Distributed leadership and professional learning communities

This paper focuses on understanding distributed leadership and professional learning communities (PLCs). Through an Australian Government grant, the Teacher Education Done Differently (TEDD) project, data were analysed from 25 school executives about distributed leadership as a potential for influencing educational change through forums such as PLCs. Findings will be discussed in relation to: (1) Understanding the nature of a PLC, (2) Leadership within PLCs, (3) Advancing PLCs, and (4) PLCs as forums for capacity building a profession. A cyclic model for facilitating PLCs is presented, where information such as issues and problems are brought to the collective, discussed and analysed openly to provide further feedback. There are implications for leaders to up-skill staff on distributed leadership practices and further research required to determine which practices facilitate successful PLCs.

A formative evaluation of the Stronger Smarter Learning Communities Project. 2011 report.

This report is a formative evaluation of the operations of the DEEWR funded Stronger Smarter Learning Community (SSLC) project from September 2009 to July 2011. It is undertaken by an independent team of researchers from Queensland University of Technology, the University of Newcastle and Harvard University. It reports on findings from: documentary analysis; qualitative case studies of SSLC Hub schools; descriptive, multivariate and multilevel analysis of survey data from school leaders and teachers from SSLC Hub and Affiliate schools and from a control group of non-SSLC schools; and multilevel analysis of school-level data on SSLC Hubs, Affiliates and ACARA like-schools. Key findings from this work are that: • SSLC school leaders and teachers are reporting progress in changing school ethos around issues of: recognition of Indigenous identity, Indigenous leadership, innovative approaches to staffing and school models, Indigenous community engagement and high expectations leadership; • Many Stronger Smarter messages are reportedly having better uptake in schools with high percentages of Indigenous students; • There are no major or consistent patterns of differences between SSLC and non-SSLC schools in teacher and school leader self-reports of curriculum and pedagogy practices; and • There is no evidence to date that SSLC Hubs and Affiliates have increased attendance or increased achievement gains compared to ACARA like-schools. Twenty-one months is relatively early in this school reform project. Hence the major focus of subsequent reports will be on the documentation of comparative longitudinal gains in achievement tests and improved attendance. The 2011 and 2012 research also will model the relationships between change in school ethos/climate, changed Indigenous community relations, improved curriculum/pedagogy, and gains in Indigenous student achievement, attendance and outcomes. The key challenge for SSLC and the Stronger Smarter approach will be whether it can systematically generate change and reform in curriculum and pedagogy practices that can be empirically linked to improved student outcomes.

New percentage body fat prediction equations for Japanese females

Anthropometry is a simple and cost-efficient method for the assessment of body composition. However prediction equations to estimate body composition using anthropometry should be ‘population-specific’. Most popular body composition prediction equations for Japanese females were proposed more than 40 years ago and there is some concern regarding their usefulness in Japanese females living today. The aim of this study was to compare percentage body fat (%BF) estimated from anthropometry and dual energy x-ray absorptiometry (DXA) to examine the applicability of commonly used prediction equations in young Japanese females. Body composition of 139 Japanese females aged between 18 and 27 years of age (BMI range: 15.1–29.1 kg/m2) was measured using whole-body DXA (Lunar DPX-LIQ) scans. From anthropometric measurements %BF was estimated using four equations developed from Japanese females. The results showed that the traditionally employed prediction equations for anthropometry significantly (p<0.01) underestimate %BF of young Japanese females and therefore are not valid for the precise estimation of body composition. New %BF prediction equations were proposed from the DXA and anthropometry results. Application of the proposed equations may assist in more accurate assessment of body fatness in Japanese females living today.

Gatekeeping, gatewatching, real-time feedback : new challenges for Journalism

How bloggers and other independent online commentators criticise, correct, and otherwise challenge conventional journalism has been known for years, but has yet to be fully accepted by journalists; hostilities between the media establishment and the new generation of citizen journalists continue to flare up from time to time. The old gatekeeping monopoly of the mass media has been challenged by the new practice of gatewatching: by individual bloggers and by communities of commentators which may not report the news first-hand, but curate and evaluate the news and other information provided by official sources, and thus provide an important service. And this now takes place ever more rapidly, almost in real time: using the latest social networks, which disseminate, share, comment, question, and debunk news reports within minutes, and using additional platforms that enable fast and effective ad hoc collaboration between users. When hundreds of volunteers can prove within a few days that a German minister has been guilty of serious plagiarism, when the world first learns of earthquakes and tsunamis via Twitter – how does journalism manage to keep up?

