Sociology Beyond Societies : Mobilities for the Twenty First Century

John Urry — 2005-05-27T19:46:45-00:00

(25 November 1999)

In this ground-breaking contribution to social theory, John Urry argues that, if sociology is to make a pertinent contribution to the global era, it must abandon its original aim--the study of society as a set of institutions--and switch focus instead to the study of both physical and virtual movement.

(2003)

This paper describes a study investigating the potential for two user modelling systems: a location-aware user modelling system providing easy access to applications, files and course materials commonly used by an individual student in different locations; and a mobile open learner model for consultation by a student away from the intelligent tutoring system in which the learner model was generated.

Pervasive Computing and Communications, 2006. PerCom 2006. Fourth Annual IEEE International Conference on (2006), pp. 22-35.

In mobile computing environments, handheld devices with low functionality restrict the services provided for mobile users. We propose a new concept of collaborative browsing, where mobile users collaboratively browse web pages designed for desktop PC. In collaborative browsing, a web page is divided into multiple components, and each is distributed to a different device. In mobile computing environments, the number of handheld devices, their capabilities, and other conditions can vary widely amongst mobile users who want to browse content. Therefore, we developed a page partitioning method for collaborative browsing, which divides a web page into multiple components. Moreover, we designed and implemented a collaborative web browsing system in which users can search and browse their target information by discussing and watching partial pages displayed on multiple devices.

Revisiting the Visit: Understanding How Technology Can Shape the Museum Visit

R Grinter — 2006-08-01T02:18:45-00:00

(2002)

This paper reports findings from a study of how a guidebook was used by pairs of visitors touring a historic house. We describe how the guidebook was incorporated into their visit in four ways: shared listening, independent use, following one another, and checking in on each other. We discuss how individual and groupware features were adopted in support of different visiting experiences, and illustrate how that adoption was influenced by social relationships, the nature of the current visit,...

On the Move: Technology, Mobility, and the Mediation of Social Time and Space

N Green — 2005-10-26T13:53:59-00:00

The Information Society, Vol. 18, No. 4. (1 July 2002), pp. 281-292.

The current explosion in mobile computing and telecommunications technologies holds the potential to transform "everyday" time and space, as well as changes to the rhythms of social institutions. Sociologists are only just beginning to explore what the notion of "mobility" might mean when mediated through computing and communications technologies, and so far, the sociological treatment has been largely theoretical. This article seeks instead to explore how a number of dimensions of time and space are being newly reconstructed through the use of mobile communications technologies in everyday life. The article draws on long-term ethnographic research entitled "The Socio-Technical Shaping of Mobile Multimedia Personal Communications," conducted at the University of Surrey. This research has involved ethnographic fieldwork conducted in a variety of locales and with a number of groups. This research is used here as a resource to explore how mobile communications technologies mediate time in relation to mobile spaces. First the paper offers a review and critique of some of the major sociological approaches to understanding time and space. This review entails a discussion of how social practices and institutions are maintained and/or transformed via mobile technologies. Ethnographic data is used to explore emerging mobile temporalities. Three interconnected domains in mobile time are proposed: rhythms of mobile use, rhythms of mobile use in everyday life, and rhythms of mobility and institutional change. The article argues that while these mobile temporalities are emerging, and offer new ways of acting in and perceiving time and space, the practical construction of mobile time in everyday life remains firmly connected to well-established time-based social practices, whether these be institutional (such as clock time, "work time") or subjective (such as "family time").

Social Networks and Collective Action: A Theory of the Critical Mass. III

Gerald Marwell — 2006-05-09T23:38:57-00:00

The American Journal of Sociology, Vol. 94, No. 3. (1988), pp. 502-534.

Most analyses of collective action agree that overcoming the freerider problem requires organizing potential contributors, thus making their decisions interdependent. The potential for organizing depends on the social ties in the group, particularly on the overall density or frequency of ties, on the extent to which they are centralized in a few individuals, and on the costs of communicating and coordinating actions through these ties. Mathematical analysis and computer simulations extend a formal microsocial theory of interdependent collective action to treat social networks and organization costs. As expected, the overall density of social ties in a group improves its prospects for collective action. More significant, because less expected, are the findings that show that the centralization of network ties always has a positive effect on collective action and that the negative effect of costs on collective action declines as the group's resource or interest heterogeneity increases. These nonobvious results are due to the powerful effects of selectivity, the organizer's ability to concentrate organizing efforts on those individuals whose potential contributions are the largest.

