Space-crossing : community-based data forwarding in mobile social networks under the hybrid communication architecture

In this paper, we study two tightly coupled issues, space-crossing community detection and its influence on data forwarding in mobile social networks (MSNs). We propose a communication framework containing the hybrid underlying network with access point (AP) support for data forwarding and the base stations for managing most of control traffic. The concept of physical proximity community can be extended to be one across the geographical space, because APs can facilitate the communication among long-distance nodes. Space-crossing communities are obtained by merging some pairs of physical proximity communities. Based on the space-crossing community, we define two cases of node local activity and use them as the input of inner product similarity measurement. We design a novel data forwarding algorithm Social Attraction and Infrastructure Support (SAIS), which applies similarity attraction to route to neighbor more similar to destination, and infrastructure support phase to route the message to other APs within common connected components. We evaluate our SAIS algorithm on real-life datasets from MIT Reality Mining and University of Illinois Movement (UIM). Results show that space-crossing community plays a positive role in data forwarding in MSNs. Based on this new type of community, SAIS achieves a better performance than existing popular social community-based data forwarding algorithms in practice, including Simbet, Bubble Rap and Nguyen's Routing algorithms.

Personal, social and environmental determinants of educational inequalities in walking: a multilevel study

Objective: To investigate the contribution of personal, social and environmental factors to mediating socioeconomic (educational) inequalities in women’s leisure-time walking and walking for transport.
Methods: A community sample of 1282 women provided survey data on walking for leisure and transport; educational level; enjoyment of, and self-efficacy for, walking; physical activity barriers and intentions; social support for physical activity; sporting/recreational club membership; dog ownership; and perceived environmental aesthetics and safety. These data were linked with objective environmental data on the density of public open space and walking tracks in the women’s local neighbourhood, coastal proximity and street connectivity.
Results: Multilevel modelling showed that different personal, social and environmental factors were associated with walking for leisure and walking for transport. Variables from all three domains explained (mediated) educational inequalities in leisure-time walking, including neighbourhood walking tracks; coastal proximity; friends’ social support; dog ownership; self-efficacy, enjoyment and intentions. On the other hand, few of the variables examined explained educational variations in walking for transport, exceptions being neighbourhood, coastal proximity, street connectivity and social support from family.
Conclusions: Public health initiatives aimed at promoting, and reducing educational inequalities in, leisure-time walking should incorporate a focus on environmental strategies, such as advocating for neighbourhood walking tracks, as well as personal and social factors. Further investigation is required to better understand the pathways by which education might influence walking for transport.

Not just for romance: applications of speed dating in social work education

In this article we address how a contemporary adaptation of the 'speed dating' model was used for educational purposes with two cohorts of social work students. We outline the dimensions of 'speed dating' as a contemporary social phenomenon, then address how this model relates specifically to groupwork process, and can be used to facilitate social work student learning. The curriculum for two classroom group activities using the 'speed dating' model are outlined, the first to develop university level study skills, the second for debriefing field placement learning experiences. Finally we examine why the 'speed dating' metaphor was successful in provoking a playful yet constructively creative space for students to engage in groupwork process.

'Dig in' to social capital : community gardens as mechanisms for growing urban social connectedness

This article reports on research undertaken with members of a Melbourne urban community garden to explore the extent to which such a natural amenity provides opportunities for enhancing social capital. It is apparent even from this small qualitative study that membership of 'Dig In' community garden offers many benefits to its members. These benefits include increased social cohesion (the sharing of values enabling identification of common aims and the sharing of codes of behaviour governing relationships), social support (having people to turn to in times of crisis) and social connections (the development of social bonds and networks). However, the study indicates that, at least in the early stages of development, such benefits do not necessarily extend beyond the garden setting. This raises a question about the time required to develop high levels of social capital, and points to the need for further research into 'time' and 'space' aspects of community gardens.

