An efficient and robust system for multi-person event detection in real world indoor surveillance scenes

Due to the popularity of security cameras in public places, it is of interest to design an intelligent system that can efficiently detect events automatically. This paper proposes a novel algorithm for multi-person event detection. To ensure greater than real-time performance, features are extracted directly from compressed MPEG video. A novel histogram-based feature descriptor that captures the angles between extracted particle trajectories is proposed, which allows us to capture motion patterns of multi-person events in the video. To alleviate the need for fine-grained annotation, we propose the use of Labelled Latent Dirichlet Allocation, a “weakly supervised” method that allows the use of coarse temporal annotations which are much simpler to obtain. This novel system is able to run at approximately ten times real-time, while preserving state-of-theart detection performance for multi-person events on a 100-hour real-world surveillance dataset (TRECVid SED).

Bribery and corruption in Australian local councils

This paper explores concerns about corruptio and bribery in Australian local government and provides guidance for policy-makers on how to control bribery and corruption. Lack of regulation is a major reason why local councils are not taking appropriate anti-corruption or bribery measures. The author urgers regulators to impose radical and mandatory requirements, especially reporting requirements, on local councils. Australia should also look to other countries for successful measures to curb bribery and corruption.

Public relations and engagement : theoretical imperatives of a multidimensional concept

Engagement has emerged as important concept in public relations, as stakeholders challenge the discourse of organizational primacy and organizations prioritize the need for authentic stakeholder involvement. As a multidimensional concept, engagement offers a foundation for building organizational relationships, and provides a means to facilitate community–organization interaction. This special issue on engagement and public relations presents a body of work that both explicates and expands the theoretical foundations of engagement, and contributes to scholarly understanding of its contexts, processes, and outcomes.

Discussions in Space

The Discussions in Space (DiS) offers an interactive, fast-paced social media channel for local governments, organisations or institutions to engage with local residents or visitors in public spaces, such as city squares, shopping malls, train or bus stations, museums. It facilitates a public discussion and opinion forum through the installation of a large public screen, which passers-by can directly interact with using their mobile phone’s SMS and/or Internet capabilities. The concise and fast-paced nature of the system is aimed to be particularly effective to engage with typically younger demographics, which may not provide their feedback through more traditional means.

The impact of socialisation on graduates’ public service motivation : a mixed method study

The need to attract and retain a high calibre cadre of public servants today has resulted in a renaissance of interest in public service motivation (PSM) within public management literature. This article outlines a study of PSM with graduate employees within an Australian public sector. The study extends our understanding of PSM by adopting a longitudinal, mixed method design, including surveys and individual interviews, to consider the effects of socialisation on levels of PSM. Results show an organisation's mission and values do not affect individual PSM while work type and communication style is vital and organisational socialisation can provide a negative influence.

Publishing the perished : the visibility of foreign death in Australian quality newspapers

The issue of media coverage of death has been under discussion by only a few scholars, and there have existed some disagreements as to just how present death is in public discourse in the Western world. This study adds to the literature on death by investigating the Australian media context. Specifically, it examines how journalists at two Australian quality newspapers, The Australian and the Sydney Morning Herald, cover death in their foreign news reporting. It finds that journalists express preferences for certain types of death, as well as for certain nationalities. Further, it sheds some light on just how visible death is in the news by arguing that, while present in the written word, the visual representation of death is still highly marginalised.

Unspeakably present: The (un)acknowledgment of diverse sexuality and gender human rights in Australian youth justice systems

A number of international human rights frameworks protect the rights of young people in contact with the criminal justice system in states parties, including Australia. These frameworks inform youth justice policy in Australia’s jurisdictions. While the frameworks protect young people’s right to non-discrimination on the grounds of ‘race’, religion and political opinion, the rights of young people to non-discrimination on the grounds of sexuality and gender diversity are not explicitly protected. This is problematic given that lesbian, gay, bisexual, trans, intersex and queer (LGBTIQ) young people appear over-represented in youth justice systems. This article argues that the exclusion of this group from human rights frameworks has an important flow-on effect: the marginalisation of the right of LGBTIQ young people to non-discrimination in policy and discourse that is informed by international human rights frameworks. After outlining the relevant frameworks, this article examines the evidence about LGBTIQ young people’s interactions with youth justice agencies, particularly police. The evidence indicates that the human rights of LGBTIQ young people are frequently breached in these interactions. We conclude by arguing that it is timely to consider how best to protect the human rights of LBGTIQ young people and keep their rights on the agenda.

