...

Crowd Manipulation
Crowd manipulation is the intentional or unwitting use of techniques based on the principles of crowd psychology to engage, control, or influence the desires of a crowd in order to direct its behavior toward a specific action. This practice is common to religion, politics and business and can facilitate the approval or disapproval or indifference to a person, policy, or product. The ethicality of crowd manipulation is commonly questioned. Crowd manipulation differs from propaganda—although they may reinforce one another to produce a desired result. If propaganda is "the consistent, enduring effort to create or shape events to influence the relations of the public to an enterprise, idea or group", crowd manipulation is the relatively brief call to action once the seeds of propaganda (i.e. more specifically "pre-propaganda") are sown and the public is organized into a crowd. The propagandist appeals to the masses, even if compartmentalized, whereas the crowd-manipulator appeals ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crowd Simulation
Crowd simulation is the process of simulating the movement (or ) of a large number of entities or characters. It is commonly used to create virtual scenes for visual media like films and video games, and is also used in crisis training, architecture and urban planning, and evacuation simulation. Crowd simulation may focus on aspects that target different applications. For realistic and fast rendering of a crowd for visual media or virtual cinematography, reduction of the complexity of the 3D scene and image-based rendering are used, while variations (changes) in appearance help present a realistic population. In games and applications intended to replicate real-life human crowd movement, like in evacuation simulations, simulated agents may need to navigate towards a goal, avoid collisions, and exhibit other human-like behavior. Many crowd steering algorithms have been developed to lead simulated crowds to their goals realistically. Some more general systems are researched that ...

Crowd Funding
Crowdfunding is the practice of funding a project or venture by raising money from a large number of people, typically via the internet. Crowdfunding is a form of crowdsourcing and alternative finance. In 2015, over was raised worldwide by crowdfunding. Although similar concepts can also be executed through mail-order subscriptions, benefit events, and other methods, the term crowdfunding refers to internet-mediated registries. This modern crowdfunding model is generally based on three types of actors – the project initiator who proposes the idea or project to be funded, individuals or groups who support the idea, and a moderating organization (the "platform") that brings the parties together to launch the idea. Crowdfunding has been used to fund a wide range of for-profit, entrepreneurial ventures such as artistic and creative projects, medical expenses, travel, and community-oriented social entrepreneurship projects. Although crowdfunding has been suggested to be highly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crowd Counting
Conventional understanding of Crowd Counting: Crowd counting is known to be act of counting the total crowd present in a certain area. The people in a certain area are called a crowd. The most direct method is to actually count each person in the crowd. For example, turnstiles are often used to precisely count the number of people entering an event. Modern understanding Since the early 2000s, there has been a shift in the understanding of the phrase “crowd counting”. Having moved from a simpler crowd counting method to that of clusters and density maps, there are several improvements for crowd counting methods. Crowd counting can also be defined as estimating the number of people present in a single picture Methods of counting crowds Due to the rapid progress in technology and growth of CNN (Convolutional Neural Network) over the last decade, the usage of CNN in crowd counting has skyrocketed. The CNN based methods can largely be grouped under the following different mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crowd Crush
Crowd collapses and crushes are catastrophic incidents that can occur when a body of people becomes dangerously overcrowded. When a body of people reaches or exceeds the density of , the pressure on each individual can cause the crowd to collapse in on itself, or become so densely packed that individuals are crushed and asphyxiated. At this density, a crowd can start to act like fluid, sweeping individuals around without their volition. Such incidents are invariably the product of failures of organizations, and most major crowd disasters can be prevented by simple crowd management strategies. Such incidents can occur at large gatherings such as sporting, commercial, social, and religious events. The critical factor is crowd density rather than crowd size. Background One study has calculated that there were 232 deaths and over 66,000 injuries in the ten years between 1992 and 2002, and it is believed by crowd scientists that such incidents are both vastly under-reported and ...

Collective Animal Behavior
Collective animal behaviour is a form of social behavior involving the coordinated behavior of large groups of similar animals as well as emergent properties of these groups. This can include the costs and benefits of group membership, the transfer of information, decision-making process, locomotion and synchronization of the group. Studying the principles of collective animal behavior has relevance to human engineering problems through the philosophy of biomimetics. For instance, determining the rules by which an individual animal navigates relative to its neighbors in a group can lead to advances in the deployment and control of groups of swimming or flying micro-robots such as UAVs (Unmanned Aerial Vehicles). Examples Examples of collective animal behavior include: * Flocking birds * Herding ungulates * Shoaling and schooling fish * Schooling Antarctic krill * Pods of dolphins * Marching locusts * Nest building ants * Swarming * Stampede History The basis of collect ...

Crowd Control
Crowd control is a public security practice in which large crowds are managed in order to prevent the outbreak of crowd crushes, affray, fights involving drunk and disorderly people or riots. Crowd crushes in particular can cause many hundreds of fatalities. Effective crowd management is about managing expected and unexpected crowd occurrences. Crowd control can involve privately hired security guards as well as police officers. Crowd control is often used at large, public gatherings like street fairs, music festivals, stadiums and public demonstrations. At some events, security guards and police use metal detectors and sniffer dogs to prevent weapons and drugs being brought into a venue. Equipment Materials such as stanchions, crowd control barriers, fences and decals painted on the ground can be used to direct a crowd. A common method of crowd control is to use high visibility fencing to divert and corral pedestrian traffic to safety when there is any potential threat for ...

Riot
A riot is a form of civil disorder commonly characterized by a group lashing out in a violent public disturbance against authority, property, or people. Riots typically involve destruction of property, public or private. The property targeted varies depending on the riot and the inclinations of those involved. Targets can include shops, cars, restaurants, state-owned institutions, and religious buildings. Riots often occur in reaction to a grievance or out of dissent. Historically, riots have occurred due to poverty, unemployment, poor living conditions, governmental oppression, taxation or conscription, conflicts between ethnic groups ( race riot) or religions (sectarian violence, pogrom), the outcome of a sporting event (sports riot, football hooliganism) or frustration with legal channels through which to air grievances. While individuals may attempt to lead or control a riot, riots typically consist of disorganized groups that are frequently "chaotic and exhibit herd be ...

Agent-based Social Simulation
Agent-based social simulation (or ABSS) consists of social simulations that are based on agent-based modeling, and implemented using artificial agent technologies. Agent-based social simulation is a scientific discipline concerned with simulation of social phenomena, using computer-based multiagent models. In these simulations, persons or group of persons are represented by agents. MABSS is a combination of social science, multiagent simulation and computer simulation. ABSS models the different elements of the social systems using artificial agents, (varying on scale) and placing them in a computer simulated society to observe the behaviors of the agents. From this data it is possible to learn about the reactions of the artificial agents and translate them into the results of non-artificial agents and simulations. Three main fields in ABSS are agent-based computing, social science, and computer simulation. Agent-based computing is the design of the model and agents, while the c ...
