A Tobit model for analyzing speed limit compliance in work zones

Poor compliance with speed limits is a serious safety concern in work zones. Most studies of work zone speeds have focused on descriptive analyses and statistical testing without systematically capturing the effects of vehicle and traffic characteristics. Consequently, little is known about how the characteristics of surrounding traffic and platoons influence speeds. This paper develops a Tobit regression technique for innovatively modeling the probability and the magnitude of non-compliance with speed limits at various locations in work zones. Speed data is transformed into two groups���continuous for non-compliant and left-censored for compliant drivers���to model in a Tobit model framework. The modeling technique is illustrated using speed data from three long-term highway work zones in Queensland, Australia. Consistent and plausible model estimates across the three work zones support the appropriateness and validity of the technique. The results show that the probability and magnitude of speeding was higher for leaders of platoons with larger front gaps, during late afternoon and early morning, when traffic volumes were higher, and when higher proportions of surrounding vehicles were non-compliant. Light vehicles and their followers were also more likely to speed than others. Speeding was more common and greater in magnitude upstream than in the activity area, with higher compliance rates close to the end of the activity area and close to stop/slow traffic controllers. The modeling technique and results have great potential to assist in deployment of appropriate countermeasures by better identifying the traffic characteristics associated with speeding and the locations of lower compliance.

Who are Australia���s information educators?

In recent years there has been considerable discussion afforded to the challenges facing the future of information education in Australia. This paper reports a study that explored the characteristics and experiences of Australia���s information educators. The study was undertaken as part of a larger project, which was designed to establish a consolidated and holistic picture of the Australian information profession, and identify how its future education could be mediated in a cohesive and sustainable manner. Sixty-nine of Australia���s information educators completed an online questionnaire that gathered data on aspects such as age, gender, rank, qualifications, work activities, and job satisfaction. The key findings from this study confirm that a number of pressing issues are confronting information educators in Australia. For example, Australia���s information educators are considerably older than that the total Australian academic workforce; over half the information educators who participated in the study are looking to retire in the next ten years; and, Australia���s information educators spend more time on service activities then other disciplines within Australia���s education system and are place a stronger importance on teaching over research. Left unaddressed these issues will have significant implications for the future of information education as well as the broader information profession. Many of the key observations drawn from this study may also have relevance to other disciplines in the Australian educational context.

Life story work and social work practice : a case study with ex-prisoners labelled as having an intellectual disability

In common with other professions social workers have the power to articulate certain ������truths������ about the people who use their services (Hare Mustin, 1994). These knowledge statements about people, often situated in case files may become the only background information of the lived experience for people with disability (Gillman, Swain, & Heyman, 1997). Social workers need to develop interviewing, assessment and recording practices that give precedent to the worldview of service users, if they are to truly understand and respond effectively to people's lives (Bigby, 2007). One such way of doing this is by adopting a life story approach to working with vulnerable people, which can provide a holistic stance to a person's social reality (Ortiz, 1985). This article outlines the use of this approach in research with Queensland ex-prisoners who were labelled as having an intellectual disability. By explaining the process used by the first author (hereafter known as the researcher), the methodological findings of this study illustrate how life story work can contribute to social work practice.

The impact of employment-level characteristics on work-life interference in school aged children

Work���life interference is important for school-aged workers because it influences their educational outcomes/career aspirations. Although research highlights the role of work hours in determining work���life interference for these workers, work/job-level characteristics have received limited attention. Using survey data from Queensland school students who work part-time, we assess the influence of a range of employment-level variables on work���life interference. The results of multiple regression analysis indicate work���life interference is exacerbated by having low trust in managers and limited scope to refuse work hours and stability in work hours, emphasising the importance of organisational variables in integrating work and non-work spheres for school-aged workers.

Social work with marginalised people who have a mild or borderline intellectual disability : practicing gentleness and encouraging hope

People with mild or borderline intellectual disabilities are a group of people who usually do not meet the eligibility criteria for specialist disability services, yet are high users of many generalist services, such as mental health, child protection, and criminal justice systems. They may traverse many services, often entering, exiting, and returning to the same service providers with few positive results. This article explores the practice approach of the Meryton Association, a medium-sized nongovernment agency located in Brisbane, Australia. The Meryton Association provides social work support to people with mild to borderline intellectual disabilities, actively assisting this group to build relationships, resources, knowledge, and autonomy in their everyday lives. Using qualitative in-depth interviews with Meryton Association staff and secondary analysis of Meryton Association policy and practice documents, the challenges and opportunities of using this practice approach have been documented. The article proposes that specialist services are needed that use a developmental approach, stress the importance of relationship, and the need to practice gentleness and hope in social worker-client interaction.

