1. The Sign Formula | 符号公式
A sign is the fundamental unit of meaning in semiotics. According to Saussure, every sign is composed of two parts that cannot be separated: the physical form and the mental concept it triggers.
符号是符号学中意义的基本单位。根据索绪尔的理论，每一个符号都由不可分割的两部分组成：物理形式及其引发的心理概念。
Sign = Signifier + Signified
In media texts, the signifier is the image, word or sound we perceive; the signified is the idea or meaning it evokes. For example, a red rose (signifier) may signify romance or love (signified). Barthes added layers by proposing that denotation (literal meaning) leads to connotation (cultural associations) and eventually to myth (ideological meaning).
在媒介文本中，能指是我们感知到的图像、文字或声音；所指是其唤起的观念或意义。例如，一朵红玫瑰（能指）可以表示浪漫或爱情（所指）。巴特增加了层次，提出外延（字面意义）通向内涵（文化联想），并最终通向神话（意识形态意义）。
Denotation → Connotation → Myth
Peirce further classified signs into three types: icon (resembles what it stands for), index (has a direct causal link) and symbol (arbitrary, learned connection). These formulas help you break down any media product into its meaningful parts.
皮尔斯进一步将符号分为三类：像似符（与其所指相似）、指示符（有直接的因果联系）和象征符（任意、习得的联系）。这些公式帮助你将任何媒介产品分解为有意义的组成部分。
2. Todorov’s Equilibrium Formula | 托多罗夫平衡公式
Narrative is not random; it follows a structure. Todorov’s theory describes the journey of a story as a disturbance to an initial state of balance and the eventual restoration of a new order. This can be written as a dynamic equation.
叙事并非随机；它遵循一种结构。托多罗夫的理论将故事旅程描述为对初始平衡状态的干扰以及最终新秩序的恢复。这可以写成一个动态方程。
Equilibrium → Disruption → Recognition → Attempt to Repair → New Equilibrium
The initial equilibrium presents a stable, calm world. A disruption (an event or villain) breaks that stability. Recognition occurs when characters realise the disruption, leading to an attempt to repair the damage. The narrative ends with a new equilibrium, which is different from the first but restores harmony. This formula is evident in countless films, TV dramas and even news stories.
初始平衡呈现一个稳定、平静的世界。破坏（某个事件或反派）打破了这种稳定。当角色意识到破坏时便形成认知，继而引发修复损害的尝试。叙事以一个不同于最初但恢复了和谐的新平衡结束。这一公式可见于无数电影、电视剧甚至新闻故事中。
When analysing a set text, ask: What is the initial equilibrium? Who or what causes the disruption? Is the new equilibrium truly resolved, or does it leave questions? Todorov’s formula helps you identify ideological closures and narrative expectations in mainstream media.
分析指定文本时，请问：初始平衡是什么？谁或什么造成了破坏？新平衡是否真正得以解决，还是留下了疑问？托多罗夫的公式帮助你识别主流媒介中的意识形态闭合和叙事期待。
3. Propp’s Character Function Theorem | 普罗普角色功能定理
Vladimir Propp analysed folk tales and identified a set of recurring character roles, or ‘functions’, that drive the plot. These can be thought of as variables in a narrative equation. While originally applied to fairy tales, they appear across contemporary media.
弗拉基米尔·普罗普分析了民间故事，识别出一系列推动情节的反复出现的角色类型，或称“功能”。它们可以被视为叙事方程中的变量。虽然最初应用于童话故事，但它们广泛出现在当代媒介中。
The classic formula includes:
经典公式包括：
- Hero – the protagonist who seeks something.
- 英雄 – 寻求某物的主角。
- Villain – opposes the hero.
- 反派 – 对抗英雄。
- Dispatcher – sends the hero on the quest.
- 派遣者 – 派英雄踏上征程。
- Helper – aids the hero.
- 帮手 – 帮助英雄。
- Princess/Prize – the object of the hero’s desire.
- 公主/奖赏 – 英雄渴望的对象。
- Donor – provides a magical object or knowledge.
- 赠与者 – 提供神奇物品或知识。
- False Hero – claims credit for the hero’s actions.
- 伪英雄 – 声称英雄的功劳为己有。
In a superhero film, for instance, the villain disrupts peace, the dispatcher (e.g. a chief) mobilises the hero, a helper (sidekick) assists, and the prize (saving the city) is won. Propp’s theorem reminds us that characters in media are often not individuals but narrative functions designed to move the story forward.