A theoretical framework for reducing tendering costs in the procurement of infrastructure projects

Purpose of this paper One way in which the tendering process can be further improved is by reviewing and clarifying the high costs that participants face during the course of the tendering phase. The study aims to provide project teams working in construction tender preparation a clear picture of what to expect when tendering for infrastructure projects. Design/methodology/approach Firstly, a review of current literature on tendering in infrastructure projects is conducted to identify the associated costs affecting traditional and PPP procurements as well as the potential measures contributing to tendering cost-reduction. A theoretical framework and its corresponding research hypotheses, which are based on the literature reviewed, are then proposed. An industry-wide questionnaire survey is currently under design to solicit industry practitioners’ views on tendering costs and the associated tendering cost-reduction measures. The data collected in the survey will subject to statistical analysis to test the proposed research hypotheses, which will be reported in a forthcoming paper. Findings and value The direct and indirect costs in public-private procurement have been identified and have been categorised into internal and external costs arising from working on tender submissions. A theoretical framework, mainly composed of five mechanisms of cost reduction, has been proposed and will be tested in a forthcoming industry-wide questionnaire survey. Originality/value of paper The findings are expected to lead to a transparent tendering process in infrastructure procurement, in which there is increased engagement from the private sector as well as an increase in competitive tendering.

Enhanced student learning in accounting utilising web-based technology, peer-review feedback and reflective practices: A learning community approach to assessment

Higher education is becoming a major driver of economic competitiveness in an increasingly knowledge-driven global economy. Maintaining the competitive edge has seen an increase in public accountability of higher education institutions through the mechanism of ranking universities based on the quality of their teaching and learning outcomes. As a result, assessment processes are under scrutiny, creating tensions between standardisation and measurability and the development of creative and reflective learners. These tensions are further highlighted in the context of large undergraduate subjects, learner diversity and time-poor academics and students. Research suggests that high level and complex learning is best developed when assessment, combined with effective feedback practices, involves students as partners in these processes. This article reports on a four-phase, cross-institution and cross-discipline project designed to embed peer-review processes as part of the assessment in two large, undergraduate accounting classes. Using a social constructivist view of learning, which emphasises the role of both teacher and learner in the development of complex cognitive understandings, we undertook an iterative process of peer review. Successive phases built upon students’ feedback and achievements and input from language/learning and curriculum experts to improve the teaching and learning outcomes.

The nutritional profile of baby and toddler food products sold in Australian supermarkets

Background/Aims To examine the nutritional profile of baby and toddler foods sold in Australia. Methods Nutrient information for baby and toddler foods available at Australian supermarkets was collected between August and December 2013. Levels of declared energy, total fat, saturated fat, total sugar, sodium and estimated added sugar were examined, as well as the presence of additional micronutrients on the label. The Health Star Rating (HSR) system was used to determine nutritional quality. The range of products on offer was also examined by product type and by the age category for which the product was marketed. Results Of the 309 products included, 29 % were fortified. On a per 100 g basis, these 309 products provided a mean (±SD) of 476 ± 486 kJ, 1.6 ± 2.4 g total fat, 10.7 ± 12.2 g total sugar, 2.7 ± 7.4 g added sugar, and 33.5 ± 66.5 mg sodium. Fruit-based products or products with fruit listed as an ingredient (58 %) were the predominant product type. On the nutrition label, 42 % displayed at least one additional micronutrient while 37 % did not display saturated fat. The most common HSR was four stars (45 %) and 6? months was the most commonly identified targeted age group (36 %). Conclusions The majority of baby and toddler foods sold in Australian supermarkets are ready-made fruit-based products aimed at children under 12 months of age. Baby and toddler foods are overlooked in public policy discussions pertaining to population nutrient intake but their relatively high sugar content deriving from fruits requires close attention to ensure these foods do not replace other more nutrient dense foods, given children have an innate preference for sweet tastes.

Using political science to progress public health nutrition: a systematic review

Objective Poor dietary intake is the most important behavioural risk factor affecting health globally. Despite this, there has been little investment in public health nutrition policy actions. Policy process theories from the field of political science can aid understanding why policy decisions have occurred and identify how to influence ongoing or future initiatives. This review aims to examine public health nutrition policy literature and identify whether a policy process theory has been used to analyse the process. Design Electronic databases were searched systematically for studies examining policymaking in public health nutrition in high-income, democratic countries. Setting International, national, state and local government jurisdictions within high-income, democratic countries. Subjects Individuals and organisations involved in the nutrition policymaking process. Results Sixty-three studies met the eligibility criteria, most were conducted in the USA and a majority focused on obesity. The analysis demonstrates an accelerating trend in the number of nutrition policy papers published annually and an increase in the diversity of nutrition topics examined. The use of policy process theory was observed from 2003, however, it was utilised by only 14% of the reviewed papers. Conclusions There is limited research into the nutrition policy process in high-income countries. While there has been a small increase in the use of policy process theory from 2003, an opportunity to expand their use is evident. We suggest that nutrition policymaking would benefit from a pragmatic approach that ensures those trying to influence or understand the policymaking process are equipped with basic knowledge around these theories.

Creating change in government to address the social determinants of health: How can efforts be improved?

