1. Chi-Squared Test Formula | 卡方检验公式

The chi-squared test (χ²) is used to determine whether there is a significant association between two categorical variables in a contingency table. It compares observed frequencies (O) with expected frequencies (E) under the null hypothesis of no association.

卡方检验（χ²）用于判断列联表中两个类别变量之间是否存在显著关联。它比较在无关联原假设下的观察频数（O）与期望频数（E）。

χ² = Σ ( (O − E)² / E )

Calculate the expected frequency for each cell: E = (row total × column total) / grand total.

计算每个单元格的期望频数：E = （行合计 × 列合计）/ 总合计。

The degrees of freedom (df) are given by df = (number of rows − 1) × (number of columns − 1). Compare the calculated χ² against the critical value at p < 0.05.

自由度 df = （行数 − 1）×（列数 − 1）。将计算所得 χ² 值与 p < 0.05 的临界值进行比较。

Step | 步骤	Action | 操作
1	Construct a contingency table and fill in observed counts (O). | 构建列联表，填入观察频数。
2	Compute expected frequencies (E) for each cell. | 计算每个单元格的期望频数。
3	For every cell, calculate (O − E)² / E. | 对每个单元格计算 (O − E)² / E。
4	Sum all the values to obtain χ². | 将所有值求和得到 χ²。
5	Determine df, compare with critical value. | 确定自由度，与临界值比较。

A significant result (χ² > critical value) leads to rejection of the null hypothesis, suggesting a genuine association in the population.

若结果显著（χ² > 临界值），则拒绝原假设，表明总体中存在真实关联。

2. Spearman’s Rank Correlation Coefficient | 斯皮尔曼等级相关系数

Spearman’s rank correlation (rₛ) measures the strength and direction of a monotonic relationship between two ranked variables. It is suitable for ordinal data or when the relationship is not linear.

斯皮尔曼等级相关系数（rₛ）测量两个等级变量之间单调关系的强度与方向。它适用于定序数据或非线性关系。

rₛ = 1 − ( 6 Σ d² ) / [ n (n² − 1) ]

where d = difference between the ranks of each pair of observations, and n = number of pairs. The value of rₛ ranges from −1 (perfect negative correlation) to +1 (perfect positive correlation).

其中 d = 每一对观察值等级之差，n = 数据对数。rₛ 取值从 −1（完全负相关）到 +1（完全正相关）。

Procedure | 步骤	Explanation | 说明
Rank X and Y separately | 分别对 X 和 Y 排序	Assign ranks (1 = highest or lowest) to each variable. | 为每个变量赋予等级（1 为最高或最低）。
Calculate d for each pair | 计算每对数据的 d	d = rank of X − rank of Y. | d = X 等级 − Y 等级。
Square d and sum | 计算 d² 并求和	Compute Σ d². | 求得 Σ d²。
Substitute into formula | 代入公式	Calculate rₛ. | 计算 rₛ。
Test significance | 显著性检验	Compare rₛ with critical value table for Spearman’s n. | 将 rₛ 与对应 n 的临界值表比较。

In sociology, Spearman’s rₛ is often used to test, for instance, whether educational qualification rank correlates with income rank, without assuming a linear pattern.

在社会学中，斯皮尔曼 rₛ 常被用于检验例如学历等级与收入等级之间的相关性，且无需假设线性模式。

3. Durkheim’s Anomie Theorem | 涂尔干的失范定理

Durkheim’s theorem of anomie states that a breakdown of social norms and collective conscience leads to normlessness, which in turn increases the likelihood of deviant behaviour and societal instability. Anomie is most acute during rapid social change when traditional regulations no longer apply.

涂尔干的失范定理指出，社会规范与集体意识的崩溃导致规范缺失，进而增加了越轨行为和社会不稳定的可能性。在传统规范不再适用的急剧社会变革时期，失范最为严重。

He demonstrated this through his analysis of suicide, arguing that anomic suicide rises when society fails to regulate individual aspirations. This ‘theorem’ underpins functionalist explanations of crime and deviance.