例如，在一部超级英雄电影中，反派破坏和平，派遣者（如长官）动员英雄，帮手（助手）协助，而奖赏（拯救城市）被获得。普罗普的定理提醒我们，媒介中的角色往往并非独立的个体，而是为推动故事而设计的叙事功能。
4. Levi-Strauss’ Binary Oppositions Theorem | 列维-斯特劳斯二元对立定理
Meanings in media are often constructed through conflict between opposing forces. Claude Levi-Strauss argued that narratives are organised around binary oppositions – pairs of mutually exclusive concepts that structure our understanding of the world.
媒介中的意义往往通过对立力量之间的冲突建构。克洛德·列维-斯特劳斯认为叙事是围绕二元对立组织起来的——成对相互排斥的概念塑造了我们对世界的理解。
eaning = Conflict between Opposites (e.g. Good vs Evil, Civilised vs Savage, Young vs Old)
These oppositions are not neutral; one side is usually privileged or valued over the other, reinforcing dominant ideologies. In a Western, the opposition might be settler vs Native American, with the settler often presented as civilised and the Native as savage, reinforcing a colonial worldview.
这些对立并非中立；通常有一方被置于优越或更有价值的地位，从而强化主流意识形态。在西部片中，对立可能是定居者与原住民，定居者往往被表现为文明，原住民被表现为野蛮，从而强化殖民世界观。
To apply this theorem, map the key binary pairs in a media text. Look at visual codes, dialogue and editing: who is framed as the ‘us’ and who as the ‘them’? Examining these oppositions exposes the hidden ideologies that shape the narrative.
应用此定理时，找出媒介文本中的关键二元对。观察视觉编码、对话和剪辑：谁被界定为“我方”，谁被界定为“他者”？审视这些对立能够揭示塑造叙事的隐蔽意识形态。
5. Representation Theorem: Stereotype and Encoding/Decoding | 表征定理：刻板印象与编码/解码
Media representations are not reality; they are a construction. Stuart Hall’s encoding/decoding model explains how producers encode meanings and audiences decode them. The formula captures the communication process and the possible readings.
媒介表征不是现实；它们是建构之物。斯图亚特·霍尔的编码/解码模型解释了生产者如何编码意义、受众如何解码。公式概括了传播过程及可能的解读。
Encoded Meaning → Text → Audience’s Decoded Meaning (Dominant / Negotiated / Oppositional)
A dominant (or preferred) reading accepts the intended message. A negotiated reading partly accepts but modifies it to fit personal experience. An oppositional reading rejects the preferred meaning entirely. For example, an advertisement encoded to promote a beauty ideal might be decoded oppositionally by an audience aware of its unrealistic standards.
主导（或倾向性）解读接受所意图的信息。协商式解读部分接受，但根据个人经验加以修正。对抗式解读则完全拒斥倾向性意义。例如，一则旨在推广某种美容理想的广告可能被意识到其不切实际标准的受众以对抗式解读。
Representation also relies on stereotypes – simplified, often exaggerated descriptions of social groups. The stereotype formula reduces complexity: a few selected traits become the whole story. This ties directly to power: those with less power are more likely to be stereotyped.
表征还依赖于刻板印象——对社会群体的简化、往往夸大的描述。刻板印象公式将复杂性简化为：少数被选中的特征成为全部故事。这直接与权力相关：权力较弱者更容易被刻板印象化。
6. Uses and Gratifications Formula | 使用与满足公式
Instead of asking ‘what media do to people’, the uses and gratifications model asks ‘what do people do with media’. The theory is expressed as a set of needs that audiences actively seek to fulfil through media consumption.
与关注“媒介对人们做了什么”不同，使用与满足模型探究“人们用媒介做了什么”。该理论被表述为一组受众通过媒介消费积极寻求满足的需求。
Use = Information + Personal Identity + Integration and Social Interaction + Entertainment
Information (or surveillance) satisfies the need to know about the world. Personal identity uses media to reinforce values and find role models. Integration and social interaction provides a basis for conversation and belonging. Entertainment offers escape and relaxation. Each media text can gratify multiple needs simultaneously – a TV drama might inform, offer characters to identify with and entertain.
信息（或监视）满足了解世界的需求。个人身份利用媒介来强化价值观并寻找榜样。融合与社会互动提供了对话和归属感的基础。娱乐则提供逃避和放松。每则媒介文本可以同时满足多种需求——一部电视剧可以既提供信息，又提供可认同的角色，并带来娱乐。
To use this formula in an exam, identify which needs a specific text is likely to gratify and why the target audience might choose it. A teen magazine, for example, may gratify personal identity and social interaction through relatable content and shareable quizzes.
