Abstract

This chapter addresses the foundational challenge of quantitative social science: transforming abstract theoretical concepts into empirically tractable research questions and valid measurements. We examine the systematic process through which researchers move from conceptualization to operationalization, understanding this progression as iterative rather than linear. The chapter is organized into five main sections: (1) conceptualization and construct formation, distinguishing everyday concepts from scientific constructs and addressing issues of conceptual clarity and multidimensionality; (2) research question discovery, examining sources of questions and criteria for evaluating their importance, answerability, and theoretical grounding; (3) formal definition of research questions, demonstrating how natural language questions are translated into precise statements specifying constructs, populations, interventions, outcomes, and estimands; (4) operationalization, analyzing the concept-indicator relationship, measurement strategy selection, and construct validity; and (5) measurement theory, introducing classical test theory, reliability and validity assessment, levels of measurement, and the structure and consequences of measurement error. Throughout, we maintain awareness that operationalization produces operational social facts—partial, convention-laden representations selected for analytical tractability—while arguing that this methodological strategy remains indispensable for systematic empirical investigation. The chapter emphasizes that measurement choices fundamentally shape what research designs are possible and what inferences they can support, making operationalization not a preliminary technical matter but a substantive process integral to research design.

Abstract

This paper proposes a systematic framework for analyzing research designs, conceptualizing quantitative social science research designs as specific configurations across a finite set of design dimensions. Design dimensions describe the fundamental nature of a study, distinct from specific statistical methods or data collection techniques. By identifying ten core dimensions, including intervention structure, assignment mechanism, temporal structure, unit tracking, directionality of inquiry, comparison logic, data provenance, sampling strategy, unit of analysis, and confounding control strategy. This framework attempts to describe research designs and reveal the essence of canonical research schemes (such as randomized controlled trials, cohort studies, regression discontinuity designs, etc.) as particular dimensional configurations. This framework is expected to help researchers understand the underlying logic of existing designs and guide design choices and innovations under practical constraints.

1. Introduction: From Research Schemes to Design Dimensions

1.1 Problem Statement

In quantitative social science research, the choice of research design directly determines what questions can be answered, what inferences are supported, and what validity threats are faced. Traditional research methods teaching typically introduces specific research schemes directly—randomized controlled trials (RCTs), quasi-experimental designs, cohort studies, cross-sectional studies, etc.—but rarely systematically articulates the common structure underlying these schemes.

Document Context and Reading Background

Document Title: “First Draft Code of Practice on Transparency of AI-Generated Content” / “《AI 生成内容透明度实践准则（草案）》”[1]

Year: December 2025

Overview: The document “First Draft Code of Practice on Transparency of AI-Generated Content” serves as one of the implementing documents accompanying Article 50 of the EU’s Artificial Intelligence Act (AI Act). This first draft of the Code of Practice on Transparency of AI-Generated Content was jointly drafted by two working groups targeting different regulatory subjects:

First, Working Group 1 (WG1) focuses on technical marking and detection of AI-generated content, corresponding to Articles 50(2) and 50(5).

Second, Working Group 2 (WG2) focuses on disclosure, labeling, and perceptible transparency for natural persons, corresponding to Articles 50(4) and 50(5).

This document does not possess direct legislative force. Its primary function is to transform the highly abstract transparency obligations in the AI Act into operable technical and organizational measures, and to provide practical reference for market surveillance authorities in assessing compliance. Adherence to this code does not automatically constitute compliance, but holds significant reference value in compliance demonstration.

Introduction: Ontological and Epistemological Foundations of Research Questions

The effectiveness of quantitative social science research depends on the precision and testability of research questions. However, the most common methodological deficiency in empirical research stems not from technical errors in statistical inference, but from conceptual ambiguity and operational unmeasurability at the question level itself.

A research question that appears clear at the natural language level often reveals numerous implicit ontological commitments, untested causal assumptions, and unclear measurement models when entering the operationalization stage of empirical research.

This paper aims to systematically articulate the front-end epistemic work in research design: how to transform a phenomenological observation into an operable, measurable, and testable scientific question. This process includes four core components: question discovery, conceptual clarification, theoretical positioning, and operationalization modeling.