Background The evidence base for the impact of social determinants of health has been strengthened considerably in the last decade. Increasingly, the public health field is using this as a foundation for arguments and actions to change government policies. The Health in All Policies (HiAP) approach, alongside recommendations from the 2010 Marmot Review into health inequalities in the UK (which we refer to as the ‘Fairness Agenda’), go beyond advocating for the redesign of individual policies, to shaping the government structures and processes that facilitate the implementation of these policies. In doing so, public health is drawing on recent trends in public policy towards ‘joined up government’, where greater integration is sought between government departments, agencies and actors outside of government. Methods In this paper we provide a meta-synthesis of the empirical public policy research into joined up government, drawing out characteristics associated with successful joined up initiatives. We use this thematic synthesis as a basis for comparing and contrasting emerging public health interventions concerned with joined-up action across government. Results We find that HiAP and the Fairness Agenda exhibit some of the characteristics associated with successful joined up initiatives, however they also utilise ‘change instruments’ that have been found to be ineffective. Moreover, we find that – like many joined up initiatives – there is room for improvement in the alignment between the goals of the interventions and their design. Conclusion Drawing on public policy studies, we recommend a number of strategies to increase the efficacy of current interventions. More broadly, we argue that up-stream interventions need to be ‘fit-for-purpose’, and cannot be easily replicated from one context to the next.

Predictors of condom use behaviour among male street labourers in urban Vietnam using a modified Information-Motivation-Behavioral Skills (IMB) model

HIV risk in vulnerable groups such as itinerant male street labourers is often examined via a focus on individual determinants. This study provides a test of a modified Information-Motivation-Behavioral Skills (IMB) model to predict condom use behaviour among male street workers in urban Vietnam. In a cross-sectional survey using a social mapping technique, 450 male street labourers from 13 districts of Hanoi, Vietnam were recruited and interviewed. Collected data were first examined for completeness; structural equation modelling was then employed to test the model fit. Condoms were used inconsistently by many of these men, and usage varied in relation to a number of factors. A modified IMB model had a better fit than the original IMB model in predicting condom use behaviour. This modified model accounted for 49% of the variance, versus 10% by the original version. In the modified model, the influence of psychosocial factors was moderately high, whilst the influence of HIV prevention information, motivation and perceived behavioural skills was moderately low, explaining in part the limited level of condom use behaviour. This study provides insights into social factors that should be taken into account in public health planning to promote safer sexual behaviour among Asian male street labourers.

The functional liminality of the not-dead-yet students, or, how public schooling became compulsory: A glancing history

This paper redefines the focus for narrating histories of education in the USA through a ‘glancing history’. It highlights the important role played by ‘not-dead-yet students’ who occupied a liminal place on the scale of life in late nineteenth- and early twentieth-century. Traditional histories of education have been more singularly focused on the advent and dynamics of public schooling, ignoring the functionality of such child subjects to public schooling’s existence. This paper argues that public schools as historical objects cannot be understood outside of a broader trinary system of prior institutions that were established for ‘delinquent’ and ‘special’ children. These prior institutions facilitated the formation of ‘the public’ in public schooling less in opposition to ‘the private’ and more in consonance with ‘the human’. The existence of prior institutions enabled the enforcement of compulsory attendance legislation. Compulsory attendance legislation, in place across all existing states by 1918, was concerned more with the conditions for exclusion and exemption than with compelling attendance. Thus, at the most immediate level, this paper historicizes some of the discursive and hence institutional events that linked an array of tutelary complexes by the early 1900s, and which enabled such legislation. This part of the argument extends the notion of institution to consider broader places of confinement and systematicity. It examines the prior practice of reservation and slavery systems, and the efficacy they lent to further institutionalized segregation in the USA. At a second level, the narrative reflects on how such a narration has become possible. It considers how histories of education can currently be rethought and rewritten around the notion of dis/ability, historicizing the formation of dis/ability as identity categories made noticeable in part (and circularly) through the crystallization of a segregated but linked common schooling system. The paper thus provides a counter-memory against dominant economic foundationalist and psychomedical accounts of schooling’s past. It documents both ‘external’ conditions of possibility for public schooling’s emergence and ‘internal’ effects that emerged through the experiences of confinement

Travel behaviours of immigrants in Queensland, Australia

The aim of this research is to determine if there is a significant difference in public transport usage between Australian-born and overseas-born travellers in South East Queensland and identify if further investigation into this demographic factor is necessary. Using the household travel survey data of Southeast Queensland, Australia, this paper analyses the travel behaviours of immigrants and non-immigrants in the region. The immigrant population is divided into six sub-groups based on their continent of origin. The analysis results suggest that immigrants are more likely to use public transit in Brisbane over other regions in the study. Overall, this research strongly suggests that in Australia, a higher proportion of the immigrant population is more likely to use public transit compared to the proportion of the local population.
