Adolescence and emerging adulthood are key developmental stages with high risk for trauma exposure and the development of mental and substance-use disorders (SUDs). This study aims to compare the clinical profiles of adolescents (aged 12–17 years) and emerging adults (aged 18–25 years) presenting for treatment of posttraumatic stress disorder (PTSD) and SUD.

Data was collected from the baseline assessment of individuals (n = 55) taking part in a randomized controlled trial examining the efficacy of an integrated psychological therapy for co-occurring PTSD and SUDs (PTSD+SUD) in young people.

Both age groups demonstrated complex and severe clinical profiles, including high-frequency trauma exposure, and very poor mental health reflected on measures of PTSD, SUD, suicidality and domains of social, emotional, behavioral and family functioning. There were few differences in clinical characteristics between the two groups.

Similarity between the two groups suggests that the complex problems seen in emerging adults with PTSD + SUD are likely to have had their onset in adolescence or earlier and to have been present for several years by the time individuals present for treatment.

To the best of the authors’ knowledge, this is the first study to compare the demographic and clinical profiles of adolescents and emerging adults with PTSD + SUD. These findings yield important implications for practice and policy for this vulnerable group. Evidence-based prevention and early intervention approaches and access to care are critical. Alongside trauma-focused treatment, there is a critical need for integrated, trauma-informed approaches specifically tailored to young people with PTSD + SUD.

Education tends to colonize. Established authorities (teachers, curricula, and examinations) instruct newcomers, extending conditional membership. This presents a dilemma for teachers seeking to instill in their students habits of critical, creative, and lateral thinking. In Australia as elsewhere, blueprint educational documents embody lofty aspirational statements of inclusion and investment in people and their potential. Yoked to this is a regime routinely imposing high-stakes basic-skills testing on school students, with increasingly constrictive ways of doing, while privileging competition over collaboration. This chapter explores more informal, organic learning. This self-study narrative inquiry explores my career in terms of a struggle to be my most evolved, enlightened self, as opposed to a small-minded, small-hearted mini-me. To balance this, I examine responsible autonomy (including my own), rather than freedom. This chapter also explores investment in humans, with the reasonable expectation of a return on that investment. It draws and reflects upon events in or impacting my hometown, Sydney, Australia, focusing largely on WorldPride, the Women's World Cup, and a referendum on an Indigenous voice to parliament, all of which took place as I compiled this chapter. Accordingly, the narrative focuses primarily on sexuality, gender, and race. I explore the capacity of my surroundings to teach me and my capacity to learn from my surroundings. The findings and discussion comprise diary-type entries of significant events and their implications for (my) excessive entitlement. The final section of this chapter reviews what and how I have learned.

House price fluctuations send vital signals to many parts of the economy, and long-term predictions of house prices are of great interest to governments and property developers. Although predictive models based on economic fundamentals are widely used, the common requirement for such studies is that underlying data are stationary. This paper aims to demonstrate the usefulness of alternative filtering methods for forecasting house prices.

We specifically focus on exponential smoothing with trend adjustment and multiplicative decomposition using median house prices for Sydney from Q3 1994 to Q1 2017. The model performance is evaluated using out-of-sample forecasting techniques and a robustness check against secondary data sources.

Multiplicative decomposition outperforms exponential smoothing at forecasting accuracy. The superior decomposition model suggests that seasonal and cyclical components provide important additional information for predicting house prices. The forecasts for 2017–2028 suggest that prices will slowly increase, going past 2016 levels by 2020 in the apartment market and by 2022/2023 in the detached housing market.

We demonstrate that filtering models are simple (univariate models that only require historical house prices), easy to implement (with no condition of stationarity) and widely used in financial trading, sports betting and other fields where producing accurate forecasts is more important than explaining the drivers of change. The paper puts forward a case for the inclusion of filtering models within the forecasting toolkit as a useful reference point for comparing forecasts from alternative models.

To the best of the authors’ knowledge, this paper undertakes the first systematic comparison of two filtering models for the Sydney housing market.

