A framework for social networked architectural education

Students engage in Social Networks (SN) as a form of interaction with friends and tutors, as news or learning resource, to make their voices heard or to listen to other views and many more. Online SN work in close association with offline SN to form a blended social environment that greatly enables and enhances students' learning. Some Schools of Architecture have struggled or failed to engage in the potential of SN or their respective University's online Learning Management Systems (LMS). Despite efforts to facilitate blended learning environments or to engage students in problem-based learning activities architectural education often fails to tap into the rich resources that online social learning environments offers through their collective and social intelligence of its users. This paper proposes a framework for SN architectural education that provides opportunities for linking the academic LMS with private or professional SN such that it enhances the learning experience and deepens the knowledge of the students. The paper proposes ways of utilising SN supported learning environments in other areas of the curriculum and concludes with directions of how this framework can be employed in professional settings.

Exploring second life as a learning environment for computer programming

Computer programming can be challenging for beginners because of the need to understand abstract programming concepts. In this paper, we study the use of the Second Life (SL) virtual world for learning computer programming concepts. We conduct an empirical study for learning computer programming in SL by addressing affordances of SL for experiential problem-based learning pedagogies. We present preliminary findings, the promises and the limitations of Second Life as an environment for learning computer programming.

Muslim young people online: “Acts of citizenship” in socially networked spaces

This paper reviews the current literature regarding Muslim young people’s online social networking and participatory practices with the aim of examining whether these practices open up new spaces of civic engagement and political par-ticipation. The paper focuses on the experiences of young Muslims living in western societies, where, since September 11, the ability to assert claims as citizens in the public arena has diminished. The paper draws upon Isin & Nielsen’s (2008) “acts of citizenship” to define the online practices of many Muslim youth, for whom the internet provides a space where new performances of citizenship are enacted outside of formal citizenship rights and spaces of participa-tion. These “acts" are evaluated in light of theories which articulate the changing nature of publics and the public sphere in a digital era. The paper will use this conceptual framework in conjunction with the literature review to ex-plore whether virtual, online spaces offer young Muslims an opportunity to create a more inclusive discursive space to interact with co-citizens, engage with social and political issues and assert their citizen rights than is otherwise afforded by formal political structures; a need highlighted by policies which target minority Muslim young people for greater civ-ic participation but which do not reflect the interests and values of Muslim young people.

Placing sensors for area coverage in a complex environment by a team of robots

Existing solutions to carrier-based sensor placement by a single robot in a bounded unknown Region of Interest (ROI) do not guarantee full area coverage or termination. We propose a novel localized algorithm, named Back-Tracking Deployment (BTD). To construct a full coverage solution over the ROI, mobile robots (carriers) carry static sensors as payloads and drop them at the visited empty vertices of a virtual square, triangular, or hexagonal grid. A single robot will move in a predefined order of directional preference until a dead end is reached. Then it back-tracks to the nearest sensor adjacent to an empty vertex (an "entrance" to an unexplored/uncovered area) and resumes regular forward movement and sensor dropping from there. To save movement steps, the back-tracking is carried out along a locally identified shortcut. We extend the algorithm to support multiple robots that move independently and asynchronously. Once a robot reaches a dead end, it will back-track, giving preference to its own path. Otherwise, it will take over the back-track path of another robot by consulting with neighboring sensors. We prove that BTD terminates within finite time and produces full coverage when no (sensor or robot) failures occur. We also describe an approach to tolerate failures and an approach to balance workload among robots. We then evaluate BTD in comparison with the only competing algorithms SLD [Chang et al. 2009a] and LRV [Batalin and Sukhatme 2004] through simulation. In a specific failure-free scenario, SLD covers only 40-50% of the ROI, whereas BTD covers it in full. BTD involves significantly (80%) less robot moves and messages than LRV.

Linking and sharing data in the humanities and creative arts: building the HuNI Virtual Laboratory

The Humanities Networked Infrastructure (HuNI) is one of the national Virtual Laboratories that are being developed as part of the Australian government's National e-Research Collaboration Tools and Resources (NeCTAR) programme. This paper examines the methodologies and technical architecture being deployed by HuNI to link and share Australian data in the humanities and creative arts.

Touching space: Using motion capture and stereo projection to create a "virtual haptics" of dance

This paper describes the work of a group of artists in Australia who used real-time motion capture and 3D stereo projection to create a large-scale performance environment in which dancers seemed to "touch" the volume. This project re-versions Suzanne Langer's 1950s philosophy of dance as "virtual force" to realize the idea of a "virtual haptics" of dance that extends the dancer's physical agency literally across and through the surrounding spatial volume. The project presents a vision of interactive dance performance that "touches" space by visualizing kinematics as intentionality and agency. In doing so, we suggest the possibility of new kinds of human-computer interfaces that emphasize touch as embodied, nuanced agency that is mediated by the subtle qualities of whole-body movement, in addition to more goal-oriented, task-based gestures such as pointing or clicking. © 2010.

Keyboard control method for virtual reality micro-robotic cell injection training

The rapid development of virtual reality offers significant potential for skills training applications. Our ongoing work proposes virtual reality operator training for the micro-robotic cell injection procedure. The interface between the operator and the system can be achieved in many different ways. The computer keyboard is ubiquitous in its use for everyday computing applications and also commonly utilized in virtual reality systems. Based on the premise that most people have experience in using a computer keyboard, as opposed to more sophisticated input devices, this paper considers the feasibility of using a keyboard to control the micro-robot for cell injection. In this study, thirteen participants underwent the experimental evaluation. The participants were asked to perform three simulated trial sessions in a virtual micro-robotic cell injection environment. Each session consisted of ten cell injection trials and relevant data for each trial were recorded and analyzed. Results showed participants' performance improvement after the three sessions. It was also observed that participants intuitively controlled multiple axes of the micro-robot simultaneously despite the absence of instruction on how to do so. This continued throughout the experiments and suggests skills transfer from other keyboard based interactions. Based on the results provided, it is suggested that keyboard control is a feasible, simple and low-cost control method for the virtual micro-robot.