Apprenticeship in Thinking: Cognitive Development in Social Context

Barbara Rogoff — 2005-09-29T00:10:41-00:00

(1990)

This interdisciplinary work presents an integration of theory and research on how children develop their thinking as they participate in cultural activity with the guidance and challenge of their caregivers and other companions. The author, a leading developmental psychologist, views development as an apprenticeship in which children engage in the use of intellectual tools in societally structured activities with parents, other adults, and children. The author has gathered evidence from various disciplines--cognitive, developmental, and cultural psychology; anthropology; infancy studies; and communication research--furnishing a coherent and broadly based account of cognitive development in its sociocultural context. This work examines the mutual roles of the individual and the sociocultural world, and the culturally based processes by which children appropriate and extend skill and understanding from their involvement in shared thinking with other people. The book is written in a lively and engaging style and is supplemented by photographs and original illustrations by the author.

Designing argumentation for conceptual development

Andrew Ravenscroft — 2006-01-09T10:34:05-00:00

Computers & Education, Vol. 34, No. 3-4. (1 April 2000), pp. 241-255.

If Virtual Learning Environments are to support real learning, they must promote effective teaching-learning processes and interactions. In this paper we describe a collaborative, computer-based framework for argumentation that supports the dialogue process in ways which stimulate belief revision leading to conceptual change and development in science. This pedagogy is specified as a prescriptive ‘dialogue game’, which models features of the tutorial process. Within this scheme, the learner adopts the role of an ‘explainer’ whilst the system plays a facilitating role, and these participants collaborate to develop a shared explanatory model of a qualitative, causal domain. The design framework includes an abstract world model of a qualitative causal system, some ‘commonsense’ reasoning rules, an interaction language and dialogue strategies and tactics, that are co-ordinated within a facilitating dialogue game. A prototype CoLLeGE (Computer based Lab for Language Games in Education) system implements the framework and operates as a dialogue modelling work-bench for demonstrating, investigating and developing the approach. An empirical study showed that students revised their beliefs and improved their explanatory models, and held to their revised and improved conceptions in a delayed post-test. In using CoLLeGE to simulate these dialogues, we found that the tutor’s low-level tactical pedagogies emerged and developed reactively during the dialogues, in response to conceptual difficulties experienced by the students.

The Uses of Argument

Stephen Toulmin — 2005-06-23T15:53:39-00:00

(07 July 2003)

This reissue of the modern classic on the study of argumentation features a new Introduction by the author. A central theme throughout the impressive series of philosophical books and articles Stephen Toulmin has published since 1948 is the way in which assertions and opinions concerning all sorts of topics, brought up in everyday life or in academic research, can be rationally justified. Is there one universal system of norms, by which all sorts of arguments in all sorts of fields must be judged, or must each sort of argument be judged according to its own norms? In The Uses of Argument (1958) Toulmin sets out his views on these questions for the first time. In spite of initial criticisms from logicians and fellow philosophers, The Uses of Argument has been an enduring source of inspiration and discussion to students of argumentation from all kinds of disciplinary background for more than forty years.

Friendster and publicly articulated social networking

Danah Boyd — 2005-06-25T23:21:43-00:00

(2004), pp. 1279-1282.

This paper presents ethnographic fieldwork on Friendster, an online dating site utilizing social networks to encourage friend-of-friend connections. I discuss how Friendster applies social theory, how users react to the site, and the tensions that emerge between creator and users when the latter fails to conform to the expectations of the former. By offering this ethnographic piece as an example, I suggest how the HCI community should consider the co-evolution of the social community and the underlying technology.

Digital Artifacts for Remembering and Storytelling: PostHistory and Social Network Fragments.

Fernanda Viégas — 2006-03-16T02:41:32-00:00

(2004)

As part of a long-term investigation into visualizing email, we have created two visualizations of email archives. One highlights social networks while the other depicts the temporal rhythms of interactions with individuals. While interviewing users of these systems, it became clear that the applications triggered recall of many personal events. One of the most striking and not entirely expected outcomes was that the visualizations motivated retelling stories from the users’ pasts to others. In this paper, we discuss the motivation and design of these projects and analyze their use as catalysts for personal narrative and recall.

