📚 AS CIE Media Studies: Formula & Theorem Quick Reference Handbook | AS CIE 媒体研究：公式定理速查手册
This quick reference handbook distils key AS Media Studies theories into memorable ‘formulas’ and ‘theorems’. While media theory is not mathematical, these simplified models help you recall the essential components of media language, representation, audience and institution for the CIE AS examination.
这本速查手册将AS媒体研究的关键理论提炼为易记的‘公式’和‘定理’。虽然媒体理论并非数学公式，但这些简化模型可以帮助你在CIE AS考试中回忆媒体语言、表征、受众和制度的基本组成部分。
1. Semiotics Formula: Sign = Signifier + Signified | 符号学公式：符号 = 能指 + 所指
Sign = Signifier + Signified
Ferdinand de Saussure’s foundational concept: every sign consists of a signifier (the sound, image, or word) and a signified (the concept it represents).
费迪南·德·索绪尔的基本概念：每个符号都由能指（声音、图像或词语）和所指（它所代表的概念）组成。
Barthes added layers of denotation (literal meaning) and connotation (cultural associations), but the core equation remains constant.
巴特增加了外延（字面意义）和内涵（文化联想）层次，但核心等式保持不变。
2. Narrative Equilibrium Theorem (Todorov) | 叙事平衡定理（托多罗夫）
Equilibrium → Disruption → Recognition → Attempt to Repair → New Equilibrium
Todorov proposed that all narratives follow this five-stage structure. It begins with a state of equilibrium, which is then disrupted by an event.
托多罗夫提出所有叙事都遵循这五个阶段的结构。从平衡状态开始，随后被某个事件打破。
The disruption is recognised, leading to an attempt to repair the damage, before a new equilibrium is established, often changed from the original.
打破被识别后，试图修复损害，最终建立一个新的平衡，通常与起初不同。
3. Character Function Theorem (Propp) | 角色功能定理（普罗普）
Narrative = Σ (Character Functions) across 7 Spheres of Action
Vladimir Propp analysed Russian folk tales and identified 31 narrative functions and 7 broad character types (spheres of action): Villain, Hero, Donor, Helper, Princess, Dispatcher, False Hero.
弗拉基米尔·普罗普分析了俄罗斯民间故事，确定了31种叙事功能和7种宽泛的角色类型（行动圈）：反派、英雄、捐献者、帮手、公主、派遣者、假英雄。
These functions and characters combine like variables in an equation to generate the story.
这些功能和角色像方程中的变量一样组合生成故事。
4. Binary Opposition Theorem (Levi-Strauss) | 二元对立定理（列维-斯特劳斯）
Meaning = Conflict between Binary Oppositions (e.g. Good ↔ Evil)
Claude Levi-Strauss argued that narratives are structured around pairs of opposing concepts, such as hero/villain, light/dark, or civilisation/wilderness. The resolution of these conflicts creates meaning.
克劳德·列维-斯特劳斯认为，叙事围绕成对的对立概念构建，例如英雄/反派、光明/黑暗或文明/荒野。这些冲突的解决创造了意义。
In media, binary oppositions simplify complex issues and reinforce dominant ideologies.
在媒体中，二元对立简化了复杂问题并强化了主流意识形态。
5. Genre Formula: Iconography + Structure + Theme | 类型公式：图像志 + 结构 + 主题
Genre = Iconography + Narrative Structure + Recurring Themes
Genre is a combination of visual and auditory codes (iconography), predictable story patterns (structure), and underlying ideas or messages (themes). For example, a Western genre uses cowboy hats, saloons, frontier justice, and themes of civilisation versus savagery.
类型是视觉和听觉符码（图像志）、可预测的故事模式（结构）以及潜在观念或信息（主题）的组合。例如，西部类型使用牛仔帽、酒馆、边疆正义以及文明与野蛮的主题。
Steve Neale stressed that genre is also about repetition and difference to keep audiences engaged.
