 2Writing review articles 
 3Review articles
Review articles
- Something new to say about field / area 
 - New issues, insights, results, framework 
 - More than literature review 
 - Tutorial / overview of previous work and ideas 
 - General audience 
 - May be quantitative 
 - Meta-analyses e.g., 30 / 35 studies of 
endangered species reintroductions failed 
  4Review articles
Review articles
- Best reviews are synthetic 
 - Organize material to see bigger picture 
 - Bridge building to other disciplines 
 - New classification 
 - Cellular automata continuous vs discrete states 
 - Example Anderson, 2002 
 - See old material in new ways 
 - Point of view 
 - Take home message 
 - Why do we care?
 
  5Review articles
Review articles
-  To be comprehensive  balanced, 
acknowledge  - Controversies 
 - Hype 
 - Unresolved questions 
 - Recent developments 
 - Other viewpointsbe objective 
 - Conflicts / bias
 
  6Writing
Review articles
- Clarity  accuracy 
 - Single, clear narrative 
 - Tangential point 
 - Remove it 
 - Footnote it. Then remove it 
 - Organization 
 - Chronology 
 - Relationship 
 - Guiding theory, competing models, perspective 
 - Go against the grain what everyone thinks, why 
they think it, why I think otherwise 
  7Writing
Review articles
- Title 
 - Informative  Descriptive 
 - Memorable / Quirky 
 - The spandrels of San Marco and the Panglossian 
paradigm a critique of the adaptationist program  - The spaniels of St. Marx and the panglossian 
paradox,a critique of a rhetorical programme  - Use colon 
 - Live and let die why fighter males of the ant 
Cardiocondyla kill each other but tolerate their 
winged rivals Anderson et al., 2003  - Headings and subheadings 
 - Table of contents / explicit layout in text
 
  8Self-organization in relations to several similar 
concepts are the boundaries to self-organization 
indistinct?
Review articles
- Abstract / Introduction 
 - What is self-organization? 
 - Could a self-organized use global information? 
 - What is the role of the degree of correlation of 
activity among individuals?  - Qualitative versus quantitative stigmergy 
 - Qualitative versus self-assembly 
 - Self-assembly versus self-organization 
 - What is the role of positive feedback? 
 - Could self-assemblages involve positive feedback? 
 - Do some examples of self-organization lack 
positive feedback?  - Conclusions

Reviews should not be like phone books!
Impressive cast, lots of numbers, but not much 
plot
No mind-numbing lists of references
One can be comprehensive, but this detail can be 
relegated to tables and appendices

P. 552, Gopen  Ward, 1990
When the writer puts the emphatic material of a 
sentence in any place other than the stress 
position, one of two things can happen both are 
bad. First, the reader might find the stress 
position occupied by material that clearly is not 
worthy of emphasis The second possibility is 
even worse The reader may find the stress 
position occupied by something that  is 
inadvertently emphasized .the writer will have 
lost an important opportunity to influence the 
readers interpretative process. The stress 
position can change.

The first step towards clarity is to write simply 
and directly The second step toward clarity is 
to organize the manuscript so that An example

is An example of a review organized around a 
point is provided by

ants. During the assault?
Dont flip unnecessarily between alternative 
jargon to mix it up you may confuse the reader 
 23Paragraphs
Paragraphs
- Exercises 
 - Examine list of topics (in order) in your essay. 
Do they outline a story?  - Does each paragraph have a point? 
 - No point? Discard 
 - Too many points? Split paragraph
 
  24Sentence structure 
 25Subject verb separation
Sentences
- Do not have too many or too long parenthetical 
interruptions between subject and verb  - Carl, typically, for he is British and therefore 
it is deeply ingrained within his culture, likes 
to drink tea. 19 words 14 word subject-verb 
interruption  - Carl likes to drink tea this is perhaps 
unsurprising given that he is British and tea 
drinking is deeply ingrained within their 
culture. 5  18 words no interruption  
  26Stress position
Sentences
- Early in sentence old and familiar material 
 - Stress point new and unfamiliar 
 - Typically end of sentence 
 - Carl and his British friends love drinking tea. 
 - Not always, e.g. with semicolon () or colon () 
 - Carl likes to drink tea this is perhaps 
unsurprising given that he is British.  - Carl is a typical Brit he likes drinking tea, 
and he adores the queen.  - Carl is a typical Brit first, he likes drinking 
tea second, he adores the queen.  - Sentence too long more candidates for stress 
positions than available stress positions 
  27Crafting sentences
Sentences
- First things first subjects should be followed 
as soon as possible by their verb  - Units of discourse should serve a single function 
or make a single point  - Save the best for last information intended to 
be emphasized should appear at stress point 
  28The complexity of the colony also has 
consequences for the organisation of work within 
the colony. In addition to worker policing (see 
section III), reduced intracolony conflict in 
complex societies has another important 
consequence the type of social control. In small 
simple societies, as in the ponerine ant 
Dinoponera quadriceps Ref A, there is much 
aggression and direct control of colony activity 
by the queen or gamergate. Gamergates are 
mated reproductive workers in queenless ants Ref 
A. In effect, the reproductives centrally 
control simple conflict-ridden societies. 
However, in the relatively harmonious larger 
societies, colony control and decision-making 
tends to be decentralized. That is, workers react 
to local information and configurations and so 
are self-organized Refs B-E. Centralized 
control would be difficult or impossible in large 
colonies. However, decentralized control can be 
very adaptive at the colony level, even with very 
large colony sizes, and importantly does not 
necessarily require complexity at the individual 
level More Refs. Interestingly, there are 
theoretical reasons to suppose that a large 
decentralized colony can be both efficient and 
reliable Anderson  McShea, 2001
- Underline the topic sentence(s). 
 - Underline subject and verb for each sentence. 
 - Examine the stress points in each sentence. 
 - Consider the organization of the final sentence 
of main paragraph.
