1. Core Propositions of Functionalism | 功能主义核心命题
Society is a system of interconnected parts (institutions) that work together to maintain social order and stability — much like the organs of a living body. This is the organic analogy, central to Durkheim and Parsons.
社会是一个由相互关联的部分（制度）组成的系统，各部分共同运作以维持社会秩序与稳定——很像一个生命体的器官。这就是有机体类比，是涂尔干和帕森斯理论的核心。
Every social institution fulfils a function: manifest (intended, recognised) or latent (unintended, hidden). For example, education transmits knowledge (manifest) and sorts individuals into the labour market (latent).
每个社会制度都发挥某种功能：显性（有意的、被认知的）或隐性（无意的、隐藏的）。例如，教育传递知识（显性功能），并将个体分流进劳动力市场（隐性功能）。
Value consensus — a shared set of norms and values — is the glue that holds society together. Through socialisation, individuals internalise these values, ensuring conformity and social cohesion.
价值共识——一套共享的规范与价值观——是将社会凝聚在一起的粘合剂。通过社会化，个体将这些价值内化，从而确保遵从与社会团结。
Social change is generally gradual and evolutionary; rapid change threatens the equilibrium and leads to anomie (normlessness), a state of moral deregulation that Durkheim linked to higher suicide rates.
社会变迁通常是渐进演化式的；急速的变迁会威胁平衡并导致失范（规范的缺失），涂尔干将这种道德失序状态与较高的自杀率联系起来。
Durational formula: Social integration level ∝ 1/suicide rate. Where social bonds are weak, egoistic suicide rises; where they are excessively strong, altruistic suicide occurs.
涂尔干等式关系：社会整合程度 ∝ 1/自杀率。当社会纽带薄弱时，利己型自杀上升；当纽带过强时，则出现利他型自杀。
2. Core Propositions of Marxism | 马克思主义核心命题
The economic base (infrastructure: means of production + relations of production) shapes the superstructure (family, education, state, religion, media). This is historical materialism: ‘it is not consciousness that determines social being, but social being that determines consciousness.’
经济基础（下层建筑：生产资料 + 生产关系）塑造上层建筑（家庭、教育、国家、宗教、媒体）。这就是历史唯物主义：“不是意识决定社会存在，而是社会存在决定意识。”
Class conflict is the engine of history. In capitalist society, the bourgeoisie (owners of capital) exploit the proletariat (workers) by extracting surplus value — the value produced by workers beyond what is paid in wages.
阶级冲突是历史的动力。在资本主义社会，资产阶级（资本所有者）通过提取剩余价值剥削无产阶级（工人）——剩余价值是工人所创造的价值中超过工资支付的部分。
Ideology operates as a ‘camera obscura’: the ruling class’s ideas become the dominant ideas, masking the true exploitative nature of capitalism. Institutions like the education system transmit a hidden curriculum that legitimates inequality.
意识形态像一台“暗箱”：统治阶级的思想成为占统治地位的思想，掩盖了资本主义真实的剥削本质。像教育系统这类制度传递着使不平等合法化的隐性课程。
Exploitation rate formula: Rate of surplus value = Surplus labour / Necessary labour. This ratio captures the degree of worker exploitation.
剥削率公式：剩余价值率 = 剩余劳动 / 必要劳动。这个比率反映了工人受剥削的程度。
3. Core Propositions of Feminism | 女性主义核心命题
Society is patriarchal — structured by male dominance and female subordination. Gender inequality is not natural but socially constructed through gendered socialisation and institutional practices.
社会是父权制的——由男性支配和女性从属所构建。性别不平等并非自然形成，而是通过性别社会化与制度实践被社会地建构出来。
Liberal feminists seek legal and policy reforms to remove barriers to women’s advancement; Marxist/socialist feminists tie women’s oppression to capitalism, which benefits from unpaid domestic labour; radical feminists argue that patriarchy is the primary form of oppression, rooted in the control of women’s bodies and sexuality.
自由派女性主义寻求通过法律和政策改革消除妇女晋升的障碍；马克思主义/社会主义女性主义将妇女压迫与资本主义联系起来，后者从无偿家务劳动中获益；激进女性主义认为父权制是首要的压迫形式，根植于对女性身体与性行为的控制。
Walby’s six structures of patriarchy: Paid work, household production, culture, sexuality, male violence, and the state. These interconnected structures maintain gender inequality.
