VERTICAL SCHOOL ARCHITECTURE: A Research Manual to Support Best Practice in an Urban Context
University of Technology Sydney. Faculty of Design, Architecture and Building.City centres are becoming increasingly desirable residential locations for couples and young families, reversing a decades-old trend of population flight to outlying suburbs. As the populations of cities grow, large tracts of land which would support a traditional horizontal model of school design are no longer obtainable and are not financially viable. Therefore, for urban schools to accommodate the densification of cities, school design must transition from building outward to upward.
Vertical School Architecture is a case study analysis of the spatial planning for secondary co-educational multi-storey school models in inner-urban areas across the globe. Land economics, tight site restrictions and large accommodation briefs require a school design more aligned with high-rise construction than its suburban predecessors, posing new opportunities and challenges for the facilitation of education, student wellbeing and city-making. In this thesis, the spatial organisation patterns that emerge in vertical school design precedents are documented and considered as a resource to assist the thinking of architects, school administrations and government officials when delivering school architecture of a similar type.
Recent publications on school design focus predominately on the functional requirements of an individual space, such as the arrangement of an innovative learning environment and how it relates to its pedagogical aims. While that research is critical to understanding how learning environments should look in the twenty-first century, it does not acknowledge how all the parts of contemporary urban schools come together within a building plan and section. Therefore, the research herein endeavours to fill this gap by illustrating how the spatial diagram of vertical school precedents addresses strict site constraints to deliver a holistic, functional and connected organisational strategy
Development of a Disease-Specific Version of the EQ-5D-5L for Use in Patients Suffering from Psoriasis: Lessons Learned from a Feasibility Study in the UK
AbstractObjectivesThe EuroQol five-dimensional (EQ-5D) questionnaire is a generic measure widely used for the assessment of health status. Research has suggested that it may be insensitive to the burdens associated with particular conditions. This study was designed to explore the feasibility of developing and valuing a disease-specific âbolt-onâ version of the EQ-5D questionnaire for use in psoriasis.MethodsA series of steps were undertaken to develop, test, and evaluate dimensions for a psoriasis-specific version of the EQ-5D questionnaire (hereafter referred to as the EQ-PSO questionnaire). Candidate dimensions were explored through a review of published literature, in-depth qualitative interviews with patients, and consultation with a clinical expert. A psychometric validation exercise was then undertaken to establish how well dimensions functioned. Two dimensions were selected for inclusion in a draft measure alongside the existing EQ-5D questionnaire dimensions: âskin irritationâ and âself-confidence.â Last, a time trade-off valuation exercise was conducted with 300 members of the UK general public to derive utilities for health states described by the measure.ResultsThe psychometric analyses indicated that the two new candidate dimensions captured additional variance over and above the existing five dimensions. Data from the valuation exercise were analyzed by using different models. A collapsed random effects model was put forward as a parsimonious and accurate approach. Based on this model, estimated utilities ranged from 0.98 ± 0.02 for state â1111111â to 0.03 ± 0.29 for state â5555555.âConclusionsThis study has developed the EQ-PSO questionnaire to support future psoriasis research and has informed the development of future bolt-on versions of the EQ-5D questionnaire
A comparison of errorless and errorful therapies for dysgraphia after stroke.