Swarm Intelligence : From Natural to Artificial Systems (Santa Fe Institute Studies on the Sciences of Complexity)

Eric Bonabeau — 2006-03-14T12:59:22-00:00

(23 September 1999)

Social insects--ants, bees, termites, and wasps--can be viewed as powerful problem-solving systems with sophisticated collective intelligence. Composed of simple interacting agents, this intelligence lies in the networks of interactions among individuals and between individuals and the environment. A fascinating subject, social insects are also a powerful metaphor for artificial intelligence, and the problems they solve--finding food, dividing labor among nestmates, building nests, responding to external challenges--have important counterparts in engineering and computer science. This book provides a detailed look at models of social insect behavior and how to apply these models in the design of complex systems. The book shows how these models replace an emphasis on control, preprogramming, and centralization with designs featuring autonomy, emergence, and distributed functioning. These designs are proving immensely flexible and robust, able to adapt quickly to changing environments and to continue functioning even when individual elements fail. In particular, these designs are an exciting approach to the tremendous growth of complexity in software and information. Swarm Intelligence draws on up-to-date research from biology, neuroscience, artificial intelligence, robotics, operations research, and computer graphics, and each chapter is organized around a particular biological example, which is then used to develop an algorithm, a multiagent system, or a group of robots. The book will be an invaluable resource for a broad range of disciplines.

Cluster size distribution of infection in a system of mobile agents

MC Gonzalez — 2006-03-13T11:51:33-00:00

(28 Feb 2005)

Clusters of infected individuals are defined on data from health laboratories, but this quantity has not been defined and characterized by epidemy models on statistical physics. For a system of mobile agents we simulate a model of infection without immunization and show that all the moments of the cluster size distribution at the critical rate of infection are characterized by only one exponent, which is the same exponent that determines the behavior of the total number of infected agents. No giant cluster survives independent on the magnitude of the rate of infection.

Scaling of the propagation of epidemics in a system of mobile agents

MC Gonzalez — 2006-03-13T11:51:15-00:00

(17 Feb 2004)

For a two-dimensional system of agents modeled by molecular dynamics, we simulate epidemics spreading, which was recently studied on complex networks. Our resulting network model is time-evolving. We study the transitions to spreading as function of density, temperature and infection time. In addition, we analyze the epidemic threshold associated to a power-law distribution of infection times.

Opinion Formation on a Deterministic Pseudo-fractal Network

MC Gonzalez — 2006-03-13T11:50:59-00:00

(23 Jul 2003)

The Sznajd model of socio-physics, that only a group of people sharing the same opinion can convince their neighbors, is applied to a scale-free random network modeled by a deterministic graph. We also study a model for elections based on the Sznajd model and the exponent obtained for the distribution of votes during the transient agrees with those obtained for real elections in Brazil and India. Our results are compared to those obtained using a Barabasi-Albert scale-free network.

Model of mobile agents for sexual interactions networks

MC Gonzalez — 2006-03-13T11:48:02-00:00

(19 Aug 2005)

We present a novel model to simulate real social networks of complex interactions, based in a granular system of colliding particles (agents). The network is build by keeping track of the collisions and evolves in time with correlations which emerge due to the mobility of the agents. Therefore, statistical features are a consequence only of local collisions among its individual agents. Agent dynamics is realized by an event-driven algorithm of collisions where energy is gained as opposed to granular systems which have dissipation. The model reproduces empirical data from networks of sexual interactions, not previously obtained with other approaches.

Cycles and clustering in bipartite networks

Pedro Lind — 2006-03-13T11:47:48-00:00

(11 Apr 2005)

We investigate the clustering ability in bipartite networks where cycles of size three are absent and therefore the standard definition of clustering coefficient cannot be used. Instead, we use another coefficient given by the fraction of cycles with size four, showing that both coefficients yield the same clustering properties. The new coefficient is computed for two networks of sexual contacts, one monopartite and another bipartite. In both cases the clustering ability is similar. Furthermore, combining both clustering coefficients we deduce an expression for estimating cycles of larger size, which improves previous estimations and is suitable for either monopartite and multipartite networks.