High-density development requires large land parcels, but fragmented land ownership can impede redevelopment. While earlier compact city development in Sydney occurred on large-scale brownfield sites, redeveloping and re-amalgamating older strata-titled properties is now integral to further densification. The purpose of this study is to examine collective sales activity in one Sydney suburb where multiple strata-titled redevelopments and re-amalgamations have been attempted. The authors explore how owners navigate the process of selling collectively, focusing on their experience of legislation introduced to facilitate this process, the Strata Schemes Development Act 2015 [New South Wales (NSW)].

By reviewing sales listings, development applications and media coverage, and interviewing owners, lawyers and estate agents, the authors map out collective sale activity in a case study area in Sydney’s northwest.

Strata collective sales are slow and difficult to complete, even when planning and market drivers align. Owners find the Strata Scheme Development Act 2015 (NSW) difficult to navigate and it has not prevented strategic blocking attempts by competing developers. The long timelines required to organise collective sales can result in failure if the market shifts in the interim. Nonetheless, owners remain interested in selling collectively.

This case study is important for understanding the barriers to redevelopment to achieve a more compact city. It highlights lessons for other jurisdictions considering similar legislative changes. It also suggests that legislative change alone is insufficient to resolve the planning challenges created by hyper-fragmentation of land through strata-title development.

Informational conflict and uncertainty are common features across a range of sources, topics and tasks. Search engines and their presentation of results via search engine results pages (SERPs) often underpinned by knowledge graphs (KGs) are commonly used across tasks. Yet, it is not clear how search does, or could, represent the informational conflict that exists across and within returned results. The purpose of this paper is to review KG and SERP designs for representation of uncertainty or disagreement.

The authors address the aim through a systematic analysis of material regarding uncertainty and disagreement in KG and SERP contexts. Specifically, the authors focus on the material representation – user interface design features – that have been developed in the context of uncertainty and disagreement representation for KGs and SERPs.

Searches identified n = 136 items as relevant, with n = 4 sets of visual materials identified from these for analysis of their design features. Design elements were extracted against sets of design principles, highlighting tensions in the design of such features.

The authors conclude by highlighting two key challenges for interface design and recommending six design principles in representing uncertainty and conflict in SERPs. Given the important role technologies play in mediating information access and learning, addressing the representation of uncertainty and disagreement in the representation of information is crucial.

This paper aims to describe the design and evaluation of a pilot leadership development programme for infection prevention and control (IPAC) professionals during the COVID-19 pandemic. The programme’s aim was to improve IPAC knowledge and capacity in the health-care system by developing the leadership skills and capacities of novice and advanced Infection Control Professionals (ICPs), to respond flexibly, and competently, in their expanding and ever-changing roles.

The leadership programme was piloted with seven nurses, who were part of a clinical nursing team in New South Wales, Australia, over a 12-month period between 2021 and 2022. The programme was designed using a leadership development framework underpinned by transformational leadership theory, practice development approaches and collaborative and experiential learning. These principles were applied during programme design, with components adapted to learners’ interests and regular opportunities provided for collaboration in active learning and critical reflection on workplace experiences.

The authors’ evaluation suggests that the programme was feasible, acceptable and considered to be effective by this cohort. Moreover, participants valued the opportunities to engage in active and experience-based learning with peers, and with the support of senior and experienced ICPs. The action learning sets were well-received and allowed participants to critically reflect on and learn from one another’s experiences. The mentoring programme allowed them to apply their developing leadership skills to real workplace challenges that they face.

Despite a small sample size, the authors’ results provide empirical evidence about the effectiveness of using a practice development approach for strengthening ICP leadership capacity. The success of this pilot study has paved the way for a bigger second cohort of participants in the programme, for which further evaluation will be conducted.

The success of this leadership programme reflects both the need for leadership development in the IPAC professions and the applicability of this approach, with appropriate facilitation, for other professions and organizations.

ICP leadership programmes have not been previously reported in the literature. This pilot study builds on the growing interest in IPAC leadership to foster health system responsiveness and change.

The purpose of this paper is to present the results of a scoping review on the implementation of Article12 in health care. The scoping review will provide a summary and overview of the key concepts and published literature on this topic internationally. Article 12 of the United Nations Convention on the Rights of the Child (1989) states that children have a right to express their views, to have them heard and for their views to be given due weight in all matters that affect them. Despite increased calls for Article 12 to be given attention in health care, there is little evidence to suggest this has been well implemented and embedded in Australian health-care delivery. The scoping review was undertaken to provide a summary and overview of the key concepts and published literature on this topic internationally.

