Call for papers, session at Theoretical Roman Archaeology Conference, Edinburgh 12-14 April 2018:

Formal Approaches to Complexity in Roman Archaeology: Exploring Complex Systems and Understanding Change

Part 1: Exploring Complex Systems
Part 2: Understanding Change

Session Organisers: Tom Brughmans (University of Oxford) – John W. Hanson (University of Colorado) – Matthew J. Mandich (University of Leicester) – Iza Romanowska (Barcelona Supercomputing Center) – Xavier Rubio-Campillo (University of Edinburgh)

In recent years archaeologists have increasingly employed innovative approaches used for the study of complex systems to better interpret and model the social, political, and economic structures and interactions of past societies. However, for the majority of Roman archaeologists these approaches remain elusive as a comprehensive review and evaluation is lacking, especially regarding their application in Roman archaeology.

In brief, a complex system is made up of many interacting parts (‘components’ or ‘agents’) which form a whole that is more than the sum of its parts – i.e. the interactions of these parts lead to emergent behaviors or outcomes that cannot be (easily) predicted by examining the parts individually. While such systems are characterized by their unpredictable, adaptive, and/or non-linear nature, they are (often) self-organising and governed by observable rules that can be analysed via various methods. For example, many past phenomena, such as urbanism or the functioning of the Roman economy, are complex systems composed of multiple interacting elements and driven by the diverse processes acting upon individuals inhabiting the ancient world. Thus, they can be explored using the approaches and methods of complexity science.

The study of complex systems has primarily been undertaken in contemporary settings, in disciplines such as physics, ecology, medicine, and economics. Yet, as the complex nature of ancient civilizations and their similarity to present-day  systems is being steadily realized through ongoing analysis, survey, and excavation, archaeologists have now begun to use methods such as scaling studies (e.g. settlement scaling theory), agent-based modeling, and network analyses to approach this complexity. Since these methodologies are designed to examine the interactions and feedback between components within complex systems empirically, they can provide new ways of looking at old data and old problems to supply novel conclusions. However, such methods have only been applied sporadically in ancient settings, and even less so in a Roman context or using Roman archaeological data.
Thus, in this two part session we aim to bring these methods, and the Roman archaeologists using them, together by offering a critical review of the theoretical and empirical developments within the study of past complex systems and their interplay with existing ideas, before investigating how we might capitalize on the new opportunities afforded by them in the future. Part I of this session, ‘exploring complex systems’, is concerned with examining and unraveling the underlying structures present in the archaeological record using the formal tools provided by the complex systems framework. Part II, ‘understanding change’, will focus on applications exploring the dynamics of change that generated the patterns observed in existing evidence. In particular, we invite contributions using formal methods including computational modelling and simulation, GIS, and network analyses, as well as diverse theoretical approaches to better understand ancient complex systems.

CFP CFP Evolution of Cultural Complexity at Conference on Complex System, Cancun, September

I can recommend presenting at this event. I’ve been assured network talks are welcome!
Deadline CFP: 26 May
Where? Cancun, Mexico
We are pleased to announce a call for abstracts for our session on “Evolution of Cultural Complexity” at the annual “Conference on Complex System”. The Conference on Complex System will takes place this year in Cancun, Mexico, from the 17th to the 22nd of September. Our session will take pace on the 21st of September.
 
Human sociocultural evolution has been documented throughout the history of humans and earlier hominins. This evolution manifests itself through development from tools as simple as a rock used to break nuts, to something as complex as a spaceship able to land man on other planets. Equally, we have witnessed evolution of human population towards complex multilevel social organisation.
Although cases of decrease and loss of this type of complexity have been reported, in global terms it tends to increase with time. Despite its significance, the conditions and the factors driving this increase are still poorly understood and subject to debate. Different hypothesis trying to explain the rise of sociocultural complexity in human societies have been proposed (demographic factor, cognitive component, historical contingency…) but so far no consensus has been reached.
Here we raise a number of questions:
 
  1. Can we better define sociocultural complexity and confirm its general tendency to increase over the course of human history?
  2. What are the main factors enabling an increase of cultural complexity?
  3. Are there reliable way to measure the complexity in material culture and social organisation constructs, that is?
  4. How can we quantify and compare the impact of different factors?
  5. What causes a loss of cultural complexity in a society? And how often these losses occurred in the past?
 
