Post Doctoral Positions in Social Network Research

 

The Science of Networks in Communities (SONIC) Laboratory at Northwestern University (http://sonic.northwestern.edu)

invites applications for up to three post doctoral positions. SONIC lab members utilize and advance social network theories,

methods, and web-based tools to better understand and facilitate social networks in a variety of contexts, including

communities of practice; science, engineering, and medical communities; and communities involved in emergency response,

public health, climate change, and virtual worlds. Current research projects include several multi-year efforts funded in part

by the US National Science Foundation, National Institutes of Health, Army Research Institute, Army Research Laboratory,

Air Force Research Laboratory, MacArthur Foundation, and the City of Chicago. Hires will be expected to conduct social

network research in several of the on-going projects, to take leadership in initiating new interdisciplinary research projects,

and to co-mentor junior lab members. Hires will also have an affiliation with the Northwestern Institute on Complex Systems

(NICO; http://www.northwestern.edu/nico/) to facilitate interaction and collaboration with a broader community of

network researchers.

 

Key Responsibilities (one or more of the following):

 

• Develop theoretical and conceptual frameworks to investigate factors that leads to the formation, maintenance, and

dissolution of dynamically linked social and knowledge networks

• Utilize and extend methods for mathematical, statistical, and computational modeling of networks

• Develop and implement socio-technical algorithms for network recommender systems

• Utilize and develop innovative techniques for data collection, integration, and management of large-scale

multidimensional social networks from surveys and digital sources/traces

• Implement algorithms for modeling large-scale social networks in high performance (Petascale) computing

environments.

 

Qualifications: We invite applications from US and international scholars with PhDs from a wide variety of disciplines, with

interest and expertise in one or more of the following areas:

 

• Social scientific theories of network emergence and evolution

• Modeling of networks: mathematical, statistical, computational

• Web Science and Semantic Web technologies

• Data-mining algorithms to detect networks

• High performance and cloud computing

• Visualization of networks

 

Compensation: The appointment will carry an annual stipend commensurate with qualifications and experience in addition

to standard benefits provided to all employees of Northwestern University.

 

Application Procedures: Applicants must submit by email the following: 1) a curriculum vitae, including a list of

publications and prior research experience if applicable; 2) a brief statement of research interest and experiences relevant to

the activities of SONIC, and 3) names, affiliations, and contact information for three references. Send all application

materials as well as any inquiries to Professor Noshir Contractor, [log in to unmask]. Appointment starting date and

I'm trying to group them .. to form some crude typology based on, essentially, their ratio of structural holes. Simple star nets are obvious as are those with every alter in at least one dyad or triad. Some have small or large clusters of connected alters. And most have combinations of "singletons" (what Burt calls center-periphery), dyads, triads and clusters.. A search for papers describing a tentative typology has been fruitless. Could anyone point me to papers my search has missed?

(2010; ) have proposed a new indicator (MNCS) for field normalization. Since field normalization is also used in the Leiden Rankings of universities, we elaborate our critique of journal normalization in Opthof & Leydesdorff (2010; ) in this rejoinder concerning field normalization. Fractional citation counting thoroughly solves the issue of normalization for differences in citation behavior among fields. This indicator can also be used to obtain a normalized impact factor.

First: I assume that by "geodesic" you mean "shortest path", in which case the lengths of all shortest paths will (by definition) be the same, and so this matrix would not be able to distinguish between "lots of short paths" and "few long paths". Perhaps this is your intent, of course. Second: Depending on the topology of your network, there can be an exponential number of such paths connecting two vertices. So it may be worth reconsidering whether calculating this matrix is a good solution to whatever problem you're trying to solve.

If you want a short algorithm see page 63 in Batagelj, V: Semirings for social networks analysis. J Math Sociol 19 (1994)1: 53-68 You get two matrices.

Dear SOCNET members,

I am working on a weighted network and trying to calculate a matrix, each cell of which will be the sum of the weights of all the possible geodesics between any pair of nodes in the network.

Any suggestions on how to calculate such a matrix will be more than valuable.

Best regards,

You need to be clear if the geodesic distances use the weights or not.

Subject: [SOCNET] sum of weights of geodesics

 

Dear SOCNET members,

I am working on a weighted network and trying to calculate a matrix, each cell of which will be the sum of the weights of all the possible geodesics between any pair of nodes in the network.

Any suggestions on how to calculate such a matrix will be more than valuable.