Coherence in scale-free networks of chaotic maps

Pedro Lind — 2004-11-22T00:17:30-00:00

(17 November 2004)

We study fully synchronized states in scale-free networks of chaotic logistic maps as a function of both dynamical and topological parameters. Three different network topologies are considered: (i) random scale-free topology, (ii) deterministic pseudo-fractal scale-free network, and (iii) Apollonian network. For the random scale-free topology we find a coupling strength threshold beyond which full synchronization is attained. This threshold scales as $k^-μ$, where $k$ is the outgoing connectivity and $μ$ depends on the local nonlinearity. For deterministic scale-free networks coherence is observed only when the coupling strength is proportional to the neighbor connectivity. We show that the transition to coherence is of first-order and study the role of the most connected nodes in the collective dynamics of oscillators in scale-free networks.

A system of mobile agents to model social networks

MC Gonzalez — 2006-03-12T18:09:08-00:00

(14 Feb 2006)

We propose a model of mobile agents to construct social networks, based on a system of moving particles by keeping track of the collisions during their permanence in the system. We reproduce not only the degree distribution, clustering coefficient and shortest path length of a large data base of empirical friendship networks recently collected, but also some features related with their community structure. The model is completely characterized by the collision rate and above a critical collision rate we find the emergence of a giant cluster in the universality class of two-dimensional percolation. Moreover, we propose possible schemes to reproduce other networks of particular social contacts, namely sexual contacts.

Ontologies Are Us: A Unified Model of Social Networks and Semantics

Peter Mika — 2006-03-09T13:17:09-00:00

(2005), pp. 522-536.

In our work we extend the traditional bipartite model of ontologies with the social dimension, leading to a tripartite model of actors, concepts and instances. We demonstrate the application of this representation by showing how community-based semantics emerges from this model through a process of graph transformation. We illustrate ontology emergence by two case studies, an analysis of a large scale folksonomy system and a novel method for the extraction of community-based ontologies from Web pages.

Programming as mathematical narrative

Yishay Mor — 2006-03-07T17:13:43-00:00

International Journal of Continuing Engineering Education and Life-Long Learning (IJCEELL) (submitted)

This paper describes a narrative-oriented approach to the design of a computational system and a set of activities for mathematical learning. Mathematics and narrative would appear to be antithetical. Our central contention is that programming can offer a key to resolving the tension between the different representational structures of narrative and mathematical formalism. We see programming as an expressive activity, a form of writing or composing, embedded in social contexts and used purposefully to carry out actions. We claim that programming affords a narrative form for representing mathematical meanings; that learning to program can be concerned with the development of cognitive schemas, and perhaps even the transformation of social relationships. In the course of portraying our approach, we make a distinction between the epistemic-cognitive elements of narrative and the affective elements. We believe that this distinction will be of value in other domains as well. We propose a link between narrative theories of learning and constructionist traditions, specifically the notion of situated abstraction. This link suggests the possibility of further dialogue between the two academic communities. We begin by giving a brief account of the use of narrative in educational theory. We draw on two case studies derived from the WebLabs project (www.weblabs.eu.com) which combines a programming environment, ToonTalk and a web-based collaboration system designed to foster mathematical thinking and expression. We then describe our narrative-oriented framework, by using it to analyze both the environment and the experimental situations described.

Success and Failure in Mathematics: The Flexible Meaning of Symbols as Process and Concept

David Tall — 2006-03-07T13:44:32-00:00

Mathematics Teaching, Vol. 142 (1993), pp. 6-10.

Mathematics is an enigmatic subject in which a few succeed with disarming ease, whilst others seem doomed to failure. After analysing the responses of many children performing simple tasks in arithmetic, we find a phenomenon occurring which suggests a reason for this catastrophic divergence in performance. Quite simply we find that those who fail are doing a more difficult kind of mathematics compared to those who succeed. This difference arises out of the manner in which individuals cope with the progression from procedures of counting to the processes of arithmetic and the concept of number. Whilst the more able progress to use their knowledge in a flexible and powerful way, the less able seek security in counting procedures which work promisingly in simple tasks but fail to generalise when greater sophistication is required (Gray 1991).
