1. Semiotics – The Sign Theorem | 符号学 – 符号定理
The fundamental unit of meaning in media texts is the sign. According to Saussure, a sign comprises the signifier (the physical form) and the signified (the mental concept). The relationship between them is arbitrary and cultural. Barthes expanded this with denotation (literal meaning) and connotation (associated cultural meanings), leading to myth – the ideological naturalisation of connotative meanings.
媒体文本中最基本的意义单位是符号。根据索绪尔，符号由能指（物理形式）和所指（心理概念）构成，二者之间的关系是任意且约定俗成的。巴特在此基础上提出了外延（字面意义）和内涵（联想文化意义），进而形成神话——内涵意义被意识形态化的自然化过程。
- Sign = Signifier + Signified
- Meaning = Denotation + Connotation
- Myth = Connotation presented as natural truth
2. Barthes’ Narrative Codes | 巴特叙事符码
Barthes identified five codes that structure narratives and encourage active reading. The hermeneutic code (enigma) creates suspense by posing questions; the proairetic code (action) builds tension through sequential events; the semantic code refers to connotative meanings; the symbolic code organises deeper thematic oppositions; and the cultural code draws on shared knowledge and ideology.
巴特识别出五种结构叙事并鼓励主动阅读的符码。阐释符码（谜题）通过提问制造悬念；行动符码通过连续事件积累张力；语义符码指向内涵意义；象征符码组织深层的主题对立；文化符码则诉诸共享的知识与意识形态。
Narrative Engagement = Σ (HER + ACT + SEM + SYM + REF)
3. Todorov’s Narrative Equilibrium | 托多罗夫叙事平衡定理
Todorov proposed that conventional narratives follow a five-stage structure: an initial state of equilibrium is disrupted by an event, leading to a recognition of the disruption, an attempt to repair it, and a final new equilibrium. This model applies across film, television drama, news stories and advertising, where a problem is introduced and resolved to reassure audiences.
托多罗夫提出，传统叙事遵循五阶段结构：初始的平衡状态被事件打破，导致对打破的认知、修复尝试，最终达成新的平衡。这一模型适用于电影、电视剧、新闻报道和广告，在其中问题被引入并解决，以安抚观众。
Narrative = Equil. → Disruption → Recognition → Repair → New Equil.
4. Propp’s Character Functions | 普罗普角色函数定理
Vladimir Propp analysed Russian folktales and identified seven recurring character roles (spheres of action): the villain, the donor, the helper, the princess (and her father), the dispatcher, the hero, and the false hero. Each fulfils a narrative function. Modern media texts often subvert or hybridise these types, but the underlying functions remain a powerful analytical tool.
弗拉基米尔·普罗普在分析俄罗斯民间故事后，识别出七种反复出现的角色类型（行动领域）：反派、捐赠者、帮手、公主（及其父王）、派遣者、英雄和假英雄。每种角色履行特定的叙事功能。现代媒体文本经常颠覆或混合这些类型，但其内在功能仍然是强大的分析工具。
| Role 角色 | Function 功能 |
|---|---|
| Villain 反派 | Opposes the hero |
| Donor 捐赠者 | Provides magical object |
| Helper 帮手 | Aids the hero |
| Princess 公主 | Sought-for person/reward |
| Dispatcher 派遣者 | Sends hero on quest |
| Hero 英雄 | Restores equilibrium |
| False Hero 假英雄 | Claims credit falsely |
5. Hall’s Encoding/Decoding Model | 霍尔的编码/解码模型
Stuart Hall argued that media messages are encoded with preferred meanings but audiences decode them based on their own social and cultural contexts. Three reading positions are possible: dominant-hegemonic (accepting the intended meaning), negotiated (partly accepting, partly modifying), and oppositional (rejecting the intended meaning and framing an alternative). The model refutes the idea of passive audiences.
斯图尔特·霍尔指出，媒体信息被编码进偏好意义，但受众根据自己的社会文化语境进行解码。存在三种解码立场：主导-霸权式（接受预期意义）、协商式（部分接受、部分调整）和对抗式（拒绝预期意义并构建替代性意义）。这一模型驳斥了受众被动论。
Decoded Meaning = Message × Audience’s Cultural Framework
6. Uses and Gratifications Theorem | 使用与满足定理
This audience-centred approach posits that media consumption is an active process driven by social and psychological needs. Blumler and Katz identified four main gratifications: personal identity (reinforcing values), surveillance (seeking information), personal relationships (social interaction, parasocial bonds), and diversion (escapism, entertainment). Users actively select media to satisfy these needs.
这一以受众为中心的方法认为，媒体消费是由社会和心理需求驱动的主动过程。布鲁姆勒和卡茨确定了四种主要满足：个人身份（强化价值观）、监视（获取信息）、个人关系（社会互动、准社会关系）和消遣（逃避现实、娱乐）。用户主动选择媒体来满足这些需求。
Media Use = f (Identity + Information + Social Interaction + Entertainment)
7. Representation Theorem | 表征定理
Representation refers to the construction of aspects of reality through media language. David Gauntlett stressed that identities are now more fluid and that media provides resources for identity construction. Richard Dyer examined how stereotypes reduce people to a few exaggerated traits, serving to maintain social boundaries – the ‘typecasting’ equation. Representation = Selection + Mediation + Ideological positioning.
