In light of concerning evidence that many young people with mental disorders are not receiving appropriate mental health intervention, school-based mental health screening has been advocated as one way to improve identification of at-risk youth. Despite having much promise, universal screening in schools remains a relatively uncommon practice internationally. Various barriers that deter school psychologists and counsellors from screening have been identified, including lack of resourcing to implement screening, lack of knowledge about the mechanics of how to carry out a screening program, and concern about how to manage the anticipated increased workload generated by following up identified students. In this practice-based paper we discuss a four-stage process that guides school psychologists and counsellors in the establishment of a school-based screening program, with specific reference to overcoming perceived barriers.

There is growing evidence of an escalation of depression in young people. In light of this, schools are increasingly being confronted with the challenge of how to best manage students with depressive disorders. Such management includes consideration of the academic, behavioural, social and emotional implications of the disorder. This article provides school practitioners and management with a review of what constitutes ‘best practice’ in school management of students with depressive disorders. It adopts the mental health intervention framework of the Institute of Medicine, considering how school-based intervention occurs across the four domains of mental health promotion, prevention, case identification and treatment, as well as maintenance of students with or at-risk of depression. It provides a checklist for practitioners at each stage of the Institute of Medicine intervention spectrum. Moreover, it takes the view that best practice in psychology is always evidence-based practice, although discerning a clear path through the available research is not always obvious.

The ‘16Up’ study conducted at the QIMR Berghofer Medical Research Institute from January 2014 to December 2018 aimed to examine the physical and mental health of young Australian twins aged 16−18 years (N = 876; 371 twin pairs and 18 triplet sets). Measurements included online questionnaires covering physical and mental health as well as information and communication technology (ICT) use, actigraphy, sleep diaries and hair samples to determine cortisol concentrations. Study participants generally rated themselves as being in good physical (79%) and mental (73%) health and reported lower rates of psychological distress and exposure to alcohol, tobacco products or other substances than previously reported for this age group in the Australian population. Daily or near-daily online activity was almost universal among study participants, with no differences noted between males and females in terms of frequency or duration of internet access. Patterns of ICT use in this sample indicated that the respondents were more likely to use online information sources for researching physical health issues than for mental health or substance use issues, and that they generally reported partial levels of satisfaction with the mental health information they found online. This suggests that internet-based mental health resources can be readily accessed by adolescent Australians, and their computer literacy augurs well for future access to online health resources. In combination with other data collected as part of the ongoing Brisbane Longitudinal Twin Study, the 16Up project provides a valuable resource for the longitudinal investigation of genetic and environmental contributions to phenotypic variation in a variety of human traits.

Based on archival material and interviews, the paper argues that the autonomy of Hong Kong's institutions of higher education has varied since 1911, with the colonial state initially exercising tight control and relaxing it especially as the transfer of sovereignty over Hong Kong approached. China has sought to reassert control especially since 2014 in what continues to be contested space.

Jeankempite, Ca5(AsO4)2(AsO3OH)2(H2O)7, is a new mineral species (IMA2018-090) discovered amongst coatings of arsenate minerals on oxidised copper arsenides from the Mohawk No. 2 mine, Mohawk, Keweenaw County, Michigan, USA. The new mineral occurs as lamellar bundles of colourless to white plates up to 1 mm wide and is visually indistinguishable from guérinite, with which it forms intergrowths. Jeankempite is transparent to translucent with a waxy lustre and white streak, is non-fluorescent under longwave and shortwave ultraviolet illumination, has a Mohs hardness of ~1.5 and brittle tenacity with uneven fracture. Crystals are flattened on {01$\bar{1}$} and exhibit perfect cleavage on {01$\bar{1}$}. Optically, jeankempite is biaxial (+), α = 1.601(2), β = 1.607(2), γ = 1.619(2) (white light); 2Vmeas. = 72(2)° and 2Vcalc. = 71.0°. The empirical formula is (Ca4.97Na0.013Mg0.017)(As3.99S0.01)4O23H16, based on 23 O and 16 H atoms per formula unit. Thermogravimetric analysis indicates that jeankempite undergoes four weight losses totalling 16.82%, close to the expected loss of 16.30%, corresponding to eight H2O. Jeankempite is triclinic, P$\bar{1}$, a = 6.710(6), b = 14.901(14), c = 15.940(15) Å, α = 73.583(12)°, β = 81.984(12)°, γ = 82.754(12)°, V = 1507(2) Å3 and Z = 3. The final structure was refined to R1 = 0.0591 for 2781 reflections with Iobs > 3σI. The crystal structure of jeankempite is built from a network of edge- and vertex-sharing CaO6, CaO7 and AsO4 polyhedra, and we hypothesise that the new mineral has formed due to a topotactic reaction brought on by dehydration of preexisting guérinite.