Title: 親の小児期逆境体験が次世代の精神病理に与える影響に関する研究の現状と課題
(Intergenerational Effect of Parental Adverse Childhood Experiences on the Next Generation’s Psychopathology: A Literature Review)

Journal: The Japanese Journal of Developmental Psychology, Vol.33, No.2

II. Key Terms

2.1 ACEs (Adverse Childhood Experiences)

ACEs refer to adverse experiences encountered during ages 0-18. This concept was first introduced by Felitti et al. in 1998, encompassing two major categories:

(1) Abuse Experiences

• Psychological abuse
• Sexual abuse
• Physical abuse
• Physical neglect
• Emotional neglect

(2) Household Dysfunction

• Mental illness in household members
• Domestic violence (father to mother)
• Substance abuse by household members
• Incarceration of household members
• Parental separation or divorce

It should be noted that the definition of ACEs remains debated in academia. Some researchers argue that adversities experienced outside the home (such as bullying victimization, community violence) should also be included in ACEs, though Felitti et al.’s original definition primarily focused on adversities within the household.

2.2 Internalizing Problems

Internalizing problems refer to psychological and behavioral issues where individuals direct their psychological distress inward, primarily manifesting as emotional and affective difficulties. Typical internalizing problems include:

• Depression: Persistent low mood, loss of interest, diminished self-worth
• Anxiety: Excessive worry, fear, avoidance behavior
• Withdrawal behavior: Social withdrawal, avoidance of interpersonal interactions
• Somatic complaints: Physical discomfort without clear medical cause

Internalizing problems are often difficult for others to observe; children may appear quiet and compliant, making these issues easy to overlook. If not addressed promptly, such problems may develop into clinical-level mood disorders.

2.3 Externalizing Problems

Externalizing problems refer to instances where individuals express psychological distress through overt behaviors, manifesting as destructive or impulsive actions toward the external environment. Typical externalizing problems include:

• Aggression: Physical aggression, verbal aggression, property destruction
• Rule-breaking behavior: Violating rules, lying, stealing
• Hyperactivity-impulsivity: Inattention, restlessness, impulsive behavior
• Oppositional defiant behavior: Deliberate defiance, irritability, vindictiveness

Externalizing problems are relatively easy to observe because these behaviors directly impact others and the environment, often attracting the attention of parents and teachers more readily.

2. 重要术语 | Key Terms

2.1 近红外线光谱法 | Near-Infrared Spectroscopy (NIRS)

中文：

近红外线光谱法是一种利用近红外光进行脑功能测量的方法。

该方法通过测量大脑皮质中氧合血红蛋白与脱氧血红蛋白浓度相对于基线的变化，来反映脑功能活动状态。

其主要特点在于（1）能够在自然姿势下进行测量，（2）方法简便且非侵袭性，对受试者的身体负担较小，因此适合在临床现场反复实施。

其却显示该方法只能测量大脑皮质的功能活动，无法获取深部脑结构的信息；在时间分辨率方面较高，但空间分辨率相对有限。

English:

Near-infrared spectroscopy (NIRS) is a method for measuring brain function using near-infrared light.

This method reflects brain functional activity by measuring changes in oxygenated and deoxygenated hemoglobin concentrations in the cerebral cortex relative to baseline.

Its main characteristics include: (1) the ability to conduct measurements in natural postures, and (2) simplicity and non-invasiveness with minimal physical burden on subjects, making it suitable for repeated implementation in clinical settings.

However, this method can only measure functional activity in the cerebral cortex and cannot obtain information from deep brain structures; it has high temporal resolution but relatively limited spatial resolution.

美妆的双重功能 | The Dual Function of Makeup

中文：

在基于精神分析的学说下,美妆呈现出两种看似矛盾却又相互关联的功能。第一种功能是结构化人的身体,使身体成为构筑社会差异的场所。通过特定的妆容风格、品牌选择和技法运用,身体被纳入符号网络,成为可被解读的文本。这是拉康意义上的大他者通过身体说话,阶级品味、性别规范、文化归属都在妆面上显影。在这个维度中,欲望是社会性的,是他者的欲望。

第二种功能则指向了符号秩序无法完全收编的实在。例如，卧蚕强调的缺失、眼影制造的凝视的异质性、口红勾勒的裂缝,这些都在光滑的象征表面制造创伤性的标记。它们提醒我们,身体不仅是文化建构,也是欲望无法被驯服的场所,是享乐溢出之处。这种双重性或许正是美妆的迷人之处,它既是规训的工具,又是对规训的僭越,既掩盖缺乏,又通过刻意标记使缺乏显现。从这个角度看,化妆既不是纯粹的压迫也不是纯粹的解放,而是主体在象征界与实在界之间的协商。