Despite the increasing significance of written communication, there is limited research into spelling therapy for adults with acquired dysgraphia. Existing studies have typically measured spelling accuracy as an outcome, although speed may also be important for functional writing. As spelling is relatively slow, effortful and prone to errors in people with dysgraphia, minimising errors within therapy could be a factor in therapy success. This within-participant case-series study investigated whether errorless and errorful therapies would differ in their effects on spelling speed and accuracy for four participants with acquired dysgraphia. Matched sets of words were treated with errorless or errorful therapy or left untreated. Results were collated one week and five weeks after therapy. Both therapy approaches were successful in improving spelling accuracy. For three participants, equivalent gains were demonstrated following errorless and errorful therapy. One participant made significantly greater improvements in spelling accuracy following errorless therapy. The effects were maintained five weeks later. There was no significant difference in post-therapy spelling speed between the two therapy conditions. The results of this study suggest that both errorful and errorless therapies can be effective methods with which to treat spelling in adults with acquired dysgraphia
Balancing the benefits and risks of publicâprivate partnerships to address the global double burden of malnutrition
Objective: Transnational food, beverage and restaurant companies, and their corporate foundations, may be potential collaborators to help address complex public health nutrition challenges. While UN system guidelines are available for private-sector engagement, non-governmental organizations (NGO) have limited guidelines to navigate diverse opportunities and challenges presented by partnering with these companies through public–private partnerships (PPP) to address the global double burden of malnutrition.Design: We conducted a search of electronic databases, UN system websites and grey literature to identify resources about partnerships used to address the global double burden of malnutrition. A narrative summary provides a synthesis of the interdisciplinary literature identified.Results: We describe partnership opportunities, benefits and challenges; and tools and approaches to help NGO engage with the private sector to address global public health nutrition challenges. PPP benefits include: raising the visibility of nutrition and health on policy agendas; mobilizing funds and advocating for research; strengthening food-system processes and delivery systems; facilitating technology transfer; and expanding access to medications, vaccines, healthy food and beverage products, and nutrition assistance during humanitarian crises. PPP challenges include: balancing private commercial interests with public health interests; managing conflicts of interest; ensuring that co-branded activities support healthy products and healthy eating environments; complying with ethical codes of conduct; assessing partnership compatibility; and evaluating partnership outcomes.Conclusions: NGO should adopt a systematic and transparent approach using available tools and processes to maximize benefits and minimize risks of partnering with transnational food, beverage and restaurant companies to effectively target the global double burden of malnutrition.<br /
Comparing uni-modal and multi-modal therapies for improving writing in acquired dysgraphia after stroke.
Writing therapy studies have been predominantly uni-modal in nature; i.e., their central therapy task has typically been either writing to dictation or copying and recalling words. There has not yet been a study that has compared the effects of a uni-modal to a multi-modal writing therapy in terms of improvements to spelling accuracy. A multiple-case study with eight participants aimed to compare the effects of a uni-modal and a multi-modal therapy on the spelling accuracy of treated and untreated target words at immediate and follow-up assessment points. A cross-over design was used and within each therapy a matched set of words was targeted. These words and a matched control set were assessed before as well as immediately after each therapy and six weeks following therapy. The two approaches did not differ in their effects on spelling accuracy of treated or untreated items or degree of maintenance. All participants made significant improvements on treated and control items; however, not all improvements were maintained at follow-up. The findings suggested that multi-modal therapy did not have an advantage over uni-modal therapy for the participants in this study. Performance differences were instead driven by participant variables
School-based systems change for obesity prevention in adolescents: Outcomes of the Australian Capital Territory 'It's Your Move!'
Objective: The Australian Capital Territory âItâs Your Move!â (ACT-IYM) was a three-year (2012-
2014) systems intervention to prevent obesity among adolescents.
Methods: The ACT-IYM project involved three intervention schools and three comparison
schools and targeted secondary students aged 12-16 years. The intervention consisted of
multiple initiatives at individual, community, and school policy level to support healthier
nutrition and physical activity. Intervention school-specific objectives related to increasing
active transport, increasing time spent physically active at school, and supporting mental
wellbeing. Data were collected in 2012 and 2014 from 656 students. Anthropometric data were
objectively measured and behavioural data self-reported.
Results: Proportions of overweight or obesity were similar over time within the intervention
(24.5% baseline and 22.8% follow-up) and comparison groups (31.8% baseline and 30.6%
follow-up). Within schools, two of three the intervention schools showed a significant decrease in the prevalence of overweight and obesity (p<0.05).
Conclusions: There was some evidence of effectiveness of the systems approach to preventing obesity among adolescents. Implications for public health: The incorporation of systems thinking has been touted as the
next stage in obesity prevention and public health more broadly. These findings demonstrate
that the use of systems methods can be effective on a small scale.