This article reports on an evaluation of the Keeping Children Safe parent education programme run in Central West New South Wales. The programme, conducted since 2004, and continuing today, primarily targets parents of children at risk and other vulnerable and disadvantaged families. The evaluation covers a 13-year period, from the first group held in May 2004 to February 2017. From the beginning, the authors strategically endeavoured to recruit and retain parents from the target group. Findings from the literature indicate that this group is difficult to engage and retain in parent education groups. Parents targeted for the groups in this study were generally not receiving parent education elsewhere. Using mixed methods, the facilitators have continuously evaluated the programme in terms of attendance rates, process and impact. The results of these evaluations show successful recruitment and retention of participants from the target group over the 13 years of the evaluation reporting period and indicate that the programme’s immediate impact on participants has been favourable. The findings complement other programme evaluations focusing on recruitment and retention to programmes in the child protection context and on hard-to-reach clients. The authors also argue the importance of education for parents about child abuse and neglect.

In this note we consider parabolic subroot systems of a complex simple Lie Algebra. We describe root theoretic data of the subroot systems in terms of that of the root system and we give a selection of applications of our results to the study of generalized flag manifolds.

Attendance at overnight school camp is an integral component of the Australian educational landscape. However, some students are reluctant to attend camp, while others refuse to attend at all. School psychologists play an important part in supporting these students and their families, and teachers. While much is published about general school refusal, there is surprisingly little attention given to the specific management of school camp refusal and reluctance. This article summarises the contribution of the related theoretical areas of childhood anxiety, school refusal, and homesickness. It then outlines, through a case study example, a management approach for school psychologists, from presentation of the problem to assessment, through to informed intervention, including a suite of strategies to support the student, parents and teachers, who have duty of care during camps.

The problem of active feedback control of fluid flows falls into a class of problems in the area of distributed parameter control. Distributed parameter systems are typically defined by partial differential equations that model the time and spatial evolution of the process. We consider the problem of locating sensors for effective feedback control of a fluid flow problem described by the Navier–Stokes equations. In this setting, the state of the system is the velocity field $\boldsymbol{v}(t,x)$, and hence all feedback laws are a function of this velocity field or, in most practical settings, a function of sensor outputs. In many designs, the feedback control law can be represented as a linear function of the state defined by an integral operator with a kernel function called the functional gain. In this paper we show that these functional gains can be used to determine effective sensor placement in complex flow control applications. The approach is to choose measurements of the state that would provide good quadrature points for the integral operator. We provide a computational validation of this approach by controlling the vortex shedding in a two-dimensional cylinder flow using a pair of fluid actuators on the cylinder surface. This model is linearized about the mean flow and a feedback control is designed by pole placement. Distributed parameter control theory yields the existence and form of the functional gains which are used to locate sensors. In particular, we use the location of the supports of the functional gains to determine two sets of four sensor locations in the wake. One of these measurement sets coincides with large magnitudes of the gain and the other set coincides with small magnitudes. Numerical experiments with a reduced-order model confirm superior performance of the closed-loop (CL) system using the former sensor set. We also show that choosing sensor locations associated with small magnitudes of the functional gains actually destabilizes the CL system.

In the United States alone, ∼14,000 children are hospitalised annually with acute heart failure. The science and art of caring for these patients continues to evolve. The International Pediatric Heart Failure Summit of Johns Hopkins All Children’s Heart Institute was held on February 4 and 5, 2015. The 2015 International Pediatric Heart Failure Summit of Johns Hopkins All Children’s Heart Institute was funded through the Andrews/Daicoff Cardiovascular Program Endowment, a philanthropic collaboration between All Children’s Hospital and the Morsani College of Medicine at the University of South Florida (USF). Sponsored by All Children’s Hospital Andrews/Daicoff Cardiovascular Program, the International Pediatric Heart Failure Summit assembled leaders in clinical and scientific disciplines related to paediatric heart failure and created a multi-disciplinary “think-tank”. The purpose of this manuscript is to summarise the lessons from the 2015 International Pediatric Heart Failure Summit of Johns Hopkins All Children’s Heart Institute, to describe the “state of the art” of the treatment of paediatric cardiac failure, and to discuss future directions for research in the domain of paediatric cardiac failure.

Scholarly work in the 1990s indicated that the values of civil servants in late colonial Hong Kong were evolving from those of classical bureaucrats to those of more political bureaucrats as the political and social environment changed. Based on in-depth interviews with 58 politicians and senior civil servants carried out between 2009 and 2012, we argue that Hong Kong civil service values have adapted owing in part to external shocks such as regime change and governance reform. Still, traditional civil service values such as fiscal prudence and balancing various community interests continue to be prominent. We illustrate the influence of civil service values in two policymaking cases: small-class teaching and minimum-wage legislation.