Library learning space design : a good student fit

We are seeing a renewed interest nationally and internationally in the design and development of new learning environments. There is, at Deakin and more generally in the higher education sector, recognition that the students' experience of a flexible and supportive educational environment is central to excellent teaching and fosters student success. Recent Carrick Institute (now the Australian Learning and Teaching Council) grants have supported the need for a greater understanding of good practice, with workshops being held around the country.

The student experience is integral to planning the re-purposing of Library spaces at Deakin's two larger campuses, Waurn Ponds and Burwood. The physical spaces within the Library will be flexible and provide support for individual learning and study, group learning and discussion, with ubiquitous ICT access and assistance services readily accessible. The improvement to the amenities, including contemporary, wired casual spaces, will encourage students to come on to campus and stay, strengthening opportunities to build a learning community. This learning community can extend through opportunities for social networking to students studying online and off-campus.

Library services and spaces will align with the new pedagogical needs of the university, providing holistic support for students' flexible learning experiences.
"We know that space can have a significant impact on teaching and learning . . . What we know about how people learn has changed our ideas about learning space. There is value from bumping into someone and having a casual conversation. There is value from hands on, active learning as well as from discussion and reflection. There is value in being able to receive immediate support when needed and from being able to integrate multiple activities [and multiple information sources] to complete a project."

Globalizing time and space : temporal and spatial considerations in discourses of globalization

Globalization discourse is concerned with the effects of spatial change—changes in the shape, scale and extensity or social processes— and the effects of temporal change—particularly changes to, or away from, modernity. By drawing together both axes of change, globalization discourse suggests a way of navigating this tension. However, it is argued here that most globalization theories accord primacy to one of these axes, which results in them being conflated. As a result, globalization theories are often presented in highly systemic terms and downplay the diversity of social processes.

Social justice in education in 'new times'

This thesis considers social justice in education in ‘new times’. To facilitate the investigation a number of research questions were pursued. These questions were: • What is meant by the label ‘social justice’? • How is social justice to be understood in contemporary terms? • Are there tensions between traditional and contemporary views of social justice? • How effective are policy developments in delivering social justice via education? • What difference do such policies make at the local level? To answer these questions a critical case analysis of a country community and one of its primary schools was carried out. Data were gathered using a variety of methods. As a researcher who was also a teacher in the school I kept a personal professional journal during 1993 and 1994. During this period I was the teacher in the school with responsibility for curriculum development related to issues of social justice. In 1994 I conducted interviews with twenty students, parents and teachers at the school in relation to social justice issues. I also interviewed the CEO of the town’s Council. A number of relevant Federal and State Government and school policy documents were consulted and an archival search of the local newspaper from 1956 to 1994 was undertaken. Statistical information from the Australian Bureau of Statistics as well as from school records was used. A number of local history books were consulted as well as the minutes of relevant school committee meetings. Contemporary social theory, more specifically the work of Anthony Giddens, provided the major methodological tool. Giddens structuration theory was selected as it provided a way of interpreting society from both macro and micro perspectives, it provided a way of studying the interconnectedness of the individual and society. In addition to this, a metaphor was used as a way of developing an understanding of the data. The river was chosen as the metaphor as it has significance to the case study community and it also provides a way of understanding interconnectedness. At an interpretive level, both social theory and moral philosophy were drawn on, including the work of Geoffrey Sharp, Anthony Giddens and Alisdair MacIntyre. A review of selected literature indicated three main areas of concern in relation to this thesis. We live in a time of constant and ongoing change, understanding how this change impacts on the lives of individuals and society is important. Such an understanding relates directly to issues of ontology. In addition it was necessary to consider schools in these ‘new times’. The literature revealed that the changes occurring in the wider society were related to the changes currently being seen in schools. Specifically this related to the increasing emphasis on economics and on individualism, emphases also reflected in the findings of this thesis. Finally the literature related to social justice was discussed, the focus here was on distributive theories of justice and the way these are reflected in programs such as the DSP. The data, as expressed in the metaphor of the flowing river, revealed dominant and marginal currents in social justice in education in ‘new times’. The dominant social group are the intellectually trained and the dominant issues were related to technology, globalisation and economic and bureaucratic rationalism. In the marginal currents we find the under-employed and the unemployed and marginal issues relating to housing, the black economy, poverty and the survival of rural communities. The data also revealed a marginal tributary running into the river. This tributary shows that social cohesion is still a part of life in ‘new times’, albeit a marginalised part. The dominant and marginal currents in social justice in ‘new times’ reveal changes at a deep cultural level. Social justice in ‘new times’ is set within the limits provided by economic rationalism. Such a position is closely linked to the rise of liberal democracy as a political ideology. A rise which has been on a global scale. This valorizes the individual as compared with the group, and the family as compared to the social whole, within the context of expanded economic groupings and markets. Such an ideological position sees the role of the state as providing the ‘legitimising muscle’ to advance the cause of individuals and their families as compared to larger social groupings. These perceptions were applied in Australia, even under a Labor Government. In this sense social justice policies in ‘new times’ are ideological, they act as a political lever to legitimate economic restructuring. They are policies designed to carry disparate groups forward and together on a common wave of economic reform. They are used to ‘sell’ economic reform as being ‘good’ for all of society. Against the backdrop of economic rationalism and liberal democratic ideals there emerges a language geared to the production of an economically viable self, self image, self identity, self esteem and self confidence. As a result, the sense of identity as ‘social’ is lost from view. This thesis argues that what is needed is a new way of looking at social justice in education. A way that reaches beyond the solutions forwarded by the political Left and the Right. It is about the development of an understanding of the way in which an assimilation of the hyper individual and the social group can result in the emergence of the socially responsible individual. This is a cultural shift that sees the individual/society dualism presented in a new way. The categories enter into a new relationship where the balance shifts away from the individual towards society. A shift to a culture where the individual’s rights and responsibilities are respected within a social whole. Such a cultural shift would result in a curriculum which would build social identity, promoted socially responsible independent thought and make space for creativity and the aesthetic. A ‘curriculum for social responsibility’ would be a socially just curriculum.