Best regards,

Content preview: Patient Referral Patterns and the Spread of Hospital-Acquired Infections through National Health Care Networks , PLoS Comput Biol Summary: The prevalence of hospital acquired infections is widely believed to reflect the quality of health care in individual hospitals, and is therefore often used as a benchmark. Intuitively, the idea is that infections spread more easily in hospitals with a poor quality of health care. This assumes that the rate at which admitted patients introduce new infections is the same for all hospitals. In this article, we show that this assumption is unlikely to be correct. Using national data on patient admissions, we are able to reconstruct the entire hospital network consisting of patients referred between hospitals. This network reveals that university hospitals admit more patients that recently stayed in other hospitals. Consequently, they are more likely to admit patients that still carry pathogens acquired during their previous hospital stay. Therefore, the prevalence of infections does not only reflect the quality of health care but also the connectedness to hospitals from which patients are referred. This phenomenon is missed at the single hospital level; our study is the first to address the connectedness between hospitals in explaining the prevalence of hospital acquired infections. Our findings imply that interventions should focus on hospitals that are central in the network of patient referrals.

Natural selection typically favors individuals that maximize their own reproduction, so how is it that many diverse organisms, from bacteria to humans, have evolved to help others at a cost to themselves? Research has shown that cooperation can most readily evolve when cooperative individuals preferentially help each other, but this leaves open another critical question: How do cooperators achieve selective interaction with one another? We focus on this question in the context of unicellular organisms, such as bacteria, which exhibit simple forms of cooperation that play roles in nutrient acquisition and pathogenesis. We use a realistic simulation framework to model large cell groups, and observe that cell lines can spontaneously segregate from each other in space as the group expands. Finally, we demonstrate that lineage segregation allows cooperative cell types to preferentially benefit each other, thereby favoring the evolution of cooperation. * [17] Emergence of Spatial Structure in Cell Groups and the Evolution of Cooperation, Nadell CD, Foster KR, Xavier JB, 2010/03/19, DOI: 10.1371/journal.pcbi.1000716, PLoS Comput Biol 6(3): e1000716.

The evolutionary mechanisms associated with kinship and reciprocity, which underpin much of primate sociality, do not readily extend to large unrelated groups. Theory suggests that the evolution of such societies may have required norms and institutions that sustain fairness in ephemeral exchanges. If that is true, then engagement in larger-scale institutions, such as markets and world religions, should be associated with greater fairness, and larger communities should punish unfairness more. Using three behavioral experiments administered across 15 diverse populations, we show that market integration (measured as the percentage of purchased calories) positively covaries with fairness while community size positively covaries with punishment. * [18] Markets, Religion, Community Size, and the Evolution of Fairness and Punishment, Joseph Henrich, et al., 2010/03/19, DOI: 10.1126/science. 1182238, Science Vol. 327. no. 5972, pp. 1480 - 1484 [18] http://dx.doi.org/10.1126/science.1182238 Barry Wellman _______________________________________________________________________ S.D.

