The overarching research work is based on two approaches: - Conceptual Analysis, Extraction and Linking - Experimentation with Product Libraries - Conceptual Analysis, Extraction and Linking: This aspect of the research has been achieved through the development of a conceptual framework for facilitating the understanding of the constituting components of BIM, Specifications and Cost Planning under investigation. The framework builds on theories spanning the constituent research themes and was used as a basis for justifying the elected approaches adopted throughout the research work. By means of tags and codes, a system for classifying building specification information has been developed as a differentiator between the chosen research approach and existing classification strategies in industry. Furthermore, syntactic links between extracted classes of specification information and cost planning have been established and will be adopted as a basis for authenticating the impact of specification information within BIM models. - Experimentation with Product Libraries Following the extraction and classification of BIM, Specifications and Cost Planning information, early experimentation on linking specifications to BIM models by means of a raas-based product library have been successful. A comparative analysis between a range of existing product libraries has also been realised. The outcomes have been amply documented in papers, all of which have received positive reviews. Ongoing experiments and analysis with the product library involve integrating the cost planning component for authenticating the completeness, relevance and impact of embedded specification within BIM models.

This article investigates the significance of internet communication technologies for mediating affect in ways that help promote feelings of well-being among recently arrived migrants from culturally and linguistically diverse communities (CALD) in Australia. It is based on a qualitative study that focuses on the internet's communicative capabilities for maintaining kinship ties in homeland countries, and for forging new connections in the host city of Brisbane during the early re-settlement period. Through the experience of ‘presence’ and affective communities, it emphasizes the ways in which visually mediated interaction helps to combat feelings of social isolation and loneliness. The study finds that internet use is creating new forms of sociality among migrants and plays a key role in the re-settlement period. It highlights the importance of publicly available computers and training for migrants.

We examine the association between institutional ownership, political connections, and analyst following in Malaysia from 1999 to 2009. Based on 940 firm-year observations, we document a positive relation between institutional ownership, particularly by Employees Provident Fund (EPF), and analyst following, thus supporting the governance role that institutional investors play in promoting corporate transparency. However, there is no evidence that political connections matter to analyst following. The monitoring role of institutional investors, including EPF, does not appear to be any different between politically connected and non-connected firms.

SIMON is a family of 10 lightweight block ciphers published by Beaulieu et al. from the United States National Security Agency (NSA). A cipher in this family with K -bit key and N -bit block is called SIMON N/K . We present several linear characteristics for reduced-round SIMON32/64 that can be used for a key-recovery attack and extend them further to attack other variants of SIMON. Moreover, we provide results of key recovery analysis using several impossible differential characteristics starting from 14 out of 32 rounds for SIMON32/64 to 22 out of 72 rounds for SIMON128/256. In some cases the presented observations do not directly yield an attack, but provide a basis for further analysis for the specific SIMON variant. Finally, we exploit a connection between linear and differential characteristics for SIMON to construct linear characteristics for different variants of reduced-round SIMON. Our attacks extend to all variants of SIMON covering more rounds compared to any known results using linear cryptanalysis. We present a key recovery attack against SIMON128/256 which covers 35 out of 72 rounds with data complexity 2123 . We have implemented our attacks for small scale variants of SIMON and our experiments confirm the theoretical bias presented in this work.

This paper traces aspects of the development of a ‘green’ criminology. It starts with personal reflections and then describes the emergence of explicit statements of a green criminological perspective. Initially these statements were independently voiced, in different parts of the world but they reflected shared concerns. These works have found unification as a ‘green’, ‘eco-global’ or ‘conservation’ criminology. The paper reviews the classifications available when talking about not only legally-defined crimes but also legally perpetrated harms, as well as typologies of such harms and crimes. It then looks at the integration of ‘green’ and ‘traditional’ criminological thinking before briefly exploring four dimensions of concern for today and the future.

Investigative journalists who join what theorist Manuel Castells describes as the ‘network society’ can locate potential news sources using various social media platforms and interview them using Web-based communication technologies. The potential for journalistic investigations involving multi-directional conversations with news sources across the globe is beginning to be explored. Potential news sources who are part of the network society have unprecedented access to specialist investigative reporters irrespective of their location and can speak to them more cost effectively than in the past. This paper explores how new journalism technologies are allowing journalists to call powerful individuals and institutions to account, irrespective of national borders; and how previously silenced individuals are being given a voice. To read an example of international investigative journalism facilitated by a combination of social media, Web-based communications, reporter collaboration and news outlet collaborations see http://www.theaustralian.com.au/news/features/churchs-wall-of-silence-on-sexual-abuse/story-e6frg6z6-1226639077238.