The work of Media Arts in the age of digital production

This chapter uses as a beginning point Walter Benjamin���s famous essay ���The work of art in the age of technological reproducibility���(1935/2008) to discuss Media Arts education. It locates ���Media Arts��� at the intersection of three key ideas: 1) media arts products as objects for popular and everyday consumption and intervention by individuals and broader audiences; 2) materiality and how individuals use their bodies and technologies to produce, combine and share digital materials and; 3) the construction of aesthetic knowledge and how this relates to critical and conceptual thinking. These ideas are discussed in the context of the development of curriculum for students at all ages of schooling, with specific attention given to the knowledge and skills students might develop within Media Arts education in primary schools. Examples from a Media Arts project in a primary school in Australia ��� where a new Media Arts national curriculum has been developed ���are provided to illustrate the key ideas discussed in the chapter.

Child observation as teachers' work in contemporary Australian early childhood programs

This article reports data from a study of how teachers use child observations in one State in Australia. It argues that the current economic and political climate has meant changes for most early childhood settings catering for children prior to school entry. How teachers in these various settings deal with changes in relation to child observation depends on the contexts in which they work. The paper suggests that the purpose of observing children is changing and that traditionally accepted ways of writing child observations may be under threat.

Building the science and innovation base: work, skills and employment issues

This Special Issue of New Technology, Work and Employment has been prompted by the increasing awareness in many countries of the need to maintain and grow their science and innovation base. The development of science, engineering, technology and mathematics (STEM) skills and capacity is seen as vital for economic development and prosperity through its impact on national and regional research and development (R&D), technological advancement, and innovation potential.

Women IN Sport or Women OR Sport - The search for work/sport/life balance.

The current ���holy grail��� for our health and well-being centres around the search for, and establishment of, a work/life balance. For many individuals, this appears to be an ever-elusive goal ��� forever slipping from our grasp as we juggle the day-to-day battle for our attention and time from an array of sources. When we add the word ���Women��� to this mix, often the number of sources related to these demands multiplies in alignment with the number of roles we fill. To take this to even another level, consider the addition of the words ���Sport��� or ���Elite Athlete��� to ���Women��� and ���Work/Life Balance���, and the search for the ���holy grail��� becomes more literal! Many sportswomen at the elite level face significant challenges in balancing working to support themselves and/or their families, studying to lay the foundations of a post-sport career, (often) spending the equivalent of full-time hours training towards their sporting goals, and additionally investing in the things that are important for them outside of these two areas ��� the ���Life��� component. Getting the work/life balance ���balanced��� has been suggested to be a key component of investing in our health and well-being. The same is applicable to sportswomen, with the added suggestion that if the balance between work/sport/life is achieved, this can positively impact upon sporting performance itself. These ideas and observations will be explored via experience within the Australian elite sporting environment from a psychologist���s perspective, with questions and invitations for further discussion.

User-led innovation in call center knowledge work

So called ���knowledge work��� is seen as integral to post-industrial society and, for some, information and communications technologies (ICTs) are critical enablers of the associated practices. Many still propose the technologically deterministic route of rolling out ICTs and expecting that users will, and indeed can, ���download��� what they know into a system that can then be used in a number of ways. This approach is usually underpinned by the predominant assumption that the system will be developed by one group (developers) and used by another group (users). In this paper, we report on an exploratory case study of the enactment of ICT supported knowledge work in a human resources contact center which illustrates the negotiable boundary between the developer and user in local level innovation processes. Drawing upon ideas from the social shaping of technology, we examine how discussions regarding producer-user relations in innovation processes require a degree of greater sophistication as we show how users often develop (or produce) technologies and work practices in situ���in this case, to enable knowledge work practices and contribute to the project of constructing the knowledge component of professional identity. Much has been made of contextualizing the user; further work is required to contextualize the developer as a user and understand the social actors in ICT innovation environments who straddle both domains

Breathe easier online : evaluation of a randomized controlled pilot trial of an internet-based intervention to improve well-being in children and adolescents with a chronic respiratory condition