Apparently unrelated developments, which had been gradually unfolding for years, suddenly converge to create changes that are as disruptive as they are creative. We are currently living in a moment of extraordinary complexity when systems and structures that have long organized life are changing at an unprecedented rate. Such rapid and pervasive change creates the need to develop new ways of understanding the world and of interpreting our experience. (Marc C. Taylor, ďThe Moment of Complexity: Emerging Network CultureĒ) In the last decade there has been a growing interest in the study of complex systems. The concept of complexity is pervasive in many fields of research, from social sciences such as politics and economics to 'hard' sciences such as theoretical physics and systems biology. This growing interest and concurrent widening of research domains creates the need to develop new ways of understanding and interpreting the world. This is particularly important for young researchers tackling their initial research questions within the domain of complex systems. The Young Researchers Session @ ECCS2010 seeks to bring together a group of complex systems science researchers at an early stage in their careers (graduates, M.Sc., Ph.D., Postdoctoral researchers and Lecturers), to facilitate a dialogue beween individuals and groups from an intentionally diverse set of domains. We aim to encourage the presentation of experimental results within this supportive, interdisciplinary group, and to foster collaboration between people from within the complex systems community who may not otherwise have come across experimental techniques and approaches from outside their 'comfort zone'. Emphasis will therefore be on creating a stimulating and interactive environment, with a focus also on the bigger questions at large within complex systems research. To this end, presenters will be asked to allude to the 'bigger picture' questions within their domain and in complex systems science as a whole from their perspective. Crucially, we aim to establish a collaborative environment that will continue after ECCS2010 to foster these links. ======================================================================Meeting agenda ====================================================================== The workshop will take place on September 15th, 2010, and will focus on a limited number of pre-selected contributions, incorporating group discussions. Some important issues that may be discussed: * How to ensure a research activity trajectory from Ph.D. students to all early career researchers. * Research methodologies, tools, datasets and related problems. * Current research programs. * Current 'state of the art' experimental results within complex systems science. * How to set up social media presence for complex systems science young career researchers. * How to network curricula. Integration with online presentation of educational materials e.g. assystcomplexity.eu, videolectures.net * SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis of young researchers personal resources. * Ph.D. vs M.Sc. v's job opportunities. * What to publish, how to publish, when to publish. ======================================================================Invited Speakers ====================================================================== Vitorino Ramos - http://www.chemoton.org/ Anders Lyhne Christensen - http://iridia.ulb.ac.be/~alyhne/ ======================================================================Important dates ====================================================================== 30/4: Deadline for submissions 31/5: Notification of acceptance 10/6: Final (amended) manuscripts due 15/9: Satellite Meeting ======================================================================Call for presentations ====================================================================== Graduates, Masters and Ph.D. students are invited to submit a presentation as a short 300 word abstract on a subject within complex systems science or a longer (six pages) full scientific paper on topics concerning research and academic careers, complex systems domains and applications, job opportunities for complex systems science graduates, curriculum networking, skills matrices for complex systems sdudies as a whole or any other relevant matter. ======================================================================Paper Submission ====================================================================== It is adived the use of the LNCS format (not mandatory) http://www.springer.com/computer/lncs?SGWID=0-164-6-793341-0 To submit, please send the produced PDF to [log in to unmask] Papers should have 6 pages maximum (LNCS Format).

Models of science dynamics - encounters between complexity theory and information sciences

Editors: Andrea Scharnhorst; Katy Börner; Peter van den Besselaar

To appear in the Complexity Series of Springer

Call for chapter outlines and outline of the book

This book aims to review and describe major threads in mathematical modelling of the science system. The model classes we aim to cover are stochastic and statistical models, system dynamics approaches, agent-based simulations, population dynamics models, complex network models. This list should not be understood as exclusive. Other topics relevant in the context of the book are: Social network analysis and sociological models; entropy and information measures; role of geographic models; modelling individual scientific biographies; etc. Model classes often combine descriptive and predictive elements—this book places a strong emphasis on the latter. Each model class will be covered by one  chapter, which includes a general introduction, extended literature review, s ample  models and applications.

The book will also feature an introductory chapter that defines and operationalizes terminology used in the study of science and a review chapter that discusses and compares existing modelling approaches. These two chapters, will be made available in the beginning of the production processes to all authors, to avoid duplications and to enhance the coherence of the book. In addition, there will be a chapter on the communication of science modelling results by means of static, dynamic, and interactive visualizations. A chapter on future science modelling trends concludes the book. As editors we are also open to suggestions of additional chapters, e.g., on model validation, model application in science policy, etc.

The following list indicates possible chapters.

Chapter 1: Basic units of science, their aggregations and interlinkages, existing laws and model types.

Chapter 2: The history of modelling  science

Chapter 3: Statistical models and stochastic processes – from skew distributions to reliability of indicators

Chapter 4: System dynamic approaches to science modeling

Chapter 5: Agent-based modelling – from kenes to epistemic landscapes

Chapter 6: Population dynamic models and epidemic models – the diffusion of ideas

Chapter 7: Complex network models – from networks of citations to networks of collaboration

Chapter 8: Communicating modelling results– a new dynamic cartography of science

Chapter 9: Toward international science forecasts – real-time data analysis and modelling of global semantic S&T data

WE INVITE POSSIBLE AUTHORS TO SUBMIT AN OUTLINE OF THE CHAPTER (max. 4 pages) INCLUDING AN ABSTRACT ABOUT THE AREA, RESEARCH QUESTIONS AND MODELS COVERED BY THIS CHAPTER AND A PROVISIONAL TABLE OF CONTENT WITH HEADINGS OF THE SUBSECTIONS AND A TWO-LINE SUMMARY OF EACH SUBSECTION.

The book addresses a wider academic audience than specialists in mathematical modelling. We encourage authors to use a language style which corresponds to this envisioned audience.