English:

Under psychoanalytic theory, makeup presents two seemingly contradictory yet interconnected functions. The first function is to structure the human body, making it a site for constructing social differences. Through specific makeup styles, brand choices, and technical applications, the body is incorporated into a network of signs, becoming a readable text. This is the Lacanian Big Other speaking through the body—class taste, gender norms, and cultural belonging all manifest on the made-up face. In this dimension, desire is social; it is the desire of the Other.

The second function points toward the Real that cannot be fully assimilated by the symbolic order. For example, the emphasized absence of aegyo-sal (eye bags), the heterogeneity of the gaze created by eyeshadow, and the fissures outlined by lipstick all create traumatic marks on the smooth symbolic surface. They remind us that the body is not merely a cultural construction but also a site where desire cannot be tamed, where jouissance overflows. This duality may be precisely what makes makeup fascinating: it is both a tool of discipline and a transgression of discipline, both concealing lack and making lack visible through deliberate marking. From this perspective, makeup is neither pure oppression nor pure liberation, but rather a negotiation by the subject between the Symbolic and the Real.

缺失的中介：拉康理论中的女性位置与主体结构

The Mediation of Lack: Feminine Position and Subject Structure in Lacanian Theory

说明

Note

本文是对雅克·拉康（Jacques Lacan）精神分析理论的学术阐释，聚焦于其关于符号秩序、主体生成与欲望结构的理论建构。文中使用的”女性位置””男性位置””癔症结构”等概念，均为拉康理论体系内的专业术语，指涉的是符号系统中的结构性位置，这些概念超越了生理性别、社会性别、人格类型或任何关于现实个体的经验性判断。

This article is an academic exposition of Jacques Lacan’s psychoanalytic theory, focusing on his theoretical construction of the symbolic order, subject formation, and the structure of desire. The concepts used in this text such as “feminine position,” “masculine position,” and “hysteric structure” are all technical terms within Lacan’s theoretical system, referring to structural positions within the symbolic system. These concepts transcend biological sex, social gender, personality types, or any empirical judgments about actual individuals.

“女性位置”（position féminine）在拉康理论中指的是：在以某个核心能指为中心组织的符号秩序中，无法被完全纳入”有/无”二元逻辑的结构性位置。这个位置可以被任何性别的主体占据，其核心特征是与符号秩序的”非全”关系。同样，”男性位置”指的是能够在符号秩序中通过该核心能指获得稳定定位的结构性位置。

The “feminine position” (position féminine) in Lacanian theory refers to a structural position within the symbolic order (organized around a core signifier) that cannot be fully inscribed into the binary logic of “having/lacking.” This position can be occupied by subjects of any gender, and its core characteristic is a relation of “not-all” (pas-toute) to the symbolic order. Similarly, the “masculine position” refers to a structural position that can achieve stable positioning within the symbolic order through that core signifier.

本文讨论的是精神分析与主体生成理论中的结构性问题，所使用的”女性””男性””癔症”等概念，均指向符号秩序与主体位置中的结构角色。

This article discusses structural problems in psychoanalysis and theories of subject formation. The use of terms such as “feminine,” “masculine,” and “hysteria” all point to structural roles within the symbolic order and subject positions.

本讨论不旨在对任何性别或群体作出规范性评价，而是尝试理解：在特定社会与符号条件下，主体如何以不同方式被生成、被分配、并维持其稳定性。

This discussion does not aim to make normative evaluations of any gender or group, but rather attempts to understand: under specific social and symbolic conditions, how subjects are generated, distributed, and maintain their stability in different ways.