Envisioning Indochina : the spatial and social ordering and imagining of a French colony

The emergence of Indochina in the French imagination was articulated in both representational and institutional modes. Representation involves the transmission of colonial ideals through more obtuse means; that is, through literary texts, travelogues, exhibitions, film and advertising. However, these textual sites feed from and invest in a material situation, which was the institutional arm of colonialism. Indochina was institutionally articulated in cartographic maps and surveys, in the new social spaces of cities and towns, in architectural and technological forms, through social technologies of discipline and welfare and in cultural and religious organisations. The aim of this thesis is to analyse, across a number of textual sites, the representation and institutionalisation of Otherness through the politics of space in the French colony of Indochina, Indochine in this sense becomes a spatial discourse. The French constructed a mental and physical space for Indochina by blanketing and suffocating the original cultural landscape, which in fact had to be ignored for this process to occur. What actually became manifest as a result of this projection stemmed from the French imagination. Just as the French manipulated space, language also underwent the same process of reduction. The Vietnamese script was latinised to make it more 'useable' and ‘accessible’. Through christening the union of Indochina; initiating a comprehensive writing reform; and renaming the streets in the colonial cities, the French used language us another tool for 'making transparent'. Furthermore, the colonial powers established a communication and transport network throughout the colony in an attempt to materialise their fictive (artificial) vision of a unified French Indochinese space. The accessibility and design of these different modes of transport reflected the gendered, racial and class divisions inherent in the colonial establishment. At the heart of representing and institutionalising Indochina was the desire to control and contain. This characterised French imperial ordering of space in the city and the rural areas. In rural areas land was divided into small parcels and alienated to individuals or worked into precise grids for the rubber plantation. In urban centres the native quarter was clearly demarcated from the European quarter which functioned as its modern, progressive Other. The rationale behind this segregation was premised on European, nineteenth century discourses of race, class, gender and hygiene. Influenced by Darwinian and neo-Lamarkian theories of race, this biological discourse identified the 'working class', 'women' and 'the native' as not only biologically but also culturally inferior. They were perceived as a potential, degenerative threat to the biological, cultural and industrial development of the nation. In the colonial context, space was thus ordered and domesticated to control the native population. Coextensively, the literature which springs from such a structure will be tainted by the same ideas, and thus the spaces it formulates within the readers mind feed on and reinforce this foundation. Examples of gender and indigenous narratives which contest this imaginative, transparent topography are analysed throughout this thesis. They provide instances of struggle and resistance which undermine the ideal/stereotypical level of architectural and planned space and delineate an alternative insight into colonial spatial and social relations. The fictional accounts of European women and indigenous writers both challenge and reaffirm the fixity of some of these idealised colonial boundaries. In various literary, historical, political, architectural and cinematic discourses Indochina has been und continues to be depicted as a modern city and exotic Utopia. Informed by the mood of nostalgia, exotic images of Indochina have resurfaced in contemporary French culture. France's continued desire to create, control and maintain an Indochinese space in the French public imagination reinforces the multi-layered, interconnected and persistent nature of colonial discourse.