要在考试中应用此公式，请识别某一特定文本可能满足哪些需求，以及目标受众为何选择它。例如，一本青少年杂志可能通过可共鸣的内容和可分享的测验满足个人身份和社交互动的需求。
7. Media Effects Theorems: Cultivation and Hypodermic Needle | 媒介效果定理：涵化与皮下注射
While uses and gratifications sees audiences as active, effects theories consider the power of media to influence passive viewers. Two classical theorems are still examinable: the hypodermic needle model and cultivation theory.
当使用与满足理论将受众视为主动者时，效果理论则关注媒介对被动观众的影响力。两个经典定理仍在考试范围内：皮下注射模式和涵化理论。
The Hypodermic Needle Theorem assumes a direct, immediate effect:
皮下注射定理假定直接、即时的效果：
Media Message → Passive Audience → Immediate, Uniform Effect
It suggests media injects ideas straight into the minds of the public, like a drug. This model often appears in moral panics about violent video games or harmful online content. Modern media scholars largely reject it as too simplistic.
它认为媒介像药物一样，将思想直接注入公众头脑。这种模式常出现在关于暴力电子游戏或有害网络内容的道德恐慌中。现代媒介学者普遍认为它过于简单而予以否定。
Cultivation Theorem (Gerbner) offers a long-term perspective:
涵化定理（葛伯纳）提供了一个长期视角：
Heavy Media Exposure → Shaped Perception of Reality (Mean World Syndrome)
Heavy viewers of television, for example, may begin to perceive the real world as more dangerous than it is, a phenomenon known as ‘mean world syndrome’. This theorem emphasises cumulative, gradual influence rather than a single message.
例如，重度电视观众可能开始将现实世界感知得比实际情况更危险，这一现象被称为“邪恶世界综合征”。该定理强调累积的、渐进的影响，而非单条讯息的作用。
8. Industry and Ownership Integration Formulas | 产业与所有权整合公式
Media industries operate through structures that reduce risk and maximise profit. The concentration of ownership follows two key formulas: vertical integration and horizontal integration.
媒介产业通过降低风险和最大化利润的结构运作。所有权的集中遵循两个关键公式：垂直整合和水平整合。
Vertical Integration = Owning Stages of Production + Distribution + Exhibition
A vertically integrated company controls the entire supply chain. For instance, a film studio that produces a movie, distributes it through its own network and screens it in its own cinemas. This secures control and recoups costs at every stage.
垂直整合的公司控制整个供应链。例如，一家电影制片厂制作电影，通过自己的网络发行并在自有影院放映。这确保了对每一阶段的控制并回收成本。
Horizontal Integration = Owning Multiple Companies at the Same Stage of Production
A horizontally integrated conglomerate owns several brands, studios or publications that operate at the same level, such as a corporation that buys multiple music labels or magazine titles. This widens market share and reduces competition.
水平整合的企业集团在同一生产阶段拥有多个品牌、制片厂或出版物，例如一家公司收购多家音乐厂牌或杂志刊号。这扩大了市场份额并减少了竞争。
Conglomeration, synergy and cross-media ownership are extensions of these formulas. Synergy means different parts of a conglomerate work together to promote a product across platforms, maximising revenue from a single idea.
集团化、协同效应和跨媒体所有权是这些公式的延伸。协同意味着集团不同部分共同跨平台推广产品，从单一创意中最大化收益。
9. Convergence and Cross-Platform Formula | 融合与跨平台公式
Technological convergence has blurred the lines between media devices and platforms. The convergence formula describes how previously separate media forms and industries now interconnect.
技术融合已经模糊了媒介设备与平台之间的界限。融合公式描述了此前分离的媒介形式和产业如今如何相互连接。
echnological Convergence = Mobile + Internet + Broadcasting + Print Combined in One Device
A smartphone exemplifies convergence: it is a telephone, camera, television, games console and newspaper all in one. This changes not only consumption but also production and distribution, as content flows across platforms.
智能手机就是融合的范例：它将电话、相机、电视、游戏机和报纸合为一体。这不仅改变了消费方式，也改变了生产和发行方式，因为内容可以在各平台间流动。
The cross-platform formula captures how media brands now use multiple channels:
跨平台公式概括了媒介品牌如今如何利用多种渠道：
dia = Content Released on TV + Web + Social Media + Print + App (Unified Brand Experience)
An example is a TV drama that has alternative reality games on its website, character social media profiles and behind-the-scenes podcasts. This intensifies audience engagement and allows audiences to interact with the text in diverse ways.