In this satellite meeting we want to bring together a community of researchers coming from different scientific domains and interested in different aspect of the evolution of social and cultural complexity. From archaeologists, to linguists, social scientists, historians and artificial intelligence specialists – the topic of sociocultural complexity transgresses traditional discipline boundaries. We want to establish and promote a constructive dialogue incorporating different perspectives: theoretical as well as empirical approaches, research based on historical and archaeological sources, as well as actual evidences and contemporary theories.
 
Submissions will be made by sending an abstract in PDF  (maximum 250 words) via Easychair here: https://easychair.org/conferences/?conf=eec2017 . The deadline for abstract submission is on the 26th of May 2017. The contributions to this satellite will be evaluated by the scientific committee through a peer review process that will evaluate the scientific quality and the relevance to the goal of this session. Notification of accepted abstracts will be communicated by the 4th of June 2017.
 
Please find more details on the following website: https://ccs17.bsc.es/
We strongly encourage you to participate  


Please help us to spread the word!

Announcing the complex systems simulation CAA special interest group

complexityThe last CAA meeting in Siena saw the creation of a new special interest group in complex systems simulation. This new group will be of interest to network fans as well. The chairs Iza Romanowska, Florencia del Castillo and Juan Antonio Barceló have plans to organise sessions, workshops and networking events around the CAA conferences and independently. They will use the Simulatingcomplexity blog as well as their mailing list to keep you informed on their activities and to offer help to those who wish to apply complex systems simulation techniques to their work. Subscribe!

Want to know what it’s all about? A word from the chairs:

The staggering complexity of past societies is well recognised in archaeology. Human groups often built intricate social systems, which consist of numerous individual elements interacting with each other and with the environment and producing phenomena that are not easy to anticipate or understand using non-quantitative methods. The standard scientific answer to the challenges of investigating such systems is the large family of simulation techniques and the theoretical paradigm known as Complexity Science. In the last few years these approaches (agent-based and equation-based modelling, systems dynamics, cellular automata, network analysis etc.), have become increasingly popular among the practitioners of archaeological computing, suggesting that the time is right to bring this growing community together.

Therefore, the aim of the new Special Interest Group in Complex Systems Simulation is to provide a strong communication platform for present and future researchers working in the complex systems simulation domain. In particular, we will strive to:

  • provide continuity to the sessions and workshops concerned with computational modelling at the annual CAA conference and beyond,
  • organise, coordinate and inform the members of other events related to complexity science and simulation,
  • organise events aimed at training future complex systems modellers and the general archaeological audience,
  • define and promote good practices in archaeological computational modelling,
  • and, in the long term, we hope to bring simulation and other complexity science methods into mainstream archaeological practice.

To join the SIG simply sign up to the mailing list and join us at the sessions and workshops dedicated to simulation and complexity science at CAA 2016 in Oslo!

Simulation is not new in archaeology. However, the last decade knew an increased focus among archaeologists in the use of simple computational models used to evaluate processes which may have operated in the past. Rather than all-encompassing reconstructions of the prehistoric world, models have been used as ‘virtual labs’ or ‘tools to think with’, permitting archaeologists to explore hypothetical processes that give rise to archaeologically attested structures. Computational modelling techniques such as equation-based, statistical, agent-based and network-based modelling are becoming popular for quickly testing conceptual models, creating new research questions and better understand the workings of complex systems. Complexity science perspectives offer archaeology a wide set of modelling and analytical approaches which recognise the actions of individual agents on different scales who collectively and continually create new cultural properties.

This session aims to bring together complex systems simulation applications in archaeology. We invite innovative and critical applications in analytical and statistical modelling, ABM, network analysis and other methods performed under the broad umbrella of complexity science. We hope this session will spark creative and insightful discussion on the potentials and limitations of complexity science, its many simulation techniques and the future of modelling in archaeology.

