Academic Writing Style Guide

Based on Nature Reviews journal conventions and academic writing best practices.

Core Principles

1. Prose-Based Writing (CRITICAL)

Academic proposals must read as flowing, connected prose—not as bulleted lists or enumerated points.

The hallmark of excellent academic writing is the ability to present complex ideas through coherent paragraphs with smooth transitions. Point-by-point enumeration (bullet points, numbered lists) should be used sparingly and only where truly necessary.

When lists ARE appropriate:

Research questions/objectives (a focused set of 2-4 items)
Timeline milestones (where tabular format genuinely aids clarity)
Technical specifications requiring precise enumeration

When to avoid lists:

Describing contributions (narrate them in context instead)
Explaining methodology (use flowing prose with transitions)
Presenting background information (integrate into paragraphs)
Discussing implications (weave into coherent narrative)

Transformation example:

Poor (point-by-point):

The main contributions include:

A novel segmentation algorithm

A multi-modal fusion framework

Clinical validation results

Better (prose-based):

This research is expected to advance the field through several interconnected contributions. The development of a novel segmentation algorithm will enable automated plaque detection with accuracy surpassing current methods. Building on this foundation, a multi-modal fusion framework will integrate complementary imaging data to capture plaque characteristics inaccessible to any single modality. Finally, rigorous clinical validation will establish the prognostic value of these computational biomarkers for predicting cardiovascular events.

2. Precision Over Impression

Say exactly what you mean
Avoid vague language
Define terms clearly
Quantify when possible

3. Evidence-Based Claims

Support assertions with citations
Distinguish fact from interpretation
Acknowledge uncertainty appropriately

4. Logical Flow

Clear paragraph structure
Explicit transitions
Coherent argumentation

5. Reader-Centered

Anticipate reader questions
Provide necessary context
Guide through complexity

Hedging Language (学术谦逊表达)

Why Hedging Matters

Academic writing requires appropriate epistemic humility. Hedging:

Reflects genuine uncertainty in research
Protects against overgeneralization
Maintains scholarly credibility
Invites scholarly dialogue

[Point] Machine learning approaches have shown considerable promise for
medical image analysis. [Evidence] Recent studies have demonstrated that
convolutional neural networks can achieve diagnostic accuracy comparable
to expert radiologists in detecting certain conditions (Smith et al., 2023;
Jones, 2024). [Evidence] Furthermore, these systems have been successfully
deployed in clinical settings, with one large-scale trial reporting a 15%
reduction in diagnostic errors (Chen et al., 2024). [Explanation] These
advances suggest that AI-assisted diagnosis could address the growing
shortage of medical imaging specialists while maintaining high standards
of care. [Link] However, significant challenges remain in ensuring the
generalizability of these systems across diverse patient populations.
