Moving back a stage on the social movement -organizational model, calls attention to one way which social movement organizations and more emergent forms of collective behavior may be related. The temporally sequential relation noted previously, where social movements use crowds and attempt to reach mass audiences may be reversed. The Visual Model Editor. The STEM Visual Model Editor is a new tool that allows scientists to describe the structure - and mathematics - behind their computational model in an easy to use graphical user interface. Getting Started With the Visual Model Editor. The Visual Model Editor is a tool for visual designing compartment models.

Dark Mode
In macOS 10.14 and later, users can choose to adopt a dark system-wide appearance instead of a light appearance. In Dark Mode, the system adopts a darker color palette for all windows, views, menus, and controls. The system also uses more vibrancy to make foreground content stand out against the darker backgrounds.

Focus on your content. Dark Mode puts the focus on the content areas of your interface, allowing that content to stand out while the surrounding chrome recedes into the background.
Dark Mode is an aesthetic choice for users. Users can choose Dark Mode as their default interface style, and may use it at any time of day or in any lighting conditions.
Test your design in both light and dark appearances. See how your interface looks in both appearances, and adjust your designs as needed to accommodate each one. In Dark Mode, see how your designs look when Desktop Tinting is active. Decisions that work well in one appearance might not work in the other.
Adopt vibrancy in your interfaces. Vibrancy improves the contrast between foreground and background colors, making your foreground content appear more prominent. See Translucency and Vibrancy.
Colors
The color palette in Dark Mode includes darker background colors and lighter foreground colors. These colors aren’t necessarily an inversion of their light counterparts. While many colors are inverted, some are not. For example, both light and dark appearances use dark lines to create visual separations between views.
Embrace colors that adapt to the current appearance. Semantic colors (like labelColor and controlColor) adapt to the current appearance automatically. When you need a custom color, add a Color Set asset to your app’s asset catalog and specify the light and dark variants of the color. Avoid using hard-coded color values or colors that don’t adapt.
Ensure sufficient color contrast in all appearances. Using system-defined colors ensures a proper contrast ratio between your foreground and background content. For custom foreground and background colors, strive for a contrast ratio of 7:1. This ratio ensures that your foreground content stands out from the background, including when Desktop Tinting is active. It also ensures that your content meets more stringent accessibility guidelines. At a minimum, make sure the contrast ratio between colors is no lower than 4.5:1.
Soften the color of white backgrounds. If you must use a white background for your content in Dark Mode, choose a slightly darker white that prevents the background from glowing against the surrounding dark content.
For related guidance, including information about color accessibility standards, see Color and Contrast.
Desktop Tinting
Apps running in Dark Mode benefit from Desktop Tinting. When active, Desktop Tinting causes window backgrounds to pick up color from the user's desktop picture. The result is a subtle tinting effect that helps windows blend more harmoniously with their surrounding content. Users who prefer not to have the additional tinting, perhaps because they work with color-sensitive content, can disable this effect by choosing the graphite accent color in System Preferences.
Include some transparency in custom control colors. Transparency lets your controls pick up color imparted by the window background and by Desktop Tinting. That additional color creates a harmony between your controls and backgrounds, which persists even when the desktop picture changes.
Images, Icons, and Glyphs
The system makes extensive use of template images in Dark Mode. A template image is a monochromatic image with transparency, anti-aliasing, and no drop shadow that uses a mask to define its shape. The system also includes many full-color images that are optimized for both light and dark appearances.
Use template images wherever possible. Template images adapt to light and dark interfaces, and they can take full advantage of vibrancy. Full-color images that look good in one interface might look washed out in another. For related guidance, see Custom Icons.
Design individual glyphs for light and dark appearances when necessary. A glyph that uses a hollow outline in light mode might look better as a solid, filled shape in Dark Mode.

Make sure full-color images look good. Use the same asset if it looks good in both light and dark appearances. If an asset looks good in only one appearance, modify the asset or create separate light and dark assets. Use asset catalogs to combine your assets into a single, named image.
Typography
The system uses vibrancy and increased contrast to maintain the legibility of text on darker backgrounds.
Use the system-provided label colors for text. The primary, secondary, tertiary, and quaternary label colors adapt automatically to light and dark appearances. For related guidance, see Typography.
Use system views to draw static text. System views and controls make your app’s text look good on all backgrounds, adjusting automatically for the presence or absence of vibrancy. Don’t draw text yourself when you could use a system-provided view to display that text instead. See NSTextField and NSTextView.
Social Change
Collective behavior can result in social change through the formation of cohesive social movements.

