1. Semiotics Formula: Sign = Signifier + Signified | 符号学公式：符号 = 能指 + 所指
Sign = Signifier + Signified (Barthes)
Roland Barthes broke the sign into two inseparable parts: the signifier is the physical form (a word, image, sound), and the signified is the mental concept it triggers. Their union creates meaning. Barthes also identified a second layer of signification, ‘myth’, where signs carry ideological meanings that appear natural but actually serve dominant interests.
罗兰·巴特将符号分解为不可分割的两部分：能指是物质形式（词语、图像、声音），所指是其引发的心理概念。两者结合创造意义。巴特还识别出第二层意指——’神话’，符号在此层面携带看似自然、实则服务于主流意识形态的意义。
2. Narrative Equilibrium Theorem | 叙事平衡定理
Equilibrium → Disruption → New Equilibrium (Todorov)
Tzvetan Todorov proposed that all narratives follow a three-step structure: an initial state of balance (equilibrium), a disruption by an outside force (disequilibrium), and a resolution that restores order (new equilibrium). This formula can be applied to genres ranging from crime drama to romantic comedy, revealing the predictability beneath seemingly diverse stories.
茨维坦·托多罗夫提出所有叙事都遵循三步结构：初始的平衡状态，被外力打破（失衡），最后通过解决恢复秩序（新平衡）。这一公式适用于从犯罪剧到爱情喜剧的各类叙事，揭示了看似各异的故事背后共同的模式。
3. Binary Opposition Principle | 二元对立原则
Meaning arises from contrast: A vs Not-A (Levi-Strauss)
Claude Levi-Strauss argued that meaning in texts is constructed through binary oppositions, such as good vs evil, hero vs villain, or civilisation vs wilderness. These structural pairs simplify complex ideas and often reinforce cultural value judgements. Analysing how a media product defines and resolves oppositions reveals its underlying ideology.
克劳德·列维-斯特劳斯认为文本的意义通过二元对立建构，如善与恶、英雄与反派、文明与荒野。这些对立结构简化了复杂概念，并常强化文化价值判断。分析媒体产品如何定义与化解对立，可揭示其潜在的意识形态。
4. Character Function Formula | 角色功能公式
Character type × Sphere of action = Narrative function (Propp)
Vladimir Propp studied Russian fairy tales and identified seven recurring character types, each with a fixed narrative function: the Hero, Villain, Donor, Helper, Princess, Dispatcher, and False Hero. Although Propp’s model originates in folklore, it remains applicable to contemporary media, from action films to video games, underscoring the formulaic nature of storytelling.
弗拉基米尔·普罗普研究俄国民间故事，识别出七种反复出现的角色类型，每种有其固定的叙事功能：英雄、反派、赠予者、帮助者、公主、派遣者与假英雄。尽管模型源于民间故事，它仍适用于当代媒体，从动作电影到电子游戏，凸显了叙事的公式化本质。
5. Genre Formula: Repetition + Difference | 类型公式：重复＋差异
Genre = Repetition of conventions + Variation (Neale)
Steve Neale views genre not as a fixed set of rules but as a dynamic process of repetition and difference. Media texts must include enough familiar elements (iconography, narrative patterns) to meet audience expectations, yet offer enough novelty to prevent boredom. This balance explains both genre evolution and hybridisation.
史蒂夫·尼尔将类型视为重复与差异的动态过程，而非固定规则。媒体文本需包含足够熟悉的元素（图像志、叙事模式）以满足受众期待，同时提供足够的新意以避免乏味。这种平衡解释了类型的演变与混合。
6. Hyperreality Equation | 超真实方程
Simulacrum > Reality → Hyperreality (Baudrillard)
Jean Baudrillard argued that in a media-saturated world, representations (simulacra) no longer reflect reality but replace it, creating a ‘hyperreality’ that feels more real than the real. Examples include theme park recreations of historical events or heavily edited social media identities that set unattainable standards.
让·鲍德里亚认为，在媒体饱和的世界中，再现（拟像）不再反映现实，而是取代现实，创造出比真实更真实的’超真实’。例如主题公园中历史事件的重现，或重度编辑的社交媒体身份，设定了难以企及的标准。
7. Representation Theory: Reflective, Intentional, Constructionist | 再现理论：反映、意图与建构主义
Representation = Construction (Hall) → Meaning is made, not found.