Women's silence : in the space of words and images

My thesis is made up of words and images. This study investigates the way in which silence operates productively within and between the two modes of communication. I suggest that in the process of changing words into images or scripto-visual art-practice, the silence in women's lives can be articulated. I argue that women draw on the generative qualities of silence to create forms of speech that override the cultural constructions of gender which have placed them within the space of ‘mute’ silence. To gain an historical perspective of this practice by women, I consider the lives of medieval nuns within religious enclosure and their work with words and images in the illuminated manuscript. I make a comparative study of original illuminated manuscripts, focussing mainly on visual language and locating aspects of the work closest to my own art-practice: the visual treatment of the space and inter-textual components of the page or folio. This project does not include an examination of miniatures or historiated initials. Rather, its aim is to identify and compare the use of other aesthetic devices available to the medieval scribe/artist through which they might have interacted with the text. I suggest links between verbal and visual performances of language and the repetition, or copying of texts by medieval nuns, as a means of female embodiment of words and their spaces. From the outcomes of my studio investigations and my consideration of other contemporary feminist art practices, I demonstrate how women artists may ‘re-write’ the text and ‘speak’ their silence through visual language and the acts of writing, drawing and painting the words of others. Through my engagement with feminist critical theory, the work of medieval scholars, original illuminated manuscripts and my studio research, I propose that scripto-visual practice remains particularly significant for women despite the differences between the medieval period and our own. As a generative practice, it negotiates some of the societal constraints on women's speech and visibility, because its language is ‘silent and disembodied’ from the image of woman constructed by male discourse. It is a form of speech that acknowledges as it defies the social and cultural conditions that shaped its necessity, articulating an alternative voice of women in the space of words and images.

Professional development and Web 2.0, can the space make a difference?

A professional development (Summer School) with over two hundred teachers of English participating in the activity for over six months, was supported by an online social software website. The employment of Web 2.0 technologies to facilitate the delivery of the summer school was reasonably successful, but other benefits were realised. This poster presentation will show how scaffolded learning along with new experiences and knowledge, can potentially have added long-term value when sustained in an authentic, supportive learning environment.