Background Chronic respiratory illnesses are the most common group of childhood chronic health conditions and are overrepresented in socially isolated groups. Objective To conduct a randomized controlled pilot trial to evaluate the efficacy of Breathe Easier Online (BEO), an Internet-based problem-solving program with minimal facilitator involvement to improve psychosocial well-being in children and adolescents with a chronic respiratory condition. Methods We randomly assigned 42 socially isolated children and adolescents (18 males), aged between 10 and 17 years to either a BEO (final n = 19) or a wait-list control (final n = 20) condition. In total, 3 participants (2 from BEO and 1 from control) did not complete the intervention. Psychosocial well-being was operationalized through self-reported scores on depression symptoms and social problem solving. Secondary outcome measures included self-reported attitudes toward their illness and spirometry results. Paper-and-pencil questionnaires were completed at the hospital when participants attended a briefing session at baseline (time 1) and in their homes after the intervention for the BEO group or a matched 9-week time period for the wait-list group (time 2). Results The two groups were comparable at baseline across all demographic measures (all F < 1). For the primary outcome measures, there were no significant group differences on depression (P = .17) or social problem solving (P = .61). However, following the online intervention, those in the BEO group reported significantly lower depression (P = .04), less impulsive/careless problem solving (P = .01), and an improvement in positive attitude toward their illness (P = .04) compared with baseline. The wait-list group did not show these differences. Children in the BEO group and their parents rated the online modules very favorably. Conclusions Although there were no significant group differences on primary outcome measures, our pilot data provide tentative support for the feasibility (acceptability and user satisfaction) and initial efficacy of an Internet-based intervention for improving well-being in children and adolescents with a chronic respiratory condition.

Integrated chronic disease management in primary-secondary care : a systematic literature review of the evidence

Introduction: Diabetes has traditionally been managed as a single chronic disease state, but it exists with co-morbidities such as depression and metabolic syndrome. Treatment is multifaceted, requiring both primary and secondary care, however, the delivery of diabetes care is often fragmented. Integrated chronic disease management is a growing model of interest, and is underpinned by the chronic care model (CCM), devised as a guide for primary care management of patients with chronic conditions. The model identifies six key elements for effective care, and has shown promise in improving the management of diabetes. Aim: To find empirical evidence of integrated care interventions targeted at co-morbidities including diabetes, across primary/secondary care. Method: A systematic review of peer reviewed literature from PubMed, CINAHL, Embase, Cochrane Library and Joanna Briggs was performed. Studies were reviewed according to inclusion criteria- studies published in English, between 2004-2014, empirical studies, studies with evidence of primary/secondary implementation, and those dealing with chronic co-morbid disease states. Results: 51 studies met the inclusion criteria. Included studies were mostly from the US (38), with five from Australia, UK (2), Canada (2), Netherlands (1), Norway (1), Ireland (1), and one multi-country study. It was found that all interventions adopted at least one (average 3-4) of the chronic care model, with the majority implementing delivery system redesign activities within the primary care practice/s. We found evidence of interventions which significantly reduced emergency department and hospital admissions, improved processes of care, patient health outcomes such as HbA1c, improved patient satisfaction, and reduced costs. Conclusion/Implications for practice: Diabetes exists as a co-morbid disease, requiring both primary and secondary care. We found that integrated care interventions adopting elements of the chronic care model positively impacted on patient outcomes, service utilisation, as well as costs. This review has highlighted that it may not be necessary to adopt all CCM elements to improve clinical outcomes, patient satisfaction and costs.

Blended delivery and online assessment : scaffolding student reflections in work-integrated learning

This paper documents a teaching innovation addressing the challenges of embedding and assessing reflective practice in work-integrated learning, specifically marketing internships. We identify four issues relating to this problem: lack of knowledge or skill for reflection, limitations of physical journals, facilitation of different forms of reflection, and suitable models for teaching and assessing reflection. The paper outlines a blended approach combining face-to-face workshops and online resources, and using online reflective journals and digital stories as assessment. The approach and assessment tasks can be implemented in a variety of marketing and business units.

Young people, citizenship and public space : a work in progress on issues and consequences

Tensions frequently occur when children and young people seek to make use of a multitude of public spaces (Loader 1996; White 1999).In Australia over a number of years, various strategies have been adopted by local councils, police and other stakeholders such as business groups, to respond to such tensions and disputes. However, rarely are children and young people involved in meaningful ways in the design and control of public space that reflects their needs and aspirations (White 1999; Freeman and Riordan 2002). This paper argues for a broader conceptualisation of the rights of citizenhip to include rights to use public space by children and young people.

Enhancing social work interprofessional learning through across university and industry collaboration : early steps in the Advanced Health Directives Project

There is ongoing interest in strategies for enhancing the reciprocal benefit derived from social work placements by students, host agencies, and universities. There is also recognition that interprofessional learning is an important aspect of social work education,and that field education placements have a role to play in this learning. This article reports on an innovation in community-engaged learning undertaken between a major public hospital and a university, where a team of social work and law students contributed to a focused inquiry into a socio-legal practice challenge faced by the hospital, namely the use of Advanced Health Directives (AHDs).Various collaborative processes involved in the early phase of the AHD project are reflected on by participants.A preliminary evaluation supports the value of taking a systematic approach to university���industry engagement where interprofessional collaboration occurs vertically and horizontally within and across university and placement hosting agencies.