WORKSHOP ABSTRACT

W1: Complex Systems and Agent-Based Modelling in Archaeology
Chairs: E. Ch’ng, C. Vegvari
Discussants: I. Romanowska, T. Brughmans

Modelling in various forms has always been an integral part of archaeology. In the broadest sense, archaeology is the study of human activities in the past, and a model is a simplified representation of reality. As a map is a useful abstract of the physical world that allows us to see aspects of the world we chose to, so a computational model distils reality into a few key features, leaving out unnecessary details so as to let us see connections. Human societies in their environmental context can be considered as complex systems. Complex systems are systems with many interacting parts, they are found in every hierarchy of the universe, from the molecular level to large planetary systems within which life and humanity with its cultural developments occur. Formal modelling can help archaeologists to identify the relationships between elements within a complex socio-environmental system in that particular hierarchy. Simulating large populations and non-linear interactions are computationally expensive. In recent years, however, the introduction of new mathematical techniques, rapid advances in computation, and modelling tools has greatly enhanced the potential of complex systems analysis in archaeology. Agent-Based Modelling (ABM) is one of these new methods and has become highly popular with archaeologists. In Agent-Based Modelling, human individuals in ancient societies are modelled as individual agents. The interaction of agents with each other and with their environment can give rise to emergent properties and self-organisation at the macro level – the distribution of wealth within a society, the forming of cohesive groups, population movements in climate change, the development of culture, and the evolution of landscape use are among the examples. Thus, the application of Agent-Based Models to hypothesis testing in archaeology becomes part of the question. The ability to construct various models and run hundreds of simulation in order to see the general developmental trend can provide us with new knowledge impossible in traditional approaches. Another advantage of agent-based models over other mathematical methods is that they can easily model, or capture heterogeneity within these systems, such as the different characteristics (personalities, gender, age, size, etc), preferences (coastal, in-land, food, fashion), and dynamics (microstates of position and orientation).

We would like to invite archaeologists new to complex systems and Agent-Based Modelling for an introductory workshop on Complex Systems and Agent-Based Modelling in archaeology. The workshop introduces the concept of Complexity in archaeology, drawing relationships between Information, Computation and Complexity. The practicality of the workshop leads beginners in building simple agent- based models and provides a means to build more complex simulations after. Participants knowledgeable in Complexity wishing to gain insights on real-world applications of Complexity will benefit from this workshop. Participants will get the opportunity to experiment with simple models and draw conclusions from analysis of simulations of those models. Programming experience is not required as the workshop leads beginners from the ground up in modelling tools.

Connected Island: Citation Network Analysis

In two previous blogposts (1, 2) I introduced the amazing Connected Island project Iza and I have been working on recently. This third blogpost about the Connected Island project will introduce our method for analysing publications and their citations. We will briefly discuss how citation network analysis works and the issues surrounding its applications. Finally, we will look at the very first results of this project: an analysis of publications about the Middle and Lower Palaeolithic in Hungary.

Citation network analysis

Recently, a wider availability of powerful computational resources, bibliometric software (e.g. HISTCITE; PAJEK; PUBLISH OR PERISH) and large bibliographic datasets in the sciences as well as the humanities resulted in significant progress in the analysis of citation networks in which vertices represent publications and a directed edge (or arc) between two vertices indicates a citation (Eom and Fortunato, 2011).

The foundations of citation network analysis were laid by Garfield et al. (1964) and the application of graph theory for citation network analysis was subsequently explored by Garner (1967). Despite this long tradition, its use in an archaeological context has not yet been thoroughly explored. In a number of studies researchers used simple counts of citations or other bibliometric data to track trends in the archaeological sciences and compare the impact and evolution of archaeological journals (e.g. Butzer, 2009; Marriner, 2009; Rehren et al., 2008; Rosenswig, 2005; Sterud, 1978), or to evaluate the impact of gender differentiation in archaeology (e.g. Beaudry and White, 1994; Hutson, 2002; 2006; Victor and Beaudry, 1992).

Citation network analyses in the Arts and Humanities are rare (Leydesdorff et al., 2011). The main reason for this is that the available citation databases for the Arts and Humanities (in particular the Institute for Scientific Information’s Arts and Humanities Citation Index) have significant limitations (Nederhof, 2006): books were until recently not indexed and publications in languages other than English are rare. However, monographs (rather than peer-reviewed journal articles) are often the dominant format of cited sources in the Humanities. Disciplines in the Arts and Humanities also show very different citation patterns and should therefore be considered separately (Knievel and Kellsey 2005). Despite these shortcomings citation analyses in the Arts and Humanities should not be discarded out of hand as it can still provide an alternative look at scientific practice through large aggregated datasets as long as the nature of the datasets and their limitations are thoroughly understood.