Promoting social support and social networks among Irish pensioners in South London, UK

This paper explores the activities of an Irish-led voluntary sector project that sought to minimise social isolation and build social networks among Irish elderly people living in a socio-economically deprived borough in South London, UK. The study from which this paper is drawn aimed to explore the nature and extent of unmet mental health needs among Irish pensioners. Using a naturalistic and exploratory design, data were collected through 19 semi-structured interviews, observation of project activities and analysis of members' case files. The paper presents findings in relation to the significant themes that emerged from the data analysis, which used a grounded theory approach. It discusses the social support systems within the project and examines the ways in which they maintained the mental wellbeing of the projects' members and interconnected with other areas of the project's activities. The study's findings demonstrated that the project provided space for social interaction among otherwise isolated Irish pensioners, many of whom experienced multiple morbidity. The project worked successfully to overcome the sense of stigma that prevented many of its members accessing statutory services; it also identified needs among carers. There was an Irish cultural ambience at the project centre, which generated a sense of belonging among members, and assisted in the development of social networks. The project initiated other forms of social support through the use of volunteers and developed befriending and telephone support services. The project developed partnership working with other agencies, particularly community mental health services, in order to provide support to elderly people who might otherwise have been institutionalised. The project engaged with the cultural norms of this marginalised white minority ethnic community to promote both social interaction and social networks. It offered a model of good practice for agencies working with isolated elderly members of minority ethnic communities.

Trapped in white space : the allegations and denials of organ trafficking

Allegations of body parts trafficking implicating the West have been surfacing persistently in the media of many non Western countries for almost 20 years. Western media has responded to the allegations with denials and denunciations. This thesis considers the competing accounts and places them in a framework for analysis.

Representação espacial na cognição ambiental urbana : aspectos de uso do solo e presença social

In the present paper different representations of urban character that influence environmental cognition are tested. Two main features involved in urban identity are the functional and social aspects of urban environment. Land use of lots is aggregated into different intensity measures that explore functional characterization of urban spaces. Social presence related to residential use and movement in urban space are also evaluated by intensity and social-economic characteristics. All selected attributes come from normal governmental data bases. Thus, one of the challenges is to transpose/interchange data from different scale units into a unique spatial representation unit, creating a common spatial base in a GIS environment.

Future Asian space : projecting the urban space of new East Asia

The idea of "Asian space" is undergoing a transformation as a result of rapid technological, economic, social and cultural changes. Following the shift to a global economy and an urban population explosion, Asian cities have been presented as a mainstay of progress, national pride, identity, and positioning on the global stage. The extraordinary pace and intensity of the changes have created a situation unique in the history of urban development. Despite the immense diversity of Asian countries, "Asia-ness" is often treated as a distinctive quality that has emerged from unique recent circumstances affecting Asian urbanizations as a whole. In Future Asian Space, 15 authors explore broad concepts relating to the creation and re-creation of "Asian space" and contemporary Asian identity, and their examination of different sites and research approaches highlights the difficulty of pinpointing what Asia-ness is, or might become. Appropriate design and planning of cities is a critical element in building a sustainable future and coping with environmental, social and cultural problems. Future Asian Space is designed to stimulate interest and engagement in discussions of the Asian city, and its trajectories in architecture and urbanism. The authors' conclusions are important for academics, theorists and practitioners, but they will also intrigue anyone interested in the future of cities and urban life in Asia.

Computable social patterns from sparse sensor data

We present a computational framework to automatically discover high-order temporal social patterns from very noisy and sparse location data. We introduce the concept of social footprint and present a method to construct a codebook, enabling the transformation of raw sensor data into a collection of social pages. Each page captures social activities of a user over regular time period, and represented as a sequence of encoded footprints. Computable patterns are then defined as repeated structures found in these sequences. To do so, we appeal to modeling tools in document analysis and propose a Latent Social theme Dirichlet Allocation (LSDA) model - a version of the Ngram topic model in [6] with extra modeling of personal context. This model can be viewed as a Bayesian clustering method, jointly discovering temporal collocation of footprints and exploiting statistical strength across social pages, to automatically discovery high-order patterns. Alternatively, it can be viewed as a dimensionality reduction method where the reduced latent space can be interpreted as the hidden social 'theme' - a more abstract perception of user's daily activities. Applying this framework to a real-world noisy dataset collected over 1.5 years, we show that many useful and interesting patterns can be computed. Interpretable social themes can also be deduced from the discovered patterns.