沃尔比的六大父权结构：有酬工作、家务生产、文化、性、男性暴力以及国家。这些相互关联的结构维持着性别不平等。
4. Core Propositions of Social Action Theories | 社会行动理论核心命题
Unlike structural theories, social action approaches place the individual at the centre: society is the product of human interaction and meaning-making. Weber’s verstehen requires understanding the subjective meanings actors attach to their actions.
与结构理论不同，社会行动取向将个体置于中心：社会是人类互动与意义建构的产物。韦伯的“理解”要求把握行动者赋予其行动的主观意义。
Weber’s four types of action: Instrumental-rational (means-end calculation), value-rational (commitment to a value), affective (emotional), and traditional (habit). These ideal types help analyse social behaviour.
韦伯的四种行动类型：工具理性（手段-目的计算）、价值理性（对某种价值的信奉）、情感式（情绪驱动）和传统式（习惯）。这些理想类型有助于分析社会行为。
Symbolic interactionism (Mead, Blumer) argues that meaning arises through symbols in interaction; the self is formed through the ‘looking-glass self’ (Cooley) and role-taking (Mead). Labelling theory shows how societal reactions can amplify deviance (Lemert, Becker).
符号互动论（米德、布鲁默）认为，意义通过互动中的符号生成；自我通过“镜中我”（库利）与角色扮演（米德）形成。标签理论表明社会反应如何放大偏差行为（莱默特、贝克）。
5. Research Methods: Key Principles | 研究方法：关键原则
Reliability means consistency: if a study is repeated under the same conditions, it yields the same results. It is usually high in quantitative methods (e.g. structured questionnaires).
信度指一致性：一项研究若在相同条件下重复进行，会得出相同结果。它在定量方法（如结构化问卷）中通常较高。
Validity means truthfulness: does the research measure what it claims to measure? Qualitative methods (e.g. in-depth interviews) often achieve higher validity by capturing lived experiences.
效度指真实性：研究是否测量了它声称要测量的东西？定性方法（如深度访谈）往往因能捕捉生活经验而获得更高的效度。
Representativeness asks: can the findings be generalised from the sample to the wider population? Large-scale random sampling improves representativeness; small purposive samples rarely do.
代表性问的是：研究结果能否从样本推广到更广泛的总体？大规模随机抽样能提高代表性；小额目的性抽样则很少能做到。
Ethics: Researchers must obtain informed consent, ensure confidentiality, avoid harm, and respect the right to withdraw. Covert observation raises serious ethical dilemmas.
伦理：研究者必须获得知情同意，确保保密，避免伤害，并尊重退出权。隐蔽观察会引发严重的伦理困境。
6. Sampling: Key Formulae and Concepts | 抽样：关键公式与概念
Sampling frame is a list of all members of the target population. The quality of the frame directly affects representativeness.
抽样框是目标总体中所有成员的名录。其质量直接影响代表性。
Simple random sampling gives each member an equal chance: probability of selection = sample size / population size. For a population of N=1000 and sample n=100, the probability is 0.1.
简单随机抽样给予每个成员均等机会：被选中的概率 = 样本量 / 总体量。若总体 N=1000，样本 n=100，则概率为 0.1。
Stratified sampling divides the population into strata (e.g. class, gender) and selects randomly from each. Stratum sample size = (stratum proportion × total sample). This ensures key groups are represented.
分层抽样将总体分成不同层（如阶级、性别），然后从每层中随机抽取。层样本量 =（层比例 × 总样本量）。这确保了关键群体被代表。
Sampling error is the difference between the sample statistic and the true population parameter. It can be estimated with the standard error formula: SE = σ / √n, where σ is the population standard deviation. Larger samples reduce sampling error.
抽样误差是样本统计量与总体参数真值之间的差异。可用标准误公式估计：SE = σ / √n，其中 σ 为总体标准差。样本越大，抽样误差越小。
7. Quantitative Data Analysis: Quick Reference | 定量数据分析：速查参考
Measures of central tendency:
- Mean: x̄ = Σx / n
- Median: middle value when data are ordered
- Mode: most frequent value
集中趋势测量：
- 平均数：x̄ = Σx / n
- 中位数：数据排序后的中间值
- 众数：出现频率最高的值
Measures of dispersion: Range = max – min; Interquartile range = Q₃ – Q₁. Variance = Σ(x – x̄)² / n; Standard deviation = √variance. A larger standard deviation indicates greater spread.
离散度测量：全距 = 最大值 – 最小值；四分位距 = Q₃ – Q₁。方差 = Σ(x – x̄)² / n；标准差 = √方差。标准差越大，离散程度越高。
Cross-tabulations (contingency tables) present the joint frequency distribution of two variables. Sociologists use them to spot patterns, e.g. between class and educational achievement.