Final chapters have to use Springer templates and will be around 20-25 pages (10 000 – 12 000 words) each.

I'm conducting network analysis of author/author citation network data. It was obtained by checking bibliographies of Russain sociological journals for references between St. Petersbourg sogiologists. I have 288x288 symmetric weighted adjacency matrix and several actor attributes (age cohort, institution, gender). My idea is to check, whether their mutual citation patterns coincide with their institutional relations. In order to do this, I need to aggregate them into clusters, subgroups, cliques etc. So, the question is: what approach and method should I use? Should it be cohensive networks or structural equivalence? CONCOR, cluster analysis or clique detection methods? I've read the articles, found in this listserve's archieve on citation network analysis, but they are mostly about co-citation, journal-to-journal citation, affiliation networks and so on. Any ideas?

It should not affect what we produce as theory, but it does. One set of people is at ease with discete objects: with sets, with relations described by a table, with abstract algebras performed on those tables (interpreted as matrices). White was demonstrating that mode with CONCOR. Another set of people is at ease withcontinua and variable, with analysis and conventional linear algebras. MDS comes out of this 'style'. De facto you will often find that the first CONCOR split will correspond to a line drawn across an MDS solution. De facto you will often find that the second CONCOR split will correspond to another line (or to two not quite connected lines) that divide the two regions established by the first line. Second problem, there is no such thing as THE solution by MDS. If I take a picture of my house, we can pretty well judge whether it is a good picture. If I compute an image of a network -- who knows? That's quite another matter (no reference point, no eyeball to look at the object directly and then compare it to the MDS image. You will find that different scaling procedures produce different maps -- a reality we normally try to make go away by using only one set of software. That does not solve the problem.

I guess you have your data already clustered by CONCOR, and you would like
to present the reduced blockmatrix by MDS?
When I run MDS directly in NetMiner it draws me a map with only a few visible actors. It seems like 90% of nodes are exactly in the centre and one-two are at the end of each axis. It's almost imposible to interpret such picture.† But when I check MDS as an output option in CONCOR, it shows me nice scatter plot with 3 distinctive axis and some dispersion. This picture corresponds with my substantive assumptions and very interesting for interpretation.
Anyhow, you will be much more exposed to criticism for adopting CONCOR, than
for using MDS...
Why? Unfortunatelly, I really doubt it =( Here in Russia there is only one thesis on SNA and only one book about it. And the author of both of them is my tutor. My search for SNA in local sociological journals revealed only 4 articles. So, this listserve is the only place for me to search an advice. That's why I'm asking such a noob questions.

"rarely used" - I think it is very often used.
I guess you have your data already clustered by CONCOR, and you would like
to present the reduced blockmatrix by MDS? That is fine.
You can also use MDS to represent the original structural similarity measure
matrix, and possibly include the centroids of CONCOR blocks.
Anyhow, you will be much more exposed to criticism for adopting CONCOR, than
for using MDS...

One of its founders has explicitly said that there is "[no] justification for advocating the iteration of [correlance coefficients] matrices as a method for analysis of data" (Schwartz 1977:266ff). Tha algorithm always produced 2 splits, and makes subsequent partitions quite arbitrary when it comes to which of these splits to split further. If there are strong arguments to use structural equivalence, perhaps it would be better to simply use the correlance matrix (distance-based or Pearson) and use MDS to plot these in two dimensions, subsequently interpreting this in combination with a dendrogram. Depending on the data, and what you are looking for, you should also look into regular equivalence (if that specific sociological notion of "roles" is applicable to your particular study). I might be wrong, but it was quite some time since I last saw a solid argument on the advantages of using the Concor algorithm.

One of its founders has explicitly said that there is "[no] justification for advocating the iteration of [correlance coefficients] matrices as a method for analysis of data" (Schwartz 1977:266ff). Tha algorithm always produced 2 splits, and makes subsequent partitions quite arbitrary when it comes to which of these splits to split further. If there are strong arguments to use structural equivalence, perhaps it would be better to simply use the correlance matrix (distance-based or Pearson) and use MDS to plot these in two dimensions, subsequently interpreting this in combination with a dendrogram. Depending on the data, and what you are looking for, you should also look into regular equivalence (if that specific sociological notion of "roles" is applicable to your particular study). I might be wrong, but it was quite some time since I last saw a solid argument on the advantages of using the Concor algorithm.