Key words: Adolescence, systems intervention, obesity, weight status, schools, health

Multicenter Randomized Controlled Crossover Trial Comparing Hemodynamic Optimization Against Echocardiographic Optimization of AVÂ and VV Delay of Cardiac Resynchronization Therapy:The BRAVO Trial
Objectives: BRAVO (British Randomized Controlled Trial of AV and VV Optimization) is a multicenter, randomized, crossover, noninferiority trial comparing echocardiographic optimization of atrioventricular (AV) and interventricular delay with a noninvasive blood pressure method. Background: Cardiac resynchronization therapy including AV delay optimization confers clinical benefit, but the optimization requires time and expertise to perform. Methods: This study randomized patients to echocardiographic optimization or hemodynamic optimization using multiple-replicate beat-by-beat noninvasive blood pressure at baseline; after 6 months, participants were crossed over to the other optimization arm of the trial. The primary outcome was exercise capacity, quantified as peak exercise oxygen uptake. Secondary outcome measures were echocardiographic left ventricular (LV) remodeling, quality-of-life scores, and N-terminal proâB-type natriuretic peptide. Results: A total of 401 patients were enrolled, the median age was 69 years, 78% of patients were men, and the New York Heart Association functional class was II in 84% and III in 16%. The primary endpoint, peak oxygen uptake, met the criterion for noninferiority (pnoninferiority = 0.0001), with no significant difference between the hemodynamically optimized arm and echocardiographically optimized arm of the trial (mean difference 0.1 ml/kg/min). Secondary endpoints for noninferiority were also met for symptoms (mean difference in Minnesota score 1; pnoninferiority = 0.002) and hormonal changes (mean change in N-terminal proâB-type natriuretic peptide -10 pg/ml; pnoninferiority = 0.002). There was no significant difference in LV size (mean change in LV systolic dimension 1 mm; pnoninferiority < 0.001; LV diastolic dimension 0 mm; pnoninferiority <0.001). In 30% of patients the AV delay identified as optimal was more than 20 ms from the nominal setting of 120 ms. Conclusions: Optimization of cardiac resynchronization therapy devices by using noninvasive blood pressure is noninferior to echocardiographic optimization. Therefore, noninvasive hemodynamic optimization is an acceptable alternative that has the potential to be automated and thus more easily implemented.

Preliminary Psychometric Analyses of Two Assessment Measures Quantifying Communicative and Social Activities: the COMACT and SOCACT
Background: There is a need for clinical tools that capture the real-life impact of aphasia (Simmons-Mackie, Threats & Kagan, 2005). This study reports on a psychometric investigation of two self-report tools: the Communicative Activities Checklist and the Social Activities Checklist (COMACT; SOCACT: Cruice, 2001), which assess the dimensions of communication activity and social participation in aphasia.
Aims: (1) To investigate internal consistency, convergent and known validity of the COMACT and SOCACT; and (2) To investigate the impact of personal contextual factors: gender, age, years in education, linguistic ability and emotional health on communicative and social activities.
Method: 30 participants with mild-moderate chronic aphasia (PWA: mean age 71 years, mean time post-onset 41 months, mean years in education 10.77) and 75 control neurologically healthy participants (NHP: mean age 74 years, mean years in education 13.18) completed the COMACT and SOCACT reporting how frequently they engaged in particular activities. The COMACT has 45 communication activities with sub-scales of Talking, Listening, Reading and Writing. The SOCACT contains 20 social activities with sub-scales of Leisure, Informal and Formal. Internal consistency (IC) was examined using Cronbachâs alpha (α). Correlations with published assessments, Western Aphasia Battery (WAB: Kertesz, 1982) and Communication Activities of Daily Living (CADL-2: Holland, Frattali & Fromm, 1999) were computed for COMACT only. Multiple regression models were examined for differences in participant (PWA vs. NHP) performance on COMACT and SOCACT. COMACT & SOCACT: psychometric investigation
Results: Total COMACT IC was 0.83 (PWA), and 0.84 (NHP). Following deletion of four items, to further improve sub-scale ICs, total COMACT IC was 0.83 (PWA) and 0.86 (NHP). COMACT total score and WAB AQ were moderately correlated (r = 0.55). Total SOCACT IC was 0.58 (PWA) and 0.63 (NHP). Following single item deletion, total IC was 0.65 (PWA) and 0.64 (NHP). Statistical analysis revealed PWA, in comparison to NHP, participated in significantly fewer communication and social activities. Personal contextual factors impacted both groups differently; particular aspects were associated with communication activity (age and language severity) and social activity (age only). For NHP, ageing, emotional health and years in education were significant predictors of social and communication activity.
Conclusion: This study finds the COMACT to be a reliable, valid measure of communication activity. The SOCACT had âquestionableâ IC and requires further psychometric investigation. Both tools demonstrate known group validity. Relationships between impairment-level and personal contextual factors for communication activity and social participation are highlighted