Stuart Hall rejected the idea that media simply mirrors reality. He outlined three approaches: the reflective (media reflects pre-existing meaning), the intentional (meaning comes from the author’s intention), and the constructionist, which he favoured. In the constructionist view, meaning is produced through language and codes, shaped by social context. This reminds us that every representation is a choice with ideological implications.
斯图亚特·霍尔否认媒体只是反映现实。他概述了三种路径：反映式（媒体反映既存意义）、意图式（意义源于作者意图）以及他所推崇的建构主义。建构主义认为，意义由语言和符码在社会语境中生产。这提醒我们，每一次再现都是带有意识形态含义的选择。
8. Encoding/Decoding Communication Model | 编码/解码传播模型
Encoding → Message → Decoding: Dominant, Negotiated, Oppositional (Hall)
Stuart Hall’s communication model emphasises that audiences are not passive. Producers encode preferred meanings into texts, but audiences decode them according to their own cultural frameworks. The three decoding positions are: dominant (accepting the preferred meaning), negotiated (partially accepting, partially resisting), and oppositional (rejecting the intended meaning entirely). This framework is vital for analysing audience reception and polysemy.
斯图亚特·霍尔的传播模型强调受众并非被动。生产者将偏好意义编码进文本，但受众依据自身文化框架解码。三种解码立场为：主导式（接受偏好意义）、协商式（部分接受、部分抗拒）和对抗式（完全拒绝原意）。该框架对分析受众接受与多义性至关重要。
9. Social Learning Theory | 社会学习理论
Attention + Retention + Reproduction + Motivation = Imitation (Bandura)
Albert Bandura proposed that individuals learn behaviours by observing media models. The process involves four stages: paying attention to the model, retaining the observed action, being able to reproduce it, and having sufficient motivation (e.g., rewards or punishments shown on screen). This theory is often used in debates about media violence and the influence of role models.
阿尔伯特·班杜拉提出，个体通过观察媒介榜样学习行为。该过程包括四个阶段：注意榜样、记住观察到的行为、有能力再现行为、以及具备充分动机（如屏幕上的奖励或惩罚）。该理论常用于媒体暴力及榜样影响力的讨论。
10. Cultivation Theorem | 涵化定理
Heavy TV viewing → Mainstreaming → Perception of reality (Gerbner)
George Gerbner’s cultivation theorem states that long-term, heavy exposure to television content gradually shapes viewers’ perceptions of social reality. The more time people spend watching TV, the more likely they are to believe the world resembles the TV version—for example, overestimating crime rates or adopting stereotyped gender roles. The effects are particularly pronounced when the media message is consistent and pervasive.
乔治·格伯纳的涵化定理指出，长期大量接触电视内容会逐渐塑造观众对社会现实的认知。观看电视时间越长，人们越可能相信世界与电视版本相似——例如高估犯罪率或接受性别刻板印象。当媒体讯息一致且普遍时，这种效果尤为显著。
11. Media Ownership: Concentration → Homogenisation | 媒体所有权：集中 → 同质化
Ownership concentration → Reduced diversity → Hegemony (Curran and Seaton)
Curran and Seaton argue that media ownership is increasingly concentrated in the hands of a few conglomerates. This limits the range of voices and perspectives, leading to homogenised content that serves corporate and elite interests rather than public service. Their work critiques the free market model, advocating for regulation to preserve pluralism and democratic debate.
柯伦与西顿认为，媒体所有权日益集中在少数集团手中。这限制了声音与视角的范围，导致内容同质化，服务于企业与精英利益而非公共服务。他们的著作批判自由市场模式，主张通过监管维护多元主义与民主讨论。
12. Participatory Culture Formula | 参与式文化公式
Convergence + Collective Intelligence → Participatory Culture (Jenkins)
Henry Jenkins describes participatory culture as a shift from passive consumption to active participation, driven by media convergence and the pooling of collective intelligence. Audiences now create, remix, and share content, blurring the line between producer and consumer. Fan communities, YouTube creators, and social media activism are all expressions of this phenomenon, which challenges traditional top-down media power.
亨利·詹金斯将参与式文化描述为由媒体融合与集体智慧汇聚所驱动的从被动消费向主动参与的转变。受众如今创作、混剪与分享内容，模糊了生产者与消费者的界限。粉丝社区、YouTube创作者与社会媒体行动主义都是这一现象的表现，挑战了传统的自上而下的媒体权力。