A five-step methodological framework described by Arksey and O’Malley (2005) was used to undertake the scoping review. Preferred Reporting Items for Systematic Reviews and Meta-Analysis was used as a guideline for undertaking the study selection.

Children are still not routinely involved in health-care decision-making, are frequently left out of service planning and evaluation and the perception that they lack the capability to make rational decisions persists.

While there has been a focus on research that investigates children’s participation in health-care decision-making in recent years, there is little that directs attention specifically to the implementation of Article 12, particularly in Australian health care. Recommendations are made for further research in these areas.

The purpose of this study is to investigate the influence of design for lean six sigma (DFLSS) on operational functions of the innovation management model by appraising an innovation management assessment framework.

An empirical approach for evaluating causal relationships among various constructs in the model phases that identify optimum pathways in achieving commercial success was adopted. A quantitative analysis of survey data were collected from large, medium and small organiations, including incubators in ANZ (Australia, New Zealand) and TMSV (Thailand, Malaysia, Sri Lanka and Vietnam).

The structural equation modelling recursive path analysis results of the model provide empirical evidence and pathways through the various constructs considered in the model. All these pathways lead to delivering optimum commercialization success (CS). Furthermore, DFLSS is confirmed as an enabler and has direct one-to-one and indirect influence on all the operational function constructs of the model including commercial success.

This study had a relatively small sample size of completed responses obtained from the population and a constrained ability to compare commercialization success (CS) between the two regions in the dataset. Future studies could be conducted on a global scale to increase responses.

The research findings enabled the development of important and practical guidelines for managers and innovation practitioners engaged in planning and management of innovation.

This research offers a holistic approach for integrating DFLSS with stage gate phases of innovation management assessment framework, supported by empirical evidence, to aid organizations in effectively managing the innovation process and achieving greater success in commercialization.

This paper aims to investigate the factors that influence millennial purchase behaviour, brand choice and distribution channel selection in an evolving technology-driven environment.

The study was exploratory, using qualitative methods of personal interviews and some ethnographic observations to collect data from 585 millennials from ten cities in nine African countries.

Findings from the study confirm and support the critical role of e-commerce in facilitating millennials engagement with brands, highlighting how brand purchases are integral to their lifestyle choices. There is an overwhelming confirmation of the importance of influencer marketing and social media in shaping purchase decisions, with new insights into the role of local micro-influencers and social networks. The findings from the study highlight the pivotal role of a brand’s country of origin in influencing millennials’ brand preferences. The study supports and advances insights into the importance of online shopping and diverse factors influencing millennials’ selection of distribution channels.

There is an opportunity to leverage the growing mobile telephone penetration and social media usage to develop innovative integrated marketing communications strategies. There are opportunities for co-creating marketing communication campaigns with millennials in different settings. These are outlined in the practical implications section.

The paper is based on original empirical data collected from ten countries and explores the behaviour of a growing but under-researched segment of millennials in Africa.

Avoided emissions refer to greenhouse gas emission reductions that are a result of using a product or are emission removals due to a decision or an action. Although there is no uniform standard for calculating avoided emissions, market actors have started referring to avoided emissions as “Scope 4” emissions. By default, making a claim about Scope 4 emissions gives an appearance that this Scope of emissions is a natural extension of the existing and accepted Scope-based emissions accounting framework. The purpose of this study is to explore the implications of this assumed legitimacy.

Via a desktop review and interviews, we analyse extant Scope 4 company reporting, associated accounting methodologies and the practical implications of Scope 4 claims.

Upon examination of Scope 4 emissions and their relationship with Scopes 1, 2 and 3 emissions, we highlight a dynamic and interdependent relationship between quantification, commensuration and standardization in emissions accounting. We find that extant Scope 4 assessments do not fit the established framework for Scope-based emissions accounting. In line with literature on the territorializing nature of accounting, we call for caution about Scope 4 claims that are a distraction from the critical work of reducing absolute emissions.

We examine the implications of assumed alignment and borrowed legitimacy of Scope 4 with Scope-based accounting because Scope 4 is not an actual Scope, but a claim to a Scope. This is as an act of accounting territorialization.