Using the web to look for work: Implications for online job seeking and recruiting

Purpose - The web is now a significant component of the recruitment and job search process. However, very little is known about how companies and job seekers use the web, and the ultimate effectiveness of this process. The specific research questions guiding this study are: how do people search for job-related information on the web? How effective are these searches? And how likely are job seekers to find an appropriate job posting or application? Design/methodology/approach - The data used to examine these questions come from job seekers submitting job-related queries to a major web search engine at three points in time over a five-year period. Findings - Results indicate that individuals seeking job information generally submit only one query with several terms and over 45 percent of job-seeking queries contain a specific location reference. Of the documents retrieved, findings suggest that only 52 percent are relevant and only 40 percent of job-specific searches retrieve job postings. Research limitations/implications - This study provides an important contribution to web research and online recruiting literature. The data come from actual web searches, providing a realistic glimpse into how job seekers are actually using the web. Practical implications - The results of this research can assist organizations in seeking to use the web as part of their recruiting efforts, in designing corporate recruiting web sites, and in developing web systems to support job seeking and recruiting. Originality/value - This research is one of the first studies to investigate job searching on the web using longitudinal real world data. © Emerald Group Publishing Limited.

A recommendation method for online dating networks based on social relations and demographic information

A new relationship type of social networks - online dating - are gaining popularity. With a large member base, users of a dating network are overloaded with choices about their ideal partners. Recommendation methods can be utilized to overcome this problem. However, traditional recommendation methods do not work effectively for online dating networks where the dataset is sparse and large, and a two-way matching is required. This paper applies social networking concepts to solve the problem of developing a recommendation method for online dating networks. We propose a method by using clustering, SimRank and adapted SimRank algorithms to recommend matching candidates. Empirical results show that the proposed method can achieve nearly double the performance of the traditional collaborative filtering and common neighbor methods of recommendation.

Convenience, loyal, and customising users : a survey of the behaviours and intentions of young online news users in Australia

The implications of the shift to online news consumption for journalism cultures and practices have attracted considerable scholarly attention and public debate. Less well considered are the implications of online news consumption for and by young people. This paper reports on research into the behaviours and intentions of online news consumers, 18-30 years of age, to propose three distinctive types of user (convenience, loyal and customising). Also opened up for discussion are questions about the strategic value to commercial news organisations of audience-centred empirical research that seeks to respond the crisis of professional journalism.

Communities of practice : building organisational capability through an undergraduate assurance of learning program

This study explores academic perceptions of organizational capability and culture following a project to develop a quality assurance of learning program in a business school. In the project a community of practice structure was established to include academics in the development of an embedded, direct assurance of learning program affecting more than 5000 undergraduate students and 250 academics from nine different disciplines across four discipline based departments. The primary outcome from the newly developed and implemented assurance of learning program was the five year accreditation of the business school’s programs by two international accrediting bodies, EQUIS and AACSB. This study explores a different outcome, namely perceptions of organizational culture and individual capabilities as academics worked together in teaching teams and communities. This study uses a survey and interviews with academics involved, through a retrospective panel design consisting of an experimental group and a control group. Results offer insights into communities of practice as a means of encouraging new individual and organizational capability and strategic culture adaptation.

Sacred cows and crashing boars : ethno-religious minorities and the politics of online representation in Malaysia

Starting with the incident now known as the Cow’s Head Protest, this article traces and unpacks the events, techniques, and conditions surrounding the representation of ethno-religious minorities in Malaysia. The author suggests that the Malaysian Indians’ struggle to correct the dominant reading of their community as an impoverished and humbled underclass is a disruption of the dominant cultural order in Malaysia. It is also among the key events to have has set in motion a set of dynamics—the visual turn—introduced by new media into the politics of ethno-communal representation in Malaysia. Believing that this situation requires urgent examination the author attempts to outline the problematics of the task.