史蒂夫·尼尔强调，类型还关乎重复与差异，以保持观众的参与。
6. Uses and Gratifications Formula | 使用与满足公式
Media Use = Surveillance + Personal Identity + Personal Relationships + Diversion
Blumler and McQuail’s model sees audiences as active: they use media to fulfil needs. These needs include information and understanding (surveillance), reinforcing self-image (personal identity), social interaction (personal relationships), and escapism (diversion).
布卢姆勒与麦奎尔的模型将受众视为主动者：他们使用媒体来满足需求。这些需求包括信息和理解（监视）、强化自我形象（个人身份）、社交互动（人际关系）以及逃避现实（消遣）。
The formula helps evaluate why different audiences choose specific media texts.
该公式有助于评估不同受众为何选择特定的媒体文本。
7. Encoding/Decoding Theorem (Hall) | 编码/解码定理（霍尔）
Meaning = Dominant, Negotiated, or Oppositional Reading
Stuart Hall’s model: producers encode a preferred meaning into a text, but audiences decode it based on their cultural background. The result can be a dominant-hegemonic reading (accepting the intended meaning), a negotiated reading (partially accepting and adapting), or an oppositional reading (rejecting the intended meaning).
斯图尔特·霍尔的模型：生产者将偏好意义编码进文本，但受众根据自己的文化背景进行解码。结果可以是主导-霸权式解读（接受意图意义）、协商式解读（部分接受并调整）或对抗式解读（拒绝意图意义）。
This theorem explains why the same media text can be understood differently.
该定理解释了为何同一媒体文本可以被不同理解。
8. Representation Theorem: Selection + Construction + Mediation | 表征定理：选择 + 建构 + 中介
Representation = Selection + Construction + Mediation
Media representations are not reality but constructed through selective inclusion/exclusion of details, active construction using technical and symbolic codes, and mediation by institutional and ideological contexts. Stuart Hall and others emphasise that representation involves power: who is represented, how, and to what end.
媒体表征并非现实，而是通过选择性包含/排除细节、使用技术和象征符码的主动建构，以及制度和意识形态背景的中介构建而成。霍尔等人强调，表征涉及权力：谁被表征、如何表征、为了什么目的。
This theorem reminds us to question the ‘naturalness’ of media images.
该定理提醒我们质疑媒体形象的‘自然性’。
9. News Values Formula (Galtung & Ruge) | 新闻价值公式（加尔通与鲁格）
News Worthiness = Threshold + Frequency + Negativity + Unexpectedness + Personalisation + Elite Reference + etc.
Galtung and Ruge identified a set of news values that determine whether an event becomes ‘news’. Key factors include threshold (magnitude), frequency (fit with news cycle), negativity, unexpectedness, personalisation (human interest), and reference to elite persons or nations.
加尔通和鲁格确定了一套决定一个事件是否成为‘新闻’的新闻价值因素。关键因素包括门槛（规模）、频率（与新闻周期的契合度）、负面性、意外性、个性化（人情味）以及涉及精英人物或国家。
Editors and journalists apply this formula to filter and prioritise stories.
编辑和记者运用这个公式来过滤和排序新闻。
10. Media Ownership Theorem: Pluralism vs. Marxism | 媒体所有权定理：多元论与马克思主义
If Ownership = Diverse & Market-Driven → Content = Pluralist Views
If Ownership = Concentrated (Elite) → Content = Dominant Ideology
Pluralists argue that a free market of media owners results in a diverse range of content because owners compete for audiences. Marxist theorists, such as Curran and Seaton, contend that concentrated ownership (e.g. conglomerates) leads to content that serves elite interests and reinforces capitalist ideology.
多元论者认为，自由的媒体所有者市场会带来多样的内容，因为所有者竞争受众。马克思主义理论家，如柯伦和西顿，认为集中的所有权（如大型集团）会导致内容服务于精英利益并强化资本主义意识形态。
This theorem is a quick tool for analysing the relationship between media ownership and output.
该定理是分析媒体所有权与输出之间关系的快捷工具。