他通过分析自杀现象证明了这一点，认为当社会无法约束个人欲望时，失范型自杀便会增多。这一“定理”支撑了功能主义关于犯罪与越轨的解释。

4. Marx’s Law of Base and Superstructure | 马克思的基础与上层建筑法则

Marx proposed that the economic base (forces and relations of production) determines the superstructure — the institutions, ideas, and culture of a society. This is often summarised as the fundamental law of historical materialism: it is not consciousness that determines being, but social being that determines consciousness.

马克思提出，经济基础（生产力与生产关系）决定上层建筑——社会的制度、思想与文化。这常被概括为历史唯物主义的基本法则：不是意识决定存在，而是社会存在决定意识。

Class conflict is the engine of historical change, with each mode of production giving rise to a dominant class and a subordinate class. The capitalist system produces alienation and exploitation, leading toward its own eventual overthrow.

阶级冲突是历史变迁的动力，每一生产方式都产生一个统治阶级和一个被统治阶级。资本主义制度产生异化与剥削，最终导致自身的覆灭。

5. Weber’s Iron Cage of Rationalisation | 韦伯的理性化铁笼定理

Weber’s theorem of rationalisation posits that modern societies become increasingly governed by instrumental rationality, efficiency, and bureaucratic control. This creates an ‘iron cage’ in which individuals are trapped by impersonal rules, diminishing spontaneity and charisma.

韦伯的理性化定理认为，现代社会日益被工具理性、效率和官僚控制所支配。这形成了一个“铁笼”，个体被非人格化的规则所困，自发性和魅力型权威减弱。

Bureaucracy, as the purest form of legal-rational authority, is technically superior but dehumanising. Weber’s law underscores the paradox that rational systems meant to serve humanity can end up enslaving it.

官僚制作为法理型权威的最纯粹形式，技术上优越却非人化。韦伯的定律强调了一个悖论：旨在服务人类的理性系统最终却可能奴役人类。

6. Labelling Theory Theorem (Becker) | 标签理论定理（贝克尔）

Becker’s labelling theorem asserts that deviance is not a quality of the act a person commits, but rather a consequence of the application by others of rules and sanctions to an ‘offender’. The deviant is one to whom that label has been successfully applied.

贝克尔的标签理论定理主张，越轨并非个人行为本身的特性，而是他人将规则与制裁应用于某一“冒犯者”的结果。越轨者就是被成功贴上了标签的人。

The process of labelling can lead to a self-fulfilling prophecy: once an individual is stigmatised, he or she may accept the deviant identity and engage in further deviance. This ‘theorem’ challenges traditional absolutist definitions of crime.

贴标签的过程会导致自我实现预言：个体一旦被污名化，就可能接受越轨身份并进一步实施越轨行为。这一“定理”挑战了传统的绝对主义犯罪定义。

7. Bourdieu’s Cultural Capital Formula | 布迪厄的文化资本公式

Bourdieu conceptualised cultural capital as a symbolic resource that can be converted into educational and economic success. A simple ‘formula’ embodies the idea: (Economic capital + Cultural capital + Social capital) × Habitus = Social position reproduced.

布迪厄将文化资本概念化为可转化为教育成就和经济成功的符号资源。一个简明的“公式”概括了该理念：（经济资本 + 文化资本 + 社会资本）× 惯习 = 社会地位再生产。

Cultural capital exists in three states: embodied (dispositions, accent), objectified (books, art), and institutionalised (qualifications). The education system rewards those who inherit dominant cultural capital, thereby legitimising inequality.

文化资本以三种形态存在：身体化（性情、口音）、客体化（书籍、艺术品）和制度化（学历资格）。教育体系奖励那些继承了主导文化资本的人，从而使不平等合法化。

8. Functionalist Theorem of Value Consensus | 功能主义的价值共识定理

Functionalists, drawing on Durkheim and Parsons, argue that social order is maintained through value consensus — a shared set of norms and values that bond individuals together. The ‘theorem’ states that every institution fulfils necessary functions to ensure social stability.