Attraction and retention in rural and remote communities

Attracting and retaining a skilled labour force is a critical yet complex issue for rural and remote communities. This article reports the findings of a study investigating the current approaches to recruitment and retention in two separate Australian regions. Building on previously developed models, the research analyses the roles employers and the wider communities are playing, or potentially could play, in addressing issues that influence labour shortages. The findings of the research highlight the complexities of employee attraction and retention and emphasise the need for communities and businesses to work together to overcome labour shortages in rural and remote locations.

Cognitive engagement and questioning online

This chapter discusses a range of issues associated with supporting inquiry and deep reasoning while utilising information and communications technology (ICT). The role of questioning in critical thinking and reflection is considered in the context of scaffolding and new opportunities for ICT-enabled scaffolding identified. In particular, why-questioning provides a key point of focus and is presented as an important consideration in the design of systems that not only require cognitive engagement but aim to nurture it. Advances in automated question generation within intelligent tutoring systems are shown to hold promise for both teaching and learning in a range of other applications. While shortening attention spans appear to be a hazard of engaging with digital media cognitive engagement is presented as something with broader scope than attention span and is best conceived of as a crucible within which a rich mix of cognitive activities take place and from which new knowledge is created.

Online dating and intimacy in a mobile world

The nature and possibilities for intimacy between adults are changing in the mobile era. Bauman (2003) has decreed this the era of ‘liquid love’, in which intimacy is commodified and committed relationships have been replaced by fleeting connections. In contrast, Giddens (1991; 1993) suggests that the reordering of everyday life in late-stage modernity has given rise to the possibility of a democratization of interpersonal interaction, characterized by reflexive ‘pure relationships’. The purpose of this paper is to consider theoretical debates about intimacy in the mobile era with regard to the contemporary practice of online dating. Drawing on our qualitative research with 23 online daters in Australia, we argue that, while the architecture of online dating is consistent with liquid love, many online daters simultaneously desire the possibilities for consumption afforded by liquid love, while aspiring to the formation of pure relationships and/or more practical forms of caring. This creates tensions in people’s experiences of this form of purposeful meeting, which are reflective of the conflicting socialities of intimacy available to us in the mobile era. At the same time, our research revealed disruptions to these tensions, by illuminating experiences where the consumerist orientation of online dating stimulated processes of reflexive self-discovery amongst our participants.

Integrating collaborative filtering and search-based techniques for personalized online product recommendation

The existing Collaborative Filtering (CF) technique that has been widely applied by e-commerce sites requires a large amount of ratings data to make meaningful recommendations. It is not directly applicable for recommending products that are not frequently purchased by users, such as cars and houses, as it is difficult to collect rating data for such products from the users. Many of the e-commerce sites for infrequently purchased products are still using basic search-based techniques whereby the products that match with the attributes given in the target user's query are retrieved and recommended to the user. However, search-based recommenders cannot provide personalized recommendations. For different users, the recommendations will be the same if they provide the same query regardless of any difference in their online navigation behaviour. This paper proposes to integrate collaborative filtering and search-based techniques to provide personalized recommendations for infrequently purchased products. Two different techniques are proposed, namely CFRRobin and CFAg Query. Instead of using the target user's query to search for products as normal search based systems do, the CFRRobin technique uses the products in which the target user's neighbours have shown interest as queries to retrieve relevant products, and then recommends to the target user a list of products by merging and ranking the returned products using the Round Robin method. The CFAg Query technique uses the products that the user's neighbours have shown interest in to derive an aggregated query, which is then used to retrieve products to recommend to the target user. Experiments conducted on a real e-commerce dataset show that both the proposed techniques CFRRobin and CFAg Query perform better than the standard Collaborative Filtering (CF) and the Basic Search (BS) approaches, which are widely applied by the current e-commerce applications. The CFRRobin and CFAg Query approaches also outperform the e- isting query expansion (QE) technique that was proposed for recommending infrequently purchased products.

Using incomplete online metric maps for topological exploration with the Gap Navigation Tree

This paper presents a general, global approach to the problem of robot exploration, utilizing a topological data structure to guide an underlying Simultaneous Localization and Mapping (SLAM) process. A Gap Navigation Tree (GNT) is used to motivate global target selection and occluded regions of the environment (called “gaps”) are tracked probabilistically. The process of map construction and the motion of the vehicle alters both the shape and location of these regions. The use of online mapping is shown to reduce the difficulties in implementing the GNT.