Teachers' perceptions of virtual worlds as a medium for social inclusion for adults with intellectual disability

PURPOSE: The aim of this research was to explore educators' perceptions of a virtual world Second Life TM as an environment for social interaction and social inclusion for the Norwegian adult students with intellectual disability that they supported.

METHOD: Five educators who supported a total of 10 adult students with intellectual disability in computer classes in community Adult Education Centres participated in individual in-depth interviews. The interviews were transcribed verbatim and analysed using a content analysis.

RESULTS: Participants were positive about Second Life although they did not perceive that it offered a successful context for social interaction or inclusion. They identified a number of benefits to using a virtual world and for students participating in virtual world research. Barriers identified included language, literacy, and technology issues along with the complexity of participating independently in a virtual world.

CONCLUSIONS: Some people with intellectual disability can use virtual worlds but the skills required need additional research. Virtual worlds may provide a stimulating, safe, and exciting context for a range of activities but the level of support required by many people is high and consequently expensive.

Blended learning and art education: student participation in a collaborative, authentic assessment project

This paper reports on higher education student engagement with blended learning experiences incorporating located (on campus), cloud based (online e-learning ) and graphically built, socially networked 3D multi user virtual environments (MUVES). Immersion in this environment enabled collaboration between two groups of students enrolled in separate undergraduate art education and public relations units, to identify, develop and participate in an integrated, authentic assessment project. It is contended that immersive blended learning experiences support creative problem solving and encourages synchronous and asynchronous student participation in authentic problem solving and collaborative practice. Interacting with co-learners, students gain knowledge and skills through situated learning, defined as the application of knowledge, learned in one setting and transferred to another and where immersion in a virtual learning experience leads to higher level engagement on the transfer task in a real world setting. In this project, collaborative blended learning involved the creation of a collection of digital artworks by art education students using computer software located in a real world environment. These artworks were curated and exhibited by the students in a virtual gallery they designed and built on Deakin Arts Education island in Second Life. For public relations students, the virtual art exhibition was the focus of a virtual campaign, designed, researched and developed by them to promote the Deakin Virtual Art Gallery on Deakin island in Second Life. The final promotion for the Virtual Gallery was presented by the students at a symposium in both real world and virtual world environments.

Responding to the widening participation agenda through improved access to and within 3D virtual learning environments

The Australian Government's widening participation agenda - also referred to as the social inclusion agenda - considers equity through the triple focus of access, participation and outcomes. These foci are catalysts for re-examining teaching and learning approaches in formal education. This article considers this national refocus and the possibilities for addressing access and equity issues through and within threedimensional virtual learning environments (3DVLEs). The findings of an Australian Learning and Teaching Council (ALTC)-funded project that investigated the potential of an accessible 3DVLE for increasing access and participation of students with disabilities are reported, and strategies for improving outcomes (i.e. retention, success and completion) proposed. The article also highlights some of the remaining challenges with regard to the goal of improving outcomes for under-represented learner groups. The final section of the article identifies areas for further research.

Interference-aware coordinated power allocation in autonomous Wi-Fi environment

Self-managed access points (APs) with growing intelligence can optimize their own performances but pose potential negative impacts on others without energy ef ciency. In this paper, we focus on modeling the coordinated interaction among interest-independent and self-con gured APs, and conduct the power allocation case study in the autonomous Wi-Fi scenario. Speci cally, we build a `coordination Wi-Fi platform (CWP), a public platform for APs interacting with each other. OpenWrt-based APs in the physical world are mapped to virtual agents (VAs) in CWP, which communicate with each other through a standard request-reply process de ned as AP talk protocol (ATP).With ATP, an active interference measurement methodology is proposed re ecting both in-range interference and hidden terminal interference, and the Nash bargaining-based power control is further formulated for interference reductions. CWP is deployed in a real of ce environment, where coordination interactions between VAs can bring a maximum 40-Mb/s throughput improvement with the Nash bargaining-based power control in the multi-AP experiments.

Informal networked learning as teamwork in design studio Cmyview: using mobile digital technologies to connect with student's everyday experiences

CmyView is a research project that investigates how mobile technologies have the potential to facilitate new ways to share, experience and understand the connections that people have with places. The aim of the project is to theorise and develop a tool and a methodology that addresses the reception of architecture and the built environment using mobile digital technologies that harness ubiquitous everyday practices, such as photography and walking. While CmyView is primarily focused on evidencing the reception of places, this chapter argues that these activities can also make a contribution to the core pedagogy of architectural education, the design studio. This chapter presents findings of an initial pilot study with four students at an Australian university that demonstrates how CmyView offers a valuable contribution to the educational experience in the design studio.

Assuring virtual network reliability and resilience

A framework developed that uses reliability block diagrams and continuous-time Markov chains to model and analyse the reliability and availability of a Virtual Network Environment (VNE). In addition, to minimize the unpredicted failures and reduce the impact of failure on a virtual network, a dynamic solution proposed for detecting a failure before it occurs in the VNE. Moreover, to predict failure and establish a tolerable maintenance plan before failure occurs in the VNE, a failure prediction method for VNE can be used to minimise the unpredicted failures, reduce backup redundancy and maximise system performance.