We came across some of these obstacles very early on during data collection for this project. Existing citation databases, like Web of Knowledge, contained only a fraction of the publications we were interested in. Those that are indexed in this resource are mostly written in English by Western European researchers (with a few exceptions) and it only rarely includes publications in Hungarian, Polish, Czech, Slovakian, or Russian. Manual data collection was therefore necessary.

A first test: the Lower and Middle Palaeolithic in Hungary

As a test-case we explored a small part of the project’s dataset, containing the 31 synthetic publications about the Lower and Middle Palaeolithic in Hungary we found in Budapest’s libraries. This collection of publications was written by nine Hungarian archaeologists between 1945 and 1990. This case-study aims to explore the citation patterns between them.

One would expect the older publications to be the most prominent since these had the time to accumulate the largest number of citations, and the results do show this process to some extent. Using the input domain measure (de Nooy et al., 2005: p. 193) we found that a few publications from the 50’s and early 60’s can be connected to by a larger number of nodes than any of the publications from the late 60’s and later, which indicates that these few publications influenced (directly or indirectly) the largest number of other publications. All of these publications with a high input domain were in fact written by a single author László Vértes who, although being very often cited by his colleagues, is guilty of quite a bit of self-citation as well. Although self-citation is common in academia and completely understandable (one always builds on one’s previous research), we needed to evaluate to what extent this affects the analytical techniques used. In this case the input domain seems to reflect largely the citation behaviour of one scholar who was extremely active throughout several decades.
Input domain score of publications: the number of publications that can be connected to a certain publication via a sequence of citations. This reflects the potential field of influence of a publication.
Input domain score of publications: the number of publications that can be connected to a certain publication via a sequence of citations. This reflects the potential field of influence of a publication.

Another way of evaluating the relative prominence of old and more recent publications is to look at the number of citations they received. It is interesting to note that the oldest as well as the recent publications receive a relatively small number of citations compared to a few publications from the mid- to late-60‘s. One of these is a monograph edited by Vértes on one of the most important Middle Palaeolithic sites in Hungary, Tata, which also received a high input domain score. The second highly cited publication was a book about the Middle Palaeolithic in Hungary also written by Vértes. The third most frequently cited work is a monograph about another prominent Middle Palaeolithic site, Érd, written by Veronika Gábori-Csánk.

In citation network analysis authoritative sources are often defined as publications that receive a high number of citations and particularly from so-called hubs. Hubs are defined as publications that cite a lot of other works especially authorities. Given these definitions we can identify the site monographs of Tata and Érd as well as the second highly cited book by Vértes as such authorities. The hubs in this network are three publications by the same authors: Miklos Gábori. All three of these publications are reviews of the Hungarian Palaeolithic and due to their very nature will include a lot of references, especially to key site reports.

The above measures very much over-emphasize the most cited publications and the work of the most active authors. We should note, however, that six works in this citation network are not cited or do not cite any others. These include publications from the 60’s by Vértes and Gabori, a few publications from the 50’s that seem to have been ignored by all those who followed, and the most recent publications from 1988 and 1990 that could not have been cited by others in this network.

Language of Publication

On the basis of the small sample of publications gathered in Budapest we can say that the widely held assumption that archaeological data from Central Europe was published in local languages is incorrect (Table 2). At least half, if not more, of Central European archaeology publications from this period were published in German, French or English alongside the national language. The image that all countries under the influence of the former Soviet Union published in Russian is incorrect.

Conclusions

We can conclude that although the effects of self-citation were definitely felt in this analysis, especially by those authors of whom we included multiple publications like Vértes or Gábori-Csánk, there are a number of publications that can be considered most pivotal in Hungarian Palaeolithic studies. These include the site reports of Tata and Érd.

Contrary to popular believe, Hungarian authors rarely published in their own language. Especially key site reports and synthetic works were written in these foreign languages, making them accessible to Western European archaeologists.

This blog post has explored the citation behaviour within a subset of the project’s dataset, and has concluded that Hungarian Palaeolithic archaeologists cited Central European and famous Western European scholars almost equally. Publications were almost always written in English, French or German, in addition to Hungarian, making most of them accessible to Western European archaeologists. But did the latter build on the work done by their Hungarian colleagues to improve their understanding of the European Lower and Middle Palaeolithic? Future work in this project will focus on the interactions between Western and Central European researchers.