交叉表（列联表）呈现两个变量的联合频数分布。社会学家用以探查模式，例如阶级与教育成就之间的关联。
Correlation (not causation) can be indicated by a correlation coefficient r ranging from –1 to +1. A positive r means as one variable increases, so does the other; negative r means inverse relationship. Note: correlation ≠ causation.
相关（非因果）可用相关系数 r 表示，范围从 –1 到 +1。正 r 意味着一变量增加，另一变量也增加；负 r 表示反向关系。注意：相关 ≠ 因果。
8. Qualitative Methods: Key Concepts | 定性研究方法：关键概念
Interpretivism favours qualitative methods to uncover meanings and motives. Methods include unstructured interviews, participant observation, and personal documents.
解释主义偏好定性方法以揭示意义与动机。方法包括非结构化访谈、参与式观察及个人文献。
Triangulation is the use of multiple methods or data sources to cross-check findings, increasing validity and depth. Denzin identified four types: data, investigator, theory, and methodological triangulation.
三角验证是运用多种方法或数据来源交叉检验研究结果，以提高效度与深度。丹钦划分了四种类型：数据三角、研究者三角、理论三角和方法三角。
Reflexivity requires researchers to reflect on their own biases, values, and impact on the research process. It is a cornerstone of feminist and postmodern approaches.
自反性要求研究者反思自身的偏见、价值观及其对研究过程的影响。它是女性主义与后现代取向的基石。
Grounded theory (Glaser and Strauss) builds theory inductively from data, through constant comparison, rather than testing pre-existing hypotheses. Coding moves from open to axial to selective.
扎根理论（格拉泽与施特劳斯）通过持续比较法，从数据中归纳建构理论，而非检验预设假设。编码从开放式到轴心式再到选择性。
9. Social Stratification: Key Theorems | 社会分层：关键定理
Davis and Moore’s functionalist theory of stratification: social inequality is functionally necessary. The most important positions must be filled by the most talented persons, and higher rewards motivate individuals to undergo long training and sacrifice.
戴维斯与莫尔的分层功能论：社会不平等是功能上必要的。最重要的职位必须由最有才能的人担任，更高的报酬激励个体接受长期训练与牺牲。
Bourdieu’s forms of capital: Economic capital (wealth), cultural capital (knowledge, tastes, credentials), and social capital (networks). The education system converts cultural capital into academic success, reproducing class advantage.
布迪厄的资本形式：经济资本（财富）、文化资本（知识、品味、文凭）和社会资本（关系网络）。教育系统将文化资本转化为学业成功，从而再生产阶级优势。
Weber’s multi-dimensional model: Stratification has three dimensions — class (economic position), status (social honour), and party (political power). Unlike Marx, Weber argued that status and party can operate independently of class.
韦伯的多维模型：分层有三个维度——阶级（经济地位）、地位（社会荣誉）与政党（政治权力）。与马克思不同，韦伯认为地位与政党可以独立于阶级运作。
Absolute vs relative poverty: Absolute poverty is a fixed threshold (e.g. $1.90 a day); relative poverty is defined as household income below 60% of median income. Townsend’s relative deprivation index combines multiple indicators.
绝对贫困 vs 相对贫困：绝对贫困是一个固定门槛（如每日1.90美元）；相对贫困定义为家庭收入低于中位收入的60%。汤森的剥夺指数综合了多种指标。
10. Crime and Deviance: Key Theorems | 犯罪与偏差：关键定理
Durkheim’s positive functions of crime: Crime is normal and necessary — it clarifies moral boundaries (punishment reaffirms shared values) and can promote social change (e.g. civil rights movements). Too much crime signals anomie.
涂尔干的犯罪正功能：犯罪是正常且必要的——它澄清道德边界（惩罚重申了共享价值），并能推动社会变迁（如民权运动）。过多的犯罪则意味着失范。
Merton’s strain theory: The disjunction between culturally approved goals (wealth) and legitimate means creates strain. Individuals adapt through conformity, innovation, ritualism, retreatism, or rebellion.
默顿的紧张理论：文化认可的目标（财富）与合法手段之间的脱节产生紧张。个体以遵从、创新、仪式主义、退却或反叛等方式适应。
Becker’s labelling theory: Deviance is not a quality of the act, but a consequence of the application of rules by others. A ‘deviant’ is someone to whom the label has been successfully applied; secondary deviance occurs when the labelled person internalises this identity.