相关论述仅为理论阐释，不构成对任何群体的描述、评价或规定。

引言：精神分析理论中的女性问题

Introduction: The Question of the Feminine in Psychoanalytic Theory

精神分析理论从诞生之初就面对着关于女性的理论困境。弗洛伊德曾坦承他对女性心理的困惑，提出那个著名的问题：”女性究竟想要什么？”这个问题标志着精神分析在女性问题上遭遇的结构性障碍。弗洛伊德试图通过一系列关于性别发展和情结的概念来理解女性主体的形成，但这些理论框架始终以男性发展模式为参照，将女性置于一个派生的、补充性的位置。这种理论困境不仅暴露了早期精神分析的局限，更深层地揭示了当时的理论系统在处理女性位置时的根本性难题。

From its inception, psychoanalytic theory has confronted theoretical dilemmas concerning the feminine. Freud candidly admitted his perplexity regarding feminine psychology, posing that famous question: “What does a woman want?” This question marks the structural obstacle that psychoanalysis encountered in addressing the feminine question. Freud attempted to understand the formation of the feminine subject through a series of concepts concerning sexual development and complexes, but these theoretical frameworks consistently took the masculine developmental model as their reference point, positioning the feminine in a derivative, supplementary location. This theoretical impasse not only exposed the limitations of early psychoanalysis but more profoundly revealed the fundamental difficulties of the theoretical system of that time in addressing the feminine position.

直到20世纪50至70年代拉康的理论出现，精神分析对于女性位置的理解才有了新的进展。拉康通过引入结构主义语言学和索绪尔的符号学理论，将精神分析重新奠基于符号秩序的分析之上[1]。在这个框架中，拉康提出了那个著名的断言：”La femme n’existe pas”（女人不存在）[2]。拉康的理论意涵在于：在符号系统的层面上，不存在一个可以完全界定、完全命名的”女性本质”。

It was not until the emergence of Lacan’s theory in the 1950s-70s that psychoanalysis made new progress in understanding the feminine position. By introducing structuralist linguistics and Saussure’s semiotic theory, Lacan re-founded psychoanalysis upon the analysis of the symbolic order[1]. Within this framework, Lacan proposed that famous assertion: “La femme n’existe pas” (Woman does not exist)[2]. Lacan’s theoretical implication is that: at the level of the symbolic system, there does not exist a “feminine essence” that can be completely defined or fully named.

这一论断的核心关涉拉康理论中主体如何被欲望构造、如何进入语言秩序、如何与他者的欲望发生关系的问题。在拉康看来，符号秩序作为一个以某个核心能指（拉康使用”Phallus”这个术语，此处指作为符号功能的能指，源于他对俄狄浦斯情结的符号化改造）为中心建构的系统，通过这个能指的”在场/缺席”来组织主体位置。在拉康的理论假设中，占据”男性位置”的主体能够通过认同父亲的符号位置，在这个”有/无”的区分系统中获得稳定定位，而占据”女性位置”的主体却始终处于这一逻辑之外。这里说的”之外”意味着无法被完全纳入这个符号体系。拉康认为，女性位置在符号中总是”多出来的、剩余的、不可完全命名的”，而这恰恰构成了他所说的某种特定主体结构的位置。在精神分析传统中，这种结构被称为”癔症主体”（sujet hystérique）。需要特别说明的是，这个术语在拉康理论中完全是一个技术性概念，指的是主体与符号秩序、与他者欲望的特定关系模式，这个概念与日常语言中的”癔症”或任何病理学意义之间存在根本差异。

在对“走向关系性存在”的可能性进行思考之后，随之而来的问题是：如果这一转向具有其意义，那么它需要哪些基础设施作为支撑？在本文中，“基础设施”被理解为一组条件，它们使关系性存在得以被理解、发生、维持、生成与延续。

After reflecting on the possibility of moving toward relational being, a subsequent question arises: if such a shift carries significance, what kinds of infrastructure would be required to support it? In this context, “infrastructure” is understood as a set of conditions that enable relational being to be understood, to occur, to be sustained, to generate, and to continue.

一、理论基础设施 / I. Theoretical Infrastructure

理论基础设施的功能在于使关系性存在可被思考、建模与传递。关系性范式需要一种非实体中心的形式语言，用于描述关系、变化与生成，从而避免将关系还原为经验直觉或修辞性表述。

在这一层面上，场论提供了一种理解非局域相互作用结构的形式直觉，使关系不再依附于孤立实体；群论通过对变换结构的刻画，引入了一种关系本体的形式承诺，使对象的同一性与结构来自关系的保持方式；过程哲学将存在理解为生成过程本身；网络理论与复杂系统理论则用于分析多主体关系中整体结构与新性质的涌现。这些理论并不提供终极解释，而是为关系性存在提供可组合、可演化的形式框架。

其关键特征体现在三个方面：以关系、过程或场为基本单元；强调生成与涌现作为理解存在的核心路径；具有跨层映射能力，能够在哲学、科学、社会与技术等不同层次间建立联系。

The function of theoretical infrastructure is to make relational being thinkable, modelable, and transmissible. It provides a non-entity-centered formal language for describing relations, change, and genesis, allowing relational being to be articulated without reduction to intuition or rhetoric.