Key Takeaways
Key Points
- Collective behavior can be distinguished from group behavior, and it is also distinct from deviant and conforming actions.
- Collective behavior can be observed in four types of groupings of people: the crowd, the mass, the public, and social movements, although other phenomena, such as fads and rumors, are also considered to be forms of collective behavior.
- Studying collective behavior improves our understanding of how to organize social movements to initiate social change.
- There are two main reasons for studying collective behavior. First, to reduce the damage caused by events such as natural disasters and riots by understanding how people behave in these situations; second, studying collective behavior improves our understanding of how to organize social movements in order to initiate social change.
- A crowd is an assembly of people who come together with a shared purpose or intent, and have an influence over one another. The four type of crowds, as identified by Herbert Blumer, are casual, conventional, expressive and acting. Diffuse crowds are crowds that are scattered across large distances.
- Posited by Gustave Lebon in 1896, contagion theory asserts that crowds have a hypnotic influence over their members, which, combined with the anonymity that individuals in a crowd can enjoy, leads to irrational and emotional behavior.
- Convergence Theory proposes that crowd behavior is the product of like-minded individuals coming together and is not an inherent characteristic of the crowd itself.
- A combination of the theories of convergence and contagion, the emergent- norm theory states that crowd behavior is the product of the convergence of like-minded people, the sense of anonymity in a crowd and shared emotions. Underlying this theory is the symbolic-interactionist perspective.
- Understanding crowds as “gatherings,” which are temporary and are formed by an assembling process, allows us to create a distinction between what causes people to gather and what actions they take once they have gathered. Moreover, seeings crowds as gatherings also refutes the idea that crowds can impair judgment.
- A panic is a sudden terror which dominates thinking and can affect groups of people. A moral panic is a mass movement that arises when an invidual or group, frequently a minority or subculture, is perceived to be a threat to society.
- A riot is a form of civil disorder that is characterized by disorganized groups lashing out and disturbing the peace in a sudden and intense rash of violence, vandalism or other crime. Riots typically reflect grievance or a sense of dissatisfaction with existing conditions. Unlike a mob, a riot is violent crowd behavior without a specific objective.
- “Mass hysteria” is a phrase used to describe a large group of people who share a mental state of fear or anxiety.
- A fad is a fashion that gains salience quickly in a culture or subculture, and remains popular for a brief period of time before losing its appeal dramatically.
- A rumor is an unverified account or explanation of events circulating from person to person and pertaining to an object, event, or issue in public concern.
Key Terms
- riot: Wanton or unrestrained behavior; uproar; tumult.
- Collective behavior: The expression collective behavior was first used by Robert E. Park, and employed definitively by Herbert Blumer, to refer to social processes and events which do not reflect existing social structure (laws, conventions, and institutions), but which emerge in a “spontaneous” way.
Collective behavior refers to social processes and events that do not reflect existing social structure (laws, conventions, and institutions), as they emerge in a “spontaneous” way. Collective behavior might also be defined as action that is neither conforming (in which actors follow prevailing norms) nor deviant (in which actors violate those norms). Rather, collective behavior, a third form of action, takes place when norms are absent or unclear, or when they contradict each other. Scholars have devoted far less attention to collective behavior than they have to either conformity or deviance.
Examples of collective behavior include: religious revival meetings (like those depicted in the documentary Marjoe), a panic in a burning theater (e.g., the Kentucky Beverly Hills Supper Club fire), a sudden widespread interest in a website (e.g., MySpace) or clothing item (e.g., WristStrong bracelets), a collective social movement to improve the environment (e.g., Greenpeace), or the rapid spread of rumors (e.g., that Barack Obama is Muslim or not a US citizen). These diverse actions fall within the area sociologists call collective behavior.

Collective behavior differs from group behavior in three ways:
![Mac Mac](https://img.itch.zone/aW1hZ2UvNTU4OTg3LzI5MzQxMzcucG5n/original/maucCQ.png)
- Collective behavior involves limited and short-lived social interactions, while groups tend to remain together longer.
- Collective behavior has no clear social boundaries; anyone can be a member of the collective, while group membership is usually more discriminating.
- Collective behavior generates weak and unconventional norms, while groups tend to have stronger and more conventional norms.
Traditionally in sociology, collective behavior is displayed by four types of groupings of people: the crowd, the public, the mass, and the social movement. While there is debate over what should be included under the label of “collective behavior” among sociologists today, often included are additional behaviors like: rumors, riots, and fads.

Collective Behavior and Social Change
Collective behavior can actually change elements of society. This is the component of collective behavior known as “social movements. ”

On March 7, 1965, African American leaders led a march of 600 people in an attempt to walk the 54 miles (87 km) from Selma to the state capital in Montgomery. Only six blocks into the march, however, state troopers and local law enforcement attacked the peaceful demonstrators with billy clubs, tear gas, rubber tubes wrapped in barbed wire, and bull whips. They drove the marchers back to Selma. The national broadcast showing footage of lawmen attacking unresisting marchers seeking the right to vote provoked a national response. Eight days after the first march, Lyndon Johnson delivered a televised address to garner support for the voting rights bill he had sent to Congress. In it he stated:
But even if we pass this bill, the battle will not be over. What happened in Selma is part of a far larger movement which reaches into every section and state of America. It is the effort of American Negroes to secure for themselves the full blessings of American life. Their cause must be our cause too. Because it is not just Negroes, but really it is all of us, who must overcome the crippling legacy of bigotry and injustice. And we shall overcome.
Johnson signed the Voting Rights Act of 1965 on August 6. The 1965 Act suspended poll taxes, literacy tests, and other subjective voter tests. It authorized Federal supervision of voter registration in states and individual voting districts where such tests were being used. The act had an immediate and positive impact for African Americans. Within months of its passage, 250,000 new black voters had been registered. Within four years, voter registration in the South had more than doubled.
Understanding how to organize a social movement to pursue social change is one of the areas studied by sociologists. The insights gained from these studies can provide movement members the tools they need to succeed.

Riots
A riot is a form of civil disorder characterized by disorganized groups lashing out in a sudden and intense rash of violence, vandalism, or other crime. While individuals may attempt to lead or control a riot, riots are typically chaotic and exhibit herd-like behavior. Riots often occur in reaction to a perceived grievance or out of dissent. Historically, riots have occurred due to poor working or living conditions, government oppression, taxation or conscription, conflicts between races or religions, the outcome of a sporting event, or frustration with legal channels through which to air grievances. Riots typically involve vandalism and the destruction of private and public property. Riots, while destructive, have often played a role in social change.