贝克尔的标签理论：偏差并非行为本身的特质，而是他人运用规则的结果。“偏差者”是那些被成功贴上标签的人；当被贴标签者将这一身份内化时，便产生继发性偏差。
Cohen’s status frustration: Working-class boys, unable to achieve status in the middle-class school system, experience status frustration and form delinquent subcultures that invert mainstream values.
科恩的地位挫折：工人阶级男生无法在中产阶级的学校体系中获得地位，于是经历地位挫折，形成颠覆主流价值的偏差亚文化。
Right realism: Focuses on rational choice theory — crime occurs when perceived benefits outweigh perceived costs. Wilson and Kelling’s ‘broken windows’ thesis argues that visible signs of disorder invite more serious crime.
右翼现实主义：聚焦理性选择理论——当犯罪感知到的收益超过感知成本时，犯罪发生。威尔逊与凯林的“破窗效应”认为，可见的无序迹象会引来更严重的犯罪。
11. Education: Core Propositions | 教育社会学核心命题
Bowles and Gintis’ correspondence principle: The structure of schooling mirrors the structure of capitalist production. Schools reproduce a docile, compliant workforce through hierarchical relations, discipline, and the hidden curriculum.
鲍尔斯与金蒂斯的一致性原理：学校教育的结构反映了资本主义生产的结构。通过等级关系、纪律和隐性课程，学校再生产了一支温顺服从的劳动力。
Bernstein’s language codes: Working-class children tend to use a restricted code (context-dependent, implicit), while middle-class children possess an elaborated code (universalistic, explicit). The elaborated code is rewarded in education, giving middle-class students a built-in advantage.
伯恩斯坦的语言符码：工人阶级子女倾向于使用受限符码（依赖语境、含蓄），而中产阶级子女掌握精密型符码（普遍性、明确）。后者在学校教育中获得奖赏，使中产阶级学生拥有内在优势。
Material and cultural deprivation: Working-class underachievement is explained by lack of material resources (poor housing, low income) and cultural deprivation (lack of books, parental attitudes). Compensatory education policies, such as Sure Start, aim to bridge the gap.
物质与文化剥夺：工人阶级学业不良可由物质资源匮乏（住房差、收入低）及文化剥夺（缺少书籍、家长态度）来解释。补偿性教育政策（如 Sure Start 计划）旨在缩小差距。
Pupil subcultures — pro-school vs anti-school — shape achievement. Lacey’s concepts of differentiation and polarisation explain how streaming creates these opposing subcultures.
学生亚文化——亲学校与反学校——形塑学业成就。莱西的分化与两极化概念解释了分轨制如何催生这些对立亚文化。
12. Belief Systems: Key Theorems | 宗教与社会信仰定理
Durkheim’s elementary forms: Religion is society worshipping itself. The sacred and the profane are distinguished through rituals (collective effervescence) that bind individuals together, reinforcing social integration.
涂尔干的宗教基本形式：宗教是社会在崇拜自身。神圣与世俗通过仪式（集体欢腾）被区分开来，这些仪式将个体联结在一起，强化社会整合。
Marx’s ‘opium of the people’: Religion legitimates class inequality by promising heavenly rewards for earthly suffering, thus dulling the pain of exploitation and preventing revolutionary consciousness.
马克思的“人民的鸦片”：宗教通过允诺天堂的回报以换取现世的苦难，使阶级不平等合法化，从而麻痹剥削之痛并阻碍革命意识。
Weber’s Protestant ethic thesis: The Calvinist belief in predestination generated a ‘salvation anxiety’, which was relieved by worldly asceticism — hard work, thrift, and profit-seeking. This unintentionally contributed to the rise of modern capitalism.
韦伯的新教伦理命题：加尔文宗的预定论信仰产生了“救赎焦虑”，这通过世俗禁欲主义得以缓解——勤奋工作、节俭及逐利。这在无意中促成了现代资本主义的兴起。
Secularisation debate: Wilson argues that religious beliefs, practices, and institutions have lost social significance — measured via church attendance, membership, and influence. However, Davie’s ‘believing without belonging’ and Hervieu-Léger’s ‘cultural amnesia’ offer nuanced counterpoints.
世俗化辩论：威尔逊认为，宗教信仰、实践和制度已失去社会重要性——通过教会出席率、会员人数和影响力来衡量。然而，戴维的“信而不属”与埃尔维优-莱杰的“文化失忆”提供了微妙的反对观点。