At this level, field-theoretic perspectives offer formal intuitions for understanding non-local interaction structures, freeing relations from dependence on isolated entities; group theory introduces a formal commitment to relational ontology by describing structures in terms of allowable transformations, through which identity and structure are defined relationally; process philosophy understands being in terms of generative processes; and network theory and complex systems theory analyze emergent structures and properties in multi-agent relations. These theories do not offer ultimate explanations, but provide composable and evolvable formal frameworks for relational being.

Its key characteristics manifest in three aspects: taking relations, processes, or fields as basic units; emphasizing genesis and emergence as core modes of understanding being; and possessing cross-level mapping capabilities that connect philosophical, scientific, social, and technical dimensions.

Summary

理论基础设施用于为关系性存在提供可形式化、可建模的理解框架。
例：场论（非局域关系结构），群论（关系变换的本体承诺），过程哲学（生成过程的理解），网络理论，几何与拓扑理论，复杂系统理论。

Theoretical infrastructure provides formalizable and modelable frameworks for understanding relational being.
Examples: field theory (non-local relational structures), group theory (ontological commitment to relational transformations), process philosophy (understanding of generative processes), network theory, geometric and topological theories, complex systems theory.

引言 / Introduction

本文是对人类精神史的一次随想式思考，试图建立一个双重分类学框架。这一框架不仅描述了”是什么”(本体论层次)，更揭示了”如何生成”(生成性形态学层次)。通过这两个相互交织的维度，我们尝试理解从古代到现代，再到我们正在进入的新阶段的思想演进。这不是严格的学术研究，而是一次概念性的探索。

This essay is a casual reflection on the history of human spirit, attempting to establish a dual taxonomic framework. This framework not only describes “what is” (the ontological level), but also reveals “how it comes to be” (the morphology of genesis). Through these two interwoven dimensions, we attempt to understand the evolution of thought from antiquity to modernity, and into the new stage we are now entering. This is not rigorous academic research, but a conceptual exploration.

一、第一分类学：本体论层次 / I. First Taxonomy: The Ontological Level

“神性”在此不仅指宗教意义上的神圣，更指涉占据支配地位的终极权威与意义来源。我们用”神性”这一术语的统一性，是因为它本身已经蕴含了”主要性”，即在特定历史阶段中居于支配地位的东西。

“Divinity” here refers not only to the religious sense of the sacred, but more broadly to the ultimate authority and source of meaning that occupies a dominant position. We use the unified term “divinity” because it already embodies “primacy,” that which holds the dominant position in a particular historical stage.

第一阶段是超越性神性。在人类精神史的这一阶段，意义与秩序的源泉位于超越于人类经验之外的力量。无论是古代的诸神、自然的伟力，还是一神教的至高存在，权威都来自”彼岸”。人的存在是被动的、接受的，在一个预先给定的宇宙秩序中寻找自己的位置。这一阶段的特征是垂直性：真理从上而下降临，人只能仰望、敬畏、服从。

The first stage is transcendent divinity. At this stage of human spiritual history, the source of meaning and order lies in powers transcending human experience. Whether ancient deities, natural forces, or the supreme being of monotheism, authority comes from “beyond.” Human existence is passive and receptive, seeking its place within a pre-given cosmic order. This stage is characterized by verticality: truth descends from above, and humanity can only look up, revere, and obey.

第二阶段是符号性神性。启蒙运动标志着一个根本性的转折。神性的位置被符号系统、理性结构所占据。笛卡尔的”我思故我在”不仅是一个哲学命题，更是一场权威转移的宣言：人通过理性、逻辑、科学来把握世界，符号系统成为新的”神”。这里的”神性”是功能性的，理性占据了曾经属于神的位置：它是最高权威，是意义的源泉，是我们不可质疑的基础。这一阶段建立在主客二分之上，人作为理性主体试图通过符号化、形式化来控制客体世界。