功能主义者承袭涂尔干和帕森斯的观点，认为社会秩序通过价值共识——套将个体凝聚在一起的共享规范与价值——得以维持。该“定理”指出，每一制度都履行确保社会稳定的必要功能。

Parsons identified four functional prerequisites (AGIL scheme): Adaptation, Goal attainment, Integration, and Latency. Social change is gradual and disruptive deviance is managed through socialisation and social control.

帕森斯提出四种功能前提（AGIL 图式）：适应、目标达成、整合与模式维持。社会变迁是渐进的，而破坏性的越轨则通过社会化与社会控制加以管理。

9. Merton’s Strain Theory Formula | 默顿的紧张理论公式

Merton’s strain theorem proposes that crime and deviance arise from a gap between culturally approved goals and the legitimate means available to achieve them. The ‘formula’ can be expressed as: Anomie = Cultural goals − Institutionalised means.

默顿的紧张定理提出，犯罪与越轨源于文化所肯定的目标与实现这些目标的合法手段之间的鸿沟。该“公式”可表述为：失范 = 文化目标 − 制度化手段。

Individuals adapt in five ways: conformity, innovation, ritualism, retreatism, and rebellion. Innovation — accepting goals but rejecting legitimate means — explains high property crime rates in unequal societies.

个体有五种适应方式：遵从、创新、仪式主义、退却主义和反叛。创新——接受目标却拒绝合法手段——解释了不平等社会中高财产犯罪率。

10. Feminist Patriarchal Structure Theorem | 女性主义父权结构定理

Feminist sociology posits a universal ‘theorem’ that society is structured by patriarchy — a system of male domination that operates through socialisation, economic inequality, and institutional power. Gender is viewed not as natural difference but as a social construct that perpetuates hierarchy.

女性主义社会学提出一条普遍“定理”：社会由父权制——一种通过社会化、经济不平等和制度权力运作的男性支配体系——所构建。性别不被视为自然差异，而被看作巩固等级体系的社会建构。

Liberal feminists seek legal reform, Marxist feminists link patriarchy to capitalism, and radical feminists argue that patriarchy is the primary form of oppression. Intersectionality adds that gender oppression interacts with class and ethnicity.

自由女性主义寻求法律改革，马克思主义女性主义将父权制与资本主义相联系，激进女性主义认为父权制是最根本的压迫形式。交叉性理论补充指出，性别压迫与阶级、族裔相互交织。

11. Cultural Homogenisation vs Hybridity Theorem | 文化同质化与混杂化定理

The globalisation theorem proposes two opposing tendencies: cultural homogenisation (the spread of Western consumer culture leading to sameness) and cultural hybridity (the fusion of cultures creating new, unique forms). The outcome depends on local reception and agency.

全球化定理提出两种相反的趋势：文化同质化（西方消费文化传播导致趋同）和文化混杂化（文化融合创造新的独特形式）。其结果取决于地方的接受和能动性。

Ritzer’s McDonaldization thesis illustrates homogenisation, while Appadurai’s ‘scapes’ and the concept of glocalisation demonstrate hybridity. Both processes are linked to transnational media and migration.

里茨的麦当劳化命题例证了同质化，而阿帕杜莱的“景观”概念以及全球本土化则展示了混杂化。两种过程均与跨国媒体和人口流动相关联。

12. The Correspondence Principle Theorem (Bowles & Gintis) | 对应原则定理（鲍尔斯与金蒂斯）

Bowles and Gintis argued that the school mirrors the workplace, a ‘theorem’ known as the correspondence principle. The hierarchy, obedience, punctuality, and extrinsic rewards in education correspond directly to the demands of capitalist production.

鲍尔斯和金蒂斯认为学校是职场的镜像，这一“定理”被称为对应原则。教育体系中的等级制、服从、准时和外在奖励，与资本主义生产的要求直接对应。

This theorem challenges functionalist claims of meritocracy, revealing that schooling legitimises inequality by masking the reproduction of class relations. The hidden curriculum teaches an acceptance of one’s position in the class structure.

该定理挑战了功能主义的贤能主义声称，揭示出学校通过掩盖阶级关系的再生产而使不平等合法化。隐性课程教导学生接受其在阶级结构中的位置。