一个例子是一部电视剧，其网站上有另类现实游戏，角色拥有社交媒体账号，还有幕后播客。这加强了受众参与，并允许受众以多种方式与文本互动。
10. Audience Measurement Formulas: Ratings, Reach and Share | 受众测量公式：收视率、到达率与份额
In the media industry, audiences are commodified and measured. Understanding the basic formulas for ratings, reach and share enables you to analyse how media organisations evaluate success.
在媒介产业中，受众被商品化并加以测量。理解收视率、到达率和份额的基本公式使你能够分析媒介组织如何评价成功。
Rating (%) = (Number of Target Audience Watching / Total Target Universe) × 100
The rating reflects the percentage of a specific demographic tuned in at a given time. High ratings attract advertisers.
收视率反映特定时间某目标人群收看的百分比。高收视率能吸引广告商。
Reach = Total Number of Different People Exposed to a Message at Least Once
Reach measures the breadth of an audience across a campaign or time period. It is often expressed as a number or percentage of the total population.
到达率衡量在一次活动或时间段内至少接触过一次讯息的不同个体的总数。通常以总数或占总人口的百分比表示。
Share (%) = (Audience for a Channel or Programme / Total Viewing Audience at that Time) × 100
Share indicates the proportion of the actual viewing audience watching a particular channel or programme, revealing competitive performance. Together these formulas quantify the economics of attention.
份额指在实际收看的观众中，观看某一频道或节目的比例，揭示竞争表现。这些公式共同量化了注意力的经济学。
11. Baudrillard’s Hyperreality Theorem | 鲍德里亚超真实定理
Postmodern media theorist Jean Baudrillard argued that in contemporary society, the distinction between reality and its representations has collapsed. His concept of hyperreality can be expressed as a disorientating formula.
后现代媒介理论家让·鲍德里亚认为，在当代社会中，现实与其表征之间的区别已经倒塌。他的超真实概念可以表述为一个令人迷失方向的公式。
Hyperreality = Copy (Simulacrum) Without an Original → More Real than Real
A simulacrum is a copy that no longer refers back to any original reality. For example, a meticulously recreated historical street inside a theme park becomes more ‘real’ in visitors’ experience than the actual historical sites. Media texts such as reality TV or perfect Instagram lives create worlds where the simulation replaces the real.
拟像是一种不再指向任何本原现实的复制品。例如，主题公园内精心重建的历史街区在游客体验中变得比实际历史场所更“真实”。真人秀或完美的Instagram生活等媒介文本创造出拟像取代现实的世界。
This theorem is vital for analysing contemporary media that blend fact and fiction. When a news event becomes a spectacle or a politician’s image is detached from policy, we enter hyperreality. In your analysis, ask: is this text presenting a reflection of reality or creating its own self-referential world?
这个定理对于分析融合事实与虚构的当代媒介至关重要。当新闻事件变成奇观，或政客的形象脱离政策，我们便进入了超真实。在你的分析中，请问：这个文本是在反映现实，还是在创造它自己的自我指涉世界？
12. Feminist Media Theorem: The Male Gaze | 女性主义媒介定理：男性凝视
Laura Mulvey’s concept of the male gaze explains how visual media are structured around a masculine, heterosexual viewer. The male gaze formula reveals power relations encoded into camera work and narrative.
劳拉·穆尔维的男性凝视概念解释了视觉媒介如何以男性异性恋观众为中心进行结构。男性凝视公式揭示了编码在镜头拍摄和叙事中的权力关系。
le Gaze = Woman as Passive Object + Men as Active Bearers of the Look + Camera as Male Eye
In classical Hollywood cinema, the camera positions the audience to view women’s bodies as objects of desire. Female characters are often displayed for male pleasure, their agency reduced to how they appear. Men, by contrast, drive the action and possess the gaze.
在经典好莱坞电影中，摄影机将观众置于将女性身体视为欲望对象的位置。女性角色经常为了男性的愉悦而展演，她们的能动性被简化为其外表。而男性则推动行动并拥有凝视权。
This theorem extends to advertising, music videos and social media. It can be countered by the concept of the ‘female gaze’ or challenging representations that subvert objectification. Use this formula to examine framing: who looks? Who is looked at? Are there moments of disruption?
这一定理延伸至广告、音乐视频和社交媒体。它可以通过“女性凝视”的概念或者颠覆物化的挑战性表征来抗衡。使用这个公式来审视画面构成：谁在看？谁被看？是否存在破坏时刻？