表征是指通过媒体语言对现实的某些方面进行的建构。戴维·冈特莱特强调当代身份更具流动性，媒体为身份建构提供了资源。理查德·戴尔剖析了刻板印象如何将人简化为若干夸张特征，以维持社会边界——“类型化”公式。表征 = 选择 + 中介化 + 意识形态定位。
- Stereotype = Simplified trait + Naturalised + Boundary maintenance
- Mediation = Selection × Framing × Re-presentation
8. Media Language – The Cinematography Equation | 媒体语言 – 摄影方程
Cinematography constructs meaning through the deliberate choice of shot size, camera angle, depth of field, and movement. Close-ups create intimacy or intensity; low angles suggest power; tracking shots imply urgency. Combined with lighting, these elements form a visual syntax. A simple analytical formula links technical choice to connotation and audience effect.
摄影通过刻意选择景别、摄像机角度、景深和运动来建构意义。特写营造亲密感或强度；低角度暗示权力；移动镜头传达紧迫感。这些元素与灯光结合，构成视觉句法。简单的分析公式将技术选择与内涵和受众效果相联系。
Visual Meaning = Shot size × Angle × Lighting × Movement
| Technique 技术 | Possible Connotation 可能内涵 |
|---|---|
| Extreme Close-up | Intensity, emotion |
| Low Angle | Power, authority |
| High Angle | Vulnerability, inferiority |
| High-key Lighting | Optimism, clarity |
| Low-key Lighting | Mystery, danger |
9. The Mise-en-scène Composition Principle | 场面调度构成原理
Mise-en-scène encompasses everything placed in front of the camera: setting, props, costume, hair and makeup, figure expression and movement, and colour. Each element carries symbolic weight. The composition principle states that denotation (literal objects) layers connotations that guide the audience’s interpretation of character, genre and theme. Colour palettes operate as visual codes: red for passion/danger, blue for coldness/calm, etc.
场面调度涵盖置于镜头前的一切：场景、道具、服装、发型和妆容、人物的表情与动作，以及色彩。每个元素都承载象征分量。构成原理表明，外延（实物）叠加了引导观众对角色、类型和主题之解读的内涵。色彩调色板作为视觉符码运作：红色象征激情/危险，蓝色象征冰冷/平静，等等。
Mise-en-scène Meaning = Σ (Setting + Props + Costume + Lighting + Colour)
10. Media Industry – Integration and Power | 媒体产业 – 整合与权力定理
Curran and Seaton argue that media ownership shapes content, limiting diversity in favour of profit and dominant ideology. Vertical integration (controlling production, distribution, consumption) and horizontal integration (owning multiple companies at one stage) reduce risk and maximise synergy. The conglomerate equation links scale to cultural power. The public service broadcasting (PSB) model, championed by the BBC, counters this by prioritising educate, inform and entertain.
库兰和西顿认为，媒体所有权塑造内容，限制多样性以追求利润和主流意识形态。纵向整合（控制生产、发行、消费）和横向整合（在同一阶段拥有多家公司）降低风险并最大化协同效应。集团方程将规模与文化权力挂钩。以BBC为代表的公共服务广播模式则通过优先考虑教育、信息和娱乐来抗衡之。
Media Power = Concentration × Integration × Synergy
11. Cultural Industries Theorem – Hesmondhalgh | 文化产业定理 – 赫斯蒙德哈尔
David Hesmondhalgh identifies the cultural industries as risky businesses that rely on the ‘format’ to minimise uncertainty. Key strategies include: the ‘star system’ to guarantee audiences, genre formatting, serialisation, and cross-media promotion. Copyright is the engine of profit. The theorem highlights a tension between creativity and commerce: cultural production = creativity under corporate control.
戴维·赫斯蒙德哈尔将文化产业界定为高风险行业，它们依赖“格式”来减少不确定性。关键策略包括：用“明星体制”保证受众、类型格式化、系列化以及跨媒体推广。版权是利润的引擎。该定理凸显了创意与商业之间的张力：文化生产 = 公司控制下的创意。
Profit = (Star + Format + Copyright) × Distribution Scale
12. Advertising – The Persuasion Formula | 广告 – 说服公式
Advertising combines emotional and rational appeals to construct a brand identity and stimulate consumption. Gillian Dyer’s lines of appeal (e.g., happy families, elite lifestyles, romantic fantasy) map onto psychological needs. The AIDA model (Attention, Interest, Desire, Action) describes the sequential consumer response. Contemporary advertising also uses personal data to tailor messages, in what Shoshana Zuboff calls ‘surveillance capitalism’.
广告结合情感与理性诉求，构建品牌认同并刺激消费。吉莉安·戴尔的诉求线（如幸福家庭、精英生活方式、浪漫幻想）映射了心理需求。AIDA模型（注意、兴趣、欲望、行动）描述了消费者反应的序列。当代广告还利用个人数据定制讯息，形成肖莎娜·祖博夫所称的“监控资本主义”。
Ad Effectiveness = Emotional appeal × Rational claim × Cultural resonance
- AIDA: Attention → Interest → Desire → Action