Description of Workshop/Poster Presentation This presentation will showcase CORE Connections – ‘Creating Opportunities for Resilience and Engagement’ – which is a whole-school approach to mental health promotion. While initially designed to prevent adolescent depression and substance abuse, current thinking suggests that competency enhancement (e.g., autonomy, competence, supportive networks) more widely improves students’ well-being, educational engagement, and learning outcomes. In the presentation, we will provide an overview of the CORE project, describe the CORE intervention, which is conceptualized as a dynamic and penetrating process of social practices, present some preliminary findings from the pilot phase of CORE, and conclude our presentation with an interactive section with the participants. This project will highlight a wellness focus that addresses social engagement within whole school cultures. Purpose of the Presentation Student mental and physical well-being has gained increasing attention. Our presentation will introduce the CORE project, which has a potential to decrease student depression, anxiety, and substance use, and to increase student self-esteem and learning outcomes. In this vein, our presentation will raise the public awareness of the salient role of social connection in student well-being. Specifically, a group of presenters will discuss the impact of social connection on students’ anxiety, mathematics achievement, and perceived racial discrimination. • We will present participants with an alternative way to conceptualize and approach mental health promotion within a school context. In contrast to prescribed programs that are commonly used in today’s schools, CORE is a whole-school approach that is flexibly integrated into all aspects of the classroom and school environment. Our aim is to illustrate the intervention principles of CORE while highlighting examples of mental health outcomes/transformation. • Underutilized in mental health promotion research, social network analysis provides critical information in understanding relationships between social cohesion (e.g., a student’s connectedness to others) and mental health outcomes. This session will showcase how focusing on and strengthening social connections in and out of school can contribute to student well-being, achievement, and mental health. Educational Objectives By the end of the presentation, participants will • obtain a general overview of the CORE program, • understand how psychological health and school performance relate to student well-being, • and understand how social connections in and out of school can contribute to student well-being. Interactive / Participatory Component We will invite audience members to discuss inhibitors and contributors to student well-being and the best ways for schools to help students feel safe, connected, and valued. Presentation Key Points • Overview of the CORE project • Theorization of social connection • Some empirical studies emerging from CORE • Presenter-audience interaction Evidence of Relevance and Utility to Participants Potential participants are adults with significant relationships with students, either as family members, community neighbors, educators, scholars, service providers, or policy makers. Our presentation will inspire these significant adults to construct a welcoming society to help improve student well-being.

The speed at which target pictures are named increases monotonically as a function of prior retrieval of other exemplars of the same semantic category and is unaffected by the number of intervening items. This cumulative semantic interference effect is generally attributed to three mechanisms: shared feature activation, priming and lexical-level selection. However, at least two additional mechanisms have been proposed: (1) a 'booster' to amplify lexical-level activation and (2) retrieval-induced forgetting (RIF). In a perfusion functional Magnetic Resonance Imaging (fMRI) experiment, we tested hypotheses concerning the involvement of all five mechanisms. Our results demonstrate that the cumulative interference effect is associated with perfusion signal changes in the left perirhinal and middle temporal cortices that increase monotonically according to the ordinal position of exemplars being named. The left inferior frontal gyrus (LIFG) also showed significant perfusion signal changes across ordinal presentations; however, these responses did not conform to a monotonically increasing function. None of the cerebral regions linked with RIF in prior neuroimaging and modelling studies showed significant effects. This might be due to methodological differences between the RIF paradigm and continuous naming as the latter does not involve practicing particular information. We interpret the results as indicating priming of shared features and lexical-level selection mechanisms contribute to the cumulative interference effect, while adding noise to a booster mechanism could account for the pattern of responses observed in the LIFG.

University strategic plans emphasise the essential nature of partnerships at national and international levels. Along with establishing collaborative research partnerships, providing professional development to key stakeholders is considered a crucial activity for making and sustaining partnerships. Utilising knowledge from professional development in Australian contexts can be managed creatively for making connections internationally. Indeed, knowledge transfer is a cornerstone for the globalisation of education and needs to occur as a multiplex dialogue between participating countries. This paper presents a qualitative study around the Mentoring for Effective Teaching (MET) program, its growth and development nationally (e.g., scope and impact) along with insights into making connections within the Asia-Pacific region. At a national level, we outline how to facilitate a program though relationship building and face-to-face implementation of professional learning. Internationally, we highlight how to mould and shape Australian professional learning for the Asia-Pacific region, particularly with regard to facilitating fluid interactions within environments outside of Australia. The contexts for the study include a university in Hong Kong and another university in the Philippines. In this presentation, examples will be provided from the MET program to demonstrate contextual differences and similarities for implementation in Australian and Asian contexts. For instance, determining strategies for mentoring pedagogical knowledge can elicit viewpoints that align between cultures (e.g., use of specific teaching and questioning strategies) and also present alternative ideas as a result of cultural differences. We have learnt about having a structured program that draws on the research yet has sufficient flexibility to cater for cultures and contexts. With openmindedness, facilitating professional learning can become a two-way knowledge transfer, where learnings from other cultures and contexts can be refined for advancing programs in Australia.

Widening participation or outreach agendas have been a major part of higher education policy since the early 2000s. These policies and programs seek to increase marginalised groups’ access to further study through activities, tutoring programs, workshops, and other provisions. Some programs openly state their intention to assist people from low socioeconomic backgrounds to become more civically engaged and socially mobile by improving their education, which creates an immediate link between education and social capital (see Morley 2012; Hillmert and Jacob 2010). Social capital refers to the ‘connections among individuals’ and the consequent value of the things they do together (Putnam 2000; Gauntlett 2011). Media and creative arts widening participation programs, arguably, are better equipped to build social capital than any other form of outreach, due to their relationship-building capacity (Gauntlett 2011; Kinder and Harland 2004). This article analyses Queensland University of Technology’s Creative Industries Widening Participation Program. It investigates social capital and its relationship with higher education in outreach initiatives in order to identify how media and creative arts widening participation programs have the capacity to influence the attitudes of low socioeconomic background students towards higher education.
